We describe a manual prechop technique to divide the nucleus using a cystotome. In the cystotome-assisted prechop technique, after the capsulorhexis, the surgeon-bent cystotome is inserted into the lens while the Nagahara chopper is set around the lens equator. The cystotome and the chopper are then brought together in the center to create a bisecting crack in the nucleus, dividing it cleanly into 2 hemispheres.

The mechanisms by which Shaoyao-Gancao decoction (SGD) inhibits the production of inflammatory cytokines in serum and brain tissue after cerebral ischemia-reperfusion (CI-RP) in rats were investigated. A right middle cerebral artery occlusion was used to induce CI-RP after which the rats were divided into model (n = 39), SGD (n = 28), clopidogrel (n = 25) and sham operated (n = 34) groups. The Bederson scale was used to evaluate changes in behavioral indices. The levels of IL-1, TNF-, MCP-1, IL-10, RANTES, VEGF, and TGF-1 in the serum and infarcted brain tissues were measured. Nissl body and immunohistochemical staining methods were used to detect biochemical changes in neurons, microglial cells, and astrocytes. Serum levels of VEGF, TNF-, MCP-1, IL-1, and IL-10 increased significantly 24h after CI-RP. In brain tissue, levels of TNF- and IL-1 significantly increased 24h after CI-RP, whereas levels of TGF-1 and MCP-1 were significantly higher 96h after CI-RP (P < 0.05). SGD or clopidogrel after CI-RP reduced TNF- and IL-1 levels in brain tissue and serum levels of MCP-1, IL-1, and IL-10. SGD increased the number of NeuN-positive cells in infarcted brain tissue and reduced the number of IBA1-positive and GFAP-positive cells. The efficacy of SGD was significantly higher than that of clopidogrel.

Previous studies have demonstrated that miR-486-5p functions as a tumor suppressor or oncogene in various types of cancer. In the present study, we showed that miR-486-5p was significantly down-regulated in papillary thyroid carcinoma (PTC) tissues and cell lines, whereas miR-486-5p down-regulation inhibited PTC cell proliferation and increased apoptosis. Conversely, under-expression of miR-486-5p enhanced PTC cell proliferation and decreased apoptosis. Fibrillin-1 (FBN1) was shown to be a direct target of miR-486-5p and inversely regulated by miR-486-5p. FBN1 silencing led to decreased PTC cell proliferation and enhanced apoptosis in vitro, similar to that mediated by miR-486-5p. Furthermore, miR-486-5p over-expression or FBN1 knock-down inhibited, while up-regulation of FBN1 boosted xenograft tumor formation in vivo. Our data suggest that miR-486-5p induces PTC cell growth inhibition and apoptosis by targeting and suppressing FBN1. Thus, miR-486-5p/FBN1 might provide a promising therapeutic target for PTC treatment.

Background and purpose: An increasing interest in the potential benefits of cognitive motor interference (CMI) for stroke has recently been observed, but the efficacy of CMI for gait and balance is controversial. A systematic review and meta-analysis of randomized controlled trials was performed to estimate the effect of CMI on gait and balance in patients with stroke. Methods: Articles in Medline, EMBASE, the Cochrane Library, Web of Science, CINAHL, PEDro and the China Biology Medicine disc were searched from 1970 to July 2014. Only randomized controlled trials examining the effects of CMI for patients with stroke were included, and no language restrictions were applied. Main outcome measures included gait and balance function. Results: A total of 15 studies composed of 395 participants met the inclusion criteria, and 13 studies of 363 participants were used as data sources for the meta-analysis. Pooling revealed that CMI was superior to the control group for gait speed [mean difference (MD) 0.19 m/s, 95% confidence interval (CI) (0.06, 0.31), P = 0.003], stride length [MD 12.53 cm, 95% CI (4.07, 20.99), P = 0.004], cadence [MD 10.44 steps/min, 95% CI (4.17, 16.71), P = 0.001], centre of pressure sway area [MD -1.05, 95% CI (-1.85, -0.26), P = 0.01] and Berg balance scale [MD 2.87, 95% CI (0.54, 5.21), P = 0.02] in the short term. Conclusion: Cognitive motor interference is effective for improving gait and balance function for stroke in the short term. However, only little evidence supports assumptions regarding CMI's long-term benefits. © 2015 The Authors.

