Cryptogenic multifocal ulcerous stenosing enteritis（CMUSE） is a rare and difficult disease characte-rized by chronic recurrent intestinal obstruction and gastrointestinal bleeding caused by multiple ulcers and strictures of the small intestine. There is still a lack of mature and systematic guidance for the treatment of the disease. This paper reported a case of CMUSE mainly manifested as fatigue， abdominal distention， and edema of both lower limbs ， who is treated by integrated traditional Chinese and western medicine. In western medicine treatment， hormone and symptomatic treatment are mainly used. In traditional Chinese medicine treatment， the method of fortifying spleen and reinforcing healthy qi is taken as the basis； during the active stage of the disease， the method of moving qi and removing stagnation， clearing and removing dampness and heat， astringing and engendering flesh should be combined with， while during the remission stage， it is advised to unite with the method of diffusing lung and moving water， regulating and harmonizing zang-fu （脏腑） organs； simultaneously， replenishing qi and invigorating blood can be used throughout the treatment， and attach importance to the maintenance therapy of the traditional Chinese medicine immunomo-dulatory agent Tripterygium glycosides. After more than 2 years of treatment， the patient's clinical symptoms were significantly relieved， and all indicators basically restored to normal， having a stable condition.

Objective:To explore the effect of scientific research group-based model on the improvement of nursing scientific research ability in a county-level hospital.Methods:A nursing research group was established, the composition of team members and work contents of the group were clarified, tiered focused scientific research training was implemented through progressive research content and flexible training methods, and individual and progressive research guidance was provided through research counseling application forms, while literature reading activities were conducted through article reports and literature debriefings. Retrospective analysis of the nursing research practice, the number of scientific research outputs, and research capacity were applied to evaluate the effect of the nursing research group-based model.Results:Within 2 years of the establishment of the nursing research group, 37 training programs were conducted, 33 scientific research materials were pushed to the WeChat public account, 23 scientific research projects were tutored, and 6 research projects were successfully declared. The scientific research ability score of nursing staff participating in literature reading debriefing increased from 44.24±19.12 to 53.57±13.86( P<0.001). Conclusions:The application of the nursing research group-based model can improve the nursing scientific research ability of the county-level hospital.

Objective:To evaluate the potential effects of serum lipid levels, appendicular skeletal muscle mass index (ASMI) and body mass index (BMI), together with its dynamic changes, on tumor progression in renal clear cell carcinoma patients, so as to inform body weight management.Methods:This prospective cohort study included a total of 100 patients with high-risk clear cell renal cell carcinoma. Serum lipid levels were detected, ASMI and BMI were measured using bioelectrical impedance analysis and the dynamic changes of BMI were tracked. The effects of BMI, ASMI and serum lipid levels on tumor progression within 2 years were explored.Results:Patients with normal BMI and low ASMI had 5.248 (95% CI: 1.946 to 14.153, P = 0.001) times higher risk of tumor progression than those who were overweight or obese. For every 0.1-unit increase in pre-operative HDL-C, the risk of tumor progression decreased by 0.771 (95% CI: 0.631 to 0.942, P = 0.011) times. Patients who experienced more than 5% decrease in BMI compared with baseline had 5.165 (95% CI: 1.735 to 15.370, P = 0.003) times the progression risk of patients whose BMI changed within ±5% from baseline. Conclusions:The advantage of obese clear cell carcinoma patients over normal-weight patients in tumor progression-free survival may be influenced by ASMI, pre-onset involuntary weight loss and lipid levels. Therefore, patient weight management should not merely focus on absolute BMI but tailor to individual characteristics, including cancer stage, body composition and metabolic status.

