Androgen deprivation therapy can effectively suppress the progression of prostate cancer, but accumulating evidence for the relationship of testosterone with prostate cancer challenges the conventional wisdom. High levels of testosterone are not risk factors for prostate cancer, nor promote its development. On the contrary, a low testosterone level indicates a worse pathological stage. So far there has been no strong evidence to prove the role of testosterone in the occurrence and progression of prostate cancer. Therefore, the relationship between testosterone and prostate cancer is quite complicated and deserves further investigation.

Objective To investigate the correlation between the plasma unconjugated bilirubin(UCB)and electrical activity of brain in term neonates with hyperbilirubinemia,and explore the parameters that possess the prognostic value and deduce a series of discriminant for prognostic judgment.Methods Thirty-two neonates with hyperbilirubinemia and 31 neonates without hyperbilirubinema(control group)were studied with standard EEG,and they were assessed for their neurological development in 3 and 6 months.A statistical method of Bayes Discriminant analysis was adopted to set up an equation with values of parameters of EEG,clinic datum and consequence.Stepdic and Dis-grim processes were used to pick out the parameters which had great significance for predicting the outcome of nervous system development.A series of discriminant was deduced for prognostic judgment and then cross validation was performed to assess the accuracy of the discriminant.Results 1.The standard EEG and brain electrical activity map records indicated that the hyperbilirubinemia group had longer maximum duration of interburst interval(IBI),longer mean duration of IBI,lower amplitude under all conditions,more anterior dysrhythmia(AD)in wake,and higher incidence of sleep-wake cycle disturbance.2.The plasma concentration of UCB was linear correlated with AD in wake.3.Gestational age,birth weight,plasma concentration of UCB,burst duration of IBI in trace alternate,amplitude in all sleep state,AD in wake,brief burst not in quiet sleep and sleep-wake cycle disturbance might play important roles in predicting the outcome of neonates with hyperbilirubinemia.Conclusions Cerebral electrical activity is an effective tool for predicting neurologic outcome of neonates with hyperbi-lirubinemia.Cerebral electrical activity and clinic data will provide a new method for accurately predicting neurological development and prognosis.

OBJECTIVETo evaluate therapeutic effect of the needle-knife closed solution combined with minor adjusting of spine for treatment of neck-shoulder syndrome.

METHODSFrom April 2010 to August 2011,120 patients with neck-shoulder syndrome were treated with the needle-knife closed solution combined with minor adjusting of spine, and included 45 males and 75 females and aged from 40 to 68 years old. The disease course was from 3 days to 10 years. After the operation, all patients taken the medicine of activating blood circulation herbs. At the 3rd, 7th, 10th day after operation, spinal rotation massage was performed on these patients. After the healing of the needle points, traditional Chinese medicine herb fumigation was applied on the needle points, and the patients were directed to do the cervical spine exercise. Therapeutic effect of the patients was evaluated by the neck disability index (NDI).

RESULTSAll patients were followed up after 3 weeks' treatment. The pain of neck-shoulder was relieved, and the range of motion was improved,the NDI score lowered from 49.30 +/- 1.35 before treatment to 10.15 +/- 1.18 at 3 weeks after treatment (t = 2.116, P < 0.05).

CONCLUSIONThe needle-knife closed solution combined with minor adjusting of spine for the treatment of neck-shoulder syndrome can relieve the pain in the neck-shoulder and improved the motion of the neck. The key for the effect is accurate location before operation, sufficient adhesion solution during the operation and spinal minor adjusting after operation.

OBJECTIVESTo investigate the changes of nuclear factor (NF-)κBp65 and inflammatory chemotactic factors including monocyte chemoattractant protein 1 (MCP-1/CCL-2), macrophage inflammatory protein 1α (MIP-1α/CCL-3), glial fibrillary acidic protein (GFAP) in brains of the patients with Alzheimer's disease (AD) and reveal the correlation of these factors.

METHODSTen patients with AD and 8 age-matched control subjects were selected in the study. Immunohistochemistry was performed to determine the protein expression of NF-κBp65, MCP-1, MIP-1α and GFAP. Double-immunohistochemistry was used to detect the expression of GFAP and β-amyloid peptide 1-42 (Aβ(1-42)) in the hippocampus, temporal and frontal cortices.

