Objective:To discuss the diagnosis and treatment of urothelial carcinoma of the prostate.Methods:The clinical data of 25 patients with prostate urothelial carcinoma from January 2011 to November 2019 were retrospectively analyzed.Among the 25 patients, the age of onset was 39 to 85 years old, with an average of (63.4±11.2) years old, 13 patient presented with gross hematuria, 9 patients presented with dysuria, and 3 presented with bladder irritation. The PSA of 25 patients was within the normal range (less than 4 ng/ml). 17 cases of pelvic MRI showed abnormal signals in the bladder and prostate area, 3 cases indicated that prostate cancer had invaded the bladder, and 14 cases considered bladder cancer Invasion of the prostate suggests a cauliflower-like abnormal signal in the bladder area. 6 of this 14 patients have a history of bladder cancer. All 25 patients underwent surgical treatment, and 14 underwent transurethral diagnostic resection, of which 6 cases accepted radical cystectomy later. One patient underwent radical cystectomy combined with pelvic lymph node dissection 15 days after the first operation.9 cases received radical cystectomy.2 cases undergoing transurethral palliative resection due to multiple metastases before the operation.Results:The postoperative pathological diagnosis of 25 cases were all prostate urothelial carcinoma, 13 cases were accompanied by bladder urothelial carcinoma, secondary prostate urothelial carcinoma, and 12 cases were primary prostate urothelial carcinoma. After the operation, 13 patients were further treated. Among the patients with secondary prostate urothelial carcinoma, 7 patients received bladder perfusion, 2 patients received GC chemotherapy, 1 patient received local pelvic radiotherapy.25 patients were followed up for 2 to 36 months with an average of (21.5±10.1) months. Among them, lymph node metastasis were seen in 17/25 patients. lymph node metastasis were found in 7/25 before surgery, and 1/25 found lymph node metastasis during surgery. Among the patients with distant metastases afterwards, multiple metastases throughout the body (4/14), lung metastases only (6/14), and bone metastases only (4/14), the 1-year survival rate was 88% (22/25), the 2-year survival rate was 40% (10/25), and the 3-year survival rate was 28% (7/25).Conclusions:The diagnosis depends on histopathological examination. Early diagnosis may help improve prognosis. The first choice is a comprehensive treatment based on radical surgery.

Due to the fact that the articular cartilage of children's joints has not yet been fully ossified, visualizing the adjacent anatomical structures during the clinical diagnosis and treatment of joint diseases and injuries in children is a challenging issue. Arthrography is an efficient, convenient, and minimally invasive technique, and is particularly crucial for the visualization of children's hip joints. Currently, arthrography technology is widely employed during surgeries for developmental dysplasia of the hip (DDH), and in recent years, numerous studies have concentrated on the efficacy of joint angiography, exploring its assessment and predictive roles during and after the operation. We review the overview of hip joint arthrography techniques, such as the concept of arthrography, the selection of access routes for hip joint arthrography, the process of hip joint arthrography, the dosage and operation of contrast agents, and the adverse reactions of contrast agents; the use of hip joint arthrography to evaluate the quality of closed reduction; the use of hip joint arthrography to predict the future development and outcome of the acetabulum after closed reduction; the use of hip joint arthrography in the study of open reduction or osteotomy; the use of hip joint arthrography to observe the morphology of soft tissues in the hip joint; the use of hip joint arthrography in combination with nuclear magnetic resonance to observe the anatomical structure of the acetabular labrum. Summarizing the research results of arthrography for evaluating the corresponding indicators of the hip joint helps improve the matching between the femoral head and the acetabulum and the accuracy of evaluating the quality of reduction, uncovers identifying factors such as labrum varus that hinder concentric reduction, enhances the ability to predict the development and outcome of the acetabulum, and has significant guiding significance for the precise selection of the timing of surgical intervention for early and residual deformities in children with DDH. Exploring the application of arthrography technology in evaluating the quality of closed reduction in DDH and predicting the development of the acetabulum after reduction is expected to provide meaningful references for orthopedic surgeons in the current clinical diagnosis, treatment, and research of DDH.

