OBJECTIVETo explore the effectiveness and safety of transcutaneous electrical acupoint stimulation (TEAS) combined with infusion of propofol in anodynia bronchoscopy.

METHODSNinety patients who received selective bronchoscopy were randomized into a group of compound TEAS with infusion of propofol (group A), a group of compound fentanyl with propofol (group B) and a group of simple propofol (group C). In group A, the plaster electrode stimulation was applied at bilateral Hegu (LI 4), Laogong (PC 8), Neiguan (PC 6) and Waiguan (TE 5). The anesthesia was induced after 20 min of stimulation till the end of examination. In group B and group C, the electric stimulation was not adopted. In group B, before anesthesia, fentanyl 1 microg/kg was injected intravenously. Afterwards, the intravenous infusion of propofol was used in the the three groups for anesthesia. The mean arterial pressure (MAP), heart rate (HR), saturation of pulse oximetry (SpO2) and respiratory rate (RR) were recorded at different time points. The induced dosage and total dosage of propofol, examination time, the awakening time and adverse reactions were observed in the patients of each group.

RESULTSThe difference in examination time was not significant among the three groups (P > 0.05). The postoperative awakening time in group A was earlier than that in group B and group C [(220.3 +/- 110.5) s vs (285.6 +/- 109.4) s, (290.1 +/- 105.1) s, both P < 0.05]. The total dosage of propofol in group C was larger than those in group A and group B [(288.5 +/- 26.7) mg vs (225.1 +/- 30.2) mg, (230.4 +/- 29.3) mg, both P < 0.05]. The induced dosage in group C was larger than those in group A and group B [(193.7 +/- 42.3) mg vs (152.3 +/- 36.1) mg, (155.4 +/- 40.5) mg, both P < 0.05]. Every life physical sign in group A during examination was more stable as compared with that in group B and group C. The incidence of hypotension and bradycardia in group A were lower than those in group C [3.3% (1/30) vs 26.7% (8/30), 0% (0/30) vs 20.0% (6/30), both P < 0.05]. The adverse incidence of oxygen supply in group A was lower than that in group B [6.7% (2/30) vs 33.3% (10/30), P < 0.05]. Intraoperative awareness and improper memory did not happen in postoperative investigation.

CONCLUSIONIn the transcutaneous electrical acupoint stimulation combined with infusion of propofol in anodynia bronchoscopy, the physical sign of patient is stable with less adverse reactions. This method reduces anesthetic dosage and shortens the postoperative awakening time, which can be effectively applied in bronchoscopy.

Objective:To investigate the value of bedside transthoracic echocardiography(TTE) in volume reactivity assessment of children with septic shock.Methods:A total of 41 children aged from 1 to 5 years with septic shock requiring mechanical ventilation admitted to PICU from January 2017 to June 2020 were prospectively included.Under the condition of complete mechanical ventilation, full sedation and analgesia, and no spontaneous breathing(tidal volume 8 to 10 mL/kg), volume expansion was given to children.Hemodynamic indexs such as cardiac index(CI), stroke volume index(SVI) and stroke volume variability(SVV) were measured before and after volume expansion by noninvasive cardiac output monitoring(NICOM) and TTE.Moreover, aortic flow velocity time integral variable degrees(ΔVTI), inferior vena cava variability(ΔIVC) and inferior vena cava dilation index(dIVC) were also measured by TTE.Patients were considered to be responsive to volume expansion if SVI NICOMincreased≥15%.Based on the responsiveness of volume expansion, all the patients were divided into response group and non-response group.The value of SVV TTE, ΔVTI, ΔIVC, dIVC, ΔCVP and SVV NICOMin predicting volume responsiveness were analysed. Results:(1) There were 23 cases in response group and 18 cases in non-response group.Before volume expansion, there were no statistically significant differences in general hemodynamic indexes HR, MAP, CVP, EF, CI NICOM, and CI TTEbetween two groups( P>0.05). (2) In response group, HR, MAP, CI, SVI and CVP were all improved after volume expansion( P<0.001). In non-response group, only CVP was significantly increased after volume expansion, while other indexes were not improved( P>0.05). (3)Before the volume expansion, SVV TTE, ΔVTI, ΔIVC, and dIVC in response group were higher than those in non-response group( P<0.001). After volume expansion, these indicators were significantly reduced in response group.In non-response group, only ΔIVC significantly reduced after volume expansion.(4) The receiver-operating characteristic curve analysis showed that the area under the curve of SVV TTEand ΔVTI was 0.971, with 12.04% as the threshold, the sensitivity was 0.957 and the specificity was 0.944. The area under the curve of ΔIVC was 0.981, with 25.98% as the threshold, the sensitivity was 0.870 and the specificity was 1.000.The area under the curve of dIVC was 0.980, with 29.86% as the threshold, the sensitivity was 0.870 and the specificity was 1.000. The area under the curve of ΔCVP was 0.778, with 2.5 cmH 2O(1 cmH 2O=0.098 kPa) as the threshold, the sensitivity was 0.913 and the specificity was 0.556. The area under the curve of SVV NICOMwas 0.874, with 12.50% as the threshold, the sensitivity was 0.869 and the specificity was 0.778. Conclusion:The dynamic indexes SVV, ΔVTI, ΔIVC and dIVC monitored by TTE have good accuracy in evaluating children′s volume responsiveness, among which the accuracy of ΔIVC and dIVC is relatively the highest; the value of ΔCVP in predicting volume responsiveness is limited.

