In the early 20th century,the term Nursing was introduced into China.In 1884,with the arrival of the first batch of missionary nurse,modern nursing initiated by Nightingale was introduced into China and greatly changed the way of care.The missionary nurses were full of enthusiasm for the spreading Gospel of Christ,the love for nursing care and the empathy for Chinese people;and encountered the lack of staff and material,the mis-understanding and resistance from the local people and other multiple tests.With the untiring effort of them and the trained local nurses,China had led the international care in nursing education and practice standard.Based on this,nursing in Shandong gradually rose and had an unprecedented development as a new medical subject.By clearing up and consulting Chinese and English historical materials,this paper reviewed the 60 years of the mission-ary nurses in China,saw the early development of nursing in our country from the budding and development of Shandong nursing and provided more insights for understanding and solving the complex problems contemporary Chinese nursing faces.

OBJECTIVE:To establish the purity determination of bisacodyl by differential scanning calorimetry(DSC)and the valuation of uncertainty. METHODS:DSC was conducted to detect the purity of bisacodyl and determine the optimal testing condi-tions. According to related standards,indium enthalpy change values,measurement repeatability,weighing process,instrument tem-perature deviation and system software deviation were systematically analyzed. The results were verified by HPLC. RESULTS:When the fiducial probability P was 0.95,the standard value and uncertainty of content of bisacodyl was (99.88 ± 0.06)% mea-sured by DSC. Weighing process,instrument temperature deviation and system software deviation had great effects on the total un-certainty. The result of HPLC and DSC were the same. CONCLUSIONS:The established DSC can quickly and accurately determine the chemical purity of bisacodyl. The uncertainty evaluation is reliable. Regularly calibrated and verificated equipment and strict con-trol of the weighing process will help to improve the accuracy measured by DSC;and it provides a new analysis method for the de-termination of purity of bisacodyl.

Objective To investigate the influence of FOXP 3 expression in pancreatic carcinoma cells (PCCs) on the maturation and immunologic function of dendritic cells (DCs).Methods The siRNA sequences targeting FOXP3 gene (siRNA-FOXP3) and negative control siRNA (siRNA-NC) were specifically designed and transfected into PCCs , then the level of IL-10 and TGF-β1 of culture supernatant were detected by ELISA.The supernatants of pancreatic carcinoma cell transfected by FOXP 3-siRNA were collected , then it was mixed with GM-CSF and IL-4 to induce the differentiation of DCs .Flow cytometric analysis were used to measure the expression of surface markers CD 86 , CD80 , HLA DR on DCs which were treated with supernatants .

Objective To investigate the role of AcrAB-TolC efflux pump in fluoroquinolones resistance by Shigella. spp and to explore the significance of AcrAB-TolC efflux pump on mutation of acrR, soxS and marOR as well as on drug re?sistence. Methods Drug resistant bacteria were selected by Kirby-Bauer disk diffusion test. After addition of efflux pump inhibitor carbonylcyanide-m-chlorophenylhydrazone (CCCP), change of minimal inhibitory concentration (MIC)s of nilidixic acid, Levofloxacin, ofloxacin, ciprofloxacin and Norfloxacin were examined. The DNA binding region of acrA, acrB, soxS, acrR and marOR gene in these mutants were amplified by PCR and sequenced. Results Among the 159 clinical isolates of Shigella,11 strains are resistant to fluoroquinolone. After the addition of CCCP, MICs of 2 fluoroquinolone resistant strains decreased; the MICs of 7 fluoroquinolone resistant strains did not change; MICs of 2 fluoroquinolone resistant strains in?creased. The corresponding nucleotides C, A, T, T on the 36th to 39th of marOR gene were missing, showing by sequencing, in fluoroquinolone resistent strains which might be regulated by the efflux pump gene AcrAB-TolC. Conclusion Efflux pump inhibitor could restrain the activity of efflux partially. The mutations of marOR might play an important role in fluoroquino?lone resistent by shigella.

