Objective To study seasonal variation of blood pressure (BP) in patients with essential hypertension (EH) and its association with meteorological elements. Methods In total, 1800 patients with essential hypertension were recruited by cluster sampling from three townships and towns in Qingzhou,Shandong province, 1155 men and 645 women, with an average age of 61.3 years (ranging from 29 to 85years). BP was measured for all of them in sitting position at 8:00 in the morning every seven to 14 days during July 2008 to June 2009. Local meteorological data were collected accordingly such as temperature,humidity and atmospheric pressure, and multivariate regression analysis was performed to show their association. Results In general, BP in patients with EH presented a decreasing trend during the first half year of observation, with the lowest in the summer ( May to August). From September to October, their BP began to increase gradually, and reached the peak in the winter ( November to February nest year). There was significant difference in systolic BP (SBP) and diastolic BP (DBP) between various seasons (Pspring-summer = 0.002 and 0.000, Pwinter-spring = 0.001 and 0.000, Psummer-autumn = 0.045 and 0.000,Psummer-winter =0. 000 and 0. 000, Pautumn-winter =0. 000 and 0. 000, respectively), except for those between the spring and autumn. Both SBP and DBP reversely associated with outdoor air temperature and room temperature(beta= -0.08, t = -2.39, P ＜0.05 and beta = -0.24, t = -6.21, P ＜0.01,respectively), (beta = -0.08, t = -2.39, P ＜0.05 and beta = -0.24, t = -6.21, P ＜0.01,respectively). Conclusions BP in patients with EH reveals seasonal variation, with the lowest in the summer and the highest in the winter and evident fluctuation in the spring and autumn, especially in SBP,which associates with room temperature and their blood vessel elasticity.

Objective To investigate the effect of arthroscopic debridement and meniscectomy in treatment of moderate or severe meniscus injury combined with knee osteoarthritis in early or middle stage. Methods 156 cases diagnosed with moderate or severe meniscus injury combined with knee osteoarthritis in early or middle stage were collected from October 2011 to October 2014. Lysholm knee score and preoperative examinations such as anteroposterior, lateral, axial radiographs, the standing full leg length X-ray film and MRI scan of the knee were recommended to definitively understand the osteoarthritis staging and meniscus injury grading. All patients were treated with arthroscopic debridement and meniscectomy. After operation, physical rehabilitation exercises and regular clinical follow-up were carried out as planned. The Lysholm knee score data from preoperation and terminal follow-up was statistical analyzed. Results No patient experienced any perioperative and postoperative complications. Statistical analysis showed that the Lysholm knee score of postoperation was significantly higher than that of preoperation [(87.3 ± 7.9) vs (67.5 ± 4.9), P < 0.05). Conclusion Arthroscopic debridement and meniscectomy in treatment of moderate or severe meniscus injury combined with knee osteoarthritis in early or middle stage, gains beneficial effects for its minimal invasion and quick recovery.

Non-invasive (NI) blood glucose measurement is a new method, this article deals with current researches and analyzes the advantages and shortages of different measurement methods, including electrochemical process and Optical methods (transmission, polarimetry and back scattering). Then, the technology of near-infrared spectra is emphasized in the analysis. Finally, the problem and technical analysis of non-invasive (NI) blood glucose measurement at the present time are discussed. We preliminarily aim at the method of NI blood glucose determination and the original concept of measuring apparatus, including the choice of incident light wavelength, determination of receiver point, establishment of the optical model of biological tissue, and apparatus design.

Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Most patients with sepsis underwent a state of immune suppression after surviving the acute inflammatory response, and were susceptible to secondary nosocomial infections, leading to a prolonged hospitalization and increased mortality rate. Myeloid-derived suppressor cells (MDSCs), a heterogeneous population with immunosuppressive activities, can contribute to the development of immunosuppression in patients with cancer and inhibit the host immune response, but the characteristics of MDSCs and their functional mechanism has not been fully addressed in the development of sepsis-induced immunosuppression. Thus, this review will summary the new findings on the mechanisms of MDSCs in septic immunosuppressionin order to provide ideas and directions for targeting MDSCs as treatment of septic immunosuppression.
