Objective This meta-analysis assessed the value of interferon-γ release assays (IGRAs) in the differential diagnosis of intestinal tuberculosis (ITB) from Crohn's disease (CD).Methods Systematic search without language restriction was conducted in the main computerized databases until June 2015.Studies that have evaluated the performance of IGRAs (QuantiFERON-TB Gold or T-SPOT.TB) in distinguishing ITB from CD were eligible.Main outcome measures included sensitivity and specificity.Area under the curve (AUC) of the summary receiver operating characteristic (sROC) curve was used to evaluate the accuracy of IGRAs.Results Twelve studies (all from Asia) were finally included.The pooled sensitivity and specificity of IGRAs for the differential diagnosis of ITB from CD were 82.8% (95%CI 78.4%-86.6%) and 86.7% (95% CI 83.2%-89.6%) respectively.The positive likelihood ratio (PLR) and negative likelihood ratio (NLR) were 6.870 (95% CI 5.345-8.830) and 0.171 (95% CI 0.105-0.279).The diagnostic odds ratio was 44.030 (95% CI 27.964-69.325).And the AUC of sROC was 0.939.Conclusions IGRAs have a high sensitivity and specificity for the diagnosis of ITB,and specificity is consistent from study to study.IGRAs may be considered as a supplementary method in the differential diagnosis of ITB from CD.

Objective To study the antagonism of glutathione(GSH) and taurine on acute oxidative damage caused by mercury(Hg). Methods 32 Wistar rats were randomly divided into four groups. The rats of control group were given 0.9% saline by subcutaneous injections. The rats in mercuric chloride (HgCl2) group were subcutaneously injected with 2.5 mg/kg HgCl2. Rats of the other two groups were pretreated with 3 mmol/kg GSH and 4 mmol/kg taurine, respectively and two hours later injected subcutaneously with 2.5 mg/kg HgCl2. Urine creatine and mercury contents were determined; mercury level, contents of GSH, MDA and GSH-Px in liver and kidney were evaluated. Results Compared with the control, urine mercury level, level of mercury in liver and in the renal cortex, contents of GSH, MDA and GSH-Px in kidney in the group treated with 2.5 mg/kg HgCl2 were significantly increased. In the rats pretreated with GSH and taurine, contents of MDA in kidney were significantly decreased compared with those treated with mercury only. The levels of GSH-Px in kidney in the group pretreated with GSH and taurine were significantly higher than that not only in the mercury group but also in the control. Compared with the mercury group, levels of mercury in urine and liver in GSH pretreated group were distinctly reduced. Conclusion Pretreated with GSH and taurine have certain protection for the acute oxidative damage caused by mercury.

Obesity often results when regular caloric intake exceeds the energy expenditure. Hypothalamus is the center that regulates feeding and energy balance inside the body, especially the lateral hypothalamic area (LHA) and ventromedial nucleus (VMN). Acupuncture-moxibustion has achieved significant progress in treating simple obesity, and the relevant studies have revealed the central action mechanism underlying the treatment. By reviewing the literatures associated with the mechanism studies on acupuncture-moxibustion for simple obesity, this article is going to provide clinical and scientific guidance for the treatment of simple obesity with acupuncture-moxibustion.

