ObjectiveTo investigate the clinical efficacy and safety of state-target formula Angelica and Safflower spot removal essence in the treatment of melasma. MethodsA randomized，double-blind，placebo-controlled parallel-group trial was conducted，selecting patients with Qi stagnation and blood stasis type of melasma who visited the dermatology outpatient department of Beijing Hospital of Integrated Traditional Chinese and Western Medicine from September 2022 to February 2023. In accordance with the double-blind principle，a random number table was generated to randomly divide the patients into an experimental group （50 cases） and a control group （50 cases）. The experimental group applied the Angelica and Safflower spot removal essence topically，while the control group applied a placebo topically，with continuous treatment for 8 weeks and a follow-up of 1 month. Melasma Area and Severity Index （MASI），Physician Global Assessment （PGA），patient self-assessment scoring，VISIA detection and scoring were performed before medication and on the first day after stopping medication，and all adverse events were recorded. ResultsIn a study involving 100 patients，87 cases were included in the analysis. The experimental group consisted of 45 cases，with 5 dropouts，and the control group had 42 cases，with 8 dropouts. The baseline data of the patients in both groups were consistent，with no statistically significant differences. After treatment，the total effective rate of the experimental group was 75.56% （34/45），significantly higher than the control group's 2.38% （1/42），and the difference was statistically significant （χ²=48.38，P<0.01）. Compared with before treatment，after treatment，the MASI score，VISIA image spot，brown spot，and red area score of the experimental group patients were significantly reduced （P<0.05，P<0.01），while there was no statistically significant difference in the control group patients. Compared with the control group after treatment，the experimental group showed more significant improvement （P<0.05，P<0.01）. VISIA image analysis showed that after 8 weeks of treatment，the experimental group showed significant improvement in surface spots，deep spots，and red areas，while the control group remained unchanged or showed an increasing trend. 42.22% （19/45） of the experimental group had a PGA score of 3 or below，while 88.89% （40/45） had a PGA score of 4 or below. 80.95% （34/42） of the control group had a PGA score of 5 or above，and the difference between the two groups was statistically significant （χ²=38.26，P<0.01）. There was no statistically significant difference in the recurrence rate and adverse reaction rate within one month between the experimental group and the control group. ConclusionThe state-target formula Angelica and Safflower spot removal essence is clinically effective and safe in the treatment of melasma.

OBJECTIVE: To compare the clinical efficacy of acupuncture with yin-yang regulation method versus local acupuncture in treating chronic low back pain (CLBP) in elderly patients with lumbar disc herniation (LDH), and to evaluate the changes in the multifidus muscle before and after treatment using musculoskeletal ultrasound. METHODS: A total of 128 elderly patients with CLBP due to LDH were randomly assigned to an observation group (64 cases, 2 cases dropped out) and a control group (64 cases, 2 cases dropped out). The control group received local acupuncture at bilateral L₃-L₅ Jiaji points (EX-B2), Shenshu (BL23), Dachangshu (BL25), Weizhong (BL40), Yaoyangguan (GV3), and ashi points. The observation group received acupuncture with yin-yang regulation method, which included an abdominal protocol with Baihui (GV20), Zhongwan (CV12), Qihai (CV6), Guanyuan (CV4), bilateral Tianshu (ST25), and Dahe (KI12), etc., and a lumbar protocol with Baihui (GV20), Dazhui (GV14), Jizhong (GV6), Yaoyangguan (GV3), and ashi points, etc., alternated bilaterally. Both groups were treated once every other day, three times per week, for a total of 12 sessions. The visual analogue scale (VAS) score, Oswestry disability index (ODI) score, and the indexs of musculoskeletal ultrasound multifidus muscle (resting and functional thickness and Young's modulus values) were observed before and after treatment, and the clinical