Objective To evaluate the surgical technique and clinical application of retroperitoneal laparoscopic pyelolithotomy and ureterolithotomy with no suture of the incision. Methods Twenty-five patients who had upper urinary tract calculi with the course from 10 months to 6 years were enrolled.The size of the calculi was 1.2 to 3.1 cm in diameter.ESWL was ineffecative in 14 of the patients and ureteroscopic lithotomy failed in 2 of them.Then the 25 patients underwent retroperitoneal laparoscopic pyelolithotomy and ureterolithotomy.Details of the procedure were presented. Results All the operations were successful in the 25 patients. The operations took 60 to 190 min with a mean time of 105 min.All the patients fully recovered with no complication observed during the 9～12 months' follow-up. Conclusions Retroperitoneal laparoscopy surgery with no suture of the incision has advantages of minimal invasive,safe,effective and rapid postoperative rehabilitation.The surgical procedure has a good prospect in the urologic clinical practice.

Objective:To compare the changing trends and differences of bed numbers,doctor numbers and medical service utilization in the US.and China so as to provide polity implication for the health care reform in China from the supply side.Methods:The data of beds,doctors,hospitalization and outpatient service utilization from the website of OECD and CDC of the United States as well as Chinese Statistical Yearbook of Health and Family Planning were used to describe the trends.Results:The beds per 1000 people in China had exceeded that of the US,while the doctors per 1 000 people in China was less than the US.Both the two countries had yearly increasing trend of outpatient visits.However,the hospitalization was decreasing in the US,while the growth rate of hospitalization was even higher than the outpatient visits in China.Conclusion:The decrease of bed amount and the increase of outpatient amount were the main changing trend of medical resources and service utilization in the US.The imbalanced structure of medical resource supply in China resulted the overuse of hospitalization services.In the supply side reform of medical reform in China,it suggested to promote the cooperation of medical insurance,drug and health care,adjusted the reform thought from resource amount into the promotion of service quality,changed the health management system from disease centered into health centered.

Objective: To study the influence of the dietary n 3 and n 6 long chain polyunsaturated fatty acids with 20 or 22 carbon atoms (LCPFA) intake on the LCPFA status, growth and development. [WT5HZ]Methods: [WT5BZ]32 preterm infants were divided into three groups which were fed respectively: A, breast milk (n=11); B, a conventional formula lacking LCP (n=10); C, docosahexaenoic acid (DHA) and arachidonic acid (AA) enriched formula (n=11). The length, weight and head circumference of preterm infants were measured at 1 mo?7 d, 2 mo?7 d, 3 mo?7 d. LCPFA status of plasma and RBC were analyzed at birth and at the weight of (2.5?0.10) kg when group C was stopped being fed enriched formula. The experiment period was three months. [WT5HZ]Results: [WT5BZ]At 3 mo?7 d, head circumference of group B was significantly lower than that of group A and group C (P

Objective: To study the effects of long chain PUFA, AA and/or DHA on the fatty acid composition, growth and development of the newborn rats hippocampal neurons in culture. Methods: The primary culture of the hippocampal neurons was carried out in vitro by using serum free medium and supplementing 4 ? mol/L AA, DHA, or AA and DHA, of which the total concentration were 4 ?mol/L, the ratios of AA∶DHA from 1∶2 to 16∶1, in medium. The hippocampal neuronal fatty acid composition was analyzed by gas chromatogram, and the neuronal size and length of hippocampal neurite were measured by image analysis. Results: There were significant positive correlations between the ratios AA∶DHA in medium and the AA percentage and the ratios AA∶DHA in hippocampal neurons. The soma area? body maximum? minimum diameter and process length of hippocampal neurons in the group, which the total concentration of AA and DHA was 4 ?mol/L, and the ratio AA∶DHA in medium was 2∶1 or 4∶1,were higher significantly than other groups and groups with other ratios of AA∶DHA. Conclusion: AA and DHA could promote the growth and development of hippocampal neurons in culture..

