The current situation is that the study of blood system diseases is difficult, and the students lack both the initiative and enthusiasm to learn. Clinical teachers' energy is limited because of other clini-cal, management and research roles, so the quality of teaching varies greatly. Meanwhile, teaching quality has nothing to do with personal reviews. Furthermore, the relationship between doctors and patients is in trouble in current medical environment. All of these above affect the quality of clinical practice in hematology department. Aiming at these problems, we improve the teaching quality significantly by raising the students' interests, enhancing their initiative, improving teachers' teaching level and enthusiasm, carrying out the in-ternship system, and strictly enforce the elimination system.

Objective To analyses the effect of Buzhong Yiqi Decoction on the expression of Caspase-3 in human lung adenocarcinoma cells (A 549) tumor-bearing mice’spleen. Method 24 BALB/c mice were randomly divided into the control group(given saline),low-dose and high-dose Buzhong Yiqi Decoction groups,cisplatin(DDP)group;Buzhong Yiqi Decoction was administered twice daily for 10 days consecutively and DDP was administered once daily for 3 days consecutively, after 15 days was the spleens of all tumor-bearing mice were obtained.The expression of Caspase-3 protein and Caspase-3 mRNA in every group were detected by immunohistochemical method seperately and polymerase chain reaction method seperately. Results Compared with control group,the result of immunohistochemistry showed that the expression of the Caspase-3 protein in Buzhong Yiqi Decoction low-dose group and high-dose group were both ssignificantly increased (P<0.05). The differences hetween DDP group and control group was not significant, but the differences between DDP sroup and Buzhong Yigi Decoction Low-dose sroup and hishdoe group were significant (P<0.05, P<0.01).The result of RFPCR was accordance with the result of immunohisto chemistry. Conclusion Buzhong Yiqi Decoction can increase the expression of Caspase-3 protein in A549 ctumor-bearing mice’spleen,and promote the Caspase-3’s inducing effect on tumor cell apoptosis.

The clinical probation is an important part of medical education, which is also a bridge from theoretical learning to clinic practice. To improve the quality of clinical probation teaching of hematology department, multiple teaching activities have been carried out, including full preparation before teaching, creating better medical environment, arousing enthusiasm, tralning the physician-patient communication ability and strengthening operating skill of the students. Good study effect has been achieved.

To elaborate the the main thoughts and treatment experience of dampness in Medical Origin and Insights, written by Zhang Yuansu. Dampness-resolving drugs and prescriptions were comprehensively and carefully summarized and analyzed. Strengthening spleen and stomach was viewed as guideline, and Rhizoma Atractylodis Macrocephalae as well as its brilliant combinations, was taken as preferred drug to resolve dampness, with the help of brilliant combinations. Emphasis was laid on the treatment according to patterns, positions and characters of diseases. Medical Origin and Insights, essence collector of Zhang’s thoughts, has enriched and developed basic traditional Chinese medicine theories and practices. Thus, it showed guiding significance on dampness treatments.

Objective To compare the effects of sevoflurane versus propofol on a tourniquet-induced lower extremity ischemia-reperfusion (I/R) injury in patients undergoing orthopedic operation.Methods Fifty-four ASA Ⅰ or Ⅱ patients,aged 18-64 yr,weighing 44-85 kg,scheduled for elective orthopedic operation,were randomly assigned into 3 groups (n =18 each)∶ control group (group C),propofol group (group P) and sevoflurane group (group S).After lumbar plexus-sciatic nerve block,the laryngeal mask airway insertion was facilitated with propofol 2-4 mg/kg and anesthesia was maintained with infusion of propofol at 2-4 mg· kg-1 · h-1 during operation in group P.In group S,8 ％ sevoflurane was inhaled,the laryngeal mask airway was inserted and anesthesia was maintained with inhalation of 2％ sevoflurane during operation.A tourniquet was applied and inflated (300 mm Hg)during 15-20 min after administration of propofol or sevoflurane in groups P and S,and a tourniquet was also applied at the same time point in group C.The tourniquet was released at the end of operation.Postoperative analgesia was performed with oral meloxicam or intramuscular pethidine and VAS score was maintained ＜ 3.Blood samples were taken after admission to the operating room (T1) and 30 min after tourniquet release (T2) to determine the plasma concentrations of MDA and TNF-α.The changing rate of MDA and TNF-α concentrations was calculated.The tourniquet-related adverse events and amount of analgesics consumed within 24 h after operation were recorded.Results No tourniquet-related adverse events occurred in all the patients.Compared with group C,the plasma concentrations of MDA and TNF-α and changing rate were significantly decreased at T2 in groups P and S (P ＜ 0.05).There were no significant differences in the plasma concentrations of MDA and TNF-α and changing rate between group S and group P (P ＞ 0.05).Compared with the baseline value at T1,no significant change was found in the plasma concentrations of MDA and TNF-α at T2 in groups P and S (P ＞ 0.05),and the plasma concentrations of MDA and TNF-α were significantly increased at T2 in group C (P ＜ 0.05).There was no significant difference in the amount of analgesics consumed within 24 h after operation between the three groups (P ＞ 0.05).Conclusion Both sevoflurane and propofol can reduce a tourniquet-induced lower extremity I/R injury in patients undergoing orthopedic operation and the efficacy is comparable.

Objective To reduce the execution time of neural network training. Methods Parallel particle swarm optimization algorithm based on master-slave model is proposed to train radial basis function neural networks, which is implemented on a cluster using MPI libraries for inter-process communication. Results High speed-up factor is achieved and execution time is reduced greatly. On the other hand, the resulting neural network has good classification accuracy not only on training sets but also on test sets. Conclusion Since the fitness evaluation is intensive, parallel particle swarm optimization shows great advantages to speed up neural network training.

The treatment of myopic amblyopia and myopic anisometropic amblyopia is difficult and usually resultless and it has been the obstacle of amblyopic treatment. Corneal contact lens, corneal refractive surgery and phakic intraocular lens as new methods can significantly improve visual acuity of patients with high myopic amblopia and myopic anisometorpic ambyopia. For correcting myopia and myopic anisometropic amblyopia it provides a new method. This paper discusses the availibility and safty of above methods for the treatment of myopic amblyopia and myopic anisometropic amblyopia.

A case of large artificial teeth in hypopharynx and upper esophagus was reported. Physical signs of laryngeal obstruction were detected. CT showed foreign body in right pyriform sinus. Acute tracheotomy was performed before removal of the large foreign body with the help of esophagoscope and mouth-gag.
