Objective To screen monoclonal antibodies (mAbs) for early diagnosis of invisive Aspergillus. Methods Monoclonal antibodies against different antigens of Aspergillus fumigatus were produced. The two pairs of combinations of monoclonal antibodies were selected accoring the distinct epitopes and double-antibody sandwich ELISA based on mAbs above were established. The sensitivity and specificity of the methods were analyzed by detecting culture supernatants of clinical isolates and environmental isolatesof Aspergillus. spp, Penicillium Marneffei, Candidas, and serum from animal models and patients. The epitopes recognized by mAbs were identified by immunobotting. Results A total of 32 hybridoma cell lines that stably produced MAbs were obtained. Two double- antibody sandwich ELISAs were established. One method was specific for 19 clinical isolates and environmental isolates of Aspergillus. spp, whereas the other one was specific for the clinical and environmental isolates of Aspergillus fumigatus without cross-reation with other Aspergillus. spp. For the same kind of medium of Aspergillus fumigatus, the sensitivity of the first method was 10 fold higher than the second method. Conclusions The specific mAbs for early diagnosis of invisive Aspergillus were obtained. Antigen recognized by the specific mAbs was mannoprotein with molecular weights of approximately 25 000-75 000. This antigen was potential early diagnostic marker for invasive Aspergillus.

Objective To improve the quality of the management of the elderly patients with cancer in Sichuan province,and to understand the attitudes and perspectives of elderly surgeons and oncologists for the management and treatment of elderly patients with cancer.Methods A face-toface questionnaire interview was conducted with oncologists (n 64) and geriatricians (n =64).128 physicians were involved in this study.Results The cancer management and therapeutics were deemed appropriate at present by 9.38％ (6/64)of the geriatricians and 25.00％ (16/64)of the oncologists.The 39.06％ (25/64) of geriatricians used to notice geriatric syndromes,while 81.25％ (52/64)of oncologists never concerned about the geriatric syndrome(P=0.011).As for the causes of the therapy-associated toxicity,oncologist versus geriatrician payed an attention to malnutrition (100.00％ vs.100.00％ in both groups),to mobility disorders(65.63％ vs.65.63％,84/128 in both groups),to cognitive impairment/mood disorder (89.06％ in geriatrician group vs.75.00％ in oncologist group,P=0.038).For the factors affecting treatment decisions,a physical ability attention (oncologists vs geriatricians:70.31％ vs.92.19％;P =0.002),and comorbidity (oncologists vs geriatricians:62.50％ vs.79.69％,P =0.032) had statistically significant difference.In addition,lack of geriatrics knowledge was also reported by more oncologists.However,one hundred percent of participants wanted very much to cooperate with each other in their clinical work.When responding to the clinical scenario,the 10.94％ (7/64)of geriatricians and 32.81％ (21/64)of oncologists chose modified treatment for 65-74 years old patient with cancer(P =0.003).When the age of the patients was 75-84 years old,only 12.50 ％ (8/64) of geriatricians prefer end-of-life care,while 31.25 ％ (20/64) of oncologists chose it (P =0.010).Conclusions Selection of treatment decisions in the elderly patients with cancer affect by ageing.Both oncologists and geriatricians are concerned with the elderly patients with cancer,ageing syndrome,total sickness and functional status.And these doctors support an establishment of a multi disciplinary team cooperation for the elderly patients with cancer.Therefore,the establishment of mutual cooperation between the two professionals is necessary and feasible.

Objective: To investigate the clinical outcomes of arthroscopic bridging reconstruction of irreparable massive rotator cuff tears using autogenous fascia lata. Methods: From July 2015 to July 2017, a total of 10 cases (4 male and 6 female) who were treated with arthroscopic bridging reconstruction for irreparable massive rotator cuff tears using autogenous fascia lata were retrospectively analyzed. The age before surgery was 61.3±2.9 years (range 57-67 years). There were 7 patients with right shoulders and 3 with left shoulders. The dominate sides were involved in 7 cases. The trauma history was documented in 2 shoulders. The duration of preoperative symptoms was 14.0±13.5 months (1-48 months). The case with revision surgery was not included. The patients were examined with magnetic resonance imaging (MRI) to evaluate the healing of fascia lata patch bridging in the joint at one week, six months, one year and two years after operation. The motion range of shoulder and the clinical scores, including visual analogue scale (VAS), University of California Los Angeles (UCLA) score, Constant-Murley score and American Shoulder & Elbow Surgeons (ASES) score, were measured before surgery and at follow-up duration. Results: All cases were reconstructed the horizontal couple. No perioperative complication was occurred and all surgery were completed safely and successfully. At the end of two years, the score of ASES was 92.2±3.5 (range 88.3-98.3), UCLA 31.6±2.0 (range 28-34), Constant-Murley 85.2±5.4 (range 78-93) with significant difference (t=11.254, P=0.000; t=12.111, P=0.000; t=8.948, P=0.00) comparing with that before surgery. The VAS pain score was 0.6±0.5 (range 0-1) which was significantly lower than that preoperatively (t=11.326, P=0.000). At 2 years after operation, MRI shows that fascia lata patches healed well in 9 patients. However, one case was with re-tear and patch absorption. The range of motion of shoulder was significantly improved in all patients but with different degrees of weakness (3-4). Conclusion Arthroscopic bridging reconstruction using autogenous fascia lata could effectively improve shoulder function in patients with irreparable massive rotator cuff tears. The autogenous fascia lata patch can heal with the help of rotator cuff tissue through bridging reconstruction.

