Objective To investigate the relationship among electrocardiogram QRS complex duration,left ventricular ejection fraction( LVEF),N-terminal pro-brain natriuretic peptide( NT-proBNP)and their relation to New York Heart Association (NYHA)functional classification in patients with chronic heart failure(CHF),and observe the intervention effects of Shenfu injection(SFI)on patients with CHF. Methods A total of 72 CHF patients were randomly assigned to treatment group(36 cases)and control group(36 cases). Patients in the control group received standard care,and those in the treatment group received standard care plus 1. 0 mL·kg-1 ·d-1 of SFI in 5% glucose for two weeks. Before and after the treatments,the electrocardiogram QRS complex duration,LVEF,NT-proBNP were measured and NYHA functional classification was evaluated. Results Electrocardiogram QRS complex duration was negatively correlated with LVEF and was positively correlated with NT-proBNP and NYHA functional classification( P〈0. 05 ). After the treatment,the proportion of patients with NYHA classⅠ-Ⅱsignificantly increased and classⅢ-Ⅳsignificantly decreased in both groups. The treatment group was superior to the control group in reinstating cardiac function( P〈0. 05 ). After the treatment,electrocardiogram QRS complex duration and the levels of NT-proBNP were significantly descended and LVEF were significantly ascended in both groups(P〈0. 05). The level of NT-proBNP in the treatment group was significantly lower than in the control group(P〈0. 05),but electrocardiogram QRS complex duration and LVEF did not show significant difference. The prior-and post-treatment difference in electrocardiogram QRS complex duration and LVEF was more obvious in the treatment group than in the control(P〈0. 05). Conclusion The extension of electrocardiogram QRS complex duration is correlated with plasma NT-proBNP elevation and cardiac dysfunction,which can be used as a reference for disease progression or medication efficacy. SFI is effective on CHF of the yang-qi deficiency type.

Objective To investigate the pathological and physiopathological difference between the ruptured” and the “degenerated” typed lumbar disc herniation (RDH and DDH) by measurement of the pressure of the herniated lumbar disc both in the herniated site and in the nucleus pulposus during the surgery, combined with the clinical,light microscopical and immunohistochemical properties. Methods Fifty seven cases of lumbar disc herniation undergone operation in the Tianjin Medical University Hospital were included in this study. The patients were divided into 2 groups. 1) Rupture typed lumbar disc herniation in which the herniated chip of the lumbar disc separated from the parent disc and was squeesed or drew out easily when the superficial posterior longitudenal ligament and anulus fibrosis were opened in the herniated site. 2) Degenerated typed lumber disc herniation in which no herniated chip of the lumber disc escaped; the herniated material can not be taken out unless the disc was resected by the instrument. Before the herniated disc was incised, the intervertebral disc pressure was measured using GENERAA710 multifunctional monitor. Both the light microscopical and the immunohistochemical difference between the RDH and the DDH was studied. Results 1) In the herniated site, the pressure in the RDH is higher than that in the DDH(P0.05). 3) In the RDH, the pressure in the herniated site is higher than that in the nucleus pulposus (P0.05). 5) The“lumbar pain score”and the pressure have obviously relationship in all of 35 patients(r=0.539,P

Using the high efficient copper-adsorbing yeast strain Y17 as absorbing material, the major affect factors including pH, original concentration of Cu2+, cell biomass, adsorption time and temperature were examined, and then the absorbing sites of the Y17 was determined. The results showed that the solution pH was the most dominate factor which affected the biosorption of Cu2+, the other affecting factors were the ini- tial concentration of Cu2+, the cell biomass added, and adsorption time, respectively; the temperature had lit- tle effect on the rate of biosorption. The orthogonal experiment showed that the optimal absorption condition was as follow: the solution pH was 5.0, the absorption time was 40 min, the cell biomass of Y17 added was 5.0 g/L, and the concentration of Cu2+ was 8 mmol/L; the highest adsorbing rate was up to 82.7% at this condition. Based on the results of different pretreatments and the desorption of Cu2+, the cell wall of Y17 was identified as the main place occurring boisorption process, and the -NH2 group, -COOH group on the surface of the yeast cells played an important role on the boisorption process.

