OBJECTIVETo establish the migraine rheumatism stasis syndrome animal model.

METHODThe rat migraine rheumatism stasis syndrome animal model was established through rheumatism stimulation with manual climate box, 5-HT reduction caused by reserpine and local cerebral vasospasm. General vital signs (activity, weight, eye gum, hair, feeding, excrement), head scratch frequency and image collection were observed to analyze the changes in biological signs of stasis syndrome (tongue image RGB), thrombin and serotonin of model rats.

RESULTThe reserpine group and the reserpine plus rheumatism model group showed significant reduction in blood coagulation time, pain threshold and 5-HT content in blood and brain (P < 0.01); the reserpine plus rheumatism model group showed an increase in eye gum and decreases in activity, feeding, with thin sloppy stool. According to the tough RGB values, the control group showed light red toughs, the reserpine group showed dark purple toughs, the reserpine plus rheumatism model group showed gray toughs, with notable differences in tough RGB values in all three group.

CONCLUSIONThe rheumatism stimulation with manual climate box, 5-HT reduction caused by reserpine and local cerebral vasospasm can be used to induce the migraine rheumatism stasis syndrome animal model, but its modeling assessment method and process shall be further improved.

OBJECTIVETo compare the clinical effects between hip anterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery and posterior K-L approach combined with quadratus femoris bone flap transplantation for the treatment of femoral neck fracture of Garden III-IV in young and middle-aged patients.

METHODSFrom January 2004 to January 2011,46 patients with femoral neck fractures were treated by two kinds of operation. Among them, 20 cases were treated with anterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery, included 12 males and 8 females with an average age of (32.1 ± 7.3) years old, involved 12 cases of Garden III and 8 cases of Garden IV. The other 26 cases were treated with posterior K-L approach combined with quadratus femoris bone flap transplantation, included 20 males and 6 females with an average age of (37.8 ± 6.9) years old, involved 16 cases of Garden III and 10 cases of Garden IV. The index of hospitalization (hospitalization time, total cost, operative time, intraoperative blood loss, postoperative complications), the quality index of operation (fracture reduction, position of internal fixation, fracture healing time, nonunion and femoral head necrosis) of two groups were observed and compared. Hip joint function were evaluated by Harris score.

RESULTSAll patients were followed up from 28 to 41 months with an average of 36 months. The intraoperative blood loss of group S-P (92.3 ± 10.4) ml was less than that of group K-L (132.4 ± 11.2) ml, there was significant difference between two groups (P < 0.05). The operation time of group S-P (81.4 ± 9.2) min was more than that of group K-L (67.1 ± 4.5) min, the difference was statistically significant (P < 0.05). One case in group S-P and 9 cases in group K-L appeared postoperative complications, there was significant difference between two groups (P < 0.05). The fracture healing time of S-P group (83.5 ± 7.3) d was shorter than that of group K-L (103.2 ± 12.6) d, there was significant difference between two groups (P < 0.05). At 30 months after operation, there were significant difference in Harris scoring between two groups (P < 0.05).

CONCLUSIONAnterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery for treatment of femoral neck fracture of Garden III-IV of young and middle-aged patients, it has characteristics in clear anatomic and easy to operate. As compared with K-L approach, S-P approach can better reserve residual blood supply of femoral neck. While combining with the iliac bone flap transplantation with deep circumflex iliac artery, it could better reconstruct the blood supply of femoral neck to promote fracture healing.

OBJECTIVE: To investigate the apoptosis of human breast cell line MCF-7 cells induced by gemcitabine and radiation. METHODS: The MTT method was applied to study the growth inhibition of MCF-7 treated with gemcitabine, radiation, gemcitabine and radiation. The apoptosis index (AI) was analyzed by flow cytometry. The morphology of the MCF-7 cells apoptosis was observed by transmission electron microscopy. RESULTS: When MCF-7 cells were treated with gemcitabine at different concentrations for 24 h, the cell growth inhibition rate was increased in a concentration-dependent manner. The apoptotic indexes (AI) of MCF-7 of four groups by flow cytometry revealed. The AI of (R+D) group was significantly different from those of the radiation group and the gemcitabine group (P<0.05). Condensed chromation, nuclear fragmentation and apoptotic body of MCF-7 cells were found by transmission electron microscope. CONCLUSION The apoptosis of human breast cancer cell line, MCF-7 cells, could be induced by gemcitabine. Gemcitabine can significantly enhance the radiation-induced apoptosis of MCF-7 cells.

