Objective:To investigate the clinical efficacy and safety of amisulpride in the treatment of schizophrenia.Methods:Ninety patients with schizophrenia admitted to Quzhou Third Hospital from August 2020 to March 2022 were included in this study. They were randomly divided into an observation group and a control group ( n = 45/group). The control group was treated with olanzapine, and the observation group was treated with amisulpride. All patients were treated for 8 consecutive weeks. Total response rate, Positive and Negative Syndrome Scale score, Clinical Global Impression Scale-Severity of Illness score, glucose and lipid metabolism indicators, Treatment Emergent Symptom Scale score, and adverse reactions were compared between the two groups. Results:Total response rate was 88.89% (40/45) in the control group and 93.33% (42/45) in the observation group. There was no significant difference in total response rate between the two groups ( χ2 = 0.14, P > 0.05). After treatment, the PANSS score [(52.14 ± 3.99) points] and CGI-S score [(3.05 ± 0.86) points] in the observation group were significantly lower than (56.38 ± 4.05) points and (4.34 ± 0.92) points in the control group ( t = 5.00, 6.87, both P < 0.001). The levels of fasting plasma glucose [(5.25 ± 0.33) mmol/L], total cholesterol [(4.08 ± 0.67) mmol/L], triglyceride [(1.29 ± 0.35) mmol/L], and low density lipoprotein-cholesterol [(2.60 ± 0.31) mmol/L] in the observation group were significantly lower compared with the control group [(6.02 ± 0.51) mmol/L, (4.71 ± 0.59) mmol/L, (1.61 ± 0.26) mmol/L, (2.91 ± 0.34) mmol/L, t = 8.50, 3.61, 4.92, 4.52, all P < 0.001]. High density lipoprotein-cholesterol level in the observation group was significantly higher than that in the control group [(1.57 ± 0.36) mmol/L vs. (1.18 ± 0.42) mmol/L t = -4.73, P < 0.001]. Treatment Emergent Symptom Scale score in the observation group was significantly lower than that in the control group [(2.39 ± 0.58) points vs. (2.87 ± 0.62) points, t = 3.79, P < 0.05]. The incidences of drowsiness [6.67% (3/45)], constipation [8.89% (4/45)], and weight gain [2.22% (1/45)] in the observation group were significantly lower than those in the control group [73.33% (33/45), 28.89% (13/45), 17.78% (8/45), χ2 = 4.14, 4.64, 4.44, P < 0.05]. Conclusion:The efficacy of sulfapride in the treatment of schizophrenia is equivalent to that of olanzapine. Sulfapride is better than olanzapine in improving symptoms and reducing disease severity and has better safety.
摘要
For a long time, urological surgeons have been troubled by the treatment of long proximal and mid ureteral stricture, and the commonly used ileal ureteral substitution and autotransplantation have certain shortcomings. In recent years, the development of autologous graft technique has brought a new hope for these patients. The commonly used autologous grafts or flaps include oral mucosa, intestinal tissue, urogenital tissue, etc. The feasibility and safety of autologous graft technique have been preliminarily verified, but each kind of graft or flap has different advantages and disadvantages. The research progress of autologous grafts or flaps ureteroplasty in this article was reviewed and the related problems of this technique were discussed.

Objective:To study the clinical manifestations and treatment of neonatal testicular torsion (NTT) and to summarize the experience of diagnosis and treatment.Methods:The clinical data of the patients with NTT admitted to the Department of Pediatric Urology in Guangzhou Women and Children's Medical Center from January 2015 to January 2021 were analyzed retrospectively. The data included demographic information, testicular torsion duration, clinical presentation, ultrasonography findings, surgical procedures, pathological results, follow-ups, and prognosis.Results:A total of 17 cases were enrolled in this study, and the median age was 5.2 d, ranging from 1 d to 17 d; the weight ranging from 2 800 g to 4 000 g. 11 cases of left testicular torsion and 6 cases of right testicular torsion. The median time from onset to medical attention was 3.8 d, ranging from 10 h to 15 d. The first manifestations being reported were scrotal swelling, color change, or painless mass. Emergency ultrasound revealed that the blood flow signal in the testis was significantly reduced or disappeared, and heterogeneous mass echoes were detected in the scrotum. Surgical exploration was performed in all 17 cases and confirmed to be testicular torsion. There were 15 cases of extravaginal torsion and 2 cases of intravaginal torsion. There were 6 cases of clockwise torsion and 11 cases of anticlockwise torsion. The average degree of twisted testis was 450.8°, ranging from 270° to 720°. The rate of orchiectomy was 88.2% (15/17). All patients were followed up for a minimum of 1 year postoperatively. None of the patients experienced postoperative bleeding or infection at the scrotal incision site. There were no instances of recurrent testicular torsion, and the contralateral testicles showed no abnormalities. In 2 cases where the affected testicle was preserved, ultrasound reevaluation at 6 months postoperatively revealed atrophy of the affected testicle.Conclusions:NTT is rare in clinics and lacks specificity, with a high rate of testis loss. When the newborns exhibit scrotal swelling, color change, or other abnormalities, testicular torsion cannot be ruled out, and early surgical exploration is required.

