Objective: To compare the difference of maternal periodontal status and TNF-? levels in gingival cervical fluid in pregnancy with pre-term and full-term and find the relationship between periodontal infections and pre-term. Methods:The case group consisted of 28 women with pre-term and the control group consisted of 22 women giving birth in time. The clinical examination was performed before delivery. The periodontal conditions were evaluated on the basis of the following parameters: gingival index(GI), probing depths(PD), clinical attachment level(CAL) and sulcus bleeding index(SBI). Gingival crevicular fliud(GCF) samples were collected from all individuals and TNF-? levels were measured by enzyme-linked immunoabsorbent assay. Results:Clinical periodontal measures(GI, PD, CAL, SBI) in pre- term group were significantly greater than that in the control group. And pre- term group also showed higher prevalence of periodontitis. TNF-? in GCF was detected in 67.85% of pre-term group and in 27.27% of the control group. GCF volumes of case group significantly increased than that of control group. Significant negative correlations were observed between the gestational age at delivery and PD as well as GCF- volumes. Conclusion: There is a possible link between periodontal infections and pregnancy with pre-term condition.

Objective To evaluate the value of Compas technique( computed optimun method for profile angle of singht,Compas) in displaying intracranial aneurysms. Methods DSA images of 31 cases of subarachnoid hemorrhage diagnosed by CT were studied. The DSA images in routine A-P and Lateral projections were compared with the images obtained by Compas technique in the same equipment. Results 23 of 31 were diagnosed as intracranial aneurysms by Compas and confirmed by operation, while only 5 were diagnosed definitely with routine A-P & Lateral projections. The other 18 studies were discovered as blurred margin of the artery but indefinite for the diagnosis of aneurysms. There is a statistical difference between the two methods. ?~2=14.93,P

Objective: To evaluate periodontal status of 380 pregnant women and its related factors. Methods: 380 healthy pregnant women aged 20 to 43 at 10-35 weeks of gestation were enrolled and received a questionnaire and a periodontal examination, in order to compare and analyse the effects of different ages, gestational weeks and educational levels on periodontal condition. Results: The prevalence of periodontal disease of the subjects was 87. 1％. In first (10-15 weeks), second (16-27 weeks) and third (28-35 weeks) trimester PD (mm) was 2. 48 ± 0. 54, 2. 60 ± 0. 54 and 2. 71 ± 0. 48 respectively (P ＜ 0. 05) ; the percentage of PD≥4 mm in 2 or more sites were 76. 5％, 84. 1％ and 93. 5％ respectively (P ＜ 0. 05) ; GI and BI did not show significant differences among of the 3 groups trimester stages (P＞ 0. 05) ; PD in maternal age (year) 20-27, 28-35 and 36-43 years was2. 39 ± 0. 51, 2. 61 ± 0. 53 and 2. 61 ± 0. 56 respectively (P ＜ 0. 05) . A significantly positive linear trend was observed between age and GI (P ＜ 0. 05) or PD (P ＜ 0. 05), but without significant correlation between age and BI. Significant correlation was found between pregnant weeks and PD (P ＜ 0. 05), but without correlation between pregnant weeks and GI (P＞ 0. 05) or BI (P＞ 0. 05) .Conclusion: The prevalence of periodontal disease during pregnancy is high. Meanwhile, the periodontal inflammation is increasing worse with the increase of gestational weeks and maternal age.

Objective: To study the mechanism of action of Danggui Shaoyao San (DSS) in the treatment of Alzheimer'sdisease (AD) from a systematic network level using network pharmacology. Methods: The active ingredients of DSS intreating AD was screened from the Traditional Chinese Medicine System Pharmacology Database (TCSMP), and thedrugs-targets-disease network was built. Target organ localization network, GO analysis and Pathway enrichmentanalysis were used for bioinformatics analysis. Results: 51 kinds of DSS active ingredients were screened by networkpharmacology, showing 377 predicted targets of active compounds. Among them, 197 targets were associated with AD, and the pharmacodynamic targets of DSS active compounds were highly enriched with AD-related signals. The pathwaywas closely related to the reduction of Aβ aggregation and inhibition of tau hyperphosphorylation and biological processessuch as anti-inflammatory and anti-apoptosis, and the mRNA expression of the targeted gene was mainly enriched in theliver, heart, and brain. Conclusion: DSS active compounds interact with multiple targets in multiple ways in a synergisticmanner, mainly to produce important therapeutic effects on AD with anti-inflammatory, anti-apoptotic, enhancingmetabolism and immune system.

