Anterior ischemic optic neuropathy (AION) is the ciliary artery-circulatory disorders for the supply of optic nerve head area before the sieve plate prozone and sieve plate district, result in the insufficient blood supply of the optic nerve head and ischemia hypoxia, edema. Clinical manifestations of the type with non-artery inflammatory neuropathy and artery inflammatory neuropathy, which would both eventually lead to the irreversible damage to the optic nerve. In the early phase of AION, the main method is giving a glucocorticoids intravenous drip and a periglomerular injection (or retrobulbar injection) in time, but using the glucocorticoids for a long time or in quantity can cause a series of complications. Therefore, the combination of traditional Chinese and western medicine treatment of AION has become more and more significant in clinic.

Objective To discuss the diagnosis and laparoscopic treatment for superior mesenteric artery compressing syndrome (SMACS).Methods A retrospective analysis was conducted on 62 SMACS patients who had received total laparoscopy treatment from October 2006 to May 2016.Results All 62 cases received upper gastrointestinal series and definite diagnosis was achieved on 51 cases;Definite diagnosis was made on 31 cases among 44 cases undergoing CTA (CTA,CT angiography) examination,19 cases were diagnosed with the disease among 26 cases who had received ultrasound examination.Total laparoscopic duodenojejunostomy was conducted on 41 cases,total laparoscopic gastrointestinal anastomosis was conducted on 14 cases,total laparoscopic gastroduodenal double shortcut anastomosis was conducted on 7 cases.All patients were cured or alleviated and discharged from hospital.Conclusions Upper GI contrast series made definite diagnosis on most SMACS cases.For patients with relapsing symptoms and poor conservative treatment result a surgery is recommended.Total laparoscopic duodenojejunostomy is the mainstay of treatment and is safe and reliable.

The regulator of expression of virion(Rev)protein binds specifically to the Rev-responsive element(RRE)RNA in order to regulate the expression of the human immunodeficiency virus(HIV)-1 genes.Fluores-cence indicator displacement assays have been used to identify ligands that can inhibit the Rev-RRE interaction;however,the small fluorescence indicators cannot fully replace the Rev peptide or protein.As a result,a single rhodamine B labeled Rev(RB-Rev)model peptide was utilized in this study to develop a direct and efficient Rev-RRE inhibitor screening model.Due to photon-induced electron transfer quenching of the tryptophan residue on the RB fluorophore,the fluorescence of RB in Rev was weakened and could be dramatically reactivated by interaction with RRE RNA in ammonium acetate buffer(approximately six times).The interaction could reduce the electron transfer between tryptophan and RB,and RRE could also increase RB fluorescence.The inhibitor screening model was evaluated using three known positive Rev-RRE inhibitors,namely,proflavin,6-chloro-9-[3-(2-chloroethylamino)pro-pylamino]-2-methoxyacridine(ICR 191),and neomycin,as well as a negative drug,arginine.With the addition of the positive drugs,the fluorescence of the Rev-RRE decreased,indicating the displacement of RB-Rev.This was confirmed using atomic force microscopy(AFM)and the fluorescence was essentially unaffected by the addition of arginine.The results demonstrated that RB-Rev can be used as a fluorescent probe for recognizing small ligands that target RRE RNA.The Rev-RRE inhibitor screening model offers a novel approach to evaluating and identifying long-acting Rev inhibitors.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.
