Deep transcranial magnetic stimulation for treatment-resistant depression: A systematic review and meta-analysis of randomized controlled studies. Asian J Psychiatr 2024; 96:104032. [PMID: 38574492 DOI: 10.1016/j.ajp.2024.104032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 03/22/2024] [Accepted: 03/24/2024] [Indexed: 04/06/2024]
Abstract
The efficacy and safety of deep transcranial magnetic stimulation (dTMS) in treating treatment-resistant depression (TRD) are unknown. Up to June 21, 2023, we conducted a systematic search for RCTs, and then extracted and synthesized data using random effects models. Five RCTs involving 507 patients with TRD (243 in the active dTMS group and 264 in the control group) were included in the present study. The active dTMS group showed significantly higher study-defined response rate (45.3% versus 24.2%, n = 507, risk ratio [RR] = 1.87, 95% confidence interval [CI]: 1.21-2.91, I2 = 53%; P = 0.005) and study-defined remission rate (38.3% versus 14.4%, n = 507, RR = 2.37, 95%CI: 1.30-4.32, I2 = 58%; P = 0.005) and superiority in improving depressive symptoms (n = 507, standardized mean difference = -0.65, 95%CI: -1.11--0.18, I2 = 82%; P = 0.006) than the control group. In terms of cognitive functions, no significant differences were observed between the two groups. The two groups also showed similar rates of other adverse events and all-cause discontinuations (P > 0.05). dTMS is an effective and safe treatment strategy for the management of patients with TRD.

Transcranial alternating current stimulation for schizophrenia: a systematic review of randomized controlled studies. Front Psychiatry 2024; 14:1308437. [PMID: 38274423 PMCID: PMC10808327 DOI: 10.3389/fpsyt.2023.1308437] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 12/27/2023] [Indexed: 01/27/2024] Open
Abstract
Background In randomized clinical trials (RCTs) investigating the application of transcranial alternating current stimulation (tACS) in schizophrenia, inconsistent results have been reported. The purpose of this exploratory systematic review of RCTs was to evaluate tACS as an adjunct treatment for patients with schizophrenia based on its therapeutic effects, tolerability, and safety. Methods Our analysis included RCTs that evaluated adjunctive tACS' effectiveness, tolerability, and safety in schizophrenia patients. Three independent authors extracted data and synthesized it using RevMan 5.3 software. Results Three RCTs involving 76 patients with schizophrenia were encompassed in the analysis, with 40 participants receiving active tACS and 36 receiving sham tACS. Our study revealed a significant superiority of active tACS over sham tACS in improving total psychopathology (standardized mean difference [SMD] = -0.61, 95% confidence interval [CI]: -1.12, -0.10; I2 = 16%, p = 0.02) and negative psychopathology (SMD = -0.65, 95% CI: -1.11, -0.18; I2 = 0%, p = 0.007) in schizophrenia. The two groups, however, showed no significant differences in positive psychopathology, general psychopathology, or auditory hallucinations (all p > 0.05). Two RCTs examined the neurocognitive effects of tACS, yielding varied findings. Both groups demonstrated similar rates of discontinuation due to any reason and adverse events (all p > 0.05). Conclusion Adjunctive tACS is promising as a viable approach for mitigating total and negative psychopathology in individuals diagnosed with schizophrenia. However, to gain a more comprehensive understanding of tACS's therapeutic effects in schizophrenia, it is imperative to conduct extensive, meticulously planned, and well-documented RCTs.

[A study of the clinical curative effect of nucleos(t)ide analogues treated to pegylated interferon-α add-on therapy in patients with chronic hepatitis B]. ZHONGHUA GAN ZANG BING ZA ZHI = ZHONGHUA GANZANGBING ZAZHI = CHINESE JOURNAL OF HEPATOLOGY 2023; 31:1297-1305.

Abstract
Objective: To investigate the hepatitis B surface antigen (HBsAg) clearance condition and its predictive factors after treatment with nucleos(t)ide analogues to pegylated interferon-α add-on therapy in patients with chronic hepatitis B. Methods: Patients with chronic hepatitis B who visited the First Affiliated Hospital of Zhengzhou University from 2018~2019 were prospectively enrolled. HBsAg≤ 1500 IU/mL, hepatitis B e antigen-negative, HBV DNA undetectable, received antiviral treatment with nucleos(t)ide analogues for at least one year, and pegylated interferon-α add-on therapy for 48 weeks were included. The primary endpoint of study was to determine the proportion of HBsAg clearance at 72 weeks. Concurrently, the predictive factors for HBsAg clearance were analyzed. Quantitative and qualitative data were analyzed using a t-test or non-parametric test and a Fisher's exact test. Results: A total of 38 cases were included in this study, of which 13 cases obtained HBsAg clearance at 48 weeks of therapy and another six cases obtained HBsAg clearance throughout the extended treatment period of 72 weeks, accounting for 50.00% of all enrolled patients. There was a significant difference in HBsAg dynamics between the HBsAg clearance group and the non-clearance group (P < 0.05). Univariate logistic regression analysis showed that patients' age, baseline, 12-and 24-week HBsAg levels, and early HBsAg reduction were predictive factors for HBsAg clearance at 72 weeks of treatment. Multivariate logistic regression analysis showed that age (OR = 1.311; P = 0.016; 95% confidence interval: 1.051~1.635) and HBsAg levels at 24 weeks of treatment (OR = 4.481; P = 0.004; 95% confidence interval: 1.634~12.290) were independent predictors for HBsAg clearance. Conclusion: Hepatitis B e antigen-negative, nucleos(t)ide analogue treated, HBsAg ≤ 1500 IU/mL, and HBV DNA undetectable, peg-IFNα add-on treatment for 48 weeks could promote HBsAg clearance in patients with chronic hepatitis B. Six of the sixteen cases (37.50%) who did not obtain HBsAg clearance at week 48 did so with the course of therapy extended to week 72. Hence, the optimal individualized treatment strategy should be customized according to the predictors rather than the fixed 48-week course. Age (≤ 38), baseline HBsAg level (≤2.86 log(10)IU/ml), HBsAg level at 24 weeks (≤ 0.92 log(10)IU/ml), and 12-week HBsAg decrease from baseline (≥ 0.67 log(10)IU/ml) indicate that patients are highly likely to obtain HBsAg clearance at the 72 weeks of combination therapy, in which the combined indicator based on HBsAg level ≤0.92 log(10)IU/ml at 24 weeks will identify 85.0% to 100.0% of patients with HBsAg clearance.

Dietary non-phytate phosphorus requirements for optimal productive and reproductive performance, and egg and tibial quality in egg-type duck breeders. Animal 2023; 17:101022. [PMID: 37976778 DOI: 10.1016/j.animal.2023.101022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 10/14/2023] [Accepted: 10/17/2023] [Indexed: 11/19/2023] Open
Abstract
Optimal dietary non-phytate phosphorus (NPP) is essential in poultry to maximise productive and reproductive performance, along with indices of egg and bone quality. This study aimed to establish the NPP requirements of egg-type duck breeders aged from 54 to 80 weeks on the following traits: egg production, egg incubation, egg quality, tibial characteristics, reproductive organ, plasma indices, and the expression of genes related to phosphorus absorption. Longyan duck breeders aged 54 weeks (n = 300) were randomly allotted to five treatments, each containing six replicates of 10 individually caged birds. Birds were fed corn-soybean meal-based diets containing 0.18, 0.25, 0.32, 0.38, and 0.45% NPP/kg for 27 weeks. The tested dietary NPP levels did not affect egg production or egg quality indices. The hatchling weight of ducklings increased (quadratic, P < 0.01) as dietary NPP level increased, and the highest value occurred with 0.25% NPP. The number of large yellow follicles (LYF), and the relative weights of LYF and ovary showed linear and quadratic responses to dietary NPP levels; the lowest number and relative weight of LYF occurred with 0.38% NPP, and the lowest ovarian weight was obtained with 0.25% NPP. There were no differences in tibial length, breaking strength, and mineral density in response to dietary NPP levels. In contrast, tibial content of Ca increased (linear, P < 0.01) with dietary NPP levels increasing from 0.18 to 0.45%, and the tibial content of P increased at 0.32% NPP and the higher dietary NPP levels. Plasma concentration of P showed a quadratic (P < 0.05) response to the dietary NPP levels, where the highest value was seen at 0.38% NPP. In conclusion, dietary NPP levels from 0.18 to 0.45% had no effects on egg production, and egg and tibial quality of duck breeders. The duck breeders fed a diet with 0.25% NPP showed the highest hatchling weight of their offspring, while those fed 0.38% NPP had the lowest number and relative weight of LYF. These results indicated that the diet with 0.25% NPP can be used in egg-type duck breeders to improve the hatchling weight of their offspring, without adverse effects on their productivity. The regression model indicated that the maximal hatchling weight of ducklings was obtained from duck breeders fed the diet with 0.30% NPP.

