AIM: This study aimed at investigating the effects and mechanism of total alkaloids from Rhizoma Coptidis (TA) on ethanol-induced gastric mucosal injury in rats. METHODS: The experimental gastric damages were established by intragastric ethanol, and the protective effects of TA were evaluated by calculating lesion indices contents and superoxide dismutase (SOD) activity from rat gastric mucosa were measured to explore the interrelation between therapeutic effects of TA and these factors. The expressions of neuronal nitrogen monoxide synthase (nNOS), endothelial NOS (eNOS), and inducible NOS (iNOS)from ethanol-damaged gastric mucosa in rats were analysised using immunohistochemical method. RESULTS: TA significantly inhibited the gastric injury induced by ethanol ,in dose-dependent manner,and the effect of TA was superior to that of Berberine (Ber). TA obviously antric mucosa. TA significantly suppressed ethanol-induced decreasing nNOS and eNOS expression and elevation of iNOS expression in rat gastric mucosa. CONCLUSION: Rhizoma Coptidis is a potent candidate in therapeutic drugs of human alcohol-induced gastric injury. Its anti-injury effects involve in Ber and other ingredients of TA. The protective mechanisms of TA involve in inhibiting generation of oxygen-derived free radical, accelerating scavenging of free radicals, relieving lipid peroxidation, and maintaining NO content in normal level by inhibiting decreasing of nNOS and eNOS expression and elevation of iNOS expression.

Aim To investigate effects of Icariin in rats with acute myocardial ischemia induced by isoproterenol(ISO).Methods Icariin(12,6,3 mg?kg-1) was administrated through iv pathway for five days.Myocardial ischemia model of rats was induced by subcutaneous injection(sc) of ISO(30 mg?kg-1 for two days,once a day).The change of Electrocardiogram(ECG) was observed.The levels of lactate dehydrogenase (LDH),superoxide dismutase(SOD), malondialdehyde(MDA) and nitric oxide(NO)in serum were measured.Cardiac indexes(HW/BW and LVW/BW)and cardiac infarction area(IS/V%)were examined.Results Compared with the model group,Icariin(12,6,3 mg?kg-1) could effectively reverse the evident change of T wave and J point induced by isoproterenol,notably decrease the levels of LDH and MDA in the serum, distinctly increase the levels of SOD and NO in the serum(P

Objective To investigate the influence of host animals on epidemics of hemorrhagic fever with renal syndrome (HFRS) so as to provide a basis for effective control of HFRS.Methods From the national infectious disease network direct reporting system,the incidence of HFRS cases diagnosed by direct diagnosis of medical institutions in Qingdao was collected from 2011-2015.We captured rats indoor and outdoor by night trapping method quarterly and calculated the capture rates from 2011-2015 in Qingdao areas.The incidence of HFRS in different regions and the change of seasonal growth,the distribution of host animals,the characteristics and distribution of animals,and the seasonal variation of dominant species were analyzed and a database was set up and statistic analysis was conducted by SPSS 13.0.Results The peak incidence rate of HFRS in Qingdao areas occurred in 2012 (3.54/100 000) and presented a decrease trend year by year (x2 =64.15,P ＜ 0.05),but there were different characteristics among the epidemic areas,and lowest in 2015 (1.68/100 000).And the peak presented a two-peak pattern which was mainly an autumn peak and a gentle peak in late spring and early summer.The epidemics were gradually decreased from the rural areas to the urban fringes and then the urban areas.The seasonal variation was disappeared gradually.There was a heavy epidemic intensity in areas with a high capture rate and a complex type of host animals.The epidemic peak was in consistence with the distribution of rats.Capture rates were different among the epidemic areas.The capture rate in Jiaonan was the highest [5.32％(2 886/54 287)] and lowest in Pingdu [1.77％ (258/14 584)].The mean (x2 =820.39,P ＜ 0.05) and annual capture rates (x22011-2015 =32.61,356.24,233.07,129.33,33.42,all P ＜ 0.05) among epidemic areas were different.In the third quarter the accumulated capture rate was the highest [4.69％ (1 187/25 301)].In total 8 kinds of host animals were captured and the dominant species were brown rat [30.27％ (1 235/4 080)],house mouse[29.75％ (1 214/4 080)] and striped field mouse [16.25％ (663/4 080)].Conclusions The epidemic intensity of HFRS is related to the densities and the types of host animals.The gradually decreased epidemic pattern from the rural areas to the urban fringes and then the urban areas may be related to urbanization and improved health behaviors.

