Electroacupuncture in Treatment of Acute Gastrointestinal Injury in Patients with Severe Traumatic Brain Injury: A Multicenter Randomized Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To evaluate whether electroacupuncture (EA) would improve gastrointestinal function and clinical prognosis in patients with severe traumatic brain injury (TBI) complicocted by acute gastrointestinal injury (AGI).@*METHODS@#This multicenter, single-blind trial included patients with TBI and AGI admitted to 5 Chinese hospitals from September 2018 to December 2019. A total of 500 patients were randomized to the control or acupuncture groups using a random number table, 250 cases in each group. Patients in the control group received conventional treatment, including mannitol, nutritional support, epilepsy and infection prevention, and maintenance of water, electrolytes, and acid-base balance. While patients in the acupuncture group received EA intervention at bilateral Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), Tianshu (ST 25), and Zhongwan (RN 12) acupoints in addition to the conventional treatment, 30 min per time, twice daily, for 7 d. The primary endpoint was 28-d mortality. The secondary endpoints were serum levels of D-lactic acid (D-lac), diamine oxidase (DAO), lipopolysaccharide (LPS), motilin (MTL) and gastrin (GAS), intra-abdominal pressure (IAP), bowel sounds, abdominal circumference, AGI grade, scores of gastrointestinal failure (GIF), Glasgow Coma Scale (GCS), Acute Physiology and Chronic Health Evaluation (APACHE II), Sequential Organ Failure Assessment (SOFA), and Multiple Organ Dysfunction Syndrome (MODS), mechanical ventilation time, intense care unit (ICU) stay, and the incidence of hospital-acquired pneumonia.@*RESULTS@#The 28-d mortality in the acupuncture group was lower than that in the control group (22.80% vs. 33.20%, P<0.05). Compared with the control group, the acupuncture group at 7 d showed lower GIF, APACHE II, SOFA, MODS scores, D-lac, DAO, LPS, IAP, and abdominal circumference and higher GCS score, MTL, GAS, and bowel sound frequency (all P<0.05). In addition, the above indices showed simillar changes at 7 d compared with days 1 and 3 (all P<0.05) in the EA group.@*CONCLUSION@#Early EA can improve gastrointestinal function and clinical prognosis in patients with severe TBI complicated by AGI.

The Anterior Insula and its Projection to the Prelimbic Cortex are Involved in the Regulation of 5-HT-Induced Itch / 神经科学通报·英文版

Itch is an unpleasant sensation that urges people and animals to scratch. Neuroimaging studies on itch have yielded extensive correlations with diverse cortical and subcortical regions, including the insular lobe. However, the role and functional specificity of the insular cortex (IC) and its subdivisions in itch mediation remains unclear. Here, we demonstrated by immunohistochemistry and fiber photometry tests, that neurons in both the anterior insular cortex (AIC) and the posterior insular cortex (PIC) are activated during acute itch processes. Pharmacogenetic experiments revealed that nonselective inhibition of global AIC neurons, or selective inhibition of the activity of glutaminergic neurons in the AIC, reduced the scratching behaviors induced by intradermal injection of 5-hydroxytryptamine (5-HT), but not those induced by compound 48/80. However, both nonselective inhibition of global PIC neurons and selective inhibition of glutaminergic neurons in the PIC failed to affect the itching-scratching behaviors induced by either 5-HT or compound 48/80. In addition, pharmacogenetic inhibition of AIC glutaminergic neurons effectively blocked itch-associated conditioned place aversion behavior, and inhibition of AIC glutaminergic neurons projecting to the prelimbic cortex significantly suppressed 5-HT-evoked scratching. These findings provide preliminary evidence that the AIC is involved, at least partially via aversive emotion mediation, in the regulation of 5-HT-, but not compound 48/80-induced itch.

