Objective To investigate the expressions of CYCLIND1 CDK4 in pancreatic cancer and their relationship with clinlicopathological parameters.Methods Immunohistochemical detector with new second generational tow steps method was used to detect the expressions of CYCLIND1 CDK4 and PCNA in 48 cases of pancreatic cancer and 14 cases of chronic pancreatitis.Results The expressions of CYCLIND1 CDK4 proteins in pancreatic cancer were 70.85%(34/48)and 62.50%(30/48) respectively.The CYCLIND1 and CDK4 proteins were increased(P

Bartter′s syndrome(BS) is a rare renal tubular diseases and an autosomal recessive hereditary disease. The characteristic findings are hypokalemia, metabolic alkalosis, and raised serum renin and aldosterone levels. Combination of metabolic syndrome with Bartter′s syndrome has not been reported so far. Here in, we report a case in order to call attention to the diagnosis and treatment of typical Bartter′s syndrome combined with metabolic syndrome.

The paper described the necessity of the doctor-patient information exchange platform,and defects found in existing platforms. Such a platform is conducive to higher hospital informationization, better patient satisfaction, and better social and economic benefits of the hospital.The hospital may improve its quality of care and patient satisfaction by means of the platform

Objective To sequence the antigen-encoding genes esxA,fbpB and Rv2660c from clinical isolates of Mycobacterium tuberculosis (MTB) in tuberculosis children and study the polymorphisms.Methods A total of 135 isolated strains were amplified for gene sequences of esxA,fbpB and Rv2660c by PCR,and the products were sequenced respectively.The results of sequencing were compared with the corresponding gene sequences of standard strain H37Rv and human T and B cell epitope sequences from immune epitope database (IEDB).The genetic diversities of the gene sequences of esxA,fbpB and Rv2660c were analyzed.Results Among the 135 strains,no gene polymorphisms were found in esxA and Rv2660c.But fbpB had genetic diversities in 66 clinical isolates (48.89％).The 5 single nucleotide polymorphism (SNP) mutations in fbpB affected 8 (14.81％) T cell epitopes and 9 (24.32％) B cell epitopes.The dN and dS values of whole fbpB gene were 0.000 120 and 0.002 126,respectively.The dN and dS values of T epitopes areas were 0.000 067 and 0.002 382 respectively,those of non-T epitopes area were 0.000 408 and 0.000 470,respectively,those of B epitopes areas were 0.000 063 and 0.00 2380,and those of non-B epitopes areas were 0.Conclusion The gene sequences of esxA and Rv2660c are conservative,and that of fbpB contains genetic diversities.Its polymorphisms may influence the function of antigen Ag85B,and thus affect the efficacy of vaccine H56.

Objective:To study performed of develop a mice model of allergic diseases induced by crude extractings from populus pollen.Methods: A total of 60 BALB/c mice were divided randomly into there groups:normal control group,Albumin Egg(OVA) group and populus pollen model group with 20 in each.Mices were repeatedly sensitized by intraperitoneal injections of OVA or crude populus pollen extract every 5 d for four doses.Five days after the last sensitization,mices were repeatedly challenged by once daily antigen from 21-25 d.The changes of inflammatory cells in bronchoalveolar lavage fluid(BALF) were stained with hematoxylin and eosin(HE) to evaluate the degree of allergic inflammation.PAS staining was used to observe the secretion of airway mucus;The changes of the nasal mucosas and lungs of mice were stained with HE to evaluate the degree of allergic inflammation.And the average optical density of IL-4 and IFN-γ positive cells in lung tissue was measured by immunohistochemistry.The total IgE in the serum was also measured by enzyme-linked immunoassay(ELISA).Results: Compared with the mice in normal control group,those in OVA group and model group developed obvious allergic inflammation in the nasal mucosas and lungs,and increased airway mucus secretion.The number of inflammatory cells including eosinophil and neutrophils markedly increased in BALF smear.The average optical density of IL-4 positive cells in lung tissue was all increased in OVA group and model group compared with those in normal control group,and the average optical density of IFN-γ in lung tissue was on the contrary.The total IgE in the serum were all increased in OVA group and model group compared with those in normal control group,and the IFN-γ in the serum was significantly reduced in OVA group and model group compared with those in normal control group.Conclusion: Taken together,crude populus pollen extract can successfully induce a mice model of allergic diseases.This model is a useful tool in studying the mechanisms of allergic disease.

