OBJECTIVETo evaluate the effect of electro-acupuncture (EA) on gastric mucosal oxygenation and systemic inflammatory response in patients undergoing endoscopic sinus surgery with controlled hypotension (CH), and to explore its protective effect on gastric mucosa.

METHODSFifty-four patients, 18-65 years old, grade I-II of American Society of Anesthesiology (ASA), who were scheduled for endoscopic sinus surgery were randomly assigned to two groups, group A (general anesthesia group) and group B (general anesthesia combined EA anesthesia group), 27 in each group. Conrolled hypotension was executed during operation, and mean arterial pressure (MAP) was maintained at 55-65 mmHg. After tracheal intubation gastric tesiometer catheter was indwelled through nasal cavity or oral cavity. After successful indwelling, it was connected with gastric mucosa monitoring mode of multifunctional parameters monitor. Patients' MAP and heart rate (HR), pHi, partial pressure of carbon dioxide (PgCO2), arterial partial pressure of carbon dioxide (Pg-aCO2) and endtidal pressure of carbon dioxide (Pg-etCO2) were measured and recorded at T, (immediately before induced hypotension), T, (20 min following induced hypotension to target MAP), T2 (40 min following induced hypotension to target MAP), T3 (20 min after ending induced hypotension), and T4(40 min after ending induced hypotension). Blood samples were intravenously collected, TNF-alpha, IL-1, and IL-6 were detected by ELISA 24 h before operation, during operation (T3), and 24 h after operation.

RESULTSAfter hypotension was induced, Pg-CO2, Pg-aCO2 and Pg-etCO2 increased significantly (P < 0.01, P < 0.05), while pHi decreased significantly (P < 0.01) in both groups at T1-T4 than those at T0. During T1-T4, PgCO2, Pg-aCO2, and Pg-etCO2 were higher (P < 0.01, P < 0.05), while pHi was lower in group A than in group B (P < 0.01). Furthermore, TNF-alpha, IL-1, and IL-6 increased significantly in both groups during operation and 24 h after operation, when compared with those 24 h before operation (P < 0.01, P < 0.05). TNF-alpha and IL-1 in group A were higher than those in group B (P < 0.05) during operation and 24 h after operation, but with no significant difference in the plasma concentration of IL-6 (P > 0.05).

CONCLUSIONEA exerted obvious protective effect of gastric mucosal injury in endoscopic sinus surgery with controlled hypotension, which might be achieved by increasing gastric mucosal blood flow, maintaining oxygen supply and demand, inhibiting inflammatory response, and alleviating injury of gastric mucosal barrier.

Objective To study the clinical significance of pulmonary membrane diffusing capacity(Dm) and pulmonary capillary blood volume(Vc) in patients with stable chronic obstructive pulmonary disease(COPD). Methods Spirometry was performed in 38 patients with stable COPD and 35 healthy individuals in resting condition.The changes of pulmonary parameters were obtained and compared between groups. Results Spirometry test revealed that the percent predicted forced expired volume in one second(FEV1),FEV1/forced volume capacity(FVC)and the percent predicted maximal ventilatory volume(MVV) were declined from stage Ⅰin patients with COPD in comparison with healthy individuals,while diffusing capacity for carbon monoxide of lung(DLCO),carbon monoxide diffusing capacity per liter of alveolar(DLCO/VA),Dm and Vc were declined from stage Ⅱ.Dm in patients with COPD of stageⅠwas sig-nificantly decreased compared with the controls,while Vc was increased compared with the controls(both P

Objective To investigate the clinical effect of mild hypothermia on neonatal bilirubin encephalopathy, and the value of 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT and amplitude integrated electroencephalogram (aEEG) for diagnosis and evaluation of curative effect. Methods From May, 2013 to December, 2014, 29 newborns with bilirubin encephalopathy were divided into conventional group (n=15) and mild hypothermia group (n=14). The conventional group received conventional therapy, and the other group received mild hypothermia in addition. The aEEG and neuron-specific enolase (NSE) were measured before and after treatment, as well as the glucose metabolism rate with 18F-FDG PET/CT after treatment. Results The NSE was lower after treatment in both groups (t>9.670, P<0.001), and was lower in the mild hypothermia group than in the conventional group (F=46.146, P<0.001). After treatment, sleep-wake cycle (SWC), epileptiform activity and the degree of abnormality were obviously improved (P<0.05), and were better in the mild hypothermia group than in the conventional group (P<0.05). The cerebral glucose metabolism rate was significantly better in the mild hypo-thermia group than in the conventional group (t>2.943, P<0.01). The cerebral glucose metabolism rate was negatively correlated with aEEG and NSE (r>0.640, P<0.05). Conclusion Mild hypothermia therapy could further promote the energy metabolism of brain cells in neonatal bilirubin encephalopathy. 18F-FDG PET/CT and aEEG can be used for early diagnosis and therapeutic evaluation.

