Objective To evaluate the value of iterative modal reconstruction (IMR) for reducing radiation dose and controlling image quality in cardiac CT. Methods Ten pigs were included. All pigs were scanned on a 256?slice prospectively ECG?gated cardiac CT utilizing routine dose (group A) and tube current reduced by 30%(group B), 50%(group C) and 70%(group D), respectively. Filtered back projection (FBP), hybrid iterative reconstruction (iDose4) and IMR were used for all data, respectively. Image noise and contrast?to?noise ratio (CNR) of ascending aortic root were measured, while overall image quality and coronary artery image quality was rated (five point scale). All results reconstructed by FBP, iDose 4 and IMR were compared. Objective measurements were compared with one?way analysis of variance, and subjective assessments were compared with Kruskal?Wallis H test andχ2 test. Results Compared with that of FBP and iDose4, image noise of IMR was(15.1 ± 6.1),(18.8 ± 5.5),(22.1 ± 4.8)and(33.0 ± 4.0)HU, respectively in group A, B, C and D with significant reduction (F=82.77, 90.71, 96.59, 95.51 respectively, all P<0.01). Using IMR, groups A, B, C, D had higher CNR (42.0±11.1, 37.2±10.4, 31.4±8.7, 23.7±7.0;F=50.65, 53.55, 76.60, 57.36, all P<0.01) and overall image quality (5.0 ± 0.0, 4.8 ± 0.4, 4.6 ± 0.5, 4.5 ± 0.5;H=20.96, 15.63, 18.66, 23.56, all P<0.01) than FBP and iDose4. Using IMR, group A (100%, 40/40) and group B (100%, 40/40) had no significant difference (P>0.05) in the diagnosis rates of proximal coronary arteries compared with that using FBP and iDose4, while group C (100%, 40/40) and group D(92%, 37/40) had significantly increased diagnosis rates (χ2=20.05, 45.72, both P<0.01). The diagnosis rates of distal coronary arteries of IMR reconstruction which were 100%(50/50), 98%(49/50), 90%(45/50), 78%(39/50), respectively in groups A, B, C, D had significant increase compared with that of FBP and iDose4 reconstruction (χ2=7.39, 16.75, 34.62, 81.33, all P<0.05). Conclusions IMR can significantly reduce image noise, improve CNR and image quality compared with iDose4. Application of IMR can reduce radiation dose but without compromising image quality.

Objective To assess the status and severity of bone disease in patients with multiple myeloma (MM) by using chest computerized tomography (CT) and the relationship between clinical prognostic parameters and bone disease.Methods All 46 newly diagnosed MM in-patients received both imaging tests of chest CT and plain X ray.An experienced radiologist reviewed all the imaging data.Clinical laboratory parameters,stages of Durie-Salmon (DS) and International Staging System (ISS) were evaluated.Five cytogenetic abnormalities of bone marrow myeloma cells were tested by fluorescence in situ hybridization (FISH).Results The sensitivity of CT and X ray to determine pathological fractures was comparable,the positive rates of which were 41.3％ (19/46) and 30.4％ (14/46) respectively (P =0.29).Nevertheless,the positive rate of osteolytic lesions ascertained by CT was significantly higher than that by X ray (P ＜ 0.001),60.9％ (28/46) vs 13.0％ (6/46) with diameter 5-10 mm and 50.0％ (23/46) vs 10.9％ (5/ 46) with diameter more than 10 mm.Osteolytic lesion numbers found by CT were more than those by X ray [5(0-21) vs0(0-4) lesions with diameter5-10 mm (P＜0.001),2(0-14) vs0(0-2) lesions with diameter more than 10 mm (P ＜ 0.001),respectively].Patients with positive osteolytic lesions had higher percentage of RB1 gene deletion[46.7％ (14/30) vs 18.8％ (3/16),P ＜0.001],D13s319 deletion [43.3％ (13/30) vs 18.8％ (3/16),P ＜0.001] and high risk cytogenetic abnormalities[50.0％ (15/30) vs 25.0％ (4/16),P ＜ 0.001].Conclusions Chest CT is more sensitive than plain X ray in detecting osteolytic myeloma bone disease.Osteolysis determined by CT is relevant to clinical DS stages and risk stratification of cytogenetic abnormalities.

