The Ly-6 and uPAR (LU) domain-containing proteins represent a large family of cell-surface markers. In particular, mouse Ly-6A/Sca-1 is a widely used marker for various stem cells; however, its human ortholog is missing. In this study, based on a systematic survey and comparative genomic study of mouse and human LU domain-containing proteins, we identified a previously unannotated human gene encoding the candidate ortholog of mouse Ly-6A/Sca-1. This gene, hereby named LY6A, reversely overlaps with a lncRNA gene in the majority of exonic sequences. We found that LY6A is aberrantly expressed in pituitary tumors, but not in normal pituitary tissues, and may contribute to tumorigenesis. Similar to mouse Ly-6A/Sca-1, human LY6A is also upregulated by interferon, suggesting a conserved transcriptional regulatory mechanism between humans and mice. We cloned the full-length LY6A cDNA, whose encoded protein sequence, domain architecture, and exon-intron structures are all well conserved with mouse Ly-6A/Sca-1. Ectopic expression of the LY6A protein in cells demonstrates that it acts the same as mouse Ly-6A/Sca-1 in their processing and glycosylphosphatidylinositol anchoring to the cell membrane. Collectively, these studies unveil a novel human gene encoding a candidate biomarker and provide an interesting model gene for studying gene regulatory and evolutionary mechanisms.

BACKGROUND: This study aimed to determine the reasons for conversion and elucidate the safety and efficacy of transition to tenofovir alafenamide/emtricitabine/bictegravir sodium (TAF/FTC/BIC) in highly active antiretroviral therapy (HAART)-experienced HIV-infected patients in real-world settings. METHODS: We conducted a retrospective cohort study. The treatment conversion rationales, safety, and effectiveness in 1684 HIV-infected patients with previous HAART experience who switched to TAF/FTC/BIC were evaluated at Beijing Ditan Hospital from September 2021 to Auguest 2022. RESULTS: Regimen simplification (990/1684, 58.79%) was the most common reason for switching, followed by osteoporosis or osteopenia (375/1684, 22.27%), liver dysfunction (231/1684, 13.72%), decline in tenofovir alafenamide/emtricitabine/elvitegravir/cobicistat (TAF/FTC/EVG/c) with food restriction (215/1684, 12.77%), virological failure (116/1684, 6.89%), and renal dysfunction (90/1684, 5.34%). In patients receiving non-nucleotide reverse transcriptase inhibitors (NNRTI)-containing regimens, lipid panel changes 1 year after switching indicated a difference of 3.27 ± 1.10 mmol/L vs . 3.40 ± 1.59 mmol/L in triglyceride ( P  = 0.014), 4.82 ± 0.74 mmol/L vs . 4.88 ± 0.72 mmol/L in total cholesterol ( P  = 0.038), 3.09 ± 0.70 mmol/L vs . 3.18 ± 0.66 mmol/L in low-density lipoprotein ( P  <0.001), and 0.99 ± 0.11 mmol/L vs . 0.95 ± 0.10 mmol/L in high-density lipoprotein ( P  <0.001). Conversely, among patients receiving booster-containing regimens, including TAF/FTC/EVG/c and lopinavir/ritonavir (LPV/r), lipid panel changes presented decreased trends. We also observed an improved trend in viral load suppression, and alanine transaminase (ALT), aspartate transaminase (AST), estimated glomerular filtration rate (eGFR), and serum creatinine levels after the transition ( P  <0.001). CONCLUSION The transition to TAF/FTC/BIC demonstrated good treatment potency. Furthermore, this study elucidates the motivations behind the adoption of TAF/FTC/BIC in real-world scenarios, providing clinical evidence supporting the stable conversion to TAF/FTC/BIC for HAART-experienced patients.

The difference of integrals of TCM syndrome between the two groups showed statistical significance (P<0.05) on day 14.ConclusionHejie Fenxiao Decoction combined with basic regular Western medicine can better improve the clinical symptom, recover the renal function, and decrease the rate of renal replacement and death of AKI damp-heat patients.

Contracture and spasticity of ankle joints were major sources of disability in neurological impairment including stroke and cerebral palsy, etc. The manual stretching used in physical therapy might be laborious and time-consuming to the therapists and the outcome was dependent on the experience and the subjectiveend feelingof the therapists. A device was developed that could safely stretch the an-kle joint to its extreme positions with quantitative control of the resistance torque and stretching velocity. Furthermore, it could satisfy a strong need for quantitative and objective measures of the impairment and rehabilitation outcome. This was just the meaning intelligent stretching referred to. This article described the origin of the concept of intelligent stretching and its definition, operational principle, and su-periority and weakness, as well as its application in ankle joint spasticity and contracture in patients with stroke and cerebral palsy.

Objective To observe the effect of Weipixiao, a compound recipe which has the actions of strengthening spleen, resolving stasis and removing toxins, on the histopathological changes of gastric mucosal tissue in rats with gastric precancerous lesions ( GPL) . Methods SD rats were randomly divided into normal group, model group, Vitacoenzyme group (0.2 g·kg-1·d-1), and high-, middle-, and low-dose Weipixiao groups ( in the dose of 15, 7.5, 3.75 g·kg-1·d-1, respectively) . Except for the normal control group, the rats in other groups received spontaneous intake of N-methyl-N’-nitro-nitrosoguanidine ( MNNG) solution combined with irregular diet and oral use of purgative herbs for 18 weeks to induce GPL. From the 9th week, the mediation groups were simultaneously given corresponding medicine for 10 weeks. At the end of the experiment, the histopathological changes of gastric mucosal tissue in all groups were observed. Results Pathological scores of intestinal metaplasia and epithelial dysplasia in rat gastric mucosa of the model group were significantly increased ( P<0.01 compared with those of the normal group) , but were decreased in three Weipixiao groups to various degrees, particularly in low-dose Weipixiao group ( P<0.05 or P<0.01) . Conclusion Weipixiao can block and reverse gastric intestinal metaplasia and dysplasia in GPL rats to certain degrees, and low-dose Weipixiao may have better long-term effect for the prevention and treatment of GPL.

OBJECTIVETo establish a one-step four multiplex reverse transcription polymerase chain reaction (RT-PCR) method based on Homo-Tag Assisted Non-Dimer System (HAND) system for simultaneous detection of 4 diarrhea viruses of rotavirus, astrovirus, norovirus and sapovirus.