Accurate lineage tracing is crucial to understanding of developmental and stem cell biology, but is particularly challenging for transient and highly dispersive cell-types like the neural crest (NC). The authors report in this article a new zebrafish transgenic line Tg(-4725sox10:Cre)ba74. This line expresses Cre under the control of a well-characterized portion of the sox10 promoter and, by crossing to a floxed-reporter line, the authors show in this article that expression in this line is consistent with those described for GFP reporter lines using the same promoter. Reporter expression is readily detected in patterns consistent with the early expression domains. Thus, the authors see all major groups (pigment, neural, and skeletal) of NC-derived cell-types, as well as cell-types derived from the known non-NC sites of sox10 expression, including otic epithelium and oligodendrocytes. This line provides an invaluable tool for the further study of zebrafish NC development and NC-derived stem cells as well as that of the otic vesicle and oligodendrocytes. © 2012 Wiley Periodicals, Inc.

Objective: we conducted a systematic review to determine the effect of cognitive motor interference (CMI) for the prevention of falls in older adults.Methods: we searched studies through Medline, Embase, the Cochrane Library, Web of Science, CINAHL, PEDro and the China Biology Medicine disc. Only randomised controlled trials examining the effects of CMI for older people were included. The primary outcome measure was falls; the secondary outcome measures included gait, balance function and reaction time.Results: a total of 30 studies of 1,206 participants met the inclusion criteria, and 27 studies of 1,165 participants were used as data sources for the meta-analyses. The pooling revealed that CMI was superior to control group for fall rate [standard mean difference (SMD) (95% CI) = -3.03 (-4.33, -1.73), P < 0.0001], gait speed [SMD (95% CI) = 0.36 (0.07, 0.66), P = 0.01], step length [SMD (95% CI) = 0.48 (0.16, 0.80), P = 0.003], cadence [SMD (95% CI) = 0.19 (0.01, 0.36), P = 0.03], timed up and go test [SMD (95% CI) = -0.22 (-0.38, -0.06), P = 0.007], centre of pressure displacement [SMD (95% CI) = -0.32 (-1.06, 0.43), P = 0.04] and reaction time [SMD (95% CI) = -0.47 (-0.86, -0.08), P = 0.02].Conclusion: the systematic review demonstrates that CMI is effective for preventing falls in older adults in the short term. However, there is, as yet, little evidence to support claims regarding long-term benefits. Hence, future studies should investigate the long-term effectiveness of CMI in terms of fall prevention in older adults. © The Author 2014.

To search for an effective method of reducing intraoperative blood loss in radical retropubic prostatectomy (RRP). We performed RRP for 100 patients with prostate cancer, 50 (group A) with the Walsh or Poor method for handling the dorsal venous complex (DVC), and the other 50 (group B) through the following three additional procedures for hemostasis: first placing a #7 prophylactic suture in the distal position of DVC, then ligating the vascular bundle of the prostatic apex with continuous 4-0 Vicryl sutures, and lastly placing a 4-0 absorbable suture followed by freeing the neurovascular bundle (NVB) or freeing NVB before suturing the remained levator ani myofascia and the deep layer of Denovilliers' fascia above the rectal serosa with 4-0 Vicryl. We assessed the effects of the three hemostatic methods in RRP by comparing the volumes of intraoperative blood loss and transfusion, operation time and perioperative levels of hemoglobin. There were no significant differences between groups A and B in age, PSA, Gleason score, clinical stage, prostate volume, operation time and perioperative hemoglobin levels (P>0.05). The volumes of intraoperative blood loss and transfusion were markedly higher in group A ([1103.00 +/- 528.03] ml and [482.00 +/- 364.60] ml) than in B ([528.00 +/- 258.96] ml and [140.00 +/- 266.28] ml) (P<0.05). Intraoperative blood loss in RRP could be significantly decreased by placing a prophylactic hemostatic suture in the distal position of DVC, continuous suture of the vascular bundle of the prostatic apex after cutting off the urethra, and placing a fine absorbable suture above NVB or continuous suture of the remained levator ani mony fascia and the deep layer of Denovilliers'fascia above the rectal serosa with absorbable sutures after freeing NVB.

