Correlations between lipid ratio/oxidative stress status in COPD patients and pulmonary hypertension as well as prognosis / 中南大学学报(医学版)

To investigate the correlations between lipid ratio/oxidative stress status in chronic obstructive pulmonary disease (COPD) patients and pulmonary hypertension as well as the prognosis.
 Methods: A total of 120 patients with COPD were randomly selected and served as the COPD group and 30 healthy persons were selected as the control group. The ratios of low density lipoprotein (LDL)/high-density lipoprotein (HDL), triglyceride (TG)/HDL and total cholesterol (TC)/HDL were measured. The superoxide dismutase (SOD) activity, malondialdehyde (MDA) content and total antioxidant capacity (T-AOC) level in the control group and COPD patients were detected. Pulmonary hypertension incidence and 3-year survival rate for COPD patients were statistically analyzed. Spearman rank correlation method was used to analyze relationship between lipid ratio /oxidative stress status and pulmonary hypertension.
 Results: Compared with control group, the ratios of LDL/HDL, TG/HDL and TC/HDL, and the serum MDA level in the COPD group were increased, while the serum SOD and T-AOC level in the COPD group were decreased; compared with stable period, lipid ratios and MDA levels in the acute period were elevated, while serum SOD and T-AOC levels were reduced (P<0.05). Pulmonary hypertension incidence and 3-year survival rates in the COPD group were 56.67% and 81.67% respectively; the lipid ratios and serum MDA levels in COPD patients with pulmonary hypertension were elevated compared with that in COPD patients without pulmonary hypertension; the serum SOD and T-AOC levels in COPD patients with pulmonary hypertension were reduced compared with that in patients without pulmonary hypertension (P<0.05). Spearman rank correlation analysis showed that ratios of LDL/HDL, TG/HDL and TC/HDL, and the serum MDA levels in COPD patients were positively correlated with 3-years pulmonary hypertension incidence (r=0.752, 0.748, 0.752, 0.748; P<0.05), and negatively correlated with 3-years survival rate (r=-0.722, -0.751, -0.736, -0.748; P<0.05); serum SOD and T-AOC levels in COPD patients were negatively correlated with 3-years pulmonary hypertension (r=-0.711, -0.734; P<0.05), and positively correlated with 3-year survival rate (r=0.726, 0.733; P<0.05). 
 Conclusion: Blood lipid ratio and oxidative stress levels in COPD patients are elevated while antioxidant abilities were attenuated. The lipid ratio and oxidative stress status in COPD patients is closely related to the prognosis of pulmonary hypertension. Therefore, blood lipid ratio and oxidative stress status may be used in evaluation of pulmonary hypertension and prognosis for COPD patients.

Relationships Between Blood Levels of Osteopontin, Brain Natriuretic Peptide and Cardiac Function in Patients With Degenerative Heart Valve Disease / 中国循环杂志

Objective: To explore the relationships between blood levels of osteopontin (OPN), brain natriuretic peptide (BNP) and cardiac function in patient with degenerative heart valve disease (DHVD). Methods: Our research included in 2 groups: DHVD group,n=120 relevant patients treated in our hospital from 2013-12 to 2015-02 and Control group,n=30 healthy subjects from physical examination in the same period of time. Based on blood levels of OPN, DHVD patients were further divided into 2 sub-groups as Normal OPN sub-group, the patients with 18.8 ng/ml ≤OPN≤ 30.0 ng/ml,n=35 and High OPN sub-group, the patients with OPN>30.0 ng/ml,n=85. OPN levels at prior treatment (T0) and 3 days (T1), 1 week (T2), 2 weeks (T3) after treatment were compared between DHVD group and Control group; BNP levels, cardiac outcome (CO), cardiac index (CI) and left ventricular ejection fraction (LVEF) were also compared. The relationships between blood levels of OPN, BNP and cardiac function in DHVD patients were studied by Pearson correlation analysis. Results: Compared with Control group at T0 time point, High OPN sub-group showed increased blood levels of OPN and BNP, while decreased CO, CI and LVEF. Compared with Normal OPN sub-group, High OPN sub-group had the higher levels of OPN and BNP at all 4 time points, while lower levels of CO, CI and LVEF. In DHVD group, compared with T0 time point, OPN and BNP levels were decreased at T2 and T3 time points, while CO, CI and LVEF were increased, allP<0.05. Pearson correlation analysis presented that in DHVD patients, blood levels of OPN were positively related to BNP (r=0.936,P=0.00) and negatively related to CO, CI and LVEF (r=-0.869,r=-0.884 andr=-0.858 respectively, allP=0.00). Conclusion: DHVD patients had increased blood level of OPN which is related to BNP level and cardiac function; this might be because of OPN promoting heart valve calciifcation, inlfammatory reaction and myocardial injury. OPN could be used as a reference index for evaluating the cardiac function in DHVD patients.

