Objective To determine the resistance reversion of mitomycin (MMC) by 3′-Keto-bmt 1-val 2-cyclosporin (SDZ PSC 833) in human cervical cancer in vitro and in vivo. Metheds A xenografted mitomycin resistant mice model of cervical cancer was devolped. The reversion of mitomycin resistance by SDZ PSC 833 (1 or 3 mg/L) was detected from human cervical cancer cell (Hela) and its resistant subline Hela/MMC in vitro and in vivo. Studies in vitro include drug resistance reversion experiment and the changes of morphology. Studies in vivo including tumor volume and tumor related histopathological changes in the autopsied specimen were evaluated by comparing random sections of each group. Results Nontoxic doses of SDZ PSC 833 could result in almost partial reversion of MMC-resistance of Hela/MMC.In vivo studies also showed SDZ PSC 833 augmented the growth inhibitory effect of mitomycin on Hela/MMC xenografted in nude mice. Conclusion SDZ PSC 833 can overcome mitomycin resistance of Hela/MMC in vitro and in vivo ,so SDZ PSC 833 will be a better candidate clinically for reversing multidrug resistance.

Objective To provide basis for clinical teaching methods and course system,this article analyzed practice nursing students self-directed learning readiness status and its influencing factors.Methods The report surveyed a total of 240 nursing students in Zhengzhou University,the Peking Union Medical College by using the general information questionnaire,the Chinese version of Nursing SelfDirected Learning Readiness Scale and The Questionnaire of Clinical Teaching.The total score of the practice nursing students' self-directed learning readiness was obtained on the basis of quantitative analysis,and in this paper,the development and research status had been summarized through document analysis.Results The total score of the practice nursing students' self-directed learning readiness was (116.59±21.79) scores.The influencing factors of practice nursing students' self-directed learning readiness included:whether the students like nursing major,whether perception learning difficulties,whether having the experience of group learning,and the satisfaction to clinical teachers,curriculum system optimization.Conclusions Currently practice nursing students self-learning readiness is relatively low and have many influencing factors.A targeted training should be taken during the clinical teaching and the course system should be optimized to improve the practice nursing students' self-directed learning readiness.

