Objective To investigate the relation of the expressions of matrix metalloproteinase-2(MMP-2)and-9(MMP-9)with polymyositis/dermatomyositis(PM/DM).Methods Blood samples were obtained from 8 patients with PM,12 patients with DM and 10 normal human controls.Real-time quantitative RT-PCR and Western-blot were applied to examine the mRNA and protein expressions of MMP-2 and MMP-9 respectively in the peripheral blood mononuclear cells(PBMC)of these patients.Results The mRNA expression levels of MMP-2 and MMP-9 in the PBMC of patients with PM or DM were 2.41 and 1.66 folds as high as those of the normal controls,respectively;these difierences were significant between the two groups.Increased expressions of MMP-2 and MMP-9 were also noted in the patients with PM or DM.Conclusion MMP-2 and MMP-9 may play a part in the development of polymyositis and dermatomyositis.

Objective To investigate the efficacy of precise hemihepatectomy guided by middle hepatic vein(MHV),and to study the value of preoperative hepatic vein evaluation.Methods The clinical data of 68 patients who received hemihepatectomy at the Nanjing Drum Tower Hospital from October 2007 to September 2009were prospectively studied.Of the 68 patients,30 received precise hemihepatectomy guided by MHV(precise group)and 38 received anatomical hemihepatectomy(traditional group).The types of hepatic vein in the precise group were evaluated and classified preoperatively.The operation time,operative blood loss,volume of blood transfusion,liver function,morbidity and length of hospital stay of the 2 groups were compared.All data were analyzed using the t test,rank sum test,chi-square test and Fisher exact probability.Results According to the Nakamura's classification,there were 17(57%)patients with type Ⅰ,8(27%)with type Ⅱ and 5(16%)with type Ⅲ;according to the Kawasaki's classification,there were 11 patients with type Ⅰ(37%)and 19 with type Ⅱ(63%).There were 13 patients received right hepatectomy with MHV preservation,15 received left hepatectomy with MHV preservation,1 received right hepatectomy without MHV preservation and 1 received left hepatectomy without MHV preservation.There were no significant difference in the volume of operative blood loss and blood transfusion,level of alanine transaminase,total bilirubin,cholinesterase at postoperative day 3,total length of hospital stay and length of postoperative hospital stay between the 2 groups(t = 1.07,0.92,0.07,0.21,0.63,0.63,0.75,P ＞ 0.05).The operation time,levels of albumin at postoperative day 3 and complication rate were (342 ± 113)minutes,(35 ±3)g/L and 40%(12/30)in the precise group,and(270 ±73)minutes,(33 ±3)g/Land 66%(25/38)in the traditional group,respectively,with significant differences between the 2 groups(t =2.79,2.19;x2 =4.49,P＜0.05).The positive rates of the resection margin were 5%(1/19)in the precise group and 35%(8/23)in the traditional group,there was a significant difference between the 2 groups(P ＜0.05).ConclusionPreoperative hepatic vein evaluation and precise hemihepateetomy guided by MHV can preserve the functional liver tissues with venous drainage,achieve adequate tumor-free resection margin and reduce the postoperative complication rate.

Objective To summarize the clinical characteristics , diagnosis and surgical method of intra-ductal papilloma(IP)of breast without nipple discharge .Methods The clinical data of 84 IP patients(130 le-sions)without nipple discharge admitted from Feb .2011 to Oct.2013 were analyzed retrospectively .Results The age of the 84 patients were mainly ranging from 30 to 50 years old.113(86.92%)lesions were≤10 mm in size, 84(64.42%)lesions had a distance≤20 mm to nipple, 57 accompanied by adenosis , 43 accompanied by fibro-cystic adenosis , 48 accompanied by fibroadenoma , 14 with ductal hyperplasia , and 2 with atypical ductal hyper-plasia.After a follow-up of 3 to 36 months, 5 cases had recurrence , including 4 cases of IP and 1 case of ductal carcinoma in situ.Conclusions IP without nipple discharge has no typical clinical symptoms .Ultrasound exam-ination may have positive findings , but not typical .Preoperative diagnosis is difficult and surgical biopsy is rec-ommended.Multiple and atypical ductal hyperplasia has possibility of recurrence , so follow-up is necessary.

