Objective To investigate the changes of serum cytokines IL-2,IL-8,IL-10 and IFN-? in infants with cytomegalovirus hepatitis before and after ganciclovir treatment,and explore the underlying mechanisms of ganciclovir and the immunological changes in the development and progression of cytomegalovirus(CMV) infection.Methods CMV-IgM in the serum samples of 72 infants with identified cytomegalovirus infection were measured by enzyme-linked immunosorbent assay(ELISA).CMV DNA in blood was measured by quantitative PCR.CMV-IgM(+) and CMV DNA(+) were as observed group 1(35 cases,without hepatitis).Those with abnormality of ALT were regarded as observed group 2(37 cases,with hepatitis).Another 30 matched healthy infants were enrolled as healthy control group.Levels of serum IL-2,IL-10,IL-8 and IFN-? of each group were examined by ELISA,and CMV masculine hepatitis group were cured with ganciclovir(5mg/kg,i.v.,twice per day for 14 d,and then once per day for 14 d after a 7 days'interval),then the levels of above factors were examined again.Results The levels of IL-8 and IL-10 in observed group 1 were significantly higher than those in healthy control group(t=3.74,9.56;P0.05).After ganciclovir treatment,the level of IL-2 in observed group 2 was significantly higher than that in observed group 1(t=3.41,P0.05).The levels of IL-8,IL-10 and IFN-? were decreased significantly(t=6.52,7.24,14.23;P

OBJECTIVE To study the existence of integron and metallo-?-lactamase in Stenotrophomonas maltophilia in our hospital.METHODS The antibiotic susceptibility was tested by K-B method.The genomic DNA and their plasmids were extracted.The integron and metallo-?-lactamase gene were amplified by polymerase chain reaction(PCR).RESULTS L1 and L2 genes were amplified in chromosomes and plasmids.Integrons Ⅰ and Ⅱ were detected in genomic DNA.CONCLUSIONS Existence of metallo-?-lactamase is one of reasons of multi-drug resistance in S.maltophilia.S.maltophilia can receive integrons and gain its multi-drug resistance from other strains.

Objective To investigate the changes of serum cytokines and explore their role in infants with cytomegalovirus (CMV) infection. Methods We recruited 41 positive CMV-IgM plus normal ALT infants (other disease group), 30 positive CMV-IgM plus abnormal ALT infants (hepatitis group) and 30 healthy infants (control group) in the study. The levels of tumor necrosis factor-?(TNF-?), interferon-?(IFN-?) and interleukin-4 (IL-4) in serum were measured with ELISA. The association between TNF-? and ALT was analyzed. Results The levels of TNF-?, IFN-?, IL-4 were higher, and IFN-?/IL-4 was significantly lower in the two CMV infection groups than the control group. Compared with other disease group, the changes of TNF-?, IL-4, and IFN-?/IL-4 showed significance in hepatitis group. The level of TNF-? showed a positive association with ALT in hepatitis group(r=0.76,P

OBJECTIVE:To optimize the matrix formula of Lanlian ertong qingre cataplasm. METHODS:Taking adhesion force,peel strength and sensory description as index,the ratio of matrix framework material(sodium polyacrylate-gan hydroxyl alu-minum-tartaric acid-glycerin) was optimized with orthogonal test. The single factor test was adopted to select adhesive and filler;the amount of penetrating agent azone was screened using the in vitro penetration amount of phillyrin. RESULTS:The best matrix ratio of Lanlian ertong qingre cataplasm was sodium polyacrylate-gan hydroxyl aluminum-tartaric acid-glycerin(4.0:0.8:0.4:15);PVP K-90 was used as adhesive,and bolus alba as filler;penetration enhancers azone accounted for 2.0%. Validation test showed, prepared cataplasm had good appearance,could stick on the 5th or the 6th ball;it's peel strength was 7.5 N;all RSDs of score were lower than 4%(n=3). CONCLUSIONS:The optimized matrix formula of Lanlian ertong qingre cataplasm is simple,stable and good in molding.

