Aim To analyze the antibiotic activity and mechanism of a polypyridyl ruthenium complex. Meth-ods The antibacterial activity of [ ( Phen ) 2 Ru ( dp-pz) ] ( PF6 ) 2 was determined by MIC and MBC value. Based on a fluorescent activity of this complex, the flu-orescent emission spectra was used to analyze the com-bination of complex to DNA. Then the competition combination was analyzed between complex and Gold View to DNA. Lastly, gel electrophoresis of DNA was applied to detect the combination situation between complex and DNA. Results This kind of polypyridyl ruthenium complex showed a significant antibacterial activity with a minimum antibacterial conentration of 0. 2~0. 4 g · L-1 . That was caused by the combina-tion and distortion of DNA due to the activity of this complex. Conclusion The antibacterial activity and the mechanism of antibacterial activity about [ ( Phen) 2 Ru( dppz) ] ( PF6 ) 2 are confirmed in this re-search, which provides a good foundation for the devel-opment of such class of compound.

[Summary] This article reviewed the clinical features in two diabetes cases complicated with nasal‐brain mucormycosis by pathology and pulmonary mucormycosis. In one patient with diabetes combined with pulmonary mucormycosis ,manifestations of chest pain and hemoptysis ,the right upper lung biopsy tip morphology was consistent with Mucor ,successfully cured with amphotericin and operation treatment. The other patient with diabetes‐complicated nasal mucormycosis with headache and nasal cavity clump , showed black caseous matter ,finally hemiplegia. A nasal cavity tumor was proved by pathological examination. After treatment with fluconazole and operation ,the patientdied. Mucormycosisis rare and may be secondary to diabetes and hypoimmunity disease. It needs rapid diagnosis and treatment.

Objective To explore the treatment perscription with the method of integrated traditional and western medicine in type 2 diabetes.Methods With the methods of differential diagnosis of diseases in western medicine and differential symptoms and signs in traditional Chinese medicine(TCM),the diseases were separated into different patterns of syndrome and treated with propotional prescription of TCM.The curative effect was evaluated with the scores in the integration of symptoms and the changes on the levels of blood glucose and glycated-hemoglobin.Results Clinical curative effects were achieved using the prescription of TCM and the simple western medicines.The curative effects were much better on lowering integration of symptoms and the level of pre-meal blood glucose with the prescription of TCM than those of the simple western medicine.Conclusion The clinical curative effects are significant on relieving the clinical symptoms of patients with the prescription of TCM than those of the simple western medicine.

Objective To observe auditory brainstem response evoked at different electrode positions adopting electrode slices .Methods The ABRs of 12 normal guinea pigs (24 ears)were recorded by two methods using clicks as stimulation .Active electrode was positioned at the vertex while the ground electrode at the nose .The reference e‐lectrode was placed on bilateral pinnas or mastoids .Then observe waveforms ,response thresholds (RT) ,peak la‐tencies(PL) and inter-peak latencies (IPL)of ABR .Results No significant difference were observed in the RT ,Ⅰ ,Ⅱand Ⅲ PL ,Ⅰ - Ⅲ IPL of ABR between the two methods(P>0 .05) .When stimulation was decreasing and with the reference electrode slices placed at bilateral pinnas ,waveⅡpeak was stable and discernable of ABR record‐ings across twenty -four ears of guinea pigs .The amplitude decreased more slowly than any other waves ,and dis‐appeared at the last .While reference electrode slices were placed on bilateral mastoids ,the amplitude of wave Ⅲ de‐creased more slowly than any other waves except wave Ⅳ ,and disappeared at lost .Ⅱ - Ⅲ ,Ⅲ - Ⅳ IPL became shorter .These two positions both recorded amplitude higher and PL advanced for wave Ⅳ as the stimulation de‐creased by 20 to 40 dB nHL ,and Ⅲ - Ⅳ IPL became shorter .This phenomenon was more obvious when reference electrode was placed at mastoid .Conclusion Wave Ⅱwas more stable and discernible with reference electrode placed at the bilateral pinnas .Therefore wave Ⅱ recorded by this way can be a new method to record the ABR threshold of g uinea pig s .

