Inmanysensory systems, receptive fields (RFs) measured by spike responses undergo progressive refinement during development. It has been proposed that elimination of excitatory synaptic inputs underlies such functional refinement. However, despite many extracellular recording and anatomical studies, direct in vivo intracellular evidence has remained limited. In this study, by cell-attached recordings in the developing optic tectum of zebrafish, we found that during a short period after the initial formation of retinotectal synapses, spike visual RFs of tectal neurons underwent a two-stage developmental modulation: from an initial expansion to a later refinement. Whole-cell voltage-clamp recordings revealed that the underlying excitatory synaptic RF exhibited a similar developmental progression, with its spatial extent first increased and then reduced, and its spatial tuning profile gradually sharpened. The inhibitory RF was initially larger than the excitatory RF but became matched with the excitatory RF at later stages. Simulation with the integrate-and-fire neuron model suggested that the developmental changes of excitatory RFs primarily accounted for the initial enlargement and later refinement of spike RFs, whereas inhibitory inputs generally reduced the size of the spike RF without affecting its developmental progression. In addition, spike RF of individual retinal ganglion cells did not significantly change in size during the same period, and the spatial extent and tuning profile of the tectal excitatory RF barely changed after intratectal excitatory connections were silenced. Together, our results demonstrate that the functional refinement of tectal visual RFs results primarily from a selective elimination of feedforward retinotectal inputs. © 2011 the authors.

Neuregulin-1 (NRG-1) is a member of the epidermal growth factor family. Our previous study showed that NRG-1 protected neurons from apoptosis following focal cerebral ischemia by the inhibition of caspase-3 and TNF-a expression. However, the molecular signaling mechanisms for this action of NRG-1 following cerebral ischemia are not fully understood. Presently, activation of the PI3K/Akt pathway has been implicated as a major contributor to neuronal survival after an ischemic insult. In the present study, we investigated whether NRG-1 modulates the activation of Akt and its downstream targets Bad and Bcl-2 expression after transient focal cerebral ischemia by intraluminal blockade of the middle cerebral artery. Western blot was employed to analyze the change of phosphorylated Akt (p-Akt) expression; reverse transcription and polymerization chain reaction (RT-PCR) were used to measure changes of Bcl-2 mRNA. The level of phosphorylation of Bad (p-Bad) was determined using an enzyme-linked immunosorbent assay (ELISA). Our results showed that recombinant human NRG-1(3.0 ng kg-1) significantly increased the expression of p-Akt protein, Bcl-2 mRNA, and the level of p-Bad, respectively, whereas administration of LY294002, a specific inhibitor of PI3K, significantly decreased the expression of p-Akt, p-Bad, and Bcl-2 induced by NRG-1 after a 60 min ischemic insult, followed by 24 h of reperfusion. These results indicate that NRG-1 may be involved in regulating the expression of Bcl-2 and p-Bad through the PI3K/Akt pathway after transient focal cerebral ischemia.

Parkinson's disease (PD) is a surprisingly heterogeneous disorder with symptoms including resting tremor, bradykinesia and rigidity. PD has been associated with abnormal task related brain activation in sensory and motor regions as well as reward related network. Although corticostriatal skeletomotor circuit dysfunction is implicated in the neurobiology of Parkinson's disease, the functional connectivity within this circuit at the resting state is still unclear for PD. Here we utilized resting state functional magnetic resonance imaging to measure the functional connectivity of striatum and motor cortex in 19 patients with PD and 20 healthy controls. We found that the putamen, but not the caudate, exhibited enhanced connectivity with supplementary motor area (SMA), using either the putamen or the SMA as the "seed region". Enhanced SMA-amygdala functional connectivity was also found in the PD group, compared with normal controls. Our findings highlight the key role of hyper-connected putamen-SMC circuit in the pathophysiology of PD. © 2013 Yu et al.