RESULTSAs compared to age-matched controls (the numbers of the positively stained neuronal cells: 0.31 ± 0.20, 0.25 ± 0.20 and 0.25 ± 0.20, respectively), the immunoreactivities of NF-κBp65 in the hippocampus and the temporal and frontal cortices (numbers of the positively stained cells: 3.6 ± 1.5, 2.2 ± 1.2 and 2.2 ± 1.2, respectively) were significantly increased in AD brains. The levels of MCP-1 and MIP-1α in the hippocampus, and the temporal and frontal cortices (numbers of the positively stained neuronal cells: 8.0 ± 1.3, 8.8 ± 1.0, 9.3 ± 1.4, respectively;and 8.1 ± 1.5, 12.5 ± 1.1, 6.4 ± 1.1, respectively) with AD were significantly higher than those of controls (the numbers of the positive neuronal cells: 4.5 ± 0.9, 4.5 ± 0.6, 4.0 ± 1.8, respectively; and 5.0 ± 1.9, 6.3 ± 2.2, 3.8 ± 1.5, respectively). An increased number of glial cells stained with GFAP were observed to extensively distribute around the senile plaques in AD brains. There were significant correlations between NF-κBp65 and these inflammatory chemotactic factors in AD brains.

CONCLUSIONCorrelative expressions of NF and inflammatory chemotactic factors were found in the brains of AD patients, through a mechanism that may involve the inflammatory response induced by Aβ in the processing of AD.

Objective To localize the sinoatrial node (SAN) of the newborn rabbits in vivo and cut it for purifying cultivation and study the morophologic characters of primary cultured pacemaker cells of SAN under light microscope and transmissional electron microscope. Methods Hearts of the newborn rabbits were embedded in paraffin for HE-staining and observed the location, form of SAN under optical microscope; SAN cells isolated from neonatal rabbits cultured and purified with the method of differential attachment and BrdU-treatment.Results SAN localized in the anterior wall of the superior vena cava and the posterior-lateral atrial wall.There was about 0.32 mm between its lowest point and sulcus terminalis. Three distinctly different types of cells were observed among the cultured cells of SAN: spindle, araneiform and polygon. The spindle cells covered the greatest proportion of the cultured cells of SAN (59.6%?7.3%). The frequency of spontaneous contraction of spindle cells was the highest among the constrcting cells (145 ?9)time/min. The results of ultrastructure observation showed that myofibrils and other organelles in spindle cells were poorly organized and significantly decreased in number compared with araneiform cells. There was no significant difference between araneiform cells isolated from SAN and from atrial muscle.Conclusion Among the cultured cells from neonatal rabbits SAN, the spindle cells are the pacemaker cells of SAN.

To reveal the effect of rotation cropping and bacterial manure on the growth of Chrysanthemum morifolium and screen the beneficial endophytic, the diversity of endophytic and dominant genera of different treatment groups were analyzed. Four different treatments were continuous cropping, rotation, self-made organic fertilizer and commercially available fertilizer, respectively. Endophytic bacterial diversity and dominant genera in different organs were examined using Terminal Restriction Fragment Length Polymorphism (T-RFLP). The results showed that enzyme Hae III was more appropriate than enzyme Hinfl because the number of TRFs digested by enzyme Hae III was more than that of enzyme Hinfl. In comparison of diversity, the endophytic bacterial communities' diversity index in group of cropping rotation and fertilizer was higher than that of continuous cropping which indicated that the addition of exogenous microorganism in soil could increase the diversity of plant endophyte. 18 dominant species were selected, including 3 kinds of Firmicutes, 4 kinds of Actinomycetes and 11 kinds of Proteobacteria. The results of dominant species comparison showed that the number of dominant species in continuous cropping of Ch. morifolium was significantly less than that of the rotation group. Some dominant bacteria in rotation group and fertilizer group such as Arthrobacter, Streptomyces, Streptomyces, Flavobacterium and Mycobacterium were not found in the continuous cropping of Ch. mortfolium group. Dominant species of fertilizer treatment group was similar with the rotation group, and the continuous cropping group's dominant species was more abundant. It indicates that these bacteria may be able to mitigate hindrance in continuous cropping, especially the Flavobacterium which can decompose the pathogenic fungi is worthy of further attention. Compared with leaves, there are more dominant species in roots and stems. The diversity of edophytic bacterial communities in continuous cropping of Ch. morifolium stays below than that in the rotation of Ch. morifolium, and fertilizer treatment can increase the diversity of continuous cropping so that it could mitigate hindrance in continuous cropping.
