[Clinical trial of electroacupuncture at Neimadian-point for cancer pain].

Objective: To observe the clinical efficacy and safety of electroacupuncture (EA) at Neimadian-point for cancer pain.

Methods: A total of 140 cancer patients with pain were randomly divided into EA and control groups, with 70 cases in each group. The patients of the EA group received EA at Neimadian-point plus analgesia pump (all prepared with normal saline).

Sevoflurane inhibits ferroptosis: A new mechanism to explain its protective role against lipopolysaccharide-induced acute lung injury.

Sevoflurane (Sev) has protective effects in acute lung injury (ALI), but the relevant mechanisms are still not fully understood. The present study aimed to determine whether Sev exerts a protective effect on lipopolysaccharide (LPS)-induced ALI by regulating ferroptosis. In this study, we found that Sev could protect mice from lung injury caused by LPS stimulation, including extenuating lung histological damage, pulmonary edema and pulmonary vascular permeability, and the content of inflammatory factors in Bronchoalveolar lavage fluid (BALF), as well as improving the survival rate of ALI mice, which was in line with the effects of ferroptosis inhibitor ferrostatin-1.

[Comparative study between electroacupuncture at Neima point and Neiguan (PC 6) and epidural nerve block for preemptive analgesia in patients undergoing thoracic surgery].

Objective: To compare the clinical effect between electroacupuncture (EA) at Neima point and Neiguan (PC 6) and epidural nerve block for preemptive analgesia in patients undergoing thoracic surgery.

Methods: Sixty patients with elective radical esophagectomy were randomly divided into a group A, a group B and a control group, 20 cases in each group. The patients in the group A were treated with injection of 20 mL 0.

Sevoflurane modulates the cancer stem cell-like properties and mitochondrial membrane potential of glioma via Ca-dependent CaMKII/JNK cascade.

Aims: Gliomas are responsible for the majority of deaths from primary brain tumours. Sevoflurane showed inhibition effects on the tumor progression in vitro. However, whether sevoflurane could affect the stemness of glioma stem cells (GSCs) and the potential molecular mechanism have not been well elucidated.

Activation of RXR by bexarotene inhibits inflammatory conditions in human rheumatoid arthritis fibroblast‑like synoviocytes.

Rheumatoid arthritis (RA) is a debilitating joint disease characterized by chronic inflammation, pathologic alteration of fibroblast‑like synoviocytes (FLS), destruction of cartilage and bone, and the formation of an invasive pannus. RA‑FLS exhibit increased proliferation and resistance to apoptosis. The retinoid X receptor (RXR) has a role in regulating cell cycle, differentiation and apoptosis, and agonism of RXR has been investigated as a treatment strategy in several types of cancer.

Elevated expression of DJ-1 (encoded by the human PARK7 gene) protects neuronal cells from sevoflurane-induced neurotoxicity.

Sevoflurane, an inhaled ether general anesthetic agent, exerts a variety of neurotoxic effects, including oxidative stress, mitochondrial dysfunction, and neuronal apoptosis. However, the underlying molecular mechanisms remain to be elucidated. DJ-1 is a protein that exerts neuroprotective effects against different kinds of stress through multiple pathways.

Ropivacaine regulates the expression and function of heme oxygenase-1.

As a new generation of amide-type local anesthetics (LAs), ropivacaine has been widely used for pain management in clinical settings. Increasing evidence has shown that administration of ropivacaine causes cytotoxic effects and apoptosis. However, the underlying molecular mechanisms still need to be elucidated.

[Clinical research of electroacupuncture on the analgesic effect of thoracic perioperative stage].

Objective: To discuss the clinical therapeutic effects of electroacupuncture at Neimadian (Extra) and Neiguan (PC 6) on the analgesic effect of thoracic perioperative stage and its effect mechanism.

Methods: Sixty cases of esophageal cancer with elective radical resection under general anesthesia were divided into an observation group and a control group according to the operation sequence, 30 cases in each one. In the control group, the general anesthesia was simply applied and sufentanil was administered for patient controlled intravenous analgesia (PCIA) after operation.

Sevoflurane anesthesia in pregnant rats negatively affects nerve function in offspring potentially via inhibition of the Wnt/β-catenin pathway.

Due to the rapid development of medical technology used to perform intrauterine procedures during pregnancy, the number of patients receiving fetal surgery under general anesthesia is increasing. The aim of the present study was to determine the effects of anesthetics on the offspring of rats, and to identify the potential mechanisms underlying these effects. On day 14 of pregnancy, Sprague‑Dawley rats were equally divided into the following 3 groups (n=9): Control group (n=3), 3% sevoflurane group (n=3) and 4% sevoflurane group (n=3).

Dexmedetomidine Regulates 6-hydroxydopamine-Induced Microglial Polarization.

Microglia have undergone extensive characterization and have been shown to present distinct phenotypes, such as the M1 or M2 phenotypes, depending on their stimuli. As a highly specific neurotoxin, 6-hydroxydopamine (6-OHDA) can be used to further our understanding of the immune response in Parkinson's disease (PD). Dexmedetomidine (DEX), a centrally selective α2-adrenoceptor agonist, performs very well as an anti-anxiety medication, sedative and analgesic.

[Observation on electroacupuncture at neimadian (extra) and neiguan (PC 6) for analgesia after thoracic surgery].

Objective: To observe the effectiveness and safety of electroacupuncture (EA) at Neimadian (Extra) and Neiguan (PC 6) for analgesia after thoracic surgery.

Methods: One hundred and twenty cases of thoracic surgery were randomly divided into an electroacupuncture (EA) group (60 cases) and a medication group (60 cases). EA was applied at Neimadian (Extra) and Neiguan (PC 6) for postoperation analgesia in the EA group, while patient-controlled intravenous analgesia (PCIA) was applied in the medication group.

Dexmedetomidine protects against ischemia-reperfusion injury in rat skeletal muscle.

Background: Dexmedetomidine (DEX) has been shown to decrease ischemia-reperfusion (I/R) injury in kidney and brain tissues. In this study, the effects of DEX were evaluated in skeletal muscle during I/R injury.

Materials And Methods: Animals were divided into four groups: sham-operated (sham group), saline + I/R, DEX + I/R, and α-tocopherol + I/R groups.

Study on the DNA repair gene XRCC1 and XRCC3 polymorphism in prediction and prognosis of hepatocellular carcinoma risk.

Background/aims: We conducted a case-control study in China to clarify the association between XRCC1-Arg-399Gin polymorphism and HCC risk.

Methodology: A total of 150 cases and 158 controls were selected from May 2008 to May 2010. XRCC1-Arg399Gin and XRCC3-Thr241Met polymorphisms were based upon duplex polymerase-chain-reaction with the confronting-two-pair primer (PCR-CTPP) method.
