Objective To evaluate the efficacy and safety of methyldopa and labetalol in treating hypertension disorders in pregnancy.Methods Databases of MedLine,Cochrane Library,EMbase,CNKI,Wanfang,and VIP were searched for published randomized controlled trials (RCTs) on hypertension disorders in pregnancy with methyldopa as treatment group and labetalol as control group.Meta-analysis was conducted by RevMan 5.3 software.Results A total of 10 RCTs involving 1285 patients were included.Rates of severe hypertension in treatment group and control group were 6.62％ and 12.21％,respectively.Rates of proteinuria were 15.57％ and 8.52％,rates of adverse drug reaction were 21.82％ and 25.63％,rates of fetal/infant death were 4.19％ and 2.84％.The results of Meta-analysis revealed that there were no significant differences in the above parameters between treatment and control groups.However,plasma viscosity was significantly lower in treatment group compared with that in control group (RR =0.77,95％ CI =0.64-0.90,P ＜ 0.001).Conclusion Methyldopa and labetalol are equally effective and safe in treating hypertension disorders in pregnancy,while methyldopa is more effective in reducing plasma viscosity.

19 cinnamamide/ester-triazole compounds were designed, synthesized and evaluated for their anti-Alzheimer's disease (AD) activity. Among them, compound 4f displayed excellent anti-β-amyloid protein (Aβ)-mediated cytotoxicity (EC₅₀ = 2.03 ± 2.45 μmol·L^-1) in APPswe cells and acetylcholinesterase inhibiton (IC₅₀ = 4.88 ± 4.70 μmol·L^-1). Further study indicated that, at dosages of (1, 5 and 25 mg·kg^-1), compound 4f was effective in improving spatial learning and memory deficits in Aβ_1-42-impaired mice, which was achieved by promoting the nonamyloidogenic signaling and inhibiting the amyloidogenic pathway, along with the suppression of Aβ-induced Tau phosphorylation. All animal experiments in this study were approved by the Experimental Animal Care and Use Committee of the Institute of Medicinal Biotechnology (IMB-20220908D701). In conclusion, compound 4f holds promise as a lead candidate for AD treatment, and the present study lays the foundation for its subsequent development.

Background: Feline mammary carcinoma is the third most common cancer that affects female cats. Objectives: The purpose of this study was to screen differential serum proteins in feline and clarify the relationship between them and the occurrence of feline mammary carcinoma. Methods: Chinese pastoral cats were used as experimental animals. Six serum samples from cats with mammary carcinoma (group T) and six serum samples from healthy cats (group C) were selected. Differential protein analysis was performed using a Label-free technique, while parallel reaction monitoring (PRM) was performed to verify the screened differential proteins. Results: A total of 82 differential proteins were detected between group T and group C, of which 55 proteins were down regulated and 27 proteins were up regulated. Apolipoprotein A-I, Apolipoprotein A-II (ApoA-II), Apolipoprotein B (ApoB), Apolipoprotein C-III (ApoC-III), coagulation factor V, coagulation factor X, C1q, albumen (ALB) were all associated with the occurrence of feline mammary carcinoma. Differential proteins were involved in a total of 40 signaling pathways, among which the metabolic pathways associated with feline mammary carcinoma were the complement and coagulation cascade and cholesterol metabolism. According to the Label-free results, ApoB, ApoC-III, ApoA-II, FN1, an uncharacterized protein, and ALB were selected for PRM target verification. The results were consistent with the trend of the label-free. Conclusions This experimen is the first to confirm ApoA-II and ApoB maybe new feline mammary carcinoma biomarkers and to analyze their mechanisms in the development of such carcinoma in feline.

Aim To observe whether matrix metallo-proteinase-14 ( MMP-14) and tissue matrix metallopro-teinase inhibitor-4 ( TIMP-4) were involved in the car-diac-protection of mitochondrial aldehyde dehydrogen-ase 2 ( ALDH2) against high glucose induced rat pri-mary cardiomyocyte injury. Methods Rat primary cardiomyocytes were cultured. The cardiomyocyte via-bility was detected by MTT assay at different concentra-tion of glucose at different time point. After established high glucose-induced cardiomyocytes injury model, cardiomyocytes were randomly divided into 4 groups:normal control group ( NG, glucose at 5.5 mmol· L-1) , NG + Alda-1 group ( Alda-1 at 20 μmol·L-1) , high glucose group ( HG, glucose at 30 mmol·L-1) and HG+Alda-1 group. The cell viability at 48 h and oxidative stress level were detected by MTT and DHE staining methods. The protein expressions of ALDH2, MMP-14 and TIMP-4 were determined by Western blot. Results The cardiomyocytes injury model was established according to the cell activity result. Com-pared with NG group, the cell viability, the protein ex-pressions of ALDH2, MMP-14, the ratio of MMP-14/TIMP-4 were decreased, TIMP-4 protein expression and the level of oxidative stress were increased in HG group. Compared with HG group, in HG + Alda-1 group, the cell viability, the protein expressions of AL-DH2, MMP-14, the ratio of MMP-14/TIMP-4 were in-creased, the levels of oxidative stress and TIMP-4 pro-tein expression were decreased. Conclusion Activa-tion of mitochondrial ALDH2 may relieve high glucose induced cardiomyocytes injury. The protective effect was likely related to the inhibition of oxidative damage, down-regulation of MMP-14 and up-regulation of TIMP-4 proteins.

