Objective To study the influence of oxiracetam plus mouse nerve growth factor(mNGF) on serum lysophosphatidic acid 2(Lp-PLA2) and S 100B protein in patients with acute cerebral infarction.Methods 124 patients with acute cerebral infarction were randomly divided into the observation group (n =62 cases) and the control group(n =62 cases).The patients in the control group were treated through the conventional treatment,while the patients in the observation group were treated by oxiracetam plus mNGF on the basis of conventional therapy.They were treated for 21 days.Serum Lp-PLA2 and S100B were detected.Results The total effective rate of the observation group was 98.4％,which was significantly higher than 90.3％ of the control group (x2 =3.96,P ＜ 0.05).Serum LpPLA2 and S100B were decreased in two groups after treatment.Serum Lp-PLA2 and S100B in the observation group were lower than those in the control group(t =20.9091,3.7273,all P ＜ 0.05).Conclusion Oxiracetam plus mNGF can decrease serum Lp-PLA2 and mNGF in patients with acute cerebral infarction.

ObjectiveTo investigate the influence of atorvastatin on C-reactive protein (CRP) level and clinical prognosis for chronic cardiac insufficiency combined with paroxysmal atrial fibrillation patients.Methods One hundred and eight-six chronic cardiac insufficiency combined with paroxysmal atrial fibrillation patients were divided into observation group(93 cases) and control group (93 cases) by random number table.The control group was given conventional treatment such as cardiotonic and diuretic,while the observation group was given atorvastatin 20 mg one time/night for 1 year on the basis of conventional treatment.Before and after treatment,lipid,left atrial diameter,left ventricular ejection fraction (LVEF),CRP and clinical outcome were compared.Results Lipid levels of the control group were not significantly different before and after treatment(P ＞ 0.05 ).In observation group,the levels of total cholesterol (TC),low density lipoprotein-cholesterol (LDL-C) and highdensity lipoprotein-cholesterol(HDL-C) after treatment were improved compared with those before treatment [ (4.1 ± 0.6) mmol/L vs.(4.8 ± 0.6) mmol/L,(2.7 ±0.3) mmol/L vs. (3.5 ±0.5) mmol/L,(1.0 ±0.1) mmol/L vs. (0.9 ±0.1) mmol/L,P ＜0.05].After treatment,the levels of TC,LDL-C and HDL-C in observation group were improved compared with those in control group (P＜ 0.05 ).There was no significant difference in left atrial diameter and LVEF before and after treatment in two groups.The levels of CRP before and 1 month and 6 months after treatment were ( 15.2 ±3.8),(12.1 ±2.7),(9.9 ±2.8) mg/L in observation group,and (15.0 ±3.8),(14.0 ±2.9),(13.7 ±2.8)mg/L in control group,and there were significant differences between two groups 1 month and 6 months after treatment(P ＜ 0.05).The incidences of atrial fibrillation recurrence and conversion for persistent or permanent atrial fibrillation in observation group were significantly lower than those in control group [6.5％ (6/93) vs.21.5％ (20/93),6.5％ (6/93) vs.19.4％ ( 18/93 ),P ＜ 0.05 ].ConclusionAtorvastatin can reduce CRP level of chronic cardiac insufficiency combined with paroxysmal atrial fibrillation patients,and reduce and delay recurrence and progress of paroxysmal atrial fibrillation.

Objective To investigate the effect of the application of quality control theory in nursing of patients with acute cerebrovascular disease undergoing interventional therapy.Methods 64 cases of patients with acute cerebrovascular disease from November 2009 to October 2011 in our hospital undergoing interventional therapy were chosen as the research object.They were randomly divided into the control group and the observation group with 32 cases in each group.The control group was given routine care,while the observation group was given nursing intervention under the instruction of quality control theory.The hospital stay,complication rates,satisfaction and SAS score,SDS score between the two groups of patients were compared.Results The length of stay,complication rate,satisfaction degree,SAS scores and SDS scores after the intervention in the observation group were significantly better than those of the control group.Conclusions Application of the theory of quality control in nursing of patients with acute cerebrovascular disease has a better effect,demonstrating an evident advantage in reducing complications and improving patients' mental state.

