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.

OBJECTIVETo investigate the potential effects on cognitive function, prognosis, and neuropeptide levels of patients in response to combination therapy with ornithine aspartate plus naloxone for hepatic encephalopathy.

METHODSEighty-four consecutive patients diagnosed with hepatic encephalopathy were randomly divided into two equal groups. The control group (n = 42) received traditional medical treatment, and the research group (n = 42) received the traditional medical treatment as well as the combination therapy with ornithine aspartate plus naloxone. The supplemental treatment was comprised of daily intravenous injection of 10-15 g ornithine aspartate in 250 ml of 5% glucose plus intravenous drip of 3 mg naloxone in 100 ml of 5% glucose, and was given in 7-day cycles for one or two cycles. The cognitive function of patients was assessed by Hasegawa Intelligence Scale (HDS) and Mini-Mental State Examination (MMSE) questionnaires. The effective rate and time duration from coma to consciousness were recorded. Changes in blood ammonia level, markers of liver function, and neuropeptide levels were measured by standard biochemical assays. Intergroup differences were assessed by the Chi-squared test.

RESULTSThe HDS and MMSE scores of the research group were significantly higher than those of the control group after therapy. The effective rate, time duration from coma to consciousness, blood ammonia, the liver function markers alanine aminotransferase, gamma-glutamyl-transpeptidase and total bilirubin, and the neuropeptides arginine vasopressin and beta-endorphin were remarkably improved after treatment in the research group, as compared with that in the control group.

CONCLUSIONSupplementing the traditional treatment for hepatic encephalopathy with ornithine aspartate plus naloxone combination therapy provides better therapeutic outcome than traditional treatment alone.

OBJECTIVETo study the effect of selective moderate head cooling therapy on maximum length sequences brainstem auditory evoked potential (MLS-BAEP) in newborn piglets with hypoxic-ischemic brain damage.

METHODSSixteen newborn piglets aged 5-7 day old were randomly divided into three groups: normothermic control (n=4), HI (n=6) and mild hypothermia-treated (n=6). HI was induced through temporary occlusion of both carotid arteries, followed by mechanical ventilation with low concentration of oxygen (FiO2=0.06) for 30 minutes. Mild hypothermia was induced by equipment via circulating water. MLS-BAER was recorded before HI and at 12 hours, 24 hours, 36 hours, 48 hours, 60 hours, 72 hours, 4 days, 7 days, 10 days, 13 days and 15 days after HI.

RESULTSCompared with the normothermic control group, all latencies and intervals tended to increase significantly at 72 hours in the HI group and reached peak values on day 7. From day 10, all latencies and intervals tended to decrease, but apart from wave I latency, still differed significantly from those of the normothermic control group. MLS-BAER variables did not reach normal values until day 15. Ⅲ latency, Ⅰ-Ⅲ interval and Ⅰ-Ⅴ interval were significantly reduced in the hypothermia-treated group between 60 and 7 days after HI compared with the HI group (P<0.05). V latency and Ⅲ-Ⅴ interval in the hypothermia-treated group were also reduced compared with the HI group between 72 hours and 7 days after HI (P<0.05).

CONCLUSIONSBoth peripheral and central auditory systems are disturbed by HI, which shows as a significant increase in MLS-BAER variables (all latencies and intervals) in newborn piglets. Involvement in central brainstem auditory system reaches a peak on day 7 after injury. MLS-BAER variables still cannot reach to normal values until day 15. Selective moderate head cooling therapy can significantly reduce brainstem damage induced by HI.

BACKGROUNDThe second mitochondria-derived activator of caspases (Smac) is a novel proapoptotic gene, which plays an important role in the apoptosis-inducing effects of irradiation on tumor cells. The purpose of this study was to investigate the effects of extrinsic Smac gene transfer and its over-expression in radiotherapeutic sensitivities of cervical cancer cells.

METHODSAfter the Smac gene was transferred into the cervical cancer cell line HeLa, subcloned cells were obtained by persistent G418 selection. Cellular Smac gene expression was detected by RT-PCR and Western blot, while in vitro cell viabilities were detected by trypan blue staining assay. After treatment with X-ray irradiation, cellular radiotherapeutic sensitivities were investigated by tetrazolium bromide colorimetry. Cellular apoptosis and its rate were determined by electronic microscopy, annexin V-FITC and propidium iodide staining flow cytometry. The expression and activities of cellular caspase-3 were assayed by Western blot and colorimetry.

RESULTSSmac mRNA and protein levels in HeLa/Smac cells and the selected subclone cell line of cervical cancer were significantly higher than those of HeLa (P < 0.01). There was no significant difference in cellular viabilities between them (P > 0.05). However, after irradiation with 8 Gy X-ray, growth activities of HeLa/Smac were reduced by 22.42% (P < 0.01). When compared with those of HeLa, partial HeLa/Smac cells presented characteristic morphological changes of apoptosis under electronic microscope, with higher apoptosis rates (16.4% vs. 6.2%, P < 0.01); the caspase-3 expression levels in HeLa/Smac cells were improved significantly (P < 0.01), while its activities were increased by 3.42 times (P < 0.01).

CONCLUSIONSStable transfer of the extrinsic Smac gene and its over-expression in cervical cancer cell line could significantly enhance the expression and activities of cellular caspase-3 and ameliorate apoptosis-inducing effects of irradiation on cancer cells, which was a novel strategy to improve radiotherapeutic effects on cervical cancer.

Objective To investigate the predictive value of neutrophil to lymphocyte ratio (NLR) at admission for large vessel occlusion (LVO) in patients with acute ischemic stroke. Methods The clinical data of patients with acute ischemic stroke admitted to Guangzhou First People's Hospital from January 2016 to November 2017 were enrolled retrospectively. NLR was calculated according to results of blood routine examination within 6 h after admission. Multivariate logistic regression analysis was used to determine the independent correlation between NLR and LVO. The receiver operating characteristic (ROC) curve was used to analyze the predictive value of NLR for LVO. Results A total of 109 patients with acute ischemic stroke were enrolled, including 42 females (38. 5％) and 67 males (61. 5％). Their mean age was 63. 6 years. Forty-six patients (42. 2％) had LVO. The proportions of patients with atrial fibrillation, previous stroke or transient ischemic attack, and the National Institutes of Health Stroke Scale score, white cell count, NLR, neutrophil count, and fasting blood glucose in the LVO group were significantly higher than those in the non- LVO group, while lymphocyte count was significantly lower than that in the non-LVO group (all P < 0. 05). Multivariate logistic regression analysis showed that NLR was an independent risk factor for LVO after adjusting for the confounding factors (odds ratio 2. 768, 95％ confidence interval, 2. 272-4. 984; P = 0. 001). The ROC curve analysis of NLR predicting LVO showed that the area under the curve was 0. 712 (95％ confidence interval 0. 638-0. 793), and the sensitivity and specificity were 79. 3％ and 73. 6％ respectively as the optimal cut-off value was 4. 18. Conclusions Increased NLR in early peripheral blood may effectively predict LVO in acute ischemic stroke.
