Analysis of risk factors of cervical anastomotic leakage after esophageal cancer operation / 中国胸心血管外科临床杂志

@#Objective    To analyze the risk factors of anastomotic leakage after esophagectomy. Methods    The clinical data of 1 328 patients with esophageal cancer, who underwent esophagectomy in the First Affiliated Hospital of Henan University of Science and Technology from January 2010 to December 2016, were retrospectively analyzed. There were 726 males and 602 females, at an average age of 67.2±14.1 years. According to whether there was anastomotic leakage after operation, patients were divided into two groups: an anastomotic leakage group (167 patients) and a non-anastomotic leakage group (1 161 patients). Univariate and multivariate logistic regression analysis was used to identify related risk factors of anastomotic leakage after operation. Results     The incidence of postoperative anastomotic leakage was 12.6% (167/1 328). Univariate analysis showed that body mass index, arrhythmia, chronic obstructive pulmonary disease (COPD), diabetes, preoperative albumin level, preoperative chemotherapy and chemoradiotherapy, lesion location, anastomosis types and postoperative pulmonary infection were associated with statistically significant increase in risk of cervical anastomotic leakage (P<0.05). Logistic regression analysis showed that preoperative COPD, lesion location and postoperative pulmonary infection were independent risk factors of cervical anastomotic leakage after esophagectomy (P<0.05). Conclusion    The occurrence of cervical anastomotic leakage after esophageal cancer is related to many factors. The preoperative COPD, the lesion location and the postoperative pulmonary infection are independent high risk factors. Paying attention to these factors and doing perioperative management can effectively reduce the occurrence of anastomotic leakage.

Advantages and evidences research on Chinese medicine for treatment of pelvic inflammatory disease / 中国中药杂志

Pelvic inflammatory disease is an infectious disease. At present, Western medicine is mainly treated with antibiotics. However, the situation of antibiotics abuse is so grim that the potential risks such as the imbalance of bacteria, the resistance of bacteria, the production of super bacteria and the increase of adverse reactions are becoming more and more serious. Therefore, it is urgent to find a way to supplement or substitute antibiotics for the treatment of this disease. Traditional Chinese medicine treatment of the disease is effective and has its unique advantages. This paper mainly discusses the advantages and evidences of traditional Chinese medicine (TCM) treatment of pelvic inflammatory disease, to further prove the effectiveness and safety of TCM treatment and to provide medical evidence of reducing antibiotics use.

Protective effect of extract of Apocynum venetum on kidneys of streptozotocin-induced diabetic rats / 药学学报

The aim of this study is to investigate the effects and mechanism of extract of Apocynum venetum (AV) on kidneys of streptozotocin-induced diabetic rats. Diabetes mellitus (DM) was induced in rats by intraperitoneal injection of streptozotocin (STZ). The indexes of the blood glucose, renal function and oxidative stress were observed. The DM rats were administrated with the AV for 8 weeks, the above-mentioned indexes were detected. The blood glucose level, BUN, 24 h urine protein excretion, urine volume, renal index, renal cortex's MDA level in model groups all increased significantly. Renal cortex's SOD and GSH activities decreased significantly compared with the normal control group (P < 0.05). The above-mentioned indexes were significantly improved by the AV treatment (P < 0.05). AV have protective effects on renal function of kidneys of streptozotocin-induced diabetic rats, and maybe via inhibition of the renal oxidative stress.

The value of endoscopic mucosal resection for dysplasia and early-stage cancer of the esophagus and gastric cardia / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate the long-term effect and clinical value of endoscopic mucosal resection (EMR) with transparent cap for dysplasia and early-stage cancer of the esophagus and gastric cardia.</p><p><b>METHODS</b>From September 1996 to June 2007, 154 lesions in the esophagus or gastric cardia of 147 patients were treated using EMR with transparent cap. Among the lesions, there were 69 early-stage squamous-cell carcinomas in 64 patients and 47 squamous cell precancerous lesions of the esophagus in 45 patients, with an average lesion size of (14.8 +/- 6.1) mm (range, 3-40 mm), furthermore, there were 23 early-stage adenocarcinomas in 23 patients and 15 precancerous lesions in the gastric cardia in 15 patients, with an average lesion size of (8.2 +/- 4.3) mm (rang, 5-25 mm). All lesions were finally confirmed histopathologically.</p><p><b>RESULTS</b>Of the 154 lesions, 139 (90.3%) were resected completely through EMR procedure. A close relationship between the complete resection rate and the lesion size was observed. The bigger the lesion size, the lower the complete resection rate. Endoscopic follow-up was carried out in 7 patients for more than 10 years, in 43 for 5 - 10 years, in 31 for 3 - 5 years and in 66 for less than 3 years. Of 11 dead patients during following-up, 10 died of other diseases, only 1 of recurrence. The 5-year survival rate was 96.2% for early-stage esophageal cancer, and 100% for early cancer of the gastric cardia. Perioperative complications included oozing bleeding in 5 patients (3.4%) and stricture in 1 (0.7%), no perforation occurred in this series.</p><p><b>CONCLUSION</b>Endoscopic mucosal resection is suitable to treat precancerous lesions or early-stage esophageal cancers without invasion into submucosa. Compared with conventional resection through open thoracotomy, similar long-term survival and curative effect can be achieved by this EMR treatment, preserving a good quality of life.</p>
