To clarify the occurrence and distribution of broad bean wilt virus 2(BBWV2) on Rehmannia glutinosa, this study collected 87 R. glutinosa samples with typical symptoms of viral disease such as chlorosis and crumple from Wenxian county and Wuzhi county in Jiaozuo city, Henan province and Qiaocheng district in Bozhou city, Anhui province. The BBWV2 CP target band was amplified from 37 R. glutinosa samples by RT-PCR technology. The total detection rate reached 42.5%, among which 43.0% was detected in samples from Henan province. The detection rate in samples from Anhui province was 37.5%. 37 BBWV2 CP sequences were obtained by cloning and sequencing of BBWV2 positive samples(data has been submitted to GenBank, accession numbers: PP407959-PP407995), and the sequence analysis of these CP sequences with 91 other BBWV2 isolates in GenBank showed a high genetic diversity with a consistency rate of 70.8%-100%. Meanwhile, phylogenetic analysis showed that BBWV2 could be divided into three groups according to CP sequences, among which the BBWV2 in R. glutinosa isolates obtained in this study were all located in group 3. This study identified the differences in the occurrence, distribution, and genetic diversity of BBWV2 in R. glutinosa from Henan province and Anhui province and provided a theoretical basis for the prevention and control of BBWV2.

Objective:To detect the changes of left ventricular myocardial work parameters, and evaluate the left ventricular systolic function in patients with hyperglycemia during pregnancy by left ventricular pressure-strain loop (PSL).Methods:From June 2021 to March 2022, 97 pregnant women who were admitted to the Second Affiliated Hospital of Harbin Medical University and clinically diagnosed as gestational hyperglycemia were prospectively and randomly selected. According to the blood glucose level, the patients were divided into gestational dominant diabetes mellitus (ODM) group(39 cases) and gestational diabetes mellitus (GDM) group(58 cases). Meanwhile, another 62 healthy pregnant women were selected as control group. The basic clinical data of the pregnant women were collected, and the conventional two-dimensional parameters of the heart were collected. The global longitudinal strain (GLS) was analyzed by two-dimensional speckle tracking technique. Then the cuff blood pressure was used as the left ventricular pressure to construct a non-invasive left ventricular pressure-strain loop. The global myocardial work index (GWI), global constructive work (GCW), global wasted work (GWW) and global work efficiency (GWE) of each group were calculated and compared. The correlation between myocardial performance parameters and GLS, glycated hemoglobin(HbA 1c) were analyzed, and the independent factors affecting left ventricular systolic function were obtained by Logistic regression analysis. Twenty cases were randomly selected from the study subjects, and the intraclass correlation coefficients(ICC) of within the observers and between observers were calculated for repeatability test. Results:①Conventional ultrasound parameters: There were no significant differences among the three groups (all P>0.05). ②GLS and left ventricular myocardial performance parameters: GWI, GWE, GCW and GLS in GDM and ODM groups were significantly lower than those in control group (all P<0.001), GWW was significantly higher than control group ( P<0.001); GWI, GWE, GCW and GLS in ODM group were lower than those in GDM group (all P<0.001), while GWW was higher than control group ( P<0.001). ③GWE, GWI and GCW were negatively correlated with GLS ( r=-0.525, -0.408, -0.435; all P<0.05), GWW was positively correlated with GLS ( r=0.348, P<0.05). GWE, GWI and GCW were negatively correlated with HbA 1c ( r=-0.325, -0.262, -0.250; all P<0.05), while GWW was positively correlated with HbA 1c ( r=0.175, P<0.05). ④GWE, 1 h oral glucose tolerance test and HbA 1c were the influencing factors of left ventricular systolic function in patients with hyperglycemia during pregnancy. ⑤The predictive values of GWI, GWE, GCW, GWW and GLS for cardiac function in patients with gestational hyperglycemia were high, and the predictive value of GWE was the highest (AUC: 0.87, the best truncation value: 94.5%, specificity: 0.76, sensitivity: 0.82) and better than GLS. ⑥The repeatability of myocardial work parameters was better in both groups. Conclusions:Myocardial work parameters obtained by PSL are early and sensitive parameters for evaluating left ventricular systolic function impairment in patients with hyperglycemia during pregnancy which can provide reliable and objective quantitative indicators for early clinical intervention and improvement of prognosis.

