Erectile dysfunction (ED) is prevalent among men, but its relationship with dietary habits is uncertain. The aim of our study was to assess whether dietary patterns enhance erectile function by reviewing the literature published before August 1, 2022, via PubMed, Web of Science, and EMBASE databases. The data compiled included author details; publication dates, countries, treatments, patient numbers, ages, follow-ups, and clinical trial outcomes, such as ED cases, odds ratios (ORs), confidence intervals (CIs), and International Index of Erectile Function-5 (IIEF-5) scores with means and standard deviations. An analysis of 14 studies with 27 389 participants revealed that plant-based diets (OR = 0.71, 95% CI: 0.66-0.75; P < 0.00001), low-fat diets (OR = 0.27, 95% CI: 0.13-0.53; P = 0.0002), and alternative diets such as intermittent fasting and organic diets (OR = 0.54, 95% CI: 0.36-0.80; P = 0.002) significantly reduced ED risk. High-protein low-fat diets (hazard ratio [HR] = 1.38, 95% CI: 1.12-1.64; P < 0.00001) and high-carb low-fat diets (HR = 0.79, 95% CI: 0.55-1.04; P < 0.00001) improved IIEF-5 scores. Combined diet and exercise interventions decreased the likelihood of ED (OR = 0.49, 95% CI: 0.28-0.85; P = 0.01) and increased the IIEF-5 score (OR = 3.40, 95% CI: 1.69-5.11; P < 0.0001). Diets abundant in fruits and vegetables (OR = 0.97, 95% CI: 0.96-0.98; P < 0.00001) and nuts (OR = 0.54, 95% CI: 0.37-0.80; P = 0.002) were also correlated with lower ED risk. Our meta-analysis underscores a strong dietary-ED association, suggesting that low-fat/Mediterranean diets rich in produce and nuts could benefit ED management.

Using a novel(OH)n-C60@SiO2@Tm2O3@Ca5(PO4)3(OH)quaternary nano-particles/cross-linked chitosan coated open-tubular capillary column(QNPsC-OTCC)as the analytical column,a new method for highly selective determination of taurine(TAU)in functional drinks using pre-column derivatization capillary electrochromatography coupled with electrochemiluminescence(CEC-ECL)detection was established.In the experiments,it was found that adding hexamethylenetetramine as a co-catalyst in N-methylation derivative reaction could quantitatively convert TAU into a single derivative product that cuold be detected by ECL.With the help of Ru(bpy)32+reagent,the ECL peak intensity of TAU derivative was increased by more than 1000 times compared to the original TAU.In addition,a Ru-containing d-f cyano-bridged heterometallic coordination polymer modified platinum electrode was used instead of a bare platinum electrode as working electrode for ECL detection,which resulted in a further increase of the peak response of TAU derivatives about 5.7 times.Under optimized analytical conditions,by using betastatin hydrochloride(BSH)as the internal standard and simultaneously derivatized with TAU,the relative ratio of peak intensity of TAU and BSH derivatives showed a linear relationship with the initial TAU concentration in a two-segment ranges of 0.2-6.0 mmol/L and 6.0-10 mmol/L.The limit of detection of TAU was 0.09 mmol/L(S/N=3).The developed method was applied to determination of TAU contents in four commercial functional drink samples,and the relative standard deviations(RSDs)for relative intensity ratio were less than 0.9％,and the recoveries were in the range of 95.0％～102.0％,indicating good practicability of the method.

