ObjectiveTo investigate the association of nonalcoholic fatty liver disease (NAFLD) with insulin resistance and dyslipidemia in patients with type 2 diabetes mellitus,and to analyze the risk factors.Methods A total of 200 patients with type 2 diabetes mellitus including 99 with NAFLD and 101 without NAFLD were recruited.Height,weight,waist circumference,hip circumference,liver enzymes,blood lipids,fasting and postprandial blood glucose,insulin,C-peptide,and HbA1C levels were detected.Body mass index ( BMI),waist-hip ratio( WHR),and improved insulin and C-peptide index(HOMA-C-peptide) were calculated and compared between two groups.ResultsCompared with non-NAFLD group,weight,BMI,waist circumference,hip circumference,alanine aminotransferase ( ALT),aspartate aminotransferase,triglyceride ( TG ),total cholesterol ( TC ),low density lipoprotein-cholesterol(LDL-C) were significantly higher in NAFLD group( all P＜0.01 ),while age,duration,and high density lipoprotein-cholesterol were lower( all P＜0.05 ).The incidence of combined hyperlipidemia,especially hypertriglyceridemia,was significantly higher in NAFLD group( P＜0.01 ).Fasting and postprandial 1 h blood glucose [ ( 2.07 ±0.36 vs 1.83 ±0.43 ) mmol/L,( 14.04 ± 3.96 vs 12.59 ± 3.90 ) mmol/L ],fasting and postprandial 1 h Cpeptide [ (2.79± 1.15 vs 2.08±1.29 ) ng/ml,( 1.33 ±0.45 vs 1.12±0.54) ng/ml ],HbA1C [ (2.09±0.33 vs 1.96±0.28) ％ ],and HOMA-C-peptide index were significantly increased in NAFLD group ( P ＜ 0.05 or P ＜ 0.01 ).Logistic analysis showed that TG,BMI,and ALT were the major risk factors of NAFLD in type 2 diabetes mellitus( P＜0.05 or P＜0.01 ).ConclusionTriglyceridemia,obesity,and raised ALT level were significantly associated with an increased risk of NAFLD in patients with type 2 diabetes mellitus.

To culture bone marrow mesenchymal stem cells (BMSCs) of rat in vitro and observe HSV-1 infection on BMSCs, BMSCs were separated from the bone marrow and identified by alizarin red staining and detection of ALP. The morphology of HSV-1 infected BMSCs and the CPE were observed. The total DNA was extracted from HSV-1 infected BMSCs and the desired specific gene fragment of 477bp of HSV-1 was amplified by PCR. Results showed that after BMSCs were induced by mineral-fluid for 14 days, the ALP level was increased and the nodule calcification was formed. The induced BMSCs were manifested to have the characteristics of osteoblasts. CPE couldn't be found in HSV-1 latently infected BMSCs but the 477bp gene fragment was still detectable. HSV-1 could establish latent infection in BMSCs after 7 passages. This study indicated that rat BMSCs could be induced to differentiate into osteoblasts in vitro, therefore they can be used as the seed cells for the tissue engineering. HSV-1 can infect rat BMSCs and develop the latent infection in vitro.

Objective To explore epithelial ovarian cancer(EOC)antigens that are potentially useful for cancer early detection and therapy.Methods A high quality cDNA library derived from ascites tumor cells of EOC patients(3 cases of serous EOC,1 case of mucinous EOC,and 1 case of endometrial carcinoma of ovary)was constructed,and the method of combining serological analysis of recombinant cDNA expression libraries(SEREX)and suppression subtractive hybridization(SSH)was used for screening cDNA library.All of the positive clones were sequenced and bioinformatics analysis with BLAST software in GenBank was performed.Serological mini-arrays of recombinant tumor antigens(SMARTA)was used to investigate the prevalence of autoantibodies to these antigens in both 96 ovarian cancer patients and 96 cancer-free controls.Results Fifty-five positive clones encoding different antigenic genes of EOC recognized by IgG and(or)IgM were obtained.It showed that these 55 clones derived from 45 distinct genes and these genes could be grouped into 6 classes as following according to homology with known expressed sequence tag(EST):(1)known ovarian carcinoma related genes:BARD1,et al;(2)homologous genes with other tumors:TM4SF1,et al;(3)homologous genes with special tissues:ILF3,FXR1,et al;(4) homologous genes with special function:TIZ,C1 D,et al;(5)embryo originating genes:PKHD1,et al; (6)novel genes:OV-189,et al.SMARTA results showed that the positive ratio of five EOC antigens TM4SF1(28% vs 9%),CID(21% vs 6%),BARD1(23% vs 5%),FXR1(23% vs 8%),OV-189 (31% vs 13%)which reacting with their IgG autoantibodies,three antigens TIZ(26% vs 8%),FXR1 (28% vs 11%),and OV-189(18% vs 7%)which reacting with their IgM autoantibodies in patients was higher than in controls(P

