Objective To study the impact of capitation payment on obstetric indicators for the maternity insurance of urban workers in Yinchuan city.Methods Collection of indicators on lying-in women hospitalized at the obstetrics departments of designated hospitals in Yinchuan,in the period of 2011 to 2012 when the capitation payment was put in place.Such indicators include the percentage of uterine-incision delivery,diagnostics and therapeutic expenses,drug expenses,and average days of stay,along with mortality of pregnant and lying-in women and that of newborns,which are used as indicators to measure quality of care.Results The capitation payment policy has witnessed drops in the percentage of uterine-incision delivery,cost per inpatient,drug expenses per inpatient and average days of stay among urban workers covered by the insurance.The drops amount to 10％ for cost per inpatient and 45％ for drug expenses per inpatient.The differences found in pregnant and lying-in women are not statistically significant.Conclusion Capitation payment is conducive to dropping the percentage of uterine-incision delivery and medical expenses,and saving medical insurance payment,for the sake of optimal use of healthcare resources.

SUMMARY Behcet’sdisease(BD)isachronicvascularinflammatorydiseaseofunknowncauses.Itis called intestinal BD,when digestive tract is involved.To investigate small bowel feature of intestinal BD, we now report 5 intestinal BD cases undergone capsule endoscopy from December,2010 to April,2014 in Peking University People’s Hospital.General information,clinical feature and endoscopic feature were presented,and literatures were reviewed.There were 3 male and 2 female patients.Age range was from 23 to 55 years old (median age 40 years old).Disease course was from 3 days to 28 years (median course 9 years).4 patients were diagnosed as systemic BD,and the rest independent intestinal BD.4 systemic BD patients all presented as recurrent oral aphthous as initial symptom and had history of vulvar ulcer and skin lesion.They all had gastrointestinal symptoms,including retrosternal pain (2 cases),he-matochezia (3 cases),diarrhea (3 cases)and abdominal pain (2 cases).1 patient had a history of fis-tula of ileocecal junction and underwent caecectomy.5 patients all underwent whole digestive tract exami-nation by endoscopy,including gastroscopy,colonoscopy and capsule endoscopy.Except of 1 normal re-sult of colonoscopy,all endoscopy results revealed lesions.Capsule endoscopy results of all patients were abnormal.Types of small intestinal lesion were various,including ulceration,erosion,protrusion and vasculopathy.All digestive tract can be involved in BD patients.Capsule endoscopy can evaluate lesions throughout whole digestive tract,especially in small intestine.As a consequence,it is helpful to explain gastrointestinal symptom,increase early diagnostic rate.Intestinal BD (IBD)mainly involves small bow-el,and ileum is the major involved segment,not only limited in ileocecum.The updated perspective of IBD lesion distribution will contribute to differential diagnosis between IBD and Crohn’s disease.This is the first time to report capsule endoscopic feature of BD patients in China.

Objective The aims of this study were to investigate the expression of microRNA-30a(miR-30a)in human bladder cancer cell lines and their effects on the proliferation,apoptosis and migration of human bladder cancer cells.Methods The expression levels of miR-30a in bladder cancer cell lines(5637 and T24)and bladder epithelial immortalized cells(SV-HUC-1)were detected by real-time quantitative PCR(qRT-PCR).The expression of miR-30a was up-regulated or down-regulated by T24 cells transfected with miR-30a mimic or 5637 cells transfected with miR-30a inhibitors and controls using NC mimic or NC inhibitor.The effects of miR-30a expression on the proliferation,apoptosis and invasion of bladder cancer cells were investigated by flow cytometry,MTT and Transwell assays.Results The expression level of miR-30a in two bladder cancer T24 and 5637 cell lines was significantly lower than that in normal bladder SV-HUC-1 cell line(P<0.05),and the expression level of miR-30a was lower in the high degree of malignancy in bladder cancer T24 cells than that in malignant degree of relatively low 5637 cells.After 72h transfection,the values of optical density(OD)in the miR-30a mimic group(0.83±0.09)was significantly lower than that in NC mimic group(1.21±0.12)in T24 cells(P<0.01).The OD values of miR-30a inhibitor group(1.28±0.14)was significantly lower than that in the NC inhibitor group(1.09±0.14)in 5637 cells(P<0.01).The apoptotic rate of miR-30a mimic group in T24 cells(21.27±2.42)% was significantly higher than that in the NC mimic group(10.61±1.29)%(P<0.01).The apoptotic rate of the miR-30a inhibitor group in 5637 cells(6.78±2.57)% was significantly lower than that in the NC mimic group(13.42±1.40)%(P<0.01).The number of transmembrane cells in miR-30a mimic group in T24 cells(183.57±16.61)was significantly lower than that in NC mimic group(465.80±9.20)(P<0.01).The number of transmembrane cells in the miR-30a inhibitor group in 5637 cells(581.25±11.02)was significantly lower than that in NC mimic group(397.13±7.57)(P<0.01).Conclusion Up-regulation of miR-30a can inhibit the proliferation of bladder cancer cells,promote cell apoptosis and reduce the ability of migration and invasion in bladder cancer cells.The low expression of miR-30a in bladder cancer cells may be related to the development and metastasis in bladder cancer.