Objective:To investigate the risk factors for anastomotic leakage after laparo-scopic lower anterior resection (LAR) of rectal cancer, and the application value of its risk assess-ment scoring model.Methods:The retrospective case-control study was conducted. The clinico-pathological data of 539 patients who underwent laparoscopic LAR of rectal cancer in 13 medical centers, including 248 cases in Renji Hospital of Shanghai Jiaotong University School of Medicine, 35 cases in Ningbo First Hospital, 35 cases in Changzhou Second People's Hospital, 32 cases in the First People's Hospital of Nantong, 32 cases in Linyi People's Hospital, 31 cases in Changzhou Wujin People's Hospital, 28 cases in Jiading District Hospital of Traditional Chinese Medicine, 27 cases in the First Hospital of Taizhou, 26 cases in Shanghai Pudong Gongli Hospital, 21 cases in the People's Hospital of Rugao, 11 cases in Central Hospital of Fengxian District, 7 cases in Ningbo Hangzhou Bay Hospital and 6 cases in Jiangsu jianhu People's Hospital, from January 2016 to November 2020 were collected. There were 157 males and 382 females, aged (62.7±0.5)years. Observation indicators: (1) follow-up; (2) risk factors for anastomotic leakage after laparoscopic LAR; (3) establishment of risk assessment scoring model for anastomotic leakage after laparoscopic LAR. Follow-up was conducted by outpatient examination or telephone interview. Patients were followed up at 1 week after discharge or 1 month after the operation to detect the anastomotic leakage. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were represented as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate analysis was conducted using the chi-square test and multivariate analysis was conducted usong the Logistic regression model. The area under curve of receiver operating characteristic curve was used to estimate the efficiency of detecton methods. The maximum value of the Youden index was defined as the best cut-off value. Results:(1) Follow-up: 539 patients were followed up at postoperative 1 week and 1 month. During the follow-up, 79 patient had anastomotic leakage, with an incidence of 14.66%(79/539). Of the 79 patients, 39 cases were cured after conservative treatment, 40 cases were cured after reoperation (ileostomy or colostomy). (2) Risk factors for anastomotic leakage after laparoscopic LAR. Results of univariate analysis showed that sex, age, body mass index, smoking and/or drinking, tumor diameter, diabetes mellitus, hemoglobin, albumin, grade of American Society of Anesthesio-logists (ASA), neoadjuvant chemoradiotherapy, distance from anastomotic level to dentate line, the number of pelvic stapler, reinforced anastomosis, volume of intraoperative blood loss, placement of decompression tube, preservation of left colic artery, operation time and professional doctors were related factors for anastomotic leakage after laparoscopic LAR ( χ2=14.060, 4.387, 5.039, 4.094, 17.488, 33.485, 25.066, 28.959, 34.973, 34.207, 22.076, 13.208, 16.440, 17.708, 17.260, 4.573, 5.919, 5.389, P<0.05). Results of multivariate analysis showed that male, tumor diameter ≥3.5 cm, diabetes mellitus, hemoglobin <90 g/L, albumin <30 g/L, grade of ASA ≥Ⅲ, neoadjuvant chemoradiotherapy, distance from anastomotic level to dentate line <1 cm, the number of pelvic stapler ≥3, non-reinforced anastomosis, volume of intraoperative blood loss ≥100 mL and no placement of decom-pression tube were independent risk factors for anastomotic leakage after laparoscopic LAR ( odds ratio=2.864,3.043,12.556,7.178,8.425,12.895,8.987,4.002,3.084,4.393,3.266,3.224,95% confidence interval as 1.279?6.411, 1.404?6.594, 4.469?35.274, 2.648?19.459, 2.471?28.733, 4.027?41.289, 3.702?21.777, 1.746?9.171, 1.365?6.966, 1.914?10.083, 1.434?7.441, 1.321?7.867, P<0.05). (3) Establishment of risk assessment scoring model for anastomotic leakage after laparoscopic LAR. based on the results of univariate analysis, clinicopathological factors with χ2>20, χ2>10 and ≤20 or χ2≤10 were defined as scoring of 3, 2, 1, respectively. The cumulative clinicopatho-logical factors scoring ≥6 was defined as an effective evaluating indicator for postoperative anastomotic leakage. The risk assessment scoring model (6-321) for anastomotic leakage after laparoscopic LAR was established. The cumulative value ≥6 indicated high incidence of anastomotic leakage, and the cumulative value <6 indicated low incidence of anastomotic leakage. Conclusions:Male, tumor diameter ≥3.5 cm, diabetes mellitus, hemoglobin <90 g/L, albumin <30 g/L, grade of ASA ≥Ⅲ, neo-adjuvant chemoradiotherapy, distance from anastomotic level to dentate line <1 cm, the number of pelvic stapler ≥3, non-reinforced anastomosis, volume of intraoperative blood loss ≥100 mL and no placement of decompression tube are independent risk factors for anastomotic leakage after laparoscopic LAR. The risk assessment scoring model (6-321) is established according to the above results.The cumulative value ≥6 indicates high incidence of anastomotic leakage and the cumulative value <6 indicates low incidence of anastomotic leakage.

