Twenty-two patients with hyperthyroid caxdiopathy(HTC),38 patients with hyperthyroid (HT),and 10 healthy controls were tested for plasma levels of brain natriuretic peptide(BNP).The findings showed that BNP level in HTC group(433±141)μg/L was significantly higher than that in HT group(110±38)μg/L and healthy control group(10±3)μg/L(both P<0.01);HT group vs healthy control group,P<0.01).After 3 months'treatment for HT,BNP decreased significantly.The patients with higher BNP levels had an increased incidence of HTC.Plasma BNP test might be useful in predicting the prognosis and the treatment efficacy in patients with HT.

OBJECTIVETo compare the differences of clinical effects in female patients with obesity and hyperlipidemia of yang deficiency of spleen and kidney syndrome between warm acupuncture combined with auricular acupuncture and simple warm acupuncture.

METHODSOne hundred and thirty patients were randomly divided into an observation group and a control group, 65 cases in each one. In the control group, acupuncture was used at Pishu (BL 20), Zhongwan(CV 12), Shenshu(BL 23), Zhongji(CV 3), Guanyuan(CV 4), Mingmen(GV 4), Taibai(SP 3), Fenglong(ST 40), etc.; warm acupuncture was applied at Pishu(BL 20), Zhongwan(CV 12), Shenshu(BL 23) and Zhongji(CV 3); the treatment was required once every two days and for 3 months continuously. In the observation group, based on the treatment in the control group, thumbtack intradermal needles were embedded at auricular points, including pi(CO13), shen(CO10), pangguang(CO9), sanjiao(CO17), neifenmi(CO18), neishengzhiqi(TF2), etc. Obesity indices [body mass(W), obesity degree(A), body mass index(BMI), body fat percentage(F%)] blood lipid indices [serum total cholesterol(TC), triglyceride(TG), low density lipoprotein(LDL-C), high density lipoprotein(HDL-C)] and clinical efficacy were observed before and after treatment in the two groups. Results After treatment in the two groups, the obesity indices of W, A, BMI, F% and the blood lipid levels of TC, TG, LDL-C were obviously decreased compared with those before treatment (all P<0. 01) and the HDL-C levels were apparently increased than those before treatment (both P<0. 01). After treatment, the improvement of TC and HDL-C in the observation group was superior to that in the control group (both P<0. 01). The difference was not statistically significant in the aspect of improving every obesity index between two groups (all P>. 05). The comprehensive total effective rate of the observation group was 95.4% (62/65), which was better than 84. 6% (55/65) of the control group (P<0. 001).

CONCLUSIONWarm acupuncture combined with auricular acupuncture and simple warm acupuncture can both benignly adjust abnormal lipid metabolism of obesity patients with hyperlipidemia, and warm acupuncture combined with auricular acupuncture are superior to simple warm acupuncture treatment on antiobesity action and improving the TC and HDL-C levels.

Objective To investigate the effects of down-regulation of Netrin-1 expression on cell proliferation,apoptosis and migration of a cutaneous squamous cell carcinoma(CSCC)cell line SCL-1.Methods Unspecific(control)small interference RNA(siRNA)and Netrin-1-targeting siRNA were designed and constructed.SCL-1 cells were divided into 3 groups to remain untreated(control group 1),be transfected with control siRNA(control group 2)and Netrin-l-targeting siRNA(experiment group)by using Lipofectamine 2000 respectively.After 48 hours of additional culture,flow cytometry was performed to detect the apoptosis of cells,Western blot to determine the protein expression of caspase-3 and-9,Netrin-1 and matrix metalloproteinases (MMP)in these cells,and Boyden chamber was utilized to evaluate the migration of cells.Enzyme linked immunosorbent assay(ELISA)was performed with cholecystokinin-8(CCK-8)kit to estimate the proliferation of cells at 24,48,72 and 96 hours after the transfection.Results The expression of Netrin-1 protein was significantly downregulated in SCL-1 cells in the experiment group compared with the control group 1 and 2 (0.207 ± 0.044 vs.0.741 ± 0.111 and 0.716 ± 0.109,F =31.43,P ＜ 0.05).The Netrin-1-targeting siRNA significantly downregulated the proliferation of SCL-1 cells,but induced the apoptosis in SCL-1 cells with significant differences in the percentage of early apoptotic cells and late apoptotic cells between the control group 1,2 and experiment group(11.74 ± 0.33 vs.11.55 ± 1.22 vs.24.74 ± 2.43,F=68.63,P＜ 0.01;3.82 ± 0.32 vs.4.69 ± 0.68 vs.5.33 ± 0.18,F =8.58,P ＜ 0.05).The experiment group showed a significant increase in the expression of caspase-3 and-9(1.458 ± 0.111 vs.0.398 ± 0.057 and 0.412 ± 0.049,F =183.99,P ＜ 0.01;0.967 ± 0.099 vs.0.234 ± 0.036 and 0.205 ± 0.033,F =138.11,P ＜ 0.01),but a statistical decrease in the expression of MMP-2(0.235 ± 0.038 vs.0.862 ± 0.040 and 0.892 ± 0.035,F =291.07,P ＜ 0.01)compared with the control group 1 and 2.Conclusions The down-regulation of Netrin-1 expression can suppress the proliferation and migration of SCL-1 cells,but promote the apoptosis in SCL-1 cells.

