Guided by the concept of quality by design(QbD), this study optimizes the calcination and quenching process of calcined Magnetitum and establishes the XRD characteristic spectra of calcined Magnetitum, providing a scientific basis for the formulation of quality standards. Based on the processing methods and quality requirements of Magnetitum in the Chinese Pharmacopoeia, the critical process parameters(CPPs) identified were calcination temperature, calcination time, particle size, laying thickness, and the number of vinegar quenching cycles. The critical quality attributes(CQAs) included Fe mass fraction, Fe~(2+) dissolution, and surface color. The weight coefficients were determined by combining Analytic Hierarchy Process(AHP) and the criteria importance though intercrieria correlation(CRITIC) method, and the calcination process was optimized using orthogonal experimentation. Surface color was selected as a CQA, and based on the principle of color value, the surface color of calcined Magnetitum was objectively quantified. The vinegar quenching process was then optimized to determine the best processing conditions. X-ray diffraction(XRD) was used to establish the characteristic spectra of calcined Magnetitum, and methods such as similarity evaluation, cluster analysis, and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to evaluate the quality of the spectra. The optimized calcined Magnetitum preparation process was found to be calcination at 750 ℃ for 1 h, with a laying thickness of 4 cm, a particle size of 0.4-0.8 cm, and one vinegar quenching cycle(Magnetitum-vinegar ratio 10∶3), which was stable and feasible. The XRD characteristic spectra analysis method, featuring 9 common peaks as fingerprint information, was established. The average correlation coefficient ranged from 0.839 5-0.988 1, and the average angle cosine ranged from 0.914 4 to 0.995 6, indicating good similarity. Cluster analysis results showed that Magnetitum and calcined Magnetitum could be grouped together, with similar compositions. OPLS-DA discriminant analysis identified three key characteristic peaks, with Fe_2O_3 being the distinguishing component between the two. The final optimized processing method is stable and feasible, and the XRD characteristic spectra of calcined Magnetitum was initially established, providing a reference for subsequent quality control and the formulation of quality standards for calcined Magnetitum.

ObjectiveTo observe the effects of Yuejuwan in the treatment of psychological and heart diseases (PHD) and explore its mechanism. MethodThirty 6-week-old healthy male SPF AopE-/- mice and 10 homologous C57BL/6J mice were selected for the experiment. The 30 AopE-/- mice were divided into a model group, low-dose (7.58 g·kg-1·d-1) and high-dose (30.32 g·kg-1·d-1) Yuejuwan groups, with 10 mice in each group, and 10 C57BL/6J mice were assigned to the blank control group. Intragastrical administration lasted 12 weeks. During feeding, the PHD model was induced by chronic unpredictable mild stress (CUMS) combined with high-fat diet in mice. After intragastric administration, the behavioral results [open field test (OFT) and sucrose preference test (SPT)] of mice in each group, the content of aspartic transaminase (AST), alanine aminotransferase (ALT), 5-hydroxytryptamine (5-HT), noradrenaline (NE), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), and triglyceride (TG) in serum of mice detected by the automatic biochemical analyzer, the oil red O staining and HE staining of aorta and liver and Masson staining of myocardial tissues were used for model evaluation. Finally, liver TMT-labeled quantitative proteomics was used to explore the mechanism of action. ResultThe model mice showed obvious manifestations of depression, anxiety, loss of interest, and despair, manifest lipid deposition in the aorta and liver by pathological observation, and increased myocardial fibrosis in myocardial tissues. After intragastric administration of Yuejuwan, the above symptoms and indexes of the PHD model mice were improved. Compared with the blank control group, the model group showed decreased standing times, cumulative time in the central area, total moving distance, moving speed, and sucrose preference at week 12 (P<0.01). Compared with the model group, the Yuejuwan groups showed decreased indexes mentioned above (P<0.01). After sample collection, AST, ALT, and TG levels in the model group were higher (P<0.01) and the levels of 5-HT, NE, and HDL-C were lower than those in the blank control group (P<0.01). The results of liver TMT labeled quantitative proteomics suggested that the PHD model mainly caused the changes in protein expression levels such as ApoE, UGT1A5, and FASN in mice,involving acetyl CoA metabolism,response to bacteria,cellular amino acid catabolism, and other processes,which were related to the abnormal metabolic function of the liver. The efficacy of Yuejuwan against PHD was achieved mainly through the regulation of high mobility group nucleosomal-binding domain 2 (HMGN2), CALD1, and Mup7 protein expression levels and correcting the biological processes and abnormal pathways related to the pathogenesis of PHD,including muscle contraction,tight junction pathway,myocardial contraction pathway,and focal adhesion pathway. ConclusionCUMS combined with high-fat diet is reasonable in the induction of the PHD model in AopE-/- mice. Yuejuwan can correct the depression and anxiety conditions of PHD model mice,reduce the aortic plaque, and recover the abnormal blood lipid and liver function levels. Furthermore, Yuejuwan can correct abnormal biological processes and pathways of PHD model mice. The differential proteins screened throughout the experiment and the involved physiological and pathological changes are the focus of the next experiment.

