BACKGROUND: Ovariectomized animals usually are employed for the study of women osteoporosis while little is known about theenergy balance of ovariectomized animals. Many previous studies showed that soy isoflavone could decrease the hyperlipemia resulted by high-fat feed, and how about the effect of soy isoflavone on the energy metabolism in ovariectomized animals?OBJECTIVE: To explore the pathologic effect of soy extract and its active components on the energy metabolism in ovariectomized rats so as to provide adequate evidences for the primary rehabilitation and prevention of type Ⅱ diabetes mellitus, disturbance of lipid metabolism as well as hypertension and coronary atherosclerotic heart disease.DESIGN: A randomized and controlled trial with the experimental animals as subjects.SETTING: Laboratory of Cell and Biochemistry in a university.MATERIALS: Ninety Wistar rats (SFP grade, license code: scxk11-00-006) were randomized into 9 groups: normal group, sham group,model group, estrogen group, high-dose soy flavone group, low-dose soy flavone group, high-dose soy extract group, low-dose soy extract group and soy polysaccharide group, with 10 rats in each group.INTERVENTION: Except the rats in normal group and sham group,the bilateral ovaries of other rats were all removed. From one week after operation, body weight and daily food intake were detected once a week.Six weeks later, the rats were killed to calculate the forage transformation efficiency, measure body length, work out the body mass index (BMI),and separate the abdominal fat and weight.MAIN OUTCOME MEASURES: ①Effect of soy extract on the abdominal fat accumulation of ovariectomized rats. ②Effect of soy extract on food intake of ovariectomized rats. ③Effect of soy extract on forage transformation efficiency of ovariectomized rats.RESULTS: After ovariectomy, the food intake, body weight and BMI all raised, and the forage transformation efficiency increased, with abdominal fat accumulation. The changes of energy metabolism induced by ovariectomy were all weakened at different degrees in estrogen group, soy extract group and soy flavone group, while no influenced was found in soy polysaccharide group.CONCLUSION: The ovariectomized rats can be used as animal model of the climacteric fat women. The soy extract, with the effective component of flavonoid, can reduce the pathologic changes such as the increase of food intake, body weight and forage transformation efficiency induced by ovariectomy.

Objective To determine the efficacy of berberine in the treatment of non-alcoholic steatohepatitis ( NASH) , and to investigate the regulating effect on macrophage phenotype transformation in hepatic tissue on methionine -choline deficiency (MCD) diet induced NASH mice.Methods Fourty male C57BL/6 mice were randomly divided into 4 groups (10 mice per group): the normal group (fed with normal diet), the NASH model group (fed with MCD diet), rosiglitazone treatment group (30mg/kg) and berberine treatment group (150mg/kg).Drugs were adopted in the preventive intervention method for 2 weeks.The hepatic histopathological method was adopted to evaluate the drug therapeutic effect.The serum levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-6, and IL-10 were examined with ELISA method.M1 and M2 phenotype were detected by flow cytometry .Results The results showed berberine improved the degree of hepatic histopathology .Berberine not only reduced the level of TNF-α, but also increased the level of IL-10 in serum on NASH mice significantly ( P <0.05 ) . Flow cytometry data indicated that berberine decreased M 1 type macrophages and increased M 2 type macrophages in liver tissue .The ratio of M1/M2 was significantly decreased in berberine and rosiglitazone treated group ( P <0.01 ) .Conclusion Berberine may improve the hepatic pathological process in MCD diet induced NASH model possibly through modulating macrophage phenotype transformation , i.e.The ratio of M2 type is more than M1 type in hepatic tissue , and increasing anti-inflammatory cytokines .