efficacy was evaluated in the two groups. RESULTS: After 1 and 4 weeks of treatment, both groups showed lower VAS scores compared to baseline (P<0.05), the VAS scores in the observation group were lower than those in the control group (P<0.001). ODI scores in both groups were decreased after 1 and 4 weeks of treatment compared to baseline (P<0.05), with a further reduction at 4 weeks of treatment compared to 1 week of treatment (P<0.05); the observation group showed lower ODI score than the control group after 1 week of treatment (P<0.001). After treatment, both groups demonstrated increased resting and functional multifidus muscle thickness bilaterally compared to baseline (P<0.01), with an increased right-side thickness change rate (P<0.01), though no significant difference was observed between groups (P>0.05). Compared to baseline, after treatment, the observation group exhibited decreased Young's modulus values for bilateral resting and functional multifidus muscle (P<0.01), while the control group showed reductions only in bilateral resting and right-side functional Young's modulus values (P<0.01). After treatment, the bilateral functional Young's modulus values in the observation group were lower than that in the control group (P<0.05), and the bilateral resting and functional changes in Young's modulus values were greater in the observation group than those in the control group (P<0.01). The overall effective rate was 93.5% (58/62) in the observation group, which was higher than 79.0% (49/62) in the control group (P<0.05). CONCLUSION Acupuncture with yin-yang regulation method effectively alleviates pain, improves functional disability, increases multifidus muscle thickness, and reduces Young's modulus values in elderly patients with CLBP due to LDH, which has superior therapeutic effect compared to local acupuncture.

OBJECTIVE: To study incident and clinical characteristics of the coronary microcirculation dysfunction (CMD) in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI) by myocardial contrast echocardiography (MCE) and to explore the predictive value of CMD for in-hospital acute heart failure event. METHODS: One hundred and forty five patients with AMI who had received PCI and completed MCE during hospitalization in Peking University People' s Hospital from November 2015 to July 2021 were enrolled in our study. The patients were divided into CMD group and normal group according to the coronary microcirculation status detected by MCE. Clinical data and MCE data of the two groups were collected and analyzed. The acute heart failure event during hospitalization was described. A multivariate Logistic regression model was built to analyze the risk of acute heart failure in patients with CMD. A receiver operating characteristic (ROC) curve was drawn to evaluate the value of CMD in predicting acute heart failure event. RESULTS: CMD detected by MCE occurred in 87 patients (60%). Compared with normal group, patients with CMD had higher troponin I (TnI) peak level [52.8 (8.1, 84.0) μg/L vs. 18.9 (5.7, 56.1) μg/L, P=0.005], poorer Killip grade on admission (P=0.030), different culprit vessel (P < 0.001) and more patients had thrombolysis in myocardial infarction (TIMI) flow pre-PCI less than grade 3 in culprit vessel (65.1% vs. 43.1%, P=0.025). Meanwhile, patients with CMD had poorer left ventricular ejection fraction (LVEF) [52% (43%, 58%) vs. 61% (54%, 66%)], poorer global longitudinal strain (GLS) [-11.2% (-8.7%, -14.0%) vs.-13.9% (-10.8%, -17.0%)] and worse wall motion score index (WMSI) (1.58±0.36 vs. 1.25± 0.24) (P all < 0.001). Acute left heart failure happened in 13.8% of the CMD patients, which were significant higher than that in the patients with normal coronary microcirculation perfusion (1.7%, P=0.013). After correcting for the culprit vessel, the TIMI flow pre-PCI in the culprit vessel and the peak TnI value, the risk of acute left heart failure in the patients with CMD was still high (OR=9.120, 95%CI: 1.152-72.192, P=0.036). The area under ROC curve (AUC) was 0.677 (95%CI: 0.551-0.804, P=0.035). CONCLUSION The incidence of CMD detected by MCE in patients with AMI post-PCI was 60%. Patients with CMD have a higher risk of acute left heart failure during hospitalization.

