OBJECTIVE To predict potential quality markers(Q-markers) in Yinhua Miyanling tablets based on fingerprinting and network pharmacology methods. METHODS HPLC fingerprints of 13 batches of Yinhua Miyanling tablets were established, and the similarity analysis was carried out using the "Chromatographic Fingerprint Evaluation System for Traditional Chinese Medicine" to identify the common peaks and attribute them. The fingerprints of Yinhua Miyanling tablets were investigated using chemometrics, cluster analysis, principal component analysis and orthogonal partial least squares discriminant analysis in combination with SPSS 26.0 and SIMCA 14.1 software to identify the major signature components responsible for the differences. The network pharmacology was used to screen and analyze the targets and pathways of Yinhua Miyanling tablets, construct a "drug-component-target-pathway" network diagram, and predict the Q-Marker and core targets of Yinhua Miyanling tablets. RESULTS HPLC fingerprint of Yinhua Miyanling tablets was established, and 27 common peaks including chlorogenic acid, mangostin, wild baicalin, lignocerin and quercetin were identified. Chemical pattern recognition analysis screened five components as differential markers for Yinhua Miyanling tablets. Five active ingredients, 20 core targets and 20 key pathways were screened by network pharmacology, showing that all five active ingredients could be used as potential Q-Markers. CONCLUSION The method is stable, accurate and feasible for screening five chemical components as potential Q-Markers for Yinhua Miyanling tablets. It provides a reference for the overall control of the quality of Yinhua Miyanling tablets, and also lays the foundation for further research on the mechanism of action of Yinhua Miyanling tablets.

Aristolochic acid (AA), extracted from Aristolochiaceae plants, plays an essential role in traditional herbal medicines and is used for different diseases. However, AA has been found to be nephrotoxic and is known to cause aristolochic acid nephropathy (AAN).AA-induced acute kidney injury (AKI) is a syndrome in AAN with a high morbidity that manifests mitochondrial damage as a key part of its pathological progression. Melatonin primarily serves as a mitochondria-targeted antioxidant. However, its mitochondrial protective role in AA-induced AKI is barely reported. In this study, mice were administrated 2.5 mg/kg AA to induce AKI. Melatonin reduced the increase in Upro and Scr and attenuated the necrosis and atrophy of renal proximal tubules in mice exposed to AA. Melatonin suppressed ROS generation, MDA levels and iNOS expression and increased SOD activities in vivo and in vitro. Intriguingly, the in vivo study revealed that melatonin decreased mitochondrial fragmentation in renal proximal tubular cells and increased ATP levels in kidney tissues in response to AA. In vitro, melatonin restored the mitochondrial membrane potential (MMP) in NRK-52E and HK-2 cells and led to an elevation in ATP levels. Confocal immunofluorescence data showed that puncta containing Mito-tracker and GFP-LC3A/B were reduced, thereby impeding the mitophagy of tubular epithelial cells. Furthermore, melatonin decreased LC3A/B-II expression and increased p62 expression. The apoptosis of tubular epithelial cells induced by AA was decreased. Therefore, our findings revealed that melatonin could prevent AA-induced AKI by attenuating mitochondrial damage, which may provide a potential therapeutic method for renal AA toxicity.

Objective:To discuss the influence of mindfulness-based stress reduction plus micro-class education on the complications and knowledge mastery rate in surgical patients with diabetes mellitus.Methods:A total of 105 patients, diagnosed as diabetes mellitus complicated with appendicitis in the Affiliated Hospital of Chengde Medical College were selected from January 2019 to January 2020. They were hospitalized for laparoscopic appendectomy and were randomly divided into the control group ( n = 52) and the study group ( n = 53) in accordance with the random number table. The patients in the control group were given routine nursing care, and the patients in the study group were given mindfulness decompression therapy combined with micro-classroom education. The blood glucose control and psychological emotion of the two groups before and after operation, and the postoperative complications and the mastery rate of disease knowledge of the two groups were compared. Results:There was no significant difference in blood glucose indexes between the two groups at baseline ( P>0.05); FBG, HbA1c and other indicators in the two groups were improved during operation and 24h after operation, but FBG (7.38±0.54) mmol/L, HbA1c (6.39±0.21)% and FBG (6.90±0.52) mmol/L and HbA1c (6.10±0.39)% in the study group were lower than those in the control group [(8.16±1.21) mmol/L, (7.53±1.05)%, (7.60±0.57) mmol/L, (6.50±0.41)%], the difference was statistically significant ( t value was 6.789-13.264, P < 0.05); there was no significant difference in SAS and SDS scores between the two groups at baseline ( P > 0.05), until discharge, the SAS and SDS scores of the treatment group were 35.81±5.49 and 42.08±4.91 respectively, which were significantly lower than those of the control group (42.21±5.53, 6.51±4.72) respectively, compared with the corresponding scale scores of the control group, the difference between the two groups after treatment was statistically significant ( t value was 5.386, 4.265, P < 0.05). Compared with 17.31% (9/52) of the control group, the incidence of complications in the study group decreased to 5.66% (3/53), there was significant difference ( χ2 value was 6.789, P < 0.05). The qualified rate of disease knowledge mastery in the study group (98.11%,52/53) was significantly higher than that in the control group (86.53%, 45/52), and the difference was significant ( χ2 value was 5.062, P < 0.05). Conclusion:The mindfulness-based stress reduction plus micro-class education can effectively control the laparoscopic appendectomy patients blood glucose, stabilize the mental emotions, increase the illness knowledge mastery degree, keep in good mood, reduce the postoperative complications and promote the fast recovery.

