OBJECTIVETo study the function of the chalcone synthese gene introns in Scutellaria baicalensis, and clarify preliminarily their role in abiotic stress.

METHODThe CHS introns with specific primers were cloned and bioinformatic method was applied to predict the cis-elements in the intron of CHS. The introns were subcloned into binary vector, pCAMBIA-1301 before being transferred to tobacco. Then the activity of GUS of the transgenic tobacco seeds was analyzed.

RESULTSeven cis-elements were found in the introns. Under the dark and high temperature GUS expression rose at the first (3 h), but then declined (9 h). ABA and MeJA regulated insignificantly the GUS activity in normal temperature; treatment of 10% PEG induced GUS expression.

CONCLUSIONCHS introns could be play a role in the regulation of S. baicalensis phenylpropanoid biosynthetic pathway.

OBJECTIVETo explore the effect of Bushen Gujin Recipe (BGR) on serum and synovial expression of interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-α) in knee osteoarthritis (KOA) model rabbits.

METHODSTotally 36 8-month-old healthy male New Zealand white rabbits were randomly divided into 4 groups, i.e., the normal control group, the model group, the Western medicine group (Meloxicam, at the daily dose of 6 mg/kg), and the TCM group (BGR, at the daily dose of 53 g/kg), 9 in each group. Modeling was performed in all rabbits except those in the normal control group by using Hulth A method. All medication was performed for 8 consecutive weeks. Contents of IL-1 and TNF-α were detected using ELISA from serum, partial synovial tissue of the front knee joint, cartilage and subchondral bone of the medial femoral condyle.

RESULTSThe joint space became narrowed in the Western medicine group, ranging between the model group and the TCM group. The articular surface was rough with obvious osteophytes. The joint space was slightly narrower in the TCM group; the articular surface was slightly rough with mild osteophytes. Compared with the normal control group, contents of IL-1 and TNF-α in serum and synovial increased in the model group (P < 0.01). Compared with the model group, contents of IL-1 and TNF-α in serum and the synovial fluid decreased in the two treatment groups (P < 0.01). There was no statistical difference in contents of IL-1 and TNF-α between the Western medicine group and the TCM group.

CONCLUSIONBGR promoted the synthesis of cartilage matrix and carti- lage repair through inhibiting the secretion of IL-1 and TNF-α, and prolonging cartilage degeneration.

Objective To study the activated status of insula during the performance of word generation task, and to explore the function of different part of insula with functional MRI (fMRI). Methods Twenty-eight subjects were recruited in this study (male 15, female 13), all of them underwent block-designed fMRI with word generation tasks and resting-state scan. SPM 5 and REST 1.3 were used to process the data. Bilateral anterior insula and posterior insula were selected as seeds to calculate the connectivity coefficiency with other voxels, and differences between the anterior and the posterior insula were compared. Results Bilateral anterior insula was significantly activated, while bilateral posterior insula was significantly deactivated. The functional connectivity areas with left anterior insula included right anterior insula, right posterior insula, supplementary motor area (SMA), left superior temporal gyrus, left middle frontal gyrus, left superior frontal gyrus, left inferior parietal lobe, middle cingulate gyrus, right striatum and right inferior frontal gyrus. The functional connectivity areas with left posterior insula included right posterior insula, left anterior insula, right superior temporal gyrus, middle cingulate gyrus, right precentral gyrus and right striatum. The functional connectivity areas with right anterior insula included SMA, left inferior frontal gyrus, right inferior parietal lobe, left inferior parietal lobe, left superior temporal gyrus, right precentral gyrus, right striatum, middle cingulate gyrus, left middle frontal gyrus, left striatum, right middle frontal gyrus, right inferior frontal gyrus and left transverse temporal gyrus. The functional connectivity areas with right posterior insula included right precentral gyrus, left superior temporal gyrus, left anterior insula, left posterior insula, right supramarginal gyrus and middle cingulate gyrus. Conclusion Anterior insula and posterior insula are functionally connected with different areas, and concerned with the language function in different manners. Left lateral anterior insula may play an important role in the language function.

Objective To investigate the differences of 10-week running and badminton exercise on bone mineral density(BMD) and related biochemistry markers in female university student.Methods Sixty healthy female university students were randomly divided into running(R) group,badminton(B) group and control group.Apart from basic physical education class,the R and B group participated in running and badminton exercise respectively(30-40 min per time,3 times per week,10 weeks).Before and after test,the BMD of lumbar vertebra and femurs,the serum level of estradiol(E2) and testosterone(T),the serum level of alkaline phosphatase(ALP)and tartrate resistant acid phosphatase(TRACP) were all detected.Results After test,there were no significant difference on BMD in all parameters of the three groups(P>0.05).After test,the serum level of E2 and TRACP in R group were significant higher than those in control group(t=-3.351,t=-0.854,P<0.05),the serum level of Ca was significant lower than that in control group(t=-1.852,P<0.05).Comparison between before test and after test,the serum level of E2 and P increased significantly in R group(P<0.05),while the serum level of TRACP decreased significantly(P<0.05),the serum level of P and Ca increased in the three groups(P<0.05),while no differences were seen in the other parameters.Conclusion The effects of running exercise on serum level of E2 and TRACP were higher than badminton exercise.

