A deep analysis of the present 26 non-government awards on medical technology achievements was made to probe into setbacks in access to such awards.The findings include lack of independence due to the semi-official nature,tight budget caused by limited funding sources,variety of award sizes due to lack of levels,less corporate involvement to result in less sponsors,and lack of international awards due to unsatisfactory international awareness.The authors recommend such optimal paths as laws and regulations to regulate such awards to be hosted by legal persons,incentives for more enterprises participation to make the awards a public highlight among enterprises,control over the size and types of such awards for better branding,and greater efforts in international collaboration to make international awards.

OBJECTIVE:To compare the contents of 2 index components in salt frying and salt steaming samples of Psoralea corylifolia,and select better processing technology. METHODS:Under the conditions that ratio of salt and medicinal materials was 1:50,4-5 times salt of adding water,brine run time was 2 h,the amounts of psoralen and isopsoralen in salt frying samples after 10,12,14 min of frying under 150 ℃,170 ℃,190 ℃ and in salt steaming samples after 1,1.5,2,2.5 h of steaming were re-spectively investigated,and the effects of 2 processing technology were compared. RESULTS:Under fixed condition,the contents of index components was the highest in salt frying samples by fried for 12 min under 150 ℃ and in salt steaming samples by steamed for 1 h;the content in salt steaming samples (1.49%) was higher than that in salt frying samples (1.29%)(P=0.011). CONCLUSIONS:According to the comparison of index components'contents in processing samples,salt steaming is superior to salt frying of P. corylifolia.

Objective To investigate serum NK cell levels in HBeAg positive early pregnancy women with immune activation.Methods Fifty four HBeAg positive pregnant women admitted in Taizhou People's Hospital from September 2010 to April 2013 were enrolled in the study.Among them,the serum HBV DNA load decreased ≥2 log at 12 weeks after pregnancy in 24 cases (immune activation group) and HBV DNA did not decrease in 30 cases (immune tolerance group).The serum level of alanine aminotransferase (ALT),total bilirubin,HBeAg,HBV DNA load and NK cells were measured.Results At week 12 of gestation,the mean ALT levels and ALT abnormality rate in immune active group were higher than those in immune tolerance group [(146.7 ±93.1) vs.(44.1 ± 14.7) U/L,t =2.95,P<0.05,50.0% vs.6.7%,x2 =4.97,P <0.05].There was no significant difference of HBeAg level between two groups before pregnancy,while HBeAg level in immune activation group was lower than that in immune tolerance group at week 12 week of gestation [(291.8 ± 170.5) vs.(443.7 ± 289.9) S/CO,t =2.81,P <0.05].The percentage and absolute number of NK cells in immune activation group were higher than those in immune tolerance group [(26.7 ±9.1)% vs.(17.1 ±7.8)%,t =2.52,P <0.05 and (370.9 ±136.4)/μl vs.(213.2 ±97.8)/μl,t =2.38,P <0.05,respectively].Conclusions In HBeAg positive early pregnant women with immune activation,the inhibition of HBV DNA might be associated with the activation of NK cells.

Objective To study mechanisms of lipopolysaccharide (LPS) release from Acinetobacter baumannii (A. baumannii) induced by biapenem (BIPM), meropenem (MEM) and levofloxacin (LVFX). Methods A. baumannii was ex-posed to different concentrations of BIPM, MEM, LVFX, and ceftazidime (CAZ) at different time points. The LPS release was measured by tachypleus amebocyte lysate (TAL) test. Quantities of bacteria exposing to 0.5 MIC antibiotics were measured. The morphology of bacteria treated with different antibiotics for 7-hour was evaluated by light microscope. Results The LPS releases of A. baumannii treated with four kinds of antibiotics were significantly less than those of control group. In the later period, LPS releases of A. baumannii exposed to the high concentration of antibiotics tended to smooth. The cell quanti-ties of bacteria were significantly lower in treatment group than that of control group. The cells of A. baumannii treated with CAZ and LVFX showed long filamentous shape. The bacteria exposed to MEM and BIPM showed obviously globular. At the same time, some bacterial cells were induced to lysis rapidly by BIPM. Conclusion The level of LPS release is influenced by kinds of antibiotics, concentration and incubation period. All kinds of antibiotics could induce morphological changes of A. baumannii, which may be related to the different mechanisms that bacteria induce the different levels of LPS release.

