Objective To investigate the mastery of clinical students' doctor-patient communi-cation skills and to assess the teaching effectiveness about the doctor-patient communication, and then propose some improvement ideas. Methods We conducted a study in students of clinical medicine of Nanjing Medical University in Grade 2009, using Objective Structured Clinical Examination (OSCE) after internship, which included graduation assessment of doctor-patient communication skills. Then we analyzed the doctor-patient communication skills and related scores of students trained in different clinical medical programs. Results The average score of doctor-patient communication skills of 549 students was (82.72±4.23), of which, the average score of 329 five-year students of clinical medicine was (81.88±4.23) and the average score of seven-year students was (83.96±3.91) in. The average score of seven-year students of clinical medicine was significantly higher than five-year students (P=0.000). Moreover, there was a significant positive correlation between the total score of OSCE and the score of doctor-patient communication skills in both five-year and seven-year students of clinical medicine (five year program students' score correlation coefficient was 0.520, P=0.000;seven year pro-gram students' score correlation coefficient 0.416, P=0.000). Conclusion The teaching effectiveness of doctor-patient communication has proved to be quite effective, and it is definitely of great significance in improving clinical students' doctor-patient communication skills. The score of the assessment of the doctor-patient communication reflects not only the training effectiveness of the communication skills, but also the comprehensive capacity.

Objective To investigate the prevalence,radiological features and the association between HRCT changes and different diseases or clinical features in interstitial lung disease(ILD)caused by diffuse connective tissue diseases(CTD).Methods Retrospective analysis was performed based on the medical records of 412 in-patients with the diagnosis of diffuse connective tissue diseases from June 2003 to June 2005 in our hospital.268 cases were SLE,83 cases were SS,40 cases were DM/PM,21 cases were SSe.All patients had chest X-ray and the suspected cases had HRCT exam.The distribution of ILD among different diffuse CTD.the appearance between X-ray and HRCT appearances were compared.The correlation among HRCT appearance,different diseases and clinical features was studied.Results①In the 412 cases of CTD,ILD de- tected by HRCT was 9.7%(40 case in total),3,9% by X-ray.Among the 40 cases,DM/PM had the highest rate of ILD(25%),23.8% in SS,9.6% in SS and 6.3% in SLE.②The consensus rate between HRCT and X-ray was 40%.The rate of mis-diagnosis of ILD was 60% by X-ray.③The changes of interstitial involvement de- tected by HRCT were:ground glass change(41.0%),consolidation(32.8%),reticular change(16.4%)and hon- eycomb change(9.8%).The concomitant presence of two of the above changes were very common.④More level respiratory symptoms such as cough,panting,chest distress and chest pain and high level of complement were observed in patients with ground glass and consolidation changes,while high CRP level was seen in patients with consolidation and honeycomb changes(P

Objective:To investigate the protective effects of Panax notoginseng on myocardial ischemia injury in dogs and study the spectrum-activity relationship of Panax notoginseng. Methods:Firstly, the HPLC fingerprint analytical method for Panax notogin-seng was established, and then the dog model of acute myocardial ischemia was established by left anterior descending coronary liga-tion. Bivariate correlation analysis and multivariate regression analysis were used to correlate the spectrum-activity relationship between the fingerprints and the anti-myocardial ischaemia activity, and the spectrum-activity relationship and efficacy material foundation of Panax notoginseng were determined. Results:The main effective components were Ginseng saponin Rg1 and Rb1 and notoginseng sapo-nins R1 etc. Notoginseng saponins R1 could significantly inhibit the increase of serum lactate, and ginseng saponin Rg1 could inhibit the increase of FFA in serum, which was the main component in Panax notoginseng for the treatment of myocardial ischemia. Conclusion:The effective substances in Panax notoginseng are obtained by investigating the relationship between the spectrum and efficiency, and a new method for the evaluation of spectrum-activity relationship for Panax notoginseng is established. It can objectively reflect the inher-ent quality of the drug and provide a new strategy for the further research of traditional Chinese medicines.

