Diabetic cardiovascular autonomic neuropathy is the most common and troublesome complication of diabetes mellitus.Diabetic cardiovascular autonomic neuropathy contributes greatly to the morbidity,mortality.Factors in the pathogenesis of these complications are altered metabolism,vascular insufficiency,loss of growth factor trophism,and autoimmune destruction of nerves in a visceral and cutaneous distribution.There are studies in progress that suggest cardiovascular autonomic nerves can be induced to regenerate,and the future for patients with diabetic cardiovascular autonomic neuropathy is brighter.

Objectives To explore the clinical effect of external fixator combined antibiotic-calcium sulfate packing medullary cavity, VSD continuous drain with negative pressure and local skin flap transposition for the treatment of postoperative infected nonunion after initial debridement. Methods 20 cases of traumatic osteomyelitis from August 2012 to August 2014 were selected and taken antibiotic-calcium sulfate to focal zone. The patients were taken first-stage bone grafting for small bone defects and osteotomy for lengthening for big bone defects. For patients with cutaneous injury, local skin flap transposition was taken. For other patients with partial flap necrosis and non healing wounds, VSD continuous drain with negative pressure was taken. Results Operative incisions of 12 cases were primary healing, two cases were healing by second intention, four cases of flap were survived after local skin flap transposition, and two cases of flap were partial necrosis and healed by second intention. 11 cases of immobilization with external fixator, bone healing was satisfactory in seven cases after osteotomy for lengthening and two cases of bone delayed union in osteotomy for lengthening and recovered after bone transplantation. All patients were followed up for average 19(6-32) months with permatoplasty survived; all the infection of wounds was controlled and relapse-free. The fracture healing period was eight(4-12) month without pin site infection, osteoporosis and deformed healing. But there were 1 cases of knee stiffness and two cases stiffness of ankle joint. Conclusion After initial debridement, taken external fixator and taken antibiotic-calcium sulfate to medullary cavity and fracture ends. The patients were taken first-stage bone grafting for small bone defects and osteotomy for lengthening for big bone defects. For the skin defect after local flap grafting, taken VSD continuous drain with negative pressure for partial necrosis of flap occurred and non healing wounds cases. The method obtained prominent curative effect, reduces the treatment cycle and reduce the complications in the treatment of postoperative infected nonunion.

Objective To determine the value of 18F-FDG PET-CT in detecting the primary origin of cancer of unknown primary (CUP).Methods A total of 48 patients (age range 41-82 years,mean age of 57±16 years, 20 females) were retrospectively selected. All patients were diagnosed as CUP and were examined by 18F-FDG PET-CT scan.The patients were divided into cervical lymph node metastasis group (28 cases) and extra-cervical lymph node metastasis group (20 cases) according to different metastasis site.Sensitivity of 18F-FDG PET-CT to detect primary tumor site was compared between these two groups.Results 18F-FDG PET-CT detected primary tumors in 32 of 48 patients (66.7 ％), the cervical lymph node metastasis tumors in 22 of 28 patients (78.6 ％), and extra-cervical lymph node metastasis tumors in 10 of 20 patients (50.0 ％).There was significant difference between cervical lymph node metastasis group and extra-cervical lymph node metastasis group (x2 =4.286,P ＜ 0.05).Conclusion 18F-FDG PET-CT has a high sensitivity to detect primary origin of CUP,especially for patients with cervical lymph node metastasis.

Forty rats were randomly divided into four groups and intraperitoneal injection of 1%lidocaine 400mg/kg (group Ⅰ)、1%lidocaine-?-cyclodextrin 400mg/kg (group Ⅱ)、1%alkalinized lidocaine 400mg/kg(group Ⅰ)and 1% alkalinized lidocaine-?-cyclodextrin 400mg/kg(group Ⅳ) respectively. The results showed that there was a significant difference of lethal time between group Ⅰ and Ⅱ, and no significant difference between gronp Ⅲ and Ⅳ; the times of toxic and lethal effects of group Ⅲ and Ⅳ were shortened markedly as compared to group Ⅰ and Ⅱ. It is concluded that ?-cyclodextrin can postpone the release and absorbance of lidocaine,and alkalizer can weaken this action of ?—cyclodextrin.

