RESUMO
OBJECTIVE: To investigate the anti-inflammatory effect of electroacupuncture (EA) on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), also known as chronic nonbacterial prostatitis (CNP), and explore its underlying mechanism. METHODS: A CNP rat was established by surgical castration combined with 17-ß estradiol injection in male Sprague-Dawley rats for thirty consecutive days. The CNP rats received EA treatment once a day for eight days. Chronic pelvic pain was evaluated by mechanical withdrawal threshold measurement. The histological change was assessed by hematoxylin-eosin staining. The inflammatory cytokines in prostates were determined by enzyme-linked immunosorbent assays. The expressions of toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), inhibitors of kappa-B alpha (IκBα), and nuclear factor-kappa B (NF-κB) were detected by Western blotting. The nuclear translocation of NF-κB and the location of TLR4 were observed with immunofluorescence staining. RESULTS: The results showed that EA decreased the prostate index, upregulated the mechanical withdrawal threshold, restored the histomorphology of the prostate, reduced the inflammatory factor levels, inhibited NF-κB p65 nuclear translocation, and downregulated the expression levels of critical proteins involved in the TLR4/NF-κB signaling pathway in prostates. CONCLUSIONS: Our findings suggested that EA could relieve pelvic pain and attenuate prostatic inflammation in estradiol-induced CNP rats. The underlying mechanism may be related to the inhibition of the TLR4/NF-κB signaling pathway.

Objective:To investigate the relationship between the expressions of serum trans thyroxine protein (TTR) , retinol binding protein 4 (RBP4) and metabolic syndrome of pregnancy (GMS) .Methods:A total of 103 patients with GMS from May. 2017 to Dec. 2019 were selected as the observation group, in addition, 100 healthy pregnant women with single pregnancy and no complications were selected as control group. Before pregnancy, the height and weight were detected. After the diagnosis of GMS, serum markers and blood pressure were detected. The levels of total cholesterol (TC) , triglyceride (TG) , low density lipoprotein cholesterol (LDL-C) , high density lipoprotein cholesterol (HDL-C) and fasting blood glucose (FBG) were detected by Hitachi 7600 automatic biochemical analyzer, and the expression levels of TTR and RBP4 in serum were detected by enzyme-linked immunosorbent assay (ELISA) . Receiver operating characteristic (ROC) curve was drawn to evaluate the diagnostic value of TTR and RBP4 in GMS. Multivariate Logistic regression model was used to analyze the influencing factors of GMS in pregnant women.Results:There was no significant difference in age or gestational weeks between the two groups ( P>0.05) . Compared with those in the control group, the levels of BMI, TC, TG, LDL-C, FBG, systolic blood pressure, diastolic blood pressure, serum TTR and RBP4 expression levels were higher in the observation group before pregnancy ( P<0.05) , while HDL-C was lower ( P<0.05) . The area under the curve (AUC) of TTR and RBP4 alone or combination in the diagnosis of GMS was 0.797, 0.816 and 0.898, respectively. The cut-off value of TTR was 284.91 mg/L, and the sensitivity and specificity were 63.10% and 89.00%, respectively. The cut-off value of RBP4 was 17.89 mg/L, and the sensitivity and specificity were 69.90% and 87.00%, respectively. The sensitivity and specificity of the combined diagnosis were 83.50% and 84.00% respectively. Multivariate Logistic regression analysis showed that high level of TTR and high level of RBP4 were independent risk factors of GMS in pregnant women ( P<0.05) . Conclusions:The expression levels of serum TTR and RBP4 in GMS patients are high, and they have certain diagnostic value for GMS. They are independent risk factors of GMS in pregnant women, which may provide new ideas for the early diagnosis and prevention of GMS.
