Objective:To investigate the relationship between key molecules of interleukin-6/signal transducer and activator of transcription 3 (IL-6/STAT3) signaling pathway and breast cancer susceptibility.Methods:A case-control study design was adopted. 136 patients with breast cancer admitted to Department of Breast Surgery, Yantai Yantaishan Hospital from Mar. 2021 to Mar. 2023 were selected as the case group, and 136 healthy subjects of the same age were matched as the control group in a 1:1 ratio. The clinical data and key molecules of IL-6/STAT3 signaling pathway were compared between the two groups. The risk factors of breast cancer susceptibility were evaluated by conditional Logistic regression and addition analysis, and the diagnostic efficiency of receiver operating characteristic curve (ROC) and area under curve (AUC) were plotted.Results:The body mass index (BMI) (22.21±0.68 vs. 21.30±0.70 kg/m 2), age at menarche (13.50±1.24 years vs. 14.83±1.42 years), IL-6 (3.50±1.05 vs. 2.41±0.74), Janus protein kinase 1 (JAK1) mRNA (1.23±0.36 vs. 0.88±0.26), STAT3 mRNA (1.68±0.50 vs. 1.17±0.35), and menopause (30.15% vs. 55.88%), breastfeeding (82.35% vs. 92.65%), physical exercise (44.12% vs. 58.09%) were significantly different between the case group and the control group ( t=10.87, 8.23, 9.89, 9.19, 9.75, χ2=18.37, 6.59, 5.31, P<0.05). Breastfeeding [odd ratio ( OR) : 0.550], interleukin-6 (IL-6) ( OR: 4.409), janus protein kinase 1 (JAK1) ( OR: 5.370) and signal transducer and activator of transcription 3 (STAT3) ( OR: 4.386) mRNAs were risk factors for breast cancer susceptibility ( P<0.05). ROC curve showed that the combined diagnostic efficacy of IL-6, JAK1, STAT3 mRNA in breast cancer was significantly better than that of a single diagnostic efficacy. The incidence rate of breast cancer in those who were exposed to IL-6 mRNA and breast feeding was 3.508 times higher than that in those who were not exposed. The incidence rate of breast cancer in those who were exposed to JAK1 mRNA and breast feeding at the same time was 4.136 times higher than that in those who were not exposed. The incidence rate of breast cancer in those who were exposed to STAT3 mRNA and breast feeding was 3.537 times higher than that in those who were not exposed. Conclusion:The key molecules of IL-6/STAT3 signaling pathway and breast-feeding are predisposing factors of breast cancer, and they have additive interaction, thus increasing the susceptibility of breast cancer, which has significant practical significance for the differential diagnosis and treatment of this disease.

ObjectiveTo observe the intervention effect of Chaihu and Longgu Mulitang （CLMT） on rat depression model prepared by chronic unpredictable mild stress （CUMS） based on cyclic adenosine monophosphate （cAMP）/protein kinase A （PKA）/cAMP-response element-binding protein （CREB）-brain-derived neurotrophic factor （BDNF） signaling pathway. MethodSixty SD rats were divided into normal group， model group， and CLMT low-， medium- and high-dose groups and fluoxetine group （positive control） according to random number table. They， except the normal group， were treated with CUMS for 49 days to prepare the rat depression model. The CLMT low-， medium- and high-dose groups were given 2.89， 5.78 11.56 g·kg^-1 of CHMD granules， respectively， and the fluoxetine group was given 2.06 mg·kg^-1 of fluoxetine hydrochloride on the 29^th day. The normal group and the model group received equal volume of normal saline for 21 days. The behavioral performance of rats were observed by open field test and forced swim test. The levels of 5-hydroxytryptamine （5-HT）， norepinephrine （NE） and cAMP in rat hippocampus were measured by enzyme-linked immunosorbent assay （ELISA）. The mRNA expressions of PKA， CREB， and BDNF in rat hippocampus were detected by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， and the protein expressions of PKA and BDNF were detected by Western blot. Immunohistochemistry was used to determine the expression of CREB， and hematoxylin and eosin （HE） staining and Nissl staining were used to observe the morphological changes of hippocampus. ResultCompared with the conditions in the normal group， the immobility time of the model group in the forced swim test was increased （P<0.01） and the total movement distance， residence time in central area， number of entries in central area and movement distance in central area were decreased （P<0.01）. Additionally， the contents of 5-HT， NE and cAMP in hippocampus of the model group as well as the protein expressions of PKA， BDNF and CRE，the mRNA expressions of BDNF and CREB were lower than those in the normal group （P<0.01）. Compared with the model group， the CLMT groups had reduced immobility time （P<0.01）， elevated total movement distance， residence time in central area， number of entries in central area and movement distance in central area （P<0.05， P<0.01）， up-regulated contents of 5-HT， NE and cAMP in hippocampus （P<0.05， P<0.01）， and up-regulated protein expressions of PKA， BDNF and CREB and mRNA expressions of BDNF and CREB （P<0.01）. HE staining and Nissl staining showed that CLMT significantly improved the neuronal structure in rat hippocampus. ConclusionCLMT alleviates the anxiety and depression of rats. These effects may be mediated by regulating monoamine neurotransmitters 5-HT and NE in hippocampus of depressed rats， activating cAMP/PKA/CREB/BDNF signaling pathway， up-regulating the expression of BDNF and protecting hippocampal structure and function .