Benefits of Mindfulness Training on the Mental Health of Women During Pregnancy and Early Motherhood: A Randomized Controlled Trial / 生物医学与环境科学（英文）

OBJECTIVE@#This study aimed to evaluate the effects of a mindfulness-based psychosomatic intervention on depression, anxiety, fear of childbirth (FOC), and life satisfaction of pregnant women in China.@*METHODS@#Women experiencing first-time pregnancy ( n = 104) were randomly allocated to the intervention group or a parallel active control group. We collected data at baseline (T0), post-intervention (T1), 3 days after delivery (T2), and 42 days after delivery (T3). The participants completed questionnaires for the assessment of the levels of depression, anxiety, FOC, life satisfaction, and mindfulness. Differences between the two groups and changes within the same group were analyzed at four time points using repeated-measures analysis of variance.@*RESULTS@#Compared with the active control group, the intervention group reported lower depression levels at T2 ( P = 0.038) and T3 ( P = 0.013); reduced anxiety at T1 ( P = 0.001) and T2 ( P = 0.003); reduced FOC at T1 ( P < 0.001) and T2 ( P = 0.04); increased life satisfaction at T1 ( P < 0.001) and T3 ( P = 0.015); and increased mindfulness at T1 ( P = 0.01) and T2 ( P = 0.006).@*CONCLUSION@#The mindfulness-based psychosomatic intervention effectively increased life satisfaction and reduced perinatal depression, anxiety, and FOC.

Objective: To explore the epidemiological characteristics and treatment outcomes of patients with hydrofluoric acid burns in hands. Methods: A retrospective observational study was conducted. The medical records of 229 patients with hydrofluoric acid burns in hands who were admitted to Zhejiang Quhua Hospital from January 2008 to December 2020 and met the inclusion criteria were collected. The following statistical data of patients were collected, including gender, age, type of affiliated enterprise, hydrofluoric acid mass fraction, injury site, total burn area, prehospital time, length of hospital stay, length of wound healing, whether hypocalcemia and hypomagnesemia occurred or not on admission, whether surgery intervention was performed or not, and whether scar sequelae occurred or not. Single factor and multivariate logistic regression analysis were used to screen out the risk factors impacting surgery intervention and scar sequelae of all the patients and patients whose hydrofluoric acid mass fraction was known. Single factor and multivariate linear regression analysis were used to screen out the risk factors impacting the length of wound healing of all the patients and patients whose hydrofluoric acid mass fraction was known. Results: The 229 patients included 206 males and 23 females, with the majority aged 30 to 50 years (139 patients). The type of affiliated enterprise of majority patients was non-fluorine chemical enterprise. The hydrofluoric acid mass fraction was known in only 91 patients, mainly medium. The majority injury site was in the middle and end of finger. The total burn area was below or equal to 1% total body surface area. The prehospital time was 19 (9, 29) h. The length of hospital stay was 2 (1, 7) d. The length of wound healing was 12 (8, 18) d. The proportions of hypocalcemia and hypomagnesemia were 0.9% (2/229) and 1.3% (3/229) on admission, respectively. Thirty-six patients had surgeries and 83 patients had scar sequelae. In 229 patients, single factor logistic regression analysis showed that both type of affiliated enterprise and prehospital time were the factors impacting surgery intervention (with odds ratio values of 7.86 and 51.35, respectively, 95% confidence intervals of 1.83-33.76 and 11.89-221.78, respectively, P<0.01) and scar sequelae of patients (with odds ratio values of 3.62 and 27.40, respectively, 95% confidence intervals of 1.76-7.43 and 13.25-56.68, respectively, P<0.01); multivariate logistic regression analysis showed that prehospital time was the independent risks factor impacting surgery intervention and scar sequelae of patients (with odds ratio values of 43.00 and 24.55, respectively, 95% confidence intervals of 9.89-187.03 and 11.78-51.16, respectively, P<0.01); single factor linear regression analysis showed that both type of affiliated enterprise and prehospital time were the factors impacting the length of wound healing of patients (with β values of 6.16 and 12.83, respectively, 95% confidence intervals of 3.38-8.93 and 10.72-14.93, respectively, P<0.01); multivariate linear regression analysis showed that both type of affiliated enterprise and prehospital time were the independent risk factors impacting the length of wound healing of patients (with β values of 2.81 and 12.16, respectively, 95% confidence intervals of 0.50-5.13 and 10.00-14.31, respectively, P<0.05 or P<0.01). In 91 patients whose hydrofluoric acid mass fraction was known, single factor logistic regression analysis showed that type of affiliated enterprise, hydrofluoric acid mass fraction (low and high), and prehospital time were all the factors impacting surgery intervention of patients (with odds ratio values of 9.10, 11.25, 10.69, and 0.04, respectively, 95% confidence intervals of 1.15-72.25, 1.39-90.93, 1.32-86.59, and 0.01-0.19, respectively, P<0.05 or P<0.01), type of affiliated enterprise, hydrofluoric acid mass fraction, and prehospital time were all the factors impacting scar sequelae of patients (with odds ratio values of 0.32, 0.21, and 36.80, respectively, 95% confidence intervals of 0.11-0.92, 0.06-0.73, and 11.03-122.79, respectively, P<0.05 or P<0.01); multivariate logistic regression analysis showed that both hydrofluoric acid mass fraction and prehospital time were the independent risk factors impacting surgery intervention of patients (with odds ratio values of 11.51 and 0.04, respectively, 95% confidence intervals of 1.22-108.26 and 0.01-0.25, respectively, P<0.05 or P<0.01), prehospital time was the independent risk factor impacting scar sequelae of patients (odds ratio=37.71, with 95% confidence interval of 9.97-142.69, P<0.01); single factor linear regression analysis showed that type of affiliated enterprise, hydrofluoric acid mass fraction (low and high), and prehospital time were all the factors impacting the length of wound healing of patients (with β values of 7.12, -5.63, -9.74, and 13.50, respectively, 95% confidence intervals of 2.43-11.81, -10.59--0.68, -14.78--4.70, and 10.14-16.86, respectively, P<0.05 or P<0.01); multivariate linear regression analysis showed that both hydrofluoric acid mass fraction and prehospital time were the independent risk factors impacting the length of wound healing of patients (with β values of -5.84 and 0.09, respectively, 95% confidence intervals of -10.59--1.08 and 0.05-0.12, respectively, P<0.05 or P<0.01). Conclusions: The majority of patients with hydrofluoric acid burns in hands are young and middle-aged males. Type of affiliated enterprise, hydrofluoric acid mass fraction and prehospital time are the risk factors that affect the treatment outcomes of patients with hydrofluoric acid burns in hands.

