Cost-effectiveness analysis of nucleic acid screening for hepatitis B and C in hospitalized patients in China / 中华检验医学杂志

Objective:To compare the cost-effectiveness of hospitalized Chinese patients undergoing nucleic acid screening strategies for hepatitis B and hepatitis C, immunological screening strategy, and no screening strategy under different willingness to pay (WTP). The results might aid to decision-making for the optimal strategy.Methods:In this study, nucleic acid screening, immunological screening and no screening were used as screening strategies, and China′s GDP in 2021 (80 976 yuan) was used as the threshold of WTP to construct a Markov model. After introducing parameters related to the diagnosis and treatment of hepatitis B and C in inpatients, a cohort population of 100 000 inpatients was simulated by TreeAge Pro 2021 software, the total cost, total health effects, incremental cost-effectiveness ratio and average cost-effectiveness ratio of different screening strategies were calculated, and cost-effectiveness analysis was conducted. Univariate and probabilistic sensitivity analysis were used to assess the impact of parameter uncertainty on the final results.Results:Compared with the non-screening strategy, the incremental total cost of the hepatitis B immunological screening strategy for cohort patients was 11 049 536 yuan, and the incremental cost-effectiveness ratio was 24 762 yuan/quality-adjusted life years (QALY), while the total incremental cost of nucleic acid screening was 19 208 059 yuan, and the incremental cost-effectiveness ratio was 29 873 yuan/QALY; the incremental cost-effectiveness ratio of nucleic acid screening and immunological screening was 45 834 yuan/QALY. Compared with the non-screening strategy, the incremental cost-effectiveness ratio of hepatitis C immunological screening strategy was 5 731 yuan/QALY, the incremental cost-effectiveness ratio of nucleic acid screening strategy was 8 722 yuan/QALY, the incremental cost-effectiveness ratio of nucleic acid screening and immunological screening was 45 591 yuan/QALY. The results of probabilistic sensitivity analysis showed that when the cost of nucleic acid testing exceeded 214.53 yuan, it was not cost-effective to perform hepatitis B nucleic acid screening under the WTP as 1 fold GDP. When the cost of nucleic acid testing exceeded 132.18 yuan, it was not cost-effective to conduct hepatitis C screening under the WTP as 1 fold GDP.Conclusions:Nucleic acid screening strategy can achieve more cost-effectiveness and is worthy of vigorous promotion. Compared with no screening, both the nucleic acid and immunological screening strategies are cost-effective, and hepatitis nucleic acid screening is the optimal strategy for hospitalized patients.

A multicenter study assessing the efficacy of various preoperative/pre-transfusion screening methods for blood transmitted disease / 中华检验医学杂志

Objective:This multi-centre study was conducted to assess the efficacy of various preoperative/pre-transfusion screening methods for blood transmitted disease.Methods:From July 2021 to December 2021, plasma samples of patients admitted to 10 hospitals were collected for screening preoperative/pre-transfusion blood transmitted disease. Nucleic acid detection technology was used to detect hepatitis B virus (HBV) DNA, hepatitis C virus (HCV) RNA and human immunodeficiency virus (HIV)(1+2) RNA, and the results were compared with the immuno-serological methods. χ 2 test and Kappa test were used to analyze the efficacy of these two methods. Results:A total of 8 655 valid specimens were collected from 10 hospitals. There was a statistically significant difference in the positive detection rate of HCV between the two methods ( P<0.001). There was no significant difference in the positive detection rate of HBV and HIV assessed by the two methods ( P>0.05), but the number of positive cases detected by HBV DNA and HIV RNA (218 and 4 cases) was significantly higher than the corresponding serological results (216 and 2 cases). At the same time, there were HBV, HCV and HIV immuno-serological omissions by the immuno-serological methods, among which 28 cases were HBsAg negative and HBV DNA positive, 2 cases were HCV antibody negative and HCV RNA positive, and 2 cases were HIV antigen/antibody negative and HIV RNA positive. In addition, in the 66 samples with inconsistent results from the two detection methods, 83.3% (55/66), 68.2% (45/66), 63.6% (42/66) and 62.1% (41/66) of patients aged was>45 years, tumor, surgery and male, respectively. Conclusions:Compared with immuno-serological tests, nucleic acid tests have the advantage in terms of sensitivity on detecting HBV, HCV and HIV infection and could reduce missed detection. The risk of transmission can be reduced by adding HBV, HCV, and HIV nucleic acid tests to preoperative/pre-transfusion immuno-serological tests screening for patients over 45 years of age and tumor patients.

