Case report of rapidly progressive proliferative verrucous leukoplakia and a proposal for aetiology in mainland China
Proliferative verrucous leukoplakia (PVL) is a rare oral leukoplakia and has four features such as chronic proliferation, multiple occurrences, refractoriness to treatment and high rate of malignant transformation. As mentioned above, most PVL cases processed to malignancy over many years, sometimes 20 years. However, this report described a case of rapid progress, which had malignant transformation in a short period. Additionally, the aetiology of PVL was discussed and immunity was proposed as the possible cause
Improving Code Generation by Dynamic Temperature Sampling
Recently, Large Language Models (LLMs) have shown impressive results in code
generation. However, existing decoding strategies are designed for Natural
Language (NL) generation, overlooking the differences between NL and
programming languages (PL). Due to this oversight, a better decoding strategy
for code generation remains an open question. In this paper, we conduct the
first systematic study to explore a decoding strategy specialized in code
generation. With an analysis of loss distributions of code tokens, we find that
code tokens can be divided into two categories: challenging tokens that are
difficult to predict and confident tokens that can be easily inferred. Among
them, the challenging tokens mainly appear at the beginning of a code block.
Inspired by the above findings, we propose a simple yet effective method:
Adaptive Temperature (AdapT) sampling, which dynamically adjusts the
temperature coefficient when decoding different tokens. We apply a larger
temperature when sampling for challenging tokens, allowing LLMs to explore
diverse choices. We employ a smaller temperature for confident tokens avoiding
the influence of tail randomness noises. We apply AdapT sampling to LLMs with
different sizes and conduct evaluations on two popular datasets. Results show
that AdapT sampling significantly outperforms state-of-the-art decoding
strategy
Preparation of total flavonoids from loquat flower and its protective effect on acute alcohol-induced liver injury in mice
AbstractThis study aimed to research the preparation techniques of total flavones from loquat flower (TFLF), its anti-oxidation capacity, and its protective effect on hepatic injury. The best extraction parameters by orthogonal experimentation were water at 100°C, extraction time 2.5 hours, solid/liquid ratio 1:20, and three decoctions. The chromogenic reaction to the flavones showed that loquat flowers mainly contained flavone, flavonol, and flavanone compounds combining ortho-phenolic hydroxyl group structure in the 10–30% ethanol fraction. The anti-oxidant capacity of O2−· was 26.09% and of OH−·was 83.01% by salicylic acid and pyrogallol auto-oxidation. Compared with the model group, TFLF lowered the levels of alanine aminotransferase, aspartate aminotransferase, triglyceride, and malondialdehyde and liver index significantly, and upregulated the expression of adipose triglyceride lipase and Heine oxygenase-1 mRNA. The present findings suggest that TFLF has protective effect on acute alcoholinduced liver injury in mice and may be related to its antioxidant and free-radical scavenging activity

Development and characterization of a core set of SSR markers for fingerprinting analysis of Chinese maize varieties
A core set of 60 SSRs was selected and modified using 231 Chinese and USA maize (Zea mays L.) inbred lines
from more than 2000 SSRs for DNA fingerprinting analysis. All 60 SSR markers met the following criteria: (1) amplification
of a single locus; (2) distinct amplification products; (3) adequate intervals between adjacent alleles; (4)
suitable PCR fragment size; (5) reasonable discrimination power (DP); and (6) even distribution across the maize
genome. Furthermore, the 60 SSR primers were re-designed to adjust the PCR product size. Together with the
application of four different fluorescent dyes, a high-throughput 10-plex capillary electrophoresis platform was
explored. The 60 core SSR markers were further divided into three groups (20 SSRs per group) according to
peak morphology and DP value. Groups I, II and III were used in DNA fingerprinting analysis as a basic core, an
expanded core and a candidate core set respectively. The allele number per locus varied from three to 22 with an
average of 8.95; the average number of alleles per group I, II and III was a respective 7.35, 7.8 and 11.4. The DP
values ranged from 0.366 to 0.913, with an average of 0.718 among all loci; the average group DP values were
0.697, 0.718 and 0.737 for groups I, II and III respectively; and the cumulative values of discrimination power (CDP)
approached 1 for all groups. Cluster analysis results using 60 selected loci divided the Chinese inbred lines into six
groups, including Luda Red Cob, P, Improved Reid, Tang-si-ping-tou, Waxy and Lancaster. The USA inbred lines
were segregated into four groups, including SSS, Lancaster, Iodent and Oh43/Oh07Mid mixed
Three-dimensional in vivo evaluation of the cornea in patients with unilateral posterior interstitial keratitis
PurposeThe purpose of this study was to investigate the in vivo morphologic features of the cornea in patients with unilateral posterior interstitial keratitis.MethodsSeven eyes of 7 patients with unilateral posterior interstitial keratitis were examined by slit-lamp biomicroscopy, anterior segment optical coherence tomography (AS-OCT), and in vivo confocal microscopy (IVCM). The imaging features of the cornea were evaluated and analyzed.ResultsBy slit-lamp examination, the posterior corneal stromal opacities were observed in all 7 eyes, and deep neovascularization in 4 eyes. The posterior stromal opacities showed higher reflectivity with an intact overlying epithelium by AS-OCT and did not invade the Bowman’s layer in all cases. IVCM revealed highly reflective dispersed microdots, needle-shaped bodies, and increased reflectivity of keratocytes in the lesion site in all patients. Active Langerhans cells and an attenuated subbasal nerve plexus were observed in 5 eyes. After treatment, the active Langerhans cells disappeared; however, highly reflective microdots and needle-shaped bodies remained.ConclusionThe three-dimensional evaluation of slit-lamp biomicroscopy, AS-OCT, and IVCM may help in the early diagnosis of patients with posterior interstitial keratitis
