RESUMEN
OBJECTIVE: Increasing researches supported that intravenous ketamine/esketamine during the perioperative period of cesarean section could prevent postpartum depression(PPD). With the effective rate ranging from 87.2 % to 95.5 % in PPD, ketamine/esketamine's responsiveness was individualized. To optimize ketamine dose/form based on puerpera prenatal characteristics, reducing adverse events and improving the total efficacy rate, prediction models were developed to predict ketamine/esketamine's efficacy. METHOD: Based on two randomized controlled trials, 12 prenatal features of 507 women administered the ketamine/esketamine intervention were collected. Traditional logistics regression, SVM, random forest, KNN and XGBoost prediction models were established with prenatal features and dosage regimen as predictors. RESULTS: According to the logistic regression model (ain = 0.10, aout = 0.15, area under the receiver operating characteristic curve, AUC = 0.728), prenatal Edinburgh Postnatal Depression Scale (EPDS) score ≥ 10, thoughts of self-injury and bad mood during pregnancy were associated with poorer ketamine efficacy in PPD prevention, whilst a high dose of esketamine (0.25 mg/kg loading dose+2 mg/kg PCIA) was the most effective dosage regimen and esketamine was more recommended rather than ketamine in PPD. The AUCvalidation set of KNN and XGBoost model were 0.815 and 0.651, respectively. CONCLUSION: Logistic regression and machine learning algorithm, especially the KNN model, could predict the effectiveness of ketamine/esketamine iv. during the course of cesarean section for PPD prevention. An individualized preventative strategy could be developed after entering puerpera clinical features into the model, possessing great clinical practice value in reducing PPD incidence.

This study aims to examine (i) the effect of diluent types (lactose monohydrate, corn starch, and microcrystalline cellulose) and granulation liquids (20% polyvinylpyrrolidone K30, 65% alcohol, and dispersion containing 40% model drug- Pithecellobium clypearia Benth extracted powder) on granule properties and tablet quality for high shear wet granulation and tableting (HSWG-T) and, more importantly, (ii) the attribute transmission in the process. In general, the impact of diluents on granule properties and tablet quality was more dominant than that of granulation liquids. Attribute transmission patterns were revealed as follows. The granules' ISO. Roundness and density correlated with raw material (i.e., model drug, diluent, and/or granulation liquid) properties such as density and viscosity. The granules' compressibility parameter a correlated with the granules' Span, and parameter y0 correlated with the granules' flowability and friability. Compactibility parameters ka and kb correlated mainly with granules' flowability and density, and parameter b correlated significantly and positively with tablet tensile strength. The compressibility correlated negatively with tablet solid fraction (SF) and friability, while the compactibility correlated positively with tablet disintegration time. Moreover, the rearrangement and elasticity of granules correlated positively with SF and friability, respectively. Overall, this study provides some guides for achieving high-quality tablets via HSWG-T.

