Objective:To investigate the psychological state of the patients from Wenchuan Earthquake treated in some local and military hospitals.Methods:We consulted the general data and pathogenetic condition of 116 patients from the earthquake-stricken area of Sichuan,studied their mental health using the Hamilton Anxiety Scale(HAMA) and investigated their psychological changes during the rescue and treatment with self-designed questionnaires.Results:The earthquake patients manifested obvious anxiety in the initial stage and their mental health was gradually improved towards the end of the rescue process.Conclusion:Wenchuan Earthquake caused great psychological trauma in the earthquake patients,for whom timely psychological intervention is of utmost importance.

Objective To study the expressions of Cx43,CD105 and VEGF in HBV related HCC tissues and the relationships between Cx43 expression and recurrence and prognosis after cancer radical resection in HCC patients stratified by serum AFP levels. Methods The expressions of Cx43,CD105,VEGF in 234 HBV related HCC tissues were examined by tissue microarray and two-step methods of PV-6000 of immunohistochemistry and the expressions of Cx43 in 20 frozen HCC specimens were examined by RT-PCR. Results Cx43 in HCC tissues was positive as examined by both immunohistochemistry and RTPCR methods.Positive Cx43 expression is correlated with lower early recurrence ( Log Rank P =0.001 ),longer disease free survival (Log Rank P =0.026 ) and overall survival( Log Rank P =0.000 ) as showed by the Kaplan-Meier analysis in patients with AFP ＜ 400 μg/L. The expression of Cx43 is an independent prognostic factor.The positive expression of Cx43 related with lower positive expression of CD105 and VEGF (P =0.018,0.023 ),and correlated with histological differentiation (P =0.002),the number of focus (P =0.033 ),blood vessel tumor embolism ( P =0.029 ). Conclusions The expression of Cx43 is correlative with the expression of CD105 and VEGF,and is predictive of HCC early recurrence and poor prognosis after radical hepatectomy in HBV related HCC patients with serum AFP ＜ 400 μg/L.

Epithelial-to-mesenchymal transition (EMT) plays a critical role in cancer metastasis,and is relevant to the inflammatory microenvironment.Lipopolysaccharide (LPS),a cell wall constituent of gram-negative bacteria,has been reported to induce EMT of cancer cells through TLR4 signal.We previously reported that LPS promoted metastasis of mesenchymallike breast cancer cells with high expression of cyclin D 1 b.However,the role of cyclin D1b in LPS-induced EMT has not been fully elucidated.In the present study,we described that cyclin D1b augmented EMT induced by LPS in MCF-7 breast cancer cells.Cyclin D1b markedly amplified integrin αvβ3 expression,which was further up-regulated under LPS stimulation.Our results showed ectopic expression of cyclin D1b promoted invasiveness of epithelial-like MCF-7 cells under LPS stimulation.Additionally,LPS-induced metastasis and EMT in MCF-7-D1b cells might depend on αvβ3 expression.Further exploration indicated that cyclin D1b cooperated with HoxD3,a transcription factor promoting αvβ3 expression,to promote LPS-induced EMT.Knockout of HoxD3 repressed LPS-induced EMT and αvβ3 over-expression in MCF-7 cells with high expression of cyclin D1b.Specifically,all these effects were in a cyclin D1a independent manner.Taken all together,LPS up-regulated integrin αvβ3 expression in MCF-7 cells with high expression of cyclin D 1b and induced EMT in breast cancer cells,which highlights that cyclin D1b may act as an endogenous pathway participating in exogenous signal inducing EMT in breast cancer cells.

MP-Rep fusion gene which size is about 1000bp was constructed by recombinant PCR technique.In order to construct fusion gene,Tobacco mosaic virus(TMV) partial movement protein gene(MP) and Cucumber mosaic virus(CMV) partial replicase gene(rep) were ligated.Two copies of MP-Rep fusion gene were ligated with soybean intron in inverted repeat manner,the recombinant fragments were then inserted into binary vector pBIN438 under the control of 35S promoter.Recombinant clone pBIN438-MP-Rep(i/r) which contained two different virus derived genes was constructed.Recombinant clone pBIN438-MP-Rep(i/r) in accord with expected design was certified by restriction endonuclease enzymes digestion and PCR analysis.This approach provides a basis for Broad-spectrum plant virus resistance mediated by RNA Silencing.

OBJECTIVETo study the impact of abdominal obesity on the production of male reproductive endocrine hormones.

METHODSThis study included 342 male patients at the andrology clinic, aged 19 -47 years and higher than 160 cm. We measured their waistlines, hiplines and waist-hip ratio, detected the levels of serum estradiol (E2), testosterone (T), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and free testosterone (FT) by chemiluminescence and radioimmunoassay, and analyzed the correlation of the waist-hip ratio with the levels of reproductive endocrine hormones. Abdominal obesity was defined as the waist-hip ratio > 0.9.

