OBJECTIVETo observe the immediate effect and the long-term effect on blood pressure (BP) in acupuncture for hypertension.

METHODSSeventy cases of primary hypertension were acupunctured at Renying (ST 9), Hegu (LI 4), Taichong (LR 3), Quchi (LI 11) and Zusanli (ST 36) at 2:00-4:00 pm. BP was recorded before treatment and 5 min, 15 min and 30 min after acupuncture separately every day. The treatment was given for 5 days each week and stopped for 2 days. Totally, 3-month treatment was required. BP was compared at each time point with that before treatment separately on the same day, and made the comparison of it before the treatment every 15 days with that before acupuncture on the 1st day.

RESULTSOn the same day, the systolic pressure at each time point after acupuncture was decreased as compared with that before acupuncture, indicating the statistically significant difference (all P < 0.05). The diastolic pressures at each time point on the 1st, 15th, 30th and 60th days of acupuncture were decreased as compared with that before acupuncture, indicating the statistically significant difference (all P < 0.05). In the 3-month treatment, the systolic pressure and diastolic pressure before treatment every 15 days were decreased as compared with that before the treatment on the 1st day (all P < 0.05).

CONCLUSIONAcupuncture can decrease the immediate BP and maintain the anti-hypertensive effect for primary hypertension so as to achieve the long-term stable anti-hypertensive effect.

Objective To compare the treatment effects of gastric bypass (GBP) and biliopancrtic diversion (BPD) in non-insulin dependent diabetes mellitus rats,and investigate the mechanism.Methods Forty GK rats with diabetes mellitus were randomly allocated into four groups:GBP group; BPD group; food restriction group ( FR group) and control group with 10 rats in each group.Rats in GBP group and BPD group received GBP and BPD procedures respectively.Rats in FR group were fed with basic feed of 15 g and free access to water.There was no food restriction in rats in control group.The operation time,mortality was recorded.The fasting body weight was measured every week.The plasma glucose,insulin-like growth factor-1 (IGF-1),and leptin concentrations,were measured before treatment and 1,2,3,4,8,16 week after treatment.Results The mean operation time was (25 ± 4) min in GBP group and (35 ± 6) min in BPD group; one rat died in GBP group and 3 rats died in BPD group,and the difference between the two groups was statistically significant (P ＜ 0.01 ).The levels of plasma glucose,IGF-1 and leptin were not statistically significant among these groups before treatment.There was no significant difference in plasma glucose and leptin concentrations in the control group.The levels of plasma glucose and leptin in rats in FR group began to decrease 2 weeks later,at the 4th week,the levels of plasma glucose and leptin was significantly lower than that before treatment,and it lasted for the 16 th week,but the level of IGF-1 were significantly different.The levels of plasma glucose and leptin in rats in GBP group and BPD group began to decrease and IGF-1 began to increase 2 weeks after operation,and it lasted for the 16th week,[plasma glucose:(6.8 ± 1.0),(6.3 ± 0.8 ) mmol/L vs.(13.9±2.6),(14.1 ±2.6)mmol/L; leptin:(16.1±3.3),(17.2±3.2)pg/ml vs.(29.4±3.9)pg/ml,(29.4±3.9); IGF-1:(166.1±8.3),(142.2±8.2)ng/L vs.(119.4±8.8),(109.8±7.9)ng/L,P＜0.01],but the levels of plasma glucose and leptin was not statistically different between the two groups.The level of IGF-1 in GBP group was significantly higher than that in BPD group (P ＜ 0.05).Conclusions Both GBP and BPD can effectively control plasma glucose concentration for rats with diabetes.The possible mechanism is related to decreased leptin and increased IGF-1.Group GBP had a better outcome in operation time,mortality and increasing IGF-1 than those in group BPD.

ObjectiveTo study the effect of adaptive group psychological training on mental quality and emotion of soldiers.MethodsA total of 48 soldiers ( experiment group) received group psychological training and read a textbook,Mental Quality Training for soldiers,for 3 months,and the other 45 soldiers served as control group.Armyman mental quality inventory (AMQI),self-rating depression scale (SDS) and state-trait anxiety inventory(STAI) were employed to evaluate the mental quality and emotion of soldiers before and after training.All data were analyzed by paired-sample t test.Results ①As compared with pre-training,the AMQI scores of training group increased significantly in bravery ( 71.50 ± 9.59 ),self-confidence ( 68.24 ± 8.36 ),aptitude ( 74.54 ± 10.81 ),loyalty(75.29 ± 8.08 ) and general score ( 359.07 ± 20.30 ) (P ＜ 0.05,P ＜ 0.01 ) ; and no significant difference were found in those of control group(P ＞ 0.05 ).②When compared with pre-training,the scores of SDS (39.00 ±8.38),SAI(40.14 ±9.92),TAI(41.16 ±7.47) and STAI(81.30 ± 12.52) of training group decreased significantly (P ＜ 0.05,P＜ 0.01 ) ; and no significant difference was found in those of control group(P ＞0.05 ).ConclusionGroup psychological training can improve mental quality of soldiers,which is helpful to relax anxiety and depression of soldiers.

