Esketamine combined with sufentanil sufentanil in patient-controlled intravenous analgesia: a meta-analysis.

Patient-controlled intravenous analgesia (PCIA) can alleviate pain to some extent, and several randomized controlled trials (RCTs) have examined the efficacy of esketamine-assisted sufentanil in postoperative PCIA. In this research, we conducted a meta-analysis of relevant RCTs to compare the effect and safety of esketamine-sufentanil sufentanil alone for postoperative PCIA. We systematically searched the Cochrane Library, PubMed, Embase, Web of Science, CNKI, and other libraries up to December 2023 to screen out RCTs examining the use of esketamine combined with sufentanil for PCIA.

Simultaneous determination of 14 analgesics in postoperative analgesic solution by HPLC-DAD and LC-MS/MS.

A green, efficient, sensitive and accurate detection method by HPLC-DAD and LC-MS/MS was developed and validated for the quantification of morphine, hydromorphone, oxycodone, ketamine tramadol, dezocine, ropivacaine, remifentanil, butorphanol, bupivacaine, droperidol, fentanyl, lornoxicam and sufentanil. The 14 mixtures were chromatographed via HPLC-DAD method which employed 0.05 mol/L potassium dihydrogen phosphate solution-acetonitrile as the mobile phase, the analytes were gradient elution on a SinoChrom ODS-BP C column with a total separation time of 35 min, and 14 mixtures showed a good linear relationship in the linear range.

Study of Scraping with Copper Stone Based on Theory of Midnight-Noon Ebb-Flow in Angina Pectoris with Coronary Heart Disease of Qi Stagnation and Blood Stasis.

Angina pectoris (AP) with coronary heart disease (CHD) is one of the common cardiovascular diseases in clinical practice, which can be classified as "chest paralysis" in Chinese medicine according to its symptoms, and it is described in many ancient documents. Ancient Chinese medicine believes that the main pathogenesis of the disease is poor blood flow leading to paralysis of the heart and veins, so it is often treated by activating blood and removing blood stasis. In this study, 120 patients with AP of CHD of Qi stagnation and blood stasis type were randomly divided into the observation ( = 60) and the control group ( = 60).

Micropapillary Predominant Lung Adenocarcinoma in Stage IA Benefits from Adjuvant Chemotherapy.

Purpose: The benefit of adjuvant chemotherapy remains unknown for patients with stage IA micropapillary predominant (MPP) lung adenocarcinoma (ADC). This study investigated the effect of adjuvant chemotherapy in ADC and MPP patients in stage IA.

Methods: A total of 5220 stage IA lung ADC patients from SEER database and 152 MPP subtype patients from Qilu Hospital of Shandong University were retrospectively analyzed.

High Thermal Conductivity of Flake Graphite Reinforced Polyethylene Composites Fabricated by the Powder Mixing Method and the Melt-Extruding Process.

The thermal conductivity of flake graphite (FG) particulates reinforced high density polyethylene (HDPE) composites was systematically investigated under a special dispersion state of FG particles. The effects of particle size, weight filling ratio and proportion of various sizes were discussed in detail. A special composite (15 wt % 500 μm/10 wt % 200 μm/10 wt % 20 μm/5 wt % 2 μm FG + 60 wt % polyethylene (PE)) with a high thermal conductivity about 2.

Protective effects on vascular endothelial cell in N'-nitro-L-arginine (L-NNA)-induced hypertensive rats from the combination of effective components of Uncaria rhynchophylla and Semen Raphani.

Endothelial dysfunction is closely associated with hypertension. Protection of vascular endothelial cell is the key to prevention and treatment of hypertension. Uncaria rhynchophylla total alkaloids and Semen Raphani soluble alkaloid, isolated from traditional Chinese medicine Uncaria rbyncbopbylla and Semen Raphani respectively, exhibit properties of anti-hypertension and protection of blood vessels.

Butorphanol and ketamine combined in infusion solutions for patient-controlled analgesia administration: a long-term stability study.

Background: Ketamine in subanesthetic dose added to butorphanol has been reported to give superior pain control when used for intravenous patient-controlled analgesia (PCA) after surgery. However, this admixture is not available commercially and stability data applicable to hospital practice are limited.

Material/methods: The butorphanol-ketamine admixtures were prepared in polyolefin bags and stored in the dark at 4°C, 25°C, or 37°C for 15 days.

Stability of butorphanol-tropisetron mixtures in 0.9% sodium chloride injection for patient-controlled analgesia use.

Tropisetron is an adjuvant for butorphanol used in intravenous patient-controlled analgesia (PCA) and has been reported to provide superior pain control. It is efficacious in reducing the incidence of postoperative nausea and vomiting. However, this admixture is not available commercially and stability data applicable to hospital practice are limited.

Noncovalent functionalization of graphene attaching [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) and application as electron extraction layer of polymer solar cells.

A new graphene-fullerene composite (rGO-pyrene-PCBM), in which [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) was attached onto reduced graphene oxide (rGO) via the noncovalent functionalization approach, was reported. The pyrene-PCBM moiety was synthesized via a facile esterification reaction, and pyrene was used as an anchoring bridge to link rGO and PCBM components. FTIR, UV-vis, and XPS spectroscopic characterizations were carried out to confirm the hybrid structure of rGO-pyrene-PCBM, and the composite formation is found to improve greatly the dispersity of rGO in DMF.

Compatibility of butorphanol and droperidol in 0.9% sodium chloride injection.

Purpose: The compatibility and stability of butorphanol tartrate and droperidol in polyvinyl chloride (PVC) bags and glass bottles stored at 4°C and 25°C for up to 15 days were studied.

Methods: Admixtures were assessed initially and for 15 days after preparation in PVC bags and glass bottles using 0.9% sodium chloride injection as a diluent and stored at 4°C and 25°C.

Development and evaluation of an indirect enzyme-linked immunosorbent assay for the detection of antibodies against Campylobacter fetus in cattle.

Campylobacteriosis is a zoonosis that occurs worldwide. Infection with Campylobacter fetus (C. fetus) causes infertility and abortion in sheep and cattle.
