Objective To discuss the major cardiovascular disease(CVD) risk factors and volume load of women.Methods A cross-sectional study was conducted on adult women who came to our hospital for health examination.The clinical data included age, past medical history, smoking history, drinking history, body measurements (height, body weight, blood pressure, etc.), and blood serum creatinine, hemoglobin, blood glucose, blood lipid and other biochemical indicators were detected.Using the human body composition analyzer, the extracellular fluid (ECW), intracellular fluid (ICW), total water(TBW), and ECW/TBW ratio (E/T) were used to evaluate the capacity of the cells.Total body water(TBWwatson) was Calculated according to Watson formula.The clustering of four major CVD risk factors (defined as two or more of the following: hypertension, diabetes, dyslipidemia and overweight) and their association with volume load were investigated.Volume load was evaluated by bioelectrical impedance analysis.Hypovolaemia was defined as extracellular water/total body water (ECW/TBW) at and under the 10 percentile for the normal population.Logistic regression model was use to explore the relationship between capacity status and risk factors of CVD.Results A total of 2 433 women (mean age (37.4±7.3) years old) were enrolled in the study, 14.7％ of them had clustering of CVD risk factors.Hypovolaemia in clustering group was statistically higher than either in the single or in the none risk factor group, which was 18.2％, 11.9％, 6.7％, respectively (x2 =45.4, P＜0.001).After adjusted for potential confounders (including age, hemoglobin, serum uric acid, estimating glomerular filtration rate (eGFR), hypovolaemia was associated with clustering of CVD risk factors, with an OR of 2.76 (95％ CI 1.93-3.95).Conclusion Hypovolaemia is associated with clustering of major CVD risk factors in women, which further confirms the importance of modifying lifestyle to reduce the burden of CVD.

The inspiratory impedance threshold device (ITD) was put forward by Lurie in 1995, and was assigned as a class II a recommendation by the International Liaison Committee on Resuscitation (ILCOR) resuscitation guidelines in 2005. The ITD is used to augment negative intrathoracic pressure during recoil of the chest so as to enhance venous return and cardiac output, and to decrease intracranial pressure. In the recent years many researches on the ITD have been1 carried out, but all the researches can not take out a clear evidence to support or refute the use of the ITD. This paper introduces the structure and working principle of the ITD in detail, the research results and the debates about the use of the ITD for the past years.

OBJECTIVETo observe the effect of detoxifying and blood circulation activating Chinese herb extraction of polygonum cuspidatum and hawthorn on carotid intima-media thickness (IMT), plaque integral and plaque stability related serum indexes of patients with carotid atherosclerosis.

METHODSixty and four cases of carotid artery atherosclerosis patients were assigned randomly to 2 groups: detoxifying and blood circulation activating treatment group (treatment group, 32 cases) and control group (32 cases). Patients in treatment group were treated with capsules of extraction of polygonum cuspidatum and hawthorn, 1 pill po, bid (dosage of administration: polygonum cuspidatum extraction 5.33 mg x kg(-1) x d(-1), hawthorn extraction 5.0 mg x kg(-1) x d(-1)); patients in control group were treated with lovastatin 20 mg po, qd (dosage of administration: 0.33 mg x kg(-1) x d(-1)). The course of treatment was six months. To observe changes of IMT, plaque integral, and detect the level of plaque stability related serum indexes such as Hs-CRP, MMP-1 and TIMP-1.

RESULTAfter 6 months of treatment, in control group one patient quit the clinical trial because of liver dysfunction and one patient was rejected because of having not followed the therapeutic regimen. 32 cases in treatment group and 30 cases in control group were analyzed. The results showed that IMT and plaque integral of treatment group decreased significantly after the treatment (P < 0.05, P < 0.01), and there was no significant difference compared with control grope. Serum Hs-CRP, MMP-1 and MMP-1/TIMP-1 decreased after the treatment (P < 0.05, P < 0.01), and the treatment group was superior to control group in decreasing serum Hs-CRP (P < 0.05).

When looking back to the literature regarding insomnia, it is believed that "disharmony of stomach leads to insomnia" is an important mechanism for the attack of insomnia. This theory is widely accepted in clinical practices by ancient and modern acupuncturists, thus the method treating insomnia from the stomach is developed. But deeper research on its mechanism is still lacking. Through correlation between stomach meridian and heart meridian, spleen and stomach being the pivot of rise and decline of qi movement and yin-yang and being the pivot of five zang-viscera housing spirit, modern abdomen-brain theory and experimental research, the mechanism of treating insomnia from the stomach is discussed in this paper, so as to be better to guide clinical acupoint-selection and treatment.
