Aim To investigate and evaluate the effect of ligustrazine on the expression of scavenger receptor type AI, the human ?-interferon activation site (GAS) elements regulatory systems of SR-AI expression wasfirst established in the Xenopus oocytes. Methods A plasmid, in which the human SR-AI gene was constructed downstream from the GAS elements, was microinjected into the nucleus of Xenopus oocytes. The oocytes then were cultured in the smooth muscle cell conditioned medium (SCM), In which the cell were cultured with the treatment of oxLDL for 2 days. In the other groups, the oocytes were treated with SCM containing the nature medicines ligustrazine, and the positive control drug ?-interferon respectively. Results The results demonstrated that SCM could upregulate the expression of SR-AI in this system, this action was suppressed by ligustrazine and ?-interferon. Conclusion Similar to the action of ?-interferon, ligustrazine can prevent the over-expression of SR-A induced by oxLDL, via their effect on the GAS elements regulatory pathway.

Objective To determine the effects of practicing a simplified 24 movement form of Tai chi on the level of inflammatory cytokines and the quality of life of type 2 diabetes patients. Methods A group of type 2 diabetes patients practiced a simplified 24 movement Tai chi routine 60 min/d, 3 d/week for 6 months. Plasma glu-cose and insulin concentration were monitored. The plasma level of IL-6, IL-18, sCD40L, hsCRP and HBAc1 were measured. Changes in the patients' quality of life were also measured by using the SF-36. Results Serum IL-6,IL-18, hsCRP and sCD40L levels were all significantly lower compared with a control group. Significant quality of life improvements were seen in the Tai chi group compared with the controls. Significant reductions were seen in blood pressure, glycated haemoglobin, glucose, insulin resistance and urinary albumin. Conclusions These results sug-gest that regular Tai chi practice can prevent complications and improve the quality of life of diabetes sufferers through glyeaemic control and down-regulating inflammatory cytokine levels.

Up to now, a variety of microRNAs have been found in a number of studies, that specifically expressed in retinal neuroepithelial, lens, cornea and retinal pigment epithelium, in which miR-126 plays a certain role in the proliferation of tumor cells, the development of thymus lymphocytes and cardiovascular diseases.Some researches show that miR-126 has certain correlations with the formation of corneal neovascularization, the development of diabetic retinopathy, and the immune system related eye disease.In this paper, the current miR-126 in the role of eye disease mechanism and research progress were reviewed.

The nucleic acid fragment of porcine circovirus type 2(PCV2)was amplified using PCR from the tissues of a domesticated wild boar with suspected postweaning multisystemic wasting syndrome(PMWS).The sample were then inoculated into the Dulac cells and passaged for 8 generation.The 4 nucleic acid fragments covered the complete genome for PCV2 were obtained by over-lapping PCR and sent to sequence.The sequence of genome was compared with other 9 strains originated from piglets in the same area.The result showed that these strains were in high homology.

Background Chemical crosslinking agent can be used to strengthen the intensity of sclera tissue,but the intensity of the sclera may be influenced by different crosslinking methods.Objective The aim of this study was to compare the effectiveness of collagen crosslinking on porcine sclera between whole-eye crosslinking method and scleral strip crosslinking method.Methods Whole-eye crosslinking or sclera strip crosslinking was performed on 70 fresh porcine eyeballs in five groups using 1％ genipin,1％ glutaraldehyde or PBS respectively for 40 minutes.After crosslinking,10 sclera strips with l0 mm×4 mm from the temporal lateral were prepared in every group for the stress-strain measurement using a Instron5848 microtester,and the other 4 scleral strips in each group were extracted for the thermal shrinkage temperature test.Results Biomechanical property test reveled that the elastic modulus value of sclera strips reduced by 70.0％-82.8％ in the whole-eye crosslinking method group compared with scleral stip crosslinking method group after treated with 1％ genipin ((8.98 ± 1.81) MPa vs.(10.85 ± 1.83) MPa,t =3.375,P =0.003)) and 1％ glutaraldehyde((12.78 ±2.91) MPa vs.(18.25 ±5.16) MPa,t =4.007,P =0.001)) ;The tensile stress of whole-eye crosslinking method group was 54.9％-90.1％ of scleral stips method group,showing significant decline after corsslinked of whole-eye in 5％,10％,15％ and 20％ strain conditions (all P ＜ 0.05).Thermomechanics test showed that the thermal shrinkage temperature was lower in the whole-eye crosslinking group compared with scleral stip crosslinking group after treated with both 1％ genipin ((68.8 ±0.9)℃ vs.(74.8± 1.3)℃,t=11.129,P=0.000)) and 1％ glutaraldehyde((73.3±0.9)℃ vs.(79.3±1.3)℃,t=11.112,P=0.000)).Conclusions Different crosslinking methods have an influence on the efficacy of collagen crosslinking on porcine sclera.Sclera strip crosslinking offers a better crosslinking intensity for selera.

