Objective To investigate the effectiveness of sequential plate internal fixation in the correction of Madelung deformity after ulnar osteotomy and shortening. Methods The clinical data of 13 patients with Madelung deformity admitted between September 2015 and July 2021 were retrospectively analyzed. There were 5 males and 8 females with an average age of 18.3 years ranging from 17 to 23 years. The disease duration ranged from 12 to 24 months, with an average of 17 months. Three cases had a clear history of trauma. All patients had external radial deviation deformity and limited movement of the ulnar deviation, and the ulnar impact pain was significant during ulnar deviation movement; 9 patients had limited wrist joint supination movement, and the supination movement was normal. In the first stage, ulnar osteotomy and shortening combined with external fixator were used to correct wrist deformity in 13 patients. After operation, bone transfer was performed 6 times per day, with adjustments made every 4 hours, which was 1 mm per day. After the osteotomy was in place, the ulnar plate internal fixation was performed to reconstruct the ulnar stability in the second stage. The Cooney wrist joint score was used to assess the pain, function, range of motion, flexion and extension range of motion, and grip strength of the wrist joint before operation and before the removal of internal fixator. The subjective feeling and appearance satisfaction of patients were recorded. ResultsAfter the second-stage operation, all the 13 patients were followed up 10-22 months, with an average of 15 months. The deformity of wrist joint disappeared after operation, and the flexion, extension, and ulnar deviation were basically normal. There was no complication such as ulnar impingement sign, nonunion or infection. Wrist function, pain, and range of motion were significantly improved after operation, except for 1 patient who had no significant improvement in rotation and pain. The ulnar internal fixator was removed at 10-18 months after the second-stage operation. The scores of pain, function, range of motion, flexion and extension range of motion, and grip strength in the Cooney wrist score before removal of internal fixator significantly improved when compared with those before operation (P<0.05). Subjective and appearance satisfaction of patients were excellent in 9 cases, good in 3 cases, and fair in 1 case. ConclusionUlnar osteotomy and shortening with sequential plate internal fixation for correction of Madelung deformity, with mild postoperative pain, can effectively avoid bone nonunion, improve wrist joint function, and have significant effectiveness.

With the development of technology, the detection rate of ground-glass opacity (GGO) is rapidly increasing. GGO comprises of pure GGO and mixed GGO. Many researches have studied the characteristics of GGO, and they found that different malignant probability of GGO was associated with different image characteristics. It is obvious that there is a close relationship between the image characteristics of GGO and its prognosis. However, due to the various image characteristics of GGO, it is essential to assess the prognosis of lung adenocarcinoma patients in a more comprehensive way. In this review, we summarize the correlation between the main GGO image features (solid proportion, size, mean CT value, shape characteristics) and the prognosis of lung adenocarcinoma patients, to provide clinical reference for prognosis prediction and decision-making for patients with lung adenocarcinoma.

The postoperative hospitalization time was 5 (3-7) d. The pain score for the first 3 days after surgery was 3±1 points.ConclusionSingle utility port robot-assisted lung resection via anterior approach is safe, less traumatic, more convenient and effective, which can be gradually promoted and applied to clinical trials.
Objective To investigate the effects of different levels of intra-abdominal pressure ( IAP) on respiration and hemodynamics in a porcine model of acute lung injury( ALI) .Methods A total of 8 domestic swine received mechanical ventilation. Following baseline observations, oleic acid 0. 1mL/kg in 20mL of normal saline was infused via internal jugular vein. Using a nitrogen gas pneumoperitongum, the IAP increased from0 to 15 and 25mmHg, and the groups were named IAP0 , IAP15 and IAP25 , respectively. During the experimental period, hemodynamic parameters including heart rate ( HR) , cardiac output ( CO) , mean arterial pressure( MAP) , central venous pressure( CVP) , intrathoracic blood volume index( ITBVI) and so on were obtained by using thermodilution technique of pulse induced continuous cardiac output( PiCCO) . The esophageal pressure( Pes) was dynamicly monitored by the esophageal catheter. Results Pes and peak airway pressure( Ppeak) increased and static lung compliance( Cstat) decreased significantly in IAP15 and IAP25 groups compared with IAP0 group( all P lt;0. 01) . Transpulmonary pressure( Ptp) showed a downward trend( P gt;0. 05) . PO2 and oxygenation index showed a downward trend while PCO2 showed a upward trend ( P gt;0. 05) . HR and CVP increased significantly, cardiac index( CI) and ITBV index decreased significantly ( all P lt;0. 05) ,MAP didn′t change significantly( P gt;0. 05) . The changes in Pes were negatively correlated with the changes in CI( r = - 0. 648, P = 0. 01) . Conclusion In the porcine model of ALI, Pes increases because of a rise in IAP which decreased pulmonary compliance and CI.
