A success in reconstruction of the hematopoietic function of marrow in a case of malignant lymphoma attained by autologous peripheral blood stem cell transplantation after the ultra-high dose chemoradiotherapy was reported. The platelet count of patient was increased to over 20 ? 109/L at the eighth day after PBSC transplantation and was recovered to over 50?109/L at the tenth day after PBSC transplantation. The white blood cell count was increased to over 0. 5?109/ L at the ninth day after PBSC transplantation. The pelvic CT-graphy showed reduction in size of the tumor. And then the patient was outhospitalized due to remission,having been surviving for more than 6 months with routine follow-up. It was suggested that the autologous peripheral blood stem cell transplantation could be a safe and effective suplement therapy for radical cure of malignant tumor.

Objective:To evaluate the clinical efficacy and safety of Danhong injections in the adjuvant therapy for angina pecto-ris. Methods:According to a random number table,totally 120 cases of patients with angina pectoris were randomly divided into the observation group and the control group. The control group was treated with the conventional therapy,such as oxygen uptake,anti-in-flammation,expectoration and relieving asthma,and the observation group was treated with Danhong injections(30ml added in 250ml glucose infusions,ivd,qd)additionally. The treatment course was 2 weeks. The hemorheology and blood lipid changes before and af-ter the treatment were recorded,the ECG was analyzed and the clinical symptom improvement was evaluated in the two groups. Re-sults:After the treatment,the hemorheological indices of the two groups were significantly reduced(P<0. 01),and the improvement of the observation group was much better than that of the control group(P<0. 01). After the treatment,the TC,TG and LDL were significantly lower and the HDL was notably higher than those before the treatment in the two groups(P<0. 01),and the improvement of the observation group was significantly better than that in the control group(P<0. 01). The total efficiency of ECG and clinical symptom improvement in the observation group was significantly higher than that in the control group(P<0. 05). Conclusion:Dan-hong injections in the treatment of angina pectoris can significantly improve the hemorheology and blood lipid to enhance the clinical ef-ficacy,which are worthy of promoted application.

OBJECTIVE:To observe the efficacy and safety of amiodarone combined with valsartan in the treatment of paroxys-mal atrial fibrillation in elderly patients. METHODS:130 elderly patients with paroxysmal atrial fibrillation were randomly divided into observation and control group. Control group was orally given Amiodarone tablet 0.6 g in the first week,3 times a day,0.4 g in the second week,twice a day,0.2 g in the third week,twice a day;observation group was additionally given valsartan capsule 0.4 g in the first 1-3 day(s),once a day,the dose was increased to 0.8 g if patients showed no hypotension,once a day,and then decreased to 0.4 g if the pressure was lower than 100/60 mm Hg,once a day. The treatment course for both groups was 12 weeks. Clinical efficacy,and left atrium(LA),left ventricular end-diastolic volume(LVEDV),left ventricular systolic volume(LVESV), left ventricular ejection fraction (LVEF),heart rate,cardiothoracic ratio,systolic blood pressure,diastolic blood pressure before and after treatment,and incidence of adverse reactions in 2 groups were observed. RESULTS:Total effective rate in observation group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,LA, LVEDV and LVESV,heart rate,cardiothoracic ratio,systolic blood pressure,diastolic blood pressure in 2 groups were significant-ly lower than before,and observation group was lower than control group,LVEF was significantly higher than before,and observa-tion group was higher than control group,the differences were statistically significant(P<0.05). There was no significant differ-ence in the incidence of adverse reactions(P>0.05). CONCLUSIONS:The efficacy of amiodarone combined with valsartan is more obvious than only amiodarone in the treatment of paroxysmal atrial fibrillation in elderly patients,with similar safety.

Background and objectives Hyperhomocysteinemia is an independent risk factor for cardiovascular disease. Homocysteine thiolactone (HcyT), one of the homocysteine metabolites in vivo, is toxic both in vivo and in vitro. The aim of this study was to investigate the effect of HcyT on apoptotic damage in human umbilical vein endothelial cells (HUVECs) and the role of antioxidants in the reduction of HcyT-induced apoptosis. Methods HUVECs were cultured in DMEM supplemented with 20% heat inactivated fetal bovine serum cell cultures were maintained in a humidified 5% CO2 atmosphere at 37 ℃. Cytotoxicity was determined by MTT assay,which consists of hypodiploid cells with propidium iodide labeling and intracellular reactive oxygen species levels using 2',7'-dichlorofluorescein diacetate as the probe by flow cytometry. Results HcyT (250-2000μM) induced HUVECs apoptosis in a time- and concentration-dependent manner. Reactive oxygen species levels rose in response to increasing HcyT concentrations at 24-h incubation.The reduction of cell apoptosis by N-acetylcysteine, vitamin E, or pyrrolidine dithiocarbamate, occurred simultaneously with a significant decrease in intracellular reactive oxygen species levels. Conclusion HcyT exerts its cytotoxic effects on endothelial cells through an apoptotic mechanism involving cellular reactive oxygen species production. The capacity of N-acetylcysteine, vitamin E, and pyrrolidine dithiocarbamate to scavenge HcyT-induced cellular reactive oxygen species correlates well with their efficiency to protect against HcyT-promoted apoptotic damage. The protective effect of pyrrolidine dithiocarbamate on cell apoptosis indicates HcyT-generated hydrogen peroxide may provoke cell apoptosis via activating nuclear factor-kappa binding protein.