RESULTSIn the 342 male patients, there were 62 cases of abdominal obesity and 280 cases of the normal somatotype (waist-hip ratio < or = 0.9). The waist-hip ratio was negatively correlated with the T level (r = -0.163, P = 0.003) and the T/LH ratio (r = -0.13, P = 0.02). Both the T level and T/LH ratio were significantly reduced in the abdominal obesity patients ([14.51 +/- 4.53] nmol/L and 2.26 +/- 0.36) as compared with the normal somatotype controls ([17.21 +/- 4.23] nmol/L and 4.61 +/- 0.19) (P < 0.05).

CONCLUSIONThe waist-hip ratio has a significant negative correlation with the T level and T/LH ratio, and the serum T level is significantly lower in men with abdominal obesity than in those of the normal somatotype.

Objective · To study the effect of inhibitor of differentiation 1 (ID1) on ocular neovascularization. Methods · The oxygen-induced retinal neovascularization (OIR), laser-induced choroidal neovascularization (CNV) and over-expression of vascular endothelial growth factor (VEGF) (Rho-VEGF) transgenic mice were established. The localization and mRNA level of ID1 in retina of OIR mice and Rho-VEGF transgenic mice were determined by immunofluorescence staining and quantitative real-time PCR. Mice deficient in ID1 (ID1-/-) were used to induce retinal neovascularization in accordance with the above three models, and to compare the changes of ID1 on the number of retinal, subretinal and choroidal neovascularization areas. In order to explore the role ID1 in neovascularization, the numbers and areas of retinal, subretinal and choroidal neovascularization in the mice models with or without ID1 deficiency were compared. Its effect on the related factors, i.e. hypoxia-inducible factor-1α (HIF-1α), VEGF and vascular endothelial growth factor receptor 1/2 (VEGFR1/2) were also observed. Results · Mice deficient in ID1 showed a significant reduction in the area of neovascularization in these three models (P＜0.05). Mice lacking ID1 showed reduced levels of HIF-1α, VEGF and VEGFR 1. Conclusion · ID1 promotes the expression of HIF-1α, VEGF and VEGFR1 in the retina and choroidal neovascularization during hypoxia and oxidative injury.

OBJECTIVETo investigate the protective effect of epigallocatechin gallate (EGCG) on mouse sperm in vivo.

METHODSA total of 64 six-week-old male Kuming mice were randomly divided into eight groups of equal number to be treated with normal saline (negative control), Cyclophosphamide (CP) at 30 mg/kg (positive control), and CP followed by EGCG (experimental) at 20, 40, and 80 mg/kg, respectively, given every other day for 10 days. At 4 and 5 weeks after treatment, the bilateral testes of the mice were harvested for examination of sperm abnormality.

RESULTSEGCG did not increase the rate of CP-induced sperm abnormality in the mice, but reduced it instead with the prolonged time of treatment.

CONCLUSIONEGCG protects mouse sperm in vivo.

OBJECTIVETo study the efficacy and safety of acupuncture therapy for the improvement of sleep quality of outpatients receiving methadone maintenance treatment (MMT).

METHODSUsing randomized double-blinded controlled design, seventy-five MMT outpatients with low sleep quality [score of Pittsburgh sleep quality index (PSQI) > or = 8], were randomly assigned to the acupuncture group (38 cases) and the sham-acupuncture group (37 cases). All patients maintained previous MMT. Acupuncture was applied to Baihui (GV20), Shenmen (bilateral, TF4), Shenting (GV24), Sanyinjiao (bilateral, SP6), and Sishencong (EX-HN1) in the acupuncture group. The same procedures were performed in the sham-acupuncture group, but not to the acupoints (5 mm lateral to the acupoints selected in the acupuncture group) with shallow needling technique. The treatment was performed 5 times each week for 8 successive weeks. The PSQI was assessed before treatment, at the end of the 2nd, 4th, 6th, and 8th week of the treatment. The detection ratio of low sleep quality and the incidence of adverse acupuncture reactions were compared between the two groups at the end of the 8th week.

RESULTSThe overall PSQI score was obviously higher in the acupuncture group than in the sham-acupuncture group with statistical difference (P < 0.01). The detection ratio of low sleep quality at the end of the 8th week was lower in the acupuncture group (60.53%, 23/38 cases) than in the sham-acupuncture group (83.78%, 31/37 cases) with statistical difference (P < 0.05). The rate of adverse acupuncture reaction was 5.26% (2/38 cases) in the acupuncture group and 2.70% (1/37 cases) in the sham-acupuncture group respectively, showing no statistical difference (P > 0.05).

CONCLUSIONAcupuncture therapy could effectively and safely improve the sleep quality of outpatients receiving MMT.
