Objective

This study aimed to systematically construct a transitional curriculum for newly recruited surgical residents and to evaluate its preliminary application outcomes through pre and postimplementation assessments, so as to provide practical references for the design and dissemination of such curricula.

Methods

A singlecenter historical controlled design was adopted. Residents admitted in 2020 served as the traditional teaching group (preimplementation), while those admitted in 2024 served as the teaching reform group (postimplementation). Both groups completed selfadministered surveys three months after admission. Following Kern's sixstep approach, the transitional curriculum for surgical residents was developed based on needs assessment results, comprising 18 theoretical lectures and 3 practical skill training sessions, all delivered within the first three months after admission. Selfadministered questionnaires were used to assess clinical readiness and teaching satisfaction in both groups at three months postadmission. Betweengroup comparisons were performed using independent samples ttests, with Cohen's d effect sizes calculated, along with sensitivity analyses and power analyses.

Results

The teaching reform group (n=33) demonstrated higher scores across all dimensions of clinical readiness and teaching satisfaction compared with the traditional teaching group (n= 22), although none of the differences reached statistical significance(all P > 0.05). Overall clinical readiness improved from 6.82±2.13 to 7.15±1.37 (mean difference 0.33, 95% CI: -0.61 to 1.28); satisfaction with teaching work increased from 7.45±1.71 to 7.88±1.65 (mean difference 0.43, 95% CI: -0.50 to 1.35); and satisfaction with faculty instruction rose from 7.95±1.76 to 8.61±1.52 (mean difference 0.66, 95% CI: -0.24 to 1.55). Power analysis indicated that the current sample size could detect a minimum betweengroup difference of approximately 1.32 points in teaching satisfaction, whereas the observed difference (0.43) was below this threshold.

Conclusions

The transitional curriculum developed in this study provides a systematized framework of theoretical instruction and foundational skills training for newly admitted surgical residents, and its feasibility has been preliminarily validated. Its effectiveness, however, warrants further confirmation through largersample, prospective studies with objective outcome measures.

Objective To study the estimated value of general pituitary hormone levels and "overall levels of pituitary hormone" in patients with pituitary adenoma.Methods Sixty-six patients presented with non-function pituitary adenomas,admitted to our hospital from January 2009 and April 2013,were chosen in our study.Pre-and post-operative hormonal levels and MR imaging data were collected.Patients were divided into two groups:macroadenoma (1 cm＜diameter＜3 cm) group and huge adenoma (diameter＞3 cm) group,and the patients were divided into subtotal resection group (resection rate＞60％) and partial resection group (resection rate＜60％).Self-made scale of "overall levels of pituitary hormone" was performed to assess the remnant pituitary function.The levels for 6 kinds of pituitary hormones and "overall levels of pituitary hormone" were compared between each two groups.Results (1) The levels of 6 kinds of pituitary hormones between the macroadenoma group (n=38) and huge adenoma group (n=28) showed no significant difference before surgery (P＞0.05);the per-operative "overall levels of pituitary hormone" were statistically different between the macroadenoma group (19.59±2.71) and huge adenoma group (18.07±2.00,P＜0.055);there were 13 patients (34.2％) from macroadenoma group and 17 (60.7％) from huge adenoma group having one or more kinds of pituitary hormones lower than normal levels,with significant difference (P＜0.05).(2) The levels of 6 kinds of pituitary hormones between subtotal resection group (n=57) and partial resection group (n=9) showed no significant difference after surgery (P＞0.05);the post-operative "overall levels of pituitary hormone" in the subtotal resection group were significantly higher than those in the partial resection group (P＜0.05);there were 34 patients (59.6％) from subtotal resection group and 2 (22.2％) from partial resection group having one or more kinds of pituitary hormones lower than normal levels,without significant difference (P＜0.05).Conclusions The "overall levels of pituitary hormone",in which 6 kinds of pituitary hormones are seen as a whole,can assess the remnant pituitary function in pituitary adenoma patients more accurately than evaluation of the 6 kinds of pituitary hormone levels separately.
