Objective To investigate the regulation and the mechanism of Melatonin in calcium overload of pancreatic acinar cell in acute necrotizing pancreatitis (ANP). Methods Fifty-four Sprague-Dawley (SD) rats were equally divided into three groups:sham-operation group (SO group),ANP group (created with retrograde cholangiopancreatography injection of sodium taurocholate) and MT group (ANP model made after intra-peritoneal injection MT for 30 mins).Rats were sacrificed at 1,4 and 8hours after operation and pancreas tissues were underwent pathological examination.The free calcium concentration of pancreas tissues was determined by fluorescence minitoring method; and the expression of CaMK Ⅱ in pancreas tissues at mRNA and protein level was tested by real-time PCR and Western Blot.Results Pancreatic pathological injury in ANP groups was progressively severe as time extended,which was obviously ameliorated in MT group compared with ANP group (the t value of compared pathological score at 1,4 and 8 hour was:-7.95,-9.72 and -7.69,all P=0.00).Compared at same time point,the free Ca2+ concentration of pancreas tissues in ANP group was significantly higher than that of SO group (the t value of 1,4 and 8 hour was 13.09,18.58 and 16.56,all P=0.00).It was a little bit higher in MT group compared with that of SO group,however was significantly lower than that of ANP group (the t value of 1,4 and 8 hour was -10.03,-11.75 and -11.02,all P =0.00).Compared with SO group,the expression of CaMK Ⅱ at mRNA and protein level significantly increased in ANP group; MT significantly inhibited its expression.Conclusions The expression of CaMK Ⅱ may be inhibited by MT interfere,and then lower the calcium overload in pancreatic acinar cell,which play a role in pancreas tissue protection.

OBJECTIVETo explore the clinical efficacy of moxibustion on rheumatoid arthritis (RA) in the patients and the impacts on the inflammatory indices.

METHODSForty RA patients were randomized into an observation group and a control group, 20 cases in each one. In the control group, diclofenac sodium sustained release tablets were used, 0.3 g each time, twice a day; methotrexate tablets were used, 10 mg each time, once a week; folic acid was used, 5 mg each time, once a week. In the observation group, on the basis of the treatment as the control group, moxibustion was added specially on the swelling and painful joints, once a day, 15-20 min each time till: the local skin turned slightly red. The treatment was given once a day, at the interval of 1 day after every 6 treatments. In the two groups, the efficacy was observed after 30-day treatment. Before and after treatment, the rheumatoid factor (RF), high sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), disease activity score-28 (DAS-28) and the score of joint symptom and physical signs were observed.

RESULTSCompared with those before treatment, the levels of RF, hs-CRP, ESR, DAS-28 and the symptom scale score were all reduced in the RA patients of the two groups after treatment (all P < 0.05). Compared with the control group, the levels of RF, hs-CRP, ESR, DAS-28 and the symptom scale score in the observation group were improved much apparently (all P < 0.05). The total effective rate was 85.0% (17/20) in the observation group and was 80.0% (16/20) in the control group. The total effective rate in the observation group was apparently better than that in the control group (P < 0.05).

CONCLUSIONMoxibustion as supplement relieves the joint symptoms, reduces the inflammatory reactive indices and improves the clinical efficacy in the RA patients.

Objective: To evaluate the impact of intracoronary administration of eptifibatide oncoronary no-reflow and myocardium perfusion in patients with ST-elevation myocardial infarction (STEMI) at percutaneous coronary intervention (PCI). Methods: A total of 80 STEMI patients with emergent PCI were randomly divided into 2 groups: Eptifibatide group, the patients received intracoronary administration of eptiifbatide and Control group, the patients received the same volume of normal saline.n=40 in each group. The baseline condition, post-operative vascular recanalization, changes of platelet aggression at pre- and post-medication were compared between 2 groups. Echocardiography was examined at immediately and 24 weeks after operation;myocardial infusion imaging was examined at l week after operation. All patients were followed-up for 24 weeks to observe the incidence of major adverse cardiovascular events (MACE). Results: Compared with Control group, Eptifibatide group showed increased ratios of post-operative TIMI grade 3 (72.5%vs 92.5%) and myocardium perfusion (70.0% vs 90.0%), bothP<0.05; decreased post-operative and 2h post-medicinal platelet aggression and they were both lower than Control group at the same period, allP<0.05. Eptiifbatide group had obviously improved LVEDD and LVEF at 24-week than 1-week after PCI and they were both superior to Control group, allP<0.05. There were 7 (17.5%) patients in Eptiifbatide group and 7 (7.5%) in Control group suffering from small bleeding events, P>0.05; no severe bleeding eventand no in-hospital thrombocytopeniaoccurred. MACE occurrence rates during 24-week follow-up period were 12.5% vs 22.5%, P>0.05. Conclusion: Intracoronary administration of eptiifbatide in STEMI patients at emergent PCI could effectively improve coronary blood lfow,increase myocardium perfusion and enhance cardiac function without severe bleeding events.

OBJECTIVE: To find out some evidence that may indicate the theory of voice pitch of the five tones being correlated with the five zang viscera in Huangdi Neijing, which was lost 2 000 years. METHODS: Eight-four healthy females were divided into younger group (<34 years old) and older group (> or =34 years old) according to their ages. The pronunciations of these females were examined by sono-frequency analysis facility. RESULTS: The frequency of Jiao tone was much higher than those of the other tones in both groups (P<0.01) and the frequency of Jiao tone increased as aging. The frequency of Zhi tone in the younger group was higher than that in the older group (P<0.05). CONCLUSION: The results of higher frequency of Jiao tone in females is in accordance with the theory put forward by Ye Gui (a famous doctor in Qing Dynasty of China) that the liver is the congenital base of female life. In traditional Chinese medicine, Jiao tone is correlated with the liver, and Zhi tone is correlated with the heart. The high frequency of Zhi tone in younger females implies that regulating the Small Intestine Meridian of Hand-Taiyang and Heart Meridian of Hand-Shaoyin may be beneficial to the health maintenance of younger female.
