Thyroglobulin antibody (TGA) production in vitro by cultured peripheral blood mononuclear cells (PBMC) from patients with autoimmune thyroid disease (AITD) was measured by ELISA technique. PBMC from patients with AITD could synthesize and secret detectable amount of TGA. The average positive rate of TGA production in vitro was 31.25%. PBMC from the patients with Hashimoto thyroiditis (HT) could produce TGA more easily than that from the patients with Graves'disease (GD). The average positive rate was 44.19% in HT and 16.22% in GD. Pokeweed mitogen could increase TGA production, but soluable thyroglobulin could not stimulate TGA synthesis and secretion. Antithyroid drug methi-mazole had some inhibition effect on TGA production in vitro. A significant positive correlation between the serum TGA and the amount of TGA produced in vitro by PBMC from HT patients (r = 0.4, P

The annual incidence of prostate cancer (PCa) continually increases. New PCa immune therapy has become the fourth line antitumor treatment following surgery, radiotherapy and chemotherapy. As the most promising research direction in cancer immunotherapy,immune checkpoint inhibitors, such as programmed cell death-1 and programmed cell death-ligand 1 (PD-1/PD-L1) inhibitors, block PD-1 and its ligand PD-L1 and then terminate the negative control signal to the T cell, thereby facilitating T cell recovery and reversal of tumor immune-escaping mechanism. These processes restore the capability of T cells for immune response and inhibit and kill tumor cells. This review summarizes the progress on the current application of PD-1/PD-L1 inhibitors in PCa clinical trials.

Lithium(Li) salt is. a kind of effective drug commonly used in the treatment and prevention of mental disorders, but its active mechanism is still not well understood. Getting on for twenty years, many research have been reported on relationship between Li salt and second messenger system, especially the effect of Li salt on adenylate cyclase. Identical result is not obtained and there are few reports on brain calmodulin (CaM) activity change by Li salt. The aim of present expcri- ment is to determine the content of CaM in raet brain by phosphodiesterase (PED) method after chronic application of Li salt and discuss preliminary the molecular mechanism of Li salt action. The result showed that marked change has happened in the content of CaM in rat brain after chronic application of Li salt. It is ins-plied that Li salt brings its action into play probably by changing the content of CaM in rat brain

Nipple-areola complex (NAC)-sparing mastectomies (NSM) have gained acceptance in the ifeld of breast oncology. The superior aesthetic outcomes of NSM explain their increased use and rising popularity. Technical considerations and challenges of this procedure are centered on nipple ischemia and necrosis. Patient selection, reconstructive strategies and incision placement have lowered ischemic complication rates. An understanding of the NAC vascular anatomy is, therefore, clinically relevant beyond NSM. In this paper, the relevant clinical anatomy is described, mainly focusing on the anatomy of the NAC. This article also covers how to identify and classify the in vivo blood supply to the NAC using breast MRI exams which provide valuable information for assessing vascular anatomy of the NAC. This includes the arterial iflling phase, venous drainage phase and 3-dimensional reconstructed maximum intensity projection (MIP) images. Finally, the indocyanine green (ICG) and a specialized infrared camera-computer system provide surgeons with a practical tool to assess real-time breast skin and NAC perfusion. Intraoperative evaluation of skin perfusion allows surgeons to detect ischemia and modify the operative approach to reduce the risk of nipple ischemia and necrosis.

Objective To explore the etiologies, clinic symptoms and the methods of emergency therapy for neonatal convulsion. Methods Eighty-four patients with convulsion in pediatric department in our hospital were reviewed,analysed and summarized their clinic informations,first-aid measures. Results The etiologies were HIE(hypoxia-ischemic encephalopathy)41 cases(48.8%),ICH(intracranial hemorrhage)16 cases(19.0%),and hypocalcemia 9 cases(10.7%),the quantity of these patients added up to 2/3 of all. Conclusion The primary measures to reducing incidence of the diease were as follows:do well health protection during perinatal period,treat betimes aiming at etiologies,prevent fleetly paroxysm of convulsion.

Vascular cognitive impairment (VCI) is a cognitive impairment caused by cerebrovascular disease and its risk factors,its mechanism is very complex Recent studies have shown that cerebral microbleed (CMB) is correlated with VCI.This article reviews the relationship between CMB and VCI.
