Objective:To investigate the clinical efficacy of different doses of atorvastatin in the treatment of chronic heart failure.Methods:A total of 100 patients with chronic heart failure who received treatment in the Third People's Hospital of Bengbu Medical College from June 2019 to June 2020 were included in this study. They were randomly divided into a control group (conventional treatment + atorvastatin calcium tablet 10 mg, n = 49) and an observation group (conventional treatment + atorvastatin calcium tablet 20 mg, n = 51). Before and after 12 weeks of treatment, serum levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) and inflammatory cytokines such as high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), interleukin-10 (IL-10) as well as ventricular remodeling (echocardiographic index) were compared between the two groups. Results:After treatment, serum level of NT-proBNP was (506.56 ± 62.37) pg/mL and (660.85 ± 74.55) pg/mL, serum level of hs-CRP was (14.74 ± 2.69) mg/L and (23.31 ± 3.45) mg/L, serum level of IL-6 was (36.77 ± 4.78) ng/L and (43.12 ± 5.22) ng/L, serum level of IL-10 was (12.36 ± 2.63) ng /L and (15.39 ± 3.56) ng/L, left ventricular end diastolic diameter was (37.74 ± 6.83) mm and (42.36 ± 7.73) mm, left ventricular ejection fraction was (45.78 ± 3.31)% and (42.63 ± 2.56)%, and the ratio of early (E wave) to late (A wave) diastolic velocities (E/A) was (1.44 ± 0.06) and (1.21 ± 0.03), respectively in the observation and control groups. There were significant differences in serum levels of NT-proBNP, hs-CRP, IL-6 and IL-10 as well as LVEDD and LVEF between the observation and control groups ( t = 3.73, 3.07, 3.58, 3.68, 2.99, 3.12 and 2.98, all P < 0.05). Conclusion:Atorvastatin is beneficial to the prognosis of patients with chronic heart failure. The therapeutic efficacy of 20 mg atorvastatin per day is better than that of 10 mg atorvastatin per day.

Objective To investigate a special optimization technique for computer aided measure, and provide anatomical basis for screw internal fixation in the cavitas glenoidalis through the coracoid process of scapula. Methods Thirty accurate scapula models were reconstructed from CT data sets. First, special optimization objective function was designed for single screw internal fixation configuration, and the optimal placement of screw was found automatically under constraints. Then, the placements of double screws internal fixation configuration were searched taking advantage of principal component analysis. Finally, statistical measure data were provided according to new anatomical reference landmarks for clinical use. Results For single screw internal fixation configuration, the distance from the optimal screw entry point P to the acromion process point X was (39.15±2.28) mm, to the coracoid process point Y was (28.66±2.68) mm, to the angulus superior point Z was (61.13±6.57) mm;The angle was (81.27±7.15)° between PX and PY, and (133.27±6.84)° between PX and PZ. The mean inclination of the lag screw was (104.08±4.41)° for the angle with line PX, (101.29±3.51)° with line PY, and (76.23±5.03)° with line PZ. For double screws configuration, the distance from the original single screw entry point P to the screw entry point E was (5.12±1.37)mm,to the screw entry point F was (3.88±0.94)mm. The angle between the long axis of coracoid process and line EF was (27.41±3.51)°. Conclusion The automatic optimization technique for computer aided measure is very efficient and has many advantages over the conventional manual dissection methods, and is convenient to design new anatomical reference landmark system for clinical use.

Retroperitoneal laparoscopic live donor nephrectomy offers an intrinsic advantage over conventional transperitoneal laparoscopic nephrectomy because of the potentially lower risk for early and late donor intraperitoneal complications. Herein we presented our experience performing retroperitoneal laparoscopic live donor nephrectomy in 105 donors. All donor nephrectomy was successful. There were no donor deaths and no conversion to open surgery. Mean operation time was 112 min (range, 70-200 min). Intraoperative blood loss was 10-150 mL with an average of 30 mL. Warm ischemia time was 1.3 to 6 min with an average of 3.1 min. Postoperative retroperitoneal hematoma occurred in only one case and there were no other surgical complications. Donors were discharged from the hospital 5 to 10 days postoperation. Average postoperative hospital stay was 6.4 days. One graft was removed due to acute rejection. Delayed graft function occurred in two recipients but renal function returned to normal within four weeks. The other recipients had normal renal function in two weeks except three recipients in four weeks. We believe that retroperitoneal laparoscopic live donor nephrectomy is safe, reliable, and less invasive.

Two fragments G1 and G2 of the glycoprotein G gene of bovine respiratory syncytial virus(BRSV) were selected for expression in Escherichia coli based on the analysis of glycoprotein G by DNA Star software.Then the two fragments of glycoprotein G were amplified by PCR with synthesized G gene of BRSV as the template.The amplified fragments G1 and G2 are 570bp and 308bp in length,respectively.The PCR products were cloned into pET30a vector and expressed in soluble form in E.coli after induction of cultured E.coli with IPTG.Both of the recombinant proteins G1 and G2 were purified by immobilized Ni ion affinity chromatography under native conditions.Then the purified proteins were analysed by Western blotting.The results showed that the purified recombinant protein G1 retained good antigenicity and specificity.But the purified recombinant protein G2 didn't possess biological activity.Antibodies against BRSV were detected in suspected bovine serum samples in China by using indirect ELISA and Western blotting with the purified recombinant protein G1.The purified recombinant protein G1 might be used as antigen for establishing serological methods for diagnosis of BRSV infection.And the purified recombinant protein G1 might also be used for preparing polyclonal and monoclonal antibodies for research on biological functions of glycoprotein G of BRSV.
