Polycystic ovary syndrome(PCOS) and its resulting infertility is one of the common diseases of gynecology and reproductive endocrinology. The phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt) signaling pathway is relatively well-studied in the development of intervention in PCOS, and the experiments on PCOS in rats conducted by traditional Chinese medicine through this signaling pathway is also the main direction of mechanistic research. In this paper, 20 articles published in academic journals in the past 5 years were selected through the corresponding criteria, and the objective situation and existing problems of the selected research projects were analyzed from five aspects, namely, baseline data, modeling and treatment, grouping, evaluative indexes, and pharmacodynamic indexes. It is found that there were different degrees of problems in each research project, such as the observation indicators of modeling, criteria for judging the success of the model, the treatment period, the calculation of dosage of prescription/active ingredients and specific dosage were not clearly defined, which could easily lead the bias of the results or reduce the validity of experimental data. Based on this, the list of PCOS rat experimental research operations was formed, involving five categories of experimental rats, model construction, study implementation, outcome measures and analysis and report with a total of 21 operation lists, with a view to provide a reference for the subsequent PCOS experiments related to scientific research and helping to form high-quality results.

The concept of holism is the core idea of traditional Chinese medicine (TCM). Various organs and tissues coordinate with each other to maintain the body's life activities, with a close and mutual influence between the spleen, stomach, and the central nervous system (brain). The gut-brain axis plays an important bridging role between the digestive system and the central nervous system, achieving bidirectional information exchange between the brain and the gastrointestinal tract through complex neuroendocrine and immune mechanisms. The theory of cross-organ interaction involves the mutual influence, coordination, and integration between different organs and systems; multimodality, on the other hand, utilizes multiple sensory modalities, such as vision, hearing, and touch, to convey information. By combining TCM theory with the gut-brain axis theory, a cross-organ multimodal characterization system is established to explore its mechanism and application value in refractory diseases such as functional gastrointestinal disorders, precancerous gastrointestinal diseases, Alzheimer's disease, Parkinson's syndrome, type 2 diabetes, and depression.

ObjectiveTo study the effect of Taikong Yangxin Pills on the metabolism of simulated weightless rats based on metabolomics and discuss the metabolism mechanism. MethodsIn the simulated space capsule environment on the ground, the rat model of simulated weightlessness was established by the tail suspension method. Rats were randomly grouped as follows: out-of-capsule control, in-capsule control, model, and high (3.0 g·kg-1) and low (1.5 g·kg-1) doses of Taikong Yangxin Pills, and they were administrated with corresponding drugs by gavage for 28 days. The serum levels of endogenous metabolites in rats were determined by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS). The obtained data were processed by principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) to screen for differential metabolites and potential biomarkers. MetaboAnalyst 5.0 was used for pathway enrichment analysis to explain the metabolic regulation mechanism of the drug. ResultsCompared with the out-of-capsule control group, the in-capsule control group showed elevated levels of thirteen metabolites, including 14-hydroxyhexadecanoic acid, linoleic acid, and α-linolenic acid (P<0.05), which suggested that the space capsule environment mainly affected the metabolism of α-linolenic acid and linoleic acid in the rats. Compared with the in-capsule control group, the model group showed lowered levels of fourteen metabolites, including 4-imidazolone-5-propionic acid, isocitric acid/citric acid, and L-tyrosine (P<0.05), which were recovered after the treatment with Taikong Yangxin pills (P<0.05). The pathway enrichment analysis revealed that weightlessness induced by tail suspension and drug intervention mainly involved the phenylalanine, tyrosine, and tryptophan biosynthesis, tyrosine metabolism, histidine metabolism, and citric acid cycle. ConclusionThe simulated space capsule environment and simulated weightlessness induced by tail suspension can both affect the metabolism level of rats. Taikong Yangxin pills can ameliorate the metabolic abnormality in the rat model of weightlessness by regulating various amino acids and energy metabolism-related pathways.

Sepsis is a systemic inflammatory response syndrome caused by the invasion of pathogenic microorganisms such as bacteria. In addition to the manifestations of systemic inflammatory response syndrome and primary infection lesions, critical cases often have manifestations of organ hypoperfusion. The morbidity and mortality of sepsis have remained high in recent years, which seriously affect the quality of life of the patients. The pathogenesis of sepsis is complicated, in which uncontrollable inflammation is a key mechanism. The phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway plays a key role in mediating inflammation in sepsis. The available therapies of sepsis mainly include resuscitation, anti-infection, vasoactive drugs, intensive insulin therapy, and organ support, which show limited effects of reducing the mortality. Therefore, finding new therapeutic drugs is a key problem to be solved in the clinical treatment of sepsis. In recent years, studies have shown that traditional Chinese medicine (TCM) can regulate the PI3K/Akt pathway via multiple pathways, multiple effects, and multiple targets to inhibit inflammation and curb the occurrence and development of sepsis, which has gradually become a hot spot in the prevention and treatment of sepsis. Moreover, studies have suggested that TCM has unique advantages in the treatment of sepsis. TCM can regulate the PI3K/Akt signaling pathway to inhibit inflammation, reduce oxidative stress, and control apoptosis in the prevention and treatment of sepsis. Despite the research progress, a systematic review remains to be performed regarding the TCM treatment of sepsis by regulating the PI3K/Akt signaling pathway. After reviewing relevant papers published in recent years, this study systematically summarizes the relationship between PI3K/Akt pathway and sepsis and the role of TCM in the treatment of sepsis, aiming to provide new ideas for the potential treatment of sepsis and the development of new drugs.