Electroacupuncture in the treatment of acute gastrointestinal injury in patients with severe traumatic brain injury: a prospective randomized controlled trial / 中华危重病急救医学

Objective:To evaluate the therapeutic effect of electroacupuncture on acute gastrointestinal injury (AGI) in patients with severe traumatic brain injury (sTBI).Methods:A prospective randomized controlled trial was conducted. 126 consecutively hospitalized patients with AGI after sTBI admitted to intensive care unit (ICU) of the First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from January 2018 to December 2019 were enrolled. The patients were divided into observation group and control group by random number table. All the patients of two groups were given conventional treatment of western medicine for consecutive 7 days, including the treatments of primary diseases, indwelling nasogastric tube to extract gastric contents every 6 hours to determine gastric residual volume (GRV). When vital signs were basically stable, enteral nutrition (EN) was implemented and EN feeding amount and speed were adjusted according to GRV. On the basis of conventional western medicine treatment, the observation group was treated with electroacupuncture at Zusanli, Tianshu, Shangjuxu, Xiajuxu and Zhongwan, once in the morning and once in the evening, 30 minutes each time. The gastrointestinal function parameters including intra-abdominal pressure (IAP), serum diamine oxidase (DAO) and gastrointestinal failure (GIF) scores were observed before treatment and at day 3 and day 7 of treatment. The incidence of ICU hospital-acquired pneumonia (HAP-ICU), duration of mechanical ventilation (MV), length of ICU stay, 28-day mortality and adverse reactions of electroacupuncture were also observed in the two groups. Kaplan-Meier method was used for 28-day survival analysis.Results:During the 7-day treatment and observation, 26 cases of 126 patients withdrew from the study, and 100 cases were actually enrolled, 50 cases in the observation group and 50 cases in the control group. IAP and DAO at day 3 of treatment in both groups were significantly lower than those before treatment [control group: IAP (cmH 2O, 1 cmH 2O = 0.098 kPa) was 13.75±2.76 vs. 18.11±3.97, DAO (U/L) was 129.88±24.81 vs. 158.01±22.64; observation group: IAP (cmH 2O) was 13.56±2.19 vs. 18.50±3.54, DAO (U/L) was 129.11±29.32 vs. 159.36±28.65; all P < 0.01]. The gastrointestinal function parameters of the two groups improved gradually with the extension of treatment time, and the IAP, DAO and GIF scores at day 7 of treatment in the observation group were significantly lower than those in the control group [IAP (cmH 2O): 11.28±3.61 vs. 12.68±3.23, DAO (U/L): 49.69±17.56 vs. 57.27±20.15, GIF score: 2.02±0.74 vs. 2.40±0.70, all P < 0.05). The duration of MV and the length of ICU stay in the observation group were significantly shorter than those in the control group [duration of MV (days): 15.72±4.60 vs. 18.08±4.54, length of ICU stay (days): 16.76±4.68 vs. 19.26±5.42, both P < 0.05], and the incidence of ICU-HAP and 28-day mortality were significantly lowered (12.0% vs. 30.0%, 22.0% vs. 32.0%, both P < 0.05). Survival analysis showed that the 28-day cumulative survival rate in the observation group was significantly higher than that in the control group (86.4% vs. 76.1%; Log-Rank test: χ 2 = 37.954, P < 0.001). The patients in the observation group had no significant adverse reaction of electroacupuncture treatment. Conclusion:Electroacupuncture at corresponding acupoints can effectively improve gastrointestinal function in patients with AGI after sTBI, which is beneficial to shortening the length of ICU stay, promoting the recovery of the patients, and reducing the 28-day mortality.

