Objective To investigate the correlation between the expression of p170、GST-π 、TOPO Ⅱ and the expression of Her-2 in human breast cancer. Methods The expression of Her-2 was detected by fluorescence in situ hybridization.The expression of p170,GST-π,TOPO Ⅱ were tested in 48 breast cancer by immunohistochemical SP method,and their correlations with clinicopathological features and the expression of Her-2 were analyzed.Results The positive rate of p170,GST-π,TOPO Ⅱ were 43.8 ％(21/48),39.6 ％(19/48),56.3 ％(27/48),respectively. The expression of p170, GST-π,TOPO Ⅱ positively correlated with the expression of Her-2(P＜ 0.05).The levels of p170,GST-π,TOPO Ⅱ expression were not associated with age,primary tumor and lymph node metastasis(P ＞ 0.05).Conclusion There is great possibility of chemotherapy drug resistance in breast cancer with expression of Her-2.Expressions of p170,GST-π,TOPO Ⅱ and Her-2 have an instructive significance for chemotherapy.

OBJECTIVE:To evaluate the effect of clinical pharmacist intervention on the application of antibiotics in patients with respiratory infection from our hospital. METHODS:Each 500 patients were selected from respiratory department of our hospi-tal during Jan. to Jun. in 2016 and Jul. to Dec. in 2016. The patients were divided into pre-intervention group and post-intervention group. The application of antibiotics,the occurrence of ADR and anti-infective effects were compared before and after clinical phar-macist intervention,and the rationality of antibiotics use was evaluated. RESULTS:After intervention,the utilization rate of antibi-otics decreased from 92.60％ to 74.20％;the proportion of single drug therapy and triple and more drugs therapy were decreased significantly,with statistical significance(P<0.05). The incidence of ADR reduced from 14.20％ to 5.80％;the rate of infection control increased from 95.03％ before intervention to 97.04％;antibiotics cost decreased significantly,with statistical significance (P<0.05). The incidence of irrational drug use,nonstandard dosage,irrational drug combination and no etiological support as well as total irrational rate decreased from 7.40％,3.60％,5.80％,7.80％,20.60％ to 4.00％,1.40％,2.00％,4.20％,9.60％,with statistical significance(P<0.05). There was no statistical significance in the proportion of double drug therapy or emergency and se-vere rescue rate (P>0.05). CONCLUSIONS:The intervention implemented by clinical pharmacists effectively reduce the utiliza-tion rate of antibiotics and the incidence of ADR,improve the rate of infection control,reduce antibiotics cost and the occurrence of irrational drug use. However,there are still some problems in respiratory department of our hospital,such as irrational drug use, nonstandard dosage,irrational drug combination and no etiological support,etc. Continuous follow-up intervention is needed.

The process of protein synthesis is terminated by one of the three stop codons which are recognized by classⅠ polypeptide release factors.Subsequently, it could promote the hydrolysis of the ester bond of peptidy-tRNA, resulting in release of the nascent polypeptide.Recent results from cryoelectron microscopy, crystallography, NMR, molecular dynamic and biochemical experiments have shed considerable light on the function and structure of the classⅠ release factors.The progress in these aspects were summarized.

OBJECTIVE To explore production of ?-lactamase induced by antibiotics in Pseudomonas aeruginosa biofilm and planktonic bacteria.METHODS In vitro models of P.aeruginosa biofilm were built up.The planktonic bacteria and P.aeruginosa biofilms were exposed to different concentrations of imipenem and ceftazidime.The quantitative analysis of ?-lactamase was undertaken.The class of ?-lactamase was verified by modified cefoxitin three-dimensional test.RESULTS Both P.aeruginosa biofilm and planktonic bacteria showed significant ?-lactamase activity in the presence of antibiotics.The maximal ?-lactamase activities of both were significantly different with the statistic method of test(P

Objective:To study the expression of Survivin and p27～(kipl)and their relationship with the clinical features of gallbladder cancer.Methods:Fifty specimens of gallbladder cancer,20 specimens of chronic cholecystitis,20 specimens of polypoid lesions of gallbladder(PLG)were included,the expression of Survivin and p27～(kipl)were detected using immunohistochemistry assay.Results:In 50 cases of gallbladder cancer,39 cases expressed Survivin and 22 cases expressed p27～(kipl).There was a negative correlation between the expression of p27 and survivin(P0.05),but the expression of p27～(kipl)was related to the pathological grade,clinical stage and lymph node metastasis of gallbladder cancer(P

There should be confusion about diagnosis and treatment for multiple segments cervical myelopathy in some respects. The author reviewed the literature and combined with clinical experience, proposed a new classification for cervical myelopathy according to responsibility segment areas, which dividing into single segment,double segments (continues or jumping type), multi-segment (≥ three segments). The responsible segments determination is the premise of diagnosis and also a key to determine surgical decompression segment. Decompression only according to imaging was not desirable, surgical segment should mainly relies on clinical, imaging, electrophysiological and comprehensive analysis to avoid surgery range expansion. Surgical approach and procedures are still the focus and hotspot of cervical myelopathy treatment, and no treatment standards and corresponding guidelines to consult. The author proposes that surgical approach should advocate the individual, and surgical procedure should follow simple instead of complicate, anterior and posterior combined decompression is not necessary in most cases, and anterior and posterior fixation are not need.

Spinal muscular atrophy (SMA) is a group of neuromuscular disorders, caused by degeneration of the motor neurons in the anterior horn of the spinal cord, with prevalence of about 1 in 6000 to 1 in 10000 in newborn. The gene carrying frequency is about 1 in 40 to 1 in 50 all over the world. SMA is one of the most common autosomal recessive diseases causing infant death. SMA mainly refers to SMN1 dependent caused by SMN1 gene mutations. Noninvasiveness and specificity make genetic testing a recommended method for diagnosis of SMA. In addition to conventional methods such as neural nutrition, muscle exercise, etc., there is no specific treatment for SMA up to now. Nevertheless, HDAC inhibitors deserve attention as they are the only drugs completed Phase Ⅲ clinical trials to date. Furthermore, other ways as small-molecule SMN enhancers, induced pluripotent stem cell (iPSC), antisense oligonucleotides to correct SMN2 splicing, etc, were still on the way of in vitro stage at present.

This study was aimed to observe the protective effect of astragalus on bones of vitamin D deficiency rat model. A total of 30 male SD rats were randomly divided into 3 groups, which were the control group, model group, and the astragalus group. The experimental period was 8 weeks. After the experiment, enzyme immunoassay was used for the detection of serum 25 hydroxy vitamin D3 [25 (OH)VD3], fibroblast growth factor-23 [FGF-23], Klotho, and HE staining of femur. The results showed that compared with the normal control group, the vitamin D deficiency rat model group had a decrease in both serum 25 (OH)VD3 and Klotho, and a increase in FGF-23, which meant the ex-istence of osteoporosis. Compared with the model group, the astragalus group had a decrease in both the serum 25 (OH)VD3 and FGF-23, and a increase in Klotho, which meant the osteoporosis of the astragalus group had been im-proved significantly. It was concluded that astragalus can regulate FGF-23 and Klotho in vitamin D deficiency rats in order to have a protective effect for bones.
