Abstract?AIM: To characterize the effects of sodium iodate on mouse retinal morphology and function.?METHODS: Sodium iodate at 35mg/kg ( body weight) was administered by tail vein injection into adult 6-8wk C57BL/6J mice. Morphological and functional changes of the retina were assessed at 6h, 1, 3, 5 and 8d after injections by fundus imaging, optical coherence tomography (OCT), ERG and histology. Mice in control group were give tail vein injection of equivalent dose of normal saline. All the eyeballs were removed for paraffin section and H-E staining.?RESULTS: The fundus photographs images at 6h after injection showed obvious changes, which were light red in retina and showed retinal blood vessels radial arranged. At 6h after injection, off-white drusen-like change was found at fundus. While there were no observable changes in OCT image and ERG. At 1d after injection, the fundus lesion aggravated and the drusen increased gradually. There were retinal pigment epithelial ( RPE) disorders, photoreceptors and outer nuclear layer (ONL) damage through OCT. At 3d after injection, the retina lesion aggravated further and the retina became edema. At 5d after injection, the retina edema cleared away, the optic nerve became white and the fundus lesions increased. At 8d after injection, the RPE layer, photoreceptors and ONL were destroyed obviously. In the process, ERG showed the amplitudes of a- and b-wave decreased in a time-dependent manner. H-E staining showed that cells in retina of mice in control group were neatly arranged and well- distributed. The outer layer retina of sodium iodate injection group was wave-like, the normal structure of RPE disappeared and black round sediment could be seen which increased with time. At 8d after injection, there were any normal RPE.?CONCLUSION: The tail vein injection of sodium iodate can well simulate the pathogenesis of age - related macular degeneration which can provide a good animal model for AMD.

Objective : To investigate the prevalence of dyslipidemia among overweight and obese primary and middle school students in Tongzhou District, so as to provide the evidence for the implementation of comprehensive health education and early interventions for overweight and obese students. Methods : The basic information, physical examinations and blood lipid testing results were collected from the primary and middle school students in Tongzhou District from 2015 to 2019 through the nutrition and health monitoring project among students in Tongzhou District. The epidemiological characteristics of overweight and obese students with dyslipidemia were descriptively analyzed. Results : Among the 1 483 primary and middle school students detected, the overall prevalence rates of overweight, obesity and dyslipidemia were 12.68% ( 188 students ), 20.43% ( 303 students ) and 20.57% ( 305 students ), respectively. The prevalence of dyslipidemia was higher in overweight and obese students ( 24.44% ) than in students with normal weight ( 18.65%, P<0.05 ), and the prevalence of dyslipidemia was higher in male overweight and obese students than in female overweight and obese students (29.00% vs. 18.92%, P<0.05), while higher prevalence of dyslipidemia was seen in middle school students than in primary school students ( 37.72% vs. 20.32%, P<0.05 ). In addition, the prevalence of dyslipidemia was higher in students with daily exercise of less than a hour than in students with daily exercise of a hour or longer ( 27.88% vs. 18.44%, P<0.05 ). Conclusions The prevalence of dyslipidemia is high among overweight and obese primary and middle school students in Tongzhou District. Health educations should be reinforced to male, middle school students with daily exercise of less than a hour.

The reimbursement on high-value drug expenses for patients is an important approach of catastrophic disease medical insurance.Hong Kong has established in a drug safety network, that has achieved remarkable results in improving the accessibility to high-value drugs and the burden of disease and effectively alleviated patients' financial burden.This paper systematically analyzes the history, process of adding drugs to directory, application conditions for drugs and patients, development status, and characteristics of drug safety network in Hong Kong.This study points out that although Mainland China has gradually established the high-value drug directory for catastrophic disease through the method of drug negotiation, the mechanism of high-value drug directory is not mature yet.To achieve the convergence between high-value drug directory, basic medical insurance drug directory, and new rural cooperative medical scheme drug directory, Mainland China needs to: 1) First, learn from the drug safety network in Hong Kong and establish access and exist mechanism for high-value drug directory;2) Then, expand insurance coverage of high-value drugs by establishing a multi-channel and socialized financing mechanism;3) Finally, strengthen the major disease medical insurance by adhering to the principles of buying drugs and getting drugs for free and reforming the fixed-ratio-reimbursement model.