Bilateral theta burst stimulation for patients with acute unipolar or bipolar depressive episodes: A systematic review of randomized controlled studies. J Affect Disord 2023; 340:575-582. [PMID: 37579881 DOI: 10.1016/j.jad.2023.08.065] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 08/03/2023] [Accepted: 08/11/2023] [Indexed: 08/16/2023]
Abstract
OBJECTIVE This meta-analysis of randomized controlled trials (RCTs) evaluated the overall efficacy and safety of bilateral theta-burst stimulation (TBS) as an intervention for patients with mood disorders. METHODS A systematic search (up to December 7, 2022) of RCTs was conducted to address the study aims. A random-effects meta-analysis was performed by including study-defined responses and remission as primary outcomes. RESULTS Analyses included six RCTs comprising 285 participants with major depressive disorder (MDD) (n = 233) or a depressive episode in the course of bipolar disorder (BD) (n = 52) who had undergone active bilateral TBS (n = 142) versus sham stimulation (n = 143). Active bilateral TBS outperformed sham stimulation with respect to study-defined improvements (55.1 % versus 20.3 %, 4 RCTs, n = 152, 95%CI: 1.63 to 4.39, P < 0.0001; I2 = 0 %) and remission rates (37.2 % versus 14.3 %, 2 RCTs, n = 85, 95%CI: 1.13 to 5.95, P = 0.02; I2 = 0 %) in MDD patients but not those with bipolar or unipolar mixed depression. Superiority of active bilateral TBS over sham stimulation was confirmed for improvements in depressive symptoms at post-bilateral TBS assessments and 8-week follow-ups in patients with either MDD or mixed depression (all P < 0.05). Discontinuation rates due to any reason and adverse events (i.e., headache, dizziness) were similar between TBS and sham stimulation groups with MDD or mixed depression (all P > 0.05). CONCLUSION Bilateral TBS targeting the dorsolateral prefrontal cortex (DLPFC) appears to be a well-tolerated form of repetitive transcranial magnetic stimulation (rTMS) that has substantial antidepressant effects, particularly in patients with MDD. Effects of bilateral TBS on bipolar and unipolar mixed depression should be further investigated.

Abstract
Helvella is a widespread, frequently encountered fungal group appearing in forests, but the species diversity and molecular phylogeny of Helvella in China remains incompletely understood. In this work, we performed comprehensive phylogenetic analyses using multilocus sequence data. Six datasets were employed, including a five-locus concatenated dataset (ITS, nrLSU, tef1-α, rpb2, hsp), a two-locus concatenated dataset (ITS, nrLSU), and four single-locus datasets (ITS) that were divided based on the four different phylogenetic clades of Helvella recognized in this study. A total of I 946 sequences were used, of which 713 were newly generated, including 170 sequences of ITS, 174 sequences of nrLSU, 131 sequences of tef1-α, 107 sequences of rpb2 and 131 sequences of hsp. The phylogeny based on the five-locus concatenated dataset revealed that Helvellas. str. is monophyletic and four phylogenetic clades are clearly recognized, i.e., Acetabulum clade, Crispa clade, Elastica clade, and Lacunosa clade. A total of 24 lineages or subclades were recognized, II of which were new, the remaining 13 corresponding with previous studies. Chinese Helvella species are distributed in 22 lineages across four clades. Phylogenetic analyses based on the two-locus concatenated dataset and four single-locus datasets confirmed the presence of at least 93 phylogenetic species in China. Among them, 58 are identified as known species, including a species with a newly designated lectotype and epitype, 18 are newly described in this paper, and the remaining 17 taxa are putatively new to science but remain unnamed due to the paucity or absence of ascomatal materials. In addition, the Helvella species previously recorded in China are discussed. A list of 76 confirmed species, including newly proposed species, is provided. The occurrence of H. crispa and H. elastica are not confirmed although both are commonly recorded in China. Citation: Mao N, Xu YY, Zhang YX, Zhou H, Huang XB, Hou CL, Fan L (2023).

Abstract
PURPOSE/OBJECTIVE(S) The HARVEST trial (NCT03829553) is a phase III, multicenter, randomized clinical trial to explore efficacy and safety of hypofractionated irradiation (HFI) involving regional nodal irradiation (RNI, including internal mammary nodes, IMN) in N+ breast cancer patients treated with mastectomy or breast conserving surgery (BCS). Current study aims to analyze the dosimetric quality assurance so as to evaluate the compliance to the trial protocol. MATERIALS/METHODS Eligible patients were randomly assigned (1:1) to receive conventional fractionated irradiation (CFI: 50 Gy/25Fx) or HFI (40.05 Gy/15Fx), which is delivered to ipsilateral chest wall or whole breast (CW/WB) with tumor bed boost (HFI: 10.68 Gy/4Fx; CFI: 10 Gy/5Fx) and comprehensive RNI (supra/infraclavicular nodes and IMN in each patient, lower axilla if indicated) by using IMRT technique. The plan quality was evaluated based on dose distribution, dose volume histogram (DVH) and field parameters. The target coverage, including planning target volume of CW/WB (PTV1) and tumor bed (PTV2) and doses of the organs at risk (OARs) were evaluated. The LQ model was used to convert doses of OARs in HFI group using α/β = 3 Gy (EQD23) for comparison. RESULTS Between Feb 21, 2019 and Feb 14, 2022, 801 patients were enrolled at 8 centers with 401 and 400 in CFI and HFI group, respectively. There were 182 patients received BCS and 387 patients were with more than three positive lymph nodes. In the CFI group, the D90 and V45 of PTV1 reached the prescribed dose in 70.6% and 96.0% of the patients, respectively. In the HFI group, the D90 and V36 of PTV1 reached the prescribed dose in 87.8% and 95.5% of the patients, respectively. When the tumor bed was irradiated, the D90 of PTV2 reached the prescribed dose in 95.6% in the CFI group and 100% in the HFI group, respectively. The mean D90 of PTV1 and PTV2 were 50.09±0.65 Gy and 60.63±0.91 Gy in CFI group while 40.11±0.56 Gy and 50.79±2.03 Gy in HFI group. For OARs constraints, protocol compliance was all above 95% (heart: 95.3%; ipsilateral lung: 95.5%; contralateral lung: 97.1%; humeral head: 98.2% and spinal cord: 100%) with no significant difference between CFI and HFI groups. For patients with left-sided breast cancer, the Dmean of the heart was 5.10±1.75 Gy vs. 4.59±1.86 Gy (EQD23) in CFI and HFI groups (p = 0.51), respectively. No significant differences in Dmean of the heart (1.45±0.71 Gy vs. 1.33±0.77 Gy (EQD23), p = 0.40) was found either between two groups in right-sided patients. The differences were significant in the Dmean of the ipsilateral lung (13.37±1.99 Gy vs. 11.17±3.50 Gy (EQD23), p<0.01), contralateral lung (0.88±0.73 Gy vs. 0.74±0.61 Gy (EQD23), p<0.01) and the ipsilateral humeral head (15.27±7.62 Gy vs. 13.05±6.19 Gy (EQD23), p<0.01) and the Dmax of spinal cord (21.40±8.82 Gy vs. 19.47±7.99 Gy (EQD23), p = 0.05) between CFI and HFI groups. CONCLUSION A high degree of compliance with protocol dose constraints was found for treatment plans in the HARVEST trial and doses to the most of OARs decreased in HFI group.

Abstract
PURPOSE/OBJECTIVE(S) Recurrence risk score model was established to distinguish the recurrent risk of patients with pathologic nodal negative (ypN0) after neoadjuvant chemotherapy (NACT) and mastectomy and determine the impact of postmastectomy radiotherapy (PMRT). MATERIALS/METHODS This multicenter retrospective study reviewed 766 patients who underwent mastectomy and NACT with ypN0 from 2000 to 2014. Recurrent risk score model was assigned proportionally to the relative contribution of independent prognostic factors in the multivariate Cox model of disease-free survival (DFS). Decision tree analysis was conducted to determine two optimal cutoff points for stratification. RESULTS The median follow-up time was 74 months. The 5-year locoregional control (LRC), DFS, and overall survival (OS) rates for the entire group were 96.5%, 89.1% and 95.3%, respectively. 353 (46.1%) patients received PMRT and 413 (53.9%) patients did not. Patients with PMRT have more high-risk factors, including age <40 years, clinical stage III, grade III, or ER and PR negative. Chest wall and regional nodal region were irradiated in 307 (87.0%) and chest wall only in 46 (13.0%). The median radiation dose was 50 Gy (range: 36-60 Gy) in 25 fractions (range: 15-30 fractions). There were no significant differences between the PMRT and No-PMRT groups in the LRC, DFS and OS rates. Recurrent risk score model consisted of five factors and used a range of zero to eleven scoring points: age <40 years and clinical N1 stage for one point; clinical N2, NACT ≥4 cycles, lymphovascular invasion and ypT1-2 for two points; ypT3-4 for four points. 456 (59.5%) patients scoring zero to four points, 188 (24.5%) scoring five points and 122 (15.9%) scoring six to eleven points were assigned to the low-, intermediate-, and high-risk group. LRC, DFS and OS rates in three risk groups were significantly distinct from each other (5yr-LRC: 98.6% vs. 95.5% vs. 89.8%, p < .001; 5yr-DFS: 94.4% vs. 87.4% vs. 71.5%, p < .001; 5yr-OS: 97.6% vs. 93.2% vs. 90.0%, p < .001). PMRT had no impact on the LRC, DFS and OS rates in either low-, intermediate-, or high-risk group. CONCLUSION The recurrence risk score model can effectively distinguish patients with different recurrent risk stratification. PMRT in patients with ypN0 after NAC and mastectomy cannot improve LRC, DFS or OS. Table 1. Survival outcomes and comparison between PMRT and No-PMRT arms in different groups.

