Twenty-one eyes of 13 patients with juvenile glaucoma confirmed by ocular tension, vision, eye ground and gonioscope underwent trabeculectomy combined with amniotic membrane transplantation. The posttransplant intraocular pressure significantly decreased compared to pretreatment (P

Objective To investigate new methods of osteonecrosis of femoral head (ONFH) with retrospective analysis of the clinical cases with technique of rotary cutting pressure-relief,impacted graft,and tantalum rod supporting treatment of early-stage femoral head necrosis.Methods From June 2010 to June 2014,32 cases (38 hips,23 males and 9 females) with ONFH were treated with technique of rotary cutting pressure-relief,impacted graft,and tantalum rod supporting,with the mean age of 24 ～ 52 (36.2 ± 3.8) years old.According to the Association Research Circulation Osseous (ARCO) classification,there were 11 hips on Ⅱ A stage,12 hips Ⅱ B,8 hips Ⅱ c,7 hips Ⅲ A.The averaged Harris score of all cases was 65 ～ 81 (72.5 ± 5.8) points.All cases were cured with minimally invasive technique,rotary cutter pressure-relief in femoral head,thoroughly remove sequestrum and implant allogeneic bone.Postoperative patients laid in bed for 1 month,after 1 month hold crutch gradually began to functional training.Postoperative 1 month,X ray film was reviewed every 3 months.According to the clinical symptoms,imaging findings,Harris scoring system was graded to evaluate the effectiveness.Results All the cases were followed up for average of 12 ～32 (20.2 ± 2.6) months,31 hips Kept hips succeed,hips pain; lame line symptoms were reduced or disappeared; x-ray showed femoral head necrosis area formed new bone,Harris scoring was upgraded to 75 ～ 95 (87.7 ± 6.4) points ; and seven hips failed with operation of total hip arthroplasty.The overall good rate was promoted from 26.3％ to 84.2％.Conclusions The technique treating for early-stagefemoral head necrosis with minimally invasive,rotary cutting pressure-relief,impacted graft,and tantalum rod supporting had a good short-term effects.

Object To define the optimal proportion of four ingredients in Danxintong (DXT). Methods Uniform design method combined with pharmacodynamics (Rat acute myocardial ischemia model was used in this study) was used. Results The optimal proportion and components of DXT (Composed of Rhizoma Chuanxiong, Rhizoma Cyperi, Borneolum Syntheticum, and paeonol) were 5∶ 1.7∶ 1.4∶ 4.4; DXT 138 mg/kg could obviously inhibit acute myocardial ischemia of rats induced by iso prenaline (Iso) and pituiturin (Pit). DXT has antimyocardial ischemia effects in preliminary experimental studies. Conclusion Uniform design method is an effective method to define the optimal proportion of ingredients in DXT;

Objective To investigate changes in coagulation function and inflammation levels during sepsis.Methods A rat model of sepsis was established using the multiple infection sepsis model(MIM)based on cecal ligation and puncture.Forty-eight male Sprague-Dawley rats were assigned randomly to the following groups:control group,sham group,4 h sepsis group,8 h sepsis group,12 h sepsis group,and 16 h sepsis group(n=8 per group).Inflammatory markers and coagulation-related indicators were measured by enzyme-linked immunosorbent assay and coagulation analysis.Results(1)Lipopolysaccharide(LPS)and interleukin-6(IL-6)levels were significantly higher in the model rats at all time points compared with the sham group(P＜0.001).LPS and IL-6 levels increased gradually with disease progression,with no further changes in LPS after 12 hours.(2)Prothrombin time(PT)was significantly prolonged in the middle and late stages of the sepsis model,starting from 8,compared with the sham group(P＜0.01).(3)Partially activated prothrombin time(APTT)time was significantly prolonged in the 8,12,and 16 h groups compared with the sham group(P＜0.05,P＜0.01).APTT gradually lengthened from 8 h,but approached control levels thereafter.(4)Fibrinogen(Fbg)content was significantly higher in all sepsis groups,except for the 8 h group,compared with the sham group(P＜0.01).(5)Fibrin degradation products(FDP)differed significantly between the control and sham groups(P＜0.01),but not between the sham and sepsis groups.(6)Antithrombin-Ⅲ(AT-Ⅲ)levels decreased significantly throughout each stage of sepsis progression compared with the sham group(P＜0.01),and AT-Ⅲ showed a downward trend with the course of disease,with significant differences among the 4,8,and 16 h groups.Conclusions The MIM rat model can reflect the development of inflammatory and blood coagulation disorders and their relationship during the course of sepsis,and may thus provide a good foundation for further research into the disease course of sepsis.

BACKGROUND:Studies have shown that vision recovery with thinner grafts is faster and the risk of rejection is lower.In China,there is a lack of clinical efficacy analysis of different graftthicknesses after endothelial transplantation.Therefore,determining the optimal graftthickness is crucial for improving surgical efficacy. OBJECTIVE:To evaluate the effects of different graftthickness on vision recovery and other prognostic indexes after simple Descemet's stripping endothelial keratoplasty. METHODS:A total of 72 patients(72 eyes)with corneal endothelial decompensation who received simple Descemet's stripping endothelial keratoplasty at the General Hospital of Northern Theater Command from January 2013 to February 2023 were selected.There were 32 cases(32 eyes)in the thin graftgroup(＜100 μm)and 40 cases(40 eyes)in the thick graftgroup(≥100 μm).The best corrected visual acuity,corneal endothelial cell count,corneal graft transparency,postoperative complications and graftsurvival were observed in both groups before and 1,3,6,and 12 months after surgery. RESULTS AND CONCLUSION:The visual acuity after surgery was significantly improved in both groups,and the best corrected visual acuity 3 months after surgery in the thin graftgroup was better than that in the thick graftgroup(P＜0.05).There was no significant difference in the number of corneal endothelial cells and grafttransparency between the two groups 1 year after surgery(P＞0.05).There was no significant difference in the incidence of postoperative complications such as secondary glaucoma,graftimmune rejection and graftdisplacement between the two groups(P＞0.05).There was no significant difference in the 1-year survival rate of grafts between the two groups(93.8%vs.92.3%,P＞0.05).To conclude,simple Descemet's stripping endothelial keratoplasty is a safe and effective surgical method for corneal endothelial transplantation,and its postoperative efficacy is similar to that of traditional Descemet's stripping endothelial keratoplasty,and the graftimplantation method is simpler.Thinner grafts can provide optimal corrected vision earlier and complete corneal remodeling sooner.Therefore,in the treatment of corneal endothelial decompensation,thinner grafts are preferred to improve recovery time.

