Objective To analyze the effect of duodenal endoscopy in the treatment of common bile duct stones.Methods 70 patients with common bile duct stones in our hospital were randomly divided into the observation group (35 cases) and the control group (35 cases) by the random number table method.All the patients were treated with the treatment of duodenal endoscopy, and the perioperative clinical nursing, the control group was nursed by conventional nursing,the observation group was nursed by quality care.The surgical effect of the two groups was evaluated,the incidence of postoperative complications was analyzed,and the nursing satisfaction of the two groups was investigated.Results The average operation time, postoperative anal exhaust time, out of bed activity time and hospitalization time of the observation group were shorter than the control group (t=6.535,7.884,10.228,12.192, all P<0.05),and average intraoperative bleeding volume was less than that of the control group (t=5.984,P<0.05).The total incidence rate of biliary tract infection,bleeding,bile leakage,bile leakage,bile duct stricture and complication was 8.58%in the observation group,which was lower than 22.85%in the control group (χ2 =7.464, P<0.05).In the observation group,the patients′satisfaction to the comprehensive nursing,humanized nursing and nursing quality were 94.29%,91.43% and 94.29%, which in the control group were 80.00%,77.14% and 77.14%,the differences between the two group were statistically significant (χ2 =7.435,8.245,7.446, all P<0.05).Conclusion High quality nursing care to patients with common bile duct stones who received endoscopic therapy perioperatively is helpful to improve the effect of operation,prevent postoperative complications and improve the patients'satisfaction.

BACKGROUND: At present, the clinical application of amplified neural stem cells in the treatment of nervous system diseases is stil in exploratory stage. OBJECTIVE: To investigate efficacy and safety of neural stem cel transplantation for the treatment of Parkinson’s disease. METHODS: The embryonic brain tissues aged 12 weeks were obtained for proliferation in vitro, then the brain tissues (5×106-2×107) were prepared into the 4-6 mL suspension. The suspension was injected into 30 cases of Parkinson’s disease through lumbar puncture and carotid injection, once a week, continuously for 3 weeks. Unified Parkinson’s disease rating scale, Hoehn-Yahr scale and Schwab & England Activities of Daily Living Scale scoring were performed prior to and after transplantation. Blood and urine routine, liver function, renal function and adverse reactions were detected and evaluated prior to and after transplantation. RESUTLS AND CONCLUSION: The 12-week-old embryos cultured neural stem cells could be stably amplified in vitro with the capacities of differentiation into neurons, astrocytes and oligodendrocytes. The fol ow-up results showed that neural stem cel transplantation could effectively control the pathological process of Parkinson’s disease, restore the damaged brain function, and improve the patient’s neurological function without significant complications. It is feasible and effective to use the in vitro long-term amplified human neural stem cel transplantation in the treatment of Parkinson’s disease.

Methylenetetrahydrofolate reductase (MTHFR) is an enzyme that plays a critical role in the folate and homocysteine metabolism.MTHFR mutation leads to decreased 5-methylenetetrahydrofolate synthesis.Consequently, it influences the conversion of homocysteine to methionine causing homocysteine accumulation.Homocysteine has been considered as an independent risk factor for a variety of diseases such as cardiovascular diseases , neurological and psychiatric disorders as well as cancers .The study on the correlation between methylenetetrahydrofolate reductase gene polymorphisms and diseases and the discovery of its clinical value is getting more and more attention.
