ObjectiveTo investigate the protective effect and mechanism of action of flavonoid combination of Alpiniae Officinarum Rhizoma （A. officinarum） against Helicobacter pylori （H. pylori） gastritis in mice. MethodsAfter acclimatization for one week， 56 SPF-grade healthy C57BL/6J mice were gavaged with mixed antibiotics for three consecutive days. They were randomly divided into a normal group， model group， positive drug group （triple therapy group）， and low- and high-dose groups （100， 200 mg·kg^-1） of flavonoid combination of A. officinarum. The H. pylori gastritis mice model was established by gavage with H. pylori bacterial suspension in each group except for the normal group. After successful modeling， mice were administrated with corresponding drugs once a day for two weeks. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in gastric tissue. Rapid urease test paper was used to detect the positive rate of H. pylori. Silver staining was used to observe the H. pylori adherence on the surface of gastric tissue. Immunohistochemistry was used to detect the protein expression of interleukin-8 （IL）-8 and myeloid differentiation factor （MyD88） in gastric tissue. The serum levels of IL-6， tumor necrosis factor-α （TNF-α）， IL-8， and IL-1β were detected by enzyme-linked immunosorbent assay （ELISA）. The expressions of phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） protein were detected by Western blot. ResultsCompared with those in the normal group， mice in the model group had lower gastric weight coefficients， higher pH of gastric juice， 100% H. pylori infection rate， and significantly changed gastric histopathology. The expressions of IL-8 and MyD88 proteins in the gastric tissue of mice in the model group were significantly elevated， and the serum levels of inflammatory factors IL-6， TNF-α， IL-8， and IL-1β were significantly up-regulated in mice. Compared with that in the model group， the gastric weight coefficient of mice in each treatment group of the flavonoid combinations of A. officinarum was elevated （P<0.01）， and the pH of gastric juice was reduced （P<0.01）. The infection rate of H. pylori was reduced. The expressions of IL-8 and MyD88 proteins in the gastric tissue of mice in the treatment groups were significantly reduced （P<0.01）， and the serum levels of inflammatory factors IL-6， TNF-α， IL-8， and IL-1β were significantly reduced in a dose-dependent manner （P<0.01）. The flavonoid combinations of A. officinarum down-regulated the expression of PI3K and Akt proteins in H. pylori gastritis-infected cells （P<0.01）. ConclusionThe protective effect of flavonoid combinations of A. officinarum against H. pylori gastritis is associated with the inhibition of H. pylori infection rate and regulation of PI3K/Akt signaling pathway， resulting in inhibiting the release of inflammatory factors.

Objective To screen the anti-Helicobacter pylori gastritis active components of the ethyl acetate extract of Alpinia officinarum Hance.Methods The"knock-out"strategy combined with high-performance liquid chromatography(HPLC)detection was developed to separate the components of the ethyl acetate extract of A.officinarum while obtaining the negative samples without the components.A human gastric epithelial cell(GES-1)model of H.pylori gastritis was established,and the levels of interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),interleukin-8(IL-8)and interleukin-1β(IL-1β)in the supernatant of the cells were determined by enzyme-linked immunosorbent assay(ELISA).Results The total flavonoid fraction,the negative fraction without total diphenylheptanoids,the negative fraction without 5-hydroxy-7-(4-hydroxy-3-methoxyphenyl)-1-phenyl-3-heptanone(DHPA),and galangin significantly reduced IL-6 levels in the supernatant of H.pylori infected GES-1 cells at a concentration of 8 μg·mL-1 with 24 h incubation.The total flavonoid fraction strongly inhibited the release of IL-6,TNF-α,IL-8,and IL-1β from H.pylori gastritis GES-1 cells at a concentration of 16 μg·mL-1.Conclusions The total flavonoid fraction is the major anti-H.pylori gastritis active component of the ethyl acetate extract of A.officinarum.The results lay the foundation for further elucidation of the material basis of A.officnarum against H.pylori gastritis.

