Levels of lipids, lipoproteins and apolipoproteins in 59 patients with cerebral infarction were compared before and after therapy. Evening—Primrose—oil group (EPOG 32cases) was treated with EPO and routine drugs (low molecular dextran, piracetam, vitamine E), the routine—drug group (RDG 27cases) was treated only with above- mentioned routine drugs. After treating for one month the lab data demonstrated that the(HDL—c, HDL2—c and apo A—I levels in EPOG were significantly higher than)before treating (P0.05). All parameters above- mentioned in RDG had no significant change after treating.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease. The prevalence of NAFLD is increasing year by year in the world, which seriously threaten the public health. The pathogenesis of NAFLD is complex, and there is no specific treatment for NAFLD. Natural-derived compounds have the characteristics of multi-target and multi-mechanism, which can improve the curative effect and reduce the toxic and side effects by regulating multiple factors of the disease. They are ideal drugs for treating complex diseases and have unique advantages in improving NAFLD. However, low intestinal absorption, poor bioavailability, and single medicine efficiency limit the utilization of many compounds, and further drug development and clinical application are challenging. This paper reviews the research progress of natural-derived compounds in the prevention and treatment of NAFLD in recent years, analyzes the existing problems, and discusses the improvement strategies, so as to provide reference for related research.

Survivin-D53A (SVV-D53A) is a dominant-negative mutant survivin, which represents a potential promising target for cancer gene therapy. The present study was designed to determine whether SVV-D53A plasmid encapsuled by DOTAP: Chol liposome would have the anti-tumor activity against SPC-A1 lung adenocarcinoma, and to detect the possible mechanisms. In our experiment, SPC-A1 cells were transfected in vitro with SVV-D53A plasmid and examined for protein expression by Western blot, then flow cytometric analysis was used to detect apoptosis. SPC-A1 lung adenocarcinoma xenografts were established in vivo in the nude mice, which received the i. v. administrations of SVV-D53A plasmid/liposome complexes. After mice were sacrificed, the paraffin-embedded tumor tissue sections were used for proliferating cell nuclear antigen (PCNA) expression and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Compared with the control group, the mice treated with SVV-D53A plasmid had an obviously reduced tumor volume, with high level of apoptosis and decreased cell proliferation in tumor tissue. The research results proved that the administration of SVV-D53A plasmid resulted in significant inhibition of SPC-A1 cells both in vitro and in vivo. The functional mechanism is that the anti-tumor response causes and induces tumor cell apoptosis.

[Objective] To construct a database for the genetic polymorphism of 18 STR loci (D8S1179, D21S11, D7S820, CSFIPO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, VWA, TPOX, D18S51, D5S818, FGA, PentaE, PentaD, SE33) in Hart population from Zhejiang province. To investigate the application of 18 STR loci in the field of paternity testing and prenatal diagnosis. [Methods] Fluorescent dye labeling multiplex STR-PCR, capillary electrophoresis and DNA sequencer GeneScan were adopted in genotyping 598 unrelated samples collected from Han population in Zhejiang province. 18-STR database was established and analyzed. Population comparison was conducted between Han population in Zhejiang province and 8 other population. 15-STR and 18-STR identification system were compared in 497 paternity testing cases. [Results] We observed the distribution of 18 STR loci in Han population meet Hardy-Weinberge equilibrium and was different from other 8 population (X~2 test, P>0.05). Statistical results showed that the heterozygosis (He) ranged from 0.630 to 0.942. The combined power of discrimination was>0.9999999999. Compared with 15-STR identification system, higher paternity index scores and higher exclusion rate were obtained with 18-STR identification system in dual-case paternity test and mutation identification. One trisomy 21 fetus was found in a prenatal paternity test case which had two characteristic genotypes in 2 STR loci of D21S11 and Penta D. [Conclusions] The 18 loci were relatively highly genetic polymorphic in Zhejiang Han population and could be used for paternity testing. Some STR loci could be used in prenatal diagnosis for aneuploidy.

