Objective:To investigate the current situation of junior medical students'cognition on the relationship between doctors and patients,and to provide reference for medical students'medical education and medical education reform,Methods:Self-made questionnaire was adopted to investigate the cognitive status of doctor-patient relationship among junior medical students from three medical universities in Guangzhou.Results:Totally 41.04％ of junior medical students had a basic understanding of doctor-patient relationship,and the degree of understanding of doctor-patient relationship is not different between junior and senior medical students (P ＞ 0.05);76.62％ of medical students got acquainted with the status of doctor-patient relationship mainly through the media;86.57％ of junior medical students thought that the doctor-patient relationship was tense.The cognition of doctor-patient relationship between male and female students was similar (P ＞ 0.05),and so wasit between freshmen and sophomores (P ＞ 0.05).Male and female students had the same opinion on the future trend of doctor-patient relationship (P ＞ 0.05).Many junior medical students were optimistic about the future doctor-patient relationship.Compared with freshmen,sophomore medical students were less optimistic about the future doctor-patient relationship (P ＜ 0.05).Medical students mostly agreed on the causes of medical disputes (P ＞ 0.05),believing that the main reason was the medical system.Conclusions:The cognition of the doctor-patient relationship profoundly affects the junior medical students as well as their choices of future employment and communication styles between patients and them,which may have important significance for avoiding medical disputes.Society,schools and the media should actively create a good atmosphere for the doctor-patient relationship.

Objective: To observe the efficacy of mild moxibustion combined with arthroscopic meniscal repair in the treatment of meniscal injury and to explore its action mechanism. Methods: Ninety-eight patients with meniscal injury were divided into a surgery group and a moxibustion plus surgery group by the random number table method, with 49 cases in each group. Both groups received arthroscopic meniscal repair, and the moxibustion plus surgery group was treated with add-on mild moxibustion. The Lysholm score, visual analog scale (VAS) score, and mobility of the affected knee were measured before and after treatment, and transforming growth factor (TGF)-β1 and platelet-derived growth factor (PDGF) levels were measured in the fluid of the affected knee joint. The healing of the meniscus was recorded at a follow-up visit 3 months after the surgery. Results: After treatment, the Lysholm score increased, the VAS score decreased in both groups, and the intra-group differences in both groups were statistically significant (P<0.05). The Lysholm score was higher in the moxibustion plus surgery group than in the surgery group, and the VAS score was lower in the moxibustion plus surgery group than in the surgery group. The differences between groups in both scores were statistically significant (P<0.05). The mobility of the affected knee joint increased in both groups (P<0.05), and it was greater in the moxibustion plus surgery group than in the surgery group (P<0.05). When compared with pretreatment, the levels of TGF-β1 and PDGF in the fluid of the knee joint increased in both groups (P<0.05), and the levels of TGF-β1 and PDGF in the fluid of the affected knee joint were higher in the moxibustion plus surgery group than in the surgery group (P<0.05). The healing of the meniscus in the moxibustion plus surgery group was significantly better than that in the surgery group at the follow-up visit 3 months after the surgery (P<0.05). Conclusion: The effect of mild moxibustion combined with arthroscopic meniscal repair is better than the surgery alone in improving knee function, relieving pain, increasing mobility of the affected knee, and promoting meniscal healing, which may be related to the up-regulation of TGF-β1 and PDGF levels in the fluid of knee joint.

OBJECTIVE:To analyze intervention effect of Drug Rational Usage Guidelines System(DRUGS)on antibacterial agents use in department of obstetrics and gynecology in our hospital. METHODS:The application of antibacterial agents in depart-ment of obstetrics and gynecology in our hospital during Jan.-May(before intervention)and Jun.-Nov. 2012(after intervention)were extracted in respects of drug name,preoperative medication duration,perioperative additional condition,postoperative drug with-drawal time,drug combination,usage and dosage,average hospitalization stay,hospitalization cost. The intervention effects were analyzed. RESULTS:After intervention,the type of antibacterial agents were more in line with national regulations;the proportion of type Ⅰ incision surgery without antibacterial agents increased from 57.8% to 75.2%;the prophylactic application of antibacteri-al agents in type Ⅱ incision surgery within 0.5-2 h increased from 80.2% to 97.0%. The rate of reasonable antibacterial selection, drug combination,usage and dosage increased from 76.9%,64.9%,71.3% to 89.3%,84.6%,90.2%,respectively. The average hospitalization stay and antibacterial cost per capita decreased significantly. There was statistical significance among above indica-tors before and after intervention(P<0.05 or P<0.01). CONCLUSIONS:DRUGS effectively change irrational use of antibacterial agents in department of obstetrics and gynecology,which provide a new method for the management of antibacterial agents.

