ABSTRACT
Objective:To explore the outcome of sponge forceps assisted threading with Speedbridge technique for the treatment of acute closed Achilles tendon rupture.Methods:A retrospective case series study was conducted on 20 patients with acute closed Achilles tendon rupture treated in Zhengzhou Orthopedic Hospital from December 2019 to December 2021. There were 18 males and 2 females, with age range of 24-43 years [(29.5±7.6)years]. All patients were with unilateral injury, involving the left side in 13 patients and right side in 7. Examinations revealed a palpable defect in the Achilles tendon and positive Thompson test. A longitudinal incision was made at the medial edge of the ruptured tendon. Three nonabsorbable sutures were passed through the proximal stump with sponge forceps, bypassed the rupture site and fixed directly into the calcaneal bone. The disrupted tendon ends were aligned by the tendon-bundle technique using 4-0 absorbable sutures. The operation time and incision length were documented. The ankle joint range of motion (dorsiflexion/plantar flexion), American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Achilles tendon total rupture score (ATRS) in the affected and healthy side were compared at 3, 6 and 12 months postoperatively. The wound healing and complications were observed.Results:All patients were followed up for 12-16 months [(13.2±2.5)months]. The operation time was 40-66 minutes [(52.0±10.3)minutes], with the incision length of 3-4 cm [(3.3±0.7)cm]. In the affected side at 3 and 6 months postoperatively, the ankle joint dorsiflexion [(5.6±1.5)°, (10.5±0.2)°] and plantar flexion [(28.4±3.2)°, (33.5±1.5)°] showed statistically significant difference compared with the healthy side (all P<0.05). The ankle joint dorsiflexion [(13.9±0.7)°] and plantar flexion [(38.3±4.4)°] in the affected side were not statistically different from that of the healthy side at 12 months postoperatively (all P>0.05). The AOFAS ankle-hindfoot score was (58.3±5.4)points, (84.9±7.1)points and (91.8±6.3)points at 3, 6 and 12 months postoperatively, showing a gradual rise (all P<0.05). The ATRS was (60.5±4.9)points, (85.5±9.0)points and (93.1±5.7)points at 3, 6 and 12 months postoperatively, showing a gradual rise (all P<0.05). All incisions were healed primarily. No patients had wound infection, nerve injury or re-rupture. Pain at the anchor insertion site occurred in 2 patients at 1 month after operation and relieved after active functional rehabilitation at 4 months after operation. Transient pain at the Achilles tendon insertion occurred in 1 patient at 6 months after operation, and relieved after 2 weeks of oral non-steroidal anti-inflammatory drugs treatment. Conclusion:For acute closed Achilles tendon rupture, sponge forceps assisted threading with Speedbridge technique can attain short operation time, small incision and good functional recovery, with few complications.

The average daily radiotherapy patients in county-level or below, city-level, and provincial-level institutions were 25.78, 65.68, and 173.76, respectively, and the per capita workload index was 5.22, 8.09, and 10.11.Conclusions:Compared with the 2019 survey, the educational background of radiotherapists in mainland China has been improved, and the title structure has been optimized to a certain extent, and the workload of large-scale radiotherapy units is larger than that of grass-roots units.
ABSTRACT
Objective:To summarize the clinical experience of extracorporeal membrane oxygenation (ECMO) for neonatal refractory respiratory failure in a single medical center of Southwest China.Methods:From June 2020 to November 2021, the clinical data of neonates with refractory respiratory failure who received ECMO in the neonatal department of our hospital were retrospectively reviewed. The neonates were assigned into the survival group and the deceased group.Their general profile, clinical diagnosis, laboratory tests, ECMO operation, complications and prognosis were compared.Results:Eight neonates were included with five successfully withdrawal of ECMO and survived (5/8). For the three deceased neonates, two discontinued treatment because of intraventricular hemorrhage (grade Ⅲ~Ⅳ) and one confirmed congenital adrenal hyperplasia. No significant differences existed between the survival and the deceased groups in oxygenation index (OI), ECMO preparation and operation duration, usage of heparin, red blood cell suspension, platelet and sedative/analgesic drugs, therapeutic hypothermia and ECMO-associated complications. However, the deceased group had high OI values ( P=0.001), low lactate clearance ( P=0.005), more urine output during the first 24 h after ECMO ( P=0.046) and more fresh frozen plasma usage ( P=0.038). None of the five surviving children had significant developmental delay and neurological abnormalities during the 1-year follow-up. Conclusions:ECMO is effective treating neonatal refractory respiratory failure. Reducing the risk of intraventricular hemorrhage during ECMO may improve the survival rate.
