OBJECTIVE: The purpose of this study was to analyzed the histopathologic spectrum and clinical features of the tumors originated from the inferior nasal turbinates. METHOD: Clinical data of 34 patients with tumours of the inferior nasal turbinates, treated from Jan. 1998 to Dec. 2012, were retrospectively reviewed. Of the 34 patients, 18 male and 16 female, aged from 25 years to 76 years (mean: 45.6yr). RESULT: (1) Pathology : Of the 34 patients, 23 (67.6%) were benign and 11 (32.4%) were malignant. Hemangiomas were the most frequent benign tumour accounting for 18/23 (78.3%) in benign tumour and for 52.9% in all the tumors originated from inferior nasal turbinates. Other benign tumours included inverted papilloma, squamous papillomas and extrapleural solitary neurofibroma tumor. The most common malignant tumour was non-Hodgkin's lymphoma accounting for 6/11 (54.5%) in malignant tumour and for 17.6% in all the tumors. Other malignant tumour included squamous cell carcinoma, melanoma and undifferentiated carcinoma. (2) Distribution: Most tumors (31/34) arose from unilateral turbinates. Hemangiomas is the commonest tumor originated from anterior part of the turbinate in 14 cases of 18 (77.8%). NHL and melanoma involved through turbinates. 3. Symtoms: Nasal obstruction was the most common symtom (25/34, 73.5%). Epistaxis and bloody nasal discharge were the chief complaint in hemangiomas. CONCLUSION 1. The most common benign and malignant tumors of the inferior turbinate were hemangioma and NHL. The majority of the hemangiomas (14/18) arose from the anterior part of the inferior turbinate. NHL or melanoma often presented progressive, unilateral or bilateral diffuse enlargement of the inferior turbinate with poor vascular contractile reactivity to the ephedrine.

Objective To investigate the changes of calcium /calmodulin - dependent protein kinase Ⅱ (CAMKⅡD) gene expression in 3T3 - L1 preadipocyte diffe-rentiation and TNF - ? regulation of CAMKⅡD gene expression on matured adipocytes. Methods 3T3 - L1 preadipocytes were cultured and differentiated into adipocytes. The levels of CAMKⅡD gene mRNA expression at various times were evaluated by RT-PCR. Matured adipocytes were interfered with 0.1,1.0,10.0 ?g/L TNF - ? and the levels of CAMKⅡD gene mRNA expression were evaluated. Results The levels of CAMKⅡD gene mRNA expression in 3T3 - L1 adipocytes were significantly down- regulated at first day, compared with those at zero day (P0. 05). CAMKⅡD gene mRNA expression decreased significantly at 12 hours after treatment with 10.0 ?g/L TNF-?, treatment of matured adipocytes with TNF - ? did not have any regulation role on it. Conclusions CAMKⅡD gene is involved in the differentiation of adipocytes and related to the etiology of obesity. The changes in the level of CAMKⅡD gene mRNA expression during 3T3 - L1 preadipocyte differentiation may contribute to the differentiation and adipogenesis of adipocytes. It seems that TNF - ? does not have any regulation role on the expression of CAMKⅡD genes.

To investigate the role of distribution and phylogeny of phenylethanoid glycoside in medicinal plants of Gesneriaceae, five phenylpropanoid glycosides, acteoside, paraboside B, isonuomioside A, paraboside II, and paraboside III were quantitatively determined in 12 species of Gesneriaceae by HPLC. The existence and content of these compounds were analyzed. The results showed that phenylethanoid glycosides were found in the most of those plants, but the kind of phenylethanoid glycosides varied in different species. Acteoside distribute in most of this plant group, paraboside B, isonuomioside A, paraboside II, and paraboside III were rare in those plants. The results of this study support morphological viewpoint that Trib. Trichosporeae is more developmental than Trib. Didymocarpeae.

