Polygonati Rhizoma demonstrates significant potential for addressing both chronic and hidden hunger. The supply of high-quality seedlings is a primary factor influencing the development of the Polygonati Rhizoma industry. Warm water soaking is often used in agriculture to promote the rapid germination of seeds, while its application and molecular mechanism in Polygonati Rhizoma have not been reported. To rapidly obtain high-quality seedlings, this study treated Polygonatum kingianum var. grandifolium seeds with sand storage at low temperatures, warm water soaking, and cultivation temperature gradients. The results showed that the culture at 25 ℃ or sand storage at 4 ℃ for 2 months rapidly broke the seed dormancy of P. kingianum var. grandifolium, while the culture at 20 ℃ or sand storage at 4 ℃ for 1 month failed to break the seed dormancy. Soaking seeds in 60 ℃ warm water further increased the germination rate, germination potential, and germination index. Specifically, the seeds soaked at 60 ℃ and cultured at 25 ℃ without sand storage treatment(Aa25) achieved a germination rate of 78. 67%±1. 53% on day 42 and 83. 40%±4. 63% on day 77. The seeds pretreated with sand storage at 4 ℃ for 2 months, soaked in 60 ℃ water, and then cultured at 25 ℃ achieved a germination rate comparable to that of Aa25 on day 77. Transcriptomic analysis indicated that warm water soaking might promote germination by triggering reactive oxygen species( ROS), inducing the expression of heat shock factors( HSFs) and heat shock proteins( HSPs), which accelerated DNA replication, transcript maturation, translation, and processing, thereby facilitating the accumulation and turnover of genetic materials. According to the results of indoor controlled experiments and field practices, maintaining a germination and seedling cultivation environment at approximately 25 ℃ was crucial for the one-year seedling cultivation of P. kingianum var. grandifolium.

Objective:To explore the application of game-based teaching combined with Jeffries simulation teaching in training orthopedic trauma nursing interns.Methods:Totally 120 intern nurses who received orthopedic trauma nursing training from 2021 to 2023 were selected. They were divided into two groups according to their start dates, with 60 nurses in each group. The control group (started before December 2022) adopted routine teaching, whereas the observation group received game-based teaching combined with Jeffries simulation teaching. The assessment results, core competence [Competency Inventory for Registered Nurse (CIRN)], and learning enthusiasm [Active Learning Scale (ALS)] were compared both between the groups and within each group before and after the training. The course experience [Course Experience Questionnaire (CEQ)] of the trainees after training was recorded.Results:After the internship, the theoretical exam scores [(89.64±6.73) vs. (83.71±6.20)], practical operation scores [(80.82±5.94) vs. (75.61±5.73)], CIRN scores [(180.69±7.61) vs. (157.33±6.83)], and ALS scores [(89.48±6.83) vs. (73.22±6.25)] of two groups of nursing students increased compared to their scores before the internship, and the observation group showed significantly higher scores than the control group ( P<0.05). After the internship, the CEQ score was higher in the observation group than in the control group [(49.65±2.58) vs. (36.57±1.94)]. Conclusions:In the training of orthopedic trauma nursing interns, game-based teaching combined with Jeffries simulation teaching can not only improve course experience and learning enthusiasm, but also enhance the assessment results, core competence, and critical thinking.

Objective:To study the effect of blood volume feedback control system on improving intradialytic-hypotension (IDH) in maintenance hemodialysis (MHD) patients.Methods:It was a prospective cohort study. Thirty MHD patients with recurrent IDH in the Dialysis Center of the First Affiliated Hospital of Zhejiang University School of Medicine from March 2021 to March 2022 were selected. A self-control study was conducted in MHD patients. The patients were treated with routine hemodialysis in both baseline phase (A1) and reversal phase (A2), while with hemodialysis under the blood volume feedback control system in intervention phase (B). Each phase lasted for 4 weeks (12 hemodialysis sessions). The average occurrences of IDH and IDH-related adverse events (IDH-RAE, stopping dehydration for more than 10 minutes or getting off the hemodialysis machine 10 minutes earlier due to IDH) of each patient between phase A1, B, and A2 were calculated and compared. In a total of 1 080 dialysis records, a logistic regression analysis model was established with age, sex and intervention as independent variables and with the occurrence of IDH-RAE as the outcome.Results:A total of 30 eligible patients were included in the study, including 14 males (46.7%) and 16 females (53.3%), aged 63.0 (56.5, 72.5) years old, with a median dialysis age of 84.0 (37.2, 120.0) months. The average times of IDH in 30 MHD patients decreased from 1.17 (0.83, 1.67) in stage A1 (before intervention) to 0.33 (0.25, 0.58) in stage B (after intervention) ( P<0.05). The frequency of IDH-RAE decreased significantly from 0.29 (0.19, 0.47) in stage A1 to 0.17 (0,0.25) in stage B ( P<0.05). Logistic regression analysis results indicated that the use of blood volume feedback control system reduced the risk of IDH-RAE by 53% ( OR=0.47, 95% CI 0.34-0.64, P<0.001). Conclusions:The application of blood volume feedback control system can effectively reduce the occurrences of IDH and the risk of IDH-RAE in MHD patients.

