Objective To conduct Rh blood group serological testing and third-generation sequencing(TGS)on 22 RhD variant voluntary blood donors in Chongqing and explore the phenotypic distribution and genotyping of RhD variants in Chongqing.Methods From January to August 2023,individuals who participated in blood donation in our blood center were selected as the study objects.RhD variant phenotype identification was performed using routine serological methods.Once the RhD variants were identified,tests on different antigenic epitopes of RhD were conducted using a D-screen assay kit.Furthermore,after the genomic DNA from 22 RhD variant blood samples was extracted,imbraided primers design and multi-segment amplification and splicing were used to sequence the full-length RHD gene for TGS.The RHD gene sequence was analyzed using SnapGene software.Results Among the 22 RhD variants,8 were DVI type 3(36.36%),with the main mutation of RHD-CE(3-6)-D hybrid allele.Six cases(27.27%)showed partial weak D15 type,with the main mutation of c.845G>A.There were 6 cases of Asia type Del(27.27%),with the main mutation of c.1227G>A.One case was weak D17 type with a mutation of c.340C>T and 1 case speculated to be partial D(c.491A>T,p.Asp164Val,missense mutation).Conclusion The most common RhD variant phenotype among blood donors in Chongqing is DVI type 3,and the full-length haplotype sequence of RHD variant alleles can be obtained by Pacific Bioscience single-molecule real-time sequencing(SMRT).

The study was a retrospective study. The clinical data of 866 patients with IgA nephropathy (IgAN) in Beijing Anzhen Hospital, Capital Medical University from March 2010 to March 2021 were analyzed, to investigate the clinical pathology and renal prognosis of IgAN patients with intrarenal arteriolosclerosis, and to preliminarily explore whether abnormal activation of complement system is involved in the injury of arteriolosclerosis. The patients were divided into renal arteriolar lesions group and non-renal arteriolar lesions group according to the renal histopathology, and the differences of clinical pathological manifestations, prognosis between the two groups were compared. The results showed that, compared with the non-renal arteriolar lesions group ( n=236), IgAN patients in the renal arteriolar lesions group ( n=630) had higher proportions of hypertension and malignant hypertension, higher levels of urinary albumin-creatinine ratio, 24-hour urine protein quantification and serum uric acid, lower estimated glomerular filtration rate, and more severe MEST-C lesions of the Oxford classification (all P < 0.05). Cox regression analysis results showed that intrarenal arteriolosclerosis was the independent risk factor affecting the progression of IgAN to ESRD ( HR=6.437, 95% CI 2.013-20.585, P=0.002). Renal histopathology showed that the deposition of complement C3c on the wall of intrarenal arterioles in the renal arteriolar lesions group ( n=98) was stronger than that in non-renal arteriolar lesions group ( n=18, P < 0.05). IgAN patients with renal arteriolosclerosis present with serious clinical and pathological manifestations, and renal prognosis. Abnormal activation of complement system may be involved in the pathogenesis of intrarenal arteriolosclerosis.

Objective:To analyze the prevalence of different genotypes of wild measles virus in Fujian province from 2014 to 2019.Methods:The information of suspected measles cases and the throat swab specimens of the cases in Fujian province from 2014 to 2019 were collected. Reverse transcription-polymerase chain reaction was applied to amplify the 450 nucleotides of the 3-terminal of the nucleoprotein gene. Phylogenetic tree was constructed to identify and analyze the target sequence.Results:A total of 1 102 suspected measles cases were reported in Fujian province from 2014 to 2019, with an annual incidence rate of 0.47/100 000. Totally 884 throat swabs were tested in the laboratory, and 179 nucleotide sequences were obtained except vaccine strain. Sequence analysis showed that 110 measles genotypes were H1, 43 were B3 and 26 were D8. Nucleotide homology analysis showed that the H1a genotype measles virus in Fujian province distributed in two branches, divided into nine different sequence variants. Some of the variants were highly homologous (99.8%-100.0%) with the measles strains in other regions and countries. There were six different sequence variants of B3 genotype measles virus in Fujian province. The nucleotide homology between the B3 genotype measles virus in Fujian province and the domestic and foreign prevalent B3 strains was 98.4%-100.0%. The D8 genotype measles strain in Fujian province had five different sequence variants, some of which were highly homologous with the strains from Vietnam, Japan and Thailand.Conclusions:Three different genotypes of measles viruses (H1, B3 and D8) prevailed in Fujian province from 2014 to 2019, among which H1 genotype was still the local endemic genotype, while B3 and D8 genotypes were imported genotypes in Fujian province. The result indicated that although the local cases of measles were less in Fujian province in recent years, the risk of imported cases from abroad was increasing, and the surveillance of imported cases from abroad should be strengthened.

Objective:To investigate the level of mumps virus (MuV) IgG antibody of healthy population and the genotyping of MuV in Fujian province in 2018.Methods:MuV IgG antibody of healthy population was detected by enzyme-linked immunosorbent assay (ELISA). Small hydrophobin (SH) gene of MuV was genotyped in pharyngeal swab and cell cultures of mumps patients using reverse transcription polymerase chain reaction (RT-PCR). The phylogenetic tree by SH sequences was constructed to identify MuV genotype.Results:A total of 4 925 people completed antibody testing, the positive rate of MuV IgG antibody was 78.58%(3780/4925), and the geometric mean concentration (GMC) was 245.83 IU/ml. There was no statistically significant difference in the positive rate of antibodies between people of different genders, while GMC had statistically significant differences ( χ2=4.295, P=0.117; Z=-2.220, P=0.026). There were significant differences in the positive rate of antibodies and GMC between people in different regions and age groups. Especially in infants and 12-15 years old group of people, the MuV IgG antibody positive rate and GMC were at low levels. The antibody positive rate and GMC of people with a history of mumps-containing vaccine (MuCV) immunization were higher than those without a history of MuCV immunization and those with unknown MuCV immunization history ( χ2=259.315, P<0.001; Z=-16.319, P<0.001). Eight strains of MuV were isolated from the mumps outbreak, which were all F genotypes. Conclusion:The immune level of mumps in infants and young children in Fujian province was low, and the 12-15 age group is the focus of attention. The epidemic strains of MuV in Fujian province in 2018 were mainly F genotype strains.

