Choosing a suitable textbook is the most important part to ensure the quality of in-ternational students' education. By comparing the advantages and disadvantages of English textbooks, domestic publishing textbooks and institutions self-made teaching materials, and combining with inter-national students' textbooks usage and investigation, we fine problems such as students' lower satisfac-tion of textbooks and better evaluation in original English textbooks than the domestic publishing text-books and college self-made teaching materials, so we advocate that we should select a good textbook, strengthen the construction of teachers and teaching materials, offer special medicine courses, establish an effective network teaching platform and attach importance to students' feedback.

Objective To investigate the ideal methods for correction of lower eyelid retraction by lateral canthal anchoring.Methods The authors retrospectively reviewed the records of 126 patients(207 eyelids) operated on between June 1999 and 2005 by one senior surgeon.The age of the patients ranged from 28 to 72 years(mean,46 years).Transcanrhal canthopexy was used in 20 patients(33 eyes);The 3 mm tarsal strip procedure was used in 35 patients(57 eyes);Transcanrhal canthopexy combined with Hamra's lower blepharoplasty was used in 26 patients(45 eyes).The tarsal strip procedure combined with Hamra's procedure was used in 45 patients(72 eyes).75 patients(123 eyes) were followed up for 6～12 months.Mean follow-up time was 8 months. Results Of them,125 patients were uniformly satisfied with their cosmetic and functional outcome at last follow-up;one patient had undercorrection of retraction.There were no major complications and only one minor complications(corneal irritation from graft sutures),which resolved in the early follow-up period.Conclusions The lateral canthal anchoring is an effective,aesthetic,and functional treatment for moderate to severe lower eyelid retraction resulting from multiple causes.This procedure is associated with predictable results,a low morbidity rate,and high patient satisfaction.

Objective To investigate the expression level and clinical significance of serum IL-18 and MCP-1 in patients with Chronic Obstructive Pulmonary Disease(COPD).Methods Serum IL-18 and MCP-1 levels were measured in healthy people( control group,30 cases) and in patients with COPD (acute stage group and stable stage group,30 cases in each group).At the same time,the level of serum CRP and forced expiratory volume in one second ( FEV1 ),the forced expiratory volume in one second/forced vital capacity ( FEV1/FVC％ ) were tested in the three groups.The variation.of the level of serum IL-18 and MCP-1 and the correlation between these index with lung function and CRP were analyzed.Results The levels of serum IL-18 and MCP-1 in acute stage group ( IL-18 [ 69.29 ± 16.14 ] ng/L,MCP-1 [ 123.95 ± 32.06 ] ng/L) were significantly higher than those in stable stage group ( IL-18 [ 53.15 ± 14.74 ] ng/L,MCP-1 [ 96.46 ± 18.24 ] ng/L) ( F =10.975,P ＜0.01 ),and also significantly higher than those in control group ( IL-18 [ 37.53 ± 14.55 ] ng/L,MCP-1 [60.86 ± 17.26] ng/L) ( F =18.101,P ＜ 0.01 ).In acute stage group,positive correlations were obtained among the level of serum IL-18,MCP-1 and CRP ( r =0.688,P ＜ 0.05 ; r =0.663,P ＜ 0.05 ; r =0.825,P ＜0.01 ),and they were correlated negatively with FEV1 and FEV1/FVC％ ( r =- 0.732,P ＜ 0.01 ;r =- 0.586,P ＜0.05 ).In stable stage group,the level of serum MCP-1 was correlated positively with the level of IL-18( r =0.674,P ＜ 0.05 ) and with the level of CRP ( r =0.719,P ＜ 0.05 ),but it was correlated negatively with FEV1 and FEV1/FVC％ ( r =-0.512,P ＜ 0.05 ;r =-0.557,P ＜ 0.05 ).Conclusion The serum IL-18 and MCP-1may be one of the inflammation markers in patients with COPD and may be associated with airway inflammation and limited airflow.

