Acromegaly is mostly caused by a pituitary adenoma secreting growth hormone ( GH ) , which leads to a wide range of endocrine morbidities, with an insidious onset and slow progression.A long-term overproduction of GH results in elevated insulin-like growth factor-1 ( IGF-1 ) level, which in turn, would cause target organ damage and an increased risk for mortality and decreased quality of life.Herein, the literature regarding the progress of drug therapy for acromegaly in recent five years is reviewed.

Objective This study aims to study the characteristics of intonation pronunciation in preschool children with hearing impairments .Methods A total of 30 of 4~5 years old children with hearing impairment and 30 of 4~5 years old children with normal hearing were enrolled in this study .With statement intonation and ques-tion intonation as test material ,the compartment between the children in two groups were obtained .Results Pre-school children were generally increased the ending point and slope to distinguish statement intonation .There were still differences between hearing -impaired children and normal children .Under statement intonation condition :the children with hearing impairments showed a significantly lower level of the slope of the high and level boundary tone than the normal children ,the starting point and the ending point of the falling boundary tone in hearing -impaired children were significantly lower than those of in normal children ;Meanwhile ,under question intonation condition :com-pared with normal children ,the slope of the high and level boundary tone ,the rising boundary tone and the falling -rising boundary tone in hearing -impaired children were significantly lower .The starting point ,the ending point ,the high and level boundary tone ,and the falling boundary tone in hearing -impaired children were significantly lower .Conclusion To implement targeted therapy during question intonation training for hearing -impaired children ,the acoustics characteristics of boundary tone are required to assess and monitor the effectiveness of rehabilitation .

Objective To evaluate the effect of mild hypothermia on the recovery from cisatracurium blockade during the recovery from anesthesia in patients .Methods Thirty ASA physical status Ⅰ or Ⅱ patients , aged 18-64 yr , with body mass index 18-25 kg/m2 , scheduled for elective abdominal surgery under general anesthesia ,were enrolled in the study .The patients were divided into 2 groups according to the body temperature recorded when cisatracurium infusion was stopped at the end of surgery .The body temperature 36.0-36.9 ℃served as normothermia group (group N , n=14 ) and 34.0-35.9 ℃ served as mild hypothermia group (group H , n= 16 ) . The body temperature was measured by a thermocouple placed in the nasopharynx . Neuromuscular function was monitored by measuring the evoked mechanical response of the adductor pollicis muscle to supramaximal train-of-four (TOF) stimulation (frequency 2 Hz ,wave length 0.2 ms ,intensity 50 mA ,interval 15 s) of the ulnar nerve at the wrist using TOF-Watch SX? .Cisatracurium was intravenously infused at 1-3μg·kg-1 ·min-1 during surgery to maintain neuromuscular block with 1%

Aim To investigate the effects of CP1 54526,a corticotropin releasing hormone (CRH) receptor 1 antagonist,on the hippocampal neuron ap-optosis.Methods Rat hippocampal neurons were primarily cultured.Cell viability was estimated using MTT assays.Neurons were randomly divided into four groups:Normal cultures (Control);CRH-exposed cul-tures (CRH);CRH and CP1 54526 co-exposed cul-tures (CRH + CP ); CP1 54526-exposed cultures (CP).Cell apoptosis was examined by TUNEL or flow cytometry Annexin Ⅴ-PI staining.The protein levels of Bax,Bcl-2 and Caspase-3 were investigated by West-ern Blotting.Results 1 0 -8 mol·L -1 CRH decreased cell viability of cultured hippocampal neuron (P <0.05),while 50 mmol ·L -1 CP1 54526 significantly increased neuron viability (P <0.05).Compared with Control group,cell apoptotic rate,the ratio of Bax and Bcl-2 and the protein level of Caspase-3 were elevated in hippocampal neuron induced by CRH.Combined with CP1 54526 reversed the effects of CRH.Applica-tion of CP1 54526 alone had no obvious effects on cell apoptosis.Conclusions A certain concentration of CRH can induce hippocampal neuron apoptosis,and its receptor 1 antagonist CP1 54526 can effectively re-duce the apoptosis and play a neuroprotective role.

The experiment was conducted at the Basic Laboratory of Integrated Traditional Chinese and Western Medicine, Chengdu University of TCM from March 2005 to March 2006. A total of 40 BALB/C male mice aged 6-8 weeks were selected, and randomly assigned into 4 groups: bcl-2 control group, bcl-2 experimental group, cmy-c control group and cmy-c experimental group with 10 in each group. From the first day of experiment, all the mice were treated with 5 g/L cyclophosphamide solution by intraperitoneal injection for successively 5 days, 6 mL/kg per day. From days 11 to 12, the mice in the bcl-2 experimental group and cmy-c experimental group received Danggui buxue tang by gastric perfusion, 6 mL/kg per day for 10 days. The mice in the control group received saline of the same volume. At day 20, all the mice were killed to obtain bone marrow cells of one side femoral bone of mice. The smear received bcl-2 in situ hybridization immunohistochemical staining after centrifugalization and washing in the bcl-2 control and bcl-2 experimental group. The smear received cmy-c in situ hybridization immunohistochemical staining after centrifugalization and washing in the cmy-c control and cmy-c experimental group.

Compared with the bcl-2 control group, there was significant difference (P

Epidermnoid cysts are henign, cutaneous cysts which commonly occur on face, neck and trunk. Retroauricular epidermoid cyst is rare reported which should be differentiated from auricle pseudocyst, lipoma, steatocystoma and fibroma. The hitopathological examination is a gold standard of diagnosis. Surgery of complete excision is the first choice of treatment methods.
