In order to improve teaching lever and explore teaching approach, the feasibility study on the combination of the problembased learning method CPBL) and the lecture-based learning method (LBL) was conducted in the teaching of Acupuncture and Moxibustion. The 2010 undergraduates in the major of clinical integrated Chinese and western medicine of five years were randomized into a PBL and LBL group and a LEL group. In the first semester, according to the basic teaching requirement, LBL was used to accomplish the teaching of basic theory. In the internship teaching section, the different teaching method was applied. In the PBL and LEL group, PEL was used, and in the LBL group, LBL was given. At the end of semester, the examination results of the theory learning and medical cases learning were evaluated. The questionnaire was summarized in the teachers and students. The final examination result of theory learning was not different significantly between the two groups (P >0. 05), but the result of medical cases learning in the PEL and LEL group was better than that in LEL group (84. 47±10. 72 vs 76. 00±9. 97, P<0. 05). The questionnaire for the students and teachers indicated that the result of PEL and LEL combined method was higher than that of LEL method (86. 27±8. 36 vs 56. 00±14. 59, P< 0. 01; 45. 89±3. 68 vs 36. 61±6. 41, P<0. 0l), indicating that the combined method of PBL and LEL is feasible in teaching of Acupuncture and Moxibustion and the teaching outcome is superior to the simple LBL, which provides the new approach to the teaching reform.

Objective TO investigate the application of Nutritional Risk Screening 2002 (NRS 2002) and nutrition support in critically ill patients.Methods Totally 172 adult critically ill patients with a hospital stay equal to or above 3 days were consecutively enrolled from a Beijing-hospital from September 2011 to December 2011.Nutrition support was evaluated on a daily basis.NRS 2002,body mass index (BMI),and Acute Physiology and Chronic Health Evalnation Ⅱ (APACHE Ⅱ) were applied to assess the nutritional risks and nutrition status within 24 hours after admission.Results Among all the patients,the rates of nutrition support were 39.5％ and 67.9％ on the 1st and 7th day respectively.The rate of parenteral nutrition (33.6％ ～ 39.5％) was higher than that of enteral nutrition (4.1％ ～ 16.0％).NRS 2002,APACHE Ⅱ score,and BMI showed that 160 patients (93.0％) required nutrition support,but only 103 patients (64.4％) actually received nutrition support,among whom 92 (89.3％) were supplied with nutrition support within 3 days after admission.Conclusions The application of nutrition support in critically ill patients is insufficient in this hospital.Nutrition support is typically provided within 3 days after admission.Parenteral nutrition remains the most common type of nutrition support.

The electromyography of the superior and inferior heads of lateral pterygoid muscle of 15 human subjects were recorded. It has been observed that marked active potential occurred in the superior head of the ipsilateral pterygoid muscle and the inferior head of the contralateral muscle during a one-side molar bite. Marked active Potential appeared in the superior head of the lateral pterygoid muscle during the closing movement of the jaw, whereas it appeared in the inferior head during the opening movement.It has not been confirmed that the lateral pterygoid muscle is an important protractor of the mandible, as only relatively weak active potential was recorded in the two heads of the muscles on both sides during the protraction of the jaw. Very marked active potential has been observed in the ipsilateral prenygoid muscle during the lateral movement of the mandible, while in the contralatenal superior head it occurred only slightly. The. above finding does not correspond to the descriptions found in current text-books.The two heads of the lateral pterygoid can therefonose considered as two functionally and structurally distinct muscles.

Objective To investigate the expression of stratum corneum chymotuptic enzyme (SCCE) and its significance in human cervical adenocarcinoma.Methods Immunohistochemistry was used to detect the expressions of SCCE,ER,CEA and Vimentin in tissues from the group of 45 cervical adenocarcinoma patients,group of 24 cervical glandular intraepithelial neoplasia (CGIN) patients and group of 24 normal cervical tissues.Results The expression of SCCE was 84.44 ％ (38/45),58.33 ％ (14/24) and 8.33 ％ (2/24) in 3 groups respectively.The SCCE expression from group of cervical adenocarcinoma were more significantly than that of normal cervical tissues (P ＜ 0.012 5),the expression of SCCE from group of CGIN were more significantly than that of normal cervical tissues (P ＜ 0.012 5),but there was no difference between the cervical adenocarcinoma and the CGIN on the expression of SCCE (P ＞ 0.012 5).Conclusion SCCE could be recommended as a new biomarker for the early screening cervical adenocarcinoma and as an additional marker for the prognosis of cervical adenocarcinoma.

As an important messenger molecule, NO exists in both peripheral and central nervous system (CNS). Recently, NO was proved to play a critical role in CNS, especially in synaptic plasticity. As a kind of retrograde messenger, it plays some roles in the induction and maintenance of LTP through activation of downstream pathway or molecules, such as NO-cGMP-PKG, ADPRT and C-FOS.

Protective effect of Chinese medicinal Lerbs against gastric stress injury was studied.The compound antioxidant prescription used was composed of ten herbs, each of which had proven antiperoxidation action. Bound-soaked rats were used as victims of stress injury. In the two groups of rats under protection of the "prescription and injection of salvia" the indexes of gastric mucosa injury were 8.50?2.31 and 19.00?4.25, LPO in serum were 10.74? 0.94 and 11.80? 1. 06nmol/ml respectively. Both were significantly decreased as compared with the control group (39.00? 6.50, LPO 19.06? 1. 10nmol/ml ). These results signified that the antioxidant medicinal herbs, especially in compounded form, may prevent gastric stress injury