AlM: To study the clinical effect of the application of microscopic pterygium resection combined with different concentration of mitomycin C ( MMC) .
METHODS:A total of 110 cases of pterygium patients (120 eyes) were randomly divided into control group (58 eyes) and observation group (62 eyes) according to the odd and even number method. The control group adopted the pterygium resection combined 0. 3mg/mL MMC, and the observation group was given pterygium resection combined 0. 2mg/mL MMC. The cure rate and the recurrence rate, eyesight before and after the treatment, two groups of cornea and sclera wound healing situation, the incidence of postoperative complications were compared.
RESULTS: The cure rate and recurrence rate of the control group was 84. 5% and 15. 5% respectively, and the observation group was 93. 6% and 6. 5% respectively, the differences were statistically significant (P<0. 05). There were statistical differences of vision of the two groups before and after treatment (P<0. 05), and there were no statistical differences of the two groups between the two groups after treatment (P>0. 05). The cornea, sclera, wound healing time of the observation group were less than the control group, and there were statistical differences between the two groups ( P < 0. 05 ). The incidence of complications was 13. 8% in the control group and 3. 2% in observation group, with statistically significant difference (P<0. 05).
CONCLUSlON: The application effect of microscopic pterygium resection combined with MMC is remarkable, and the joint of 0. 2mg/mL concentration of MMC is more safe and effective, and is worth popularizing in clinical application.

Objective: To evaluate the effects of sevoflurane on the dose-response relationship and on the timecourse of recovery of rocuronium. Method: Sixty patients,ASA grade Ⅰ,aged 18 to 52 years, undergoing elective plastic surgery,were included in this study. Patients were equally allocated randomly to either the control or the sevoflurane group. Anesthesia was maintained with 60％ N_2O-O_2-thiopental in the control group,and with 1 MAC sevofurane-N_2O-O_2 in the sevoflurane group. The dose-response relationship of rocuronium was established with a cumulative dosing regimen. Result: The dose response curve of rocuronium in the sevoflurane group was shifted to the left. The ED_(50),ED_(90) and ED_95 of rocuronium were decreased by 31％, 27％ and 25％, respectively in sevoflurane group as compared with those of the control group. Following an intravenous administration of rocuronium 400ug/kg,the duration of peak effect,duration of clinical relaxation,recovery index,and the total duration of action in the sevoflurane group were significantly prolonged vs. the control group. Conclusion: Sevoflurane can significantly enhance the neuromuscular blockade effect of rocuronium and prolong its duration of action.

OBJECTIVE: To explore the effect of polygonum multiflorum thunb (PMT) on the expression of brain-drived neurtrophic factor (BDNF) in hippocampus CA1 in rats induced by Abeta1-40. METHODS: The rat model was established by injecting Abeta1-40 into the right dorsal hippocampus in rats, and their behavior was observed by Y-maze. The morphological changes of rat hippocampus were examined by the Nissl staining. The expression of BDNF in hippocampus CA1 neurons was also examined by immunohistochemistry and Western blot. RESULTS: After the administration of Abeta1-40, the times of rats learning how to elude electric stimulation were significantly increased, and the expression of BDNF in hippocampus CA1 were obviously reduced. The aggregation of Abeta1-40 in hippocampus and the morphological changes of CA1 hippocampus were found. After the treatment with PMT for 30 days, the times learning how to elude electric stimulation were obviously reduced, while the expression of BDNF in hippocampus CA1 was also increased. CONCLUSION PMT can reverse the down-regulation of BDNF expression in hippocampus CA1 induced by Abeta1-40.
