OBJECTIVE:To investigate the perioperative prophylactic use of antibiotics in thoracic surgery department of 7 hos-pitals in Nantong city,and to provide reference for rational drug use in clinic. METHODS:In retrospective study,6652 dis-charged patients with thoracic surgery were selected from 7"third-level hospitals"of Nantong city during 2015-2016. The gender, age,length of stay,preoperative medication,medication timing,classification of incision,operation time,drug name,usage and dosage,route of administration,drug combination and prognosis were analyzed statistically. According to the relevant regulations of special rectification and the principle of perioperative antibiotics use,the rationality of antibiotics use was evaluated. RE-SULTS:Among 6652 patients,there were 2761 cases of typeⅠincision and 3891 cases of typeⅡincision. All of them used anti-biotics. Primary prophylactic time was 0.5-2 h before operation in 5282 cases,accounting for 79.40％;1370 cases were given medicine more than 2 h before surgery or after surgery,accounting for 20.60％. Totally 1070 cases received prophylactic medica-tion within 48 h,accounting for 16.09％;5582 cases received prophylactic medication more than 48 h,accounting for 83.91％. A total of 5702 cases were given only one antibiotic,and 950 cases received two-drug combination. A total of 6342 patients used an-tibiotics irrationally,accounting for 95.34％. Eight categories 15 kinds of antibiotics were involved. β-lactam/β-lactamase inhibi-tors,fluoroquinolones and cephalosporins were mostly used. CONCLUSIONS:After the implementation of special rectification, there are still many irrational phenomena in the prophylactic use of antibiotics in thoracic surgery department of 7 hospitals in Nan-tong city. Some indexes exceed the national standard and still need to be further managed and improved.

Objective:To investigate the potential key targets of Liujun Anwei Prescription and its effects on NF-κB/iNOS-NO in small intestine of mice with chemotherapy- associated diarrhea; To reveal the anti-inflammatory components and molecular mechanism.Methods:UPLC-Q/TOF MS combined with UNIFI software was used to analyze the chemical components of Liujun Anwei Prescription. PubChem database was searched to obtain the active components of Liujun Anwei Prescription, and the Swiss Target Prediction was used to predict the targets. The database of DisGeNET, OMIM and GeneCards were searched to obtain the targets of chemotherapy-related diarrhea. The potential targets of Liujun Anwei Prescription in the treatment of chemotherapy-related diarrhea diseases were obtained by crossing the targets of active components of Liujun Anwei Prescription and those related to diarrhea diseases. The PPI network and component-target-pathway network were constructed by Cytoscape 3.7.1 software, and the intersecting targets were analyzed by GO and KEGG based on David Database. The potential active components and potential targets predicted in the network were verified by using Autodock software. 60 C57BL/6J male mice were divided into normal control group, model group, positive control group and Liujun Anwei Prescription high-, medium- and low-dosage groups according to random number table method, with 10 mice in each group. In addition to the normal control group, the other groups of mice were intraperitoneally injected with 5-fluorouracil injection 50 mg/kg preparation to construct CID mouse model. After 14 days, the expressions of NF-κB and iNOS in jejunum were detected by Western blot.Results:A total of 197 compounds were identified, and 156 key compounds of Liujun Anwei Prescription were screened, involving 82 potential targets, mainly through NOS2 and other key targets, playing a role through cancer pathway, PI3K-Akt, NF-κB signal pathway. The experimental results showed that Liujun Anwei Prescription could significantly down-regulate the protein expressions of NF-κB and iNOS.Conclusion:This study reveals the pharmacodynamic material basis of Liujun Anwei Prescription, which can be achieved by decreaseing the levels of NF-κB and iNOS to affect the inflammatory response of intestinal tissue, improve intestinal mucosal barrier function, and thus improve chemotherapy related diarrhea.

