AlM: To analyze, summarize and describe ophthalmic imaging features of posterior scleritis.
METHODS: Clinical data of 16 patients ( 21 eyes ) with posterior scleritis diagnosed in our hospital from October 2008 to June 2013 were retrospectively analyzed. The results of type-B ultrasonic, fundus chromophotograph, fundus fluorescein angiography, CT were recorded for comprehensive evaluation and analysis of ophthalmic imaging features of posterior scleritis.
RESULTS: All patients underwent type-B ultrasonic examination and manifested as diffuse and nodular types. The diffuse type showed diffusely thickened sclera and a dark hypoechoic area that connected with the optic nerve to form a typical “T”-shaped sign. The nodular type showed scleral echogenic nodules and relatively regular internal structure. FFA showed that relatively weak mottled fluorescences were visible in the arterial early phase and strong multiple needle-like fluorescences were visible in the arteriovenous phase, which were then progressively larger and fused; fluorescein was leaked to the subretinal tissue in the late phase;varying degrees of strong fluorescences with less clear or unclear boundaries were visible in the optic disk. CT results showed thickened eyeball wall.
CONCLUSlON: Posterior scleritis is common in young female patients, whose ophthalmic imaging features are varied and more specific in type-B ultrasonic. Selection of rational ophthalmic imaging examination method, combined with clinical manifestations, can accurately diagnose posterior scleritis and avoid the incidence of missed and delayed diagnosis.

OBJECTIVETo search for the best therapy for recurrent herpes simplex.

METHODSNinety-six cases were randomly divided into an auricular point sticking plus moxibustion group (treatment group, n = 54), a medication group (control group, n = 42). The treatment group were treated with auricular sticking at points Spleen, Lung, Kidney, and others, and moxibustion was applied at Zusanli (ST 36), Fenglong (ST 40), and local blister; the control group were treated by oral administration and external application of aciclovir.

RESULTSThe cured rate and the total effective rate were 55.5% and 100.0% in the treatment group, and 9.5% and 61.9% in the control group, respectively, with a significant difference between the two groups (P<0.05).

CONCLUSIONThe auricular point sticking plus moxibustion is a better therapy for recurrent herpes simplex, with a significantly better therapeutic effect than that of the medication.

To determine the optimum conditions of supercritical CO2 extraction of Xiaoyaosan, and establish its fingerprint by gas chromatography-mass spectrometry (GC-MS), the yield of extract were investigated, an orthogonal test was used to quantify the effects of extraction temperature, pressure, CO2 flow rate and time, and fingerprint analysis of different batches of extracts were by GC-MS. The optimal extraction conditions were determined as follows: extraction pressure 20 MPa, extraction temperature 50 degrees C, CO2 flow rate 25 kg x h(-1), extraction time 3 h, and average yield 2.2%. The GC-MS fingerprint was established and 27 common peaks were found, whose contents add up to 81.89% of the total peak area. Among them, 21 compounds were identified, accounting for 53.20% of the total extract. The extraction process is reasonable and favorable for industrial production. The GC-MS method is accurate, reliable, reproducible, and can be used for quality control of supercritical CO2 extract from Xiaoyaosan.

