OBJECTIVETo study the anti-immune inflammation efficacy and toxicity of Tripterygium wilfordii decoction, in order to provide experimental basis for studies on its "efficacy-toxicity" correlation.

METHODThe delayed hypersensitivity model was established by dinitrofluorobenzene in mice. Different doses of T. wilfordii decoction was administered for 5 consecutive days. The ear swelling inhibition ratio and the toxic action were observed. After the final administration, the biochemical indexes of PGE2, TNF-α, IL-2, ALT, AST, PA, TBA, TBIL in serum were detected, and the visceral indexes of heart, liver, spleen and kidney were measured.

RESULTThe DNFB-induced ear swelling could be notably inhibited by multiple oral administration of T. wilfordii decoction, with the ED50 and its 95% confidence limit of 0.34 (0.21-0.42) g x kg(-1). The contents of PGE2, TNF-α, IL-2 in serum decreased in a dose-dependent manner. The activities of serum AST, ALT, TBA, TBIL and the PA content reduced.

CONCLUSIONT. wilfordii decoction shows a significant anti-immune inflammation efficacy within the dosage range between 0.59 and 2.34 g x kg(-1) in a dose-dependent manner. With a certain hepatotoxicity, high dose (2.34-4.68 g x kg(-1)) of T. wilfordii decoction can cause substantial liver injury, with a dose dependence in liver function index. Therefore, the efficacy and toxicity of T. wilfordii is dose dependent, which provides reference for preventing adverse drug reactions in clinic and developing early-warning schemes and ensure the clinical medication safety of T. wilfordii.

Wet age-related macular degeneration (AMD) is one of major causes of blindness in elder people.Intraocular injection of anti-vascular endothelial growth factor (VEGF) -A regimen has made big breakthrough for the treatment on choroidal neovascularization of wet AM D,while long-term follow-up and necessary retreatments are the key issues to remain obtained visual acuity.Multiple strategies of wet AMD have been used in following-up and retreating based on the visual acuity,optical coherence tomography (OCT),ophthalmoscope and fluorescein fundus angiography (FFA) in abroad.However,there also are major differences in the patient' s composition,treatment habits and distribution of medical sources in China from Western.So we suggest to standardize the follow-up and retreatment strategies about intravitreal injection of VEGF-A for wet AMD as to achieve a better effectiveness.OCT-guided individual follow-up and retreatment strategies should be very helpful for maintaining a long-term efficacy,minimizing the treatment time and reducing medical cost.

Objective:To compare of the effects of laparoscopic and open radical hysterectomy on the serum Interleukin-4(IL-4),interleukin-10 (IL-10),tumor Necrosis Factor-α (TNF-α) and Interferon-γ (IFN-γ) levels of Patients with Cervical Cancer.Methods:64 patients of cervical cancer who were treated from March 2014 to September 2016 in our hospital were selected as research objects.The patients were randomly divided into the abdominal cavity group and open group.The operative time,blood loss,postoperative ventilation time and the levels of IL-4,IL-10,TNF-a and IFN-γin serum before and after treatment were compared between the two groups.Results:The intraoperative blood loss and postoperative ventilation time were significantly lower or shorter in the abdominal cavity group than in the open group (P＜0.05).There was no statistically significant difference in the operation time between the two groups (P＞0.05).There were no significant differences in the levels of serum IL-4,IL-10,TNF-α and IFN-γ between the two groups before operation(P＞0.05);The serum IL-4 level was significantly lower than that of the open group during the operation (P＜0.05).There was no significant difference in the other three index between the other three groups and the laparotomy group (P＞0.05).The serum levels of IL-4,IL-10,TNF-α and IFN-γ in the abdominal cavity group were significantly lower than those of the laparotomy group on the 1 st and 7th day after operation(P＜0.05).Conclusion:Laparoscopic radical mastectomy in cervical intraoperative less blood loss and more secure.The effect of IL-4,IL-10,TNF-α and IFN-γin the postoperative patients was more obvious.Conducive to the recovery of patients after surgery.

Objective To investigate the CT features of pulmonary sarcoidosis.Methods Ninety patients with histologically proved pulmonary sarcoidosis were retrospectively studied by using CT scans and clinical recording.Results The main CT findings of pulmonary sarcoidosis were nodules which were seen in 69 cases(76.7%),and the nodules mostly distributed around the bronchovascular bundle(n=37, 41.1%).Other abnormalities included consolidation(n=31,34.4%),ground-grass(n=39,43.3 %), thickening of bronchovascular bundle(n=30,33.3%),interlobular septal lines(n=58,64.4%), fibrosis(n=17,18.9%)including bronchial distortion(n=8,8.9%),linear shadow(n=5,5.6%), and honeycombing shadow(n=4,4.4%),air-trapping(n=3,5.3%),bronchial straitness(n=8, 8.9%),pleural thickening(n=42,46.7%),and hilar and mediastinal adenopathy(n=76,84.4%). Two or more abnormal findings co-existed in 83 cases.The pulmonary lesions co-existed with hilar and mediastinal adenopathy in 76 cases.The nodules(n=25),consolidation(n=9),ground-grass(n=11), thickening of bronehovascular bundle(n=10)were improved after therapy.Ten cases of the interlobular septal(10/22),0 of bronchial distortion(0/4),1 case of diffuse linear(1/3),and 0 case of honeycombing(0/2)were improved.Conclusion CT manifestations of pulmonary sarcoidosis are varied, but has some specific radiographic features.A correct diagnosis can be made.combined with hilar and mediastinal adenopathy.

Objective To investigate the histological and biochemical responses associated with periprosthetic osteolysis,including the changes of tumor necrosis factor-?(TNF-?),osteoprotegerin(OPG) and os- teoprotegeria ligand (OPEL) in the interface membrane in rat models so as to understand the mechanisms of these interactions.Methods Twenty-four male SD rats were used in this study.A titanium alloy plug was inserted into each distal femur through the knee joint.Polyethylene particles were injected into the left knee at 2,4,6,8 and 10 weeks after implantation of the plugs.Saline solution was injected into the right knee as the control.The animals were killed 12 weeks after implantation.The distal femur was taken from each knee to make histological sections. The samples were made decalcified and stained with hematoxylin and eosin.The histopathological changes were observed under a light microscope.The concentrations of TNF-?in the membrane were assayed by a ELISA kit and the mRNA expressions of OPG and OPEL extracted from the tissue around the plug were detected by RT-PCR. Results The interface membrane taken from the experimental side was found to contain extensive fibrous tissues which extended deeply into the surrounding hone.TNF-?concentrations in the membrane of the experimental side were higher than in the control membrane.There was a significant decrease of OPG mRNA and a significant increase of OPGL mRNA in the membrane around the plug at the experimental side compared with the control side.Con- clusions Polyethylene particles can induce inflammatory responses around the titanium alloy plug.The increase of OPGL expression and reduction of OPG expression in membrane at the experimental side may be induced by TNF-?. Such changes might contribute to the differentiation of osteoclasts and result in the periprosthetic osteolysis.