Objective:Transcriptomics combined with proteomics was used to analyze the potential signaling pathways of epidermal growth factor-like domain 9 (EGFL9) affecting the proliferation, invasion and migration of hepatocellular carcinoma.Methods:RNA interference technique was used to build hepatocellular carcinoma cell line with EGFL9 Huh-7 gene knockdown, the control group (NC group) and experimental group (KD group), each group of three samples, were performed the transcriptome and proteomics analysis, screening differences genes and proteins, to express the correlation analysis, cluster analysis, and subsequently gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) were used for gene function and pathway annotation enrichment analysis, respectively.Results:Based on omics analysis, there were 8 335 different genes in KD group compared with NC group, among which 4 207 were up-regulated and 4 128 were down-regulated. There were 298 different proteins, of which 188 were up-regulated and 110 down-regulated. Based on the combined analysis of the two omics, 213 differentially expressed genes were found. Among them, the top three common differentially expressed genes at the level of transcription and translation were transferrin receptor 2 (TFR2), annexin A1 (ANXA1) and solute carrier family 38 member 2(SLC38A2). The common differentially expressed genes were significantly enriched in cell cycle signaling pathway, amino acid biosynthesis pathway, p53 signaling pathway and glycolysis/gluconeogenesis signaling pathway.Conclusion:EGFL9 may participate in the regulation of cell function of hepatocellular carcinoma cells by regulating the expression of TFR2, ANXA1, LC38A2 and other genes, and may play a role through the regulation of cell cycle and other molecular signaling pathways.

Background::Breast cancer is ranked among the most prevalent malignancies in the Chinese female population. However, comprehensive reports detailing the latest epidemiological data and attributable disease burden have not been extensively documented.Methods::In 2018, high-quality cancer surveillance data were recorded in 700 population-based cancer registries in China. We extracted data on female breast cancers (International Classification of Diseases, Tenth Revision [ICD-10]: C50) and estimated the incidence and mortality in 2022 according to the baseline data and corresponding trends from 2010 to 2018. Pathological types were classified according to the ICD for Oncology, 3rd Edition codes. Disability-adjusted life years (DALYs) were calculated as the sum of the years of life lost (YLLs) and years lived with disability (YLDs).Results::In 2022, approximately 357,200 new female breast cancer cases and 75,000 deaths occurred in China, accounting for 15.59% and 7.94% of total new cancer cases and deaths, respectively. The age-standardized incidence rate (ASIR) was 33.04 per 100,000. When analyzed by pathological type, the ASIRs for papillary neoplasms, invasive breast carcinoma, rare and salivary gland-type tumors, and other types were 1.13, 29.79, 0.24, and 1.88 per 100,000, respectively. The age-standardized mortality rate (ASMR) was 6.10 per 100,000. A total of 2,628,000 DALYs were found to be attributable to female breast cancer in China, comprising 2,278,300 YLLs and 349,700 YLDs. The ASIR, ASMR, and age-standardized rate (ASR) for DALYs in urban areas were consistently higher than those in rural areas. We observed a four-fold increase in the ASIR and ASR for DALYs and an eight-fold increase in the ASMR among females over 55 years compared with those aged under 55 years.Conclusion::These data provide invaluable insights into the latest epidemiology of female breast cancer in China and highlight the urgency for disease prevention and control strategy formulation.

