Moxibustion on herbs, a common complementary and alternative medicine approach, is frequently used for treating AR in clinical practice. Western medicine is good at quick symptomatic relief,while offer little or no sustainable and steady long-term effect. Little established evidence is available to support the long-term effectiveness of moxibustion on herbs for AR.Objective： This study is a randomized controlled trial to assess the long-term effectiveness of moxibustion on herbs in moderate-severe persistent AR population.Methods： The study sample size is 56 patients. Eligible patients with moderate-severe persistent AR will be randomized into a moxibustion on herbs combined with conventional treatment group（MOHCT group） and a conventional treatment group（CT group） in a 1：1 ratio. Patients in the MOHCT group will receive a 30-min moxibustion on herbs treatment on Zhiyang（至阳 GV 9）, Dàzhuī（大椎 GV 14） and bilateral Shenshu（肾俞 BL 23）, Fèishū（肺俞 BL 13） for a total of 12 times on the basis of conventional treatment, while those in the CT group will receive conventional treatment alone. The primary outcome measure is VAS score for total nasal symptoms, which will be obtained via a self-recorded AR diary. The secondary outcome measures include the average occurrence of symptoms per week, use of medication and Rhinoconjunctivitis Quality of Life Questionnaire（RQLQ）.Discussion： The objectives of this study include（1） to evaluate the long-term effectiveness and safety of moxibustion on herbs for treating AR;（2） to evaluate whether moxibustion on herbs can reduce the frequency of AR symptoms in patients with moderate-severe persistent allergic rhinitis. The finding of this study will provide evidence on the long-term effectiveness of moxibustion on herbs for moderatesevere persistent AR.展开更多

Infection control policies are crucial for controlling CDI, but there are currently no regulatory guidelines in the United States. Therefore, we evaluated infection control policies in local LTCFs to define the CDI-specific policies and the administrative and staff understanding of CDI, so as to identify perceived barriers for compliance. Methods: IRB approval was sought and exemption granted, all 8 local LTCFs were asked to participate. Each facility was visited by study personnel who interviewed the administrative Infection Control Practitioner (ICP) and 3-4 Licensed Practical Nurses (LPNs) with distinct survey format. Infection control policies were then compared to the SHEA recommendations for CDI in LTCFs. Results: Of the eligible facilities, 75% (n = 6) participated. ICP (n = 6) and LPNs (n = 21) were interviewed. All facilities accept residents with active CDI and 2 had written CDI-specific infection control policies. All facilities had hand hygiene or glove use policies and 2 had policies for the use of sporicidal environmental cleaning. No facility restricted antibiotic use. Each facility has a policy to instruct their staff through in-services, either annually or upon new hire, but 33% (n = 7) LPNs reported no facility-based CDI training. While 80% (n = 17) of LPNs felt comfortable with the facility CDI policies, only 11 accurately restated it. ICPs felt the most relevant barrier to staff compliance was time constraints (n = 4, 67%), however, LPNs felt it was limited knowledge (n = 10, 48%) and poor communication (n = 2, 10%). Discussion and Conclusions: With the increasing incidence and severity of CDI in LCTF, few of the facilities surveyed had CDI-specific policies. Despite CDI-specific training, there is a perceived knowledge and communication gap for staff caring for residents with CDI.展开更多

We aimed to study the factors associated with prolonged poor diabetes control in the cohort of T2DM patients monitored and treated in the Department of Internal Medicine at the Yalgado OUEDRAOGO Teaching Hospital in Ouagadougou in order to optimize therapeutic education in these patients. </span><b><i><span>Methodology</span></i></b><span>: This was a descriptive and analytical cross-sectional study combining retrospective data collection from the last year of patient follow-up and prospective collection of some information. The study included all diabetic patients, aged at least 18 years old, followed and treated in the Department of Internal Medicine at the Yalgado OUEDRAOGO Teaching Hospital between January 1, 2010 and December 31, 2018 following a systematic random sampling with a sampling step of 10. The variables collected were sociodemographic, anthropometric, lifestyle, cardiovascular risk factors and diabetes-related characteristics. To determine the risk factors associated with prolonged poor glycemic control, we performed modeling using logistic regression. All variables associated with prolonged poor glycemic control, in bivariate logistic regression with a p-value less than 0.20 were included in the full model. Later, we used a stepwise descending method to obtain the final model, which was then tested by a receiver operating characteristic (ROC) curve. The significance threshold was set at 5%. Raw and fitted Odds-Ratio (OR) and 95% confidence interval were presented. </span><b><i><span>Results</span></i></b><span>: 270 patients were included. Prolonged poor control of diabetes mellitus was observed in 73.70%. The mean age was 55.97 years (SD: ±11.52) and the sex ratio was 0.6 in favor of female. The mean time since diabetes mellitus diagnoses was 5.85 years (SD: ±5.15). A monthly gain of 92.62 USD (50.74%) for average diabetes mellitus care expenditures of 55.82 USD (SD: 28.25) was reported. An overweight (55.92%) and hypertension (41.85%) were reported. Diabetes mellitus was complicated in 68.15%. Patients were supported by their families in the management of their diabetes mellitus in 85.19%.

