Objective To explore the family quality of life and family support status of children with disabilities, as well as the relation-ship between them in China. Methods A total of 3198 families with children with disabilities were surveyed with Chinese Version of Family Quality of Life Scale and Family Support Scale. Results The satisfaction of family quality of life was (3.48±0.75), in the middle level. The support degree was (1.68 ± 0.57), in the low level. The family quality of life highly correlated with professional support (r=0.67, P<0.001), and also correlated with support from relatives, social organizations, friends and spouse (r=0.36~0.55, P<0.01). Conclusion China is lacking of family-centered support services to children with disabilities, that can significantly predict family quality of life. It is needed to organize the family-to-family help organizations and social welfare services, improve the social finance allowance, with the overarching purpose to improve the family quality of life for families with children with disabilities in China.

Eleven-week-old SD rats were randomized into control and calorie restriction group. The pancreatic β cell function and oxidative stress indexes in the two groups were compared after 24-week intervention. The results showed that calorie restriction, which started from young age, improved the early insulin secretion after glucose loading and alleviated the oxidative stress in adult rats, which wag related to the reduction of body weight.

The incidence of papillary thyroid carcinoma (PTC) has been increasing in the past decades.The overall survival (OS) of most PTC patients is satisfied,however,recurrence is not rare.Surgical management is the basic treatment for PTC.The first step of surgery includes gland resection and lymph node dissection of central compartment.Several controversies remain in the indications and range of surgery.In this article,the progress of gland management,lymph node dissection in central compartment and complications in PTC/papillary thyroid microcarcinoma were reviewed.

Objective To explore the effect of formaldehyde on learning and memory and the activity of superoxide dismutase (SOD) in the cerebral tissues. Methods 40 ICR mice were randomly divided into four gropes: A-control group (NS was added into water bottle), B, C, D-three formaldehyde dose groups (0.1, 0.2, 0.4% formaldehyde solution were added into water bottles). After 30 days of treatment, the ability of learning and memory were evaluated by Morris watermaze test and step-down test and the activity of SOD in the cerebral tissues was determined. Results In the Morris watermaze test (the fifth day), escapelaten latence in group C[ (29.23?5.56)s] and D[ (37.36?7.39)s] were significantly longer than group A[ (21.65?5.81)s](P

Objective:To establish a soft tissue 3-dimension(3D)finite element model of human palate.Methods:Based on the intrinsic finite element model of human maxilla,palatal mucoperiosteum flap with the thickness of 3.06 mm was added on the oral side of the plate model by ANSYS software,material property of the soft tissue was loaded,the soft tissue 3D finite element model of the palate was established.Results:By applying finite element method,the established 3D finite element model could reflect biomechani-cal properties of the soft tissue of the palate on computer.Conclusion:The 3D finite element model of the soft tissue of human palate provides the foundation for further study.

Objective:To study the impact of palatal scar force on the maxilla with unilateral cleft palate by finite element model. Methods:A 3-dimension finite element model of maxilla with cleft palate containing soft tissue was established,the soar force on the maxilla was analyzed by ansys.Results:Cleft area was identified as the center of rotation,cleft side of the maxilla reflected clock-wise rotation and non-cleft side anticlockwise rotation.The maxilla moved from outside to inside in cross section and front to back in the sagittal plane,and the former was greater than the latter.The outside of alveolar process was subjected to stress of mainly drawing force,the inside to stress of mainly compressive force.The deformation of maxilla was mainly in the front-end.Deformation of the alveolar was greater than that of maxilla body.Among deformations of three dimensions,the width was the largest,the length was the smallest,and the height was between both above.Conclusion:Along with the rotation of the maxilla,cleft area becomes gradually smaller.Among the three dimensions,the width is the largest,the length is the smallest and the height is between the both.The af-fect on maxilla is mainly in the front-end.The affect on the alveolar is greater than that on the maxilla body.

Tissue engineering of oral and maxillofacial surgery is a newly subject and animportant branch of tissue engineering. The study is to evaluate fundamental medical ethics principle in the tissue engineering of oral and maxillofacial surgery on the view medical ethcs. Strengthening the ethical education on oral and maxillofacial surgeon and right education on patients are in favor of development of tissue engineering in the oral and maxillofacial surgery.

Objective To evaluate the efficacy of using dual laser system in off clamp nephronsparing surgery.Methods We used dual laser system in the patients who underwent off-clamp NSS between Jan 2016 and Apr 2016 in our institution.There were 16 males and 8 females with average age of 49 years.Mean tumor size was 1.9 cm (range 0.8-3.2 cm).The mean R.E.N.A.L.score was 3.8 (range 3-6).The mean Zhongshan score was 3.5(range 3-5).The mean ZⅡ(zero ischemia index)was 1.6(range 1-4).The Evolve Dual (980 nm/1 470 nm) laser system set at 60 W in continuous mode was used.Results Offclamp NSS was successfully performed in 22 patients except for renal artery occlusion in 2 case.Mean operative time was 74 min(range 50-100 min);The average estimated blood loss was 52.9 ml(range 10-200 ml);Mean postoperative drainage was 65.4 ml(range 20-150ml);Mean postoperative hospital stay was 5.2 days (range:4-7days).No severe post-operative complication was found.The mean pre-and postoperative serum creatinine levels were 76.2 μmol/L(range:48-112μ mol/L) and 81.5μ mol/L(range:54-122 μ mol/L) with no significant difference(P ＞0.05).The postoperative pathology indicated that 20 cases of clear cell carcinomas,3 cases of chromophobe renal cell carcinomas,one case of papillary carcinoma.Conclusions Dual laser system can be used in off clamp nephron-sparing surgery safely and effectively.

Aim To investigate the effect of ouabain and cinobufogenin on cell proliferation,apoptosis and cell cycle on HepG2,and explore their molecular mechanism.Methods The anti-proliferative effect on HepG2 cells was determined by MTT assay.The HepG2 cells were stained with Hoechst 33342,and its morphological changes were observed under fluorescence microscope;The cell cycle was measured by flow cytometry.The Cyclin A1,CDK 2,PCNA and p21~(CIP1) expression levels of HepG2 cells treated with ouabain and cinobufogenin were dectected in mRNA and protein by Real time PCR and Western blot.Results Ouabain and cinobufogenin could inhibit cell proliferation on HepG2 cells,and the inhibitory effects were in time and dose dependent manners.The HepG2 cells treated with ouabain and cinobufogenin showed the typical morphological features of apoptosis.Cell cycle analysis showed that the S phase of HepG2 cells treated with ouabain and cinobufogenin increased significantly compared with the control group.Real-time quantitative PCR and Western blot results showed that ouabain and cinobufogenin could down-regulate Cyclin A1,CDK 2,and PCNA expressions(P<0.05)and up-regulate p21~(CIP1) expression(P<0.05).Conclusion Nα~+,K~+-ATPase inhibitor has the anti-proliferative effect on HepG2 cells and induce apoptosis and S phase arrest.These effects might be related with proteins associated with cell cycle closely.
