1.Minimally invasive techniques in the treatment of benign prostatic hyperplasia: An update.
National Journal of Andrology 2016;22(5):387-392
Lower urinary tract symptoms (LUTS) resulting from benign prostatic hyperplasia (BPH) obviously impair the quality of life of middle-aged and elderly men. Current management of BPH includes wait-and-watch, medical therapy, and conventional surgery. As a new approach, minimally invasive surgery has been playing an increasingly important role in the management of BPH, with potential advantages of less operative trauma, quicker recovery, lower risk of postoperative complications and higher quality of life. This review mainly discusses prostatic urethral lift (Urolift® System), transurethral water vapor therapy (Rezūm® System) and robot-guided high-energy water ablation (PROCEPT Aquablation™ System).

In this study, modification technology by surface coating was used to improve the flowability of powder of Chinese herbs extracts. Seven kinds of powder of Chinese herbs extracts were coated with 1% silica nanoparticles using an under-driven Comil. The powder characteristics tester was used to evaluate the flowability of uncoated and coated powders. Surface morphology and particle size distribution of powders were compared by scanning electron microscope (SEM) and optical microscope. The powder hygroscopicity was also investigated. The results showed that, after modification, angle of repose, angle of spatula, compressibility and adhesiveness extremely decreased, and flowability index substantially increased, the powder flowability was significantly improved, especially Gegen and Dahuang extracts powders. Scanning electron microscopy images showed the distribution of silica nanoparticles on the host drug particle surfaces. There were no remarkable changes in the particle size distribution and hygroscopicity of all powders after coating. Therefore, Comilling for surface coating modification technology was an effective method to improve the flowability of Chinese herbs extracts and suggested a possible way forward to enhance the quality of Chinese drugs pharmaceutics in their study and manufacture.

Objective: To investigate the incidence of CMV infection(CMV-I) and CMV related diseases (CMV-D) after allogeneic hematopoietic stem cells transplantation in 70 consecutive allogeneic hematopoietic stem cells transplantation(allo-HSCT) patients and to search for the optimal prophylactic strategy.Methods: Blood samples were monitored using the CMV pp65 antigenemia assay.Of the 70 patients observed,30 patients with chronic myeloid leukemia[CML:CP(27),AP(2),BC(1)],12 with acute myeloblastic leukemia(AML),10 with acute lymphoblastic leukemia(ALL)and other cases were NHL(3), AA(5), MDS(7), SCLC with pancytopenia (1),CLL(1), and MF (1). Sixty six patients received HLA - identical siblings transplantation and four received tranplants from their HLA- haploidentical donors. Seventy cases included allo-PBPCT (64 cases) , allo-BMT (4 cases) and allo-PB+BMT (2). Before transplantation, all patients and donors received CMV serological examination except 4 pairs of donors/recepients. All 66 patients (3 cases were CMV IgM positive) and 64/66 donors were CMV IgG positive. Results:After transplantation, 64/70 patients developed CMV viremia during monitoring period. Forty three of 70 patients developed CMV-D.Thirty five of them suffered from CMV-associated interstitial pneumonia(CMV-IP). The high peak levels of CMV antigenemia were associated with development of CMV disease . Close correlation was found between acute graft vs host disease(GVHD) and CMV disease. The patients were followed up for 2 to 24 months. The patients who received preemptive therapy(group A)had significantly better outcome than CMV disease group(group B, P=0.0001). Conclusions: The results suggest that CMV antigenemia has high predictive value for subsequent CMV disease and CMV pp65 antigenemia -guided early therapy has particular advantage for avoiding morbidity and mortality caused by CMV disease.

BACKGROUND: Intervertebral disc degeneration (IDD) is a common cause of low back pain. Microenvironmental and cytological changes of intervertebral disc are main factors inducing disc degeneration. However, the underlying mechanism still remains unclear.OBJECTIVE: To review the application of platelet rich plasma (PRP) in the treatment of IDD.METHODS: First, the article structure was designed, and then WanFang and CNKI databases were retrieved for related articles using Chinese and English keywords. After analyzing the abstract and main body, the eligible articles were enrolled according to the inclusion and exclusion criteria.RESULTS AND CONCLUSION: Surgical treatment has achieved remarkable outcomes in the treatment of middle- and late-stage IDD. However, there is still no good conservative therapy for early degeneration. PRP has been extensively applied in the treatment of IDD due to its improvement in tissue healing and regeneration. PRP has been proved to be capable of effectively delaying and even reversing IDD through cytology tests and animal experiments. Some clinical trials have shown that PRP treatment can ease low back pain, while others have demonstrated that the combination of PRP and other biological treatments can significantly improve IDD. Nowadays, most of the experiments are limited in the study of cytology and zoology rather than clinical trials, and there is still no unified standard for extraction method, dose and optimal injection time of PRP. Moreover, there is little reported on its side effects. Consequently, the curative effect of PRP for IDD needs to be verified further.
