Objective To explore techniques of endoscopic ultrasonography for nasal cavity and its accuracy. Methods Under the guidance of nasal endoscope, ultrasonography of nasal cavity was performed by using a 10 MHz,3. 3 mm section probes. Thirty nasal cavities of 15 normal canine were scanned under general anesthesia. The sink experiment was used to decrease the influence of the ultraphonic artifact and to correct the data error. Results In gray scale ultrasound,most mucous and submucous tissue within nasal cavity were hypoechoic, the septal cartilage was echoless, and the cartilaginous membrane of the septal cartilage showed a consecutive hyperechogenicity line. The average thickness of the nasal septum and the average thickness of the inboard mucous and submuous of the inferior turbinate were (1. 87 0. 33)mm and (2.96 0.36) mm respectively. The rich blood flowing signals were observed by CDFI in soft tissues mentioned above. Pulsed Doppler of the nasal septum showed a venous waveform with the velocity ranging from 3. 1 to 13.8 cm/s and the arterial waveform with the peak systolic velocity of 10 to 54.8 cm/s, resistance index ranged from 0. 31 to 0. 57. Pulsed Doppler of the inferior turbinate showed a venous waveform with the velocity ranging from 4. 0 to 17. 3 cm/s and the arterial waveform with the peak systolic velocity of 7.5 to 79.6 cm/s, resistance index ranged from 0.25 to 0.62. Conclusions With correction factor,nasal endoscopic ultrasonography was accurate in localizing structures with clear images and high resolution. It could be a new imaging modality of diagnosing nasal mucosal and submucosal disorderes.

Objective:To study the effect of Jianpi Qinghua Recipe ( JPQHR) on angiotensin II/NADPH oxidase pathway in 5/6 nephrectomized rat renal failure model and the underlying mechanisms.
Methods:The animals were divided into 4 groups:the sham-operated group, the renal failure group, the JPQHR-treated group and the losartan-treated group. After 60-days therapy, serum nitrogen and creatinine were measured. The expression of angiotensin II type 1 receptor (AT1) protein and the expression of p47phox mRNA in renal tissue was determined. SOD and MDA were also examined.
Results:Compared with the sham-operated group, the levels of SCr and serum BUN and the AT1 protein and p47phox mRNA expression in the renal failure group were significantly increased. hTe activities of SOD in renal tissue from the renal failure group was signiifcantly down-regulated while MDA was up-regulated (P<0.05). Compared with the renal failure group, the levels of SCr and serum BUN and the AT1 protein and p47phox mRNA expression in both JPQHR-treated group and losartan-treated group were signiifcantly decreased. hTe activities of SOD in renal tissue from JPQHR-treated group and losartan-treated group were signiifcantly up-regulated whereas the content of MDA were down-regulated (P<0.05). Compared with the losartan-treated group, the activities of SOD in renal tissue from the JPQHR-treated group was obviously increased (P<0.05), the decrease in AT1 protein and p47phox mRNA was more evident but not statistically different (P>0.05). The level of SCr and serum BUN and the content of MDA were also not statistically different (P>0.05).
Conclusion:hTrough decrease the expression of angiotensin II and NADPH oxidase, JPQHR can reduce the oxidative stress in chronic renal failure and delay the renal ifbrosis progression.

