Platelet-rich plasma combined with microfracture versus microfracture in the treatment of knee cartilage lesions: A meta-analysis / 中国组织工程研究

OBJECTIVE: A large number of recent studies reported that microfracture combined with platelet-rich plasma has a good effect on osteochondral injury. This study systematically evaluated the clinical effect of arthroscopic platelet-rich plasma combined with microfracture versus microfracture in the treatment of knee cartilage lesions. METHODS: A randomized controlled trial of arthroscopic platelet-rich plasma combined with microfracture in the treatment of knee cartilage lesions was searched in CNKI, Wanfang Database, VIP Database, Chinese Biomedical Literature Database, PubMed, Embase and Cochrane Library. The date was from January 2001 to March 2020. The data were extracted and the quality of the included literature was evaluated, and the Rev-Man5.3 software was used for meta-analysis. RESULTS: (1) A total of seven randomized controlled trials were included, and the modified Jadad scale results showed that the scores of four studies were ≥ 4, which were high-quality literatures, and the scores of three studies were 0.05). CONCLUSION: Platelet-rich plasma combined with microfracture for knee cartilage lesions can reduce the pain in the short and medium terms, enhance the joint function in the medium and long terms, and improve the postoperative experience. However, due to the limited number of included articles, more large-sample and high-quality randomized controlled trials are needed to provide further effective data.

The value of detection of copeptin and procalcitonin in early diagnosis and prognosis of cerebral hemorrhage-associated pulmonary infection / 重庆医学

Objective To investigate that the relationship of serum concentration of copeptin ,procalcitonin(PCT )and early diagnosis ,prognosis in patients with cerebral hemorrhage‐associated pulmonary infection .Methods One hundred and twenty pa‐tients with acute cerebral hemorrhage ,acute cerebral hemorrhage‐associated pulmonary infection and 60 healthy individuals (the control group) admitted in our hospital from January 2012 to December 2013 were selected and detected for serum copeptin and procalcitonin .The differences of serum copeptin ,procalcitonin levels were compared in controls ,in patients with cerebral hemor‐rhage and cerebral hemorrhage‐associated pulmonary infection and their correlation was analyzed .Results The levels of serum copeptin in the cerebral hemorrhage‐associated pulmonary infection were significantly higher than that in control group and the cer‐ebral hemorrhage (P<0 .05) .The levels of serum procalcitonin in control group and the cerebral hemorrhage were significantly lower than that in the cerebral hemorrhage‐associated pulmonary infection ,the levels of serum C‐reactive protein ,copeptin ,procalci‐tonin and the APACHEⅡ scores of the patients with survival group were significantly lower than those with non‐survival group (P<0 .05) .Conclusion The levels of serum copeptin and procalcitonin are correlated intimately with cerebral hemorrhage‐associat‐ed pulmonary infection .They are important clinical parameters to reflect the early diagnosis and prognosis of cerebral hemorrhage‐associated pulmonary infection .

Clinical significance and the expression of NT-proBNP and copeptin in patients with acute cerebral hemorrhage / 重庆医学

Objective To investigate the relationship of plasma concentration of NT-proBNP,copeptin and glasgow coma scale(GCS)scores,hematoma volumes in patients with acute cerebral hemorrhage.Methods 109 patients with acute cerebral hem-orrhage(the cerebral hemorrhage group)and 32 healthy individuals (the control group)admitted in our hospital from December 2011 to June 2013 were selected and detected for plasma NT-proBNP and copeptin.The levels of NT-proBNP,copeptin,glasgow co-ma scale(GCS)scores and hematoma volumes were compared between the two groups.Results The levels of plasma NT-proBNP and copeptin in the cerebral hemorrhage group were significantly higher than that in control group(P <0.05).The levels of plasma NT-proBNP and copeptin were significantly increased with the severity and the hematoma volume of the acute cerebral hemorrhage. The levels of NT-proBNP and copeptin are positively correlated with hematoma volumes(r=0.63,r=0.58,P <0.01)and negative-ly correlated with Glasgow Coma Scale(GCS)scores(r=-0.52,r=-0.46,P <0.01).Conclusion The levels of NT-proBNP and copeptin are positively correlated with hematoma volumes and negatively correlated with glasgow coma scale(GCS)scores.They are important clinical parameters to reflect the severity and hematoma volumes of the acute cerebral hemorrhage.
