Objective To preliminarily explore the effects and brain protective mechanism of intermittent hypoxia preconditioning ( IHP) on rats with seizures induced by lithium-pilocarpine ( Li-pilo) .Methods A total of 96 8-week old male Sprague Dawley rats ( clean grade ) were randomly divided into control group , seizure group and four IHP-seizure groups.The animal model of epilepsy was established by intraperitoneal injection of Li-pilo in the seizure group and four IHP-seizure groups (Li-pilo was injected at 1, 3, 7, or 14 days after a 5-day regimen of IHP).Subsequent seizure behavior , the latency period and percentage of generalized seizures were quantitatively evaluated for 240 min and the cognitive function was tested by Morris water maze task , and followed by the detection of hippocampus neuron apoptosis and related protein (BCL-2, Bax, and cleaved-caspase-3) by TUNEL labeling and Western blot, respectively.Results The induced seizure peaked on an average between 50-150 min after Li-pilo administration , scored using a modified Racine scale.The average scores of modified Racine scale in the IHP-3d seizure group was significantly lower than that in the other groups.The latency period and percentage of generalized seizures in the IHP-3d seizure group rats were significantly different from the parameters in the seizure group rats (P<0.05).IHP-3d seizure rats showed lower escape latency, neuronal apoptosis counts and higher percentage of time in the probe quadrant compare with the seizure group and the other three IHP-seizure groups ( P <0.05 ) .Compared with the control group , the parameters of water maze and apoptosis detection in the IHP-3d seizure group showed no significant changes (P>0.05).Conclusions The results indicate that IHP treatment may help to decrease the susceptibility to epilepsy by reducing abnormal apoptosis , and has a brain protective effect on the seizure rats .

Objective To explore the clinical effects of S-1 single agent chemotherapy for the patients undergoing radical resection of cholangiocarcinoma.Methods The clinical data of 51 patients receiving radical resection of cholangiocarcinoma who were admitted to the Second Affiliated Hospital of Zhejiang University from November 2011 to December 2013 were retrospectively analyzed.After radical resection of cholangiocarcinoma,25 patients receiving non-special treatment and 26 patients receiving S-1 single agent chemotherapy were divided into the operation group and chemotherapy group,respectively.S-1 was taken orally twice per day.Forty mg/once of S-1 was applied to patients with the body surface area ＜ 1.25 m2,50 mg/once of S-1 was applied to patients with the body surface area ≥ 1.25 m2 and ＜ 1.50 m2,and 60 mg/once of S-1 was applied to patients with the body surface area ≥ 1.50 m2.The 14 days usage and 7 days withdrawal of S-1 were used as one course of treatment.The standard usage of S-1 was 6-8 courses of treatment.All the patients were followed up by outpatient examination and telephone interview till December 1,2014.Count data were analyzed using the chi-square test.Measurement data with normal distribution were presented as (x) ± s and analyzed using the t test.Survival curve was drawn by the Kaplan-Meier method,and survival analysis was done using the Log-rank test.Results Twenty-six patients in the chemotherapy group finished the courses of chemotherapy without chemotherapy-related death,and 14 patients had chemotherapy adverse reactions with remission after discontinuation of S-1.All the 51 patients were followed up for 5-37 months with a median time of 19 months.The median overall survival time,1-,3-year overall survival rates,tumor-free median survival time and 1-,3-year tumor-free survival rates were 22 months (range,18-27 months),72.3％,42.9％,21 months (range,16-26 months),60.0％,55.0％ in the operation group and 32 months (range,29-35 months),84.6％,44.4％,26 months (range,21-31 months),76.9％,61.9％ in the chemotherapy group,respectively.There was a significant difference in the overall survival between the 2 groups (x2=6.032,P ＜ 0.05).There was no significant difference in the tumor-free survival between the 2 groups (x2=0.498,P ＞ 0.05).Conclusion S-1 single agent chemotherapy after radical resection of cholangiocarcinoma could improve the survival of patients,while no obvious advantages of inhibiting tumor recurrence is observed.