Objective To investigate the clinical value of serum VEGF levels in the diagnosis and treatment of colon cancer.Methods Serum VEGF was detected by ELISA,and CEA and CA199 concentration were detected by CLEIA in 66 patients with colon cancer,55 patients with colon benign diseases and 50 health persons.The value of individual and joint detection for VEGF in colon cancer was evaluated.Analysis had been done on relationships between serum VEGF and pathology,treatment effects and prognosis.Results The levels of serum VEGF in colon cancer group [(318.5±148.6) ng/L] were significantly higher than those in control group [(125.7±49.4) ng/L] and benign colon diseases [(136.9±52.6) ng/L] (t =8.830,8.805,all P < 0.01).There was a positive correlation between serum levels of VEGF and depth of tumor size,tumor invasion,lymph node metastasis and TNM stage (P < 0.01).The susceptibilities of VEGF,CEA,CA199 were 61%,45 %,53 %.The sensitivity of detection was improved to 86 % when the combined detection of VEGF,CEA and CA199 (x2 =11.237,P < 0.01).The serum levels of VEGF in patients with colon cancer was significantly decreased after treatment in the 3,7,10 day compared with that before operation [(272.3±88.1),(236.8±77.4),(173.1±59.9) vs (318.5±148.6) ng/L,t=2.173,P < 0.05; t =3.961,P < 0.01; t=7.464,P < 0.01],respectively.Conclusion The VEGF was related to the onset and progression and metastasis of colon cancer.It has clinical significancy for diagnosis of colon cancer and judgment of curative effect and prognosis.

Objective To investigate the location and expression of hypoxia inducible factor (HIF) subunits in the remnant kidney of 5/6 nephrectomy rats. Methods Remnant kidneys were produced in adult male SD rats by 5/6 nephrectomy. The renal function and histopathological changes were evaluated at week 1, 2, 4, 6, 8 and 12 after operation. Tissues of remnant kidneys were collected to detect the location and expression of HIF-1α and HIF-2α by immunohistochemistry staining and Western blotting. The mRNA levels of HIF targeted genes vascular endothelial growth factor (VEGF) and heme oxygenase-1 (HO-1) were determined by RTPCR. Results (1) 5/6 nephrectomy rats underwent one week of acute renal failure at first[Scr (122.8±22.1) μmol/L] and then developed compensative chronic renal failure [(66.0±3.7)-(66.4±8.4) μmol/L], but the level of Scr increased quickly after week 6 [(66.4±8.4)-(127.8±22.7) μmol/L],concomitantly with progressive tubulointerstitial fibrosis in remnant kidney cortex. (2) In cortex, HIF-1α was expressed only in the atrophic and dilated tubular cells while HIF-2α was located in endothelial, interstitial fibroblasts, and vascular smooth muscle cells. The semiquantitative results of imunohistochemistry and Western blotting revealed that HIF-1α and HIF-2α were both gradually up-regulated during the early stage of remnant kidney, peaked at week 4 and 6, and then gradually down-regulated. (3) The mRNA levels of HIF targeted genes VEGF and HO-1 transiently peeked at week 4 and 6, and then decreased gradually. Conclusions The increased stabilization of HIF-αprotein and transcription of HIF targeted genes at the early stage of this model is a compensation reaction towards hypoxia. The mechanism of decreased expression of HIF-α at the end stage of chronic kidney disease deserves further investigation.

Objective To investigate the efficacy and safety of Minilase-S on patients with dyspepsia.Methods A randomized,placebo-controlled,double blind and multicenter study was conducted.Two hundred and forty patients with dyspepsia symptoms(anorexia,fullness,abdominal discomfort and distension)were collected according to total symptom scores over 20 with visual analog scales.Each patient was randomly received either Minilase-S(2 capsules t.i.d)or placebo(2 capsules t.i.d)for 2 weeks.The symptoms scores were evaluated at treatment week 1,week 2,and 1 week after discontinued therapy.Results Two hundred and sixteen patients(105 patients in Minilase group and 111 patients in placebo group)finished the study.There was no difference in demographic data,anorexia,fullness,discomfort and distension score and the total symptom score between two groups.However,at treatment week 1,week 2 and 1 week after discontinued therapy,symptoms and total symptom score were significantly decreased in Minilase-S group compared to placebo group(all P value<0.05).The total effective rates in treatment week 1,week 2 and 1 week after discontinued therapy were 64.76%,77.05%and 66.99%,respectinely,which were higer that those in placebo group(27.93%,37.84% and 29.36%,respectively)(P<0.05).There was no severe side effects in both Minilase-S and placebo groups.Conclusions Minilase-S can significantly improve symptoms in patients with dyspepsia,which may be as one choice in the management of dyspepsia or in combined therapy.