The ralationship between traditional Chinese medicine (TCM) and intestinal microecology is increasingly being given more and more attention. Combined with the devolopment of intestinal microecology disciplines, effects of TCM on regulation of intestinal microecology have been gradually explained. Both clinical studies and animal experiments have confirmed that TCM can maintain the balance of intestinal microecology and regulate the intestinal flora. The author arrangemented the documents related to Chinese herbal compound adjusting intestinal flora in the recent ten years, summarized that the Chinese herbal compound which can strength spleen and replenish Qi, relax bowels and regulate Qi, dissipate dampness and check diarrhea, clear away heat and toxic materials, promote digestion and relieve stasis had certain regulation effects on intestinal microecology, providing basis for revealing the TCM essence of intestinal microecology.

Objective: To explore the association of hypertriglyceridemic waist phenotype ( HTGW ) with impaired fasting glucose ( IFG ) and diabetes, so as to provide reference for the early prevention and control of diabetes. Methods: The survey was conducted among 35 to 75-year-old residents in 8 project sites in Jiangsu Province from 2015 to 2019. The information about demography and lifestyle was collected by the general information questionnaire and the primary screening questionnaire from the National Center for Cardiovascular Diseases; waist circumference, height, weight, triglyceride, high-density lipoprotein cholesterol, total cholesterol and fasting plasma glucose were measured. The multinomial logistic regression model was employed to analyze the association of HTGW with IFG and diabetes. Results: A total of 118 383 subjects were included, among whom 21 851 cases of HTGW, 27 245 cases of IFG and 22 899 cases of diabetes were identified, with the prevalence of 18.46%, 23.01% and 19.34%. The multinomial logistic regression analysis showed HTGW was statistically associated with IFG ( OR=1.414, 95%CI: 1.343-1.489 ) and diabetes ( OR=2.216, 95%CI: 2.098-2.341 ). Conclusion HTGW is associated with IFG and diabetes, which make it possible to be an indicator for screening and assessment of glucose abnormality in middle-aged and elderly population.

OBJECTIVETo observe the effect of nourishing Yin, strengthening Qi and activating blood decoction on Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression.

METHODThirty-two NOD mice were randomly divided into the model group, the traditional Chinese medicine group (TCM group, orally given 0.4 mL nourishing Yin, strengthening Qi and activating blood decoction as per 100 g x kg(-1) everyday), the hydroxychloroquine group (given 0.4 mL hydroxychloroquine as per 60 mg x kg(-1) everyday), the traditional Chinese medicine and western medicine group (TCM WM group, given nourishing Yin, Strengthening Qi and activating blood decoction 50 g x kg(-1) and hydroxychloroquine 60 mg x kg(-1), 0.4 mL everyday), with eight mice in each group. Eight Balb/C mice were selected as the normal control group (normal group). All of mice were killed after eight weeks, and their submaxillary glands were dissected. The expression levels of Fas/FasL were examined by immunohistochemical method, and the FasL mRNA was detected by RT-PCR.

RESULTThe expression levels of Fas/FasL in salivary glands of the model group were higher than that of other groups (P < 0.05). The expression level of FasL of the normal group was much lower than that in the hydroxychloroquine group (P < 0.05). The relative expression level of Fas mRNA in salivary glands of the model group was higher than that in other groups, but the control group was notably lower than other groups (P < 0.05). The expression level of FasL mRNA in salivary glands of the model group was higher than that in TCM and TCM WM groups (P < 0.05). But the expression level in TCM WM group was notably lower than the hydroxychloroquine group (P < 0.05).

CONCLUSIONThe nourishing Yin, strengthening Qi and activating blood decoction could down-regulate the expression level of Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression, and had a better efficacy after being combined with hydroxychloroquine. The nourishing Yin, strengthening Qi and activating blood decoction might treat the Sjogren's Syndrome by reducing apoptosis which is regulated by Fas/FasL