Abstract
Objective This meta-analysis of randomized clinical trials (RCTs) was conducted to explore the therapeutic effects, tolerability and safety of repetitive transcranial magnetic stimulation (rTMS) as an adjunct treatment in adolescents with first-episode major depressive disorder (FE-MDD). Methods RCTs examining the efficacy, tolerability and safety of adjunctive rTMS for adolescents with FE-MDD were included. Data were extracted by three independent authors and synthesized using RevMan 5.3 software with a random effects model. Results A total of six RCTs involving 562 adolescents with FE-MDD were included. Adjunctive rTMS was superior in improving depressive symptoms over the control group [standardized mean difference (SMD) = -1.50, 95% confidence interval (CI): -2.16, -0.84; I2 = 89%, p < 0.00001] in adolescents with FE-MDD. A sensitivity analysis and two subgroup analyses also confirmed the significant findings. Adolescents with FE-MDD treated with rTMS had significantly greater response [risk ratio (RR) = 1.35, 95% CI: 1.04, 1.76; I2 = 56%, p = 0.03] and remission (RR = 1.35, 95% CI: 1.03, 1.77; I2 = 0%, p = 0.03) over the control group. All-cause discontinuations were similar between the two groups (RR = 0.79, 95% CI: 0.32, 1.93; I2 = 0%, p = 0.60). No significant differences were found regarding adverse events, including headache, loss of appetite, dizziness and nausea (p = 0.14-0.82). Four out of six RCTs (66.7%), showed that adjunctive rTMS was more efficacious over the control group in improving neurocognitive function (all p < 0.05). Conclusion Adjunctive rTMS appears to be a beneficial strategy in improving depressive symptoms and neurocognitive function in adolescents with FE-MDD. Higher quality RCTs with larger sample sizes and longer follow-up periods are warranted in the future.

Efficacy and safety of intermittent theta burst stimulation versus high-frequency repetitive transcranial magnetic stimulation for patients with treatment-resistant depression: a systematic review. Front Psychiatry 2023; 14:1244289. [PMID: 37583841 PMCID: PMC10423820 DOI: 10.3389/fpsyt.2023.1244289] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Accepted: 07/17/2023] [Indexed: 08/17/2023] Open
Abstract
Objective Intermittent theta-burst stimulation (iTBS), which is a form of repetitive transcranial magnetic stimulation (rTMS), can produce 600 pulses to the left dorsolateral prefrontal cortex (DLPFC) in a stimulation time of just over 3 min. The objective of this systematic review was to compare the safety and efficacy of iTBS and high-frequency (≥ 5 Hz) rTMS (HF-rTMS) for patients with treatment-resistant depression (TRD). Methods Randomized controlled trials (RCTs) comparing the efficacy and safety of iTBS and HF-rTMS were identified by searching English and Chinese databases. The primary outcomes were study-defined response and remission. Results Two RCTs (n = 474) investigating the efficacy and safety of adjunctive iTBS (n = 239) versus HF-rTMS (n = 235) for adult patients with TRD met the inclusion criteria. Among the two included studies (Jadad score = 5), all were classified as high quality. No group differences were found regarding the overall rates of response (iTBS group: 48.0% versus HF-rTMS group: 45.5%) and remission (iTBS group: 30.0% versus HF-rTMS group: 25.2%; all Ps > 0.05). The rates of discontinuation and adverse events such as headache were similar between the two groups (all Ps > 0.05). Conclusion The antidepressant effects and safety of iTBS and HF-rTMS appeared to be similar for patients with TRD, although additional RCTs with rigorous methodology are needed.

Accelerated intermittent theta burst stimulation for major depressive disorder or bipolar depression: A systematic review and meta-analysis. Asian J Psychiatr 2023; 85:103618. [PMID: 37201381 DOI: 10.1016/j.ajp.2023.103618] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 05/02/2023] [Accepted: 05/05/2023] [Indexed: 05/20/2023]
Abstract
We aimed to systematically evaluate the clinical efficacy and safety of accelerated intermittent theta burst stimulation (aiTBS) for patients with major depressive disorder (MDD) or bipolar depression (BD). A random-effects model was adopted to analyze the primary and secondary outcomes using the Review Manager, Version 5.3 software. This meta-analysis (MA) identified five double-blind randomized controlled trials (RCTs) comprising 239 MDD or BD patients with a major depressive episode. Active aiTBS overperformed sham stimulation in the study-defined response. This MA found preliminary evidence that active aiTBS resulted in a greater response in treating major depressive episodes in MDD or BD patients than sham stimulation.

[PMID: 36993925 PMCID: PMC10040676 DOI: 10.3389/fpsyt.2023.1145301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Accepted: 02/20/2023] [Indexed: 03/14/2023] Open
Abstract
BackgroundElectroconvulsive therapy (ECT) is a safe and effective therapy for individuals suffering from major psychiatric disorders, but attitudes towards ECT among patients and caregivers have not been well studied. This study was conducted to elucidate patient and caregiver knowledge and attitudes concerning ECT in South China.MethodsThe sample comprised 92 patients diagnosed with major psychiatric disorders and their caregivers (n = 92). Participants completed questionnaire measures of knowledge and attitudes related to ECT.ResultsInformation before ECT was inadequately provided to both caregivers and patients (55.4% versus 37.0%, p < 0.05). Caregivers reported receiving more adequate information about the therapeutic effects (50.0% versus 44.6%), side effects (67.4% versus 41.3%), and risks (55.4% versus 20.7%) of ECT when compared to patients (all p < 0.05). However, less than half of patients and caregivers believed that ECT was effective (43.5% versus 46.7%, p > 0.05), while more than half of them believed that ECT was beneficial (53.3% versus 71.7%, p < 0.05), and approximately half of them believed that ECT was safe (50.0% versus 51.1%, p > 0.05). A total of 32.6% of patients and 55.4% of caregivers (p < 0.05) reported that ECT was used only for critically ill patients. A total of 62.0% of patients experienced side effects, with memory impairment being the most commonly reported.ConclusionClinicians should develop a systematic health education program before ECT treatment and ensure that patients and caregivers have an accurate understanding of ECT, particularly the treatment process, its therapeutic effects and potential side effects prior to administering this treatment.

Adjunctive transcranial alternating current stimulation for patients with major depressive disorder: A systematic review and meta-analysis. Front Psychiatry 2023; 14:1154354. [PMID: 37032914 PMCID: PMC10073427 DOI: 10.3389/fpsyt.2023.1154354] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Accepted: 03/06/2023] [Indexed: 04/11/2023] Open
Abstract
Objective We performed a meta-analysis of randomized, double-blind, controlled trials (RCTs) to systematically investigate the therapeutic effects and tolerability of transcranial alternating current stimulation (tACS) for the treatment of patients with major depressive disorder (MDD). Methods Electronic search of PubMed, PsycINFO, EMBASE, Chinese National Knowledge Infrastructure, Wanfang database, and the Cochrane Library up to 1 April 2022. Double-blind RCTs examining the efficacy and safety of tACS for patients with MDD were included. The primary outcome was the improvement of depressive symptoms following a course of tACS treatment. Data were analyzed using Review Manager Version 5.3 (Cochrane IMS, Oxford, UK). Study quality was assessed using the Cochrane risk of bias and Jadad scale. Publication bias was assessed using a funnel plot and the Egger test. Results We identified 883 articles, of which 4 RCTs with 5 active treatment arms covering 224 participants with MDD on active tACS (n = 117) and sham tACS (n = 107) were eligible for inclusion. Meta-analysis of depressive symptoms at post-tACS found an advantage of active tACS over sham tACS (n = 212, standard mean difference (SMD) = -1.14, 95% confidence interval (CI): -2.23, -0.06; I 2 = 90%, P = 0.04). The significant superiority of active tACS over sham tACS in improving depressive symptoms remained in a sensitivity analysis. Active tACS was significantly superior to sham tACS regarding depressive symptoms at the 4 week follow-up (SMD = -1.07, 95% CI: -2.05, -0.08; I 2 = 88%, P = 0.03) and study-defined remission [risk ratio (RR) = 2.07, 95% CI: 1.36, 3.14, I 2 = 9%, P = 0.0006]. The discontinuation rate due to any reason was similar between the two groups (P > 0.05). All included studies were rated as high quality (Jadad score ≥ 3), with funnel plots of primary outcome not suggestive of publication bias. Conclusion tACS appeared to be modestly effective and safe for improving depressive symptoms in patients with MDD, although further studies are warranted.

Abstract
OBJECTIVE We performed this systemic review to investigate the therapeutic potential and safety of adjunctive accelerated repetitive transcranial magnetic stimulation (aTMS) for older patients with depression. METHODS We included published randomized clinical trials (RCTs) and observational studies targeting adjunctive aTMS for older patients with depression. RESULTS Two open-label self-controlled studies (n = 29) fulfilled the criteria for inclusion. The included studies reported significant improvements in depressive symptoms from baseline to post-aTMS (all Ps < 0.05). One study reported a dropout rate of 10.5% (2/19). Mild headache was the most common adverse reaction. CONCLUSION The currently available evidence from two open-label self-controlled studies indicates that adjunctive aTMS is a safe and effective therapy for older patients with depression.

Abstract
Oncomelania hupensis is the only intermediate host of Schistosoma japonicum, and O. hupensis control is an important measure for schistosomiasis control. With the progress of national schistosomiasis control program, the prevalence of schistosomiasis is low in China; however, there are still multiple challenges for O. hupensis breeding and schistosomiasis transmission risk. Considering the target of the national schistosomiasis elimination program and environmental protection in the new era, the introduction of precision identification, precision interventions and precision assessment into O. hupensis control may facilitate the progress towards elimination of schistosomiasis in China.