Objective To evaluate the alteration of CD4+ regulatory T cells in peripheral blood from patients with ankylosing spondylitis(AS). Methods Seventy-eight AS patients and 50 healthy individuals were included in this study. The proportion of CD4+CD25+CD127lo/- T cell population in CD4+ T cells as well as that cytotoxic T lymphocytes(CTL) and NK cells in lymphocytes was evaluated by flow cytometry. Serum TGF-β and TNF-α were measured by ELISA. The inhibitory function of CD4+CD25+ regulatory T cells was measured by mixed lymphocyte culture. Results The population of CD4+CD25+CD127lo/- T cells in peripheral blood of AS patients accounted for (4.36±1.21)% of CD4+ T lymphocytes, which was significantly lower than that in healthy individuals (P<0.05). The CD4+CD25+CD127lo/- T cells population in AS patients was positively correlated with TGF-β level, but negatively with TNF-α. Compared with healthy individuals, the function of CD4+CD25+ regulatory T cells in the inhibition of alloreactive T cells was lower in AS patients, which was related to the decreased secretion of TGF-β. Conclusion The CD4+ regulatory T cells in peripheral blood of AS patients are significantly decreased and its function is defective, which leads to immune regulatory dysfunction in vivo. It may be one of immune pathogenesis mechanisms of AS.

Objective To study the clinical characteristics,treatment and prognosis of neonatal VACTERL association.Method The clinical data of newborns diagnosed with VACTERL association from January 2010 to December 2015 were collected and retrospectively analyzed.Result A total of 33 patients diagnosed with VACTERL association were included,including 23 males and 10 females.Among them,17 cases were term infants,15 cases premature infants and 1 case of overdue birth,with an admission age of 1 to 24 days.The most common deformities were cardiac anomalies (C) in 27 cases (81.8％),followed by anal atresia/anorectal malformation (A) in 25 cases (75.8％),renal deformity (R) in 24 cases (72.7％),limb abnormalities (L) in 20 cases (60.6％),Tracheoesophageal fistula (TEF) in 8 cases (24.2％) and vertebral abnormalities (V) in 3 cases (9.1％).11 cases (33.3％) had other deformities.Among these 33 patients,24 cases had 3 types of malformations and 9 cases had 4 types of malformations.The most common combination was ACR (n =8).20 patients had no abnormalites on chromosome karyotype test including 2 patients had normal gene microarray results.16 patients received surgical treatment during neonatal period and 13 of them recovered and discharged.Among the other 17 cases received no surgery,only 1 patient improved and discharged.A telephone follow-up was proceeded in 14 discharged cases at 1 year old.Among them,13 cases had good prognosis,however,the remaining one was dead.Conclusion VACTERL association is a rare non-random combination of multiple malformations.The early discovery and appropriately treatment after diagnosis will improve the prognosis and prevent death.Doctors should reinforce the ability to detect various types of deformities and examine the chromosome and gene properly.

Objective To evaluate the effects of soy isoflavones on bone density (BMD) in women in randomized clinical trials by meta-analysis. Method We searched the databases the Medline, Pubmed, and CNKI from January 1990 to October 2007 using the keywords, phytoestrogen, isoflavone, soy, genistein in combination with bone. We only included the studies of randomized clinical trial, in which the data of BMDs at lumbar spine, total hip or femoral neck prior to and post isoflavone intervention or their relevant changes and their standard deviation or 95% CI in women were provided. Results Sixteen papers (1304 women, 91% postmenopausal) were included and a mean daily dose of 73 mg supplemental soy isoflavones resulted in weighted mean (%)(95%CI) difference in yearly BMD changes of 18.3 (2.0%,CI 6.0~30.6) and 3.3(0.40%,CI 0.5~6.1) mg/cm2 at the lumber spine and total hip, respectively. Subgroup analyses showed that the effects were more pronounced in those with the isoflavone dose ≥80 mg/d than those of