A molecularly imprinted photoelectrochemical sensor with high sensitivity and stable structure was constructed and applied to detect thiamethoxam pesticide. ZnO/Bi2O3/Bi2S3 heterojunction photoelectric material was formed on the fluorine-doped tin oxide (FTO) electrode by seed layer growth, drip coating, and in situ ion exchange. A chitosan-imprinted polymer membrane was prepared using chitosan as the functional monomer, glutaraldehyde as the cross-linking agent, and thiamethoxam as the template molecule. The photoelectric material was characterized by X-ray diffraction, scanning electron microscopy, and energy dispersive x-ray spectroscopy analyses. The electron transfer mechanism of Z-type heterojunction was verified by ultraviolet-visible curve and Mott-Schottky curve. When thiamethoxam was re-adsorbed on the imprinted membrane, the current recorded at 0 V (vs. Ag/AgCl) was reduced because the thiamethoxam molecule blocked the electron transfer. The molecularly imprinted sensor exhibited a linear relationship to thiamethoxam concentration in the range from 7.0 × 10-13 mol/L to 7.0 × 10-10 mol/L and the detection limit was 3.32 × 10-13 mol/L, which is lower than the values reported by other detection methods. Most pesticides, such as propoxur and isoprocarband carbaryl, do not interfere with the determination. The sensor also showed good practicability and suitability for the determination of trace thiamethoxam in environmental water and soil leaching solutions, with a recovery of 99.6-102.1% (RSD < 3.74%). A novel molecularly imprinted photoelectrochemical (MI-PEC) sensor with high sensitivity and selectivity for the determination of thiamethoxam (TMX) was developed. A Z-type heterojunction ZnO/Bi2O3/Bi2S3 photoelectric material was synthesized for the first time. The MI-PEC sensor was prepared with ZnO/Bi2O3/Bi2S3 as the sensitive material and MI membrane as the recognition element. The sensor exhibits an extremely sensitive response to thiamethoxam with a detection limit of 3.32 × 10-13 mol/L due to the excellent photoelectrochemical properties of ZnO/Bi2O3/Bi2S3.

Background: The dementia and affective disorders are common non-motor features in patients with essential tremor (ET). However, the relationship of ET with cognitive impairments and affective disorders remains controversial. This meta-analysis aimed to analyze the association of ET with dementia and affective disorders. Methods: Original studies published from January 1999 to October 2019 were systematically searched from the database of Medline (OvidSP), EMBASE (OvidSP), and the Cochrane Central Register of Controlled Trials. Pooled standard mean difference (SMD, random effect model), odds ratios (ORs), relative risk (RR), and 95% CI were calculated. Results: Compared with the Non-ET group, patients with ET had significantly lower Mini-Mental State Examination (MMSE) score (SMD, -1.16; 95% CI, -1.75 to -0.58; p = 0.0001) and had significantly higher depressive and anxiety symptoms scale score (SMD, 0.55; 95% CI, 0.22-0.87; p = 0.0009). The OR for dementia and affective disorders in individuals with ET compared with individuals without ET was 2.49 (95% CI, 2.17-2.85, p < 0.00001). While there was no significant difference in Montreal Cognitive Assessment (MoCA) score between ET and Non-ET groups (SMD, -0.52; 95% CI, -0.16 to 0.13; p = 0.23), there was a significant difference in the risk of mortality between ET and Non-ET groups (RR = 4.69, 95% CI, 2.18-10.07). Conclusion: The non-motor symptoms should not be neglected among patients with ET. However, the causal relationship between ET and dementia, depression, and anxiety is unclear.
RESUMEN
BACKGROUND: The Caoguo-4 decoction, a classical Mongolian medicine formula, is widely used to treat spleen deficiency diarrhea (SDD) in Mongolian for decades. Previously, the Caoguo-4 decoction volatile oil has been confirmed to be effective in ameliorating symptoms of spleen deficiency diarrhea in an animal model. However, the underlying mechanism of the Caoguo-4 decoction volatile oil is yet to be established. The aim of the current study was to investigate the antidiarrheal effects and mechanism of the Caoguo-4 decoction volatile oil. METHOD: Wistar rats were randomly divided into 5 groups of 10 animals including control, model, positive, Caoguo-4 decoction, and Caoguo-4 decoction volatile oil groups (10 rats in each group). All the rats, besides those in the control group, were induced to develop SDD by a bitter-cold purgation method with Xiaochengqi decoction. The antidiarrheal effect of Caoguo-4 decoction volatile oil was evaluated by pathological section, serum D-xylose and AMS content, plasma MTL content, and gut microbiota analysis via 16S rRNA sequencing. RESULTS: The results showed that the developed SDD rat model (model group) had decreased food intake, increased weight loss, soft stool, and bad hair color. When compared with the control group, serum was significantly reduced serum D-xylose and AML but increased MTL levels in the model group (p < 0.05). However, after treatment with either the Caoguo-4 decoction (the decoction group) or Smecta (the positive group) or volatile oil from the Caoguo-4 decoction (the volatile oil group), a significant increase in the serum D-xylose levels was observed. Additionally, AML levels significantly increased in the positive and volatile oil groups, and MTL levels significantly decreased in the decoction and volatile oil groups, when compared with the model group (p < 0.05). The pathological changes of the intestinal mucosa showed that the structure of the epithelium in the villi of the small intestine was affected, deformed, and incomplete in the model group when compared with the control group. However, either the decoction group or the volatile oil group recovered the villous morphology. The results of OTU analysis and alpha diversity analysis of intestinal bacteria showed that the intestinal microbiota of the SDD model rats showed an obvious decrease in richness and diversity of intestinal microbiota. But the intervention treatment of decoction and volatile oil could significantly recover the richness and diversity of intestinal microbiota. CONCLUSION: The intestinal microbiota destroyed in SDD modelling could be significantly improved by the Caoguo-4 decoction volatile oils, which provides reference for clinical medication.

