Objective To investigate the effects of total flavonoids of Herba Epimedii(HEF)on the metabolism of typeⅠcollagen and the expression of cathepsin K in the bone of ovariectomized(OVX)rats. Methods Fifty-four female SD rats were allocated into 6 groups;OVX group,sham operation group,OVX rats followed by three doses of HEF(40,80 and 160 mg?kg~(-1)?d~(-1))and nilestriol(0.1 mg?kg~(-1)?d~(-1))for 12 weeks respectively.Bone mineral density(BMD)of whole body was determined by dual-energy X-ray absoptiometry.The level of cross-linked N-telopeptide of typeⅠcollagen(NTx)in the urine were determined by ELISA.The amounts of typeⅠcollagen protein and cathepsin K protein in bone tissue were detected by immunohistochemical method and Western blotting.Results Compared with OVX group,the total BMD values in the HEF treated groups were increased(all P＜0.05),and the expression levels of typeⅠcollagen in three HEF treated groups rose significantly in a dose-dependent manner after 12 week,and simultaneously,both the expression of cathepsin K in bone and the level of NTx/Cr were reduced markedly(P＜0.05),being most significant(P＜0.01)in the group treated with the highest dose of HEF(160 mg?kg~(-1)?d~(-1)).Conclusion HEF seems to be able to elevate BMD and improve bone quality of rats via promoting synthesis and inhibiting proteolysis and absorption of typeⅠcollagen in the bone.

Objective To investigate the relationship between β-fibrinogen (β-Fg) gene -455G/A,- 148C/T polymorphisms and atrial fibrillation (AF) with cerebral infarction.Methods Polymerase chain reaction-restriction fragment length polymorphism was used to detect the genotypes of -455G/A and -148C/T in 97 patients with AF with cerebral infarction (AF with cerebral infarction group),80 patients with AF alone (AF group),and 98 health subjects (healthy control group).Results The A allele frequencies of -455G/A in the AF with cerebral infarction group and the AF group were 0.304 and 0.344 respectively.They were significantly higher than 0.179 in the healthy control group (all P＜0.05).The T allele frequencies of - 148C/T in the AF with cerebral infarction group and the AF group were 0.348and 0.369,respectively.They were significant higher than 0.240 in the healthy control group (all P＜0.05).Conclusions The A allele of -455G/A and the T allele of -148C/T were associated with AF with cerebral infarction and AF.

Objective To assess the outcome of liver transplantation in patients over sixty years of age,in order to attempt to expand the indications of liver transplantation. Methods From August,2000 to January,2002, the clinical data of 36 patients who underwent liver transplantation in our department were analysed retrospectively. Of the 36 cases, the data (operating time, the length of hospitalization, rejection rate and ICU stay days after operation) of 5 patients whose age were ≥60 years (elderly group) and the data of 31 patients whose age were under 60 years (

ObjectiveTo explore the effect of community education and service of mental health on improvement of people's diathesis.Methods483 subjects from 6 social strata were investigated with the questionnaire to find out the community resident's idea on mental health and need for psychological service.ResultsThere were significant differences in the concepts of criteria of mental health among people in different social strata and ages (P<0.001),and requirements for community education and service of mental health varied from one to another. Forms and contents of community education and service were multiplicate.ConclusionThe community education and service of mental health should be developed widely for improving people's diathesis.

Objective:To investigate the common reasons,clinical features and the strategy of management with postoperative bleeding in thorax and abdominal cavity in orthotopic liver transplantation(OLT).Methods:Data based on the 12 cases undergoing OLT in our hospital from August 2000 to January 2002 were collected and analyzed.Results:The most common reason for bleeding post OLT was staxis in abdominal cavity(n=5),then was as followed:the abdominal bleeding caused by hepatic artery thrombolytic therapy(n=3),liver biopsy(n=2),Tipps(n=1),surgical technical reason(n=1).In all 12 cases,re operation of laparotomy was needed in 6 because of the massive bleeding.Acute renal failure happened in 5,and 3 needed hemodialysis.Four patients died postoperatively from massive abdominal bleeding,and 3 caused directly by the acute renal failure.Conclusion:Bleeding in the thorax and abdominal cavity happens frequently after OLT,and staxis in abdominal is the most common reason.The correct management for bleeding is the key thing to prevent complications.It is important to pay close attention to perioperative improvement of coagulative capacity,control of massive bleeding and prevention of renal failure.

Objective:To investigate the risk and prognosis of orthotopic liver transplantation (OLT)for patients with advanced hepatocellular carcinoma(HCC)and those without liver tumor.Methods:The risk and prognosis of 21 cases of orthotopic liver transplantation for patients with HCC were retrospectively reviewed and the comparison was made between such patients and 19 others with non tumor caused end stage failures whose OLT procedures have been done at the same period.Results:Compared with the non tumor OLT recipients,the HCC patients have a better preoperative coagulation function.In accordance with this,the blood lose,the required transfusion and the total infusion during the operation were also less than those of non tumor OLT patients.The duration of hypotension induced by bleeding in HCC patients were also shorter than that in non tumor patients.There were more patients in HCC group with uneventful postoperative course than that in non tumor group.The perioperative mortality was also lower in HCC group.Although the recurrence of malignance affected the long term survival of HCC patients,the whole survival rate was similar to that of non tumor OLT patients.Conclusion:OLT remains an effective alternative for the advanced HCC patients for whom there was no other better choice.It is possible that some patients can get a long term survival and are free of the recurrence of the HCC after OLT treatment.