Systemic air embolism in a fungal pneumonia patient with lung cavities formation and review of literature / 中华创伤杂志(英文版)

Systemic air embolism is a rare but potentially fatal complication related to many factors. The purpose of this article is to alert clinicians once patients occurs an abnormal neurological and cardiovascular status, following minor traumatic treatment, air embolism should be considered. A 20-year-old man who presented with fungal pneumonia with lung cavities formation was admitted to an intensive care unit (ICU) and received positive airway pressure ventilation. Four days later, the fungal pneumonia was improved, but the patient's blood pressure and arterial oxygen saturation deteriorated, so computed tomography (CT) scans were preformed to reevaluate him. The scans detected air embolism in the left atrium and ventricle, ascending aorta, aortic arch and its branches (right brachiocephalic, bilateral common carotid and right subclavian arteries), descending aorta and right coronary artery. A CT scan of the abdomen revealed air in the spleen, cauda pancreatic, superior mesenteric artery and right external iliac artery. The patient died two days later from multiple organ dysfunction. We suggest that vascular air embolism should be considered under mechanical ventilation when patients' neurologic and cardiovascular status deteriorates, and hyperbaric oxygen therapy should be conducted immediately.

Effect of Tanshinone ⅡA injection on intestinal mucosal tight junction protein in severe rat septic models / 中国中西医结合急救杂志

