Proteins extracted from two varieties of Chinese roses leaves were separated by two- dimensional polyacrylamide gel electrophoresis (2-DE) with immobilized pH gradient (IPG). Many difference proteins were isolated with molecular weights ranging 10-30 kDa and pI5-6. Three proteins of high levels observed in a gel were excised and identified using peptide mass fingerprinting and MS-MS. A summary of the identified proteins and their putative functions are presented. They are identified as eIF-5A、LEA protein and Hsp17. 5. Functions of these proteins in plant tolerance to high temperature were discussed.

·AlM: To investigate pathogeny and effects of surgery on paralytic strabismus.
· METHODS: A retrospective study was done in 46 patients with paralytic strabismus who underwent squint correction in our hospital from June 2010 to June 2013. Among 26 horizontal strabismus, the cases of extra rectus palsy was 16, internal rectus palsy was 10.Among all20 vertical strabismus, the cases of superior oblique palsy, superior rectus palsy, inferior rectus palsy, double elevator palsy counted for 7, 8, 2 and 3, respectively. Pathogenesis: trauma was 19 cases, followed by 10 cases that the causes could not be identified.Nine was congen ital paralytic strabismus, 8 o ccurred after nose or brain surgery. The surgery methods included rectus muscle recession, rectus muscle resection, partial rectus muscle transposition, Jensen procedure, inferior oblique myectomy and anterior transposition of inferior oblique. Statistical software SPSS10.0 was used in chi-square test between two groups, while the situation of paralysis eye movements improved by two methods in the horizontal strabismus group was compared with t test.
· RESULTS: Among all horizontal strabismus the rate of cure, improvement and inefficiency was 20 ( 77%) , 5 ( 19%) and 1 ( 4%) , respectively. Among vertical strabismus the ratio of cure, improvement and inefficiency was 15 (75%), 3 (15%) and 2 (10%).There was no significantly difference between the two groups ( P >0.05 ). The movements of paralytic eyes were improved. Two procedures used in horizontal strabismus, can improve paralysis eye movements were 3.76 ±0.91, 3.72 ±0.84mm, with no significant difference (P=0.93) statistically.
· CONCLUSlON: Paralytic strabismus in adults had complicated conditions. Choosing different operation methods in treating paralytic strabismus according to the degree of paralysis can result in satisfactory cosmetically alignment of the eyes and modify head position and diplopia.

Objective To report our surgical experience in treating 19 cases of solitary iliac aneurysms (SIA). Methods The clinical data of 19 consecutive patients with SIA between January 1985 and January 2008 were retrospectively reviewed. There were 18 men and 1 woman, aging from 39 to 77 years ( mean 62 ± 7 years). Results There were 30 SIAs in the 19 patients, including 25 ( 83.3% ) common iliac aneurysms, 4 (13.3%) internal ihac aneurysms and 1 (3. 3% ) external iliac aneurysm. Eleven patients ( 57.9% ) had multiple ancurysms, with 9 patients ( 47.4% ) having bilateral SIA. Two patients had coexistent peripheral vascular occlusive disease. There were 2 patients suffering form ruptured SIA, one was saved by emergency operation and one died before an surgery could be attempted. Seventeen patients underwent successful open aneurysmectomy and artificial graft implantation leaving no ischemic complications of the pelvic organs. One patient with right common iliac aneurysm underwent endovascular repair without endoleak. There was no operative death during porioperative period. The surviving patients remained stable and had good patency of grafts during the follow-up period. Conclusions Early management of SIA is important, CT angiogarphy (CTA) is necessary not only to evaluate the SIAs, but also to detect multiple aneurysms or arterial occlusive disease. Close and long-term follow-up is mandatory for the early detection of the formation of new anearysms.

