ABSTRACT
Objective:To explore the regulation effect and possible mechanism of transcutaneous electrical acustimulation (TEA) on the improvement of gastrointestinal motility and inflammation in patients with acute pancreatitis (AP).Methods:A randomized, single-blinded, sham-controlled study was performed. A total of 62 AP patients were randomly divided into the TEA group ( n=31) and sham-TEA group ( n=31), on the basis of regular treatment, who received TEA treatment at Neiguan (PC6) and Zusanli (ST36) or sham-TEA treatment at corresponding pseudo stimulation acupoints for 2 days. Abdominal distension score, time to first defecation, gastric slow wave, heart rate variability (low frequency and high frequency, reflecting sympathetic and vagal activity, respectively), serum level of tumor tecrosis factor (TNF)-α, plasma levels of motilin, ghrelin and vasoactive intestinal peptide(VIP) tested by enzyme linked immunosorbent assay were compared before and after the treatment. Wilcoxon rank test, Mann-Whitney U test, t-test and two factor repeated measurement analysis of variance were used for statistical analysis. Results:After the treatment, abdominal distension score of TEA group was lower than that of sham-TEA group(1 (0 to 2) vs.5(3 to 6)) and time to first defecation was earlier than that of sham-TEA group((55.00±24.27) h vs.(67.95±23.84) h), the percentage of normal gastric slow wave was higher than that of sham-TEA group((57.42±11.16)% vs. (40.92±8.52)%), and the differences were statistically significant ( Z=-4.95、 t=-2.12、 F=61.53, all P<0.05). After the treatment, the serum level of TNF-α of TEA group was significantly lower than that of sham-TEA group((4.27±1.28) ng/L vs.(6.19±2.03) ng/L), and the difference was statistically significant ( F=28.65, P<0.05). The ratio of post/pre-treatment of low frequency heart rate variability of the TEA group was significantly lower than that of sham-TEA group, however, the result of high frequency was opposite (0.87±0.18 vs.1.14±0.16, 1.19±0.18 vs.0.96±0.13), and the differences were statistically significant ( t=-6.22 and 5.74, both P<0.05). After the treatment, the plasma level of ghrelin of TEA group was higher than that of sham-TEA group ((2.02±0.62) μg/L vs. (0.93±0.49) μg/L), the VIP level was lower than of sham-TEA group ((30.58±12.20) μg/L vs.(44.35±29.52) μg/L), and the differences were statistically significant ( F=59.22 and 5.50, both P<0.05). However, there was no significant difference in motilin levels between two groups ((24.57±9.58) ng/L vs. (22.75±9.58) ng/L, P>0.05). Conclusion:TEA treatment can improve gastrointestinal motility and inhibit the inflammation in early AP, which may be related with the regulation of autonomic function, gastrointestinal hormone ghrelin and VIP.
ABSTRACT
Objective:To investigate the effect of individualized and generalized dual track continuous health education on patients with endometrial cancer after operation.Methods:From January 2019 to January 2020, 96 patients with endometrial cancer in the Second Affiliated Hospital of Henan University of traditional Chinese Medicine were enrolled. They were all treated with surgery. According to the random number table method, they were divided into the control group and the study group, with 48 cases in each group. However, during the whole study period, some patients were affected by various factors, and the final number of patients in the study group was 45 cases (dual track continuous health education combined with individualization and generalization) and 45 cases in the control group(routine continuous health education). Before the intervention and 3 months after the intervention, the obstetrics and Gynecology nurses who had received relevant training adopted self-made health knowledge awareness questionnaire, self-care ability assessment scale (ESCA), Medical Coping Style Questionnaire (MCMQ) and simple quality of life scale (SF-36).The patients' mastery of disease knowledge,self-care ability,coping style and quality of life were evaluated.Results::After the intervention,the awareness of health knowledge was 42.23±2.58 in the study group and 35.71±3.26 in the control group, and the difference was statistically significant ( t value was 4.508, P<0.01). After the intervention, the self-care skills, self responsibility, self-concept, health knowledge level and total score of the study group were 9.45±1.58, 11.82±1.63, 61.12±6.52, 10.56±1.33 and 31.83±2.21 respectively, while those of the control group were 5.34±0.75, 7.85±0.92, 68.23±6.45, 6.35±0.94 and 19.54±1.26 respectively, and the difference between the two groups was statistically significant ( t value was 11.025-16.444, P<0.05). After the intervention, the scores of facing,avoiding and yielding in the study group were 19.39±3.29, 10.58±2.40, 9.20±3.12 respectively, and those in the control group were 15.97±3.77, 14.56±3.00, 13.02±2.50 respectively, with significant difference between the two groups( t value was 4.459, 6.762, 6.220, P<0.01). After the intervention, the scores of physiological function,physical pain,social function,mental health,emotional function,vitality and general health in the study group were 80.23±8.12, 22.19±2.63, 44.98±4.25, 76.25±7.64, 69.58±6.23, 70.05±7.22 and 78.31±7.52 respectively, while those in the control group were 59.63±5.14, 52.37±5.38, 41.16±4.73, 57.28±5.36, 55.25±5.27, 46.89±4.52 and 48.96±4.37 respectively, the difference between the two groups was statistically significant( t value was 3.630-11.870, P<0.05).

