?Retinal ischemia - reperfusion injury ( RlRl ) is a common clinical disease, and the producing mechanism is still in research. Experimental and clinical research in recent years have showed that the mechanism of RlRl and oxygen free radicals, gene regulation, calcium overload, inflammatory cytokines and other factors are closely related. ln this article, we summarized the current situation that the scholars at home and abroad study traditional Chinese medicine extract of prevention and treatment of RlRl.

Objective To analyze risk factors for acute kidney injury after aortic arch operation under deep hypothermic circulatory arrest.Methods Between January 2005 and June 2011,549 cases aortic arch replacement under deep hypothermic circulatory arrest were retrospectively analyzed.According to the occurrence of acute kidney injury they were divided into two groups.Univariate and multivariate analysis (multiple logistic regression) were used to identify the risk factors.Results AKI occurred in 102 cases (18.6％) and 27 cases(4.9％) had dialysis.Multiple logistic regression showed that body mess Index(OR =1.072,95％ CI:1.006-1.141,P =0.031),serum creatinin (OR =1.011,95％ CI:1.006-1.017,P =0.000),cardiopulmonary bypass time(OR =1.006,95 ％ CI:1.002-1.009,P =0.005) and the peak intraoperative glucose level (OR =1.007,95 ％ CI:1.002-1.011,P =0.003) were independent risk factors for AKI.Conclusion The higher BMI,serum creatinin level maybe indicate the occurrence of AKI,and AKI maybe can be reduced by controlling CPB time and intraoperative hyperglycemia.

Objective To investigate the changes and roles of the long non-coding RNA (IncRNA)during the reprogramming of human induced pluripotent stem cells. Methods Agilent Human lncRNA (4 × 180K) chip was used to check the expression of lncRNA in somatic cells, induced pluripotent stem cells and embryonic stem cells. Compared with differentially expressed lncRNA in somatic cells and induced pluripotent stem cells, lncRNA was selected that may play an important role during the reprogramming of human pluripotent stem cells. Results The lncRNA expression profiles in induced pluripotent stem cells were similar to embryonic stem cells, but were different from the somatic cells. A total of 3 156 differentially expressed lncRNAs were found between stem cells and somatic cells by cluster analysis, and 222 differentially expressed lncRNAs were found during the reprogramming process of human pluripotent stem cells by biological analysis. Conclusion lncRNA may play an important role in reprogramming process of human pluripotent stem.

BACKGROUND: Physical therapy is an effective treatment for movement disorder caused by central nerve system injury, while incorrect rehabilitative method will exacerbate the movement disorders in patients.OBJECTIVE: To investigate the effect of physical therapy on movement and daily activity of the patients suffering from brain injury.DESIGN: Randomized controlled study based on patients with a confirmativediagnosis.SETTING: Rehabilitation department in a university hospital.PARTICIPANTS: From September 2001 to August 2002, 78 patients hospitalized in the Rehabilitation Department of the Hospital Affiliated to Luzhou Medical College, with hemiplegia caused by brain injury, were selected into this study. The patients with severe brain injury, severe understanding disability, and severe heart diseases, lung diseases and kidney diseases were excluded.METHODS: The eligible patients were divided into two groups: the physical therapy group(48 patients) and the control group(30 patients) . All the patients in these two groups received medication and the hyperbaric oxygen therapy (HBOT), while the patients in the physical therapy group received an extra physical therapy.MAIN OUTCOMES MEASURES: A Fugl-Meyer assessment(FMA) and a modified barthel index(MBI) were adopted to evaluate the pre-and post-treatment statuses of the patients in these two groups.RESULTS: No significant difference in age, sex and disease course between the physical therapy group and the control group was found. In the physical therapy group, the FMA scale before and after the therapy were 40.43 ± 21.78 and 68.35 ±23.39, and the corresponding MBI scale were 32.82 ± 17.40 and 78.84 ± 25.31 respectively. In the control group,meanwhile, the FMA scales were 41.71 ± 19. 13 and 51.48 ± 22.58, and the MBI scales were 33.02 ± 12.48 and 56.65 ± 26.53. Before the therapy,comparison of FMA and MBI between the two groups showed no significant difference. While after the therapy, significant difference of FMA and MBI between the two groups could be confirmed( t = 2. 14, 2.21, P ＜ 0.05).CONCLUSION: Physical therapy could apparently enhance the rehabilitation of movement ability in patients with brain injury.

