Objective:
To analyze the differentially expressed genes related to the chemosensitivity with the TPF regimen for hypopharyngeal squamous cell carcinoma and to measure potential functional targeting genes expressions.
Methods:
Twenty-nine patients with primary hypopharyngeal cancer who underwent induction chemotherapy with TPF from January 2013 to December 2017 in Beijing Tongren Hospital were enrolled for microarray analysis, including 28 males and 1 female, aged from 43 to 73 years old. Among them, 16 patients were sensitive to chemotherapy while 13 patients were non-sensitive. Illumina Human HT-12 Bead Chip was applied to analyze the gene expressions and online bioinformatics analysis was used to analyze the differentially expressed genes. Reverse transcription and quantitative real-time PCR (RT-qPCR) was used to measure the mRNA expression of potential functional genes of TPF induction chemotherapy in 43 samples, 29 from original patients and 14 from additional patients. Graphpad prism 7.0 software was used for statistical analysis.
Results:
A total of 1 381 significantly differentially expressed genes were screened out. By GO analysis, up-regulated genes included sequestering in extracellular matrix, chemokine receptor binding and potassium channel regulator activity; down-regulated genes included regulation of angiogenesis, calcium ion binding and natural killer cell activation involved in immune response. With KEGG database analysis, down-regulated pathways included ECM-receptor interaction and peroxisome and up-regulated pathways included Glutathione metabolism and PPAR signaling pathway. The expressions of CD44 and IL-6R were significantly different and appeared biologically significant. CD44 was significantly upregulated in insensitive tissues (0.54±0.06) compared with sensitive tissues (0.33±0.04)(

OBJECTIVE:
Identification of new risk factors is needed to improve prediction of adverse outcomes in patients with three-vessel disease (TVD). The present study aimed to evaluate the prognostic values of serum chloride and sodium levels in patients with TVD.
METHODS:
We used data from a prospective cohort of consecutive patients with angiographically confirmed TVD. The primary endpoint was all-cause death. Cox proportional hazard regression was used to analyze the relationship of serum chloride and sodium levels with long-term outcomes of TVD patients.
RESULTS:
A total of 8,318 participants with available serum chloride and sodium data were included in this analysis. At baseline, patients in the low tertiles group of serum chloride level (⪕ 102.0 mmol/L) or serum sodium level (⪕ 139.0 mmol/L) had more severe disease conditions. During a median follow-up of 7.5-year, both low serum chloride level and low serum sodium level were found to be associated with an increased risk for mortality in univariate analysis. However, when both parameters were incorporated into a multivariate model, only low serum sodium level remained to be an independent predictor of all-cause death (hazard ratio: 1.16, 95% confidence interval: 1.01-1.34, P = 0.041). Modest but significant improvement of discrimination was observed after incorporating serum sodium level into the Synergy between percutaneous coronary intervention (PCI) with Taxus and Cardiac Surgery score.
CONCLUSION
Serum sodium level is more strongly associated with long-term outcomes of TVD patients compared with serum chloride level. Low serum sodium level is an independent risk factor for mortality, but only provides modest prognostic information beyond an established risk model.

Angiotensin (Ang)-(1-7) is an important biologically-active peptide of the renin-angiotensin system. This study was designed to determine whether inhibition of Ang-(1-7) in the hypothalamic paraventricular nucleus (PVN) attenuates sympathetic activity and elevates blood pressure by modulating pro-inflammatory cytokines (PICs) and oxidative stress in the PVN in salt-induced hypertension. Rats were fed either a high-salt (8% NaCl) or a normal salt diet (0.3% NaCl) for 10 weeks, followed by bilateral microinjections of the Ang-(1-7) antagonist A-779 or vehicle into the PVN. We found that the mean arterial pressure (MAP), renal sympathetic nerve activity (RSNA), and plasma norepinephrine (NE) were significantly increased in salt-induced hypertensive rats. The high-salt diet also resulted in higher levels of the PICs interleukin-6, interleukin-1beta, tumor necrosis factor alpha, and monocyte chemotactic protein-1, as well as higher gp91 expression and superoxide production in the PVN. Microinjection of A-779 (3 nmol/50 nL) into the bilateral PVN of hypertensive rats not only attenuated MAP, RSNA, and NE, but also decreased the PICs and oxidative stress in the PVN. These results suggest that the increased MAP and sympathetic activity in salt-induced hypertension can be suppressed by blockade of endogenous Ang-(1-7) in the PVN, through modulation of PICs and oxidative stress.

