ObjectiveTo investigate the protective effect of the extract of Liuwei Dihuangwan （LW） on mitochondrial damage in the Alzheimer's disease （AD） model of Caenorhabditis elegans （C. elegans）. MethodC. elegans transfected with human β-amyloid protein （Aβ） 1-42 gene was used as an AD model. The rats were divided into blank group， model group， metformin group （50 mmol·L-1）， and low， medium， and high dose （1.04， 2.08， 4.16 g·kg-1） LW groups. Behavioral methods were used to observe the sensitivity of 5-hydroxytryptamine （5-HT） in nematodes. Western blot was used to detect the expression of Aβ in nematodes. Total ATP content in nematodes was detected by the adenine nucleoside triphosphate （ATP） kit， and mitochondrial membrane potential was detected by the JC-1 method. In addition， the mRNA expression of Aβ expression gene （Amy-1）， superoxide dismutase-1 （SOD-1）， mitochondrial transcription factor A homologous gene-5 （HMG-5）， mitochondrial power-associated protein 1 （DRP1）， and mitochondrial mitoprotein 1 （FIS1） was detected by real-time fluorescence quantitative polymerase chain reaction （RT-PCR）. ResultThe extract of LW could reduce the hypersensitivity of the AD model of nematodes to exogenous 5-HT （P<0.05） and delay the AD-like pathological characteristics of hypersensitivity to exogenous 5-HT caused by toxicity from overexpression of Aβ in neurons of the AD model of nematodes. Compared with the blank group， in the model group， the mRNA expression of Aβ protein and Amy-1 increased （P<0.01）， and the mRNA expression of SOD-1 and HMG-5 decreased （P<0.01）. The mRNA expression of DRP1 and FIS1 increased （P<0.01）， and the level of mitochondrial membrane potential decreased （P<0.05）. The content of ATP decreased （P<0.01）. Compared with the model group， in the positive medicine group and medium and high dose LW groups， the mRNA expression of Aβ protein and Amy-1 decreased （P<0.05，P<0.01）， and the mRNA expression of SOD-1 and HMG-5 increased （P<0.01）. The mRNA expression of DRP1 decreased （P<0.05，P<0.01）， and that of FIS1 decreased （P<0.01）. The level of mitochondrial membrane potential increased （P<0.01）， and the content of ATP increased （P<0.05，P<0.01）. ConclusionThe extract of LW may enhance the antioxidant ability of mitochondria， protect mitochondrial DNA， reduce the fragmentation of mitochondrial division， repair the damaged mitochondria， adjust the mitochondrial membrane potential， restore the level of neuronal ATP， and reduce the neuronal damage caused by Aβ deposition.

Effects of luminous environments on visual performance of people with different vision / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To study the effects of the specific simulated luminous environment on the visual performance of people with different vision, so as to provide an experimental basis for revising pilots' vision standards. METHODS: A controlled randomized trial was conducted. Twenty-four volunteers were recruited and divided into four groups(1.0/1.0, 0.8/0.8, 0.6/0.6 and 0.4/0.4, decimal vision)according to right/left eye visual acuity, with six subjects in each group. Each subject was tested for static distant vision, kinetic visual acuity, color vision, depth perception error and visual search time under the simulated luminous environments of sunlight, twilight, and on-cloud, respectively, to compare changes in the impact of distinctive luminous surroundings on the visual performance indicators of human beings with different vision.RESULTS: There were main effect differences in static distant vision, kinetic visual acuity, color error, depth perception error and visual search time under different light environments(all P&#x003C;0.01). The binocular static distant visual acuity, abilities of color discrimination, depth perception and visual search in simulated sunlight environment were higher than those in simulated twilight and on-cloud environments. In the 0.4/0.4 vision group, kinetic vision in simulated twilight and on-cloud environments were significantly lower than that in simulated sunlight environment(P&#x003C;0.01). There were main effect differences in binocular static distant vision, kinetic visual acuity, depth perception error and visual search time among subjects with different vision(all P&#x003C;0.05). Compared with 1.0/1.0 vision group, those with 0.6/0.6 and 0.4/0.4 vision had significant decrease in kinetic visual acuity, depth perception ability and visual search ability(all P&#x003C;0.05). CONCLUSION: Different luminous environments have a great impact on the visual performance of people with low vision, which poses a potential threat to flight safety.