AIM: To analyze the effect of myopic adolescents wearing orthokeratology lens on the corneal surface curvature radius and anterior chamber depth.METHODS: Totally 120 cases of adolescent myopia were selected, among them 58 cases with 116 eyes were divided into 11-14 years old group and 62 cases with 124 eyes were 15-18 years old group according to the age.They were treated with long-term orthokeratology lens treatment, and two groups of patients were observed before wearing lens(T0), wearing for 6mo (T1), 12mo (T2) for uncorrected visual acuity, the average refractive degree improvement, the central corneal thickness, corneal curvature changes and the incidence of complications.RESULTS: The uncorrected visual acuity of the two groups at 12mo after wearing were better than that at 6mo which was better than that before wearing;the diopter had the same trend.The uncorrected visual acuity and the diopter of the 11-14 years old group at 6 and 12mo was better than those of 15-18 years old group with significant difference (P<0.05).The central corneal thickness of the two groups at 12mo after wearing were less than that at 6mo which was less than that before wearing.There was no significant difference of the central corneal thickness between the two groups at 6 and 12mo after wearing (P>0.05).The corneal anterior surface curvature of the two groups at 12mo after wearing were more than that at 6mo which was more than that before wearing.The axial length of the 11-14 years old group was longer than that of the 15-18 years old group with significant difference (P<0.05).There was no significant difference on the corneal posterior surface curvature of the two groups before and after wearing (P>0.05).There was no significant difference on the anterior chamber depth between the two groups at different time or between before and after wearing (P>0.05).CONCLUSION: Long-term wearing orthokeratology lenses have a significant effect for control ling juvenile myopia, and can improve the corneal anterior surface curvature, especially in the lower age group, and has no significant effect on the anterior chamber depth.

Objective To investigate the prognosis and recurrent factors of primary retroperitoneal liposarcoma (PRPLS).Methods The retrospective case-control study was conducted.The clinicopathological data of 51 patients with PRPLS who were admitted to the Southwest Hospital of the Third Military Medical University from January 2005 and March 2015 were collected.Observation indicators:(1) follow-up institution.(2) Analysis of prognostic factors:gender,age,tumor diameter,combined organs resection,pathological type,cancer risk and local recurrence.(3) Analysis of recurrent risk factors:gender,age,tumor diameter,combined organs resection,pathological type and cancer risk.(4) Stratified analysis:the independent risk factors of recurrence were done by the stratified analysis.(5) Correlation between cancer risk and tumor diameter or number of organs invaded.(6) Correlation between adjacent organ invasion and tumor diameter.Follow-up using outpatient examination and telephone interview was performed to detect the survival of patients and tumor recurrence up to October 2015.The survival rate and curve were respectively calculated and drawn by KaplanMeier method.The univariate analysis and survival analysis were done using the Log-rank test.The multivariate analysis was done by the COX regression model.The correlation analysis was done using the Pearson test.Results (1) Follow-up institution:51 patients were followed up for 3-114 months,with a median time of 43 months.The 3-year survival rate of 51 patients was 70.6％.Twenty-two patients had the first local recurrence,with a recurrent time of 3-60 months and a median time of 29 months.(2)Analysis of prognostic factors:the results of univariate analysis showed that tumor diameter,combined organs resection,pathological type,cancer risk and local recurrence were the related factors affecting prognosis of patients with PRPLS (x2 =5.926,4.936,17.856,17.279,14.568,P ＜ 0.05).The results of multivariate analysis showed that combined organs resection,pathological type and cancer risk were the independent factors affecting prognosis of patients with PRPLS [OR =0.538,0.645,9.620,95％ confidence interval (CI):0.238-0.997,0.458-1.058,1.692-18.714,P ＜ 0.05].(3) Analysis of recurrent risk factors:the results of univariate analysis showed that pathological type and cancer risk were the related factors affecting recurrence of patients with PRPLS (x2 =12.375,12.364,P ＜ 0.05).The results of multivariate analysis showed that cancer risk was an independent factor affecting recurrence of patients with PRPLS (OR =6.234,95％ CI:1.419-27.377,P ＜ 0.05).(4) Stratified analysis:the 3-year survival rates of 11 patients with low risk of recurrence of PRPLS and with high risk of recurrence of PRPLS were 63.6％ and 9.1％,respectively,with a statistically significant difference (x2 =12.364,P ＜ 0.05).(5)Correlation between cancer risk and tumor diameter or number of organs invaded.Tumor diameter and number of organs invaded were respectively (17 ±8)cm,1 ± 1 in 33 patients with low risk of PRPLS and (19 ±5)cm,2 ± 1 in 18 patients with high risk of PRPLS,with no statistically significant difference in tumor diameter (r =0.222,P ＞ 0.05) and with a statistically significant difference in number of organs invaded (r =0.666,P ＜ 0.05).(6)Correlation between adjacent organ invasion and tumor diameter.Tumor diameter was (16 ± 8) cm in 19 patients without adjacent organ invasion and (19 ± 7)cm in 32 patients with adjacent organ invasion,respectively,showing no statistically significant difference (r =0.225,P ＞ 0.05).Conclusions The combined organs resection,pathological type and cancer risk are independent factors affecting prognosis of patients with PRPLS,and cancer risk is an independent factor affecting recurrence of patients with PRPLS.The prognosis of patients with low risk of PRPLS is better than that with high risk of PRPLS.The organ invaded is much likely to occur in patients with high risk of PRPLS.

