		                        			 Gegen Qinlian decoction has a wide range of clinical applications. However, there is a lack of systematic quality evaluation methods to ensure the safety and effectiveness of Gegen Qinlian decoction in clinical use. The UHPLC fingerprint and multi-component determination method of Gegen Qinlian decoction were established to provide scientific basis for the quality control and evaluation of Gegen Qinlian decoction. The chromatography was performed on a ZORBAX Eclipse Plus-C18 column (150 mm × 4.6 mm, 3.5 μm) with mobile phase consisted of acetonitrile (A) - 20 mmol·L-1 ammonium acetate (containing 0.8% acetic acid and 0.5% triethylamine) (B) and gradient elution at a flow rate of 1.0 mL·min-1. The column temperature was 25 ℃, the detection wavelength was 260 nm, the fingerprint of 10 batches of Gegen Qinlian decoction was determined, and the similarity evaluation system of TCM chromatographic fingerprint was used for comprehensive analysis, and 9 components were quantitatively analyzed. In the fingerprint study of Gegen Qinlian decoction, a total of 18 peaks were obtained, 12 of which were identified by reference substances. Moreover, the similarity of 10 batches of Gegen Qinlian decoction was good, and all of them were greater than 0.99. In the multi-component quantitative analysis, the linear relationship between the nine components and the peak area was good (

		                        			Based on network pharmacology and in vitro assays,we conducted a collaborative investi-gation into the protective effects of ginsenosides Rg1 and Re on LPS-induced damage of porcine je-junal epithelial cells IPEC-J2.Network pharmacology was used to obtain and screen the intersec-ting targets of Rg1 and Re to alleviate intestinal barrier damage,and molecular docking technique was used to verify the predicted results of network pharmacology.The experiment included the Control group,LPS group,Rg1 group,and Re group.The effects of different concentrations of Rg1 and Re on cell survival rate,apoptosis rate,TEER value,FD4 permeability,and inflammatory fac-tors of IPEC-J2 were observed,and the effects of different concentrations of Rg1 and Re on the mRNA expression levels of apoptosis-related genes were also detected by fluorescence quantitative PCR.The results of network pharmacology showed that the prevention of intestinal barrier damage by Rg1,Re mainly involved the processes of PI3K-Akt and MAPK signaling pathways.The molec-ular docking results showed that the binding energy of Rg1 to all intersecting targets was less than 0,while that of ginsenoside Re to SRC targets only was less than 0.In vitro experiments showed that pretreatment with different concentrations of Rg1 and Re increased the survival rate and TEER value of LPS-treated IPEC-J2 to varying degrees,and reduced the apoptosis,the decrease of FD4 permeability,and the secretion of inflammatory factor TNF-α,suggesting that Re and Rg1 prevented the intestinal barrier from damage.It was shown that Re and Rg1 could effectively re-duce the effects of LPS treatment on IPEC-J2 cells.Rg1 significantly upregulated the mRNA ex-pression levels of MAPK8,MAPK10,HRAS,and significantly down-regulated the mRNA expres-sion levels of MAP2K1,PIK3CG,IL-2 and SRC;and Re significantly upregulated the mRNA ex-pression levels of MAPK8,MAPK10,HRAS,and PIK3R1,BCL2 gene mRNA expression levels.These results suggest that ginsenosides Rg1,Re and ginsenoside products containing Rg1 and Re deserve further investigation in preventing intestinal barrier damage in piglets.

