Objective To determine the prevalence of female urinary incontinence among Chinese people in different areas. Methods A sampling survey of urinary incontinence was conducted on 668 female adults in a Beijing community,the Uygur region and a residential district inside the First Hospital of Peking University with questionnaire. Results The prevalence of female urinary incontinence was 46.5%(94/202) in the Beijing community,43.8%(134/306) in the Uygur Region and 40.6%(58/143) in the residential district inside the First Hospital of Peking University.The ratios of those who consulted with doctors to the separate surveyed population were 24.5%(23/94),29.1%(39/134),13.8%(8/58),respectively. Conclusions The prevalence of female urinary incontinence is similar in different population.Only a few of these women went to doctors,especially among the hospital staff and workers.

Objective To investigate the alterations of serological endothelin(ET) in patients with kawasaki disease(KD) and its relation with coronary dilatation(CAD).Methods Serological ET were measured in 50 cases of patients with KD in acute phase as well as subacute phase; 30 cases of patients with acute febrile infection(IC) in infective phases and 30 healthy children(HC).Results 1.ET in subacute phase significantly increased than that in acute phase.2.In both acute and subacute phases of KD, ET significantly elevated higher than that in HC; and ET in subacute phase significantly elevated than that of IC. 3. Fifty-four percentage patients with KD were complicated with CAD. For CAD subgroup, ET had no difference with CAD subgroup in subacute phase.Conclusion ET has still increases in subacute of KD,which indicates the relation with coronary artery lesion.

Objective To explore the effect and safety of transcranial approach for spheno-orhital meningioma. Design Retro- spective case series. Participants Thirty-two patients being operated with transcranial approach. Twenty-four cases were meningothelial meningiomas, 3 cases were fibrous meningiomas, 1 case was psammomatous meningioma, 2 cases were atypital meningiomas, 2 case were malignant meningiomas. Methods All patients underwent frontal-temporal craniotomy, the involved sphenoid wing bone and peri- orbit were removed to prevent recurrence. The superior orbital fissure and optic canal were decompressed, the dural and periorbital de- feet were repaired by autogenous temporal fascia or artificial dura. Main Outcome Measures Preoperative and postoperative exoph- thalmus and eyeball movement, the extent of tumor resection, the ratio of recurrence. Results The extent of tumor resection: 8 cases were Simpson gradeⅡ, 20 cases Simpson gradeⅢ, 4 cases Simpson grade IV. After surgery, proptosis were improved in all patients, ophthalmoplegia was found in 6 eases. There was no operation-related death or other significant complication. Tumor recurred in 6 cas- es. Conclusions Adequate exposure of the tumor and bony decompression of the cranial nerves can result from transcranial approach, all the involved bone should be removed in order to prevent recurrence. This approach is relatively safe and the ptoptosis are improved significantly. Complete surgical resection is difficult because of the involvement of the orbital apex, superior orbital fissure and cav- ernous sinus.

Objective To-identify the factors associated with radiation-induced liver disease (RILD) and to describe the probability of RILD using the Lyman normal tissue complication(NTCP) model for primary liver carcinoma(PLC) treated with hypofractionated conformal therapy (CRT).Methods A total of 109 PLC patients treated with hypofractionated CRT were prospectively followed according to the Child-Pugh classification for liver cirrhosis,93 patients in class A and 16 in class B.The mean dose of radi- ation to the isocenter was (53.5?5.5) Gy,fractions of (4.8?0.5) Gy,with interfraction interval of 48 hours and irradiation 3 times per week.Maximal likelihood analysis yielded the best estimates of parameters of the Lyman NTCP model for all patients;Child-Pugh A and Child-Pugh B patients,respectively.Results Of all the patients,17 developed RILD (17/109),8 in Child-Pugh A(8/93 ) and 9 in Child-Pugh B(9/ 16).By multivariate analysis,only the Child-Pugh Grade of liver cirrhosis was the independent factor (P= 0.000) associated with the developing of RILD.The best estimates of the NTCP parameters for all 109 pa- tients were n=1.1,m=0.35 and TD_(50) (1)=38.5 Gy.The n,m,TD_(50) (1) estimated from patients with Child-Pugh A was 1.1,0.28,40.5 Gy,respectively,compared with 0.7,0.43,23 Gy respectively,for patients with Child-Pugh B.Conclusions Primary liver cancer patients who possess Child-Pugh B cirrho- sis would present a significantly greater susceptibility to RILD after hypofractionated CRT than patients with Child-Pugh A cirrhosis.The predominant risk factor for developing RILD is the severity of hepatic cirrhosis in the liver of PLC patients.

Its research will further promote and perfect TCM information standard system. We have adhered to the connection among ancient TCM classification framework, modern TCM and western medicine classification framework. Exploration on framework construction of ancient Chinese medical literature clinical terminology classification standardization was based on previous work of Chinese medicine clinical terminology classification and code standard, reference frame structure of SNOMED CT, research findings of classification standard framework of Chinese medicine clinical terms, andQian Jin Fang.

