Objective:To explore the practical effects of achieving transformative learning in students based on the "case-based+problem-oriented" teaching method for the course of "orthopedic rehabilitation".Methods:A "case-based+problem-oriented" method was introduced in clinical courses for students in the rehabilitation therapy program at Tianjin Medical University. The students in the class were randomly divided into the "case-based+problem-oriented" teaching group (56 students) and the traditional teaching group (57 students). This study compared students' exam scores for different types of theoretical questions at the end of the semester. A self-filled anonymous questionnaire survey was conducted to evaluate the effectiveness of transformative learning, including the understanding of rehabilitation theory, learning interest, doctor-patient communication ability, disease analysis and judgment ability, and rehabilitation practice ability. SPSS 20.0 was used for t test and χ2 text. Results:The "case-based+problem-oriented" teaching group achieved significantly higher scores in various types of questions and total scores compared with the traditional teaching group [(85.67±4.78) vs. (72.98±6.49), t=8.78, P=0.004)]. Students in the "case-based+problem-oriented" teaching group showed higher interest in transformative learning and a considerably increased awareness of knowledge acquisition and innovative transformation. Students in the "case-based+problem-oriented" teaching group demonstrated higher abilities in theoretical learning, communication, disease exploration, and analytical judgment in this major and course. Conclusions:The "case-based+problem-oriented" clinical transformative teaching method integrates the theoretical teaching, clinical thinking, and medical training, promotes the students' enthusiasm for learning, and improves their proactive learning of knowledge and ability to transform and innovate.

Objective:To systematically integrate qualitative research on the real experience and management of cancer pain in adult cancer patients, so as to provide reference for improving the management of cancer pain in adult cancer patients and reducing their cancer pain.Methods:Qualitative research literature on the real experience and management of cancer pain in cancer patients was systematically searched in Cochrane Library, PubMed, Web of Science, CINAHL, Embase, ProQuest, Scopus, China Biomedical Database, China National Knowledge Infrastructure, Wanfang Data, and VIP. The search period was from database establishment to August 2023. The literature was evaluated using the quality evaluation criteria for qualitative research of the Joanna Briggs Institute Evidence-Based Health Care Center. The aggregation Meta-synthesis method was used to integrate and summarize research results.Results:A total of 16 articles were included, and 78 results were extracted to form 11 categories, which were summarized into four integrated results of the cognitive status of adult cancer patients towards cancer pain, the impact of cancer pain on patients, self-management strategies for cancer pain, and medical experiences related to cancer pain.Conclusions:Adult cancer patients face obstacles in alleviating cancer pain, such as lack of awareness of cancer pain, negative impacts, inadequate self-management strategies, and poor medical experience. Patients need to improve their self-management strategies, and the country and medical institutions should provide comprehensive support to enable patients and clinical medical and nursing staff to manage cancer pain.

Objective:To assess the diagnostic performance of 68Ga-PSMA PET/CT and mpMRI in initial staging of prostate cancer. Methods:A retrospective analysis was conducted on patients with initial diagnosis of prostate cancer who underwent prostatectomy at Fudan University Shanghai Cancer Center from December 2021 to June 2023. All had biopsy-confirmed prostate cancer preoperatively and had not undergone any anti-tumor treatment. Prior to surgery, all patients underwent 68Ga-PSMA PET/CT and mpMRI scans. The surgical samples were processed by whole-mount slides pathology. Thirty patients were included, with a median age of 68 years (range 67-76 years). The preoperative median PSA level was 17.91 ng/ml (range 9.41-39.53 ng/ml). The median interval between the two examinations was 21.00 days (range 2.75-35.50 days). Based on the postoperative whole-mount slides pathology which was the gold standard, we compared the sensitivity and specificity of 68Ga-PSMA PET/CT and mpMRI in diagnosing extraprostatic extension, seminal vesicle invasion, and intraprostatic tumor lesion. Results:According to the postoperative pathology, among the 30 patients, 12 had extraprostatic extension (EPE), 8 had seminal vesicle invasion (SVI). Among the 50 lesions found before surgery, postoperative pathology showed that 38 of them were clinically significant prostate cancer lesions (76.0%, 38/50). Using whole-mount pathology, preoperative mpMRI, and 68Ga-PSMA PET/CT imaging for triple fusion comparison, the sensitivity and specificity of 68Ga-PSMA PET/CT in diagnosing EPE were 66.7% (8/12) and 88.9% (16/18), respectively. The sensitivity and specificity of mpMRI in diagnosing EPE were 50.0% (6/12) and 83.3% (15/18), respectively. In diagnosing SVI, the sensitivity and specificity of 68Ga-PSMA PET/CT were 50.0% (4/8) and 86.3% (19/22), respectively. The sensitivity and specificity of mpMRI were 75.0% (6/8) and 90.9% (20/22), respectively. When diagnosing clinically significant tumor lesions within the prostate, the sensitivity of 68Ga-PSMA PET/CT was 89.5% (34/38), which was significantly better than the mpMRI of 63.2% (24/38), with no significant difference in specificity. Conclusions:The sensitivity of 68Ga-PSMA PET/CT in diagnosing intraprostatic lesions was significantly higher than that of mpMRI, with no significant difference in specificity.

