Multimorbidity is significantly associated with life quality decline, disability, and increased mortality risk. Additionally, it leads to greater consumption of healthcare resources, presenting substantial challenges to healthcare systems globally. To better assess the burden of multimorbidity, its impact on patient health outcomes and healthcare services, and to explore the underlying mechanisms in its development, this paper summarizes the existing methods used for measuring and analyzing multimorbidity in research and practice, including disease count, disease-weighted indices, multimorbidity pattern recognition (such as disease association analysis, clustering analysis, and network analysis) and longitudinal methods to provide references for the accurate assessment of the prevalence of multimorbidity and its changes and improve the validity and universality of research findings.

OBJECTIVES: The number of gestational women has been increased in recent years, resulting in more adverse pregnancy outcomes. It is crucial to assess the coagulation function of pregnant women and to intervene in a timely manner. This study aims to analyze the influencing factors on thrombelastography (TEG) and explore the evaluation of TEG for gestational women. METHODS: A retrospective study was conducted on 449 pregnant women who were hospitalized in the obstetrics department in Xiangya Hospital of Central South University from 2018 to 2020. We compared the changes on the TEG parameters among normal pregnant women between different age groups, different ingravidation groups, and different stages of pregnancy groups. The influence on TEG of hypertensive disorders in pregnancy (HDP) and gestational diabetes mellitus (GDM) as well as two diseases synchronization was explored. RESULTS: Compared with the normal second trimester women, the R values and K values of TEG were increased, and α angle, CI values and LY30 values were decreased in third trimester women (all P<0.05). Compared with normal group, the R values and CI values of TEG of the HDP group have significant difference (both P<0.05). There were no significant difference of TEG between the GDM group, the HDP combined with GDM group and the normal group (all P>0.05). Multiple linear regression analysis showed that the influencing factors for R value in TEG were weeks of gestation (P<0.001) and mode of conception (P<0.05), for α angle was weeks of gestation (P<0.05), for MA value was mode of conception (P<0.05), and for CI value was weeks of gestation (P<0.05). The analysis of correlation between TEG with platelet (PLT) and coagulation routines represented that there was a correlation between TEG R values and activated partial thromboplastin time (APTT) (P<0.01), and negative correlation between TEG CI values and APTT (P<0.05). There was a negative correlation between TEG K values and FIB (P<0.05). The correlation of α angle (P<0.05), MA values (P<0.01) and CI values (P<0.05) with FIB were positive respectively. CONCLUSIONS The TEG parameters of 3 stages of pregnancy were different. The different ingravidation approach has effect on TEG. The TEG parameters were consistent with conventional coagulation indicators. The TEG can be used to screen the coagulation status of gestational women, recognize the abnormalities of coagulation and prevent the severe complication timely.

Objective: To investigate the expression level of antisense transcript of pseudogene, general transcription factor Ⅱi psedugen23 (GTF2IP23), in breast cancer and its effect on the host gene general transcription factor Ⅱi (GTF2I). Methods: The expressions of GTF2IP23 and GTF2I were detected in 40 cases of invasive breast cancer tumors and their counterparts by using quantitative real-time polymerase chain reaction (qRT-PCR). The effects of GTF2IP23 on the expression of GTF2I gene and cell proliferation and migration were analyzed by overexpression of GTF2IP23 in breast cancer cells. Results: The expression of GTF2IP23 mRNA in breast cancer tissues was significantly higher than that in adjacent tissues (P<0.001), while the expression of GTF2I mRNA was significantly lower than that in adjacent tissues (P=0.007). The expression of GTF2IP23 was negatively correlated with GTF2I (r=-0.335, P=0.025). The expression of GTF2IP23 in breast cancer cells was significantly higher than in normal breast cells (P<0.01), while GTF2I expression in breast cancer cells was significantly lower than that in normal breast cells (P<0.01). Overexpression of GTF2IP23 in ZR-75-30 cells significantly reduced the expression of GTF2I (P=0.034) and enhanced cell proliferation (P=0.017) and migration (P=0.026) capacity. Conclusions GTF2IP23 is distinctly upregulated in breast cancer, it inhibits the expression of real gene GTF2I and promotes the proliferation of breast cancer cells.

