ABSTRACT
Cervical cancer is an important global public health problem,and its incidence tends to be younger in China.Compared with stage ⅡB cervical cancer,concurrent chemoradiotherapy has obvious advantages in reducing local recurrence rate,improving progression free survival rate,overall survival rate,and improving prognosis.Concurrent chemoradiotherapy and surgical treatment can effectively reduce local lesions and increase the opportunity for surgical resection.Synchronous radiotherapy and chemotherapy do not increase the difficulty of operation and postoperative complications.At the same time,all kinds of short-term and long-term complications caused by radical radiotherapy are avoided.The new adjuvant chemotherapy will strive for radical surgery,using radical surgery to eliminate the focus of radiotherapy and chemotherapy,improve the patient's survival time and improve the patient's quality of life.Preoperative radiotherapy can also maintain the physiological function of the vagina and avoid various complications caused by the amount of radical radiotherapy.
ABSTRACT
Local and/or regional recurrence is a common cause of the failure of primary radical radiotherapy for nasopharyn-geal carcinoma,and it is also a clinically existing treatment problem. Re-radiation therapy is one of main effective means of treatment for recurrent nasopharyngeal carcinoma. The article summarizes the recent domestic and abroad literatures on radiotherapy in vitro(in-cluding conventional two-dimensional,three-dimensional conformal,intensity-modulated radiotherapy),stereotactic radiotherapy, brachytherapy,proton beam and heavy ion therapy for recurrent nasopharyngeal carcinoma,and summarized the advantages and disad-vantages of different radiotherapies as well as their efficacies.
ABSTRACT
Objective To evaluate whether the comparability of 3 automatic blood cell analyzers meet the clinical requirements by conducting the comparative study on the detection results of these instruments.Methods With the Sysmex 2100 automatic blood cell analyzer as the reference instrument,Sysmex 1000i and Abbott 1800 as the experimental instrument,the original quality control provided by the instrument factory and the patient′s fresh anticoagulant blood samples in the laboratory were adopted to monitor for continuous 40 d by these three instruments and the detection results of WBC,RBC,HGB,HCT and PLT were analyzed.Results The detection results of these 3 instruments were statistically tested by the F test,the differences showed no statistical significance (P >0.05)and the bias was in 1/2 of the maximum permissible error range in America department clinical test revised regulations (CLIA′88).Conclusion The detection results by these 3 instruments are comparable and can meet the clinical requirements.
ABSTRACT
Objective To provide the scientific basis for realizing the inter-accreditation of laboratory electrolyte detection results by comparing the electrolyte detection results in 5 grade 3A hospitals of Zhuhai city .Methods Each 10 serum samples with low , middle and high concentrations of electrolyte were collected for simultaneously detecting the electrolyte kalium (K) ,natrium (Na) and chlorinum (Cl) .The detection results were performed the statistical analysis and comparison .The mutual bias within 1/2 of al-lowable error of CLIA′88 indicated that the detection results were mutually accredited ,if the mutual bias exceeding 1/2 of allowable error ,the detection results could not be mutually accredited .Results The difference of electrolyte detection results in 5 hospitals accorded with the stipulation requirement of CLIA′88 .Conclusion The electrolyte detection results of 5 hospitals could be mutually accredited .
ABSTRACT
Objective To establish a multiple PCR method that can be used to spontaneously detect five kinds ofpathogens such as NG,MH,MG,CT and UU.Method With the fluorescence-quantitative PCR technique in conjunction with another detection technique as the golden standard,evaluation was conducted on the sensitivity,specificity,accuracy and repeatability on the detection of 5 kinds of STD pathogens using single-tube multiplex PCR.Result The sensitivity,specificity and match rate of the method ale 10-9fg/μl,100%,97.8%respectively,and the repeatability of 5 continuous days of 20 clinical specimens is good.Conclusion Single-tube multiplex PCR technique provides a new method to detect 5 kinds of STD pathogens.
ABSTRACT
The way to develop the seven-year program studnts'ability mainly includes:paying great attention to study the basic theory for developing students'comprehensive abilities;laying stress on clinical teachers'important role in training students'ability on scientific research and their participation in clinical scientific research activities in order to develop their ideology and ability of clinical oncology scientific research.
ABSTRACT
Objective:To study the treatment result of the unresectable advanced pancreatic cancer by radiotherapy. Methods: A total of 16 patients with unresectable advanced pancreatic cancer were treated by radiotherapy from March 1996 to December 2001. According to TNM staging system, there are 5 patients in stage II, 6 in stage Ⅲ and 5 in stage Ⅳ. Karnofsky score were ranged from 30～70. Eight patients were treated by the conventional fractionation (1.8～2.0 cGy/f, 5f/w), and eight patients treated by non-conventional fractionation(1.2～1.8Gy/f,2～3f/d).The radiation dose was70Gy for 3 cases. Results:The remission rate was 85.7 percent. The median survival course was 9.2 months(3～30months). 1-year survival rate was 31.25 percent. The pretreatment performance status and TNM stage were important prognostic factors. Both groups of Karnofsky score 60～70 and stageⅡ,Ⅲ showed a highly significantsurvival improvement when compared with groups of Karnofsky score 30～50and stage IV ( P
