916-0.976; P=0.000], while age and hsCRP were protective factors (HR =1.048, 95% CI 1.028-1.067, P=0.000; HR =1.049, 95% CI 1.024-1.075, P=0.000). The estimated median overall survival (OS) at early HD was 56.00 months in the low ALB group, 83.00 months in the moderate ABL group, and 95.00 months in the high ALB group. The Kaplan-Meier estimate of survival showed a significant difference in OS among the three groups (log-rank P=0.000).
The early ALB level not only reflects the nutritional and chronic inflammation status of HD patients, but can also predict the prognosis, which has guiding significance for the management of HD patients.

The treatment of insomnia mainly includes drug therapy and non-drug therapy (cognitive behavioral therapy [CBT]). Traditional face-to-face CBT is affected by factors such as location, time, and treatment cost, making the treatment impossible to implement effectively. With the continuous development of network technology, internet-based CBT (ICBT) has been widely used due to the advantages of time and location.
It searched the China National Knowledge Internet (CNKI) database (1979-Apr 2021), China Biomedical Literature Database (1994-Apr 2021), Cochrane Library (2005-Apr 2021), Medline (1948-Apr 2021), and Embase (Jan 1966-Apr 2021). Chinese and English databases were searched using the following terms internet-based cognitive behavioral therapy, cognitive behavioral therapy, sleep problems, and sleep disorders. Meta-analysis was performed using RevMan 5.3 and Stata SE 12.0 software provided by the Cochrane collaboration.

To clarify the efficacy and safety of traditional Chinese medicine (TCM) bath in the treatment of psoriasis vulgaris, meta-analysis and systematic evaluation were adopted to comprehensively evaluate the published articles.
Combing the terms "traditional Chinese medicine bath" and "psoriasis vulgaris", the articles were searched for in the databases of China Knowledge Network (CNKI), Baidu scholar, Wanfang, Chinese Biomedical Literature Database (CBM), Weipu Database, Medline, Embase, Chinese Medical Citation Index (CMCI), and PubMed. The quality of articles was evaluated using the RevMan 5.3 software provided by the Cochrane system.
A total of 13 articles were included. From the funnel chart drawn, it could be seen that the circles and the midline of most articles were not symmetrical, and the publication was biased, so the conclusions obtained were relatively credible. The heterogeneity analysis of TCM bath in treatment of psoriasis vulgaris showed that 13 articles reporting the total effective rate (Tty of psoriasis were lower in the experimental group, so it was concluded that the TCM bath had a significant effect on the treatment of psoriasis vulgaris.
Cerebrovascular disease is one of the leading causes of death and disability in China. Preventive measures to reduce the incidence of cerebrovascular disease are important, so the risk factors associated with death need to be identified. Most studies showed that cerebrovascular disease has many risk factors for death, such as hypertension, hyperlipidemia, family history of stroke, diabetes, overweight, alcohol consumption, and smoking.
A literature search was conducted in the English database PubMed and Chinese databases including CNKI, VIP, and China Journal Full-text Database. The time limit for retrieval was from establishment of the database to March 2021. All randomized controlled trials (RCTs) involving hypertension, hyperlipidemia, family history of stroke, diabetes, overweight, drinking, smoking and cerebrovascular diseases (i.e., stroke and cerebral infarction) were included. Review Manager 5.3 provided by the Cochrane Collaboration was used for meta-analysis.
A total of 10 studies (with 32,664he mortality of patients.
