RESUMO
The crosstalk between tumor and stroma plays a critical role in cancer metastasis. However, the function of miR-10a-5p on liver fibroblasts in the metastatic microenvironment of colon cancer (CC) and the effect of activated fibroblasts on CC cells are still unclear. In our study, miR-10a-5p overexpression inhibited the proliferation, migration, and IL-6/IL-8 level of LX-2 cells and human liver cancer fibroblasts (HLCFs). Moreover, miR-10a-5p had lower expression in HLCFs than in human liver normal fibroblasts (HLNFs). The conditioned medium (CM) from LX-2 cells with miR-10a-5p overexpression or HLNFs could inhibit the invasion, migration, and stemness of CC SW480 cells, whereas HLCFs CM could promote these malignant phenotypes of SW480 cells. The present study illustrates the effect of miR-10a-5p on the liver fibroblasts and the altered liver fibroblasts in the microenvironment on CC cells induced by miR-10a-5p, which may aid the understanding of the mechanisms underlying CC liver metastasis.

BACKGROUND: Postoperative cognitive dysfunction (POCD) is a common complication after orthopedic surgery, which is not conducive to the prognosis of the elderly. AIMS: We performed this study to investigate the effects of oxycodone applied for patient-controlled intravenous analgesia (PCIA) on postoperative cognitive function in elderly patients after total hip arthroplasty (THA). METHODS: Ninety-nine participants were enrolled and allocated into two groups: oxycodone group (group O) and sufentanil group (group S). The primary outcome was the incidence of POCD, diagnosed according to the changes in the Mini-mental status examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores. The secondary outcomes included the plasma levels of S-100B protein and neuron-specific enolase (NSE), the amount of postoperative analgesic consumption and the incidence of adverse reactions. RESULTS: The incidence of POCD was significantly lower in patients receiving oxycodone up to the 3rd postoperative day (POD, 1st POD 27.3% vs. 51.1%, P = 0.021; 3rd POD 20.5% vs. 40.0%, P = 0.045), as compared to patients receiving sufentanil. The MMSE and MoCA scores of both groups decreased to varying degrees. However, compared with group S, the MMSE scores at 1st POD, 3rd POD, 5th POD and 7st POD in group O were higher than that in group S, while MoCA scores at 1st POD, 3rd POD and 5th POD in group O were higher. Compared with group S, the plasma levels of S-100B protein in group O at 4 h, 8 h, 12 h post-surgery were lower. While the plasma levels of NSE in group O at 4 h, 8 h, 12 h, 24 h post-surgery were lower. Number of PCIA boluses and consumption of analgesic drug during the first two POD were similar between two groups. However, postoperative incidence of nausea, vomiting and pruritus was significantly lower in patients receiving oxycodone. CONCLUSION: Oxycodone applied for PCIA in elderly patients after THA could reduce the incidence of POCD, improve postoperative cognitive function and decrease the adverse reactions.

Objective: To explore the effects of Beck's cognitive therapy on the anxiety of patients after breast reconstruction. Methods: This study retrospectively analyzed clinical data of 150 patients with breast cancer undergoing breast reconstruction from June 2020 to June 2021 in our hospital, excluded 5 patients who did not meet the inclusion criteria, divided the remaining cases into an experimental group (EG, n = 70, perioperative routine management + Beck's cognitive therapy intervention) and a reference group (RG, n = 75, perioperative routine management) in accordance with different perioperative intervention programs, and compared the emotions of anxiety and depression, sense of social disability, and prognosis quality in both groups. Results: At 2 months after surgery (T2) and 3 months after surgery (T3), EG had overtly lower Hamilton Anxiety Scale (HAMA) and Beck Depression Inventory (BDI) scores than RG (P < .05), with no difference in HAMA and BDI scores at 3 days before surgery (T0) and 1 month after surgery (T1) (P > .05). At the T0 stage, both groups were diagnosed as having a social disability, with no overt difference (P > .05). At T1 stage, The Social Disability Screening Schedule (SDSS) scores in both groups increased remarkably and fell back at the T2 and T3 stages. At T1-T2 stages, SDSS scores of EG were significantly different from those of RG (P < .05), with no significant difference at T3 stage (P > .05). The excellent rate of prognosis in EG was 78.57% (55/70), higher than 77.33% (58/75) in RG, with no statistical difference in both groups (P < .05). Conclusion: The implementation of Beck's cognitive therapy in patients with breast reconstruction effectively improves adverse emotions in patients, which is of great significance for promoting postoperative rehabilitation and is an effective intervention program in the perioperative period.
