Objective To establish a real-time quantitative reverse-transcription PCR ( qRT-PCR) method for detection of hepatitis E virus ( HEV) of different genotypes based on standard HEV DNA plasmid in order to promote its application in clinical laboratory. Methods Specific primers and probe of HEV were designed based on the conserved open reading frame 3 (ORF3) regions. HEV DNA plasmids were construc-ted and 10-fold serial dilutions of the plasmids were prepared and used as standards to establish one-step qRT-PCR. The established method was compared with HEV antigen, antibody and RT-nPCR assays. Some positive samples were sequenced and analyzed by evolutionary tree. Results The one-step qRT-PCR meth-od for HEV detection in serum or feces samples was successfully establish. It could reach a sensitivity of 25 copies/test and 77. 8% of its results were consistent with those by HEV antigen assay. Nine patients were infected with HEV of genotypes 4a, 4d or 4n as indicated by evolutionary tree. Conclusion The HEV qRT-PCR method based on its standard plasmid is successfully established, which paves the way for commercial-ization of clinical applications.

Objective To evaluate the CT findings of lymphofollicular thymic hyperplasia in adult myasthenia gravis (MG).Methods The CT findings of thymus area of 134 adult patients with lymphofolficular thymic hyperplasia in MG were reviewed,all of them with surgically and histologically proven diagnosis,and compared with the CT findings of 165 normal subjects.Results In the group of patient,CT showed enlargement of thymus in 31 patients,5 patients had nodule or mass(＜3 cm);thus 36 cases(26.9%)can confirmed diagnose by CT with thymic hyperplasia.CT showed 2 masses(＞3 em) and 9 patients(6.7%)had normal size thymus with soft-tissue density,it can considered with thymic hyperplasia.The spotty or streak shadow showed in other patients,though it could not be certain diagnosed as thymic hyperplasia,but could not be except it.The thymus area tissue complete replacement by fatty density were not found in patient group.The CT findings of patients had marked difference when compared with group of normal subjects(P＜0.01),except the spotty or streak shadows.Conclusion CT scan is an important method in diagnosing thymic lymphofollicular hyperplasia of MG in adult.

OBJECTIVETo investigate changes in serum insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-binding protein-3 (IGFBP-3) and their significance in children with left-to-right shunt congenital heart disease (CHD) associated with heart failure (HF).

METHODSTwenty healthy children (control group), 20 children with HF, without basic heart disease (HF group), 20 children with left-to-right shunt CHD, without HF (CHD group), and 30 children with left-to-right shunt CHD associated with HF (CHD+HF group) were included in the study. These groups were compared in terms of serum IGF-1 and IGFBP-3 levels. According to the New York Heart Association (NYHA) Functional Classification, the CHD+HF group was further divided into NYHA-II, NYHA-III and NYHA-IV subgroups and the subgroups were compared in terms of serum IGF-1, IGFBP-3, and cardiac troponin I (cTnI) levels. The correlation of serum IGF-1 and IGFBP-3 levels with serum cTnI level in the CHD+HF group was analyzed.

RESULTSThe CHD group showed decreased serum IGF-1 and IGFBP-3 levels compared with the control group (P<0.01). The CHD+HF group showed a significantly decreased serum IGF-1 level compared with the control group (P<0.01) and CHD group (P<0.05). The HF group had significantly increased serum IGF-1 and IGFBP-3 levels compared with other groups (P<0.01). The NYHA-II subgroup had the highest serum IGF-1 level and the NYHA-IV subgroup had the lowest serum IGF-1 level (P<0.01). In the CHD+HF group, serum IGF-1 and IGFBP-3 levels were negatively correlated with serum cTnI level (r=-0.692, P<0.05; r=-0.530, P<0.05).

CONCLUSIONSSerum IGF-1 level can be used as an objective condition evaluation indicator for CHD, and low serum IGF-1 level is a risk factor for HF. This also provides a clinical basis for treatment of HF using exogenous IGF-1.

The group X meningococcal disease is rare in China and developed countries.No related cases have been reported in Human Province.The disease progresses rapidly and leads to critical severity.Serious complica-tions may occur,if not treated actively.Group X Neisseria meningitidis(Nm X)vaccine has not yet obtained per-mission at present.This paper collects data on the symptoms,signs,auxiliary examinations,and treatment process of the first patient with severe group X meningococcal disease in Hunan Province,reviews relevant literatures,so as to improve clinicians'understanding on group X meningococcal disease,conduct early identification,diagnosis and treatment of the disease.