ABSTRACT
OBJECTIVE： To optimize the integrated processing technology for “precise decoction pieces” of Helianthus annuus. METHODS： The contents of total flavonoids and total protein in H. annuus were determined by UV spectrophotometry with rutin and bovine serum albumin as control. Refering to Chinese Pharmacopoeia， the contents of water soluble extract， dilute ethanol extracts and ethyl acetate extract were determined. Based on the different needs such as maintaining quality consistency with the original medicinal materials， preference for anti-gout treatment， preference for liver calming and pain relief， using the contents of total flavonoids， total protein and 3 kinds of polar extract as indexes， gray correlation method was used to optimize the integrated processing technology of 3 kinds of “precise decoction pieces” of H. annuus. RESULTS： Gray correlation analysis showed that the ideal sample sequence of decoction pieces in massive shape dried at 60 ℃ with the original medicinal materials and decoction pieces with preference use of liver calming and pain relief was the most relevant； the ideal sample sequence of ideal sample sequence of decoction pieces in massive shape dried in the shade with decoction pieces with clinical application preference of anti-gout therapy was the most relevant. CONCLUSIONS： Different integrated processing technology for “precise decoction pieces” of H. annuus can be adopted for different needs. If it is necessary to keep the quality consistent with the original medicinal materials or to prepare H. annuus decoction pieces for liver calming and pain relieving， medicinal material can be cut into massive shape and dried at 60 ℃； if it is necessary to prepare H. annuus decoction pieces for anti-gout treatment， cutting into massive shape and drying in the shade can be adopted.
ABSTRACT
Heart rate variability (HRV) is an important point to judge a person's state in modern medicine. This paper is aimed to research a person's fatigue level connected with vagal nerve based on the HRV using the improved Welch method. The process of this method is that it firstly uses a time window function on the signal to be processed, then sets the length of time according to the requirement, and finally makes frequency domain analysis. Compared with classical periodogram method, the variance and consistency of the present method have been improved. We can set time span freely using this method (at present, the time of international standard to measure HRV is 5 minutes). This paper analyses the HRV's characteristics of fatigue crowd based on the database provided by Physio-Net. We therefore draw the conclusion that the accuracy of Welch analyzing HRV combining with appropriate window function has been improved enormously, and when the person changes to fatigue, the vagal activity is diminished and sympathetic activity is raised.

ABSTRACT
Objective To explore the immunogenicity of recombinant chimeric 6Aβ15-T including the Aβ1-15 epitope and a T-helper epitope formulated with different adjuvants and to evaluate its feasibility as a candidate vaccine for Alzheimer disease (AD).Methods The recombinant chimeric antigen 6Aβ15-T formulated with Al adjuvant, Freund′s adjuvant or MF59 adjuvant was administered to two strains of mice .The 6Aβ15-T-immunized group without adjuvants ( Mock) and non-immunized group (Control) were included in this study as control groups .The specific antibody and cellular immune response of the chimeric antigen were evaluated .Results In BALB/c strain mice, three types of adjuvants could substan-tially boost the immunogenicity of chimeric antigen 6Aβ15-T and produce a high level of specific-Aβ(β-amyloid) antibod-ies.In C57BL/6 strain mice, the existence of adjuvants enhanced the immune response of 6Aβ15-T antigen, but the mice in Mock group also produced a strong antibody response .In two strains of mice, prevalence of anti-AβIgG1, which was an indicator of Th2 polarization, was observed in the 6Aβ15-T-immunized mice.Additionally, the Al adjuvant induced a high-er level of IgG1 antibody titers, and the ratio of IgG1/IgG2a was the largest.As expected, the 6Aβ15-T antigen formulated with or without adjuvants induced PADRE-specific, but not Aβ42-specific T cellular immune response .Conclusion The 6Aβ15-T antigens formulated with different types of adjuvants could induce strong Th 2-polarized Aβ42-specific antibody re-sponses without activating self-reactive Aβ42-specific T cells in two strains of mice .The results suggested that the recombi-nant chimeric antigen 6Aβ15-T is a good candidate vaccine for AD .
ABSTRACT
With the development of business of manned spaceflight, the body damage of astronauts on the space en-vironment has received growing concern. Weight loss is the most important cause of various diseases, and the weightlessness muscle atrophy is one of urgent problems to be solved in aerospace medicine. Although there is no concept of weightlessness or weightlessness muscle atrophy in the theory of traditional Chinese medicine (TCM), TCM can grasp the pathogenesis of complex diseases, and provide important theoretical references for the prevention and management of weightlessness diseases, especially weightlessness muscle atrophy. In this paper, TCM Cognition of weightlessness and the pathogenesis of weightlessness muscle atrophy was studied by the sight of TCM theory of qi hoisting. The discussion was made from aspects of circulation of qi and blood, zang-fu function. This work is wished to be beneficial to apply the TCM theory in aerospace medicine.
ABSTRACT
Objective To analyze the distribution features of injury regions and severty of patients with traumatic brain injury ( TBI ) associated with muhiple injuries and discuss the influence of different injury regions and severity on their outcome.Methods Retrospective analysis was performed for clinical data of 1026 patients treated from August,2007 to August,2010. Results The majority of TBI patients associated with multiple injuries were young people( accounting for 78.07％ of the total injuries),among whom the males outnumbered females in proportion of 3.62:1,and the multiple injuries were mainly characterized by chest injuries (accounting for 46.69％ of multiple injuries).Spearman analysis indicated that Glasgow Outcome Scale (GOS) was correlated with Glasgow Coma Scale (GCS)score,age,maxillofacial region injuries,chest and abdomen injuries (P ＜ 0.05 ).Logistic regression analysis manifested that age,GCS score,and lung injury were the independent risk factors of high mortality in TBI patients associated with multiple injuries. Conclusion Low GCS scores,old age and severe lung injuries indicate a high mortality and morbidity,while injuries in extremities and pelvis have no significant influence on the outcome.
