Objective To observe the relationship between homocysteine (Hcy),C-reactive protein (CRP) and type 2 diabetes peripheral vascular disease (PVD).Methods Fifty-eight patients with type 2 diabetes according to the condition of PVD were divided into simple type 2 diabetes mellitus group (DM group,30 cases) and PVD group (28 cases).Twenty-five healthy people were chosen at the same period as control group.The fasting blood glucose (FBG),glycosylated hemoglobin (HbA1c),total cholesterol(TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C),Hcy and CRP levels were detected among 3 groups,and the body mass index (BMI),ankle brachial index(ABI) was calculated.Results The BMI,TG,TC and HDL-C levels among 3 groups had no statistical significance (P ＞0.05).The FBG,HbA1c and LDL-C in DM group and PVD group were significantly higher than those in control group [(7.54 ± 1.25),(8.12 ± 1.57) mmol/L vs.(4.68 ±0.54)mmol/L; (6.92 ± 0.89)％,(7.54 ± 0.97)％ vs.(4.80 ± 0.54)％ ; (3.79 ± 0.73),(4.41 ± 0.93) mmol/L vs.(2.68 ± 0.54) mmol/L],and the difference was statistically significant (P ＜ 0.05).But the difference between PVD group and DM group had no statistical significance (P ＞ 0.05).Hcy and CRP in DM group and PVD group were higher than those in control group [(10.26 ± 3.62),(19.83 ± 5.54) μ mol/L vs.(8.92 ± 2.41)μ mol/L; (4.12 ±0.57),(5.47 ±0.85) mg/L vs.(2.73 ±0.54) mg/L],ABI was lower than that in control group(0.92 ± 0.18,0.81 ± 0.16 vs.1.02 ± 0.23),and the difference was statistically significant (P ＜ 0.05);Hcy,CRP in PVD group were obviously higher than those in DM group,ABI was lower than that in DM group,and the differences were statistically significant (P＜ 0.05).Spearman analysis showed that Hcy was negatively correlated with ABI (r =-0.635,P ＜ 0.05),CRP was negatively correlated with ABI (r =-0.529,P ＜ 0.05),and Hcy was positively correlated with CRP (r =0.528,P ＜ 0.05).The partial correlation analysis results showed that Hcy and ABI still showed a negative correlation (r =-0.315,P ＜ 0.05),CRP and ABI still showed a negative correlation (r =-0.243,P ＜ 0.05).Conclusion Hcy and CRP participating in the occurrence and development of type 2 diabetes PVD,can be used as a predictor of type 2 diabetes PVD.

Objective To determine the roles of thymic stromal lymphopoietin receptor (TSLPR) and its antibody in airway inflammatory response in asthmatic mice, and to promote maturation and activation of dendritic cells (DCs) in mouse airway. Methods BALB/c mice were randomly divided into group A, B and C. The mice in group B and C were intraperitoneally injected with OVA for allergization while the mice in group A were intraperitoneally injected with PBS as the normal control. The mice in group B and C were treated by inhalation of non-specific IgG and TSLPR IgG respectively, before provocation of asthma using OVA. The bronchoalveolar lavage fluid (BALF) of the mice in different groups were collected for cell differential counts and quantitative detection of IL-4, IL-5, IFN-γand IL-10 levels by ELISA. Moreover, the pulmonary tissue specimens of the mice were collected for pathological examination, and the numbers and phenotypes of DCs from the local lymph nodes and pulmonary tissue were determined by flow cytometry. Results The levels of all the tested cytokines in the BALF from mice in group B and C were remarkably higher compared to those from mice in group A (P<0.01). However, both the IL-4 and IL-5 levels in the BALF from group C mice that pre-blocked with TSLPR IgG were lower than those from group B (P<0.05, P<0.01), whereas both the IFN-γ and IL-10 levels in the BALF from group C mice were higher than those from group B (P<0.05, P<0.01). Furthermore, the numbers of total cells, eosinophils and lymphocytes in the BALF from group C mice were also lower than those from group B (P<0.01). A large number of inflammatory cell infiltration around the bronchus, beaker cell proliferation and mucous secretion reinforcement could be found in the samples from group B mice, while slight inflammatory cell infiltration and beaker cell proliferation in the samples from group C mice. The numbers of DCs in mediastinal lymph node and the levels of I-Ad, CD40, CD80 and CD86 expression of pulmonary DCs from group B mice were higher than those from group C mice (P<0.05). Conclusion TSLP/TSLPR have an effect on promoting asthma, which is closely relative to its regulation of DCs activation. And the interference of TSLPR antibody can decrease the effect of TSLP/TSLPR which indicating a potential of the antibody as a novel anti-asthma drug.

