Objective To study the efficiency of large dose intravenous immunoglobulin(IVIG) in decreasing incidence of asthma following bronchiolitis.Methods One hundred and sixty-eight children with bronchiolitis were chosen to use different treatment plans,81 children receiving large dose of IVIG[ 0.4 g/(kg?d)] daily,on the basis of routine treatment for 5 days,while other 87 children were reserved as control group receiving routine treatment only,which were followed up 5 to 10 years.Results After following up 5 to 10 years,only 17 cases in 81 patients with bronchiolitis receiving large dose IVIG developed into asthma.However,46 cases in control group developed into asthma.The incidence of asthma was 20.99% and(52.87%) in two groups,respectively,showing significant(differe-)nce between them(P

Objective To observe the incidence of bronchial asthma thereafter by 3 to 10 years′ follow-up of 280 children with bronchio-litis and analyze the correlation factors affecting the development of asthma.Methods Two hundred and eighty children with bronchitis were chosen and treated from Jan.1995 to Dec.2002,220 males,and 60 females.The review research and clinical revisits were carried out to investigate and analyze the subjects in terms of whether receiving large dose of intravenous injection immunoglobulin(IVIG) treatment or not,whether getting vaccinated with bacille calmette guerin(BCG)as planed or not,whether having asthma family history and the allergic physique or not,the way of feeding,and so on.Results The rate of asthma was 29.29%(82/280),and the incidence of asthma was significantly lower in children with administering the large dose of IVIG,vaccinating BCG vaccine as planed,having no allergic physique,having no asthma family history or breast feeding than those without administering the large dose of IVIG,vaccinating BCG vaccine as planed,brest feeding,with allergic physique,asthma family history(Pa

27-O-(E)-p-coumaric acyl ursolic acid( DY-17) from Ilex latifolia is a compound of the monomer. To investigate the DY-17 inducing apoptosis in the human breast cancer cell line, the MDA-MB-231 cells were used as research object in this experiment. The proliferation activity of the MDA-MB-231 cells stimulated with the different concentrations of DY-17 (20, 40 µmol · L(-1)) was detected at different time( 12, 24, 36, 48, 60,72 h) . We surveyed the DY-17 inducing apoptosis of the MDA-MB-231 cells with the fluorescent staining technology. The rate of MDA-MB-231 cells apoptosis and necrosis was determined by flow cell cytometry (FCC). Moreover, expression of JNK, phosphorylated JNK, Bax, PARP shear and caspase-3 shear related to JNK/SAPK pathways were investigated in every group ( control group, EGF group, EGF + DY-17 40 µmol · L(1) group and EGF + SP600125 group) with Western blot. The MTT results showed that, in the presence of DY-17, the proliferation activity of MDA-MB-231 cells decreased in a dose-dependent and time-dependent manner. The apoptosis and necrosis rates of MDA-MB-231 cells with DY-17(20, 40 µmol · L(-1)) groups was respectively 31.86%, 49.91% by flow cytometry and significantly increased compared with control group under Fluores- cence microscopy. Up-regulation of the JNK phosphorylation protein expression was observed in EGF group compared with control group. In addition, markedly decreased the expression of JNK phosphorylation protein were also surveyed in EGF + DY-17 40 µmol · L(-1) group compared with EGF group. The expression of Bax, shear PARP and shear caspase-3 protein in EGF + DY-17 40 µmol · L(-1) group were significantly increased in comparison with EGF group. The results showed DY-17 induced apoptosis of human breast cancer MDA-MB-231 cell line related to down-regulating JNK/SAPK signal pathways.

Abstract: Objective　This study aims to explore the prevalence and risk factors of metabolic syndrome (MS) among the adults in Hainan Province, and to provide scientific basis for MS prevention and control. Methods　A multi-stage cluster random sampling method was applied to select 3 690 permanent residents aged 18 years and above in Hainan Province. The survey was conducted by trained investigators using household appointments and centralized surveys. A questionnaire survey, physical measurement, and laboratory examination were conducted after the collection of blood samples. The processed samples were then tested by a quality-controlled laboratory. Finally, we analysed the prevalence of metabolic syndrome (MS) and its relationship with population characteristics and health-related behaviors. Results　The crude prevalence of MS in the population aged 18 and above in Hainan province was 19.46% and the standardized prevalence was 13.21%, with a higher rate in urban areas (22.21%) than in rural areas (18.13%). The prevalence of MS increased with age (P<0.001), and there were significant differences in MS prevalence among different marital and occupational statuses (P<0.01). Logistic regression results indicated that the age groups of 40-<50 years (OR=2.986, 95%CI:1.355-6.580), 50-<60 years (OR=3.739, 95%CI: 1.715-8.151), 60-<70 years (OR=3.890, 95%CI: 1.769-8.556), 70 years and above (OR=3.927, 95%CI: 1.758-8.771), technical, transportation and production personnel (OR=1.579, 95%CI: 1.033-2.412), retired (OR=1.788, 95%CI: 1.415-2.259), unemployed (OR=1.503, 95%CI: 1.044-2.165), smoking cessation (OR=1.582, 95%CI: 1.162-2.154), insufficient intake of fruits and vegetables (OR=1.196, 95%CI: 1.005-1.422), and insufficient physical activity (OR=1.437, 95%CI: 1.155-1.787) were all associated with the prevalence of MS. Among the investigated subjects, 30.22% of them had one abnormal component, with hyperglycemia being the highest (54.44%); 24.25% of them had two abnormal components, with "hyperglycemia + hypertension" being the highest (33.30%); and 19.46% had three or more components, with "overweight/obesity + hyperglycemia + hypertension" being the highest (24.79%). Conclusions　The prevalence of MS in Hainan Province is on the rise, and effective lifestyle intervention measures are needed to reduce the risk of MS.

