To evaluate the efficacy and safety of upadacitinib in the treatment of moderate-to-severe atopic dermatitis (AD), and provide reference for rational clinical medication. PubMed, Medline, Embase, Web of Science, Clinical Trials Website, and Cochrane Library databases were searched from the time of establishment until January 6, 2024, to compile a list of all randomized controlled trials (RCTs) including upadacitinib in the treatment of moderate-to-severe AD. The quality of the included studies was evaluated using the Cochrane Systematic Review. Review Manager 5.3 software was utilized for statistical analysis of outcome measures. A total of five studies were included in the meta-analysis. The results revealed that the 15 mg and 30 mg upadacitinib significantly improved Eczema Area and Severity Index (EASI) 75% {[Odds Ratio (OR) = 8.58, 95% confidence interval (CI) (5.84-12.60), P < 0.00001] [OR = 15.62, 95% CI (10.89-22.42), P < 0.00001]}, Numerical Rating Scale (NRS) ≥ 4 {[OR = 7.13, 95% CI (5.63-9.01), P < 0.00001] [OR = 11.30, 95% CI (8.93-14.31), P < 0.00001]}, and Investigator's Global Assessment (IGA) 0/1 {[OR = 8.63, 95% CI (6.60-11.27), P < 0.00001] [OR = 16.04, 95% CI (12.26-20.99), P < 0.00001]} compared to placebo. In terms of safety, although 15 mg and 30 mg upadacitinib significantly increased the overall adverse events rate compared to placebo {[OR = 1.31, 95% CI (1.09-1.58), P = 0.004] [OR = 1.85, 95% CI (1.54-2.21), P < 0.00001]}, there was no significant difference in the serious adverse events rate {[OR = 0.73, 95% CI (0.41-1.29), P = 0.28] [OR = 0.69, 95% CI (0.39-1.23), P = 0.21]} and withdrawal rate due to adverse events {[OR = 0.66, 95% CI (0.39-1.11), P = 0.12] [OR = 0.85, 95% CI (0.52-1.38), P = 0.50]} compared to placebo. This meta-analysis preliminarily suggests that upadacitinib is effective and safe for usage in the treatment of moderate-to-severe AD. Additionally, upadacitinib can instantly relieve itchiness and effectively reduce symptoms and signs, with its 30-mg dose being more effective than the 15-mg dose.

Background： Pulmonary embolism （PE） can be difficult to diagnose in elderly patients because of the coexistent diseases and the combination of drugs that they have taken. We aimed to compare the clinical diagnostic values of the Wells score, the revised Geneva score and each of them combined with D-dimer for suspected PE in elderly patients. Methods： Three hundred and thirty-six patients who were admitted for suspected PE were enrolled retrospectively and divided into two groups based on age （≥65 or 〈65 years old）. The Wells and revised Geneva scores were applied to evaluate the clinical probability of PE, and the positive predictive values of both scores were calculated using computed tomography pulmonary arteriography as a gold standard： overall accuracy was evaluated by the area under the curve （AUC） of receiver operator characteristic curve： the negative predictive values of D-dimcr, the Wells score combined with D-dimer, and the revised Geneva score combined with D-dimer were calculated. Results： Ninety-six cases （28.6%） were definitely diagnosed as PE among 336 cases, among them 56 cases （58.3%） were 〉65 years old. The positive predictive values of Wells and revised Geneva scores were 65.8% and 32.4%, respectively （P 〈 0.05） in the elderly patients; the AUC for the Wells score and the revised Geneva score in elderly was 0.682 （95% confidence interval [CI] ： 0.612- 0.746） and 0.655 （95% CI： 0.584-0.722）, respectively （P = 0.389）. The negative predictive values of D-dimer. the Wells score combined with D-dimer, and the revised Geneva score combined with D-dimer were 93.7%, 100%, and 100% in the elderly, respectively. Conclusions： The diagnostic value of the Wells score was higher than the revised Geneva score for the elderly cases with suspected PE. The combination of either the Wells score or the revised Geneva score with a normal D-dimer concentration is a sate strategy to rule out PE.

Background： The antibiotic meropenem is commonly administered pharmacokinetic, clinical, and bacteriological efficacies of continuous patients. n patients with severe sepsis and septic shock. We compared the infusion of meropenem versus internaittent administration in such Methods： Patients admitted to the Intensive Care Unit （ICU） with severe sepsis or septic shock who received meropenem were randomly assigned to either the continuous （n = 25） or intermittent groups 01 = 25）. The continuous group received a loading dose of 0.5 g of meropenem lbllowed by a continuous infusion of 3 g/day： the intermittent group received an initial dose of 1.5 g lbllowed by 1 g lbr every 8 h. Clinical success, microbiological eradication, superinfection, ICU mortality, length of ICU stay, and duration of meropenem treatment were assessed. Serial plasma meropenem concentrations tbr the first and third dosing periods （steady state） were also measured. Results： Clinical success was similar in both the continuous （64%） and intermittent （56%） groups （P = 0.564）： the rates of microbiological eradication and superinfection （81.8% vs. 66.7% [P = 0.255] and 4% vs. 16% [P 0.157], respectively） showed improvement in the continuous group. The duration of meropenem treatment was significantly shorter in the continuous group （7.6 vs. 9.4 days; P = 0.035）, where a better steady-state concentration was also achieved. Peak and trough concentrations were significantly different between the continuous and intermittent groups both in the first （Cmax： 19.8 mg/L vs. 51.8 mg/L, P = 0.000; Cmin： 11.2 mg/L vs. 0.5 nag/L, P = 0.000） and third dosing periods （Cmax： 12.5 mg/L vs. 46.4 rag/L, P = 0.000; Cmin： 11.4 mg/L vs. 0.6 rag/L, P = 0.000）. For medium-susceptibility pathogens, continuous inthsion concentrations above the minimal inhibitory concentration were 100%, which was better than that in the intermittent group- Conclusions： Continuous infusion of meropenem provides significantly shorter treatment duration and a tendency for superior bacteriological efficacy than intermittent administration. Continuous inthsion may be more optimal against imermediate-susceptibility pathogens.

