Objective To explore the role of Neuroretinal Rim Volume/ Rim Area(RV/RA) ratio in Early Diagnosis of Primary Open Angle Glaucoma(POAG).Methods All candidates were divided in to three groups(31～40 years old,41～50 years old,51～60 years old),Heileberg Retina Tomography(HRT)were used to test retinal disk,and the RV/RA ratio were calculated.Result There are obviously difference between nomal and POAG group in RV/RA(P

ObjectiveTo study the distribution and expression of NMDA receptor subunit 2A in the spinal cord of morphine tolerant rats. MethodsTwelve Sprague-Dawley rats were randomly divided into two groups with 6 rats each: control group (C) were intrathecally administrated 0.9% NaCl 10μl and morphine group(M) received 10μg morphine (i.t.). Drugs were administrated twice daily for 7 consecutive days. Tail flick latency (TFL) in the hot water immersion test was used to evaluate changes of thermal hyperalgesia latency of each group before and 30min after administration every morning. Rats were killed the day after last administration and L4～5 segment of the spinal cord was removed for determination the expression of NR2A by immunofluorescence method. ResultsTFL of group M was decreased gradually after chronic administration of morphine intrathecally. There was no significant difference between group M[(3.25±0.93)s] and group C[(2.66±0.27)s] on the 7th day (P＞0.05). A morphine tolerant model was established successfully. NR2A was distributed throughout the rat spinal cord. The expression of NR2A in group M(OD:9617±1233) was increased compared with group C(OD:2.66±0.93) (t=3.133,P＜0.05).ConclusionThe expression of NR2A was upregulated after repeated administration of morphine intrathecally in the superficial dorsal horn of spinal cord of morphine tolerant rats,which may be part of the mechanisms of morphine tolerance.

Tendons are dense connective tissues that mediate the attachment of the muscle system to the skeletal system. While the methods for clinical tendon repair remain less satisfactory, tissue engineering may pro- vide promising future. Therefore, understanding the natural tendon development process is important for tendon en- gineering. Scleraxis and Tenomodulin are relatively specific molecule makers for tendon and ligment and play im- portant roles in the tendon development. This article gives review of the molecular structure, the expression regula- tion, and the roles of Scleraxis and Tenomodulin in tendon development, in order to better understand the process of tendon development.

0.05) in tail flick test.MPE% in group MK was always higher than group M and descended more slowly than group M,especially from the d4 to d8(P0.05). Conclusion Ketamine could block the development of morphine tolerance partly due to its inhibition effect on pCREB protein.

Objective:To assess the efficacy and safety of oncoplastic breast-conserving surgery (OBCS) in the treatment of early breast cancer. Methods:The clinicopathological data of breast cancer patients who were treated with OBCS (67 cases) and standard breast-conserving surgery (SBCS;117 cases) in Affiliated Cancer Hospital of Guangxi Medical University were retrospectively analyzed. Postop-erative complication, specimen weight, margins, and surgery re-excision rate between the two groups were compared. Results:Sero-ma (14.9%versus 48.7%, P<0.001), hematoma (4.5%versus 14.5%, P=0.035), and poor wound healing (3.0%versus 11.9%, P=0.036) were more common in the SBCS group than in the OBCS group. The patient satisfaction in the OBCS group was statistically higher than in the SBCS group (P<0.05). Compared with standard surgery, oncoplastic techniques can be employed for significantly larger tumors (25.04 mm versus 21.14 mm, P<0.001). OBCS resulted in higher mean specimen weights (92.24 g versus 57.44 g, P<0.001), wider clear nearest margins (12.04 mm versus 9.58 mm, P<0.001), and wider furthest margins (24.16 mm versus 15.24 mm, P<0.001). No statisti-cal increase was observed in further surgery re-excision of margins. Conclusion:OBCS is more successful than standard wide local exci-sion in treating larger tumors and obtaining wider radial margins. Oncoplastic approach showed no increase in postoperative complica-tion rate. The postoperative complication was excellent. OBCS is a safe and effective procedure for early breast cancer.

