Objective:To investigate the interaction between non-alcoholic fatty liver disease (NAFLD) and overweight/obesity on the risk of mild cognitive impairment (MCI) in elderly individuals.Methods:This cross-sectional study was based on the Hubei Memory and Aging Cohort Study (HMACS). Cluster random sampling was used to select 5 661 elderly individuals aged≥65 years in Wuhan from 2018 to 2023. Standardized neuropsychological assessments and clinical examinations results were collected. The NAFLD was diagnosed by abdominal ultrasound. The logistic regression analysis was used to analyze the association of NAFLD and overweight/obesity with MCI. The impacts of interaction between NAFLD and overweight/obesity on the risk of MCI were analyzed using both multiplicative and additive models.Results:Among the 5 661 elderly individuals included in the analysis, 2 563 were male and 3 098 were female, with a mean age of (72.24±5.51) years. A total of 2 239 participants (39.6%) resided in rural areas, 2 841 (50.2%) were overweight/obesity, 2 390 (42.2%) had NAFLD, and 1 694 (29.9%) were diagnosed with MCI. The risk of MCI in elderly individuals with NAFLD and overweight/obesity was 2.975 times ( OR=2.975, 95% CI: 2.489-3.557, P<0.001) of that in non-overweight/obese individuals without NAFLD. There was a multiplicative interaction between NAFLD and overweight/obesity on MCI ( OR=1.508, 95% CI: 1.169-1.944, P=0.002). NAFLD and overweight/obesity had an additive interaction effect on the risk of MCI, and the relative excess risk of interaction, attributable proportion of interaction and the synergy index was 1.099 (95% CI: 0.630-1.593), 0.369 (95% CI: 0.222-0.487), 2.256 (95% CI: 1.457-3.492), respectively. Conclusion:There is an interaction between NAFLD and overweight/obesity in elderly individuals, and the co-existence of NAFLD and overweight/obesity increases the risk of MCI in this population.

Osteoarthritis is a chronic,degenerative joint disease characterized by destruction of articular cartilage,osteophyte formation and narrowing of the joint space,which seriously affects the life quality of patients.However,the pathogenesis of osteoarthritis is still not clear.Kashin-Beck disease (KBD) is an endemic,chronic and deformative osteoarthropathy that mainly occurs in children aged 5-15 years old.The etiology and pathogenesis of KBD are still unclear.Wnt/β-catenin signaling pathway is involved in the development of embryonic cartilage and maintaining the stability of adult bones,which is a key pathway regulating the growth,development and differentiation of chondrocytes.Therefore,the authors review the progress of Wnt/β-catenin signaling pathway in the pathogenesis of osteoarthritis or KBD.

Objective To explore the significance and correlation between MCP-1 and cardiovascular complication of diabetes. Methods 65 patients with diabetes and 64 patents with IGT and 60 healthy persons as control group are chosen from a population of 1231residents at Jiangnan community in Guangzhou city. Ultrasonic inspection of carotid artery was applied to the intimae media thickness (IMT),and the levels of-MCP-1 were detected by Elisa. Result There was significant difference in the levels of MCP-1 among the normal control group, IGT group and DM group (P=0.000).The levels of MCP-1 in IGT complicated with AS patients were significantly higher than that in IGT alone patients. The levels of MCP-1 in DM complicated with AS patients were significantly higher than that in DM alone patients. The levels of MCP-1 were positively correlated with IMT in these patients. A forward LR Logistic regression analysis showed that IMT was a dependent variable, gender, MCP-1 and age are independently correlated with IMT. Conclusion MCP-1 is correlated with diabetes and its cardiovascular complication and it may be served as the target of therapy.

