Effectiveness and safety of Jiawei Xiaoyao pill in the treatment of premenstrual syndrome (liver depression, spleen deficiency, and blood-heat syndrome): a multi-center, randomized, placebo-controlled trial.

OBJECTIVE: To investigate the effectiveness and safety of Jiawei Xiaoyao pill (，JXP) in the treatment of symptoms associated with premenstrual syndrome (PMS). METHODS: A total of 144 regularly menstruating women with PMS were recruited at 8 sites in China from August 2017 to December 2018, and randomized to receive either a JXP or a matching placebo (12 g/d, 6 g twice a day) for 3 menstrual cycles. The primary indicator was the reduced Daily Record of Severity of Problems (DRSP) scores in the luteal phase after 3 months of treatment. The safety outcomes included clinical adverse events (AEs), adverse reactions (ARs), changes in vital signs, and laboratory tests. RESULTS: JXP surpassed the placebo in reducing DRSP scores (psychological/somatic dysfunction) in the luteal phase over 3 menstrual cycles of treatment (PFAS = 0.002, PPPS = 0.001). Additionally, there were no significant differences in the incidence of AEs, severe AEs, withdrawal due to AEs and ARs between the two groups (all P > 0.05), and no clinically significant adverse medical events related to the test drug observed. CONCLUSIONS: JXP was superior to the placebo in relieving the symptoms associated with PMS, which signified that JXP may be effective, safe, and well-tolerated as an alternative therapy.

Enhanced removal of tetracycline from synthetic wastewater using an optimal ratio of co-culture of Desmodesmus sp. and Klebsiella pneumoniae.

A sustainable approach of Desmodesmus sp. GIEC-179: Klebsiella pneumoniae (DUT-XJR-t-1.2) co-culture ratios were optimized to remove tetracycline (TET) from synthetic wastewater. To enhance the tetracycline removal performance, the effect of microalgae-bacterial co-culture ratio, maximum TET concentration, effective inoculum amount, growth temperature and pH were studied. The optimized ratio 1:2 of Desmodesmus sp.: K. pneumoniae showed the optimal removal percentage at the temperature of 25 °C, pH 7 and 10% inoculum amount; and the removal of TET was recorded as 95%. Moreover, this study explored the Desmodesmus sp.: K. pneumoniae (1:2) nutrient (COD, NH4+ and PO43-) exchange relationship and their interaction of TET removal to better understand their fundamental mechanism. According to the results of this study, Desmodesmus sp.: K. pneumoniae co-culture could be a green option for bio-removal of tetracycline from wastewater.

Successful bio-electrochemical treatment of nitrogenous mariculture wastewater by enhancing nitrogen removal via synergy of algae and cathodic photo-electro-catalysis.

Systems with catalytic cathode in microbial fuel cell can achieve high treatment efficiency enhanced by the cathode. Such bio-electrochemical systems have potential applications in treating high-salinity nitrogenous mariculture wastewater. For sustainable development of the mariculture industry, enhancing inorganic nitrogen removal is of vital importance due to the low carbon to nitrogen (C/N) ratio of wastewater and strict discharge standard. Herein, simulated mariculture wastewater (high salinity, low COD/N ratio of 0.5-1.0) was successfully treated in an integrated self-biased bio-electrochemical system, with catalyst (TiO2/Co-WO3/SiC) on the cathode and natural-grown algae in the cathode chamber. Satisfactory nitrogen removal (94.05% NH4+-N and 77.35% inorganic nitrogen) and favorable 76.66% removal of organics (UV254) were both achieved, with visible light illumination. The NH4+-N in the effluent was below 2 mg L-1. The synergy of bacteria, algae and cathode, promoted pollutant removal, and made the system sustainable and efficient in treating mariculture wastewater.

Investigating the potentiality of Scenedesmus obliquus and Acinetobacter pittii partnership system and their effects on nutrients removal from synthetic domestic wastewater.

A lab-scale study of Scenedesmus obliquus: Acinetobacter pittii (S. obliquus: A. pitti) partnership cultured in synthetic domestic wastewater was conducted to evaluate the partnership performance for growth and removal of nutrients from wastewater. To draw out the functional dependencies of this partnership measured the ammonia-nitrogen (NH4+-N), ortho-phosphate (PO43--P), soluble total phosphorus (TP), chemical oxygen demand (COD) and have got the nutrient removal rate of 85.90%, 91.50%, 73.75% and 100% respectively. The results showed that their optimized partnership ratio is 2:1 for S. obliquus: A. pitti and, CO2 & O2 exchanges in between was the more crucial parameters to shifting the best nutrient removals performance and promoted biomass quantity.

