Objective To investigate the method and influencing factors of laser treatment in the removal of complicated tattoos.Methods 1280 patients with tattoos were treated by Versapulse four wavelength laser system.According to different colors,we selected different energy parameters and wavelength.Results All the 1280 patients got satisfied results after the therapy. The response was mainly related with the composition of their tattoos' color, as well as the proper choosing of laser wavelength and parameter.Conclusions According to feature of different tattoos,selecting reasonable wavelength and therapeutic parameters to treat the complicated tattoos can obtain better efficacy.

Objective To investigate the therapeutic methods for hypertrophy of nasal tip so as to create an aesthetic shape of nasal tip. Methods The “seagull-wing incision”was used in all patients. According to various nasal tip contours, trimming of soft tissues and reconstruction of alar cartilage were preformed simultaneously. Excessive soft tissue between skin and alar cartilage was removed; after exposing the domal segment of the alar cartilage, cartilage was resected from lateral crus to middle crus with a width of 0.2 cm marginal lateral crus was left. The shape of nasal tip was recontoured by middle crus suture technique. Others deformities of nose were corrected then: 10 patients with flat and low nasal tip were operated for nasal augmentation; 9 patients with thickening nasal wing were operated for thinning rim; 3 patients with wide bases of nasal wing were operated for shortening width through intraoral approach and one patient with broad nasal bone was operated with osteotome, infractured and displaced in the midline. An exteral splint was placed over the tape for 5-7 days postoperatively. Results Since 1995, follow-up for 3 to 24 months showed that 25 cases had achieved satisfactory cosmetic effects without secondary deformity except 3 early cases. Conclusion Trimming of soft tissues and reconstruction of alar cartilage are effective methods for correction of hypertrophy of nasal tip.

Objective To study the Diagnosis and treatment of thyroglossal duct cyst or fistula. Methods The clinical data of 67 patients with thyroglossal duct cyst or fistula treated by surgery were analyzed retrospectively. Results The diagnosis rate preoperatively was 92.5% and the accuracy diagnosis rate by B type ultrasonography was 96.1%; all cases were treated by operation, of them, 14 cases underwent simple cyst resection, 12 with resection of partial periosteum of hyoid and 41 with resection of middle segment of hyoid( Sistrunk's operation ). 54 cases were followed up, recurrence in cases with cyst was 4 of 43 (9.3%) and recurrence in cases with fistula was 2 of 11(18.2%)respectively. Conclusion Ultrasonography shows certain characteristics and clinical value to diagnose and distinguish thyroglossal duct cyst. Postoperative recurrence is due to the selection of operation procedures and control of infection of focus. The Sistrunk's operation properly performed previou to cyst infection should reduce recurrence rate markedly.

Objective To investigate the effects of three-dimensional titanium mesh repair on cerebral perfusion,intracranial pressure and nerve function after decompression with bone flap.Methods From October 2015 to October 2018,132 hypertensive cerebral hemorrhage patients of bone disc decompression in the Fifth People's Hospital of Jinan were selected and divided into observation group (66 cases) and control group(66 cases) by double blind random method.The observation group received three-dimensional titanium mesh repair at 24 ～ 42 d after bone disc decompression surgery.The control group received three-dimensional titanium mesh repair at 90 ～ 150 d(3 ～ 5 months) after surgery.The changes of operation,cerebral perfusion,intracranial pressure and nerve function were compared between the two groups.Results The operative time,blood loss and free time of the flap in the observation group were (92.5 ± 12.4) min,(354.3 ± 17.5) mL and (13.2 ± 3.1) min,respectively,which were shorter or less than those in the control group [(142.8 ± 15.3) min,(518.3 ± 22.3) mL and (38.3 ± 4.3) min],the differences between the two groups were statistically significant (t=4.745,6.831,4.963,all P ＜ 0.05).After treatment,the abnormal indices of intracranial pressure and cerebral perfusion in the observation group were (0.1 ±0.0) and(0.2 ± 0.1),respectively,which were lower than those in the control group [(0.2 ± 0.1),(0.3 ± 0.1)] (t =3.657,2.579,all P ＜0.05).There were statistically significant differences in neurological deficit scores between the two groups at different time points(all P ＜0.05).The incidence of treatment complications in the observation group was 10.94％ (7/64),which was significantly lower than that in the control group [38.7％ (24/62)] (x2 =14.094,P ＜ 0.05).Conclusion Three-dimensional titanium mesh repair is helpful to shorten the operation time,restore the intracranial pressure on the affected side,improve the abnormal cerebral perfusion,and reduce the neurological damage in patients with hypertensive cerebral hemorrhage.

ObjectiveTo investigate the current situation of rehabilitation therapists' work, and analyze the factors related to their career development and transformation. MethodsFrom September, 2022 to January, 2023, 153 rehabilitation therapists in Weifang were investigated with a cross-sectional questionnaire, using general questionnaire, Job Satisfaction Scale for Grassroots Health Technicians, Social Responsibility Scale, Job Role and Identity Inventory, and Employee Turnover Scale. ResultsThe majority of rehabilitation therapists interviewed were male (52.28%), under 35 years old (88.24%), with a bachelor's degree (77.78%), income less than 5 000 yuan a month (46.40%), and less than five years of service (48.36%). The work time was (7.78±0.84) hours a day, (5.39±0.51) days a week. The favorable rate of the physical environment of work was 67.32%, and the favorable rate of the interpersonal relationship environment of work was 80.39%. The score of professional identity was (3.61±0.84), the score of job satisfaction was (3.62±0.97), the score of social responsibility was (3.53±0.79), and the score of turnover was (2.39±1.10). Education level, job satisfaction, and social responsibility were the main factors related to the employee turnover (P < 0.05). ConclusionThe overall educational level of rehabilitation therapists is relatively low, and the human resource structure needs to be optimized. There is a significant difference between academic education and continuing education, and career development needs to be improved. The main factors related to career development and transformation are education level, job satisfaction, and social responsibility.
