IgG4 related disease (IgG4-RD) is a systemic disease which was named and accepted in recent years.IgG4-RD is a multiorgan-involved disease, mainly including pancrease, parotid gland, bile duct, liver, etc.The study on the relationship between IgG4 and orbital disease is relatively few.In recent years, our study group aimed directly to the relationship between IgG4 and common orbital disease, including benign lymphoepithelial lesion of lacrimal gland,idiopathic orbital inflammatory pseudotumor, orbital lymphoma, etc.We found that IgG4 was associated with the pathogenesis and progression of these diseases.This article addressed systematically the pathogenesis of IgG4 related orbital disease and evaluated the values of IgG4 in diagnosis,differential diagnosis,treatment and montoring of these orbital diseases based on related literature and reseaching results from our study group,in order to deepen the recognition of IgG4 related orbital diseases in ophthalmologists.

Objective To report the clinical features and effects of internal fixation with anatomical plate in combination with bone graft in treatment of complicated comminuted fractures of distal femur. Methods There were 11 case of type C2 and 9 cases of type C3 fractures of distal femur according to the AO classification. When they were treated with anatomical plate, bone grafting from ilium or fibula or from both was done to repair their bone defects depending on specific defects of the patients. Results All the patients were followed up for a mean of 20 months (ranging from 10 to 24 months). Bone healed in all the cases. By Schatzker standards, the result was excellent in 14 patients, good in 5 and fair in 1. The excellent and good rate was 95%. Conclusion The authors consider that anatomical plate in combination with bone graft is an ideal treatment for complicated comminuted fractures of distal femur.

Objective To study the role of polyamines(putrescine,spermidine and spermine) in regulating ornithine decarboxylase(ODC) protein levels in the early regenerating liver of rats. Methods Exogenous polyamines(dissolved in 0.9% NaCl) were administered subcutaneously to adult male SD rats(180～220g).The ODC protein levels in the regenerating liver induced by partial hepatectomy(PH) were measured by Western blotting analysis. Results The treatment with high doses of putrescine( 20 mg/kg body weight),spermidine(0.15 mg/kg body weight) or spermine(6 mg/kg body weight) reduced the ODC protein level compared with the control group within 12 hours after PH.However,the treatment with low doses of putrescine(0.02 mg/kg),spermidine(0.03 mg/kg) or spermine(0.06 mg/kg) resulted in a rapid increase in the protein level in the 4th hour after PH,which was 15.1%,29.5% or 30.3% higher than that of control rats respectively.Conclusion Polyamines with certain doses play a role in the feedback regulation of ODC protein levels in the early regenerating liver,where spermidine and spermine play a greater role than putrescine dose.

Calli were induced from young leaves,immature seeds and hypocotyl of Swertia mussotii Franch.Three kinds of media,MS,B5 and N6 were set up in the experiment. Calli were established with the highest frequency on to MS medium cantaining 3mg/L 2,4-D and 0. 6mg/L KT.The induction antmaintenence of the calli were affected markedly by the basic media and compound 2,4-D and KT in the media which proved that asextual reproduction of S. mussotii is possible by tissue culture

Objective To investigate the preoperative design and application of the minimum foveolar translocation distance and angle of macular translocation. Methods The fundus fluorescein and indocyanine green angiographies were performed on 53 eyes of 53 patients with classic subfoveal choroidal neovascularization (SCNV), including 42 with exudative age-related macular degeneration and 11 with high myopic macular degeneration. The actual area of macular SCNV and the minimum foveolar translocation distance and angle were analyzed. Results The actual area of SCNV was 0.39~18.00 mm 2 with the mean of (3.08?3.22) mm 2. The designed minimum superior translocation distance was 67~2 240 ?m with the mean of (845.72?425.23) ?m;the minimum designed minimum inferior translocation distance was 53~ 2 430 ?m with the mean of (912.17?547.77) ?m. The minimum designed superior translocation angle was 1~32? with the mean of (13.23?6.68)?;the minimum designed inferior translocation angle was 1~35? with the mean of (14.06?8.46)?. The individual difference of the minimum designed superior and inferior translocation distance was more than 500 ?m in 16 eyes (30.19%), and the difference of translocation angle was more than 10? in 11(20.75%). Conclusion Preoperative design of minimum translocation distance and angle of macular translocation may be helpful to choose the operation program.

Objective To study the expression of endothelin 1 (ET 1) mRNA in keratinocytes in patients with vitiligo. Methods Fourteen patients with progressive vitiligo were measured by hybridization in situ. Results Our results showed that the expression of ET 1 mRNA was markedly decreased. Conclusion The results revealed that decreased ET 1 expression may be associated with the pathogenesis of vitiligo. The cause and role of decreasing of ET 1 expression of keratinocyte in vitiligo lesion need to be studied further.