OBJECTIVE To optimize the simmering technology of Rheum palmatum from Menghe Medical School and compare the difference of chemical components before and after processing. METHODS Using appearance score, the contents of gallic acid, 5-hydroxymethylfurfural (5-HMF), sennoside A+sennoside B, combined anthraquinone and free anthraquinone as indexes, analytic hierarchy process (AHP)-entropy weight method was used to calculate the comprehensive score of evaluation indicators; the orthogonal experiment was designed to optimize the processing technology of simmering R. palmatum with fire temperature, simmering time, paper layer number and paper wrapping time as factors; validation test was conducted. The changes in the contents of five anthraquinones (aloe-emodin, rhein, emodin, chrysophanol, physcion), five anthraquinone glycosides (barbaloin, rheinoside, rhubarb glycoside, emodin glycoside, and emodin methyl ether glycoside), two sennosides (sennoside A, sennoside B), gallic acid and 5-HMF were compared between simmered R. palmatum prepared by optimized technology and R. palmatum. RESULTS The optimal processing conditions of R. palmatum was as follows: each 80 g R. palmatum was wrapped with a layer of wet paper for 0.5 h, simmered on high heat for 20 min and then simmered at 140 ℃, the total simmering time was 2.5 h. The average comprehensive score of 3 validation tests was 94.10 (RSD<1.0%). After simmering, the contents of five anthraquinones and two sennosides were decreased significantly, while those of 5 free anthraquinones and gallic acid were increased to different extents; a new component 5-HMF was formed. CONCLUSIONS This study successfully optimizes the simmering technology of R. palmatum. There is a significant difference in the chemical components before and after processing, which can explain that simmering technology slows down the relase of R. palmatum and beneficiate it.

Objective:
To explore the causal association between dietary components (carbohydrate, fat, protein, and sugar) and 119 genera of known gut microbiota using Mendelian randomization (MR) methods.
Methods:
Genome-wide association study (GWAS) data for dietary components were collected from the DietGen, while GWAS data for gut microbiota were collected from the MiBioGen. Single nucleotide polymorphism (SNP) loci associated with the four dietary components were used as instrumental variables, and 119 known gut microbiota genera were used as the outcomes. MR analysis was performed using inverse variance weighted (IVW) method. Heterogeneity was evaluated using Cochran's Q test, horizontal pleiotropy and exclude outliers were tested using MR-Egger regression and MR-PRESSO test. Common genetic pleiotropic genes between dietary components and gut microbiota were identified by MAGMA and PLACO analyses.
Results:
The MR analysis revealed causal associations between carbohydrates and 4 gut microbiota genera, fats and 14 genera, proteins and 14 genera, and sugars and 11 genera (all P<0.05). The MR-Egger regression analysis showed no horizontal pleiotropy among the selected SNPs, and the MR-PRESSO test did not identify any outliers (all P>0.05). The MAGMA and PLACO analyses revealed that 74.42% (32/43) of the causal associations had pleiotropic genes, with 1 to 10 pleiotropic genes identified. Multiple causal association groups shared the same pleiotropic genes.
Conclusion
There are potential genetic and causal associations between dietary components and gut microbiota.

Objective To analyze the adverse reaction reports (ADRs) of drug-induced liver injury in recent ten years, explore the characteristics and related rules of drug-induced liver injury, and provide reference for clinical safe drug use. Methods ADRs in our hospital from 2011 to 2021 which belonged to drug-induced liver injuries were collected, and Pareto analysis was carried on. Results In 259 ADR reports, the most common type of drug-induced liver injury was hepatocellular injury (37.84%). The age of drug-induced liver injury was mainly over 46 years, totaling 195 (75.28%). Drugs were mainly distributed in cardiovascular system medicine (44.02%), anti-infective medicine (23.94%)and anti-tumor medicine (11.58%). Among the cardiovascular drugs, atorvastatin calcium 40mg and over 40mg were the highest proportion, with 53 cases (46.49%). The main anti-infectious drugs were cephalosporins (29.03%), carbapenem (19.35%), antifungal (17.74%)and quinolones (11.29%). Adverse reactions occurred within 6 days (69.88%), the duration of adverse reactions was 1-2 weeks (31.66%), and most patients were improved (47.88%) or cured (37.07%). Conclusion For middle-aged and elderly patients, when the application of cardiovascular system drugs, anti-infective drugs or anti-tumor drugs, it is necessary to monitor the liver function changes of patients for at least 6 days. If there are abnormalities, the drugs should be stopped or given treatment in time, to avoid the progress of drug-induced liver injury.