ObjectiveTo compare the therapeutic effects of oral Chinese medicines (including Chinese patent medicines) on coronary artery disease (CAD) by the Bayesian network Meta-analysis. MethodThe randomized controlled trials of treating CAD with oral Chinese medicines were retrieved from the China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, PubMed, Web of Science, Embase, and Cochrane Library from the inception to December 1, 2022. The Cochrane risk of bias assessment tool was used to evaluate the quality of the included articles. The direct meta-analysis was performed to compare the performance of oral Chinese medicines alone and in combination with Western medicine in the treatment of CAD in terms of intima-media thickness (IMT), vascular endothelial function, plaque score, hypersensitive C-reactive protein (hs-CRP), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and total response rate. Furthermore, the Bayesian network Meta-analysis was performed to compare the therapeutic effects of different Chinese medicines. ResultA total of 41 articles were included. The direct meta-analysis results showed that Chinese medicines combined with Western medicine outperformed Western medicine alone in recovering all the indicators of CAD. The Bayesian network meta-analysis yielded the following results. In terms of the total response rate, modified Huangqi Guizhi Wuwutang and Sanqi Huayu pills had obvious advantages over other Chinese medicines. In terms of IMT and plaque score, Xiaoban Huazhuo decoction, Yiqi Tongluo formula, Ruangan Jiangzhi capsules, and Guanxin Shutong capsules had obvious advantages over other Chinese medicines. In terms of blood lipid indicators, Shenqi Roumai mixture, Ruangan Jiangzhi capsules, Xiaoban Huazhuo decoction, Qiwei Sanxiong decoction, and Sanqi Huayu pills were superior to other Chinese medicines. The Chinese medicines above mainly had the functions of activating blood, resolving stasis, resolving phlegm, and dredging vessels. ConclusionThe combination of oral Chinese medicines and Western medicine is effective in treating CAD. Clinicians can use the drugs targeting abnormal indicators according to the results of this Bayesian network meta-analysis combined with the actual situation of patients to achieve better therapeutic effects.

OBJECTIVE:
Apios americana, a plant used as a staple ingredient of native American diets, has various properties, including anti-cancer, anti-hyperglycemic, hypotensive, and anti-inflammatory activity. In Japan, Apios is used as a post-natal medication. After parturition, women undergo a period of recovery as they return to pre-pregnancy conditions. However, few health products that aid post-partum recovery are on the market. We explored whether Apios can accelerate the post-partum recovery process, in particular the involution of the uterus.
METHODS:
Female rats kept in individual cages were mated with two male rats, with the exception of the control group (female rats without mating, on basal diet; n=6). After delivery, rats were divided into five groups based on their diet: basal diet (model; n=6); basal diet+oral intake at 5.4 g/kg of Chanfukang granules (a Chinese patent medicine preparation for post-partum lochia) (positive; n=6); basal diet containing 10% Apios powder (low; n=6); basal diet containing 20% Apios powder (medium; n=6); basal diet containing 40% Apios powder (high; n=6). Five days later, uteri and spleens were weighed. Uterus and spleen indices for each rat were calculated by dividing visceral weight by the total weight. Hormone and cytokine concentrations were measured using enzyme-linked immunosorbent assay (ELISA). Histological analysis of uteri was completed using hematoxylin and eosin (H&E) staining. Expression of matrix metalloproteinases and inhibitors in uteri was measured by western blotting.
RESULTS:
Our results showed that Apios treatment reduced the post-partum uterus index and regulated the hormone concentrations. Moreover, we found that the process of uterine involution was accelerated, based on morphological changes in the uterus. In addition, our results indicated that Apios alleviated the inflammatory response induced by the involution process. Transforming growth factor β was also found to be regulated by Apios. There were significant downregulation of matrix metalloproteinases and upregulation of their inhibitors by Apios, which suggested that Apios increased the rate of the collagen clearance process.
CONCLUSIONS
These results, based on experimental observations at the molecular and protein levels, verified our hypothesis that Apios can improve uterine involution, and demonstrated the potential application of Apios in post-partum care.