Objective:To explore the efficient prognostic factors of cryotherapy for prostate cancer in the real-world setting.Methods:The clinical data of 105 prostate cancer patients treated at the Fudan University Shanghai Cancer center from January 2021 to December 2023 were analyzed retrospectively. The patients were divided into a non-metastatic group (62 cases, 58.7%) and a metastatic group (43 cases, 41.3%) based on the presence or absence of distant metastasis. In the non-metastatic group, the median age was 79 years (range 73 to 82), the initial PSA was 20 ng/ml (range 10 to 47), 37 cases (59.7%) received neoadjuvant endocrine therapy, and the preoperative PSA was 8 ng/ml (range 2 to 14). The ISUP grades were Grade 1 in 4 cases (6.5%), Grade 2 in 11 cases (17.7%), Grade 3 in 16 cases (25.8%), Grade 4 in 16 cases (25.8%), and Grade 5 in 15 cases (24.2%). The T-stages were T 2 in 49 cases, T 3 in 6 cases, and T 4 in 7 cases. All cases were N 0. In the metastatic group, the median age was 68 years (range 62 to 74), the initial PSA was 64 ng/ml (range 27 to 200), 42 cases (97.7%) received neoadjuvant endocrine therapy, and the preoperative PSA was 0 ng/ml (range 0 to 3). The ISUP grades were Grade 1 in 0 cases, Grade 2 in 5 cases (11.6%), Grade 3 in 3 cases (7.0%), Grade 4 in 19 cases (44.2%), and Grade 5 in 16 cases (37.2%). The T-stages were T 2 in 29 cases (67.4%), T 3 in 8 cases (18.6%), and T 4 in 6 cases (14.0%). The N-stages were N 0 in 38 cases (88.4%) and N 1 in 5 cases (11.6%). The M-stages were M 1a in 5 cases (11.6%), M 1b in 35 cases (81.4%), and M 1c in 3 cases (7.0%). The difference in T-stage between the two groups was not statistically significant ( P=0.346), while differences in other indicators were statistically significant ( P<0.05). The cryotherapy for prostate cancer was performed under general or local anesthesia, with the patients in the lithotomy position and a F20 three-lumen catheter was placed for continuous irrigation. Under transrectal ultrasound guidance, the cryoprobes were inserted parallel to the probe through the perineum, with a safe distance of 3 mm from the bladder wall. A whole-gland freezing mode was adopted, starting from the ventral side and freezing layer by layer towards the rectal side. Ultrasound was used in real-time to observe the ice ball's position and extent, adjusting it during ablation to conform to the prostate's margins while protecting surrounding structures. After ablation, the cryoprobes were removed, the puncture sites were disinfected with povidone-iodine, and gauze was applied for 20 seconds to achieve hemostasis before applying dressings. The catheter was removed 10 days postoperatively. PSA levels were rechecked on the first postoperative day and at 6 and 12 weeks postoperatively. The ratio of PSA on the first postoperative day to preoperative PSA was defined as the PSA release rate. Biochemical recurrence was defined as a PSA increase of more than 0.2 ng/ml above the postoperative nadir. The PSA progression-free survival time and the incidence of complications were compared between the two groups. Results:All procedures were successfully completed. The PSA release rates for the non-metastatic and metastatic groups were 4.2 (2.2, 6.4) and 3.9 (1.5, 6.7), respectively, with no statistical significant difference ( P=0.8272). The median PSA at 6 weeks postoperatively was 0.23 (0.01, 1.22) ng/ml, and at 12 weeks it was 0.02 (0.01, 0.49) ng/ml. The median PSA for the non-metastatic group