Clinical value of nucleic acid detection for hepatitis B virus screening in hospitalized patients / 中华检验医学杂志

Objective:To explore clinical value of nucleic acid detection for hepatitis B virus (HBV) screening in hospitalized patients.Methods:This cross-sectional study collected and analyzed plasma samples from patients admitted to 10 domestic medical institutions from July 2021 to December 2021. Serological immunoassay and nucleic acid screening were used to simultaneously detect hepatitis B markers such as hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B e Antigen (HBeAg), hepatitis B e antibody (HBeAb), hepatitis B core antibody (HBcAb),and HBV DNA. Statistical analysis was performed on the serology, nucleic acid test results and clinical information of the patients.Results:Of the 8 655 collected samples, HBsAg was positive in 216 (2.50%) samples,HBV DNA was positive in 238 (2.75%) samples ( P>0.05); 210 (2.43%) samples were positive for both HBsAg and HBV DNA, 28 (0.32%) were HBsAg negative and HBV DNA positive, 6 cases (0.07%) were HBsAg positive and HBV DNA negative. Conclusion:These results indicate that the HBV DNA testing is equally effective as hepatitis B virus serological detection for hepatitis B virus screening in hospitalized patients.

Age-related change in mitochondrial DNA copy number and its correlation with intrinsic capacity and body composition / 中华老年医学杂志

Objective:To investigate the correlation of peripheral blood relative mitochondrial DNA copy number(mtDNAcn)with intrinsic capacity and body composition, and to identify potential biomarkers for healthy aging.Methods:Clinical data of 416 patients admitted to our hospital from September 2019 to June 2021 were consecutively collected.MtDNA was extracted from peripheral blood of these subjects, and mtDNAcn was determined by a real-time fluoresence quantitative reverse transcription-polymerase chain reaction(qRT-PCR). Intrinsic capacity assessment included 5 aspects that were exercise[Morse Fall Scale(MFS), Physiological Frailty Phenotype(PFP), Sarcopenia Questionnaire(SARC-CALF), Short Physical Performance Battery(SPPB), Time Up and Go Test(TUG)]; vitality[Mini Nutritional Assessment(MNA), Multidimensional Prognostic Index(MPI)]; cognition[Mini-Mental State Examination(MMSE)scale]; psychology[Geriatric Depression Scale(GDS), Self-rating Anxiety Scale(SAS)]; sensory capacities[Cumulative Illness Rating Scale-the Comorbidity Index(CIRS-CI)]. To assess body composition, dual-energy X-ray absorptiometry was used to measure body fat, including trunk fat, total body fat, fat in the abdominal region, fat in the buttock region, and then to calculate fat index(FMI)and limb skeletal muscle mass index(ASMI).Results:Spearman correlation analysis showed that mtDNAcn had a negatively correlation with age( r=-0.176, P<0.05). After adjustment for gender and body mass index, partial correlation analysis showed mtDNAcn were still negatively correlated with age( r=-0.144, P<0.05). Furthermore, mtDNAcn was significantly correlated with 4 m gait speed, the scores of SARC-CalF, MFS, MNA, MMSE, MPI and its sub-scale's Activities of Daily Living(ADL)and Short Portable Mental Status Questionnaire(SPMSQ)( r=0.171, -0.207, -0.163, 0.221, 0.184, -0.210, 0.241, -0.269, all P<0.05). After adjustment for age, gender and body mass index, partial correlation analysis showed mtDNAcn still had a significant correlation with gait speed, the scores of MFS, MNA, MPI and SPMSQ( r=0.170, -0.170, 0.148, -0.242, -0.188, all P<0.05). In addition, the Spearman correlation analysis showed that mtDNAcn was positively correlated with FMI, trunk fat, total body fat, abdominal fat and fat in the buttock region( r=0.168, 0.143, 0.175, 0.116, 0.199, all P<0.05). However, after adjustment for age and gender, mtDNAcn was only correlated with FMI, total body fat, fat in the buttock region( r=0.126, 0.131, 0.127, all P<0.05). On the other hand, multiple linear regression analysis showed that mtDNAcn was significantly correlated with age, gait speed, FMI, total body fat, fat in the buttock region, the scores of MFS, PFP, MNA and MPI( β=-0.191, 0.156, 0.126, 0.131, 0.125, -0.119, -0.145, 0.151, -0.171, all P<0.05). Conclusions:MtDNAcn is correlated with physical function, frailty, nutrition, falling, cognition and body composition, and may be considered as a biomarker for the evaluation of the locomotion and vitality of human intrinsic capacity.

