		                        			Huaihuasan, first recorded in Experiential Prescriptions for Universal Relief (Pu Ji Ben Shi Fang), is a classic prescription for the treatment of ''hematochezia due to intestinal wind''. In 2018, it was included by the National Administration of Traditional Chinese Medicine as one of the first 100 classic prescriptions. This formula consists of four ingredients, i.e., Sophorae Flos, Platycladi Cacumen, Schizonepetae Spica, and Aurantii Fructus. It is known for its ability to clear the intestines, dispel wind, cool the blood, and stop bleeding. In modern clinical practice, Huaihuasan, often with modifications, is widely used to treat various digestive tract diseases, including ulcerative colitis (UC), with significant long-term effects. UC is a chronic, non-specific inflammatory bowel disease. Currently, Western medicine primarily treats UC with glucocorticoids, aminosalicylates, and immunosuppressants, which have good short-term efficacy but numerous adverse reactions, high recurrence rates, and the need for lifelong medication. Modern clinical studies have shown that Huaihuasan can significantly improve symptoms of UC, such as abdominal pain and diarrhea, reduce disease activity scores (Sutherland), promote intestinal mucosal healing, alleviate anxiety and depression, and significantly improve the quality of life of patients. Pharmacological studies have shown that the main active components of Huaihuasan include quercetin, rutin, kaempferol, naringenin, and volatile oils. These compounds exert their effects by inhibiting inflammatory responses and protecting the intestinal mucosal barrier. They also exhibit antioxidant properties and regulate various signaling pathways, including tumor necrosis factor-α (TNF-α), interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-1β (IL-1β), monocyte chemoattractant protein-1 (MCP-1), nuclear factor-κB (NF-κB), Janus kinase (JAK)/signal transducer and activator of transcription (STAT), and the KRAS-regulated mitogen-activated protein kinase (MEK)-extracellular signal-regulated kinase (ERK) pathway. These multi-target pathways improve UC symptoms, inhibit inflammation-cancer transition, and help maintain intestinal homeostasis. However, the precise mechanism of action has not yet been systematically elucidated. This paper reviews the research progress on Huaihuasan and main ingredients from its component drugs, focusing on their effects against UC. It also discusses current research limitations and suggests strategies for improvement, aiming to provide a reference for further studies on Huaihuasan in the treatment of UC and the development of new drugs.

		                        			BACKGROUND:After the treatment of femoral shaft fracture with the intramedullary nail,the third fracture open reduction indications are controversial.Some scholars believe that limited open reduction can achieve anatomical reduction,conducive to fracture healing;but some scholars believe that no open reduction of the third fracture still has a high fracture healing rate. OBJECTIVE:To investigate the effect of the circumference and displacement of the third fragment on fracture healing after intramedullary nailing of femoral shaft fractures with the third fragment. METHODS:A retrospective cohort study was conducted to analyze the clinical data of 142 patients suffered a femoral shaft fracture with a third fragment admitted to the Affiliated Lianyungang Hospital of Xuzhou Medical University from February 2016 to December 2021.The fracture were classified into three types according to the circumference of the third fracture with reference to the diaphyseal circumference at the fracture site:type 1 in 71 cases,type 2 in 52 cases,and type 3 in 19 cases.Referring to the diaphyseal diameter,the fractures were classified into three degrees according to the degree of the third fragment displacement:degree I in 95 cases,degree II in 31 cases,and degree III in 16 cases.All patients were treated with femoral interlocking intramedullary nails,and no intervention was performed for the displaced third fragment during the operation.Postoperative follow-up was performed to compare the fracture healing rate,healing time,and the modified Radiographic Union Scale for Tibia at month 9 after surgery in each group.The effect of third fracture fragment circumference and degree of displacement on fracture healing was assessed. RESULTS AND CONCLUSION:(1)All 142 patients were followed up for at least 12 months,with a mean of(14.7±4.1)months,and the overall healing rate was 73.4%.(2)When the third fragment was displaced by degree I,the healing rate,healing time,and modified Radiographic Union Scale for Tibia score at month 9 were not statistically significant among the three sub-groups of circumference classification.(3)When the third fragments were displaced by degree II or III,the healing rate and healing time were not statistically significant among the three subgroups of circumference classification;the modified Radiographic Union Scale for Tibia score at month 9 in the type 1 group was higher than that in the type 2 and 3 groups(P = 0.017).(4)Logistic regression analysis showed that a greater third fragment displacement and circumference were associated with lower fracture healing rates(P<0.05).(5)These findings indicate that in the treatment of femoral shaft fractures with third fragment by intramedullary nails,when the fracture fragment is displaced to degree I,the circumference size has little effect on fracture healing,and no intervention is required during surgery.When the third fragment is displaced to degree II or III and the circumference of which is type 1,a higher modified Radiographic Union Scale for Tibia score can still be obtained with no intervention of the third fragment.However,when the circumference is of type 2 or type 3,it significantly affects the fracture healing.Consequently,intraoperative intervention to reduce the distance of displacement of the fragment is required to lower the incidence of nonunion.The displacement of the third fracture fragments has a greater impact on fracture healing than their circumference.