Objective:To implement an intervention with community-dwelling middle-aged and elderly people through a new science promotion approach, and to evaluate changes in the level of bone health awareness.Methods:From April 2017 to June 2017, 200 community-dwelling middle-aged and elderly people aged 50 years and over were randomly included.They were divided into the intervention group receiving a new science promotion intervention(n=100, with 50 males and 50 females)and the control group(n=100, with 50 males and 50 females). Baseline and follow-up assessments of bone health awareness were performed before and after the one-year intervention.A questionnaire survey on preferences for different types of science promotion articles in WeChat accounts was conducted.Differences in scores for intervention effects before and after intervention were compared between the two groups.Potential influencing factors for the scale score were examined by a multi-factor analysis.Results:After one year of intervention, scores for intervention effects were higher in the intervention group than in the control group( P<0.001). In the intervention group, scores were higher after intervention than before intervention( P<0.001). In the control group, scores after follow-up were slightly higher than those at baseline(29.4±11.4 vs.27.9±10.1, P<0.001). The increase in scores before and after intervention was greater in the intervention group than in the control group( P<0.001). Baseline score, group designation, history of drinking and diabetes impacted the scores in middle-aged and elderly women, while other factors did not.Most middle-aged and older people preferred texts illustrated with pictures, and older people were more receptive to videos. Conclusions:The new science promotion method is beneficial to bone health management, can improve bone health awareness in middle-aged and elderly people.

Objective: To investigate the influencing factors of fertility outcome after laparoscopic conservative surgery for tubal pregnancy. Methods: From October 2010 to October 2016, 253 cases of tubal pregnancy treated by laparoscopic conservative surgery in General Hospital of Jizhong energy Fengfeng Group Hospital were analyzed retrospectively.All patients were followed up from 24 to 36 months after operation to observe the intrauterine pregnancy.Logistic regression was used to analyze the influencing factors of intrauterine pregnancy. Results: After 24-36 months follow-up, the patients were not contraception and pregnant under the guidance of doctors.Among the 253 cases, 182 (71.1%) were intrauterine pregnancy, 37 (14.6%) were ectopic pregnancy, and 34 (13.4%) were not pregnant.The results of logistic regression showed that high level of hCG, severe pelvic adhesions, obstruction of fallopian tube and history of ectopic pregnancy were the risk factors of intrauterine pregnancy (OR (95%CI) 1.982 (1.075-3.149), 2.410 (1.279-5.069), 2.485 (1.071-3.594), 5.071 (1.094-9.081), P<0.05 or P<0.01). Conclusion The reproductive outcome of laparoscopic conservative surgery for tubal pregnancy is influenced by many factors.The high level of hCG in preoperative blood, severe pelvic adhesions, obstruction of tubal and ectopic pregnancy history are the risk factors of postoperative pregnancy.

OBJECTIVE: To explore genetic mutation types and their correlation with clinical phenotypes in Uighur patients with aortic disease in Kashgar (Xinjiang Uighur Autonomous Region, China). METHODS: We examined 37 pathogenic genes in 19 Uighur families with aortic diseases including Marfan syndrome from Kashgar using next generation sequencing, and the results were confirmed by Sanger sequence in the first relatives. RESULTS: This study included 19 families with aortic diseases, in whom a total of 23 variants were identified, and 11 (57.89%) probands had one or more variants. Among them, definite pathogenic mutation was detected in one patient (5.26%), variants of uncertain significance (VUS) were found in 8 (42.11%), and benign/likely benign variants were detected in 7 (36.84%). The 23 variants identified included one (5.26%) pathogenic variant, 14 (60.87%) VUS, and 8 (34.78%) benign/likely benign variants. The 14 VUS were analyzed by prediction with SIFT and Polyphen2 HDIV, which identified 6 (42.86%) variants as deleterious/possibly damaging; all the 8 benign/likely benign variants were predicted to be deleterious/possibly damaging. CONCLUSIONS We detected 23 genetic variants in the 19 Uighur families with aortic diseases, and 22 of these variants remain to be verified by more patient data in future studies.