Objective:To explore the relationship between the new Tumor-Node-Metastasis (TNM) staging system and the serum CA125 level with the prognosis of malignant peritoneal mesothelioma (MPeM) .Methods:The clinical data of 74 patients with MPeM diagnosed by pathology and immunohistochemistry were collected from January 2005 to June 2016 in Cangzhou Central Hospital. According to the results of CT-peritoneal carcinoma index (PCI) , the tumor load was divided into T1 (PCI 1-10) , T2 (PCI 11-20) , T3 (PCI 21-30) and T4 (PCI 31-39) , combined with lymph node metastasis and extraperitoneal metastasis, a new TNM staging system was established. And serum CA125 level was measured in the same time. The median survival time of patients with MPeM, the effect of the new TNM staging system, and serum CA125 levels on their prognosis were retrospectively analyzed.Results:Among the 74 patients with MPeM, 25 (33.8%) cases were males and 49 (66.2%) cases were females. There were 8 cases with systemic chemotherapy, 8 cases with heated intraperitoneal chemotherapy, and 1 case with combination chemotherapy. 10 cases were T1, 22 cases were T2, 27 cases were T3, 15 cases were T4, 12 cases had lymph node metastasis and 10 cases had distant metastasis. The median survival time of T1, T2, T3 and T4 were 12, 10, 6 and 3 months respectively. There were 38 (77.6%) cases with high serum CA125 in all 49 cases who have been tested for CA125. The median survival time of positive group and negative group were 6 months and 11 months respectively. 68 (91.9%) patients had died by the end of collecting data. The median survival time was 8 months. Univariate analysis showed that there were significant differences in survival time between patients with different CT-PCI stages, serum CA125 levels, and with or without lymph node and extraperitoneal metastasis ( P<0.05) . Multivariate analysis showed that CT-PCI was independent risk factors for the prognosis of MPeM ( HR=2.203, 95% CI: 1.475-3.289) . Conclusion:The new TNM staging system and serum CA125 are important for the prognosis of patients with MPeM. Early detection, early diagnosis and comprehensive treatment can improve the survival time of patients with MPeM.

Objective:To understand the prevalence and epidemiological characteristics of glaucoma among people over 40 years old in rural areas of Chongqing.Methods:From August to October 2018, a stratified cluster random sampling method was used to investigate the cases of glaucoma among people over 40 years old in a rural population of the Rongchang and Qijiang Districts in Chongqing.The subjects had been living in the local area for over ten years.Basic information for each patient, including gender and age was documented, and their visual acuity and intraocular pressure were routinely measured.The Van Herick method was used to evaluate the depth of the central and peripheral anterior chamber, a preset lens was used to examine the fundus, and the cup to disc ratio(C/D) of the optic disc was emphasized.All suspected glaucoma patients underwent further standard glaucoma examinations.This study protocol was approved by the Ethics Committee of the First Affiliated Hospital of Army Medical University.Results:A total of 4 680 people were identified, and 4 073 respondents participated in the survey, and the response rate was 87%.The prevalence of glaucoma was 1.72% (70/4 073). There were no significant differences in the prevalence of primary angle-closure glaucoma (PACG) and primary open angle glaucoma (POAG) between different genders ( χ2=0.042, P=0.837; χ2=2.838, P=0.092). The prevalence of glaucoma in people over 70 years old was 2.5%, significantly higher than that in other age groups.In patients with glaucoma, the rate of visual impairment was 68.57%(48/70), and the rate of blindness was 47.14%(33/70). There was no significant difference in the incidence of low vision between different types of glaucoma ( χ2=2.785, P=0.248), but there was a significant difference in the rate of blindness ( χ2=10.668, P=0.005). The highest rate of blindness was found in secondary glaucoma.The detection rate of intraocular pressure, anterior chamber depth and C/D was statistically significant ( χ2=43.325, P<0.001), and the positive rate of C/D was the highest.When the factors of intraocular pressure, and C/D were considered jointly, the detection rate of glaucoma could be increased to 55.88%. Conclusions:The prevalence of glaucoma is 1.72% among people over 40 years old in rural areas of Chongqing, the prevalence of PACG is lower than previously recorded, but the proportion of glaucoma-induced visual impairment is higher.In field screening, the morphological examination of the fundus optic nerve is very important for the diagnosis of glaucoma.
