OBJECTIVEThe present study was designed to investigate the influence of viral myocarditis on mental behavior of the children.

METHODSMentality and behavior of the 178 children suffering from viral myocarditis were examined with Achenbach Child Behavior Checklist (CBCL) edited by Gong Yao-xian in 1986 and 104 sex, age, education and achievement-matched children with pneumonia or upper respiratory infection were enrolled as controls.

RESULTSThe mentality and behavior of the children with viral myocarditis were distinctly abnormal. The abnormal rates of boys and girls suffering from acute and deferment viral myocarditis were evidently higher than those of control children (P < 0.01). The behavioral abnormalities of boys were hypochondria, social difficulties, unwell of body and attack. Whereas, the girls presented hypochondria, unwell of body, social flinch and disobeyed discipline, which was significantly different from the control children. The total and hypochondria cursory mark of the second check result of deferment boys were evidently higher than those of the first check (P < 0.05). The total cursory mark of the second check result of deferment girls was higher than that of the first check (P < 0.05) and evidently higher than that of the acute second check result (P < 0.01). The abnormal rates of mentality and behavior correlated positively with the age of children and they were associated with the severity of the illness.

CONCLUSIONViral myocarditis evidently affected the mentality and behavior of children, which should be paid great attention to.

Objectives To investigate changes in serum levels of adiponectin,leptin and erythrocyte membrane insulin receptor among patients with gestational diabetes (GDM),and to study their relation to insulin resistance.Methods Fasting plasma glucose (FPG),fasting serum insulin (FINS), serum levels of adiponeetin and leptin,indices of lipid metabolism,2 h plasma glucose during oral glucose tolerance test (2 h PG),2 h serum insulin during oral glucose tolerance test (2 h INS),as well as number of erythrocyte membrane insulin receptors with high and low appetency and its constants,were determined in 40 patients with GDM and 34 controls with normal glucose tolerance.Insulin resistance index (IRI) was calculated.Results ① Serum levels of leptin and adiponectin were (11.7?2.8) ?g/L and (7.8?1.6) ?g/L,respectively,and number of high appeteney erythrocyte membrane insulin receptor (R_1) and low appetency erythrocytemembrane insulin receptor (R_2) was (43?9) / red cell and (2297?525) / red cell,respectively.Serum level of leptin was significantly higher in those with GDM than those of normal controls (P

OBJECTIVETo study the changes of serum interleukin-2 (IL-2), interleukin-8 (IL-8) and immunoglobulin (IgG, IgA, IgM) in patients with esophageal cancer, and to probe the relationship between the levels of IL-2, IL-8, IgG, IgA and IgM and the progress of cancer.

METHODSThe serum levels of IL-2 and IL-8 were detected by enzyme-linked immunosorbent assay for 72 case of primary esophageal cancer, 68 advanced esophageal cancer and 120 healthy controls, and the level of immunoglobulin (IgG, IgA, IgM) in patients with esophageal cancer was dynamically observed.

RESULTSThe IL-2 level in patients with early esophageal cancer [(1.69 +/- 0.53) ng/ml] or late esophageal cancer [(1.11 +/- 0.60) ng/ml] was lower than the control group [(2.78 +/- 0.51) ng/ml] (P < 0.01), the late esophageal cancer group was lower than early esophageal cancer group (P < 0.05). The level of IL-8 in patients with early esophageal cancer [(85.48 +/- 6.14) ng/L] or late esophageal cancer [(121.41 +/- 6.22) ng/L] was much higher than the control group [(54.48 +/- 12.20) ng/L] (P < 0.01), the late esophageal cancer group was much higher than early esophageal cancer group (P < 0.01); There was correlation between the levels of IL-2 and IL-8 and the worsen-extent of the tumour in patients with early esophageal cancer or late esophageal cancer. But the level of IgG [(12.23 +/- 2.50) g/L], IgM [(1.60 +/- 0.80) g/L] in the patients with esophageal cancer compared with the level of IgG [(11.65 +/- 3.70) g/L], IgM [(1.46 +/- 0.71) g/L] in the health control group have no significant difference (P > 0.05), the level of IgA [(3.50 +/- 1.10) g/L] in patients with esophageal cancer Compared with the control group [(1.88 +/- 1.08) g/L] has significant difference (P < 0.01), and along with the worsen-extent of the tumor in patients the level of IgA has the increased tendency.

CONCLUSIONThe IL-8 might accelerate the pathogenesis of esophageal cancer, and the IL-2 might restrain. The positive correlation between the level of IgA and the patients with esophageal cancer is observed in this study; the immune maladjustment of IL-2, IL-8 and IgA might be correlative to esophageal cancer, and the IL-2, IL-8 and IgA levels might be an available index for the severity of esophageal cancer, Which may be of some help for clinic practitioners to judge the progress, curative effect and prognosis of the cancer.

OBJECTIVETo investigate the impact of the extent of gastric resection on the prognosis of patients with middle one-third gastric cancer.