Objective To approach Professor Zhu Guangli's regular pattern of differentiation of symptoms and signs in patients with hypertension accompanied by complications and in accord with the individual manifestations to add or subtract the ingredients in the prescription.Methods The patients with essential hypertension selected were those who the first time came to the Affiliated Guangxing Hospital of Zhejiang Chinese Medical University or Hangzhou Hospital of Traditional Chinese Medicine (TCM) of Zhejiang Province from September 2012 to January 2015, and were continuously followed up in the hospitals having their clinical data comprehensive. The complications, combination diseases and symptoms of hypertension were conducted as dependent variables, while the applied Chinese medicines were acted as independent variables. QUEST algorithms were employed to analyze the different dependent variables to evaluate the importance contribution rate (ICR) of every kind of Chinese medicine.Results There were 9 types of complications or combination diseases [including hyperlipemia, coronary heart disease, cardiac arrhythmia, hyperglycemia, trace albuminuria, lacunar cerebral infarction, elevation of creatinine in blood (azotemia), liver dysfunction and cardiac dysfunction] and 39 types of symptoms obtained (including dizziness, palpitation, chest oppression, insomnia, lack of strength, soreness of the waist and knees, dry mouth, loose stool, fatigue, apontaneous sweating, headache, shortness of breath, coprostasis, fullness in the stomach, blurred vision, limb numbness, low spirit, chest pain, poor appetite, abdominal distension, excessive dreaming, tinnitus, flush of the face, neck rigidity, hectic fever, bitterness in the mouth, cough, ructus, nocturia, fremitus, stenagma, pharyngalgia, heaviness in head, nocturnal sweating, frequent urination, coughing of sputum, chillness and cold limbs, aphthous stomatitis and sialosis) being the QUEST decision models. All kinds of the TCM employed in all the patients paying visits for 755 times were summed up, and the individual drug frequency of presentation in the prescription was recorded. In the study, 171 sorts of TCM and 10 620 of cumulative frequency (freq.) were involved in 755 prescriptions. The average sorts of TCM was 14.07±1.53 per prescription. The top ten kinds of TCM the most commonly used (freq.) were as follows: tuckahoe (588), Chinese yam (551), wolfberry fruit (496), white peony root (442), abalone shell (405), gastrodia tuber (395), lilyturf root (325), Huai wheat (293), curcuma root (281), rush pith (277), accounting for 38.16% in the total frequency. There were 33 kinds of TCM with frequency > 100, accounting for 74.65% in the total frequency. By the analyses of QUEST algorithms directing to the complications and combination diseases to add or subtract the items of TCM, it was discovered that the drugs with ICR > 5% were as follows: in lacunar cerebral infarction, the drug application frequencies or ICRs of batryticated silkworm and bitter cardamom were 32.69% and 50.74% respectively; in coronary heart disease, the ICRs of pseudostellaria root, astragalus root, white sandal wood and lepidium seed were 23.05%, 17.70%, 15.31% and 5.06% respectively; in cardiac arrhythmia, the ICRs of astragalus root, flavescent sophora root, Huai wheat and dragon tooth and dragon bone were 46.65%, 11.56%, 7.56%, 7.13% and 6.28% respectively; in cardiac dysfunction, the ICRs of lepidium seed and white hyaciath bean were 92.97% and 7.03%; in hyperlipemia, the ICRs of cassia seed, white sandal wood, dried rehmannia root and sargentgloryvine stem were 24.26%, 12.47%, 10.51% and 5.81% respectively; in hyperglycemia, the ICRs of trichosanthes root and dried hawthorn fruit were 51.02% and 30.18%; in trace albuminuria, the ICR of snow in June herb was 83.33%; in elevation of creatinine in blood, the ICRs of Chinese actinidia root, herb of snow in June, glossy privet fruit and centella were 81.37%, 6.21%, 6.21% and 6.21% respectively; in liver dysfunction, the ICRs of coral ardisia root, purse grass and herb of stringy stonecrop were 86.37%, 6.82% and 6.82% respectively. When the symptoms were used as the dependent variables, for the top 3 commonly seen symptoms, in the prescription, the items of TCM used with ICR > 5% were as follows: in cases with elevation of blood pressure, parasitic loranthus (ICR 89.59%) was used; with dizziness, gastrodia tuber (ICR 46.96%) and/or abalone shell (ICR 33.61%) were added; headache, rhizome of Chinese ligusticum and/or rhizome of Sichuan lovage and/or large gentian with ICR at 85.77%, 7.11% and 7.11% respectively. Conclusion Professor Zhu's essential thought in differentiation of disease and expectant treatment of hypertension in accord with the individual manifestations to add and subtract drugs in TCM is under the guidance of TCM principle of differentiation of symptoms and signs for treatment, and based on the classical theories in TCM, the reliable drugs whose actions are demonstrated clinically and experimentally are preferentially selected.

Objective To investigate the influence of the PBSC collection yield by choosing the differ-era venous accesses in the healthy donors. Methods 118 healthy PBSC donors performing PBSC collection between January 2000 and December 2007 in our hospital were divided into four groups according to the differ-ent venous accesses. The PBSC collection yield of four groups,including mononuclear cells (MNC) count and CD34+ cells count were observed. Results In the ulnar V-ulnar V group,MNC (5.31±2.29)×108/kg,CD34+ cells (4.78±2.06)×106/kg;ulnar V- antecubital V group,MNC(5.11±2.34)×108/kg,CD34+cells(4.34±1.99)×106/kg;antecubital V- antecubital V group,MNC (5.61±1.73)±×108/kg,CD34+cells (4.60±1.42)×106/kg;ulnar V- radial V group,MNC(4.60±×1.70)×108/kg,CD34+cells (4.05±1.50)×106/kg.There was no statistical differ-ence of the PBSC collection yield between four groups (P>0.05). Conclusions Different venous accesses don't affect the PBSC collection yield in the PBSC healthy donors.
