A dietary survey was conducted with the 3-day dietary intake record in 167 type 2 diabetic patients in Nandan Community of Xujiahui Subdistric of Shanghai, the results were transferred to healthy eating index (HEI). The average score of HEI was 74. 0. According to the criteria of HEI, diet quality of 7. 8% patients was "bad", that of 10. 8% patients was "good" and that of 81.4% patients was "need improvement". In all components, the fruits consumption was the worst, especially for male patients.Patients with higher educational levels had better dietary quality and patients who were on working had better HEI score than who retired. The obese and overweight patients consume more grains, meat and total fat than those with normal body weight.

Objective To investigate the effect of different concentrations of methotrexate (MTX) on IL-17 from peripheral blood mononuclear cells(PBMCs) and To clarify the active mechanisms of MTX on RA. Methods PBMCs were isolated from heparinized blood of healthy donors or patients with RA using Ficoll-Hypaque density gradient centrifugation. The cells were pretreated with various concentrations of MTX and then stimulated by anti-human CD3/anti-human CD28 at 37℃5%CO2. The IL-17 mRAN level was detected by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). The supernatants were harvested and the protein level of IL-17 was tested by ELISA kit. The percentage of CD4+IL-17+cells in PBMCs was detected by flow cytometry. Results For the four different concentrations of MTX groups (0.1,1.0, 5, 25μg/ml), the IL-17 mRNA/GAPDH ratio(0.58±0.09,0.48±0.11, 0.50±0.09, 0.51±0.14) were lower than those of the non-drug group(0.76±0.08). Paired-t test or independent-samplet test showed significant difference between the MTX treatment group and the non-drug group(P＜0.01). The level of IL-17 of the four MTX groups was(121±54)pg/ml and(104±45)pg/ml and(90±36)pg/ml and(115±41)pg/ml, which was lower than the non-drug group(370±187)pg/ml(P＜0.01). The average C D4+IL-17+cell ratio was reduced, but had no statistically signficant differences(P＞0.05). Conclusion MTX can decrease Th17 cells differentiation and suppress IL-17 production of PBMCs, but no association can be found between its effect on the expression of IL-17 and the concentration of MTX.

Objective To elucidate clinical significance of the varied concentration of cytokines in patients , the concentration of endothelin-1(ET-1) in cerebrospinal fluid(CSF) and serum were investigated in 36 patients with acute craniocerebral injury .Methods In this study ,36 patients with acute craniocerebral injury were divided into two groups by their GCS scores ( GCS≤12 as moderate-severe injury group ,GCS>12 as mild injury group ) .Concentration of ET-1 in CSF and serum in 36 patients with acute craniocerebral injury were detected by ELISA .Results The con-centration of ET-1 was(38.89 ±9.50)μg/L in cerebrospinal fluid ( CSF) in moderate to severe patients ,which were significantly higher than that in mild injury groups [(22.25 ±8.55)μg/L](t=5.453,P=0.000) and control groups [(15.67 ±7.72)μg/L](t=8.347,P=0.000).And the levels of ET-1 in CSF in the mild injury groups were also obviously higher than that of the control groups (t=2.390,P=0.023).On the other hand,the concentration of ET-1 was(107.02 ±17.25)μg/L in sera in moderate to severe patients ,which were also significantly higher than that in mild injury groups[(46.21 ±11.19)μg/L](t=12.176,P=0.000)and control groups[(32.34 ±10.64)μg/L] (t=16.163,P=0.000).And the levels of ET-1 in sera in the mild injury groups were obviously higher than that of the control groups(t=3.751,P=0.001).The concentration of ET-1 in sera was significantly higher than that of CSF (t=9.974,P=0.000).Conclusion The concentration of ET-1 in CSF and sera in patients with acute craniocere-bral injury were associated with severe of brain injury .

Objective:To investigate the classification of patients with gout, and further analyze their clinical features.Methods:Outpatients with gout were enrolled from January 2018 to July 2019 in Depart-ment of Rheumatology, Zhongshan Hospital. Subjects were classified into four groups according to their 24-hour urinaryexcretion and fractional excretion of urate. Clinical features of different groups were analyzed using one-way Analysis of Variance (ANOVA), Kruskal-Wallis H test, or χ2 test. Results:Finally, 378 subjects were enrolled in this cross-sectional study. Among them, 186(49.2%) were renal underexcretion type, 100(26.5%) were combined type, 57(15.1%) were renal overload type, 35(9.3%) were the normal type. Renal underexcretion type was the main subtype in any age-stratified groups. With aging, the proportion of combined type decreased, while the normal type increased. Participants in the combined type were the youngest [(42±14) years of age] with the highest estimated glomerular filtration rate [(94±18) ml·min -1·1.73 m -2], while their serum urate levels were the highest [(554±104) μmol/L]. Subjects in the normal type were the oldest [(60±15) years of age] with the lowest estimated glomerular filtration rate [(71±19) mL·min -1·1.73 m -2], however, their serum urate concentrations were the lowest [(427±118) μmol/L], The difference was statistically significant (age, F=13.98; estimated glomerular filtration rate, F=16.11; urate, F=17.14; P<0.01). Prevalence of urolithiasis were similar among the four groups ( χ2 =2.00, P>0.05). Conclusion:The renal underexcretion type is the main type of gout. Young patients are more likely to suffer from combined type with the highest serum urate levels and the best renal function.

