Objective To discuss the features and surgical management of ectopic hyperparathyroidism.Methods Clinical data of 66 cases of ectopic hyperparathyroidism were retrospectively analyzed.Results There were 66 cases of ectopic hyperparathyroidism accounting for 11.5％ (66/575) of all ectopic hyperparathyroid cases admitted during the period from 1982-2010.Prevalence of mediastinal ectopic lesions was 71.2％ (47/66),among those 65.2％ (42/66) was in anterosuperior mediastinum,and 28.8％ (19/66) in the non-typical loci of the neck.Radionuclide imaging of parathyroid glands was the most sensitive (87.0％) method among all common positioning examinations.Average number of operation episode was 1.47,and all lesions were finally resected.After surgery 49 cases presented with transient hypocalcemia,and were cured by calcium administration.52 cases were followed up,with recurrent hyperparathyroidism in 1 case.Conclusions Diagnosis and treatment of ectopic hyperparathyroidism are dependent on the understanding of common locations of ectopic parathyroid glands.Preoperative correct location and surgical expertise are helpful for successful resection.

Adrenergic receptors are members of the G-protein coupled receptor superfamily. Recent studies revealed that these adrenergic receptors are playing an important role in the growth and metastasis of prostate cancer cells. The expression of adrenergic receptors rises significantly in prostate cancer cells and tissues. Agonists of these receptors promote the growth and mobility of prostate cancer cells, while antagonists may suppress their proliferation, trigger their apoptosis, and inhibit their metastasis. Clinically, receptor antagonists can significantly reduce the risk of prostate cancer and improve its prognosis after androgen depravation therapy. This article presents an overview on the roles of adrenergic receptors in prostate cancer.

Objective To perform facial nerve monitoring in patients under the low level of neuromuscular blockade during resection of acoustic neurinomas.Methods Twenty-eight patients with large,or medium acoustic neuroma underwent the surgery of acoustic neurinomas resection. During the operation,TOF and EEG monitoring were performed in order to detect the degree of muscle relaxation and the depth of anesthesia. Neuromuscular relaxation was maintained at T_4/T_1=25%～50% by adjusting doses of muscle relaxant and aneasthetic. Free-run EMG and Triggered EMG of orbicularis oris, orbicularis oculi, masseter and trapezius were recordered to monitor the function of the facial, trigeminal and accessory nerves, respectively. The function of the facial nerve was evaluated at first week and half year postoperatively according to House-brackmann classification.Results The facial never was successfully identified and mapped by neurominitoring in all 28 patients. successfully, tThe electrical stimulation was 0.1 mA-0.3 mA and no any involuntary body movement was observed in all patients ne of patients have moved during operation. The preservation of the facial nerve function following surgery was good. Five patients had a HB grade I, 13 a HB grade II, 8 a grade III and 2 a HB grade IV The facial nerve function was HB Grade Ⅰin 5 of 28 patients, HB GradeⅡ in 13, HB Grade Ⅲ in 8 and HB Grade Ⅳ in 2 immediately after operation. Six months after surgery, 10 casespatents showed demonstrated a HB GradeⅠof facial never function, 12 cases exhibited a slight palsy (HB Grade II) , and 5 cases exhibited a HB Grade III palsy and . Another 1 cases a exhibited severe palsy (HB Grade IV).Conclusions Facial nerve monitoring in patients under the low level of neuromuscular blockade can ensure the surgical safety and preserve the facial never function.

Abstract? AIM: To evaluate the efficiency of two different operation ways, vitrectomy and vitrectomy combined with inferior scleral buckling, for a complex kind of retinal detachment.?METHODS:The complex kind of retinal detachment were diagnosed in 100 cases ( 100 eyes ) , with the common features:1)the course of more than 1mo;2) at least one retinal hole located in the inferior marginal retina;3) the detachment of retina was found proliferated, there was at least 1 retinal fold in retinal detachment area. The patients were randomly divided into two groups: the treatment group ( 50 eyes ) who received vitrectomy combined with inferior scleral buckling;the control group ( 50 eyes ) who received vitrectomy without scleral buckling. The retinal anatomic reattachment, visual function recovery, macular central fovea thickness and complications in two groups were observed.? RESULTS: There were 49 eyes ( 98%) with retinal anatomic reattachment in the treatment group while 42 eyes(84%)in control group(χ2=4.2605, P<0.05);the best corrected visual acuity ( BCVA) was 0.254 ±0.238 in the treatment group while it was 0.219±0.229 in control group (t=1.8879,P>0.05);the macular central fovea thickness was 272 ±32.21μm in the treat group while it was 316 ± 33.46μm(t=12.597,P<0.01).Intraocular pressure in 12 eyes ( 24%) was more than 30mmHg in the treatment group while 4 eyes ( 8%) in control group within 1wk postoperation (χ2=4.7619,P<0.05); intraocular pressure in 100 eyes were controlled below 21mmHg 1mo postoperatively.? CONCLUSION: It is a more effective method to vitrectomy combined with inferior scleral buckling than the single vitrectomy for the special kind of retinal detachment.It can increase the rate of retinal anatomic reattachment and reduce macular edema.

Objective To analyze the clinical features and the application of bronchoscopy in diagnosis and treatment of children with bronchiectasis.Methods All cases with bronchiectasis were collected from in-patient department of the Children's Hospital Affiliated to Nanjing Medical University from December 2011 to November 2015.Clinical manifestations,results of bronchoscopy examination were retrospectively analyzed.Results Of the 33 children,32 cases (97.0％) had chronic cough and sputum.Lung infection was the main cause (50％,16/33 cases).High resolution CT showed signet ring sign and/or double-track sign in lungs,and bronchiectatic lesions were most commonly found in the lower lobes (60.6％).Eighteen cases underwent bronchoscope ciliary biopsy,and the number of cilia decrease was found in 2 cases,and cilia ultrastructure abnormalities were found in 6 cases,with 2 cases diagnosed as Kartagener syndrome.The treatment included the following:treatment of the underlying disease,aggressive treatment of infections,promotion of mucociliary clearance,and bronchoscopy.The symptoms of the most patients were relieved through the symptomatic treatment.Follow-ups after discharge,showed that 15 cases had a slight cough without obvious sputum,11 cases with recurrent lung infections,regular bronchoscope lavage treatment;4 cases underwent surgical lung resection and recovered well postoperative,and 2 cases died.Conclusion The bronchoscopy should be performed early in the children with bronchiectasis,which can clearly detect pathogens and causes,so as to undertake lavage treatment to improve clinical symptoms.
