Community Health Service ( CHS) not only contains the treatment, but also considers the care as its responsibility. Therefore, its character of humanity service can be showed in the practice. However, besides the humanity, CHS needs some reasonable forms such as laws, systems as well, to protect its development and community habitants health. The author thinks that when the humanity and reasonableness conjunct on the solution and prevention for the medical tangle which occurs in the CHS, maybe the medical Ttreatment will come back to its birthday on which it ensured "care and console" as its duty, and it also can decrease the medical danger at length, then serve for the society and benefit for the people.

OBJECTIVE:To study the effect and its mechanism of dexmedetomidine(Dex)on inflammatory response in septic mice. METHODS:Mice were randomly divided into normal control group,model group,miR-146a inhibitor (50 mg/kg)+Dex (50 μg/kg)group,Dex low-dose,medium-dose,high-dose groups(10,30,50 μg/kg),10 in each group. Except for normal con-trol group,other groups were intraperitoneally injected lipopolysaccharide to induce septic models,intraperitoneally injected rele-vant medicines after 0.5 h. After drug intervention for 6 h,miR-146a expression,IRAK1 and TRAF6 mRNA expressions in periph-eral blood mononuclear cells in each group were detected by real-time fluorescence quantitative polymerase chain reaction method. IRAK1,TRAF6 protein expressions in peripheral blood mononuclear cells in each group were detected by Western blot method. TNF-α,IL-6 levels in serum were detected by enzyme-linked immunosorbent method. RESULTS:Compared with normal control group,miR-146a expression,TNF-α and IL-6 levels,IRAK1,TRAF6 mRNA and protein expressions in peripheral blood mononu-clear cells in model group were increased(P<0.01). Compared with model group,miR-146a expression in peripheral blood mono-nuclear cells in Dex medium-dose,high-dose groups were increased;TNF-α and IL-6 levels,IRAK1,TRAF6 protein expressions were decreased (P<0.05 or P<0.01);while IRAK1,TRAF6 mRNA expressions changed less obviously (P>0.05). Compared with Dex high-dose group,miR-146a expression,in peripheral blood mononuclear cells in miR-146a inhibitor+Dex group was de-creased;TNF-α and IL-6 levels,IRAK1,TRAF6 protein expressions were increased (P<0.05 or P<0.01);while IRAK1, TRAF6 mRNA expressions changed less obviously(P>0.05). CONCLUSIONS:Dex can inhibit the inflammatory response in sep-tic mice. The mechanism may associate with inducing miR-146a expression and inhibiting the 2 important adaptor proteins IRAK1, TRAF6 expressions in Toll-like receptor 4/nuclear factor-κB pathway.

Objective: To study the cellular immune responses and the anti-tumor effects induced by peptides derived from onco-protein HER2/neu. Methods: Two HER2/neu peptides compatible with H-2Kd binding motif as tumor rejection antigens were synthesized. The ability of inducing peptide-specific CTLs and suppressing the tumor growth in BALB/c mice immunized by HER2/neu peptide was analyzed. Results: HER2/neu peptides could promote the proliferation of BALB/c lymphocytes both in vitro and in vivo. HER2/neu peptide-specific CTLs could be induced from peptide-immu-nized BALB/c mice, which showed specifically killing effects on HER2/neu positive SP2/OHER2 cells but not on HER2/neu negative SP2/O cells. Moreover, the growth of SP2/OHER2 tumor were significantly suppressed in BALB/c mice immunized with HER2/neu peptides. Conclusion: These results suggested that it was feasible to use MHC-I epitopes derived from tumor-specific antigens as vaccines for cancer immunotherapy.

Objective To investigate the alleviative effects of lidocaine postconditioning on pulmonary injury following ischemia reperfusion. Methods Seventy-two adult SD rats were randomized to 4 groups; sham group, ischemia-reperfusion (I-R) group, ischemic postconditioning(IPC) group and lidocaine postconditioning group. The pulmonary ischemia-reperfusion model was established by occlusion of the left hilum of lung for 45 min and the reperfusion was taken by removing the clamp for 2 h. At the moment of reperfusion, lidocaine 4 mg/kg was injected as a priming dose following a continuous rate of 4 mg/(kg · h). PaO_2, TNF-α, W/D of left lung, the level of MDA of left lung tissue were measured. At the end of reperfusion left lung was removed for microscopy. Results After reperfusion PaO_2 of lidocaine group was much higher than that of I-R group (P<0.05). Lidocaine postconditioning induced a significant decrease in the level of MDA of lung tissue[(7. 03±1.17) μmol/L] compared with ischemia reperfusion group [(8.77±1.42) μmol/L] (P<0.05). Lidocaine postconditioning resulted in a lower level of TNF-α [(1. 69±0.34) μg/L] than that of I-R group [(2. 52±0. 54) μg/L] (P < 0. 05). Microscopic examination showed that lidocaine postconditioning could decrease the level of edema of left lung and accumulation of neutro-phils. Conclusion Lidocaine postconditioning exerts a protective effect on pulmonary ischemia-reperfusion injury administered in the beginning of reperfusion. The effect may be explained by to the antioxidant effect and the suppression of expression of TNF-α.

