Objective:To explore the effect of auricular acupressure therapy on postoperative pain and early rehabilitation of patients with total knee arthroplasty.Methods:From March to June 2021, 68 patients who underwent unilateral total knee arthroplasty for the first time under general anesthesia combined with peripheral nerve block in Liaocheng People's Hospital were selected by convenient sampling. According to the random number method, the patients were divided into observation group (35 cases) and control group (33 cases) . Both groups received routine pain management and early postoperative rehabilitation nursing after operation, and the Chinese medicine doctors pasted the Wangbuliuxing seed adhesive tape at the auricular points one day before operation. The control group did not take any pressing operation. The observation group was pressed at the time of 1 day before operation to 3 days after operation, 3 times a day. The pressing frequency was 60 times/min, and the pressing time was 1 minute per acupoint. The dosage of analgesics used immediately after leaving the Anesthesia Recovery Room and at 4, 24, 48 and 72 hours after operation, as well as the visual analog pain scores of rest and activity at each follow-up time point were recorded and compared between the two groups. The knee range of motion of the two groups on the second, the fourth and seventh days after operation was compared.Results:The dosage of patient-controlled intravenous analgesia analgesics in the observation group were lower than those in the control group at 24, 48 and 72 hours after operation, with statistically significant differences ( P<0.05) . The pain score of the patients in the observation group at rest 24 hours after operation was lower than that in the control group, and the pain scores of the patients in the active state at 24, 48 and 72 hours after operation were lower than those in the control group, and the differences were statistically significant ( P<0.05) . The knee range of motion in the observation group were higher than those in the control group on the second, fourth and seventh days after operation, and the differences were statistically significant ( P<0.05) . Conclusions:Auricular acupressure therapy can reduce the dosage of analgesics used after total knee arthroplasty, relieve the degree of pain, and promote the early recovery of patients.

Objective:To establish an automatic planning method using volumetric-modulated arc therapy (VMAT) for primary liver cancer (PLC) radiotherapy based on predicting the feasibility dose-volume histogram (DVH) and evaluate its performance.Methods:Ten patients with PLC were randomly chosen in this retrospective study. Pinnacle Auto-Planning was used to design the VMAT automatic plan, and the feasibility DVH curve was obtained through the PlanIQ dose prediction, and the initial optimization objectives of the automatic plan were set according to the displayed feasible objectives interval. The plans were accessed according to dosimetric parameters of the planning target volume and organs at risk as well as the monitor units. All patients′ automatic plans were compared with clinically accepted manual plans by using the paired t-test. Results:There was no significant difference of the planning target volume D 2%, D 98%, D mean or homogeneity index between the automatic and manual plans ((58.55±2.81) Gy vs.(57.98±4.17) Gy, (47.15±1.58) Gy vs.(47.82±1.38) Gy, (53.14±0.95) Gy vs.(53.44±1.67) Gy and 1.15±0.05 vs. 1.14±0.07, all P>0.05). The planning target volume conformity index of the manual plan was slightly higher than that of the automatic plan (0.77±0.08 vs. 0.69±0.06, P<0.05). The mean doses of normal liver, V 30Gy, V 20Gy, V 10Gy, V 5Gy and V< 5Gy of the automatic plan were significantly better than those of the manual plan ((26.68±11.13)% vs.(28.00±10.95)%, (29.96±11.50)% vs.(31.89±11.51)%, (34.88±11.51)% vs.(38.66±11.67)%, (45.38±12.40)% vs.(50.74±13.56)%, and (628.52±191.80) cm 3vs.(563.15±188.39) cm 3, all P<0.05). The mean doses of the small intestine, the duodenum, and the heart, as well as lung V 10 of the automatic plan were significantly less than those of the manual plan ((1.83±2.17) Gy vs.(2.37±2.81) Gy, (9.15±9.36) Gy vs.(11.18±10.49) Gy, and (5.44±3.10) Gy vs.(6.25±3.26) Gy, as well as (12.70±7.08)% vs.(14.47±8.11)%, all P<0.05). Monitor units did not significantly differ between two plans ((710.67±163.72) MU vs.(707.53±155.89) MU, P>0.05). Conclusions:The automatic planning method using VMAT for PLC radiotherapy based on predicting the feasibility DVH enhances the quality for PLC plans, especially in terms of normal liver sparing. Besides, it also has advantages for the protection of the intestine, whole lung and heart.

Objective:To investigate and analyze the current situation and influencing factors of professional decision-making self-efficacy of male nurses.Methods:Convenience sampling was used to select 133 male nurses from September to October 2020 in Shenzhen City as the research objects. The Self-efficacy Scale for Career Decision-making was used to conduct self-evaluation, career information collection, career goal selection, career planning formulation, and job-selection problem resolution.Results:Attitudes towards nursing majors, academic qualifications, reasons for applying for nursing majors, monthly family income, whether it is an only child, family residence, work status, number of job changes, mother′s education level, and married or not were the factors that affect male nurses′ professional self-efficacy ( t values were -1.989-12.523, F values were 7.476-325.316, P<0.05 or 0.01). Conclusion:Career decision-making self-efficacy has a good guiding role in the career selection, development and planning of male nurses. Medical units should formulate reasonable training methods or related training for new male nurses entering the clinic, so as to increase male nurses′ recognition of their occupations, thereby enhancing them Career decision-making self-efficacy.
