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.

Background and purpose:Intensity-modulated radiotherapy(IMRT) can significantly improve the dosimetric distribution of both the target and organs at risk compared to tangential irradiation for whole breast. However,its optimized methods remain different and conflicting for many radiotherapy institutions.In order to achieve the optimized planning of IMRT for the irradiation of intact breast,we investigated different optimizing methods in three dimensional radiotherapy planning system.Methods:Ten patients with early-stage breast cancer after breast conserving surgery were eligible for the study.Two kinds of plans were performed on each patient in three-dimensional treatment planning system,inverse planning IMRT and forward planning IMRT which included 3 different optimizing methods as manual optimizing(MO),multiple points optimizing(PO) and automated inverse optimizing(AO).Various parameters were used to evaluate the efficacy of different IMRT plans.All plans were compared using dose volume histograms(DVH) for the planning target volume(PTV) and organs at risk(OARs).Results:For MO,PO,AO forward plans and inverse plans,median number of segments were 5,5.5,5 and 20 respectively,and mean total MU were 225.8, 228.4,226.4 and 345.8 MU,respectively.Comparing the different forward planning optimizations,the best target coverage and dose homogeneity of PTV was observed in AO plans(P(?)0.01),and PO and AO plans showed a better reduction of OARs exposure compared with MO plans(P(?)0.05).A further improvement of dose homogeneity in the PTV and better sparing of OARs was achieved using inverse planning(P(?)0.05).Conclusion:Forward planning IMRT with AO optimization for intact breast irradiation could provide both efficacy and dosimetric advantages better than others.The inverse IMRT plan showed more potential in improving the dosimetric outcomes.However,further studies are required for inverse optimizing plans.
