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.

Objective: To compare the immunogenicity of three kinds immunization programs with poliovirus vaccine. Methods: Healthy infants aged 2 months or over were selected and divided into three groups by complete randomization method. Basic immunization with Sabin inactivated poliovirus vaccine(sIPV) and bivalent oral poliovirus vaccine(bOPV) were completed. Three kinds of basic immunization procedures were 1sIPV+2bOPV,2sIPV+1bOPV and 3sIPV, respectively.Two qualified serums that before basic immunization and 28-42 days later were collected, and measured the poliovirus neutralizing antibody with microcell neutralization method. To compare the difference by analysis of variance, rank test and χ² test. Results: After the basic immunization, 205 subjects of the positive conversion rate of poliovirus neutralizing antibodies of types Ⅰ, Ⅱ and Ⅲwere all higher than 97.00%, and the positive rates were all higher than 98.00%, the geometric mean titer (GMT) of neutralizing antibody was significantly higher than that before basic immunization in three groups.There were significant differences in the positive rate and GMT before and after basic immunization of typeⅠ, Ⅱand Ⅲ in the three (P<0.05). The highest GMT in three groups after basic immunization were all typeⅠ, followed by type Ⅲ, and the lowest in type Ⅱ. The GMT of type Ⅱin 2sIPV+1bOPV and 3sIPV groups were both higher than that in sIPV+2bOPV group. Conclution: After three kinds of basic immunization, the poliovirus neutralizing antibodies of serum were all at high levels in three groups, which could form an effective immune barrier against poliovirus. The immunogenicity of three kinds of basic immunization programs were all well, but there were certain differences of neutralizing antibodies among three kinds basic immunization programs. The immunogenicity in 2sIPV+1bOPV and 3sIPV groups against typeⅡpoliovirus were better than that in 1sIPV+2bOPV group.

OBJECTIVE: To explore the effect of dihydromyricetin on the expression of miR-98-5p and its mechanism in the development of Herceptin resistance in SKBR3 cells. METHODS: The expression of IGF2 and miR-98-5p and their interaction relationship were analyzed by bioinformatics analysis through TargetScan online databases. SKBR3 cells and drug-resistant SKBR3-R cells were cultured in cell experiments. Xenograft tumor mice were constructed by SKBR3 and SKBR3-R cells. Proteins were detected by western blotting and immunohistochemistry. Transfected cells were constructed by shRNA lentivirus vectors. RT-QPCR was used to detect RNA. Cell proliferation was detected by MTS method. Cell jnvasion was detected by Transwell assay. Luciferase reporting assays were used to verify RNA interactions. IGF-1R/HER2 heterodimer was determined by immunocoprecipitation. RESULTS: The expression of IGF2, p-IGF1R, p-Akt and p-S6K in SKBR3-R cells were significantly higher than those in SKBR3 cells, while the expression of PTEN protein was lower in SKBR3-R cells (P < 0.05). IGF1R/HER2 heterodimer in SKBR3-R cells was significantly increased (P < 0.01).The expression of IGF2 and invasion ability were significantly reduced while transfected with miR-98-5p in SKBR3-R cells (P < 0.05), but the IGF2 mRNA were no difference in both cells (P > 0.05). The expression of miR-98-5p was up-regulated and IGF2 was decreased in drug-resistant xenograft tumor mice after feeding with dihydromyricetin, and the tumor became more sensitivity to Herceptin (P < 0.05). CONCLUSION Dihydromyricetin could induce the expression of miR-98-5p, which binds to IGF2 mRNA to reduce IGF2 expression, inhibit the IGF-1R/HER2 formation, thereby reversing cell resistance to Herceptin in SKBR3-R cells.