ABSTRACT
Teratoma is a rare tumor, mainly occurring in the ovary, sacrococcygeal region, testis, central nervous system and mediastinum, rarely occurring in the kidney, and adult immature teratoma originating in the kidney is extremely rare. A case of adult left renal immature teratoma was reported in this paper. After radical nephrectomy, pathological examination found that the tumor tissue contains malignant epithelial tissue and a small number of brain tissue. BEP regimen chemotherapy was performed after operation.The patient was followed up for 26 months, and died of organ failure caused by systemic metastasis.
ABSTRACT
Objective:To investigate and analyze the basic occupational situation of Chinese radiotherapists and to provide references for the development and construction of the radiation therapist team in China.Methods:Between May 7, 2021 and June 15, 2021, this survey was conducted using a self-designed questionnaire, which was distributed and collected in the form of online survey to conduct a statistical analysis of the basic situation of radiotherapists in 30 provincial-level administrative regions in China.Results:A total of 2 928 valid questionnaires were collected from 30 provincial-level administrative regions. The ratio of male to female and average age of the participants were 69∶31 and 35 years (18-65), respectively. According to the survey result, 84.7% of the participants came from Tertiary A-level hospitals. In terms of educational background, the participants with doctoral, master, undergraduate, junior-college, and technical-secondary degrees accounted for 0.2%, 6.9%, 76.6%, 14.9%, and 1.4%, respectively. In terms of title, full senior technologists, associate senior technologist, technologist-in-charge, technologist, and technician in the participants accounted for 0.5%, 5.8%, 32.5%, 52.2%, and 8.2%, respectively. The participants with years of employment of 0-, 5-, 10-, 20-y accounted for 33.74%, 25.79%, 25.51%, and 14.96%, respectively. The majors of the participants included medical imaging/imaging technology (45.9%), clinical medicine (19.1%), and biomedical engineering (11.9%).Conclusions:Chinese radiotherapists tend to be younger and are rapidly increasing in number. Employers should attach importance to the career planningand continuing education of radiotherapists to improve their technical skills, in order to fully satisfy the demand for radiotherapists in the new era.
ABSTRACT
Clinical and endoscopic data of 6 patients with colorectal mucosa associated lymphoid tissue (MALT) lymphoma who were diagnosed by endoscopy in the Digestive Endoscopy Center of Jiangsu Province Hospital of Chinese Medicine from January 2015 to June 2021 were retrospectively analyzed. There were 2 males and 4 females with aged from 62 to 87 years. The lesions were located in rectum in 3 cases, transverse colon in 1 case, sigmoid colon in 1 case, and sigmoid colon and rectum in 1 case. There were 1 case of polyposis type, 2 cases of inflammation type, and 3 cases of submucosal tumor type. The "tree-like appearance (TLA)" found in 5 cases. Endoscopic resection, surgery combined with chemotherapy, Helicobacter pylori eradication and follow-up were performed on 2, 1, 1 and 2 cases, respectively. Five cases had a good prognosis after 21-73 months follow-up, and 1 case had lost to follow-up. No recurrence was found in endoscopic and imaging review. Colorectal MALT lymphoma should be considered when colonoscopy detects a submucosal lesion with TLA sign on the left colon. Endoscopic resection has the potential to be a first-line treatment in the context of early diagnosis.
