The new curriculum reform brought forth under the context of a new round of knowledge transformation has endowed teaching process with new meanings. A new type of teacher-student realationship characteristized with equality, democracy and dialogue is the precondition of successful teaching under the context of new curriculum reform; Knowledge and meaning reconstruction by the way of presetting and generating is the main feature of teaching process; The development process consisting of knowledge and life of both teachers and students is the ideal goal of new curriculum reform.

Objective To explore the related risk factors of esophageal variceal bleeding (BEV).Methods 69 liver cirrhosis patients with BEV were selected as the observation group.60 liver cirrhosis patients with no BEV were selected as the control group.The two groups were observed of age and the degree of esophageal varices,portal vein diameter (PVD),splenic vein diameter(SVD),thickness of spleen(SPT),the maximum depth of ascites fluid dark area (ASmax) and other related ultrasound index.Laboratory indexes were including prothrombin time (PT),serum total bilirubin (TBIL),serum albumin(ALB).Results The average age of the observation group was (52.71 ± 4.33) years old,which was higher than (46.83 ± 5.19) years old of the control group (t =4.08,P ＜0.05).The liver function(Child-pugh) Grade A and grade C in the observation group patients were 78.33％ and 0.00％,and compared with the control group,the difference was significant statistically (x2 =4.97,P ＜ 0.05).Esophageal varices with severe and mild of the observation group were 80.00％ and 1.67％,and compared with the control group,the difference was statistically significant(x2 =4.08,5.48,P ＜0.05).RC of the observation group was 78.33％,which was higher than 30.43％ of the control group(x2 =5.11,P ＜ 0.05).PVD,SVD,SPT and ASmax of the observation group were (16.05 ±3.14)mm,(11.24 ±3.21)mm,(46.90 ±6.26)mm and (57.91 ±6.11)mm,respectively,and compared with the control group,the differences were significant statistically (t =4.37,6.12,5.18,7.22,all P ＜ 0.05).PT of the observation group was (17.66 ± 2.08) s,which was higher than (13.93 ± 1.67) s of the control group (t =4.75,P ＜0.05).TBIL of the observation group was (172.63 ± 16.50) μmol/L,which was higher than (138.44 ± 12.71) μmol/L of the control group(t =5.44,P ＜ 0.05).ALB of the observation group patients was (27.36 ± 3.44) g/L,which was lower than (30.85 ± 2.75) g/L of the control group(t =7.09,P ＜ 0.05).Conclusion Age,liver function,PT and RC,PT,ASmax,PVD were related risk factors of patients with BEV.

Objective The present study aimed at the effect observation of vocal polyps treated with CO2 laser and laryngeal microsurgery. Methods The subjects were 60 patients, 30 were treated by CO2 laser and 30 by laryngeal microsurgery. A set of tests had been routinely used for vocal polyp patients in this study. The tests included(1) indirect laryngoscopic examination,(2)voice analysis: PPQ(pitch perturbation quotient), APQ(amplitude perturbation quotient), H/N(harmonics to noise ratio).(3)psychoacoustic evaluation: GRBAS method: Grade(G), Rough(R), Breathy(B), Asthenic(A), Strained(S). Results After operation, the recovery time of vocal cord for CO2 laser treated group was longer than that in the laryngeal microsurgery group. The acoustic parameters PPQ for CO2 laser group were larger than that in the laryngeal microsurgery group, moreover H/N values were smaller than that in laryngeal microsurgery group. The psychoacoustic evaluation for CO2 laser group was rough and strained, and for laryngeal microsurgery group was only rough. Conclusion The curative effect of laryngeal microsurgery is definite. Microsurgery is better than CO2 laser when recovery time and vocal function improvement are considered.

In the second half of 2016,the U.S. Food and Drug Administration(FDA)approved 7 new molecular entities and 3 new Biologic License Application(BLA), the lowest number in recent years. According to the prescription information for profes-sionals,this article introduced the description,mechanism of action and clinical studies and briefly describes the boxed warning,indi-cations and usage,dosage and administration,dosage form and strength,contraindications,warning and precautions,adverse reac-tions,drug interaction and the use in the special population.

In the Qing Dynasty,TANG Rong-chuan holded that 'qi blocked by blood would result in pain,and blood vaporized by qi would change into pus'.Take the surgical disease for example,pathogens of sore would be easily expelled by vigorous qi,on the contrary,if qi was deficient the pathogens of sore would be hardly expelled.Qi was water,qi reached so water reached.So the blood changed into pus which liked water-shape in terms of qi.Wound would maturate after was touched with water.Water was the essence of qi.So,blood stasis would transform into sore when it was influenced by qi.Whereas,the blood stasis was still blood without the influence of qi.Blood obeyed to qi,qi controlled blood flow.So,in clinic,the blood disease should be treated by regulating qi.Qi and blood played important role in the occurrence,development,prognosis and the treatment of the sore disease.

AIM: To investigate the possible role of P97 in non - transferrin bound iron uptake by rabbit reticulocytes. METHODS: The iron uptake were measured by the method of radioisotope (5gFe). RESULTS: (1) Only PI - PLC treatment had no apparent effect on iron uptake by reticulocytes (P > 0.05); (2) Reticulocytes, pretreated by pronase and then by PI - PLC, give a significant decrease in iron uptake in cytosol and in hemne ( P < 0.01). CONCLUSION: The results support the possibility that P97 might be able to be expressed on the membrane of reticulocytes and plays a role in non - transferrin bound iron uptake by this type of cells in the rabbit.

ObjectiveTo evaluate the effect of laparoscope and open repair on treating upper gastrointestinal(UGI) ulcer perforation.MethodsRetrospective analysis was performed in consecutive series of 143 patients undergoing UGI ulcer perforation repairing.Among the total 143 patients,98 cases underwent laparoscope repair(laparoscope group),45 cases were with open repair (open group).The operation methods included either simple interrupted suture or pedicled omental patch.Postoperative management of triple therapy included proton pump inhibitor,β -lactam antibiotics and arilin was conducted.Therapeutic effects were compared between two groups.ResultsOperating time in laparoscope group was significantly longer than that in open group [ ( 83.88 ± 19.67 ) min vs.( 63.33 ± 12.06) min,P ＜ 0.01 ].Time of passage of gas by anus,hospital stay,cost of hospitalization and postoperative dosage of opiates in laparoscope group were significantly lower than those in open group [ (29.45 ± 9.24) h vs.( 46.40 ± 49.21 )h,(6.92 ± 1.06) d vs.(7.71 ± 2.48 ) d,(6929.39 ± 832.40) yuan vs.(7546.67 ± 1393.92) yuan,(5.7 ±8.3 ) mg vs.( 10.9 ± 9.5 ) mg,P＜ 0.01 ].There was no significant difference between two groups in perforated diameter,perforated position and flushing dose of abdominal cavity (P＞ 0.05 ).The rate of complication was 14.29％ (14/98) in laparoscope group,while 26.67％ (12/45) in open group,there was no significant difference between two groups (P＞ 0.05 ).ConclusionsLaparoscope repair of UGI ulcer perforation is a safe and feasible procedure compared with open repair.Although operating time of laparoscope repair is longer than open repair,the rate of complication does not increase.
