Objective To study the correlation of peritumor brain edema and the proliferation of meningiomas.Methods Forty-six patients who underwent resection of meningioma were divided into four groups(no,mild,middle and severe PTBE) according to CT.Proliferating cell nuclear antigen(PCNA) was detected with immunohistochemistry.Results There were 18 cases mild PTBE[PCNA LI (2.83?1.57)],10 cases middle PTBE[PCNA LI (3.14?2.04)] and 5 cases severe PTBE[PCNA LI (4.13?2.43)] in forty-six patients.PTBE was related to meningioma PCNA LI significant.Conclusion PTBE of meningioma relates with tumor cell proliferation.

ObjectiveTo investigate the clinical efficacy of Jin’s eye three-needle acupuncture as main therapy for acquired paralytic strabismus.MethodSeventy patients with acquired paralytic strabismus were randomly allocated to acupuncture and Western medication groups. Both groups of enrolled patients took prednisone,methycobal, vitamin B1and vitamin B12. In addition, theacupuncture group received Jin’s eye three-needle acupuncture as main therapy. The clinical therapeutic effects and adverse reactions were observed after four and eight weeks of treatment.ResultThe total efficacy rate was 75.0% in the acupuncture group and 51.6% in the Western medication group after four weeks of treatment and 90.6% in the acupuncture group and 77.4% in the Western medication group after eight weeks of treatment. There were statistically significant differences between the two groups (P<0.05). Patients in the acupuncture group occasionally had acupuncture syncope and local blood stasis. Both groups had no special discomforts.ConclusionJin’s eye three-needle acupuncture has a quick and definite therapeutic effect on acquired paralytic strabismus.

Objective: To investigate the refractive status of children and adolescents aged 4-18 years in Chengdu, and to analyze the epidemiological characteristics of refractive parameters. Methods: A cross sectional survey was conducted among 82 024 children and adolescents aged 4-18 years in Gaoxin District of Chengdu from August to September 2021. The prevalence of screening myopia, low vision rate, high myopia rate, refractive status and axial development were analyzed. Results: The prevalence of screening myopia in students aged 4-18 years was 40.42%(33 158/82 024). Low myopia was 24.51%(20 108/82 024), moderate myopia was 13.05%(10 703/82 024) and high myopia was 2.86%(2 347/82 024). The prevalence of screening myopia was 1.81% (233/12 848) in kindergarten, 34.44%(17 095/49 644) in primary school, 79.73%(9 738/12 214) in junior high school and 83.25% (6 092/7 318) in senior high school. The rate of visual impairment increased by year from the age of 4, and the rate of myopia increased most rapidly from 6 to 15 years old, the prevalenct of high myopia was compared between adjacent age groups: there were statistical differences between 9-15 years old were more likely to be nearsighted than boys( P <0.035 7). Significant differences in screening myopia between 5- and 7-17 year old groups,and in boys and girls.The median total diopter was 0.40 D at the age of 4 and developed to -2.90 D at the age of 18 . The diopter of girls aged 8-15 years was higher than that of boys, and there was statistical significance( Z=-2.53, -4.09, -5.67, -8.64, -5.56, -4.97, -2.52, -2.14, P <0.05). The axial length gradually increased with age, with the mean value of (22.31±0.59) mm at 4 years old and (24.91±1.00) mm at 18 years old. The mean corneal curvature did not change with age (43.19±1.47)D. Conclusion 6-15 years old is a especially critical period for myopia development. More efforts need to be taken to decrease the prevalence of myopia before 6 years old. Prevention of the development of high myopia should start before the age of 10. The prevalence of myopia in girls is higher than that in boys, more prevention and control of myopia should focus on girls.
