Journal of Chinese Physician 2013;15(7):890-894
Objective To investigate the association between red blood cell distribution width (RDW) level and the change of cardiac function in patients with chronic heart failure (CHF) and explore its possible mechanism by studying the correlation between RDW and left ventricular ejection fraction (LVEF),left ventricular end-diastolic dimension (LVEDD),and high-sensitivity C-reactive protein (hsCRP),and uric acid(UA) in patients with chronic heart failure.Methods Two hundred and eighty patients were included in our study.Each patient received the examinations of echocardiography,electrocar diogram (ECG),blood routine,and blood biochemistry.According to the different LVEF,LVEDD and RDW,the patients were divided into groups A,B,C,and D,respectively.The groups were compared with each other.Results According to the different LVEF,from group A to group D,with a progressive decrease in LVEF,RDW level were increased gradually [(13.48 ± 0.85) %,(14.10 ± 1.46) %,(14.59 ±1.59)%,(14.75±1.42)%,F =12.698,P <0.01].There was significant difference among the four groups (P <0.01).RDW level correlated inversely with LVEF(r =-0.538,P <0.01).According to the different LVEDD,from group A to group D,with a progressive increase in LVEDD,RDW level increased gradually [(13.53 ±0.91)%,(14.12±1.42)%,(14.60±1.68)%,(14.76±1.39)%,F =12.276,P <0.01].There was significant difference among the four groups (P <0.01).RDW level correlated positively with LVEDD (r =0.343,P <0.01).In chronic heart failure patients,there were significant linear correlation between RDW and hs-CRP,LgUA (r =0.486,0.513,P <0.05).Conclusions RDW correlated with the change of cardiac function in patients with chronic heart failure.With a progressive decrease in LVEF and a progressive increase in LVEDD,RDW level increased gradually.RDW had a strong correlation with hs-CRP,LgUA.This indicates that RDW level increase may be related to the inflammation and oxidative reaction in patients with chronic heart failure.
2.SPERMICIDAL STUDY ON MANDELIC ACID IN VITRO
Journal of Xi'an Jiaotong University(Medical Sciences) 1982;0(04):-
Mandelic acid(MA). the hydrolysate of a compound extracted from the leaves of prunus Persica B, possesses a strong spermicidal effect in vitro. In this experiment. the International Planned Parenthood Federation screening method for spermicides was used. Dilutions of MA, between 0.8mg/ml and 3.3mg/ml, totally immobilized human spermatozoa in less than 1 min. When the lowest spermicidal concentrotions of MA and boric acid against human spermatozoa were compared, it was found that MA was 40 times more potent than boric acid.

Natamycin is a polyene macrolide antifungal antibiotic ,which is wide ly used in the food industry in order to prevent mould contamination .Biosynthe s is gene cluster of natamycin is discovered by the overall of progress in molecul ar biology of natamycin, including 16 open reading frames which includes the gen e for 26-member ring formation of natamycin (pimS0-pimS4 ) and the modifying gene s, and the function of the protein including polyketide synthases(PKSs)、PimD、P imJ、PimK were studied
6.Expression of TGF-βRⅡ and fibronectin in developing mouse kidney
Acta Anatomica Sinica 2010;41(2):281-284
ObjectiveTo observe the chronological and spatial expressions of transforming growth factor-β receptor typeⅡ(TGF-βRⅡ)and fibronectin (Fn )in developing mouse kidney and investigate the relationship between the expressions and kidney development. Methods Immunohistochemistry and Western blotting were used to observe and measure the expression of TGF-βRⅡ and Fn in embryos and postnatal mouse kidneys. Results The expression of TGF-βRⅡ was noticed in all stages of glomeruli, renal tubes and collecting ducts, and increased gradually with ages; The expression of Fn was noticed too in all stages of glomeruli, renal tubes and collecting ducts, except for the comma-shaped bodies, and also increased gradually with ages. Conclusion TGF-β and Fn might play an important role in the development and maturation of mouse kidney.

Objective To assess the chest X-ray radiographic findings in children with influenza A (H1N1) virus infection. Methods The chest X-ray radiographies in 67 children with influenza A(H1N1) virus infection were reviewed in this study. The chest radiographies were obtained 3-8 days after the onset of symptoms and for the follow-up. Results The abnormalities were bilateral in 53 patients and unilateral in 7 patients. The predominant radiographic findings were bilateral patchy consolidation (n=42) with rapid confluence in 10 patients, lobular consolidation (n=7) with interstitial hyperplasia in 1 patient 3 month later, diffuse consolidation (n=11) with interstitial hyperplasia in all patients after 3 month. ConclusionThe predominant chest X-ray radiographic findings are bilateral patchy consolidation and diffuse consolidation with interstitial hyperplasia afterward.

Objective To confirm the efficacy of the “Hourglass Pattern”of ultrasound-guided fascia iliaca compartment block (FICB). Methods Approved by the medical ethics committee,we selected 30 patients undergoing selective total hip arthroplasty (THA ) in our hospital between January and May 2014.Before neuraxial anesthesia,ultrasound-guided FICB was performed.After identification of the “Hourglass Pattern”(internal oblique muscle and the sartorius muscle),a catheter was inserted. The sheath between the fascia iliaca and the iliacus muscle was distended with 40 ml of 0.2% ropivacaine,and then a continuous infusion of ropivacaine at a rate of 10 ml /h was administered for 48 h.Loss of sensation in the distribution areas of the femoral nerve and lateral femoral cutaneous nerve within 30 min was recorded.Patients were interviewed at 4 h,8 h,12 h,24 h,36 h and 48 h after block for pain intensity.Patients’ satisfaction scores at 48 h after block and the occurrence of adverse events (infection,local anesthetic toxicity,hemorrhage and hematoma)was recorded. Results The successful rate of the block was 100% without any adverse events.The median of numerical rating pain scale (NRPS)was below 4 points at 4 h,8 h,12 h,24 h,36 h and 48 h after block,and the patients’satisfaction score was (8.0 ±0.9 )points at 48 h after block.No adverse events occurred. Conclusions Ultrasound-guided FICB by using the “Hourglass Pattern”technique can offer effective analgesia after THA.It’s a safe method and can be easily performed.

Objective To explore whether childhood abuse experiences predict higher levels of depression and lower levels of self-esteem for graduate students and examine the mediating role of social support between childhood abuse and mental health.Methods A sample of 907 graduate students were investigated with the Childhood Trauma Questionnaire (CTQ-SF),Perceived Social Support Scale (PSSS),Self-esteem Scale (SES) and Center for Epidemiological Survey Scale (CESD).Results The scores of childhood abuse,social support,self-esteem,and depression of graduate students were (33.88±9.35),(68.31±12.01),(36.62±4.80) and (35.85± 9.20).Childhood abuse was negatively correlated with self-esteem (r=-0.32,P<0.01),but positively correlated with depression (r=0.28,P<0.01),and negatively correlated with social support (r=-0.44,P<0.01).Social support was positively correlated with self-esteem (r=0.39,P<0.01),and negatively correlated with depression (r=-0.41,P <0.01).Examining the mediation model indicated that social support had a partial mediation effects(42%) on the relationship between childhood abuse and self-esteem,and social support had a partial mediation effects(54%) on the relationship between childhood abuse and depression.Conclusions The childhood abuse not only affects the graduate student's self-esteem and depression directly,but also can take the same effect by social support indirectly.
