Global health education is a field of education that focuses on health issues directly or indirectly caused by transnational factors. At present, rapid progress has been made in global health education, and universities in foreign countries are establishing educational institutions and providing various forms of education, including degree programs, and non-degree programs. Furthermore, many measures have been taken to support the development of global health education, such as financial supports and credit recognition. Learning from the international experience, China should support and promote the development of global health education during the reform of medical education, strengthen the construction of global health education institutions at universities, encourage various forms of educational activities, and enhance the internationalization of global health education.

Objective:To provide evidences on optimizing enrollment work of medical universities through identifying main factors that students considered when choosing medical universities.Methods:A Web-based questionnaire survey of 2 526 newly admitted health professions students were conducted by general survey. The questionnaire was self-designed according to literature and enrollment work practices, mainly including the basic information of students, the main influencing factors for choosing universities and majors, and the needs of enrollment promotion. Descriptive analysis, and Chi-square tests or Fisher's exact tests were conducted to analyze the data using Stata SE 14.0.Results:A total of 2 384 students participated in the survey, leading to a response rate of 94.38% (2 384/2 526). When selecting universities to study, the first five ranked factors were comprehensive strength of university, graduates' employability and university employment support, strength of distinctive disciplines, university culture, and opportunities for scientific research training. Participants who chose "very important" or "important" for these factors accounted for 94.25% (2 247/2 384), 90.52% (2 158/2 384), 89.77% (2 140/2 384), 89.26% (2 128/2 384), and 88.21% (2 103/2 384), respectively. Meanwhile, different types of participants attached different importance to these factors.Conclusions:Although enrollment strategies play an important role in enrollment competition, their effectiveness root in comprehensive university strength. The collaboration between universities and high schools should be enhanced in order to provide lectures and guidance on high school students' cognition of medical career in advance. The focus of enrollment advertising should match information appeals of different types of students. Furthermore, methods that meet the characteristics of high school students should be utilized to substantively promote the effect of enrollment advertising.

The number of dental schools increased from 55 in 2000 to 66 in 2019 in the United States. The number of public, private, and private-state-related dental schools were 40, 22 and 4, respectively. A majority of them were located in most developed areas, such as western, eastern, and southern regions of the country. In the same period, the number of freshman enrollees rose from 4 234 to 6 231 while the average of enrollees kept under 100. On the basis of learning relevant experiences of the United States, it might be necessary for China to expand the overall scale of stomatology education in order to address the shortage of dentists, take measures to increase the number of stomatology schools and improve their distribution, and control the number of enrollees per school to enhance the quality of education.

Objective:To compare the efficacy and safety between WangShiBaoChiWan and mosapride in the treatment of functional dyspepsia (FD).Methods:From September 2019 to September 2020, patients with postprandial fullness and early satiation who met the Rome Ⅳ criteria for FD diagnosis were enrolled from 15 hospitals, including the First Affiliated Hospital of Naval Medical University (Shanghai Changhai Hospital), Beijing Traditional Chinese Medicine Hospital Affiliated to Capital Medical College. The subjects were randomly divided into WangShiBaoChiWan (experimental) group and mosapride (control) group in the ratio of 1∶1. The treatment regimens were WangShiBaoChiWan+ mosapride simulator, WangShiBaoChiWan simulator+ mosapride, respectively with a treatment period of 2 weeks. The primary efficacy outcome was the improvement rates of main symptoms before and after treatment, the secondary efficacy primary efficacy outcome was the total clinical effective rate and the change of the single symptom score. And the safety indicator included adverse events. Independent sample t-test, paired t-test and chi-square test were used for statistical analysis. Results:A total of 251 FD patients were enrolled in the full analysis set, including 124 in the experimental group and 127 in the control group; 241 FD patients were in the per-protocol analysis set, including 117 in the experimental group and 124 in the control group. The analysis of per-protocol analysis set showed that the improvement rates of the main symptoms of the experimental group and the control group were (66±29)% and (60±30)%, respectively, and the difference was not statistically significant ( P>0.05). The improvement rate of the main symptoms of the experimental group reached 117% of that of the control group, which exceeded the expected non-inferiority standard of 80%. The total clinical effective rates of the experimental group and the control group were 76.07% (89/117) and 75.81% (94/124), respectively, and the difference was not statistically significant ( P>0.05). The results of full analysis set showed that the incidence of adverse events of the experimental group and the control group was 1.62% (2/124) and 1.57% (2/127), respectively, and the difference was not statistically significant ( P>0.05). There were no serious adverse events in the two groups. Conclusion:The improvement rate of the main symptoms of WangShiBaoChiWan is not inferior to that of mosapride in the treatment of FD, and it has good safety.