		                        			Objective: To understand the distribution of genotypes and sub-genotypes of HBV in different ethnic groups in China. Methods: The HBsAg positive samples were selected by stratified multi-stage cluster sampling from the sample base of national HBV sero-epidemiological survey in 2020 for the amplification of S gene of HBV by nested PCR. A phylogeny tree was constructed to determine the genotypes and sub-genotypes of HBV. The distribution of genotypes and sub-genotypes of HBV were analyzed comprehensively by using laboratory data and demographic data. Results: A total of 1 539 positive samples from 15 ethnic groups were successfully amplified and analyzed, and 5 genotypes (B, C, D, I and C/D) were detected. The proportion of genotype B was higher in ethnic group of Han (74.52%, 623/836), Zhuang (49.28%, 34/69), Yi (53.19%, 25/47), Miao (94.12%, 32/34), Buyi (81.48%, 22/27). The proportions of genotype C were higher in ethnic groups of Yao (70.91%, 39/55). Genotype D was the predominant genotype in Uygur (83.78%, 31/37). Genotype C/D were detected in Tibetan (92.35%,326/353). In this study, 11 cases of genotype I were detected, 8 of which were distributed in Zhuang nationality. Except for Tibetan, sub-genotype B2 accounted for more than 80.00% in genotype B in all ethnic groups. The proportions of sub-genotype C2 were higher in 8 ethnic groups, i.e. Han, Tibetan, Yi, Uygur, Mongolian, Manchu, Hui and Miao. The proportions of sub-genotype C5 were higher in ethnic groups of Zhuang (55.56%, 15/27) and Yao (84.62%, 33/39). For genotype D, sub-genotype D3 was detected in Yi ethnic group and sub-genotype D1 was detected in both Uygur and Kazak. The proportions of sub-genotype C/D1 and C/D2 in Tibetan were 43.06% (152/353) and 49.29% (174/353). For all the 11 cases of genotype I infection, only sub-genotype I1 was detected. Conclusions: Five genotypes and 15 sub-genotypes of HBV were found in 15 ethnic groups. There were significant differences in the distribution of genotypes and sub-genotypes of HBV among different ethnic groups.

		                        			Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage Ⅲ and 4 of stage Ⅳ. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.

		                        			Objectives: To examine the influence of adjuvant chemotherapy after radical resection on the survival of patients with intrahepatic cholangiocarcinoma(ICC) and to identify patients who may benefit from it. Methods: The clinical and pathological data of 654 patients with ICC diagnosed by postoperative pathology from December 2011 to December 2017 at 13 hospitals in China were collected retrospectively. According to the inclusion and exclusion criteria,455 patients were included in this study,including 69 patients (15.2%) who received adjuvant chemotherapy and 386 patients (84.8%) who did not receive adjuvant chemotherapy. There were 278 males and 177 females,with age of 59 (16) years (M(IQR))(range:23 to 88 years). Propensity score matching (PSM) method was used to balance the difference between adjuvant chemotherapy group and non-adjuvant chemotherapy group. Kaplan-Meier method was used to plot the survival curve,the Log-rank test was used to compare the difference of overall survival(OS) and recurrence free survival(RFS)between the two groups. Univariate analysis was used to determine prognostic factors for OS. Multivariate Cox proportional hazards models were then performed for prognostic factors with P<0.10 to identify potential independent risk factors. The study population were stratified by included study variables and the AJCC staging system,and a subgroup analysis was performed using the Kaplan-Meier method to explore the potential benefit subgroup population of adjuvant chemotherapy. Results: After 1∶1 PSM matching,69 patients were obtained in each group. There was no significant difference in baseline data between the two groups (all P>0.05). After PSM,Cox multivariate analysis showed that lymph node metastasis (HR=3.06,95%CI:1.52 to 6.16,P=0.039),width of resection margin (HR=0.56,95%CI:0.32 to 0.99,P=0.044) and adjuvant chemotherapy (HR=0.51,95%CI:0.29 to 0.91,P=0.022) were independent prognostic factors for OS. Kaplan-Meier analysis showed that the median OS time of adjuvant chemotherapy group was significantly longer than that of non-adjuvant chemotherapy group (P<0.05). There was no significant difference in RFS time between the adjuvant chemotherapy group and the non-adjuvant chemotherapy group (P>0.05). Subgroup analysis showed that,the OS of female patients,without HBV infection,carcinoembryonic antigen<9.6 μg/L,CA19-9≥200 U/ml,intraoperative bleeding<400 ml,tumor diameter>5 cm,microvascular invasion negative,without lymph node metastasis,and AJCC stage Ⅲ patients could benefit from adjuvant chemotherapy (all P<0.05). Conclusion: Adjuvant chemotherapy can prolong the OS of patients with ICC after radical resection,and patients with tumor diameter>5 cm,without lymph node metastasis,AJCC stage Ⅲ,and microvascular invasion negative are more likely to benefit from adjuvant chemotherapy.

