Objective To study impact of traditional Chinese medicine liquid combined with compression method on wound healing of anal fistula after towing line operation. Methods 120 patients with anal fistula were divided into observation group and control group by random number table including 60 cases respectively. Observation group were given liquid washing fistula combined with sand bags oppression in wound on the basis of conventional nursing; Control group were given the routine nursing care. Curative effect, pain, wound healing time, recurrence rate and degree of satisfaction of two groups were compared. Results Clinical curative rate of observation group was 98.33% (59/60), which was obviously higher than 85.00% (51/60) of control group, and there was statistically significant difference (χ2=6.981 8, P<0.01). Postoperative pain score at the 1st, 2nd, 3rd day of observation group was (2.98± 2.01), (2.97±1.94), (3.06±1.92) points, which was lower than (5.48±1.76), (5.52±1.91), (5.42±2.01) points (t=13.336 9, 13.514 8, 12.261 3, P < 0.01). Wound healing time of patients in observation group was (23.96±3.28) days, which was obviously less than (32.34±4.51) days of control group (t=6.285 1, P<0.01);Recurrence rate in observation group was 1.67%(1/60), which was obviously lower than 11.67%(7/60) of the control group, and the difference was statistically significant (χ2=4.821 4, P < 0.05). Conclusions Applying traditional Chinese medicine liquid combined with compression method in wound healing of anal fistula after towing line operation can promote wound healing, improve curative effect, prevent recurrence, and improve patients′satisfaction.

Objective To discuss the demands of replacement care service for family caregivers of the aged in Zhengzhou City,so as to provide the reference for replacement care service of the aged.Methods A total of 145 family caregivers of the aged were collected in Zhengzhou city and were investigated with a self-designed questionnaire.Results In the 145 questionnaires,106 were valid.81 (76.4％) of them expressed needing to be replaced in the process of care,and 68 (64.1％) were willing to accept replacement care service.Order of demands of replacement service content was daily life nursing (77,72.6％),disease (66,62.3％) and psychological care (60,56.6％),etc.Influencing factors of selecting replacement care service for family caregivers included quality of service (63,59.4％),service price (38,35.8％) and professional skill (37,34.9％).The degree of demand of different ages,different careers,as well as different duration of daily care of family caregivers was statistically significant for replacement care service.Conclusions The degree of demand of family caregivers of the aged for replacement care service was higher.The government needs to establish replacement care service mechanism which is suitable for China's national conditions through policy guidance and support.

Objective To study the time extended for getting emergency intervention in different modes of transportation and factors influencing the modes of transportation of patients with ST elevation myocardial infarction (STEMI).Methods A total of 564 consecutive patients with STEMI admitted from September 2013 to June 2016 were enrolled in the study.The clinical data about time consumed for getting emergency intervention and modes of transportation were collected.Results According to the mode of transportation,patients were divided into three groups:emergency care system (EMS) transportation group (n =96),self-transportation group (n =206) and referral group in which the patients were sent in from other hospitals (n =262).EMS transportation group had significantly shorter total ischemic time before emergency treatment than self-transportation group (229 rin vs.418 min,P ＜ 0.05) and referral group (229 min vs.512 rin,P ＜ 0.05),and significantly shorter length of pre-hospital time than self-arrival group (55 min vs.110 min;P＜0.05) and referral group (55 min vs.372 min;P＜0,05).The referral group had longer pre-hospital time and the self-transportation group had longer door-to-balloon time,but there was no difference in total ischemic time between the self-arrival and referral group (Z =-1.882,P =0.068).Multivariate logistic regression was used to analyze influence factors in mode of transportation:(1) patients characterized with high school or university education,profession of civil service,and their transportation distance more than 30 km were greater in number than referral group (P ＜ 0.05);(2) patients identified with senior middle school education,staff member of public sectors or company,their transportation distance less than 30 km,and with killip grade above Ⅱ were more likely to have EMS transport (P ＜ 0.05);(3) patients defined as businessmen without taking out new rural cooperative medical insurance,taking up transportation distance less than 80 km,and subjecting to killip grade Ⅰ had a higher proportion of individuals of this kind taking self-transportation (P ＜ 0.05).Conclusion Mode of transportation is an important factor that affects the time extended to get emergency intervention.Education level,occupation,medical insurance type,transportation distance,killip grade are associated with modes of transport.

Yeast Elongation protein 3 (yElp3), the catalytic subunit of the multi-subunit histone acetyltransferase elongator complex, is involved in histone acetylation and transcription, exocytosis and tRNA modification. To study the complex function of yElp3 in yeast, we amplified the yElp3 gene fragment encoding 73aa in the N-terminal from plasmid pYES2-yElp3, and then cloned it into pMXB10 to construct the recombinant plasmid pMXB10-yElp3-219. We expressed the fusion protein in E. coli BL21 (DE3), then purified it by chin affinity column, and finally obtained the soluble purified protein (8.0 kD), which was used to immune the rabbits for acquiring antiserum. ELISA and Western blotting indicated that the polyclonal antibody was of high titration and specificity. Chromatin immunoprecipitation (ChIP) assay with this antibody suggested that yhElp3 exerted the transcriptional regulatory function directly through its presence on the SSA3 gene; this might be the reason that it can rescue the delay activation of SSA3 in elp3delta cells.

