Objective To investigate the prevalence of urticaria among children aged 2-6 years in Nanjing city.Methods A questionnaire survey was carried out in children aged 2-6 years in 5 main districts of Nanjing City.Results The number of valid questionnaires was 13 610,accounting for 92.8％ of total respondents.Among the 13 610 respondents,1 116 were diagnosed as urticaria,including 565 boys and 551 girls,with the total prevalence rate being 8.54％.No significant difference was observed in the prevalence rate of urticaria between boys and girls (8.49％ vs.8.60％,x2 =0.04,P =0.832) or among children of different age groups (x2 =1.84,P =0.17).The prevalence of urticaria increased with age,and positively correlated with parents' educational level (rs =0.96,P =0.000).Children born in urban areas showed higher prevalence of urticaria than those in rural areas (8.79％ vs.5.56％,x2 =13.98,P =0.000).Conclusions The prevalence of urticaria has increased among children aged 2-6 years in recent years.More studies should be carried out to investigate into the pathogenesis and relevant factors of urticaria,so as to facilitate its prevention and treatment.

Objective To investigate the prevalence of atopic dermatitis (AD) among children aged 2-6 years in Nanjing city.Methods A questionnaire survey was carried out in children aged 2-6 years in 7 main districts of Nanjing City.Results A total of 13 061 children were investigated,among which,768 were diagnosed as AD,including 410 boys and 358 girls.The prevalence rate of AD was 5.88％ (95％ CI,5.48％-6.28％) in total,6.16％ (95％ CI,5.59％-6.74％) in boys and 5.59％ (95％ CI,5.02％-6.15％) in girls.Higher prevalence rate of AD was observed in boys compared with girls,and in children whose place of birth was in urban areas compared with those in rural areas.In addition,the prevalence rate of AD increased with age and with the rise in parental educational level.Conclusions Rapid economic development has dramatically changed life habits,dietary structure and residential environment of people,which can influence the prevalence of AD.

Objective To investigate the three-dimensional structure of normal male canine prostat- ic duct and acinus system,and to study the mechanism of intraprostatic urinary reflux(IPUR)resulting from high pressure of the posterior urethra by experiment.Methods Using scanning electron microscopy (SEM)and corrosion casting methods,high pressure of the prostatic urethra was produced based upon IPUR in normal male canines.Acrylonitrile-butadiene-styrene(ABS)casting solution was injected into 8 Beagle canines'normal prostates to induce intraprostatie resin solution reflux.Results Six casting molds of nor- real canine prostate specimens were obtained,and the casting failed in 2.By corrosion and casting treatment, the prostate appeared to consist of several glandular lobes.The columnar apophyses of glandular surface were observed.The most glandular ducts pointed outward from urethral peristome.Each glandular duct system was made up of many bifurcated branches from the bough as a duct tree.More than 90% of the bifurcations were Y-shaped,and 6 bifurcated branches were rarely seen.The tip of the duct was vesicular.The diameter and length of the bough were(0.37?0.14)mm and(1.14?0.04)mm,respectively.The intersectional angle of urethra and peripheral glandular duct was the biggest.Peripheral glandular duct was perpendicular or con- verse to urinary flow.Peripheral glandular aeinus appeared elliptic and velvet.The mesh-like and crater-like depressions were shown on the surface of central glandular aeinus.Ejaculatory ducts independently and branchlessly entered the urethra.Conclusions The resin corrosion casting methods combined with SEM can clearly show the three-dimensional structure of normal male canine prostatic duct and acinus system. IPUR may easily occur in the peripheral glands from the morphological view.It is suggested that prostatitis occurs more commonly in peripheral glands,confirming a fact that high pressure of the posterior urethra can induce IPUR.

OBJECTIVETo observe clinical results of Chinese herbs promoting blood circulation and removing blood stasis on the treatment of reflex sympathetic dystrophy (RSD) with type of stagnation of vital energy and blood stasis.