ABSTRACT
Objective@#: Extracranial supra-aortic dissections (ESADs) with severe stenosis, occlusion and/or pseudoaneurysm presents potential risk of stroke. Endovascular stenting to reconstruct non acute phase ESADs (NAP-ESADs) is an alternative to anticoagulant or antiplatelet therapy. However, its feasibility, safety and efficacy of stenting in NAP-ESADs is unclear. This study aims to investigate the long-term outcomes of the feasibility, safety and efficacy of stenting in NAP-ESADs. @*Methods@#: Seventy-four patients with 91 NAP-ESAD vessels with severe stenosis, occlusion and/or pseudoaneurysm presents potential risk of stroke who underwent stent remodeling were enrolled into this respective study from December 2008 to March 2020. Technical success rate, complications, clinical and angiographic results were harvested and analyzed. @*Results@#: Success rate of stent deployment was 99% (90/91) with no procedural mortality or morbidity. Transient ischemic attack occurred in three patients during operation (4.1%, 3/74). Asymptomatic embolisms of distal intracranial vessels were found in two patients (2.7%, 2/74). One hundred and forty-two stents deployed at 85 carotid (135 stents) and six vertebral (seven stents) vessels. Six stent types (Wingspan, 28/135, 20.7%; Solitaire, 10/135, 7.4%; Neuroform, 8/135, 5.9%; LVIS, 2/135, 1.5%; Precise, 75/135, 55.6%; Acculink, 12/135, 8.9%) were deployed at carotid arterial dissection while two types (Wingspan, 5/7, 71.4%; Solitaire 2/7, 28.6%) at vertebral arterial dissection. Digital subtracted angiography (56%, 51/91), computational tomography angiography (41.8%, 38/91) and high resolution magnetic resonance imaging (2.2%, 2/91) were adopted for follow up, with a mean time of 17.2±15.4 months (5–77). All patient modified Rankin Scale scores showed no increase at discharge or follow-up. Angiographically, dissections in 86 vessels in 69 patients (94.5%, 86/91) were completely reconstructed with only minor remnant dissections in four vessels in four patients (4.4%, 4/91). Severe re-stenosis in the stented segment required re-stenting in one patient (1.1%, 1/91). @*Conclusion@#: Stent remodeling technique provides feasible, safe and efficacious treatment of ESADs patients with severe stenosis, occlusion and/or pseudoaneurysm.
ABSTRACT
@#Objective To analyze the operation outcomes and learning curve of uniportal video-assisted thoracoscopic surgery (VATS). Methods All consecutive patients who underwent uniportal VATS between November 2018 and December 2020 in Shangjin Branch of West China Hospital of Sichuan University were retrospectively enrolled, including 62 males and 86 females with a mean age of 50.1±13.4 years. Operations included lobectomy, segmentectomy, wedge resection, mediastinal mass resection and hemopneumothorax. Accordingly, patients' clinical features in different phases were collected and compared to determine the outcome difference and learning curve for uniportal VATS. Results Median postoperative hospital stay was 5 days, and the overall complication rate was 8.1% (12/148). There was no 30-day death after surgery or readmissions. Median postoperative pain score was 3. Over time, the operation time, incision length and blood loss were optimized in the uniportal VATS lobectomy, the incision length and blood loss increased in the uniportal VATS segmentectomy, and the postoperative hospital stay decreased in the uniportal VATS wedge resection. Conclusion Uniportal VATS is safe and feasible for both standard and complex pulmonary resections. While, no remarkable learning curve for uniportal VATS lobectomy is observed for experienced surgeon.
ABSTRACT
The clinical characteristics, laboratory tests, treatment and prognostic characteristics of a case of neurexin-3α antibody-mediated autoimmune encephalitis,who was admitted in Xi′an International Medical Center Hospital on January 4, 2020 were summaried. The patient was a 56-year-old male with pre-symptoms of infection before his illness. The main manifestations were rapid progress of cognitive dysfunction, mental and behavioral abnormalities, refractory epilepsy, and status epilepticus, dystonia, accompanied by autonomic nerve involvement such as increased heart rate, breathing, and sweating, suspected of central hypoventilation, clinical manifestations were similar to N-methyl-D-aspartate-receptor (NMDAR) encephalitis and magnetic resonance imaging suggested bilateral hippocampal, temporal, and insular high signals, cerebrospinal fluid examination and other laboratory tests were normal. After treatment with methylprednisolone and intravenous immunogloblin, he died a few days after being discharged. The clinical manifestations of neurexin-3α antibody-mediated autoimmune encephalitis were similar to NMDAR encephalitis and severe, and neurexin-3α antibodies need to be further tested to confirm the diagnosis when NMDAR antibody was negative.
