AIM　To improve the treatmemt efficacy and reduce the side effect of carboplatin (CBP), the antitumor drug was incorporated into niosomes (NS). METHODS　Lung targeted niosomes of CBP (CBP-NS) were prepared by the method of hand shaking. The ultraviolet absorption spectrophotometric method was used for the determination of CBP. The method of dynamic dialysis was used for in vitro release of CBP from CBP-NS. The S-180 lung neoplasms models were established by iv cancer cells in mice. The number of pulmonary nodules was examined for evaluating the therapeutic efficacy. RESULTS　The data showed that the mean diameter of CBP-NS was 3.72 μm, with a span of 0.66. The entrapment ratio of CBP in CBP-NS was 29.2% and the CBP-NS were stable for three months stored at 3℃-5℃, 15℃-25℃ or 37℃ (relative humidity 75%). The release profile in vitro could be described by a biexpotential equation. The calculated values of the three targeting parameters indicated that CBP-NS showed good targeting efficiency. The results of therapeutic trials showed that the antitumor effects were significantly increased by injection of CBP-NS compared with CBP in the treatment of mice with lung carcinoma. CONCLUSION　The results indicated that CBP-NS have good targeting efficiency in vivo, and the biodegradable CBP-NS may decrease the side effects of carboplatin and improve its therapeutic efficacy.

Objective To explore the effect of heterosexual interaction training on rehabilitation in first-episode schizophrenic patients. Methods 246 patients of first-episode schizophrenic were divided into the study group and the control group with 123 cases in each group at random. Both groups were treat-ed with conventional pharmacotherapy under the orders of physicians in hospital. For the study group,both the male patients and the female patients took part in entertainment treatment activities,eating and interaction training together during the day, then they lived separately at night. Two groups were evaluated with BPRS and ITAQ before treatment and at the 2nd, 4th, 6th, and 8th week after treatment. Results The BPRS scores of the study group were significantly lower than the control group after 4th, 6th,and 8th week. The ITAQ scores of the study group were significantly higher than the control group after 4th, 6th,and 8th week. Conclusions The application of heterosexual interaction training in schizophrenic patients can alleviate illness condition, improve treatment compliance and rehabilitation.

The linear range of isoimperatorin was 0. 596-5. 960 μg·mL-1 and the regression equation was Y=10 661X+1 073 (r=0. 999 9). The average recovery was 99. 25% (RSD=0. 74% ) and 98. 94%(RSD = 0. 63% ),respectively. Conclusion The method is accurate, rapid and reliable, and can be used to determine imperatorin and isoimperatorin in huoxiang zhengqi oral liquid.

Objective To observe the effects of puhnonary rehabilitation on the symptoms and quality of life of persons with chronic obstructive pulmonary disease (COPD).Methods COPD patients were recruited from a hospital and community health centers and given pulmonary rehabilitation in the community.The rehabilitation program included health education and nutrition guidance,medication,breathing exercises,and physical exercise.Each patient was followed up every 4 weeks by telephone.The outcome measures included pulmonary function (FEV1％,FEV1/FVC％),St George's questionnaire (SGRQ),the Medical Research Council scale (MRC),Borg scoring,evaluation of anxiety and depression,the six-minute walk test (6MWT),and an evaluation of nutritional status.All of the patients were observed for one year.Results A total of 85 patients completed the program and were included in the final statistical analysis.There was no difference in FEV1 ％ before and after rehabilitation.Six-minute walking distance improved significantly in statistical terms but the average increase was only from (416.1 ±99.84)m to (437.51 ±116.17)m.The SGRQ scores decreased by an average of 4.8 points after a year of rehabilitation,with significant improvements among the moderately and severely impaired.Incidents of COPD exacerbation also decreased significantly.Patients with a low body mass index had the greatest SGRQ score improvments.Few patients showed depression or anxiety in this research population.Conclusions Pulmonary rehabilitation in the community can improve exercise tolerance and the quality of life for persons with COPD,reducing incidents of acute exacerbation.Patients may benefit from such pulmonary rehabilitation regardless of disease severity.The compliance was good despite the infrequent monitoring.Pulmonary rehabilitation in the community is worthy of more widespread use.

Aim To observe the optimal temperature and optimal pH of uricase-catalase liposomes(UCALP) and free uricase(UAE), and study the abilities of UCALP to reduce uric acid and hydrogen peroxide in mice with hyperuricemia.Methods UCALP were prepared by reverse phase evaporation, optimal temperature and optimal pH of UCALP and UAE were determined, respectively.Mouse model of hyperuricemia was established by intraperitoneally injection of uric acid, and the model mice were intravenously injected UCALP and UAE, respectively, then the serum concentration of uric acid and hydrogen peroxide in mice at different time points were measured by the assay kits, respectively.Results Optimal temperature of UCALP and UAE was 40℃, and optimal pH was 8.0 and 8.5, respectively.UCALP could more significantly lower uric acid level of hyperuricemia mice than that of UAE, and the concentration of hydrogen peroxide in UCALP group was lower than in UAE group.Conclusion UCALP can effectively decrease the level of uric acid and control the level of hydrogen peroxide in mice with hyperuricemia.

Aim To prepare the novel pyridostigmine bromide nanoemusion(PPNE)and study its release in vitro, and to investigate the intestinal absorption. Methods Pyridostigmine bromide (PB)and PPNE were tested by HPLC in pH 1 .2 HCl,pH 6.8,pH 7.4,pH 7.8 PBS.Rat single pass intestinal perfusion method was employed to investigate the absorption mechanism of PB and PPNE.Results PB release rate was faster than PB in the four release media;the intes-tinal absorption rate constant(Ka )and apparent perme-ability coefficient(Papp)of PPNE were increased in the duodenum,jejunum,ileum and colon segments.PB and PPNE had significant difference in the duodenum, jejunum,ileum and colon segments by t test (P <0.05).Conclusions PPNE can improve the bioavail-ability of drugs,increase the drugs permeability,sig-nificantly improve the absorption of the drugs in the in-testinal segments. PPNE has obviously sustained effects.