Microarray Analysis of Gene Expression Changes in Neuroplastin 65-Knockout Mice: Implications for Abnormal Cognition and Emotional Disorders / 神经科学通报·英文版

Neuroplastin 65 (Np65) is an immunoglobulin superfamily cell adhesion molecule involved in synaptic formation and plasticity. Our recent study showed that Np65-knockout (KO) mice exhibit abnormal cognition and emotional disorders. However, the underlying mechanisms remain unclear. In this study, we found 588 differentially-expressed genes in Np65-KO mice by microarray analysis. RT-PCR analysis also revealed the altered expression of genes associated with development and synaptic structure, such as Cdh1, Htr3a, and Kcnj9. In addition, the expression of Wnt-3, a Wnt protein involved in development, was decreased in Np65-KO mice as evidenced by western blotting. Surprisingly, MRI and DAPI staining showed a significant reduction in the lateral ventricular volume of Np65-KO mice. Together, these findings suggest that ablation of Np65 influences gene expression, which may contribute to abnormal brain development. These results provide clues to the mechanisms underlying the altered brain functions of Np65-deficient mice.

Effect of Paroxetine Combined with Low Dose of Olanzapine on Sleep Process and Architecture of Depression Patients with Insomnia / 中国药房

OBJECTIVE:To study the effect of paroxetine combined with low dose of olanzapine on sleep process and architec-ture of depression patients with insomnia. METHODS:84 depression patients with insomnia were randomly divided into control group and observation group. Control group was given 20 mg Paroxetine tablet,once every morning;observation group was addi-tionally given 2.5 mg Olanzapine tablet,once before going to bed. Sleep quality [Pittsburgh Sleep Quality Index(PSQI)],depres-sion scores [Hamilton Depression Scale (HAMD)],sleep process [sleep latency (SL),awakening times (AT),the actual total sleep time (TST),sleep efficiency (SE),rapid eye movement (REM) sleep latency (RL)] and sleep architecture [sleep stage 1 (S1),2(S2),3(S3)and the proportion of REM to sleep] in 2 groups before and 3,6 months after treatment and the incidence of adverse reactions(ADR)were observed. RESULTS:After treatment,PSQI and HAMD scores in 2 groups were significantly lower than before,and gradually decreased by time,and observation group was lower than control group;TST in observation group was significantly higher than before and control group,S1 in observation group was significantly lower than before,SE,S3 and REM in 2 groups were significantly higher than before,and observation group was higher than control group,SL,AT,RL and S2 were significantly lower than before,and observation group was lower than control group,the differences were statistically significant (P<0.05). There were no obvious ADR in 2 groups. CONCLUSIONS:Paroxetine combined with low dose of olanzapine can sig-nificantly relieve depression,optimize sleep process and sleep architecture,then impove sleep quality.

Correlation between C-JUN activation domain binding protein 1 and P27~(kip1) in ovarian cancer cell HO-8910 / 基础医学与临床

Objective To investigate the expression and relationship of Jab1 and P27kip1 in ovarian cancer cell HO-8910. Methods Cells were treated with serum starvation and release.The expression and distribution of Jab1 and P27kip1 were detected by western blot and subcellular fractionation.HO-8910 cells were transfected in vitro with pcDNA3.1-MYC-Jab1.Western blot as well as subcellular fractionation was used to detect the expression and localization of P27kip1.Results The growth of HO-8910 cells was blocked by serum starvation.P27kip1 increased while Jab1 decreased.The reverse changes were found after serum release.P27kip1 and Jab1 could form compound in HO-8910 cells detected by immunoprecipitation.48h after transfected by pcDNA3.1-MYC-Jab1,the expression of P27kip1 decreased and the distribution of P27kip1 translocated from nucleus into cytoplasma in HO-8910.Conclusion Jab1 may control the location and expression of P27kip1 through integrating with P27kip1,and participate in regulating the growth of ovarian cancer cells through interfering with the function of P27kip1.