ABSTRACT
Objective@#: This study aims to investigate the relationship between aneurysm wall enhancement and clinical rupture risks based on the magnetic resonance vessel wall imaging (MR-VWI) quantitative methods. @*Methods@#: One hundred and eight patients with 127 unruptured aneurysms were prospectively enrolled from Feburary 2016 to October 2017. Aneurysms were divided into high risk (≥10) and intermediate-low risk group (<10) according to the PHASES (Population, Hypertension, Age, Size of aneurysm, Earlier SAH history from another aneurysm, Site of aneurysm) scores. Clinical risk factors, aneurysm morphology, and wall enhancement index (WEI) calculated using 3D MR-VWI were analyzed and compared. @*Results@#: In comparison of high-risk and intermediated-low risk groups, univariate analysis showed that neck width (4.5±3.3 mm vs. 3.4±1.7 mm, p=0.002), the presence of wall enhancement (100.0% vs. 62.9%, p<0.001), and WEI (1.6±0.6 vs. 0.8±0.8, p<0.001) were significantly associated with high rupture risk. Multivariate regression analysis revealed that WEI was the most important factor in predicting high rupture risk (odds ratio, 2.6; 95% confidence interval, 1.4–4.9; p=0.002). The receiver operating characteristic (ROC) curve analysis can efficiently differentiate higher risk aneurysms (area under the curve, 0.780; p<0.001) which have a reliable WEI cutoff value (1.04; sensitivity, 0.833; specificity, 0.67) predictive of high rupture risk. @*Conclusion@#: Aneurysms with higher rupture risk based on PHASES score demonstrate increased neck width, wall enhancement, and the enhancement intensity. Higher WEI in unruptured aneurysms has a predictive value for increased rupture risk.
ABSTRACT
@#Objective To investigate the efficacy of uniportal video-assisted thoracoscopic surgery (VATS) anatomic basal segmentectomy. Methods The clinical data of 15 patients who underwent uniportal VATS anatomic basal segmentectomy between June 2020 and December 2020 were retrospectively reviewed. There were 4 males and 11 females with a median age of 53 (32-70) years. The incisions were placed in the fifth intercostal space across the mid-axillary line. All basal segmentectomies were performed through the interlobar fissure or inferior pulmonary ligament approach following the strategies of single-direction and stem-branch. Results All patients underwent basal segmentectomy successfully with no conversion to multi-portal procedure or thoracotomy. The median operation time was 120 (90-160) min, median intraoperative blood loss was 20 (10-50) mL, median drainage time was 3 (2-5) d, and median postoperative hospital stay was 4 (4-10) d. The maximum diameter of the lesion in the resected basal segment was 1.2 (0.7-1.9) cm. The median resected lymph nodes were 7 (5-12). There was no evidence of nodal metastases. One patient suffered postoperative atelectasis and subsequent pneumonia. No perioperative death occurred. Conclusion Uniportal VATS anatomic basal segmentectomy is feasible and safe. It can be performed in a simple manner following the strategy of single-direction.
ABSTRACT
Objective:To analyze the therapeutic effect of ankle arthrodesis with reverse proximal humerus internal locking system plating plus cannulated screwing via the transfibular approach in the treatment of end-stage ankle arthrosis.Methods:From April 2014 to January 2018, 19 patients (19 ankles) with end-stage ankle osteoarthritis were treated at Department of Foot and Ankle Surgery, Zhengzhou Orthopaedics Hospital by ankle arthrodesis with reverse PHILOS plating plus cannulated screwing via the transfibular approach for multi-plane fixation. They were 9 men and 10 women, aged from 36 to 65 years (average, 46.7 years). The disorder was further diagnosed as traumatic arthritis in 9 cases, as osteoarthritis in 6, as talar necrosis in 2 and as equinovarus in 2, and affected the left ankle in 11 cases and the right in 8. All cases belonged to stage Ⅲ osteoarthritis according to the Morrey-Wiedeman imaging classification. Their American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS), joint fusion and complications were observed preoperatively and at the last follow-up.Results:All the 19 patients were followed up for 18 to 62 months (average, 31.5 months). Their AOFAS scores were improved from preoperative 46.3±2.1 to 81.6±0.9 at the last follow-up, and their VAS was reduced from preoperative 7.1±0.2 to 2.0±0.2 at the last follow-up, showing significant differences ( P<0.001). All their ankle joints obtained bony fusion after 9 to 14 weeks (mean, 11.5 weeks). No implant loosening or breakage was observed. All the patients were satisfied with their operative results at the last follow-up. Dorsal lateral foot numbness was observed in one patient who became asymptomatic after neurotrophic medication for 3 months. Lateral distal wound dehiscence happened during removal of stitches at 2 weeks after operation in another patient but healed after debridement. The last follow-up found subtalar joint degeneration in 2 cases and talonavicular joint degeneration in one but no clinical symptoms in the 3. Conclusion:Ankle arthrodesis with reverse PHILOS plating plus cannulated screwing via the transfibular approach is a fine treatment for end-stage ankle arthrosis, because it leads to reliable fixation, short fusion time, alleviated pain and improved ankle function.

