Objective: To investigate the application and tendency of carbapenems in the hospitals of Wuhan area.Methods: The application of carbapenems in 34 hospitals of Wuhan area during 2007-2014 was analyzed statistically in terms of consumption sum, DDDs, DDC and so on.Results: The total consumption sum of carbapenems increased year by year.Compared with that in 2007, the total consumption sum increased by 4-fold in 2014.The growing rate of total consumption sum of biapenem was the fastest among various varieties.Since 2009, three injections including meropenem, biapenem and imipenem / cilastatin predominated the market of Wuhan area, followed by faropenem with oral administration.The changing trend of DDDs was basically consistent with the total consumption sum.DDC of all the drugs was relatively high and demonstrated decreasing tendency, and that of biapenem decreased most notably, while still ranked the first place.DDC of meropenem and imipenem/cilastatin both exceeded 400 yuan.The price of faropenem fluctuated notably during 2007-2009, while increased by 2-fold in 2009 (453 yuan) and then remained stable.Conclusion: The special rectification measures show positive impact on the selection of antimicrobial agents in Wuhan area.The drug varieties are proper, while the average daily cost is still high.The government should continue to strengthen the management of antibiotics to ensure the rational use of carbapenems.

Objective To evaluate the clinical significance of the detection of the Human Papilloma Virus (HPV) DNA typing in therapy of cervical diseases. Methods 780 cases have been studied. These cases which showed HPV-DNA positive and were diagnosed by biopsy as cervical cancer or cervical intraepithelial neoplasia( CIN Ⅰ-Ⅲ) were treated by operation or physical therapy. And 6 months and 12 months after the treatment,TCT and HPV DNA test were carried out. Results The prevalence of HPV-DNA types among the 780 cases descended from HPV 16 to 52,58,18,33 and 31. Detection rates of HPV-52 and 58 were highest among the patients with CIN Ⅰ. In patients with CIN Ⅱ,CIN Ⅲ,carcinoma in situ and invasive carcinoma,the positive rate of HPV-16 was obviously higher than other genotypes,and the difference was significant (P＜0. 01 ). 520 cases were followed-up after treatment,we found that HPV-DNA subsided within 3 months to 1 year in 432 cases. 88 cases still showed the HPV-DNA positive, among this group 48 cases were cytology diagnosed as normal or inflammation,but 14 cases were ASC-US,22 cases were LSIL and 4 cases were HSIL. Cytology abnormal cases were mere often detected in patients with persistent HPV-positive than in patients with HPV-negative. Conclusion Referring patients with cervical diseases the common HPV genotypes are 16,52,58,18,33 and 31. Especially HPV-16 are closely related with cervical cancer and high-level cervical intraepithelial neoplasis. HPV-DNA turn negative in most patients in 12 months after treatment. Persistent infection of HPV-DNA is related with the pathological changes persist.

Objective To study the influence of Annao tablet on the expression of transforming growth factor beta 1 (TGF-β1) in acute graft-versus-host disease (aGVHD) murine and to explore the interventional mechanism of TGF-β1 on aGVHD. Methods Hematopoietic stem cells of male Balb/c mice were transplanted to female C57BL/6 mice for the development of aGVHD murine model. Recipient mice were divided into Annao group and blank group randomly and respectively administrated with Annao soup (a kind of Chinese herb) and 0.9% sodium chloride intragastrically. Clinical symptom, survival time and body weight were recorded at 14th and 30th day and some sections of liver, small bowel and skin were taken for histological changes. Serum level of TGF-β1 were measured by enzyme-labeled immunosorbent assay (ELISA), splenocyte protein of TGF-β1 by Western Blot and TGF-β1 mRNA by fluorescent quantitation polymerase chain reaction (PCR). Results Serum level of TGF-β1 in both groups had no statistical difference (P = 0.305), but it rose to (148.31 ± 7.95) ng/mL at 14th day and (183.48 ± 5.91) ng/mL at 30th day in Annao group, which had significant difference when compared with that in blank group (P = 0.000). IOD/IODβ-actin value of TGF-β1 protein in Annao group was 0.33 ± 0.05 at 14th day and 0.56 ± 0.04 at 30th day, which was higher than that in blank group (P = 0.000) and the expression of TGF-β1 mRNA of splenocyte in Annao group was 1.24 ± 0.04 at 14th day and 2.14 ± 0.33 at 30th day which was much higher than that in blank group (P = 0.000). Conclusion Annao tablet helps to relieve symptoms of acute GVHD by raising serum level of TGF-β1 and intensifying expression of protein of TGF-β1 and its mRNA.

