Aim To observe the effect of epidurally application of osthole on the model of nucleus pulposusinduced inflammatory radicular pain and the expression of p38 MAPK signaling related pathway in the spinal dorsal horn of rats.Methods The model of radicular pain was generated by putting nucleus pulposus to the L5 dorsal root ganglion (DRG).50％ MWT was measured using Von Frey filaments to calculate mechanical pain threshold before and after operation.50 μL of 20 g · L-1 osthole was administered epidurally in group Ost and 50 μL of 100 mL · L-1 DMSO in group DMSO at postoperative day (POD).The expression of phosphorylated p38 (p-p38),IL-18 and IL-18R in the lumbar spinal dorsal horn was detected by Western blot.IL-18 mRNA was assessed by real-time PCR.Results The mechanical pain threshold significantly decreased after operation (P ＜ 0.05),while the expression of protein p-p38 MAPK,IL-18,IL-18R and IL-18 mRNA was significantly different.Compared with DMSO group,50％ MWT was significantly increased and accompanied with the decrease of protein p-p38,IL-18,IL-lgR and IL-18 mRNA in Ost group after drug administration (P ＜ 0.05).The correlation analysis between protein concentration of p38 MAPK and IL-18 mRNA showed that the Spearman correlation coefficient was 0.9 (P ＜ 0.05).Conclusion p-p38 and IL-18 of spinal dorsal horn participate in the rat model with inflammatory radicular pain induced by nucleus pulposus,and IL-18R plays a role in maintenance of the pain.Osthole administered epidurally in the early stage of pain could alleviate the pain for a long time,which may be related with inhibiting p38 MAPK signaling related pathways.

OBJECTIVETo understand the risk factors of schistosomiasis transmission in the Three Gorges Reservoir Area (TGRA) and to provide evidence for the development of control strategy.

METHODSApproaches including epidemiology, immunology and field survey were applied to investigate the potential risk factors which would involve the importation of infectious resources live mobile and migrant population, and livestock in the reservoir area. Meanwhile, observation on survival and reproductive status of snail under simulation habitats was also carried out, using ecological methods on snails. Strategy in preventing the spread of snail as infectious resources was also provided.

RESULTS175 mobile people from schistosomaisis endemic area of were tested and one person showed immunology tests positive with indirect hemagglutination test (IHA) and circumoral precipitin test (COPT), with a positive rate of 0.57%. Through the two-year period under observation, data showed that the snails with ribbon/smooth shells could survive and reproduce under habitats of simulation.

CONCLUSIONSOnce the infectious resource of schistosomiasis was introduced into the TGRA, the area became a new schistosomiasis epidemic area in TGRA which called for countermeasures to be taken.

OBJECTIVETo verify the anti-depression effect of acupuncture and moxibustion based on the medication with selective serotonin reuptake inhibitors (SSRIs).

METHODSEighty cases of depression were randomly divided into an acupuncture-moxibustion-medication group (25 cases), an acupuncture-medication group (25 cases) and a medication group (30 cases). SSRIs medication was administered in all of the three groups. Complementarily, in acupuncture-moxibustion-medication group, the needling technique of qi conduction in the Governor Vessel was applied to Baihui (GV 20), Fengfu (GV 16), Dazhui (GV 14), etc. Additionally, mild moxibustion was added at Dazhui (GV 14) and Baihui (GV 20). In acupuncture-medication group, acupuncture for qi conduction in the Governor Vessel was only adopted. Hamilton Depression Scale (HAMD) was used for the evaluation of the total score, the score of each factor before and after treatment separately, and the therapeutic effects were observed among 3 groups.

RESULTSCompared with medication group, the scores of the factors as retardation, sleep, and anxiety/somatization, as well as the total score were all apparently improved in the other two groups (P < 0.05, P < 0.01). Compared with acupuncture-medication group, the scores of sleep and cognition factors as well as the total score in HAMD were much improved in acupuncture-moxibustion-medication group (P < 0.05, P < 0.01). The remarkable effective rates were 100.0% (25/25), 84.0% (21/25) and 56.7% (17/30) in the three groups separately, in which, the result in acupuncture-moxibustion-medication group was superior to acupuncture-medication group (P < 0.05), and the results of these two groups were superior to medication group (both P < 0.01).

