Research progress on the effect of low concentration atropine on the prevention and control of myopia in children and adolescents among children and adolescents / 中国学校卫生

Abstract@#Myopia is a common refractive error in the process of development. With the high incidence and low age of myopia in children and adolescents, it has become a worldwide public health problem, seriously endangering physical and mental health. The prevention and control of myopia has a long way to go. Low concentration atropine, as an M type choline receptor inhibitor, has been proved by medical research to effectively delay the progress of myopia. This paper reviews the relevant studies at home and abroad in recent years. The optimal concentration of low concentration atropine, the best clinical regimen and possible potential side effects were discussed. From the point of view of school public health, this paper discusses the significance of low concentration atropine for the prevention and control of myopia among school age students, in order to provide a reliable basis and new ideas for the follow up clinical application of atropine and myopia prevention and control strategies for school students.

Protective Effects of Extract of Periplaneta Americana on Liver Fibrosis in Rats / 天津医药

Objective To investigate the protective effects of extract of Periplaneta americana (APA) against carbon tetrachloride (CCl4)-induced hepatic fibrosis in rats. Methods Seventy SD rats were divided into five groups:normal con-trol group (C), model control group (M), extract of APA 1 group (APA1), extract of APA 2 group (APA2) and reduced glutathi-one group (R). The liver fibrosis model was induced by injecting 40%CCl4-olive solution subcutaneously for seven weeks in M, APA1, APA 2 and R groups. Drugs were given at the same time. Rats were killed at 7-week (C, M, APA1 and R groups), and were killed at 9-week (APA2 group). The serum values of transaminase (ALT, AST), albumin (ALB), hyaluronic acid (HA) and laminin (LN), and hepatic inflammation and fibrosis were detected respectively. The expressions of apoptotic relat-ed gene Bcl-2 and Bax protein in central veins and portal areas of hepatic lobules were detected by immunohistochemical method. Results Rats showed poor nutritional status, and significantly increased transaminase, HA and LN in M group, but the serum level of ALB was significantly lower than that in C group. There was extensive necrosis of liver cells, obviously fi-brosis or cirrhosis in model rats’liver tissues. The serum contents of ALT, AST, HA and LN were significantly decreased, the serum level of ALB were significantly increased in APA1,APA2 and R groups (P<0.05). There were complete hepatic lobule and no obvious fibrous tissue hyperplasia in liver biopsy of APA1 and R groups. The values of Bcl-2/Bax proteins in central vein of liver tissues were significantly higher in APA1,APA2 and R groups than those of M group (P<0.05), but the ratio of Bcl-2/Bax was lower in periportal area of liver tissues (P<0.05). There were significantly higher body weight and ALB levels in APA1 group than those in R group (P<0.05). The level of transaminase was slightly higher in APA1 group than that of R group. The degeneration of liver cells was found mostly in R group. Conclusion The extract of Periplaneta americana has a role in protecting liver cells, inhibiting the progression of hepatic fibrosis, and improving the nutritional sta-tus of trial rats.

Effect of follicle stimulating hormone on cryopreserved sheep ovarian tissue xenotransplantation / 中国组织工程研究

BACKGROUND: Transplantation of fragments of ovarian cortex is performed without vascular reanastomosis, therefore, to increase the tolerance of ovarian tissue to the freezing-thawing and ischemic injuries is critical for follicular survival and functional longevity of the graft.OBJECTIVE: To investigate the effect of follicle stimulating hormone (FSH) on the morphological and function of sheep ovary tissue in the process of cryopreservation, so that to provide new freezing method for human ovary tissues. METHODS: Healthy BALB/c strain female nude mice were equally and randomly divided into 3 groups and subjected to heterotopic transplantation of fragments of sheep ovarian cortex. (1) Control group: transplantation following sampling; (2) experimental group: transplantation following freezing-thawing, and the solution was free of FSH; (3) FSH group: the freezing and thawing and culture fluid contained FSH. The estrous cycle recovering rate, estrous cycle recovering time, the number of follicle were observed following transplantation. The histological changes, and the level of E2 in blood serum were observed at 4 weeks after transplantation.RESULTS AND CONCLUSION: There were no significant differences in estrous cycle recovering rate and number of follicle/PHF between FSH and control groups (P> 0.05), but the number of follicle was greater than the experimental group (P< 0.05). Moreover, the time of estrous cycle recovering in FSH group was similar to control group, but shorter than experimental group (P < 0.05). There were more developing follicular in FSH group, but few in experimental group at 4 weeks. No significant difference was detected in E2 level in blood serum between FSH and control group (P > 0.05), but significantly greater than the experimental group (P< 0.05). Results show that FSH addition in vitrification fluid can improve ovarian follicle survival following cryopreserved sheep ovary tissue transplantation.

Relationship Between the Central Hypotensive Effect of Acupuncture or Melatonin and the Changes of Medullary Amino Acid Neurotransmitter / 针灸推拿医学（英文版）

To investigate whether changes of amino acid neurotransmitter releases in the rostral ventrolateral medulla (rVLM) were related to acupuncture and to the antihypertensive effect of melatonin (Mel) microinjected into the anterior hypothalamic area (AHA) of rats with stress-induced hypertension (SIH), as well as to compare and analyze the relationship between the both antihypertensive mechanisms of acupuncture and of Mel in the AHA. Methods: Animal model of SIHR was made by electric foot shocks combined with noises. Electroacupuncture (EA) was used and Zusanli acupoint of both side was selected. The technique of drug microinjection into the brain was used to observe the change of blood pressure (BP), and synchronously, brain microdialysis was performed for collecting dialysate samples, and then the concentration of amino acid neurotransmitters in the dialysate samples was determined by high performance liquid chromatography combined with fluorescent detection (HPLC-FD). Results: After the animal received stress treatment, the BP elevated, synchronously, the release of glutamate (Glu) in the rVLM increased, and when EA was performed, the elevated BP of the rats with SIH decreased,simultaneously, the release of Glu in the rVLM decreased also. After Mel was microinjected of into the AHA of the SIHR, the elevated BP attenuated, meanwhile, the release of Glu decreased,and those of γ-aminobutyric acid (GABA) and taurine (Tau) increased in the rVLM.Administration ofbicuculline, an antagonist of GABAA receptor, into the rVLM prior to microinjection of Mel into the AHA could partially block the depressor effect of Mel in the AHA. Conclusion: The decrease in the release of Glu in the rVLM contributes to the antihypertensive effect of both acupuncture and Mel in the AHA in the rats with SIH, and the increase in the release of GABA and Tau in the rVLM is also important to Mel in the AHA.
