Objective To observe the clinical efficacy of acupuncture at Guangming (GB37) and Diwuhui (GB42) in treating dry eye due to different syndromes. Method Thirty-nine dry eye patients (78 eyes) conforming to syndrome of up-flaming liver fire or liver-kidney yin deficiency were randomized into a distant group and a periocular group, to receive acupuncture at distant acupoints [Guangming (GB37) and Diwuhui (GB42)] and periocular acupoints [Cuanzhu (BL2), Tongziliao (GB1), and Taiyang (EX-HN5)], respectively. Result In the distant group, the total effective rate was 60.0% after 2-week acupuncture and 75.0% after 4-week acupuncture; in the periocular group, the total effective rate was 53.6% after 2-week acupuncture and 65.8% after 4-week acupuncture. There were no significant differences between the two groups (P>0.05). The tear production and tear film break-up time (BUT) were significantly improved in both groups after the intervention (P<0.05). The inter-group difference in the improvement of up-flaming liver fire syndrome score was statistically insignificant (P>0.05), while the inter-group difference in the improvement of liver-kidney yin deficiency syndrome score was statistically significant (P<0.05). Conclusion Acupuncture at Guangming and Diwuhui can boost the improvement of dry eye symptoms and tear production, and prolong BUT; dry eye due to up-flaming liver fire achieved a satisfactory therapeutic efficacy in both groups, while liver-kidney yin deficiency type responded better to acupuncture at distant acupoints.

Obesity,hypertension,and diabetes mellitus are main risk factors of endometrial cancer.The basis of metabolic syndrome is insulin resistance and hyperinsulinemia. Insulin resistance may contribute to an increased risk for endometrial cancer according to worldwide researches.

Primenopausal period syndrome is a kind of usual disease,and people's views differ in disease location,pathogenesis and treatment.We approach the disease from theory to expound that its disease location is Chong Channel and Ren Channel.We find that the imbalance of yin-yang,because of the deficiency in Chong Channnel and Ren Channel,is the source.We apply Chong Channel and Ren Channel,and we also harmonize yin-yang to cure the disease.

Objective:To analyze a novel antigenic determinant of Homo sapiens CMTM1-v17 protein and prepare polyclonal antibody.Methods:By means of DNA recombination method, the C-terminal(The coding sequences of 118-149 residues) of CMTM1-v17 gene was inserted into pGEX-4T-2 vector. The recombinant plasmid was transformed into E.coli XL-1 Blue to express the fusion protein of GST/CMTM1-v17. The GST tag of the purified fusion protein was removed by enzymatic cleavage with thrombin. The polyclonal anti-CMTM1-v17 antibody were prepared by immunizing rabbits with the purified protein. Highly-specific, polyclonal anti-CMTM1-v17 antibodies was purified by affinity chromatographic column matrix coupled with antigen. The specificity of the anti-CMTM1-v17 antibody was identified by Western blot and immunohistochemistry.Results:The polyclonal antibody showed specific response to CMTM1-v17 by Western blot analysis and immunohistochemistry. These results suggested that the polyclonal antibody can be used for further studies of CMTM1-v17 function.Conclusion:A polyclonal anti-CMTM1-v17 antibody has been synthesized successfully.

Objective To study clinicopathological characteristics of hereditary nonpolyposis colorectal carcinoma(HNPCC)-associated endometrial carcinoma(EC).Methods Totally 421 EC patients admitted to General Hospital of Tianjin Medical University from 1981 to 2006 were divided into three groups:group A:sporadic EC;group B:familial aggregation of EC;group C:HNPCC-associated EC.Results HNPCC-associated EC accounted for 6.4%(27/421).Mean age at time of diagnosis was 49.7years in group C,earlier than 56.3 years in group A(P=0.004)and 55.2 years in group B(P=0.035).There were 33.3%(9/27)patients with multiple primary carcinomas in group C.It was higher than 14.3%(9/63)in group B and 5.1%(17/331)in group A respectively(P=0.038,P＜0.01).There was no difference among the three groups in histological type or menopausal status(P＞0.05).The numbers of patients with low grade EC in group C(70.4%,19/27)and group B(61.3%,38/62)were more than that in Group A(P=0.013,P=0.023).Prognosis for group C was better than that in group A(P=0.021),and 5-and 10-year survival rate in groups A,B and C was 80%,70%;88%,85%;and 96%,96%respectively.Conclusions Mean age at time of diagnosis is earlier in HNPCC-associated EC than that in sporadic EC;patients with HNPCC-associated EC are more frequently complicated with multiple primary carcinomas and of low grade;prognosis is better.

Purpose To explore the expression and significance of histone methyltransferase EZH2,clinicopathological features in primary testicular diffuse large B-cell lymphoma (DLBCL).Methods Immunohistochemical of Ventana Ultra View two-step staining was used to detect expression of EZH2 in 17 cases of primary testicular DLBCL.The relationship between EZH2 expression and its clinicopathological features were analyzed.Sanger squencing was used to detect EZH2 Y641 mutation in these cases.Results Morphologically,the tumor cells resembled centroblasts in 11 cases,immunoblasts in 3 cases,and anaplastic variants in 3 cases.Immunophenotypically,14 cases were non-germinal centre B cell like (non-GCB) type and 3 cases were germinal centre B cell like (GCB) subtype.EZH2 overexpressed in all 17 cases.EZH2 overexpressed in nearly tumor celts with uniformly strong intensity in 15 cases,and more than 70％ tumor cells with moderate to strong intensity in 2 cases.The follow-up information was obtained in 9 patients,with a median survival time of 35 months.No association was found between the level of EZH2 expression and outcome of patients.No mutation of EZH2 Y641 was detected.Conclusion Primary testicular DLBCL is a rare aggressive B cell lymphoma with distinctive clinicopathological features.Detection of EZH2 expected to assist in the diagnosis and treatment of tumor.

