Objective To observe the clinical efficacy of Chuankezhi acupoint injection combined with nursing health care education for treatment of patients with chronic obstructive pulmonary disease (COPD) at stable stage complicated with spleen kidney deficiency syndrome.Methods A prospective study was conducted. 118 patients with stable COPD and spleen kidney yang deficiency syndrome admitted to Hangzhou Third People's Hospital and Zhejiang Xinhua Hospital from February to April 2014 were enrolled, and they were divided into an experimental group (60 cases) and a control group (58 cases) according to the random number table. Both groups were given conventional treatment [including oxygen therapy, bronchodilators, corticosteroids, rehabilitation therapy in accord with the Global Initiative COPD (GOLD)]. Simultaneously, in the experimental group, Chuankezhi acupoint injection was additionally given, once daily for 12 weeks, and appropriate corresponding health education was mentioned. The lung function, quality of life and prognoses of the patients were regularly followed up for 9 months and compared between the two groups.Results After 12 weeks, one second forced expiratory volume (FEV1), FEV1/forced vital capacity (FVC) and maximum voluntary ventilation (MVV) per minute in the experimental group were significantly higher than those in control group [FEV1 (L): 1.57±0.42 vs. 1.35±0.35, FEV1/FVC: (58.62±4.56)% vs. (50.36±4.35)%, MVV (L/min): 60.62±7.56 vs. 56.95±6.33, allP < 0.05]. The quality of life evaluation form for COPD (QLICD-COPD) was used to evaluate the physical function, psychological function, social function and specific modules scores, showing that the above items in the experimental group were significantly higher than those in control group (total score: 74.69±8.92 vs. 68.62±8.95, physical function score: 74.16±8.55 vs. 66.31±7.15, mental function score: 78.69±9.79 vs. 72.64±8.45, social function score: 75.45±6.75 vs. 70.36±6.12, specific modules score: 67.52±6.33 vs. 61.36±6.17, allP < 0.05); Barthel index score was also significantly higher than that in the control group (75.41±9.24 vs. 68.43±7.95,P < 0.05). Within 9 months of follow-up, the incidence of acute exacerbation of COPD in the experimental group was significantly lower than that in the control group [5.00% (3/60) vs. 17.24% (10/58),P < 0.05]. The re-admission rate was also significantly less in patients in experimental group compared with that of control group [1.67% (1/60) vs. 12.07% (7/58),P < 0.05]. Conclusion Chuankezhi acupoint injection with health education for treatment of patients with COPD at stable stage and spleen kidney yang deficiency syndrome has good clinical efficacy, worthy to be applied more widely.

Objective To investigate the efficacy and safety of intravenous itraconazole in different antifungal strategies for hematologic diseases patients with invasive fungal disease. Methods The efficacy and safety of intravenous itraconazole injection in the treatment of 160 hematologic diseases patients with invasive fungal disease, including the related factors were retrospectively analysed. Results The total efficacy rate of itraconazole was 58.12 %(93/160). The response rates in therapy for undefined patients without any evidence of patients, diagnostic-driven therapy for possible IFD patients, targeted therapy for proven IFD patients were 65.82 %(52/79), 53.57 %(30/56) and 44.00 %(11/25), respectively (P=0.054). The incidence rate of itraconazole-related adverse effect was 8.13 % (13/160), and the main adverse reaction was liver impairment. Multiple-factor analysis showed that the efficacy of itraconazole for the treatment of hematologic diseases patients with invasive fungal disease was not associated with age, medical history, agranulocytosis, and initial treatment. Conclusion Itraconazole itraconazole is effective and safe in the treatment of fungal therapy for patients with hematologic diseases.

Objective To observe the effects of 2 Gy γ-ray irradiation on regulatory T cells (Tregs) and Th17 cells and immune balance of mice.Methods A total of fifty C57BL/6 male mice were randomly divided into two groups,the irradiated group exposed to 2 Gy of whole body γ-ray irradiation,and the control group sham-irradiated.At 1,3,7,14 and 28 d after radiation,changes of peripheral haemogram were detected respectively and Tregs in peripheral blood,thymus and spleen and Th17 cells in spleen were analyzed by flow cytometry.Results Compared with control group,the number of peripheral blood white cells (WBC) and lymphocyte in irradiated group reduced significantly post-irradiation (t =8.89-33.54,P ＜ 0.05),while the cell number of peripheral CD4 + CD25 + Tregs post-irradiation rose but not significantly.Thymic Treg cells increased 1 and 3 d post-irradiation(t =-6.45,-10.59,P ＜0.05),but reduced 28 d post-irradiation (t =5.34,P ＜ 0.05).Splenic Treg cells ascended obviously from 1 to 14 d post-irradiation (t =-6.82-3.89,P ＜ 0.05).After irradiation splenic Th17 cells increased at 1 d,and reached the maximal level at 3 d (t =-2.42,P ＜ 0.05),more obviously than splenic Treg cells.The reduction of Treg/Th17 ratio from 1 to 14 d post-irradiation disturbed Treg/Th17 balance and made it drift to the direction of Th17 (t =4.02-8.04,P ＜ 0.05).Conclusions Treg/Th17 imbalance plays an important role in immune injury induced by irradiation.

