Objective To investigate short-term clinical effect of anterolateral minimally invasive approach of total hip replacement.Methods A total of 35 patients treated by total hip replacement was divided into A and B groups.Group A used anterolateral minimally invasive approach,and group B used standard posterior Moore approach.The clinical data of operation time,amount of bleeding,blood transfusion volume,component position,Harris hip score,and complications of two groups were statistically compared.Results In terms of operation time,group A had certain disadvantages than group B.No significant difference was found between two groups in terms of operation time,annount of bleeding,blood transfusion volume,component position,Harris hip score,and complications.Conclusions In total hip replacement,anterolateral minimally invasive approach was safe and effective compared to standard posterior Moore approach.Doctors should choose their familiar surgical approach in operation.

AIM: To evaluate the accuracy of central conreal thickness ( CCT ) using EX500 Excimer Laser workstation (EX500) in laser in situ keratomileusis (LASIK) patients.METHODS:The CCT of 120 eyes (63 patients) who had LASIK between January 2013 and June 2013 were measured by A- scan and EX500. Three groups were classified: >550μm, 500 ~550μm, <500μm according the CCT value of A-scan. The CCT were measured again by corneal flap creating by moria SBK microkeratome. The thickness of the corneal bed stroma were measured by A-scan and EX500 after keratomileusis. All outcomes were analyzed with paired t test.
RESULTS: The average preoperative CCT value was 527. 9±34. 3μm measured by A-scan, 528. 5±34. 6μm measured by EX500. There was no significant difference between these two measurements (t=1. 736, P=0. 085). In group which CCT >550μm, the average preoperative CCT value was 571. 4±17. 3μm measured by A-scan, 572.7±15. 7μm measured by EX500. There was no significant difference between these two measurements (t=1. 857, P=0. 072). In group which CCT 500 ~ 550μm, the average preoperative CCT value was 523. 4±13. 1μm measured by A-scan, 524. 2±12. 4μm measured by EX500. There was no significant difference between these two measurements ( t=1. 934, P = 0. 058 ). In group which CCT <500μm, the average preoperative CCT value 484. 5±9.8μm measured by A-scan, 483. 7±8. 9μm measured by EX500. There was no significant difference between these two measurements (t=1. 395, P=0. 174). The average CCT value after corneal flap lifting was 401. 3 ± 34. 2μm measured by A-scan, 393. 4±38. 9μm measured by EX500. There was a significant difference between these two measurements ( t = 6. 669, P = 0. 000 ). The average thickness of the corneal bed stroma value after keratomileusis was 332. 6±38. 3μm measured by A-scan, 307. 3 ± 37. 1μm measured by EX500. There was a significant difference between these two measurements ( t=17. 165, P=0. 000).
CONCLUSION: There is no significant difference between preoperative CCT value measured by A-scan and EX500. After corneal flap lifting and keratomileusis, the CCT value measured by EX500 is smaller than measured by A-scan.

Acute rejection is one of the serious early postoperative complications after liver transplantation.Many studies have shown that acute rejection was mainly mediated by T cells,while humoral factors were responsible for chronic rejection.However,accumulating evidences have demonstrated that humoral immune factors also played an important role in early acute rejection and usually resulted in severe adverse events.Here we clarify the role of humoral immunity in liver transplant rejection,which may help guide the clinical management of such patients with humoral rejection after liver transplantation.

Objective To conduct a systematic review on the safety and efficacy of enhanced recov -ery after surgery ( ERAS) in perioperative management of hepatectomy .Methods A literature search was conducted on databases which included the PubMed , Embase, Cochrane Library, Sinomed, Wangfang, VIP and CNKI for randomized controlled trials ( RCTs) on application of ERAS in patients after hepatectomy . The data collection ended in August 2015.A meta-analysis was performed using RevMan 5.3 software.Re-sults Eleven RCTs which included 1074 patients were selected into this study .There were 530 patients in the ERAS group and 544 patients in the control group .On Meta-analysis, when compared with the control group, the ERAS group had significantly shorter length of hospital day (WMD=-2.36, 95%CI: -3.19~-1.54 , P<0.05 ) , shorter time for functional recovery ( WMD=-2.30 , 95%CI: -3.77 ~-0.83 , P<0.05), lower total complication rate (RR=0.65, 95%CI:0.52~0.80, P<0.05), and significantly decreased rates of postoperative pulmonary infection (RR=0.36, 95%CI:0.14~0.91, P<0.05) and nausea and vomiting (RR=0.48, 95%CI:0.26~0.89, P<0.05).There were no significant differences between the two groups on the rates of postoperative bleeding , biliary fistula, abdominal infection, delayed incisional healing, wound infection and urinary tract infection (P>0.05).The ERAS group had significant-ly lower hospitalization cost (SMD=-1.61, 95%CI:-2.42~-0.80, P<0.05), but the differences between the two groups on mortality and re-admission rates were not significant (P>0.05).When compared with the control group , the drainage tube removal time ( WMD=-2.83 , 95% CI:-3.92~-1.76 , P<0.05), time to first mobilization (SMD=-2.34, 95%CI:-2.98~-1.70, P<0.05), time to first feeding ( SMD=-5.08 , 95%CI: -9.33~-0.83 , P<0.05) , time to passage of first flatus ( SMD=-3.60, 95%CI:-4.85~-2.34, P<0.05) in the ERAS group were significantly shorter , but there was no significant difference on the time to the first bowel motion ( P>0.05 ) .Conclusions ERAS in the peri-operative management of hepatectomy was safe and beneficial .

