Objective To observe the clinical effect of doxazosin combined with diclofenac sodium in the treatment of bladder spasm after transurethral bipolar plasmakinetic prostatectomy (TUPKP).Methods 200 BPH patients undergoing TUPKP were randomly divided into 4 groups according to single-blind randomized controlled trial design:group A,group B,group C,group D (n =50,each).Patients in group A were given diclofenac sodium 100 mg,q12h,in anus after surgery and doxazosin 4 mg/d orally after anesthetic awareness.Patients in group B were given diclofenac sodium in anus 100 mg,q 12h in anus after surgery.Patients in group C were given doxazosin 4 mg/d orally after anesthetic awareness.Patients in group D were not given diclofenac sodium and doxazosin.Drugs were withdrawn 3 days after surgery.Results In group A,the average time of bladder spasm was (0.47±0.18) time,(0.35±0.16) time,(0.30±0.20) time at the 1st,2 nd,3 rd day respectively; the duration of bladder spasm was (3.2±1.5) min,(2.1±1.3) min,(1.4±1.2)min at the 1st,2nd,3th day respectively; the time of bladder perfusion clearance was (1.5± 0.3)days and the time of urethral catheter removal was (4.0±0.5) days.There were significant differences in above observed values between group D and the other groups (all P＜0.05).Conclusions Doxazosin combined with diclofenac sodium therapy is effective in the treatment of bladder spasm after bipolar transurethral plasmakinetic prostatectomy.

Objective To study the safety and efficacy of damage control using percutaneous transhepatic biliary drainage (PTBD) in acute cholangitis of severe type (ACST) secondary to intrahepatic choledocholithiasis.Methods The clinical data of 8 patients who received PTBD after hospital admission followed by conventional surgery for ACST when their general condition improved were retrospectively studied.Results All patients received PTBD successfully and the amount of bile drained was 100-400 ml in the first day.The general condition of these 8 patients became better after 24 h and the total bilirubin decreased for about 25-100 mmol/L after 48 h.Three patients with a platelet count of less than 20 × 109/L showed an improved count to more than 50 × 109/L 72 h after PTBD.All patients were operated at different times after the PTBD:2 received T-tube drainage,3 T-tube drainage combined with left hepatectomy,and 3 choledochojejunostomy.Seven patients recovered uneventfully,but 1 developed hepatic failure with the total billurubin rose to more than 200 μmol/L.He was discharged home with the PTBD tube.During the waiting time of 7 days to 3 months before surgery,the tubes were kept patent and no mortality or morbidity such as bleeding,bile leakage,and peritonitis occurred.Conclusions PTBD was a safe and efficacious procedure for patients who were in a serious condition with ACST secondary to intrahepatic choledocholithiasis.It was more likely to be successful as it is minimally invasive and therefore well-tolerented.It reduced the biliary pressure,relieved the ongoing sepsis,and was a good preparatory procedure before any conventional surgery.

This paper takes the establishment of the College of Basic Gynecology and Obstetrics in the First Affiliated Hospital of Sun Yat-sen University as an example, and through reviewing its establishment background, organizational system (including organizational structure, regulation construction, platform construction and teacher construction) and curriculum system (including curriculum goals and principles, curriculum format, specific curriculum settings, assessment system and evaluation feedback system), so that we can understand the development of the Basic College of Obstetrics and Gynecology and its role in the standardized residency training. This general hospital specialized college model focuses on training comprehensive, professional, applied medical talents and clinically competent physicians, which plays an important role in the standardized residency training, and improves the theoretical knowledge and technical skills of the residents. Running of the college has been widely recognized by peers, This college model is worthy of further promotion.

Objective:To evaluate the clinical application potential of a novel prostate specific membrane antigen (PSMA) targeted PET tracer 68Ga-PSMA-NYM032 in patients diagnosed initially with prostate cancer. Methods:A total of 63 patients (age (68.7±8.7) years) with suspected prostate cancers who received 68Ga-PSMA-NYM032 PET/CT imaging in Affiliated Hospital of Jiangnan University between March 2022 and January 2023 were enrolled prospectively. The diagnostic efficiency of 68Ga-PSMA-NYM032 PET/CT imaging was evaluated in a patient-centered manner. The ROI was drawn to obtain SUV max by semi-quantitative analysis with visual analysis, and the diagnostic threshold of SUV max was obtained by ROC curve analysis. The correlations of SUV max in primary foci with total prostate specific antigen (tPSA) and Gleason score (GS) were analyzed by Spearman rank correlation analysis. Based on the D′Amico risk stratification (prostate specific antigen (PSA)>20 μg/L and ≤20 μg/L, GS>7 and ≤7), the detection rates of metastases by 68Ga-PSMA-NYM032 PET/CT imaging in different stratifications were analyzed by Fisher exact test, and the differences between SUV max of metastases in different stratifications were determined by Mann-Whitney U test. Results:The accuracy of 68Ga-PSMA-NYM032 PET/CT imaging was 92.06%(58/63), the sensitivity was 96.55%(28/29), the specificity was 88.24%(30/34), the positive predictive value was 87.50%(28/32), the negative predictive value was 96.77%(30/31), and the optimal SUV max threshold was 6.9. 68Ga-PSMA-NYM032 showed varying degrees of high uptake in the primary foci of prostate cancer, and SUV max were positively correlated with tPSA and GS ( rs values: 0.657, 0.592, P values: <0.001, 0.001). Stratified analysis showed a statistically significant difference in the detection rate of bone metastases by 68Ga-PSMA-NYM032 PET/CT between the GS>7 and GS≤7 subgroups (9/17 vs 1/12; P=0.019), while no statistical significances were observed in the detection rates of bone metastases or lymph node metastases of another subgroups (all P>0.05). In addition, none of the differences in SUV max of metastases in patients with different stratifications were statistically significant ( z value: from -1.57 to -0.50, all P>0.05). Conclusions:68Ga-PSMA-NYM032 PET/CT imaging has good diagnostic efficacy for prostate cancer, and it may provide a new strategy for the precise diagnosis and treatment of prostate cancer. Besides, GS stratification may affect the detection rate of bone metastases by 68Ga-PSMA-NYM032 PET/CT imaging.

Abstract During the yellow fever epidemic in Angola in 2016, cases of yellow fever were reported in China for the first time. The 11 cases, all Chinese nationals returning from Angola, were identified in March and April 2016, one to two weeks after the peak of the Angolan epidemic. One patient died; the other 10 cases recovered after treatment. This paper reviews the epidemiological characteristics of the 11 yellow fever cases imported into China. It examines case detection and disease control and surveillance, and presents recommendations for further action to prevent additional importation of yellow fever into China.
