The cytokine-receptor- heparin sulfate functional complex combined by cytokines, cytokine receptors, and heparin sulfate chains formed by concatenation of heparin sulfate proteoglycans (HSPG), an important component of extracellular matrix and modified by some relative enzymes, can regulate the density of cytokine receptors and their intracellular signal transduction. This article focused on the regulatory function of this complex. Many morphological abnormalities and diseases occur when the complex is dysfunctional.

In recent years, along with the in-depth research of Y-STRs, a lot of new loci are found and applied in forensic medicines. To solve some questions, the International Society of Forensic Genetics have published two guidance and recommendations successively concerning the Y-STRs in 2001 and 2005, which clarify contents regarding the term, the nomenclature principle of loci and alleles and the population genetics et al of Y-STRs. This report mainly describes the nomenclature principle of loci and alleles of Y-STRs.

Objective To explore the possibility for preventing the underwater blast injuries. Methods Fifty rabbits were divided into two groups: protection and control groups. The animals were placed at the rang of 5.0m to 17.5m far from the explosion point. 0.2kg of TNT Explosives was placed 3 meters under water. Physical parameters of blast wave were measured using pressure transducers. At 6 hours after injury, the mortality rate and morphological alternations were observed. Results The safe devices were shown to be effective against underwater blast injuries. Most of the animals had no or mild pulmonary and intestinal injuries. The whole injury severity was reduced by 2 to 3 degrees with our own made device. Conclusion Our safe device could be used to protect against underwater blast injueirs.

Objective To investigate the pathogenic constitution of thyroid nodular diasease and it' s di-agnosis and treatment.Methods A retrospective analysis was performed on data of 576 patients accepted hospi-tal therapy with thyroid nodular diasease from January 2004 to June 2008.Results Definite diagnosis of all easeswere made by surgery biopsy or fine needle aspiration-cytology.529 eases were benign lesions, another 47 eases were malignant lesions.Condusions Ultra-sound , FNAC and frozen sections have important value in differenti-al diagnosis for the thyroid nodules, nodular goiter is most common, and which have a close relationship with thy-roid carcinoma.Regular surgical resection would reduce the recurrence of thyroid nodular diasease and avoid missed diagnosis for thyroid carcinoma.

Objective To summarize the experience of how to preserve parathyroid glands and their function in thyroidectomy. Methods Data of 872 patients with thyroid carcinoma who entered our hospital from May. 2006 to Oct. 2009 were retrospectively analyzed. Results Parathyroid damage rate was 2. 06% (18/872)and permanent hypoparathyroidism was 0. 23% (2/872). All occurred in total thyroidectomy. Conclusions Preserving blood supply for parathyroid and avoiding direct contusion or misresection are important for preventing hypoparathyroidism in thyroidectomy. Calcium supplementation should be given to patients with obviously low serum calcium level after surgery to prevent permanent hypoparathroidism.

Objective To discuss the operative technical details in reducing complications after thyroid diseases reoperation, especially how to choose operative method and preserve laryngeal recurrent nerve and parathyroid gland. Methods The study protocols of 183 patients undergoing reoperation for thyroid disease from Jan. 2000 to Mar. 2009 were reviewed. There were 115 cases of benign and 68 cases of malignant thyroid diseases to observe the postoperative complications. Results The rates of temporary and permanent laryngeal recurrent nerve injury were 4.92% (9/183) and 1.64% (3/183), respectively. The rates of temporary and permanent hypocalcemia were 4.37% (8/183) and 0.55% (1/183), respectively. The rate of postoperative internal hemorrhage was 0.55%(1/183). Conclusions The thyroid reoperation was more difficult and can seduced a high rate surgical complication. The thyroid reoperation can be successfully performed if the operators could pay attention to the operative skill.
