Chinese Journal of Hospital Administration 1996;0(02):-
Objective To analyze the effect of the new cooperative medical care on the use of outpatient services by rural residents so as to provide scientific basis for its improvement. Methods Using the stratified cluster sampling method, house-to-house surveys on the residents of Dongying via interviews were conducted both before and after the implementation of the new cooperative medical care. Results Although the two-week rate of seeking medical services by the rural residents after the implementation of the new cooperative medical care did not increase, changes did take place in the flow direction of the patients and the rate of seeking medical services at the end of two weeks took a downward turn. Fairness in the use of health services by the residents was enhanced. Conclusion The new cooperative medical care strongly guarantees rural patients' access to medical care.

Purpose:Our experiments are dealing with the affect of docosahexaenic acid(DHA) in doxorubicin to cytoxicity effect of MDA-MB-435s, which is of the anti-human breast cancer and whether it is one of the effect mechanisms that it via the lipid peroxidation of DHA.Methods:Add different match such as anti-cancer drugs?PUFAs?oxidan system of sodium ascorbate and ?-methy-1.4-naphoqui-none?antioxidant of Dl-?-tocopherol and so on to the culture cell line of MDA-MB-435s each 24 hours for 6 days, estimate MDA by TBA with cell extracts and estimate the contents of NO via nitrite salt spectrophotography, then draw out a dosage-effect correlation straight line among contents of MDA,NO and cytoxicity. Mitox is used as contraposition to the peroxidation of ADM which is enhanced by DHA for peroxidation of mitox is low.Results:There have been obvious changes on the contents of MDA of the lipid peroxidation has paralled increased while NO has decreased. There is recitilinear correlation relationship among the contents of MDA and NO from cell extracts and the cytoxicity.Conclusions:It is obvious that DHA can add the cytoxicity of cell line of MDA-MB-435s with ADM, particularly after add non-cytoxicity oxidant. It is lipid peroxidation of oncocyte that one of the mechanisms of DHA can enhance anti-breast cancer effect of ADM.

By means of literature review,the authors initiated the behavior expression system of hospitals' social responsibilities,which is further refined and revised with questionnaires and Delphi method.13 expressions of such behavior expressions were determined,namely “providing quality of care to patients”,“undertaking rescue assignment for emergencies”,and “fulfilling government-assigned tasks”.All of the 13 expressions were supported by 75% of the experts during the second round of experts consultation.

OBJECTIVE:To improve the related standards in China Pharmacopoeia and to enhance its operation.METH_ ODS:Issues on“general rules on preparations”,“bacteria endotoxin test”,assaying of glucose injection in China Pharmacopoeia were analyzed and discussed.RESULTS&CONCLUSION:The dosage forms recorded are limited and some varieties of preparations are hard to be classified.How long exactly the gel formed by tachypleus amebocyte lysate and bacteria endotoxins remained cemented should be regarded as positive,which should be clearly defined.In determining the optical rotation by po?larimetry,ammonia test solution should be added to the semi-products to achieve balance but not in the finished products for differentiation.

Background and purpose:The impact of the two factors of von Willnbrang factor(vWF) and integrin?3 on tumor metastasis has not been recognized. This study was done to investigate the expression of vWF and integrin?3 in human lung cancer cell line H460,the association between the two factors and tumor metastasis effect of vWF and integrin?3 on adhesion of human lung cancer cell line H460. Methods:The expression of vWF and integrin ?3 protein was examined by immunohistochemical staining. The impact of vWF and integrin?3 on adherent effect of tumor cells was evaluated by adhesion experiment, antibody inhibiting experiment and MTT.Results:Positive expression of vWF and integrin?3 was detected in H460 human lung cancer cells. H460 human lung cancer cells were able to adhere to vWF. Using anti-integrin?3, we observed that the ability of cell adhesion to vWF was inhibited,and A Value decreased from 1.59?0.06 to 0.55?0.03(P=0.01619). Using anti-vWF, we observed cell adhesion to vWF was inhibited too and A Value decreased from 1.60?0.06 to 0.54?0.03(P=0.01598),which had the same effect when using anti-integrin?3.Conclusions:H460 human lung cancer cells are capable of producing vWF, and vWF expression contributes to metastasis by adhering to cancer cells, integrin?3 is the vWF receptor on H460 human lung cancer cells.

Objective To investigate the pathogenesis,high risk factors,clinical characteristics,methods of diagnosis and treatment,and prognosis of vaginal intraepithelial neoplasia (VAIN).Methods The clinical data of thirteen cases of VAIN treated in Zhejiang Provincial Cancer Hospital dated Mar.2002 through Dec.2008 were reviewed and analyzed retrospectively.Results Twelve of 13 VAIN cases were performed the human papillomavirus(HPV) detection with 92% (11/12) HPV positive rate.None of the cases shown specific clinical manifestation.Among the 13 cases,6 of them accompanied with cervical cancer,4 cases with cervical intraepithelial neoplasia (CIN ),and 3 cases with vulvar intraepithelial neoplasma (VIN).Five cases synchronously diagnosed with cervical lesion and 3 with vulva lesion were underwent surgery,while the other 5 cases were diagnosed metachronously.Among 8 cases underwent surgery,1 case with CIN underwent argon plasma coagulation (APC) after surgery,1 case with the positive edge of VIN underwent APC.During follow up,1 case with locally advanced cervical cancer underwent radiotherapy again,3 cases with VAIN received APC,while 1 cervical cancer cases with VAIN received no treatment.The average follow-up time was 25.6 months (range 6-87 months).Two cases died of cervical cancer metastasis.The other 11 cases were normal and still alive.None of them progressed to invasive carcinoma.Conclusions The main reason of VAIN is HPV infection.There are not specific clinical manifestations,usually diagnosed when reviewing cervical or vulva lesions and rarely progressed to invasive carcinoma.The main treatment of VAIN is surgery with the adjuvant treatment of APC.

Objective To investigate the effects of positive end-expiratory pressure (PEEP) on hemodynamics and intra-abdominal pressure in patients with acute respiratory distress syndrome (ARDS) with normal intra-abdominal pressure (IAP) and intra-abdominal hypertension (IAH) during mechanical ventilation under a incremental PEEP.Methods Eighteen ARDS patients with normal IAP or IAH treated in intensive care unit of Anhui Provincial Hospital were enrolled for study.At different PEEP levels (5,10,15,20 cmH2O),hemodynamic parameters including extravascular lung water index (EVLWI),intrathoracic blood volume index (ITBVI),stroke volume variation (SVV) and IAP were measured with PICCO technology.Results Compared with ARDS patients with normal IAP,the ARDS patients with IAH were characterized by:(1) EVLWI was decreasing under the increment of PEEP,but there was no significant difference between 15 cmH2O and 20 cmH2O (t =0.593,P =0.572).As PEEP was gradually escalated,EWLVI had no significant changes in patients with normal IAP.(2) SVV increased as PEEP was being titrated to higher level in both groups but in normal IAP group such effect was observed till PEEP above 10cmH2O (PEEP5 vs.PEEP10,t=0.326,P=0.752; PEEP,10 vs.PEEP 15,t=-20.032,P< 0.01).(3) There was no statistical difference in ITBVI between two groups at varied levels of PEEP.(4) PEEP could increase IAP levels and had much more profound effects on patients with IAH.Conclusions PEEP is a contributing factor changing IAP.It is necessary to take the level of PEEP into account as IAP variation is interpreted in patients under mechanical ventilation.Different PEEP levels can significantly affect the EVLWI in patients with IAH but not do not in ones with nomal IAP.
