Objective To explore the value of the combined detection of helper T lymphocyte (Th)1 and 2 type cytokines ex‐pression in the evaluation of acute pancreatitis severity and treatment efficacy .Methods From May 2009 to June 2013 ,the enzyme‐linked immunosorbent assay (ELISA ) was adopted to detect the expression levels of Th1‐type cytokineinterferon‐γ (IFN‐γ) and Th2‐type cytokine interleukin (IL)‐4 in 32 cases of mild acute pancreatitis (MAP group) and 18 cases of severe acute pancreatitis (SAP group) on 1 ,4 ,7 d after admission as well as 15 cases of normal healthy people (control group) .Results The test results of IFN‐γ on 1 ,4 ,7 d after admission in the MAP group were (31 .47 ± 4 .35) ,(36 .92 ± 4 .12) ,(49 .09 ± 4 .97)ng/L ,which of IL‐4 were (54 .72 ± 5 .52) ,(45 .26 ± 4 .89) ,(39 .79 ± 3 .85)ng/L .The test results of IFN‐γ on 1 ,4 ,7 d after admission in the SAP group were (23 .97 ± 5 .39) ,(26 .29 ± 3 .47) ,(33 .64 ± 4 .47)ng/L ,and which of IL‐4 were (70 .45 ± 5 .05) ,(65 .99 ± 4 .58) ,(56 .23 ± 4 .23)ng/L .The test results of IFN‐γ and IL‐4 in the normal control group were (49 .26 ± 20 .67)ng/L and (35 .15 ± 16 .32)ng /L respectively .Compared with the normal control group ,the expressions of Th1‐type cytokine IFN‐γ in the MAP group (except which on 7 d) and peripheral blood Th1‐type cytokine IFN‐γ in the SAP group were decreased and the expression of Th2‐type cyto‐kine IL‐4 was increased ,the difference was statistically significant (P< 0 .05) ;The test results of each index in the same treatment time had statistically significant differences between the SAP group and the MAP group (P< 0 .05) .Conclusion The obvious po‐larization of Th1‐type cytokine and Th2‐type cytokine exists in acute pancreatitis ,and the polarization degree is related with the se‐verity of disease .The combined detection of Th1‐type cytokine and Th2‐type cytokine is beneficial to judge the extent of serious condition and treatment effect of acute pancreatitis .

Objective To assess the leading causes of death and disability adjusted life year (DALY) due to non-communicable disease (NCD) in China.Methods World Health Report 2004 published by the World Health Organization (WHO) was reviewed,including total deaths,deaths per 100 000,agestandardized death rate per 100 000,total DALYs,DALYs per 100 000 and age-standardized DALYs per 100 000 by cause and by member state.Diseases or injuries were assigned to three levels:communicable diseases,NCD and injuries (the first level); categories of disease or injure (the second level); specific diseases (the third level).R2.15 was used for data analysis.Results NCD causes 737.6 million deaths,141million total DALY years,627 age standardized mortality per 100 000,and 10 829 age-standardized DALYs per 100 000.NCD account for 79.4％ and 70.3％ total death or all-cause DALYs.Conclusions Cardiovascular disease,malignant neoplasm and respiratory disease were the leading causes of death,while neuropsychiatric disorder,cardiovascular disease and sense organ disease were the most important causes of DALYs.Among China,the United Kingdom,the United States,Canada,Japan,Korea and India,China ranked second in age-standardized mortality rate of chronic disease.DALYs of esophagus cancer and chronic obstructive pulmonary disease were 6 or 2 times of world average level.Besides,the increasing trend in the prevalence of diabetes mellitus remains impressive.