Application of SifaInDel 45plex System in the Han and Mongolian Populations / 法医学杂志

OBJECTIVES@#To investigate the genetic polymorphism of InDel loci in SifalnDel 45plex system in the Han population in Jiangsu Province and the Mongolian population in Inner Mongolia, and to evaluate the effectiveness of the system in forensic medicine.@*METHODS@#SifaInDel 45plex system was used for genotyping in blood samples of 398 unrelated individuals from the above two populations, and allele frequencies and population genetic parameters of the two populations were calculated respectively. Eight intercontinental populations in the gnomAD database were used as reference populations. The genetic distances between the two studied populations and eight reference populations were calculated based on the allele frequencies of 27 autosomal-InDels (A-InDels). The phylogenetic trees and multidimensional scaling (MDS) analysis diagrams were constructed accordingly.@*RESULTS@#Among two studied populations, the 27 A-InDels and 16 X-InDels showed no linkage disequilibrium between each other and the allele frequency distributions were in Hardy-Weinberg equilibrium. The CDP of the 27 A-InDels in two studied populations were all higher than 0.999 999 999 9, and the CPEtrio were all less than 0.999 9. The CDP of the 16 X-InDels in Han in Jiangsu and Mongolian in Inner Mongolia female and male samples were 0.999 997 962, 0.999 998 389, and 0.999 818 940, 0.999 856 063, respectively. The CMECtrio were all less than 0.999 9. The results of population genetics showed that the Jiangsu Han nationality, Inner Mongolia Mongolian nationality and East Asian population clustered into one branch, showing closer genetic relationship. The other 7 intercontinental populations clustered into another group. And the above 3 populations displayed distant genetic relationships with the other 7 intercontinental populations.@*CONCLUSIONS@#The InDels in the SifaInDel 45plex system have good genetic polymorphism in the two studied populations, which can be used for forensic individual identification or as an effective complement for paternity identification, and to distinguish different intercontinental populations.

OBJECTIVES@#To study the genetic polymorphism and population genetic parameters of 16 X-STR loci in Xinjiang Uygur population.@*METHODS@#The Goldeneye® DNA identification system 17X was used to amplify 16 X-STR loci in 502 unrelated individuals (251 females and 251 males). The amplified products were detected by 3130xl genetic analyzer. Allele frequencies and population genetic parameters were analyzed statistically. The genetic distances between Uygur and other 8 populations were calculated. Multidimensional scaling and phylogenetic tree were constructed based on genetic distance.@*RESULTS@#In the 16 X-STR loci, a total of 67 alleles were detected in 502 Xinjiang Uygur unrelated individuals. The allele frequencies ranged from 0.001 3 to 0.572 4. PIC ranged from 0.568 8 to 0.855 3. The cumulative discrimination power in females and males were 0.999 999 999 999 999 and 0.999 999 999 743 071, respectively. The cumulative mean paternity exclusion chance in trios and in duos were 0.999 999 997 791 859 and 0.999 998 989 000 730, respectively. The genetic distance between Uygur population and Kazakh population was closer, and the genetic distance between Uygur and Han population was farther.@*CONCLUSIONS@#The 16 X-STR loci are highly polymorphic and suitable for identification in Uygur population, which can provide a powerful supplement for the study of individual identification, paternity identification and population genetics.

Efficiency Analysis of Uncle-Nephew Relationship Identification by Increasing STR Markers and Adding Reference Samples / 法医学杂志

OBJECTIVES@#To estimate the system efficiency of uncle-nephew relationship identification by increasing STR markers and adding reference samples based on the test results of simulated data and real samples, so as to provide references for selecting the appropriate number of STRs and reference samples for uncle-nephew relationship identification.@*METHODS@#Five common models of uncle-nephew relationship identification were constructed by adding different reference samples. In each model, the likelihood ratio (LR) for 10 000 pairs of uncle-nephew relationships and 10 000 pairs of unrelated individuals were simulated by detecting 19, 39 or 55 STRs, and the system efficiency at different thresholds was simulated. The samples of the Han population in Zhejiang were collected, and 55 autosomal STRs were obtained by using SiFaSTRTM 23plex kit, Goldeneye® DNA ID 22NC kit and AGCU 21+1 PCR amplification kit. When 19, 39 and 55 STRs were detected, the LR of each model and system efficiency under different thresholds were calculated and compared with the simulation results.@*RESULTS@#Under the same detection system, the calculated results of simulated data and corresponding true samples were basically consistent. In the same model, there was a positive correlation between the system efficiency of uncle-nephew relationship identification and the number of STRs detected. Moreover, the system efficiency of introducing relatives was higher than identifying only two individuals. The order of preference for the introduction of relatives was the full sibling (or mother) of the uncle and the full sibling (or mother) of the nephew.@*CONCLUSIONS@#The system efficiency of uncle-nephew relationship identification could be improved by increasing the number of STRs and introducing known relatives, which would provide the basis for selecting the most appropriate detection system and reference individuals in actual cases.

