OBJECTIVES: To explore the rules of acupoint selection in the treatment of metabolic-associated fatty liver disease (MAFLD) with acupuncture and moxibustion by using data mining technology. METHODS: The clinical research literature on acupuncture treatment of MAFLD was collected from PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database, VIP Database and China Biology Medicine from their inception to November 20, 2022. According to our inclusion and exclusion criteria, the literature was independently screened and re-screened by two research members, and the screened results were checked, followed by establishing an acupoint prescription database using Excel 2019. Descriptive statistics of acupoints applied frequency, involved meridians, locations and specific acupoints were perpormed. Then, SPSS Modeler18.0 software was used to conduct analysis about association rules, and the SPSS Statistics 26.0 software was used to perform cluster analysis on high-frequency acupoints, exploring the characteristics and rules of acupoint selection and combination in the treatment of MAFLD. RESULTS: Totally, 178 papers were collected, containing 130 acupoints, with a total application frequency of 1 305. The top five acupoints are Zusanli (ST36), Fenglong (ST40), Ganshu (BL18), Taichong (LR3) and Sanyinjiao (SP6). The commonly involved meridians are the Stomach Meridian of Foot Yangming, Bladder Meridian of Foot Taiyang, and Spleen Meridian of Foot Taiyin. The employed acupoints are mostly located in the lower limbs and abdomen, and the five Shu acupoints and crossing acupoints are in the majority. The association rule analysis of high frequency acupoints indicated that of the 16 qualified acupoint groups, the top 5 with close correlation degrees are ST36 and ST40, ST36 and LR3, ST36 and SP6, ST40 and LR3 and ST36, ST36 and SP6 and ST40. Further, 3 effective clusters were obtained by cluster analysis. CONCLUSIONS: Acupuncture and moxibustion treatment of MAFLD follows the therapeutic principles of soothing the liver, invigorating the spleen, tonifying the kidney, and resolving phlegm and removing dampness. The core acupoint group is ST36, ST40 and LR3, and the combination of acupoints is based on syndrome differentiation. These results may provide a useful reference for clinical practice.

Research Trends of Acupuncture Therapy for Chronic Pain-Related Depression or Anxiety from 2003 to 2023: A Bibliometric Analysis.

Background: Chronic pain (CP) as a long-lasting stressor can often cause mood disorders, such as depression or anxiety. The comorbidity of CP and mood disorders poses challenges for treatment and increases healthcare costs. Acupuncture has emerged as a widely utilized approach to alleviate both CP and mood disorders. However, there is a lack of well-established bibliometric analyses in this area of research. Therefore, this study aimed to identify the current hotspots and research trends regarding the use of acupuncture for treating CP-related depression or anxiety. Methods: We searched the Web of Science Core Collection spanning from 2003 to 2023 to identify relevant literature about the use of acupuncture for treating CP-related depression or anxiety. Bibliometric and visualization analyses were performed using CiteSpace 5.7.R5 and Vosviewer 1.6.19 software. Results: A total of 254 articles published between 2003 and 2023 were included, revealing an upward trajectory with some fluctuations in publication numbers over the past two decades. China and the Beijing University of Chinese Medicine were the most productive country and institution in this field. Fang JQ and Vickers AJ ascended as the most prolific and influential authors, respectively. Trials was the journal with the highest number of publications, while Pain and BMJ-British Medical Journal exhibited the highest citation and centrality, respectively. "Acupuncture", "depression", and "chronic pain" were the top three keywords. The hotspots in this domain encompass types of chronic pain that predispose to negative mood, including fibromyalgia, irritable bowel syndrome (IBS), and neuropathic pain. Randomized controlled trials (RCTs), mechanisms, and evidence-based evaluations are the main research directions. Conclusion: This study uses bibliometric techniques to analyze the research hotspots and forefronts of acupuncture as a therapeutic approach for CP-related depression or anxiety. Our objective is to provide researchers with valuable references and identify research focal points for future investigations.

Surgery on primary melanoma of the breast.