ETHNOPHARMACOLOGICAL RELEVANCE: Slow transit constipation (STC) is a common gastrointestinal disorder seriously impacting patients' quality of life. At present, although conventional chemical drugs effectively control STC symptoms in the short term, the long-term effects are poor, and the side effects are significant. In this regard, traditional Chinese medicine (TCM) offers an opportunity for STC treatment. Many pharmacological and clinical studies have confirmed this efficacy of TCM with multiple targets and mechanisms. AIM OF THE STUDY: This review attempted to summarize the characteristics of TCM (compound prescriptions, single Chinese herbs, and active ingredients) for STC treatment and discussed their efficacy based on analyzing the pathogenesis of STC. MATERIALS AND METHODS: The information was acquired from different databases, including PubMed, Web of Science, China National Knowledge Infrastructure, and Wanfang databases. We then focused on the recent research progress in STC treatment by TCM. Finally, the future challenges and trends are proposed. RESULTS: TCM has good clinical efficacy in the treatment of STC with multi-mechanisms. Based on the theory of syndrome differentiation, five kinds of dialectical treatment for STC by compound TCM prescriptions were introduced, namely: Nourishing Yin and moistening the intestines; Promoting blood circulation and removing blood stasis; Warming Yang and benefiting Qi; Soothing the liver and regulating Qi; and Benefiting Qi and strengthening the spleen. In addition, six single Chinese herbs and eight active ingredients also show good efficacy in STC treatment. CONCLUSIONS: TCM, especially compound prescriptions, has bright prospects in treating STC attributed to its various holistic effects.

BACKGROUND: The Citrus aurantium- (ZhiShi, ZS-) Rhizoma Atractylodis Macrocephalae (BaiZhu, BZ) pairs are often found in herbal formulas for constipation. The volatile oils of ZS and BZ (ZBVO) have good pharmacological activity against constipation, but the mechanism for treatment of slow transit constipation (STC) remains unclear. METHOD: A rat model using diphenoxylate tablets was constructed to investigate if transdermal administration of ZBVO would mediate intestinal microorganisms and fecal metabolites and improve STC symptoms. The regulatory effects of ZBVO at 0.15, 0.30, and 0.60 mL kg-1 d-1 on STC rats were assessed by measuring fecal water content, intestinal propulsion rate, histopathology, expression of gastrointestinal hormones, brain and intestinal peptides, and inflammatory factors. The changes in intestinal flora of STC rats were analyzed by 16S rRNA gene sequencing. Moreover, the untargeted fecal metabolomics analysis was performed by ultraperformance liquid chromatography quadrupole time-of-flight mass spectrometer (UPLC-Q-TOF-MS) technology. RESULTS: The results showed that ZBVO had a modulating effect on STC by increasing the fecal water content and intestinal propulsion rate. Transdermal administration of ZBVO decreased serum levels of interleukin 6 (IL-6) and tumor necrosis factor-α (TNF-α) and increased the levels of gastrin (GAS) and substance P (SP). In addition, ZBVO increased 5-hydroxytryptamine (5-HT) levels and decreased vasoactive intestinal peptide (VIP) levels in colon and hippocampus tissues. The results of intestinal microbiota showed that ZBVO improved the diversity and abundance of intestinal microbiota and changed the community composition by decreasing Romboutsia and increasing Proteobacteria, Allobaculum, and Ruminococcaceae. And the feces metabolomics found that nicotinate and nicotinamide metabolism, purine metabolism, citrate cycle (TCA cycle), pyruvate metabolism, arachidonic acid metabolism, pyrimidine metabolism, and primary bile acid biosynthesis were modulated. CONCLUSION: These findings suggest that ZBVO can alleviate STC symptoms by promoting intestinal peristalsis, increasing fecal water content, regulating gastrointestinal hormone level, reducing the inflammatory response, and regulating brain and intestinal peptides after transdermal administration. And structural changes in the intestinal microbiota are closely related to host metabolism and intestinal microbiota destroyed in STC modeling could be significantly improved by the ZBVO, which provides a reference for the development of aromatic drug macrohealth products.

