The intestine harbors a large population of microorganisms that interact with epithelial cells to maintain host healthy physiological status. These intestinal microbiota engage in the fermentation of non-digestible nutrients and produce beneficial metabolites to regulate host homeostasis, metabolism, and immune response. The disruption of microbiota, known as dysbiosis, has been implicated in many intestinal diseases, including colorectal cancer (CRC). As the third most common cancer and the second leading cause of cancer-related death worldwide, CRC poses a significant health burden. There is an urgent need for novel interventions to reduce CRC incidence and improve clinical outcomes. Modulating the intestinal microbiota has emerged as a promising approach for CRC prevention and treatment. Current research efforts in CRC probiotics primarily focus on reducing the incidence of CRC, alleviating treatment-related side effects, and potentiating the efficacy of anticancer therapy, which is the key to successful translation to clinical practice. This paper aims to review the traditional probiotics and new interventions, such as next-generation probiotics and postbiotics, in the context of CRC. The underlying mechanisms of probiotic anti-cancer effects are also discussed, including the restoration of microbial composition, reinforcement of gut barrier integrity, induction of cancer cell apoptosis, inactivation of carcinogens, and modulation of host immune response. This paper further evaluates the novel strategy of probiotics as an adjuvant therapy in boosting the efficacy of chemotherapy and immunotherapy. Despite all the promising findings presented in studies, the evaluation of potential risks, optimization of delivery methods, and consideration of intra-patient variability of gut microbial baseline must be thoroughly interpreted before bench-to-bedside translation.

Objective: To establish the norms and clinical application standards of mass spectrometry method to measure vitamin D in capillary blood. Methods: Following the "Province-City-Hospital" sampling procedure, a cross-sectional sample of 1 655 healthy children under 7 years of age were recruited from 12 provinces, autonomous regions, or municipalities in China from November 2020 to December 2021. Both venous and capillary blood samples from the same individual were collected, for which serum 25(OH)D levels were measured by high-performance liquid chromatography-mass spectrometry (HPLC-MS/MS) method. Pearson correlation analysis and linear regression analysis were used to detect the correlation and determine a correction algorithm. The agreement was analyzed using Bland-Altman plot and Kappa statistic. The sensitivity and specificity were evaluated using receiver operating characteristic (ROC) curve method. Results: Venous and capillary 25(OH)D levels of 1 655 healthy children under 7 years of age were 74.25 (59.50, 92.00) and 68.75 (54.44, 86.25) nmol/L, respectively, showed a significant difference(Z=22.14, P<0.001) as well as a highly significant correlation between venous and capillary 25(OH)D levels(r=0.95, P<0.001). Linear regression analysis was then performed to determine the correction algorithm: lg(corrected capillary 25(OH)D)=0.13+0.95×lg(capillary 25(OH)D)(R²=0.90,P<0.001). The deviation between venous and corrected capillary 25(OH)D levels was (0.50±17.50) nmol/L, a difference value that did not reach statistical significance (P>0.05). The cut-off values of capillary blood 25(OH)D values 30.00, 50.00, 75.00 nmol/L corresponding to venous blood 25(OH)D values were 26.59, 45.56, and 69.84 nmol/L, respectively. Good consistency was observed between venous and corrected capillary 25(OH)D levels in clinical diagnosis (Kappa value 0.68-0.81). Corrected capillary 25(OH)D showed a high clinically predictive value (area under curve 0.97-0.99,sensitivity 0.72-0.92,specificity 0.89-0.99). Conclusion: The standardized capillary HPLC-MS/MS method can be used to detect 25(OH)D levels in children clinically.

Ten compounds were isolated from the 95% ethanol extract of the whole plant of Gerbera piloselloides by silica gel column chromatography, MCI column chromatography and semi-preparative HPLC methods. Their structures were identified on the basis of physicochemical properties, spectral data (UV, IR, MS and NMR), circular dichroism (CD) spectra and single crystal X-ray diffraction analysis as 3′R-gerpilosecoumarin A (1a), 3′S-gerpilosecoumarin A (1b), gymnastone (2), gerberinside (3), divaricataester C (4), luteolin (5), caffeic acid methyl ester (6), ethyl chlorogenate (7), 6-(β-D-glucopyranosyloxy)-7-methoxy-5-benzoranpropanoic acid methyl ester (8) and glucozaluzanin C (9). Among them, new compounds 1a and 1b were new compounds and optical enantiomers, which were obtained by chiral resolution, and their absolute configurations were determined by quantum chemical calculation ECD. Compounds 1 and 1a/1b significantly increased the survival of IEC-6 in rat small intestinal crypt epithelial cells after LPS injury.