OBJECTIVETo establish a predictive scoring system which may serve for the prediction of sustained response to conventional interferon-alpha (IFN-alpha) treatment on chronic hepatitis B.

METHODSA total of 474 IFN-alpha treated hepatitis B virus e antigen (HBeAg)-positive patients were enrolled in the present study. The patients' baseline characteristics, such as age, gender, aminotransferases, activity grading (G) of intrahepatic inflammation, score (S) of liver fibrosis, hepatitis B virus (HBV) DNA and genotype were evaluated; therapy duration and response of each patient at the 24th wk after cessation of IFN-alpha treatment were also recorded. A predictive scoring system for a sustained complete response (CR) to IFN-alpha therapy was established based on genetic algorithm. About 10% of the patients were randomly drawn out as the test set. Responses to IFN-alpha therapy were divided into CR, partial response (PR) and non-response (NR). The mixed set of PR and NR was recorded as PR + NR.

RESULTSFor the scoring system, the sensitivity and specificity were 78.8% and 80.6%, respectively.

CONCLUSIONThis SCR scoring system has satisfying prediction efficiency and is easily employed in clinical practice. With this scoring system, practitioners can propose individualized decisions that have an integrated foundation on both evidence-based medicine and personal characteristics.

To investigate the relationship between socs3 mRNA expression and jak2v617f point mutation in bcr-abl negative patients with myelo-proliferative disease (MPD), 62 bcr-abl negative MPD patients (26 cases of PV, 26 cases of ET, 9 cases of IMF, and one case of CNL) were arranged as experiment group, and the others (20 cases of CML, 10 cases of AL and 15 healthy volunteers) were arranged as control group. All the diagnosis had been made according to the 2001 WHO criteria. jak2v617f point mutation was detected by AS-PCR and confirmed by direct sequencing. The expression level of socs3 mRNA was measured by RT-PCR. The association jak2v617f point mutation with socs3 mRNA expression in bcr-abl negative MPD patients was observed and analyzed. The results showed that among 62 bcr-abl negative MPD patients, the somatic jak2v617f point mutation was positive in 44 patients (PV 23, ET 15, IMF 5, CNL 1) while negative in the other 18 patients and control group. The expression of socs3 mRNA could be detected in 39 patients from 44 jak2v617f mutation positive patients and in 10 patients from 18 jak2v617f mutation-negative patients. There was a statistically significant difference in socs3 mRNA expression rates between jak2v617f mutation positive and negative group (chi(2) = 8.44, p < 0.005). There was a statistically significant difference in socs3 mRNA expression levels between jak2v617f mutation positive and negative groups (p = 0.035). It is concluded that there is a statistically significant difference in the expression level of socs3 mRNA in the patients between jak2v617f mutation positive group and negative group.

Peanut yield and quality are seriously affected by pod rot pathogens worldwide, especially in China in recent years. The goals of this study are to analyze the structure of fungal communities of peanut pod rot in soil in three peanut cultivars and the correlation of pod rot with environmental variables using 454 pyrosequencing. A total of 46,723 internal transcribed spacer high-quality sequences were obtained and grouped into 1,706 operational taxonomic units at the 97% similarity cut-off level. The coverage, rank abundance, and the Chao 1 and Shannon diversity indices of the operational taxonomic units were analyzed. Members of the phylum Ascomycota were dominant, such as Fusarium, Chaetomium, Alternaria, and Sordariomycetes, followed by Basidiomycota. The results of the heatmap and redundancy analysis revealed significant variation in the composition of the fungal community among the three cultivar samples. The environmental conditions in different peanut cultivars may also influence on the structure of the fungal community. The results of this study suggest that the causal agent of peanut pod rot may be more complex, and cultivars and environmental conditions are both important contributors to the community structure of peanut pod rot fungi.

OBJECTIVETo study the relationship between cadmium pollution and its adverse effects on female reproductive health status in people living in cadmium polluted area in Zhenghe, Fujian provinces.

