Objective To investigate the acoustic characteristics of snoring sound in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and with simple snoring. Methods 22 patients with OSAHS and 15 with simple snoring were included in this study. Natural overnight snoring was digitally recorded and portable sleep mo-nitoring was performed simultaneously. 10 snores, which were the 1st snores after 10 cycles of obstructive apnea, from each patient in OSAHS group, and 10 snores from each patient in simple snoring group were analyzed in the time and frequency domains. Results The sound waves of snoring in the two groups exhibited different patterns both in the time and frequency domains. The snoring spectrum of patients with simple snoring showed distinct fun-damental- harmonic structures which were not clear in patients with OSAHS. The central frequency of the patients with OSAHS was higher, and 800 Hz power ratio was lower than those of the patients with simple snoring. In the OSAHS group, the central frequency of the patients with moderate-to-severe OSAHS was higher, and 800 Hz power ratio was lower than those of the patients with mild OSAHS. The differences of the two parameters were of statistical significance. Conclusion The snoring sounds in patients with OSAHS and with simple snoring have dif-ferent characteristics in time and frequency domains, indicating that it is feasible to research the OSAHS by way of snore monitoring and analyzing technique.

BACKGROUND:Coronary stent implantation can cause blood vessel damage and wal reconstruction, leading to vascular stent restenosis. Studies have found that visfatin is associated with inflammatory reaction, and exhibits an increased expression at the site of plaque rupture in acute myocardial infarction. OBJECTIVE:To investigate the influence of percutaneous coronary intervention on the levels of visfatin in patients with coronary heart disease. METHODS:Thirty patients with acute myocardial infarction within 12 hours after the onset of the chest pain, 30 patients with unstable pectoris and 30 patients with stable angina pectoris were included. Al patients were successfuly treated by percutaneous coronary intervention. Meanwhile, 30 patients only undergoing coronary angiography but not stenting treatment were selected, and another 30 patients without any treatment served as normal control group. RESULTS AND CONCLUSION:According to enzyme-linked immunosorbent method, the visfatin levels of acute myocardial infarction, unstable angina, stable angina and coronary angiography groups continue to rise at pre-operation, 30 minutes, 6 hours, 12 hours, 24 hours after operation, al of which were higher than that in the normal control group (P < 0.05). The results confirmed that within 24 hours after coronary stent implantation the visfatin levels continue to rise.

Objective To investigate the effects of electroacupuncture (EA) on the implementation of blind nasojejunal (NJ) tube placement and enteral nutrition (EN) in neurosurgical severe coma patients in intensive care unit (ICU).Methods Seventy-nine neurosurgical severe coma patients admitted to ICU were randomly divided into conventional group (blind NJ tube placement,n =40) and EA group (NJ placement and EA,n =39).EA was performed after NJ tube placement at bilateral acupoints Zusanli (ST36) and Hegu (L14) points using EA treatment instrument.The impelling distance of NJ tube were measured and the success rate of NJ tube placement were calculated.The postoperative complications were observed.Results The difference of NJ tube impelling distances at the 24th,48th,and 72th hours after surgery in EA group were significant longer than that in conventional group (P ＜ 0.05).The success rates of NJ tube placement at the 24th and 72nd hours after surgery in EA group were significantly better than that in conventional group (P ＜ 0.05).Their EN calories qualifiedness rate in 72 hours also increased significantly compared with conventional group and the proportion of patients assisted with parenteral nutrition decreased (P ＜0.05).The postoperative complications including alimentary tract hemorrhage,vomiting,and abdominal distension decreased remarkably in EA group compared with conventional group (P ＜ 0.05).Conclusions EA stimulation at acupoints could promote the gastrointestinal peristalsis of neurosurgical severe coma patients and elevate the success rate of blind NJ tube placement,so it is beneficial for the implementation of early enteral nutrition (EEN).

