ObjectiveTo investigate the regulatory effect of Shoutaiwan on oxidative stress and pyroptosis in lipopolysaccharide （LPS）-induced human extravillous trophoblast （HTR-8/SVneo） cells and provide a new direction for deciphering the mechanism of action of Shoutaiwan. MethodLPS （100 μg∙L^-1） was used to induce the injury of HTR-8/SVneo cells （modeling）. Five groups were designed in this study， including a blank group， a model group， a Shoutaiwan （10% Shoutaiwan-containing serum） group， an antioxidant （1 mmol·L^-1 NAC） group， and NOD like receptor thermoprotein domain 3 （NLRP3） inhibitor （50 μmol·L^-1 MCC950） group. Cell viability was detected by cell counting kit-8 （CCK-8） kit. Hochest 33342/PI double fluorescence staining and flow cytometry were employed to observe cell death. The levels of interleukin-18 （IL-18）， interleukin-1β （IL-1β）， malondialdehyde （MDA）， and superoxide dismutase （SOD） in cell supernatant was determined by enzyme-linked immunosorbent assay （ELISA）. DCFH-DA probe was used to measure the level of intracellular reactive oxygen species （ROS）. Western blot was employed to determine the protein levels of NLRP3， Caspase-1， gastermin D （GSDMD）， and IL-1β in cells， and Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） to measure the mRNA levels of NLRP3 and Caspase-1 in cells. ResultCompared with the blank group， the modeling decreased the cell viability （P<0.01）， elevated the levels of IL-1β， IL-18， ROS， and MDA， and weakened the activity of SOD （P<0.01）. Furthermore， it up-regulated the protein levels of NLRP3， Caspase-1， GSDMD， and IL-1β and the mRNA levels of NLRP3 and Caspase-1 （P<0.01）. Compared with the model group， Shoutaiwan， NAC， and MCC950 increased the cell viability （P<0.01）. Further， Shoutaiwan and NAC lowered the levels of MDA and ROS and increased the activity of SOD （P<0.01）. Shoutaiwan and MCC950 reduced the IL-1β and IL-18 in cell supernatant （P<0.01）， and down-regulated the protein levels of NLRP3， Caspase-1， GSDMD， and IL-1β and the mRNA levels of NLRP3， Caspase-1， and IL-1β （P<0.05，P<0.01）. ConclusionShoutaiwan can regulate oxidative stress and pyroptosis to attenuate the LPS-induced damage of HTR-8/SVneo cells， which may be the mechanism of Shoutaiwan in preventing recurrent spontaneous abortion.

Objective: To explore the association between self-reported gingival bleeding and prevalent hypertension among adults in Zhejiang with a cross-sectional study. Methods: After excluding participants with self-reported, physician-diagnosed heart diseases, stroke, diabetes, cancer, and those who never or rarely brush their teeth at baseline study, 48 625 participants aged 30-79 in the China Kadoorie Biobank (CKB) study from Tongxiang, Zhejiang were included for the final analysis. Three multivariable logistic regression models were used to estimate the odds ratios (ORs) for the associations of self-reported gingival bleeding with prevalent hypertension. Results: The mean age of women was (51.2±9.2) years, and 42.9% of participants had prevalent hypertension. The percentage of self-reported frequent gingival bleeding was 6.56% (95%CI: 6.38%-6.75%), significantly higher among women (8.08%, 95%CI: 7.82%-8.35%) than among men (4.36%, 95%CI: 4.12%-4.60%) (P<0.001). After adjusting for socio-demographic factors, behavioral lifestyle, sleep duration, BMI, waist circumference, snoring, in comparison with men whose gingivae never or rarely bleed while brushing teeth, the odds ratio (95%CI) of hypertension for those with occasional, and frequent gingival bleeding were 1.04 (0.96-1.12) and 1.18 (1.02-1.37), respectively (trend P =0.038). The corresponding figures for women were 0.96 (0.91-1.02) and 0.95 (0.86-1.05), respectively (trend P=0.344). Conclusion: Frequent gingival bleeding was positively associated with prevalent hypertension among men.

