OBJECTIVETo explore the effect of Buyang Huanwu Decoction (BYHWD) and its disassembled recipes on rats' neurogenesis after focal cerebral ischemia and to investigate its underlying molecular mechanisms.

METHODSFocal cerebral ischemia model was induced by occlusion of the right middle cerebral artery for 90 min using the intraluminal filament model. Rats were divided into the sham-operation group, the model group, the BYHWD group, the qi supplementing group, and the blood activating group. Medication was performed by gastrogavage 24 h after ischemia for 14 successive days. 5-bromodeoxyuridine (BrdU) (at 50 mg/kg) was intraperitoneally injected, once per day for 14 successive days. The neurological function was assessed using modified neurological severity score (mNSS) and the corner test at day 1, 7, and 14 after ischemia. BrdU/Nestin, BrdU/NeuN, and BrdU/GFAP positive cells were examined by double immunofluorescence at day 14 after ischemia. The protein expression of brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF) were detected by Western blot at day 14 after ischemia.

RESULTSCompared with the model group, the score of mNSS and the frequency of turning right significantly decreased in the BYHWD group and the qi supplementing group (P < 0.01), the number of BrdU/Nestin in the subventricular zone of the lateral ventricle, and BrdU/ NeuN and BrdU/GFAP positive cells in the peripheral ischemic cortex increased (P < 0.05, P < 0.01), protein expression of BDNF and VEGF increased (P < 0.05, P < 0.01). In the qi supplementing group, there was no statistical difference in BrdU/GFAP. But there was no statistical difference in each index of the blood activating group (P > 0.05). Compared with BYHWD group, the number of BrdU/Nestin, BrdU/ NeuN, and BrdU/GFAP positive cells significantly decreased (P < 0.01), and the protein expression of BDNF and VEGF were significantly reduced in the qi supplementing group and the blood activating group (P < 0.01).

CONCLUSIONSBYHWD could significantly improve neurogenesis and neurological function recovery after focal cerebral ischemia in rats. Its mechanisms might be related to up-regulating protein expression of BDNF and VEGF. Drugs for qi supplementing and drugs for blood activating had synergistic effects.

Objective To explore the associations of depressive symptoms with functional status and frailty in elderly outpatients.Methods A total of 297 geriatric outpatients(aged 65 years and over) from Zhejiang Hospital were recruited in the cross-sectional study from January 2014 to December 2015.We gathered general information,and evaluated depressive symptoms by Geriatric Depression Scale-15 (GDS-15),cognitive function by mini-mental state examination(M MSE),frailty by clinical frailty scale(CFS),activities of daily living (ADL)by Barthel index,instrumental activities of daily living (IADL),balance,POMA and gait by Tinetti-performance oriented mobility assessment (Tinetti-POMA),grip strength and 4m gait speed by 4-meter walk gait speed test.According to the GDS-15 scores,297 geriatric outpatients were divided into a depression symptom group(n=35,GDS-15 ≥6)and a nomdepressive symptom group(n=262,GDS-15＜6).The frailty and functional status were compared between two groups by SPSS 23.0.Results As compared with non-depressive symptoms,the depressive symptoms group had higher clinical frailty scale(CFS),lower body mass index(BMI),lower cognitive function and poorer grip strength and balance(all P＜0.05).There were significantly negative correlations of Geriatric Depression Scale-15 (GDS-15) with ADL,IADL,gait,balance,POMA and grip strength(r=-0.165、-0.154、-0.216、-0.291、-0.305、-0.314,All P＜ 0.05),while there were significantly positive correlations with CFS score,gait speed(r=0.256、0.198,both P＜0.05).The more severe the frailty was,the higher the risk of depressive symptoms was(OR=3.650,95％ CI 1.611-8.271).Conclusions The cognitive and physical functions in the elderly with depression symptoms are poorer as compared with the elderly without depression symptoms.Elderly outpatients with more severe frailty have a higher risk for depressive symptoms.

