Objective To explore the role and intrinsic mechanism of the injury of intestines induceded by pancreatitis associated ascitic fluid (PAAF) and acute suppurative peritonitis associated ascitic fluid (ASPAAF) in rats. Methods Forty-eight Sprague-Dawley (SD) rats, male or female, were randomly divided into three groups averagely. The control group: 8 ml of normal saline (NS) was injected into the peritoneal cavity; the PAAF group: 8 ml of PAAF was injected into the peritoneal cavity; and the ASPAAF group: 8 ml of ASPAAF was injected into the peritoneal cavity. After peritoneal cavity injection, the rats were put to death in batches at 6 h and 12 h, eight rats per-batch. Levels of TNF-α and endotoxin in serum were measured. The activity of ATP enzyme and level of TNF-α in the intestinal tissues were measured. The pathological changes of intestines were observed by microscope.Results The levels of TNF-α, endotoxin and the degree of injury of the intestines were markedly elevated and the activity of ATP enzyme of the intestinal tissues was decreased in the PAAF group and ASPAAF group compared with those in the control group (P＜0.05). The levels of TNF-α, endotoxin and the degree of injury of the intestines were markedly elevated and the activity of ATP enzyme of the intestinal tissues was decreased in the ASPAAF group compared with those in the PAAF group (P＜0.05). Conclusion PAAF and ASPAAF can induce the injury of intestines, but the injury of intestines induced by ASPAAF is more serious.
Objective To investigate predictive value of procalcitonin (PCT) and C-reactive protein (CRP) levels for spontaneous bacterial peritonitis (SBP) in patients with liver cirrhosis ascites. Methods The clinical data of 140 patients with liver cirrhosis ascites treated in our hospital from January 2012 to January 2016 were retrospectively analyzed. According to the presence of SBP, these patients were divided into SBP group and non-SBP group. The clinical data were compared between these two groups. The receiver operating characteristic (ROC) curve was constructed to assess their sensitivities and specificities of PCT and CRP for diagnosis of SBP. Results The PCT and CRP levels of the SBP group were significantly higher than those of the non-SBP group (P<0.05). The differences of serum ALT, AST and white cell count between the SBP group and the non-SBP were not statistically significant (P>0.05). The ROC curve analysis showed that the area under the ROC curve of PCT and CRP were 0.895 and 0.926, their corresponding cut-off value 2.1 μg/L and 24.8 mg/L, the sensitivities were 86.9% and 89.5%, the specificities were 85.1% and 83.5%, respectively. Conclusion Abnormally elevated PCT and CRP levels might have an important detective value for SBP in patients with liver cirrhosis ascites.
Objective To investigate the pathogenesis of acute lung injury in rats induced by intra-peritoneally injection of perforative peritonitis ascitic fluids（PPAF） and the role of L-arginine （L-Arg） in acute lung injury in this model. Methods Perforative peritonitis （PP） models were established in 60 rats and PPAF were collected. Forty-eight rats were randomly divided equally into NS group，PPAF group, and L-Arg group. Rats were randomly subjected to death at 7 h and 12 h. Peripheral blood WBC were counted，levels of NO and malondialdehyde （MDA） in serum were examined. Lung injury score and wet/dry ratio were evaluated， and level of myeloperoxidase （MPO） in lung tissues and lung cell apoptosis were tested. Results WBC count of peripheral blood, levels of NO and MDA in serum， level of MPO in lung tissue, lung injury score， wet/dry ratio， and lung cell apoptosis rate in PPAF group were significantly higher than that in NS group at each time point（P＜0.01）. Level of NO in serum in L-Arg group was higher than that in PPAF group （P＜0.01）， but lower level of MDA in serum， lower level of MPO in lung tissue and lung injury score，lower wet/dry ratio， and lung cell apoptosis rate were observed in L-Arg group（P＜0.05）. In PPAF group and L-Arg group， level of NO in serum， wet/dry ratio, and lung cell apoptosis rate were higher at 12 h than that at 7 h（P=0.000）. Serum NO level was in negative correlation with serum MDA level （r=-0.257，P=0.021）， MPO level in lung tissue（r=-0.444， P=0.011），and lung cell apoptosis（r=-0.351， P =0.010） in PPAF group and L-Arg group， but serum MDA level was in positive correlation with cell apoptosis（r=0.969， P＜0.001） in each group. Conclusions Acute lung injury rats model can be established by intra-peritoneally injection of PPAF. Enhanced oxidizing reaction and cell apoptosis take part in the occurrence of acute lung injury. L-Arg plays a protective role in acute lung injury.