OBJECTIVETo investigate the risk factors for the development of congenital anal atresia in neonates.
METHODSA total of 70 neonates who were admitted to 17 hospitals in Foshan, China from January 2011 to December 2014 were enrolled as case group, and another 70 neonates who were hospitalized during the same period and had no anal atresia or other severe deformities were enrolled as control group. Univariate and multivariate logistic regression analyses were used to investigate the risk factors for the development of congenital anal atresia.
RESULTSThe univariate analysis revealed that the age of mothers, presence of oral administration of folic acid, infection during early pregnancy, and polyhydramnios, and sex of neonates showed significant differences between the case and control groups (P<0.05). The multivariate logistic regression analysis revealed that infection during early pregnancy (OR=18.776) and male neonates (OR=9.304) were risk factors for congenital anal atresia, and oral administration of folic acid during early pregnancy was the protective factor (OR=0.086).
CONCLUSIONSInfection during early pregnancy is the risk factor for congenital anal atresia, and male neonates are more likely to develop congenital anal atresia than female neonates. Supplementation of folic acid during early pregnancy can reduce the risk of congenital anal atresia.

Objective To study the inhibition effect of miR-106a inhibitor on tumor growth of ovarian cancer xenografts mice. Methods BALB/c mice were selected as experimental animals, ovarian cancer SKOV-3 cells transfected with miR-106a inhibitor and its negative control were inoculated subcutaneously, intratumoral injection of miR-106a inhibitor and its negative control were continued after tumor formation, and they were enrolled as treatment group and model group, respectively. Tumor volume and weight as well as Ki-67 and programmed cell death 4 (PDCD4) expression were determined; miR-106a inhibitor and its negative control as well as miR-106a mimic and its negative control were transfected into SKOV-3 cells, and expression of PDCD4 in cells was determined. Results Tumor tissue volume and weight as well as mRNA expression and protein expression of Ki-67 in treatment group were significantly lower than those in the model group while mRNA expression and protein expression of PDCD4 were significantly higher than those in the model group; transfection of miR-106a mimic could decrease mRNA expression and protein expression of PDCD4 in SKOV-3 cells, and transfection of miR-106a inhibitor could increase mRNA expression and protein expression of PDCD4 in SKOV-3 cells. Conclusions Transfection of miR-106a inhibitor can inhibit the growth of tumor in ovarian cancer xenografts mice through increasing the expression of PDCD4.

BACKGROUNDInterleukin (IL)-27 has been reported to have anti-proliferate and anti-angiogenic activities on cancer cells. However, the involvement of IL-27 in malignant pleural effusion (MPE) remains unknown. Thus, in this research, we compared the immune functions of IL-27, interferon (IFN)-γ, and IL-17 on lung cancer cells and revealed the regulatory mechanism of IL-27 in MPE.
METHODSThe distribution of IL-27 in both MPE and blood was evaluated by enzyme-linked immunosorbent assay and flow cytometry. The expressions of cytokine receptors and the levels of the phosphorylated signal transducer and activator of transcription (STAT) signalings were detected by flow cytometry. As well as the effects of proliferation, apoptosis, migration, and adherent activity of IL-27, IFN-γ, and IL-17 on lung cancer cells were also explored.
RESULTSThe expression of IL-27 was increased in MPE when compared with blood (147.3 ± 25.1 pg/ml vs. 100.3 ± 13.9 pg/ml, P = 0.04). IL-27 was noted to suppress both proliferation (18.33 ± 0.21 vs. 27.77 ± 0.88, P = 0.0005) and migration (1.82 ± 0.44 vs. 3.13 ± 0.07, P = 0.04) of A549 cells, but obviously promoted apoptosis of A549 cells (9.47 ± 1.14 vs. 4.96 ± 0.17, P = 0.02) by activating STAT1 signaling. Interestingly, IL-27 played totally opposite effects on A549 cells by activating STAT3 pathway. Moreover, IL-27 exerted different intercellular adherent activities of A549 cells to pleural mesothelial cell monolayer by activating different STAT signalings.
CONCLUSIONSIL-27 might exert an important immune regulation on lung cancer cells in human pleural malignant environment.
