ObjectiveTo explore the effects of nutritional intervention and individualized nursing on nutritional risk, undernutrition and quality of life (QOL) in end-stage renal disease (ESRD) patients with peritoneal dialysis. MethodsA total of 104 ESRD patients with peritoneal dialysis who met the inclusion criteria of the protocol were enrolled and randomized to receive nutritional intervention plus individualized nursing ( study group, n =52 analyzed) or self-diet plus routine nursing ( control group, n =50 analyzed) for 6 months. Nutritional risk, anthropometry, and QOL of the two groups were analyzed pre- and post-nutritional intervention. ResultsBaseline data were comparable in the two groups. Prevalences of nutritional risk and undernutrition in study group were significant lower than those in control group after the intervention ( nutritional risk: 32.6％ vs. 56.0％, P =0.028 ;undernutrition: 15.4％ vs. 34.0％, P =0.038). The decrease of grip strength in study group between pre- and post-study was significantly less than that in control group [( - 1.6 ± 0.9 ) kg vs. ( - 9.9 ± 1.4 ) kg, P =0.001], but there were no significant differences in other parameters related to anthropometry, including triceps skin-fold thickness, upper arm circumference, and arm muscle circumference ( all P ＞ 0.05 ). The QOL score significantly increased in study group after intervention but decreased in control group. The differences of renal disease and dialysis-related scores ( △KDTA: 2.5 ± 4.4 vs.- 7.9 ± 7.4, P =0.001 ) and general condition scores (△SF-36 : 3.4 ±4.1 vs.- 6.8 ± 6.3, P =0.001 ) before and after intervention were significantly different between two groups. ConclusionNutrition intervention and individualized nursing may help to improve the nutritional status and QOL in ESRD patients with peritoneal dialysis.

Objective To evaluate the current sanitary situation of the rural household latrine and the effects of decontamination of the feces in some epidemic areas of schistosome in Hubei province.Methods Six villages(4 villages with the sanitary latrines,2 villages with the non-sanitary latrines) were chosen for the investigation and 30 latrines were selected randomly in each village in September of 2007.The structure of the latrine and the situation of the faecal treatment were investigated by questionnaires.At the same time,the feces samples were collected and detected according to the related sanitary standards.Results The rate of the sanitary latrines without maggots,pupas and flies was 95%,while the rate of the non-sanitary latrines with the same situation was 33.33%.After non-hazardous treatment in the three-case-cesspool and the firedamp latrines,the qualified rates of the roundworm eggs were 95.6% and 98.6% respectively;the qualified rates of fecal coliform were both 100%;no schistosome eggs,the alive schistosome eggs and the alive roundworm eggs were detected.The morbidity rate of schistosomiasis of the villages with the sanitary latrines was 43.7%,lower than those with the non-sanitary latrines.Conclusion The faecal treatment of the rural household latrine in epidemic areas of schistosome can improve the sanitation and kill the pathogens in faeces effectively,and also can decrease the morbidity rate of schistosomiasis obviously.

Objectives:To evaluate the effect of different teeth arrangement methods on the masticatory efficiency of complete dentures.Methods: Three complete dentures for each of ten edentulous patients were made respectively by using maxillary teeth arrangement,mandibular teeth arrangement and comprehensive teeth arrangement methods.After three months of wearing,the masticatory efficiency of the three complete dentures was tested by light absorption method,and was compared to that of dentulous subjects.Results:The masticatory stroke and masticatory efficiency in denture wearing group were fewer and weaker than those in dentulous group in either bilateral mastication or unilateral mastication. Good masticatory efficiency was gained after three months of wearing the complete dentures made by the three different teeth arrangement methods.There were no significant difference in the masticatory stroke and masticatory efficiency of complete dentures made by mandibular teeth arrangement and comprehensive teeth arrangement methods,but they were both higher than those made by maxillary teeth arrangement method.Conclusions:The complete dentures made by mandibular teeth arrangement method and comprehensive teeth arrangement method are feasible for restoration of masticatory efficiency of endentulous patients.

Objective To investigate the expression level of RECK-mRNA and MMP-9-mRNA in breast cancer(BC) and fibroadenoma tissues and its significance.Methods The mRNA level of tissues of 39 cases of breast cancer and 14 cases of fibroadenoma was measured by RT-PCR technique and its correlation was analyzed.Results The mRNA level of RECK gene in breast cancer tissues was markedly lower than that in fibroadenoma tissues,while the MMP-9 level was higher in BC tissues.Conclusions RECK is a tumor suppressor gene, the expression in benign and malignant breast tissues is a negative relationship.BECK can inhibit the expression of MMP-9 and thus,inhibit the growth and metastasis of breast cancer.

