Objective To evaluate the differences of the lower extremity atherosclerosis between patients with and without type 2 diabetes using dual-source CT angiography.Methods Dual-source CT angiography of lower extremity was performed in 87 patients with (n=30)or without (n= 57 )diabetes.Extent of luminal stenosis,and the type,distribution and range of the plaques were compared.Results 342 plaques in 540 segments (63.3%)in diabetic patients,and 500 plaques in 1 026 segments (48.7%)in non-diabetic ones were detected respectively.Compared with non-diabetic patients,the diabetic ones had a higher overall incidence of plaques (P <0.05).Calcified plaques were the most common in both kinds of patients,and the incidence of mixed plaques was high-er in diabetic patients than that in non-diabetic ones (35.6 % vs.28.4%,P <0.05).Light to moderate stenosis occurred in most diabetic patients,and fewer occlusion was found compared with non-diabetic ones (9.1% vs.1 7.0%,P <0.05).The most common sites of the plaques in diabetic patients were located at distal small arteries below the knee.However,those were located at proximal arteries above the knee for non-diabetic ones.The involvement of atherosclerosis in diabetic patients was more diffused,and the de-gree of Ⅳ (75%-100%)was higher than that in non-diabetic ones (P <0.05).Conclusion Atherosclerosis in lower extremity on dual-source CT angiography is very common in diabetic patients with multi-segmental,diffused,non-obstructive involvement of dis-tal small arteries below the knee.

Objective To evaluate the role of CT in the diagnosis of the primary carcinoma of the duodenum.Methods CT findings of 15 patients with primary carcinoma of the duodenum(12 adenocarcinoma,3 carcinoid)underwent surgical treatment or biopsy were reviewed.Results 9/12 of adenocarcinomas were shown as local soft tissues masses;6/12 of adenocarcinomas manifested as ductal wall irregular or circular thickening;3/12 of adenocarcinomas were shown as local soft tissues masses accompanied with deformation and constriction of duodenum.Cholangiectasis,metastasis of retroperitoneal lymph nodes and liver were also founded.CT cannot difference adenocarcinoma with carcinoid.After enhancement,the masses were manifested as mild or intermediate enhancement in the early stage and they did not show obviously enhancement in the delay or portal stage.Conclusion CT play an important role in both the localization and qualitative diagnosis of the primary carcinoma of duodenum,but it is difficult to difference adenocarcinoma with carcinoid.

AIM: To identify an unknown peak in Guanxinning Injection(Radix et Rhizome Salviae Miltiorrhizae,Rhizoma Chuanxiong) chromatographic fingerprint. METHODS: The elution(44-46 min) separated and collected by HPLC was analyzed by GC-MS and HPLC-PDA-MS-MS. RESULTS: The unknown peak was corresponding to senkyunolidel I. CONCLUSION: It is quick method to identify the reported chemical in herbal medicine based on a small quantity of sample by GC-MS and HPLC-PDA-MS-MS.

Objective To investigate the relationship between arsenic in drinking water and skin lesions in endemic arsenism area in Shanyin County of Shanxi Province,in order to provide epidemiologic data for further arsenism research.Methods One hundred and eighty-nine endemic arsenism patients and 59 controls were randomly selected in 17 endemic amenism countries in Shanyin County of Shanxi Province.The content of arsenic in drinking water which wa8 collected indoom was half-quantitatively screened by a kit made by Chinese Center for Disease Control and Prevention,then quantitatively determined by HPLC-ICP-MS.Patients of endemic arsenism were diagnosed by "The Standard of Diagnosis for Endemic Amenism"(WS/T 211-2001).Results There were 64.9% (87/134)samples above the arsenic level(50μg/L)of drinking water and the median value of arsenic in drinking water was 91.43 μg/L in 134 water samples.The OR(95%CI)value between arsenic in drinking water and hyperkeratosis,hyperpigmentation,depigmentation was 2.46(1.22-4.94),3.34(1.50～7.44)and 2.86(1.50-5.46),respectively.The prevalence of hyperkeratosis,hyperpigmentation and depigmentation increased,as the arsenic in drinking water increased(≤10,≤50,≤200,＞200μg/L),especially in＞200μg/L group(OR=6.15,13.96,11.41,P＜0.05).The arsenic level in drinking water of Ⅲ degree of depigmentation patients(318.300μg/L)was higher(P＜0.05)than that of 0,Ⅰ and Ⅱ degree groups(86.670,131.800,1 10.590μg/L,P＜0.05).Conclusions Shanyin County is a medial arsenic pollution area. Arsenic in drinking water is considered as a risk factor of skin lesion. The degree of skin lesions increased,as the arsenic in drinking water increased.

