Objective To investigate the role of NMDA receptors in central medial thalamus (CMT) in the unconscious?ness induced by general anesthesia. Methods A total of 60 rat models for microinfusion were assigned into 4 groups (n=15 for each group). After induction with propofol, 10 mmol/L (NMDA10 group), 20 mmol/L (NMDA 20 group) and 40 mmol/L (NMDA40 group) of NMDA and normal saline (group C) with equal volume were microinfused into CMT. The incidence of purposeful movement and recovery time of righting reflex were observed in each group respectively. Infusion sites were local?ized by histological method. Results When the microinfusion site localized within CMT, comparing with group C, the recov?ery time of righting reflex reduced notably in three NMDA groups (P<0.05). The recovery time was significantly shorter in NMDA20 group and NMDA40 group than that of NMDA10 group. The incidence of purposeful movement during propofol an?esthesia was higher in NMDA20 group and NMDA40 group than that of group C (P<0.05). When the microinfusion site lo?calized out of CMT, the recovery time of righting reflex was remarkably longer than that within CMT in three NMDA groups (P<0.05), and there was no significant difference in the incidence of purposeful movement and recovery time between four group (P>0.05). Conclusion Microinfusion of NMDA agonist into CMT reverses propofol anesthesia, indicating that NMDA receptor in CMT may contribute to the propofol-induced unconsciousness.

OBJECTIVE:To explore the regularity and characteristics of anaphylactoid reactions induced by Magnesium iso-glycyrrhizinate injection,and provide reference for clinical rational drug use. METHODS:27 ADR reports induced by Magnesium isoglycyrrhizinate injection from Hunan Center for ADR Monitoring from Jan. 2014 to Mar. 2015 were retrospectively analyzed. RE-SULTS:In the 27 cases,15 were male (55.56%) and 12 were female (44.44%),with percentage of 1.25∶1;ADR mainly oc-curred in patients with 41-60 years old(51.85%);involved organ/system were mainly skin and its appendages(35.85%)and sys-temic damage(26.42%),the main clinical manifestations were rash,itching,fever,chills,vomiting and dizziness;there were 7 severe ADR reports(25.92%),mainly showed chills,fever and other systemic symptoms;most ADR can be cured(40.74%)or relieved(55.56%)by related processing. CONCLUSIONS:There are no risk tips for severe allergic reactions in instruction,it is necessary to strengthen post-marketing surveillance and further improve the drug instructions to reduce the risk of severe ADR in-duced by Magnesium isoglycyrrhizinate injection.

Hemodynamic monitoring is an essential part in the care of children with congenital heart disease during perioperative period to guide clinical management.Currently,there are several methods available for hemodynamic monitoring.The invasive methods include the Fick method,thermodilution method,using the Swan-Ganz catheter and the pulse contour method.The noninvasive methods include partial carbon dioxide resorption,impedance method.In this paper,the principle,advantages and disadvantages of these monitoring methods in children undergoing cardiopulmonary bypass surgery were reviewed.

OBJECTIVE: To determine the expression of palate, lung, and nasal epithelial clone (PLUNC) in na sal polyps (NP) and evaluate its association with clinical severity. METHOD: Twenty-eight NP patients (primary polyp, 15; recurrent polyp, 13) and 16 normal controls (healthy uncinate process) were enrolled, the expression of PLUNC was examined in nasal tissues by immunohistochemistric staining, quantitative PCR and ELISA respectively. The protein level of PLUNC in nasal polyps was correlated with nasal symptom score (nasal congestion and rhinorrhea, respectively). RESULT: PLUNC was mainly distributed in the epithelial layer and submucosal glands in nasal tissues. The staining intensity and mRNA level of PLUNC were significantly decreased in polyp tissues than in normal controls (P < 0.01). The protein levels of PLUNC were 0.33 +/- 0.11 and 0.15 +/- 0.05 in primary and recurrent polyp tissues (P < 0.01), and were 0.32 +/- 0.14 and 0.19 +/- 0.07 in small-size and big-size polyp tissues (P < 0.05). The protein level of PLUNC in polyp tissues significantly correlated with both nasal congestion score and rhinorrhea score (r = -0.51 and r = -0.57, P < 0. 01). CONCLUSION Decreased PLUNC in polyp tissues indicated that impaired innate immunity may account for the pathogenic process of NP. Thus upregulating PLUNC may represent a promising therapeutic target for the management of NP.

Objective:To observe the clinical effect of electroacupuncture (EA) at four sacral points on overactive bladder syndrome.Methods:A total of 120 female patients with overactive bladder syndrome were allocated to a treatment group of 80 cases and a control group of 40 cases on a voluntary basis.The patients in the treatment group received EA at four sacral points,and the treatment was given three times a week for 6 consecutive weeks,while the patients in the control group received oral administration of M-receptor antagonist tolterodine tartrate,which was given 4 mg each time,once a day for 6 consecutive weeks.Then the symptom scores were compared between the two groups before and after treatment.Results:At the end of treatment,the symptom scores showed statistical significant differences in comparing with those before treatment in both groups (both P＜0.01);the symptom score in the treatment group was lower than that in the control group,showing a statistically significant difference (P＜0.05).Conclusion:EA at four sacral points is an effective method for overactive bladder syndrome.

