ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

Background Animal farming may affect the structure and diversity of gut microbiota of farm workers, but it needs more studies to provide solid evidence. Objective To analyze the diversity characteristics of gut microbiota in dairy farm workers, dairy cows, and the control population (non-animal contact occupational group), and to assess the impact of dairy farming on the gut microbiota of workers. Methods The 16S rRNA full-length amplicon sequencing technology was used to sequence 60 fecal samples from dairy farm workers, 89 from dairy cows, and 50 from the general population. The gut microbiota structure characteristics, including operational taxonomic units (OTUs), alpha diversity, beta diversity, and the composition of species at the phylum, family, and genus levels were analyzed. The differences in gut microbiota among the three groups of samples were compared to explore the impact of occupational exposure on the gut microbiota structure of dairy farm workers. Results A total of 50478 OTUs were identified in the gut microbiota of farm workers, dairy cows, and the general population, with 23613, 42723, and 16592 OTUs, respectively. The number of shared OTUs between the dairy cows and the general population was 12674 (27.17%), between the general population and the farm workers was 10099 (33.54%), and between the dairy cows and the farm workers was 17690 (36.36%). Compared with the general population, the farm workers and dairy cows showed more shared gut microbiota (P<0.01). The abundance of Firmicutes in the gut of the farm workers was higher than that of the general population (P<0.01), while Actinobacteriota and Proteobacteria were the opposite (P<0.01). The alpha diversity of gut microbiota in the farm workers was different from that of the general population. The ACE index of the farm workers was slightly lower than that of the general population and much lower than that of dairy cows (P<0.05), while their Shannon index was higher than that of the general population but lower than that of dairy cows (P<0.01). The linear discriminant analysis effect size (LefSe) showed that the abundances of Lachnospiraceae and Ruminococcaceae in the gut microbiota of the farm workers were significantly higher than those of the general population, while Streptococcaceae, Lactobacillaceae, Bifidobacteriaceae, Enterobacteriaceae, and Erysipelatoclostridiaceae were lower than those of the general population. Conclusion The dairy farm workers shares a certain proportion of common bacterial communities with dairy cows. Dairy farming operations can affect the structure and diversity of the gut microbiota of workers by increasing the abundances of Lachnospiraceae and Ruminococcaceae, while decreasing the abundances of Streptococcaceae, Lactobacillaceae, Bifidobacteriaceae, Enterobacteriaceae, and Erysipelatoclostridiaceae. The study results provide reference data for further exploring the cross-host transmission of pathogens related to occupational exposure in dairy farming.

OBJECTIVE: To identify the protective effect of empagliflozin on ischemic brain injury and neurological dysfunction in mice, and further explore its potential mechanism. METHODS: Acute cerebral ischemia model was induced by the permanent middle cerebral artery occlusion surgery in C57BL/6J mice. Empagliflozin(10 and 30 mg·kg−1) was administered to mice one hour after the onset of occlusion. Brain infarct volume and neurological defect score were assayed 24 h after surgery. Mice were subjected to photo-thrombosis and further administered with empagliflozin 3, 10, 30 mg·kg−1 intragastricly for either 7 or 14 consecutive days. The grid-walking task and the cylinder task were performed daily to determine the sensory-motor function of the mice. Alternatively, the mice were treated with 10 mg·kg−1 empagliflozin simultaneously with 10% glucose(i.p.) for 7 consecutive days after the photo-thrombosis model to evaluate their motor sensory function. Immunofluorescence staining was used to detect the activation of microglia within the infarct area 7 d after the photo-thrombosis. RESULTS: One hour after permanent middle cerebral artery occlusion surgery, gavage of empagliflozin significantly increased the brain infarct volume and neurological dysfunction. While in photo-thrombosis surgery, treatment of empagliflozin(10 mg·kg−1) for consecutive 7 or 14 days significantly decreased the rate of false foot in grid-walking task and the assymetric index in cylinder task. At the dose of 30 mg·kg−1, however, empagliflozin even aggravated photo-thrombosis-induced neurological dysfunction, while the dose of 3 mg·kg−1 showed no effect. Unexpectedly, the protective effect of empagliflozin(10 mg·kg−1) could not be reversed by glucose treatment. The results of immunofluorescence showed that empagliflozin(10 mg·kg−1) significantly alleviated the microglia activation in the ischemic area after the photo-thrombosis operation. CONCLUSION Empagliflozin cannot protect against acute ischemia-induced brain injury in mice. Empagliflozin alleviated ischemia-induced neurological dysfunction with consecutive administration in a dose-related manner. Empagliflozin-conferred neuroprotection may not be attributable to its effects on lowing blood glucose. Alternatively, empagliflozin may play a neuroprotective effect by inhibiting the excessive activation of microglia in ischemic brains.

