Objective To evaluate the clinical application of CT virtual cystoscopy (CTVC). Me-thods Thirteen patients who had clinical indication were studied. Iodine contrast was intravenously injected after the bladder was voided. Thin-slice spiral CT scanning of the bladder area was started when the bladder became filled with contrast media. By using 3D navigator smooth software, CTVC images were obtained. The findings in all cases were compared with the cystoscopy and surgical results. Results Nine patients with CTVC were proved vesical tumor,3 patients with CTVC were proved benign prostatic hyperplasia, and they were confirmed by cystoscopy,1 patient with cystitis glandularis could not be diagnosed with CTVC.By CTVC, the diagnostic accordance rate was 92.3%,the coincidence rate was 100.0% in vesical tumor. Conclusions CTVC is highly sensitive in displaying the vesical lesions.Being a new and non-invasive technique, CTVC is very helpful in the diagnosis of introvesical diseases. It has fine value in the clinical practice.

Objective To investigate the quality of life in man after treatment of advanced prostate cancer by surgical castration. Methods A total of 69 patients with advanced prostate cancer treated by sur-gical castration completed the European organization for research and treatment of cancer quality of life questionnaire (QLQ-C30) and QLQ-prostate specific 25-item (PR25) module third at a 12-month interval.The assessment points were preoporative,6 months postoperative and 12 months postoperative. Results Although there were improvement on pain relief (P ＜ 0.01 ) and symptom of urinary (P ＜ 0.01 ) and global health (P ＜ 0.01 ), the physical functioning (P ＜ 0.05 ), role functioning (P ＜ 0.01 ), emotional functioning (P ＜ 0.01 ), cognitive functioning (P ＜ 0.05 ), social functioning (P ＜ 0.05 or ＜ 0.01 ) were found significantly reduced , and insomnia (P ＜ 0.05) and fatigue (P ＜ 0.01 ) aggravated, treatment related symptoms (P ＜0.01 )appeared predominantly, especially deprivation of sexual functioning. Conclusion The surgical cas-tration when treating advanced prostate cancer did appear to impair the physical and psychological of patients, especially the sexual functioning.

Background::Data on the glycemic profile of pregnant women with gestational diabetes mellitus (GDM) during the perinatal period are sparse. This study described the intrapartum and early postpartum glucose profiles among pregnant women with GDM, and analyzed factors potentially affecting glycemic parameters during the period.Methods::This was a prospective observational study conducted from March 2020 to November 2021. Pregnant women with GDM receiving lifestyle interventions alone during pregnancy and matched women with non-diabetic pregnancies (NDPs) were enrolled from among patients admitted to the obstetrics department for childbirth. Glucose monitoring was performed via a flash glucose monitoring (FGM) system on admission, and glucose readings during labor and early postpartum were analyzed. The clinical characteristics and FGM-based parameters of participants in the two groups were compared.Results::A total of 124 participants (mean age: 29.5 ± 3.5 years, 92 [74.2%] primipara) were included in the final analysis. A total of 17,571 glucose readings were retrieved. There were no significant differences in clinical characteristics between the GDM ( n = 60) and NDP ( n = 64) groups. The average glucose level was 92.2 mg/dL, and the level was higher in the GDM group (95.5 ± 12.1 mg/dL vs. 89.1 ± 13.4 mg/dL, P = 0.008) during the intrapartum and early postpartum periods. The data were split into the intrapartum period (from the start of labor to delivery of the placenta) and the early postpartum period (within 24 h after placental delivery) for analysis. During intrapartum, women with GDM exhibited glycemic profiles and fluctuations similar to those in the NDP group. However, women with GDM had higher postpartum glucose levels (97.7 ± 13.4 mg/dL vs. 90.8 ± 15.3 mg/dL, P = 0.009), a longer time spent >140 mg/dL (8.7 ± 9.3% vs. 5.9 ± 10.3%, P = 0.011), and greater glycemic fluctuations than those with NDP. Postpartum hyperglycemia in GDM might be associated with high parity and postprandial glucose abnormalities in GDM screening tests. Conclusion::Compared to those with normoglycemia, pregnant women with GDM receiving lifestyle interventions alone had similar intrapartum glucose profiles but higher early postpartum glucose levels and greater glucose variability, providing evidence for modification of the current perinatal glucose monitoring strategy for GDM.Trial Registration::ChiCTR.org.cn, ChiCTR2000030972

