Objective To assess the risk factors for pneumonia in patients with acute stroke. Methods Three hundred and forty patients with acute stroke were studied, and risk factors for pneumonia such as demographics, history of hypertension, diabetes and smoking, initial blood pressure, body temperature, fasting plasma glucose level, C-reactive protein, National Institutes of Health Stroke Scale ( NIHSS) scores, degree of dysphagia and mechanical ventilation were evaluated. Besides, the correlation between incidence of pneumonia and pneumonia scores in patients with acute stroke was studied. Results Pneumonia was developed in 63 patients (18.5%). Logistic regression analysis revealed that age, gender, initial NIHSS scores, dysphagia and mechanical ventilation were independent predictors for pneumonia (P <0.05). The incidence of pneumonia gradually increased with the pneumonia scores. Conclusion The occurrence of pneumonia after acute stroke is associated with older age, male gender, high NIHSS scores, dysphagia and mechanical ventilation. The pneumonia scores can be adopted to identify the risks of pneumonia after acute stroke.

OBJECTIVETo investigate the expression of IFITM3 in colorectal carcinoma and its clinical significance.

METHODS213 patients with colon ademocarcinoma and 214 patients with colon adenoma treated by surgery in our hospital from March 2008 to June 2010 were included in this study. The levels of IFITM3 in normal colon nucosa, adenoma, and adenocarcinoma tissues were detected by real-time PCR and immunochemistry, and its relationship with metastasis and prognosis in 213 colorectal cancer patients was analyzed.

RESULTSThe IFITM3 mRNA level in metastatic tumor group was 18.37 ± 0.61, significantly higher than that in the normal 4.49 ± 0.69 and non-metastases groups (7.32 ± 0.76; F = 460.380, P < 0.001). The positive rate of IFITM3 protein expression in metastatic tumor group (69.0%) was significantly higher than that in the normal (3.9%), non-metastasies groups (19.0%) and adenoma groups (11.3%). Our clinical analysis confirmed that the IFITM3 expression was associated with peritumoral invasion, hepatic metastases, metastases of para-colonic lymph nodes, mesocolonic lymph nodes and mesenteric root lymph nodes, omental metastasis and AJCC classification (P < 0.05). Furthermore, the survival curve analysis showed that patients with lower IFITM3 level expression had a higher 5-year survival rate (88.8%) than that in the patients with higher expression (40.2%, P < 0.001).

CONCLUSIONSIFITM3 expression has a positive correlation with metastasis and prognosis in patients with colorectal carcinoma.

OBJECTIVE: To explore the influence of long non-coding (lnc) RNA Gm15645 on the podocyte injury in mice with diabetic nephropathy. METHODS: Male db/db mice (with Type 2 diabetes) with a genetic background of C57BLKs/J and db/m mice (healthy) born in littermates were randomly divided into three groups. db/db group was injected with lncRNAGm15645 shRNA lentivirus with a podocyte-specific marker NPHS2; db/db blank group was injected with saline, and db/db control group was injected withnon-sense lentivirus. The results of PAS staining, pathological changes of renal tissue, relative expression of GSK-3beta, and podocin expression were compared. RESULTS: lncRNAGm15 645 was overexpressed and podocin was down-regulated in the lentivirus overexpressed group. Mesangial cell proliferation, mesangial matrix hyperplasia, thickened basement membrane, widely fused foot process, and podocyte injury were observed by PAS staining. The expression of Gm15645 in the db/db group was significantly lower than that of the db/db blank group and db/db control group (P< 0.05), while the expression of podocin was higher (P< 0.05). Gm15645 was co-stained with podocin in renal tissue, and the target gene was GSK-3beta. CONCLUSION lncRNAGm15645 may provide an early biomarker for the occurrence of podocyte injury in diabetic nephropathy. The mechanism may be related to the feedback regulation of GSK-3beta gene.

Objective:To search for valuable laboratory indexes of early diagnosis of anastomotic leakage after anterior resection for rectal carcinoma.Methods:From Sep 2017 to Jan 2019, 128 patients with colorectal cancer underwent anterior rectal resection at the Department of Colorectal & Anal Surgery, the 940 Hospital of the Joint Logistics Support Force.Results:Anastomotic leakage occurred in 16 of 128 patients (12.5%). Definite diagnosis of anastomotic leakage was made on between 2nd and 9th day, postopera tively averagign (6.13±2.00) days. Tumor location was a risk factor for anastomotic leakage with the incidence significantly lower when the distance from the lower edge of the tumor to the anal margin >7 cm than when the distance ≤7 cm ( χ 2=6.022, P=0.014). The percentage of increase in peripheral blood leukocytes, neutrophils, serum interleukin-6, C-reactive protein and procalcitonin in patients 3-5 days after surgery significantly related to the occurrence of anastomotic leakage (all P<0.05). The area under the working characteristic curve of the subjects with the percentage of C-reactive protein, procalcitonin, interleukin-6, leukocytes and neutrophils from the 3rd to the 5th day after operation was greater than 0.5. Conclusion:C-reactive protein, procalcitonin, interleukin-6, leukocyte and neutrophil percentage are risk factors predicting anastomotic leakage after anterior resection of rectal cancer.