Objective To evaluate safety and efficacy of linaclotide combined with polyethylene glycol(PEG)for bowel preparation.Methods A total of 612 patients from Department of Gastroenterology at the Affiliated Hospital of Qingdao University for colonoscopy examination from January to June 2023 were selected.They were divided into group 1(1 L PEG+2 L PEG),group 2(linaclotide+2 L PEG)and group 3(1 L PEG+linaclotide+1 L PEG)by random number table method,with 204 cases in each group.The Ottawa Bowel Preparation Quality Scale(OBPS),the insertion time of colonoscopy,the time of the first defecation,the frequency of defecations,the occurrence of adverse effects and patients'tolerability were compared among the three groups.Results A total of 601 patients completed bowel preparation and accepted colonoscopy.Group 1 exhibited no statistically significant differences to group 2 with regards to OBPS and insertion time.However,Group 2 demonstrated a shorter duration for the time of the first defecation in comparison to both group 1 and group 3(P＜0.05).Group 1 displayed a higher frequency of defecations as compared to Group 2 and Group 3(P＜0.05).The incidence of adverse reactions was significantly lower in group 2 and group 3 than in group 1(P＜0.05).The overall tolerance score of patients in group 1 was low-er than that in group 2 and group 3(P＜0.05).Conclusions The effect of combining 2 L PEG with 290 μg of lina-clotide for bowel preparation before colonoscopy is similar to that of 3 L PEG.It can reduce the incidence of adverse reactions and patients exhibit good tolerance.For patients who are intolerant to a single high-dose administration of PEG,they need divided-dose regimen of 2 L PEG in combination with linaclotide.

Objective To explore the diagnostic value of energy spectrum CT quantitative parameters combined with serum thy-roid stimulating hormone receptor-messenger ribonucleic acid(TSHR-mRNA)for papillary thyroid microcarcinoma(PTMC).Methods A total of 105 patients with thyroid micronodules confirmed by surgery and pathology were collected,61 of whom were PTMC(PTMC group),and 44 patients with micronodular goiter(MNG)(MNG group).Energy spectrum CT quantitative parameters and serum TSHR-mRNA expression were compared between the two groups.The diagnostic value of energy spectrum CT quantitative parame-ters alone and combined with serum TSHR-mRNA for PTMC was analyzed by receiver operating characteristic(ROC)curve.Results The iodine concentration and slope of energy spectrum CT quantitative parameters between PTMC group and MNG group were signifi-cantly different in plain scan,arterial and venous phases(P＜0.05).The mean serum TSHR-mRNA expression in the PTMC group was higher than that in MNG group(P＜0.05).The area under the curve(AUC)for diagnosing PTMC using quantitative parame-ters of energy spectrum CT combined with serum TSHR-mRNA was 0.913,and the accuracy,sensitivity,and negative predictive value of diagnosing PTMC were significantly higher than those of quantitative parameters of energy spectrum CT or serum TSHR-mRNA(P＜0.05).Conclusion Both energy spectrum CT quantitative parameters and serum TSHR-mRNA can be used to diagnose PTMC alone,and the combination of both is more accurately.

ObjectiveTo observe the effects of Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the Haizao Yuhutang （HYT） on oxidative stress in the liver of goiter rats under the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020. MethodA total of 128 male Wistar rats were randomly divided into a blank group， a model group， a euthyrox group （20 μg·kg^-1）， a HYT group （12.06 g·kg^-1）， a HYT without Sargassum （HYT-H） group （9.90 g·kg^-1）， a HYT without Glycyrrhizae Radix et Rhizoma （HYT-G） group （10.26 g·kg^-1）， a HYT without Sargassum and Glycyrrhizae Radix et Rhizoma （HYT-HG） group （8.10 g·kg^-1）， and a Sargassum and Glycyrrhizae Radix et Rhizoma （HG） group （3.96 g·kg^-1）. The blank group was given deionized water by gavage， and the others were given propylthiouracil （PTU） to replicate the goiter pathological model. Euthyrox was taken as a positive control drug， and the rest of the Chinese medicine groups were given the corresponding decoction by gavage， the material was collected 12 hours after the last dose. The serum levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， and the contents of superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px）， malondialdehyde （MDA）， reactive oxygen species （ROS） in liver tissue were detected in each group. The pathological changes in the liver were observed via hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was utilized to detect the mRNA expressions of Kelch-like Ech-associated protein 1 （Keap1）， nuclear factor E₂-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， p53 and Caspase-3 in liver tissues. Western blot was adopted to detect the protein expressions of Nrf2 and HO-1 in liver tissues in oxidative stress-related signaling pathways. ResultCompared with control group， the model group showed significantly increased serum ALT level and contents of MDA and ROS in liver tissues （P<0.05， P<0.01）， significantly reduced activities of SOD and GSH-Px in the liver （P<0.01）， significantly increased mRNA expression of Keap1 （P<0.01）， and significantly decreased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. Compared with the model group， the HYT group manifested significantly reduced serum levels of AST， ALT， and ALP （P<0.05， P<0.01）， significantly reduced contents of MDA and ROS in liver tissue （P<0.01）， significantly increased the activities of SOD and GSH-Px （P<0.01）， significantly decreased mRNA expressions of Keap1， p53， and Caspase-3 （P<0.01）， and significantly increased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. ConclusionUnder the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020， Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the HYT on oxidative stress in the liver of goiter rats had different effects. The HYT that contains Sargassum and Glycyrrhizae Radix et Rhizoma has a protective effect on the liver of goiter rats， and the effect is better than that of the HG group， the euthyrox group， and the incomplete groups. Its mechanism may be related to activating the Nrf2/HO-1 signaling pathway to alleviate liver oxidative stress and inhibiting the p53/Caspase-3 signaling pathway to reduce hepatocyte apoptosis.

