In order to investigate the possibility that oxytocin (OT) is involved in stress reaction, the effect of OT or antioxytocin serum (AOTS) on rat swimming maintaining time was observed. On intraventrncularly administrating 0.625, 1.25, 2.5 and 5.0ng OT 5min before swimming,the swimming maintaining time was 29.32?5.84%, 44.92?4.54%. 60.18?4.21% and 80.48?3.62% shorter than that before injection,respectively.All the swimming maintaining time of the experimental groups was shorter significantly than that of the control group which was intraventricularly injected saline (p

Objective To observe the changes and relationships of glucose (Glu),insulin(Ins) ,insulin-like growth factor-1 (IGF-1) in newborn infant with hypixic-ischemic encephalopathy (HIE) and the protective role which Ins,IGF-1 worked on neuron.Methods HIE 50 cases,the quantity of IGF-1 in serum was detected by radioimmunoassay,the quantity of Ins in serum was detected by chemiluminescent immunoassay,the quantity of glucose in serum was detected by the instrument with type of Rokangquan TM accutive.The umbilical vein blood 2 mL were drawn from 20 cases of controls after birth.The indexes were detected by the same methods.Results 1.In acute period,the level of serum IGF-1 reduced obviously in newborn infants with HIE,and Glu increased obviously.There was a negative correlation between IGF-1 and Glu.The changes related with neonate complications.In rehabilited pe riod,the Glu get to normal,the IGF-1 was a little higher than that in acute period.but it still was lower than that of control group.There was negative correlation between IGF-1 and Glu.2.The level of Ins in serum of newborn infants with HIE had no obvious changes compairing with control group in acute period and rehabilited period.It had no relations with Glu,Ins.Conclusions It approves that IGF-1 and Glu in serum of newborn infants with HIE have obviously changed.This result will provide an academic base on treatment of HIE.

Objective To investigate the CT imaging features of pancreatic fatty replacement and its clinical significance. Methods Three patients with pancreatic fatty replacement detected by CT were retrospectively analyzed. CT examination included plain scan and contrast-enhanced scanning at the arterial and portal venous phases. The shape, size, density, pancreatic lobulation and interlobular spaces, course of the pancreatic duct were carefully observed. The clinic and laboratory data were also analyzed to determine the clinical significance of pancreatic fatty replacement. Results ①Imaging features: Two patients had complete fatty replacement involving the entire pancreas, another one had most fatty replacement sparing the posterior aspect of head and tail. Two patients had regular configuration of pancreas. The size of pancreas was slightly enlarged in 2 patients. Lobular atrophy and widening of interlobular spaces were present in all 3 patients. The pancreatic duct was normal in 3 patients. ②Clinic findings: Chronic diarrhea was present in 3 patients. Two patiens had diabetes (one had chronic cholangitis with choledochal lithiasis), another one had small stone in the common bile duct. Serum lipase was low in 3 patients, of which one had low serum amylase. Conclusion Pancreatic fatty replacement demonstrates certain characteristic CT appearances, and is usually associated with disturbances of both the endocrine and exocrine functions of the pancreas.

Epicatechin content in Uncaria macrophylla Wall. was determined by RP-HPLC. As aresult, the epicatechin contents were 0.38％ in the hook and stem, and 0. 820％ in the leaf. Thus it seemedto be more worthwhile to produce epicatechin from the leaf rather than from the hook and stem.

Methods including stimulation, cauterization, of nuclei and measurement of pain threshold were used to clarify the role of paraventricular nucleus of hypothalamus (PVH) in pain regulation. Results showed that electrical or L-glutamate sodium stimulation of PVH could elevate the pain threshold in the rat dose-dependently, electrical cauterization of PVH could reduce the pain threshold; and removal of the pituitary gland could not influence the effect of L-glutamate sodium on pain threshold. These results suggest that PVH may play an important role in pain regulation.

Objective:To investigate the relationship of hypertension with osteoporosis(OP)and bone mineral density(BMD) in elderly type 2 diabetic women.Methods: A total of 179 elderly type 2 diabetic women were categorized into hypertension group(n=124)and non-hypertension group(n=55).Lumbar and hip BMD were measured by dual-energy X-ray absorptiometry.Prevalences of osteoporosis were compared between the two groups using Chi-square test,and BMD was compared using covariance analysis.The correlation between the osteoporosis and risk factors was analyzed using binary logistic regression method.Results: The prevalences of osteoporosis(total OP,lumber OP and hip OP) in non-hypertension group were higher than that of the hypertension group(Pt=0.037,Pl=0.042 and Ph=0.051,respectively).Lumbar and hip BMD in the hypertension group was higher than that in the non-hypertension group,and there were significant differences in L3 and L4 BMDs between the two groups(P3=0.040,P4=0.021);however,the difference disappeared after adjustment for body mass index(BMD).After adjustment for C peptide,the P value also increased,but not as obvious as after adjustment for BMI.Binary logistic regression analysis showed that OP was associated with age,BMI and osteocalcin,but not with hypertension.Conclusion: OP is associated with the age,BMI,and osteocalcin,but not with hypertension in elderly type 2 diabetic women.