Objective To synthesize 2-(5-[18 F] fluoro-pentyl)-2-methyl-malonic acid (18 F-ML-10) and to investigate the biodistribution in mice and the primary clinical application.Methods 18F-ML-10 was synthesized by domestic synthesis module MF-2V-IT-1.Quality control of the probe was performed after automated synthesis.The biological characteristics of 18F-ML-10 were assessed by biodistribution assay on male Kunming mice and microPET imaging on a male SD rat.Six patients with brain metastasis (4males,2 females,and age 21-68 years) were enrolled in this study.18F-ML-10 PET images were acquired before and at 48 h after radiotherapy.SUVmean and SUVmax of ROI were calculated.GTV changes were measured by MRI before and 3 months after radiotherapy.Response of brain metastasis to radiotherapy was assessed by PET imaging with 18F-ML-10.Two-sample t test was used.Results The non-corrected radiochemical yield of 18F-ML-10 was (26.5±7.3)％ with acceptable quality.The radiochemical purity exceeded 99％.18F-ML-10 was excreted through the kidneys,and the radiouptake in the blood was declined rapidly.The radiotracer accumulation was low in most of other organs.The testis showed a significant uptake.The SUVmean and SUVmax after radiotherapy (5.54±2.72 and 7.29±3.09) were significantly higher than the baseline values(3.81±1.13 and 4.97±1.05;t=2.670,2.663,both P＜0.05).The GTV after radiotherapy was significantly lower than the baseline value:(13.14±9.39) cm3 vs (23.34± 18.13) cm3;t =3.002,P＜0.05.Conclusions 18F-ML-10 could be synthesized reliably and repeatedly by domestic synthesis module.It has satisfactory properties in vivo and is probably suitable for early assessment of the response to radiotherapy in patients with brain metastasis.

Objective Adipsic hypernatremia is very rare in clinical practice and only a few cases have been reported so far. Since the pathogenesis of adipsic hypernatremia is unclear, therapeutic method is very limited and uncertain. We previously found the existence of partial central diabetes insipidus in the patient with adipsic hypernatremia according to a series of clinical studies. In this clinical study, we observed the response of vasopressin in the treatment of adipsic hypernatremia as a routinely used agent in treating central diabetes insipidus.Methods Five patients with chronic sustained hypernatremia and hypodipsia were diagnosed as adipsic hypernatremia according to the criteria by Halter. After testing plasma electrolytes, urinary osmolality, plasma osmolality, and free water clearance (CH2O);with evaluating thirsty grade and anterior pituitary function, patients were forced to drink water 2 000-2 500 ml each day combined with prednisone and/or levethyroxin supplementation therapy if hypopituitarsm was revealed. One week later, since the hypernatremia was unrelieved, desmopressin acetate (0.05-0.2 mg/d)was administered to those 5 patients. About 5-7 days later, plasma electrolytes, urinary and plasma osmolality, and free water clearance ( CH2O ) were reevaluated. Osmolality was detected by the method of freezing point depression and thirst grade by the method of visual analogue scales. Results The plasma sodium was 160-190 mmol/L and plasma osmolality was 330-370 mmoL/L without thirsty perception during the hospitalization. Four of the five patients were revealed to be suffering from hypopituitarism, but the hypernatremia could not be corrected by intentional water intake combined with prednisone treatment. After administering vasopressin 0.05-0.2 mg/d to these patients, that hypernatremia was relieved, and hyperosmolality and hypodypsia were improved effectively. During this period of time, no side effects were detected in these patients. Conclusion We testified the existence of central partial diabetes insipidus in the patients with adipsic hypernatremia. Desmopressin acetate in the treatment of adipsic hypernatremia is proved to be effective, simple, and safe.
