Objective To make a summary of the clinical application and cooperation of piezosurgery in jaw bone tumour operation. Methods 64 patients with jaw bone tumour were selected since 2007 and were divided into the piezosurgery group and the routine group, they used piezosurgery and routine osteotome respectively. Feelings during operation, operation time, hemorrhage, postoperative reaction and complication were observed and compared. Results Discomfort and hemorrhage during operation was lighter, but operation was longer in the piezosurgery group compared with the routine group. Complications such as postoperative infection, hemorrhage and nerve damage did not occurred. Conclusions Application of piezosurgery in jaw bone tumor operation can increase comfort degree and reduce hemorrhage, it requires proficiency in operation procedures and master key aspects of nursing, so that can cooperate well.

Objective To investigate the distribution and antimicrobial resistance profile of clinical gram-negative bacterial isolates in the First Afifliated Hospital of Nanjing Medical University during 2014.Methods Bacteria identiifcation was performed by API system or the VITEK-2 Compact automatic identiifcation system. Disk diffusion susceptibility testing or VITEK-2 Compact automatic identification system was used to determine the susceptibility to antimicrobial agents. All data were analyzed using WHONET 5.6 software.Results Among the total 7 931 clinical isolates in 2014, gram-negative bacteria accounted for 64.2% (5 088/7 931). The top three pathogens wereE. coli,A. baumannii andK. pneumoniae. Notably, during the year 2014, 195 strains of carbapenem-resistantEnterobacteriaceaewere isolated, about 6.9% of all theEnterobacteriaceae isolates. Meanwhile, 613 (66.5%) strains of multiple drug resistantA. baumannii and 197 (28.7%) strains of multiple drug resistantP. aeruginosa were isolated.Conclusion During the year 2014, the resistance of the gram-negative bacteria in this hospital is mainly characterized by carbapenem-resistantEnterobacteriaceae, multiple drug resistant A. baumanniiand multiple drug resistantP. aeruginosa. Surveillance of antimicrobial resistance is beneifcial for rational use of antibiotics.

Objective: To compare the effects of modified Thrombolysis in Cerebral Infarction score (mTICI) 2b and mTICI 3 reperfusion on lesions′ changes and prognosis in patients who underwent endovascular therapy within six hours after onset. Methods: A retrospective analysis was conducted on 94 patients with acute large intracranial artery occlusion of the anterior circulation who achieved reperfusion sucesssfully by endovascular therapy within 6 hours after onset in the Department of Neurology, Nanjing First Hospital from October 2016 to March 2019. The effects of mTICI 2b and mTICI 3 reperfusion on lesions′ changes and prognosis of patients were compared. The primary endpoint was the modified Rankin Scale (mRS) score at 90 days; the secondary endpoints were the early neurological deficit score, the mortality at 90 days, the volume of infarction at 24 hours, the changes in infarct volume for 24 hours and the rate of symptomatic intracerebral hemorrhage (sICH) , reocclusion and hemorrhagic transformation. Results: In all patients, 35 cases received mTICI 2b reperfusion and 59 cases received mTICI 3 reperfusion. Compared with mTICI 2b group (10.00 (3.00, 16.00)), the early neurological deficit score at seven days of mTICI 3 group (6.00 (1.00,11.50)) was lower (Z=-2.004, P=0.045) . However, there were no statistically significant differences in mRS score at 90 days, early neurological deficit score at 24 hours and 3 days, mortality at 90 days, volume of infarction at 24 hours, the changes in infarct volume for 24 hours, and the rate of sICH, reocclusion, and hemorrhagic transformation between the two groups. Conclusion For patients with large intracranial artery occlusion of the anterior circulation within six hours after onset, achieving mTICI 3 reperfusion after endovascular therapy can improve the early neurological function more effectively, but the effects on 90-day functional outcome are similar to that of mTICI 2b reperfusion.

Objective:To investigate the efficacy and safety of traditional laser photocoagulation, laser combined with intravitreal injection of anti-vascular endothelial factor (anti-VEGF) drugs and intravitreal injection of anti-VEGF drugs alone in Coats disease.Methods:The patients diagnosed as Coats disease stage 2B-3A2 in Department of Ophthalmology, Eye and ENT Hospital of Shanghai Medical College of Fudan University from December 2016 to November 2019 were included in this study. Patients were divided into three groups, including laser group, combined group and drug group, according to the different treatment. In the laser group, the initial treatment was traditional laser photocoagulation alone. In the drug group, the anti-VEGF drug was injected into vitreous once a month for three months. The initial treatment of the eyes in the combined group was laser combined with intravitreal injection of anti-VEGF drugs, or laser treatment within 1 week after anti-VEGF drug treatment. The follow-up time was more than 6 months, and best-corrected visual acuity (BCVA), ultra-wide-angle fundus photography, and fluorescein fundus angiography were performed during follow-up. The treatment efficiency, subretinal fluid (SRF), macular edema, BCVA and complications were compared among the three groups.Results:Among 60 patients (60 eyes), there were 55 males (55 eyes) and 5 females (5 eyes), with the mean age of 17.1±2.0 years. Among 60 eyes, there were 26 eyes in 2B stage, 23 eyes in 3A1 stage, and 11 eyes in 3A2 stage. Twenty patients (20 eyes) was in the laser group, combined group and drug group, respectively. After the initial treatment of all eyes in the drug group, the abnormal blood vessels did not regress significantly; the absorption and increase of SRF were 4 (20.0%, 4/20) and 5 (25.0%, 5/20) eyes, respectively. Supplementary laser therapy was given to 16 eyes, and vitrectomy (PPV) was given to 4 eyes. Among the 16 eyes treated by laser, 10 eyes were effective (50.0%, 10/20); vitreous hemorrhage, fibrous membrane hyperplasia, and complicated cataract occurred in 1, 1, and 2 eyes during the treatment, respectively, and PPV was given again in all eyes. Recurrent and persistent macular edema occurred in 4 and 1 eyes, respectively. Among the eyes in the combined group, treatment were effective in 11 eyes (55.0%, 11/20); 5, 2, and 2 eyes had SRF, fibrous membrane hyperplasia, and complicated cataract during the treatment, and PPV was given again; the edema was repeated and persisted in 1 eye, respectively. Among the affected eyes in the laser group, 15 eyes (75.0%, 15/20) were treated effectively; 2, 2, and 1 eyes developed a large number of vitreous hemorrhage, fibrous membrane hyperplasia, and complicated cataract during the treatment, and PPV was given again.Conclusions:Anti-VEGF drugs alone are ineffective in the treatment of Coats disease, and ablation of other abnormal blood vessels is needed. In the treatment of Coats disease, anti-VEGF drugs can not only promote the absorption of SRF, but also may lead to its increase, and the application should be cautious.