BACKGROUND: Left ventricular hypertrophy (LVH) is an important ring-joint of congestive heart failure (CHF). It is also considered to be independent risk factor of cardiovascular disease, so how to reverse or relieve LVH is valuable to cure CHF.OBJECTIVE: To observe the effect of Lujiao prescription on degree of LVH in patients with CHF.DESIGN: A random-control observation on CHF patients.SETTING: Department of Cardiovasology, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine.PARTICIPANTS: A total of 20 patients with CHF were selected from the Special Clinic and Department of Cardiovasology in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from January 1996 to December 1998. All of them were consistent with the Framirham diagnostic criteria and following standardizations: ①above Ⅲ degree of cardiac functional grading by New York Heart Association (NYHA);②over 3 months case history;③accepted basic treatment of quantity sufficient diuretic and vasodilating agent excluding angiotensin converting enzyme inhibitor (ACEI);LVH was proved by echocardiogram or chest X-ray. They were informed of treatment items and consented.METHODS: According to random lot, the patients were divided into Lujiao prescription group and Digoxin group, each containing 10 patients.①Oral administrations of Lujiao prescription (35 mL, two times per day, produced by Shanghai Shuguang Hospital) and Digoxin (0.125-0.25 mg per tablet, batch number: 970757, once daily) were given in the corresponding groups, and the treatment duration was 3 months. After treatment, all the patients were detected in①NYHA cardiac functional grading; ②interventricular septal thickness (IVST) and posterior wall thickness (PWT) in diastolic phase through echocardiogram, myocardium weight of left ventricular by Devereux formula, left ventricular mass index (LVMI) corrected by bodysurface area, and degree of LVH;③the level of plasma angiotensin Ⅱ (Ang Ⅱ ) by radioactive immunoassay.MAIN OUTCOME MEASURES: NYHA cardiac functional grading, e-chocardiogram (IVST, PWT, LVMI, degree of LVH), the level of plasma Ang Ⅱ.RFSULTS: All 20 adopted patients entered the result analysis.①The classification of NYHA cardiac functional grading ( Ⅰ , Ⅱ ,Ⅲ,Ⅳ) were respectively 2, 5, 3, 0 case in Lujiao prescription group and 2, 4, 4, 0 case in Digoxin group after treatment, and difference was significant compared with those before treatment (0, 0, 7, 3, P ＜ 0.05).②IVST, PWT and LVMI of Lujiao prescription group were obviously decreased after treatment [(11.20±0.42), (12.10±0.32) mm, P ＜ 0.01; (10.60±0.84), (11.40±1.10) mm,P ＜ 0.01; (139.4±12.4), (155.3±15.4) g/m2, P ＜ 0.01], while those of the Digoxin group were untouched (P ＞ 0.05). The degree of LVH of Lujiao prescription group after treatment was obviously decreased [normal, mild,moderate, sever: 2, 6, 2, 0; 0, 3, 4, 3, P ＜ 0.01], while that of the Digoxin group was not obviously decreased (P ＞ 0.05).③)The level of plasma Ang Ⅱin the Lujiao prescription group was obviously decreased [(97.7±19.5),(144.0±18.5) ng/L, P ＜ 0.01], while that of the Digoxin group was not obviously increased (P ＞ 0.05).CONCLUSION: Lujiao prescription can reverse or relieve the degree of LVH in patients with CHF.