OBJECTIVE:
To investigate the effect of P53 expression on prognosis of patients with double expressor lymphoma(DEL) and the interaction between the expression of MYC, BCL2 and P53 in diffuse large B-cell lymphoma(DLBCL).
METHODS:
Eighty-eight patients with newly diagnosed DLBCL from 1st September 2012 to 31th May 2018 in Shanxi Dayi Hospital affiliated to Shanxi Medical University were selected. The expressions of MYC、BCL2、P53、CD10、BCL6、MUM and Ki-67 were tested by immunohistochemistry method. The overall survival of patients was analyzed by the Kaplan-Meier method and compared by the log-rank test. The prognostic effect of MYC, BCL2 and P53 expression was analyzed by univariate and multivariate analysis.
RESULTS:
Compared with patients without P53 expression, the patients with P53 expression had higher LDH level, higher NCCN-IPI scores, lower response to chemotherapy,poorer overall survival(OS) and a higher rate of death(P<0.05). In patients who had diffuse large B-cell lymphoma associated with MYC, BCL2 expression or MYC/BCL2 double expression, compared with the patients whom without P53 expression, P53 expression associated with a significant worse OS (P<0.05). The patients with concurrent MYC and P53 expression had a worse OS, compared with patients with either P53 or MYC expression(P<0.05). In patients with MYC/P53 co-expression, BCL2 expression did not correlate with poorer survival significantly(P>0.05). Among lymphoma patients with MYC/P53, MYC/BCL2 and BCL2/P53 co-expression, the patients with MYC/P53 co-expression had the worse OS (3 year OS rate:31.6%), followed by the subgroup of patients with MYC/BCL2/P53(3 year OS rate:46.2%), patients with MYC/BCL2/P53 expression(3 year OS rate: 636%) showed a longer OS compared with the other two subgroups(P<0.05). Multivariate analysis demonstrated that P53 expression and NCCN-IPI were independent prognostic factors in this patient cohort.
CONCLUSION
P53 and MYC expressions have a synergistically negative prognostic effect in DLBCL patients. P53 expression augments the negative prognostic effect of MYC/BCL2 double expression. Patients with MYC/P53 co-expression have a worse prognosis in comparison with the patients with MYC/BCL2 double expression.

