Objective To investigate the effect of Tanreqing injection assisted ganciclovir on children with respiratory syncytial virus pneumonia . Methods 145 cases of RSVP pediatric patientsin from February 2013 to January 2016 in our hospital were retrospectively chosen,according to different drug regimen,they were divided into two groups,the contronl group of 71 cases with ganciclovir injection treatment and study group of 74 cases,with Tanreqing injection treatment on the basis of the contronl group.The blood gas analysis was performed on the arterial blood of the two groups before treatment and 7 and 14 days after continuous administration.The changes of blood gas indexes (pH,PaO2,PaCO2) were compared.The lung rales, wheezing, fever, cough, wheeze disappearance of time and side effects of the children were recorded.Results After 7 and 14 days of treatment, the Ph of blood gas parameters in the study group were (7.38 ±0.21) and (7.41 ±0.26), the level of PaO2 were (96.45 ±4.06) mmHg and (98.84 ± 5.27) mmHg,which were significantly higher than those of the control group (P<0.05);the level of PaCO2 in the study group were(45.02 ±4.23) mmHg and (41.26 ±3.16) mmHg, which were significantly lower than those in the contronl group (P<0.05).The rale resorption time in the study group was (4.47 ±1.06) days, the duration of wheezing subsided was (5.03 ±0.43) days, the duration of wheezing was (4.89 ±0.72) days, the duration of fever subsided was (2.46 ±0.32) days, the duration of cough was (8.41 ±1.54) days,were significantly lower than the control group(P<0.05).The adverse reaction rate in the study group was 8.11%, significantly lower than that in the control group 21.13%(P<0.05).Conclusion The combination of Tanreqing injection combined with ganciclovir has a good effect on children with RSVP , and can significantly shorten the time of clinical evidences such as wheezing, wheezing and pulmonary rales, and improve the blood gas level in children,reduce adverse reactions.

To compare the diagnostic value of high-resolution uhrasonography (HR-US) with nerve conduction study (NCS) in patients with clinically defined carpal tunnel syndrome (CTS),a prospective study was conducted on 37 consecutive patients investigated for sensory hand symptoms. With the clinical diagnosis of CTS as gold standard,NCS showed higher diagnostic sensitivity (80％)than ultrasound (61％) (P =0.047 ).The positive predictive value of HR-US for CTS was 100％.The results indicated that HR-US could be used as a screening method for majority of clinically suspected CTS patients and only for those with negative HR-US results.

Objective To analyze the antibody titer value of indirect haemagglutination test(IHA)in 135 confirmed acute schistosomiasis patients,so as to provide the evidence for improving the diagnosis and treatment of acute schistosomiasis. Meth-ods A total of 135 acute schistosomiasis inpatients were selected from 2001 to 2006. They all received the IHA antibody titer de-tection,and the correlation among the age,incubation period,and hospitalization days was calculated. Results The antibody titers of IHA were higher than 1:320 in all the cases. The percentages of 1:640,1:1280,1:2560,1:5120 and 1:10240 were 1.48%,28.15%,35.56%,20.00%,and 14.81%respectively. The mean age was(47.70 ± 14.58)years,average incuba-tion period was(38.03 ± 4.59)days and mean hospital stay time was(15.08 ± 3.79)days. The antibody titer value had no corre-lation with the age distribution(r=0.109,P>0.05). There was a negatively correlation between the antibody titer value and in-cubation period,(r=-0.558,P<0.01),there was a positive correlation between the antibody titer value and hospitalization time(r=0.791,P<0.01),and there were significant differences among different groups(F=17.07,64.53,both P<0.01). Conclusions The antibody titer of acute schistosomiasis cases detected by IHA is 1:640 and above. There is no correlation be-tween the antibody titer value and age,but the antibody titer value is higher,the incubation period is shorter and hospitalization time is longer.

Traditional atraumatic restorative treatment(ART) induces more successive diseases in the treatment of deciduous caries. Ignoring the disinfection and caries-affected dentin's remineralisation are the main reasons of such problem. Nowadays, Ozone-Remineralisation therapy has become one of the steps before restorative treatment. However, there is no quantitative standard to evaluate this therapy. Some researches had shown that the laser-fluorescent device (DIAGNOdent, Dd) has the advantages in monitoring caries treatment. We use DIAG-NOdent to monitor the effect of OZone-Remineralisation therapy before filling the restoration in the caves in this study, however, the results is delievered that DIAGNOdent has little advatages in monitoring the effect of this new therapy, because the data of DIAGNOdent had a large fluctuation.

Objective To establish a model for studying CD8+ cytotoxic T lymphocyte proliferation in vitro and to screen traditional Chinese drugs (TCDs) with immunosuppressive effects.Methods Spleen tissue was isolated from mice,and made into single cell suspensions followed by separation of CD8+ T lymphocytes with specific antibodies.Then,the CD8 + T lymphocytes were seeded into anti-CD3/CD28 antibody-coated 96-well plates and cocultured with the extracts of 23 TCDs (100 mg/L) separately for 96 hours.Those ceils cultured with and without the presence of anti-CD3/CD28 antibody alone served as the positive control and negative control respectively.The 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium,inner salt (MTS) assay was performed to evaluate the proliferation of cells and to select the top four TCDs with the strongest inhibitory effect.The relationship between the inhibitory effect and TCD concentrations was further assessed for the four selected TCDs.Enzyme-linked immunospot (ELISPOT) assay was carried out to estimate the influence of the four TCDs on the secretion of interferon (IFN)-γ by CD8+ T lymphocytes induced by anti-CD3/CD28 antibodies.Statistical analysis was done by nonparametric rank sum test.Results Of the 23 TCDs,14 significantly inhibited the proliferation of CD8+ T lymphocytes (all P ＜ 0.05),of which,Rhizoma Coptidis,Radix Scutellariae,Radix Aucklandiae and Rhizoma Curcumae Longae displayed the strongest inhibitory capacity with the 50％ inhibitory concentration being 25,35,50 and 60 mg/L respectively,and the 100％ inhibitory concentration being 200,100,200 and 200 mg/L respectively.The anti-CD3/CD28 antibody-induced secretion of IFN-γby CD8+ T lymphocytes was markedly suppressed by Radix Scutellariae,Radix Aucklandiae and Rhizoma Curcumae Longae at the concentration of 100 mg/L,but not by Rhizoma Coptidis at this concentration.Conclusions A model for studying the proliferation of CD8+ T lymphocytes is successfully developed in vitro,and four TCDs with strong inhibitory effects on the proliferation of CD8+ T lymphocytes have been screened out with this model.
