Objective To investigate the roles of T GFβ1 and TGFβ1 typeⅠrecepter(TβRⅠ) in development of myocardial hypert rophy and myo cardial interstitium remodelling in renovascular hypertensive rat. 　Methods TGFβ1 and TβRⅠwere evaluated by qualitative and semi -qu antitative immunohistochemical staining to explore their distribution and ex peression in left ventricular tissue. Van Gieson staining were used in the stud y of total collagen in left ventricular interstitial tissue. 　Results Compared with sham-operated rat(SOR),the expression of T GFβ1 andTβRⅠ in left ventricular tissue were significantly increased in RHR(P <0.01 all). In RHR the antibody to TGFβ1 reacted primarily with cytoplasma a nd myo cardial interstitium while antibody to TβRⅠreacted mainly with myocyte membran es with weak labeling in myocardial interstitium. In SOR,very mild labeling for TGFβ1 and TβRⅠin myocardiun was found with no labeli ng in myocardial interstitium. Correlative analysis revealed that TGFβ1 or T βRⅠ was positively correlated with left ventricular mass index(LVMI),negativel y correlated with grey level of myocardial total collagen. Conclusions TGFβ1 and TβRⅠmay play important roles in develo pment of left ventricular hypertrophy and myocardial interstitial fibrosis.

Objective:To explore the value of clinical pharmacist in clinical treatment through the pharmaceutical care on a patient with Japanese B encephalitis complicated with pulmonary infection. Methods:Clinical pharmacist participated in the whole treatment process and gave suggestions on the selection,dosage and course of the drugs prescribed for anti-virus, anti-epilepsy and anti-infection by focusing on the drug interactions and adverse reactions. Results:The treatment course of the patient was smooth, and the pathoge-netic condition was brought under control gradually while no obvious adverse drug reactions occurred. Conclusion:The work of clinical pharmacist can help to optimize treatment programs to ensure the safety and effectiveness of medication.

Objective:To explore the value of clinical pharmacists in the clinical treatment of a patient with Guillain Barré syn-drome through pharmaceutical care. Methods:Clinical pharmacists participated in the entire treatment process and gave rational sug-gestions about the selection,dosage and course of the drugs,such as glucocorticoid,immunoglobulin and antibiotics. Meanwhile,clini-cal pharmacists focused on the adverse drug reactions. Results:The patient′s condition was controlled and improved gradually. During the hospitalization,the patient developed skin rash and abnormal liver function,while the symptom was improved after the anti allergy and liver protection treatment,and no obvious effect on the primary disease was shown. Conclusion:Clinical pharmacists can help to optimize treatment regimen in order to ensure the safety and effectiveness of patients’medication.

Objective To measure Bolton index with malocclusions in Shanghai Fengxian district,and ana-lyze the distinction among different malocclusions patients in respect of gengder,age,and different Angle classifica-tion.Methods Measure Bolton index of plaster models of 348 eligible malocclusions patients who were selected ran-domly from Shanghai Fengxian District,and divided them into different groups by gender,age and Angle classification. Then,Bolton overall ratio and Bolton anterior ratio among these groups were analyzed and compared.Results The results showed that there were no significant differences of Bolton analysis in respect of gender or age(all P >0.05). It exsisted obvious differences in anterior ratios among the three Angle malocclusion class(P <0.05).Bolton anterior ratios were (79.88 ±3.15)%,(78.91 ±2.86)% and (80.59 ±1.55)%,mean of Class I and mean of ClassⅢwere bigger than that of Class Ⅱ.Bolton overall ratios of Angle class Ⅰ,classⅡ and class Ⅲ were (79.88 ± 3.15)%,(79.88 ±3.15)% and (79.88 ±3.15)%,and there were no obvious differences in overall ratios among them.Conclusion Bolton index with malocclusions for Shanghai Fengxian District accord with normol Bolton index of our country.Gender and age are not the influencing factors of Bolton index in Fengxian District.Bloton index anomalies are the important fator in malocclusions.We should pay more attention to the Bolton analysis of class Ⅱ malocclusions in clinical practice,and draw up a treatment plan combined with specific classification.