Objective To investigate the changes and clinical significance of peripheral blood mucosal-associated invariant T(MAIT)cells in children with influenza.Methods Children with influenza who received treatment in the outpatient and inpatient departments of a children's hospital from January to May 2023 were selected and divided into the common type group and the severe type group.Healthy children who underwent physical examination in this hospital during the same period were selected as the healthy control group.Within 24 hours after admission,children's venous blood was drawn for testing;ratios of MAIT cells(CD3+CD161+TCRVα7.2+cells)and MAIT cells expressing PD-1,CD69,perforin,and CD107 α were tested by flow cytometry,respectively.Differences among all the groups were compared.Results Compared with the control group,the proportion of peripheral blood MAIT cells in children with common and severe influenza gradually decreased,while the proportion of CD69-ex-pressing and perforin-positive MAIT cells increased gradually.Differences were statistically significant(all P＜0.05).There was no statistically significant difference in the proportion of MAIT cells expressing CD107(P＞0.05).The proportion of PD-1 positive MAIT cells increased(P＜0.05),but there was no statistically significant difference be-tween the common type and severe type groups(P＞0.05).Conclusion The decrease of peripheral blood MAIT cells accompanied with immune activation plays a role in the pathogenesis of influenza.

BACKGROUNDInflammation plays a pivotal role in the formation and progression of ischemic stroke. Recently, more and more epidemiological studies have focused on the association between C-reactive protein (CRP) -717A > G and -286C > T > A genetic polymorphisms and ischemic stroke. However, the findings of these researches are not conclusive.

METHODSWe performed a meta-analysis to determine whether these two polymorphisms are associated with the risk of ischemic stroke. Eligible studies were identified from the database of PubMed, Medline, Embase, Web of Science, CNKI, Weipu, and Wanfang. We calculated odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association.

RESULTSFour articles were included in our study, including 1926 cases and 2678 controls for -717A > G polymorphism, 652 cases and 1103 controls for -286C > T > A polymorphism. The results of meta-analysis showed that single nucleotide polymorphism (SNP) -717A > G was not significantly associated with the risk of ischemic stroke (GG vs. AA, OR = 1.12, 95% CI = 0.83-1.50, P = 0.207; GG + GA vs. AA, OR = 1.04, 95% CI = 0.93-1.17, P = 0.533; GG vs. GA + AA, OR = 1.10, 95% CI = 0.82-1.47, P = 0.220). Meta-analysis of SNP - 286C > T > A also demonstrated no statistical evidence of a significant association with the risk of ischemic stroke (AA vs. CC, OR = 0.86, 95% CI = 0.59-1.25, P = 0.348; AA vs. CC, OR = 0.92, 95% CI = 0.80-1.06, P = 0.609; AA vs. CC, OR = 0.89, 95% CI = 0.62-1.30, P = 0.374).

CONCLUSIONSThis meta-analysis demonstrated little evidence to support a role of CRP gene -717A > G, -286C > T > A polymorphisms in ischemic stroke predisposition. However, to draw comprehensive and more reliable conclusions, further larger studies are needed to validate the association between CRP gene polymorphisms and ischemic stroke in various ethnic groups.

Objective: To observe the clinical efficacy of auricular point pricking-bloodletting plus auricular point sticking therapy for acne vulgaris. Methods: A total of 66 patients with acne vulgaris were randomized into an observation group and a control group by the random number table, with 33 cases in each group. The observation group was treated with auricular point pricking-bloodletting plus auricular point sticking therapy, and the control group was treated only with auricular point sticking therapy. The treatments of both groups were performed twice a week, 4 weeks as a course of treatment, for 3 courses in total. The scores of skin lesions and dermatology life quality index (DLQI) scores were recorded before and after treatment to assess the clinical efficacy. Results: During the trial, there were 3 cases of drop-out both in the observation group and the control group. After 3 courses of treatment, the total effective rate of the observation group was 96.7％, while that of the control group was 76.7％. The difference between the two groups was statistically significant (P<0.05). The intra-group comparison showed that the scores of skin lesion and DLQI were both decreased with the increase of treatment times, that was, the scores were lower than those at the previous time point (allP<0.05). After 1, 2, and 3 courses of treatment, the scores of skin lesion and DLQI of both groups were statistically different from those of the same group before treatment (allP<0.05). At every time point during the treatment, the scores of skin lesion and DLQI of the observation group were lower than those of the control group, and the differences between the two groups were statistically significant (all P<0.05). Conclusion: Auricular point pricking-bloodletting plus auricular point sticking has a better curative effect than auricular point sticking therapy alone in the treatment of acne vulgaris, and has a time-effect correlation.
