Sequence analysis and 3D molecular structure simulation of a novel HLA allele B*51: 159 / 中华医学遗传学杂志

Objective@#To identify a novel human leukocyte antigen (HLA) B allele in a Chinese Han individual and construct its three-dimensional structure.@*Methods@#The initial HLA genotyping was performed by PCR-sequence-based typing (PCR-SBT). The ambiguous allele was confirmed with single-strand DNA sequencing. The DNA sequence was analyzed to identify the difference between the novel allele and its closest matching allele. Finally, the three-dimensional molecular structure of the novel allele was constructed using a Swiss-Model.@*Results@#One allele of the subject at the HLA-B locus was B*44: 03: 01, whilst the other was a novel allele which differed from the closest matching allele B*51: 01: 01: 01 by nucleotide (nt) 329 A>C in exon 2, resulting in an amino acid change at codon 86 (p.Asn86Thr).@*Conclusion@#A novel HLA-B allele has been identified and officially named as HLA-B*51: 159 by the WHO Nomenclature Committee for Factors of the HLA System. The three-dimensional structure of B*51: 159 was simulated.

Effects of Different Acupuncture Therapies on Clinical Efficacy of Acute Cold Type Facial Paralysis / 中国中医药信息杂志

Objective To discuss the clinical efficacy of warm acupuncture, acupoint injection, bloodletting and electroacupuncture, and their interaction effects for acute cold type facial paralysis. Methods Totally of 48 patients with acute cold type facial paralysis were randomly divided into three groups by orthogonal experimental design, and then were assigned to 16 treatment plans. All patients received routine basic treatment, and then were given warm acupuncture, acupoint injection, bloodletting and electroacupuncture according to assigning results. 10 d were as a treatment course, with 2 d as interval, 3 treatment courses in total. The neurological function scores before and after treatment and facial nerve recovery time were recorded. Results There was statistical significance in scores of facial nerve function, warm acupuncture, acupoint injection, electroacupuncture, bloodletting had significant difference with errorterm (P<0.01). There was statistical significance in the recovery time of the facial nerve function, warm acupuncture, bloodletting compared with error term (P<0.01). Conclusion Warm acupuncture, acupoint injection, bloodletting and electroacupuncture combine with acupuncture are better for acute cold type facial paralysis. Warm acupuncture and bloodletting therapy in the acute phase of interventional therapy can shorten the recovery time of facial nerve.

Effect of medicinal charcoal tablets combined with blood purification on renal function, inflammatory mediators, oxygenation index and intestinal barrier function in patients of postoperative severe abdominal infection / 中国生化药物杂志

Objective To investigate the effect of medicinal charcoal tablets combined with blood purification therapy on on renal function, inflammatory mediators, oxygenation index and intestinal barrier function in patients postoperative severe abdominal infection.Methods 65 cases with severe abdominal infection from the hospital were selected and randomly divided into control group (32 cases) and experiment group (33 cases) by random digital table method.The control group were treated by clinical routine therapy and experiment group were treated on the basis of control group with medicinal charcoal tablets combined with blood purification therapy.The renal function, inflammatory mediators, oxygenation index, intestinal barrier function and efficacy were tested.ResuIts Compared with control group after treatment, the renal function of serum creatinine (Scr), blood urea nitrogen (BUM), uric acid (UA) levels were lower (P<0.05), the inflammatory mediators of tumor necrosis factor α(TNF-α), interleukin-6 (IL-6) and interleukin-8 (IL-8) levels were lower (P<0.05), the oxygenation index (OI) was higher(P<0.05), the intestinal barrier function indicators of plasma diamine oxidase (DAO) and endotoxin of lipopolysaccharide (LPS) were lower (P<0.05), the total efficiency were higher (χ2 =3.91, P<0.05) in experimental group.ConcIusion The medicinal charcoal tablets combined with blood purification could effectively improve renal function, reduce inflammatory mediators levels, improve intestinal barrier function, and increase oxygenation index in patients with severe abdominal infection, which has a good clinical curative effect for postoperative severe abdominal infection .

Effect of hongjintian decoction on serum MDA, SOD, NGF, MBP and BFGF levels of exercise-induced fatigue athletes / 中国生化药物杂志

Objective To investigate the effect of Hongjintian decoction on the levels of serum MDA , SOD, NGF, MBP and bFGF of physical fatigue athletes.Methods 40 students of physical education college were randomly divided into experimental group and control group, 20 cases in each group.After the end of sport, the experimental group were given Hongjintian decoction, and control group were given sugar water, the levels of serum MDA, SOD, NGF, MBP and BFGF in two groups were detected.ResuIts Compared with control group, the level of MDA in experimental group was lower(P<0.05), and the level of SOD was higher (P<0.05); NGF and BFGF levels were higher in experimental group(P<0.05), MBP level was lower (P<0.05).ConcIusion Hongjintian decoction can significantly reduce serum MDA, MBP levels, increase serum SOD, NGF and BFGF levels of physical fatigue athletes.

Objective To analyze the distribution of HLA-C alleles in Shandong Han population of China.Methods One hundred and fifty unrelated potential donors,self-claimed as Han population from Shandong province,were selected from China Marrow Donor Program.Genotypes of HLA-C with the donors were identified by PCR-SBT.The frequencies of allele were calculated with direct counting method and the differences with other populations were analyzed with SPSS16.0 x2 software.Results A total of 25 alleles of HLA-C were observed and the most common alleles were C * 06:02 and C * 07:02 with the frequency of more than 10.00％.Moreover,there were 16 kinds of alleles with the frequency of more than 1.00％ accounting for 95.33％ of the total alleles.The distribution of HLA-C alleles in Shandong Han population was similar to that in northern Han population,but had some differences with that in southern Han population.In addition,the distribution of HLA-C alleles in Shandong Han population significantly differed from that of German/African American.Conclusion This study on the distribution of HLA-C alleles in Shandong Han population provides valuable references for further studies on the genetics of HLA,cross-match for organ transplantation and other genetic-associated diseases in this population.

Association of killer cell immunoglobulin-like receptor genes 2DS4 and its variant KIR1D with syphilis / 中华微生物学和免疫学杂志

Objective To investigate the killer cell immunoglobulin-like receptor (KIR) genes, KIR2DS4 and its variant KIR1D for an association with syphilis in the comparison between syphilis patients and unrelated healthy subjects. Methods One hundred and ninety syphilis patients and 192 unrelated healthy subjects were performed to determine the KIR genotypes by PCR-SSP method. The gene frequencies of KIR2DS4 and KIR1D were analyzed for an association with syphilis in the patients and healthy people who belonged to KIR gene haplotype A. Results Of 192 healthy individuals, 187 were identified with a KIR2DS4 gene. And 91 individuals were classified as homozygous haplotype A with the percent of 48.7% (91/187) in 187 KIR2DS4 positive individuals. Of 190 syphilis patients, 181 were identified with a KIR2DS4 gene. And 89 individuals were classified as homozygous haplotype A with the percent of 49.2% (89/181) in 181 KIR2DS4 positive individuals. The frequency of KIR1D/KIR1D in syphilis patients classified as haplotype A was 16.9%, and was significantly higher than that in the control group (6.6%, P=0.032). However, there was no significant difference for the frequencies of KIR2DS4/KIR2DS4 and KIR2DS4/KIR1D between the two groups (P>0.05). Conclusion KIR1D/KIR1D might be associated with syphilis in the comparison between syphilis patients and unrelated healthy controls who were classified as homozygous haplotype A.
