OBJECTIVE:
To observe the clinical efficacy of acupuncture on mild cognitive impairment (MCI) and its effect on gut microbiota.
METHODS:
A total of 62 MCI patients were randomly divided into an experimental group (31 cases, 2 cases dropped out) and a control group (31 cases). Both groups received exercise and cognitive training. In addition, the experimental group underwent acupuncture treatment at acupoints including Baihui (GV20), Sishencong (EX-HN1), and bilateral Fengchi (GB20), Xuanzhong (GB39), Zusanli (ST36), Yanglao (SI6), Xinshu (BL15), and etc., once every other day, three times per week, for a total of 12 weeks. Before and after treatment, the Montreal cognitive assessment (MoCA) and mini-mental state examination (MMSE) scores were evaluated in the two groups, changes in gut microbiota were detected using 16S rDNA sequencing technology. The clinical efficacy was assessed after treatment.
RESULTS:
Compared before treatment, MoCA and MMSE scores were increased in both groups after treatment (P<0.001), with higher scores in the experimental group than those in the control group (P<0.001, P<0.05). After treatment, the relative abundance of Faecalibacterium, Clostridia, and Ruminococcaceae was increased in the experimental group compared with that before treatment (P<0.05). Moreover, the relative abundance of Faecalibacterium in the experimental group was higher than that in the control group (P<0.05). The total effective rate was 82.8% (24/29) in the experimental group, which was higher than 61.3% (19/31) in the control group (P<0.05).
CONCLUSION
Acupuncture could improve cognitive dysfunction in patients with MCI, and its mechanism may be related to increasing the relative abundance of butyrate-producing bacteria such as Faecalibacterium, Clostridia, and Ruminococcaceae, maintaining the intestinal barrier, and inhibiting related inflammatory responses.

