Aim To observe the effects of Wenfei Jiangzhuo formula(WFJZF)on rats with vascular de-mentia and investigate its possible mechanism of ac-tion.Methods Thirty-six healthy male SD rats were randomly divided into the sham group,model group,donepezil group,and low-dose,medium-dose and high-dose groups of Wenfei Jiangzhuo formula,with six rats per group.Except for the sham group,the other groups were prepared as VaD models,and each group was gavaged with the corresponding drugs after suc-cessful modeling,and tests were performed after three weeks of treatment.Behavioral,hippocampal CA1 area morphology,neural dendrites and mitochondrial chan-ges were observed in all groups of rats,and phospho-glycerate mutase 5(PGAM5),dynamics-related pro-teins1(Drp1),opticatrophyprotein-1(OPA1),and other proteins were detected in each group.Results Compared with the sham group,rats in the model group and each intervention group had prolonged es-cape latency(P＜0.05),a shorter number of travers-als across the platforms(P＜0.05),a sparse morphol-ogy of hippocampal neurons,a reduction in the number of secondary dendritic spines,and a rupture of the out-er membrane of the mitochondria;the expression of the PGAM5 and Drp1 proteins in hippocampal tissues was elevated(P＜0.05),and the expression of the OPA1 and Mfn1/2 protein expression decreased(P＜0.05);compared with the model group,donepezil group and Wenfei Jiangzhuo formula high-dose group of rats had shorter evasion latency(P＜0.05),increased number of times to traverse the platform(P＜0.05),increased number of hippocampal neurons,tightly packed,more secondary dendritic structures,and reduced mitochon-drial damage;the expression of PGAM5 and Drp1 pro-teins was reduced(P＜0.05),and the expression of OPA1 and Mfn1/2 proteins was elevated(P＜0.05).Conclusions Wenfei Jiangzhuo formula can regulate the PGAM5-Drp1 signaling axis to improve the balance of mitochondrial homeostasis,thus improving the cog-nitive condition of the brain and exerting cerebroprotec-tive effects.

BACKGROUND: Currently, more and more infertility couples are opting for combined acupuncture to improve success rate of in vitro fertilization (IVF). However, evidence from acupuncture for improving IVF pregnancy outcomes remains a matter of debate. OBJECTIVE: To quantitatively summarized the evidence of the efficacy of acupuncture among women undergoing IVF by means of systematic review and meta-analysis. METHODS: Four English (PubMed, Web of Science, EMBASE, and Cochrane Register of Controlled Clinical Trials) and Four Chinese databases (Wanfang Databases, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, and SinoMed) were searched from database inception until July 2, 2023. Randomized controlled trials (RCTs) that evaluated the acupuncture's effects for women undergoing IVF were included. The subgroup analysis was conducted with respect to the age of participants, different acupuncture types, type of control, acupuncture timing, geographical origin of the study, whether or not repeated IVF failure, and acupuncture sessions. Sensitivity analyses were predefifined to explore the robustness of results. The primary outcomes were clinical pregnancy rate (CPR) and live birth rate (LBR), and the secondary outcomes were ongoing pregnancy rate and miscarriage rate. Random effects model with I² statistics were used to quantify heterogeneity. Publication bias was estimated by funnel plots and Egger's tests. RESULTS: A total of 58 eligible RCTs representing 10,968 women undergoing IVF for pregnant success were identifified. Pooled CPR and LBR showed a signifificant difference between acupuncture and control groups [69 comparisons, relative risk (RR) 1.19, 95% confifidence intervals (CI) 1.12 to 1.25, I²=0], extremely low evidence; 23 comparisons, RR 1.11, 95%CI 1.02 to 1.21, I²=14.6, low evidence, respectively). Only transcutaneous electrical acupoint stimulation showed a positive effect on both CPR (16 comparisons, RR 1.17, 95%CI 1.06 to 1.29; I²=0, moderate evidence) and LBR (9 comparisons, RR 1.20, 95%CI 1.04 to 1.37; I²=8.5, extremely low evidence). Heterogeneity across studies was found and no studies were graded as high-quality evidence. CONCLUSION Results showed that the convincing evidence levels on the associations between acupuncture and IVF pregnant outcomes were relatively low, and the varied methodological design and heterogeneity might inflfluence the fifindings.