Iron reduction upregulates glucose uptake and improves hepatocytes insulin receptor activity. This study was conducted to examine the effects of iron depletion—via controlled phlebotomy—on the hypoglycemic treatment in poorly controlled type 2 diabetes mellitus (T2DM) patients with non-genetic iron overload. Forty three patients with poorly controlled T2DM and iron overload were divided into 2 groups: iron depletion group and control group. Regular phlebotomy was performed for iron depletion group on monthly basis until serum ferritin reached 20 μg/L or less. Both groups were examined and compared for blood pressure, serum ferritin, lipid profile, HFE-gene, HbA1c, HOMA-IR and number of medicines used for diabetic control. The results had revealed that group differences of HbA1c (-2.64, 95% CI -3.23 to 2.04, p < 0.001) and HOMA-IR (-0.68, 95% CI -0.98 to -0.37, p < 0.001) showed significant decreases in iron depletion group at end of study. Significant decrease in the numbers of hypoglycemic medicines in iron depletion group was shown at end of study (p < 0.001);66.7% of iron depletion group patients were receiving 1 or 2 medicines at end of studyversus none of the control group. Diastolic blood pressure (DBP), triglycerides and LDL-C decreased significantly while HDL-C levels showed significant rise after iron depletion. It can be concluded from the present study that iron depletion therapy is beneficial for improving the efficiency of glycemic control, DBP, and dyslipidemia in poorly controlled type 2 diabetics with iron over load.展开更多

With this approach,we can suppress the fast disturbance and slow drifting of optical fiber to satisfy the requirements of optical phase long-term locking. In theory,a mathematical model of an optical fiber phase control system is established. The disturbance term induced by environment influence is considered into the PLL model. The monotonous and continuous changing environment disturbance w ill cause a steady-state error in this theory model. The experimental results accords w ell w ith the theory. The steady-state performance,adjusting time,and overshoot can be improved by using the dual PID control. As a result,the long-term,highly stable and low noise fiber phase locking is realized experimentally.展开更多

We aim to determine the frequency of uncontrolled hypertension in hypertensive patients followed up as an outpatient at the campus university hospital of Lome (Togo) and to search for the associated factors. Methodology: The study was cross-sectional, descriptive and analytical, carried out from February (2022) to August 2022 in 260 hypertensive patients aged 22 years old, followed up (on an) as an outpatient for at least 3 months at the Lome University Hospital campus. A univariate then multivariate analysis were conducted in order to highlight the most common factors significantly linked to uncontrolled. Results: The mean age of hypertensives was 56.4 ± 12.7 years, the sex ratio (M/F) was 0.59. Prevalence of uncontrolled blood pressure was 42%. Associated Factors to poor blood pressure control in our study were age > 60 years (OR = 1.6 CI [1.17 - 2.50]), low socio-economic level (OR = 2.2 CI [1.96 - 4.33]), high cardiovascular risk level (OR = 3.1 CI [2.18 - 4.52]), non-adherence to regular blood pressure monitoring (OR = 3.3 CI [2.21 - 5.55]), low compliance to treatment (OR = 4.1 CI [2.33 - 6.76]) and a chronic renal failure (OR = 2.1 CI [1.21 - 3.10]). Conclusion: Nearly half of the hypertensives in our study had poorly controlled blood pressure by antihypertensive treatment medication. The factors of this poor control were age > 60 years, low socio-economic level, high or very high level of cardiovascular risk, low compliance to treatment, and renal failure.展开更多