Aim To study the pharmacokinetics of midazolam tablet after a single oral dose in Hui,Koreanand Han healthy volunteers.Methods Ten Hui, ten Han and nine Korean healthy volunteers were involved in the study. Each subject received a single dose of 15 mg midazolam tablets. The plasma concentration was determined by HPLC. The pharmacokinetic parameters were calculated by DAS2.0 software and compared by one-way analysis of variance or KrusKal-Wallis rank test for PK parameters of different nationalities.Results There were statistically significant differences between Hui,Korean and Han nationality for PK parameters C_(max),MRT_(0～12 h) and T_(max)(P＜0.05).The ranges of interindividual variation in the different ethnic groups and the same ethnic group were large.There were not satisfactory differences between young males and females for all pharmacokinetic parameters(P＞0.05).Followimg oral administration, doublepeaks in midazolam blood concentration-time profiles were observed in more than half of subjects.Conclusion There are large interindividual variation and statistically significant difference in pharmacokinetics of midazolam tablet between Chinese Hui, Korean and Han.These observations suggest the dosage of midazolam should be adjusted in clinical practice.

Objective To explore the correlation between Chlamydia pneumoniae (Cpn) infection and sudden sensorineural hearing loss (SSHL). Methods One hundred and twenty patients with SSHL were enrolled as SSHL group, and another 120 healthy subjects were served as control group. Human peripheral blood mononuclear cells (PBMCs) were isolated, and the expression of Cpn-specific antigen (Cpn-Ag) and Cpn-DNA in PBMCs was detected by direct immunofluorescence test and PCR, respectively. Specific antibodies (IgA, IgG and IgM) to Cpn were determined by microimmunofluorescence test.Results There was no significant difference in the positive findings between direct immunofluorescence test and PCR (P>0.05). There were significant differences in the positive rates of Cpn-Ag and Cpn-IgM for acute infection between these two groups (P＜0.01), and there were significant differences in the positive rates of Cpn-IgA and Cpn-IgG for chronic infection between these two groups (P＜0.05). Conclusion There is a significantly higher prevalence of Cpn in patients with SSHL. Cpn infection may be a possible cause for SSHL.

Objective To investigate the influence of coix seed triglyceride combined with transcatheter arterial chemoembolization (TACE) therapy on AFP, CD4﹢CD25﹢regulatory T (Treg) cells and cellular immune function in patients with advanced primary hepatocellular carcinoma (HCC). Methods A total of 50 patients with inoperable HCC, whose imaging examination showed no distant metastasis, were divided into the study group (n=25) and the control group (n=25). Coix seed triglyceride together with TACE was employed for the patients of the study group, while only TACE was adopted for the patients of the control group. For the patients of the study group, transcatheter hepatic artery infusion of 100 ml coix seed triglyceride was carried out during the performance of TACE, and postoperative intravenous drip of coix seed triglyceride (200 ml/d) was used for 5 days. The peripheral blood samples were collected one week before and one month after the treatment to detect the changes of AFP and T lymphocyte subsets (CD3﹢, CD4﹢, CD8﹢,CD4﹢/CD8﹢ and Treg) levels. One month after the treatment, enhanced CT, MRI or PET-CT was performed to evaluate the necrosis degree of the tumor. Results After the treatment, AFP levels was decreased in both groups, when compared the preoperative data the differences were statistically significant (P<0.01); the tumor necrosis rate of the study group was (57.7 ±8.2)%, which was slightly higher than (57.7±8.2)% of the control group, however, the difference was not statistically significant (P>0.05). In the study group, the percentage of Treg cells decreased from preoperative (8.27±6.65)%to postoperative (4.22± 1.59)%, the difference was statistically significant (P<0.01). The percentages of CD3﹢ and CD4﹢ and the ratio of CD4﹢/CD8﹢ increased from preoperative (55.78 ±13.66)%, (43.98 ±14.00)% and 1.22 ±0.64 to postoperative (62.29±10.78)%(P<0.01),(51.82±16.32)% (P<0.05) and 1.54±0.80 (P<0.05) respectively, while the percentage of CD8﹢decreased from preoperative (45.71±12.94)%to postoperative (39.70±12.41)%(P<0.05). In the control group, no statistically significant differences in the above mentioned indexes existed between preoperative data and postoperative ones (P>0.05). Conclusion In treating advanced primary HCC, coix seed triglyceride combined with TACE can reduce the percentage of Treg cells, thus, influence the patient’s cellular immune status and possibly decrease the recurrence rate of HCC after TACE therapy.