[ Abstract] Objective To explore the role pathway and pattern of the Kruppel-like factor 4 (KLF4) and its mRNA interaction with microRNA (miRNAs) and circular RNA (circRNAs) at 0 hour and the 120 th hour in the rat liver regeneration. Methods The rat 2 / 3 hepatectomy (partial hepatectomy, PH) model was prepared as described by Higgins, the hepatocytes were isolated according to the method of Smedsrod et al, the expression changes of mRNA, miRNA and circRNA together named as competing endogenous RNA (ceRNA) were detected by the large-scale quantitative detection technology, the interaction network of ceRNA was constructed by Cytoscape 3. 2 software, and their correlation in expression and role were analyzed by ceRNA comprehensive analysis. Results It was found that at the 0 hour and the 120th hour PH, the ratio value of KLF4 mRNA showed 1. 00±0. 16 and 3. 14±0. 27, miR-881-3p displays 18. 30±1. 44 and 0. 47±0. 02, circRNA_20298 indicated 0. 32±0. 10 and 4. 24±0. 22, circRNA_14826 showed 0. 42±0. 13 and 0. 61±0. 08. At the same time, the four kinds of cell apoptosis-related genes adrenoceptor beta 2 (ADRB2), dimethylarginine dimethylaminohydrolase 2 (DDAH2), annexin A5 (ANXA5), ect, which were promoted in expression by KLF4, were down-regulated at 0 hour after PH, but the cell apoptosis-related genes synuclein gamma (SNCG), glutathione-disulfide reductase (GSR), FYVE, RhoGEF and PH domain containing 4 (FGD4), ect, which were inhibited in expression by KLF4, were up-regulated at 0 hour after PH. On the other hand, the cell apoptosis-related genes ANXA5 and thymosin beta 10 (TMSB10), which are promoted in expression by KLF4, were up-regulated at the 120th hour after PH, but the cell apoptosis-related genes chloride intracellular channel 4 (CLIC4) and ataxin 3 (ATXN3), ect, which were inhibited in expression by KLF4, were down-regulated at the 120th hour after PH. Conclusion The correlation in expression and role of the miRNAs, which are inhibited by circRNAs, KLF4, its mRNA is inhibited by miRNAs, and the cell apoptosis-related genes, which are regulated by KLF4, are helpful for the hepatocyte to be in active state 0 hour after PH and to be in apoptotic state 120-hour after PH.

This study was to investigate the diagnostic value of the computed tomography (CT) histogram in thyroid benign solitary coarse calcification nodules (BSCNs). A total of 89 thyroid solitary coarse calcification nodules (coarse calcification ≥5 mm, no definite soft tissue around calcification) confirmed either by surgery or histopathological examination in 86 cases enrolled from January 2009 to December 2015 were evaluated. These included 56 BSCNs and 33 malignant solitary coarse calcification nodules (MSCNs). Overall, 27 cut-off values were calculated by N (4≤N≤30) times of 50 Hounsfield units (HU) in the range of 200 to 1500 HU, and each cut-off value and the differences in the corresponding area percentages in the CT histogram were recorded for BSCN and MSCN. The optimal cut-off value and the corresponding area percentage were established by receiver operating characteristic (ROC) curve analysis. In the 19 groups with an ROC area under curve (AUC) of more than 0.7, at a cut-off value of 800 HU and at an area percentage of no more than 93.8%, the ROC AUC reached the maximum of 0.79, and the accuracy, sensitivity, and specificity were 75.3%, 80.4%, and 66.7%, respectively. At a cut-off value of 1050 HU and at an area percentage of no more than 93.6%, the accuracy, sensitivity, and specificity were 71.9%, 60.7%, and 90.9%, respectively. At a cut-off of 1150 HU and area of no more than 98.4%, the accuracy, sensitivity, and specificity were 70.8%, 57.1%, and 93.9%, respectively. At a cut-off of 600 HU and area of no more than 12.1%, the accuracy, sensitivity, and specificity were 61.8%, 39.3%, and 100.0%, respectively. Compared with the cut-off value of 800 HU and an area percentage of no more than 93.8%, the sensitivity of cut-off values and minimum areas of 1050 HU and 93.6%, of 1150 HU and 98.4%, and of 600 HU and 12.1%, was gradually decreasing; however, their specificity was gradually increasing. This can provide an important basis for reducing the misdiagnosis and unnecessary surgical trauma.

OBJECTIVEThe aim of this study was to investigate the relationship of the mutations of leptin receptor gene exon 4, exon 6, exon9, and exon20 with the tumorigenesis of breast cancer.

METHODSGenomic DNA was extracted from breast cancer tissues of 155 patients, benign lesions of 56 patients and normal tissues and blood samples from 100 health control subjects. The leptin receptor genes were assayed with polymerase chain reaction (PCR) amplification and direct sequence analysis.

