Objective To investigate the effect of salvia mihiorrhiza on spinal cord ischemia reperfusion injury after surgical treatment in patients with cervical canal stenosis. Methods Retrospective analysis of 64 cases had cervical canal stenosis in the last 5 years in our hospital. Sixty-four cases were randomly divided into the salvia mihiorrhiza group(31 cases)and the control group(33 cases). The therapeutic effect was assessed using JOA grade system. Results In the salvia mihiorrhiza group,the JOA average score was 8. 8 ±2. 6 before surgical treatment, after two weeks of surgical treatment it was 13. 7 ± 2. 4. The JOA improvement ratio was (61. 5 ± 2. 9) % . In the control group,the JOA average score was 9. 1 ±2. 2 before surgical treatment,after two weeks of surgical treatment it was 13. 4 ± 2. 3. The JOA improvement ratio was (60. 5 ± 2.2)% .The JOA improvement ratio in the salvia mihiorrhiza group was significantly higher than that in the control group (P < 0. 05) . Conclusions Salvia mihiorrhiza has protective effect on spinal cord ischemia reperfusion injury.

Objective To investigate the protective effect of transection of cervical sympathetic trunk (TCST)on the fetal brain in rats with pregnancy-induced hypertension(PIH).Methods Thirty-two pregnant Wistar rats were randomly divided into 4 groups(n=8 each):A control group;B PIH group;C TCST+PIH group and D sham operation+PIH group,PIH was produced by L-NAME 12.5 mg?100g~(-1) given subcutaneously from 14~(th)-20~(th) day of gestation.In group A normal saline was given instead of L-NAME.In group C TCST was performed on the 14~(th) day of gestation and L-NAME was injected asin group B.In group D the cervical sympathetic trunk was only exposed but not cut.Caesarean section was performed and fetus was taken on the 21~(st) day of gestation.The ultrastructure of fetal brain was examined.The content of ATP,ADP and AMP in the fetal brain and the Na~+-K~+-ATPase and Ca~(2+)-ATPase activity in neuronal plasmalemma were determined.Results The ultrastructure of the fetal brain was almost normal in group A and C,but was seriously damaged in group B and D.The ATP and adenylic acid content in the brain tissue and the Na~+-K~+-ATPase and Ca~(2+)-ATPase activity in neuronal plasmalemma were significantly lower in group B and D than in group A and C.Conclusion TCST has protective effect on the fetal brain in rats with PIH by improving energy supply and enhancing pump function of neuron.

Objective To study the MRI manitestation of juvemle acute pure cartilage fracture of the knee joint.Methods The MRI changes of cartilage,subcartilage low signal line and subcartilage bone were analysed retrospectively in 26 juvenile patients with acute pure cartilage fracture confirmed by arthroscopy.Sagittal and coronal MRI scanning were performed in 26 patients.Using fast low angle shot fat saturation T_1-weighted image(FLASH-FS-T_1WI)sequences,spin echo T_1-weighted image(SE-T_1WI)and fast imaging with steady-state precession three dimensional fat saturation T_2-weighted image(FISP-3D-FS- T_2WI)sequences in sagittal plane,SE-T_1WI and multi echo data image combination T_2-weighted imaging (MEDIC or ME-T_2WI)in coronal plane.Using ME-T_2WI sequence,axial plane MRI scanning in 5 patients.Results Twenty-seven sites of 26 patients include 8 patella,7 femoral medial condyle, 11 femoral lateral condyle and 1 tibial plateau.Three types pure cartilage fracture were observed,totally defect of the cartilage in 7 sites(include 3 patella,2 femoral medial condyle,1 femoral lateral condyle and 1 tibial plateau),fissuring fracture in 3 sites(include 2 femoral medial and 1 femoral lateral condyles), superficial defect of the cartilage in 17 sites(include 5 patella,3 femoral medial and 9 femoral lateral condyle).Corpus liberum was found in 21 patients'knee joints by arthroscopy,but only 3 cases by MRI. Bone bruise was detected,and subcartilage low signal lines were normal.Conclusion Using FLASH-FS- T_1WI,SE-T_1WI,FISP-3D-FS-T_2WI and ME-T_2WI sequences,sagittal and coronal MRI scanning in femoral and tibial plateau pure cartilage fractures,and using ME-T_2WI sequence axial scanning in patella r cartilage fractures may show the position,extension and types of the acute pure cartilage fracture of the knee joint. MRI is the hest non-invasive method for studying cartilage fracture.

Background and purpose:The aim of this study was to analyze the prognostic factors in uterine adenocarcinoma and adenosquamous carcinoma treated with a combination of neoadjuvant chemoradiotherapy and surgery.Methods:Clinicopathologic data from 50 patients with stageⅠB2-ⅡA2 uterine cervical cancer were collected from the First Afifliated Hospital of Bengbu Medical College between Apr. 2005 and Oct. 2011. All patients underwent neoajuvant chemoradiotherapy, followed by radical hysterectomy and pelvic lymph node dissection. Before surgery, an intravenous chemotherapy was given. A particular vaginal brachytherapy was given to those with tumor diameter≥6 cm. The survival and recurrence in patients were analyzed retrospectively to investigate the prognostic factors. Results:In 50 patients withⅠB2-ⅡA2 uterine adenocarcinoma and adenosquamous carcinoma, 15 died during the follow-up period. The 2-year and 5-year progression-free survival rates were 80.12% and 72.24%, respectively, and median progression-free survival was 68 months. The 2-year and 5-year overall survival rates were 95.38% and 73.56%, respectively, and median overall survival was 80 months. Univariate analysis revealed that pelvic lymph node metastasis, cervical stromal invasion, parametrial infiltration, tumor diameter reduction <3 cm and advanced stage were the prognostic factors in patients with cervical cancer (P<0.05). Age, postoperative radiochemotherapy, lymphatic clearance involvement, FIGO stage, preservation of ovary and pathologic type were not associated with prognosis (P>0.05). Multivariate Cox proportional analysis revealed that pelvic lymph node metastasis and tumor diameter reduction after radiation and chemotherapy were the independent prognostic factors in patients with cervical cancer. Conclusion:The combination of neoadjuvant chemotherapy and surgery improves the resectable rate of patients withⅠB2-ⅡA2 uterine adenocarcinoma and adenosquamous carcinoma. Pelvic lymph node metastasis and tumor diameter reduction after radiation and chemotherapy are the independent prognostic factors in patients with cervical cancer.
