Objective:To investigate the curative effect and safety of slow continuous ultrafiltration(SCUF) treatment on congestive refractory heart failure with renal failure, and to investigate the correlation between fluid balance and the postoperative complications.Methods:Thirty patients with congestive refractory heart failure with renal failure were chosen to receive slow continuous ultrafiltration treatment after deep vein catheterization, blood flow volume being 100-150 ml/min and therapy time being 24h. PiCCO was used to monitor the hemodynamic parameters, along with the change of blood pressure, blood oxygen saturation, heart beat and electrolyte.Results: After the slow continuous ultrafiltration treatment, the hemodynamic parameters of all patients showed obvious improvements, with better results on cardiac function and electrolyte balance. All the patients patients developed cardiopulmonary complications postoperatively have a larger total fluid balance of the first two days postoperatively than those without complications.Conclusion:SCUF have therapeutic effect and safety for treating congestive refractory heart failure with renal failure, and the status of the fluid balance can be a predictor of the postoperative morbidity and mortality.

Objective To establish criteria for determination of sputum retention in elderly patients with non-ar-tificial airway. Methods Interview and Delphi methods were used to preliminarily determine clinical indication of sputum retentionand its classification through two-round expert consultation among 25 experts. Final criteria for de-termination of sputum retention were determined through experts group discussion. Results During the two rounds of consultation,all the questionnaires were collected,the experts' authority coefficients were 0.936 and 0.926 respec-tively,and the coordination coefficient of expert opinion was statistically significant.Criteria for determination of spu-tum retention included ineffective cough plus auscultation phlegm sound,with or without complaining of sputum,de-creased blood oxygen saturation,difficulty breathing and cyanosis. Conclusion Based on expert consultation and ar-gument,the criteria for determination of sputum retention can facilitate clinical nurses to detect sputum retention.

OBJECTIVE:To investigate the expression difference and its mechanism of miR-27a-3p and HOXB8 protein in cer-vical cancer tissues of HPV16-positive and HPV16-negative patients. METHODS:A total of 120 patients with cervical cancer in our hospital during Jan. 2012-Jan. 2016 were divided into HPV16-positive group(60 cases)and HPV16-negative group(60 cases) according to HPV16 infection situation. The expression of miR-27a-3p mRNA and HOXB8 mRNA in cervical cancer tissue were de-tected by RT-qPCR. The expression of HOXB8 protein was detected by Western blotting assay. DNA methylation level of miR-27a-3p promoter region was detected by nested-down methylation specific PCR (nMS-PCR). Histone methylation level of miR-27a-3p promoter region was detected by chromatin immunoprecipitation PCR (CHIP-PCR). The expression of miR-27a-3p mRNA and HOXB8 mRNA were detected after transfecting miR-27a-3p mimic and inhibitor into Human cervical cancer cell line SiHa,respectively. RESULTS:The expression of miR-27a-3p in HPV16-positive group was significantly lower than HPV16-nega-tive group,while HOXB8 mRNA and protein expression,DNA and histone methylation levels of miR-27a-3p promoter region were significantly higher than HPV16-negative group,with statistical significance (P<0.05 or P<0.01). After transfecting miR-27a-3p mimic into SiHa cells,the expression of miR-27a-3p was increased significantly,while that of HOXB8 mRNA was de-creased significantly;after miR-27a-3p inhibitor transfection,the expression of miR-27a-3p was decreased significantly,while that of HOXB8 mRNA was increased significantly,with statistical significance(P<0.01). CONCLUSIONS:HPV16 may down-regu-late the expression of miR-27a-3p through DNA methylation and histone methylation of promoter region,so as to influence the gen-eration and development of cervical cancer. HOXB8 may be the target protein of miR-27a-3p.

Ventilator related events is a new concept proposed by the America Center for Disease Control and Prevention of the United States. Compared with ventilator-associated pneumonia, ventilator related events has objectivity in diagnosis. In 2013, the National Health Safety Network replaced ventilator-associated pneumonia monitoring in adult inpatients with ventilator-associated event monitoring. This review mainly introduces the concept of ventilator-related events, the evaluation of the relationship between ventilator-related events and respiratory pneumonia, the monitoring situation at home and abroad, and the related factors of ventilator-related events, so as to lay a foundation for the further study in the future.

