ObjectiveTo evaluate the reliability and validity of Chinese version of Asia-Pacific functional gastrointestinal disorders (FGIDs) questionnaire. Methods The standardized scale translation program was used to translate the Asia-Pacific functional gastrointestinal disorders questionnaire into Chinese version.From April to May 2011,the functional gastrointestinal disorders (FGID) out-patients of the Department of Gastroenterology at the First Affiliated Hospital of Sun Yat-Sen University were asked to complete the Chinese version of the questionnaire,then the feasibility,reliability and validity of the questionnaire were evaluated.ResultsA total of 58 FGIDs patients finished the questionnaire,of which 37 patients with good compliance finished the 2-week interval questionnaire.The retest reliability of the first part of the questionnaire was good (including basic information,disease duration and alarm symptoms),all the test-retest coefficients were more than 0.70.The percentage of poor,medium and good retest reliability items of the second part of the questionnaire (including the symptoms of gastrointestinal system) was 27.8％,61.1％ and 11.1％respectively.After the data was transformed into binary data according to Rome Ⅲ diagnostic criteria,the percentage of poor,medium and good retest reliability items was 5.5％,41.7％ and 52.8％respectively.The percentage of poor,medium and good retest reliability items of the third part of the questionnaire (including previous medical treatment,medication and the impact of the disease on life,etc) was 36.0％,40.0％ and 24.0％ respectively.The validity of the questionnaire was moderate according to the Rome Ⅲ diagnostic criteria.Conclusion The Chinese version of Asia-Pacific functional gastrointestinal disorders is feasible and can be used to screen the adult FGIDs under the Chinese cultural background.

Humanistic doctor-patient communication is an essential capability for medical workers and is as impor -tant as medical technology .Its education has been getting more and more attention in recent years .However , the training and evaluation of humanistic doctor-patient communication as a practical other than theoretical capability has been difficult .A new method , clinical scenery drama , based on psychodrama and role theory , is developed by Dept.of Psychological Medicine , Peking Union Medical College Hospital from recent 10 years of medical doctor and student training .In clinical scenery drama , medical students are thrown to different roles to empathize with their feelings and conflicts , try to resolve clinical dilemma with humanistic communication technique besides medi-cal technology .Then the sharing and comments from teachers and observers help students to understand the situa -tion from other perspectives and think about other possible solutions .

Interleukin 24 ( IL-24) has a good prospect in tumor therapy because it can specifically inhibit proliferation in a variety of tumor cells in vitro and in vivo and induce apoptosis of tumor cells without affecting normal cells .Gene therapies which use recombinant adenovirus as a vector have some limitations that restrict the clinical application of IL-24. In comparison, protein drugs have tremendous advantages .In this paper, the progress in research on IL-24 gene engineering protein is elaborated .

Gastrointestinal stromal tumors(GIST) are the most common mesenchymal tumors of the gastrointestinal tract. Most of these stromal tumors are characterized by mutations in the KTT or platelet-derived growth factor receptor α (PDGFRA) genes, resulting in the constitutive activation of tyrosine kinase signaling. Tyrosine kinase inhibitors(TKI), such as imatinib and sunitinib, provide the standard first-line and second-line therapy for patients with metastatic or unresectable GIST. Imatinib resistance has been a challenging problem in clinical practice and raised great concern. This review introduces the underlying mechanisms of imatinib resistance and advances of treatment strategies. Reasonable individual treatment with the guidance of molecular biology is promising to improve the efficacy and the quality of life for GIST patients.

Imatinib is the key medication for adjuvant therapy in gastrointestinal stromal tumors(GIST) and the first line therapy for patients with metastatic or recurrent GIST. Preoperative treatment with imatinib may improve R0 resection rate and provide the chance of metastasectomy for cytoreduction as well as prolonging patient's survival. We investigate the significance of neoadjuvant therapy of imatinib and the timing of surgery by reviewing clinical trials and consensus in recent years.

