Objective:To compare clinical characteristics,treatment patterns and physiological indicators in bipolar disorder(BD)patients with different age of onset.Methods:Totally 380 patients with DSM-5 BD were se-lected in this study.Psychiatrists diagnosed the patients using the Mini International Neuropsychiatric Interview.The clinical information questionnaire and the Global Assessment of Functioning scale were utilized to collected clinical characteristics,treatment status,and physiological indicators.The onset age of BD was divided into 21 and 35 years as cut-off points.Multivariate logistic regression and linear regression were used to analyze related factors.Results:Among the 380 patients with BD,199 cases were early-onset group(52.4％),121 cases were middle-onset group(31.8％),and 60 cases were late-onset group(15.8％).There were 26.6％of patients in the early-onset group in-itially diagnosed as depression,23.1％in the middle-onset group,and 11.7％in the late-onset group.Multivariate analysis revealed that compared to the early-onset group of BD,the middle-onset(OR=2.22)and late-onset(OR=4.99)groups had more risk to experience depressive episodes,and the late-onset group(OR=6.74)had 6.74 times of risk to suffer from bipolar Ⅱ disorder.Additionally,patients in the middle-onset(β=-1.52)and late-on-set(β=-4.29)groups had shorter durations of delayed treatment,and those in the middle-onset(β=-1.62)and late-onset(β=-3.14)groups had fewer hospitalizations.Uric acid levels were lower in both the middle-onset(β=-28.39)and late-onset(β=-31.47)groups,and total cholesterol level was lower in the middle-onset group(β=-0.23).Conclusion:Patients with BD in different age of onset show significant differences in clinical charac-teristics,treatment conditions and physiological indicators.

Objective: Self-determination theory (SDT) deems that people have three causality orientations: autonomy orientation, control orientation, and impersonal orientation. Previous studies suggested that lower autonomy orientation or higher control and impersonal orientations may be associated with more addictive behaviors. Our study aimed to investigate if these associations exist in Internet gaming disorder (IGD), and if sensation seeking, anxiety, and depression could influence the associations between causality orientations and IGD symptoms. Methods: A total of 1,400 college students completed the Internet Gaming Disorder Scale, General Causality Orientation Scale, Brief Sensation Seeking Scale, Generalized Anxiety Disorder Scale, and Patient Health Questionnaire. Correlation, multiple linear regressions, structural equation model (SEM) analyses, and moderation analyses were conducted to explore the associations. Results: The control and impersonal orientations were positively associated with IGD symptoms, while the autonomy orientation was negatively associated with them. Moreover, SEM analyses showed that the autonomy-IGD relationship was totally mediated by anxiety and depression, the impersonal-IGD relationship was partially mediated by anxiety, and the control-IGD relationship was partially mediated by depression. Finally, the effects of causality orientations on IGD were moderated by sensation seeking. Conclusion Overall, autonomy orientation is linked to fewer gaming problems, whereas control and impersonal orientations are associated with more gaming problems. Moreover, the relationships between causality orientations and IGD symptoms are mediated by anxiety and depression and moderated by sensation seeking. Our findings inform theory on the motivations of gaming behaviors and may shed light on the prevention and intervention of IGD from the perspective of SDT.

