OBJECTIVE To investigate the mechanism of Bushen huoxue formula in improving pregnancy outcomes in mice with antiphospholipid antibody-related recurrent spontaneous abortion （aPL-RSA）. METHODS SPF female BALB/c mice were randomly divided into normal control group， adjuvant control group， model group， and Bushen huoxue formula group. The aPL-RSA mouse model was established by immunization with β 2 glycoproteinⅠcombined with Freund’s adjuvant. From gestational day 0， the Bushen huoxue formula group was administered 1.653 6 g/（kg·d） of the prescription by gavage， while the other three groups received an equal volume of normal saline， twice daily for 15 consecutive days. The uterine appearance of pregnant mice was observed； individual embryo weight was recorded， and the embryo resorption rate was calculated. The proportion of activated CD41 + CD62p + platelets in platelet-rich plasma （PRP） was detected. Serum levels of thromboxane B2 （TXB2） and platelet factor 4 （PF4） were measured. Morphological changes of placental tissue were observed. The cell apoptosis rate of placental tissue was detected. The levels of malondialdehyde （MDA） content， tot al superoxide dismutase （T-SOD） activity， the interleukin-1β （IL-1β） and IL-18， the protein expressions of matrix metalloproteinase-3 （MMP-3）， MMP-9， nuclear proliferation antigen-67 （Ki67）， superoxide dismutase 2 （SOD2）， Nod-like receptor protein 3 （NLRP3）， apoptosis-associated speck-like protein containing a CARD （ASC）， and caspase-1， as well as the mRNA expressions of superoxide dismutase 2（SOD2）， NLRP3， ASC and caspase-1 of placental tissue were detected. RESULTS Compared with the normal control group and adjuvant control group， the model group showed significant decreases in individual embryo weight， T-SOD activity of placental tissue， and relative expression levels of SOD2 mRNA and protein （ P ＜0.05）； while significant increases were observed in embryo resorption rate， proportion of activated CD41 + CD62p + platelets in PRP， serum levels of TXB2 and PF4， placental cell apoptosis rate， MDA content in placental tissue， relative protein expressions of MMP-3， MMP-9 and Ki67， relative protein and mRNA expression levels of NLRP3， ASC and caspase-1 as well as IL-1β and IL-18 levels （ P ＜0.05）. The model group also exhibited irregular uterine morphology with localized atrophy in some uterine horns； placental tissue showed fragmentation of decidual cells， extensive vacuolization and necrosis of trophoblast cells in the labyrinthine zone， accompanied by vascular reduction. After intervention with Bushen huoxue formula， the above indicators were significantly reversed （ P ＜0.05）， and uterine morphology and pathological damage were markedly improved. CONCLUSIONS Bushen huoxue formula can effectively improve pregnancy outcomes in aPL-RSA model mice， and its mechanism may be closely related to inhibiting platelet activation， reducing oxidative stress injury， enhancing trophoblast cell function， and suppressing the inflammatory response mediated by the NLRP3 inflammasome pathway.

Objective To Investigate the efficacy of modified electroconvulsive therapy(MECT)in patients with schizophrenia across different genders.Methods From May 2018 to August 2022,481 patients with schizophrenia were recruited from three psychiatric hospitals in Luzhou,Zigong,and Yibin.According to gender grouping,both groups received adjunctive MECT treatment for two consecutive weeks for a total of six treatments.The differences in positive and negative syndrome scale(PANSS)scores before and after treatment,UKU adverse reaction rating scale(UKU),and gastrointestinal symptom rating scale(GSRS)scores were compared between the two groups.Results After quality control,463 cases were followed up for analysis including 246 males and 217 females.Compared with pre-treatment,the total PANSS score and scores on each subscale were significantly reduced in both genders after treatment(P<0.001).When comparing the reduction rates between the groups,the male patients showed a higher reduction rate in negative symptoms than the female patients(31.24%±30.24%vs.25.80%±33.96%,P<0.05).However,there were no significant differences between the two groups in the reduction rates of the total score,positive symptoms,and general psychopathology(P>0.05).The comparison of adverse reactions showed that the frequency of other types of adverse reactions was higher in female patients than in male patients(47.47%vs.37.80%,P<0.05).However,no significant differences were observed in the adverse reactions related to the mental,neurological,autonomic nervous system,and gastrointestinal systems(P>0.05).Correlation analysis revealed that the reduction rate of the PANSS total score was positively correlated with smoking history(r=0.135,P=0.034)and alcohol history(r=0.160,P=0.012)in male patients,while the reduction rate of the PANSS total score was negatively correlated with the disease duration(r=-0.210,P=0.002)and positively correlated with the age of onset(r=0.145,P=0.032)in female patients.Conclusion MECT is significantly effective for both male and female patients with schizophrenia.Compared to female patients,MECT shows a more pronounced effect on negative symptoms in male patients.Additionally,the factors related to the efficacy of MECT differ between genders,indicating that it is necessary to consider the clinical characteristics of patients comprehensively when selecting an MECT treatment plan.