MicroRNAs （miRNAs） are short, endogenously expressed RNAs （-21-22 nt） processed from stem-loop regions of longer RNA precursors by a Dicer-like enzyme （Jones- Rhoades et al., 2006）. In plants, microRNAs play an essential role in regulating many fundamental molecular in- teractions, including plant growth, development and re- sponse to environmental stress （Rogers and Chen, 2013）. In comparison with the roles of microRNAs in animals, bio- genesis and function of microRNAs in plants appears to be drastically different （Llave et al., 2002; Zhang et al., 2007）.

Of the two cultivated species of allopolyploid cotton, Gossypium barbadense produces extra-long fibers for the production of superior textiles. We sequenced its genome (AD) 2 and performed a comparative analysis. We identified three bursts of retrotransposons from 20 million years ago (Mya) and a genome-wide uneven pseudogenization peak at 11–20 Mya, which likely contributed to genomic divergences. Among the 2,483 genes preferentially expressed in fiber, a cell elongation regulator, PRE1 , is strikingly A t biased and fiber specific, echoing the A-genome origin of spinnable fiber. The expansion of the PRE members implies a genetic factor that underlies fiber elongation. Mature cotton fiber consists of nearly pure cellulose. G. barbadense and G. hirsutum contain 29 and 30 cellulose synthase (CesA) genes, respectively; whereas most of these genes (>25) are expressed in fiber, genes for secondary cell wall biosynthesis exhibited a delayed and higher degree of up-regulation in G. barbadense compared with G. hirsutum , conferring an extended elongation stage and highly active secondary wall deposition during extra-long fiber development. The rapid diversification of sesquiterpene synthase genes in the gossypol pathway exemplifies the chemical diversity of lineage-specific secondary metabolites. The G. barbadense genome advances our understanding of allopolyploidy, which will help improve cotton fiber quality.

Chronic pain is highly prevalent worldwide and severely affects daily lives of patients and family members. Praeruptorin C (Pra-C) is a main active ingredient derived from Peucedanum praeruptorum Dunn, traditionally used as antibechic, anti-bronchitis and anti-hypertension drug. Here, we evaluated the effects of Pra-C in a chronic inflammatory pain mouse model induced by complete Freund’s adjuvant (CFA) injection. Pra-C (3 mg/kg) treatment for just 3 days after CFA challenge relieved CFA-induced mechanical allodynia and hindpaw edema in mice. In the anterior cingulate cortex (ACC), Pra-C treatment inhibited microglia activation and reduced levels of proinflammatory cytokines, TNF-α and IL-1β, and suppressed upregulation of glutamate receptors caused by CFA injection. In addition, Pra-C attenuated neuronal hyperexcitability in ACC of CFA-injected mice. In vitro studies confirmed the analgesic effect of Pra-C was due to its inhibitory ability on microglial activation. In conclusion, Pra-C administration had a certain effect on relieving chronic pain by inhibiting microglial activation, attenuating proinflammatory cytokine releasing and regulating excitatory synaptic proteins in the ACC of the CFA-injected mice.

The transient receptor potential vanilloid 1 (TRPV1) is a non-selective cation channel that is activated by capsaicin (CAP), the main component of chili pepper. Despite studies in several neurological diseases, the role of TRPV1 in demyelinating diseases remains unknown. Herein, we reported that TRPV1 expression was increased within the corpus callosum during demyelination in a cuprizone (CPZ)-induced demyelination mouse model. TRPV1 deficiency exacerbated motor coordinative dysfunction and demyelination in CPZ-treated mice, whereas the TRPV1 agonist CAP improved the behavioral performance and facilitated remyelination. TRPV1 was predominantly expressed in Iba1 + microglia/macrophages in human brain sections of multiple sclerosis patients and mouse corpus callosum under demyelinating conditions. TRPV1 deficiency decreased microglial recruitment to the corpus callosum, with an associated increase in the accumulation of myelin debris. Conversely, the activation of TRPV1 by CAP enhanced the recruitment of microglia to the corpus callosum and potentiated myelin debris clearance. Using real-time live imaging we confirmed an increased phagocytic function of microglia following CAP treatment. In addition, the expression of the scavenger receptor CD36 was increased, and that of the glycolysis regulators Hif1a and Hk2 was decreased. We conclude that TRPV1 is an important regulator of microglial function in the context of demyelination and may serve as a promising therapeutic target for demyelinating diseases such as multiple sclerosis.