AIM: To evaluate the therapeutic effect of the PVEP-CD comprehensive therapy \〖a multimedia visual training system uses the individualized PVEP(pattern visual evoked potential)sensitive spatial frequency parameters\〗 in children with amblyopia by comparing the differences in visual acuity and stereo acuity enhancement between the PVEP-CD comprehensive therapy and traditional therapy.

METHODS: A total of 38 children(54 eyes)with amblyopia who were treated in our hospital from April 2018 to January 2019 were randomly divided into two groups. Traditional therapy group(19 cases, 27 eyes; therapeutic methods contain refractive correction, patching/optical or drug suppress and precision eyesight training); PVEP-CD comprehensive therapy group(19 cases, 27 eyes; therapeutic methods contain refractive correction, patching/optical or drug suppress and a multimedia visual training using the individualized P-VEP sensitive spatial frequency parameters). To study the clinic therapeutic effect, the best distance corrected visual acuity(BCVA)and near stereo acuity were measured at the enrollment visit and the final visit after 6mo treatment.

RESULTS: After 6mo treatment, both groups had an apparent BCVA improvement(both therapy effective rate≥85%). PVEP-CD comprehensive therapy group were significantly better than traditional therapy group in BCVA lines improvement \〖3(2, 3)lines\〗, near stereo acuity therapy effective rate(89%)and near stereo acuity level improvement \〖2(1, 4)levels\〗(all P<0.05). In amblyopic children older than 6y, PVEP-CD comprehensive therapy group showed a significantly greater BCVA lines improvement(P=0.018). In mild amblyopia cases, PVEP-CD comprehensive therapy group showed a significantly better clinical efficacy in near stereo acuity(P=0.048)and greater improvement in near stereo acuity level(P=0.029). In moderate amblyopia cases,the BCVA lines improvement(P=0.003)was significantly greater in PVEP-CD comprehensive therapy group.

CONCLUSION:Both PVEP-CD comprehensive and traditional therapy can improve the BCVA in children with amblyopia and have a good clinical efficacy. Furthermore, the PVEP-CD comprehensive therapy could improve the BCVA and near stereo acuity level more obviously and help amblyopic children get a better binocular vision.

Objective:To explore the correlation between hypersomnia and anhedonia in patients with major depressive disorder.Methods:From November 2018 to May 2019, patients hospitalized with major depressive disorder who met the ICD-10 diagnostic criteria were selected.According to the Epworth Sleepiness Scale (ESS), 46 patients were divided into daytime sleepiness group with ESS ≥ 7, and 171 patients were divided into non-sleepiness group with ESS < 7.The Chinese Revised Social Anhedonia Scale (RSAS) and the Chinese Revised Physical Anhedonia Scale (RPAS) were used to evaluate the patients' anhedonia symptoms.Two-way ANOVA and Pearson correlation analysis were used for data processing.Results:(1)There was no interaction between the hypersomnia and gender on the score of physical anhedonia ( F=0.274, P=0.601). The main effect analysis showed that there was significant difference in the influence of gender on physical anhedonia ( F=10.948, P<0.05). (2)There was interaction between the hypersomnia and age on the score of physical anhedonia ( F=4.396, P=0.013). Further simple effect analysis showed that the score of physical anhedonia in 40-49 age(21.54±12.37) was lower than that in 50-64 age(34.13±12.53) in daytime sleepiness group( P<0.05). (3) There was interaction between hypersomnia and sitting and lying on the score of social anhedonia ( F=4.247, P=0.041). Further simple effect analysis showed that the score of social anhedonia in patients with sitting and lying time less than 2 hours (13.71±5.18) was lower than that in patients with sitting and lying time more than 2 hours (19.75±6.39) in daytime sleepiness group( P<0.05). (4)Pearson correlation analysis showed that the total sleepiness score of depression patients was positively correlated with the social anhedonia score ( r=0.206, P<0.01). After adjusting for gender, age and sitting and lying time, the total sleepiness score was still positively correlated with the social anhedonia score( r=0.225, P<0.01). Conclusion:Hypersomnia may be associated with anhedonia in patients with major depressive disorder.