In the planned economic system, the old ways of management of college students domitories have existed for tens of years. But there are some problems which hamper the training of creative and high-quality talents. After the socialization of university rear service, it is necessary to strengthen the management of students community, speed up its construction, improve the quality of campus culture and provide good services. This will be probed in the article.

Objective To investigate the choice of treatment of tubal pregnancy.Methods 128 patients with tubal pregnancy were randomly divided into 43 patients of drug group,42 cases of laparoscopy group,43 cases laparotomy group.The differences of pregnancy status,time to pregnancy,tubal smooth the situation,length of stay,discharge of blood β-HCG were compared.Results Lapamscopic surgery therapy whose intrauterine pregnancy rate reached 80.9%,one year intrauterine pregnancy rate was up to 66.7%,tubal flow rate was 78.6%,and the pregnancy and discharge time was significantly shorter,and the level of β-HCG decresaed when they would go out hospital.Conclusion Laparoscopic surgery therapy had small trauma,better pregnancy rate,low ectopic pregnancy rate,better tubal patency rate,and it could improve fertility,and make discharging quickly,and was an effective treatment for patients with tubal pregnancy.

ObjectiveTo find out the etiological factor characteristics and age composition of pericardial effusion,to improve clinical diagnosis and treatment,reduce the misdiagnosis rate. Methods73 pericardial effusion patients in our department were admitted by age into youth group, middle age group and elderly group, and the etiological factor characteristics and age composition of pericardial effusion were analyzed respectively. ResultsThe main pathogenic factors of 73 pericardial effusion patients were cancer, heart failure, tuberculosis, non-specific pericarditis, nontuberculous bacterial infections, as well as renal failure, pulmonary infection, trauma, myocarditis, acute myocardial infarction, collagen disease, hypothyroidism. There was statistically significant of etiological factors on the three groups (P ＜ 0.01 ). ConclusionPathogenic factors of pericardial effusion were affected by many factors, and the significant difference in age composition should be well focused in clinical practice.

Objective To analyse the clinical significance of serum homocysteine(Hcy) and neutrophil gelatinase‐associated li‐pocalin(NGAL) in patients with hypertensive nephropathy ,and explore the relationship between serum homocysteine ,NGAL con‐centration and Urinary albumin excretion rate(UAER) .Methods 103 patients with hypertension treated in renal and cardiovascular department of Huangshi Central Hospital from January 2012 to June 2014 were enrolled in the study and were divided into 3 groups :macroalbuminuria group (36 cases) ,microalbuminuria group (35 cases) and negative albuminuria group (32 cases) .In addi‐tion to that ,33 healthy people were recruited as control group .Serum homocysteine ,NGAL concentration and UAER were meas‐ured for the peple enrolled in the study .Results Serum homocysteine and NGAL concentration of macroalbuminuria group and mi‐croalbuminuria group were much higher than negative albuminuria group and control group(P<0 .05) .Serum homocysteine and NGAL concentrations compared between macroalbuminuria group and microalbuminuria group were significantly different (P<0 .05) .Serum homocysteine and NGAL concentrations of negative albuminuria group and control group were not significantly dif‐ferent(P>0 .05) .UAER was positively correlated with serum homocysteine and NGAL concentration(r=0 .792 ,0 .658 ,P<0 .05) . Conclusion The detection of serum homocysteine and NGAL are helpful in understanding the changes of disease in patients with hypertensive nephropathy .

Some new viewpoints are put forward by comparing the treatment of acupuncture syncope and the statement of its therapeutic effect in ancient and modern literature and in current textbooks and combining the authors’ understanding in clinical practice. Acupuncture syncope is not an acupuncture contraindication. If the body position is notaffected, the needles may not be withdrawn to avoid the consumption of qi. Clinical doctors should, on the one hand, pay attention to the therapeutic effect of acupuncture syncope in clinical practice and, on the other hand, not perform manipulations withstrong stimulation to blindly seek the therapeutic effect because acupuncture syncope has a more marked psychological effect on acupunctured persons.
