Background:As the incidence of acute pancreatitis( AP)is increasing and the mortality remains high,early identification and early intervention of patients at risk of severe acute pancreatitis(SAP)is of great clinical significance. Aims:To investigate the value of commonly used AP-related serum biochemical markers for early prediction of severity of AP. Methods:Retrospective analysis was performed in 205 AP patients in Renmin Hospital of Wuhan University from Jan. 2014 to Dec. 2014,and 92 healthy subjects were served as controls. Patients with AP were divided into mild(n = 92), moderately severe(n = 72)and severe AP(n = 41)groups. The demographic characteristics,history of chronic diseases, serum biochemical markers within 48 hours after admission,Ranson score,BISAP score and other related clinical data were collected and compared between the four groups. The diagnostic performance of these indices in predicting SAP was evaluated by ROC curve,and the correlation of these indices with SAP was assessed by Logistic regression analysis. Results:There were significant differences in Ranson score,BISAP score,D-dimer,blood calcium,procalcitonin(PCT), CRP,hypersensitive CRP(HS-CRP),triacylglycerol and blood glucose between the four groups(P < 0. 05). The area under curve(AUC)of blood calcium was 0. 838 for early prediction of SAP,which was second to that of Ranson score and BISAP score. The accuracies of PCT and D-dimer were acceptable but inferior to blood calcium,while the accuracies of other indices were considerably low. Logistic regression analysis revealed that the odds ratio of risk for SAP of Ranson score,PCT and HS-CRP were all greater than 1 000,while that of blood calcium and D-dimer were 0. 013 and 19. 479, respectively. Conclusions:Of the AP-related serum biochemical markers,blood calcium,D-dimer and PCT are the preferred early predictors for severity of AP.

Background:Acute kidney injury(AKI)is one of the early serious complications of acute pancreatitis(AP). Early identification and intervention have important clinical significance. Aims:To investigate the early predictive value of clinical indicators found within 48 hours after admission for AKI in patients with AP. Methods:A retrospective analysis of 205 AP patients from January 2014 to December 2014 at Renmin Hospital of Wuhan University was performed. AP patients were divided into AKI group and non-AKI group according to the KDIGO standard,the demographic characteristics,history of chronic diseases and indicators defined within 48 hours after admission such as Ranson score,BISAP score and biochemical indices were compared. The early predictive value of clinical indicators for AKI was evaluted,and strength of association between clinical indicators and AKI was assessed. Results:Compared with non-AKI group,Ranson score, BISAP score,D-dimer,PCT,blood glucose,triacylglycerol were significantly increased in AKI group(P < 0. 05),and calcium was significantly decreased(P < 0. 05). The accuracies of D-dimer,PCT,calcium were high for early prediction of AKI,and the AUC were 0. 881,0. 803 and 0. 782,respectively. Logistic regression analysis showed that D-dimer, PCT,calcium had marked correlation with AKI(OR all > 7)(P < 0. 05). Conclusions:D-dimer,PCT and calcium are effective and economical clinical indicators for the early prediction of AKI in patients with AP.

Osteoarthritis is mainly caused by the degenerative changes of cartilage and cartilage extracellular matrix,while Aggrecanases degradate Proteoglycans which are the major components of cartilage.This review includes three aspects:(1) We have concluded the major enzymes(ADAMTS-4 and ADAMTS-5) which regulate the metabolism of cartilage extracellular matrix.Meanwhile,we have summarized the structure of aggrecanases(ADAMTS-4 and ADAMTS-5) and introduced the function of each regional structure;(2) We have concluded the way cytokines and glycosaminoglycans regulate the metabolism of aggrecanases,and discussed the regulation and control principle of cytokines and glycosaminoglycan;(3) We have summarized the majority of inhibitors to the aggrecanases,introduced the endogenic inhibitors,and put our emphasis on the extrinsic inhibitors(chelating agents,polypeptides and so on).Through deeper research on the enzymes,it will help us further understand the pathogenesis of osteoarthritis,and open up new avenues to clinical treatment.Abstract:SUMM ARY Osteoarthritis is mainly caused by the degenerative changes of cartilage and cartilage extra-cellular matrix,while Aggrecanases degradate Proteoglycanswhich are the major components of cartilage.This review includes three aspects:(1) W e have concluded the major enzymes(ADAMTS-4 and ADAMTS-5) which regulate the metabolism of cartilage extracellular matrix.Meanwhile,we have sum-marized the structure of aggrecanases(ADAMTS-4 and ADAMTS-5) and introduced the function of each regional structure;(2) W e have concluded the way cytokines and glycosam inoglycans regulate the metab-olism of aggrecanases,and d iscussed the regulation and control principle of cytokines and glycosam inogly-can;(3) W e have summarized the majority of inhibitors to the aggrecanases,introduced the endogenic inhibitors,and put our emphasis on the extrinsic inhibitors(chelating agents,polypeptides and so on).Through deeper research on the enzymes,it will help us further understand the pathogenesis of osteoar-thritis,and open up new avenues to clinical treatment.

