As an important indicator of total hip arthroplasty (THA) the rate and degree of offset reconstruction play an important role in improving the prognosis and life quality of patients. The reconstruction of femoral offset is closely related to reserved length of calcar femorale, the head and neck length of prosthesis, angle degree of neck shaft and whether lower limb is isometric. Reconstruction strategy includes making a meticulous and standard measurement before the surgery, predicting the reserved length of calcar femorale, selecting a prosthesis with approximate anatomical neck-shaft angle and reconstructing offset by adjusting the head and neck length of the prosthetic during the operation. The aim of this article was to introduce the research progress and influence of offset on hip function, prosthetic wear and postoperative complications such as pain, limp and unequal leg length, and to discuss the reconstruction strategy.

Objective To evaluate the validity of Community Extremity Disability Assessment Schedule (CEDA) in community rehabilitation. Methods 313 patients with hemiplegia after stroke were divided into rehabilitation group and control group. The rehabilitation group received community-based rehabilitation (CBR) for 3 months, and was assessed with Community Extremity Disability Assessment Schedule before and 1 month, 2 months and 3 months after rehabilitation respectively. And it was compared with Fugl-Meyer Assessment (FMA). The control group received the same evaluation only. Results The scores of CEDA and FMA improved more in the rehabilitation group than in the control group 2 months after rehabilitation (P<0.01). The score of CEDA positively correlated with the FMA (r=0.643, P<0.01). Conclusion CEDA can be used to evaluate the efficacy of community rehabilitation.

Objective To study local people's habits and customs concerning the prevention of dental fluorosis in an indoor coal-combustion-type fluorosis area of Zhaotong city Yunnan province, and to provide reference value for monitoring and control of the disease. Methods In 2008, 600 people of a 12-year-old group (400 people) and a 35 - 44-year-old group(200 people) were examined for dental fluorosis and oral health status in an indoor coal-combustion-type fluorosis area of Zhaotong. A questionnaire survey of 120 students and 60 adults was carried out on their habits and customs, stove changing status, knowledge of prevention of dental fluorosis, social psychology status, oral health behavior and their need for medical treatment. Results The total prevalence of dental fluorosis was 91.0% (546/600), dental fluorosis index was 2.58. The total prevalence of dental fluorosis of 12-year-old group was 86.5%(346/400), and dental fluorosis index was 2.12. The total prevalence of dental fluorosis of rural student was 90.5% (181/200), which was obviously higher in the rural group than the urban group [82.5% (165/200), χ2 = 5.48, P < 0.05]. The total prevalence of dental fluorosis of 35-44-year-old group was 100% (200/200), which was obviously higher than that of the 12-year-old group(χ2 = 29.67, P < 0.01). The rates of using coal, baking of food, changing stoves were 66.7% (60/90), 14.4% (13/90),57.8% (52/90), respectively, and these values of the urban were much lower than those of the rural[95.6%(86/90) ,31.1%(28/90) ,76.7%(69/90),χ2 = 24.51,7.11,7.29, all P < 0.01]. Only 23.3% (42/180) of people surveied had the knowledge of prevention of dental fluorosis, and the rate in the adult group[56.7% (34/60)]was higher than that of the student group [6.7% (8/120), χ2 = 55.9, P < 0.01]. The same rate in the urban student group was 0(0/60), and the rural student group was 13.3%(8/60), there was a significant difference between them(χ2 = 5.66, P < 0.05). Seventy-three point nine per cent( 133/180) of these people thought dental fluorosis had significant effect on their life, 91.1%(164/180) of these 'people wished to be treated. Eighty-four point four per cent( 152/180) of the people had a habit of toothbrushing,and 50.7% (77/152) of these people were still using toothpaste containing fluorine. Conclusions Zhaotong is a serious indoor coal-combustion-type fluorosis area. Enhancing health education to local people especially to students, and changing people's unhealthy habits and customs are keies to control the prevalence of indoor coal-combustion-type dental fluorosis.

The binding of pefloxacin mesylate (PFLX) to bovine lactoferrin (BLf) and human serum albumin (HSA) in dilute aqueous solution was studied using fluorescence spectra and absorbance spectra. The binding constant K and the binding sites n were obtained by fluorescence quenching method. The binding distance r and energy-transfer efficiency E between pefloxacin mesylate and bovine lactoferrin as well as human serum albumin were also obtained according to the mechanism of Förster-type dipole-dipole nonradiative energy-transfer. The effects of pefloxacin mesylate on the conformations of bovine lactoferrin and human serum albumin were also analyzed using synchronous fluorescence spectroscopy.

Objective To investigate the effects of limited resuscitation on hepatic ischernia-reperfusion in-jury in rots with hemorrhagic shock. Method Uncontrolled hemorrhagic shock was induced in 54 rats by transect-ing the middle branch of the splenic artery to produce standardized massive splenic injury. Resuscitation started when the mean arterial pressure (MAP) reached 40 mmHg. The rats were randomly divided (n = 9per group) in-to sham-operated group (SS), or one of five treatment groups in which infusion of Ringer' s solution was continually administrated to maintain MAP at 40 (RS40), 50 (RS50), 60 (RS60), 80 (RS80) or 100 mmHg (RS100) for 45 minutes (T45 point). After the bleeding was controlled, resuscitation was continued with Ringer's solution and whole blood (2:1) to increase the MAP to 100 mmHg for 120 minutes (T165 point), which was followed by obser-vation for 240 minutes (T405 point). All animals were observed for 240 minutes or until death. Blood specimens were collected at TO, T45, T165 and T405 for determination of blood lactate levels. At the end of the experiment,a small amount of hepatic tissue was collected to measure tissue blood perfusion, total antioxidative capacity (TAOC), Na+K+ ATPase activity and malondialdehyde (MDA) levels. Results At T405, the blood lactate lev-els in the RS80 and RS100 groups [(3.60±0.68) and (3.84 ± 1.09) mmol/L, respectively] were significantly higher than those in the SS, RS40, RS50 and RS60 groups [(2.00±0.66),(2.74±1.45),(2.43 +0.94) and (2.07±0.95) mmol/L, respectively;all:P < 0.05]. The MDA levels were significantly higher in the RS80 and RS100[(7.32±0.31) and (7.71±0.23) nmol/mg,respectively] than those in the SS, RS40, RS50 and RS60 groups[(4.95±0.80),(6.14±0.94),(6.42±0.48) and (6.84±0.36) nmol/mg, respeetively;all: P <0.05]. The Na+ K+ ATPase and TAOC levels were significantly lower in all of the RS groups than those in the SS group (all: P < 0.05), and those in the RS80 and RS100 groups was significantly lower than those in the RS40,RS50 and RS60 groups (all: P <0.05). Blood perfusion in the RS80 and RS100 groups was significantly lower than that in the other groups (all: P < 0.05). Conclusions If hemorrhage is uncontrolled, limited resuscitation appears to balance the needs for organ perfusion, improve the microcircttlation and decrease lactate levels. Fur-thermore, limited resuscitation could decrease ischemia-reperfusion injury in liver tissue.
