Armillariella mellea polysaccharide ( AP ) was isolated from solid fermented Armillariella mellea. AP ( 100 mg/kg?d, ig ? 5 d ) increased the production of serum hemolysin in normal mice as well as in im-munodepressed mice induced by cyclophosphamide. At the dose of 50 mg/kg?d ig?5d, AP also caused a significant increase of spleen plaque forming cells ( PFC ) in normal mice. AP ( 10, 50?g/ml ) markedly enhanced Con A-induced lymphocyte proliferation of mouse spleen cells in vitro, but it had no potentiating effect on delayed cutaneous hypersensitivity ( DCH ) to 2,4-dinitrochlorobenzene ( DNCB ) in normal mice. AP ( 100 mg/kg/d, sc? 7d) increased both clearance rate of iv charcoal particles and phagocytic activity of ma-crophages of abdominal cavity in normal mice.

Objective To investigate the different clinical behavior and the diagnosis and trearment of primary hyperparathyroidism(PHPT). Methods Clinical data of 53 patients with PHPT treated in Beijing Jishuitan Hospital from May 1977 to April 2004 were collected and analyzed. Results 53 patients with PHPT were confirmed by operation and pathology. The majority of the patients were aged 20~50 years. There were more female than male patients. There were various clinical manifestations, and the duration of illness was (protracted). Many cases were misdiagnosed. There were bone pathologic changes of varying extent in all (patients), stones in urinary system plus bone pathology in 11 cases, serum level of calcium was raised in 51 patients(96.2%) and (parathyroid) hormone (PTH) was elevated in all examined 48 cases. Ultrasound, MIBI and CT were done before operation after 1991, and accurate preoperative localization diagnosis was (obtained). Minimally invasive (parathyroidectomy) (MIP) was successfully completed in 39 of 45 cases, and the primary operation cure rate was 97.4%. At postoperative follow-up of 10 months to 10 years, with the (exception) of 15 cases of severe bone deformity that had no obvious improvement, the other symptoms and signs were all relieved to varying (extents), the laboratory markers returned to normal, and there was no permanent hypoparathyroidism or (recurrent) nerve injury or other complications.Conclusions Early diagnosis of PHPT and effective early (treatment) by surgical removal of the pathologic lesion can alleviate the occurrence of severe bone changes and deformity. The preoperative combined use of imaging localization technique and overall assessment can improve the accuracy of diagnostic localization of the lesion.

AIM: To investigate the effect and mechanism of 5-aminosalicylic acid (5-ASA) in topical treatment on trinitrobenzene sulfonic acid (TNBS)-induced colitis in rats. METHODS: Colitis was induced by intracolonic administration of TNBS and was treated with 5-ASA at the dose of 100 mg?kg -1 for 2 weeks. Normal control group was administrated with normal saline and TNBS control group was treated with TNBS, not with 5-ASA. Macroscopic damage, histological changes and myeloperoxidase (MPO) activity were evaluated. Superoxide dismutase (SOD) activity and malondialdehyde (MDA) level in colonic mucosa were detected by kits. The expression of interleukin-1? (IL-1?) and tumor necrosis factor-? (TNF-?) mRNAs in colonic mucosa was determined by a reverse transcription and polymerase chain reaction method. RESULTS: Compared with TNBS control group, the macroscopic and histological changes and MPO activity in 5-ASA treated groups were improved. SOD activity was increased and the level of MDA in colonic mucosa was reduced significantly. The expression of IL-1? and TNF-? mRNAs in colonic mucosa was also decreased significantly. CONCLUSION: 5-ASA enema can significantly ameliorate TNBS-induced colitis in rats via antioxidant mechanism and attenuation of proinflammatory cytokine expression.

AIM: To observe the therupeatic effects of Shemai Zhusheye vs vitamine C injection in treating dilated cardiomyopathy (DCM).　METHODS: Fifty-two patients with DCM were divided into 2 groups, 32 patients in treatment group (M 20, F 12; age 46 a± s 13 a), 20 patients in control group (M 11, F 9; age 47 a±14 a). Besides the patients in two groups were treated with conventional therapy, the patients in treatment group were given Shenmai Zhusheye 30 mL and 5% glucose injection 100 mL, iv, gtt, qd for 2 wk. The patients in control group were given vitamine C 5.0 and 5% glucose injection 100 mL, iv, gtt, qd for 2 wk. 　RESULTS: Treatment group total effective rate was 84%. Control group total effective rate was 65% (P>0.05).　CONCLUSION: Shenmai zhusheye has better effect in treating DCM. Symptom improving rate of Shenmai Zhusheye has better than vitamin C.

Objective To characterize clinical features and prognosis of pediatric cutaneous mastocytosis. Methods Clinical data on 183 cases of pediatric cutaneous mastocytosis were collected and retrospectively analyzed. Some patients were followed up. Results Of the 183 patients, 136 (74.3%)had urticaria pigmentosa, 43 (23.5%) mastocytoma, 4 (2.2%)diffuse mastocytosis. The first attack of mastocytosis occurred at birth in 21 (48.8%)patients with mastocytoma and 35(25.7%)patients with urticaria pigmentosa, within 6 months after birth in 17(39.5%)patients with mastocytoma and 78(57.3%)patients with urticaria pigmentosa, and within 2 years after birth in 179(97.8%)out of the 183 patients. Of 33 patients with detailed description of symptoms, 10 had concomitant symptoms, which were flushing in 9 patients. Forty-five patients were followed up for 3 - 6 years (average, 4 years). The follow-up showed that skin lesions completely regressed in 1 patient with urticaria pigmentosa at 11 years of age, partially regressed in 18 patients. Lesions regressed completely at 8 years of age in 1 patient with mastocytoma, and subsided within 1 year after skin biopsy in 7 patients. Oral antihistamines could control the symptoms of mastocytosis, such as flushing, whealing and blistering, and oral glucocorticoids could effectively control the recurrence of generalized blisters and bullae in patients with diffuse mastocytosis. Conclusions Urticaria pigmentosa appears to be the most common type of cutaneous mastocytosis in children, followed by mastocytoma. Mastocytoma occurs most frequently at birth, while urticaria pigmentosa within 6 months after birth. Oral antihistamines may control inflammatory mediator-related symptoms. Serious diffuse mastocytosis may be controlled by systemic glucocorticoids.
