Objective To explore the mitochondrial dysfunction in glaucoma-related optic nerve injury and its effect on the apoptosis of retinal ganglion cells(RGCs).Methods The RGC-5 cells were incubated under elevated pressure(70 mmHg,1 kPa=7.5 mmHg)on the basis of standard atmospheric pressure(100 kPa)for 12 h,24 h,and 48 h,respective-ly.The RGC-5 cells cultured under the standard atmospheric pressure were selected as the blank group.The apoptosis of RGC-5 cells was detected through Annexin V/PI staining.The mitochondrial membrane potential(MMP)and reactive oxy-gen species(ROS)level were measured using the JC-1 staining and DCFH-DA fluorescent probe.The expression levels of B cell lymphoma-2(BCL-2)protein,BCL-2-associated X(BAX)protein,cleaved Caspase-3,and cytochrome C(CytC)pro-tein were detected using Western blot.Results Compared with the blank group,the MMP in the 12 h,24 h and 48 h groups significantly decreased(all P＜0.05).Compared with the blank group,the cell apoptosis and ROS level in the 24 h and 48 h groups significantly increased(all P＜0.05),while there was no statistically significant difference in the cell apop-tosis and ROS level between the 12 h group and the blank group(both P＞0.05).Compared with the blank group,the rela-tive expression levels of cleaved Caspase-3 and BAX protein in the 24 h and 48 h groups significantly increased(all P＜0.05),while the relative expression levels of cleaved Caspase-3 and BAX protein in the 12 h group showed no significant difference(both P＞0.05).Compared with the blank group,the relative expression level of BCL-2 protein in the 12 h,24 h and 48 h groups decreased,and the differences were statistically significant(all P＜0.05).Compared with the blank group,the relative expression level of Cyt C protein in the 48 h group significantly increased(P＜0.05),while the relative expression level of Cyt C protein in the 12 h and 24 h groups showed no significant difference(both P＞0.05).Conclu-sion After culture at 70 mmHg pressure,RGC-5 cells show increased apoptosis and mitochondrial dysfunction.The mito-chondrial damage at the early stage of stress injury may be closely related to exogenous apoptosis pathways.

Objective To observe the clinical efficacy of Jiangshabanxia nano-paste on nausea and vomiting in end-stage patients and its effect on the quality-of-life (QOL) in cancer patients. Methods 120 end-stage patients with nausea and vomiting symptoms above grade III were randomly divided into observation group and control group. They were treated with Jiangshabanxia nano-paste and placebo paste respectively. The paste patch was changed every 24 hours and used continuously for 7 days. The nausea and vomiting symptom score, the quality-of-life measurement score and KPS score of cancer patients in the two groups were observed to evaluate the curative effect. Results After 7 days of treatment, the symptom scores of nausea and vomiting in the observation group decreased significantly, the KPS score of the observation group increased, and the effective rate was higher than that in the control group. The score of QOL measurement showed that after treatment, the score of main symptom areas and other symptom areas (except external dyspnea, diarrhea and economic difficulties) in the observation group decreased, and the score of overall health area increased. After treatment, the score of main symptom areas and other symptom areas (except external dyspnea, diarrhea and economic difficulties) in the observation group was lower than that in the control group, and the scores of overall health area in the observation group were higher than those in the control group. Conclusion Jiangshabanxia nano-paste has a good clinical efficacy nausea and vomiting in end-stage patients, it also can improve the quality of life end-stage cancer patients.