METHODSRSD with type of stagnation of vital energy and blood stasis was distinguished as erubescence, high temperature, perspiration, damp and acro-edema, with middle level pain. From 2006 to 2008, 58 patients with RSD of stagnation of vital energy and blood stasis were randomly divided into the treatment group (30 cases) and the control group (28 cases). The former were treated with Chinese medicine to activate blood circulation and improve bone and muscle nourishment. Chinese medicine includes: Caesalpinia Sappan 10 g, Ligusticum Chuanxiong 6 g, Frankincense 6 g, Angelica 10 g, Safflower 6 g, Myrrh 6 g, Ground Beetle 10 g, Araliaceae 3 g, Radix Paeoniae Rubra 10 g, Pericarpium Citri Reticulatae 5 g, Lawn Pennywort Herb 15 g, Manis Pentadactyla 10 g, Corydalis Yanhusuo 10 g, Rhizoma Drynariae 15 g, which were boiled into decoction and the patients were take orally everyday with a course of treatment for 10 days, together with the boiled Chinese traditional medicine of stretching muscle and activating blood circulation to fume and wash the limbs twice everyday. The compatibility of medicines in prescription includes: Lycopodium Japanicum Grass 10 g, Gentiana Macrophylla Pall 10 g, Radix Angelicae Pubescentis 10 g, Angelica 10 g, Uncaria 10 g, Frankincense 6 g, Myrrh 6 g, Safflower 6 g. Control group were treated with a placebo of the same color for oral use and external application. The delivery times, method and the time of therapy were all the same as the treatment group. After 30 days' treatment, the effective indexes of VAS pain score and swelling condition were observed in both groups.

RESULTSVAS pain score: the treatment group decreased (3.8 +/- 0.8) points and the control group decreased (1.0 +/- 0.3) points, the difference between the two groups was significantly (P < 0.01). There was significantly difference in volume decrease of the swelling limb between treatment group (21.8 +/- 2.5) ml and the control group (10.3 +/- 2.1) ml (P < 0.01). The efficiency difference between treatment group and control group was significantly(P<0.01).

CONCLUSIONWith the different treatment based on different syndrome and emphasis on the nourishment of bone and soft tissue, treated by Chinese medicine to promote blood circulation and remove blood stasis in stagnation of vital energy and blood stasis, RSD get a favorable result.

OBJECTIVETo investigate the incidence, risk factors and preventative methods associated with chyle leak following complete mesocolic excision(CME) for colon cancer.

METHODSClinical data of 592 patients with colon cancer undergoing CME in the department of Colorectal Surgery in the Fujian Medical University Union Hospital from September 2000 to September 2011 were analyzed retrospectively.

RESULTSChyle leak occurred in 46 patients(7.7%). The incidence of postoperative chyle leak following right CME hemicolectomy was 13.3%(30/226), significantly higher than that after left CME hemicolectomy (4.4%). On univariate analysis, chyle leak following CME was associated with tumor size(P<0.05), tumor location(P<0.01), and lymph nodes harvested(P<0.01). Multivariate logistic regression revealed that tumor location and lymph nodes harvested were independent risk factors associated with chyle leak following CME(P<0.05).

CONCLUSIONSTumor location and lymph nodes harvested are independent risk factors for chyle leak following complete mesocolic excision for colon cancer. When the drainage output suddenly increases after oral intake resumption, the chyle test of ascitic fluid should be performed for early diagnosis and prompt management.

OBJECTIVETo investigate regulation function of anodonta glucan HBP-A on chondrocytes through Wnt pathway in vitro.

METHODSRat chondrocytes were cultured and differentiated induced with IL-1beta (10 ng/ml) in vitro. Chondrocytes were divided into five groups:IL-13 group,IL-1beta + IWP-2 (5 microM,Wnt pathway inhibitor) group, IL-1beta + HBP-A (0.3 mg/ml) group and IL-1beta + IWP-2 + HBP-A group. Wnt-3a, beta-catenin (24 h,48 h,72 h) and MMP-13(72 h) genes expression were detected by Rt-PCR, while beta-catenin, MMP-13, Sox-9 and coll-II (48 h) protein expression were measured by Western-blot.

RESULTSAfter induction of IL-1beta, gene expression of Wnt-3a, beta-catenin and MMP-13 were increased,so were the protein expression of beta-catenin and MMP-13. In contrast,protein expression of Sox-9 and Coll-II were declined. Following addition of HBP-A, Wnt-3a, beta-catenin and MMP-13 were shown as induction of IL-1beta, but protein expression of Sox-9 and Coll-II were upgraded. Combining HBP-A with IWP-2 led to the lowest level in Wnt-3a, beta-catenin gene and beta-catenin protein expression and highest expression of Sox-9 protein.