RESULTSNucleotide substitutions no mutations were found at exon 4, and nucleotide substitutions occurred at codon 1029 in exon 9, no significant difference among the three groups (P = 0.574). The nucleotide substitutions at codon 668 in exon 6 resulted in Gln223Arg polymorphisms. The occurring frequencies of GG, GA, AA in breast cancer, breast benign lesions tissues and health tissues control group were 70.9% and 17.4%, 12.3%; 80.4%, 14.3% and 5.4%; and 81.0%, 16.0%, and 3.0%, respectively. Alleles of G and A in the three groups were 79.1% and 20.8%, 87.5% and 12.5%, and 89.0% and 11.0%, respectively. Compared the Gln223Arg genotype with the three allele groups, there were significant differences (χ(2) = 16.11, P < 0.005 and χ(2) = 11.41, P < 0.01), respectively. The nucleotide substitutions at codon 3057 in exon 20 resulted in Pro1019Pro polymorphisms. The occurrence frequencies of GG, GA, AA in the breast cancer, benign disease and health control groups were 11.6%, 30.3% and 56.1%; 32.1%, 44.0% and 28.5%; and 32.0%, 45.0% And 23.0%, respectively. Alleles of G and A in the three groups were 26.8% and 73.2%, 51.8% and 48.2%, and 54.5% and 45.5%, respectively. There are significant differences among the three groups (χ(2) = 6.56, P < 0.03 and χ(2) = 5.45, P < 0.05), respectively. Nucleotide substitutions occurred at relatively high frequencies at exon 6 and exon 20 in obese and overweight breast cancer patients compared with those in normal weight breast cancer patients, there were significant differences (P < 0.05 and P < 0.01).

CONCLUSIONSOur findings show that there is no relationship between the variations of leptin receptor gene exon 9 and tumorigenesis of breast cancer. The variation rate of leptin receptor gene exon 6 and exon 20 are significantly increased in the obese and overweight breast cancer patients.

BACKGROUNDBlood coagulation factor VII (FVII) is physiologically synthesized in the liver and released into the blood. Binding of FVII to tissue factor (TF) is related to the metastatic potential of tumor cells, also a significant risk factor in the development of hepatic metastasis in patients with colorectal cancer (CRC). It has been found that some cancer cells can produce FVII extrahepatically. However, little is known about FVII and CRC. We therefore hypothesized that CRC cells may synthese FVII, leading to tumor invasion and metastasis.

METHODSWe detected the expression of FVII protein in 55 CRC specimens by immunohistochemical staining. The FVII mRNA in 45 of 55 CRC cases, 6 colon cancer cell lines and one hepatoma cell line was measured by real-time reverse transcription-PCR (RT-PCR). Transwell invasion assays were performed to evaluate the changes of cell migration and invasion of LoVo cancer cells in vitro. We further observed the likely effectors regulated by the TF/FVIIa complex Western blotting assay.

RESULTSExtrahepatic synthesis of FVII was detected in the cytoplasm of 32 (58.2%) CRC specimens by immunohistochemistry, but not in normal mucosa. Liver metastasis (P = 0.003) and TNM staging (P = 0.005) were significantly correlated with FVII antigen expression. The positive ratios in stages I, II, III and IV were 33.3%, 40.0%, 52.4% and 87.5%, respectively. The expression of FVII mRNA in CRC with hepatic metastasis was significantly higher than CRC without hepatic metastasis (5.33 ± 2.88 vs. 1.47 ± 0.51, P = 0.03). Ectopic FVIIa induced a slight increase (1.34-fold) in the number of migrating cells, which was inhibited by the specific TF antibody. The formation of TF/FVIIa complex resulted in a marked increase in the expression of matrix metalloproteinases (MMP)-2 (3.5-fold) and MMP-9 (4.7-fold) in a time-dependent and dose-dependent manner.

CONCLUSIONSExtrahepatic synthesis of FVII by CRC cells may promote tumor invasion and metastasis. MMPs, as downstream effectors of TF/FVIIa signaling, facilitate the development of metastasis in colon cancer.

OBJECTIVETo study the different features of hyperplasia in castrated and uncastrated mice after testosterone (T) treatment.

METHODSForty-eight BALB/c mice were randomly divided into 6 groups of 8 in each: castrated (A), uncastrated (B) , castrated + low T (C), uncastrated + low T (D), castrated + high T (E), uncastrated + high T (F). Groups C and D were treated with testosterone solution at the dose of 12.5 mg/(kg d) and Groups E and F at 125 mg/(kg d) for 20 consecutive days, while Groups A and B received saline only. All the mice were sacrificed on the 21st day, their ventral and dorsal prostate glands weighed and their pathological features studied.