Objective:To observe the effects of blue light intervention on the development of optical defocus-induced myopia in guinea pigs and investigate its underlying mechanisms.Methods:Forty-eight normal-grade two-week-old tricolor guinea pigs were randomly divided into a blue light group and a white light group, with 24 animals in each group.The right eye of guinea pigs was fitted with a -5.00 D lens to establish an optical defocus model as the experimental eye, while the left eye served as the control without any covering.Before the experiment and after 8-week intervention, the refractive power of guinea pigs was measured by streak retinoscopy.The anterior chamber depth, lens thickness, and axial length were measured by A-scan ultrasonography.Corneal curvature radius was determined using a keratometer.After 8-week intervention, the guinea pigs were euthanized through overanesthesia, and the right eyeballs were enucleated and the retinas were isolated.The density of S and M cone cells of the guinea pig retinal sections were observed via immunofluorescence staining.The expression of retinal retinoic acid was assessed by high-performance liquid chromatography.The expressions of retinoic acid receptor (RAR-β) in the retina and matrix metalloproteinase-2 (MMP-2), tissue inhibitor of metalloproteinase-2 (TIMP-2), and type Ⅰ collagen in the sclera were detected by real-time fluorescence quantitative PCR.Changes in scleral thickness were observed through hematoxylin-eosin staining.The use and care of the animals complied with Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.The study protocol was approved by the Ethics Committee of Eye and ENT Hospital of Fudan University (No.2022ETKLD10032).Results:After 8 weeks of intervention, guinea pigs in the blue light group showed (0.63±0.12)D of relative hyperopia and a deceleration of axial elongation by (0.08±0.00)mm compared with the white light group in the right eye.In the left eye, guinea pigs in the blue light group showed (0.42±0.09)D of relative hyperopia and a deceleration of axial elongation by (0.08±0.00)mm compared with the white light group.The guinea pigs in blue light group showed (1.52±0.09)D of myopia in the right eye compared with the left eye, with an increase in axial elongation of (0.06±0.00)mm.The guinea pigs in white light group showed (1.66±0.07)D of myopia in the right eye compared with the left eye, with an increase in axial elongation of (0.13±0.00)mm, and the differences were statistically significant (all at P<0.05). The density of M cone cells was lower and density of S cone cells was higher in the blue light group in the dorsal and ventral sides of the retinal sections compared with the white light group, showing statistically significant differences ( t=32.33, 52.23, 42.09, 25.02; all at P<0.05). The deceleration of myopia progression in the blue light group was strongly positively correlated with the increase in S cone cell density on the ventral side ( r=0.95, P<0.01). The expression levels of retinoic acid, RAR-β, and MMP-2 were decreased, and expression levels of TIMP-2 and type Ⅰ collagen were increased in blue light group compared with the white light group, showing statistically significant differences ( t=18.73, 7.45, 3.72, 6.19, 9.03; all at P<0.05). The scleral thickness in the blue light group was (125.0±7.8)μm, which was significantly thicker than (102.0±6.3)μm in the white light group ( t=26.93, P<0.05). Conclusions:Blue light intervention can inhibit the progression of defocus-induced myopia in guinea pigs.Refractive power changes in guinea pigs may be influenced by alterations in retinal cone cell density, retinoic acid expression, and scleral collagen expression.

As society ages and the number of people with low vision grows, the need for low vision rehabilitation for patients is increasing.The electronic head-mounted display (HMD) aids is a new type of low vision aids, which can be divided into different types such as monocular, binocular, virtual reality (VR) and augmented reality (AR). The performance of electronic HMD visual aids is important in their development and evaluation, including improved illumination, contrast ratio, resolution, and expanded vision field.VR devices have higher resolution and richer image modes, which can effectively improve central vision acuity and contrast sensitivity, and are more suitable for static applications.AR devices do not block the patients' habitual field of vision and do not destroy stereoscopic vision, which are more suitable for dynamic applications.With the development of VR and AR display technology in recent years, electronic HMD aids have made great progress in functionality, portability and aesthetics.In most of the research, the application population of electronic HMD aids are patients with low central vision.Electronic HMD aids can improve their visual acuity, contrast sensitivity and reading ability by enlarging pictures, improving illumination and contrast ratio and enhancing contour.For patients with peripheral visual field defects, electronic HMD aids, especially AR devices, can significantly expand their peripheral visual field without blocking original visual field.However, the improvement of electronic HMD aids on daily activities, especially athletic ability, needs further research.This article summarized the types, performance and application progress of electronic HMD aids in patients with low vision.