Objective To determine whether LTB4 could indirectly stimulate human osteoclast differentiation in RA through increasing RANKL expression of RAFLs. Methods We utilize the coculture model of RAFLs and monocyte which were stimulated in the presence of 2.5 ng/ml M-CSF in the control group, 2.5 ng/ml M-CSF +10-8 mol/L LTB4 in the experimental group A, 2.5 ng/ml M-CSF+10-8 mol/L LTB4+100 ng/ml OPG in the experimental group B. After culture for 3 weeks, through TRAP staining we counted the number of multinucleated TRAP staining positive osteoclast-like cells stained with TRAP to evaluate the differentiation effect in each group. Results There was almost no osteoclast-like cell in the control group and the experimental group B. Whereas there were many osteoclast-like cells in the experimental group A. Conclusion LTB4 can indirectly stimulate human osteoclast differentiation in RA through increasing RANKL expression of RAFLs.

Objective To study the changes of neutrophil surface molecule CD64 and inflammatory factor levels in patients with burn infection. Methods 46 cases of patients with burn infection who were treated in the department of burn in our hospital between March 2010 and October 2015 were selected as the observation group. Meanwhile, 46 cases of healthy people who underwent physical examination in our hospital during the same period were included in the control group. The levels of neutrophil surface molecule CD64, C-reactive protein (CRP), white blood cell count (WBC) and inflammatory factor [interleukin IL-6 (IL-6), interleukin (IL-8), tumor necro-sis factor (TNF-α) in the two groups of subjects were determined by flow cytometry and were compared. Results In the observation group, the levels of CD64, CRP, WBC and inflammatory factors were significantly higher than those in the control group (P < 0.05). Conclusion The levels of CD64, CRP, WBC and inflammatory factors in patients with burn infection are significantly higher than those in healthy people , which indicates that neutrophil surface molecule CD64, inflammatory factors and burn infection are closely correlated.

Yolk sac tumor (YST) is a rare germ cell neoplasm of childhood that usually arises from the testis or ovary. The rare cases of YST in various extragonadal locations have been reported, but the primary intrarenal YST is even more uncommon. Here, we report a case of a primary intrarenal YST with tumor thrombus of the inferior vena cava and left renal vein in a 2-year-old boy, with an emphasis on the CT features. To our knowledge, this is the first reported case of an intrarenal YST with intravascular involvement.

Objective Toinvestigatetheriskfactorsforleukoaraiosis(LA)inpatientswithlarge arteryatherosclerosis(LAA).Methods Theclinicaldata(age,sex,hypertension,diabetes,smoking, serum lipid level,hyperhomocysteinemia,and numbers of stenosis or occluded cerebral arteries)of 312 patients with LAA classified by the modified stop stroke study trial of Org 10172 in acute stroke treatment (SSS-TOAST ) were analyzed retrospectively. The age-related white matter changes (age related white matter changes,ARWMC)scale was used to evaluate LA. All the 312 patients were divided into non-LA group(n=72)and LA group(n=240)according the T2 weighted magnetic resonance imaging (MRI) and fluid attenuated inversion recovery(FLAIR)sequence,and 3 groups according to the (age-related white matter changes,ARWMC)scores:mild LA,moderate LA,and severe LA groups. The patients with multiple risk factors were analyzed by the univariate and multivariate Logistic regression analyses. Results (1)Of the 312 patients with LA,227 were males (72. 8%). Their average age was 64 ± 11 years,and 240 of them (76. 9%)had LA. Multivariate Logistic regression analysis showed that age (OR,2. 911,95%CI 1. 647-5.146,P=0. 000),hypertension (OR,2. 583,95%CI 1. 373-4.857,P<0. 01),diabetes (OR,1. 882, 95%CI 1. 058-3. 348,P <0. 05),the numbers of stenosis or occlusion arteries (OR,1. 851,95%CI 1.018-3. 367,P<0. 05),and lacunar infarction (LI)(OR,1.493,95%CI 1. 202-1. 853,P<0. 01)were the risk factors for LA. (2)The comparison of the clinical data in patients with different severity in the LA group found that there were significant differences in age,hypertension,diabetes,the numbers of stenosis or occlusionarteries,andLIamongthe3groups(allP<0.05).Conclusion Age,hypertension,diabetes, the numbers of stenosis or occlusion arteries,and LI are the independent risk factors for patients with LAA,and it is associated with the severity of LA.

