The conductive education system in Hong Kong is considered to be suitable to the rehabilitation work for children with disabilities, with the philosophy of person-based, respecting the children personality and their development needs. The system integrates the international conductive education into local rehabilitation, and creates education-rehabilitation system adopting Hong Kong conditions. Through this system many children with disabilities are improving their ability of adopting society, which is a good foundation for them to their social inclusion. Their experiences are worth to learn and reference by rehabilitation institutes and workers in mainland China.

Objective To investigate the regularity of thoraco-abdominal two-field lymphatic metastasis and methods of the nodal dissection in middle-third thoracic esophageal carcinoma,and to guide the scope of the lymph-node clearance.Methods Thoraco-abdominal two-field lymph-node dissection based on surgical incisions of the right chest and middle upper abdomen were conducted in 62 cases with middle-third thoracic esophageal cancer and the regularity of nodal metastasis was analyzed.Results Five hundred and five pieces of lymph node were cleaned in all 62 patients and among them 102 pieces were detected as metastasis lymph node,the nodal metastasis ratio was 20.2％ (102/505).The middle-third thoracic esophageal cancer not only includes the nodal metastases up to the trachea of the right neck,around the bilateral recurrent laryngeal nerve chains,near the esophagus and the tumor,and the lymph-node metastasis at the inferior tracheal protuberance,but also the nodal metastases down to the cardiac,around the left gastric artery and at the retina of the lesser curvature of the stomach etc,presenting a tendency of 2-way metastasis.The infiltration depth and differentiation of the tumor is of statistical significance on the nodal metastasis ratio.There was significant difference on the metastasis rate of lymph node from T1 to T4 (T1:10.0％ (1/10),T2:20.0％ (3/15),T3:43.3 ％ (13/30),T4:57.1％ (4/7),x2 =18.56,P ＜ 0.05).It indicated that metastasis rate was increased with the development of the infiltration depth.There was significant difference on the metastasis rate of high differentiation carcinoma,moderate differentiation carcinoma and low differentiation carcinoma (14.3％ (2/14) vs 39.5％ (15/38) vs 57.1％(4/7),x2 =17.75,P ＜ 0.05).Conclusion The lymph node metastasis of patients with middle-third thoracic esophageal carcinoma is significantly correlated with the depth of tumor invasion and the degree of differentiation,with the tendency of thoraco-abdominal 2-field nodal metastasis.The peritracheal lymph node at right neck and bilateral recurrent laryngeal nerve chains are important regions of the metastasis.The surgical incision of the right thorax and upper abdomen greatly facilitates the excision of the middle-third thoracic esophageal cancer and the 2-field lymph node dissection Thus on this basis,the lymph node clearance around the right trachea and at bilateral recurrent laryngeal nerve chains through the right thoracic apex is safe and feasible.

本文根据汶川地震伤员救治工作取得的阶段成果,针对部分伤员可能造成的伤残问题,从康复工作的组织管理角度,探讨采取积极的康复措施,使伤员尽早通过早期康复干预、系统康复训练、社区家庭康复,最大限度地恢复和改善功能,达到生活自理,回归家庭和社会的目标。

Problem-based social practice is organically combined with health education lessons,to improve tobacco control capacity of preventive medicine students,through study in class and social practice after class.The students' awareness rate of tobacco regulations,support rate of smoke-free school,rejecting smoking rate,and lifetime non-smokers rate have significantly increased ( 40％～90％ ) after intervention.The teaching method is adult learning model,and it has effectively enhanced preventive medical students' tobacco control capacity.

bnormality in these parameters was improved.

Objective To compare the safety and effectiveness of power peripherally inserted central catheters (Power PICC) and double cavity central venous catheter (CVC) application in intensive care unit (ICU). Methods 458 cases were reviewed during January to September in 2014 and divided into two groups: Power PICC group (245 cases) and CVC group (213 cases) , and average retention time, successful rate of inserting catheter and the incidence of complications were compared. Results The average retention time of Power PICC group was (21.6±5.8) days which was longer than (13.1±3.4) days of CVC group (t=2.234, P <0.05). No statistics difference of successful rate between two groups (P>0.05). No significant difference for the total incidence of complications between two groups as 14.69% (36/245) and 19.72%(42/213)(P>0.05). No significant difference for the total incidence of complications in the operation time between two groups as 5.31% (13/245) and 4.23% (9/213)(P>0.05). But rate of catheter malposition for Power PICC group [ 2.86% (7/245) ] was higher than CVC group 0 (X2=4.428, P <0.05). Rate of the total incidence of complications in the retention time Power PICC group [ 9.39%(23/245) ] was lower than CVC group [ 15.96%(33/213)(P<0.05). And rate of catheter related blood stream infection of CVC group [3.29%(7/213)] was much more higher than Power PICC group (0)(X2=6.139,P<0.05). Conclusions Power PICC and CVC are both applicable for ICU, and Power PICC has more advantage regarding safety and effectiveness than CVC and can be one replacement for CVC.

Objective To discuss the diagnostic value of 3D-ultrasound for cord entanglement in monoam-niotic twins. Methods From November 2013 to March 2016,a total of 65 monoamniotic twinsunderwent routine obstetric ultrasonography to screen fetal abnormalities in our hospital. The cord was meticulously observedusing a systematic continuous sequence approach. Fetuses who showed cord entanglement by 2-D ultrasound or 3-D flow Doppler were all recruited. The gestational weeks,fetal malformation,ultrasonic image feature of cord entangle-ment,and clinicaloutcome were recorded and analyzed retrospectively. Results 4 monoamniotic twins showed cord entanglement. Three-dimensional color Doppler clearly delineated thefeatures of entanglement. At following-up of 8 fetuses,3 fetuses were found intrauterine fetal death and 3 fetuses with structural abnormalities except for 2 well infants.Conclusion Cord entanglement may threaten the safety of fetusesin monoamniotic pregnancies.In aid of 2-D ultrasound or 3-D flow Doppler in monoamniotic twins can help to find it in time ,monitor it carefully and provide evidence for obstetric treatment .