OBJECTIVETo observe the therapeutic effect of Yiqi Yangyin principle (YQYY, the treating principle in TCM to supplement Qi and nourish Yin) on corticosteroid withdrawal in patients with systemic lupus erythematosus (SLE) in remission stage and its influence on some immune parameters.

METHODSThe SLE patients were divided into two groups, 30 in the treated group and 10 in the control group, who were treated by conventional method with corticosteroids and/or immunosuppressant in acute progressive stage, and YQYY was added to the treated group in remission stage.

RESULTSThe total effective rate was 93.3% in the treated group and 90.0% in the control group, comparison between the two groups showed significant difference by Ridit test (P < 0.05). The immune parameters, IgG and C3 were significantly improved after treatment in the treated group (P < 0.01), but changed insignificantly in the control group. The maintaining dose of prednisone used in the two groups was 7.08 +/- 5.26 mg/d and 11.72 +/- 6.48 mg/d respectively, the amount used in the treated group was significantly lower than that in the control.

CONCLUSIONUsing mainly YQYY Principle to treat SLE in remission stage could withdraw the corticosteroid smoothly, relieve symptoms and improve immune function.

OBJECTIVETo explore the value of dual-time-point (18)F-fluorodeoxyglucose integrated positron emission and computed tomography ((18)F-FDG PET-CT) in differentiation of malignant from benign gastrointestinal diseases.

METHODSSixty five patients with suspected gastrointestinal lesions underwent dual-time-point (18)F-FDG PET-CT imaging. Standardized uptake value (SUV) was calculated for semi-quantitative assessment. The SUV of the two acquisitions were signed SUV(early) and SUV(delayed), respectively. Then the change of SUVmax (ΔSUVmax) was calculated. The ROC curves of the SUV(early), SUV(delayed) and ΔSUV were drawn to find the best cut-off point value for differential diagnosis, and then the sensitivity, specificity, positive predictive value, negative predictive value and accuracy were calculated, respectively.

RESULTSOf the malignant lesions, the SUVmax in delayed imaging were significantly higher than those in early imaging, while there were no significant differences of SUVmax between the two images of the benign lesions. The ΔSUVmax of the malignant lesions were significantly higher than that of the benign ones. Taking the SUVmax higher than 9.2 in early imaging as positive diagnostic criteria, the sensitivity was 72.7%, the specificity was 85.7%, the positive predictive value was 91.4%, the negative predictive value was 60.0%, and the accuracy was 76.9%. Taking the SUVmax higher than 10.9 in delayed imaging as positive diagnostic criteria, the sensitivity was 75.0%, the specificity was 90.5%, the positive predictive value was 94.3%, the negative predictive value was 63.3%, and the accuracy was 80.0%. Taking the ΔSUVmax higher than 5.1% as positive diagnostic criteria, the sensitivity was 95.5%, the specificity was 85.7%, the positive predictive value was 93.3%, the negative predictive value was 90.0%, and the accuracy was 92.3%. The accuracy of dual-time-point (18)F-FDG PET-CT imaging was significantly higher than that of single-time point (18)F-FDG PET-CT imaging.

CONCLUSIONDual-time-point (18)F-FDG PET-CT imaging is a useful method for differentiating malignant from benign gastrointestinal diseases, and it is superior to the single-time point (18)F-FDG PET-CT imaging.

OBJECTIVETo investigate the usefulness of (18)F-FDG PET/CT imaging in restaging, evaluating the treatment outcome, monitoring relapse and predicting prognosis of T-cell lymphoma.

METHODSRetrospective analysis of PET/CT image results of thirty-four patients with T-cell lymphoma, and to evaluate its clinical significance in restaging, treatment efficiency, relapse monitor and prognosis prediction.

RESULTSClinical restaging among the 20 stage I and II patients, 6 were ascended, 9 descended and 5 unchanged. Restaging among the other 14 stage III and IV patients, 3 were ascended, 4 descended and 7 unchanged. There were 12 patients in complete remission (CR), 11 in partial remission (PR), 2 in stable disease (SD) and 9 in progressive disease (PD) among all the 34 patients. There is obvious statistical difference of the standardized uptake value (SUV) between the efficacy group and the inefficacy group after treatment of 6 courses at least in 25 patients among all the 34 patients (P = 0.009). There is obvious statistical difference of the SUV value before and after treatment in 8 patients among all the 34 patients (P = 0.000). There is obvious statistical difference in the survival time between the efficacy group and the inefficacy group after treatment of 6 courses at least in 25 patients among all the 34 patients (P = 0.015).

CONCLUSIONS(18)F-FDG PET/CT imaging plays an very important role in guiding clinical restaging, evaluating the treatment outcome, monitoring relapse and predicting prognosis of T-cell lymphoma. It is helpful to establish personalized treatment planning.
