OBJECTIVE: To review the development and mechanism of platelet-rich plasma (PRP) and the unsolved problems so as to provide reference for the clinical application of PRP.DATA SOURCES: Articles on effects of platelet-rich plasma on bone repair are searched from Medline between January 1995 and June 2005 on computer. The key words were platelet rich plasma, bone, and repair.Meanwhile, the same search was conducted to determine the correlated articles during January 1998 to June 2005 from Wanfang database with key words of platelet-rich plasma, bone and repair in Chinese.STUDY SELECTION: Literatures at home and abroad on the PRP and bone repair were chosen; Non-randomized controlled literatures were included.DATA EXTRACTION: Totally 40 out of 49 reports related to PRP and bone repair met the criteria. 9 reports were excluded due to the repeated same research. The rest 40 reports were sorted out and conducted literature review.DATA SYNTHESIS: Platelet-rich plasma was originally used in clinic to repair mandibular defect in 1998, by adding PRP to grafts with a radiographic maturation rate 1.62 to 2.16 times that of grafts without PRP. Up to now, PRP has been used in many medical areas to accelerate tissue healing due to its advantages of safety, simple, low-cost. But some problems still remain to be studied and solved.CONCLUSION: PRP includes many sorts of growth factors and has been proved to be beneficial to the maturation of both bone tissue and soft tissues. PRP is autologous and can be produced easily and safely from autologous blood, without the concerns of transmissions and immunological rejection of various diseases.

Rab GTPases serve as master regulators of vesicular membrane transport on both the exo-and endocytic pathways. Though there are many reports on Rab proteins, the function of these small proteins still remain in speculation. And no report has ever clarified the character of human Rab26. Here it was reported that a novel Rab protein Rab26 is membranous organelle related and in volved inendocytosis of HeLa cells. By using RT-PCR method a novel Rab26 cDNA full-length cDNA of Rab26 that is 1656 bp was identified.The cDNA sequence that at 1197 is 'A' other than 'G', while 'C' at 956 substitutes for 'T', and has 'GCC' insertion at 48 to 50 compared with published sequences. The complete open reading frame (ORF) is 771 bp in length encoding 256-residue protein with a calculated molecular mass of 27.9 ku (GenBank accession No.AY646153), rather than a shorter one with 190-amino acid residue as reported previously. GFP labeled full-length Rab26 expression showed that Rab26 was mainly sublocated in membranous organelles and could enhance endocytosis which means could took PE labeled protein as an endocytic tracer. RT-PCR analysis showed Rab26 was detected to express in several kinds of adenocarcinoma cell lines such as Acc2, AccM, SPC-A1 and HeLa cell lines, which indicated that Rab26 expression might be associated with some carcinomas.

Objective:To explore the correlation between middle cerebral artery (MCA) pulsatility index (PI) and total magnetic resonance imaging (MRI) burden in elderly patients with cerebral small vessel diseases (CSVD).Methods:A total of 203 CSVD inpatients aged 60 years and above who were hospitalized in the Department of Neurology of Hebei General Hospital from March 2017 to December 2020 were enrolled. The clinical data, transcranial Doppler ultrasound parameters and brain MRI data were collected. According to the total burden score, the patients were divided into low burden group (0-1 point) and high burden group (2-4 points). Univariate and multivariate Logistic regression analysis was used to analyze the correlation between MCA PI and total MRI burden in the elderly patients with CSVD. Subsequently, the receiver operating characteristic curve was used to evaluate the value of MCA PI for predicting the high MRI burden of CSVD in the elderly.Results:Hypertension ( OR=2.569, 95% CI 1.068-6.182, P=0.035), systolic blood pressure ( OR=1.033, 95% CI 1.006-1.061, P=0.016), creatinine ( OR=1.044, 95% CI 1.009-1.079, P=0.013) and MCA PI ( OR=1.125, 95% CI 1.087-1.166, P<0.001) were independently correlated with the increasing total MRI burden in the elderly patients with CSVD. Spearman rank correlation analysis revealed that there was strong and positive correlation between MCA PI and high MRI burden in the elderly patients with CSVD ( r=0.65, P<0.001). The analysis showed that when the cut-off for MCA PI was 1.11, it could identify high MRI burden of CSVD in the elderly. The area under the curve was 0.908 (95% CI 0.864-0.953, P<0.001). The sensitivity and specificity were 0.852 and 0.880, respectively. The positive predictive value was 92.38%, and the negative predictive value was 77.70%. Conclusion:The MCA PI is positively correlated with total MRI burden in the elderly patients with CSVD, and has a higher value in predicting the total MRI burden in the elderly CSVD patients, which probably bring brighter prospects for its clinical application.

