Objective:To compare the clinical outcomes of endovascular therapy in acute stroke patients with anterior circulation tandem occlusions caused by atherosclerosis or dissection.Methods:A retrospective cohort study. A total of 98 patients with anterior circulation tandem lesions undergoing endovascular therapy in the Wuhan NO.1 Hospital (March 2016 to March 2022) were analyzed. Median age was 64(55,71) years old, and 82.7% (81/98 cases) were males. According to the lesion etiology, the patients were divided into atherosclerosis and dissection groups. The differences in clinical outcomes between the two groups were investigated, including favorable 90-day functional outcome (modified Rankin Scale score of 0-2), successful reperfusion (modified Thrombolysis in Cerebrovascular Infarction score of 2b-3), symptomatic intracranial hemorrhage, stroke-associated pneumonia, 90-day all-cause mortality, and average hospitalization days. Logistic regression analysis was used to adjust for potential confounders affecting functional outcomes in both groups, and to determine odds ratios and 95% confidence intervals.Results:Seventy-one patients were grouped into the atherosclerotic cause and 27 into the dissection cause cohorts. The rate of favorable 90-day functional outcome was 43.7% (31/71 cases) in the atherosclerosis group versus 55.6% (15/27 cases) in the dissection group (adjusted odds ratio=1.339; 95% confidence interval, 0.374-4.798; P=0.654). No significant differences were found in other clinical outcomes between the two groups (all P>0.05). Conclusion:The clinical prognosis of patients with tandem lesions caused by atherosclerotic stenosis or artery dissection was similar after endovascular therapy. Future studies are still needed to verify our results.

Objective:To investigate the clinical effect of orbicularis oculi muscle(OOM)-septoaponeurosis junctional thickening area (SAJT)fixation technique in double eyelid plasty.Methods:From June 2016 to March 2019, patients who received double eyelid blepharoplastyby OOM-SAJT technology in plastic surgery department of Affiliated Hospital of Nanjing University of Traditional Chinese Medicine were retrospectively analyzed. All the patients underwent double eyelid surgery for the first time or only received catgut embedding surgery. During the operation, the orbital septum was opened and the remnant of the orbital septum was trimmed to expose the SAJT fixation. The dermis and orbicularis oculi muscle of the lower flap were sutured to the SAJT fixation. The symmetry, fluency, shedding or shallowing, wound healing, scar and complications of double eyelid were observed after operation.Results:A retrospective review of 1 384 patients (136 males and 1 248 females, aged from 17 to 45) who had undergone double eyelid surgery using OOM-SAJT fixation technique were collected. All patients, in which 1 173 cases underwent double eyelid operation for the first time and 211 cases of revision surgery were performed successfully. All the incisions healed without obvious hematoma and swelling. There were 12 cases of double eyelid disappearance, 8 cases of asymmetry, 9 cases of irregularity. But in most patients, the curvature of the double eyelid is natural and smooth, the eyelashes are upturned dynamically with their eyes open, and the skin of upper eyelid is flat when their eyes are closed without obvious depression, scar or fleshy phenomenon.Conclusions:The double-eyelid surgery using OOM-SAJT fixation technique can result in double eyelids close to physiological anatomical structure. This technique is applicable, anatomically compatible, and results in stable double eyelids.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

BACKGROUND: Bronchopleural fistula (BPF) is one of the most serious and rare postoperative complications, especially the bronchial stump fistula after lobectomy/pneumonectomy. Common treatment options include conservative medical treatment combined with surgery. However, due to the delayed healing of the fistula, the chest cavity continues to communicate with the outside world, and the patient is prone to complicated with severe thoracic infection and respiratory failure, so that the physical condition can hardly tolerate the second surgical procedure. Endoscopic treatment provides a new option for the treatment of this complication. METHODS: A case of right pulmonary squamous cell carcinoma was admitted to the Department of Thoracic Surgery II, Peking University Cancer Hospital in June 2016. The diagnosis and treatment was retrospectively analyzed, and the literature was reviewed. RESULTS: A 65 year old male patient was admitted to hospital because of "cough with blood in sputum for 3 months". Chest computed tomography (CT) showed soft tissue density mass shadow in the right lower lobe. A tumor could be seen in the opening of the right middle lobe and basal segment of lower lobe. Biopsy confirmed squamous cell carcinoma. Diagnosis consideration: squamous cell carcinoma of the middle and lower lobe of the right lung (cT2aN2, IIIa). Patients received gemcitabine plus cisplatin neoadjuvant chemotherapy for 2 cycles, and the effect of chemotherapy showed stable disease (SD). Four weeks after chemotherapy, the patient underwent video-assisted thoracic surgery (VATS) assisted right middle and lower lobectomy and mediastinal lymph node dissection. On the 5th day after operation, the patient developed acute respiratory distress syndrome (ARDS) and was transferred to intensive care unit (ICU) again after endotracheal intubation. On the 7th day after operation, the patient developed a right intermediate trunk bronchial stump fistula, but due to ARDS, the patient's physical condition could not tolerate the second operation. Under the support of extracorporeal membrane oxygenation (ECMO), a membrane covered, expandable, hinged stent was inserted into the intermediate trunk bronchial stump through rigid bronchoscope, and was successfully blocked. Due to no improvement in ARDS and irreversible pulmonary interstitial fibrosis, the patient received double lung transplantation successfully after systemic anti-infection treatment. CONCLUSIONS Endoscopic implantation of covered stent is a simple, safe and effective method for closure of bronchial stump fistula. When the patient's clinical situation is not suitable for immediate surgery, endoscopic stent implantation can be used as a preferred treatment method to create opportunities for follow-up treatment.

