Objective To investigate the serum levels of Th1 and Th2 cytokines and explore its roles in development and clinical features in the elderly patients with eczema. Methods The serum levels of interleukin-2(IL-2),interleukin 4(IL-4),interleukin-10(IL-10),interleukin-12(IL-12) and tumor necrosis factor alpha (TNF-α) were derected in 50 elderly patients with eczema and 34 healthy elderly as control by enzyme-linked immunosorbent assay (ELISA). The above cytokines were compared between acute and chronic,generalized and localized eczema. Results The serum levels of IL-2 [(16.03±0.47)vs.(15.72±0.33) μg/L],IL-4[(14.04±0.56) vs.(13.56±0.16) μg/L],IL-10 [(33.01±5.40) vs.(29.49± 1.07) μg/L],IL-12 [(39.32± 3.54) vs.(37.93± 1.17) μg/L]and TNF-α [(27.33±0.72) vs.(26.38±0.48) μg/L] were higher in elderly eczema than in control (t/t'=3.55,5.74,4.49,2.58,6.69,all P＜0.05).The serum levels of all cytokines tested in acute eczema(t/t'=3.59,4.68,3.35,2.00,6.44,all P＜0.05),the levels of IL2,IL-4,IL-10 and TNF-α t'=2.46,5.50,3.83,3.10,P＜0.05,but not IL-12 (t'=1.77,P＜0.05) inchronic elderly eczema were increased as compared with control ( P ＜0.05).No significant difference was found in cytokines levels between acute and chronic eczema (P＞0.05)as well as between generalized and localized eczema(t=0.18,5.74,4.49,0.91,0.25,1.11,P＞0.05). Conclusions Changes of Th1 and Th2 cytokines may play some role in the pathogenesis of elderly eczema,but not characterized by clinical types of eczema.

OBJECTIVETo compare the early clinical effects of Activ C cervical disc replacement (ACDR) and anterior cervical discectomy and fusion (ACDF) in treating single-level cervical spondylosis.

METHODSThe clinical data of 76 patients with single-level cervical spondylosis underwent surgery from July 2009 to September 2012 were retrospectively analyzed. Among them, 28 patients were treated with ACDR (ACDR group), including 18 males and 10 females, aged from 32 to 62 years old with an average of (45.2±6.2) years; and 48 patients were treated with ACDF (ACDF group), including 28 males and 20 females, aged from 33 to 60 years old with an average of (45.8±6.4) years. Visual analogue scale (VAS), Japanese Orthopedics Association (JOA) score, Short Form-36 (SF-36), imaging data were used to assess the clinical effects after operation.

RESULTSA total of 76 patients were followed up from 6 to 24 months with an average of 13.2 months. VAS of neck pain and brachialgia were improved in all patients after operation (P<0.05), there was no significant difference between two group (P>0.05). Somato-score and psycho-score of SF-36 of two groups were obviously increased (P<0.05), ACDR group was better than that of ACDF group (P<0.05). In ACDR group, there was no significant difference in the range of motion of surgical segments and adjacent segments between preoperative and postoperative (P>0.05); heterotopic ossification around the edge of vertebral body occurred in 1 case on the 6th month after operation, no fusion was found on the 1st year after operation. In ACDF group, the adjacent vertebral disease occurred in 1 case and the patient underwent the reoperation.

CONCLUSIONActiv C cervical disc replacement can reduce the degeneration of adjacent segments and its early outcomes for the treatment of single-level cervical spondylosis are satisfactory, but the long-term effects still need study.

Purpose To investigate the diagnostic utility of the immunohistochemical markers SALL4, D2-40 and Glypican-3 in prima-ry testicular germ cell tumors (TGCTs). Methods The expression of SALL4, D2-40 and Glypican-3 protein was detected by EnVi-sion immunohistochemical method in 56 cases of primary testicular germ cell tumors, including 5 intratubular germ cell neoplasms ( IT-GCNs) , 10 seminomas, 14 embryonal carcinomas ( ECs) , 14 yolk sac tumors ( YSTs) , 1 choriocarcinoma, 5 immature teratomas and 12 mature teratomas. 10 normal testicular tissues and 5 lymphomas were selected as control. Results All of ITGCNs, seminomas, YSTs and ECs were diffusely strongly positive for SALL4. Focal SALL4 staining was seen in choriocarcinoma, 3 of 5 immature terato-mas and 3 of 12 mature teratomas. All of ITGCNs, seminomas showed diffusely strong D2-40 staining. ECs (4/14) were focally posi-tive for D2-40, while choriocarcinoma, YSTs and teratomas were negative for D2-40. Glypican-3 was diffusely positive in YSTs (13/14), and focally weakly positive in ECs (2/14), respectively. ITGCNs, seminomas, choriocarcinoma and teratoma were negative for Glypican-3. In contrast, 10 normal testicular tissues and 5 lymphomas showed no SALL4, D2-40 and Glypican-3 staining. Conclu-sions SALL4 is a useful diagnostic marker with high sensitivity and specificity for TGCTs. Combination of SALL4, D2-40 and Glypi-can-3 is helpful to the diagnosis and differential diagnosis for TGCTs.