Effects of dietary inclusion of cassava starch-extraction-residue meal on egg production, egg quality, oxidative status, and yolk fatty acid profile in laying ducks. Poult Sci 2022; 101:102015. [PMID: 35905547 PMCID: PMC9334324 DOI: 10.1016/j.psj.2022.102015] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 06/11/2022] [Accepted: 06/15/2022] [Indexed: 11/16/2022] Open
Abstract
This study was designed to evaluate the effects of different dietary levels of cassava starch extraction residue meal (CReM) on egg production, egg quality, oxidative status, egg yolk fatty acid profile, and hepatic expression of fatty acid metabolism-related genes. In total, 288 Longyan laying ducks aged 21 wk with similar BW were randomly assigned to 4 dietary treatments, each consisting of 6 replicates of 12 birds. The birds were fed a typical corn-soybean meal diet, which contained 0% (control), 5%, 10%, and 15% CReM, mainly replacing wheat bran, and the experiment lasted for 16 wk. The tested CReM levels did not show significant effects on the egg production, nonmarketable egg percentage, egg weight, daily egg mass, and FCR (g feed: g egg), but daily feed intake was reduced with increased CReM level (linear P < 0.001, quadratic P < 0.05). Yolk color increased (linear and quadratic, P < 0.01) with the increase in CReM level, but the Haugh unit, yolk proportion, albumen proportion, shell proportion, eggshell thickness, and eggshell strength were unaffected. Yolk contents of C11:0 and C12:0 (linear, quadratic, P < 0.01) and total saturated fatty acids increased, and the C22:1 level decreased (linear P < 0.01, quadratic P < 0.05) with the increase in CReM level, but the total monounsaturated fatty acids, the individual and total polyunsaturated fatty acids and n−6 and n−3 fatty acids, triglycerides, and total cholesterol in egg yolk were not affected. Hepatic gene expression revealed a significant increase in peroxisome proliferators-activated receptors γ (linear, quadratic, P < 0.001), but the expression of fatty acid synthase, sterol regulatory element binding protein 1 and apolipoprotein A1 genes were unaffected by CReM level. In conclusion, the results of the current study indicated that the CReM could be included up to 15% in laying duck diets without negative effects on the egg-laying rate, egg quality, and oxidative status. Dietary inclusion of CReM increased the yolk content of total saturated fatty acids and SOD activity in the liver.

Abstract
Objective: To assess the taste function of healthy Chinese adults with the reliable whole-mouth taste test, and to analyze the correlation of taste function with age and gender. Methods: The clinical data of 584 participants reporting the normal sense of smell and taste from March 2019 to January 2020 in the Physical Examination Center of Beijing Anzhen Hospital were analyzed in the study, including 297 males and 287 females, aging (46.9±16.6) years. The subjects were divided into youth group (19-35 years old), middle aged group (36-50 years old), middle-elderly aged group (51-65 years old) and elderly group (66-80 years old). The taste test involved 5 tastants (sour, sweet, salty, umami and bitter) and 7 concentrations. The perception and recognition scores of five tastes were obtained through the whole-mouth taste test. SPSS 22.0 software was used for statistical analysis. Results: The intra-class correlation coefficients of the whole-mouth taste test were 0.751 to 0.828, which showed high test-retest reliability. The total score of perception and recognition of five tastes showed the significant negative correlation with age (r value was -0.49 and -0.44, respectively, both P<0.001). Compared with the other two groups, taste function of middle-elderly aged and elderly group decreased significantly (all P<0.001). There was no significant difference in total perception scores and total recognition scores between youth and middle aged group (all P>0.05). The perception scores and recognition scores of sour, salty, umami, bitter and total scores in females were higher than those in males (all P<0.05), but there was no significant difference in perception scores and recognition scores for sweet between them (P value was 0.584 and 0.223, respectively). Conclusions: The taste function is significantly negatively correlated with age. Except the sweet, females are more sensitive to the sour, salty, umami and bitter tastes than males.

Abstract
Objective: To observe the changes of olfactory function, intranasal trigeminal nerve function and taste function in patients with upper respiratory tract post-viral olfactory dysfunction (PVOD), and to explore the correlation of chemosensory function. Methods: The clinical data of 42 patients with PVOD who visited to the Olfactory and Taste Center of Otorhinolaryngology Head and Neck Surgery Department of Beijing Anzhen Hospital from January to December of 2019 were analyzed retrospectively, including 20 males and 22 females, aging (48.86±11.47) years (x¯). Twenty subjects in normal control group were selected according to the sex ratio of PVOD patients. Sniffin' Sticks olfactory tests were performed on the subjects, including threshold test (T), discrimination test (D) and identification test (I), and the sum of the above three test scores was the TDI value. At the same time, olfactory event-related potentials (oERPs), trigeminal event-related potentials (tERPs) and taste function test were performed. According to the taste function test, the patients were divided into normal gustation (NG) group and gustatory dysfunction (GD) group. The results of olfaction, taste and intranasal trigeminal nerve function tests were compared among different groups, and the correlation analysis was carried out. SPSS statistical software was used for statistical analysis. Results: GD was present in 14 (33.3%) of 42 PVOD patients with a course of PVOD of 5 (3, 6) months (M (Q1, Q3)). The gustatory function of patients with PVOD was related to gender (r=0.565, P<0.001), smoking status (r=-0.512, P=0.001), duration (r=-0.357, P=0.020) and olfactory function (all P<0.05). The olfactory function of GD group was worse than that of NG group, and the differences of TDI value and T value between the two groups were statistically significant (10.25±4.58 vs 13.35±3.61, 1.54±0.66 vs 2.10±0.88, t value was 2.40 and 2.10 respectively, both P<0.05). The amplitudes of oERPs and tERPs were significantly lower in GD group than those in NG group (all P<0.05). Conclusion: In patients with PVOD, the subjective and objective olfactory function, intranasal trigeminal nerve function and taste function were decreased, and there was a correlation, suggesting that there was a synergistic effect between the chemosensory functions of PVOD patients.

Abstract
Objective: To analyze the effects of community-based interventions for diabetic eye diseases in Xinjing community, Shanghai from 2016 to 2018. Methods: Based on the project of "Establishment of Service Model for Comprehensive Prevention and Treatment of Diabetic Eye Diseases in Shanghai", the participants were not suffering diabetic retinopathy (DR) in Xinjing community in 2016 before interventions and received community-based interventions for diabetic eye diseases. The incidence of DR, visual acuity and awareness of DR were used as evaluation indicators to analyze the effects of interventions for diabetic eye diseases in the community. Results: A total of 537 patients were included in this study, the incidence of DR among diabetic patients in Xinjing community was 7.6% after interventions. The duration of diabetes (OR= 1.065) and HbA1c (OR= 1.090) were the risk factors of DR. Before and after the interventions, the patients with monocular low vision and binocular low vision were 27 cases (5.0%), 8 cases (1.5%), 19 cases (3.5%) and 7 cases (1.3%) respectively. After interventions, the awareness on the prevention and treatment of DR increased significantly, and the proportion of regular visits to ophthalmology examination, diet control and physical exercise also increased significantly. Conclusion: Community-based interventions for diabetic eye diseases are helpful to improve the awareness of DR prevention and control, reduce the incidence of DR.

Abstract
This study evaluated the effects of selenium (Se) supplementation in maternal and offspring diets on performance and antioxidant capacity of ducklings aged from 0 to 2 wk. A total of 144 female Longyan duck breeders aged 22-wk were allotted into 2 treatments and fed a control diet or a 0.16 mg Se/kg supplemented diet. At 40-wk, 120 offspring from each treatment were divided into 2 groups, with 6 replicates of 10 birds. Using a 2 × 2 factorial design, ducklings from each maternal dietary treatment were assigned to a control diet or a 0.16 mg Se/kg supplemented diet from hatch to 2-wk. Compared with Se-deficient diet, maternal diet supplemented with 0.16 mg Se/kg increased the BW of hatchlings (P < 0.01). There were interactions between maternal and progeny diet with 0.16 mg Se/kg in BW of ducklings aged 2 wk and BW gain (BWG) as ducklings from maternal Se/progeny none treatment had the lightest BW and BWG (P < 0.01). Maternal diet with 0.16 mg Se/kg decreased plasma concentration of uric acid and insulin-like growth factor 1 (P < 0.01), and progeny diet supplemented with 0.16 mg Se/kg increased the activities of glutathione peroxidase 3 (GPx3) in plasma and glutathione peroxidase 1 in erythrocyte (P < 0.01). Maternal diet with 0.16 mg Se/kg increased (P < 0.05) the hepatic activity of total superoxide dismutase (T-SOD). Progeny diet supplemented with 0.16 mg Se/kg increased (P < 0.01) hepatic activity of GPx3 and decreased (P < 0.01) the hepatic concentration of malondialdehyde. Interactions were detected between maternal and progeny diet with 0.16 mg Se/kg in hepatic activity of T-SOD and maternal and progeny diet supplemented with Se displayed the highest hepatic activity of T-SOD (P < 0.05). Overall, Se supplementation in the diet of duck breeders and offspring increased the antioxidant capacity of ducklings. Maternal Se supplementation increased the BW of hatchlings, whereas maternal and progeny dietary Se supplementation did not affect the BWG of ducklings aged from 0 to 2 wk. Se supplementation with additional 0.16 mg/kg in the diet of duck breeders and offspring displayed beneficial effects particularly on the antioxidant capacity in ducklings.

