Objective To review published literatures comparing the safety and effectiveness of retroperitoneal laparoscopic partial nephrectomy (RLPN) with transperitoneal laparoscopic partial nephrectomy (TLPN) and provide reference for clinical work. Methods The search strategy was performed to identify relevant papers from the Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, Google Scholar, China Hospital Knowledge Database, Wangfang Chinese Periodical Database, and VIP Chinese Periodical Database. All papers comparing RLPN with TLPN were included from 2000 to 2015.Two to three reviewers independently screened, evaluated, and extracted the included papers. A Meta-analysis was executed by using Review Manager 5.3 software. The interesting outcomes were tumor size, operating time, estimated blood loss, warm ischaemia time, length of hospital stay, positive margin rate, open conversion rate, overall complication rate, and recurrence rate. Results The literature search obtained 378 papers, then 10 of them were ultimately met the inclusion criteria and included in the systematic review. Finally, 6 of the 10 papers were included in the Meta-analysis. RLPN had significantly less operating time [P= 0.01, mean difference (MD)=-33.68, 95% confidence interval (CI) within (-60.35,-7.01)] and shorter length of hospital stay [P< 0.0001,MD=-1.47, 95%CI within (-2.18,-0.76)] than TLPN. Significant differences were not found between RLPN and TLPN in other outcomes. Conclusions RLPN may be equally safe and be faster than TLPN. Each center can choose a modality according to your own operating habits and experience.

OBJECTIVETo explore the effect of Telbivudine (LDT) Tablet combined with Jianpi Bushen Recipe (JBR) on serum hepatitis B virus (HBV) specific cytotoxic T lymphocyte (CTL) and HBeAg seroconversion in chronic hepatitis B (CHB) patients.

METHODSTotally 90 HBeAg-positive and human leukocyte antigen (HLA)-A2 positive CHB patients were randomly assigned to the treatment group and the control group, 45 cases in each group. Patients in the treatment group took LDT Tablet (600 mg, once per day) combined with JBR granule (twice per day), while those in the control group took LDT Tablet alone. The therapeutic course for all was one year. HBV DNA negative conversion rate, HBeAg seroconversion rate, and level of HBV specific CTL were compared after 1 year treatment; liver function, drug resistance mutations, and adverse reactions were also compared between the two groups.

RESULTSAfter 1 year treatment, HBV DNA negative conversion rate and HBeAg seroconversion rate were 88.89% (40/45) and 40.00% (18/45) in the treatment group, higher than those of the control group [68.89% (31/45) and 20.00% (9/45)], with statistical difference (P < 0.05). Level of HBV specific CTL in the treatment group was 0.78% +/- 0.09% after treatment, higher than that of the control group after 1 year treatment (0.54% +/- 0.11%) and that before treatment (0.36% +/- 0.07%), with statistical difference (P < 0.01). Level of HBV specific CTL in 27 patients with HBeAg seroconversion was 0.81% 0.10%, higher than that of 63 patients without HBeAg seroconversion (0.60% +/- 0.09%), with statistical difference (P < 0.01). ALT returned to normal in 44 cases of the treatment group (97.78%), while it was 42 cases (93.33%) of the control group, with no statistical difference between the two groups (P > 0.05). Total bilirubin (TBil) in the two groups all turned to normal. rtM204I variation occurred in 1 case (2.22%) of the treatment group and 2 cases (4.44%) in the control group. No obvious adverse reaction occurred in the two groups.

CONCLUSIONLDT Tablet combined with JBR could elevate levels of HBV specific CTL and HBeAg seroconversion in CHB patients.

UNLABELLEDOBJECTIVE To observe the clinical efficacy by Qingying Huoxue Decoction (QHD) combined ursodeoxycholic acid (UDCA) in treating patients with early and mid-term primary biliary cirrhosis (PBC). METHODS Totally 78 patients were randomly assigned to the treatment group and the control group, 39 in each group. All patients received basic treatment and took UDCA (at the daily dose of 13-15 mg/kg). Patients in the treatment group took QHD, one dose per day. The treatment course for all was 6 weeks. Clinical efficacy, gamma-glutamyl transferase (γ-GGT), alkaline phospatase (ALP), TBIL, alanine aminotransferase (ALT), and aspartate transaminase (AST) were observed before and after treatment. RESULTS Totally 21 (53. 8%) patients obtained complete response in the treatment group, with statistical difference when compared with that of the control group (11 cases, 30. 8%). Levels of GGT, ALP, ALT, AST, and TBIL decreased in the two groups after treatment (P < 0.01). Levels of ALP, GGT, and TBIL were obviously lower in the treatment group than in the control group (P < 0.05).

CONCLUSIONSQHD combined UDCA in treating early and mid-term PBC patients was superior to the effect of using UDCA alone. It also could improve patients' liver function.