To investigate the therapeutic effect of artesunate on mouse cytomegalovirus pneumonia, the BALB/c-nu mice were infected with murine cytomegalovirus-green fluorescent protein (MCMV-GFP) by nose dropping method. The experimental protocol was approved by the Medical Laboratory Animal Ethics Committee of Guangzhou Medical University. The BALB/c-nu mice were randomly divided into five groups: control group, MCMV pneumonia group, and artesunate (60, 120, and 240 mg·kg^-1) groups. The survival rate, weights, and virus loads in lungs among the groups were observed. The degree of histopathologic changes in lungs was assessed directly by hematoxylin-eosin (HE) assay. MCMV-GFP expression was assessed by immunofluorescence. In addition, reverse transcription polymerase chain reaction (RT-PCR) analysis was performed to investigate the content of major immediate early 1 (Mie1) mRNA, and enzyme-linked immunosorbent assay (ELISA) was used to detect the changes of inflammatory factors, interleukin 10 (IL-10), IL-6, and tumor necrosis factor-α (TNF-α). Western blot analysis was used to detect the expression of the changes of nuclear factor-kappa B (NF-κB) signaling pathways in total proteins. Compared with MCMV group, artesunate (120 mg·kg^-1) significantly increased body weights of MCMV-infected nude mice over 30 days, and decreased the viral titer in lung homogenate, lung inflammation, and histological severity. Moreover, the administration of artesunate (120 mg·kg^-1) could downregulate the expression of phospho-NF-κB (p-NF-κB) p65 in the lungs of mice. The present study suggested that artesunate can protect the immunocompromised mice from MCMV-induced interstitial pneumonia via downregulating NF-κB signaling pathway, thus attenuating inflammation in the lungs.

Background Ultraviolet radiation is one of factors of the formation of age-related cataract.Indole-3-carbinol(I3C) is a plant chemical material with inhibitory effect on oxidative-induced cell damage and formation of amyloid fibrils,and the oxidative damage and amyloid fibrils are associated with cataract.However,the relationship between I3C and α-crystallin is in study. Objective This study was to evaluate the effects of ultraviolet-B laser irradiation on the secondary structure of α-crystallin and to explore the protection of I3C to chaperone activity of α-crystallin. Methods The fresh eyeballs were obtained from 1-year-old cattle to prepare the purified lens α-crystallin by gel chromatography.α-Crystallin was isolated from cattle lenses using gel chromatography.The purified α-crystallin was collected using fast protein liquid chromatography ( FPLC ) and exposed to 1:308 nmultraviolet-B at different irradiation intensities ( 23.75,118.75,475.00,1187.50,2375.00,4750.00,11 875.00,23 750.00 mJ/cm2 ) and then to ultraviolet-B 2:308 nm with irradiation intensities of 28 535.00,6730.00,3435.00,1910.00,1040.00 mJ/cm2.Ultraviolet-absorbance spectra,tryptophan fluorescence and N-formylkynurenine (N-FK)fluorescence spectra of both irradiated and non-irradiated α-crystallin were measured.I3C at the concentrations of 50 μmol/L and 100 μmoL/L were added to the α-crystallin solution to perform a catalase (CAT) thermal aggregation to confirm the chaperone activity of the α-crystallin,and the α-crystallin solution without any I3C was used as control.The ratios of A360 between various intervene groups with control group were calculated using spectrophotometry.Results The A280 values of the α-crystallin declined to 10％ at the ultraviolet-B irradiation intensity of 1187.5 mJ/cm2 and that at the intensity of 23.75 J/cm2 lowed to 2％.A negative correlation was seen between the ultraviolet-B irradiation intensity and the A280 value of the α-crystallin (R2=0.925 ) and a positive correlation was found between ultraviolet-B with N-FK ( R2 =0.949 ).Ultraviolet-B irradiation intensity showed a negative correlation with Trp fluorescence intensity (R2 =0.996 ).CAT hot condensed experiment revealed that after addition of different concentrations of indole-3-carbinol,the relative A360 values at various ultraviolet-B irradiation group were significantly higher than those of the control group (P =0.000),and the decreasing degree of chaperone activity of α-crystallin was lower than that of the control group ( P =0.000 ). Conclusions The study suggests that I3C can protect the chaperone activity of α-crystallin from photooxidation,and the ultraviolet-B laser may be a good exposure source compared with ultraviolet lamp.The ultraviolet-B laser irradiation causes the alteration of structure and chaperone activity of α-crystallin.

With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.