		                        			This study aims to explore the mechanism of Qingkailing(QKL) Oral Preparation's heat-clearing, detoxifying, mind-tranquilizing effects based on "component-target-efficacy" network. To be specific, the potential targets of the 23 major components in QKL Oral Preparation were predicted by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and SwissTargetPrediction. The target genes were obtained based on UniProt. OmicsBean and STRING 10 were used for Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment of the targets. Cytoscape 3.8.2 was employed for visualization and construction of "component-target-pathway-pharmacological effect-efficacy" network, followed by molecular docking between the 23 main active components and 15 key targets. Finally, the lipopolysaccharide(LPS)-induced RAW264.7 cells were adopted to verify the anti-inflammatory effect of six monomer components in QKL Oral Preparation. It was found that the 23 compounds affected 33 key signaling pathways through 236 related targets, such as arachidonic acid metabolism, tumor necrosis factor α(TNF-α) signaling pathway, inflammatory mediator regulation of TRP channels, cAMP signaling pathway, cGMP-PKG signaling pathway, Th17 cell differentiation, interleukin-17(IL-17) signaling pathway, neuroactive ligand-receptor intera-ction, calcium signaling pathway, and GABAergic synapse. They were involved in the anti-inflammation, immune regulation, antipyretic effect, and anti-convulsion of the prescription. The "component-target-pathway-pharmacological effect-efficacy" network of QKL Oral Preparation was constructed. Molecular docking showed that the main active components had high binding affinity to the key targets. In vitro cell experiment indicated that the six components in the prescription(hyodeoxycholic acid, baicalin, chlorogenic acid, isochlorogenic acid C, epigoitrin, geniposide) can reduce the expression of nitric oxide(NO), TNF-α, and interleukin-6(IL-6) in cell supernatant(P<0.05). Thus, the above six components may be the key pharmacodynamic substances of QKL Oral Preparation. The major components in QKL Oral Prescription, including hyodeoxycholic acid, baicalin, chlorogenic acid, isochlorogenic acid C, epigoitrin, geniposide, cholic acid, isochlorogenic acid A, and γ-aminobutyric acid, may interfere with multiple biological processes related to inflammation, immune regulation, fever, and convulsion by acting on the key protein targets such as IL-6, TNF, prostaglandin-endoperoxide synthase 2(PTGS2), arachidonate 5-lipoxygenase(ALOX5), vascular cell adhesion molecule 1(VCAM1), nitric oxide synthase 2(NOS2), prostaglandin E2 receptor EP2 subtype(PTGER2), gamma-aminobutyric acid receptor subunit alpha(GABRA), gamma-aminobutyric acid type B receptor subunit 1(GABBR1), and 4-aminobutyrate aminotransferase(ABAT). This study reveals the effective components and mechanism of QKL Oral Prescription.

		                        			OBJECTIVES:
		                        			To explore the association between assisted reproductive technology (ART) and birth weight discordance in twins (BWDT).
		                        		
		                        			METHODS:
		                        			A retrospective analysis was conducted on twin infants born between January 2011 and December 2020 at the Third Affiliated Hospital of Guangzhou Medical University, with complete basic birth data. The impact of ART on the occurrence of BWDT was identified by the multivariate logistic regression analysis.
		                        		
		                        			RESULTS:
		                        			A total of 3 974 pairs of twins were included, with 1 431 conceived naturally and 2 543 through ART. Neonates in the ART group had higher birth weights than those in the naturally conceived group (P<0.001). The incidence of BWDT was lower in the ART group compared to the naturally conceived group (16.17% vs 21.09%, P<0.001). The multivariate logistic regression analysis, adjusting for confounding factors such as maternal age, parity, pre-pregnancy body mass index, gestational diabetes, hypothyroidism, gestational age, and chorionic properties, showed no significant difference in the risk of BWDT between the ART and naturally conceived groups (P>0.05).
		                        		