Objective:To analyze employment status and its tendency of eight-year program clinical medical graduates and explore its implications to talent cultivation using employment data from a university in Beijing.Methods:Descriptive analysis was used in this study. Indicators that were analyzed included quantity of employment, employment rate, employment region and specialty.Results:Between 2009 and 2021, a total of 2 281 eight-year clinical medical students graduated in the university. Among them, 2 188 (96.0%) of them were employed in the year of graduation. On average, 90.8% (2 034/2 241) of them were employed by medical institutions although the percentage decreased over years. A majority of them chose to work in economically developed provinces of eastern China. Those chose to work in Beijing accounted for 78.7% (1 723/2 188), the highest percentage among all provinces. The top two specialties of choice were surgery and internal medicine, which respectively accounted for 33.0% (753/2 281) and 24.4% (557/2 281). Only a few of them chose to study some specialties that were challenged by a serious shortage of physicians, including pediatrics, mental diseases and mental health.Conclusion:Although the employment status of eight-year clinical medical graduates are good, it is still necessary to pay attention to the new tendency of employment, and further improve training scheme. Meanwhile, more guidance on choice of secondary specialties are needed to build a competent talent team for specialty development. Finally, education of curriculum iedology and politics should be strengthened to encourage them to work in specialties and remote provinces that face a serious shortage of physicians.

【Objective】 To analyze the correlation between the expressions of CD10,CA9 and CD133 and the prognosis of patients with metastatic renal clear cell carcinoma (mccRCC) treated with sorafenib or sunitinib. 【Methods】 A total of 80 mccRCC patients who received sorafenib or sunitinib as first-line therapy were retrospectively enrolled. Immunohistochemical staining (IHC) was performed for CD10,CA9 and CD133 in tumor tissue samples to analyze the correlation between the expression of each marker and clinicopathologic variables. Univariate and multivariate Cox proportional risk models were used to analyze prognostic factors of progression free survival (PFS) and overall survival (OS),and Kaplan-Meier survival analysis was performed for CA9 expression and PFS,OS in the treatment subgroups. 【Results】 Altogether 37 patients (46.25%) had PFS,and the median PFS (mPFS) was 24.9 months (95%CI:16.5-33.2 months),while 55 patients (68.75%) died and the median OS (mOS) was 44.2 months (95%CI:14.6-73.7). Low expression of CD10 was correlated with high Fuhrman grade (χ²=6.241,P=0.012),lymph node metastasis (χ²=5.952,P=0.015),and the number of metastatic organs ≥2 (χ²=8.205,P=0.004). Univariate analysis showed that Fuhrman grade,number of metastatic organs and lymph node metastasis were the prognostic factors of PFS (P<0.05),while the number of metastatic organs,lymph node metastasis and CA9 expression were the prognostic factors of OS (P<0.05). Multivariate analysis showed that Fuhrman grade was an independent factor of PFS (HR=2.457,95%CI:1.126-5.365,P=0.024),and the number of metastatic organs was an independent prognostic factor of OS (HR=1.857,95%CI:1.048-3.290,P=0.034). Survival analysis in subgroups showed that high CA9 expression in the sorafenib group was associated with longer OS (HR=0.401,95%CI:0.204-0.787,P=0.008). 【Conclusion】 Low expression of CA9 is an non-independent risk factor for OS,while CD10 and CD133 cannot be used as prognostic factors for mccRCC patients. Since mccRCC patients with low CA9 expression have less survival benefit from sorafenib and sunitinib,they can choose target therapy combined with immunotherapy or dual immunotherapy according to the guidelines to improve prognosis.

