RESUMEN
Wasps play important roles as predators and pollinators in the ecosystem. The Jingpo minority residing in Yunnan Province, China, has a traditional practice of using wine infused with mature wasps as a customary remedy for managing rheumatoid arthritis. The larva of the wasp is also a tasteful folk dish that has created a tremendous market. There is a paucity of survival knowledge, which has greatly restricted their potential applications in food and healthcare. Recent research has highlighted the importance of gut microbiota in insect growth. Nevertheless, there is still a lack of understanding regarding the composition, changes, and functions of the gut microbiota in Vespa mandarinia during development. In this research, the gut microbiota were investigated across three growth stages of Vespa mandarinia using a metagenomic technology. The result revealed that there are significant variations in the proportion of main gut microbes during the metamorphosis of Vespa mandarinia. Tenericutes were found to dominate during the larval stage, while Proteobacteria emerged as the dominant group post-pupation. Through a comprehensive analysis of the gut microbiota metagenome, this study revealed functional differences in the wasp gut microbiota at various growth stages. During the larval stage, the gut microbiota plays a central role in promoting metabolism. Following pupation, the gut microbiota exhibited diversified functions, likely due to the complex environments and diverse food sources encountered after metamorphosis. These functions included amino acid metabolism, compound degradation, and defense mechanisms. This research provides an extensive dataset on the gut microbiota during the metamorphosis of Vespa mandarinia, contributing to a deeper understanding of the influence of gut microbiota on wasp growth. Furthermore, this study uncovers a unique microbial treasure within insect guts, which is important for advancing the application of wasps in the fields of food and medicine.
RESUMEN
Background: Yoga is a non-pharmacological conservative therapeutic modality that can be employed for the management of chronic low back pain (CLBP). In this overview, we have summarized and evaluated data from current systematic reviews (SRs) on the use of yoga for CLBP. Methods: We comprehensively searched SRs on the use of yoga for CLBP in nine electronic databases from inception to September 2023. The methodological quality was evaluated using the Assessment of Multiple Systematic Review Scale-2 (AMSTAR-2). The reporting quality of the included SRs was evaluated using the Preferred Reporting Item for Systematic Review and Meta-Analysis-2020 (PRISMA-2020), and the quality of data was graded using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Two independent researchers performed the screening, data extraction, and quality assessment process of SRs. Results: A total of 13 SRs were included. The results of the AMSTAR-2 indicated that the methodological quality of the included studies was relatively low. The PRISMA-2020 checklist evaluation results indicated that methodological limitations in reporting, especially regarding data processing and presentation, were the main weaknesses. The GRADE assessment indicated that 30 outcomes were rated moderate, 42 were rated low level, and 20 were rated very low level. Downgrading factors were mainly due to the limitations of the included studies. Conclusion: Yoga appears to be an effective and safe non-pharmacological therapeutic modality for the Management of CLBP. Currently, it may exhibit better efficacy in improving pain and functional disability associated with CLBP. However, the methodological quality and quality of evidence for SRs/MAs in the included studies were generally low, and these results should be interpreted cautiously.