Plasma level of chemerin in COPD patients and the relationship between chemerin and lipid metabolism / 中南大学学报(医学版)

OBJECTIVE@#To explore the change of plasma level of chemerin in chronic obstructive pulmonary disease (COPD) patients and its relationship with lipid metabolism. 
@*METHODS@#A total of 150 COPD patients were randomly selected and set as the COPD group and 30 healthy persons were set as the control group. The COPD group was further divided into a thin group (BMI<18.5 kg/m2, n=116) and a normal weight group (BMI≥18.5 kg/m2, n=34) according to their body mass index (BMI). Enzyme-linked immunosorbent (ELISA) was used in detection of plasma chemerin, total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), and high-density lipoprotein (HDL). The hospitalization rate in a half year and the mortality was statistically analyzed. Pearson correlation analysis was applied to analyze the relationship between plasma level of chemerin and levels of blood lipids, and Spearman rank correlation method was used to analyze the relationship between the plasma levels of chemerin or lipids and the prognosis. 
@*RESULTS@#Compared with the control group, plasma levels of TC, TG and HDL in the COPD group in acute exacerbation and remission stage were reduced, while plasma levels of chemerin and LDL was elevated; compared with the thin group, plasma levels of TC, TG and HDL in the normal weight group were elevated, while plasma levels of chemerin and LDL were decreased. The hospitalization rate in half year and the mortality in the thin group were higher than that in the normal weight group, and the plasma levels of TC, TG and HDL in the COPD patients with hospitalization in half year or death were lower than that in COPD patients without hospitalization, while the plasma levels of chemerin and LDL was increased (P<0.05). Pearson correlation analysis showed that plasma level of chemerin in COPD patients was negatively correlated with plasma levels of TC, TG and HDL (r=-0.695, -0.748, -0.695, P<0.05), while positively correlated with plasma levels of LDL (r=0.668, P<0.05). Spearman rank correlation analysis showed that plasma levels of TC, TG and HDL in COPD patients and hospitalization rate in half year as well as the mortality were negatively correlated (TC: r=-0.716, -0.737; TG: r=-0.748, -0.753; HDL: r=
-0.736, -0.728, P<0.05), while the plasma level of chemerin or LDL and hospitalization rate in half year and the mortality were positively correlated (chemerin: r=0.753, 0.766; LDL: r=0.742, 0.755, P<0.05).
@*CONCLUSION@#Plasma levels of chemerin in the COPD patients are correlated with lipid metabolism. Plasma levels of chemerin and lipid are related to prognosis of COPD. The plasma levels of chemerin in patients with COPD may reflect the lipid metabolism and could be served as the index for prognostic evaluation.

