Objective To screen key genes related to deep vein thrombosis (TDVT) after trauma using gene function assembly analysis. Methods Thirty Sprague Dawley rats were randomized into control, thrombosis and non-thrombosis groups. Traumatic limb DVT models were established in rats through quantitative beating on the bilateral posterior limbs. The Genechip Rat genome 430 2. 0 genechips were applied to detect changes in genes expressions on difference phases of DVT. On the basis of the differential gene expressions in the thrombosis and non-thrombosis groups, the gene function assembly analysis was conducted to define the most significant and concentrated gene functions leading to the biological characters of DVT.Results B factor (bf), complement 4 binding protein α (C4bpα), plasminogen activator inhibitor 1 (serpinel), urokinase-type plasminogen activator receptor (plaur) were screened to be the key genes related to DVT, because they were found to be involved in the functions like complement activation, development,growth, morphogenesis, primary metabolism, cell motility, protein metabolism, localization of cell, locomotion and localization. The abundance values of the genes expressed were 1.6, -0. 2, 2. 1, 5. 1 in the thrombosis group, and -0. 5, - 1.4, 2. 7, 3. 3 in the non-thrombosis group. Conclusion Bf, C4bpα,serpinel, plaur may be the key genes that play a role in the process of DVT.

The body is exposed to various organic anions,so it is the best way to remove the toxic substances in the body quickly and effectively.Cross epithelial active transport mediated by organic anion transporter is the rate limiting process.Renal secretion and re-absorption of a variety of endogenous and exogenous organic anions are occurred in the proximal tubular epithelial cells of the organic anion transporter family.The expression of organic anion transporter-1 (OAT1) in proximal tubular epithelial cells plays an important role in the introduction of organic anion into the renal tubular epithelial cells.This article reviewed the renal expression,the substrate and the polymorphism of the organic anion transport protein OAT1,the renal toxicity of adefovir dipivoxil,the interaction between organic anion transporters and drug,and the influence of the renal toxicity on the renal toxicity of adefovir dipivoxil.

Objective:To examine the ultrastructure of resin-infiltrated sclerotic dentine following the application of an all-in-one self-etch dentin adhesive. Methods:Naturally-occurring, non-carious cervical sclerotic lesions on 10 extracted premolars were bonded using an all-in-one self-etch dentin adhesive(Adper Prompt L-Pop,3M ESPE, St Paul, USA).Artificially prepared wedge-shaped lesions were also made in 10 extracted sound premolars and restored using the same adhesive as the controls. The morphological change of dentin surface conditioned by the adhesive and the dentin-resin interface were studied by SEM.Results:Most dentinal tubules were obliterated by rod-like sclerotic casts in the non-carious cervical lesion, the sclerotic casts could not be totally dissolved by the self-etch adhesive. After restoration the resin tags were fewer and shorter in sclerotic dentin than those in sound dentin.Conclusions:Bonding to sclerotic dentin is different from that to sound dentin, and may be compromised by the fewer resin tags.

Objective To study the emmetropization in guinea pig eyes during the normal development from birth in order to provide theoretical basis to use guinea pigs as model for research on near-sightedness.Methods Sixty-four guinea pigs were assigned to 8 groups (n=8,4 male/4 female).Each group underwent a series of ocular examinations at one of the 8 time-points (0,1,2,3,5,7,9 and 11 weeks),including refraction(R),radius of corneal curvature (RCC),depth of anterior segment(AS),thickness of crystalline lens (CL),length of vitreous chamber (VC)and axial length (AL).Pooled results from both eyes of the same animals with mixed sexes can be used for further assessment of the emmetropization with the associated biometrical changes of the eye.Correlations were made between RCC,AS,CL,VC,AL and R. Results There were no significant differences between the right eye and left eye or between male and female in results of all the examinations. The refraction at birth was (+5.25?0.22 )D in guinea pigs.This value rapidly decreased during the first 3 weeks,approaching(+1.34?0.61) D by 11 weeks.There was no significant difference in refraction between 9 and 11 weeks (P= 0.215). The RCC was (3.23?0.01) mm at birth,AS was (1.20?0.00) mm at birth,CL was (2.72?0.02) mm at birth and VC was (3.27?0.01) mm at birth,they increased within the first 3 weeks despite a transient decrease in the RCC within the first week.Such an increase continued except the AS which became constant after 3 weeks.The VC was more correlated to the emmetropization (r=-0.818,P