Objective To compare the changes in TLR4-NF-κB signaling pathway in infant and adult mice infected with influenza virus, and to provide experimental evidence for the study of immunopathological mechanism in pediatric respiratory virus susceptibility. Methods Immunohistochemistry and RT-PCR were applied to detect the expressions of lung TLR4 and NF-κB P65 mRNA and proteins in the infant and adult mice, and to compare the changes in TLR4-NF-κB P65 signaling pathway after infection with influenza virus.Results (1) The infant model group showed the strongest expression of TLR4 protein in the lung tissue, compared with that in the normal group and adult model group showing significant differences (P<0.05).(2) The expression of NF-κB P65 protein in the lung tissue was strongest in the infant model group, and it was gradually increased over time, showing a significant difference between each time point and the next time point (P<0.05).(3) The infant model group showed the strongest expression of TLR4 mRNA in lung tissue, significantly higher than that in the normal and adult model groups (P<0.05).(4) The expression of NF-κB P65 mRNA in the lung tissue was highest in the infant model group, and significantly higher than that in the normal and the adult model groups ( P<0.05) , and it was gradually increased with the time.Conclusions The over-activation of TLR4-NF-κB P65 signaling pathway may be one of the immunopathological mechanisms of serious injury in the lung tissue in infant rats.

To explore an effective method with few operative complications for treating circumferential mixed hemorrhoids (CMH).Sixty three cases of CMH (Group A) were treated with limited external incision and internal ligation combined with restoration of intervenient skin and 34 cases (Group B) were treated with traditional external incision and internal ligation as control. Anal canal diameter (ACD), anal canal quiescent pressure (ACQP) and anal canal systolic pressure (ACSP) were determined before and after operation. Short term and long term therapeutic effects were also observed and compared in the two groups.Short term and long term therapeutic effects in Group A were better than those in Group B (P

Objective:To investigate the risk factors of rotator cuff tears combined with long head of bicep tendon (LHBT) lesion and its effects on preoperative function.Methods:From January 2016 to January 2020, there were 680 patients with rotator cuff tears, including 260 males and 420 females, were included. The average age was 56.1±8.7 (range 27-74 years). There were 250 cases on the left side and 430 cases on the right side. There were 436 cases on the main side, while 274 cases had definite trauma before operation. The following were the Post rotator cuff tears classification, 133 cases in partial injury, 473 cases in small and medium size of rotator cuff tears, 74 cases in large and massive size of rotator cuff tears. The Habermayer-Walch classification of LHBT lesions was as following, 302 cases in type 0 (normal), 216 cases in type 1 (tendonitis), 29 cases in type 2 (dislocation and subluxation), 104 cases in type 3 (partial tear), 20 cases in type 4 (complete tear) and 9 cases in type 5 (SLAP injury above type II). The patient with rotator cuff tears were divided into partial tears group, medium and small tears group, large and massive tears group according to the classification of Post. The visual analogue scale (VAS), simple shoulder test (SST), Constant-Murley function score and the score of the University of California Los Angeles (UCLA) were recorded. The differences in age, sex, main side, trauma and LHBT lesion in patients with three types of rotator cuff tears were analyzed. The preoperative pain and function scores of patients with or without LHBT lesions in various rotator cuff tears were compared among the groups by t-test. The age, sex, main side, with trauma or not, and the classification of rotator cuff tears were analyzed by Logistic regression to investigate the risk factors of patients with rotator cuff tears with LHBT lesions. Results:There were 378 cases (55.6%) with LHBT lesions in 680 patients with rotator cuff tears, including 216 cases of tendinitis (57.1%), 104 cases of partial tear (27.5%), 29 cases of dislocation and subluxation (7.7%), 20 cases of complete tear (5.3%) and 9 cases of SLAP injury (2.4%). The incidence of partial injury, small and medium injury, large and massive rotator cuff injury combined with LHBT lesions were 35.3% (47/133), 57.5% (272/473) and 79.7% (59/74) respectively. The preoperative VAS score, UCLA score, Constant-Murley score and SST score were 5.20±1.52, 14.81±4.12, 41.45±4.93 and 4.56±1.96 respectively in rotator cuff tears group and 5.29±1.65, 14.34±4.01, 41.60±5.88, 4.47±1.97 in LHBT group ( P>0.05). In the partial rotator cuff tears group, the VAS score was 5.16±1.41 in patients with simple rotator cuff tears and 5.68±1.46 in patients with LHBT lesion ( t=2.004, P=0.047). Regression analysis showed that age ≥60 years and rotator cuff tears degree were the risk factors for rotator cuff tears with LHBT ( P<0.001). Conclusion:It is common for patients to have rotator cuff tears with LHBT lesions. The more severe the rotator cuff tears are, the higher the incidence of LHBT lesions will be. Patients with rotator cuff tears aged 60 and above are more likely to have LHBT lesions. However, the complications of LHBT could not affect the preoperative pain and functional scores of patients with rotator cuff tears.