Objective To explore the clinical effects of enema combined with massage therapy on jaundice in premature infants.Methods Seventy-five premature infants with jaundice were randomly divided into 3 groups,enema combined message therapy group(group A),abdominal massage therapy group(group B),and double-side phototherapy group(group C).All 3 groups were received the same formula fee-ding,intravenous nutrition and identical drug treatment.Group A was given enema with mixed kaiselu and normal saline together with 60 times clockwise abdominal massage once a day for 2 weeks.Group B only received abdominal massage twice per day for 2 weeks.Transcutaneous bilirubin(TB) indexes of all the premature infants in the 3 groups were detected and transformed into total TB concentrations every morning,through version of MINOLTA JM-102 transcutaneous bilirubin radiometer made in Japan.When TB index counted more than 196.58 ?mol/L,group A and B were given single-side phototherapy for 24 hours.Neither enema nor abdominal massage was given to group C,and double-side phototherapy was applied when TB indexes were above 196.58 ?mol/L.Daily TB indexes,duration of jaundice and phototherapy,time of meconium exhaustion,defecation times in each day,incidence of constipation and feeding intolerance were recorded.Results Duration of jaunhospitalized and phototherapy were significantly shortened in group A compared with those of the other groups.In 34 premature infants who were hospital for at least 2 weeks,TB indexes in group C were lower than those in group B on the 9th day.On the 12th day and the 14th day,TB indexes in group A and C were lower than those in group B(Pa

Objective To investigate demographic factors implicated in the functional maturation of autologous arteriovenous fistula in a population of patients with end-stage renal disease. Methods The data of 335 consecutive patients with end-stage renal disease who were performed autologous arteriovenous fistula from January 2010 to December 2015 were analyzed retrospectively. The parameters affecting autologous arteriovenous fistula functional maturation were screened. Results Overall arteriovenous fistula functional maturation rate was 78.14%(218/279). The arteriovenous fistula functional maturation rate was 68.33%(82/120) in diabetes and 85.54%(136/159) in non-diabetes, and there was significant difference (χ2=11.844, P<0.01). The arteriovenous fistula functional maturation rate was 62.26%(33/53) in hypoproteinemia and 81.86%(185/226) in non-hypoproteinemia, and there was significant difference (χ2=9.648, P<0.01). Diabetes and hypoproteinemia were the risk factors to promote functional maturation (OR=6.003, 8.476). The arteriovenous fistula functional maturation rate was 87.10%(81/93) in calcium channel blockers using and 73.66%(137/186) in non-calcium channel blockers using, and there was significant difference (χ2=6.556, P<0.05). Calcium channel blockers was the protective factor for promoting functional maturation (OR=0.086). Conclusions Diabetes and hypoproteinemia are found to be associated with functional non-maturation, while calcium channel-blocker agents are associated with better functional maturation.

BACKGROUND:Osteogenic differentiation is a complex process involving transcriptional and post-transcriptional regulation by multiple signaling pathways, and the specific mechanisms remain unclear. It is of great significance to study the role of critical miRNAs in the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) in the treatment of osteoporosis and bone defects. OBJECTIVE: To explore the regulatory ability of miR-21/Sprouty1 function axis in the osteogenic differentiation of BMSCs in patients with postmenopausal osteoporosis. METHODS:BMSCs were isolated from healthy people (H-hBMSCs) and patients with postmenopausal osteoporosis (PMOP-hBMSCs), and their osteogenic ability was compared. Expression of miR-21 and Spry1 at gene and protein levels was detected by real-time RT-PCR and western blot assay, respectively. miR-21 expression was upregulated via transfection in PMOP-hBMSCs, and the osteogenic ability and Spry1 expression of the cells were detected, while real-time RT-PCR and western blot were used to detect the expression of osteogenic marker genes, Runx2 and Osterix. RESULTS AND CONCLUSION:Compared with H-hBMSCs, PMOP-hBMSCs osteogenic ability was weakened significantly, miR-21 expression decreased, and Spry1 expression increased, indicating an inhibition to the miR-21-Spry1 function axis. Through the transfection of miR-21 and down-regulation of Spry1, the expression levels of Runx2 and Osterix were increased, and PMOP-hBMSCs osteogenic ability was partially restored.

Objective To study the drug resistance situation of Mycobacterium tuberculosis strains isolated from the patients with HIV/AIDS complicating tuberculosis (TB).Methods One hundred and ninety-six inpatients with AIDS complicating TB in our hospital from January 2012 to December 2015 were collected.The drug resistance situation of Mycobacterium tuberculosis strains cultured from sputum/tissue fluid/fiber liquid and pathological tissue submitted samples in the patients with AIDS complicating active TB was analyzed.The BACTEC MGIT960 systems was adopted to perform the bacterial identification.The drug sensitivity test was conducted by using 960 culture testing system.Results One hundred and ninety-six strains of Mycobacterium tuberculosis were cultured,the total drug resistance rate of Mycobacterium tuberculosis was 26.02％.These cases were divided into the ＞100/μL and ≤100/μL groups according to different CD4+ T cells count.The drug resistance situation of Mycobacterium tuberculosis to 4 kinds of first line anti-TB drugs were compared between these two groups.The comparison results found that the resistance rate of Mycobacterium tuberculosis strains to the first line anti-TB drugs had no statistical difference between the two groups (P＞0.05).The resistance rates of first line anti-TB drugs from high to low were isoniazid,rifampicin,streptomycin and ethambutol.The drug resistance rate of Mycobacterium tuberculosis strains to 5 types of drug resistant TB had no statistical difference(P＞0.05).Conclusion The drug resistance rate in the initial patients with HIV complicating TB is consistent with the average initial drugresistance level of TB patients in our country.The TB drug resistance rate in the patients with HIV complicating TB has no correlation with CD4+ T cells count.