Objective: To explore current vitamin D status and influential factors of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China. Methods: According to the "province-city-hospital" sampling technical route, a total of 1 531 healthy children under 7 years of age were sampled from 11 provinces, autonomous regions or municipalities in China by the cluster random sampling method from November 2020 to November 2021. The demographic information, family conditions, behavior and living habits and feeding behaviors were collected using unified questionnaire. Serum 25-hydroxyvitamin D(25(OH)D) levels were measured by liquid chromatography-tandem mass spectrometry. Serum 25(OH)D<30 nmol/L was considered deficient and 30-50 nmol/L was considered insufficient. With 25(OH)D≤50 nmol/L as the dependent variable, multivariate Logistic regression was applied to analyze the association between vitamin D deficiency and insufficiency and potential influential factors. Results: The prevalence of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China was 14.0% (215/1 531), 3.8% (25/664) and 21.9% (190/867) in 0-<3 and 3-<7 of age years, respectively. Compared to children aged 0-<3 years, children aged 3-<7 years had a 2.6-fold increased risk of vitamin D deficiency and insufficiency (OR=3.60, 95%CI 1.93-6.72, P<0.001). Frequent sunlight exposure (OR=0.46, 95%CI 0.29-0.73, P=0.001), vitamin D supplementation (sometimes, OR=0.33, 95%CI 0.21-0.51, P<0.001; daily, OR=0.20, 95%CI 0.11-0.36, P<0.001) and infant formula intake(4-7 times per weeks, OR=0.43, 95%CI 0.28-0.68, P<0.001) were protective factors for vitamin D deficiency and insufficiency. Conclusion: Vitamin D deficiency and insufficiency are common among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China, which is affected by age, sunlight exposure, vitamin D supplementation and infant formula intake.

Background/Aims: Cigarette smoking is an important modifiable risk factor in kidney disease progression. However, the underlying mechanisms for this are lacking. This study aimed to assess whether nicotine (NIC), a major toxic component of cigarette smoking, would exacerbates tacrolimus (TAC)-induced renal injury. Methods: Sprague-Dawley rats were treated daily with NIC, TAC, or both drugs for 4 weeks. The influence of NIC on TAC-caused renal injury was examined via renal function, histopathology, oxidative stress, mitochondria, endoplasmic reticulum (ER) stress, and programmed cell death (apoptosis and autophagy). Results: Both NIC and TAC significantly impaired renal function and histopathology, while combined NIC and TAC treatment aggravated these parameters beyond the effects of either alone. Increased oxidative stress, ER stress, mitochondrial dysfunction, proinf lammatory and profibrotic cytokine expressions, and programmed cell death from either NIC or TAC were also aggravated by the two combined. Conclusions Our observations suggest that NIC exacerbates chronic TAC nephrotoxicity, implying that smoking cessation may be beneficial for transplant smokers taking TAC.

Clinical practice guideline on traditional Chinese medicine therapy alone or combined with antibiotics for sepsis is strictly in accordance with the latest diagnostic criteria for sepsis (sepsis-3) for the treatment of septic patients at different stages through syndrome differentiation. At present, the abuse of antibiotics and the prevalence of drug-resistant bacteria are very serious, without effective solutions. Thus, this is the first time to focus on traditional Chinese medicine combined with antibiotics to treat sepsis, in order to minimize the incidence of drug-resistant bacteria. This Guideline tends to systematically analyze the sepsis period, septic shock period as well as different clinical symptoms and traditional Chinese medicine measures for organ dysfunction in the sepsis process. By analyzing and interpreting the Guideline systematically, the clinicians could understand its purpose, significance and core ideas more thoroughly, and grasp the recommended specific interventions as well as their advantages and disadvantages, hoping to better implement the Guideline, provide guidance to clinicians and standardize the treatment of sepsis by traditional Chinese medicine.

Symptomatic pancreatic ductal stones can be removed nonsurgically by endoscopic retrograde cholangiopancreatography (ERCP), either alone or in combination with extracorporeal shock-wave lithotripsy (ESWL). Here, we report a case of successful endoscopic ultrasonography (EUS)-guided rendezvous ERCP for removal of radiolucent pancreatic stones after failed ERCP and ESWL. A 79-year-old male with painful chronic pancreatitis associated with pancreatic stones and a dilated upstream duct underwent transgastric antegrade pancreatography via EUS-guided pancreatic duct access followed by rendezvous ERCP. In this patient, EUS-guided rendezvous ERCP was successful in salvaging pancreatic duct cannulation after unsuccessful ERCP due to a tight stricture at the pancreatic duct orifice and removing radiolucent pancreatic stones after ESWL, which was unsuccessful because of failure to localize the stones due to their radiolucency under x-ray fluoroscopy.
