Objective To investigate the intra-splenic blood cell count of posthepatitic cirrhotic portal hypertension,and compare it with patients' peripheral blood cell count to explore the role the spleen plays in peripheral cytopenia often seen in posthepatitic cirrhotic portal hypertension.Methods A prospective study was made on 15 cases with post hepatitis B cirrhotic portal hypertension undergoing splenectomy.Intrasplenic blood was sampled from upper pole,hilus (central pole),and lower pole of the spleen respectively for blood cell count.Results were compared with that of preoperative peripheral blood.Results There were significant statistical differences in the WBC count between splenic blood and peripheral blood,(11.20 ± 4.73) × 109/L vs.(4.06 ± 1.75) × 109/L,t =5.05,P ＜ 0.05),and in PLT count,(182.45±66.57) × 109/L vs.(63.54 ±28.40) × 109/L,t =7.285,P ＜0.05.There was no differences in the RBC count,(3.55 ± 0.94) × 1012/L vs.(3.01 ± 0.62) × 1012/L,t =1.874,P ＞ 0.05.Positive correlations were found between splenic PLT count and peripheral PLT count (r =0.610,P ＜0.05).Conclusions In posthepatitic B cirrhotic portal hypertension patients the intra-megalosplenic PLT and WBC count are significantly higher than that in peripheral blood.Megalosplenic PLT count correlates positively with peripheral PLT count.

Purpose: Four and a half LIM protein 1 (FHL1) is involved in breast cancer (BC) development, but the regulatory mechanism involved remain unclear. In the present study, we examined the role of FHL1 in BC development. Methods: The expression of FHL1, miR-183-5p, and miR-96-5p in BC tissues was analyzed using StarBase analysis. FHL1 expression in BC tissues, a normal human breast epithelial cell line, and BC cell lines was detected using quantitative reverse transcription polymerase chain reaction (qRT-PCR). The relationship between FHL1 and miR-183-5p/miR-96-5p was analyzed via Pearson's rank correlation, TargetScan, and a dual-luciferase reporter assay. BT549 and MDA-MB-231 cells were transfected with either FHL1 and miR-183-5p mimics, or siFHL1 and a miR-183-5p inhibitor, respectively. The viability, colony number, migration, invasion, and tube length of BT549 and MDA-MB-231 cells were examined using cell counting kit-8, colony formation, wound-healing, Transwell, and tube formation assays, respectively. The levels of FHL1, vascular endothelial growth factor (VEGF), p53, E-cadherin, N-cadherin, and vimentin were quantified using western blotting and qRT-PCR. Results: FHL1 expression was downregulated in BC tissues and cells, whereas miR-183-5p and miR-96-5p were upregulated in BC tissues (negative correlation with FHL1 expression).FHL1 overexpression inhibited the viability, colony number, migration, and invasion of BC cells and the expression of VEGF, N-cadherin, and vimentin, and increased the expression of FHL1, p53, and E-cadherin in BT549 cells. Furthermore, a miR-183-5p mimic reversed these effects of FHL1 overexpression, whereas FHL1 silencing caused opposite results to those observed in MDA-MB-231 cells; however, this was reversed by a miR-183-5p inhibitor. Conclusion Our study suggests that miR-183-5p promotes cell proliferation, metastasis, and angiogenesis by negatively regulating FHL1 in BC.

Objective:To develop and validate the Intimate Relationships Happiness Questionnaire(IRHQ).Methods:Firstly,interviews were conducted with 20 participants,investigation were conducted with 100 partici-pants,and vocabulary scoring were conducted with 100 participants formed the originally items.Secondly,801 par-ticipants were recruited to finished the initial scale for items analysis and exploratory factor analysis.Thirdly,480 participants were conducted with the IRHQ,Satisfaction With Life Scale(SLS),Subjective Authentic-Durable Hap-piness Scale(SA-DHS),Chinese Happiness Inventory(CHI)and Marital Happiness Scale(MHS)for confirmatory factor analysis,criterion-related validity and internal consistency analysis.Finally,100 participants were assessed with IRHQ after 2 weeks for test-retest reliability.Results:After items analysis and exploratory factor analysis,29 i-tems were selected as the final scale with a total of four factors that accounted for 63.76％of the variance in all for IRHQ,4 factors including body harmony,mental harmony,fitting-value and sexual relationship satisfac-tion.Confirmatory factor analysis indicated that the four-factor model had a goof structural fit(x2/df=2.89,P＜0.001,TLI=0.93,CFI=0.94,RMSEA=0.04).The scores of IRHQ was positively correlated with the scores of SLS,SA-DHS,CHI and MHS(ICC=0.27-0.72,Ps＜0.001).The internal consistency reliabilities of the total score of the scale and the score of the 4 factors were 0.74,0.73,0.72,0.78 and 0.90.The retest reliabilities were 0.87,0.83,0.88,0.88 and 0.90.Conclusion:The Intimate Relationships Happiness Questionnaire meetsthe psy-chometric standard and could be used to assess the intimate relationship well-being.

Objective:To develop a specialized clival-cervical plate fixation (CCPF) for anterior surgery to treat craniovertebral instability, and to compare it with a posterior occipitocervical fixation (POCF) in biomechanical validation.Methods:Based on the measurement of 40 adult dry bones and 30 volunteers CT images, the clival-cervical plate was designed and manufactured. 8 cadaveric specimens (occiput-C 3) were tested in five conditions including the intact status, the intact+CCPF status, the injury status, the injury+CCPF status, and the injury+POCF status. Specimens were applied a pure moment of 1.5 N·m in flexion, extension, lateral bending, and axial rotation. Calculating and comparing the range of motion (ROM) and neutral zone (NZ) for the occiput to C 2. The effects of different fixation methods on the distribution of ROMs at the occipitocervical region were compared. Results:The injury+CCPF status constrained ROMs to 1.7° in flexion ( q=4.68, P=0.055) , 1.2° in extension ( q=0.39, P=0.9922) , 2.8° in lateral bending ( q=1.25, P=0.814) , and 4.3° in axial rotation ( q=5.08, P=0.035) , resulted in larger ROM in axial rotation but similar ROMs in other directions ( P>0.05) when compared with the injury+POCF status. There were no significant differences between the above two fixation methods in flexion-extension ( q=1.94, P=0.554) , lateral bending ( q=1.79, P=0.611) and axial rotation ( q=2.14, P=0.478) for the NZs. For the flexion, extension,lateral bendingand axial rotation direction, the proportion of the C 1, 2 ROM to the overall ROM was 28%, 25%, 34% and 56% respectively in the injury+CCPF status, and it was 59%, 53%, 42% and 71% respectively in the injury+POCF status. Conclusion:CCPF is a biomechanically effective alternative or supplemental method of POCF for the craniocervical instability.