Objective To analyze and evaluate the efficacy of intramedullary interlocking nail in the treatment of long bone fractures.Methods From July 1997 to October 1999,100 cases of long bone fractures were treated intramedullary interlocking nail,including 25 fractures of tibia and fibula at middle site tibia,35 at middle-lower,31 middle femoral,9 middle-lower of femoral.Results The period from 3 to 19 months with an average of 13 months for followed-up.The average fracture healing time was 14 weeks.According to Johnenand-Wruh evaluation method,98 of 100 patients(98%) were excellent osteosythesis,one case was good and only one case was bad.Conclusions The treatment of long bone fractures with intramedullary interlocking nail is a good way.It has high healing rate,and pathologic rigidity of joint movement is fewer.But the method has some limits for operative indication and its special complications also to be explored further.

Objective To measure the serum levels of endothelin-1 (ET-1) and transforming growth factor-β(TGF-β) in the newborns with respiratory distress and investigate its clinical significance. Methods Newborns with respiratory distress hospitalized into the Newborn Intensive Care Unit were included. The serum levels of ET-1 and TGF-β were all detected with ELISA in the first six hours,3,7,14 and 28 days after birth. Results The highest levels of ln ( 1 + ET-1 ) and ln ( 1 + TGF-β) were obtained from newborns with diagnosis as meconium aspiration syndrome ( 1.95 ± 1.02) ng/L and ( 1.51 ±0.99) ng/L,respectively) in the samples obtained in the first six hours after birth, and these were statistically different from those of the control group ( P ＜ 0. 05 ). Following were obtained for newborns with respiratory distress syndrome ( ( 1.52 ± 0.74 ) ng/L and ( 1.13 ± 0. 48 ) ng/L, t = 2.28,2. 13,respectively). After oxygen treatment, ET-1 levels obtained in the first six hours of life decreased gradually in the following days (P ＜0.05 ). Conclusions The measurements of ET-1 and TGF-β levels will help in differentiating diagnosis of the respiratory distress of newborns. The ET-1 levels will help to assess the therapy effectiveness and prognosis.

Objective To investigate the dynamic changes and its clinical significance of serum glial fibrillary acidic protein (GFAP) content in patients with acute cerebral infarction.Methods We consecutively collected 47 cases of acute cerebral infarction. The serum specimens were gathered on admission, at 3rd and 5th day after onset. The serum levels of GFAP were compared according to Oxford community stroke project (OCSP) and CT classifications, and the relationships between serum GFAP levels and patient's condition and prognosis of disease were analyzed. Results Serum GFAP level in TACI group was significantly higher than those in control group and other 3 subtype groups within 48 h of onset, and continuously increased at 3rd day and 5th day. The GFAP level in PACI group reached peak at 3rd day and returned nearly to normal level at 5th day. There was no significant difference between POCI group and LACI group and control group. Serum levels of GFAP were significantly higher in large infarcts and in corticosubcortical infarcts. GFAP level was related with score of NIHSS (r=0.410, P

Objective To study the mechanism of the extract of three kinds of Chinese herbs in treating psoriasis.Methods Three kinds of Chinese herbs(coptis root,patience dock root and atratylodes rhizome) were extracted.With the culture of human transformed keratinocyte cell line colo-16 cells as a model,the single and compound effects on the growth of KC were studied before and after stimulated by TNF-?.Results The single and compound extract of three Chinese herbs could restrain the proliferation of KC before and after stimulated by TNF-?.The effect was more remarkable than the compared methotrexate and cyclosporin A(P

The hemodynamic mechanism has been considered to be the main factor related to the cerebral aneurismal growth and rupture. Virtual numerical research has become an important method for the study of cerebral aneurismal hemodynamics, which lead to a deep insight into the field of hemodynamic mechanism.We reviewed the correlative researches in this field during recent years and made a summarization concerning about, the relationship between intra-aneurysmal hemodynamics like velocity,wall tangential stress and pressure field under variable conditions and the biological behaviors such as growth and rupture of aneurysms; and further discussion on the topic of clinical application.
