ObjectiveTo investigate the outcomes of mother a nd baby smaller than 37 gestational age caused by preeclampsia. Method sThe data for 122 preterm birth that was single pregnancy with preecla mpsia in our hospital from January 1993 to December 2002 were collected. The pri nciple of diagnosis and treatment, the outcomes were analyzed retrospectively. T he 122 pregnant women were divided into 3 groups according to their gestational age, more than 28 weeks and smaller than 31 +6 weeks was the first group (28 cases), more than 32 weeks and smaller than 33 +6 weeks was the second grou p (26 cases), more than 34 weeks and smaller than 36 +6 weeks was the thir d group (68 cases). The data were statisted with SAS software.Results The earlier the pregnancy-induced hypertension happened, the earlier the preeclampsia occured, the mean time was 14 03 d, 16 85 d,22 22 d, respect ively, (P0.05), the outcomes of mothers were good. Increasing the gestational age under the cond ition that the occurrene of comptications was not increased, 60 64% pregnant wo men accepted the treatment of improving the maturity of fetal lung. There were n o differences among the three groups at the morbidity of perinatal SGA, intracra nial hemorrhage (P 0.05) .ConclusionWe could improve the outcomes of pret erm birth caused by preeclampsia by enhancing the perinatal care, treating and t erminating pregnancy activey Increasing the gestational age, improving the matur ity of fetal lung would decrease the morbidity of severe RDS and improve the pe rinatal outcome effectively.

AIM:To investigate the effects of tanshinone IIA ( Tan) on cardiac action potential in rats with a-cute cerebral ischemia (ACI).METHODS:ACI was established in rats accordingly .Animals were divided into 3 groups:sham group, ACI group, and ACI with Tan treatment group .The defect of neural function in each group was graded , elec-trocardiogram was measured , monophasic action potential was recorded , and the levels of cardiac troponin I ( cTnI ) and creatine kinase-MB ( CK-MB) were examined by commercially available kits .RESULTS:Compared with ACI group , Tan significantly decreased the scores of the defect of neural function , reduced the incidence and duration of the abnormalities in electrocardiogram , prolonged the effective refractory period , action potential duration at 50%repolarization and action po-tential duration at 90%repolarization, and inhibited the elevation of cTnI and CK-MB levels.CONCLUSION:Tan main-tains a stable heart rhythm in ACI rats , which may be related to its protective effect on ischemic myocardium .

OBJECTIVE:To discuss the research and clinical application of drug eluting stents,in addition,to explore the effects of drug eluting stents on preventing and curing coronary restenosis. METHODS:The databases of Medline and Chinese CNKI were retrieved using computer from 1993 and 2009,and the literature was selected according to inclusion and exclusion criteria. The rapamycin eluting stent and paclitaxel eluting stent were widely used in preventing and curing in stent restenosis,the problems existed in this process were discussed. RESULTS:Drug eluting stents could prevent in stent restenosis following stent implantation,however,the problems such as poor adherence or stent fracture still occurred in clinic. CONCLUSION:Drug eluting stents exhibit efficiency and safety in preventing restenosis,but there still existed problems need to further explore.

Objective: To observe the effect of the combinative supplementation of Formoterol, Indomethacin and Roxithromycin on cancer cachexia (CC) and to study the mechanism. Methods: Male BALB/c mice bearing colon 26 adenocarcinoma for 9 days were served as models of cancer cachexia. The mice were divided into nine groups. Physiological conditions, body weight and food intake were documented every day. Serum levels of cytokine and nutritional markers were detected 7 days after treatment. Results: Tumor-bearing caused a wasting of non-tumor body weight and gastrocnemius muscle. Serum tumor necrosis factor-α, (TNF-α) and interleukin-6 (IL-6) levels were significantly elevated accompanied with nutrition depletion in tumor-bearing mice. After treatment with combinative supplementation of Formoterol, Indomethacin and Roxithromycin, left gastrocnemius weight and serum glucose were improved and the levels of TNF-α and triglyceride were down-regulated. Conclusion: Formoterol, Indomethacin and Roxithromycin had their own positive effects to CC mice. Drugs combinationin in tumor-bearing mice with cancer cachexia could produce synergistic action.

Objective:To compare the clinical and imaging characteristics between central nervous system vasculitis(CNSV)and mitochondrial encephalomyopathy(ME),so as to analyze the differential diagnosis of the two disorders.Methods:Clinical data on seven patients with CNSV and five with ME were retrospectively analyzed.The clinical manifestations,laboratory parameters,imaging features and histological characteristics were compared to screen for the evidence of their differential diagnosis.Results:The MRI results of both CNSV patients and ME patients(MELAS type)showed a multi-lesion pattern.The symptoms of CNSV patients included headache,limbs weakness,and erythrocyte sedimentation rate(ESR)increase.The symptoms of MELAS patients included epilepsy and increased serum lactic acid.The electroencephalographic manifestations of both diseases were abnormal:CNSV patients mainly had diffused lesions accompanied with limited alterations;ME patients had evidence of epileptic discharge,which was consistent with the clinical symptoms.Conclusion:Clinical manifestations of CNSV and ME patients are more valuable than imaging findings in the diagnosis of the two diseases.CNSV is characterized by vascular disorders and inflammatory reactions;ME is characterized by abnormal energy metabolism and severe damage of gray matter.The final diagnosis should depend on laboratory and histological examinations.

Objective To evaluate the clinical effectiveness of rotatory hinge prosthesis replacement for treatment of giant cell tumors around knee joint. Methods Thirty-one patients with giant cell tumors of bone around the knee from January 2001 to January 2008 in our hospital were reviewed. There were 13 males and 18 females. Their ages ranged from 19 to 56 and the mean age was 33.5. The anatomic site for the lesions were the distal femur (20 cases) and proximal tibia (11 cases). Using Companacci’s staging system: 7 patients were classified as grade Ⅱ and 24 as grade Ⅲ. The patients were grouped as follows: the tumor breaking through the cortex with an extraosseous mass in 2 patients,having pathologic fracture in 3,representing more biologically-aggressive lesions in 5,and having one or more local recurrences in 21. All patients had been treated with en block excision and reconstruction with rotatory hinge prosthesis. Results According to the follow-up for 12 to 96 months,all patients had no local recurrence or metastasis. The mean Musculoskeletal Tumor Society (MSTS) score was 24.0?2.5,with an excellent limb function in 23 patients,good in 6 patients,and fair in 2 patients. The overall excellent and good function was obtained in 93.5% of the patients. Conclusion Rotatory hinge prosthesis replacement is an effective method to treat giant cell tumors of bone around the knee joint. It also can reduce the local recurrence and obtain better the outcomes.
