OBJECTIVETo investigate the clinical effects of double-plating internal fixation for the treatment of medial tibial plateau fractures with fracture-dislocation type through combined anterior and inverted "L" posteromedial knee approaches.
METHODSFrom February 2010 to September 2013, 17 patients with medial tibial plateau fractures with fracture-dislocation type were treated by double-plating internal fixation at our department. Anterior knee approach was adopted for medial mass reduction and fixation,while the inverted "L" posteromedial approach was used for posteromedial mass. There were 11 males and 6 females, with an average age of 42 years old (ranged, 21 to 65 years old). The efficacy were investigated by comparing pre- and post-operative radiographic data, and by evaluating clinical symptoms using the HSS score system.
RESULTSAll the patients were followed with a mean time of 18 months (ranged, 11 to 25 months). The tibial-plateau varus angle immediately after operation and at the latest follow-up were respectively (87.8 ± 4.2)° and (88.2 ± 4.6)°, and there was no statistical difference (P = 0.458). The posterior slope angle immediately after operation and at the latest follow-up were respectively (10.1 ± 3.7)° and (10.3 ± 4.1)°, and there was no statistical difference (P = 0.512). The knee joint HSS score was 86.7 ± 6.1. No patient had complications such as infection, skin necrosis, internal fixation loosening or loss of fracture reduction.
CONCLUSIONDoubl-plating internal fixation through combined approaches is an ideal operation method for medial tibial plateau fractures with fracture-dislocation type, because it can provide clear surgical field, satisfactory reduction, reliable fixation, and chance for early functional exercise.

Background The key premise of genetic research and treatment is to select the desired gene vector,ultrasound microbubbles as a new type of gene vector can safe,fast and effectively enhance the gene transfection and expression by reversibility increasing the permeability of cells. Objective This study was to observe the effects of ciliary neurotrophic factor(CNTF)gene mediated by ultrasound microbubbles intraocular transfer on visual function and retinal ganglion cell(BGCs)after optic nerve injury. Methods Fifty-five adult Sprague-Dawley(SD)rats were divided into 6 groups randomly,including normal control group(n=5),sham injury group(n=10),simple injury group(n=10),naked plasmid group(n=10),plasmid+ultrasonic irradiation group(n=10)and ultrasound microbubbles group(n=10).The model of optic nerve injury Was made by forceps clip on the fight optic nerve.and the corresponding intervene was performed in different groups.Flash visual evoked potential(F

Background The main mechanism of diabetic retinopathy (DR) is the formation of retinal neovascularization. Vascular endothelial growth factors (VEGF) is primarily factor for DR. Objective The goal of this study was to investigate the effects of angelicae sinensis decoction for supplementing blood ( ASD), a kind of traditional prescription of Chinese herbal medicine, on vascular endothelial growth factor (VEGF) level in vitreous and serum of STZ-induced type 2 diabetes mellitus. Methods Thirty-four SPF male SD rats were fed using high fat diet for 8 weeks and then the streptozocin of 25 mg/kg was intraperitoneally injected to create the type 2 diabetic models. ASD (3.6 g/kg) and 10 mg/kg Gli of 5 mi were administered intragastrically from the 4th day of high fat die though 8 weeks respectively. Other 10 matched rats were used as normal control group. The body weight, blood glucose level ,triglycerides (TG) and high density lipoprotein (HDL) were detected in 4 and 8 weeks after usage of drug. The vitreous and serum samples were obtained in the 8 th weeks for the VEGF detection by enzyme-linked immunosorbent assay (ELISA). This experiment comlied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission. Results The body weight and HDL in DM group were significantly lower than those of normal control group in 4 or 8 weeks ( P<0. 01 ), but in ASD and Gli groups ,the body weight and HDL were higher than those of the DM group (P<0. 05 ). the blood glucose level and TG were elevated in DM group compared with normal control group (P<0. 01 ), but those in ASD group and Gli group were decreased in comparison with DM group ( P<0.05 ). EIISA revealed that no significant differences were found in VEGF levels between normal control group and ASD group or Gli group (P>0. 05 ), but in DM group, the serum VEGF level (147.65±4. 55 ng/L) was reduced and vitreous VEGF level (673.45± 100. 85 ng/L) was raised,showing the considerable differences (P< 0.05 ). No any correlation was found between serum VEGF level and vitreous VEGF level (r=0.314,P>0. 05). Conclusion ASD can decrease the VEGF level in vitreous,implying that ASD postpone the occurrence of diabetic retinopathy in DM rat.

Good prenatal and postnatal care and good preschool education are important approaches to raise the diatheses of population for the chinese nation. This article suggests that the cell phone platform can be used to communicate with each other among the hospitals, the government and the common people, through which the useful informations could be transmitted to the relative persons in time. It's also a new way for propaganda of family planning. This article introduces the structure of the system, the creation of the expert database, and the connection to the telecommunication system.

OBJECTIVETo explore clinical effects of drilling decompression for femoral head necrosis at collapse stage.
METHODSTotally 22 patients with femoral head necrosis on both side were analyzed from March 2006 to February 2009. Among them, there were 20 males and 2 females aged from 24 to 52 years old with an average of 38.4 years old. All patients were Ficat I on one side and Ficat I or II on another side. Drilling decompression were performed on all patients. The average followed-up period was 5.4 years (ranged, 1 to 8 years). The endpoint of severe pain(VAS ≥7), severe dysfunction (Harris ≤ 70), radiographic progression on Ficat IV and total hip arhtroplasty (THA) was used for survivorship analysis.
RESULTSSevere pain as an endpoint,13 cases were survived on Ficat III and 18 cases on Ficat I or II (P>0.05). Severe dysfunction as an endpoint, 6 cases were survived on Ficat III and 18 on Ficat I or II (P<0.05). Radiographic progression on Ficat IV as an endpoint, 2 cases were survived on Ficat III and 18 on Ficat I or II (P<0.05). THA as an endpoint, 13 cases were survived on Ficat I and 18 cases on Ficat I or II (P>0.05).
CONCLUSIONFemoral head necrosis with Ficat III treated with drilling decompression could prolong progression of disease , decrease percentage of THA.
