Objective To investigate the effect of ectodysplasin A (EDA‐A1) gene of hypohidrotic ectodermal dysplasia on pro‐liferation and cell cycle of human umbilical vein endothelial cell (ECV304). Methods Recombinant eukaryotic expression vectors pcDNA3. 1(‐)‐EDA‐A1‐M /W (mutant, M and wild, W) containing the coding sequence were transected into ECV304 cells. EDA‐A1 gene was amplified by reverse transcription polymerase chain reaction (RT‐PCR), and the protein was detected by Western blot. Cell viability and cycle distribution were invested by MTT and Flow cytometry (FCM ). Results The EDA‐A1 gene and pro‐tein were detected respectively by RT‐PCR and Western blot in ECV cells transfected with pcDNA3. 1(‐)‐EDA‐A1‐M /W, but not in ECV cells transfected with plasmid pcDNA3. 1(‐) and cells without transection. And also, compared with control groups, EDA‐A1 gene mutant significantly decreased proliferation of ECV cells and its inhibition rate was 45. 70% ( P < 0. 01), whereas wild EDA‐A1 gene did not cause such growth inhibition (P> 0. 05). A significant increase of the G0 /G1 and S fraction was seen in the ECV cells of mutant group, compared with wild group with an accumulation in S phase and a concomitant decrease in G2 /M phase population (P< 0. 05). Conclusion Mutant and wild EDA‐A1 gene may have distinct biological functions on proliferation and cell cycle distribution of cultured human umbilical vein endothelial cell.

Objective To explore the effect of high quality nursing care performing in the operating room and reasonable approach for assessment. Methods Stratified random sampling was used to select 93 nurses from two tertiary hospitals.

The effect of dark tea fermentation liquid with Eurotium Cristatum on the activity of digestive enzyme was researched, as fellowing amylase, protease, lipase. The results showed that dark tea fermentation liquid with Eurotium Cristatum may increase remarkably the activity of ?-amylase and protease, but decrease efficiently the activity of lipase. The fermentation liquid improves the digestion and absorption of starch and protein, but inhibits the decomposition and absorption of fat, so it can explain the mechanism of Fu-brick tea's health functions.

OBJECTIVETo compare therapeutic effects between surgical and conservative treatment for postoperative lumbar discitis.

METHODSFrom January 2004 to January 2009, 41 patients (17 males and 24 females ranging the age from 37 to 68 years with an average of 53.6 years) with postoperative lumbar discitis were retrospectively studied and divided into two groups. There were 19 patients in operation group, 22 patients in conservative group. Clinical data and features,image data, laboratory examinations, antibiotics utilization, hospital stays and sequelae were recorded and analyzed. Visual analogue scales system (VAS) and Oswestry disability index (ODI) were applied to evaluate therapeutic effects.

RESULTSAll patients were followed up over 2 years. Imaging revealed good bone fusion and no occurrence of discitis. VAS score and ODI at 1 month, 1 year and 2 years were significantly improved after treatment (P < 0.01). While VAS and ODI in operation group at 1 month were improved more than that of conservative group (P < 0.01), and there was no significant difference between two groups at 1 year and 2 years (P > 0.01).

CONCLUSIONSurgical and conservative treatment for postoperative lumbar discitis is effective. Surgical treatment is superior to conservative treatment in a short time, while conservative treatment can achieve long-term satisfactory curative effects.

Objective To investigate the influence of an anti-integrin α6 monoclonal antibody (GoH3) on the in vitro infection of a human keratinocyte cell line HaCaT with HPV6/11 virus particles (VP). Methods HaCaT cells were infected in vitro with 4 different concentrations of HPV6/11 VP alone, HPV6/11 VP of 106 copies/ml after incubation with 6 different dilutions of GoH3, or 8 clinical isolates of HPV6/11 VP of 106 copies/ml before or after the incubation with 1∶ 100 dilution of GoH3. After additional culture, the infected HaCaT cells were collected and fluorescence quantitative (FQ)-PCR was performed to detect the HPV DNA load in cells. The inhibition rate of CoH3 on the infection was calculated. Results The viral load was different among the HaCaT cells infected with different concentrations of HPV6/11 VP (P < 0.01). The inhibition rate on the infection positively correlated with the concentration of CoH3 when the dilution was more than 1∶ 100; however, when the dilution was less than 1∶ 100, the increase in CoH3 concentration had no influence on the inhibition rate. The average viral load in HaCaT cells infected with clinical isolates of HPV6/11 VP was (5.81 ± 2.51) × 104 copies/ml in the absence of GoH3, (3.02 ± 1.21) × 104 copies/ml with the presence of CoH3, and the average inhibition rate of GoH3 was (46.9 ± 4.7)%. Conclusions GoH3 could partially suppress the adhesion of HPV6/11 VP to HaCaT cells, hinting that integrin a6 is an important HPV6/11 VP receptor on host cells.