Objective: To investigate the characteristics of dead HIV/AIDS cases within 1 year after confirmatory testing in Jingzhou City, Hubei Province from 1996 to 2021, so as to provide the evidence for facilitating early identification and treatment of AIDS. Methods: The basic and follow-up data of HIV/AIDS cases were retrieved from the HIV/AIDS Comprehensive Response Information System of Chinese Disease Prevention and Control Information System, and mortality density and its trend were evaluated within 1 year after confirmatory testing. The factors affecting death within 1 year after confirmatory testing were identified using a Cox proportional hazards model, and the demographics, detection, treatment and cause of death were analyzed among dead HIV/AIDS cases within 1 year after confirmatory testing. Results: A total of 3 304 HIV/AIDS cases were included, with 508 deaths within 1 year after confirmatory testing. The overall mortality density was 17.43 per 100 person-years, and the mortality density appeared a tendency towards a reduction from 1996 to 2021 (χ2trend=21.053, P<0.001). Of all dead HIV/AIDS cases within 1 year after confirmatory testing, 77.76% were men, 67.72% at ages of 45 years and older, 83.86% with transmission by heterosexual contact, 83.66% identified in medical institutions, 62.20% without antiretroviral therapy, and 47.83% without detection of CD4+T cell count. Mortality that was not associated with AIDS was the predominant cause of death among dead HIV/AIDS cases within 1 year after confirmatory testing (58.86%). Age of 30 years and older (HR: 1.781-4.644, 95%CI: 1.073-7.784), identification in medical institutions (HR=2.130, 95%CI: 1.306-4.474), initial CD4+T cell count of <200 cells/μL (HR: 2.649-12.879, 95%CI: 1.669-19.189), no antiretroviral therapy (HR=7.945, 95%CI: 5.743-10.993) and initiation of antiretroviral therapy 4 to 12 months after confirmatory testing (HR=1.636, 95%CI: 1.005-2.662) resulted in a higher risk of mortality within 1 year after confirmatory testing. Conclusions The mortality density appeared a tendency towards a reduction among cases within 1 year after confirmatory testing in Jingzhou City from 1996 to 2021. Mortality within 1 year after confirmatory testing was associated with advanced age, heterosexual contact transmission, identification in medical institutions, low CD4+T cell counts, and delay or absence of antiretroviral therapy.

Objective To investigate the sleep structure of children with attention deficit hyperactivity disorder (ADHD) and the differences among subtypes of ADHD.Methods Ninety children with ADHD were diagnosed in Department of Neurology, the Children's Hospital Affiliated to Capital Institute of Pediatrics between June 2012 and June 2013, including 75 boys and 15 girls,6-14 years old [(9.5 ± 2.4) years old], and among them there were 55 cases of ADHD-combined type, 25 cases of ADHD-inattentive type, and 10 cases of ADHD-hyperactive impulsive type.Thirty healthy children whose age and sex matched with ADHD group,came from Beijing and the surrounding area,were selected as the healthy control group,including 23 boys and 7 girls,6-14 years old [(9.2 ± 2.9) years old].Two groups underwent full overnight sleep assessment.Results The latency of rapid eye movement(REM) in children with ADHD was (146.58 ± 47.28) minutes, and the sleep latency was 19.00 minutes [(8.25-37.50) minutes];while the latency of REM in healthy control group was (87.55-± 13.59) minutes, and the sleep latency was 9.00 minutes [(3.50-13.63)minutes].Compared with healthy control group, children with ADHD demonstrated the increased latency REM and sleep latency, and decreased sleep efficiency,the increasing times of awakening and total duration,and these differences were all statistically significant(all P ＜ 0.05).The percentage of non-rapid eye movement(NREM) phase Ⅱ in ADHD hybrid was lower than the ADHD attention-deficit(t =2.012,P ＜ 0.05).Sleep latency in ADHD attention-deficit was longer than the ADHD hybrid(t =2.964,P ＜ 0.05).No statistical differences were found among the various types in other indicators.The prevalence of periodic limb movements in sleep(PLMS) was 27.78％ (25/90 cases) in ADHD group and the prevalence of PLMS was 3.30％ (1/30 cases) in the healthy control group.The differences in prevalence between 2 groups were statistically significant (x2 =8.053, P ＜ 0.05).Conclusions Children with ADHD significantly display more problems with sleep.Sleep latency and NREM Ⅱ are different between ADHD attention-deficit and ADHD hybrid.

Objective To explore the value of Artis zeego robot imaging system endoscopic retrograde cholangiopancreatography (ERCP) for biliary calculi. Methods ERCP was performed on 12 patients with biliary tract dilation, diagnosed by B ultrasonography. Artis zeego robot was used simultaneously to acquire 3D images and biliary system reconstruction. The diagnostic consistency was assessed based on endoscopy and surgery if necessary. Results 3D rotating acquisition and biliary reconstruction were performed in the 12 patients. All diagnosis coincided with those of surgery and ERCP findings, achieving a consistency rate of 100%. Patients with extrahepatic bile duct stones of uncertain number (n = 2), with suspected biliary duct calculi ( n = 1 ) and with suspected intrahepatic bile duct stones ( n = 2) under ERCP were all diagnosed by the robot imaging system. Conclusion During ERCP, 3D rotating image acquisition and biliary reconstruction with Artis zeego robot is helpful for precise diagnosis of biliary tract stones.

