Since functional visual acuity(FVA) was put foward,it is regraded as a kind of functional vision examination which can well reflect an individual' s performance in relation to certain daily activities involving visual tasks,the concept and the measurement is updating with the progress of technology.This examination was first applied in the patients with dry eye,and now it's applicable to detect and evaluate the refractive error,cataract,retinal pathological changes,or the eyedrops' use,and it can provide evidences for the early dignosis or the effects of thraphy of some ocular disease.In this paper,an introduction of the concept,methods and system of FVA,the clinical application of FVA in dry eye,refractive error,cataract,and in patients with fundus diseases and the research progress were reviewed.

Objective:To explore efficacy of the rehabilitative strategy in hospitalized schizophrenics.Method:Sixty-four schizophrenic patients were randomly divided into the intervention group and the control group.Both groups received the anti-psychotics therapy, but the teamwork education,medication management skills training module, symptom management skills training module were only given to the intervention group for ten weeks. And a one-year follow-up was carried out after their discharge from hospital. All subjects were evaluated with the Positive and Negative Syndrome Scale (PANSS), Nurses` Observation Scale for Inpatient Evaluation-30 (NOSIE-30), Insight and the Attitude to Treatment Scale, Social Disability Screening Schedule (SDSS), Morning Side Scale. We also recorded the relapse rate, reemployment rate, and re-hospitalization rate. Result:The clinical outcome of the intervention group was significantly superior to the control group on overall improvement according to PANSS (31.17?3.13 vs 52.34?13.02,7.34?1.08 vs 12.36?4.28,7.76?2.13 vs 13.26?4.50,16.13?1.82 vs 32.17?9.82 ),increase of active factor score of NOSIE-30 (-18.3?3.2 vs 14.4?6.7),and the reduction of inactive factor score of NOSIE-30(9.4?6.2 vs -22.3?7.4).The relapse rate(9.4% vs 54.8%),re-hospitalization rate(3.2% vs 42%),reemployment rate(37.5% vs 9.6%)were also better in the intervention group.Conclusion:The effect of rehabilitative strategy for schizophrenic patients not only improves the symptom, but also their social function.

Objective To evaluate prognostic factors for early bronchopleural fistula after pneumonectomy with non small cell lung cancer,and establish a validated clinical model to estimate the risk of early-BPF.Methods We reviewed the medical records of 429 patients who underwent pneumonectomy for NSCLC at our institution.We used univariate and multivariate analysis to identify potential independent risk factors for early-BPF after pneumonectomy for NSCLC.A model to estimate risk of early-BPF was developed by combining independent risk factors.Results The rate of early-BPF after pneumonectomy for NSCLC was 6.5％ (28/429).Three factors were independently associated with early-BPF:neoadjuvant therapy (HR:2.406),bleeding (HR:2.171)and diabetes (HR:1.144).A scoring system for early-BPF was developed by assigning 2 points for each major risk factor (neoadjuvant therapy and bleeding) and 1 point for each minor risk factor(diabetes).Scores were grouped as low (0-1),intermediate (2-3),and high (3),yielding the rate of early-BPF was 14％,27％,and 43％,respectively.Conclusion This clinical model is established on the basis of independent risk factors.This model can be used as a predictive tool for early-BPF after pneumonectomy for NSCLC.

Objective To study the protective effect on CCl4-injured L-02 hepatocytes of polysaccharides from Hyriopsis cumingii(HCP) and try to explain the mechanism.Methods The L-02 hepatocytes were incubated and then injured by CCl4.The levels of AST,ALT,MDA and SOD in cultural supernatant were detected by general methods.Cell viability was assayed by MTT method.Results The polysaccharides(25,250 and 1000?g?L-1)could reduce the levels of AST,ALT,MDA in cultural supernatant which increased by CCl4.It also could boost the hepatocytes viability and elevate the level of SOD which reduced by CCl4.Conclusion The results suggest that polysaccharides from Hyriopsis cumingii have direct protective activity on hepatocytes injured in vitro.It might be associated with the anti-oxidative activity of polysaccharides from Hyriopsis cumingii.

In this study,adults of Armillifer agkistrodontis (A.agkistrodontis) were collected from Agkistrodon acutus,and then the eggs were separated to feed mice.In the next step,when the infection model was established,blood serum of infected mice were collected after 1,2 and 3 weeks,respectively.Furthermore,ELISA and dot- ELISA were used to detect the dynamic change of specific antibodies and circulating antigens respectively.The specific antibodies increased from 8th week,reached the top at 12th week,decreased from 16th week,and then maintain at the same level constantly.Meanwhile,the specific antibodies were typed.It is evident that IgM antibody appeared first.However,it was substitute by IgG1 after 16 weeks.Moreover,the circulating antigens have been detected in the 1st week by dot-ELISA.Then,the dilution between 1:8 to 1:128were founded in 3rd week.The highest dilution with 1:256 appeared at 8th week,maintained before 11th week and then decreased gradually,which might provide a significant clinical implication for early diagnosis of circulating antigens.