Abstract
This study aimed to determine the dietary tryptophan (Trp) requirement for laying duck breeders. A total of 504 Longyan duck breeders (body weight: 1.20 ± 0.02 kg) aged 22 wk were randomly allocated to 6 treatments, each with 6 replicates of 14 ducks. During the next 16 wk, birds were fed the basal diet with total Trp contents of 1.00, 2.00, 3.00, 4.00, 5.00 and 6.00 g/kg, respectively. Dietary Trp levels increased egg production, egg mass and feed intake of duck breeders from 22 to 37 wk (P < 0.05), and there were linear and quadratic effects of Trp level (P < 0.05). The feed conversion ratio (FCR) quadratically decreased with dietary Trp levels (P < 0.05). Dietary Trp levels decreased (P < 0.05) egg albumen height and Haugh unit at wk 8 or 12, and the responses were linear and quadratic (P < 0.05). The body weight of breeders, absolute and relative weight of oviduct, number and total weight of preovulatory follicles (POF), and its proportion relative to ovarian weight were increased (P < 0.05), and the responses were linear (P < 0.01) and quadratic (P < 0.001). Ovarian weight increased quadratically (P < 0.05), and the mean weight of POF increased (P < 0.05), linearly and quadratically. The proportion of small yellow follicles relative to ovary weight decreased (P < 0.01) linearly and quadratically. At wk 16 of the trial period, the serum albumin content and alanine aminotransferase activity decreased (P < 0.05) and the creatinine content increased (P < 0.01) linearly and quadratically. The Trp requirements were estimated to be 3.14 g/kg for optimizing egg production, 2.93 g/kg for egg mass, and 2.92 g/kg for FCR. Overall, dietary Trp levels (1 to 6 g/kg) affected productive performance, egg quality, reproductive organ and ovarian follicle development, and serum biochemical indices of layer duck breeders, and a diet containing 2.9 to 3.1 g Trp per kg feed was adequate during the laying period (22 to 37 wk of age).

Abstract
This study was aimed at studying use of reduced dietary crude protein (CP) level supplemented with additional amino acids in laying ducks. A total of 720 Jingjiang ducks (50 wk) were randomly assigned to 5 treatments and fed 5 basal diets with CP levels at 17.5, 16.5, 15.5, 14.5, or 13.5%, with additional amino acids added to each diet for 12 wk. Each treatment had 6 replicates of 24 ducks each. Dietary CP levels affected (P < 0.05) egg production and mass of laying ducks, and there was a linear and quadratic decrease with decreasing CP levels (P < 0.05). Dietary CP levels did not affect egg weight and feed conversion ratio (FCR), but egg weight decreased linearly (P < 0.05); FCR increased linearly and quadratically (P < 0.05) with decreasing CP levels. There were no significant differences in egg quality among the different CP levels (P > 0.05). Ovarian weight, total and mean weight of preovulatory follicles, and total weight of small yellow follicles (SYF) were decreased by dietary CP levels (linear, P < 0.01 and quadratic, P < 0.05). The oviductal weight decreased linearly (P < 0.05), and the number of SYF decreased linearly and quadratically with decreasing CP levels (P < 0.05). The serum estradiol content decreased linearly with dietary CP levels (P < 0.05). The serum contents of luteinizing hormone, prolactin, and progesterone decreased (P < 0.05), linearly and quadratically (both P < 0.01) with decreasing CP levels. The serum contents of creatinine (CRE), triglycerides (TG), total cholesterol (TC), and alanine aminotransferase (ALT) activity were affected (P < 0.05) by different dietary CP levels. The total protein content increased linearly (P < 0.05), TC content increased quadratically (P < 0.05), and contents of albumin, CRE, TG, and phosphorus, and activities of aspartate aminotransferase and ALT increased linearly and quadratically (both P < 0.05) with decreasing CP levels. Overall, reduced dietary CP levels with addition of amino acids affected the laying performance, the development of reproductive organs and ovarian follicles, serum hormones, and biochemical indices of laying ducks. Dietary CP levels can be reduced to 14.5% with additional amino acid supplementation for 12 wk in laying ducks without negative effect on laying performance and egg quality.

Abstract
Objective: The efficacy and safety of adjunctive magnetic seizure therapy (MST) for patients with schizophrenia are unclear. This systematic review was conducted to examine the efficacy and safety of adjunctive MST for schizophrenia. Methods: Chinese (WanFang and Chinese Journal Net) and English (PubMed, EMBASE, PsycINFO, and the Cochrane Library) databases were systematically searched. Results: Two open-label self-controlled studies (n = 16) were included and analyzed in this review. In these studies, the Positive and Negative Syndrome Scale (PANSS) total scores and Brief Psychiatric Rating Scale (BPRS) total scores significantly decreased from baseline to post-MST (all Ps < 0.05), without serious adverse neurocognitive effects. Mixed findings on the neurocognitive effects of adjunctive MST for schizophrenia were reported in the two studies. A discontinuation rate of treatment of up to 50% (4/8) was reported in both studies. The rate of adverse drug reactions (ADRs) was evaluated in only one study, where the most common ADRs were found to be dizziness (25%, 2/8) and subjective memory loss (12.5%, 1/8). Conclusion: There is inconsistent evidence for MST-related adverse neurocognitive effects and preliminary evidence for the alleviation of psychotic symptoms in schizophrenia.

Effects of capsaicin on laying performance, follicle development, and ovarian antioxidant capacity in aged laying ducks. Poult Sci 2020; 100:100901. [PMID: 33667870 PMCID: PMC7933805 DOI: 10.1016/j.psj.2020.11.070] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 11/12/2020] [Accepted: 11/23/2020] [Indexed: 11/26/2022] Open
Abstract
The present study was conducted to evaluate the effects of dietary addition of capsaicin (CAP) on egg production performance, follicular development, and ovarian antioxidant capacity in laying ducks. Three hundred seventy eight 58-wk-old laying ducks were randomly divided into 3 treatments, each treatment consisted 6 replicates, with 12 individually caged laying ducks per replicate. Ducks fed a basal diet served as control, the other 2 groups of ducks were fed the same diet containing 150 mg/kg CAP but in the manner of feed restriction (pair-fed) or ad libitum fed. The experiment lasted for 8 wk. The results showed that the dietary supplementation with CAP under conditions of ad libitum feeding increased feed intake (P < 0.001) and tended (P < 0.1) to increase egg production and egg weight in laying ducks but had no effects on daily egg mass and feed conversion ratio. The relative weight of large yellow follicles from the 2 CAP-supplemented groups at 64 wk of age were significantly higher than that of the controls (P = 0.01). The relative weight of the small yellow follicles in the CAP free-fed group was significantly higher than that of the other 2 groups (P < 0.01). Capsaicin supplementation under ad libitum feding conditions tended to increase the number of dominant follicles in laying ducks (P = 0.06). The ovarian mRNA expression of genes related to calcium signaling (TRPV4, ATP2A2, ITPR1, and CaM) in the CAP ad libitum fed groups were significantly higher than those of the other 2 groups (P < 0.05). The ovarian mRNA expression of CDK1 in CAP free-fed ducks was significantly higher than that of the other 2 groups (P = 0.01). Capsaicin supplementation significantly increased the plasma glutathione peroxidase activity (P < 0.01) in comparison with the control group but reduced the malondialdehyde content in the ovaries of laying ducks (P < 0.01). The results of this study indicates that dietary supplementation of CAP increased feed intake and improved egg production performance probably by activating calcium signaling pathway and improving redox status.

Estimation of dietary manganese requirement for laying duck breeders: effects on productive and reproductive performance, egg quality, tibial characteristics, and serum biochemical and antioxidant indices. Poult Sci 2020; 99:5752-5762. [PMID: 33142493 PMCID: PMC7647759 DOI: 10.1016/j.psj.2020.06.076] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2020] [Revised: 06/11/2020] [Accepted: 06/25/2020] [Indexed: 01/05/2023] Open
Abstract
This study was aimed at estimating the dietary manganese (Mn) requirement for laying duck breeders. A total of 504 Longyan duck breeders (body weight: 1.20 ± 0.02 kg) aged 17 wk were randomly allocated to 6 treatments. The birds were fed with a basal diet (Mn, 17.5 mg/kg) or diets supplemented with 20, 40, 80, 120, or 160 mg/kg of Mn (as MnSO4·H2O) for 18 wk. Each treatment had 6 replicates of 14 ducks each. As a result of this study, dietary Mn supplementation did not affect the productive performance of laying duck breeders in the early laying period (17–18 wk), but affected egg production, egg mass, and feed conversion ratio (FCR) from 19 to 34 wk (P < 0.05), and there was a linear and quadratic effect of supplement level (P < 0.05). The proportion of preovulatory ovarian follicles increased (P < 0.01) linearly and quadratically, and atretic follicles (weight and percentage) decreased (P < 0.05) quadratically with dietary Mn supplementation. The density and breaking strength of tibias increased (quadratic; P < 0.05), the calcium content of tibias decreased (linear, quadratic; P < 0.01), and Mn content increased (linear, quadratic; P < 0.001) with increase in Mn. The addition of Mn had a quadratic effect on serum contents of estradiol, prolactin, progesterone, luteinizing hormone, and follicle-stimulating hormone (P < 0.001). Dietary Mn supplementation decreased serum contents of total protein (linear, P < 0.05), glucose (quadratic, P < 0.05), total bilirubin, triglycerides, total cholesterol, low-density lipoprotein cholesterol, and calcium (linear, quadratic; P < 0.05). The serum total antioxidant capacity and total and Mn-containing superoxide dismutase activities increased (linear, quadratic; P < 0.001), and malondialdehyde content decreased (linear, quadratic; P < 0.001) in response to Mn supplemental levels. The dietary Mn requirements, in milligram per kilogram for a basal diet containing 17.5 mg/kg of Mn, for Longyan duck breeders from 19 to 34 wk of age were estimated to be 84.2 for optimizing egg production, 85.8 for egg mass, and 95.0 for FCR. Overall, dietary Mn supplementation, up to 160 mg/kg of feed, affected productive performance, tibial characteristics, and serum biochemical and antioxidant status of layer duck breeders. Supplementing this basal diet (17.5 mg/kg of Mn) with 85 to 95 mg/kg of additional Mn was adequate for laying duck breeders during the laying period.