Objective:To explore the safety and feasibility of optimized pathological evaluation system of donor's kidney and modified surgery during adult dual kidney transplantation(DKT)and evaluate its effectiveness to provide more alternative protocols for kidney transplantation from extended criteria donors.Methods:DKT was performed in 10 recipients using the same protocol from June 2019 to May 2021.And retrospective reviewing was performed for clinical data, including characteristics of donors and recipients, optimized pathological evaluation system, modified surgery, treatment regimens, complications and follow-ups.Results:There were 8 male and 2 female donors with an age of(57.9±12.8)years and BMI(24.1±4.1)kg/m 2.The percentage of DCD was 70% and DBD 30%.The serum creatinine before procurement was 107.6(93.3-163.5)μmol/l.Zero-point puncture biopsy was performed for both kidneys and optimized pathological evaluation system was implemented(Banff criteria & Remuzzi score). The pathological results indicated that glomerular sclerosis for left and right kidneys were 2.0(1.5-2.0)and 1.5(1.0-2.0). And Remuzzi score for left and right kidneys were(4.4±1.2)and(3.6±1.5)points respectively.All recipients were male with an age of(43.1±9.0)years and BMI(22.2±1.9)kg/m 2.All PRAs were negative pre-operation.Modified surgery was performed in all recipients(two kidneys were implanted outside iliac vessels without patch and artery of superior kidney was anastomosed to internal iliac artery). Operative duration was(195±54.3)min and serum creatinine before discharge 125.0(102.0-199.0)μmol/L.Renal dynamic scintigraphy indicated that glomerular filtration rate was(30.0±8.2)ml/min for left kidney and(29.2±13.9)ml/min for right kidney.MRA results indicated that morphologies of renal arteries and veins were regular.The time between operation and discharge was(22.4±4.7)days.Compared with SKT, serum creatinine before discharge of DKT was lower and DGF incidence of DKT was higher without statistical significance.The time between operation and discharge was longer for DKT than that for SKT( P<0.05). The complications consisted of 20% donor derived infection(DDI)and 50% DGF.And there was no surgical complication associated with vessels and ureter.Renal function remained stable during 6-month follow-ups. Conclusions:Optimized pathological evaluation system of donor's kidney and modified surgery during adult dual kidney transplantation are both safe and feasible.The postoperative function of transplanted dual kidney is successfully restored.However, long-term follow-ups are required for evaluating its effectiveness.

Objective:To construct an effective survival nomogram for patients with clear cell renal cell carcinoma (ccRCC) using a large sample sized Chinese dataset, which can be used to predict individual 3- and 5-year overall survival (OS) precisely.Methods:The data of 672 ccRCC patients received operation diagnosed at Xijing Hospital from January 2012 to December 2016 were retrospectively analyzed. There were 467 males and 205 females. Their median age was 56 years old (ranging 23-83 years old). There were 327 patients with tumor on the left kidney and 345 patients with tumor on the right kidney. Clinical stageⅠ, Ⅱ, Ⅲ, Ⅳ were 584, 47, 19 and 22 cases, respectively. At the time of diagnosis, 504 patients were asymptomatic and 168 patients were symptomatic. Preoperative alkaline phosphatase was 80 (41-240) U/L. Preoperative serum albumin was 44.8 (30.5-59.8) g/L. Preoperative neutrophil absolute value/lymphocyte absolute value (NLR) was 2.25 (0.81-9.89). Preoperative platelet count was 205 (82-589)×10 9/L. Preoperative creatinine was 97 (55-230) μmol/L. Radical nephrectomy was performed in 420 (62.5%) patients and partial nephrectomy was performed in 252 patients. Cox multivariate analysis was used to determine the independent predictors of the postoperative OS. Then, the nomogram was constructed using R software, which integrates all independent predictors according to the coefficients in the multivariate analysis. Moreover, the performance of the nomogram was evaluated using the consistency index (C-index) and the calibration plots. Results:Cox multivariate analysis results showed that age at diagnosis ( P<0.001), clinical TNM stage ( P<0.001), preoperative NLR ( P=0.012), preoperative alkaline phosphatase ( P=0.002) and preoperative albumin ( P<0.001) were the independent predictors of postoperative OS in ccRCC patients. The nomogram established by integrating these five factors had a good discriminatory ability (C-index=0.819, 95% CI 0.813-0.825), and the calibration plots showed that excellent agreements between the nomogram prediction and the actual observation were achieved. Conclusions:Based on a large sample sized Chinese dataset, this study established an effective survival model for patients with ccRCC and good performance of the nomogram was demonstrated by internal validation. Our nomogram can help urologists to predict individual 3- and 5-year OS accurately for Chinese ccRCC patients.

