Objective: To analyze the distribution and related factors of spherical equivalent(SE) anisometropia in school aged children in ethnic minority areas of Yunnan Province, so as to provide a scientific basis for the intervention and control of SE anisometropia. Methods: In October 2021,a total of 1 852 school aged children in three counties/cities(Lijiang City,Dali City,Xishuangbanna) in Yunnan Province were examined by multi stage cluster random sampling method for computer optometry visual acuity examination for non ciliary paralysis and questionnaire survey.Demographic characteristics, ocular biological parameters and SE data were obtained for SE anisometropia. Group comparisons were conducted using Mann-Whitney U test or Kruskal-Wallis H test, and Logistic regression was used to explore the related factors of anisometropia in SE. Results: The prevalence of SE anisometropia among school age children was 23.0%, and the prevalence was higher in girls (24.2%) than that in boys (21.6%). Compared with non anisometropic children, school aged children with SE anisometropia had longer axial length (AL) [24.03 (23.41, 24.76), 23.93 (23.26, 24.61) mm] and corneal curvature radius (CR) [43.42 (42.43, 44.42), 43.14 (42.23, 44.04)mm], SE[-1.75(-2.75,-1.00),-0.94(-2.63,-0.25)D], smaller spherical scope [-1.38(-2.38,-0.75),-0.75(-2.38,0)D], deeper anterior chamber depth(ACD)[3.77(3.62, 3.93), 3.72(3.55, 3.89)mm], and grater differences in AL[0.58(0.32,0.82), 0.13( 0.06 ,0.22)mm], ACD[0.05(0.02,0.08), 0.03(0.01,0.06)mm] and AL/CR[0.01(0.01,0.02), 0.01(0.00,0.01)]( Z =-22.47 to -2.41, all P <0.05). The results of Logistic regression showed that mild myopia( OR =2.74), moderate myopia( OR =3.52), and high myopia( OR =8.92) had a relatively high risk of anisometropia SE in school aged children(all P <0.05). Conclusion The prevalence of SE anisometropia in school aged children in ethnic minority areas of Yunnan Province is relatively high, and the prevalence and degree of anisometropia were closely related to myopia degree and related refractive parameters.

Objective To assess ocular biometric parameters among primary and secondary school students from Naxi,Bai and Han ethnic groups in Yunnan Province.Methods The school-based study was conducted in October 2020.A total of 724 second-,third-and seventh-graders were selected from Dali and Lijiang,where Bai and Naxi ethnic groups inhabit,using a stratified cluster sampling method to receive questionnaire surveys and eye examinations.Non-cycloplegic spherical equivalent(SE),axial length(AL),anterior chamber depth(ACD),corneal radius of curvature(CR),central corneal thickness(CCT),white-to-white(WTW)distance,and the AL/CR ratio were measured.Covariance analysis was used to examine the differences in SE and ocular biometric parameters in terms of ethnicity,sex and grade,while Pearson correlation was used to test the associations among the said indicators.Results There were no significant differences in daily outdoor time,screen time and sleep time among the three ethnic groups regardless of grades(all P＞0.05).The mean CCT of Naxi students was lower than that of Han and Bai students[grade 2 and grade 3:(542.48±39.76)μm vs.(553.81±31.83)μm and(559.27±32.79)μm;grade7:(538.86±34.91)μm vs.(547.41±33.55)μm and(548.26± 32.98)μm,all P＜0.05],while no significant differences were found in the other ocular biometric parameters among the three ethnic groups(all P＞0.05).Among the seventh-graders,the SE,AL and AL/CR ratio of Naxi students were signifi-cantly different from those of Han and Bai students(all P＜0.05).The AL,CR,ACD,CCT,WTW distance,and mean SE were lower in girls than in boys(all P＜0.05).Compared with grade 2 and grade 3,students of grade 7 had longer AL,deeper ACD and thinner CCT(all P＜0.05),while no significant differences were found in CR and WTW distance(all P＞0.05).Correlation analysis showed that the AL/CR ratio was highly correlated with SE(r=-0.78,P＜0.05).Conclu-sion Multiethnic primary and secondary school students may face similar environmental risks.Yet,disparities in ocular biometric parameters caused by ethnicity,sex and age should be noted.