Objective: To investigate the impact of parental conflict perception on adolescent anxiety and the therapeutic effect of family therapy on adolescent anxiety. Methods: A total of 120 adolescent anxiety patients who attend the psychological clinic of the fourth renming hospital in Hefei were selected and were divided into two groups, the treatment group and control group, impact clinical medication while the treatment group recevied both clinical medication and family therapy(for three months). Parents Conflict Consciousness Scale(CPIC), Hamilton Anxiety Scale (HAMA) was used to assess parents conflict consciousness of adolescent anxiety. Effects of family therapy on teenagers anxiety and CPIC, HAMA score were analyzed. Results: CPIC conflict intensity, threats of cognitive conflict and content for adolescent anxiety were positively correlated with HAMA scores(r=0.26, 0.20, 0.18, P<0.05), At the end of the three-month treatment, the score on HAMA and CPIC of the treatment group (HAMA: 9.23±1.98, CPIC: 9.52±2.35) was significantly lower than that of the control group(HAMA: 14.52±2.66, CPIC:11.98±2.55)(t=11.88, 5.48, P<0.01). HAMA and CPIC scores of patients in both groups significantly decreased compared to before treatment(control group t=13.88, 16.84; treatment group t=20.50, 21.89, P<0.01). Conclusion Parental conflict perception shows impact on adolescent anxiety, and family therapy can reduce parental conflict perception and relieve adolescent anxiety.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Objective: The study aims to predict 10-year cardiovascular disease (CVD) risk and explore its association with sleep duration among Chinese urban adults. Methods: We analyzed part of the baseline data of a cohort that recruited adults for health screening by cluster sampling. The simplified Pittsburgh Sleep Quality Index (PSQI) and Framingham 10-year risk score (FRS) were used to measure sleep duration and CVD risk. Demographic characteristics, personal history of chronic diseases, lifestyle factors were collected using a questionnaire. Height, weight, total cholesterol (TC), and high-density lipoprotein cholesterol (HDL-C) were also measured. Multiple logistic regression models were performed to explore the association of sleep duration with the predicted CVD risk. Results: We included 31, 135 participants (median age 44 years, 53.02% males) free of CVD, cerebral stroke, and not taking lipid-lowering agents. Overall, 14.05%, and 25.55% of participants were at medium and high predicted CVD risk, respectively. Short sleep was independently associated with increased odds of medium to high risk of predicted 10-year CVD among males ( Conclusion A substantial number of adults free of CVD were at high 10-year CVD risk. Short sleep was associated with increased odds of predicted CVD risk.

Obstructive sleep apnea (OSA) may increase the risk of stroke, and patients with stroke are also prone to suffer OSA. Advanced age, high body mass index, male, hypertension and diabetes are risk factors for stoke in OSA patients, and severe sleep apnea may also be associated with poor functional outcomes of stroke. Potential pathophysiological mechanisms may include endothelial dysfunction, abnormal neuromodulation, metabolic abnormalities, change of cerebral hemodynamic and hypercoagulability. Continuous positive airway pressure (CPAP) is the standard treatment for patients with moderate to severe OSA, but it has not been proved that CPAP can reduce the risk of cardiovascular events including stroke.

Objective: To explore the effect of Feng-liao-chang-wei-kang (FLCWK) on acute and chronic gastroenteritis, synergistic effect on the growth inhibitory effect with 5-fluorouracil (5-FU) on colorectal cancer and its underlying mechanisms. Methods: In the in vitro study, HT-29 cells were divided into 5-FU alone, FLCWK alone and coadministration groups. The MTT assay was used to analyze the proliferation of HT-29 cells at 24 h. Flow cytometry was used to observe the apoptosis, cycle of colorectal cancer HT-29 cells at 24 h. In the in vivo experiment, The subcutaneous transplantation tumor model of colorectal cancer HT-29-Luc was established with nude mice. All mice were randomly divided into 5-FU alone, FLCWK alone and coadministration groups according to body weight. During administration, the Interactive Video Information System small animal live imaging system was used to monitor the growth of subcutaneous transplantation in nude mice. The model of colitis-associated colorectal cancer (CACC) was established with BALB/c mice. BALB/c mice were randomly divided into the normal control group, the model control group, and the FLCWK group. At the end of the administration, the pathological status was detected by HE staining. Cell apoptosis of tumor tissue tumor and colon tissues were observed by TUNEL staining and TUNEL green fluorescence. The protein expression of Caspase 3, p-STAT3, Bcl-2, Bax and P-gp in tumor tissues tumor and colon tissues were tested by using immunohistochemical assay. Results: FLCWK and 5-FU coadministration suppressed HT-29 cell viability and induced S phase arrest and apoptosis compared to treatment with 5-FU alone. Furthermore, compared to treatment with 5-FU alone, coadministration of FLCWK and 5-FU obviously reduced tumor volume and weight and induced apoptosis through decreasing p-STAT3 and P-gp and increasing Caspase 3 protein expression in a murine xenograft tumor model. Moreover, the result revealed decreased number and size of tumors following FLCWK protective administration, downregulated p-STAT3 and Bcl-2 levels and upregulated Bax and Caspase 3 expression in mice with CACC. Conclusions: FLCWK has synergistic effects with 5-FU on colorectal cancer by suppressing the STAT3 pathway and downregulating P-gp expression. Furthermore, FLCWK administration suppresses CACC tumorigenesis by inhibiting the STAT3 pathway.