Due to worldwide abuse of chemical antibiotics and continuous emergence of "superbugs", the harm of bacterial drug resistance to human beings has become more and more serious. Therefore, it is of great significance to look for green antibiotics with a wide range of sources, broad antibacterial spectrum, non-toxicity or low toxicity, environmentally friendliness, diverse active components and low drug resistance. The volatile oil of traditional Chinese medicine is a kind of volatile oily liquid that exists in plants and can be distilled with steam and immiscible with water. Because of its good potential to resist drug-resistant pathogens, it is widely used in food, medicine and other fields. This paper summarized the antibacterial advantages and characteristics of volatile oil of traditional Chinese medicine, and the antibacterial effect and antibacterial mechanism of combined application of volatile oil of traditional Chinese medicine, in order to provide some theoretical basis and study ideas for solving the problem of bacterial drug resistance and developing natural and green antibiotics.

Based on data mining and through the method of network pharmacology, we analyzed the mechanism of high-frequency use of herb pair in the treatment of constipation with aromatic traditional Chinese medicine in this study. Through data mining, aromatic traditional Chinese medicine was obtained for the treatment of constipation and Pericarpium Citri Reticulatae and Aucklandiae Radix herb pair was used as the research object. The volatile oil from Pericarpium Citri Reticulatae and Aucklandiae Radix was extracted by steam distillation, and the chemical compositions of the volatile oil were detected by gas chromatography-mass spectrometry(GC-MS). The targets of volatile oil from Pericarpium Citri Reticulatae and Aucklandiae Radix were searched by PubChem, TCMSP, STITCH and Swiss Target Prediction databases. The targets of constipation were predicted and screened in OMIM, Genecards-Search Resuits and TTD databases. The obtained targets were introduced into Cytoscape 3.7.1 to construct protein-protein interaction(PPI) network diagram for GO and KEGG pathway enrichment analysis by using R language. The network diagram of "component-target-pathway" was constructed according to the results of KEGG enrichment. Discovery Studio 2.5 software was used to verify the molecular docking between the components and the targets. Among them, the most frequently used pair of aromatic traditional Chinese medicine in the treatment of constipation was Pericarpium Citri Reticulatae and Aucklandiae Radix. A total of 33 compounds were detected by GC-MS, and a total of 180 common action targets of Pericarpium Citri Reticulatae and Aucklandiae Radix on volatile oil in the treatment of constipation were predicted. The key targets included CYP19 A1, PPARA, PGR, ACHE, SLC6 A2 and so on. GO enrichment analysis showed that the activities of Pericarpium Citri Reticulatae and Aucklandiae Radix on volatile oil were mainly involved in the biological processes such as circulatory system, blood circulation, and steroid hormone binding. In KEGG enrichment pathway, neuroactive ligand-receptor interaction, endocrine resistance, Ca~(2+) signal pathway and IL-17 signaling pathway showed significant effect on constipation. The results of molecular docking showed that PGR, the target protein related to the treatment of constipation, had a good binding with gamma-linolenic acid, dihydro-alpha-ionone, alpha-eudesmol, caryophyllene oxide and beta-ionone. The results show that by using data mining technology and network pharmacology, it is revealed that the active components of Pericarpium Citri Reticulatae and Aucklandiae volatile oil in high frequency use of aromatic traditional Chinese medicine can be used totreat constipation mainly through CYP19 A1, PPARA, PGR, ACHE, SLC6 A2 and other targets, providing a new idea and method for the further study of aromatic traditional Chinese medicine in the treatment of constipation.

