AIM: To analyze the amblyopia morbidity status of young children in Shaanxi city of Xi'an Province, and to explore the related risk factors. ·METHODS: Totally 10268 children between 3-6 years old were screened in 8 kindergartens in our city from March 2012 to April 2016 via a simple non-repeated sampling method, and sight, eye position, eye movement examination were mainly implemented;10g/L atropine mydriatic optometry was taken to detect eye fundus examination, and to eliminate organic lesion. There were 528 amblyopic children were set as the observation group, 500 healthy children who were treated in our hospital at the same time were set as the control group. Single factor analysis and multiple logistic regression analysis were carried out for children with amblyopia. ·RESULTS:In a survey, the incidence rate of amblyopia among young children in Shaanxi Xi'an was 5. 14%. Ametropic amblyopia accounted for the highest proportion (61. 4%), and lesion extent was usually mild to moderate, ametropic amblyopia accounted for 24. 1%, which was inferior to that was the strabismus accounted as 12. 9%, rare were form deprivation amblyopia accounted for 1. 7%. General data analysis showed that, there were significant differences between the two groups in maternal gestational age, gestational weeks and times of pregnancy, smoking history of parents, family genetic history of myopia (P<0. 05). Multivariate logistic regression analysis showed that pregnancy when old, mother's smoking history, family genetic history of myopia and short gestational weeks were risk factors for amblyopia in young children (P<0. 05). · CONCLUSION: There is a certain oneset risk of amblyopia in young children in Shaanxi Xi'an. Attention should be paid to educate eye care knowledge, organize regular visual screening, ensure early detection, early diagnosis, early treatment.

MethodsFlow cytometry was used to analyze CD28 and B7 molecules expressed on T lymphocytes and primary breast cancer cells respectively. Results CD28 positive T lymphocytes in breast cancer patients was lower than that in control group (t=2.879,P

Objective To investigate the feasibility and efficacy of posterior retroperitoneoscopic adrenalectomy (PRA).Methods From September 2013 to September 2015,the clinical data of 35 patients who underwent posterior retroperitoneoscopic adrenalectomy were reviewed.There were 14 males and 21 females,aged 15-70 years,with the average of 45.8 years.Preoperative CT scan showed 19 adrenal tumors in the left side,16 in the right side,and one case with the left adrenal adenoma combining with right renal cyst.Tumor diameter is between 10 ~ 60mm,with the average of 31mam.Twenty-two cases were diagnosed as primary aldosteronism,4 pheochromocytoma,and 9 non-functional adrenal tumor.The posterior retroperitoneoscopic adrenalectomy were performed in all of the cases,which are under general anesthesia with tracheal intubation and prone position with hip joints and knee joints flexion of 90.Results Thirty-five operations were successfully completed via the posterior approach demonstrating clear anatomical layers.The operation time was 38-138min(mean 70 min),the drainage tube indwelling duration was l-Sd(average 2d),and the hospital stay was 2-6d (average 4d).Total costs of hospitalization were 14 789-31 992 yuan RMB,with an average of 21 239 yuan RMB.No complications occurred during the perioperative period.The average follow-up was 11 months,and no complications such as tumor recurrence occured.Conclusions Retroperitoneoscopic adrenalectomy provided clear anatomical views.It could be a safe and effective operation for the treatment of adrenal tumors.

Objective To explore the relationship between apolipoprotein E ( ApoE ) genotype and diabetic nephropathy (DN) in Chinese Han population of Guangdong province. Methods 63 cases of DN patients were selected as group A; 57 diabetes patients without complications as group B; 55 healthy persons as group C. ApoE genotype of all objects were measured. Results ApoE2 in the group A was the highest, while the differences in other groups were not obvious. Detection of ApoE3 and ApoE4 was not obvious in three groups. The Level of triglyceride (TG) was highest inε2 group, and the level of total cholesterol (TC) and low density lipoprotein LDL-C were highest in ε4 groups. Conclusions In Chinese Han population of Guangdong province , ApoE gene polymorphism and DN are closely interrelated , and the occurrence ofε2 is proportionate to DN.

AIM:To explore and compare effect of coaxial micro-incision phacoemulsification and standard coaxial phacoemulsification in the treatment of cataract.
METHODS:A total of 88 patients(88 eyes) with senile cataract who underwent selective cataract ultrasonic emulsification resorption combined with intraocular lens implantation in the hospital from Aug. 2013 and Aug. 2015 were selected, they were divided randomly into the control group ( 44 cases, 38 cases completed, 6 cases dropped out ) and the observation group ( 44 cases, 40 cases completed, 4 cases dropped out ) . The control group received standard coaxial 3. 0mm small incision phacoemulsification, the observation group received coaxial 1. 8mm micro-incision phacoemulsification. All patients were combined with intraocular lens implantation. Intraoperative effective ultrasonic time, cumulative release energy, best corrected visual acuity before and after surgery in the two groups were recorded, corneal endothelium cell population, incision corneal thickness, percentage of cornea hexagon cell, corneal astigmatism changes before the operation, 1d, 7d, 30d after the operation were compared.
RESULTS: There was no significant difference in intraoperative effective ultrasonic time, cumulative release energy in the two groups(P>0. 05). There was no significant difference in postoperative best corrected visual acuity between the two groups(P>0. 05). Corneal endothelium cell population, percentage of cornea hexagon cell 1d, 7d, 30d after the operation in the two groups were significantly decreased compared with those before the treatment ( P < 0. 05 ), but there was no significant difference in the two groups ( P > 0. 05 ). Incision corneal thickness 30d after the operation in the observation group was significantly lower than the control group(P<0. 05). Degree of corneal astigmatism in the observation group 1d, 7d, and 30d after the operation were significantly lower than the control group (P<0. 05).
CONCLUSION: Coaxial micro - incision phacoemulsification and standard coaxial phacoemulsification can improve visual acuity of cataract patients, but the former can reduce degree of corneal astigmatism.
