Objective To investigate the therapeutic effect of Tiaozhi Decoction for the treatment of coronary heart disease induced stable angina complicated with hyperlipemia, and to observe its effect on serum inflammatory factors. Results One hundred qualified patients were evenly randomized into treatment group and control group. Both groups were given conventional western medical treatment with reference to Guide for Diagnosis and Treatment of Chronic Stable Angina, and additionally, the control group was given oral use of Simvastatin and the treatment group was given Tiaozhi Decoction orally. The treatment of the two groups covered 8 weeks. Before and after treatment, blood lipid levels of total cholesterol ( TC) , triglyceride ( TG) , low-density lipoprotein cholesterol ( LDL-C) , high- density lipoprotein cholesterol ( HDL-C) , apolipoprotein A (ApoA) and apolipoprotein B (ApoB) were observed. The frequency of angina pectoris attack and the dosage of Nitroglycerin Tablets per week in both groups were recorded during the treatment. Therapeutic effect on lowering blood lipid and on improving electrocardiogram was evaluated after treatment. Serum levels of hypersensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), homocysteic acid (Hcy), adiponectin (APN), and oxidized low-density lipoprotein (ox-LDL) were detected before and after treatment. Results(1) The results of Ridit analysis showed that the treatment group had better therapeutic effect on lowering blood lipid and on improving electrocardiogram than the control group ( P<0.05) . ( 2) After treatment, TG, HDL-C, ApoB and ApoA levels were much improved in the treatment group compared with those in the control group (P<0.01) . ( 3) The frequency of angina pectoris attack and the dosage of Nitroglycerin Tablets per week were reduced in the treatment group compared with those in the control group (P<0.01) . (4) After treatment, the treatment group had lower hs-CRP, IL-6, Hcy and ox-LDL levels, and higher APN level than the control group (P<0.01) . Conclusion Tiaozhi Decoction is effective for the treatment of coronary heart disease induced stable angina complicated with hyperlipemia through improving lipid metabolism and reducing angina pectoris attack, and the mechanism may be related with the regulation of inflammatory factors.

OBJECTIVE: To investigate the preventive and therapeutic effects and the possible mechanisms of Dilingdan Decoction (DLDD), a compound Chinese herbal medicine, on rats with renal tubulointerstitial fibrosis induced by unilateral ureteral obstruction (UUO). METHODS: Sixty SD rats were randomly divided into sham-operated group, untreated group, enalapril-treated group and DLDD-treated group. Blood urea nitrogen (BUN), serum creatinine (SCr), urine protein quantization in 24 hours and pathological changes of the obstructed kidney were observed. The expressions of transforming growth factor-beta1 (TGF-beta1), alpha-smooth muscle actin (alpha-SMA), fibronectin (FN) and laminin (LN) were detected by immunohistochemical method and colored-multimedia pathological image analysis system. RESULTS: Massive inflammatory infiltrates and collagen expression in renal interstitial in the untreated group were observed on the 7th day. Compared with the sham-operated group, percentages of area of TGF-beta1, alpha-SMA, FN and LN expressions in the untreated group were markedly increased (P<0.05), while the percentage of area of interstitial fibrosis was decreased in the DLDD-treated group as compared with the untreated group (P<0.05). On the 14th day, the percentages of area of TGF-beta1, alpha-SMA, FN and LN expressions were declined in two treated groups as compared with the untreated group (P<0.05), but had no statistical difference in biochemical indicators, including BUN, SCr and 24-hour urinary protein. On the 21st day, the level of SCr and the percentage of area of TGF-beta1 expression in the DLDD-treated group were lower than those of the enalapril-treated group (P<0.05). CONCLUSION: DLDD can reduce the excretion of urinary protein and the degree of interstitial fibrosis, and significantly inhibit the expressions of TGF-beta1, alpha-SMA, FN and LN. DLDD is superior to enalapril in protecting renal function after long-time application in rats.

BACKGROUND: The main reason for the postoperative loosening of cemented prosthesis is interfacial debonding and bone cement internal damage. Most studies have suggested that both of them occur in the process of fatigue damage, however, little is reported on primary loading that results in the initial damage to the bone cement-stem interface and inside of bone cement. OBJECTIVE: To study the mechanical properties of bone cement-stem interface, and the effect of crack formation in bone cement on interfacial loosening. METHODS: The cement-titanium al oy handle implant components were prepared. The maximum adhesive force of bone cement-stem interface was measured using push-in experiment. The cement damage and crack in the process of bone cement-handle interfacial debonding were monitored online using acoustic emission tester. The non-destructive testing on the metal surface and the inner layer of bone cement cylinder was conducted using three-dimensional surface profiler, ultrasonic microscopy and X-ray detector. RESULTS AND CONCLUSION: The online monitoring results of debonding experiment and acoustic emission tester demonstrated that the initial damage of bone cement initiated in the primary loading of patients after operation, rather than at fatigue damage stage. Bone cement coffin caused cracks initiation mainly due to the combination effect of radial and axial stress. The bone cement-stem interfacial shear lag effect could not prevent the gradual extension of interface and inner coffin crack from top to bottom. The bone cement defects formed in solidification process was likely to affect the mechanical properties of the material, and eventual y induced the crystal face and macromolecular chain fractures, forming silver striated cracks and leading component failure.