Objective To observe the safety and effectiveness of high-dose chemotherapy(HDT) supported by autologous peripheral blood hematopoietic stem cells transplantation(APBHSCT) in the patients of terminal or relapsed malignant tumors.Methods The patients achieved CR or PR after 4 cycles of conventional salvage chemotherapy were divided into two groups randomly.26 patients in the research group were adapted APBHSC+HDC,50 patients in the control group were adapted 2～4 cycles of routine chemotherapy.Results In the research group,hematopoiesis was reconstructed in all patients,8 out of 17 patients who achieved PR after 4 cycles of conventional salvage chemotherapy turned into CR after APBHSC+HDC(CR rate 47.1%).In the control group,33 patients who achieved PR after 4 cycles of conventional salvage chemotherapy were still PR after 2～4 cycles of routine chemotherapy.The median survival period in the research group was 11 months,which was longer than the one in the control group.The survival rates of 2,3 and 4 years in the research group were evidently higher than the ones in the control group(P

objective To observe whether the killing effect on HCC SMMC-7721 cell of the antihepatocellular carcinoma scFv reconstructed by pharmacy was enhanced or not.Methods Prokarycytic expression vector containing PET32a-RC-RNase was induced to express by IPTG.The inclusion body purified and Western-blotting was used.PC.CHOL and CHS was added in chloroform.Dry membrane was formed after chloroform was removed.RC-RNase protein solution was added to dissolute the membrane.Then pass the solution over a Sephadex G-50 column after ultrasound and filtrated to detect the encapsulation efficiency of the liposome.The solution reacted in EDC.SSNHS and MES for 30 minutes.Then add hdscFv to the solution in 4 ℃ over night.MTT method was used to detect the killing effect on HCC cell of immunoliposome RC-RNase,immunotoxin RC-RNase and liposome RC-RNase in vitro.Resuits The killing effect on HCC cell of immunoliposome RC-RNase is the best.but that of Iiposome RC-RNase is the worst.The respective JC50 are:3.28μg/ml,22.44μg/ml and 98.26μg/ml.Conclusion The anti-hepatocellular carcinoma scFv relomtructed by pharmacy can promote the killing effect on HCC cell and may have potential in the treatment of hepatocarcinoma.

Objective To explore the psychological status of patients after hand tenolysis and the pertinent nursing countermeasures. Methods 47 patients after hand tenolyais were selected and investigated their psychological status and relevant influencing factors with serf-designed questionnaire and symptom checklist-90(SCL-90). Besides, corresponding psychological nursing were applied. The SCL-90 results of Chinese Norm were adopted to undergo comparison with them and t test was chosen. Results On the first day after operation, the score of the investigation objectives was significantly different compared with that of the Chinese norm. After pertinent mental nursing, their symptoms alleviated, and no significant difference was seen between them. Conclusions There are obvious psychological obstacles in patients after hand tenolysis. The pertinent mental nursing has important effect on rehabilitation training and functional rehabilitation after hand tenolysis.

Objective Hermaphroditic planarians possess a very important position in the systematic evolutionary history of animal, as they are capacity of complete regeneration. Hence, the research on histological structure of autofluorescence has been carried out to provide a crucial insight into the developmental and regenerative biology. Methods Part of histological structure of planarian (Dugesia japonica) was revealed with HE method, Masson method and Van Gieson method. Their autofluorescence was observed with ultraviolet. There were six planarians in each stained group and the autofluorescence group. Results Epidermis, outer epidermis of pharynx, protonephridium, intestine, the photoreceptor cells and longitudinal nerve cords, all radiated blue autofluorescence. The epithelial dissociation side of copulatory bursa radiated yellow autofluorescence, its middle part radiated blue autofluorescence, its fundus side radiated weakly blue autofluorescence. Testis could hardly give off autofluorescence. Pigment cells of eyepot could not give off autofluorescence. Conclusion The research on configuration and autofluorescence of planarian eye may offer help for the study of origin and evolutionary law on eye of invertebrate.

Objective To analyze the alterative characteristics of the extravascular lung water (EVLW ) in the patients with septic shock and clarify its value on the prognosis of these patients.Methods By the methods of retrospective analysis,according to the ultimate survival,21 patients with septic shock were divided into survivor group (10 cases) and non-survivor group (11 cases).The clinical features of the patients were observed and hemodynamic monitoring was made with PiCCO monitor.The EVLW was measured and the relationship between the EVLW and the prognosis of patients was analyzed.Results On the first,second and third day,EVLW was (12.7 ±1.8),(11.3 ±1.3),(10.1 ±1.3) ml/kg in survivor group,and (14.4 ± 1.0),(14.6 ± 1.4),(14.6 ±1.3) ml/kg in non-survivor group respectively,and there were statistical differences between two groups (P <0.05).However,on the second day after the intensive therapy,EVLW in survivor group dropped significantly(P＜0.05),but the non-survivor group only declined slightly,and compared with the result of the first day,there was no obvious difference (P >0.05).Conclusions The EVLW in the patients with septic shock increases significantly.The dynamic changes of the EVLW may be one of the factors for predicting the prognosis of patients with septic shock.
