Objective To investigate the mechanism that bFGF promotes the regeneration of injured optic nerve and induces dedifferentiation of glial cells in it. Methods Fifty-five adult male SD rats were randomly divided into 3 groups as normal control group, injury group and bFGF group. At day 7 post operation, optic nerves from injury group and bFGF group were detected by gene chip and real-time PCR. At day 7, 14 post operation, optic nerves were harvested and detected by HE staining and immunohistochemistry. Results Compared with the injury group, there were 645 genes expression up-regulated and 458 genes down-regulated including genes related neural stem cell or precursor cell neural development, proliferation, apoptosis, chromatin configuration, transcription regulation, signal transduction, neural growth and so on in the bFGF group. There were bigger nuclei, more cells, more immunoreactivity of nestin, extracellular signal-regulated kinase(Erk1/2), glial fibrillary acidic protein(GFAP), and myelin basic protein(MBP) in the distal optic nerves and more immunoreactivity of neurofilament(NF) in the proximal optic nerves in the bFGF group than that in the injury group.Conclusion bFGF could promote the proliferation of neuroglia cells, dedifferentiation of neural glias and improve the microenvironment to favour the regeneration of injured optic nerve.

Objective To investigate the dedifferentiation of neuroglial cells and its induction after optic nerve injury. Methods Adult male SD rats were randomly divided into 4 groups the normal control group,the injury group,the transplantation group and the microcrush and transplantation group.Optic nerves were harvested at days 3,7,14 and 28 after the operation.HE staining was used to count the number of neuroglial cells.Immunohistochemistry,Western blotting and in situ hybridization histochemistry were employed together with computerized image analysis to evaluate the expressions of Nestin,GFAP,MBP,NF,BDNF,Nogo-A and Nogo-A mRNA.Immunofluorescence double staining was used to detect the co-expression of Nestin and GFAP or Nestin and MBP. Results The number of cells only increased at day 7 after the nerve injury, the expressions of Nestin,MBP,Nogo-A and Nogo-A mRNA were up-regulated,the expressions of GFAP,NF and BDNF were down-regulated,and some Nestin-GFAP positive cells and a few of Nestin-MBP positive cells were detected in the injury group.Compared with the injury group,the number of cells was increased sometime after the nerve injury;the expressions of Nestin,GFAP,BDNF and NF were up-regulated,the expressions of MBP,Nogo-A and Nogo-A mRNA were down-regulated,and the number of Nestin-GFAP positive cells increased in the transplantation group and the microcrush and transplantation group.Conclusion After optic nerve injury,some astrocytes undergo dedifferentiation while the macroglial cells display a gene expression pattern that is unfavorable for nerve regeneration.Pre-degenerated peripheral nerves could enhance the dedifferentiation of astrocytes and induce the gene expression pattern of macroglial cells that is favorable for nerve regeneration.

Objective To analyze the influence of hyponatremia on hospitalization days and hospital mortality of hospitalized patients with chronic heart failure. Methods All data were collected from 2465 patients with chronic heart failure in our hospital between January 1980 and August 2007. According to the admission serum sodium, all the patients were divided into two groups: low serum sodium group (Na+<135 mmol/L) and normal serum sodium group (Na+≥135retool/L). Clinical characteristics, therapeutic conditions and the influence of hyponatremia on prognosis were analyzed between the two groups. Results There were 618 patients in low serum sodium group among 2465 cases. Patients with hyponatremia were more likely to have lower systolic blood pressure and lower left ventricular ejection fraction. Lower admission serum sodium was related with higher concentration of serum angiotensin, aldosterone and higher activity of serum renin. Patients in low serum sodium group had significantly longer hospitalization days (Z=-4.026, P<0.01) and higher rate of hospital mortality (χ2=76.935, P<0.01) than patients in normal serum sodium group. Multivariate logistic regression indicated that lower admission serum sodium was an independent risk factor for hospitalization days (b= 0.928, P<0.01) and hospital mortality (OR=0.928, P<0.01). There was a negative correlation between admission serum sodium and hospitalization days (r=-0.132, P<0.01), and the rate of hospital mortality increased by 24.7for each 3 mmol/L decrease in admission serum sodium level. Conclusions Hyponatremia in hospitalized patients with chronic heart failure is relatively common and is associated with poorer heart function, higher activity of neural hormone and more severe prognosis. It is important to prevent hyponatremia for shortening hospitalization days and improving the prognosis of patients with chronic heart failure.