Objective:To explore the relationships between serum lipids, CA153 level and breast cancer incidence and clinicopathological features of patients.Methods:A total of 198 patients with breast cancer diagnosed and treated at Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School were enrolled as the case group, and 198 healthy women were selected with 1∶1 age pairing as controls. Five milliliters of fasting venous blood was collected to measure serum lipids levels in all subjects and CA153 levels in breast cancer patients. The difference of serum lipids levels between the two groups was compared. Logistic regression model was used to analyze the risk factors of breast cancer. For 165 breast cancer patients who did not receive neoadjuvant chemotherapy, independent sample t-test was used to compare serum lipids and CA153 levels in breast cancer patients with different pathological features, and Pearson correlation analysis was used to calculate the correlation between variables and CA153. Results:The triglyceride (TG) levels in the case group and the control group were (1.22±0.73) mmol/L and (1.06±0.52) mmol/L respectively, and the difference was statistically significant ( t=2.559, P=0.011); the total cholesterol (TC) levels were (4.47±0.86) mmol/L and (4.99±0.80) mmol/L respectively, and the difference was statistically significant ( t=-6.228, P<0.001); the high-density lipoprotein cholesterol (HDL-C) levels were (1.32±0.34) mmol/L and (1.53±0.38) mmol/L respectively, and the difference was statistically significant ( t=-5.913, P<0.001). Higher TC and HDL-C levels were independent protective factors for breast cancer ( OR=0.350, P<0.001; OR=0.531, P=0.013). The TC levels in lymph node positive and lymph node negative patients were (4.36±0.73) mmol/L and (4.67±0.83) mmol/L respectively, and the difference was statistically significant ( t=-2.518, P=0.013); low-density lipoprotein cholesterol (LDL-C) levels were (2.53±0.58) mmol/L and (2.77±0.70) mmol/L respectively, and the difference was statistically significant ( t=-2.312, P=0.022). The TC levels in patients with stage Ⅰ and stage Ⅱ/Ⅲ were (4.90±0.89) mmol/L and (4.46±0.76) mmol/L respectively, and the difference was statistically significant ( t=2.855, P=0.005); LDL-C levels were (2.95±0.71) mmol/L and (2.60±0.63) mmol/L respectively, and the difference was statistically significant ( t=2.705, P=0.008). The level of CA153 in triple-negative breast cancer patients [(14.94±7.45) U/ml] was significantly higher than that in non-triple-negative breast cancer patients [(11.96±5.96) U/ml], and the difference was statistically significant ( t=2.359, P=0.020). The level of CA153 was positively correlated with the level of TG ( r=0.167, P=0.032). Conclusion:Dyslipidemia is associated with an increased risk of breast cancer. The levels of serum lipids vary among patients with different lymph node status and tumor stages. CA153 level is positively correlated with TG level to some extent.

Objective:To construct a primary health care institutions performance evaluation index system from the perspective of health value orientation under the background of countywide medical alliances construction.Methods:From May 2021 to February 2022, preliminary screening was made on core performance evaluation indexes via literature review; purposive sampling was used to select the dean/vice dean, persons in charge of medical service, and those in charge of public health service responsible for performance evaluation at the community health service center. Then semi-structured interviews were made on the existing performance evaluation and assessment plans as well as existing problems of primary medical and health institutions. Based on the " input-process-output" performance evaluation model, the thematic framework analysis method was used to analyze the interview data, and combined with literature research results, a preliminary performance evaluation index system for primary medical and health institutions was built under the guidance of health value. From March to May 2022, the Delphi expert consultation method was used to evaluate the importance and operability of indexes. The threshold method was used to screen indexes, and analytic hierarchy process was used to calculate the weights of evaluation indexes.Results:The health value oriented performance evaluation index system for primary healthcare institutions included 3 first-level indexes, 9 second-level indexes, and 50 third-level indexes. The first-level indexes were output (0.377 3), input (0.336 3), and process (0.286 4) in descending order of weight. The top three weighted second-level indexes were health manpower(0.177 8), health literacy and health outcomes (0.157 6), as well as responsiveness and satisfaction (0.142 6). The third-level indexes included 17 medical indexes, 16 prevention indexes, and 17 medical prevention integration indexes. The top three weighted indexes for inpatient services were resident satisfaction with medical treatment (0.052 4), medical staff satisfaction (0.050 1), and responsiveness of residents seeking medical treatment (0.040 1); The top three weighted third-level indexes excluding inpatient services were resident satisfaction with medical treatment (0.052 4), medical staff satisfaction (0.050 1), and surplus funds used for personnel incentives (0.045 5).Conclusions:The performance evaluation index system of primary health care institutions built under the health value orientation is scientific, conducive to promoting the health-orientated transformation and improving the efficiency of primary health care services.

