Acta Pharmaceutica Sinica 2001;36(4):303-306
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.

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.

Objective: To explore antitumor responses induced by recombinant vaccinia viruses expressing a p53 antigenic peptide (rVV-p53M) and enhanced effect of recombinant vaccinia viruses expressing costimulatory molecule B7 (rVVB7). Methods: A 135 Cys to Tyr point mutation p53-transduced P815 mastocytoma (P815-mp53) was used as an experimental tumor and the p53 protein as the model of tumor associated antigen. rVV-p53M and rVV-B7 were used as vaccine to test their induction of CTL and antitumor immunity. Results: Immunization of BABL/c mice with rVV-p53M could elicit specific CTLs, which could specifically lyse P815-mp53 cells. Immunization of mice with rVV-p53M could survive a part of mice challenged with 1×106 P815-mp53. Treatment with rVV-p53M could significantly prolong the survival oftumor-bearing mice. Admixture at 1:1 ratio of rVV-p53 M and rVV-B7 could enhance antitumor responses induced by rVV-p53M. Conclusion: Immunization with recombinant vaceinia virus expressing antigenic peptide is a useful alternative to peptide-based vaccine. Costimulatory molecule B7 can enhance antigenic peptide to induce antitumor responses.

Objective To observe the regularities of distribution of TCM syndrome types and correlation between TCM syndrome types and cardiovascular prognosis risk factors of elderly hypertensive patients in three different urban and rural communities.Methods Totally 299 elderly hypertensive patients who conformed to the hypertensive diagnostic criteria from 896 respondents which participated in the health monitoring questionnaire drafted by health management team of China Academy of Chinese Medical Sciences were screened. The syndrome types were differentiated according to Guiding Principle of Clinical Research on New Drugs of Traditional Chinese Medicine (for Trial Implementation). The levels of some risk indicators, such as blood glucose, blood lipid, CREA, ET, Hcy and mALB were measured by radioimmunoassay, enzymatic cycling assay and other methods. Age, gender, BMI and pulse pressure were recorded.Results The TCM syndrome types of 299 elderly hypertensive patients were deficiency of yin and yang type (74 cases), hyperactivity of yang due to yin deficiency type (65 cases), blood stasis syndrome type (62 cases), stagnation of phlegm-dampness type (61 cases), hyperactivity of liver-fire type (37 cases). Single factor analysis showed that there existed statistical significance among BMI, FBG, GHbA1c, CREA, TC, LDL-C, ET, Hcy and mALB in the 5 TCM syndromes (P<0.05,P<0.01), and the statistical significance was more apparent in the stagnation of phlegm-dampness type, blood stasis syndrome type and hyperactivity of yang due to yin deficiency type. Discriminant analysis showed BMI and Hcy have certain reference value for the diagnosis of TCM syndrome types in elderly hypertensive patients. Binary-Logistic regression analysis showed that the course of disease had a positive correlation with syndrome of deficiency of yin and yang.Conclusion Compared with other types of elderly hepertensive patients, stagnation of phlegm-dampness type and blood stasis syndrome type are more closely related to hypertension cardiovascular prognosis risk factors.
