ObjectiveTo study the diagnostic value of serum type IV collagen(IV-C) in hepatic fibrosis. MethodsSerum IV-C levels were detected by using radioimmunoassay(RIA) and were compared with serum type Ⅲ procollagen(PCⅢ ) levels in normal controls(NC) and patients with chronic liver diseases. ResultsSerum IV-C and PCⅢ levels in patients with chronic liver diseases were all much higher than those in NC(P < 0.01, totally). Serum IV-C level in severe chronic hepa titis(CH) group was significantly higher than those in mild and median CH groups (P<0.01 total ly), and that in active liver cirrhosis(LC) group was significantly higher than that in static LC group (P＜0.05). There were significant positive correlation between serum IV-C level and serum PcⅢ level both in CH group and in LC group ( in CH γ=0.7023, in LC γ=0. 5878, P＜0. 001).Conclusion Serum IV-C level could reflect the activity of hepatic fibrogenesis.

A total of 17 hip joint lesion patients (24 hips) combined with ankylosing spondylitis and severe osteoporosis from March 1996 to March 2003.They.received autologous impaction bone graft and cementless total hip replacement.They were 20-52 years old,averagely 35 years.Harris score and X-ray method were used to evaluate clinical outcomes.A total of 17 patients (24 hips) were followed up for 36-120 months,averagely 87 months.Harris score increased from averagely 34 points (preoperation) to averagely 86.4 points (postoperation),resulting in an excellent and good rate of 87.5%.Radiograph showed that femoral prosthesis was closely fixed to proximal segment of the femur,without prosthetic infection or dislocation.One hip suffered from 5-mm prosthetic subsidence within 1 year following replacement,and no further subsidence following over 5-year follow up.The prosthesis showed good contact to sclerotin,without loose.It is suggested that bone mass has great effects on cementtess prosthetic replacement.Autologous impaction bone graft for bone remodeling provides a good method for total hip replacement in patients combined with ankylosing spondylitis and severe osteoporosis.The clinical outcome is satisfactory.

To investigate the correlation between cerebral infarction and carotid atherosclerosis.Methods:Bilateral carotid atherosclerotic plaques,intima-media thickness (IMT),and stiffness coefficient (β) in 60 patients with cerebral infarction were detected by high-frequency color Doppler imaging,and they were compared with the control group (n=60).Results:The detection rate of plaque in the cerebral infarction group was significantly higher than that in the control group (90% vs 28%,P<0.005); the constituent ratio of soft plaques in the cerebral infarction group was significantly higher than that in the control group (P <0.01),and the constituent ratio of flat and hard plaques was significantly lower than that in the control group (P<0.005); IMT and β values in the cerebral infarction group were significantly higher than those in the control group (P<0.01).Furthermore,IMT had significant positive correlation with β values (P<0.01).Conclusions:Carotid atherosclerosis is closely correlated with cerebral infarction.

AIM: To observe the effect of thichosanthes injection on the expression of proliferating cell nuclear antigen (PCNA) of vascular smooth muscle cell (SMC). METHODS: The expression of PCNA of cultured rabbit aortic SMC was examined with LSAB immunohistochemical technique, and [ 3H]-thymidine([ 3H]-TdR) incorporation data of SMC and the contents of superoxide dismutase (SOD), lipid peroxide (LPO), prostacyclin (PGI 2) and cyclic AMP (cAMP) in medium were simultaneously determined. RESULTS: Thichosanthes injection has an effects of increasing SOD activity, decreasing LPO, elevating PGI 2 and cAMP, reducing [ 3H]-TdR incorporation and expression of PCNA (all P

Objective To evaluate the value of color Doppler flow imaging(CDFI) in the diagonosis of placental site trophoblastic tumor(PSTT). Methods After being examined by transvaginal CDFI, four of six patients underwent curettage and two of them had hysterectomy and attached by chemical treatment. All the patients were verified to have a PSTT by pathology. Results The image of PSTT in CDFI included different size at different site, low resistence index (RI) of vessel around the lesion, and absence of vessel in the lesion. Conclusions The characteristic image in CDFI is helpful to the diagnosis of PSTT.

Subclavian artery occlusion is a common peripheral artery occlusion disease of various causes,with incidence of 1.9％.The most common symptoms are dizziness,ataxia,and hemiplegia that are caused by subclavian steal syndrome.Surgery is the only therapeutic method for symptomatic patients.Open surgery remains an important role despite of the rapid progress in endovascular surgery.Main surgical method includes carotid-subclavian transposition (CST),carotid-subclavian bypass (CSB) and axillary-axillary bypass.Each one is suitable for different lesions and anatomies.Both the effectiveness and safety have been testified.

Breast cancer is one of reproduction-endocrine related tumors, so the risk factors including environmental and genetic factors which can disrupt anabolism and function of estradiol may increase the risk of breast cancer. Persistent environmental endocrine disruptor chemical (EDCs) can disrupt anabolism and function of endogenous hormone and the degree of disruption may depend on genetic polymorphism. EDCs and metabolic enzyme genetic polymorphism were discussed in this paper. To study the risk factors of breast cancer, both of the environmental factors and the genetic factors should be included.

Non-invasive coronary artery angiography is one of the hotspots of imaging.This article reviewed the status and the relevant advancement of the cardiac EBCT, DSCT, MSCT and MR imaging.

A protein was isolated by DEAE-cellulose Chromatography and ultracentrifuge from the fruits of Momordica charantid L., and identified by chemical and polyacrylamide gel electrophoresis methods. The molecular weight was 34 000; isoelectric point pH 8.4,N-end amino acid was leucine.It was composed of 17 kinds of amino acids. The protein has been shown to have antifertility action in male rats.

Objective To establish culture method for Phyllanthus urinaria. Methods To study the possible effective factors of culture condition by comparing with different explants,sucrose,plant growth substance,and its ratio. Results The inductivity of stem was the highest about 55.56%,but callus of leaves could not be induced.6-BA was the most important factor on callus induction,followed by 2,4-D NAA and sucrose. Conclusion The optimal medium to induce and subculture is MS+2,4-D 0.5 mg/L+6-BA 1.0 mg/L+NAA 0.1 mg/L+sucrose 10 g/L.