Objective To measure the distance between the lateral compression Ⅱ(LC-Ⅱ)screw guide needle and the surrounding important structures around the anterior inferior iliac spine in pelvic fractures and to locate the needle point,so as to provide anatomical reference for clinical nail placement.Methods Totally 40 adult gross specimens of embalming were implanted with LC-Ⅱ screw guide needle under the surveillance of C-arm machine,and the specimens were dissected.The shortest distance between the insertion point and the lateral femoral cutaneous nerve,femoral nerve,femoral artery,femoral vein,anterior superior iliac spine and inguinal ligament was measured.The triangle was constructed between the insertion point,anterior superior iliac spine and inguinal ligament,and the exact location of the entry point was calculated.Results The average distance between the insertion point of the male needle and the femoral vein was(50.67±7.29)mm＞the anterior superior iliac spine(43.83±7.58)mm＞the femoral artery(38.35±6.63)mm＞the femoral nerve(31.17±1.67)mm=the inguinal ligament(28.69±6.59)mm＞the lateral femoral cutaneous nerve(7.98±3.81)mm.The mean distance between the insertion point of the female needle and the anterior superior iliac spine was(45.28±7.07)mm=femoral vein(43.72±6.89)mm＞femoral artery(33.76±6.33)mm＞femoral nerve(25.66±6.46)mm=inguinal ligament(23.22±5.00)mm＞lateral femoral cutaneous nerve(8.97±4.76)mm.The projection distance of the entry point was 31.77 mm for men and 38.41 mm for women.The Angle b was 42.81°for men and 31.71° for women.Conclusion The lateral femoral cutaneous nerve is most vulnerable to injury when LC-Ⅱ screw is inserted,and the risk of injury has nothing to do with sex.The insertion point positioning method a and b made LC-Ⅱ screw placement quickly,safely and accurately,and reduced fluoroscopy time and frequency.

Objective: To report the clinical manifestations and laboratory features of five patients with congenital thrombotic thrombocytopenic purpura (cTTP) and explore its standardized clinical diagnosis and treatment along with a review of literature. Methods: Clinical data of patients, such as age of onset, disease manifestation, personal history, family history, and misdiagnosed disease, were collected. Treatment outcomes, therapeutic effects of plasma infusion, and organ function evaluation were observed. The relationship among the clinical manifestations, treatment outcomes, and ADAMTS13 gene mutation of patients with cTTP was analyzed. Additionally, detection of ADAMTS13 activity and analysis of ADAMTS13 gene mutation were explored. Results: The age of onset of cTTP was either in childhood or adulthood except in one case, which was at the age of 1. The primary manifestations were obvious thrombocytopenia, anemia, and different degrees of nervous system involvement. Most of the patients were initially suspected of having immune thrombocytopenia. Acute cTTP was induced by pregnancy and infection in two and one case, respectively. ADAMTS13 gene mutation was detected in all cases, and there was an inherent relationship between the mutation site, clinical manifestations, and degree of organ injury. Therapeutic or prophylactic plasma transfusion was effective for treating cTTP. Conclusions: The clinical manifestations of cTTP vary among individuals, resulting in frequent misdiagnosis that delays treatment. ADAMTS13 activity detection in plasma and ADAMTS13 gene mutation analysis are important bases to diagnose cTTP. Prophylactic plasma transfusion is vital to prevent the onset of the disease.

In this study, the mechanism of Xiaoyan Lidan formula (XYLDF) against 3,5-diethoxycarbonyl-1,4-dihydro-2,4,6-collidine (DDC)-induced chronic intrahepatic cholestasis (CIHC) in mice was investigated based on metabolomics, molecular docking and pharmacological methods. In the pharmacodynamics study, a dosage of 5 g·kg^-1 (clinical equivalent) XYLDF was administered in DDC-induced mice, then the effect of XYLDF against CIHC was evaluated by measuring the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AKP) as well as total bilirubin (TBIL) in serum and observing liver histopathological changes. All experiments were approved by the Ethical Committee Experimental Animal Center of Guangzhou University of Chinese Medicine (ZYD-2021-001). The serum metabolites of mice in each group were detected and identified based on ultra-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry, and the relevant biological pathways and molecular key targets were further enriched. Molecular docking technology was used to further evaluate the binding activity of the main active ingredients of XYLDF with potential targets. Subsequently, the in vitro experiment was conducted for the validation of the vital target. The results showed that compared with the model group, XYLDF significantly decreased the levels of ALT, AST, AKP and TBIL in the serum of CIHC mice, as well as alleviated inflammatory infiltration and hepatocyte necrosis in liver tissue. According to the metabonomic study, a total of 35 differential metabolites was identified as biomarkers associated with cholestasis, 12 of which were significantly recovered by XYLDF treatment. These biomarkers were involved in the pathways of primary bile acid biosynthesis and linoleic metabolism, which are closely related to the mechanism of XYLDF against CIHC. Protein-protein interaction network indicated that cytochrome P450 3A4 (CYP3A4) and cytochrome P450 1A1 (CYP1A1) are significant potential targets with good binding properties with six major active ingredients of XYLDF. Furthermore, it was found that 4-methoxy-5-hydroxycanthin-6-one, dehydroandrographolide and isodocarpin, three of the main active components in XYLDF, markedly induced the expression of CYP3A4 mRNA in vitro. This study revealed that XYLDF mainly mediates the biosynthesis of bile acids in CIHC mice to improve liver tissue lesions and bile efflux disorders, among which, CYP3A4 is the key target in the protection of XYLDF against CIHC. This research provides a reference for further elucidation of the pharmacological mechanism of XYLDF.