Malignant melanoma of the breast (MMB) is a rare disease that accounts for 3-5% of all melanomas. It can be expressed as a metastatic mammary gland or primary mammary melanin of the mammary gland. Primary MMB (PMMB) can be divided into two types: parenchymal melanoma without skin involvement and melanoma involving skin on the breast. The diagnosis of PMMB relies mainly on histopathological diagnosis. In this diagnostic approach, S100 and HMB45 have a higher specificity in the diagnosis of melanoma immunohistochemistry. At the same time, mutations in the BRAF (V600E) gene have further aided the diagnosis of PMMB. After the diagnosis, the main treatment is mainly based on surgery. The main surgical methods include breast-conserving surgery and mastectomy. With advances in technology and surgical skills, the combination of patient aesthetic satisfaction and tumor safety is the goal of modern breast surgeons. This article reviews the current status of PMMB surgical treatment.

Macrocyclic compounds as anti-cancer agents: design and synthesis of multi-acting inhibitors against HDAC, FLT3 and JAK2.

A novel series of macrocyclic compounds were designed and synthesized as multi-target inhibitors targeting HDAC, FLT3 and JAK2. Some of these compounds exhibited potent HDAC inhibition as well as FLT3 and JAK2 inhibition under both cell-free and cellular conditions. In vitro antiproliferative assay indicated that these compounds were interestingly more cytotoxic to MV4-11 cells bearing FLT3-ITD mutation and HEL cells bearing JAK2(V617F) mutation.

Association between RECQL5 genetic polymorphisms and susceptibility to breast cancer.

Previous studies indicated that the RECQL5 gene polymorphism was associated with human cancers. However, the association of RECQL5 gene polymorphism with breast cancer remains unclear. In the present study, we investigated the association between polymorphisms of the RECQL gene and breast cancer in a Chinese population. We selected four polymorphisms of the RECQL5 gene (rs820186, rs820196, rs820200, and rs4789223) for the present study. The genotyping was performed using the TaqMan method in 510 patients with breast cancer and 510 age- and sex-matched non-cancer controls. We found that rs820196 and rs828200 polymorphisms of RECQL5 were associated with breast cancer. For rs820196, the CC genotype (16.7 vs 9.4 %, P < 0.001) and C allele (42.5 vs 34.3 %, P < 0.001) were common in the breast cancer patients than in the control subjects, respectively. For rs828200, the GG genotype (23.7 vs 18.0 %, P < 0.001) and G allele (52.7 vs 43.8 %, P < 0.001) were common in the breast cancer patients than in the control subjects, respectively. Haplotype analysis showed that C-G (odds ratio (OR) = 2.247, 95 % confidence interval (CI) 1.854∼2.722; P < 0.001) was associated with increased risk for breast cancer. However, the C-T (OR = 0.175, 95 % CI 0.110∼0.278; P < 0.001) and T-G (OR = 0.544; 95 % CI 0.428∼0.692; P < 0.001) were associated with decreased risk for breast cancer, respectively. The present study indicated that the RECQL5 genetic polymorphism and haplotypes were associated with breast cancer in a Chinese population.

Identification of differential proteins in colorectal cancer cells treated with caffeic acid phenethyl ester.

AIM: To investigate the molecular mechanisms of the anti-cancer activity of caffeic acid phenethyl ester (CAPE). METHODS: Protein profiles of human colorectal cancer SW480 cells treated with or without CAPE were analysed using a two-dimensional (2D) electrophoresis gel-based proteomics approach. After electrophoresis, the gels were stained with Coomassie brilliant blue R-250. Digital images were taken with a GS-800 Calibrated Densitometer, and image analysis was performed using PDQuest 2-D Analysis software. The altered proteins following CAPE treatment were further identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry following a database search. The identified proteins were validated by Western blot and immunofluorescence assay. RESULTS: CAPE induced human colorectal cancer cell apoptosis. Four up-regulated proteins and seven down-regulated proteins in colorectal cancer cells treated with CAPE were found. The identified down-regulated proteins in CAPE-treated colorectal cancer cells were Triosephosphate Isomerase (Tim), Proteasome subunit alpha 4 (PSMA4) protein, Guanine nucleotide binding protein beta, Phosphoserine aminotransferase 1 (PSAT1), PSMA1, Myosin XVIIIB and Tryptophanyl-tRNA synthetase. Notably, CAPE treatment led to the down-regulation of PSAT1 and PSMA1, two proteins that have been implicated in tumorigenesis. The identified up-regulated proteins were Annexin A4, glyceraldehyde-3-phosphate dehydrogenase, Glucosamine-6-phosphate deaminase 1 (GNPDA1), and Glutathione peroxidase (GPX-1). Based on high match scores and potential role in cell growth control, PSMA1, PSAT1, GNPDA1 and GPX-1 were further validated by Western blotting and immunofluorescence assay. PSMA1 and PSAT1 were down-regulated, while GNPDA1 and GPX-1 were up-regulated in CAPE-treated colorectal cancer cells. CONCLUSION: These differentiated proteins in colorectal cancer cells following CAPE treatment, may be potential molecular targets of CAPE and involved in the anti-cancer effect of CAPE.