BACKGROUND: Congestive heart failure (CHF) is the clinical syndrome of all kinds of heart disease on the serious or final stage. About half of patients with organic heart disease will have heart failure that has a high incidence rate and mortality. The survival of heart failure was inferior to that of malignant tumor.OBJECTIVE: To confirm the clinical effect of Lujiao prescription on CHF and elucidate its possible mechanism.DESIGN: A control observation on CHF patients.SETTING: Department of Cardiovasology, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine.PARTICIPANTS: A total of 60 patients with CHF were selected from the department of cardiovasology in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from January 1996 to December 1998. There were 31 male and 29 female. Included criteria: ①All of patients were consistent with Framinham diagnostic criteria. ② Above Ⅲ degree by New York Heart Association(NYHA). ③ Three months case history. ④Accept quantity sufficient diuretic and vasodilating agent (exclude angiotensin converting enzyme inhibitor ). ⑤ Left ventricle hypertrophy was proved by echocardiogram or chest X-ray. ⑥ Differentiation of symptoms and signs of Traditional Chinese Medicine refers to asthenia syndrome of differentiation of symptoms and signs of Traditional Chinese Medicine (1986, Researching Association of Chinese integrated medicine) General state of health and basic disease of the patients in the two groups were not significant deviation.METHODS: 60 patient s of CHF were randomly divided into Lujiao prescription group(n=40) and Digoxin group (n=20) at the rate of 2:1. Lujiao prescription group: Orally liquid decoction of Lujiao Prescription 35 mL (1 mL contain crude drug 1.6 g) Bid. po. Course of treatment: 4 weeks. Digoxin group: Digoxin tablet, 0.125-0.25 mg, qd. po. course of treatment: 4 weeks.After 4-week treatment, the patients' clinical effect, integrals of the symptoms of renal deficiency, classification of function capacity of the NYHA,Lee's heart failure score, heart rate(HR), myocardium oxygen consumption (MOC), proportion of heart to chest, echocardiogram, measurement of plasma angitention Ⅱ (Ang Ⅱ ) and plasma atrial natriuretic factor (ANF) were observed.MAIN OUTCOME MEASURES: ① The total clinic effective rate. ②Integrals of the symptoms of renal deficiency. ③ Classification of function capacity of the NYHA. ④ Lee's heart failure score. ⑤HR and MOC. ⑥The proportion of heart to chest. ⑦ Ejection fraction(EF), cardic output (CO), interventricular septal thickness (IVST), posterior wall thickness (PWT) and left ventricular mass index (LVMI) through echocardiogram. ⑧The measurement of plasma Ang Ⅱ and plasma ANF.RESULTS:Totauy 60 patients entered the final analysis. ① The total clinical effective rate of the Lujiao prescription group was 90 %, which showed no significant difference from the Digoxin group (90 %, P ＞ 0.05).② Improvement was significantly observed in the integrals of the symptom of renal deficiency of the patients in the Lujiao prescription group after treatment (P ＜ 0.01), but which was not significant in the Digoxin group(P＞ 0.05). ③ It was found that classification of functional capacity of NYHA between Lujiao prescription group and Digoxin group after treatment was obviously decreased (P ＜ 0.01). ④ Lee's heart failure score of patients in Lujiao prescription group and Digoxin group after treatment was decreased (P ＜ 0.01). ⑤Myocardium oxygen consumption and HR of the patients in the Lujiao prescription group and Digoxin group after treatment was decreased (P ＜ 0.01). ⑥ The proportion of heart to chest between Lujiao prescription group and Digoxin group after treatment was decreased (P ＜ 0.01).⑦ EF and CO were increased by Lujiao prescription and by Digoxin (P＜ 0.01,vs pretreatment, respectively). IVST, PWT, LVMI of Lujiao prescription group after treatment were obviously decreased (P ＜ 0.01), while those of the Digoxin group were not obviously decreased (P ＞ 0.05). ⑧ Thlevel of plasma Ang Ⅱ of the patients in the Lujiao prescription group after treatment were obviously decreased (P ＜ 0.01), while that of the Digoxin group were not obviously decreased (P ＞ 0.05). The level of plasma ANF was decreased by Lujiao prescription and by digoxin(P ＜ 0.01, vs pretreatment, respectively).CONCLUSION: There is increasing cardiac constriction power and regressing left ventricular hypertrophy of patients with CHF by Lujiao prescription. The therapeutical effect of Lujiao prescription for CHF is better than that of Digoxin. The effect may be related to the regulation of circular or local endocrine(plasma Ang Ⅱ and ANF) disorder.

