Objective To investigate the correlation between red blood cell distribution width (RDW) and urinary protein /cre-atinine ratio(TPCR) in elderly patients with essential hypertension .Methods TPCR ,Cr ,CysC ,eGFR ,TG ,TC ,LDL-C ,ApoA1 , ApoB and blood routine were detected in 801 elderly patients with essential hypertension and 98 healthy people .The differences of these indexes were compared between the two groups and the difference of RDW was compared among different grades of hyperten-sion .The hypertension patients were divided into two groups by TPCR<200 mg/g Cr or ≥200 mg/gCr ,the levels of RDW were compared between the two groups and the correlation between TPCR with RDW was analyzed .Results The age ,gender ,Cr and HB had no statistical differences between the hypertension group and control group (P>0 .05);TPCR ,TG ,TC ,LDL-C ,ApoB and RDW levels in the hypertension group were increased ,the ApoA1 ,CysC and eGFR levels were decreased ,the differences were sta-tistically significant (P<0 .05);the RDW level in the hypertension group was significantly higher than that in the control group ,the difference was statistically significant(P<0 .05);the RDW level was increased with the increase of blood pressure level ,the differ-ence was statistically significant(P<0 .05);the Pearson correlation analysis showed that RDW was positively correlated with TPCR (P<0 .05) .Conclusion The RDW level is elevated in the essential hypertension group ,and correlated with the level of TPCR .

Objective To evaluate the role of using non-invasive ventilation with bi-level positive airway pressure (BiPAP) in order to reduce the need of re-intubation in pediatric patients with respiratory failure after cardiac surgery. Method From January 2007 to December 2007, 25 patients aged from three months to 11 years with median 2.3 years operated on for cardiac surgery with respiratory insufficiency after extubation and re-intubation indicated were enrolled in this study. They were put on non-invasive nasal (mask) BiPAP ventilation before re-intubation. The arterial blood gas, A-aDO2 and PaO2/FiO2 were measured. In addition, clinical data including heart rate, respiratory rate, and the product of heart rate and systolic pressure were recorded before and after BiPAP. The software SPSSD 13.0 was used to process by ANOVA test for statistical analysis. Meanwhile, the outcome of these patients was analyzed. Results Twenty-five patients with 30 episodes of respiratory insufficiency were treated with BiPAP ventilation with median duration of 1.96 days ranged from 0.03 to 12 days. Of these respiratory failure episodes, 25 ones (83.3%) could be controlled by BiPAP and the needs of re-intubation were avoided. Five episodes of respiratory failure in 4 patients could not be quelled and the endo-tracheal tubes were inserted in these patients. All patients were saved with a median of mechanical ventilation duration of 3.4 days and ICU stay of 10.6 days. No major complications were observed. The heart rate, respiratory rate and the rate-pressure product were decreased significantly one hour after BiPAP (P < 0.05 all). Meanwhile, patients showed rapid improvement of oxygenation. The pH, SpO>2 and PaO2/FiO2 were increased significantly and A-aDO2 was decreased significantly (P < 0.05 all). The PaCO2, was decreased significantly four hours after BiPAP (P < 0.05). Conclusions Non-invasive nasal mask BiPAP can be used safely and effectively in children after cardiac surgery to improve oxygenation/ventilation, decreasing the work of breathing. It may be particularly useful in patients with high risk of re-intubation.

As one of the important founders of GAO's acupuncture academic school in YanZhao area, Professor GAO Yuchun 's experience of acupuncture for headache is summarized in this paper. In the opinion of Professor GAO, the treatment of headache should focus on eliminating evil and relieving pain, and the syndrome differentiation should be based on meridian differentiation, especially on three yang meridians of foot as well as liver meridian and kidney meridian. In the acupoint prescription, attention should be placed on strengthening the spleen and stomach. The midnight-midday ebb flow acupuncture is advocated. The combination between acupuncture order and movement of qi is emphasized. In the manipulation, the role of pressing hand, the stimulation during reinforcing and reducing methods, and needle-retention time are important. The breathing reinforcing and reducing method of acupuncture are also advocated.

