Objective To explore the characteristics of the interactions between traditional laxative medicine Cannabis Fructus and human gut microflora. Methods HPLC method was used to determine the content of the main unsaturated fatty acids linoleic acid and linolenic acid in Cannabis Fructus Decoction. At the same time, solid culture and liquid culture in vitro anaerobic culture method were combined with 16 S rRNA technology to analyze the interactions between Cannabis Fructus Decotion and human gut microflora. Moreover, the metabolits of linoleic acid and linolenic acid in Cannabis Fructus Decoction by human intestinal microflora were determined using HPLC method. At the same time, the possible conjugated linolenic acid and linoleic acid were determined. Results Cannabis Fructus Decoction promoted the growth of Proteobacteria significantly, which showed that Escherichia-shigella was significantly increased (P < 0.01), but the growth of Bacteroidetes was decreased (P < 0.01), and the content of unsaturated fatty acids linoleic acid and linolenic acid in Cannabis Fructus Decoction were reduced after being incubated with human intestinal bacteria, and the metabolites were conjugated linoleic acid and conjugated linolenic acid. Conclusion The interactions between Cannabis Fructus Decoction and human intestinal microflora are obvious. The Chinese medicine can change the structure of the gut microflora, and the gut microflora can metabolize the drug components. This analysis method partially restores the pharmacokinetics process of the oral administration drug in the human intestinal tract. It could provide a new insight of the mechanism research of Cannabis Fructus.

ObjectiveTo assess the differential diagnostic value of serum intestinal fatty acid binding protein (I-FABP)in distinguishing intestinal ischemia patients from acute abdomen patients.MethodsA total of 151 patients with acute abdomen and 17 healthy controls from the PLA General Hospital were enrolled from November,2009 to August,2011. Serum I-FABP levels were measured by ELISA.According to the ROC curve,the cut-off value,sensitivity,specificity,positive likelihood ratio (PLR),negative likelihood ratio ( NLR),positive predietive value (PPV) and negative predictive value (NPV) were calculated. ResultsOf the 151 acute abdomen patients,there were 24 intestinal ischemia patients and 127 without intestinal ischemia.Serum I-FABP level in intestinal ischemia group [( 109.67 ±48.82) μg/L]was significantly higher than those in patients without intestinal ischemia [(36.78 ± 11.25) μg/L]and healthy controls[(8.33 ±6.25) μg/L]( all P values ＜0.01 ).The serum I-FABP cut-off value for the diagnosis of intestinal ischemia was 87.52 μg/L.Serum I-FABP was efficient in terms of sensitivity (0.762),NPV(0.963),PLR(3.05) and NLR (0.24) in the diagnosis of intestinal ischemia.ConclusionI-FABP is potentially useful for discriminating intestinal ischemia from acute abdomen.

Objective To investigate the clinical treatment of nonpenetrated cornea trauma caused by crops. Methods Clinical data of 128 cases of nonpenetrated cornea trauma caused by crops were retrospectively analyzed. According to the interval time between occurrence of trauma and clinic visiting, the patients were divided into 3 groups:group A (33 cases,<24 h), group B (72 cases, 24 h≤interval time<1 week) and group C (23 cases, ≥ 1 week). The therapeutic effects and prognosis were analyzed. Results There was statistical difference in the incidence of corneal ulcer among group A, group B and group C: 6.1% (2/33), 62.5% (45/72) and 100.0% (23/23), χ2= 52.32, P<0.01. In group B, 12 cases were treated with conjunctival flap covering, 2 cases received keratoplasty and 2 cases undertook enucleation. In group C, 10 cases were treated with conjunctival flap covering, 4 cases received keratoplasty and 2 patients undertook enucleation finally. All the other patients were cured with local debridement and medical treatment. Conclusions Patients with nonpenetrated cornea trauma caused by crops may develop infectious keratitis, and prompt and proper treatment can avoid the secondary infection and improve the outcome. Local debridement in combination with iodophors disinfection can prevent the incidence of infectious keratitis. Conjunctival flap covering is an effective technique in the treatment of corneal ulcer caused by nonpenetrated cornea trauma.

