Objective To investigate the potential role of FoxP3-expressing CD4+CD25+ regulatory T cells in children with asthma.Met-hods Intracellular 3-colour flow cytometry and real time PCR were used to assess the expression of FoxP3 in peripheral blood mononuclear cell(PBMC)of asthma,repectively.Results There were similar frequencies of CD4+ CD25+ T cells in peripheral blood of asthma patients and healthy subjects.However,the percentage of CD4+CD25high and CD4+CD25+FoxP3+ in asthma group were lower than those in healthy subjects(Pa

Aim To observe the influences of dexmen-detomidine on the spontaneous contraction of duodenal smooth muscle of rabbits in vitro and explore the mech-anisms.Methods The rabbits ( male or female ) were stunned and the duodenums were isolated .The sam-ples of duodenal segments were connected with tension transducer , which were then put into oxygen saturation Krebs-Henseleit ( K-H) solution .The influences of dex-mendetomidine on amplitude ( AM ) and frequency ( FR ) of duodenal smooth muscle were recorded by BL-420 F biological signal processing system .The cu-mulative dosing method was used to observe the differ-ent concentrations of dexmedetomidine on duodenal smooth muscle spontaneous contraction .Glibenclamide ( Gli) was added to K-H solution before dexmendeto-midine.In the calcium-free K-H solution, calcium chloride and rynodine were added before dexmendeto-midine.The mechanisms of dexmendetomidine were studied .Results ① Dexmendetomidine reduced the amplitude of spontaneous contraction of duodenal smooth muscle in rabbits in a dose-dependent manner ( P<0.05 or P<0.01 ) , while the frequency was not obviously influenced ( P >0.05 ) .② Gli ( P <0.05 ) partly abolished the inhibitory effects of dexmendetomi-dine on duodenal smooth muscle .③ Dexmendetomi-dine inhibited the contraction of duodenum smooth muscle induced by calcium chloride ( P <0.05 ) and rynodine ( P<0.05 ) application into calcium-free K-H solution.Conclusion Dexmendetomidine inhibits the spontaneous contraction of duodenal smooth muscle of rabbits in vitro.The mechanisms may be related to ac-tivating ATP sensitive potassium channels , inhibition of the extracellular calcium influx via cell membrane and intracellular calcium release via sarcoplasmic reticulum in duodenal smooth muscle .

ObjectiveTo observe the effect of pulsed electromagnetic fields (PEMFs) on bone mineral density (BMD) of spinal cord injuried (SCI) patients. MethodsThe PEMFs group was composed of 12 SCI patients received regular PEMFs treatment as the treatment group, 12 SCI patients treated without PEMFs were as the control group.BMD of total proximal femur, Ward's trigonum and great trochanter of all patients were detected by dual-energy X-ray absorptiometry before and after treatment.ResultsBMDs of total proximal femur and great trochanter of patients of the treatment group were a little increased after PEMFs treatment, with no significant difference (P>0.05), but BMD change was significantly different compared with the control group (P<0.05～0.01).ConclusionPEMFs treatment along with routine exercise may help to reduce the loss of bone after SCI.

OBJECTIVETo study the distribution of Chinese syndrome type in patients with primary osteoporosis (POP) and its relationship with bone fracture.

METHODSMaterials of 180 POP patients who visited Xiyuan Hospital were investigated, their incidence of bone fracture observed and Chinese syndrome types differentiated. And the outcomes were analyzed statistically using SPSS 13.0.

RESULTSThe morbidity of POP in female was higher than that in male, the sex ratio (M/F) being 1:3 (41 cases vs 139 cases). Chinese syndrome type distribution in the POP patients was: Shen-deficiency syndrome (SDS) type in 7.8% patients (14 cases), Pi-Shen deficiency syndrome (PSDS) type in 21.7% (39 cases), Pi-Shen deficiency and blood-stasis syndrome (PBS) type in 70.6% (127 cases), the difference of partition between types was significant (P < 0.05). Bone fracture had occurred in 12.78% (23 cases) of patients, the occurrence in patients with different types was 4.34%, 17.39%, and 78.26%, respectively. Incidence of bone fracture was also different in patients of various age section, being 5.3% in 50-59 years section, up to 15.0% in 60-69 years section (P < 0.05), and down to 12.24% in 70-80 years Section.

