Objective To study the surgical techniques and the clinical curative ettect of the reconstruction of adjacent large finger pulps with the modified sensate free proximal ulnar artery perforator flap.Methods From February,2013 to May,2016,20 fingers in 10 patients with adjacent large finger pulp defects crossing the DIP joint were reconstructed by the modified senate free proximal ulnar artery perforator flap.All the pulps of every patient were recovered by 1 flap in the first stage and the artificial syndactyly of two digits was divided in 7 weeks after the flap transfer in the second stage.In order to reconstruct the sensation of two pulps in each patient,firstly both of the proximal and distal ends of the cutaneous nerve in flaps were dissected and anastomosed with the most lateral and medial palmar digital nerves of two adjacent fingers respectively,which were divided into 2 groups.Secondly the cutaneous nerve in the middle part of flap was cut and the two ends were anastomosed with the other two palmar digital nerves in the second surgery.There were 8 fingers in 4 patients with the index and middle finger pulp defects,12 fingers in 6 patients with the middle and ring finger defects.The flap size was from 5.0 cm×3.5 cm to 5.5 cm×4.0 cm,and the perforator artery was anastomosed with the palmar digital artery in 6 cases and with the joint branch of digital artery in 4 cases.Results Nine flaps survived uneventfully except the venous congestion was found in 1 flap which was salvaged successfully by acupuncture bleeding.Also,no congestion or ischemia of all the 20 pulp flaps occurred right after releasing the artificial syndactyly.The time of followed-up was from 11 months to 32 months with the average of 17 months after the second surgery.The static two point discrimination of the 2 groups of the sensate pulp flap was (7.3 ± 1.2) mm and (8.6 ±2.4) mm respectively.There was no significant difference between groups (P ＞ 0.05).These 20 pulp flaps were also assessed by the Semmes-Weinstein monofilament test with the result of diminished light touch in 14 pulps and diminished protective touch in 6 pulps.The total active motion in all 20 fingers was (248.0±4.5) °.No patients suffered cold intolerance and local pain but 1 had hypersensitiveness in the pulp flap.Conclusion The modified sensate free proximal ulnar arte~ perforator flap is a practical alternative for the reconstruction of two large adjacent pulps with satisfactory functional and aesthetic outcomes.

Objective    To analyze the expression and clinical significance of cyclin-dependent kinase 1 (CDK1) in lung adenocarcinoma by bioinformatics. Methods    Based on the gene expression data of lung adenocarcinoma patients in The Cancer Genome Atlas (TCGA), the differential expression of CDK1 in lung adenocarcinoma tissues and normal lung tissues was analyzed. The expression of CDK1 gene in lung adenocarcinoma was analyzed by UALCAN at different angles. Survival analysis of different levels of CDK1 gene expression in lung adenocarcinoma was performed using Kaplan-Meier Plotter. Correlation Cox analysis of CDK1 expression and overall survival was based on clinical data of lung adenocarcinoma in TCGA. Gene set enrichment analysis was performed on gene sequences related to CDK1 expression in clinical cases. The protein interaction network of CDK1 from Homo sapiens was obtained by STRING. CDK1-related gene proteins were obtained and analyzed by the web server Gene Expression Profiling Interactive Analysis (GEPIA). Results    Based on the analysis of TCGA gene expression data, CDK1 expression in lung adenocarcinoma was higher than that in normal lung tissues. UALCAN analysis showed that high CDK1 expression may be associated with smoking. Survival analysis indicated that when CDK1 gene was highly expressed, patients with lung adenocarcinoma had a poor prognosis. Univariate and multivariate Cox regression analysis of CDK1 expression and overall survival showed that high CDK1 expression was an independent risk factor for survival of patients with lung adenocarcinoma. Gene set enrichment analysis revealed that high CDK1 expression was closely related to DNA replication, cell cycle, cancer pathway and p53 signaling pathway. Conclusion    CDK1 may be a potential molecular marker for prognosis of lung adenocarcinoma. In addition, CDK1 regulation may play an important role in DNA replication, cell cycle, cancer pathway and p53 signaling pathway in lung adenocarcinoma.

Focal cortical dysplasia (FCD) is one of the most common causes of drug-resistant epilepsy. Dysmorphic neurons are the major histopathological feature of type II FCD, but their role in seizure genesis in FCD is unclear. Here we performed whole-cell patch-clamp recording and morphological reconstruction of cortical principal neurons in postsurgical brain tissue from drug-resistant epilepsy patients. Quantitative analyses revealed distinct morphological and electrophysiological characteristics of the upper layer dysmorphic neurons in type II FCD, including an enlarged soma, aberrant dendritic arbors, increased current injection for rheobase action potential firing, and reduced action potential firing frequency. Intriguingly, the upper layer dysmorphic neurons received decreased glutamatergic and increased GABAergic synaptic inputs that were coupled with upregulation of the Na⁺-K⁺-Cl^- cotransporter. In addition, we found a depolarizing shift of the GABA reversal potential in the CamKII-cre::PTEN^flox/flox mouse model of drug-resistant epilepsy, suggesting that enhanced GABAergic inputs might depolarize dysmorphic neurons. Thus, imbalance of synaptic excitation and inhibition of dysmorphic neurons may contribute to seizure genesis in type II FCD.