		                        			Objective:To perform adenovirus detection and genetic evolutionary analysis on specimens from a fever outbreak in Kunming city.Methods:Pharyngeal swabs from typical febrile patients were collected and tested for nucleic acids of 30 common respiratory pathogens using TaqMan Array Card technology. The full-length sequences of three important genes of adenovirus, Penton base, Hexon and Fiber, were amplified, sequenced and typed using Nanopore high-throughput sequencing. A phylogenetic tree was constructed. Molecular variations and genetic evolution of the three genes were analyzed.Results:Five specimens were collected and all of them tested positive for adenovirus and Haemophilus influenzae. The sequences of the full-length coding regions of the Penton base, Hexon and Fiber genes were obtained by Nanopore sequencing. The homology of the three gene sequences in the five specimens was 100.0%, 99.9%-100.0% and 100.0% in nucleotide sequences, and 100.0% in amino acid sequences. The three genes in the specimens had the highest homology with those of the reference strain of human adenovirus type 3 (HAdV3, accession number: AY599834) in nucleotide sequences, which was 98.6%, 98.7% and 98.9%, respectively. Results of the phylogenetic analysis of the three genes were basically consistent. These Kunming strains were clustered into an independent clade with the reference HAdV3 strain and had a distant relationship with the strains isolated in foreign countries and Taiwan, China in the early years. They were closely related to the domestic and foreign strains in recent years and highly homologous to the 2019 Japanese strain (accession: LC703523) and the Guangzhou strain (accession: MZ540961). Compared with the reference strain, these Kunming strains had five amino acid variations in Penton base, 10 in Hexon and 11 in Fiber. Conclusions:All of the adenovirus strains isolated in this outbreak belong to P3H3F3 type based on the full-length sequences of Penton base, Hexon and Fiber genes. They share high homology with the domestic and foreign HAdV3 strains, including the reference strain. Compared with the reference strain, several amino acid mutations are identified in these Kunming strains, and most of them are in the high variability region or functional regions. M7L in the Hexon protein is an unique amino acid mutation site of Kunming strains.

		                        			Objective:To observe the rehabilitation effect of balance training relying on tilted table on diaphragmatic function of patients with prolonged disorder of consciousness (pDoC).Methods:A prospective study was performed. Thirty patients with pDoC were enrolled from Department of Hyperbaric Oxygen Medicine and Rehabilitation, General Hospital of Southern Theater Command of PLA from May to December 2023. The pateints were divided into study group ( n=15) and control group ( n=15) according to different rehabilitation. Patients from the control group received conventional rehabilitation, while those in the study group received passive balance training relying on tilted table in addition to conventional rehabilitation. Diaphragmatic ultrasound examination was performed before treatment, and 4 and 8 weeks after treatment to measure diaphragm excursion (DE), diaphragm thickening inspiration (DTei), diaphragm thickening expiration (DTee) and diaphragm thickening fraction (DTF) so as to assess the diaphragmatic functions of patients with pDoC. Results:During treatment, 2 patients dropped out from the study group resulting from the willing of the family members, ultimately including 13 and 15 patients in the study and control groups, respectively. (1) Between-group comparison: no significant difference in DE, DTei, DTee or DTF was noted between the study group and control group 4 weeks after treatment ( P>0.05). However, 8 weeks after treatment, the study group had statistically increased DE, DTei and DTF compared with the control group ([1.65±0.32] cm vs. [1.21±0.22] cm; [2.07±0.26] cm vs. [1.83±0.26] cm; and [24.39±3.19]% vs. [18.93±2.50]%). (2) Within-group comparison: both group had significantly increased DE 4 and 8 weeks after treatment compared with those before treatment ( P<0.05); in the study group, DE 8 weeks after treatment was significantly increased compared with that 4 weeks after treatment ( P<0.05). No significant difference in DTei, DTee or DTF was noted in both groups between 4 weeks after treatment and before treatment ( P>0.05). In the study group, DTei, DTee and DTF 8 weeks after treatment were significantly higher than those before treatment and 4 weeks after treatment ( P<0.05). Conclusion:Balance training relying on tilted table is feasible and effective in improving diaphragmatic function in patients with pDoC, and the effect is positively correlated with treatment time within a certain time.

