Objectives: To study the changes of blood levels of soluble semaphorin 4D (sSema4D) and matrix metalloproteinases-14 (MMP-14);to explore the correlation between sSema4D and ventricular remodeling in patients of dilated cardiomyopathy with chronic heart failure.
Methods: Our research included in 2 groups:Dilated cardiomyopathy group, n=86 patients and Control group, n=32 healthy subjects. Blood levels of sSema4D, MMP14, Pro-BNP and hs-CRP were examined by ELISA. Left atrial diameter (LAD), right ventricular diameter (RVD), ejection fraction (EF), left ventricular end diastolic diameter (LVEDD), left ventricular fractional shortening (LVFS) were measured by echocardiography. Correlation analysis between blood levels of sSema4D, MMP-14 and the parameters for left ventricular remodeling was conducted.
Results: Blood levels of sSema4D and MMP14 were different between 2 groups, P<0.005. In Dilated cardiomyopathy group, sSema4D level was positively related to MMP-14 and LVEDD (r=0.462, P=0.001 and r=0.643, P<0.001) respectively.
Conclusion: Serum level of sSema4D might be related to ventricular remodeling in patients with dilated cardiomyopathy which could be used as risk factor for predicting the prognosis of heart failure in relevant patients.

Objective To observe the dynamic changes of ghrelin of spleen-qi-deficiency rats and the intervention effects ofSijunzi Decoction.Methods Experimental rats were randomly divided into normal control group, model group andSijunzi Decoction group. Except for normal control group, spleen-qi-deficiency model was copied through the two-factor methods of breaking qi by bitter cold and swimming exhausted. Meanwhile,Sijunzi Decoction group was given 20 g/(kg?d)Sijunzi Decoction intervention. The activities of GAS, MTL, SS and VIP at different time points (14, 21, 28 d) in intestine and serum were detected by ELISA and RIA. At the same time the intervention effect of Sijunzi Decoction was studied.Results Compared with normal control group, GAS and MTL in intestine and serum of model rats decreased, while SS and VIP increased (P<0.05,P<0.01). Compared with model group, GAS and MTL in intestine and serum of rats in theSijunzi Decoction group increased, while SS and VIP decreased (P<0.05,P<0.01).Conclusion Ghrelin in intestine and serum of spleen-qi-deficiency rats shows dynamic coincidental changes.Sijunzi Decoction can treat spleen qi deficiency by regulating the activities of rat ghrelin.

Objective To analyze the clinical efficacy of the laparoscopic breast-conserving surgery combined with radiofrequency ablation to treat the early-stage breast cancer.Methods We collected 55 patients diagnosed early-stage breast cancer in retrospect,which started from January 2014 to December 2016.Twenty-seven of them were performed the laparoscopic breast-conserving surgery combined with radiofrequency ablation while others went through laparoscopic breast-conserving surgery without radiofrequency ablation.Meanwhile,we adopted the student t-test and the chi-square test to compare results of two groups.More specific,the main indexes of this study are including the post-operative local recurrence,the incidence of fat liquefaction or the incision-infection,operation time,post-operative hospital stay and the hospitalization expense.Results The laparoscopic breast-conserving surgery combined with radiofrequency ablation group had low local-recurrence than the laparoscopic breastconserving surgery group (0 and 7.69％).Additionally,there were no statistical differences between two groups in the incidence of fat liquefaction.However,The laparoscopic breast-conserving surgery combined with radiofrequency ablation group had more hospitalization expense than the laparoscopic breast-conserving surgery group [(4.1 ± 0.7) ten thousand yuan and (2.3 ± 0.6) ten thousand yuan,P ＜ 0.05].Conclusions Although the laparoscopic breast-conserving surgery combined with radiofrequency ablation group remarkably increased the hospitalization expense because of the utility of the radiofrequency ablation related apparatus,it may provide the probability of shaving more residual tumor cell and may low down the recurrence,especially not rising up the incidence of the post-operative fat liquefaction.Therefore,this surgery method might be one of the potential developments in the minimal-invasive of early stage breast cancer.

Compared with model 21 d group, content of NPY was increased (P<0.05), content of VIP and relative expression of Mapk14 mRNA in small intestine tissue were decreased (P<0.05) in treatment group. Conclusion Yiqi Jianpi herb has functions of adjusting NPY, VIP secretion and inhibiting abnormal expression of Mapk14 mRNA.

Objective:To analyze how the surface marker of breast cancer stem cell related to chemotherapy resistance and postoperative recurrence.Methods:The GEO public database GSE25066 and GSE32603 were used to extract clinical data including pathological evaluation of neoadjuvant chemotherapy, postoperative follow-up recurrence and recurrence time, and the expression levels of the following 18 breast cancer stem cell marker genes were extracted: CD44, CD24, EPCAM, CD49f, PROM1, CD61, ALDH1A1, CD10, ALDH1A3, ABCG2, RANK, CD47, CD166, SLUG, SOX2, SXO9, SOX10, MYC. A total of 488 patients with GSE25066 were divided into pathology compete response(pCR) group ( n=99) and residual disease (RD) group ( n=389) according to the pathological analysis. Another 418 patients with complete recurrence data was divided into recurrence group ( n=111) and non-recurrence group ( n=307), they were used for prognosis analysis. The effects of each tumor stem cell marker on chemotherapy sensitivity and tumor recurrence were analyzed by logistic, lasso and COX regression. The gene expression level of GSE32603 before and after neoadjuvant chemotherapy were used to analyze the changes after neoadjuvant chemotherapy in 166 patients, to determine the enrichment effect of chemotherapy on stem cells. Results:In chemotherapy response analysis, tumor stem cell markers CD44( OR=0.78, 95% CI: 0.63-0.98) and SANI2 ( OR=0.80, 95% CI: 0.68-0.93) were negatively correlated with neoadjuvant chemotherapy sensitivity, and CD24( OR=1.18, 95% CI: 0.97-1.47) was positively correlated with chemosensitivity. In the recurrence correlation analysis, the patients with CD44 + ( OR=1.22, 95% CI: 0.98-1.51), CD24 low( OR=0.94, 95% CI: 0.79-1.11) and SANI2( OR=1.17, 95% CI: 1.00-1.37) expression have a high recurrence rate. As chemotherapy progressed, the MME, CD49f, SOX10, MYC, and SOX9 ( P<0.05) showed an enrichment process. Conclusions:Breast cancer stem cell markers CD44 + CD24 - and SLUG can be used to predict the efficacy of neoadjuvant chemotherapy and recurrence after tumor treatment. They are relatively stable marker for studying breast cancer stem cells.