Objective To compare the perioperative outcomes and short-term efficacy of three-port extraperitoneal laparoscopic radical prostatectomy (ELRP) and four-port ELRP.Methods Two hundred patients who had undergone ELRP for prostate cancer by a single surgeon from November 2010 to October 2014 were retrospectively analyzed.Among them,95 cases underwent three-port ELRP and 105 cases underwent four-port ELRP.On the basis of traditional four-port ELRP,three-port ELRP was characterized by the omission of the trocar on the inner side of right anterior superior iliac spine.The mean age was 66.8 ± 15.5 years,and mean total prostate specific antigen (tPSA) was 15.3 ± 12.4 μg/L.There were no significant differences including age,body mass index,tPSA,clinical stages,acceptance of neoadjuvant hormone therapy,history of transurethral resection of the prostate,history of diabetes mellitus between the 2 groups (P ＞ 0.05).Patients in three-port ELRP group had significantly smaller prostate volume than fourport group (35.6 ± 16.7 ml versus 42.2 ± 24.7 ml,P ＜ 0.05).The clinical factors as operative time,estimated blood loss,hospital stay,drainage tube keeping days,pathological Gleason scores,pathological stages,positive surgical margin rates,biochemical recurrence rates and urinary incontinence rates were compared between the 2 groups.Results The three-port group had significantly shorter operative time than the four-port group (81.0 ± 18.6 min versus 103.6 ±34.6 min),less estimated blood loss (102.6 ±75.8 ml versus 217.5 ± 182.9 ml),less positive surgical margin rates (13.7％ versus 27.6％).There were 9 patients having Gleason scores more than 7 in the three-port ELRP group and 29 patients in four-port ELRP group (P ＜ 0.05).There were no significant differences of hospital stay,drainage tube keeping days,pathological stages between the 2 groups (P ＞ 0.05).Eighty-three cases in the three-port ELRP group (87.4％) were followed up for 5-19 months with the median time of 11 months.Ninety-two cases in fourport ELRP group (87.6％) were followed up for 17-52 months and the median time was 27 months.There were no significant differences of biochemical recurrence rates and urinary incontinence rates between the 2 groups(P ＞ 0.05).Conclusions Compared to four-port ELRP,three-port ELRP can provide shorter operative time,less blood loss,better negative surgical margin rates,similar oncological control and recovery of postoperative continence.In experienced hands,three-port ELRP could be a feasible and effective option for localized prostate cancer.