ABSTRACT
Space-occupying brain edema is a life-threatening complication in patients with cerebellar infarction, which occurs in 17-54% of the patients. The level of consciousness should be monitored closely and the changes of CT/MRI should be followed up for cerebellar infarction patients with a higher risk of deterioration. Ventriculostomy/extraventricular drainage and suboccipital decompressive craniectomy should be performed in space-occupying cerebellar infarction patients with clinical deterioration.
ABSTRACT
Numerical simulation of stent deployment is very important to the surgical planning and risk assess of the interventional treatment for the cardio-cerebrovascular diseases. Our group developed a framework to deploy the braided stent and the stent graft virtually by finite element simulation. By using the framework, the whole process of the deployment of the flow diverter to treat a cerebral aneurysm was simulated, and the deformation of the parent artery and the distributions of the stress in the parent artery wall were investigated. The results provided some information to improve the intervention of cerebral aneurysm and optimize the design of the flow diverter. Furthermore, the whole process of the deployment of the stent graft to treat an aortic dissection was simulated, and the distributions of the stress in the aortic wall were investigated when the different oversize ratio of the stent graft was selected. The simulation results proved that the maximum stress located at the position where the bare metal ring touched the artery wall. The results also can be applied to improve the intervention of the aortic dissection and the design of the stent graft.

After operation, complications in clued pelvic hemorrhage in 1 case and ureteral fistula in 1 case, all improved after conservative treatment.According to pathological and immunohistochemical results, 7 cases were MSFT and 5 cases were SFT. All patients were followed up for 2-53 months. 5 cases were recurrent, among which 1 case died of intestinal obstruction caused by tumor compression.Conclusion:The clinical manifestations of solitary fibrous tumors are mostly nonspecific.Imaging examination and puncture pathology are of great significance for preoperative diagnosis. Radical resection is an important means to improve the prognosis of patients.
ABSTRACT
Objective:To evaluate the clinicopathological features of primary retroperitoneal paragangliomas.Methods:Data of 24 patients with retroperitoneal paragangliomas who underwent surgical treatment in our hospital from Jan 2015 to Dec 2018 was collected and analyzed.Results:Hypertension, abdominal pain/discomfort and headache were the most common complaints while 10 patients were asymptomatic and were diagnosed accidently in routine body examination. Tumor size ranged from 3.4-13.0 cm (6.9±2.5) cm, and all the tumors were located in the vicinity of abdominal aorta and inferior vena cava. All the patients received surgical treatment. Intraoperative blood pressure fluctuations were significantly correlated with prolonged operation time, more blood loss, more blood transfusion and prolonged length of stay (all P<0.05). The median follow-up time was 29 months and 1 patient died from tumor recurrence and progression. The other patients have had a tumor free survival. Conclusions:Surgical resection was the principal treatment of primary paraganglioma. Preoperative assessment was very important for perioperative safety.

ABSTRACT
Congenital heart disease (CHD) is the most common congenital malformation and also one of the common causes of heart failure in children.At present,the clinical diagnosis of heart failure in children mainly depends on the medical history,symptoms and signs,with strong subjectivity and lack of timely and simple objective criteria,which are easy to be missed.Brain natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-ProBNP) are polypeptides synthesized and secreted by ventricular myocytes,which have good sensitivity to reflect ventricular systolic,diastolic function and pre-and post-load.They have been widely used in various cardiovascular diseases.In recent years,many studies have shown that the plasma concentration of the two can be used to guide perioperative surgical treatment and evaluate the perioperative prognosis risk of children with CHD.This article reviews the application of BNP and NT-ProBNP in children with CHD with heart failure,especially during perioperative period.
