Objective To understand the development of psychosocial adaptation and life quality of patients with visual impairment, as well as their relationship. Methods Researches about impact of psychosocial adaptation on life quality of patients with visual impairment underwent document retrieval and the results went through analysis. Results Cataract, glaucoma, retinal detachment, diabetic retinopathy, age-related macular degeneration caused different degree of visual impairment, furthermore influence physical, psychosocial adaptation and life quality of these patients. Some scales were compiled by some scholars at home and abroad to evaluate the influence degree of these factors, but tools to test psychosocial adaptation lacked. Conclusions Researches on quality of life for a single eye impairment are more than those on the relationship between psychosocial adaptation and quality of life. At the same time, it is necessary to develop a tool to measure psychosocial adaptation of visual function impairment.

Minichromosome maintenance proteins (MCMs) are the primary control factors for eukaryotes DNA replication.MCMs play important roles in the starting place and the extending process of DNA replication.MCM2,one member of MCMs,expresses little in stationary phase while highly in proliferative and transformational phase.MCM2 can accurately reflect the cell proliferation activity and is considered as a specific maker for carcinoma and precancerous lesions.The overexpression of MCM2 is closely correlated with the genesis and development of tumors,and it maybe a good maker for early screening and prognosis assessment in many cancers and used in clinical.

Objective:To detect anti-LKM-1 antibody with enzyme-linked immunosorbent assay (ELISA) using a recombinant fusion peptide which comprises 257-351 amino acid fragment of CYP2D6 as antigen.Methods:We obtained CYP2D6 cDNA fragment by means of PCR,using total liver cDNA library as the template.The PCR products were ligated into pEGH expressing vector to construct the recombinant expressing vector with high efficiency in Saccharomyces Cerevisiae Y258.The positive clones were identified by PCR reaction and then induced by galactose.Glutathione-Sepharose 4B was used for purification of recombinant CYP2D6 protein.After affinity purification,the antigenicity was identified with Western blot.Serum samples from 26 patients who were positive for anti-LKM-1 antibody,20 patients with other connective tissue disorder(CTD) and 30 normal controls were retrospectively tested with ELISA.Results:A fusion peptide was expressed and purified.The antigenicity was confirmed with Western blot using standard of anti-LKM-1 antibody-positive serum.Of the 26 serum samples which are positive for anti-LKM-1 antibody,5 of 6 samples positive for anti-HCV antibody also recognized the recombinant fusion peptide with ELISA,only one serum sample which was showed positive anti-HCV antibody displayed a negative result in ELISA assay.All other 20 patients with positiv anti-LKM-1 antibody were shown positive in ELISA assay using this recombinant peptide.All the serum samples from patients with other CTD were negative in ELISA assay.Conclusion:The recombinant antigen fragment contains major epitope regions in natural CYP2D6 antigen.Detection of anti-LKM-1 antibody with ELISA using the recombinant peptide can improve the sensitivity and has a potential role in determining its clinical association.

Objective To evaluate the effect of postoperative patient controlled epidural analgesia (PCEA) on respiratory function in patients aged over 65 years Methods 41 ASA Ⅰ Ⅱ patients (male 22,female 19)aged between 65 80 years, weighing 58 78kg, scheduled for upper abdominal surgery were divided randomly into two groups: control group(n=20)and PCEA group(n=21) Epidural block was performed at T 8 9 with an epidural catheter inserted cranially for 4 cm A test dose of 1 5% lidocaine 4 5ml was given via epidural catheter When epidural blockade was confirmed, general anesthesia was induced with diazepam 0 2mg?kg -1 ,etomidate 0 3 mg?kg -1 ,fentanyl 4?g?kg -1 and vecuronium 0 1mg?kg -1 ,and maintained with epidural 0 5% bupivacaine infusion (6 7ml/2h) combined with inhalation of low concentration of isoflurane and intermittent iv boluses of fentanyl and vecuronium For postoperative analgesia in control group intramuscular pethidine was given on demand; In PCEA group PCEA was used A loading dose of 3ml of 0 15% bupivacaine mixture (morphine 10mg and haloperidol 5mg/0 15% bupivacaine 100ml) followed by continuous infusion of 0 5 1ml/h Superimposed by boluses of 2ml with a lock out time of 25min The maximal amount of bupivacaine mixture was 8ml/h VAS, Bruggman′s comfort scale and Rawsay′s sedation score were evaluated BP, HR, respiratory rate (RR) and SpO 2 were measured and recorded every 30min 4 h after operation Vital volume, Forced vital capacity, forced expiratory volume (first second:FEV 1 0 ),PEEP, MMEF were measured before operation and on 1st,3rd,5th and 7th postoperative days Blood gas analysis was checked before operation, during operation (30min and 90min after induction of anesthesia) and the 1st,3rd, 5th and 7th postoperative days Results The total amount of narcotic in 72h was 11 36mg (morphine equivalent dose) in control group and 5 4mg in PCEA group VAS was higher in control group than PCEA group The postoperative respiratory function was significantly better in PECA group Conclusions In elderly patient after upper abdominal operation PECA can greatly improve the respiratory function with better analgesia

Sixty patients underwent surgery for malignant thoracic tumor were evenly randomized into control group (group A) and treatment group (group B).0.3 ml low-molecular-weight heparin was injected per 12 h for 3 d in group B from 24 h after surgery.Bilateral venous sonography of lower extremities were performed before and d1,d3 after operation.Blood coagulation marks PLT,PT,APTT,Fibrinogen (FIB)and D-dimer were determined at the same time.Diagnosis of calf vein thrombosis after surgery was confirmed by color Doppler sonography in 7 patients:1 in group B (3％) and 6 in group A (20％) (P ＜ 0.05 ).Thrombosis at calf intermuscular vein was found in 6 patients and thrombosis at posterior tibial vein in 1 patient.FIB and D-dimer had no significant difference on the dl ( P ＞ 0.05 ) between two groups,but significantly lower on the d3 after surgery in group B than that in group A ( P ＜ 0.05 ).Low-molecularweight heparin reduced blood hypercoagulation state and thrombosis.Color Doppler sonography can be a valuable method for detecting asymptomatic deep vein thrombosis in the early stage after surgery and monitoring the efficacy of thrombosis prevention.