Objective:To investigate the value and clinical significance of fasting plasma glucose (FPG) in early pregnancy (8-12 gestational weeks) as a predictor of gestational diabetes mellitus (GDM) among women with different pre-pregnancy body mass index (pre-BMI) categories.Methods:A retrospective study was conducted including 9 710 singleton pregnant women (FPG levels in early pregnancy ≤5.6 mmol/L) who underwent prenatal screening and delivery in Yuyao People's Hospital from January 2020 to December 2022. Participants were stratified based on their pre-BMI as follows: <18.5 ( n=1 406), ≥18.5 to <25.0 ( n=7 162), ≥25.0 to <30.0 ( n=978), and ≥30.0 kg/m 2 ( n=164). Within each pre-BMI category, women were further divided into four groups based on FPG levels in early pregnancy (<4.5, ≥4.5 to <4.8, ≥4.8 to <5.1, and ≥5.1 mmol/L). Univariate and multivariate logistic regression analysis were used to identify risk factors for GDM, and receiver operating characteristic (ROC) curve was applied to evaluate the efficacy of FPG in early pregnancy based on different pre-BMI in predicting GDM. Results:The overall incidence of GDM in the singleton pregnancy women with FPG levels in early pregnancy ≤5.6 mmol/L was 12.3% (1 197/9 710). For a pre-BMI of <18.5 kg/m 2, the ORs with 95% CIs for GDM within the different FPG categories (<4.5, ≥4.5 to <4.8, ≥4.8 to <5.1, and ≥5.1 mmol/L) were 0.041 (95% CI: 0.015-0.409), 1.834 (95% CI: 1.089-3.088), 6.779 (95% CI: 4.041-11.371), and 13.723 (95% CI: 5.560-33.871), respectively. For pre-BMI of ≥18.5 to <25.0 kg/m 2, the respective the ORs with 95% CIs were 0.048 (95% CI: 0.012-0.203), 2.573 (95% CI: 2.091-3.168), 9.023 (95% CI: 7.240-11.245), and 9.158 (95% CI: 6.484-12.937). For pre-BMI of ≥25.0 to <30.0 kg/m 2, the ORs with 95% CIs were 0.108 (95% CI: 0.053-0.446), 1.698 (95% CI: 1.064-2.654), 7.537 (95% CI: 5.285-13.080), and 9.994 (95% CI: 5.613-18.218). For pre-BMI of ≥30.0 kg/m 2, the ORs with 95% CIs were 0.098 (95% CI: 0.072-1.015), 2.888 (95% CI: 0.911-9.157), 13.674 (95% CI: 3.480-53.736), and 20.509 (95% CI: 6.674-63.019). The optimal cutoff value of FPG in early pregnancy for GDM prediction was 4.7 mmol/L with an area under the curve of 0.752, the risk of GDM significantly increased with FPG levels ≥4.7 mmol/L in early pregnancy across all pregnant women ( OR=17.356, 95% CI: 13.757-21.896, P<0.001). Conclusions:In the singleton pregnancy women with FPG levels in early pregnancy ≤5.6 mmol/L, FPG in early pregnancy is an independent risk factor for the occurrence of GDM; for pregnant women stratified by the same pre-BMI, the risk of developing GDM increases progressively with the rise of FPG in early pregnancy. FPG in early pregnancy has a certain value in predicting the occurrence of GDM.

Objective:To investigate the clinical value of emergent endoscopic intervention at different times of acute esophageal and gastric fundal varices bleeding.Methods:From July 2020 to December 2022, data of 207 cases of liver cirrhosis with esophageal and gastric fundal variceal bleeding diagnosed by gastroscopy were retrospectively analyzed, including 74 cases from the Second Affiliated Hospital, Zhejiang University School of Medicine, 41 cases from Affiliated Jinhua Hospital, Zhejiang University School of Medicine, 36 cases from Lanxi People's Hospital, 31 cases from Yongkang First People's Hospital and 25 cases from Pujiang People's Hospital. Patients were divided into 3 groups according to the time of endoscopic intervention and treatment. Patients who received endoscopic treatment within 6 h of hemorrhage were included in group A ( n=68); patients within 6-24 hours were in group B ( n=72). A total of 67 patients selected for conservative drug treatment were included in group C, who did not undergo endoscopic therapy. The prognosis (success rate of hemostasis, early rebleeding rate, mortality rate) and treatment benefit (open diet time, blood transfusion volume, hospital stay, hospital cost) of the 3 groups were compared. Results:The success rates of hemostasis were 100.00% (68/68), 97.22% (70/72), 86.57% (58/67) in group A, B and C respectively with significant difference ( χ2=13.51, P<0.001). The mortalities of the three groups were 0.00% (0/68) in group A, 2.78% (2/72) in group B and 13.43% (9/67) in in group C respectively with significant difference ( χ2 =15.61, P<0.001). The early rebleeding rates of the three groups were 0.00% (0/68) in group A, 2.86% (2/70) in group B, and 13.43% (5/58) in group C respectively with significant difference ( χ2 =3.41, P=0.182). There were significant differences in open diet time (group A: 28.32 ±2.52 h, group B: 37.25±2.45 h, group C: 66.62±2.65 h, F=58.69, P<0.001), blood transfusion volume (group A: 3.62 ± 0.30 U, group B: 5.46 ± 0.37 U, group C: 6.25 ± 0.39 U, F=11.35, P<0.001), hospital stay (group A: 6.58 ± 0.23 d, group B: 7.83 ± 0.34 d, group C: 8.24 ± 0.45 d, F=5.75, P=0.004) and cost (group A: 10 152±821 yuan, group B: 13 568 ± 1 017 yuan, group C: 15 306 ± 1 186 yuan, F=4.96, P=0.008) among the three groups. There was significant difference in Child-Pugh grading among hemostasis-success patients and those who failed ( χ2 =15.63, P<0.001). Conclusion:Early endoscopic diagnosis and treatment in the early 24 hours of acute esophageal and gastric fundal variceal hemorrhage can improve the prognosis and reduce the economic burden of patients with high clinical application value.

