ObjectiveTo observe the effect of Liuwei Dihuangwan on behavioral impairments in the rat model of autism spectrum disorder (ASD) and explore the mechanism of action. MethodsTwelve SD pregnant rats were intraperitoneally injected with valproic acid (VPA) (10 rats) or normal saline (2 rats), and male offspring were selected to establish the model of ASD and the control rats. Rats were randomly assigned into model, low-dose (0.75 g·kg-1) and high-dose (1.5 g·kg-1) Liuwei Dihuangwan, vitamin D (positive drug, 3.7×10-5 g·kg-1), and blank groups. Each group was administrated with the corresponding concentration of drugs or the same volume of normal saline by gavage for 2 weeks. After the intervention, the three-chamber social test was conducted to evaluate social interaction and social preference. The open field test was carried out to observe spontaneous behavior and anxiety state. Hematoxylin-eosin staining (HE) was used to observe the pathological changes of the prefrontal tissue. Transmission electron microscopy was employed to observe the ultrastructure of mitochondria in prefrontal neurons. Immunofluorescence was used to detect the expression of ionized calcium-binding adapter molecule-1 (Iba-1) in the prefrontal tissue. Enzyme-linked immunosorbent assay (ELISA) was adopted to measure the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). Western blot was employed to assess the expression differences of phosphorylated adenosine monophosphate-activated protein kinase (p-AMPK), adenosine monophosphate-activated protein kinase (AMPK), phosphorylated Unc-51-like autophagy-activating kinase 1 (p-ULK1), Unc-51-like autophagy-activating kinase 1 (ULK1), and FUN14 domain-containing protein 1 (FUNDC1). ResultsCompared with the blank group, the model group spent less time sniffing stranger 1 and stranger 2 in the three-chamber social test (P<0.01) and showed reductions in the total distance traveled, average speed, distance traveled in the central area, and time spent in the central area in the open field test (P<0.01). In addition, the model group showed extensive apoptosis of neurons, with shrunken nuclei and red-stained cytoplasm, and extensive necrosis of neurons in the prefrontal tissue, mitochondrial swelling, decreased matrix density, disrupted cristae, and autophagic lysosomes in neurons, increases in the rate of Iba-1 positive cells in the prefrontal area (P<0.01) and the levels of TNF-α and IL-6 (P<0.01), and down-regulation in the expression of p-AMPK/AMPK, p-ULK1/ULK1, and FUNDC1 (P<0.01). Compared with the model group, low-dose and high-dose Liuwei Dihuangwan and the vitamin D prolonged the time spent sniffing stranger 1 and stranger 2 in the three-chamber social test (P<0.05, P<0.01), increased the total distance traveled, average speed, distance traveled in the central area, and time spent in the central area in the open field test (P<0.05, P<0.01), restored the morphology of neurons in the prefrontal tissue, decreased the number of apoptotic cells, alleviated the swelling of mitochondria in neurons, increased the matrix density, mitigated the fragmentation and disorder of cristae, and increased the number of autophagosomes. Moreover, the drugs decreased the rate of Iba-1 positive cells in the prefrontal area (P<0.01), lowered the levels of TNF-α and IL-6 (P<0.01), and up-regulated the expression of p-AMPK/AMPK, p-ULK1/ULK1, and FUNDC1 (P<0.01). ConclusionLiuwei Dihuangwan ameliorate autism-like behaviors and reduce neuronal apoptosis and neuroinflammatory damage in the rat model of ASD by promoting mitophagy mediated by the AMPK/ULK1/FUNDC1 pathway.

Objective To evaluate the effect of mental intervention combined with simple brachial plexus anesthesia in children' upper extremity operation. Method 80 cases of8 ~ 12 years old children were selected after strict evaluation and screening,of who needed upper extremity operation(fractures internal fixation not included) ,and the surgery time less than 120 minutes. All the operations were completed under the simple brachial plexus anesthesia, and combined with mental intervention preoperatively and intraoperatively. The changes of HR and BP intraoperatively the psyche condition after the operation completed were observed and followed up the mental change postoperatively. Result All the operation were completed. The HR and BP were stable intraoperation (P > 0. 05), the psyche was quiet after the operation completed,and no mental disorder was happened postoperative. Conclusion The mental intervention combined with simple brachial plexus anesthesia was safe in 8 ~ 12 years old children' upper extremity operation, and it deserved to spread and apply.

Objective To explore the etiopathogenisis of Reinke's edema. Methods To detect 15 samples of Reinke's edema of vocal cord mucosal and 5 samples of common vocal cord mucosal with S-P immunohistochemical method. Then to observe the effect of immunity class under the light microscope. To detect the expression of the VEGF and the production of the blood capillary in the sample of Reinke's edema of vocal cord mucosal with immunohisto-chemical method. Results There are 12 effects of sex in the 15 samples of Reinke's edema of vocal cord mucosal. There are effects of feminine in the 5 samples of common. Conclusion The main etiopathogenisis of Reinke's edema is that blood vessel grew ad libitum, the permeability of blood vessel increase and oxygen lack partly.

Objective To determine the effects of different anesthetic techniques on T-lymphocyte subsets in patients with esophageal carcinoma. Methods Forty patients were randomly assigned into general anesthesia group (group Ⅰ),or combined generae anesthesia with epidural anesthesia group(group Ⅱ). Peripheral blood CD3, CD4,CD8 were measured before induction ( T1 ), after anesthesia ( T2 ), end of operation ( T3 ), 1d ( T4 ), 3d ( T5 ) after surgery. Resolts CD3,CD4,CD8,CD4/CD8 decreased at T2 in the two groups. In group Ⅱ ,CD3,CD4,CD8,CD4/CD8 ratio almost returned to the baseline values at T4 ,while group Ⅰ did not. Conclusion Epidural anesthesia combined with general anesthesia can reduce depression of T-lymphocyte subsets induced by surgical trauma and anesthesia, and is the anesthetic tecnique of choice for cancer patients undergoing major operation.
