At present, the level of diagnosis and treatment of early gastrointestinal cancer has a larger gap between China and developed countries. In recent years, the advent of new endoscopic imaging techniques has improved the detection rate of early gastrointestinal cancer. Along with this, endoscopic submucosal dissection(ESD) enables radical resection for early cancer. In this article, we discuss how to improve the level of endoscopic diagnosis and treatment of early gastrointestinal cancer.

OBJECTIVE: To observe the plasma metabolic changes of rats after acute hepatic injury induced by CCl4 and the regulating action of Erzhi pills (EZW, traditonal Chinese medicines) on abnormal metabolism, and to find the potential biomarkers. And to explore the mechanisms of Erzhi pills in treatment of acute hepatic injury induced by CCl4. METHODS: Endogenous metabolites in plasma were determined with RRLC-Q-TOF/MS. RESULTS: Nine potential metabolic biomarkers were identified qualitatively. Two metabolic pathways were identified using ingenuity pathway analysis (IPA). CONCLUSION: Changed metabolites can be recovered by Erzhi pills in different degrees, and the treatment effect of Erzhi pills may be related with the regulation of two metabolic pathways. Unique pathway analysis may be effective in drug-target identification, which helps to further understand mechanism of drug action, and improve research efficiency.

Objective To investigate the effects of colon hydrotherapy on lowering body temperature and serum enzymes as well as inflammatory cytokines of dogs with heat stroke.Methods 14 dogs were randomly devided into 2 groups,7 for each,as colon hydrotherapy group and conventional therapy group.After the reproduction of heat stroke model was finished(core temperature reached 43℃,maintaing for 10min),cooling therapy was commenced on dogs in circumstance with temperature at 23℃ and 65% of humidity.Conventional therapy group was lowered temperature by ice bags placed on conducting arteries,and the colon hydrotherapy group was by colon way therapeutic machine,the temperature of therapeutic liquid was maintained between 37℃~38℃.Cooling was finished while temperature in dogs reduced to 38℃.The periods of time for lowering body temperature in both groups were compared.Alanine aminotransferase(ALT),aspartate aminotransferase(AST),lactate dehydrogenase(LDH)and creatine kinase(CK)were determined before heat stroke(0h),and 6h,24h and 48h after heat stroke.Interleukin-1?(IL-1?),Interleukin-6(IL-6)and tumor necrosis factor ?(TNF-?)were determined by radioimmunity assay.Results Body temperature lowering time in dogs with colon hydrotherapy were 92.9?9.5min,which was significantly shorter than that of conventional therapy group(123.4?11.6min,P0.05).IL-1? in colon hydrotherapy group at 6h,24h and 48h after treatment were significantly lower than those in conventional therapy group(P

OBJECTIVE: To study the excretion profile of schizonepetin in rats. METHODS: An HPLC-UV method was developed and validated for the determination of schizonepetin in urine, feces and bile. Using this method, the excretion features were studied in rats after oral and intravenous administration. RESULTS: There was significant difference in the excretion percentages of schizonepetin between male and female both in rat urine and bile for oral administration and in urine for intravenous administration. No significant difference was observed in the excretion of schizonepetin through feces for the two administration routes. CONCLUSION: The amount of schizonepetin recovered from urine, feces and bile after administration is very low, indicating that schizonepetin is mainly excreted in the form of metabolites.

Objective To detect the expression of osteopontin (OPN) in cervical local tissues of patients with chronic cervicitis, cervical intraepithelial neoplasia (CIN), cervical cancer. To investigate the possibility that OPN is used as tumor marker of cervical cancer. Methods The expression of OPN in 25 cases of chronic cervicitis, 18 cases of CIN and 21 cases of cervical cancer was detected by immuohistochemistry SP method. Results The positive expression rates of OPN in the chronic cervicitis, CIN and the cervical cancer had a rising trend (48 %, 77.78 % and 80.95 %, respectively) and their differences had statistical significant (P <0.05). The OPN expression level in cervical cancer had no statistical correlation with age, tumor size, clinical stage and other clinical pathological features (P >0.05). Although OPN expression level in cervical cancer wasn' t related with tumor clinical stage, positive expression rates of OPN had a gradually increased trend along with the clinical stage. Conclusion High expression of OPN is found in cervical cancer and may be related to the occurrence and development of cervical cancer.

