This study was to evaluate the effect of individualized health education on blood glucose control in type 2 diabetic(T2D)Patients.Two hundred and thirty-eight T2D patients were randomly received individualized diabetes education(intervention group)or general education(control group).At 48 week,change of blood glucose control from baseline was observed.The blood glucose level and HbA1c in the intervention group were lower than those in the control group[(7.1±0.8)vs (9.3±6.5)mmol/L,(7.0 ±1.3)%vs(8.0%±1.0)%;P＜0.05].Thus,individualized diabetes education might be helpful for blood glucose control in T2D patients.

OBJECTIVETo analyze the genotype-phenotype correlations in the Hb Constant Spring (HbCS) carriers, and to investigate the effect of HbCS on hematologic parameters.

METHODSComplete blood cell count and hemoglobin electrophoresis analyses were performed in 125 HbCS cases. The α-and β-thalassemia mutations were determined by reverse dot-blotting and Gap-PCR.

RESULTSThe presence of the SEA deletion or Hb Quong Sze (HbQS) with HbCS leads to HbH-CS disease. There was significant difference between HbH-CS and αCSα/-α, HbH-CS and αCSα/αα in the hematological parameters. The genotype of αCSα/-α or αα/αCSα had slight effect on hematological parameters. When the Hb Constant Spring mutation co-existed with heterozygous β-thalassemia, the hematological characteristics of β-thalassemia was presented. Only 57.6% of carriers with HbCS were detected by hemoglobin electrophoresis.

CONCLUSIONThe cases with co-existence of HbCS trait and other α-thalassemia trait, or β-thalassemia trait, showed variation in their red blood cell parameters. For such compound heterozygotes for HbCS and other α- or β-thalassaemia mutations, which were usually misdiagnosed in clinical screening by hemoglobin electrophoresis, accurate diagnose can be made by molecular diagnosis.

OBJECTIVETo study the clinical characteristics of urticaria in children versus adults, and to provide reference for the etiological analysis, disease evaluation, and treatment of urticaria in children.

METHODSThe clinical data of 2 411 patients with urticaria who visited the Department of Dermatology at Xiangya Hospital of Central South University from January 2013 to May 2017 were collected to study their socio-demographic characteristics. The clinical characteristics of urticaria were compared between the 68 children and 672 adults of the 740 patients with complete follow-up data.

RESULTSAmong the 411 pediatric patients, 314 (76.4%) had acute urticaria; among the 2 000 adult patients, 896 (44.8%) had chronic spontaneous urticaria. The causes of acute urticaria in children included infection (41%, 16/39). The accompanying symptoms of acute urticaria in children mainly included abdominal pain and diarrhea (44%, 17/39), while those in adults mainly included chest distress and shortness of breath (32%, 11/34). Compared with the adult patients, the pediatric patients had significantly lower chronic urticaria activity scores before and after treatment (P<0.05), a significantly higher rate of response to second-generation antihistamines (82.1% vs 62.2%; P<0.05), and a significantly higher proportion of individuals with a personal and family history of urticaria (P<0.05).

CONCLUSIONSAcute urticaria is more commonly seen than chronic urticaria in children with urticaria, and the main accompanying symptoms are abdominal pain and diarrhea, which are different from adults with urticaria. Chronic urticaria has a better treatment outcome in children than in adults. The most frequently seen cause of acute urticaria is infection in children. Atopic children may be susceptible to urticaria.

