Objective To study the relationship between transforming growth factor-β1 (TGF-β1), transforming growth factor-β receptor Ⅰ (TGF-βRⅠ) and high concentration iodine in promoting fibroblast proliferation so as to explore the pathogenesis of the membranous formation in Budd- Chiari syndrome. Methods The experiment included five groups: blank control group, solvent group, KI group, TGF-βRⅠinhibitor group (SD-208) and SD-208 plus KI combination group. ① Fibroblasts were cultured in high content of iodine and treated with TGF-βRI inhibitor then the fibroblast proliferation activity was determined by CCK-8 assy.②The protein expressions of TGF-β1 and TGF-βRⅠof fibroblasts in different concentrations of iodine (0, 250, 500, 1 000, 2 000 and 3 000 ug/L) were determined by Western-blot method. Results ①When the culture solution was of 1 000 ug/L iodine concentration, the cell proliferation rate of the SD-208 plus KI combination group (A:1.29 ± 0.41) was significantly higher than that of the control group (0.52 ± 0.10), but significantly lower than that of the KI group(1.70 ± 0.03) with P < 0.05. ② Fibroblast TGF-β1 protein relative expression levels in the groups with the iodine concentration of 1 000 ug/L and 2 000 ug/L were significantly higher than those of the other groups (P < 0.05). No significant difference in fibroblast TGF-βRⅠ protein relative expressions existed between each other groups (P > 0.05). Conclusion ①High concentration of iodine may promote the proliferation of fibroblasts through raising TGF - β1 protein expression. ② The proliferation of fibroblasts caused by high concentration of iodine may be related to the membranous formation in Budd-Chiari syndrome.

To study in vitro anti-influenza viral activities of Chinese traditional patent medicines for influenza prevention and treatment, neuraminidase (NA) activity assay was used to examine NA inhibitory activity of 33 Chinese traditional patent medicines through fluorimetric assay, and influenza virus induced cytopathic effect (CPE) inhibition assay was used to verify their anti-influenza viral activities in vitro. The assay results showed that most liquid preparations displayed relatively high NA inhibitory activities, such as Shuanghuanglian oral liquid, Qingkailing oral liquid, Qingre Jiedu oral liquid, and Reduning injection. Among liquid preparations, Shuanghuanglian oral liquid not only displayed the highest NA inhibitory effect, but also exhibited obvious in vitro anti-viral activity in CPE experiment. Among solid preparations, Shuanghuanglian powder for injection showed the highest activity on NA inhibition, and Fufang Yuxingcao tablet showed relatively strong anti-influenza viral activity in CPE cells. From the results, it can be concluded that most Chinese traditional patent medicines possessed NA inhibitory activity, but only a few of them displayed significant in vitro anti-influenza viral activities. These results will provide important information for the isolation of active constituents, and for the clinical uses of Chinese traditional patent medicines for influenza treatment and prevention.

OBJECTIVETo investigate the use of dendritic cells derived from mice bone marrow to evaluate the cutaneous allergic reaction induced by chemical sensitizers.
METHODSDendritic cells derived from mice bone marrow were cultured and administrated with 2, 4-dinitrochlorobenzene (DNCB), nickel sulfate (NiSO4), sodium dodecyl sulfate (SDS) and hexyl cinnamic aldehyde (HCA), respectively. Cell membrane molecule CD86 and extracellular IL-1 beta, IL-6 and IL-12 were detected after 0, 1, 6, 12, 24, 36, 48 hour's administration, respectively.
RESULTSCD86 expression reached the highest level after exposure to DNCB for 48 h, and increased by about 279% compared with the control (P < 0.05), while it was lower than that of control after administrated with NiSO4 and HCA for 1 h and 6 h, and SDS for 36 h, respectively (P < 0.05). Extracellular IL-1 beta increased greatly after exposure to NiSO4 just for 1 h, with the maximum at 48 h (298 pg/ml, P < 0.05), and after exposure to HCA for 6 h, with maximum at 48 h (84 pg/ml, P < 0.05). However, it didn't fluctuate significantly after administrated with DNCB and SDS respectively, compared with the control. Extracellular IL-6 increased significantly after exposure to NiSO4 for 1 h, with the maximum at 24 h (2152 pg/ml, P < 0.05). After exposure to HCA, extracellular IL-6 reached the maximum at 1 h (1403 pg/ml), and then it was decreased quickly, but still higher than the control (P < 0.05), while it didn't change significantly after treatment with DNCB and SDS, compared with the control (P > 0.05). Extracellular IL-12 was not detected out among all the groups.
CONCLUSIONChemical sensitizer DNCB could induce the high expression of CD86 on DC membrane, and NiSO4 and HCA could induce DC to release IL-1 beta and IL-6. However, the irritant SDS had no such effect.