Objective:By analyzed the transmission patterns of 4 out of the 51 COVID-19 cluster cases in Shaanxi province to provide evidences for the COVID-19 control and prevention.Methods:The epidemiological data of RT-PCR test-confirmed COVID-19 cases were collected. Transmission chain was drawn and the transmission process was analyzed.Results:Cluster case 1 contained 13 cases and was caused by a family of 5 who traveled by car to Wuhan and returned to Shaanxi. Cluster case 2 had 5cases and caused by initial patient who participated family get-together right after back from Wuhan while under incubation period. Cluster case 3 contained 10 cases and could be defined as nosocomial infection. Cluster case 4 contained 4 cases and occurred in work place.Conclusion:Higher contact frequency and smaller places were more likely to cause a small-scale COVID-19 cluster outbreak, with potential longer incubation period. COVID-19 control strategies should turn the attention to infection prevention and control in crowded places, management of enterprise resumption and prevention of nosocomial infection.

Objective:To understand the incidence trend and epidemiological characteristics of COVID-19 in Shaanxi province.Methods:The incidence data of COVID-19 reported in Shaanxi as of 22 February, 2020 were collected for an epidemiological descriptive analysis.Results:A total of 245 confirmed cases of COVID-19 were reported in Shaanxi. Most cases were mild (87.76%). As time passed, the areas where confirmed cases were reported continued to increase. The case number in Xi’an was highest, accounting for nearly half of the total reported cases in the province. The epidemic pattern in Shaanxi had gradually shifted from imported case pattern to local case pattern, and the transmission of local cases was mainly based on family cluster transmission. The confirmed cases from different sources had caused the secondary transmission in Shaanxi. After February 7, the number of reported cases began to fluctuate and decrease stably, indicating a decrease-to-zero period.Conclusions:At present, the overall epidemic of COVID-19 in Shaanxi has gradually been mitigated. However, considering the approaching of return to work and study and the increasing of imported cases from other countries, the prevention and control of COVIS-19 in Shaanxi will face new challenges.

BACKGROUND: IIIa-N2 non-small cell lung cancer was significant different in survival, although N stage of lung cancer based on anatomic location of metastasis lymph node. Lymph node ratio considered of prognostic factor might be the evaluation index for IIIa-N2 non-small cell lung cancer prognosis. Therefore, the aim of the study was to evaluate the correlation between lymph node ratio and clinicopathological features and prognosis of IIIa-N2 non-small cell lung cancer prognosis. METHODS: A total of 288 cases of pathological IIIa-N2 non-small cell lung cancer were enrolled who received radical resection at the Department of Thoracic Surgery II, Peking University Cancer Hospital from January 2006 to December 2016. The univariate analysis between clinicopathological variables and lymph node ratio used Pearson's chi-squared test. Cox regression was conducted to identify the independent prognosis factors for IIIa-N2 non-small cell lung cancer. RESULTS: There were 139 cases in the lower lymph node ratio group, another 149 cases in the higher lymph node ratio group. Adenocarcinoma (χ²=5.924, P=0.015), highest mediastinal lymph node metastasis (χ²=46.136, P<0.001), multiple-number N2 metastasis (χ²=59.347, P<0.001), multiple-station N2 metastasis (χ²=77.387, P<0.001) and skip N2 lymph node metastasis (χ²=61.524, P<0.001) significantly impacted lymph node ratio. The total number of lymph node dissection was not correlated with the lymph node ratio (χ²=0.537, P=0.464). Cox regression analysis confirmed that adenocarcinoma (P=0.008), multiple-number N2 metastasis (P=0.025) and lymph node ratio (P=0.001) were the independent prognosis factors of disease free survival. The 5-year disease free survival was 18.1% in the higher lymph node ratio group, and 44.1% in the lower. Lymph node ratio was the independent prognosis factor of overall survival (P<0.001). The 5-year overall survival was 36.7% in the higher lymph node ratio group, and 64.1% in the lower. CONCLUSIONS Lymph node ratio was correlative with the pathology, highest mediastinal lymph node metastasis, multiple-number N2 metastasis, multiple-station N2 metastasis and skip N2 lymph node metastasis. Lymph node ratio was the independent prognosis factor for IIIa-N2 non-small cell lung cancer.
