Objective:To explore the relation of depressive and anxiety symptoms to defense mechanism in transgender population.Methods:Totally 451 transgender patients in the sexual and psychological outpatient depart-ment of a hospital were selected.They were assessed with the self-Rating Depression Scale(SDS),Self-Rating Anxiety Scale(SAS)and Defense Mechanism Scale(DSQ).The SDS standard score of ≥53 was classified as having depressive symptoms,and the SAS standard score of ≥50 was classified as having anxiety symptoms.Re-sults:The detection rates of depression and anxiety were 46.8％and 28.8％respectively.Multiple linear regression analysis showed that SDS scores were positively correlated with DSQ scores of projection,conceit,complaint,with-drawal,somatization,control,isolation and identity(β=0.08-0.22),while SDS scores were negatively correlated with DSQ scores of sublimation,depression,omnipotence with incompetence and denial(0=-0.09--0.19).The SAS scores were positively correlated with the DSQ scores of projection,latent manifestation,somatization,control,isolation,identity,and consumption tendency(0=0.09-0.26),while the SAS scores were negatively cor-related with the DSQ scores of sublimation,depression,omnipotence accompanied by incompetence,and denial(β=-0.09--0.15).Conclusion:The proportion of depression and anxiety symptoms detected in the transgender group is higher,which may be related to the use of some defenses.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To prepare chitosan/gelatin hydrogel composite hemostatic materials loaded with Panax notoginseng (PN/CMC/GMs) and evaluate their performance. Methods:PN/CMC/GMs hydrogel composite hemostatic material were prepared by the freeze-drying method, and their morphology was observed by scanning electron microscopy. Their rheological properties were observed by a rheometer. Their water absorption rate was tested by dissolution. Their biocompatibility was detected by a cytotoxicity assay. Their rapid hemostatic effect was tested using a SD rat liver hemorrhage model.Results:PN/CMC/GMs composite hemostatic materials were prepared in a lattice-like structure with certain porosity. With the increase in Panax notoginseng powder content, the modulus of PN/CMC/GMs increased accordingly, and the mechanical strength increased. PN/CMC/GMs have better water absorption and expansion functions, which can form compression hemostasis and concentrated blood to achieve rapid hemostasis, and have good biocompatibility. Hemostasis experiments showed that the hemostatic time and hemostatic effect of PN, CMC/GMs hemostatic materials on liver injury in rats were better than those of the blank control group. Conclusions:PN/CMC/GMs have good hemostatic effect and biocompatibility and have the potential for further research and clinical application.

Objective:To explore the differences in clinical characteristics and treatment outcomes between patients with type A and type B alcohol dependence, and to find the independent risk factors of relapse.Methods:Alcohol-dependent male patients attending the Addiction Medicine Center of Beijing Huilongguan Hospital from January 2018 to December 2020 were selected for the study and divided into type A alcohol-dependent group ( n=77) and type B alcohol-dependent group ( n=87). All patients were given acute detoxification treatment and were followed up after treatment on relapse to drinking. Differences in demographic and clinical data were compared between the two groups, and differences in treatment outcomes between the two groups at different time points over 3 months were compared. Patients were divided into relapse group and non-relapse group according to whether they drank again after 3 months. Logistic regression model was established to screen the risk factors of relapse of alcohol-dependent patients by SPSS 25.0 software. Results:There was no significant difference between the two types of patients in years of education, marital status, smoking status and working status(all P>0.05), but the proportion of co-residents( χ2=5.69, P=0.017) and the proportion of positive family history of alcoholism were significant difference between the two type of patients( χ2=13.32, P<0.001). There were statistically significant differences between the two types of patients in the onset time( t=-7.28, P<0.001), the first drinking age( t=-2.36, P=0.020), the proportion of drinking in the morning( χ2=7.83, P=0.005), psychotic symptoms( χ2=4.31, P=0.038), convulsions after withdrawal( χ2=5.30, P=0.021), and alcohol use disorder identification test(AUDIT) score( t=4.30, P<0.001). At the 4th and 8th weekend of the follow-up, there were statistically significant differences in drinking frequency(0(0, 3), 0(0, 0), Z=-4.13, P<0.001; 3(0, 3), 0(0, 3), Z=-4.42, P<0.001) and relapse rate (40(45.98%), 9(11.69%), χ2=22.92, P<0.001; 61(70.11%), 24(31.17%), χ2=24.82, P<0.001) between the two types of alcohol dependence patients after drinking again. After 12-week follow-up, there were statistically significant differences between the two types of alcohol-dependent patients in the interval of first drinking(20(7, 30)d, 88(38, 90)d, Z=-7.83, P<0.001), the cumulative duration of abstinence(4(0, 8)weeks, 12(4, 12)weeks, Z=-5.13, P<0.001), the cumulative rate of abstinence(71(81.60%), 25(32.47%), χ2=40.62, P<0.001), the frequency of drinking after abstinence(3(3, 3), 0(0, 3), Z=-5.54, P<0.001), and the reduction of daily average alcohol consumption( t=3.36, P<0.001). Logistic regression model showed that type B alcohol dependence ( OR=3.121, P=0.03, 95% CI: 1.12-8.72) and AUDIT score ( OR=1.498, P<0.01, 95% CI: 1.29-1.74) were the risk factors for relapse of alcohol-dependent patients. Conclusions:Patients with type A and type B alcohol dependence have obvious differences in clinical characteristics and treatment outcomes, and type B alcohol dependence is independent risk factor for relapse to drinking in alcohol-dependent patients, which validate the rationality and necessity of alcohol dependence subtypes.

