Aim To compare the inhibition of lipid peroxidation of ethyl acetate extract( EAE) and n-buta-nol( BE) extract from Coreopsis tinctoria Nutt. in vitro. To investigate the parameters such as body weight, bio-chemical indexes in plasma, and viscera indexes on type 2 diabetes mice by intraperitoneal injection of streptozotocin ( STZ ) . Methods The extracts were prepared by response surface methodology. The ex-tracts were suspended in distilled water and defatted with petroleum ether. The aqueous layer was succes-sively extracted with ethyl acetate and n-butanol. The inhibition of lipid peroxidation activity was determined by thiobarbituric acid method. The effects of extract BE on diabetic mice were observed at the dosage of 0. 2,0. 4,0. 8 g·kg-1 ( ig) for 4 weeks. The parame-ters were observed such as weight of body changes, or-gan coefficients of liver, pancreas and kidney, bio-chemical indexes in plasma and viscera pathological sections. Results In the linoleic acid reaction system, the SC50 value of the EAE and BE was ( 443. 96 ± 11. 24) mg·L-1, (840. 29 ± 16. 38) mg·L-1, re-spectively, and that in rat liver homogenate was (23. 59 ± 3. 67 ) mg · L-1 , ( 60. 37 ± 4. 27 ) mg · L-1 , respectively. Compared with diabetic model group, BE could significantly improve the trend of weight loss, and increase viscera indexes. The patho-logical sections showed that BE had the recovery and improvement effects on the damage of liver, pancreas and kidney. Conclusions The extracts of C. tinctoria have a certain anti-lipid peroxidation activity in vitro. And BE has a certain capacity to improve and repair damaged organs for DM mice.

Objective To explore the normal values for two-dimension solid state high resolution anorectal manometry (HRAM) in healthy adult volunteers.Methods The healthy adult volunteers were recruited by advertisement and underwent solid state HRAM in the left lateral position.Anorectal pressures and rectal sensation were recorded and analyzed.Results (1) A total of 126 Chinese healthy adult volunteers (male:50 cases (39.7％);age:(37.5 ± 14.2) years old) were recruited in this study.(2)Mean anal resting pressure (MERP) was (71.8 ± 17.3) mmHg (1 mmHg =0.133 kPa).Maximum anal resting pressure (MARP) was (79.3 ± 17.8) mmHg,Maximum anal squeeze pressure (MSP) was (178.7 ± 52.8) mmHg.Anal high pressure zone (HPZ) length was (3.4 ± 0.6) cm.During simulated evacuation,residual anal pressure (RAP) was (63.8 ±20.5) mmHg,and anal relaxation rate (ARR) was (37.0 ± 11.5) ％.Rectal threshold volume for first sensation (FST),desire to defecate (DDT),urgency to defecate (UDT) and maximum discomfort (MDT) was (47.4 ±10.0) ml,(84.5 ±18.2) ml,(125.8 ± 28.5) ml,and (175.5 ±36.1) ml,respectively.(3) Compared with female subjects,male subjects had higher MSP [(211.0 ± 50.7) mmHg vs (157.5 ± 42.5) mmHg],RAP [(71.6 ± 18.1) mmHg vs (58.8 ± 20.5) mmHg]and rectal MDT[(187.0 ±36.4) mmHg vs (168.0 ±34.1)mmHg],but lower ARR [(32.1 ±8.0)％ vs (40.2 ±12.3)％],all P＜0.01.(4) MERP,MARP,MSP and rectal MDT were higher in young group (≤ 40 years old),all P ＜ 0.05.Conclusions These observations provide normal values for two-dimension solid state HRAM,which have significant difference between genders and different age groups.

Objective:To investigate the effect of elevated low-density lipoprotein(LDL)cholesterol on the release of endothelial microvesicles into the circulatory system in elderly patients with obstructive sleep apnea(OSA).Methods:This was a case-control study.A total of 69 elderly inpatients aged ≥ 60 years were divided into the OSA group(n=48)and the normal control group(n=21)based on the apnea/hypopnea index(AHI). Sleep monitoring was carried out in the two groups, and venous blood samples were taken after the monitoring.Density gradient centrifugation was used to extract microparticles and flow cytometry was used to analyze patients' blood levels of endothelial microvesicles.Blood lipid levels of patients were measured by biochemical analysis methods.The correlation between LDL cholesterol levels and endothelial microvesicles in OSA patients was analyzed.Results:LDL cholesterol levels were higher in OSA patients than in normal controls(2.6±0.6 mmol/L vs.2.2±0.7 mmol/L, t=2.089, P=0.041). Endothelial microvesicle levels were elevated in OSA patients compared with the normal controls[(28.2±12.2)×10 -6events/L vs.(19.6±7.8)×10 -6 events/L, t=-3.164, P=0.003]. Endothelial microvesicle levels increased in OSA patients with elevated LDL cholesterol compared with OSA patients with normal LDL cholesterol[(39.3±12.6)×10 -6 events/L vs.(28.2±12.2)×10 -6 events/L, t=2.899, P=0.006]. There was a significant correlation between LDL cholesterol levels and endothelial microvesicle levels in OSA patients( r=0.497, P=0.032), while levels of HDL, total cholesterol, triglycerides, blood pressure and blood glucose had no significant correlation with endothelial microvesicle levels. Conclusions:The level of endothelial microvesicles released into the circulation is higher in elderly OSA patients than in normal elderly people, and the elevated concentration of LDL can further promote the release of endothelial microvesicles in OSA patients.

