Objective To approach the relationship of the expression of hepatocyte growth factor (HGF)/c-met and clinical characteristics of patients with ovarian tumor. Methods Immunohistochemistry (SABC)was used to detect the expressions of HGF and c-met in different pathology group with ovarian cancer. Results HGF positive cells are chromatosised to yellow and take strong expression in the ovarian cancer tissue. C-met takes strong expression in epithelial cell and amply-chromatosis in interstitial cell. HGF and c-met have significant deviation in ovarian tumors, commissurotome tumors and benign tumors (P

Objective To study the expression of CDK4 andβ-Catenin and their relevance in glioma. Methods We used immunohistochemistry to detect the expression of CDK4 andβ-Catenin in forty-five glio-ma tissues and eight normal tissues.According to the classification standard of WHO in 2000 classify and grade the tissues.Results There were significant differences of CDK4 andβ-Catenin expressions between normal tis-sues and glioma tissues(P<0.01).The expression of CDK4 and β-Catenin had positive correlation with the pathological grades of glioma and histological type and increased(P <0.05).Furthermore,the expression of CDK4 was positively correlated with the expression ofβ-Catenin in glioma(r=0.52,P<0.01).Conclusion The increased expression of CDK4 andβ-Catenin may have correlation with malignant change of glioma and oc-curance of glioblastoma,and their combination is expected to become an important indicator in assessing malignant glioma.

Objective To investigate the case of left-semicolon cancer with intestinal obstruction for the methods of one-stage resection and anastomosis.Methods The clinical data of ten patients with left-semicolon can- cer with intestinal obstruction treated by transanus ilues tube,were restrospectively analyzed from October 2004 to December 2006.Results No postoperative anastormotic leakage was found and the patients were clinically cured. Conclusion The technical problem that left-semicolon cancer with obstruction for one-stage resection and anastomo- sis was resolved by the application of transanus ilues tube.

Objective To investigate the appropriate and pragmatic drainage after the breast cancer by radi- cal surgery.Methods 120 patients treated by the radical surgery from July 2003 to July 2005,were divided into the experimental group(ring-like double tubes with negative pressure drainage) and the control group(armpit single tube drainage with pressure bind).The differences between the two groups were analyzed in the same period,respectively sixty cases.Results The outflow of the first three days after operation in the experimental group was more than that in control group(P0.05).The incidence of sinoma and incision delaying healing in experimental group was lower than that in con- trol group(P

Objective To observe the effect of Bingdouting capsule(BC)on rabbit model of sick sinus syndrome.Methods Rabbit models of sick sinus syndrome were established by external application of 20 % methanal on the region of sinoatrial node.The effect of BC on heart rate and electrophysicological parameters of sinoatrial node was observed.Results BC markedly increased the heart rate,shortened the sinoatrial conduction time(SACT)and corrected sinoatrial node recovery time(CSNRT).Conclusion BC has an obvious effect for the treatment of sick sinus syndrome in rabbits.

BACKGROUNDHypogammaglobulinemia is common in infant humoral immunodeficiencies and has complicated causes and outcomes. We aimed to determine the clinical manifestations, immunological changes and outcomes of Shanghai infants with hypogammaglobulinemia.

METHODSPatients under 2 years old, having one or more warning signs of primary immunodeficiency disorders, serum immunoglobulin levels below the lower limit of reference range per age, and with normal numbers for lymphocyte subsets, were analyzed and followed up for 2 to 3 years.

RESULTSA total of 91 children (male-to-female ratio: 2.25: 1) participated in the study. Initial clinical presentation was recurrent upper respiratory tract infection (46%), invasive infection (3%), atopic disease (32%). IgA reduction (77%) was prevalent; 34% patients had more than one isotype reduced. During follow-up, 51 of 62 patients (82.25%) had immunoglobulins normalized at the age between 12 - 48 months; these were diagnosed as transient hypogammaglobulinemia of infancy (THI). Long-term follow-up may reveal a diagnosis for the remaining 11 infants with persistent lower immunoglobulin levels, who did not have antibody titers measured. Earlier onset was correlated with higher rates of normalization. More patients were diagnosed with isolated hypogammaglobulinemia in 2006 compared with the previous 4 years (2002 - 2005).

CONCLUSIONSThe awareness of immunodeficiency among pediatricians has been greatly improved. Recurrent otitis media was not a major infection in our patients. THI is a relatively common condition associated with infant hypogammaglobulinemia. In the absence of specific antibody titers, the diagnosis of THI can be confirmed retrospectively with Ig levels normalized in follow-up visits. Therefore, long-term follow-up and frequent re-evaluation of these patients are necessary to distinguish them from true primary immunodeficiency.

Pompe disease, also called type II glycogen storage disease, is a rare autosomal recessive inherited disease caused by the storage of glycogen in lysosome due to acid α-glucosidase (GAA) deficiency, with the most severe conditions in the skeletal muscle, the myocardium, and the smooth muscle. Patients may have the manifestations of dyspnea and dyskinesia, with or without hypertrophic cardiomyopathy. GAA gene mutation has ethnic and regional differences, and new mutation sites are found with the advances in research. Gene analysis is the gold standard for the diagnosis of Pompe disease. Conventional methods, such as skin and muscle biopsies and dried blood spot test, have certain limitations for the diagnosis of this disease. In recent years, prenatal diagnosis and newborn screening play an important role in early diagnosis of this disease. Enzyme replacement therapy (ERT) has a satisfactory effect in the treatment of this disease, but it may lead to immune intolerance. New targeted gene therapy and modified ERT will be put into practice in the future. This article reviews the research advances in the diagnosis and treatment of Pompe disease.

OBJECTIVETo examine the genetic polymorphisms in the promoter region of cyclooxygenase-2 ( COX-2) and evaluate their association with the risk of gastric cancer.

METHODSSingle-strand conformational polymorphism and DNA sequencing were used to screen the genetic variants of the COX-2 promoter region. Total 323 patients with gastric cancer and 646 frequency-matched controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism method. Odds ratios (OR) and 95% confidence intervals (CI) were estimated by logistic regression. Haplotype frequency was estimated using Haplo. stat software.

RESULTSThree single nucleotide polymorphisms, including - 1290A > G, -1195G > A, and -765G > C were identified in the promoter of COX- 2. Case-control analysis showed an increased risk of developing gastric cancer for the -1290AG (OR 1.64; 95% CI 1.03-2.61), -1195AA (OR 2.68; 95% CI 1.65-4.33), and -765CG (OR 2.66; 95% CI 1.53-4.64) genotype carriers, respectively, compared with noncarriers. A greater risk of developing gastric cancer was observed for the A(-1290) -A(-1195) -C(-765) haplotype compared with the A(-1290) -G(-1195) -G(-765) haplotypes (OR 11.80; 95% CI 2.43-57.25).

CONCLUSIONGenetic polymorphisms in COX-2 promoter region may play a role in gastric carcinogenesis.