Methods: This is a prospective analytic transversal study with 214 survivors of Bone Marrow Transplant (BMT) and 264 healthy people identified among blood donors, treated as the control group, of both sexes, 18 years or older. The protocol includes a demographic-socioeconomic questionnaire, World Health Organization Quality of Life (WHOQOL) and the Karnofsky Performance Status Scale. Results: 53.7% of the survivor group members are satisfied with their QoL. A similar result can be found in the control group (54.2%). Chronological maturity, anxiety, sexual difficulty, and being a provider are factors that interfere negatively in the QoL of male survivors. In female survivors, the risk factors are anxiety, low educational level, not having a stable partner, being a provider, and not being Caucasian. Conclusions: Survivors are as satisfied with their QoL as the control group. QoL is understood as a perceptive process composed of objective (functional and relational capacity) and subjective phenomenon (perceptive composition).展开更多

The objective of the present study was to evaluate the clinical outcomes of successful implementation of an employer initiated community pharmacist-based disease management program for diabetic patients with poorly controlled diabetes. Methods： Employees with poorly controlled diabetes （glycosylated hemoglobin （A1 C） level 〉 7.5%） were identified fi＇om a large diabetes disease management program, in a rural setting in Texas, US. A longitudinal retrospective study was conducted, analyzing clinical indicators in the diabetes patients following the community pharmacist-based disease management program. The program involved a comprehensive drug therapy assessment and individualized disease management education. Primary outcome measured in the present study was A1C levels, assessed at the baseline visit and at the end of the intervention. Results： A total of 64 patients with poorly controlled diabetes were identified. Significant improvement in mean clinical outcome scores was achieved for A1C levels （p = 0.0011）. At the end of the 1 year longitudinal intervention, targeted body mass index and A1C goals were attained by 35.9% （p 〈 0.001） and 15.6% patients, respectively. The 10 patients reaching goal levels post intervention were in the group that had baseline A1C of 7.5 to 9%. However, patients with 〉 9% A1C levels at baseline had a significant reduction （mean 2.1, p 〈 0.001） post intervention. Conclusion： The community pharmacist-based diabetes disease management program improved A1C levels of patients with poorly controlled diabetes.展开更多

Methods: in order to control the patients' insulin, 120 patients with "type 2 diabetes" who visited our hospital from June 2019 to June 2020 were selected for this study. They were divided into the control group (conventional treatment method) and the observation group (based on conventional treatment, combined with Dapagliflozin for 12 months to track the therapeutic management effect). Compare the blood glucose index and adverse reactions before and after treatment. Results: through treatment, it was found that the patients in the observation group were significantly better than those in the control group in the observation of the average level, maximum fluctuation range, standard deviation and other aspects of blood glucose test, the overall treatment effect and the incidence of adverse reactions. The total effective rate of the patients in the observation group was significantly better than that of the control group, and the comparison effect and data difference between the two groups were statistically significant (P > 0.05). Conclusion: after systematic treatment of diabetic patients, Dapagliflozin is used to treat the blood glucose test level of "type 2 diabetes" patients, thus effectively controlling the adverse reactions such as blood glucose lowering index and hypoglycemia caused by blood glucose fluctuation.展开更多

DATA ReTRIevAL： We retrieved relevant random and semi-random controlled trials that used theXingnao Kaiqiao needling method to treat ischemic stroke compared with various control treatments such as conventional drugs or other acupuncture therapies. Searched databases included China National Knowledge Infrastructure, Weipu Information Resources System, Wanfang Medical Data System, Chinese Biomedical Literature Database, Cochrane Library, and PubMed, from May 2006 to July 2014. SeLeCTION CRITeRIA： Two authors independently conducted literature screening, quality evaluation, and data extraction. The quality of articles was evaluated according to the Cochrane Reviewers’ Handbook 5.1, and the study was carried out using Cochrane system assessment methods. RevMan 5.2 was used for meta-analysis of the included studies. MAIN OUTCOMe MeASUReS： Mortality rate, recurrence rate, and disability rate were observed. ReSULTS：Nine randomized and semi-randomized controlled trials treating 931 cases of ischemic stroke were included in this review. Meta-analysis results showed that there were no sig-niifcant differences in mortality reduction （risk ratio （RR） = 0.58, 95% conifdence interval （CI）： 0.17–1.93,Z = 0.89,P = 0.37） or recurrence rate （RR = 0.55, 95%CI： 0.18–1.70,Z = 1.04,P = 0.30） of ischemic stroke patients between theXingnao Kaiqiao needling and control treatment groups. However, theXingnao Kaiqiao needling method had a tendency towards higher efifcacy in mor-tality reduction and recurrence rates. TheXingnao Kaiqiao needling method was signiifcantly better than that of the control treatment in reducing disability rate （RR = 0.51, 95%CI： 0.27–0.98, Z = 2.03,P 〈 0.05）. CONCLUSION：TheXingnao Kaiqiao needling method has a better effect than control treatment in reducing disability rate. The long-term effect ofXingnao Kaiqiao needling against ischemic stroke is better than that of control treatment. However, the limitations of this study limit the strength of the conclusions. Randomized controlled trials with a strict, reasonable design, and multi-center, large-scale samples and follow-up are necessary to draw conclusions aboutXingnao Kaiqiao needling.展开更多