The Aquilaria sinensis (Lour.) Gilg (CX)-Aucklandia costus Falc. (MX) herbal pair is frequently used in traditional Chinese medicine prescriptions for treating depression. The volatile oil from CX and MX has been shown to have good pharmacological activities on the central nervous system, but its curative effect and mechanism in the treatment of depression are unclear. Therefore, the antidepressant effect of the volatile oil from CX-MX (CMVO) was studied in chronic unpredictable mild stress (CUMS) rats. The suppressive effects of CMVO (25, 50, 100 µL/kg) against CUMS-induced depression-like behavior were evaluated using the forced swimming test (FST), open field test (OFT) and sucrose preference test (SPT). The results showed that CMVO exhibited an antidepressant effect, reversed the decreased sugar preference in the SPT and prolongation of immobility time in the FST induced by CUMS, increased the average speed, time to enter the central area, total moving distance, and enhanced the willingness of rats to explore the environment in the OFT. Inhalational administration of CMVO decreased levels of adrenocorticotropic hormone and corticosterone in serum and the expression of corticotropin-releasing hormone mRNA in the hypothalamus, which indicated regulation of over-activation of the hypothalamic-pituitary-adrenal (HPA) axis. In addition, CMVO restored levels of 5-hydroxytryptamine (5-HT), dopamine, norepinephrine and acetylcholine in the hippocampus. The RT-PCR and immunohistochemistry results showed that CMVO up-regulated the expression of 5-HT1A mRNA. This study demonstrated the antidepressant effect of CMVO in CUMS rats, which was possibly mediated via modulation of monoamine and cholinergic neurotransmitters and regulation of the HPA axis.
RESUMEN
OBJECTIVE: To assess the preemptive analgesia effect of catgut implantation in Chengshan (BL 57) area on hemorrhoid operation-induced pain and the security, so as to find a new method for easing post-operative pain of hemorrhoid. METHODS: A total of 120 cases of mixed hemorrhoids patients were randomly divided into the catgut implantation group and medication group (n=60). In implantation group, a piece of catgut was embedded into bilateral BL 57 acupoint area half an hour before surgery. Patients of the medication group were asked to orally take Tramadol Hydrochloride Capsules (100 mg) after the surgery. The pain score of mixed hemorrhoids patients was evaluated 5, 24, 48, 72 and 96 h after operation by using visual analogue scales (VAS). The complications, analgesics use and adverse reactions were recorded simultaneously. RESULTS: Comparison between two groups showed that the VAS scores of the catgut implantation group at 5, 24, 48, 72 and 96 h after operation were significantly lower than those of the medication group (P < 0.05). The incidence of complications of uroschesis and hydroncus, adverse reactions of nausea, vomiting and vertigo, and the number of patients using Sauteralgyl were significantly lower in the catgut implantation group than in the medication group (P < 0.05). CONCLUSION: Catgut implantation at BL 57 can effectively relieve the postoperative pain, reduce postoperative adverse reactions and complications in mixed hemorrhoids patients.
