Objective To explore the association between ACTN3 gene R577X polymorphism and serum lipid levels in an elderly Chinese Han population.Methods This study was based on the ageing arm of The Rugao Longevity and Ageing Study (RtLAS).Genotyping was performed by Taqman MGB method.Lipids includedtotal cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C).Cut points of dyslipidemia were based on that reported in the NCEP ATPIII.We explored the associations between R577X polymorphism loci and dyslipidemia by using analysis of covariance and logistic regression analysis.Results Overall 1 618 samples was included (741 males and 877 females) in this study.Covariance analysis found that TC level of RR,XX and RX genotype in the general population were 1.34,1.37,1.43 mmol/L with an increasing trend (P =0.024);TC and LDL-C levels of RR,XX and RX genotype (TC:5.13,5.29,5.43 mmol/L,P =0.004;LDL-C:2.76,2.88,3.00 mmol/L,P =0.004) were significantly different in females.Logistic regression analysis showed that the increased copies of X allele were significantly associated with increased TC and LDL-C levels in the general population and females.For the general population,TC:OR=1.184,95％CI:1.030-1.361,P =0.018;LDL-C:OR =1.334,95％CI:1.101-1.588,P=0.003;For females,TC:OR=1.332,95％ CI:1.102-1.616,P =0.003;LDL-C:OR =1.549,95 ％CI:1.208-1.986,P =0.001.After adjusting for other covariates,the above associations remained significant.Conclusions ACTN3 gcnc R577X polymorphism is associated with plasma TC and LDL-C levels in elderly woman of Han populations in Rugao,China.

Objective:To explore the optimal local treatment pattern of supraclavicular lymph node in breast cancer patients with synchronous ipsilateral supraclavicular lymph node metastasis (sISLM).Methods:Clinical data of 128 breast cancer patients with sISLM admitted to the Fourth Hospital of Hebei Medical University from 2010 to 2015 were retrospectively analyzed. Among them, 68 cases were treated with supraclavicular lymph node dissection combined with radiotherapy, and 60 cases received radiotherapy alone. The locoregional recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), progression-free survival (PFS) and overall survival (OS) were statistically compared between two groups.Results:Univariate analysis demonstrated that the 5-year LRFS, DMFS, PFS and OS did not significantly differ between two groups (all P>0.05). Multivariate analysis revealed that the local treatment pattern of supraclavicular lymph node was an independent prognostic factor for the 5-year DMFS, PFS and OS (all P<0.05). Subgroup analysis showed that when radiotherapy alone was performed, the 5-year OS of patients in the supraclavicular region radiation dose of>50 Gy group were significantly better than that in the 50 Gy group ( P=0.047). When supraclavicular lymph node dissection combined with radiotherapy was delivered, if the number of dissection was less than 10, the 5-year LRFS, DMFS, PFS, OS of patients in the>50 Gy group were all better than those in the 50 Gy group numerically without statistical significance (all P>0.05). If the number of dissection was ≥10, the 5-year LRFS, DMFS, PFS, OS in the 50 Gy group were better than those in the>50 Gy group numerically, whereas significant difference was only found in the 5-year DMFS ( P=0.028). Conclusions:Supraclavicular lymph node dissection combined with radiotherapy may be the optimal local treatment pattern for supraclavicular lymph node. When radiotherapy alone is performed, a radiation boost to the supraclavicular region may improve OS. When supraclavicular lymph node dissection combined with radiotherapy is performed, if the degree of dissection is low, a radiation boost to the supraclavicular region may bring clinical benefits. However, if the degree of dissection is high, a radiation boost to the supraclavicular region may not bring significant clinical benefits.

Objective To explore the clinical effects of transvaginal acupoint injection in the treatment of chronic pelvic pain induced by pelvic floor myofascitis. Methods All 80 patients with pelvic floor myofascitis were randomly assigned to an observation group and a control group, with 40 patients in each group. The observation group was given the treatment of transvaginal pain spot injection, and the control group was given transvaginal non-pain spot injection. Changes of clinical symptoms, signs, pain scores and other indices before the treatment, 1 week and 2 weeks after the treatment between the two groups of patients were observed and compared. Results Comparison of pain scores between the treatment group and the control group before the treatment was not significantly different (P>0.05); pain scores after the treatment in the two groups were significantly lower compared to those before the treatment, and the differences in the two groups were both significant (P<0.01). The curative effects in the treatment group were better than those in the control group (P<0.01). Conclusion Transvaginal acupoint injection is able to significantly alleviate chronic pelvic pain induced by pelvic floor myofascitis, but accurate pain spot injection is required.

Objective:To explore the possible pathogenic mechanism of the central nervous system by studying the neurodegenerative diseases caused by tick-borne encephalitis virus (TBEV) infection in mice.Methods:The mice were intracranially inoculated with TBEV, 8 days later the mice were sacrificed, the brain tissues of all mice were collected and observed after HE staining to verify if the model was successfully established; the expressions of neuronal nuclei (NeuN), glial fibrillary acidic protein (GFAP), proliferating cell nuclear antigen (PCNA) and reduced upon activation, normal T cell expressed and secreted (RANTES) in mouse brain tissue were detected by immunohistochemical method, the number of positive cells was counted and the gray value was analyzed to calculate the score.Immunofluorescence combined with laser scanning confocal microscopy were used to observe the distribution of NeuN and GFAP positive cells and the expression of RANTES and PCNA.Results:The number of NeuN-positive cells in the brain tissue of mice infected with TBEV decreased, while the GFAP-positive cells increased. Furthermore, astrocytes proliferated faster than neurons, and RANTES was mainly produced by astrocytes.Conclusions:TBEV infection could cause neurotoxic reactions in brain tissue, leading to nerve cells death and activating astrocytes which produces many RANTES.

