Objective To investigate the effect of continuing nursing on elderly patients with high risk of pressure sores. Methods High-risk elderly patients with pressure sores healed in our hospital in January 2014 to December 2014 were divided into control group and observation group with 130 cases in each group by random number table. The control group received routine follow-up service, while the observation group were intervened by continuing nursing care. To observe the differences before and after the interventions in both groups on the patient's quality of life and the incidence of pressure sores. Results There was statistically significance on mental function scores (t=12.393, P=0.000), social function score (t=8.459, P=0.000) and overall quality of life score (t=12.750, P=0.000) between the two groups after the interventions. Meanwhile, there was no statistically significance on material life score (t =-1.913, P=0.057) and physical function score (t=-0.328, P=0.744). The difference of the re-occurrence of pressure sores in the two groups was statistically significant (χ2=35.96, P=0.000), either. Conclusions Continuing nursing intervention can obviously reduce the risk the re-occurrence of pressure sores on high-risk elderly patients, in particular to improve the quality of life aspects of mental function and social function in patients, meanwhile with no obvious improvement in that of material life and body functions.

Objective To explore the changes of Clara cell secretory protein(CCSP) in asthmatic children and the effects of inhaling glucocorticoid (ICS) on CCSP.Methods Sixty children with asthma were selected as asthma group(in which 39 cases were male and 21 cases were female,aged 3-12 years old) and 30 healthy children were selected as healthy control group(in which 20 cases were male and 10 cases were female,aged 3-12 years old).Venous blood samples were collected in asthma group and healthy control group in morning before breakfast,and then sera were obtained by centrifuge in speed of 1 500 r?min-1 in 10 min.The dynamic levels of CCSP were measured in sera by enzyme-linked immunosorbent assay.Results 1.In asthmatic children,the CCSP levels in acute episode,3 months after ICS,6 months after ICS, and 12 months after ICS[(5.140?2.331)?g?L-1,(8.730?3.392)?g?L-1,(10.510?2.813)?g?L-1]were all lower than that in healthy control group[(13.230?4.010)?g?L-1](Pa0.05).2.Compared with acute episode,the patients who ICS for 3 months,6 months and 12 months had significantly higher levels of CCSP (Pa0.05).Conclusions CCSP may play a protective role in the airway inflammation of asthma.Glucocorticoid may increase CCSP level in asthmatic children.Glucocorticoid and CCSP may cooperate in anti-inflammation in airway of asthmatic children.

Objective:To observe the clinical efficacy of Ba-pulling and Qian-traction manipulation with neck suspension and movement for acute cervical radiculopathy. Methods: A total of 85 patients who met the inclusion criteria were randomized into an observation group and a control group by random numbers, with 43 cases in the observation group and 42 cases in the control group. The observation group was treated with Ba-pulling and Qian-traction manipulation with neck suspension and movement;while the control group was treated with Bashen-pulling and stretching manipulation in a supine position. The treatment was performed once a day, 10 times as a treatment course. The therapeutic efficacy was evaluated after 1 treatment course, and the changes in the scores of visual analog scale (VAS) and neck disability index (NDI) were observed. Results: The total effective rate was 97.7% in the observation group, and 83.3% in the control group, and the difference between the two groups was statistically significant (P＜0.05). After treatment, the VAS and NDI scores of both groups were significantly decreased (both P＜0.01), and the differences in the VAS and NDI scores between the two groups were statistically significant (both P＜0.01). Conclusion: Both Ba-pulling and Qian-traction manipulation with neck suspension and movement and Bashen-pulling and stretching manipulation in a supine position can relieve pain and improve cervical function in patients with acute cervical radiculopathy, and Ba-pulling and Qian-traction manipulation with neck suspension and movement can produce more significant efficacy than Bashen-pulling and stretching manipulation in a supine position.

Objective To investigate the proliferation and identification of dendritic cells(DC)de- rived from peripheral blood of patients with bladder cancer in vitro.Methods The mononuclear cells were prepared from peripheral blood of patients with bladder cancer by Ficoll-Hypaque centrifugation method,and were induced by the recombinant cytokines hGM-CSF(50 ng/ml),hlL-4(10 ng/ml)and hTNF-?(50 ng/ ml)for 2 weeks.The growth and morphology of DC were observed through the phase contrast or electron mi- croscope,and their pheuotypes were determined by flow cytometry.The capacity of DC to activate T cell-de- pendent anti-tumor immune responses was tested by MTT method.Results The DC cultured in vitro turned into suspensive growth from adhesive situation on the 6th day,then the number of DC increased con- tinuously and the cells showed the irregular morphologic appearance of DC with veiled edges on the 8th day. Flow cytometry showed that the mature DC expressed high levels of specific markers such as CD_(1a),CD_(83), CD_(86)and HLA-DR.T cells activated by DC showed strong cytotoxicity to bladder cancer cell line BIU87 with a killing rate of(48.8?3.7)%,while the killing rate of T cells which were not activated by DC was(25.7?1.5)%;the difference of the rate between them was significant(P＜0.01). Conclusions The DC can be cultured from peripheral blood of patients with bladder cancer by induction of rhGM-CSF,rhIL-4 and hT- NF-?in vitro.This may lay an experimental foundation for further research on DC vaccine.

