The predominance of female breast cancer (30%) aligns with global trends, underscoring the need for robust diagnostic protocols, particularly in developing regions. Other prevalent cancers, including skin, stomach, and cervix uteri, reflect a mix of environmental, genetic, and infectious factors. The underrepresentation of gallbladder and thyroid cancers (<1%) suggests potential underdiagnosis or lower prevalence. Age distribution data indicate peak cancer incidence in individuals aged 31 - 45 years, with gender-specific cancers like breast and cervical cancer predominantly affecting females (63.4%). The analysis also highlights significant diagnostic gaps, as 61.2% of cases did not undergo IHC testing due to resource constraints, leading to potential biases in cancer prevalence and diagnostic accuracy. The study emphasizes the complementary role of IHC in confirming ambiguous H&E findings, with strong alignment observed when both methods were used. However, the absence of IHC in many cases limits the robustness of conclusions, suggesting the need for increased access to IHC testing. The findings advocate for integrating IHC into routine diagnostics, expanding diagnostic capabilities, and improving sample sizes to ensure more reliable and comprehensive cancer data.展开更多

[Method] Pectinase was used to decompose cell wall materials in tobacco stems, followed by determination of the contents of four cell wall materials, six routine chemical components, as well as aroma constituents. [Result] Pectinase could effectively reduce the contents of cell wall materials in tobacco stems, with the largest decrease of 6.84%; after pectinase treatment,the content of reducing sugar in tobacco stems increased obviously, and the contents of total sugar, potassium ion, chloride ion and total nitrogen increased to varying degrees, of which the contents of potassium ion and reducing sugar displayed upward trends with the increase of pectinase concentration. Pectinase treatment significantly increased the contents of Maillard reaction products, with the most increase of 67.2%;the contents of carotenoid degradation products, phenylalanine degradation products and neophytadiene all increased to varying extents, and the contents of both Maillard reaction products and phenylalanine degradation products revealed ascending trends with the increase of pectinase concentration. [Conclusion] Pectinase treatment can effectively decompose cell wall materials in tobacco stems, improve routine chemical constituents, and increase the contents of aroma constituents.展开更多

However, the amplitude and spatial distribution of the velocity variation remains a controversial issue. Recent active source monitoring carried out adjacent to Wenchuan Fault Scientific Drilling （WFSD） revealed unambiguous coseismic velocity change associated with a local M8 5.5 earthquake. Here, we carry out forward modeling using two-dimensional spectral element method to further investigate the amplitude and spatial distribution of observed velocity change. The model is well constrained by results from seismic reflection and WFSD coring. Our model strongly suggests that the observed coseismic velocity change is localized within the fault zone with width of ~ 120 m rather than dynamic strong ground shaking. And a velocity decrease of -2.0 % within the fault zone is required to fit the observed travel time delay distribution, which coincides with rock mechanical experiment and theoretical modeling.展开更多

