Objective To evaluate the effect of dexmedetomidine on autophagy in the hippocampal neurons of rats with traumatic brain injury (TBI).Methods Adult male Sprague-Dawley rats,aged 12-16 weeks,weighing 340-370 g,were randomly divided into 3 groups (n=80 each) using a random number table:sham operation group (group S),traumatic brain injury group (group TBI) and dexmedetomidine group (group Dex).The rats were subjected to a diffuse cortical impact injury caused by a modified weight-drop device to induce TBI.Dexmedetomidine 15 μg/kg was injected intravenously immediately after TBI in Dex group.At 24 and 48 h after TBI,neurological deficit score (NDS) was assessed,Morris water maze test was performed,and brains were removed for detection of brain water content in the brain tissue.At 6,12,24 and 48 h after TBI,the expression of hippocampal LC3]Ⅱ was determined using Western blot analysis.Results Compared with group S,brain water content and NDS were significantly increased at 24 and 48 h after TBI,the escape latency was prolonged,and the expression of hippocampal LC3 Ⅱ was upregulated at 6,12,24 and 48 h after TBI in TBI group.Compared with TBI group,brain water content and NDS were significantly decreased at 24 and 48 h after TBI,the escape latency was shortened,and the expression of hippocampal LC3 Ⅱ was down-regulated at 6,12,24 and 48 h after TBI in Dex group.Conclusion The mechanism by which dexmedetomidine reduces TBI is related to inhibition of autophagy in the hippocampal neurons of rats.

Objective To study the clinical diagnosis and treatment of malignant gastrointestinal stromal tumor. Methods To retrospectively analyze the clinical data of 28 cases with malignant gastrointestinal stromal tumors underweat surgical treatment . Results The malignant gastrointestinal stromal tumor in adults were more than 50 years old,71.4%(20/28) ,and common clinical symptoms were gastrointestinal bleeding,anemia,and pain. The lesion site: 19 cases of gastric bowel, 8 cases of small intestine, 1 case of colon, radical excision in 22 cases, local excision palliative resection in 5 cases, three cases were multi-visceral resection. Conclusion Malignant gastrointestinal stromal tumor could be diagnosed by the means of endoscopic imaging and clear,and preoperative diagnosis was difficult. Surgical resection was the pathology diagnosis and treatment of primary method,if necessary,to ensure multi-visceral resection of the tumor to prevent recurrence of thoroughness, had important significance.

Objective To discuss the role of therapeutic drug monitoring (TDM) in pharmaceutical care by successful intervention of severe drug-drug interaction in 3 patients with hematological disease treated with voriconazole and rifampin.Methods Three patients with hematological disease were monitored for the plasma concentration of voriconazole before,during,and after the concomitant use of rifampin.The severity of this drug interaction was revealed,risks for developing invasive fungal infection and tuberculosis dissemination after chemotherapy were evaluated based on the TDM results,and alternative regimens were recommended.Results Voriconazole plasma concentration was normal at baseline but significantly depressed after combination with rifampin in all 3 cases.Concomnitant use of rifampin leads to a rapid decline in plasma concentration of voriconazole in 2-3 days,and withdraw of this enzyme induction effect takes 8-10 days after discontinuation of rifampin.Conclusion TDM is a helpful tool for providing pharmaceutical care,it helps to objectively visualize the degree of clinically important drug-drug interactions.Clinical evidence together with TDM results suggests high risk for developing invasive fungal infection and tuberculosis dissemination in hematology patients while using this combination therapy.Discontinuation of rifampin was suggested and accepted.For these patients,combination of voriconazole and rifampin should be avoided.

Objective To observe the changes of bone mass in reloaded rats after tail-suspension,and the effect and mechanism of simvastatin on this process.Methods Twenty-four 5-month old rats were divided into 4 groups of 6 animals in each group: Control (CL) group without tail-suspension,unloaded (UL) group with tail-suspension for 6 weeks,other 12 rats received tail-suspension for 3 weeks,then reloaded for subsequent 3 weeks (UL+RL) or combined with simvastatin treatment (UL+RL+SIM) at a dose of 10 mg/kg/d.All rats were sacrificed 6 weeks later,and the left femur was used for examination of bone mineral density,left tibia was used for bone histomorphometry analysis,the right femur and tibia were harvested for biomechanical test,and expression levels of type I collagen by real-time PCR and Western blot,respectively.Results 1.BMD of the CL group was significantly higher than those of the other three groups (P<0.05),and was markedly lower than those in the UL+RL and UL+RL+SIM groups (P<0.05).2.The bone histomorphometry showed that BV/TV in the CL group was significantly higher than those in the other 3 groups,and the UL+RL and UL+RL+SIM groups showed a significantly higher BV/TV than that of UL group (P<0.05).The Tb.Th was significantly higher in the CL group than in the UL group.The Tb.Sp in the CL group was significantly lower than those in the other 3 groups (P<0.05).The UL+RL and UL+RL+SIM groups showed significantly lower Tb.Sp than that of the UL group (P<0.05).3.Biomechanical test showed that the maximal load and elastic modulus in the CL groups were significantly higher than those of the other three groups (P<0.05).4.Real-time PCR showed that no significant difference in the mRNA expression level of Col I was found between any two groups.5.Western blot showed that the IOD of Col I is significantly lower than that in the CL group.Conslusions Bone loss,destruction of trabecular bone micro-architecture and biomechanical properties and reduction of type 1 collagen are present in tail-suspension treated rats,which are partially restored after reloading,and this recovery process is not enhanced by simvastatin treatment.

The traditional Chinese medicine (Tripterygium wilfordiiHook.f.,TWH) has been clinically used to treat primary and secondary renal diseases and proteinuria for nearly 40 years.However,there is a rare literature about the effect of triptolide (the main active ingredient of TWH) on the expression of oxidative carbonyl protein (OCP) in diabetic nephropathy (DN).This study aimed to provide experimental evidence for triptolide treatment on DN through its effect on the expression of OCP,in order to investigate the effects of triptolide on the expression of OCP in rats with DN.Sixty SD rats were randomly divided into five groups:control group,high-dose triptolide (Th) group,low-dose triptolide (T1) group,DN model group,and positive control (benazepril) group.The DN model was established using streptozotocin.Urinary protein excretion,fasting blood glucose (FBG),superoxide dismutase (SOD) in renal homogenate,malondialdehyde (MDA) in renal homogenate and renal nitrotyrosine by immunohistochemistry,and the expression of OCP by oxyblotimmune blotting were detected.In the DN model group,rat urinary protein excretion and renal MDA were significantly increased,while renal SOD significantly decreased and nitrotyrosine expression was obviously upregulated in the kidney.After triptolide treatment,24-h urinary protein excretion (61.96±19.00 vs.18.32±4.78 mg/day,P＜0.001),renal MDA (8.09±0.79 vs.5.45±0.68 nmol/L,P＜0.001),and nitrotyrosine expression were decreased.Furthermore,renal OCP significantly decreased,while renal SOD (82.50±19.10 vs.124.00±20.52 U/L,P＜0.001) was elevated.This study revealed that triptolide can down-regulate the expression of OCP in the renal cortex of DN rats.