RESUMO
Objective:To analyze the clinical features of post-pancreaticoduodenectomy hemorrhage, and explore effective and practical nursing strategies.Methods:Clinical data of 62 patients with post-pancreaticoduodenectomy hemorrhage from Jan 2014 to Dec 2019 in the First Affiliated Hospital of Naval Medical University were retrospectively analyzed. The bleeding time, location, vital signs, accompanying symptoms and surgical treatment measures and clinical outcomes were analyzed.Results:Among the 62 cases, early (within 24 h) hemorrhage occurred in 19/62 patients (30.6%), and late hemorrhage occurred in 43/62 patients (69.4%). 36/62 patients (58.1%) had arterial bleeding; And 43/62 patients (69.4%) had abdominal hemorrhage. Grade C hemorrhage occurred in 32/62 patients (51.6%). Sentinel hemorrhage occurred in 8/62 patients (12.9%). The manifestation of hemorrhage in 42 patients was bloody fluid from abdominal drainage tube (67.7%). Hemorrhage occurred in 23 patients with pancreatic fistula(37.1%), 12 patients with abdominal infection and other complications (19.4%). Shock symptoms occurred in 41 cases (66.1%) with postoperative hemorrhage. Pancreaticoduodenectomy hemorrhage were early detected in 0.3 h and last detected in 869 h, with a median time of 192.00 (14.63, 297.00) h. 30/62 cases (48.4%) of hemorrhage patients occurred 1 hour before and after nursing shift. When hemorrhage was found, emergency treatments such as blood transfusion to maintain blood volume ( n=47, 75.8%), hemostasis ( n=35, 56.5%) and vasoactive drugs to increase blood pressure ( n=32, 51.6%) were usually given immediately. 31/62 patients (50.0%) underwent emergency secondary surgery within 4 h of hemorrhage, and 45/62 patients (72.6%) were cured by emergency surgical treatment. A written treatment pre-plan for surgical nurses was established. Conclusions:Surgical nurses should be familiar with the clinical manifestations of post-pancreaticoduodenectomy hemorrhage, and improve the alarming ability of identifying the complications of post-operative hemorrhage. The establishment of an emergency pre-plan for surgical nurses could help to treat such patients timely and effectively.
RESUMO
Objective To evaluate the design and effectiveness of electronic nursing records. Methods The integrated and structural electronic nursing records of SICU were designed based on the HIS system and monitors in cooperation with the company from January,2015. The traditional paper-based records were totally replaced by electronic records which had been adjusted and tested for six months. Cost of time and revise were compared between traditional and electronic records ten days before the replacement. Three months later, satisfaction survey and user experiencefor the electronic records was conducted. Results The cost of time on electronic records (43 ± 11) min were much lower than traditional records(30±10) min (t=7.132, P=0.002). The revise on electronic records(20.48%, 86/420) were relatively lower than traditional records (10.24%, 43/420) (χ2=16.934, P=0.001).After using electronic nursing records the satisfaction was increased significantly from 90%(36/40) to 100%(40/40) (U=7.112, P<0.01); Nurses reflect electronic nursing records significantly better than the traditional records, according to record trend diagram of vital signs and corresponding processing, nurse managements can analysis and evaluate nursing quality, also finding original nursing records just patient information, so the nurses will be strict with their recording and processing objectively, timely. Conclusion The electronic nursing records can reflect the changes of patients' actual condition more accurately and comprehensively, and the advantage about standard, convenience and time-saving is beneficial to improve nurse work efficiency. This record system can provide the dynamical situation and evaluate the quality of nursing directly for nursing managers and doctors, also make it possible for permanent data retention.

