Copy number variations in the human genome,one of the causes of complex diseases and genetic diseases,can lead to genomic disorders.As these diseases are difficult to diagnose,it is significantly meaningful to conduct genetic researches and molecular diagnosis.Chromosomal microarray can be used to detect copy number variations on a genome-wide scale.With the advantage of high throughput and resolution,chromosomal microarray is perceived as an important means of identifying copy number variations in genomic disorders.As technology advancements of chromosomal microarray and accumulations of clinical experiences,chromosomal microarray has played a significant role in etiological diagnosis of multiple malformations,mental retardation and autism.

SUMMARY Hyperparathyroidism is the clinical syndrome that results from elevated circulating parathyroid hormones,leading to multiple systems manifestations,and is divided into three kinds: primary, secondary and ternary.This patient’s main chief complaint was intermittent melena for 3 days,with the diagnosis of upper gastrointestinal hemorrhage according to endoscopy. Hypercalcemia, hypophosphatemia and high level of circulating parathyroid hormone and chronic renal failure were also found during hospitalization. Furthermore, MIBI showed a parathyroid adenoma located near the isthmus in the lower part of the left lobe. The patient had undergone nephrectomy because of kidney carcinoma 2 years ago. Primary hyperparathyroidism usually has the common gastrointestinal syndrome , but upper gastrointestinal hemorrhage reported as the chief complaint is rare and we had never seen similar reports before.

At present, the training pattern in the higher-education institutions of traditional Chinese medicine (TCM) is still characterized as a trilogy of basic medical theory courses, clinical medical courses and graduation clinic practice, which results in the slow-cultivation of the TCM talent, and brings into the severe problems of theory being divorced from practice and bad social adaptability in the graduates. Under this situation, it is imperative to reform the traditional training patterns and to advocate innovation in the education. It is suggested that creative teachers, students' creative study and a democratic, harmonious, relaxing and easy study atmosphere are helpful to the cultivation of TCM talents. Therefore, a student-orientating training pattern of classroom-teaching synchronized with the clinic practice, emphasizing clinic practice, and aiming to improve the scientific research ability is advocated in higher-education of TCM. This is expected to provide some thoughts for the development of TCM higher education in the new era.

Objective To study the effects of psychological stress on breast development and abnormal levels of related hormones or their receptors in pregnant rats .Methods Pregnant Wistar rats were randomly divided into control group and ex-perimental group.The experimental group rats were given unpredictable stress stimuli for 15 days, including noise, restraint, re-versal of day and night , swimming in cold water and tail pinch-induced pain.Gross changes of the breast were observed , the di-ameter and height of breast nipple was measured, and breast coefficient was calculated.DNA and RNA levels in the breast tis-sues were determined by optical density measurement.The estrogen (E2), progesterone (P), growth hormone (GH) and prolac-tin (PRL) levels in plasma and breast tissues were determined by radioimmunoassay.Bmax and Kd of estradiol and progesterone receptors were measured by radolig and bindng assay .Morphological changes of the breast tissues were examined by light micros-copy using HE staining.Results Compared with the control group, the nipple diameter and height, breast weight and breast co-efficient were significantly decreased in the experimental group (P<0.05, P<0.01), the levels of DNA, RNA and RNA/DNA ratio in the breast tissue were significantly decreased (P<0.05, P<0.01), the levels of plasma E2, P and GH were significant-ly decreased (P<0.05, P<0.01), the levels of E2 and GH in the breast tissue homogenate were decreased also (P<0.05, P<0.01), the Bmaxs of E2 receptor and P receptor were decreased, but their Kds increased significantly (P<0.05, P<0.01), and the number of lobules and diameter of acini were significantly decreased (P<0.05).Conclusions Psychological stress can lead to breast dysplasia and abnormal levels of estrogen and progesterone and their receptors in pregnant rats .

Pregnant women with subacute thyroiditis (SAT) are rare.One case was reported and the clinical features and management principles of SAT during pregnancy were reviewed.In pregnant women with SAT,the illness is usually not serious.If subclinical or clinical hypothyroidism develops,L-T4 must be given and thyroid function be monitored routinely,and the medication be adjusted carefully to ensure the maternal-fetal safety.

Objective The purpose of this study is to study the clinical and pathological features of neurilemoma .Methods We observed the clinicopathologic features and immunohistochemical staining from eight patients with orbital neurilemoma between 2010.1~2012.12.Results Eight patients with classic neurilemoma were included in the study ,in which there were five males and three females ,aged between 21 and 63,mean age 35.The main symptom of the patients was exophthalmos ,including five cases of right eyes and three left eyes;2 cases of orbital floor and six above orbit ,lasting for one to ten years .The tumor diameter ranged between 1cm and 5 cm,an average of 3 cm,being pale and light yellow color .There were five cases of type Antoni A and one case of type was Antoni B among the six classic type neurilemoma .Two cases of ancient were neurilemoma ,in which one case was the histological structure of the classic type neurilemoma ,but there were more hypertrophy tumor cells , chromatin was coarse block atypia cells .The other one case with cells arranged disorderly ,which was mainly fine striated cells with scattered deeply stained atypia cells ,stromal transparent degeneration ,cystic degeneration .Im-munohistochemistry results showed that S -100(+),vimentin(+),ki67(-).Conclusion Antoni type B and ancient schwannoma are rare ,with complicated histologic characteristics .Combined with clinical features and im-munohistochemistry staining ,it can be diagnosed .

Objective To explore the clinical features of adrenocortical oncocytoma for better understanding. Methods A total of 586 patients with adrenal cortical adenoma were retrospectively analyzed in our hospital from January 1993 to November 2009, in which 18 were diagnosed as adrenal cortical oncocytoma pathologically, with 7 male and 11 female, aged ( 45.5 ± 15.9 ) years, and the disease course of( 13.3 ± 13.1 )months. Results 6 patients suffered from Cushing's syndrome, 2 primary hyperaldosteronism, 1 had clinical features of both Cushing's syndrome and primary hyperaldosteronism, and 9 were nonfunctional. 4 cases were misdiagnosed as pheochromocytoma preoperatively. All 18 patients were diagnosed by B-mode ultrasound and operation ( 13 by laparoscopy, 5 by laparotomy). 11 tumors were located in the left adrenal while 7 in the right, with the average tumor size of 5.6 cm in diameter. Histopathologically, 1 was oncocytic adrenocortical carcinoma, while 17 were adrenocortical oncocytoma, in which 5 were potentially malignant and 12 were benign. 11 patients were followed up for 20.5±20.1 months. 2 patients were dead, and 9 were alive with tumor recurrence in 1 case.ConclusionsAdrenocortical oncocytoma is a pathological diagnosis and the clinical manifestations are various. The tumors are usually large in size, and can easily be found by ultrasound, but may be wrongly diagnosed as pheochromocytoma.Being different from previous reports, the majority of these patients present with endocrine dysfunction. Most of these cases are benign, but malignant potential is obvious. Therefore,follow-up is very important.
