Objective The objective of this article was to compare patients' dose with electrocardiographic gated mA modulation (ECG) and ECG＆CAREDose 4D mode during coronary MSCT angiography.Methods The research was based on phantom experiment and computer simulation to get the mean value of peak skin dose data and effective dose data respectively and to analyze deterministic and stochastic radiation risk.Results The peak skin dose using ECG mode alone and using ECG＆CAREDose 4D mode with the same image noise level was (87.4±0.9) and (45.9 ± 1.2) mGy respectively.Effective dose was 17 and 10 mSy for ECG mode and ECG＆CAREDose 4D mode respectively.Comparing with ECG mode alone, ECG＆CAREDose 4D mode reduced organ dose of gonad, red marrow, lung, stomach, breast and thyroid by 40.0%, 36.7%, 39.3%, 37.7%, 38.8% and 38.9%, respectively. Conclusion Results showed that ECG ＆ CAREDose 4D mode can reduce radiation dose effectively comparing using ECG mode alone, and that ECG ＆ CAREDose 4D mode should be widely applied ehnically with appropriate initial settings.

AIM: To investigate the effects of Tangmoning (TMN) Granule on nerve conduction velocity, red blood cell sorbitol (RBC S) level in diabetic rats and probe the mechanism of prevention and treatment of diabetic peripheral neuropathy. METHODS: The model of diabetic rat was induced by strepotozotocin. The animals were randomly divided into six groups:TMN minimal dose group, TMN mild moderate dose group, TMN maximal dose group, methycobal group, model group and normal control group. All TMN groups were treated with TMN Granule through tube feeding (2.95 g/kg、5.90g/kg、11.80g/kg). Methycobal group was treated with methycobal tablets through tube feeding (0.14mg/kg). The duration of treatment was 3 weeks. The caudal nerve conduction velocity, RBC S content were investigated before and after treatment. RESULTS: It showed that TMN Granule could increase the caudal nerve conduction velocity significantly in the maximal dose group and the mild moderate dose gorup ( P

Background It is well known that sclera remodeling occurs during axial elongation in myopia under the control of growth hormone or its downstream effectors.The role of transforming growth factor-β (TGF-β) in myopia has been determined in previous studies.Bone morphogenetic protein (BMP) is one of members of the TGF-β superfamily,but if it plays an important role in the genesis and development of myopia is not completely clear.Objective This study was to identify the presence of BMPs in normal guinea pigs sclera and investigate the change of BMPs in the sclera in form-deprivation myopia (FDM) of guinea pigs.Methods Thirty young guinea pigs were randomized into normal control group and experimental group using table of random number.FDM models were established by occluding unilateral eyes of guinea pigs with a translucent lens for 14 days in the experimental group,and the fellow eyes served as the controls.Diopter of all eyes was tested by retinoscopy optometry,and ocular axial length was measured by A-sonography before and after modeling.Posterior sclera tissue of the animals was obtained on 14 days,and the relative expression level of BMPs mRNA and protein were assayed by reverse transcription PCR (RT-PCR) and Western blot.The use and care of the animals complied with ARVO Statement.Results On 14 days after occluding of unilateral eyes,the refraction diopter of the experimental group was (-0.48±0.51) D,and that of the fellow eyes was (3.22 ±0.34) D,showing a significant difference between them (t =-12.814,P =0.000).Also,a significant difference in the diopter was seen between the experimental group and normal control group ([-0.48±0.51]D vs.[2.97±0.70]D,t =-11.878,P=0.000).Axial length was (8.30 ± 0.05) mm in the experimental group,(8.11 ±0.06) mm in the fellow eyes and (8.06±0.06) mm in the normal control group,showing a significant increase in the experimental group compared with the fellow eyes and normal control group (t =7.230,P =0.000 ; t =9.084,P=0.000).The expressions of BMP-2 mRNA,BMP-4 mRNA,BMP-5 mRNA in posterior sclera were detected in the normal guinea pigs.Fourteen days after the induction of myopia,the relative levels of BMP-2 mRNA and BMP-5 mRNA in sclera were 0.41 ± 0.11 and 0.65 ± 0.06 in the experimental eyes,which were significantly lower than 0.62 ± 0.07 and 0.84 ± 0.03 in the fellow eyes with the descent range of 34.48％ and 23.67％ respectively (t=2.838,P=0.017; t=2.524,P=0.028).The relative values of BMP-2 protein and BMP-5 protein were 0.44±0.06 and 0.70±0.05 in the experimental eyes,and those of the fellow eyes were 0.61±0.05 and 0.82±0.03,showing significant decline in the experimental eyes with the lowing range of 23.42％ and 15.21％,respectively (t =2.465,P =0.030;t =2.445,P=0.031).No significant differences were found in the expression of BMP-4 mRNA and protein in posterior sclera between the experimental eyes and the normal control eyes (mRNA:t =0.704,P=0.460;protein:t=0.987,P=0.365).Conclusions The expressions of the BMP-2 and BMP-5 in sclera down-regulate significantly in FDM eyes,which suggest that BMP-2 and BMP-5 participate in sclera remodeling during myopia induction.