RESUMO
The aim of the present study was to explore the effects of dexmedetomidine (DEX) combined with ketorolac on postoperative patient-controlled analgesia (PCA), the balance of Th1/Th2 and the level of vascular endothelial growth factor (VEGF) in patients with cervical cancer following laparoscopic radical surgery. A total of 70 women with cervical cancer undergoing laparoscopic radical hysterectomy were enrolled in the study to randomly receive postoperative dexmedetomidine combined with ketorolac analgesia (DK group) and postoperative sufentanil analgesia (SUF group). The primary outcomes were the serum levels of interleukin-4 (IL-4), interferon-γ (IFN-γ) and VEGF, and the IFN-γ/IL-4 ratio 30 min before induction (T0), and 24 and 48 h after surgery. Secondary outcomes included numerical rating scale scores at 0 h (T0), 4 h (T1), 12 h (T2), 24 h (T3) and 48 h (T4) postoperatively, cumulative times of rescue analgesia, as well as the incidence of postoperative side effects within 48 h from surgery. Patients in the DK group reported similar analgesic effects as patients in the SUF group at T2, T3 and T4, and the incidence of postoperative nausea and vomiting was significantly lower in the DK group. In the DK group, the serum concentration of IFN-γ and IFN-γ/IL-4 ratio at 24 and 48 h after surgery were higher compared with those in the SUF group. Conversely, the serum concentrations of IL-4 at 24 h after surgery and VEGF at 24 and 48 h after surgery were significantly lower. The results indicated that the combination of DEX and ketorolac for PCA significantly improved postoperative pain and decreased the serum level of VEGF, which are associated with tumor angiogenesis. In addition, it maintained the homeostasis of postoperative immune dysfunction of patients with cervical cancer by shifting the balance between type 1 T helper cells and type 2 T helper cell (Th1/Th2 balance) to Th1 (registration no. ChiCTR1900027979; December 7, 2019).
RESUMO
Seasonal influenza is an annually severe crisis for global public health, and an ideal influenza vaccine is expected to provide broad protection against constantly drifted strains. Compared to highly flexible hemagglutinin (HA), increasing data have demonstrated that neuraminidase (NA) might be a potential target against influenza variants. In the present study, a series of genetic algorithm-based mosaic NA were designed, and then cloned into recombinant DNA and replication-defective Vesicular Stomatitis Virus (VSV) vector as a novel influenza vaccine candidate. Our Results showed that DNA prime/VSV boost strategy elicited a robust NA-specific Th1-dominated immune response, but the traditional inactivated influenza vaccine elicited a Th2-dominated immune response. More importantly, the superior NA-specific immunity induced by our strategy could confer both a full protection against lethal homologous influenza challenge and a partial protection against heterologous influenza infection. These findings will provide insights on designing NA-based universal vaccine strategy against influenza variants.
RESUMO
Cognitive dysfunction is a very common postoperative complication. The study aimed at investigating the effects of ketamine on the cognition of elderly mice after anesthesia and surgery (AS). We reported that AS impaired the cognition of elderly mice, while ketamine helped to maintain the cognitive function. Ketamine decreased the levels of TNF-α, IL-6, IL-1ß and the expression of p-TAU, S100B in hippocampal induced by AS. In addition, AS triggered severe oxidative stress in hippocampal, while ketamine inhibited it. Oxidative stress induced autophagy of hippocampal neurons via inhibiting PI3K/AKT/mTOR pathway. Ketamine could activate PI3K pathway and inhibit autophagy in hippocampal, thus maintain the loss of hippocampal neurons. The study suggested that ketamine inhibited the neuroinflammation and oxidative stress, reduced the autophagy of hippocampal neurons via PI3K/AKT/mTOR pathway. It may provide novel methods for the protection of cognitive function in elderly during perioperative period.

