Objective In this study,patients with idiopathic intracranial hypertension(IIH)were selected as a model for spaceflight-associated neuro-ocular syndrome(SANS)to conduct an eye movement manipulation intervention experiment.The aim was to explore whether eye movements have an effect on reducing the subarachnoid space around the optic nerve.Methods Twenty-three patients with IIH who met the inclusion criteria were subjected to history taking,collection of basic systemic data including age,height,weight,and blood pressure,and baseline data collection including intraocular pressure(prone)and transorbital ultrasound optic nerve sheath complex image acquisition.The subjects were then subjected to the eye movements intervention and IOP(prone)and transorbital ultrasound optic nerve sheath complex image acquisition were measured at 10 minutes,30 minutes and again 3 days after the intervention.Results The study enrolled 23 subjects with an average age of(29.58±11.25)years and a mean BMI of(28.56±6.3)kg/m2.The average cerebrospinal fluid pressure through lumbar puncture was(310.25±20.78)mmH2O.There were no significant changes in intraocular pressure at various time points before and after the eye movement exercises(P=1.000).Similarly,there were no significant changes in the diameter of the optic nerve at 3 mm and 5 mm posterior to the globe(P=1.000).However,the diameter of the optic nerve sheath at 5 mm posterior to the globe,as well as the width of the subarachnoid space of the optic nerve at 3 mm and 5 mm posterior to the globe,and the area of the subarachnoid space of the optic nerve from 3 mm to 5 mm posterior to the globe,all decreased significantly after performing eye movement exercises for 10 minutes and 30 minutes.These measures returned to baseline levels after three days of eye movement exercises,with significant differences observed across time points(P<0.05).Specifically,compared to baseline values,the diameter of the optic nerve sheath at 5 mm posterior to the globe decreased by 0.33 mm(95%CI:0.034-0.624,P=0.02)after performing 30 minutes of eye movement exercises.Additionally,the width of the subarachnoid space of the optic nerve at 3 mm and 5 mm posterior to the globe decreased by 0.2 mm(95%CI:?0.037-0.452,P=0.034)and 0.29 mm(95%CI:?0.265-0.344,P=0.01),respectively.Finally,the area of the subarachnoid space of the optic nerve from 3 mm to 5 mm posterior to the globe decreased by 0.21 mm2(95%CI:0.155-0.762,P=0.02).Conclusion This study initially proposes an eye movement manipulation method(eye movement exercise)that can reduce the subarachnoid space gap of the optic nerve posterior to the globe,including the direction,duration,rhythm,and frequency of eye movements.It was found that regular eye movements for a certain period of time can deform the optic nerve sheath,compress the subarachnoid space of the optic nerve posterior to the globe,and narrow its gap.As the duration and frequency of eye movement exercises increase,the width or area of the subarachnoid space of the optic nerve decreases more significantly.However,eye movement exercises cannot maintain the deformation of the optic nerve sheath for a long time,and after a certain period of time,the gap of the optic nerve sheath returns to baseline levels.

Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

Objective To investigate the relationship between the vaginal microecology and CC chemokine ligand 28(CCL28)expression levels in the vaginal lavage fluid of patients with persistent high-risk human papillomavirus(HR-HPV)infection.Methods A total of 132 patients with HR-HPV infection at Tangshan Maternal and Child Health Hospital from April 2021 to April 2023 were selected as study subjects.Patients with HR-HPV infection were categorized into the single infection group and the persistent infection group according to the review results.The CCL28 and vaginal microecological indicators of the two groups were compared.Logistic regression was used to analyze the risk factors for persistent HR-HPV infection.The dose-response relationship between CCL28 and persistent HR-HPV infection was analyzed by fitting restricted cubic splines with logistic regression.Spearman and multiple linear regression were used to analyze the relationship between CCL28 and vaginal microecological indicators.Results After the re-examination of patients,there were 84(63.64％)cases of single infection and 48(36.36％)cases of persistent infection.The percentage of colony density grade Ⅰ(54.17％vs 16.67％),colony diversity grade Ⅰ(47.92％),pH＞4.5(47.92％),hydrogen peroxide positivity(54.17％),and vaginal microecological imbalance(66.67％),and the level of CCL28[83.63(77.11,99.62)ng/L]in the persistent infection group were higher than those of the single infection group[16.76％,21.43％,15.48％,30.95％,41.67％,71.11(58.12,82.16)ng/L],and the differences were statistically significant(x2/Z=5.064～20.338,all P＜0.05).Logistic regression analysis showed that colony density grade Ⅰ(OR=3.556,95％CI:1.241～10.194,P=0.018),PH＞4.5(OR=4.366,95％CI:1.164～16.380,P=0.029),and high CCL28 levels(OR=1.048,95％CI:1.018～1.080,P=0.002)were independent risk factors for persistent infection in HR-HPV-infected patients.Logistic regression fitting restricted cubic splines showed a linear relationship between CCL28 and persistent HR-HPV infection(nonlinear test x2=0.61,P=0.437).Spearman correlation analysis results showed that CCL28 was positively correlated with age(r=0.205,P=0.018),colony density(r=0.429,P＜0.001),colony diversity(r=0.389,P＜0.001),pH(r=0.357,P＜0.00l),hydrogen peroxide(r=0.409,P＜0.001),leukocyte esterase(r=0.392,P＜0.00l),and vaginal microecology(r=0.473,P＜0.001).Linear regression analysis showed that colony density(β=12.295,P=0.003)and colony diversity(β=9.196,P=0.032)were independently associated with CCL28.Conclusion Colony density and colony diversity were independently correlated with CCL28.Colony density grade Ⅰ,pH＞4.5,and high CCL28 levels suggest an increased risk of persistent infection in patients with HR-HPV infection.

Objective: Based on observational, longitudinal and intervention study of common diseases among students in Jiangsu Province, this paper presents the current progress of two year follow up of myopia cohort regarding the association between growth parameters with progression of myopia among children and adolescents in areas with rapid economic growth. Methods: This survey adopted the stratified cluster sampling method for school selection. The full automatic computer optometry (TOPCON RM800) was used to track myopia related parameters for all participants from 2019 to 2020 under the condition of mydriasis (compound topicamide eye drops). Relationship between growth parameters of children and adolescents and the incidence and progression of myopia was analyzed by using Cox regression multiple statistical model. Results: The myopia rates of students from grade 1 to grade 3 in 2019 were 5.4%, 21.5% and 37.3% respectively. After one year, the myopia rates of all school stages increased to 25.3%, 43.3% and 58.1% respectively( χ 2=53.59, 49.63, 32.52, P <0.01). The mean diopter of right eye and left eye after mydriasis were ( 0.30± 1.24/0.39±1.26)D in 2019 and (-0.33±1.54/-0.19±1.55)D in 2020, respectively based on Cox multiple regression results, age ( HR =1.21, 95% CI =1.09-1.34), naked eye vision ( HR =0.08, 95% CI =0.07-0.11), height ( HR =0.98, 95% CI =0.97-0.99) showed a strong correlation with the incidence and progression of myopia( P <0.05). Conclusion Myopia is growing rapidly in the central region of Jiangsu Province. It is suggested that diopter, axial length, naked eye vision, age, height and other indicators should be included in the refractive archives of children and adolescents in the region.

Objective: To investigate the prevalence of reproductive system diseases among female workers in a city and related occupational influencing factors. Methods: From June to September, 2016, a cross-sectional survey was used to select 9 944 female workers from six districts of Beijing and then a face-to-face questionnaire survey was performed. Univariate analysis using chi-square test and multivariate logistic regression analysis were used to investigate the risk factors for reproductive system diseases. Results: The age of 9944 female workers ranged from 18 to 65 years (mean 35.53±9.52 years) , and among them, 7 351 (73.92%) were married. The overall prevalence rate of reproductive system diseases among these 9944 female workers during the past three months was 28.29%, and the prevalence rates of hyperplasia of mammary glands, vaginitis, and hysteromyoma were 15.54%, 11.25%, and 6.77%, respectively. After adjustment for age, marital status, education level, and annual family income, the multivariate logistic regression analysis showed that frequent overtime work (odds ratio[OR]=1.119, 95% confidence interval[CI]: 1.070-1.343) , frequent night shifts (OR=1.198, 95%CI: 1.054-1.361) , standing for a long time (OR=1.197, 95%CI: 1.063-1.347) , sitting for a long time (OR=1.327, 95%CI: 1.191-1.479) , heavy workload (OR=1.429, 95%CI: 1.262-1.615) , exposure to lead (OR=1.696, 95%CI: 1.307-2.201) , exposure to mercury (OR=1.452, 95%CI: 1.086-1.940) , and exposure to ionizing radiation (OR=1.679, 95%CI: 1.424-1.980) were associated with reproductive system diseases. Conclusion The prevalence of reproductive system diseases among female workers in Beijing is not optimistic. Reproductive system diseases are associated with frequent overtime work, frequent night shifts, standing for a long time, sitting for a long time, heavy workload, and exposure to lead, mercury, and ionizing radiation.