Objective: To explore the related factors of myopia among children and adolescents in Yunnan Province, and to predict and evaluate the influencing factors, so as to provide a scientific theoretical basis for the prevention and control of myopia. Methods: From March 9 to 14, 2023, 848 students from 6 primary and secondary schools in Dali and Lijiang of Yunnan Province were selected by multi stage stratified random cluster sampling method for visual acuity detection and questionnaire survey on myopia related factors. Multivariate Logistic regression analysis was used to establish a Nomogram prediction model for the selected influencing factors. Results: The overall myopia rate of the respondents was 68.3%, the myopia rate of boys (63.4%) was lower than that of girls (72.9%), and the myopia rate of primary school students (46.7%) was lower than that of junior high school students (81.1%), and the difference was statistically significant（ χ 2=8.71, 108.07, P <0.05). Daily eye exercises, activities outside the teaching building during recess, having daily sleep time of 7-9 and >9 h, having both parents without myopia were negatively correlated with the occurrence of myopia in children and adolescents in Yunnan Province ( OR=0.64, 0.63, 0.56, 0.28, 0.48, P < 0.05 ). The reading and writing time after school ≥3 h per day and parents unrestricted time to play video games were positively correlated with myopia ( OR=1.94, 1.78, P <0.05). Based on the influencing factors, a Nomogram prediction model was established to quantitatively evaluate the risk of myopia. The results showed that greater risk for myopia was associated with sleep duration, parental history of myopia, and the time spent reading and writing after school every day. Conclusion Both genetic factors and environmental factors are related to myopia in children and adolescents. The prediction model of nomogram is beneficial for screening high risk factors of myopia and taking corresponding prevention and treatment measures.

Sepsis and septic shock are important clinical problems in critically ill patients, accounting for the first cause of death in intensive care unit (ICU). Therefore, early diagnosis and treatment are particularly important. Recently, genome-wide expression analysis of non-coding RNA in septic patients showed that more than 80% were differentially expressed compared with healthy individuals. These molecules play important roles in biological processes, including innate immunity, mitochondrial function and apoptosis. Therefore, a class of non-coding RNAs such as microRNA (miRNA), long-chain non-coding RNA (lncRNA) and circular non-coding RNA (circRNA) are increasingly recognized as a regulator of various signaling pathways. The potential of regulatory non-coding RNA target to treat sepsis was discussed by studying non-coding RNAs that might serve as molecular markers of sepsis, and its clinical value was evaluated.

GABARAP, a microtuble-associated protein, is identified to interact with GABAA receptor. Anchoring of the GABAA receptor to GABARAP helps to cluster the receptor at the synaptic termini and to mediate fast synaptic transmission. GABARAP may mediate interaction of gephyrin with the GABAA receptor to stabilize clusters by forming multimeric structures. Furthermore, GABARAP and gephyrin may play more of a role in receptor sorting and transport to the cell surface than in anchoring to the cytoplasm, because at inhibitory synapses GABARAP appears to associate with transport vesicles rather than the cell surface. The association of GABARAP with NSF (N-ethylmaleimide sensitive factor), a protein involved in intracellular vesicle transport, supports this hypothesis. We cloned cDNA encoding full-length human GABARAP by nested PCR and inserted it into eukaryon expression vector pcDNA6HA and GST fusion protein expression vector pGEX4T2. The recombinant plasmid pGEX4T2-hGABARAP was transformed into E. coli BL21, from which GST-hGABARAP fusion protein was purified after IPTG induction by affinity chromatography with glutathione Sepharose-4B column. The antiserum against GABARAP was generated by immunizing rabbits with the purified GST-hGABARAP and was purified with GST-hGABARAP coupled NHS-activated Sepherose 4 column. The purified polyclonal antibody was effective for Western blotting and immunostaining. The hGABARAP was located both in the cytoplasm and nucleus with an abundant distribution around the peripheral nucleus.
