Objective To study the effect of microecologic modulator combined with antibiotic in treatment of infantile diarrhea.Methods 150 children with diarrhea in our hospital were selected as the research subjects,they were randomly divided into observation group and control group,75 cases in each group.The observation group used tyrosine aureus triple viable bacterial combined with amoxicillin therapy,the control group received lactasinum biofermin, vitamin for oral treatment.The curative effect,clinical symptoms and inflammatory factors TNF -ɑ,IL -6,IL -10 changes after treatment for 2 months were compared in the two groups.Results The vomiting,fever,abdominal pain relief time and length of hospital stay in the observation group were (5.12 ±0.52)d,(1.52 ±0.33)d,(1.32 ± 0.41)d,(4.73 ±0.55)d,(5.95 ±0.52)d respectively,which of the control group were (10.33 ±0.64)d,(2.62 ± 0.47)d,(2.21 ±0.32)d,(10.06 ±1.67)d,(11.05 ±1.42)d respectively,which of the observation group were significantly shorter than the control group.The effective rate of the observation group was 97.33% (73 /75),which of the control group was 84.00% (63 /75),the difference between the two groups was statistically significant(χ2 =8.324,P <0.05).Before treatment,the TNF -ɑ,IL -6,IL -10 levels had no obvious differences between the two groups,after treatment,those in the observation group were (2.08 ±0.24)ng/mL,(94.67 ±10.75)ng/mL,(7.58 ± 0.88)ng/mL respectively,those in the control group were (2.88 ±0.37)ng/mL,(128.55 ±17.53)ng/mL,(40.55 ± 1.12)ng/mL respectively,and the levels of the observation group were better than the control group,the differences were statistically significant (t =6.327,5.694,4.156,all P <0.05 ).Conclusion Microecologic modulator combined with antibiotic in treatment of infantile diarrhea can significantly shorten the recovery time of clinical symptoms,reduce inflammation,improve the treatment effect,it is worthy of clinical popularization and application.

Objective To observe the protective effect on retinal ganglion cells (RGC) and the safety of intravitreal injected acteoside in rats.Methods A total of 50 male Sprague Dawley rats with the weight of 190-210 g were used in this study.Fifteen rats were used for safety experiment of intravitreal injection of acteoside.The rats were divided into group A,B,C,control group and blank group,three rats in each group.The rats in group A,B and C were received intravitreal injection of 5 μl acteoside at the concentration of 1,2,and 5 mg/ml,respectively.Phosphate buffer solution (PBS) was injected in rats of control group.No treatment was performed for blank group.The retinal structure was examined by hematoxylin-eosin (HE) staining of retinal frozen sections at one,two and three weeks after injection.The retinal ultrastructure was examined by ultrathin section under transmission electron microscope at one and three weeks after injection.Others 35 rats were used for experiment of protective effect of acteoside on RGC.The rats were divided into operation group A and B (n=8),sham operation group C and D (n=8),and blank group (n=3).The optic nerve of rats in operation group was clamped for 10 seconds after optic nerve exposure,while the optic nerve of rats in sham operation group was exposed only.The rats in operation group A and B were received intravitreal injection with 5 μl acteoside (1 mg/ml) and 5 μl PBS respectively.The rats in sham operation group C and D were received intravitreal injection with 1 μl acteoside (1 mg/ml) and 1 μl PBS respectively.No treatment was performed for blank group.The retinal structure was examined by HE staining of retinal frozen sections at one,two and four weeks after injection.Immunohistochemistry was used to measure the expression of growth associated protein 43 (GAP-43).RGC apoptosis was assessed by the terminal deoxynucleotidyl transferase mediated dUTP-biotin nick-end labelling (TUNEL) method.Software of SPSS 13.0 was used for the data statistical analysis in this study.Results In the safety experiment of intravitreal injected acteoside,there was no abnormity of cornea,anterior chamber,lens,vitreous cavity and retina after injection.At one,two and three weeks after injection,the retina structure was normal without significant apoptosis,necrosis and inflammatory cell infiltration.The ganglion cell layer showed slightly edema; there was no obvious change of retinal ultrastructure after injection of acteoside with 5 mg/ml and 2 mg/ml,but slight change with the format of 1 mg/ml.Transmission electron microscopy showed that intravitreal injection of 5μl acteoside at the concentration of 2 or 5 mg/ml can induce significant changes of micro-structures of retina,while injections at 1mg/ml can only induce minor changes.In the experiment of protective effect of acteoside on RGC,light microscope revealed that the cell showed typical changes of apoptosis in operation group,but not in sham operation group and blank group.At the first and second week after injection,compared with the sham operation group and blank group,the RGC number was decreased in operation group.The difference of RGC numbers between operation group A and B was statistically different (F=26.206,P＜0.05).The RGC numbers in operation group continues to decrease at the fourth week after injection,there was obvious difference compared with the first and second week after injection (F=17.364,P＜0.05),but there was no difference of RGC numbers among sham operation intra-group and between sham operation group and blank group at all the time points.Immunohistochemistry showed that at the first week after injection,the integrated absorbance (IA) value in operation group was higher than that in other groups (F=33.466,P＜0.05) ; there was no difference of IA value between operation group A and B.At the second week after injection,IA value in operation group A had slightly declined,but higher than that in operation group B (F=14.391,P＜0.05).At the fourth week after injection,IA value in operation group A declined further,but also higher than that in other groups (F=4.178,P＜0.05).TUNEL showed that on the first week after injection,RGC apoptosis rate in operation group was increased than that in other groups (F=15.365,P＜0.05).At the second week after injection,RGC apoptosis rate in operation group was decreased,and it in operation group A was lower than that in operation group B (F=15.365,P＜0.05).At the fourth week after injection,RGC apoptosis rate in operation group was decreased obviously,there was no difference compared with other groups (F =2.057,P ＞ 0.05).There was no difference of RGC apoptosis rate between sham operation group and blank group at all the time points.Conclusion Intravitreal injection of 5 μl acteoside (1mg/ml) is safe for rat retina,and can up-regulate GAP-43 expression and inhibit RGC apoptosis in optic nerve crush rats.

