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.

Sodium pentachlorophenol (Na-PCP) has been used in China for years as a molluscacide to kill on-comelania, which is an intermediate host of schistosome. Large amounts of the powerful pesticide spayed over vast areas to control schistosomiasis contaminated the surface water sources, soil, sediment, animals and plants. Also it intruded into human body through food chain. Recently many studies that concern the endocrine disrupting effects of pentachlorophenol (PCP) were conducted. Animal studies showed that PCP/ Na-PCP could interfere in the normal function of thyroxine in many species, but without any effects on estrogen and testosterone. It was also found that PCP/ Na-PCP could effectively inhibit the activity of the human progesterone receptor (hPR) in yeast and interfere with the binding of physiological ligands to steroid receptors and binding proteins. Some epidemiologic data showed that PCP might interfere the normal endocrine function of female and paternal occupational exposure to PCP/Na-PCP could be associated with an increased risk of congenital anomalies or other adverse reproductive outcomes in offspring. All these findings indicate that pentachlorophenol could disrupt the normal function of endocrine system, but to con-firm that pentachlorophenol is one kind of endocrine disruptor and understand thoroughly the mechanism of PCP on endocrine system, more studies are needed.

Objective To compare the cost-effectiveness of montelukast and salbutamal for the treatment of children with airway hyperresponsiveness (AHR) after mycoplasma pneumoniae(MPP). Methods A total of 374 children with pneumonia during Oct. 2007 to Oct. 2008 were observed, and 185 of them had mycoplasma infection (four-fold or greater rise by paired serum sample or higher than 1 : 160 by a single serum sample). Of the 185 patients 118 complicated with AHR were included for cost-effectiveness analysis. They were divided into three groups, namely, routine treatment (group A), routine treatment plus salbutamal (group B), routine treatment plus montelukast (group C). The incidence, duration and alleviating time of stimulating cough and hospital stay were observed in the three groups. The peak expiratory flow (PEF) was also determined. Cost- effectiveness analysis was performed using the costs of the first class second level hospital in Shanghai. Results The incidence of AHR was 63. 8% in children with mycoplasma infection pneumonia in our group. Montelukast and salbutamal shortened the course of stimulating cough compared with group A. Cost-effectiveness analysis revealed that the cost of salbutamal was less than that of montelukast, with the cost-effectiveness ratio being 0. 86(P<0. 05). Conclusion Salbutamal is more cost-effective than montelukast for MPP children without other complications, which is a valuable information for clinicians.

The inheritance of famous old traditional Chinese medicine (TCM) doctors plays an essential role in the fields of TCM research. Qualitative interviews allow for subjectivity and individuality within clinical experience as well as academic ideas of doctors, making it a potential appropriate research method for inheritance of famous old TCM doctors. We summarized current situations of inheritance research on famous old TCM doctors, and then discussed the feasibility of applying qualitative interviews in inheritance of famous old TCM doctors. By combining our experience in research on inheritance of famous old TCM doctors, we gave some advice on study design, interview implementation, data transcription and analyses , and report writing, providing a reference for further relevant research.

BACKGROUND:Research on liver transplantation has not just focused on survival rate and survival time, and the quality of life has become a new field of study. However, it is stil a blank about the quality of life of liver transplant recipients in Xinjiang. OBJECTIVE:To investigate the quality of life of liver transplant recipients in Xinjiang and to explore the main risk factors for the quality of life in patients. METHODS: A Chinese version of the SF-36 health survey was used to retrospectively evaluate the quality of life of liver transplant recipients in Xinjiang. RESULTS AND CONCLUSION:The scores of al eight dimensions in the patients with liver transplantation ranged from 60.6±18.7 to 93.9±22.1. Primary diseases, operation method, marital status, level of education, occupation, gender and age could influence the quality of life of the liver transplant recipients, but nation, income and the way of medical insurance had no significant effect on the quality of life. These findings indicate that there is no obvious difference in the quality of life between liver transplant recipients and normal population, and the scores in six dimensions are higher in the liver transplant recipients than normal population, which is further confirmed that liver transplantation is an effective way for treatment of advanced liver disease.

Objective To investigate the significance of bone marrow cell morphology on clinical diagnosis of children hematopoietic diseases.Methods The data of bone marrow cell morphology in the bone marrow puncture specimens from 4 590 children admitted to Children' s Hospital of Shanxi Province from January 2009 to December 2014 were retrospectively analyzed.Results The proportion of infancy patients was the highest in 4 590 bone marrow specimens, accounting for 29.0 ％ (1 333/4 590), then that of the toddler age patients was second highest, accounting for 26.7 ％ (1 224/4 590).The constituent ratio of thrombocytopenic purpura (ITP) at the different ages was the highest.The most common diseases in bone marrow cell morphology diagnosis were in order of ITP, iron deficiency anemia (IDA), infectious bone marrow, leukemia (acute lymphoblastic leukemia, acute myeloid leukemia), aplastic anemia and so on.Conclusions Accurate analysis of bone marrow cell morphology is still the most basic and rapid approach in children with hematopoietic system disease, which has important value.Except hematopoietic system diseases, once fever of unknown origin, hepatosplenomegaly and enlargement of lymph nodes the patients should be early given bone marrow cell morphology check, early diagnosis and therapy.

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.
