Objective To compare therapeutic effect of Losartan and hydrochlorothiazed compound prepara- tion and Losartan in patients with mild to moderate hypertension and to conduct economical evaluation. Methods The trial began with 2 weeks lead-in period and followed by 8 weeks therapy. 99 cases of mild to moderate hyperten- sion were randomly divided into two groups: compound preparation group ( n = 50) and Losartan (n = 49). The pa- tients were given Losartan 50 mg/h ydrochlorothiazed 12.5 mg compound preparation and Losartan 50 mg ,once a day. If the SeDBP≥85 mm Hg at 4th week, Losartan was added to 50 rag. Results After two, four and eight weeks treatment, systolic blood pressure and diastolic decreased obviously (P < 0.01 for each) ;The overall effective rate of of antihypertension was the same in both groups, but the different ratio of availability and validity in two groups was significant ( P < 0.05 for each). Conclusion Losartan/hydrochlorothiazed compound preparation has significant advantage in improving both systolic and diastolic pressure compared with monotherapy of Losartan. In ad- dition, the patients receiving compound preparation are well tolerated, with higher compliance.

Objective:To analyze the clinical features of 63 azoospermic patients with microdeletion of azoospermia factor C region(AZFc) and their relationship with sex hormones.Methods:The clinical data of 63 azoospermic patients with AZFc microdeletion were retrospectively analyzed, including age, height, body weight, body mass index(BMI), testicular volume, and sex hormones.Results:Compared with normozoospermic men, height, body weight, and testicular volume revealed statistical differences in azoospermic patients with AZFc microdeletion( P<0.05). There were significant differences in FSH, LH, testosterone(T), and prolactin levels between two groups( P<0.05). BMI was negatively associated with FSH level( r=-0.251, P=0.04)and positively associated with estradiol(E 2)level( r=0.327, P=0.009). Age had a negative association with T level( r=-0.256, P=0.04). Testicular volume revealed a negative association with FSH level( r=-0.289, P=0.02). There were no association of height with T, E 2, FSH, and LH levels( P>0.05). Conclusion:It is more likely that azoospermic patients with AZFc microdeletion present overweight and earlier decreased androgen level. The adjustment of lifestyle and testosterone supplementation might be beneficial to the long-term quality of life in these patients.

Objective To investigate CT features of subconjunctival fat prolapse and choristoma. Methods Thirty-eight patients, including 18 with subconjunctival fat prolapse and 20 with choristoma, were retrospectively analyzed. Transverse plain CT scan was performed in all the patients, and then coronal plane images was reconstructed at CT workstation. Results CT features of subconjunctival fat prolapse revealed a crescent-shaped or horn-shaped fat density mass continuous with the orbital fat in the superior temporal quadrant of the orbit. CT features of choristoma revealed a crescent-shaped or triangle fat density mass incontinuous with the orbital fat in the temporal side. Conclusion Subconjunctival fat prolapse typically occurs in bilateral superior temporal quadrant of the orbit in elderly males. Subconjunctival choristoma occurs in the unilateral temporal side in adolescent. CT is helpful to distinguish subconjunctival fat prolapse and choristoma.

Objective To investigate the role of fluid therapy in treatment of septic shock in children.Methods A total of 48 pediatric patients with septic shock were enrolled.Twenty-seven patients were treated with volume expansion and 21 patients were treated with fluid resuscitation.There were no differences in use of antibiotics,inotropic and vasoactive agent in two groups.The time needed for haemodynamic stability,occurrence of pulmonary edema.length of PICU stay,and mortality were compared between two groups.Results Compared with volume expansion group,the time needed for haemodynamic stability significantly decreased in fluid resuscitation group ((216.10± 168.13) minutes vs (121.63 ± 75.59) minutes) (P < 0.05). There were no significant difference in occurrence of pulmonary edema between volume expansion group and fluid resuscitation group (14.8% vs 9.5% . P > 0.05) .Compared with volume expansion group,length of PICU stay significantly decreased in fluid resuscitation group ((6.188 ±3.250) days vs (3.944±2.711) days,P < 0.05).Compared with volume expansion group,mortality significantly decreased in fluid resuscitation group (40.7% vs 14.3%,P < 0.05) . Conclusions Rapid fluid resuscitation was associated with early reach of haemodynamic stability,short stay in PICU,improved survival rate and no increase in the risk of complication in pediatric patient with septic shock.

Photoacoustic imaging is a kind of non-invasive technology without ionizing radiation that can be used to image optical absorbers in tumor tissues according to the principle of "light in and sound out". It has the advantages of high contrast of optical imaging as well as high penetrability of acoustic imaging. However, current researches on photoacoustic imaging are still limited in the laboratory. This technology can be used for detection of cutaneous melanoma in situ and non-melanoma skin cancer, sentinel lymph node imaging, detection and eradication of circulating tumor cells by combining real-time laser ablation technique, and versatile imaging and treatment with the aid of exogenous imaging agents. This review summarizes preclinical experiments about photoacoustic imaging technology in skin tumors, with a view to promoting its clinical application at an early date.
