Objective To explore the clinical characteristics, risk factors of mortality and antimicrobial therapy of carbapenemresistant Klebsiella pneumoniae (CRKP) bloodstream infections. Methods A 5-year retrospective study was conducted for 60 patients with CRKP bloodstream infection, who were treated in Chinese People's Liberation Army (PLA) General Hospital during the period from June 2011 to August 2016. The patients were assigned to death (n=24) or survival (n=36) group according to 28-day survival after bloodstream infection to identify the predictors of mortality. The patients treated with combination antimicrobial therapy (n=32) were compared with those received monotherapy (n=14). Results A total of 60 nonduplicate CRKP blood isolates were identified. The 28-day mortality was 40.0% (24/60). High APACHE Ⅱ score (OR=1.15, 95% CI 1.0-1.3, P=0.048) was identified as an independent risk factor for 28-day mortality in patients with CRKP bloodstream infection. The 46 patients receiving antimicrobial therapy showed 28-day mortality of 34.8%. Univariate analysis indicated that the 28-day mortality rate was similar between the patients receiving combination antimicrobial therapy and those receiving monotherapy. Conclusions Bloodstream infection due to CRKP is associated with high mortality. APACHE II score is an independent predictor for mortality in patients with CRKP bloodstream infection.

OBJECTIVETo systematically evaluate the efficacy and safety of surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of advanced gastric cancer (AGC).
METHODSClinical control trials about the efficacy and safety of surgery combined with HIPEC in the treatment of advanced gastric cancer published before June 2014 were searched in Embase, PubMed, Cochrane Library, Wanfang database and CNKI database. Quality of enrolled articles was evaluated with the guidelines from Cochrane collaborative network. All the retrieved data were analyzed by RevMan 5.3 software for meta-analysis. Sensitivity analysis was performed by exclusion of non-randomly clinical control trials. Publication bias was evaluated by failure safe number (Nfs0.05).
RESULTSOf the 1489 AGC cases included from 16 literature, 698 underwent surgery with HIPEC (HIPEC group) while 791 underwent surgery alone (control group). According to whether or not the patient presented macroscopic peritoneal metastasis before the surgery, the HIPEC group was further divided into the curative HIPEC (n=102) and prophylactic HIPEC groups (n=421). The results of meta-analysis showed that, compared with control group, the 1-year (OR=2.26, 95%CI:1.71 ~ 3.00, P=0.000), 3-year (OR=2.27, 95%CI:1.80 - 2.87, P=0.000) and 5-year (OR=1.58, 95%CI:1.20 - 2.07, P=0.001) survival rates of HIPEC group were significantly improved with significantly decreased overall recurrence rate of liver, lung, bone or peritoneal metastasis (OR=0.43, 95%CI:0.26 - 0.71, P=0.001) and lower peritoneal metastasis recurrence rate (OR=0.30, 95%CI:0.17 - 0.52, P=0.000). However, there was higher incidence of procedure-related morbidity in the HIPEC group (OR=1.67, 95%CI:1.13 - 2.45, P=0.009), whereby the incidences of myelotoxicity (OR=4.90, 95%CI:1.05 - 22.83, P=0.040) and renal insufficiency were higher (OR=3.59, 95%CI:1.67 - 7.74, P=0.001). While the other complications, such as anastomotic leakage, intestinal obstruction and respiratory diseases were not significantly different between the two groups(all P>0.05). Subgroup analysis showed that compared with control group, the rates of peritoneal recurrence and metastasis in the prophylactic HIPEC group were significantly lower (OR=0.34, 95%CI:0.24 - 0.48, P=0.000), while such rates were not significantly different in curative HIPEC group (OR=0.07, 95%CI:0.00 - 1.88, P=0.110).
CONCLUSIONSSurgery combined with HIPEC can improve survival of AGC patients and reduce the recurrence rate after surgery. However its safety should be improved in the future.

