OBJECTIVETo observe the effect of Weichang'an (WCA, a Chinese preparation) in preventing post-operative metastasis of progressive stage of gastric cancer.

METHODSA prospective randomized, controlled study was conducted by dividing the 148 patients of progressive staged gastric cancer after radical operation into the WCA group, the chemotherapy (CT) group and the WCA + CT group, to observe the survival rate, metastasis rate, quality of life (QOF) and tumor-bearing survival time after relapse (TST) in patients.

RESULTSThe 1-, 2- and 3-year survival rate after operation in the WCA + CT group was 89.51%, 69.77% and 55.76% respectively, which was significantly higher than that in the CT group (83.86%, 59.33% and 49.43%) respectively (P < 0.05), but showed insignificant difference as compared with that in the WCA group (93.23%, 79.34% and 71.78%). Only 1-year metastasis in the WCA group was 15.25%, and in the WCA + CT group was 15.52%, the two were significantly lower than that in the CT group (35.48%, P < 0.05). But the comparison of 2-year metastasis rate among the 3 groups (28.81%, 41.38% and 45.16%) and 3-year metastasis rate among them (33.90%, 46.55% and 51.61%) were insignificantly different. The QOF and TST were markedly better in the WCA group than those in the CT group.

CONCLUSIONWCA has preventive effect on relapse and metastasis in post-operational gastric cancer patients.

Objective To understand the mycoplasma pneumoniae(MP) infection degree in community children by testing specific IgM antibodies against MP in different age bracket group in Shanghai Meilong area. Methods Using random sampling method, blood specimens of 1 817 children from kindergartens and primary or junior high schools in Meilong area were obtained. Children were from 2 to 15 years old, 969 males, 848 females. The specimens were tested for IgM antibodies against MP using with gelatin particle agglutination test. The data were statistically analyzed using with ?2 test. Results Five hundred and fifty-nine (30.7%) IgM antibodies against MP were positive from 1 817 blood specimens. The positive percentages were 27.34% and 34.66% for males and females, which had significant difference(?2=11.383 P=0.001). The higher percentage was detected from kindergarten children than primary and junior high school children(P=0). The positive percentages of anti-mycoplasma IgM had no significant differences between different kindergartens and primary schools(P=0.526,0.232). On the contrary, between different junior high schools, there were siginificant differences (?2=9.825 P=0.002). Conclusions MP is an important pathogenic mycoplasma cause for respiratory tract infections in Meilong area. It is relative to childhood asthma. The prevention and cure of MP infection for children shall be paid more attention.

Diffuse pulmonary lymphangiomatosis (DPL) is a rare disease that is characterized by diffuse proliferation of abnormal pulmonary lymphatic channels. DPL occurs mostly in children and young adults and often undergoes a progressive clinical course, eventually causing deterioration of the lung. Both the clinical diagnosis and treatment of DPL remain a challenge. Here, we report a case of DPL in a 53-year-old Chinese woman with comprehensive investigations including pulmonary function tests, computer tomography (CT), bronchoscopy and histological examination of the lung biopsy, and review the literature.

BACKGROUNDPrognosis of patients with acute ST-elevation myocardial infarction (STEMI) and renal dysfunction (RD) who received primary percutaneous coronary intervention (PCI) has not been fully investigated in the drug-eluting stent (DES) era. This study aimed to evaluate the impact of admission serum creatinine level on short-term outcomes in patients with acute STEMI undergoing DES-based primary PCI.

METHODSPrimary PCI with DES implantation was attempted in 619 consecutive STEMI patients within 12 hours of symptom onset. Among them, 86 patients had a serum creatinine level > or = 115 micromol/L on admission (RD group), and the remaining 533 patients had normal renal function (non-RD group). The primary endpoint was 30-day major adverse cardiac events (MACE, including death, non-fatal reinfarction, and target vessel revascularization), and the secondary endpoint was subacute stent thrombosis.

RESULTSPatients in the RD group were older than those in the non-RD group. There are more female patients in the RD group and they had a history of hypertension, myocardial infarction and revascularization. The occurrence rates of Killip class > or = 2 (29.1% vs 18.6%, P = 0.02) and multi-vessel (62.8% vs 44.5%, P = 0.001) and triple vessel disease (32.6% vs 18.2%, P = 0.002), in-hospital mortality (9.3% vs 3.8%, P = 0.03), and MACE rate during hospitalization (17.4% vs 7.7%, P = 0.006) were higher in the RD group than those in the non-RD group. At a 30-day clinical follow-up, the MACE-free survival rate was significantly reduced in the RD group (76.7% vs 89.9%, P = 0.0003). Angiographic stent thrombosis occurred in 3 (3.5%) and 7 (1.3%) of patients in the RD group and non-RD group, respectively (P = 0.15). Multivariate analysis revealed that the serum creatinine level > or = 115 micromol/L on admission was an independent predictor for MACE rate at a 30-day follow-up (Hazard ratio (HR) 3.31, 95% CI 1.19 - 9.18, P < 0.001).

CONCLUSIONDespite similar prevalence of stent thrombosis at a 30-day clinical follow-up, the short-term prognosis of STEMI patients with elevated serum creatinine on admission undergoing DES-based primary PCI remains unfavorable.

OBJECTIVETo summarize clinical and molecular features of two children with autosomal recessive chronic granulomatous disease caused by CYBA mutations.

METHODThe clinical records and CYBA mutations were reviewed for analysis of infections and inflammatory complications.

