Objective To improve the understanding of systemic mastocytosis(SM) with associated clonal haematological non-mast-cell lineage disease (SM-AHNMD). Methods The clinical and laboratory features, treatment and prognosis of a rare case of SM-AHNMD was reported and the related literatures were reviewed. Results As the second most common subtype of SM, SM-AHNMD mainly has multifocal dense infiltrates of mast cells detected in sections of bone marrow and/or other extracutaneous organs, and some special cytology or biochemical markers(toluidine blue staining,tryptase,CD117,CD25 and/or CD2) results are positive. C-kit mutations are found in most adult patients. SM-AHNMD also has clinical characters of other clonal haematological non-mast-cell lineage disease (HNMD), such as myelodysplastic syndrome,myeloproliferative neoplasms, acute myeloid leukemia. Conclusion SM-AHNMD meets criteria for SM and other HNMD. Treatment for SM-AHNMD is mainly about the therapy of HNMD, and the prognosis greatly depends on the accompanying hematological disorder.There is no special treatment for SM,and the treatment should be directed at symptomatic control.

OBJECTIVETo evaluate the short effect and safety of the acupoint application of dog days for allergic rhinitis.

METHODSTwo hundred and forty-nine patients were randomly divided into an application group (166 cases) and a placebo group (83 cases). On the first day of the first dog days, the first day of the second of the three ten-day periods of the hot season and the first day of the last of the three ten-day periods of the hot season, acupoint application was adopted mainly at Dazhui (GV 14), Feishu (BL 13), Pishu (BL 20) and Shenshu (BL 23) in the application group. The plaster was made of Chinese herbs, including Baijiezi (semen brassicae), Xixin (asarum), Yanhusuo (corydalis tuber) and Gansui (euphorbia kansui). Buckwheat plaster without medical ingredient was used in the placebo group. The application was pasted for 2-6 h every time. On the first three days of all the three periods of dog days, treatment was used continuously. The whole period of dog days was made into one course. The changes of symptom and syndrome scores, visual analogue scale (VAS) for symptom before and after treatment and the adverse reaction with the condition disposed were observed in the two groups.

RESULTSAfter treatment, the symptom and syndrome scores and VAS for symptom were improved compared with those before treatment in the two groups (all P < 0.05), and the improvements of the application group were more obvious than those of the placebo group (all P < 0.05). The short effective rate of the application group was 68.1% (113/166), which was better than 48.2% (40/83) of the placebo group (P < 0.05). The adverse reaction rates were 4.2% (7/166), 2.4% (2/83) respectively, with no statistical significance between the two groups (P > 0.05).

CONCLUSIONThe dog days plaster achieves obvious effect with good safety for allergic rhinitis.

Objective To compare the dexmedetomidine and midazolam administered intranasally for preoperative sedation in the pediatric patients undergoing neurosurgical procedures.Methods Forty pediatric patients of both sexes, aged 2-7 yr, weighing 1 1-26 kg, of American Society of Anesthesiology Anesthesiologists physical status Ⅱ, were equally and randomly assigned into either midazolam group (group M) and dexmedetomidine group (group D).Group M received midazolam 0.2 mg/kg administered intranasally, and group D received dexmedetomidine 2 μg/kg administered intranasally in the room for preoperative preparation.The pediatric patients were separated from their patients at 30 min after administration.Oxygen was inhaled by mask after admission to the operating room, and venipuncture was performed.The responses to nasal mucous membrane irritation and separation from their parents were recorded.Ramsay sedation scores were recorded when the patients were separated from their parents.The occurrence of bradycardia, hypotension, hypertension and hyoxemia was recorded from the end of administration until venipuncture.Results The pediatric patients were successfully separated from their patients in the two groups.Compared with group M, the incidence of responses to nasal mucous membrane irritation was significantly decreased, and Ramsay sedation scores were increased in group D (P＜0.05).No pediatric patients developed adverse reactions such as bradycardia, hypotension, hypertension and hyoxemia in the two groups.Conclusion Dexmedetomidine administered intranasally provides better efficacy than midazolam when used for preoperative sedation in the pediatric patients undergoing neurosurgical procedures.

Objective To evaluate the efficacy and toxicity of hyperthermia combined with chemoradiotherapy for local advanced cervical cancer. Methods Sixty-eight patients with local advanced cervical cancer were treated. Each patient was given cisplatin at the dose of 20 mg ivgtt dl -2 and 5 -fluorouracil 0.75 ivgtt dl -2, repeating every week, total 3 weeks. Thirty -eight patients received chemoradiotherapy alone. Thirty patients received hyperthermia with deeply focus technology, the temperature was increased and maintained 42.5 ℃ for 30 min at least, within 2 hours following irridiation. Hyperthermia was given twice per week with 7 or 12 sessions, as the same chemoradiation methods as the reference group.After 40 Gy therapy to estimate by cervical examination and ultrasonography, the patients with down stage were for operation, and the others continued to irridiation and additional brachytherapy with californium 252until radical dose. Results All patients were tolerated, fifteen patients of hyperthermia combined group were operated and ten patients of the reference group were operated, the difference was significance (50.0 % vs.26.3 %, P <0.05). The response rate of the combined group was 90.0 %, and the reference group was 84.2 %.The incidence of radiotherapy toxicity of the combined group was not higher than the reference group.Conclusion Hyperthermia combined with chemoradiotherapy can elevate the resection rate and the local control rate, not increase the radiotherapy toxicity and increase quality of life for cervical cancer patients.

Objective The purpose of this study was to investigate the effect of blood supply decrease on glycosaminoglycans(GAG)of the cartilage in the temporomandibular joint(TMJ) . Method Four rabbits were used as controls, and 16 rabbits were injected 5% sodirm morrhumate through carotid artery unilaterlally. All specimens were examimined histochemically. Result A reduction in alcian(AB) blue staining was observed after operation, a gradual increase in AB staining with blood supply restoration of TMJ tissue was observed. Conclusion The result suggests that the decrease in blood supply of the temporomnandibular jorint leads to the loss of GAG in the condylar cartilage, which may play an important role in pathogenesis of osteoarthrosis.