Objective To assess the significance of urethral sphincter electromyography (US-EMG) and external anal sphincter electromyography (EAS-EMG) for the diagnosis of multiple system atrophy (MSA).Methods US-EMG and EAS-EMG were performed in 9 patients who were diagnosed as MSA.Duration,motor unit action potentials amplitude,polyphasicity,as well as recruited pattern and amplitude during powerful contraction were recorded and analyzed.Results Among 9 patients who were diagnosed as MSA,7 cases showed neural injury by both US-EMG and EAS-EMG.There was significant difference of electromyographic findings between US-EMG group and EAS-EMG group (average volatility (μV):1063.44 ±499.92 vs 634.89 ±265.07; polyphasic wave:0(0,20％ ) vs 57％ (28％,63％ ) ; t =2.567,P=0.033;t =2.833,P=0.012).Conclusions Although US-EMG may be difficult to perform,US-EMG may have the same specificity as EAS-EMG for the diagnosis of MSA,especially for the diagnosis of MSA patients only with urination disorders,who are involved in Onuf neclear according to some of the abnormal indexes.

Objective To analyze diagnostic evaluation of urethral sphincter electromyography (US-EMGs) for patients with multiple system atrophy (MSA).Methods Totally 15 patients who were diagnosed as MSA were examined as treatment group while 17 non-MSA patients were examined as controls.US-EMGs were performed in the both groups.Spontaneous activities when relax,parameters of motor unit potentials(MUPs) mean duration and amplitude,percentage of polyphasic ware,satellite potential,recruitment potentials and amplitude when strong contraction were recorded and analyzed.Results USEMGs changes of various abnormalities were found in 13 cases (86.7％) in MSA group.There were significant differences of electromyographic findings between the MSA group and control group including MUPs mean duration[(12.79 ±3.18)ms vs (9.49 ± 1.51)ms] and amplitude[(828.53 ±459.89) μV vs (378.76 ± 152.26) μV] as well as recruitment potentials [(11.47 ± 21.55) ％ vs (8.23 ± 10.74) ％] and amplitude [(2.19 ± 1.24) mV vs (0.75 ± 0.42) mV] when strong contraction (all P values ＜ 0.05).Conclusions There is certain value of US-EMGs for the diagnosis of MSA.It could be used as a routine electrophysiological method for the patients who are suspected of MSA.It could be a supplement of externalanal sphincter electromyography.

Objective:To analyze the medication of one patient with ulcerative colitis to provide pharmaceutical care and support for rational drug use in patients with ulcerative colitis. Methods:During the treatment of the patient with severe ulcerative colitis, clin-ical pharmacists analyzed the drugs used by the patient and provided pharmaceutical care for doctors and the patient according to the ex-amination and diagnosis of the patient. Results:The compliance, therapeutic effect and medication safety of the patient were all im-proved by giving clinical drug rationalization suggestions and targeted medication monitoring and education, which fully embodied the necessity of work of clinical pharmacists in the medication of patients. Conclusion:Through case analysis, clinical thinking of clinical pharmacists can be developed to promote rational drug use, avoid adverse drug reactions and achieve optimal effect of drug treatment.

This study aimed to elucidate the effects of different soil water contents on the yield and quality of R.glutinosa.Different soil water contents were adjusted in different periods of growth of R.glutinosa.The yield,content of water extract,catalpol,verbascoside and polysaccharide were determined and analysed by the grey pattern recognition after harvests.The impacts of soil water content from the most important to the least important were medium moisture content (M2),high moisture content (M3),low moisture content (M1) and blank (M4).In the cultivation of R.glutinosa,the soil water content should be remained in the range of 40％-50％ at seedling stage,while 50％-60％ at the stage of root formation and tuber enlargement,and 20％-30％ during harvesting,which can significantly improve the yield and quality of R.glutinosa.