Objective To evaluate the diagnostic value and safety of surgical lung biopsies ( SLB)in patients with interstitial lung disease ( ILD) . Methods A retrospective analysis was performed on patients undergoing SLB, who were obtained from Chinese literatures through searching PubMed, CBM,Wanfang database, VIP information and CHKD from 2000 to 2010. The data from Affiliated Drum Tower Hospital, Nanjing University Medical College from2000 to 2010 was also reviewed. Results A total of 398cases underwent SLB, including open lung biopsy ( OLB) in 221 cases and video-assisted thoracoscopic lung biopsy ( VATLB) in 177 cases. SLB yielded a specific diagnosis for 386 cases. The total postoperative complication rate was 12. 1% and mortality rate was 2. 0% . The diagnostic yield, post-operative complication rate, and mortality rate between VATLB and OLB had no significant difference. Conclusion SLB is a useful and relatively safe procedure for diagnosis of ILD.
Objective To improve accuracy of clinical diagnosis through analyzing the CT characteristics and clinical manifestations of patients with benign lung diseases whose CT manifestations initially led to a suspicion of lung cancer. Methods This study collected 2 239 patients of benign lung disease verified by postoperative pathology in the Department of Thoracic Surgery, Beijing Chao-yang Hospital from June 2006 to December 2016. Lesions of 173 patients (101 males and 72 females with a mean age of 56.0 years) were considered very likely to be malignant on preoperative contrast CT scan, which were sorted to 20 types of lung diseases, and the 20 types of diseases contained 907 patients diagnosed or misdiagnosed. Statistical analyses were performed using the CT and clinical characteristics of the 173 patients. Results Among the 907 patients with benign lung disease, the benign pathologies that were most commonly misdiagnosed by preoperative enhanced CT were pulmonary leiomyoma (100.0%), pulmonary actinomycosis (75.0%), pulmonary cryptococcosis (71.4%), sclerosing hemangioma (50.0%) and organizing pneumonia (44.2%). Among the 173 patients with benign diseases, the most common diseases were tuberculosis (29.5%), organizing pneumonia (28.9%), pulmonary hamartoma (6.4%) and pulmonary abscess (6.4%). In the 173 patients, 17.3% had fever, 56.6% coughing, 8.7% yellow sputum, 28.9% hemoptysis, 16.2% chest pain, 18.5% elevated leukocyte counts and 4.6% elevated carcinoembryonic antigen levels. Most of the CT manifestations consisted of nodular or mass shadows, 70.5% of which had foci≤3 cm and manifestations were similar to those of lung cancer, such as a spiculated margin (49.1%), lobulation (33.5%), pleural indentation (27.2%) and significant enhancement (39.3%). Furthermore, some patients had uncommon tumor signs, such as calcification (12.7%), central liquefactive necrosis (18.5%), satellite foci (9.8%) and multiple pulmonary nodules (42.2%). Moreover, 24.3% of the patients had enlarged lymph nodes of the mediastinum or hilum. Conclusion As the CT manifestations of some benign lung conditions are similar to those of lung cancer, careful differential diagnosis is necessary to identify the basic characteristics of the disease when the imaging results are ambiguous, and the diagnosis of a lung disease need incorporate the patients' clinical characteristics and a comprehensive analysis.