[Research progresses of the PARP inhibitors for the treatment of cancer].

The poly(ADP-ribose) polymerases (PARPs) is an important group of enzymes in DNA repair pathways, especially the base excision repair (BER) for DNA single-strand breaks (SSBs) repair. Inhibition of PARP in DNA repair-defective tumors (like those with BRAC1/2 mutations) can lead to cell death and genomic instability, what is so called "synthetic lethality". Currently, PARP inhibitors combined with cytotoxic chemotherapeutic agents in the treatment of BRCA-1/2 deficient cancers are in the clinical development. In this review, we will be focused on the development of combination application of PARP inhibitors with other anticancer agents in clinical trials.

Surgical management of intestinal malrotation in adults.

OBJECTIVE: The aim of this study was to review our experience with diagnosis and surgical management of intestinal malrotation in adult patients. PATIENTS AND METHODS: A retrospective review of the surgical outcome of adults with intestinal malrotation was performed. Twelve patients were observed and treated between July 1996 and July 2006 (4 women and 8 men; the mean age of the patients was 28.5 years). Surgical outcomes, including postoperative complications, deaths, and resolution of preoperative symptoms, were measured. RESULTS: A diagnosis of malrotation was made preoperatively in five patients by upper gastrointestinal contrast study, barium enema, or computed tomography scan. The anomaly was discovered incidentally at laparotomy in seven patients. All cases were proved to be malrotation intraoperatively. Nine patients underwent laparotomy and three underwent laparoscopic surgery (one converted to an open procedure). Follow-up ranged from 2 months to 118 months. Three patients had complications: one had wound infection, one had delayed gastric emptying, and one developed adhesive ileus. There were only two recurrences detected and one patient with recurrence required reoperation. No one died. CONCLUSIONS: Intestinal malrotation is a rare but important cause of abdominal pain in adults. It may present with chronic or acute symptoms. Laparotomy and laparoscopy are alternative and feasible techniques with low rates of complications for the treatment of intestinal malrotation in adults.

Inhibitory effect of caffeic acid phenethyl ester on the growth of SW480 colorectal tumor cells involves beta-catenin associated signaling pathway down-regulation.

AIM: To study the anti-tumor effect of caffeic acid phenethyl ester (CAPE) and the influence of CAPE on beta-catenin associated signaling pathway in SW480 colorectal cancer (CRC) cells. METHODS: SW480 cells were treated with CAPE at serial concentrations. The proliferative status of cells was measured by methabenzthiazuron (MTT) assay. Cell cycle and cell apoptosis were analyzed using flow cytometry (FCM). Western blotting assay was used to evaluate the protein level of beta-catenin, c-myc and cyclinD1. Beta-catenin localization was determined by indirect immunofluorescence. RESULTS: CAPE displayed a strong inhibitory effect in a significant dose- and time-dependent manner on SW480 cell growth. FCM analysis showed that the ratio of G0/G1 phase cells increased, S phase ratio decreased and apoptosis rate increased after SW480 cells were exposed to CAPE for 24 h. Pretreatment of SW480 cells with CAPE significantly suppressed beta-catenin, c-myc and cyclinD1 protein expression. CAPE treatment was associated with decreased accumulation of beta-catenin protein in nucleus and cytoplasm, and concurrently increased its accumulation on the surface of cell membrane. CONCLUSION: CAPE can inhibit SW480 cell proliferation by inducing cell cycle arrest and apoptosis. Decreased beta-catenin and the associated signaling pathway target gene expression may mediate the anti-tumor effects of CAPE.

