Objective To study the effects of combined telmisartan and ramiprll on heart function and renin - angiotensin - aldoste-tone system and ventricle remodeling and brain natriuretie peptide in patients with chronic heart failure (CHF). Methods 100 patientswith chronic heart failure were randomly divided into three groups: telmisartan group (A group, treated with telmisartan 80mg once daily, n =33), ramipril group (B group treated with ramipril 5mg once daily, n =33) and telmisartan plus ramipril group (treated with telmis-artan 40mg plus ramipril 2.5mg once daily, n = 34). Left ventricular end - diastolic dimensions (LVEDD) and left ventricular ejection fraction (LVEF) were assessed, and plasma renin activity (Ren) , angiotensinIl (Angll), aldosterone (Aid) and brain natriuretic pep-tide (BNP) were measured before and after therphy. Results After 6 months of treatment, LVEDD and LVEF were improved in all groups(P < 0.01). All changs were significant in C group than those in A group or B group(P < 0.01). The concentration of Ren were in-creased in all groups(P <0.01). The concentration of Angll was increased in A group and decreased in B group(P <0.01)while there was no difference at pre or post treatment in C group (P > 0.01). The concentration of Ald and BNP was decreased in all groups (P < 0.01). Ald and BNP were decreased more significantly in C group than those in A group or B group. Conclusion Combination of low dose of telmisartan and ramipril therapy has more benificial clinical features than telmisartan or ramipril alone in patients with CHF.

The common, particular structure and the arrangement pattern of the retinula in the compound eye of the housefly Musca domestica have been investigated, and the structures of the retinula cells here been compared with an electron microscope under dark, bright and high intensity light adaptation condition.In general, the retinula of the compound eye is composed of eight retinula cells, but some retinula is composed of six, seven, or nine, ten retinula cells.The arrangement pattern of the retinula in the right, left compound eye and dorsal, ventral regions of the compound eye are the mirror image inversion. But the arrangement pattern of some retinula in the dorsal or ventral region is also the mirror image inversion.The greater part of pigment granules in the retinula cells No.1～6 move towards the rhabdomere, the pigment granules in the retinula cells No.7～8 do not move, but the pigment granules in the some retinula cells No.7～8 move towards the rhabdomere under high intensity light adaptation condition.

1. The central retinular cells R_7 in the compound eye of male housefly can be divided into two types which are called here R_(7a) and R_(7b) respectively. R_(7a) approximate many features of R_(1-6) cells, which have a larger, cell body, rhabdomere and axon, terminate in the first optic neuropil (lamina). R_(7b) approximate many features of R_8 cell and project directly to the second optic neuropil (medulla). 2. The central retinular cell R_(7a) in the compound eye of male housefly distribute mainly the dorsal region of the eye, there are a few of R_(7a) in the ventral region of the eye, which only distribute in the first and second row ommatidia under equatorial line, but not found in the compound eye of female housefly.

Objective　To investigate radiographic features of pneumocystis carinii pneumonia(PCP)or Kaposi sarcoma(KS),which were the most common complications of AIDS after renal transplantation.Methods　Radiographic diagnosis and differential diagnosis of 2 cases with PCP and KS comfirmed by pathology were discussed by analysing the chest X-ray findings combined with revieuw of reference literature.Results　The two cases with anti-HIV antibody all had mediasinal lymphopathy.In the case of KS,the omental tuber or tubercle shadows and pleural effusion were found on both pulmonary fields.Conclusion　No characteristic chest radiographic meanifestations in AIDS,the definitive diagnosis depends on clinical laboratory examination and pathological examination.

AIM To explore the roles of vascular endothelial growth factor (VEGF) in hypoxia pulmonary hypertension and effects of suramin. METHODS Thirty SD rats were randomly divided into normal control group (N), hypoxia hypercapnia group(F), hypoxia hypercapnia +suramin group (S). The levels of VEGF in serum and in lung tissue were measured by ELISA, the ultrastructure of pulmonary arterioles was observed by electron microscopy, the expression of VEGF was observed by immunohistochemistry, the expression of VEGFmRNA was observed by in situ hybirdization. RESULTS ①Mean pulmonary arterial pressure(mPAP), weight ratio of RV to LV+S, the leves of VEGF in serum and in lung tissue of group F were significantly higher than that of group N and group S (P

Micro-and ultrastructure of the photoreceptors and first visual ganglion in the different regions of the compound eye of the wild male and female housefly, and the projections of the photoreceptor cells within the subsequent visual centers have been studied. The morphology of the retina and lamina ganglia in the front dorsal and the equatorial regions of the male compound eye and the front ventral region of the female one, and the projections of the retina within the lamina show the sexspecific characteristics underlying the function of chasing behavior in the housefly.

The changes of the ultrastructure of the photoreceptors in the compound eye of horsefly (Tabanus mandarinus) were observed electromicroscopically at both the mid-day and mid-night. We found that there were various structural changes in cones, pigment cells, retinula cells, rhabdomeres at the two different times.The functional significance of the day and night changes of the photoreceptors and their relations to natural light illumination were discussed.

Objective To provide data evidence for early diagnosis of bone and joint damage derived from brucellosis by analyzing its clinical and imaging characteristics.Methods Patients with brucellosis accepted in Ji'nan Infectious Disease Hospital form December 2013 to December 2014 were selected.Patients with bone and joint damage confirmed through imaging were further studied,their epidemiological and clinical characters,CT and MRI characteristics,treatment and outcome were summarized.Results Total of 97.8％ (45/46) patients had a clear contact history,most of them worked in poultry farming,taking up to 67.4％ (31/46).July to October was its peak time for attacking,taking up to 58.7％ (27/46).The clinical manifestations of patients were joint pain,swelling and activities obstacles.In the CT images,there was obvious bony destruction,characterized by multiple round or large areas of low density insect damage sample spots.There was osteosclerotic bone lesions or osteophyte formatted in edge.The paravertebral soft tissue was swelling,and the vertebral body deformation was not obvious,and there was vertebra small joint damage occasionally.In the MRI images,there was vertebral ligaments damage,or soft tissue damage,or osteoproliferation at the edge of the vertebral bodies.There was abnormal signal T1W1 or T2W1 signal,and FS-T1W1 showed high signal,while FS-T2W1 showed slightly high signal.The diagnosis rate of CT,MRI and CT combined MRI for bone and joint damage derived from brucellosis was 76.1％ (35/46),84.8％ (39/46) and 91.3％ (42/46),respectively.The main therapeutic drugs were doxycycline and rifampicin,and the clinical effective rate was 91.3％ (42/46).Conclusion The epidemiological characters,CT and MRI characteristics of bone and joint damage derived from brucellosis have certain representativeness,and the comprehensive investigation is beneficial for clinical diagnosis.
