Objective To study the analgesic effect of Eupatorium odoratum L and its mechanism .Methods Mice were random‐ly divided into 6 groups .Swinging tail method in spinal cord destroyed mouse ,hot‐plate and twisted body method in naloxone blocked mouse ,and formalin‐induce inflammatory pain method were done to investigate the analgesic effect of Eupatorium odoratum L .Each pain index under each experiment condition was determined after intra gastric administration of each group of mice .The concentration of NO and PGE2 in serum and brain were measured to study its mechanisms .Results High‐dose of Eupatorium odor‐atum L significantly enhanced pain threshold in either spinal cord destroyed or naloxone blocked mouse with pain induced by hot and acetic acid(P<0 .05) .High and middle dosage groups of Eupatorium odoratum L markedly reduced the first‐and second‐phase re‐sponses of formalin‐induced inflammatory pain mouse(P< 0 .05) ,and decreased the writhing times and licking rear feet times caused by twisted body method(P<0 .05) .The level of NO and PGE2 in serum and brain of mouse induced by formalin were both decreased(P<0 .05) .Conclusion Eupatorium odoratum L has notable analgesic effect ,which may be related to reduce the level of NO and PGE2 in central and peripheral site .

Objective To investigate the effect of humidified high flow nasal cannula (HHFNC) on severe apnea in preterm infants.Methods Eighty-two preterm infants who developed apnea more than twice in short time,recurred within 6 hours or needed mask respirator were divided into HHFNC group(n =40) and nasal continuous positive airway pressure(NCPAP) group (n =42).Both groups were given aminophylline intravenously.The total therapeutic effect rate,the number of cases who needed mechanical ventilation during the observation period,the duration of non-invasive ventilation,the duration of oxygen therapy,the oxygen exchange indexes and the complications of two groups were observed.Results There were no significant differences between two groups in the therapeutic effect rate,the number of cases who need invasive ventilation,the duration of non-invasive ventilation time,oxygen exchange indexes and the duration of oxygen usage (P ＞ 0.05).The numbers of nose injury of HHFNC group were less than those of the NCPAP group [10.0％ (4/40) vs.30.9％ (13/42)] (P ＜0.05).No significant differences were found between two groups in the complication of necrotizing enterocolitis or feeding intolerance,respiratory infection,retinopathy of prematurity,bronchopulmonary dysplasia (P ＜ 0.05).Conclusion HHFNC has the same effect as NCPAP in the treatment of severe apnea in preterm infants except for lower prevalence of nose injury.

ObjectiveTo explore the pathogenesis, clinical manifestations, diagnosis, and treatment of autoanti-body-associated congenital heart block.MethodsThe clinical data of one child with autoantibody-associated congenital heart block was retrospectively analyzed.ResultsIn 24 week gestation, fetal bradycardia had been found by routine fetal echocar-diography. After birth, the anti-SSA/Ro antibodies and anti-SSB/La antibodies were positive in both infant and her mother. The diagnosis of autoantibody-associated congenital heart block was conifrmed. Intravenous immunoglobulin at 1 g/kg was adminis-trated. At 6 months follow-up, the electrocardiogram suggested type I second degree atrioventricular block.ConclusionIn the fetus or neonates found to have bradycardia and excluded the cardiac structural abnormalities, the autoimmune antibody should been tested and early intervention should been promoted.

In order to explore the significance of enterovirus environmental surveillance of sewage,two sewage treatment plants in Fuzhou City were selected as sentinel surveillance sites.One sewage sample was collected from entrance of each plant every month,and total 48 samples were studied from 2013 to 2014 in Fuzhou City.Using the RD,L20B and Hep-2 cell lines to isolate the viruses,44 of the 48 sewage samples (91.67％) were positive,268 strains were isolated which covered at least 22 enterovirus serotypes.The peak season of virus isolation from sewage was in February and July which was two months earlier than patient surveillance.Eehovirus type 7 (Echo 7) was the predominant serotype in 2013 with 58 isolations (43.61％),and in 2014 echovirus type 6 (ECHO 6) became the predominant serotype with 85 isolates (62.96％),among the strains isolated from sewage sample.Phylogenetic analysis found that the predominant serotype Echo 6 and Echo 7 isolated from sewage were more diversified than that from clinical cases during the same period,and were high homology with isolates form patients which belong to same branch in phylogenetic tree.In conclusion,enterovirus environmental sewage surveillance is an effective approach,and could be more sensitive than patient surveillance.

[Objective] To investigate the occurrence rate, manifestations and influencing factors of emotional disorder in patients after acute stroke. [Methods] Emotional disorder in 107 cases of acute stroke was assessed by 17-item Hamilton Depression Scales (HAMD), 14-item Hamilton Anxiety Scales (KAMA), Mini-Mental State Examination (MMSE) and Barthel index (BI), and the relationship between emotional disorder and influencing factors were also analyzed. [Results] The occurrence rate of emotional disorder after acute stroke was 41.12% , in which depression was 18.69% , anxiety 9.35% and concurrence of depression and anxiety 13.08% . Emotional disorder usually occurred in the dominant hemisphere of young patients with lower BI after repeated attacks of stroke; its manifestations relieved with the cure of primary diseases. Its dominant syndrome pattern was classified as stagnation of liver-Qi. [ Conclusion ] Emotional disorder, possibly being a stress reaction, is the common complications of acute stroke and usually classified as stagnation of liver-Qi; early effective rehabilitation is the best preventive method for emotional disorder acute stroke.

The morbidity of diabetes has been increasing rapidly in recent years. Delayed wound healing has become a common complication in diabetes, which seriously affects the orthobiosis of patients. Exploring and finding the molecular mechanisms of diabetic wound healing and the effective therapies to promote wound healing have important clinical significances. Stem cells transplant has become a research hotspot in accelerating diabetic wound healing. This article reviewed the present approaches concerning stem cells transplant in diabetic wound healing both at domestic and abroad, and looked forward the clinical therapy of stem cells on diabetic wound healing.

Objective To investigate the anti-inflammatory mechanism by which curcumin affects TNF-αand IL-8 production in Propionibactierium acnes-induced THP-1 cells. Methods THP-1 cell viability was determined by CCK8 assay. The productions of TNF-α and IL-8 were detected by ELISA assay. Total RNA and proteins were collected for real-time PCR and Western blot analysis, respectively. Results Curcumin didn′t significantly affect the cell viability at 12 h. It decreased Propionibactierium acnes-induced productions of TNF-αand IL-8 in THP-1 cells. Moreover, it decreased TLR2, NF-κB p65, and P-NF-κB p65 expressions in THP-1 cells. Conclusions Curcumin may reduce TNF-α and IL-8 expressions in Propionibactierium acnes-induced THP-1 cells by inhibiting TLR2/NF-κB signaling pathway.