Objective: To establish a GC determination method for the content and dissolution of magnesium valproate tablets. Methods:Magnesium valproate tablets were detected by a GC internal standard method. The samples were dissolved in 0. 1 mol·L-1 hydrochloric acid solution, and then extracted by dichloromethane. Eicosane was used as the internal standard. The dissolution was de-termined by the first method described in ChP 2015 edition. The dissolution medium was 0. 1 mol·L-1 hydrochloric acid solution and the rotation speed was 100 r·min-1 with the sampling time at 45 min. The samples were extracted by dichiormethane, and eicosane was used as the internal standard as well. Results: The dissolution of magnesium valproate tablets showed good linearity within the range of 0. 005-1. 000 mg·ml-1(r=0. 9999). The recovery was 99. 2% (RSD=0. 5%, n=9). The dissolution curve showed that magnesium valproate released above 80% in 45 minutes. Conclusion:The method has good specificity and high accuracy, and can be used for the content determination and dissolution detection of magnesium valproate tablets.

Single tumor was present in 18 cases, multiple tumors were present in 2 cases. The surgical method was partial cystectomy in 16 cases, radical cystectomy in 1 case, TURBT in 1 case and no operation in 2 cases. There were 32 cases in the non-urachal adenocarcinoma group, including 24 males and 8 females. Their mean age was 55.0(46.3, 70.8) years.11 cases had a history of smoking. The clinic manifestation included hematuria in 16 cases, bladder irritation in 3 cases, dysuria in one case and pain in 7 cases. Tumor located at anterior and posterior walls in 17 cases, at lateral wall in 7 cases, at triangular area in 5 cases and at apical wall in 3 cases. The average diameter of tumor was 3.6(2.0, 4.5) cm. 23 cases suffered with single tumor, 9 cases suffered with multiple tumors.The surgical method was radical cystectomy in 11 cases, partial cystectomy in 9 cases, TURBT in 9 cases , and no operation in 3 cases. The preoperative data of the three groups of tissue types were compared, the differences of age of onset, tumor diameter, tumor location, reason for treatment, operation method ( P<0.05)among the 3 groups were statistically significant. The clinicopathological characteristics and prognosis of the 3 groups of tissue types were compared, and the Cox proportional regression risk model was used to analyze the clinical factors affecting the prognosis. Results:91 patients were followed up, the overall follow-up rate was 85.1%, the median follow-up time was 26(7, 48) months. The 3-year and 5-year overall survival rates were 54.1% and 42.2%, respectively. In the SqCC group, 11 cases received chemotherapy; 3 cases received postoperative radiotherapy; 12 cases received postoperative perfusion.10 cases had recurrence; 17 cases had lymph node metastasis; 19 cases had distant metastasis; 5 cases were pT x in pT stage, 36 cases were pT 1-pT 2, 14 cases were pT 3-pT 4. 19 cases had unknown tumor differentiation, 4 cases had well differentiated, 24 cases had moderately differentiated and 8 cases had poorly differentiated. In the urachal adenocarcinoma group, 7 cases received chemotherapy, 3 cases had recurrence, 2 cases had lymph node metastasis, 2 cases had distant metastasis; 1 case was pT x in pT stage, 16 cases were pT 1-pT 2, 3 cases were pT 3-pT 4. 9 cases had unknown tumor differentiation, 3 cases had well differentiated, and 5 cases had moderately differentiated, 3 cases had poorly differentiated. In the urachal adenocarcinoma group, 3 cases received chemotherapy, 1 case received postradiotherapy, 11 cases received postoperative perfusion; 10 cases had recurrence. 5 cases had lymph node metastasis, 4 cases had distant metastasis, 6 cases were pT x, 21 cases were pT 1-pT 2 and 5 cases were pT 3-pT 4. 14 cases had unknown tumor differentiation, 8 cases had moderately differentiated and 10 cases had poorly differentiated.The postoperative general data of the three groups of tissue types were compared. There was statistically significant difference between whether there was postoperative perfusion and whether there was distant metastasis (all P<0.05). The univariate analysis results showed gender, age, surgical method, lymph node metastasis, distant metastasis, pT staging, tumor differentiation and histological type were risk factors that affect the prognosis(all P<0.05). Cox multivariate analysis showed that women ( HR=2.604, P=0.032) and distant metastases ( HR=2.571, P=0.026) were independent risk factors affecting the prognosis of patients. Conclusions:SqCC and adenocarcinoma are clinically rare and have poor prognosis. They often present with hematuria. Surgical treatment is the first choice. Radical cystectomy is the first choice for SqCC and non-urachal adenocarcinoma, and extended partial cystectomy is the first choice for urachal adenocarcinoma. Female and distant metastasis are independent risk factors affecting the prognosis of patients.