RESUMO
BACKGROUND: Procedural burn pain is the most intense acute pain and most likely type of burn injury pain to be undertreated due to the physician's fear of the adverse effect of analgesia and lack of anesthetist present. At our institution, in most of the cases, local burn detersion and debridement were performed at the ward level without any analgesics. This article describes a study designed to test the analgesia effect of a fixed nitrous oxide/oxygen mixture on burn dressing pain. METHODS/DESIGN: The experiment was carried out in three centers. The patients were given a number from 1 to 240. A randomization list was produced by a statistician according to our preliminary study. Due to the severity of the pain suffered, ethically it was decided to help as many as possible, so patients given the letters A, B or C were treated using a canister with the appropriate letter containing preprepared nitrous oxide/oxygen mixture (NOOM). Those with D were given oxygen only, from an identical-looking canister labeled D. Neither patients, nor doctors, nor nurses, nor data collector knew what was in each canister, thus they were all blind. The nursing officer who implemented the intervention handed the doctors envelopes containing the patients' name and allocation of A, B, C or D. Thus, patients receiving NOOM or oxygen were in the ratio 3:1. Parameters, including pain severity, blood pressure, heart rate, digital oxygen saturation and the Chinese version of the burn specific pain anxiety scale (C-BSPAS), were taken before, during and after dressing for each group. A video and audio record was taken individually for later communication coding and outcome analysis. Rescue analgesic was recorded. DISCUSSION: Based on the findings from our previous qualitative study that physician's reluctance to order narcotic analgesia is due to its adverse effect and from our pilot experiment, this study aims to test the hypothesis that a fixed nitrous oxide/oxygen mixture will promote better burn dressing pain alleviation and outcomes. Analyses will focus on the effects of the experimental intervention on pain severity during dressing (primary outcomes); physiological parameters, C-BSPAS and acceptance of both health care professionals and patients (secondary outcomes). If this model of analgesia for burn pain management implemented by nurses proves successful, it could potentially be implemented widely in hospital and prehospital settings and improve patients' satisfaction and quality of life. TRIAL REGISTRATION: (Clinical Trials Identifier: CHICTR-TRC11001690).

In this study, a putative esterase, designated EstMY, was isolated from an activated sludge metagenomic library. The lipolytic gene was subcloned and expressed in Escherichia coli BL21 using the pET expression system. The gene estMY contained a 1,083 bp open reading frame (ORF) encoding a polypeptide of 360 amino acids with a molecular mass of 38 kDa. Sequence analysis indicated that it showed 71% and 52% amino acid identity to esterase/lipase from marine metagenome (ACL67845) and Burkholderia ubonensis Bu (ZP_02382719), respectively; and several conserved regions were identified, including the putative active site, GDSAG, a catalytic triad (Ser203, Asp301, and His327) and a HGGG conserved motif (starting from His133). The EstMY was determined to hydrolyse p-nitrophenyl (NP) esters of fatty acids with short chain lengths (≤C8). This EstMY exhibited the highest activity at 35°C and pH 8.5 respectively, by hydrolysis of p-NP caprylate. It also exhibited the same level of activity over wide temperature and pH spectra and in the presence of metal ions or detergents. The high level of stability of esterase EstMY with unique substrate specificities makes it highly valuable for downstream biotechnological applications.

We studied the effects of several medicinal insects on biosynthesis of polysaccharides from Ganoderma lucidum in submerged culture. The results showed that the medicinal insect, Catharsius molossus at 5 g/L significantly promoted the biosynthesis of intracellular polysaccharides (IPS) and extracellular polysaccharides (EPS) of G. lucidum, and compared with control, IPS and EPS yields markedly enhanced from (1.93 +/- 0.09) g/L to (2.41 +/- 0.12) g/L and (520.3 +/- 20.2) mg/L to (608.9 +/- 20.2) mg/L, respectively (P < 0.05). Both IPS and EPS consisted of five kinds of components, and IPS-1 and EPS-1 were the major components of IPS and EPS, respectively. Further separation studies showed that IPS-1 was made up of three single compounds, while EPS-1 was made up of two single compounds. There were no new components in both IPS and EPS obtained from G lucidum in submerged culture by the addition of the insect, C. molossus, suggesting the biosynthetic pathways of the major components of IPS and EPS had not been changed.