Objective:Objectives The aim of the study is to evaluate the mechanical performance, safety and efficacy of the novel robotic-assistant flexible ureteroscopy system (Ra-fURS) under in vitro and in vivo environments.Methods:Combing with commercial flexible ureteroscopes, the novel Ra-fURS was used for the in vitro test and animal model operation in October 2020. The study included three sections. ①Basic mechanical performance assessment: including endoscope motion control (dual deflection, axial rotation and forward/backward distance), reaction time and fiber regulation. ②Simulated surgery in ex-vivo 3D-printing renal collecting system model: including completion rate and time of calyxes exploration, directional movement and laser fragmentation [gypsum models (0.5×0.5×0.5 cm) were used to stimulate kidney stones]. ③Intrarenal surgeries in animal models (two 5-month female Yorkshire white pigs). In total, 32 surgeries was performed (8 surgeons × 2 pigs × 2 kidneys/pig). In vivo assessments were carried out including: ①consuming time for Ra-fURS installation and offloading; ②completion rate and time of calyxes exploration; ③comfort score (ranging from 0-10) as compared to the manual f-URS, which was corresponding to each Ra-fURS surgery. In simulated surgery and animal surgery sections, 8 surgeons were enrolled in the study (group A 4 without flexible ureteroscopy experience; group B: 4 highly experienced), and results were compared between two groups.Results:Under the Ra-fURS control, the flexible ureteroscope movement in three degrees of freedom (forward / backward: + 11 to -11 cm, axial rotation + 225°to -225°; active duel-flection: + 270°to -270°, as well as the laser fiber regulation + 2.5 to -2.5 cm). In simulated surgery tests, both groups achieved 100% completion rate of calyxes exploration, and there were no statistical differences in the time of the calyxes exploration between group A and group B (116.0±8.0)s vs.(110.3±15.4)s( P>0.05). Time-consumption for laser fragmentation of group B was shorter than that of group A (525.8±58.5)s vs. (780.5±141.2)s( P<0.01). In animal surgery, the installation time of Ra-fURS gradually shortened within the first 7 cases was(234.0±43.0)s, and became comparable in the later 8-32 cases was(149.3±8.0)s. The average uninstall time was (43.9 ±5.9)s and was relatively stable. There were 51 renal calyxes in two pigs. It was higher for the completion rate of calyxes exploration in group B than in group A [(95.5±9.1)% vs. (59.1±9.1)%, P<0.05], and the exploration time was also statistically variant between the two groups group A and group B[(274.8±34.6)s vs.(127.3±18.2)s, P<0.05]. For all the operators, the comfort scores were favorable to the Ra-fURS as compared to the manual f-URS (8.9±0.3 vs. 5.9±1.1, P<0.05). Conclusions:This preliminary study demonstrated that the novel Ra-fURS was capable of controlling flexible ureteroscope to perform retrograde intrarenal surgery and fragmenting stones with laser. Besides, other features, including easy installation, stable performance and comfortable manipulating environment, made it easy to use in clinical application.
摘要
The fracture risk of patients with diabetes is higher than those of patients without diabetes due to hyperglycemia, usage of diabetes drugs, changes in insulin levels, and excretion, and this risk begins as early as adolescence. Many factors including demographic data (such as age, height, weight, and gender), medical history (such as smoking, drinking, and menopause), and examination (such as bone mineral density, blood routine, and urine routine) may be related to bone metabolism in patients with diabetes. However, most of the existing methods are qualitative assessments and do not consider the interactions of the physiological factors of humans. In addition, the fracture risk of patients with diabetes and osteoporosis has not been further studied previously. In this paper, a hybrid model combining XGBoost with deep neural network is used to predict the fracture risk of patients with diabetes and osteoporosis, and investigate the effect of patients' physiological factors on fracture risk. A total of 147 raw input features are considered in our model. The presented model is compared with several benchmarks based on various metrics to prove its effectiveness. Moreover, the top 18 influencing factors of fracture risks of patients with diabetes are determined.