Objective To evaluate the effect of propofol on liver injury in mice with acute liver failure (ALF).Methods Eighty adult male ICR mice,aged 1 months,weighing 20-25 g,were randomly divided into 3 groups (n =20 each) using a random number table:control group (group Ⅰ),ALF group (group Ⅱ),and ALF + propofol group (group Ⅲ).ALF model was established with intra-peritoneal D-galactosamine (D-GaIN) and lipopolysaccharide (LPS).Propofol 5 mg/kg was injected via the tail vein every 1 h within 6 h after injection of DGaIN and LPS in group Ⅲ,while the equal volume of normal saline was given instead in the other groups.Venous blood samples were taken from the tail vein at 1,3 and 6 h after injection of D-GaIN and LPS (T1-3) to detect the activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) and serum tumor necrosis factor-alpha (TNF-α),interleukin-1β (IL-1β) and IL-10 concentrations (by ILISA).The survival within 12 h after injection of D-GaIN and LPS was observed and the survival rates were calculated.The mice were sacrificed and livers were removed for microscopic examination of pathologic changes.Results Compared with group Ⅰ,the activities of AST and ALT were significantly increased at each time point in Ⅱ and Ⅲ groups and the serum TNF-α concentrations at T1,2 and IL-1β and IL-10 concentrations at each time point were significantly increased in group Ⅱ,and the serum TNF-α concentrations at T1,and IL-1β and IL-10 concentrations at T2,3 were significantly increased in group Ⅲ (P ＜ 0.05).Compared with group Ⅱ,the activities of AST and ALT at each time point,serum TNF-α concentrations at T1,2 and IL-1β and IL-10 concentrations at T2,3 were significantly decreased and the survival rate within 12 h after injection of D-GaIN and LPS was increased in group Ⅲll (P ＜ 0.05).The pathologic changes of liver tissues were gradually attenuated in Ⅱ and Ⅲ groups.Conclusion Propofol can reduce the liver injury in mice with ALF through inhibiting inflammatory responses.

Objective:To explore the expression of Ezrin and CD44v6 in gastric carcinoma and their correlations to clinicopathologic features. Methods:The expression of Ezrin and CD44v6 were detected by immunohistochemistry in gastric carcinoma(n=53) and normal gastric mucosa(n=20).Results:①The positive expression rates of Ezrin in gastric carcinoma and normal gastric mucosa were 56.6% and 30.0%.While the positive expression rates of CD44v6 in gastric carcinoma was 58.5% and no expression in normal gastric mucosa.②The expression of Ezrin was correlated to the differentiation(P0.05).③The expression of Ezrin was positively correlated with that of CD44v6 in gastric carcinoma(rs=0.740,P

Infantile diarrhea was divided into four types of wind cold,damp heat,food injury and spleen deficiency on differentiation of symptoms and signs.The techniques of tonifying the spleen,clearing Dachang(large intestine),rubbing the abdomen and pressing Zhixie (stopping diarrhea) point,Zusanli (ST 36) and Changqiang (GV 1) as well as pinching the spine were chosen to treat this disease with a satisfactory result.

Objective To investigate the alteration of NKT cells number in patients with systemic lupus erythematosus (SLE) and its correlation with SLE disease activity.Methods Blood samples were obtained from 30 patients with SLE and 30 healthy control subiects.The number of NKT cells from peripherial blood mononuclear cells (PBMC) were detect by flow cytometry (FCM).Two independent samples t-test and Pearson correlation was used to evaluated the relationship between SLE disease activity and NKT cells.Results Compared with healthy controls [(4.16±0.22)%],lower number of NKT cells were found in SLE group[(2.53±0.33)%](P<0.05).An inverse correlation was observed between the frequency of NKT cells and IgG,anti-dsDNA,SLE disease activity index.Conclusion Reduced proportions of NKT cells observed in patients with SLE and is associated with high SLE disease activity.