Objective To investigate the risk factors of diabetic retinopathy(DR)in elderly patients with type 2 diabetes mellitus(T2DM)and establish the related prediction model.Methods A total of 426 elderly T2DM patients admitted to the Endocrinology Department of our hospital from January 2021 to March 2023 were enrolled in this study and divided into DR group(n=104)and T2DM group(n=322)according to the occurrence of DR.Results The DM duration≥10 years,hypertension,DPN,smoking,HbA1c,SUA,and high myopia were higher in the DR group than in the T2DM group(P<0.05).Pearson correlation analysis showed that DR was positively correlated with DM duration≥10 years,HbA1c,hypertension,DPN,smoking,SUA and high myopia in elderly T2DM patients(P<0.05).Logistic regression analysis showed that DM duration≥10 years,HbA1c,hypertension,DPN,smoking history,SUA,and high myopia were risk factors for DR in elderly T2DM patients.The analysis of the working characteristic curve of the subjects showed that the area under the curve for the occurrence of DR in elderly T2DM patients was 0.863,with a sensitivity of 78.8%and a specificity of 81.1%.Conclusions The duration of diabetes≥10 years,hypertension,DPN,smoking,HbA1c,SUA and high myopia are risk factors for the occurrence of DR in elderly patients with T2DM.The prediction model of DR has good accuracy in elderly patients with T2DM.

Objectives:To evaluate the impact of global longitudinal strain(GLS)for prognosis in ST-segment elevation myocardial infarction(STEMI)patients after percutaneous coronary intervention(PCI). Methods:We enrolled 156 STEMI patients who underwent PCI and spackle tracking imaging(STI)during hospitalization from September 2020 to August 2023.Patients with Killip Ⅱ-Ⅳ at baseline were excluded,138 patients were finally included.GLS was detected by STI.Patients were divided into more impaired group(GLS>-11.7%,n=57)and less impaired group(GLS≤-11.7%,n=81)according to Youden index.Clinical characteristics and echocardiography data were analyzed.Patients were followed up for a median of 21(13,28)months.Heart failure events were compared between the two groups. Results:The peak troponin I(TnI)was significantly higher in patients with GLS>-11.7%than those with GLS≤-11.7%at admission(85 160[31 297,214 226]pg/ml vs.34 942[13 571,92 713]pg/ml,P<0.001).Culprit vessel was different between the 2 groups(P<0.001).Compared with patients with GLS≤-11.7%,patients with GLS>-11.7%had lower left ventricular ejection fraction(LVEF)([60.1±8.7]%vs.[49.2±8.3]%,P<0.001),higher proportion of regional wall motion abnormality(90.1%vs.100%,P=0.015).Both LVEF and GLS recovered in patients with GLS>-11.7%during follow-up,but remained lower as compared to patients with GLS≤-11.7%(both P<0.001).The median follow-up time was 21(13,28)months.After adjusting age,sex,culprit vessel and peak TnI,the risk of heart failure of patients with GLS>-11.7%was significant higher(HR=9.123,95%CI:1.720-43.394,P=0.009). Conclusions:STEMI patients with more impaired GLS have a higher risk of heart failure post PCI.

BACKGROUND: Metastasis is the main cause of tumor-associated death and mainly responsible for treatment failure of breast cancer. Autophagy accelerates tumor metastasis. In our work, we aimed to investigate the possibility of microRNAs (miRNAs) which participate in the regulation of autophagy to inhibit tumor metastasis. METHODS: MiRNA array and comprehensive analysis were performed to identify miRNAs which participated in the regulation of autophagy to inhibit tumor metastasis. The expression levels of miR-3653 in breast cancer tissues and cells were detected by quantitative real-time polymerase chain reaction. In vivo and in vitro assays were conducted to determine the function of miR-3653. The target genes of miR-3653 were detected by a dual luciferase reporter activity assay and Western blot. The relationship between miR-3653 and epithelial-mesenchymal transition (EMT) was assessed by Western blot. Student's t -test was used to analyze the difference between any two groups, and the difference among multiple groups was analyzed with one-way analysis of variance and a Bonferroni post hoc test. RESULTS: miR-3653 was downregulated in breast cancer cells with high metastatic ability, and high expression of miR-3653 blocked autophagic flux in breast cancer cells. Clinically, low expression of miR-3653 in breast cancer tissues (0.054 ± 0.013 vs . 