OBJECTIVETo compare the differences in the clinical function and lumbar and abdominal myodynamia in patiants of lumbar disc herniation treated with moxibustion at Dazhui (GV 14) and Guanyuan (CV 4) and acupuncture.

METHODSForty cases were randomized into a moxibustion group and an acupuncture group, 20 cases in each group. In the moxibustion group, the warm moxibustion was applied alternatively at Dazhui (GV 14) and Guanyuan (CV 4) once every other day, 1 h each time, once every day. In the acupuncture group, acupuncture was applied to the corresponding acupoints based on the affected lumbar vertebras, such as Jiaji (EX-B 2), Shens-hu (BL 23), Dachangshu (BL 25) and Huantiao (GB 30), etc. , once evey day 30 min each time. The treatment for 3 weeks was taken as one session in each group. Totally, one session treatment was required. Surface electromyography (SEMG) of bilateral paraspinal muscle and rectus muscle, and JOA score of low back pain were observed in the two groups.

RESULTS(1) JOA score: the score of subjective symptoms, score of activity of daily living (ADL) and total score were improved obviously as compared with those before treatment in the two groups (P<0.01, P<0.05). The results of subjective symptoms score, score of ADL and total score in the acupuncture group were superior to those in the moxibustion group after treatment (6.95+/-0.94 vs 5.50 +/-0.89,10. 90+/-1.86 vs 8.90+/- 1. 92,22.50 +/- 2.82 vs 19.35 +/- 2. 70, all P<0. 05). (2) SEMG comparison: root-mean-square value (RMS) was all reduced in SEMG of the anteflexion, rear protraction, orthostatism, bilateral bending and neck and leg rear flexion for strengthening lumbar muscle as compared with those before treatment in the two groups (P< 0.05, P<0. 01). RMS of the anteflexion and bilateral bending in the acupunture group were reduced much obviously as compared with the moxibustion group. In terms of sitting position anteflexion, rear protraction, orthostatism, bilateral bending and neck and leg rear flexion for strengthening lumbar muscle, median frequency (MF) after treatment was all improved as compared with that before treatment in the two groups (P<0. 05, P<0. 01). In terms of anteflexion, the electrode MF after treatment was improved much obviously in the acupuncture group(P<0. 05).

CONCLUSIONMoxibustion at Dazhui (GV 14) and Guanyuan (CV 4) and conventional acupuncture all improve muscle function, relieve muscle fatigue, increase the ability of anti-muscle fatigue, strengthen lumbar vertebral stability, release subjective symptoms and improve ADL. But, the effects of moxibustion are slightly lower than those of acupuncture.

This study was aimed to establish a stable animal model of left ventricular hypertrophy (LVH) to provide theoretical and experimental basis for understanding the development of LVH. The abdominal aorta of male Wistar rats (80-100 g) was constricted to a diameter of 0.55 mm between the branches of the celiac and anterior mesenteric arteries. Echocardiography using a linear phased array probe was performed as well as pathological examination and plasma B-type natriuretic peptide (BNP) measurement at 3, 4 and 6 weeks after abdominal aortic constriction (AAC). The results showed that the acute mortality rate (within 24 h) of this modified rat model was 8%. Animals who underwent AAC demonstrated significantly increased interventricular septal (IVS), LV posterior wall (LVPWd), LV mass index (LVMI), cross-sectional area (CSA) of myocytes, and perivascular fibrosis; the ejection fraction (EF), fractional shortening (FS), and cardiac output (CO) were consistently lower at each time point after AAC. Notably, differences in these parameters between AAC group and sham group were significant by 3 weeks and reached peaks at 4th week. Following AAC, the plasma BNP was gradually elevated compared with the sham group at 3rd and 6th week. It was concluded that this modified AAC model can develop LVH, both stably and safely, by week four post-surgery; echocardiography is able to assess changes in chamber dimensions and systolic properties accurately in rats with LVH.