目的 探讨肝硬化腹水患者不同血清钠水平与病情严重程度的关系。 方法 回顾分析2008年7月－2010年6月收治47例肝硬化腹水并发低钠血症患者，根据其入院时血清钠水平分为低钠血症轻（A组）、中（B组）、重（C组）3组。比较肝硬化腹水患者不同血钠水平的腹水程度及疗效的关系、以及低钠程度与肝性脑病、肝肾综合征和死亡发生率的关系。 结果 与A组比较，B、C两组腹水量、肝性脑病、肝肾综合征及病死率明显增高，差异有统计学意义（P＜0.05）；对治疗的效果明显降低（P＜0.05）。 结论 肝硬化腹水患者的血清钠水平与其病情程度具有紧密相关性，监测血清钠的水平可作为判断病情严重程度的重要指标之一，提示在临床上需重视预防、及时发现并治疗低钠血症。
【摘要】 目的 应用受试者工作特征曲线（receiver operating characteristic curve，ROC曲线）探讨α-L-岩藻糖苷酶（AFU）对恶性腹水和非结核良性腹水的诊断价值。 方法 2004年7月—2008年1月对213例诊断明确的良、恶性腹水（其中良性腹水117例、恶性腹水96例）AFU活性进行检测。采用ROC曲线评价AFU的诊断灵敏度、特异度、准确性、阳性预测值、阴性预测值、阳性似然比、阴性似然比及Youden指数，评价其诊断效率。 结果 恶性腹水组AFU水平（164.96±87.72） μmol/（L•h），良性腹水组（104.02±62.07） μmol/（L•h），两者比较差异有统计学意义（Plt;0.01）。AFU诊断恶性腹水的ROC 曲线下面积为0.754±0.034，最佳分界值101.95 μmol/（L•h）。以AFU≥101.95 μmol/（L•h）来预测恶性腹水，其诊断的灵敏度为82.3%，特异度为63.2%，准确性为72.8%、阳性预测值为65.3%、阴性预测值为83.1%、阳性似然比为2.23、阴性似然比为0.28及Youden指数为0.455。 结论 腹水AFU活性检测有助于恶性腹水和非结核良性腹水的鉴别诊断，是一个比较理想的实用指标，适合于基层医院的临床应用。【Abstract】 Objective To assess the value of α-L-fucosidase (AFU) levels with receiver operating characteristic curve (ROC curve) in the diagnosis of malignant and non-tuberculous benign ascites. Methods Ascitic AFU activity was measured in 213 patients (117 with benign ascites and 96 with malignant ascites) diagnosed with benign or malignant ascites. The diagnostic sensitivity (SEN), specificity (SPE), accuracy, positive predictive value (PV+), negative predictive value (PV-), positive likelihood ratio (LR+), negative likelihood ratio (LR-) and Youden index (YI) of AFU were assessed with receiver operating characteristic curve, and the diagnostic effectiveness of AFU was evaluated. Results The average level of AFU in the malignant group [(164.96±87.72) μmol/(L•h)] was significantly higher than that in the benign group [(104.02±62.07) μmol/(L•h)] (Plt;0.01). The area under the curve (AUC) of the ROC curve of AFU was 0.754±0.034 for malignant ascites diagnosis, and the optimal cut-off value was 101.95 μmol/(L•h). When an AFU level equal to or higher than 101.95 μmol/(L•h) was used to predict malignant ascites, the diagnostic sensitivity was 82.3%, specificity was 63.2%, accuracy was 72.8%, PV+ was 65.3%, PV- was 83.1%, LR+ was 2.23, LR- was 0.28 and YI was 0.455. Conclusion Detection of AFU activity in ascites is helpful to differentiate the diagnose between malignant and non-tuberculous benign ascites, which is a relatively ideal index to fit for clinical application of local hospitals.

Objective To systematically review the effectiveness and safety of hyperthermia (HT) plus intraperitoneal hyperthermic perfusion chemotherapy (IHPC) versus IHPC alone for malignant ascites. Methods Such databases as PubMed, The Cochrane Library, EMbase, VIP, WanFang, CNKI and CBM were electronically and comprehensively searched for randomized controlled trials (RCTs) on HT plus IHPC vs. IHPC alone for malignant ascites from inception to March 2013. Two reviewers independently screened studies according to inclusion and exclusion criteria, extracted data and assessed quality of the included studies. References of the included studies were also retrieved. Then, meta-analysis was performed using RevMan 5.1 software. Results A total of 16 RCTs involving 984 patients were included. The results of meta-analysis showed that, compared with the IHPC alone group, the HT plus IHPC group had a higher effective rate of controlling ascites (OR=3.40, 95%CI 2.58 to 4.48, Plt;0.000 01), better improvement in quality of life (OR=2.77, 95%CI 1.90 to 4.05, Plt;0.000 01), with significant differences. The two groups were alike in 1-year survival with no significant difference (OR=1.80, 95%CI 0.61 to 5.31, P=0.28). As for safety, there was no significant difference between the two groups in the incidences of nausea and vomiting, abdominal distension and pain, myelosuppression, diarrhea, and constipation. Conclusion The results of this systematic review show that, compared with IHPC alone, HT plus IHPC improves the effective rate as well as the quality of life of patients with malignant ascites, and it does not increase the incidences of adverse reactions. Due to the limited quality and quantity of the included studies, more high quality RCTs with larger sample size are needed to verify the above conclusion.
