OBJECTIVE To compare the efficacy and safety of different daily doses of aspirin in the prevention of preeclampsia （PE）. METHODS The case-control studies and prospective randomized controlled trials on aspirin with daily dose ≥ 100 mg （trial group） vs. ＜100 mg （control group） in the prevention of PE were retrieved from PubMed， Medline， Embase， the Cochrane Library， CNKI， China Biomedical Literatue Database and Wanfang Data from base-building to January 2025. After literature screening， data extraction and quality evaluation， meta-analysis was performed by using RevMan 5.3 software. RESULTS A total of 11 literatures were included， involving 3 052 pregnant women. Meta-analysis showed the incidence of PE [RR＝0.63， 95%CI （0.53，0.76）， P＜0.000 01]， gestational hypertension [RR＝0.69， 95%CI （0.50，0.94），P＝0.02]， preterm birth [RR＝0.56， 95%CI （0.47，0.66）， P＜0.000 01]， and intrauterine growth retardation [RR＝0.73，95%CI （0.61，0.87），P＝0.000 5] in trial groups were significantly lower than control group. The incidence of postpartum hemorrhage between the two groups had no statistically significant difference [RR＝1.17， 95%CI （0.90，1.53），P＝0.25]. Subgroup analysis showed that the incidence of PE in Chinese pregnant women taking 150 mg of aspirin was significantly higher than taking 100 mg of aspirin [RR＝3.40， 95%CI （1.29， 8.93）， P＝0.01]； but there was no significant difference between the two groups in the incidences of postpartum hemorrhage， preterm birth （P＞0.05）. CONCLUSIONS Aspirin with daily dose ≥100 mg is more effective in preventing PE than daily dose ＜100 mg， with lower rates of gestational hypertension， preterm birth， and intrauterine growth retardation. It does not increase the risk of postpartum hemorrhage. For pregnant women in China， daily dose 100 mg of aspirin may be more effective in preventing PE than 150 mg.

Objective To explore the association between mammalian sterile 20-like kinase 1(MST1)gene poly-morphism and haplotype and the risk of colorectal cancer,rectal cancer,and colon cancer in the Han population in Baotou area by case-control association study.Methods A total of 390 patients with colorectal cancer diagnosed by pathology and 413 normal physical examination population were collected,and 2 ml of peripheral blood was taken for subsequent gene genotyping.Single nucleotide polymorphisms(SNPs)of MST1 gene were screened according to the genetic polymorphism data of Chinese Han population provided by the National Center for Biotechnology In-formation-Haplotype Mapping database.Gene genotyping was performed by Taqman method.Logistic regression was used to calculate the association between each SNP and the risk of colorectal cancer,colon cancer,and rectal cancer under codominant,dominant,overdominant,and recessive genetic models.Results Four SNPs of MST1 gene were screened,namely rs8000,rs2234197,rs2267853,and rs6073629.Among them,SNP rs2234197 was associated with the risk of rectal cancer.Compared with the GG+AA genotype,the AG genotype could reduce the risk of rectal cancer,OR[95%confidence interval(CI)]=0.657(0.442-0.976).SNP rs8000 was associated with the risk of colon cancer.Compared with the TT+GT genotype,the GG genotype could reduce the risk of colon cancer[OR(95%CI)=0.425(0.182-0.992)].Conclusion MST1 gene SNP rs2234197 AG genotype and SNP rs8000 GG genotype may be protective factors for rectal cancer and colon cancer,respectively.