Objective To discuss the influence of Tanshinone ⅡA on the tight junction protein of intestinal mucosal epithelial cells in rat severe septic models. Methods Seventy-five Sprague-Dawley (SD) rats were randomly divided into sham operation group, model group and Tanshinone ⅡA injection high (20 mg/kg), medium (10 mg/kg) and low (5 mg/kg) dose groups, each group 15 rats. Sepsis rat models were established by cecal ligation and puncture (CLP) method, in sham operation group, only switched abdominal surgery was performed without CLP. In Tanshinone ⅡA injection groups, different doses of Tanshinone ⅡA were injected intraperitoneally after modeling for 10 minutes and 6 hours; in sham operation and model groups, equal volume of normal saline was injected intraperitoneally at the same times as above. After operation, 3 L/kg of normal saline was injected into the caudal vein in all rats for fluid resuscitation.Twelve hours after operation, the rats were killed, the abdominal lymph nodes, liver, spleen and kidney tissues were taken for bacterial culture and calculating the rate of bacterial translocation; under microscope, the histopathological changes of ileum mucosal tissues were examined and Chiu scoring was carried out; TdT-mediated dUTP nick end labeling (TUNEL) was applied to detect the ileum mucosal epithelial cell apoptosis and calculating the index (AI);fluorescence immunoassay and Western Blot methods were used to measure the contents and protein expression levels of tight junction protein, junctional adhesion molecule-1 (JAM), Claudin-1, Zonula occludens-1 (ZO-1), Occludin, c-Fos and Tryptase. Results ① In bacterial cultures of abdominal lymph node, liver, spleen and kidney, the positive rate of mesenteric lymph node was the highest, followed by liver and spleen, mainly Escherichia coli, Proteus mirabilis, etc. The highest positive rate of bacterial culture was in model group (38.8%), followed by low dose of Tanshinone ⅡA injection group (35.0%), and the lowest was 16.6% in high dose Tanshinone ⅡA injection group, the differences being statistically significant in comparisons between any pair of groups (all P < 0.05). ② Pathological examination showed that the pathological changes of ileum mucosa were obvious and the Chiu score (4.17±0.98 vs. 0) and AI (11.70±2.87 vs. 2.17±0.80) in model group were significantly higher than those in sham group (all P < 0.05); with the increase of dosage of Tanshinone ⅡA injection, the pathological changes of rat ileum mucosa were improved gradually, the Chiu score and AI were decreased gradually, and the degrees of decrease in high dose Tanshinone ⅡA group were more significant than those in model group (Chiu score: 1.12±0.79 vs. 4.17±0.98, AI: 3.65±1.98 vs. 11.70±2.87, both P < 0.05).③ Immunofluorescence staining showed that the positive staining of protein JAM, ZO-1 and c-Fos were all green in color, Claudin-1, Occludin and Tryptase were all red in color, the localizations of all of them were in the cytoplasm, the protein expression of JAM, Claudin-1, ZO-1, Occludin from strong to weak in turn were Sham group, high, medium, low dose Tanshinone ⅡA group and model group, the expression of c-Fos, Tryptase from strong to weak in turn were model group, low, medium, high dose Tanshinone ⅡA group and Sham group. ④ Western Blot showed that the expressions of ileum tissue JAM, Claudin-1, ZO-1 and Occludin in model group were all significantly lower than those of the sham group, while the expressions of c-Fos, Tryptase were obviously higher than those of the sham group, with the increase of dosage of Tanshinone ⅡA, the expressions of JAM, Claudin-1, ZO-1 and Occludin were increased gradually and the protein expressions of c-Fos and Tryptase were gradually decreased, and the changes in high dosage group of Tanshinone ⅡA were more significant than those in low and moderate groups [JAM (gray value): 25.39±1.82 vs. 12.41±1.34, 19.45±1.66, Claudin-1 (gray value): 28.44±1.56 vs.17.26±1.46, 21.23±1.34, ZO-1 (gray value): 28.84±1.59 vs. 16.45±1.21, 24.22±1.46, Occludin (gray value): 25.49±1.63 vs. 13.34±1.45, 19.45±1.37, c-Fos (gray value):15.76±1.36 vs. 27.84±1.36, 21.22±1.73, Tryptase (gray value): 14.44±1.41 vs. 28.14±1.38, 22.32±1.57], all the above comparisons of different dosage groups were statistically significant (all P < 0.05). Conclusion Tanshinone ⅡA injection may improve intestinal wall structure and reduce bacterial translocation by improving the intestinal mucosal tight junction protein in sepsis model rats, and this effect is positively correlated to Tanshinone ⅡA dosage.

Protective Effect and Potential Mechanism of Astragalus Injection on Mucosa Epithelial Cells in Rats with Sepsis / 浙江中医药大学学报

Objective] To investigate the protective effect and potential mechanism of Astragalus injection on mucosa epithelial cells in rats with sepsis . [Methods] Thirty Sprague-Dawley rats were randomly divided into sham,model and Astragalus injection treatment groups with 10 rats in each group.Rat sepsis model was constructed by cecal ligation and puncture.Rats in the Astragalus injection treatment group received 800 mg·kg-1 of Astragalus injection at 15 minutes before and 6 hours after operation. Intestinal mucosa were harvested and frozen at -80℃ on post-operation 24 hours. Intestinal mucosa epithelial cell apoptosis was detected by TUNEL,while Bcl-2 and Bax levels were determined by real-time quantitative PCR(qPCR) and Western blot technique.[Results] The apoptosis indexes were 5.2±0.3,22.3±1.2 and 11.2±0.9 of sham,model and Astragalus injection treatment group,respectively. Apoptosis index in model group was significantly higher than that in sham group( P<0.05),while the apoptosis of mucosa epithelial cells was significantly attenuated after Astragalus injection treatment(P<0.05).In model group,the expression of Bcl-2 was lower than that of sham group,whereas the expression of Bax was higher than that in sham group(P<0.05).Astragalus injection treatment significantly lowered Bax level while elevated Bcl-2 expression, compared with model group(P<0.05). [Conclusion] Astragalus injection could suppress sepsis-induced apoptosis of mucosa epithelial cells via up-regulating Bcl-2 and down-regulating Bax.