Objective To investigate the prevalence of hypothyroidism during the second trimester and its relationship with thyroid peroxidase antibody (TPOAb). Methods Two thousand one hundred and forty one pregnant women whose gestational age between 14 to 28 weeks,accepted their prenatal care at the outpatient clinic of International Peace Maternity & Child Health Hospital from March 1,2010 to July 31,2010 were enrolled into this study. Serum TPOAb,thyroidstimulating hormone (TSH) and free thyroxine (FT4) of these women were detected. Logistic regression model was used to analyze the risk factors of subclinical hypothyroidism and positive TPOAb,while Spearman rank correlation was used to analyze the relationship between the levels of TSH,FT4 and TPOAb. Results (1) Subclinical hypothyroidism was detected in 13.36％ (286/2141) patients. Isolated maternal hypothyroxinemia occurs in 0.14％ (3/2141) of pregnant women.No overt hypothyroidism patient was detected and 6.26％ (134/2141) of all pregnant women exhibited positive TPOAb(≥50 U/ml).(2) Positive rate of TPOAb in subclinical hypothyroidism group,isolated maternal hypothyroxinemia group and normal thyroid function group was 13.64％ (39/286),0/3 and 5.06％ (86/1701) respectively,and there was difference among the three groups (x2 =30.82,P＜0.01).The positive rate of TPOAb did not relate to fetal gender,maternal age,gestational age,gravidity and parity.(3) TPOAb had positive relationship with TSH level (r=0.12,P＜0.01),while did not relate to FT4 level (r=-0.04,P=0.09). (4) Positive TPOAb (OR 3.18,95％ CI:2.10-4.83,P＜0.01) and gravidity (OR=1.21,95％ CI:1.02-1.43,P=0.030)were risk factors of subclinical hypothyroidism. Conclusions Hypothyroidism is common during the second trimester. It is necessary to screen TPOAb in pregnant women as TPOAb is an independent and important predictor of subclinical hypothyroidism.

Objective To evaluate the effect of pelvic muscle exercise on quality of sexual life after panhysterectomy surgery.Methods A retrospective review was made on 166 patients with integrated follow-up documents,after their panhysterectomy surgery caused by benign diseases.A normal nursing care was provided to the control group (n=81); while an additional pelvic muscle exercise was performed on the normal care basis,to those in the experimental group (n=85).Finally,a questionnaire on sexual life quality was made at the sixth month,ninth month,and twelfth month respectively,using a repeated measure ANOVA to analyze the data of each dimension and the whole score.Results Significant differences revealed both on the whole score and dimensions of the sexual satisfaction,sexual communication,sexual anxiety and sexual reaction,in different time sites.However,no difference was found in sexual attitude and body image.Besides,a cross interaction was found between time and intervention,where intervention presented different effects.Conclusions Pelvic muscle exercise is recommended in gynecological continuing nursing care to facilitate the recovery of sexual life after panhysterectomy surgery.

Objective To explore the impact of chronic cough on children’s life quality, and to observe their life quality after drugs and psychological intervention. Methods One hundred 9 to 12 years old children with chronic cough were randomly selected. The drugs and psychological intervention were administrated. The children had been follow-up. The children’s quality of life was assessed by“Inventroy of Subjective Life Questionnaire”before and after treatment. Meanwhile 100 healthy children were randomly selected as a control group. Results With the prolonged treatment, the recovery rate and effective rate in children with chronic cough increased. Before the treatment, the scores of family life, peer interaction, self cognitive, experience of depression, experience of anxiety, cognitive and emotional component, and overall satisfaction were significantly lower in children with chronic cough than those in healthy children (P<0.05). After the treatment, the scores of family life, peer interaction, self cognitive, experience of depression, experience of anxiety, physical experience, cognitive and emotional component, and overall satisfaction were significantly improved in children with chronic cough (P<0.05), even the scores of physical experience and emotional component were significantly higher in children with chronic cough than those in healthy children (P<0.05). Conclusions The quality of life in children with chronic cough decline, however, drug and psychological intervention can improve their quality of life.

Objective To investigate the feasibility and safety of transvaginal endoscopic cholecystectomy.Methods The clinical data of 88 female patients who underwent cholecystectomy at the Qilu Hospital of Shandong University from May to November, 2009 were retrospectively analysed. Among all the patients, 32 received transvaginal endoscopic cholecystectomy ( NOTES group) and the remaining 56 patients received laparoscopic cholecystectomy (LC). Thirty-two patients who received LC at the same period were selected (LC group)acccording to age, body mass index, type and severity of disease to conduct a matched case-control study. The differences in time span of postoperative pain, anodyne dose, enterokinesia recovery time, operation time, out-ofbed activity time, average hospital stay and hospitalization expenses between the two groups were compared using the paired t test. Results Cholecystectomies were successfully carried out for all the patients. The intraoperative blood loss, operation time, degree of pain, anodyne doses, enterokinesia recovery time, out-of-bed activity time,average hospital stay and hospitalization expenses were (5.7 ± 1.5 ) ml, ( 76 ± 27 ) minutes, 2.2 ± 0.6, ( 10 ±6) mg, (25±5) hours, (9±3) hours, (2.1 ±1.2) days and (1.12±0.34) ×104 yuan in NOTES group, and they were ( 13.9 ± 3.1 ) ml, (38 ± 16) minutes, 6.7 ± 1.5, (28 ± 8) mg, (45 ± 8) hours, (26 ± 6) hours,(4.3 ± 2.1 ) days and ( 1.54 ± 0.18 ) × 104 yuan in the LC group. There were significant differences between the two groups (t = 5.098, - 4.712, 2.417, 3.203, 3.089, 4.136, 4.786, 3.917, P ＜ 0.05 ).