Objective To discuss the relation between level of Hs-CRP and glycometabolic disturbance in patients with acute coronary syndrom. Methods 155 patients with acute coronary syndrome were divided into 3 groups according to the WHO standard of diabetes diagnosis,normal glucose tolerance group(group A,44 cases),impaired glucose tolerance group(group B,60 cases),diabetes group(group C,51 cases). All cases were checked by the 75g glucose tolerance test, blood Glucose, insulin, HbA1c,lipid,hypersensitive C reaction protein(hs-CRP). 95 patients were checked by coronary angiography(CAG). Statistic comparison were measured among three groups including the levels of hs-CRP,insulin,HbA1c,lipid and coronary artery lesions. Results The levels of Hs-CRP,PBG, FINS, PINS,HbA1c,TC,LDL-C in both group B and C were higher than those in group A;The levels of TG,PINS were not found significant differences between group B and C. The level of Hs-CRP was correlated with the levels of PBG,PINS,HbA1c,TC,LDL-C. The coronary artery lesions showed by CAG in group B and C were more severe than those in group A,coronary multivessel changes in group B and C were more frequent than in group A,it had no significant difference between group B and C.Conclusion Compared with the patients of normal glucose tolerance, patients with glycometabolic disturbance have higher levels of hs-CRP,their coronary artery lesions are more severe.

AIM:To observe the image features of Vogt-Koyanagi-Harada disease (VKH) and multiple central serous chorioretinopathy (CSC) by fundus fluorescein angiography (FFA) and optical coherence tomography (OCT).METHODS:Thirty-two eyes of 17 patients with VKH and thirty-five eyes of 30 patients with multiple CSC were collected from 2009 to 2016 in my hospital.RESULTS:All the eyes with VKH were found small and dense fluorescein leakage in the early stage.The 17 eyes (53%) with VKH were found fluorescein accumulation in the final stage;24 eyes (75%) with VKH were found high fluorescence of optic disc.All of eyes with multiple CSC were found multifocal leakage in the early stage.And 2 eyes (6%) with multiple CSC were found high fluorescence of optic disc.There were 28 eyes (14 patients) with VKH and 25 eyes (22 patients) with multiple CSC had been done OCT in my hospital.Retinal pigment epithelial fold was only found in VKH.Fluctuation of internal limiting membrane (ILM) and membrane structure had higher sensitivity to diagnostic VKH from to multiple CSC, with sensitivity of 54% and 68% respectively.CONCLUSION:There are some similarities as well as differences between FFA and OCT in diagnosis of VKH and multiple CSC.A combination usage of FFA and OCT can be more effective in distinguishing VKH from multiple CSC.

Objective To evaluate catheter thrombectomy,mechanical thromboaspiration and catheter-directed thrombolysis for the treatment of deep venous thrombosis.Methods From January 2015 to February 2016,60 patients with acute deep vein thrombosis were placed the inferior vena cava filter from contralateral femoral vein or right internal jugular vein.A 5 F pigtail catheter was led to the ipsilateral deep vein,bolus urokinase was given and catheter thrombectomy was undertaken and thromboaspiration was carried out using 10-12 F catheter,then through catheter continuous infusion of urokinase.Results 45 cases were cured,8 cases were significantly improved,5 cases were improved,2 cases were judged as ineffective,the effective rate was 96.6％.Before thrombolysis the thigh circumference difference between affected limb and the contralateral limb was (3.6 ± 1.9)cm (P ＜0.05),calf circumference difference was (4.6 ±2.1)cm (P ＜ 0.05);The difference between the affected limb and contralateral thigh circumferences was (0.19±0.90) cm (P ＞ 0.05),calf circumference difference was (0.5 ± 1.0) cm (P ＞ 0.05).Conclusions Catheter thrombectomy,thromboaspiration and catheter-directed thrombolysis for deep venous thrombosis is safe and effective.