Objective To explore the operative method and clinical effect of total hip arthroplasty with normal prosthesis in treatment of the advanced stage avascular necrosis of femoral head combined with severe femoral anteversion. Methods There were 15 patients ( 15 hips) including nine males and six females, at age range of 30-42 years (mean 37 years). The femoral anteversion was 40°-50° and Harris score of (59 ± 8) points. Total hip arthroplasty with normal prosthesis was performed to reduce the femoral anteversion for 20°-30° and increase the acetabulum anteversion for 10°-15°so as to recover a good involution relationship of the femoral head and the acetabulum and avoid anterior dislocation. The imaging examination and Harris scoring were performed regularly postoperatively. Results A follow-up for mean 2.9 years (2.5-3.7 years) in 15 patients showed that all patients obtained good range of joint motion and good stability of all the hip prostheses. Harris score was (88±6) points at 2 years post-opera-tively, which was significantly better than preoperation (P < 0.01 ). Conclusions Total hip arthro-plasty with normal prosthesis can obtain good involution of the femoral head and the acetabulum in patients with advanced stage avascular necrosis of femoral head combined with severe femoral anteversion by simul-taneously regulating implant angle of femoral prosthesis and acetabular cup, which helps avoid use of small or specially made femoral stem or subtrochanteric derotational osteotomy.

Objective To investigate the safety , feasibility , and clinical application value of digital sub-traction angiography ( DSA) -guided insertion of totally implantable venous access port ( TIVAP) in patients with digestive system cancer .Methods We retrospectively analyzed the data of 15 digestive system cancer patients who were inserted with TIVAP under DSA guidance between April 2013 and January 2016, recorded the TIVAP-related complications and indwelling time, and investigated the patients’satisfaction about TIVAP.Paired rank sum test was used for the differences in patients’quality of life before and after the insertion of TIVAP.Results Of the 15 digestive system cancer patients , operation success rate of TIVAP insertion was 100%, with the success rate of venipuncture on first attempt being 100%.The incidence of complication was 6.67% ( 1/15 ) , which was manifested as pull feeling at the neck occurring in the eighth month after insertion .The indwelling time of TIVAP was from 2 to 28 months, with a median value of 9 months.Patients’satisfaction rate of TIVAP was 86.67%(13/15).The proportion of patients with a good quality of life was 100%(15/15), statically signifi-cantly higher than that before the insertion [46.67%(7/15), Z=-3.416, P=0.000).Conclusions TIVAP insertion under DSA guidance in digestive system cancer patients is safe and feasible , with few complications and fair patient satisfaction .It may improve the patient ’s quality of life , worthy of clinical application .

OBJECTIVETo evaluate the effect of annular electrode lacrimal duct reconstruction in improving the safety and efficacy of nasolacrimal duct stent implantation for treatment of nasolacrimal duct obstruction.

METHODSThis randomized clinical trial was performed to compare the efficacy, success rate of intubation, time used for stent implantation, intraoperative pain, and extubation-assciated complications between nasolacrimal stent implantation with and without annular electrode lacrimal duct reconstruction.

RESULTSA total of 119 eligible patients were enrolled in this trial. The total curative rate at 6 months of follow up after extubation was 70.9% (83/117) in these patients, and was significnatly higher in pateinets with lacrimal duct reconstruction than in those without [80.6% (54/67) vs 58.0% (29/50); χ(2)=7.093, P<0.05]. The total success rate of stent implantation was 98.3% (117/119) in all the patients initially enrolled, and two patients experienced failure of stent implantation and were excluded; the success rate was signfiicantly higher in patients initially enrolled in the lacrimal duct reconstruction group (χ(2)=6.282, P<0.05). The median time required for intubation was shorter in lacrimal duct reconstruction group (12 s vs 33 s; Z=-36.722, P<0.05). The intendity of intraoperative pain was comparable between the two groups (t=0.833, P=0.405). The total rate of puncta injury was 43.6% (51/117) in these patients and similar between the two groups (χ(2)=1.459, P=0.227). The total rate of extubation difficulty was 9.4% (11/117) in all the patients, and was lower in lacrimal duct reconstruction group [4.5% (3/67) vs 16% (8/50); χ(2)=4.463, P<0.05]. Stent breakage in extubation occurred in 4.3% (11/117) of the patients with similar rates between the two groups (χ(2)=2.964, P=0.085). Spearman bivariate correlation analysis showed that the time required for intubation was inversely correlated with the treatment efficacy (r=-0.584, P<0.05) and positively with the occurrence of extubation difficulty (r=0.491, P<0.05); extubation difficulty was inversely correlated with the curative effect (r=-0.511, P<0.05).

CONCLUSIONAnnular electrode nasolacrimal duct reconstruction can increase the safety and efficacy of nasolacrimal duct stent implantation for treatment of nasolacrimal duct obstruction.