Objective:To observe the effects of Huluan decoction on the expression of apoptosis-related protein silence information regulator 1 （SIRT1）， tumor suppressor gene （p53）， acetylated p53 （Ac-p53）， cyclin-dependent kinase inhibitor （p21）， and nuclear factor-κB （NF-κB） p65 and changes in ovarian tissue structure of a mouse model with premature ovarian insufficiency （POI） induced by tripterygium glycosides. Method:Fifty female C57BL/6J mice were randomly divided into the blank group， model group， low- and high-dose Huluan decoction groups， and western medicine （estradiol valerate） group. After intragastric administration of tripterygium glycosides at 80 mg·kg^-1·d^-1 for 14 successive days， mice in the low- and high-dose Huluan decoction groups and western medicine group were treated with Huluan decoction at 1.6 g·kg^-1·d^-1 and 6.2 g·kg^-1·d^-1 and estradiol valerate at 0.13 mg·kg^-1·d^-1， respectively， by gavage since the 15^th day， while those in the blank group were provided with an equal amount of distilled water for 21 consecutive days. Following the last administration， the blood was sampled for detecting the levels of serum anti-Müllerian hormone （AMH）， follicle-stimulating hormone （FSH）， and luteinizing hormone （LH） by ELISA and the ovary was harvested for observing the morphological changes by HE staining. The mRNA expression levels of p53 and p21 were measured by Real-time polymerase chain reaction （Real-time PCR）， and the protein expression levels of SIRT1， p53， p21， Ac-p53， NF-κB were assayed by Western blot. Result:Compared with the blank group， the model group exhibited a disordered estrous cycle， diminished ovarian volume， decreased number of follicles at various developmental stages， reduced AMH， and elevated FSH and LH， and elevated p53，p21，Ac-p53，NF-κB protein expression and p53，p21 mRNA， reduced SIRT1 protein expression（P<0.01）. As revealed by the comparison with the model group， each medication group displayed an increased number of follicles， elevated AMH， reduced FSH and LH （P<0.01）， up-regulated SIRT1 protein expression （P<0.01）， and significantly down-regulated mRNA and protein expression of aging-related genes p53， p21， and down-regulated Ac-p53，NF-κB protein expression （P<0.01）. Conclusion:Huluan decoction significantly reverses the aging process and improves ovarian function possibly by boosting the activity of SIRT1/NF-κB/p53/p21 pathway in ovarian cells， changing the apoptotic state， increasing the growing and mature follicles， and reducing the atretic follicles.

Objective:To explore the association between snoring and prevalent hypertension among adults in Zhejiang with a cross-sectional study.Methods:After excluding participants with self-reported, physician-diagnosed heart diseases, stroke and cancer at baseline study, 56 728 participants aged 30-79 in the China Kadoorie Biobank study from Tongxiang, Zhejiang were included for the final analysis. Three multivariable logistic regression models were used to estimate the ORs for the associations of snoring with prevalent hypertension. Results:The proportion of participants who snored frequently, snored sometimes, and never snored were 24.55%, 23.94%, and 51.51%, respectively. The corresponding figures of males were 32.40%, 26.55%, and 41.05%, respectively. The corresponding figures of females were 19.00%, 22.08%, and 58.92%, respectively ( P<0.001). After adjusted socio-demographic factors, behavioral lifestyle, BMI, waist circumference, and sleep duration etc., in comparison with participants who never snored, the odds ratios (95% CI) of hypertension for those who snored frequently and snored sometimes were 1.17 (1.12-1.23) and 1.12 (1.07-1.18), respectively. The effects of snoring on hypertension were statistically significantly different between women and men, participants who were central obese and those who were not, and between premenopausal and post-menopausal women. Conclusion:Snoring was associated positively with hypertension among adults. The effect of snoring on prevalent hypertension were obvious, especially among people, being female, being central obese, and being premenopausal.