[Effects of p53 inhibitor-alpha on the proliferation and apoptosis in large intestinal epithelial cells damaged by hyperthermic chemotherapy].

OBJECTIVE: To investigate the effects of p-fifty three inhibitor-alpha (PFT-alpha), a p53 inhibitor, on the proliferation and apoptosis of colon epithelial cells damaged by hyperthermic chemotherapy. METHODS: Normal epithelial cells were obtained from the mucosa at least 10 cm away from the cancer tissue in a specimen of large intestine cancer resected during operation and cultured. PFT-alpha at different concentrations was added into the culture fluid to observe its effects on the proliferation of the epithelial cells. Epithelial cell in logarithmic growth phase were inoculated in 6-well plate and divided into 3 groups: normal control (CON) group; hyperthermic chemotherapy (HTC) group, undergoing treatment of cisplatin and bath in water at 43 degrees C; and PFT-alpha + HTC group, undergoing treatment of PFT-alpha at different concentrations, cisplatin, and warm water bath. The cell apoptosis was observed by annexin V-fluorescein isothiocyanate/propidium iodide (PI) staining and flow cytometry (FCT). The cell cycle was observed by PI staining and FCT. Western blotting was used to detect the protein expression of cyclinB1 and Cdc2, and RT-PCR was used to detect the mRNA expression of cyclinB1. RESULTS: PFT-alpha at the concentration > 60 micromol/L significantly inhibited the proliferation of the large intestine epithelial cells. The natural apoptosis rate of the large intestine epithelial cells (CON group) was 2.9% +/- 0.4%, the apoptosis rate was 27.0% +/- 2.1% in the HTC group, and the apoptosis rates of the PFT-alpha + HTC group were 14.8% +/- 1.5%, 9.7% +/- 1.2%, 6.1% +/- 1.3%, and 3.8% +/- 0.3%, on a downward trend, corresponding to the increase of PFT-alpha concentration from 0, 20, 30, to 40 micromol/L (all P < 0.05). The G(0)/G(1) phase rate of epithelial cells was higher and the S phase rate was lower significantly in the PFT-alpha + HTC group. The G(2)/M phase rate was higher since the PFT-alpha concentration reached 10 micromol/L and then increased along with the increase of the PFT-alpha concentration; the S phase rates of the PFT-alpha + HTC group with different PFT-alpha concentrations were all significantly higher than that of the HTC group (all P < 0.01), however, were still lower than that of the CON group (all P < 0.01). The protein expressions of cyclinB1 and Cdc2 in the PFT-alpha + HTC group were both significantly higher than those in the CON and HTC groups (all P < 0.01), without a significant difference between the latter 2 groups. The mRNA expression of cyclinB1 in the PFT-alpha + HTC group increased along with the increase of the PFT-alpha concentration, and there wee significant differences in the mRNA expression of cyclinB1 between the CON and PFT groups and PFT-alpha + HTC group with the PFT-alpha concentration > or = 10 micromol/L (P < 0.05 or P < 0.01). CONCLUSION: PFT-alpha dose-dependently protects the hyperthermic chemotherapy-induced damage to the large intestine epithelial cells via upregulation of protein and mRNA expression of cyclinB1, increasing the phosphorylation level of Cdc2, decreasing the cyclinB1/Cdc2 activity, and increasing the G(2)/M phase rate of the cells.

Effect of caffeic acid phenethyl ester on proliferation and apoptosis of colorectal cancer cells in vitro.