Imported B3 genotype measles viruses were isolated from measles cases in the Chinese mainland / 病毒学报

We isolated and identified the genotypes and molecular characteristics of the imported B3 measles virus (MeV) in the Chinese mainland. The Vero/SLAM cell line was used to isolate the viruses. Reverse transcription-polymerase chain reaction was undertaken to amplify the 450 nucleotide acids of the 3-terminal of the nucleoprotein gene. A phylogenetic tree was constructed and similarities in homology assessed. Results suggested that the Shanghai isolates MVi/Shanghai. CHN/38. 13/02 [B3] and MVi/Shanghai. CHN/40. 13/02[B3] were clustered within the same genotype group as the World Health Organization (WHO) B3 genotype reference strain. The number of differences in nucleotide acids between the two Shanghai isolates was one. The homology of nucleotide acids between the Shanghai isolates and the WHO B3 genotype reference strain (MVi/Ibadan. NGA/0.97/1/B3) was 98%. Comparative results from the Measles Nucleotide Surveillance system suggested that the sequences of Shanghai isolates and the 2013 vi- ruses from Australia, Japan, Korea, Hong Kong China, Philippines and Iran were identical. This is the first time that the B3 genotype of MeV in the Chinese mainland has been isolated since 1993. These data can be used to create a "baseline" of genetic information for measles viruses in China, and help to trace the transmission of measles viruses in China and the rest of the world.

Effect of electro-acupuncture at zusanli (ST36) on the expression of ghrelin and HMGB1 in the small intestine of sepsis rats / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore the expression of Ghrelin and high mobility group protein B1 (HMGB1) in the serum and the intestinal tissue of sepsis model rats, and to evaluate the effect of electro-acupuncture (EA) at Zusanli (ST36) on the expression of HMGB1 and Ghrelin.</p><p><b>METHODS</b>Forty-eight male Wistar rats were randomly divided into four groups, i.e., the sham-operation (sham), the cecal ligation and puncture group (CLP), the CLP + EA at Zusanli (ST36) group (EA), and the CLP + Ghrelin receptor blocking agent + EA group (GHSRA), 12 in each group. A sepsis rat model was prepared by CLP. The incision of the abdominal wall was immediately sutured along the ventral midline for rats in the Sham group. In the EA group EA at Zusanli (ST36) was performed 20 min after CLP surgery with the constant voltage (2 - 100 Hz, 2 mA) for 30 min. In the GHSRA group, Ghrelin receptor blocking agent, [D-Arg1, D-Phe5, D-Trp79, Leu11]-substance P (700 nmol/kg), was administered through intravenous injection immediately after CLP, and 20 min later, EA at Zusanli (ST36) was performed in the same way as for rats in the EA group. Blood samples were withdrawn 12 h after CLP. The serum levels of Ghrelin and HMGB1 were detected using ELISA. Ghrelin expressions and the number of Ghrelin immunopositive cell in the jejunum were determined by immunohistochemistry. HMGB1 contents of the jejunum tissue were detected by Western blotting.</p><p><b>RESULTS</b>Compared with the Sham group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly increased and levels of Ghrelin and the expression rate of immunopositive cells significantly decreased in the CLP group (P < 0.05). Compared with the CLP group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly decreased, but levels of Ghrelin and the expression rate of immunopositive cells significantly increased in the EA group (P < 0.05). Compared with the EA group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly increased in the GHSRA group (P < 0.05), but there was no statistical difference in levels of Ghrelin between the two groups (P > 0.05). The serum level of HMGB1 was negatively correlated with Ghrelin in the Sham group, the CLP group, and the EA group (r = -0. 528, P < 0.01).</p><p><b>CONCLUSIONS</b>EA at Zusanli (ST36) could inhibit the expression of HMGB1 in the jejunum of septic rats, and promote the expression of Ghrelin. The expression of HMGB1 was inhibited by Ghrelin receptor blocking agent, which suggested that the anti-inflammation of EA at Zusanli (ST36) might be associated with Ghrelin.</p>

Impacts of electroacupuncture on intestinal permeability in sepsis patients / 中国针灸