		                        			CONCLUSIONS
		                        			ART is not associated with the risk of BWDT.

		                        			Objective:To compare the long-term prognosis between open versus closed reduction and internal fixation in the treatment of unstable pelvic fractures.Methods:The data of 402 consecutive patients with unstable pelvic fracture were retrospectively analyzed who had been treated at The First Medical Center and The Fourth Medical Center, PLA General Hospital, and Strategic Support Force Specialty Medical Center from March 2011 to March 2017. This cohort was divided into 2 groups according to the reduction methods. In the open group of 194 cases subjected to open reduction and internal fixation, there were 133 males and 61 females with a median age of 43.0 (30.7, 51.0) years, and 35 cases of type B and 159 cases of type C by the Tile classification. In the closed group of 208 cases subjected to closed reduction and internal fixation, there were 115 males and 93 females with a median age of 45.5 (32.0, 56.0) years, and 40 cases of type B and 168 cases of type C by the Tile classification. The 2 groups were compared in terms of 12-items Short Form Health Survey (SF-12) scores [physical component summary (PCS) and mental component summary (MCS)] at the last follow-up, time from injury to operation, frequency of intraoperative X-ray fluoroscopy, intraoperative and postoperative blood transfusion, operation time, and quality of postoperative fracture reduction.Results:There was no statistically significant difference between the 2 groups in the preoperative general data except for the gender, showing the 2 groups were comparable ( P>0.05). This cohort of 402 patients was followed up for 7.8(6.2, 8.8) years. At the last follow-up, the PCS [49.9 (45.4, 55.4) points] and MCS [53.1 (46.4, 57.6) points] in the closed group were significantly higher than those in the open group [48.2 (41.4, 52.7) and 46.5 (40.6, 53.6) points] ( P<0.05). The closed group incurred significantly shorter time from injury to operation [6 (5, 8) d] and operation time [180 (126, 260) min] than the open group [9 (6, 13) d and 240 (165, 334) min], significantly less intraoperative and postoperative blood transfusion [1.5 (0, 4.0) U] than the open group [5.0 (2.9, 8.0) U], significantly higher frequency of intraoperative X-ray fluoroscopy [104.5 (85.0, 132.0) times] than the open group [21.0 (18.0, 26.0) times], and a significantly higher excellent and good rate of postoperative fracture reduction (92.8%, 193/208) than the open group (86.6%, 168/194) (all P<0.05). Conclusion:In the treatment of patients with unstable pelvic fractures, compared with open reduction and internal fixation, closed reduction and internal fixation can not only significantly shorten the waiting time and operation time of patients, reduce the transfusion during operation, but also achieve better fracture reduction to ultimately improve the quality of life of patients.

		                        			 Bitter almonds (Semen Armeniacae Amarum) are prone to oil deterioration during storage, so they often require mashing prior to clinical use. To confirm the medical value of bitter almonds "being mashed when used" and to determine the optimal storage conditions for bitter almonds, UPLC-MS/MS was used to perform a comparative study of the chemical composition of bitter almonds in different storage states (mashed and unmashed), storage times (0, 2 and 4 weeks), and storage temperatures (25 ℃ and 4 ℃). A total of 58 substances were identified in bitter almond extracts through literature review, this group's previous work, and a Compound Discoverer software search. Statistically significant differences were found in the chemical composition and content of bitter almonds in different storage states, storage times, and storage temperatures. The results show that the chemical composition of bitter almonds stored unmashed was more stable than that of bitter almonds stored mashed; the chemical composition of bitter almonds stored at 4 ℃ was more stable than that of bitter almonds stored at 25 ℃; and the shorter the storage time, the less the chemical composition changed. Amygdalin, the main medicinal component of bitter almonds, showed statistically significant differences in content under the above three storage conditions, which can be used as a potential quality marker for bitter almonds.
