Objective:To compare the dosimetric differences between volumetric-modulated arc therapy (VMAT) and intensity-modulated radiation therapy (IMRT) on planning target volume (PTV) and organ-at-risk (OAR) for breast cancer after modified radical mastectomy, aiming to provide evidence-based reference for clinical practice.Methods:According to strict inclusion and exclusion criteria, literature search was performed in PubMed, Cochrane Library, FMRS, CNKI, Wanfang Data and VIP full text databases from the inception of databases up to March 2020. The controlled clinical trials of dosimetric comparison between VMAT and IMRT for breast cancer following modified radical mastectomy were selected. The meta-analysis was performed using Stata14 software.Results:The meta-analysis included 281 patients from 13 observational studies. Compared with IMRT, VMAT significantly increased the PTV dose coverage D 95%( P<0.001) and significantly improved the PTV homogeneity index (HI, P<0.001) and conformity index (CI, P=0.004). Compared with IMRT, VMAT more effectively decreased the ipsilateral lung V 20Gy (WMD=1.332, P=0.027) and contralateral lung V 10Gy ( P=0.003). There were no significant differences in theD mean, V 5Gy, V 10Gy and V 30Gy of the ipsilateral lung, D mean and V 5Gy of the contralateral lung, D mean, V 10Gy and V 30Gy of the heart between VMAT and IMRT (all P>0.05). Compared with VMAT, IMRT reduced the cardiac V 5Gy ( P=0.001). However, sensitivity analysis of included literature on cardiac V 5Gy showed that the P value was reversed, indicating that the stability of the results was poor. VMAT significantly shortened the delivery time ( P<0.001) and the number of monitor units ( P<0.001) compared to IMRT. Conclusion:Compared with IMRT, VMAT can achieves superior target dose coverage, HI and CI, better protection for the ipsilateral and contralateral lung, fewer monitor units and shorter delivery time.

OBJECTIVE:
To evaluate the association between single nucleotide polymorphisms of calcium/calmodulin-dependent kinase 4 (CAMK4) and the therapeutic effect of amlodipine in essential hypertensive patients in Chinese Han nationality.
METHODS:
A total of 108 mild-to-moderate essential hypertension patients in Chinese Han nationality were treated with amlodipine for 8 weeks at a dosage of 5 mg/d. Polymerase chain reaction-restriction fragment length polymorphism was performed to detect the genotypes (rs10491334). Blood pressure was measured and analyzed.
RESULTS:
The result of rs10491334 polymorphism of CAMK4 was consistent with Hardy-Weinberg equilibrium distribution and the frequencies of C allele and T allele were 88.89% and 11.11%, respectively. The systolic blood pressure and diastolic blood pressure before amlodipine treatment were not statistically different among different genotype carriers (P>0.05). The blood pressure was significantly reduced in all patients after amlodipine treatment (P<0.05). Systolic blood pressure was significantly decreased in patients with rs10491334 CC genotype and CT genotype compared with those patients with rs10491334 TT genotype. Total effective rates of CT and TT carriers were higher than those of the CC genotype carriers (P<0.01).
CONCLUSION
The CAMK4 gene polymorphism might be associated with the efficacy of calcium channel blocker in treating mild-to-moderate essential hypertension patients.

OBJECTIVE:
To investigate the effect Pinggan Qianyang recipe on expression of Tpx, HSP27 and ANXA1 in the hypothalamus of spontaneously hypertensive rats (SHRs) with the hyperactivity of liver-YANG syndrome.
METHODS:
A total of 30 SHRs were subjected to administration of Aconiti Praeparatae Decoction to establish the model of SHR with liver-YANG hyperactivity first, then they were randomly divided into three groups: the control group, the model group and the treatment group (n=10 per group). A total of 10 SD rats were served as the normal group. The rats in control group and treatment group were given Enalapril plus Pinggan Qianyang recipe for four weeks. The change of behavior and blood pressure of rats were monitored. RT-PCR and Western-blot were performed to detect the expression of Tpx II, HSP27 and ANXA1 mRNA and protein in the hypothalamus, respectively.
RESULTS:
Compared with the normal SD rats, the heart rate, blood pressure and grade of irritability were significantly increased while rotation endurance time was dramatically reduced in the SHR model with liver-YANG hyperactivity (P<0.01), these changes were reversed by the application of Enalapril plus Pinggan Qianyang recipe. Compared with the normal SD rats, the protein and mRNA expression of Tpx II and ANXA1 in the model group were significantly upregulated (P<0.01) while the HSP27 was significantly downregulated (P<0.01). Compared with the model group, the protein and mRNA expression of Tpx II and ANXA1 in the control group or treatment group were significantly decreased (P<0.05 or P<0.01) while HSP27 was significantly increased (P<0.05 or P<0.01). Compared with the control group, the expression of Tpx II and ANXA1 protein in treatment group were significantly reduced (P<0.05 or P<0.01).
CONCLUSION
Pinggan Qianyang recipe can improve the blood pressure and behavior in SHRs with hyperactivity of Liver-YANG syndrome, which might be related to the regulation of Tpx, HSP27 and ANXA1 expression in hypothalamuses.

