The research of esophageal target is a difficult spot in the precise radiotherapy and the target mobility has an important effect for the radiotherapy of esophageal cancer.By different breathing control techniques,controlling the patient's respiratory may narrow target mobility so as to improve the accuracy of radiotherapy.But the present studies of the movement range of esophageal cancer with the respiratory control technologies have not come to a consistent standard.The area shape and position change of esophageal cancer target is a key problem that needs to be solved in the esophageal precise radiotherapy.

As a transcriptional repressor,Bmi-1 is a member of polyeomb group gene family.It may play an important role in self-renewal ability and proliferation of stem cell.At present,studies show that Bmi-1 is highly expressed in a variety of solid tumors,which can be regarded as one of the markers of cancer stem cells and has a close relation to the cancer development and progression and radiation resistance.It will provide an important target gene for the treatment of malignant tumors.

Previous research rcvealed that distortion is detected in transient voltage signal recorded with traditional patch clamp amplifier under current clamp mode, which is essentially resulted by electronic design of the headstage of the patch clamp. A new kind of headstage is designed to modify the defect, the circuit of which not only measures the transient potentials as the classical voltage follower does but also is quite suitable for the standard voltage-clamp mode. Furthermore, the technique of voltage-clamp-controlled current-clamp is applied for modifying the conventional patch-clamp amplifier, the variable low-pass filter is added into the circuit to reduce the response speed of voltage-clamp module, thus the transient potentials changes can be measured while membrane potential is kept at a constant value. Bridge balance circuitry is designed to eliminate the voltage drop while the variable current injected into the electrode. And fast capacitance compensation stage of conventional PCA is modified to nentralize the capacitance and accelerate system response speed for current-clamp mode. The experirnental results on cell model demonstrate that modified PCA meets the rcquirement of monitoring transient potential changes in electrophysiology research.

Objective: To analyze the risk factors on acute respiratory dysfunction caused death in patients after type A aortic dissection surgery.
Methods: A total of 223 patients who received aorta replacement surgery in our hospital from 2010-01 to 2012-12 were retrospectively studied. 80 patients suffered from post-operative acute respiratory dysfunction including 61 male and 19 female with the mean age of (49.2 ± 11.6) years. Those patients were divided into 2 groups as Death group, n=18 and Survival group, n=62. We analyzed the most relevant risk factors for death, such as gender, age, histories of smoking, diabetes, hypertension, Marfan syndrome;pre-operative acute or chronic dissection, hypoxemia, mal-perfusion, LVEDD and LVEF;CPB time, aortic-clamping time;post-operative ICU retention time, mechanical ventilation time, permanent neurologic dysfunction, pulmonary infection, MACE, renal failure, hypohepatia, septicemia and wound mal-healing, et al.
Results: The early post-operative (< 3 days) respiratory dysfunction rate was 35.8% and the mortality was 22.5%(18/80). The relevant risk factors of death included female gender (P=0.019), haemorrhage (P<0.01), mechanical ventilation time (P=0.011), permanent neurologic dysfunction (P=0.013), pulmonary infection (P=0.001), MACE (P=0.022), renal failure (P<0.01), hypohepatia (P<0.01) and septicemia (P=0.001). Female gender and renal failure were the independent risk factors for respiratory dysfunction caused death in patients after type A aortic dissection surgery.
Conclusion: The occurrence and mortality were high in patients after type A aortic dissection surgery especially in those with female gender and post-operative renal failure.

Vascular complications after liver transplantation can seriously threaten the survival of patients.In the preoperative assessment and postoperative monitoring of patients' vascular conditions,although the digital subtraction angiography (DSA) is the golden standard for vascular lesion diagnosis,but not the first choice due to traumatic lesions.In some clinical circumstances,DSA can only be used when Doppler ultrasound,spiral CT,and MRI are not applicable,and in most cases DSA is used for treatment rather than diagnosis.This article reviewed the current interventional treatment of vascular complications to stress the important role of DSA in diagnosis and treatment of related complications after liver transplantation.
