Objective: To investigate the humanistic care consciousness and ability of outpatient and emergency nurses in tertiary Grade A hospitals in Zhengzhou City. Methods: In June 2021, a total of 345 outpatient and emergency nurses from 6 tertiary Grade A hospitals in Zhengzhou City were selected as the survey objects by random number table method. The humanistic care ability of outpatient and emergency nurses was investigated. Multiple linear regression analysis was used to analyze the related factors influencing the humanistic care ability of outpatient and emergency nurses. Results: The total score of humanistic care ability of outpatient and emergency nurses in Zhengzhou tertiary Grade A hospital was (194.18±30.53). The scores of humanistic care ability of outpatient and emergency nurses with different gender, age, educational background, professional title, length of service, night shift frequency, marital status, children's status, employment patterns and average monthly household income were significantly different (P<0.05). Regression analysis showed that education background, length of service, professional title and night shift frequency were independent influencing factors for outpatient and emergency nurses' humanistic care ability (β=0.243, 0.139, 0.163, -0.126, P<0.05) . Conclusion: At present, the humanistic care ability of outpatient and emergency nurses in tertiary Grade A hospitals in Zhengzhou City is still low. Education, length of service, professional title and night shift frequency are independent influencing factors affecting the humanistic care ability of nurses.

Objective: To investigate the surgical indications and perioperative clinical outcomes of pelvic exenteration (PE) for locally advanced, recurrent pelvic malignancies and complex pelvic fistulas. Methods: This was a descriptive study.The indications for performing PE were: (1) locally advanced, recurrent pelvic malignancy or complex pelvic fistula diagnosed preoperatively by imaging and pathological examination of a biopsy; (2)preoperative agreement by a multi-disciplinary team that non-surgical and conventional surgical treatment had failed and PE was required; and (3) findings on intraoperative exploration confirming this conclusion.Contraindications to this surgical procedure comprised cardiac and respiratory dysfunction, poor nutritional status,and mental state too poor to tolerate the procedure.Clinical data of 141 patients who met the above criteria, had undergone PE in the Sixth Affiliated Hospital of Sun Yat-sen University from January 2018 to September 2022, had complete perioperative clinical data, and had given written informed consent to the procedure were collected,and the operation,relevant perioperative variables, postoperative pathological findings (curative resection), and early postoperative complications were analyzed. Results: Of the 141 included patients, 43 (30.5%) had primary malignancies, 61 (43.3%) recurrent malignancies, 28 (19.9%) complex fistulas after radical resection of malignancies,and nine (6.4%)complex fistulas caused by benign disease. There were 79 cases (56.0%) of gastrointestinal tumors, 30 cases (21.3%) of reproductive tumors, 16 cases (11.3%) of urinary tumors, and 7 cases (5.0%) of other tumors such mesenchymal tissue tumors. Among the 104 patients with primary and recurrent malignancies, 15 patients with severe complications of pelvic perineum of advanced tumors were planned to undergo palliative PE surgery for symptom relief after preoperative assessment of multidisciplinary team; the other 89 patients were evaluated for radical PE surgery. All surgeries were successfully completed. Total PE was performed on 73 patients (51.8%),anterior PE on 22 (15.6%),and posterior PE in 46 (32.6%). The median operative time was 576 (453,679) minutes, median intraoperative blood loss 500 (200, 1 200) ml, and median hospital stay 17 (13.0,30.5)days.There were no intraoperative deaths. Of the 89 patients evaluated for radical PE surgery, the radical R0 resection was achieved in 64 (71.9%) of them, R1 resection in 23 (25.8%), and R2 resection in two (2.2%). One or more postoperative complications occurred in 85 cases (60.3%), 32 (22.7%)of which were Clavien-Dindo grade III and above.One patient (0.7%)died during the perioperative period. Conclusion: PE is a valid option for treating locally advanced or recurrent pelvic malignancies and complex pelvic fistulas.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

Objective:To investigate the clinical effect of water-jet excision combined with skin graft in the treatment of giant congenital melanotic nevus.Methods:The patients with giant nevus who were admitted to the Department of Plastic Surgery, Chinese PLA General Hospital from January 2015 to May 2019 were retrospectively analyzed. All patients were treated by layer-by-layer cutting of giant nevus with water-jet, preserving the subcutaneous fascial layer and part of the dermis as much as possible, then following by skin graft transplantation. The patients visited the hospital 1-2 years after operation. The postoperative scar of skin graft area was scored by Patient and Observer Scar Assessment Scale (POSAS), and the satisfaction of skin graft area was evaluated by digital scoring method (1-10 points). The recurrence of nevus pigmentosus and implantation metastasis were observed. Descriptive method were used for statistical analysis.Results:A total of 7 children were included, 2 males and 5 females, aged 4 to 14 years. There were 3 cases on the trunk and 4 cases on the extremities. Giant nevi accounted for (7.4 ± 3.1)% of the body surface area. Then skin graft survived well after surgery in all 7 children. During the 1-year follow-up after operation, the POSAS score of skin graft scar showed that the sum of 1-3 points in the scores of scar pain, itching, hardness and thickness by the patients or their families was 6, 4, 4 and 5 cases, respectively, and the sum of 4-10 points in the pigmentation and irregularity was 5 and 5 cases, respectively. None of the 7 patients had functional limitation in the skin graft area; the physicians’, scores for vascularity, pigmentation, thickness, and flexibility of the scars in the skin graft area were low, with a sum of 6, 3, 4, and 4 for the number of cases with 1-3 points and 2 and 4 for the number of cases with 1-3 points and 4-6 points in the flatness score, respectively. The satisfaction of both doctors and patients (sum of 7-10 points) was 4 and 5 cases, respectively. 7 cases were reexamined 1 year after operation, with recurrence of 2 punctate nevus pigmentosus(less than 1 mm in diameter) in only one case. No implantation metastasis in the skin graft area of nevus pigmentosus happened.Conclusions:Water-jet excision combined with skin graft in the treatment of giant nevus is simple and only one procedure required. The donor site only needs to cut a split-thickness skin graft. The postoperative scar is not obvious and the skin elasticity is better. Patients were relatively satisfied with the postoperative effect. It is suitable for the resection of nevus pigmentosus in the trunk especially the nevus pigmentosus with good texture and lighter color but not for the lesion at articular area of limbs.