OBJECTIVE: To evaluate the effectiveness and safety of transcutaneous electrical acupoint stimulation (TEAS) for improving postoperative cognitive function in senior patients undergoing video-assisted thoracoscopic surgical (VATS). METHODS: From January to December 2020, 97 participants were randomly assigned to the TEAS group (49 cases) and the control group (48 cases) by a random number table. The patients in the TEAS group received TEAS, at the bilateral Neiguan (PC 6) and Zusanli (ST 36) acupoints. The control group received sham TEAS. The stimulation was started from 30 min before surgery until the end of the operation. The primary outcome was the incidence of pstoperative cognitive dysfunction (POCD), diagnosed based on the changes in the Mini-Mental Status Examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores. The secondary outcomes were plasma levels of S100ß protein and neuron-specific enolase (NSE). RESULTS: The incidence of POCD on day 1 and 3 after surgery in the TEAS group was significantly lower than that in the control group [day 1 after surgery: 28.3% (13/46) vs. 52.3% (23/44), P=0.028; day 3 after surgery: 21.7% (10/46) vs. 40.9% (18/44), P=0.043]. Compared with baseline, the MMSE and MoCA scores decreased to various extents in both groups. The MMSE scores on day 1, 3, and 5 after surgery and MoCA scores on day 1, 3, 5, and 7 after surgery in the TEAS group were higher than those in the control group (all P<0.05) in both groups. Compared with baseline, the plasma levels of S100ß and NSE were significantly increased at 4, 8, 12, 24 h after surgery (all P<0.05). Compared with the control group, the plasma levels of S100ß and NSE were lower in the TEAS group at 4, 8, 12, and 24 h after surgery (all P<0.05). No obvious adverse events were found during the trial. CONCLUSION: Application of TEAS in senior patients after VATS could reduce incidence of POCD and improve postoperative cognitive function.

OBJECTIVE: This research was designed to probe into the effect of multimodal analgesia on gynecological cancer patients after radical resection. METHODS: Ninety-eight cervical cancer patients undergoing laparoscopic radical resection in our hospital were included. Thereinto, 47 in the research group (RG) were given multimodal analgesia, and 51 in the control group (CG) were given conventional postoperative analgesia. The time of operation, anesthesia recovery room observation and extubation, postoperative NRS pain score, and the clinical manifestations of both groups were observed. The activity within three days after operation, the incidence of postoperative complications, hospitalization time and quality of life of both groups were compared. RESULTS: The operation time of the RG was higher than that of the CG (P < 0.05), and the time of observation and extubation in the anesthesia room were lower than those in the CG (P < 0.05); the NRS pain score was lower than that of the CG (P < 0.05); the first time to get out of bed, and time of exhaust and diet were shorter than those of the CG (P < 0.05); the activity was better than that of the CG within three days after operation (P < 0.05); the incidence of complications was markedly lower than that in the CG (P < 0.05); the hospitalization time was shorter than that of the CG (P < 0.05); the postoperative quality of life was shorter than that in the CG (P < 0.05). CONCLUSION: Multimodal analgesia is safe and effective for patients after laparoscopic radical resection of gynecological malignancies, which can speed up the recovery of diseases and improve the quality of life. Thus, it is worthy of clinical application.
RESUMO
Radical mastectomy may lead to suppression of cellular immune function in patients with malignant tumors. Transcutaneous electrical acupoint stimulation (TEAS) is widely used in clinical practice. However, there have been relatively few studies on the effects of TEAS on postoperative analgesia and immune function. The present study aimed to evaluate the effects of TAES on postoperative pain and immune function in patients undergoing radical mastectomy. A total of 65 patients were enrolled and allocated to either receive TEAS or sham TEAS. TEAS was implemented on bilateral Hegu (LI4), Neiguan (PC6) and Zusanli (ST36) acupoints simultaneously for 30 min before induction of anesthesia at 4 and 12 h post-operation. The primary outcomes included visual analogue scale (VAS) scores at 4 h (T1), 12 h T2), 24 h (T3) and 48 h (T4) post-operation, and serum levels of IL-2, IL-4, IFN-γ and the IL-2/IL-4 ratio at 30 min before TEAS (T0), T1, T2, T3 and T4. Secondary outcomes included the cumulative time of rescue analgesia within 48 h post-surgery, as well as the incidence of postoperative nausea and vomiting (PONV) and pruritus. Compared with the sham TEAS group, postoperative VAS scores at T2 and T3, the total consumption of opioids in the patient-controlled analgesia (PCA) pump, pressing times of the PCA pump and the incidences of PONV and headache were significantly lower in the TEAS group. The serum levels of IFN-γ at T3 and T4, and the serum levels of IL-2 and the IL-2/IL-4 ratio at T2, T3 and T4 were higher in the TEAS group compared with the sham TEAS group. By contrast, the serum levels of IL-4 were lower at T2, T3 and T4 in the TEAS group compared with the sham TEAS group. The results indicated that TEAS could improve postoperative analgesia, reduce postoperative consumption of opioids and alleviate postoperative side effects. Simultaneously, TEAS was able to reverse decreased serum levels of IL-2 and IFN-γ, reduce the level of IL-4 and restore the balance of Th1/Th2, thereby partially attenuating perioperative immune function depression in patients with breast cancer. The current trial was registered prior to participant enrollment at www.chictr.org.cn (Clinical Trial no. ChiCTR1800017768).
