Objective The aim of this study was to observe the effects of whole-body vertical vibration, treadmill exercise, genistein administration and estrogen injection on the uterus weight index and uterus histology as well as the ex-pression of glycogen synthase kinase ( GSK-3β) protein in the uterus of ovariectomized osteoporotic rats.Methods Sev-enty-two healthy 3-month old female SD rats were randomly divided into two groups by body weight:sham-operation group (Sham) and ovariectomized group (OVX).At 10 weeks after OVX operation, the OVX rats were randomly divided into the following five groups by body weight: OVX group, whole-body vertical vibration group (WBVV), treadmill exercise group ( TX) , genistein group ( G) and 17β-estrogen group ( E2 ) .Then they were treated with different methods according to the experiment design.At the end of experiment, the uterus weight was measured with an electronic balance.The uterus histology was observed with HE staining and the expressions of GSK-3βand P-GSK-3βproteins were detected by Western blot.Results Apart from E2 treatment, all the other three treatments did not increase the uterus weight and the thickness of endometrium compared with that in the OVX rats.Apart from genistein treatment, all the other three treatments increased the ratio of protein expression of P-GSK-3βto GSK-3βcompared with that in the OVX rats.Conclusions Both whole-body vertical vibration and treadmill exercise can stimulate the phosphorylation of GSK-3βin the uterus of OVX osteoporotic rats.However, genistein has no such stimulation effect.

OBJECTIVETo investigate the correlation between drinking behavior and polymorphism combination of extracellular superoxide dismutase (EC-SOD) and aldehyde dehydrogenase 2 (ALDH2) genes and oral squamous cell carcinoma.

METHODSThe genetic polymorphisms of EC-SOD and ALDH2 were analyzed by polymorphism-polymerase chain reaction technique in peripheral blood leukocytes of 750 oral squamous cell carcinoma cases and 750 non-cancer controls.

RESULTSThe frequencies of EC-SOD (C/G) and ALDH2 variant genotypes were 38.27% and 69.47% in oral squamous cell carcinoma cases and 21.07% and 44.40% in healthy controls, respectively. Statistical tests showed significant difference in the frequencies between the two groups (P < 0.01). The risk of oral squamous cell carcinoma with EC-SOD (C/G) was significantly higher than that of controls (OR = 2.32). Individuals carrying ALDH2 variant genotypes had high risk of oral squamous cell carcinoma (OR = 2.85). Combined analysis of the polymorphisms showed that percentages of EC-SOD (C/G)/ALDH2 variant genotypes in oral squamous cell carcinoma and control groups were 30.67% and 6.80%, respectively (P < 0.01). Individuals carrying EC-SOD (C/G)/ALDH2 variant genotypes had high risk of oral squamous cell carcinoma (OR = 8.13). The drinking rate of the case group was significantly higher than that in the control group (OR = 2.70). Statistical analysis suggested an interaction between drinking and EC-SOD (C/G) and ALDH2 variant genotypes, which increase risk of oral squamous cell carcinoma (OR = 25.00).

CONCLUSIONEC-SOD (C/G) and ALDH2 variant genotypes and drinking are the risk factors in oral squamous cell carcinoma, which could carry out a coordinated attack of oral squamous cell carcinoma.

Objective To determine whether the ?_2-adrenoceptor genetic single nucleotide polymorphisms are associated with atrial fibrillation.Methods A case-control study was performed on 218 subjects,including 58 subjects with lone atrial fibrillation,50 subjects with atrial fibrillation and essential hypertension,50 subjects with essential hypertension and 60 healthy controls.The ?_2-adrenoceptor polymorphisms at amino acids 16 and 27 were identified by allele specific polymerase chain reaction(PCR).Results The Gly/Gly genotype as well as the Gly16 allele at amino acids 16 was significantly more common in the atrial fibrillation group than in the non-atrial fibrillation group.But there was no significant differenece in the allele frequency or the genotype frequency of the Gln27 Glu polymorphism between the two groups.In addition,the difference in the distribution of polymorphisms at amino acids 16 and 27 between the four different observed groups was not significant either.Conclusion Gly16 polymorphism of the ?_2-adrenoceptor overrepresenting in the atrial fibrillation group seems to be associated with atrial fibrillation.

