The di-zhen (DZ) is an ancient type of acupuncture needle with a history dating back to more than 2000 years. Unlike modern acupuncture needles, the DZ is not inserted subcutaneously and is considered to be safe for common use, even at the bedside of terminally ill patients. In this case study, DZ application was selected and applied 14 times on a 92-year-old patient who had suffered severe oliguria along with administration of diuretics. Urine volume increased 12 out of 14 times following DZ treatment;however, the other two times it was ineffective. To investigate the reason and the differences in effective/ineffective DZ application, two internal conditions (effective vs ineffective) were compared by analyzing daily nursing reports (vital signs such as blood pressure, urine volume and body temperature) and weekly clinical data (including renal, liver and immune function, urea nitrogen, creatinine, ALT, AST, the ratio and number of leukocytes, erythrocytes). DZ application increased urine volume via a transient modification of the autonomic nervous system when internal homeostasis was maintained. Aging populations, who often have several diseases and medications, are rapidly increasing in developed countries. Therefore, the study and application of DZ may contribute to a reduction in medical costs, which have been rapidly and heavily expanding recently. 展开更多

The genetic polymorphism of SLA-DQA gene was investigated by PCR-RFLP. The effects of SLA.DQA gene on birth weight and 30-day-old weight were analyzed in 250 individuals of FI hybrid pig ( Heilongjiang wild boar x Beijing Black sow). The analysis revealed four poly- morphic loci in the SLA-DQA gene, but only the Pvu II locus in exon 2 of SLA-DQA gene ( BB genotype) greatly increased the 30-day-old weight of piglets. 展开更多

Malaria is uncontrolled burden in the world till now.Despite of different efforts to develop antimalarial drug for decades,any anti-malarial drug can able to eradicate completely till now.Many anti-malarial substances are practically ineffectual because of their physicochemical limitations,cytotoxicity,chemical instability and degradation,and limited activities against intracellular parasites.Taking into consideration,the amount of research is going to conduct in the field of nanoparticle based drug delivery systems,lead to new ways of improving the treatment of infectious diseases.The study has focused on the progress and advancement of research on nanotechnology based drug delivery to eradicate the malaria.We like to focus the efficacy of nanotechnology based drug application for the opening out of novel chemotherapeutics in laboratory research,which may show the way to better use with age-old antimalarial drug and may draw the attention of pharmaceutical industries for the improvement and designing of effective anti-malarial drugs in future. 展开更多

The purpose was to examine and compare the psychometric properties of a Mexican Spanish version of the WHOQOL-OLD module. The instrument was applied to 285 individuals aged over 60 years (mean = 69.26, SD = 6.52). All participants completed a demographic data sheet, the WHOQOL-OLD, the Beck Depression Inventory (BDI), and the Geriatric Depression Scale (GDS);182 of the 285 participants also completed a quality of life questionnaire for diabetic patients (DQOL). Acceptable levels of reliability were found, with Cronbach’s alpha values between 0.70 and 0.90 for overall quality of life and all domains except for autonomy, where the alpha value was low. The exploratory factor analysis carried out to examine the construct validity of the instrument yielded six domains: sensory abilities, autonomy, past/present/future activities, social participation, death and dying, and intimacy (explained variance of 62.95%). The mean overall quality of life score was 94.86 (SD = 13.68, range 50 to 120). The WHOQOL-OLD module showed criterion validity and concurrent validity with respect to the BDI (r = -0.516, p = 0.034), the GDS (r = -0.336, p = 0.002), and the DQOL (n = 182, r = 0.159, p = 0.032). Discriminant validity was also confirmed with respect to self-perceived health (t = 2.701, d.f. = 225, p = 0.007) and education (F(3, 280) = 9.015, p p > 0.05). We conclude that the Mexican Spanish version of the WHOQOL-OLD module has adequate psychometric properties. 展开更多

This study was conducted to investigate the effects of different concentrations ofβ-mercaptoethanol on the development ability of oocytes in Dorper sheep at the age of 6 weeks.In this study,6 Dorper sheep of 6 weeks old were chosen to induce oocyte collection in vivo by gonadotropin,and A and B grade cumulus oocyte complexes were obtained(COCs)with different concentrations of(0,50,70 and 100μmol/L)ofβ-mercaptoethanol in the mature liquid.The cleavage rate and blastocyst rate were counted after matured oocytes and capacitated sperm were co-incubated and fertilized eggs were cultivated.The results showed that compared with the cleavage rate(59.13%)and the blastocyst rate(12.17%)of the control group,the cleavage rates(60.87%,63.48%and 65.22%)and blastocyst rates(14.78%,17.39%and 21.74%)of the test groups I,II and III were higher(P>0.05),and the order was test group III>test group II>test group I>control group.The cleavage rate and blastocyst rate of the 100μmol/Lβ-mercaptoethanol group increased by 6.09 percentage points and 9.57 percentage points,respectively.It indicated that the addition of a certain amount ofβ-mercaptoethanol in the mature liquid could improve the developmental ability of oocytes and the quality of fertilized eggs of the 6-week-old Doper sheep.When theβ-mercaptoethanol concentration was within 100μmol/L,the cleavage rate and the blastocyst rate of oocytes were on the rise.The optimal concentration ofβ-mercaptoethanol in the mature liquid still needs further study. 展开更多

Female genital mutilation (FGM) is still a topical practice in several African regions or countries. They constitute a violation of human rights, in particular because of their harmful consequences for the health of the people who suffer them and are the source of various complications. We report a case of FGM complications in the form of total coalescence of the labia majora with a small hole from which urine flows permanently. The management was a disinfubilation with suturing of the edges and urethral reimplantation and the evolution was favorable with complete healing after two (2) weeks. 展开更多

INTRODUCTION Although the differential diagnosis for chest wall masses is broad, the vast majority are abscesses, lipomas, or sebaceous cysts. Post-operative chest wall masses can also include infection, hematoma, seroma, cancer recurrence, metastasis, and lung hernia. Bedside ultrasound has been well documented to be beneficial in the differentiation of superficial pathology. Pleurocutaneous fistula is a pathologic communication between the pleural space and subcutaneous tissues of the chest wall. Pleurocutaneous fistula is a rare complication of tube thoracostomy, video-assisted thoracic surgery (VATS) procedures, and various pulmonary infections. 展开更多
