Objective To evaluate the effect of meglumine cyclic adenosine (MAC) on heart rate variability (HRV) in aged-patients with coronary heart disease (CHD).MethodsSeventy six aged-patients with CHD were randomly divided into control group (n =36) and treatment group (n =40).The patients in control group were treated with nitrate,ozagrel,calcium antagonist,aspirin enteric-coated tablets,low molecular heparin,angiotensin-converting enzyme inhibitor ( ACEI ) or angiotensin receptor antagonist ( ARB ) and lipidlowering agents according to patients' conditions.Based on this,the patients in treatment group were treated with MAC 90 mg intravenous injection once a day for two weeks.The 24 h dynamic electrocardiogram was recorded.pre-ard post-treatment,and the changes of HRV indexes were observed.Results There was no statistical significance in HRV between the two groups before treatment ( P ＞ 0.05 ).However the HRV in two groups improved significantly after treatment ( P ＜0.01 ).The improvement of HRV was more significant in MAC group than that in control group (P ＜0.01 ).Conclusion MAC can significantly improve HRV in aged-patients with CHD.

“Acupoint characteristics” has a significant influence on the study of acupoints. The description pattern of “property of Chinese medicine - function - indication” of analogy TCM put forward the description pattern of “acupoint characteristics-function-indication axis”. The study was carried out from the following three aspects:sorting, forming and improving the theories on acupoint characteristics; determining the functions according to present theories and indications of acupoints, methodizing the indications of acupoints; through functions, gradually simplifying and supplementing. Therefore, the above would make great sense to further research and systematic study and memorizing of acupoints and promoting clinical thinking about acupuncture, with a purpose to better guide clinical application.

ObjectiveTo evaluate the effect of alpha-lipoic acid (ALA) on cardiomyocyte apoptosis following renal ischemia-reperfusion injury(RIRI) in rats.MethodsThirty-six male SD rats weighing 250-280 g were randomly divided into 3 groups ( n =12 each): group sham operation (group S) ; group I/R and group I/R + ALA ( group L).The model of RIRI was produced by occlusion of renal artery and vein for 45 min followed by 24 h reperfusion,in group S the renal pedicles were exposed but not occluded.In group L ALA infusion (30 mg/kg) was given via tail vein at 20 mln before ischemia and at 20 min before reperfusion,while in group I/R the equal volume of solution (35％ polyethylene glycol + 60％ physiological saline + 5％ ethanol) was infused instead of ALA.The animals were saerificed at the end of 24 h of reperfusion,blood samples were taken for detecting concentrations of serum creatinine (Cr) and malondialdehyde (MDA).Then the hearts were immediately removed for determination of SOD activity,MDA content,cardiomyocyte apoptosis (flow cytometry) and Bcl-2/Bax ratio (immunohistology).ResultsSerum Cr concentration,serum and myocardium MDA levels and cardiomyocyte apoptosis were significantly increased after RIRI in groups I/R and L as compared with group S ( P ＜ 0.05).ALA treatment significantly decreased serum Cr concentration,serum and myocardium MDA levels,cardiomyocyte apoptosis and increased SOD activity and Bcl-2/Bax ratio ( P ＜ 0.05).ConclusionALA can attenuate myocardium injury by inhibiting cardiomyocyte apoptosis following RIRI in rats.

AIM: To investigate the effect of CP466722, an inhibitor of ataxia telangiectasia mutated protein (ATM), on the proliferation and apoptosis of human hepatocellular carcinoma HepG2 cells.METHODS: The cell viability was detected by MTT assay.The cell growth inhibition was measured by colony formation assay.The effect of CP466722 on the cell cycle distribution of the HepG2 cells was examined by flow cytometry.The cell apoptosis was analyzed by TUNEL staining.The protein expression was examined by Western blotting.RESULTS: CP466722 inhibited the cell viability and cell proliferation in a dose-dependent manner.In CP466722-treated HepG2 cells, the cell cycle was arrested in G2/M phase, and the protein levels of phosphorylated cell division cycle protein 2 (p-Cdc2), cell division cycle protein 25C (Cdc25C) and phosphorylated Cdc25C (p-Cdc25C) were inhibited, whereas the protein expression of p27 was up-regulated.CP466722 triggered the apoptosis of HepG2 cells through cleavages of caspase-3 and poly (ADP-ribose) polymerase (PARP).In addition, CP466722 increased the phosphorylation of p38 mitogen-activated protein kinase (p38 MAPK) and suppressed the expression of β-catenin and survivin in the HepG2 cells.CONCLUSION: CP466722 inhibits the proliferation and induces the apoptosis of HepG2 cells, which may be related to activating p38 MAPK and inhibiting the expression of β-catenin and survivin.