RESULTThe first case was a girl diagnosed with "liver and spleen abscess" in our hospital when she was 2.9 years old, with past history of neonatal impetigo and recurrent purulent lymphadenitis and positive family history. The results of DHR123 flow-cytometry showed that positive phagocytes after phorbol ester (PMA) stimulation was 84.63%. CYBA mutation analysis showed that she had heterozygous 35C > T, Q3X and IVS-2A > G. The second case was a boy diagnosed with "sepsis (salmonella D)" when he was 4 years old with a past history of impetigo, sepsis, perianal abscess, skin infection and positive family history. The results of flow cytometry showed that positive phagocytes after PMA stimulation was 96.13%. CYBA mutation analysis showed that he had homozygous 35C > T, Q3X and his parents were all carriers. All of them had BCG related axillary lymphnode calcification.

CONCLUSIONA22CGD cases had recurrent purulent infections (skin, lymphnode, liver and spleen, lung, blood), DHR123 flow cytometric analysis helped the diagnosis of CGD, CYBA mutation analysis ascertained the diagnosis of A22CGD.

OBJECTIVETo investigate the expression of chemokine receptor CXCR4 in colorectal carcinoma and its relationship with the clinicopathological parameters, and to reveal the role of CXCL12/CXCR4 in the invasion and metastasis of colorectal carcinoma.

METHODSCXCR4 expression was studied in 53 colorectal cancer tissues and 27 normal tissues by immunohistochemistry. Its relationship with clinicopathological characteristics of colorectal cancer patients were analyzed. The CXCR4 expression in tumor and normal specimens and its metastatic sites were assessed by RT-PCR and Western blot.

RESULTSFifty-three colorectal cancer patients,collected from July 2005 to February 2007 in our hospital,were enrolled in this study. CXCR4 was positive in 39 cancer tissue specimens(73.6%) and its high expression rate (in > 50% of cells) was 45.3%. High CXCR4 expression rate was significantly higher in patients with lymph node metastases (N(1)+N(2): 65.4%) than that in those without metastases(N(0) 25.9%). There were also associations between the high CXCR4 expression and the vascular and lymphatic vessel invasions (P<0.01). Meanwhile, there was a rising trend of high expression rate according to American Joint Committee on Cancer (AJCC) stage and pathologic grade,but no significant difference was found(P>0.05). There were no significant correlation of CXCR4 expression with clinicopathological parameters such as tumor location, tumor size, depth of tumor invasion(P>0.05). In addition, the CXCR4 mRNA expression in primary tumor specimens (n=27) from AJCC stage IIII( patients was significantly higher than that in normal tissues. CXCR4 mRNA expression of liver metastasis specimens(n=5) was significantly higher as compared with the primary colorectal cancer specimens(P<0.01).

CONCLUSIONSChemokine receptor CXCR4 is associated with the progression of colorectal carcinoma. High CXCR4 expression is associated with metastasis. The CXCL12-CXCR4 signaling pathway may be a potential novel target of therapy for patients with colorectal cancer.

OBJECTIVETo analyze the relationships among the aberrant methylation of Runx3 gene promoter, the Runx3 protein expression and clinicopathological features in gastric cancer.

METHODSMethylation specific PCR was used to measure the promoter methylation status of Runx3 gene in tumor and the adjacent normal mucosal tissues from 40 patients with gastric cancer. Protein expression of Runx3 was measured by immunohistochemistry.

RESULTSThe frequency of promoter methylation of Runx3 gene in gastric cancer tissue(55.0%) was significantly higher compared to the adjacent normal tissues (12.5%)(P<0.01). The positive rate of protein expression of Runx3 in gastric cancer tissue(37.5%) was significantly lower compared to the adjacent normal tissues (100%). There was marked association between hypermethylation and negative protein expression (P<0.05). The frequency of Runx3 promoter methylation was associated with histological type, N grade, and tumor stage.

CONCLUSIONThe promoter hypermethylation is a main mechanism of reduced or loss expression of Runx3 gene, which may provide molecular diagnosis and stage evaluation of gastric cancer.

OBJECTIVETo analyze the prevalence of asthma and asthma related symptoms among children aged 0-14 years in three Chinese cities and to obtain a crude estimation of the trend of childhood asthma prevalence in China.

METHODSA cross-sectional, population-based survey of prevalence of asthma was conducted in children aged from 0 to 14 years in 3 major cities of China (Beijing, Chongqing, and Guangzhou) with different geographic locations. All the subjects were randomly selected by a multi-stage sampling method. Three to five schools and kindergartens in 2 urban districts in each city were randomly selected for the survey, and a validated questionnaire that included the core questions of the International Study of Asthma and Allergies in Childhood, Phase III questionnaire and several additional questions were used. All questionnaires were completed by parents or guardians of the selected children. Children whose parents responded affirmatively to the question "Has your child ever been diagnosed as asthma by a doctor" were recognized as victims of asthma.

RESULTSThe prevalence of asthma in Beijing, Chongqing, and Guangzhou was 3.15%, 7.45%, and 2.09%, respectively. These values were significantly higher than those obtained 10 years ago in the national epidemiological survey in 2000 which used the same method of investigation and the same diagnotic criteria (χ²=3.938, P=0.047; χ²=73.506, P≤0.001; χ²=11.956, P=0.001, in each city). Of the asthmatic children 57.21%, 69.91%, and 60.00% had their first attack before the age of 3 in Beijing, Chongqing, and Guangzhou, respectively. Wheezing was the primary clinical manifestation for all asthmatic children, followed by persistent cough and repeated respiratory infections. Both the prevalence of asthma and asthma-related symptoms were statistically higher in males than in females.

CONCLUSIONThe prevalence of childhood asthma is statistically higher than that 10 years ago in the three Chinese cities.
