Objective To explore the effect of bergamots volatile oil on relieving cough,asthma and eliminating phlegm in asthmatic rats and guinea-pig.Methods Bergamot essential oil was extracted by steam distillation,and the experimental guinea-pigs and mice were divi-ded into 3 groups with high,moderate and low doses of bergamot essential oil respectively(1.080,0.540,0.108 g?kg-1for guinea pig,1.753,0.877,0.175 g?kg-1 for mice).The other group were pre-treated with normal saline as model control group,and animals were fed with acute-brochisis-syrup,aminophylline,and xianzhuli oral-liquid as positive drug control groups.After the medication,the guinea pigs were sprayed with citric acid or histamine in a confined glass to induce cough or asthma,while the latent period of cough or asthma attack was detected.The mice were injected phenol red solution through the abdominal cavity,and the tracheal phenol red secretion volume was measured.Results The latent period of cough in high,moderate and low dose of bergamot volatile oil groups and acute-brochisis-syrup group were significantly longer than that of the model control group(Pa

Objective To report a case of deep mycosis caused by Rhizomucor chlamydosporus. Methods Medical history,histopathology and laboratory examination were investigated,and fungal identifi- cation by microscopy and culture as well in the patient.Results The patient,a 41-year-old male,initially presented with mild-tender and progressively aggravating masses on the right glutea,both groins,and back of the head of pancreas.Later,ulcer,necrosis,and black crusts developed at the primary lesions accompanied with nausea,vomitting and dysfunction of liver.Pathological examination revealed a chronic granuloma- tous inflammation in the dermis and subcutaneous tissue;and branching,nonseptate and broad hyphae in multinuclear giant cells,tissue spaces and blood vessel lumens,and,few PAS-positive septate hyphae as well as basophilic chlamydospores located in multinuclear giant cells.The isolate was identified as R. chlamydosporus.Conclusions The case of deep mycosis caused by R.chlamydosporus began with invasive granuloma,followed by necrotic ulcer,with condition aggravating rapidly,and the patient finally died of se- rious cachexia.

OBJECTIVETo compare the difference in the clinical efficacy on cervical spondylosis of vertebral artery type (CSA) treated with thermosensitive moxibustion at different dosages.

METHODSSixty cases of CSA were randomized into a saturated moxa dosage group and a regular moxa dosage group, 30 cases in each one. The thermosensitive moxibustion was adopted in the two groups. The mild suspended moxibustion was applied at two acupoints with the strongest thermosensitization. In the saturated moxa dosage group, the moxibustion time was determined by the disappearance of thermosensitization. In the regular moxa dosage group, 15 min was required on each acupoint. The treatment was given twice a day for first 4 days in the two groups. Since the 5th day, the treatment was given once a day, continuously for 10 times, and totally 14 days were required. The score of symptoms and function and clinical efficacy were compared between the two groups before and after treatment as well as 6-month follow-up after treatment.

RESULTSThe curative and effective rate was 56.7% (17/30) after treatment and 60.0% (18/30) in 6-month follow-up after treatment in the saturated moxa dosage group, which were superior to 26.7% (8/30) and 30.0% (9/30) in the regular moxa dosage group respectively (P < 0.01, P < 0.05). The scores of clinical symptoms and function after treatment and in follow-up were improved apparently as compared with those before treatment in both groups (all P < 0.01). The scores of clinical symptoms and function after treatment and in follow-up in the saturated moxa dosage group were increased much more apparently than those in the regular moxa dosage group (after treatment: 22.32 +/- 4.64 vs 17.43 +/- 3.21; in follow-up: 23.01 +/- 4.76 vs 18.32 +/- 2.13, both P < 0.01).

CONCLUSIONThe thermosensitization moxibustion of saturated dosage achieves the superior short-term and long-term efficacies in the treatment of CSA as compared with the regular moxibustion dosage.

Objective To evaluate the use of gated SPECT in patients with hypertrophic obstructive cardiomyopathy (HOCM) and the effects of percutaneous transluminal septal myocardial ablation (PTSMA) on myocardial perfusion.Methods 99 Tcm-methoxyisobutylisonitrile (MIBI) and 18F-fluorodeoxyglucose (FDG) images were performed in 31 HOCM patients before PFSMA and in 15 patients 3-7 d after PTSMA.The images in different left ventricular segments were analysed by using scores.Results In 99Tcm-MIBI images, uptake decreased at the septal regions in 12 HOCM patients (80.0%, 12/15) after PTSMA, 18F-FDG images also showed decreased uptake at the septal regions in 5 HOCM patients (33.3%, 5/15) after PTSMA.Conclusion 99Tcm-MIBI images might be an important method to evaluate PTSMA results, and 18 F-FDG images showed important value as reference.