The purpose of this paper is to describe the design of an auto-calibrating system for electrochemical (pH) sensors, which permits two-point in situ calibration, suitable for long-term measurement in deep sea aqueous environments. Holding multiple sensors, the instrument is designed to perform long-term measurements and in situ calibrations at abyssal depth (up to 4000 m). The instrument is composed of a compact fluid control system which is pressure-equilibrated and designed for deep-sea operation. In situ calibration capability plays a key role in the quality and reproducibility of the data. This paper focuses on methods for extending the lifetime of the instrument, considering the fluidics design, mechanical design, and low-power consumption of the electronics controller. The instrument can last 46 d under normal operating conditions, fulfilling the need for long-term operation. Data concerning pH measured during the KNOX18RR cruise (Mid-Atlantic Ridge, July-August, 2008) illustrate the desirable properties of the instrument. Combined with different electrodes (pH, H2, H2S, etc.), it should be of great utility for the study of deep ocean environments, including water column and diffuse-flow hydrothermal fluids.展开更多

文摘Introduction: The incidence and severity of Clostridium difficile infection (CDI) has been increasing and long-term care facility (LTCF) residents are at high risk given their age, co-morbidities, and high antibiotic exposure. Infection control policies are crucial for controlling CDI, but there are currently no regulatory guidelines in the United States. Therefore, we evaluated infection control policies in local LTCFs to define the CDI-specific policies and the administrative and staff understanding of CDI, so as to identify perceived barriers for compliance. Methods: IRB approval was sought and exemption granted, all 8 local LTCFs were asked to participate. Each facility was visited by study personnel who interviewed the administrative Infection Control Practitioner (ICP) and 3-4 Licensed Practical Nurses (LPNs) with distinct survey format. Infection control policies were then compared to the SHEA recommendations for CDI in LTCFs. Results: Of the eligible facilities, 75% (n = 6) participated. ICP (n = 6) and LPNs (n = 21) were interviewed. All facilities accept residents with active CDI and 2 had written CDI-specific infection control policies. All facilities had hand hygiene or glove use policies and 2 had policies for the use of sporicidal environmental cleaning. No facility restricted antibiotic use. Each facility has a policy to instruct their staff through in-services, either annually or upon new hire, but 33% (n = 7) LPNs reported no facility-based CDI training. While 80% (n = 17) of LPNs felt comfortable with the facility CDI policies, only 11 accurately restated it. ICPs felt the most relevant barrier to staff compliance was time constraints (n = 4, 67%), however, LPNs felt it was limited knowledge (n = 10, 48%) and poor communication (n = 2, 10%). Discussion and Conclusions: With the increasing incidence and severity of CDI in LCTF, few of the facilities surveyed had CDI-specific policies. Despite CDI-specific training, there is a perceived knowledge and communication gap for staff caring for residents with CDI.
文摘<b><i><span>Background</span></i></b><span>: Achieving and maintaining glycemic targets </span><span>are</span><span> a challenge for health practitioners around the world. We aimed to study the factors associated with prolonged poor diabetes control in the cohort of T2DM patients monitored and treated in the Department of Internal Medicine at the Yalgado OUEDRAOGO Teaching Hospital in Ouagadougou in order to optimize therapeutic education in these patients. </span><b><i><span>Methodology</span></i></b><span>: This was a descriptive and analytical cross-sectional study combining retrospective data collection from the last year of patient follow-up and prospective collection of some information. The study included all diabetic patients, aged at least 18 years old, followed and treated in the Department of Internal Medicine at the Yalgado OUEDRAOGO Teaching Hospital between January 1, 2010 and December 31, 2018 following a systematic random sampling with a sampling step of 10. The variables collected were sociodemographic, anthropometric, lifestyle, cardiovascular risk factors and diabetes-related characteristics. To determine the risk factors associated with prolonged poor glycemic control, we performed modeling using logistic regression. All variables associated with prolonged poor glycemic control, in bivariate logistic regression with a p-value less than 0.20 were included in the full model. Later, we used a stepwise descending method to obtain the final model, which was then tested by a receiver operating characteristic (ROC) curve. The significance threshold was set at 5%. Raw and fitted Odds-Ratio (OR) and 95% confidence interval were presented. </span><b><i><span>Results</span></i></b><span>: 270 patients were included. Prolonged poor control of diabetes mellitus was observed in 73.70%. The mean age was 55.97 years (SD: ±11.52) and the sex ratio was 0.6 in favor of female. The mean time since diabetes mellitus diagnoses was 5.85 years (SD: ±5.15). A monthly gain of 92.62 USD (50.74%) for average diabetes mellitus care expenditures of 55.82 USD (SD: 28.25) was reported. An overweight (55.92%) and hypertension (41.85%) were reported. Diabetes mellitus was complicated in 68.15%. Patients were supported by their families in the management of their diabetes mellitus in 85.19%. In multivariate analysis with bivariate logistic regression, low level of formal education (OR = 8.34, 95% CI [1.97 - 35.22];</span><i><span>p</span></i><span> < 0.01), family support for diabetes mellitus management (OR = 0.65, 95% CI [0.45 - 0.94];</span><i><span>p</span></i><span> = 0.02), presence of abdominal obesity (OR = 2.27, 95% CI [1.08 - 4.77];</span><i><span>p</span></i><span> = 0.03), presence of a history of hospitalization (OR = 7.39, 95% CI [2.97 - 18.39];</span><i><span>p</span></i><span> < 0.01), poor adherence to antidiabetic treatment (OR = 2.97, 95% CI [1.42 - 6.18];</span><i><span>p</span></i><span> < 0.01), and the presence of microangiopathy (OR = 5.05, 95% CI [2.36 - 10.81];</span><i><span>p</span></i><span> < 0.01) were the factors independently associated with prolonged poor control of T2DM, with a ROC curve of 0.88, which reflects a very good sensitivity and specificity of these factors. </span><b><i><span>Conclusion</span></i></b><b><span>: </span></b><span>The imbalance of T2DM is multifactorial.

