Objective To investigate the features of lymph node metastasis and its effects on the prognosis of patients after radical operation for thoracic esophageal squamous cell cancer, and investigate the reasonable postoperative adjuvant protocol. Methods Multivariate analysis of the clinical data of 204 patients was carried out by Spearman correlation analysis, Cox model and Kaplan-Meier method. Results The lymph node metastasis rate was 40.2% (82/204), and 166 out of 2193 dissected lymph nodes had metastasis with the rate of 7.57%. The analysis of related factors revealed that the invasion depth, tumor length and differentiation grade were significantly associated with the postoperative lymph node metastasis (χ2 = 17.466, 11.494, 6.767, P <0.05), while age, tumor site were not significantly correlated with the postoperative lymph node metastasis (χ2=1.086, 3.897, P > 0.05). Kaplan-Meier analysis showed that the 1-, 3-, 5-year survival rates of patients with < 4 lymph nodes metastasis were significantly higher than those with ≥4 lymph nodes metastasis (χ2=4.493, 4.494, 4.450, P < 0.05). The recurrence and metastasis were more often occurred in patients with lymph node metastasis compared with those without lymph node metastasis (r=-2.060, -4.296, P <0.05). Multivariate analysis confirmed that the pathological stage, tumor differentiation grade, and the postoperative adjuvant treatment were the independent prognostic factors. Conclusions The invasion depth, tumor length and differentiation grade are significantly associated with the postoperative lymph node metastasis. The lymph node metastasis state and the number of involved lymph nodes affect the prognosis of patients. Oral administration of 5-FU is benefit to the patients without lymph node metastasis.

Objective:To investigate the efficacy and safety of surgery via endoscopic-assisted transcallosal approach in intraventricular hemorrhage (IVH).Methods:A retrospective study was performed; the clinical data of 68 IVH patients admitted to our hospital from October 2016 to January 2020 were analyzed. These patients were divided into endoscopic treatment group ( n=34) and drainage group ( n=34) according to the treatment methods. In the endoscopic treatment group, IVH was evacuated via endoscopic-assisted transcallosal approach; in the drainage group, external ventricular drainage and urokinase injection were performed. Gross hematoma clearance rate (clearance rate≥95%) 1, 3, and 7 d after surgery, complication incidence 7 d and 1 month after surgery, and good prognosis rate (ability of daily living [ADL] grading I-III) 3 months after surgery were compared between the two groups. Results:One, 3, and 7 d after surgery, the gross hematoma clearance rate in the endoscopic treatment group was significantly higher than that in the drainage group ( P<0.05). The recurrent hemorrhage rate within 7 d of surgery, intracranial infection rate, and percentage of patients with secondary hydrocephalus requiring shunt within 30 d of surgery in the endoscopic treatment group were significantly lower than those in the drainage group (2.9% vs. 20.6%, 2.9% vs. 23.5%, 5.9% vs. 17.6%, P<0.05). Three months after follow-up, the good prognosis rate of patients in the endoscopic treatment group was significantly higher than that in the drainage group (91.2% vs. 58.9%, P<0.05). Conclusion:Endoscopic-assisted transcallosal approach is recommended in clinical treatment of IVH, which can significantly reduce postoperative complications and improve postoperative prognosis.

Objective: To explore experience of wound treatment of extremely severe mass burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident. Methods: On August 2nd, 2014, 98 extremely severe burn mass patients involved in August 2nd Kunshan factory aluminum dust explosion accident were admitted to 20 hospitals in China. The patients with complete medical record were enrolled in the study and divided into microskin graft group with 56 patients and Meek skin graft group with 42 patients. Split-thickness skin in area of residual skin were resected to repair wounds of patients in microskin graft group and Meek skin graft group by microskin grafting and Meek miniature skin grafting, respectively. The residual wound size on 28 days post injury and wound infection after skin grafting of patients in the two groups, and position of donor site of all patients were retrospectively analyzed. Data were processed with t test and chi-square test. Results: The size of residual wound of patients in Meek skin graft group on 28 days post injury was (59±13)% total body surface area (TBSA), which was obviously smaller than that in microskin graft group [(70±14)%TBSA, t=4.379, P<0.05]. Twenty-nine patients in microskin graft group and 11 patients in Meek skin graft group suffered from obvious wound infection after skin grafting. Wounds of patients in two groups were repaired with residual skin around wound in head, trunk, groin, armpit, and uncommon donor sites of scrotum (4 patients), vola (10 patients), and toe or finger web (8 patients). Conclusions Meek skin graft is the first choice for wound repair of extremely severe burn mass patients, with faster wound healing, less wound infection. Uncommon donor sites of scrotum, vola, and toe or finger web can also be used for wound repair in case of lack of skin.

Background and objective As computed tomography (CT) screening for lung cancer becomes more common in China, so too does detection of pulmonary ground-glass nodules (GGNs). Although anumber of national or international guidelines about pulmonary GGNs have been published,most of these guidelines are produced by respiratory, oncology or radiology physicians, who might not fully understand the progress of modern minimal invasive thoracic surgery, and these current guidelines may overlook or underestimate the value of thoracic surgery in the management of pulmonary GGNs. In addition, the management for pre-invasive adenocarcinoma is still controversial. Based onthe available literature and experience from Shanghai Pulmonary Hospital, we composed this consensus about diagnosis and treatment of pulmonary GGNs. For lesions which are considered as adenocarcinoma in situ, chest thin layer CT scan follow-up is recommended and resection can only be adopt in some specific cases and excision should not exceed single segment resection. For lesions which are considered as minimal invasive adenocarcinoma, limited pulmonary resection or lobectomy is recommended. For lesions which are considered as early stage invasive adenocarcinoma, pulmonary resection is recommend and optimal surgical methods depend on whether ground glass component exist, location, volume and number of the lesions and physical status of patients. Principle of management of multiple pulmonary nodules is that primary lesions should be handled with priority, with secondary lesions taking into account.
