Intraoperative cell salvage (IOCS) has been widely used to reduce allogeneic blood transfusion and prevent blood transfusion related complications during surgery.However, due to the risk of transfusion related reaction, contamination, and immunological reaction, its use for tumor patients has been controversial and limited.To explore the feasibility of the application of IOCS in cancer patients, we reported 2 cases of renal cell carcinoma (RCC) with tumor embolism in IVC that underwent radical nephrectomy,and inferior caval venous thrombectomy receiving IOCS combined with leukocyte depletion filter (LDF) from August 2016 to November 2016 in our hospital.The cell saver blood salvage (Haemone-tics, 5+) was used for these 2 cases.The salvaged blood was filtered through the LDF before infusion.For case 1 (male 45-year-old) the total operation time was 505 min, and the estimated blood loss was 4 500 ml.A total of 1 000 mL autologous blood, 12 u allogeneic packed red blood cells (PRBC), 1 200 mL fresh frozen plasma (FFP) were infused during the procedure.The patient was discharged from hospital after 75 days without complications.The postoperative follow-up for 3 months showed no tumor recurrence or metastasis.For case 2 (a male patient, aged 51 years), the total operation time was 490 min, and the estimated (blood loss was 7 000 mL.the patient received 2 700 mL autologous blood transfusion, 12 u allogeneic packed red blood cells (PRBC), and 2 400 mL fresh frozen plasma (FFP).The patient was discharged from hospital after 86 days without severe complications.the postoperative follow-up for 6 months showed no tumor recurrence or metastasis for this patient.Other relevant retrospective studies with this technique showed that cell salvage could be used safely in many kinds of cancer patients, for example, bladder cancer, liver cancer and kidney cancer.Furthermore,numerous researches have proved the safety and efficacy of the combination of these two techniques, the intraoperative cell salvage technique and leucocyte depletion filter in cancer patients.Here we only reported two cases using IOCS and LDF.Further work is needed to determine whether the use of intraoperative cell salvage combined with leukocyte depletion filter can be used safely for patients with HCC.

SUMMARY When placenta previa complicated with placenta percreta, the exposure of operative field is difficult and the routine methods are difficult to effectively control the bleeding, even causing life-threatening results. A 31-year-old woman, who had been diagnosed with a complete type of placenta pre-via and placenta percreta with bladder invasion at 34 weeks gestation. Her ultrasound results showed a complete type of placenta previa and there was a loss of the decidual interface between the placenta and the myometrium on the lower part of the uterus, suggestive of placenta increta. For further evaluation of the placenta, pelvis magnetic resonance imaging was performed, which revealed findings suspicious of a placenta percreta. She underwent elective cecarean section at 36 weeks of gestation. Firstly, two ureteral stents were placed into the bilateral ureter through the cystoscope. After the infrarenal abdominal aorta catheter was inserted via the femoral artery ( 9 F sheath ) , subarachnoid anesthesia had been estab-lished. A healthy 2 510 g infant was delivered, with Apgar scores of 10 at 1 min and 10 at 5 min. Imme-diately after the baby was delivered, following which there was massive haemorrhage and general anaes-thesia was induced. The balloon catheter was immediately inflated until the wave of dorsal artery disap-peared. With the placenta retained within the uterus, a total hysterectomy was performed. The occluding time was 30 min. The intraoperative blood loss was 2 500 mL. The occluding balloon was deflated at the end of the operation. The patient had stable vital signs and normal laboratory findings during the recovery period and the hemoglobin was 116 g/L. She was discharged six days after delivery without intervention-related complications. This case illustrates that temporary occlusion of the infrarenal abdominal aorta using balloon might be a safe and effective treatment option for patients with placenta previa complicated with placenta percreta, who were at high risk for peripartum hemorrhage. Early removal of the endovascu-lar catheter and close postoperative surveillance of the vascular system are required with this procedure to minimize the risk of vascular complications. However, further studies are needed to determine whether the potential benefits of temporary occlusion of the infrarenal abdominal aorta using balloon outweigh the potential risks.

Objective To explore the effects of long-term Tai Ji exercise on risk factors of cardiovascular diseases and incidence of chronic diseases. Methods The elderly involved were divided into control group (n=62) and Tai Ji group (n=63). Both of them received 2-years health education. The Tai Ji group exercised with the frequency of 30~40 minutes each time, 3 times a week, while the control group didn't change their daily behavior. They were observed 2 and 6 years later. Results 2 years later, the blood pressure, weight and waistline decreased in Tai Ji group compared with the control group (P<0.05). After 6 years followed, 1 people died and 4 people occured cardiovascular diseases in Tai Ji group, while 2 people died and 12 people occured cardiovascular diseases in the control group. The incidence of chronic diseases was lower in Tai Ji group (9.52%) than in the control group (33.87%) (P<0.01). And the blood pressure, waistline, and hipline in Tai Ji group decreased significantly compared with the control group (P<0.001). Conclusion Long-term Tai Ji Exercise can ameliorate the risk factors of cardiovascular diseases and reduce the incidence of chronic diseases.

In order to find an easy and rapid quantitative analytical method to detect rhamnolipid produced by Pseudomonas aeruginosa, three methods, H_ 2 SO_ 4 -anthrone analysis method, L-cysteine-H_ 2 SO_ 4 method and phenol-H_ 2 SO_ 4 method, were compared in the present paper, and the influence factors were also considered.The results showed that H_ 2 SO_ 4 -Anthrone analysis method was better than the others and its optimal reaction condition was obtained.The influence to the quantitative analysis of rhamnolipid from the residual glucose and the top clean liquid layer in the ferment solution could be ignored.But the influence from the bacterial body and the middle layer of the ferment solution reached a certain degree.Thus, the bacterial body should be removed before measuring.However, the influence from the middle layer of the ferment solution could be avoided by making a standard curve which was made by using a rhamnose mixed with the middle layer ferment solution.