Objective Bronchopleural fistula (BPF) is a common but potentially lethal complication after pulmonary resection.Currently,there is still controversy over the appropriate management strategy for BPF,especially when pleural space contamination develops.The purpose of this study was to evaluate the efficacy and safety of surgical repair fistulas combined with pedicled muscle flaps coverage in patients with early BPF after pulmonary resection based on our experience with 23 cases.Methods The clinical data for 23 patients who underwent surgical repair of early BPF from January 1999 to December 2010 at our hospital were reviewed.Thirteen patients had undergone a prior pneumonectomy and 10 patients had undergone a prior lobectomy.BPF occurred from postoperative day 5 to40 (mean postoperative day 21 ).Nine patients had a contaminated pleural space.After BPF was clearly diagnosed,prompt closed pleural drainage was instituted,followed by surgical repair of BPF.Four patients underwent a direct suture repair of fistula,ten patients underwent stump revision and suture closure,seven patients underwent stump revision and bronchoplasty or carina plasty,and a pedicled muscle flap was sewn to the edges of the fistula in two patients.The stump was covered with various muscle flaps,including interostal muscle flap in five cases,latissimus dorsi muscle flap in ten cases,serratus anterior muscle flap in six cases,and erector spinae muscle flap in two cases.Postoperatively,the pleural space was routinely irrigated and drained.Results No intraoperative or early postoperative death occurred.Four patients developed severs complications,including respiratory failure in two cases,pulmonary embolism in one case,and empyema in one case.All four cases recovered well after treatment.The mean duration of hospitalization was 33 days (range 8 - 120 days ).Surgical repair of BPF was successful in 21 cases (91.3％) but failed for 2 patients..BPF recurrence developed in only one patient two years postoperatively due to stump recurrence.He died of extensive metastatic disease 2 years after BPF recurrence.Conclusion Excellent results can be achieved by early surgical repair combined with stump pedicled muscle flaps coverage in patients with BPF who can tolerate reoperation,even if they have a contaminaled pleural space.

Objective To assess the effects of fenofibrate on myocardial remodeling in obese rats by echocardiography.Methods Twenty-six SD rats were fed with high fat chow to establish twenty obese rats models,which were randomly divided into two groups:obesity group (OB group,n =10) and fenofibrate group(F group,n =10).The same week-old SD rats group (n =10) was also randomly selected as normal control group.F group was given fenofibrate 60 mg · kg-1 · d-1 for 8 weeks,the other groups were given normal saline.Echocardiographic scan was performed in each group at the beginning and ending of the experiment.Twenty-four weeks later,all rats were executed and the cardiac muscle was used to histological inspect.Results After the experiment,compared with the control group,the body weight,the ventricular thickness,interventricular septal thickness and the left ventricular mass in OB group were significantly increased than those of control group(P ＜0.01),the E/A ratio was significantly decreased(P ＜0.01).Histological detection showed that myocardial structure was disordered,and that interstitial collagen was deposited in the myocardium.Compared with OB group,the parameters all above in F group were significantly improved (P ＜0.01).Left ventricular mass from echocardiography correlated well with the results from pathologic specimen (r =0.98,P ＜0.01).Conclusions Fenofibrate has beneficial effects on preventing myocardial remodeling.By general echocardiography,the effects can be assessed comprehensively and accurately.

Background Researches demonstrated that CpG ODN,a immunostimulatory sequences,has preventing and treating effect on allergic conjunctivitis caused by protein allergen.However,its effect on allergic conjunctivitis caused by fungal allergen is unclear. Objective This study aimed to investigate into whether the Th1-Th2 switching immunostimulatory CpG ODN could reverse the response in the murine allergic conjunctivitis model caused by aspergillus fumigatus. Methods A mixture of spores and hyphae of aspergillus fumigatus strain was used to induce allergic conjunctivitis in male BALB/C mice aged 6-8 weeks.This experiment was designed into preventive or therapeutical treatment program.Under both settings,allergic conjunctivitis of the animals were treated with CpG ODN,nonstimulatory GpC ODN or PBS.After the last challenge with the allergen,the clinical symptoms of the animals were scored based on the criteria of Magone.The animals were sacrificed and the histopathological examination of conjunctiva was performed.Expression of TLR4 mRNA in conjunctiva was analyzed by real-time PCR assay.The responsiveness and populations of lymphocytes in spleen and draining lymph nodes were analyzed by flow cytometry.The use complied with the Standard of Association for Research in Vision and Ophthalmology. Results In the prevention mode.CpG ODN decreased subconjunctival infiltration compared with GpC ODN and PBS groups with the average neutrophil count index(21.25 ±11.59/section,30.75 ±11.44 section and 69.00±9.90/section,respectively).Expression of TLR4 mRNA was up-regulated significantly by CpG ODN.The clinical scores for CpG ODN group were insignificantly lower than those in GpC ODN group and PBS group(P＞0.05).In the therapeutic mode,compared with GpC ODN and PBS groups,the allergic symptom score in CpG ODN group manifested significantly lower(t=4.000.t=2.750,P＜0.01)and showed fewer cellular infiltration(t=4.870,t=3.829,P＜0.01)and higher expression of TLR4 mRNA(P＜0.01).In cultured splenic and draining lymph node cells,increased percentages of CD4+ CD25+ and CD4+ CD25+ CD69+ in CpG ODN group were observed compared with control groups(|P＜0.05). Conclusion CpG ODN can relieve aspergillus fumigatus-induced allergic conjunctivitis via either subconjunctival injection or topical application by upregulating expression of TLR4 and activating Treg lymphocytes.