Objective To evaluate the effects of capsule endoscopy in the diagnosis and prognosis of small bowel tumors.Methods Three hundred and fifty-eight consecutive patients who underwent capsule endoscopy for suspected small bowel disease during May 2002 to Feb.2007 were examined.The final diagnosis was confirmed pathologically.Results Thirty-three(9.22%) out of 358 patients were identified as small bowel tumors[male 14/female 19,mean age(51?17)years].Of them,23(69.70%) patients had malignant tumors and ten(30.30%) had benign tumors.Obscure gastrointestinal bleeding were found in 26 cases,bleeding with abdominal pain in 2 cases,bleeding with diarrhea in 1 case,abdominal pain in 2 cases,abdominal pain with diarrhea in 1 case and vomiting in 1 case.All patients with benign tumors underwent surgery for their tumor.No further bleeding or abdominal pain after resection was found in all but one patient.Of the patients with malignant tumors,all expect two underwent surgery.Three patients accepted palliative surgery while eighteen patients received a curative resection.The locations of the tumor detected by capsule endoscopy were correlated well with the results of surgery.Conclusions Capsule endoscopy promises a higher diagnostic yield in small bowel tumors. h may improve the diagnosis of small bowel tumors and alter management thoroughly.

To explore a new method to identify Moutan Cortex to guarantee its safe use, internal transcribed spacer 2 (ITS2) sequence was used to identify Moutan Cortex and its adulterants. DNA was extracted and target fragments were amplified. Sequences were analyzed and assembled by CodonCode Aligner V3.7.1. Genetic distances were computed and phylogenetic tree was constructed based on kimura 2-parameter (K2P) model by MEGA 5.0. The length of the 20 ITS2 sequences of Moutan Cortex from nine different places is 227 bp, and no variation site was detected. The maximum inter-specificK2P distance of Moutan Cortex is 0, the minimum intra-specific K2P distance is 0.041, the average intra-specific K2P distance is 0.222. According to NJ analysis, Moutan Cortex from different places can get together as one branch with bootstrap support values 99%, which indicates Moutan Cortex can be easily distinguished from its adulterants. Using ITS2 sequence can accurately identify Moutan Cortex and its adulterants, it is an effective supplementary to traditional identification methods.

OBJECTIVETo explore the relationship between angiotensin converting enzyme (ACE) gene single nucleotide polymorphisms (SNP) and premature coronary heart disease (PCHD) patients with blood stasis syndrome (BSS).

METHODSrs4343, rs4293, and rs4267385 were selected at SNP from ACE gene. Allele and genotype were detected. Frequencies of allele and genotype were compared by using time-of-flight mass spectrometry technique (TOF-MS).

RESULTSCompared with the healthy control group, genotype of rs4293 and rs4267385 in ACE gene were similar, but there was statistical difference in polymorphisms and allele frequencies of rs4343 in the I and II group (P < 0.05, P < 0.01). The frequency of G allele was higher in the 3 groups than in the healthy control group (P < 0.05, P < 0.01). The relative risk analysis showed that the risk for PCHD occurrence in G allele carriers at rs4343 (GG +AG) was 3. 6 times the risk in non-G allele carriers (95% CI: 1.224-10.585, P = 0.02). There was also statistical difference in sex, age, TC, and TG after adjusted Logistic regression analysis (OR = 3.994, 95% CI: 1.230-12.974, P = 0.021).

CONCLUSIONThe polymorphism at rs4343 (G2350A) might be one of risk factors for PCHD occurrence, but not a predisposing factor for PCHD patients of BSS.

Objective To evaluate the performance of nested PCR in the detection of different fungi in paraffin wax embedded tissues. Methods Forty-four tissue samples were resected from rats infected with Fonsecaea monophora, patients with chromoblastomycosis, sporotrichosis or penicilliposis marneffei followed by preparation of paraffin wax embedded tissue sections for pathological examination and DNA extraction. Nested PCR was performed by using specific primers targeting the ribosomal DNA of Fonsecaea, Sporothrix and Penicillium marneffei, respectively. The sensitivity and specificity of nested PCR were analyzed and compared with those of pathological examination. Results The nested PCR showed positive results in 8 of 20 samples from rats with chromoblastomycosis, 7 of 10 samples from patients with sporotrichosis and all of the 10 samples from patients with penicilliposis marneffei, but not in the control samples. In the detection of Fonsecaea,Sporothrix schenki and Penicillium marneffei, the sensitivity was 40% ,70% and 100%, respectively, and the specificity was consistently 100%, for the nested PCR. Pathological examination revealed fungal elements in 95%, 70% and 80% of the corresponding samples, respectively. Conclusion Detection of fungal DNA in paraffin wax embedded tissue by nested PCR can be applied to the diagnosis of deep mycosis, especially to the diagnosis of penicilliposis marneffei.