Objective To observe the dilated cardiomyopathy ( DCM ) in non-Keshan disease areas in Shandong Province and assess scientifically the effectiveness of prevention and control measures on Keshan disease (KSD). Methods According to the scheme of DCM condition survey of our country in non-Keshan disease areas, seven representative counties(cities, areas) were chosen by their similarities in natural environment, production and life style to KSD areas; one or two townships ( towns ) were chosen in each county ( city , area ); one village was selected as a survey point in each township ( town ) . In each survey point , about four hundred and twenty natural populations were checked by asking detailed history, physical examination, and electrocardiography (ECG) tracings, and suspicious people were taken chest X-ray examination and cardiac ultrasound(UCG). The samples of inside and outside environmental were collected in partial residents and the selenium contents were detected by 2,3-diaminonaphthalene fluorometric method. At the same time the income, food of inhabitant and other basic information were collected. Results ① In 13 survey villages, sixty-four hundred and sixty-three residents were surveyed and 2 DCM cases and 111 similar potential KSD cases were detected, the detection rate was 1.75%(113/6 463). ② Sixty-four hundred and sixty-three residents were traced by ECG and the incidence of abnormal ECG was 20.4%(1 318/6 463), and sinus bradycardia, T-wave changes, sinus tachycardia, ST-T changes, occasional ventricular beating earlier, complete right bundle branch block, left anterior branch block, room premature beat, left ventricular high voltage, auriculo-ventricular block, et al were common. ③Samples of hair(260), wheat(260), corn (240) and soil (104) were collected, and the selenium contents were (0.353 ± 0.082), (0.035 ± 0.009), (0.024 ± 0.008) and (0.164 ± 0.019)mg/kg, respectively. Annual per capita income of each survey point was 2 500-8 670 yuan, and the residents’ main staple food was flour. Conclusion The results of DCM condition in non-Keshan disease areas of Shandong Province are stable and have provided a scientific basis for drawing up the national standard of eliminating KSD.

Objective To investigate the effect of periurethral injection of insulin-like growth factor(IGF)-Ⅰ on the expression of IGF-Ⅰ and IGF-Ⅱ mRNA during regeneration period following urethral sphincter muscle injury in female rats. Methods Model of urethral sphincter muscle injury was made in female virgin SD rats (n=50) by intravaginal balloon inflation. Then the rats were divid-ed randomly into treatment group (n= 25) and control group (n= 25), treatment group accepted peri-urethral injection of 1.0μg human IGF-Ⅱ to the middle urethral muscle, control group accepted nor-mal saline injection. Five rats in each group were sacrificed at 2, 4, 6, 8, 14 day respectively and the whole urethra specimens were processed for RT-PCR to detect the expression of IGF-Ⅰ ,Ⅱ mRNA. A normal control group (n = 5) was set without intravaginal balloon inflation and injection. Results The expression of IGF-Ⅰ mRNA in control group increased at day 4, 6, 8, 14, the IGF-Ⅰ/β-actin ra-tios were 0. 58±0.15, 1.73±0.31, 2.30±0.29, 0. 46±0. 06. The expression of IGF-Ⅰ mRNA in treatment group increased at all time points, as 0. 69±0.21, 1.45±0.17, 2.25±0.45, 2.90±0.49, 1.92±0. 31. The difference was significant on day 4, 14(P<0.01), and day 8 (P<0.05) compared with the control group. The expression of IGF-Ⅱ mRNA in control group increased at day 4, 6, 8, as 0.42±0. 14, 1.51±0. 59, 1.31±1.04. The expression of IGF-Ⅱ mRNA in treatment group in-creased at day 4, 6, 8, 14, as 1.04±0.23, 1.94±0.29, 1.75±0.41, 0. 81±0.15. The significant difference was noted on day 4 (P<0. 01)compared with the control group. No expression of IGF-Ⅰand Ⅱ mRNA in the normal control group. Conclusions The expression of endogenous IGF-Ⅰ and IGF-Ⅱ mRNA was up-regulated by periurethral injection of IGF-Ⅰ during regeneration period follow-ing urethral sphincter muscle injury in female rat. Our findings suggest that IGF-Ⅰ facilitates the re-generation of the urethral muscles and may play a role in treatment of stress urinary incontinence in-duced by urethral sphincter muscle dysfunction.