· AIM:To evaluate the safety and efficacy at early stage after femtosecond laser-assisted excimer laser in situ keratomileusis (FS-LASIK) combined with collagen cross-linking.· METHODS:Totally 30 myopia patients (60 eyes) received FS-LASIK combined with collagen cross-linking from July 2016 to August 2017 in our hospital were tested the uncorrected visual acuity (UCVA),Ks,Kf,surface regular index (SRI),surface asymmetry index (SAI) by corneal topography (TMS) preoperatively,1,3mo after operation.The corneal compensated intraocular pressure (IOPcc),Goldmann correlated IOP value (IOPg),corneal resistance factor (CRF),corneal hysteresis (CH) tested by ocular response analyzer (ORA) were also observed.Ziemer Galilei Dual Scheimpflug Analyzer detected the anterior diopter and the corneal thickness.Endothelial cell density were examined.· RESULTS:The postoperative UCVA remained beyond 0.8 including 26 eyes (43％) of 1d,55 eyes (92％) of 1mo,50 eyes (83％) of 3mo.IOPcc,IOPg,CRF,CH at postoperative 1mo significantly decreased comparing with preoperative (P＜0.01).IOPcc,IOPg,CRF,CH at postoperative 3mo did not change significantly comparing with 1mo (P＞0.05).The corneal topographic map parameters of Ks and Kf significantly decreased at postoperative 1mo (P ＜ 0.01),while SRI and SAI increased significantly (P＜0.01) on comparison of 1mo and preoperative.Ks of postoperative 3mo was significantly higher than that of 1 mo (P＜0.05),while Kf did not change significantly (P＞ 0.05).There was a significant decrease in SRI and SAI between 3mo and 1mo after operation (P＜ 0.05).In Galileo analysis on comparison of 3mo and 1mo,Sim Ks,Sim Kf had 0.94D,0.95D growth and the front and back surface value of Kf increased more at 3mo postoperative (P＜0.01),while Ks was no significant difference (P＞ 0.05).There was no statistically significant difference in corneal thickness between the central point and the thinnest point (P＞ 0.05).There was no significant endothelial cell loss throughout follow up (3059.95±247.87/mm2 vs 3052.87± 267.71/mm2;t=0.279,P＞0.05).· CONCLUSION:Refractive corneal surgery combined with collagen cross linking for high degree,thin cornea,uneven thickness of the cornea,topographic anomalies except for the patients with keratoconus,play a role in stabilizing corneal shape and increasing corneal biomechanics early.

Objective To explore the effect of recovery sleep on the executive function after 36 h of total sleep deprivation by event related potential technology.Methods Thirteen healthy male college students participated in two trials. At the first trial normal sleep as control was investigated. At the second trial participants experienced 36 h of sleep deprivation and then accepted 8 h recovery sleep. In each trial six Go/Nogo tests were employed to test the executive control function and the ERP data were recorded. Results There was no statistical difference in behavior and ERP results at each time point as the subjects had normal sleep. After 36 h of sleep deprivation, the behavior results were statistically significant when compared to the baseline. The amplitude and latency of Nogo-N2, Nogo-P3 on Fz electrode, the amplitude and latency of Nogo-P3 on Cz electrode showed statistical significance when compared to the baseline. After 8 h recovery sleep, the average correct reaction time and the Go correct reaction rate had statistical significance compared to 36 h value. The amplitude of Nogo-N2 and Nogo-P3 had no statistical significance compared to the baseline.However,it was of statistical significance[(-6.80 3.95)vs(-3.37 2.63)μV,(10.63±6.62)vs(5.63±5.45)μV,(9.49±7.37)vs(6.08±6.56)μV] compared to 36 h value. The latency of the recovery value of Nogo-N2 and Nogo-P3 was statistically significant[(254.14±15.55)vs(243.08±13.97)ms(382.14±41.07)vs(349.17±30.36)ms,(369.86±26.48)vs(347.48±29.24)ms]compared to the baseline.Conclusion As the time of sleep deprivation is prolonged, the executive function is impaired and the executive function is not completely recovered after 8 h recovery sleep.

Objective: To observe the controlled hypotension effects of nicardipine in 2 different ways for spinal tumor operalion. Methods: Twenty-four adult patients, scheduled for selective spinal tumor operation, were randomly divided into 2 groups. In groupⅠ(n=12), the nicardipine was infused at a rate of 10 μg*kg-1*min-1 and the infusion continued until MAP was at the level of 7.33-8.66 kPa, and then the rate was decreased to 1 μg*kg-1*min-1. In Group Ⅱ(n=12), nicardipine was given 0.01-0.02 mg/kg as the load dose, then infused at 1-2 μg*kg-1*min-1. Results: During the period of controlled hypotension, cardiac index(CI) increased significantly, other hemodynamic variables were stable and no hypertension rebound occurred in both groups. Reaching time of target blood pressure in groupⅡ was shorter than that in groupⅠ（P＜0.05）. The dose required to obtain target blood pressure in group Ⅱwas less than that in group Ⅰ（P＜0.05）. BP recovery time from discontinuing nicardipine infusion to pre-hypotension level,bleeding volume and transfusion volume were similar between 2 groups（P＞0.05）.During mass bleeding,　serious arrhythmia and oliguria did not occur in any case. Conclusion: Controlled hypotension with nicardipine is rapid, stable and easily controlled without hypertension rebound. Nicardipine has considerable protective effects on heart and kidney during mass bleeding. The method of bolus injection followed with intravenous infusion is more suitable to clinical application.

This study was aimed to investigate the efficiency of modified methylation-specific polymerase chain reaction i.e. nested methylation-specific polymerase chain reaction, used to detect the promoter methylation of p16 gene in six hematological malignant cell lines, and to explore the application in selection of hematological malignant cell lines with promoter hypermethylation, and make them to be an idel cell models for studying the relationship between gene methylation and expression. DNAs were denatured by NaOH and then were subjected to bisulfite modification and a nested-MSP was used to amplify the promoter region, nested MSP product of p16 gene promoter was analyzed and sequenced. The results showed that the hypermethylation of p16 gene was detected in CA46 and U266, however, Molt4, K562, HL-60 and Jurkat cell lines were unmethylated. In conclusion, p16 gene methylation in hematological malignant cell lines can be perfectly detected by nested-MSP method, which is simple, sensitive and specific for screening all kinds of hematological malignant cell lines with p16 gene methylated.