Objective To evaluate protective effects of hypothermic pulmonary protective solution with uli-nastatin on lung function during cardiopulmouary bypass (CPB) in the patients with congenital heart disease(CHD) and pulmonary hypertenion. Method Fifty-four children,who had CHD of left-to-fight shunts with moderate-se-rious pulmonary hypertension, were enrolled. They had been performed with the radical operation under CPB from September 2005 to December 2006 in the Department of Cardiovascular Surgery, Children' s Hospital of Zhejiang University. Moderate-serious pulmonary hypertension was defined as pulmonary-to-systolic pressure ratio > 0.45(Pp/Ps > 0.45). Fifty-four children were randomly divided into three groups. Patients in group A (n = 18)didn't receive pulmonary protective solution, and scrved as control; patients in group B (n = 18) were adminis-tered with pulmonary protective solution without ulinastatin;patients in group C (n = 18) were administered with pulmonary protective solution with ulinastatin. The serum concentrations of MDA and MPO were measured at five different time points:pre-operation, 0 h, 3 h, 6 h and 24 h in the intensive care unit (ICU) (T1～5). Patients'lung functions were monitored at T1 - T4. The time of mechanical ventilation was recorded. Results No one died in this study. The mean time of mechanical ventilation was shorter in the group B and group C than that in the group A. The MDA and MPO levels were lower in group B compared with group A at T4. The MDA level at T3-T5 and the MPO level at T4 was lower in group C than those in group A. There were no significant in MDA and MPO levels between group B and group C at five time point.A-aDO2 was lower in groups B and C than those in group A at T3 and T4, whereas at T4, A-aDO2 was lower in group C than that in group B. Cdyn was higher in group B at T3and group C at T3 - T4 than those in group A. Cdyn was lower in groups C than that in group B at T4.Condusions Lung perfusion with hypothermic protective solution during CPB can all lung injury and promote recovery after operation, especialy with ulinastatin.

Objective To analyze the infection features,risk factors,and the relationship with the efficacy in patients with acute leukemia during initial induction chemotherapy.Methods The clinical data of 200 patients with newly diagnosed acute leukemia from January 2015 to February 2016 in the Second Hospital of Shanxi Medical University were retrospectively analyzed.Results The infection rate of patients with acute leukemia under induction chemotherapy was 84.0％ (168/200).Among 168 patients with infection,159 cases (94.6％) had known infection sites,the top three infection sites were the lungs,gastrointestinal tract and the oral cavity.Total 213 strains of pathogens were identified,Gram-negative bacilli accounted for 39.0％ (n =83),Gram-positive cocci for 34.3％ (n =73),fungi for 23.5％ (n =50) and the virus for 3.3％ (n =7).Multivariate regression analysis showed that agranulocytosis was the independent risk factor for acute leukemia patients during induction chemotherapy (OR =14.370,95％ CI:2.576-116.518,P ＜ 0.01).The rate of complete remission (CR) and CR with incomplete hematologic recovery (CRi) in infection group was 74.4％ (125/168),and the rate of CR + CRi in non-infected group was 87.5％ (28/32),and there was no significant difference between the two groups.(χ2 =2.564,P =0.109).Conclusion During the induction therapy for acute leukemia patients,the rate of infection and the rate of fungal infection are high;lung is the most common site,Gram-negative bacteria is more common;agranulocytosis increases the chance of infection;and the infection may not affect the disease remission rate.

Chitosan (CS) is a natural,non-toxic biopolymer mainly made from the deacetylation of chitin. Chitosan has good bio-compatibility with unique antioxidant and biodegradable properties. Due to the poor solubility of chitosan in neutral or alkalinized media,the application of chitosan is restricted. Thus,numerous chitosan derivatives have been developed through chemical modifica-tions to broaden the application scope and improve its value. Chitosan and its derivatives with antioxidant activity have shown superior medical value in recent years. In this paper,several modification methods of chitosan were reviewed. In addition,the research progress in chitosan and its derivatives as antioxidants was introduced.
