This study was aimed to investigate the effects of Chai-Hu Shu-Gan Tang (CHSGT) on levels of TNF-α and 5-HT in lithium chloride–pilocarpine caused epilepsy–depression comorbidity rat model, in order to discuss the intervention effect of CHSGT on TNF-α and 5-HT in epilepsy–depression comorbidity. The lithium chloride–pilocarpine caused epilepsy–depression comorbidity rat model was established. After 6 weeks of animal establishment, rats were randomly divided into 5 groups, which were citalopram group (A), physiological saline group (B), CHSGT high dose group (C), medium dose group (D), and low dose group (E). Intragastric administration was given for 4 weeks, twice a day. Before and after the treatment, RT-PCR was performed to detect hippocampal TNF-αlevels. Liquid chromatography-mass spectrometry was performed to detect hippocampal 5-HT levels. Both forced swimming test (FST) and saccharin preference test were carried out to monitor the depressive behaviors of rats. In the meantime, 24 hours a day video camera surveillance were performed to record the number of seizures of rats. The results showed that after treatment, the number of seizures of rats were significantly reduced, the accumulative immobility time in FST was shortened, and the consumption of sucrose increased significantly (P < 0.01) in group A, C and D. Compared with group B, after the treatment, the expressions of hippocampal TNF-α mRNA of rats in group A, C, D were distinctly downregulated, with the level of 5-HT significantly increased (P < 0.05,P < 0.01). Compared with group A, group C and D showed no significant changes. It was concluded that TNF-α played a role in the pathogenesis of epilepsy–depression comorbidity through mediating the level of 5-HT. High and medium doses of CHSGT can downregulate the expression of TNF-α mRNA in depression comorbidity of chronic temporal lobe epilepsy, increase 5-HT level, reduce the number of seizures of rats, and improve depressive behaviors.

BACKGROUND: There are few reports about vascularization in the repairing of bone defect by heterogeneous deproteinized bone.OBJECTIVE: To verify the vascularization characteristics of heterogeneous deproteinized bone, tissue engineering scaffold material, in the repairing of large segmental bone defect.DESIGN, TIME AND SETTING: The randomized controlled animal experiment was performed between March 2005 and February 2007 at the Third Military Medical University, Chongqing, China.MATERIALS: Twenty-four 10 to 12 months old goats, weighing (22.5±2.5)kg, were obtained from the Animal Center of the Third Military Medical University, Chongqing, China. Segmental bone defects of 20 percent right tibia middle and inferior diaphysis of the 24 goats were made.METHODS: The 24 goats were divided into test group (n=16) and control group (n=8) randomly. Goats in test group were implanted with deproteinized bone+autologous MSCs+recombinant human bone morphogenetic protein-2 (rhBMP-2), goats in control group were implanted with autograft bone, and all fixed with half-ring sulcated external fixator. Every 4 weeks, 3 goats were killed after ink perfusing through femoral artery. A thick slice of new bone tissue was made to observe the vascularization.MAIN OUTCOME MEASURES: Vascularization of new bone observed through gross anatomy and imaging; vascular network of new bone observed through thick section, blood vessel amount and area measured by Image-proplus really image analysis software.RESULTS: No goat was infected or dead. Animal soft tissue was dyed black, blood vessels'size, ditribution and network structure were observed in subcutaneous tissue, fascia and periosteum. At 4 weeks postoperation implant margin became crude in the defect area; at 8 weeks postoperation transparent bone absorbing area of different size and irregular shape appeared; after 12 weeks postoperation high-dense calcification shadow appeared at the ends of defect bone and new bone connected with the ends completely. On 4 to 24 weeks postoperation, the blood vessel amount became large, alignment became regular, and their size and distribution became uniform. It showed no significant difference in blood vessel amount and area between 2 groups (P>0.05).CONCLUSION: Composite of heterogeneous deproteinized bone+autologous MSCs+rhBMP-2 has the same vascularization degree. of autogeneous bone graft in repairing of large segmental tibia defect.

Objective:
To investigate the effectiveness of preoperative 3D-CTA in assisting the preparation of free thinned anterolateral thigh lobulated perforator flap with nerve in repairing soft tissue defect of limb.
Methods:
Between February, 2010 and May, 2018, free super-thin anterolateral thigh lobulated perforator flap with nerve was transferred to repair soft tissue defect of limbs in 11 cases. There were 8 males and 3 females with an average age of 35 (range, 22-56) years. The defect area was 8.0 cm×11.0 cm-9.0 cm×23.0 cm. Preoperation CT scan of the free flap donor site was performed to obtain 3D images of the region with arterial blood supply by digital 3D reconstruction CT, and to determine the origin, direction, classification, length, diameter and the position of pedicle perforator. Postoperative regular followed-up was carried according to the Upper Limb Function Evaluation Trial Standards of Chinese Medical Association of Hand Surgery and Enneking Evaluation System.
Results:
All 11 flaps survived. No vascular crisis happened. All 11 cases were followed-up for 3 to 12 (average, 5) months. The flaps were supple and elastic with near normal color. There was no bulkiness. Sensory function was recovered well and two point discrimination was 3.0-6.0 mm. According to the Upper Limb Function Evaluation of Upper Limb of Chinese Medical Association of Hand Surgery, the results were excellent in 1 case, good in 3 cases and fair in 1 case. The Enneking system was used to assesse the lower limbs recovery. The average score was 21, an average of 70% of limb function restored.
Conclusion
The free super-thin anterolateral thigh lobulated perforator flap with nerve offers advantages to the traditional anterolateral thigh flap. The survived flaps are ideal in terms of covering limb defects and restoring functions. Preoperative 3D-CTA in the anterolateral thigh perforator flap transplantation is an accurate and useful method. It helps a safer and successful operation with optimal outcome.
