Based on the undergraduates' education evaluation of 29 medical colleges and universities and the on-the-spot assessment of the students' mastery of the theoretical knowledge and their clinical practical ability, the teaching quality of each university was evaluated, the problems thus caused were analyzed and the suggestions were put forward.

Objective To analyze the clinical effect and safety of cortical bone decortication combined locking plate fixation for treatment of long bone nonunion of limbs. Methods Eighty patients with long bone nonunion of limbs who were treated in the Zhongshan Hospital Affiliated to Dalian University from Jun. 2010 to Jun. 2013 were selected as our subjects and their clinical data were recorded. According to different treatment methods,the patients were divided into control group and observation group,and each group with 40 cases. Patients in observation group were treated with cortical bone decortication combined locking plate fixation, while in control group were treated with locking plate combined slotted bone graft. Clinical effects and safety of two groups were compared. Results Excellent and good rate in observation group was 100%(40/40),obviously higher than that of control group(90. 0%(36/40);χ2 =4. 21,P﹤0. 05). Bleeding amount during operation in observation group was(370. 5 ± 56. 5)ml,obviously less than that of control group((486. 5 ± 64. 5)ml;t=8. 56,P﹤0. 01). And the fracture healing time was(5. 6 ± 1. 2)months in observation group,shorter than control group((7. 2 ± 1. 5)months;t =5. 27,P ﹤0. 01). The postoperative complication occurrence rate was 5. 0%(2/40),significantly lower than control group(20. 0%(8/40);χ2 =4. 11,P ﹤0. 05). Conclusion Cortical bone decortication combined locking plate fixation for treatment of long bone nonunion of limbs is safe and effective,and it can reduce operation injury and accelerate postoperative healing of fracture.

Esophageal cancer is a highly aggressive malignant tumor of the digestive tract. Despite the continuous development of sur-gical techniques and multidisciplinary treatments, the prognosis and overall survival of esophageal cancer patients is still poor. In re-cent years, the development of new molecular targeted therapy has become well advanced. Drugs that target tumor-related signal pathways and block the transmission of downstream signals can inhibit the growth and metastasis of tumor cells. Currently, esopha-geal cancer-targeted drugs are rarely approved officially. HER-2 inhibitor represents these types of drugs because of its positive expres-sion of metastatic adenocarcinoma. However, studies on the preparation of new drugs are not extensive. In this paper, the research progress of a new targeted therapy for metastatic esophageal cancer is reviewed.

Objective To summarize the key points of nursing the patients with simple 46 XY gonadal digenesis syndrome. Method Mental care and full preparation like nursing of the incisions , close observation of pains and nursing of adverse reactions from chemotherapy were critical for ensuring the patient′s discharge from hospital. Result All patients′height increased, secondary sex symdrome growed with armpit and pubic air growed. Conclusion Good mental nursing and targed professional nursing are critical for patients′health.

Objective To study the flurbiprofen axetil (FA) for postoperative analgesia of gynecological laparoscopic surgery and the changes of interleukin-6 in blood.Methods80 cases were selected for gynecologic laparoscopic surgery,the patients were randomly divided into 4 groups with 20 cases each group.Group A was given FA 50 mg and tramadol 1 mg/kg 30 minutes before the end of surgery.Group B was given FA 50 mg 5 minutes before induction of anesthesia and given tramadol 1 mg/kg 30 minutes before the end of surgery,and group C was given FA 50 mg five minutes before induction of anesthesia.Group D was given tramadol 2 mg/kg 30 minutes before the end of surgery.After the surgery,the VAS was observed in real-time of wake up (T1),and 2 hours (T2),6 hours (T6) and 24 hours (T24) after operating.The blood of each group was taken at the different time points including arriving in the room (T0),waking up (T1) and 6 hours (T6) after operating.The blood samples were hold for 30 minutes and centrifuged (3000 r/min,10 min),and IL-6 was detected using double-antibody sandwich ABC-ELISA.ResultsThe experiments showed that VAS in T1 time point of group A,B,C were lower than that of group D(1.40±0.26,1.67±0.37,1.60±0.42 vs 3.13±2.32).In T24 time point,VAS of group A,B were also lower than that of group D(2.13±1.24,2.00±1.25 vs 3.53±1.87),the differences were significant (P＜0.05).The experiments showed that concentration of IL-6 in group D was higher than that in group A,B,C at the T1 time point (12.26±6.56 vs 2.94±2.55,3.37±2.43 vs 2.93±1.16,P＜0.05).ConclusionsThe postoperative analgesic effect of Flurbiprofen axetil combined with tramadol on the ogynecological laparoscopic was superior to using any of the drug alone.Flurbiprofen axetil could inhibit increasing of IL-6 and have an effect against the inflammatory response induced by surgical trauma,and it has a good analgesic effect.

Objective To isolate and culture the rabbit mesenchymal stem cells,and explore the biological features in vitro.Methods Two milliliter of bone marrow was extracted from the tibia of juvenile rabbit under anesthesia and sterile conditions,and mesenchymal stem cells were obtained by density gradient centrifugation and inoculated to 100ml culture flask.The morphological changes,adherence rate and ultrastructure of the stem cells were observed.The surface markers and growth cycle of the mesenchymal stem cells were detected by flow cytometry,and biological features were observed by inducing the cells differentiate into osteoblasts.Results The adherence of mesenchymal stem cells started 2 hours after culturing,basically finished 20 hours later,and more than 90% of the cells were fused at the 15th day.Observed with transmission electron microscopy,the cultured cells showed typical ultrastructure of stem cells: numbers of microvillus mainly distributed on one side of the cells,irregular nuclei with indentation,and lots of cell organs.Analysis for the cell surface markers indicated positive expression of CD44 and CD90 and negative expression of CD45 in mesenchymal stem cells.Cell growth cycle assay showed that most mesenchymal stem cells(about 97%) stayed in stage G1 and G2.Three weeks after osteoblastic induction,the mesenchymal stem cells gradually produced small calcium salt crystals,the cells were positive in alkaline phosphatase staining,and Von Kossa staining showed many calcium salts in the cell clone as black reaction deposits.Conclusions The rabbit bone marrow mesenchymal stem cells isolated by density gradient centrifugation are of high purity and stable growth rate,and the cells' characters can be still maintained after serial subcultivation.Since easy to operate on isolation and proliferation,the mesenchymal stem cells could be used as the tissue engineering seed cells in repairing of intervertebral disc degeneration.

Objective To observe the mechanism of herbal cake separated moxibustion to hyperlipemia (HLP) and atherosclerosis (AS) rabbits on cell and molecular level. Method 75 rabbits were divided into 5 groups randomly:blank group, model group of HLP and AS, direct moxibustion group, herbal cake separated moxibustion group, herb group, 15 rabbits each group. Model rabbits of HLP and AS were built by immunity injury method. The expression of VCAM-1 mRNA and E-sel mRNA were determined with the method of RT-PCR.