Objective To investigate the daily total fluoride intake in relating to the prevalence of skeletal fluorosis in two villages in Jiangsu Province,in order to provide the scientific evidences for the control and prevention of endemic fluorosis.Methods Adults sampled from a high-fluoride Village,Wamiao,and a low-fluoride Village,Xinhuai,were surveyed in this study according to the fluoride concentration in their household shallow well.The average daily total fluoride intake from difierent sources and the skeletal fluorosis were investigated in each subject.Then the subjects from two villages were allocated into five subgroups(＜2.00,2.00～,3.00～,4.00～,≥5.00 mg/d),the relation fluoride intake and prevalence of osteofluorosis was analyzed.Results The prevalence of skeletal fluorosis in Wamiao Village was 31.06%(41/132),but no skeletal fluorosis case(0/35)was found in Xinhuai Village.According to the daily total fluoride intake,subjects with higher daily total fluoride intake tended to associated with a higher prevalence of skeletal fluorosis in a significant dose-response relationship(regression equation:y=2.624-6.855x+3.424x2:r=0.997).The benchmark dose lower limitation of daily total fluoride intake with 95% confidencewas 2.50 mg/d calculated according to this dose-response relationship,the reference dose(RfD)was 2.50 mg/d.In Wamiao Village a significant difference was also found between daily total fluoride intake in 41 subjects[(5.09±1.20)mg/d]with X-ray detectable skeletal fluorosis and in 91 subjects[(3.08±1.12)mg/d]without X-ray detectable skeletal fluorosis(t=-9.32,P＜0.01).Conclusions These findings indicate that the daily total fluoride intake has a significant dose-response relationship with the prevalence of skeletal fluorosis in an endemic fluorosis area associated with high-fluoride drinking water;and the RfD in this study was lower than that in the national standard of"Chinese hygienic standard for daily total fluoride intake(WS/T 87-1996)"(3.50 mg/d).

Objective To evaluate the prognosis and fertility outcomes of patients with early stage of cervical cancer treated by vaginal radical trachelectomy ( VRT ) in combination with laparoscopic pelvic lymphadenectomy.Methods The surgical data , disease recurrences and fertility outcomes were analyzed retrospectively for 51 patients who received VRT in Peking Union Medical College Hospital from Dec.2003 to Nov.2013.Results Forty-eight patients succeeded in preserving fertility.The median age was 29 years.International Federation of Gynecology and Obstetrics ( FIGO ) stage: 5 cases Ⅰa1 with lymph vascular space invasion (LVSI),4 cases Ⅰa2 and 39 cases in stage Ⅰb1.Tumor size: 20 cases with no visible lesion, 20 cases with tumor size ≤2 cm, 8 cases with tumor size >2 cm.Histological type:42 cases with squamous carcinoma , 6 cases with adenocarcinoma or adeno-squamous carcinoma.The mean excised cervical length and parametrial width was ( 2.6 ±0.6 ) cm and ( 1.9 ±0.5 ) cm, respectively.Six recurrences ( 12%) were observed after following up for a mean duration of ( 35 ±21 ) months.The recurrent rate in patients with tumor size >2 cm was 3/8, which was significantly higher than that of the
patients with tumor size ≤2 cm (8%, 3/40;P<0.01).Of the 35 patients who desired to conceive after the surgery, 13 women had 17 pregnancies and the pregnant rate was 37% (13/35).Nine women obtained 10 healthy live birth babies.The fertility rate was 26%( 9/35 ).Conclusions VRT in combination with laparoscopic pelvic lymphadenectomy could preserve the fertility of patients with early stage of cervical cancer with acceptable oncologic and fertility outcomes.Tumor size ≤2 cm should be emphasized as the indication of VRT in considering of the higher recurrent rate in patients with tumor size >2 cm.