Objective: To investigate the pathological characteristics of bladder low malignant potential papillary urothelial tumors (PUNLMP) and the predic factors of recurrence and pathological progress. Methods: We retrospectively analyzed 150 patients of bladder PUNLMP in the Department of Urology of Xijing Hospital from February 2009 to February 2019. Among the 150 patients, 118 patients were males and 32 patients were females. The average age was 57 years, ranging 20-93 years. There were 112 cases of single tumor and 38 cases of multiple tumor. All patients received transurethral resection of bladder tumor (TURBT) and 136 patients received bladder infusion chemotherapy, including 61 patients for pirarubicin, 58 patients for gemcitabine, 11 patients for epirubicin, and 11 patients for mitomycin. 14 patients did not receive bladder infusion chemotherapy. In this study, univariate and multivariate logistic regression analysis were used to investigate independent predictors of recurrence and pathological progression in patients of bladder PUNLMP who received TURBT. Results: The average follow-up time was 25.6 months, ranging 5.5-122.7 months. Among the patients, 21 patients occurred recurrence. The recurrent duration ranged from 2.2 to 108.3 months (mean 23.1 months). 12 patients had pathological progression, including 9 patients for low-grade non-invasive papillary urothelial carcinoma, 1 patient for high-grade non-invasive papillary urothelial carcinoma, 1 patient for high-grade invasive urothelial carcinoma, 1 patient for squamous cell carcinoma. The progressive duration ranged from 2.2 to 56.3 months (mean 21.5 months). Among the 150 patients, 18 patients with inverted growth pattern did not recur. There were significant differences in the number of tumors and the tumor length between the recurrence and non-recurrence groups, same as the progression and non-progression groups. The univariate and multivariate logistic regression analysis results showed that the number of tumors was an independent predictor of tumor recurrence (OR=7.884, 95%CI 2.815-22.082, P<0.05)and progression(OR=6.107, 95%CI 1.659-22.473, P=0.006) in patients of bladder PUNLMP. Bladder infusion chemotherapy failed to reduce the risk of recurrence and progression. Conclusions About 14% (21/150) patients of bladder PUNLMP reoccurred after TURBT. About half of them had pathological progression, and most of them progressed to low-grade non-invasive papillary urothelial carcinoma. Multiple tumors was an independent risk factor for postoperative recurrence and progression. Bladder infusion chemotherapy did not reduce the risk of recurrence and progression in patients of bladder PUNLMP.

Curriculum for undergraduate medical education in the United Kingdom consists of two parts, namely pre-clinical and clinical courses. Medical undergraduate students are encouraged to study for a second degree and individualized education is emphasized. Various methods are employed in teaching highly integrated courses, mainly according to human organs and systems or physiological functions. Drawing lessons from relevant experiences of the United Kingdom, China should further strengthen the formulation and supervision of standards and guidelines for undergraduate medical education, and actively promote the reform of teaching models in order to facilitate the connection and integration between basic medical education and clinical practice. It's also suggested that priorities be given to the cultivation of compound medical talents and individualized education for medical students. Finally, educational system should be further improved in order to enhance the effects of clinical practice.