Objective To evaluate recurrence after mandibular distraction osteogenesis in adult patients with hemifacial microsomia using the digital three dimensional measurement.Methods Nine adult hemifacial microsomia patients were evaluated using the method of digital measurements with three dimensional computed tomography.Three observation points were studied:pre-operation (T0),post-operation (T1) and follow-up (T2).The length of ramus (H for normal side and h for affected side),the length of body (L for normal side and l for affected side) and distance between pogonion and facial midline (D) were measured and the recurrence rate (R) was calculated.Results Percentages of h/H at T0,T1,T2 were (58.19±12.06)％,(87.09±17.92)％and (81.13±30.57)％,which had statistical significance respectively.2.Percentage of l/L at T0,T1,T2 were (87.70±7.86)％,(90.69± 5.77) ％ and (90.11±5.62)％,respectively,which had statistical significance between T0 and T1.3.Lengths of D at T0,T1,T2 were (13.66±3.28) mm,(4.926±1.75) mm and (6.616±1.82) mm,respectively,which had statistical significance between T0,T1 and T0,T1.4.Average R was (22.80± 9.73) ％.Conclusions Varying degrees of recurrence do happen in both ramus and body of mandibular after distraction osteogenesis.While it is demonstrated that the mandible grows obviously after operation compared to that pre-operation,Meanwhile,the facial symmetry is also improved significiantly.

Objective: To investigate the influence of mandibular distraction osteogenesis on masticatory function by analyzing the maximal bite force before and after surgery. Methods: From May 2014 to November 2015, 22 hemifacial microsomia cases, ageing from 6 to 10 years old, underwent mandibular distraction osteogenesis and their biting force data were collected. The maximal bite forces in incisor area, bilateral premolar area and molar area were measured before surgery and 1 year after surgery. Results: The average maximum bite forces in the molar area of the affected side, premolar area of the affected side, incisor area, premolar area of the unaffected side, molar area of the unaffected side were (170.6±42.8)N, (141.9±34.9)N, (89.7±18.8)N, (169.3±29.0)N and (230.2± 56.4)N respectively before surgery. Statistics indicated that most patients had uneven distribution of bite force between the affected side and unaffected side before surgery. And they changed to (198.8±44.0)N, (151.8±31.1)N, (88.9±18.0) N, (167.8±26.1)N and (234.3±52.5)N respectively 1 year after surgery, showing that the bite force in the molar area of the affected side was significantly improved by the surgery(P<0.05). Regression analysis showed that the postoperative bite force distribution had a tendency to become more symmetrical in hemifacial microsomia patients. Conclusions Mandibular distraction osteogenesis can improve the bite force of the affected side in hemifacial microsomia patients and enhance the balance of masticatory in the long-term postoperatively.

Objective The purpose of this study was to compare the self-evaluation and doctor-patient orientation between medical students and residents before the courses in different communication sections,and gave guide to different objects for their targeted teaching.Methods We set a sample made of 331 medical students and 308 residents who were trained in Clinical communication skills course in Peking Union Medical College from Oct.2009 to Oct.2013.Before the course,they were investigated by two self-assessment questionnaires.One is communication skills and occupation practice confidence;the other is doctor-patient orientation.Their result data were analyzed and handled by SPSS 17.0 software,adopting an independent samples t test.Results The order of the different aspects of doctor patient communication skills was same in two groups,gathering complete history [(4.340 ± 0.756) vs.(4.050 ± 0.707)] first,and establishing good doctor patient relationship [(4.310 ±0.740) vs.(4.030 ±0.790)],discussing a therapeutic plan with patient [(4.050 ± 0.812) vs.(3.600 ± 0.823)],informing bad news [(3.850 ± 0.897) vs.(3.260 ± 0.907)] followed.According to the self-assessment,residents were more confident than medical students in all these aspects above mentioned and establishing good doctor patient relationship.The doctorpatient orientation scale indicated that the residents group is more inclined to doctor-centric mode than the medical students group.Conclusion This study suggested that the residents is more confident in doctorpatient communication skills than medical students,while is less inclined to patient-centric mode than them.The focus of the communication teaching is similarity in the distribution of the two groups.Medical students' communication curriculum needs to take into account the limited clinical experiences,and training for residents needs to emphasize the capacity of empathy and perspective-taking.