Objective:To analyze the clinical effect of hyaluronidase injection through the facial artery in the treatment of vascular embolism such as skin ulceration and necrosis after cosmetic injection.Methods:Hyaluronidase was injected through facial artery in 13 patients who were diagnosed with vascular embolism after facial injection from January 2019 to May 2020. The facial artery was punctured with 22-gauge arterial blood collection needle or 19/23-gauge disposable venous infusion needle. The angle between the needle body and the skin varies depending on the patients’ weight, ranged 30°-45°. The needle was advanced slowly and pushed forward by 2-3 mm when blood backflow appeared in the needle core. After confirming the successful puncture of the facial artery, 0.5-1.5 ml hyaluronidase was slowly injected into the facial artery. The time of skin relaxation, tenderness relief, ulcer healing and wound recovery were observed. The pigmentation was observed and the Vancouver Scar Scale (VSS) was used to score the scars after 3-12 months.Results:A toal of 13 patients with vascular complications of hyaluronidase filler were retrospectively reviewed. The patients were 18-45-year-old(mean age, 35 years) and received hyaluronidase filler at private clinics. There were 12 women and 1 man. The time from onset to visit was 14 h to 4 d, with an average time of 2.5 d. Hyaluronidase was most commonly injected into the nasolabial folds (54%, 7 of 13). The second-ranked area is the nasalroot (23%, 3 of 13). These patients had skin swelling, necrosis, ecchymosis or black scabs during or after hyaluronidase injection. Some patients showed skin lesions combined with oral ulcer. After percutaneous facial arterial hyaluronidase injection, the local skin tissue injuries of the 13 patients were improved in time. The time of skin relaxation was (0.77±0.25) d, the time of tenderness relief was (1.23±0.64) d, the time of ulcer healing was (3.14±0.64) d and the time of wound recovery was (5.85±0.86) d. Patients were followed up for 3-12 months, with an average of 7 months. One patient had slight scar (VSS score of 1), two patients had only mild pigmentation (VSS score of 0), and the other ten patients had no scar and pigmentation (VSS score of 0).Conclusions:It is effective to improve local microcirculation and reduce skin tissue injury after percutaneous facial artery hyaluronidase injection in the treatment of skin injury caused by facial filler injection.

Objective: To compare the measurement accuracy of two⁃dimensional (2D) photography and three⁃di⁃mensional (3D) photography in the analysis of the asymmetric appearance of children with cleft lip and palate and the influence of the severity of asymmetric deformity on the accuracy of facial measurement to guide clinical measurement work Methods: Children with unilateral cleft lip were enrolled in this prospective study. Seven parameters⁃⁃the devia⁃tion of the pronasale, subnasale, and labrale superius, as well as the cleft/noncleft ratio of the width of nostrils, length and height of lateral lips and height of columella⁃were measured with Vernier calipers as the gold standard. Traditional 2D photography and 3D stereophotogrammetry photos were taken and measured. The extent of cleft malformation is indi⁃cated by the ratio of the cleft side to the noncleft side. The error size is represented by the ratio difference between two⁃dimensional photography or stereophotogrammetry with the ratio of the gold standard Results: Thirteen patients were eventually recruited. The measurement results of the ratio of lateral lip height by 2D photography tended to be larger (P＝0.019), and the measurement results of the ratio of columella height tended to be smaller (P＝0.008). The measure⁃ment results of the deviation of the subnasale by stereophotogrammetry tended to be smaller (P＝0.003). The pronasale deviation (P＝0.022) with two⁃dimensional photography, the deviation of the labrale superius (P＝0.025) and the ratio of lateral lip length (P＝0.036) with stereophotogrammetry had a significant negative correlation with the extent of cleft malformation Conclusion Both two⁃dimensional photography and stereophotogrammetry have errors and biases that underexaggerate or overexaggerate the extent of cleft malformation, and some errors may increase with the decrease in the extent of cleft malformation. When applying two⁃dimensional and three⁃dimensional photography to analyze cleft lip and palate deformities, these biases should be considered to evaluate the face more objectively
