OBJECTIVETo observe the effects of electroacupuncture (EA) at "Sanyinjiao" (SP 6) on urodynamics indices in rats with overactive bladder (OAB) after cystostomy, and to explore its regulation mechanism on bladder function.
METHODSForty-eight Sprague-Dawley female rats which received cystostomy were randomly divided into a blank group (group A), a blank Sanyinjiao group (group B), a blank non-acupoint group (group C), a model group (group D), a model Sanyinjiao group (group E) and a model non-acupoint group (group F), 8 rats in each one. The model of OAB was established with 1% acetic acid solution perfused into the bladder in the group D, group E and group F. No treatment was given to the group A and group D. Acupuncture was applied at bilateral "Sanyinjiao" (SP 6) in the group B and group E, followed by EA after the arrival of qi. Acupuncture was applied at bilateral non-acupoint in the group C and group F, followed by EA with continuous wave, 2 Hz of frequency for 30 min. The treatment was given for continuous 5 urination cycles. The BL-420 E+ biological function experiment system was used to measure and record the changes of indices of bladder pressure and urodynamics.
RESULTSCompared with the group A, the bladder capacity and urine output in the group B were significantly increased (both P<0.05), and the urination rate was increased in the group C (P<0.05); the differences of each index between group C and group B were not statistically significant (all P>0.05). Compared with the group D, the capacity pressure, bladder capacity, detrusor pressure, urinary output and urination rate in the group E were all increased (all P<0.05). Compared with the group F, the capacity pressure and detrusor pressure in the group E were increased (both P<0.05).
CONCLUSIONThe EA at "Sanyinjiao" (SP 6) could significantly improve urine function in rats with OAB after cystostomy, but its regulation effect on urination is not obvious in rats with non-OAB.

A hydroponic experiment carried out to study the effect of five Cd levels on growth and photosynthesis of two tomato cultivars showed that the addition of 0.1 micromol/L Cd induced a slight increase in plant height of Hezuo 903 and the SPAD (the Soil-Plant Analyses Development) value of the 2 cultivars. However, at higher Cd levels, i.e., 1 and 10 micromol/L, root length and volume, plant height, and SPAD value were all significantly reduced. On an average of the 2 cultivars, exposure to 1 and 10 micromol/L Cd for 33 d reduced plant height by 18.9% and 46.4% and SPAD value by 11.2% and 31.6%, compared with control, respectively. Similarly, root length was reduced by 41.1% and 25.8% and root volume by 45.2% and 63.7%, respectively. The addition of Cd in the growth medium also had significant deleterious effect on net photosynthetic rate (Pn) and intracellular CO(2) concentration (Ci), with Pn being reduced by 27.2% and 62.1% at 1 micromol/L and 10 micromol/L Cd treatments compared to the control, respectively, while Ci increased correspondingly by 28.4% and 39.3%.

OBJECTIVETo explore the effect of endotoxin concentration in dwellings on the prevalence of atopic asthma in children.
METHODSStandardized questionnaires of asthma were distributed to the parents of 2986 school children aged between 8 and 12 years and endotoxin content in children's mattress was measured by a kinetic limulus assay. A radioallergosorbent technique--fluorescence enzyme immunoassay (RAST-FEIA) was used to measure the level of specific IgE in serum.
RESULTSComplete data was available for 904 children with males more than females. There were both negative associations seen between endotoxin levels and both atopic asthma (OR = 0.48, 95% CI: 0.32-0.72, P < 0.05) and atopic sensitization (OR = 0.65, 95% CI: 0.49-0.94, P < 0.05) but not with non-atopic asthma and wheeze. Comparing with normal people, patients with atopic sensitization, atopic wheeze and atopic asthma had a higher levels of endotoxin (M-W U: 15 138.0, P < 0.01, M-W U: 4858.0, P < 0.01, M-W U: 4041.0, P < 0.01).
CONCLUSIONExposure to endotoxin in early lives of children might have a protective effect on atopic asthma and sensitization.

Objective To explore the relationship between expression of P-glycoprotein (P-gp), a product of multidrug resistance (MDR) gnne, in the peripheral blood of children with intractable or newly diagnosed epilepsy for drug resistance. To establish a marker of drug resistance. To evaluate the therapeutic effect of flunarizine in the treatment of intractable epileptic patient with or without overexpression of P-gp. Methods The expression of P-gp in peripheral blood were investigated in 86 epileptic children (41 in intractable epilepsy group, 45 in newly diagnosed epilepsy group) and 44 healthy children (controlled group) by flow cytometry. Intractable epileptic patients with or without overexpression of P-gp were given flunarizine 2.5 - 5 mg, po, qn, for 3 months and followed up. Results Overexpression of P-gp were found in 23 (56.1%) patients of intractable epilepsy group, in 10 (22.2%) patients of newly diagnosed epilepsy group and three (6.8%) children of the controlled. In intractable epilepsy group, 17 out of 23 cases (73.9%) patient with overexpression of P-gp became tolerant to antiepileptic drugs, while 3 out of 18 cases (16.7%) patient without expression of P-gp became tolerant to antiepileptic drugs, and there was significant difference between them (P < 0.01) . In the newly diagnosed epilepsy group, seven out of 10 cases (70%) with overexpression of P-gp became intractable epileptic patient and three out of 35 eases (18.6%) without expression of P-gp became intractable epileptic patient, there was significant difference between them (P < 0.01). Twenty patients of intractable epilepsy group were given flunarizine for three months, 11 of 17 patients with P-gp overexpression and 1 of 3.patients without P-gp expression were effective. When reexamined, P-gp expression in 6 out of 11 patients became negative. Conclusions It is suggested that overexpression of P-gp in the peripheral blood of intractable epileptic patients might be a significant marker of drug resistance. Newly diagnosed epileptic patients with overexpression of P-gp may develop intractable epilepsy. P-gp was a predictable marker of intractable epilepsy. Flunarizine could be a choice in treatment of intractable epilepsy with overexpression of P-gp. The antiepileptic mechanism of flunarizine may involve in reversing of P-gp.