Objective To investigate the cognition impairment in depression patients with its event-related potential P300 and MR diffusion tensor imaging (DTI) and explore the mechanism of depression combined with cognition impairment Methods We conducted a study of 60 people: 30 patients with depression and 30 healthy controls group-matched by age, educational level andsocioeconomic status. The latency period and amplitude of P3, and the data of fractional anisotropy (FA) were measured by P300 examination and DTI, respectively, in the bilateral white matter of interested region. Correlation analysis of these 3 factors was performed in the 2 groups. At the same time, the scores of Wisconsin card sorting test (WCST) were detected. Results The WCST scores of each sub-item,and the P3 latency and amplitude between the control group and depression group had statistically significant differences (P<0.05). FA value in the white matter of the both frontal lobe, the anterior cingulate gyms, the supramarginal gyrus, splenium of the corpus callosum in the patients was significantly lower than that in the controls (P<0.05). P3 latency and percentage of persistent errors in depression patients were positively correlated (r= 0.677, P=0.009). P3 amplitude and both percentage of persistent errors and percentage of not being able to maintain a complete classification were negatively correlated, respectively (r=0.765,P=0.001; r=-0.654, P=0.012). FA values and both percentage of persistent errors and percentage of not being able to maintain a complete classification were negatively correlated in patients with depression in the bilateral frontal white matter, respectively (left: r=-0.544,P=0.003; r=0.489, P=0.023; right: r=0.665, P=0.002; r=0.448,P=0.027). Conclusions Neuropsychology and event-related potential P300 reflected the cognition impairment in patients with depression; the latency period and amplitude of P3 could be a reference index of evaluating the cognitive function. The outcome of DTI can reveal the possible abnormality of neurofibra in the white matter region, which may be one of its neuropathology in depression patients with cognition impairment.

Objective In this study,we attempted to investigate whether Electroacupuncture(EA)could promote the autophagy function in macrophages of inflammatory skin tissues by activating CB2 receptor,thus relieving inflammatory pain induced by CFA in mice,and whether activation of CB2 receptor in NR8383 macrophages cell line can simulate the effect of EA on the autophagy function and mitochondrial damage.Methods Inflammatory pain model was induced by CFA injection into the planta the hind paw of wildtype and CB2 knockout mice.EA or sham EA was applied on the left Huantiao(GB30)and Yanglingquan(GB34)sites.Thermal hyperalgesia was determined with the Hargreaves test.Mechanical sensitivity was assessed with von Frey filaments.NR8383 microphage cell line was used to study the effect of CB2 activation on macrophage function induced by CFA.The expression level of autophagy protein LC3 and p62 in wildtype and CB2 knockout mice skin tissue and NR8383 cell line were determined by Western blot.And flow cytometry analysis was applied to detect damaged mitochondria and mitochondrial superoxide.Results CFA significantly reduced the thermal and mechanical pain threshold in both wildtype and CB2 knockout mice,comparing with the vehicle control groups(P<0.01).EA significantly inhibited thermal and mechanical hyperpathia induced by CFA in wildtype mice(P<0.05),but had no effect on CB2 knockout mice with CFA(P>0.05).CFA significantly increased the expression of p62 protein and decreased LC3-II/I ratio,which was inversed by EA in wildtype mice but wasn't affected by EA in CB2 knockout mice.CFA increased the expression of p62 protein and decreased LC3-II/I ratio in NR8383 cell line,which were inversed by CB2 agonist AM1241.CFA increased mitochondria damage,which were then attenuated by CB2 agonist AM1241.Conclusion The analgesic effect of EA on inflammatory pain induced by CFA was mediated by activation of CB2 receptor,which promoted the autophagy function and the clearance of damaged mitochondria in macrophage.

OBJECTIVETo study the expression of HBsAg and HBcAg in hepatocytes in CHB patients, and analyze the correlation among the expression of HBsAg and HBcAg, the quantity of HBV DNA in serum, the pathology of liver tissue and the clinical manifestation.

METHODSQuantitative polymerase chain reaction was used to assay the quantity of HBV DNA in serum in 351 CHB patients. Furthermore pathological diagnosis was performed using liver biopsy to assay the expression of HBsAg and HBcAg in hepatocytes by an immunohistochemical staining technique.

RESULTSThe positive expression rate of HBsAg and HBcAg in hepatocytes was 92.3% and 76.9% respectively. Cytoplasm-membrane HBcAg expression type (75.6%) was observed in the CHB with more active inflammation, while Nucleus HBcAg expression type (24.4%) was observed in the CHB with more sedative one (P < 0.0001). The expression of HBsAg was correlated with the quantity of HBV DNA in serum (rp = 0.24, P = 0.0129), while inversely correlated with the inflammation and the fibrillation of liver tissue (rp = -0.22, P = 0.0279; rp = -0.23, P = 0.0186). The expression of HBcAg was correlated with the quantity of HBV DNA in serum (rp = 0.52, P < 0.0001), while was inversely correlated with the inflammation and the fibrosis of liver (rp = -0.33, P < 0.0001; rp = -0.34, P < 0.0001).

