Exploring the phytoconstituents targeting TNF-α as potential lead compounds to treat inflammatory diseases: an in-silico approach / 数字中医药（英文）

@#Objective To explore the anti-inflammatory phytoconstituents from various plant sources as tumour necrosis factor-α (TNF-α)-inhibitor, a mediator involved in the inflammatory disorder, by in silico molecular docking. Methods Based on previous findings, we performed the in silico assessment of anti-inflammatory phytoconstituents from different medicinal plants to understand their binding patterns against TNF-α (PDB ID: 6OP0) using AutoDock Vina. Molecular docking was performed by setting a grid box (25 × 25 × 25) Å centered at [– 12.817 × (– 1.618) × 19.009] Å with 0.375 Å of grid spacing. Furthermore, Discovery Studio Client 2020 program was utilized to assess two- and three-dimensional (2D and 3D) hydrogen-bond interactions concerning an amino acid of target and ligand. Physicochemical properties were reported using the Lipinski’s rule and SwissADME database to support the in silico findings. Results From the selected medicinal plants, more than 200 phytocompounds were screened against TNF-α protein with binding scores in the range of – 12.3 to – 2.5 kcal/mol. Amongst them, emodin, aloe-emodin, pongamol, purpuritenin, semiglabrin, ellagic acid, imperatorin, α-tocopherol, and octanorcucurbitacin A showed good binding affinity as – 10.6, – 10.0, – 10.5, – 10.1, – 11.2, – 10.3, – 10.1, – 10.1, and – 10.0 kcal/mol, respectively. Also, the absorption, distribution, metabolism, excretion, and toxicology (ADMET) profiles were well within acceptable limits. Conclusion Based on our preliminary findings, we conclude that the selected phytoconstituents have the potential to be good anti-inflammatory candidates by inhibiting the TNF-α target. These compounds can be further optimized and validated as new therapeutic components to develop more effective and safe anti-inflammatory drugs.

Ipsilateral open anterior hip dislocation and open posterior elbow dislocation in an adult / 中华创伤杂志(英文版)

Open anterior dislocation of the hip is a very rare injury, especially in adults. It is a hyperabduction, external rotation and extension injury. Its combination with open posterior dislocation of the elbow has not been described in English language-based medical literature. Primary resuscitation, debridement, urgent reduction of dislocation, and adequate antibiotic support resulted in good clinical outcome in our patient. At 18 months follow-up, no signs of avascular necrosis of the femoral head or infection were observed.

Pseudoaneurysm of profunda femoris artery following dynamic hip screw fixation for intertrochanteric femoral fracture / 中华创伤杂志(英文版)

Dynamic hip screw fixation is a commonly performed procedure for internal fixation of intertrochanteric femoral fractures. Arterial injury following the operative fixation is a rare but serious event. We present a patient who developed pseudoaneurysm of profunda femoris artery after internal fixation of intertrochanteric fracture with a dynamic hip screw. The diagnosis was confirmed by angiographic study and it was successfully treated by coil embolization.

Rare double fracture-dislocation of the thumb: a case report and review of the literature / 中华创伤杂志(英文版)

Simultaneous fracture/dislocation of the thumb carpometacarpal (CMC) joint and dislocation of the metacarpophalangeal (MCP) joint is considered as a rare injury pattern. We report an unusual case of dorsal dislocation of MCP joint of the thumb associated with extraarticular fracture of the base of the first metacarpal in a 28-year-old man. The dislocation of MCP joint had been missed during initial presentation at a peripheral centre. The patient made an uneventful recovery following open reduction and fixation with 1.25 mm Kirschner wire of the MCP joint along with repair of the ulnar collateral ligament. This injury pattern has not been previously reported to the best of our knowledge in the English-language based medical literature.

Missed posterior shoulder dislocation with malunited proximal humerus fracture / 中华创伤杂志(英文版)

Posterior dislocation of the shoulder may be missed or neglected at initial presentation especially in developing countries. We present a case of 40-year-old Indian man who had 3-month missed posterior dislocation of the right shoulder along with malunited fracture of the anatomical neck of the humerus. Open reduction and stabilization with modified McLaughlin procedure was performed. Rotational osteotomy of proximal humerus had to be performed as supplementary procedure to keep the humeral head stable in glenoid cavity during functional range of movements. The patient had excellent result of the shoulder at 3 years follow-up.
