OBJECTIVE: To explore the genetic basis for a Chinese pedigree affected with inherited afibrinogenemia. METHODS: For the proband and his family members, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), Fibrin(ogen) degradation products (FDPs), D-dimer (D-D), plasminogen activity (PLG:A) and the TT mixed experiment with protamine sulfate were determined with a STAGO-R automatic coagulation analyzer. The activity and antigen of fibrinogen (Fg) in plasma were measured with the Clauss method and immunonephelometry method, respectively. All exons and flanking regions of the fibrinogen genes (FGA, FGB and FGG) were amplified by PCR and directly sequenced. Human Splicing Finder software was used to predict and score the change of splicing site caused by the mutation. RESULTS: The proband showed normal FDPs and D-D but significantly prolonged TT, PT and APTT. The activity and antigen of fibrinogen in plasma were significantly decreased (<0.1 g/L). His young sister and parents showed slightly prolonged TT (18.20-18.50 s) and decreased fibrinogen activity (1.27-1.54 g/L) and fibrinogen antigenic content (1.34-1.56 g/L). Genetic testing revealed that the proband has carried homozygous IVS7-12A>G (g.4147A>G) mutations of the FGG gene, for which his parents and young sister were heterozygous. As predicted by Human Splicing Finder and Mutation Taster software, the variant may generate a new splicing site which can extend the sequence of exon 7 by 11 bp, with alteration of the coding sequence. PROVEAN suggested the variant to be deleterious. CONCLUSION The afibrinogenemia of the proband may be attributed to the FGG IVS7-12A>G variant, which was unreported previously.

Objective To investigate the advantage of the concept of wide exposure in uniportal video-assisted thoracoscopic surgery (uniportal-VATS) for radical resection of lung cancer and assess its safety and feasibility. Methods Clinical data of 255 patients (110 males and 145 females, a mean age of 54.3±7.9 years) with non-small cell lung cancer (NSCLC) who received wide exposure in uniportal-VATS or three portal VATS (3P-VATS) during August 2017 to March 2018 were retrospectively analyzed. There were 153 patients (67 males and 86 females, a mean age of 56.1±8.5 years) in the uniportal-VATS group and 102 patients (43 males and 59 femals, a mean age of 54.4±7.4 years) in the 3P-VATS group. The clinical effects were compared between the two groups. Results There was no statistical difference in the operation time between the uniportal-VATS and 3P-VATS (135.0±45.6 min vs. 142.0±39.5 min, P>0.05). The overall number of dissected stations (6.9±1.0) and LNs (14.5±3.0) in the uniportal-VATS group were similar with those in the 3P-VATS group (7.1±1.0, 15.1±1.7). The dissected stations of N2 LNs (uniportal-VATS: 4.1±1.7, 3P-VATS: 3.9±0.8) and number of dissected N2 LNs (uniportal-VATS: 8.0±0.9, 3P-VATS: 7.8±1.1) were both similar between the two groups. The duration of postoperative tube drainage and postoperative hospital stay of uniportal-VATS group (3.5±1.8 d and 7.2±0.9 d) were much shorter than those of 3P-VATS group (4.0±1.3 d and 8.8±2.0 d). No significant difference was found in incidence of postoperative complication between the two groups except that the incidence of subcutaneous emphysema in the uniportal-VATS group was much lower. There was no perioperative death in the two groups. Conclusion The concept of wide exposure in uniportal-VATS can meet the requirment of radical resection and it is a safe and valid method which can be used for radical resection of lung cancer.

Curettage is the main treatment method for oral maxillofacial cystic lesions,but simple curettage may easily damage surrounding structures such as adjacent teeth and nerves,leading to incomplete removal of the cyst and large jaw defects.The curettage assisted by endoscopy can provide a good surgical field for the surgeons,can clearly identify the important anatomical structure during the operation and can remove the cyst wall tissue as much as possible,thereby reducing the damage and reducing the recurrence rate of the lesion.This article combines the characteristics of maxillofacial surgery with clinical treatment experience,summarizes relevant literature from both domestic and international sources,and engages in discussions with experts in order to provide reference for the clinical treatment of jaw cystic lesions with endo-scope assisted curettage.