BACKGROUND:Osteoporosis is a bone metabolic disease that affects women more than men. Prevention and treatment of osteoporosis is becoming a serious medical problem because of the aging of the population. OBJECTIVE:To explore the effects of lithium chloride treatment on bone microarchitecture and bone marrow stromal cel differentiation of ovariectomized osteoporosis rats. METHODS:After ovariectomy, 28 of 30 healthy female Sprague-Dawley rats, 3 months old, were randomly divided into the folowing three groups: ovariectomizedin vivo group (9 rats), ovariectomizedin vitro group (10 rats), and lithium chloride group (9 rats). At the 11th week postoperatively, rats in the lithium chloride were intragastricaly injected with lithium chloride at a dose of 15 mg/kg, three times per week. After 8 weeks of treatment, the bone microarchitectures of the rat left femur in the ovariectomizedin vivo group and lithium chloride group were detected by micro-CT. The bone marrow mesenchymal stem cels were freshly isolated from the bone marrow of the bilateral femurs and tibia of rats in the ovariectomizedin vitro group. After 24 hours of inoculation, the cels were cultured in lithium chloride and divided into 0 mmol/L (control), 1 mmol/L and 5 mmol/L groups. At 6 and 8 days of culture, the medium was changed and lithium chloride with the corresponding concentrations was added. At 10 days of culture, western blot assay was adopted to detect protein expression of Runx-2, SP7 and PPARγ2. RESULTS AND CONCLUSION:(1) Compared with the ovariectomizedin vivo group, the volume density of trabecular bone, number of trabecular bone, and bone volume fraction in the lithium chloride group were significantly increased and the separation of trabecular bone was significantly decreased. However, no differences were seen in the thickness of trabecular bone and structure model index. (2) Lithium chloride at 1 and 5 mmol/L could increase the protein expression of Sp7 and Runx-2 in bone marrow stromal cels, but decrease the protein expression ofPPARγ2. These results indicate that lithium chloride may improve the microarchitecture of the trabeculr bone in ovariectomized osteoporosis rats through stimulating the osteogenic differentiation of bone marrow stromal cels.

Objective To evaluate the significance of suPAR,SCC-Ag in plasma and HPV16,18 in cervical secretion for monitoring pathogenetic condition and prognosis in patients with cervical cancer.Methods 206 cervical cancer patients blood and cervical secretion were collected.Plasma level of suPAR and SCC-Ag were measured by enzyme linked immunosorbent assay (ELISA) in health women and patients with cervical cancer.The expression of HPV16,18 of cervical secretion in control group and patients with cervical cancer were detected by fluorescence quantitative PCR.The correlations of the three indexes were analyzed.Results The plasma level of suPAR and SCC-Ag,the expression of HPV16,18 of cervical secretion in cervical cancer patients were obviously higher than those in health controls with statistical significance ((1.072 5±0.305 2) ng/ml vs (0.501 7±0.179 3) ng/ml,(0.980 6±0.162 7) μg/ml vs (0.261 4± 0.006 3) μg/ml and 53.89 ％ (90/167),46.15 ％ (18/39) vs 6.67 ％ (4/60),P ＜ 0.05).There was a positive correlation between plasma suPAR level and SCC-Ag level in invasive carcinoma of cervix patients (r =0.564,P ＜ 0.05).The plasma level of suPAR between in HPV16,18 positive group and in HPV16,18 negative group did not show difference (P ＞ 0.05).Conclusions In invasive carcinoma of cervix patients,there is a positive correlation between plasma suPAR level and SCC-Ag level.But it's not yet to conclude that plasma suPAR level of cervix invasive carcinoma patients is related to infection of HPV16,18.

Objective To explore the relationship uPAR in tissue and plasma of patients with cervical carcinoma and its clinical pathophysiological characteristics. Methods The preoperative plasma cancer tissue and its adjacent tissue in 42 cases of patient with ⅠB～ⅡA cervical carcinoma and the preoperative plasma and postoperative cervical tissue in 30 cases of patient with hysteromyoma were collected. Their uPAR were detected by ELISA. Results uPAR in the plasma of patients with cervical carcinoma was significantly higher than those in healthy controls and in patients with hysteromyoma. It was related to tumor invasive depth and lymph node metastasis and not related to tumor differentiation, uPAR in cancer tissue of patients with cervical carcinoma was significantly higher than those in normal cervical tissue. It was related to tumor differentiation and not to tumor invasive depth and lymph node metastasis. Conclusion uPAR in the plasma of patients with cervical carcinoma is related to invasion and metastasis, uPAR in the tissue is related to tumor differentiation.

