OBJECTIVETo explore the effect of Danggui Yinzi (DY) on delayed allergy in model mice with qi-blood deficiency syndrome (QBDS).

METHODSQBDS model was established in 48 Kuming mice of SPF grade by using reserpine and acetophenone hydrazine. Forty of them were then randomly divided into the model group, the loratadine group, the high dose DY group, the middle dose DY group, and the low dose DY group, 8 in each group. Another 8 in line with the same standard were recruited as a blank group. Mice in high, middle, and low dose DY groups were administered with DY concentrated solution at 60, 30, 15 g/kg by gastrogavage. Mice in the loratadine group were administered with loratadine solution at 1.66 mg/kg by gastrogavage. Equal volume of normal saline was administered to mice in the model group and the blank group by gastrogavage. All medication was given once per day for 1 successive week. Except those in the blank group, the rest mice were evenly smeared with 1% DNCB solution on the abdomen. Five days after skin allergy, 1% DNCB solution was smeared to right ear of all mice to stimulate allergic reaction. Mice in the blank group were smeared in the same way without allergenic reaction. The auricle swelling and the inhibition ratio were determined at 24 h after attack. Blood was collected from orbit and serum IgE level detected using double-antibody sandwich ELISA.

RESULTSCompared with the blank group, auricle swelling obviously increased and serum IgE level was obviously elevated in the model group (P < 0.01). Compared with the model group, auricle swelling obviously decreased and serum IgE level was obviously reduced in the 3 dose DY groups (P < 0.05, P < 0.01). Meanwhile, the auricle swelling degree was superior in high and middle dose DY groups to that in the loratadine group (P < 0.05). The inhibition ratio of auricle swelling was sequenced from high to low as 67.3% in the high dose DY group, 56.0% in the middle dose DY group, 48.1% in the low dose DY group, 47.3% in the loratadine group.

CONCLUSIONSDY could inhibit auricle swelling and lower serum IgE level. It also could inhibit delayed allergic reaction in model mice with QBDS to some extent.

OBJECTIVETo investigate risk factors associated with acute tumor lysis syndrome (ATLS) in children with B-cell lymphoma and to explore feasible means for the prophylaxis and treatment.

METHODData from 18 children with ATLS in B-cell lymphoma were collected to assess their tumor burden at diagnosis and before chemotherapy. Evaluation was performed at the 8th day, 3 month, and the end of chemotherapy and follow up. The incidence of ATLS in B-cell lymphoma, and the relationship between the incidence of ATLS and whether the kidney was involved and large tumor burden were analyzed respectively. All patients received hydration, alkalinization and received allopurinol routinely. Urate oxidase and hemodialysis treatment were administered in some cases.

RESULTOf the 103 children with B-cell lymphoma, 18 were diagnosed as having ATLS (17.5%). All the 18 cases with ATLS were histopathologically confirmed as having Burkitt's lymphoma. All the patients were at stage III or IV and all had large tumor sizes, and 7 were found to have blasts in the bone marrow>25% (38.9%). Lactate dehydrogenase (LDH) levels≥1000 U/L were found in 11 (61.1%) cases. All patients had developed metabolic abnormalities, including hyperuricemia, hyperphosphatemia, hypocalcemia, and uremia. In terms of clinical features and prognosis, all cases had nausea, vomiting, anorexia, oliguria, and anuria at different levels. One had gastrointestinal bleeding, 7 patients experienced seizures. The etiology in five was hypocalcemia and two had reversible posterior encephalopathy syndrome and all responded well to treatment. Nine cases of ATLS responded to supportive care, 4 required hemodialysis, and the other 4 responded to urate oxidase. Ten cases survived and 8 died. The major cause of death was severe complications and treatment was given up in 5 cases and recurrence occurred in 3 cases.

CONCLUSIONATLS was commonly seen in Burkitt's subtype of B-cell lymphoma. Higher LDH and large tumor sizes and kidney involvement were important risk factors for the development of ATLS in children with B-cell lymphoma. Treatments with hydration, alkalinization and allopurinol were safe and effective. Urate oxidase and hemodialytic treatments should be given timely.

Resveratrol, as a natural polyphenolic compound, has a wide range of beneficial effects, which includes anti-tumor, cardiovascular protection, anti-oxidant and estrogen-like effects, and so on. Its various physiological properties are closely related to the therapeutic principle for prevention and treatment of high altitude hypoxia injury. Resveratrol may play an important role in relieving or curing high altitude diseases, especially high altitude polycythemia(HAPC). However, the literature about study and application of resveratrol in plateau medicine field is rarely reported up to now. In this review, we summarized the physiological effects of resveratrol, discussed the possible main principle of resveratrol for HAPC therapy, and looked forward to resveratrol's perspective or potential application in high altitude medicine.