Objective To explore feasibility of the Chinese version of MoCA for the detection of vascular cognitive impairment-no dementia (VaCIND) and control in a cross-sectional study. Methods One hundred and three Chinese Han were assessed by the MoCA and MMSE. 64 met criteria for VaCIND and 39 were considered cognitively normal. Sensitivities and specificities were calculated using the recommended cut-off scores,and ROC curve analyses were performed to determine optimal sensitivity and specificity. Results No differences were found between groups on age,gender,education degrees. According to their MoCA scores,cognitive impairments including memory,visuospatial, executive function, attention, language, and orientation sub-scores in VaCIND ((0.44 ± 0.96), (2.13 ±1.40), (1.90 ±1.02), (4.61 ±1.41), (4.23 ±1.40), (5.38 ±1.15)) significantly decreased compared with that in controls((2.92 ± 1.42) ,(3.16 ± 1.08) ,(3.32 ± 1.07) ,(5. 87 ±0.41) ,(5.34 ±0.75), (5.79 ±0. 70)) (P<0. 05). The MMSE scale was insensitive to cognitive impairment as compared with MoCA scale. Using cut-off score of 24,the MoCA exhibited excellent sensitivity (0.923) and specificity (0.906). Conclusion MoCA is a more sensitive instrument than the MMSE for the detection of VaCIND and warrants further investigation regarding its applicability in large group and varying ethnic groups.

ObjectiveTo examine whether the single nucleotide polymorphisms in inflammation-related genes are associated with the risk of amnestic mild cognitive impairment (aMCI).MethodsThe study recruited 116 aMCI patients and 93 matched healthy controls.All subjects underwent extensive assessment of cognitive function,genotyping was carried out on the platform of matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry.Results ( 1 ) There was prominent discrepancy between aMCI and controls in the memory,attention and executive functions,20 minutes delayed recall of auditory verbal memory test (AVMT) (3.0(0.0 ～ 10.0 ),8.0 (0.0 ～ 12.0),t =- 8.533,P ＜ 0.05 ),recall of Rey-Osterrieth complex figure test ( R-O CFT) (11.2 ±8.3,16.1 ±8.0,t=4.216,P＜0.05),digit span test (DST) (12.0(7.0 ～ 19.0),13.0(7.0 ～20.0),Z=-2.516,P＜0.05),trail making test A (TMTA) (80.0s(35.0 ～200.0)s,72.0s(29.0 ～512.0)s,Z=-3.113,P＜0.05),trail making test B (TMTB) ((180.1 ±72.7)s,(141,7 ±52.1)s,t=-4.385,P＜0.05 ).(2) No significant differences were found in frequencies of alleles,genotypes and hapolotypes of inflammation mediator genes ( interleukin 10,interleukin 1 A,interleukin 1 B,tumor necrosis factor,interleukin 6,α1- an-tichymotrypsin gene,transforming growth factor B1 ) between aMCI and controls (P ＞ 0.05 ).ConclusionThe results indicate that polymorphisms in the inflammation-related candidate genes do not appear to be involved in the risk of developing aMCI.