Objective To explore the correlation of pretreatment EBV DNA load, EBV EA-IgA and VCA-IgA antibodies levels with the clinical characteristics, curative effect and prognosis of the patients with early-stage extranodal nasal-type NK/T-cell lymphoma (ENKTCL). Methods We analyzed the clinical features and prognostic factors of 78 ENKTCL patients. Results Positive rates of pretreatment EBV DNA, VCA-IgA and EA-IgA were 43.6%, 20.5% and 14.1%, respectively. EBV DNA was significantly associated with Ann Arbor stage, primary site, PTI and non-CR (all P < 0.05). VCA-IgA and EA-IgA were related to positive EBV DNA and non-CR (all P < 0.05). Multivariate analysis showed that age, EBV DNA and non-CR were independent prognostic factors for OS (all P < 0.05); age, EBV DNA, primary site and non-CR were independent prognostic factors for PFS (all P < 0.05). Conclusion The pretreatment positive EBV DNA is related to advanced Ann Arbor stage, PTI, primary extra-nasal subtypes of upper aerodigestive tract and poor response to treatment. The elevated levels of EA-IgA and VCA-IgA are related to positive EBV DNA and poor response to treatment. Pretreatment EBV DNA could be used for risk stratification and prognosis prediction of ENKTCL, while EA-IgA and VCA-IgA play limited role in guiding the prognosis of ENKTCL.

Objective:To construct a Soochow University model of comfortable medical procedures during peri-anesthesia period for patients undergoing radical resection of lung cancer through thoracoscope.Methods:In this prospective study, eight hundreds and sixty patients undergoing radical resection of lung cancer through thoracoscope were enrolled in our hospital in 2018.During peri-anesthesia period, the 860 patients were randomly(by the random number table method)divided into the control group(the group C receiving routine medical procedures, n=430)and the comfort group(the group S receiving the comfortable medical procedures of Soochow University model, n=430). The scores of Visual Analogue Scale(VAS), Richmond Agitation-Sedation Scale(RASS), and Thirsty Analogue Scale(TAS)were recorded at 5 min after extubation(T1), at out of the post-anesthesia care unit(T2), at 1 h(T3), 6 h(T4), 12 h(T5), 24 h(T6), 2 d(T7)and 3 d after surgery(T8)in two groups.The incidences of postoperative sore throat(POST), nausea and vomiting(PONV), catheter-related bladder discomfort(CRBD), thirst and hypothermia were recorded at T2, T6 and T8, respectively.Meanwhile, the peri-anesthesia comfort questionnaire(PCQ)and peri-anesthesia satisfaction questionnaire(PSO)were completed at T6 and T8.Results:The incidences of POST(48.6% vs.16.2%), PONV(24.9% vs.13.0%), CRBD(78.8% vs.20.9%)and thirst(74.9% vs.20.0%)were higher in the group C than in the group S at T2( P<0.05). The comfort score and satisfaction score were lower in the group C than in the group S at T6(3.14±1.04 vs.4.92±1.42, 2.67±0.89 vs.3.30±1.01)and at T8(3.84±1.83 vs.5.05±1.77, 2.74±0.84 vs.3.26±1.06)( P<0.05). Conclusions:The Soochow University model of comfortable medical procedures during peri-anesthesia period for patients undergoing radical resection of lung cancer through thoracoscope has been successfully constructed, and this model can reduce the incidence of complications, and improve the comfort and satisfaction during peri-anesthesia period.