Objective To investigate the associations of the single nucleotide polymorphism (SNP) rs2304733 in TEA domain transcription factor 1 (TEAD1) , rs7135838 and rs1990330 in TEA domain transcription factor 4 (TEAD4) genes with the risk of non-cardia gastric carcinogenesis.Methods Enzyme linked immunosorbent assay (ELISA) was used to detect specific antibodies against Helicobacter pylori(Hp) in serum samples of the normal con-trol group.470 normal controls were divided into Hp infection negative group (n=223) and positive group (n=247) based on antibody titers.In the 450 non-cardia gastric cancer cases and 470 controls, polymerase chain reac-tion-restriction fragment length polymorphism (PCR-RFLP) was used to genotype the each SNP locus.The uncon-ditional Logistic regression method was used to evaluate the associations between each SNP locus and the risk of non-cardia gastric carcinogenesis.Results The SNPs of TEAD1 and TEAD4 were not associated with Hp infec-tion.TEAD1 rs2304733 was associated with the risk of non-cardia gastric cancer.Compared with the carriers of TT genotype, the carries of CT and CC genotypes had an increased risk of non-cardia gastric cancer (CT vs TT:OR=2.321 , 95％CI:1.690-3.188;CC vs TT:OR=5.140 , 95％CI:1.080-24.463) .TEAD4 rs1990330 was as-sociated with the risk of non-cardia gastric cancer.Compared with the carriers of GG genotype, those with GT geno-type had an increased risk of non-cardia gastric cancer (OR = 2.405 , 95％ CI: 1.480 - 3.908) .TEAD4 rs7135838 was not associated with the risk of non-cardia gastric cancer.TEAD1 rs2304733, TEAD4 rs7135838 and rs1990330 had interaction effects on the risk of non-cardia gastric cancer (P<0.05).Conclusion In Baotou Han population, TEAD1 rs2304733 and TEAD4 rs1990330 do not play a major role in Hp infection, but may play a role in the risk of non-cardia gastric cancer.TEAD4 rs7135838 may not play a major role in the risk of Hp infec-tion and non-cardia gastric cancer.TEAD1 rs2304733 and TEAD4 rs1990330 have the strongest synergistic effect on the risk of non-cardia gastric cancer, which is the best interaction model.

ObjectiveTo evaluate the validity of four screening questionnaires on chronic obstructive pulmonary disease (COPD) among community residents in Shanghai, and to provide a scientific basis for selecting suitable screening questionnaires and plans for the community use. MethodsA multi-stage random sampling method was used to select community residents aged ≥40 for COPD questionnaire screening and spirometry. The screening questionnaires included the COPD Population Screener Questionnaire (COPD-PS), the COPD Screening Questionnaire (COPD-SQ), the COPD Diagnosis Questionnaire (CDQ), and the Lung Function Questionnaire (LFQ). The diagnostic gold standard for COPD was defined as a ratio of post-bronchodilator forced expiratory volume in one second to forced vital capacity (FEV1/FVC) less than 0.7. The receiver operating characteristic (ROC) curve was used to assess the validity of each questionnaire, and DeLong’s test was used to compare the area under the curve (AUC) of different questionnaires. ResultsAmong the 1 122 residents screened, 99 (8.8%) were diagnosed with COPD based on the gold standard criteria. The AUC values for the four questionnaires ranged from 0.643 to 0.682, with no statistically significant differences in screening accuracy among them (P>0.05). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for each questionnaire at recommended cut-off points were as follows: COPD-PS (sensitivity: 33.3%, specificity: 84.9%, PPV: 17.6%, NPV: 92.9%), COPD-SQ (34.3%, 85.8%, 19.0%, 93.1%), CDQ (73.7%, 42.4%, 11.0%, 94.4%), and LFQ (48.5%, 74.8%, 15.7%, 93.8%). Optimal cut-off values for this population differed from the recommended values. When selecting the optimal cut-off value, the sensitivity of COPD-PS (58.6%), COPD-SQ (55.6%), and LFQ (64.7%) increased, while the specificity of CDQ (75.9%) increased. The AUC of sequential lung function testing for all four screening questionnaires increased to 0.7 or above. The optimal cut-off values for the four questionnaires in this population differed from the recommended values. When applying the optimal cut-off values, the sensitivity of three questionnaires increased: COPD-PS (58.6%), COPD-SQ (55.6%), and LFQ (64.7%), while the specificity of CDQ rose to 75.9%. The AUC of each questionnaire increased to above 0.7 when followed by sequential lung function testing. ConclusionThe COPD-PS, COPD-SQ, CDQ, and LFQ have limited value for COPD screening among Shanghai community residents, indicating that further refinement of these tools is needed.