RESUMO
PURPOSE: Transcutaneous electrical acupoint stimulation (TEAS) is widely used. However, no study evaluated TEAS on systemic inflammatory response syndrome (SIRS) of patients after percutaneous nephrolithotomy (PCNL). The study was to evaluate TEAS on SIRS of patients after PCNL. METHODS: 67 patients were enrolled and divided into group TEAS and group sham TEAS. Data were collected from 60 participants finally. In the study, TEAS or sham TEAS on bilateral Shenshu (BL23), Yinlingquan (SP9), Hegu (LI4), and Neiguan (PC6) was performed continuously throughout the procedure. The primary outcome included the incidence of systemic inflammatory response syndrome (SIRS) within 48 h after surgery. The secondary outcomes included the serum levels of inflammatory cytokines, hemodynamics changes, complications, and hospital stay after surgery. The serum levels of tumor necrosis factor- (TNF-) α and interleukin- (IL-) 6, mean arterial pressure (MAP), and heart rate (HR) at 30 min before anesthesia (T 0), the time after surgery (T 1), 24 h postoperation (T 2), and 48 h postoperation (T 3) were recorded. The consumption of analgesic during surgery was also recorded, as well as the complications and duration of hospital stay after PCNL. RESULTS: The incidence of SIRS in group TEAS was lower than group sham TEAS (30% vs. 6.67%, p=0.023). Compared with the sham TEAS group, both levels of TNF-α and IL-6 at T 1, T 2, and T 3 were lower in the TEAS group (p < 0.05). The levels of MAP and HR in sham TEAS at T 1, T 2, and T 3 were markedly higher than that in the TEAS group (p < 0.05). The total consumption of propofol and remifentanil during surgery in group TEAS was lower than that in the sham TEAS group. The incidence of hypotension, hypertension, emergence agitation, and postoperative nausea and vomiting (PONV) was also lower in group TEAS after PCNL (p < 0.05). CONCLUSIONS: TEAS could effectively reduce the incidence of SIRS and inflammatory cytokines for patients who underwent PCNL. In addition, TEAS helped to maintain the hemodynamic stability and cut down the consumption of analgesics during PCNL, reducing the complications after PCNL.
RESUMO
This study consisted of two rounds of cross-sectional observations designed to evaluate the persistence of immune protection induced high antigen content hepatitis B (HB) vaccine at 60 µg/1.0 ml formulations administered at a three-dose schedule (Days 0, 28, and 56) in non-responders to routine HB vaccination. In the original phase 3 study, we enrolled 1091 healthy participants (16-60 years old) seronegative for antibody against HB surface antigen (anti-HBs) after primary vaccination. Participants were randomized (2:2:1) to receive three booster doses of HB vaccine containing 60 µg, 30 µg, or 10 µg of antigen per dose 28 days apart. In the group receiving the 60 µg HB vaccine, 428 participants' serum samples were available at pre-vaccination and 28 days after each vaccine dose and were included in immunogenicity analysis. With two written informed consents, we collected blood samples from 276 (67.2%) participants in 2014 and 239 (58.2%) in 2019, who had completed the full course of revaccination and reached the seropositive (anti-HBs≥10 mIU/ml) standard in the 60 µg vaccine group of the original phase 3 study. The HBV seropositive rate was found to decrease from 96.0% in 28 days after receiving the third dose of 60 µg HB vaccine, to 48.2% in 2014, and to 40.6% in 2019, with anti-HBs GMC of seropositive individuals was 584.0 mIU/ml, 142.4 mIU/ml, and 169.1 mIU/ml, respectively. Analysis of 181 vaccinees who had serologic test results available both in 2014 and in 2019, and results revealed a dynamic trend in anti-HBs titer similar to that for the whole immune persistence cohort. Of paramount importance, the serologic test results found that 24.9% (45/181) participants had higher anti-HBs concentrations in 2019 than in 2014, this could be interpreted as natural boosters, secondary to HBV exposure without infection because protected. In conclusion, protective antibody persists about 11 years after immunization of Chinese non-responders with 3 doses of 60 µg HB vaccine. Booster doses of vaccine do not seem necessary to ensure long-term protection.