Effects of long non-coding RNA FAM224A on the proliferation and migration of ovarian cancer cells by regulating the expression of miRNA-590-3p / 肿瘤研究与临床

Objective:To explore the effects of long non-coding RNA (lncRNA) FAM224A on the proliferation and migration of ovarian cancer cells by regulating the expression of miRNA-590-3p (miR-590-3p).Methods:Human ovarian cancer cell lines OC3, SKOV-3, HO-8910, A2780 and human normal ovarian epithelial cell line IOSE80 were selected, and the relative expression of FAM224A in each cell line was detected by real-time quantitative polymerase chain reaction (qRT-PCR). The cell line with the lowest relative expression level of FAM224A was screened for follow-up experiment. The cells were divided into FAM224A group (transfected with FAM224A mimic gene) and control group (transfected with control mimic gene). CCK-8 method and cell scratch test were used to detect the cell proliferation and migration ability of the two groups. The bioinformatics website LncBase v.2 predicted that the target gene that FAM224A might complementarily bind to was miR-590-3p. qRT-PCR was used to detect the relative expression levels of miR-590-3p and forkhead box protein A2 (FOXA2) mRNA, and the expressions of related proteins were detected by Western blot.Results:The relative expression levels of FAM224A in ovarian cancer cell lines OC3, SKOV-3, HO-8910, A2780 and normal ovarian epithelial cell line IOSE80 were 0.23±0.04, 0.65±0.05, 0.45±0.03, 0.63±0.08 and 1.02±0.11, respectively, and the difference was statistically significant ( F = 14.78, P < 0.01), and the cell line with the lowest relative expression level of FAM224A was OC3. The results of CCK-8 method showed that the proliferation ability of OC3 cells in the FAM224A group was lower than that in the control group on the 2nd, 3rd, 4th and 5th day of culture (all P < 0.05). The scratch healing rates of OC3 cells in the FAM224A group and the control group were (18.6±2.3)% and (71.7±7.2)%, respectively, and the difference was statistically significant ( t = 6.99, P < 0.01). The relative expression levels of FAM224A in OC3 cells in the FAM224A group and the control group was 12.36±1.45 and 1.14±0.24, respectively ( t = 13.08, P < 0.01); the relative expression levels of miR-590-3p were 0.19±0.06 and 1.04±0.20, respectively ( t = 4.01, P < 0.01); the relative expression levels of FOXA2 mRNA were 6.37±1.37 and 1.05±0.08, respectively ( t = 3.86, P < 0.01). Compared with the control group, the expression of FOXA2 protein in OC3 cells in the FAM224A group was increased, the expressions of cell proliferation protein cyclin-dependent kinase 2 (CDK2) and cyclin D3 were decreased, and the expression of cell migration protein Snail was decreased. Conclusions:FAM224A is low expressed in ovarian cancer cell lines. FAM224A reduces the proliferation and migration ability of ovarian cancer OC3 cells by inhibiting the expression of miR-590-3p.

Association between coagulation function and prognosis in patients with acute pancreatitis / 南方医科大学学报

OBJECTIVE@#To explore the correlation of coagulation function with the severity and prognosis of acute pancreatitis (AP) and identify the laboratory markers for early prediction and dynamic monitoring of the prognosis of AP.@*METHODS@#We retrospectively analyzed the clinical data of patients with AP admitted less than 72 h after onset to our hospital from December 1, 2017 to November 30, 2018. The correlation of coagulation function-related markers at admission and their changes during hospitalization with the prognosis of the patients was analyzed.@*RESULTS@#We screened the data of a total of 1260 patients with AP against the inclusion and exclusion criteria, and eventually 175 patients were enrolled in this analysis, among whom 52 patients had severe AP (SAP) and 12 patients died. Logistic regression analysis identified vWF: Ag, PT, PC, AT Ⅲ and D-dimer markers at admission as independent risk factors for predicting SAP and death. Dynamic monitoring of the changes in coagulation function-related markers in the disease course had greater predictive value of the patients' prognosis, and the indicators including vWF: Agmax, PTmax, APTTmax, TTmax, FIBmin, D-dimermax, PLTmin, PCmin, PLGmin, AT Ⅲmin, and their variations were all independent risk factors for predicting SAP and death. ROC analysis suggested that dynamic monitoring of the changes in the indicators, especially those of △vWF: Ag, △PT, △APTT, △FIB, △TT, △D-dimer, △PLT, △PC, △AT Ⅲ, △PLG, could effectively predict SAP and death in these patients (with AUC range of 0.63-0.84).@*CONCLUSION@#Patients with AP have vascular endothelial injuries and coagulation disorders. The markers including vWF: Ag, PT, PC, AT Ⅲ and D-dimer at admission are independent risk factors for predicting SAP and death, and dynamic monitoring of the changes in vWF: Ag、PT、APTT、TT、FIB、D-dimer、PLT、PC、AT Ⅲ and PLG can further increase the predictive value.

