BACKGROUNDSeasonal influenza epidemic occurs every year in Guangzhou, which can affect all age groups. Young children are the most susceptible targets. Parents can decide whether to vaccinate their children or not based on their own consideration in China. The aim of this study was to identify factors that are important for parental decisions on vaccinating their children against seasonal influenza based on a modified health belief model (HBM).

METHODSA cross-sectional study was conducted in Guangzhou, China. A total of 335 parents who had at least on child aged between 6 months and 3 years were recruited from women and children's hospital in Guangzhou, China. Each eligible subject was invited for a face-to-face interview based on a standardized questionnaire.

RESULTSUptake of seasonal influenza within the preceding 12 months among the target children who aged between 6 months and 36 months was 47.7%. Around 62.4% parents indicated as being "likely/very likely" to take their children for seasonal influenza vaccination in the next 12 months. The hierarchical logistic regression model showed that children's age (odds ratio [OR] =2.59, 95% confidence interval [CI]: 1.44-4.68), social norm (OR = 2.08, 95% CI: 1.06-4.06) and perceived control (OR = 2.96, 95% CI: 1.60-5.50) were significantly and positively associated with children's vaccination uptake within the preceding 12 months; children with a history of taking seasonal influenza vaccine (OR = 2.50, 95% CI: 1.31-4.76), perceived children's health status (OR = 3.36, 95% CI: 1.68-6.74), worry/anxious about their children influenza infection (OR = 2.31, 95% CI: 1.19-4.48) and perceived control (OR = 3.21, 95% CI: 1.65-6.22) were positively association with parental intention to vaccinate their children in the future 12 months. However, anticipated more regret about taking children for the vaccination was associated with less likely to vaccinate children within the preceding 12 months (OR = 0.21, 95% CI: 0.08-0.52).

CONCLUSIONSThe modified HBM provided a good theoretical basic for understanding factors associated with parents' decisions on their children's vaccination against seasonal influenza.

From the three perspectives, skin stress response, medication-acupoint effect and neuroendocrine-immune system, this article discussed the action mechanism of vesiculation moxibustion therapy, to provide scientific evidence for the development of this therapy and to enhance its therapeutic efficacy.

Objective To observe the influence of either alone or combined mixed-tocopherols combined with eicosapentaenoic acid (EPA) and α-Tocopherol use on oxidized LDL (oxLDL) induced 8-hydroxy-2'-deoxyguanosine (8-OHDG) and interleukin-6 (IL-6) secretion by human umbilical vein endothelial cells(HUVECs) and to explore the potential mechanism. Method Cultured HUVECs in vitro were incubated with oxLDL, oxLDL + α-tocopherol, oxLDL + mixed-tocopherols, oxLDL + EPA, oxLDL + α-tocopherol + EPA, oxLDL + mixed-tocopherols + EPA for 24 hours, respectively. Secretion of 8-OHDG and IL-6 were detected by cell enzyme linked immunosorbent assay (ELISA). The expressions of superoxide dismutase (SOD), protein kinase C-δ (PKC-δ), phosphorylated PKC-δ (p-PKC-δ) were analyzed by Western blot. Results 8-OHDG and IL-6 secretion of HUVECs was significantly increased significantly after incubated with oxLDL for 24 hours which could be significantly attenuated in the presence of tocopherols and EPA ( alone or in combination, all P ＜ 0. 05 ) while the strongest inhibition effects were seen with combined use of mixed-tocopherols and EPA. Moreover, combination of mixed-tocopherols and EPA could also significantly increase SOD activity and decrease PKC activity (all P ＜ 0. 05 ). However, the protein expression of SOD and PKC-was similar among groups. Conclusion Combined mixed-tocopherols + EPA use enhanced the inhibiting effects on the secretion of 8-OHDG and IL-6 in oxLDL stimulated HUVECs which might be linked with increased SOD activity and reduced p-PKC activity.

OBJECTIVE: To investigate whether the level of homocysteine in patients with postpartum depression is associated with depression index. METHODS: A total of 43 women with postpartum depression or with potential postpartum depression, who visited the psychological clinic of Maternal and Child Health Hospital of Hunan Province from June, 2012 to April, 2014, were enrolled in this study. They were evaluated by the Edinburgh Postnatal Depression Scale and Hamilton Depression Scale. Chinese Classification of Mental Disorder (the third edition) was used for their diagnosis. The depressive index was calculated by Edinburgh Postnatal Depression Scale, Hamilton Depression Scale, and clinical symptom scores, which was used to assess the level of depressive symptoms. The level of homocysteine in serum was detected by chemoluminescent method. Meanwhile, another 31 women, who visited the hospital without postpartum depression, were used as controls to compare with the 43 patients. RESULTS: The homocysteine level in the women with postpartum depression was significantly higher than that in the control group [(10.09 ± 3.59) μmol/L vs (8.57 ± 1.59) μmol/L, t=12.392, P=0.001]. The depression index was positively correlated with the level of homocysteine (r=0.231, P<0.05). CONCLUSION The level of serum homocysteine is associated with postpartum depression, suggesting that the level of serum homocysteine might be a risk biomarker for postpartum depression.