Objective To investigate the effects of B.adolescentis and L.acidophilus in treatment of dextran sulphate sodium (DSS)-induced ulcerative colitis(UC) in mice and their potential mechanisms. Methods Seventy-five BABL/C mice were randomly divided into control,saline (NS),B.adolescentis BF0624 treatment (B),L.acidophilus LT0637 treatment (L) and salicylazosulpha-pyridine treatment (S) groups.Except control group,the other four groups were received DSS to induce ulcerative colitis. The weight-loss,fecal trait and bleeding were recorded every day.Colonic length and histological scores were evaluated on day 3,5 and 7.The gene and protein expression of hot shock protein (HSP)70, glucocorticoid receptor (GR),interleukin (IL)-10 and tumor necrosis factor (TNF)-α were detected by Western blot and reverse polymerase chain reaction (RT-PCR) respectively.Results B.adolescentis BF0624 and L.acidophilus LT0637 could relieve the inflammatory reaction of the experimental UC.The DAI scores were 1.84±0.4 in L group on day 3,which was lower than that in NS group (2.8±1.0).The DAI scores in all treatment groups were decreased on day 5.Compared with NS group[(8.1±0.6)cm ], the colon length on day 8 were (9.0±0.6)cm in B group,(9.35±0.6)era in L group and (8.8±1.1)cm in S group (P＜0.05).The colonic mucosa was improved pathohistologically in L group (6.0±1.0) on day 8.The expression of HSP70 and IL-10 in B and L groups were up-regulated and the expression of TNF-α was down-regulated.Conclusions Both B.adolescentis BF0624 and L.acidophilus LT0637 were effective in treatment of acute ulcerative colitis.The potential mechanism of two probiotics may be related with up-regulation of HSPT0 and IL-10 expressions and down-regulation of TNF-α expression.

Objective To investigate the radiosensitization effects of the combination treatment of clioquinol (CQ) and zinc on human cervical cell line HeLa in vitro.Methods Cells were divided into the 4 groups:controls,drug,radiation,and combined drug and radiation group.Cytotoxic effect of CQ and zinc on cell viability was determined by CCK-8 assay.Radiosensitization effect of CQ and zinc on HeLa cells was detected by colongenic assay,and the single-hit multi-target model was used to stimulate the doseresponse curve of survival and to calculate radiosensitization parameters.The cell cycle and apoptosis of HeLa cells were analyzed with flow cytometry.Luciferase reporter assay was used to study NF-κB activity of HeLa cells.Results The combination of CQ and zinc inhibited cell growth in a dose-dependent manner (F =188.00,P ＜ 0.01).The mean lethal dose was 3.16 and 2.04 Gy for radiation group and combined drug and radiation group,respectively,and hence the SER was 1.55.Compared with the radiation group,the ratio of G2-phase cells in the combined drug and radiation group decreased(t =10.39,P ＜ 0.05),the apoptosis rate increased at 24 h post-irradiation (t =5.64,P ＜ 0.01),and the NF-κB activity decreased (t =21.42,P ＜ 0.05).Compared to the control group,the NF-κB activity increased in the radiation group(t=6.23,P＜0.05),but decreased in the drug group(t =12.48,P＜0.05).Conclusions The combination of CQ and zinc could increase the radiosensitivity of HeLa cells by decreasing the ratio of G2-phase cells,increasing apoptosis and the inhibiting of NF-κB activity.

Objective To evaluate the changes of left ventricular (LV) bulk rotation and untwisting in transplanted hearts using 2-dimensional speckle tracking imaging(STI).Methods Basal and apical LV short-axis images were acquired in 15 heart transplant recipients 3 months post surgery(HT group) and 56 healthy control subjects.Basal and apical rotation versus time profiles were drawn using 2-dimensional STI software.Appropriate values were chosen from the dataset obtained and compared between two groups.Results ①Compared with the control group,the heart rate,anterior-posterior diameter of left atrium,enddiastolic interventricular septum thickness,left ventricular posterior wall thickness,isovolumic relaxation time and E/e ratio were significantly increased,e and a values were decreased significantly in HT group (P ＜ 0.05).② No significant difference was noticed in the peak degrees of LV bulk rotation,the degrees of LV bulk rotation at the time of aortic valve closure and mitral valve opening (P =0.700,0.984,0.495,respectively) between 2 groups.In both groups,systolic rotation reached its maximum at end-systole [(96.1 ± 8.4) ％ in HT group vs (100.5 ± 6.3) ％ in control group,P =0.065].③Significant decreases in untwisting rate and trend untwisting variables were observed in the HT group(P ＜0.001).Conclusions 3 months after transplanted,left ventricular bulk rotation of cardiac allografts remained normal,and significant decreases in both untwisting rate and trend untwisting variables showed that the diastolic function of cardiac allografts was impaired.
