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.

Objcetive To investigate the relationship between blood β-hydroxybutyric acid and urine ketone in the di-agnosis of diabetic ketosis (DK). Methods Peripheral blood β-hydroxybutyric acid and urine ketone were detected when the peripheral blood glucose was more than 13.9 mmol/L in patients with diabetes. Results (1) In 81 diabetes pa-tients with blood glucose more than 13.9 mmol/L, the incidence of DK was 13.58% and the incidence of diabetic ke-toacidosis (DKA) was 9.88%. (2) The peripheral blood glucose was positively correlated with β-hydroxybutyric acid (r=0.330, P=0.003), but it was not correlated with urine ketone. (3) The peripheral blood β-hydroxybutyric acid was posi-tively correlated with urine ketone (r=0.516, P=0.000). (4) In patients with DK or DKA, 5.26%(1/19) of those were with urine ketone(-) or (+-), whereas 36.84% (7/19) of those were with blood β-hydroxybutyric acid less than 1 mmol/L. (5) When urine ketone was used as the reference test for diagnosis of DK, the optimal value of blood β-hydroxybutyric acid was 0.35 mmol/L. Conclusion For missed diagnosis of DK may be happend if blood β-hydroxybutyric acid or urine ketone is used alone, the co-monitoring of blood β-hydroxybutyric acid and urine ketone can reduce the inci-dence of missed diagnosis of DK. The urine ketosis may have existed when the blood β-hydroxybutyric acid is slightly elevated (≥0.35 mmol/L). In the situation, the urine ketone should be tested in order to avoid missed diagnosis of DK.

Objective:To detect the expression level of RAB39B gene and the effect of RAB39B on autophagy and α-synuclein, and then investigate the role of RAB39B gene mutation c.536dupA in the pathogenesis of Parkinson′s disease.Methods:Based on the novel RAB39B gene c.536 dupamutation identified in the previous work, the recombinant expression plasmid (pcDNA3.1-HA-RAB39B-536) of RAB39B gene with this mutation and wild-type recombinant expression plasmid (pcDNA3.1-HA-RAB39B) of RAB39B gene were constructed, and the recombinant expression plasmid was transfected into N2a cells with liposome as experimental group. The control group was made up with N2a cells transfected with plasmid pcDNA3.1-HA-RAB39B. Real-time polymerase chain reaction, Western blotting, immunofluorescence and immunoprecipitation techniques were used to detect the expression level of mutant RAB39B gene and the effects of RAB39B on autophagy and α-synuclein.Results:In the N2a cell model, the transcription level of mutant RAB39B was about twice that of wild type RAB39B, while the protein level of mutant RAB39B (0.30±0.00) was significantly lower than that of wild type (1.50±0.25, t=8.313, P<0.05). After adding proteasome inhibitor MG132, the protein level of mutant RAB39B increased (0.70±0.10, t=6.925, P<0.05); the level of microtubule-associated protein 1 light chain 3 BⅡ/Ⅰ of mutant RAB39B (3.11±0.30) was significantly lower than that of wild type (7.03±0.20, t=18.831, P<0.05); overexpression of wild type and mutant RAB39B did not affect the level of endogenous α-synuclein; overexpression of wild-type RAB39B resulted in elevated level of exogenous wild-type (p.A53T; from 0.60±0.11 to 1.25±0.08, t=8.254, P<0.05) and mutant (from 0.55±0.08 to 1.15±0.08, t=9.293, P<0.05) α-synuclein. Conclusions:The stability of the RAB39B protein decreased with the appearance of c.536 dupA mutation, the mutant protein may be degraded through the ubiquitin-proteasome pathway, and this mutation may affect the autophagy level of cells. RAB39B protein may interact with α-synuclein in vivo and may be involved in the maintenance of the stable level of α-synuclein.

Alzheimer's disease (AD) is associated with the impairment of white matter (WM) tracts. The current study aimed to verify the utility of WM as the neuroimaging marker of AD with multisite diffusion tensor imaging datasets [321 patients with AD, 265 patients with mild cognitive impairment (MCI), 279 normal controls (NC)], a unified pipeline, and independent site cross-validation. Automated fiber quantification was used to extract diffusion profiles along tracts. Random-effects meta-analyses showed a reproducible degeneration pattern in which fractional anisotropy significantly decreased in the AD and MCI groups compared with NC. Machine learning models using tract-based features showed good generalizability among independent site cross-validation. The diffusion metrics of the altered regions and the AD probability predicted by the models were highly correlated with cognitive ability in the AD and MCI groups. We highlighted the reproducibility and generalizability of the degeneration pattern of WM tracts in AD.

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.
