Polyetheretherketone (PEEK) as a new type of thermoplastic engineering plastic, has good biological activity, elastic modulus close to human cortical bone and radiation permeability, and has been widely used in medical field. This study aims to explore the safety and clinical efficacy of using 3D printing personalized PEEK materials to repaire scapular bone defects after bone tumor resection. A total of 6 patients who underwent the implantation of 3D printed PEEK scapular prosthesis from January 2020 to December 2021 in Yunnan Cancer Hospital were retrospectively analyzed. There were 3 males and 3 females, with age ranged from 14 to 52 years. There were 1 case of synovial sarcoma, 1 of Ewing's sarcoma, and 4 of chondrosarcoma. PEEK prosthesis was designed and fabricated based on CT data before surgery. Tumor resection and prosthesis replacement were performed under the premise of ensuring safe surgical boundaries, including 2 cases of total scapular prosthesis replacement and 4 cases of partial scapular prosthesis replacement. The operation time was 90-170 min, and the intraoperative blood loss was 100-400 ml. All 6 patients received satisfactory follow-up, with a tumor progression free survival time of 16-28 months. No tumor recurrence or metastasis was observed, and all patients survived tumor free. At last follow-up, the Constant-Murley shoulder joint score was a minimum of 62 points and a maximum of 68 points. The Japanese Orthopaedic Association's shoulder joint score was 63 points minimum and 78 points maximum. Computer-aided design 3D printing PEEK material prosthesis has certain advantages in the treatment of scapular tumor limb salvage. It has light weight, well adapted, relatively simple installation, good histocompatibility, and can obtain a better appearance and function of the shoulder joint after operation. It can become one of the options for limb salvage treatment of scapular tumor.

Objective To explore the effect of contract learning on rehabilitation training to patients with stroke . Methods According to the random number table, 120 stroke patients were randomly divided in equal number into control group and observation group. The patients in the control group were treated with conventional nursing during hospitalization and health guidance during follow-up. The patients in the observation group were given rehabilitation training according to contracted learning during the period of hospitalization and follow-up. The time was 6 months. The quality of life was compared between the two groups of patients before and after the intervention, 1 months after discharge, 6 months after discharge. Results After six months of intervention, the 7 dimensions of quality of life, including daily life ability, hand function, mobility, strength, emotion, communication and participation in the intervention group were significantly better than those of the control group (P<0.001). The 6 dimensions of quality of life, including daily life ability, hand function, mobility, strength, emotion, and communication of the control group were significantly better than before the intervention (P<0.001). Conclusion For stroke patients, the rehabilitation training under the learning contract can improve the effect of rehabilitation training so as to improve the quality of life and the prognosis.

ObjectiveTo evaluate the effect of large-spot and low-energy Q switched Nd:YAG laser on melasma,and to observe the changes of melasma lesions with confocal laser scanning microscopy (CLSM) before and after the laser treatment.MethodsTotally,45 patients aged from 24 to 48 years and diagnosed with facial melasma were included in this study,and treated with large-spot and low-energy Q switched Nd:YAG once a week for 10 or more sessions.CLSM was used to estimate the melanin content in melasma lesions before each irradiation and after the last irradiation.ResultsAmong the 45 patients,8 ( 17.78％ ) were nearly cured,25 (55.56％) markedly improved,11 (24.44％) improved,and only 1 (2.22％) unimproved after the laser irradiation.The total response rate was 73.33％.As CLSM showed,there was an increment in melanin granules in melasma lesions compared with the normal skin surrounding melasma lesions,but a reduction in melanin granules was induced by the laser treatment in melasma lesions.ConclusionsLarge-spot and lowenergy Q switched Nd∶YAG laser is substantially effective and highly safe for the treatment of melasma,and CLSM can be used to evaluate the therapeutic effect of laser on melasma.

Objective To introduce a new method for correction of epicanthal folds, which could avoid obvious scar in medial canthus. Methods First, through upper and lower palpebral margin incisions, the connective and orbicularis oculi muscle dense fibers underlying epicanthal folds as well as the superficial head of medial canthal ligament were thoroughly released and excised. After repositioning the medial canthus, the redundant skin tissue was removed and then the incisions closed. Results 122 epicanthoplasties had been performed. Postsurgical scars were invisible in all cases. All patients were satisfied with operation results. No recurrence of epicanthal fold was observed. Conclusions The introduced method has advantages in avoiding scar formation and is an especially suitable approach for epicanthoplasty in Asian patients.

Objective To observe the influence of emergency PCI in different time windows to cardiac scar and cardiac function after myocardial infarction. Methods One hundred and twenty-seven patients with acute myocardial infarction, who were treated in different time windows by emergency PCI, were enrolled into this study. The cases were divided into two groups according to the time when they took PCI after onset;group 3 hPCI included 66 patients had PCI at 3 h after onset and group 6 hPCI included 61 patients had PCI at 6 h. At 4th, 8th and 12th weeks, the fragmented QRS (fQRS) were observed by twelve synchronization cardiogram; ventricle wall movement strain rate were determined by cardiac speckle tracking imaging;left ventricular ejection fraction (LVEF)were measured by cardiac ultrasound to evaluate cardiac events and cardiac function after myocardial infarction. Results At 4th,8th and 12th weeks,the fQRS positive leads were significantly more in 6 hPCI group than 3 hPCI group ( P ＜ 0. 05 respectively ) . The ventricle wall movements strain rate and LVEF improved significantly in 3 hPCI group compared with 6 hPCI group (P ＜ 0. 05 ). Conclusions The earlier emergency PCI treatment was applied and the earlier the"criminal"blood vessels were opened ,the more ischemic myocardial cells were restored. Combination use of fQRS、 STI and LVEF examination could improve the diagnosis of cardiac scar formation and direct protective therapy.

Objective To investigate the ability of single photon emission computed tomography (SPECT) and MRI in detecting skull-base invasion in nasopharyngeal carcinoma. Methods Sixty-one patients with nasopharyngeal carcinoma received whole body and skull-base tomography SPECT, and nasopharynx and skull-base MRI before radiotherapy. The results were double-blind compared and evaluated. Results The overall positive rates of skull-base invasion detected by SPECT and MRI were 51% and 46% (P=0.508). In paitents with headache, cranial nerve palsy or both, the rates were 83% and 86% (P=1.000) ,80% and 80% (P=1.000), 88% and 94% (P=1.000), respectively. In patients with T1+T2 and T3+T4lesions,the rates were 22% and 0(P=0.031) ,74% and 82% (P=0.250) ,repectively. In patients with N0+N1and N2+N3lesions,they were 50% and 48% (P=1.000) ,53% and 40% (P=0.500) ,respectively. The conformation rate between SPECT and MRI was 85%. Binary Logistic regression analysis showed that T stage was a risk factor for positive SPECT(χ2=4.23,P=0.040, OR=3.04). Headache tended to be a risk factor for both positive SPECT and positive MRI (χ2=3.13, P=0.077, OR=4.54;χ2=3.64,P=0.056,OR=12.00). Conclusions The detection sensitivity of SPECT in skull-base invasion in nasopharyngeal carcinoma is equivalent to that of MRI. The consistency between SPECT and MRI is good. Moreover, there is a good correlation between SPECT and symptoms, signs and stage. SPECT of skullbase tomography is necessary for patients with severe headache, negative CT and those who can not receive MRI. When SPECT result is positive,skull-base should be considered to be invaded and should be defined as gross tumor volume in radiotherapy planning.