Objective:To analyze the complete genome sequence characteristics of genotype G mumps virus isolated from Putian city, Fujian province in 2015.Methods:Two mumps virus strains isolated in Putian city, Fujian province in 2015 were selected for the study and named as MuV15-01 and MuV15-23.The whole genome of the isolated strains was amplified by reverse transcription-polymerase chain reaction (Rt-PCR). The genetic differences and antigen site variation of the isolated strain were analyzed by comparing the sequences of vaccine strain and other genotypes strains.Results:The total length of genome of MuV isolates was 15, 384 nucleotides. The nucleotide differences between isolates and other genotypes of mumps virus based on the whole genome ranged between 3.7% and 6.0%. The maximum and minimum difference was found between isolates and genotype A (the vaccine strains), and genotype B to N strains, respectively. Among the nucleotide sequences encoding different viral proteins, SH gene had the largest variation, while M and L genes were the most conserved. There were 7 and 11 amino acid mutations in the known antigen related sites of N gene and HN gene, respectively. Compared with the vaccine strain, the isolated strain added an additional N-glycosylation site to the 464 site of the HN gene.Conclusions:Genetic variations were detected in the epidemic mumps virus strains in Putian, Fujian, compared with other mumps genotypes and vaccine strains based on the whole genome. These resluts indicate that the monitoring for genetic differences between epidemic mumps strains and vaccine strains should be further strengthened.

Objective:We isolated and identified the genotypes and molecular characteristics of the imported B3 measles virus (MeV) in Fujian province in 2018.Methods:Throat swab specimens were collected from clinically diagnosed measles patients and tested for viral RNA, using the real-time reverse transcription-polymerase chain reaction after the RNA extraction. Reverse transcription-polymerase chain reaction method was undertaken to amplify the 634 nucleotide acids of 3-terminal of the nucleoprotein gene. A phylogenetic tree was constructed and similarities in homology assessed.Results:We successfully isolated and obtained two measles virus strains and eighteen viral nucleic acid sequences. The Fujian strains were clustered within the same genotype group of WHO genotype B3 reference strains. Compared to the major circulating measles strain genotype B3 in the world, two Fujian strains MV18-41 and MV18-42 showed 100.0 % nucleic acid homology to HongKong.CHN/35.18 strain which was isolated from Hong Kong in 2018. The remaining 16 Fujian strains showed the highest homology (99.9 %) with the Mvs/Osaka.JPN/38.18/B3 strain isolated from Japan in 2018. Compared with other 23 WHO genotype reference strains, homology on both nucleotide and amino acid of the Fujian strain and the B1 genotype reference strain were the smallest, as 95.1 %-95.4 % and 95.3 %, respectively. The differences of homology between the Fujian strain and H1 genotype reference strain were the largest, as 88.7 %-89.0 % and 87.3 %, respectively. In addition, there were 13 mutation sites between the Fujian strain and the vaccine strain (Shanghai-191) at the 150 amino acid position of carboxy terminus on N protein, However, these sites did not cause functional changes in the protein region. Conclusions:In Fujian province, two strains of B3 genotype measles virus were obtained successfully, which were considered to be new genotype measles virus found in 2018. These findings showed it is necessary to strengthening the monitoring program on imported cases for better control and eliminate the measles virus.

Objective To evaluate the safety of heparin used in plasma exchange (PE) and molecular absorbent recirculating system (MARS) for hepatic failure. Methods 8 databases were electronically searched including CNKI,CBM,WANFANG,VIP,PubMed,Web of Science,Cochrane and EMBASE.Two researchers individually performed the literature screening,data extraction and evaluation of risk of bias.Random or fixed effect model based on the result of the test of heterogeneity were chosento synthesize the datausing RevMan 5.3 software. Results 6 eligible studies with 863 patientswere included. Compared to omitting of heparin, the heparin PE could increase the probability of circuit clotting, hemorrhage in puncture point, puncture hematoma (RR = 6.05, 95% CI:2.00-18.30, P=0.001;RR=10.80,95% CI:4.78-24.37,P<0.05;RR=6.34,95% CI:1.13-35.53,P=0.04),but the probability of circuit blocking and other adverse reactions are not influenced(RR=5.61,95% CI:0.99-31.89,P=0.05;RR = 1.17,95% CI: 0.73-1.86, P=0.51). As for the treatment with MARS, heparin could increase the chance bleeding death (RR =12.04, 95% CI:1.69-85.66, P=0.01), but had no obvious effect on circuit clotting. Conclusion When curing the hepatic failure,heparin PE can increase the probability of circuit clotting, hemorrhage in puncture point and puncture hematoma, and heparin MARSE can increase the probability of bleeding death. On the contrary, no-heparin PE and MARSE will be safer in treatment of hepatic failure.
