Objective To evaluate the efficacy of supportive psychotherapy on patients with cardiac neurosis. Method 32 patients with cardiac neurosis were treated with a comprehensive measure consists of adequate drug therapy and supportive psychotherapy. Symptom Checklist 90 (SCL - 90) was rated. Result Among the 9 factors of SCL - 90, scores of somatization, obsessive - compulsive, interpersonal relationship, depression, anxiety and phobic anxiety factors were significanly higher than that of normal controls. After treatment, the scores of somatization, depression, anxiety and phobic anxiety were statistically reduced. Patient- reported improvement efficacy was 84. 38%.Conclusion Adequate drug therapy together with supportive psychotherapy has reliable efficacy on patients with cardiac neurosis.

OBJECTIVE:To study the compatible stability of gatifloxacin for injection with metronidazole disodium phos-phate in sodium chloride injection.METHODS:The contents of2constituents of the mixed solution stored at25℃within8hours was determined by dual ultraviolet wavelength spectrophotometry,and the appearance,pH value of the mixture were compared with those before.RESULTS:There was no significant change in the content of gatifloxacin after mixing,while the content of metronidazole disodium phosphate has a slight reduction,no significant changes were noted otherwise.CONCLUSI_ ON:Gatifloxacin for injection is compatible with metronidazole disodium phosphate in sodium chloride injection if at25℃within4hours'mixing.

OBJECTIVE:To study the compatible stability of gatifloxacin for injection in combination with aciclovir for injection in 0.9% sodium chloride injection or 5% glucose injection.METHODS:Changes in appearance and pH value of gatifloxacin in combination with aciclovir within 8 hours after mixing were observed and determined under room temperature(20?1)℃,respectively,and the precipitates in the mixture underwent infrared spectrum analysis.RESULTS:White flocculent precipitate was noted in the mixture within 1 hour of mixing,which was proved as a new substance by infrared spectrum analysis. CONCLUSIONS:There is incompatibility between gatifloxacin for injection and aciclovir for injection.

OBJECTIVE: To explore the causes,patterns and features of drug induced abnormal body temperature.METHODS: 215 articles covering total 1 540 cases of drug-induced abnormal body temperature,published during Jan.1994～ Dec.2005 in 130 Chinese medical journals,were sorted from CNKI and CHKD and consolidated for analysis.RESULTS: Abnormal body temperature cases induced by antimicrobials,traditional Chinese medicines and central nervous system drugs were listed among the top three in number;injections generated the highest proportion of abnormal body temperature cases.Drug-induced abnormal body temperature was not related to sex and age.CONCLUSION: To ensure safe use of drugs,clinicians should inquire about patients' medication history before drug administration,strictly follow medication indications and closely observe the reactions after drug administration.

OBJECTIVE:To study the compatible stability of gatifloxacin for injection and cimetidine injection in 0.9% sodium chloride injection or in 5% glucose injection.METHODS:Changes in appearance and pH value of gatifloxacin in combination with cimetidine within 8 hours after mixing were respectively observed and determined under room temperature(20?1)℃,and the content was determined by UV spectrophotometry.RESULTS:No significant change was seen in appearance and pH value after two hours of mixing of the two agents.But after four hours of mixing,the content of cimetidine went up in both solvents,and its pH value rose slightly in 0.9% sodium chloride injection.CONCLUSION:Gatifloxacin for injection can be mixed with cimetidine injection in 0.9% sodium chloride injection or 5%glucose for injection to use,but the compatible liquid should be used up in 2 hours.

OBJECTIVE:To observe the compatibility of gatifloxacin for injection with cefradine for injection in 5% glucose injection and in 0.9% sodium chloride injection respectively.METHODS:At room temperature for8hours the change in appearance and pH value were observed,while the content was determined by UV spectrophotometry as well.RESULTS:There was no evident change in appearance after the mixture,but the pH value and concentration changed significantly.CONCLUSIONS:There exists incompatibility between gatifloxacin for injection and cefradine for injection.

AIM: To investigate the effect and mechanism of Jingui Shenqi Pill(JGSQ) on pulmonary fibrosis. METHODS: Pulmonary fibrosis was induced by bleomycinA5 in SD rats.Rats in drug group were killed after being treated by taking JGSQ daily for 28 days.The lungs of all rats were harvested for histopathological studies.The contents of tumor necrosis factor ?(TNF-?)in lungs were measured and compared. RESULTS: The degree of the alveolitis and pulmonary fibrosis, the contents of TNF-? in lungs increased significantly in the model group as compared with the normal group and the JGSQ treated group(P

Objective: To analyze the influencing factors in thrombin titration for the determination of anticoagulant activity of Whitmania Pigra Whitman. Methods: The white porcelain plates were used as the titration carriers instead of tubes in the titration ( called white porcelain method for short) . The effect of different carriers, interval time of titration and thrombin concentration on the results of anticoagulant activity test was studied. Results:Under the same conditions, the anticoagulant activity was more accurate and stable using white porcelain method. Using white porcelain method with 20 u·ml-1 or 10 u·ml-1 as the thrombin concentration and titrating 5μl each time, once every minute, the thrombin consumption volume was linear with the sample concentration within the range of 0. 125-0. 333 g·ml-1(r20 =0. 961 and r10 =0. 992), and the anticoagulant activity respectively was (33. 08 ± 2. 64) and (31. 24 ±1.32) u·g-1(RSD20 =8.0% and RSD10 =4.2%). As for a certain sample concentration (0.333 g·ml-1), the theoretical error of determination was not more than 10% and 5%. Conclusion:The improved white porcelain method is more suitable for determining anticoagulant activity of Whitmania Pigra Whitman with more stable results and accurate end point states than tube method. Under the conditions of 10 u·ml-1 thrombin concentration, titrating 5μl each time, once every minute, the linearity, accuracy and precision are all promising.