BACKGROUND:In the past,it was necessary to cut off the pronator quadratus muscle in the treatment of distal radius fractures.Failure to repair the pronator quadratus muscle can lead to a series of complications. OBJECTIVE:To explore the clinical efficacy of different methods of preserving the pronator quadratus muscle combined with a palmar steel plate in the treatment of distal radius fractures. METHODS:Clinical data of 66 patients with distal radius fractures were retrospectively included,divided into the traditional Henry approach group(group A),the split brachioradialis tendon approach group(group B),and the posterior pronator quadratus muscle approach group(group C),with 22 patients in each group.Postoperative internal fixation,fracture healing,and postoperative complications were observed in the three groups.The visual analog scale score of postoperative wrist pain and forearm rotation angle were compared among the three groups.The Dienst Joint Scale was used to evaluate the wrist function of patients. RESULTS AND CONCLUSION:(1)The surgical time,intraoperative blood loss,and fracture healing time of groups B and C were significantly lower than those of group A(P<0.01).There was no significant difference in intraoperative blood loss and fracture healing time between groups B and C,but the surgical time was shorter in group B.(2)The anteroposterior and lateral wrist X-ray examination 3 days and 1 and 3 months after surgery exhibited that there were no significant differences in radial height,palm angle,and ulnar deviation angle among the three groups(P>0.05).No significant difference was detected in various indicators during the same phase among the three groups(P>0.05).(3)At a follow-up of 12 months after surgery,there were no significant differences in visual analog scale scores and forearm rotation angle among the three groups.However,the evaluation results at 1 and 3 months after surgery demonstrated significant differences in visual analog scale scores and forearm rotation angle among the three groups(P<0.05).Among them,group C had a lower visual analog scale score and a larger forearm rotation angle.(4)According to the Dienst joint scoring standard,the excellent and good rate of wrist joint function evaluation was 86%(19/22),91%(20/22),and 95%(21/22)in groups A,B,and C,respectively 12 months after surgery.(5)All patients did not experience any postoperative vascular or neurological damage or surgical site infection.Group A had three cases of tendon irritation,two cases of traumatic arthritis,and two cases of carpal tunnel syndrome.In group B,tendon irritation occurred in 1 case and joint stiffness in 1 case.There was 1 case of traumatic arthritis and 1 case of carpal tunnel syndrome in group C.(6)It is suggested that different surgical methods for treating distal radius fractures have achieved good clinical results.Placing a steel plate under the pronator muscle can alleviate early postoperative pain,promote early activity,and restore normal life.The brachioradialis tendon approach has more advantages in exposing intraoperative fractures and can shorten the surgical time.

Objective To investigate the diagnostic value of serum levels of leukocyte cell derived chemo-taxin 2(LECT2)and tumor necrosis factor ligand-related molecule-1A(TL1A)in children with atopic der-matitis(AD).Methods A total of 83 children with AD who were adimitted to the hospital from August 2021 to August 2023 were selected as the AD group,and 83 healthy children who underwent physical examination in the hospital during the same period were selected as the control group.Enzyme linked immunosorbent assay(ELISA)was applied to measure the expression levels of LECT2 and TL1A in serum.Spearman method was applied to analyze the correlation between serum LECT2,TL1A,and AD integral index(SCORAD).Multiva-riate Logistic regression was applied to analyze the factors that affected the severity of AD in children.Receiv-er operating characteristic(ROC)curve was applied to analyze the diagnostic efficacy of serum LECT2 and TL1A levels on the severity of AD in children.Results Compared with the control group,the expression lev-els of LECT2 and TL1A in the serum of the AD group were significantly increased(P＜0.05).Compared with the low-grade group,the serum LECT2,TL1 A,SCORAD score,EOS and total IgE in the moderate and severe groups were significantly increased in turn(P＜0.05).According to Spearman correlation analysis,the serum levels of LECT2 and TL1A in the AD group were positively correlated with the SCORAD score(r=0.776,0.693,both P＜0.05).According to the results of multivariate Logistic regression analysis,serum LECT2、TL1 A、EOS and total IgE were risk factors affecting the severity of AD in children(P＜0.05).In ad-dition,the combination of serum LECT2 and TL1A had the highest AUC for diagnosing the severity of AD in children,which was better than the individual diagnosis of serum LECT2 and TL1A(Z=2.249,1.989,P=0.025,0.047).Conclusion The elevated levels of serum LECT2 and TL1A in children with AD are closely re-lated to the severity of the disease,and the combination of the two can better evaluate the severity of the dis-ease in children with AD.

