Objective: To understand the situation of blood pressure control and its influencing factors in elderly patients with hypertension in Hangzhou, and to provide basis for the management of elderly patients with hypertension in community. Methods: The subjects of this study were hypertension patients aged 60 years and over in Hangzhou community health management of basic public health services. Demographic data and life behaviors were collected by a questionnaire survey, physical examination and laboratory tests were carried out. The multivariate logistic regression model was used to analyze the influencing factors for blood pressure control in elderly patients with hypertension. Results: A total of 109 583 people were investigated, with 50 500（46.08%） males and 59 083（53.92%） females. The control rate was 47.70% ( 52 273/109 583 ). After adjusted for age and gender, regular medication ( OR=0.874, 95%CI: 0.838-0.912 ) was the protective factor, obesity ( OR=1.291, 95%CI: 1.260-1.324 ), abnormal fasting plasma glucose ( OR=1.218-1.344, 95%CI: 1.178-1.410 ), the number of unhealthy lifestyles ( OR=1.271-1.292, 95%CI: 1.231-1.344 ), the items of dyslipidemia ( OR=1.047-1.253, 95%CI: 1.017-1.311 ), and the number of cardiovascular risk factors above ( OR=1.254-2.109, 95%CI：1.175-2.281 ) were the risk factors for blood pressure control in elderly patients with hypertension. Conclusions The control rate of elderly patients with hypertension in Hangzhou is 47.70%, which is associated with irregular medication, unhealthy lifestyle, obesity, dyslipidemia, abnormal fasting plasma glucose and clustering of these factors.

Objective To discover new biomarkers for diffuse large B-cell lymphoma (DLBCL) diagnosis and prognosis using nuclear magnetic resonance (NMR)-based serum metabolomics. Methods High-resolution serum 1H NMR spectra were collected from 7 DLBCL patients and 7 healthy controls. Spectra were processed using stoichiometry pattern-recognition methods [principal component analysis (PCA) and orthogonal partial least squares discrimination analysis (OPLS-DA)]. Results Significant difference (P <0.05) in 9 metabolites was observed between DLBCL and healthy control by OPLS-DA (variable interpretation rate R2Y ＝ 99.0 % and prediction rate Q2＝ 94.5 %). Compared with the healthy control group, higher levels of lactate (r ＝0.60, P<0.01), glycine (r ＝0.84, P<0.001), creatine (r ＝0.63, P<0.01), and choline (r ＝0.69, P< 0.01), lower levels of acetate (r＝ -0.88, P< 0.001), high-density lipoprotein (r＝ -0.77, P< 0.001), citrate (r ＝-0.82, P<0.001), glutamine (r ＝-0.53, P<0.05) and phosphocholine/glycerophosphocholine (r ＝-0.62, P<0.001) were detected in the serum samples of DLBCL. Conclusion The results of this study offer an evidence for significant changes between DLBCL patients and healthy people in serum metabolite profiles utilizing NMR-based serum metabolomics.

Cerebral infarction, also known as ischemic stroke, is a cerebrovascular disease with high disability and fatality rate worldwide. Despite comprehensive rehabilitation therapy on neural function, considerable patients may still suffer from motor functional disabilities, which directly affect their quality of life, ability of daily life, as well as increase the economic burden of patients’ families and society. Therefore, promoting the recovery of motor function is particularly important in patients with cerebral infarction, and this requires more novel therapeutic options in clinical practice. Repetitive transcranial magnetic stimulation is a painless and non-invasive therapy. Accumulating evidences suggest that repetitive transcranial magnetic stimulation can effectively improve the motor function of hemiplegic limb after stroke, and thus improving the patients quality of life. At present, new progress has been made in the basic and clinical studies of repetitive transcranial magnetic stimulation treatment. This review summarized these advances in this field in order to be beneficial to clinical work.

With the progress of science and technology and the development of society, more and more chemical substances have been discovered and countless chemicals have been artificially synthesized, and the risk of exposure to some toxic chemicals by human beings has been greatly increased, resulting in the increasing incidence of acute poisoning, which has seriously endangered the public's physical health and life safety. As the poisoned patients are unconscious or refuse treatment when they are admitted to the hospital, it is difficult to understand the drug exposure history by asking the medical history, so the toxicity detection has become the key to the clinical diagnosis and treatment, and this paper briefly introduces some common toxicity detection methods in the clinic in the hope that it will bring help to the clinical doctors.
