Objective To observe the efifcacy of rosuvastatin in patients with unstable angina and its impact on the levels of lipids, high sensitive C-reactive protein (hs-CRP), homocysteine(Hcy) and troponin I (cTnI). Method 384 patients with unstable angina, from January 2010 to December 2012, were randomly divided into observation group and control group, each group had 192 cases, the control group received simvastatin, the observation group were gave rosuvastatin. The efficacy, and the levels of lipids, hs-CRP, Hcy and cTnI were observed after treatment. Results The total effective rate was 92.19%in observation group which was signiifcantly better than 81.25%in control group (χ2=9.044, P<0.01). Before treatment, the levels of TG , TC, LDL-C, HDL-C, Hcy, hs-CRP and cTnI showed no signiifcant difference, after treatment the levels of TG , TC and LDL-C, Hcy, hs-CRP and cTnI were signiifcantly lower than those before treatment (P<0.01), while, the levels of HDL-C signiifcantly increased than those before treatment (P<0.01), the reducing or increasing levels in observation group were more signiifcant compared with the control group (P<0.01). Conclusion Rosuvastatin treatment in unstable angina not only can reduce plasma lipid, but also reduce their inflammation, and stabilize the arterial plaque for unstable angina, it play an important role in development and prognosis.

To compare two enrichment and preservation methods of urinary proteins, stored in polyvinylidene difluoride (PVDF) membrane (Urimem) or direct freezing, we examined the differences between the two methods in time, space, costs of supplies and electricity, degree of protein degradation and convenience of the sample handling. The urimem method is superior in the storage space, the cost of electricity and the clinical convenience compared to the direct freezing method. However, the direct freezing method is superior in the time and the cost of supplies to the urimem method. The enrichment and preservation of urinary proteins using urimem have more cost-effective benefits compared to those of the direct freezing method.

Objective:To explore the differences in intravascular ultrasound results in elderly coronary heart disease(CHD)patients with different uric acid levels.Methods:A total of 145 elderly patients diagnosed with CHD in our hospital from December 2017 to May 2020 were included as study subjects.Uric acid levels were measured and intravascular ultrasound examination was conducted in all patients.They were divided into different groups based on uric acid levels: Group A(uric acid≤199 μmol/L), Group B(uric acid 200~399 μmol/L)and Group C(uric acid≥400 μmol/L). Data from intravascular ultrasound-derived indexes were analyzed and compared between the three groups.Results:There was no significant difference in the degree of left main stenosis between Group A and Group B, but it was less severe in both groups than in Group C( F=5.625, P=0.039). Plaque fibrous cap thickness showed no significant difference between Group B and Group C, but it was smaller than in Group A( F=7.825, P=0.020). Group C had the largest plaque area and maximum thickness among the three groups, followed by Group B[(11.12±1.73)mm 2 and(1.76±0.24)mm]and Group A[(8.29±3.14)mm 2 and(1.38±0.09)mm]( F=6.384 and 6.827, P=0.028 and 0.015). Conclusions:Elevated uric acid levels in elderly CHD patients can increase the area and thickness of plaques, and reduce plaque fibrous cap thickness, leading to an increased risk of formation of unstable plaques, which can be life-threatening for these patients.Thus, monitoring and managing uric acid levels should be stressed in elderly CHD patients.

Objective To investigate the clinical features of pneumocystis pneumonia (PCP) in patients with chronic kidney disease. Methods Clinial data of 21 cases of the primary and secondary kidney diseases complicated with PCP,excluding renal transplantation,were analyzed retrospectively. Results Twenty-one cases consisted of 6 cases of primary renal diseases and 15 eases of secondary renal diseases.Twenty patients (95.2%) were receiving immunesuppressive therapy at the PCP onset.Main manifestations were fever,progressive dyspnea,cough with no or seldom sputum.Twenty patients presented obvious hypoxemia and 12 of them were type I respiratory failure.X-ray and CT imaging of 20 patients revealed diffuse pulmonary interstitial shadows or ground glass opacities in both lungs.All the patients were treaed with trimethoprim-sulfamethoxazole.Eleven patients died accounting for 52.3%.Compared with the survivors,elder age (60.91±15.08 vs 44.50±14.83,P<0.05),lower blood oxygen pressure at onset [(48.11±19.05)mm Hg vs (65.91±13.13)mm Hg,P<0.01],higher percentage of respirator application and other secondary lung infection were found in dead patients.No PCP relapsed after average 16-month follow-up in the survival patients. Conclusions PCP is a severe complication with high mortality during immunosuppressive therapy in patients with chronic renal disease.Early diagnosis and proper treatment are important to improve prognosis.