Objective:To observe and evaluate the clinical efficacy and safety of albumin-bound paclitaxel as first-line treatment for patients with advanced pancreatic cancer in China, and to explore the prognosis-related molecules in pancreatic cancer based on next-generation sequencing (NGS) of tumor tissues.Methods:From December 2018 to December 2020, patients with locally advanced or metastatic pancreatic cancer were recruited to accept albumin-bound paclitaxel as first-line treatment in the oncology departments of 24 hospitals in East China. The primary endpoints were overall survival (OS) and treatment related adverse events, and the secondary endpoint was progression-free survival (PFS). Adverse effects were graded using Common Terminology Criteria for Adverse Events 5.0 (CTCAE 5.0). NGS sequencing on the primary or metastatic tissue samples of pancreatic cancer obtained through surgical resection or biopsy was performed.Results:This study recruited 229 patients, including 70 patients with locally advanced pancreatic cancer (LAPC) and 159 patients with metastatic pancreatic cancer (mPC). The disease control rate was 79.9% and the objective response rate is 36.3%.The common adverse effects during treatment were anaemia (159 cases), leucopenia (170 cases), neutropenia (169 cases), increased aminotransferases (110 cases), and thrombocytopenia (95 cases), and the incidence of grade 3-4 neutropenia is 12.2% (28/229). The median follow-up time was 21.2 months (95% CI: 18.5-23.1 months). The median PFS (mPFS) was 5.3 months (95% CI: 4.37-4.07 months) and the median OS (mOS) was 11.2 months (95% CI: 9.5-12.9 months). The mPFS of patients with LAPC was 7.4 months (95% CI: 6.6-11.2 months), and their mOS was 15.5 months (95% CI: 12.6-NA months). The mPFS of patients with mPC was 3.9 months (95% CI: 3.4-5.1 months), and their mOS was 9.3 months (95% CI: 8.0-10.8 months). Multivariate Cox regression analysis showed that clinical stage ( HR=1.47, 95% CI: 1.06-2.04), primary tumor site ( HR=0.64, 95% CI: 0.48-0.86), Eastern Cooperative Oncology Group Performance Status (ECOG PS) score ( HR=2.66, 95% CI: 1.53-4.65), and whether to combine radiotherapy ( HR=0.65, 95% CI: 0.42-1.00) were independent influencing factors for the PFS of these patients. The primary tumor site ( HR=0.68, 95% CI: 0.48-0.95), ECOG score ( HR=5.82, 95% CI: 3.14-10.82), and whether to combine radiotherapy ( HR=0.58, 95% CI: 0.35-0.96) were independent influencing factors of the OS of these patients. The most frequent gene mutations in these advanced stage pancreatic patients were KRAS (89.66%), TP53 (77.01%), CDKN2A (32.18%), and SMAD4 (21.84%) by NGS of tumor tissues from 87 pancreatic cancer patients with sufficient specimens. Further analysis revealed that mutations in CDKN2B, PTEN, FGF6, and RBBP8 genes were significantly associated with an increased risk of death ( P＜0.05). Conclusion:Albumin-bound paclitaxel as first-line treatment demonstrated feasible anti-tumor efficacy and manageable safety for patients with advanced pancreatic cancer in China.

Inflammation-driven endothelial dysfunction is the major initiating factor in atherosclerosis, while the underlying mechanism remains elusive. Here, we report that the non-canonical stimulator of interferon genes (STING)-PKR-like ER kinase (PERK) pathway was significantly activated in both human and mice atherosclerotic arteries. Typically, STING activation leads to the activation of interferon regulatory factor 3 (IRF3) and nuclear factor-kappa B (NF-κB)/p65, thereby facilitating IFN signals and inflammation. In contrast, our study reveals the activated non-canonical STING-PERK pathway increases scaffold protein bromodomain protein 4 (BRD4) expression, which encourages the formation of super-enhancers on the proximal promoter regions of the proinflammatory cytokines, thereby enabling the transactivation of these cytokines by integrating activated IRF3 and NF-κB via a condensation process. Endothelium-specific STING and BRD4 deficiency significantly decreased the plaque area and inflammation. Mechanistically, this pathway is triggered by leaked mitochondrial DNA (mtDNA) via mitochondrial permeability transition pore (mPTP), formed by voltage-dependent anion channel 1 (VDAC1) oligomer interaction with oxidized mtDNA upon cholesterol oxidation stimulation. Especially, compared to macrophages, endothelial STING activation plays a more pronounced role in atherosclerosis. We propose a non-canonical STING-PERK pathway-dependent epigenetic paradigm in atherosclerosis that integrates IRF3, NF-κB and BRD4 in inflammatory responses, which provides emerging therapeutic modalities for vascular endothelial dysfunction.