Objective Review the status of the direct health cost of nonsmall-cell lung cancer , and to put forward policy recommendations. Methods Database including PubMed, Cochrane Library and Chinese BioMed were searched, and studies literatures about the direct health cost of nonsmall-cell lung cancer. Results Twenty two studies were analyzed in this paper including 20 foreign studies. Normally, international researches about direct medical cost of treating the nonsmall-cell lung cancer investigate total cost from the first diagnosis until several years later. The discrepancy in the results could be explained by different payments, treatment patterns and research methods in different countries. The direct medical cost of nonsmall-cell lung cancer is expensive especially the cost of in-patient. It’s increase with the time of therapy. Most of the researches in China about direct medical cost of nonsmall-cell lung cancer focus on per in-patient fees. Conclusion Facing the increasingly heavy economic burden of nonsmall-cell lung cancer, to lower the incidence of this disease and to reduce the treatment related cost should be taken into account., the prevention of nonsmall-cell lung cancer carcinoma should be enhanced, Such as tobacco control, environment improvement, etc. A proper incentive mechanism should be established.
Objective To explore the clinical value of artificial intelligence (AI) quantitative parameters of pulmonary ground-glass nodules (GGN) in predicting the degree of infiltration. Methods A retrospective analysis of 168 consecutive patients with 178 GGNs in our hospital from October 2019 to May 2021 was performed, including 43 males and 125 females, aged 21-78 (55.76±10.88) years. Different lesions of the same patient were analyzed as independent samples. Totally, 178 GGNs were divided into two groups, a non-invasive group (24 adenocarcinoma in situ and 77 minimally invasive adenocarcinoma), and an invasive group (77 invasive adenocarcinoma). We compared the difference of AI quantitative parameters between the two groups, and evaluated predictive valve by receiver operating characteristic curve and binary logistic regression model. Results (1) Except for the gender (P=0.115), the other parameters, such as maximal diameter [15.10 (11.50, 21.60) mm vs. 8.90 (7.65, 11.15) mm], minimum diameter [10.80 (8.85, 15.20) mm vs. 7.40 (6.10, 8.95) mm], proportion of consolidation/tumor ratio [13.58% (1.61%, 63.76%) vs. 0.00% (0.00%, 0.67%)], mean CT value [–347.00 (–492.00, –101.50) Hu vs. –598.00 (–657.50, –510.00) Hu], CT maximum value [40.00 (–40.00, 94.50) Hu vs. –218.00 (–347.00, –66.50) Hu], CT minimum value [–584.00 (–690.50, –350.00) Hu vs. –753.00 (–786.00, –700.00) Hu], danger rating (proportion of high-risk nodules, 92.2% vs. 66.3%), malignant probability [91.66% (85.62%, 94.92%) vs. 81.81% (59.98%, 90.29%)] and age (59.93±8.53 years vs. 52.04±12.10 years) were statistically significant between the invasive group and the non-invasive group (all P<0.001). (2) The highest predictive value of a single quantitative parameter was the maximal diameter (area under the curve=0.843), the lowest one was the risk classification (area under the curve=0.627), the combination of two among the three parameters (maximal diameter, mean CT value, and consolidation/tumor ratio) improved the predictive value entirely. (3) Logistic regression analysis showed that maximal diameter and mean CT value both were the independent risk factor for predicting invasive adenocarcinoma. (4) When the threshold of v was 1.775%, the diagnostic sensitivity of invasive adenocarcinoma was 0.753 and the specificity was 0.851. Conclusion AI quantitative parameters can effectively predict the degree of infiltration of GGNs and provide a reliable reference basis for clinicians.
With the growth of offshore activities, the incidence rates of seawater drowning (SWD) induced acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) increase significantly higher than before. Pulmonary interstitial edema, alveolar septum fracture, red blood cells, and inflammatory cells infiltration can be seen under light microscope in the pathologic changes of lungs. The major clinical manifestations are continual hyoxemia and acidosis, which lead to a severe condition, a high death rate, and a poor treatment effect. Bone marrow mesenchymal stem cells are capable of self-renewal, multilineage differentiation and injured lung-homing, which are induced to differentiate into alveolar epithelial cells and pulmonary vascular endothelial cells for tissues repairing. This may be a new way to treat SWD-ALI and SW-ARDS.
