Objective To investigate the clinical efficacy and safety of medroxyprogesterone acetate in the treatment of endometrial atypical hyperplasia patients.Methods 98 cases of endometrial atypical hyperplasia patients were randomly divided into study group and control group with 49 cases in each group, study group were treated with medroxyprogesterone acetate treatment, and control group were given estradiol valerate tablets treatment.Two groups of patients were treated for 3 ~6 menstrual cycles, and clinical curative effect of two groups was compared.Results After treatment, the PBAC score and endometrial thickness inspection results in study group and control group respectively decreased significantly compared with before treatment (P<0.05), and the above indexes in study group were significantly lower than control group (P<0.05).After treatment, the hemoglobin value in two groups at 1st, 2nd, 3rd month after treatment was significantly higher than before treatment (P<0.05), and hemoglobin values at 1st, 2nd month after treatment was significantly higher than control group (P<0.05).The effective rate of study group (95.92%) was significantly higher than that of control group (81.63%, P<0.05).The recurrence rate during six months was 4.08% in study group, 8.16% in control group, and the difference was not statistically significant.Conclusion The efficacy of medroxyprogesterone acetate is better than estradiol valerate tablets in the treatment of endometrial atypical hyperplasia patients, which is safe and effective.

AIM:To observe the clinical characteristics of palm video keratitis and analyze the pathogeny. And to explore methods to cure and prevent it.
METHODS: A total of 591 patients were randomly selected. Firstly, the frequency of staring at palm video equipment were investigated and break-up time of tear film with slit-lamp were observed. Then the data were calculated and the clinical characteristics were described. Finally, the correlation between incidence rate and the two factors were analyzed by SPSS13. 0 respectively.
RESULTS:The incidence rate of palm video keratitis increased along with the frequency of staring at palm video equipment and decreased along with break- up time. There was significant relationship between incidence rate and the two factors respectively.
CONCLUSION:It is the most important pathogeny that staring at palm video equipment ahead and down for a long time which cause the change of tear film. That can reduce the frequency of using palm equipment and drop artificial tears to prevent and cure the disease.

Objective To establish animal model of guinea pig anaphylactic shock ,explore the expression of IL‐4 and IL‐10 in guinea pig serum ,provide scientific and objective evidence for medicolegal and clinical diagnosis of anaphylactic shock as well .Meth‐ods After 40 guinea pigs were classified into the experimental and the control groups ,in which the experimental group was 30 and the control group was 10 ,Elisa method was used to detect IL‐4 and IL‐10 by extracting serum of guinea pigs in the experiment group and the control group .Results The IL‐4 levels of serum in experimental group was higher than that in control group (P<0 .01);the IL‐10 levels of serum in experimental group was higher than that in control group (P<0 .01) .Conclusion The level of serum IL‐4 and IL‐10 in the experiment group are obviously higher than that of the control group .This provides an evidence for an‐aphylactic shock forensic identification and clinical diagnosis .

Proteomics, a new branch of science, has been used to study protein expressions on the molecular level with a dynamic perspective. Organisms under varying states may express different proteins, which results in the set-up of differential proteomics. Research methods of differential proteomics include the separation and identification of proteins. Differential proteomics has a rapid development in recent years. In the study of acupuncture, researchers have reached certain achievements using differential proteomics to investigate the mechanisms of acupuncture treatment for some diseases, including acute spinal cord injury, ischemic cerebrovascular disease, Parkinson's disease and neuralgia.

The netrin family represented by netrin-1 is currently one of the most concerned axon guidance factors. Netrin-1 plays guidance roles for axon growth and cell migration by the dual mechanisms of attracting/excluding during the embryonic development. At the same time, netrin-1 also widely expresses in the adult nervous system and involves in the reconstruction of the structure and function after the achft nervous system injury. This article reviews the roles of netrin-1 in ischemic brain injury.

Fabry disease is an inherited metabolic disease, resulting from a deficiency of the enzyme a-galactosidase A activity. Principal clinical manifestation of Fabry disease was limb pain episodes, angioceratoma, and progressive damage of heart,brain, kidney. Although Fabry disease cannot be cured at present,early diagnosis and enzyme replacement therapy can change the prognosis completely.

Objective To explore the neuroprotective effect of dexmedetomidine ( Dex) in rats ex-posed to focal cerebral ischemia/reperfusion ( I/R) induced by middle cerebral artery occlusion ( MCAO) and the possible mechansims.Methods Adult male Sprague-Dawley rats were subjected to MCAO for 90 min followed by reperfusion for 24 h and Dex ( 15μg? kg-1 ) was infused through the left femoral vein im-mediately after the onset of MCAO.The PI3K inhibitor LY294002 ( LY,10 mM,10 μl) or eNOS inhibitor L-NIO ( 1 mg? kg-1 ,10μl) was intracerebroventricular administered before ischemia using a microinjecton. The neurological deficit score,brain edema,cerebral infarct volume,and neuron survivals were evaluated after 24 h of reperfusion.The expression of p-Akt ( Ser473) and p-eNOS ( Ser1177) in the ischemic hemicere-brum was detected by Western Blot.Results Compared with I/R group,the neurological deficit score,cere-bral infarct volume,and the degree of brain edema were significantly reduced in the rats treated with Dex ((2.3±0.4) vs (3.9±0.6),(19.3±3.5)%vs (40.5±5.4)%,(61.8±8.1)%vs (76.3±8.5)%,all P<0.05)re-spectively,and the number of survival neuron in the hippocampal CA1 and cortex was significantly increased ((136.5±15.8)/mm vs (53.5±7.9)/mm,(253.8±26.4)/mm3vs (112.5±14.6)/mm3,all P<0.01) respec-tively.The neuroprotection in DEX group was significantly inhibited by LY and L-NIO ( P<0.05) .In addi-tion,the expression of p-Akt and p-eNOS in the ischemic hemicerebrum was markly reduced in LY group compared with that in DEX group ((3.94±0.45) vs (0.85±0.21),(2.14±0.25) vs (0.79±0.29),all P<0.01) ,while there was no significant difference in the expression of p-Akt in the ischemic hemicerebrum be-tween L-NIO group and DEX group ((3.76±0.33) vs (3.94±0.45), P>0.05).Conclusion Dex can reduce cerebral injury in rats exposed to focal I/R,which is mediated by the activation of PI3K/Akt-eNOS pathway.