METHODSData through laboratory studies on reproductive health of female residents in Cd-pollution area were studied and compared with those in control areas in Zhenghe.

RESULTSBoth prevalence rates of abnormal menstrual cycle and dysmenorrhea in unmarried women in Cd-pollution area (19.1% vs. 42.6%) were significantly higher than those in control area (5.7% vs. 18.9%) and the rates of sterility in married women in Cd-pollution area (6.3%) were significantly higher than those in control area (1.1%). During the first two pregnancies, rates of queasiness, disgorgement, spontaneous abortion and stillbirth in married women in polluted area were 44.7%, 31.7%, 10.27% and 4.23%, significantly higher than those 26.5%, 17.8%, 2.85% and 1.05% in control area, with significant differences (P < 0.05). Results from cumulative odds model analysis showed that: living in Cd-pollution area was a possible risk factor related to female reproductive health (OR = 2.072), after the other risk factors being under control.

CONCLUSIONThe female reproductive health status of people residing in the cadmium polluted area had already been deteriorated.

Objective:To compare the effect of two vs one stitch on outcomes in women with cervical incompetence who undergo emergency transvaginal cervical cerclage.Methods:A retrospective study was conducted on 38 cases of cervical incompetence patients who underwent emergency cervical cerclage at Fujian Maternity and Child Health Hospital from January 2018 to December 2022. These subjects were divided into two groups: one stitch group (loop continuous suture and knot at cervical-vaginal junction level) and two stitches group (the first loop was closed with a single suture set, and the second loop was closed below the first loop near the cervical outlet) with 19 cases in each group. Two independent samples t or t'-test, rank-sum test, Chi-square test and Fisher's exact test were used to compare the differences in perinatal outcomes between the two groups. Kaplan-Meier survival analysis was performed to evaluate the efficacy of the prolongation of gestational age after emergency transvaginal cervical cerclage. Results:There was no statistically significant difference in the gestational age at cervical cerclage between the two stitches and the one stitch group [24.9 weeks (23.9-25.9 weeks) vs 23.6 weeks (22.6-24.9 weeks), Z=－1.61, P=0.108]. The average gestational age at delivery [(33.1±4.8) vs (28.6±4.3) weeks, t=－3.10] and the prolongation of gestational age after cerclage[(8.5±4.6) vs (5.0±2.6) weeks, t=－2.90] were significantly greater in the two stitches group compared to those in the one stitch group, while the rates of preterm birth before 32 weeks (6/19 vs 16/19, χ2=10.80), 34 weeks (8/19 vs 17/19, χ2=9.47), and 37 weeks (14/19 vs 19/19, Fisher's exact test) were lower (all P<0.05). The Kaplan-Meier survival analysis demonstrated that the two stitches group had significantly higher efficacy in prolonging gestational age compared to the one stitch group [log-rank test χ2 (1)=13.10, P<0.05]. Although there was no statistically significant difference in the neonatal mortality between the two groups (2/19 vs 4/19, Fisher's exact test, P=0.660), survival neonates in the two stitches group had significantly higher birth weight [2 370.0 g (1 775.0-2 710.0 g) vs 1 300.0 g (1 210.0-1 660.0 g), Z=－3.14], lower admission rate to the neonatal intensive care unit (9/17 vs 15/15, Fisher's exact test), lower incidence of stage Ⅲ necrotizing enterocolitis (0/17 vs 5/15, Fisher's exact test), moderate-severe respiratory distress syndrome (5/17 vs 10/15, χ2=4.44), and grade Ⅲ-Ⅳ intraventricular hemorrhage (0/17 vs 7/15, Fisher's exact test) compared to those in the one stitch group (all P<0.05). Conclusion:Compared with emergency cervical cerclage with one stitch, the procedure with two stitches can prolong the gestational age and improve the neonatal prognosis more effectively.