Objective To evaluate the effect of hyperhomocysteinemia on ischemic diease in rats. Methods Thirty-two SD rats were randomized into two groups,control group(n=16,administered with tap water) and hyperhomocysteinemia group(HH group,n=16,administered with water containing L-methionine at 1 g/kg/d).At the 14thday of dietary modification,the left femoral artery and vein were excised,and the interventions continued for another 14 days.At the 15th day after operation,serum biochemical parameters as well as NOx and cGMP in ischemic tissues were tested,capillary vessel density of both hindlimbs were measured by histological analysis,and angiogenesis of ischemic hindlimb was observed by angiography. Results At the 15th day after operation,the level of high-density lipoprotein-cholesterol(HDL-C),blood urea nitrogen,uric acid and ratio of blood urea nitrogen to serum creatinine were significantly higher in HH group than those in control group,while the level of serum folic acid,VitB12,HDL-C and endogenous creatinine clearance rate were significantly lower in HH group than those in control group(P

OBJECTIVETo summarize the clinical features and to evaluate outcomes and to assess therapeutic effects in 34 children and adolescents with Hodgkin lymphoma treated with risk-adapted combination chemotherapy and low-dose, involved-field radiation therapy (IFRT) in China.

METHODFrom January 2003 to April 2009, 34 hospitalized children with Hodgkin lymphoma were enrolled into the BCH-HL 2003 protocol (revised CCG 5942) in our hospital. Pathological samples were reviewed centrally and classified based on the World Health Organization guidelines. Staging was based on clinical evaluation and was defined by the Ann Arbor staging system. The 34 patients were treated according to the different risk factors in three treatment groups (standard, intermediate, and high risk), and received risk-adapted combination chemotherapy and IFRT. All analyses were calculated by the statistical program SPSS.

RESULTOf the 34 Hodgkin lymphoma patients, 28 were male and 6 were female. The median age was 8.7 years (range from 4 years to 15 years) at the time of diagnosis. In terms of clinical presentation, 53% had bulky lymph nodes, 47.1% had more than 4 node regions involved and 44% had "B" symptoms at presentation. The distribution for stage of disease was 0% for Stage I, 21% for Stage II, 35% for Stage III and 44% for Stage IV disease. All patients had classical histology consisting of three different sub-discipline: 22 cases of mixed cellularity (64.7%). In pathological samples of 25 cases there was EBV encoded RNA (EBER) or latent membrane protein (LMP) staining. The overall survival (OS) was 100% and the 5-year event-free survival was 94.1% with a median follow-up of (26.1 ± 16.3) months. Two patients had early relapse after treatment was finished. Organ toxicity was limited to hematological grades III and IV at rates of 40% and 71% respectively.

CONCLUSIONChildhood Hodgkin lymphoma in our study was more frequently seen in male school aged children. Combined-modality therapy using risk-adapted chemotherapy with radiation is effective and well tolerated. The overall prognosis was good.

OBJECTIVETo investigate the effects of simple hypobaric hypoxia on parameters of hematology and blood rheology in order to establish a rat model of simulated high altitude polycythemia (HAPC) for the study of pathophysiologic mechanisms and medical prevention and treatment of HAPC.

METHODSForty-eight male Wistar rats were randomly divided into three normal control groups and three hypoxia model groups. Normal control group rats were bred in normoxia conditions, and hypoxia group rats were subjected to hypoxic exposure for 8 hours per day at simulated 5 500 m high altitude in a hypobaric chamber. After hypoxic exposure for 2, 4, 12 weeks, one group of normal control and hypoxia model rats were killed and blood was collected, respectively. Then parameters of erythrocyte and blood rheology were examined.

RESULTSMucous membrane of hypoxia model rats showed obviously cyanosis after 2 weeks hypoxic exposure. Hemoglobin concentration of hypoxia model rats were beyond 210 g/L after 2 weeks, 4 weeks and 12 weeks hypoxia exposure and significantly increased than that of normal control rats respectively. Besides, RBC counts, hematocrit, whole blood viscosity, erythrocyte aggregation index of hypoxia model rats were all notably higher than those of normal control rats respectively.

CONCLUSIONA rat model of high altitude polycythemia can be rapidly established by hypobaric hypoxia exposure at simulated 5 500 m high altitude for 8 hours daily.