The research literature on the mechanism of Achyranthis Bidentatae Radix and its main components in the treatment of osteoporosis was reviewed. It was found that Achyranthis Bidentatae Radix could promote the osteogenic differentiation of bone marrow mesenchymal stem cells, enhance the activity of osteoblasts, inhibit the activity of osteoclasts, regulate estrogen levels, and achieve the effects of preventing and treating osteoporosis. It mainly regulates Wnt/β-catenin, Notch, PI3K/Akt and other signaling pathways. The mechanism of Achyranthis Bidentatae Radix in the treatment of OP shows the characteristics of multi-component, multi-target and multi-pathway.

Objective:To investigate the differences in glucose homeostasis and amino acid metabolism between patients with new-onset T2DM with qi-yin deficiency syndrome and those with spleen deficiency and phlegm-dampness syndrome.Methods:This study was a cross-sectional and cohort study. From January 2021 to December 2022, 136 T2DM inpatients were selected from the Department of Metabolic Diseases of Shanxi Traditional Chinese Medicine Hospital, and 18 patients were screened to meet the inclusion criteria of new-onset T2DM, and were identified as qi-yin deficiency syndrome and sspleen deficiency and phlegm-dampness syndrome, and were included in corresponding qi-yin and deficiency group and spleen deficiency and phlegm-dampness group, with 9 cases in each group. All patients wore a dynamic blood glucose monitoring system to calculate the 24-h mean standard deviation of blood glucose (SDBG), the coefficient of variation of blood glucose (GLU cv), the maximum value of blood glucose (GLU max), the minimum value of blood glucose (GLU min), the maximum amplitude of glucose fluctuation (LAGE), the average amplitude of glucose fluctuation (MAGE), and the proportion of time within the target range of blood glucose (TIR). Blood specimens were retained for amino acid metabolism testing to screen for differential metabolites and metabolic pathways in the 2 groups of syndromes. Results:Patients in the spleen deficiency and phlegm-dampness group had mAlb [27.61 (13.60,40.45) mg/L vs. 5.10 (1.95, 9.70) mg/L, Z=-2.34], GLU-0 h [(14.83±4.79) mmol/L vs. (9.72±2.35) mmol/L, t=2.87], GLU-1 h [(24.40±5.23) mmol/L vs. (17.71±2.68) mmol/L, t=3.42], GLU-2 h [(25.17±4.43) mmol/L vs. (19.69±3.11) mmol/L, t=3.03], HOMA2-IR [1.83 (1.46, 3.19) vs. 1.14 (0.90, 1.35), Z=-2.14] were higher than those in the qi-yin deficiency syndrome ( P<0.05), GLU cv [16.86 (13.58, 26.20)% vs. 28.30 (23.17, 40.87)%, Z=-2.08] was lower than that of the qi-yin deficiency syndrome ( P<0.05) and had severe blood glucose fluctuations. Screening of 2 groups of differential metabolites identified threonine, alanine, and glutamine as potential metabolic markers for T2DM with qi-yin deficiency versus spleen deficiency and phlegm-dampness. Analysis of the 2 groups of differential metabolite pathways for different TCM syndromes revealed that Aminoacyl-tRNA biosynthesis was the most significantly enriched pathway. Conclusion:Patients with T2DM spleen deficiency and phlegm dampness syndrome had worse insulin function and glucose homeostasis than those with qi-yin deficiency syndrome; differences in amino acid metabolism were important influences on the development of the 2 types of the syndromes, namely, spleen deficiency and phlegm dampness syndrome versus qi-yin deficiency syndrome; and Aminoacyl-tRNA biosynthesis participates in the development of early diabetes mellitus, which plays a key role in the pathogenesis of T2DM.