OBJECTIVE: To investigate the prevalence and influencing factors of work-related musculoskeletal disorders(WMSDs) among workers in a cement plant. METHODS: A total of 196 workers in a cement plant were selected as study subjects using a judgment sampling method. A revised Musculoskeletal Injury Questionnaire was used to investigate the occurrence of WMSDs in workers in the past year. RESULTS: The detection rate of WMSDs in different parts of the body of workers in the cement plant was 18.4%-32.1%. The detection rates of WMSDs in all parts of the body from high to low was as follows: shoulder(32.1%), neck(30.6%), upper back(24.0%), ankle/foot(24.0%), lower back(23.5%), hip/thigh(22.4%), wrist/hand(21.4%), elbow(18.4%), and knee(18.4%). Multivariate logistic regression analysis results showed that keeping the neck in the same posture for a long time was a risk factor for neck WMSDs [odds ratio(OR)=2.29, P<0.05). Frequent turning around was a risk factor for WMSDs on the neck and lower back(waist)(OR were 3.06 and 3.32, P<0.05). Maintaining the same posture for a long time on the back was a risk factor for shoulder and upper back WMSDs(OR were 3.22 and 2.34, P<0.05). Hard work was a risk factor for shoulder and upper back WMSDs(OR were 2.60 and 2.58, P<0.05). Driving a vehicle was a risk factor for lower back(waist) and ankle/foot WMSDs(OR were 2.54 and 3.17, P<0.05). Carrying objects heavier than 20 kilograms and frequent overtime working were risk factors for ankle/foot WMSDs(OR were 3.03 and 2.54, P<0.05). CONCLUSION: The most frequent parts of the body having WMSDs in the cement production workers are shoulders and necks. Occupational factors(turning around or keeping the same posture of neck and back) are risk factors of WMSDs on shoulder and neck.

The biodiversity of the mycobiome, an important component of the oral microbial community, and the roles of fungal-bacterial and fungal-immune system interactions in the pathogenesis of oral lichen planus (OLP) remain largely uncharacterized. In this study, we sequenced the salivary mycobiome and bacteriome associated with OLP. First, we described the dysbiosis of the microbiome in OLP patients, which exhibits lower levels of fungi and higher levels of bacteria. Significantly higher abundances of the fungi Candida and Aspergillus in patients with reticular OLP and of Alternaria and Sclerotiniaceae_unidentified in patients with erosive OLP were observed compared to the healthy controls. Aspergillus was identified as an "OLP-associated" fungus because of its detection at a higher frequency than in the healthy controls. Second, the co-occurrence patterns of the salivary mycobiome-bacteriome demonstrated negative associations between specific fungal and bacterial taxa identified in the healthy controls, which diminished in the reticular OLP group and even became positive in the erosive OLP group. Moreover, the oral cavities of OLP patients were colonized by dysbiotic oral flora with lower ecological network complexity and decreased fungal-Firmicutes and increased fungal-Bacteroidetes sub-networks. Third, several keystone fungal genera (Bovista, Erysiphe, Psathyrella, etc.) demonstrated significant correlations with clinical scores and IL-17 levels. Thus, we established that fungal dysbiosis is associated with the aggravation of OLP. Fungal dysbiosis could alter the salivary bacteriome or may reflect a direct effect of host immunity, which participates in OLP pathogenesis.

Objective? To construct a risk assessment scale for patients with acute myocardial infarction (AMI) and reperfusion arrhythmia after percutaneous coronary intervention (PCI) by Delphi expert consultation at home and abroad. Methods? From 1st January 2017 to 31st December 2017, we preliminarily drew up risk factors related to patients with AMI and reperfusion arrhythmia after PCI by retrieving and analyzing the heart surgery related risk assessment scale at home and abroad; and we confirmed the weight of risk factors by two rounds of expert consultation on scientific nature, suitability and operability of risk factors with the method of Delphi method and the expert evaluation method. Results? The recovery rates of questionnaire were 90% and 95% respectively in two rounds of expert consultation, and the authority coefficient was 0.89 and 0.93. The risk assessment scale constructed for patients with AMI and reperfusion arrhythmia after PCI included 3 first-level risk factors, 13 second-level risk factors. Among weight of risk factors by two rounds of expert consultation, the variation coefficients were all less than 0.2, and the coordination coefficient ranged from 0.20 to 0.34. Conclusions? All the experts participating in the investigation are positive with the high consistency of expert opinion, good coordination, professional representativeness and high authority. The constructed risk assessment scale can effectively assess the risk of AMI patients after PCI, reduce the processing time of reperfusion arrhythmia, enhance the ability of nurses to predict the reperfusion arrhythmia of those patients so as to early decrease the incidence of reperfusion risk.