Objective To observe the anti-atherosclerosis effects of Guizhi Fuling Capsule. Methods 50 healthy SD male rats were randomly divided into 2 groups: normal group (n=12) and AS model group(n=38). The model of experimental AS rats was established by feeding high cholesterol diet and intraperitoneal injecting VitD3. The normal control group was fed by ordinary diet. AS model group was further divided into 3 groups randomly: AS group(n=12), control group (n= 12), and therapy group(n= 12). The therapy group was given Guizhi Fuling Capsule by intragastric administration.The control group was given simvastatin and captopril by intragastric administration. 0.9% NaCl was given to the AS group instead of Guizhi Fuling Capsule. The rats were killed at the 16th weekend, and their aorta arch and breast aorta were observed.Blood fat and serum levels of Endothelin-1 (ET-1), Nitric oxide (NO), high-sensitivity C-reactive protein (hs-CRP) were detected respectively. Immunohistochemistry technology was used for observing the expression of intercellular adhesion molecule- 1 (ICAM- 1 ) in breast aorta. Results The values of ET- 1, NO, hs-CRP and the amount of ICAM- 1 were (142.61 ±25.67)ng/ml, (66.05 ± 8.63) μmol/L, (2.86±0.40)mg/L, (0.29±0.05) in the normal group; (182.38±22.96)ng/ml, (28.70±4.49)μmol/L, (5.60±0.49)mg/L, (0.58±0.06)in the AS group; (154.37±21.11)ng/ml, (45.88±11.36)μmol/L, (3.66±0.34)mg/L, (0.37±0.04)in the control group and (152.13±23.23)ng/ml, (57.67±8.96)μmol/L, (3.70±0.40)mg/L, (0.36±0.04) in the therapy group respectively. The levels of ET-1, NO, hs-CRP and the amount of ICAM-1 have significant difference between the AS group and the normal group(P=2.47E-4, 6.02E-19, 1.11E-12, 2.51E-18). There was also significant difference between the control group and the AS group(P=0.005, 1.59E-14, 1.87E-5, 3.87E-14). The level of NO in the therapy group was higher than that in the control group (P=0.002). The levels of ET-1, hs-CRP and the amount of ICAM-1 did not have significant difference between the therapy group and the control group(P=0.81, 0.81, 0.48) Conclusion Guizhi Fuling Capsule has effects of Anti-atherosclerosis on rats with AS.

Objective To observe the effect ofprostaglandin E1 intravenously in the improvement of the function of renal glomeruli and renal tubules in hypertensive patients complicated with microalbuminuria.Methods Totally 60 hypertensive patients complicated with microalbuminuria and nocturia who had received losartan for above 12 weeks,according to random number table method were divided into treatment group and control group,with 30 cases in each group.Original antihypertensive drugs were used continuously in treatment group and control group,and patients in treatment group received prostaglandin E1 intravenously for 3 courses of treatment,with losartan and other antihypertensive drugs routinely.Using self-contrast before and after treatment and contrast with control group,the change of urinary level of microalbumin (mALB),osmotic pressure,β2-microglodulin (β 2-MG) and N-acetyl-β-D-glucosaminidase (NAG) were compared.Results The blood pressure after treatment in both groups were decreased,but there was no statistically significant difference compared with that before treatment (P ＞ 0.05).After treatment of 12 weeks,urinary levels of mALB,β 2-MG and NAG in treatment group were lower than those in control group [(88.6 ± 14.2)μg/min vs.(123.9 ± 14.8) μg/min,(0.84 ±0.41) mg/L vs.(1.61 ±0.49) mg/L,(30.2 ± 10.5) U/L vs.(75.7 ± 12.8) U/L],and osmotic pressure was higher than that in control group [(591 ± 71) mmol/L vs.(454 ± 67) mmol/L],the difference had statistical significance (P ＜ 0.01).Conclusion Prostaglandin E1can reduce the renal ischemic state in early stage of hypertensive renal damage and can improve renal function.

Objective To study antioxidation functions effect of Guizhi-Fuling Capsule in rats with atherosclerosis(AS). Methods 50 healthy SD male rats were randomly divided into 2 groups: normal group(n=12), and AS model group (n=36). The model of experimental AS rats was established by high cholesterol diet and intraperitoneal injecting Vit D3. The normal control group was fed by ordinary diet. AS model group was randomly divided into 3 groups: AS group (n= 12), control group (n= 12), therapy group (n=12). Therapy group was given Guizhi-Fuling Capsule (0.24 g/kg · d-1) , control group was given simvastafin (0.86 mg/kg · d-1 ) and captopril(4.3 mg/kg · d-1)by intragastric administration for four weeks. Oxidized-low density lipoprotein (oxLDL),malondialdehyde (MDA), superoxide dismutase(SOD) in serum were detected at the end of therapy. Results Compared with the normal group The oxLDL [ (83.46 ± 19.42)pg/dl], MDA [ (7.38 ±2.46)nmol/ml] in serum were increased significantly(both P＜0.01 ), while SOD[ (135.70±23.49)nu/ml] was decreased significantly (P＜0.01 )in AS model group. Compared with the model group, the oxLDL[(45.87± 1l.91)pg/di], MDA[ (5.27 ±1.95)nmol/ml] in serum in control group ,the oxLDL[(26.73±9.06)pg/dl], MDA[(4.05±1.83)nmol/ml] in serum in therapy group were lower significandy (all P＜0.01 ), and the lowering effect in therapy group was better than that in control group. SOD in serum was higher significantly in the two treatment groups [in control group (185.87±37.36)nu/ml (P＜0.01)、 in therapy group (158.65±31.4S) nu/ml (P＜0.05) ], and the increasing effect in therapy group was better than that in control group. ConclusionGuizhi-Fuling Capsule has the effects of resisting atherosclerosis to rats with AS. Its mechanisms maybe relate to its antioxidation functions.

