Objective To produce a hybridoma secreting stable monoclonal antibodies against Aβ22-35 and to develop a detection method for the assay of Aβ. Methods Spleen cells from Balb/cmice immunized with Aβ22-35-KLH were fused with mouse myeloma cells SP2/0. The techniques of immunoprecipitation and western blotting plus ECL were used to investigate the levels of Aβ in the rat brain. Results Two strains of hybridomas (3A8 and 3B2) secreting stable monoclonal antibodies raised against Aβ22-35 were obtained. The subtypes of Aβ22-35 were IgG3. The levels of Aβ in young and older rat brain were 9.8±2.8 and 13.36±2.65 (pmol/12mg brain tissues, x±s), respectively. Conclusion The Aβ22-35 mAb obtained had high titres and specificity. The levels of Aβ in the older rat brain were significantly increased as compared with the young one (P＜0.05).

Objective To analyze the clinical features and common etiology of lung nodules in children. Methods The etiology, diagnosis, radiological features from 98 hospitalized children of lung nodules were analyzed. Results Of them, 58 were male and 40 were female aged from 0.2 years old to 14.8 years old. Pulmonary infection were found in 41 cases (41.8%) including tuberculosis in 15 cases (15.3%), pulmonary fungal infection in 13 cases (13.3%), pneumonia in 11 cases (11.2%), lung trematode in 2 cases (2.0%). Pulmonary metastases were found in 28 cases (28.6%), multiple pulmonary arteriovenous fistula in 1 case (1.0%), and pulmonary contusion in 1 case (1.0%) and unknown etiology in 27 cases (27.6%). Conclusions The etiology of lung nodules is complicated, in which infectious diseases are the most commonly seen, followed by pulmonary metastases. Biopsy is the golden standard of diagnosis.

Background It is well known that the diminution of visual acuity appears before notable complications in some high myopic eyes.However,whether the impaired vision is associated with the change of retinal thickness at macula area is still under investigation.Objective This study was to investigate the relationship of macular retinal thickness with the change of visual acuity in high myopic eyes.Methods A consecutive caseobservational study was performed.Two hundred and forty-five eyes of 132 patients with the diopter of-6.00～-20.00 D were enrolled in this study during the January 2011 to January 2012 in Beijing Tongren Eye Center.All of the patients received the measurement of retinal thickness with Fourier Domain Optical Coherence Tomography (FDOCT),and the scan mode was MM6.The eyes were divided into the corrected vision ≥0.9 group and the corrected vision ≤0.8 group.In addition,the eyes were assigned to the non-posterior staphyloma group,posterior staphyloma Ⅰ group (macular symmetry) and posterior staphyloma Ⅱ group (macular gradient).The retinal thicknesses in different quadrants at the macular zone were measured and calculated by OCT software.Results The demography was matched in different groups.Corrected visual acuity was significantly increased in the corrected vision ≥ 0.9 group than that in the corrected vision ≤0.8 group (1.02±0.16 vs.0.62±0.08) (t=3.233,P=0.001).Retinal thickness value at fovea was (256.28±13.19) μm in the corrected vision ≥0.9 group,and that in the corrected vision ≤0.8 group was (231.17 ± 10.96) μm,with a significant difference between the two groups (t =2.134,P =0.031).The corrected visual acuity was 1.00±0.27,0.78±0.21 and 0.90±0.13 in the non-posterior staphyloma group,posterior staphyloma Ⅰ group and posterior staphyloma Ⅱ group,respectively,showing significant difference among the three groups (F=15.760,P=0.015),and the corrected visual acuity of the non-posterior staphyloma group and posterior staphyloma Ⅱ group were significantly higher than that of posterior staphyloma Ⅰ group (q =16.131,P =0.006 ; q =-10.831,P=0.008).A significant difference also was seen in the mean retinal thickness among the three groups (F=2.316,P =0.025).The mean retinal thickness in the posterior staphyloma Ⅰ group was (234.21 ± 15.69) μm,which was significantly smaller than (252.25± 15.31) μm of the posterior staphyloma Ⅱ group (q =12.977,P =0.023).There were no significant difference in the retinal thickness at para-fovea area among the three groups (F=0.318,P =0.078).However,significant difference was found at peri-fovea area in different groups (F=1.925,P =0.013).The mean retinal thicknesses at peri-fovea area was (273.26 ± 16.37) μm in the posterior staphyloma Ⅱ group and was significantly smaller than (289.11 ± 19.30) μm of the posterior staphyloma Ⅰ group and (290.33 ± 17.12) μm of the non-posterior staphyloma group (q =-8.305,P =0.023 ; q =-7.011,P =0.012).Conclusions The retinal thickness at fovea is associated with the corrected visual acuity in high myopic eyes.The thinning of retinal thickness at the vertex of posterior staphyloma is one of causes of visual function impairment.

