Objective To investigate the clinic value of procalcitonin( PCT)and c-reactive protein ( CRP)in differential diagnosis for febrile diseases. Methods One hundred and forty patients with febrile diseases in May 2009 to February 2014 in the No. 309th Hospital of People Liberation Army were investigated and analyzed retrospectively. Based on discharge diagnosis,patients were divided into bacterial infection group( n=58),non-bacterial infection group(n=47)and rheumatic diseases group(n=35),another 40 healthy people were served as the control group. Serum PCT and CRP were detected and compared in four groups. One month after backing to normal temperature in all the patients,detected serum PCT and CRP again. Results Serum PCT and CRP level in bacterial infection group,non-bacterial infection group,rheumatic diseases group and control group were(5. 18 ± 1. 92)and(0. 45 ± 0. 22),(0. 34 ± 0. 13)and(0. 16 ± 0. 05)μg/L,(25. 31 ± 4. 24), (1. 94 ± 0. 37 ),( 62. 32 ± 15. 10 ) and( 1. 30 ± 0. 04 ) mg/L respectively. Serum PCT and CRP level in bacterial infection group were significantly higher than that in control group(P﹤0. 01). Even though serum PCT and CRP level in non-bacterial group slightly higher than that of healthy control group,there was no statistical difference(P﹥0. 05). Serum PCT and CRP level in bacterial infection group were significantly higher than that of non-bacterial infection group( P ﹤0. 01 ). Serum CRP level in rheumatic diseases group was significantly higher than that of healthy control group( P﹤0. 01),while PCT level only slightly higher compared with healthy control group(P﹥0. 05). One month after backing to normal temperature in all the patients,serum PCT and CRP level in bacterial infection group reduced significantly compared with that of febrile period( P ﹤0. 01). Serum PCT and CRP level in non-bacterial infection group were no significant change( P﹥0. 05 ),and serum CRP level in rheumatic diseases group reduced significantly( P﹤0. 01 ),while serum PCT were no significant change(P﹥0. 05). Conclusion Serum PCT combined with CRP might be of great importance in the differential diagnosis for febrile diseases.

OBJECTIVETo investigate EXT1 and EXT2 genes mutations in a family with hereditary multiple osteochondromas (HME).
METHODSA four-generation family with HME from Linyi city of Shandong Province was studied. There were 6 affected individuals among the 17 family members. Physical examination and radiographical evaluations were carried out for all family members. Genomic DNA was extracted from peripheral venous blood and the samples were subjected to mutation screening by PCR of the coding regions of EXT1 and EXT2 genes.
RESULTSThe family has featured an autosomal dominant inheritance pattern. Sequencing of the EXT1 and EXT2 genes suggested the causative gene in this family was in linkage with the second exon of EXT2. A c.244delG mutation was detected, which has resulted in a frameshift mutation p.Asp81IlefsX30. The mutation was found in all of the 6 affected individuals but not in normal family members. And the mutation has co-segregated with the phenotype.
CONCLUSIONThe mutation c.244delG in the EXT2 gene is the probably the cause of the disease in this family.

Objective To observe the relationship between CYP2C19 gene polymorphisms and major adverse cardiovascular events in the patients of acute coronary syndrome (ACS) who accepted percutaneous coronary intervention (PCI) in Han population from Dalian. Methods A total 809 cases with ACS who had undergone PCI in the cardiology department of Dalian Municipal Central Hospital from Janurary 2012 to Janurary 2014 were selected,Among 809 cases of ACS,there were 178 cases of acute ST segment elevation myocardial infarction (STEMI),105 cases of acute non ST segment elevation myocardial infarction (NSTEMI) and 526 cases of unstable angina. The patients were divided into three groups according to their CYP2C19 genotype.CYP2C19 genotype (*1/*1) were classified as extensive metabolizers (EM group), CYP2C19 genotype (*1/*2、*1/*3) were classified as intermediate metabolizers (IM group) and CYP2C19 genotype (*2/*2、*3/*3、*2/*3) were classified as poor metabolizers (PM group). The occurrence of major adverse cardiovascular events at least 24 months was observed. Results Seven hundred and ninety patients finished the follow-up at least 24 months, 19 patients lost in follow-up, 350 cases (43.2%) were CYP2C19 (*1/*1),318 cases (39.3%) were CYP2C19(*1/*2), 42 cases(5.2%) were CYP2C19 (*1/*3),77 cases (9.5%) were CYP2C19 (*2/*2), 21 case(2.2%)were CYP2C19 (*2/*3), and 1 case (0.1%) was CYP2C19(*3/*3), 350 cases (43.2%) were classified as EM group, 360 cases (44.5%) were classified as IM group, and 99 cases(12.2%)were classified as PM group. No significant difference in age, gender, hypertention, diabetes mellitus, smoking was shown among three groups (P > 0.05). The rate of MACE were 3.3% , 8 cases had target lesion revascularization(EM group 3 cases, IM group 3 cases, PM group 2 cases), 2 cases had non-fatal myocardial infarction (IM group 1 case, PM group 1 case), 15 cases were died(EM group 6 cases, IM group 7 cases, PM group 2 cases), 1 case had subacute stent thrombosis in IM group. The rates of MACE were higher in PM group (5.1%) than those in EM group(2.65%) and IM group (3.41%) , but there was no significant difference in three groups (P>0.05). There was no significant difference in the rate of target lesion revascularization , thrombus in stent, non- fatal myocardial infarction and death among three groups(P > 0.05). Conclusions There is no significant correlation between CYP2C19 gene polymorphism and long-term prognosis in patients with ACS who accepte PCI treatment in Han population from Dalian.

