Denture adhesive(DA)Protefix was used in 31 edentulous patients with complete denture.NRS evaluation showed that applica-tion of Protefix decreased the uncomfortable score(P <0.05)at 2 h,1 d,7 d after use.Protefix improved denture retention,stability and masticatory function.

The serum level of 25-dihydroxyvitamin D3 was determined in patients with type 2 diabetes,diabetic nephropathy,and healthy objects..The results demonstrated that the serum 25-dihydroxyvitamin D3 level in type 2 diabetic patients with nephropathy was lower than that in the healthy objects or type 2 diabetes objects.Blood β2-M,total cholesterol,creatinine,24 h urinary albumin,and course of illness in type 2 diabetic patients with nephropathy have relationship with serum 25-dihydroxyvitamin D3.

Objective To study the convenient, safe and effective surgical intervention methods for correcting prominent wide lower face. Methods According to the wideness of mandibular angles, single or combined surgical treatments were performed by an intraoral approach under nerve block and local infiltration anesthesia, such as grinding mandibular angles, curved osteotomy of the angles and osteotomy of ascending ramus outer layer, partial masseter muscle resection, partial buccal fat pad removal and liposuction of cheek to reconstruct the whole lower face contour. Resnlts In the 71 cases followed up for 4 to 24 months, 60 cases were excellent, 9 were acceptable and 2 were unsatisfactory. The total satisfactory rate was 97 %. Conclusion According to the characteristics of prominent wide lower face, single or combined surgical treatments are performed to reconstruct the bone and soft tissue of lower face. This operative method is simple, safe and consistent with cosmetic surgery principle with little complications.

Objective To discuss the operative technique and curative effect of minor-incision cholecystectomy.Methods The clinical data of 672 patients with application of mini-cholecystectomy from June 2001 to June 2009 were analyzed.Perioperative management and operative technique were emphasized.Results Six hundred and fifty-two cases (97.0%) were cured with mini-cholecystectomy and 20 cases (3.0%) with incision lengthened.Operation time was (40.0?10.0) min.One case with hemorrhoea during operation was cured by interventional embolotherapy.Bile duct injury was found in 1 case during operation,and adopted suture with T tube.There were no infection of incisional wound or death in this study.Conclusion On the basis of skillful conventional cholecystectomy,by controlling indication and improving operative technique,it is an economical and safe way to perform minor-incision cholecystectomy.

Critical care medicine has the characteristics of complex,a wide range of knowledge,and interdisciplinary,so standardized training is difficult.Intensive Care Unit explored a standardized training mode and evaluation system suitable for standardized training residents in the Intensive Care Unit,including generalizing training target,developing step by step teaching plans,establishment of entrance education,basic theory,basic skills,scientific thinking and doctor-patient communication training with diversity of teaching methods,including lecture-based learning,problem-based and casebased learning,implement the flexible and strict evaluation system.

Objective To confirm the transmission of Toxoplasma gondii by semen and to investigate the impact of vaginal status on the transmission of T. gondii in female rabbits. Methods Sixteen male rabbits were infected with T. gondii by intraperitoneal injection each with 1 ×105 RH tachyzoites. Eight rabbits died in 8-14 d after infection.Artificial vagina was used to collect semen from male rabbits weekly before and after infection for 8 weeks. If more than 2 portions of semen from 8 survived male rabbits were collected after infection, the collected semen was mixed weekly for later use. Twenty-seven female rabbits were divided into 4 groups: group 1 with normal vagina (7 rabbits), group 2with wounded vagina (7), group 3 with trichomonas vaginitis (7) and group 4 with colpomycosis infection (6). Tachyzoites were found in mixed semen digested by trypsinase, and were used for endovaginal artificial insemination to female rabbits by uterine cavity tube once a week for 8 consecutive weeks. 2-3 d after every insemination, 2 ml blood was collected from helix vein of each rabbit, and stored at -40 ℃ for use. Anti-T. gondii antibody was examined by ELISA and the B1 gene of T. gondii was detected by PCR. Results Anti-T. gondii antibody was detected in some rabbits (2, 3, 1, and 1 rabbits from each of the groups respectively) on the 16th day after the first insemination. The positive rate of ELISA was 25.9%. The amplification of B1 gene (200 bp) by PCR appeared positive from the blood samples on the 3rd day after the first insemination and the last positive one was proved on the 51th day after the first insemination.Number of positive samples was 2, 1, 3 and 1 in the 4 groups respectively, with an overall PCR positive rate of 18.5%.Only 3 of the 27 rabbits were positive by both ELISA and PCR. Conclusions T. gondii can be transmitted by semen and the health status of vagina shows no impact on it.

Objective To annalyze the effect of launching blood virus nucleic acid test(NAT) centralization in Chongqing Municipal Blood Center.Methods The various links and key control points in the aspects of the transportation,detection and information system of 32 137 centralized test specimens submitted from 14 basic level local blood stations in Chongqing counties from January 2016 to June 2016 were analyzed.Results Among 32 137 centralized specimens from January to June 2016,55 specimens were rejected for various reasons,the NAT single reactive rate was 5.1‰(164/32 137),which in the Chongqing Municipal Blood Center was 2.3‰(129/55 859)during the same period.The identification detection rate in the basic level blood station was 1.8‰(57/32 137),while which in Chongqing Municipal Blood Center was only 0.6‰(35/55 859).Conclusion The effects of launching centralized NAT have already gradually emerged in Chongqing Municipal Blood Center.The detection ability and level have differences between the laboratory of basic level blood station and blood screening laboratory of blood center.Gradually increasing the centralized test degree conduces to comprehensive improvement of blood detection efficiency and blood saftey.

Objective To observe the expression and mechanism of hypoxia-inducible factor-1α (HIF-1α) and p53 protein at the altitude of 5000 meter plateau hypoxia environment in rats,as well as the effect of Astragalus injection.Methods Sixty Sprague Dawley rats were randomly divided into the Astragalus injection intervention group and normal saline control group,30 rats in each group.Astragalus injection group rats were intraperitoneal injected of Astragalus injection (15 ml/kg) before 30 minutes into the plateau environment simulation cabin,normal saline group rats were intraperitoneal injected with the same volume of saline.30 minutes after injection,rats in each group were reared in the plateau experiment cabin which simulated altitude of 5000 m (oxygen partial pressure 11.3 kPa) for 2,6,8,12,24 hours,each time period of 6 rats.When get out,the rats were executed immediately and eyes were harvested.Retinal sections were studied by hematoxylin eosin stain,and immunohistochemical method for HIF-1α and p53 expression.Results For control rats,after 2 hours in the cabin,there was edema in retinal layers.HIF-1α and p53 were expressed mainly in the cytoplasm of retinal layers.When the periods in cabin extended,there was atrophy of retinal nerve fiber layer,swelling and degeneration of ganglion cells.The expression of HIF-1α and p53 was increased.Compared with the control group,the intervention group rat had similar but less severe retinal changes,and the expression of HIF-1α and p53 was significantly decreased (P ＜0.05).Conclusion Astragalus injection can reduce pathological retinal damage in rats at high altitude environment,and its mechanism may be associated with reduced HIF-1α,p53 expression.
