Objective To study the level of immunoglobulin and the prevalence of ANA in patients with Graves' diseases(GD).To explore the correlation between GD and other systemic autoimmune disorders.Methods Data of 145 patients with GD and 45 healthy subjects were collected.All cases were detected on the presence of ANA and the level of immunoglobulin,FT3,FT4,and thyroid specific antibodies.Results The presencerate of ANA and the level of IgG in patients with GD were higher than that in healthy controls [(28.28% vs 4.55%);(70.96?26.14 vs 60.41?11.01) mmol/L](P

Objective To determine whether homocysteine(Hcy)and monosodium glutamate (MSG)could lead to animal model of hypertensive disorder complicating pregnancy and its mechanism. Methods Female adult Wistar rats were randomly divided into 4 groups:pregnant control group(PN), pregnant Hcy group(PH),pregnant glutamic acid group(PG)and pregnant Hcy and glutamie acid group (PHG).The rats of each group were injected with Hey 200 mg/kg or physiological saline every day intraperitoneally and with MSG or 0.9% saline every other day via Hcy injection from the 10th day to the 20th day of pregnancy.The blood pressure,urine protein,function of liver and kidney,weight of placenta, length and weight of fetus were all measured.The histological change of the pallium and the change of behavior of pregnant rats were also observed.Results(1)The blood pressure in PH[(107?8)mm Hg, 1 mm Hg=0.133 kPa],and PHG group [(109?10)mm Hg] after the treatment increased significantly compared with those in other groups from the 12 th day after pregnancy(P

Objective To study the effect of BCL-2 ?-radiation on BCL-2 gene in dogs, and its relationship and signifcane on apoptosis of proliferated smooth muscle cells of bile duct wall. Methods The ~(103)Pd (radioactivity) stent(experiment group) or ordinary stent(control group) was positioned into the target segment of bile duct. The injured bile duct segments were dissected free from the dogs, and BCL-2 gene in the (control) and r-radiation-induced apoptotic smooth mucle cells of bile duct wall was analysed by using (immuno-histochemical) technique. The number of apoptotic cells was counted, and size of lumen of bile duct in both groups was measured by a computerized imaging system.Results BCL-2 gene expression was weaker in the ~(103)Pd radioactive stent group than in the ordinary stent group. The group of dogs with low expression of BCL-2 genes showed marked apoptosis of proliferated smooth mucle cells of bile duct and there was no overt stenosis of extrahepatic bile ducts. The group that showed high expression of BCL-2 gene did not show marked apoptosisi of proliferated smooth muscle cells of bile duct, and there was marked stenosis of extrahepatic bile duct.Conclusions The expression level of BCL-2 in experimental dogs is related to the develoment of (cellular) apoptosis and to radiation sensitivity of the cells. ~(103)Pd radioactive stent can reduce the expression of BCL-2 gene, promote apoptosis of proliferated smooth muscle cells of bile duct, and suppress stricture (formation) of extrahepatic bile duct.

Objective: To investigate the clinical effect of nursing intervention for respiratory function exercise in patients with silicosis complicated by stable chronic obstructive pulmonary disease (COPD) . Methods: A total of 60 patients with silicosis complicated by stable COPD who were hospitalized in Department of Occupational Diseases, Laigang Hospital Affiliated to Taishan Medical College, from August 2017 to April 2018 were enrolled and randomly divided into control group and observation group, with 30 patients in each group. The patients in the control group were given routine treatment and respiratory function exercise, and those in the observation group were given nursing intervention in addition to the treatment in the control group. The two groups were compared in terms of pulmonary function, blood gas parameters, and six-minute walk distance before intervention and after 2 months of intervention. Results: After intervention, the observation group had significantly higher forced expiratory volume in 1 second (FEV₁) , forced vital capacity (FVC) , arterial partial pressure of oxygen (PaO₂) , and six-minute walk distance than the control group (P<0.05) , while there were no significant differences between the two groups in FEV₁/FVC and partial pressure of carbon dioxide (P>0.05) . Conclusion Nursing intervention can effectively improve FEV₁, FVC, PaO₂, and 6-minute walking distance in patients with silicosis complicated by stable COPD.

OBJECTIVETo investigate the clinical manifestations, pathological characteristics, and treatments of urothelial-type mucinous adenocarcinoma of the prostate (UMAP).

METHODSWe reported a case of UMAP, reviewed relevant literature, and analyzed the clinicopaothological features, diagnosis, treatment, and prognosis of the disease.

RESULTSThe patient was a 60-year-old male and underwent transurethral resection of the prostate for dysuria. Postoperative pathology indicated mucinous adenocarcinoma and sigmoidoscopy revealed no primary colon cancer. Immunohistochemical staining showed the negative expressions of PSA and P504s and positive expressions of CK7, CK34 β E12, CK20, and CDX2. Thus UMAP was confirmed and treated by intensity-modulated radiotherapy. Then the patient was followed up for 30 months, which showed desirable therapeutic result, with neither local progression nor distant metastasis.