Clinical and pedigree analysis of late onset congenital ornithine transcarbamylase deficiency in a child / 中华内分泌代谢杂志

Objective To raise the awareness of congenital ornithine transcarbamylase deficiency (OTCD) by analyzing the clinical features and the family pedigree in a child with OTCD.Methods Clinical characteristics were analyzed in a child with OTCD.The genetic analysis was performed in ten exons and nine intron-exon boundaries in the ornithine transcarbamylase (OTC) gene of the case and his family by direct sequencing of PCR-DNA from peripheral blood.Family history including his grandparents and uncle was registered.Results The onset age of the case was 6 months old,the clinical picture was characterized by recurrent episodes of vomiting,low spirits,hyperammonemia,and abnormal liver function.His brother died of the similar performance at 6 months old.His sister was healthy.IVS1-2A＞G intron mutation of OTC gene was found in the case,while his mother and sister were the carriers and his father revealed no mutation.His maternal grandparents and his uncle's family were healthy.Conclusion OTCD is a kind of congenital genetic disease,and is one of the main causes of hyperammonemia.Misdiagnosis is very common because clinical symptoms of this disease are variable.IVS1-2A＞G mutation in OTC gene is the pathogeny of this case.The family genealogy indicates that this case is a kind of X-linked recessive hereditary disease.

Simple evaluation on combined wound with seawater immersion / 中国组织工程研究

BACKGROUND: To establish experimental animal model for rapid evaluation of combined wound with seawater immersion so as to benefit wound healing and recovery.OBJECTIVE: To explore the plan of simple evaluation of combined wound with seawater immersion.DESIGN: Group division and controlled experiment was designed.SETTING: Second Department of Orthopaedics, the 113 Hospital of Chinese PLA; Research Institute of Surgery, Daping Hospital, Third Military Medical University of Chinese PLA MATERIALS: Totally 32 health hybridized adult dogs were employed,mass weighted varied from 12 to 15 kg, of either sex.METHODS: The experiment was performed partially in the specific sea area of the Fifth and Sixth Room , Research Institute of Surgery of Daping Hospital of the Third Military Medical University of Chinese PLA from October 2001 to June 2002. The dogs were randomized into burn-blast combined wound group and projectile-burn combined wound group and each group was subdivided into immersion group (10 dogs) and the control (6 dogs). Burn-blast combined wound group: The model of burn and mild blast injury was prepared. In the control, the dogs were put in a room at 25 ℃ directly after injury; But in immersion group, the dogs were immersed immediately in simulated seawater with holder. Projectile-burn combined wound group: The model of burn and mild projectile injury was prepared. The managements were same as the previous after injury in the control and immersion group. The change of physiologic indexes was observed in 28 hours after injury. The indexes related to death were picked up for correlative analysis and establishing wound scoring scale, inducing body temperature, heart rate, mean arterial pressure (MAP), chloride concentration, PaO2 and causative factor, 0-5 score were designed, the higher the score was, the higher mortality would be.MAIN OUTCOME MEASURES: ① Analysis of dead cases in each group. ② Wound scoring. ③ Verification of wound in scoring scale.RESULTS: 32 dogs all entered result analysis. ① Analysis of dead cases and relationship: Totally, 12 dogs were died. The peak of death was in 10-12hours, no matter the immersion happened or not. 5 indexes were associated significantly with death, named body temperature, heart rate, MAP, PaO2 and chloride concentration (P ＜ 0.05). ② Comparison of wound scoring, predictive mortality and actual mortality in each group: The results in burn-blast control were (5.89±3.25) score, 0 and 17% successively. Those in projectileburn control were (6.78±2.02), 25% and 33% successively. Those in burn blast immersion group were (9.50±4.20) scores, 50% and 30% and those in projectile-burn immersion group were (11.13±3.57) scores, 50% and 60%.CONCLUSION: ① The established scoring scale is apt to obtain common physiological indexes so as to evaluate the wound rapidly, which is applica ble for either seawater immersed cases or non-immersed cases, indicating extensively applications. ② The correction of evaluation is acceptable with verification. ③ The scale is based on animal experimental data, for which,it is still different from the one of real wound evaluation.