Objective To explore the surgical management for arterial diseases. Methods The clinical data of 86 cases of arterial diseases were analysed retrospectively. These cases included:3 cases of thoracic aortic aneurysm,2 cases of descending aortic dissection with rupture and aneurysm formation,2 cases of abdominal aortic dissection with false aneurysm,1 case of abdominal aortic aneurysm(AAA)with duodenojejunal fistula and GI bleeding,5 cases of ruptured AAA with shock, 3 cases of traumatic rupture of abdominal aorta,21 cases of AAA combined with unilateral or bilateral iliac aneurysms,6 cases of iliac aneurysms,9 cases of popliteal aneurysms,21 cases of false aneurysm of iliac or popliteal artery,1 case of rupture of junction of subclavian and vertebral artery with false aneurysm,3 cases of rupture of subclavian artery with false aneurysm,2 cases of aneurysm of carotid artery and 7 cases of false aneurysm of carotid artery. Prosthetic vascular graft was performed in 71(cases),autologous vein graft in 3 cases and suture(repair) of arterial rupture in 12 cases.Results Operative (mortalty) was 3.5%(3/86)in this series.Seventy-one cases were followed-up for 1 month to 5 years, the results showed that all the patients were alive and well.Conclusions In the(management) of(appropriate) aortic diseases, the use of endoluminal technique is simple, microtraumtic, safe and has few complications. It also can shorten the hospital stay of the patient. Endovascular technique should be the first choice for patients with aortic diseases.

Background Researches demonstrated that CpG ODN,a immunostimulatory sequences,has preventing and treating effect on allergic conjunctivitis caused by protein allergen.However,its effect on allergic conjunctivitis caused by fungal allergen is unclear. Objective This study aimed to investigate into whether the Th1-Th2 switching immunostimulatory CpG ODN could reverse the response in the murine allergic conjunctivitis model caused by aspergillus fumigatus. Methods A mixture of spores and hyphae of aspergillus fumigatus strain was used to induce allergic conjunctivitis in male BALB/C mice aged 6-8 weeks.This experiment was designed into preventive or therapeutical treatment program.Under both settings,allergic conjunctivitis of the animals were treated with CpG ODN,nonstimulatory GpC ODN or PBS.After the last challenge with the allergen,the clinical symptoms of the animals were scored based on the criteria of Magone.The animals were sacrificed and the histopathological examination of conjunctiva was performed.Expression of TLR4 mRNA in conjunctiva was analyzed by real-time PCR assay.The responsiveness and populations of lymphocytes in spleen and draining lymph nodes were analyzed by flow cytometry.The use complied with the Standard of Association for Research in Vision and Ophthalmology. Results In the prevention mode.CpG ODN decreased subconjunctival infiltration compared with GpC ODN and PBS groups with the average neutrophil count index(21.25 ±11.59/section,30.75 ±11.44 section and 69.00±9.90/section,respectively).Expression of TLR4 mRNA was up-regulated significantly by CpG ODN.The clinical scores for CpG ODN group were insignificantly lower than those in GpC ODN group and PBS group(P＞0.05).In the therapeutic mode,compared with GpC ODN and PBS groups,the allergic symptom score in CpG ODN group manifested significantly lower(t=4.000.t=2.750,P＜0.01)and showed fewer cellular infiltration(t=4.870,t=3.829,P＜0.01)and higher expression of TLR4 mRNA(P＜0.01).In cultured splenic and draining lymph node cells,increased percentages of CD4+ CD25+ and CD4+ CD25+ CD69+ in CpG ODN group were observed compared with control groups(|P＜0.05). Conclusion CpG ODN can relieve aspergillus fumigatus-induced allergic conjunctivitis via either subconjunctival injection or topical application by upregulating expression of TLR4 and activating Treg lymphocytes.

Objective To explore the regulative effect of α-Hederin on the proliferation and invasion of NSCLC and investigate its related molecular mechanism. Methods After A549 and HCC-1833 cells were treated with a concentration gradient of α-Hederin for 24 and 48 h, the OD_450nm was detected by using CCK8 assays, and the IC₅₀ was calculated.The A549 and HCC-1833 cells were divided into the blank control and α-Hederin groups in accordance with IC₅₀ values.Cell proliferation was detected by EdU assays, and cell cycle transformation and cell apoptosis were detected by flow cytometry.Cell mobility was detected by using Transwell and scratch assays.SREBP1 and FASN protein expression levels were detected through Western blot analysis, and cell lipid accumulation was detected via oil red O staining. Results The survival rate of lung cancer cells decreased significantly with the increase of α-Hederin concentration, and the IC₅₀ values of A549 and HCC-1833 cells at 48 h were 15 and 25 μg/ml, respectively.Compared with the blank control group, cells proliferation and migration were significantly inhibited, cells were blocked in the G₁/S phase, the apoptosis rate increased, and the protein expression and lipid accumulation of SREBP1/FASN significantly reduced after α-Hederin treatment. Conclusion α-Hederin can inhibit the proliferation and migration, G₁/S phase transition and induce the apoptosis of NSCLC cells and hinder the malignant progression of NSCLC by downregulating the expression of SREBP1 and FASN and reducing the accumulation of cell lipids.
