Pre-disease is a condition in which characteristic symptoms are not prominent.That is to say pre-disease is lack of key proof to be diagnosed as a disease,but has common symptoms as well as signs.It is said in Inner Canon of Huangdi that "prefer prevention to treatment",which needs doctors to find unusual symptoms in early stage of diseases then take positive preventive measures to help patients regain health.Diabetes mellitus(DM) is one of the life style-related diseases which associated with unhealthy habits of human beings.Pre-diabetes mellitus mainly refers to impaired glucose tolerance(IGT).With the help of modern medical technology,doctors and patients should focus on pre-diabetes by combining TCM treatment based on syndrome differentiation and health care,in order to stop DM at early stage.

Objective To observe the efficacy of Qingre Jiangzhuo prescription in the treatment of overweight subjects of type 2 diabetes mellitus. Methods Two hundred and four cases were divided into 2 groups in a randomized, paralleled, contrast, prospective study. The control group was treated with metformin tablet and the trial group was treated with Qingre Jiangzhuo prescription. The efficacy and safety of the two groups were compared on HbAlc, FBG, P2BG, TC, TG, BMI and AE after 12 weeks. Results After treatment, all indexes of the trial group were markedly improved compared with before treatment (P 0.05). The rate of AE in the trial group was less than that in the control group. Conclusion Qingre Jiangzhuo prescription has curative effect on type 2 diabetes mellitus patients with better safety.

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 study the effects of nicotine on GDNF and dopamine content in striatum of Parkinson's disease (PD) rats.Methods 6-OHDA was stereoscopically injected to right side of the mesencephic ventral tegmental area (VTA) and substantia nigra pars compacta (SNpc). Nicotine of different dosages was intraperitoneally injected into PD rats.With biochemical,immunohistochemical techniques, we observed the changes of GDNF expression and dopamine content in striatum.Results Nicotine was intraperitoneally injected into PD rat models before or after the operation,striatum GDNF expression and DA content had significant improvement as compared with PD group (P

Objective To study the protective and therapeutic effect of Luotong on the retinal microvessel kinetic morphological changes during various stages of streptozotocin-induced diabetic rats. Methods The diabetic rat model was setup by a single intraperitoneal injection 65 mg/kg of streptozotocin. Diabetic model rats were randomly divided into diabetic model group (6, 9, 12 months subgroups), diabetic group protected with Luotong (6 months) from the onset of diabetic model (LT group)and diabetic group treated with Luotong (3, 6 months subgroups ) 6 months after the onset of diabetic model (LT1, 2 group). The eyeballs were removed at 6, 9 and 12 months, respectively. The whole mounts of retinal digestion were prepared and stained with PAS staining method. The light microscope and transmission electron microscope morphological observations were performed and the basilar membrane thickness of retinal capillaries were quantitatively analysed by LEICA-Q550IW computer image system. Results At 6 months, the retinal microvessel morphological changes of LT group were less severe than those of 6 month model group. At 9 months of the diabetic model rat, the retinal microvessel morphological changes were prominent. 3 months after Luotong therapy, the retinal microvessel changes were partly improved in comparison with 9 month model group but still aggravated gradually. At 12 months, the retinal microvessel morphological changes of diabetic model rats were very severe. 6 months after Luotong therapy, the retinal microvessel changes were significant mitigated compared with 12 month model group. The results of computer image analysis indicated the retinal capillary basilar membrane thickness in diabetic group protected or treated with Luotong were significant decreased in comparison with homeochronous model group (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 the imaging features of solitary fibrous tumor (SFT)in the head and neck.Methods The CT and MR findings of 10 patients with SFT in the head and neck confirmed by hsitopathology were analyzed retrospectively.All patients underwent CT (including contrast-enhanced dual-phase CT),and MR imaging was obtained in 2 patients.Results All 10 lesions were found as solitary masses ranging in maximum diameter from 20 to 1 1 5 mm (average 35.5 mm),with the location in the orbit (2 cases),nasal cavity and nasal sinuses (4 cases),parotid gland (1 case),supraclavicular region (1 case),subcutaneous tissue of the maxillofacial (1 case)and occipital region (1 case).The lesions showed elliptic shape in 7 cases and lobulated configuration in 3 cases.The majority (8/10 )of lesions demonstrated well-defined margin.The lesions on CT imaging were isodensity or low density, homogeneous density in 4 cases and inhomogeneous density in 6 cases,cystic changes in 2 cases,calcification in 1 case.9 lesions showed strongly homogeneous (n=3)or inhomogeneous (n=6)enhancement,1 lesion showed mildly homogeneous enhancement on contrast-enhanced CT imaging.On dual-phase enhanced CT,8 patients exhibited a rapidly enhancing and slow washout pattern,1 patient exhibited a rapidly enhancing and rapid washout pattern,and 1 patient exhibited delayed enhancement.The lesions showed homogeneous isointense relative to gray matter on T1 WI in 1 patient,mixed isointense and hypointense in 1 patient.On T2 WI,the lesion showed isointense signal in 1 patient,and heterogeneous mixed isointense and hyperintense signal in another.2 lesions demonstrated markedly homogeneous and inhomogeneous enhancement respectively.Conclusion Solitary fibrous tumors shall be considered in cases of inhomogeneous hypervascular tumors in the head and neck.Compared with the gray matter,isointense or mildly hyperintense signal on T2 WI, marked enhancement on contrast-enhanced CT,and a rapidly enhancing and slow washout pattern on dual-phase enhanced CT may be valuable imaging features of SFT.