Objective To investigate the relationship of peroxisome proliferator activated receptor gamma ( PPAR?)C161T gene polymorphism with related diseases of metabolic syndrome. To disscuss the mechanism of the elderly diseases from gene level and the relation between the gene polymorphism and lipid metabolism. Methods Three hundred seventy one non-sibship subjects of Han nationality were investigated in this study, including 69 old healthy subjects, 302 elderly cases diagnosed as metabolic syndrome. PPAR? C161T gene polymorphism was determined by polymerase chain reaction and restriction fragment length polymorphism, and radioimmunoassay was used to detect serum insulin. The insulin resistance was obtained from homeostasis model assessment (HOMA), and blood glucose, blood lipoprotein, height, weight and so on were tested. The frequencies of PPAR? C161T genotypes and the allele were compared with the clinical data. Results (1) In the groups of old normal health and metabolic syndrome, "T" allele frequency was 0.217,0.201, and "C" allele frequency was 0.783, 0.798 . There was no significant difference between the groups. (2)The triglyceride in CC genotypes of the metabolic syndrome was significantly higher than that in "T" allele carriers. Conclusions (1) The distributing trend of PPAR ? C161T gene polymorphism of the Han nationality in Wuhan in the elderly normal healthy group was in accord with that in the group of the elderly metabolic syndrome. (2) PPAR ? C161T substitution can influence metabolic syndrome, especially in liporprotain metabolism. "T" allele is associated with lower level of triglyceride.

Objective To study and evaluate the diagnostic and differencial diagnostic value of detection of human telomerase reverse transcriptase(hTERT) mRNA and telomerase activity in pancreatic juice of (pancreatic) cancer(PC) .Methods hTERT mRNA expression and telomerase activity in pancreatic juice in 24 cases of (pancreatic) cancer and 14 cases of chronic pancreatitis(CP) were detected and compared.Results Expression of hTERT mRNA was detected in 87 .5% (21/24) of PC cases and 21.4%(3/14) of CP cases(P

The experience in diagnosis and treatment of bleeding complications in severe acute pancreatitis (SAP) by transcatheter arterial embolization was summarized. The clinical data of 19 SAP patients complicated with intra-abdominal bleeding in our hospital from Jan. 2000 to Jan. 2003 were analyzed retrospectively and the therapeutic outcome of TAE was evaluated statistically. The results showed that the short-term successful rate of hemostasis by TAE was 89.5% (17/19), the incidence of re-bleeding after TAE was 36.8% (7/19) and the successful rate of hemostatis by second TAE was 71.4% (5/7). It was concluded that the intra-abdominal bleeding in SAP was mainly caused by the rupture of erosive/infected pseudoaneurysm. Mostly, the broken vessels were splenic artery and gastroduodenal artery; In terms of emergence hemostatis, TAE is the most effective method. Surgical hemostasis is necessary if hemostasis by TAE is failed or re-bleeding occurs after TAE.

The proliferation and differentiation of pancreatic duct epithelial cells in remnant pancreas during regeneration after partial pancreatectomy in rats were studied, and the source of pancreatic stem cells was characterized. Partial (90 %) pancreatectomy was performed on 4- to 5-week-old Sprague-Dawley rats, and different duct epithelial cells and acinar cells were detected by immunohistrochemical stain method and scored using 5-bromo-2'-deoxyuridine (BrdU) labeling index (LI) at various time points after partial pancreatectomy. It was found that at 24 h after partial pancreatectomy proliferation started in the main, large and small duct cells, and persisted in small duct cells to day 5. There was significant difference between the experimental group and the control group (P<0.001). Acinar cells positive for BrdU were greatly increased and reached the peak LI on day 5. The destroyed lobular architecture almost totally recovered on day 7, and the newly islet cells appeared around the pancreatic ducts. These results suggest that regeneration after partial pancreatectomy is involved in proliferation and differentiation of pancreatic stem cells, and pancreatic stem cells may locate in the pancreatic ductules.