The vitamin K epoxide reductase complex subunit 1 (VKORC1), the rate-limiting enzyme for vitamin K recycling, is significantly down-regulated in the kidneys of urolithiasis patients. This study searched for direct evidence to define the inhibitory activity of VKORC1 against calcium oxalate (CaOx) crystal formation. In the experiment of VKORC1 overexpression, HK-2 cells were transfected with the pFLAG-CMV-7.1-VKORC1 plasmid as a pFLAG-CMV-7.1-VKORC1 transfection group or the pFLAG-CMV-7.1 plasmid as a pFLAG-CMV-7.1 control group. In the experiment of VKORC1 knockdown, HK-2 cells were transfected with the PGPU6/GFP/Neo-VKORC1shRNA-2 as a PGPU6/GFP/Neo-VKORC1shRNA-2 transfection group or the PGPU6/GFP/Neo-shRNA-NC plasmid as a PGPU6/GFP/Neo-shRNA-NC control group. The expression of VKORC1 in HK-2 cells was detected by real-time quantitative PCR and Western blotting. The CaOx crystal formation was observed under the laser-scanning confocal microscope. It was found that the expression levels of VKORC1 mRNA and protein were significantly higher in the pFLAG-CMV-7.1-VKORC1 transfection group than in the pFLAG-CMV-7.1 control group (P<0.01). The number of CaOx crystals in HK-2 cells incubated in fluorescently labeled CaOx monohydrate (COM) crystal medium for 48 h was 14±4 per field (100×) in the pFLAG-CMV-7.1-VKORC1 transfection group and 26±5 per field (100×) in the pFLAG-CMV-7.1 control group respectively under the laser-scanning confocal microscope. The amount of CaOx crystal aggregation and formation in the pFLAG-CMV-7.1-VKORC1 transfection group was significantly reduced as compared with the pFLAG-CMV-7.1 control group (P<0.05). The expression levels of VKORC1 mRNA and protein were significantly lower in the PGPU6/GFP/Neo-VKORC1shRNA-2 transfection group than in the PGPU6/GFP/Neo-shRNA-NC control group (P<0.05). The number of CaOx crystals in HK-2 cells incubated in fluorescently labeled COM crystal medium was 65±11 per field (100×) in the PGPU6/GFP/Neo-VKORC1shRNA-2 transfection group and 24±6 per field (100×) in the PGPU6/GFP/Neo-shRNA-NC control group respectively under the laser-scanning confocal microscope. The amount of CaOx crystal aggregation and formation in the PGPU6/GFP/Neo-VKORC1shRNA-2 transfection group was significantly increased as compared with the PGPU6/GFP/Neo-shRNA-NC control group (P<0.05). These findings suggested that the VKORC1 protein could inhibit CaOx salt crystallization, adhesion and aggregation. This research would help us to understand the mechanisms involving the interaction between crystallization and epithelial cells and the formation of CaOx.

Objective To study the diagnosis and treatment of cytomegalovirus (CMV) infection after liver transplantation. Methods The clinical data of 111 patients who received liver transplantation from November 2000 to December 2007 in our hospital were analyzed retrospectively. The recipients were diagnosed as having CMV infection by the predisposing factors, clinical symptoms and detection of CMV-PP65 and CMV-IgM in peripheral blood specimens in combination with chest X-ray. The treatment of CMV infection was administration of Ganciclovir. Results Five recipients were diagnosed as having CMV infection, with the incidence of 4.5%. Two were diagnosed as having CMV pneumonitis, with the incidence of 1.8% (40% of the recipients having CMV infection). Two were both improved. Three were diagnosed as having CMV active infection. Two of them were cured and one was improved. Conclusion The detection of CMV-PP65 is necessary for early diagnosis and guiding treatment of CMV infection. Ganciclovir can exert significant therapeutic effects on CMV infection.