BACKGROUND:Current research data have shown that patients with epilepsy are often accompanied by complications such as cognitive impairment. Recent studies have demonstrated that melatonin has an inhibitory effect on epilepsy, but its underlying mechanism is unknown. OBJECTIVE: To investigate the effects of melatonin on the cognitive function and GluR2 expression in the hippocampus of rat models of epilepsy, and further study the mechanism of melatonin against epilepsy. METHODS: Rat models of chronic epilepsy were established by intraperitoneal injection of lithium chloride-pilocarpine, and intraperitonealy injected with sufficient amount of physiological saline and melatonin respectively. Control group was set for observation. RESULTS AND CONCLUSION:At 4 and 6 weeks after modeling, the GluR2 expression level in the hippocampus of rats in the epilepsy + melatonin group was significantly higher than that in the epilepsy group (P < 0.05); the GluR2 expression level in the synaptic membrane of hippocampal CA1 region of rats in the control and epilepsy + melatonin groups was significantly higher than that in the epilepsy group (P < 0.05). At 4 days after modeling, compared with epilepsy group and epilepsy + physiological saline group, the escape latency, operation time, active avoidance latency, passive avoidance latency of rats in the epilepsy + melatonin group were significantly decreased (P< 0.05), the correct rate and active avoidance number were significantly increased (P < 0.05). These results demonstrate that melatonin can improve the cognitive function of rat models of epilepsy by up-regulating the expression of GluR2 in the synaptic membrane of hippocampal CA1 region.

OBJECTIVE: To investigate the salidroside on proliferation and apoptosis of human hepatocellular carcinoma HepG2 cells and its possible mechanisms of anti-tumor. METHODS: Cultured HepG2 cells in vitro were used as the research object and their cell morphology were observed by inverted microscope. The inhibitory rate of cell proliferation was measured by MTS assay. The cell apoptosis was determined by flow cytometry. The protein expressions of Bcl-2, Bax, caspase-3 and caspase-8 were detected by Western blot analysis. RESULTS: Salidroside could inhibit the proliferation of HepG2 cells and promote its apoptosis. The Bax, caspase-3 and caspase-8 protein expression were increased while Bcl-2 protein expression was decreased in HepG2 cells in a concentration-dependent manner. CONCLUSION: Salidroside can inhibit the proliferation and induce the apoptosis of HepG2 cells, and the mechanism may be associated with regulating protein expression of Bcl-2, Bax, caspase-3 and caspase-8.

