Objective To investigate the association of insulin dose with clinical factors of type 2 diabetes. Methods We reviewed the data of 214 type 2 diabetic patients who received insulin regimens.We compared the insulin dose and period at the targeted blood glucose levels among 6 groups according to different type of oral hypoglycemic agents. Results There existed statistically significant correlations of the glucose-targeted insulin dose with course,FPG,BMI,combination therapy with oral hypoglycemic agent(P<0.1,test level P=0.1).Merely metformin failure group took less insulin than the group admitted due to combination therapy failure (P=0.016, 0.53(0.35~0.62)U/kg and 0.63(0.51~0.75)U/kg respectively).The longest targeted period existed in the later. Relationship between the targeted bedtime insulin NPH dose and FPG level can be demonstrated by equation Y=0.255X+7.8. Conclusions The targeted insulin dose is influenced by synthetic factors. Patients admitted due to combination oral hypoglycemic drug failure have the maximal targeted insulin dose and the longest titration period. The final bedtime insulinNPH dose can be predicted by FPG level.

Objective: To investigate the effect of rat hyperplasia suppressor gene-1(rHSG-1) on the proliferation of aortic vascular smooth muscle cells(VSMCs) from spontaneously hypertensive rats(SHR). Methods:VSMCs were transfected with an adenoviral vector expressing rHSG-1(Ad5rHSG-1). The effect of rHSG-1 on the proliferation of VSMCs was investigated by cell counting, MTT assay and 3H-thymidine incorporation. We also analyzed the cell-cycle using flow cytometry and detected the expression of p27 Kip1 and p21 Cip1 by Western Blot. Results:The proliferation of VSMCs infected with Ad5rHSG-1 was inhibited,a 40% reduction compared with the control group(P

OBJECTIVE To assess the prevalence and analyze the influence factors of laryngopharyngeal reflux disease(LPRD) in the Fuzhou region, in order to provide a theoretical basis for the development of prevention and control measures for LPRD. METHODS A questionnaire survey in residents in Fuzhou by a random cluster sampling was carried out. Individual information, reflux symptom index(RSI) of Belafsky and risk factors were included. Patients more than 13 scores of RSI were defined as LPRD. Data were statistically analyzed. RESULTS A total of 4100 residents were investigated, 4063 of them were available. The prevalence of LPRD was 5.00%. Often eating too much, often drinking strong tea, menolipsis, rhinitis, tonsillitis were closely related to LPRD. CONCLUSION The prevalence of LPRD in Fuzhou region were closely related to many factors.

Objective To determine the prevalence and clinical features of peripancreatic vascular abnormalities in patients with pancreatitis.Methods The clinical data of 102 pancreatitis patients between January 2013 to December 2014 in the General Hospital of Shenyang Military Command who underwent contrast enhanced CT or contrast enhanced MRI scans were retrospectively analyzed.The radiological features of peripancreatic vascular abnormalities in such patients were examined, and the clinical features of pancreatitis patients with or without peripancreatic vascular abnormalities were investigated.Results Peripancreatic vascular abnormalities were found in 18 patients(17.6%), and vascular abnormalities were relatively common in portal vessels.No significant differences were observed on the age at onset, gender ratio, smoking status, alcohol consumption and length of stay between patients with and without peripancreatic vascular abnormalities.Compared with those without peripancreatic vascular abnormalities, patients with peripancreatic vascular abnormalities had a significantly higher incidence of peripancreatic fluid collection, pancreatic pseudocyst and gastric varices, and the differences were statistically significant(all P<0.05).Conclusions Peripancreatic vascular abnormalities can be complicated with pancreatitis.Enhanced CT or enhanced MRI were valuable in the diagnosis.Pancreatic pseudocyst, peripancreatic fluid collection and gastric varices were more common in pancreatitis complicated with peripancreatic vascular abnormalities.