Objective To explore the clinical value and safety of early enteral nutrition support in patients after liver transplantation.Methods We retrospectively analyzed the clinical data of 86 cases who used early enteral nutrition support therapy after liver transplantation between January 2008and October 2011.All of patients were uproot the gastric tube at the first day after the operation,and gradual to the normal diet.The patients who used parenteral nutrition support therapy were as the control group(n＝112).Then we compared the data of patients in the two groups.Results The early enteral nutrition is more useful to the patients after liver transplantation than intravenous nutrition [In the seventh day after the operation,the control group's ALT was (45.2 ± 12.9) U/L,AST was (40.2±9.4) U/L,ALBwas (35.6±2.5) g/L,P＜0.05].The early enteral nutrition also can decrease hospital stay and hospital costs [(14.2±3.4) d,P＜0.05].Conclusion The early enteral nutrition is useful and safe to the patients after liver transplantation.

ObjectiveTo share the experience of arterial plasty and reconstruction of variant arteries in living donor liver transplantation. MethodsFrom September 2006 to May 2010, 73 living donor liver grafts (64 cases using the right lobe,9 cases using left lobe) were used in patients with end-stage liver disease. The hepatic arteries were evaluated preoperatively with computed tomography and magnetic resonance angiography. Back-table arterial plasty was performed under a microscope or a loupe according to arterial variation. We described technical points based on anatomic variations. There were 13 (17. 8 ％) liver grafts with anatomic hepatic arterial variations and all of these cases were subjected to back-table reconstruction with interrupted 8-0 or 9-0 nonabsorbable nylon monofilament sutures according to the diameter of artery. ResultsIn 3 cases, the associate right hepatic arteries that were arisen from superior esenteric arteris (SMA) were reconstructed to cystic arteries. In 2 cases with the associate right hepatic arteries arisen from the abdominal trunk, the right hepatic arteries and associate right hepatic arteries of donors were anastomosed with right hepatic arteries and left hepatic arteries in recipients respectively. In 2 donors, hepatic arteries had branches, which were reconstructed. All of the arterial plasty were conducted on a back table. No arterial thrombosis was found during a postoperative follow-up period of 6 months. ConclusionLive donor liver transplantation using the right lobe with hepatic artery variation can be performed safely, but there is a potential operative risk of severe complication after transplantation. Tominimize operative difficulties and complications, back-table reconstruction should be applied and proper treatment is given according to individual situations to ensure a safe and satisfactory outcome

Hydrolytic amino acids were extracted by acid hydrolysis method, then derivatized with phenyl isothiocyanate (PITC). And the samples were analysed by HPLC on an Ultimate Prime C18 (4.6 mm x 250 mm, 5 microm) column with gradient elution of 0.1 mol x L(-1) sodium acetate buffer solution (adjusted to pH 6. 5)-acetonitrile (93:7) (A) and acetonitrile-water (8:2) (B) at a flow rate of 1.0 mL x min(-1). Column temperature was 40 degrees C and the detected wavelength was 254 nm. Amino acids derivative solution remained stable in 36 hours. The response was linear for 16 amino acids with a correlation coefficient r > 0.999 5. The average recoveries were 98.01% -101.8%. The method is reliable with good accuracy and repeatability, which is useful for the determination of amino acids in Galli Gigerii Endothelium Corneum.

Objective RNPC1 may act as an oncogene or suppressor gene in human tumors and its role in human renal cell carcinoma (RCC) remains unclear.The objective of this study was to investigate the role of RNPC1 in the development of RCC.Methods Over-expression of RNPC1 gene group (RNPC1 group) and short hairpin RNA interfering RNPC1 gene expression (shRNPC1 group) were respectively built in RCC CAKI-1 and CAKI-2.The blank control group (NC group) and negative control group (SCR group) were built as well.The qRT-PCR and western blot (WB) were used to detect the expression levels of RNPC1 mRNA and RNPC1 protein in RCC cells.Lentivirus infection was applied to establish stable expressed RCC cell lines of RNPC1 over-expression and interference.Detection was made on mRNA and protein expression levels in RNPC1 stable RCC cell lines.The effects of RNPC1 on cell proliferation, colony formation assay, migration, and invasion were detected by CCK-8 cell differentiation test, clone test, scratch test, and migration and invasion test.WB was applied to detect the change of protein expression in the EMT path of RNPC1 stable RCC cell lines and explore the molecular mechanism of RNPC1 effect on the biological function of RCC cells.Results The expression levels of RNPC1 mRNA and protein were found lower in shRNPC1 group than those in SCR group, while the expression levels of RNPC1 mRNA and protein in SCR group were higher than those NC group (P<0.05).The capability of proliferation in shRNPC1 group was stronger than that in SCR group, while the capability of proliferation in shRNPC1 group was weaker than that in NC group (P<0.05).The capabilities of cell migration and invasion were stronger in shRNPC1 group than those in SCR group, while the capabilities of cell migration and invasion in RNPC1 group were weaker than those in NC group (P<0.05).RNPC1 could inhibit the proliferation capability of RCC cells and might up-regulate the protein expression of E-cadherin and down-regulate the protein expression of β-catenin and vimentin, thus inhibiting EMT path and the capabilities of migration and invasion off RCC cells (P<0.05).Conclusion RNPC1 acts as a tumor suppressor in RCC and has the potential for the prediction of RCC prognosis.
