Objective To investigate the effect of different methods of intestinal preparation on intestinal cleaning for elderly gynecological patients undergoing surgery. Methods Sixty-four elderly patients undergoing gynecological surgery were divided into two groups according to admission seguence. The control group was treated with enema using 800~1000 mL 0.2%soapy water, while the experiment group was treated with enema using sodium phosphate salt oral solution mixed with 800 ~ 1000 mL 0.9% sodium chloride solution. The intestinal cleanness and enema times of the two groups were observed. Results The effect of intestinal cleanliness in the experiment group was better than that in the control group. There was significant differences between the two groups. (P<0.01). Conclusions For the elderly patients undergoing gynecological surgery, sodium phosphate salt oral solution can not only reduce the frequency of enema but also achieve the purpose of cleaning intestinal tract, to ensure the operation effect. It is the ideal method for cleaning bowels of the elderly patients in preoperative prepartion of the surgery.

Objective To survey and control an extensively drug-resistant Acinetobacter baumannii (A.bauman-nii)(XDRAB)lower respiratory tract infection (LRTI)outbreak in intensive care unit (ICU)of a hospital. Methods From October 27,2013 to December 27,2013,5 cases of XDRAB LRTI occurred in ICU,epidemiological investigation was conducted,sources and transmission routes of infection were searched,intervention measures were performed.Results XDRAB were isolated from patients’sputum and environmental object surface,drug-resistant spectrums of isolated XDRAB were almost the same,suggesting the outbreak was due to the contamination of envi-ronment by the same pathogen.54 specimens were taken before disinfection,26 were positive,XDRAB were isola-ted from door handles,sheets and telephones.Investigation concluded that the outbreak of XDRAB infection was due to contamination of indoor environment and equipment,incomplete disinfection,and inadequate hand hygiene compliance of health care workers.After the implementation of a series of control measures,XDRAB was not found,and there was no new XDRAB infection cases.Conclusion Environment contamination is the main cause of this XDRAB healthcare-associated infection(HAI)outbreak,strict implementation of isolation,prevention and con-trol measures of MDROs can effectively control HAI outbreak caused by A.baumannii.

OBJECTIVE:To compare the total flavonoids content and antioxidant activity in the barks,leaves,male flowers and seeds of Eucommiae ulmoides. METHODS:UV spectrophotometry was used to determine the total flavonoids content in differ-ent parts;tests was conducted to clear 2,2′-nitrilobis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS+),1,1-diphenyl-2-trinitro-phenylhydrazine(DPPH)radicals and the reducing ability of Cu2+,using half clear/reduction concentration value(IC50)as evalua-tion indexes,and vitamin C was regarded as positive control. RESULTS:The total flavonoids content of the E. ulmoides from hight to low was as follows as leaves>male flowers>barks>seeds,except there was no significant difference in barks and seeds (P>0.05),the other parts had significant differences (P<0.05);the ability of different parts eliminating DPPH and ABTS+ free radical was as follows as leaves>male flowers>seeds>barks,except there was no significant difference in the indicators of leaves and male flowers(P>0.05),the other parts had significant differences(P<0.05);the ability of reducing Cu2+ free radical was as follows as leaves>male flowers>barks>seeds,there was significant difference in leaves and males flowers with barks and seeds (P<0.05). CONCLUSIONS:The content of total flavonoids in leaves and male flowers is high,and the antioxidant activity is strong,which has a great prospect of exploitation and utilization to make up for deficiencies in barks of E. ulmoides.

Shanyao (Dioscorea opposita Thunb.) is the one of the conventional herbs in the clinical practice, which is good at nourishing yin, and entering the lung, spleen and kidney meridian. Through analysis on all formulae contain-ing Shanyao in past dynasties, we found out the top 30 kinds of traditional Chinese medicine (TCM) herbs for the highest frequency in combination with Shanyao, among which there were 28 herbs recorded in the Shen Nong Ben Cao Jing (Shen Nong's Classic of the Materia Medica) and 23 herbs were considered as the top grade medicinals. This article was focused on the analysis of the compatibility meaning and rules of Shanyao and supplementing medic-inals in order to provide scientific basis for clinical formulae and daily health cultivation so as to make good use of Shanyao.

ObjectiveTo summarize the experience of nursing patients with heat illness combined with respiratory failure. Method The nursing records of 13 patients with heat illness combined with respiratory failure were reviewed for summarizing the nursing measures.Result After treatment and nursing care,12 of them were discharged and 1 died from multiple organ dysfunction. Conclusions Rapid cooling is key to the success of rescue.The nursing measures include keeping respiratory tracts unobstructed and preventing complications from artificial airway and mild hypothermia therapy.

