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.

OBJECTIVETo explore clinical significance of rotational axis of distal femur on Chinese adults in total knee arthroplasty (TKA).

METHODSThere were 86 Chinese adults (106 normal knees) including 47 males (53 knees) and 39 females (53 knees), 54 knees were on left and 52 on right. The CT scan was employed in the distal femur. The scan direction was aligned to be on the plane perpendicular to the mechanical axis of the femoral. The CT images of cross sections across lateral and medial femoral epicondyle were moved to personal computer,lateral angle between anterior posterior line (APL) and surgical transepicondylar axis (STEA) (ATA),lateral angle between posterior condylar line (PCL) and APL (APA), angle between perpendicularity of APL and PCL (A-PA), posterior condylar angle (PCA), condylar twist angle (CTA), angle between clinical transepicondylar axis (CTEA) and STEA (CSA) were measured. These values were divided into different groups according to gender and side, the values of CTA, PCA, A-PA, angle PT (varus of tibia plateau), constant 3, ATA, APA and constant 90° were compared by statistically. A-PA and PCA, and CTA were analysed statistically with the liner regression, the relationship among CTEA, STEA ,PCL, APL and PLP were performed to assess by liner regression.

RESULTSATA was (89.79 ± 1.22)°, APA was (84.84 ± 1.83)°, A-PA was (5.16 ± 1.83)°, PCA was (4.80 ± 1.23)°, CTA was (8.23 ± 1.40), CSA was (3.45 ± 0.68)°. All the parameters had no differences on sex and side,but CSA had difference on male and female. There was no difference among angle PT, PCA, A-PA. There was significant difference in CAT, constant 30 and angle PT, PCA,A-PA. There was no difference between ATA and constant 90°, but there was difference between APA and constant 90°. There was relativity between PCA and CTA, and also PCA and A-PA, CTA and A-PA. There was significant relativity between STEA and CTEA, between STEA and APL, between STEA and PCL, and also between APLP, APL and PCL, but there was no significant relativity between PCL and CTEA.

CONCLUSIONTKA for Chinese, the section of femoral posterior condyle should be external 5° to obtain the optimum rotational orientation. The property is different entirely between STEA and CTEA, the rotational alignment is not performed according to parallel to the CTEA in distal femur. Among STEA, APL, PCL, the STEA is the most reliable mark ofrotational alignment of the distal femur, and the PCL is the less reliable mark.

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.

Objective To evaluate the safety and efficacy of bivalirudin in patients with acute myocardial infarction ( AMI) and diabetes undergoing primary percutaneous coronary intervention ( PCI) . Methods BRIGHT was a multicenter , randomized , controlled study which enrolled AMI patients underwent primary PCI in 83 Chinese centers between August 2012 and June 2013.All patients were randomly assigned to receive bivalirudin , heparin or heparin plus tirofiban. This study was a prespecified subgroup analysis of the BRIGHT study.A total of 465 diabetics in the BRIGHT study were included , consisted of 168 in the bivalirudin group , 137 in the heparin group and 160 in the heparin plus tirofiban group .Primary endpoint was net adverse clinical event ( NACE) at 30 days, which was defined as a composite of major adverse cardiac and cerebral events ( MACCE ) and any bleedings .Results The incidences of NACE at 30 days were significantly different among three arms ( Bivalirudin:10.1% vs.heparin:16.1% vs.Heparin plus tirofiban 20.6%, P=0.031 ) .Compared with heparin plus tirofiban , bivalirudin was associated with a significantly lower NACE rate (P<0.01).Bivalirudin treatment significantly reduced bleeding events at 30 days compared with heparin and heparin plus tirofiban ( 3.0% vs.7.3% vs.12.5%, P <0.01 ) .The 30-day incidences of MACCE and stent thrombosis were similar among the three groups ( P>0.05 ) . Conclusions The use of bivalirudin has dramatically reduced the rate of bleeding and did not increase the incidence of ischemic events compared with heparin and heparin plus tirofiban , indicating a better safety and efficacy profile of bivalirudin during primary PCI in patients with AMI and diabetes .