Objective To analyze the incidence and survival trend of malignant tumors in urban residents of Shenyang from 2011 to 2018. Methods The Shenyang tumor registration report system was used to collect the onset data and survival data of patients with malignant tumor from 2011 to 2018.The crude incidence, age-standardized rate, cumulative rate (0-74 years old), truncated rate (35-64 years old), survival rate, and incidence and survival rank were calculated.The observed survival rate was calculated by the life table method.The expected survival rate and relative survival rate were calculated by EdererⅡmethod.Using Joinpoint 3.5.3 software, the annual percentage change in incidence rate and survival rate (APC%) were calculated.SPSS23.0 software was used for the chi square tests of males and females. Results The crude incidence of malignant tumors in Shenyang, age-standardized incidence rates by Chinese standard population and world standard population were 364.70/10 million, 190.00/10 million and 185.63/10 million, respectively.The cumulative rate (0-74 years old) was 21.17%, and the truncated rate (35-64 years old) was 311.66/10 million in the years 2011-2018.The top five incidence rates of males are lung, colorectal, liver, stomach, and bladder cancer, whereas those of females were breast, lung, colorectal, uterine, and thyroid cancer.The incidence rate of malignant tumors increased in 8 years (P=0.00, P=0.67), and the incidence rate was higher in males than that in females (χ²=201.63, P < 0.05).The 5-year survival rate of malignant tumors was 40.49%, and the relative survival rate was 47.84% from 2011 to 2015.The five survival rates of males were in the order of thyroid, kidney, bladder, colon-rectum, and prostate cancer.The five survival rates of females were in the order of thyroid, breast, uterus, cervix, and colon-rectum cancer.The 5-year survival rate showed an upward trend (APC%=7.41, P=0.04).The survival rate of females was higher than that of males (χ²=187.62, P < 0.05). Conclusion The incidence rate and survival rate of malignant tumor in Shenyang urban residents increase yearly from 2011 to 2018.The incidence rate of males is higher than that of females, and the survival rate of males is lower than that of females.The incidence rate and survival rate of tumors differ much in sequence.

OBJECTIVE:To study induction effect of euphornin on the apoptosis of cervical cancer Hela cells and its mechanism. METHODS:The cervical cancer Hela cells were divided into blank control group,cisplatin group(positive control, 10 mg/L) and euphornin low-dose,medium-dose and high-dose groups (50,100,200 mg/L). They were treated with relevant medicine. The inhibitory effect of Hela cells proliferation was tested by MTT assay after 24,48,72 h of medicine treatment. The apoptotic rate of Hela cells was measured by flow cytometry after 48 h of medicine treatment. Morphology of nucleus was detected by Hoechst 33258 staining. The protein expression of Cyt-C,Bcl-2,Bax,Caspase-3,Caspase-8,Caspase-9 and Caspase-10 were detected by Western blot assay. RESULTS:Compared with blank control group,inhibitory rate of cell proliferation and cell apoptosis rate were increased significantly in cisplatin group and euphornin groups(P＜0.05 or P＜0.01),and obvious staining, deformation,shrinking,fragmentation or apoptotic bodies was found in nucleus. Compared with blank control group,the protein expression levels of Cyt-C,Caspase-8 and Caspase-9 in euphornin low-dose,medium-dose and high-dose groups were increased significantly,while the protein expression level of Bcl-2 and Bcl-2/Bax ratio were decreased significantly(P＜0.05 or P＜0.01);the protein expression levels of Bax,Caspase-3 and Caspase-10 in euphornin medium-dose and high-dose groups were increased significantly(P＜0.05 or P＜0.01). CONCLUSIONS:Euphornin can significantly inhibit the proliferation of Hela cell and promote cell apoptosis,the effect of which will be achieved by activating the Caspase-dependent mitochondrion apoptosis pathway.