Objective To observe the clinical efficacy of self-prescribed Guchong Decoction combined with Ferroids for the treatment of iron deficiency anemia (IDA)patients with unconsolidation of thoroughfare and conception vessels. Methods A total of 70 IDA patients with unconsolidation of thoroughfare and conception vessels were randomized into treatment group and control group,35 cases in each group. The control group was given oral use of Ferroids, and the treatment group was treated with self-prescribed Guchong Decoction combined with Ferroids. One month constituted a treatment course,and both groups were treated for 2 courses. Before and after treatment,we compared the parameters of blood routine test for red blood cells(RBC),hemoglobin (HGB), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), MCH concentration (MCHC),white blood cells(WBC)and platelets,as well as reticulocytes(Ret)and iron metabolism indexes including serum iron(SI),serum ferritin(SF),and total iron-binding capacity(TIBC). The adverse reaction was monitored during the treatment. After treatment,both western medicine clinical efficacy and traditional Chinese medicine (TCM)syndrome clinical efficacy of the two groups were evaluated. A 3-month follow-up was carried out after treatment to evaluate the recurrence rate. Results(1)Drop-out occurred in one case from the treatment group and in 2 cases from the control group because of short-term medication suspension.(2)After treatment for 2 months, western medicine clinical cure rate of the treatment group was 82.4％ and that of the control group was 60.6％, and TCM syndrome clinical cure rate of the treatment group was 94.1％ and that of the control group was 51.5％,the difference being significant(P < 0.05 or P < 0.01).(3)The levels of RBC,HGB,Ret, MCV, MCH, MCHC, and WBC of the two groups were obviously increased after treatment (P < 0.01), and PLT level was markedly decreased (P < 0.01)as compared with those before treatment,but the inter-group differences after treatment were insignificant (P > 0.05). (4)After treatment,iron metabolism indexes of SF and SI of the two groups were significantly increased (P < 0.01), and TIBC of the treatment group was significantly decreased (P < 0.01). The treatment group had stronger effect on increasing SF and SI and on decreasing TIBC than the control group (P < 0.05 or P < 0.01). (5)The incidence of adverse reaction and the recurrence rate in the treatment group were lower than those of the control group,the difference being significant (P< 0.01). Conclusion Guchong Decoction combined with Ferroids is effective for the treatment of IDA with unconsolidation of thoroughfare and conception vessels through relieving symptoms rapidly, reducing gastrointestinal adverse reaction,and decreasing recurrent rate.

Objective To screen the optimal regimen of Chinese medicine combined with hormones for the treatment of premature ovarian failure(POF)using network meta-analysis and to provide an evidence-based basis for the clinical treatment of POF.Methods The randomized controlled trials(RCTs)of Chinese medicine combined with hormones in the treatment of POF were retrieved from thhe domestic and oversea databases of CNKI,VIP,Wanfang,CBM,PubMed,Cochrane,Embase,and Web of Science.The quality of the literature was assessed using the tools for analysis of bias recommended by Cochrane Reviewer's Handbook and by Jadad scale scores.Rstudio and StataSE 15.1 statistical software were used to perform network meta-analysis and graphical presentation of the data.Results A total of 50 RCTs were included,covering 8 intervention methods.The overall risk of bias of the included studies was low,but the quality of the literature was generally low.The results of network meta-analysis showed that,in terms of the effective rate,the intervetion of 7 various Chinese medicines combined with hormone was superior to the conventional treatment(hormone replacement therapy,HRT)in the control group,and Nuangong Qiwei Powder+HRT was superior to the remaining 6 kinds of Chinese medicines combined with HRT;with reference to the values of the surface under the cumulative ranking curve(SUCRA),the efficiencies of the effective rate of the 8 intervention methods in descending order were Nuangong Qiwei Powder+ HRT(SUCRA=81.2),Zishen Yutai Pills + HRT(SUCRA=80.0),modified Zuogui Pills + HRT(SUCRA= 66.1),Ankun Zhongzi Pills + HRT(SUCRA=49.6),Kuntai Capsules + HRT(SUCRA=45.2),modified Erxian Decoction + HRT(SUCRA=39.5),Liuwei Dihuang Pills + HRT(SUCRA=37.4)and HRT(SUCRA=1.0).In terms of improving serum follicle-stimulating hormone(FSH)levels,modified Zuogui Pills + HRT was superior to the remaining 7 intervention methods;with reference to the values of the SUCRA,the efficiencies of the 8 intervention methods in descending order were modified Zuogui Pills + HRT(SUCRA=97.0),HRT(SUCRA= 77.9),Liuwei Dihuang Pills + HRT(SUCRA=76.6),Kuntai Capsules + HRT(SUCRA=46.5),Nuangong Qiwei Powder+HRT(SUCRA=38.9),Ankun Zhongzi Pills + HRT(SUCRA=29.9),modified Erxian Decoction + HRT(SUCRA=18.1),and Zishen Yutai Pills + HRT(SUCRA=15.1).Conclusion All kinds of Chinese medicines combined with HRT exert stronger effect on improving the primary outcome indicators than HRT alone for the treatment of POF.The intervention with Nuangong Qiwei Powder+HRT exerts the highest probability of the optimal regimen for enhancing the efficiency,and the intervention with Zuogui Pills + HRT exerts the highest probability of the optimal regimen for lowering the serum FSH level.However,due to the low quality of the included studies,more rigorously-designed,large sample-size,and high-quality randomized controlled trials need to be conducted in the future to provide conclusive evidence-based evidence.