Objective To prepare and characterize the monoclonal antibodies (McAbs) against recombinant adhesion protein 33 (AP33) of Trichomonas vaginalis. Methods The purified recombinant fusion protein AP33 was used as antigen to immunize BALB/c mice. Sp2/0 myeloma cells were fused with the splenocytes from immunized BALB/c mice. After ELISA screening and 4 times of limited dilution, 5 positive hybridoma cell lines were obtained, and the biological properties of the McAbs were identified by Western blotting. Indirect immunofluorescent antibody test (IFAT) was performed and the inhibition effect of McAbs on the cytoadherence of T.richomonas vaginalis to HeLa cell was assayed. Results Western blotting demonstrated that 5 McAbs, designated as 4A2, 4F11, 4F8, 4E7 and 4H11, specifically combined with the recombinant AP33 of T.vaginalis. The McAbs were IgG1 isotypes. Four of them (4F11, 4F8, 4E7 and 4H11) showed parasite recognition by IFAT. Parasite cytoadherence to a monolayer of HeLa cells was inhibited in vitro with a inhibition rate of 50.08%, 65.03%, 50.70% and 49.08% by the 4 McAbs under a concentration of 200, 200, 400 and 200?g/ml, respectively. Conclusions The prepared McAbs against the recombinant AP33 show a protective inhibition on cytoadherence of Trichomonas vaginalis in vitro.

Objective:To describe the current situation in the nursing practice and their turnover intention in township health centers, and to analyze the changing potential influence in the nursing practice scope and workloads on their intention to leave those health centers. Methods:By means of a questionnaire, we conducted a survey on 167 nurses and interviewed 44 of them, all from 45 township hospitals within three provinces in China. Results:Since the healthcare system reform, the nursing workload in the township health centers significantly increased. 62% of the re-spondents considered their workload as heavy. Typically, the nursing work accounted for about 60% and the public health service work accounted for only 21% of the working hours. About 30% of the respondents were intended to leave their current job. The participating public health service was associated with intention to leave the job after con-trolling the province, workload, marital status, formal position, educational level and length of nursing service (P<0. 05). Conclusions:Since the healthcare system reform, the nursing practice scope in township health centers has been expanded and the workload increased considerably. But so far, expanding the scope of the nursing work may have potentials in reducing the intention of nurses to leave their current positions.

Objective DryLab software was used to assist high performance liquid chromatography (HPLC) method to test and isolate six Cytochrome P450 (CYP450) probe substrates.Methods Six CYP450 probe substrates were selected and the right HPLC method was developed and validated with the assistance of DryLab software.Results The new HPLC method with the assistance of DryLab software could test and isolate six probe substrates with degrees of isolation more than 2.00. The correlation coefficients (R> 0.999 8) indicated high linear correlation between the concentrations and the peak areas among six probe substrates. Recovery studies showed good results for all the probe substrat from 86.38% to 110.29%. And therelative standard deviation (RSD) ranged from 1.69% to 3.80% with its intra-day and inter-day precision ranging from 0.42% to 2.01%, and 1.36% to 2.29%, respectively.Conclusions The developed HPLC method with the assistance of DryLab could test and isolate six probe substrates with shortertime than the HPLC method alone.

Objective The alm of this study was to determine the solubility and permeability of daldzin and daldzein and the interaction of these two components.Methods With the method inChinese Pharmacopoeia and in situ single-pass intestinal perfusion model we tested the solubility and permeability of daldzin, daldzein and their interaction.Results In pH 7.4 K-R buffer the solubility of daldzin was 6 times than daldzein and both the solubility of these two components were enhanced when they were determined together. In small intestine of rat, the permeability of daldzein was 3 times than daldzin. Daldzin could enhance the permeability of daldzein but the daldzein manifested an opposite trend.Conclusion When compared to daldzin, daldzein owned a lower solubility but a better permeability. When used together, both the solubility and permeability of daldzein would be enhanced. The solubility of daldzin could be enhanced slightly but its permeability would be reduced.