Objective To explore carrying rates of class 1, class 2 integrons as well as ISCR1 in Shigella isolates and their connection with drug resistance. Methods Antibiotic sensitivities were detected by K-B disk diffusion in 159 clinical isolates. Total bacteria DNA was prepared through boiling the isolates and the DNA was then used as template for PCR am?plification. PCR, ZSCR1 and sequencing analyse of integrons were applied to all of them. Results were compared by Blast and GenBank. Results Antibiotic sensitivity results showed that in the S. flexneri strains the incidence of resistance to tet?racycline and streptomycin were 88.68%and 81.13%in the S. flexneri strains while the incidence of resistant to chloram?phenicol and trimethoprim-sulfamethoxazol were both 56.60%, and the incidence of multidrug drug resistance was 77.36%. In the sonnei strains, the incidence of resistance to ampicillin, trimethoprim-sulfamethoxazo were 97.17% and 95.28%, 83.96%and 76.42%respectively, and the incidence of multidrug resistance was 98.11%. Among all isolates, 118 were class 1 integron positive , 70 were class 2 integron positive and 89 were double positives. For those 118 isolates that are positive of class 1 integron, 23 were typical while 95 weres atypical. The gene cassettes of typical class 1 integrons contains aadA2, aa?dA1, dfrⅠ, blaoxa-10 and blaoxa-1. IntI1, aadA, blaoxa-1 and IS1 were included in the gene cassetes of the atypical class 1 integrons. Class 2 integrons positive isolates carried gene cassttes which include dfrA1, satl and aadA1. No ISCR1 was found in any isolate. Integron carriage strains were closely associated with higher rate of multiple antibiobic resistance com?pared with the organisms without integrons (90.65%,50%, P<0.05). Conlusion Class 1 and class 2 integrons were widely existence in Shigella isolates and were related to the multidrug resistance.

Ovotestis is a rare disorder of sexual differentiation in which the gonads have both ovarian and testicular elements. The patients always present with ambiguous external genitalia, and there are usually with serious disorder between chromosomal sex, gonadal sex, social sex, and psychological sex. The definite diagnosis and gender confirmation, appropriate surgery in internal genitalia and orthomorphia in external genitalia, as well as psychological support are essential for a multidisciplinary medical group in managing this disease. The medical data of two children with ovotestis who were reared as boy or girl respectively were analyzed.

Objective To evaluate the effect of isoflurane preconditioning on inflammatory responses during spinal cord injury (SCI ) in rats .Methods Sixty adult male Sprague-Dawley rats ,weighing 250-300 g , were randomly divided into 3 groups ( n= 20 each ) using a random number table :sham operation group (S group) , SCI group , and isoflurane preconditioning group (I group ) . The animals were anesthetized with intraperitoneal pentobarbital sodium 40 mg/kg .SCI was produced by a weight-drop contusion at the T10 level .The rats inhaled 2% isoflurane for 2 h ,and the model was established at 24 h after the end of isoflurane inhalation in I group . Neurological function was assessed and scored by using the the Basso , Beattie , Bresnahan (BBB ) Locomotor Rating Scale on 7 days after SCI .Five rats in each group were then chosen and spinal cord specimens were obtained and cut into sections which were stained with haematoxylin and eosin for determination of the viable neuron count .Fifteen rats in each group were sacrificed and the spinal cord was removed for detection of nuclear factor kappaB (NF-κB ) and interleukin-1β (IL-1β) expression (by Western blot ) .Results Compared with S group ,BBB score and the number of viable neurons were significantly decreased ,and the expression of NF-κB and IL-1βprotein was up-regulated in SCI group ( P<0.05) .Compared with SCI group ,BBB score and the number of viable neurons were significantly increased ,and the expression of NF-κB and IL-1βprotein was down-regulated in group I ( P<0.05 ) .Conclusion The mechanism by which isoflurane preconditioning protects the spinal cord is related to inhibition of inflammatory responses in rats .

Objective:To explore the influence of rosuvastatin in the lipid levels, atherosclerosis plaque and apoptosis in the plaque of atherosclerotic apolipoprotein E (ApoE)-knockout mouse models, and to clarify the mechanism of rosuvastatin in inhibiting atheromatous plaque and apoptosis in the plaque.Methods:Thirty healthy six-week old male mice were randomly divided into high fat diet group (n=10),rosuvastatin group (n=10)and general diet control group (n=10).The mice in first two groups were fed with high fat diet,and the mice in general diet control group were fed with general diet;4 weeks later the mice in three groups were respectively given 0.9% NaCl solution,rosuvastatin (10 mg·kg·d-1 )and 0.9% NaCl solution by gavage for 8 weeks.And then ELISA was used to detect the serum lipid levels,the area of atherosclerotic plaque was measured by HE staining, and the apoptosis in plaques was detected by TUNEL method;the expression of apoptosis-assoicated gene Bax protein was measured by immunohistochemical staining.Results:Compared with high fat diet group,the levels of total cholesterol (TC)and low density lipoprotein cholesterol (LDL-C)of the mice in rosuvastatin group were significantly decreased (P<0.05 or P<0.01),and the 1evel of high density lipoprotein cholesterol (HDL-C)was significantly increased (P<0.01).The aortic atherosclerotic plaque of the mice in high fat diet group was massive with a great quantity of foam cells, cholesterol crystal, necrotic cells and inflammatory cells in the plaque;the aortic atherosclerotic plaque of the mice in rosuvastatin group was smaller with less foam cells,necrotic cells and inflammatory cells;the aortic atherosclerotic plaque area of the mice in rosuvastatin group was significantly smaller than that in high fat diet group (P<0.01);the apoptotic index in the aortic atherosclerotic plaque of the mice in rosuvastatin group was significantly lower than that in high fat diet group (P<0.01).Compared with high fat diet group,the expression of Bax protein in rosuvastatin group was significantly decreased.Conclusion:Rosuvastatin may inhibit the progression of atherosclerotic plaque and the apoptosis in plaques through mitochondrial pathway.

