Objective To analyze the epidemiological characteristics for new detecting cases of leprosy in 2012, in Yunnan Province, and provide clue and foundation for prevention and treatment in leprosy control. Methods The date of diagnosed leprosy patients in 2012 in Yunnan Province were collected and analyzed by disease reporting information system. Results 230 new cases were founded in 2012, and the discovery rate was 0.50/100 000. 4.35% of new cases were children, 64.35% of new cases were MB and 19.57% had grade 2 disability. 17 recurrent cases were founded in 2012,and 6 of them had received MDT. By the end of 2012, there were still 1084 present case in Yunnan Province,the prevalence rate was 0.24/10 000,and 485 of them need MDT. Conclusion The prevalence of leprosy was decreased,and the prevalence varies a lot in different regions. Honghe and Wenshan are still the focus regions. Leprosy is still a serious public health and social problem in Yunnan Province. In order to reduce the burden of leprosy and eliminate the leprosy danger, long-term financing investment and prevention are still needed.

OBJECTIVETo research the influence of gilt to the retention of the complete metal crown.

METHODSSixty Ni-Cr alloy complete metal crown were divided into three groups, control group (common Ni-Cr alloy complete metal crown), whole gold-plating group (whole gilding on the tissue surface of the inner Ni-Cr alloy complete metal crown), partial gold-plating group (gilding on the tissue surface of 1/3 cervical inner Ni-Cr alloy complete metal crown). The retention force of complete metal crown was measured by tensile force/pressure ergograph.

RESULTSThe retention force of control group, partial gold-plating group, whole gold-plating group were (657 +/- 151) N, (632 +/- 139) N, (569 +/- 103) N, respectively. There were significant differences between control group and whole gold-plating group, whole gold-plating group and partial gold-plating group (P < 0.05). There was no significant difference between control group and partial gold-plating group (P > 0.05).

CONCLUSIONThe force of retention would decrease after gilding on the tissue surface of the inner Ni-Cr alloy complete metal crown, but have no influence to normal retention requirement of complete crown. Although the retention of partial gold-plating complete metal crown had somewhat decrease, it could be ignored.

OBJECTIVETo evaluate the clinic effects of alginate impression and agar/alginate combined impression.

METHODS237 patients of fixed partial denture were collected and divided into group A and group B. Group A was taken impression by aglinate impression, including 81 patients (207 abutments). Group B was taken impression by agar/alginate combined impression, include 156 patients (392 abutments). The impressions were observed by megaloscope, and the number of abutment, the types and number of defect were recorded.

RESULTSIn the aglinate impressions, 57.0 percent of abutment had some defect. But in the agar/alginate combined impressions, 36.0 percent of abutment had some defect. There were significant difference between group A and group B in the abutment, air bubbles in cervical margin, unsharpness of the gingival sulcus and shoulders (P<0.05). There were no significant difference between group A and group B in the split and defect of the impressions on the cervical margin.

CONCLUSIONThere were less defects in the agar/alginate combined impression than in the alginate impression.

OBJECTIVETo investigate the expression and clinical significance of Ephrin-A1 mRNA and protein expression level in hepatocellular carcinoma.

METHODSReverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry technique were used to detect the expression of the Ephrin-A1 mRNA and protein of 40 cases of hepatocellular carcinoma and their corresponding para-cancerous tissues and 10 cases of normal liver tissues. The relationships with its clinical pathology characters were analyzed.

RESULTSThe mRNA of Ephrin-A1 was expressed in all of the 40 cases of hepatocellular carcinoma and their corresponding para-cancerous tissues and 10 cases of normal liver tissues. Semiquantitative analysis showed that the mRNA expression level of Ephrin-A1 in hepatocellular carcinoma (0.5413 +/- 0.1527) was greater than that in corresponding para-cancerous tissues (0.3895 +/- 0.0549, P < 0.05) and normal liver tissues (0.3770 +/- 0.1055, P < 0.05); but between corresponding para-cancerous tissues (0.3895 +/- 0.0549) and normal liver tissues (0.3770 +/- 0.1055), the mRNA expression level had no significant difference (P > 0.05). The positive rates of Ephrin-A1 protein were 20% (2/10) in normal tissues, 35% (14/40) in para-cancerous tissues and 62% (25/40) in hepatocellular carcinoma tissues, respectively; the protein expression level of Ephrin-A1 was gradually rising (chi(2) = 14.762, P < 0.05). The overexpression of Ephrin-A1 protein was correlated with histological differentiation, tumor thrombi in portal vein and lymph node metastasis (P < 0.05).

CONCLUSIONSThe overexpression of Ephrin-A1 protein is correlated with histological differentiation, the lymph node metastasis and tumor thrombi in portal vein. It indicates that Ephrin-A1 may play an important role in the malignancy transformation, invasion progression and metastasis of hepatocellular carcinoma.