Objective:To investigate the clinicopathological and molecular genetic characteristics of well-differentiated/dedifferentiated liposarcoma (WDLPS/DDLPS) with myxoid-like morphology, and to distinguish them from myxofibrosarcoma (MFS) with similar morphology.Methods:Twenty-nine cases of myxoid-like liposarcoma and 5 cases of MFS were collected from Henan Provincial People′s Hospital, Zhengzhou, China and the First Medical Center of PLA General Hospital, Beijing, China from January 2015 to March 2023. Relevant markers were detected using immunohistochemistry and fluorescence in situ hybridization (FISH). The literature was also reviewed.Results:There were 24 males and 10 females, with ages ranging from 41 to 73 years. The tumor sites included retroperitoneum ( n=17), abdomen ( n=9), lower limbs ( n=5), scrotum ( n=1), upper limb ( n=1) and axilla ( n=1). WDLPS was commonly seen as lipomatoid type (12 cases), while the dedifferentiated components of DDLPS included low-grade (13 cases) and high-grade (2 cases) morphology, with low-high grade myxofibrosarcoma, dermatofibrosarcoma protuberans, and low-grade fibrosarcoma structures. Twenty-nine liposarcomas had various proportions of myxoid-like morphology, while 16 showed various degrees of tumor necrosis. The myxoid-like component showed myxoid pleomorphic liposarcoma (MLPS)-like morphology, lobulated growth, characteristic slender, ramified capillary network,"chicken claw-like"morphology, mucus-rich stroma and lung edema-like morphology. Tumor cells were spindle and oval, with many variable vacuolar lipoblasts. MDM2 gene amplification was detected using FISH and present in all tested cases (29/29). DDIT3 break-apart mutation was not detected, but its cluster amplification was present (24/29). Among the MFS cases, one showed cluster amplification (1/5), but no cases showed break-apart or amplification of MDM2 gene. Conclusions:WDLPS/DDLPS with myxoid-like morphology is most commonly seen in the retroperitoneum and abdominal cavity and mostly harbors DDIT3 break-apart probe amplification, while this amplification is not specific to liposarcoma. For core biopsy specimens or very rare tumors in the limbs, when histology has mucinous stroma and MLPS-like morphology, misdiagnosis of MLPS or other non-lipomatous neoplasms with myxoid morphology should be avoided.

Objective To evaluate the diagnostic efficacy of magnetic resonance defecography(MRD)in moderate or severe pelvic organ prolapse(POP)complicated with stress urinary incontinence(SUI).Methods Patients with grade Ⅱ or above POP were prospectively selected,and divided into POP combined with SUI group and isolated POP group.The MRD parameters of pelvic dysfunction between groups were analyzed to clarify the clinical diagnostic value and to evaluate the diagnostic efficacy of MRD in POP combined with SUI.Results This study enrolled 99 POP patients,42 patients in isolated POP group,and 57 patients in POP combined with SUI group.The comparison between groups showed there were significant differences in the function of the urethra and bladder,including the position of the urethro-vesical junction(1.61 cm±1.03 cm vs 2.13 cm±0.71 cm),the position of the posterior bladder wall(4.13 cm±2.46 cm vs 5.23 cm±2.21 cm),the urethra angle(94.22°±35.62°vs 114.28°±35.55°),the length of the closed urethra(2.28 cm±0.90 cm vs 2.15 cm±0.65 cm),and bladder funneling(23.81％vs 45.61％),all the differences were statistically significant(P＜0.05).The area under the curve(AUC)of multiple parameters MRD in the diagnosis of SUI was 0.73.The AUC in diagnosis of SUI by MRD combined with clinical history was 0.95.Conclusion POP combined with SUI has characteristic MRD signs.MRD technology can assist clinicians and improve the preoperative diagnosis rate of moderate and severe POP combined with SUI.