Objective:To observe the effects of continuous light exposure on skeletal muscle fiber type transformation and lipid metabolism, and to explore its internal relationship.Methods:Mice were randomly divided into normal light group and 24-hour continuous light group by random number table. The serum and skeletal muscle lipid content and urine 6-sulfatoxymelatonin(6-SML)level were detected by ELISA. The expression of circadian clock and lipid metabolism related genes mRNA were observed by realtime PCR. The muscle fiber type and lipid deposition were evaluated by tissue immunofluorescence as well as oil red O staining.Results:Compared with the normal light group, the level of 6-SML in urine at night decreased( P<0.05), and the expression level and rhythm of brain and muscle ARNT-like protein 1(Bmal1), circadian locomotor output cycles protein kaput(Clock), and period 2(Per2)mRNA in the skeletal muscle changed in continuous light group. In addition, the body weight, blood lipid, free fatty acid, and triglyceride contents of skeletal muscle in continuous light group increased significantly( P<0.05 or P<0.01), the expression of carnitine palmitoyltransferase 1b (Cpt1b)mRNA, the key enzyme of fatty acid oxidation, decreased significantly( P<0.05), while the expression of stearoyl-CoA desaturase(Scd1)mRNA, a lipid synthesis related gene, increased significantly( P<0.01). Further immunofluorescence analysis showed that the proportion of slow muscle fibers decreased and that of fast muscle fibers increased in continuous light group(both P<0.05). Conclusion:The process of ectopic deposition of lipid in skeletal muscle in mice induced by continuous light exposure may be related to the remodeling of skeletal muscle fibers.

OBJECTIVETo observe the therapeutic effect of Wenshen Huatan Recipe (WHR) on patients with early or middle stage chronic renal insufficiency (CRI) and investigate the clinical validity of applying sputum and blood stasis theory in treating CRI.

METHODSSixty CRI patients were selected and randomly assigned to the treated group (n = 32) and the control group (n = 28), all received conventional and symptomatic treatment, but those in the treated group were given WHR additionally. Two months were taken as one treatment course and the study lasted for 3 treatment courses. Total effective rate was assessed at the end of the 2nd and 6th month, changes of clinical symptom scores of TCM, and levels of blood urea nitrogen (BUN) and serum creatinine (SCr) in the two groups were observed as well.

RESULTSThe total effective rate of the 2nd and 6th month was 68.8% and 75.0% respectively in the treated group and 42.9% and 35.7% in the control group respectively, the difference between the two groups was significant (P < 0.05). Symptoms were improving along with the increasing medication time, and the improvement between the two groups was significant (P<0.01). Levels of SCr and BUN were significantly lowered in the treated group after 2-month and 6-month treatment (P < 0.05, P < 0.01).

CONCLUSIONWHR can significantly improve the clinical effect of treatment on CRI during early-middle stage, suggesting that CRI could be treated based on sputum and blood stasis theory with definite clinical efficacy.