Objective To analyze and summarize the clinical presentation of spontaneous and secondary intracranial hypotension syndrome(IHS).Methods Patients diagnosed with spontaneous or secondary IHS from September 2022 to May 2023 were retrospectively analyzed.The clinical data,imaging features,treatment methods and prognosis were collected.The correlation between intracranial pressure values and clinical characteristics of the patients was statistically analyzed.Results A total of 30 patients were enrolled,and the proportion of spontaneous and secondary IHS was 63%(19 cases)and 37%(11 cases),respectively.In terms of clinical features,orthostatic headache was the most common type(29 cases,96.7%)and most commonly involved occipital region(12 cases,40.0%),followed by frontoparietal region(9 cases,30.0%).Among the brain imaging features,dural enhancement was the most common(17 cases,56.7%).According to CT angiography of spinal cord findings,cerebrospinal fluid leakage is one of the most common location of cervical spine segments(10 cases),and on the thoracic segments(9 cases),followed by the thoracic segments(4 cases)and lumbar segments(4 cases).After conservative treatment and surgical treatment,the total effective rate was 90%.Conclusion Orthostatic headache and cranial MRI"dural enhancement"have strong indication on the definitive diagnosis of IHS.CT myelography is helpful to precisely localize the site of cerebrospinal fluid leakage.Targeted epidural blood patch therapy is an effective method to cure IHS when conservative treatment is ineffective.

To provide a theoretical basis for controlling the spread of rust disease, cultivating disease-resistant varieties and reducing yield losses, we investigated the transcriptome differences between Gymnosporangium yamadae and Gymnosporangium asiaticum at the haustorial stage and revealed a specialized selection mechanism for Gymnosporangium species to infect host plants. We sequenced the transcriptomes of the haustoria in rust-infected leaves when basidiospores of G. yamadae and G. asiaticum infected their hosts, and obtained 21 213 and 13 015 unigenes, respectively. Real-time fluorescence quantitative PCR validation of five genes selected from G. yamadae and G. asiaticum, respectively, showed that their expression profiles were generally consistent with the results of transcriptome analysis, demonstrating the reliability of the transcriptome data. We used seven databases such as Nr, GO, KEGG, and KOG to perform gene function annotation and enrichment analysis, and found that the genes from both rusts were mainly enriched in cellular processes, translation, and metabolism-related pathways. Moreover, we used SignalP, TMHMM online website and other software such as dbCAN, BLSAT, HMMER to show that there were 343 (2.51%) and 175 (2.79%) candidate effector proteins containing 14 and 5 proteases and 10 and 3 lipases in the haustoria of G. yamadae and G. asiaticum, respectively. Furthermore, we used OrthoFinder, BLAST and KaKs Calculator software to analyze the evolutionary relationship of the two fungi. Among one-to-one homologous genes, gene pairs with > 82% alignment were considered to be under conservative selection, and 12.37% under positive selection. Five effectors of G. asiaticum were under positive selection, and one of which was a lipase. No significant differences were found in the enrichment of expressed genes between G. yamadae and G. asiaticum, indicating the biological processes involved in haustoria were relatively conserved, despite the typical host selectivity between species. The low protein similarity between the two species suggested that they were under greater host selective pressure and there was significant evolutionary divergence, which might be related to the host-specific selection mechanism. In the haustorial, the main purpose of the effectors might be to regulate physiological processes in the plants rather than attacking the host directly, and G. yamadae and G. asiaticum might use plant lipids as energy sources.