OBJECTIVES: At present, hysteroscopic submucosal fibroids resection is mostly performed by hysteroscopic electric resection (hereinafter referred to as electric knife). During the operation, the electrothermal effect could not only damage the endometrial tissues covered by the surface of the fibroid, but also easily damage the endometrial tissues around the fibroid, which is very unfavorable for patients with fertility requirements. In addition, for some special fibroids (located at horn and fundus) or Type II and multiple submucosal fibroids, the traditional electric resection is still very difficult. With the opening of the second-child policy and the urgent desire of patients for fertility, more and more attention is paid to the concept of fertility protection in China. Therefore, hysteroscopic cold knife technology (hereinafter referred to as cold knife) has gradually entered the vision. The cold knife has the advantages of simple operation, such as little trauma and quick postoperative recovery. In this study, the advantages of cold knife in the surgical resection of submucosal fibroids are discussed by comparing the safety and effectiveness between the hysteroscopic cold knife resection (hereinafter referred to as cold knife) and the electric knife resection in the submucosal fibroids. METHODS: The clinical data of 112 patients with submucosal fibroids diagnosed and treated by hysteroscopic surgery at the Third Xiangya Hospital of Central South University from January 2017 to October 2021 were retrospectively analyzed, including preoperative general information (such as age, gravidity, abortion times, the size, location, type and number of submucosal fibroids, preoperative hemoglobin value) and intraoperative conditions [such as intraoperative bleeding, the operation time, residual rates and intraoperative complications (massive bleeding, perforation, water poisoning)]. The patients were divided into a cold knife group and an electric knife group, and there were 40 cases in the cold knife group and 72 cases in the electric knife group. The postoperative complications and the pregnancy outcomes in the 2 groups were followed up by telephone, the follow-up data included postoperative recurrence rate, pregnancy rate, pregnancy mode, and pregnancy outcome. RESULTS: Compared with the electric knife group, the cold knife group had more submucous myomas located in the horn or fundus of the uterus (9.7% vs 25.0%), and more Type II myomas or combined with Type II myomas (26.4% vs 70.0%). However, there were no significant difference in intraoperative bleeding, the operation time, intraoperative complications and the residual rates between the 2 groups (all P>0.05). A total of 98 patients were followed up, including 32 patients in the cold knife group and 66 patients in the electric knife group. Compared with the electric knife group, there were lower postoperative complications in the cold knife group (12.5% vs 37.9%) (P<0.05). Among the 7 patients with multiple submucosal fibroids (the number of fibroids ≥5), there were 4 patients in the electric knife group and 3 patients in the cold knife group. In the electric knife group, the postoperative menstrual volume in the 4 patients was significantly reduced and 3 patients had postoperative fertility requirements, which were all diagnosed as intrauterine adhesion by hysteroscopy and performed further surgery. Later, 2 patients had successful pregnancy, 1 had miscarriage, and 1 had full-term spontaneous labor. However, the menstrual volume of the 3 patients in the cold knife group was not significantly reduced compared with normal menstrual volume, and 2 of them had fertility requirements, and they had natural pregnancy and full term vaginal delivery. There were no significant differences in postoperative recurrence rate, pregnancy rate, pregnancy mode and pregnancy outcome between the 2 groups (all P>0.05). CONCLUSIONS Both the electric knife and cold knife resection are safe and effective methods for the treatment of submucosal fibroids. Compared with electric knife resection, the cold knife resection has fewer postoperative complications and perhaps more advantages in endometrial protection, especially for the patients with fertility requirements, submucosal fibroids located at the fundus or horn of the uterus, Type II submucosal fibroids, and multiple submucosal fibroids.

【Objective】 To investigate the effects of one-stage additional posterior pedicle screws （PPS） internal fixation on early Cage subsidence after oblique lateral interbody fusion （OLIF）. 【Methods】 We made a retrospective analysis of 118 patients with lumbar degenerative diseases treated with OLIF at the Department of Orthopedics， Sir Run Run Shaw Hospital， School of Medicine， Zhejiang University， from January 2016 to December 2019. We divided the patients into OLIF stand-alone group （58 ones） and OLIF with PPS fixation group （60 ones） according to the surgical procedure. All the patients had preoperative frontal and lateral radiographs of the lumbar spine， and CT and MR scans were performed. The clinical outcomes and reoperation rates of the two groups were compared at immediate postoperative follow-up and at 1， 3， 6 and 12 months. X-ray and CT examinations were performed to assess Cage subsidence in both groups at each postoperative follow-up. 【Results】 There was no statistical difference between the two groups in baseline data and surgical segmentation. Of the 118 patients with 141 discs who underwent OLIF surgery， 58 patients with 68 discs received OLIF stand-alone surgery and 60 ones with 73 discs received OLIF with PPS fixation. There were no significant differences in intraoperative bleeding， complications， or postoperative clinical outcomes between the two groups （P>0.05）， and the Cage subsidence rate was 22.4% in OLIF stand-alone group and 5% in OLIF with PPS fixation group， with significant difference between the two groups （P<0.01）. 【Conclusion】 Both OLIF stand-alone and OLIF additional PPS fixation can achieve good early clinical outcomes， and first-stage additional PPS fixation can significantly reduce the occurrence of Cage subsidence in the early postoperative period after OLIF.