Thoughts on fund compensation of adverse events following immunization in China / 上海预防医学

After the promulgation and implementation of the Vaccine Administration Law of the People’s Republic of China， the compensation of suspected adverse reactions in China is to be reformed and innovated. There have been attempts at compensation through government finance and insurance， but there has been no precedent for a fund of vaccine-related compensation in China， which means that this could be a new method of solving disputes of compensation for vaccine-related incidences and enhancing public confidence in vaccination. It is suggested that under the current system， we can select a province as a pilot to explore the fund compensation mechanism. The fund comes from special financial allocation， special taxation of vaccine enterprises， fund investment income， charitable donation and other channels. Through a special fund management organization， the independent identification and compensation process can be realized， so as to shorten the current compensation procedure， improve the amount of compensation， ultimately protect the interests of all parties， and promote the steady development of vaccination.

Effects of Electroacupuncture on Metabolic Changes in Motor Cortex and Striatum of 6-Hydroxydopamine-Induced Parkinsonian Rats / 中国结合医学杂志

OBJECTIVE@#To explore the possible underlying mechanism by investigating the effect of electroacupuncture (EA) treatment on the primary motor cortex and striatum in a unilateral 6-hydroxydopamine (6-OHDA) induced rat Parkinson's disease (PD) model.@*METHODS@#Male Sprague-Dawley rats were randomly divided into sham group (n=16), model group (n=14), and EA group (n=14). EA stimulation at Dazhui (GV 14) and Baihui (GV20) was applied to PD rats in the EA group for 4 weeks. Behavioral tests were conducted to evaluate the effectiveness of EA treatment. Metabolites were detected by 7.0 T proton nuclear magnetic resonance.@*RESULTS@#Following 4 weeks of EA treatment in PD model rats, the abnormal behavioral impairment induced by 6-OHDA was alleviated. In monitoring changes in metabolic activity, ratios of myoinositol/creatine (Cr) and N-acetyl aspartate (NAA)/Cr in the primary motor cortex were significantly lower at the injected side than the non-injected side in PD rats (P=0.024 and 0.020). The ratios of glutamate + glutamine (Glx)/Cr and NAA/Cr in the striatum were higher and lower, respectively, at the injected side than the non-injected side (P=0.046 and 0.008). EA treatment restored the balance of metabolic activity in the primary motor cortex and striatum. In addition, the taurine/Cr ratio and Glx/Cr ratio were elevated in the striatum of PD model rats compared to sham-lesioned rats (P=0.026 and 0.000). EA treatment alleviated the excessive glutamatergic transmission by down-regulating the striatal Glx/Cr ratio (P=0.001). The Glx/Cr ratio was negatively correlated with floor plane spontaneous locomotion in PD rats (P=0.027 and P=0.0007).@*CONCLUSIONS@#EA treatment is able to normalize the metabolic balance in the primary motor cortex and striatum of PD rats, which may contribute to its therapeutic effect on motor deficits. The striatal Glx/Cr ratio may serve as a potential indicator of PD and a therapeutic target of EA treatment.

The effectiveness of diabetes medication therapy adherence clinic to improve glycaemic control among patients with type 2 diabetes mellitus: a randomised controlled trial