Objective To compare everolimus (EVR) with calcineurin inhibitor (CNI) minimization or withdrawal on renal function of liver transplant patients with standard CNI therapy.Methods A search was conducted on databases which included the PubMed,Embase and Cochrane library for randomized controlled trials (RCTs) comparing EVR with CNI with minimization or withdrawal (the EVR group) with standard CNI therapy (the standard CNIs group) on renal function of liver transplant patients.A metaanalysis was performed using RevMan 5.3 software.Results Five RCTs which included 1 264 patients were selected into this study.There were 790 patients in the EVR group and 474 patients in the standard CNIs group.On meta-analysis,the EVR group had significantly better renal function (SMD =0.36,95％ CI 0.09 ～ 0.64,P ＜ 0.05),but higher rates of infection (RR =1.37,95％ CI 1.08 ～ 1.74,P ＜ 0.05),dyslipidemia (RR =2.46,95％ CI 1.79 ～ 3.38) and leukopenia (RR =2.37,95％ CI 1.32 ～ 4.26).No significant differences were found on the mortality and the acute rejection rates between the two groups (all P ＜ 0.05).Conclusions EVR with CNI minimization or withdrawal after liver transplantation provided effective immunosuppression and improved patients' renal function.The treatment increased the rates of infection,dyslipidemia and leukopenia.

Pancreatic head carcinoma could easily invade the neighboring vessels due to its own biological features and anatomical location,which increases the technique difficulty and risk,leading to low resection rate.Recently,with the progress on the surgical techniques and perioperative management,and the emergence of neoadjuvant chemoradiation,vascular invasion is no longer the surgical contraindications and pancreaticoduodenectomy combined with vascular resection has saved many patients ' lives.However,the preoperative assessment,the timing of surgery,the vessel management during the surgery,and the prevention and treatment of the postoperative complications remain controversial.In order to achieve a clear understanding on the application of pancreaticoduodenostomy combined with vascular resection,here we review the recent publications and share the experiences on pancreaticoduodenectomy with portal and/or superior mesenteric vein resection from our center,which may help improve the safety and resection rate of pancreatic carcinoma and enhance the overall therapeutic efficacy of treating pancreatic cancer.

To explore a new way of constructing bioartificial renal tubule assist device (RAD) in vitro and its function of transporting sodium (Na(+)) and glucose and to evaluate the application of atomic force microscope in the RAD construction, rat renal tubular epithelial cell line NRK-52E was cultured in vitro, seeded onto the outer surfaces of hollow fibers in a bioreactor, and then cultured for two weeks to construct RAD. Bioreactor hollow fibers without NRK-52E cells were used as control. The morphologies of attached cells were observed with scanning electron microscope, and the junctions of cells and polysulfone membrane were observed with atomic force microscope. Transportation of Na(+) and glucose was measured. Oubaine and phlorizin were used to inhibit the transporting property. The results showed that NRK-52E cells and polysulfone membrane were closely linked, as observed under atomic force microscope. After exposure to oubaine and phlorizin, transporting rates of Na(+) and glucose were decreased significantly in the RAD group as compared with that in the control group (P<0.01). Furthermore, when the inhibitors were removed, transportation of Na(+) and glucose was restored. It is concluded that a new RAD was constructed successfully in vitro, and it is able to selectively transport Na(+) and glucose.

AIM: To evaluate the changes of corneal high - order aberration (including Coma, Spab, RMSh) after laser in situ keratomileusis (LASIK) with femtosecond laser, sub- Bowman keratomileusis ( SBK ) and laser epithelial keratomileusis (LASEK). METHODS: Of 82 myopic patients ( 164 eyes ), 31 patients (62 eyes) were treated by FS-LASIK, 31 patients (62 eyes) were treated by SBK, 20 patients (40 eyes) were treated by LASEK. Sirius system was used for measuring the coma aberration, spherical aberration, and high order aberration at 1, 15d,1, 3mo after surgery. RESULTS: 1) Vision: The uncorrected visual acuity of the three groups had no differences (P>0. 05). 2) Corneal aberrations: Three kinds of surgical procedure for patients with corneal aberration had significant impact. The C7, C8, C12 and RMSh of three groups were increased significantly (P<0. 05). The C7, C8, C12 and RMSh were not recovered to preoperative levels after 3mo. But the increase of patients after FS- LASIK was smaller than the other two groups, with statistical significance (P<0. 05). CONCLUSION: Compared with SBK and LASEK, FS - LASIK has better visual acuity in the early postoperative and corneal higher-order aberrations increase is relatively small.