Objective To investigate the expression of integrin α6 mRNA in skin lesions of patients with condyloma acuminata. Methods Sixty outpatients with condyloma acuminate, including 30 primary cases and 30 recurrent cases were enrolled in the study;30 non-condyloma acuminate patients undergoing circumcision were used as normal controls. The expression of integrin α6 mRNA in condyloma acuminata lesions of primary and recurrent cases, as well as in skin samples of normal controls were determined by RTPCR. ANOVA was used to compare the differences among the groups, and Student-Newman-Keuls test(q test)was used for pairwise comparisons. Results Relative contents of integrin α6 mRNA(integrin α6/GAPDH)in normal controls, primary and recurrent condyloma acuminata lesions were 0.25±0.10, 0.79±0.16 and 1.07±0.29, respectively, and the difference was of statistical significance(F=127.687, P=0.001). Conclusion Integrin α6 may be associated with the pathogenesis and recurrence of condyloma acuminate, which may provide a new target for prevention and treatment of the disease.

The microstructures of ibuprofen-hydroxypropyl-bets-cyclodextrin (IBU-HP-beta-CyD) and ibuprofen-beta-cyclodextrin (IBU-beta-CyD) were observed by atomic force microscope (AFM). The high resolving capability of AFM has the tungsten filament probe with the spring constant of 0.06 N x m(-1). Samples were observed in a small scale scanning area of 10.5 nm x 10.5 nm and 800 x 800 pixels. The original scanning images were gained by tapping mode at room temperature. Their three-dimensional reconstruction of microstructure was performed by G3DR software. The outer diameters of HP-beta-CyD and beta-CyD are 1.53 nm. The benzene diameter of IBU is 0.62 nm, fitting to the inner diameters of HP-beta-CyD and beta-CyD. The benzene and hydrophobic chain of IBU enter into the hole of cyclodextrin at 1:1 ratio. The results were evidenced by IR, X-ray diffraction and the phase solubility.

OBJECTIVETo introduce practical diagnostic criterion of blood stasis syndrome (BSS), and to evaluate its reliability and validity.

METHODSBy referring to three diagnostic criteria of BSS [practical diagnostic criterion of BSS (criterion A), diagnostic criterion of BSS in 1986 (criterion B), Consensus of Integrative Medicine on BSS Diagnosis in 2011 (criterion C)], 712 patients from different departments of Xiyuan Hospital were recruited. The reliability of criterion A and its consistency with the other two criteria were assessed using Kappa coefficient. A Bayesian approach was also employed to assess the sensitivity and specificity of criterion A.

RESULTSAccording to the consistency check, criterion A presented good consistency when used by different researchers (the diagnostic accordance rate was 91. 96%, Kappa =0. 82, P <0.001). Meanwhile, there was an acceptable diagnostic consistency among the three diagnostic criteria. Bayesian estimation suggested that criterion A had higher sensitivity but similar specificity, as compared with criterion B or criterion C. Compared with criterion B [the median of sensitivity and specificity were 0. 762 (95% Cl: 0. 731 -0. 790) and 0. 902 (95% Cl: 0. 858 -0. 936) respectively, the median of sensitivity and specificity of criterion A were 0. 911 (95% CI: 0. 888 - 0. 930) and 0. 875 (95% CI: 0. 826 - 0. 915) respectively. Estimating the difference between criterion A and B, the median of sensitivity and specificity were 0. 149 (95% CI: 0. 112 -0.184) and -0. 026 (95% CI:-0. 085 -0. 033) respectively. Compared with criterion C [the median of sensitivity and specificity were 0. 831 (95% Cl: 0. 804 -0. 857) and 0. 892 (95% CI: 0. 848 - 0. 926) respectively], the median of sensitivity and specificity of criterion A were 0. 912 (95% CI: 0. 889 -0. 932) and 0. 880 (95%CI: 0. 833 - 0.919) respectively. Estimating the difference between criterion A and C, the median of sensitivity and specificity were 0. 081 (95% CI: 0.047 - 0.114) and -0.011 (95%CI: -0.070 -0.046) respectively.

CONCLUSIONCompared with criterion B and C, criterion A not only had better reliability, but also could significantly improve the sensitivity without obviously lowering the specificity.