文摘Iron overload increases the risk of diabetes via mechanisms of abnormal glucose metabolism: insulin deficiency, insulin resistance, and/or hepatic dysfunction. Iron reduction upregulates glucose uptake and improves hepatocytes insulin receptor activity. This study was conducted to examine the effects of iron depletion—via controlled phlebotomy—on the hypoglycemic treatment in poorly controlled type 2 diabetes mellitus (T2DM) patients with non-genetic iron overload. Forty three patients with poorly controlled T2DM and iron overload were divided into 2 groups: iron depletion group and control group. Regular phlebotomy was performed for iron depletion group on monthly basis until serum ferritin reached 20 μg/L or less. Both groups were examined and compared for blood pressure, serum ferritin, lipid profile, HFE-gene, HbA1c, HOMA-IR and number of medicines used for diabetic control. The results had revealed that group differences of HbA1c (-2.64, 95% CI -3.23 to 2.04, p < 0.001) and HOMA-IR (-0.68, 95% CI -0.98 to -0.37, p < 0.001) showed significant decreases in iron depletion group at end of study. Significant decrease in the numbers of hypoglycemic medicines in iron depletion group was shown at end of study (p < 0.001);66.7% of iron depletion group patients were receiving 1 or 2 medicines at end of studyversus none of the control group. Diastolic blood pressure (DBP), triglycerides and LDL-C decreased significantly while HDL-C levels showed significant rise after iron depletion. It can be concluded from the present study that iron depletion therapy is beneficial for improving the efficiency of glycemic control, DBP, and dyslipidemia in poorly controlled type 2 diabetics with iron over load.

