Objective: To study left ventricular diastolic function (LVDF) in patients with coronary artery disease(CAD) by tissue Doppler imaging (TDI) and color Doppler echocardiography. Methods: The maximum velocity ( V max ) and time velocity integration(TVI) in early and late diastolic stage of mitral valve orifice of 80 patients with CAD and 79 normal subjects were measured by color Doppler echocardiography at apical 4 chamber view. Meanwhile, the V max and/or TVI of the myocardial motion spectrum of left ventricular lateral wall near the mitral valve annulet were measured by TDI. These data were compared and analysed by statistical method. Results: In the normal subjects, the older the subject, the lower the V max and TVI of early diastolic stage, the higher the V max and TVI of late diastolic stage. In CAD group, changes were not associated with ages and were affected by the degree of the myocardial pathology. The LVDF couldn't be exactly judged by color Doppler echocardiography when pseudonormalization blood flow spectrum appeared, but TDI technique was relatively sensitive. Any regional myocardial motion could be measured by TDI according to the examiner's design. Conclusion: LVDF by color Doppler echocardiography is simple and convenient. TDI technique can be used for determining overall LVDF and left ventricular systolic function. [

Objective To analyze the incidence of urinary stone formation in the contralateral kidney of unilateral nephrectomy patients.Methods 1048 patients,including 596 males and 452 females,underwent unilateral nephrectomy from June 2010 to June 2016.Their age ranged from 16-87 years old (mean 58.7 years old).532 patients combined with components of metabolic syndrome and 213 patients with metabolic syndrome.164 patients had a previous history of urolithiasis.The incidence of urinary stone formation in the contralateral kidney after nephrectomy was recorded and analyzed.The urolithiasis incidences in different gender,age,comorbidity and history of urolithiasis patients after uninephrectomy were compared.Results All patients were followed up within 0.5 to 6 years (mean 3.2 years).89 patients suffered from urinary stones in the contralateral kidney after uninephrectomy.The incidence of urinary stone formation in the contralateral kidney was 8.5% (89/1048),which was higher than that in general population of China.1%-5%.The urolithiasis incidence was 9.1% (54/596)in male patients and 7.7% (35/452)in female patients after nephrectomy.The incidence of urinary stone formation was 8.6% (3/35)in patients aged under 30 years old,12.5% (34/272) in patients aged 30-49 years old,7.3% (37/504) in patients aged 50-69 years old,6.3% (15/237)in patients aged 70 and over.The incidence of urinary stone formation was 12.2% (65/532) in patients with components of metabolic syndrome after nephrectomy and 19.7% (42/213) in patients with metabolic syndrome,while the incidence was 4.7% (24/516)in patients without components of metabolic syndrome.In patients with history of urolithiasis,the incidence was up to 30.5% (50/164) after nephrectomy,while 4.4% (39/884)in patients without history of urolithiasis.Conclusions The incidence of urinary stone formation in the contralateral kidney of uninephrectomy patients was higher,especially in patients with metabolic syndrome or urolithiasis history.Patients after unilateral nephrectomy are more vulnerable to urolithiasis.

To evaluate the feasibility and safety of suprapubic three-arm robot-assisted laparoscopic radical prostatectomy (STA-RLRP). Fifteen patients with prostatic cancer underwent STA-RLRP. All the 15 procedures were completed successfully, without the need for ancillary trocars or additional instruments. No patient required conversion to standard laparoscopy or open surgery. STA-RLRP is feasible and safe with good short-term tumor control, satisfactory recovery of urinary control function and good cosmetic outcome, which is worthy of clinical application.

OBJECTIVE To analyze the pharmaceutical service process in a fracture patient complicated by fat embolism syndrome (FES) following postoperative fracture, aiming to provide a reference for clinical treatment and pharmaceutical service for similar patients. METHODS Clinical pharmacist participated in the entire treatment process of a patient with FES following postoperative fracture. Based on the patient’s clinical manifestations and test results, literature was reviewed to assist clinical physicians in formulating the therapeutic regimen of glucocorticoids. For the drug-related adverse reactions of renal function impairment and reduced platelet count that occurred during the treatment, suspicious drugs were analyzed and disposed of accordingly. RESULTS The clinical pharmacist recommended Hydrocortisone sodium succinate for injection (100 mg, q8 h, ivgtt, for about one week followed by a gradual dose reduction) for treating FES. The Vancomycin hydrochloride for injection used in this case was assessed as “very probably” associated with the adverse drug reactions of renal function impairment and thrombocytopenia. The clinical physician adopted the pharmacist’s medication recommendations, and the patient’s condition stabilized after treatment, with improvement in adverse reactions, and was discharged from the hospital. CONCLUSIONS The use of glucocorticoids in treating FES has a definite therapeutic efficacy. Clinical pharmacists should individualize the medication plan based on the patient’s pathological state and distinguish it from postoperative sepsis. Meanwhile, drug-induced adverse reactions in the kidney and blood system should be closely monitored.

Objective:
To investigate the deposition rate of Artemisia pollen in different nasal cavity regions and its influence factors in residents of northwest China.
Methods:
Thirty healthy adults from northwest China were enrolled. The computational fluid dynamics (CFD) and discrete phase model (DPM) were used for numerical simulation of nasal structures. The pollen deposition fraction in each anatomical part was counted and the effects of pollen density and breathing rate on deposition were analyzed. SPSS 19.0 software was used for statistical analysis.
Results:
The hottest deposition parts of Artemisia pollen were nasal septum (30.70%±12.27%), vestibule (27.45%±8.21%), middle turbinate area (13.59%±8.98%) and nasopharynx (7.14%±5.90%). When the inspiratory flow rate increased to 30 L/min, the deposition rates of pollen in nasal vestibule and nasal septum were significantly higher than that at the rate of 15 L/min (43.20%±11.14%