MicroRNAs (miRs) carried in exosomes serve an important role in the premetastatic microenvironment and in intercellular interactions. However, the function of exosomalmiR10a derived from primary colorectal cancer (CRC) cells on fibroblasts in the lung metastatic microenvironment of patients with CRC remains unclear. Reverse transcriptionquantitative PCR was performed using samples from patients with CRC, and demonstrated that the expression levels of miR10a were significantly lower in serum and cancer tissue samples from patients with CRC compared with in serum from healthy individuals and paired noncancerous tissues, respectively. In addition, the expression levels of miR10a were inversely associated with the invasion depth of CRC. ExosomalmiR10a derived from CRC cells reduced the proliferative and migratory activities of primary normal human lung fibroblasts (NHLFs), and the expression levels of IL6, IL8 and IL1ß in NHLFs. The present study provided insight into the phenotypic alterations of NHLFs induced by exosomalmiR10a derived from CRC cells, which may aid understanding of the mechanism underlying the process of CRC lung metastasis.

Patients undergoing cardiac valve replacement may experience cardiovascular adverse events during the preoperative period before anesthesia. The study was to compare the preemptive anti-stress response effects of oxycodone versus sufentanil for patients undergoing cardiac valve replacement. Ninety-four patients were enrolled and assigned to group Oxy, group Suf and group NS. Patients in group Oxy were administrated with oxycodone 0.1 mg/kg, group Suf received sufentanil 0.1 µg/kg and group NS were given equivalent volume of normal saline. The primary outcomes included serum levels of cortisol, norepinephrine, and adrenaline. The secondary outcomes involved bispectral index value and the observer's assessment of awareness/sedation grade, levels of mean arterial pressure, heart rate, and the adverse reactions. Compared to group NS, the serum levels of cortisol at T1 to T5 (P < .05), and levels of norepinephrine and adrenaline at T3 to T5 (P < .05) in group Oxy and Suf were lower. The bispectral index value and observer's assessment of awareness/sedation grade T1 to T2 (P < .05) in group Suf were lower than those in group Oxy and NS. Compared with group NS, the levels of mean arterial pressure and heart rate in group Oxy and Suf at T3 to T5 (P < .05) were lower. The incidence of coughing was significantly higher in group Suf (23.3%), but not in group NS (6.7%), than that in group Oxy (3.3%). The preemptive analgesia of oxycodone may be used to inhibit the stress response, without leading to excessive sedation and respiratory depression, which may also help to stabilize hemodynamics during preoperative period.

Fraxinus rhynchophylla belongs to the family of Oleaceae and also called as Chinese ash wood possesses various pharmacological properties such as neuroprotective, antimicrobial, anti-inflammatory, etc. Therefore we synthesized ZnO nanoparticles using Fraxinus rhynchophylla wood extract as reducing and capping agent. The synthesized nanoparticles were characterized with the aid of UV-Spec, DLS, FT-IR and TEM analysis. Green synthesized ZnO nanoparticles were then assessed for anti-nociceptive property by using various nociception models such as thermal stress-induced, acetic acid, glutamate, capsaicin, and formalin-induced nociception. The sedative effect of synthesized ZnO nanoparticles was evaluated with an open field test. UV-Spectroscopic analysis confirms the formation of ZnO nanoparticles and the characterization studies DLS, FT-IR, and TEM analysis prove it has ideal nanoparticle can be used as a nano-drug. Results of both thermal stress-induced methods hot plate and tail immersion nociception test verified the synthesized ZnO nanoparticles are a potent antinociceptive drug. ZnO nanoparticles effectively reduced the abdominal writhes in acetic acid-induced nociception and it also significantly decreased the nociception activity in another glutamate, capsaicin, and formalin-induced nociception models. Open field experiment proved that synthesized ZnO nanoparticles are less sedative compared to the standard antinociceptive drug morphine. Overall our findings authentically confirm ZnO nanoparticles synthesized from Fraxinus rhynchophylla wood extract is a novel drug that persuasively reduces nociception in different nociceptive induced mice models and can be the best alternative for allopathic drugs which renders severe side effects.