AIM: To study the effect of caffeic acid phenethyl ester (CAPE) on proliferation, cell cycle, apoptosis and expression of beta-catenin in cultured human colorectal cancer (CRC) cell line HCT116. METHODS: HCT116 cells were treated with CAPE at serial concentrations of 80, 40, 20, 10, 5, 2.5 mg/L. The proliferative status of HCT116 cells was measured by using methabenzthiazuron (MTT) assay. Cell cycle was analyzed by using flow cytometry (FCM) with propidium iodide (PI) labeling method. The rate of apoptosis was detected by using FCM with annexin V-FITC and PI double labeling method. beta-catenin levels were determined by Western blotting. beta-catenin localization in HCT116 was determined by indirect immunofluorescence. RESULTS: After HCT116 cells were exposed to CAPE (80, 40, 20, 10, 5, and 2.5 mg/L) for 24, 48, 72, 96 h, CAPE displayed a strong growth inhibitory effect in a dose- and time-dependent manner against HCT116 cells. FCM analysis showed that the ratio of G(0)/G(1) phase cells increased, S phase ratio decreased and apoptosis rate increased after HCT116 cells were exposed to CAPE (10, 5, and 2.5 mg/L) for 24 h. CAPE treatment was associated with decreased cytoplasmic beta-catenin, nuclear beta-catenin and a concurrent increase in beta-catenin protein expression at cell-cell junctions. CONCLUSION: CAPE could inhibit HCT116 cell proliferation and induce cell cycle arrest and apoptosis. Decreased beta-catenin protein expression may mediate the anti-proliferative effects of CAPE.

Regulatory effect and mechanism of gastrin and its antagonists on colorectal carcinoma.

AIM:To explore the effect and mechanism of gastrin and its antagonists prog lumide and somatostatin on colorectal carcinoma and their clinical significance.METHODS:A model of transplanted human colonic carcinoma was established from SW480 cell line in gymnomouse body.The volume and weight of transplanted carcinoma was observed under the effect of pentagatrin (PG), proglumide (PGL) and octapeptide somotostatin (SMS201-995, SMS). The cAMP content of carcinoma cell was determined by radioimmunoassay and the DNA, protein content and cell cycle were determined by flow-cytometry. The amount of viable cells was determined by MTT colorimetric analysis,IP(3) content was determined by radioimmunoassay, Ca(2+) concentration in cell by fluorometry and PKC activity by isotopic enzymolysis. The expression of gastrin, c-myc, c-fos and rasP21 in 48 cases of colorectal carcinoma tissue was detected by the immuno-cytochemistry SP method. Argyrophilia nucleolar organizer regions was determined with argyrophilia stain.RESULTS:The volume,weight, cAMP, DNA and protein content in carcinoma cell, cell amount and proliferation index of S and G(2)M phase in PG group were all significantly higher than those of control group. When PG was at the concentration of 25mg/L, the amount of viable cells, IP(3) content and Ca(2+) concentration in cell and membrane PKC activity in PG group were significantly higher than those in control group; when PGL was at a concentration of 32mg/L, they dropped to the lowest level in PG (25mg/L)+PGL group, but without significant difference from the control group. The positive expression rate of gastrin, c-myc, c-fos and rasP21 in carcinoma tissue was 39.6%, 54.2%, 47.9% and 54.2% respectively and significantly higher than that in mucosa 3cm and 6cm adjacent to carcinoma tissue and normal colorectal mucosa. The positive expression rate of gastrin of highly differentiated adenocarcinoma group was significantly higher than that of poorly differentiated and mucinous adenocar-cinoma groups. The AgNORs count of carcinoma tissue was significantly higher than that in mucosa 3cm and 6cm adjacent to carcinoma tissue and normal colorectal mucosa; and the positive expression of c-myc and c-fos and the AgNORs count in gastrin-positive group was significantly higher than those in gastrin negative group.CONCLUSION:Pentagastrin has a promoting effect on the growth of transplanted human colonic carcinoma from SW480 cell line. PGL has no obvious effect on the growth of human colonic carcinoma SW480 cell line, but could inhibit the growth promoting effect of PG on transplanted carcinoma. Somatostatin can not only inhibit the growth of transplanted human colonic carcinoma from SW480 cell line directly but also depress the growth-promoting effect of gastrin on the transplanted carcinoma. Some colorectal carcinoma cells can produce and secrete gastrin through autocrine, highly differentiated adenocarcinoma express the highest level gastrin.Endogenous gastrin can stimulate the cell division and proliferation of carcinoma cell and promote the growth of colorectal carcinoma regulating the expression of oncogene c-myc, c-fos. Our study has provided experimental basis for the adjuvant treatment using gastrin antagonist such as PGL, somatostatin of patients with colorectal carcinoma.
