OBJECTIVETo observe the efficacy difference in the treatment of breast hyperplasia between the combined therapy of auricular point sticking and Xiaopijian and the simple application of Xiaopijian.

METHODSNinety-one patients were randomized into an observation group (46 cases) and a control group (45 cases). In the observation group, the sticking therapy on the auricular points was applied in combination with the oral medication of Chinese herbal medicine, Xiaopijian. Auricular points included Ruxian, Neifenmi (CO18), Luanchan, Shenmen (TF4), Gan (CO2), Pi (CO13). The auricular point sticking therapy was applied once a week on the auricular points of one side alternatively. Xiaopijian was the self-prepared decoction. The main ingredients are radix bupleuri Bupleurum chinense, spica prunellae prunella vulgaris and radix peoniae alba Paeonia lactiflora, 30 mL each time, three times a day. In the control group, Xiaopijian was simply prescribed for oral administration, 30 mL each time, 3 times a day. The treatment was discontinued during menstruation in the two groups. The menstrual cycle of one month made one session of treatment. The treatments for 3 sessions were observed. The scores of symptoms and physical signs, including the degree of breast pain, hardness and size of breast masses as well as the scores of general and supplementary symptoms were compared before and after treatment in the patients of the two groups. The clinical efficacy was compared between the two groups.

RESULTSAfter treatment, the scores of symptoms and physical signs were reduced apparently as compared with those before treatment in the patients of the two groups (both P<0. 05). The score reduction in the observation group was much more than that in the control group (11.02±1. 78 vs 9.82±1. 53, P<0. 05). The total effective rate was 95.7% (44/46) in the observation group, higher apparently than 80. 0% (36/45, P<0. 05).

CONCLUSIONThe combined therapy of auricular point sticking and Xiaopijian achieves the superior efficacy on breast hyperplasia as compared with the simple application of Xiaopijian.

Objective To investigate the resistance of multi-drug resistant Acinetobacter baumannii against aminoglycosides and its resistance genes.Methods The minimal inhibitory concentrations (MICs) of seven antimicrobials (gentamicin, amikacin, tobramycine, netilmicin, neomycin, streptomycin and kanamycin) against 20 strains of multi-drug resistant Acinetobacter baumannii were detected by agar dilution method. Meanwhile, two resistance genes of aminoglycoside nucleotidyltransferase were amplified by PCR and vertified by DNA sequencer.Results It was found that MIC50 and MIC90 of gentamicin, amikacin, streptomycin and kanamycin in 20 strains of Acinetobacter baumannii were all above 1 024 mg/L, and their resistant rates were 95%, 95%, 100% and 90% respectively, while the resistant rates of tobramycin, netilmicin and neomycin were 85%, 90% and 40% respectively. Two aminoglycoside-modification genes ant(2″)-Ⅰ and ant(3″)-Ⅰ were detected in 20 strains, with 55% and 80% of positive rate respectively. The double positive rate of two resistance genes was 50%.Conclusion The resistance of multi-drug resistant Acinetobacter baumannii against aminoglycosides was closely associated with ant(2″)-Ⅰ and ant(3″)-Ⅰ genes.

Objective To observe the antitumor effect of 153Sm-DTPA-c (CGRRAGGSC) on MHCC97-H human liver cancer using a nude mice model.Methods 153Sm-DTPA-c(CGRRAGGSC) was indirectly synthesized by the reaction of 153SmC13 with DTPA-c(CGRRAGGSC).Western blot was used to detect the expression changes of IL-11 receptor of eight different cell lines.20 MHCC97-H tumor-bearing nude mice were randomly divided into four groups by random number table method with five mice in each group,administered with different activities of 153 Sm-DTPA-c (CGRRAGGSC) by tail vein injection (5.5,11.0,22.0 MBq/0.2 ml and physiological saline/0.2 ml in turn).All nude mice were terminated after 16 d then the tumor tissue was observed and analyzed with microscopy,electron microscopy and immunohistochemistry for Ki-67,Bc1-2 and IL-11 receptor.Western blot was used to evaluate the expression changes on IL-11 receptor of tumor tissue at different doses.Results After administration with 153 Sm-DTPA-c(CGRRAGGSC),the central region in the early stage of tumor became dry,necrosis,and crusting.In the late stage,tumor continually grew surrounding necrosis tissue.The inhibition rates in the low,middle and higher dose group were (22.72 ±2.76)％,(34.65 ±2.36)％ and (85.13 ±5.78)％,respectively(F =89.32,P ＜ 0.05).The morphologic results showed that tumor structures were severely damaged along with radiation dose.The results of immunohistochemistry showed that the IL-11 receptor-positive cells in the control group and 5.5 MBq group was (84.13 ± 5.71) ％ and (61.57 ± 5.98) ％ (t =13.62,P ＜0.05),respectively.The Ki-67 and Bcl-2 positive cells were decreased in the injection group (t =20.91,6.68,P ＜0.05).Western blot analysis showed that the expression of IL-11 receptor protein decreased with antitumor-effect of radiation.Conclusions 153Sm-DTPA-c (CGRRAGGSC) effectively depresses the growth of MHCC97-H human liver cancer and suppresses the expression of IL-11 receptor,and hence could be a promoting agent for the treatment of MHCC97-H human liver cancer.

