Objective:To investigate the causes of false-positive anti-HCV in non-syndromic cleft lip and palate with serum chemiluminescence test. Methods:We performed a hospital-based,case-control study of 4 050 patients with non-syndromic cleft lip and palate and 8 547 control patients without cleft lip and palate to evaluate associations between positive anti-HCV and non-syndromic cleft lip and palate. CLIA test were used for detect anti-HCV in control group. RIBA and FQ-PCR were used for confirming the result of the positive samples of CLIA test. CLIA test were used for detect anti-HCV in case group until CLIA test was negative. IgG,RF and ANA were used for case-control comparisons. Results:The detection rate of anti-HCV were higher in the case group than that of control group (P<0. 05). The false-positive rate was 1 percent based on testing of 4 050 patients. These samples were negative after opration 1-19 months. There were no change among IgG, RF and ANA in the false-positivepatients. Conclusion: False-positive anti-HCV in non-syndromic cleft lip was possible associated with abnormal plasma metabolic product. It can be excluded by track monitoring.

Objective:To investigate the diagnostic and terapeutical value of FPG,GA,HbA1c and GA/HbA1c ratio in T1DM/T2DM.Methods:The study was made by case-control method.In our study,30 healthy subjects were selected from health physical ex-amination as control group while 160 diabetics were selected as case group,in which there are 76 TIDM and 84 T2DM.Analyzing the difference of relevance of FPG,GA and HbA1c,the difference of GA/HbA1c and threshold of the case and the control,and this analysis was also used between the T1DM and the T2DM.The data was managed by independent-sample t test,ROCK and Pearson correlation test of SPSS.Results:The results of FPG,GA ,HbA1c and GA/HbA1c ratio of T1DM and T2DM were significantly higher than those in the control group(P<0.01).And they were higher in the T1DM than in the T2DM(P<0.01);in the T1DM group,GA was strongly positive correlative with HbA1c(P<0.01),FPG was weakly positive correlative with GA(P>0.05),and weakly negative correlative with HbA1c(P>0.05);in T2DM group,there were positive correlation among FPG,GA and HbA1c(P<0.05),the degree of correlation ranked as HbA1c/GA>FPG/GA>FPG/HbA1c;analyzing the ROC of measures in T1DM group,the sensitivity and specificity were re-spectively 86.8% and 100% for diagnosing DM when FPG threshold was set on 5.86 mmol/L ( AUC=0.922 ) ( P<0.05 ).The sensitivity and specificity were both 100% for detecting DM when GA threshold was set on 15.5%( AUC=1 ) ( P<0.05 ).The sensitivity and specificity were respectively 98.7%and 100%for diagnosing DM when HbA1c threshold was set to 6.10%( AUC=1) ( P<0.05).The sensitivity and specificity were respectively 93.4% and 100% for diagnosing DM when the threshold of GA/HbA1c was set on 2.95 ( AUC=0.992 ) ( P<0.05 );analyzing the ROC of measures in T2DM group, the sensitivity and specificity were respectively 91.7% and 100% for diagnosing DM when FPG threshold was set on 5.94 mmol/L ( AUC=0.941 ) ( P<0.05 ).The sensitivity and specificity were respectively 85.7%and 100%for diagnosing DM when GA threshold was set on 15.5%( AUC=0.977) ( P<0.05).The sensitivity and specificity were respectively 97.6% and 100% for diagnosing DM when HbA1c threshold was set on 5.95%(AUC=0.991)(P<0.05).The ratio of GA/HbA1c had no diagnostic cutoff point,AUC was 0.644(P>0.05).Conclusion:FPG,GA, HbA1c and GA/HbA1c ratio are of high value in monitoring of blood glucose, diagnosis and typing in T1DM and T2DM.There are missed diagnosis when we diagnose T1DM and T2DM by the upper limit of reagent instruestion of FPG,GA,HbA1c.It is more important for a person with T1DM to monitor FPG than others.

Objective To investigate the genetic mutation of the norA gene and its promotor from the wild-type drug-resistance Staphylococeus aureus(S.aureus)strains. Methods A total of 10 antibiotic-resistant S.aureus strains were isolated and screened from the burn wound for the sequencing and analysis of the nora gene and its promoter. Results There isolated 87 S.aureus strains from the burn wound flora,which were completely sensitive to vacomycin,highly sensitive to Quinupristin and Nitrofurantoin,but highly resistant to the other antibiotics,even up to91.7% of MRSA.There found the same point mutation(G→A) located at 1 349 sites of the norA gene coding region in all the S.aureus strains,saying that the amino acid was changed from Gly(glycin)to Asp(agpartic acid) in 291 sites.The resetpine reverse test showed that the MICs value of three antibiotics was lowered at various degrees in all 10strains.Conclusion NorA gene mutation is one of the mechanisms for antibiotic-resistance of S.aureus.