was 0.42 (0.25, 1.00) ng/ml at 6 weeks, and it was 0.03 (0.01, 0.57) ng/ml at 12 weeks. For the metastatic group, the median PSA was 0.30 (0.14, 0.50) ng/ml at 6 weeks, and it was 0.02 (0.01, 1.17) ng/ml at 12 weeks. The median follow-up period was 339 days (range 128 to 571). No Clavien-Dindo grade ≥2 complications occurred postoperatively. One case (0.9%) experienced bladder neck stricture one month postoperatively, which improved by transurethral resection of the prostate (TURP). Two cases (1.9%) experienced urinary retention seven days postoperatively, which resolved after re-catheterization for two weeks. No urinary incontinence was reported. Two non-tumor-related deaths occurred (1.9%), one due to cardiac disease and the other due to complications from COVID-19. During follow-up, 29 cases (27.6%) experienced PSA progression, with a median PSA progression-free survival time of 808.0 days. The median PSA progression-free survival time was not reached in the non-metastatic group, while it was 764.0 days in the metastatic group. There was no statistical significant difference in PSA progression-free survival between the two groups ( P=0.422). Univariate analysis showed that preoperative PSA ( HR=1.02, 95% CI 1.00-1.03, P=0.048), T 3 stage ( HR=9.00, 95% CI 2.59-31.25, P<0.01), and T 4 stage ( HR=5.83, 95% CI 1.68-20.21, P=0.005) were prognostic factors for PSA progression-free survival. Multivariate analysis showed that T 3 stage ( HR=9.08, 95% CI 2.47-33.45, P<0.01) and T 4 stage ( HR=4.50, 95% CI 1.18-17.22, P=0.028) were independent prognostic factors for PSA progression-free survival. Conclusions:Cryotherapy for prostate cancer has a high safety profile. The efficacy of Cryotherapy is better in patients with T-stage

Objective:To analyze the levels of antibody to measles virus in cord blood of newborns in Ankang city, and provide reference for the development of measles prevention and control measures and strategies.Methods:From January to December, 2023, 1 058 pregnant women from 10 county-level general hospitals in Ankang city were recruited in this study. Neonatal umbilical cord blood samples were collected for detecting IgG antibody against measles with ELISA. SPSS 21.0 software was used to analyze the positive rate of antibody to measles virus and the influencing factors.Results:The overall positive rate of IgG antibody to measles virus was 89.22% (944/1 058), and the geometric mean concentration (GMC) was 570.26 mlU/ml. The positive rates of IgG antibody against measles virus in umbilical cord blood of neonates born to women aged ≤20, 21-25, 26-30, 31-35, and ≥36 years old were 91.07% (51/56), 90.27% (232/257), 89.54% (351/392), 88.12% (230/261), and 86.96% (80/92), respectively (χ 2=1.355, P=0.852). Multivariate logistic regression analysis showed that the positive rate of IgG antibody against measles virus in umbilical cord blood samples was higher in neonates with gestational age ≥37 weeks than in those with gestational age <37 weeks [OR (95%CI): 0.403 (0.262-0.622)]. Besides, the positive rate was also higher in newborns with a birth weight of 3.0-3.5 kg than in those with birth weight <3 kg or ≥3.5 kg [OR (95%CI): 0.868 (0.462-1.629), 1.765(1.087-2.865)]. Conclusions:The positive rate and the GMC of IgG antibody to measles virus in neonatal umbilical cord blood decrease with maternal age. It is recommended that women of childbearing age should receive supplementary immunization with measles-containing vaccine before pregnancy.