0.05).The pathological severity score (on 7th day and 14th day) of the intestinal mucosa and serum MDA content (on the 14th d) of RAI group were significantly lower than those in the model control group (P

Objective To explore the influence of different administration time on antidepressant effect of seven clinical common antidepressants. Methods Male mice were randomly divided into eight groups:venlafaxine (75 mg/kg), sertraline (20 mg/kg), fluoxetine (20 mg/kg), doxepin (15 mg/kg), mirtazapine (15 mg/kg), citalopram (40 mg/kg), trazodo?ne (50 mg/kg) and control (saline) groups. Each group contained 36 mice. Drugs were administered to 6 mice per group 30 min before forced swimming test at the 6 time points (9:00, 13:00 and 17:00 as light phase and 21:00, 1:00 and 5:00 as dark phase). Forced swimming test was applied to determine the influence of dosing time on anti-immobility effect of seven antidepressants at each time point. Results Immobility time in venlafaxine group and sertraline group significant?ly decreased compared with that of control group at all time points(all P<0.05). Moreover, anti-immobility effects of ven?lafaxine, fluoxetine, mirtazapine and doxepin were better during the dark phase than during the light phase (all P<0.05). In addition, immobility time in sertraline group decreased at the late part of dark phase (5:00) and the early part of light phase (9:00) compared with other phases (P<0.05). Conclusions Most antidepressants show 24-h rhythm dependent an?ti-immobility effects, but rhythmic patterns are not completely consistent among different antidepressants. Further study is needed to explore the chronopharmacological mechanism and clinical applications of these antidepressants.

Background and purpose: Resistance of cancer cells to chemotherapy is a major clinical obstacle to successful treatment and leads to poor prognosis for the patients. MicroRNA (miRNA) plays a vital role in tumor cells response to chemotherapeutic agents. This study plans to investigate the expressions of miRNA27a and miRNA451 in ovarian cancer and breast cancer cells and its correlation with drug resistance. Methods:A2780/Taxol cells were established using stepwise selection;Stem-loop quantitative real-time PCR (stem-loop RT-PCR) was used to detect expression of miRNA27a and miRNA451 in ovarian cancer and breast cancer cells. The A2780 and A2780/Taxol cells were transfected with the mimics or inhibitors of miRNA27a or negative control (NC) RNA and the mimics of miRNA451 or NC were transfected into MCF-7/ADM cells by LipofectamineTM 2000. The expression levels of MDR1 mRNA and P-glycoprotein (P-gp) were examined using RT-PCR and Western blot respectively. MTT method was used to analyze drug sensitivity. Results:The expression of miRNA27a was an average of (2.2±0.30) times higher in A2780/Taxol cells than in A2780 cells, with a significant difference between the two groups (P<0.05). The expression of miRNA451 was lower by 84%in MCF-7/ADM cells than in MCF-7 cells, with a signiifcant difference between the two groups (P<0.05). A2780/Taxol cells transfection with inhibitors of miRNA27a showed that the levels of MDR1 mRNA was decreased by (39±0.14)%, P-gp level [(26±5.3)%] decreased compared with the NC group [(43±6.7)%], the IC50 (0.53μmol/L) was less than the NC group (6.8μmol/L), and there was a signiifcant difference between two groups (P<0.05). Transfection of A2780 cells with mimics of miRNA27a led to increase MDR1 mRNA expression by (121±0.11)%and decrease the sensitivity to paclitaxel (IC50:0.2μmol/L vs 0.06μmol/L). There was a signiifcant difference between two groups (P<0.05). Transfection of MCF-7/ADM cells with mimics of miRNA451 showed that expression of MDR1 mRNA was decreased by (65±12)%, P-gp [(31±19)%] was less than the NC group [(83±12)%], the sensitivity of cells to adriamycin enhanced and the IC50 of adriamycin (4.61μmol/L) was less than the NC group (26μmol/L), and there was a signiifcant difference between two groups (P<0.05). Conclusion:The expressions of miRNA27a and miRNA451 are deregulated in A2780/Taxol and MCF-7/ADM cells respectively, which may play vital roles in drug resistance by regulating MDR1/P-gp expression directly or indirectly.