The effects of dietary Se on productive and reproductive performance, tibial quality, and antioxidant capacity in laying duck breeders. Poult Sci 2020; 99:3971-3978. [PMID: 32731984 PMCID: PMC7597912 DOI: 10.1016/j.psj.2020.04.006] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 02/20/2020] [Accepted: 04/01/2020] [Indexed: 12/17/2022] Open
Abstract
This study evaluated the optimal concentrations of dietary Se for the productive and reproductive performance, tibial quality, and antioxidant status in duck breeders aged 23 to 49 wk. In total, 432 Longyan duck breeders aged 22 wk were allotted randomly to 6 treatments, each with 6 replicates of 12 individually caged birds. The experiment lasted for 27 wk, and birds were fed corn-soybean meal-based diets containing 0.11, 0.19, 0.27, 0.35, 0.43, or 0.51 mg Se/kg, respectively. The tested dietary Se levels did not affect egg production and tibial quality of duck breeders. The Se contents of the shell, yolk or albumin, whole egg, and the fertility of set eggs increased in a linear and quadratic manner (P < 0.05) in response to the increased dietary Se level, whereas the yolk malondialdehyde (MDA) and embryonic mortality decreased. The activities of glutathione peroxidase 3 (Gpx3) in plasma and Gpx1 in the erythrocytes and livers of breeder ducks increased in a linear and quadratic manner (P < 0.05) in response to increased dietary Se levels, whereas the total superoxide dismutase (T-SOD) activity increased and the MDA concentration decreased in the liver. The activity of Gpx3 in the plasma and Gpx1 in the erythrocytes and livers of newly hatched ducklings increased linearly (P < 0.01) with the increase in Se level, whereas the T-SOD activity and MDA concentration did not change. In conclusion, diets containing 0.27 mg Se/kg led to the highest egg fertility and hatchability in Longyan duck breeders, and using levels >0.19 mg Se/kg diet enhanced the antioxidant capacity in breeders and their offspring. The regression model indicated that dietary Se levels 0.19, 0.27, 0.28, 0.24, and 0.30 mg/kg are optimal levels to obtain maximum Se deposition efficiency in eggs, egg fertility, Gpx1 activity in erythrocytes and liver in duck breeders, and plasma activity of Gpx3 in newly hatched ducklings, respectively.

Abstract
OBJECTIVE Ketamine and propofol have become increasingly popular in electroconvulsive therapy (ECT) anaesthesia. This study was conducted to examine whether changes in serum levels of brain-derived neurotrophic factor (BDNF) are associated with the antidepressant effects of ketofol, a combination of ketamine and propofol, in ECT for patients with treatment-resistant depression (TRD). METHODS Thirty patients with TRD (18-65 years) were enrolled and underwent eight ECT sessions with ketamine (0.5 mg/kg) plus propofol (0.5 mg/kg) (ketofol). Symptom severity was monitored using the 17-item Hamilton Depression Rating Scale (HAMD-17) and the Brief Psychiatric Rating Scale (BPRS), and serum levels of BDNF were examined by enzyme-linked immunosorbent assay (ELISA) at baseline and after 2, 4, and 8 ECT treatments. Serum levels of BDNF were also collected from thirty healthy controls. RESULTS At baseline, there were no significant differences in serum levels of BDNF between patients with TRD and healthy controls. The response and remission rates in patients with TRD were 100% (30/30) and 53.3% (16/30) after ECT treatment, respectively. Despite a significant reduction in HAMD-17 and BPRS scores after ECT, no changes in serum levels of BDNF were observed after ECT treatment when compared to baseline. No association was found between serum levels of BDNF and changes in illness severity. CONCLUSION Serum levels of BDNF did not represent a suitable candidate biomarker for determining the antidepressant effects of ketofol during ECT for patients with TRD.

Abstract
BACKGROUND Many studies have indicated a sex-specific effect in many aspects of schizophrenia. The presence of depressive symptomatology exists in all phases of schizophrenia. The aim of this study is to investigate the sex differences in the proportion of comorbid depressive symptoms and sex-specific relationships between depressive symptoms and clinical correlates in never-treated Chinese patients with first-episode schizophrenia (NTFE patients), which have not been reported yet. METHODS Via a cross-sectional design, 240 NTFE inpatients (male/female = 111/129) between ages 16 and 45 years and meeting DSM-IV-TR criteria of schizophrenia were recruited. The Positive and Negative Syndrome Scale (PANSS) was used for the psychopathology, and the 17-item Hamilton Depression Rating Scale (HDRS-17) for the comorbid depressive symptoms. This study was conducted from June 2013 to December 2015. RESULTS The proportion of patients with depressive symptoms (total score on HDRS-17 ≥ 8) in men was significantly higher than in women (male: 62.2%, female: 48.1%; χ²₁ = 4.28, P = .039). Male patients had significantly greater depressive symptoms as shown on the HDRS-17 than female patients (t1, 238 = 2.75, P = .006). Further, we found that age, the age at onset, smoking rate, and PANSS total and general psychopathology, negative symptoms, and cognitive factor subscores favored significant sex differences in female patients (all P < .05). Interestingly, we found sex differences in the correlation between the HDRS-17 score and clinical phenotype, showing that in male patients, the PANSS general psychopathology subscore (β = 0.75, t = 7.72, P < .001) and total score (β = 0.44, t = 4.81, P < .001) significantly predicted the HDRS-17 total score, while in female patients, the PANSS general psychopathology subscore (β = 0.74, t = 8.45, P < .001), total score (β = 0.47, t = 5.71, P < .001), and cognitive factor subscore (β = 0.24, t = 2.60, P < .001) significantly predicted the HDRS-17 total score. CONCLUSIONS Our results indicate sex differences in the frequency and severity of comorbid depressive symptoms and in associations between depressive symptoms and clinical correlates in NTFE patients.

Abstract
Objective: To evaluate the effects of percutaneous nephrolithotomy (PNL) in the treatment of medullary sponge kidney with calculi. Methods: A total of 77 patients (91 renal units) of medullary sponge kidney with calculi (MSK group) and 77 patients (77 renal units) with common kidney stone (control group) received PNL at Department of Urology in Peking University People's Hospital from September 2006 to February 2016 were analyzed retrospectively. The MSK group included 33 males and 44 females with a mean age of (42.1±13.2) years, the mean stone burden was (3.9±1.8) cm. The control group included 36 males and 41 females with a mean age of (45.3±13.0) years, the mean stone burden was (3.6±1.5) cm. The numbers of tracts, the time of operation, the drop of hemoglobin, the change of creatine, the time of hospitalization, the stone free rate and major complications were compared between the two groups. The measurement data and numeration data were compared with t test and χ(2) test. Results: There were no significant differences in sex, age, preoperative urinary tract infection, stone type, and stone burden between the two groups (all P>0.05). The proportion of bilateral renal calculus in MSK group was higher (18.2% vs. 0, χ(2)=15.400, P=0.000). There were 159 percutaneous channels were established in MSK group while 90 percutaneous channels were established in control group. Compared with the control group, the operation time ((88.1±37.5) minutes vs. (68.5±30.1) minutes, t=3.543, P=0.000) and hospitalization time ((15.1±8.3) days vs. (10.1±3.6) days, t=4.816, P=0.000) were longer, the creatinine level increased ((101.2±62.6) μmol/L vs. (71.3±23.6) μmol/L, t=3.777, P=0.000), the rate of stone free decreased (27.5% vs. 83.1%, χ(2)=51.840, P=0.000) and the rate of complications increased (29.9% vs. 11.7%, χ(2)=8.114, P=0.004) in MSK group. There was no statistically difference in hemoglobin drop ((12.5±13.2) g/L vs. (13.0±10.9) g/L, t=-0.260, P=0.795). Conclusions: Using PNL for patients of MSK with calculi has a lower stone free rate and a higher complications. It is an effective method for patients of MSK with large and complex calculi.

Abstract
Objective:To evaluate the efficacy and economics of sublingual immunotherapy (SLIT) with Dermatophagoides farinae drops in patients with allergic rhinitis and allergic asthma. Method:Two hundred and three patients (aged 4-60 yr) with allergic rhinitis and allergic asthma induced by house dust mites were retrospectively analyzed. Eighty-six patients were treated by SLIT with standardized Dermatophagoides farina drops and pharmacotherapy (SLIT group), while 117 patients were treated by standardized pharmacotherapy (drug group). Patients were followed up for 2 years with one visit in every 3 months. Total nasal syptom score (TNSS), total rhinitis medicine score (TRMS), daytime asthma syptom score (DASS), nighttime asthma syptom score (NASS), total asthma medicine score (TAMS) and treatment charge were recorded at each visit. Result:There was no significant difference between two groups in TNSS, TRMS, DASS, NASS, TAMS before treatment (all P>0.05). After 1-year or 2-year duration, there were significant differences between the SLIT group and drug group in TNSS, TMSS, DASS, NASS, TAMS (all P<0.01). After 1-year or 2-year duration, the symptom scores and medication scores of SLIT group significantly decreased compared with those before treatment (all P<0.01). In terms of treatment charge, although direct cost of SLIT group was a little higher than that of drug group, the indirect cost of SLIT group was remarkably lower than that of drug group, showing significant difference (P<0.01). Conclusion:SLIT with Dermatophagoides farinae drops is effective in patients with allergic rhinitis and allergic asthma, which may also reduce indirect cost.