This study investigated the effects and underlying mechanisms of vanillic acid(VA) against cardiac fibrosis(CF) induced by isoproterenol(ISO) in mice. Male C57BL/6J mice were randomly divided into control group, VA group(100 mg·kg~(-1), ig), ISO group(10 mg·kg~(-1), sc), ISO + VA group(10 mg·kg~(-1), sc + 100 mg·kg~(-1), ig), ISO + dynamin-related protein 1(Drp1) inhibitor(Mdivi-1) group(10 mg·kg~(-1), sc + 50 mg·kg~(-1), ip), and ISO + VA + Mdivi-1 group(10 mg·kg~(-1), sc + 100 mg·kg~(-1), ig + 50 mg·kg~(-1), ip). The treatment groups received the corresponding medications once daily for 14 consecutive days. On the day after the last administration, cardiac functions were evaluated, and serum and cardiac tissue samples were collected. These samples were analyzed for serum aspartate aminotransferase(AST), lactate dehydrogenase(LDH), creatine kinase-MB(CK-MB), cardiac troponin I(cTnI), reactive oxygen species(ROS), interleukin(IL)-1β, IL-4, IL-6, IL-10, IL-18, and tumor necrosis factor-α(TNF-α) levels, as well as cardiac tissue catalase(CAT), glutathione(GSH), malondialdehyde(MDA), myeloperoxidase(MPO), superoxide dismutase(SOD), total antioxidant capacity(T-AOC) activities, and cytochrome C levels in mitochondria and cytoplasm. Hematoxylin-eosin, Masson, uranium acetate and lead citrate staining were used to observe morphological and mitochondrial ultrastructural changes in the cardiac tissues, and myocardial injury area and collagen volume fraction were calculated. Flow cytometry was applied to detect the relative content and M1/M2 polarization of cardiac macrophages. The mRNA expression levels of macrophage polarization markers [CD86, CD206, arginase 1(Arg-1), inducible nitric oxide synthase(iNOS)], CF markers [type Ⅰ collagen(Coll Ⅰ), Coll Ⅲ, α-smooth muscle actin(α-SMA)], and cytokines(IL-1β, IL-4, IL-6, IL-10, IL-18, TNF-α) in cardiac tissues were determined by quantitative real-time PCR. Western blot was used to detect the protein expression levels of Coll Ⅰ, Coll Ⅲ, α-SMA, Drp1, p-Drp1, voltage-dependent anion channel(VDAC), hexokinase 1(HK1), NOD-like receptor protein 3(NLRP3), apoptosis-associated speck-like protein(ASC), caspase-1, cleaved-caspase-1, gasdermin D(GSDMD), cleaved N-terminal gasdermin D(GSDMD-N), IL-1β, IL-18, B-cell lymphoma-2(Bcl-2), B-cell lymphoma-xl(Bcl-xl), Bcl-2-associated death promoter(Bad), Bcl-2-associated X protein(Bax), apoptotic protease activating factor-1(Apaf-1), pro-caspase-3, cleaved-caspase-3, pro-caspase-9, cleaved-caspase-9, poly(ADP-ribose) polymerase-1(PARP-1), and cleaved-PARP-1 in cardiac tissues. The results showed that VA significantly improved cardiac function in mice with CF, reduced myocardial injury area and cardiac index, and decreased serum levels of AST, CK-MB, cTnI, LDH, ROS, IL-1β, IL-6, IL-18, and TNF-α. VA also lowered MDA and MPO levels, mRNA expressions of IL-1β, IL-6, IL-18, and TNF-α, and mRNA and protein expressions of Coll Ⅰ, Coll Ⅲ, and α-SMA in cardiac tissues, and increased serum levels of IL-4 and IL-10, cardiac tissue levels of CAT, GSH, SOD, and T-AOC, and mRNA expressions of IL-4 and IL-10. Additionally, VA ameliorated cardiac pathological damage, inhibited myocardial cell apoptosis, inflammatory infiltration, and collagen fiber deposition, reduced collagen volume fraction, and alleviated mitochondrial damage. VA decreased the ratio of F4/80~+CD86~+ M1 cells and the mRNA expressions of CD86 and iNOS in cardiac tissue, and increased the ratio of F4/80~+CD206~+ M2 cells and the mRNA expressions of CD206 and Arg-1. VA also reduced protein expressions of p-Drp1, VDAC, NLRP3, ASC, caspase-1, cleaved-caspase-1, GSDMD, GSDMD-N, IL-1β, IL-18, Bad, Bax, Apaf-1, cleaved-caspase-3, cleaved-caspase-9, cleaved-PARP-1, and cytoplasmic cytochrome C, and increased the expressions of HK1, Bcl-2, Bcl-xl, pro-caspase-3, pro-caspase-9 proteins, as well as the Bcl-2/Bax and Bcl-xl/Bad ratios and mitochondrial cytochrome C content. These results indicate that VA has a significant ameliorative effect on ISO-induced CF in mice, alleviates ISO-induced oxidative damage and inflammatory response, and its mechanism may be closely related to the inhibition of Drp1/HK1/NLRP3 and mitochondrial apoptosis signaling pathways, suppression of myocardial cell inflammatory infiltration and collagen fiber deposition, reduction of collagen volume fraction and CollⅠ, Coll Ⅲ, and α-SMA expressions, thus mitigating CF.

Objective To explore the impact of SARS-CoV-2-positive donors on the prognosis of heart transplant recipients. Methods The Medline, EMbase, CENTRAL, CNKI, Wanfang Data, VIP and China Biology Medicine from inception to May 2023 were searched by computer for studies about impact of SARS-CoV-2-positive donors on the prognosis of heart transplant recipients. The data were extracted from all the relevant literatures, and the quality of the data was assessed using the Newcastle-Ottawa Scale (NOS). All statistical analyses were conducted by the Stata 11.0 software. Results A total of 10 studies (NOS score ranging from 5 to 9 points) involving 643 patients were enrolled. The pooled results demonstrated that the pooled mortality of heart transplant recipients from SARS-CoV-2-positive donors was 4% (95%CI 2% to 5%). And the incidence of composite outcome, regarding graft failure, rejection and death as poor prognosis, was 7% (95%CI 5% to 9%). Besides, compared with recipients from SARS-CoV-2-negative donors, the pooled odds ratio (OR) value of death of SARS-CoV-2-positive donors was 0.68 (95%CI 0.38 to 1.22, Z=1.28, P=0.200). The pooled OR value of rejection rate was 0.41 (95%CI 0.27 to 0.64, Z=3.97, P<0.005). For the composite outcome, the pooled OR value was 0.50 (95%CI 0.37 to 0.69, Z=4.30, P<0.005). In addition, there was no statistical difference in the length of hospital stay between heart transplant recipients from SARS-CoV-2-positive donors and negative donors (SMD=–0.03, 95%CI –0.22 to 0.15, Z=0.36, P=0.720). Conclusion The application of heart from SARS-CoV-2-positive donor for transplantation is safe and feasible. However, further prospective studies with longer follow-up are still needed to verify its impact on long-term outcomes.