Objective To study the significance of the cerebrospinal fluid(CSF)lactate level in diagnosing neonatal bacterial meningitis(BM). Methods The CSF samples were collected from neonates admitted to Neonatal Ward of Children's Hospital of Fudan University between January 2014 and March 2015. CSF lactate and glucose con-centrations were measured with blood - gas analyzer. CSF and serum glucose levels were measured with glucometer. The enrolled neonates were divided into 2 groups based on CSF culture,CSF white blood cells(WBCs)and clinical presenta-tion:observation group(neonates with BM)and control group(neonates without BM). Statistical analysis of data was performed with Stata 12. 0. Results A total of 93 infants(16 assigned to observation group and 77 assigned to control group)met the inclusion criteria. Neonates in observation group had higher median CSF lactate level(4. 2 mmol/ L)and CSF lactate/ glucose ratio(L/ Gcsf)(2. 32 mmol/ L),than those in control group(1. 3 mmol/ L,0. 52),and there were significant differences(Z = - 6. 19,- 5. 92,all P ﹤ 0. 05). CSF glucose levels were lower in observation group(me-dian,1. 25 mmol/ L)than those in control group(median,2. 5 mmol/ L),and the difference was significant(Z = 4. 97, P ﹤ 0. 05);CSF/ serum glucose ratio(CSF/ Sglu)were lower in observation group(median,0. 44 vs 0. 81 in control group),and the difference was significant(Z = 4. 43,P ﹤ 0. 05). The optimal CSF lactate cutoff point of 2. 2 mmol/ L had a positive predictive value(PPV)of 72. 7% and negative predictive value(NPV)of 100. 0% for bacterial meningi-tis. The optimal L/ Gcsf cutoff point of 1. 24 had a PPV of 94. 1% and NPV of 100. 0% . The optimal CSF glucose cutoff point of 2. 0 mmol/ L had a PPV of 65. 0% and NPV of 95. 9% . The optimal CSF/ Sglu cutoff point of 0. 6 had a PPV of 60. 0% and a NPV of 96. 9% . Conclusion CSF lactate may be an excellent biomarker for early diagnosis of neo-natal BM.

AIM: To investigate the early changes of retinal function in diabetic patients detected by multifocal electroretinogram (mfERG).METHODS: The first-order kernel responses of mfERG were recorded from eyes of 33 normal control subjects,63 diabetic patients without retinopathy and 43 diabetic patients with background retinopathy. The response densities and implicit times of N1 and P1 were compared among the control, diabetic patients without retinopathy and diabetic patients with retinopathy.RESULTS: The response densities of N1 and P1 in central 3 rings were reduced significantly in diabetic eyes with and without retinopathy. And the implicit times of N1 and P1 were delayed significantly only in diabetic eyes with retinopathy.CONCLUSION: mfERG can detect the early changes of retinal function quantitatively in diabetic patients. Analysis of response densities and implicit times of N1 and P1 can reflect the progress of local retinal dysfunction in diabetes.