BACKGROUND: Chronic osteomyelitis is difficult to manage clinically, and two or more operations were commonly needed. No satisfactory method for one-stage repair has been currently available.OBJECTIVE: To examine the possibility of using fibrin glue(FG) as the common carrier for both bone morphogenetic protein(BMP) and gentamicin for one-stage repair of infected bone defects.DESIGN: A completely randomized controlled experiment.SETTING: Center of Orthopaedic Surgery, Lanzhou General Hospital of Lanzhou Area Command of of Chinese PLA.MATERIALS: The experiment was conducted using 48 healthy adult Chinchilla rabbits of either sex on normal diet with body mass of 1.9 to 2.4 kg,provided by the Institute of Biological Products, Lanzhou, Gansu Province.INTERVENTIONS: Animal models of chronic osteomyelitis were established in 48 Chinchilla rabbits, and after thorough debriding of the wounds,an elongated semicircular bone defect was induced 1.5 cm to the medial proximal metaphysis in the tibias. Three treatments were subsequently given with FG, MP and gentamicin complex(Group A), FG/BMP complex(Group B), and nothing(control group, Group C), respectively.MAIN OUTCOME MEASURES: The general conditions of the rabbits were observed postoperatively. Bacterial culture of the bone specimen, bacterial counting, X-ray and histological examination were performed.RESULTS: Rabbits in Group A exhibited obviously better infection control and greater regenerated bone mass than those in Group B, and no significant difference was noted in infection control between Groups B and C, the latter group showing poor bone defect repair.CONCLUSIONS: FG, BMP and gentamicin complex helps to control infection and promotes bone formation, and can be used to repair bone defects caused by infection and open injury with severe contamination.

Objective To investigate the protective effect of icariin against varicocele-induced damage on rat epididymis. Methods Forty adolescent male SD rats were randomly divided into control group (n=10), experimental varicocele (EV) group (n=15), icariin (ICA) therapy group (n=15). Experimental varicocele model in the EV group and ICA group was established. The EV was induced by partial ligation of the left renal vein. The rats in the control group underwent a sham operation that separated the spermatic vessels without ligation. Each rat in the control group and EV group was lavaged with 2 mL physiological saline every day for 6 weeks. Each rat in the ICA group was lavaged with icariin [100 mg/(kg·d)] for 6 weeks. Rats in all groups were executed after 6 weeks. The contents of sialic acid were measured by spectrophotometry. Carnitine concentrations were measured by DTNB. HE stain was used to observe the microstructure changes in the epididymal tissue. Electron microscopy was used for observing the ultrastructural changes of the epididymis. Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) method was used to detect the apoptosis of the epididymal epithelium. Results Compared with the control group, the microstructure and ultrastructure of the epididymis in EV group showed pathological damage. Compared with the EV group, the damage of the epididymal microstructure and ultrastructure significantly alleviated. Apoptosis index (AI) of epididymal epithelium in the EV group was significantly higher than that in the control group (P<0.01). However, AI of epididymal epithelium in the ICA group was significantly lower than that in the EV group (P < 0.01). The sialic acid and carnitine concentrations of the epididymis in the EV group was significantly lower than that in the control group (P < 0.01), respectively. However, the sialic acid and carnitine concentrations of the epididymis in the ICA group was significantly higher than that in the EV group (P < 0.01), respectively. Conclusion This study indicates that varicocele could result in the apoptosis of epididymal epithelium and icariin decreased the varicocele-induced apoptosis , suggesting that varicocele could damage the structure and function of epididymis, which can be repaired by icariin.

Objective To evaluate modified laparoscopic hepatic hemangioma extraction methods during laparoscopic hepatectomy.Methods From May 2009 to June 2013, 25 hepatic hemangioma patients were admitted for laparoscopic hepatectomy.Patients were divided into modified laparoscopic group with modified laparoscopic hepatic hemangioma extraction methods (MLH, n =11) and traditional laparoscopic group (TLH, n =14).Perioperative clinical parameters were compared between the two groups.Results Operative time (148.6 ± 18.0) min, time to removal of the HCH (15.7 ±4.6) min, visual analog scale pain score on the first postoperative day (2.3 ± 0.9), time to off-bed activity (2.5 ± 0.8) d, and postoperative hospital stay (8.5 ± 2.6)d in the MLH group were all less than those in the TLH group [(163.9±13.2)min, (33.9±3.1)min, (3.4±0.9), (3.1±0.8)d, (10.6±1.9)d] (t=-2.451,t =-11.800, t =-2.931, t =-2.156, t =-2.338,P ＜ 0.05).There were one in the MLH group and two cases in the TLH group developing postoperative complications (P =1.000).Conclusions Modified laparoscopic hepatic hemangioma extraction methods during laparoscopic hepatectomy for hepatic hemangioma is safe, feasible and of good therapeutic effect.