RESULTSAtrophic prostates were observed in Group A, but normal in Group B; prostatic hyperplasia was found in both Group C and D, but more obvious in the latter (P <0.05); and a slightly higher degree of hyperplasia was noted in Groups E and F than in C and D. There was an increase in serum T and vascular endothelial growth factor (VEGF) concentration and a decrease in serum estrogen (E2) concentration in the testosterone treated groups.

CONCLUSIONBoth castrated and uncastrated mice develop prostate hyperplasia after short-term testosterone treatment, although in different degrees and with different features, which may help further the studies on the association of castration and androgen with prostate diseases.

OBJECTIVETo evaluate the expression and clinical significance of urinary nuclear matrix protein (NMP22) and cytokeratin 18 (CK18) for transitional cell carcinoma of the bladder.

METHODSUrinary NMP22 and CK18 levels of 293 patients with transitional cell carcinoma of the bladder, 400 patients with non-transitional cell carcinoma of the bladder, and 105 bladder benign disease were analysed by enzyme-linked-immunosorbent assay (ELISA).

RESULTSThe levels of urinary NMP22 and CK18 in the patients with transitional cell carcinoma of the bladder (M = 17.3 U/ml, M(CK18) = 484.2 U/L) were significantly higher than those in the non-transitional cell carcinoma of the bladder (M = 6.8 U/ml, M(CK18) = 156.0 U/L) and the benign disease group (M(NMP22) = 2.3 U/ml, M(CK18) = 66.6 U/L) (P < 0.001). The sensitivity and specificity of urinary NMP22 and CK18 were 79.2%, 88.6% and 78.2%, 82.9%, respectively, for transitional cell carcinoma of the bladder before any treatment. The joint sensitivity of the two markers was 91.7%. The NMP22 and CK18 levels were significantly lower in the recovered patients after surgical operation (P < 0.01), while in patients with recurrence or metastasis the levels of the markers were significantly higher (P < 0.01). There was a significant relationship between NMP22 and CK18, (r = 0.689, P < 0.01). The levels of urinary nmp22 and CK18 were significantly different among pathological grade G1, G2, G3, and stage Ta, T1, T2, T3 (P < 0.01).

CONCLUSIONNMP22 and CK18 are useful tumor marker for diagnosis of transitional cell carcinoma of the bladder and for monitoring the state of illness. The joint use of the two markers can improve the sensitivity of cancer detection. NMP22 and CK18 may become a new class of tumor markers, and to be the basis for development of a new assay with an increased efficacy for the detection and treatment of bladder cancer.

OBJECTIVETo study the association of the changes of serum insulin, insulin-like growth factor (IGF-1), insulin-like growth factor binding proteins(IGFBPs), body mass index (BMI), waist and hip circumference ratio(WHR) with the genesis of colorectal cancer.

METHODSSera from 244 colorectal cancer patients before operation, 371 patients after operation and 150 healthy subjects were assayed for insulin, leptin, IGF-1, IGFBP-1 and IGFBP-3 by the enzyme-linked immunosorbent assay. SPSS 13.0 statistics software was applied to analyze the data.

RESULTSThe serum levels of insulin, IGF-1 and the ratio of IGF-1/ IGFBP-3 in colorectal cancer patients before and after surgical treatment were significantly higher than those in controls. The serum levels of IGFBP-3 in patients before and after operation were significantly lower than those in controls, and the differences were significant(P=0.015,P=0.001, respectively). The BMI in colorectal carcinoma patients was not significantly different to the healthy controls(P>0.05). The WHR in colorectal carcinoma patients was higher than that in healthy subjects, and the difference was significant(P=0.003, P=0.035 respectively). The WHR in colon cancer patients was different to that in rectal cancer patients(P=0.046). The WHR and BMI in colon carcinoma patients were positively correlated with the serum insulin level and the value of IGF/IGFBP3. The WHR and BMI were negatively correlated with IGFBP3. The WHR and BMI were not correlated with IGF-1 and IGFBP1.

CONCLUSIONSThe serum insulin, IGF-1 levels and the value of IGF-1/IGFBP-3 are significantly increased in colorectal cancer patients, and serum IGFBP-3 level is markedly decreased, which may be related to the genesis of colorectal cancer, but are not correlated with the progress and improvement of colorectal cancer. Central adipositas may be a risk factor for the genesis of colon cancer.