Objective To evaluate the learning curve of three-port extraperitoneal laparoscopic radical prostatectomy(ELRP) and to minimize operative time and blood loss about this procedure.Methods From August 2013 to October 2014,the data from 95 consecutive patients,who had undergone three-port ELRP for prostate cancer,were retrospectively analyzed.The mean age was 65.9 ± 7.7 years,mean total PSA level was 15.4 ± 12.7 μg/L,and mean body mass index(BMI) was 24.8 ± 3.2 kg/m2.According to the number of procedures performed by the surgeon,all patients were classified into three chronologic groups,including group A (No.1-32),group B (No.33-64) and group C (No.65-95).There were no significant differences including age,BMI,tPSA,estimated prostate volume,clinical stages,history of neoadjuvant endocrine therapy,history of transurethral resection of the prostate (TURP) among group A,B and C (P ＞ 0.05).The operative outcomes analyzed were operative time,estimated blood loss,hospital stay,drainage tube indwelling days,pathological Gleason scores,pathological stages,positive surgical margin rates,biochemical recurrence rates and urinary incontinence rates.Among these 95 patients,the results of the first 32 cases were compared with those of the remaining 63 cases,the first 64 with the remaining 31.Results The average operative time in 95 patients was 81.0 ± 18.6 min.The sloping learning curve for this surgeon showed that the operative time for all 95 cases was strongly correlated with additional experience (| rs | =0.612,P＜0.01).Operative time,however,was not strongly correlated with the surgeon's experience in each group of A,B and C(P ＞0.05).Group A had longer operative time than that of Group B plus C(96.4 ± 11.3 min vs 73.2 ± 16.7 min,P ＜0.01).Group A plus B had longer operative time than that of group C (87.6 ± 17.2 min vs 67.5 ± 13.8 min,P ＜ 0.01).For all cases,the estimated blood loss was strongly correlated with additional experience (| rs | =0.677,P ＜ 0.01).Estimated blood loss was strongly correlated with the accumulation of experience for the initial 32 cases(| rs | =0.619,P ＜ 0.01).However,no strong correlation was observed over the next 63 cases.Group A had more blood loss than that of Group B plus C (158.7 ± 81.3 ml vs 74.1 ± 54.4 ml,P ＜ 0.01).Group A plus B had more blood loss than that of group C (125.5 ± 71.6 ml vs 55.3 ± 61.6 ml,P ＜ 0.01).But hospital stay,drainage tube keeping days were not strongly correlated with additional experience in each group(P ＞ 0.05).There were no significant correlation between the accumulation of experience and positive surgical margin rates,biochemical recurrence rates and urinary incontinence rates.Conclusion Our experience of three-port ELRP cases appears to be favorable with decreasing tendency in operative time,estimated blood loss with experience accumulation.Exposure to 32 surgeries,operative time and estimated blood loss reduced significantly,and after 64 cases operative time and estimated blood loss further reduced.

Colorectal cancer is a kind of malignancies with high incidence in the worldwide, that is seriously harmed human health. So far the pathogenesis of the disease is not fully understood, this causing many difficulties to the diagnosis and treatment of the disease, and resulting in the cure rates of disease is not ideal. With the development of molecular genetics and molecular biology, many oncogenes and tumor suppressor genes have been found to be associated with the disease, and this made it is possible to reveal the pathogenesis of colorectal cancer at the molecular level. However, it is a complex and multi-step process from normal colorectal epithelial cells transformed to colorectal cancer cells, and it is the results of polygenic and multifactorial interactions. Now it is thought that the Wnt, TGF-beta, PI3K/Akt, MAPK and p53 signaling pathways are closely associated with pathogenesis of colorectal cancer. Based on the five kinds of signaling pathways as the main line, this article reviewed the roles of different signaling pathways and their related genes in the pathogenesis of colorectal cancer.
