Objective To compare the effects of single and complex emotional stimuli on animal model of liver depression syndrome,in order to find out an animal model of liver depression syndrome with more similar clinical manifestations.Methods Based on the previous screening work,different methods,i.e.tail clamping,limb binding,putting a cangue on the neck,were used respectively,or using the three methods in combination to establish rat models of liver depression syndrome.A comparison table of human and rat liver depression syndrome was prepared,a mark sheet of evaluation criteria was made,general condition was observed and body weight was measured,and positive response to drugs and changes of hormonal levels were evaluated to identify whether the models were established successfully.Results Rats in the control group grew well and showed no abnormalities.There were lots of abnormal phenomena in the model group especially in the complex emotional stimulus modeling group.They were maniac with acute stress or depressive with chronic stress,had dry hair,small and less feces,many of the rats had hair loss,red eyes and shortness of breath symptom.They showed a significantly lower body weight gain and higher levels of CRH in hypothalamus and plasma ACTH and CORT.The manifestations were much more severe in the complex-emotional stimuli-induced model group than that in the single-stimulus prepared model groups.The drug-treated group showed considerable alleviation of the symptoms and improvement of the parameters closing to normal levels.Conclutions Establishing the rat model of stagnation of liver depression syndrome by complex emotional stimuli modeling method has good stability,with a short preparation period and high success rate,and presenting a better consistence with clinical liver stagnation of depression syndrome,so as to provide a suitable tool for TCM research.

Objective To explore the clinical features of diabetic macular edema (DME) with optical coherence tomography (OCT) and correlation with visual function. Methods Forty-nine eyes from 40 patients with DME (DME group) and 31 eyes from 31 patients without DME (control group) were examined with OCT,pattern reversal visual evoked potentials (P-VEP),macular perimetry. According to proliferative diabetic retinopathy (PDR), 49 eyes with DME were divided into group A (without PDR, 30eyes) and group B (with PDR, 19 eyes). Results The retinal macular thickness of central fovea in DME group [(299.25±63.87)μm] was more than that in contol group [(204.35 ± 37.94)μm], visual acuity and macular visual field in DME group were significantly different than those in control group, respectively (P ＜ 0.05). The retinal macular thickness of central fovea,visual acuity and visual field were no significant differences between group A and group B (P＞0.05). OCT macular thickness and visual correlation coefficient was -0.437(P＜ 0.05 ); OCT macular thickness and mean defect correlation coefficient was 0.441(P ＜ 0.05). Conclusions OCT can provide a useful tool for monitoring the occurrence and development of DME, can assess the response to treatment. With increasing of the macular retinal thickness, the visual acuity and macular visual field of visual function are more damaged.

One strain of Pseudoalteromonas sp. E18 was isolated from the sea mud of Ningbo, Zhejiang. It can produce indigo pigment. The morphological, cultural and biochemical characteristics of the bacterium were studied. The indigo pigment was also extracted. The results showed that the maximum absorption peak of the pigment was at 579nm. The pigment was stable to UV, Na_2SO_3,It was also stable at pH 3～9. The pigment was unstable to the sunlight and high concentration H_2O_2. Temperature of 60℃～80℃ could increase the hue while temperature higher than 90℃ could reduce the hue.

Objective To investigate the effects of adiponectin on the development of atherosclerosis.Methods The in vivo role of adiponectin on the development of atherosclerosis in rabbits was investigated mainly using adiponectin-producing adenovirus(Ad-APN)and intravascular ultrasound(IVUS).On day 14 after Ad-APN local transfer to the intima of abdominal aortas,abdominal IVUS images were recorded and then rabbits were sacrificed.Abdominal aortas were collected and performed histochemical analysis.Results Ultrasonography revealed a significantly reduced atherosclerotic area,in abdominal aortas of rabbits infected through intima with Ad-APN,by 36.39% compared with the area in adenovirus expressing β galactosidase gene(Ad-βgal)treated rabbits(P＜0.01),and by 37.50% compared with that before treatment(P＜0.01).The lumen area stenosis was also reduced by 23.37%(P＜0.05)and 33.15%(P＜0.01),respectively.In rabbits with Ad-APN infection,the atherosclerotic plaque area as seen on Oil Red O staining was reduced significantly,by 30.70%(P＜0.05)and the greatest thickness of plaque was reduced,by 20.83%(P＜0.05)as compared with those in Ad-βgal-treated rabbits,respectively.Conclusions Intravascular ultrasound analysis is a valuable method in the in vivo study about the effects of adiponectin on the development of atherosclerosis.