Methods Simultaneous ICGA and FFA were performed on 32 eyes of 31 AION patients and 38 eyes of 38 non AION patients. Results The eyes that all or a part of the optic disc lies in the watershed zones of the choroidal blood supply were significantly more in the AION group than those in the non AION group (P

Objective To observe the effect of febuxostat on IL-1β, TNF-αand COX-2 in gout patients.Methods 82 patients with gout in our hospital from August 2015 to August 2016 were divided into the groups of 40 mg/day of febuxostat and 80 mg/day of febuxostat randomly, 41 cases respectively.Select the same period in our hospital health examination of 41 cases.The levels of serum uric acid were measured before and after one week, two weeks and four weeks after treatment.Serum levels of IL-1β, TNF-αand IL-1βin serum were measured by enzyme-linked immunosorbent assay (ELISA) COX-2 levels.Results The levels of serum uric acid in the group of 40 mg/day vs 80 mg/day of febuxostat were (570.4 ±70.5) μmol/L and (572.8 ±71.2) μmol/L, significantly higher than the normal group (296.5 ±9.7) μmol/L (P<0.05), serum uric acid level decreased gradually with the time of administration, and the serum uric acid levels of the two dosages of fosobutamol at one,two,four weeks were significantly lower than before treatment (P<0.05), but not to below the normal level.The IL-1βof 40 mg/day and 80 mg/day of febuxostat was (40.5 ±6.8) pg/mL and (41.7 ±7.2) pg/mL, COX-2 were (15.5 ±1.7) pg/mL and (15.8 ±1.8) pg/mL respectively, significantly higher than the normal group (8.8 ± 1.7) pg/mL (P<0.05), The expression of IL-1βwas significantly decreased at the second week of IL-1βdecreasing as the time of IL-1βdecreased gradually (P<0.05); TNF-αin 40 mg/day group and 80 mg/day group was significantly lower than that before treatrment (P<0.05), but not to below the normal level.Conclusion Febuxostat can significantly reduce serum uric acid levels in patients with gout, and may reduce IL-1β, TNF-αand COX-2 and other cytokine levels.

Objective To compare the clinical efficacy of laparoscope and open operation in treatment of adrenal pheochromocytoma.Methods 52 cases with adrenal pheochromocytoma were randomly divided into two groups,they were treated with laparoscope or open operation.Intraoperative blood loss,intraoperative blood pressure and heart rate fluctuations,operation time,drainage,hospitalization and postoperative complications were compared between two groups.Results Intraoperative comparison:In laparoscope group,operative blood loss was (65.7 ± 50.2) ml,blood pressure fluctuations in 1 case (3.8％),heart rate variability was (18.7 ± 6.1)/min and the operation time was (93.7 ± 21.7) min; in the open operation group,amount of bleeding during the operation was (240.4 ± 150.5) ml,blood pressure fluctuations in 7 cases(26.9％),heart rate variability was (25.6 ± 6.3)/min and the operation time was (137.7 ± 30.5) min,the differences between the two groups was significant (t =3.15,x2 =5.32,t =3.65,t =4.16,all P＜0.05).The maximum tumor diameter of open operation group was (7.3 ± 1.4) cm,which was bigger than that of the laparoscope group (6.6 ± 1.2) cm,but no significant difference between two groups (P ＞ 0.05).Postoperative comparison:in the laparoscope group,postoperative drainage was (174.3 ± 121.3)ml,drainage time was (4.3 ± 1.3) d and time of hospitalization was (8.4 ± 1.2) d,which were significantly less than those in open operation group(318.5 ± 132.6)ml,(8.7 ±2.3)d and (11.4 ±3.2)d(t =2.54 3.13,2.12,all P ＜0.05).No serious complications were observed in two groups,laparoscope group 1 case,open operation group 5 cases had postoperative pain,after the corresponding symptomatic treatment was improved.After 3 months of follow-up,clinical symptoms were significantly improved or disappeared,ultrasound or CT reexamination found no recurrence.Conclusion Laparoscope in treatment of adrenal pheochromocytoma not only has definite curative effect,but also has small trauma,shorter operation time and less complications,it is worth clinical application.

The arginine vasopressin (AVP) and oxytocin (OT) in thymic nurse cells (TNCs) of mice were stained by the method of immunogold and indfrect immunofluorescence, PAP immunocytochemical technique. TNCs of mice were shown immunocytochemical reactivity with antfserum of AVP and OT. The posttive areas were much denser near the cells membrane and around TNC-lymphocytes (TNC-Ls). It was implicated that TNCs might serve as neuroendocrine cells and might play a role in TNC-Ls differentiation via secreting AVP and OT.
