OBJECTIVE:To study the use and developmental tendency of psychotolytics in hospitals of Guangdong province.METHODS:The psychotolytics used in hospitals of Guangdong province during the period of2000～2004were an-alyzed statistically in respect to consumption sum,DDDs and average daily expense.RESULTS&CONCLUSIONS:Both consumption sum and DDDs of psychotolytics in the past5years increased to a large extent.Benzodiazepine topped the list of anti-anxiety drugs.The consumption of2nd generation antipsychotics increased year by year.On the whole,the consumption of antidepressants increased annually,of which,fluoxetine,flupentixol/melitracen and paroxetine were the most frequently used drugs.However,the consumption of tricyclic antidepressants has a significant reduction.

ObjectiveTo investigate the significance of synchronic heart rate variation(HRV) and blood pressure variation(BPV) in the evaluation of coronary artery disease(CAD).MethodsOne hundred and three patients who received coronary artery angiography were divided by the lesion degree into occlusion group (28 cases with more than 1 complete-occlusion coronary artery),non-occlusion group (45 cases with more than 1 coronary artery stenosis ≥50％ but without complete-occlusion) and control group (30 cases without stenosis ≥50％).Occlusion group and non-occlusion group were divided by lesion location into left anterior descending (LAD) lesion (32 cases),left circumflex ( LCF ) lesion (23 cases ) and right coronary artery(RCA) lesion (18 cases).And these two groups were also divided by lesion branch number into 1 lesion branch (23 cases),2 lesion branches (19 cases) and 3 lesion branches(31 cases).The time domain indexes of HRV were detected and calculated by 24 h dynamic blood pressutre and ECG,including standard deviation of normal number of R-R intervals (SDNN),standard deviation of per 5 min average normal R-R intervals(SDANNind),24 h average of standard deviation of per 5 min normal R-R intervals(SDNNind),root mean square of standard deviation of adjacent normal R-R intervals (rMSSD),and percentage of the difference of adjacent normal R-R intervals ＞ 50 ms (PNN50).And indexes of BPV were detected,including daytime systolic pressure standard deviation (dSSD),daytime diastolic pressure standard deviation (dDSD) and nighttime systolic blood pressure standard deviation (nSSD).The correlations between synchronic HRV and BPV and different coronary artery lesions were analyzed.ResultsSDNN,SDANNind significantly decreased and dSSD obviously increased with the aggravation of coronary stenosis,and there was statistical significance[ ( 115 ± 35 ) ms vs.(98 ± 25 ) ms vs.( 78 ± 28 ) ms,( 100 ± 30) ms vs.( 86 ± 23 ) ms vs.( 70 ± 29 )ms,(14 ± 3) mm Hg (1 mm Hg=0.133 kPa) vs.(20±4) mm Hg vs.(28±2) mm Hg](P＜0.05).rMSSD and PNN50 decreased,dDSD and nSSD increased with the aggravation of coronary artery stenosis,but there was no statistical significance (P＞0.05).SDNN and SDANNind in patients with LAD lesion and LCX lesion were significantly lower than those in control group,and dSSD was obviously higher than that in control group (P ＜ 0.01 or ＜ 0.05 ).SDANNind,rMSSD,PNN50,dDSD and nSSD in patients with LAD lesion and LCX lesion had no significant difference compared with those in control group (P ＞ 0.05 ).SDNN,SDANNind,SDNNind,rMSSD,PNN50,dSSD,dDSD and nSSD in patients with RCA lesion had no statistical significance compared with those in control group ( P ＞ 0.05 ).All the indexes of HRV tended to descend and indexes of BPV trended to raise with the increasing number of coronary artery lesion branches.But only the changes of SDNN,SDANNind,SDNNind,rMSSD,PNN50 and dSSD had statistical significance (P ＜ 0.05).Conclusions The more significantly HRV decreases and dSSD increases in patients with coronary artery disease,the more serious the coronary artery stenosis is and the wider the lesions are.The lesions are commonly located in LAD.It has certain guiding value for the evaluation of coronary artery diseases.

Peroxisome proliferator activated receptor-γ (PPARγ) is a member of the nuclear receptor superfamily of ligand-activated transcription factors that plays a critical role in regulating glucose and lipid homeostasis,and in the processes of tumor cell proliferation,differentiation,apoptosis,invasion and distant metastasis.Studies demonstrate that PPARγexpression is detected in human lung cancer tissues and numerous lung cancer cell lines.Activation of PPARγthrough its ligands impedes significantly a variety of tumor progression,including lung cancer.However,systemic activation of PPARγhas been reported to be protumorigenic in some in vitro systems and in vivo models.

Objective To find ways to reduce vascular crisis of the patients undergoing replantation of severed fingers by pain, adverse analgesics and sleep quality with auricular seeds pressing. Methods 310 digital replantation patients were divided into 2 groups according to admission time. There were 155 cases in the traditional group treated with routine postoperative care ,while 155 cases in the controlled group treated with routine postoperative care plus auricular seeds pressing. Results The scores of pain, adverse analgesics and sleep quality in two groups were statistically significant ( P<0.05). The rate of vascular crisis of the traditional group [18.06%(28/155)] was much more higher than the controlled group [5.16%(8/155)], the difference was significant, χ2=12.571, P < 0.01. Conclusion In digital replantation, auricular seeds pressing was effective to pain relieving, constipation and reduce adverse reactions, and could significantly improve sleeping time and survival rate of the severed fingers.

Objective To study the influences of endogenous testosterone on vascular endothelial cell function and structure in rabbits of balloon injury. Methods Twenty male rabbits were randomly divided into two groups: castrated group and control group.The former group animals were castrated and the later group animals received sham operation. All animals were performed with deendothelializing balloon injury in the right iliac artery. Nitric oxide (NO) and endothelin-1 (ET-1) were measured at different intervals during the experiment. After 2 weaks of endothelial denudation all animals were killed, and endothelin structure and morphological changes were observed with electron microscope and HE staining. Results There weren′t siginificant differences of plasma NO and ET-1 levels between the two groups, but plasma NO and ET-1 levels of the castrated group 2 weaks after endothelial denudation recovered to the levels before castration, while they didn′t in the control group. The extent of reendothelialization and intimal area of the harvested segments were similar between the two groups. Conclusion The decrease of endogenous testosterone level did not affect endothelial cell structure, but tended to protect function of injured endothelium.