Objective To investigate the prevalence, etiology, rehabilitation demands and service condition of hearing disorders based on the whole population in Jilin Province, China. Methods Using the probability proportion to size (PPS) sampling, 9246 (93.3%) out of 9909 residents sampled form 36 counties were targeted for investigation from August, 2014 to January, 2015, followed the WHO Ear and Hearing Disorders Survey Protocol. The hearing loss and disability were classified as WHO recommended and Classification and Grading Criteria of Disability (GB/T 26341-2010). Results The standardized prevalence of hearing loss and disability was 16.41%and 4.78%, re-spectively. Age, sex, residence, occupation and marriage status, education level and household income were significantly associated with hearing loss prevalence, while nationality was not. The main etiologies included non-infectious disease (47.33%), ear disease (14.17%), un-known causation (13.89%), and noise (8.59%). Among all people with hearing loss, those who accepted intervention service accounted for 11.02%. Among all people with hearing disability, those who used hearing aids accounted for 5.58%, and 0.67%used artificial cochlea. Con-clusion Demographics and socioeconomic factors are significantly associated with the prevalence of hearing loss. The main etiology con-tains non-infectious disease, ear disease and noise. Both the rate of service utilization among people with hearing loss and the rate of adopt-ing hearing aids among people with hearing disability are low. It is needed to do more in prevention and rehabilitation of hearing impairment.

BACKGROUNDTo explore the perioperative changes of T subsets and NK cell and analyze the related factors in patients with lung cancer.

METHODSThe T subsets and NK cell from peripheral blood of 60 patients with lung cancer, 15 patients with lung benign tumor and 15 healthy people were detected by immunofluorescence. These indexes of the patients with lung cancer were detected also at postoperative 2nd, 7th, 14th and 28th days.

RESULTS1.There were significant differences in the indexes between the lung cancer group and the groups of lung benign tumor and normal people except for CD8+ (P < 0.05). 2.At postoperative 2nd day CD3+, CD4+, CD4+/CD8+ and NK cell of the patients with lung cancer were decreased and CD8+ was increased significantly than those before operation (P < 0.05). During postoperative 1 to 2 weeks, all indexes had recovered basically to the preoperative level. At postoperative 28th day, CD3+, CD4+ , CD4+/CD8+ and NK cell were increased and CD8+ was decreased than those before operation (P < 0.05). 3. There was significant difference in the indexes among preoperative stage IIIA, IIIB and IB, and between preoperative N2 diseases and N0 group (P < 0.05). There was significant difference between the groups of radical and palliative operation and the group of thoracic exploration at postoperative 28th day (P < 0.05). There was significant difference in T subsets between the groups of blood transfusion and non-transfusion at postoperative 14th day (P < 0.05).

CONCLUSIONSThe cellular immune function of the patients with lung cancer was lower than that of the patients with lung benign tumor and normal people. The perioperative immunity of patients with lung cancer decreases after operation and increases later. TNM stage and lymph node metastasis are relative to preoperative but not postoperative immunity. There is no significant correlation between cellular immune function and pathological type of the tumor. Radical and palliative operations can both significantly increase the patients' cellular immune function. Therefore the palliative operation is better than thoracic exploration. Blood transfusion can depress the immune function of the patients, so it is better to avoid perioperative blood transfusion.

OBJECTIVE：To study the skin irritation and se nsitization of domestic generic drug Clobetasone butyrate cream ， and to compare it with commercial drug （original drugs ）. METHODS ：The skin irritation test was conducted on rabbits. Totally 24 rabbits were randomly divided into test preparation intact skin group ，test preparation abraded skin group ，commercial drug intact skin group and commercial drug abraded skin group ，with 6 rabbits in each group. 0.5 mL test preparation or commercial drug was administered to the left side of intact or abraded skin and the same amount of excipient on the right side of each rabbit twice a day for consecutive 7 days. The irritation of the drug to the rabbit skin was observed ，and the erythema and edema of the skin were scored；the skin of administration site was taken at 72 h after last administration and the end of 7 d after drug withdrawal for histopathological examination. The skin sensitization test （Buehler test ）was carried out on guinea pigs. Totally 60 guinea pigs were randomly divided into test preparation group （n＝20），commercial drug group （n＝20），positive control group （n＝10）and excipient control group （n＝10）. 0.2 mL test preparation or commercial drug was administrated to the left side of the rib abdomen skin of each guinea pig at the 0，7th，14th day to induce model ，and an equal amount of corresponding preparation was administered to the right side in the same way at the 28th day for stimulation. Hypersensitive response such as erythema and edema were observed and scored at 24 h and 48 h after the stimulation. The incidence of hypersensitive response was then calculated. RESULTS：In skin irritation test of rabbits ，no erythema and edema was caused by the test preparation or commercial drug on intact skin of rabbits ；scores of skin irritation was 0；there was no dermal irritation. Both test preparation and commercial drug caused transient slight erythema on abraded skin of a few rabbits ；scores of intact and abraded skin irritation were 0-0.33；there was no dermal irritation. There was no statistical significance among groups. No dermal pathological changes were observed. In skin sensitization test of guinea pig ，no hypersensitive response such as erythema and edema was found on the skin of guinea pigs in both test preparation and commercial drug groups ；both score and the incidence of hypersensitive response were 0. Compared with excipient control group ，there was no statistical significance of average score and the incidence of hypersensitive response in test preparation group and commercial drug group. CONCLU- SIONS：In skin irritation test of rabbits and skin sensitization test of guinea pigs ， the evaluation results of generic Clobetasone butyrate cream are the same as those of the original drug. It has no irritation to the skin of rabbit ，and no sensitization to the skin of guinea pigs.