CONCLUSIONCytoplasm-membrane HBcAg expression type was observed in the CHB with more active inflammation, while Nucleus HBcAg expression type was observed in the CHB with mild change. In the immunopathogenesis of the liver damage in CHB, HBcAg might be a main target antigen. HBsAg might be a sensitive index to screen HBV infection; HBcAg might probably be a reliable index to evaluate the replication of HBV

OBJECTIVETo study the predictive effects of some health status indicators to deaths in the elderly population.

METHODSIn 1992, a cohort of 3257 people older than 55 years old was formed from Beijing urban and suburb area. Demographic and information of activity of daily living (ADL), self-rated health (SRH), chronic diseases history and other related variables were collected at baseline survey in 1992. MMSE and CES-D were studied in 2101 on 3257 elderly people. Follow-up surveys were conducted in 1994, 1997 and 2000, to find that a total number of or= 75), resident place (suburb) and education level (illiteracy). The functional disability, poor self-rated health status, history of chronic diseases and abnormal cognition function were the major predictors of deaths. Multinomial logistic regression analysis showed that after adjustment for sex, age, residential place, education level and history of chronic diseases, functional disability, poor self-rated health status and abnormal cognition function remained as significant independent predictors to death.

CONCLUSIONSFunctional disability, poor self-rated health status and abnormal cognition function were the most valuable indicators of death. Not only they had joined predictive effects to death, but also remained relatively independent. They had important value in the evaluation on healthy prognosis and the life quality of the elderly.

The effect of glycogen synthase kinase 3beta (GSK3beta) has been repeatedly implicated in cell proliferation, but studies on the effect of GSK3beta in different cell lines with different stimuli have drawn different conclusions. To investigate the direct effect of GSK3beta on cell growth in human lung adenocarcinoma cell line A549, we changed its activity by transient transfection with two kinds of GSK3beta mutant plasmids, constitutively active form S9A-GSK3beta and dominant negative form KM-GSK3beta. Twenty-four hours later, cell counting, flow cytometry and Western blot detection were made respectively. The results showed that enhancing GSK3beta activity caused a decrease in cell number, as well as a higher percentage of cells at G(1) phase. Further, the expression of cyclin D1 was down-regulated by GSK3beta. Taken together, our observations suggest that GSK3beta may induce G(1) cell cycle arrest in a cyclin D1-dependent fashion and therefore possibly plays a growth-inhibitory role in A549 cells.

OBJECTIVETo investigate the differentially expressed proteins among chronic sinusitis, nasal polyps and normal nasal mucosa by means of proteomic technology, and select the candidate biomarkers of chronic sinusitis and nasal polyps.

METHODSProteins extracted from chronic sinusitis, nasal polyps and normal nasal mucosa were separated and the differentially expressed proteins were identified by series of proteomic tools, including immobilized pH4-7 gradient two-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis, modified coomassie brilliant blue staining, images scanning by the Image Scanner apparatus, PDQuest analysis software, peptide mass fingerprinting based on matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS) by in-gel digestion extract, and Mascot searching in NCBInr and SWISS-PROT databases.

RESULTSThe 2-DE patterns with high resolution and reproducibility were obtained. The protein spots separated and visualized in chronic sinusitis, nasal polyps and normal nasal mucosa gel were 1020 +/- 40, 1112 +/- 10 and 1008 +/- 25, respectively. And the match rates were (93 +/- 2)%, (95 +/- 1)% [see text] (90 +/- 3)% respectively. Thirteen differentially expressed spots were found from chronic sinusitis, nasal polyps and normal nasal mucosa gel. We selected and recommend Keratin 8 and APOA1 proteins as candidate biomarkers of nasal polyps, and PLUNC protein, PACAP protein, NKEF-B and SOD as candidate biomarkers of chronic sinusitis.

CONCLUSIONSThe differentially expressed proteins among chronic sinusitis, nasal polyps and normal nasal mucosa can be efficiently and relatively reliably identified via the techniques of proteomics. These techniques will play a very important role in the researches for new objective indicators possibly employed in the future classifying, staging and prognosis.
