Objective To evaluate the method, clinical effects and influential factors of using three dimensional external fixators in the treatment of severe open comminuted tibiofibular fractures 5 cm near the knee or ankle joints. Methods We retrospectively analyzed 32 cases of open comminuted tibiofibular fracture 5 cm near the knee (11 cases) or ankle joints (21 cases). They were treated with three dimensional external fixators from October 2000 to May 2005. The patients with small wounds were treated with manipulative reduction or leverage reduction through the wound under the guidance of C-arm radiography. In case of malreduction or soft tissue being tangled by the fracture ends, visible reduction was carried out after the wound was lengthened or a small incision was added. Limited internal fixation was used in case of necessity. The results were evaluated in terms of shortening of the fractured limbs, X-ray manifestation, bilateral flexion differences and postoperative walking complaints. Results Follow-ups from 5 to 18 months (nine months on average) showed that all the cases achieved osseous union. The mean union time was 5.6 months. The total excellent and good rates of fracture healing and functional recovery were 81.3% and 87.5% respectively. Conclusion Application of the three dimensional external fixator is appropriate for the treatment of severe open comminuted tibiofibular fracture 5 cm near the knee or ankle joints, because its operative procedure is simple, the injury it causes is minimal, its fixation is reliable and its complications are quite limited.

Objective:To investigate the anesthetic choice for patients undergoing cesarean section complicated with placenta implantation.Methods: A retrospective case review of the patients with placenta implantation between 2008 and 2013 at Peking University Third Hospital was conducted in the International Classification of Diseases (ICD)-9 codes,excluding natural birth and not first diagnosed in our hospital,a total of 96 cases were incorporated into this study.According to the degree of implantation,they were divided into three groups: accreta group,increta group and percreta group.We analyzed the time from the start of surgery to baby delivery and the anesthetic technique.Results: The accreta group included 49 cases,the increta group 33 cases,and the percreta group 14 cases.The average time from the start of surgery to fetus delivery in the three groups were (6.7±3.0) min,(7.2±4.6) min,and (11.9±4.9) min,and the percreta group was significantly different from the accreta group and the increta group (P<0.05).There were significant differences among the three groups in anesthetic choices (P<0.001): in the accreta group,45 cases (91.8％) underwent spinal anesthesia,2 cases (4.1％) underwent general anesthesia,and 2 cases (4.1％) were converted to general anesthesia after spinal anesthesia during the operation;in the increta group,22 cases (66.7％) underwent spinal anesthesia,4 cases (12.1％) underwent general anesthesia,and 7 cases(21.2％) were converted to general anesthesia after spinal anesthesia;in the percreta group,2 cases (14.3％) underwent spinal anesthesia,2 cases (14.3％) underwent general anesthesia,and 10 cases (71.4％) were converted to general anesthesia after spinal anesthesia.Conclusion: Spinal anesthesia can be used as the first choice of cesarean section complicated with placenta implantation and general anesthesia should be considered in placenta percreta.

[Objective]To analyze the advantages of transparent cap assisted endoscopy in the diagnosis and treatment of duode-nal diseases.[Methods]From September 2014 to December 2015,62 cases with suspicious duodenal diseases in the endoscopy cen-ter of our hospital randomly divided into transparent cap group(n=31)and routine group(n=31)according to the time sequence. The visual field resolution,success rate of image capture and operating time were compared in 2 groups.[Results]Thirty cases in transparent cap group had clear visual field definition ,which was obviously higher than 9 cases in conventional group (96.8% vs 29%,P < 0.001). Twenty-three cases in transparent cap group and 8 cases in routine group were successfully captured(90.3% vs 25.8%,P < 0.001). The average operating time of the transparent cap group was significantly shorter than that of the conventional group(150+58 vs 95+36 seconds,P=0.004).[Conclusion]Transparent cap endoscope examination is more effective in the treat-ment of duodenal diseases,and the image capture is higher and the operation time is shorter.

Objective To explore the effect of early stage of comprehensive lung rehabilitation on cervical spinal cord injury in patients with mechanical ventilation.Methods The patients with cervical spinal cord injury admitted from January to December 2015 were selected as the control group which was treated with routine nursing measures.The patients with cervical spinal cord injury admitted from January to December 2016 were selected as the treatment group,which received early stage lung rehabilitation measures.We compared two groups of patients in the using time of breathing machine,the total length of hospital stay and pulmonary infection rate.Results The duration of mechanical ventilation and hospitalization days in the control group were(13.98±11.11),(25.10±16.98)d,which were higher than those in treatment group[(7.23±4.94),(16.26±6.41)d](P<0.05).The infection rates of control group and treatment group were 76.19％and 52.38％respectively,and the difference was significant(P<0.05).Conclusion In the early stages comprehensive pulmonary rehabilitation measures for mechanical ventilation in patients with cervical spinal injury can shorten the breathing machine use time and the total hospitalization days,and reduce pulmonary infection rate.

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.