<p><b>OBJECTIVE</b>To observe the efficacy of electroacupuncture on sepsis and explore its mechanism.</p><p><b>METHODS</b>Fifty cases were randomized into an observation group (26 cases) and a control group (24 cases). The therapeutic programs of anti-infection, anti-shock, respiratory support and nutritional support were provided, but the drugs that might affect gastrointestinal motility were not prescribed in two groups. In the observation group, on the basic treatment as above, electroacupuncture was applied to Zusanli (ST 36), Tianshu (ST 25), Shangjuxu (ST 37), Xiajuxu (ST 39). The excretion ratio of lactulose to mannitol (L/M) in urine and serum D-lactic acid level were detected before and after treatment, as well as the time of target feeding of the patients in two groups. The efficacy was compared between two groups.</p><p><b>RESULTS</b>After treatment for 3 days, L/M was (0.083 +/- 0.020) and serum D-lactic acid was (0.155 +/- 0.196) mmol/L in the observation group, which were apparently reduced as compared with (0.123 +/- 0.034) and (0.193 +/- 0.377) mmol/L in the control group respectively (both P < 0.05). The time of target feeding was (93.69 +/- 27.58) h in the observation group, which was shortened apparently than (118.17 +/- 40.28) h in the control group (P < 0.05). The total effective rate was 80.8% (21/26) in the observation group, which was better than 54.2% (13/24) in the control group (P < 0.05).</p><p><b>CONCLUSION</b>Conventional treatment combined with electroacupuncture can improve intestinal permeability in sepsis patients, recover intestinal function as quickly as possible to achieve target feeding.</p>

Effects of pneumonia caused by klebsiella pneumoniae on apoptosis of thymocytes in rats / 中华急诊医学杂志

Objective To study the effects of pneumonia caused by Klebsiella pneumoniae on apoptosis of thymocytes in rats and its possible mechanism. Methods A total of 48 Sprague Dawley rats were randomly (random number) divided into 2 groups, namely the control group (n =24) and the infection group ( n = 24). The pneumonia models of rats were made with 0.3 mL Klebsiella pneumoniae suspension administered intratracheally per animal. On the 2nd, 4th, and 6th day after intratracheal instillation of bacteria, 1/ 3 of the rats in each group were sacrificed and TdT-mediated dUTP nick end labeling (TUN EL) method was used to assess the apoptosis of thymocytes. The expressions of cleaved Caspase-3, Bcl-2 and Fas in thympcytes of rats were detected with immunohistochemical staining. Results On each interval, apoptosis index of thymocytes, and the expressions of Cleaved Caspase-3 and Fas in the infection group were all higher than those in the control group (P < 0.01) , while the expressions of Bcl-2 lower than those in the control group (P<0.01). As more time consumed, the apoptotic index of thymocytes and the expressions of cleaved Caspase-3 in the infection group increased significantly (P<0.05). The expressions of Bcl-2 declined gradually (P < 0.05), but the expressions of Fas reached their peak 4th day after infection. There were no significant dynamic changes in all above mentioned variables in control group. Conclusions Pneumonia caused by Klebsiella Pneumoniae can lead to the increase in thymocyte apoptosis in rats. The mechanism may be associated with the decreased expression of Bcl-2 and the increased expression of Fas in thymocytes of rats with pneumonia caused by Klebsiella pneumoniae. The different apoptosis regulation pathways have different effects on different phase of pneumonia, that the effects of Fas decrease 4th day after pneumonia, while the effects of Bcl-2 increase further.

Mechanism ud protection of electro-acupuncture at Zusanli points(足三星穴) on the apoptosis of thymocytes in rats with severe abdominal infection / 中国中西医结合急救杂志

Objective To study the influence of electro-acupuncture(EA)at Zusanli points(足三里穴) on the apoptosis of thymocytes in rats with abdominal infection and its mechanism.Methods A total of 40 Sprague-Dawley(SD)rats were randomly divided into four groups,including normal control group,model group,non-acupoint group and Zusanli group.The abdominal infection model of rat was made by cecal ligation and puncture(CLP).After abdominal cavity infection for 36 hours,the apoptosis of thymocytes was observed under electron microscope and light microscope,and the apoptosis ratio of thymocytes was determined by Annexin V-PI method with flow cytometry technique.The content of Bcl-2 protein of thymocytes and concentration of corticosterone in plasma were determined.Results Abdominal infection resulted from CLP could significantly increase the apoptosis of thymocytes and lead to the typical histopathological changes of apoptosis of thymocytes under electron microscope and light microscope.Apoptosis ratios of thyrnocytes in model group[(44.7?3.3)%],non-acupoint group[(42.7?3.0)%]and Zusanli group[(32.6?3.3)%] were significantly higher than the ratio in the control group[(21.2?2.3)%,all P0.05).Abdominal infection resulted from CLP also could reduce the content of Bcl-2 protein of thymocytes.The content of Bcl-2 protein of thymocytes in model group(71.2?5.6),non-acupoint group(73.5?5.9)and Zusanli group(82.4?6.8) were significantly lower than normal control group(95.3?6.3,all P