Objective The aim of the present study is to measure multi-directional strain in patients with hyperuricemia through 3-dimensional speckle-tracking echocardiography (3D-STE) in order to investigate the left ventricular function early changes and clinical application value of 3D-STE. Methods 3-dimension dynamic images of left ventricular full volume in Apical 4-chamber heart view was collected and stored. 3-dimensional specke-tracking technology was applied to measure and compare the left ventricular multi-directional strain of patients with hyperuricemia and healthy controls in order to evaluate the left ventricular systolic function. Results A total of 24 healthy controls and 38 patients with hyperuricemia were included into the study. Among them,patients with hyperuricemia were divided into simple hyperuricemia group(n=12), hyperuricemia complicated with hyperlipidemia group (n=16)and hyperuricemia complicated with both hyper-tension and hyperlipidemia group (n=10). The circumferential strain [(-18.8±4.4)% vs (-25.9±6.4)%, t=-3.48, P=0.001] and area strain [(-31.2±3.9)% vs (-36.8±7.1)%, t=-2.55, P=0.018] of patients with simple hyper-uricemia significantly decreased compared with healthy controls. Besides, the circumferential strain [(-19.9 ± 5.8)% vs (-25.9 ±6.4)%, t=-3.02, P=0.002], longitudinal strain [(-12.6 ±3.3)% vs (-14.4 ±2.5)%, t=-1.95, P=0.038] and area strain [(-29.9±6.6)% vs (-25.9±6.4)%, t=-3.15, P=0.001] of patients with hyperuricemia complicated with hyperlipidemia significantly decreased compared with healthy controls. Conclusion Myo-cardial strain of patients with hyperuricemia complicated with hyperlipidemia or not is both decreased, indicating a decline in left ventricular systolic function.

Objective:To summarize the characteristics and treatment outcomes of immunoglobulin G4-related disease (IgG4-RD) overlapped with anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV).Methods:The clinical data of four patients with AAV overlaped with IgG4-RD from Zhongshan Hospital of Fudan University from August 2018 to July 2019 were collected and the related literature were reviewed.Results:Four patients were included, in which two were diagnosed with IgG-RD and granulomatosis with polyangiitis (GPA), one was probable IgG4-RD and microscopic polyangiitis (MPA), and one was probable IgG4-RD and GPA. All patients were female, with an average age of (42±12) (26-56) years, and disease duration was (7±4) (4-13) months. The manifestations were ocular inflammatory pseudotumor, sinusitis, otitis media, mastoiditis, parotitis, meningitis, lung and kidney involvement. After treatment with glucocorticoid and immunosuppressants (including cyclophosphamide, methotrexate, azathioprine, leflunomide), 2 patients failed to achieve remission, and 2 patients relapsed 8-15 months after treatment. One patient was treated withglucocorticoid pulse therapy combined with rituximab and one was treated with glucocorticoid combined with methotrexate and rituximab, and the patient was relieved.Conclusion:AAV and IgG4-RD may be a new overlap syndrome. Hypertrophic meningitis, orbital mass, chronic periaortic inflammation and interstitial glomerulonephritis are reported in the literature. The pathological changes of orbit, nasopharynx, parotid gland and lung are common. Glucocorticoids and immunosuppressive agents have poor treatment response, which indicates that AAV is refractory when combined with elevated IgG4. The induced remission rate is low, and easy to relapse. Glucocorticoid pulse therapy and rituximab treatment are effective.

Objective To observe the morphological changes of carotid artery wall by ultrasonography in patients with Takayasu arteritis,and to evaluate the diagnostic value of contrast-enhanced ultrasonography for active Takayasu arteritis.Methods High-frequency ultrasound technique was used to analyze the morphological changes of the carotid artery in 40 patients.NIH score was used as the gold standard and the complete clinical data and acute phase reactors were recorded.T test,Chi-square test,sensitivity and specificity were calculated for statistical analysis.Results The thickness of carotid artery wall in active group was much more thickened than the non-active group [(2.2±0.6) mm vs (1.8±0.5) mm,t=-2.142,P＜0.05].The CDD [(0.89±0.06) in active group vs (0.95±0.03) in non-active group,t=3.683,P＜0.01] and RDD [(0.17±0.06 in active group vs (0.09±0.05) in non-active group,t=-4.020,P＜0.01] were significantly different between the two groups.The distribution of neovascularization in the carotid artery wall of the active group was more diffuse in the central part of the wall.The sensitivity and specificity of contrast-enhanced ultrasonography to diagnose the active of Takayasu arteritis were 72.7％ and 87.5％ respectively,and the positive predictive value and the negative predictive value were 80.0％ and 82.4％ respectively.Conclusion Contrast-enhanced ultrasonography can be used as an effective way to assess the disease activity of TA patients.

Objective To explore the morphological characteristics of overlapping bloodstains and judge the deposition sequence of bloodstain patterns.Methods The overlapping bloodstains formed by drip stains and bloody shoe prints were simulated on ceramic tiles,and the morphological characteristic differences of 6 group overlapping bloodstain patterns were analyzed to screen effective indicative characteristics.A survey was held to measure the accuracy of the participants in judging the blood deposition sequence without and with information about the morphological characteristic guidance.Results After participants mastered morphological characteristics,the accuracy of judging deposition sequence increased from 59.5%to 89.0%,and the accuracy of judging dry and wet conditions of the primary bloodstains increased from 45.6%to 65.3%.Conclusion According to the morphological characteristics of bloodstains,not only the deposition sequence of bloodstains can be effectively judged,but also the dry and wet conditions of bloodstains can be judged,so as to infer the time interval of bloodstains deposition,which can provide technical support for the analysis and reconstruction of crime scene.