Objective: We performed a systematic review and meta-analysis to assess the effect of cognitive motor intervention (CMI) on gait and balance in Parkinson's disease. Data sources: PubMed, Embase, Cochrane Library, CINAHL, Web of Science, PEDro, and China Biology Medicine disc. Methods: We included randomized controlled trials (RCTs) and non RCTs. Two reviewers independently evaluated articles for eligibility and quality and serially abstracted data. A standardized mean difference ± standard error and 95% confidence interval (CI) was calculated for each study using Hedge's g to quantify the treatment effect. Results: Nine trials with 181 subjects, four randomized controlled trials, and five single group intervention studies were included. The pooling revealed that cognitive motor intervention can improve gait speed (Hedge's g = 0.643 ± 0.191; 95% CI: 0.269 to 1.017, P = 0.001), stride time (Hedge's g = -0.536 ± 0.167; 95% CI: -0.862 to -0.209, P = 0.001), Berg Balance Scale (Hedge's g = 0.783 ± 0.289; 95% CI: 0.218 to 1.349, P = 0.007), Unipedal Stance Test (Hedge's g = 0.440 ± 0.189; 95% CI: 0.07 to 0.81, P =0.02). Conclusions: The systematic review demonstrates that cognitive motor intervention is effective for gait and balance in Parkinson's disease. However, the paper is limited by the quality of the included trials. © The Author(s) 2015.


AIM: To investigate the influencing factors for the degree of myopia in the primary and middle school students in Pudong district of Shanghai. METHODS: A cross-sectional survey was conducted among 3 295 students in Pudong district from September to October in 2014. These students had been given vision examination and finished a questionnaire survey. Data of the survey was analyzed with rank-sum test and ordinal logistic regression analysis. RESULTS: Single factor analysis showed that there was statistical relation on degree of myopia with the grade, myopia in parents. Although there was no statistical difference between the genders, degree of myopia was different between boys and girls in different grades. There was no statistical relation on degree of myopia with time used on playing computer and mobile phone, outdoor activity time, establishment of refractive development file or monophagia. Ordinal regression analysis showed that there were statistical differences on grade, myopia in parents, establishment of refractive development file, time used on playing computer and mobile phone, frequence of wearing glasses and how to realize myopia. CONCLUSION: Grade and myopia in parents were the risk factors for degree of myopia. Ophthalmologists should strengthen the health education on myopia, advise to establish refractive development file as early as possible, monitor regularly for focus groups and control myopia progression actively.

To summarize the experience and lessons from 100 cases retropubic radical prostatectomy performed in the past 10 years. From July 1999 to July 2009, we performed 100 cases of retropubic radical prostatectomy, of which 84 were followed up for 3 - 120 months. We analyzed their preoperative age, PSA level, amount of intraoperative blood transfusion, operation time, urinary continence, penile erectile function, stricture of the anastomotic stoma and Qmax. The mean age, PSA level, amount of intraoperative blood transfusion, operation time were 66.8 yr, 20.1 ng/ml, 585.7 ml and 198.9 min; the recovery rates of bladder control at 3, 6 and 12 months postoperatively were 65.5%, 81.7% and 92.4%, respectively. At 12 months after surgery, penile erection was restored in 19 cases (42.2%), anastomotic stoma stricture developed in 5 (5.9%), Qmax averaged 20.5 ml/min, biochemical recurrence was found in 13, and 1 died from prostate cancer. Retropubic radical prostatectomy is a desirable procedure for the treatment of local prostate cancer, in which ligation of the puboprostatic ligament and prostatic venous plexus before cutting off the ligament helps improve urinary continence, protection of the neurovascular bundle and collateral pudendal artery contributes to the recovery of penile erectile function, and proper connection of urethral and bladder mucosa can reduce anastomotic stoma stricture. Postoperative external-beam radiotherapy for those with T3a or local lymph node metastasis could decrease biochemical recurrence.
