Objective To construct recombinant prokaryotic plasmid DNA encoding mycobacterium tuberculosis (TB) heat shock protein 70 (HSP70) - Dnak gene obtained from pMT70, then purify its characterizes and the role of rHSP70 in tumor therapy. Methods Amplified by polymerase chain reaction (PCR) and with terminal modification, the Dnak gene was cloned into the vector with T7 promoter and was confirmed by restriction endonuclease digestion. So a new plasmid pMT70 - 3 was constructed and transformed in E. Coli. Strain BL21DE3. The engineering bacteria were induced by IPTG. Western-blot,natine-page and scanning were used to analyze the results. The human HSP70 were induced with peptides of lymphocytic leukemia cells of L1210 of mice in binding buffer which contain MgCl2 and ADP at 37 ℃ , then mice were given rHSP70 peptide - complex by SV injection twice at weekly intervals. Results The Dnak gene could be highly expressed in E. Coli as soluble protein. The expressing efficiency was 65% of the total cell protein and the soluble protein was 90% of the expressed protein. The rHSP70 - peptide complex could improve the immune protective function which had significant difference compared with controls (P

Objective To observe the curative effect of captopril and metoprolol in the treatment of chronic Keshan disease (CKD). Methods One hundred and ninty-five patients with CKD chosen from Juxian, Wulian, Yishui, Pingyi, Sishui and Zoucheng in Shandong Province were randomly assigned to control group, captopril group and metoprolol group according to NYHA cardiac functional grading. All cases were given diuretics, digitalis and vasodilating agents as routine treatment. On this basis, captopril and metoprolol was administered in captopril group and metoprolol group respectively. After 12 months of follow-up visit, the causes of cardiac death, hospitalization status and the changes of heart size, electrocardiogram, blood pressure and heart rate were all observed. Results It was found that the mortality of captopril group and metoprolo] group was 4.76% (3/63), 5.00% (3/60) respectively, both lower than the control group 10.61%(7/66). But this difference had no statistically significance(P=0.39). Besides, the hospitalization days of each year in captopril group and metoprolol group was respectively (19.12± 20.35) and(18.86±21.52)days, much more reduced than in the control group[(21.45±21.74)days, q=3.17, 3.38, P<0.05]. The detection rate of cardiothoracic ratio decreased in captopril group and metoprolol group [45% (27/60) and 40.4% (23/57)] After treatment showed more pronounced amelioration than the control group [18.6% (11/59), χ2=9.51,6.59, all P<0.0125], still the detection rate of cardiomegaly and invariability had no significant difference among three groups (χ2=2.50,4.75, all P>0.05). The elimination coefficient of ectopic rhythm in metoprolol group [56.5% (13/23)] was pronounced higher than the control group and captopril group [23.8% (5/21), 22.7% (5/22)], but differences had no statistically significance(P=0.0358,0.0331, all P>0.0125). Significant differences were found in systolic blood pressure(SBP), diastolic blood pressure(DBP) and heart rate(HR) in three groups prior and post-treatment(F=47.51,44.23,80.66, all P<0.01). The interaction of therapy and treatment time had influence on SBP and HR (F=3.19,37.44, all P<0.05), but had no influence on DBP(F=2.21, P> 0.05). There was no difference in SBP, DBP or HR among three groups before treatment(F=0.28,0.57,1.80, all P>0.05). After treatment, SBP and DBP in captopril group, metoprolol group and the control group[(109.0±10.9), (112.2±12.8), (114.7±13.2)mm Hg, (69.3±7.2), (72.1±9.5), (73.3±9.3)mm Hg] were all lowered compared with pre-treatment[ (117.1±13.4), (119.0±14.4), (117.6±14.1)mm Hg and (74.2±10.2), (76.3±10.8), (75.4±11.1)mm Hg, t=4.79,4.47,2.08,5.12, 4.32,2.15, all P<0.05]. HR was reduced in metoprolol group, being [(66.2±7.7), (75.9±11.5)times/min] before and after treatment(t=10.81, P<0.01), while it remained unchanged in captopril group and control group[(70.6±8.0), (72.6±10.5) times/min and (71.9±10.4), (73.8± 12.2)times/min, t=1.77,1.74, all P>0.05]. After treatment, both SBP and DBP of captopril group were significantly lower than that in the control group (q=3.52,3.56, all P<0.05); HR was reduced in metoprolol group, lower than that in captopril group and control group(q=5.44,3.73, all P<0.01). Conclusions Having a tendency of depressing mortality, captopril and metoprolol can reverse or delay myocardial remodeling and reduce admission rate in a safe,reliable and economic way, and are worth to be widely used in the treatment of chronic Keshan disease.

OBJECTIVETo compare the efficacy on vertebrobasilar insufficiency (VBI) between auricular acupuncture therapy and oral administration of medicine.

METHODSSixty patients of VBI were randomized into an auricular acupuncture therapy group and a medicine group, 30 cases in each one. In the auricular acupuncture group, acupuncture was applied bilaterally to gan (CO12) and jiejie (HX8) on the ears and needles were retained for 15 min. After needle withdrawal, the vaccariae semen were fixed with plaster at naogan (AT3, 4i), zhen (AT3), jing (AH12), shen (CO10) and pi (CO13) on the ears. In the medicine group, flunarizine hydrochloride capsules (Sibelium), 5mg were prescribed for oral administration, once every night. The treatment lasted continuously for 2 weeks (14 days) in the two groups. In 2 weeks, the clinical efficacy was assessed and the transcranial doppler (TCD) examination was performed.

RESULTSAfter treatment, the symptom scores were all apparently reduced in the patients of the two groups (P < 0.01, P < 0.05). Compared with the medicine group, the reduced score was much more obvious in the auricular acupuncture group (P < 0.05), indicating the significant difference. After treatment, with TCD examination, the blood velocity was increased to different degrees in the patients of low velocity type in the auricular acupuncture group and the medicine group; that was reduced to different degrees in the patients of high velocity type in the auricular acupuncture group and the medicine group. All of them were different significantly as compared with those before treatment (all P < 0.05). But the difference was not significant between the two groups (both P > 0.05). In comparison of clinical efficacy between the two groups, the effective rate was 93.3% (28/30) in the acupuncture group and better than 76.7% (23/30) in the medicine group, indicating the significant difference in comparison (P < 0.05).

CONCLUSIONThe auricular acupuncture therapy achieves the definite efficacy on VBI and the efficacy is better than flunarizine hydrochloride capsules.
