Objective To evaluate the efficacy of stellate ganglion block ( SGB) in the treatment of ischemic optic neuropathy ( ION ) as compared with that of steroids. Methods Eighty-two eyes were involved in seventy patients with ION. The patients were randomly assigned to receive either steroids (dexamethason 15 mg iv q.d. for 5-10 days followed by peroral prednisone 20 mg q.d.) ( n = 34, 38 eyes) or ipsilateral SGB (2% lidocaine 2-3 ml q.d. 10-15 days) ( n = 36, 44 eyes). The criteria for judging the efficacy of the treatment were changes in visual acuity, ocular fundus, visual field and visual evoked potential (VEP) . The effectiveness of the treatment was divided into four grades : excellent, good, improved and no effect. Results In steroid group the results of treatment were rated as excellent for 10, good for 12, improved for 3 and no effect for 13 eyes (the overall success rate was 65.8%), while in SGB group the results were rated as excellent for 15, good for 14, improved for 5 and no effect for 10 eyes ( the overall success rate was 77.3 % ). In patients who were successfully treated, the visual acuity improved, the pale edema of optic papilla was disappearing and the color and blood vessels of retina were returning to normal. The latent time of VEP P100 was significantly shortened and the amplitude increased in both groups. Conclusion SGB is a safe, reliable and effective method of treatment for ION.

Objective To study the distribution and changes of the purulent meningitis in gender,age,region,season and pathogens in children during the past 20 years.Methods All the basic clirical features of purulent meningitis patients less than 17 years old in Children's Hospital of Chongqing Medical University from Jan.1993 to Jan.2013 were analyzed retrospectively.A total of 1 855 patients were divided into 2 groups according to their date of admission.Group A included 666 patients admitted from Jan.1993 to Dec.2002,and group B included 1 189 cases admitted from Jan.2003 to Jan.2013.Then,they were divided into 5 groups according to their ages,including neonate group,＞ 1 month-1 year old aoup,＞ 1-3 years old group,＞ 3-10 years old group,＞ 10-17 years old group.Results Of the 1 855 cases,there were 1 054 cases (56.82％) admitted in the spring and summer,and 1 123 cases (60.54％) were younger than 1 year of age.The ratio of male to female cases was 1.82 to 1.00 and that of country patients to urban patients was 1.40 to 1.00.The distributions were female patients (443 cases,37.26％),urban patients (517 cases,43.48％),and the ratio of patients admitted in the autumn (265 cases,22.29％) and patients younger than 1 year of age (606 cases,50.97％) in group B,which were significantly higher than those [215 cases (32.28％),256 cases (38.44％),102 cases (15.32％),272 cases (40.84％)] of group A (x2 =4.62,4.47,25.51,25.52,all P ＜ 0.05).The predominant isolated bacteria from cerebrospinal fluid were coagulase negative staphylococcus (43/196 cases,21.94％),Streptococcus pneumoniae (32/196 cases,16.33％),Neisseria meningitidis (17/196 cases,8.67％) and Escherichia coli (15/196 cases,7.65％).Coagulase negative staphylococcus and Escherichia coli both accounted for higher rates of pathogenic bacteria in 1 year old than that of pathogenic bacteria more than 1 year old (x2 =4.57,14.37,all P ＜ 0.05),while Streptococcus pneumoniae and Neisseria meningitidis both had higher rates of pathogenic bacteria more than 1 year old and more than 3 years old,respectively (x2 =14.93,19.76,all P ＜ 0.05).Onfly cases in group B with Streptococcus pneumoniae were higher than those in group A (x2 =11.78,P ＜ 0.05),while the other common bacteria in each age group were of no difference between group A and group B.Conclusions There had been some changes in the epidemiological distribution of purulent meningitis during the past 20 years.The main risk factors were male in gender,patients in rural areas,onset in the spring or summer and infants in early age.The predominant isolated bacteria from cerebrospinal fluid were some opportunistic pathogens,including coagulase negative staphylococcus,Streptococcus pneumoniae,and Escherichia coli.Streptococcus pneumoniae meningitis was increased during the past 10 years.

