Objective To compare PCR-SBT to IMS-ELISA in the HLA-B27 detection in the ankylosing spondylitis (AS)pa-tients.Methods Simultaneously,PCR-SBT and IMS-ELISA were used to detect the HLA-B27 expression in peripheral blood samples which were suspected patients with AS from 120 cases.Chisquare test of paired design and the area under curve of receiver operating characteristics of SPSS17.0 software were used to evaluate the value of PCR-SBT and IMS-ELISA in HLA-B27 detection of AS patients.Results Among 120 cases of suspected patients with AS,the positive rates of HLA-B27 detected by PCR-SBT and IMS-ELISA were 45.83%(55/120)and 37.50% (45/120),respectively.There was statistical difference between the two methods in the HLA-B27 detection (χ2 =59.455,P =0.000).The sensibility and spe-cificity of PCR-SBT were 96.36% and 96.92%,respectively.While the sensibility and the specificity of IMS-ELISA were 69.09% and 89.23%,respectively.Area under the curve of two methods were 0.966 and 0.792,respectively.Conclusion In comparison with IMS-ELISA,the sensibility and the specificity of PCR-SBT in HLA-B27 detection were higher in AS diag-nosis,that is to say,PCR-SBT is better in HLA-B27 detection and AS diagnosis.

Objective To investigate whether expression quantity of HLA-B27 and its subtypes associated with incidence of AS,the gene expression of HLA-B27 and its subtypes were detected in patients with AS.Methods 120 cases patients sus-pected with AS and 50 healthy subjects were enrolled in the study.Main demographic and clinical characteristics of the sub-jects were collected.Meanwhile total RNA was isolated from peripheral blood and real time RT-PCR was used to measure the quantitative expression of HLA-B27 gene.Besides RT-PCR,sequence-based typing (SBT)method was used to confirm the HLA-B27 subtype.All experimental data were analyzed by SPSS17.0 software and P values <0.05 were considered to be significant.Results Firstly,there were 55 subjects were finally diagnosed as AS patients among the 120 patients suspec-ted with AS.There were 53 subjects whose HLA-B27 was positive (96.36%)in 55 patients with AS.It showed that there was a correlation between BASDAI and expression quantity of HLA-B27 gene (r=0.845,P =0.000).Five subtypes were found and which were HLA-B27∶04 subtype (29/53,54.72%),HLA-B27:05 subtype (20/53,37.74%),HLA-B27 ∶02 subtype (2/53,3.77%),HLA-B27∶03 subtype (1/53,1.89%)and HLA-B27∶07 subtype (1/53,1.89%),respectively. Among the 50 healthy subjects,there were only one kind of subtype (2/50,4%),which was HLA-B27∶04.There were no statistical difference in the age (t=0.711,P =0.480),sex (χ2 =0.880,P =0.348),family history (χ2 =0.011,P =0.916) and treatment (χ2 =0.113,P =0.736)between the HLA-B27∶04 and HLA-B27∶05 subtypes.Conclusion HLA-B27∶04 and HLA-B27∶05 were primary subtypes in AS patients which HLA-B27 positive.There was a correlation between gene expression quantity of HLA-B27 and AS disease activity index.

Objective: To observe the effects of recombinant adenovirus TRAIL (AdS-TRAIL & Ad5F35-TRAIL) on apoptosis of non-small cell lung (NSCLC) cells, so as to assess the value of Ad-TRAIL in gene therapy of NSCLC. Meth-ods: CAR and CD46 expression levels in lung cancer cell lines (A549, Z793, QG56 and NCI-H520) and the primary lung cancer cells from samples of 10 NSCLC patients were assayed by flow cytometry analysis. The lung cancer cell lines and primary lung cancer cells were infected with Ad5-TRAIL & Ad5F35-TRAIL adenoviral vectors at MOI 10 or 50, re-spectively; the percentage of apoptosis cells labeled by Annexin V-FITC in different cells were measured by flow cytometry 48 h after transfection. Results: The expression of CD46 were higher than that of CAR in all the lung cancer lines (A549, Z793, QG56 and NCI-H520) and the primary lung cancer cells. Significant apoptosis was observed in Z793 and QG56 cells transfected with Ad5-TRAIL or Ad5F35-TRAIL at MOI 10, with the apoptosis rate being (1.76±2.10)% (Ad5-TRAIL), (15.96±2.89) % (Ad5F35-THAIL) and (6.05±1.58) % (Ad5-TRAIL), (10.11±1.26) % (Ad5F35-TRAIL), respectively, compared to no adenovirus-transfected cells ([2.33±0.37] % and [5.95±1.89]%, respectively, P < 0.05). Less than 10% of apoptosis cells were detected in NCI-H520 cells transfected with Ad5- or Ad5F35-TRAIL at MOI 50 ([12.89±3.2] % for AdS-TRAIL and [9.08±1.35]% for Ad5F35-TRAIL, respectively) compared to no adenovirus-transfected cells ([7.04±2.17] %, P > 0.05). Moreover, apoptosis induced by Ad5- or Ad5F35-TRAIL transfection in A549 cells was not detected both at MOI 10 and 50. About half of the primary lung cancer cells from 10 patients induced apoptosis after transfected with Ad5-TRAIL or Ad5F35-TRAIL vector. A higher percentage of apoptotic cells were found in Ad5F35-TRAIL group than those in Ad5-TRAIL and control groups. Conclusion: Ad5-TRAIL can induce apoptosis of NSCLC cells in vitro, and Ad5F35-TRAIL is more potent than Ad5-TRAIL, so Ad5F35-TRAIL is more suitable for gene therapy of NSCLC.