OBJECTIVE@#To compare the clinical efficacy and its effect on serum levels of tumor necrosis factor α(TNF-α), interleukin 1β(IL-1β), interleukin 6 (IL-6) and prostaglandin E2 (PGE2) between short needling (close-to-bone needling) and conventional acupuncture for knee osteoarthritis (KOA) with blood stasis obstruction.@*METHODS@#A total of 68 KOA patients with blood stasis obstruction were randomized into a short needling group (34 cases, 3 cases dropped off) and a conventional acupuncture group (34 cases, 3 cases dropped off). The same acupoints (Dubi [ST 35], Neixiyan [EX-LE 4], Binzhong [Extra], Liangqiu [ST 34], etc. on the affected side) were selected in the two groups. In the short needling group, short needling technique was adopted, the needles were slowly inserted and the needle bodies were shaken, thus gradually penetrated to the bone. In the conventional acupuncture group, conventional acupuncture was adopted, the needles were penetrated to the muscle. After qi-arrival, Dubi (ST 35) and Neixiyan (EX-LE 4), Zusanli (ST 36) and Liangqiu (ST 34) were connected with CMNS6-1 electronic acupuncture instrument, with disperse-dense wave, 2 Hz/10 Hz in frequency, the current intensity was based on patients' feeling, the needles were retained for 30 min, at the same time, the knee joint was irradiated for 30 min with a special electromagnetic wave apparatus in the two groups. Once every other day, 3 times a week for 4 weeks. Before and after treatment, the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score, knee joint pain visual analogue scale (VAS) score, inflammatory response related indexes (serum TNF-a, IL-1β, IL-6 and PGE2) and knee joint ultrasound were observed，and the clinical effect was evaluated in the two groups.@*RESULTS@#After treatment，the pain, stiffness, function scores and total scores of WOMAC were decreased as compared with those before treatment in the two groups (P<0.05), except for the pain score, the changes of above scores in the short needling group were greater than the conventional acupuncture group (P<0.05). After treatment, the VAS scores, serum levels of TNF-a, IL-1β, IL-6, PGE2 and knee joint synovium thickness, intra-articular effusion were decreased as compared with those before treatment in the two groups (P<0.05), the levels of TNF-a, IL-1β, IL-6 in the short needling group were lower than the conventional acupuncture group (P<0.05). The total effective rate in the short needling group was 87.1% (27/31), which was superior to 83.9% (26/31) in the conventional acupuncture group (P<0.05).@*CONCLUSION@#Short needling could improve the knee joint function, relieve the pain and inflammatory response, improve the knee joint synovium inflammatory response, reduce the knee joint intra-articular effusion for KOA patients, its effect is better than conventional acupuncture.

Effect of Sodium Salicylate on Calcium Currents and Exocytosis in Cochlear Inner Hair Cells: Implications for Tinnitus Generation / 神经科学通报·英文版

Sodium salicylate is an anti-inflammatory medication with a side-effect of tinnitus. Here, we used mouse cochlear cultures to explore the effects of salicylate treatment on cochlear inner hair cells (IHCs). We found that IHCs showed significant damage after exposure to a high concentration of salicylate. Whole-cell patch clamp recordings showed that 1-5 mmol/L salicylate did not affect the exocytosis of IHCs, indicating that IHCs are not involved in tinnitus generation by enhancing their neuronal input. Instead, salicylate induced a larger peak amplitude, a more negative half-activation voltage, and a steeper slope factor of Ca2+ current. Using noise analysis of Ca2+ tail currents and qRT-PCR, we further found that salicylate increased the number of Ca2+ channels along with CaV1.3 expression. All these changes could act synergistically to enhance the Ca2+ influx into IHCs. Inhibition of intracellular Ca2+ overload significantly attenuated IHC death after 10 mmol/L salicylate treatment. These results implicate a cellular mechanism for tinnitus generation in the peripheral auditory system.