CONCLUSIONHBP-A could not only delay the differentiation of chondrocytes through downgrading the signal expression of Wnt/beta-catenin,but also adjust the expression of Wnt-3a, beta-catenin and Sox-9 when combinated with the Wnt inhibitor.

Objective:To understand the molecular characteristics and correlation among isolated strains of Brucella melitensis (BM) so as to improve the strategies on prevention and control of the disease in Jiangxi province. Methods:A total of 25 strains of BM isolated from human in 17 counties of Jiangxi province were analyzed by multiple locus variable-number tandem repeat analysis (MLVA) method.Results:A total of 25 strains of BM were classified into 24 independent genotypes with similarities between 67.00% and 100.00% and Simpson index between 0.000 and 0.773. There were 3 genotypes in MLVA8, including 60.00% (15/25) as 42 genotype, 32.00% (8/25) as 43 genotype, and 8.00% (2/25) as 63 genotype, respectively. There were 7 genotypes in MLVA11 identified, with 116 genotype and 125 genotype the main genotypes, accounting for 56.00% (14/25) of all the identified strains.Conclusions:Genes from all the 25 strains of BM that isolated from human being were with high genetic diversities, and various, genotypes. However, no obvious epidemiological correlation was noticed among these strains, indicating the complexity of the source of infection on Brucella in Jiangxi province.

OBJECTIVETo explore the differences in long-term outcomes between laparoscopic and open complete mesocolic excision(CME) for colon cancer.

METHODSA total of 273 patients with colon cancer who underwent CME at the Fujian Medical University Union Hospital from September 2000 to December 2008 were divided into laparoscopic(LP, n=147) and open(OP, n=126) groups in a non-random manner. The oncologic and long-term outcomes were compared.

RESULTSNo significant differences were seen in the length of distal and proximal margin, and number of lymph nodes(all P>0.05). Median postoperative follow up was 50 months. Local regional recurrence rates (LP 6.1% vs. OP 7.9%) and distal metastasis rates(LP 23.8% vs. OP 16.7%) were similar between the two groups(all P>0.05). The 5-year overall survival rates (LP 69.4% vs. OP 74.0%, P=0.840) and 5-year disease-free survival rates(LP 68.5% vs. OP 70.9%, P=0.668) between the two groups were not statistically different.

CONCLUSIONSLaparoscopic CME has the same oncologic clearance effects compared with open CME for colon cancer. It might become a new standardized surgery for colon cancer.

OBJECTIVESTo investigate the expression of P120 catenin in pancreatic carcinoma and to explore the association between P120 catenin gene polymorphism at T755G position and pancreatic carcinoma.

METHODSThe expression of P120 catenin in 52 cases of pancreatic carcinoma and normal pancreatic tissues on the mRNA and protein levels were evaluated by RT-PCR and Western Blot methods respectively. P120 catenin gene polymorphism at T755G position of in 52 patients and 60 healthy controls were examined by PCR-restriction fragment length polymorphism (PCR-RFLP) technique.

RESULTSThe mRNA and protein expressions of P120 catenin in pancreatic carcinoma tissues were significantly lower than normal pancreatic tissues (P=0.000, P=0.002). Reduced expression of P120 catenin mRNA was significantly correlated with differentiated (P=0.033), lymph node metastasis (P=0.004), vascular invasion (P=0.022), and pTNM stage (P=0.003). Additionally, there were significant difference of P120 catenin gene polymorphism genotypes and alleles at T755G position between patients and healthy controls (P=0.008, P=0.016). The GG genotype of P120 catenin gene was associated with higher risk of incidence for pancreatic carcinoma compared with the TT genotype (OR=2.765, 95%CI=1.312-3.958).

CONCLUSIONSThe reduced expressions of both P120 catenin mRNA and protein in pancreatic carcinoma suggest its association with pancreatic carcinoma development. Polymorphism of P120 catenin gene at T755G situation might be a risk factor for pancreatic carcinoma, and it may be used to diagnosis and prevent pancreatic carcinoma early.