Objective To investigate the effect of ulnar nerve with or without transposition during open reduction and internal fixation of distal humerus fractures.Methods A retrospective case control study was made on 74 cases receiving open reduction and internal fixation of distal humerus fractures between January 2008 and December 2015.There were 28 males and 46 females,with a mean age of 63.2 years (range,32-83 years).AO fracture classification was A2 type in seven cases,A3 type in four,C1 type in 14,C2 type in 28 and C3 type in 21.According to the intraoperative management of the ulnar nerve,the patients were divided into transposition group (n =43) and non-transposition group (n =31).Two groups were compared with respect to operation time,Mayo elbow performance score (MEPS),incidence of ulnar neuritis and postoperative complications.Results Follow-up lasted for 6-24 months (mean,11.7 months).Operation time differed significantly between transposition group [(110.9 ± 20.8) minutes] and non-transposition group [(95.6 ± 18.9) minutes] (P ＜ 0.05).MEPS in transposition group was excellent in 15 cases,good in 20,fair in six and poor in two.MEPS in non-transposition group was excellent in 10 cases,good in 15,fair in five and poor in one,with the same excellence rate of 81％ in comparison with transposition group (P ＞ 0.05).Incidence of ulnar neuritis showed no significant difference between transposition group (9％,4/43) and non-transposition group (7％,2/31) (P ＞0.05).Postoperatively,one case of superficial wound infection and two delayed healing were noted in transposition group;one case of superficial wound infection and one delayed healing were noted in non-transposition group.There was no significant difference in incidence of postoperative complications between groups (P ＞0.05).Conclusions Ulnar nerve with or without transposition can both achieve satisfactory clinical effect during open reduction and internal fixation of distal humerus fractures.But non-transposition group is associated with shorter operation time without increasing the incidence of ulnar neuritis.

Objective To investigate the effects of kui-yang-fang on trefoil factor 1 ( TFF1 ) , epidermal growth fac-tor ( EGF) and epidermal growth factor receptor( EGFR) in acetic acid induced gastric ulcers of rats. Methods50 rats were randomly divided into five groups. The rats of the gastric ulcer model were used by the icy acetic acid. After drug treatment for 14 days,the rats gastric mucosa was collected to compare to the ulcer index,then check the content of TFF1,EGF and EGFR with RT-PCR,and observe TFF1,EGFR with immunohistochemical staining. Re-sults Compared to the control,the levels of TFF1 and EGF in model group decreased, and the difference was not statistically significant. The EGFR level of model group was higher than that of normal group with no statistically significant difference. But the increase of kui-yang-fang groups and ranitidine group was more obvious,the difference was statistically significant (P<0.01). Compared to the model group,kui-yang-fang and ranitidine groups signifi-cantly elevated the level of TFF1,EGF and EFR in gastric ulcer,the difference was statistically significant ( P<0.01 ) . Immunohistochemical staining showed that TFF1 and EGFR expression in kui-yang-fang and ranitidine groups were significantly increased,the difference was statistically significant (P<0.01), but the increase of kui-yang-fang of high-dose group was more obvious. Conclusion One of the possible mechanism is kui-yang-fang pro-motes expression of TFF1,EGF and EGFR to protect and repair gastric tissue.

[Objective]To study the therapeutic effect of recombinant erythropoietin for contusion injury of spinal cord.[Method]Contusion injury of spinal cord was caused by weight dropping in 24 New Zealand rabbits.Twelve hours after injury,the rabbits in control group were given natural saline intravenously and rabbits in low,mediate and large-dose group were given rh-EPO 100 IU/kg,500 IU/kg and 1000 IU/kg respectively.Neurological status of lower limbs were scored at 24 hours,48 hours and one week after spinal cord injury.All rabbits were killed one week after injury and spinal cords were stained by HE and caspase-3 method.Electronic microscopy was used to evaluate ultrastructural injury.[Result]The neurological scores of EPO treated groups were significantly higher than that of control group.HE and Caspase-3 immunohistochemistry showed that histological and ultrastructural damage of EPO treated groups were less severe than that of control group.The caspase-3 positive neurons were significantly fewer than that of saline treated group.There was no significant difference of therapeutic effect between mediate and large-dose EPO treated groups.[Conclusion]Rh-EPO administered 12 hours after contusion injury of spinal cord could lessen histological and ultrastructural damage,prevent apoptosis of neurons and promote neurological recovery of spinal cord.Mediate dose of rh-EPO is the appropriate treatment choice for spinal cord injury.