The sociodemographic information of children and their caregivers was collected using self-designed questionnaire.The dietary diversity score(DDS)was calculated according to the criteria in the Guidelines for Measuring Household and Individual Dietary Diversity released by the Food and Agriculture Organization of the United Nations.The body height(length)and body weight of each child were measured by standard equipment for anthropological measurement,and the height for age Z score(HAZ),weight for age Z score(WAZ),and weight for height Z score(WHZ) were calculated.Multivariate linear regression was performed to analyze the relationship between dietary diversity and growth indicators of children. Results A total of 1092 children were enrolled in this study,and the prevalence of stunting(HAZ<-2),underweight(WAZ<-2),and wasting(WHZ<-2)was 21.1%,4.9%,and 2.5%,respectively.The children had the mean DDS of 4.8±1.7,and 45.3% of children had poor dietary diversity(DDS≤4).The children of Han ethnic group(5.8±1.4)had higher DDS than those of Tibetan ethnic group(4.9±1.6)and Yi ethnic group(3.9±1.6)(P<0.001).The results of multivariate linear regression indicated that DDS was positively correlated with HAZ(β=0.206,95%CI=0.158-0.254,P<0.001)after adjustment of sex,age,birth weight,preterm birth,and parental body height.After further adjustment of family fixed assets,ethnic group,caregiver's type,and caregiver's education background,the correlation between DDS and HAZ remained significant(β=0.077,95%CI=0.026-0.128, P=0.003). Conclusions The children in the multi-ethnic rural areas of Sichuan province showed troublesome growth and development status and low dietary diversity,which were conspicuously different between ethnic groups,especially in the rural areas of Yi ethnic group.The dietary diversity was positively associated with HAZ.It is recommended to carry out nutrition and health education according to the local dietary characteristics and thus improve the growth and development of children in multi-ethnic rural areas in Sichuan.

Detection of platelet antibody and evaluation of platelet transfusion efficacy in patients with hematologic disease / 中国输血杂志

【Objective】 To investigate the factors influencing the production of platelet antibody and its effect on clinical platelet transfusion. 【Methods】 This is a single-center prospective observational study. The research subjects were patients with hematological diseases in West China Hospital of Sichuan University from October 1, 2018 to September 30, 2019, and their plasma were collected before platelet transfusion to detect platelet antibodies using solid-phase agglutination method. According to the results of platelet antibody screening, the patients were divided into platelet antibody positive group and negative group. The t test and nonparametric Mann-Whitney U test were used to compare the transfusion efficacy of two groups. Patients’ demographic and clinical information, including age, gender, diagnosis, the units of platelets and RBC transfused, were collected via HIS6.2.0 and whole process management system of blood in clinical (version 3.0) to analyze the influence of age, gender and the disease on the positive rate of platelet antibodies, as well as the profile of platelet antibodies in patients with different diseases, the correlation between the positive rate of platelet antibodies and the history of blood/platelets transfusion. In additional, the platelet transfusion process was observed on site. 【Results】 A total of 316 patients with hematologic diseases were included in this study, mainly with acute myeloid leukemia(188/316, 59.5%). All patients were transfused 1671 U platelet [1~17(5.3±3.1)U each person] and 1896 U RBC products [0~38(7.8±4.6)U each person] during the treatment. Out of the 316 patients, platelet antibodies were found in 85 (26.9%) of them. No significant differences in the positive rates of platelet antibody after transfusion were notice by genders or ages(P>0.05). The incidence of platelet antibody was related to diseases (P<0.05), with MDS as the highest (57.1%), followed by aplastic anemia (36.4%) and myeloid leukemia (27.7%). In additional, the positive rate of platelet antibody increased with the number of previous platelet transfusions(P<0.05). The 316 patients were divided into positive group and negative group according to the results of platelet antibody screening. The corrected count of increment (5.2×109/L vs 11.5×109/L, P<0.01) and absolute platelet increase(8×109/L vs 17×109/L, P<0.01)in positive group were lower than those in negative group. The positive group were transfused more units of platelets(1.7 U vs 1.2 U, P<0.01)and red blood cells(1.5 U vs 1.1 U, P<0.05)per week than negative group. The platelet transfusion interval was shorter in positive group than negative group (3.1 days vs 3.6 days, P<0.05), but there was no significant difference in red blood cell transfusion interval (3.1 days vs 3.8 days, P>0.05) between two groups. The minimum PLT count(5×109/L vs 9×109/L, P<0.01), average PLT count(27×109/L vs 40×109/L, P<0.01)and average Hb(71 g/L vs 77 g/L, P<0.05)in positive group were lower than those in negative group during hospitalization, but there was no significant difference in the minimum Hb(56 g/L vs 59 g/L, P>0.05)between two groups. According to transfusion events on site, the incidence of acute adverse reactions to transfusion was 13% (169/1 291). 【Conclusions】 The positive rates of platelet antibodies in patients with hematologic diseases were relatively high. In addition, the efficacy of platelet transfusion in positive group were worse than that in the negative group. It is recommended that platelet antibody testing should be routinely performed before transfusion in hematologic disease patients to select crossmatch-compatible platelets in order to improve the effectiveness of platelet transfusion.