Objective To investigate the effects of dexmedetomidine pre-treatment on pneumonocyte apoptosis and CCAAT/enhancer binding protein homologous protein (CHOP) in acute lung injury (ALI) induced by ischemia/reperfusion (I/R) during orthotopic liver transplantation in rats.Methods Forty adult male Sprague-Dawley (SD) rats were randomly divided into four groups by random number table method: sham operation group, I/R model group, dexmedetomidine low dose group and dexmedetomidine high dose group, 10 rats per group. Hepatic artery was ligated and cut off by two cuff method, and the portal vein was completely opened after donor liver transplanted into the recipient, thus, a hepatic I/R model was established. The perihepatic ligaments of rats were just separated after laparotomy in sham operation group and no other special treatment was performed. One hour prior to I/R, dexmedetomidine at a dose of 2.5μg·kg-1·h-1 and 5.0μg·kg-1·h-1, respectively, were pumped intravenously and finished within 1 hour in the rats of low dose group and high dose group. After experiment, the lung tissue was taken, and the lung wet/dry weight (W/D) ratio was determined. Pathological changes of lung tissue were observed and alveolar damage index of quantitative assessment (IQA) was tested by light microscope, and changes of ultrastructure of lung tissue were observed by transmission electron microscope. The mRNA and protein expressions of CHOP were detected respectively by reverse transcription-polymerase chain reaction (RT-PCR) and Western Blot. The apoptosis in lung tissue was determined by terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) method and apoptosis index (AI) was calculated.Results Compared to sham operation group, the lung W/D ratio (4.94±0.84 vs. 2.29±0.54), IQA [(40.52±5.15)% vs. (4.55±1.85)%] and AI [(36.57±5.85)% vs. (2.85±0.95)%] in I/R model group were significantly higher (allP < 0.01); remarkable injury of lung tissue was confirmed by light microscope and transmission electron microscope in the I/R model group. Compared to I/R model group, the W/D ratio (3.29±0.85, 2.68±0.78 vs. 4.94±0.84), IQA [(23.69±2.62)%, (15.86±3.61)% vs. (40.52±5.15)%] and AI [(25.73±3.71)%, (14.66±2.61)% vs. (36.57±5.85)%] in dexmedetomidine low and high dose groups were markedly lower (allP < 0.01); under light and transmission electron microscopes, the injury of lung tissue in these two dose groups was notably alleviated. There was a large amount of apoptotic cells of pulmonary vascular endothelium and alveolar epithelium in I/R model group, while the cell apoptosis was distinctly decreased in dexmedetomidine low and high dose groups compared to that in model group. Compared to sham operation group, the expressions of CHOP mRNA [absorbance (A) value: 0.96±0.18 vs. 0.43±0.08] and protein (gray scale: 2.79±0.74 vs. 1.02±0.27) were significantly higher in I/R model group (bothP < 0.01). Compared to I/R model group, the expressions of CHOP mRNA (A value: 0.69±0.13, 0.56±0.12 vs. 0.96±0.18) and protein (gray scale: 1.96±0.58, 1.34±0.49 vs. 2.79±0.74) were significantly lower in dexmedetomidine low and high dose groups, the decrease in dexmedetomidine high dose group being more marked (allP < 0.01).Conclusion The pretreatment of dexmedetomidine can protect lung tissue against I/R injury during liver transplantation in rats, and the mechanism may be related to the suppression of CHOP activation and alleviation of lung tissue cell apoptosis.
