ObjectiveTo clarify the perception of the work and satisfaction levels among personnel conducting unified elderly care needs assessment in Shanghai, to analyze the factors influencing their job satisfaction, and to provide references for optimizing the job satisfaction of unified elderly care needs assessment personnel in Shanghai. MethodsA survey was conducted among 93 assessment personnel randomly selected from 29 elderly care needs assessment agencies in Shanghai. The personnel’s perception of their work and their levels of job satisfaction were examined. Chi-square test and Fisher’s precision probability test were used to compare regional differences, while the two-factor theory was employed to analyze the factors influencing job satisfaction. ResultsRegarding perception of the work, 92.5% of the surveyed personnel believed their work was important. Moreover, 87.1% were interested in their assessment tasks, and 84.9% believed they made a positive contribution to the assessment work and the assessment position was in line with their personal preferences. Regarding job satisfaction, 83.9% of the participants were satisfied with their assessment work, 78.5% considered the workload appropriate, and 74.2% found the working hours suitable. Additionally, 65.6% expressed satisfaction with the level of cooperation from the assessment subjects, while 94.6% and 91.4% of the personnel were satisfied with the support provided by the assessment agencies and had a sense of belonging, respectively. Furthermore, 65.6% of the personnel expressed satisfaction with their job compensation and benefits. Hygiene factors affecting job satisfaction included salary and compensation, workload, time spent on the job and institutional support related to external assistance, job suitability, teamwork, and client cooperation (P<0.05), while motivational factors included recognition of the significance of the job, sense of achievement, interest in the job, sense of belonging, and opportunities for personal growth (P<0.05). ConclusionThe overall work cognition and satisfaction of unified elderly care needs assessment personnel in Shanghai towards their work are relatively positive. Main issues include the heavy workload and actual job subsidies not meeting expectations. It is recommended to improve the standardization of the assessment process, establish a professional team of assessment personnel, and enhance the compensation and incentive mechanisms to continuously increase staff satisfaction.

Objective:To investigate the clinical effect of autologous fat transplantation combined with hair transplantation in the treatment of hard and/or thin scalp flat scar after burn.Methods:The clinical data of patients with hard and thin scalp scar after burn admitted to the Department of Plastic Surgery of Peking University Third Hospital from January 2017 to December 2022 were retrospectively analyzed. Fat was extracted from the lower abdomen or outer thigh during the operation, and then injected into the scalp scar after standing for 15 minutes, about 0.8 ml/cm 2 under the hard and/or thin scar area, and 0.2-0.4 ml/cm 2 under the thick and soft scar area. Three months after fat transplantation, hair transplantation was performed in the scar bald area, and the transplant density was 25-35 follicular units (FUs)/cm 2 in the hard and thin scar area, and 30-40 FUs /cm 2 in the thick and soft scar area. The Vancouver scar scale (VSS) was used by two third party plastic surgeons to score the hard and/or thin scar areas of the scalp before and 3 months after scalp fat transplantation. The VSS score was expressed as M ( Q1, Q3), and the preoperative and postoperative data were compared by paired sample Wilcoxon signed rank test. During hair transplantation, the density of implanted hair in the hard and/or thin scar area were recorded. The density of living hair at these sites was measured at the last follow-up, and then the survival rate of hair (living hair density/implant hair density ×100%) was calculated. A third party plastic surgeon evaluated the extent to which scalp scars in the hair transplant area were covered, including completely covered, basically covered, partially covered. Patients’ evaluation with the surgical result was divided into very satisfied, satisfied and dissatisfied. Results:A total of 57 patients with scalp scar after burn were included in this group, including 31 males and 26 females, aged 13-47 years old. The time from scalp scarring to treatment was 8-41 years. The area of scalp scar was 17-120 cm 2, with an average of 63.3 cm 2. The fat injection volume of 57 patients was 13-75 ml. The hair transplantation was performed 3-8 months after a single fat filling procedure. The total amount of hair transplantation was 510-3 120 FUs. The total score of postoperative scar VSS was 4(3, 4), significantly lower than the preoperative score of 7(6, 7) ( W=6.70, P < 0.001). The color, thickness, blood vessel distribution and softness were significantly reduced compared with those before surgery ( P< 0.01). All patients were followed up for 12-18 months (mean, 14 months) after hair transplantation. The survival rate of hair in hard and thin scar area was 68.2% (22.7 FUs/cm 2/33.3 FUs/cm 2) to 89.7% (26.1 FUs/cm 2/29.1 FUs/cm 2), with an average of 81.3%. In 32 patients, scalp scars were completely covered. The scalp scar of 25 patients was basically covered. Twenty-nine patients were very satisfied with the result of the operation, and 28 patients were satisfied. Conclusion:The high survival rate of hair transplantation can be obtained by injecting fat under the hard and/or thin scalp scars before hair transplantation, which is an effective method to repair scalp scars.