OBJECTIVE: The meta-analysis was conducted to assess the effectiveness and safety of intravenous administration of dexmedetomidine for cesarean section under general anesthesia, as well as neonatal outcomes. MATERIALS AND METHODS: We searched PubMed, Embase, Cochrane Central Register of Controlled Trials and the China National Knowledge Infrastructure database for relevant randomized controlled trials (RCTs) about the application of intravenous dexmedetomidine under general anesthesia for cesarean section. RevMan 5.3 was used to conduct the meta-analysis of the outcomes of interest. RESULTS: Eight RCTs involved 376 participants were included in this study. The meta-analysis showed that the mean blood pressure at the time of intubation (weighted mean difference [WMD]: -15.67, 95% CI: -21.21, -10.13, P<0.00001), skin incision (WMD: -12.83, 95% CI -20.53, -5.14, P=0.001), and delivery (WMD: -11.65, 95% CI -17.18, -6.13, P<0.0001) in dexmedetomidine group were significantly lower than that in the control group. The heart rate (HR) at the time of intubation (WMD: -31.41, 95% CI -35.01, -27.81, P<0.00001), skin incision (WMD: -22.32, 95% CI -34.55, -10.10, P=0.0003), and delivery (WMD: -19.07, 95% CI -22.09, -16.04, P<0.00001) were also lower than that in control group. For neonatal parameters, no differences existed in umbilical blood gases at delivery, and Apgar scores at 1 minute (WMD: -0.12, 95% CI -0.37, 0.12, P=0.33) and 5 minutes (WMD: -0.17, 95% CI -0.13, 0.46, P=0.27) among two groups. CONCLUSION: Intravenous administration of dexmedetomidine could efficiently attenuate the maternal cardiovascular response during cesarean section, without affecting Apgar score of the neonate.

OBJECTIVE: To elaborate the analgesic efficiency of midazolam-induced anesthesia in different doses on the patients following the thoracoscopic resection of lung cancer. METHODS: Ninety patients undergoing thoracoscopic resection of lung cancer between August 2017 and July 2018 were randomized in the observation group (nâ¯=â¯45) and the control group (nâ¯=â¯45). Patients in observation group underwent the anesthesia induced by 0.1â¯mg/kg midazolam, while for the control group, the dose was adjusted to 0.05â¯mg/kg. Then, we compared the levels of inflammatory factors, SaO2, average of arterial pressure and changes in heart rate before and after surgery (48â¯h) to analyze the efficacy. RESULTS: At the postoperative 48â¯h, patients in the observation group had lower levels of inflammatory factors when comparing with their counterparts in the control group [IL-6, IL-8, IL-1ß and TNF-α: (58.44⯱â¯3.22)⯵g/L, (2.04⯱â¯0.26)⯵g/L, (2.98⯱â¯0.44)⯵g/L, (5.33⯱â¯0.77)⯵g/L v.s. (96.44⯱â¯4.54)⯵g/L, (3.23⯱â¯0.33)⯵g/L, (3.77⯱â¯0.44)⯵g/L, (7.64⯱â¯0.99)⯵g/L] (Pâ¯<â¯0.05). Meanwhile, those in the observation group had a lower SaO2, average arterial pressure and heart rate [(93.79⯱â¯1.08)%, (93.22⯱â¯3.46)â¯mmHg, (87.55⯱â¯2.35) beat/min v.s. (97.13⯱â¯1.03)%, (96.44⯱â¯4.03)â¯mmHg, (91.05⯱â¯2.89) beat/min] (Pâ¯<â¯0.05). However, no statistical significance was identified in the differences of the bleeding amount, surgical time and anesthesia time between two groups (Pâ¯>â¯0.05), while the eye-opening time and the extubation time in the observation group were all shorter than those in the control group (Pâ¯<â¯0.05). Similarly, the postoperative pain scores, total doses of propofol and remifentanil were also lowered (Pâ¯<â¯0.05). CONCLUSION: For patients of thoracoscopic resection of lung cancer, midazolam-induced anesthesia (0.1â¯mg/kg) performs better than 0.5â¯mg/kg in inhibiting the inflammatory responses, with significant reduction in the dose of anesthetics, thereby stabilizing the status of patients in perioperative period and mitigating the postoperative pains. Thus, it is potential candidate.