Objective:To compare the efficacy of pneumovesicoscopic Cohen and Politano-Leadbetter procedures in the treatment of vesicoureteral junction obstruction (VUJO) in children.Methods:The data of 48 children with VUJO who underwent operations in the Department of Urology, Anhui Provincial Children′s Hospital from January 2017 to December 2021 were retrospectively analyzed.According to the operation time, the patients were divided into the pneumovesicoscopic Cohen group(group C) (28 cases) and pneumovesicoscopic Politano-Leadbetter group(group P) (20 cases). The operation time, postoperative urinary catheterization duration, hematuria duration, hospitalization time, and the improvement of hydronephrosis, ureteral dilatation, and renal function after surgery were compared between the 2 groups.The enumeration data were compared by the χ2 test or Fisher′ s exact probability method.The measurement data were compared by the t-test. Results:All the 48 children were successfully operated on by the same surgeon, without conversion to open surgery.Six cases in the group C had a megaureter and underwent ureter tailoring.Two cases in the group P had calyceal and ureteral calculi, which were all removed after operation.There was a statistically significant difference in the operation time between group C and group P[(136.5±35.4) min vs.(165.8±33.2) min, t=-3.154, P=0.002]. The patients were followed up for (10.3±2.6) months after operation.There were 8 cases and 6 cases of urinary tract infection in group C and group P within 2 months after the operation, respectively.They all improved after conservative anti-infection treatment, and the infection was well controlled after removal of the D-J tube.Besides, their intravenous pyelography 6 months after operation showed that the ureter was unobstructed.In group C, 6 months after the operation, the anterior and posterior diameters of the renal pelvis [(1.62±0.54) cm vs.(2.55±1.24) cm, t=-5.027, P=0.001] and the largest diameter of the ureter [(0.95±0.27) cm vs.(1.51±0.52) cm, t=-8.495, P<0.001] were significantly decreased, compared with those before operation.However, the renal cortex thickness was increased significantly [(1.47±0.25) cm vs.(0.86±0.46) cm, t=2.028, P=0.004], and the renal function (as indicated by the diuretic nephrogram) was notably improved [(46.27±2.16)% vs.(41.83±3.04)%, t=1.647, P=0.030]. In group P, 6 months after operation, the anterior and posterior diameters of the renal pelvis[(1.48±0.82) cm vs.(2.68±1.41) cm, t=-2.740, P=0.003] and the maximum diameter of the ureter [(1.05±0.46) cm vs.(1.36±0.27) cm, t=-1.635, P=0.040] were significantly smaller than those before operation.However, the renal cortical thickness was increased [(1.38±0.33) cm vs.(0.74±0.39) cm, t=9.073, P<0.001], and the renal function (as indicated by the diuretic nephrogram) was significantly improved [(45.18±3.35)% vs.(39.55±2.49)%, t=1.277, P=0.030]. Politano-Leadbetter surgery outperformed Cohen surgery in promoting the recovery of the anterior and posterior diameters of the renal pelvis [(1.48±0.82) cm vs.(1.62±0.54) cm, t=-1.748, P=0.030]. Conclusions:Pneumovesicoscopic Politano-Leadbetter operation can establish a longer submucosal tunnel without changing the ureteral shape and opening position, having good effects in treating VUJO combined with calyceal and ureteral calculi.Pneumovesicoscopic Politano-Leadbetter operation can also better improve postoperative recovery from hydronephrosis than Cohen operation.However, the pneumovesicoscopic Politano-Leadbetter operation is more difficult and requires longer time.The surgeon should choose a reasonable operation based on his/her own experience.

Objective: To explore the drug resistance of Isolated From Blood Culture Escherichia coli (E. coli) in a hospital in Qinghai over the past seven years, to evaluate the ability of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) to analyze the homologous origin of E. coli, and to establish a protein fingerprint library to match with it, adjuvant clinical experience medication so as to provide the basis for the prevention and control of hospital-acquired infections. Methods: Retrospective analysis of blood cultures sent to hospitals from January 2016 to December 2022. Drug resistance and resistance changes in E. coli.A total of 1 841 E. coli strains were isolated from Qinghai Provincial People's Hospital from January 2016 to December 2022; all strains were identified by MALDI-TOF MS, and the VITEK2.0 drug sensitivity analyzer was applied for drug sensitivity analysis of the strains, and the mass spectrometry homology analysis and self-constructed protein fingerprint library were carried out by MALDI-Biotyper software; the protein fingerprint library was built by using WHONET5.6 software was used to statistically analyze the drug sensitivity results, SPSS23.0 software was used to analyze the relationship between fingerprint typing and drug sensitivity, and the χ² test was used for intergroup comparisons. Results: A total of 1 841 strains of E. coli were detected in 4 582 positive blood culture specimens from January 2016 to December 2022, with a detection rate of 40.17%; the resistance rate of E. coli from blood sources to piperacillin/tazobactam and ceftriaxone was on the rise, and it was slightly decreased to cefepime, amikacin, levofloxacin, and sulfamethoxazole, and there was not much change to the rest of the drugs; After MALDI-Biotyper clustering analysis, the 1841 E. coli strains from Isolated From Blood Culture were classified into two major clusters and five subtypes, of which type Ⅰa1 accounted for about 40%, type Ⅰa2 accounted for about 2.7%, type Ⅰb accounted for about 3.8, type Ⅱa accounted for about 46%, and type Ⅱb accounted for about 7.5%. The detection rate of type Ⅰa1 E. coli was higher in general surgery (50.45%) and emergency surgery (50.92%), and the detection rate of type Ⅰb E. coli was higher in emergency medicine(10.05%)than in other departments. The drug sensitivity results of different subtypes were compared with each other, the resistance rate of type Ⅰa1 E. coli to cefepime was 21.3% higher than that of the remaining four types, and the difference was statistically significant (χ²=37.74,P=0.000); the resistance rate of type Ⅱ E. coli(>60%) to sulfamethoxazole was higher than that of type Ⅰ (<60%) as a whole, and the difference was statistically significant (χ²=15.248,P=0.004); and a preliminary database of homologous protein fingerprints of E. coli has been established E. coli homologous protein fingerprint library and validated. The drug susceptibility results of 1 288 E. coli strains in the validation set were statistically analyzed and compared with those in the training set. There was no significant difference(P>0.05). Conclusion: In recent years, the resistance rate of E. coli isolated from a hospital in Qinghai province to piperacillin/Tazobactam, cefepime, amicacin and other antibiotics has changed greatly. A fingerprint database of E. coli homologous protein was established, and it was found that the drug sensitivity data of E. coli were different among different fingerprint types. According to drug sensitivity, drug use could assist clinical experience and provide evidence for prevention and control of hospital illness.