CONCLUSIONEither acupunctrure or moxibustion has a definite anti-depression effect based on SSRIs medication, but the coordination of acupuncture and moxibustion achieves a superior efficacy as compared with simple acupuncture therapy.

OBJECTIVETo examine the long-term outcomes of total colonic aganglionosis (TCA) and to evaluate their nutritional status.

METHODSEleven pediatric patients treated for TCA between January 1999 and December 2010 were included in the study and followed up. Physical measurements including height, weight and laboratory tests were assessed. Anorectal functions were evaluated with Kelly score and quality of life(QOL) using questionnaire.

RESULTSThe length of follow-up ranged from 8 to 147 months. The children had satisfactory anorectal function (Kelly score, 5-6). One child had a Kelly score of 3. The children who were followed up less than 48 months had significant higher Kelly scores compared with those with more than 48 months follow-up(P<0.05). QOL was good in nine patients (QOL score, 9-10) and moderate (score, 7-8) in 2 patients. Weight-for-age was normal in 2 patients, mild malnutrition in 6 patients, and moderate malnutrition in 3 patients. Height-for-age was normal in 6 patients, mild malnutrition in 3 patients, and moderate malnutrition in 2 patients. The serum albumin was(49.0±2.7) g/L in children with well-educated parents, significantly higher than those with poorly-educated parents(44.3±1.9) g/L(P<0.05).

CONCLUSIONSLong-term outcomes of children with TCA are satisfactory with good anorectal function and quality of life. Low body weight is more common than low height. Children with well-educated parents have better nutrition status.

OBJECTIVETo compare the efficacy and safety of domestic levosimendan versus dobutamine for patients with acute decompensated heart failure (ADHF).

METHODSADHF patients from 8 medical centers were recruited in this multicenter, blind, positive-controlled, randomized study and received 24 h intravenous levosimendan (n = 114) or dobutamine (n = 114) therapy. SWAN-GANZ catheter was performed in patients with pulmonary capillary wedge pressure (PCWP) ≥ 15 mm Hg (1 mm Hg = 0.133 kPa) and cardiac index (CI) ≤ 2.5 L·min(-1)×m(-2) (n = 39 each).

RESULTSCompared with baseline level, LVEF increased [(31.56 ± 9.69)% vs. (28.44 ± 7.08)%, P < 0.01] at 24 h in both groups. LVEF increase at 24 h was similar between two groups [(3.11 ± 6.90)% vs. (3.00 ± 6.63)%, P > 0.05]. The PCWP decrease at 24 h was significantly greater in levosimendan group than in dobutamine group [(-8.90 ± 7.14) mm Hg vs. (-5.64 ± 6.83) mm Hg, P = 0.04]. Decrease in NT-proBNP at 3 days was also more significant in levosimendan group than in dobutamine group [the percentage change compared to baseline: (-22.36 ± 38.98)% vs. (-8.56 ± 42.42)%, P < 0.01]. Dyspnea improvement at 24 h was more significant in levosimendan group than in dobutamine group. The incidences of adverse reactions and events were similar between two groups.

CONCLUSIONLVEF improvement is similar between dobutamine and domestic levosimendan while greater decreases in PCWP and NT-proBNP are achieved with domestic levosimendan in patients with ADHF.

Hypoxemia is a common complication of pneumonia, asthma, and bronchopulmonary dysplasia in children.Rapid identification of hypoxemia is of great significance for the disposal and management of critical children.Pulse oximetry is recognized by the World Health Organization as the best way to monitor hypoxemia in children, and it can monitor pulse oxygen saturation noninvasively and continuously.Based on the related literature at home and abroad, combined with the clinical needs of pediatrics, the " Expert consensus on clinical application of pulse oximetry in children" is formulated to improve the understanding of pediatricians and nurses on the application in pediatric clinical practice, principle, operation techniques, and limitations of pulse oximetry.