PURPOSE: The purpose of this study was to evaluate the 15.5 year long term survival rate of the Precoat femoral stem. MATERIALS AND METHODS: We reviewed the results of 105 primary hybrid total hip replacements (98 patients) that were performed by one surgeon between October 1990 and August 1995 using a cemented polymethyl-methacrylate coated femoral prosthesis (Precoat) and contemporary cementing techniques. Thirty four patients (34 hips) died and seventeen patients (17 hips) were lost to follow-up. Forty seven patients (54 hips) were available for clinical follow-up, with an average follow-up period of 15.5 years (range: 8.4 to 18.3 years). The average age of the patients at the time of the index operation was 46 years (range: 22 to 67 years). There were 32 male patients (37 hips) and 15 female patients (17 hips). RESULTS: For the acetabular component, 15 hips (27.8%) were revised for cup loosening and isolated liner exchange was performed in 12 hips (22.2%) for liner wear and osteolysis. For the femoral component, 12 hips (22.2%) were revised due to aseptic loosening. Of these twelve hips, 3 hips had Grade B cement mantles and 9 had Grade C cement mantles. The clinical results of the 54 retained hips were good or excellent in 52 hips (96.3%) with the average Harris hip score being 88 points (range: 72 to 96 points). CONCLUSION: The mean 15.5 years' survival rate of the Precoat cemented femoral stem was 78%. We think that there were several factors for the failure of femoral stem fixation, including age, physical activity and the body weight, as well as the stem design and the surgical technique had an influence on the stem's survival.

OBJECTIVETo construct a replication-defective recombinant adenovirus expressing the ORF2 (112-660aa) antigen of hepatitis E virus (HEV) and evaluate its immunization effect in BALB/c mice by mucosal inoculation.

METHODSThe HEV ORF2 gene encoding for 112-660aa was amplified from plasmid pUC-HEV and inserted into the transfer vector pTrack-CMV. The recombinant plasmid and adenoviral backbone plasmid pAdEasy-1 were co-transformed into E. coli strain BJ5183. Taking the advantage of the high efficient homologous recombination machinery presented in bacteria, the recombinant adenovirus backbone plasmid was generated in BJ5183, and then was transfected into 293 cells. Recombinant Adenoviruses were propagated in 293 cells with high titers. 8-week-old BALB/c mice were inoculated intraperitoneally and intranasally with 10(7) pfu recombinant adenovirus each on weeks 0, 3, 5, 7, 10.

RESULTSBoth groups of mice induced humoral IgG immune response with the highest titers 1:1,000 and 1:10,000 each. Only the group inoculated intranasally could induce mucosal IgA immune response.

CONCLUSIONSThe adenoviral recombinant can stimulate specific humoral and mucosal immune response in mice and is potentially to be used as a candidate vaccine for the treatment of HEV infection.

OBJECTIVETo evaluate the CD4+CD25+ regulatory T cells (Treg) and other lymphocyte subsets in the peripheral blood of patients with advanced lung adenocarcinoma.

METHODSPeripheral blood samples were obtained from 64 patients with advanced lung adenocarcinoma (case group) and analyzed by flow cytometry. The ratios of CD4+CD25+Treg T cells and other T lymphocyte subsets in peripheral blood were compared with those from 33 healthy controls (control group).

RESULTSThe percentages of CD3+ and CD3+CD4+ were (66.5±11.0)% and (37.7±10.6)% respectively in the peripheral blood of the case group, which were significantly lower than those [(72.0±6.0)% and (42.0±6.4)%] in the control group (t=-3.2,-2.4; P=0.020, 0.015, respectively). The ratio of CD4+ CD25+ Treg cells in case group (10.5±4.0)% was significantly higher than that [(8.4±3.5)%] in the control group (t=-2.2, P=0.013). CD4+/CD8+ value of case group (1.4±0.8) was significantly lower than that (1.8±0.7) in control group(t=-2.2, P=0.029). CD3+CD8+, CD8+CD28-, and CD8+CD28+ showed no significant differences (all P>0.05). Smoking, differentiation grade, and size of the tumor showed no association with the function damage of T lymphocyte subsets, while the carcino-embryonic antigen level did.

CONCLUSIONSIn patients with advanced lung adenocarcinoma, Treg increases and CD4+/CD8+ decreases, suggesting remarkably suppressed immune functions. However, more research is warranted to validate the association of T cells subset dysfunction with smoking, differentiation grade, and size of tumor.