Effects of delivery and feeding modes on intestinal microflora in infants with atopic dermatitis / 中华皮肤科杂志

Objective:To investigate the effect of different delivery and feeding modes on intestinal microflora in infants with atopic dermatitis (AD) .Methods:A total of 33 infants with AD were enrolled from Department of Dermatology, Wuhan NO.1 Hospital from July 2019 to December 2020, and 30 healthy infants were selected as control group. Then, all infants were grouped according to different delivery and feeding modes: cesarean-delivery AD group (22 cases) , cesarean-delivery control group (19 cases) , spontaneous-delivery AD group (11 cases) , and spontaneous-delivery control group (11 cases) ; mixed-feeding AD group (13 cases) , mixed-feeding control group (11 cases) , formula milk powder-feeding AD group (12 cases) , formula milk powder-feeding control group (11 cases) , breastfeeding AD group (8 cases) , and breastfeeding control group (12 cases) . The total DNA was extracted from the infant feces, PCR was performed to amplify the V1 - V9 regions of bacterial 16S rRNA gene, and PacBio Sequel sequencer was used for high-throughput sequencing. Wilcoxon rank sum test was used to compare the bacterial community composition at genus and species levels, and correlations of relative abundance of differentially abundant bacterial taxa with eosinophil counts and SCORing Atopic Dermatitis (SCORAD) scores were analyzed.Results:In the spontaneous-delivery control group, cesarean-delivery control group, spontaneous-delivery AD group, and cesarean-delivery AD group, the top 5 bacterial genera with high relative abundance were Bifidobacterium, Bacteroides, Veillonella, Streptococcus, and Escherichia. In the formula milk powder-feeding control group, breastfeeding control group, mixed-feeding control group, formula milk powder-feeding AD group, breastfeeding AD group, and mixed-feeding AD group, the top 5 abundant bacterial genera were Bifidobacterium, Bacteroides, Clostridium, Veillonella, and Escherichia. Linear discriminant analysis of effect size (LEfSe) showed no significant difference in the relative abundance of bacterial taxa among different delivery mode groups; among different feeding mode groups, Akkermansia and Akkermansiamuciniphila were the most differentially abundant microbes in the formula milk powder-feeding AD group at genus (LDA = 4.78) and species (LDA = 4.91) levels, respectively. The relative abundance of Akkermansia and Akkermansiamuciniphila (both 9.6% ± 0.72%) was significantly higher in the formula milk powder-feeding AD group than in the formula milk powder-feeding control group (both 2.50% ± 0.83%, Z = 1.66, P = 0.048) , the mixed-feeding AD group (both 0, Z = 2.26, P = 0.012) and the breastfeeding AD group (both 0, Z = 1.85, P = 0.032) . Additionally, the relative abundance of Akkermansia and Akkermansia- muciniphila was positively correlated with SCORAD scores in AD patients ( ρ = 0.384, 0.387, respectively, both P < 0.05) . Conclusion:Different delivery modes did not significantly affect the intestinal flora of AD or healthy infants, and the relative abundance of Akkermansia and Akkermansiamuciniphila increased in the formula milk powder-feeding infants with AD, which may be involved in the occurrence of AD.

Association of glucose metabolism with adverse pregnancy outcomes in pregnant women of Chongming area / 中华内分泌代谢杂志

Objective:To investigate the risk factors of hyperglycemia during pregnancy and its correlation with adverse pregnancy outcomes based on the retrospective analysis of glucose metabolism of pregnant women in Chongming area.Methods:A total of 604 singleton pregnant women who underwent prenatal examination and delivered normally in the Chongming branch of Xinhua Hospital from September 2019 to May 2021 were enrolled in the study. All subjects were divided into normal glucose tolerance gestation (NGTG) group and gestational diabetes mellitus (GDM) group. Pregnant women whose blood glucose exceeded normal but did not meet the diagnostic criteria of GDM were classified into the intermediate state gestational blood glucose (ISGBG) group. Questionnaire, physical examination, and relevant laboratory tests were completed. Data were analyzed using the Statistical Product and Service Solutions 13.0 (SPSS, Chicago, IL).Results:The incidence rate of GDM was 20.86% (126/604), ISGBG was 40.39% (244/604), and NGTG was 38.74% (234/604) in 604 pregnant women. Multivariate logistic regression analysis showed that gestational age ( OR=1.092, P<0.001), serum triglyceride ( OR=1.625, P=0.001) and free T 3 levels ( OR=1.995, P=0.002) were independent risk factors for GDM. The incidence of pregnancy-induced hypertension, cesarean section, macrosomia, the total incidence of adverse pregnancy outcomes and fetal birth weight in ISGBG and GDM were significantly higher than those in NGTG ( P<0.05 or P<0.01). Conclusion:The incidence of GDM in Chongming area is high, especially higher in that of ISGBG. As both GDM and ISGBG lead to increased adverse pregnancy outcomes, early monitoring should be paid more attention to pregnant women in ISGBG in addition to the early intervention of GDM.