Objective To explore the associations of dietary patterns with bone mineral density(BMD)and osteoporosis(OP)in patients with knee osteoarthritis(KOA)in south China,identify the dietary patterns that could reduce the risk of OP,and provide a reference for prevention of OP.Methods Data from 600 KOA patients who were enrolled in the Pearl River Osteoarthritis Cohort(PROC)between April 2020 and April 2024 were extracted,including general characteristics,dietary questionnaire and BMD test.Factor analysis was employed to identify dietary patterns.Scores of dietary pattern were treated as continuous or categorical variables(quartile-based groups).Multivariable linear regression was used to assess associations between scores of dietary pattern and BMD,while the relationships with OP were analysed by binary logistic regression.Results The prevalence of OP in KOA patients was 19.8%.Factor analysis extracted eight dietary patterns:seafood-nuts,livestock-poultry meats,coarse grains-fruits,wheat-eggs,fish-dairy-vegetables,legumes-fruits,rice-wheat flour,and soy-dairy.After adjusting for confounders,it was found that the pattern of coarse grains-fruits was positively correlated with the BMD of left femoral neck and lumbar spine(P<0.01)and the fish-dairy-vegetables pattern was positively correlated with the BMD of lumbar spine(P<0.01).When pattern scores were discretized into quartiles,the legumes-fruits pattern(Q3 vs.Q1)was found in association with a 68.2%reduction in the risk of OP(P<0.05).Conclusion This study has identified that the pattern of legumes-fruits may lower a risk of OP,while the patterns of coarse grains-fruits and fish-dairy-vegetables correlate with higher BMD.The diet patterns are potentially beneficial to prevention of OP.For bone health,a balanced diet rich in legumes,fruits,vegetables,coarse grains,fish,nuts and dairy is recommended.

Objective To screen the anti-Streptococcus pneumoniae(Spn)active ingredients in vitro from different po-lar parts of Pilea peltata,and to examine the combined antibacterial effect of the active ingredient and amoxicillin(AMX).Methods A 96-well plate microdilution method was used to determine the minimum inhibitory concentration(MIC)of different polar parts;the most active polar part was separated by preparative high-performance liquid chromatography,and the active ingre-dients were identified using spectral technology.The fractional inhibitory concentration(FIC)of active ingredients and AMX was determined by the 96-well plate chessboard microdilution method.The crystal violet method was used to investigate the effect of ac-tive ingredients on Spn biofilm.The effect of active ingredients on the appearance and morphology of Spn was investigated under the electron microscope.Results The MICs of the petroleum ether part,chloroform part,ethyl acetate part,n-butanol part,and water part were 1.000,1.000,0.500,1.000,and 2.000 mg·mL-1 respectively,among which the ethyl acetate part had the stron-gest antibacterial activity.Three compounds were isolated from ethyl acetate,namely 5,7,3',4'-tetramethoxyflavone 1,8-O-(p-coumaroyl)-1(10)E,4(5)E-humuladien-8-ol 2 and 1-O-p-coumaroyl copaborneol 3.These compounds were all isolated for the first time from Pilea peltate,their MICs against Spn were 200.000,50.000,and 25.000 μg·mL-1 respectively,and the compound 3 had the strongest antibacterial activity;the FIC value of AMX and compound 3 was 0.50,which had a synergistic antibacterial effect on Spn.Both AMX and compound 3 had inhibitory effects on Spn biofilm,but the biofilm inhibition rate of compound 3(59.10±1.04％)was significantly lower than AMX(87.38±0.84)％(P＜0.01);Moreover,there was no significant difference in biofilm inhibition rate between the combination of the two and AMX(P＞0.05).The scanning electron microscope results showed that the bacterial cells in the compound 3 group had a smooth surface but varying degrees of depression.The surface of the bacteri-al cells in the AMX group and the AMX combined compound 3 group showed severe swelling and rupture.Conclusions Fla-vonoids and sesquiterpenoids are both the anti-Spn active components of Pilea peltate.Among them,sesquiterpenoids have more potent antibacterial activity,and their antibacterial action mechanism is related to inhibiting bacterial biofilms.Compound 3 and AMX have a synergistic antibacterial effect on Spn,but its mechanism of action is not by enhancing biofilm inhibition;although compound 3 cannot destroy the cell wall of Spn,it still has a negative impact on the appearance of the bacteria.