Background The pathogenic mechanism of thyroid associated ophthalmopathy (TAO) is still unclear,which is considered to be an autoimmune disease.It is confirmed that interleukin-17A (IL-17A) plays an important role in the occurrence and development of many autoimmune diseases.It is unclear that whether IL-17A participates in the pathogenesis of TAO.Objective This study was to explore whether IL-17A secreted by coculture system of peripheral blood mononuclear cells (PBMCs) and orbital fibroblasts (OFs) participates in the pathogenesis of TAO and its possible mechanism.Methods Periphery blood and orbital connective tissue were obtained from 12 patients with TAO and 8 patients who received prosthesis implantation for eyeball atrophy in Xiangya Hospital during April to December 2014.PBMCs were isolated by density gradient centrifugation,and OFs were cultured by explant culture method.The purity of T leukomonocyte in PBMCs was tested by flow cytometry,and OFs were identified by Giemsa staining and immunochemistry.OFs and PMBCs were incubated into 96-well plate in a 1:20 proportion to establish co-culture system.Different concentrations of phytagglutinin (PHA) (0,1.0,2.5,5.0,10.0 μg/ml) was added for 72 hours,and IL-6,IL-17A levels in the co-culture system supernatant and IL-17A receptor (IL-17RA) of the total cell membranes in the co-culture system were assayed by ELISA.The differences of IL-6,IL-17A,IL-17RA levels in co-culture system were compared between the TAO group and control group.Results The mean purity of T leukomonocyte in PBMCs was (81.10±0.21)％ in the TAO group and (80.05 ±0.38)％ in the control group respectively,with no significant difference between them(t =0.923,P＞0.05).Cultured OFs showed the positive response for Vimentin expression and Giemsa staining.After stimulated by 1.0 μg/ml PHA,the proliferation of both PBMCs and OFs were increased in the co-culture system.Apoptosis exist in PBMCs and the number of OFs decreased when PHA was higher than 1.0 μg/ml.The growth of PBMCs and OFs was faster in the TAO group than that in the control group in the same concentration of PHA.The contents of IL-6,IL-17A and IL-17RA in co-culture system were significantly different among various concentrations of PHA subgroups (IL-6:Fgroup =12.561,P=0.000;F ion =23.356,P =0.001.IL-17A:Fgroup =12.037,P =0.000;Fconcentration =19.206,P=0.000.IL-17RA:Fgroup =16.216,P=0.000;Fconcentraction =4.627,P=0.018).The production of IL-6,IL-17A and IL-17RA reached peak in both TAO group and the control group after 1.0 μg/ml PHA stimulated.However,the concentrations of IL-6,IL-17A and IL-17RA reduced with the increase of PHA concentration.The concentrations of IL-6,IL-17A and IL-17RA in co-culture system were significantly higher in the TAO group than those in the control group under the stimulation of the same concentration of PHA (all at P＜0.05).Conclusions The co-culture system of PBMCs and OFs stimulated with PHA can be the imitation of TAO pathogenesis in vitro,and PHA can amplify its immune reaction to imitate TAO pathogenic processes intuitively.The IL-6,IL-17A and IL-17RA secreted by PBMCs and induced by PHA are increased in TAO patients,implying that IL-17A participates in the pathogenesis of TAO through magnifying cellular immune response and inflammatory reaction.

OBJECTIVETo observe the protective effect of active fractions of Huanglian Jiedu Decoction (HJD) on primary cortical neuron injury after oxygen-glucose deprivation (OGD)/reperfusion (R) injury. Methods Using macroporous resin method, HJDFE30, HJDFE50, HJDFE75, and HJDFE95 with 30%, 50%, 75%, and 95% alcohol were respectively prepared. Then the content of active components in different HJD fractions was determined with reverse phase high-performance liquid chromatography (RP-HPLC). The OGD/R injury model was induced by sodium dithionite on primary cortical neurons in neonate rats. MTT assay was used to observe the effect of four fractions (HJDFE30, HJDFE50, HJDFE75, and HJDFE95) and seven index components of HJD on the neuron viability.

RESULTSRP-HPLC showed active component(s) contained in HJDFE30 was geniposide; baicalin, palmatine, berberine, and wogonside contained in HJDFE50; baicalin, berberine, baicalein, and wogonin contained in HJDFE75. The neuron viability was decreased after OGD for 20 min and reperfusion for 1 h, (P <0. 01), and significantly increased after administered with HJD, HJDFE30, HJDFE50, and HJDFE75 (P <0. 05, P <0. 01). Geniposide, baicalin, baicalein, palmatine, wogonside, and wogonin could increase the cortical neuron viability (P <0. 05, P <0. 01).

CONCLUSIONSHJDFE30, HJDFE50, and HJDFE75, as active fractions of HJD, had protective effect on primary cortical neuron injury after OGD/R. Furthermore, geniposide, baicalin, and baicalein were main active components of HJD.

Objective To develop Z-score reference ranges for mitral valve-tricuspid valve distance (MTD) in normal fetuses from the measurements of femur length (FL),biparietal diameter (BPD) or gestational age (GA) using fetal echocardiography.Methods A retrospective cross-sectional study of 1216singleton normal fetuses was performed.The gestation age ranged from 20 to 40 weeks.Non-cardiac fetal biometric parameters included FL and BPD and GA based on menstrual age.MTD was measured in a standard apical four-chamber view.Normal Z-score ranges were developed for MTD using GA,BPD and FL as independent variables.These were accomplished by using first standard regression analysis and then weighted regression of absolute residual values for each parameter in order to adjust for inconstant variance.Results Linear regression model was the best description of the data in each case and correlations between MTD and independent variables (FL,BPD,GA) were excellent.The linear regression equations between MTD and FL,BPD,GA were:Y =0.04629 × FL-0.02868 (r =0.827) ; Y =0.04018 × BPD-0.08293(r =0.767) ; Y =0.0098 × GA-0.07075 (r =0.721),respectively.Heteroscedasticity of standard deviation(SD) with increasing independent variables also could be modeled with a simple linear regression.Linear regression equations between SD of MTD and FL,BPD,GA were:Y =0.0149 × FL-0.0095 (r =0.9947),Y =0.0126 × BPD-0.02793 (r =0.9931),Y =0.00305 × GA-0.021 (r =0.991),respectively.According to these equations,MTD Z-score =(the actual measurement of MTD-predicted MTD)/prediction SD.Conclusions Normal reference ranges and Z-scores for MTD have been provided.These normative data may be useful tools for assessment of fetal MTD,especially has potential applications in Ebstein anomaly or other malformations involved atrioventricular valves.