Objective To examine the expression of metastasis-associated in colon cancer 1 (MACC1) gene in ovarian cancer cell lines and investigate its effect on biological behaviors of ovarian cancer cells.Methods The expression of MACC1 was examined by qRT-PCR and Western blot analysis in four ovarian cancer cell lines inculding OVCAR3,ES-2,SKOV3 and HO-8910.When the MACC1 was transfected to OVCAR3 cells,fluorogenic quantitative PCR was used to filter and identify MACC1 gene after the efficient silencing.Changes of adhesion in the cells were analyzed by an adhesion assay.Transwell migration and invasion assay and in vitro vascular mimicry assay were used to detect migration,invasion and angiogenesis of OVCAR3 cells in vitro.Results The expression of MACC1 gene was higher in OVCAR3 compared to other cell lines.qRT-PCR confirmed that the expression of MACC1 was silenced successfully after transient transfected MACC1-siRNA into OVCAR3 cells.After successful silencing the MACC1 expression,the adhesion ability was inhibited to some degree.In transwell migration assay,the numbers of cells in upper chamber passing through the membrane in transfected group were less than control groups (245.5 ±12.8,500.3±16.5 and 496.3±13.1 respectively),while in transwell invasion assay,the numbers of cells in upper chamber passing through the membrane in transfected group were less than the negative group and control group (185.3±14.1,405.7±9.1 and 416.3±11.5 respectively),both with markedly differences among the three groups.In tube formation assay,the distrubition of HUVECs was diffused with less junctions,and the average number of complete tubular structure was decreased in transfected group compared to the corresponding controls.Conclusion RNA interference inhibits the expression of MACC1 and effectively inhibits the metastasis and invasion abilities of ovarian cancer cells in vitro,and MACC1 is expected to become the target gene of ovarian cancer treatment.

Objective:To investigate the rationality of anti-fungal agents for deep fungal infection used in one hospital and the effects of national rectification of antimicrobial drugs. Methods: The retrospective analysis method was used to survey the inpatients administrated anti-fungal agents for deep fungal infection from April 2010 to Mard 2012, and assessed the rationality. Results:The ir-rational utilization of anti-fungal agents for deep fungal infection included loading dosage lack during the treatment,inappropriate loading dosage and administration frequency. The irrational utilization of anti-fungal agents for deep fungal infection was decreased significantly (P<0. 05)after the national rectification of antimicrobial drugs. Conclusion:After the national rectification of antimicrobial drugs, the hospital can amtrol the irrational use of anti-fungal agents to some extent, while still needs more management and education.

Objective To investigate the effect of reformative ventilation method (head-high leg-low 30°-declivate prone position ) in the ventilation of acute respiratory distress syndrome ( ARDS ) patients, and compared with normal prone position ventilation. Methods Forty-four patients of ARDS underwent ventilation were divided into prone position group (22 cases) and reformative prone position group (22cases) by random digits talle. Continuous 30° semireclining position was kept in normal time. The patients of the two groups underwent different prone position ventilation 4 hours every day,and indexes of hemodynamics and respiration before,during and after prone position ventilation were recorded and analyzed. Results After prone position ventilation, oxygenation index of two groups improved similarly (P ＞ 0.05 ). In prone position group, lung compliance decreased [2 h, ( 25.6 ± 5.8 ) ml/cm H2O ( 1 cm H2O = 0.098 kPa) vs. ( 37.2 ± 20.5 )ml/cm H2O] ,average airway pressure increased [2 h, ( 18.5 ± 3.9) cm H2O vs. ( 15.6 ± 5.3 )cm H2O] ,heart rate increased [2 h, ( 112.0 ± 16.2 ) beats/min vs. ( 102.0 ± 11.3 ) beats/min], mean arterial blood pressure decreased [2 h, (86.0 ± 6.7) mm Hg ( 1 mm Hg = 0.133 kPa) vs. (93.5 ± 7.5 ) mm Hg] ,central venous pressure increased[2 h, ( 15.5 ± 3.3 ) cm H2O vs. ( 12.6 ± 4.3 ) cm H2O]. These changes persistently existed during prone position ventilation (P ＜ 0.05 ),and they disappeared in 1 hour when recovered to 30 °semireclining position. Conclusion Reformative prone position ventilation not only has same effect on improving oxygenation index, but also obviates adverse effect on lung compliance and hemodynamics.

Objective To study the express of matrix metalloproteinase(MMP)-2 and tissue inhibitor of metalloproteinase(TIMP)-2 protein in human endometrial carcinoma. Methods The Immunohistochemistry was used to measure the MMP-2, TIMP-2 in endometrial carcinoma tissue of 40 patients, the atypical hyperplasia of 12 samples and the normal endometrium of 12 samples. Results The positive express of MMP-2 and TIMP-2 in the normal endometrium , atypical hyperplasia and endometrial carcinoma was increased gradually. In endometrial carcinoma, with progression of clinical stage and decrease of histological grade as well as deepening of cancer invasion, the ratio of MMP-2/TIMP-2 was increased. Conclusions The expression of MMP-2 and TIMP-2 were connected with endometrial carcinoma. The imbalance of MMP-2/TIMP-2 in the endometrial cancer might be one of the pathogenesis and development.