Objective:To investigate the effects of applying Stent Boost Subtract (SBS) technique during percutaneous coronary intervention in patients with complex coronary lesions.Methods:200 patients with coronary artery disease (CAD) who hospitalized in the department of cardiology in Guangzhou First People′s Hospital from June 2018 to June 2020 were enrolled. The coronary lesions of all patients were corresponding to B2 or C type suggested by American Heart Association (AHA)/American College of Cardiology (ACC) according to coronary angiography and treated with percutaneous coronary intervention (PCI). Patients were randomly divided into SBS group ( n=82, SBS technique was applied during PCI) and IVUS group [ n=118, intravascular ultrasound (IVUS) was applied during PCI]. After stent implantation, quantitative coronary angiography (QCA) automatic analysis system was used to measure the related parameters of stent diameter (including the minimum, maximum and mean value of stent diameter) and calculate the stent eccentricity index. During PCI, stent eccentricity index, post-stent expansion, poorly positioned stent with open lesions, failure of overlapping stent with long lesions, mean cumulative dose (CD), product of total dose area (DAP), X-ray time, operation time and operation cost of each PCI were recorded in the two groups. Patients were followed up for 18 months after PCI, and the occurrence of adverse cardiovascular events (MACE) was recorded during the follow-up period, and the cumulative survival rate without MACE was compared between the two groups. Results:There were no statistically significant differences between the two groups in stent eccentricity index, proportion of guided stent expansion, proportion of poorly positioned stent with open lesions, proportion of stent failure to overlap, with statistically significant difference[(0.12±0.04) vs (0.10±0.03); 80.49% vs 85.49%; 2.44% vs 2.54%; 1.22% vs 2.54%, all P>0.05]. There were no significant differences in CD, X-ray time and DAP in SBS group compared with IVUS group [(1 394.18±42.29)Gy/cm 2 vs (1 391.82±45.06)Gy/cm 2; (18.79±3.01)min vs (18.95±3.12)min, (100.24±5.70)Gy/cm 2 vs (99.47±5.93)Gy/cm 2; all P>0.05]. The operation time in SBS group was shorter than that in IVUS group [(70.91±6.51)min vs (73.89±8.95)min, P<0.05], and the operation cost was less than that in IVUS group [(2.98±0.86)ten thousand yuan vs (3.85±0.81)ten thousand yuan, P<0.05]. After 18 months of follow-up after PCI, Kaplan-Meier survival analysis showed that there was no significant difference in MACE event-free survival between SBS group and IVUS group (91.46% vs 94.07%, Log Rank=0.480, P=0.489). Conclusions:SBS is a kind of convenient and effective technique in guiding PCI in patients with complex coronary lesions without increasing operation time and radiation dose, which can achieve the same effect as IVUS guidance.

Objective To compare the lung volume before and after the operation for the treatment of chronic empyema with CT 3-dimensional imaging,and to evaluate its role in the assessment of pulmonary function. Methods A total of 78 patients with chronic empyema from 2000 to 2016 in our hospital were enrolled in this study.The patients were divided into two groups according to the operational styles,with 47 cases in the decortication group and 31 cases in the catheter drainage group respectively.Reformation of the chest CT data was used to determine the lung volumes and the routine pulmonary function tests(PFT)were performed before and after the operation. The lung volumes and the PFT results before and after the operation were compared between the two groups with t test. Then multiple linear regression analysis was applied to test the relationship between the lung volumes and the values of PFT after the operation. Results The mean lung volume of catheter drainage group was(1 548±467)cm3,while it was(1 418±802) cm3for the decortication group preoperatively(t=1.665,P=0.07).After the operation,the mean lung volume of decortication group was(2 677±815)cm3,while it was(2 169±185)cm3for the catheter drainage group. There was statistically significant difference for the increase of lung volume between the two groups after operation(t=2.371,P<0.05).There was no significant difference between the two groups before the operation for the values of the PFT(t=1.467 to 1.874,P>0.05). After the operation, the values of the PFT in the decortication group were higher than those in the catheter drainage group(t=1.990 to 2.799, P<0.05). The changes of postoperative lung volume were positively correlated with the values of the PFT(β=0.312 to 0.701,P<0.05). Conclusions Decortication has a better effect on the lung volume and the pulmonary function for patients suffered from chronic empyema. CT modeling (3-dimensional-imaging) is an effective method for evaluating the pulmonary function of postoperative lung according to the lung volume measurement.