Objective To investigate the detection of human bocavirus (HBoV) in children with acute respiratory infection and to explore the relationship between viral load and clinical characteristics of acute respiratory infection in children.Methods A total of 4 501 nasopharyngeal secretion samples were collected from hospitalized children with acute respiratory infection from January 2013 to June 2013.HBoV-positive children were divided into simple infection group and mixed infection group.Children with HBoV DNA≥1 × 104 copy/mL were categorized into high viral load group,while those with HBoV DNA ＜1 × 104 copy/mL were categorized into low viral load group.HBoV was determined by fluorescence quantitative polymerase chain reaction (PCR).Respiratory syncytial virus (RSV),influenza virus (Inf)-A,Inf-B,parainfluenza virus (Pinf)-Ⅰ 、Pinf-Ⅱ 、Pinf-Ⅲ and adeno virus antigen were detected by direct antigen-specific immunofluorescence assays.Mycoplasm Pnuemonia was detected by real-time fluorescence quantitative PCR.Serum mycoplasma antibodies were detected by enzyme-linked immunosorbent assay (ELISA).Bacteria was detected by sputum culture.Over the same period,23 children undergoing elective inguinal hernia operation with no respiratory infection or fever were considered as control group.The percentage of peripheral blood T lymphocyte subsets were tested by flow cytometry.Inter-group differences were compared using Chi-square test or Fisher exact test.Viral loads were compared using Mann-Whitney test.Results Two hundred and twenty-two HBoV-positive cases were detected with a positive rate of 5.41％ (222/4 105),33.33％ (74/222) of which were with high viral load and 66.67％ (148/222) were with low viral load.There was a high incidence in the age group of 1-2 years.The simple HBoV infection accounted for 24.32％,including 26 cases with high viral load and 28 cases with low viral load.Wheezing was more common in patients with high viral load than those with low viral load,and the difference was statistically significant (88.46 ％ vs 42.86 ％,x2 =12.295,P=0.001).Among the 222 HBoV-positive cases,the median viral load of HBoV in simple infection group was 3.86 × 103 copy/mL,and 1.0× 103 copy/mL in mixed infection group.The difference of the viral load between these two groups was statistically significant (Z =2.906,P =0.004).Mycoplasma and Streptococcus pneumonia were most commonly detected in the 168 patients with mixed infection.Percentages of CD3+ and CD3+/CD8+ subsets were significantly lower in HBoV simple infection group and mixed infection group,compared to control group (both P＜0.05).However,percentages of CD3 /CD19+,CD19+/ CD23+ subsets were significantly higher in HBoV simple infection group and mixed infection group,compared to control group (both P＜0.05).Conclusions HBoV is one of the pathogens causing acute respiratory tract infection in children,which lead to cellular immunity dysfunction in children.Moreover,children with higher HBoV load are more likely to develop wheezing.Co-infection with other pathogens should be considered in children with low HBoV load.

BACKGROUND:Previous studies have found that miR-21 expression is increased during osteogenic differentiation of bone marrow mesenchymal stem cells, but the action and molecular mechanism of miR-21 are stil unclear. OBJECTIVE:To verify the target gene of miR-21, Spry1, and to explore the role of Spry1 in osteogenic differentiation of human bone marrow mesenchymal stem cells. METHODS:Luciferase report was used to verify Spry1 gene targeted by miR-21, and western blot assay was used to detect the expression of Spry1 in the osteogenesis of human bone marrow mesenchymal stem cells. Spry1 expression vector was established and transfected into human bone marrow mesenchymal stem cells. Osteogenesis ability of human bone marrow mesenchymal stem cells was analyzed after Spry1 high expression by alkaline phosphatase, alizarin red staining, RT-PCR and western blot. RESULTS AND CONCLUSION:Luciferase report suggested that Spry1 was a target gene of miR-21. The expression level of Spry1 was decreased in the osteogenesis of human bone marrow mesenchymal stem cells. Increasing expression of Spry1 could inhibit osteogenic differentiation of human bone marrow mesenchymal stem cells. These results indicate that Spry1 as a target gene of miR-21 negatively regulates osteogenic differentiation of human bone marrow mesenchymal stem cells, and plays an important role in bone formation process.
