The second part of (2008 edition)includes iodine deficiency disease,thyroditis and thyroid nodule.This guideline reaffirms the epidemic characteristics,the prevention and the management of iodine deficiency disease.It identifies the measurement of iodine nutritional status and the necessity of iodinized salt.It emphasizes the regular diagnosis and treatment of subacute and chronic thyroiditis,and also mentions the advancement on differential diagnosis and rational therapy of thyroid nodules.In addition,it gives some advices on the management of thyroid nodules in two special groups(pregnant women and children).

Pacinian corpuscles from cat mesentery were fixed in Carnoy's fixative, paraffinsectioned and stained in Feulgen reagent and methyl green-pyronin. Controlled sectionswere hydrolyzed in 20% perchloric acid at 70℃ and 10% perchloric acid at 1-4℃. Itwas found that the so-called nuclei in the lamellae were Feulgen positive and stainedbluish purple after the methyl green-pyronin method. They disappeared after perchloric acidhydrolysis in 70℃ and showed no change after cold treatment. Their histochemicalreactions, stainability and detailed structures were similar to the nuclei of the connectivecells next to the corpuscle. It was therefore concluded the nuclear like bodies in the Paciniancorpuscles studied were true nuclei as mentioned in histological textbooks and not merely thecondensation of fibrils as W. Schwarz recently claimed after electron microscopic observation.These nuclei were located in between the fibrils of the lamellae.

Objective:To design a simulative model for the forecast and optimal placement of mass casualty evacuation assets.Methods: An operation research module named the location selection problem was introduced in this study.The probabilistic location set covering problem was chosen as the theoretical model for optimal placement of mass casualty evacuation assets.Several indeterminate factors were analyzed in details,including the availability;capacity and velocity and effective work time of evacuation assets.The ideal statistical distributions were determined by the characteristics of these variables.Results: According to the principle of Monte Carlo simulation and based on the probabilistic location set covering problem,random numbers fitting theoretical probabilistic distributions were generated to simulate those indeterminate factors,based on which a simulative model for optimal placement of casualty evacuation assets was designed.Conclusion: This simulative model may be used as a basis for further development of a computer-assisted program and as a reference for medical administration commanders at different levels.

Glaucoma is one of the main causes of blindness in the world,resulting from a slow and progressive loss of retinal ganglion cells (RGCs) and their axons.So far,intraocular pressure reduction is the main treatment modality to control disease progression.However,not all the patients benefit from this therapy,and the pathophysiology of glaucoma is not always associated with an elevated intraocular pressure.These limitations,together with the multifactorial etiology of glaucoma,urge the pressing medical need for novel and alternative treatment strategies.Such new therapies should focus on not only preventing or retarding RGCs death,but also repairing the injured axons.Glaucoma optic nerve protection therapy is becoming a hot spot of current research,especially Rho associated kinase (ROCK) inhibitors as a new drug for the glaucomatic neuroprotection,which can reduce intraocular pressure,inhibit scar formation after anti-glaucoma surgery,improve blood circulation,prevent RGCs death and axonal degeneration and induce axon regeneration.In this review,we focused on the research status and progress of the classical signal pathway of ROCK inhibitor in glaucoma optic nerve protection.

Objective To observe changes of red blood cell distribution width (RDW) and trace albumin urine (MAU) in patients with chronic heart failure (CHF) and to explore the relationship between them and cardiac function classification. Methods A total of 190 patients with CHF were divided into mild group (NYHA grade II), moderate group (NYHA gradeⅢ) and severe group (NYHA gradeⅣ), according to the grade of cardiac function. A total of 100 subjects with normal physi?cal examination during the same period were selected as the control group. The changes of MAU, urinary creatinine (Scr) ra?tio (UACR), RDW, Scr, hemoglobin (Hb), type B urine sodium titanium (BNP) and left ventricular ejection fraction (LVEF)were compared between four groups. The correlation between UACR, RDW, Scr, Hb, BNP and LVEF were analyzed. Re?sults The levels of RDW, Scr, BNP, hypersensitive C-reactive protein (hsCRP), LVEDd, LVM, LVMI and UACR were sig?nificantly higher in chronic heart failure group than those of control, showing a trend of increase gradually with the rising of heart function classification (P<0.05). The values of Hb and LVEF showed a gradually decreasing trend with the increased heart function classification (P < 0.05). The values of UACR and RDW showed a gradually increasing trend with the in?creased heart function classification (P<0.05). There was a positive correlation between UACR and RDW, and both had a positive correlation with BNP, and a negative correlation with LVEF and Hb(P<0.05). Conclusion RDW and MAU are re?lated to the cardiac function classification, and both can be used for the evaluation of the prognosis in patients with CHF.

The prevalence of osteoporosis has increased during recent years. The activation in the function of osteo?clast is the main reason of osteoporosis. Cathepsin is expressed by osteoclast and involved in the degradation of collagen of bone,and causes osteoporosis. Cathepsin K is a kind of most important enzyme in the family of cathepsin. Odanacatib(ODN) is the inhibitor of cathepsin K, and it may be used to anti-osteoporosis thought inhibiting the degradation of bone collagen. It was found that the cortical thickness and bone minerals of cancellous increased after taking ODN in the studies, and then the density and the strength of bone increased. This study reviewed the pharmacological profile of ODN and the progresses of ani?mal study and clinical trials about ODN.

Objective To evaluate the performance of enzyme linked immunosorbent assay(ELISA)reagent kit of hepatitis B surface antigen(HBsAg)with Clinical and Laboratory Standards Institute(CLSI)document EP12-A2,and to compare two different manufacturer kits′performance.Methods According to CLSI document EP12-A2,to evaluate the performance of two different manufacturers′HBsAg ELISA kits.Results The positive rates both were ≥95% by using the kits of two manufacturers to detect the same sample with 120%of the critical concentration.The negative rates were both ≥95%by using the kits of two manufactur-ers to detect the same sample with 80% of the critical concentration.The intra assay coefficients of variation were ≤15%,and the interassay coefficients of variation were ≤20%.The sensitivities of two manufacturers′kits were respectively 94.2%(95%CI:84.3%-98.0%)and 92.3%(95%CI:81.8%-97.0%),and the specificities were 98.0%(95%CI:89.5%-99.6%)and 100.0%(95%CI:92.8%-100.0%).The 95%interval of sensitivity of two manufacturers′s kits was 5.46%-10.19%,and which of specificity of two manufacturers′s kits was -2.00%-5.32%.Conclusion The kits of two manufacturers can provide stable re-sults of HBsAg detection with concentrations ±20% outside the critical concentrations at the cutoff point with high sensitivity and specificity.Both of the kits have no significant differences in sensitivity and specificity.