Objective To describe the sonographic features of abdominal wall endometriosis(AWE).Methods 105 consecutive women with proven pathological endometriosis of the abdominal wall were retrospectively recruited.The clinical data and the result of the sonographic examinations were reviewed and described.The AWE lesions were divided into ＜3 cm and ≥3 cm groups according to their maximum diameter.Results The sonographic feature of AWE includes irregular hypoechoic nodules with ill-defined margins,anechoic and hyperechoic ring maybe exist.In color Doppler,most of them showed few internal vascularity.Compared with≥3 cm group,＜3 cm group nodules manifested as shorter latent period,with more superficial location,round or oval shape,peripheral hyperechoic ring and none or few vascularity were more common.As for ≥3 cm group nodules manifested as longer latent period,with deeper location,irregular shape,abundant of vascularity were more common.Conclusions Specific diagnosis of AWE can be made by using high frequency sonography combined with clinical features.More accurate information can be provided by judging the size,range and infiltrative depth.

Objective To investigate the effects of simethicone on the quality of video capsule endoscopy (VCE) examination.Methods A prospective study was performed in 90 patients received VCE examination from February 2010 to October 2014.The randomized table was set according to different dosage of simethicone the patients received,by which patients were divided into three groups.Group 1 (35 cases) received 15 mL simethicone,group 2 (30 cases) received 30 mL simethicone and control group (25 cases) received no simethicone.The small intestinal visualization quality of VCE was scored by segments.Segment A was proximal small intestine (one hour after VCE passing pylorus).Segment B was distal small intestine (one hour before VCE passing ileocecal valve).Segment A and B were scored according to the air bubbles and degree of cleanliness.Gastric transit time,small bowel transit time and VCE completion rate were recorded.Student's t test,Mann Whitney rank sum test and chi square test were performed for statistical analysis.Results The average scores of segment A of group 1,group 2 and control group were 0.58,0.33 and 1.67,respectively,and the average socres of segment B were 0.25,0.00 and 1.17,respectively.The lesion detection rates of group 1,group 2 and control group were 68.6％ (24/35),80.0％ (24/30) and 52.0％ (13/25),respectively,and the differences was statistically significant (x2 =8.238,P=0.016).The detection rate of group 2 was significantly higher than those of group 1 and control group (x2 =7.354 and 9.349,P=0.034 and 0.005).The detection rates of small intestinal erosion of group 1,group 2 and control group were 22.9％ (8/35),70.0％ (21/30) and 32.0％ (8/25),respectively,and the differences was statistically significant (x2=8.714,P=0.013).The detection rate of group 2 was significantly higher than those of group 1 and control group (x2 =10.600 and 7.380,P=0.005 and 0.025).There was no statistically significant difference in the detection rates of ulcer,vascular malformation and protrusion among the three groups (all P＞0.05).The detection rates of lesions＜0.5 cm of group 1,group 2 and control group were 37.1％ (13/35),66.7％ (20/30) and 32.0％ (8/25),respectively,and the differences was statistically significant (x2 =8.242,P=0.016).The detection rate of group 2 was significantly higher than those of group 1 and control group (x2 =9.250 and 7.842,P =0.011 and 0.017).Conclusion Oral adminstration of 30 mL simethicone could obviously decrease air bubbles in small intestine,and increase lesion detection rate of VCE.

To study the effect of Gegen Qinlian decoction and its major effective components on five hepatic microsomal CYP450 isozymes in rats. The in vitro hepatic microsomal incubation technique was used to co-culture Gegen Qinlian decoction and its major effective components together with each probe substrate. HPLC-MS/MS was used to establish the analytical method for metabolites of the five isoform probe substrates of CYP450 isozymes, detect the linearity among micoromal protein concentration, incubation time and metabolite formation amount. And HPLC-MS/MS was applied to determine the formation rate (V) of corresponding metabolites (acetaminophen, 4-OH-chlorzoxazone, dextrophan, 6-OH-chlorzoxazone and 6β-hydroxytestosterone) specific probe substrates of the five isoform probe substrates of CYP450 isozymes (phenacetin, polbutamide, dextromethorphan, chlorzoxazone, testosterone), in order to determine the activity of each isozyme. The result showed good linearity among acetaminophen, 4-OH-tolbutamide, dextrophan, 6-OH-chlorzoxazone and 6β-hydroxytestosterone, satisfactory precision, stability and average recovery, suggesting the method was feasible. The optimized in vitro microsomal incubation conditions conformed to the requirements in the guideline of drug-drug interaction. Gegen Qinlian decoction showed different degrees of inhibitor effect on 5 CYP450 isoforms (CYP1A2, CYP2C11, CYP2D2, CYP2E1, CYP3A1/2). Its major effective component berberine could inhibit each CYP450 isoform at high concentrations (except for CYP1A2, CYP3A1/2).