Objective: To understand the microbial contamination of student lunch in Huzhou, in order to provide reference for foodborne disease prevention and control. Methods: In 2021, 225 samples of student lunch were randomly collected from 77 schools and detected for E.coli, S.aureus, B.cereus, Salmonella, Campylobacter, Listeria monocytogenes, and Diarrhoeal E.coli. According to the relevant standards, the status of microbial contamination was evaluated. Results: The total unqualified rate was 2.67 %(6/225). The unqualified rates of E coli (>100 CFU/g) was 1.33%. The detection rates of B.cereus, S.aureus, Listeria monocytogenes, and diarrhoeal E.coli were 7.11%(16/225), 1.33%(3/225), 0.89%(2/225) and 0.44%(1/225), respectively. The unqualified rates of S.aureus (≥10 4 CFU/g) and B.cereus (≥10 5 CFU/g) were zero. There are statistical differences in the unqualified rate of student lunch among different school types( P <0.05). The unqualified samples mainly came from the primary school canteen, and the unqualified rate was 5.63%(4/71). Conclusion The sanitary quality of student lunch in Huzhou is acceptable, but there are different degrees of foodborne pathogens pollution, especially in primary schools, and supervision and management should be strengthened.

OBJECTIVETo explore the value of comprehensive application of CT and PET/CT in differential diagnosing mucinous and non-mucinous colorectal adenocarcinoma.

METHODSCT and PET/CT image data of 37 patients with mucinous adenocarcinoma and 50 patients with non-mucinous adenocarcinoma confirmed by pathology in our hospital from January 2010 to December 2012 were analyzed retrospectively. Differences of image were compared between two methods.

RESULTSOn CT, lesion density of pre-contrast, pro-contrast phase and enhancement degree were significantly lower in mucinous adenocarcinoma than those in non-mucinous adenocarcinoma(all P<0.01). Enhancement degree of hypointense area, hypointense area proportion of total lesion, and lymphatic or distant metastasis ratio were significantly higher in mucinous adenocarcinoma than those in non-mucinous adenocarcinoma(all P<0.05). On PET/CT, maximal SUV value of mucinous adenocarcinoma was significantly lower as compared to non-mucinous adenocarcinoma[(8.64±4.34) Bq/L vs. (12.38±5.96) Bq/L, P=0.015].

CONCLUSIONSCT combined with PET/CT provides better valuable information in differential diagnosing between mucinous and non-mucinous colorectal adenocarcinoma and clinical practice.

Objective:To compare the suicidality risk in major depressive disorder (MDD)patients with and without anxious characteristics,and analyze the risk factors of suicidality in MDD patients. Methods:This was a secondary analysis of the data from the Diagnostic Assessment Service for people with Bipolar Disorders in China (DASP),which was initiated by the Chinese Society of Psychiatry (CSP),from September 1,2010 to February 28, 201 1. Based on the anxious module and suicide module of Mini International Neuropsychiatric Interview (M. I. N. I),1 172 MDD patients were classified as suffering from anxious MDD (n=728,62. 1%)and non-anxious MDD(n=444,37. 9%). Logistic regression was employed to examine the risk factors of suicidality in MDD pa-tients. Results:Among the anxious MDD patients,331 (45. 5%)of them had suicidality risk. And 54(12. 2%)of non-anxious MDD patients had suicidality risk. Compare to the non-anxious group,the anxious MDD patients had significantly higher suicidality risk (P<0. 00 1 ). Logistic regression analysis showed that more frequent depressive episodes (OR=2. 07 ),depressive episodes with psychotic symptoms (OR=2. 0 1 ),comorbid with anxious charac-teristics (OR=3. 18)or melancholic characteristics (OR=2. 90)were associated with suicidality risk in patients with MDD. Conclusion:It indicates that the anxious MDD patients may have higher suicidality risk than non-anx-ious MDD patients,and more frequent depressive episodes,depressive episodes with psychotic symptoms,comorbid with anxious characteristics or melancholic characteristics may be risk factors of suicidality in patients with MDD.