Objective:To explore the clinical effect of perforator pedicled propeller flap (PPPF) in reconstruction of soft tissue defect in ankle and foot, as well as the role of preoperative ultrasonography in assistance of the location of perforators in donor site.Methods:From January 2017 to June 2023, the Department of Microorthopedics of the Second Affiliated Hospital of Luohe Medical College of Higher Education applied PPPF to reconstruct small and medium-sized soft tissue defects in the ankle and foot for 26 patients. The patients were 17 males, 9 females, aged 18 to 68 years old with 46 years old in average. The defect sites were 3 in forefoot and 6 in midfoot and combined with different degrees of tendon and bone exposure, 17 in ankle and heel and combined with various degrees of bone exposure, 12 with ankle open injury and 5 with Achilles tendon exposure. The area of soft tissue defects ranged from 2.5 cm×1.5 cm to 16.0 cm × 6.5 cm. The width of injury was measured before surgery, and a HHD was used to detect the perforators proximal to the defect site, and then high-frequency CDU was used to locate and confirm the location of the perforator and its alignment, blood flow and diameter. The line drawn between the 2 perforators was set as the axis of flap. The donor site was assessed by a "pinching and lifting" method to determine a direct closure of donor site or to have it closed by a flap transfer. The sizes of flap were from 2.8 cm×1.5 cm to 24.0 cm×7.5 cm. Twenty-two donor sites were directly closed and 4 received flap transfers. Four flaps had sutures with the skin nerves in the recipient site. Masquelet technique was performed in 6 patients with bone defects in the surgery. Patients received outpatient reviews with 1-2 weeks of intervals in the first 2 months after surgery, and X-ray reviews per 1-2 months for those with bone implants until bone healing.Results:All flaps survived successfully without any special treatment after surgery, except 1 flap that had blood vessel congestion and showed swelling and poor blood supply to the distal flap at 24 hours after surgery. The blood vessel congestion was revised by removal of part of the suture at the tip of flap pedicle. One week later, the tip of the flap remained with a small area of necrosis, which was then healed after dressing changes. A total of 21 patients were included in postoperative follow-up with 4 months to 3 years. All of the flaps had satisfactory appearance, colour and texture, and without any ulceration. Three cases of nerve suture were also included in follow-up. According to the assessment criteria of British Medical Research Council (BMRC), the sensory recovery of the flaps was found of S 2 in 1 flap and S 3 in 2 flaps. According to the American Orthopaedic Foot and Ankle Society (AOFAS), the ankle-hindfoot function scores, there were excellent in 16 patient and good in 5 patients. Conclusion:With the assistance of ultrasound, the PPPF can be effectively used in reconstruction of soft tissue defects in ankle and foot.

Objective:To explore the effects of lower concentrations of ropivacaine on ultrasound-guided nerve block in pediatric orthopedic surgery.Methods:Using a retrospective study method, 75 children who underwent orthopedic surgery at Wu Jiang District Children′s Hospital from May 2023 to February 2024 were selected and divided into Group A (25 cases, 0.15% ropivacaine nerve block), Group B (25 cases, 0.20% ropivacaine nerve block) and Group C (25 cases, 0.25% ropivacaine nerve block). The heart rate; mean arterial pressure; onset time of anesthesia; analgesic maintenance time; recovery time of movement and sensation; child face, legs, activity, cry, consolability behavioral tool (FLACC) score at 2 h after surgery; adverse reactions incidence of postoperative local anesthetic drugs were compared.Results:There was no statistically significant difference in the physical indicators of heart rate and mean arterial pressure among the three groups ( P>0.05). As the concentration of ropivacaine increased, the onset time of anesthesia in the three groups of children was shortened: (11.04 ± 1.02) vs. (10.44 ± 1.04) and (7.16 ± 0.85) min, and the differences between the three groups were statistically significant ( P<0.05); There was no statistically significant difference in the analgesic maintenance time among the three groups ( P>0.05). As the concentration of ropivacaine increased, the recovery time of movement and sensation was increased: (194.64 ± 20.43) min vs. (207.72 ± 22.34) and (250.32 ± 30.18) min, (176.44 ± 16.18) min vs. (189.24 ± 20.66) and (224.08±29.56) min, and the differences among the three groups were statistically significant ( P<0.05). There was no statistically significant difference in FLACC scores among the three groups of patients at 2 h after surgery ( P>0.05). The total incidence of adverse reactions in Group A was lower than that in Groups B and C: 4% (1/25) vs. 24% (6/25) and 52% (13/25), and the differences among the three groups were statistically significant ( P<0.05). Conclusions:The 0.15% ropivacaine used for ultrasound-guided nerve block in pediatric orthopedic surgery can achieve good anesthesia effects with low incidence of adverse reactions, and is worthy of clinical promotion.
