Objective： To investigate the mental health of freshmen in Xiamen Un iversity. Methods: A total of 2 226 freshmen of 1998 from Xiamen University comp leted the SCL-90. Results: There were 153 students who sco red above 3 on one or more sub-scales. The most common mental health problems were compulsion, interpe rsonal sensitivity, and paranoia. Students from the College of Foreign Language, Art Education, Medicine, and Humanities reported more mental problems than thos e from the College of Computer and Information Engineering, Physics and Electrom echanical Engineering. Girls were more likely to suffer from phobic anxiety, dep ression, somatization, anxiety, and interpersonal sensitivity than boys, and the y were less hostile than boys. Conclusion: The mental heal th conditions were fou nd to be different for students from different colleges and departments. There w as also significant gender difference in major mental health problems.

Objective To evaluate the clinical experience of applying the combined tacrolimus (FK506) and mycophenolate mofetil (MMF) in simultaneous pancreas and kidney transplantation (SPKT) with bladder drainage of pancreatic secretion. Methods SPKT was performed for 14 consecutive patients. On the first day after transplantation, triple immunosuppression therapy was appliedwith FK506(0.07-0. 15 mg·kg-1·d-1), MMF(1.0- 1.5 g/d) and prednisone (25 mg/d). The FKS06 blood concentration after oral administration was assayed by the means of MEIA. The occurrence of rejection and the drug toxicity were monitored and recorded. Results Nine recipients survived with the grafts and their general conditions were well. They were followed up for 18--70 months (mean 34 months). There was no early stage complication such as pancreatic fistula and thrombosis after operation. The blood glucose level returned to normal range after operation. All recipients survived over 1 year. Of them, 3 cases survived for 1-3 years,1 case survived for 3-4 years, 1 case survived 4-5 years and 4 cases survived over 5 years. All the cases had normal blood glucose level and early graft function. Removal of allograft pancreas was performed on one patient because of hyperacute rejection. There were 4 cases died. Of whom, one case was diagnosed with duodenal stump leak 45 days after transplantation and he died of corrosive hemorrhage 7 months after operation. One patient died of unexpected heart disease. The 3rd patient died ol multiple organ failure and the fourth case died of acute rejection. Four cases with acute rejection, 2 cases with renal toxicity and 1 case with hepatotoxicity were observed. Conclusions The combination of TAC/MMF has synergetic effect. The application of this combination has good immunosuppression result. It could effectively reduce the risk of acute rejection and improve graft survival in SPKT recipients.

BACKGROUND: Following renal transplantation, native renal pelvic or ureteral tumor occurs not only on one side, but also on both sides simultaneously or continuously.OBJECTIVE: To describe a new procedure in managing native renal pelvic or ureteral tumor, in which, retroperitoneal laparoscopic nephroureterectomy was first done followed by transurethral resection of ureteral orifice, and finally the kidney and the complete ureter with a bladder cuff were taken out through a midline abdomen incision, and to validate its feasibility.DESIGN, TIME AND SETTING: A technique modification experiment was performed at the Department of Urinary Surgery, Third Hospital, Peking University between July 2004 and March 2006.PARTICIPANTS: Eight patients (7 males and 1 female) with native renal pelvic or ureteral tumor who received laparoscopic nephroureterectomy with bladder cuff resection were included into this study. Of them, 4 cases had bilateral lesions. Laparoscopic nephroureterectomy with bladder cuff resection was conducted 12 times totally.METHODS: Retroperitoneal laparoscopic nephroureterectomy was first done in the lateral decubitus, followed by transurethral resection of the ureteral orifice with resectoscope in the lithotomy position, and finally, an incision was created in the lower midline abdomen to allow dissection of the distal ureter and bladder cuff and intact specimen extraction. Postoperatively, intravesical chemotherapy was routinely performed to prevent tumor recurrence. The patients were followed up at 3, 6, and 12 months after surgery, and once a year thereafter.MAIN OUTCOME MEASURES: Surgery time, blood loss volume, pathological report, tumor recurrence time, tumor-free survival time, and complications.RESULTS: The mean surgery time was 3.8 hours (range: 2.5-7 hours). The mean hemorrhage volume was 240 mL (range: 50-1 200 mL). Two cases needed blood transfusion, 600 and 1 000 mL, respectively. Transitional cell carcinoma grade Ⅲ was found in 3 cases, grade Ⅱ in 4 cases, and grade Ⅰ-Ⅱ in 4 cases. In addition, there was 1 case presenting with tumor breaking through the serous membrane of the ureter and 1 case suffering from poorly differentiated adenocarcinoma. The tumor recurred locally in one case 6 months after surgery, and the remaining cases all survived in a tumor-free state.CONCLUSION: After renal transplantation, laparoscopic nephroureterectomy with bladder cuff resection through a lower midline abdomen incision is feasible for treatment of native renal pelvic or ureteral tumor, with low tumor recurrence rate and satisfactory excision effects.