Background Heat shock proteins (HSPs) are highly conserved proteins that are induced in cells when confronted with a wide variety of proteotoxic stresses.HSP27 has a high degree of similarity with α-crystallin protein.The abnormality of HSP27 structure and expression are closely related to the formation of cataracts.Our previous study showed sodium salieylate has the protective effect on H2O2-induced lens damage.Objective This study was to investigate the roles of MAPK signal pathway in sodium salicylate-induced the expression of HSP27 in human lens epithelial cells (LECs) in vitro.Methods Human LECs were incubated in the fresh media containing sodium salicylate at different concentrations (0-55 mmol/L) for different times (1-5 hours) and allowed to be recovered in fresh medium without sodium salicylate for 1-24 hours with or without pretreatment with P38MAPK inhibitor (SB203580), ERK1/2 inhibitor (PD98059) and JNK/SAPK inhibitor ( SP600125). The expressions of P38MAPK, EBK1/2, JNK/SAPK, phosphorylated P38MAPK, phosphorylated ERK1/2, phosphorylated JNK/SAPK and HSP27 were detected by Western blot. HSP27 mRNA was detected by RT-PCR. The expression of HSP27 was also detected by immunohistochemistry. Results There was only weak expression of HSP27 in normal human LECs.After stimulation of 35-55 mmol/L sodium salicylate was removed and human LECs were cultured again for 6 hours,the expression of HSP27 in LECs were significantly increased ( F= 509. 953,P<0. 01). HSP27 was absent expressed in human LECs in 55 mmol/L sodium salicylate stimulation for 1-5 hours groups, but LECs were re-cultured for 3,6 hours after removed the stimulation, the expression of HSP27 was elevated (F = 452. 534, P<0. 01). Activation of P38 M APK occurred after sodium salicylate stimulation 30 minutes and 1 hour ( F = 865.68, P<0. 01). However, ERK 1/2 was expressed after sodium salicylate was eliminated for 1-6 hours ( F = 388.84, P<0. 01). JNK/SAPK was inactived by sodium salicylate. The expression of HSP27 could be down-regulated with the pretreatment of SB203580 and PD98059. Conclusion Sodium salicylatc can induce the expression of HSP27 in human (LECs) . The effects are mediated,at least in part ,through the activation of P38MAPK and ERK1/2 signaling pathway .

OBJECTIVETo review the implementation of mass vaccination of hepatitis B vaccine and its critical role in prevention of hepatitis B virus infection in China.

DATA SOURCESThe data were mainly from PubMed, China Hospital Knowledge Database, and other popular Chinese journals published from 1980 to 2008. The search term was "hepatitis B vaccine".

STUDY SELECTIONOriginal studies conducted in China and critical reviews authored by principal investigators in the field of hepatology in China were selected.

RESULTSChinese investigators started to develop hepatitis B vaccine in late 1970s. The first home-made plasma-derived vaccine became available in 1986, which has been completely replaced by the domestically produced recombinant (yeast or Chinese hamster ovary cell) vaccine since 2001. China health authority recommended vaccinating all infants in 1992. From then on, China has put tremendous efforts in implementation of mass vaccination. The overall coverage of hepatitis B vaccine in infants has increased steadily and reached more than 95.0% in urban and 83.0% - 97.0% in rural areas. The chronic HBV carrier rate in children < 10 years of age decreased from 10.0% before the mass vaccination to 1.0% - 2.0% in 2006, and that in general population decreased from 10.0% to 7.2%; overall, the nationwide mass hepatitis B vaccination has reduced more than 30 million of chronic HBV infections and HBV related severe sequlae.

CONCLUSIONThe Chinese successful experience in control of hepatitis B by mass vaccination offers an example for any unindustrialized country whoever is committed to control this disease.
