Objective To study the therapeutic and protective effect of low tidal volume(LTV) ventilation in children with acute respiratory failure.Methods Forty-eight patients with respiratory failure were enrolled in our study.The patients were suffered from severe infection,trauma or after major operation.Besides general treatments,they were all given ventilation with LTV.Blood gas,ventilation parameters and complications related to ventilation were also measured.Results No significant difference was found between the patients with high tidal volume(HTV) and those with LTV in the results of improving respiratory acidosis.But the incidence of(ventilated-)induced lung injury(VILI) was lower in LTV patients.Conclusion LTV ventilation is preferable for children with acute respiratory failure and beneficial for alleviation of VILI.

OBJECTIVE:To establish culture management concepts in hospital pharmacy professions and to standardize the behaviors among pharmacists,patients,colleagues and other health professionals.METHODS:Theories about the corpo?ration management development,definition of corporation culture,the3levels of corporation culture management and the operation of corporate culture construction were briefly introduced;the hospital pharmacy profession culture management principle was established with a reference of the corporate culture management concept at all times and in all over the world.RESULTS:Harmonious,friendly,kindly and placatory atmosphere can be established through the culture construction in material,system,behavior and spiritual levels;pharmacists should be urged to win the trust of patients so as to achieve the best therapeutic effects for the patients.CONCLUSION:The establishment of hospital pharmacy profession culture management principle can inspire pharmacists'passion and enthusiasm for work;thereby the development of pharmaceutical enterprises can be promoted.

Objective An investigation was conducted to assess the chemopreventive effects of celecoxib, a selective cyclooxygenase(COX)-2 inhibitor, on a rat colon carcinogenesis model induced by dimethylhydrazine (DMH). The results were compared with those of sulindac. Methods Thirty-two 8-week-old female Sprague-Dawley rats were randomly divided into four groups (n=8 each):Group A rats were treated with DMH(120 mg/kg wt, single subcutaneous injection) alone and group B rats were treated with saline alone. Group C rats were pre-treated with sulindac (320 mg/kg feedstuff) and group D rats pre-treated with celecoxib (1500 mg/kg feedstuff) for 7 days before DMH initiation. The animals were killed at the end of the experiment (week 5) and the aberrant crypt foci(ACF) and aberrant crypt(AC) of the colonic mucosa were assessed after being stained with methylene blue. Results In group A(DMH only), the average numbers of ACF and AC were 182.4?93.43 and 262.8?197.8 respectively. In group B (saline group) rats, no ACF was found. In group C (sulindac group) rats, the average numbers of ACF and AC were 91.25?48.98 and 139.60?68.52 respectively, both of them were decreased significantly as compared with those in Group A (P

OBJECTIVE To study and analyze the detected rate,distribution of fungal species and drug resistance of 137 strains of infecting urinary system epiphytes in local area over the last three years to provide foundation for the reasonable clinical use of anti-epiphyte medicines.METHODS The epiphytes isolated from epiphyte culture of midstream urine were tested with API 20C AUX and their drug sensitivity was tested with Rosco disk diffusion method.RESULTS Of 137 strains isolated in the experiment,57 were Candida albicans,accounted for 41.6%;48 were C.tropicalis,accounted for 35.0%;and 19 were C.glabrata,accounted for 13.9%.And their drug resistances to fluconazole were 5.2%,8.3% and 36.8%,respectively.All tested epiphytes were sensitive to amphotericin B.CONCLUSIONS The results indicated that the isolation rate of epiphytes in local area is high.The majority of tested epiphytes are C.albicans and C.tropicalis,which are comparatively sensitive to zole medicines.C.glabrata is comparatively resistant to zole medicines.Amphotericin B is the most effective medicine to cure epiphytic infections of urine system.