Objective To screen the optimal medium formula for obtaining high proliferation rate and differentiation rate of protocorm-like body ( PLB) of Dendrobium officinale Kimura et Migo ( D.officinale) . Methods We observed the effect of different concentrations of phytohormones such as 6-benzylaminopurine (6-BA) , 1-naphthaleneacetic acid ( NAA) , 2,4-dichlorophenoxyacetic acid ( 2,4-D) and kinetin ( KT) , or their combinations together with organic additives such as potato extractive ( PE) , banana extractive ( BE) , apple extractive ( AE) and coconut milk ( CM) on the proliferation and differentiation of PLB of Dendrobium officinale Kimura et Migo. Results 6-BA, NAA and KT at certain concentrations were beneficial to the proliferation and growth of PLB, and when the concentration of KT was 1.0 mg/L, 50-d PLB proliferation times reached to 7.20. 2,4-D had obvious inhibitory effect on PLB proliferation and growth. The combination of 6-BA, NAA and KT showed stronger effect on PLB proliferation than the phytohormones used alone, and the combination of 0.5 mg/L 6-BA, 1.0 mg/L KT and 1.0 mg/L NAA had the best effect on PLB proliferation, 50-d PLB proliferation times reaching to 9.52. Certain concentrations of PE and AE could promote PLB differentiation, and 100 g/L PE brought well-grown seedling in test tube and the highest differentiation rate, being up to 92.6% . Conclusion The optimal hormone matching and additives concentration on proliferation and differentiation of PLB of Dendrobium officinale Kimura et Migo have been obtained, which can lay a foundation for its rapid propagation and artificial seed preparation.

Objective·To investigate the incidence, risk factors and treatment of the catheter-related thrombosis (CRT) in breast cancer patients after implantation of totally implantable venous access port (TIVAP) in chemotherapy. Methods·A total of 190 cases after implantation of TIVAP were investigated. Color Doppler ultrasound was used to monitor the neck blood vessels to find whether there was CRT before chemotherapy and before taking out the port. The incidence of CRT, occurrence time, risk factors and treatment efficacy were observed. Results·There were 112 (58.9%) cases with CRT and 108 (56.8%) patients with asymptomatic thrombosis, and only 4 cases had symptomatic thrombosis, the incidence of which was 2.1%. Most thrombosis developed on the 21th day after catheterization, and the patients over the age of 60, with clinical stage Ⅲ - Ⅳ and chemotherapy regimens TEC (docetaxel combined pirubicin and cyclophosphamide) were the risk factors for thrombosis. All the patients with asymptomatic thrombosis accepted anticoagulant treatment with low molecular heparin, earthworms enzyme or aspirin, respectively, but there was no significant difference in efficacy in the three groups (P=0.743). Conclusion·Port catheter related symptomatic thrombosis incidence is low but the incidence of symptomatic thrombosis is high in the breast cancer patients after chemotherapy. Age, tumor stage and TEC chemotherapy regimens are the risk factors for catheter-related thrombosis.

Objective To detect the changes of interleukin-18 (IL-18) in plasma of trauma patients and evaluate their value in early warning of organ dysfunction. Methods A prospective study was carried out in 54 trauma patients admitted in from March 2001 to September 2002, which were divided into low injury severity score(ISS) group (Group L-ISS) and high ISS group (Group H-ISS). ELISA was applied to measure the level of IL-18 of blood samples that were collected on arrival, at days 4, 7 and 14 following admission. In the meantime, IL-18 level of plasma samples from patients with systemic inflammatory response syndrome (SIRS), sepsis and multiorgan dysfunction syndrome (MODS) was retrospectively analyzed so as to calculate the critical value of IL-18 in predicting organ dysfunction. Results After trauma, IL-18 concentration of plasma reached peak at days 4 and 7, and decreased gradually at day 14, which was significantly related to SIRS, sepsis and MODS, respectively. The IL-18 level was high relatively in plasma from patients with organ dysfunction. The higher IL-18 level in plasma within seven days after trauma indicated the severer organ dysfunction. Conclusion IL-18 is sensitive in early warning of organ dysfunction after trauma.
