Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Lycophytes and seed plants constitute the typical vascular plants. Lycophytes have been thought to have no paleo-polyploidization although the event is known to be critical for the fast expansion of seed plants. Here, genomic analyses including the homologous gene dot plot analysis detected multiple paleo-polyploidization events, with one occurring approximately 13-15 million years ago (MYA) and another about 125-142 MYA, during the evolution of the genome of Selaginella moellendorffii, a model lycophyte. In addition, comparative analysis of reconstructed ancestral genomes of lycophytes and angiosperms suggested that lycophytes were affected by more paleo-polyploidization events than seed plants. Results from the present genomic analyses indicate that paleo-polyploidization has contributed to the successful establishment of both lineages-lycophytes and seed plants-of vascular plants.

Objective To investigate the value of serum high sensitive C reactive protein(hs-CRP) in the risk stratification and prognosis evaluation in the patients with coronary heart disease and PCI operation.Methods One hundred and sixty-three cases of coronary heart disease and undergoing PCI in this hospital from March 2013 to September 2015 were selected and performed the coronary angiography examination before operation.Then the patients were divided into 3 groups according to the hs-CRP level.The Gensini score was used to judge the blood vessel stenosis degree.The patients were followed up within six months after surgery.The major cardiovascular events were recorded and the relationship between the hs-CRP level with the number of diseased vessels,Gensini score,MACE and other coronary heart disease risk factors was analyzed.Results Hypertension and hs-CRP level had statistically significant difference among 3 groups(P＜0.05);preoperative hs-CRP level showed positive correlation with hs-cTnT level (r =0.44,P＜ 0.001),while the hs-CRP was negatively correlated with the HDL-C level (r =-0.18,P =0.003);with the Gemini score elevation,the hs-CRP level was similarly elevated,the hs-CRP levels in the patients with severe,moderate and mild vascular stenosis evaluated by Gensini's score were(17.11±9.58),(10.02±3.59),(4.11±1.62)mg/L respectively,the difference among them had statistical significance(F=37.21,P＜0.05).Within postoperative six months,the MACE occurrence rates in 3 groups were 32.1％,52.9 ％ and 59.2 ％ respectively,the differences among the three groups were statistically significant(x2 =13.523,P =0.001),and the target lesion blood supply reconstruction rate had statistically significant difference(x2 =7.522,P =0.022).The hsCRP level was an independent risk factor of MACE occurrence(OR =2.06,95 ％ CI:1.31-3.42,P=0.005).Conclusion Serum hs-CRP is an independent risk factor for cardiovascular events occurrence after PCI surgery in the patients with coronary heart disease.

The dual luciferase reporter gene system provides sensitive readout, while it relies on a constitutively-expressed control gene for readout normalization. However, most standard control reporter genes are not constitutively expressed under all conditions. Here, we report an effective method to construct a control reporter plasmid for the dual luciferase reporter gene system that would be suitable for hormone research in silkworm cell lines. First, we modified BmVgP78M, a stably-expressed constitutive promoter in silkworm cells by mutating its hormone-related element. Then, we constructed the pRL-VgP78M control reporter plasmid by replacing the SV40 promoter and chimeric intron sequences in pRL-SV40 with the BmVgP78M sequence. Finally, we confirmed that the pRL-VgP78M control reporter plasmid could be stably expressed in silkworm cell lines via cell transfection experiments, and it was unresponsive to the induction of ecdysone, juvenile hormone, or their transcription factors. We thus obtained a control reporter plasmid pRL-VgP78M that could be expressed stably and moderately in silkworm cells. It can be readily used as the control reporter plasmid of the dual luciferase reporter gene system for hormone research in silkworm cell lines. It will also provide a reference for construction of control reporter plasmids of dual luciferase reporter gene systems that are adaptable to cell lines isolated from other species.