We retrospectively analyzed the clinical data of 615 recipients (347 male and 268 female, age range: 9-75 years weighing 38-100 kg) who received renal transplantation in the Third Hospital of Peking University from January 2001 to July 200 to summarize the causes and experience of surgical complications after renal transplantation. Kidney of donors with brain death wa obtained using modified in situ hypothermy perfusion method, and kidney from living bodies was obtained using posterio abdominal cavity open or abdominal speculum method. After renal transplantation, the immunosuppressive therapy including FK50 or Cyclosporine A + mycophenolate mofetial or mizoribine + Prednisone was applied and regulated according to the variation o concentration in whole blood. Recipients were followed up for at 1 year. Of 615 patients, 29 cases developed surgical complication with the incidence rate of 4.72%; Graft lost in 5 cases due to surgical complications after renal transplantation. The achievement rati of operation was 99.19%.

Background::Studies suggest seasonal fluctuations of symptoms in Parkinson’s disease (PD) patients in Western countries. However, the association between seasonal change and variation in nonmotor symptoms (NMS) in Chinese PD patients is unclear. Here, we studied whether there is a change rule with annual cycle with severity of NMS for patients with PD in Southeast China.Methods::We studied 1005 PD patients between April 2008 and October 2020. Patients were classified into four seasons according to the 24 Chinese solar terms, based on assessment date. We compared comprehensive NMS scales and polysomnography parameters among groups and conducted further analysis of disease severity.Results::Among the 1005 patients studied, the mean age was 64.2 ± 9.7 years and 569 (56.6%) of them were men. Relative to the summer group, patients assessed during winter had higher Scales for Outcomes in Parkinson’s disease-Autonomic Dysfunction (SCOPA-AUT) scores ( P = 0.045). The sleep efficiency factor scores of Pittsburgh Sleep Quality Index in patients were higher during spring than summer ( P = 0.009). Among patients who completed polysomnography during the same period ( n = 135), compared with summer follow-ups, we observed a higher percentage of NREMS1 in winter and spring follow-ups ( P = 0.042, P = 0.011), a higher NREMS1 time in spring follow-ups ( P = 0.0024), a lower NREMS2 time in winter follow-ups ( P = 0.007), and a higher percentage of phasic rapid eye movement (REM)-sleep without atonia in autumn and winter follow-ups ( P = 0.026 and P = 0.020, respectively). In a subset of patients with PD and REM sleep behavior disorder (RBD; n = 182), those visited during winter had higher scores for RBD questionnaire-Hong Kong and its factor 1 (dream-related sub-score) than those visited during summer ( P = 0.034, P = 0.020). We observed similar findings for SCOPA-AUT and sleep efficiency factor scores in early stage patients in subgroup analysis. Conclusions::PD patients assessed for follow-up during summer showed less severe symptoms of autonomic dysfunction and RBD symptoms than those assessed in winter, and less sleep disturbance than those in spring and winter, suggesting that seasonal change and NMS fluctuation are related, especially in patients with early stage PD.