According to the theory of 'Xingben Dazao' of Psoralea corylifolia Linn. (BL), the susceptible syndromes and biomarkers of liver injury caused by BL were searched. Rat models of kidney-yin deficiency syndrome (M_yin) and kidney-yang deficiency syndrome (M_yang) were established, and all animal experimental operations and welfare following the provisions of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Traditional Chinese Medicine (No. YFYDW2020017). The results showed that BL significantly decreased the body weight, water intake, and urine weight of M_yin rats and increase the organ indexes of the liver, testis, adrenal gland, and spleen and the expression of alanine aminotransferase (ALT). Meantime, BL significantly increased the urine weight of M_yang rats and decreased the expression of ALT and aspartate aminotransferase (AST). Hematoxylin and eosin (HE) staining showed that BL could aggravate inflammatory infiltration of hepatocytes in rats with M_yin and alleviate liver injury in rats with M_yang. Metabolomics identified 17 BL co-regulated significant differential metabolic markers in M_yin and M_yang rats. Among them, 8 metabolites such as glutamine, quinolinate, biliverdin, and lactosylceramide showed opposite trends, mainly involving cysteine and methionine metabolism, tyrosine metabolism, tryptophan metabolism, purine metabolism, sphingolipid metabolism, glycerol phospholipid metabolism, glutamine metabolism, and other pathways. M_yin/M_yang may be the susceptible constitution of BL for liver damage or protection, which may be related to the regulation of amino acid metabolism and sphingolipid metabolism. The study can provide some experimental data support for the safe and accurate use of BL in the clinical practice of traditional Chinese medicine.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

With the increasing incidence of hepatobiliary diseases, it is particularly important to understand the role of molecular, cellular and physiological factors in the clinical diagnosis and treatment with traditional Chinese medicine(TCM) in the development of liver disease. Appropriate animal models can help us identify the possible mechanisms of relevant diseases. Danio rerio(zebrafish) model was traditionally used to study embryonic development, and has been gradually used in screening and evaluation of liver diseases and relevant drug in recent years. Zebrafish embryos develop rapidly and the digestive organs of 5-day-old juvenile fish are all mature. At this stage, they may develop hepatobiliary diseases induced by developmental defects or compounds. Zebrafish liver is similar to human liver in cell composition, function, signal transduction, response to injury and cell process mediating liver disease. Furthermore, due to the high conservation of genes and proteins between humans and zebrafish, zebrafish becomes an alternative system for studying basic mechanisms of liver disease. Therefore, genetic screening could be performed to identify new genes involving specific disease processes, and chemical screening could be made for drugs in specific processes. This paper briefly introduced the experimental properties of zebrafish as model system, emphasized the study progress of zebrafish models for pathological mechanism of liver diseases, especially fatty liver, and drug screening and evaluation, so as to provide ideas and techniques for the future liver toxicity assessment of TCM.

Trigeminal neuropathic pain (TNP) is a significant health problem but the involved mechanism has not been completely elucidated. Toll-like receptors (TLRs) have recently been demonstrated to be expressed in the dorsal root ganglion and involved in chronic pain. Here, we show that TLR8 was persistently increased in the trigeminal ganglion (TG) neurons in model of TNP induced by partial infraorbital nerve ligation (pIONL). In addition, deletion or knockdown of Tlr8 in the TG attenuated pIONL-induced mechanical allodynia, reduced the activation of ERK and p38-MAPK, and decreased the expression of pro-inflammatory cytokines in the TG. Furthermore, intra-TG injection of the TLR8 agonist VTX-2337 induced pain hypersensitivity. VTX-2337 also increased the intracellular Ca