Objective: To evaluate the clinical efficacy of sinew-regulating bone-setting manipulations plus exercise therapy in treating chronic non-specific low back pain (CNLBP). Methods: A total of 65 CNLBP patients were divided into two groups by the random number table method. Thirty-three cases in the treatment group were intervened by sinew-regulating bone-setting manipulations plus exercise therapy; 32 cases in the control group were intervened by medium-frequency electrotherapy plus exercise therapy. Before and after treatment, visual analog scale (VAS), dynamic and static muscle endurance of low back, median frequency (MF) of surface electromyography (sEMG) and Oswestry disability index (ODI) were used to evaluate the low back function. The therapeutic efficacy was estimated after treatment. Results: The two groups each had 2 dropouts during the study. The total effective rate was 90.3％ in the treatment group versus 66.7％ in the control group, and the between-group difference was statistically significant (P<0.05). After treatment, the VAS score, dynamic and static muscle endurance of low back, MF of sEMG and ODI score all changed significantly in both groups (all P<0.05); all the items in the treatment group were significantly different from those in the control group (all P<0.05). Conclusion: Sinew-regulating bone-setting manipulations plus exercise therapy can effectively release pain in CNLBP patients, increase muscle endurance of the low back and improve the quality of life, and its therapeutic efficacy is more significant than that of medium-frequency electrotherapy plus exercise therapy.

OBJECTIVETo observe therapeutic effect and safety of acupuncture at the five-zangshu for treatment of perimenopausal syndrome (PMS).

METHODSForty cases of PMS were randomly divided into a treatment group and a control group, 20 cases in each group. The treatment group were treated with acupuncture at the five-zangshu and the control group with oral administration of Premarin tablets. The therapeutic effects and changes of Kupperman scores, and serum estradiol (E2), follicle stimulating hormone (FSH), luteinizing hormone (LH) levels before and after treatment were observed.

RESULTSThe total effective rate was 90. 0% in the treatment group which was better than 65.0% in the control group (P<0. 05). After treatment, serum E2 level significantly increased (P<0.01), with a significant difference between the two groups (P<0.05), and with a significant difference between the two groups in Kupperman symptom score index (MI) after treatment (P<0.05).

CONCLUSIONTherapeutic effect of acupuncture at the five-zangshu is better than that of Premarin for treatment of perimenopausal syndrome.

OBJECTIVETo explore the neuroprotective effect and mechanism of picroside II on extracellular regulated protein kinases1/2 (ERK1/2) signal transduction pathway in cerebral ischemia injuryrats. METHODS The middle cerebral artery occlusion (MCAO) model was established by inserting a monofilament into middle cerebral artery. Totally 96 successfully modeled Wistar rats were divided into the modelgroup, the treatment (picroside II) group, the Lipopolysachcaride (LPS) group, and the U0126 group according to random digit table. Each group was further divided into 3 subgroups, i.e. 6, 12, and 24 h sub-groups. Picroside II (20 mg/kg) was peritoneally injected to rats in the treatment group 2 h after ischemia.LPS (20 mg/kg) and Picroside II (20 mg/kg) were peritoneally injected to rats in the LPS group 2 h after ischemia. U0126-EtOH (20 mg/kg)and Picroside II (20 mg/kg) were peritoneally injected to rats in the U0126group 2 h after ischemia. Equal volume of normal saline was peritoneally injected to rats in the control groupand the model group. The neurobehavioral function was evaluated by modified neurological severity score(mNSS) test. The structure of neurons was observed using hematoxylin-eosinstaining (HE) staining. Theapoptotic cells were detected using terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. The expression of phosphorylated extracellular signal-regulated protein kinase1,2 (pERK1,2) in cortex was detected using immunohistochemistry (IHC) and Western blot.

RESULTSAfter cerebral ischemia injury neurological impairment score increased, the damage of neuron in the cortical area was aggravated, apoptotic cells increased in the model group as time went by. The expression of pERK1/2 increased more significantly in the model group than in the control group (P <0.05). The damage of neuron in the cortical area was milder, while apoptotic cells decreased, the expression of pERK1f2 obviously decreased more in the treatment group and the U0126 group (P < 0.05). The early damage of neuron in the cortical area was more severe, apoptotic cells and the expression of pERK12 were comparatively higher in early stage of the LPS group, but the expression of pERK1/2 was somewhat decreased in late stage.

CONCLUSIONSActivating ERK12 pathway could mediate apoptosis and inflammatory reactions of neurons after cerebral ischemia injury. Picroside II could protect the nerve system possibly through reducing activation of ERKI2 pathway, inhibiting apoptosis of neurons and inflammation reaction.
