Traumatic optic nerve injury ( TON) is caused by direct or indirect optic nerve trauma, which is one of a serious complication of craniocerebral trauma. lts prognosis poor and usually bring permanent vision damage. At present, optic nerve injury and regeneration is hot in neurobiology research. To build an ideal experimental animal model is extremely important in research and development in the treatment of optic nerve injury. ln this article, we review the methods of making rat models of traumatic optic neuropathy, clinical similarities, advantages and disadvantages of among these models, to provide reference for more experimental study.

Objective To investigate the effect of tramadol combined with sufentanil on postop-erative analgesia in patients received upper-abdominal surgery.Methods One hundred and fifty pa-tients scheduled for selective upper-abdominal operation were randomly divided into five groups (n=30 each):Tramadol group (T);large dose sufentanil combined small dose tramadol group (TS1 );balanced tramadol and sufentani group (TS2 );small dose sufentanil combied large dose tramadol group (TS3);sufentanil group (S).Postoprative VAS scores were recorded respectively at 1,4,8, 12,24,36,48 h when be in quiet and turning 90 degree,Ramsay sedation score,analgesia pump pressing times and side effects were also recorded.Results VAS scores in group TS2,group TS3 and group S at each time point both be in quiet and turning 90 degree were significantly lower than that of group T and group TS1 (P <0.05).Group S sedation score significantly higher than group T (P <0.05).No significant difference in other groups.Conclusion Balanced tramadol and sufentanil group has best analgesic effect and least side effects.With the increasing doses of sufentanil,its analgesic effect was not obvious enhancement.

Objective To compare two different gastric tube insertion methods on neonatal pain responae.Methods From April to July 2010,47 neonatal patients underwent gastric tube insertion in the neonatal department of our hospital were randomly classified into two groups:the nasal gastric tube insertion group(28 cases) and the oral gastric tube insertion group( 19 cases).Neonatal pain score and incidence of complications during gastric tube insertion between both groups were compared.Results The mean rank of pain scores were significantly higher in the nasal gastric tube insertion group than in the oral gastric tube insertion group.The incidence of pain and complications were higher in the nasal gastric tube insertion group than in the oral gastric tube insertion group.Conclusions The impact of oral gastric tube insertion on neonatal pain response is not significant,and few complications occur during oral gastric tube insertion,so it is worthy of clinical application.

Objective To study the antitumor effect of toremifene on MCF7 cell lines,and investigate the role of mitogen-activated protein kinase pathway. Methods Inhibitory effect of toremifene alone or combined with MEK inhibitor PD98059 on MCF7 cells was measured by SRB test,and that on phosphorylated ERK was detected by Western blotting.Results Toremifene exhibited a concentration-dependent inhibitory effect on the activity of MCF7 cells.Phosphorylated ERK was significantly inhibited by 5,10 and 20 mmol/L toremifene.Combined with PD98059,toremifene had a significantly enhanced cytotoxity effect,which exceeded that of application alone. Conclusion Mitogen-activated protein kinase pathway may play an important role in the antitumor effect of toremifene which is independent of estrogens.Combined with PD98059,the antitumor effect of toremifene can be reinforced,indicating a synergistic effect of these two drugs.

Objective To investigate the clinical teaching situation by using developmental inspection of School of Medicine,Shanghai Jiaotong University(SJTU-SM),and to put forward some suggestions. Methods By checking questionnaires and informal discussions,the relevant information was collected and analyzed by using SPSS statistics sofware. Results The clinical teaching quality of SJTU-SM was basically satisfied.The satisfaction from internship of grade 2004 was better than that of grade 2003.However,some problems in clinical teaching must be improved.Conclusion The investigation showed that the clinical teaching quality of SJTU-SM is being improving.However,in order to achieve the international accreditation standards,the quality guarantee system of clinical teaching need to be further perfected.

BACKGROUND: Hemiarthroplasty is widely recommended for the treatment of femoral neck fractures in elderly patients, but it is controversial in choosing cemented or cementless fixation types. OBJECTIVE: To compare the clinical effects of cemented hemiarthroplasty with cementless hemiarthroplasty for the treatment of femoral neck fractures in elderly and to provide a scientific basis for the selection of clinical prosthesis. METHODS: 167 elderly patients with femoral neck fractures undergoing hemiarthroplasty in the Foshan Hospital of Traditional Chinese Medicine from March 2013 to March 2015 were enrolled in this study. According to the type of prosthesis, patients were divided into cementless group (n=81) and cemented group (n=86). The operation time, intraoperative blood loss, hemoglobin levels 1 day after surgery, reoperation rate, mortality and complications at 1 year after surgery were compared. After surgery, clinical function of hip joint was assessed by Harris scoring system. The pain was evaluated by Visual Analogue Scale. RESULTS AND CONCLUSION: (1) All patients were followed up for ≥ 12 months. (2) The operation time in the cementless group was significantly shorter than that in the cemented group (P < 0.01). (3) There was no significant difference in the intraoperative blood loss and hemoglobin levels at postoperative 1 day (P > 0.05). (4) There were no significant differences in Harris hip scores and Visual Analogue Scale score at various time points between both groups (P > 0.05). (5) The incidence of thigh pain in cementless group was slightly higher than that in cemented group at 1 week, 1 and 6 months after operation, but the differences were not statistically significant (P > 0.05). Two patients died from myocardial infarct in the cementless group, and one patient died from pulmonary infection in the cemented group. The mortality was not significantly different at postoperative 1 year between the two groups (P > 0.05). No complications, such as prosthesis loosening and sinking, periprosthetic fracture, and periprosthetic infection, which needed to be refurbished, occurred in both groups. (6) Our findings suggest that both cemented and cementless hemiarthroplasties can obtain satisfactory effect in the treatment of femoral neck fractures in the elderly patients. Cementless hemiarthroplasty can significantly shorten operation time.
