To investigate the effectiveness and safety of diverticular peroral endoscopic myotomy (D-POEM) for mid-esophageal diverticulum. Data of consecutive patients in the prospective database with mid-esophageal diverticulum who received D-POEM in West China Hospital, Sichuan University between April 2014 to September 2019 were collected. The modified Eckardt scoring system for mid-esophageal diverticulum was used to evaluate the severity of diverticular symptoms. The effectiveness and safety of D-POEM were evaluated in terms of clinical success, technical success, complications and recurrence. A total of 7 patients with mid-esophageal diverticulum were included. Clinical and technical success was achieved in all patients with operation time of 16-70 minutes. No serious complications (2 cases with minor complications) or recurrence occurred. The follow-up time was 2-16 months. The median modified Eckardt score decreased from 3 points before operation to 0 points after operation. It is preliminarily believed that D-POEM ensures a complete septotomy between normal esophageal lumen and esophageal diverticulum. It is a safe and effective technique for mid-esophageal diverticulum. The modified Eckardt scoring system is suitable for symptom evaluation before and after treatment of mid-esophageal diverticulum.

Inflammatory caspase-11 senses and is activated by intracellular lipopolysaccharide (LPS) leading to pyroptosis that has critical role in defensing against bacterial infection, whereas its excess activation under pathogenic circumstances may cause various inflammatory diseases. However, there are few known drugs that can control caspase-11 activation. We report here that scutellarin, a flavonoid from Erigeron breviscapus, acted as an inhibitor for caspase-11 activation in macrophages. Scutellarin dose-dependently inhibited intracellular LPS-induced release of caspase-11p26 (indicative of caspase-11 activation) and generation of N-terminal fragment of gasdermin D (GSDMD-NT), leading to reduced pyroptosis. It also suppressed the activation of non-canonical nucleotide-binding oligomerization domain-like receptor family pyrin domain containing 3 (NLRP3) inflammasome as evidenced by reduced apoptosis-associated speck-like protein containing a CARD (ASC) speck formation and decreased interleukin-1 beta (IL-1β) and caspase-1p10 secretion, whereas the NLRP3-specific inhibitor MCC950 only inhibited IL-1β and caspase-1p10 release and ASC speck formation but not pyroptosis. Scutellarin also suppressed LPS-induced caspase-11 activation and pyroptosis in RAW 264.7 cells lacking ASC expression. Moreover, scutellarin treatment increased Ser/Thr phosphorylation of caspase-11 at protein kinase A (PKA)-specific sites, and its inhibitory action on caspase-11 activation was largely abrogated by PKA inhibitor H89 or by adenylyl cyclase inhibitor MDL12330A. Collectively, our data indicate that scutellarin inhibited caspase-11 activation and pyroptosis in macrophages at least partly via regulating the PKA signaling pathway.

Objective:To investigate the clinical effect of digital technology in the treatment of secondary deformity of orbitozygomatic fracture.Methods:The clinical data of 20 patients with secondary deformity of orbitozygomatic fracture treated in the Department of Plastic Surgery, the First Affiliated Hospital of Air Force Medical University from October 2015 to May 2019 were retrospectively analyzed, including 14 males and 6 females, aged 18-56 years. A computed tomography scan of the skull was performed before the operation. The data was three-dimensional(3D) reconstructed by Mimics software. The digital model was used to determine the surgical plan. Then the 3D head model was printed, osteotomy guide plate and reduction guide plate were used to guide osteotomy and reduction during surgery. Using Mimics software, the angle between orbital horizontal level and bilateral tragus linkage(A-OT value), the absolute value of the distance difference between bilateral zygomatic process point and facial midline (face width difference), and the absolute value of the distance difference between bilateral zygomatic process points and the vertical line passing through the central point of bony external auditory canal(facial process difference) were measured before and 3 days after operation. The exophthalmos of the affected side was measured by Hertel exophthalmos meter before and 6 months after operation. The paired t-test was used for comparison before and after operation. P<0.05 was statistically significant. Results:All the wounds healed well and the 20 patients were followed up for 6 months to 3 years. Before and after surgery, the A-OT values were (8.41 ± 2.46)° and (2.67 ± 0.55)°, with statistically significant difference ( t=11.242, P<0.001). Face width differences were (9.12 ± 1.02) mm and (1.51 ± 0.40) mm, with statistically significant difference( t=33.946, P<0.001). Facial process differences were (9.22 ± 0.95) mm and (1.53 ± 0.61) mm, with statistically significant difference ( t=33.484, P<0.001). Except for 4 patients with enucleation, the exophthalmos of the other patients was (7.81 ± 1.25) mm before operation and (12.78 ± 0.65) mm 6 months after operation. The difference was statistically significant ( t=-13.183, P<0.001). There was no diplopia and abnormal eye movement after operation. Conclusions:The application of digital technology in the treatment of secondary deformity of orbitozygomatic fracture is helpful to accurately diagnosis and reduction, and to improve the surgical effect.

Objective To explore a better method to repair cervical cicatricle contracture deformity.Methods The cervicai cicatrical contraction deformity was repaird by the cervico-shoulder island skin flap with blood supply crossing and abundant anastomotic branches of the neck-shoulder blood vessels. After removing the cervical scar, the flaps were designed according to the size of the wound to be repaired, and the clinical anatomy of crossing and abundant anastomotic branches of the neck-shoulder blood vessels. The secondary wound of donor site was closed directly if the donor region was small, or closed by skin graft. Results Sixteen patients in this clinic were operated with this method, and venous return dysfunction occurred in 1 case, but blood circulation was improved after treatment. All the flaps survived with good appearance and texture. The extensive flap was created and transferred to the anterior neck by one stage without pre-expansion which met some patients'requirement of repairing cervical cicatricle contracture deformity. Conclusion The cervico-shoulder island skin flap, with abundant blood supply, is a new method to repair cervical cicatricle contracture deformity.

AIM: To investigate the anti-HIV-1 activity of five anthraquinone derivatives (emodin,rhein,chrysophanol,physcion and aloe-emodin) in vitro.METHODS: Viral replication was estimated by observation of cytopathogenesis and measurement of HIV-1 p24 antigen production in HIV-1ⅢB acutely infected C8166 cells. The anti-HIV-1 activity was evaluated by the 50% effective concentrations (EC50) and selective indexes (SI) of these derivatives.RESULTS: These anthraquinone derivatives inhibited HIV-1ⅢB replication on syncytia formation induced by HIV-1ⅢB infection with EC50 mean values of (11.44±0.93)μmol/L (emodin),(51.28±2.86)μmol/L (rhein),(90.58±2.30)μmol/L (chrysophanol),(8.59±0.38)μmol/L (physcion) and (0.89±0.08)μmol/L (aloe-emodin),respectively. The p24 antigen production with EC50 mean values were (11.61±0.56)μmol/L (emodin),(12.35±4.73)μmol/L (rhein),(39.63±2.87)μmol/L (chrysophanol),>250 μmol/L (physcion) and (2.75±0.20)μmol/L (aloe-emodin) respectively. CONCLUSION: These structurally-related chemicals show different anti-HIV-1 activity in vitro. Among them,aloe-emodin is the most potent inhibitor to HIV-1 replication.