@#Introduction: In Malaysia, Diabetes Medication Therapy Adherence Clinic (DMTAC) in hospital settings significantly improved patients' glycaemic control and cardiovascular risk. Until now no randomised controlled trial of DMTAC has been done in a primary care setting where the access to subspecialist services (endocrinologists, expensive medication, etc.) is limited. The objective of this research is to compare the glycaemic control among diabetes mellitus (DM) patients between those received additional DMTAC service and those received normal clinic service in primary care settings. Materials and Method: This was a parallel, randomised controlled study. The selected participants were patients aged 18 to 70 years with type 2 DM on diabetic medication who were being treated in Kota Samarahan Health Clinic with HbA1c above 8% and who never attended any education of DM prior to the study. The control group received normal clinic visits with consultations by a medical officer. The intervention group received four or more DMTAC visits in addition to normal clinic visits. The primary outcomes were HbA1c while the secondary outcomes were the occurrence of severe hypoglycaemia, weight gain and medication compliance of patients. The subjects were randomised by numbered envelope opened chronologically by the investigator during the initial assessment. All health care professionals (nurse, lab staff and medical officer) except DMTAC pharmacist managing the subjects were blinded as there were no markings on the patients notes indicating that they were in this study. The demographic data was collected during screening while health data including glycated haemoglobin (HbA1c) levels were collected at baseline, sixth month and one year. Results: In all, 100 patients were randomised into control and intervention groups (n=50 per arm). The change of HbA1c in the intervention group (mean=-1.58) was significantly more than the control group (mean=-0.48) at 12 months with a mean difference of -1.10% (p=0.005, Cohen's d=0.627). Both study groups had similar significant changes of subjects from non-compliance to compliance (control group, n=11 vs. intervention group, n=10). The changes of BMI after 12 months between control group (0.24 kg/m2 ) and intervention group (0.24 kg/m2 ) was not significant (p=0.910). There were no episodes of severe hypoglycaemia detected in both groups. Conclusion: The addition of DMTAC service in primary care can improve glycaemic control among patients. The study was registered in the National Medical Research Register (Malaysia): NMRR-13-1449-18955 FUNDING: This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors. All blood test was done in our setting.

Objective:To investigate that the effect of ethanol extracts from Sophorae Tonkinensis Radix et Rhizoma on the expression of transforming growth factor-β1 (TGF-β1)and Smad3 in the hypertrophic scars of rabbit ears and elucidate its mechanism to improve hypertrophic scars. Method:The model of hypertrophic ear scar model was established by damaging the inner skin of ears in New Zealand white rabbits.The 49 rabbits were randomly divided into control group, model group, low, medium and high-dose ethanol extracts groups from Sophorae Tonkinensis Radix et Rhizoma (0.4，1.0，2.0 g·kg-1), asiaticoside ointment group(5 mg·kg-1) and compound heparin sodium allantoin gel group(20 mg·kg-1), 7 rabbits per group. Except control group, the different drug about 0.5 mL had been applied the hypertrophic scar of rabbit ears once a day. After 42 days, the tissues of hypertrophic scar were obtained. Hematoxylin-eosin（HE）staining was used to observe the pathological changes of rabbit ear scar tissue and determine the scar hyperplasia index. The expression of TGF-β1 and Smad3 in scar tissue of rabbit ears were detected by immunohistochemistry, Western blot and reverse transcription PCR（RT-PCR）. Result:Compared with control group, the pathological changes of the ear scars in the model group showed obvious hyperplasia and higher hyperplasia index (P<0.01). Meanwhile, the expressions of TGF-β1 and Smad3 in scar tissue of rabbit ears were significantly increased (P<0.01). Compared with model group, the pathological structures of the ear scar tissue were significantly improved and the hyperplasia index of ear scar tissue was clearly reduced in medium and high-dose groups of ethanol extracts from Sophorae Tonkinensis Radix et Rhizoma(P<0.05，P<0.01). The protein and mRNA expression of TGF-β1 and Smad3 in scar tissue were also decreased in different group of ethanol extracts from Sophorae Tonkinensis Radix et Rhizoma compared with the model group (P<0.05，P<0.01). Conclusions:Ethanol extracts from Sophorae Tonkinensis Radix et Rhizoma may play a curative role in inhibiting hypertrophic scars by reducing the expression of TGF-β1 and Smad3 in scar tissue and inhibiting the TGF-β1/Smads signal transduction pathway. These provides the experimental basis for the clinical application of Sophorae Tonkinensis Radix et Rhizoma in the treatment of hypertrophic scars.