This study was purposed to compare the significance of multiplex short tandem repeat polymerase chain reaction (STR-PCR) and fluorescent in situ hybridization (FISH) for monitoring chimerism after sex-mismatched allogeneic hematopoietic stem cell transplantation (allo-HSCT). The chimerism of bone marrow or peripheral blood cells from 38 patients was analyzed by STR-PCR and FISH on days 14, 28 and at 3 months after allo-HSCT. The results indicated that on day 14, the complete chimerism (CC) was detected in 14 of 30 cases by STR-PCR and in 8 of 30 cases by FISH (p > 0.05). On day 28, the CC was detected in 26 of 31 cases by STR-PCR and in 15 of 31 cases by FISH (p < 0.01). At 3 months, the CC was observed in 22 of 24 cases by STR-PCR and 17 of 24 cases by FISH (p > 0.05). 14 cases were found to have a graft rejection or relapse among 28 cases which were continuously monitored more than 3 months post the transplants. Donor cell decrease in 9 of 14 cases was proved by FISH alone. It is concluded that FISH is more sensitive than STR-PCR in early monitoring chimerism status of post-transplant and in predicting graft rejection or disease relapse.

AIMTo explore the roles of H1 and H2 receptors in the locus ceruleus (LC) in the carotid baroreflex (CBR) resetting resulted from foot-shock stress.

METHODSMale SD rats were divided into two groups (n=18) at random: unstressed and stressed group. The latter were subjected to unavoidable electric foot-shock twice daily for a week and each session of foot-shock lasted 2 hours. The left and right carotid sinus regions were isolated from the systemic circulation in all animals anesthetized with pentobarbital sodium. The intracarotid sinus pressure (ISP) was altered in a stepwise manner in vivo. ISP-mean arterial pressure (MAP), ISP-Gain relationship curves and reflex characteristic parameters were constructed by fitting to the logistic function with five parameters. The changes in CBR performance induced by stress and the effects of microinjection with histaminergic receptors antagonists into the LC on the responses of CBR to stress were examined.

RESULTSStress significantly shifted the ISP-MAP relationship curve upwards (P < 0.05) and obviously moved the middle part of ISP-Gain relationship curve downwards (P < 0.05), and decreased the value of the MAP range and maximum gain (P < 0.05), but increased the threshold pressure, saturation pressure, set point and ISP at maximum gain (P < 0.05). Microinjection of selective H1 or H2 receptor antagonist, chlorpheniramine (CHL, 0.5 microg/microl) or cimetidine (CIM, 1.5 microg/microl) into the LC, significantly attenuated the above-mentioned changes in CBR performance induced by stress and the alleviate effect of CIM was less remarkable than that of CHL (P < 0.05). The responses of CBR under stress to H1 or H2 receptor antagonist generally occurred 20 min after the administration and lasted approximately for 16 min. Microinjection with the same dose of CHL or CIM into the LC in the unstressed group did not change CBR performance significantly (P > 0.05). However, microinjection of CHL or CIM into the LC could not completely abolish the stress-induced changes in CBR.

CONCLUSIONThe stress results in a resetting of CBR and a decrease in reflex sensitivity. The stress-induced changes in CBR may be mediated, at least in part, by activating the brain histaminergic system. The H1 and H2 receptors in the LC, especially, Hi receptors may play an important role in the resetting of CBR under stress. The descending histaminergic pathway from the hypothalamus to LC may be involved in these effects. Moreover, the effects of stress on CBR also have other mechanisms.

OBJECTIVETo study the pathogenesis and the differential diagnosis of Castleman's disease.

METHODSHistopathology, immunohistochemical staining and clinical courses of 26 cases of Castleman's disease (CD) were studied with follow-up study of 16 cases.

RESULTSThe present study included 6 cases of multicentric type, 20 cases of localized type in the clinical aspects and 19 cases with hyaline vascular type, 4 cases with plasma cell type, 3 cases with mixed type in the histologic aspect. The Multicentric type presented systemic lymphadenopathy, anemia, hyperglobulinemia, hepatosplenomegaly, skin changes, and lung disorder and kidney disfunction, of which 1 case died of respiratory and renal insufficiency. 13 of the 20 localized cases were of the hyaline vascular type, and with good prognosis. 7 of the 20 cases showed paraneoplastic pemphigus associated with hyperglobulinemia (4/7) and lung disease (5/7). The pathologic features composed of proliferation of the mantle zone B cell, follicular dendritic cell, plasma cell and small vessels. In immunohistochemical staining, kappa and lambda light chains were detected in each CD case.

CONCLUSIONSMany diseases are similar to CD clinicopathologically. It is important to make differential diagnosis through pathological study. Castleman's disease is a lymphoproliferative disorder. The pathogenesis of this multicentric disorder may be associated with autoimmune disease.
