Objective To explore the advantages and disadvantages of transvaginal hysterectomy for patients with non-prolapsed uterus,and explore the cause and preventive measurements of the complications of transvaginal hysterectomy.Methods The complications of transvaginal hysterectomy ( group TVH ) in 110 patients with non-prolapsed uterus and of transabdominal hysterectomy ( group TAH ) in 120 patients were compared with each other.These patients were chosen randomly from June 2006 to April 2010.Results In the TVH group,rectum hurt occurred in one patient,prolapse of fallopian tube in one patient and celiac internal bleeding in one patient.The preoperative diagnosis were not consistent with the postoperative diagnosis in four patients.Two patients encountered with postoperative residual end bleeding and four patients with vaginal residual end polyps.In the TAH group,three patients had postoperative diagnosis inconsistent with their preoperative diagnosis.In addition,there were four abdominal wall incision liquefaction ( including two phase suture in two patients),three postoperative bronchial lung infection and two residual end polyps.No celiac internal bleeding and visceral injury occurred in this group.Conclusion TVH has a higher risk of visceral injury and postoperative bleeding than TAH.These complications should be avoided when treating the patients with TVH technique.

OBJECTIVE：To investigate t he effects of Baihe gujin decoction combined with Shenmai injection on therapeutic efficacy and related indexes in elderly patients with ventilator-associated pneumonia. METHODS ：A total of 75 elderly patients with ventilator-associated pneumonia who were admitted to the Intensive Care Unit （ICU）of Zhuji Hospital of TCM from Apr. 2018 to Oct. 2019 were included. They were randomly divided into control group ，Shenmai group ，Baihe gujin decoction+Shenmai group ， with 25 cases in each group. Control group was given conventional treatments as Piperacillin sodium tazobactam sodium injection 4.5 g，ivgtt，q8 h for anti-infective treatment+ Ambroxol hydrochloride injection 4 mL，iv，bid for expectorant+ Doxofylline injection 20 mL，qd for relieving spasm and asthma+maintaining water ，electrolyte and acid-base balance. Shenmai group was given Shenmai injection 100 mL，ivgtt，qd，on the basis of control group. Baihe gujin decoction+Shenmai group was given Baihe A101） gujin decoction 200 mL nasally ， morning and evening ，on m the basis of Shenmai group. Each group took 7 days as a course of treatment ，and the treatment was continued for 2 courses. Acute physiology and chronic health status （APACHE）Ⅱ score，C-reactive protein （CRP）in peripheral blood ，procalcitonin（PCT），bronchial CD 68 count were observed in 3 groups before and after treatment while the mechanical ventilation time ，hospitalization time in the ICU and ADR recorded. RESULTS：Before treatment ，there was no statistically significant difference in APACHE Ⅱ score，the levels of CRP and PCT ， bronchial CD 68 count among 3 groups（P＞0.05）. After 14 days of treatment ，APACHE Ⅱ score，CRP and PCT levels of all 3 groups were significantly lower than before treatment ；bronchial CD 68 count was significantly higher before treatment ，the order of bronchial CD 68 cell count was Baihe gujin decoction+Shenmai group ＞Shenmai group ＞control group （P＜0.05 or P＜0.01）；after 7 days of treatment ，the order of CRP and PCT levels was Baihe gujin decoction+Shenmai group ＜Shenmai group ＜control group （P＜0.05）；after 14 days of treatment ，there was no staistically significant difference in APACHE Ⅱ score，CRP and PCT levels among 3 groups（P＞0.05）. After treatment ，the order of mechanical ventilation time and ICU hospitalization time was Baihe gujin decoction + Shenmai group ＜Shenmai group ＜control group （P＜0.05 or P＜0.01）. There was no significant difference in the incidence of ADR among 3 groups（P＞0.05）. CONCLUSIONS ：Based on routine treatment ，Baihe gujin decoction combined with Shenmai injection can improve the immune function of lung macrophages in the elderly patients with ventilator-associated pneumonia，inhibite pulmonary inflammation progress ，reduce mechanical ventilation time ，shorten the length of hospital stay with good safety.

Objectives:To investigate the value of metagenomic next-generation sequencing (mNGS) in the diagnosis of Pneumocystis jirovecii pneumonia (PJP) in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) .Methods:The data of 98 patients with suspected pulmonary infection after allo-HSCT who underwent pathogen detection from bronchoalveolar lavage fluid between June 2016 and August 2023 at Nanfang Hospital were analyzed. The diagnostic performance of mNGS, conventional methods, and real-time quantitative polymerase chain reaction (qPCR) for PJP were compared.Results:A total of 12 patients were diagnosed with PJP, including 11 with a proven diagnosis and 1 with a probable diagnosis. Among the patients with a proven diagnosis, 1 was positive by both conventional methods and qPCR, and 10 were positive by qPCR only. Pneumocystis jirovecii was detected by mNGS in all 12 patients. The diagnostic sensitivity of mNGS for PJP was 100%, which was greater than that of conventional methods (8.3%, P=0.001) and similar to that of qPCR (91.6%, P=1.000) . A total of 75% of the patients developed mixed pulmonary infections, and cytomegalovirus and Epstein-Barr virus were the most common pathogens. Mixed infection was detected in eight patients by mNGS and in five patients by qPCR, but not by conventional methods ( P=0.008) . Conclusions:mNGS had good sensitivity for diagnosing PJP after allo-HSCT and was advantageous for detecting mixed infectious pathogens; therefore, mNGS might be an effective supplement to regular detection methods and qPCR.

Liver is the central hub regulating energy metabolism during feeding-fasting transition. Evidence suggests that fasting and refeeding induce dynamic changes in liver size, but the underlying mechanisms remain unclear. Yes-associated protein (YAP) is a key regulator of organ size. This study aims to explore the role of YAP in fasting- and refeeding-induced changes in liver size. Here, fasting significantly reduced liver size, which was recovered to the normal level after refeeding. Moreover, hepatocyte size was decreased and hepatocyte proliferation was inhibited after fasting. Conversely, refeeding promoted hepatocyte enlargement and proliferation compared to fasted state. Mechanistically, fasting or refeeding regulated the expression of YAP and its downstream targets, as well as the proliferation-related protein cyclin D1 (CCND1). Furthermore, fasting significantly reduced the liver size in AAV-control mice, which was mitigated in AAV Yap (5SA) mice. Yap overexpression also prevented the effect of fasting on hepatocyte size and proliferation. Besides, the recovery of liver size after refeeding was delayed in AAV Yap shRNA mice. Yap knockdown attenuated refeeding-induced hepatocyte enlargement and proliferation. In summary, this study demonstrated that YAP plays an important role in dynamic changes of liver size during fasting-refeeding transition, which provides new evidence for YAP in regulating liver size under energy stress.
