Objective To observe the ultrastructure changes of detrusor of urinary bladder following partial outlet obstruction. Methods 14 New Zealand white male rabbits were divided into "A" and "B" group.The "A" group rabbits underwent operation to induce bladder outlet obstruction,"B" group rabbits served as controls.The ultrastructures including rough endoplactmic reticulum and mitochondrion of detrusor cell of each bladder were examined after 5 weeks. Results The average area of rough endoplactmic reticulum in the obstructed group was (5.377?2.318) ?m 2 in each unit cytoplasm area (115.28 ?m 2) versus (0.476?0.319) ?m 2 in the controls ( P

Objective To evaluate the value of computed tomography(CT)in diagnosing abdominal tuberculosis.Methods CT features of abdominal tuberculosis proven histopathologically or by antituberculous therapy in 16 cases were retrospectively analysed.There were 8 men and 8 women,the age ranged from 20 to 66 years,mean age was 36.4 years.Results The most common CT features of abdominal tuberculosis were:lymphadenectasis(n=11),mesenteric masses(n=6),ascites(n=6,all were loculated),omental thickening(n=7),bowel wall thickening(n=6),pleural fluid(n=2),and pancreatic involvement(n=1).Tuberculous lymphadenosis(mainly the mesentery and peripancreatic lymph nodes involved)had typical CT findings including circular or multilocular enhancement,calcification of lymph nodes,abdominal lymph nodes involved more than that of retroperitoneum and peritonitis(high dense ascites,patchy or nodular lesions in the mesentery and omentum,and intestinal adhesion).Conclusion CT findings in combination with clinical symptoms and laboratory test can improve the diagnosis of abdominal tuberculosis.

OBJECTIVE: To explore the clinical features of acute urine retention (AUR) ocurring in patients with benign prostate hyperplasia (BPH). METHODS: Clinical data from 548 patients diagnosed with BPH were retrospectively studied, and the clinical parameters of these patients with or without AUR were analyzed by statistical methods. RESULTS: Development of AUR was found in 164 patients (29.9%). Patients' age, IPSS, maximum flow rate (Q(max)), residual urine volume, prostate volume, transition zone volume, prostate-specific antigen (PSA) density, total PSA (tPSA) and free PSA (fPSA) including the ratio of free to total PSA(f/tPSA) were significantly different in the 2 groups (P<0.05), while there were no significant differences in the disease duration and transition zone index between the 2 groups (P>0.05). Multivariate logistic regression analysis showed that IPSS score, residual urine volume, tPSA, and Q(max) were risk factors for predicting the development of AUR. CONCLUSION BPH patient's age, IPSS, Q(max), residual urine volume, prostate volume, transition zone volume, tPSA and fPSA, and PSA density all influence the occurrence of AUR, in which symptom severity, residual urine volume, total PSA and Q(max) are the principal risk factors for prognosing AUR.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.
