Objective To investigate the distribution status of coal-burning fluorosis (endemic fluorosis) areas in Luoyang and to provide scientifc evidence for making strategies in prevention and control. Methods In 2006, a household per village was chosen to carry the general survey so as of disease condition, living habits and housing structure among 941 coal-burning pollution fluorine sickness natural villages in Yanshi, Mengjin, Xin'an, Luanchuan counties and Geely area which were under the jurisdiction of Luoyang. In the general survey, the sampled village having a population of more than 500 person was considered as a major survey village, and water fluoride, 8 - 12 year-old child fluorine spot on tooth and the urinary fluoride were surveyed. Water fluoride and the child urinary fluoride determination used the fluoride ion selective electrode method, and the children's dental fluorosis used Dean method. Results The endemic fluorosis of Luoyang existed 742 in endemic fluomsis villages, compared with history, a decrease of 199 in number. Ninety-six point seven per cent( 142 543/147 419) of the households were consuming smoke-free coal. Households using intact kitchens accounted for 93.6%( 137 919/147 419). Of which 63.0%(86 889/137 919) of kitchens were mixed up with bedrooms. Total 125 060 people were using coal- fired furnace for heating, of which 87.8%(109 802/125 060) had smoke-free facilities, 12.2%(15 258/125 060) had none. Among 52 endemic villages with population of more than 500 people surveyed, a total of 183 water samples were collected, 2 had water fluoride exceeding 1.0 rag/L, the highest water fluoride being 1.04 rag/L, averaging 0.39 mg/L Sixteen villages had a prevalence rate of dental fluorosis for children less than 30.00%, accounting for 30.8% (16/52), 36 endemic villages the prevalence of dental fluorosis detection rate of more than 30.00%, accounting for 69.2%(36/52). Twenty-thrce villages had a dental fluorosis index greater than 0.6, severe dental fluorosis was not found. Real-time measurement of 1408 urine samples of children aged 8 - 12 showed that urine fluoride highest value 6.88 nag/L, the minimum value of 0.10 mg/L, geometric mean 1.10 mg/L. The prevalence rate of dental fluorosis for children was 36.06%. Conclusions In Luoyang city, numbers of coal-burning endemic fluorosis villages are less than before, children's dental fluorosis has significantly declined, however some people still use kitchens connecting with bedrooms and lack smoke-free facilities, they need to be educated to change lifestyle and improve furnace to reduce soot fluoride pollution.

OBJECTIVETo compare the effect,safety,and advantage of flexible fixation with paperboard and pad versus short leg plaster in treating the fifth metatarsal base fracture,and establish the standard of diagnosis and treatment of the fifth metatarsal base fractures in flexible fixation with paperboard and pad.

METHODSFrom June 2010 to March 2013,59 patients with the fifth metatarsal base fracture were treated with paperboard and pad fixation or short leg plaster. Patients were enrolled and divided into paperboard and pad treatment group (paperboard group) and short leg plaster treatment group (plaster group) randomly according to the random number table. In paperboard group,there were 29 cases including 9 males and 20 females with an average age of (51.79±11.40) years old; the average course of injury was (11.59±6.58) hours. In plaster group, there were 30 cases including 9 males and 21 females with an average age of (52.13+17.34) years old ;the average course of injury was (11.03±7.06) hours. According to whether the fracture line across the articular surface, in paperboard group there were 14 cases of type A,15 of type B; in plaster group,16 of type A, 14 of type B. According to the degree of dislocation,in paperboard group there were 16 cases of degree I ,13 of degree II ; in plaster group,20 were degree I ,10 were degree II. Fracture was restored according to the type in manual. Patients in paperboard group were treated with paperboard and pad, and patients in plaster group were treated with short leg plaster. Fracture was fixed for 4 to 6 weeks according to fracture healing. On the 2nd, 4th,6th, 8th week and 3rd, 6th month after fixation, patients were followed up, and the foot function score was used to evaluate the function of injured foot. X-ray of injured foot was taken on the 2nd, 4th, 6th and 8th week were used to assess fracture healing.

RESULTSAll patients got complete follow-up. The X-ray result showed that all fracture reached at clinical healing on the 8th week after fixation without skin ulcer,nonunion and displacement of fracture. From the 4th to 8th week after fixation, paperboard group had a higher X-ray score than plaster group, but the difference between two groups had no statistically significance. Repeated analysis result showed that there was interact at different time point and between groups,the difference had statistically significance (P<0.01). The foot function score showed that at all time point, paperboard group had a higher score than plaster group, and on the 2nd, 4th, and 6th week, it had statistically significant difference(P<0.01) between two groups. On the 6th months after fixation,the excellent and good rate of paperboard group was 93.10%, higher than that of plaster group, which was 86.67%. But it had no statistically difference(P=0.483) between two groups.