OBJECTIVE: To explore the proliferation inhibitory effect of quinones from Blaps rynchopetera defense secretion on colorectal tumor cell lines. METHODS: Human colorectal cancer cell HT-29, human colorectal adenocarcinoma cell Caco-2 and normal human colon epithelial cell CCD841 were chosen for the evaluation of inhibitory activity of the main quinones of B. rynchopetera defense secretion, including methyl p-benzoquinone (MBQ), ethyl p-benzoquinone (EBQ), and methyl hydroquinone (MHQ), through methyl thiazolyl tetrazolium assay. The tumor-related factors, cell cycles, related gene expressions and protein levels were detected by enzyme-linked immunosorbent assy, flow cytometry, RT-polymerase chain reaction and Western blot, respectively. RESULTS: MBQ, EBQ, and MHQ could significantly inhibit the proliferation of Caco-2, with half maximal inhibitory concentration (IC50) values of 7.04 ± 0.88, 10.92 ± 0.32, 9.35 ± 0.83, HT-29, with IC50 values of 14.90 ± 2.71, 20.50 ± 6.37, 13.90 ± 1.30, and CCD841, with IC50 values of 11.40 ± 0.68, 7.02 ± 0.44 and 7.83 ± 0.05 µg/mL, respectively. Tested quinones can reduce the expression of tumor-related factors tumor necrosis factor α, interleukin (IL)-10, and IL-6 in HT-29 cells, selectively promote apoptosis, and regulate the cell cycle which can reduce the proportion of cells in the G1 phase and increase the proportion of the S phase. Meanwhile, tested quinones could up-regulate mRNA and protein expression of GSK-3ß and APC, while down-regulate that of ß-catenin, Frizzled1, c-Myc, and CyclinD1 in the Wnt/ß-catenin pathway of HT-29 cells. CONCLUSION: Quinones from B. rynchopetera defense secretion could inhibit the proliferation of colorectal tumor cells and reduce the expression of related factors, which would be functioned by regulating cell cycle, selectively promoting apoptosis, and affecting Wnt/ß-catenin pathway-related mRNA and protein expressions.

To systematically evaluate the clinical efficacy and safety of modified Qingjin Huatan Decoction in the treatment of community-acquired pneumonia in the elderly, and provide evidence-based reference for the clinical application of this prescription. Randomized controlled trials of Qingjin Huatan Decoction in the treatment of community-acquired pneumonia in the elderly were collected by searching PubMed, EMbase, Cochrane Library, CNKI, China Biomedical Literature database, VIP database and WanFang database. Outcome indicators included clinical effective rate, inflammation index, symptom improvement time, chest radiograph improvement time, hospitalization time and adverse reactions. RevMan 5.3 and Stata/IC 15.1 software were used for Meta-analysis; TSA 0.9.5.10 Beta software was used for trial sequential analysis, and GRADE profiler 3.6 was used for grade evidence quality evaluation. Thirteen studies were included finally, including 1 058 patients, 536 patients in the experimental group and 522 patients in the control group.Meta-analysis showed that, the clinical effective rate of the experimental group was significantly higher than that of the control group(RR=1.16, 95%CI[1.10, 1.21], P<0.000 01); fever time(MD=-1.32, 95%CI[-1.93,-0.71], P<0.000 1), cough time(MD=-1.95, 95%CI[-2.69,-1.21), P<0.000 01), time to rale disappearance(MD=-1.55, 95%CI[-2.37,-0.73], P=0.000 2), time to chest radiograph improvement(MD=-1.72, 95%CI[-2.98,-0.46], P=0.007), and hospitalization time(MD=-3.16, 95%CI[-4.58,-1.74], P<0.000 01) in the experimental group were significantly shorter than those in the control group. The improvement in CRP(WMD=-3.44,95%CI[-4.50,-2.38],P<0.001), WBC(WMD=-2.04,95%CI[-3.31,-0.78],P<0.01), IL-6(WMD=-4.27,95%CI[-4.62,-3.92],P<0.001), and TNF-α(WMD=-0.47,95%CI[-0.55,-0.39], P<0.001) of the experimental group was significantly better than that of the control group. There was no significant difference in PCT improvement between the two groups(WMD=-0.63, 95%CI[-1.65, 0.40], P=0.23). No serious adverse reactions occurred in both groups. Sequential analysis of the trial showed that in the studies with cumulative inclusion of clinical effective rate, the data passed the traditional threshold and TSA threshold, further confirming its clinical efficacy. GRADE evaluation showed that the evidence level was low to extremely low. Western medicine treatment combined with Qingjin Huatan Decoction may improve clinical efficiency in the treatment of community-acquired pneumonia in the elderly, improve clinical symptoms faster, reduce CRP, WBC and other inflammatory indicators, and shorten hospital stay. The level of evidence obtained in this study is low, which needs to be further verified by high-quality multi-center, randomized controlled trials.