Objective:To compare the effect and safety of continuous veno-venous hemofiltration (CVVH)+double plasma molecular absorption (DPMA)+hemoperfusion (HP), CVVH+HP, and CVVH+plasma exchange (PE) in treatment of patient with severe wasp stings injury.Methods:Multicenter, historical cohort study and superiority test were used. From July 2020 to October 2022, patients with wasp sting injury and multiple organ damage admitted to the intensive care units (ICU) of five hospitals were consecutively screened and recruited into the CVVH+DPMA+HP group (intervention group). Propensity score matching was used to establish historical cohorts. Patients with severe wasp sting injury who hospitalized from January 2016 to June 2020 in each ICU were collected and matched 1∶1 with the intervention group, and divided into CVVH+HP group and CVVH+PE group according to their actual hemopurification protocols (historical control groups). The primary outcome was the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score on days 3 and 7 after initiation of treatment. Secondary outcomes included complications, length of ICU and hospital stays, and all-cause mortality. Multivariate Cox proportional risk regression was used to analyze the prognosis of patients.Results:After propensity score matching, 56 patients in intervention group and each of the two historical control groups were matched successfully. There were no significant differences in age, gender, comorbidities, biochemical test indices and critical illness scores among the groups. After treatment, APACHE Ⅱ score markedly declined in all groups, and the decrease was faster in the intervention group; treatment with DPMA [hazard ratio ( HR) = 1.04, 95% confidence interval (95% CI) was 1.02-1.08, P = 0.00], the decreased levels of body temperature ( HR = 1.02, 95% CI was 1.00-1.03, P = 0.02), serum creatine kinase (CK; HR = 0.98, 95% CI was 0.96-1.00, P = 0.05) and myoglobin (MYO; HR = 2.88, 95% CI was 1.24-6.69, P = 0.01) were independent risk factors for APACHE Ⅱ score decline to the target value (15 scores). There were no significant differences in the incidence of bleeding complications, filter or perfusion thrombosis, blood pressure reduction, catheter-related infection and anaphylaxis among the groups. Conclusion:CVVH+DPMA+HP regimen can significantly reduce the APACHE Ⅱ score of patients with severe wasp sting injury, and the efficacy is superior to CVVH+HP and CVVH+PE regimens, with safety.

Objective:To evaluate the value of 18F-FDG PET metabolic parameters in predicting histopathological grade of soft tissue sarcoma (STS). Methods:From December 2012 to December 2021, 51 patients (26 males, 25 females, age range: 32-84 years) who underwent 18F-FDG PET/CT imaging before treatment and confirmed STS pathologically in the First Affiliated Hospital of Dalian Medical University were retrospectively collected. 18F-FDG PET metabolic parameters SUV max, metabolic tumor volume (MTV), total lesion glycolysis (TLG) and intertumoral FDG uptake heterogeneity (IFH) were measured. Kruskal-Wallis rank sum test was used to analyze the differences in metabolic parameters among different groups and Spearman rank correlation analysis was used to analyze the correlation of each metabolic parameter and histological grade. Logistic regression was used to screen and construct the prediction model for high-grade STS. ROC curve was plotted and Delong test was used to analyze the differences among AUCs. Results:The metabolic parameters SUV max, MTV, TLG and IFH were significantly different among French Federation of Cancer Centers Sarcoma Group (FNCLCC)Ⅰ( n=8), Ⅱ( n=10) and Ⅲ ( n=33) grade groups ( H values: 16.24, 10.52, 19.29 and 16.99, all P<0.05), and each metabolic parameter was positively correlated with histological grade ( rs values: 0.58, 0.45, 0.52, and 0.62, all P<0.05). Multivariate logistic regression analysis showed that SUV max(odds ratio ( OR)=1.27, 95% CI: 1.06-1.51, P=0.009) and IFH ( OR=6.83, 95% CI: 1.44-32.27, P=0.015) were independent risk indicators for high-grade STS. The prediction model constructed by combining SUV max and IFH had better diagnostic efficacy for differentiating high-grade STS with the AUC of 0.93, and the sensitivity of 93.9%(31/33) and the specificity of 16/18, respectively. The AUC of prediction model was significant different from SUV max, MTV, TLG and IFH (AUCs: 0.81, 0.78, 0.86 and 0.85; z values: 2.69, 2.53, 1.94 and 1.97, all P<0.05). Conclusions:The metabolic parameters SUV max, MTV, TLG and IFH are valuable predictors for histological grade of STS. The combination of SUV max and IFH may be a more meaningful method than using each of the above metabolic parameters alone.