Objective To observe the effects of herb-partition moxibustion at navel on the expressions of Bcl-2 and Bax in rats with premature ovarian failure (POF); To explore its mechanism underlying improvement of POF. Methods POF model was established by intraperitoneal injection of cyclophosphamide. Forty-eight Female Wistar rats were randomly divided into normal group, model group, moxibustion group and Western medicine group, with 12 rats in each group. Rats of moxibustion group were treated with herb-partition moxibustion at navel (Shenque, CV8), 30 min/d, once every other day; rats of Western medicine group were given intragastric dose of estradiol valerate, once a day, for 14 d. The protein and mRNA expressions of Bax and Bcl-2 in ovarian granulosa cells were detected by immunohistochemal method, Western blot and qRT-PCR, respectively.Results The weights of ovaries in the model group rats were significantly lower than those in the normal group (P<0.05). The expressions of Bcl-2 and Bax protein in ovarian tissue of each group were mainly expressed brown coloration and in the cytoplasm of cells. The range of Bax protein in granulosa cells of moxibustion group and Western medicine group was significantly less than that in model group. The range of Bcl-2 in moxibustion group and Western medicine group was significantly larger than that in model group. Compared with the normal group, the expressions of Bcl-2 protein and mRNA in the model group rats significantly decreased (P<0.05,P<0.01), and the expression of Bax protein and mRNA significantly increased (P<0.05,P<0.01). The expression level of Bcl-2 protein and mRNA was significantly higher in the moxibustion group and in the western medicine group than that in the model group (P<0.05,P<0.01). The expression level of Bax protein and mRNA in the moxibustion group was significantly lower than that in the model group (P<0.05,P<0.01). ConclusionThe herb-partition moxibustion at navel can improve the function of ovaries by up regulating the expression of Bcl-2 and down regulating the expression of Bax in POF rats model.

Objective To investigate the risky sexual behaviors,associated factors and characteristics of sexual network among clients receiving methadone maintenance treatment (MMT) at the clinics in Taizhou prefecture of Zhejiang province.Methods A cross-sectional survey was conducted.Data was collected through questionnaire and from the national unified MMT system.Urine was collected to test heroin,methamphetamine,3,4-methylenedioxymethamphetamine (MDMA) and ketamine.Blood was collected to test infections on HIV,hepatitis C vims(HCV) and syphilis.Results Totally,362 clients were recruited.Most of the clients were male (88.7％),31--40 year-olds (54.5％),married (61.6％) and having received junior high school education (56.6％).85.1％ of them received urine test with 82(26.6％) positive for heroin,21 (6.8％) positive for methamphetamine,19 (6.2％) positive for MDMA and none for ketamine.77.1％ of them received blood test,and prevalence rates for HIV,HCV and syphilis were 1.1％,36.7％ and 3.6％.19.5％ of the clients who had sex in the past 6 months.Factors as having multiple sexual partners and positive for club drugs were under higher risk.Sexual networking seemed to be loose,linear and acyclic among this population but overlapping with the drug-using network.Conclusion Effective and targeted interventions should be taken among the MMT clients since continuing drug use and HIV/STD related sexual behavior were found common in them,suggesting there was a risk of HIV/STD transmission in this ppulation.

Objective:This study aimed to detect the expression of annexin A1 in human non-small cell lung cancer (NSCLC) and to explore its clinical significance. Methods:We detected the expression levels of annexin A1 in NSCLC and the same patient's dis-tal cancerous tissue (from the edge of the tumor >5 cm) by real-time fluorescence quantitative polymerase chain reaction (real-time PCR), Western blot, and immunohistochemical methods, and then analyzed their correlation with clinical pathological parameters. Re-sults: Real-time PCR showed that the expression of annexin A1 mRNA in NSCLC was higher than that of distal cancerous tissue (0.574±1.403 vs. 0.240±0.893, t=2.060, P=0.045). Moreover, the expression of annexin A1 in NSCLC was associated with the degree of differentiation, lymph node metastasis, and TNM staging (P<0.05), but independent of gender, age, smoking history, tumor size, and histological type (P>0.05). Western blot and immunohistochemistry revealed that the expression of annexin A1 protein in NSCLC was higher than that of distal cancerous tissue. Conclusion:Annexin A1 is highly expressed in the cancer tissues of patients with NSCLC, which may be correlated with the occurrence and development of tumor and its invasion and metastasis.
