Objective To seek a operation method of quality control of biochemical tests in peacekeeping mission via perspective of evidence-based laboratory medicine .Methods Literatures related to quality control of biochemical tests in international peace-keeping were referred ,compared and discriminated .Combined with 5-year peacekeeping laboratory experience ,a set of feasible ap-proaches were worked out and a practice evaluation was performed in a task period .Results Under the supervision of the quality control system ,providing accurate and reliable test results to the clinical ,developing and implementing quality control of biochemical tests were economical ,practical and reliable ,and could guarantee the effectiveness of reports of biochemical test in peacekeeping medical institutions .Conclusion Evidence-based laboratory medicine is important for quality control of biochemical tests in peace-keeping medical institutions .

Objective To discuss the clinical preventation and treatment of the complications induced by endotracheal intubation in SICU.Methods Retrospective analysis was used on 55 cases of intubated patients in our hospital nearly 2 years.Results The incidence of endotracheal intubation was 36.4％,pneumonia 23.6％,accidental extubation 5.5％,endotracheal ulcer 1.8％,tracheoesophageal fistula 1.8％,obstruction of tracheal catheter 1.8％,arytenoid dislocation 1.8％.Conclusion The causeof complications of endotracheal intubation in SICU were overtime intubation,tranma,excessive-pressure of the air cuff and local inflammation.Airway humidification,suitable sedation,accurate and moderate operation,extubation or tracheotomy,suitable cuff pressure and fiberoptic bronchoscopy examination could avoid such complications.

Objective: To study the influence of screening dementia with mini-mental state examination (MMSE) combining with delay memory test . Methods: MMSE and delay memory test are used in screening 301 residents. The diagnosis of dementia is according to the DSM-Ⅲ-R criterion. The validity and reliability were studied when the MMSE and delay memory test were used to screen dementia alone or combined. Results: When MMSE was used to screen dementia alone, the specificity, sensitivity, false positive proportion and false negative proportion were 85.40%, 52.43%, 47.56% and 14.60% respectively. When delay memory test was used to screen dementia alone, the specificity, sensitivity, false positive proportion and false negative proportion were 74.45%, 92.07%, 7.93% and 25.55% respectively. If parallel connection of MMSE and delay memory test were used to screen dementia, the specificity, sensitivity, false positive proportion and false negative proportion were 95.62%, 49.39%, 50.61% and 4.38% respectively. If MMSE was in series with delay memory test, the specificity, sensitivity, false positive proportion and false negative proportion of screening dementia were 64.23%, 95.73%, 4.27% and 35.77% respectively. Conclusion: The parallel connection of MMSE and delay memory test can elevate sensitivity of screening dementia and decrease false negative proportion, so it is important in epidemiologic investigation. MMSE in series with delay memory test will raise specificity of screening dementia and decrease false positive proportion, so it is useful for diagnosing early dementia.

Ribosome-inactivating proteins(RIPs), a natural anti-caner protein from some advanced plants, includes single-chain robosome-inactivating proteins (type Ⅰ) and double-chain ribosome-inactivating proteins (type Ⅱ). Gelonin, relative molecular weight around 30?103, belongs to single-chain ribosome-inactivating proteins. This review is about the structure and biological activity of cell toxin Gelonin and application prospect in anti-cancer treatment.

[Objective]To summary wound related complications and risk factors of sacral tumor surgery,and discuss the prevention and treatment strategy in order to decrease surgical risk and prevent the related complications.[Methods]From August 1997 to June 2008,302 patients with sacral tumors who underwent operations were retrospective studied to review complication types,risk factors and treatment strategies of complications.[Results]Wound nonunion,deep infection,cerebrospinal fluid leakage,viscera injuries and severe bleeding were the most common complications of peri-operation stage.Tumor diameters larger than 10cm,surgery and radiation history were the major risk factors of wound nonunion,deep infection and viscera injuries.Severe bleeding happened in 11 patients,and the major risk factors were tumor larger than 10cm,tumor locating at S2 or higher and en bloc surgery.Surgery and radiation history were the main reasons of cerebrospinal fluid leakage.[Conclusion]Understanding the risk factors of complications of sacral tumor surgery are helpful to judge and prevent complications after surgery.Some measures of prevention and treatment are effective to decrease the surgical risks.

[Objective]To retrospectively study all the low grade central osteosarcoma(LGCO) cases treated in our center in about a past decade.[Method]Thirteen cases with LGCO treated from January 1998 to June 2008 were studied.The mean age at diagnosis was 31-year-old.The anatomical location of the lesions was similar to that of a conventional osteosarcoma.Pain and mass were common complaints with a mean duration of 16 months before diagnosis.Eight cases accepted the first operation in our center,while the other 5 cases had undergone operations in other hospitals with an intralesional resection in four and a marginal resection in one.Eleven patients had an Enneking stage I disease and two had a stage III disease.The first choice for patients with stage I disease was wide resection.[Result]In two patients with local recurrence,the postoperative pathological diagnoses were fibrosarcoma and malignant fibrous histocytoma respectively.The metastatic lesions were found to be a LGCO in both patients with stage III disease.The average follow up duration was 29 months.Lung metastasis occurred in one stage I patient 15 months after operation.Gama-knife was used to get rid of the lung lesions and then systemic chemotherapy was given.Now he was still alive with disease 27 months after the first operation.One of the 2 patients with stage III disease died of the disease 26 months after operation and the other one was failed to follow up 6 months after operation.The other 10 patients were alive without disease at the last follow-up.For those who received limb salvage operations,the mean MSTS 93 score was 79%.[Conclusion]For most patients with LGCO,wide resection of tumor is preferred.Good oncologic and functional results could be expected after a limb salvage operation without chemotherapy.Insufficient resection of tumor would lead to recurrence.Long time follow up is compulsory.High grade sarcomas would be found in some of the local recurrent lesions.Metastasis would occur in few patients and the metastatic lesions may still be a LGCO.

Objective To construct a novel VP 1 gene vaccine against coxsackievirus B 2 and to evaluate the effect of the cell-mediated immunity induced by it.Methods The immunodominant capsid protein VP 1 gene of CVB 2 was amplified by reverse transcript polymerase chain reaction (RT-PCR) and pcDNA 3-CVB 2VP 1was constructed by molecular cloning.The cytotoxic T lymphocyte (CTL) activity was measured by standard 51Cr-release cytotoxicity assay eight weeks after BALB/c mice were immuned by pcDNA 3-CVB 2VP 1.Results The eukaryotic expression vector was pcDNA 3 and subcloning fragment was CVB 2VP 1.The CTL activity of pcDNA 3-CVB 2VP 1 group was higher than that of the control (P