Objective To evaluate clinical application of thyroid fine-needle aspiration biopsy (FNAB) and its diagnostic value.Methods FNAB was performed for 782 cases during 2005-2009 at China-Japan Friendship Hospital,Beijing and their clinical pathological data were retrospectively analyzed.Cytopathological diagnoses by FNAB were classified as unsatisfactory,benign,atypical cellular lesions,follicular neoplasm,suspicious malignancy and definite malignancy.Results of thyroid cytological and histological examinations of 76 patients with subsequent thyroidectomies were compared to those with FNAB to evaluate its diagnostic accuracy.Results Of 782 FNAB specimens,74.4 % (582/782) were classified as benign,2.6 % (20/782) as malignant,5.6 % (44/782) as follicular neoplasm,3.2 % (25/782) as atypical cellular lesion,2.9% (23/782) as suspicious malignancy and 11.3 % (88/782) as unsatisfactory.Among 76 patients with thyroidectomies,65.8 % of them (50/76) were histologically diagnosed as benign lesion,28.9 % (22/76) as definite malignancy and only 5.3 % (4/76) as benign follicular adenoma.Agreement between FNAB cytological diagnoses and histologically confirmed diagnoses for benign lesion and malignancy was 16/16 and 16/17,respectively.Conclusion FNAB is a reliable diagnostic method for evaluation of thyroid nodules.

Objective Sarcandra glabra is a widely-used Chinese medicinal herb,but the wild germplasm resources were decreasing.In order to protect the germplasm resources,the genetic diversity and genetic relationship among the various provenances should be analyzed.Methods ISSR Molecular markers were used to analyze the genetic diversity of S.glabra collected from eight provenances.The genetic diversity,genetic distance,and cluster analysis were performed by Popgen32 software and UPCMA method.Results Ten screened polymorphic primers were used in ISSR-PCR and 111 bands were amplified,among them including 106 polymorphic bands that were about 95.50%.Genetic distance of eight different provenances were ranged from 0.034 7—0.185 0.The genetic diversity of S.glabra mainly came from the interior variation of every provenance,for Gst=0.340 3.Conclusion Provenances of S.glabra can be divided into two groups and based on the relationship of genetic distance and altitude,the provenances can be divieded as follows:correspondingly higher altitude group(800-900 m);correspondingly lower altitude group(250-300 m);middling altitude group(600 m).

[ABSTRACT]AIM:Toobservethelong-termeffectsoftaurine,Danxuetong(Salviamiltiorrhizacombinedwith Xueshuantong ) and breviscapine on contralateral testis with unilateral testicular torsion in prepubertal rats , and to compare their protective effect on testis with ischemia reperfusion injury .METHODS: Four-week-old healthy male SD rats ( n=64) were randomly divided into 8 groups:sham operation group, saline group, single-dose and successive taurine groups, single-dose and successive Danxuetong groups , and single-dose and successive breviscapine groups .The animal model of left testicular torsion reduction (720°for 2 h) was established.After 6 weeks of surgery, the right testes and epididymides from the rats were collected immediately to detect the total antioxidant capacity (T-AOC), the activity of superoxide dis-mutase (SOD), the activity of nitric oxide synthase (NOS) and the content of malondialdehyde (MDA).The sperm de-formity, sperm viability and sperm concentration were measured , and the pathological examination of the testicular tissues was performed.RESULTS:Compared with saline group, the activity of SOD, T-AOC, sperm viability and sperm concen-tration were increased , while MDA content and sperm deformity were decreased in 3 successive groups .SOD activity and sperm viability ( except single-dose breviscapine group ) were increased , but MDA content and sperm deformity were de-creased in 3 single-dose groups .T-AOC activity and sperm concentration were increased in single-dose taurine group .The saline group showed interstitial edema and degeneration of seminiferous tubules , and the rest groups showed a significant improvement in histological morphology .CONCLUSION:The contralateral testis in prepubertal rats was damaged after u-nilateral testicular torsion , and taurine , Danxuetong and breviscapine have long-term protective effect on the tissues under ischemia-reperfusion injury .The protective effect of Danxuetong is better than breviscapine , and taurine is the best of them.The effect of single-dose group is better than the successive application .

OBJECTIVE: To investigate the therapeutic mechanism of letrozole, the third-generation aromatase inhibitor, on endometriotic lesions in a rat model and its effect on the apoptosis of ectopic endometrial cells. METHODS: Endometriosis was induced by autotransplanting pieces of uterus onto the peritoneum in rats. The rats with successful ectopic implants were divided into 2 groups: A letrozole group (n=15) and a control group (n=15). The volume, appearance, and histopathology of ectopic implant were determined before and after the treatment. Expression of P450arom, COX-2, bcl-2, and bax in the ectopic implant was detected by immunohistochemistry and RT-PCR in the 2 groups. RESULTS: The volume of ectopic implant in the letrozole group was significantly reduced compared with the control group (P<0.05). The protein and mRNA levels of P450arom and COX-2 in the ectopic implant were significantly decreased in the letrozole group compared with the control group (P<0.05). There was a positive correlation between the expression of P450arom and the expression of COX-2 (r=0.943, P<0.001; r=0.913, P<0.001). The protein and mRNA expression of bcl-2 was significantly decreased (P<0.05), and the bax protein and mRNA expression was significantly increased (P<0.05) in the ectopic implant with an increased bax/bcl-2 ratio in the letrozole group compared with the control group (P<0.05). CONCLUSION Letrozole can obviously reduce the size of ectopic implant through decreasing P450arom and COX-2 expression, suppressing the secretion of estrogen, inhibiting the proliferation, and inducing the apoptosis of ectopic implants.
