age reconstruction. Results showed spillage of the contrast agent from the anterior wall of the ascending aorta, approximately 4.5 cm from the replaced aortic valve. A histological examination confirmed that the site of contrast agent spillage was the sutured area of the ascending aorta, which was infected, necrotic, and had ruptured. Using the CTA approach for isolated cardiopulmonary organ imaging can accurately display the location of an aortic rupture, which further guides organ inspection and tissue sampling, and avoids irreversible damage to key regions. In conclusion, the approach we describe can provide evidence for determining cause of death.
Herpes simplex virus (HSV) is a disease usually characterized by lesions within the epidermis or mucosa of children and adults. However, this infection can also cause complications to many systems of the body, including the peripheral and central nervous system, respiratory system, and hepatobiliary system. In this case, we present a 43-year-old man with a history of substance abuse, who presented with fever, cough, and headache, and within days, progressed into fulminant hepatitis and hypoxic failure. Bacterial and fungal cultures were negative, as well as the workup for human immunodeficiency virus. However, the presence of HSV was detected in a bronchial lavage culture after the patients had expired. This result, along with the findings at autopsy, including viral cytopathic effect in the lung and liver, which were confirmed with immunohistochemical stains for HSV, strongly suggest that the cause of death is from disseminated herpes virus infection with hepatitis and viral pneumonitis. This disseminated isseminated herpes virus infection with hepatitis and viral pneumonitis. This disseminated infection occurred in an immunocompetent host without any evidence of mucocutaneous lesions.
We report 3 individuals with clostridial sepsis, 2 culture-confirmed and 1 assumed based on historical information and autopsy findings. Case 1 a 46-year-old man with history of colon cancer status postcolectomy was found unresponsive and rapidly developed decompositional changes. At autopsy, within 1 day of his death, he had marked gaseous distention of the scrotum and palpable crepitance from the eyes to the feet, with bullae formation in the suprapubic region and left thigh. Postmortem culture of bullae fluid grew Clostridium septicum. Case 2 a 63-year-old woman with history of non-Hodgkin's lymphoma who was identified to have Clostridium perfringens by hospital cultures. Autopsy was performed the day after death. The skin had a generalized red-tan discoloration. PCO371 The liver had large gas pockets in the parenchyma. Microscopic examination revealed bacterial rods. Other than diverticulosis and mild coronary artery atherosclerosis, no other disease process was identified. Case 3 a 34-year-old man was found dbable clostridial sepsis.
The aim of the study was to investigate whether the skeletal age can be evaluated assessed by means of analysis of ossification stage at proximal humeral epiphysis using magnetic resonance imaging (MRI).
This retrospective study was carried out in the radiology department of a tertiary healthcare center and 1.5-T MRI views of the shoulder obtained from 203 patients aged 8 to 29 years were evaluated. The ossification stage of proximal humeral epiphysis was evaluated on T1-weighted MRI sequences, and its correlation with age was sought.
Our series consisted of 77 women (37.9%) and 126 men (62.1%). One hundred forty-seven right humerus (72.4%) and 56 (27.6%) left humerus were examined. The mean age of the patients was 20.60 ± 4.41 years. The patients were in stages 4 (n = 148, 72.9%), 3c (n = 18, 8.9%), 3b (n = 14, 6.9%), 2c (n = 13, 6.4%), and 3a (n = 10, 4.9%). Analysis of the relationship between age and ossification stage of proximal humerus epiphysis indicated that stage increased with the advancement of age. There was a significant correlation between the stage and age variables at a rate of 77% in the positive direction (P < 0.001).
Our results demonstrated that MRI of proximal humeral epiphysis can have valuable implications for estimation of the skeletal age. Future prospective studies must be implemented with patients grouped according to socioeconomic status, nutritional habits, and physical activities to explore the actual investigative potential of MRI.

Surgical intervention can improve the semen quality of some of the patients and significantly increase the pregnancy rate, but fails to benefit them all. Therefore, it is of great practical significance to identify the patients who can significantly benefit from surgical interventions to maximize the effectiveness of surgery and avoid medical waste. This article summarizes the recent progress in surgical indications and strategies for varicocele in adult males, and provides some reference for the management of the disease.In order to maintain the stability of intracellular environment, various cells die autonomously in vivo, which is called apoptosis. As a key factor of cell apoptosis in the mitochondrial pathway, cytochrome c, somatic (CYCS) plays an important role in the process of male spermatogenesis. Based on more than 40 recent studies on CYCS by Chinese and foreign scholars, this review focuses on the involvement of CYCS in the mechanisms of the apoptosis and anti-apoptosis of germ cells and in the regulation of their quality and activity and also outlines the role of CYCS in marking male reproductive performance as well as in male infertility and its underlying mechanisms.
To investigate the effects of Xiongcan Yishen Prescription (XYP) on the expressions of cholesterol transport proteins, steroidogenic enzymes and steroidogenic factor-1 (SF-1) in the Leydig cells of the rats with late-onset hypogonadism (LOH).
Twenty-five 18-month-old male SD rats were randomly divided into five groups of equal number, LOH model control, testosterone propionate (TP) and low-, medium- and high-dose XYP, and another 5 two-month-old male SD rats included as normal controls. After modeling, the animals in the TP group were treated by intramuscular injection of TP at 5.21 mg/kg qd alt, those in the low-, medium- and high-dose XYP groups intragastrically with XYP at 10.4, 20.8 and 41.6 g/kg qd alt respectively, and those in the LOH model and normal control groups with saline, all for 28 successive days. Then, all the rats were sacrificed for determination of the expressions of the cholesterol transport proteins StAR and TSPO, steroidogenic enzymes CYP11A1, HSD3B7 and HSD17B4, and SF-1 in the Leydig cells by Western blot.
