Traditional Chinese Drug Research & Clinical Pharmacology 2001;12(2):115-117
The technology,of extracting Semen Cassiae from Jueming Jiangzhi Powder was investigated.The perceutages of extra ction and preservation of anthraquinone were used to select the methods of extra ction, concentration and drying of Semen Cassiae. The optimal procedure was set as follows:the large-size powder of Semen Cassiae was extracted with 50% alcohol for three times, then the extracted liquid was concentrated by vacuum evaporati on and finally dried by spraying.

Objective To study the effect of psychological counseling for patients with thoracic surgery recovery period.Methods Ono hundred patients with lobectomy were selected,they were divided into experimental group and control group with 50 cases each according to the treatment method.Two groups of patients were in the ward completed indwelling catheter,inserted into the right double lumen endotracheal tube by high seniority anesthesiologists,postoperative given perfect analgesia.Two group patients were treated with routine operation before the visit,assess the condition and signed the anesthesia informed consent,the test group were given psychological support therapy,explain in detail postoperative recovery period may be uncomfortable,eliminate the anxiety of patients,establish the confidence to overcome the disease,Two groups of patients after surgery by the recovery room nurse to give psychological counseling,complete extubation and record the restlessness,24 h after the patient satisfaction questionnaire.Results In test group patients were able to follow instructions and coordinate nurse smooth tube removal,15 cases of patients need to brake,additional sedatives and dehyed extubation,the difference between the two groups has statistical significance (P < 0.05).The satisfaction questionnaire in test group was significantly higher than that in control group:100% (50/50) vs.82% (41/50),there was statistical difference (P < 0.05).Conclusion Psychological counseling can effectively avoid agitation in recovery period of patients with postoperative chest tube removal,smooth.

Objective To observe the intluence ot chemokine RANTES influence on cardiac allograft acute rejection caused by alloreactive memory CD4+ T cells (Tm) adoptive transfer.Methods Heterotopic heart transplantation (HTx) from Balb/c donors to C57BL/6 recipients was performed by anastomosis of the vessels of the neck.Mice undergoing heterotopic heart transplantation received either adoptive transfer of 1 × 106 CD4+ Tm from the spleen of alloantigen-primed C57BL/6 mice or no cells (control group).After the cardiac transplantation,the mean survival time (MST),mean histologic rank of rejection,relative gene expression and serum concentration of RANTES in the cardiac grafts.Results (1) The percentage of CD4+ Tm was 26.83% at the spleen of alloantigenprimed mice; (2) The MST was 5.17 ± 0.17 days in the CD4+ Tm+ HTx group versus 7.76 ± 0.21 days at the HTx group (control group) (P<0.01); (3) The histological tests revealed that mean histologic rank of rejection activity in the sections of cardiac allografts on the day 5 post grafting was grade 3.92 ± 0.08 in the HTx+ CD4+Tm group versus grade 2.67 ± 0.14 in HTx group (P<0.01) ;(4) The relative gene expression level of RANTES was 2.6 ± 0.21 in the CD4+ Tm + HTx group,significantly higher than in the control group (P<0.01) ; (5) The serum concentration of RANTES in the CD4+ Tm+ HTx group was 223.6 ± 16.79 pg/mL,higher than in the control group (120.7 ±9.47 pg/mL,P<0.01).Conclusion Alloreactive CD4+ Tm contribute to the increased expression and secretion of RANTES,and cardiac allograft acute rejection was more extensive in the CD4 + Tm + HTx group.