To evaluate the clinical efficacy and safety of Shentong Zhuyu Decoction in the treatment of lumbar disc herniation, in order to provide evidence for its clinical application. PubMed, Cochrane Library, EMbase, CNKI, WanFang, VIP, CBM and Clinical Trials.gov databases were sysmatically retrieved. Two researchers independently searched, screened and extracted data. Randomized controlled trials in line with the inclusion criteria were included in the study. The article quality was assessed with the bias risk tool in the Cochrane Handbook. Meta-analysis was performed using RevMan 5.3. A total of 604 articles were obtained from the retrieval, and 824 patients in 9 studies were finally selected through screening. The course of treatment was about 1 month, and all of the studies were completed in China. Meta-analysis showed that the efficacy of Shentong Zhuyu Decoction in the treatment of lumbar disc herniation was better than that of the control group(RR=1.19, 95%CI[1.12, 1.26], P<0.000 01), including the comparison with Yaotongning Capsules(RR=1.10, 95%CI[1.02, 1.19], P=0.01) and diclofenac sodium tablets(RR=1.26, 95%CI[1.11, 1.44], P=0.000 4). In VAS pain score, Shentong Zhuyu Decoction had also obvious advantages(MD=-3.70, 95%CI[-6.31,-1.09], P=0.005). In addition, the number of adverse events in the Shentong Zhuyu Decoction group was lower than that in the control group. Shentong Zhuyu Decoction can effectively alleviate discomfort symptoms of patients with LDH. It has an obvious clinical efficacy and less adverse reactions. However, restricted by the quality of the included literatures, prospective, multi-center, large-sample-size randomized controlled trials are still needed to further improve the clinical evidence of the effect of Shentong Zhuyu Decoction in the treatment of LDH.

The aim of this paper was to investigate the key targets and mechanism of "Epimedii Folium-Paeoniae Radix Alba" in the treatment of lumbar disc herniation by means of network pharmacology. The currently recognized databases and analysis software at home and abroad were used to construct the network from drugs and diseases. The chemical components of Epimedii Folium and Paeo-niae Radix Alba were collected by using databases such as TCMSP, while their active components were determined and the action targets were predicted according to threshold screening and literature reports. The genes for lumbar disc herniation were collected by using GeneCards, OMIM, and DisGeNET databases. The drug targets were mapped to disease targets, and protein interaction network analysis for key targets, GO function enrichment analysis and KEGG signaling pathway enrichment analysis were performed. Finally, 23 active components of Epimedium Folium and 13 active components of Paeoniae Radix Alba were determined, and a total of 624 drug targets were obtained. After standardization, 214 drug targets were obtained. In addition, 306, 2 and 5 related targets of lumbar disc herniation were collected from GeneCards, OMIM, and DisGeNET database, respectively, and a total of 293 disease targets were obtained after deduplication. After the mapping of drug target and disease target, 44 common targets were obtained. PPI protein interaction network analysis showed that IL-6, TNF, AKT1, MAPK1, and VEGFA may be the core targets for the treatment of lumbar disc herniation. GO enrichment analysis identified 56 items(P<0.05), among which biological processes mainly included immune response, apoptosis, etc.; cell components mainly included extracellular space, extracellular region, etc.; molecular functions mainly included cytokine activity, metallopeptidase activity and so on. Through KEGG pathway enrichment analysis, 91 signaling pathways related to inflammation, metabolism, and senescence were identified, mainly including IL-17 signaling pathway and TNF signaling pathway and so on. "Epimedii Folium-Paeoniae Radix Alba" showed the characteristics of multi-channel and multi-target for the treatment of lumbar disc herniation. This study preliminarily explored the key targets for its role and the biological processes and signaling pathways involved. It was found that it may play a therapeutic role by affecting inflammation and immune regulation, which laid the foundation for further experimental verification.