Assisted vaginal delivery (AVD) and cesarean section are two delivery methods used to terminate abnormal labor, which may cause physiological and psychological trauma to the parturient women, thus affecting their daily life and even next pregnancy. In recent years, scholars at home and abroad have paid more and more attention to "birth trauma", but its definition is still unclear. In clinical practice, more attention should be paid to the physiological and psychological trauma caused by AVD and cesarean section, but there is still a lack of specific trauma prediction and assessment tools, resulting in insufficient prevention and diagnosis of birth trauma. The authors reviewed the research progress in physiological and psychological trauma of parturient women induced by AVD and cesarean section in order to provide further reference and new ideas for the prevention and treatment of birth trauma.

Objective:To investigate the value of transperineal ultrasound assessment of levator hiatal antero-posterior (LHap) diameter changes in the diagnosis of pelvic floor dysfunction.Methods:The clinical data of 246 patients with suspected pelvic floor dysfunction who received treatment in Yuyao People's Hospital of Zhejiang Province from October 2020 to June 2021 were retrospectively analyzed. All these patients underwent clinical examination and modified Oxford score (MOS) evaluation. They were divided into observation group (low pelvic floor muscle contractility) and control group (normal pelvic floor muscle contractility) according to MOS. All patients were subjected to ultrasound examination and LHap diameter measurement under three conditions (at rest, pelvic floor muscle contraction, and maximal Valsalva maneuver). The percentage of shortening of LHap diameter (PDC%) and the percentage of elongation of LHap diameter (PIV%) were calculated. The differences of PDC% and PIV% were compared between the observation and control groups. The receiver operating curve was used to evaluate the values of PDC% and PIV% in the diagnosis of pelvic floor dysfunction.Results:Age, body mass index, the proportion of parturient women among included patients, and the proportion of patients who underwent vaginal delivery were significantly higher in the observation group than those in the control group (all P < 0.001). LHap diameters measured when patients were at rest, pelvic floor muscle contraction, and maximal Valsalva maneuver as well as PIV% in the observation group were (45.23 ± 5.74) mm], (37.71 ± 8.44) mm, (51.03 ± 7.41) mm and (11.42 ± 4.79)%, respectively, which were significantly higher than those in the control group [(41.78 ± 4.56) mm, (29.15 ± 4.64) mm, (44.28 ± 4.87) mm, (6.05 ± 2.13)%, t = -4.62, -8.29, -7.26, -9.36, all P < 0.001]. PDC% in the observation group was significantly lower than that in the control group [(17.52 ± 5.58)% vs. (32.19 ± 4.27)%, t = 20.39, P < 0.001]. MOS was positively correlated with PDC% ( r = 0.56, P < 0.001) and it was negatively correlated with PIV% ( r = -0.49, P < 0.001). Taking PDC% < 35.36% as the cut-off value, the area under the receiver operating curve was 0.85, the sensitivity, specificity and accuracy values were 66.40%, 97.38%, and 73.90%, respectively. Taking PIV% > 5.18% as the cut-off value, the area under the curve was 0.70, and the sensitivity, specificity and accuracy values were 71.45%, 57.90% and 68.15%, respectively. When PDC% and PIV% were used together, the area under the curve was 0.73 and the sensitivity, specificity and accuracy values were 84.57%, 55.05% and 77.32%, respectively. Conclusion:Transperineal ultrasound assessment of LHap diameter changes are of certain value in the prediction of pelvic floor dysfunction and can provide objective and quantitative data support for clinicians to diagnose pelvic floor dysfunction. This study is highly innovative and scientific.