BACKGROUNDGlutamic acid decarboxylase antibody (GADA) and protein tyrosine phosphatase antibody (IA-2A) are two major autoantibodies, which exert important roles in the process of type 1 diabetes mellitus (T1D). Our study aimed to investigate the changes in positivity and titers of GADA and IA-2A during the course of Chinese acute-onset T1D patients and their relationships with clinical features.

METHODSTwo hundreds and forty-seven Chinese newly diagnosed acute-onset T1D patients were consecutively recruited. GADA and IA-2A were detected at the time of diagnosis, one year later, 3-5 years later after diagnosis during the follow-up; all the clinical data were recorded and analyzed as well.

RESULTSDuring the course of acute-onset T1D, the majority of patients remained stable for GADA or IA-2A, however, a few patients changed from positivity to negativity and fewer patients converted from negativity to positivity. The prevalence of GADA was 56.3% at diagnosis, decreasing to 50.5% one year later, and 43.3% 3-5 years later while the corresponding prevalence of IA-2A were 32.8%, 31.0% and 23.3%, respectively. The median GADA titers were 0.0825 at diagnosis, declining to 0.0585 one year later and 0.0383 3-5 years later (P < 0.001), while the corresponding median titers were 0.0016, 0.0010, 0.0014 for IA-2A, respectively. Fasting C-peptide (FCP) and postprandial C-peptide 2 hours (PCP2h) levels of GADA or IA-2A negativity persistence patients were higher than those of positivity persistence and negativity conversion patients (P < 0.05) which indicated GADA or IA-2A negativity persistence T1D patients had a less loss of β cell function.

CONCLUSIONOur data suggest that repeated detection of GADA and IA-2A are necessary for differential diagnosis of autoimmune diabetes and the indirect prediction of the β cell function in Chinese patients.

Autophagy is a highly conservative and multi-component activated energy metabolism and self-renewal mechanism, which plays a crucial regulatory role in maintaining the normal physiological state of cells and is involved in various pathological processes. In recent years, the mechanism study has made great progress in regulating autophagy with effective components of Chinese materia medica(CMM),which are reported to prevent and treat cancers, neurodegenerative diseases, cardiovascular diseases and metabolic and immune-related diseases. This review outlines the molecular regulation mechanisms of cell autophagy with CMM components in controlling the above-mentioned diseases. There are many relevant reports on the regulatory mechanisms of autophagy in tumor and cardiovascular cells with CMM monomers. The main chemical structural types are alkaloids, saponins, polyphenols, flavonoids and terpenes. And m-TOR pathway is the main mechanism relating to the regulatory mechanisms of autophagy with CMM. Therefore, the regulatory mec-hanisms of cell autophagy become a new research targeting strategy of therapies with CMM. This review provides evidences for the effectiveness and scientificity of CMM in regulating autophagy, in the expectation of providing references for the in-depth studies of CMM in the field of autophagy and the development of natural autophagy regulators.

This study aims to explore the chemical composition of Rehmanniae Radix braised with mild fire and compare the effect of processing method on the chemical composition of Rehmanniae Radix. To be specific, ultra-high performance liquid chromatography with linear ion trap-orbitrap mass spectrometry(UHPLC-LTQ-Orbitrap MS) was used to screen the chemical constituents of Rehmanniae Radix. The chemical constituents were identified based on the relative molecular weight and fragment ions, literature information, and Human Metabolome Database(HMDB). The ion peak area ratio of each component before and after processing was used as the index for the variation. SIMCA was employed to establish principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) models of different processed products. According to the PCA plot, OPLS-DA plot, and VIP value, the differential components before and after the processing were screened out. The changes of the content of differential components with the processing method were analyzed. A total of 66 chemical components were identified: 57 of raw Rehmanniae Radix, 55 of steamed Rehmanniae Radix, 55 of wine-stewed Rehmanniae Radix, 51 of repeatedly steamed and sundried Rehmanniae Radix Praeparata, 62 of traditional bran-braised Rehmanniae Radix, and 63 of electric pot-braised Rehmanniae Radix. Among them, the 9 flavonoids of braised Rehmanniae Radix were from Citri Reticulatae Pericarpium. PCA suggested significant differences in the chemical composition of Rehmanniae Radix Praeparata prepared with different processing methods. OPLS-DA screened out 32 chemical components with VIP value >1 as the main differential components. Among the differential components, 9 were unique to braised Rehmanniae Radix(traditional bran-braised, electric pot-braised) and the degradation rate of the rest in braised(traditional bran-braised, electric pot-braised) or repeatedly steamed and sundried Rehmanniae Radix was higher than that in the steamed or wine-stewed products. The results indicated the chemical species and component content of Rehmanniae Radix changed significantly after the processing. The 32 components, such as rehmapicrogenin, martynoside, jionoside D, aeginetic acid, hesperidin, and naringin, were the most important compounds to distinguish different processed products of Rehmanniae Radix. The flavonoids introduced by Citri Reticulatae Pericarpium as excipient may be the important material basis for the effectiveness of braised Rehmanniae Radix compared with other processed products.