文摘BACKGROUND Acute respiratory infections(ARI)and diarrhoea are among the leading causes of infant and under-five mortality worldwide.Zinc,the second most abundant trace element in the human body,is widely used in the treatment of both conditions.It mitigates diarrhoea by restoring mucosal integrity and enhancing enterocyte brush border enzyme activity.In ARI,zinc boosts immune function,promotes epithelial regeneration,and inhibits the replication of respiratory viruses.AIM To assess the effectiveness of prophylactic intermittent zinc supplementation in preventing acute diarrhoea and ARI in infants.METHODS This open-label,randomized controlled trial with a 1:1 allocation ratio was conducted over 15 months(October 2022 to December 2023)at a tertiary care hospital in Eastern India.A total of 320 infants attending the outpatient department for routine vaccinations were enrolled and randomly assigned to intervention and control groups.The intervention group received zinc drops for two weeks,with the regimen repeated one month later and again at six months during subsequent vaccination visits.The control group received no placebo or alternative treatment.Outcomes were assessed after the final follow-up at nine months.RESULTS The mean annual incidence of ARI and diarrhoea was significantly lower in the zinc group than in the control group[ARI:0.25±0.61 vs 0.92±1.22;mean difference=-0.67(95%CI:-0.88 to-0.45),P<0.001,Cohen’s d=-0.69]and[diarrhoea:1.04±1.30 vs 2.07±2.09;mean difference=-1.03(95%CI:-1.42 to-0.65),P<0.001,Cohen's d=-0.59],respectively.Additionally,the zinc group showed significantly greater gains in length[10±0.6 cm vs 8.6±0.4 cm;mean difference=1.4(95%CI:1.3-1.5),P<0.001,Cohen’s d=2.74]and weight[3150±108 g vs 2818±76 g;mean difference=332(95%CI:310-352),P<0.001,Cohen's d=3.56].CONCLUSION Prophylactic intermittent zinc supplementation administered alongside routine immunization substantially reduces the incidence of ARI and diarrhoea in infants and promotes improved growth.This affordable strategy holds promise for reducing infant morbidity and mortality without increasing healthcare burdens.
文摘Objective:To compare the nursing effects of routine care and specialized nursing intervention on patients with dysphagia during acute stroke.Methods:A total of 188 patients with acute stroke and dysphagia who received treatment at our hospital from May 2022 to December 2024 were selected as study subjects.The patients were randomly divided into a control group and an observation group,with 94 patients in each group.The control group received routine nursing intervention,while the observation group received specialized nursing intervention.The general information,swallowing function,quality of life,and nursing satisfaction were compared between the two groups.Results:There was no statistically significant difference in general information between the two groups(P>0.05).The SAS score of the observation group after nursing was significantly lower than that of the control group(t=19.463,P=0.000<0.001).After intervention,the number of patients with lung infection in the observation group was significantly lower than that in the control group(χ2=7.309,P=0.007<0.01).The overall quality of life score of the observation group was significantly better than that of the control group after intervention(P<0.001).The nursing satisfaction of the observation group was significantly higher than that of the control group(χ^(2)=15.865,P=0.000<0.001).Conclusion:Compared with routine care,specialized nursing intervention can effectively improve the swallowing function of patients with dysphagia during acute stroke,enhance their quality of life,and increase nursing satisfaction.

文摘BACKGROUND Narrative nursing uses narrative methods to establish an interaction between nursing staff and patients,in which the experience of the patient’s illness is understood and comprehended.By listening,the patient’s understanding,comprehension,and acceptance of their own disease symptoms,quality of life,and living conditions are understood,thereby providing a basis for formulating corresponding nursing plans for the patient,further promoting the psychological and physical rehabilitation of the patient.AIM To explore the impact of the new narrative nursing model on postoperative recovery,psychological status,and satisfaction of patients.METHODS A total of 108 patients with resectable gastric cancer who were treated from January 2024 to December 2024 were selected as the study subjects.They were divided into a routine nursing group and a narrative nursing group using a random number table method.Postoperative recovery indicators were compared between the two groups,and questionnaires and position and postoperative nausea and vomiting were conducted on the day of discharge.RESULTS There were statistically significant differences in visual analogue scale pain scores at 12-96 hours postoperatively,the time of first ambulation postoperatively,and the length of postoperative hospital stay between the two groups(P<0.05).There were statistically significant differences in postoperative self-rating anxiety scale,self-rating depression scale,and satisfaction scores between the two groups(P<0.05).Further analysis using a binary logistic regression model found that the new narrative nursing model adopted postoperatively could improve patients’satisfaction with the work of nursing staff during their hospitalization.CONCLUSION The new narrative nursing model not only eliminated the negative emotions of patients,but also further promoted their postoperative recovery,and gained patients’trust and satisfaction with the nursing staff.
文摘Objective To determine the impact of planned preoperative phenazopyridine administration on operative times and costs compared with as-needed intravenous agent use during routine cystoscopy following minimally invasive hysterectomy for benign indications.Method This prospective cohort study examined patients who underwent laparoscopic or robotic-assisted total or supracervical hysterectomy for benign indications between January 27,2023 and March 11,2024,with one of our minimally invasive gynecologic surgeons at Stony Brook University Hospital.Patients were assigned to the non-phenazopyridine group or the phenazopyridine group.The time needed to visualize the ureteral jets during cystoscopy and the total surgery duration were recorded.A cost analysis was then performed.Results In total,106 patients were included,with 53 patients in each group.Compared with the non-phenazopyridine group,the phenazopyridine group had significantly shorter times from the start of cystoscopy to visualization of the first ureteral jet(31 s vs.42 s,p<0.05).However,there were no significant differences observed for visualization of the second jet,total jet time,or surgery duration.Two patients in the non-phenazopyridine group required the administration of intravenous agents intraoperatively.Routine phenazopyridine was found to be more cost-efficient when medication costs and operative times were examined.Conclusion Routine phenazopyridine use does not significantly shorten overall cystoscopy times,but it is the more cost-efficient option given increased rates of costly intravenous medication use in the non-phenazopyridine group.
文摘Objective:To investigate the preventive effect of targeted nursing interventions on deep vein thrombosis in patients with hemodialysis catheter indwelling.Methods:A prospective study was conducted involving patients who underwent hemodialysis catheter indwelling and were admitted between August 2023 and August 2025,totaling 108 cases.These patients were randomly divided into two groups using a random number table method,with 54 cases in each group.The control group received routine nursing interventions,while the observation group received targeted nursing interventions.The incidence of deep vein thrombosis and hemodynamic indicators were compared between the two groups.Results:The incidence of deep vein thrombosis in the observation group was lower than that in the control group(p<0.05).After two weeks of nursing,the hemodynamic indicators in the observation group were higher than those in the control group(p<0.05).Conclusion:Targeted nursing interventions can effectively prevent deep vein thrombosis and improve hemodynamics in patients with hemodialysis catheter indwelling,making them worthy of clinical promotion.