RESUMO
Transcutaneous electrical acupoint stimulation (TEAS) is an effective analgesic measure. We studied the analgesic effect of TEAS by applying it alone after ureteroscopic lithotripsy, rather than applying it as a supplementary analgesic measure. Participants (n = 120) scheduled to undergo ureteroscopic holmium laser lithotripsy, were enrolled and randomly assigned into Group T (TEAS n = 60) and Group C (Control, n = 60). The participants in Group T were treated with TEAS for postoperative analgesia. TEAS were implemented on bilateral Shenyu (BL23) and Yinlingquan (SP9) at the time backward and the time at 4, 8, 12 h postoperatively. TEAS was re-implemented three times on the target acupoints for the next 2 days. When TEAS failed to meet the analgesic effect, the participants were given tramadol hydrochloride tablets of 100 mg. Participants of Group C were given tramadol hydrochloride tablets for postoperative analgesia. The primary outcome of VAS scores at the time backward (T0), 4 h (T1), 12 h (T2), 24 h (T3), 48 h (T4) postoperatively and the amount of remedy for analgesic consumption within 48 h postoperatively were compared. The secondary outcome of adverse reactions and plasma concentrations of serotonin (5-HT) and substance P (SP) at T0, T1, T2, T3, T4 were detected, respectively. The VAS scores at T1, T2, T3, T4 postoperatively in two groups were lower than T0. Compared to group C, the VAS scores at T1 (3.68 ± 0.68 vs. 4.79 ± 0.82, P = 0.01), T2 (2.64 ± 0.72 vs. 3.92 ± 0.88, P = 0.03), T3 (2.21 ± 0.88 vs. 3.38 ± 0.74, P < 0.01) in Group T were lower, and total remedy of analgesic consumption was significantly lower (127.14 ± 28.46 vs. 415.27 ± 86.37, P < 0.01) within 48 h postoperatively. The plasma concentrations of 5-HT in Group T was lower than Group C at T1 (348.54 ± 138.49 vs. 418.69 ± 124.68, P = 0.03), T2 (324.28 ± 112.73 vs. 398.52 ± 114.53, P < 0.01), T4 (309.64 ± 129.09 vs. 388.46 ± 115.36, P = 0.04) postoperatively and concentrations of SP at T1 (59.38 ± 24.68 vs. 78.93 ± 26.32, P < 0.01), T2 (49.36 ± 25.55 vs. 66.49 ± 23.57, P = 0.02), T3 (42.19 ± 24.36 vs. 64.15 ± 28.16, P = 0.04), T4 (39.26 ± 19.88 vs. 54.64 ± 20.62, P = 0.02) postoperatively were also lower than Group C. Meanwhile, the occurrences of vertigo (6.7 vs. 18.3%, P < 0.01), nausea and vomiting (11.7 vs. 21.7%, P < 0.01), constipation (10.0 vs. 20.0%, P = 0.03) in Group T were also lower. Application of TEAS alone was associated with effective alleviation of postoperative pain, reduction of postoperative analgesics consumption, decrease of plasma concentration of algogenic substance and the incidence of adverse reactions after ureteroscopic lithotripsy.

Objective: To evaluate the effect of butorphanol on the prevention of myoclonus induced by etomidate. Materials and methods: We searched the PubMed, Embase, Cochrane Library, and China National Knowledge Infrastructure databases to collect relevant randomized controlled trials (RCTs) evaluating the effect of butorphanol on etomidate-induced myoclonus in January 2019 without any language restrictions. The primary outcome was the incidence of etomidate-induced myoclonus. Secondary outcomes included the incidence of myoclonus at various degrees and the incidence of adverse effects. Risk ratios (RRs) were calculated for binary outcomes. All statistical analysis were performed by using RevMan 5.3 software. Results: We identified 6 RCTs involving a total of 608 patients who reported the incidence of etomidate-induced myoclonus. In pooled analyses, the incidence of etomidate-induced myoclonus in the butorphanol group was significantly lower than that in the control group (RR =0.15, 95% CI [0.10, 0.22], P<0.00001). Subgroup analyses showed that butorphanol significantly decreased the numbers of patients with mild myoclonus (RR =0.41, 95% CI [0.25, 0.68], P=0.0005), moderate myoclonus (RR =0.18, 95% CI [0.09, 0.34], P<0.00001), and severe myoclonus (RR =0.04, 95% CI [0.01, 0.10], P<0.00001). Additionally, butorphanol did not increase the incidence of postoperative nausea/vomiting (RR =3.0, 95% CI [0.32, 28.42], P=0.34) or dizziness (RR =6.79, 95% CI [0.84, 54.84], P=0.07) associated with etomidate. Conclusion: Our findings suggest that butorphanol can effectively prevent the incidence of etomidate-induced myoclonus and alleviate the intensity of etomidate-induced myoclonus, without inducing postoperative nausea/vomiting and dizziness.