Drug optimization, which improves drug potency/specificity by structure‒activity relationship (SAR) and drug-like properties, is rigorously performed to select drug candidates for clinical trials. However, the current drug optimization may overlook the structure‒tissue exposure/selectivity-relationship (STR) in disease-targeted tissues vs. normal tissues, which may mislead the drug candidate selection and impact the balance of clinical efficacy/toxicity. In this study, we investigated the STR in correlation with observed clinical efficacy/toxicity using seven selective estrogen receptor modulators (SERMs) that have similar structures, same molecular target, and similar/different pharmacokinetics. The results showed that drug's plasma exposure was not correlated with drug's exposures in the target tissues (tumor, fat pad, bone, uterus), while tissue exposure/selectivity of SERMs was correlated with clinical efficacy/safety. Slight structure modifications of four SERMs did not change drug's plasma exposure but altered drug's tissue exposure/selectivity. Seven SERMs with high protein binding showed higher accumulation in tumors compared to surrounding normal tissues, which is likely due to tumor EPR effect of protein-bound drugs. These suggest that STR alters drug's tissue exposure/selectivity in disease-targeted tissues vs. normal tissues impacting clinical efficacy/toxicity. Drug optimization needs to balance the SAR and STR in selecting drug candidate for clinical trial to improve success of clinical drug development.

Patients with advanced cancer are often accompanied by a variety of symptoms due to disease or treatment,and it is necessary to choose a scientific assessment tool to assess and manage these symptoms. The Edmonton symptom assessment scale (ESAS)is a brief,easy to complete,and comprehensive assessment tool for the common symptoms of patients with advanced cancer. ESAS has been translated into many languages and it is widely used in many countries. In the course of using,the structure and contents of the original scale are adjusted,and the ESAS is more perfect,besides,its reliability and validity are validated,and it is used in the research of evaluation by others.

Objective To analyze the association of miR-326 mRNA expression level on regulatory T cells between clinical manifestations of patients with systemic lupus erythematosus (SLE), in order to inves-tigate the role of miR-326 on Treg cells and pathogenesis as well as its association with disease activity of SLE. Methods Twenty milimeter anti-coagulated peripheral blood was obtained from 52 SLE patients and 20 healthy controls. Treg were purified by MACS from peripheral blood, in which the quantity of miR-326 and Ets-1 mRNA were assessed by real-time polymerase chain reaction (PCR). Data were analyzed by using Mann-Whitney U test and Spearman correlation analysis. Results Compared with healthy controls [0.921(0.345, 1.879)], the expression of miR-326 mRNA level was significantly higher in Treg from SLE patients [2.927 (0.518, 8.662) (Z=-3.756, P<0.05). The difference between new-onset SLE patients [8.878(5.922, 12.466)] and recurrence group [3.512(0.582, 11.223)] with healthy controls was significant (Z=-2.135, Z=-4.928, P<0.05). The expression level of miR-326 in new-onset SLE patients was higher than inactive SLE patients (Z=-4.928, P<0.05). Significant difference of the expression level of miR-326 mRNA was found between new-onset SLE patients with serous cavity effusion [7.606(0.656, 16.795)] and new-onset SLE patients without it [1.840(0.576, 13.025)](Z=4.263, P<0.05). Our analysis showed that significant positive correlation was found between the expression of miR-326 mRNA in Treg with CRP (rs=0.481, P<0.05) and anti-C1q antibody (rs=0.729, P<0.05) from new-onset SLE patients. Conclusion The expression level of miR-326 is upregulated in Treg from SLE patients and is associated with disease active index, which suggests that miR-326 in Treg may participate the pathological process and disease activity in SLE.

Objective To compare the high risk factors, complications, treatment and prognosis of respiratory distress syndrome (NRDS) in neonates at different gestational age (GA). Methods Between August 2012 and July 2013, 156 neonates with RDS were selected and distributed into 3 groups, 42 early preterm (GA<34weeks), 52 late preterm (GA 35 to 36 weeks), and 62 in term group (GA≥37 weeks). Retrospectively analysis was performed for high risk factors, complications, treatment and prognosis of the three groups. Results In 156 neonates with RDS, the male and female proportion was 2.25:1. All groups had more males, but the gender difference has no statistical signiifcance in three groups (P=0.923). The onset time of RDS and the hospitalization time both show an increasing trend of statistical signiifcance (P<0.05). Comparing the difference of high risk factors for RDS of the 3 groups, birth asphyxia, placental abnormalities, multiple pregnancy, premature rupture of membranes was most common in early preterm group, and followed by late preterm group, and C-section was most common in term group and unexplained preterm was more common in early preterm group than that in late preterm group (all P<0.05). Among the three groups, the ratio of pulmonary surfactant application was the lowest in the term group, the ratio of X-ray grade over II was high-est in early preterm group, oxygen and hospitalization time were the longest in early preterm group (P<0.05). The risks of com-plicated with pulmonary infection, intracranial hemorrhages and bronchopulmonary dysplasia were the highest in early preterm group and the risk of complicated pneumothorax was the highest in term group. Among three groups, the recovery rate was the lowest in the early preterm group (P<0.01). Conclusion The clinical characteristics, high risk factors, complications and treat-ment responses of RDS in neonates with different GA were different, so GA should be considered for diagnose and treatment. For the term infants, the elective caesarean section should be strictly controlled, in order to reduce the incidence of RDS.