Objective: To analyze the association between polycyclic aromatic hydrocarbons(PAHs)exposure and rheumatoid arthritis(RA)based on large sample data. Methods: The RA patients(RA group)and non-RA patients(non-RA group)with complete data were selected from the National Health and Nutrition Survey Database in the United States(NHANES)(2005—2014). The logistic regression model was used to analyze the association between 8 monohydroxylated(OH-)PAH metabolites in the urine and RA. Results: A total of 357 RA patients and 5, 256 non-RA participants were included.After adjusting the confounding factors by logistic analysis, the level of OH-PAHs mixture at the highest quartile(Q4)was associated with increased risk of RA compared with that at the lowest quartile(Q1)(OR=1.60, 95%CI: 1.16-2.23). For a single kind of OH-PAHs, the Q4 levels of 1-hydroxynaphthalene(OR=1.59, 95%CI: 1.14-2.23), 2-hydroxynaphthalene(OR=1.66, 95%CI: 1.19-2.32), 2-hydroxyfluorene(OR=1.61, 95%CI: 1.17-2.22), 3-hydroxyfluorene(OR=1.64, 95%CI: 1.18-2.27)and 1-hydroxyphenanthrene(OR=1.38, 95%CI: 1.00-1.94)were all associated with significantly increased risk of RA compared with the Q1 level(all P<0.05). However, the Q2 level of 1-hydroxypyrene(OR=0.60, 95%CI: 0.43-0.83)was related to a decreased incidence of RA(P<0.01). Conclusions OH-PAHs mixed exposure is a risk factor for RA.The association between the level of individual OH-PAH and the rate of RA is bidirectional and is depended on the type and concentration of OH-PAHs.

OBJECTIVE: To evaluate the efficacy and safety of hydroxychloroquine (HCQ) in the treatment of patients with moderate coronavirus disease 2019 (COVID-19). METHODS: We prospectively enrolled 30 treatment-naïve patients with confirmed COVID-19 after informed consent at Shanghai Public Health Clinical Center. The patients were randomized 1：1 to HCQ group and the control group. Patients in HCQ group were given HCQ 400 mg per day for 5 days plus conventional treatments, while those in the control group were given conventional treatment only. The primary endpoint was negative conversion rate of SARS-CoV-2 nucleic acid in respiratory pharyngeal swab on days 7 after randomization. This study has been approved by the Ethics Committee of Shanghai Public Health Clinical Center and registered online (NCT04261517). RESULTS: One patient in HCQ group developed to severe during the treatment. On day 7, nucleic acid of throat swabs was negative in 13 (86.7%) cases in the HCQ group and 14 (93.3%) cases in the control group (>0.05). The median duration from hospitalization to virus nucleic acid negative conservation was 4 (1,9) days in HCQ group, which is comparable to that in the control group [2 (1,4) days, Z=1.27, >0.05]. The median time for body temperature normalization in HCQ group was 1 (0,2) day after hospitalization, which was also comparable to that in the control group [1 (0,3) day]. Radiological progression was shown on CT images in 5 cases (33.3%) of the HCQ group and 7 cases (46.7%) of the control group, and all patients showed improvement in follow-up examinations. Four cases (26.7%) of the HCQ group and 3 cases (20%) of the control group had transient diarrhea and abnormal liver function (>0.05). CONCLUSIONS The prognosis of COVID-19 moderate patients is good. Larger sample size study are needed to investigate the effects of HCQ in the treatment of COVID-19. Subsequent research should determine better endpoint and fully consider the feasibility of experiments such as sample size.