Objective To primarily explore the efficacy and adverse effects of the combination of fiudarabine,cytarabine and granulocyte colony-stimulating factor(G-CSF)(FLAG regime)therapy for relapsed and refractory acute leukemia in children.Methods Ten children were treated with the FLAG regime for relapsed and refractory acute myeloid leukemia (AML)and acute lymphoblastic leukemia(ALL)from Feb.2007 to Mar.2010.There were 8 male and 2 female,with mean age 8 years(ranging from 4 to 12 years).AML was diagnosed in 8 children,AML-M2 in 5 cases,AML-M4 in 3 cases.ALL was diagnosed in 2 children,both were B-ALL.Six children had refractory disease,and 4 cases were in relapse.FLAG regime included:fludarabine 25 mg?m-2?d-1,days 1-5;cytarabine 2 g?m-2?d-1,days 1-5;G-CSF 150-300 ?g?d-1,from day 0 to neutrophils ≥0.5?109 L-1.Results Complete remission was obtained in 6 children(60%),partial remission was obtained in 1 child(10%),and 3 children were considered non-response(30%).The total effective rate was 70%.For 8 children with AML,6 children had achieved complete remission(75%),2 children had non-response(25%).While in children with ALL,1 child got partial remission,and the other one had non-response.Myelosuppression and infections due to neutropenia were the most frequent adverse effects,severe nonhematologic toxicity were not observed in these children.And there were no chemotherapy-related death.Conclusions The FLAG regime is effective in treatment of children with relapsed and refractory acute leukemia,especially for the children with the relapsed and refractory AML.The adverse effects from this regime were well tolerated.FLAG regime can give children with relapsed and refractory acute leukemia another chance.

The reflective behaviors of teachers are a primary factor affecting teaching quality.However,the reflective behaviors of teachers can be propelled only by enhancing stimulus to teaching work,completing training system of continuing education on teaching theory and techniques to increase the teaching theory of teachers and performing teaching summarization of courses and assessment system.Only in this way can the teaching level and teaching quality of teachers be enhanced.

ObjectiveTo explore the characteristics of phonological encoding of Chinese disyllabic compound words in patients with mild cognition impairment(MCI). Methods10 patients with MCI and 10 normal controls who matched with the age, gender, level of education and handedness performed homophone judgment task. In this task, a picture with a disyllabic compound name was presented, after 100 ms of the presentation there would be a Chinese character below the picture. Subjects were asked to judge whether one of the morpheme in the picture name was homophonic to the character. The reaction time and error ratio were analyzed statistically. ResultsIn the normal controls, the reaction time for the second constituents was shorter than that for the first constituents, while there were no difference between the first and second constituents reaction time in MCI patients. The error ratio of the first and second constituents showed no difference in normal controls, but MCI patients made more error rate for the first constituents. ConclusionAs the heathy elderly,the MCI patients have same pattern in phonological coding of Chinese disyllabic compound words, but much slower in activation speed, indicating the impairment of semantic memory and phonological activation in patients with MCI.

Objective To investigate the levels of serum interleukin(IL)-18 in patients with chronic renal failure (CRF)and its relationship with relevant indexes. Methods Sixty patients with CRF were divided into three groups: patients with CRF (CRF group, n = 18) ,patients with bemedialysis (HD group, n = 22) and patients with peritoneal dialysis (PD group,n = 20). 20 healthy subjects were taken as controls. The levels of serum IL-18, tumor necrosis factor (TNF)-α and high sensitivity C-reactive protein (hs-CRP) were detected by means of ELISA. Serum albumin (ALB) ,total cholesterol (TC) ,triglyceride (TG) and serum creatinine (SCr) levels were detected by con-ventional means. The GFR was measured by using the abbreviated Modification of Diet in Renal Disease study (MDRD) equation. Differences in continuous variables between the three groups were evaluated. Results The lev-els of serum IL-18 were significantly increased in CRF[(497.7 ± 120.7) ng/L], HD[(538.1 ± 113.2) ng/L] and PD[(565.7 ± 122.1) ng/L] patients than those in healthy subjects[(163.9±42.2) ng/L] (P <0.01). Further-more,serum IL-18 levels in HD patients were higher than these in CRF patients (P <0.05). Serum IL-18 levels in CRF were positively related to serum TNF-α,hs-CRP and SCr(r =0. 636,0.436,0.367,P <0.01) ,and negatively related to GFR(r = -0.515 ,P <0.05). Conclusion The levels of serum IL-18 are markedly increased in patients with CRF,HD and PD,and related to the levels of TNF-α,hs-CRP and GFR,so IL-18 might be an important marker of sub-clinical inflammation in patients with chronic renal failure.