The particulate passage rate, nutrient composition and fermentation characteristics across gastrointestinal tracts in lactating dairy cows fed three different forage source diets. J Anim Physiol Anim Nutr (Berl) 2018; 102:861-868.

Abstract
This study was conducted to investigate the particulate passage rate, nutrient characteristics and fermentation parameters across the gastrointestinal tract (GIT) in lactating dairy cows fed cereal straws in comparison with alfalfa hay. Eighteen multiparous Holstein cows were randomly assigned to one of three experimental diets consisting of 55% concentrate, 15% corn silage and 30% different forage sources as follows (% of dry matter [DM]): (i) 23% alfalfa hay and 7% Chinese wild rye hay (AH); (ii) 30% corn stover (CS); and (iii) 30% rice straw (RS). The Cr-mordanted corn silage-neutral detergent fibre was used to estimate the passage flow at week 14. After 14-week feeding, the animals were slaughtered to collect the gastrointestinal digesta. Dietary forage sources had little effect on the fractional passage rates in the rumen (range from 5.05 to 6.25%/hr) or hindgut (range from 4.49 to 5.24%/hr). Total volatile fatty acid (VFA) concentration in the caecum was highest, followed by the rumen, colon and rectum, and the lowest in the abomasum and duodenum, indicating that the large intestines, especially caecum, are the important positions for carbohydrate degradation. Greater proportion of propionate and butyrate and lower acetate were found in the AH compared to CS or RS in colon, but higher acetate in abomasum was found in the cows fed CS or RS compared to AH. In conclusion, cereal straw diets did not change the particulate passage rate in the rumen and hindgut which might be mainly due to the similar DM intake among these three diets. Different forage source diets significantly changed VFA proportion in the abomasum and colon, indicating the existence of different digestion or absorption rates in these tracts among the experimental diets.

Abstract
OBJECTIVE To investigate the position and the size of ureteral stone in patients before treated with ureteroscopic lithotripsy or percutaneous nephrolithotomy (PCNL), as well as the dilatation of ureter caused by stone, which may be helpful for better understanding of pathogenesis of ureteral stone and improvement of the diagnosis and treatment in clinic. METHODS A total of 129 cases with ureteral stone for endourologic lithotripsy in Peking University People's Hospital from Aug. 2016 to Mar. 2017 were included for the retrospective review. The CT data of the ureteral stones and the ureteral dilatation were collected, including the position of stone, the transverse and longitudinal diameter of stone, and the transverse diameter of dilated upper ureter and ureteropelvic junction (UPJ). The distribution of ureteral stones and dilatation in different parts of ureter were compared and analyzed. RESULTS All of the 129 cases of ureteral stone, stones were located at UPJ in 9 cases (7.0%), proximal ureter in 75 (58.0%), ureter crossing external iliac vessel (UEIV) in 6 (4.7%), distal ureter in 26 (20.2%), and ureterovesical junction (UVJ) in 13 (10.1%). The mean transverse diameter of proximal ureteral stones was greater than that of distal ureteral stones [(8.47±2.36) mm vs. (6.74±1.99) mm, P<0.001], as the same as the mean longitudinal diameter [(11.00±4.41) mm vs. (7.50±4.28) mm, P<0.001]. In 114 cases of dilated ureter for stone, the UPJ had a greater transverse diameter compared with the upper ureter [(14.39±6.09) mm vs. (11.45±3.85) mm, P<0.001]. CONCLUSION The most common location of stone is the proximal ureter in patients for endourologic lithotripsy, as the location in UEIV is rare. Both transverse and longitudinal diameters of stone in proximal ureter are greater than those in distal ureter. For dilated ureter, it is more severe in UPJ than in upper ureter. Traditionally, it is accepted that the stones lodge at 3 sites of natural narrowing in ureter, which may be questioned.

Abstract
OBJECTIVE To evaluate the clinical effect and safety of retroperitoneal laparoscopic surgery combined with mini-flank incision "hybrid surgery" for partial nephrectomy of complex renal tumors. METHODS Between April 2015 and December 2016, the clinical data from 16 patients with complex renal tumors who underwent the "hybrid surgery", including 10 males and 6 females, were retrospectively reviewed. The average age was (50.2±10.7) years, 9 cases were located in the left side and 7 cases in the right side, the mean tumor size was (6.1±1.0) cm, and the mean R.E.N.A.L. nephrometry score was 9.3±1.3. All the patients received the "hybrid surgery", the first step was to adequately mobilize the kidney and tumor, prepared the renal artery by retroperitoneal laparoscopy, and then the incision about 10-12 cm was done under the twelve rib to convert to open surgery. After the renal artery was clamped, the tumor was removed and the wound was closed under direct vision. The operative time, ischemia time, estimated blood loss, intraoperative and postoperative complications and short-term renal function were recorded. RESULTS All the 16 patients' "hybrid surgeries" were successfully performed. The mean operative time was (164.9±23.6) min, mean ischemia time was (32.4±6.2) min, and mean estimated blood loss was (204.0±125.1) mL. The mean drainage tube removal time was (4.1±1.0) d, and the mean postoperatively hospital stay was (6.9±1.5) d. There were 2 patients with Clavien III grade complications. One patient was injured with collecting system, and 1 patient received a second emergency surgery for acute postoperative bleeding. The mean 1 day postoperative serum creatinine level was (126.3±26.4) μmol/L, which was statistically significant (P<0.05) compared with the preoperative serum creatinine level(74.3±16.9)μmol/L. There were no significant differences (P>0.05) in comparing the 1 month postoperative serum creatinine level (92.6±18.2) μmol/L, 3 months postoperative serum creatinine level (80.8±18.4) μmol/L with the preoperative serum creatinine level. During 3 to 20 months follow-up periods, no local recurrence or distant metastasis occurred. CONCLUSION This "hybrid surgery" combined retroperitoneal laparoscopic surgery with mini-flank incision for partial nephrectomy is safe and effective. It could decrease the operative difficulty and be worthy of further application for some selected complex renal tumor patients.

Biological and ecological evidences suggest Stipa krylovii (Pooideae), contributes to optimal growth performance and population distribution of the grasshopper Oedaleus asiaticus.

Abstract
Oedaleus asiaticus Bey. Bienko is a significant grasshopper pest species occurring in north Asian grasslands. Outbreaks often result in significant loss in grasses and economic losses. Interestingly, we found this grasshopper was mainly restricted to Stipa-dominated grassland. We suspected this may be related to the dominant grasses species, Stipa krylovii Roshev, and hypothesized that S. krylovii contributes to optimal growth performance and population distribution of O. asiaticus. A 4 year investigation showed that O. asiaticus density was positively correlated to the above-ground biomass of S. krylovii and O. asiaticus growth performance variables (survival rate, size, growth rate) were significantly higher in Stipa-dominated grassland. A feeding trial also showed that O. asiaticus had a higher growth performance when feeding exclusively on S. krylovii. In addition, the choice, consumption and the efficiency of conversion of ingested food (ECI) by O. asiaticus was highest for S. krylovii compared with other plant species found in the Asian grasslands. These ecological and biological traits revealed why O. asiaticus is strongly associated with Stipa-dominated grasslands. We concluded that the existence of S. krylovii benefited the growth performance and explained the distribution of O. asiaticus. These results are useful for improved pest management strategies and developing guidelines for the monitoring of grasshopper population dynamics against the background of vegetation succession and changing plant communities in response to activities such as grazing, fire and climate change.

Abstract
OBJECTIVE To compare various data of open pyeloplasty, laparoscopic pyeloplasty and endopyelotomy as a treatment of ureteropelvic junction obstruction (UPJO), and to investigate and discuss the feasibility and effect of the three methods. METHODS In the study, 109 cases of UPJO treated by different surgical approaches in Peking University People's Hospital from January 2004 to December 2014 were retrospectively investigated. The patients were divided into three groups according to the treatment they received: open peyloplasty group (32 cases), laparoscopic peyloplasty group (31 cases) and endopyelotomy group (46 cases).We compared the data of the operative time, intraoperative blood loss, perioperative complications and post-operative hospital stay among the three groups. The mean follow-up time was(51.9±40.1) months (6-132 months). RESULTS None of the laparoscopic peyloplties was converted to open peyloplasty. All endpyelotomies were successfully completed. The operative time was as follows: laparoscopic peyloplasty group (195.97±55.22) min, open peyloplasty group (121.19±33.95) min and endopyelotomy group (74.04±33.95) min,and there were significant differences among the three groups respectively(P<0.001). There was no significant difference on the operative blood loss between open peyloplasty group and laparoscopic peyloplasty group (P=0.163). The operative blood loss of endopyelotomy group was 5(0,310)mL,which was lower than the other two groups, and this result had significant differences with the other two groups respectively(P<0.001). There were significant differences on the post-operative hospital stay (days) among open peyloplasty group, laparoscopic peyloplasty group and endopeylotomy group (P<0.05,respectively).The success rate was comparable between open peyloplasty group and laparoscopic peyloplasty group( 93.8% vs. 90.3%, P=0.672), while the endopeylotomy group had a lower success rate compared with both open surgery group and laparoscopic group(69.6% vs. 93.8%, P=0.01; 69.6% vs. 90.3%, P=0.048, respectively). The complication rates of open peyloplasty group, laparoscopic peyloplasty group and endopeylotomy group were comparable(15.6%, 16.1% and 13.0%, respectively, P>0.05). CONCLUSION The laparoscopic peyloplasty group had a longer operative time than open peyloplasty group, while its post-operative stay was shorter. There was no significant difference on the operative blood loss between open peyloplasty group and laparoscopic peyloplasty group. Although the success rate of endopyelotomy was lower than those of the other two groups, it had advantages over the aspect of operative time, operative blood loss and post operative stay.