In this article we report the results on the synthesis and accumulation of PHAs by Rhodocista pekingensis (strain 3-p), a phototroph that was isolated from wastewater treatment plant. Our results showed that the optimal conditions for PHAs accumulation with strain 3-p were as following: 0.01% Yeast Extract, 0.01% NH 4Cl, Acetate 5 g/L, and medium pH of 7.0～7.2.Under optimized conditions, strain 3-p accumulated PHAs up to 60% of its cellular dry weight. Enzymatic activities of ?-ketothiolase, acetoacetyl-CoA reductase, and PHA polymerase were detected and their activities increased as PHA synthesis initialized. Based on these study, we proposed the metabolic pathway of this strain should be:Acetate (or other fatty acids) - Acetyl-CoA --- thiolase Acetoacetyl-CoA --- reductase D (-)-?-Hydroxybutyryl-CoA ----- PHA polymerase PHAs.

12 isolates of thermoacidophilies were obtained from samples of hot springs of Southern China's Guangdong and Yunna provinces. All isolates are heterotrophic. Cells are rods, Gram positive or variable. The optimal pH and temperature for growth are 3.5-5.5 and 43℃-52℃, respectively. Based on their morphological physiological properties and their 16S rDNA sequences, they were identified as members of Alicyclobacillus.

?AlM: To observe the expression of Acin1 ( apoptotic chromatin condensation inducer 1 ) in congenital cataract mouse retina during development and investigate the differences of retinal apoptosis and the connection of lens and retina development between congenital cataract mouse and normal mouse.
?METHODS: There were congenital cataract mice ( 10 female and 5 male) and normal C57BL/6 mice (10 female and 5 male) . One male and two female mice were fed in the same cage randomly. The young mice were divided into two groups: congenital cataract group and normal control group. Five young mice were treated each group on 1, 5, 9, 14, 17, 21, 26, 60d. The left eyes were fixed with 4% neutral formalin to detect AClN1 protein by immunohistochemistry and retinas from right eyes were used to detect the mRNA expression of Acin1.
?RESULTS: Acin1 had sustained expression in each group. AClN1 protein gradually expressed from the ganglion cell layer, inner nuclear layer to the outer nuclear layer following retinal development. lt mainly expressed on ganglion cell layer and inner nuclear layer, but not neuroblastoma layer. AClN1 protein positive cells on P1 ~ P14d increased in normal control group, P17d reduced, after P21d positive cells of each layers decreased. The overall trend was similar in congenital cataract group with normal control group, P1 ~ P14d positive cells count was lower than normal control group, P17-P21d positive cells were flat and higher than the normal control group. Compared with the same day of the two groups, the differences except for P17, P26, P60d were significant (P<0. 05). The overall difference was statistically significant in congenital cataract group ( Fcataract=295. 07, P<0. 01);in addition to P1 and P5, P17 and P21, the differences were statistically significant ( P< 0. 05 ) compared with each other in congenital cataract group. The overall difference was statistically significant in control group (Fnormal=214. 21, P<0. 01); in addition to P1 and P5d, the difference was statistically significant ( P<0. 05) compared with each other in control group. The expression of P17d in congenital cataract group was lower compared with that of P14d in control group, the difference was statistically significant (P<0. 05). Acin1 mRNA trends of two groups were similar with AClN1 protein. Compared with the same day of the two groups, the difference was significant except for P17, P21, P60d (P<0. 05 ) . The overall difference was statistically significant in each other of the two groups ( Fcataract=522. 29, P<0. 01;Fnormal=472. 05, P<0. 01). The difference was statistically significant compared with each day in control group ( P<0. 05). Compared with all the rest of days except for P21 and P26d, the difference was statistically significant in congenital cataract group (P<0. 05).
?CONCLUSlON: Acin1 exist differential expression of time and space in mouse retina during development, congenital cataract crystal developmental disorder may affect the expression of Acin1 and retinal cell apoptosis and development.

Objective: To observe the therapeutic efficacy of tuina plus cupping on chronic fatigue syndrome (CFS). Methods: A total of 100 CFS patients meeting the inclusion criteria were randomly divided into a treatment group and a control group according to the random number table in the sequence of visit, with 50 patients in each group. The treatment group was treated with tuina plus cupping therapy, 3 times a week. The control group was given oral tablets of wild American ginseng lozenges. After 3 months of treatment, the score of fatigue questionnaire scale (FS-14) was observed and the efficacy was evaluated. Results: The total effective rate was 92.0％ in the treatment group, versus 76.0％ in the control group and the difference between the two groups was statistically significant (P<0.05). After treatment, the FS-14 scores of the two groups decreased, and the intra-group differences were statistically significant (both P<0.05). The change of FS-14 score after treatment in the treatment group was more significant than that in the control group (P<0.05). Conclusion: Tuina plus cupping is effective for CFS, and can improve fatigue symptoms significantly.