Objective To evaluate the damage of the salivary gland in Sjogren's syndrome (SS)patients with normal Young's modulus value (YMV) using salivary gland dynamic imaging (SGDI).Methods A total of 78 parotid glands and submandibular glands of SS patients and 100 parotid glands and submandibular glands of healthy people were collected in this retrospective study.The difference of YMV between 2 groups was analyzed with two-sample t test;receiver operating characteristic (ROC) curves of YMV were drawn to calculate the area under carve (AUC) and cut-off values.SGDI was used to observe the uptake ratio of 15 min (UR15) value in the SS salivary glands with normal YMV.Results The YMV of left parotid/submandibular glands and right parotid/submandibular glands were not statistically different in both SS patients and healthy people (t values:from-1.192 to-0.404,all P＞0.05).The YMV of parotid/submandibular glands in SS patients was higher than that in healthy people:(15.39±8.08) vs (9.33±2.21) kPa,(14.35±5.33) vs (9.18±2.36) kPa (t values:7.169 and 8.662,both P＜0.05).ROC curves showed that the AUC of parotid glands and submandibular glands were 0.78 and 0.83.As the cut-off values of YMV were 10.85 kPa and 10.95 kPa,the sensitivity were 69.23％ (54/78) and 73.08％ (57/78),the specificity were 77.00％ (77/100) and 83.00％ (83/100),the positive predictive value were 70.13％ (54/77) and 77.03％ (57/74),the negative predictive value were 76.24％ (77/101) and 79.81％ (83/104),respectively.There was no statistically difference between YMV and UR15 for evaluating the SS parotid glands and submandibular glands (x2 values:0.963 and 0.896,both P＞0.05).The UR15 value of 78 SS parotid glands and submandibular glands were 1.42±0.97 and 1.19±0.83,respectively.About 58.33％ (14/24) parotid glands with normal YMV (＜10.85 kPa) and 76.19％ (16/21) submandibular glands with normal YMV (＜10.95 kPa)had reduced cellular uptake in SS patients.Conclusions Parotid glands and submandibular glands in SS patients are damaged,and the tissue hardness is increased.SGDI can discover the cellular damage in SS salivary glands with normal YMV.

Objective: This study aimed to analyze the association between the characteristics of egocentric network and HIV prevalence among men who have sex with men (MSM) through social network analysis. Methods: The study was conducted in Guangzhou city from November 2016 to June 2017 using convenient sampling method. Participants were recruited from 13 voluntary counseling and testing (VCT) locations. Data were collected by using nomination generation and nomination interpretation methods. Questionnaire includes two parts, the first part about the social tie, and the second one about social demography and behavioral characteristics of respondents and their nominees. The multivariate logistic regression was applied to quantify the association. Results: 8.67%(93/1 073) HIV antibody positive MSM had been detected in 1 073 respondents who nominated 4 301 partners in total. Compared to egocentric sexual network with a size of 1-2, the size of sexual network larger than 3 (OR=1.68, 95%CI: 1.07-2.65) were associated with HIV infection. Compared to egocentric risk sexual network with a size of 1-2, the size of risk sexual networks larger than 3 (OR=1.87, 95%CI: 1.06-3.31) were associated with HIV infection. There were no significant association between marital similarity of respondents and their nominees, the type of the relationship of sexual partners and HIV prevalence (P>0.05). Conclusion The composition of social network in MSM is related to their susceptibility of HIV infection. MSM population with a large sexual network is more susceptible to HIV infection.

Objective To investigate the clinical and prognostic significance of ABO promotor methylation level in adult patients with leukemia and myelodydysplastic syndrome(MDS). Methods ABO promoter methylation level of 182 malignant hematological disease patients and 68 normal controls were detected by bisulfite sequencing PCR. Then clinical features and outcome were compared between hypermethylation group and hypomethylation group. Results The median methylation rate of ABO promoter in newly diagnosed acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL) were 46.98％ and 11.01％ respectively, which were both higher than that in controls (2.30％, P<0.05). The methylation rates in remission AML and ALL were 1.58％and 2.30％respectively, which were comparable with that in normal group (P>0.05). As to relapse AML and ALL, methylation rates were 41.26％ and 17.50％respectively, also significantly higher than that in controls (P<0.05).In patients with chronic myeloid leukemia (CML) chronic phase, the median methylation rate was 1.00％, which was similar to normal group. But a CML patient who transformed to ALL hadextremely high methylation rate 92.56％. The median methylation rate in patients with MDS significantly elevated as 5.81％ compared with that in controls (P<0.05). The median overall survival (OS) of ALL and AML (non-M3) patients with hypermethylation were 12.5 months and 15.3 months, which were significantly shorter than those with hypomethylation (24.0 months and 20.0 months) (P<0.05). The median disease-free survival (DFS) of ALL and AML (non-M3) patients with hypermethylation were 9.9 months and 12.0 months, which were significantly shorter than those with hypomethylation (22.3 months and 18.5 months), (P<0.05). Multivariable analysis suggested that ABO promoter methylation level was an independent predictive factor of OS and DFS in ALL and AML (non-M3) patients. Conclusion ABO promoter hypermethylation is closely related to genesis, development and prognosis of leukemia and MDS. Hypermethylationis related to a clinical poor prognosis compare with hypomethylation.