Objective:To investigate macular microvascular abnormalities in eyes with subfoveal fibrotic nodules secondary to Coats' disease.Methods:A cross-sectional study. From January 1, 2018 to July 30, 2021, 45 eyes of 45 patients diagnosed with Coats' disease with or without subfoveal fibrotic nodules in Eye and ENT Hospital, Shanghai Medical College of Fudan University were included in this study. There were 40 eyes in 40 males and 5 eyes in 5 females. All were under 21 years old. According to the presence or absence of subfoveal fiber nodules, the patients were divided into fibrotic group (26 cases, 26 eyes) and non-fibrotic group (19 cases, 19 eyes). Optical coherence tomography angiography was used to scan 3 mm×3 mm or 6 mm×6 mm macular area of both eyes. The software of the device automatically processed the images. The presence of FAZ edge anastomotic vascular arch ring breakage and abnormal microvascular branch (AMB) in the foveal avascular zone (FAZ) were observed.Results:In 26 eyes of fibrosis group, AMB originating from the parafoveal retinal capillary network was observed, which grew into and destroyed the integrity of the vascular arch ring at the edge of FAZ. AMB was crisscrossing and winding, and its curvature expands. B-scan images showed the blood flow signal in the subfoveal fiber nodule, and the blood flow signal traversed between the inner retina and the fiber nodule in 23 eyes (88.46%, 23/26). In the non-fibrosis group, all the vascular abnormalities were characterized by capillary dilation and defect, and no breakage of FAZ anastomotic vascular arch ring or AMB was observed.Conclusions:In Coats' disease with subfoveal fiber nodules, staggered and dilated AMBs emerge from the parafoveal vascular network, grow into and destroy the integrity of the vascular arch ring at the edge of FAZ, and grow down longitudinally into the fiber nodules.

Objective:To investigate the longitudinal trajectory and influencing factors of cancer-related fatigue (CRF) in breast cancer patients during chemotherapy.Methods:From March 2019 to January 2020, breast cancer patients in Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Yueyang Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Shanghai University of Traditional Chinese Medicine and Peking Union Medical College Hospital were selected as the research objects to conduct follow-up investigation. The survey tools included general information questionnaire, Cancer-related Fatigue Assessment Scale, International Physical Activity Questionnaire, and the Pittsburgh Sleep Quality Index Scale.Results:A total of 91 patients were included in the study. The incidence of severe CRF at each time point before chemotherapy, 3 weeks after chemotherapy and 6 weeks after chemotherapy were 1.1% (1/91), 8.8% (5/57) and 2.1% (1/48), respectively. The results of the generalized estimation equation showed that the trajectory of the total score CRF firstly increased and then decreased, reaching a peak at 3 weeks after chemotherapy (35.45±13.07), and mild CRF change showed statistical difference ( P<0.05). In addition, BMI and sleep and daytime dysfunction were the influencing factors of the total score of CRF. Disease stage, sleep disturbance and daytime dysfunction were the influencing factors of CRF with different severity. Conclusions:CRF is a prominent problem in breast cancer patients during chemotherapy. Attention should be paid to high-risk individuals with abnormal BMI and daytime function by medical staff.

Under the national policy background of traditional Chinese medicine（TCM）registration review and approval reform， TCM preparations in medical institutions（hereinafter referred to as medical institution preparations） have human use experience， conform to the characteristics of TCM clinical practice， and have advantages in the research and development of innovative Chinese medicines. Therefore， the research and development mode based on clinical experience prescription-medical institution preparations-innovative Chinese medicines has attracted widespread attention from the industry. However， in the process of development and use of medical institution preparations， there are generally clinical problems that restrict their transformation into innovative Chinese medicines， resulting in a relatively weak collection basis of human use experience and insufficient clinical evidence for supporting the research and development of new TCM medicines. In this paper， on the basis of sorting out the supporting regulations and relevant technical requirements of human use experience， and analyzing the clinical problems restricting the transformation of medical institution preparations， it provides suggestions for medical institutions to carry out high-quality research on human use experience of preparations in the process of TCM clinical practice from the aspects of continuously exploring clinical value， improving the construction of information system， focusing on the TCM clinical practice and giving full play to the advantages of discipline cooperation. By realizing the whole life cycle management of medical institution preparations based on three-combination evaluation evidence system， we can promote the transformation of medical institution preparations into innovative Chinese medicines.
