Adult-onset foveomacular vitelliform dystrophy (AFVD) is characterized by gradually loss of vision,subretinal vitelliform macular lesions and retinal pigment epithelium (RPE) atrophy.The electrooculogram (EOG) is usually normal or reduce slightly.On optical coherence tomography (OCT),there are vitelliform substance which deposited between the photoreceptor layer and the RPE layer,and thinner outer nuclear layer above these deposits.OCT angiography can show the superficial and deep retinal capillaries plexus (DCP) above the yolk-like deposits,the choroidal capillary blood flow is reduced and the DCP blood flow is increased near macular.On indocyanine green angiography (ICG),there is choroidal neovascularization under vitelliform substance at early stage and fluorescence leakage in the corresponding retinal region at late stage.There is no effective treatment for AFVD at present,monogenic gene therapy is the most worth looking forward to.Understanding AFVD clinical manifestations,multi-mode imaging features and new advances in treatment can provide a reference for diagnosis and treatment options

Objective To investigate the changes of the levels of high sensitivity reactive protein C (hsCRP), white blood cell (WBC) and fibrinogen (FIB) in type 2 diabetic patients with metabolic syndrom (MS). Method 323 inpatients with type 2 diabetes were divided into MS group and non-MS group according to their clinical dates, and the changes of the levels of hsCRP, WBC and FIB in the two groups and the relationship between their levels and MS were analyzed. Results Compared to non-MS group, the levels of hsCRP, WBC, FIB in MS group were increased obviously (P

To achieve the goal of continuous improvement, measures of multi-link management were adopted for antimicrobial use, including establishing and improving organizational frameworks and rules and regulations, conducting various forms of training for all workers and staff, formulating criteria that were based on the frontier theories and could be easily applied, taking effective measures of intervention, using scientific evaluation methods, and getting timely feedback. The measures have proved to be effective in practice.

The strategies for automatic extraction of key words from medical news were put forward by adding the MeSH terms into the general classification table in combination with the length of MeSH terms and location-weigh-ted MeSH terms.The key words randomly selected from 100 papers reporting medical news on 10 Websites were in-dexed and verified by machine indexing.The extraction accuracy was 0.34 and the recall rate was 0.30, showing that the strategies can be used for automatic extraction of key words from medical news.

The inducible c-myc antisense RNA expression plasmid PGXC expressed in mammalian cells was constructed. PGXC was cotransferred with plasmid pSV2neo which confers resistance to Geneticin (G418) to human promyclocytic leukemia cell line HL60. Following the promotion of c-myc antisense RNA expression with Cd~(2+) the growth rate of transfectant HL_(60)~R-9 was significantly slower than that of the parent cells HL60. Flow cytometric analysis indicated a marked increase in Gl fraction and decrease in S-phase population in the cell cycle of transfectants. The differentiation of cellular morphology and function of HL_(60)~R-9 was induced. HL_(60)~R-9 did not form colonies on soft agar and had reduced or lost the tumorigenicity in nude mice.

Objective To study the therapeutic effects of comprehensive rehabilitation training on cognitive impairment of chronic schizophrenics.Methods 86 inpatients with chronic schizophrenia were randomly assigned to the observation group(n=42)and the control group(n=44).They were studied with the Event-related potential P300 and the Positive and Negative Syndrome Scale(PANSS)before and after comprehensive rehabilitation training.Results Compared with controls,the observation group manifested shorter latency and higher amplitude on Target P3 wave of P300 after treatment(P

After the necessity of using medical news information and the advances in its automatic indexing were analyzed, a novel automatic controlled indexing method of medical news text was put forward. The method intro-duced translated MeSH vocabulary as the main indexing words, merging Chinese commonly used word segmentation dictionary, then calculated word frequency for document text which added split token and sorted it, choose top 5 high-frequency words in MeSH vocabulary indexed document after deleting high-frequency words not in MeSH vo-cabulary.

Objective:To explore the effect of psychological training on self consistency and congruence of army men. Methods:532 army men were tested by Self Consistency and Congruence Scale(SCCS)、EPQ、simplified coping style questionnaire(SCSQ)and SCL-90. Results:There were significant difference in score of SCCS between army men group and norm.There were significant correlation between factor scores of SCCS and scores of EPQ,SCSQ and SCL-90. After psychological training,the study group had higher score in flexibility than that of norm. The study group had higher score in flexibility and positive coping style than control group,and lower scores in P and N of EPQ,total score,obsessive-compulsive,interpersonal sensitivity,anxiety,hostility,paranoid ideation and psychoticism of SCL-90 than control. Conclusion:Self consistency and congruence level of army men were associated with personality, coping style and mental health. The psychological training has effect on balancing personality,facilitating self consistency,improving coping style and the psychological status of army men.

Objective To investigate the precision, trueness, and accuracy of self-developed detection system in clinical chemistry.Methods This was a methodological evaluation.Take serum creatine kinase( CK) for instance, 6 serum sampleswith different leves ( on the upper or lower limit of the reference range or close to the medicine decide levels ( MDLs) , were collected for within-run precision( repeatability) and within-laboratory precision ( intermediate precision ) experiments.5 proficiency testing ( PT ) samples, 5 samples assigned value by reference method, and 40 fresh-frozen serums were measured and compared with reference method for trueness verification.Drawing method evaluation decision chart, calculating total errors and sigma level evaluation experiment based on the CV, bias, and allowed total errors(TEa)were used to evaluate the accuracy performance.The precision, trueness, and accuracy were compared with the quality indicators.Results The within-run precision and within-laboratory precision were less than the highest requirement of Chinese industrial standard.The mean bias was -8.96%, didn′t reachthe required standard (5.5%).After taking corrective actions, all samples but one ( -5.8%) met the required standard. Compared with the reference method, the mean bias on the MDLs was less than TEa.The performance points of the method evaluation decision chart indicated excellence performance.The total errors on MDLs were 14.2%, 10.4% and 7.6%, less than 15%.The sigma levels on MDLs were 5.9, 7.5 and 15, also achieved excellent level. Conclusions The precision, trueness, and accuracy performance of CK measured by self-developed detection system achieved excellent level of the Chinese industry standard, and the same results were found from different evaluation methods.

Routine supervision on hospital infection control was normally fed back on paper-based media,plagued by low efficiency and poor traceability.A feedback process developed with Workflow technology,can loop the entire process ranging from routine supervision to identifying loopholes,to hospital infection and joint development of correctional measures clinically,all the way to implementation of infection control practice and sustained improvement.The closed-loop PDCA cycle management features greater efficiency and traceability in hospital management of its infection control,and builds a quality improvement model featuring close communication between infection control department and clinical departments.