Objective To investigate the relationship between molecular biological markers and recombinant human endostatin targeted therapy in non-small-cell lung cancer(NSCLC).Methods 68 cases patients with non-small-cell lung cancer to meet the requirements were randomly divided into group A (n=34)and group B (n=34).Group A received docetaxel and cisplatin(DP)and gefitinib;group B received recombinant human endostatin on the base of group A.The biological markers species,such as,EGFR,KRAS,VEGF,BRCA1,EML4-ALK,ERCC1,β-tubulin and CD3 were detected by immunohistochemical.The types of population for different programs were summarized according to the expression of biological markers and progression free survival (PFS)of the two groups. Results Group B median PFS was significantly longer than that in group A;no matter low or high expression of VEGF and BRCA1,group B median PFS was significantly longer than that in group A(P<0.05);high expression of ERCC1,KRAS,EML4-ALK andβ-tubulin,group B median PFS was significantly longer than that in group A(P<0.05);low expression of EGFR and CD3,group B median PFS was significantly longer than that in group A (P<0.05 ).Conclusion No matter low or high expression of VEGF and BRCA1 ,low expression of KRAS, ERCC1,EML4-ALK and β-tubulin and high expression of EGFR and CD3 in patients with non-small cell lung cancer may be more sensitive to the treatment of DP and gefitinib combined with recombinant human endostatin.

Objective To study the effect of omethoate on the activity of characteristic enzymes in mouse testicles and the antagonism of teapolyphenol. Methods 80 Kunming male mice were divided into 8 groups, omethoate was given by gavage: the control group given 0.9% NaCl solution, a group given teapolyphenol of 180 mg/kg bw, three groups given omethoate of 1, 2 and 4 mg/kg bw respectively, three groups given teapolyphenol of 180 mg/kg bw and two hours later followed by omethoate of 1, 2 and 4 mg/kg bw respectively. The gavages were conducted for 6 consecutive days. The activities of the characteristic enzymes (AKP, ACP, LDH and LDH-x) in mouse testicles were measured by biochemistry method and variance analysis was done with the SPSS 11.0 software. Results As omethoate dose increased, the body weight and the testicle weight decreased obviously, the activities of AKP, ACP, LDH in mouse testicles significantly increased compared with the control. Given teapolyphenol 2 hours before given omethoate, the significant changes as above did not emerged. Conclusion Teapolyphenol has an antagonism against the adverse effects of omethoate on the activity of characteristic enzymes in mouse testicles.

Objective To investigate the feasibility of establishing tumor model of MDR in rabbit liver with VX2 tumor induced by adriamycin. Methods 20 white rabbits were randomly divided into 4 groups with 5 for each. Liver tumor was established with VX2 tissue together with or without MDR-induced for their formations. VX2 tumor without MDR-induced was included in group A and B ,while MDR-induced tumor was employed in groupe C and D. Contrast enhanced CT was performed three weeks later to assess the volume of tumors. 4 mg adriamycin (dilute with 2ml of saline) was infused in group A and C via the common herpatic artery directly and respectirely; whereas same amount of saline adminisfrated through the same way for group B and D. Follow up CT was performed one week later to assess the change of tumor. Apoptosis rate was analized for each group by means of flow cytometry (FCM). Results No significant difference was found between the 4 groups three weeks after the establishment in term of tumor volume. Follow up CT performed 1 week after the treatment showed the volume increase of tumor for all groups. Group A was significantly lower than the other three groups in tumor growth rate (P0.05). The apoptosis rate of group A detected by FCM was significantly higher than the other three groups(P0.05). Conclusion Implanted liver tumor with VX2 induced by, adriamycin in tumor carrying rabbits possesses the character of drug resistance, which is profitable to be a liver tumor model of MDR for the therapeutic trial.