Compound Wuzhigan capsules is a compound preparation composed of Wuzhigan, Shidagonglao, Gangmei, Shanzhima. A Randomized, double-blind, multi-center, positive parallel control designed to evaluate the clinical efficacy and safety of compound Wuzhigan capsules on anemopyretic cold. One hundred and twenty anemopyretic cold patients were given compound Wuzhigan capsules (test group), 2 capsules one time, three times a day, 119 patients were given compound Wuzhigan tablets (control group) ,4 tablets one time, three times a day; three days of treatment The study showed, the markedly effective rate and total effective rate respectively were 63. 3% and 80% of the test group. For the control group, the markedly effective rate and total effective rate respectively were 72. 5% and 80. 7%. The difference was not statistically significant. Compound Wuzhigan capsules can reduce the dosage, and get better patient compliance.

OBJECTIVETo observe monocyte (Mo) development in wild type C57BL/6 mice and apoE gene knockout (apoE(-/-)) mice, and to evaluate the immuno-regulatory effect of Huanglian Jiedu Decoction (HJD) on peripheral Mo development in apoE(-/-) mice.

METHODSFour, 8, 12, and 16 weeks old female C57BL/6 mice were set up as control groups of different ages, while 4, 8, 12, and 16 weeks old female apoE(-/-) mice were set up as hyperlipidemia groups of different ages. Four-week old female C57BL/6 mice were recruited as a blank group. Four-week old female apoE(-/-) mice were randomly divided into the control group, the Western medicine group, and the Chinese medicine group by paired comparison, 5 in each group. Equivalent clinical dose was administered to mice according to body weight. Mice in the Western medicine group were administered with Atrovastatin at the daily dose of 10 mg/kg by gastrogavage, while those in the Chinese medicine group were administered with HJD at the daily dose of 5 g/kg by gastrogavage. Body weight was detected each week. After 4 weeks blood lipids levels (such as TG, TC, LDL-C, and HDL-C), and the proportions of Mo and Ly6c(hi) were detected.

RESULTSCompared with 4-week-old homogenic mice, the proportion of Mo decreased in 16-week-old C57BL/6 mice (P < 0.05). Levels of TC and TG, and the proportion of Ly6c(hi) subtype increased, but the proportion of Mo de- creased in 8-week-old apoE(-/-) mice (P <0. 05). Levels of TC, TG, and LDL-C increased in 12-week-old apoE(-/-) mice (P < 0.05). Levels of TC, TG, LDL-C, and HDL-C increased in 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01). Compared with 8-week-old homogenic mice, the proportion of Mo decreased in 16-week-old C57BL/6 mice (P < 0.05); levels of TC and LDL-C increased in 12-week-old apoE(-/-) mice (P < 0.05); levels of TC and HDL-C increased in 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01). Compared with C57BL/6 mice of the same age, TC and TG increased, HDL-C decreased (P < 0.01) in 4-and 8-week-old apoE(-/-) mice (P < 0.01); levels of TC, TG, LDL-C increased, and HDL-C level decreased in 12- and 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01); the proportion of Mo increased in 4-week-old apoE(-/-) mice (P < 0.05); proportions of Mo and Ly6c(hi) increased in 8-week-old apoE(-/-) mice (P < 0.05). Compared with the blank control group, levels of TC, TG, and LDL-C, proportions of Mo and Ly6c(hi) increased (P < 0.01, P < 0.05), but HDL-C level decreased (P <0. 01) in the control group after intervention. Compared with the control group, body weight gained less in the Western medicine group and the Chinese medicine group (P < 0.05); the proportion of Ly6c(hi) subtype decreased in the Chinese medicine group (P < 0.05).

CONCLUSIONSIn development process blood lipids levels in apoE(-/-) mice are not only associated with age. Blood lipids levels induced growth changes in natural immune system are also correlated with age. In early stage of lipids development HJD intervention could correct this special immune disorder in apoE(-/-) mice.
