Objective To evaluate the clinical application of vaginal hysterectomy. Methods Clinical data of 118 patients with benign uterine diseases treated by vaginal hysterectomy (Vaginal Group) were retrospectively reviewed and were compared with those of 124 patients who underwent open hysterectomy (Open Group). Results The operative time (50 1 min?15 3 min), the intraoperative blood loss (150 4 ml?56 ml), the number of patients with a need for postoperative analgesics (26 cases), the postoperative pyrexia (42 cases), the time to first getting out of bed (26 4 h?6 3 h) and the length of hospitalization (5 2 d?1 2 d) in the Vaginal Group were significantly less than those in the Open Group (70 3 min?12 4 min, 212 2 ml?70 3 ml, 124 cases, 94 cases, 48 5 h?12 1 h, 8 2 d?2 2 d, respectively; P =0 000). There were no statistical significances between the two groups in occurrence of intra- or post- operative complications (Vaginal Group: 0 8%, 1/118, Open Group: 5 6%, 7/124; ? 2=2 982, P =0 084). Conclusions Vaginal hysterectomy has the advantages over open hysterectomy in minimal invasion and rapid recovery.

This study was aimed to provide a reference for the development, registration, and clinical use of hospital traditional Chinese medicine (TCM) preparations, in order to analyze and assess their safety and risk. It also provided a reference for the technical review and supervision of hospital TCM preparations. Through collecting review materials of hospital TCM preparations from 2012 to 2014 in the Sichuan Food and Drug Administration, 21 preparations developed by clinical experiences were screened out. Analysis was made on their ingredients, preparation process and acute toxicity data. The results showed that 98 kinds of Chinese herbal medicines were contained in 21 preparations. The dosages of herbs were in compliance with theChina Pharmacopoeia2010 Edition. Preparation processes of 16 preparations were made by water extraction, grinding and other traditional techniques. The preparation processes of the remaining 5 preparations were involved with alcohol extraction or alcohol precipitation. Acute toxicity test data were obtained with experimental data in mice. Clinical usages of preparation were much lower than MTD or LD50. It was concluded that these hospital TCM preparations developed by clinical experiences were with high safety.

The bile acid-responsive G-protein-coupled receptor TGR5 is expressed in monocytes and macrophages, and plays a critical role in regulating inflammatory response. Our previous work has shown its role in promoting the progression of non-small cell lung cancer (NSCLC), yet the mechanism remains unclear. Here, using Tgr5-knockout mice, we show that TGR5 is required for M2 polarization of tumor-associated macrophages (TAMs) and suppresses antitumor immunity in NSCLC via involving TAMs-mediated CD8⁺ T cell suppression. Mechanistically, we demonstrate that TGR5 promotes TAMs into protumorigenic M2-like phenotypes via activating cAMP-STAT3/STAT6 signaling. Induction of cAMP production restores M2-like phenotypes in TGR5-deficient macrophages. In NSCLC tissues from human patients, the expression of TGR5 is associated with the infiltration of TAMs. The co-expression of TGR5 and high TAMs infiltration are associated with the prognosis and overall survival of NSCLC patients. Together, this study provides molecular mechanisms for the protumor function of TGR5 in NSCLC, highlighting its potential as a target for TAMs-centric immunotherapy in NSCLC.
