Myopia,due to its rapid progression and sever complications,has become an important global public health issue.Although there are numerous reports on myopia progression and its risk factors in university students,longitudinal reports are relatively rare and mainly focused on medical students.Generally,the myopia progression is slow and stable among the university students.More myopic initial refraction,more near distance work and less outdoor activity are the clear risk factors for myopia progression in this population.This review summarized the reports on myopia progression and its risk factors,such as age,sex,refractive status,near distance work or outdoor activity in university students.

Objective To investigate the relationship among the D-dimer,C-reactive protein and left atrial diameter in the patients with atrial fibrillation(AF). Methods 53 AF patients were selected,the control group consisted of 32 cases of sinus rhythm(SR). The levels of D-dimer, CRP and LAD in AF group were compared with each other, and with those in the control group. Correlation analysis between D-dimer, CRP and LAD were made.Results D-dimer,CUP and LAD in AF group were significantly different from those in SR group. D-dimer and CRP in persistent AF and permanent AF differed significantly from that in SR and paraxymal AF. LAD in the group of persistent AF differed from that in SR group. LAD in permanent AF was significantly different from that in paraxymal AF and SR. Positive linear correlations were found between D-dimer, CRP and LAD in AF (r=0.376; 0.33).Conclusion Hypercoagulable state existsed in AF; the elevation of CRP should be the result and related to persistence time of AF. Positive correlation existsed between LAD and hypercoagulable state and inflammatory reaction.

OBJECTIVE:To evaluate therapuetic efficacy and toxic reaction of 2 therapuetic regimens for 56 cases of bone me-tastasis of cervical cancer. METHODS:56 cases of bone metastasis of cervical cancer with complete information were collected ret-rospectively and randomly divided into radiochemotherapy group(31 cases)and diphosphonate group(25 cases). Radiochemothera-py group was given radiotherapy,chemotherapy and diphosphonate;diphosphonate group was given palliative symptomatic treat-ment of diphosphonate;a treatment course lasted for 3-4 weeks,and both groups received 3 courses of treatment. Average survival time,survival quality and toxic reaction were comparison in 2 groups. RESULTS:After bone metastasis of cervical cancer,the av-erage survival time of radiochemotherapy group was 17 months (95%CI:9.1-24.9),and that of diphosphonate group was 19 months (95%CI:2.4-35.6);3 years later,the survival rate of radiochemotherapy group was 16.1%,and that of diphosphonate group was 16.0%,there was no statistical significance(P=0.820). To compared KPS after 3 treatment courses,the improvement rate of radiochemotherapy group(22.6%)was significantly lower than that of diphosphonate group(40.0%),with statistical signif-icance (χ2=4.36,P<0.05). Toxic reaction of radiochemotherapy group was more significant than that of diphosphonate group. CONCLUSIONS:Diphosphonate has little effect on survial quality and slight toxic reaction. It is worthy of spreading in some pa-tients with advanced,elderly and reccurred bone metastasis of cervical cancer.

Objective To observe the curative effect of nourishing the lung and strengthening the spleen and nourishing the lung to the acute exacerbation of chronic obstructive pulmonary disease with malnutrition.MethodsProspective selection 120 cases were diagnosed as AECOPD patients with malnutrition of the Department of respiratory medicine from June 2015 to August 2016,Were randomly divided into EN group and combination group, 60 cases in each group, EN group with high fat and low sugar EN liquid Omega and ω3 Yu You Zhi Fang Ru Zhu She Ye and N(2)-L-alanyl-L-glutamine for Injection, Combined group in the EN group based on the added benefits of lung spleen, compared the Nutritional status and immune function between the two groups.ResultsTwo groups of patients were successfully completed 14d treatment, After treatment, BMI, TSF, MAMC, TP, ALB, PA, HGB, TFN, NB levels were significantly higher than those before treatment (P<0.05);Combined group after treatment, the level of each index was significantly higher than the EN group (P<0.05).WBC, hs-CRP, IL-6, TNF-α levels in the two groups were significantly lower than before treatment, TLC, IgA, and IgG levels were significantly higher than before treatment (P<0.05);the combination group WBC, hs-CRP, IL-6, TNF-αlevel lower than the EN group, TLC, IgA, IgG level higher than the EN group (P<0.05).ConclusionBenefit lung and spleen strengthening traditional Chinese medicine combined with enteral nutrition can improve the nutritional status, respiratory function and immune function in patients with acute exacerbation of chronic obstructive pulmonary disease, and has high application value.

Objective To investigate the inhibitive effect of Konjac polysaccharide(KP) on intestinal absorption function of mice and its mechanism.Method Mice were divided into normal control(N),high fat(HF),and high,middle,low dose KP(KPH,KPM,KPL) treated groups.Intestinal mucosa Na+-K+-ATPase activity was determined by UV spectrophotometry,blood glucose was determined by fast meter after twenty days.Body weight,fecal wet weight and dry weight were also examined.Results Na+-K+-ATPase activity of HF and KPH groups were 16.2?1.48 and 11.2?1.10 ?mol Pi/(mg prot?h),respectively.Body weight and postprandial blood glucose were 34.3?2.07 g,7.5?1.15 mmol/L and 28.1?1.95g,4.8?0.73 mmol/L,respectively.The differences between two groups were significant(P

Objective To study the feature of the etiology of pediatric syncope by cases study,and to discuss the feasibility on identification between the cardiac and neurally-mediated syncope with its inducements and symptoms.Methods One hundred and eleven patients were etiologically classified by standard diagnostic procedure to summarize the inducements,presymptoms and symptoms.The data about cardiac and neurally-mediated syncope were statistically treated to find their characteristic manifestation.Results Among these,60.4% was non-cardiovascular syncope,18.9% was postural hypotension,18.0% was vasovagal syncope and 9% was cardiac syncope.Most of them were non-cardiac syncope and neurally-mediated syncope was on the top,while cardiac syncope was rare in children.Prolonged standing and nausea was the feature of the neurally-mediated syncope,and the cardiac syncope is associated with physical exercise.Conclusions Most pediatric inpatients were non-cardiovascular syncope in which neurally-mediated syncope is first on the list.The movement-related syncope is the feature of the cardiac syncope.The prolonged standing and nausea are due to neurally-mediated syncope.

Objective To study the value of St George's respiratory questionaire(SGRQ)in evaluating the life quality of community patients with COPD.Methods The SGRQ score,PEF% were collected from 35 patient with COPD.Paired t test was performed to evaluate the sensitivity of SGRQ to changes of disease severity.Correla- tion coefficients were calculated to evaluate the validity.Results Three parts of the SGRQ score and the total score were significantly correlated with the changes of SGRQ(P＜0.001),SGRQ was more sensitive than PEF in evalu- ating the changes of disease severity.The three part of the scale and the total scale were significantly correlated with PEF%.Conclusion SGRQ is a valid,sensitive and feasible method in measuring the quality of life in community patients with COPD.
