Objective To i nv estigate the clinical effect of shape-memory sawtooth-arm em bracing fixator in the management of periprosthetic femoral fracture.Methods Since1994, 21cases of periprosthet-ic femoral fractures had been treated in7hospitals with the shape-memory sawtooth-arm embracing fixator designed and developed b y the Ninth Peoples Hospital,Shanghai Second Medical University(SSMU ).Of the21cases,12were males and9were females,aging from42to83years old. Eighteen of the series ex peri-enced periprosthetic fracture at2weeks to10y ears after joint replacement the fractures were found as oblique,spi ral or comminuted with the fracture lines located between the lesser trochanter and a p oint 5cm distal to the end of prosthetic stem.The other three were revision c ases,in which2cases with osteoporosis had intraoperative spiral fracture and1 case had long segmental osteotomy for removal of the prostheses.One of the 21patients had Z-shaped femoral osteotomy,while the other20cases were clas sified into Jo hannson typeⅠfrac ture in4cases,typeⅡ9cases and typeⅢ7case s.All of them were complete fracture with dis-placement.In practice,the arm s of fixator were expanded firstly by immersing into the ice water to make the tempera ture of the device decrease to4~7℃.After reduction of the fracture ,the body of the fixator was placed on the tensile side of the femur,and th e temperature of the arms was raised with hot saline.With its shape memory ef fect,the sawtooth-arms began to close up and grasped the fracture fragments ti ghtly.Results Surgical process in all of the cases was smoothly done:the frac tures were stable after the fixation,and no ex-ternal fixation was required po stoperatively,except four cases underwent skin traction of the affected lim b for 2weeks.All the patients were able to walk with two crutches at2to4we eks after the operation.The post-operative follow-up lasted from1to7years, and no fracture re-displacement was found.The results of frac-ture healing were good while the functional recovery to the pre-operative level was achieved in the all se ries.Conclusion For periprosthetic femoral fracture,shape memo ry sawtooth-arm embracing fixator is a re liable device being implanted easily and offering stable fixation;it should be the treatment method of the first choice.

For pharmaceutical industries, clinical data is one of the most valuable deliverables. It is also the basis of analysis, submission, approval, labeling and marketing of a drug product. To ensure the integrity and reliability of clinical data, a scientific standardized quality control (QC) has to be established at each step of a clinical trial. Data validation is conducted to ensure the reasonability and compliance of clinical data by checking data quality before the data is statistically analyzed. This paper focuses on purpose of data validation, creation of data validation plan, rationale of data validation, types of data validation and performance of user acceptance testing on clinical database.

Objective To evaluate the levels of serum organochlorine pesticide residues in breast cancer patients and benign breast disease patients from Tangshan areas. Methods One hundred fifty-eight breast cancer patients and 129 benign breast disease patients from two districts of TangShan were entrolled in the study. The levels of serum organochlorine pesticides ( DDTs and HCHs) were detected through gas chromatography/electron capture. Spearman's rank correlation was used between age, BMI and the level of serum organochlorine pesticide residues in patients. Results The serum levels of a-HCH, p-HCH and PP'-DDE between breast cancer patients and benign breast disease patients were statistically different(P <0. 05). The serum levels of p-HCH and PP'-DDE were positively correlated with age and BMI in both groups, with correlation coefficients of 0. 272 and 0. 330 for age and 0. 207 and 0. 313 for BMI in the breast cancer patients,as well as correltion coefficients of 0. 339 and 0. 260 for age and 0. 227 and 0. 209 for BMI in the benign breast disease patients. Conclusions The levels of organochlorine pesticide residues in serum in breast cancer patients were higher than those in benign breast disease patients and were positively correlated with age and BMI. The results offer more information to the pathogenesis, prevention and control measures of breast cancer.

Objective To study the therapeutic effects of conservation surgery of laryngeal function for larygeal carcinoma in patients aged 70 years and over. Methods 136 patients aged 70 years and over were collected. Among them, 34 cases underwent vocal cord resection, 28 vertical hemilaryngectomy, 24 horizontal supraglottic hemilaryngectomy, 15 horizontovertical (3/4)laryngectomy, 29 subtotal laryngectomy, 6 total laryngectomy with cricopharyngeal anastomosis.Tissue defects were repaired by use of cervical myocutaneous flap in patients of T3-4 tumor stage. After operation, a special pneumatoeeles was attached on the tracheal cannula when eating.Results All patients had their phonation restored in a week. 92 cases were decannulated. 45 cases had cough and then were improved after respiration training and one case was in failure. No death occurred in the perioperative period. The survival rates were 78.7% at 3 years and 68.5% at 5 years.Conclusions Laryngectomy with reservation of laryngeal function is feasible in senile patients aged 70 years and over under conditions of correct indication, right choice of operation and thoroughly care during perioperative.

Objective To explore the clinical effect of small cell lung cancer(SCLC) treatment with recombinant human endostatin injection and cis-platinum complexes.Methods 100 patients with SCLC were divided into 2groups.The experiment group used cis-platinum complexes while the control group used recombinant human endostatin injection.Results The effective rate of experiment group was obviously higher than the control group ( 74.0％ vs60.0％,x2=2.16,P ＜ 0.05 ).The median survival time of experiment group was better than control group( t=2.02,P ＜ 0.05 ).The diverse of untoward effect of two groups had no difference ( P ＞ 0.05).Conclusion Recombinant human endostatin injection and cis-platinum complexes were better therapy for SCLC,which had stable effect,no severe untoward effect and overcome the drug-fast of cis-platinum complexes.

Self-designed experiments were used to study the effects on developing the students'ability and improving teaching quality.The results show that self-designed experiments can improve students'learning interest, motivation,coordination,and research capabilities.

To explore the value of local anesthesia under ultrasonic guidance for establishing puncture path of superficial tumor.A total of 144 patients with superficial tumor received local pre-puncture anesthesia under ultrasonic guidance so that all lesions were targeted.Transient aggregation of narcotics was applied for raised (n =12) or superficial (n =15) skin lesions.The clarity of scanning acoustic window was enhanced,the puncture distance of tumor broadened and the mass of axial changed to obtain a longer lymph node cortex.The damage of blood vessels occurred easily due to tumor closeness to large blood vessel or shortened puncture path in 17 cases.Anesthetic drug was injected between tumor and blood vessels to enlarge the thickness for visualizing the puncture needle tract clearly.And puncture was accomplished under the guidance of color Doppler.Therefore a puncture path can be created effectively with local anesthesia by ultrasonic guidance.