Objective To investigate the expression of apoptosis-related proteins in rat cerebral cortex following traumatic brain injuries(TBI)and discuss the role of oxygen free radical-mitochondria signal pathway in Edaravone treating TBI.Methods A total of 180 male adult Sprague-Dawley rats were randomly divided into TBI group,Edaravone treatment group and control group.Each group was divided into six subgroups at 1,3,6,24,48 and 72 hours after TBI.Edaravone treatment group was injected with Edaravone(10 mg/kg)and the other two groups injected with the same volume of 0.9%normal saline.The pathological change in the rat cortex following TBI was observed with HE staining.At different time points,the expressions of Cytc,Bcl-2 and Bax in rat cortex as well as cell apoptosis and MDA change were observed by means of immunohistechemistry,TUNEL and TAB.Results HE staining showed scattered degenerated and necrotic neurous in cerebral cortex six hours after neuron injury,which peaked at 24 hours.Compared with control group,intermediate product MDA of free radical was increased six hours after TBI and peaked at 48 hours in Edaravone treatment group,which was lower than TBI group especially at 24,48 and 72 hours(P<0.05).Compared with control group,the immunity reaction of Cytc positive cells inereased at six hours and peaked at 24 hours in TBI group,with statistical difference at 3,6,24,48 and 72 hours(P<0.05).Compared with TBI group,the immunity reaction of Cyte positive cells was decreased obviously at 24,48 and 72 hours in Edaravone treatment group.Hyperexcitability of Bcl-2 after TBI reached peak at 3 hours and decreased gradually.But the expression of Bax was increased gradually after TBI and peaked at 48 hours,when Bax/Bcl-2 reached peak too.Folowing TBI,TUNEL positive cells increased gradually and reached peak at 48 hours,with mainly type Ⅰ TUNEL cells before 24 hours and typeⅡTUNEL cells after 24 hours.Conclusions There exist necrosis and apoptosis of nerve cells in cortex after TBI,especially apoptosis.Oxygen free radical mitochondria is one of the signal transduction pathways of nerve cell apoptosis following TBI.Edaravone exerts certain therapeutic effect on TBI.

Objective To compare the diagnostic efficacy of the V/Q scan and CT pulmonary angiography (CTPA) for the detection of acute pulmonary embolism (PE) in elderly patients.Methods Fortyfour patients (age ≥60 years old) with suspected acute PE underwent V/Q scan and CTPA.The diagnosis of PE by V/Q scan was based on the criteria of prospective investigation of PE diagnosis (PIOPED) Ⅱ and the prospective investigative study of acute PE diagnosis (PISA-PED).The final diagnosis was made clinically.The sensitivities,specificities and accuracies of PIOPED Ⅱ,PISA-PED,CTPA and Wills score were calculated and compared using x2 and Fisher's exact tests.Kappa analysis was used to analyze the diagnostic accordance rate of PIOPED Ⅱ and PISA-PED.Results The sensitivities of PIOPED Ⅱ,PISA-PED and CTPA in the diagnosis of PE were 70.00% (14/20),84.62% (22/26) and 65.22% (15/23),respectively (x2 =0.069-1.545,all P>0.05).The sensitivity of Wills score was significantly lower (23.08%,3/13).The specificity of CTPA (93.75%,15/16) was significantly higher than those of PIOPED lⅡ and PISAPED (80.00%,12/15 and 61.11%,11/18,both P<0.05).The accuracies of PIOPED Ⅱ,PISA-PED and CTPA were 74.29% (26/35),75.00% (33/44) and 76.92% (30/39),respectively (x2 =0.005-0.070,all P>0.05).The accuracy of Wills score was significantly lower (52.17%,12/23).The diagnostic accordance rate of PIOPED Ⅱ and PISA-PED criteria was 77.14%(27/35),Kappa=0.547,P<0.05.Conclusion V/Q scan and CTPA have no significant difference for the diagnosis of PE in the elderly patients.