Objective To analyze the changes and characteristics of cancer incidence and mortality among Jiaxing residents in the past 6 years,and to provide evidence for the prevention and control of cancer incidence and mortality.Methods Registered malignant tumor data from the Zhejiang Chronic Disease Information Monitoring and Management System were collected and analyzed based on the International Statistical Classification of Diseases (ICD-10).The statistical indexes used for analyses included crude incidence,standardized incidence,crude ortality,standardized mortality,potential years of life lost (PYLL),average years of life lost (AYLL),rate of potential years of life (PYLL‰) and so on.Results From 2010 to 2015,the crude incidence,the standardized incidence,the crude mortality,and the standardized mortality were 342.52/105,240.89/105,194.71/105 and 126.27/105,respectively.The crude incidence and mortality for males were both higher than those for females(378.44/105 vs.307.49/105,x2=763.06,P＜0.01;255.31/105vs.135.62/105,x2-3 814.11,P＜0.01).The PYLL,AYLL and PYLL‰ of residents in Jiaxing were 248,307 years,6.16 years and 12.00‰,respectively.The PYLL‰for males was significantly higher than that for females(x2=37073.85,P＜0.01).The AYLL for females was 6.50 years,higher than that for males(5.98 years)(t =125.15,P＜0.01).The incidence of malignant tumors increased with age,especially in the older than 40 age group,with the older than 80 age group showing the highest rate at 1 779.01/105 (x2 =38 840 907,P ＜ 0.01).Rates for Lung cancer (70.59/105),colorectal cancer (39.86/105),liver cancer (29.14/105),breast cancer(26.73/105) and stomach cancer (26.00/105) were the most common malignant tumors in Jiaxing.Conclusions The morbidity and mortality of malignant tumors are showing signs of rising and the incidences of lung cancer and gastrointestinal cancer are particularly pronounced in Jiaxing.In consequence,measures for the prevention and control of malignant tumors should be developed with clearly defined objectives and research on the pathogenesis of malignant tumors should be stepped upto reduce the incidence and mortality of malignant tumors.

Objective To study the effect of laparoscopic cholecystectomy(LC) in the treatment of patients with schistosomiasis hepatic cirrhosis(SHC) complicated with symptomatic gallstone. Methods The clinical data of 256 cases of SHC with symptomatic gallstone underwent cholecystectomy in recent 4 years in our hospital were reviewed retrospectively. Of them, 74 underwent LC , which was compared with the cases who underwent open cholecystectomy(OC) in operation time, operative heamorrage,operative complications, and hospital stay.Results The operation time in LC group and OC group was 63 min and 54 min respectively; the operative bleeding of LC group was 15.6ml, OC group 85 ml;and hospital stay was 1.2days in LC group,8.9 days in OC group。Six cases of LC group was converted to OC.None had postoperative complications in LC group; but 1 case in OC group had bile leakage. Conclusions With strict the operative indications and proper operative method,LC in the treatment of SHC patients with gallstone is safe and feasible.

Objective To investigate the inhibitory effects of RNA interference on expression of matrix metalloproteinase-2(MMP-2)gene and invasiveness of human pancreatic cancer cell line PANC-1 in vitro.Methods Small interference RNA targeting MMP-2 gene was designed and constructed to plasmid pGCsi-U6.Recombinant plasmids were transfected to pancreatic carcinoma PANC1 cells with Lipofectamine 2000.The efficiency of transfection was evaluated by flow cytometry.RQPCR was used to detect the expression of MMP-2 mRNA.The expression of MMP-2 protein was determined by ELISA.The invasiveness of PANC-1 cells was measured by transwell chamber experiment.MTT assay was used to detect the proliferation and growth of PANC-1 cells.Results Sequencing confirmed that the MMP-2 siRNA plasmid was successfully constructed.The best efficiency of transfecting recombinant plasmid was 82.1%.After transfection of the MMP-2 siRNA plasmid, the MMP-2 gene expression of PANC-1 cells was suppressed to 71.74 %(P＜0.05),and protein expression of MMP-2 fell to 49.82%(P＜0.05).The corresponding inhibition ratio of invasiveness was 33.0%(P＜0.05).There was no marked difference in proliferation rate measured by MTT assay among different groups(P＞0.05).Conclusions RNAi targeting MMP-2 can suppress invasiveness of PANC-1 cells in vitro.This suggests that MMP-2 could be a target for gene therapy of pancreatic carcinoma.RNAi is expected to open up a new prospect for tumor therapy.

AIM: To evaluate the effect and safety of Rhodamine 123 (Rh123)-mediated photodynamic treatment (PDT) on acute graft versus host disease. METHODS: An acute graft versus host disease (aGVHD) mice model was established using C57B/6 mice as donors and BALB/c mice as recipients. Mixed lymphocytic cells were cultured with Rh123 (50 nmol/L) and irradiated by argon laser 30 mW/cm2 for 3 min, then transplanted to BALB/c recipient mice mixed with donor bone marrow. Hepatopoietic recovery, aGVHD occurrence, survival time after transplantation and pathological changes were observed. In addition, CD3+CD69+ positive rates of MLC were examined by flowcytometry. RESULTS: Occurrence of aGVHD decreased, degree of pathological manifestation became milder, survival rates were higher than non PDT groups. CD3+CD69+ rates of MLC cells treated with photodynamic therapy (PDT) and cultured for 24 h significantly decreased. CONCLUSION: Rh123-mediated PDT can effectively prevent aGVHD of allogeneic bone marrow transplantation in mice.