To assess the clearance role and safety of Chinese herbal enema therapy (CHET) in clearing enterogenic uremic toxins in chronic renal failure (CRF) patients, thus providing evidence for further optimizing the comprehensive treatment. Using nonrandomized concurrent control trial, 96 CRF inpatients of Department of Nephropathy, Guangdong Provincial Hospital of Traditional Chinese Medicine, from March 2010 to December 2010 were assigned to the treatment group and the control group according to their willingness. All patients were treated with basic treatment referring to clinical plans in the non-dialysis phase, while those in the treatment group were additionally treated with CHET, once daily, 2 weeks as one therapeutic course. The symptoms, serum enterogenic uremic toxin levels [including indoxyl sulfate (IS), blood urea nitrogen (BUN), and uric acid (UA)], and serum creatinine (SCr) were observed in the two groups between and after treatment. The adverse reactions were also monitored during the treatment period. The clinical efficacy and safety were also assessed. Totally 84 patients completed this clinical observation, 48 in the treatment group and 36 in the control group. The levels of SCr, BUN, and IS were obviously lower in the treatment group after treatment, showing statistical difference when compared with before treatment (P<0.01). There was no statistical difference in each index in the control group between before and after treatment (P>0.05). The post-treatment the IS level was lower in the treatment group than in the control group with statistical difference (P<0.05). Symptoms like fatigue, soreness of waist and knees, constipation and edema were partially relieved in both groups (P<0.05, P<0.01). The ratios of anorexia and nausea in patients of the treatment group was lowered after treatment (P<0.05). Besides, patients in the treatment group could defecate for more than once daily during the enema treatment period, dominated as rotten and soft feces. No severe adverse event occurred during the treatment period. CHET combined basic treatment could lower the serum levels of enterogenic uremic toxins (IS and BUN) of CRF patients in a short period.

To observe the effect of integrative medical therapy on the prognosis of patients suffering from yin syndrome type acute ischemic stroke (YS-AIS). A multi-center, prospective, random and parallel controlled clinical trial was carried on 606 patients of YS-AIS. Excepting the 15 patients being excluded and dropped out in the trial period, all patients were assigned to the treatment group (274 patients) treated with integrated medical protocol (i. e. Chinese medical therapy plus conventional Western medical treatment), and the control group (263 patients) treated with conventional Western medical treatment plus placebo. Patients' quality of life (QOL) and their disability level were assessed by scoring based on SS-QOL and modified Rankin scale (mRS) respectively at the terminal of the 21-day treatment (T1) and at the ends of 60-day (T2) and 90-day (T3) following-ups. Patients' disability level, showed by mRS scores, was not significantly different between the two groups at T1 and T2 (P > 0.05), but with significant difference at T3 (P < 0.05). The recovery in the treatment group were more significant. Although the SS-QOL scores showed no statistical significant difference between groups (P > 0.05), improvement of QOL could be seen in the treatment group and the difference between groups was more significant as the time went by. Integrative medical therapy could reduce the severe disability rate in patients after YS-AIS, and showed an improving trend on patients' QOL at T3.

In this article, the concept of complementary and alternative medicine (CAM) was reviewed, and the functions and status of Chinese medicine in malignant tumor therapy as a CAM were summarized. The major usage of Chinese medicine as a CAM in treatment of malignant tumor are as follows: (1) Chinese medicine alone can be used as an alternative therapy for advanced patients who cannot benefit from chemotherapy or radiotherapy; (2) Chinese medicine can be used together with chemotherapy or radiotherapy as a complementary therapy to alleviate signs and symptoms, reduce toxicities and increase effect; (3) Chinese medicine can be used as an alternative therapy for elderly or patients with poor performance status (PS); (4) it can also combine with new technology (e.g., extracorporeal high frequency thermotherapy, radioactive seed implantation, and radiofrequency ablation) as a complementary treatment; (5) Chinese medicine can work with molecular target therapeutic drugs to increase efficacy and sensitivity, reduce toxicities, improve quality of life and prolong survival; (6) Chinese medicine can act as a maintenance therapy after surgery, chemotherapy and radiotherapy; (7) Chinese medicine can also be taken as a preventive measure in high-risk patients with pre-cancerous diseases or "tumor-free" status. Finally, the author concluded the prescription pattern of Chinese medicine in treatment of malignant tumor, and presented several clinical effective cases treated with Chinese medicine.

To investigate the contents changes of potential biomarkers of patients infected with influenza A (H1N1) virus of different Chinese medicine (CM) syndrome types. Eighty-two patients with influenza A (H1N1) virus were differentiated as three syndrome types, i. e., wind-heat invading weifen syndrome (51 cases), heat-toxicity attacking Fei syndrome (22 cases), and superficies tightened by wind cold syndrome (9 cases) according to Chinese medicine syndrome typing. According to patients' willingness and clinical conditions, they were treated by three therapeutic schedules, i. e., herbal therapy, symptomatic treatment, and antiviral therapy. The changes of potential biomarkers contents were detected in the serum of patients of various syndrome types before and after treatment. Results There was no statistical difference in the potential biomarkers contents correlated to symptoms of fever, inflammation and cough, such as PGG2, 20-COOH-LTB4, homocystein, and so on in the serum of patients of various syndrome types before treatment (P > 0.05). There was statistical difference in the potential biomarkers such as 20-OH-LTE4, LTA4, and linolenic acid, etc. between superficies tightened by wind cold syndrome and wind-heat invading weifen syndrome (P < 0.05, P < 0.01). There was statistical difference in the potential biomarkers such as PGF1alpha, prostanoic acid, and etc. between superficies tightened by wind cold syndrome and heat-toxicity attacking Fei syndrome (P < 0.05, P < 0.01). Statistical difference existed in other indices other than dUTP; 5,10-methylene-THF and PGF1alpha in wind-heat invading weifen syndrome and superficies tightened by wind cold syndrome; prostanoic acid, homocysteine, and glucose in superficies tightened by wind cold syndrome when compared with before treatment in the same group (P < 0.05, P < 0.01). The changing tendency of potential biomarkers among different syndrome types was identical. Of them, the change of 6-keto-PGF1alpha content was the most obviously of all indices. There was difference in the contents of potential biomarkers of patients infected with influenza A (H1N1) virus of different syndrome types, and our study provided experimental data support for the objectiveness of CM syndrome differentiation from the perspective of metabolic substances.