Objective To study the current incidence of Keshan disease in Yunnan Province,and provide scientific basis for Keshan disease(KD) prevention and control. Methods Based on the Scheme of KD Surveillance, 16 villages in 11 counties were chosen as surveillance sites by the historical data. An survey was made to the residents in the 16 surveillance sites by filling in the questionnaire, inquiry medical history, clinical examination, electrocardiogram and 2 meters post-anterior chest X-ray for suspected cases. KD cases were diagnosed according to the Diagnostic Criteria for Keshan Disease(GB 17021-1997). The prevalence data of KD in the whole province were collected from the KD case report in 2007 and the trace surveys. Results There were 6877 residents in 16 surveillance sites of 11 surveillance counties and totally 39 KD cases were diagnosed with a detection ratio of 0.57% (39/6877). The detection ratio of latent and chronic KD were 0.41%(28/6877) and 0.16%(11/6877), respectively and no acute or subacute cases were found. The cases aged 5 to 14 years old accounting for 66.67% (26/39). Electrocardiogram examination of 6877 residents were made and 5.25% (361/6877) abnormal electrocardiograms were detected in the 16 surveillance sites. Fifty-five people were checked by chest X-ray and there were 31 cases with heart-chest ratio ≤0.50, 16 cases with heart-chest ratio from 0.51 to 0.55 and 8 cases with heart-chest ratio from 0.56 to 0.60. The prevalence rate and incidence rate of chronic KD were 4.24 per 100 000 and 0.50 per 100 000 in Yunnan. No acute or subacute cases were found and the latent cases were listed. The prevalence rate and incidence rate were 7.76 per 100 000 and 1.18 per 100 000 in the 16 surveillance sites. Conclusions The incidence of KD is low incidence in Yunnan Province. Higher ineidence of chronic KD was detected in the some areas and the corresponding control measures need to be adopted.

Objective In order to master the current situation of Keshan disease in Yunnan province and to provide scientific basis for Keshan disease control and prevention. Methods Eighteen villages were selected as the investigation sites in 6 counties across all the Keshan disease wards in Yunnan province,where the residents were investigated. Then,the villages census data was collected,clinical examination aiming mainly on cardiovascular system was carried out,including electrocardiography and X-ray to the suspected patients. Correct diagnose of Keshan disease was made by the Diagnostic Standard of Keshan Disease(GB 17021-1997). At the same time,10 food samples and 10 hair samples for detecting selenium content in every investigation site. Results There were 9818 residents investigated in the 18 investigation sites in 6 counties,and 34 eases of Keshan disease were found,the total incidence rate was 0.35%(34/9818). Among the 34 Keshan disease eases,32 cases were latent Keshan disease,the incidence rate was 0.33%(32/9818); 2 cases were chronic Keshan disease,the incidence rate was 0.02%(2/9818). There was no any acute and sub acute cases be found. Most Keshan disease cases aged from 5 to 14,67.65% (23/34). Abnormal ECG rate was 6.90% (677/9818). Among 56 X-ray films,47 cases had a cardiothoracic ratio less than or equal to 0.50,83.93%(47/56),5 cases from 0.51 to 0.55,8.93%(5/56),4 cases from 0.56 to 0.60,7.14%(4/56). Selenium content was detected in 180 food samples and 180 hair samples. The average food selenium content (mg/kg) was 0.013±0.010,the lowest content in Yongsheng county (0.006± 0.001),the highest content in Tonghai county(0.027±0.009). The average hair selenium eontentwas(0.252± 0.078)mg/kg,with the lowest(0.145±0.043)mg/kg in Yoagsbeng county,the highest (0.297±0.062)mg/kg in Tonghai county. Conclusions The detected ratio of Keshan disease is low in Yunnan province. Most of Keshan disease patients age from 5 to 14. It was presented that the Keshan disease infectious agents were still strong and active. The foodstuffs and hair Selenium content is low in food and hair sample,and varies in different investigation site. It is necessary to supply selenium for prevent Keshan disease in the severe areas.
