OBJECTIVE： To observe the therapeutic effects of Bushen Yiqi （tonifying kidney to benefit qi）, Huoxue Huayu （promoting blood circulation to dissipate blood stasis） and Ditan Kaiqiao （eliminating phlegm for resuscitation） on the expressions of c-Fos and c-Jun proteins in hippocampus and spontaneous behaviors of rats with post-stroke depression （PSD）, and compare the results with those of fluoxetine, which is known to have definite effect on depression. DESIGN： A randomized controlled tna SETTING ： Zhejiang College of Traditional Chinese Medicine MATERIALS ： The trial was completed in Zhejiang College of Traditional Chinese Medicine from January to July in 2003. Fifty-six healthy adult Wistar male rats of clean grade, weighing （250±50） g, were randomly divided into 7 groups with 8 rats in each group： control group, model group, forced swimming group, Bushen Yiqi group; Huoxue Huayu, Ditan Kaiqiao group and fluoxetine group. The Bushen Yiqi Tang contained Renshen, Huangqi, Heshouwu, Gouqi, Shudi, etc., crude drugs 1 800 g/L. The Huoxue Huayu Tang contained Danshen, Chuanxiong, Chishao, Yujin, etc., crude drugs 3 600 g/L. The Ditan Kaiqiao Tang contained Banxia, Danxing, Changpu, Yuanzhi, etc., crude drug 1 000 g/b METHODS： ① Except the control group and forced swimming group, rats in the other groups were made into PSD models by deligating the bilateral common carotid artedes permanently. ② Rats in the control group, model group and forced swimming group were intragastncally perfused by saline （3 mL for each time）; those in the Bushen Yiqi group, Huoxue Huayu, Ditan Kaiqiao group and fluoxetine group were intragastncally perfused with Bushen Yiqi Tang （18 g/kg）, Huoxue Huayu Tang （9 g/kg）, Ditan Kaiqiao Tang （9 g/kg） and fluoxetine （2.5 mg/kg） respectively, once a day. ③ At 55 days after model establishment, rats in the forced swimming group were managed according to the Porsolt＇s method. They were placed in water for 15 minutes, and then taken out and dned, no moving-time within 5 minutes was recorded at drying and 24 hours after drying. ④ Measurement of spontaneous behaviors： Except the forced swimming group, the spontaneous behaviors and activities （including horizontal and vertical movements） of rats were observed with the Open-Field method at 28, 42 and 56 days after administration in the other groups. ⑤ The expressions of c-Fos and coJun proteins in hippocampus were determined with the immunohistochemical method, the relative sectional area ratio and average objective gray value of c-Fos and c-Jun positive cells in hip- pocampus were measured with the computerized image analytical system. MAIN OUTCOME MEASURES： The spontaneous behaviors of rats, the relative sectional area ratio and average objective gray value of c-Fos and c-Jun positive cells in hippocampus were observed. RESULTS： Of the 56 rats, 1 died in the forced swimming group, and finally 55 rats were involved in the analysis of results. ① Results of spontaneous activities： At 28 days, the times of crossing movements were obviously fewer in the model group and fluoxetine group [（69.00±37.01）, （98.11 ±36.68） times/3 minutes] than in the control group [（128.44±16.85） times/3 minutes, P 〈 0.01, 0.05], but those in the Bushen Yiqi group, Huoxue Quyu group and Ditan Kaiqiao group had no obvious differences as compared with those in the control group （P 〉 0.05）. At 42 and 56 days, the times of crossing movements were obviously more in the Bushen Yiqi group, Huoxue Quyu group and Ditan Kaiqiao group [（106.44±31.24）, （117.20±23.95）, （134.80±28.18）, （136.36±40.95） times/3 minutes; （117.33±35.91）, （129.60 ±23.78）, （131.90 ±26.81）, （136.09±28.34） times/3 minutes] than in the model group [（64.00±17.51）, （72.86±20.68） times/3 minutes, P 〈 0.01]. The times of rearing movements had no obvious differences among the groups for the three times （P 〉 0.05）. ② The no moving-time within 5 minutes 24 hours after