The 10 articles included in this meta-analysis studied the effects of various mortality risk factors (hypertension, hyperlipidemia, family history of stroke, diabetes, overweight, alcohol consumption, and smoking) on the death of patients with emergency cerebrovascular diseases in the Department of Neurology. Attention should be paid to the treatment or care of the above factors in clinical practice to reduce the mortality of patients.A visual detection method was proposed for polychlorinated biphenyls (PCBs) detection using lateral flow test paper as the sensing platform. The aptamer sequence was used to recognize the target 3,3',4,4'-tetrachlorobiphenyl (PCB77). The integration of Zn2+-dependent DNAzyme with toehold-mediated strand displacement reaction significantly improved the response signals. Gold nanoparticles were utilized as the signal tracers in the test paper, making the results visible directly by the naked eye. Under optimal conditions, the paper enables the visual detection of PCB77 as low as 10 pM without additional instrumentation. The assay displays a high selectivity for PCB77 against potential interfering molecules. The visual test paper is robust and has been applied to the detection of PCB77 in milk samples with good recovery and satisfactory accuracy. Using two different PCBs (PCB77 and PCB72) as inputs, we further fabricated OR and AND logic gates, which is conducive to the development of an intelligent detection strategy for PCBs monitoring. Given the attractive characteristics of disposability, low cost, logic operation, and intuitive output, the test paper shows great promise for on-site screening of PCBs in resource-limited areas.ConspectusLithium (Li) metal is the ultimate negative electrode due to its high theoretical specific capacity and low negative electrochemical potential. However, the handling of lithium metal imposes safety concerns in transportation and production due to its reactive nature. Recently, anode-free lithium metal batteries (AFLMBs) have drawn much attention because of several of their advantages, including higher energy density, lower cost, and fewer safety concerns during cell production compared to LMBs. Pushing the reversible Coulombic efficiency (CE) of AFLMBs up to 99.98% is key to achieving their 80% capacity retention over more than 1000 cycles. However, interfacial irreversible phenomena such as electrolyte decomposition reactions on both electrodes, dead Li formation, and Li dendrite formation result in poor capacity retention and short circuits in LMBs and AFLMBs. Therefore, it is of great importance and scientific interest to explore those interfacial irreversible phenomena to improve the cell's cycland AFLMBs. Therefore, we also suggest that the anode-free configurations with significant irreversible phenomena can effectively screen and develop new electrolytes. Finally, the concepts of the protocol with an anode-free cell combined with various advanced analytical tools can be extended to provide an in-depth understanding of other metal batteries and solid-state anode-free metal batteries.A tandem cyclization between 2-(2-aminophenyl)acetonitriles and 2-(hydroxy(aryl)methyl)phenols for the preparation of dihydrochromeno[2,3-b]indole derivatives was successfully developed. The transformation proceeded smoothly in the presence of a catalytic environmentally benign iron salt, and various multisubstituted dihydrochromeno[2,3-b]indoles were synthesized in moderate to high yields.Photosensitizers play a critical role in photodynamic therapy (PDT). Multifunctional organic nanoparticles (NPs) that possess bright fluorescence in aggregates, high singlet oxygen (1O2) quantum yield, near-infrared (NIR) absorption and emission, large Stokes shift, two-photon bioimaging, specific organelle targeting, high PDT efficiency, as well as good biocompatibility and photostability are ideal candidate photosensitizers for image-guided PDT. Due to its enhanced fluorescence and high 1O2 generation efficiency in aggregate states, photosensitizers with aggregation-induced emission (AIE) characteristics have attracted increasing interest in PDT. In this study, a new AIE-active Schiff base 5-(((5-(7-(4-(diphenylamino)phenyl)benzo[c][1,2,5]thiadiazol-4-yl)thiophen-2-yl)methylene)amino)-3-methylthiophene-2,4-dicarbonitrile (TBTDC) based on a D-A-π-A skeleton has been designed and synthesized, and it can be readily encapsulated by Pluronic F-127 to form uniform nanoparticles. TBTDC NPs exhibit bright NIR emission at 825 nm with a Stokes shift up to 300 nm, impressive two-photon bioimaging capability with tissue penetration deep into 300 μm, high 1O2 generation quantum yield (0.552), specific targeting to lysosome, as well as good biocompatibility and photostability. Furthermore, TBTDC NPs present remarkable cytotoxicity for tumor cells and suppression of tumor growth in nude mice through reactive oxygen species generation upon white light irradiation. These results reveal that TBTDC NPs have great potential to become excellent candidates for multifunctional organic photosensitizers for two-photon bioimaging and image-guided PDT and are promising in future clinical applications.A high-throughput lipid profiling platform adopting an accurate quantification strategy was built based on Q-Orbitrap mass spectrometry. Lipid components of fresh walnut during postharvest storage were determined, and the fatty acid distributions in triacylglycerol and polar lipids were also characterized. A total of 554 individual lipids in fresh walnut were mainly glycerolipids (56.7%), glycerophospholipids (32.4%), and sphingolipids (11%). With the progress of postharvest storage, 16 lipid subclasses in the stored walnut sample were significantly degraded, in which 34 lipids changed significantly between the fresh and stored groups. The sphingolipid metabolism, glycerolipid metabolism, and linoleic acid metabolism pathways were significantly enriched. The oxidation and degradation mechanism of linoleic acid in walnut kernel during postharvest storage was proposed. The established lipidomics platform can supply reliable and traceable lipid profiling data, help to improve the understanding of lipid degradation in fresh walnut, and offer a framework for analyzing lipid metabolisms in other tree nuts.Colanic acid has promising applications in food, cosmetic, and healthcare fields.
