Objective:
To investigate the learning cognition and demand of medical college undergraduates for statistics course and its teaching effect, so as to better carry out the teaching work of statistics course and provide better teaching experience.
Methods:
A total of 319 undergraduates from 11 medical universities and colleges who had finished statistics course were involved to conduct a questionnaire survey by using the online questionnaire survey method.
Results:
The senior undergraduates (grade 3, grade 4, grade 5) participated in statistic course accounted for a large proportion of 94.60%; 61.90% subjects thought the course was difficult. For undergraduate public health majors and non-public health majors, more than 90% considered that it was necessary to set up the corresponding statistics courses; about 4.00% did not like the corresponding statistics courses; 75.87%, 69.52% and 50.16% thought that "teaching method", "teaching content" and "class schedule" were the main reason influencing the statistics course, respectively; and 61.9% thought that case teaching was the best way to master the course. The results also showed that all subjects had a common comprehending of statistical theory and a poor comprehending of software operation skills. About 90% of the research subjects had requirement for theoretical knowledge or software operation.
Conclusion
Colleges and universities should make theoretical courses more targeted, increase the proportion of case teaching, strengthen the teaching of software operation skills and appropriately set up corresponding training courses, to solve the problem that it is difficult to achieve satisfactory teaching effect.

ObjectiveTo investigate the trends in diabetes mortality and potential years of life lost (PYLL) among residents of Huangpu District, Shanghai from 1993 to 2021, to analyze the long-term trends of diabetic patients with different characteristics and to provide a reference for scientific prevention and control of diabetes in aging urban areas. MethodsDiabetes mortality data were obtained from the Huangpu District cause of death registration records in the Shanghai death cause registration system. Indicators such as crude mortality rate, standardized mortality rate, potential years of life lost (PYLL), average years of life lost (AYLL), annual percentage change (APC), and average annual percentage change (AAPC) were used to analyze diabetes-related mortality and life loss. Statistical analyses were performed using software SPSS 21.0 and Joinpoint 5.0.2. ResultsFrom 1993 to 2021, the average annual crude mortality rate of diabetes in Huangpu District was 46.56/100 000, and the average annual standardized mortality rate was 20.44/100 000. The crude mortality rate and standardized mortality rate of diabetes for female residents were higher than those for males. The crude mortality rate showed an overall increasing trend [AAPC=2.81% (95%CI: 0.20%‒5.49%), P<0.05], while the increase in standardized mortality rate significantly slowed [AAPC=0.15% (95%CI: -2.27%‒2.63%)], P<0.05]. The mortality rate rose rapidly in the 70‒74 years age group and peaked in the 85‒ years age group (607.69/100 000). Diabetes accounted for a cumulative PYLL of22 741 person-years, with an average annual AYLL of 1.88 years and an average annual potential years of life lost rate (PYLLR) of 0.82‰. Male residents had higher PYLL, AYLL, and PYLLR than females. ConclusionDiabetes mortality rates in Huangpu District have increased year by year, resulting in significant life loss. However, the age-standardized mortality rate increase has markedly slowed. Efforts should focus on elderly diabetic patients aged ≥70 years, by leveraging platforms such as community-based chronic disease health support centers, efforts should be made to enhance diabetes screening service for middle-aged and elderly residents. Consequently, elderly diabetic patients’ awareness of diabetes and responce to related complications is improved, which would be conducive to controling the progression of complications and reducing the mortolity risk of diabetes.

OBJECTIVE:
To explore two transcript variants expression of long noncoding RNA C6orf176 in non-small cell lung cancer (NSCLC) and the clinical pathological significance.
METHODS:
The expressions of transcript variant 1 (TV1) and transcript variant 2 (TV2) of long noncoding RNA C6orf176 in 57 NSCLC and adjacent cancerous tissues were examined by qPCR with β-actin as internal control.
RESULTS:
Based on the results of qPCR, for C6orf176-TV1, 42 cases were down-regulated and 15 cases were up-regulated. The C6orf176-TV1 level was correlated to the grade of differentiation (P<0.05) but it was not correlated with gender, age, smoking history, tumor type and TNM stage. The expression of C6orf176-TV1 had a potential value in diagnosis of NSCLC by receiver operator characteristic (ROC) curve. Area under curve (AUC) of ROC curve was 0.708 (95% CI 0.615 to 0. 802). The sensitivity and specificity were 51% and 88%, respectively. For C6orf176-TV2, 39 cases were down-regulated and 18 cases were up-regulated. The C6orf176-TV2 level was correlated with the grade of differentiation (P<0.05) but it was not correlated with gender, age, tumor size, smoking history and TNM stage. C6orf176-TV2 level had value in diagnosis of NSCLC by ROC curve. AUC of ROC curve was 0.64 (95% CI 0.531 to 0.749). The sensitivity and specificity were 49% and 75%, respectively. Of the 57 specimens, 53 cases were simultaneous up or down-regulation of C6orf176-TV1 and C6orf176-TV2. The correlation coefficient was 0.99.
CONCLUSION
The expression of C6orf176-TV1 or C6orf176-TV2 is down-regulated in NSCLC and it is correlated with the grade of differentiation. It may act as a diagnosis indicator for NSCLC patients.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.