METHODSFrom January 1998 to December 2005, 222 patients with middle one-third gastric cancer underwent D2 radical resection in the Affiliated Union Hospital, Fujian Medical University. Among them, 66 underwent distal gastrectomy (DG group), while 156 underwent total gastrectomy (TG group). The 5-year survival rates were compared between two groups. The prognostic factors were evaluated by univariate and multivariate analyses.

RESULTSThe 5-year survival rates of DG group and TG group were 63.9% and 49.8% respectively, with significant difference (P<0.05). Nevertheless, compared to DG group, the tumors in TG group had bigger size, later TNM stage, and higher proportion of locating lesser curvature of stomach (all P<0.01). Multivariate analysis revealed that invasion depth, lymph node metastasis and TNM classification were independent prognostic factors (all P<0.05), but the extent of gastric resection was not (P>0.05).

CONCLUSIONIf curative resection can be performed, the long-term prognosis of patients with middle one-third gastric cancer is not affected by the extent of gastric resection, and distal gastrectomy is feasible.

OBJECTIVEGenetic evolution of VP1 of enterovirus type 71 in Shenzhen were analyzed.

METHODSAll samples were tested by RT-PCR using EV71 specific primer. The VP1 of EV71 were amplified and sequenced. A phylogenetic tree was constructed by comparison of the sequences with subgenotype A, B and C using DNAStar, BioEdit and Mega 3.1 software.

RESULTSAmong 35 strains, the homogeneity of the VP1 nucleotide sequence was between 92.1%-100%. The homogeneity of the VP1 nucleotide sequence with subgenotype A and B was between 81.4% -91.1%. The VP1 nucleotide sequence of 35 strains of Shenzhen shared between 93% -97.4% identity with cluster C4. The prevalence strains of EV71 were cluster C4b from 1998 to 2004, and gradually moved to C4a since 2003. All of EV71 were C4b from 2006 to 2008. Also, the homogeneity of the VP1 nucleotide sequence with Anhui FY23 EV71 strain were 94.5% -94.7%, 95.7% -95.8%, 96.2%, 95.4% -97.5%, 96.3% -99.2% from 2003 to 2008. It shows that the homogeneity was increased year by year. There was a mutation (A --> C) at No. 66 nucleotide of VP1 of EV71 that two strains were isolated in 2003 and 8 strains in 2008, that caused amino acid mutation (Q --> H) at No. 22 of VP1.

CONCLUSIONEV71 C4b was gradually moved to C4a from 1998 to 2008. There was a missense mutation at No. 66 nucleotide of VP1.

OBJECTIVETo analyze related factors which affect GPA mutation frequency of workers exposed to benzene, with the Glycophorin A (GPA) mutation assay and explore the possibility of GPA mutation frequency as an index of predicting the risk of benzene poisoning.

METHODSThe erythrocytes were bound with fluorescent-labeled monoclonal antibody after isolated and fixed from the peripheral blood, and then the GPA mutation assay was performed using the flow cytometry (FCM). The related factors of GPA mutation frequency were analyzed by statistical methods.

RESULTSThe GPA mutation frequency of chronic benzene poisonings was significantly higher than that of their controls (P < 0.05). Significant direct correlation was found between age, length of service, accumulative exposure score and the GPA mutation frequency of workers exposed to benzene (P < 0.01). However, there was significantly inverse correlation between the 3AB index and the GPA mutation frequency (GPAN0: r(s) = -0.589, P < 0.01, GPANN: r(s) = -0.615, P < 0.01). In the multiple factor regression analysis on GPA mutation frequency, benzene exposure and individual susceptibility both entered model of multiple factors analysis, the coefficient of determination of benzene-exposed workers was 0.819.

CONCLUSIONExposure to benzene and individual susceptibility are the most important factors that affect GPA mutation frequency. GPA mutation frequency increases with the benzene exposure and individual susceptibility.

OBJECTIVETo study the value and the clinical application of the Medical Image three-dimensional Visualization System of Abdomen (MI-3DVS) in diagnosis and evaluating resectability of pancreatic tumor.

METHODSTwelve patients with pancreatic tumor were tested with 64-slice helical CT (64-MSCT) angiography, and the CT data was reconstructed with MI-3DVS from November 2008 to August 2009. The 3D findings were adopted in diagnosis and evaluating resectability, and the results were compared with surgical operation and the pathological finding. There were 7 male and 5 female, aged from 14 to 83 years. Within the 12 cases, there were 4 cases with pancreatic carcinoma, 5 cases with pancreatic solid pseudopapillary tumor, 2 cases with pancreatic serous cystadenoma, 1 case with pancreatic cyst (ductal epithelial papillary hyperplasia).

RESULTSNine tumors which had been regarded as removable pre-operatively with MI-3DVS were removed successfully. Three patients who were considered unresectable by other hospitals with CT were operated successfully with MI-3DVS. The other 3 patients' tumors were actually not able to be removed as pre-operative evaluation.

CONCLUSIONMI-3DVS plays an important role in diagnosis and assessment of resectability of pancreatic tumor.