Objective To investigate the effects of propofol on the spontaneous transient outward K+ currents in mouse cerebral arterial smooth muscle cells.Methods Kunming mice of both sexes,weighing 18-22 g,were used in this study.Vascular smooth muscle cells were freshly isolated from cerebral arteries in two steps.Five cells were chosen and studied.When holding potential was - 30 mV,spontaneous transient outward K+ currents were recorded before and after the application of 56 μmol/L propofol by perforated whole-cell patch-clamp technique.The amplitude,frequency,area under the curve and half time width of spontaneous transient outward K+ currents were analyzed.Results Propofol 56 μmol/L significantly increased the amplitude,frequency and area under the curve of spontaneous transient outward K+ currents.There was no significant change in the half time width of spontaneous transient outward K+ currents after administration,Conclusion Propofol can activate spontaneous transient outward K+ currents in mouse cerebral arterial smooth muscle cells,and thus induces vascular smooth muscle relaxation.

Objective Porphyromonas gingivalis(Pg)is one of the main putative pathogens of periodontal disease,espcially of adult periodontitis. This in vitro study was aimed at observing the inhibition actions of 3 kinds of antimicrobial drugs on Pg. Methods 106 stains of Pg were isolated from subgingival plaques with adult periodontitis. The agar diffusion test was used to detect the inhibition actions of metronidazole,clindamycin and tinidazole on 106 stains of Pg. Results Their MIC was respectively:0. 25mg/L,0. 6rng/L. The MIC90 of tinidazole＜MIC90 of clindamycin. The results showed:all of metroidazole, tinidazole and clindamycin can be used effectively against Pg,clindarnycin and tinidazole showed more potent antibacterial activity than metronidazole. The different concentration of Pg-liquid (l05 CFU/ml, 106 CFU/ml and 108 CFU/ml) had not influenced the results. Couclusion This study is significant to antibiotical therapy of periodontal diseases.

Objective To investigate the effect of employing achievement management in nursing management of urology department.Method The results of assessments were linked to the achievements by regulating achievement-oriented distribution and assessment methods.Results The degree in patients' satisfaction with nursing service and the score on nursing quality assessment were both significantly improved compared to pre-performance of achievement-oriented distribution and assessment(P<0.01). Conclusion The achievement-oriented management may be effective in mobilizing nurses' working enthusiasm and increase quality of care,which guarantees fundamental nursing care.

Objective To investigate the protective effect of Danxiong Recipe (DR) on brain in hypoxia mice.Methods Sixty mice were equally randomized to 6 groups:normal group,model group,propranolol group and low-,model- anti high-dose DR groups.Except the normal group,the mice in other groups were given the corresponding drug intra- gastrically according to the experimental design,once a day,for 7 days.After treatment,the survival time under nor- mobaric hypoxia condition in different groups was calculated.Meanwhile,the activities of superoxide dismutase(SOD) and nitric oxide synthase (NOS),and the contents of malondiadehyde (MDA) and lactic acid (LD) in the brain ho- mogenate were detected with test kit.Results The results showed that DR could prolong the survival time of the mice, inhibit obviously the abnormal increase of MDA and LD,reduce NOS activity,and enhance SOD activity in mice brain. Conclusion DR exerts protective effect on brain in hypoxia mice under normal pressure.

Objective To investigate the therapeutic effect of kansui root on patients with severe acute pancreatitis(SAP). Methods Clinical data of 54 cases of severe acute pancreatitis treated with kansui root(kansui root group) were analyzed and compared with 54 cases of severe acute pancreatitis treated without kansui root (control group).Results The releivng time of abdominal pain was significantly shorter than that in control group( P

0.05). The expression of VEGF121 mRNA and VEGF165mRNA in BC with lymph node metastasis was significantly higher than that in BC without lymph node metastasis(P=0.033,0.004).Conclusions The expression of VEGF121 mRNA and VEGF165mRNA in BC tissues is upregulated, and VEGF121mRNA is likely to play the major role. A high level expression of VEGF mRNA in BC patient indicates the likelihood of lymph node metastasis.