Objective To investigate the relationship between the treatment of EGFR-TKI icotinib and the prognosis of advanced lung adenocarcinoma patients with EGFR mutation. Methods Patients with advanced lung adenocarcinoma who had EGFR19 and 21 gene mutations and were treated with EGFR-TKI icotinib were enrolled. The relationships of clinical features, EGFR gene mutation subtypes, and different sites with patients'prognosis were analyzed. Results A total of 101 patients with advanced lung adenocarcinoma were included in this study, including 58 cases (57.4%) of EGFR gene exon 19 deletion mutation (EGFR Del19) and 43 cases (42.6%) of EGFR gene exon 21 point mutation (EGFR L858R). The objective response rate was 63.4%. The mPFS and mOS were 13 months and 27 months, respectively. In addition, the mPFS and mOS of EGFR Del19 and EGFR19 mutation 746-750 were higher than those of EGFR L858R and other EGFR mutations, respectively. Meanwhile, multivariate analysis showed that the number of metastatic sites and pleural metastasis were independent influencing factors of patients'OS (

Objective:To introduce a novel method of endoscopic forehead lift and its follow-up results.Methods:In the past 7 years, 119 patients underwent endoscopic forehead lift. The parallel incisions were made on the frontalis muscle to relieve the wrinkles of the forehead. Glabella muscles were partially bluntly bitten by minimally invasive forceps. No fixator or suture was applied during the operation. Postoperative FACE-Q scales were issued to patients, and the changes of eyebrow position before and after operation were measured.Results:One week postoperatively, glabella frown and forehead wrinkles were relieved or eliminated as the swell gone. The eyebrow measurement outcome showed that the eyebrows of the patients were definitely raised after the operation. The results of FACE-Q scales showed that patients were highly satisfied with the improvement of frontal wrinkles and glabella frown wrinkles, and with the surgical outcomes and decisions. The patients thought they were averagely 7 years younger after operation. The most common complication was temporary frontal skin numbness, followed by hairline regression.Conclusions:The endoscopic forehead lift can effectively improve the forehead wrinkles and the glabella frown wrinkles which meets the demands of Chinese patients.

Objective:Dorsocervical fat pad is common in middle-aged women. Current treatments include surgical excision and liposuction. We evaluated the therapeutic effect of tumescent liposuction on dorsocervical fat pad. Anatomical study was also carried out to explore the anatomical structure and significance of dorsocervical fat pad.Methods:From Jan. 2009 to Dec. 2018, twenty-seven patients with dorsocervical fat pad were treated with tumescent liposuction in Peking University Third Hospital. Small incisions were made in bilateral scapular region and 4 mm suction cannula was applied. A female cadaver fixed with formaldehyde was dissected to investigate the structure of posterior cervical and dorsal region. The specimens were stained with HE and Masson staining.Results:14 patients were followed up for no less than 6 months, with an average follow-up time of 27 months. Patients' dorsocervical area were flat and smooth after the surgery. Patient satisfaction rate was 100% and no severe complication was reported except bruise and pain. The symptoms of dorsocervical pain in two patients were significantly improved after operation. Anatomical study showed that the dorsocervical fat pad was composed of superficial and deep layer of adipose tissue, with clear boundary between the two layers and no obvious capsule. The collagen fibers in deep layer were more and denser than those in superficial layer.Conclusions:Tumescent liposuction can effectively treat dorsocervical fat pad. The surgery outcome is ideal with little complication.Through the study of the anatomical structure of the dorsocervical fat pad, the operation method and principle of liposuction can be improved and the operation efficiency can be enhanced.

Objective:To explore the outcomes of urethra around corpora cavernosus anastomotic urethroplasty for the treatment of complex posterior urethral strictures.Methods:Between June 2008 and June 2020, 35 patients with complex posterior urethral strictures were treated using urethra rerouted under one corpora cavernosus anastomotic urethroplasty. The patients’ age was 3-54 years(mean 23.2 years), the urethral stricture or loss length was 4-7 cm(mean 5.2 cm), and 6 patients associated with urethrorectal fistula. The technique involved: ①The anterior urethra is dissected long more than 5 cm, separation of the proximal corporeal bodies, inferior pubectomy and the dissected proximal urethra.②A channel around the left crus of the penis through the inferior pubectomy is separated and urethra rerouted under left corpora cavernosus to allow a tension-free anastomosis to the proximal urethra.Results:Two patients lost follow-up; the remainder 33 patients were followed-up for 3 to 144 months(mean 37 months). Thirty-two patients could void normally(97%), The examination of maximal urinary flow rates(Q max) were taken in 21 patients, of whom Q max was 13.6-35.5 ml/s (mean 17.5 ml/s) in 7 children and 16.3-77.6 ml/s(mean 27.9 ml/s) in 14 adult patients. All 6 patients associated with urethrorectal fistula successful repaired, of these patients 1 had died of hemorrhage of brain 6 years postop. One patient developed urethral stenosis postoperatively. Continence was achieved in 29 patients, the remaining 3 patients had incontinence from mild to moderate. Conclusions:Urethra rerouted under left corpora cavernosus anastomotic urethroplasty is not only an effective surgical salvage option, with low recurrent rate for patients with complex posterior urethral strictures, but also do not cause curve and affect growth of corpora cavernosus.