Objective To explore the clinical efficacy of motor imagery therapy in treating neurogenic bladder dysfunction after traumatic spinal cord injury (SCI).Methods Seventy patients with neurogenic bladder control problems after SCI were randomly divided into an experimental group and a control group using a random number table.All patients of the two groups were given general bladder function intervention,including intermittent catheterization,inducing voiding by reflex detrusor contraction,Credé's maneuver urination,etc.Additionally,the patients in the experimental group were given supplemental motor imagery therapy.The times of urinary incontinence,average bladder capacity,maximum voided volume and residual urine volume of the two groups were measured before treatment and at 2 months after treatment.The two groups' outcomes were quantified using a quality of life (QOL) score.Results Incidents of urinary incontinence,average bladder capacity,residual urine volume,voided volume and the QOL score showed significant improvements in both groups,but the experimental group showed better improvements than the control group.The differences were statistically significant.Conclusion The combination of general bladder function intervention with motor imagery therapy can improve the voiding function of patients with neurogenic bladder disorders after SCI more significantly and enhance their QOL.

Objective To compare the serological non-invasive liver fibrosis tests and pathological examination in the clinical diagnosis of chronic hepatitis B. Methods Selected 97 patients with chronic hepatitis B in our hospital as the research object and tested non-invasive liver fibrosis tests and liver biopsy pathological examination.Compare the test results of two kinds. Results The serum noninvasive hepatic fibrosis index(PⅢP,Ⅳ-C,HA,LN)showed good positive correlation with pathological stage. The correlation coefficient suggested that with the aggravation of hepatic fibrosis,liv-er fibrosis indexes tended to rise gradually,and the indicators differences were statistically significant (P<0.05). Con-clusion Liver biopsy in patients with chronic hepatitis B diagnosis detection is the "gold standard" with greater injury. Serological non-invasive liver fibrosis tests has high diagnostic value,can reduce the number of puncture biopsy.

Objective:To analyze the clinical curative effect of protective sleep nursing on neonatal hyperbilirubinemia.Methods:Eight neonates with hyperbilirubinemia who were admitted from April 2019 to August 2019 were enrolled. They were divided into control group (40 cases) and observation group (40 cases) by random digits table method. Both groups were given routine nursing. On basis of control group, observation group was given protective sleep nursing. The clinical effect, sleep time, discomfort reactions and nursing satisfaction were compared between the two groups.Results:After nursing, the sleep time, crying time and bilirubin level were (18.67 ± 1.45) h/d, (0.82 ± 0.12) h/d, (191.58 ± 12.74) μmol/L in the observation group, and (17.63 ± 1.33) h/d, (1.05 ± 0.15) h/d, (202.42 ± 13.08) μmol/L in the control group, there were significant differences between the two groups ( t values were 3.343, 7.573, 3.755, P<0.05). The duration and regression time of jaundice were (5.26±1.24), (8.70±2.12) d in the observation group, and (7.14±1.18), (12.95±2.31) d in the control group, there were significant differences between the two groups ( t values were 6.946, 8.573, P<0.05). The good rate of sleep quality, incidence rates of vomiting, skin damage and needle falling out, and nursing satisfaction rate were 90.00%(36/40), 7.50%(3/40), 5.00%(2/40), 10.00%(4/40), 100.00%(40/40) in the observation group, and 72.50% (29/40), 27.50%(11/40), 22.50%(9/40), 32.50%(13/40), 87.50%(35/40) in the control group, there were significant differences between the two groups ( χ2 values were 4.021-6.050, P<0.05). Conclusions:The application of protective sleep nursing in treatment of neonatal hyperbilirubinemia can effectively prolong their sleep time, improve their sleep quality, which is conducive to improving their symptoms, reducing discomfort reactions.And satisfaction of their family members is relatively higher.

Objective:To investigate the ability of the anti-PD-1(scFv)/hIL-15 fusion protein(PD-15) to specifically bind to PD-1 in vitro and the effect of the combination of PD-15 with GF-hIL-15Ra-K562(G15Ra-K562) feeder cells to expand NK/T cells. Methods:Overlap PCR was used to construct G15Ra expression vector. pMXs-G15Ra-IP was transfected into K562 by electroporation. G15Ra-K562 feeder cell lines were obtained by limiting dilution method. pUC57-PD-15 was constructed by digestion and ligation. Lipofectamine? 2000 was used to transiently transfect pUC57-PD-15 into HEK293T cells and the conditioned medium containing PD-15 fusion protein was obtained. Density gradient centrifugation was used to obtain human peripheral blood mononuclear lymphocytes(PBMC), and CFSE staining was used to mark active proliferating cells. Flow cytometry was used to detect the ability of PD-15 to specifically bind to PD-1 and its effect on the proliferation of human PBMC and the proportion of different subpopulations of lymphocytes.Results:The feeder cells G15Ra-K562 with high expression of fusion protein G15Ra was successfully constructed. The addition of hIL-15 can increase the ability of G15Ra-K562 to expand human PBMC by more than 5 times( P<0.05). PD-15 fusion protein has PD-1 specific binding ability( P<0.001), combined with G15Ra-K562 can efficiently expand human peripheral blood-derived NK/T cells in vitro( P<0.05). The cells expanded by PD-15 and G15Ra-K562 are mainly natural killing cell, CD8 + T and CD4 + T cells. Conclusions:The PD-15 fusion protein can specifically target the PD-1 molecule and has a strong human peripheral blood-derived NK/T cell expansion ability when combined with G15Ra-K562 feeder cells. These results shed light on selective expansion of PD-1 + lymphocytes in vitro.