Objective To evaluate the immunotoxicity effect of Liver targeting interferon (IFN -CSP) on mice.Methods Mice were randomly divided into five groups:low, middle and high dose of IFN-CSP, solvent control group(saline) and Positive control group (cyclophosphamide).They were injected subcutaneously for 2 weeks.Delayed hypersensitivity test was used to determine the cell immunefunction and plaque forming cell assay was used to determine the humoral immune function.Results There was no significant difference of the the index of immune organ and the ear swelling degree between IFN-CSP groups and control group.There was also no significant difference on hemolytic plaque test between them.Conclusion IFN-CSP has no significant effect on both cellular immunity function and humoral immune function of mice, this results will provides the basis for further safety evaluation.

Objective To investigate the imaging characters of abdominal cocoon.Methods Six cases of abdominal cocoon proved by surgery and pathologic findings were retrospectively analyzed. Abdominal plain X-ray and CT were performed in 6 cases.The gastrointestinal barium meal series were undergone in 4 cases.The imaging findings were analyzed.Results Abdominal plain X-ray suggested intestinal obstruction in 3 of 6 cases.The gastrointestinal barium meal showed"cauliflower sign"or "concertina pattern"in all of the 4 cases;CT images revealed a conglomeration of multiple small bowel loops in all 6 cases and the intestinal loops seemed to be encapsulated in a membranelike sac.Conclusion The imaging features of gastrointestinal barium meal and CT scan could suggest the diagnose of abdominal cocoon.

Objective To investigate the effect of Clopidogrel on the plasma endothelin(ET)and calcitonin gene related peptide(CGRP)in patients with unstable angina pectoris(UAP).Methods Patients with UAP were divided into two groups,the regular treated group(n =50)was treated with Isoket and the Dansben group(n =50)was treated with combined Isoket and Clopidogrel.The plasma ET and CGRP were measured before and after treatment by radioimmunoreactive assay.Data were compared between the two groups and also compared with those measured in 20healthy subjects for control.Results ET level was significantly higher and CGRP level was lower in UAP patients than that in healthy subjects(P ＜ 0.05).After Clopidogrel treatment,ET was significantly decreased(P ＜ 0.01)and CGRP increased(P ＜0.05)in combined treatment group compared with patients received lsoket only.Conclusion Clopidogrel was an effective drug for UAP treatment,which could efficiently regulate the ET and CGRP metabolism.

Objective To analyze the long-term results of fractionated stereotactie radiotherapy(FSRT)for the local residual lesion after the first course of radiotherapy for nasopharyngeal carcinoma.Methods From July 1997 to July 2002,46 patients were treated with FSRT.According to the 1992 Fuzhou staging system,the number of patients was 1,6,30 and 9 with stage Ⅰ,Ⅱ,Ⅲ and Ⅳ disease,respectirely;3,11,27 and 5 with T1,T2,T3 and T4 tumor,respectively;14,16,12 and 4 with N0,N1,N2and N3 disease.Radiotherapy was delivered to tumors with the total of dose 68-70 Gy in 7-8w.Chemotherapy(2 cycles of PVF or POF)was given to the patients with stage Ⅲ and Ⅳ a disease.FSRT was given to the residual disease with the total dose of 18-24 Gy in 3 fractions with an interval of 3-7 days.The reference dose line was 70%-90%.Resuits CR and PR rates in this group were 61%and 39%,respectively.The overall survival rates of each year from 1- to 5-year were 100%,87%,83%,78%and 76%.The 1-,3- and 5-year disease-free survival rates were 100%,93%and 89%;The distant metastasis-free survival rates were 100%,85%and 79%;The local-regional control survival rates were 100%,94%and 91%.Seventeen patients who died during the follow-up period were 1 for local cervical lymph node recurrence,2 for fatal nasopharyngeal hemorrhage,4 for local nasopharynx recurrence,and 10 for distance metastases. Conclusions Fraetionated stereotactic radiotherapy is safe and effective for the patients with residual lesion of nasopharyngeal carcinoma at the primary site after radiotherapy.The optimized fractionation and total dose requires the further investigation.