Objective To evaluate the relationship between the anesthesia factor and myocardial injury in the patients undergoing cardiac surgery with cardiopulmonary bypass (CPB).Methods Eightyeight patients of both sexes,aged 42-71 yr,weighing 59-83 kg,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ (New York Heart Association Ⅱ or Ⅲ),scheduled for elective coronary artery bypass grafting with CPB,were divided into 4 groups (n =22 each) using a random number table:routine anesthesia control group (group C),dexmedetomidine-based anesthesia group (group D),sevofluranebased anesthesia group (group S) and dexmedetomidine combined with sevoflurane anesthesia group (group DS).After tracheal intubation,0.2%-2.1% sevoflurane was inhaled until the beginning of CPB in S and DS groups.In D and DS groups,dexmedetomidine was intravenously infused as a loading dose of 1 μg/kg over 10 min before induction of anesthesia,followed by an infusion of 0.4 μg · kg-1 · h-1 until the end of surgery.Before induction of anesthesia,before CPB,after the end of CPB,immediately after the end of surgery and at 24 h after surgery,venous blood samples were collected for determination of plasma creatine kinase-MB (CK-MB) and cardiac troponin I (cTnI) concentrations by immunofluorescence.The restoration of spontaneous heart beat and adverse events such as hypotension,malignant arrhythmia,cardiac arrest and respiratory depression during surgery and within 24 h after surgery were recorded.Results Compared with group C,the plasma concentrations of CK-MB and cTnI were significantly decreased in the other three groups (P<0.05).The plasma eoncentrations of CK-MB and eTnl were significantly lower in group DS than in S and D groups (P<0.05).There were no significant differences in the rate of restoration of spontaneous heart beat among the four groups (P> 0.05).No adverse events were found during surgery and within 24 h after surgery in the four groups.Conclusion Dexmedetomidine combined with sevoflurane anesthesia is helpful in reducing myocardial injury and provides better efficacy than either alone in the patients undergoing cardiac surgery with CPB and is more suitable for cardiac surgery with CPB.

Objective To investigate the epidemiological characteristics of Brucella aggregation of disease outbreaks, and explore the causes and possible routes of transmission in Tongxiang City for proposing prevention and control measures.Methods A case investigation was done to the first case of bovine brucellosis, while search of new case was carried out in the population.Epidemiological survey was carried out in accordance with the case study form from Chinese Center for Disease Control and Prevention that developed the unified form, at the same time, survey of risk factors were carried out.According to the principle of informed consent, blood samples were collected, brucellosis rose bengal plate agglutination test (RBPT) and tube agglutination test (SAT) were used, and positive specimens were identified by Brucella culture.Brucellosis diagnosis was based on Brucellosis Diagnostic Criteria (WS 269-2007).Results The first case was a male Fifty-six years old wine salesman from the farmers market.Serum of the patient was (+) in RBPT test, and 1 : 400 (++) in SAT test.Cattle Brucella was check out by blood culture.Totally 66 human serum samples from the case search in key groups were tested, three people were detected seropositive but Brucella culture result was negative.Three cases were determined latent infection who had contacted beef sales staff.Conclusions The survey has shown that it is possible to get infected through contact with respiratory, skin, mucous membranes of Brucella infected beef or contaminated environment.Epidemic form should be concerned of non-professional personnel who are infected with different isoforms of brucellosis.The training of clinicians should be strengthened to improve their diagnosis and treatment technology.Health education should also be carried out to raise awareness of key population of disease prevention.