Objective To investigate the relationship between amnestic mild cognitive impairment and functional genes associated with hyperphosphorylated tau protein.Methods One hundred and sixteen amnestic mild cognitive impairment (aMCI) patients and 93 normal controls were recruited for the study.Multi-dimension neuropsychologic tests were used to assess the cognitive function extensively.MassARRAY and iPlex systems were used to measure candidate SNP polymorphisms,analyze genotypic,allelic or haplotypic distributions and their interaction with ApoE ε4 and the correlation with the cognitive function in the subjects.Results ( 1 ) The scores of neuropsychologic tests in memory domain ( Auditory Verbal Learning Test (AVLT)-first immediate recall,AVLT-second immediate recall,AVLT-second immediate recall,AVLT-5 minute delayed recall,AVLT-20 minute delayed recall,AVLT-recognition,Rey-Osterrich Comolex Test-delay) in aMCI patients ( 3.0 ( 0-7.0 ),5.0 ( 1.0-10.0),6.0 ( 1.0-11.0 ),4.0 (0-11.0),3.0(0-10.0),20.0(8.0-24.0),11.2 ±8.3) were significantly lower than those in the normal controls(4.0(0-9.0),7.0(2.0-11.0),9.0(3.0-12.0),8.0(0-12.0),8.0(0-12.0),22.0 (10.0-24.0),16.1±8.0) (Z=-3.592,-6.802,-6.408,-8.173,-8.533,-5.647 andt=4.216 respectively,all P ＜0.01 ) ; (2) Genotypic distributions of rs242562 GG in aMCI (7.826％ ) were significantly lower than those in normal controls (20.65％,OR =0.3525,95％ CI 0.1411-0.8807,P =0.024 98),however there were no differences in the genotypic,allelic or haplotypic distributions between aMCI patients and controls of glycogen synthase kinase-3β,cyclin dependent protein kinase-5,calcium and calmodulin-dependent protein kinase-Ⅱ,cell division cycle 2,dual-specificity tyrosine-phosphorylation regulated kinase 1A and low density lipoprotein receptor-related protein 6; (3) MAPT/STH rs242562 genotype was correlated with AVLT-immediate recall,AVLT-delayed recall,Rey-Osterrieth Complex Test,Rey-Osterrieth Complex Test-delayed recall and Clock Drawing Test (H =9.763,12.258,10.508,9.624,10.767,F =3.700,3.123 and H =6.591 respectively,all P ＜ 0.05 ) ; (4) There were no differences in the distributions of MAPT/STH rs242562 GG genotype and ApoE ε4 haplotype between aMCI patients and normal controls.Conclusions MAPT/STH rs242562 GG genotype decreases the genetic risk of aMCI,which might have important role in memory function in aMCI.The interaction between rs242562 GG and ApoE ε4 doesn' t affect the susceptibility to aMCI.

ObjectiveTo investigate and evaluate the result and the possibility of the clinical application of autologous chondrocyte implant (ACI).MethodsFrom November 2007 to June 2009,6 cases of knee articular cartilage defect were treated with ACI,including 2 males and 4 females with an average age of 39.5 years (range,19-55).All the defects were located on the condyles of femur with a mean size of 7.3 cm2 (range,3.8-11.6).ACI comprises a two-stage procedure:chondrocytes are first harvested from the non-load bearing area of the joint,expand in vitro to acquire enough cells,and then the chondrocytes are implanted.The defect of cartilage were covered with bone membrane and fixed with sutures and fibrin albumen glue.Lysholm score system,International Knee Documentation Committee (IKDC) grading system,and MRI were used to evaluate the effect of ACI,6 and 12 months post-operatively.ResultsAll the patients were followed up.The clinical outcomes of the 6 and 12 months follow-ups demonstrated increased of clinical scores.The MRI follow-up showed good filling of the defect with tissue having the imaging appearance of cartilage in all patients.Only one patient suffered adhesion,because she refused to finish rehabilitation exercises as our treatment advises.ConclusionAs the clinical effect of ACI for knee cartilage defect is satisfied,the ACI may be a good choice for treating knee cartilage defect in future.It is very important to control the indications strictly and guarantee to finish the post-operative rehabilitation exercises.