Objective To explore the clinical characteristics, diagnosis and treatment of refractory hypertension caused by renal artery fibromuscular dysplasia (FMD) in children. Method The clinical data of a child with refractory hypertension caused by FMD were retrospectively analyzed. Results A boy, with onset at age of 4 years, had significantly increased blood pressure and decreased serum potassium. His renin and angiotensin levels were significantly elevated. The boy was diagnosed with renovascular hypertension by color Doppler ultrasonography, enhanced thoracoabdominal CT and vascular reconstruction. Oral administration of a variety of antihypertensive drugs is not effective. The child was finally diagnosed of refractory hypertension caused by FMD using renal angiography. The child was not suitable for surgery. After adjusting the antihypertensive drugs, the blood pressure of the child tended to be stable. The boy received continuous follow-up for 8 years. The antihypertensive regimen was adjusted annually and blood pressure fluctuations and target organ damage were dynamically assessed. Conclusion Children with FMD caused renal vascular hypertension may have no specific manifestations in the early stage. The drug treatment is preferred, and surgical treatment may be considered.

Wistar rats(n=24) were divided into normal control group(NC), food restriction group(FR), and catch-up group(RN). Serum glucose,lipids, gastrin, the ratio of visceral fat to body fat, adipocyte CCK2R mRNA and protein levels were determined. Compared with NC group, FR rats had lower serum gastrin and visceral fat formation. The adipocyte CCK2R mRNA and protein levels of FR rats were lower than those of NC rats. Serum gastrin level of RN rats was higher than those of FR and NC rats(P＜0.05). The ratio of visceral fat to body fat in RN rats increased compared with FR rats and was close to that of NC rats. The adipocyte CCK2R mRNA and protein levels of RN rats were higher than those of FR and NC rats. Gastrin and its receptor pathway possibly play a role in the mechanism of visceral fat accumulation in catch-up rats.

ObjectiveTo explore the bone anabolic effects after a single local injection of simvastatin into femoral cavities of osteoporotic rats.MethodsThirty-six female SD rats(3 months old,body weight 250-300 g) were ovariectomized(OVX) and low-calcium-diet fed for 3 months,OVX rats were randomized into 3 groups(n=12).Left femurs of group A,B and C were injected with 0,5 and 10 mg simvastatin,respectively.Half of the rats in each group were randomly euthanized separately 1 and 5 months after simvastatin injection.Left femurs were taken out for bone mineral density (BMD) assessment with dual energy X-ray absorptiometry,bone histomorphometic changes were analysized by Micro-CT,and two kinds of biomechanical tests were used to evaluate the osteogenic effects.ResultsOne and five months after injection,BMD in mid-diaphysis significantly increased in simvastatin-injected groups compared to the control group.For Micro-CT analysis,significant increase in total bone volume/total tissue volume,cortical wall thickness,trabecular thickness,trabecular number,and a significant decrease in trabecular spacing were observed in simvastatin-injected groups compared to the control group.For both biomechanics (the three-pointbreaking test of condyles and axial compressive testing of proximal femur),the values were significantly higher in simvastatin-injected groups than the control group.ConclusionLocal simvastatin treatment showed a positive effect on improving mechanical strength,structure of osteopenic femurs and BMD.Our findings may provide a new strategy for the prevention and treatment of osteoporosis,especially for osteoporotic fractures.

Cultured primary human umbilical vein endothelial cells (HUVECs) were divided into 4 groups:normal control( NG ),persistent high glucose ( HG ),hyperglycemia group ( TG ),and mannitol control ( MA )groups.After 1,4,and 7 days of culture,cells were collected.Cell proliferation,cell apoptosis,ROS,SOD,MDA,and NO level,eNOS mRNA and protein level were measured.Endothelial cell proliferation was inhibited in HG,TG,and MA groups compared with NG group.Hyperglycemia memory induced apoptosis of endothelial cells,increased ROS and MDA generation,and down-regulated intracellular SOD level,findings similar to those in HG group.After 24 h of culturing,eNOS expression and NO generation in both HG and TG groups were higher than those in NG group.However,after 7 days of culturing,eNOS expression and NO generation in both HG and TG groups were lower than those in NG group.These results suggest that in hyperglycemia memory cell model,transient hyperglysemia may lead to persistent imbalance in oxidative stress and reduce endothelium-derived relaxing factor NO level,indicating that hyperglycemia memory may play an important role in persistent vascular endothelial cell injury.