Objective:To explore the clinical efficacy of ultrasound-indicated cervical cerclage in twin pregnancies.Methods:This retrospective cohort study included 96 asymptomatic twin pregnancies with cervix length (CL)≤2.5 cm at 16-27 +6 weeks indicated by transvaginal ultrasound from January 2013 to May 2022 in Fujian Maternity and Child Health Hospital. They received either cervical cerclage (cerclage group, n=45) or conservative treatment (conservative group, n=51). The subgroup analysis was further performed after stratifying the subjects into the CL≤1.0 cm subgroup, the CL>1.0-≤1.5 cm subgroup, and the CL>1.5 cm subgroup. Two independent samples t-test, Mann-Whitney U test, and Chi-square test were used to compare the differences in the pregnancy and perinatal outcomes between different groups. Multivariate logistic regression was used to analyze the impact of cervical cerclage on pregnancy outcomes of women with different CLs. Results:The average gestational age at delivery and the prolonged gestation were significantly greater in the cerclage group than those in the conservative group [35.9 (34.9-37.0) weeks vs 34.9 (29.1-36.1) weeks; 10.7 (9.6-13.1) weeks vs 8.7 (4.8-11.0) weeks, Z=－2.59 and -3.63, both P<0.05]. The incidences of preterm birth before 34 weeks and 28 weeks, chorioamnionitis, and preterm premature rupture of membrane were lower in the cerclage group than those in the conservative group [17.8% (8/45) vs 45.1% (23/51), χ2=8.16; 2.2% (1/45) vs 15.7% (8/51), Fisher' exact test; 8.9% (4/45) vs 25.5% (13/51), χ2=4.52; 15.6% (7/45) vs 33.3% (17/51), χ2=4.03; all P<0.05]. There were no statistically significant differences in the proportion of postpartum hemorrhage and live births between the two groups (both P>0.05). In the women with CL≤1.0 cm, the cerclage group had a greater gestational age at delivery [36.0 (34.8-37.3) weeks vs 34.9 (28.6-35.4) weeks, Z=－2.61, P=0.009], greater prolonged gestation [12.3 (9.7-13.9) weeks vs 7.3 (3.4-9.1) weeks, Z=－3.34, P=0.001], higher birthweight [2 430.0 (2 173.8-2 646.3) g vs 1 900.0 (1 372.5-2 435.0) g, Z=－3.06, P=0.002], lower incidence of adverse neonatal outcomes [16.7% (6/36) vs 36.7% (11/30), χ2=4.22, P=0.048] compared with the conservative group. Multivariate Logistic regression analysis showed that cerclage reduced the risks of preterm birth before 34 and 32 weeks [ aOR (95% CI)=0.083 (0.009-0.790) and 0.092 (0.009-0.939), both P<0.05]. However, cerclage did not reduce the risk of preterm birth in women with CL>1.5 cm or CL>1.0-≤1.5 cm (both P>0.05). Conclusion:Ultrasound- indicated cervical cerclage can reduce the risk of preterm birth before 34 and 32 weeks, prolong pregnancy, and improve perinatal outcomes in asymptomatic twin pregnancies with CL≤1.0 cm.

Objective:To investigate the incidence and risk factors associated with preterm premature rupture of membranes (PPROM) following transvaginal cervical cerclage.Methods:This retrospective cohort study involved 170 singleton pregnancies with cervical incompetence who underwent vaginal cervical cerclage at Fujian Maternity and Child Health Hospital from January 2021 to January 2022. Based on the onset of PPROM after cervical cerclage, the patients were divided into the PPROM group ( n=28) and the non-PPROM group ( n=142). Independent samples t-test, rank-sum test, Chi-square test, or Fisher's exact test were used to compare the general condition, pre- and postoperative data, pregnancy complications or comorbidities between the two groups, with a significance level at α=0.1. Multiple logistic regression analysis was conducted to identify the risk factors for PPROM after cerclage surgery. Results:The overall incidence of PPROM after vaginal cervical cerclage was 16.5% (28/170). Logistic regression analysis showed that a history of cervical conization ( OR=11.966, 95% CI:1.695-84.468), the use of Mersilene RS22 tape as the suture material ( OR=3.318, 95% CI:1.064-9.252), cervical length<2.5 cm after cerclage ( OR=3.486, 95% CI:1.116-10.888), and Mycoplasma genitalium- positive results for cervical secretion culture after surgery ( OR=4.856, 95% CI:1.487-15.861) were the independent risk factors for PPROM after cervical cerclage (all P<0.05). Conclusions:The incidence of PPROM following vaginal cervical cerclage is relatively high and can have unfavorable effects on pregnancy outcomes. Factors such as a history of cervical conization, the use of Mersilene RS22 tape for cerclage, cervical length<2.5 cm after cerclage, and Mycoplasma genitalium-positive results for cervical secretion culture after surgery may increase the risk of PPROM after cerclage.
