Objective:To analyze the pros and cons of the US strategic national stockpile ( SNS) from the per-spective of the supply chain and to put forward suitable recommendations for China’s national emergency medicine system. Methods:Literature review and a comprehensive analysis have been utilized to understand the SNS supply chain model and its differences from the Chinese model. Results:From the perspective of the supply chain, the Unit-ed State’s storage of emergency medicine consists of the forward placement of push packages, managed inventory and purchase contracts. The deployment of logistics for emergency medicine must gain approval from the federal government’s “local-state-nation” system, and be conducted at a different time. To transmit information, a large da-tabase, simulation software, and a technical advisory response unit have been established to manage information flow to distribute medicine accurately and promptly. Conclusion:Given the experiences of supply chain management in the US SNS system, it is critical for China to improve the supply chain system of emergency medicine, define the institu-tions and responsibilities within the supply chain, establish disaster relief reserve of emergency medicine and adopt fourth-party logistics for emergency medicine in order to make the China’s emergency preparedness more systemized, standardized, and information-based.

MethodsThe periphery blood samples were exacted from 8 patients of 4 generations of with congenital cataract in this family.The complete coding region and intron spliced sites of CRYAA,CRYAB,CRYA1/A3,CRYBB2,CRYGC and CRYGD were amplified with polymerase chain reaction (PCR),and the products of PCR were directly sequenced.The control blood samples were from 10 normal subjects.This study followed the Declaration of Helsinki.Written informed consent was obtained from all of the patients.ResultsThe patients were found in each generation in this family and the mode of inheritance was in accordance with the characteristic of autosomal dominant inheritance.The sequence of amplified genetic fragments of CRYAA,CRYAB,CRYA1/A3,CRYBB2,CRYGC and CRYGD genes were inaccordance with those of normal subjects and GeneBank.No any mutation loci was found in all of the patients of this family.ConclusionCRYAA,CRYAB,CRYA1/A3,CRYBB2,CRYGC and CRYGD genes is not the causing-disease genes in this family.

OBJECTIVE: To explore the diagnosis, treatment and surgical approaches of parapharyngeal space tumors. METHOD: This retrospective study consisted of 112 patients with parapharyngeal space tumors underwent surgeries. The data included clinical symptoms and signs, pathological types, imaging examinations, surgical approaches and postoperative complications. RESULT: Computerized tomography (CT), magnetic resonance imaging (MRD and digital subtraction angiography (DSA) made clear the tumor size, localization and its relation to adjacent structures. The postoperative histopathology varied and showed benign in 98 cases consisting of salivary gland tumors (52 cases), neurogenic tumors(33 cases) and other types (13 cases). During the 3 years follow-up period, local recurrence appeared in 3 patients with salivary pleomorphic adenoma and 1 patient with neurofibromatosis. These recurrent tumor cases were cured with second surgery. In 14 patients with malignant tumors reported, 8 cases survived for 5 years, 2 cases (1 adenoid cystic carcinoma and 1 carcinoma in pleornorphic adenoma) recurred in the two and a half years cured with second surgery affiliated radiation therapy through 3 years follow-up time and the rest were followed up 1 to 3 years without recurrence. Peripheral facial paralysis was observed in 25 patients, and 3 patients experienced hypoglossal nerve palsy. Only 1 patient encountered vagus nerve injury, and 2 patients appeared Horner's syndrome, and 4 patients endured Frey syndrome. Gills leakage was discovered in 3 cases and cavity infection was noted in 1 patient. CONCLUSION CT, MRI and DSA were important in the diagnosis and differential diagnosis of parapharyngeal space tumors. The key to successful treatment is knowing the anatomy of the parapharyngeal space, preoperative assessment and appropriate surgical approach.

Purpose To exp1ore the c1inicopatho1ogica1 features,diagnosis and differentia1 diagnosis of mu1ti1ocu1ar cystic rena1 ce11 carcinoma( MCRCC). Methods 18 cases of MCRCC were reported by microscopy,immunohistochemistry,differentia1 diagnosis and were fo11owed-up. Results A11 patients were adu1ts inc1uding twe1ve ma1es and six fema1es who aged from 26 to 68 years(mean 55. 6 years). Imaging studies revea1ed a po1ycystic mass,with c1ear boundary. Gross1y,the cut surface of the tumors had more cysts of va-rying sizes,containing serous or b1oody f1uid. Microscopica11y,the cyst wa11s of tumors were often covered with a few simp1e c1ear ce11s,stratified epithe1ium or devoid of epithe1ium. The septa contained aggregates of epithe1ia1 ce11s with transparent cytop1asm which showed gradeⅠ nuc1ear features,these characteristics were diagnostic c1ues of MCRCC. Immunohistochemica11y the c1ear ce11 was positive for CD10,vimentin,EMA and Ki-67 showed 1ow pro1iferative activity. 18 case were fo11owed up,mean fo11ow-up 43 months, no case recurred or with metastasis. Conclusion MCRCC is a rare histo1ogica1 subtype of rena1 ce11 carcinoma with more favorab1e prognosis. It shou1d be distinguished from cystic change of c1ear ce11 rena1 carcinoma and cysts of kidney 1esion.

Objective To discuss the cause and treatment strategy for open laryngotracheal trauma.Methods The clinical data of 38 cases with open laryngotracheal trauma admitted from 1998 to 2012 were collected and analyzed.Of them,one patient died in emergency department despite energetic resuscitation,37 were hospitalized and given advanced treatment after life support measures in emergency department.They were treated with tracheotomy before or during operation.Of them,32 patients were regularly followed up for imaging studies.Result Except 1 patient died of exsanguination from carotid artery rupture,the other 37 survived after successful treatment.Twenty patients were treated with debridement and suture of the wounds and laryngoplasty (20/37,54.1％),8 patients were operated with laryngoplasty plus intraluminal stents implanted (8/37,21.6％) ; the rest 9 patients (9/37,24.3％) were separately given placement of nickel-titanium shape memory alloy stent (n =2),laryngofissure with rubber gloves throat models implanted and laryngoplasty (n =3),linear silicone tube implanted and laryngoplasty with trans-cervical approach (n =1) and tracheoesophageal fistula neoplasty with laryngoplasty and laryngofissure (n =3).The operated patients were followed-up for 0.5 to 3 years after discharge.Of them,35 patients (35/37,94.6％) had successful decannulation,breathing smoothly and swallowing normally,23 patients (23/37,62.2％) had almost normal pronunciation,12 patients (12/37,32.4％) had different degrees in hoarseness of voice,and 2 patients (2/37,5.4％) were referred to other hospital because of failure in extubation with severe stenosis of laryngotrachea.Conclusions When the patients with open laryngotracheal trauma were treated,the essential strategy was to prevent shock,hemorrhage,and asphyxia.In the case of patent respiratory tract and stable vital signs,laryngotracheal reconstruction should be carried out as soon as possible to prevent complications,thereby obtaining good therapeutic effect.