Objective To clarify clinical and morphological features and immunophenotype and Epstain-Barr virus infection of neoplastic cell rich Hodgkin's lymphoma (NCRHL)and to further improve our knowledge and pathological diagnosis for NCRHL. Methods 10 cases of NCRHL were analyzed for clinical features, morphology, immunophenotype, Epstein-Barr virus infection using routine eosin and haematoxylin stain, immunohistochemistry, Epstain-Barr virus encoded small RNA (EBER) in situ hybridization and combining clinical data. Results (1)NCRHL were more common in young people. The median age of the patients was 25.5 years old. The ratio of male to female was 1:2.3. Superficial lymph nodes were most frequently involved. Masses of mediastinum were seen commonly. Clinical manifestation of the patients included B symptom (6 cases), pruitus (5 cases) and anemia (1 case). (2)Architecture of lymph nodes were effected. Necrosis was seen in some cases. There were more tumor cells in NCRHL than that in the classical Hodgkin's lymphoma. The tumor cells were distributed in piece or patch or diffuse. The morphology of neoplastic cells was wore variable including Hodgkin-like cells, lacunar cell-like, mummy cell-like and anaplastic large cell-like, singular nucleated cells, and multinucleated giant cell-like cells. Numerous neutrophils and eosinophils were present in a few cases. Focal sheet, necrosis granulomatosis-like and diffuse growth pattern were found in NCRHL. (3)All of the cases were positive for CD30 and PAX-5.2/10 (20%) cases were CD15 positive. LCA, CD20 and CD3 were negative. (4)EBER was not detected in all 6 tested cases. (5)Follow up data was obtained in 8/10 cases, in which one patient was dead, one case relapsed in half a year,and the other 6 cases reached complete regression. Conclusion NRCHL is characterized mainly by neoplastic cell rich morphologically and focal sheet, necrosis granulomatosis-like and diffuse growth pattern.EBER was not detected in this tumor. Some cases have aggressive clinic process with a unfavourable prognosis. New treatment regimen should be explored.

Objective:To assess whether Veronicastrum axillare (V. axillare) can ameliorate ethanol-induced gastric mucosal lesions in rats, reduce the production of pro-inflammatory cytokines, suppress apoptosis and improve local microcirculation disturbances.
Methods:Totally 48 male Sprague-Dawley rats were randomly divided into six groups, eight rats in each group. Rats in the normal group and the model group were administered with 0.9%normal saline respectively. Rats in the positive group and ranitidine group were administered with 0.18% ranitidine suspension by intragastric administration respectively. Those in the high dose V. axillare group, the medium dose V. axillare group and the low dose V. axillare group were administrated with V. axillare at the daily dose of 2.8 g/kg, 1.4 g/kg and 0.7 g/kg by intragastric administration. Gastric mucosal lesions were produced by intragastric administration of absolute ethanol. Water extract of V. axillare was successively injected for 14 d and last day was injected 1 h before ethanol administration. Gastric mucosal ulcer index and ulcer inhibitory rate were counted by improved Guth methods. The tissue sections were made for pathological histology analysis. Also, we measured the concentrations of tumor necrosis factor-α (TNF-α) and endothelin-1 (ET-1) in gastric mucosal, as an index of the pro-inflammatory cytokines, apoptosis and local microcirculation. Besides, the mRNA contents of TNF-αand ET-1 were measured to verify effects on gene expression by real-time fluorescent quantitative PCR.
Results: Water extract of V. axillare significantly ameliorated the gastric mucosal lesions induced by ethanol administration (P<0.01). Pro-inflammatory cytokines, TNF-αand ET-1 were increased after ethanol administration and significantly reduced by water extract of V. axillare. The expressions of TNF-αand ET-1 mRNA were also be inhibited by water extract of V. axillare.
Conclusion: Current evidences show water extract of V. axillare is effective for defending against ethanol-induced gastric mucosal lesions, significantly inhibiting the production of pro-inflammatory cytokines and the expressions of TNF-αand ET-1 mRNA, which may be useful for inhibiting apoptosis and improving local microcirculation.

Objective To evaluate the resistance of multidrug-resistant Mycobacterium tuberculosis ( M. tb) strains to bedaquiline ( BDQ) and to analyze the relationships between their genotypes and BDQ-re-sistant phenotypes in order to provide a scientific basis for rational use of BDQ for the treatment of multidrug-resistant tuberculosis ( MDR-TB) in clinical practice. Methods A total of 387 clinical M. tb strains, inclu-ding 100 pan-susceptible strains and 287 strains isolated from patients with MDR ( MDR-TB strains) , were enrolled in this study. Of the 287 MDR-TB strains, 77 strains were collected in Chongqing in 2015 and the other strains were collected in a national drug-resistant tuberculosis survey conducted in China during 2007 to 2008. Minimum inhibitory concentrations (MIC) of BDQ against those strains were detected. Genotypes of those strains were analyzed by Spoligotyping. Differences in the resistant rates against BDQ between Beijing genotype and non-Beijng genotype MDR-TB strains were comparatively analyzed. Results MIC50 and MIC90 of BDQ against the 287 MDR-TB strains were 0. 03 μg/ml and 0. 25 μg/ml, respectively. Nineteen out of the 287 MDR-TB strains (6. 6%) were resistant to BDQ. Based on the Spoligotyping, 195 strains were clas-sified into Beijing genotype, and the other 92 strains belonged to non-Beijing genotype. Statistical analysis revealed that the BDQ-resistant rate in Being genotype strains (4. 6%, 9/195) was lower than that in non-Beijing genotype strains (10. 9%, 10/92, χ2=3. 955, P=0. 047). In addition, the MIC50 and MIC90 of BDQ against pan-susceptible strains were 0. 03 μg/ml and 0. 12 μg/ml, respectively. Sixty-three pan-sus-ceptible strains belonged to Beijing genotype and the other 37 strains belonged to non-Beijing genotype. None of the pan-susceptible strains was resistant to BDQ. Conclusion This study indicates that BDQ showed stronger in vitro antibacterial activity against the MDR-TB strains isolated in China. A correlation between non-Beijing genotype and BDQ resistance is observed in those MDR strains. MDR strains of Beijing genotype are more susceptible to BDQ than those of non-Beijing genotype.