Objective: To investigate the effects of a Chinese herbal formula for calming liver and suppressing yang on the protein expressions of vascular tissues in spontaneously hypertensive rats (SHRs), and to explore the mechanism of efficacy. Methods: Twenty SHRs were randomly divided into model group and treatment group. Another 10 Wistar-Kyoto rats were selected as a normal control. SHRs in the treatment group were administered with the formula for calming liver and suppressing Yang for 4 weeks. During the course of treatment, blood pressure and heart rates were monitored every week and the ethology of rats, including irritability and rotation endurance was also evaluated. After treatment, thoracic aorta was obtained and its proteins were separated by 2-dimensional gel electrophoresis (2-DE). The differentially expressed proteins were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and database query. Results: The formula for calming liver and suppressing yang not only decreased the systolic blood pressure and heart rate, but also improved irritability degree and rotation endurance time of SHRs. This experiment had established the 2-DE graph of protein expressions of vascular tissues in SHRs. Compared with the normal group, the expressions of 15 proteins were down-regulated, and 12 proteins were up-regulated in vascular tissues of the model group. The formula for calming liver and suppressing yang treatment up-regulated expressions of 10 proteins in the 15 down-regulated proteins, and down-regulated 8 proteins in the 12 up-regulated proteins in vascular tissues of SHRs. After analysis, 16 obviously differentially expressed proteins were found, and 13 of them were identified. Conclusion: The formula for calming liver and suppressing yang can improve the ethology of SHRs. The mechanism is probably concerned with regulating the protein expressions of vascular tissues.

OBJECTIVETo observe the herbal effects on hyperthyroidism patients with syndrome of hyperactivity of liver-Yang by method for calming the liver and suppressing Yang and investigate its effects on the lymphocyte protein expression. This approach may lay a foundation for the further investigation of the curative mechanisms of calming the liver and suppressing Yang treatment.
METHODA total of 48 hyperthyroidism patients with syndrome of hyperactivity of liver-Yang were randomly divided into treatment group and control group. The treatment group was treated by method for calming the liver and suppressing Yang in accordance with traditional Chinese medicine (TCM) and the control group with thiamazole tablets for three periods of treatment The therapeutic effects, the score of TCM symptom, electrocardiogram (P wave), thyroid hormones and ultrasound were observed in both groups before and after the treatment. The side effects in the treatment course were observed in both groups. The level of differential protein expression was analyzed by two-dimensional electrphoresis and matrix assisted laser desorption/ionizaton time-of-flight mass spectrometry.
RESULTThe treatment group has the effect on stepping down the heart rate, cutting down the P wave amplitude changes, regulating the level of thyroid hormones and decreasing the volume of thyromegaly. There are not statistically significant between the treatment group and control group. However, the treatment group has obviously better effect on regulating TCM symptom and decreasing the side reaction than the control group (P<0.05). There are not statistically significant on the total effective between the treatment group and control group. The average spots in lymphocyte for normal people, before and after treating hyperthyroidism patients with syndrome of hyperactivity of liver-Yang were (429 +/- 31), (452 +/- 28) and (437 +/- 36) spots respectively. Eight down-regulated protein expressions and 11 up-regulated protein expressions were obtained in the hyperthyroidism patients with syndrome of hyperactivity of liver-Yang and normal people. Five strengthened expressions of protein were also obtained in 8 down-regulated expressions of protein and 8 lower expressions of protein in 11 up-regulated expressions of protein before and after treating the migraine patients with syndrome of hyperactivity of liver-Yang. Ten of the total 8 differential protein spots were successfully identified by MALDI-TOF-MS. The functions of these proteins were involved in metabolism associated, transportation, antioxidation, sigal transduction and immume associated protein, etc. according to information provided by NCBI and MSDB database.
CONCLUSIONIn this study, the TCM complex prescription with herbs for calming the liver and suppressing Yang can regulate the thyroid hormones, improves TCM symptoms, and decrease the adverse reaction. It can possibly regulate lymphocyte protein expression.

OBJECTIVETo observe the therapeutic effect of calming the liver and restraining the Yang formula in treating patients with mild or moderate degree of essential hypertension (syndrome of hyperactivity of liver-Yang), and to explore its mechanism in lowering blood pressure.
METHODThe 348 patients with EH of stage I , II were randomly divided into two groups, the 174 patients in the treated group were treated with the calming the liver and restraining the Yang formula, and the 174 patients in the control group were treated with amlodipine. The treatment course for them all was 12 weeks. The related clincial symptoms score and quality of life score estimated before and after treatment at 4th week, 8th week and 12th week were observed. Before and after treatment, the ambulatory blood pressure (AMBP), heart rate, blood lipid, serum livels of high-sensitivity C-reactive protein (Hs-CRP), Angiotensin-II (Ang II) and calcitonin gene-related peptide (CGRP) were measured respectively in 40 patients of the treared group and 40 patients of the control group.
RESULTAfter treatment, the treatment in the treated group showed an effect better than that in the control group in terms of nigh-time blood pressure reducing rate (P < 0.05). The reducing blood pressure variability and total effective rate in the treated group were no significant than that in the control group. In respect of reducing symptomatic scores on dizzy, soreness and weakness of the waist and knees, disturbed and dry and bitter of mouth, ameliorating quality of life score, decreasing the levels of heart rate, total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol(HDL-C) in the treated group were showing marked improvement as compared with that in the control group (P < 0.05 or P < 0.1). The improvement in the level of Ang II , Hs-CRP and CGRP before treatment in two groups were more significant than that after treatment (P < 0.05). However There were no difference in after treatment between the treated group and the control group.
CONCLUSIONThe calming the liver and restraining the Yang formula shows favorable efficacy in lowering blood pressure on the patients with mild or moderate degree of essential hypertension. It can reduce the clincial symptoms, improve the quality of life, regulate blood lipid metabolism. Its mechanism may be related to the functional relieving inflammatory reaction and inhibition the activity of renin-angiotensin-aldosterone system (RAAS).