Objective Calcified epithelioma is a rare benign tumor in head and face. It is seldomly seen canceration. But it has local invasion behavior. The aim of this study was to explore the methodology in the diagnosis and treatment of calcified epithelioma in head and face, and to improve the accuracy of clinical diagnosis. Methods A retrospective analysis was carried out in 26 patients with calcified epithelioma in head and face. Results 53. 8 % patients with calcified epithelioma were less than 13-year-old. The disease was easily misdiagnozed. In this group of patients the misdiagnosis rate reached to 42. 3 %. Btype ultrasonographic diagnosis possessed a high level of concordance with histological diagnosis. There were three major types of calcified epithelioma: type 1, a mass with internal echoic foci; type 2, a hyperechoic mass with high beam; type 3, no calcification in the parenchyma. Piomatricoma was described as a skin tumour histologically composed of shadowcells, basophillic cells, foreign body giant cells and intracellular and stromal calcification. The treatment was excision and no recurrences were found by followup. Conclusions It is important for clinicians to know the clinical features of calcified epithelioma. Imaging studies including ultrasonography would help establish the diagnosis. Surgical excision with clear margins is recommended for this tumor.

BACKGROUND: It has been verified in the experiments over the past that the self-prepared Chinese herb, fuzhisan can retard natural aging in rats, suggesting that such drug acts on anti-aging.OBJECTIVE: To observe the effect of optimum effective concentration of nerve cell cultured with fuzhisan on morphological alternation of neuroblastoma SH-SY5Y cell.DESIGN: Repeated measurement.MATERIALS: The experiment was performed in Beijing Key Laboratory Room of Cerebral Aging of Xuanwu Hospital Affiliated to Capital University of Medical Sciences from June 2002 to April 2003. Self-prepared Chinese herb, fuzhisan [composed of 6 herbs, such as shichangbu (Rhizoma Acori Graminei), yuanzhi (Radix Polygalae), etc.] was co-developed by Prof.Wang De-shen from Department of Neurology of First Clinical Medical College of Harbin Medical University and Prof. Xu Xiao-yun from Department of Neurology of Shanghai Oriental Hospital. In addition, amyloid βprotein 25-35 segment and SH-SY5Y neuroblastoma were provided.METHODS: Fuzhisan of various concentrations were used for incubation of neuroblastoma SH-SY5Y cell. Thiazolyl blue (MTT), colorimetric method was used to determine the cell survival rate. Dose-effect relationship curve was drawn up to search optimum drug concentration. The cells cultured with 6-pore plate were divided into normal control, amyloid β-protein 25-35 25 μmol/L group, amyloid β-protein 25-35 25 μmol/L + fuzhisan 45×10-3 g/L groups and fuzhisan 45×10-3 g/L group. They were incubated for 24 hours to observe cell morphological alternation and determine neurosome area and axon length.ery group.length of every group: Those in amyloid β-protein 25-35 25 μmol/L group were decreased remarkably than the normal control [(505.5 ±122.36),(599.8 ±141.25) μm2; (26.0±13.97), (36.5 ±15.58) μm, (t =3.903,3.447, P=0.000)]. Those in fuzhisan 45×10-3g/L group and amyloid β-protein 25-35 25 μmol/L + fuzhisan 45×10-3 g/L group were increased remarkably than amyloid β-protein 25-35 25 μmol/L group [(918.3±178.34),(896.6 ±257.14), (505.5 ±122.36) μm2; (96.8 ±43.31), (88.3 ±30.23),(26.0±13.97) μm, (t=10.922, 14.172, P=-0.000)].CONCLUSION: With injury of amyloid β-protein 25-35, fuzhisan still enhances the survival of cultured nerve cell, manifested as promoting the increase of neurosome area and axonal extension.

BACKGROUND: Amyloid β(Aβ) protein is the core of senile plaque.Being the toxic segment of Aβ, Aβ25-35 has been extensively applied in the experiments of recent years. The research in the past has verified that the self-prepared Chinese herb, fuzhisan can promote the survival of the cultured neural cells and probably acts on the treatment of Alzheimer disease (AD).OBJECTIVE: To study the resistance of fuzhisan to Aβ25-35 toxicity to cultured neural cells and the probable approaches.DESIGN: Repeated measurement based on the cells.SETTING: Department of neurology of a university hospital and key experimental room in brain aging in a university hospital.MATERIALS: The experiment was performed in Beijing Key Experimental Room in Brain Aging of Xuanwu Hospital from June 2002 to April 2003. Dopaminergic SH-SY5Y cell of neuroblastoma and Aβ25-35 were employed. Chinese herb, fuzhisan was decocted with mild fire and its upper clear solution was collected and prepared into storage solution at the concentration of 0. 5 g/mL. Antibody: Beijing Key Experimental Room in Brain Aging of Xuanwu Hospital prepared cAMP responsive element binding protein(CREB),Bcl-2 in B lymphatic leukaemia-2 genetic product and cytochrome C(CytC).METHODS: SH-SY5Y cell was incubated with Aβ25-35 of various doses alone or in combination with fuzhisan and was compared with blank control. MTF metabolic rate of cultured neural cells were determined under different incubation conditions. Western-blot method was used to measure the protein expression changes in incubation with fuzhisanalone, incubation with Aβ25-35 alone and the combination incubation, compared with the blank control.MAIN OUTCOME MEASURES: It was to study MTT metabolic rate in the comparison between each experimental group and the blank control and expressions of CREB, Bcl-2 and CytC relevant to survival/death of neural cells.RESULTS: Survival rate of SH-SY5Y cell was increased by 11.4% in incubation with fuzhisan alone. It was remarkably improved in incubation combining fu zhisan with Aβ25-35 as compared with Aβ25-35 alone. The expressions of CREB and Bcl-2 in Aβ25-35 group were decreased and were increased in fuzhisan group. CytC expression in cytoplasm was increased in Aβ25-35 group and was declined with fuzhisan incubation.CONCLUSION: Fuzhisan promotes the survival of cultured neural cells and its protection is still existed under Aβ25-35 injury. Fuzhisan brings such effects into play probably by the protein expressions relevant to survival/death of cells.