Objective　To investigate the effect of type II dengue virus infection on the survival rate of Aedes albopictus, to provide basic data for the prevention and control of dengue fever. Methods　The Aedes albopictus C6/36 cells were cultured to amplify and harvest type Ⅱ dengue virus. After emergence, the lab-domesticated Aedes albopictus was fed daily with freshly prepared 10% glucose water under 28℃ and humidity ≥70%, and used for infection experiment at 3-5 days of age. The day before infection, male mosquitoes were selected out, and the female mosquitoes were divided into infected and uninfected groups, deprived of food and water. When infected, they respectively were fed blood meals containing or without dengue virus typeⅡ(the blood meal of the uninfected group was the same as the infected group's, minus the presence of TypeⅡ dengue virus), and the saturated blood mosquitoes were fed with 10% glucose water. The survival of mosquitoes in two groups was observed and recorded daily. On the 14th day after blood feeding, the nucleic acid of dengue virus typeⅡof Aedes albopictus was detected by fluorescence quantitative PCR, and the infection rate was calculated. The survival rates of infected and uninfected Aedes albopictus were calculated and compared. The survival curves of the two groups were plotted using survival analysis and the log-rank test was performed. Results　A total of 99 infected saturated blood Aedes albopictus were reared in the infected group, and 83 in the uninfected group. By the 14th day after infection, 31 and 15 mosquitoes had died in the infected and uninfected groups respectively, with mortality rates of 31.31% (31/99) and 18.07% (15/83), respectively, indicating a higher mortality rate in the infected group. The log-rank test showed that the survival curve of the infected group of Aedes albopictus was lower than that of the uninfected group (χ2=4.121 9, P<0.05). The infection rate of Aedes albopictus detected by fluorescence quantitative PCR was 77.94% (53/68). Conclusion　TypeⅡdengue virus infection can reduce the survival rate of Aedes albopictus.

Abstract: To investigate the factors affecting lean non-alcoholic fatty liver disease (NAFLD), so as to provide the reference for the prevention and treatment of lean NAFLD. Methods: Individuals who underwent physical examination at Huzhou Central Hospital from January 1, 2023 to March 31, 2024 and had a body mass index (BMI) <23 kg/m2 was selected. Demographic information, lifestyle behaviors, dietary habits and physical examination data were collected through questionnaire surveys. Lean NAFLD was assessed using abdominal ultrasonography combined with BMI. Factors affecting lean NAFLD were analyzed by using a multivariable logistic regression model. Results: A total of 627 individuals were surveyed, with a mean BMI of (20.83±2.01) kg/m2. There were 349 males (55.66%) and 278 females (44.34%). Lean NAFLD was detected in 74 cases, with a detection rate of 11.80%. Multivariable logistic regression analysis identified BMI (OR=1.830, 95%CI: 1.165-2.869), gender (male, OR=2.615, 95%CI: 1.402-4.875), triglycerides (OR=3.062, 95%CI: 1.613-5.812), alanine aminotransferase (OR=1.587, 95%CI: 1.106-2.277), vegetable and fruit intake (150-300 g/d, OR=0.416, 95%CI: 0.230-0.752; >300 g/d, OR=0.303, 95%CI: 0.141-0.649), dairy product intake (≥300 mL/d, OR=0.369, 95%CI: 0.195-0.701) and sugared beverage intake (1-250 mL/d, OR=1.601, 95%CI: 1.071-2.393; >250 mL/d, OR=2.438, 95%CI: 1.363-4.354) as factors affecting lean NAFLD. Conclusion The risk of lean NAFLD is associated with BMI, gender, triglyceride, alanine aminotransferase, and the vegetable and fruit, dairy product and sugared beverage intake.

Objective:To investigate the effect of genistein,a soybean-derived isoflavone,on thestimulating effect on bone resorption of IL-1?.Methods:The osteoclasts(OCs)were isolated with themethods of Yu Shifeng.The rat calvaria were cultured as an organ.The cells in the experiment weregrown in four respectively:Control(without genistein or IL-1?),10~(-6) mol/L genistein,10 ?g/L IL-1?and 10~(-6) mol/L genistein+10 ?g/L IL-1?.The area of bone resorption,the concentration of Ca~(2+) in thesupernatant liquid of OCs cultures and mice calvaria were tested.The contents of acid phosphatase(ACP)were also examined by biochemistry method.The index of bone resorption was counted as the ra-tio of the experiment average and control ones,which indicated the increase in bone resorption when itwas above 1.0.Results:The area of bone resorption of 10~(-6) mol/L genistein+10 ?g/L IL-1? increasedcompared with that of 10~(-6) mol/L genistein,while the concentration of Ca~(2+) in the supernatant liquid ofOCs cultures decreased significantly.The index of bone resorption of 10~(-6) mol/L genistein+10 ?g/L IL-1? lied between 10~(-6) mol/L genistein and 10 ?g/L IL-1?.In the organ culture,there was no differencein the content of ACP among all the groups,The index of bone resorption of 10~(-6) mol/L genistein+10?g/L IL-1? was below that of 10?g/L IL-1?,but both were above 1.0.The index of bone resorptionwas below 1.0 in the group of 10~(-6) mol/L genistein.Conclusion:Genistein can suppress obviously thebone resorption simulated by single IL-1?.
