ABSTRACT
Secondary hyperparathyroidism (SHPT) is the most common complication of chronic kidney disease. It is usually manifested as a series of symptoms such as bone and joint pain, bone deformity, limb numbness and fatigue, which seriously affect the quality of patients’life. Effective therapeutic interventions are very important to reduce the mortality and morbidity of SHPT patients. For most early stage patients, durg therapy combined with adequate dialysis is very effective for disease control, but as the disease progresses, SHPT will enter the irrevesible stage and patients will become resistant to durg therapy. Surgery is the only effective treatment for advanced SHPT. However, there are still some problems such as different surgical methods, unclear surgical indications, higher perioperative risk and recurrence rate, surgery has not been widely used in clinical treatment. Now the present status of surgery treatment of SHPT is introduced in order to provide reference for the further research and development of surgery treatment.
ABSTRACT
Objective:To investigate the value of exocrine LncRNA SPINT1-AS1 in diagnosis and prognosis of papillary thyroid carcinoma (PTC) .Methods:qRT-PCR was used to detect the expression of SPINT1-AS1 in PTC tissues, cell lines (TPC-1, BCPAP, K1 and IHH4) , serum exocrine bodies of patients and normal tissues adjacent to cancer, human thyroid normal cell line Nthy-ori 3-1 and healthy volunteers. CCK-8 and colony formation assay were used to detect the effects of SPINT1-AS1 on the proliferation and colony formation of PTC cells. The interaction between SPINT1-AS1 and miR-128-3p, miR-128-3p and ITGA3 was verified by double luciferase report test.Results:The expression of SPINT1-AS1 in PTC tissues and cell lines was significantly higher than that in adjacent normal tissues and Nthy-ori 3-1 cell lines. Knockdown of SPINT1-AS1 inhibited the proliferation and colony formation of PTC cells. Bioinformatics analysis showed that there was a SPINT1-AS1/miR-128-3p/ITGA3 interaction regulatory network in PTC. The direct interaction of SPINT1-AS1, miR-128-3p and ITGA3 was verified by double luciferase reporter test. In addition, SPINT1-AS1 was significantly up-regulated in serum exocrine bodies of patients with PTC.Conclusion:Our study shows that SPINT1-AS1 regulates the miR-128-3p/ITGA3 axis to promote the proliferation and colony formation of PTC cells. Exocrine SPINT1-AS1 may be an effective molecular target for PTC in diagnosis and treatment of PTC.
ABSTRACT
Objective:To detect the expression of DKK1 in plasma and cancer tissues of patients with papillary thyroid carcinoma (PTC) , to analyze its relationship with clinicopathological parameters and β-catenin expression, and to explore the occurrence and development of DKK1 and PTC relevance.Methods:80 patients with PTC undergoing surgical treatment in Department of Thyroid Surgery, the Affiliated Hospital of Chengde Medical University from Jan. 2017 to Dec. 2019 and 100 healthy controls were included in the study. PTC tissues and paracancerous tissues of the patients were taken, and the morning fasting venous blood of the patients and healthy controls were retained. The concentrations of DKK1 and β-Catenin in plasma were detected by enzyme-linked immunosorbent assay, and the expression of DKK1 and β-Catenin in tissue was detected by immunohistochemistry.Results:The plasma DKK1 level of PTC patients was significantly lower than that of healthy controls ( t=5.863, P<0.001) , while the plasma β-catenin level was significantly higher than that of the healthy controls ( t=6.223, P<0.001) , and the plasma DKK1 and β-catenin levels of PTC patients were negatively correlated ( r=-0.724, P<0.001) ; the positive expression rate of DKK1 in PTC tissues was significantly lower than that in paracancerous tissues ( χ2=44.545, P<0.001) , while the positive expression rate of β-catenin was significantly lower than that in paracancerous tissues ( χ2=44.545, P<0.001) . The positive expression rate of DKK1 and β-catenin in PTC was significantly higher than that in paracancerous tissues ( χ2=26.243, P<0.001) , and the expression of DKK1 and β-catenin in PTC was negatively correlated ( χ2=13.637, P<0.001) . The level of plasma DKK1 in PTC patients was related to disease stage ( t=3.040, P=0.003) and lymph node metastasis ( t=5.452, P<0.001) . The positive expression rate of DKK1 in PTC tissue was also related to lymph node metastasis ( χ2=7.486, P=0.006) . In addition, the area under curve (AUC) of the diagnostic effect of plasma DKK1 level on PTC was 0.821 (95% CI=0.750-0.892, P=0.002) . Conclusion:The down-regulation of DKK1 expression in plasma and tissue is related to the occurrence and development of PTC, which has certain clinical application value.
ABSTRACT
Objective To evaluate the efficacy and safety of dezocine versus sufentanil for postoperative patient-controlled epidural analgesia (PCEA).Methods PubMed,EMBASE,Cochrane Library,ISI Web of knowledge,Chinese Biomedical Database,Chinese Science-Technology Journal Database,China Journal Full-text Database and Wanfang Database were searched for randomized controlled trials involving the efficacy and safety of dezocine and sufentanil for PCEA from the date of database establishment up to April 2014.Randomized controlled trials met the inclusion criteria were included,and the data were extracted.The quality of the trials was evaluated according to Cochrane Handbook 5.1.0 criteria.Meta-analysis was conducted using RevMan 5.1 software.Results Seven studies involving 760 patients were included in this meta-analysis.The results of meta-analyses showed that there was no significant difference between dezocine group and sufentanil group in VAS scores at 4,8,12,16,24 and 48 h after surgery and in Ramsay sedation scores at 4,12,24 and 48 h after surgery,and the incidence of adverse reactions (postoperative nausea and vomiting,pruritus,urinary retention and somnolence) was significantly lower in dezocine group than in sufentanil group,and there was no significant difference in the incidence of respiratory depression and dizziness between dezocine group and sufentanil group.Conclusion Dezocine provides better efficacy and safety for postoperative PCEA than sufentanil.
ABSTRACT
Objective To evaluate the therapeutic effect and mechanism of specific inducible nitric oxide synthase(iNOS)aminoguanidine(AG)in rats with obstructive jaundice.Methods Forty male Wistar rats were divided randomly into four groups: normal control group, sham operation group, obstructive jaundice group and aminoguanidine therapeutic group.Each group had 10 rats.We assayed levels of liver function,hemobilirubin, endotoxin,lactic acid and malondialdehyde before and after therapy, and we also analyzed pathology of the liver and small intestine.Then we could explore the therapeutic effect of AG in rats with obstructive jaundice.Results The levels of endotoxin,lactic acid and malondialdehyde in blood increased progressively along with the pathological changes of the liver and small intestine.Each of the AG group parameters was significantly lower, and the pathological changes of liver and small intestine were improved.Conclusion AG could protect liver and small intestine by attenuating lipid peroxidative and endotoxemia,and provide a new way to cure obstructive jaundice.