OBJECTIVETo evaluate the current cornea donation awareness of tissue donors in the city of Nanjing, China.

METHODSAltogether 2000 registered tissue donors in the Red Cross Eye Bank of Nanjing by the end of 2010 and 2000 control residents of Nanjing in February to June 2011 were randomly selected to participate in our field questionnaire survey. The questionnaire consisted of questions regarding the understanding of cornea donation, the attitude toward cornea donation, and attitude toward legislation and free donation. The awareness of cornea donation between the registered tissue donors and residents was compared. Related factors of the willing-ness to donate corneas and to become a tissue donor were evaluated with univariate and multiple logistic regression analysis.

RESULTSA total of 1867 (response rate: 93.4%) tissue donors and 1796 (response rate: 89.8%; effective questionnaires: 1697) residents participated in this survey. For the questions about the knowledge of cornea donation, 90.3% tissue donors (residents: 78.9%) knew that donated corneas could be used for transplantations; 71.2% tissue donors (residents: 47.6%) knew that the appearance would not be destroyed after cornea donation; 70.7% tissue donors (residents: 20.0%) knew the formalities to become a cornea donor. For attitude toward cornea donation, 82.2% tissue donors (residents: 45.1%) were willing to donate corneas or eyeballs after death; 84.0% tissue donors (residents: 30.2%) had discussed with their families about donation; 85.1% tissue donors (residents: 24.8%) supported their families' or friends' cornea donation. For attitude toward legislation and free donation, 88.3% tissue donors (residents: 61.3%) approved of legislation to regular cornea donation; 72.2% tissue donors (residents: 38.8%) thought that cornea or organ donation should be gratis. The difference between two groups was significant (P<0.001). However, some tissue donors did not know cornea donation well, some even opposed the legislation of cornea donation and free donation protocol. For the factors influencing the willingness to donate corneas, population was the most relevant factor (P<0.001), since tissue donors were more willing to donate corneas than residents. Other significantly related factor were age, gender, occupation, and education level (P<0.001), while political status or religion were not significant. For the factors related to becoming a tissue donor, older age, male, white-collars (including white-collar, civil servant, teacher, soldier, lawyer, salesman, healthcare provider), higher education level, party members (including the Chinese Communist Party members, democratic party members, and the Communist Youth League members) (P<0.05).

CONCLUSIONSThe registered tissue donors have better understanding and more positive attitude towards cornea donation than control residents do. They approve of the legislation of cornea donation and free donation protocol. It may be more effective to target the population of over 58 years old, male, white-collars, well-educated people, and party members in the promotion of cornea donation.

OBJECTIVETo study the effect of Buyang Huanwu decoction (BYHWD) inducing angiogenesis on the neuroblast migration from the subventricular zone and its mechanisms after focal cerebral ischemia.

METHODThe middle cerebral artery occlusion (MCAO) was performed to mice for 30 minutes to establish the model. The rats were divided into sham group, model group, BYHWD group and endostatin group. BYHWD (20 g x kg(-1), ig) and endostatin (10 μg, sc) were administered 24 h after ischemia once a day for consecutively 14 days. At 14 d after ischemia, the density of micro-vessel and the number of neuroblasts in the ischemia border zone were determined by immunofluorescence staining. The mRNA and protein expression of cell-derived factor-1 (SDF-1) and brain-derived neurotrophic (BDNF) were examined by real-time PCR and Western blot.

RESULTCompared with the model group, BYHWD significantly increased the density of micro-vessel and the number of DCX positive cells in the ischemia border zone (P < 0.01), and significantly increased the SDF-1 and BDNF mRNA and protein expression (P < 0.01). Compared with BYHWD group, endostatin significantly reduced the density of micro-vessel and the number of DCX positive cells in the ischemia border zone (P < 0.01), as well as the SDF-1, BDNF mRNA and protein expression (P < 0.01).

CONCLUSIONBYHWD could promote the neuroblast migration from the subventricular zone via inducing angiogenesis after cerebral ischemia, the mechanism may be correlated with up-regulating the expression of SDF-1 and BDNF.