Objective:To explore the application value and initial clinical experience of fluorescence-enhanced laparoscopy combined with indocyanine green in radical cystectomy with pelvic lymphadenectomy.Methods:A retrospective analysis was performed on the clinical data of a total of 8 patients admitted from May 2018 to August 2019 who underwent laparoscopic radical cystectomy with pelvic lymphadenectomy for muscle-invasive bladder cancer using the fluorescent laparoscopy system.There were 6 males and 2 females; aged 58 to 71 years, with an average of 65.8 years. The preoperative pathology was urothelial carcinoma, with 2 cases in T 2a stage, 4 cases in T 2b stage, and 2 cases in T 3a stage. The patient was injected a total of 2 ml of 2.5 mg/ml of indocyanine green through a rigid cystoscope using a 18 gauge cystoscope injection needle before surgery. The PINPOINT endoscopic fluorescence camera system performed surgery in real-time. A systematic examination of the surgical area under near-infrared fluorescence was performed every 5 minutes. Observation and recording of indocyanine green combined with fluorescence laparoscopy to mark the bladder tumor area and identify the sentinel drainage. Results:Eight cases were successfully completed under the fluorescence laparoscopic system.In terms of tumor markers, cystoscopy with indocyanine green allowed 7 of the 8 patients to successfully identify the tumor area under fluorescent laparoscopy. Six of the 8 patients with sentinel lymph nodes identified by indocyanine green lymphangiography were also successful, of which 3 were positive for lymph nodes. At the same time, intravenous indocyanine green was used to observe that the blood supply to the bladder and the end of the ureter was good. The operation time was 190-310 minutes, with an average of 235 minutes; the bleeding volume was 150-380 ml, with an average of 180 ml; the postoperative hospital stay was 10-22 days, with an average of 14.5 days. Postoperative pathological staging 2 cases in T 2a stage, 3 cases in T 2b stage, 3 cases in T 3a stage, with total number of lymph nodes 8-14, average 10. The 8 cases were followed-up for 4-12 months, average 5.5 months, without indocyanine green related complications. Conclusions:Indocyanine green fluorescent laparoscopy can accurately locate and identify the bladder tumor area and pelvic lymph nodes during radical cystectomy, which can reduce positive margins and unnecessary enlarged lymph node dissection.

