Objective To evaluate the efficacy and safety of XELOX chemotherapy combined with Chinese herbal medicines in patients with obstructive colorectal cancer.MethodsA total of 70 patients with obstructive colorectal cancer were recruited and divided into a XELOX treatment group and a combined treatment group, 35 in each group. The XELOX treatment group received XELOX chemotherapy, while the combined treatment group were received XELOX chemotherapy combined with Chinese herbal medicines. All patients received a 3-week treatment as a cycle, and for 4 cycles. The outcomes were Karnofsky performance status (KPS) and the Zubrod-ECOG-WHO Scale (ZPS). Adverse effects were recorded.ResultsAfter the treatment, the clinical symptoms score (1.62 ± 0.21vs. 2.12 ± 0.31;t=7.900,P<0.01) and ZPS score (1.07 ± 0.33 vs. 2.88 ± 0.41;t=20.346,P<0.01) in the combined treatment group were significantly lower than those in the XELOX treatment group, but the KPS score was significantly higher (93.42 ± 5.56vs. 86.43 ± 5.93;t=5.087, P<0.01). The follow-up showed that the 3-year survival rates in the combined treatment group was significantly lower than those in the XELOX treatment group (80.00%vs. 57.14%;χ2=4.242,P=0.039). The incidence of leukopenia (11.43%vs. 34.29%;χ2=3.970,P<0.05), anemia (5.71%vs. 22.86%;χ2=4.200,P<0.05), nausea/vomiting (8.57%vs. 28.57%;χ2=4.629,P<0.05), and diarrhea (2.86%vs. 20.00%;χ2=5.081,P<0.05) in the combined treatment group were significantly lower than those in the XELOX treatment group. Conclusion XELOX chemotherapy combined with Chinese herbal medicines can improve clinical symptoms, performance status, and alleviate adverse effects in patients with obstructive colorectal cancer.

Aim To discuss the application of tissue spontane-ous fluorescence for draw focal cerebral ischemia reperfusion in-jury in rats based on specific fluorescence detection technology. Methods The change of spontaneous fluorescence WAS COM-PARED between the brains of normal rats and those of rats with draw focal cerebral ischemia-reperfusion injury and an quantita-tive analysis was then made. Result The results showed that spontaneous fluorescence of brain tissue for focal cerebral ische-mia reperfusion injury changed significantly. Spontaneous fluo-rescence signal of injury considerably enhanced. The fluores-cence signal which was quantified by IVIS had significant statisti-cal significance compared with normal brain tissue, P <0. 05. Conclusion Our research shows that spontaneous fluorescence of brain tissue enhances obviously after focal cerebral ischemia-reperfusion injury. Our research provides a method for the re-search and evaluation of focal cerebral ischemia-reperfusion inju-ry model in rats.

Objective: To evaluate the protective effect of alanyl-glutamine dipeptide (Ala-Gin) on different acute gastric ulcer models in rats and investigate its possible mechanisms. Methods: The gastric ulcer in rats was induced by waterimmersion restraint stress, ethanol and pylorus ligation. On each gastric ulcer model, sixty SD rats were randomly divided into six groups including the gastric ulcer control group, cimetidine (0.1 g/kg) and marzulene-S (1.0 g/kg) treatment groups,as well as 0.5, 1.0 and 1.5 g/kg Ala-Gin treatment groups. Before the gastric ulcer, different doses of drugs were administered intragastrically,once a day for 3 days. Ulcer index, gastric acid, gastric juice value, gastric acid, free acid, total acid and pepsin activity were used to evaluate and compare the protective effect of Ala-Gin and other anti-ulcer drugs. Results: Ala-Gin significantly reduced the gastric ulcer index in all giving dose (P<0.01) and its protective effect increased significantly with the climbing dose. In all three gastric ulcer models,the anti-ulcer effects of 1.0 and 1.5 g/kg Ala-Gin treatment groups were equal to that of marzulene-S. In addition, Ala-Gin also markedly inhibited the secretion of free acid (P<0.01)and decreased the activity of pepsin (P<0.05) on pylorus ligation gastric ulcer rats. Conclusion: Ala-Gin has obviously anti-ulcer effect on different experimental gastric ulcer models. Except for the known protective effect on gastric mucosa, its anti-ulcer mechanisms may be related to its inhibitory effect on gastric acid and pepsin.

Objective To explore the effects of different period of insulin-like growth factor-1(IGF-1)on B cell lymphoma/leukeamia-2 gene(BCL-2)and BCL-2 associated X protein(BAX)of myocard in mice with viral myocarditis.Methods Male Balb/c mice were randomly divided into control group,coxsackie viral B3(CVB3)infection group(infection group),IGF-1-treated group in earlier stage(0-6 d)and acute stage(7-13 d),injected IGF-1 of exogenous in abdominal cavity [30 ?g/(kg?d)].Animals were killed at the 14 day.The immunohistochemical studies and medical imagine analysis system were performed to evaluate the expression of BCL-2 and BAX in myocardial tissue.Results In infection group,the expression of BCL-2 reduced and BAX increased than those of control and treatment group(Pa
