RESUMO
Objective:To investigate the expression of low density lipoprotein receptor associated protein 8 (LRP8) in colorectal cancer and its correlation with clinicopathological features.Methods:The surgical specimens of colorectal cancer patients hospitalized in Hunan Provincial People's Hospital from January 1, 2020 to September 1, 2020 (without adjuvant treatment measures such as radiotherapy, chemotherapy and immunotherapy) and 45 corresponding adjacent normal tissues were collected. Immunohistochemistry was used to detect the expression of LRP8 in colorectal cancer and paracancer normal tissues. The relationship between LRP8 and clinical characteristics of colorectal cancer patients was determined by univariate logistic regression analysis and Spearman correlation analysis.Results:Immunohistochemical results showed that LRP8 protein was highly expressed in 37 cases (82.22%) and low expressed in 8 cases (17.78%) of 45 colorectal cancer tissues. LRP8 protein was highly expressed in 17 cases (37.78%) and low expressed in 28 cases (62.22%). The expression of LRP8 protein in colorectal cancer tissues and adjacent normal tissues was significantly different ( P<0.05). Chi-square test showed that LRP8 protein expression was correlated with colorectal cancer stage, perineural invasion, vascular invasion, carcinoembryonic antigen (CEA) and low density lipoprotein (LDL) (all P<0.05), but not correlated with gender, age, tumor differentiation, Ki67, CA199, lymph node metastasis, triglyceride, total cholesterol and high density lipoprotein (all P>0.05). Logistic regression analysis showed that tumor node metastasis (TNM) stage, vascular invasion, nerve invasion, serum CEA and LDL levels were the influencing factors of LRP8 overexpression in patients with colorectal cancer (all P<0.05). There was a weak negative correlation between ApoB and tumor stage ( rs=-0.382), lymph node metastasis ( rs=-0.316) and vascular invasion ( rs=-0.311) (all P<0.05). Conclusions:Our results indicate that there is a higher expression of LRP8 in colorectal cancer tissues. The expression of LRP8 correlates with the staging of the colorectal cancer, neurovascular invasion, CEA, and low density lipoprotein. Patients with high expression of LRP8 have worse tumor stage and are more likely to have concurrent neurologic and vascular invasion.
RESUMO
Objective To evaluate the clinical value of Sharp-van der Heijde score (SHS)in rheumatoid arthritis (RA).Methods Clinical and X-ray of hands data in 200 patients with RA met the ACR criteria were collected in this study.Clinical DAS28,anti-cyclic citrullinated peptide antibody (aCCP)and imaging SHS were used to evaluate the activity of RA quantitatively before and after treatment.Results A moderate correlation existed between SHS and DAS28 (r s =0.61,P =0.00),but there was no significant cor-relation either between SHS and aCCP (r s = -0.1 5,P =0.03)or between aCCP and DAS28 (r s =0.14,P =0.05 ).Significant differences before and after treatment was existed in SHS (t=24.27,P =0.00)and DAS28 (t=1 5.98,P =0.00)respectively.And there was a moderate correlation between the difference in SHS before and after treatment and aCCP (r s =0.66,P =0.00).Conclu-sion The SHS,DAS28 and the aCCP in RA are closely related.Combination of three methods will help to develop the clinical pro-grams,evaluate the efficacy and prognosis.
RESUMO
Objective To summarize the methods of multiple digital replantation in different stages and improve the survival rate of replanted digits Methods In the procedure of replantation for fingertip one artery and one vein were anastomosoed, or one atrery was anastomosed accompanied with pulling out the nail and cutting small incision For middle of digit one artery and one vein were anastomosed For the proximal digit the ratio of anastomose for arteries and veins was 1 to 2 or 2 to 2 Superficial vein from arm or artery from the other finger was used if defection of vessel occur Results One hundred and twenty nine digits survived among the 142 replanted digits from 58 cases (survival rate was 90 8%),among which 113 fingers from 46 cases were subjected to following up form 3 months to 3 years, the rate of excellent and good was 85 8% Conclusion It takes more time and higher techniques to replant multiple digits To improve the survival rate, it is important to anastomose vessel excellently, deal with the defection of vessel correctly, and treat postoperative vessel crisis properly In addition, training exercise plays an important role in fnnctional recovery