CONCLUSIONUMAP has a bad prognosis and its diagnosis depends on pathological and immunohistocchemical examinations. It responds well to radical prostatectomy but is not sensitive to endocrine therapy. Radiotherapy can be considered for those who are not fit to receive radical prostatectomy.

Objective To investigate the expressions of CD147,MMP-9 and TIMP-1 in human gliomas and analyze the correlations.Methods Expressions of CD147,MMP-9 and TIMP-1 were assessed in paraffin-embedded specimens collected from 78 gliomas and 12 benign brain lesion tissues by immunohistochemistry.Real time PCR was performed to detect CD147 mRNA expression.Results The positive rates of CD147,MMP-9 and TIMP-1 expression were 62%(48/78),71%(55/78),59%(46/78) respectively.We found a significant positive correlation between CD147,MMP-9,TIMP-1 expressions and poor gliomas differentiation by Spearman analysis(rs=0.2671-0.5631,Ps＜0.01).There was also a significant positive correlation between CD147 and MMP-9 expression(rs =0.3576,P＜0.01).In addition,the expressions of CD147(47% vs.80%,x2=9.510),MMP-9(56% vs.89%,x2=10.702),and TIMP-1(49% vs.71%,x2=4.138) were significantly higher in advanced gilomas than early gliomas(Ps＜0.05).The relative expression levels of CD147 mRNA in gliomas of Ⅰ to Ⅳ pathological grades were 0.15,0.27,0.46,0.78 respectively.Conclusion The expressions of CD147,MMP-9 and TIMP-1 were important characteristic of gliomas,which may serve as biomarkers in the glioma prognostic prediction.

Objective To investigate the different analgesic effects of acupuncture by selecting points along and not along the meridian in treating migraine, analyze the necessity of selecting points along the meridian in the treatment of migraine with acupuncture, and to provide evidence for the acupuncture treatment for migraine.Method Sixty-nine migraine patients were selected as the study subjects and randomized into Shaoyang meridian group, Yangming meridian group and a non-meridian point group by adopting a complete randomized design, 23 cases in each group, to respectively receive acupuncture at the Yuan-primary point of Foot Shaoyang Meridian Qiuxu (GB40), the Yuan-primary point of Foot Yangming Meridian Chongyang (ST42), and a non-meridian point at the midpoint between Qiuxu and Chongyang. Of the three groups, only Shaoyang meridian group selected point along the meridian. The improvements of pain intensity in the three groups were compared, and the pain intensity was measured by using Visual Analogue Scale (VAS). Nonparametric test was used to analyze whether there were significant differences in comparing the improvements of pain in the three groups.Result According to the statistical analyses, the pain intensities were improved significantly in each group (P<0.001), while there were no significant between-group differences in comparing the improvement of pain intensity (P>0.05).Conclusion In the treatment of migraine with acupuncture, selecting points along the meridian and not along the meridian (including non-meridian point) produces equivalent analgesic effect.

BACKGROUND:Epidermal growth factor is an auxiliary growth factor,but its effect on the growth of bone marrow mesenchymal stem cells (BMSCs) is uncertain.OBJECTIVE:To establish a mature method for isolation,extraction and identification of rat BMSCs,to investigate the effects of epidermal growth factor (EGF) on the proliferation and migration ability of BMSCs and to explore its potential mechanisms at the same time.METHODS:Rat BMSCs were isolated and purified using the improved whole bone marrow adherence method.After the cells were subcultured to the third generation,we detected the expression of cells surface antigens CD29,CD45 and CD90 by flow cytometry.BMSCs were further identified by osteogenic and adipogenic differentiation.Meanwhile,the effect of EGF on the proliferation of passage 3 BMSCs was measured by cell counting kit-8 and clonogenic assay.And the migration of P3 cells was verified by Transwell chamber.In addition,we detected the expression of proteins related to PI3K/Akt and nuclear factor-κB signaling pathways by western blot assay.RESULTS AND CONCLUSION:The primary BMSCs were polygonal and spindle-shaped,and then gradually appeared to be spindle-shaped.The results of flow cytometry demonstrated that the passage 3 cells were positive for CD29 and CD90,but negative for CD45.Furthermore,we successfully induced the osteogenic and adipogenic differentiation of BMSCs in vitro.Additionally,our data demonstrated that EGF promoted the proliferation and migration of passage 3 BMSCs.The relative expression levels of p-Akt and Bcl-2 of PI3K/Akt signaling pathway was up-regulated and the expression of Bax was down-regulated.At the same time,the relative expression level of phosphorylated p65 of nuclear factor-κB signaling pathway was up-regulated and the expression of phosphorylated inhibitor κB was down-regulated.Moreover,the downstream protein of matrix metalloproteinase-9 was up-regulated.Those proteins were related to the migaration of BMSCs.In summary,our results suggest that EGF could promote the proliferation and migration of BMSCs.