BACKGROUND: Living-donor kidney transplantation is not only associated to prognosis of recipients, but also donors' healthy. Complete medical and psychological assessment should be performed prior to transplantation to ensure the safety of donors. OBJECTIVE: To analyze and summarize the assessment experience of living-relative kidney donors prior to transplantation. METHODS: Totally 77 cases of living-relative kidney donors admitted at Organ Transplantation Center, Second Affiliated Hospital of General Hospital of Chinese PLA between January 2006 and March 2008 were reviewed. Among them, the analysis was carried out respectively according to the live donor nephrectomy guide of the United Kingdom (2005 Edition) before January 20, 2008, and live donor kidney transplantation consensus Boao meeting after January 20, 2008. In common practice, hypertension, diabetes mellitus, cardiovascular system, infectious disease study, age, obesity, proteinuria, renal artery, renal function, receptor for HLA typing and medical ethics, were systematically evaluated. RESULTS AND CONCLUSION: Of the 77 cases of assessed patients, 69 were qualified, successful donors, and completely cured, without complications. Totally 8 cases of non-donors were due to: 2 cases for hypertension combined with end organ damage; 2 for diabetes mellitus; 1 confirmed malignant tumor in kidney-donated surgery; 1 in the activity period of hepatitis B; 1 for resistance from his wife with medical ethics. The average age of donors was 45.3 years old, including and 7 cases above 60 years old, 24 of 50-59 years old, 29 of 30-49 years old, and 9 below 30 years old. There were 39 cases of parent child donation, 1 child parent donation, 19 siblings donation, 7 cases of three generations of collateral serum, and 3 cases of donation between husband and wife. Of successful donors, blood pressure was above 140/90 in 8 cases; Successful donors were without symptoms of myocardial ischemia but 14 cases had consciously ECG ST-T changes; 3 cases had abnormal fasting blood glucose. The successful donors' body mass index (BMI) reached the average of 23.05 kg/m~2, were below 30 kg/m~2; In assessment of infectious diseases, 3 cases were hepatitis B HBs and HBc-positive in a non-activity period, and the antibody titers were below 500 IU/L. In renography, glomerular filtration rate (GFR) was assessed to average (137.3±28.5) mL/min, and no significant statistical difference emerged (P < 0.05). Vascular three-dimensional CT prompted many left renal artery root in 3 cases, accounting for 4% in successful donors, 1 case did not match, accounting for 1%. It demonstrated that the primary purpose of assessment of -living-donor renal transplantation is to ensure that the adaptability, safety and health of donors. In order to avoid the omission of important medical information and unnecessary invasive inspection, as well as reducing the fees of medical assessment, the assessment should be based on the familiar, universally recognized, clinical evidence-based and reasonable procedures and the flexible assessment process.

Objective To explore the anatomical morphology of femoral trochlear groove and the difference between normal males and females.Methods Eighty healthy volunteers were recruited,including 42 males and 38 females with an average age of 36.2 years (range,21-55 years).All the volunteers without knee unstabilization,pain and wound.CT scan of right femurs were performed and 3-D model were reconstructed.The anatomical parameters of right femoral trochlear groove were measured,which included transepicondylar axis,medial and lateral length of trochlear groove,medial and lateral condylar height,sulcus angle,depth of trochlear groove,transcondylar axis,anterior femoral condylar angle,trochlear groove position,and then compared the morphologic difference of trochlear groove between males and females.Results The average width of transepicondylar axis was 79.21±3.80 mm for males and 70.73±2.91 mm for females (t=-53.40,P=0.00).The minimum sulcus angle was acquired at 45° flexion for males and 42° flexion for females.It was 133.92°±4.76° for males and 132.71°±4.36° for females.The maximum length of transepicondylar axis was acquired at 87° flexion for males and 90° flexion for females.It was 42.36±3.48 mm for males and 39.03 ±3.36 mm for females.The anterior femoral condylar angle decreased with the increasing flexion angle of knee (P＞0.05).The position of the trochlear groove moved laterally with the increasing flexion angle of knee (P＞0.05).Conclusion There is no significant difference between male and female in the geometry of femoral trochlear groove,however there is a significant difference in sizes.Therefore,during design the knee prosthesis,close approximation of size is essential,while gender differences in morphology need not be considered a factor.
