In recent studies,obesity is a risk factor for a variety of cancers,including breast cancer and colorectal cancer.Obesity can regulate the tumorigenesis and development of cancer by some factors,such as insulin and insulin-like growth factor-1 (IGF-1),leptin,fat cytokines and hormones.Understanding the relationship between obesity and cancer can provide a new perspective for the prevention and treatment of cancer.

Objective To investigate the effect of donepezil hydrochloride on the expression of Calpain Ⅰ-Cdk5/p25 pathway in the hippocampal CA1 area by cerebral ischemia and reperfusion in mice.Methods Mice were divided into model group,sham-operated group and donepezil-treated group.The expression of Calpain Ⅰ in hippocampal CA1 area was measured by immunohistochemistry staining respectively at 4,6 and 8 weeks post cerebral ischemia and reperfusion.Western blot was used to evaluate Cdk5 and p25 protein expression.Results The abilities of learning and memory performance was damaged significantly at 4,6 and 8 weeks after surgery compared to sham-operated group (P＜ 0.05).The expression of Calpain Ⅰ of model group were (0.098 ± 0.009),(0.129 ±0.01),(0.116 ± 0.01),which were higher than that of sham-operated group (0.03 ± 0.003),(0.031 ± 0.003),(0.029 ±0.003) and there was significant difference (P ＜ 0.05).The expression of Cdk5 in model group was (0.54 ± 0.05),(0.73 ± 0.07),(0.7 ± 0.06),which were higher than that of sham-operated group (0.23 ±0.02),(0.31 ± 0.02),(0.33 ± 0.02) and there was significant difference (P ＜ 0.05).The expression of p25 in model group was (0.44 ± 0.04),(0.51 ± 0.04),(0.55 ± 0.06),which were higher than that of sham-operated group(0.19 ± 0.02),(0.24 ± 0.02),(0.2 ± 0.02) and there was significant difference (P ＜ 0.05).The expression of Calpain Ⅰ of donepezil-treated group was (0.041 ± 0.004),(0.054 ± 0.004),(0.046 ± 0.003),which were lower than that of model group.The expression of Cdk5 was (0.28 ± 0.02),(0.33 ± 0.03),(0.38 ± 0.02),and expression of p25 was (0.26 ± 0.02),(0.25 ± 0.03),(0.21 ± 0.02),which were lower than that of model group respectively(P ＜ 0.05).Conclusion Donepezil hydrochloride probably improve the learning and memory abilities by reducing the expression of Calpain Ⅰ and Cdk5/p25.

With the process of internalization of traditional Chinese medicine(TCM) accelerating increasely, intensive study on international educational reform of TCM is significant. This article elaborates importance of international educational reform of TCM from development situation of Tianjin University of Traditional Chinese Medicine, combined with regional characteristics, find that intensifying the reform and expanding the opening up of international education of TCM is an Important Channel of international development of Tianjin, a reflection of national willpower, a corollary of adapting to the development trend of the economic globalization and an inevitable requirement and powerful guarantee of internalization of TCM. Therefore, we hold that international educational reform of is imperative to achieve the internalization of TCM.

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.

Clinical practice training is a interim curriculum of basic courses and clinical courses, medical university and hospital, which is an important part of medical education system. Clinical practice training teachers, as the main subject of teaching activity, is a key in guaranteeing a better teaching quality. Therefore, we should attach great importance to the construction of clinical practice training teachers, renewal of the idea of clinical practice training, training system and measures of clinical practice training teachers and the improvement of the management of clinical practice training

OBJECTIVE: To explore the application of double pedicle blood supply pectoralis major myocutaneous flap in reconstruction of laryngeal and hypo pharyngeal defect after carcinoma resection. METHOD: All the patients received initial treatment. Pectoralis major myocutaneous flap was Applied in one-stage reconstruction in 22 cases of laryngocarcinoma and hypopharyngeal carcinoma with post-operation defect. During operation, pectoral branches of thoracoacromial vessels and branch of lateral thoracic vessels were reserved and prepared to be double pedicle vessel fascia bundle without muscle at the beginning part, rearched to defect area through subclavian tunnel. After operation, it is necessary to closely observe the subcutaneous swelling, quantity and color of the drain and others of neck surgery area to exclude the occurrence of surgical hematoma. When there is suspicion, do timely exploration. RESULT: Pectoralis major myocutaneous flaps of 22 patients were all survived. Pharyngeal fistula occurred in 2 cases and was cured by change of dressing. Twenty-one cases received radiotherapy after operation without secondary flap necrosis. After follow-up of 6 months to 24 months, one case of roll repairment of circumferential defect in cervical esophagus,found to have anastomotic stenosis 8 months after radiotherapy and then underwent gastrostomy treatment,the other 21 cases showed good recovery of swallowing function. Among 13 cases with laryngeal function reserved, only 1 case wearing tube and the extubation rate was 92.3% without communication barriers, no patient died in the short follow-up period. CONCLUSION For double pedicle blood supply pectoralis major nyocutaneous flap, blood supply are fully guaranteed and does not require complicated equipment to observe and monitor the flap blood supply after operation, it is important to exclude factors that may lead to muscular flap necrosis to ensure the survival of pectoralis major myocutaneous flap.