Objective To explore the effects of low-dose esketamine on the median effective dose(ED50)of ciprofol for sedation in elderly patients undergoing ultrasound-guided transperineal prostate biopsy.Methods Forty-nine elderly male patients,aged 65-75 years,BMI 18.5-30.0 kg/m2,ASA physical stutas Ⅰ-Ⅲ,who underwent ultrasound-guided transperineal prostate biopsy,were randomly as-signed into the esketamine-ciprofol group(group E,n=23)and the ciprofol group(group C,n=26).After intravenous administration of sufentanil 0.1 μg/kg,patients in group E received esketamine 0.2 mg/kg,while patients in group C received the same volume of normal saline.The up-and-down sequential allocation method was used to calculate the effective dose of ciprofol.The initial dose of ciprofol was 0.2 mg/kg in group E and 0.3 mg/kg in group C,and the dose gradient was 0.05 mg/kg for both groups.If there was no body movement during the first puncture of prostate after the loss of eyelash reflex,the ciprofol dose in the next patient was reduced by 0.05 mg/kg.Otherwise,the ciprofol dose in the next patient was in-creased by 0.05 mg/kg.The study was completed until 7 inflection points alternating between non-body movement and body movement achieved.The total amount of ciprofol,surgical time,recovery time,stay in recovery room,hypotension,bradycardia,respiratory depression,injection pain,nausea and vomiting,and adverse reaction of the mental system were recorded.The Probit method was used to calculate the ED50 and 95%effective dose(ED95)with 95%confidence interval(CI)of ciprofol for inhibition of body movement.Results Compared with group C,the total amount of ciprofol in group E was significantly reduced(P＜0.05).There were no significant differences between the two groups in surgical time,recovery time,stay in recovery room,and adverse events.The ED50 of ciprofol in group E was 0.22 mg/kg(95%CI 0.19-0.26 mg/kg),and the ED50 in group C was 0.38 mg/kg(95%CI 0.31-0.46 mg/kg).Compared with group C,the ED50 in group E was significantly reduced(P＜0.05).The ED95 of ciprofol in group E was 0.28 mg/kg(95%CI 0.25-0.49 mg/kg),and the ED95 in group C was 0.51 mg/kg(95%CI 0.44-1.25 mg/kg).Compared with group C,the ED95 in group E was significantly reduced(P＜0.05).Conclusion The ED50 of ciprofol for inhibition of body movement in elderly patients undergoing ultrasound-guided transperi-neal prostate biopsy was 0.38 mg/kg,which was reduced to 0.22 mg/kg by using lose-dose esketamine 0.2 mg/kg as an adjuvant.