OBJECTIVE:To provide reference for suitable selection of antibacterial ophthalmic preparation in the clinic. METHODS:The application of antibacterial ophthalmic preparation in a hospital during Jan. 2013-Dec. 2016 were summarized and analyzed to calculate DDDs. The results of bacterial culture and identification,drug sensitivity test were collected. The correlation of DDDs of antibacterial ophthalmic preparation with resistance rates of bacteria was analyzed by using Pearson test. RESULTS:During 2013-2016,there were 7 categories of antibacterial ophthalmic preparations used in this hospital,involving 10 types. To-tal DDDs showed an upward trend with average annual growth rate of 26.16％. DDDs of Tobramycin (dexamethasone) eye drops were the highest for consecutive 3 years (2013-2015). Gatifloxacin eye drops/eye gel and Ofloxacin eye drops/eye oint-ment ranged 2nd-4th place in the list of DDDs. A total of 26143 ocular specimens were examined,and 21 kinds of bacteria were detected,involving 6221 strains with detection rate of 23.80％. Top 3 bacteria in the list of detection rate were Staphylo-coccus epidermidis (3067 strains),Streptococcus pneumoniae (470 strains) and Staphylococcus aureus (321 strains). Resistance rates of above 3 kinds of bacteria to erythromycin were all higher than 70％,while they were sensitive to rifampicin,chlorampheni-col,gentamicin and levofloxacin,etc. Compared to previous year,the average resistance rates of rifampicin(in 2015),gentamicin (in 2015,2016),tetracycline(in 2015),ofloxacin(in 2014,2015),levofloxacin(in 2016)and gatifloxacin(in 2016)had statisti-cally significant differences(P<0.05). DDDs of tetracycline was positively associated with its average resistance rate(r=1.000,P<0.05),and DDDs of other antibacterials had nothing to do with resistance rate(P>0.05). CONCLUSIONS:The main ocular infec-tions were S. epidermidis,S. pneumoniae and S. aureus. DDDs of tetracycline is certainly associated with resistant rates. Regulating clinical use of antibacterial ophthalmic preparation is important for delaying the development of bacterial resistance.

A novel fluorescent switch was constructed based on poly 3-{[ 1-( 2-hydrazino-2-oxoethyl ) piperidin-4-ylidene] methyl}thiophene ( PMTH ) in the presence of Pb2﹢ or S-adenosylmethionine ( SAM ) . The switch turned off in the presence of Pb2﹢owing to complex effect, and the fluorescence intensity of PMTH solution was efficiently quenched by Pb2﹢ ions. Upon adding SAM to the Pb2﹢-PMTH solution, which was stronger Pb2﹢ chelators, it could form more stable SAM-Pb2﹢, the Pb2﹢ ion was displaced from PMTH and the fluorescence of PMTH was recovered. By triggering the turn-on signal of PMTH, a new discrimination ability toward SAM method for the determination of SAM was established. The effects of the interaction on the fluorescence spectral characteristics of these Pb2﹢-PMTH and Pb2﹢-SAM complexes in H2 O-CH3 CH2 OH(4:1, V/V) solution, suitable reaction conditions and influencing factors were investigated. This method offered good sensitivity and selectivity for detecting SAM in the presence of amino acids and metal ions. Under optimum conditions, the concentration of SAM in the range from 1. 0 × 10-8-2. 0 × 10-6 mol/L exhibited a linear relationship with the relative fluorescence intensity. The regression equation was △I = 68. 51﹢72. 32c (μmol/L), the correlation coefficient r=0. 9982. The limit of detection was 8. 72×10-9 mol/L. The system was successfully applied for detecting SAM in human serum, urine and injection samples.

BACKGROUND:Cleft palate repair with levator veli palatini retropositioning can achieve good effects on pharyngeal function and voice quality by dissecting the muscle and rebuilding the muscle function only at the incision, without opening the mucoperiosteal flap, OBJECTIVE: To investigate the clinical effects of cleft palate repair with levator veli palatini retropositioning versus traditional surgery treatment on speech disorder correction. METHODS:Totaly 176 children with cleft palate were randomly assigned into treatment group and control group, 88 cases in each group. Patients were subjected to traditional surgery treatment in the control group and levator veli palatini retropositioning in the treatment group. RESULTS AND CONCLUSION:The postoperative speech inteligibility in the treatment group and the control group were 81.8% and 54.5%, respectively, and there was a significant difference between the two groups (P < 0.05). After cleft palate repair, the folowing indicators were al improved in the two groups, including soft palate functional length at static state and when pronouncing, and soft palate elevation angle (P < 0.05), and moreover, these indicators were better in the treatment group than the control group (P < 0.05). Scores on high nasal tone and rhinorrhea tone were decreased significantly in the two groups after repair, and the scores were significantly lower in the treatment group than the control group (P < 0.05). These findings indicate that cleft palate repair with levator veli palatini retropositioning can effectively rebuild soft palate function and perfect velopharyngeal competence in patients, which is of great significance for speech disorder correction and voice quality recovery.

Objective To explore the condition of MYC/BCL2 protein coexpression in 245 patients with diffuse large B-cell lymphoma (DLBCL)and to find the correlations among MYC/BCL2 protein coexpres-sion,the germinal center B-cell-like (GCB)subtype and non-GCB subtype.Methods Paraffin-embedded lymphoma samples from 245 patients with DLBCL were studied using immunohistochemistry for MYC,BCL2, CD10,BCL6,MUM1 and KI67.And the protein expressions of them were analyzed.Results In the speci-mens of 245 patients with DLBCL,the patients with non-GCB were 163 (66.5%),and the patients with GCB were 82 (33.5%).The group of MYC/BCL2 protein coexpression comprised 35.9% (88/246)of the all patients.Non-GCB subtype group had a significantly higher frequency of MYC/BCL2 protein coexpression than the GCB subtype group (41.7%∶24.4%;χ2 =7.116,P=0.008).Conclusion The data shows that MYC/BCL2 protein coexpression occurs significantly more commonly in the non-GCB subtype.We can predict prog-nosis and choose therapeutic regimen base on the assessment for MYC and BCL2 protein expression.
