The breakage of component is rare in TKA and usually restricted to hinges and linked design. Occasionally fracture of metal tibial component has been noted, but fracture of the femoral component has been rarely reported and occurred to be a significaot problem in TKA. This study reports 2 cases of femoral component fracture using Whiteside Ortholoc total knee system and analyzes the cause of this phenomenon. One pahent, a 67 years old female who weighed 74kg, was performed 1ke left TKA using Whiteside Ortholoc g system with cement. The size of feraoral component was small plus, and small tibial component, 14mm tibial insert and 28mm pateBa were used, The medial site of femoeal component fractured at 38 months postoperatively. A second female patient, who weighed 68kg and was 64 years old at the time of surgery, had also the left TKA using a medium sized femoral component of Whiteside Ortholoc modular system with cement. The small-Ex large tibial component, 8rrun tibial insert were used, but did not replace the pateBa. Also at 37 mainths postaperatively the medial site of femoral compcnent fractured, Ail cases were revised with using a cemented P,F.C. Modular Total Knee System (Johnson k Johnson). All two cases were kactured at the junction between the posterior bevel md distal surface of the medial femoral condyle. The thickness and length of Whiteside Ortholoc femoral component are thinner and shorter at posterior bevel surface compared with other TKA systems. So it is encouraging that a minor design modification of Whiteside Ortholoe femoral component and also should be edueated for the prohibihon of excessive flexion of the knee joint after TKA.

Aneurysms of the pulmonary artery are uncommon in general but have a potentially fatal prognosis. This is derived from the potential for rupture of the aneurysm from the fact that there is commonly underlying severe pulmonary hypertension. Most cases are documented in the large postmortem series. Aneurysms of the pulmonary artery can be classified as congenital or acquired. Possible symptoms include dyspnea on exertion, cough, hemoptysis, and thoracic pain. When a large aneurysm formation of the pulmonary artery is diagnosed, surgical intervention is indicated because conservative treatment of the aneurysm will undoubtedly result in rupture with fatal outcome. We report a case of 46-year old patient with a giant left pulmonary artery aneurysm associated with severe pulmonary hypertension. A Doppler echocardiogram and a computed tomographic scan showed a giant saccular aneurysm of the left pulmonary artery (12 cm in diameter) and estimated systolic right ventricular pressure of 80 mmHg.

Ischemic heart disease is a common complication of thyrotoxicosis, although the exact mechanism has not been defined. In patient with dextrocardia as a part of situs inversus, coronary heart disease may occur with similar frequency and manifestation as in the general population. A case is reported of angina and thyrotoxicosis in patient with situs inversus totalis in which the angina was manifested by ST-segment elevation during graded exercise, relieved by antithyroid treatment. This unusual case establishes an association between hyperthy-roidism and ischemic heart disease.

OBJECTIVETo investigate the correlations of 24 biochemical markers in the seminal plasma with routine semen parameters.

METHODSAccording to the WHO5 standards, we analyzed the routine semen parameters of 66 subfertile men, including the semen volume, sperm concentration, total sperm count, sperm motility, and the percentage of progressively motile sperm (PR). Based on the calibration and quality control measures and using an automatic biochemistry analyzer or electrolyte analyzer, we detected 24 biochemical markers in the seminal plasma of the patients, including total protein (TP), albumin (Alb), globulin (Glb), uric acid (UA), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AKP), γ-glutamyltransferase (GGT), lactate dehydrogenase (LDH), creatine kinase (CK), alpha hydroxybutyrate dehydrogenase (αHBDH), adenosine deaminase (ADA), glucose (Glu), triglyeride (TG), total cholesterol (TC), urea nitrogen (UN), creatinine (Cr), high-sensitive C-reactive protein (hsCRP), K+, Na+, Cl- , Ca, Mg, and phosphorus (P). Then we analyzed the correlations of the 24 biochemical markers with routine semen parameters.

RESULTSThe levels of the TP, Alb, and Glb proteins in the seminal plasma were positively correlated with sperm concentration, so was that of Alb with the total sperm count, and the AST and LDH activities with sperm concentration and total sperm count. The AKP activity in the seminal plasma was correlated negatively with the semen volume, but positively with sperm motility. The αHBDH activity exhibited a positive correlation with both sperm concentration and total sperm count, with a coefficient of correlation (r) above 0.7. The UN level was correlated negatively with the semen volume, so was the Cr level with the semen volume, sperm concentration, and total sperm count, and the Glu level with sperm concentration and total sperm count. The TG level was correlated positively with the semen volume, but negatively with sperm motility. The levels of seminal plasma ALT, GGT, ADA, UA, TC, CK, and hsCRP showed no correlation with the above-mentioned semen parameters. None of the seminal plasma K+, Na+, Ca, Mg, and P levels was found correlated with semen parameters except the Cl- level, which was negatively correlated with the semen volume.

CONCLUSIONMany biochemical markers in the seminal plasma are closely related to routine semen parameters, indicating that these biochemical components may play roles in spermatogenesis, sperm maturation, and physiological metabolism.