Objective:To investigatethe maternal and infant adverse outcomes of group B streptococcus (GBS) colonization during the late pregnancy.Methods:A total of 567 pregnant women who underwent obstetrics and gynecology examination in Yuyao People′s Hospital from December 2018 to June 2019 were selected for the study. Internal vaginal secretions of all the pregnant women were extracted from the lower 1/3 of the vagina for bacterial culture, and GBS culture and screening were performed on pregnant women. According to the results of GBS screening, pregnant women were divided into GBS negative group (8 cases) and GBS positive group (559 cases). The general condition and pregnancy outcomes of pregnant women were compared between the two groups, and the correlation between pregnancy outcomes and streptococcus colonization was analyzed.Results:There were no statistically significant differences in age, gestational weeks, number of births, number of pregnancies, history of abortion, residence area and ethnicity between the two groups ( P>0.05). The incidence of premature rupture of membranes and fetal distress in GBS positive group were higher than those in GBS negative group:5/8 vs. 7.69%(43/559), 3/8 vs. 5.01%(28/559), and the differences were statistically significant ( P<0.05). Spearman single factor correlation analysis showed that GBS colonization in pregnant women were positively correlated with premature rupture of membranes and fetal distress ( r = 0.632, 0.573, P<0.05). Conclusions:GBS colonization in late pregnancy is closely related to pregnancy outcomes, and strengthening GBS screening has great significance to reduce adverse pregnancy outcomes.

Objective:To investigate the effects of growth hormone combined with triptoreline acetate on growth and sex hormone in girls with central precocious puberty.Methods:Sixty-two girls with central precocious puberty who received treatment in Xin'an International Hospital from January 2017 to December 2019 were included in this study. They were randomly assigned to receive treatment with either triptorelin acetate (control group, n = 31) or triptorelin acetate plus growth hormone (observation group, n = 31) for 12 successive months. Before and after treatment, bone age difference/chronological age difference (△BA/△CA), body height, body weight, uterine and ovarian volume and sex hormone level were compared between the control and observation groups. Results:△BA/△CA in the observation group was significantly lower than that in the control group [(0.64 ± 0.17) vs. (0.95 ± 0.13), t = 8.065, P < 0.05). Body height and weight in the observation group were (127.32 ± 1.08) cm and (33.42 ± 2.37) kg, respectively, which were significantly higher than those in the control group [(126.34 ± 0.87) cm and (31.01 ± 2.15) kg, t = 3.934 and 4.193, both P < 0.05]. Uterine and ovarian volume in the observation group were (1.68 ± 0.29) cm 3 and (1.26 ± 0.18) cm 3, respectively, which were significantly lower than those in the control group [(2.41 ± 0.46) cm 3 and (1.83 ± 0.26) cm 3, t = 7.474 and 10.036, both P < 0.05). After treatment, there were no significant differences in serum estradiol and luteinizing hormone levels between the two groups (both P > 0.05). Conclusion:Growth hormone combined with triptoreline acetate has a good effect on central precocious puberty in girls because it can improve the growth and development of girls and reduce serum levels of estradiol and luteinizing hormone.

Objective To discuss the safety and efficacy of inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture.Methods There was an retrospective analysis on operation videos and clinical data for 16 participants of inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture with the period from March in 2012 to September in 2015. And these were statistically analyzed including the operation time, intraoperative bleeding volume, postoperative drainage volume, removal time of drainage tube, admission time after operation and the incidence of postoperative complications of vesicoureteric reflux and stenosis.Results The operations of 16 participants were completed successfully without converting to open surgery. The operation time was 60 ~ 125 min (Mean time: 85 min); intraoperative bleeding volume was 20 ~ 50 ml (Mean volume: 32 ml); postoperative drainage volume was 60 ~ 400 ml (Mean volume: 106 ml); removal time of drainage tube was 3 ~ 6 d (Mean time: 4.2 d) and admission time after operation was 7 ~ 10 d (Mean time: 8.5 d). There was the follow-up with 6 ~ 18 months (Mean time: 12 months) for participants. No anastomotic stenosis was present. In addition, one participant was suffered from mild vesicoureteric relfux. And there was no aggravation during 18 months.Conclusions The inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture was safe and effective. It was found that the operation time was significantly shortened and the incidence of postoperative complications of vesicoureteric relfux and anastomotic stenosis was not increased. By contrast, the six-stitch suture could reduce the incidence of anastomotic stenosis.
