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

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

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.

Bone Marrow Mesenchymal Stem Cells (BMSCs) are ideal seed cells for cell therapy,which have been through many long-term studies of in vitro and animal disease model treatment and have been widely used in preventing and treating a variety of clinical diseases caused by aging and other damage,including bone injury and regeneration,neural degenerative and injury,myocardial injury,liver cirrhosis,diabetes,lung disease and so on.BMSCs application in the treatment of orthopaedic disease is the most common and effective.By retrospective literature review,we summarize the BMSCs transplantation application in Orthopaedic disease treatment.As an ideal cell source,BMSCs was first applied in bone tissue engineering,mainly used in the treatment of long bone defect and bone nonunion;Recently,the research trends of clinical BMSCs application turned to treat degenerative diseases and genetic disorders because of its great potential,including osteoarthrits,femoral head necrosis,disc degeneration,spinal cord injury,knee varus,osteogenesis hypoplasia,hypophosphatasia and so on.The safety and efficacy of BMSCs treatment are the key issues in clinical cell therapy.There is no side effects and complications after BMSCs treatment,prove its clinical application is safe.But due to type and degree of disease and individual differences,therapeutic methods including injection method,effective concentrations,treatment window selection,cycle and therapeatic effects have a bigger difference.There is still no uniform of recognized operation standards for the treatment of the same type of disease.So BMSCs transplantation requires effective control during whole medical process and its application in orthopedic diseases is still lack of large-scale multicenter clinical study.Therefore,this review focuses on induction,summary and analysis in the research status of BMSCs in bone disease treatment,and provide new ideas and methods for BMSCs transplantation in orthopaedic disease prevention and treatment.

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 understand the death level and main death causes among residents in the Wansheng Economic De‐velopment Zone to provide the basis for comprehensive prevention and control .Methods According to the ICD‐10 international classification of diseases ,the death causes were classified and coded for statistically analyzing the crude mortality rate ,standardized mortality rate and the death causes constituents in this surveyed population .Results The crude mortality rate of residents in Wan‐sheng Economic Development Zone during 2014 was 650 .57/100 000 and the standardized mortality rate was 413 .35/100 000 .The sequence of death causes was circulatory system disease ,respiratory system disease ,tumor ,injury and poisoning and digestive sys‐tem diseases .The death number for these 5 kinds of death causes accounted for 93 .21% of the total death number .The top five of potential life loss years were injury and poisoning ,tumor ,circulatory system disease ,respiratory system disease and digestive system diseases .The rates of potential years of life loss were 13 .76‰ ,10 .19‰ ,8 .35‰ ,4 .84‰ and 2 .69‰ respectively .Conclusion Chronic noncommunicable diseases ,injury and poisoning become the main causes of death in the Wansheng Economic Development Zone and disease burden .

Thirty New Zealand albino rabbits of both sexes were used for the experi-ments which was (1) To observe the febrile response induced by microinjection of TNFinto the lateral ventricle; (2) To measure the PGE_2 & cAMP contents of the plasma andcerebrospinal fluid. The results showed that injection of TNF (50ng/each) into the lateralventricle did induce a definite raise of body temperature (T=0.79?0.14℃). The PGE_2concentration increased markedly in c. s. f. while that in plasma remain unchanged ascompared with the control. However cAMP lever in both, plasma and c. s. f. had nochange. These results suggested that (1) The injection of TNF into the lateral ventriclecaused a raise in PGE_2 synthesis in the brain while there was no alterations of PGE_2found in peripheral blood (2) The increase in PGE_2 didn't followed by an increase incAMP which indicated that the fever induced by TNF must have a different mechanismfrom that induced by leucocyte pyrogent (LP or In-1). PGE_2 might be involved in thefever inducing mechanism but these results don't support the hypothersis that the raiseof PGE_2 level may increase the cAMP content which in turn reduced the fever.

Objective To explore the relationship between the changes in activity of caspase-8 and apoptosis of HepG2 cells induced by 5-fluorouracil(5-Fu). MethodsThe HepG2 cells were treated with 5-Fu. The caspase-8 activity was detected using caspase-8 Fluorescent Assay Kit. The apoptotic rates of HepG2 cells induced by 5-Fu with or without the caspase-8 inhibitor IETD-FMK were measured by flow cytometry. ResultsAfter treatment with 10 -2mol/L 5-Fu, the caspase-8 activity in HepG2 cells increased gradually and reached the peak at 16 h. With the concentration of 5-Fu increasing, the caspase-8 activity also elevated, the group of high concentration was significantly higher than that of low concentration(P