文摘We propose an approach of long-term stabilization of optical fiber phase by controlling a piezo-based phase modulator and a Peltier component attached to the fiber via a phase-locked loop( PLL) circuit w ith dual proportional-integral- derivative( PID) adjustment. With this approach,we can suppress the fast disturbance and slow drifting of optical fiber to satisfy the requirements of optical phase long-term locking. In theory,a mathematical model of an optical fiber phase control system is established. The disturbance term induced by environment influence is considered into the PLL model. The monotonous and continuous changing environment disturbance w ill cause a steady-state error in this theory model. The experimental results accords w ell w ith the theory. The steady-state performance,adjusting time,and overshoot can be improved by using the dual PID control. As a result,the long-term,highly stable and low noise fiber phase locking is realized experimentally.
文摘Introduction: Hypertension is a real public health issue and its control is very difficult. We aim to determine the frequency of uncontrolled hypertension in hypertensive patients followed up as an outpatient at the campus university hospital of Lome (Togo) and to search for the associated factors. Methodology: The study was cross-sectional, descriptive and analytical, carried out from February (2022) to August 2022 in 260 hypertensive patients aged 22 years old, followed up (on an) as an outpatient for at least 3 months at the Lome University Hospital campus. A univariate then multivariate analysis were conducted in order to highlight the most common factors significantly linked to uncontrolled. Results: The mean age of hypertensives was 56.4 ± 12.7 years, the sex ratio (M/F) was 0.59. Prevalence of uncontrolled blood pressure was 42%. Associated Factors to poor blood pressure control in our study were age > 60 years (OR = 1.6 CI [1.17 - 2.50]), low socio-economic level (OR = 2.2 CI [1.96 - 4.33]), high cardiovascular risk level (OR = 3.1 CI [2.18 - 4.52]), non-adherence to regular blood pressure monitoring (OR = 3.3 CI [2.21 - 5.55]), low compliance to treatment (OR = 4.1 CI [2.33 - 6.76]) and a chronic renal failure (OR = 2.1 CI [1.21 - 3.10]). Conclusion: Nearly half of the hypertensives in our study had poorly controlled blood pressure by antihypertensive treatment medication. The factors of this poor control were age > 60 years, low socio-economic level, high or very high level of cardiovascular risk, low compliance to treatment, and renal failure.
文摘Purpose: To evaluate the global quality of life (QoL) of survivors with 10-year or more post-transplant, and to identify risk factors that interfere with well-being. Methods: This is a prospective analytic transversal study with 214 survivors of Bone Marrow Transplant (BMT) and 264 healthy people identified among blood donors, treated as the control group, of both sexes, 18 years or older. The protocol includes a demographic-socioeconomic questionnaire, World Health Organization Quality of Life (WHOQOL) and the Karnofsky Performance Status Scale. Results: 53.7% of the survivor group members are satisfied with their QoL. A similar result can be found in the control group (54.2%). Chronological maturity, anxiety, sexual difficulty, and being a provider are factors that interfere negatively in the QoL of male survivors. In female survivors, the risk factors are anxiety, low educational level, not having a stable partner, being a provider, and not being Caucasian. Conclusions: Survivors are as satisfied with their QoL as the control group. QoL is understood as a perceptive process composed of objective (functional and relational capacity) and subjective phenomenon (perceptive composition).
文摘Objective： Patients with poorly controlled diabetes have more medical complications and are more difficult to manage. The objective of the present study was to evaluate the clinical outcomes of successful implementation of an employer initiated community pharmacist-based disease management program for diabetic patients with poorly controlled diabetes. Methods： Employees with poorly controlled diabetes （glycosylated hemoglobin （A1 C） level 〉 7.5%） were identified fi＇om a large diabetes disease management program, in a rural setting in Texas, US. A longitudinal retrospective study was conducted, analyzing clinical indicators in the diabetes patients following the community pharmacist-based disease management program. The program involved a comprehensive drug therapy assessment and individualized disease management education. Primary outcome measured in the present study was A1C levels, assessed at the baseline visit and at the end of the intervention. Results： A total of 64 patients with poorly controlled diabetes were identified. Significant improvement in mean clinical outcome scores was achieved for A1C levels （p = 0.0011）. At the end of the 1 year longitudinal intervention, targeted body mass index and A1C goals were attained by 35.9% （p 〈 0.001） and 15.6% patients, respectively. The 10 patients reaching goal levels post intervention were in the group that had baseline A1C of 7.5 to 9%. However, patients with 〉 9% A1C levels at baseline had a significant reduction （mean 2.1, p 〈 0.001） post intervention. Conclusion： The community pharmacist-based diabetes disease management program improved A1C levels of patients with poorly controlled diabetes.
文摘Objective: to study the overall effect of drug therapy for patients with "type 2 diabetes" who have poor blood glucose control by Dapagliflozin control. Methods: in order to control the patients' insulin, 120 patients with "type 2 diabetes" who visited our hospital from June 2019 to June 2020 were selected for this study. They were divided into the control group (conventional treatment method) and the observation group (based on conventional treatment, combined with Dapagliflozin for 12 months to track the therapeutic management effect). Compare the blood glucose index and adverse reactions before and after treatment. Results: through treatment, it was found that the patients in the observation group were significantly better than those in the control group in the observation of the average level, maximum fluctuation range, standard deviation and other aspects of blood glucose test, the overall treatment effect and the incidence of adverse reactions. The total effective rate of the patients in the observation group was significantly better than that of the control group, and the comparison effect and data difference between the two groups were statistically significant (P > 0.05). Conclusion: after systematic treatment of diabetic patients, Dapagliflozin is used to treat the blood glucose test level of "type 2 diabetes" patients, thus effectively controlling the adverse reactions such as blood glucose lowering index and hypoglycemia caused by blood glucose fluctuation.