0.131 ± 0.028, t  = 2.475, P  = 0.014) was positively correlated with lymph node metastasis (0.015 ± 0.004 vs . 0.078 ± 0.020, t  = 2.319, P  = 0.023) and poor prognosis ( P  < 0.001). miR-3653 ameliorated the malignant phenotypes of breast cancer cells, including proliferation, migration (MDA-MB-231: 0.353 ± 0.013 vs . 1.000 ± 0.038, t  = 16.290, P  < 0.001; MDA-MB-468: 0.200 ± 0.014 vs . 1.000 ± 0.043, t  = 17.530, P  < 0.001), invasion (MDA-MB-231: 0.723 ± 0.056 vs . 1.000 ± 0.035, t  = 4.223, P  = 0.013; MDA-MB-468: 0.222 ± 0.016 vs . 1.000 ± 0.019, t  = 31.050, P  < 0.001), and colony formation (MDA-MB-231: 0.472 ± 0.022 vs . 1.000 ± 0.022, t  = 16.620, P  < 0.001; MDA-MB-468: 0.650 ± 0.040 vs . 1.000 ± 0.098, t  = 3.297, P  = 0.030). The autophagy-associated genes autophagy-related gene 12 ( ATG12 ) and activating molecule in beclin 1-regulated autophagy protein 1 ( AMBRA1 ) are target genes of miR-3653. Further studies showed that miR-3653 inhibited EMT by targeting ATG12 and AMBRA1 . CONCLUSIONS Our findings suggested that miR-3653 inhibits the autophagy process by targeting ATG12 and AMBRA1 , thereby inhibiting EMT, and provided a new idea and target for the metastasis of breast cancer.

Objective:To detect the expression of methyl methanesulfonate and UV sensitive gene clone 81 (Mus81) in hepatocellular carcinoma(HCC) and to observe the effects of Mus81 on the migration, invasion and metastatic ability of human HCC cells.Methods:Thirty-two tissue specimens were selected from HCC tissues and corresponding paraneoplastic tissues of patients with HCC who underwent surgical resection in Guangzhou Red Cross Hospital Affiliated to Jinan University from January 2020 to June 2021. The expression levels of Mus81 in 32 HCC specimens, 374 HCC samples from the cancer genome atlas database, human normal liver cell line HL-7702 and human HCC cell lines JHH-7, Huh-7 and Hep3B were analyzed. Mus81 knockdown in JHH-7, Huh-7 and overexpressed in Hep3B HCC cell lines were constructed, and the effects of Mus81 on HCC cells were observed by scratch assay, Transwell migration and invasion assay and tail vein injection transfer assay in nude mice.Results:The expression of Mus81 was higher in HCC tissues or cell lines than which in paraneoplastic tissues or normal hepatocyte lines (all P<0.05). The migration rate, metastatic and invasive cell numbers of Mus81-knockdown Huh-7 HCC cells were 22.24%±2.16%, 49.04±5.62, 3.81±1.08, the negative control group were 26.89%±1.15%, 86.81±4.79, 19.78±3.30, and the differences between the two groups were statistically significant ( t=4.24, 26.59, 23.92, all P<0.01). The migration rate, metastatic and invasive cell numbers of Mus81-overexpressed Hep3B HCC cells were 80.57%±5.12%, 18.74±8.07, 33.81±8.44, which were significantly higher than those of the empty vector group 64.17%±7.20%, 10.96±5.32, 3.04±1.13, and the differences were statistically significant ( t=4.15, 4.18, 18.78, all P<0.01). Tail vein transfer experiments in nude mice showed that the total fluorescence expression, weight of metastatic tumors, and the metastatic rates in kidney, vertebral column, neck, axilla and subcutis in nude mice injected with Mus81-knockdown JHH-7 cells were significantly lower than those in the control group (all P<0.05). Conclusion:Mus81 gene expression is upregulated in HCC and promotes the migration, invasion and metastatic ability of HCC cells, suggesting that Mus81 may be a potential therapeutic target for HCC.
