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 investigate the correlation between the characteristics of the computed tomography (CT) perfusion parameters and the expression of D2-40 with lymphatic vessel density (LVD) in cervical carcinomas.Methods A total of 42 patients with cervical carcinoma was divided into two groups with and without lymph node metastasis.Patients were evaluated with CT perfusion scan before operation.Monoclonal antibody D2-40 was used for immunohistochemistry to detect the LVD in the carcinoma tissue specimen.CT perfusion parameters and LVD of two groups were compared,and their relationship was analyzed.Results CT perfusion parameters including blood flow (BF),peak enhancement image (PEI),and blood volume (BV) in the lymph node metastasis group were significantly higher than those in the no lymph node metastasis group (t =-2.206,-2.29,-2.336,P ＜ 0.05).The time to peak (TTP) was significantly lower in the lymph node metastasis group than the no node metastasis group (t =6.908,P ＜ 0.01).The LVD in the lymph node metastasis group was significantly higher than the no lymph node metastasis group (t =-5.092,P ＜ 0.01).The CT perfusion parameters (BF,PEI,BV) and LVD of cervical carcinomas had a significantly positive correlation (r =0.65,0.56,0.61,P ＜ 0.01).The TTP and LVD had a significantly negative correlation(r =-0.55,P ＜ 0.01).Conclusions CT perfusion imaging and higher LVD help to diagnose the lymph node metastasis of a cervical carcinoma,and have important guidance role in the surgical options for cervical cancers.

Objective To study the experience of laparoscopic repair in gastric and duodenum perforation. Methods 35 patients with gastric and duodenum perforation were performed laparoscopic repair.Results 34 pati- ets with gastric and duodenum perforation were safely operated.1 case with perforation of gastric carcinoma was con- verted to open for radial gastrectomy.The mean time of hospitalization was 7.5 days.There was no intraoperative and postoperative complications.Pathological examination showed 4 patients with perforation of gastric ulcer and one with perforation of gastric carcinoma.Conclusion Laparoseopic repair was one of the safe,quick recovery and little suffering treatment for duodenum perforation.

Objective To observe the variety of liver and kidney function during lung transplantation and discuss its reference value of diagnosis and therapy in clinical acute rejection(AR).Methods The variety of TBIL, ALT and CRE were dynamically studied and analyzed before and after lung transplantation in 2 cases shared one same donor's lung block.Results During the use of CSA,TBIL diversely procedurally raised and it got right when AR was under control; when illness was worsen,ALT abnormally raised and CRE had no remarkably change.Conclusion TBIL is the sensitivity index of hepatotoxicity of immunity inhibitor CSA after lung transplantation. The abnormal change of ALT is the index of disease turnover.

The experiment was designed to investigate the effect of salvia miltiorrhiza (Danshen ) and its effective composition, phenyl lactic acid (Danshensu )on the hypoxic pulmonary vasoconstriction (HPV). Acute hypoxia was induced by replacing mixed gas 95%O2+ 5 %CO2 with 95%N2 + 5 %CO2. Hypoxic pulmonary vasoconstriction was diminished by injectic Danshen, Injectic Danshen compound and Danshensu with concentration dependently. Tile effect of Danshensu was the most,and Injectic Danshen Co was second by comparison. The results suggested that Danshen can antagonist HPV which was mainly produced by Danshensu, one of the effective composition of Danshen,and that more potent inhibitory action on HPV was by Injectio Danshen compound compared with Injectio Danshen,and this may be related to the addition of Dalbergia odorifera , the other composition of Injectic Danshen compound.