文摘OBJeCTIve：To systematically evaluate the long-term effect and safety ofXingnao Kaiqiao nee-dling method in ischemic stroke treatment. DATA ReTRIevAL： We retrieved relevant random and semi-random controlled trials that used theXingnao Kaiqiao needling method to treat ischemic stroke compared with various control treatments such as conventional drugs or other acupuncture therapies. Searched databases included China National Knowledge Infrastructure, Weipu Information Resources System, Wanfang Medical Data System, Chinese Biomedical Literature Database, Cochrane Library, and PubMed, from May 2006 to July 2014. SeLeCTION CRITeRIA： Two authors independently conducted literature screening, quality evaluation, and data extraction. The quality of articles was evaluated according to the Cochrane Reviewers’ Handbook 5.1, and the study was carried out using Cochrane system assessment methods. RevMan 5.2 was used for meta-analysis of the included studies. MAIN OUTCOMe MeASUReS： Mortality rate, recurrence rate, and disability rate were observed. ReSULTS：Nine randomized and semi-randomized controlled trials treating 931 cases of ischemic stroke were included in this review. Meta-analysis results showed that there were no sig-niifcant differences in mortality reduction （risk ratio （RR） = 0.58, 95% conifdence interval （CI）： 0.17–1.93,Z = 0.89,P = 0.37） or recurrence rate （RR = 0.55, 95%CI： 0.18–1.70,Z = 1.04,P = 0.30） of ischemic stroke patients between theXingnao Kaiqiao needling and control treatment groups. However, theXingnao Kaiqiao needling method had a tendency towards higher efifcacy in mor-tality reduction and recurrence rates. TheXingnao Kaiqiao needling method was signiifcantly better than that of the control treatment in reducing disability rate （RR = 0.51, 95%CI： 0.27–0.98, Z = 2.03,P 〈 0.05）. CONCLUSION：TheXingnao Kaiqiao needling method has a better effect than control treatment in reducing disability rate. The long-term effect ofXingnao Kaiqiao needling against ischemic stroke is better than that of control treatment. However, the limitations of this study limit the strength of the conclusions. Randomized controlled trials with a strict, reasonable design, and multi-center, large-scale samples and follow-up are necessary to draw conclusions aboutXingnao Kaiqiao needling.

文摘An in situ calibration system is a versatile exploration instrument for electrochemical sensors investigating the biochemical properties of the marine environment. The purpose of this paper is to describe the design of an auto-calibrating system for electrochemical (pH) sensors, which permits two-point in situ calibration, suitable for long-term measurement in deep sea aqueous environments. Holding multiple sensors, the instrument is designed to perform long-term measurements and in situ calibrations at abyssal depth (up to 4000 m). The instrument is composed of a compact fluid control system which is pressure-equilibrated and designed for deep-sea operation. In situ calibration capability plays a key role in the quality and reproducibility of the data. This paper focuses on methods for extending the lifetime of the instrument, considering the fluidics design, mechanical design, and low-power consumption of the electronics controller. The instrument can last 46 d under normal operating conditions, fulfilling the need for long-term operation. Data concerning pH measured during the KNOX18RR cruise (Mid-Atlantic Ridge, July-August, 2008) illustrate the desirable properties of the instrument. Combined with different electrodes (pH, H2, H2S, etc.), it should be of great utility for the study of deep ocean environments, including water column and diffuse-flow hydrothermal fluids.
