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.

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.

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.

Objective To study the effects of Tongxinluo capsule and Shen Mai injection in treatment of patients with acute myocardial infarction and its effects on level of left ventricular ejection fraction (LVEF),high sensitive C-reactive protein (hs-CRP),natriuretic peptide (BNP) and QT in acute decompensated heart failure ( QTcd) .Methods 82 patients with acute decompensated heart failure were selected in our hospital from May 2014 to April 2015, those patiens were divided into observation group and control group according to the method of lottery, 41 cases each group.The control group was treated with basic treatment and Huangxin injection, and the obsevation group was treated with Tongxinluo capsule on the basis of the control group.The changes of blood pressure, heart rate, LVEF, hs-CRP, BNP and QTcd were compared between the two groups before and after treatment. Results After treatment, the total effective rate of the observation group was significantly higher than the control group [92.68% (38/41) vs 60.97%(25/41)](P<0.05).The heart rate of the observation group was significantly lower than the control group (P<0.05), but the blood pressure level of the two groups had no significant difference.The levels of BNP, hs-CRP and QTcd in the observation group were significantly higher than the control group [(45.98 ±4.57)% vs(39.07 ±3.12)%](P<0.05) L, BNP, hs-CRP and QTcd were significantly lower than the control group [(2432.12 ± 114.32)ng/L,(17.32 ±1.87) mg/L, (34.76 ±3.02) ms vs (3565.87 ±174.76) ng/L, (14.08 ±1.23) mg/L,(38.45 ±3.86)].Adverse reactions were not observed in the observation group and the control group.Conclusion Tongxinluo capsule combined with Shen Mai injection can effectively increase the left ventricular ejection fraction and reduce hs-CRP, BNP and QTcd in patients with acute decompensated heart failure.The clinical curative effect is good and the safety is high.

Objective:To study on regional differences of technical efficiency under medical and health system in China, and analyze on the influence factors of technical efficiency. Methods: Based on the provincial panel data from 2002 to 2011, the stochastic frontier production function of healthcare system was established for empirical analysis. Results and Conclusion: Overall, the average technical efficiency of medical and health system in China presented an increasing tendency, however, a significant difference was found in regional efficiency. The non-efficiency of medical and health system in different areas could be reduced by the proportion of tertiary hospitals in all medical institutions, the ratio of profit-making medical institutions in all medical institutions and the population density;while the influences of highway density and per capital education year on technical efficiency in different areas are different.

Objective To investigate the effect of dopamine receptor in intestinal mucosal barrier function after brain injury in rats.Methods Twenty-four rats were allocated to control group,brain injury group,dopamine receptor group,and dopamine antagonist group according to the random number table,with 6 rats per group.Feeney' s weight-drop model was introduced to generate rat models of brain injury.Intestinal mucosal specimens were harvested at postoperative 7 days to evaluate intestinal mucosal morphology by HE staining,expressions of dopamine receptor D1 (DRD1) and dopamine receptor D2 (DRD2) by immunohistochemistry,and mRNA and protein expressions of DRD1 and DRD2 by real-time PCR and Western blot.Meantime,urinary samples were collected to measure lactulose to mannitol ratio (L/M) by high performance liquid chromatography (HPLC).Results Intestinal villus integrity was disrupted in brain injury group and dopamine receptor group when compared to control group,but it remained relatively intact in dopamine antagonist group.Ratio of L/M in brain injury group and dopamine receptor group was similar (0.192 ± 0.080 vs 0.183 ± 0.090,P ＞ 0.05),far higher than 0.037 ± 0.008 in control group (P ＜0.01),but it was reversed in dopamine antagonist group (0.071 ± 0.008,P ＜ 0.01).Real-time PCR showed DRD1 and DRD2 mRNAs expressed in brain injury group and dopamine receptor group were similar (0.764 ± 0.074 vs 0.718 ± 0.065,0.439 ± 0.051 vs 0.408 ± 0.090,P ＞ 0.05),far higher than 0.189 ± 0.008 and 0.076 ± 0.011 in control group (P ＜ 0.01),but both lowered in dopamine antagonist group (0.386 ± 0.071,0.270 ± 0.092,P ＜ 0.01).estern blot analysis showed DRD1 and DRD2 proteins in brain injury group and dopamine receptor group were similar,but both were far higher when compared to control group (P ＜ 0.01).Conclusion Impaired intestinal mucosal barrier may be relate to the up-regulated dopamine receptor in intestinal mucosa after brain injury in rats.

The occurrence and development of tumor depends not only on the tumor itself,but also depends on the soil survival of tumor cells,that is the tumor microenvironment.Studies confirm that the changes of blood vessels and hypoxic of tumor microenvironment maintain the stemness of cancer stem cell,and further strengthen the ability of tumor invasion and metastasis.Studying the molecular mechanism of tumor development from angiogenesis and lack of oxygen can provide new ideas for the clinical targeted therapy.