Objective:To verify the ability of the newly developed ultra-high resolution CT (U-HRCT) for displaying the fine bony anatomy of temporal bone.Methods:The cone-beam CT architecture was used on U-HRCT. The focus size of X-ray generator was 0.27 mm × 0.29 mm, the rated tube voltage was 60-100 kV, and the unit size of flat panel detector was 0.074 8 mm×0.074 8 mm. From October to December 2019, 16 adult head specimens (32 temporal bones, provided by Huanghe University of Science and Technology) were imaged using U-HRCT. The scanning mode was small-field-of-view and high-resolution scanning for unilateral temporal bone. The scanning parameters were: voltage 100 kV, current 3.5 mA, rotation time 40 s, reconstructed field of view 65 mm×65 mm, voxel size 0.1 mm×0.1 mm×0.1 mm, layer number 370, slice thickness 0.1 mm, and slice interval 0.1 mm. The ultimate spatial resolution of the system was detected using a phantom with line pair card, after the scanning with the same parameters. Through multi-planar reconstruction and minimum intensity projection method, a total of 6 anatomical positions of 4 structures (stapes footplate, cochlear axis bottom, vestibular aqueduct internal orifice and isthmus, cochlear aqueduct internal orifice and auditory sac segment) were scored with 1-3 points. The Wilcoxon test was used to compare the difference of bilateral scores of each structure.Results:The phantom test results showed that the ultimate spatial resolution of the system was ≥4.0 lp/mm. The scores of stapes footplate, cochlear axis bottom and vestibular aqueduct internal orifice were ≥2 points, with a display rate of 100%. The display rates of vestibular aqueduct isthmus, cochlear aqueduct internal orifice and auditory sac segment were 87.5% (28/32), 71.9% (23/32) and 53.1% (17/32), respectively. There were no significant differences in left and right scores of all anatomical structures ( P>0.05). Conclusion:The newly developed U-HRCT has good display ability for fine bony anatomy of temporal bone and has great clinical application potential.

【Objective】 To investigate the effects of WM-3835, a histone acetyltransferase KAT7 (KAT7) inhibitor, on the proliferation and migration of bladder cancer cells and to explore the possible mechanism. 【Methods】 Human ureteral epithelial immortalized cell line SV-HUC-1, and bladder cancer cell lines UM-UC-3 and T24 were treated with different concentrations of WM-3835 (0, 10, 20, 30, 40 μmol/L). After 48 hours, the effects of WM-3835 on the proliferation, cell cycle distribution and migration of cells were detected with MTT assay, flow cytometry, scratch and Transwell assay, respectively. The expressions of cyclin D1 (cyclin D1), proliferating nuclear antigen (PCNA), matrix metalloproteinase 9 (MMP9) and neurocadherin (N-cadherin) were detected with Western blotting and real-time quantitative PCR. 【Results】 WM-3835 significantly inhibited the proli-feration of bladder cancer cells in a dose-dependent manner. After treatment with WM-3835, the cycle of UM-UC-3 and T24 cells were blocked in the G0/G1 phase, the proliferation was effectively inhibited, and the migration was significantly wea-kened. The expressions of cyclin-D1, PCNA, MMP9 and N-cadherin were down-regulated. 【Conclusion】 WM-3835 can inhibit the proliferation and migration of bladder cancer cells, and has the potential as a chemotherapeutic agent for bladder cancer.

Objective:To explore independent predictors for poor outcome at 3 months in elderly patients with acute cerebral infarction(ACI)treated with intravenous thrombolysis(IVT), and to develop a nomogram-based predictive model.Methods:This was a retrospective cohort study.Clinical, laboratory and imaging data of 346 elderly patients with ACI treated with IVT from January 2016 to April 2021 in our hospital were collected.Poor outcome was defined as a modified Rankin Scale(mRS)score >2 at 3 months after the stroke.Logistic regression analysis was used to screen for independent factors predicting poor outcome in elderly ACI patients treated with IVT, and a corresponding nomogram model was developed using the R software.The ROC curve, calibration plots and decision curve analysis were used to evaluate discrimination, calibration and clinical application value of the nomogram model.Results:Among 346 candidates, 109 developed a poor outcome, representing a rate of 31.5%.Logistic regression analysis showed that symptomatic hemorrhagic transformation( OR=15.647, 95% CI: 8.913-27.454), stroke severity(moderate stroke, OR=3.322, 95% CI: 1.414-7.811; moderate-severe stroke, OR=8.169, 95% CI: 4.102-16.258; severe stroke, OR=9.653, 95% CI: 5.440-17.121), stroke-associated pneumonia( OR=2.239, 95% CI: 1.134-4.420), and heart failure( OR=2.758, 95% CI: 1.424-5.336)were independent predictors for poor outcome at 3 months in elderly ACI patients treated with intravenous thrombolysis(all P<0.05). With the area under curve(AUC-ROC)value at 0.85(95% CI: 0.80-0.89), the nomogram model, which was composed of the above four predictors, demonstrated good discrimination.On the calibration plot, the mean absolute error was 0.020, indicating that the model had good calibration.Decision curve analysis revealed that the model had good clinical application value. Conclusions:The nomogram model composed of symptomatic hemorrhagic transformation, stroke severity, stroke-associated pneumonia and heart failure may predict poor outcome at 3 months in elderly ACI patients treated with IVT, with high prediction accuracy and high clinical application value.