Dysmenorrhea is a common gynecological disease in clinic， with primary dysmenorrhea and secondary dysmenorrhea. Primary dysmenorrhea is usually not accompanied by organic lesions in genital organs， which is mainly related to the increase of prostaglandin content in endometrium during menstruation. Secondary dysmenorrhea is accompanied by organic lesions of reproductive organs， often associated with local lesions of reproductive organs， but also with patients' mental factors and neuroendocrine factors.The incidence of dysmenorrhea is as high as 73.8%， and there is no radical cure method， which has a great impact on the life， work and learning of patients. Chinese medicine essential oil widely exists in aromatic Chinese medicine， with antibacterial， antioxidant and anticancer activities. It can regulate neuroendocrine function， anti-inflammatory and analgesic effects， and improve mood by regulating the levels of prostaglandins， oxytocin and other hormones in the body and regulating the emotions of patients， there by alleviating dysmenorrhea to a certain extent. In recent years， many scholars have made more in-depth research on Chinese medicine essential oil in alleviating dysmenorrhea， but there is a lack of comprehensive collation of such studies. In this regard， the author has systematically sorted out the generation and classification of dysmenorrhea， the mechanism of action of essential oil of traditional Chinese medicine to alleviate dysmenorrhea and the application of essential oil of traditional Chinese medicine in the field of dysmenorrhea by consulting relevant literature in Chinese and foreign languages in recent years， so as to provide reference for the treatment of dysmenorrhea.

Objective: To prospectively explore the relationship between resting heart rate (RHR) and risk of new-onset heart failure. Methods: It was a prospective cohort study. People who attended the physical examination of Kailuan Group Company in 2006 and with complete electrocardiography (ECG) recordings were eligible for this study. A total of 88 879 participants aged 18 years old or more who were free of arrhythmia, a prior history of heart failure and were not treated with β-blocker were included. Participants were divided into 5 groups according to the quintiles of RHR at baseline (Q(1) group, 40-60 beats/minutes (n=18 168) ; Q(2) group, 67-70 beats/minutes (n=18 970) ; Q(3) group, 71-74 beats/minutes (n=13 583) ; Q(4) group, 75-80 beats/minutes (n=22 739) ; and Q(5) group,>80 beats/minutes (n=15 419) ) .The general clinical data and laboratory test results were collected. The outcome was the first occurrence of heart failure at the end of follow-up (December 31, 2016) .We used Cox regression model to examine the association between RHR and the risk of new-onset heart failure. Hazard ratio (HR) with 95% confidence intervals (CI) were calculated using Cox regression modeling. Results: Among the included patients 68 411 participants were male, mean age was (51.0±12.3) years old, and RHR was (74±10) beats/minutes. Statistically significant differences among the RHR quintiles were found for the following variables: age, gender, systolic blood pressure, diastolic blood pressure, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, fasting blood glucose, body mass index, the level of high-sensitivity C-reactive protein, education status, physical activity, smoking status, drinking status, history of diabetes, history of hypertension and history of use antihypertensive drugs (all P<0.01) . Higher RHR was linked with higher prevalence of diabetes, hypertension history, and higher systolic blood pressure, diastolic blood pressure and FBG levels (all P<0.01). After a mean follow-up of 9.5 years, the incidence of new-onset heart failure in Q(1), Q(2), Q(3), Q(4) and Q(5) groups was 1.60%(290/18 168), 1.36%(258/18 970), 1.80%(245/13 583), 1.76%(400/22 739) and 2.35%(362/15 419),respectively (P<0.01) . The person-year incidence of heart failure in Q(1), Q(2), Q(3), Q(4) and Q(5) groups was 1.7, 1.5, 1.9, 1.9 and 2.6 per 1 000 person-years respectively. Compared with the Q(2) group, multivariate analysis with adjustment for major traditional cardiovascular risk factors showed that HRs of Q(3),Q(4),and Q(5) group were 1.23 (95%CI 1.03-1.48, P<0.05) , 1.19 (95%CI 1.01-1.41, P<0.05) , 1.39 (95%CI 1.18-1.65, P<0.01) , respectively. In the absence of hypertension, diabetes, smoking and acute myocardial infarction, the Cox regression model showed that compared with Q(2) group, the HR of new-onset heart failure in Q(5) group was 1.58 (95%CI 1.02-2.45, P<0.05) . Conclusion: Increased RHR is associated with increased risk of new-onset heart failure in this cohort.
