BACKGROUND:The tourniquet is usualy fuly used or bilateraly used in partial time during bilateral total knee arthroplasty. However, very few people try to use it on one side and on the other side in partial time.
OBJECTIVE:To investigate the effective strategy of using a tourniquet in simultaneous bilateral total knee arthroplasty.
METHODS:80 patients (160 knees) with severe osteoarthritis who underwent simultaneous bilateral total knee arthroplasty in the Department of Orthopedics, Chinese PLA Medical School from January to December 2013 were divided into two groups according to the different tourniquet strategies. In test group (n=40), left knees did not receive tourniquet, and right knees received tourniquet in partial time. In control group (n=40), al knees received tourniquet in the whole time. The perioperative and postoperative blood loss, 3-day postoperative thigh sweling rate and pain visual analog scale, 3-week and 1-year postoperative Knee Society Score were recorded in both groups.
RESULTS AND CONCLUSION:There were no statisticaly significant differences between two groups in perioperative total blood loss (P > 0.05). However, postoperative blood loss in test group was less than that in control group (P < 0.05). The visual analog scale scores were significantly lower in the test group than in the control group at 3 days after surgery (P < 0.05). Visual analog scale scores on the left side were lower than on the right side in the test group at 3 days post surgery (P < 0.05). Bilateral thigh sweling rate was significantly lower in the test group than in the control group at 3 days after surgery (P < 0.05). The thigh sweling rate was lower on the left side than on the right side in the test group at 3 days after surgery (P < 0.05). Knee Society Score was higher in the test group than in the control group in the early stage, and no significant difference in long-term Knee Society Score was detected (P > 0.05). These findings verify that taking the strategy that the first knee without tourniquet and the second knee with part time tourniquet technique in simultaneous bilateral total knee arthroplasty wil aleviate pain and sweling after operation and promote early functional rehabilitation without increasing the perioperative total blood loss.

Objective To study elimination of the Micro CT projective image noise and improve the quality of the recon-structed image for the Micro CT system.Methods The forming factors of the Micro CT projective image noise were analyzed,and proposed the Micro CT projective image correction method to correct the random noise,dark field,light field,response nonuniformity and defect picture element and eliminate the random noise and the ring artifact respectively.Results Through the comparative study,it proposes a simple and practical correction method for the actual response nonuniformity which combines the corrections of light field,dark current and gain inconsistency and settles the three corrections with one circu-lation.The method can enhance the algorithm efficiency greatly and the validity of the correction protocol can be proved through experiments.Conclusion The Micro CT projective image noise is eliminated effectively and the good basis for the following work are established such as three-dimensional reconstruction.

AIM: To investigate the changes of first order kernel ( FOK ) and second order kernel ( SOK ) of multifocal electroretinogram( mf-ERG) in detecting the early retinal abnormalities in sub-clinical stage of diabetic retinopathy. ·METHODS: Totally 32 patients ( 58 eyes ) with type 2 diabetes mellitus ( DM ) without apparent diabetic retinopathy( DR) were detected by mf-ERG, from June 2014 to May 2015. Thirty cases ( 60 eyes ) of normal control group had also been taken to compare the difference of the amplitude and latency between the two groups. ·RESULTS: Compared with the control group: there was no statistical difference in the FOK b-wave latency of the diabetic group, and the FOK b-wave amplitude was significantly decreased (t=3. 099, P=0. 012). The SOK b-wave latency in diabetes group was statistically delayed (t=2. 643, P=0. 025), and the SOK b-wave amplitude statistically decreased (t=4. 833, P<0. 01). There was no statistically difference in the a-wave latency and amplitude of FOK and SOK. The b-wave amplitude of FOK and SOK was negatively correlated with the course of the disease. However, the b-wave amplitude was not statistically correlated with the duration of diabetes mellitus. ·CONCLUSION: The function of the post-polar outer and inner retina detected by FOK and SOK had been damage even before retinopathy. The anomaly is mainly reflected by the decreasing amplitude of b-wave.

Objective: To assess the association of three new single nucleotide polymorphism (SPN) sites of the transforming growth factor β1 (TGF-β1) gene, which is prevalent in Asia, with the susceptibility to the chronic hepatitis B infection-related liver disease. Methods: The genomic DNA of 129 cases suffering from the chronic HBV peripheral blood infection (74 cases with chronic type B hepatitis, 41 cases with liver cirrhosis and 14 cases with liver cancer) as well as 41 healthy volunteers were prepared. The genotypes of the TGF-β1 gene at rs2241715, rs2241716 and rs4803455 sites were detected by an allotype-specific PCR method. Results: There was a significant difference in the genotypes for rs2241715 and allele frequencies between healthy volunteers and patients with chronic type B hepatitis, liver cirrhosis, and liver cancer (P < 0.05). The individuals with rs2241715 T/T genotype had a 2.974-fold increased risk for developing chronic type B hepatitis (95% CI = 1.209-7.314, P =0.018) and 3.228-fold increased risk for developing liver cirrhosis (95% CI = 1.201-8.675, P = 0.020), while no significant correlation was observed in both genotypes and allele frequencies at rs2241716 and rs4803455 sites. Conclusion: The TGF-β1 rs2241715 T/T genotype: a predisposing factor for the chronic HBV infection-related diseases.

Contract with Dongbaogantai and observe the influence of Ganzhixiao granule on SOD, MDA and the liver function ferment. Result In the group of Ganzhixiao, the activeness of the liver’s SOD can be increased, while the content of MDA and the activeness of ALT and AST can be decreased, that is much better than Dongbaogantai. Conclusion Ganzhixiao granule has strong effect on fatty cirrhosis, and its mechanism may be concerned with the rat’s liver cell membrane and restraining damaging kuffer cell cytokine.

Objective To summarize the clinical experience of laparoscopic cholecystectomy (LC) in the treatment of acute cholecystitis. Methods A total of 93 cases of acute cholecystitis treated by LC from May 2003 to May 2005 was retrospectively reviewed, including 15 cases of preoperative endoscopic retrograde cholangiopancreatography (ERCP) combined with endoscopic sphincterotomy (EST) for common bile duct stones and 6 cases of intraoperative cholangiography. The LC was performed within 48 hours after admission. Results The LC was successfully completed in 91 cases (97.8%), whereas a conversion to open surgery was required in 2 cases (2.2%). The operation time was 35~160 min (mean, 65 min). Postoperatively, biliary leakage occurred in 3 cases (3.2%) and residual stones in the common bile duct were found in 3 cases (3.2%), which were all cured by open surgery combined with ERCP, EST, and endoscopic nasobiliary drainage (ENBD). No iatrogenic injuries happened. Conclusions With proper selection of ERCP and EST, LC for the treatment of acute cholecystitis is feasible and safe. But the incidence of conversions and complications may be high.

Objective To analysis the imaging findings of tetralogy of Fallot and related pathological basis. Methods The clinical,pathologic and right ventriculography findings of 124 tetralogy of Fallot which were confirmed by surgery were retrospectively aralyzed.