Escore de Risco Clínico Simples para Prever a Mortalidade Pós-Alta Hospitalar em Pacientes Chineses Hospitalizados por Insuficiência Cardíaca / A Simple Clinical Risk Score to Predict Post-Discharge Mortality in Chinese Patients Hospitalized with Heart Failure

Resumo Fundamento Doenças cardiovasculares são a principal causa de morte na China. Entretanto, os esforços atuais para se identificar os fatores de risco de morte em pacientes hospitalizados com insuficiência cardíaca (IC) estão direcionados principalmente para a mortalidade durante a internação e a mortalidade após 30 dias nos Estados Unidos. Dessa forma, é necessário um modelo semelhante ao modelo utilizado para prever o risco considerado para procedimentos cirúrgicos cardiovasculares em pacientes para avaliar o risco de pacientes internados com diagnóstico de IC. Objetivo Identificar variáveis que podem prever a mortalidade por IC um ano após a alta hospitalar, e desenvolver um escore de risco para avaliar o risco de morte no período de um ano. Métodos No presente estudo, 1.742 pacientes chineses com IC foram divididos aleatoriamente em dois grupos: um grupo de amostra de derivação e um grupo de amostra de teste. O método de simulação Monte Carlo via Cadeias de Markov foi usado para identificar variáveis que podem prever a mortalidade um ano após a alta hospitalar. Variáveis com uma frequência >1% na análise bivariada, e que foram consideradas clinicamente significativas, foram qualificadas para análises de modelagens posteriores. A probabilidade posterior de que uma variável estava estatística e significativamente associada ao resultado foi calculada como o número total de vezes em que o IC de 95% da variável não coincidiu com 1 (ou seja, o ponto de referência), dividido pelo número total de iterações. Uma variável com uma probabilidade de 0,9 ou mais alta foi considerado um fator de risco robusto para prever o resultado, e foi incluída na lista final de variáveis. O nível de significância estatística adotado foi 5%. Resultados Cinco variáveis que pudessem prever de maneira robusta a mortalidade um ano após a alta hospitalar foram identificadas: idade, sexo feminino, escore da New York Heart Association (Associação de Cardiologia de Nova Iorque) >3, diâmetro do átrio esquerdo, e índice de massa corporal. Os modelos de derivação e de teste tiveram uma área de curva característica de operação do receptor de 0,79. Essas variáveis selecionadas foram utilizadas para avaliar o escore de risco de mortalidade por IC após um ano, e este foi dividido em três grupos (baixo, moderado e alto). O grupo de alto risco corresponde a aproximadamente 86% das mortes, e o grupo de risco moderado corresponde a 12% das mortes. Conclusão Um escore de risco de 5 variáveis simples pode ser utilizado para avaliar a mortalidade um ano após a alta hospitalar de pacientes internados com IC.

Abstract Background Cardiovascular diseases are the leading causes of death in China. However, present efforts to identify the risk factors for death in patients hospitalized with heart failure (HF) are primarily focused on in-hospital mortality and 30-day mortality in the United States. Thus, a model similar to the model used for predicting the risk in patients considered for cardiovascular surgical procedures is needed to evaluate the risk of the patients admitted with a diagnosis of HF. Objective To identify variables that can predict post-discharge one-year HF mortality and develop a risk score to assess the risk of dying within one year. Methods In the present study, 1,742 Chinese patients with HF were randomly divided into two groups: a derivation sample group and a test sample group. A Markov Chain Monte Carlo simulation method was used to identify variables that can predict the one-year post-discharge mortality. Variables with a frequency of >1% in the bivariate analysis and that were considered clinically meaningful were eligible for further modeling analyses. The posterior probability that a variable was statistically and significantly associated with the outcome was calculated as the total number of times that the variable's 95% CI did not overlap with 1 (i.e., the reference point) divided by the total number of iterations. A variable with a probability of 0.9 or higher was considered a robust risk factor for predicting the outcome, and this was included in the final variable list. The level of statistical significance adopted was 5%. Results Five variables that could robustly predict the one-year post-discharge mortality were identified: age, female gender, New York Heart Association functional classification score >3, left atrial diameter, and body mass index. Both derivation and test models had a receiver operating curve area of 0.79. These selected variables were used to assess the one-year HF mortality risk score, and these were divided into three groups (low, moderate, and high). The high-risk group corresponds to nearly 86% of the deaths, while the moderate group corresponds to 12% of the deaths. Conclusion A simple 5-variable risk score can be used to assess the one-year post-discharge mortality of hospitalized Chinese patients with HF.