AIM:To analyze the association between mobile phone addiction and high myopia among college students.METHODS:We conducted a cross-sectional questionnaire survey in December 2022 on all students of a university in Shaanxi Province, and the questionnaire included socio-demographic characteristics, mobile phone addiction, high myopia, and lifestyle. Binary Logistic regression model was used to analyze the association between mobile phone addiction and high myopia among college students.RESULTS:A total of 19 952 college students were included. The prevalence of high myopia was 7.31%. The rate of mobile phone addiction was 25.68%, and the mobile phone addiction score was 37.59±13.38. The incidence of high myopia among college students with mobile phone addiction was higher than non-mobile phone addiction(P<0.001). After adjusting for socio-demographic characteristics and lifestyle, the risk of high myopia among college students with mobile phone addiction was 1.274 times(95%CI:1.131-1.434)higher than non-mobile phone addiction. For each point increase of total mobile phone addiction score, withdrawal symptoms score, salience score, social comfort score, and mood changes score, the risk of high myopia among college students increased by 0.9%(95%CI:1.005-1.013), 2.0%(95%CI:1.010-1.030), 2.6%(95%CI:1.010-1.043), 4.8%(95%CI:1.030-1.066), and 3.3%(95%CI:1.014-1.052), respectively.CONCLUSION:Mobile phone addiction is significantly associated with the increased risk of high myopia among college students, and early intervention of mobile phone use may reduce the risk of high myopia among college students.

[Objective] To evaluate the efficacy and safety of sacral neuromodulation (SNM) in the treatment of patients with benign prostatic hyperplasia (BPH) complicated with underactive bladder (UAB) who respond poorly to transurethral resection of the prostate (TURP). [Methods] A retrospective analysis was performed on 10 patients with BPH and UAB treated with TURP by the same surgeon in Zhongda Hospital Southeast University during Jan.2018 and Jan.2023.The residual urine volume was not significantly relieved after operation, and the maximum urine flow rate and urine volume per discharge were not significantly improved.All patients underwent phase I SNM, and urinary diaries were recorded before and after surgery to observe the average daily frequency of urination, volume per urination, maximum urine flow rate, and residual urine volume. [Results] The operation time was (97.6±11.2) min.During the postoperative test of 2-4 weeks, if the residual urine volume reduction by more than 50% was deemed as effective, SNM was effective in 6 patients (60.0%). Compared with preoperative results, the daily frequency of urination [(20.2±3.8) times vs. (13.2±3.2) times], volume per urination [(119.2±56.7) mL vs. (246.5±59.2) mL], maximum urine flow rate [(8.7±1.5) mL/s vs. (16.5±2.6) mL/s], and residual urine volume [(222.5±55.0) mL vs. (80.8±16.0) mL] were significantly improved, with statistical significance (P<0.05). There were no complications such as bleeding, infection, fever or pain.The 6 patients who had effective outcomes successfully completed phase II surgery, and the fistula was removed.During the follow-up of 1 year, the curative effect was stable, and there were no complications such as electrode displacement, incision infection, or pain in the irritation sites.The residual urine volume of the other 4 unsuccessful patients did not improve significantly, and the electrodes were removed and the vesicostomy tube was retained. [Conclusion] SNM is safe and effective in the treatment of BPH with UAB patients with poor curative effects after TURP.

To summarize Professor DING Ying's clinical experience in treating children's IgA nephropathy from the perspective of "wind-induced water turbidity". It is believed that the core pathogenesis of IgA nephropathy in children is the wind stimμlating water to become turbidity, and the basic treatment principles are to eliminate wind and settle viscera, and to remove turbidity and drain water. For those with the syndrome of wind-heat invading the lungs and injury to blood collaterals, modified Yinqiao Powder (银翘散) combined with Xiaoji Decoction (小蓟饮子) could be used; for those with dampness-heat in Sanjiao, heavy dampness and light heat pattern, modified Sanren Decoction (三仁汤) combined with Bazheng Powder (八正散) could be used; for those with lung-spleen qi deficiency and kidney essence depletion pattern, modified Buzhong Yiqi Decoction (补中益气汤) combined with Wuzi Yanzong Pill (五子衍宗丸) could be used; for those with deficiency of both qi and yin, kidney deficiency with stasis pattern, self-prescribed Yishen Huazhuo Formula (益肾化浊方) could be used. Meanwhile on the basis of pattern identification and treatment, rattan-type herbs could be combined in use in order to unblock the meridians and collaterals.