OBJECTIVETo study the feasibility and clinical efficacy of a minimally invasive sinus tarsi approach in the treatment of Sanders II calcaneus fractures.
METHODSFrom August of 2015 to July of 2016, 13 patients(totally 13 feet) with Sanders II intra-articular calcaneus fractures were treated via the minimally invasive sinus tarsi approach. The Böhler angle, Gissane angle and the length, width and height of calcaneus were compared between pre-operation and post-operation. The AOFAS ankle and foot scoring system of the orthopaedic ankle foot Association was used to evaluate the efficacy.
RESULTSAll the patients were followed up, and the duration ranged from 6 to 15 months, with an average of 9.5 months. No incision complications occurred. The Böhler angle was increased from preoperative (18.82±5.11)° to postoperative(26.63±4.45)°(=-4.16,=0.000). The Gissane angle was increased from preoperative(111.07±15.36)° to postoperative (124.56±8.71)° (=-2.75,=0.011). The length, width, height of calcaneus were absolutely improved from preoperative(69.82±5.95) mm, (42.07±3.68) mm, (41.20±3.90) mm to preoperatively(72.61±5.46) mm, (39.10±4.02) mm, (44.03±3.33) mm. According to the AOFAS, 8 patients got an excellent result, 4 good and 1 poor, and the postoperative mean score was 88.2±5.9.
CONCLUSIONSThe limited open sinus tarsi approach could be used successfully to treat displaced Sanders II fractures with less injury and effectively restored the surface of subtalar joint, however the method is not fit for the patients with comminuted fracture in lateral wall and great change in the length, width, height, varus and valgus of calcaneus.

Objective To examine the relationship between hyperthyroidism and excessive iodine intake from drinking water through epidemiological studies in the iodine excess and the iodine normal villages. Methods Mengzhuang village of Pei county and Xingji village of Pizhou city in Jiangsu province, with median water iodine concentration of 1284.1 μg/L and 77.9 μ/L, respectively,were selected in 2006. Thyroid diseases of all local residents in the two villages were assessed clinically to compare the prevalence and the distribution of hyperthyroidism. Results A total of 17 471 residents were recruited from the iodine excess village, 26 of them were diagnosed with hyperthyroidism. The prevalence of hyperthyroidism was 1.49‰, 0.75‰ (7/9264) in male,2.32‰( 19/8207) in female, and the age-standardized prevalence was 1.48‰. A total of 12 765 residents were recruited from the iodine normal village, among them 27 residents were diagnosed with hyperthyroidism. The prevalence of hyperthyroidism was 2.12‰, 0.96‰(7/6823) in male, 3.26‰(20/5942) in female, and the agestandardized prevalence was 2.02‰. The prevalence and age-standardized prevalence was significantly lower in the iodine excess village than those in the iodine normal village (u = 2.88, 2.89; all P < 0.01). The prevalence of hyperthyroidism was lower among females in the iodine excess village (2.32‰) than that in the iodine normal one (3.37‰, u = 2.89, P < 0.01). Residents aged 20 - 50 years had higher prevalence of hyperthyroidism[(19.36 -38.96 )/10 000]in the two villages. The proportion of Graves diseases was 50.00% (13/26) in the iodine excessvillage, higher than that in the iodine normal village[29.41%(5/17) , χ2 = 5.853, P < 0.01]. Conclusions Chronic excessive iodine intake does not increase the chance of suffering from hyperthyroidism. On the contrary, the prevalence of hyperthyroidism in the iodine excess village decreases significantly compared with that of the iodine normal village. The prevalence is higher among females.