ObjectiveTo find out if the immune system derived thyroid stimulating hormone(TSH) β splice variant(TSHβ-Ⅴ) would be regulated by circulating thyroid hormone levels to get a further understanding of the function and mechanism of this TSHβ-Ⅴ in thyroid homeostasis.MethodsA total of 20 weaning Balb/c mice (half male and half female) were selected and randomly divided into two groups according to their body mass and gender(n =10).Mice of control group were fed with common diet and deionized water.Mice of the low-iodine(LI) group were fed with low-iodine diet(containing iodine 20 - 40 μg/kg,iodine-intake about 0.25 μg/d) and deionized water.The experimental period was 3 months.At the end of the experiment,mice were executed and the blood was collected to observe the levels of TSH and thyroid hormone by chemiluminescence immunoassay (CIA) ; bone marrow (BM),peripheral blood(PBL),thyroid gland and pituitary were collected to assay the TSHβ-Ⅴ mRNA expression by real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR).ResultsThe serum free thyroxine(FT4) and total thyroxine(TT4) levels in LI group of mice[(0.47 ± 0.70)nmol/L,(2.41 ± 0.28)pmol/L] were significantly lower than that of the control group of mice [(55.2 ± 3.68) nmol/L, (32.72 ± 1.02) pmol/L,t =43.81,86.04 、all P ＜ 0.01 ] and the serum total triiodothyronine(TT3) and free triiodothyronine(FT3) reduction in LI group of mice[ (0.76 ± 0.08)nmol/L,(4.01 ± 0.40)pmol/L] were significantly lower than that of the control group of mice [ (1.10 ± 0.06)nmol/L,(5.40 ± 0.38)pmol/L,t =9.81,7.5 1,P ＜ 0.01 ].Iodine insufficiency strongly elevated the serum TSH in LI group of mice[ (35.67 ± 17.39)mU/L] than that in control group of mice[ (0.24 ± 0.10)mU/L,t =- 6.11,P ＜ 0.01 ].The mRNA levels of TSH β-Ⅴ in BM (9.62 ± 0.60) and in PBL( 9.25 ± 0.83 ) of LI group of mice were lower than those in control group of mice (7.69 ± 0.36,7.11 ± 0.41,t =6.77,5.64,P ＜ 0.01),while the mRNA level of TSH β-Ⅴ in pituitary of LI group of mice (1.99 ± 0.61) was increased compared with that in control group of mice (5.75 ± 0.98,t =- 8.02,P＜ 0.01).Compared with control group of mice(9.12 ± 0.62),the level of thyroid TSH β-Ⅴ mRNA in LI group of mice (9.32 ± 0.91 ) was not significantly changed (t =0.45,P ＞ 0.05).There was no detectable native TSHβ in BM,PBL and thyroid.The mRNA level of native TSHβ in pituitary in LI group of mice( - 7.17 ± 1.78) was dramatically elevated compared to that in control group of mice( - 1.43 ± 0.51,t =- 7.60,P ＜ 0.01 ).ConclusionsThe mRNA levels of TSHβ-Ⅴ are suppressed in BM and PBL in low iodinediet induced hypothyroidism mice,which suggest that immune system derived TSHβ-Ⅴ may be more important thannative TSHβ in immune-thyroid regulation.

A reasonable and practicable quality standard was developed for mori liquid extract from different sources by TLC, HPLC and fingerprint technology. In TLC method, the compounds were separated on polyamide film using glacial acetic acid-water (1: 3) as mobile phase at a UV wavelength of 365 nm. All qualified samples had the spots of the same color as the control herb and substance. The RP-HPLC method was used to determine the content of mulberroside A with mobile phase of methanol-water (25: 75) at a wave-length of 326 nm. The mulberroside A was in good linear with a regression equation of Y = 46.965X (r = 0.999 6) in the range of 4.6 - 228 mg x L(-1). In 14 batches of samples, the mulberroside A in 4 batches of them was less than 0.5 g x L(-1), and was more than 2.0 g x L(-1) in the other batches. It was suggested that the content limit of mulberroside A should be no less than 1.5 g x L(-1). The HPLC fingerprints were evaluated by the similarities. It has found that the similarities of different mori liquid extracts were very low and the chemical diversity of mori cortex was the major factor of similarity. Moreover, the process impact was minimal. Thus the fingerprint was not included in this quality standard.
