Mucopolysaccharidosis type Ⅱ is a rare single gene inherited disorder. In the earlier studies, more attention was paid to the molecular analysis of the hot spots of the mutations. With the detection of more and more novel mutations,more studies are trying to analyze the effect on splicing of different types of mutations and the genotype-phenotype correlations. This review will introduce the progress on molecular genetics, the gene mutation,analysis of the female patients and the genotype-phenotype correlations. With the study of these progress,it suggested that more attention should be paid to the possibility of gene-pseudogen recombinations, trying to study the effect on splicing from the cDNA level, which will benefit the investigation of the genotype-phenotype correlations.

Colorectal cancer is one of the most common malignancies in the world, and rectal cancer accounts for a large percentage of this disease in Chinese patients. Surgical extirpation is the mainstay of therapy, Intraluminal ultrasound is highly accurate in detecting depth of invasion and lymph node metastasis, and is also helpful in preoperative staging of rectal cancer. Preoperative adjuvant therapy could down-stage tumors, improve the radical resection rates of advanced lower rectal cancer, increase the rate of sphincter-saving surgery, and decrease the local recurrence rate. Total mesorectal excision could signifi-candy decrease the local metastasis of rectal cancer, and rectal cancer resection with preservation of pelvic autonomic nerve is effective in preventing urinary or reproductive dysfunction. Recently, minimally invasive surgery has been introduced for the management of rectal cancer, and transanal endoscopic microsurgery is a new method with advantages in rectal cancer treatment.

The childhood asthma is characterized as high morbidity,recurrent attack,chronic persistence and refractoriness. So asthma with these features mentioned above can have important effect on children′s emo-tional and physical development as well as their families. This review sketches the studies of children asthma family management present situation and its influencing factors,and stresses the necessity of asthma family man-agement. Methods of psychotherapy used in our country and abroad and its implementation effect are reviewed, including behavior therapy,cognitive therapy,cognitive behavioral therapy,relaxation therapy,family therapy and other existing psychological treatment,in order that these measures can be conductive to the development of pre-vention methods of pediatric asthma and further researches.

Iliac vein compression syndrome is one of the most common lower extremity venous backflow obstruction disorders,which often causes lower limb swelling,venous stasis dermatitis,lower extremity deep venous thrombosis,lower extremity venous valvular insufficiency,etc.At present the commonly used imaging diagnostic means include ultrasonography,multi-slice computed tomography,magnetic resonance and digital subtraction angiography.This paper aims to review the recent progresses in the imaging diagnosis of iliac vein compression syndrome.

Objective To observe and study the distribution and histological feature of the fascicular groups to deltoid muscle in axillary nerve at the level of quadrilateral zone. Methods 12 adult human cadavers (24 upper limbs)embalmed by formalin were used,, and microsurgical longitudinal contradissection of the axillary nerves by tracing their terminal branches were processed. At the level of quadrilateral zone,distrabution of the fscicular groups to deltoid muscle in the never trunk were recorded and their diameters were measured;Another 6 upper extremities (3 right and 3 left) of fresh-frozen human cadavers were obtained.Axillary nerves and their fascicular groups were exposured, and the segments at the level of qusdrilateral zone gotten, then histological cross section was done, acetycholinesterase (ACHE) stained with the method of Karnovsky Roots and myelin stained with the method of Loyezs. Defferent never fibres were distinguished under microscope and the fiber number was counted with IAS . Results At the level of quadrilateral zone,fasciculars were divided into two groups.The fascicular group of anterior branch to deltoid muscle was in the lateral of the nerve trunk . Its cross sectional area was (2.449?1.327)mm2 ,occupied 55.4%?9.3%of the axillary nerve trunk ;Its most fibers were motor fibers;The number of fibers is (2112?631), occupied 45.6 %?1.1%of all fibers of axillary nerve . Conclusions In the treatment of root avulsion of brachial plexus injury, selective suture donor nerve with the lateral fascicular group should be processed to repair the function of shoulder abduction,fibers loss would be reduced and rate of functional restoration improved .
