Intravascular large B cell lymphoma is a rare subtype of diffuse large B cell lymphoma. Abnormal proliferation of intravascular lymphoma cells is its pathological feature with aggressive clinical behavior such as easy invasive feature, rapid disease progression, poor prognosis and low survival rate. We review the progress in recent research on classification, diagnosis, treatment and prognosis of intravascular large B cell lymphoma.

Meridian, collateral and acupoints is the basic course of acupuncture and moxibustion and even is the core for training excellent acupuncture physician. Associated with the characters of international students, the writers had the preliminary exploration and practice on teaching this course. For the acupoint names, the international codes of acupoints and Chinese pinyin were applied in combination and the meanings of acupoint were explained to deepen the understanding of acupoints. For acupoint location, the international standards and classical medical works were combined and the experiences in acupoint location were introduced additionally to open the approach to acupoint location. For acupoint effect, the major functions and ancient medical cases were combined to improve the learning interests. For acupoint location practice, the demonstration by teachers was combined with practice and drawing of acupoints and meridians was supplemented to consolidate the foundational knowledge.

In order to obtain the normal gait for the prosthesis-carrier with the change of external environment and gait, we designed a model of dynamic ankle prosthesis and control system and introduced the strategy of central pattern generator (CPG) about the moving trail of dynamic ankle prosthesis. The dynamic parts, which are incorporated in the model of dynamic ankle prosthesis, provide power in order to have anthropic function and character. The tool of Matlab/simulink was used to simulate the strategy. The simulation results showed that the strategy of CPG learn- ing control in this study was effective and could track the reference trail rapidly and fit the moving trail of a person's normal limb. It can make the prosthetic timely regulation and action, enhance the prosthetic intelligence. It has im- portant practical value for intelligent prosthesis development based on this analysis of technology.

Objective:To observe the influence of methylprednisolone in the respiratory mechanical parameters in the elderly patients undergoing major surgeries with general anesthesia intubation after mechanical ventilation,and to investigate whether methylprednisolone can improve the respiratory system degenerative diseases and benefit the mechanical ventilation. Methods:Sixty patients undergoing elective line laparotomy were divided into experimental group and conrol group (n=30) according to their wishes.The patients in experimental group receieved intravenous injection of methylprednisolone 1 mL (40 mg) after endotracheal intubation,and the patients in control group receieved 1 mL intravenous saline water injection.The airway peak pressure (Ppeak), airway platform (Pplat), lung compliance (Compl), and airway resistance (Raw) of the patients in two groups were recorded at the time of immediately before administration and 10,20,30,40 min after administration.The arterial blood oxygen partial pressure(PaO2),arterial blood CO2 partial pressure(PaCO2),CO2 partial pressure at the end of breathe out(PetCO2) of the patients were detected at the time of immediately before administration and 20 min after administration.Results:Compared with before administration, the respiratory mechanics parameters of the patients in control group 10,20,30,40 min after administration had no statistically significant differences (P>0.05);the Comple of the patients in experimental group was singnificantly increased (P<0.05), and the Ppeak, Pplat,and Raw were significantly decreased (P<0.05).Compared with control group, the Compl of the patients in experiment group 10,20,30,and 40 min after administration were significantly increased (P<0.05),and the Ppeak, Pplat, and Raw were decreased (P<0.05).Compared with before administration,the PaO2,PaCO2,and PetCO2 of the patients in control group 20 min after administration had no significant differences(P>0.05);the PaCO2 and PetCO2 of the patients in experimental group 20 min after administration were decreased(P<0.05),and the PaO2 was increased(P<0.05).Compared with control group,the PaCO2 and PetCO2 of the patients in experimental group 20 min after administration were decreased(P<0.05),and the PaO2 was increased(P<0.05).Conclusion:Methylprednisolone can obviously reduce PaCO2,Peak, and Pplat and increase PaO2 and Compl;methylprednisolone has possibility in improving the adverse effects of degenerative disease of respiratory system on general anesthesia in the elderly patients.

Pulse-taking, as one of the four diagnostic methods of inspection, auscultation and olfaction, inquiry and pulse-taking, can fully embodies the characteristics of traditional Chinese medicine. Pulse-taking is the teaching key point for the international students. However, because the pulsetheory and literature is quite profound and abstract and there is a long distance between the class teaching and clinical practice, the teaching of pulse-taking is also the difficult point for the international students. Therefore, the pulse-taking teaching should focus on the interesting teaching, the culture of traditional Chinese medicine of pulse, image teaching and practice training.

Objective To investigate the efficiency and application value of CT-guided percutaneous puncture biopsy in the diagnosis of lung disease.Methods The clinical and imaging data of 60 patients with CT-guided percutaneous lung biopsy were analyzed retrospectively.Results Among all the 60 patients, 57 had finally to be proved by pathological diagnosis, including 47 primary lung cancer (21 squamous cell carcinoma, 18 adenocarcinoma, 3 small cell lung cancer and 5 bronchioloalveolar carcinoma), 7 metastatic lung cancer and 3 tuberculosis.In addition, 3 cases were chronic inflammation and did not make a definite diagnosis, in which 2 were proved to be caseous pneumonia and 1 was proved to be fungus infection by postoperative pathology.The successful rate of punctures,the diagnostic accuracy and the total complications rate of lung puncture biopsy in 60 cases was 100%, 95.0% and 21.7% [11.7% pneumothorax (7/60), 8.3% hemoptysis (5/60) and 1.7% needle bleeding(1/60)].Conclusion CT-guided percutaneous puncture biopsy is a safe, accurate and significant clinical method in the diagnosis and differential diagnosis of lung lesions.