CONCLUSIONUsing paperboard and pad fixation to treat the fifth metatarsal base fracture has the advantage of simplicity operating,reliable fixation, satisfactory effects, easily obtainable material.

ObjectiveTo compare liver pathology changes of patients with Budd-Chiari syndrome (BCS) and intrahepatic portal hypertension (IPH) after portosystemic shunt surgery. MethodsFrom January 2010 to December 2011,liverbiopsy was taken during shunt surgery (9 BCS patients,4 IPH patients),and 6-9 months after surgery on follow-up.Collagen type Ⅳ ( Col Ⅳ ),procollagen m (PC Ⅲ ),matrix metalloproteinase (MMP-1),tissue inhibitors of metalloproteinase(TIMP-1) were tested using SABC (immuonohistochemistry) method,and HE staining to observe the morphology of liver tissue.Free portal vein pressure before and after shunt was measured. ResultsIn BCS group,Col Ⅳ,PC 1Ⅲ and TIMP-1expression downregulated after surgery (127 ±15) vs.(137 ±16),t =4.896,P-0.013; (115.2 ± 10.6) vs.(127.3±9.5),t=4.877,P=0.003; (119.2±11.3) vs.(131.2±l9.6),t=2.841,P=0.023.MMP-1expression did not change ( P ＞ 0.05 ),while MMP-1/TIMP-1was not significantly correlated with liver fibrosis (0.95 ±0.16) vs.(0.98 ±0.15),t =-0.710,P =0.504.In IPH group,the expression of Col Ⅳ,PCⅢ,MMP-1,and MMP-1/TIMP-1did not change significantly after surgery (P ＞0.05).Compared with that in IPH group the expression of PC Ⅲ,Col Ⅳ and TIMP-1downregulated significantly in BCSgroup (127±15) vs.(150 ±12),U=3.000,P=0.038; (115.2 ±10.6) vs.(128.1±2.8),U=2.000,P=0.023; (119.2 ± 11.3) vs.(131.4 ±2.5),U=3.000,P =0.038.By HE staining in BCS group there was significant intrahepatic congestion which alleviated after surgery.While in PHT group liver pathology did not change significantly after surgery.FPP in BCS and IPH patients significantly decreased after shunt surgery (25 ±8) vs.(41±8) cmH20,t=17.816,P=0.000;(31±8) vs.(45 ±9) cmH20,t =5.745,P =0.010 ). Drop of FPP of BCS group plays a key role in reversal of liver fibrosis.ConclusionsIn BCS group liver pathology improved after shunt surgery probably by removing the intrahepatic obstruction,but in IPH group liver pathology remained unchanged after shunt.

Objective To discuss the role of assistance of intraoperative uitrasonography in ret-roperitoneal laparoscopic nephron-sparing surgery for renal tumors. Methods The intraoperative laparoscopic ultrasonography was applied in retroperitoneal nephron-sparing surgery for 20 patients, of whom 11 were men and 9 were women. The average age was 53(range 33 to 73) years. There were 12 patients with renal cell carcinoma and the mean tumor size was 2.9(range 1.4 to 4.6)cm in diame-ter. All of them were staged as T1 N0 M0. Seven patients had angiomyolipoma and the mean tumor size was 4.5(range 1.8 to 8.0)cm in diameter and 1 patient had a 3.1 cm oncocytoma in diameter. The ul-trasonography was used to locate the tumor, observe the bloodstream and detect whether there were small satellite tumors. The surgical time, time of renal artery occlusion and operative effect were ob-served. Results Laparoscopic surgery was successful in all cases without conversion to open surger-y. Mean operative time was 115 (range 85 to 270) min, mean time of renal artery occlusion was 28 (range 22 to 50) min. During the mean followup of 16(range 4 to 30) months, no patients with renal cell carcinoma had local or port site recurrence or metastatic disease. Conclusion In retroperitoneal laparoscopic nephron-sparing surgery, the intraoperative uhrasonography is helpful to locate the tumor in the surgery, to estimate whether the renal artery is occluded completely and to excise the tumor pre-cisely.

β-Amyrin synthase (β-AS) genes of Glycyrrhiza uralensis from 6 different regions were analyzed by PCR-SSCP and sequenced, then the correlationship between β-AS SNP and regions of Glycyrrhiza uralensis were determined. According to the 1 coding single nucleotide polymorphism on the first exon of β-AS gene at 94 bp site, Glycyrrhiza uralensis could be divided into 3 genotypes. In these genotypes, the percentage of 94A type in genuine regions was much higher, and it had significant differences with the percentage in non-genuine regions (P < 0.001). The results of the experiment proved that different β-AS genotypes at 94 bp site from different regions may be one of the important reasons to result in the genuineness of Glycyrrhiza uralensis.