BACKGROUND:Establishing a nomogram prediction model for postoperative pulmonary infection in hip fractures and taking early intervention measures is crucial for improving patients'quality of life and reducing medical costs. OBJECTIVE:To construct a nomogram risk prediction model of postoperative pulmonary infection in elderly patients with hip fracture,and provide theoretical basis for feasible prevention and early intervention. METHODS:Case data of 305 elderly patients with hip fractures who underwent surgical treatment at Wuxi Traditional Chinese Medicine Hospital Affiliated to Nanjing University of Chinese Medicine between January and October 2020(training set)were retrospectively analyzed.Using univariate and multivariate logistic regression analysis and Hosmer-Lemeshow goodness of fit test,receiver operating characteristic curve was utilized to analyze the diagnostic predictive efficacy of independent risk factors and joint models for postoperative pulmonary infections.Tools glmnet,pROC,and rms in R Studio software were applied to construct a nomogram model for predicting the risk of postoperative pulmonary infection in elderly patients with hip fractures,and calibration curves were further drawn to verify the predictive ability of the nomogram model.Receiver operating characteristic curves,calibration curves,and decision curves were analyzed for 133 elderly patients with hip fractures(validation set)receiving surgery at the same hospital from November 2022 to March 2023 to further predict the predictive ability of the nomogram model. RESULTS AND CONCLUSION:(1)The postoperative pulmonary infection rate in elderly patients with hip fractures in this group was 9.18%(28/305).(2)Single factor and multivariate analysis,as well as forest plots,showed that preoperative hospitalization days,leukocyte count,hypersensitive C-reactive protein,and serum sodium levels were independent risk factors(P<0.05).The Hosmer-Lemeshow goodness of fit test showed good fit(χ2=4.57,P=0.803).Receiver operating characteristic curve analysis was conducted on the independent risk factors and their joint models mentioned above,and the differentiation of each independent risk factor and joint model was good,with statistical significance(P<0.05).(3)The graphical calibration method,C-index,and decision curve were used to validate the nomogram prediction model.The predicted calibration curve was located between the standard curve and the acceptable line,and the predicted risk of the nomogram model was consistent with the actual risk.(4)The validation set used receiver operating characteristic curve,graphic calibration method,and decision curve to validate the prediction model.The results showed good consistency with clinical practice,indicating that the model had a good fit.The nomogram risk prediction model constructed for postoperative pulmonary infection in elderly patients with hip fractures has good predictive performance.The use of the nomogram risk prediction model can screen high-risk populations and provide a theoretical basis for early intervention.

BACKGROUND:The alteration of miR-146a-3p level is a common event in the pathogenesis of most neurological diseases,and the specific mechanism of miR-146a-3p regulation of astrocytes has not been studied. OBJECTIVE:To verify that miR-146a-3p regulates astrocyte proliferation,migration and apoptosis through insulin-like growth factor 1. METHODS:12 SD rats were divided into a sham operation group and a spinal cord injury group,with six rats in each group.RNA sequencing analysis was performed on the spinal cord tissues of all groups 2 weeks after surgery to screen out the differential genes(log2FC>2),and to select spinal cord injury-related genes(Score>20)in the Genecards database,and then to predict the target genes of miR-146a-3p by Targetscan.The intersection of three gene sets was obtained to screen out insulin-like growth factor 1 as one of the important target genes.qPCR,western blot assay and immunohistochemistry were performed to analyze the expression level of insulin-like growth factor 1 in spinal cord tissues.The primary astrocytes were divided into NC group,NC-mimics group and miR-146a-3p mimics group.Annexin-V/PI staining was used to detect cell apoptosis.CCK-8 assay was used to detect cell proliferation.Transwell assay was used to detect cell migration ability. RESULTS AND CONCLUSION:The expression of miR-146a-3p in the spinal cord tissue of the spinal cord injury group was lower than that of the sham operation group(P<0.05).The expression of insulin-like growth factor 1 in the spinal cord tissue of the spinal cord injury group was higher than that of the sham operation group(P<0.05).Compared with the NC group and NC-mimics group,the apoptotic rate of astrocytes was increased(P<0.01);the proliferation of astrocytes was decreased(P<0.01)and the number of migration was decreased(P<0.01)in the miR-146a-3p mimics group.To conclude,the expression of miR-146a-3p decreased and the expression of insulin-like growth factor 1 increased in spinal cord tissue after spinal cord injury.miR-146a-3p targeted regulation of insulin-like growth factor 1 in astrocytes,inhibited the proliferation and migration of astrocytes and promoted their apoptosis.

In terms of alternative suggestion, 70.74%(162/229) of surgeons believed that it was necessary for the We-Media platforms to involve more doctors of different specialties, but 40.61%(93/229) of surgeons believed that relevant departments or associations should strengthen supervision under the current situation. In addition, 32.75%(75/229) of surgeons believed that the operation of We-Media platform requires more investment. The were 27.95%(64/229) of surgeons giving specific suggestions on running We-Media platforms, 7.81%(5/64) of which did not suggest a blind try.Conclusions:Most surgeons who open and operate We-Media platforms in China are faced with problems such as busy work, limited time and energy, low-income increase, and lack of professional promotion and maintenance teams and external support. Even so, there are still many surgeons who have achieved success through long-term persistence and high-quality content output, thus increasing the number of patient visits, improving their own ability and industry influence, and bringing a greater sense of professional achievement.