Background/Aims:
Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China.
Methods:
A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators.
Results:
Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders.
Conclusions
In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

Although olaparib has demonstrated substantial clinical benefits as maintenance therapy in BRCA mutation-carrying women with newly diagnosed advanced ovarian cancer, its effectiveness in patients without BRCA mutations remains poorly investigated. This study aims to provide the first evidence on the efficacy of mono-olaparib maintenance therapy in such context. Using real-world data from 11 high-volume tertiary care centers in China, a retrospective cohort study was conducted to assess the efficacy and safety of olaparib as first-line maintenance therapy in patients with BRCA wild-type ovarian cancer. The primary objective was 1-year progression-free survival rate. Safety was also evaluated. Fifty patients with a median age of 54 years were included, and all of them tested negative for BRCA mutations but positive for homologous recombination deficiency (HRD). The 1-year PFS rate was 75.2% (95% CI, 63.4 to 89.2), and the median PFS was 21.0 months (95% CI, 13.8 to 28.2). All the patients received olaparib at a starting dose of 300 mg twice daily, and none experienced serious adverse events (AEs). Eight (16%) patients had dose adjustment, but none discontinued olaparib treatment due to AEs. We provide the first evidence that mono-olaparib could be a safe and effective maintenance treatment option for patients newly diagnosed with HRD-positive/BRCA wild-type ovarian cancer.

Background:
and Purpose We investigated the causal relationships between the gut microbiota (GM), stroke, and potential metabolite mediators using Mendelian randomization (MR).
Methods:
We leveraged the summary statistics of GM (n=18,340 in the MiBioGen consortium), blood metabolites (n=115,078 in the UK Biobank), and stroke (cases n=60,176 and controls n=1,310,725 in the Global Biobank Meta-Analysis Initiative) from the largest genome-wide association studies to date. We performed bidirectional MR analyses to explore the causal relationships between the GM and stroke, and two mediation analyses, two-step MR and multivariable MR, to discover potential mediating metabolites.
Results:
Ten taxa were causally associated with stroke, and stroke led to changes in 27 taxa. In the two-step MR, Bifidobacteriales order, Bifidobacteriaceae family, Desulfovibrio genus, apolipoprotein A1 (ApoA1), phospholipids in high-density lipoprotein (HDL_PL), and the ratio of apolipoprotein B to ApoA1 (ApoB/ApoA1) were causally associated with stroke (all P<0.044). The causal associations between Bifidobacteriales order, Bifidobacteriaceae family and stroke were validated using the weighted median method in an independent cohort. The three GM taxa were all positively associated with ApoA1 and HDL_PL, whereas Desulfovibrio genus was negatively associated with ApoB/ApoA1 (all P<0.010). Additionally, the causal associations between the three GM taxa and ApoA1 remained significant after correcting for the false discovery rate (all q-values <0.027). Multivariable MR showed that the associations between Bifidobacteriales order, Bifidobacteriaceae family and stroke were mediated by ApoA1 and HDL_PL, each accounting for 6.5% (P=0.028) and 4.6% (P=0.033); the association between Desulfovibrio genus and stroke was mediated by ApoA1, HDL_PL, and ApoB/ApoA1, with mediated proportions of 7.6% (P=0.019), 4.2% (P=0.035), and 9.1% (P=0.013), respectively.
Conclusion
The current MR study provides evidence supporting the causal relationships between several specific GM taxa and stroke and potential mediating metabolites.

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.
