BackgroundWith the number of diabetics increases,people pay more attention to the diabetic keratopathy.The major mechanism leading to diabetic keratopathy is diabetic corneal neuropathy.So it is significant to observe pathologic mechanism of diabetic corneal neuropathy. Objective To investigate the protective effects of edaravone( a free radical scavenger) on corneal nerve of rats with experimental diabetic corneal neuropathy,then explain the effects of oxidative stress in the pathologic mechanism of diabetic corneal neuropathy. Methods Seventy Sprague-Daxley male rats were taken as experimental subjects and 20 of them were used as normal control group.The remaining 50 were induced to be diabetic mellitus by a single intraperitoneal injection of streptozotocin and divided into 2 groups randomly:edaravone treated group and diabetic control group.In the edaravone treated group,edaravone(0.2 g/L) eye drops were used 3 times a day until the animal was killed.Five rats in each group were sacrificed at 6,8,10 and 12 weeks respectively.Then the corneal sensation,number of corneal nerve fibers,morphology,content of malondialdehyde(MDA) and activity of superoxide dismutase(SOD) in the corneal tissue were detected.ResultsIn the diabetic control group,the corneal sensation and the number of corneal nerve fibers were decreased,the density of neural network for cluster was sparse,the nerve activity was decreased,the content of MDA in the corneal tissue was significantly increased,the activity of SOD in the corneal tissue was significantly decreased (P＜0.01 ).Accompany with the course of disease,the above change was obvious day after day.Compared with the diabetic control group,the corneal sensation and the morphological abnormalities in corneal nerve of edaravone group were improved significantly which had the partial branches to the 12th week,the content of MDA in the corneal tissue was significantly decreased,the activity of SOD in the corneal tissue was significantly increased (P＜0.01).Conclusions Edaravone can lower diabetic corneal nerve of rats with experimental diabetic corneal neuropathyinjury,Oxidative stress may be a critical pathologic mechanism of diabetic corneal neuropathy.

OBJECTIVE: To explore the anti-tumor activities of a new compound 3β,12β,20(S)-trihydroxy dammarane-3-O-β-D-glucopyranosyl (1-2)-β-D-glucopyranoside (HRG), which is a substance of ginsenoside structure modification, in vivo. METHODS: Liver cancer H22 tumor model on the chick chorioallantoic membrane (CAM) was established to observe the effects of HRG on tumor growth, the number of induced vessels and the growth inhibition rate. The implanted tumors were dyed by hematoxylin-eosin (HE), and the morphological properties were studied with light microscope. Immunohistochemistry (SP method) was used to detect the expressions of the implanted tumor's MVD and VEGF. RESULTS: HRG inhibited the tumor growth at 25, 50 and 100 μg · mL-1. Compared with the model control group, the inhibitory rates of the tumor growth were 27.73%, 50.02%, and 64.21%, respectively. HRG significantly reduced the number of tumor-induced vessels. At the same time, there existed different degree necrosis among the treatment groups, and the degree of necrosis had an inverse relationship with the number of tumor-induced vessels. In addition, HRG reduced the MVD of the implanted tumors, and decreased the expression of VEGF. CONCLUSION: HRG has good anti-tumor activities in vivo, and can significantly inhibit the growth of liver cancer H22-CAM tumor and the induction of angiogenesis. The mechanisms may be associated with lower tumor MVD and VEGF expression.

Objective To study the relationships between androgen receptor (AR)expression and the clinicopathological features and prognosis of young patients (age≤35 years)with early-onset breast cancer in Xinjiang.Methods One hundred and forty-five young patients (age≤35 years)with invasive breast cancer who underwent surgery in Affiliated Cancer Hospital of of Xinjiang Medical University from January 201 0 to December 201 2 were collected.The expressions of AR in 1 45 patiens with early-onset breast cancer were detec-ted by immunohistochemical method.The relationships between AR expression and the clinicopathological fea-tures and prognosis of patients with early-onset breast cancer were retrospective analysed.Results The posi-tive rate of AR expression of patients with early-onset breast cancer in Xinjiang was 69.0% (1 00 /1 45).Single factor analysis showed that AR expression was related with neurovascular invasion (χ2 =5.309,P =0.021 ) and lymph node metastasis (χ2 =6.073,P =0.01 4),but it was not related with ethnicity (χ2 =0.097,P =0.755),age (χ2 =0.045,P =0.831 ),feeding history (χ2 =0.066,P =0.797),family history of cancer (P =0.556),histological grade (P =0.469),tumor size (χ2 =1 .006,P =0.605)and clinical stage (χ2 =4.381 ,P =0.223).The median follow-up time was 47 months.There was no significant difference between AR expression and disease-free survival of patients with early-onset breast cancer (χ2 =1 .972,P =0.1 60). Conclusion Early-onset breast cancer patients with AR positive are more likely to appear lymph node metasta-sis and neurovascular invasion than the patients with AR negative,which has certain guidance means for the treatment of early-onset breast cancer with lymph node metastasis positive.

OBJECTIVE:To optimize the extraction technology of total volatile oil from Cinnamomum cassia Presl. and Cyper-us rotundus L. in Hegan lipi granules. METHODS:With the extraction rate of total volatile oil as the index,Box-Behnken response surface method was applied to investigate the effects of water amount,soaking time for medicinal materials and extraction time by distillation on the amount of the extracted volatile oil and optimize the extraction technology of total volatile oil from C. cassia Pre-sl. and C. rotundus L. in Hegan lipi granules,and verification tests were conducted.

Doctors ought to belong to a social stratum with fairly high incomes. The high input and long cycle that is essential to becoming a high-caliber doctor constitute the high costs of the medical profession; high technology, high responsibility and high sacrifices constitute the high risks of the medical profession; the contrast between the input of high intelligence, high academic degree, and high expertise and the output of low economic income tends to warp the minds of doctors. The inversion of the burden of proof in medical lawsuits has practically put doctors on the weak side. Their rights and interests as well as their practice circumstances have been disregarded. For the sake of the development of the health cause, it is imperative to respect the labor of doctors and to provide them with sound survival circumstances.