OBJECTIVE: The purpose of this research was mainly two-fold: first, to get an understanding of current researches conducted on Alzheimer disease in China; second, to systematically evaluate and compare Alzheimer's treatment delivered by traditional Chinese medicine (TCM) and Western medicine. METHODS: Two steps were employed in this research. They were data collection and cleaning, followed by systemic review and qualitative analysis. The data were selected from the following two databases: CNKI (http://www.cnki.net) and Wanfang Data (http://www.wanfangdata.com.cn). Inclusion criteria were: (1) Chinese literature; (2) Published between year 1994 and year 2004; (3) Using TCM as treatment and Western medicine as control; (4) Similar research purposes and methodology; (5) Subjects were diagnosed as Alzheimer disease. Descriptive analysis, homogeneity test, meta analysis, sensitivity analysis and subgroup analysis were performed in the second step. RESULTS: Supposing all qualified studies were of high quality, we got the following conclusion: the advantage of TCM was losing because of the newly-developed acetylcholinesterase inhibitors came in market. Moreover, the studies conducted after year 2002 were more homogeneous in comparison with those conducted in early years. Those studies using mini-mental status examination (MMSE) as outcome measurement were also more homogeneous than non-MMSE measurement groups. Combined odds ratio in comparative studies was 1.5 fold higher than that in experimental studies. Regarding to different outcome measurement, those studies using TCM assessment profile were 2.58(4.79/1.86) fold higher than those using MMSE as outcome measurement. CONCLUSIONS: After systemic literature search, we found that only 40 out of 2,403 studies met our inclusion criteria. Moreover, those qualified studies were of low quality. Therefore, the external validity of this study would be compromised. The solution to this would be to improve study quality by strengthening study design and carefully select more homogeneous subjects in terms of syndrome differentiation, by so doing, the results of meta analysis will be more convincing and easily recognized by international society.

BACKGROUND: Because of the specificity and complexity of hepatic portal, carcinoma of bile duct of the hepatic portal is a difficulty in the surgical treatment. OBJECTIVE: To evaluate the safety and feasibility of simultaneous pancreaticoduodenectomy and liver transplantation for the end-stage hilar cholangiocarcinoma. RESULTS AND CONCLUSION: Pathology demonstrated a middle or low differentiation of hilar cholangiocarcinoma, and left, right hepatic duct, together with lobus quadratus were invaded. The tumor metastasized to hilar and posterior pancreatic lymphonodes, without involving the head of pancreas, duodenum and stomach. The function of transplanted liver recovered smoothly, and the endocrine and exocrine functions of pancreas were kept well. CA19-9 dropped to the normal levels. The patient recovered and discharged at 1 month after surgery, and still survived after one year follow up. These suggest that simultaneous pancreaticoduodenectomy and liver transplantation as a treatment of hilar cholangiocarcinoma are safe and feasible.

Aim To investigate the effect of curcumin against high-fat-diet induced C57BL/6J mice bone changes and the correlation between the expression of cathepsin K and curcumin.Methods Curcumin treated C57BL/6J mice had been on high fat diet for 12 weeks.The HE, Alizarin red S staining and Safranin O/fast green staining of femur were employed to evaluate bone microstructure, bone metabolism and bone development.The expressions of cathepsin K were assessed by Western blot and immunohistochemical staining.Results Histopathological results showed that curcumin could improve the destruction of trabecular bone structure, cartilage development and bone calcification.Biomechanical results proved that curcumin could improve the bone strength of the type 2 diabetic mice induced by high fat.The results of immunohistochemistry and Western blot assay indicated that curcumin could significantly inhibit the expression of cathepsin K in bone tissues of mice.Conclusion Curcumin can increase bone strength, improve bone microstructure, and enhance the degree of bone calcification, which may be achieved by inhibiting the expression of cathepsin K.
