Transcription repressor ZHX2 is one of the members in ZHX protein family,which exists widely in human tissue and participates in the occurrence and development of various diseases.Researches show that ZHX2 is closely related to the occurrence and development of cancers,such as liver cancer,multiple myeloma,gastric cancer and colorectal cancer,which has the potential value of tumor treatment.

Notch signaling is an important evolutionarily conserved pathway involving the fate of cells translation. Additional?ly, this pathway also plays an important role in cartilage formation and maintenance of chondrocytes phenotype, regulation of the prolif?eration, maturation and balance of cartilage matrix metabolism. This paper reviews the composition and activation process of notch sig?naling, and its specific role in cartilage formation.

Objective To evaluate the value of echocardiography in investigation the failure of interventional therapy of VSDs and to increase the successful rate. Methods 15 cases with failure of VSD closure through interventional approach were undertaken measurement of major parameters of the defect on left ventriculography and then followed by Philips 5500 color Doppler US for repeated multi-direction tangential measuring of the size, morphologic change, relation with peripheral structure and individual valvular regurgitation. Results (1) Marginal membranous VSD 10 cases; membranance aneurysm 8 cases, ≥2 outlets 6 cases. Width of basal part of membranous aneurysm was 8 ～ 18 (10 ?2) mm with depth of 3 ～ 10 (6 ? 2) mm, distance from aortic valve was 0 ～ 6 (2 ? 1) mm and from tricuspid valve was 2 ～ 5 (2 ?1) mm; associated with slight tricuspid valvular regurgitation. Aortic valvular regurgitation 5 cases showed slight to mild amount and without membranous aneurysm occurred in 2 cases. (2) Intracristal VSD 5 cases showed the size of defect as 6 ～ 10 (7 ? 1) mm, with distances of 2 ～ 3 (1 ? 0.8) mm from pulmonary valve and 1 ～ 2 (1 ? 0.6) mm from aortic valve associated with slight regurgitation in 4 cases, slight tricuspid valvular regurgitation in 5 cases and aortic valvular prolapse in 4 cases. Conclusions Many factors can influence the direction tangential continuous scanning should be taken for accurate localization and measurement of VSD in order to select the very sight occludor providing high successful rate of occlusion and long term efficacy.

OBJECTIVE:To investigate the effects of 3 types of antihypertensive drugs on cognitive function in elderly hyper-tensive patients after acetabular surgery. METHODS:Ninety hypertensive patients receiving antihypertensive drugs for a long term (not changed antihypertensive drugs within 2 weeks before surgery)undergoing selective acetabular surgery were included sequen-tially and divided into angiotensin receptor blocker(ARB)group,angiotensin converting enzyme inhibitor(ACEI)group and cal-cium channel blocker(CCB)group according to the types of antihypertensive drugs,with 30 cases in each group. All patients re-ceived acetabular surgery under epidural anesthesia. The cognitive function of patients was evaluated by using MMSE 1 d before sur-gery(T0),1 d after surgery(T2)and 3 d after surgery(T3). The concentration of S100β protein serum was determined 1d before surgery (T0),immediately after surgery (T1) and 1 d after surgery (T2). RESULTS:Compared with T0,MMSE score of ARB group at T2,those of ACEI group and CCB group at T2 and T3 were decreased significantly,with statistical significance(P<0.05). Compared with ARB group,MMSE score of ACEI group and CCB group at T2,T3 were decreased significantly,with statistical sig-nificance(P<0.05). Compared with ACEI group,MMSE score of CCB group at T2,T3 were decreased significantly,with statisti-cal significance(P<0.05). Compared with T0,the concentration of S100β protein in serum 3 groups were increased significantly, with statistical significance (P<0.05). Compared with ARB group,the concentration of S100β protein serum in ACEI group and CCB group were increased significantly,with statistical significance(P<0.05). Compared with ACEI group,the concentration of S100β protein serum in CCB group at T1,T2 were increased significantly,with statistical significance(P<0.05). The incidence of cognitive dysfunction was in ascending order of ARB group (30%)

