ABSTRACT
ObjectiveTo observe the clinical efficacy of herb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription in the treatment of infertility induced by idiopathic asthenozoospermia （iAZS） with kidney-Yang deficiency and collateral obstruction syndrome and its effect on sperm DNA damage and superoxide dismutase （SOD） in the seminal plasma. MethodsA total of 112 eligible patients who met the inclusion criteria were randomly divided into an observation group （56 cases） and a control group （56 cases）. The patients in the observation group were treated with herb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription，while those in the control group received levocarnitine oral liquid. The primary observation indicators included spouse pregnancy rate，progressive motility （PR），and total sperm motility，and the secondary observation indicators included sperm DNA fragmentation index （DFI），SOD in the seminal plasma， and improvement of TCM syndromes. The treatment cycle was 12 weeks. Before and after treatment，the PR，total sperm motility，sperm DFI，SOD in the seminal plasma， and TCM syndrome scores were recorded. The patients were followed up for 12 weeks and the pregnancy status of spouses within 24 weeks （half a year） was recorded. The clinical efficacy of the two groups was evaluated. ResultThe pregnancy rate of spouses in the observation group was 15.69% （8/51）， higher than 3.85% （2/52） in the control group （χ2=4.118，P<0.05）. The total effective rate of the observation group was 88.24%（45/51）， superior to 69.23% （36/52）in the control group （Z=-3.402，P<0.01）. After treatment， PR， total sperm motility，sperm DFI， SOD in the seminal plasma， and TCM syndromes of the two groups were improved compared with those before treatment （P<0.05）， and the observation group was superior to the control group （P<0.05）. ConclusionHerb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription in the treatment of iAZS-induced infertility patients with kidney-Yang deficiency and collateral obstruction syndrome can increase PR，total sperm motility， and SOD level in the seminal plasma， reduce sperm DFI，improve the TCM symptoms of patients， and improve the pregnancy rate of spouses. The mechanism may be attributed to the fact that this treatment can increase the SOD level in the seminal plasma of patients，enhance the body's antioxidant function，protect sperm from oxidative stress damage，and reduce sperm DFI.
ABSTRACT
Objective To investigate the curative effect of ultra early enteral nutrition (EN) supplemented with probiotics in patients with severe acute pancreatitis (SAP).Methods Seventy-five SAP cases admitted in Second People's Hospital of Nantong from December 2014 to June 2018 were enrolled and assigned into 24 h group (who received EN & probiotics at 24 h,n =25),72 h group (who received EN & probiotics at 72 h,n =25) and the control group (who received EN & probiotics on day 7,n =25).After admission,the levels of PCT,hs-CRP and endotoxin on day 1,4 and 8 were detected.APACHE Ⅱ score on day 3 after admission,complication rate,infection rate,hospitalization duration and mortality were recorded.Results On day 1 after admission,serum PCT,hs-CRP and endotoxin concentrations among three groups were of no significant differences.On day 4 after admission,the serum concentrations of PCT and edotoxin in 24 h group were significantly lower than those in 72 h group and the control group [(3.12 ± 1.45) μg/L vs (5.26±1.52),(6.07 ± l.59) μg/L;(0.24 ± 0.02) EU/ml vs (0.35 ±0.03),(0.46±0.04) EU/ml].The serum hs-CRP in 24 h group was significantly lower than that of the control group [(20.71 ±4.89) μg/L vs (28.37 ± 4.64) μg/L],and the difference was statistically significant (P ＜ O.05).The serum concentrations of hs-CRP in 24 h group and 72 h group was of no significant difference.On day 7 after admission,the serum concentrations of PCT,hs-CRP and endotoxin in 24 h group were significantly lower than those in 72 h group and the control group (P ＜0.05);the serum concentrations of PCT,hs-CRP and endotoxin in 72 h group were significantly lower than those of the control group,and all the differences were statistically significant (all P ＜ 0.05).The score of APACHE Ⅱ (day 3 after admission) [(15.1 ± 1.8)],complication rate (52％),infection rate (8％),length of stay [(19.7 ± 5.3) d] in 24 h group were all significantly lower than those of 72h group [(17.0 ± 2.0),72％,32％,(25.4 ± 6.8) d] and control group [(18.3 ±2.6),84％,44％,(38.7 ± 12.6) d],and all the differences were statistically significant (all P ＜0.05).Conclusions Ultra EN supplemented with probiotics in treating the patients with SAP could significantly reduce the level of serum PCT,hs-CRP and endotoxin,decrease complication rate and mortality,and shorten the time of hospitalization.
