AIM:To evaluate the short-term efficacy of posterior chamber phakic intraocular lens implantation for moderate to high myopia.METHODS:Fifty-three eyes of 27 patients with moderate to high myopia (-3.25 to-21.5D) were received posterior chamber phakic intraocular lens implantation with 2.8mm clear corneal incision.Changes of visual acuity, intraocular pressure(IOP), counts of endothelial cells and surgically induced astigmatism at 1mo after surgery were observed.RESULTS:The preoperative best corrected visual acuity (BCVA LogMAR) were 0.05±0.18, the postoperative BCVA at 1d were 0.02±0.14, the postoperative BCVA at 1wk were-0.05±0.11, the postoperative BCVA at 1mo were-0.07±0.10.The postoperative BCVA were statistically significant differences in different time(P<0.05).The preoperative endothelial cell count was 2932.5±270.8/mm2, the postoperative endothelial cell count at 1d was 2917.1±299.0/mm2;the postoperative endothelial cell count at 1wk was 2902.5±288.6/mm2;the postoperative endothelial cell count at 1mo was 2855.3±284.2/mm2.The postoperative endothelial cell count was not statistically significant differences in different time.The preoperative IOP was 15.8±2.5mmHg;the postoperative IOP at 1d was 15.3±2.9mmHg;the postoperative IOP at 1wk was 17.4±5.8mmHg;the postoperative IOP at 1mo were 15.8±2.6mmHg.The preoperative IOP was significantly different compared with postoperative IOP at 1d, 1wk and 1mo.The postoperative IOP at 1d and 1wk were statistically significant differences (P<0.05).The surgically induced astigmatism at 1d was 0.74±0.39D;the surgically induced astigmatism at 1wk was 0.57±0.28D;the surgically induced astigmatism at 1mo was 0.44±0.21D.The postoperative IOP were statistically significant differences in different time (P<0.05).The preoperative anterior chamber depth was 3.26±0.25mm;the postoperative central vault at 1d were 654.5±345.2μm;the postoperative central vault at 1mo were 683.0±211.7μm.The postoperative central vault were significantly different between that at 1d and 1mo after operations.Operations went without serious complications.CONCLUSION:Posterior chamber phakic intraocular lens implantation for moderate to high myopia were safe, effective and predictability.But long-term effect remains needed to be further follow-up.

Postoperative surgical site infection (SSI) can lead to adverse clinical outcomes in patients, such as prolonged hospital stay, increased medical costs, and severe economic burden on patients and on society.In addition, it may also cause nosocomial cross-infection.Therefore, it has aroused the high attention of medical workers.The development of SSI is closely related to a variety of factors, including patient factors, such as blood glucose levels, smoking, systemic use of steroids, obesity and malnutrition, and perioperative related factors, such as long preoperative hospital stay, preoperative skin preparation and prophylactic use of antibiotics of patients, hand hygiene and asepsis principles of medical staff, operation-related factors, anesthetic management and operation related factors, operating room environment factors and postoperative factors.Through reading a large number of relevant literatures published in recent years and according to the work characteristics of anesthesiologists, the author summarized the influential factors and preventive measures for postoperative SSI for the reference of fellow doctors.

This paper was aimed to compare the clinical effectiveness and safety of adult male circumcision using the Shang Ring™ (SR) with the no-flip technique compared with Dorsal Slit (DS) surgical method. A single-centered, prospective study was conducted at the West China Hospital, where patients were circumcised using the no-flip SR (n = 408) or the DS (n = 94) procedure. The adverse events (AEs) and satisfaction were recorded for both groups, and ring-removal time and percentage of delayed removals were recorded for the SR group. Finally, complete follow-up data were collected for 76.1% of patients (SR: n = 306; DS: n = 76). The average ring-removal time for the SR group was 17.62 ± 6.30 days. The operation time (P < 0.001), pain scores during the procedure (P < 0.001) and at 24 h postoperatively (P < 0.001), bleeding (P = 0.001), infection (P = 0.034), and satisfaction with penile appearance (P < 0.001) in the SR group were superior to those in the DS group. After two postoperative weeks, the percentage of patients with edema in the SR group (P = 0.029) was higher but no differences were found at 4 weeks (P = 0.185) between the two groups. In conclusions, the no-flip SR method was found to be superior to the DS method for its short operation time (<5 min), involving less pain, bleeding, infection, and resulting in a satisfactory appearance. However, the time for recovery from edema took longer, and patients may wear device for 2-3 weeks after the procedure.

In this paper, we reviewed the long-term survival outcomes, safety, and quality-of-life of androgen-deprivation therapy (ADT) alone versus combined with radiation therapy (RT) or chemotherapy for locally advanced and metastatic prostate cancer (PCa). A literature search was performed using OvidSP. Randomized controlled trials (RCTs) that met the following criteria were included: including locally advanced or metastatic PCa, comparing ADT alone versus combined with any treatment method and reporting quantitative data of disease control or survival outcomes. Finally, eight RCTs met the inclusion criteria. Among these, three compared ADT versus ADT plus RT (n = 2344) and one compared ADT versus ADT plus docetaxel-estramustine (n = 413) in locally advanced PCa; two compared ADT versus ADT plus docetaxel (n = 1175) and two compared ADT versus ADT plus estramustine (n = 114) in metastatic PCa. For locally advanced PCa, the addition of RT to long-term ADT can improve the outcomes of survival and tumor control with fully acceptable adverse effects. Specially, the pooled odds ratio (OR) of overall survival (OS) was 1.43 (95% confidence interval 1.20-1.71) when compared ADT plus RT with ADT alone (P < 0.0001). For metastatic hormonally sensitive PCa, the concurrent use of docetaxel plus ADT was effective and safe (pooled OR of OS: 1.29 [1.01-1.65]: P = 0.04). In all, long-term ADT plus RT and long-term ADT plus docetaxel should be considered as proper treatment option in locally advanced and metastatic hormonally sensitive PCa, respectively. The major limitation for the paper was that only eight RCTs were available.

Recently, the D'Amico classification system is widely used for the risk stratification of prostate cancer (PCa) , although no consensus has been reached for the definition of high-risk PCa. This system defines high-risk PCa as a prostate-specific antigen (PSA) level > 20 ng/ml, a Gleason score of 8-10, or a clinical stage ≥ T2c. Because high-risk PCa is prone to recurrence and metastasis after treatment, a proper initial therapy plays a crucial role. Currently, radical prostatectomy and radiation therapy are considered to be two most important options for the initial treatment of high-risk PCa although it remains controversial which is better.