Abstract
OBJECTIVE To evaluate the clinical effect of retroperitoneoscopic renal pedicle lymphatic disconnection via extra-adipose capsule in the management of chyluria and to discuss the management of its complications. METHODS From August 2013 to June 2008, five patients with chyluria were admitted. All the patients were female, aged from 26 to 73 years, and disease course from 1 to 10 years. All the five patients had complained of intermittently voiding milky urine with varying degrees of weight loss, and fatigue, of whom two presented with flank pain and one with anemia. Their urine chyle tests were confirmed to be positive. Preoperative cystoscopy found that chyluria was from the left side in 3 cases,and from the right side in 2 cases. Their proteinuria ranged from + to ++++. All the cases had been treated with the modified procedure by which lymphatic ligation was performed to hilar vessels and proximalureter via extra-adipose capsule without disconnection of perirenal fat tissues. The operation time, intraoperative blood loss, postoperative intestinal function recovery, catheter time, drainage tube removal time and complications during operation were collected. RESULTS All the five cases were performed successfully. The operation time ranged from 75 to 170 minutes, mean (126.0±39.6) minutes, with the intraoperative blood loss 20 to 60 mL, mean (38.0±16.4) mL, and the postoperative intestinal function recovery time 1 to 3 days, mean (1.9±0.4) days. The catheter time was 1 to 4 days, mean (2.1±0.3) days and the drainage tube removal time ranged from 3 to 15 days, mean (9.3±1.8) days. Postoperatively lymphorrhagia was found in two cases. No renal vessels injury occurred during operation. Chyluria of all the patients disappeared on the operation day with negative chyluria test after surgery. Furthermore, urine test revealed that proteinuria was totally negative. No recurrence was detected in our patients in the 9 to 31 months' follow-up. CONCLUSION This modified procedure does not have to disconnect perirenal fat tissues and nephropexy during operation. It was characterized with shorter operation time, definitive effect and fewer complications.

Abstract
OBJECTIVE To evaluate the risk factors of systemic inflammatory response syndrome (SIRS) in the patients with type 2 diabetes diagnosed with kidney stone after percutaneous nephrolithotomy (PCNL). METHODS In this study, 461 patients with type 2 diabetes who received PCNL in Peking University People's Hospital from June 2006 to December 2015 were reviewed. There were 281 males and 180 females with an average age of 57 years were included, of whom, 137 were diagnosed with SIRS after PCNL. The demographic data, clinical features, and test results were compared between the patients with SIRS and without SIRS, trying to identify the correlation between their clinical characters and the occurrence of SIRS. RESULTS The SIRS was significantly correlated with the patients' preoperative white blood cell counting (×109/L) [7.76 (4.00-17.96) vs. 6.31 (2.00-17.40), P<0.001], preoperational blood glucose level (mmol/L) [7.30 (3.08-19.90) vs. 6.40 (3.42-16.78), P<0.001], operative time (min) [75 (20-270) vs. 60 (20-200), P<0.001], length of stay (d) [12 (2-46) vs. 11 (3-29), P=0.019], staghorn stones [38.8% (33/85) vs. 27.7% (104/376), P=0.042], and preoperational urinary tract infection [36.8% (50/136) vs. 26.6% (81/304), P=0.032]. There was no significant correlation between the SIRS and the patients' age, body mass index, preoperative hemoglobin level, preoperative serum creatinine, and transfusion. In multivariate analysis, abnormal preoperative white blood cell counting (OR=3.194, 95% CI: 1.531-6.666, P=0.002), operative time longer than 60 min (OR=1.635, 95% CI: 1.088-2.456, P=0.018), and preoperational blood glucose level higher than normal 7.1 mmol/L were significantly correlated with the presence of SIRS. CONCLUSION The high level of preoperational blood glucose, abnormal preoperative white blood cell counting, and long operative time were significantly correlated with the presence of SIRS in patients with type 2 diabetes after PCNL.

Abstract
OBJECTIVES The aim of this study was to modify vaginal radical hysterectomy (VRH), design a series of surgical instruments specialised for this procedure, and to study the feasibility, morbidity, and outcome of cervical cancer patients treated with modified laparoscopic-assisted radical vaginal hysterectomy (LARVH). MATERIALS AND METHODS A total of 86 patients with early-stage cervical cancer (IB 1-IAl) underwent modified VRH and laparoscopic pelvic lymphadenectomy and para-aortic lymphadenectomy. Special instruments and modified procedures were used in VRH. Data were collected on operating time, blood loss, ureter separation time, nodal count, hospital stay, and complication recurrence and survival rates. RESULTS All patients successfully completed LARVH. Median operating time was 238 minutes, mean blood loss was 283 ml, median time for ureter separation was 18.5 minutes, median time to post-operative exhaustion was 23 hours, urine recovery was 10.3 days, and median hospital stay was 9.2 days. On average, 23.2 lymph nodes were harvested. Except for one case of left internal iliac vein with intraoperative and postoperative complications, no other major complications occurred, particularly no bladder and ureter injury. Surgical margins were negative in all cases. After median follow-up of 46 months, recurrence rate and overall survival for 84 patients were 3.57% and 97.62%, respectively. DISCUSSION Modified VRH with laparoscopic pelvic lymphadenectomy is an oncologically valid alternative for early stage cervical cancer treatment with minimal intraoperative and postoperative complications. The modification of this procedure and special instruments can enhance the feasibility and the safety of treatment.

Abstract
Our aim was to investigate if human oocytes, like mouse oocytes, exhibit spontaneous Ca(2+) oscillations and nuclear translocation of PLC-beta1 prior to germinal vesicle breakdown (GVBD), and to correlate these events with the evolution of chromatin configuration as a landmark for the meiosis resumption kinetics. Human germinal vesicle (GV) oocytes were either loaded with Fluo-3 probe to record Ca(2+) signals or fixed for subsequent fluorescent labeling of both chromatin and PLC-beta1, and immunogold labeling of PLC-beta1. Here for the first time, we show that human oocytes at the GV-stage exhibit spontaneous Ca(2+) oscillations. Interestingly, only oocytes with a large diameter and characterized by a compact chromatin surrounding the nucleolus of the GV could reveal these kind of oscillations. We also observed a translocation of PLC-beta1 from the cytoplasm towards the nucleus during in vitro maturation of human oocytes. Spontaneous calcium oscillations and nuclear translocation of PLC-beta1 may reflect some degree of oocyte maturity. The impact of our results may be very helpful to understand and resolve many enigmatic problems usually encountered during the in vitro meiotic maturation of human GV oocytes.

Abstract
Scutellarin, a flavonoid glycoside, is the primary active ingredient in breviscapine that is a mixture of flavonoid glycosides extracted from a Chinese herb Erigeron breviscapus (Vant.) Hand.-Mazz. The pharmacokinetics of scutellarin and its aglycone conjugated metabolites after intraperitoneal injection and oral administration of breviscapine was investigated in rats. The plasma concentration of scutellarin and scutellarein conjugates in serial samples was measured by validated high-performance liquid chromatography methods. The pharmacokinetic results indicated that scutellarin underwent rapid and extensive biotransformation in vivo. After intraperitoneal injection, scutellarin was absorbed rapidly. The profiles of scutellarin and scutellarein conjugates were fitted to a two-compartment open model. Scutellarin and scutellarein conjugates showed a similar time course. No significant difference in tmax, t0.5(alpha) and t0.5(beta) was observed between scutellarin and scutellarein conjugates (p>0.05). After oral administration, fluctuations were observed in the concentration-time profiles of both scutellarin and scutellarein conjugates and the pharmacokinetics could not be explained by classical compartment model. The relative bioavailability of oral administration was very low, 10.67 % +/- 4.78% for scutellarin and 7.92% +/- 1.90% for scutellarein conjugates.

Abstract
During the past decade a variety of intrapartum fetal monitors have been constructed that process the entire fetal electrocardiogram (FECG), obtained via a scalp electrode. They therefore differ from conventional monitors in aiming to extract relevant timing and magnitude information from the morphology of the FECG rather than simply the RR interval and hence heart rate. An intrapartum monitor such as this has been successfully developed by ourselves. This paper describes the early results obtained whilst attempting to extend this form of monitoring forward into the antenatal period. In order to achieve this the FECG must be acquired via surface electrodes placed on the maternal abdomen, which yields a signal containing the FECG amidst a number of noise sources. Our investigations into the feasibility of "antenatal abdominal FECG analysis" have been on two fronts. The first has been to produce a bedside monitor similar in function to our intrapartum device, whilst the second has been to address the possibility of performing such monitoring in ambulant subjects. At present the antenatal bedside monitor has successfully extracted and processed the FECG in approximately 75% of the cases studied, with subjects ranging from 20 weeks through to term having been monitored. We also have demonstrated the feasibility of the long term monitoring of maternal and fetal heart rate using a portable instrument.

Abstract
The aim of this study was to demonstrate the acquisition of both the fetal magnetocardiogram (FMCG) and fetal electrocardiogram (FECG) from the abdomen of the same subject. This contrasts with previous reported studies which have generally recorded one or other of these signals but not the two together. Both signals were successfully recorded and averaged to produce a typical complex, thus allowing their direct comparison.
