To investigate the efficacy and adverse effects of venlafaxine in the treatment of depression, patients were given venlafaxine or amitriptyline for 6 weeks. The efficacy of the drugs were assessed by using HAMD and HAMA at the 4th, 7th, 14th and 42nd day before and after the medication. The adverse effects were evaluated by TESS. Our results showed that the effect time of venlafaxine was (8.52±4.47) d, which was fasler the that of amitriptyline. The effective rate of venlafaxine was 83%, which was faster the that of amitriptyline. but venlafaxine caused less dry mouth, constipation, blurred vusion, tachycardia and anorexia etc. It is concluded that venlafaxine worked faster with less side effect in the treatment of depression as compared with amitriptyline.

Objective To investigate the effects of cold exposure with different time courses on cardiovascular function and skeletal muscle contraction in Sprague-Dawley (SD) rats.Methods The male SD rats were randomly divided into control,12-h cold,24-h cold,and 48-h cold groups.The rats in all cold group were maintained in 4 ℃ environment for indicated time and allowed free access to standard rat chow and water ad libitum.After the animal model was established,the heart,thoracic aorta,soleus,and extensor digitorum longus (EDL) were rapidly isolated from rats under anesthesia and then fixed into the respective organ perfusion system that was connected to physiological recorders and data acquisition system.Lanendorff heart persusion was used to detect some parameters of cardiac function,such as coronary flow (CF),mean left ventricular systolic pressure (mLVSP),mean left ventricular diastolic pressure (mLVDP) and maximum ascending and declining rate of left ventricular pressure (± dp/dt max) ; and then the heart was suffered from 30 min ischemia followed by 60 min reperfusion,the changes of above cardiac function indexes were recorded again.Organ bath method was employed to detect contraction response to potassium chloride (KCl) or phenylephrine (PE) and endothelium-dependent relation responses to acetylcholine (ACh) of aortic rings.The twitch tension,titanic tension,and fatigue test of soleus and EDL were examined by electrical stimulation to reflect contractive function of skeletal muscle.Results The coronary flow (CF) were significantly reduced in 24-h and 48-h cold groups compared to control group [(9.0 ± 1.7) ml/g and (9.8 ± 1.3) ml/g vs (11.6 ± 1.2) ml/g,P < 0.05] ; 48-h cold exposure also showed significantly increased mLVSP (P <0.01) and mLVP (P < 0.05) of rats.After ischemia-reperfusion,the heart re-beat time was shorter in all cold exposure groups (all P < 0.01),mLVP and mLVDP were higher in 24-h and 48-h cold group than control group (all P < 0.01).The contraction of aortic rings responses to 60 mmol/L KCl [(0.63 ±0.13) g and (0.79 ±0.11)g vs (1.28±0.17)g,P <0.01] and 1 μmol/L PE [(0.62 ±0.18)g and (0.68 ±0.13)g vs (1.25 ± 0.18)g,P < 0.01] were decreased while the endothelium-dependent relaxation responses to low concentration ACh (3 × 10-8 ~ 3 × 10-7) were increased in 24-h and 48-h cold groups relative to control group (all P < 0.05).The 48-h cold also reduced titanic tension of SOL and EDL in comparison with control [(4.14 ± 0.62) N/cm2 vs (5.50 ± 0.75) N/cm2,P < 0.05 and (3.00 ± 0.57) N/ cm2 vs (4.70 ± 0.85) N/cm2,P < 0.01].Conclusions 24 ~ 48 h cold exposure could reduce CF but enhance the tolerance of heart from rats to ischemia reperfusion injury and also decrease the contraction of aortic rings response to KCl or PE but increase the sensitive responses to ACh of aortic rings from rats.The 48-h cold could decrease the contraction of skeletal muscle elicited by electrical stimulation.

Objective To evaluate anti-HEV IgG and IgM diagnostic kits with sera from convalescent hepatitis E patients and to establish the quantification method of detecting anti-HEV lgG.Methods Detect 42 convalescent serum samples of over 6 months after onset of hepatitis E patients from Jiangsu province with anti-HEV IgM and IgG diagnostic kits. Select and mix the anti-HEV IgG positive sera which were confirmed by Western blot with ORF2 and ORF3 antigen. The mixed serum was calibrated with a WHO anti-HEV Ig standard. A series quantitative linear standard was made for quantitative detection of anti-HEV IgG in hepatitis E vaccine clinical trials phase Ⅲ. Results The positive rates of the anti-HEV IgG di-agnose kits of G, K, MP, Wantai were 71.4%, 78.6%, 92.9% and 100% respectively. The positive rates of G was lower than that of MP (χ~2 = 5.19, P<0.05) and obviously lower than Wantai (χ~2 = 11.76,P<0.01). The positive rates of K was also obviously lower than that of Wantai (χ~2 =7.96, P <0.01).The positive rates of the anti-HEV IgM diagnose kits of MP, G, X, Wantai, K were 21.4%, 7.1%,21.4%, 64.3%, 78.6% respectively. The positive rate of both K and Wantai were obviously higher than that of MP(χ~2 = 15.75 ,P<0.01 ; X2 = 27.43 ,P< 0.01). With the Western blot confirmation test, 30 and 18 sera were reactive to ORF2 and ORF3 antigen separately. The anti-HEV IgG concentration of HEV-D01 mixed by 13 samples was 57.94 U/ml by the calibration. Prepare seven 1.5-fold dilution series of quantita-tive linear standard for HEV vaccine clinical trials phase Ⅲ, concentration range from 0.077 to 0.877 U/ml. The quantitive values of high, medium and low concentrations quality control samples lay in the range of average ± 2s, and the CV of quantitative values were 16%, 16%, 12% respectively. Conclusion The quality of different anti-HEY IgM and IgG diagnose kits were different. This study had set up a set of anti-HEV IgG linear quantitative standard, which fit for detecting anti-HEV IgG antibodies quantitatively in HEVvaccine clinical trial phase Ⅲ.

Objective To compare the sensitivity, specificity and consistency of five kits for quantitative detection of hepatitis B virus (HBV) DNA. Methods Four domestic fluorescence kits, A, B, C, and D, and Roche Cobas Ampliprep/Cobas TaqMan HBV test for quantitation of HBV DNA in serum, were applied to detect the National Standards, an additional plasma for sensitivity (7 times dilution), 15 plasma samples from healthy blood donor and 45 plasma samples from chronic hepatitis B patients. Results All five kits showed the correct results for the 9 positive specimens and 8 negative specimens from the National Standards. The quantitative results of specimens for sensitivity met requirements of the National Standards. The lowest concentration of HBV DNA by these three kits was 15.6 IU/mL. The lowest detection level of HBV DNA for domestic kit B was ≤500 IU/mL. There was linear correlation between the results by Roche kit and domestic kit C (r> 0.98). Kit D showed 2 false-negatives results in the 15 healthy blood donor samples. The coincidence rates between 4 domestic kits and the Roche kit ranged from 50% to 96% (A: 61%, B: 50%, C: 96%, D: 83 %). The consistency rate of kit C with the Roche kit was significantly higher than those of kit D, A and B (X2=5.62, P<0.05, X2=28. 93, P<0.01, X2=44.31,P<0.01, respectively). The consistency rates among these 5 kits were highest when testing samples with HBV DNA levels between 1×104-1×107 IU/mL. Conclusions The qualities of domestic kits vary remarkably and kit C has the greatest consistency rate with the Roche kit. Therefore, the qualities of domestic kits need to be further improved.
