Objective To explore the efficacy and safety of recombinant human brain natriuretic peptide (rhBNP) in the patients with severe heart failure (HF). Methods A prospective multicenter study was conducted. Patients whose age > 18 years old, and with the New York Heart Association (NYHA) cardiac function grade overⅢ - Ⅳ , acute cardiac insufficiency and the acute exacerbation of chronic cardiac insufficiency admitted to intensive care unit/cardiovascular care unit (ICU/CCU) of 58 Hospitals in China were enrolled. On the basis of the conventional treatment, all patients would be given rhBNP (neo adjuvant) with a loading dose of 1.5 μg/kg for 3-5 minutes, and followed by a maintenance dose of 0.010-0.015 μg·kg-1·min-1 for 3-7 days. Before the treatment and 1, 3, 7 days after treatment, researchers detected indexes of cardiac and renal function, the levels of N-terminal B-type natriuretic peptide (NT-proBNP), left ventricular ejection fraction (LVEF), cardiac output (CO), pulmonary capillary wedge pressure (PCWP), central venous pressure (CVP), urea nitrogen (BUN), serum creatinine (SCr), and urine output; the renal function index was re-evaluated at 30 days after administration, and the time entering ICU again, re-admission, cardiovascular events were recorded. Results 408 patients were enrolled, with 241 males and 167 females. Age range was 28-95 years, the average age was (63.0±15.8) years, and 50-70 years old accounted for 46.8%. Compared with the data before treatment, NT-proBNP, PCWP and CVP significantly decreased at 6 hours after treatment [NT-proBNP (μg·kg-1·min-1): 4378.58±4082.29 vs. 6403.41±5759.48, PCWP (mmHg, 1 mmHg = 0.133 kPa):12.41±2.21 vs. 14.26±2.85 , CVP (mmHg): 10.63±2.62 vs. 11.45±3.45, all P < 0.05], and with the prolongation of injection, NT-proBNP, PCWP and CVP were gradually declined; CO 1 day after treatment (mL: 4.89±0.81 vs. 4.40±0.92) and LVEF 3 days after treatment (0.465±0.100 vs. 0.431±0.107) were significantly increased (both P < 0.05), and with the prolongation of injection, CO and LVEF were gradually increased. There were no obvious changes in BUN and SCr during the treatment, but 30 days after treatment, SCr was significantly lower than that pre-treatment (μmol/L: 110.98±47.40 vs. 132.62±75.60, P < 0.01). Compared with the data pre-treatment, urine output per hour was significantly increased at 3 hours after treatment (mL: 129.59±82.16 vs. 89.60±53.49, P =0.000); urine output every 24 hours was significantly increased at day 1 and day 2 after administration (mL: 2676.54± 1006.83, 2678.74±975.97 vs. 2150.36±283.76, both P < 0.01). In 7 days, the re-entry ICU rate was 2.7%, and the re-hospitalization rate was 2.88% within 30 days, re-cardiac failure rate was 1.43% in 30 days, and the overall fatality rate was 9.55% in 30 days. Conclusions The rhBNP can significantly improve heart function in patients with HF. And, it has a certain effect on renal function. The rhBNP is effective and safe for the treatment of cardiac insufficiency.

Objective:Our aim was to investigate the proportion of autosomal recessive (AR) inheritance among families with patients with Duchenne muscular dystrophy (DMD) and clinical feature in patients with AR form of DMD. Methods:A total of 193 families was studied, 8 of them with at least one girl with “DMD - like” phenotype and 185 with only boys with this kind of phenotype. Based on the number of families with at least one affected girl and the number of patients per sibship among these pedigrees, the proportion of families with DMD inherited as an AR trait was estimated. The clinical examination, family history and serum creatine-kinase were studied in 11 patients diagnosed as AR form of DMD. Results: The proportion of families with AR form of DMD was estimated as 9.4%. The average age of being able to walk is (1.47±1.00) year, serum creatine-kinase levels were (2785.10±1500.29) U/L. The clinical symptom occurred at the average age of (8.11±4.32) year in patients with AR form of DMD. Conclusion: The AR form of muscular dystrophy and DMD not be distingushed clinically. Some families with only affected boys diagnosed as typical DMD, in fact, have the AR form of the disease. This study is very useful for genetic consulting.

BACKGROUND:Periprosthetic femoral fracture is a severe complication after total hip arthroplasty. More than 85% belongs to Vancouver B2 and B3 fractures, and the operation is difficult. OBJECTIVE:To explore the clinical effect of Cable-Ready fast system and biotype long-stem prosthesis and its effect on the recovery of joint function in patients with Vancouver B2 and B3 type periprosthetic femoral fractures after total hip arthroplasty. METHODS: A total of 60 patients receiving total hip arthroplasty suffered from Vancouver B2 and B3 type periprosthetic femoral fractures in the Huanggang Central Hospital from September 2011 to September 2012. They were equaly divided into control and observation groups according to different fixation methods. Patients in the control group were treated by ordinary steel wire cerclage fixation combined with uncemented long-stem prosthesis; those in the observation group were treated by Cable-Ready fast system combined with fast uncemented long-stem prosthesis. RESULTS AND CONCLUSION:The average operation time, the time of hospitalization and fracture healing time were shorter in the observation group than in the control group. Moreover, the intraoperative blood loss was less in the observation group than in the control group. After 1 year of folow-up, Harris hip score was higher in the observation group compared with pre-treatment (t=3.174 9,P=0.002 6), and significantly higher than the control group (t=2.479 8,P=0.015 4). The excelent and good rate of Harris hip score was significantly higher in the observation group than in the control group (χ2=11.294 5,P=0.002 6). The total incidence of complications was significantly lower in the observation group than in the control group (χ2=8.139 7,P=0.04 2). These data indicate that Cable-Ready fast system combined with uncemented long-stem prosthesis in the treatment of Vancouver B2 and B3 periprosthetic femoral fractures after total hip arthroplasty has smal injury, less postoperative complications and better recovery of hip function after operation.
