According to topographic anatomy, pathogenesis and by retrieving, summarizing and analyzing literature regarding needle-knife and needles with knife-edge for carotid cardiac syndrome, it is found out that clinical misdiagnosis rate of carotid cardiac syndrome is considerably high. Needle-knife and needles with knife-edge could significantly improve the clinical symptoms of carotid cardiac syndrome, showing characteristic and advantage in treatment, but it is deficient in technique standard and efficacy criteria that should be united and authoritative. Researches regarding pathogenesis of carotid cardiac syndrome are not systematic. Clinical observation regarding long-term efficacy and relapse of needle-knife and needles with knife-edge treatment is rare. It is believed that the awareness on carotid cardiac syndrome should be increased to reduce misdiagnosis; scientific and standardized technique standard and efficacy criteria should be established; systematic and comprehensive researches regarding mechanism of needle-knife and needles with knife-edge for carotid cardiac syndrome should be launched; besides, clinical discussion regarding its long-term efficacy should start to provide a better clinical guideline.

Objective To study the effectrve approach of the nutrition support in burn patients. Methods The means of immuno-precipitation-deduction,ELISA and fluore-photometion were used to test the change of activities,protein expression of the 19S regulator and the rate of protein degradation in skeletal muscle in scard rats with enteral feeding or parenteral nutrition. Results Compared with parenteral nutrition , enteral feeding could markedly reduce the activity and protein expression of the 19S regulator ,and the digeneration of skeletal muscle was also lower. Conclusions The early enteral feeding can distinctly inhibit the system of 26S proteasome , thereby reduce the protein degradation of skeletal muscle in scald rats,which may be benefical to the metabolic modulation of the burned patients.

Objective To explore the mechanism of negative nitrogen balance in the treatment after burns. Methods The means of immuno precipitation deduction and ELISA were used to test the activities and contents of 26S proteasome and 19S regulator in skeletal muscle of rats inflicted with 30%TBSAⅢ burns. Results TNF? markedly raised the activities and contents of 26S proteasome and 19S regulator in skeletal muscle after scalding. Conclusion TNF? activates the 26S proteasome system in skeletal muscle, thus it enhances the degradation of protein, which is associated with the development of negative nitrogen balance following scalding.

Objective To investigate the efficacy and safety of domestic Oseltamivir granules in the treatment of influenza A in children.Methods The research subjects were the hospitalized patients with influenza A coming from the Department of Infectious Disease in Guangzhou Women and Children's Medical Center.from January and March,2014 They were divided into 2 groups randomly.Patients in the treatment group received domestic Oseltamivir granules,while the patients in the control group received foreign Oseltamivir.Chi square test was performed to compare baseline characteristics and the difference in side effects.Paired t test was used to compare baseline characteristics and the difference in side effects.Results There were 44 cases in the study group,27 cases were male(61.36％),17 cases were female (38.64％),and the average age was (2.40 ± 1.97) years old.There were 40 cases in the control group,28 cases were male (70.00％),12 cases were female (30.00％),and the average age was (2.99-± 3.19) years old.The maximum age was 6 years old.The age and gender were not significant (P ＞ 0.05) between 2 groups.The fever remission time was (14.67-± 9.37) h and (11.80-± 9.98) h in the treatment group and the control group,and there was no significant difference between 2 groups (P ＞ 0.05);the flu symptoms completely remission time was (62.50 ± 25.03) h and (65.40 ± 36.74) h in the treatment group and the control group,and there was no significant difference between 2 groups (P ＞ 0.05);the adverse reaction was not observed in the treatment group,but 1 case in the control group had cough,and without special treatment cough alleviated gradually;the close contacts in 2 groups did not develop influenza A.Conclusions The domestic Oseltamivir granules are as effective and safe as the foreign Oseltamivir.And the domestic Oseltamivir granules are the granular type,and therefore more suitable for children

Objective To identify the features of the NCAM+ c-Kit+ subset of hepatic progenitor cells in the intrahepatic cholangiocarcinoma (ICC) cell line RBE.Method Magnetic activated cell sorting was used to isolate NCAM+ c-Kit+/NCAM-c-Kit-subset cells,which were tested for hepatic progenitor cell properties and proliferation,colony formation,and invasive abilities in nude mice.Resuits The cell proliferation ability of NCAM+c-Kit+ subset cells was stronger than that of NCAMc-Kit-subset cells (P＜0.01).In serum-free condition,the number of colonies formed by NCAM+c-Kit+ subset cells was more than that of NCAM-c-Kit-cells (P＜0.01).1 × 104 NCAM+c-Kit+ cells were enough to form tumors in nude mice after subcutaneous inoculation for two weeks,while 1 × 106 NCAM-c-Kit-cells were necessary to form tumors for three weeks.The tumor formation rate of NCAM+c-Kit+ cells was higher than that of NCAM-c-Kit-cells (P=0.04).Conclusions It is possible that NCAM+c-Kit+ subset cells in RBE have the properties of hepatic progenitor cells,and NCAM combined with c-Kit might be a valuable marker for isolating and purifying ICC stem/progenitor cells.

Object To demonstrate the naked truth of four therapeutic features of TCM (cold, hot, warm and cool) from biophysical and biochemical point of view. Methods Growth thermogenesis curves of Escherichia coli were determined under different conditions by microcalorimetry to give biothermodynamic parameters, such as multiplication constant (k), median inhibitory concentration (IC 50 ), and enthalpy (?H). Differences between folia ginseng and flos ginseng were comprehensively compared with reference to classical Chinese literatures on material medica. Results The bacteriostatic curve of both drugs were basically similar. With increasing concentration of decoctions of both drugs, the lag phase was delayed and the peaks shifted to the right. While the difference of ?H was stable, which decreases with the increasing concentration of Folium ginseng, but increases with increasing concentration of Flos ginseng. Conclusion Microcalorimetry is not only a new effective method to describe the therapeutic features of TCM, but also could be used as a tool for the screening of active TCM.

Objective To investigate the circadian and seasonal distribution of cardiovascular events (CVE) and the relationship between average monthly temperature and the incidence of CVE. Methods A total of 5837 emergency patients with CVE were enrolled from 1997 to 2007. The exact admission time of each patient was registered. The average monthly temperature data from a regional weather station for this time period was supplied by the meteorological office of the city. The relationship between the average monthly temperature and the incidence of CVE was explored and the corresponding curves were plotted. Results The occurrence of CVE has obvious seasonal variation, and its a higher tendency of episodes was found in spring and winter periods. High incidence of acute myocardial infarction, angina pectoris, acute left-sided heart failure, hypertensive crisis, and sudden death occurred in spring and winter as wee as the time for a change of season, that is, January, February, March, April, October, November, and December. There was a significant negative correlation between the incidence and the average monthly temperature (P<0.005-0.001). Circadian rhythm of CVE was present, with a peak in the early morning and forenoon. Conclusion There are circadian and circannian rhythms of the incidence of CVE. Cold weather condition is a risk factor for the occurrence of CVE, which usually peaks in the early morning and forenoon.