BACKGROUND: Greater tuberosity of humerus, as the attachment point of rotator cuff, plays a vital role in shoulder.Neer and AO classification for proximal humeral fractures have been accepted extensively. However, the classification for single greater tuberosity fractures of the proximal humerus is little reported, and its fixation method remains controversial.OBJECTIVE: To explore the curative efficacy of the double-row suture anchors under arthroscopy for avulsion-type greater tuberosity fractures (Mutch type Ⅰ) METHODS: Clinical data of 24 patients with avulsion-type greater tuberosity fractures (Mutch type Ⅰ) undergoing double-row suture anchors under arthroscopy were analyzed retrospectively. The displacement distance of the greater tuberosity of humerus was measured on CT before and after fixation. The shoulder joint was evaluated by Constant-Murley Score and the University of California, Los Angeles score at baseline, 1, 3, 6 and 12 months postoperatively. Besides, the visual analogue scale scores were detected at baseline and 12 months postoperatively.RESULTS AND CONCLUSION: (1) Double-row suture anchors effectively improved the displacement of greater tuberosity and rotator cuff injury. (2) The patients accompanied by rotator cuff injury accounted for 79.16%. (3) The Constant-Murley Score and the University of California, Los Angeles scores were significantly improved at each time point (P < 0.05). The visual analogue scale scores after fixation were significantly superior to those before fixation (P < 0.05). (4) These results suggest that the double-row suture anchors under arthroscopy can effectively improve the displacement of greater tuberosity and alleviate the pain. Moreover, it is conductive for early recovery of the shoulder function with little trauma, so it is a good choice for avulsion-type greater tuberosity fractures (Mutch type Ⅰ).

BACKGROUND:Anterior cruciate ligament (ACL) injury is a commonly sport-induced knee joint injury that does serious harm to the knee stability. ACL reconstruction is a commonly used treatment method, but researches on 1/2 peroneus longus tendon (PLT) graft are rarely reported. OBJECTIVE: To investigate the clinical outcomes of removing the autologous ipsilateral 1/2 PLT under arthroscopy for ACL reconstruction. METHODS:106 patients with complete ACL rupture in the Affiliated Hospital of Traditional Chinese Medicine, Southwest Medical University from December 2010 to December 2014 were enrolled, and autologous ipsilateral 1/2 PLT was removed under arthroscopy for ACL reconstruction. At baseline, 3, 6 and 12 months postoperatively, the knee stability was evaluated manually through the anterior drawer test, Lachman test, and pivot-shift test, and the knee function was evaluated by Tegner activity scale, Lysholm and International Knee Documentation Committee scores. RESULTS AND CONCLUSION: Postoperative anterior drawer test, Lachman test, and pivot-shift test tests were negative in all patients. In terms of Tegner activity scale, Lysholm and International Knee Documentation Committee scores, there were significant differences at baseline and postoperative 3 months as compared with postoperative 6 months (P < 0.05); the scores at baseline and postoperative 3 months showed significant differences compared with 12 months postoperatively (P < 0.05); the scores showed no significant difference between 6 and 12 months postoperatively (P > 0.05). These results indicate that autologous ipsilateral 1/2 PLT is a good choice for ACL reconstruction under arthroscopy, achieving rapid and satisfactory functional recovery of the knee joint, which is not only minimally invasive and easy to operate, but also exhibits good therapeutic efficacy.

Aim To investigate the effects of 6% hydroxyethyl starch 130/0.4(6%HES 130/0.4)and Ringer's solution resuscitation on early lung injury in hemorrhagic shock rats and its mechanisms.Methods Twenty-four male SD rats were divided into 4 groups:sham,Ringer's solution(RS),two HES groups(H1,H2).Group H1,H2 received HES 33,50 ml·kg~(-1) and Ringer's solutions respectively after 90-minute shock(the dose of Ringer's solutions was 3 times as muchas the maximum shed blood volume minus the dose of HES).Blood samples were taken from artery for blood analysis and the expression of CD11b/CD18 at T_0,T_1,T_4,T_5.The lungs were removed for ultrastructure examination.Results PaO_2 increased in group H1 at T_(1～5) and group H2 at T_5 as compared with T_0.PaCO_2 decreased in all the resusitation groups.The ultrastructure was basically normal except that the mitochondria changed slightly in group H1.In group H2,the perinuclear space was dilated slightly and the rough endoplasmic reticulum expanded slightly,and the degranulation was observed.Compared with group RS,the expressions of CD11b and CD18 decreased at T_4,T_5;compared with group H1,the expressions of CD11b and CD18 in group H2 increased.Conclusions Treatment with 6%HES(130/0.4)33 ml·kg~(-1)and Ringer's solution can attenuate hemorrhagic shock,and the resuscitation reduces lung injury through inhibition of expressions of CD11b and CD18.