Objective To investigate the clinical value and the feasibility of strain-blood pressure index(SBPI) in assessing the elasticity of brachial artery and anterior tibial artery in patients with type 2 diabetes mellitus. Methods Forty-six type 2 diabetic patients and 50 healthy volunteers were involved. Maxmum of circumferential strain (CSmax) of brachial artery and anterior tibial artery were acquired through strain and strain rate imaging(Xstrain). Local systolic blood pressure(LSBP) and local diastolic blood pressure(LDBP) of brachial artery and anterior tibial artery were measured at the same time. SBPI,tibial-brachial index (TBI), and ankle-brachial index(ABI) were calculated, SBPI = CSmax/[(LSBP-LDBP) /LDBP]×100%,TBI = SBPI of anterior tibial artery/SBPI of brachial artery, ABI = LSBP of anterior tibial artery/LSBP of brachial artery. Parameters were compared between the case group and the control group. Results SBPI of anterior tibial artery and TBI had significant difference between the case group and the control group( P < 0.05), while SBPI of brachial and ABI had no significant difference( P >0. 05).Conclusions SBPI might be a new index for evaluating the elasticity of medium-sized arteries in patients with type 2 diabetes, and different changes caused by type 2 diabetes between brachial artery and anterior tibial artery could be reflected by TBI.

Objective To investigate whether there is amyloid fibers in the mature neutrophils and to reveal the molecular mechanism of the formation of AD amyloidosis. Method Thirty cases of AD patients and 30 healthy control were enrolled. The white blood cell, the red blood cell,hemoglobin and neutrophil absolute value were determined by Sysmex X5-500i hematology analyzer. The neutrophils and amyloid variable specific probe affinity were measured, The starch like variable fluorescence intensity in plasma was dtected by the sulfur T (Thioflavin T, ThT) method. Results The affinity test results showed that the amyloidosis fluorescent probe (ThT) can be combined with tissue amyloid fibers specifically. The neutrophil amyloid fibers staining also showed a positive reaction. Compared with the AD group, no significant differences were found in white blood cell, red blood cell, hemoglobin and neutrophil absolute value level in the healthy control group The serum amyloid variable fluorescence intensity in the AD group was significantly higher than that in the control group (P < 0.05). Conclusion The amyloid fibers was found in the mature neutrophils, and the level of plasma amyloid fibers was significantly increased in the AD patients.

And specific nursing mode, which was different from in-hospital, was performed in perioperative period. Results All the animal modes of closed hepatic trauma and hemorrhage were rescued successfully, and no operative complications were found. Conclusions With the cooperation of specific nursing mode, the emergency angio-interventional embolic treatment of closed hepatic trauma and hemorrhage in field minimally-invasive interventional shelter under the complex outdoor environment is feasible.

Aim To establish phlegm and blood stasis, qi-stag-nation and blood stasis, phlegm turbid+qi-stagnation and blood stasis model in rats and to study the characteristics of animal models with different blood stasis. Methods SD rats were ran-domly divided into normal group, high fat diet group, chronic unpredictable mild stress group ( CUMS ) and high fat diet +chronic unpredictable mild stress group. Different states of blood stasis rat models were established by corresponding factors for 6 weeks. Indexes of weight, open field behavior, serum lipids and corticosterone were monitored dynamically at the 2 nd, 4 th, 6 th weeks. At the end of the experiment(6th week), the heart func-tion was detected by small animal ultrasound and the left ventric-ular intubation. The blood rheology indexes were detected by the viscosity tester and red blood cell deformation/aggregation test instrument. Results Compared with the normal group, blood stasis could be induced by high fat diet and chronic unpredicta-ble mild stress, introducing the influence of different degree on animal behavior, blood lipids, heart function and blood viscosi-ty. When the two factors were superimposed, the changes of the indexes about blood stasis were the most significant. Perform-ance as: compared with normal control group, a significant re-duction was observed in body weight ( P < 0. 01 ); horizontal movement, vertical movement and movement time were reduced (P<0. 01 or P<0. 05) at the 2 nd week;at the 2 nd and 4 th week, serum corticosterone was increased ( P <0. 01 or P <0. 05) as well as TG at the 4 th and 6 th week (P<0. 01); at the 6 th week, velocity of blood was slowed down ( P<0. 01 );left ventricular anterior wall and posterior wall thickness at end-systolic was increased ( P<0. 01 or P<0. 05 ); left ventricular diastolic index was increased ( P<0. 01 ); the maximum rate of myocardial contraction was decreased ( P < 0. 05 ); the whole blood viscosity was increased ( P<0. 01 ) . Conclusions Blood stasis could be formed by high fat diet and chronic unpredictable mild stress, which has different characteristics. When the two factors are superimposed, the abnormal behavior, blood viscosi-ty, heart function, blood lipid and other indexes of the animal could obviously appear, which can provide the basis for the stud-y of blood stasis syndrome and related drugs.