Objective In the early life period when eyes grow rapidly,visual experience can play an important role in axial growth and refractive development. For instance, depriving the eye of form vision during infancy will accelerate axial growth, resulting in substantial amounts of myopia, called form deprivation myopia (FDM). Similarly, imposing the eye with a negative lens produces compensating myopic growth in many species, called defocus induced myopia (DIM) . As one of the important visual experiences,color vision and its effects on eye growth deserve to be investigated. The purpose of this study was to investigate the effect of 530 nm monochromatic light and establish an innovative model of myopia in guinea pig by exposing to this monochromatic light. Methods Twenty male guinea pigs at 2 weeks old were randomly assigned to two groups (n = 10) . The experimental group was raised under the condition of 330 nm monochromatic light illumination. The control one was bred under white light illumination with 5000 k color temperature. These guinea pigs were raised in a specially designed cage. The light source was provided by specially made LEDs (green: peak value 530 nm and half bandwidth 30 nm; white: color temperature 5000 K) . The illumination parameters of the two groups were identical and the light quantum number was 3 x 10~(-4)μmol·cm~(-2)·s~(-1) . Through measuring,the irradiance value was 0.150 mW·cm~(-2) for green light and 0.247 mW·cm~(-2) for white light approximately. All animals were kept under a 12/12 h light/dark cycle (light: 8 a.m. - 8 p.m. ) ,in the temperature of 22℃ - 26℃ and a relative humidity of 55% -65% . Both groups underwent biometric measurement including refraction,corneal curvature and axial length,etc. before and after twelve weeks treatment. The refraction was examined using a streak rednoscope and trial lenses in a dark room one hour after topically administering a cycloplegic eye drop. The radius of comeal curvature was measured with a keratometer (Topcon OM-4, Japan) and axial components was measured by A-scan ultrasonagraphy ( Opticon Hiscan A/B).Repeated measurements were undertaken. Only the right eye's parameters of each guinea pig were used for analysis. Unpaired (-tests were used in all comparisons between the two groups of eyes with a statistical analysis software (Stata, version 7.0) . Results Before treatment, the refraction of experimental group was 4.6 ± 0.59 D.and that of the control group was 4.63 ± 0.48 D. The axial and vitreous body length was 7.48 ±0.11 mm and 3.16 ±0.07 mm in the experimental group,respectively,and 7.55 ±0.16 mm,3.21 ±0.09 mm in the control. The differences between the biometric parameters of the two groups including refraction, comeal curvature and axial components were not significant ( P > 0.05) . However,after a twelve-week exposure, the variation of refraction in the experimental group was -3.125 ± 0.76 D,and - 1.075 ± 0.71 D was observed in the control group. There was a 2.0 D myopia in the experimental group compared with the control. Axial length grew 0.98 ± 0.13 mm in the experimental group and 0.77 ± 0.22 mm in the control. Vitreous body extended to 0.33 ± 0.14 mm and 0.13 ± 0.14 mm in the two groups, respectively. The refraction of the experimental group shifted more towards myopia ( P < 0.0001) accompanied with a more accelerated speed of axial growth and vitreous body's extension ( P < 0.05) compared with that of the control group. There were no significant differences in the radius of comeal curvature, the depth of anterior chamber and the lens thickness between the eyes of the two groups at the end of the experiment ( P > 0.05) . Conclusion The 530 run monochromatic light can accelerate the prolongation of axial length and vitreous body inducing axial myopia in guinea pigs.