Objective Taking Chinese college students as the target group,this study detected the distribution of plantar pressure in different gait groups and analyzed the distribution characteristics of plantar pressure in in-toeing gait populations,to provide references for their orthopedic rehabilitation.Methods Ten subjects with typical in-toeing and normal and out-toeing gaits were selected to participate in the plantar pressure testing experiment.The maximum force,pressure,and contact time during natural standing and during one walking gait cycle were measured using a Zebris foot plantar pressure measurement system.Gait parameters,including step length,step width,step speed,step direction angle,gait center line,and force change curves,were collected,and a hazard analysis was conducted.Results During natural standing,the swaying interval area of the center of pressure was 939.0±252.4 mm2 for the in-toeing gait group and 1 120.2±101.6 mm2 for the out-toeing gait group,which was larger than that for the normal group(240.7±130.6 mm2).The in-toeing gait further weakens the human body's ability to maintain stability.The dynamic and static plantar pressures in the three gait groups exhibited different distribution characteristics.During static standing,the pressure center of the in-toeing gait group shifted to the hindfoot,which accounted for 70%of the plantar pressure and was higher than that of the normal group.During dynamic walking,the absolute value of peak pressure in the tripodal area of the foot in the in-toeing gait group was higher than that in the other two groups.Conclusions The in-toeing gait group had poor static maintenance ability,and to a certain extent,the distribution of plantar pressure in the foot tripodal area and plantar zone pressure were different compared with that of the normal gait.This led to poor stability,easy muscle fatigue,and ankle and knee joint injuries in the in-toeing gait group under equal-intensity exercise conditions.

OBJECTIVE To explore the action mechanism of kushenol F (KSCF) in treating ulcerative colitis (UC) in mice. METHODS The potential targets of KSCF intervening in UC were predicted with network pharmacology and molecular docking. C57BL/6J mice were randomly divided by body weight into model group, positive control group (sulfasalazine, 703 mg/kg), KSCF group (100 mg/kg), and normal group, with 6 mice per group. The UC model of mice was induced by dextran sulfate sodium solution. During the modeling period, the mice were given relevant medicine intragastrically, once a day, for 7 consecutive days. After the last administration, the disease activity index (DAI) of the mice was scored; the length of the mice’s colon was measured; pathological changes in the colon tissue of mice were observed; the levels of lipopolysaccharide (LPS) in serum, myeloperoxidase (MPO), nitric oxide (NO) and superoxide dismutase (SOD) in the colon were detected in mice; the expression levels of occludin and ZO-1 in colon tissue of mice were detected; the proportions of CD3+T, CD4+T, and CD8+T lymphocytes in the spleen and the ratio of CD4+/CD8+ were detected; changes in colonic microbiota were analyzed by 16S rDNA sequencing. RESULTS Results of network pharmacology indicated that KSCF may treat UC by regulating signaling pathways such as phosphatidylinositol-3 kinase/protein kinase B (PI3K/AKT) and nuclear factor kappa B (NF- κB). Molecular docking results showed that KSCF bound most stably with NF-κB p65 protein. Animal experiment results demonstrated that, compared with the model group, the pathological characteristics of colon tissue in mice were improved in KSCF group. DAI scores, serum levels of LPS, the levels of MPO,NF-κB p65 phosphorylation and NLRP3 protein expression in the colon, and the proportion of CD8+T lymphocytes in the spleen were reduced significantly (P<0.05). Body weight, SOD levels, expression levels of occludin and ZO-1 in the colon, proportions of CD3+T and CD4+T lymphocytes, and the CD4+/CD8+ ratio in the spleen were significantly increased (P<0.05); the abundance of Firmicutes, Actinobacteria, Akkermansia, and Lactobacillus genera were increased, while Proteobacteria decreased; the microbial community structure tended towards that of the normal group. CONCLUSIONS KSCF alleviates UC by restoring intestinal microbial imbalance, enhancing immune response, and inhibiting colonic inflammatory responses, thereby improving intestinal barrier integrity.

BACKGROUND:
Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE).
METHODS:
This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE.
RESULTS:
This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively.
CONCLUSIONS
Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.
