Objective To observe the efficacy of orbital septum fat repositioning through conjunctival approach in the correction of lower eyelid bags with tear trough deformity. Methods From January to June 2021, 30 patients with lower eyelid bags and tear trough deformity were selected. The orbital septum fat repositioning through conjunctival approach was performed. The tear trough before and after operation was evaluated by Barton's grading system. The efficacy was analyzed. Results All incisions healed well. No complications such as hematoma, infection and lower eyelid retraction occurred. There were 48 eyes with grade 1 before operation. At 1 month after operation, 46 eyes (95.8%) improved to grade 0 and 2 eyes (4.2%) did not improve. There were 12 eyes with grade 2 before operation. At 1 month after operation, 8 eyes (66.7%) improved to grade 0, 3 eyes (25.0%) improved to grade 1 and 1 eye (8.3%) did not improve. Conclusion For patients with lower eyelid bags, tear trough deformity and without obvious skin laxity, orbital septum fat repositioning through conjunctival approach is a safe and effective method.

Objevtive: To explore the effect of percutaneous transforaminal endoscopic discectomy for the treatment of lumbar disc herniation. Methods: 77 patients with lumbar disc herniation treated in our hospital from January 2018 to March 2020 were selected as the research subjects. They were divided into two groups by random number table according to the order of admission. 39 patients in the control group were given open surgery: posterior lumbar discectomy, intervertebral fusion, pedicle screw internal fixation, and 38 patients in the study group were treated with percutaneous endoscopic. Compare the recovery of lumbar function after treatment between two groups of patients. Comparison of clinical indicators such as surgical time, intraoperative blood loss, length of hospital stay, and incision length between the two groups of patients. The levels of interleukin-1β (IL-1β) and C-reactive protein (CRP) were compared between the two groups of patients before and 1 day after surgery. Results: The total excellent rate of waist function recovery in the study group was 92.11 % (35/38), which was significantly higher than that of the control group. The total excellent rate of waist function recovery was 66.67 %(26/39) (P<0.05). Intraoperative blood loss, length of hospital stay, length of incision, and operation time were significantly less (shorter) in the study group than in the control group (P<0.05). Before surgery, there was no significant difference in the levels of IL-1β and CRP between the two groups of patients (P>0.05). One day after surgery, the levels of IL-1β and CRP in the two groups were significantly higher than before surgery, but the study group was significantly lower than the control group (P<0.05). Conclusions: Percutaneous intervertebral foramen is effective in treating lumbar intervertebral disc herniation. This method can effectively improve the clinical indicators of patients, and has less damage to patients. It is recommended to be widely used in clinical practice. [ABSTRACT FROM AUTHOR]

Objective To construct the human pigment epithelium-derived factor (hPEDF) lentiviral vector, package lentivirus overexpressing PEDF and construct the human keratinocyte (HaCaT) cell line overexpressing PEDF. Methods The PEDF gene was inserted to lentiviral vector pLVX-IRES-puro to construct pLVX-IRES-puro-PEDF lentivirus recombinant plasmid. The pLVX-IRESpuro-PEDF lentivirus recombinant plasmid was transfected into 293T cells. The virus was packaged and amplificated. The virus supernatant was collected and the titer after amplification was authenticated. In the experimental group, HaCaT cells were infected with the constructed pLVX-IRES-puro-PEDF; whereas in the control group, HaCaT cells were infected with lentivirus containing empty vector. After amplification of 72 h, the HaCaT cells in both groups and conditioned medium were collected. The expression of PEDF mRNA in HaCaT cells of each group was detected by real-time PCR (RT-PCR) and the expression of PEDF protein was detected by western blot (WB). The PEDF protein secretion of HaCaT cells in both groups was detected by enzyme-linked immunosorbent assay (ELISA). Results It was confirmed that the recombinant lentivirus vector carrying PEDF gene was successfully constructed by using restriction enzyme digestion and Sanger sequencing. The titer of packaged lentivirus was up to 1×107 pfu/ml. The RT-PCR and WB results revealed that the expression of PEDF mRNA and protein in experimental group was significantly higher than that in the control group (P<0.05). Conclusion The recombinant lentiviral vector carrying PEDF gene was successfully constructed, and the HaCaT cell line infected with packaged lentivirus could over-express PEDF in vitro.