Objective: To evaluate the efficacy and safety of Nocardia rubra cell wall skeleton (Nr-CWS) in the treatment of persistent cervical high-risk human papillomavirus (HR-HPV) infection. Methods: A randomized, double blind, multi-center trial was conducted. A total of 688 patients with clinically and pathologically confirmed HR-HPV infection of the cervix diagnosed in 13 hispital nationwide were recruited and divided into: (1) patients with simple HR-HPV infection lasting for 12 months or more; (2) patients with cervical intraepithelial neoplasia (CIN) Ⅰ and HR-HPV infection lasting for 12 months or more; (3) patients with the same HR-HPV subtype with no CINⅡ and more lesions after treatment with CINⅡ or CIN Ⅲ (CINⅡ/CIN Ⅲ). All participants were randomly divided into the test group and the control group at a ratio of 2∶1. The test group was locally treated with Nr-CWS freeze-dried powder and the control group was treated with freeze-dried powder without Nr-CWS. The efficacy and negative conversion rate of various subtypes of HR-HPV were evaluated at 1, 4, 8, and 12 months after treatment. The safety indicators of initial diagnosis and treatment were observed. Results: (1) This study included 555 patients with HR-HPV infection in the cervix (included 368 in the test group and 187 in the control group), with an age of (44.1±10.0) years. The baseline characteristics of the two groups of subjects, including age, proportion of Han people, weight, composition of HR-HPV subtypes, and proportion of each subgroup, were compared with no statistically significant differences (all P>0.05). (2) After 12 months of treatment, the effective rates of the test group and the control group were 91.0% (335/368) and 44.9% (84/187), respectively. The difference between the two groups was statistically significant (χ²=142.520, P<0.001). After 12 months of treatment, the negative conversion rates of HPV 16, 18, 52, and 58 infection in the test group were 79.2% (84/106), 73.3% (22/30), 83.1% (54/65), and 77.4% (48/62), respectively. The control group were 21.6% (11/51), 1/9, 35.1% (13/37), and 20.0% (8/40), respectively. The differences between the two groups were statistically significant (all P<0.001). (3) There were no statistically significant differences in vital signs (body weight, body temperature, respiration, pulse rate, systolic blood pressure, diastolic blood pressure, etc.) and laboratory routine indicators (blood cell analysis, urine routine examination) between the test group and the control group before treatment and at 1, 4, 8, and 12 months after treatment (all P>0.05); there was no statistically significant difference in the incidence of adverse reactions related to the investigational drug between the two groups of subjects [8.7% (32/368) vs 8.0% (15/187), respectively; χ²=0.073, P=0.787]. Conclusion: External use of Nr-CWS has good efficacy and safety in the treatment of high-risk HPV persistent infection in the cervix.

Objective To investigate the effects of microRNA( miR)-29a-3p on the proliferation and invasion of gastric cancer cells and analyze its related molecular mechanism. Methods The expression level of miR-29a-3p in gastric cancer cells was detected, and the role of miR-29a-3p in the proliferation, migration, and invasion of gastric cancer cells was evaluated. Western blotting and luciferase analysis showed that miR-29a-3p was directly bound to Serpinhl 3 ' -untranslated region(3' UTR). In addition, the effects of the miR-29a-3p/Serpinhl axis on the proliferation, migration, and invasion of gastric cancer cells were detected by MTT assay, colony formation assay, and Transwell assay in vitro. Results After transfection, the expression of miR-29a-3p in the miR-29a-3p mimic group was significantly higher than that in the miR-29a-3p negative control and blank group. After transfection, the proliferation of BGC823 cells decreased significantly. Luciferase analysis showed that miR-29a-3p inhibited the expression of Serpinhl by targeting the 3 ' UTR of Serpinhl. In addition, overexpression of miR-29a-3p significantly inhibited the proliferation, invasion, and migration of gastric cancer cells by targeting Serpinhl. Conclusion MiR-29a-3p can target Serpinhl and regulate the proliferation and invasion of gastric cancer cells.

Objective To study the effect of velvet antler polypeptides (VAP) on antioxidant in Alzheimer' s disease model mice. Methods Eight months old male amyloid precursor protein (APP)/presenilin-l (PS1) double transgenic mice were selected as Alzheimer' s disease (AD) model and divided into the model group and the VAP intervention group, 12 in each group. Besides, normal mice of the same brood (with no transgene) were recruited as a control group (n= 12).After 6 months of intragastric administration, behavior, morphology and oxidative stress related indicators were detected.SH-SY5 cells were used to establish AD model of damaged by Ap2535. The expression levels of APP and p-secreatase-l(BACE1) protein in mouse hippocampus were detected by Western blotting. VAP intervention group SH-SY5Y cells was cultured with VAP (500 g/L) and amyloid P(Ap) 2535(25 ixmol/L) for 24 hours. Control group cells were normally cultured by DMEM medium. Cell apoptosis, membrane potential, reactive oxygen species (ROS) levels and oxidative stress related indexes were detected. Results In animal models, compared with the model group, the escape latency of mice in the VAP intervention group was shortened (P<0. 05). The neuronal cells in the CA1 region of the hippocampus of the model group were reduced and arranged disorderly. The arrangement of the VAP intervention group was relatively regular, and the morphology was significantly improved. Compared with the model group, senile plaques were decreased in the VAP intervention group. Compared with the model group, the malondialdehyde (MDA) content ol the VAP intervention group increased, and the superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) content increased, the difference was statistically significant. Compared with the control group, the APP and BACE1 content in the model group increased. Compared with the model group, the contents of APP and BACE1 in the VAP intervention group decreased, and the difference was statistically significant (P<0. 05). In the cell model, the apoptosis rates of the VAP intervention group decreased. Compared with the model group, the mitochondrial membrane potential of the VAP intervention group increased, the content ol ROS decreased, the content of MDA decreased, and the content of SOD and GSH-Px increased. The difference were statistically significant (P<0. 05). Conclusion VAP has a protective effect on oxidative stress damage caused by Alzheimer' s disease model animals and cells, which may be achieved by reducing ROS production and increasing the activity of antioxidant enzymes to reduce Ap deposition.