Objective To evaluate the efficacy and safety of single flexible ureteroscope vs.flexible ureteroscope combined with intraoperative ultrasonography guided in the endogenous renal cyst incision and drainage.Methods Retrospective analysis of case data of 64 patients with endogenous renal cysts admitted from January 2015 to December 2017.All the patients undrwent contrast-enhanced CT,urinary tract imaging,ultrasound B to confirm bosniak classification Ⅰ and Ⅱ renal cyst.The patients (38 males,26 females) were divided into single flexible ureteroscope group [group A,32 cases of patients,average age (54.2 ±6.6) years,unilateral or bilateral cystic patients:19 cases/ 13cases,simple cyst of kidney or polycystic kidney:24 cases/8 cases,average maximum diameter of the renal cyst (5.4 ± 1.3) cm,combined with renal calculus:8 cases,combined with hydronephrosis:7 cases,1 case who had the history of laparoscopic renal cyst decapitation,1 case who had the history of percutaneous renal cyst puncture] and flexible ureteroscope group combined with intraoperative ultrasonography guided [group B,32 cases of patients,average age (52.3 ± 9.3) years,unilateral or bilateral cystic patients:21 cases/11 cases,simple cyst of kidney or polycystic kidney:25 cases/7 cases.Average maximum diameter of the renal cyst (5.3 ±1.2) cm,combined with renal calculus:9 cases,combined with hydronephrosis:8 cases,2 case who had the history of laparoscopic renal cyst decapitation,1 case who had the history of percutaneous renal cyst puncture].The double J stent was placed two weeks before the surgery into the body of patients.During the operation,the surgical procedure were used by the electronic flexible ureteroscope and holmium laser (0.8 J,20 Hz),combined with ultrasound B in the monitoring,to find the suitable incision position.It would be defined as the successful result if we could put the head of flexible ureteroscope into the inside of renal cyst and see the image of mist in the screen of ultrasound B.According to the standard,the result of operation wound be defined compared to before operation (success:shrink more than 80％ or maximum diameter was smaller than 1 cm;improvement:shrink about 50％-79％;ordinary result:shrink about 30％-49％;failure:shrink smaller than 30％).Effective rate =(success cases + improvement cases)/total cases.We compared the differences of two groups in the time,efficacy,safety and complication of surgery.Results Compared the results of single flexible ureteroscope groups vs flexible ureteroscope group combined with intraoperative ultrasonography guided in the success cases of surgery,after 8-30 months following-up,total operative complication rate was [8 cases(25％)vs.1 case(3.1％)],success rate of operation in 6 month later [(20 cases (62.5％) vs.28 cases (87.5％)].Flexible ureteroscope group combined with intraoperative ultrasonography guided had advantages statistically (P ＜ 0.05).However,there was no statistical difference for the two groups in the time of operation [(33.4 ± 6.7) min vs.(35.1 ± 8.6) min],single operative complication (intraoperative wounding bleeding:3 cases vs.1 case,postoperative urinary infection:3 cases vs.0 case,perinephric space effusion:2 cases vs.0 case,renal function impairment:1 case vs.0 case)(P ＞0.05).Conclusions Flexible ureteroscope combined with intraoperative ultrasonography guided can help the urologist can improve the success rate of surgery and reduce the chance of surgical injury intraoperatively.

Objective To study the constituents of urinary stones in patients in Zhejiang,and analyze the composition difference between patients from northern Zhejiang province and southern Zhejiang province.Methods From October 2012 to October 2018,clinical data of 4 423 urinary stone patients treated in Sir Run Run Shaw Hospital,the Second Affiliated Hospital of Wenzhou Medical University,and Huzhou First People's Hospital was retrospectively analyzed.Infrared spectrum was used to analyze urinary calculi constituents.Among 4 423 patients,there were 3 041 males and 1 382 females,male to female ratio was 2.2∶ 1,and the mean age was (51.2 ±16.5) years.There were 2 974 northern Zhejiang patients and 1 449 southern Zhejiang patients.High incidence age group was 41-60 years [48.2％ (2 136/4 423)].The distribution characteristics of urinary calculi constituents in different groups of sex,age,and region were analyzed.Results Among the 4 423 cases,the mixed urinary stones were dominant in the urinary calculus [73.1％ (3 235/4 423)],in which,the most component was the calcium oxalate monohydrate + calcium oxalate dehydrate + carbonated apatite [36.2％ (1 604/4 423)];among the pure stones,the most component was the calcium oxalate monohydrate [16.3 ％ (719/4 423)].Carbonated apatite stones [70.1％ (970/1 382) vs.61.0％ (1 856/3 041),P ＜0.05] and magnesium ammonium phosphate stones [12.7％ (176/1 382) vs.4.9％ (150/3 041),P ＜ 0.05] were both more prevalent in females than males,but uric acid stones[10.6％ (325/3 041) vs.5.8％ (81/1 382),P ＜0.05] were more common in males than females.The proportions of calcium oxalate stones[90.6％ (961/1 060) vs.76.2％ (935/1 227),P ＜0.05],carbonated apatite stones [77.6％ (823/1 060) vs.50.7％ (623/1 227),P ＜ 0.05],and magnesium ammonium phosphate stones[9.1％ (97/1 060) vs.6.5％ (80/1 227),P ＜0.05] of 0-40 years group were all higher than ＞ 60 years group,however,uric acid stones were more frequent in ＞ 60 years group [3.5％ (38/1 060) vs.17.0％ (209/1 227),P ＜ 0.05].The proportion of calcium oxalate stones in southern Zhejiang was lower than northern Zhejiang [79.0％ (1 145/1 449) vs.89.4％ (2 661/ 2 974),P ＜ 0.05].However,carbonated apatite stones [71.5％ (1 037/1 449) vs.60.1％ (1 789/2 974),P ＜ 0.05],magnesium ammonium phosphate stones [15.1％ (220/1 449) vs.3.5％ (106/ 2 974),P ＜ 0.05],and uric acid stones [10.7％ (156/1 449) vs.8.4％ (250/2 974),P ＜ 0.05] were more prevalent in southern Zhejiang than northern Zhejiang.Conclusions The distribution of constituents of urinary stones in Zhejiang was different in genders,age,and regions.Carbonated apatite stones and magnesium ammonium phosphate stones were more prevalent in females and young people,and uric acid stones were more common in males and old people.Calcium oxalate stones were more common in youths.Moreover,calcium oxalate stones were more frequent in northern Zhejiang,and carbonated apatite stones,magnesium ammonium phosphate stones and uric acid stones were common in southern Zhejiang.

