[Effects of unilateral thoracic paravertebal block on hemodynamic and the level of conscionsness during double lumen endotracheal intubation].

Objective: To compare the effects of unilateral thoracic paravertebal block with lidocaine on hemodynamic and the level of consciousness during double lumen endotracheal intubation.

Methods: From June to october 2021, a total of 40 patients American Society of Anesthesiologists (ASA) physical status Ⅰ-Ⅱ, aged 19-65 years, scheduled for elective thoracic sugeries in Peking University International Hospital block with under general anesthesia requiring orotracheal intubation were recruited and divided into two groups: The double-lumen endobronchial intubation (group C) and double-lumen endobronchial intubation after thoracic paravertebal block with lidocaine (group P). After an intravenous anesthetic induction, the orotracheal double-lumen intubation was performed using a Macintosh direct laryngoscopy, respectively.

Impact of Dexmedetomidine Dosing and Timing on Acute Kidney Injury and Renal Outcomes After Cardiac Surgery: A Meta-Analytic Approach.

Background: Acute kidney injury (AKI) is a common and serious complication following cardiac surgery. Dexmedetomidine, a highly selective α2-adrenergic agonist, has shown potential renoprotective effects, but previous studies have yielded conflicting results.

Objective: This meta-analysis aimed to evaluate the efficacy and safety of dexmedetomidine in preventing AKI and reducing postoperative serum creatinine levels in adult patients undergoing cardiac surgery.

Deciphering mitochondrial dysfunction: Pathophysiological mechanisms in vascular cognitive impairment.

Vascular cognitive impairment (VCI) encompasses a range of cognitive deficits arising from vascular pathology. The pathophysiological mechanisms underlying VCI remain incompletely understood; however, chronic cerebral hypoperfusion (CCH) is widely acknowledged as a principal pathological contributor. Mitochondria, crucial for cellular energy production and intracellular signaling, can lead to numerous neurological impairments when dysfunctional.

Nunchaku: optimally partitioning data into piece-wise contiguous segments.

Motivation: When analyzing 1D time series, scientists are often interested in identifying regions where one variable depends linearly on the other. Typically, they use an ad hoc and therefore often subjective method to do so.

Results: Here, we develop a statistically rigorous, Bayesian approach to infer the optimal partitioning of a dataset not only into contiguous piece-wise linear segments, but also into contiguous segments described by linear combinations of arbitrary basis functions.

Clinical HDAC Inhibitors Are Effective Drugs to Prevent the Entry of SARS-CoV2.

The outbreak of COVID-19 by the end of 2019 has posed serious health threats to humanity and jeopardized the global economy. However, no effective drugs are available to treat COVID-19 currently and there is a great demand to fight against it. Here, we combined computational screening and an efficient cellular pseudotyped virus system, confirming that clinical HDAC inhibitors can efficiently prevent SARS-CoV-2 and potentially be used to fight against COVID-19.

Dexmedetomidine in combination with ketamine for pediatric procedural sedation or premedication: A meta-analysis.

Objective: To evaluate effectiveness of combinational use of dexmedetomidine and ketamine (DEX-KET) for pediatric procedural sedation or premedication.

Methods: Relevant studies were identified after a literature search in electronic databases and study selection was based on precise eligibility criteria. Meta-analyses of mean differences were performed to examine differences in sedation onset and recovery times between DEX-KET and comparators.

[Comparison between Ye Tianshi and Xue Shengbai in treatment of diarrfea with damp-heat].

Ye Tianshi and Xue Shengbai are two febrile disease specialists in same time, and for the treatment of dampness and heat, they have different medication ideas. With the help of traditional Chinese medicine(TCM), author has studied two specialists' consilias of dampness and heat, through the statistics and analysis of their medicine during the treatment of dampness and heat, summarizes the similarities and differences of Ye and Xue's medicine application's assoations and models. Ye Tianshi and Xue Shengbai were both thought that the reason of dampness and heat was damp heat pathogenic factors, for this reason, the spleen and stomach conduction disordered, They both treated from the middle-jiao of Yangming and Taiyin, focused on warm-natured medicine, cold-natured medicine, used less cool-natured and heat-natured medicine, and more bitter, pungent, sweet medicine; Ye Tianshi usually use Scutellariae Radix, Paeoniae Radix Alba, Coptidis Rhizoma, Polyporus, Poria, Alismatis Rhizoma; Xue Shengbai commonly use Poria, Citri Reticulatae Pericarpium, Magnoliae officinalis Cortex, Patchouli, Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Alba, Lablab Semen Album, Puerariae Lobatae Radix, Mume Fructus, Tsaoko Fructus, Amomi Fructus, Coptidis Rhizoma and Phellodendri Chinensis Cortex.

[Comparison between Ye Tianshi and Xue Shengbai in treatment of distention with damp-heat].

Ye Tianshi and Xue Shengbai were both epidemic febrile diseases specialists in same time of Qing dynasty. The Traditional Chinese Medicine Inheritance Support System was used to compare and analyze the therapeutic characteristics of these two specialists in treating damp-heat type fullness or distension in stomach. Distension is commonly caused by qi stagnation accompanied with damp-heat from internal and external factors.
