Objective:To study the characters of perioral muscle p re ssure of the adult patients with skeletal crossbite. Methods:20 patients were diagnosed to be with skeletal crossbite. The perioral muscle press ures on upper and lower central incisors, first molars and cuspids were measured buccally and lingually at rest position. 10 health adults were served as the co ntrols. Results:The perioral force in skeletal crossbite group was larger than that in the control group on the correspondence area(P0.05). In the skeletal cross bite group, the perioral force on the mandibular area was larger than that on th e correspondence maxillary area(P0.05). The muscle pressure on the labial side was larger than that on t he lingual correspondence side in both groups(P

Objective To observe the effects of Chinese herbal meridian and vessel deoppilant compound on the dysfunction of endothelium-dependent dilation (EDD) of simple obesity patients, and explore its mechanism. Methods Sixty-five obese patients with dysfunction of EDD (denoted by FMD: flow mediated brachial artery vasodilatation rate) were found through the prehminary high-resolution vascular ultrasound check, and randomized into the therapy group (treated with Chinese herbal meridian and vessel deoppilant compound) and the control group. The therapy group took Xinxiang Shuluo 2# capsules three times a day, 3 gram each time, and the control group was given the same doses of starch capsules. The experiment lasted 12 weeks. Before and after the experiment, FMD and inner diameter of brachial arteries (DO) of all the patients were measured, and the changes of total cholesterol (TC) and trigiyceride (TG) in serum were compared. Results FMD of the therapy group was significantly higher than the control group (P

Objective To investigate the localization and mRNA expression of dopamine receptor subtype D_4 and D_5 mRNA in human stomach and duodenum by in situ hybridization. Methods The oligonucleotide probe was synthesized and labeled with digoxin, and then hybridized with human gastric and duodenal samples, which were stored in liquid nitrogen, fixed in hypothermia, and embedded in paraffin. The results were recorded and quantitatively analyzed using the pathological image computer analysis system. Results Dopamine receptor subtype D_4 and D_5 mRNA both expressed in human stomach as well as duodenum. They distributed mainly in the interstitial of mucosal glands and the lamina propria near lamina muscularis mucosa. The mRNA expression value of D_4 was higher than that of D_5 in both stomach and duodenum. In stomach, the number of positive target cells was 41.29?5.06 vs. 26.25?5.82 ( P

Objective To investigate the mechanism of Chinese herbal medicine compound (Kaiyuqingwei Decoction) improving islet cells function of type 2 diabetes. Methods The models of type 2 diabetic rats were established by feeding with high-fat-diet and injecting low dosage of streptozotocin (15 mg/kg BW). Rats were randomly divided into model group, Kaiyuqingwei group, and Rosiglitazone group and normal control was established, at the same time, fasting and post-glucose loading 2 hours blood glucose, serum fructosamine and basal insulin were determined. Euglycemic hyperinsulin clamp technique was adopted to evaluate insulin sensitivity of periphery tissues, and intravenous glucose tolerance test to evaluate islets function. Adopting immunohistochemistry stain (EnVision) and computer image analysis technique to determine the expression of insulin, insulin receptor and insulin receptor substrate-1 in islets. Results There were insulin resistance, dysfunction of islet cells and obvious increase of blood glusose in model rats. All these could be improved by Kaiyuqingwei Decoction and Rosiglitazone. Meanwhile, immunohistochemistry stain of islets demonstrated that Kaiyuqingwei Decoction could increase expression of IRc and IRS-1. Conclusion Kaiyuqingwei Decoction have a certain positive role in improving glucose metabolism of type 2 diabetic rats. The mechanism include two aspects, one is elevation of insulin sensitivity, another is amelioration of dysfunction of islet cells. One of the important mechanisms of amelioration of dysfunction in islet cells is amelioration of insulin signal transduction in pancreatic islets.

Objective To explore whether there is any abnormality in the tongue position of the open bite. Methods Tongue position was defined as the relative position of its body in the oral proper cavity on profile cephalometric roentgenogram which was enhanced by the iodine oil applied to the tongue surface. The tongue position was compared between open bite group and normal bite group with student's t test to determine the variation of open bite. Results Compared to the normal bite group, the root of tongue was closer to the uvula in the open bite group, and the distance between the dorsum of tongue and the surface of palate was decreased as well as the tip of tongue was nearer to the incisors. Conclusion The open bite's tongue position is characterized by more upward and more forward and this position may be one of the causes of open bite.
