Objective To study the epidemiological features of the endemic arsenism in Hohhot of Inner Mongolia in 2004-2006 in order to get scientific evidence for the control and prevention. Methods The historical data in Huhhot revealed that 51 arsenic villages in 3 counties(Tumotezuo,Tuoketuo and Helingeer) were investigated. When arsenic content in drinking water was 0.05-0.15 mg/L,the situation of endemic arsenism was investigated in the households having high arsenic contents of water. When arsenic content in drinking water was greater than 0.15 mg/L,the survey was conducted to investigate arsenic patients with census. Census rate was not lower than 90%. Patients of endemic amenism were diagnosed by The Standard of Diagnosis for Endemic Arsenism (WS/T 211-2001). Results A total 28 083 people were examined,3978 were determined to be patients with arsenism,including 1722 being suspicious, 1897 mild,329 secondary and 30 severe. The total incidence of arsenism was 14.17% (3978/28 083),while the incidence of suspicious,mild,secondary and severe disease was 6.13% (1722/28 083) ,6.75% (1897/28 083),1.17% (329/28 083) and 0.11% (30/28 083),respectively. Suspicious and mild patients were most frequently seen. The incidence of dyspigmentation,pigmentation,ketatoses,both dyspigmentation and pigmentation and all of skin disorders was 8.65% (2428/28 083),3.19% (895/28 083),6.48% (1821/28 083),2.13%(598/28 083) and 0.94%(265/28 083),respectively. The most seen skin disorders were dyspigmentation and ketatoses. The disease mostly occurred in those aged over 40 years,the incidence was 89.52% (3561/3978). The incidence of male [15.08%(2209/14 644)]was more than that of female[13.16%(1769/13 439)].Conclusions Current condition of arsenism in Hohhot is mild,arsenic disease surveillance should keep going. Prevention and control needs to be reinforced in the future.

PURPOSETo explore the possible surgical factors related with nonunion in femoral shaft fracture following intramedullary nailing.

METHODSWe retrospectively analyzed totally 425 patients with femoral shaft fracture in level I urban trauma center, including 254 males and 171 females, with an average age of 37.6 (ranging from 21 to 56) years old. The inclusion criteria included: (1) traumatically closed fracture of femoral shaft, with pre- operative films showing non-comminuted fracture, such as transverse fracture, oblique fracture or spiral fracture; (2) closed reduction and fixation with interlocking intramedullary nail at 3-7 days after trauma; (3) complete follow-up data available. The relationship between the following factors (fracture site, reduction degree, direction of nail insertion and nail size) and nonunion was studied.

RESULTSThe incidence of femoral nonunion was 2.8% in patients with closed simple fracture undergoing interlocking intrameduallary nailing, including 11 cases of hypertrophic nonunion. Nonunion was related significantly to distal fracture, unsatisfactory reduction and unreamed nail (p < 0.05). There was no significant difference between antegrade nail and retrograde nail (p > 0.05).

CONCLUSIONSNonunion in femoral shaft facture following interlocking intramedullary nailing is related to fracture site, fracture reduction and nail diameter. The choice of reamed nails or unreamed nails depends on the fracture site and reduction degree.

OBJECTIVETo investigate the feasibility of using cartilage link protein of hyaluronic acid (HA-CLP) for defining the tumor boundary in a mouse model of lung carcinoma.

METHODSLung carcinoma was induced in KM mice by chemical carcinogenesis. HA-CLP separated from bovine cartilage and purified by affinity chromatography was labeled with (125)I for autoradiography. Immunohistochemical analysis and Western blotting were used to examine the efficiency of HA-CLP in defining the boundaries of the lung tumors.

RESULTSWith autoradiography, the clearest image of lung cancer was obtained at 2 h. With immunohistochemical method, the tumor boundary was the most clearly displayed at 2 h when the strongest signals of HA-CLP was detected; Western blotting also showed the clearest bands of HA-CLP at 2 h.

CONCLUSIONHA-CLP has the immunogenicity of HABP, and can efficiently indicate lung tumor boundary in autoradiography and immunohistochemistry.

Objective To investigate the medicinal plant group and resource of Sect. Euthya in Paris L. in Shaanxi Province. Methods Through literature analysis and interview survey, combined with line transect method, the medicinal plant group, the natural distribution and the status of medicinal plant group and resources about Sect. Euthya in the specific county territory in Shaanxi Province were investigated.Results According to related records about the medicinal plants of Sect. Euthya in Paris L. included P. polyphylla, var. stenophylla, var. apetala, and Paris fargesii var. petiolatain in Shaanxi Province. Based on field investigation, it was found that, the medicinal plants of Sect.Euthya in Paris L.also included five variations of P.polyphylla var.latifolia,var.apperdiculata,var. thibetica, var. chinensis, and var. yunnanensis, which were new distribution records. No var. apetala was found under field investigation. Most of the rhizomes of the Sect. Euthya plants were used as Chinese materia medica Paridis Rhizoma, with wide distribution and good growth condition. The natural resources of these plants are endangered. Conclusion In this study, two species and six variations in the Sect. Euthya are identified as new distribution records. Consequently, the medicinal plant distribution record of Paris L. in Shaanxi Province is complete. The natural resources are investigated, which have laid the foundation for further research, development and protection.

OBJECTIVETo examine the expressions of B7-H1 and its receptor programmed death-1 (PD-1) on circulating T cells and myeloid dendritic cells (mDCs) in patients with chronic hepatitis B virus (HBV) infection and to investigate the correlation between their expressions and their disease status.

METHODSThe expressions of B7-H1 and PD-1 on mDCs and T lymphocytes in 30 patients with chronic HBV infection and 28 healthy controls were analyzed by a fluorescence-activated cell sorter (FACS). Real time-polymerase chain reaction (RT-PCR) was used to measure the serum HBV DNA load.

RESULTSBoth B7-H1 and PD-1 were significantly upregulated on T cells and mDCs in those patients. Their expressions were positively correlated with the patients serum ALT levels and HBV DNA loads.

CONCLUSIONB7-H1 and PD-1 expressions in our patients with chronic hepatitis B are closely associated with their disease status.

Four children (two boys and two girls), aged from 3 years and 7 months to 5 years, had mild or moderate anemia, mild hepatosplenomegaly, jaundice (mainly an increase in indirect bilirubin), an increase in the percentages of reticulocytes and spherical erythrocytes in peripheral blood smear and an increase in erythrocyte osmotic brittleness. High-throughput sequencing found two novel mutations in the SLC4A1 gene, c.37G>A and c.340T>C, in case 1 and case 2 respectively, and these two mutations were predicted to be pathogenic by Mutation Taster. The Polyphen2 scores of these two mutations were 0.87 and 0.83 respectively, which suggested that these mutations were probably damaging. The SIFT scores of these two mutations were 0.008 and 0.09 respectively, suggesting that these mutations were probably damaging. No abnormality in this gene was found in their parents. Two reported heterozygous mutations in the ANK1 gene, c.830A>G and c.985G>C, were found in case 3 and case 4 respectively. Gene detection was not performed for the parents of case 3. The mother of case 4 was diagnosed with hereditary spherocytosis and had a heterozygous mutation of c.985G>C in the ANK1 gene. All four children were diagnosed with hereditary spherocytosis. Case 3 had a hemoglobin level of <80 g/L and underwent splenectomy at the age of 5 years and 6 months, and regular postoperative reexamination showed a hemoglobin level of >105 g/L. Hereditary spherocytosis is a hereditary hemolytic disease caused by abnormality in erythrocyte membrane protein, and gene detection helps to make a confirmed diagnosis.