Objective:To explore the relationship between smoking and the effect of antipsychotics in schizophrenics.Methods:From July 2017 to July 2019, 142 schizophrenics in the mental health center were treated with olanzapine, and the serum drug concentration and concentration/dose ratio (C/D) were calculated.The age, sex, liver function, smoking, combined medication and other clinical data of the two groups were collected, and the influencing factors of serum olanzapine concentration in schizophrenic patients were analyzed by multivariate logistic regression.Results:Forty-four patients were in the non-compliance group(serum olanzapine concentration <20ng/mL), and 98 patients were in the compliance group(serum olanzapine concentration 20-80ng/mL). In the non-compliance group, males accounted for 72.2%, the average age was (61.6±10.5)years old, smoking history accounted for 90.1%, and serum C/D was (2.5±1.1)ng·mL -1·mg -1·d -1, and in the compliance group, males accounted for 51.0%, the average age was (57.9±9.6)years old, smoking history accounted for 41.8%, and serum C/D was (3.2±1.8)ng·mL -1·mg -1·d -1, and there were statistically significant differences in sex, age, smoking history and serum C/D between the two groups ( t=5.86, χ 2=2.06, χ 2=5.43, t=2.38, all P<0.05). Multivariate logistic regression analysis showed that smoking and CYP1A2 genes were independently related to whether the plasma concentration of olanzapine was up to standard in schizophrenic patients.Compared with non-smokers, previous smoking increased the probability of blood concentration non-compliance by 11% and current smoking by 15% respectively( OR=1.15, P=0.001). And compared with CYP1A2 gene AA, CYP1A2 gene AC reduced the probability of blood concentration non-compliance by 15% and CYP1A2 gene CC by 13%( OR=0.87, P=0.002). Conclusion:There is an independent correlation between smoking and serum C/D value of olanzapine in schizophrenics.Quitting smoking can reduce the probability of substandard blood concentration.

Objective To assess the efficacy and safety of oral fosfomycin trometamal in patients with lower urinary tract infections ( UTIs) caused by multi drug resistant ( MDR) bacteria in the clinical setting in China.Methods Multicenter study was conducted from January 2011 to December 2011 in 12 hospitals in China.Three hundred and fifty-six patients with non-fever lower UTls were treated by fosfomycin trometamal 3 g once daily.Three hundred and fifty cases with complete data were further evaluated .One hundred and twenty ( 34.3%) were male and 230 ( 65.7%) were female.The average age was ( 49.9 ± 16.6) years.Depending of the results of urine culture at the first visit ,142 patients with E.coli, Klebsiella pneumonia, proteus, Staphylococcus aureus, Staphylococcus epidermidis and entercocous were analyzed.The susceptibility of MDR bacteria to fosfomycin trometamol were calculated . The clinical efficacy , bacteriological efficacy of fosfomycin trometamol to these patients was evaluated .Results For the gram-negative bacteria detected by culture , among the E.coli, Klebsiella pneumonia and proteus, 50%(52/104) were Extended-Spectrum β-lactamases producing organisms . For the gram-positive bacteria ( n =38 ) detected by culture, methicillin-resistant staphylococcus accounts for 55%(11/20) of all the Staphylococcus and the other gram-positive bacteria were Enterococcus ( n=18 ) .Higher susceptibility rates to fosfomycin trometamol were observed among MDR bacteria (85.7%) and the clinical effective rate and bacteriological effective rate of fosfomycin trometamol were 96.4%( 53/55 ) and 87.5%( 42/48 ) , respectively .The incidence of drug-related adverse events (AEs) was 5.6%(20/356).The most common AE was diarrhea. No drug-related serious adverse events were found .Conclusions The distributions of uropathogens in China are complicated. The detection rate of MDR uropathogens is high . The dosing regimen of fosfomycin trometamal 3 g once daily is effective and tolerable for the patients with lower UTIs caused by MDR bacteria . It may represent good options for the empiric therapy for the patients with lower UTIs .

Objective To evaluate the efficacy and safety of the flexible ureteroscopy (FURS) with holmium laser lithotripsy in the management of stones in ectopic pelvic kidney (PK).Methods We retrospectively reviewed the records of 11 patients,ranged from 37-52 years old,who were underwent FURS with holmium laser for PK stones from January 2007 to April 2012.Three cases had solitary stones in renal pelvis,3 cases had solitary stones at lower calyx and multiple stones were found in 5 cases.Mean size of stone was 2.3 cm (ranged 1.8-3.7 cm).One case had history of ESWL and PCNL before surgery with unsatisfied result and 7 cases were underwent ESWL with poor outcome.The double J stent was placed into the ureter two weeks before the operation.Under the general anesthesia,the ureteral access sheath was placed firstly during operation.Then,flexible ureteroscopy was inserted into the renal pelvis through ureteral access sheath.Holmium laser was used to perform the procedure with the power less than 20 W (0.6-1.0 J/10-20 Hz).The stone fragments were taken out by stone baskets and double-J stent was set at the end of the procedure for additional two weeks.Results The successive rate of the ureteroscopic insertion was 100％.The average operation time was 62 min (ranged 31-87 min).No severe complications such as heavy bleeding,perforation or ureteral avulsion occurred.Small stone fragments were found in 3 cases.All of them located in the lower calyx.Since no one complained about the upper urinary obstruction or related symptoms,conservative observation was considered.All patients discharged the day after the operation.Within three months follow-up,no sign of urinary obstruction was found.Conclusions FURS with holmium laser is a safe,effective and minimally invasive technique.It could be the best option in the management of renal calculi in ectopic pelvic kidney.

Clinical trials are important means to push forward the development of human health. Every new drug needs to under-take clinical trials eventually to determine the efficacy and safety. In the paper, through our clinical trial experiences and extensive lit-erature retrieval, some problems of the communication management in clinical trials were analyzed and relevant countermeasures were suggested to improve the communication management in clinical trials in order to help the development of clinical trials.