Objective : To explore the antibacterial activity of epigallocatechin-3-gallate (EGCG) on P. gingivalis and the inhibitory effects on matrix metalloproteinases (MMPs) production induced by P. gingivalis. Methods: The antimicrobial effect of EGCG against planktonic cultures and biofilms of P. gingivalis was evaluated using microplate dilution assays. The microstructural changes in biofilms were studied using scanning electron microscopy (SEM). The inhibitory effect of EGCG on arginine gingipain (Rgp) and lysine gingipain (Kgp) activity of P. gingivalis was evaluated using synthetic chromogenic peptides and fluorogenic substrates. Enzyme-linked immunosorbent assay (ELISA) and qRT-PCR analysis were used to assess MMP-1 and MMP-2 mRNA expression and secretion by human gingival fibroblasts (HGFs) stimulated with P. gingivalis in the presence or absence of EGCG, respectively. Results : The MIC and MBC of EGCG against P. gingivalis were 62.5 μg/mL and 500 μg/mL, respectively. EGCG can not only inhibit the biofilm formation of P. gingivalis but also has a scavenging effect on mature biofilms and can affect their viability. Additionally, 10 μg/mL and 50 μg/mL of EGCG inhibited the proteinase activities of Rgp and Kgp, respectively (P < 0.05). Finally, the mRNA expression and secretion of MMP-1 and MMP-2 by HGFs stimulated by P. gingivalis were significantly inhibited by 50 μg/mL of EGCG (P < 0.05). Conclusion EGCG exhibits antimicrobial effects against P. gingivalis and reduces the expression of MMPs by HGFs.

Objective: To investigate the effect of hypertensive disorder complicating pregnancy (HDCP) on the mortality and early complications of premature infants. Methods: The general clinical data of preterm infants with gestational age 24-36^{+ 6} weeks were collected from the cooperative units in the task group from January 1, 2013 to December 31, 2014.According to the severity of HDCP, the infants were divided into 4 groups: HDCP group, preeclampsia group, eclampsia group and non HDCP group, the mortality and major complications of preterm infants were compared, and the influencing factors were analyzed. Results: The mortality rate of preterm in the HDCP group was significantly higher than that of non HDCP group, and there was statistical significance (χ²=9.970, P=0.019). Eclampsia had a highest fatality rate (4.8%) in the early stage, compared with non HDCP group (2.2%), and the difference was statistically significant.Comparison of HDCP group (1.8%) and eclampsia group (3.2%) suggested that there was no statistically significant difference.The incidence of respiratory distress syndrome (RDS) in preterm in HDCP group was significantly higher than that of non HDCP group, and there was statistical significance (χ²=13.241, P=0.004). Eclampsia group showed the highest incidence (35.4%), compared with non HDCP group (16.2%), the difference was statistically significant, but compared with HDCP group (19.9%), preeclampsia group (17.1%), there was no significant diffe-rence.The incidence of bronchopulmonary dysplasia (BPD) in preterm in HDCP group was significantly higher than that of non HDCP group (χ²=9.592, P=0.022), the highest incidence showed up in eclampsia group (9.7%), compared with non HDCP group (2.0%) and HDCP group (1.7%), the difference was statistically significant.But there was no statistically significant difference, compared with preeclampsia group.As the degree of HDCP aggravated, the incidence of BPD gradually rose.There was no significant impact on necrotizing enterocolitis (NEC), retinopathy of prematurity (ROP), intraventricular hemorrhage (IVH) and sepsis of HDCP (χ²=7.054, 7.214, 0.358, 3.852; P=0.070, 0.065, 0.949, 0.278). Considering the overall outcome of the child, that was, whether the child died or survived, he had at least one complication, and HDCP had an effect on it (χ²=15.697, P=0.001), so the incidence increased while the degree of HDCP rose gradually.After adjusting gestational age, birth weight, sex, way of delivery, placental abruption and front placenta, prenatal hormonal, gestational diabetes, neonatal asphyxia and other factors, the results displayed that HDCP was the factor leading to the death of premature baby (OR=2.159, 95%CI: 1.093-4.266), and comparison between preeclampsia and eclampsia showed no statistical difference (P=0.714, 0.389); HDCP had no significant influence on RDS, BDP, ICH, NEC, ROP and sepsis. Conclusions HDCP leads to increased risk of premature death, but also leads to the increased incidence of RDS and BPD, but it had no obvious effect on NEC, ROP, IVH, sepsis and other complications.