Objective To investigate the effect of cetuximab combined with FOLFOX4 chemotherapy on expressions of cancer suppressor gene PTEN and P13K in colon cancer tissue of elderly patients.Methods 62 cases of elderly patients with colon cancer from October 2013 to July 2015 in our hospital were selected and divided into two groups according to the different therapy.The control group (n=27) received pure FOLFOX4 chemotherapy and treatment group(n=35)received cetuximab on the basis of FOLFOX4 chemotherapy, with a consecutive treatment of 4 courses.The clinical curative effect and expressions of PTEN and P13K in colon cancer tissue were compared between two groups.Results There were no significant difference in effective rate and disease control rate between treatment group and control group (51.4% vs.44.4%,χ2 =0.298,P=0.585;80.0%vs.62.9%,χ2 =2.223, P=0.136 ).After treatment, the cells positive rate of PTEN in treatment group was higher than that in control group post-treatment (82.86%vs.59.26%, P<0.05), and the cells positive rate of P13K in treatment group was lower than that in control group (37.14%vs.62.96%, P<0.05). Conclusion Cetuximab combined FOLFOX4 chemotherapy regimen could increase expression of PTEN and reduce P13K expression, which effect is remarkable in the treatment of elderly colon cancer.

Objective To build the theoretical system model and research assessment indicators for equalization of basic medical and health services of both urban and rural residents.This aims at providing a theoretical and empirical basis for advancing basic medical health system covering rural and urban residents.Methods Literature research and Delphi expert consultation are used to build the indicator model and structure.The extremal standard method,health resources sharing by geography method,Gini coefficient method and other statistical analysis were used for an empirical analysis and test in an eastern provincial capital city.Results The indicator system comprises three dimensions of opportunity,process and result,as well as seven second-level indicators of health financing,resource allocation,accessibility etc.and twenty-seven third-level indicators.The grand mean value of the urban and rural regional indicators for H city in 2010 was calculated as 63.53,while the mean values for urban and rural were 74.75 and 45.58 respectively.Conclusion The assessment indicators focus on three combinations:basic public health services and basic medical services,service supply and demand,as well as the number and quality of services.This approach can help with the assessment of equalization of basic medical and health service for urban and rural areas and policy making.