Objective:To explore the protective effect of vagus nerve stimulation (VNS) on the prognosis of rats suffering from cardiac arrest/cardiopulmonary resuscitation (CA/CPR) under different treatment timings.Methods:The method of percutaneous epicardial electrical stimulation was used to establish CA model of rat. Fifty-three male SD rats were randomly (random number) divided into the sham group ( n=5), CPR group ( n=12), PRE group ( n=12), POST5 group ( n=12) and POST30 group ( n=12). The sham group did not experience CA/CPR. VNS treatment was started at 30 min before CA (PRE group, n=12), 5 min after recovery of spontaneous circulation (ROSC) (POST5 group, n=12), and 30 min after ROSC (POST30 group, n=12) in different VNS-treated group, respectively. The electrical stimulation was applied to the vagus nerve for 30 min with a unified parameter. The neurological deficit scores at 24, 48, and 72 h after ROSC were recorded, and the survival rate in each group was observed. TUNEL staining was used to detect the apoptosis of cortical area and the expression of α7 nicotinic acetylcholine receptor (α7nAChR) in brain tissue was measured by immunofluorescence at 72 h after ROSC. Variables were compared with one-way analysis of variance, and survival for Kaplan-Meier curves were tested with the log-rank test. A P value less than 0.05 was considered statistically significant. Results:Compared with the CPR group (survival rate 33.33%), both pre-treatment (survival rate 75%) and post-treatment of VNS (POST5 group survival rate 75% and POST30 group survival rate 83.33%) significantly improved the 72 h survival rate after CPR ( P<0.05), mitigated neurological deficits after ROSC, reduced the positive rate of apoptosis neurons, and up-regulated the expression of α7nAChR in cerebral cortex. There was no significant difference among the VNS-treated groups (all P>0.05). Conclusions:Both pre-treatment and post-treatment of VNS can play a protective role in rats after CA/CPR, which may be related to the activation of α7nAChR-mediated anti-inflammatory and anti-apoptosis effects.

OBJECTIVETo investigate the effect of apigenin on the protein expression levels of peroxisome proliferator-activated receptors (PPARs) in liver tissues of rats with nonalcoholic steatohepatitis (NASH).
METHODSThe NASH rat model was established by feeding of a high-fat diet. Unmodeled rats served as the normal controls. The modeled rats were divided into a model control group, Essentiale treatment grouP(300 mg/kg/day),and three apigenin treatment groups for low-dose (15 mg/kg/day), moderate-dose (30 mg/kg/day) and high-dose (60 mg/kg/day). After 13 weeks of treatment,changes in insulin sensitivity from pre-treatment baseline were assessed by measuring the alanine aminotransferase (ALT), aspartate aminotransferase (AST),total cholesterol (TC),triglycerides (TG),low-density and high-density lipoprotein cholesterol (LDL-C and HDL-C),fasting blood glucose (FBG) and fasting insulin (FINS).The liver index and HOMA-IR were also calculated.Protein and gene expression of PPARα and PPARgamma in liver tissue were assessed by immunohistochemistry and RT-PCR.Statistical analysis was performed by the LSD test and Games-Howell test.
RESULTSThe apigenin-treated groups showed a significantly greater change in insulin sensitivity than the untreated model group,with the most significant change occurring in the high-dose grouP(P less than 0.05).Compared with the untreated model group,the apigenin-treated groups showed lower levels of ALT (95.4+/-7.3),AST (183.7+/-14.3),TC (1.61+/-0.25),TG (1.23+/-0.21),LDL-C (1.86+/-0.14),FBG (5.29+/-1.45) and FINS (0.76+/-0.86),but a higher level of HDL-C (1.04+/-0.17); again,the high-dose group showed the greatest change (all P less than 0.05).Compared to the untreated model group,the apigenin-treated groups showed significantly lower liver index (3.75+/-0.25 vs.2.90+/-0.17) and HOMA-IR (1.34+/-0.06 vs.0.18+/-0.04),with the high-dose group showing the greatest change (both P less than 0.05). Compared to the untreated model group,the apigenin-treated groups showed higher levels of protein and mRNA of PPARα (18.27+/-4.05 and 0.63+/-0.02,respectively) and PPARgamma(8.48+/-5.05 and 0.39+/-0.02),with the high-dose group showing the greatest change (all P < 0.05).
CONCLUSIONApigenin can improve glucose tolerance,lipid metabolism and insulin resistance while decreasing blood levels of TC,TG,LDL-C,FBG,FINS and HOMA-IR,and increasing HDL-C in NASH,as shown in a high-fat diet induced rat model, and may have therapeutic potential.