Objective:The clinical features, risk factors, and outcomes of coma were analyzed in patients treated with bevacizum-ab combined with chemotherapy This study also aims to increase the awareness on the toxicity of this regimen. Methods:Two cases of coma induced by bevacizumab combined with chemotherapy were reported. Diagnosis, treatment, and relevant literature were reviewed and discussed. Results:Inadequate blood pressure (BP) control was one of the risk factors leading to coma in patients treated with this therapy. The clinical feature of these patients was reversible posterior leukoencephalopathy syndrome (RLPS). Imaging results showed no typical finding. Reinforced supportive treatment including intensive BP control showed satisfactory outcomes. Conclusion:Coma is common in patients treated with bevacizumab combined with chemotherapy. This regimen should be used cautiously in patients with a history of hypertension. BP should be monitored closely and managed promptly during the combination therapy to prevent coma. RLPS-related coma is reversible after appropriate treatment.

Objective: To study the propagation and phenotypes changes of killer cell (CD3AK cell activated by CD3 mAb in vitro. Methods: Lymph nodes taken from lung cancer patient is dissociated into single cell suspension by mechanical method and cultured in culture medium added CD3 mAb and a little dose IL-2. We analyze cell immunophenotype by flow cytometry and proliferation by trypan blue exclusion test per 2 days. Results: Immunophenotypic analysis showed that CD3AK expressing CD3, CD8, CD56, CD25 increased, and reached a peak value which is 2.33 times than before culturing in the 8 th day. Conclusion: CD3 mAb added to the culture medium can obviously activate CD3AK cell and stimulate proliferation and keep its killer activity.

Aim To study the effect of tetramethylpyrazine(TMP) on binding of 125I-VEGF to VEGF receptor. Methods The mice sera were collected after peritoneal injection with big-dose TMP,low-dose TMP,protamine and NS. A reversed-phase high performance liquid chromatography(RP-HPLC) method was used to determine the TMP in mice serum. The culture medium of ECV304 was treated with the mice sera in different groups. Radioligand binding assay(RBA) of receptor and Scatchard pot were performed to observe the changes of the maximum binding capacity(B_ max) and dissociation constant(K_d).Results The sera of big-dose TMP inhibited 125I-VEGF binding to its receptor, K_d=343.30?36.64 pmol?L-1,B_ max=46.26?5.85 fmol/2?10~5 cells(P0.05),but B_ max decreased(P

Abstract In order to achieve the goal of reducing the smoking rate among Chinese adults at ages of 15 years and above to below 20% by 2030, smoking cessation services require to be reinforced. The current Chinese smoking cessation service system includes short-term smoking cessation interventions and smoking cessation hotlines at the population level, and smoking cessation clinics at the individual level; however, these smoking cessation services suffer from problems of low awareness, low accessibility and low utilization rate. Based on the publications pertaining to smoking cessation services and released policy documents in China until June 2022, this review analyzes the current status, problems and causes of smoking cessation services, and proposes suggestions for improving the smoking cessation service system construction in China.

One hundred and thirteen newly-diagnosed type 2 diabetic patients were treated with rosiglitazone for 16 weeks. Glucose tolerance was restored in 46 cases ( group A), but not restored in 67 cases (group B). Compared with group B,the patients of group A were younger and had shorter course of diabetes and lower body mass index (BMI,P＜0.05); Homeostasis model assessment for β-cell function (HOMA-β) and earlyphase insulin secretion in group A were better than those of group B before and after treatment respectively (P＜0. 05 ) ,while homeostasis model assessment for insulin resistance ( HOMA-IR )in group A was lower than that of group B before treatment (P＜0. 05 ). In conclusions, rosiglitazone improved insulin resistance of type 2 diabetes patients, thus facilitated restoration of β-cells function and glucose tolerance. The related factors of glucose tolerance restoration included age ,diabetes duration, BMI, HbA1 c, β-cells function, and insulin resistance.

Temporomandibular joint disorder (TMD) is one of the common diseases in stomatology caused by a variety of factors, with a high incidence rate, especially among the young people with great pressure, and difficult to treat this disease. it was easy to relapse directly affects the physical and mental health and quality of life of the patients. Psychological factors had been proved to be one of the causes of temporomandibular joint disorder, and cognitive behavioral therapy was a form of psychological therapy that has been applied to a variety of problems, including mental illnesses such as depression, anxiety, and physical symptoms like pain. Cognitive behavioral therapy (CBT) was also used in stomatology department. This paper reviewed the origin, concept formation, theory formation, characteristics and application of CBT in TMJ disorders, in order to provide more evidence for clinical practice and reduce pain for patients.

Objective To survey the situation and related factors of maintenance medication treatment in schizophrenic patients re-hospitalized for relapse. Methods 362 patients re-admitted with schizophrenia and their relatives were interviewed with questionnaire which included 16 factors that might affect maintenance medication treatment. Results 63.8% patients stopped medication and 21.1% patients were on low-dose maintenance medication treatment by themselves, while 7.7% patients were on reasonable dose anti-psychotics in 2 years. The time of maintenance medication treatment related with insight (OR=2.2144, P=0.001), family care (OR=4.8842, P=0.025), outcomes of treatment (OR=2.2056, P=0.007) and negative life events (OR=0.4529, P=0.003). Conclusion Schizophrenic patients re-admitted with relapse often withdraw or reduce their medication by themselves, which risked with poor insight, poor therapeutic effect, poor care from their family, and more negative life events
