OBJECTIVE:To explore the relevant factors that led to the adverse drug reaction(ADR)of netilmicin.METHODS:ADR cases resulted from netilmicin reported in12kinds of Chinese periodicals from1998to2003were analyzed statistically.RESULTS:The ADR of netilmicin involved multiple organs and systems,the clinical manifestation were compli-cated and diversified,which manifested mainly on the renal toxicity,toxicity of nervous system and allergic reaction.CON-CLUSION:Clinician and pharmacists should be alert to the ADR of netilmicin and keep using drugs rationally.

Objective To investigate the clinicopathological features of thymic neuroendocrine carcinoma and its differential diagnosis. Methods Clinicopathologic analysis and immunohistochemical staining were performed in 5 cases of TNC. Results For 5 cases TNC, 3 cases occurred in men, 2 cases occurred in women. The average age was 46.8 years. They were with chest symptoms before operation. 3 cases were Ⅱ and 2 cases were Ⅲ by clinic stages. Grossly , the tumors were gray in color with areas of hemorrhage and necrosis. Histopathology of well differentiated 2 cases and poorly differentiated 3 cases. Immunohistochemically, the tumor cells were positive for CK, NSE, SyN and CgA. 3 cases were positive for PCNA, Ki67, p53. Conclusions TNC has a pleomorphic appearance of histological features with well, moderate and poorly-differentiated areas. Immunohistochemical staining is helpful in the differential diagnosis of TNC from other tumors derived from the thymus. Neither grading as neuroendocrine carcinomas nor any individual histologic parameter showed a significant association with prognosis. Initial aggressive treatment, including complete surgical excision and adjuvant radiotherapy, appears to offer the best hope for prolonged survival. Adjuvant chemotherapy also should be considered, because the incidence of distant relapse is high.

Objective To investigate the effects of medium-and long-chain fatty acid triacylglycerols on lipid metabolism in different age's male subjects with hypertriglyceridemia.Methods A randomized double-blind and controlled clinical trial was carried out among 74 male cases with hypertriacylglycerolemia.They were divided into two groups,one group was randomized to taking long-chain fatty acid triacylglycerol oil(LCT),and the other one to medium-and long-chain fatty acid triacylglycerol oil(MLCT).All cases in two groups asked to consume 20～30 g oil daily.Anthrepometric measurements and blood biochemical variables were measured at the initial and final time of the study.Results There were 34 and 33 cases left in LCT and MLCT group,respectively.A greater extent of decrease in the levels of blood TG,TC,apoB,apoA Ⅰ,apoAⅡ,apoC Ⅱ,apoC Ⅲ,apoE and LDL-C in male subjects aged less than 60 years was found in MLCT group than in LCT group after 8 weeks study(P

Objectives To study the relationship of recurrent wheezing and obesity among infants. Methods In 118 recurrent wheezing infants, the growth level are assessed based on the WHO standard. Meanwhile, all the infants are divided into two subgroups (normal-weight, overweight/obese), and the tidal breath lung function (tidal breath flow volume loop) are analyzed. Results Among the infants of 1-3 years old, for the growth level, the recurrent wheezing infants have higher index of weight, but almost the same level of height, compared with the WHO standard. For the tidal breath lung function, tidal volume (VT/kg) is significantly impaired in overweight/obese subgroup in comparison to the normal-weight subgroup. But the ratio of time to peak tidal expiratory flow (tPF) to total expiratory time (tE) and ratio of volume to peak expiratory flow (VPF) to total expiratory volume (VE), which reflect the airway obstructions to a certain extent, have no statistical differences among the two subgroups. Conclusions Rather than the height index, the weight index is significantly higher in the recurrent wheezing infants than the level of WHO standard. Compared with normal-weight patients, the tidal volume of overweight/obese recurrent wheezing in overweight/obese group is lower, but no significant differences are found for other parameters of airway obstructions.

Objective To investigate the changes of lymphocyte subsets before and after the treatment with operation and chemotherapy in patients with breast cancer.Methods Using cytometer to measure lymphocyte subsets of CD3+,CD4+, CD8+,CD4+/CD8+ and NK of 25 breast cancer patients before and after treatment.The all 25 patients were treated with operation and chemotherapy after pathological diagnosis.The article compared the figures of T cell subsets before and after treatment.Results Compared with before operation and chemotherapy,the CD8+ statistically decreased after 1~3 months of treatment (t=2.57),and NK statistically increased after 3~6 (t=-2.23).After 6 months of treatment,the patients’ CD3+(t=-2.25),CD4+(t=-2.07)were statistically lower and NK (t=-3.56)was statistically higher.There was no significant difference for other items.Conclusion Lymphocyte subsets test against breast cancer patients can reflect immuni-ty level at a certain level during treatment.But how to explain the figures in different stage against treatment effectiveness and prognosis need further research.

Objective To study the influence of valproate sodium(VPA)on neuroprotective effects of topiramate(TPM).Methods For-ty-eight 3-4 week-old male Wistar rats were randomly divided into 4 groups of 12 rats each.Group A was negative control rats,and groups B-D were rat model of epilepsy,induced by pentylenetetrazol(PTZ).The rats in 2 experimental groups were adminstered intragastrically with TPM 40 mg/kg and TPM 40 mg/kg+ VPA 200 mg/kg;2 control groups(groups A and B)with the equal amount of distilled water administration.After 2-month administration,changes of the behavior,levels of serum neuron-specific enolase(NSE)and the pathological in hippocampus were examined.Results The level of NSE in the group of TPM were significantly lower than that in masculine group,but no difference between masculine group and the TPM plus VPA.The pathological change in hippocampus were abatement in the group of TPM.Conclusion TPM plus high dosage of VPA will impaire the neuroprotective effects of TPM.