Objective:To seek specific response points on the body surface of patients with primary dysmenorrhea(PD)by observing blood perfusion unit(PU)at different points of the three Yin meridians of foot using laser speckle contrast imaging(LSCI). Methods:Eighty PD patients were recruited as a PD group,and 80 healthy female undergraduates were taken as a normal group.During one menstrual cycle(before menstruation,during menstruation,and 3 d after menstruation),each participant was examined using the LSCI system to determine PU at bilateral Taixi(KI3),Taibai(SP3),Taichong(LR3),Shuiquan(KI5),Diji(SP8),Zhongdu(LR6),Sanyinjiao(SP6),and Xuehai(SP10)and non-acupuncture points.The researchers in charge of point location,operation,and statistical analysis were not aware of grouping.PU at the detection spots was taken as the outcome measure. Results:Compared with the normal group,the PD group showed increases in PU at right Taixi(KI3)before menstruation(P<0.05)and at bilateral Zhongdu(LR6)and right Diji(SP8)during menstruation(P<0.05).At the other time points,significance was not found between the two groups in comparing PU at the detected spots. Conclusion:Compared with healthy participants,PD patients present specific changes in PU at Taixi(KI3),Diji(SP8),and Zhongdu(LR6)at specific time points during the menstrual cycle,which provides a reference for acupuncture-moxibustion treatment of PD in clinical settings.

Nucleotide excision repair was a complex biochemical process that involved in the repair of many kinds of DNA damage. Previous study suggested that xeroderma pigmentosum group C (XPC) gene played an important role in the process of DNA damage repair. This study aimed to explore the influence of XPC gene polymorphism on the prognosis of patients with colorectal cancer (CRC) who were treated with capecitabine-related adjuvant chemotherapy. METHODS: A total of 158 patients with CRC who received surgical resection and capecitabine-based adjuvant chemotherapy were included in this study consecutively. Baseline clinical characteristics of patients were collected and analyzed. Additionally, peripheral blood specimens of the patients were collected for polymorphism analysis of XPC gene and mRNA expression of XPC, respectively. The association analysis between XPC polymorphism and prognosis and mRNA expression was performed. Cox regression analysis was used for multivariate adjustment. RESULTS: Prognostic data in the 158 patients with CRC who received capecitabine-based adjuvant chemotherapy was collected retrospectively. The median follow-up duration of the patients was 5.0 years (range: 0.25-7.5 years). The median DFS and OS of the 158 patients with CRC was 4.5 years and 5.7 years, respectively. XPC polymorphism analysis suggested that rs2228001 was of clinical significance. The prevalence of rs2228001 polymorphism among CRC patients was: TT genotype 86 cases (54.4%), TG genotype 60 cases (38.0%) and GG genotype 12 cases (7.6%), resulting in a minor allele frequency of 0.27, which was in accordance with Hardy-Weinberg equilibrium (P=0.733). TG and GG genotypes were merged in the subsequent analysis. The prognostic results exhibited that the median DFS of patients with TT genotype and TG / GG genotype was 4.5 and 5.7 years, respectively (c