Objective Astrgaloside Ⅳ derivative (ASId) is one of Astragaloside Ⅳ (ASI) derivatives with higher water-solubility and may have more druggability than ASI. The present study aims at observing the effects of ASId on cardiovascular parameters in chronic heart failure in rats. Methods Using echocardiographic and haemodynamic measurements, the effects of ASId on congestive heart failure (CHF) induced by ligation of the left coronary artery in rats were investigated.ventricle (LV) pressure (dp/dt) in ASId treated groups were significantly increased. Both LV volumes in diastole and in systole were decreased significantly after ASId treatment, accompanied with a trend towards normalization of relative stress. ASId treatment also inhibited compensatory hypertrophy of depressed heart. Conclusion ASId could improve cardiac functions and inhibite compensatory hypertrophy and LV remodelling, which suggests the possibility of ASId as a new therapeutic drug for the treatment of CHF.

Objective: To develop a reporter gene system based on transient transfections with a NF-?B responsive reporter gene to detect the bioactivity of IL-1? and IL-1 receptor antagonist.Methods: NF-?B reporter and Dual-Luciferase assays were applied to measure the bioactivity of IL-1? and IL-1 receptor antagonist in mouse EL4 cells(some subclones of EL4 cells expressed high level of IL-1 receptor on cell surface).pNF-?B-luc and pRL-TK, used as an internal control,were co-transfected into EL4 cells and then the IL-1? was added.Results: The results indicated that IL-1? was able to induce the expression of this luciferase,which could be blocked by IL-1 receptor antagonist. The optimal dose of IL-1? was 5(?g/L) in Dual-Luciferase assay,whose bioactivity can be effectively inhibited by IL-1ra at 50 ?g/L.Conclusion: We have established a new method to detect the bioactivity of IL-1? and IL-1 receptor antagonist,which can give repeatable results.

Objective To establish and optimize the technology and method of producing large quantity and high-paclitaxe yield callus of 〖WTBX〗Taxus chinensis var. mairei. Methods Wild maternal tree grown in Lingchuan County of Shanxi Province and cultivated tree grown in Xi′an were used as explant source. And the optimum maternal tree for explant cutting, optimum explant type, basic medium, composition and concentration of growth regulators in medium and so on, which were factors of affecting on callus induction, growth and paclitaxe yield, were examined in a series order. Results The juvenile stem segments were the optimum explants because of their earlier and higher rate callus induction than that of other explants. Medium Y5: MS+2,4-D 4.0 mg/L+KIN 1.0 mg/L or medium B5 Ⅲ: B5+2,4-D 3.0 mg/L+KIN 0.1 mg/L+Phe 0.1 mol/L was confirmed optimum callus induction medium in which callus induction rate had reached to 100%. In callus subculture medium, lower concentration of 2,4-D (0.5—3 mg/L) always increased callus growth, but higher concentration of 2,4-D (8 mg/L) reduced callus growth. When 2,4-D concentration was suitable, callus grown on B5 medium displayed lighter browning and faster tissue growth than that on MS medium. Further more, HPLC analysis confirmed that the paclitaxel yield in callus grown on medium MSⅢ was highest and had reached 0.004% of callus dry weight. In a general condition, the level of paclitaxel in calli derived from juvenile stems of wild maternal tree was higher than that in calli initiated from cultivated maternal tree's juvenile stems. Conclusion The optimization sequence of obtaining a large quantity and high-paclitaxe yield callus of T. chinensis var. mairei are dividing juvenile stem segments from wild maternal tree in May and culturing on medium Y5 or B5 Ⅲ for callus induction. After the calli having been subcultured on the same medium for 8—10 generations, one or two generations are recultured on medium MSⅢ. Finally, the calli with more paclitaxel are obtained by extracting paclitaxel out of it.

To analyze and summarize the clinicopathological features of renal inflammatory lesions which were easily misdiagnosed as renal tumors.Methods The cases from March 2006 to August 2015 in the Department of Pathology at Xijing Hospital were analyzed,retrospectively.Due to the diagnosis made by clinicians that these were renal (including renal pelvic) tumors,all cases had undergone radical nephrectomy or tumor enucleation.Among them,several inflammatory lesions were confirmed,and were combined with the patients' clinicopathological data and literature review to investigate the diagnosis and differential diagnosis.Results Of the 1 195 cases,only 6 cases (less than 1％) were renal inflammatory lesions,named as xanthogranulomatous pyelonephritis (2 cases),renal malakoplakia (1 case),renal tuberculosis (1 case),IgG4-related tubulointerstitial nephritis (1 case),and renal Wegener's granulomatosis (1 case).These diseases occurred in two males and four females (aged 14 to 55 years).All patients underwent radical nephrectomy due to the detected unilateral solitary renal mass in the imaging examination.Conclusion Renal inflammatory lesions are very rare,which show masses that are easily misdiagnosed as neoplastic lesions.Some of them have similar histological features.As the differences of treatment,a sufficient understanding of the clinicopathological features of these diseases is important to make a correct diagnosis.
