Objective: To observe the therapeutic effects of RFA combined with chemotherapy drug on hepatic VX: carcinoma in rabbits and to explore its mechanism.Methods: 40 rabbit models with VX: carcinoma were used for this study.they were divided into four groups at random.We watched the changes in serolog ALT,diameter of tumor and pathomorphology.And we also utilized terminal deoxynucleotidyl ransferase-mediated dUTP nick-end-labeling and immunohistochemistry to observe the apoptosis and proliferation.Results: ⑴The blood ALT significantly increased at the first day after treatment,then descended at the third day,and at the seventh day it descended to the level of pretreatment stage in group RFA combined with epirubicin.(2) The diameter of tumor showed significant difference between combined treatment and other groups.(3) Two weeks after treatment,the complete necrotic area slightly extended.it was clearly seen that the zone consisted of normal liver constitution,inflammation hyperemia zone and amorphous necrotic constitution by HE staining in combined treatment group.(4) The apoptosis index of the combined treatment group was bigger than that in other groups by TUNEL technology,but the PCNA index in the combined treatment group was lower than other groups.They all had significant difference.There was negative correlation between apoptosis index and PCNA index in the combined treatment group(r=-0.745,P

A portable instrument for arteriosclerosis assessment containing sensor module, acquisition board and embedded module was developed for home care in this paper. The sensor module consists of one ECG module and three pulse wave extraction modules, synchronously acquiring human ECG and pulse wave signal of carotid, radial, and dorsal, respectively. The acquisition board converts the sensor module's analog output signals into digital signals and transmits them to the embedded module. The embedded module realizes the functions including signal display, storage and the calculation and output of pulse wave velocity. The structure of the proposed portable instrument is simple, easy to use, and easy to expand. Small size, low cost, and low power consumption are also the advantages of this device. Experimental results demonstrated that the proposed portable instrument for arteriosclerosis assessment has high accuracy, good repeatability and can assess the degree of atherosclerosis appropriately.

Objective To investigate the antioxidation of bioactive proteins from the meat of Meretrix meretrix.Methods Three protein peaks(P1,P2 and P3) were isolated from the meat of Meretrix meretrix by homogenating,step precipitating with ammonium sulfate,chromatography with Sephadex G-150.CAT activity and SOD activity of these proteins were determined.Inhibition of the proteins to lipid peroxidation was determined.Results CAT activity of P2 was the highest,its specific activity was 77.0 U?mg-1.SOD activity of P3 was the highest,its specific activity was 68.8 U?mg-1.Inhibition of P3to lipid peroxidation was the most obvious,its inhibitive rate was 50% when the protein content was 20 ?g.SDS-PAGE results showed that the main composition of P1 was the protein,the Mr of which was 18.0 kD.The protein band of P2 corresponded with the protein band of contrast CAT,its Mr was 28.0 kD.The protein band of P3 corresponded with the protein band of contrast SOD,its relative Mr was 16.0 kD.Conclusion The bioactive proteins were isolated from the meat of Meretrix meretrix,and the bioactive proteins had antioxidation.

Chemotherapeutic drugs conventionally used for their cytotoxic activity can also exert their influence on the immune system by grooming the tumor microenvironment,abrogating immune tolerance and inciting immune reconstitution.Due to their immunomodulatory features,chemotherapeutics,used as a preconditioning regimen and combined with subsequent immunotherapy,can mobilize the immune system to generate antitumor immune response.The synergy between chemotherapy and immunotherapy has brought some enlightenment to the development of new protocols for cancer treatment.

The main goal for the foundation of national life science and technology talents cultivating base(biopharmaceutical base) is building up perfect talents education systems to create elites with originality and carving-out ability.4 aspects including optimizing courses?improving teaching technics?enhancing practicing ability and reforming pattern of running school were mentioned to explore the cultivating system of biopharmaceutical base.

Objective To observe the application of alkaline cleaning agent in disinfection and supply room cleaning of medical devices, to evaluate the cleaning quality. Methods The 800 contaminated medical instruments collected from February 2016 to February 2017 in municipal maternal and child health hospital were divided into control group (February 2016 to August 2016) and study group (September 2016 to March 2017 ) according to different time periods,with 400 pieces in each group.In the reference group, the instrument was washed with multienzyme detergent, and the study group was cleaned with alkaline detergent. The cleaning of 2 groups of instruments was observed and compared. Results The total excellent and good rate of instrument cleaning in the study group was 97.25％ (389/400), in the reference group was 89.50％(358/400), the difference between the two groups was statistically significant (P<0.05); the cleaning safety, practicality, economy, comprehensive score difference of the study group was significantly better than the reference group (P<0.05). Conclusion The effect of alkaline cleaning agent used in disinfection supply room cleaning medical instruments is remarkable, and the equipment residue and microorganism can be effectively eliminated, and the utility model has the advantages of high safety and low economic cost, and has the important practical value.

Objective To explore the clinical effect of chlorpromazine(TMZ)in treatment of chronic heart failure(CHF).Methods 70 patients with CHF were randomly divided into control group and treatment group 35 cases in each gronp,control group was given conventional treatment,treatment group on the basis of additional application TMZ,20mg/times,3 times/d.8 weeks after the observation and comparison of two groups of cardiac function in improving the situation.Results Treatment group before the treatment of LVEF(38.0 ± 2.4)％ After treatment,LVEF(48.0 ±2.3)％ ;control group before treatment LVEF(38.2 ±2.2)％ after treatment,LVEF(42.0 t2.5)％ ;Twosets of treatment LVEFdifference statistically significant(t =6.9419,2.8482,allP ＜ 0.05); Treatment group compared with control groups after treatment improve even more obvious(t =4.3147,P ＜0.05)o Control groups and then hospitalized 10 cases(28.5％),the treatment group hospitalization 3 cases(8.5％),both groups rate difference statistically significant(x2 =4.629,P ＜0.05).Both groups were no deaths,no serious adverse effects.Conclusion General against heart failure therapy on the basis of the combined with TMZ could significantly improve the cardiac function of patients with chronic heart failure,reducing hospitalization rates.
