【Objective】To investigate the therapeutic effect of Zhuyin Capsule(ZC)for the treatment of congestive heart failure(CHF).【Methods】Fifty SD rats were randomized into five groups: A(pseudo-operation),B(model),C(treated with hydrochlorothiazide 14.29?mg?kg~(-1)?d~(-1)),D(treated with ZC 0.26?g?kg~(-1)?d~(-1))and E(treated with ZC 0.51?g?kg~(-1)?d~(-1)).Except group A,rat models of CHF were established in other groups.Thirty-five days after the modeling,groups C,D and E were treated with corresponding drugs according to the experimental design for 2 days.Cardiac function and the pathological features of heart,liver and lung were examined.【Results】The changes in group A were as follows: heart rate became fast,blood pressure decreased,left ventricular end diastolic pressure(LVEDP)increased,the maximum rate of left ventricular pressure rise(+dp/dt_(max))decreased,ventricular cavity became enlarged and the wall was thin,and there appeared myocardial fibrosis,congested liver and edema in pulmonary alveoli,indicating the success of CHF model.High-dose ZC could relieved the above changes(P0.05).【Conclusion】ZC can decrease the preload and afterload of the heart,and reduce the pathological changes of heart,liver and lung in CHF rats,which may be one of its therapeutic mechanisms.

Objective: To investigate the regulation of CYP3A4 and P-gp by berberine hydrochloride ( BBR) via pregnane X re-ceptor (PXR) pathway. Methods: pLKO. 1-PXR vector, a lentivirus plasmid expressing PXR shRNA, was packaged into 293T cells. Human hepatoma (HepG2) cells were infected with the lentivirus and the cell clones stably expressing PXR shRNA were selected by puromycin according to pLKO. 1 vector characteristics. Real-time RT-PCR and Western blot were used to evaluate CYP3A4 and P-gp mRNA and protein in berberine treated HepG2 cells and PXR-silenced HepG2 cells. Results: The PXR expression in PXR silenced cells significantly decreased (P<0.01) when compared with that in HepG2 cells, while there was no significant difference (P >0. 05) in the expression of CYP3A4 and P-gp between the groups. Compared with that in HepG2 cells, the inhibition of berberine on the mRNA and protein expression of CYP3A4 and P-gp in PXR-silenced HepG2 cells was weakened (P<0. 05 or P<0. 01). Conclu-sion: Berberine can regulate the expression of CYP3A4 and P-gp via PXR signaling pathway, while it is not the only one.

Objective: To investigate the association between ABCC2 gene polymorphisms and cyclosporine-induced liver injury in re-nal transplant recipients. Methods: The renal transplant recipients were divided into the liver injury group and the control group. Five single nucleotide polymorphisms ( rs4919395, rs2804398, rs4148394, rs4148397 and rs3740065) of ABCC2 were detected by high-throughput technique. The genotypes and haplotypes were analyzed between the groups. Results: There were 35 patients and 182 patients respectively in the liver injury group and the control group. No significant differences in alleles and genotypes were found between the groups (P>0. 05), and the SNP haplotypes showed no significant difference between the groups (P>0. 05). Conclusion: There is no association of ABCC2 polymorphisms (rs4919395, rs2804398, rs4148394, rs4148397 and rs3740065) with the liver injury induced by cy-closporine.

Objective: To describe the distribution and drug resistance of pathogens at hematology department of Jiangsu Province from 2014 to 2015 to provide reference for empirical anti-infection treatment. Methods: Pathogens were from hematology department of 26 tertiary hospitals in Jiangsu Province from 2014 to 2015. Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or agar dilution method. Collection of drug susceptibility results and corresponding patient data were analyzed. Results: The separated pathogens amounted to 4 306. Gram-negative bacteria accounted for 64.26%, while the proportions of gram-positive bacteria and funguses were 26.99% and 8.75% respectively. Common gram-negative bacteria were Escherichia coli (20.48%) , Klebsiella pneumonia (15.40%) , Pseudomonas aeruginosa (8.50%) , Acinetobacter baumannii (5.04%) and Stenotropho-monas maltophilia (3.41%) respectively. CRE amounted to 123 (6.68%) . Common gram-positive bacteria were Staphylococcus aureus (4.92%) , Staphylococcus hominis (4.88%) and Staphylococcus epidermidis (4.71%) respectively. Candida albicans were the main fungus which accounted for 5.43%. The rates of Escherichia coli and Klebsiella pneumonia resistant to carbapenems were 3.5%-6.1% and 5.0%-6.3% respectively. The rates of Pseudomonas aeruginosa resistant to tobramycin and amikacin were 3.2% and 3.3% respectively. The resistant rates of Acinetobacter baumannii towards tobramycin and cefoperazone/sulbactam were both 19.2%.

The rates of gram-positive bacteria resistant to vancomycin, linezolid and teicoplanin were still low. MRSA accounted for 39.15%.

Objective: To explore the menopausal symptoms and quality of life of hormone receptor positive (HR+ ) breast cancer patients at different endocrine therapy time. Methods: The HR+ breast cancer patients who were pathologically confirmed from 2011 to 2017 in the Sichuan Cancer Hospital were divided into three groups according to endocrine therapy time (<12 months, 12~36 months, >36 months) and analyzed by a cross-sectional study. The Menopausal symptoms and quality of life of these patients were measured using the modified Kupperman scale and the functional assessment of cancer therapy-breast cancer (FACT-B) scale. The differences of menopausal symptoms among different time groups and drug groups were analyzed by Chi-square test. The differences of quality of life and the effects of menopausal symptoms on quality of life were tested by covariance and multiple linear regression analyses. Results: The average score of menopausal symptom of 167 patients was 14.5±7.6 and the prevalence rate was 87.4% (146/167). Among all of the menopausal symptoms, the prevalence rate of insomnia was the highest (73.7%, 123/167). Besides insomnia and excitement, hot flashes was more prevalent in selective estrogen receptor modulator (SERM) users (64.8%, 79/122) , while osteoarthritis was more prevalent in aromatase inhibitor (AI) users (62.2%, 28/45). The total score of FACT-B of Patients was 104.5±15.5, and the compliance rate was up to 89.8% (150/167). However, the condition of each dimension was different, the compliance rates of social/ family and functional dimension were lowest, which were 73.0% (122/167) and 50.9% (85/167), respectively. The menopausal symptoms of patients at different time groups were 15.0±1.3, 14.0±6.9, 14.5±7.4, respectively, and the total score of FACT-B of patients at different time groups were 102.7±17.8, 105.0±12.9, 105.6±16.7, respectively, without significant differences (both P>0.05). Multiple linear regression analysis showed that menopausal symptoms impaired the quality of life of SERM users during the endocrine therapeutic period. The standardized regression coefficients of three time groups were -0.67, -0.30, -0.50, respectively, with the lowest effect on 12~36 months group. Conclusion HR+ breast cancer patients will have a poor function recovery and social/ family return, who need more attention. Menopausal symptoms are common problems during endocrine therapy, and active measures should be taken to improve patients′ quality of life.