OBJECTIVE: To explore the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative analgesia of ureteroscopic holmium laser lithotripsy. METHODS: One hundred and twenty adult patients, American Association of Anesthesiologists (ASA) Class â or â ¡, scheduled to ureteroscopic holmium laser lithotripsy, were randomly assigned into an observation group and a control group, 60 cases in each one. The patients in the observation group were treated with TEAS for postoperative analgesia. TEAS was implemented at bilateral Shenshu (BL 23) and Yinlingquan (SP 9) at the time of back ward and postoperative 4 h, 8 h, 12 h. TEAS at 7:00, 11:00 and 15:00 at the above acupoints were used on the second and third days; while placebo (twice a day, 100 mg a time) was used. Tramadol hydrochloride tablets for postoperative analgesia were applied in the contnol group, twice a day, 100 mg a time, and electrode sheets without stimulation were put on Shenshu (BL 23) and Yinlingquan (SP 9). When analgesia was insufficient with the score of visual analogue scale (VAS)≥3, the patients were treated with tramadol tablets for remedy analgesia. The VAS score, the concentrations of serotonin (5-HT) and substance P (SP) in 3 mL venous blood at the time of back ward (T0), postoperative 4 h (T1), 12 h (T2), 24 h (T3), and 48 h (T4) were detected respectively. The total amount of medication for remedy analgesia and the incidence of adverse reactions, such as nausea and vomiting within postoperative 48 h were compared between the two groups. RESULTS: The VAS scores at T1 through T4 were lower than those at T0 in the two groups (all P<0.05). Compared with the control group, the VAS scores at T1 through T3 in the observation group were lower (all P<0.05). The total dose of remedy analgesic medicine within 48 h after operation in the observation group was lower than that in the control group (P<0.05). Compared with the control group, the concentrations of 5-HT at T1, T2, T4 and SP at T1 through T4 were lower (all P<0.05). The numbers of constipation, nausea and vomiting in the observation group were less than those in the control group (both P<0.05). CONCLUSION: TEAS can relieve the pain and reduce the total amount of analgesic medicine, the levels of substance causing pain and the incidence of adverse reactions after ureteroscopic holmium laser lithotripsy.

The immunological function of patients with malignant tumors may be suppressed during the perioperative period. However, details on the effects of transcutaneous electrical acupoint stimulation (TEAS) on immunological function are relatively lacking. We designed this study to examine the effects of TEAS on the immunological function of patients with non-small cell lung cancer (NSCLC) during the perioperative period. Participants (n = 144) were enrolled and randomly assigned into group TEAS or group sham TEAS. TEAS on bilateral Feishu (BL13), Hegu (L14), and Zusanli (ST36) was performed continuously throughout the procedure. The primary outcome was the quantities of natural killer (NK) cells at 30 minutes before induction (T0), 5 minutes after intubation (T1), at the beginning of the operation (T2), at the beginning of the lobectomy (T3), at the beginning of the lymphadenectomy (T4), and immediately after extubation (T5). The secondary outcomes were the serum levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) at T0 to T5, the mean arterial pressure (MAP) and heart rate (HR), the intraoperative consumption of propofol and remifentanil, the incidence of hypoxemia, postoperative nausea and vomiting (PONV), and the length of hospital stay. The quantities of NK cells were decreased in group sham TEAS after intubation compared to that in group TEAS, while the quantities of NK cells in group TEAS were similar at T0 to T5. Meanwhile, the quantities of NK cells in group sham TEAS at T1 ( P = .012), T2 ( P < .001), T3 ( P = .027), T4 ( P = .045), and T5 ( P = .021) were lower than those in group TEAS. In group TEAS, the serum levels of TNF-α were lower at T1 to T5, while the levels of IL-6 were lower at T2 to T5. Furthermore, the intraoperative MAP and HR were more stable, the total propofol and remifentanil consumptions were lower, and the length of hospital stay was shorter than those in group sham TEAS. The application of TEAS can effectively reverse the decrease in NK cells, decrease the serum levels of TNF-α and IL-6, maintain hemodynamic stability during the perioperative period, decrease the consumption of propofol and remifentanil, and shorten the length of the hospital stay.