Human with bi-allelic WNT10A mutations and epithelial Wnt10a knockout mice present enlarged pulp chamber and apical displacement of the root furcation of multi-rooted teeth,known as taurodontism;thus,indicating the critical role of Wnt10a in tooth root morphogenesis.However,the endogenous mechanism by which epithelial Wnt10a regulates Hertwig's epithelial root sheath(HERS)cellular behaviors and contributes to root furcation patterning remains unclear.In this study,we found that HERS in the presumptive root furcating region failed to elongate at an appropriate horizontal level in K14-Cre;Wnt10afl/flmice from post-natal day 0.5(PN0.5)to PN4.5.EdU assays and immunofluorescent staining of cyclin D1 revealed significantly decreased proliferation activity of inner enamel epithelial(IEE)cells of HERS in K14-Cre;Wnt10afl/flmice at PN2.5 and PN3.5.Immunofluorescent staining of E-Cadherin and acetyl-α-Tubulin demonstrated that the IEE cells of HERS tended to divide perpendicularly to the horizontal plane,which impaired the horizontal extension of HERS in the presumptive root furcating region of K14-Cre;Wnt10afl/flmice.RNA-seq and immunofluorescence showed that the expressions of Jag1 and Notch2 were downregulated in IEE cells of HERS in K14-Cre;Wnt10afl/fl mice.Furthermore,after activation of Notch signaling in K14-Cre;Wnt10afl/flmolars by Notch2 adenovirus and kidney capsule grafts,the root furcation defect was partially rescued.Taken together,our study demonstrates that an epithelial Wnt10a-Notch signaling axis is crucial for modulating HERS cell proper proliferation and horizontal-oriented division during tooth root furcation morphogenesis.

Objective? To explore the application effect of multi-form training assessment in clinical training of geriatric nursing specialties. Methods? By convenience sampling, a total of 34 nurses under training from 14 hospitals in Beijing were selected in December 2018, and divided into experimental group(n=17) and control group(n=17) randomly. The control group adopted the traditional teaching method. A practical demand-oriented training course based on the characteristics of geriatric nursing specialties was established, and various forms of training were used, multi-station assessment of the training effect was conducted in the experimental group. The training lasted for one month in both groups. The assessment scores and satisfaction degree were compared between the groups. Results? In the experimental group, the student nurses＇ elderly patient management test score (95.0±7.5), the elderly patients specialist nursing test station test score(97.0±6.7), and the emergency response test station test score (99.0±4.5) were all higher than the control group with (86.0±8.8), (80.0±10.5), (88.0±7.6) respectively, and the differences were statistically significant (P＜0.01); the difference between the two groups of student nurses in satisfaction degree towards trainers was not statistically significant (P＞0.05); there were statistical differences between the two groups in teaching curriculum, teaching method, teaching contents, and assessment forms in both of the groups (P＜ 0.01); the overall satisfaction degree was 97.6%(83/85) in the experimental group, higher than the control group with 62.3%(53/85) and the difference was statistically significant (χ2=38.594,P＜0.001). Conclusions? Multi-form training is suitable for teaching nurses in clinical geriatric specialty. It can improve the test scores and learning satisfaction of the student nurses. Scientific curriculum, multi-form teaching methods and multi-station assessment are the key in the improvement of training quality.

Objective To evaluate the effect of Babaodan capsules combined with transcatheter arterial chemoembolization (TACE) therapy in patients with BCLC stage B primary hepatocellular carcinoma (HCC). Methods A total of 32 patients with BCLC B primary hepatocellular carcinoma who cannot be treated with operation in the Department of Oncology in Fujian Province Cancer Hospital from May 2010 to March 2013 were enrolled in the experimental group. According to paired design, 64 patients with BCLC B primary liver cancer who were treated with only TACE were as control. The patients of experimental group were treated with Babaodan capsules combined with TACE, and the patients of control group were treated with only TACE. Overall response rate (ORR), time to progression (TTP), overall survival (OS), liver function change 1 week after TACE, and post-embolization syndromes were analyzed. Measurement data were compared using t test, count data were compared with χ2test. Kaplan-Meier method was used for survival analysis, and Log-rank method for testing. Results The ORR 1.5 month after TACE was 75.0%in experimental group and 81.3%in control group(P=0.477). The median TTP was 8.9 months(95%CI 3.1-14.7 months) in experimental group, and 5.5 months (95%CI 4.3-6.7 months) in control group (P=0.048). The median OS time was 16 months(95%CI 8.0-24.0 months) in experimental group, and 12 months(95%CI 11.0-13.0 months) in control group (P=0.159). Compared with the experimental group, the alanine transaminase 1 week after TACE in control group increased obviously (P=0.018). The incidence rate of ≥CTCAE grade 2 pain after the first time TACE in experimental group was lower than that in control group(P=0.019). Conclusion Babaodan capsules could reduce pain of HCC patients after TACE, improve liver damage after TACE,and prolong the TTP of patients with BCLC stage B HCC.