文摘This study investigates the variability in cancer diagnosis across different tissues and organs, with a focus on the role of diagnostic methods such as Hematoxylin and Eosin (H&E) staining and immunohistochemistry (IHC). The predominance of female breast cancer (30%) aligns with global trends, underscoring the need for robust diagnostic protocols, particularly in developing regions. Other prevalent cancers, including skin, stomach, and cervix uteri, reflect a mix of environmental, genetic, and infectious factors. The underrepresentation of gallbladder and thyroid cancers (<1%) suggests potential underdiagnosis or lower prevalence. Age distribution data indicate peak cancer incidence in individuals aged 31 - 45 years, with gender-specific cancers like breast and cervical cancer predominantly affecting females (63.4%). The analysis also highlights significant diagnostic gaps, as 61.2% of cases did not undergo IHC testing due to resource constraints, leading to potential biases in cancer prevalence and diagnostic accuracy. The study emphasizes the complementary role of IHC in confirming ambiguous H&E findings, with strong alignment observed when both methods were used. However, the absence of IHC in many cases limits the robustness of conclusions, suggesting the need for increased access to IHC testing. The findings advocate for integrating IHC into routine diagnostics, expanding diagnostic capabilities, and improving sample sizes to ensure more reliable and comprehensive cancer data.

文摘[Objective] This study aimed to reduce the content of cell wall materials in tobacco stems and improve their internal quality. [Method] Pectinase was used to decompose cell wall materials in tobacco stems, followed by determination of the contents of four cell wall materials, six routine chemical components, as well as aroma constituents. [Result] Pectinase could effectively reduce the contents of cell wall materials in tobacco stems, with the largest decrease of 6.84%; after pectinase treatment,the content of reducing sugar in tobacco stems increased obviously, and the contents of total sugar, potassium ion, chloride ion and total nitrogen increased to varying degrees, of which the contents of potassium ion and reducing sugar displayed upward trends with the increase of pectinase concentration. Pectinase treatment significantly increased the contents of Maillard reaction products, with the most increase of 67.2%;the contents of carotenoid degradation products, phenylalanine degradation products and neophytadiene all increased to varying extents, and the contents of both Maillard reaction products and phenylalanine degradation products revealed ascending trends with the increase of pectinase concentration. [Conclusion] Pectinase treatment can effectively decompose cell wall materials in tobacco stems, improve routine chemical constituents, and increase the contents of aroma constituents.

文摘With the improvement of seismic observation system, more and more observations indicate that earthquakes may cause seismic velocity change. However, the amplitude and spatial distribution of the velocity variation remains a controversial issue. Recent active source monitoring carried out adjacent to Wenchuan Fault Scientific Drilling （WFSD） revealed unambiguous coseismic velocity change associated with a local M8 5.5 earthquake. Here, we carry out forward modeling using two-dimensional spectral element method to further investigate the amplitude and spatial distribution of observed velocity change. The model is well constrained by results from seismic reflection and WFSD coring. Our model strongly suggests that the observed coseismic velocity change is localized within the fault zone with width of ~ 120 m rather than dynamic strong ground shaking. And a velocity decrease of -2.0 % within the fault zone is required to fit the observed travel time delay distribution, which coincides with rock mechanical experiment and theoretical modeling.
