Objective To demonstrate the visual results and complications of an cryopexy in combination with intravitreal injection of expending gas in the therapy of primary rhegmatogenous retinaldetachment (RRD). Methods Thirty-two cases (32 eyes) were retrospectively reviewed in this study. The RRD diagnosis was confirmed by best corrected visual acuity,slit-lamp microscope,indirected ophthalmoscope and Goldman three-mirror contact lens. All patients had undergone cryopexy with intravitreal gas injection and assisted by correct body position. Patients were followed for 6 to 24 months. Post-operative BCVA,final anatomical outcome, complications and failed cases were analyzed. Results The reattachment rate of cryopexy with intravitreal gas injection was 81%(26/32 eyes). Four eyes required additional scleral buckling. Two eyes needed additional vitrectomy with intravitreal injection of expending gas (SF6).Final retinal reattachment was achieved in all 32 subjects (100%). Postoperative BCVA was significantly improved (P < 0.01). Conclusion Cryopexy with intravitreal gas injection is a simple,less trauma, lower cost and effective surgery for primary rhegmatogenous retinaldetachment.

Objective To evaluate the clinical efficacy and safety of domestic Sirolimus-eluting stents (Firebird) and imported Zotalimus-eluting stents ( Resolute) in the treatment of patients with unprotected left main coronary artery disease ( ULMCA) . Methods We retrospectively enrolled 76 patients with ULMCA treated by percutaneous coronary intervention (PCI) under the guidance of IVUS in our hospital. According to the different stents used in the procedure, the patients were divided into two groups: Domestic Sirolimus-Eluting Stents group (Firebird group, n = 42) and Imported Zotarolimus-Eluting Stents group (Resolute group, n = 34) . We analyzed the baseline characteristics, coronary artery lesion characteristics, stenting strategies and any changes in left ventricular ejection fraction ( LVEF) in both groups and investigated the long-term clinical outcomes. Results There were no significant differences in the baseline characteristics, the SYNTAX scores of the coronary artery lesion and the rate of complete revascularization between the two groups. Compared with that in Firebird group, there were more cases involving the distal left main (79. 4% vs. 45. 2% , P ﹤ 0. 05) and more patients using two stents strategies (29. 4% vs. 7. 1% , P ﹤ 0. 05) in the Resolute group. The change in LVEF post-PCI had no difference between the two groups. The patients were followed up for a mean of (23. 3 ± 10. 7) months. During the follow-up period, the occurrence of MACCE had no significant difference between the two groups. In the Firebird group, there were one sudden cardiac death, one nonfatal myocardial infarction, one stroke and five patients with recurrence of angina pectoris. In the Resolute group there were one sudden cardiac death, one target lesion revascularization and four patients with recurrence of angina pectoris. Conclusions Compared with the imported Zotalimus-Eluting Stents, the domestic Sirolimus-Eluting Stents are safe and effective in the treatment of patients with unprotected left main lesions under the guidance of IVUS. The two kinds of stent showed similar long-term clinical outcomes.

Objective:To study the relationship between pregnancy outcomes and blood glucose index at different time points in 75 g oral glucose tolerance test (OGTT).Methods:A total of 403 pregnant women who receiveda 75 g OGTT were enrolled.Pregnant women were divided into three groups:group A with one abnormal blood glucose level (group A1:abnormal fasting glucose level;group A2:abnomal 1 hour glucose level;group A3:abnormal 2 hour glucose level), group B with two abnormal blood glucose level (group B1:abnormal fasting and 1 hour glucose level;group B2:abnormal fasting and 2 hours glucose level;group B3:abnormal 1 hour and 2 hours glucose level), and group C with abnormal blood glucose level in all three time points.Retrospective analysis of general information and pregnancy outcomes of pregnant women.Results:There were significant differences in A, B and C groups when comparing the incidence of hypothyroidism, hypertensive disorders of pregnancy, cesarean section rate, neonatal body mass index (BMI), chest circumference, macrosomia preterm birth and transfer to Neonatal Intensive Care Unit (P<0.05), and the incidence of adverse outcomes in group C was higher than that in group A and B.The neonatal body mass index, chest circumference and fetal distress rate and cesarean section rate in the A2 group were significantly higher than those in the A1 and A3 groups (P<0.05).The incidence of macrosomia and cesarean section in group B3 was lower than that in group B1 and B2 (P<0.05).Conclusions:The maternal and neonatal adverse outcomes would increase if the abnormal glucose level was detected in all three time points in 75 g OGTT.When the fasting and 1 or 2 hour blood glucose level were abnormal, the incidence of neonatal macrosomia would increase.There could be a correlation between 1 hour blood glucose level and neonatal body mass index.

Immunogenic cell death (ICD) plays a major role in cancer immunotherapy by stimulating specific T cell responses and restoring the antitumor immune system. However, effective type II ICD inducers without biotoxicity are still very limited. Herein, a tentative drug- or photosensitizer-free strategy was developed by employing enzymatic self-assembly of the peptide F-pY-T to induce mitochondrial oxidative stress in cancer cells. Upon dephosphorylation catalyzed by alkaline phosphatase overexpressed on cancer cells, the peptide F-pY-T self-assembled to form nanoparticles, which were subsequently internalized. These affected the morphology of mitochondria and induced serious reactive oxygen species production, causing the ICD characterized by the release of danger-associated molecular patterns (DAMPs). DAMPs enhanced specific immune responses by promoting the maturation of DCs and the intratumoral infiltration of tumor-specific T cells to eradicate tumor cells. The dramatic immunotherapeutic capacity could be enhanced further by combination therapy of F-pY-T and anti-PD-L1 agents without visible biotoxicity in the main organs. Thus, our results revealed an alternative strategy to induce efficient ICD by physically promoting mitochondrial oxidative stress.