Objective To investigate whether toll like receptor ( TLR) signaling pathways can in-crease the expression of IL-17 R in neuralglial cells , and if they can whether the increased IL-17 R is func-tional.Methods Experimental autoimmune encephalomyelitis (EAE) was induced in B6 mice by immuni-zation with an emulsion of myelin oligodendrocyte glycoprotein 35-55 ( MOG35-55 ) in complete Freund's adju-vant (CFA).The expression of Il17ra and Il17rc in the brains and spinal cords of mice with EAE were de-tected by real-time PCR.Luxol fast blue ( LFB) staining was performed to the spinal cord sections to detect tissue demyelination.Immunohistological staining against IL-17RA and CD3 were undertook to visualize IL-17RA+and CD3 + cells.Same approaches were also applied to immunized Rag1 -/- mice to figure out whether T cells infiltration is necessary for increasing IL-17RA expression in the central nervous system ( CNS) .Then B6 mice were immunized with incomplete Freund′s adjuvant ( IFA) plus different TLRs ago-nists to measure the expression of Il17ra in the brains and spinal cords by qPCR .The purified astrocytes , microglia and oligodendrocytes isolated from neonatal mice brains were cultured in vitro for two weeks , and then treated with different TLRs agonists .The expression of Il17ra at mRNA and protein levels in the cells were determined by qPCR and Western blot respectively .The astrocytes were treated with IL-17A and LPS individually or in the combination to detect the level of CCL 2, CXCL8 and IP-10 in the supernatant by ELISA.Results B6 mice with induced EAE showed significantly increased Il17ra expressions in the brain and spinal cord , which was also detected in immunized Rag1 -/-mice.Although no spinal cord demyeliza-tion and CD3 cells infiltration were detected in Rag1 -/-mice, significantly increased number of IL-17RA positive cells could still be visualized .In vivo TLRs agonist participated immunization and in vitro treatment of purified neuroglial cells demonstrated that TLRs agonists could directly evoke IL -17RA expression in the CNS or cultured astrocytes , microglia and oligodendrocytes with high efficiency .Both IL-17 A and LPS could stimulate astrocytes to secrete CCL2, CXCL8 and IP-10, however, a combined use of IL-17A and LPS fur-ther augmented the production of these chemokines to a large extend .Conclusion Taken together , we con-cluded that TLRs agonists could directly stimulate neuroglial cells to express IL -17RA which functionally re-spond to IL-17A by secreting chemokines .

Objective To evaluate the efficacy and superiority of intracardiac noncontact catheter mapping system for mapping and ablation of complicated arrhythmia.Methods 12 patients(9 males and 3 females,aged between 28 and 76 years) were included in this study.The characteristics of electrophysiological examination were as follows one was idiopathic ecotopic beats originated in right ventricular outflow tract(RVOT),two cases with idiopathic left ventricular tachycardia(ILVT),one atrial tachycardia(AT) of left atrium,two AT originated in right atrium,six atrial fibrillation(Afi) of left atrium.Among them,4 cases failed with conventional electrophysiological examination and radio frequency ablation(RFA),1 patient was reported recurrence.All patients were introduced 64 non-contact unipolar electrodes and ablation catheter to the same chamber via formal veins,reconstructed three-dimension geometry configuration,isopotential maps and analyzed the foci of reentrant activation and critical isthmus,then ablated the interested sites guided by noncontact mapping system.Results One idiopathic ectopic beat originated in RVOT near septum received segmental ablation.Two ILVT substrates located at left posterior-mid septum and left-posterior septum underwent segmental ablation.One AT of left atrium(LA) originated in right inferior pulmonary vein(RIPV) was given linear ablation between RIPV and mitral.One of the two AT from right atrium(RA) mapped the earliest activation in orifice of inferior cava vein and was given cricoid ablation;another AT originated in posterior wall of superior cava vein across crista terminal received linear lesion.One of the six Afi cases triggered by left atrial ectopic beats was given linear lesion between left superior pulmonary vein(LSPV) and right superior pulmonary vein(RSPV) during sinus rhythm;the other five cases mapped the reentrant origin site of Afi during persistent Afi rhythm received the catheter linear ablation,and the ablation lines respectively were created between RSPV and RIPV,LSPV and left inferior pulmonary vein(LIPV),LSPV and RSPV,LIPV and mitral isthmus.All patients succeeded and no obvious complication observed in operation and postoperation.None recurred during 2~26 month follow-up period.Conclusions It is safe and effective of intracardiac noncontact catheter mapping system for endocardium mapping and ablation of arrhythmia,especially for the clarity of electrophysiological mechanism of complicated arrhythmia and guiding RAF,which has potential clinical values.