Objective To investigate the predictive value of pan-immune inflammatory values(PIV)in the prognosis of patients with ischemic stroke(AIS)treated with intravascular intervention combined with tirofiban.Methods 102 AIS cases admitted to the Department of Neurology of the First People's Hospital of Zhaotong from January 2019 to December 2023 and treated with intravascular intervention combined with Tirofiban were selected as the study objects.The patients were divided into the mild group(n=9),moderate group(n=45)and severe group(n=48)according to the score of NIHSS after the admission.According to the mRS 90 days after the treatment,the cases were divided into the good prognosis group(n=63)and poor prognosis group(n=38).Data were collected and analyzed.The predictive value of PIV level in patients with ischemic stroke treated with intravascular intervention combined with tirofiban was evaluated by ROC.The risk factors of adverse outcomes in patients with ischemic stroke treated with intravascular intervention combined with tirofiban were investigated by multivariate Logistic regression.Results A total of 102 patients with ischemic stroke were included.The PIV level in the good prognosis group 331.1(221.9,662.7)was lower than that in the poor prognosis group 1 025.7(451.5,1 841.3)(P<0.05).PIV level in the severe group was higher than that in the mild and moderate groups,and PIV level in the moderate group was higher than that in the mild group(P<0.05).The AUC(95％CI)of PIV for predicting adverse outcomes of intravascular intervention combined with tirofiban in patients with ischemic stroke was 0.750(95％CI 0.654～0.831),the cut-off point was 834.92,the specificity was 85.71％and the sensitivity was 65.79％.NIHSS score>18(OR=5.944 95％CI 2.011～19.137),PIV>834.92(OR=4.863,95％CI 1.410～18.685)were the risk factors for the poor outcome of intravascular intervention combined with tirofiban in patients with ischemic stroke(P<0.05).Conclusion Elevated PIV is closely related to the poor outcomes in patients with ischemic stroke treated with intravascular intervention combined with Tirofiban.High PIV and NIHSS scores are both risk factors for the poor prognosis in patients with ischemic stroke,and can be used as the sensitive indicators for the early identification.

ObjectiveTo investigate the effects of different concentrations of Shaoyaotang-containing serum on lipopolysaccharide （LPS）-induced inflammation of human colorectal adenocarcinoma （Caco-2） cells by inhibiting apoptosis via activating the tumor necrosis factor （TNF） receptor superfamily member 6 （Fas）/Fas ligand （FasL） pathway. MethodsCaco-2 cells were allocated into blank， model （LPS， 10 mg·L^-1）， Shaoyaotang-containing serum （5%， 10%， 15%， 20%）， and Fas inhibitor （KR-33493， 20 mmol·L^-1） groups. Except the blank group， the other groups were stimulated with 10 mg·L^-1 LPS for 24 h for the modeling of inflammation. After successful modeling， the blank， Fas inhibitor， and model groups were treated with blank serum， and the Shaoyaotang-containing serum groups were treated with the serum samples at corresponding concentrations for 24 h. The Fas inhibitor group was subjected to KR-33493 pretreatment for 1 h. Cell proliferation and viability were examined by the cell-counting kit-8 （CCK-8） method. The levels of interleukin （IL）-6， IL-1β， and TNF-α were measured by enzyme-linked immunosorbent assay. Apoptosis was detected by flow cytometry. The protein and mRNA levels of Fas， FasL， cysteinyl aspartate-specific proteinase （Caspase）-3， Caspase-9， B-cell lymphoma 2 （Bcl-2）， and Bcl-2-associated X protein （Bax） were determined by Western blot and Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， respectively. ResultsCompared with the blank group， the model group presented a decrease in cell survival rate （P<0.01）. Compared with that in the model group， the cell survival rate showed no significant change in the 5% Shaoyaotang-containing serum group but increased in the 10%， 