Objective:To investigate the efficacy of pungent-heat-dampness-drying method combined with methotrexate in the treatment of rheumatoid arthritis with cold-dampness blockage syndrome and its effect on knee joint function.Methods:A randomized controlled study was conducted on 120 patients with rheumatoid arthritis exhibiting cold-dampness blockage syndrome, who were admitted to the Quzhou Municipal Hospital of Traditional Chinese Medicine between July 2020 and October 2022. Using the random number table method, these patients were randomly assigned to either the control group ( n = 60) or the observation group ( n = 60). The control group received methotrexate tablets exclusively, while the observation group received a combined therapy of pungent-heat-dampness-drying method along with methotrexate. All patients were treated for 4 weeks. At the end of the treatment period, improvements in clinical indices and knee joint function were compared between the two groups. Results:After 4 weeks of treatment, the activity pain time [(0.95 ± 0.05) hours], rest pain time [(0.62 ± 0.08) hours], morning stiffness duration [(0.65 ± 0.02) hours], and pain paralysis duration [(0.52 ± 0.083) hours] in the observation group were significantly lower than those in the control group [(2.13 ± 0.15) hours, (1.36 ± 0.14) hours, (1.23 ± 0.63) hours and (1.02 ± 0.52) hours, respectively] ( t = 57.81, 35.55, 7.13, 7.44; all P < 0.001). The Knee Society Score in the observation group was (35.42 ± 8.26) points, which was significantly higher than that in the control group [(20.23 ± 5.75) points, t = -11.69, P < 0.001]. Additionally, levels of alanine aminotransferase, aspartate aminotransferase, erythrocyte sedimentation rate, and C-reactive protein were significantly lower in the observation group compared to the control group ( t = 26.96, 57.72, 19.44, 12.61, 17.37; all P < 0.05). The knee joint function score in the observation group was (75.42 ± 5.26) points, which was significantly higher than that in the control group [(62.23 ± 5.65) points, t = -13.24, P < 0.05]. Conclusion:The combination of the pungent-heat-dampness-drying method with methotrexate for the treatment of rheumatoid arthritis with cold-dampness blockage syndrome not only effectively improves clinical indices but also significantly reduces knee joint pain and improves knee joint function.

OBJECTIVETo establish a polymerase chain reaction sequencing-based typing (PCR SBT) method for HLA-DPB1 exons 2 and 3, and to analyze their polymorphisms.

METHODSBased on the sequences of HLA-DPB1 loci, locus-specific primers were designed and applied to amplify the target sequences encompassing the entire exons 2 and 3 of HLA-DPB1. The amplification products were digested by enzymes and directly sequenced in both directions. The genotype was assigned by Assign 3.5+ SBT software.

RESULTSSpecific target fragment was obtained with the PCR amplification, and good quality electropherogram was derived by direct sequencing. Among 242 individuals from Zhejiang Han population, 18 HLA-DPB1 alleles were detected. Alleles with a frequency of > 0.05 have included DPB1*05:01:01/135:01 (0.4112), DPB1*02:01:02 (0.1901), DPB1*04:01:01 (0.1136) and DPB1*02:02 (0.0620). A novel HLA-DPB1*168:01 allele has also been identified. Nine polymorphism sites were founded in the exon 3 region, which included a new SNP site 517 A>T.

CONCLUSIONThe PCR-SBT method for exons 2 and 3 of HLA-DPB1 is reliable, which allowed detection of polymorphisms in exon 3 of the HLA-DPB1 gene.

Objective To explore the effects of modified vaginal douche for preventing radiotherapy complications in patients with cervical cancer receiving radiotherapy.Methods Totally 100 patients with cervical cancer receiving radiotherapy were recruited and divided into the experimental group (n=50)and the control group (n=50). The experimental group received vaginal irrigation with modified vaginal douche. The control group received conventional vaginal irrigation.The degree of vaginal cleanliness and the incidence rate of radiotherapy complications were compared between the control group and the experimental group.Results There was a significant difference between the two groups on the degree of vaginal cleanliness (P<0.01). The incidence of vaginitis and vaginal stenosis in the experimental group was 4% and 2%, which was lower than those in the control group (22%, 16%), and the differences were statistically significant (x2=9.890,5.132;P<0.05).Conclusions Compared with traditional vaginal douche,modified vaginal douche is more effective in patients with cervical cancer receiving radiotherapy,and can significantly reduce the incidence of radiotherapy complications.

OBJECTIVETo develop a method for separating the human leukocyte antigen (HLA)-A, -B and -C haploid using biotinylated probes and streptavidin magnetic beads in order to solve ambiguous HLA genotyping results.

METHODSBased on sequence information of HLA alleles from the IMGT/HLA database, the 5-biotinylated probes were designed. The probe was mixed and extended with corresponding genomic DNA, and incubated with streptavidin magnetic beads, which could form a streptavidin magnetic beads-biotin-probe DNA complex. The unique DNA haploid binding to corresponding probe was isolated after washes and elution. The separated haploid genomic DNA was used as template for HLA-A, -B and -C loci amplification and sequencing analysis.

RESULTSAmong the 12 HLA-A probes, 19 HLA-B probes and 13 HLA-C probes, DNA sequencing has confirmed that 9 HLA-A probes, 9 HLA-B probes and 5 HLA-C probes could successfully separate the haploid from genomic DNA samples.

CONCLUSIONThe developed method for HLA-A, -B and -C haploid separation is reliable, which can solve certain ambiguity and improve the accuracy of HLA genotyping.

OBJECTIVE: To study the distribution of KIR3DL2 alleles among ethnic Han Chinese from Zhejiang. METHODS: Genomic DNA was extracted by using a magnetic bead method. The full sequence of the KIR3DL2 gene was amplified with four pairs by PCR primers. The coding regions of 208 unrelated ethnic Han Chinese blood donors were analyzed using a BigDye Terminator v3.1 Sequencing Kit. The genotypes were assigned based on the nucleotide polymorphism of the KIR3DL2 gene. RESULTS: Among the 208 samples, 133 were KIR3DL2 heterozygotes and 75 were homozygotes. Forty six KIR3DL2 genotypes were detected. Respectively, 70, 33 and 23 individuals were found to have a KIR3DL2*00201/KIR3DL2*00201, KIR3DL2*00201/KIR3DL2*00701, and KIR3DL2*00201/KIR3DL2*01001 genotype. Twenty-two KIR3DL2 alleles were discovered, and the frequencies of KIR3DL2*00201, KIR3DL2*00701 and KIR3DL2*01001 were 57.45%, 13.46% and 9.13%, respectively. CONCLUSION The distribution of KIR3DL2 alleles among ethnic Han Chinese in Zhejiang has been determined and fits the criteria for genetic polymorphism.