After treatment, the water maze experiment was detected and recorded the escape latency and the number of crossing platforms of the mice; the ultrastructures of the synapse were observed by transmission electron microscopy; the expression of Rhs homolog gene family member A(RhoA) and Rho associated coiled-coil forming protein kinase II(ROCKII) in the hippocampal CAI area were observed by immunofluorescence. The expression levels of RhoA and ROCKII protein in the hippocampus were detected by Western blotting. The contents of hippocampus amyloid (3-protein(A(3),

Objective:To further understand the current status of diagnosis and treatment of endometriosis in China, the implementation of guideline in different levels of hospitals, and the need for continuing education in endometriosis among primary doctors.Methods:The survey was conducted in the form of convenience sampling questionnaire among the Wechat public platform. The doctors were free to participate in the investigation without any reward. All questions answered were assessed as valid questionnaire. The datas were collected on the questionnaire network platform and analyzed by SPSS 19.0.Results:Totally 1 494 valid questionnaires were collected in this survey. 60.17% (899/1 494) of them were from tertiary hospital, and 32.60% (487/1 494) were from grade two hospital. Only the hospitals where 9.97% (149/1 494) participants based opened the specialist clinic for endometriosis. 70.35% (1 051/1 494) of participants said they had read the second edition of guideline for the diagnosis and treatment of endometriosis which published in 2015. The American Society for Reproductive Medicine (ASRM) staging system was adopted in the clinical practices of only 25.03% (374/1 494) participants. And 18.74% (280/1 494) participants used the endometriosis fertility index (EFI) scoring during the laparoscopic surgery for endometriosis with infertility. 45.18% (675/1 494) of participants said they had not attended any academic conference on endometriosis in the past six months. 64.46% (963/1 494) of the participants believed their diagnosis and treatment in practice should be improved and standardized. 87.15% (1 302/1 494) of the participants expressed the hope that more conferences or workshops on endometriosis would be held.Conclusions:At presents, the diagnosis and treatment of endometriosis in China has been greatly improved, but the implementation of guidelines and the new concept is still a long-term job. The specialist clinic are held only in a few hospitals. It’s the expectation and voice of primary doctors to the association to organize the more academic congresses on endometriosis.

Objective:To evaluate the prognosis and related risk factors in patients who underwent surgical resection for pancreatic cancer with portal vein invasion.Methods:The clinical data of 66 patients with pancreatic cancer with portal vein invasion who underwent pancreatic combined with vascular resection and reconstruction at the Department of Hepatobiliary Surgery, Beijing Chaoyang Hospital Affiliated to Capital Medical University between January 2011 and December 2018 were retrospectively studied. There were 30 males and 36 females. Their age ranged from 35 years to 81 years, with a mean of 61.5 years. Post-operative survival outcomes were evaluated on follow-up, and the related risk factors for prognosis were analyzed. Kaplan-Meier method was used to construct survival curves, and the survival rates were compared by the log-rank test. Multivariate Cox regression was used to analyze prognostic factors.Results:All 66 patients successfully underwent the operations. There was no perioperative death. The postoperative complication rate was 28.8% (19/66). Sixty-five patients were followed up (follow-up rate 98.5%, 65/66). The overall 1-, 2- and 3-year survival rates were 53.3%, 30.4%, 23.4%, respectively, with a median survival of 13 months. Multivariate analysis showed that preoperative CA19-9 >400 U/ml ( RR=1.871, 95% CI: 1.123-3.117) and depth of venous invasion ( RR=1.713, 95% CI: 1.072-2.736) were independent risk factors of prognosis. The higher the preoperative CA19-9, and the deeper the venous invasion, the worse was the prognosis. Conclusion:Long-term prognosis of pancreatic carcinoma patients with portal vein invasion was poor. Preoperative CA19-9 >400 U/ml and depth of vascular invasion were the main risk factors of prognosis for patients with pancreatic carcinoma and portal vein invasion after surgical resection.