Objective To assess the association between three single nucleotide polymorphisms( SNPs) ( rs10878724、 rs7980829 and rs11177020 ) of lnc IFNG-AS1 and Hashimoto's thyroiditis ( HT) susceptibility. Methods TaqMan probe technology was used to genotype the selected SNPs in a total of 179 subjects, including 70 HT cases, and 109 controls. The expression levels of lnc IFNG-AS1 and IFNG were detected by SYBR-Green qRT-PCR. Results Compared with control, not only the A allele and AA genotype frequencies of rs10878724 were significantly different in group HT ( P=0. 01, P=0. 003), but also the T allele and TT genotype frequencies of rs7980829 were significantly high in group HT. Haplotype analysis showed that the G-G-A decreased the risk of HT (P=0.04), while the haplotype of A-T-T incresed the risk of HT( P=0.01). The relative expression of both IFNG mRNA and lnc IFNG-AS1 were higher in group HT than in control( P=0. 001,P=0. 013). In HT patients, IFNG mRNA relative expression in both rs7980829-TT and rs1087872-TT were significantly higher than those of other genotypes(P=0.017,P=0.009). Conclusion The SNPs of Inc IFNG-AS1 were correlated with the expression levels of IFNG and lncRNA IFNG-AS1. Noncoding genes should be further screened as potential biomarkers in prediction of HT susceptibility.

OBJECTIVETo explore clinical features and mutation types in patients from Fujian area with glutaric academia type I(GA I).

METHODSSerum acylcarnitine and urine organic acid of 3 patients were determined with tandem mass spectrometry and gas chromatographic mass spectrometry. The patients also underwent magnetic resonance imaging analysis for the cranial region. Genomic DNA was extracted from peripheral blood samples, and the 12 exons and flanking regions of the GCDH gene were amplified with PCR and subjected to direct DNA sequencing. One hundred healthy newborns were used as controls.

RESULTSMutations of the GCDH gene were identified in all of the 3 patients. Two patients have carried compound heterozygous mutations including c.1244-2A>C and c.1147C>T(p.R383C), c.406G>T(p.G136C) and c.1169G>A(p.G390E), respectively. One has carried homozygous c.1244-2A>C mutation. The same mutations were not detected among the 100 healthy newborns. Only one patient received early intervention and did not develop the disease. The other two had irreversible damagesto their intelligence.

CONCLUSIONc.1169G>A(p.G390E) is likely pathogenic mutations for GA I patients from Fujianarea. Early screening of neonatal metabolic diseases is crucial for such patients.

A new method of dissolution test was established to better simulate the in vivo dissolution behavior of drugs from preparations and to distinguish the quality difference between drug preparations. With flow-through cell being chosen to be the dissolution apparatus and nimodipine tablet to be the model drugs,this study developed,on the basis of IVIVC theory,a new dissolution method which was subsequently used to evaluate the dissolution con-sistency of domestically produced nimodipine tablet as test preparation and its reference preparation. Meanwhile, conventional four-dissolution-curves method based on paddle apparatus was selected for comparison to evaluate the efficiency of the new dissolution method. The results indicated that the new dissolution method not only had a good correlation with the in vivo process of drugs,but also could reveal the internal quality differences between pharmaceutical preparations effectively. This research will provide further theoretical support for the application of flow-through cell apparatus in IVIVC study.

Objective To analyze the value of abnormal air bronchogram for predicting the invasiveness of lung adenocarcinoma with pure ground-glass nodule (pGGN).Methods From April 2014 to February 2016,157 patients with 165 pGGN lung adenocarcinomas confirmed by surgical pathology were selected.There were 30 pre-invasive lesions (AAH+AIS),39 minimally invasive adenocarcinoma (MIA),and 96 invasive adenocarcinoma (IAC).CT characteristics including lesion size,density,abnormal air bronchogram were recorded.All lesions were divided into two groups:normal group (no air bronchogram or normal air bronchogram) and abnormal air bronchogram group.Chi-square test was used to analyze the difference of pathological subtypes between the two groups.Mann-Whitney rank test was used to analyze the size difference of pGGN between the two groups.Two-independent samples t-test was used to analyze the lesion density difference of pGGN between the two groups.Results Of the 165 lesions,85 were found to have air bronchogram,there were 12 lesions in 30 pre-invasive lesions (AAH+AIS),17 in 39 MIAs,56 in 96 IACs.Abnormal air bronchogram were demonstrated in 61 lesions which was 1 in 30 pre-invasive lesions (IACs+AIS),13 in 39 MIAs and 47 in 96 IACs,significant differences were found between two groups (x2=25.943,P＜0.01).The mean size of the IACs were (10.8±4.2) mm for normal group,(17.0±6.7) mm for abnormal air bronchogram group,the mean density were (-519± 118) HU and (-518± 124) HU,respectively.There was a significant difference in lesion diameter between two groups (Z=-6.197,P＜0.01),but not in density (t=-0.042,P=-0.966).Conclusions Abnormal air bronchogram can be used to predict the invasiveness of pGGN lung adenocarcinoma,and is correlated with lesion size,but not with density.