PURPOSE: The aim of this study is to explore signal transducer and activator of transcription 3 (STAT3) expression in breast cancer and to analyze the detailed mechanism that STAT3 contributes to the progression of breast cancer. METHODS: We retrospectively analyzed the clinicopathologic characteristics and overall survival (OS) of 140 breast cancer patients after curative surgery, and detected STAT3 expression, phosphorylated STAT3 (pSTAT3) expression, Ki-67 expression, vascular endothelial growth factor (VEGF)-C and -D expression in breast cancer tissues, and adjacent nontumor tissues. Survival analysis and relationship analysis were adopted for demonstrated the important mechanism of STAT3 contribution to progression of breast cancer. RESULTS: STAT3 expression, pSTAT3 expression, Ki-67 expression, VEGF-C expression, and VEGF-D expression in breast cancer tissues were significantly higher than those in adjacent nontumor tissues, respectively. With survival analysis, only number of lymph node metastasis (N stage) was identified as the independent predictors of the OS of breast cancer patients. Besides, we demonstrated there was the most prominent correlation between STAT3 expression and lymph node metastasis in breast cancer tissues by using the multinominal regression method. CONCLUSION: STAT3, a poor survival biomarker potential association with lymph node metastasis, was suitable for predication the OS of breast cancer patients after curative resection.

Objective To evaluate the effect of enhanced recovery after surgery (ERAS) on immune function and clinical signs in patients with acute abdomen.Methods From March 2016 to March 2017,patients with acute abdominal admitted in the Emergency Care Center of the First Affiliated Hospital of Zhengzhou University were collected and randomized into ERAS group and conventional peri-operative management group (CPM group).In addition to clinical signs (the time of bowel movemtn recovery,the time of first postoperative ingestion and ambulation,hospital stay,complication rates),the celluar immunity (CD4 +,CD8 +,CD4 +/CD8 +) were determined during peri-operation period.Results A cohort of 240 patients were in ERAS group and 192 patients in CPM group.There was no significant difference in general condition between the two groups (P ＞ O.05).On the first day after operation,the levels of CD4 +,CD4 + /CD8 + decreased in both groups (P ＜ 0.05),but the CPM group had lower levels of CD4 +,CD4 +/CD8 +than the ERAS groups.On the 3rd and 7th days after surgery,the ERAS groups had higer levels of CD4+,CD4+/CD8+ than the CPM groups,(the levels of CD4+,CD4+/CD8+ recovery on the 3rd and 7th day after operation,and the ERAS group was significantly better than the CPM group) (P ＜ 0.05).Compared with CPM group,the recovery of bowel movement appeared earlier after operation in ERAS group with sooner resuming ingestion and ambulation after operation,shorter hospital stay,and lower WHO pain rating scale and complication rates (P ＜ O.05).Conclusions ERAS for patients with acute abdomen can alleviate postoperative suppression of immunity,preserving immune function intact and accelerating postoperative rehabilitation.

Objective: To evaluate the prognostic value of ¹⁸F-fluorodeoxyglucose positron emission tomography (PET)/computed tomography (CT) in patients with diffuse large B cell lymphoma (DLBCL) undergoing autologous hematopoietic stem cell transplantation (auto-HSCT). Methods: Forty-eight patients with DLBCL treated at Peking University Cancer Hospital between November 2010 and December 2014 were assessed. All patients underwent PET/CT scanning prior to or after auto-HSCT. Correlation analysis was done based upon patients characteristics, PET/CT scan results and survival. Results: ①Among 48 patients, 27 was male, 21 female, median age was 43 (17-59) years old. ② Patients with negative pre-auto-HSCT PET/CT assessment demonstrated significantly better 3-year progression free survival (PFS) (87.1% vs 53.3%, χ²=7.02, P=0.019) and overall survival (OS) (90.3% vs 60.0%, χ²=6.51,P=0.022) than patients with positive pre-auto-HSCT PET/CT assessment. Three-year PFS (94.1% vs 30.0%, χ²=22.75, P=0.001) and OS (97.1% vs 40.0%, χ²=21.09, P=0.002) were also significantly different between patients with negative and positive post-auto-HSCT PET/CT assessment. ③ Multivariate analysis indicated a significant association of PFS (HR=13.176, P=0.005) and OS (HR=20.221, P=0.007) with post-auto-HSCT PET/CT assessment. Number of prior treatment regimens was associated with PFS (HR=10.039, P=0.040). ④ Harrell’s C index revealed that the value of combined use of number of prior treatment regimens and post-auto-HSCT PET/CT assessment was superior to either one used alone in PFS (Harrell’s C values were 0.976, 0.869 and 0.927 in combined use, number of prior treatment regimens and post-auto-HSCT PET/CT assessment, respectively), and the combined use of ECOG performance status and post-auto-HSCT PET/CT assessment significantly increased the Harrell’s C index in OS (Harrell’s C values were 0.973, 0.711 and 0.919 in combined use, ECOG performance status and post-auto-HSCT PET/CT assessment, respectively). Conclusions Post-auto-HSCT PET/CT assessment is the main predictor of outcomes in DLBCL patients receiving auto-HSCT. Combined use of post-auto-HSCT PET/CT assessment and number of prior treatment regimens and ECOG performance status is a better prognostic tool in patients with DLBCL undergoing transplantation.
