1.Nutrition status of acute stroke patients with hypothyroidism
Chinese Journal of Clinical Nutrition 2009;17(2):98-100
Objective To evaluate the nutrition status and the prognosis of acute stroke patients with hy-pothyroidism during hospitalization. Methods The clinical data of 28 acute stroke patients with hypothyroidism (study group) and 28 stroke patients with normal thyroid function (control group) were retrospectively analyzed.Results After (10±4) days of hospitalization, hemoglobin and serum albumin levels in study group significantlydecreased ( P < 0. 05 ). The requirement of calories and protein, incidence of pulmonary infections, alimentarytract hemorrhage and diarrhea, and hospital stays were significantly higher in study group than in control group (P < 0. 05 ). Conclusion The nutrition status is poor in acute stroke patients with hypothyroidism, who were more easier to be suffered from clinical complications and worse prognosis.
2.Progress in the role of hydrogen sulfide in inflammation
International Journal of Pediatrics 2010;37(2):212-214
Hydrogen sulfide (H2S) was considered as the third gasotransmitter,along with nitric oxide and carbon monoxide,with extensively biological activities.Considerable evidence showed that H2S was involved in inflammatory processes such as in inflammatory cells,inflammatory mediates,vascular tension and signaling pathways.Previous studies suggested H2S played a bidirectional role in regulating inflammation including pro- and anti-inflammatory actions due to different animal models.Further study about the role and mechanism of H2S in inflammation will contribute to efficient prevention and treatment for inflammatory diseases.

4.Relationships between the polymorphism of methylenetetrahydrofolate reductase gene C677T and hypertension,cardiac structure and function
Medical Journal of Chinese People's Liberation Army 2001;0(07):-
Objective Elevated plasma homocysteine(Hcy) level has been associated with the increased risk for cardiovascular disease.The level of plasma Hcy is related to methylene tetrahydrofolate reductase(MTHFR) gene C677T polymorphism.The aim of this study is to evaluate the relationships between MTHFR gene C677T polymorphism and hypertension,cardiac structure and function.Methods Genotype of MTHFR gene C677T polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) analysis and decided by electrophoresis and sequencing in 695 patients with essential hypertension and 509 age-matched normal controls.Echocardiography was performed in patients with essential hypertension.Results In hypertension group,the frequencies of TT genotype and T allele were significantly higher than those in control group(26.5% vs 20.6%,48.7% vs 42.4%;P=0.015,0.002).The essential hypertension odds ratio(OR) associated with MTHFR 677T allele was 1.300(95%CI:1.166 to 1.450).Logistic regression analysis indicated that MTHFR gene C677T polymorphism was an independent variable of hypertension(P=0.027).End diastolic dimension(EDD),interventricular septal thickness(IVST),left ventricular posterior wall thickness(LVPWT),left ventricular mass(LVM) and left ventricular mass index(LVMI) were higher in hypertensive patients with T allele than that in those with CC genotype,but all had no statistical significance(P=0.428,0.118,0.064,0.077,0.054).Conclusion The 677T allele in MTHFR gene may be a risk factor for hypertension.Hypertensive patients with MTHFR 677T had a trend of hypertrophy,but the relationship has no statistical significance.The relationship between MTHFR gene C677T polymorphism and left ventricular hypertrophy need to be further studied.

8.Application of beta blockers in the treatment of patients with heart failure
Chinese Journal of Practical Internal Medicine 2001;0(03):-
Beta blocker can be categorized by non-selective agents,selective agents and agents with vasodilatory effect.Beta blocker therapy represents a major advance in the treatment of heart failure patients.The mechanisms include up-regulation of beta receptor,reversing remodeling,improving contractile and diastolic function,antiarrhythmia and anti-ischemia.Evidences from randomized controlled clinical trials have supported its use in the treatment of patients with heart failure to decrease mortality and improve life quality.Guidelines with various versions recommend that ?-blockers are indicated for patients with symptomatic or asymptomatic heart failure and a depressed ejection fraction of lower than 40%.There is something to be noticed for rational use of ?-blockers such as timing,dosage,duration and contraindications.

Journal of Traditional Chinese Medicine 1993;0(02):-
Objective To study the mechanism of reinforcing kidney and activating blood therapy for the apoptosis of endometriosis.Methods Female SD rats aged 8~12weeks were grouped as model group,western medicine group,Chinese medicine group and integrated Chinese and western medicine group,with 15 in each group.The light microscope,electron microscope,TUNEL method,and immunohistochemical method were adopted to observe the pathomorphology,positive rate of apoptotic cells and the positive expression of apoptosis-regulating gene bcl-2 and bax.Results The apoptosis of endometriosis tissues in the integrated Chinese and western medicine group was the most obvious result with the highest apoptosis index,and the positive expression of apoptosis regulating gene bcl-2 was downward regulated and that of apoptosis regulating gene bax upward regulated,so bcl-2/bax decreased.Then it was Chinese medicine group,western medicine group,and model group.Conclusion The occurrence of endometriosis is related with the lowering of ability of apoptotic cells.Chinese medicines with the functions to reinforce kidney and activate blood can promote the ability of apoptotic cells in endometriosis to quicken the atrophy and regression of endometriosis tissues.

Chinese Journal of Geriatric Heart Brain and Vessel Diseases 2014;(10):1032-1034
Objective To assess whether urapidil (anα1 receptor blocker)is more effective than ni-troglycerin in treatment of non-valvular heart failure accompanying hypertension and diabetes mellitus (DM ) in elderly female patients .Methods Fourty-six elderly female patients with non-valvular heart failure accompanying hypertension and DM were randomly divided into urapidil treatment group (n= 24) and nitroglycerin treatment group (n= 22) .Patients in urapidil treat-ment group were treated with urapidil (50 -300 μg/min) and those in nitroglycerin treatment group were treated with nitroglycerin (5 -20 μg/min) for 48 -140 h according to their blood pressure (BP) and cardiac function .Their BP ,HR ,and metabolic activity were observed before and on days 1 ,2 ,3 and 7 after treatment .Results The effect of urapidil was significantly lower than that of nitroglycerin on SBP on day 7 after treatment (P<0 .05) .The serum NT-proBNP level was significantly lower in nitroglycerin treatment group than in control group (P<0 .01) . Conclusion The effect of urapidil is better than that of nitroglycerin on reducing and stabilizing SBP ,attenuating cardiac afterload ,and improving cardiac function in elderly female patients .Ura-pidil can thus be used as one of the first choiced drugs in treatment of elderly female patients with non-valvular heart failure accompanying hypertension and DM .