15%， and 20% Shaoyaotang-containing serum groups （P<0.01）. Since there was no statistical difference between the 5% Shaoyaotang-containing serum group and the model group， 10%， 15%， and 20% Shaoyaotang-containing sera were selected for the follow-up study. Compared with the blank group， the model group showed risen levels of IL-6， IL-1β， and TNF-α （P<0.01）， an increased apoptosis rate （P<0.01）， up-regulated protein and mRNA levels of Fas， FasL， Caspase-3， Caspase-9， and Bax （P<0.01）， and down-regulated protein and mRNA levels of Bcl-2 （P<0.01）. Compared with the model group， the Fas inhibitor group and the 10%， 15%， and 20% Shaoyaotang-containing serum groups showed declined levels of IL-6， IL-1β， and TNF-α （P<0.01）， decreased apoptosis rates （P<0.01）， down-regulated protein and mRNA levels of Fas， FasL， Caspase-3， Caspase-9， and Bax （P<0.05， P<0.01）， and up-regulated protein and mRNA levels of Bcl-2 （P<0.05， P<0.01）. In addition， the 15% and 20% Shaoyaotang-containing serum groups had lower levels of IL-6， IL-1β， and TNF-α （P<0.05， P<0.01）， lower apoptosis rates （P<0.05， P<0.01）， lower protein and mRNA levels of Fas， FasL， Caspase-3， Caspase-9， and Bax （P<0.05， P<0.01）， and higher protein and mRNA levels of Bcl-2 （P<0.05， P<0.01） than the 10% Shaoyaotang-containing serum group. ConclusionThe Shaoyaotang-containing serum can reduce the content of inflammatory factors in Caco-2 cells， down-regulate the protein and mRNA levels of Fas， FasL， Caspase-3， Caspase-9， and Bax， and up-regulate the protein and mRNA levels of Bcl-2 under the intervention of LPS by regulating the Fas/FasL pathway and inhibiting the apoptosis of intestinal epithelial cells in ulcerative colitis.

ObjectiveTo investigate the protective effect and mechanism of Shaoyaotang （SYD） on the lipopolysaccharide （LPS）-induced damage of tight junction proteins in the human colorectal adenocarcinoma （Caco-2） cell model of inflammation via the Ras homolog gene family member A （RhoA）/Rho-associated coiled-coil forming protein kinase （ROCK） pathway. MethodsCaco-2 cells were grouped as follows： Blank， model （LPS， 10 mg·L^-1）， SYD-containing serum （10%， 15%， and 20%）， and inhibitor （Fasudil， 25 μmol·L^-1）. After 24 hours of intervention， the cell viability in each group was examined by the cell-counting kit 8 （CCK-8） method. Enzyme-linked immunosorbent assay was employed to determine the levels of endothelin-1 （ET-1）， tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and interleukin-6 （IL-6）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were employed to determine the mRNA and protein levels， respectively， of RhoA， ROCK2， claudin-5， and zonula occludens-1 （ZO-1） in cells of each group. ResultsCompared with the blank group， the model group showcased a marked reduction in the cell viability （P<0.01）， elevations in the levels of ET-1， TNF-α， IL-1β， and IL-6 （P<0.01）， declines in both mRNA and protein levels of ZO-1 and claudin-5 （P<0.01）， and rises in mRNA and protein levels of RhoA and ROCK2 （P<0.01）. Compared with the model group， the Shaoyaotang-containing serum （10%， 15%， and 20%） groups had enhanced cell viability （P<0.01）， lowered levels of ET-1， TNF-α， IL-1β， and IL-6 （P<0.01）， up-regulated mRNA and protein levels of ZO-1 and claudin-5 （P<0.05， P<0.01）， and down-regulated mRNA and protein levels of RhoA and ROCK2 （P<0.01）. Moreover， the inhibitor group and the 15% and 20% Shaoyaotang-containing serum groups had lower levels of ET-1， TNF-α， IL-1β， and IL-6 （P<0.05， P<0.01）， higher mRNA and protein levels of ZO-1 and claudin-5 （P<0.05， P<0.01）， and lower mRNA and protein levels of RhoA and ROCK2 （P<0.05， P<0.01） than the 10% Shaoyaotang-containing serum group. ConclusionThe Shaoyaotang-containing serum can lower the levels of LPS-induced increases in levels of inflammatory cytokines and endothelin to ameliorate the damage of tight junction proteins of the Caco-2 cell model of inflammation by regulating the expression of proteins in the RhoA/ROCK pathway.
