Objective To investigate the significance of blood donation in preventing metabolic syndrome (MS)by analyzing the changes of the blood pressure and the related biochemical indexes before and after blood donation in the blood donors with high risk of MS.Methods The blood specimens of 102 blood donors,aged 45 -55 years old with the systolic blood pressure of 110 -140 mmHg and the diastolic blood pressure of 75 -90 mmHg,the body mass index> 24 kg/m2 ,were selected as the subjects.The blood pressure,heart rate,iron reserves,blood glucose,blood lipids,and the other indicators were determined before blood donation. All the above indicators were tested again on 42 d after blood donation.Results The blood pressure,iron reserves,blood glucose and LDL/HDL ratio after donation showed significant changes compared with before blood donation(P <0.05 ).Conclusion The changes of the MS related blood indexes exist before and after blood donation,blood donation has a certain significance for preven-ting MS in the blood donors with high risk of MS.

Objective To evaluate the value of bronchoscopy specimens' microRNA-21 (miRNA-21) and microRNA-431 (miRNA-431) in the development and prognosis of pulmonary tuberculosis. Methods A total of 43 confirmed pulmonary tuberculosis patients admitted to Shaanxi Provincial Tuberculosis Prevention Hospital from May 2022 to July 2023 were included as the study group, and 43 healthy volunteers during the same period were included as the control group. In the study group, the severity of lung lesions was classified as mild in 14 cases, moderate in 19 cases, and severe in 10 cases. According to the prognosis, patients were divided into poor prognosis and good prognosis groups. The miRNA-21 and miRNA-431 levels of patients with different disease severity and prognosis in the study group and the control group were compared, and the factors affecting the development and prognosis of tuberculosis were analyzed by logistic multivariate analysis, and a prediction model for the development and prognosis of tuberculosis was established. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the predictive value of the model. Results The levels of miRNA-21 and miRNA-431 in the study group were significantly higher than those in the control group, and the difference between groups was statistically significant (P<0.05). In the study group, the levels of miRNA-21 and miRNA-431 were positively correlated with the severity of the disease, and the levels in severe pulmonary tuberculosis patients were significantly higher than those in mild and moderate pulmonary tuberculosis patients, with statistically significant differences between the groups (P<0.05). In the study group, the levels of miRNA-21 and miRNA-431 in patients with pulmonary tuberculosis with poor prognosis were significantly higher than those in patients with pulmonary tuberculosis with good prognosis, with statistically significant differences between the groups (P<0.05). Using miRNA-21 and miRNA-431 expression as independent variables, and the development and prognosis of pulmonary tuberculosis as dependent variables, logistic regression analysis was performed. The results showed that the high expression of miRNA-21 and miRNA-431 were both influential factors for the development and prognosis of pulmonary tuberculosis (P<0.05). The ROC curve analysis showed that the optimal cutoff value of the prediction model was 0.0895, and the area under the curve (AUC) of miRNA-21, miRNA-431 and combined were 0.614 (0.651-0.732), 0.671 (0.686-0.811), and 0.891 (0.787-0.993). Conclusions The high expression levels of miRNA-21 and miRNA-431 in patients with tuberculosis are closely related to the development of the disease and can predict the prognosis of patients with tuberculosis to a certain extent. The comprehensive application value of combined diagnosis is high, and it is recommended to promote clinical use.

Objective To detect the expression of SSX and to correlate it with clinical indicators of primary hepatocellular carcinoma (HCC).Methods The expression of SSX1-5 mRNA and SSX1 protein were respectively detected by RT-PCR and Western blot and immunohistochemistry staining.The relation between the expression of SSX mRNA and SSX1 protein with clinical indicators were analysed.Results SSX1,SSX2,and SSX3 mRNA were expressed in hepatocellular carcinoma cell lines BEL-7404,Hep G2,and SMMC-7721.In 26 HCC samples,SSX1-SSX5 mRNA was detectable in 53.8％,42.3％,50.0％,46.2％ and 26.9％.The expression of SSX1 mRNA was not related to serum AFP levels (P ＞0.05).Specific expression was both found in the normal group and the high value group.The expression rate of SSX1 mRNA was 85.7％ in the older group,which was higher than in the younger group (16.7％,P ＜ 0.05).The expression rate of SSX1 protein was 50％ in HCC tissues,which was not seen in the caner-adjacent or cirrhosis tissues.In 49 HCC paraffin tissue section samples,the expression rate of SSX1 protein was higher than that in caner-adjacent tissues (46.9％ vs 18.4％,P ＜ 0.05).The expression rate of SSX1 protein was 68.3％ in the large hepatocellular carcinoma group,which was higher than in the small hepatocellular carcinoma group (29.6％),(P ＜ 0.05).Conclusions SSX1 mRNA is expressed with a high percentage and specificity in HCC and their products are new potential promising targets for antigen-specific immunotherapy of HCC.The detection of SSX1 expression has the potential value for auxiliary diagnosis of HCC.

BACKGROUND:During the research of ABO blood type antigen, the overwhelming majority samples of same ABO gene express a normal and same ABH antigen. But a certain amount samples with the same ABO genetic background show different antigen intensity expression as for different family or individuals. The ABO blood type has complex expression regulation mechanism. Analysis of ABO blood group serology and genetic background of these rare bi-specific AB phenotype specimens, and further studying on epigenetics may partly revealed ABO gene expression mechanism. OBJECTIVE:To study methylation of CpG island and explore the relationship between ABO gene promoter coding glycosyltransferase with dual donor specificity and ABH antigen expression. METHODS:Six samples detected as CisAB or B(A) phenotype were studied in this paper. The whole code sequences and promoter sequence of ABO gene were amplified respectively. The level of CpG methylation in promoter of ABO gene was further detected with bisulfite treatment method. RESULTS AND CONCLUSION:Among the six bi-specific AB phenotype samples, two previously-identified CisAB05/B(A)06 al eles with nt803C>G on the basis of B101 al ele sequence could be seen, and three additional methylated sites nt-33(30%), nt+27(50%) and nt+49(50%) were found between the two regions of CpG island in promoter of ABO gene. Two CisAB01 al eles with nt803C>G mutation on the basis of A101 sequence were found at nt-26C(10%). Other two B(A)04 al eles contained nt640A>G mutation on the basis of B101 sequence were found in the whole code sequences regions, and six additional methylated sites nt-33(10%), nt+16(50%), nt+57(60%), nt+59(60%), nt+68(60%) and nt+74(60%) were found between the two samples. No abnormity was identified in the promoter region of ABO gene. Our results indicated that the differential methylation levels in the CpG island of ABO gene promoter region may affect ABH antigens expression on the red cel membrane even if the samples had the same ABO genetic background.

Objective To explore the clinical effects of aminophylline on bronchiolitis in children.Methods One hundred and twen-ty-eight children with bronchiolitis in our hospital were randomly divided into the experiment and treated control group,in the meantime,and divided into the severe and mild group according to their condition.The children in control group were treated with traditional methods,in experiment group were treated with aminophylline(2 mg/kg,every day one time),as well as used traditional methods.All patients in 2 groups were checked by volume (VT), inhale time and exhale time ratio (Ti/tE),time to peak expiratory flow and expiratory time ratio(tPTEF/Te),time to peak expiratory flow to total expiratory time and volume ratio(vPTEF/vE) respectively. Meanwhile pulmonary function,alkyla-denine glycosylase in trachea secretion,IL-8,cytotaxonomy in trachea secretion on time,after the third day and the 7th day.Their curative effects were evaluated.All parameters were analyzed by statistical methods.Results Cytotaxonomy of the patients in the experiment were more improved than that of control group(P