drying was obviously longer than that at drying in the forced swimming group. ③ The average objective gray values of c-Fos positive cells were not obviously different in the Bushen Yiqi group and Ditan Kaiqiao group from the control group （P 〉 0.05）, but lower in the model group than in the control group （69.84±9.82, 75.78±5.89, P 〈 0.01）, and higher in the forced swimming group than in the control group （85.97±10.99, P 〈 0.01）; all higher in the fluoxetine group, Bushen Yiqi group, Huoxue Quyu group and Ditan Kaiqiao group than in the model group （81.27±10.73, 74.04±8.34, 83.29±9.89, 70.14±4.92, P 〈 0.05-0.01）. The average objective gray values of c-Jun positive cells were obviously lower in the Bushen Yiqi group than in the control group （68.11 ±6.89, 79.58±5.86, P 〈 0.01）, but all higher in the other groups than in the control group （84.68±7.15, 81.34 ±8.36, 97.51±10.55, 85.68±9.25, 86.19±10.98, P 〈 0.05-0.01）; Those were obviously higher in the fluoxetine group, Huoxue Quyu group and Ditan Kaiqiao group than in the model group （P 〈 0.05-0.01 ）, lower in the Bushen Yiqi group than in the model group （P 〈 0.05）, all obviously lower in the Bushen Yiqi group, Huoxue Quyu group and Ditan Kaiqiao group than in the fluoxetine group （P 〈 0.01）. The relative sectional area ratios of c-Fos and c-Jun positive cells had no obvious differences among the groups （P 〉 0.05）. CONCLUSION ： The methods of Bushen Yiqi, Huoxue Quyu and Ditan Kaiqiao can effectively treat PSD in rats, and the results were equivalent with those of fluoxetine, the actions of the above-mentioned drugs may correlated with their regulation to c-Fos and c-Jun expressions in hippocampus. PSD animal models can be successfully established by both permanent deligation of bilateral common carotid arteries and forced swimming, and the models induced by the former has similar basic cerebrovascular lesions as human stroke in clinic.展开更多

Herbal slice （HS） and Chinese patent drug （CPD） are commonly used CHM in China. This study aimed to investigate the utilization of CHM among clinicians and cancer patients in central China. Five hundred and twenty-five patients and 165 clinicians in 35 comprehensive hospitals in central China were asked to complete an anonymous questionnaire that was designed to evaluate the use of CHM. The results showed that 90.74% clinicians and 72.24% cancer patients used CHM during cancer treatment. The educational backgrounds of the clinicians and the age, education level, annual income, and cancer stage of the cancer patients were re- lated to use of CHM. More than 90% clinicians and cancer patients had used CPD. Comparatively, the percentage of HS use was 10% lower than that of CPD use among clinicians and cancer patients. More clinicians preferred to use CHM after surgery than cancer patients did （20.41% vs. 5.37%）. Enhancing physical fitness and improving performance status were regarded as the most potential effect of CHM on cancer treatment （85.71% among clinicians and 94.07% among cancer patients）, in comparison with directly killing tumor cells （24.49% among clinicians and 31.36% among patients）. As for refusal rea- sons, imprecise efficacy was the unanimous （100%） reason for clinicians＇ rejection of CHM, and 95.58% patients objected to using CHM also for this reason. Furthermore, the side effects of CHM were more concerned by clinicians than by patients （33.33% vs. 15.81%）. In conclusion, our survey revealed that CHM was popularly accepted by clinicians and cancer patients in central China. The reasons of use and rejection of CHM were different between clinicians and cancer patients.展开更多

However, acute or accumulative overdose of it can cause liver damage, even liver failure. Here we reported a case of an 11-year-old patient with acute liver failure （ALF） induced by taking 0.25 g APP orally, who was successfully treated by integrative Chinese and Western medicine.展开更多