Objective To investigate the predisposing locations of active hemorrhage in patients with esophageal variceal bleeding. Methods Data of 823 patients with acute esophageal and gastric variceal hemorrhage receiving emergency gastroscopy diagnosed from January 2003 to December 2013 were retrospectively studied. The location and site of active hemorrhage or stigmata were analyzed and its relationship with active hemorrhage was discussed. Results A total of 372(45. 2%,372/823) patients with active bleeding and stigmata were found under emergency endoscopy. Among 372 patients, 190 got accurate hemorrhage and stigmata location and site description. Bleeding or stigmata in 58(30. 5%) patients was 28-32 cm from incisor in group A, and that in 132 (69. 5%) patients was more than 35 cm in group B ( χ2＝57. 642, P＜0. 000 1). In 190 cases, the proportion of bleeding or stigmata at 3:00 point was the highest (37%,70/132), followed by those at 12:00 point(30%,58/132),6:00 point(24%,45/132),and 9:00 point (9%,17/132). The change trend of the percentage of each point in group A and group B was the same as that in all cases. The percentage of almost all points in group B was significantly higher than that in group A except that at 9:00 point ( P＜0. 000 1).Conclusion Esophageal variceal bleeding in cirrhosis is more common at 3:00 point, 6:00 point and 12:00 point of esophagus, and the high risk area is 35 cm below the incisors.

Objective To evaluate the clinical effect of balloon closure combined with endoscopic therapy on spontaneous gastrorenal shunt ( SGRS ) and spontaneous splenorenal shunt ( SSRS ) . Methods The data of 33 patients of gastric varices with SGRS or SSRS diagnosed in the Chinese PLA General Hospital between January 2009 and February 2016 were collected. All patients were treated with the balloon retrograde distributary channel blocking technique and endoscopic histoacryl injection. Patients' clinical data, complications and effect of endoscopic therapy were retrospectively analyzed. Results In the 33 patients of gastric varices, gastrorenal shunt was found in 28 ( 84. 8%) cases and splenorenal shunt was found in 5 ( 15. 2%) cases. After the balloon blocking technique, 24 cases ( 72. 7%) were occluded successfully. Four cases failed in occlusion of SSRS due to tortuosity. There were no postoperative ectopic embolism, infection, hepatic encephalopathy, liver function deterioration, and other complication. Early latex varices were found in 21 cases after three months follow-up. Conclusion The balloon blocking technique combined with tissue adhesive injection could safely and effectively avoid the risk of ectopic embolism and plays an important role in the treatment of gastric varices in merger portasystemic shunt.

Objective To evaluate the safety and efficacy of endoscopic treatment in patients with primary hepatic carcinoma and gastroesophageal variceal hemorrhage. Methods Thirty cases of hepatic carcinoma with gastroesophageal variceal hemorrhage diagnosed with gastroscopy between January 2008 and June 2015 in Chinese PLA General Hospital and Hainan branch were included. Patients′ clinical data, complications and therapeutic effects of endoscopy were retrospectively analyzed. Results All patients underwent endoscopy successfully. No recurrent bleeding was found in any case after treatment. Eight cases of varicosis nearly disappeared. Six?month follow?up showed three cases of gastrointestinal bleeding, one case of death of bleeding, and no recurrence hemorrhage in 27 others. Conclusion Endoscopic treatment could safely and effectively control the primary liver cancer combined with gastroesophageal variceal hemorrhage, hence may provide opportunity for further treatment of liver cancer.