Association between psoriasis and STAT3 / 中华皮肤科杂志

Psoriasis is a chronic inflammatory skin disease.Its pathogenesis remains unclear,and is currently considered to be co-mediated by heredity,environment and immunity.Signal transducer and activator of transcription 3 (STAT3) is an important transcription factor,which is associated with cancer and autoimmune diseases.STAT3 plays a crucial role in the occurrence of psoriasis by participating in the differentiation of T helper 17 cells,hyperproliferation and abnormal differentiation of keratinocytes,interaction with inflammatory cells,hyperplasia of dermal vessels and other important pathological processes.In recent studies,therapies targeting STAT3 and its upstream Janus kinases (JAK) have shown good efficacy and safety in the management of psoriasis.This review summarizes the association between psoriasis and STAT3,so as to provide evidence for the feasibility of the treatment of psoriasis with targeted inhibition of STAT3.

Effect of inhibitor of differentiation 1 deficiency on ocular neovascularization / 上海交通大学学报（医学版）

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.

Whole-Brain Mapping of Direct Inputs to and Axonal Projections from GABAergic Neurons in the Parafacial Zone / 神经科学通报·英文版

The GABAergic neurons in the parafacial zone (PZ) play an important role in sleep-wake regulation and have been identified as part of a sleep-promoting center in the brainstem, but the long-range connections mediating this function remain poorly characterized. Here, we performed whole-brain mapping of both the inputs and outputs of the GABAergic neurons in the PZ of the mouse brain. We used the modified rabies virus EnvA-ΔG-DsRed combined with a Cre/loxP gene-expression strategy to map the direct monosynaptic inputs to the GABAergic neurons in the PZ, and found that they receive inputs mainly from the hypothalamic area, zona incerta, and parasubthalamic nucleus in the hypothalamus; the substantia nigra, pars reticulata and deep mesencephalic nucleus in the midbrain; and the intermediate reticular nucleus and medial vestibular nucleus (parvocellular part) in the pons and medulla. We also mapped the axonal projections of the PZ GABAergic neurons with adeno-associated virus, and defined the reciprocal connections of the PZ GABAergic neurons with their input and output nuclei. The newly-found inputs and outputs of the PZ were also listed compared with the literature. This cell-type-specific neuronal whole-brain mapping of the PZ GABAergic neurons may reveal the circuits underlying various functions such as sleep-wake regulation.

A Critical Time-Window for the Selective Induction of Hippocampal Memory Consolidation by a Brief Episode of Slow-Wave Sleep / 神经科学通报·英文版

Although extensively studied, the exact role of sleep in learning and memory is still not very clear. Sleep deprivation has been most frequently used to explore the effects of sleep on learning and memory, but the results from such studies are inevitably complicated by concurrent stress and distress. Furthermore, it is not clear whether there is a strict time-window between sleep and memory consolidation. In the present study we were able to induce time-locked slow-wave sleep (SWS) in mice by optogenetically stimulating GABAergic neurons in the parafacial zone (PZ), providing a direct approach to analyze the influences of SWS on learning and memory with precise time-windows. We found that SWS induced by light for 30 min immediately or 15 min after the training phase of the object-in-place task significantly prolonged the memory from 30 min to 6 h. However, induction of SWS 30 min after the training phase did not improve memory, suggesting a critical time-window between the induction of a brief episode of SWS and learning for memory consolidation. Application of a gentle touch to the mice during light stimulation to prevent SWS induction also failed to improve memory, indicating the specific role of SWS, but not the activation of PZ GABAergic neurons itself, in memory consolidation. Similar influences of light-induced SWS on memory consolidation also occurred for Y-maze spatial memory and contextual fear memory, but not for cued fear memory. SWS induction immediately before the test phase had no effect on memory performance, indicating that SWS does not affect memory retrieval. Thus, by induction of a brief-episode SWS we have revealed a critical time window for the consolidation of hippocampus-dependent memory.
