Background The effect of chronic stress on cognitive functions has been one of the hot topic in neuroscience. But there has been much controversy over its mechanism. Such single stressor applied in the past could not simulate complicated living circumstances that people confronted with. The aim of this study was to investigate the effects of chronic multiple-stress on learning and memory as well as on the levels of calcium/calmodulin-dependent protein kinase II (CaMKII), calmodulin (CaM) mRNA, and cAMP-response element binding protein (CREB) mRNA in the hippocampus of rats. Methods The rats were divided randomly into stressed and control groups. The stressed group was given chronic multiple-stress for 6 weeks to set up a chronic multiple-stressed model. The rats' performance of spatial learning and memory was tested using Morris Water Maze (MWM) and Y-maze. Meanwhile, the expressions of CaMKII, CaM mRNA and CREB mRNA of rats' hippocampus were detected by immunohistochemistry, Western blot and reverse transcription-polymerase chain reaction (RT-PCR), respectively. In addition, the width of synaptic cleft and the thickness of post-synaptic densities (PSD) were observed in the hippocampal CA3 region of rats by electron microscopy. Results After exposure to chronic multiple-stress for 6 weeks, the ability of learning and memory of the stressed group was higher than that of the control group (P<0.05, P<0.01). The width of synaptic cleft was smaller and the thickness of PSD was larger in the hippocampal CA3 region of the stressed group than in that of the control group (P<0.01). The CaMKII immunostaining of the stressed group was stronger than that of the control group in the stratum radiatum and oriens of the hippocampal CA1 and CA3, especially in the stratum oriens. Quantitative analysis indicated that the expression of CaMKII, CaM mRNA, and CREB mRNA in the hippocampus of the stressed group was higher than that of the control group (P<0.05, P<0.01). Conclusions The capacity of learning and memory can be enhanced after chronic multiple-stress. The increased levels of CaMKII, CaM mRNA, and CREB mRNA may contribute to the enhancing effect of chronic multiple-stress on learning and memory.

OBJECTIVEThe purpose of this registry is to collect data on percutaneous coronary interventions (PCI) performed in various provinces in mainland China in 2005.

METHODSQuestionnaires were send to all hospitals in China and data on PCI, PCI case numbers and type of stents were collected.

This study is to investigate the effect of gamma-hydroxybutyric acid receptor (GHBR) on focal cerebral ischemia-reperfusion injury in rats and its mechanism. NCS-356 (the agonist of GHBR) and NCS-382 (the antagonist of GHBR) were adopted as the tool medicine. The ripe male Sprague-Dawley rats weighing 240 - 280 g were randomly divided into seven groups: sham operation group (sham), ischemia-reperfusion group (Isc/R), NCS-356 160 microg x kg(-1) group (N1), NCS-356 320 microg x kg(-1) group (N2), NCS-356 640 microg x kg(-1) group (N3), NCS-382 640 microg x kg(-1) + NCS-356 640 microg x kg(-1) group (NCS-382 + N3), and nimodipine (Nim) 600 microg x kg(-1) group. The middle cerebral artery occlusion (MCAO) model referring to Longa's method with modifications was adopted. The effect of GHBR on behavioral consequence of MCAO rats was studied after 2 h of ischemia-reperfusion. After 24 h of ischemia-reperfusion, part of animals were used to measure the cerebral infarction volume by TTC staining; ischemic cortex of another part of animals were used to measure the content of intracellular free calcium by flow cytometry, the tNOS, iNOS activity and the content of NO by spectrophotometric method, the content of cGMP by radioimmunoassay. The neurological function score and infarction volume rate in Isc/R group rats increased significantly than that in sham group; The content of intracellular calcium ([Ca2+]) of cortex neuron and cGMP, the activities of tNOS and iNOS, and the content of NO in Isc/R group were higher than that in sham group obviously (P < 0.01); These consequence we mentioned of N1, N2, N3 and Nim group were lower than that of Isc/R. NCS-382 + N3 group could significantly antagonize the above effect of N3. Thus, NCS-356 has protective effects against ischemia-reperfusion brain injury by activating GHBR. The neuroprotective effect of GHBR is related with decreasing the content of [Ca2+]i, NO, cGMP and tNOS, iNOS activity in MCAO rats.

This study was aimed to establish the approach of quantitative PCR (q-PCR) for diagnosis of invasive fungal infections (IFI) in patients with hematologic malignancies. Specimens from 40 patients with hematologic malignancies were chosen for q-PCR and galactomannan (GM) test. The 28S rRNA, a real high consensus sequence of fungi, was selected as target gene to design primer and probe. The DNA of fungal species was extracted from serum specimens. The results showed that q-PCR sensitivity, specificity, positive and negative predictive values were 0.89, 0.85, 0.89, 0.85 respectively; GM test sensitivity, specificity, positive and negative predictive values were 0.83, 0.80, 0.88, 0.73 respectively; as combined q-PCR with GM test, these values were 0.94, 0.85, 0.89, 0.92 respectively. It is concluded that the q-PCR assay can be used for early diagnosis for IFI in patients with hematologic malignancies, q-PCR combined with GM test can enhance the diagnosis sensitivity for IFI.

Objective To determine the urinary iodine level of people in Yunyang and Bishan County of Chongqing and explore into its influencing factors. Methods Using multistage cluster stratified simple random sample method, Yunyang and Bishan County were chosen as research spots, then thirty children aged 8-10 in each 3 primary school of the 2 counties were selected using stratified randomization sampling method to inspected their urine and household salt for iodine and the iodine content in drinking water. Results Five hundred and seventy-one urine samples were inspected and the urinary iodine median was 261.47 μg/L. 5.78% (33/571) and 37.48%(214/571) of samples had an urinary iodine median less than 100 μg/L and more than 300 μg/L. The urinary iodine median of Yunyang County was higher than that of Bishan (H = 7.42, P < 0.01). The iodine salt coverage rate, the qualified rate and edible qualified iodine salt rate respectively were 99.64%(554/556), 94.22% (522/554) and 93.88% (522/556) in 556 samples of family table salt. Eighty-seven samples of drinking water were inspected, resulting an averaged iodine content of 8.81 and 2.97 μg/L, respectively in the 2 counties. Conclusions The 2 counties are all the area of iodine deficiency. The urinary iodine level, although meeting the demand of eliminating iodine deficiency diseases, is a little bit higher given that iodized salt of present doage has been taken for a long time. The content of iodized salt should be adjusted accordingly.

Authors raised that staging based strategies and practice of integrative medicine (IM) by combining syndrome typing and disease identification, and choosing suitable measures in accordance with different persons and seasonal conditions after more than ten years' clinical practice and researches. Radical operation as prior (as evil eliminating) and strengthening vital qi in perioerative period are best strategy for promoting rapid rehabilitation of early stage prostate cancer patients. Strengthening body resistance to eliminate evil was used in treating advanced prostate cancer patients. For example, a comprehensive treatment program for hormone-dependent patients was combined with endocrinotherapy and Chinese herbs for synergisic efficacy-enhancing actions. In this way, these patients' quality of life (QOL) were improved and time to castration resistant prostate cancer (CRPC) was delayed, even some patients were clinically cured. There are lack of effective medicines and methods for CRPC patients. Greatly tonifying original qi is mainly used for improving their clinical symptoms and prolonging survivals. Practice has proved staging based strategies and practice of IM has favorable advantages in treating prostate cancer, especially showing prospect in prolonging survival and postponing progression of advanced prostate cancer patients. Besides, it also could provide beneficial considerations and inspiration for combination of syndrome typing and disease identification.
