OBJECTIVEThe sex therapy is not yet popularized at present. This study aimed to evaluate the effect of the combination of the improved sex therapy and oral sildenafil on erectile dysfunction (ED).

METHODSA total of 3130 Uigur cases of ED received in Xinjiang Bogda Hospital were divided into a control group (n=625) and a trial group (n=2505), the former treated with oral sildenafil alone, and the latter by the combination of the improved genital therapy and sildenafil, both for 3 months and followed up at 6 and 12 months after the treatment. The therapeutic effects were evaluated and compared using IIEF-5.

RESULTSThe IIEF-5 scores of the control group were 12.80 +/- 3.76 and 18.10 +/- 2.61 before and after the treatment, and 17.35 +/- 2.73 and 16.64 +/- 2.63 at 6 and 12 months, respectively, while those of the trial group were 12.73 +/- 3.52 and 19.06 +/- 4.07 before and af- ter the treatment, and 19.86 +/- 2.42 and 20.47 +/- 2.38 at 6 and 12 months, respectively, with statistically significant differences either between pre- and post-treatment (P < 0.05) or between the control and trial groups at 6 and 12 months (P < 0.05).

CONCLUSIONThe combination of the improved sex therapy and oral sildenafil is superior to sildenafil alone in the treatment of ED, and its efficacy is relatively stable at 12 months.

To determine the content of isopsoralen in Gushuling Capsule. High performance liquid chromatography was performed on C 18 column. The chromatographic conditions were as follows: methanol-water (48∶52) as mobile phase, flow rate being 1.1?mL/min and the detecting wavelength at 245?nm. A good linearity of isopsoralen was shown in the range of 0.0342～0.2736??g, r=0.9998. The average recovery is 92.11%, RSD=1.89% (n=5). The method is with good reproducibility,RSD=2.05%.[Conclusion]This method can supply evidence for the quality control of Gushuling Capsule.

Objective To investigate the effect of berberine on insulin resistance induced by free fatty acid in 3T3-L1 adipocytes and the possible molecular mechanism.Methods 3T3-L1 adipocytes were treated with 0.5 mmol/L palmitic acid to induce insulin resistance.Berberine was used for treatment and aspirin for positive control.Glucose oxidase method was employed for measuring the glucose consumption in the medium and 2-deoxy- [~3H]-D-glucose method was used for the determination of glucose uptake.Western blot was used for the determination of IKB kinase(IKK)?SerlS1 phosphorylation,insulin receptor substrance-1(IRS-1)Ser307 phosphorylation,the protein expression of IKK?,IRS-1,phosphatidylinositol 3-kinase(PI-3K)p85 and glucose transporter 4(Glut4).Results After the treatment with 0. 5 mmol/L of palmitic acid for 24 h,glucose consumption by 3T3-L1 adipocytes was decreased by 41%,insulin-stimulated glucose transport was inhibited by 67%,IRS-1 and PI-3K p85 proteins were reduced, and phosphorylations of IKK?Ser181 and IRS-1 Ser307 were induced.The above results were reversed by adding berberine or aspirin.But Glut4 and IKK?protein abundance was not changed during this study.Conclusion Berberine significantly improves insulin resistance induced by free fatty acid in 3T3-L1 adipocytes via inhibiting IKK?serine phosphorylation.

Objective: To learn the awareness of the Three Level Social-psychological Service in Zhejiang Province and its influencing factors, so as to provide the basis for promoting the construction of social-psychological service system. Methods: The counties (cities, districts) in Zhejiang Province were divided into three levels: high, medium and low, according to economic development. The residents are selected by multistage stratified random sampling method. A questionnaire survey was conducted to collect the general information of residents and their awareness of the Three Level Social-psychological Service.The influencing factors for the awareness were analyzed by multivariate logistic regression model. Results : Of 7 114 questionnaires sent out, 6 577 valid ones were recovered, with the response rate of 92.45%. The overall awareness rates of the Three Level Social-psychological Service and service sites was 63.02% and 59.91%, respectively. The multivariate logistic regression analysis showed that the age of 40-<50 years ( OR=1.376, 95%CI: 1.077-1.758 ), permanent residence ( OR=1.474, 95%CI: 1.319-1.647 ), being the national pilots ( OR=1.200, 95%CI: 1.079-1.334 ) and having the experience of seeking mental health services before 2018 (OR=1.323, 95%CI: 1.191-1.469) were the influencing factors for the awareness of the Three Level Social-psychological Service; under 50 years old ( OR: 0.610-0.768, 95%CI: 0.423-0.991 ), permanent residence ( OR=1.571, 95%CI: 1.407-1.755 ), being the national pilots ( OR=1.368, 95%CI: 1.232-1.519 ) and having the experience of seeking mental health services before 2018 ( OR=0.733, 95%CI: 0.661-0.812 ) were the influencing factors for the awareness of the Three Level Social-psychological Service sites. Conclusions It is necessary to improve the awareness of the Three Level Social-psychological Service among Zhejiang residents. Age, permanent residence, being the national pilots, seeking mental health service experience before 2018 are associated with the awareness of the Three Level Social-psychological Service.

Objective To assess the value of three-dimensional contrast-enhanced ultrasonography (3D-CEUS) in evaluation of hepatic arteries variants.Methods Both two-dimensional contrast-enhanced ultrasonography (2D-CEUS) and 3D-CEUS were used to assess 30 patients including living donor candidates and patients with upper abdomen tumors.The reference standard was operation or CTA or DSA or MRA,and the accuracy for detecting hepatic artery variants provided by the two methods was evaluated.Arterial anatomic types were defined by using Michels classification.Results The total accuracy for detecting hepatic artery anatomy types by 2D-CEUS was 40.0% (12/30),while 83.3% (25/30) by 2D-CEUS.For convention anatomy types the accuracy on 2D-CEUS and 3D-CEUS were 40.9%(9/22)and 90.9%(20/22),respectively.The difference was statistically significant (P<0.05).For anatomy variants types the accuracy on 2D-CEUS and 3D-CEUS were 37.5%(3/8)and 62.5%(5/8),respectively.No significant difference between these two methods was observed.Conclusion 3D-CEUS was a new method in diagnosis of hepatic arteries anatomy types with practical clinical value in evaluation of the living liver donors.

Objective To assess the feasibility of three-dimensional contrast-enhanced ultrasonic cholangiography(3D-CEUSC) in cadaver liver.Methods The 3D-CEUSC was performed in 6 cases of cadaver liver.Image quality of 3D-CEUSC was evaluated.The visualization of branching orders,the degree of visibility and coincidence of morphous were compared with those of cholangiagraphy using fluoroscopy.Results The imaging quality of 3D-CEUSC was inferior to that of cholangiography with significant difference.The three-dimensional biliary tree structures were visualized in all 6 3D-CEUSC.The maximum visualization of branching orders in 3D-CEUSC was (3.67±0.52),which was equal to the results(4.00±0.63)by cholangiography (P=0.465).The degrees of visibility of biliary tree were equivalent with those by cholangiography in the first and second order with significant difference.The coincidence of morphous was excellent compared the images of 3D-CEUSC with direct X-ray cholangiography.Conclusion 3D-CEUSC is a new technique as a useful supplement to cholangiography in evaluation of biliary anatomy and variation before graft harvesting in LDLT.