Objective In order to analyse the problem that eligible water from factory will deteriorate during the transportation in the water supply networks. The aim of the present paper is to provide theoretic basis to ameliorate the water quality and make drinking water more secure. Methods Regarding water supply networks as a grey system, applying grey relational analysis to establish the attribution recognition model. The classification of water quality was treated as a grey sort and the state of water quality was a grey system. Water quality classified rank was determined and the water quality was analyzed according to the grey relation analysis theory. Results Three monitoring spots in north networks which included fourteen water quality gene was calculated. The relation degree matrix was educed. The result showed that the water quality of the first and the third monitoring spots belonged to grade one, and the second spot belonged to grade two. Conclusion Applying attribute recognition model based on the grey relation to analyze the water quality in the water supply networks, the case study shows that the grey relational analysis method is more reasonable, simple, reliable and informative. The effect of subjective factors is eliminated. The accuracy of model is verified by the experimental data in the end. There is a good agreement between the calculated result and actual condition.

Objective: To observe the therapeutical effects of Lipo PGE_ 1 in the treatment of diabetic peripheral neuropathy. Methods: 42 cases of type 2 diabetes patients with diabetic peripheral neuropathy were recruited and were divided into two groups at random:therapy group treated with Lipo PGE_ l and control group treated with Vitamine B_ 1 and Vitamine B_ l2 . Results: After a treatment of 20 days,symptoms such as pain,numbness and hypoesthesia in cases of therapy group had been improved at different degrees.Examination of Neuroelectrophysiology indicated an increase of sensory nerves conduction velocity and motor nerve conduction velocity.The effects of therapy group outweighed that of control group. Conclusion: Lipo PGE_ 1 can significantly relief the symptoms of diabetic peripheral neuropathy and increase nerve conduction velocity.The mechanism of action may involve improvement of blood-supply of nerve by vasodilatation and inhibition of platelet aggregation that caused by PGE_ l .

Objective To explore the effect of valproate(VPA) on body mass index(BMI),leptin and serum lipids in children with epilepsy.Methods (Twenty-)four cases with epilepsy were selected.BMI and serum levels of leptin,total cholesterol(TC),(triacylgly)-cerol(TG),high density lipoprotein-cholesterin(HDL-C),low density hipoprotein-cholesterin(LDL-C) after treated with VPA for 3 months and 6 months were determined.Results The levels of BMI,leptin,TC,TG,LDL-C after treated 3 months were all significantly higher than those of initial(all P0.05).Those in treated 6 months were same as levels of treated 3 months.Only LDL-C level was lower than that of 3 months and same as level of before treatment.Conclusion VPA do have efficacy to cause obesity in children with epilepsy,and most of the cases occur in the first 3 months after VPA treatment.

Objective To investigate the expression of NF-?B and its significance to sciatic nerve in diabetic rats.Methods The model of diabetes was induced by streptozotocin.The sciatic nerve conduction velocity(NCV)and NF-?B activity were observed at 1 month(DM1),3 months(DM3)and 6 months(DM6)during the experiment respectively.Results Compared with normal control group,NCV was significantly slower in DM3 and DM6 groups.There was no difference in NCV between normal control group and DM1 group.The expression of NF-?B,by electrophoretic mobility shift assay(EMSA),was markedly higher in DM groups(P

Objective:To study the express levels of transcription factor nuclear factor-?B in diabetic rat retina. Methods: Sprague-Dawley rats were randomly divided into control groups of 1, 3 and 6 months, diabetic groupsof 1, 3 and 6 months, respectively. Diabetic model of rat was induced by injecting streptozotocin (STZ). The retinal morphology was observed in paraffin slide by microscope. The expression of NF-?B was detected by immunohistochemistry and electrophoretic mobility shift assay. Results: Histopathological changes were detected at 3 and 6 months. The changes were severer at 3 months than at 6 months. Activation of retinal NF-?B was detected by electrophoretic mobility shift assay and immunohistochemistry at 1 month, and the NF-?B remained activated at 3 and 6 months in diabetic rats. Conclusion: NF-?B is activated in retina in diabetes before histopathological changes can be seen, and remains activated for the duration when the retinopathy is developing.