To further articulate the conceptual framework of sub-health by way of literature review. Published papers and relevant literature about sub-health were collected, the representative publishing about theoretical exploration and practical surveys were focused for analyzing and assessing the category of sub-health, investigative objects, assessing tools, conceptual framework, diagnostic criteria and its operability, foundation support, etc. Sub-health conditions were categorized into three kinds in most documents, namely, the somatic, the mental and the social adaptative sub-health, and the relevant symptoms were classified into three levels. However, contents regarding the homogeneous issues, such as meaning and definition of sub-health, its diagnostic criteria and operability, in different documents were discrepant. Discrepancy exists between the theoretical and practical studies of sub-health. And detailed description is needed to articulate the problems respectively on specific and non-specific sub-health. The perspicuity of conceptual framework is the basis of sub-health researches. The authors recommended that to form the framework the four-level hierarchic structure should be adopted; in developing the assessing tool for sub-health diagnosis, besides the basic assessment on concrete conditions, the differential evaluation on the belonging of overall manifestations, subjective complain or objective symptom, should also be paid attention to.

To study the clinical efficacy and mechanisms of Youdujing (YDJ) preparation in treating the cervical high-risk human papilloma virus (HR-HPV) infection. Totally HR-HPV infection 70 patients were assigned to the treatment group and the control group using random single blind method, 35 cases in each group. YDJ external lotion and YDJ cream were applied to patients in the treatment group, while normal saline was applied for those in the control group. HR-HPV DNA detection was performed by the end of the 1st menstruation after 3 menstrual cycles. The cervical biopsy and cervical smear were performed using vaginoscope before and after treatment. The mRNA expression of human telomerase reverse transcriptase (hTERT) was detected from fresh tissues of the cervical lesion. The total effective rate was 96.6% in the treatment group, higher than that of the control group (70.00%, P<0.01). Before treatment there was no statistical difference in the pathological results of the cervix and the mRNA expression of hTERT between the two groups (P>0.05). The mRNA expression of hTERT decreased in the two groups after treatment, showing statistical difference (P<0.01). Better effects on the pathological results of the cervix and the mRNA expression of hTERT were obtained in the treatment group after treatment (P<0.05). YDJ played a role in clearing HR-HPV infection and reversing the cervical precancerous changes possibly through down-regulating the mRNA expression of hTERT and lowering the telomerase activation.

To observe the clinical effect of Chinese medicine for nourishing yin and clearing heat therapy (CM therapy) in treating nasopharyngeal carcinoma (NPC) patients with yin deficiency-induced inner heat syndrome, and suffered from acute radiation oral mucositis. Sixty patients with NPC fitting to the inclusion criteria and undergoing initial dose radiotherapy were assigned to two groups. The 31 patients in the treatment group received CM therapy, and the 29 in the control group were treated with standard Western medical therapy. The condition of oral mucosa and epidermal growth factor (EGF) content in saliva of patients during the therapeutic period were observed, meanwhile the quality of life (QOL) of patients was estimated with the quality of life questionnaire-core 30 (QLQ-C30) issued by European Organization for Research and Treatment of Cancer (EORTC). Acute radiation oral mucositis occurred in all patients, but the severity in the treatment group was milder than that in the control group (P < 0.01). Salivary EGF content decreased along with the increasing radiation dosage, it decreased significantly when 40 Gy radiated and down to the minimum when 70 Gy radiated, but the decrement in the treatment group was less than that in the control group (P < 0.01). Comparison of QOL by QLQ-C30 scale showed that after radiotherapy the global health status in the treatment group was superior to the control group (P < 0.01). Chinese medicine for nourishing yin and clearing heat therapy could actually postpone the occurrence of acute radiation oral mucositis, lessen the adverse reaction of radiotherapy and improve patient's QOL, show a favorable effect in prevention and treatment, and has definite application value for clinical spreading.