CONCLUSIONThe risk of bone fracture in POP patients of PBS type is higher than that in those with SDS or PSDS type, and 60-69 years is the high risk age section of bone fracture in POP patients.

OBJECTIVETo observe the preventive effect different compatibilities of Ramulus Cinnamomi (RC) and peony in Guizhi Decoction (GD) on diabetic cardiac autonomic neuropathy (DCAN).

METHODSTotally 60 male rats were randomly divided into 5 groups, i.e., the blank control DM group, the model group, the methycobal group, the 1:1 (RC/peony) Guishao group, the 2:1 Guishao group, and the 1:2 Guishao group, 10 in each group. Rats were pretreated with corresponding drugs for 1 week, and then induced diabetes by intraperitoneal injection of STZ. Drugs were administrated by gastrogavage for 4 more weeks after STZ-injection. Enzyme-linked immunosorbent assay (ELISA) was employed to detect levels of tyrosine hydroxylase (TH), choline acetyltransferase (CHAT), nerve growth factor. (NGF), and ciliary neurotrophic factor (CNTF) in myocardial homogenates.

RESULTSAfter 4-week modeling, body weight (BW) was obviously lower, but blood glucose (BG) was higher in STZ rats than in rats of the blank control DM group. There was no statistical difference in BW or BG among the 5 groups (P >0.05). Compared with the blank control group, TH, TH/CHAT, and NGF in left ventricle and ventricular septum increased, CHAT and CNTF increased in the model group (P < 0.05, P < 0.01). Compared with the model group, TH and TH/CHAT in left ventricle decreased (P < 0.05, P < 0.01), CNTF in left ventricle increased (P < 0.05), CHAT in left ventricle and ventricular septum increased (P < 0.05, P < 0.01) in the methycobal group. TH and TH/CHAT in left ventricle and ventricular septum decreased, CNTF in left ventricle and ventricular septum increased (P < 0.05, P < 0.01), CHAT in left ventricle and ventricular septum increased (P < 0.01), NGF in ventricular septum decreased (P < 0.01) in the 1:1 Guishao group. TH/CHAT in left ventricle decreased (P < 0.01), CHAT and CNTF in left ventricle and ventricular septum increased (P < 0.05, P < 0.01) in the 1:2 Guishao group. Compared with the methycobal group, CHAT in left ventricle decreased, TH and TH/CHAT in left ventricle increased in the 2:1 Guishao group (P < 0.05, P < 0.01). TH and TH/CHAT in ventricular septum decreased (P < 0.05), CHAT and CNTF in left ventricle and ventricular septum increased (P < 0.05, P < 0.01) in the 1:1 Guishao group. Compared with the 1:2 Guishao group and the 2:1 Guishao group, CHAT in left ventricle increased, TH/CHAT in left ventricle decreased, TH and TH/CHAT in ventricular septum decreased, CHAT in ventricular septum increased, CNTF in left ventricle and ventricular septum also increased in the 1:1 Guishao group (all P < 0.01).

CONCLUSIONSSTZ model rats had autonomic neural injury, manifested as lowered vagal nerve activity and hyperactive sympathetic nerves. GD could effectively suppress hyperactive cardiac sympathetic nerves and protect the vagus. Besides, GD (1:1) showed the optimal effect in regulating the balance of cardiac autonomic nerves and could be used in early prevention of DCAN.

The effect of kaolinite on the enzymatic chiral hydrolysis of methyl dichlorprop enantiomers ((R,S)-methyl-2-(2,4- dichlorophenoxy) propanoic acid, 2,4-DPM) was investigated using chiral gas chromatography. Compared with the control without kaolinite, the enantiomeric ratio (ER) increased from 1.35 to 8.33 and the residual ratio of 2,4-DPM decreased from 60.89% to 41.55% in the presence of kaolinite. Kaolinite likely had emotion influence on lipase activity and its enantioselectivity. Moreover, the amount of kaolinite added was also found to be a sensitive factor affecting the enantioselective hydrolysis of 2,4-DPM. Fourier transform infrared (FTIR) spectroscopy studies of the interaction of lipase with kaolinite provided insight into the molecular structure of the complex and offered explanation of the effects of kaolinite on enzymatic hydrolysis of 2,4-DPM. Spectra showed that the effect of kaolinite on the hydrolysis of 2,4-DPM was affected by adsorption of lipase on kaolinite and changes of adsorbed lipase conformation, which led to the modified enantioselectivity.