ObjectiveTo observe the influence of iodine on mRNA expression of iodide transporter (NIS),insulin-like growth factor Ⅰ (IGF- Ⅰ ) and transforming growth factor beta(TGF-β) in thyroid and mammary glands of lactating rats and to explore the role of NIS,IGF- Ⅰ and TGF-β mRNA in iodine uptake in thyroid and mammary glands of lactating rats.MethodsOne hundred and one Wistar rats(80 female and 21 male),weighting 8 - 100 g were selected.These female rats were randomly divided into five groups according to their body weight:control group(NI,normal feed,drank deionized water containing iodine 50 μg/L) ; low iodine group 1 and 2(LI-1,LI-2,low iodine feed,drank deionized water containing iodine 0 and 5 μg/L,respectively); high iodine group 1 and 2(HI-1,HI-2,normal feed,drank deionized water containing iodine 3000 and 10 000 μg/L,respectively),16 rats in each group.After feeding for 3 months,the female and male rates were mated 3:1.The female rats in each group were sacrificed at the fifth and tenth day after postpartum.Thyroid and mammary glands were taken.The mRNA levels of NIS,IGF- Ⅰ and TGF-β in thyroid and mammary glands of lactating rats were determined by real time quantitative PCR.ResultsThe fifth days after postartum,NIS,IGF- Ⅰ and TGF-β mRNA expression levels of thyroid and lactating mammary glands were different between groups,and the differences were statistically significant ( NIS:F =631.46,64.91,all P ＜ 0.01 ; IGF- Ⅰ:F =11.45,6.56,all P ＜ 0.01 ; TGF-β:F =291.83,304.53,all P ＜ 0.01).Compared with control group [NIS:0.0066 ± 0.0023, (0.1481 ± 0.0711 ) × 10-2; IGF- Ⅰ:0.0419 ± 0.0062,0.0542 ± 0.0044; TGF-β:0.1416 ± 0.0277,0.1670 ± 0.0499],regardless of thyroid or mammary gland,the NIS,IGF- Ⅰ and TGF-β mRNA expression of LI-1 [NIS:0.0447 ± 0.0110,(0.3030 ± 0.1831) × 10-2;IGF- Ⅰ:0.0662 ± 0.0078,0.0902 ± 0.008; IGF- Ⅰ:0.5514 ± 0.0508,0.6942 ± 0.0367],LI-2[NIS:0.0317 ±0.0081,(0.3017 ± 0.1601) × 10-2; IGF-I:0.0645 ± 0.0054,0.0894 ± 0.0093; TGF-β:0.5292 ± 0.0332,0.6704 ± 0.0277 ] was significantly increased (all P ＜ 0.01 ); the NIS mRNA expression of HI-1 [0.0043 ± 0.0011,(0.1233 ± 0.0954) × 10-2],HI-2[0.0037 ± 0.0017,(0.1058 ± 0.0854) × 10-2] was decreased(all P ＜ 0.05),while the expression of IGF-Ⅰ mRNA [0.0521 ± 0.0910,0.0715 ± 0.0026; 0.0516 ± 0.0078,0.0697 ± 0.0038] and TGF-β mRNA [0.2087 ± 0.0425,0.2361 ± 0.0425; 0.1971 ± 0.0237,0.2257 ± 0.0752 ] was increased (all P ＜ 0.05 ).The tenth days after postpartum,the mRNA expression levels of NIS,IGF- Ⅰ and TGF-β of thyroid and lactating mammary gland in rats were different between groups,and the differences were statistically significant (NIS:F =103.55,116.32,all P ＜ 0.01; IGF-Ⅰ:F =67.67,11.98,all P ＜ 0.01; TGF-β:F =74.30,381.30,all P ＜0.01 ).Compared with the control group[NIS:0.0069 ± 0.0011,(0.1337 ± 0.0599) × 10-2; IGF-Ⅰ:0.0390 ±0.0071,0.0534 ± 0.0056; TGF-β:0.1351 ± 0.0336,0.1534 ± 0.0320],the mRNA expression levels of NIS,IGF- Ⅰ and TGF-β of LI-1 [ NIS:0.0432 ± 0.0165,(0.2962 ± 0.0985 ) × 10-2; IGF- Ⅰ:0.0643 ± 0.0088,0.0873 ± 0.0055 ; TGF-β:0.5042 ± 0.0912,0.6408 ± 0.0420],LI-2[NIS:0.0287 ± 0.0111,(0.2873 ± 0.0862) × 10-2; IGF- Ⅰ:0.0621 ± 0.0094,0.0862 ± 0.0038; TGF-β:0.4893 ± 0.0504,0.6372 ± 0.0389] were significantly increased(all P ＜ 0.01 ); the NIS mRNA levels of HI-1 [ 0.0042 ± 0.0029,(0.1006 ± 0.0909) × 10-2],HI-2[0.0035 ± 0.0020,(0.0890 ± 0.0119) × 10-2] were decreased(all P＜ 0.05),while the expression of IGF-Ⅰ mRNA[0.0516 ± 0.0078,0.0668 ± 0.0071; 0.0508 ± 0.0089,0.0621 ± 0.0064] and TGF-β mRNA[0.2007 ± 0.0546,0.2175 ± 0.0370;0.1959 ± 0.0393,0.2097 ± 0.0425] were increased(all P ＜ 0.05 ).In thyroid and mammary glands,the comparisons of NIS,IGF,TGF-β mRNA expression of the fifth and tenth day after postartum,between each group were not statistically significant(all P ＜ 0.05).ConclusionsThere are regulatory mechanisms of thyroid and mammary glands of lactating rats in response to low or high iodine conditions.In low iodine,the expressions of NIS,IGF- Ⅰ and TGF-β mRNA in thyroid and mammary glands increase and iodide uptake ability is enhanced to meet the body needs.In high iodine,the expression of NIS mRNA decreases in thyroid and mammary glands.Due to the reduced ability of iodine uptake,iodine intake is reduced,thereby reducing the hazards of high iodine in filial rats.

Patients with multiple myeloma (MM) have increased constantly in recent years, but treatment for patients with MM is currently unsatisfactory and it is necessary to develop new complementary therapies. Dendritic cells (DCs) are specialized antigen-presenting cells capable of initiating and regulating immune responses. Vaccination with tumor antigen-pulsed DCs has shown to be safe and possesses therapeutic effect against many tumors. In this review, the various types of MM-associated antigens and clinical trials on DC-based immunotherapy in MM are summarized, the development of DC immunotherapy for MM patients in future trials is discussed.