ABSTRACT
Objective To investigate the training expectations and training strategies of orthopedic clinical specialist nurses (OCSN).Methods Totally 5 020 orthopedic nurses from 342 hospitals from 30 provinces and cities were selected bv convenience sampling.Participants were investigated hy WeChat platform with self-designed questionnaire.Results A total of 4 982 effective questionnaires were collected.Among investigated nurses,13.7％ of them received orthopedic specialist nurses training;91.4％ believed that training should be carried out.Qualifications should be:college degree and above,senior nurse and above,at least 3 ～5 years of nursing experience,1～3 years of nursing experience in orthopedic department.For curriculum,public courses expected to be arranged were communieation skills,nursing teaching,nursing management,and nursing research;expected professional courses were functional exercises,pain management,extremity injury nursing,common treatment techniques in orthopedic department,traction nursing,and position nursing.It was suggested that training was divided into subspecialties and off-duty;classroom teaching,teaching rounds,case discussion and experience exchange were expected training methods;"theory-practice-theory-practice" was most preferable traiuing mode.The preferred teachers were orthopedic doctors,orthopedic head nurses,orthopedic specialist nurses,and senior orthopedic nurses.The length of training was expected to be three months,time for clinical practice should be greater than or equal to theoretical teaching,and the practice bases should be tertiary hospitals.Evaluation should be performed before completion,recertification could be later than completion,and the interval time of recertification should be within 5 years.Conclusion Training needs of orthopedic nurses for OCSN are strong.Training expectations(contents,length,modes and teachers) of orthopedic nurses should be considered when designing systematic training program on OCSN.
ABSTRACT
Background and purpose: Renal cell carcinoma is the most common form of kidney cancer, characterized by lack of early symptoms and high malignancy. This study aimed to establish orthotopic nude mice models of human renal cell carcinoma with high success rate and good repeatability. Methods: The four types of methods which were adopted to establish the orthotopic models of renal cell carcinoma were orthotopic injection of 786-0 and ACHN cell suspensions, orthotopic injection of primary cell suspensions obtained from the subcutaneous tumor tissues, renal subcutis orthotopic implantation into renal capsule and surgical subcutis orthotopic implantation into renal fascia. To gain insights into the tumorigenicity and the growth of transplantation tumors, the imageological examination (PET/CT), histological examination (H-E staining, immunohistochemistry staining) and biochemical analysis of blood were carried out. Results: In terms of the subcutaneous transplantation of human renal cell carcinoma models in nude mice, tumorigenic rate of ACHN cells (90%) was higher than that of 786-0 cells (30%). The tumorigenic incidences of 786-0 cell suspensions orthotopic injection, ACHN cell suspensions orthotopic injection, ACHN subcutis cellular suspensions orthotopic injection, ACHN subcutis orthotopic implantation into renal capsule and renal fascia were 33%, 80%, 90%, 100% and 20%, respectively. ACHN subcutis orthotopic implantation into renal capsule was the most effective approach. Imageological and histological results accorded with poorly differentiated renal cell carcinoma. Conclusion: Four orthotopic nude mice models of human renal cell carcinoma were successfully established. Among these methods, ACHN subcutis orthotopic implantation into renal capsule is the most effective approach, which provides an ideal model for the research on biological behavior of human renal cell carcinoma and its treatment.