OBJECTIVETo introduce the clinical experience in transplantation of the anterolateral femoral skin flap.

METHODSA total of 625 anterolateral femoral skin flaps in 600 patients were transplanted from 1988 to 2003. The retrospective analysis was carried out in all the cases as to the flap pedicle, the vascular variations, the surgical procedures and modifications, and the adaptation for a cutaneous-branch-absent flap.

RESULTSThe 625 flaps were transferred except 7 cancelled in the operation. Postoperatively, 17 cases encountered vascular complications, 10 of which survived completely with successful vessel exploration, 3 cases had partial necrosis, and 4 cases had complete necrosis. The survival rate was 97.8%. 545 flaps were pedicled with the descending branch or lateral branches; 45 flaps with the transverse branch or the high-site anterolateral cutaneous artery, 10 cases with the descending-transverse branch, 18 cases with other vessels. 7 cases were found cutaneous-branch-absent. The vessel variation rate of the flap was 4.06%.

CONCLUSIONSThe anterolateral femoral skin flap has less variation of its pedicle and high success rate of operation. It is an ideal choice for repair of soft tissue defects in the extremities.

Objective To investigate the supply of iodized salt in non-excessive iodine counties and iodine-free salt in excessive iodine counties at household level in Hebei province so as to provide a basis for the prevention and control of iodine deficiency disorders(IDD). Methods According to the national project of IDD surveillance,the county was taken as the elementary sampling unit. The towns and villages were selected by systematic and random sampling in every county and households were chosen by random sampling to collect their edible salt in Hebei province in 2008. The salt iodine content in non-and excessive iodine regions was detected by direct titrition method and semiquantitative method respectively. Results all 48 448 salt samples were collected from 167 non-excessive iodine counties. Weighed by the population of counties,the rate of non-iodized salt was 4.73%. Iodized salt accounted for 95.27%,out of which,96.13% were qualified and the consuming rate of qualified iodized salt was 91.96%. Eighty point eighty three percent(135/167) of the counties covered by iodized salt above 95%,92.81% (155/167) passing rate of iodized salt above 90% and 82.04 (137/167) consuming rate of qualified iodized salt. All 1466 salt samples were collected in 5 counties with excessive water iodine content and the coverage rate of iodine-free salt was 93.25%(1367/1466). Conclusions In a nutshell,the national targets for preliminary elimination of IDD have been achieved in regions of non-excessive iodine of Hebei province. Nevertheless,the coverage rate of iodized salt and qualified iodize salt rate in some counties are still below the national standard. Therefore the prevention and control of IDD need to be strengthened. The supply of iodized salt in excessive iodine regions should be timely stopped.

Objective To understand the status of drinking-water-borne endemic fluorosis and the effect of preventive measure in Hebei province, so as to provide a basis to prevent and cure the disease. Methods Thirtyeight affected counties(cities, districts) with drinking-water-borne endemic fluorosis were sampled by random sampling in Hebei in 2009. All affected villages in every county were divided into mild, moderate and severe endemic fluorosis areas and a village was randomly selected from each category of the area to carry out the monitoring of endemic fluorosis. Dental fluorosis of children aged 8 - 12 were examined and 6 copies of urine samples were randomly collected in each age group in the above-mentioned villages. Clinical skeletal fluorosis was diagnosed among adults aged 16 and over and 20 copies of urine samples were tested for fluorosis in every village.Results A total of 112 affected villages were investigated, among which the drinking water quality of 66 villages were improved and 46 villages were not improved. A total of 236 copies of water samples from the 66 villages were measured and the fluoride content ranged from 0.1 to 4.3 mg/L, among which 20 copies of water samples exceeded the fluorine standard of 1.2 mg/L, accounting for 33.3%. A total of 230 copies of water samples were collected in the 46 villages and the fluoride content ranged from 0.2 to 4.6 mg/L, among which 76.1% (35/46) of the water samples exceeded the fluorine standard of 1.2 mg/L. A total of 5169 children aged 8 - 12 were examined of dental fluorosis, the dental fluorosis rate was 36.43%(1883/5169) and the dental fluorosis index was 0.81. A sum of 71 497 adults aged over 16 years were examined, and the rate of skeletal fluorosis was 4.81%(3438/71 497), moderate or severe clinical detection rate of skeletal fluorosis was 1.56%( 1114/71 497). A total of 2876 copies of children urine samples and 2021 copies of adult urine samples were tested and the geometric mean of fluoride content was 2.30,3.32 mg/L, respectively. Conclusions The prevalence of dental fluorosis of children in the areas with improved water is less than 30% and the rate of dental fluorosis and skeletal fluorosis decline gradually with time.The rate of dental fluorosis and skeletal fluorosis increases with the increase of water fluoride in the water quality not improved areas. The endemic fluorosis is still comparatively serious in Hebei. The progress of improving water quality in the areas with endemic fluorosis should be accelerated and the acceptability of improved water should be enhanced.