Objedtve To summarize the experience of single-stage repair of coarctation of aorta(CoA) or interrupted aortic arch (IAA)and associated intracardiac defects through median stemotomy.Methods From Jan 2007 to Jul 2008,a total of 24 pa-tients with CoA or IAA and associated intracardisc defects were surgically repaired in single-stage through median stermotomy,inchud-ing 9 coanctation of aorta,12 coarctation with aortic arch hypoplasia,and 3 interrupted aorlic arch,.The associated intracardiac de-fects were Taussing-Bing anomaly 4,non-restricted VSD 22,subaortic stenosis 1 and pulmonary vein stenosis 1.The age ranged form 1 to 99 months (average 16 months) and the body weight ranged from 4 to 19 kg(average 9.3 kg).Aortic arch reconstruction was performed by hypothermic continuous low flow bypass using regional perfusion for all patients.Three patients with LAA and 9 patients with CoA underwent end-to-end ansetomosis.Of the 12 patients with coarctation and aortic arch hyipoplasia,8 patiellts underwent ex-tended end-to-end anastomosis,2 patients underwent end-to-side anastomosis and 2 patients underwent aortoplasfy.Results 2 cases were dead. One infant with Taussig-Bing type heart was dead of severe infection after 47 days postoperative,the other one who associ-ated with LAA and VSD dead of pulmonary hypertension crisis due to pneumonia after 15 days postoperative.No patient presented neu-rdogieal complication and renal insufficiency during the perioperation.2 cases presented recurrent respiratory problem.During the 18months follow-up,no patient presented with recoarctation except one with pressure gradient more than 20 mm Hg.Conclusion Pa-tients with coarctation of aorta or interrupted aortic arch and associsted intracardisc defects should be surgically treated as early as pos-sible when diagnosis was mode.Single-stage sortic arch reconstruction through median stemotomy using continuous regional perfusion is an effective and safe procedurd.Sufficient resection of ductus,extensive dissection of thoracic vessels and optimal tissus-tissue anas-tomosis techmique are very important for successful repair and avoiding recoarctation.

OBJECTIVETo investigate the clinical effect and safety of chiropractic in treating cervicogenic sudden hearing loss.

METHODSFrom January 2011 to October 2013, 90 patients with cervicogenic sudden hearing loss were randomly divided into treatment group and control group according to the random number table produced by SPSS 19.0 software. In the treatment group, there were 17 males and 28 females, aged from 31 to 62 years old with an average of (47.57±9.43) years; course of disease was from 1 to 3 days with an average of (1.43±0.68) days; pure-tone audiometry score was from 46.5 to 77.8 dB with the mean of (61.20±9.83) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 17 to 31 scores with an average of (23.46±7.18) scores. In the control group, there were 15 males and 30 females, aged from 28 to 64 years old with an average of (45.77±6.99) years; course of disease was from 1 to 3 days with an average of (1.50±0.73) days; pure-tone audiometry score was from 48.1 to 75.0 dB with the mean of (63.91±8.05) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 20 to 29 scores with an average of (25.61±10.43) scores. The patients of control group were treated with dexamethasone intravenous drip of 10 mg, 3 days later, decreased to 5 mg, 3 days again. And with the methycobal intravenous drip of 500 μg, treatment continued for 10 days. The patients of treatment group were treated with chiropractic additionally except for the therapeutic methods of control group. Chiropractic included local muscle loosening, attacking point, bilateral pulling atlanto-axial joint, and continuous treatment for 10 days. The pure-tone audiometry score and NPQ score were compared between two groups after treatment.

RESULTSAfter the treatment, pure-tone audiometry score and NPQ score in treatment group improved to (40.23± 8.14) dB and (12.70±8.29) scores respectively, which were obviously better than that of control group's (37.70±10.61) dB and (21.24±11.13) scores (P<0.05).

CONCLUSIONCompared with routine method for cervicogenic sudden hearing loss, additional chiropractic can improve hearing and relieve neck pain effectively.

Objective To investigate the mechanism of acute inflammatory response and tissue repair when rats accepted transplanted bone marrow mesenchymal stem cells (MSC) in severe acute pancreatitis (SAP).Methods A total of 40 rats were randomly divided into 4 groups which included the normal group (n=10),the model severe acute pancreatitis group (n=10),the transplanted bone marrow mesenchymal stem cells group (n =10),and the combination of bone marrow mesenchymal stem cells and granulocyte colony-stimulating factor (G-CSF) group (n=10).To cure the acute severe pancreatic injury caused by SAP,rats were injected with EDU-labeled MSCs and granulocyte colonystimulating factor (Gr-CSF).The conversion rate of MSCs to pancreatic cells or MSCs to endothelial cells was detected to assess the role of MSCs in tissue regeneration and repair.The expression of amylase,interleukin-6 (IL-6),and interleukin-10 (IL-10) in serum was detected to assess the role of MSCs in an acute inflammatory response.Results The concentrations of amylase and IL-6 were reduced and the concentration of IL-10 was increased in MSC and MSC+G-CSF groups after the onset of SAP.Flow cytometry showed a small amount of MSCs converting to endothelial or pancreatic cells,but the conversion rate was relatively low.Conclusions MSCs can play an important role in the antipre-release of inflammatory mediators,reducing acute immune response to control the acute inflammatory response in SAP.Moreover,MSCs can repair a damaged pancreas by converting into both pancreatic and endothelial cells.