		                        			 Objective To investigate the therapeutic effect of traditional Chinese medicine (TCM) on portal vein thrombosis (PVT) in patients with liver cirrhosis and its medication characteristics. Methods A retrospective analysis was performed for 89 patients with liver cirrhosis and PVT who were hospitalized and treated in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, and according to whether TCM treatment was applied in combination, they were divided into TCM group with 59 patients and control group with 30 patients. Related data were collected for the two groups, including demographic data, laboratory examination, radiological examination, gastroscopy, history of surgery, portal hypertension-related complications, medication, and follow-up data. The independent samples t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups. An ordinal polytomous Logistic regression analysis was used for multivariate analysis. TCM Inheritance Computing Platform (V3.0) was used to perform a drug effect cluster analysis of TCM prescriptions. Results The multivariate logistic regression analysis showed that esophageal and gastric varices (odds ratio [ OR ]=3.144, 95% confidence interval [ CI ]: 1.221-8.094), PVT involving the portal vein (PV) and the superior mesenteric vein (SMV) ( OR =51.667, 95% CI : 3.536-754.859), PVT involving PV+spleen vein (SV)+SMV ( OR =13.271, 95% CI : 2.290-76.928), cavernous transformation of the portal vein ( OR =11.896, 95% CI : 1.172-120.696), and TCM intervention ( OR =0.348, 95% CI : 0.129-0.938) were influencing factors for the outcome of PVT in liver cirrhosis. Follow-up results showed that compared with the control group, the TCM group had a significantly lower progression rate (16.95% vs 56.67%, P < 0.001) and a significantly lower incidence rate of variceal rupture and bleeding (8.47% vs 33.33%, P < 0.001). Effective TCM drugs with a relatively high frequency of use included deficiency-tonifying drugs (359 times, 34.6%), blood-activating and stasis-resolving drugs (202 times, 19.5%), and diuresis-inducing and dampness-draining drugs (180 times, 17.3%); the TCM drugs with a relatively high frequency of use included Astragalus membranaceus (57 times, 8.7%), Angelica sinensis (50 times, 7.6%), and leech (48 times, 7.3%); TCM drug combinations with a relatively high frequency of use included Astragalus membranaceus+Angelica sinensis, Astragalus membranaceus+leech, Angelica sinensis+leech, and Astragalus membranaceus+Angelica sinensis+leech. Conclusion Qi-tonifying, blood-activating, and stasis-breaking drugs, such as Astragalus membranaceus, Angelica sinensis, and leech, can promote the stabilization or recanalization of PVT in liver cirrhosis and reduce the incidence rate of bleeding events due to portal hypertension.

		                        			Objective:To evaluate the clinical value of NG-Test Carba5 for rapid detection of carbapenemases produced by carbapenem-resistant Enterobacteriaceae (CRE) strains. Methods:A total of 1 210 CRE strains were collected during 2018-2022 from 77 hospitals in 21 provinces of China and were subjected to NG-Test Carba5 for rapid detection of carbapenemase. The whole genome sequencing (WGS) analysis was referenced as the gold standard method.Results:Overall, the NG-Test Carba5 demonstrated excellent performance in detection of five kinds of carbapenemases [Klebsiella pneumoniae carbapenemase (KPC), New Delhi metallo-β-lactamase (NDM), imipenemase metallo-β-lactamase (IMP), Verona integron-encoded metallo-beta-lactamase (VIM) and oxacillinase-48-type carbapenemases(OXA-48)] from CRE strains, with a sensitivity of 98.47% (1 161/1 179), specificity of 100% (31/31), and positive predictive value of 100% (1 161/1 161). The sensitivity for detection of NDM, IMP, OXA and VIM reached 100% (307/307), and 97.70% (763/781) for KPC. For 11 strains carrying blaKPC-25, blaKPC-78, or blaKPC-93, NG-Test Carba5 reported positive KPC detection (11/11). For strains carrying blaKPC-33 and blaKPC-77, however, NG-Test Carba5 delivered negative results. Additionally, for those strains co-producing two or three kinds of carbapenemases, NG-Test Carba5 was able to report all of the targets with a sensitivity of 100% (91/91). Conclusions:NG-Test Carba5 showed excellent performance in rapid and accurate detection of carbapenemases from CRE strains. Nonetheless, for those strains with negative results, some other phenotypic and genotypic methods should be implemented alongside to avoid missing targets.