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease involving both upper and lower motor neurons with no effective cure. Electrophysiological studies have found decremental responses during low-frequency repetitive nerve stimulation (RNS) except for diffused neurogenic activities. However, the difference between ALS and generalized myasthenia gravis (GMG) in terms of waveform features is unclear. In the current study, we explored the variation trend of the amplitudes curve between ALS and GMG with low-frequency, positive RNS, and the possible mechanism is discussed preliminarily. METHODS: A total of 85 ALS patients and 41 GMG patients were recruited. All patients were from Peking Union Medical College Hospital (PUMCH) between July 1, 2012 and February 28, 2015. RNS study included ulnar nerve, accessory nerve and facial nerve at 3âHz and 5âHz stimulation. The percentage reduction in the amplitude of the fourth or fifth wave from the first wave was calculated and compared with the normal values of our hospital. A 15% decrease in amplitude is defined as a decrease in amplitude. RESULTS: The decremental response at low-frequency RNS showed the abnormal rate of RNS decline was 54.1% (46/85) in the ALS group, and the results of different nerves were 54.1% (46/85) of the accessory nerve, 8.2% (7/85) of the ulnar nerve and 0% (0/85) of the facial nerve stimulation, respectively. In the GMG group, the abnormal rate of RNS decline was 100% (41/41) at low-frequency RNS of accessory nerves. However, there was a significant difference between the 2 groups in the amplitude after the sixth wave. CONCLUSIONS: Both groups of patients are able to show a decreasing amplitude of low-frequency stimulation RNS, but the recovery trend after the sixth wave has significant variation. It implies the different pathogenesis of NMJ dysfunction of these 2 diseases.

In previous work, a series of bioactive natural products had been isolated from the plant endophytic Streptomyces sp. CS, which was isolated from Maytenus hookeri. To mine new active metabolites, we describe introducing an alien carbamoyltransferase (asm21) gene into the strain CS by conjugal transfer. As a result, three recombinatorial mutants named CS/asm21-1, CS/asm21-2 and CS/asm21-4 were successfully constructed. Three mutants and wild type CS were cultured on solid medium, and the extracts were detected and analyzed by liquid chromatography-mass spectrometry (LC-MS). The LC-MS profiles showed several unknown peaks that were present in the spectra of extracts of the CS/asm21-4 cultured on oatmeal solid medium. Then, three new naphthomycins O-Q (1-3), a new macrolide hookerolide (4) as well as nine known compounds were obtained from the solid cultured medium. Their structures were identified by spectra data. These new compounds showed moderate antimicrobial activities.

RESUMEN
To explore the clinical medication rules in the patients with limb fractures, and provide guidance for clinical practice. Data of 48 398 patients with limb fractures from 2001 to 2011 was extracted from the hospital information system(HIS) established by the institute of basic research in clinical medicine, China academy of Chinese medical sciences. The gender and age distribution of patients and clinical medication characteristics were described. Apriori algorithm was adopted to analyze the common drug combinations of Chinese medicine(CM) and western medicine(WM). The study results showed that the ratio of included males and females was 1.83â¶1. There was a high peak of incidence for the patients from 18 to 44 years. Apriori algorithm showed that the usage of WM was more frequent than that of CM. The most commonly used CM was Lugua polypeptide and sodium aescinate injection. Blood-activating and stasis-resolving medicines, as well as tendons and bones-strengthening medicines were the commonly used CM types. In addition, WM antibiotics plus blood-activating and stasis-resolving CM, or antibiotics plus tendons and bones-strengthening CM was the most commonly used drug combination. Based on the analysis of available data, the prevalence of limb fracture was higher in men than in women; more in young and middle-aged patients; the common drug combination was antibiotics plus blood-activating and stasis-resolving CM, or antibiotics plus tendons and bones-strengthening CM. More prospective and high-quality clinical trials are necessary to evaluate the effect of CM or integrative medicine treatment for limb fracture in the future research.