Objective:
To study the effect of nutrition intervention on the body composition and blood glucose in newly diagnosed patients with type 2 diabetes mellitus complicated with overweight and obesity.
Methods:
A total of 84 newly diagnosed patients with type 2 diabetes mellitus complicated with overweight and obesity were selected from the department of endocrinology in China-Japan Friendship Hospital from April 2015 to December 2016. Basic information and body composition of these patients were collected and measured. Also the food frequency questionnaire (FFQ) was used to investigate the dietary status in the past month, and calculate the intake of energy, three major nutrients and dietary fiber. All patients received nutrition intervention by nutritionist for three months as requested by Diabetes guidelines. After 3-month intervention, blood glucose, body composition and dietary status were examined again. Relevant indicators of patients were compared before and after the intervention. All patients were divided into three groups according to the degree of body mass index (BMI)′s change: <5%, 5%-10% and >10%. The differences of body weight, muscle, body fat rate, visceral fat index and blood glucose level among three groups were quantified.
Results:
There were 53 male patients with age (41.5±8.9) years and HbA1c (7.5±0.4)%, and 31 female patients with age (40.1±8.5) years with HbA1c (7.6±0.5)%. The intake of energy, carbohydrate and fat of patients were significantly decreased (

Objective To explore relationship between clinical features and peripheral blood test indicators and curative effect in adult patients with acquired hemophagocytic syndrome (HPS). Methods A total of 61 adult patients with acquired HPS who were admitted to the First Affiliated Hospital with Nanjing Medical University and the Affiliated Jiangning Hospital of Nanjing Medical University from April 2014 to March 2017 were enrolled, including 38 males and 23 females, with a median age of 48 years (17-86 years). The retrospective analyses of their clinical data and laboratory examination results were made in this study. Results There was no significant difference in the therapeutic effective rate of 61 HPS patients caused by different inducements after treatment (P =0.184). The prothrombin time (PT) before treatment was higher than that after treatment [(12.90±1.97) s vs. (12.35±1.78) s, P= 0.046]; the level of lactate dehydrogenase (LDH) before treatment was higher than that after treatment (median: 476 U/L vs. 231 U/L, P = 0.000); the level of D-dimer (D-D) before treatment was higher than that after treatment (median: 1.46 mg/L vs. 0.51 mg/L, P = 0.007); the level of aspartate aminotransferase (AST) before treatment was higher than that after treatment (median: 54.9 U/L vs. 26.0 U/L, P= 0.000); the level of serum calcium before treatment was lower than that after treatment [(2.07±0.20) mmol/L vs. (2.18±0.23) mmol/L, P = 0.043]. The peripheral blood platelet counts (Plt) in the effective group (32 cases) before treatment was higher than that in the ineffective group (29 cases) (median: 104.0×109/L vs. 63.5×109/L, P =0.007), the level of albumin (ALB) in the effective group was higher than that in the ineffective group [(35.50 ±6.17) mmol/L vs. (31.93 ±6.54) mmol/L, P = 0.033], the level of serum calcium in the effective group was higher than those in the ineffective group [(2.18±0.18) mmol/L vs. (2.08±0.20) mmol/L, P = 0.047], the level of prothrombin time (PT) in the effective group was lower than that in the ineffective group [(12.40±1.76) s vs. (13.43±2.06) s, P = 0.041], and the level of LDH in the effective group was lower than that in the ineffective group (median: 415.0 U/L vs. 593.5 U/L, P= 0.032). Conclusion The lower expressions of Plt, ALB and serum calcium, and the higher expressions of PT and LDH may indicate the poor prognosis of adult acquired HPS, and there fore these patients need to be paid attention.