OBJECTIVE:
To observe the effects of herbal-cake-separated moxibustion on the repair of damaged vascular endothelium structure and the content of stromal cells derived factor 1 (SDF-1) in rabbits with atherosclerosis.
METHODS:
A total of 75 rabbits were randomly divided into a normal group, a model group, a direct moxibustion group, an atorvastatin calcium group and a herbal-cake-separated moxibustion group, 15 rabbits in each one. The rabbits in the normal group were fed with normal diet, and the remaining rabbits were fed with high-cholesterol diet for 12 weeks to prepare atherosclerotic model. Two groups of acupoints, one was "Juque" (CV 14), "Tianshu" (ST 25) and "Fenglong" (ST 40), the other one was "Xinshu" (BL 15), "Ganshu" (BL 18) and "Pishu" (BL 20), were applied in the direct moxibustion group and herbal-cake-separated moxibustion group; the two groups of acupoints were selected alternatively every other day. The moxibustion was given for 30 min per treatment, once a day for 4 weeks. The rabbits in the atorvastatin calcium group were treated with atorvastatin calcium tablets (1.96 mg•kg•d) which were crushed into powder and mixed into breakfast. After modeling, the rabbits in the normal group and model group received no treatment, and immobilized at the time when moxibustion was applied in other three groups. The levels of total cholesterol (TC) and triglyceride (TG) were measured by enzymic method; the low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were measured by colorimetric method; the morphological structure of aortic wall was observed under optical microscope; the serum level of SDF-1 was determined by enzyme-linked immunosorbent assay (ELISA).
RESULTS:
After treatment, compared with the normal group, the levels of TC, TG and LDL-C were significantly increased in the model group (all <0.01), and the level of HDL-C was decreased (<0.01). Compared with the model group, the levels of TC, TG and LDL-C were significantly decreased (all <0.01), and the level of HDL-C was significantly increased in the direct moxibustion group, atorvastatin calcium group and herbal-cake-separated moxibustion group (<0.01, <0.05). Compared with the normal group, the morphological structure of aortic wall was significantly damaged in the model group. Compared with the model group, the vascular endothelial structure was improved in the atorvastatin calcium group and herbal-cake-separated moxibustion group, and the pathological change of aorta endothelial in the direct moxibustion group was relieved. After treatment, compared with the model group, the level of SDF-1 was increased in the direct moxibustion group, atorvastatin calcium group and herbal-cake-separated moxibustion group (<0.05, <0.01); the level of SDF-1 in the herbal-cake- separated moxibustion group was higher than that in the direct moxibustion group (<0.05).
CONCLUSION
The herbal- cake-separated moxibustion can promote the expression of SDF-1 in serum and repair the damaged aortic endothelial structure.

Objective:
To investigate the effect of iron shield at different depths within main protection wall on the dose rate outside the protection wall.
Methods:
By adopting the FLUKA code, a therapeutic room model was constructed with its primary protective barrier consisting of concrete and iron. In order to obtain its ambient dose equivalent rate distribution, the 250 MeV protons and 220 MeV protons impinging on water phantom were simulated separately.
Results:
With varying depth of iron plate embedded in barrier, the ambient dose equivalent rates in the two simulated conditions differed sinificantly at 30 cm outside the protection wall. The maximum ambient dose equivalent rate(220 MeV: 3.42 μSv/h, 250 MeV: 6.39 μSv/h) was more than 2 times higher than the minimum ambient dose equivalent rate(220 MeV: 1.75 μSv/h, 250 MeV: 3.32 μSv/h).
Conclusions
In the design of therapeutic proton accelerator, it is essential to evaluate carefully the location where the iron shield is in main protection wall.

Objective To investigate and study the relationship between abnormal monitoring and prognosis of long range video electroencephalogram(VEEG)in patients with intractable epilepsy. Methods 100 patients from March 2012 to May 2017 in our hospital whose diagnosis and treatment of refractory epilepsy were the research object,all patients were given VEEG monitoring records,epilepsy typing characteristics and antiepileptic drug(AEDs)use survey,prognosis of all patients and the correlation analysis. In 100 cases,GTCS 60 cases,CPS 30 cases,CPS-GTCS 10 cases;56 cases treated with sodium valproate,lamotrigine treatment in 44 cases. Results VEEG monitored 80 cases of epileptiform discharge in 100 patients and 20 cases without epileptiform discharge. There was no significant difference in the incidence of epileptiform discharges between different epileptic patients in VEEG monitoring(P > 0.05),and there was no significant difference in the incidence of epileptiform discharges between VEEG patients in different medication groups(P > 0.05). The total effective rate of treatment in the VEEG epileptiform discharge group was 91.3%,which was significantly lower than that of the VEEG non epileptic discharge group (100%,P < 0.05). The main adverse reactions during treatment were drowsiness , abnormal behavior, abnormal sensation and gastrointestinal reaction. There was no significant difference in monitoring epileptiform discharges between VEEG patients (P > 0.05). All adverse reactions were improved after symptomatic treatment. Conclusion The VEEG plays an important role in guiding the patients with refractory epilepsy for epilepsy typing characteristics and AEDs treatment ,so it has significant correlation to the prognosis , and it also has an important significance in assessing the prognosis.