Objective To evaluate the effect of various methods of fecal exfoliated cell testing for screening of colorectal cancer.Methods The stool samples from 814 patients who underwent colonoscopy were collected for fecal exfoliated cell testing using diarrhea feces,twice naturally evacuated feces,magnetic separation or naturally evacuated combined with diarrhea feces.The fecal exfoliated cells were isolated and examined cytologically.The DNA quantitative analysis and gene detection were carried out.Fecal occult blood test was simultaneously performed in twice naturally evacuated feces and naturally evacuated combined with diarrhea feces.Results The sensitivity and specificity of exfoliated cells testing for colorectal Cancer was 66.27%(112 of 169 cases of colorectal cancer)and 99.56%(225 of 226 normal subjects),respectively.There was no correlation of positive rate with differentiations of colorectal cells or Duke's stages(P＞0.05).The nuclear DNA quantitative analysis showed that the sensitivity for detecting cancer was 76.09%for twice naturally evacuated feces and 68.29%for naturally evacuated combined with diarrhea feces,which was superior than diarrhea feces(26.31%)and magnetic separation (43.24%).The positive rate of genes detected in carcinoma tissues concordant with fecal exfoliated cells testing were 83.33%(25/30)for p53,9/10 for APC and 9/10 for K-ras.The sensitivity of cytology was higher than gene detection.The sensitivity of cancer detection was higher in combining exfoliated cells test with fecal occult blood test(93.10%)than exfoliated cells test(73.56%)or fecal occult blood test (80.46%)alone(P＜0.05).Conclusions Fecal exfoliated cells test is an effective method for screening of colorectal cancer.It is the best option for detecting cancer by twice tests of fecal exfoliated cells with liquid-based thin-layer cytological test,and combined with fecal occult blood test.

Objective To investigate the expression of hypoxia inducible factor-1α(HIF-1α)in the transplanted liver in rats and the role of HIF-1α in the JNK signaling pathway.Methods Ninety-six SD rats were randomly divided into normal control(NC)group,autotransplantation(AT)group,hypoxia preconditioning (HP)+ AT group according to simple random sampling method.No treatment was applied to the rats in the NC group except for blood vessel separation.Stable rat models of 70％ AT was established in the AT group.Rats in the HP + AT group were given 8％ oxygen mixed gas for 90 minutes before the operation.The levels of alanine aminotransferase(ALT)and aspartate aminotransferase(AST)were detected at 1,2,12,24 hours after operation,and the expression of HIF-1α in the hepatic tissue,mRNA expression of c-Jun,and protein expression of Cleaved Caspase-3 were detected by immunohistochemical staining,reverse transcription-polymerase chain reaction and Western blot,respectively.All data were analyzed using the analysis of variance or t test.Results The levels of ALT and AST in the HP + AT group were significantly lower than those in the AT group,while higher than those in the NC group at 1,2,12 and 24 hours after the operation(F=2631.371,1177.642,810.383,682.848;743.618,1095.522,375.995,580.613,P ＜0.05).The protein expression levels of HIF-1α in the AT group were significantly lower than those in the HP + AT group,but higher than those in the NC group at 1,2,12 and 24 hours after operation(F = 191.737,284.482,459.419,213.782,P ＜ 0.05).The mRNA expression levels of c-Jun in the HP + AT group were significantly lower than those in the AT group,while higher than those in the NC group at 1,2 and 12 hours after operation(F = 66.211,53.169,9.645,P ＜ 0.05).There was no significant difference in the mRNA expression of c-Jun among the 3 groups at 24 hours after operation(F = 1.100,P ＞ 0.05).The protein expressions of Cleaved Caspase-3 in the HP + AT group were significantly lower than those in the AT group,while higher than those in the NC group at 1,2,12 and 24 hours after the operation(F =23.133,31.158,14.347,29.043,P ＜ 0.05).Conclusion High expression of HIF-1α after HP inhibits apoptosis of hepatic cells and alleviates ischemia reperfusion injury of hepatic tissues by suppressing JNK activation,down-regulating protein expression of Cleaved Caspase-3 after orthotopic liver transplantation in rats.

Objective To explore the impulsivity and aggressivity,and its treatment outcomes of the inpatients with intemet addiction disorder (IAD) by intergration interview. Methods Barratt Impulsiveness Scale ( BIS), Buss Aggressive Scale (BAS) were used to assess the impulsiveness and aggressivity in 58 IAD patients, at the first week and after the point of intergration interview 3 months,54 normal subjects in the control group were conducted by BIS and BAS only when they were recruited. Results ①The intemet addiction group had significantly higher scores on the BIS and BAS total scores than the control group at the first week ( BIS score 99.3 ±15. 1vs 75.0 ± 15.4, t=8.47, P＜0. 01; BAS score 78.3 ±24.4 vs 54.8 ± 17.7, t=5.87 , P＜0. 01 ). IAD group had lower scores on the total scores of BIS-Ⅱ and BAS after intergration interview than before, but the subscales and total scores were higher than those in the control group ( BIS score 86.3 ± 16.6 vs 75.0 ± 15.4, t =4.98, P ＜ 0.01 ;BAS score 66.2 ± 22.6 vs 54.8 ± 17.7, t = 3.65, P ＜ 0. 01 ). ②Total score of SCL-90 in IAD group were significantly correlated with the BAS total score ( r=0. 376, P＜0. 01 ) ,and the decreased SCL-90 total score was also related with the decreased BAS score ( r= 0.508, P＜ 0. 01 ). Conclusion This study suggests that IAD group exhibit more impulsivity and aggressivity than those in the control group. After interview, their impulsivity and aggressivity are significantly decreased, but are still higher than those in the normal control group.