Objective:To compare the efficacy of radial forearm flap and anterolateral thigh flap in repairing soft tissue defects after oral cancer surgery and to explore their indications.Methods:A retrospective analysis was conducted on clinical data of patients with oral cancer treated at the Department of Stomatology, Affiliated Hospital of Nantong University, from May 2019 to February 2023. Patients were divided into two groups based on the repair method: the radial forearm flap group and the anterolateral thigh flap group. The groups were compared in the following aspects. (1) Surgical parameters including defect area after oral cancer resection, flap area, flap preparation time, operation time, and length of hospital stay. (2) Inflammatory markers (interleukin-6 and C-reactive protein levels) measured 1 day before surgery and 1 day after surgery. (3) Flap survival rate was calculated. (4) Complication rates was calculated in the flap donor area and infection rates in the oral recipient area within 6 months postoperatively. (5) Six months postoperatively, the patient’s oral function was assessed by a physician using the University of Washington quality of life scale (UW-QOL). The evaluation included assessments of oral opening, speech, and eating functions. Each parameter was scored on a scale of 0 to 10 (higher scores indicated better recovery). (6) Quality of life was assessed using the 36-item short form health survey scale(SF-36) at 2, 4 and 6 months postoperatively, with scores ranging from 0 to 100 (higher scores indicated better quality of life). (7) Patient satisfaction was assessed at 6 months postoperatively, with satisfaction levels categorized as satisfied, basically satisfied, and dissatisfied. The satisfaction rate was calculated as (satisfied + basically satisfied ) cases / total cases in each group × 100%. Statistical analysis was performed using SPSS 22.0. Measurement data were expressed as Mean±SD, and comparisons between groups were conducted using t-tests. Count data were expressed as cases and (or) percentages, and comparisons were made using chi-square test. P<0.05 was considered statistically significant. Results:The radial forearm flap group included 48 cases (32 males, 16 females), aged (49.3±5.0) years, with a body mass index (BMI) of (23.0±1.1) kg/m 2 and a disease course of (6.5±2.1) months. The group had 21 cases of tongue cancer, 12 of floor of mouth cancer, and 15 of buccal cancer, including 40 squamous cell carcinomas and 8 basal cell carcinomas. The anterolateral thigh flap group included 32 cases (20 males, 12 females), aged (50.1±5.0) years, with a BMI of (23.0±1.0) kg/m 2 and a disease course of (7.0±2.2) months. The group had 16 cases of tongue cancer, 7 cases of floor of mouth cancer, and 9 cases of buccal cancer, including 27 squamous cell carcinomas and 5 basal cell carcinomas. There were no significant differences in gender, age, BMI, disease course, tumor location, or pathological type between the two groups ( P>0.05). The defect area after oral cancer resection was smaller in the radial forearm flap group[ (39.0±1.3) cm 2 ] compared to the anterolateral thigh flap group[ (40.3±2.2) cm 2] ( t=3.32, P=0.001). There were no significant differences in flap area, flap preparation time, or length of hospital stay between the two groups ( P>0.05). The operation time was shorter in the radial forearm flap group [(5.1±1.1) h] compared to the anterolateral thigh flap group [(6.8±2.8) h] ( t=0.26, P<0.001). There were no significant differences in interleukin-6 and C-reactive protein levels between the two groups 1 day before surgery and 1 day after surgery ( P>0.05). The flap survival rates were 97.9% (47/48) in the radial forearm flap group and 93.8% (30/32) in the anterolateral thigh flap group, with no significant difference( P>0.05). Postoperative donor site complications mainly included infection, pigmentation, itching, etc. The overall incidence of complications in the donor site of the radial forearm flap [33.3% (16/48)] was higher than that in the anterolateral thigh flap group [12.5% (4/32)], and the difference was statistically significant ( χ2=4.44, P=0.035). There was no significant difference in infection rates in the oral recipient area between the two groups ( P>0.05). Six months postoperatively, the average scores for oral opening, speech, and eating functions were above 7 in both groups, with no significant differences ( P>0.05). Quality of life scores improved over time in both groups, with average scores above 90 at 6 months postoperatively, and no significant differences at any time point ( P>0.05). The patient satisfaction rate was 91.7% (44/48) in the radial forearm flap group and 90.6% (29/32) in the anterolateral thigh flap group, with no significant difference ( P>0.05). Conclusion:Both radial forearm flap and anterolateral thigh flap can effectively repair soft tissue defects after oral cancer resection, significantly improving patients’oral function. The anterolateral thigh flap provides sufficient tissue volume and is suitable for patients with larger defect areas. The radial forearm flap is suitable for patients with a smaller defect area after oral cancer resection. Its surgical procedure is relatively less complex and offers an advantage in reducing surgery time. However, the donor site complications are higher with the radial forearm flap compared to the anterolateral thigh flap.