Objective To study the protein components of the secretion of the proximal trunk of transected peripheral nerve and the effect of the secretion on the growth of motor neuron.Methods After the sciatic nerves of rats were transected, the proximal trunk secretion collecting compartment (P-SCC), distal trunk SCC (D-SCC) and (proximal) plus distal trunk SCC (PD-SCC) were set up. The protein components of the solution in the 3 types SCC were analyzed by two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and mass spectrum. And the effect of 3 kinds solution on the growth of motor neuron was tested by the motor neuron culture respectively. (Results) All the P-SCC, D-SCC and PD-SCC were filled with light yellow, clear fluids. The protein (concentration) was (5.45?1.2)mg/ml,(3.87?0.7)mg/ml and (5.68?1.5)mg/ml in the solution of PD-SCC, P-SCC and D-SCC (respectively). The protein patterns of the 3 solution were similar, and the detected (protein) spots were 1098?34,985?47 and 1021?36 spots in the solution of P+D-SCC, P-SCC and D-SCC (respectively). Most of the protein spots (distributed) in the rangs of MV 25-90KD and PH 4-8. The results of motor neuron culture demonstrate that the number of survival cells, cell area, neurite length and OD value of experimental groups(including mix group, (proximal) group and distal group) are generally higher than control group. But there is no obvious difference between the three experimental groups. Conclusions (1)The proximal trunk of transected sciatic nerve had the similar secretive ability as the distal nerve trunk.(2)(Protein) image of the 3 kinds of SCC solution showed that proteins from the three SCC solution were homologous. (3)All the 3 kinds of SCC solution could promote the growth and activity of motor neuron, and there was no difference in function between P-SCC and D-SCC solution.

AIM:To compare the effect of three types of pterygium surgery and on tear film in patients with type 2 diabetes mellitus. ·METHODS:A total of 102 patients ( 102 eyes ) with pterygium combined with type 2 diabetes mellitus treated in our hospital from March 2013 to March 2016 were analyzed retrospectively. The patients were divided into three groups including the 34 cases ( 34 eyes ) with simple excision of pterygium ( resection group ) , pterygium excision combined with conjunctival flap transplantation in 34 cases (34 eyes, as conjunctival flap group ) and pterygium excision combined with limbal stem cell transplantation in 34 cases ( 34 eyes, as stem cell group ) . The wound repair time, complications, recurrence rate, uncorrected visual acuity (UCVA), tear film break-up time ( BUT ) and basal tear secretion test (SⅠt) were observed before, and 6 and 12mo after surgery in the three groups, respectively. ·RESULTS:The postoperative UCVA of the three groups was significantly higher than that preoperation ( P =0. 039, 0. 013, 0. 024 ), and there was no significant difference among the three groups ( P = 0. 317 ). The wound repair time was 5. 67 ± 1. 45d in the resection group, which was significantly higher than that in the conjunctival flap group (4. 18 ± 0. 76d) and the stem cell group (4. 09±0. 79 d) (P<0. 001), there was no significant difference between the conjunctival flap group and the stem cell group ( P = 0. 937 ). There were 4 cases in resection group reappeared, and the recurrence rate was 11. 8%, which was significantly higher than the other two groups ( P = 0. 037 ). There were 1 recurrences in the conjunctival flap group, and the recurrence rate was 2. 9%, while the patients in the stem cell group had no obvious recurrence. SⅠt and BUT increased significantly after operation (P<0. 05), especially in conjunctival flap group and stem cell group (P<0. 001). There was no significant difference between the conjunctival flap group and the stem cell group (P=0. 845, 0. 894). · CONCLUSION: Pterygium excision combined with conjunctival flap transplantation or limbal stem cell transplantation for the treatment of type 2 diabetic patients with normal blood glucose and tear film function has the similar effect, and is better than simple pterygium excision.