This study aimed to characterize and magnetic resonance imaging (MRI) track the mesenchymal stem cells labeled with polylysine-coated superparamagnetic iron oxide (PLL-SPIO). Rat bone marrow derived mesenchymal stem cells (rMSCs) were labeled with 25, 50 and 100 microg/mL PLL-SPIO for 24 hours. The labeling efficiency was assessed by iron content, Prussian blue staining, electron microscopy and in vitro MR imaging. The labeled cells were also analyzed for cytotoxicity and differentiation potential. Electron microscopic observations and Prussian blue staining revealed that 75% -100% of cells were labeled with iron particles. PLL-SPIO did not show any cytotoxicity up to 100 microg/mL concentration. Both 25 microg/mL and 50 microg/mL PLL-SPIO labeled stem cells did not exhibit any significant alterations in the adipo/osteo/chondrogenic differentiation potential compared to unlabeled control cells. The lower concentration of 25 microg/mL iron labeled cells emitted an obvious dark signal in T1W, T2WI and T2 * WI MR image. The novel PLL-SPIO enables to label and track rMSCs for in vitro MRI without cellular alteration. Therefore PLL-SPIO may potentially become a better MR contrast agent especially in tracking the transplanted stem cells and other cells without compromising cell functional quality.

Objective To investigate low density lipoprotein receptor (LDLR)gene mutation in familial hypercholesterolemia (FH) patients. Methods The proband was given clinical diagnosis of homozygous FH based on marked features and blood lipid tests results. After apoB100R3500Q mutation was excluded, the promoter region and all of the 18 exons of LDLR gene were amplified by touch-downpolymerase chain reaction (PCR). The PCR products were analyzed by single-strand conformationalpolymorphism (SSCP). The PCR products with abnormal single strands were sequenced directly. Thesecondary structures of the mutational and wild type proteins were analyzed and compared byANTHEPROT5.0, and then the tertiary structures of the mutant and wild type LDLR were predicted atSWISS MODEL homepage online. Results A homozygous mutation A606T at exon 13 of the patients wasfound by SSCP and confirmed by DNA sequencing. GOR Ⅰ method in ANTHEPROT5.0 indicates that therandom coils and turns would replace some helixes at the mutation site. The online prediction from theSWISS MODEL homepage indicates the backbone structure of the mutant LDLR has no difference from thewild type one. Conclusion The results suggest the A606T mutation of LDLR gene is the cause of the FH inthis pedigree.

Objective To explore the profile of cognitive response to five facial expressions in 6-to 12-month-old infants. Method One hundred and fifty-five 6-to 12-month-old healthy infants were recruited to view five kinds of normative facial emotional expression pictures which presented on computer screen. The visual attention, self emotional and behavioral responses of each infant toward the facial expressions were recorded by a web camera and then were coded and analyzed from the videotaped observations. Results The visual preference to expressions was different in different groups. 6-to 8-month-old infants looked back ( such as 1.50 ± 0.73,1.39 ±0.81,1.67 ±0.87 ) more to all expressions than 9-to 12-month-old infants( 1.10 ± 0.53,1.04 ± 0.51,1.12 ±0. 61 ). 6-to 8-month-old infants exhibited no obvious difference(P＞ 0.05 ) while 9-to 12-month-old infants exhibited significant difference in self emotional responses (include positive and negative) to different expressions (P ＜0. 05 ). Infants appeared some positive behaviors including looking back at mother,finger-pointing and phonating to expressions during the observation. Conclusions Infants over 6-month-age could discriminate different facial expressions,recognize and comprehend happy expression earlier. 9-to 12-month-old infants began to understand the negative emotional significance of negative facial expressions gradually, but their comprehension to negative emotional expressions was rudimentary.

OBJECTIVE: To analyze the relationship between hemoglobin(Hb) level on admission and survival prognosis of patients with hip fracture. METHODS: From February 2016 to October 2018, 249 elderly patients with hip fracture were surgically treated including 62 males and 187 females;the age ranged from 60 to 91(73.67±10.52) years;the time from injury to operation was (6.79±2.27) d. The clinical and laboratory examination results were collected. The Hb level at admission and the mortality at 30, 90, 180 and 360 days after operation were observed. According to the Hb level at admission, the patients were divided into Hb<120 g/L and Hb≥120 g/L groups. The survival conditions of the two groups at 30, 90, 180 and 360 days after operation were compared and analyzed. Logistic regression was used to analyze the effect of Hb level on death 30, 90, 180 and 360 days after operation. RESULTS: The mortality rates at 30, 90, 180 and 360 days after operation were 5.22%, 9.24%, 16.87% and 20.48% respectively. The level of Hb at admission was a risk factor for prognosis and death 30, 90, 180 and 360 days after operation(P<0.05). The OR(95% CI) were 2.431(1.475-4.006), 2.625(1.468-4.695), 2.276(1.320-3.925) and 2.082(1.221-3.551) respectively. CONCLUSION The level of Hb at admission can affect the survival and prognosis of elderly patients with hip fracture. We should further study how to manage the level of Hb before operation.