		                        			ObjectiveTo establish a set of single nucleotide polymorphisms (SNP) detection protocol for inbred rats based on multiplex PCR-ligase detection reaction (LDR). MethodsA total of 40 rats SNP sites were selected on chromosomes 1-20 and X of rats among 5 inbred strains of rats, and the 40 SNP sites were randomly divided into four groups. A genetic detection protocol for 4 groups of SNP in inbred rats based on multiplex PCR-LDR technology was constructed. 9 commonly used rat strains from two other domestic rat suppliers were detected by this protocol. Finally, the feasibility of this protocol was verified by comparing the amplification effects of different DNA polymerases by a third-party laboratory. ResultsWhen using the constructed SNP detection protocol for inbred rats to test 5 rat strains, all sites in each sample obtained good amplification results. The 9 commonly used rat strains from two other rat suppliers in china were also well amplified by this SNP detection protocol, and 40 SNPs were homozygous in each Inbred strain. The results of detection of the same rat DNA samples with three different DNA polymerases showed that the Multiplex PCR Kit, AmpliTaq Gold 360 DNA polymerase and Platinum II Taq hot start DNA polymerase had electrophoretic peaks of amplification products at all SNP sites in groups 1 to 3, and Platinum II Taq hot start DNA polymerase had one less electrophoretic peak of the amplification products at the SNP sites in group 4. In addition, inter-laboratory comparisons showed consistent results for the same amplification system. ConclusionBased on multiplex PCR-LDR technology, this study successfully established a SNP detection protocol for rats covering all autosomes and X chromosomes with the excellent stability and repeatability.

		                        			Objective:To explore the feasibility of early oral nutrition for gastric cancer patients after total gastrectomy based on propensity score matching.Methods:Using convenience sampling method, a retrospective analysis was conducted on the medical records of 755 patients who underwent total gastrectomy for gastric cancer at Jiangsu Subei People's Hospital from 2012 to 2020. A total of 454 patients who received early oral nutrition after surgery were included in the study group, while 301 patients who received conventional nutrition were included in the control group. The study group patients began eating orally on the first day after surgery, while the control group patients began eating orally after anal exhaust. The propensity score matching method was used to balance confounding factors between two groups.Results:A total of 203 pairs (406 cases) of patients were matched. After matching, there was no statistically significant difference in general data between the two groups ( P>0.05). The study group had lower dietary intake time, first anal exhaust time, hospital stay, incidence of abdominal infection, and incidence of anastomotic fistula compared to the control group, with statistically significant differences ( P<0.05) . Conclusions:Early oral nutrition for gastric cancer patients after total gastrectomy can promote intestinal function recovery, shorten hospital stay, and do not increase the risk of complications, including anastomotic fistula. It has the same acceptable tolerance as conventional nutrition, indicating that early oral nutrition after total gastrectomy is safe and feasible.

		                        			Multiple myeloma (MM) is still an incurable hematologic malignancy, which is eagerly to the discovery of novel therapeutic targets and methods. N-acetyltransferase 10 (NAT10) is the first reported regulator of mRNA acetylation that is activated in many cancers. However, the function of NAT10 in MM remains unclear. We found significant upregulation of NAT10 in MM patients compared to normal plasma cells, which was also highly correlated with MM poor outcome. Further enforced NAT10 expression promoted MM growth in vitro and in vivo, while knockdown of NAT10 reversed those effects. The correlation analysis of acetylated RNA immunoprecipitation sequencing (acRIP-seq) and ribosome profiling sequencing (Ribo-seq) combined with RIP-PCR tests identified centrosomal protein 170 (CEP170) as an important downstream target of NAT10. Interfering CEP170 expression in NAT10-OE cells attenuated the acceleration of cellular growth caused by elevated NAT10. Moreover, CEP170 overexpression promoted cellular proliferation and chromosomal instability (CIN) in MM. Intriguingly, remodelin, a selective NAT10 inhibitor, suppressed MM cellular growth, induced cellular apoptosis in vitro and prolonged the survival of 5TMM3VT mice in vivo. Collectively, our data indicate that NAT10 acetylates CEP1 70 mRNA to enhance CEP170 translation efficiency, which suggests that NAT10 may serve as a promising therapeutic target in MM.
