AIM: To investigate clinical effects of local resection of eyelid tumors and pathological examination or frozen section examination as well as the stage I recovery.
METHODS: For all 92 cases 92 eyes of eyelid tumor patients who underwent local resection, reconstruction in stage Ⅰ and routine pathological examination ( 37 cases of suspected malignant tumors using frozen section examination. If it was malignant, excision by Moths surgery) . Using free palate mucosa autograft in stage I or reconstruction by Hughes surgery combined with eye flaps repaired eyelid defects.
RESULTS: The postoperative pathological diagnosis:52 cases were benign tumors, and 40 cases malignant tumors. All cases of eye flaps and hard palate mucosa grafts were survived. Followed up for more than 6mo, no tumor were recurred. The appearance and function of eyelid were satisfactory.
CONCLUSION: In this group of cases, nearly half of eyelid tumors are malignant tumors. It should be treated and operated as early as possible. For suspected malignant tumors, we use frozen section examination to confirm its properties in order to excision cleanly in stageⅠ, reducing the recurrence and metastasis. According to the eyelid defect after resection, we could do repair operation in stage Ⅰ. The inner larger defect is repaired by using hard palate mucosa transplantation or Hughes surgery. The outer layer of the eyelid defect is repaired by using eye flap glide, the free flap, the kite flap, the simple suture, etc. It should be careful when using the hard palate mucosa transplantation in the upper eyelid defect.

Objective To evaluate the effects of hydroxyapatite (HA) extensively-coated prosthesis on elderly patients undergoing hip arthroplasty.Methods From February 1997 to May 1999,96 patients Were treated with hydroxyapatite (HA) coated prosthesis and followed up for their hip arthroplasty.Their results were studied clinically and roentgengraphically to evaluate chiefly their Harris scores,complications and thigh pain.The survival of prosthesis was evaluated according to Kaplan-Meier methods.Results The 60 cases were followed up for eight years on average(range,sevon to nine years).Their mean Harris scores were improved from 42 preoperatively to 90 postoperatively.Fifty-eihgt cases felt no pain at their hip,but two did at their thigh.No radiolucent lines were observed.All the prostheses achieved bony stabilization and remolding.Conclusions HA coated prosthesis can achieve fine fixation,because it helps bone conduction,resists axial force and torsion,and reduces operative risks.

Survivin is a protein that inhibits apoptosis and regulates cell division.The cDNA sequence of survivin was amplified by RT-PCR and sub-cloned into the prokaryotic expression vector pET-21b(+),followed by transformation into E.coli strain BL21(DE3) and induction with IPTG.The recombinant survivin protein fusing with 6?His tag was expressed in E.coli in the form of inclusion body at the expression level over 60% of the total cell protein.Results of Western blotting showed that recombinant survivin reacted specifically with anti-human survivin antibody.After gel filtration,the recombinant protein reached the purity over 95%,which facilitate the study of diagnosing and inhibitor agents targeting survivin.

AIM: To explore the clinical effects of high frequency electrical capsulotomy in maturation period cataract surgery.
●METHODS: A total of 68 cases of maturation period cataract were selected and underwent the surgery of continuous circular capsulorhexis using the high frequency electrical capsulotomy.
●RESULTS: The success rate was 91% in 68 cases with the high frequency electrical capsulotomy.
● CONCLUSION: The high frequency electrical capsulotomy in maturation period cataract surgery has significant advantages and brilliant clinical values.

The fruit of Pandanus tectorius (PTF) has a long history of use as a folk medicine to treat hyperlipidemia in Hainan province, South China. Our previous studies have shown that the n-butanol extract of PTF is rich in caffeoylquinic acids and has an adequate therapeutic effect on dyslipidemic animals induced by high-fat diet. In this work, seven caffeoylquinic acids isolated from PTF were screened for the lipid-lowering activity in HepG2 hepatoma cells. Oil-Red O staining, microscopy and intracellular triglyceride (TG) and total cholesterol (TC) quantification showed that 3-O-caffeoylquinic acid (3-CQA), 3, 5-di-O-caffeoylquinic acid (3,5-CQA), and 3,4,5-tri-O-caffeoylquinic acid (3,4,5-CQA) significantly inhibited lipid accumulation induced by oleic acid and decreased intracellular levels of TC and TG in a dose-dependent manner. These three caffeoylquinic acids showed no significant cytotoxicity at concentrations of 1 -50 μmol x L(-1) as determined by MTT assay. Realtime quantitative PCR revealed that 3-CQA and 3, 5-CQA significantly increased the expression of lipid oxidation-related genes PPARα, CPT-1 and ACOX1 while 3-CQA, 3, 5-CQA and 3,4,5-CQA decreased the expression of lipogenic genes SREBP-1c, SREBP-2, HMGR, ACC, FAS. Overall, 3-CQA, 3, 5-CQA and 3, 4, 5-CQA may be the principal hypolipidemic components in PTF which can decrease intracellular lipid accumulation through up-regulating the expression of lipid oxidative genes and down-regulating the expression of lipogenic genes.

Objective:To explore clinical and histopathological characteristics of primary biliary cirrho-sis-autoimmune hepatitis overlap syndrome.Methods:Clinical data and pathological findings of 10 pa-tients were reviewed.Results:Serum glutamine transpeptidase,alkaline phosphatase levels,alaninetransaminase,aspartate transaminase,serum IgG and IgM were elevated in all the patients.They were allpositive for anti-mitochondrial antibody and AMA-M2.Nine patients were positive for anti-nuclear anti-body and one patient was positive for anti liver-kidney microsome antibody.Liver biopsies in these pa-tients revealed:ten patients had bile duct lesion,hepatitis activities ranged from moderate to severe,andfibrosis ranged from S1 to S3.Conclusion:PBC-AIH overlap syndrome is mostly found in middle-agedwomen.It has the clinical and histopathological characteristics of both PBC and AIH.Accurate andprompt diagnosis of overlap syndrome patients should be based on the clinical presentation,biochemicaland immune indexes,and hepalic pathological changes.
