The precise measurement in lens thickness in vivo, provides great application value for intraocular accommodation and ametropia development mechanism research.And it has great clinical significance for the diagnosis and treatment of glaucoma and cataract.Currently, many ultrasonic methods and optical methods are used in measuring lens thickness.The measurement principles, advantages, disadvantages and the accuracy of the instruments are summarized in this paper.Among these methods, Orbscan II, Pentacam, Lenstar and AS-OCT can be used to measure lens thickness instead of A-scan.More important is the fact that UL-OCT can dynamically monitor the change of the lens thickness with intraocular accommodation.Choosing an instrument with higher measuring accuracy to examine the lens thickness, can provide more accurate and convincing lens thickness data for clinical and scientific research.

OBJECTIVETo construct primary cultured granulosa cells model of Zi Gooses tansfected by alpha-enolase (ENO1) overexpression adenovirus vector, and to detect the effect of ENO1 overexpression of granulose cells on progesterone secretion.
METHODSGranulosa cells were infected with Ad-CMV-ENO1 in gradient multiplicity of infection(MOI) levels:100, 250, 350 and 400 pfu/cell. Twenty four hours and 48 h after infection, green fluorescent protein (GDP) was respectively detected by fluorescence inverted microscopy. The effect of ENO1 overexpression of granulose cells on progesterone secretion was detected by the step double antibody sandwich enzyme-linked immunosorbent assay (ELISA).
RESULTSThe optimal infection rate (100%) was achieved when MOI was 800 pfu/cell,48h after infection. Real time RT-PCR and Western blot showed that the level of mRNA and protein expression ENO1 were increased significantly after infection (P < 0.01); The granulosa cells progesterone secretion of Ad-CMV-ENO1 group increased signigicantly (P < 0.01).
CONCLUSIONENO1 overexpression could make the primary culture follicle granulosa cells in vitro improve progesterone secretion.

[Objective]To investigate the efficacy of total hip arthroplasty(THA)on the treatment of traumatic arthritis that caused by internal fixation failures of intertrochanteric fractures.[Methods]During January 2009 and March 2016,35 cases of trau?matic arthritis(male:18 cases;female17 cases;49 ~ 86 years old,with an average age of 68.5 years)caused by internal fixation failures or malunion of intertrochanteric fractures,were undergo THA. Among 35 cases,13 cases were performed with the proximal femoral fixation stems,10 cases were with distal fixation stems,and 12 cases were with extended stems.[Results]With 3~65 months follow-up,the hip joint HSS score was elevated from 44.1(31 ~ 65)preoperative to 82.5(58 ~ 94)postoperative without obvious loosening. No postoperative deep infectionwas found. The femoral stems in 2 cases were found to sink 5 mm and 10 mm,respectively. No obvious prosthesis loosening was found. Taken together ,the satisfaction rate of THA on the joint function of traumatic arthritis was 91.4%.[Conclusion]Total hip arthroplasty is recommended as an effective approach for treating traumatic arthritis caused by internal fixation failures of intertrochanteric fractures. Distal fixed prosthesis was recommended due to bone sclerosis or defects of proximal femur. Coupled with emphasis on reconstruction of the greater trochanter ,good therapeutic effects could be achieved.

The mainly antigenic sites for the adenovirus neutraliation are present on Loop1 and Loop2 of hexon.Majority research were focus in the human adenovirus.Little was known on infectious canine hepatitis virus (ICHV), which was also called canine adenovirus typeⅠ.Here,ICHV (the isolated strain) DNA was isolated and purified from the cultured MDCK cells.The Loop1 and Loop2 fragments were amplified by polymerase chain reaction(PCR) method,and then was connected by ligase T4.The target fragment was then connected with vector pET28a.The nucleotide sequence ecoding Loop1 and Loop2 was determined.The nucleotide sequence identity of Loop1 region between the isolated strain and CLL, RI261 and Toronto A26/61 strains is 100%, 100% and 83.8%, and the nucleotide sequence identity of Loop2 region between the isolated strain and CLL, RI261 and Toronto A26/61 strains is 88.1% , 88.1% and 99.3%, and amino acid identity is 93.6%, 93.6% and 98.6%.The recombinant Loop protein was expressed in E.coli and was approximately 36kDa in size,and then was purified. Then BALB/c mice were injected subcutaneously in the back and armpit with the recombinant Loop protein.The anti-ICHV antibody titers of immunized serum was tested by indirect ELISA and the titers were up to 1:320.Western blot demonstrated that immunized sera could specifically combine with ICHV. The research laid a foundation for creating new genetic engineering products of infectious canine hepatitis virus.

OBJECTIVETo study the effect of nano-SiO2 on spatial learning and memory.
METHODSTwenty-four male rats were randomly divided into 3 groups: control group (C group), low dose group (L group) and high dose group (H group). The rats were intragastrically administrated with nanometer particles at 25 and 100 mg/kg body weight every day for 4 weeks. After exposure, the ability of learning and memory of rats was tested by Morris water maze, and electrophysiological brain stereotactic method was used to test long-tear potentiation (LTP) in dentate gyrus (DG) of the rats.
RESULTSThe increase rate of body weight in H group was reduced significantly compared with C group ( P < 0.05). In the space exploration experiment of Morris water maze test, the escape latency of H group was longer than that of C group (P < 0.05). The rats of H group spent less time in finding the target quadrant (P < 0.05) . The rate of LP induction of H group was significantly lower than that of C group (P < 0.05). After high fre quency stimulation (HFS), The changes of amplitude of population spike (PS) of L group and H group were lower than those of C group significantly (P < 0.05, P < 0.01).
CONCLUSIONNano-SiO₂may result in impairment of spatial learning and memory ability by reducing the rate of LTP induction and the increase of PS in hippocampus.