Objective To evaluate the feasibility and clinical efficacy of retroperitoneal laparoscopic partial nephrectomy (RLPN) with individual operation plan in treatment of small renal cell carcinoma (RCC). Methods 98 patients with small RCC who was treated by RLPN from June 2012 to June 2016 were retrospectively analyzed. There were 57 males and 41 females with a mean age of 52 years old (ranging 28 ~ 75 years old). 52 cases were located on the right side while 46 cases were left. The mean tumor size was 3.1 cm in diameter (ranging 0.8 ~ 4.5 cm). 87 patients (A group) were underwent standard RLPN with clamping main renal artery. 7 patients (B group) with exophytic RCC were performed without clamping renal artery, but with separating main renal artery and prepared for possible clamping. 4 patients (C group) with endophytic RCC were performed with clamping renal artery under ultrosound monitoring. The feasibility and outcomes were evaluated by surgical and oncological outcomes. Results 84 cases among A group were underwent standard RLPN successfully, with 2 cases converted to open surgery and 1 case failed to excising tumor completely and converted to laparoscopic radical nephrectomy. The amount of bleeding during operation was 30 ~ 350 ml, average 93 ml, operation time was 70 ~ 245 min, average 127 min, warm ischemia time 20 ~ 42 min, average 26 min. 6 cases among B group were performed successfully without clamping renal artery with 1 case converted to clamp renal artery for 15 min during the operation because of obvious bleeding. The amount of bleeding was 160 ~ 380 ml, average 220 ml, operation time was 85 ~ 215 min, average143 min. 4 cases of C group were all performed successfully, The amount of bleeding was 35 ~ 250 ml, average 85 ml, operation time was 110 ~ 235 min, average 175 min, warm ischemia time 25 ~ 40 min, average 28 min. With a mean follow up of 28 months (ranging 18 ~ 42 months), there was only 1 case of A group occured local recurrence and lung metastases and accepted molecular targeted therapy with Sorafenib. Conclusion RLPN with individual operation plan in treatment of small RCC is safe and effective, the long-term effect of the procedure needs further investigation.

Objective To investigate the clinical value of splenic autotransplantation in patients with severe splenic trauma. Methods A prospective case-control study were performed in 120 patients with traumatic spleen rupture including the treatment group 72 patients and the control group 48 patients. The treatment group were treated with splenectomy plus spleen autotransplantation and the control group merely under splenectomy. Compare the operation time,operative blood loss,postoperative hospital stay,postoperative complications and the immune indexes before and different period after operation. Results Autologous spleen transplantation takes more time than merely splenectomy(P<0.05),but the operative blood loss,postoperative hospital stay and postopera-tive complications were no significant difference. 1 days after operation,the immune indexes of two groups were significantly lower than those before operation(P < 0.05),and 1 week after operation the immune indexes of two groups were significantly elevated(P<0.05).The immune indexes of the treatment group were better than those of the control group 3 months after operation(P < 0.05),and there was no significant difference compared with preoperative. Conclusion Splenectomy cause the decrease in the immune function,but the immune function can quickly rise to a certain level in short term.The splenic autotransplantation can effectively restore the immune func-tion to the preoperative level.

Objective To explore the screening value of infection probability score(IPS) in early prediction of urosepsis after flexible ureteroscope.Methods Totally 304 patients with upper urinary calculi after flexible ureteroscope from June 2013 to August 2015 were selected as the research object by purposive sampling method. The participants were divided into the infected group and the non-infected group based on systemic inflammatory response syndrome(SIRS) diagnostic criteria. The diagnostic test and ROC curve analysis were used to evaluate the diagnostic value and identify an appropriate cut-off score.Results The area under curve (AUC) of IPS was 0.812 (P<0.01) and the cut-off score was 14. The IPS retest Cronbach′s α was 0.754 and it had good construct validity. The sensitivity,specificity and Youden index of IPS ≥14 were 76.0%,85.0%,and 0.61,which indicated good consistency with SIRS diagnosis.Conclusions IPS has a high screening value in early prediction of urosepsis after flexible ureteroscope,and it can be applied to clinical practice.