BACKGROUND: Pressure overload can lead to the activation of reninangiotensin-aldosterone system, and then left ventricular remodeling occurs.Captopril can reverse this progress.OBJECTIVE: To observe the effect of captopril in reversing left ventricular remodeling in rats with pressure overload and to elucidate its possible mechanism.DESIGN: A randomized controlled trial.SETTING: Department of Integrated Traditional Chinese Medicine and Western Medicine, Nanjing General Hospital () Nanjing Military Area Command of Chinese PLA; Shuguang Hospital affiliated to Shanghai University of Traditional Chinese Medicine; Postdoctor Institute of Hebei Medical University.MATERIALS: The experiment was conducted in the Laboratory of Shanghai University of Traditional Chinese Medicine between January 1998 and October 1998. Totally 153 male Wistar rats were recruited.There were 5 experiments, 36 rats in each experiment except 9 rats in the fourth one.METHODS: A total of 36 Wistar male rats selected for each experiment were randomly divided into sham operation group, model group and captopril group. Rats in model group received modeling for 4 weeks, then gastric perfusion with 15 mL/kg of distilled water once per day for 4 consecutive weeks. Abdominal aorta of the rats in sham-operation group were separated without closure by sliver clip, then 4 weeks later the procedure was the same as that in model group. In captopril group, 4 weeks after modeling, the rats were performed gastric perfusion with diluted captopril of 100 mg/kg, once a day for 4 consecutive weeks.MAIN OUTCOME MEASURES: The effect of captopril on left ventricular mass index (LVMI), mRNA expression of collagen type Ⅰ and Ⅲ, content of plasma angiotensin Ⅱ (Ang Ⅱ ) and left ventricular tissue Ang Ⅱ,plasma atrial natriuretic factor (ANF), and serum aldosterone (ALD) level.RESULTS: Totally 153 rats entered the result analysis. During the test for detecting the absorbance (A) of collagen type Ⅰ, 3 rats in sham operation group and 3 in captopril group died, and 1 rat died in model group; finally 29 rats were involved. During the test for detecting the absorbance (A) of collagen type Ⅲ, 3 rats died in sham operation group, 4 rats diedin model group, and 2 rats died in captopril group; finally 27 rats were involved. All in sham operation group and captopril group was lower than that in model group [(2.24±0.12)/1 000, (2.67±0.40)/1 000, (3.15±0.47)/1 000, t=2.649,cantly lower in sham operation group and captopril group than in model group [(0.57±0.19, 0.86±0.25, 2.79±2.00), t=3.661, 3.170, P ＜ 0.01, 0.05].operation group and captopril group than in model group [(0.48±0.10,sion of mRNA of collagen type Ⅰ: It was significantly lower in sham operation group and captopril group than in model group [(79.1 ±18.6)%,plasma Ang Ⅱ content: It was significantly lower in sham-operation group and captopril group than in model group [(130.2±30.2),(137.6±39.5),was significantly lower in sham operation group and captopril group than in model group [(170.6±51.6), (202.5±64.2), (339.3±115.4) μg/L, t=4.623,P ＜ 0.01].type Ⅲ and mRNA expression in rats with pressure overload, suggesting its captopril on left ventricular remodeling might be related to decreasing circulating or local Ang Ⅱ level, plasma ANF and serum aldosterone as well as affecting the expression of collagen type Ⅰ and type Ⅲ mRNA.

To investigate the effect of Cornu Cervi Oral Liquid (mainly composed of Cornu Cervi, Fructus Psoraleae, Herba Epimedii, Fructus Corni, Fructus Ligustri Lucidi and Lignum Aquilariae Resinatum) in reversing myocardial fibrosis in rats with congestive heart failure caused by pressure overload and to explore its mechanism. Thirty six male Wistar rats were randomly allocated to mimic operation group (Group A), model group (Group B) and Cornu Cervi Oral Liquid group (Group C). Rat models of congestive heart failure were induced by constriction of abdominal aorta. Left ventricular mass index(LVMI) was observed; contents of collagen type Ⅰ and Ⅲ in left ventricular cardiac muscle were detected by immunohistochemical method and their mRNA expression by RT PCR; and plasma levels of angiotensin Ⅱ (AngⅡ), atrial natriuretic factor (ANF) and serum aldosterone (ALD) level were measured by radioimmunoassay method. LVMI, contents of collagen type Ⅰ and Ⅲ and their mRNA expression, levels of plasma and myocardial AngⅡ, plasma ANF and serum ALD were higher in Group B than those in Group A (P0 05).[Conclusion]Cornu Cervi Oral Liquid is effective in reversing myocardial fibrosis in rats with congestive heart failure caused by pressure overload and its mechanism may be related to the decrease of contents of collagen type Ⅰ and Ⅲ and their mRNA expression, levels of plasma and myocardial AngⅡ, plasma ANF and serum ALD.
