Objective:To investigate the clinical efficacy of stamp skin grafting combined with vacuum sealing drainage in the treatment of diabetic foot ulcers.Methods:A prospective study was conducted involving 80 patients with diabetic foot ulcers admitted to Lishui Central Hospital from January 2020 to December 2022. The patients were divided into an observation group and a control group, with 40 patients in each group, using a random number table method. The control group received treatment with vacuum-sealing drainage technology, while the observation group was treated with stamp skin grafting combined with vacuum sealing drainage. The two groups were compared based on several perioperative indicators, including wound healing time, length of hospital stay, number of dressing changes, and progress of granulation tissue growth. Pain levels were assessed using the Visual Analog Scale. Additionally, dorsalis pedis blood flow dynamics were evaluated, focusing on the diameter of the dorsalis pedis artery and arterial blood flow velocity. Foot function was assessed using the Maryland Foot Function Scale. The occurrence of postoperative complications was recorded.Results:The wound healing time and length of hospital stay in the observation group were (21.54 ± 5.32) days and (27.08 ± 5.97) days, respectively, which were significantly shorter than those in the control group [(26.69 ± 5.66) days, (31.49 ± 6.80) days, t = 4.19, 3.08, both P < 0.05]. The number of dressing changes in the observation group was (5.11 ± 1.14), which was significantly fewer than that in the control group [(8.07 ± 1.59), t = 9.56, P < 0.001]. The progress of granulation tissue growth in the observation group [(3.12 ± 0.64) mm] was faster that in the control group [(2.09 ± 0.48) mm, t = 8.14, P < 0.001]. At 1, 2, and 3 months post-surgery, the Visual Analog Scale scores for the observation group were (3.52 ± 0.65), (2.33 ± 0.42), and (1.40 ± 0.26), respectively, which were significantly lower than those in the control group [(3.96 ± 0.71), (2.74 ± 0.44), (1.78 ± 0.34), t = 2.89, 4.26, 5.615, all P < 0.05). At 3 months post-surgery, the diameter of the dorsalis pedis artery and arterial blood flow velocity in the observation group were (2.64 ± 0.44) mm and (36.42 ± 6.28) cm/s, respectively, which were greater than those in control group [(2.18 ± 0.41) mm, (30.97 ± 5.33) cm/s, t = 4.83, 4.18, both P < 0.001]. At 3 months post-surgery, the scores for pain, foot function, appearance, and range of motion in the observation group were (39.28 ± 6.70), (48.10 ± 7.22), (7.94 ± 1.54), and (12.15 ± 2.35), respectively, which were significantly higher than those in the control group [(33.46 ± 6.89), (43.08 ± 6.68), (5.38 ± 1.06), and (10.69 ± 2.16), t = 3.83, 3.22, 8.66, 2.89, all P < 0.05]. There was no statistically significant difference in the overall incidence of postoperative complications, including skin flap necrosis/dislocation, hematoma accumulation, infection, and ulcer recurrence, between the two groups ( P > 0.05). Conclusions:Stamp skin grafting combined with vacuum sealing drainage can significantly accelerate wound healing in patients with diabetic foot ulcers, reduce postoperative pain, improve dorsalis pedis blood flow dynamics, enhance foot function, and demonstrate good safety.

Prostate cancer is the most common cancer among men and the fifth leading cause of cancer-related death among men worldwide. Gastrin-releasing peptide receptor (GRPR) is an important complementary target of prostate specific membrane antigen (PSMA) and a key target for prostate cancer diagnosis and treatment. Radionuclide labeled bombesin (BBN) analogues can accurately target overexpressed GRPR in tumor cells, thus providing early diagnosis and treatment of prostate cancer. In this review, we focus on the studies of 99Tc m, 111In, 68Ga, 64Cu, 18F, and 177Lu nuclide-labeled BBN analogues for diagnosis and peptide receptor radionuclide therapy.

Objective To investigate the self-care agency in disabled elders of community and to explore effects of medical care and nursing service integration on self-care agency in disabled elders with different degrees of disability in community. Methods We traced and investigated a total of 42 disabled elders signed medical care and nursing service integration with a community. The self-care agency was compared with the Chinese Version of the Self-care Ability Scale for the Elderly (SASE-CHI) before and six months after service objects accepting services. Results The average of self-care ability of community disabled elders was (48.69±12.11) with a low level. Six months after accepting medical care and nursing service integration, the score of self-care ability of disabled elders increased along with (53.07±8.68) in total score of self-care ability, (21.38±3.76) in objective dimension and (25.62±4.39) in skill dimension. There were significant differences in scores of self-care ability compared before and after accepting service (t=-2.346,-2.592, -2.731;P<0.05). There were small changes in elders with mild disability before and after accepting services (P>0.05). The total score of self-care ability and score of skill dimension increased in elders with moderate and severe ability after accepting services, the differences were statistically significant (P<0.05). Conclusions The self-care ability of community disabled elders is in a low level. The medical care and nursing service integration can improve self-care ability of community disabled elders. However, there is great room to upgrade.

Objective To evaluate the health problems existed in the disabled elderly in nursing homes in Zhejiang province and assess the knowledge, behavior and status of each existed health problem. Methods By cross-sectional study, a total of 50 disabled elderly in four nursing homes in Zhejiang province were assessed. Results The common health problems of the disabled elderly in nursing homes were personal care, oral health, social contact, physical activity, vision, neuro-musculo-skeletal function, mental health, cognition, medication regimen, and pain. Among the common health problems, the knowledge, behavior and status in personal care, oral health, mental health, and pain were more severer than others. Conclusions A lot of health problems exist among the disabled elderly in nursing homes. A comprehensive and targeted care should be used to improve patients′health.
