Objective To investigate the clinical treatment principles of asymptomatic cholecystolithiasis. Methods 136 cases of asymptomatic cholecystolithiasis, found on health check up, were randomly divided into two groups :(1) Preventive cholecystectomy group,66 cases;(2)therapeutic cholecystectomy group,70 cases. The data of postoperative pathologic examination, complications and degree of operative difficulty between the two groups were compared. Results The postoperative pathologic examination, complications and degree of operative difficulty between the two groups were significantly different(P

Objective To investigate the clinical features and prognosis of replantation of fingertips distal to the middle nail.Methods Between August 2001 and August 2005,16 fingertips amputated in the Ishikawa zoneⅠwere replanted.We anastomosed only the digital arteries,and adopted postoperative bloodletting.Results Fourteen fingertips survived,and two failed.The survival rate was 87.5%.Of the 14 successfully replanted fin- gertips,12 were followed up from 3 to 12 months.The length and appearance of the fingertips recovered and good joint motion were maintained.Their two-point discriminations ranged from 3 to 6 mm.Conclusion Fingertip replantation is an optimal treatment for fingertip amputation distal to the middle nail to regain satisfactory appearance and function of the digits with a high survival rate,but severe crush injury to the amputated part and high cost should be taken into consideration.

Objective To investigate the distribution of water fluoride and the present status of water-improving defuoridation projects in the endmie fluorosis areas in Gansu Province in 2006. Methods The content of fluoride in drinking water in 18 endemic disease counties was screened, and the defluoridation projects built after the 1980s were supervised and inspected. The content of fluoride in drinking water was assessed by F-ion selective electrode. Results Fluoride content was determined in water of 6260 sources in 1252 fluorosis villages in 18 counties, with 63.50% (3975/6260)≤1.0 mg/L and 36.50%(2285/6260)>1.0 mg/L. Nine hundred and ninty-seven water-improving and clefluoridation projects had been investigated in 16 counties, among which 95.49% (952/997) were function well, and projects intermittently running or abandoned respectively accounted for 3.11% (31/997) and 1.40%(14/997). Nine hundred and eighty-three sources of water treated by the water-improving and defluoridation projects had been determined for fluoride content, it turned out that 91.76% (902/983) were within the standard, only 8.24% (81/983) were not; as for outlet and leftover water of 934 water-improving and defluoridatian projects determined for water fluoride content, qualified projects accounted for 92.08% (860/934) and 91.97%(859/934), leaving 7.92%(74/934) and 8.03%(75/934) disqualified, respectively. Water-improving and defluoridation projects mostly relied on drilling a well in gaining under-ground water or collecting surface-ground water, so under-ground water and surface-ground water are the majority. Conclusions Water fluoride content exceeds the standard in some of the villages. A few projects do not function well. Fluorosis damage still exists in Gansu Province, therefore countermeasures for endemic fluorosis must be carried out as promptly as possible and surveillance on water-improving and defluoridation projects must be strengthened and managed.

Objective To study the liver damage induced by platelet activating factor (PAF) and the protective effects of the PAF antagonist WEB2170. Methods Experiments in vivo: after the administration of PAF to induce liver damage in rats, serum levels of aspartate transaminase (AST), alanine transaminase (ALT), lactic dehydrogenase (LDH) and tissue malonyldialdehyde (MDA) were determined by biochemical method, the succinate dehydrogenase (SDH) activity in mitochondrion was assessed by histochemical method, and the morphologic changes in hepatic structure were observed. In the treatment group, WEB2170 was used for intervention. Experiments in vitro: the fluidity of cellular velum of liver cells was detected with DPH probe, and the effect of TNF and MDA produced by Kupffer cells cultured by PAF stimulation was observed. Results PAF increased the expression of serum AST, ALT, LDH and tissue MDA (P

Objective To study the esthetic indexes of soft tissue profile in lateral face in Anhui youths with normal occlusion. Methods The study was carried out by taking the cephalometric photographs in the 102 Anhui youths with normal occlusion. The data of measurement were got from the photographs by image database and analysis system (IDAS) software, and statistically evaluated by SPSS software. Some specially selected items were analysed again by Fisher's discriminant method. Results Seven items, i.e. Li Ns Pos, Ls Ns Pos, Ls B, Li B, Sn H, Bs Li FH and Z angle, were chosen as esthetic indexes of facial profile, and the discriminant functional formula was established. Conclusion Combination of all the above 7 items contribute to the beauty of facial profile.
