OBJECTIVE To construct an evaluation index system for the effectiveness of cough and wheeze pharmaceutical care clinic （CWPC） among asthma patients， and to provide assessment tools and a theoretical basis for improving the control level of asthma patients and standardizing pharmaceutical care. METHODS Literature analysis and semi-structured interviews were used to establish the evaluation index system for the effectiveness of CWPC among asthma patients. Delphi method was used to conduct two rounds of expert correspondence consultation， and the index weights were determined by the analytic hierarchy process. The reliability and validity of the constructed index system were analyzed by questionnaire. RESULTS Totally 29 experts from three disciplines of medicine， pharmacy and nursing were selected from the third-grade class A hospitals in Henan province. After two rounds of expert correspondence consultation， the effectiveness evaluation index system of CWPC asthma patients （including 9 sub- dimensions， such as lung function， symptoms； 35 measurement items， such as wheezing and respiratory rate） was finally determined from three core dimensions of structure level， function level and literacy management level， and the weight value of each dimension index was determined. The results of the reliability and validity analysis confirmed the scientific rationality of the index system. CONCLUSIONS The constructed CWPC effectiveness evaluation index system for asthma patients has a high degree of recognition， reliability and validity， and can be used as a measurement tool for the effectiveness evaluation of asthma patients.

Objective:To investigate the effectiveness of new cryoprotective agents in preserving and transplanting human adipose tissue.Methods:The adipose tissue samples were obtained from healthy adult females who underwent liposuction at the Department of Plastic Surgery of Peking University Third Hospital from January to March 2022. The adipose tissue samples were centrifuged and then randomly divided into 9 groups. These groups were cryopreserved in liquid nitrogen using different cryoprotective agents [group A, group B, and dimethyl sulfoxide (DMSO) group] and cryopreservation times (1-month, 2-month, and 3-month groups), respectively. The cryoprotective agent formulation in group A was dextrose glycoside 40 (DEX), amino acids, vitamins, and inorganic salts. In group B, the formulation included DMSO and DEX. The ratio of cryoprotective agent in the DMSO group was 10% DMSO, 20% fetal bovine serum (FBS), and 70% DMEM-12. For cryopreservation, 5 ml cryogenic tubes were used with a fat to cryoprotective agent ratio of 3∶2, and each group contains 6 tubes for cryopreservation. After thawing the adipose tissue, HE staining was used to observe the histological morphology. Immunohistochemical staining was employed for the quantitative analysis of lipid droplet-encapsulated protein (Perilipin), and the Perilipin positivity rate was calculated by the ratio of the number of positive cells to the total number of cells. Adipocyte viability was assessed using the CCK-8 method. Thirty-eight healthy, clean nude mice were selected and divided into 3 groups of 12 mice each according to the use of different cryoprotective agents (groups A, B, and DMSO), while the other 2 mice were used as the day 0 control group. The mean fat freezing duration for all groups was 3 months. After nude mice were anesthetized intraperitoneally, 0.9 ml of thawed cryopreserved fat was injected into the dorsum bilaterally. The rate of adipose tissue retention was calculated by MRI scanning and three-dimensional software at 1, 2, and 3 months after transplantation, and compared between the groups. The fat grafts were explanted from the mice after they were sacrificed, and then subjected to histological morphology and quantitative analysis of Perilipin by using HE staining and immunohistochemical staining. GraphPad Prism 8.0 software was used for statistical analysis of the data. The data that conformed to a normal distribution were expressed as Mean ± SD. The overall comparison between multiple groups used analysis of variance for repeated measures. The comparison of data between groups at the same time point used Tukey’s multiple comparison test.Results:The morphology of adipose tissue in different cryoprotective agent groups closely resembled that of normal fresh adipose tissue after being cryopreserved in liquid nitrogen for 1-3 months. The difference in the proportion of Perilipin-stained positive cells in each group was not statistically significant ( P>0.05). The CCK-8 method indicated that the effect of the DMSO group was superior to groups A and B at 1 and 3 months of cryopreservation ( P<0.01), and that the DMSO group and group B were superior to group A at 2 months of cryopreservation ( P<0.01). In the animal experiments, there was no statistically significant difference between the groups in the volume retention rate 1-3 months after cryopreserved fat transplantation ( P>0.05). Additionally, the adipose tissues in each group exhibited varying degrees of localized necrosis accompanied by an inflammatory reaction 1-3 months after transplantation. There was no statistically significant difference in the Perilipin staining positivity between the groups ( P>0.05). Conclusion:The use of new cryoprotective agents for cryopreserving adipose tissue does not show a significant difference compared to the traditional cryoprotective agent. However, it is theoretically safer as it avoids the potential toxic effects of using DMSO or FBS on the human body.

Objective: To explore the association between dietary inflammatory index (DII) and metabolic syndrome (MetS) and its components among children aged 6-14 years in Beijing, so as to provide a reference for preventing MetS. Methods: A cross sectional study was carried out in 2 086 records of 1 832 children from the 2017 and 2019 Nutrition and Health Surveillance in Primary and Secondary school students of Beijing (NHSPSB). Three day consecutive 24 hour dietary recalls combined with weighing household cooking oils and condiments were used to collect dietary intake and calculate DII. MetS was diagnosed according to "Definition and Suggestion on the Metabolic Syndrome of Chinese Children and Adolescent". The Generalized estimating equations (GEEs) models were used to analyze the association between DII and the presence of MetS and its components (abdominal obesity, high triglyceride, low high density lipoprotein cholesterol, hypertension, and hyperglycemia). Results: The mean DII score was (1.64±1.07) for the included children. No significant association was found between DII scores and the likelihood of MetS (per 1 point increment: OR =1.16, 95% CI =0.92-1.48, P >0.05). In terms of the components of MetS, DII scores were positively associated with the odds of high triglyceride (per 1 point increment: OR =1.17, 95% CI =1.01-1.36, P <0.05). There was no statistically significant difference in the association among different age groups ( P >0.05). No significant associations were observed between DII and other MetS components( P >0.05). Conclusion DII scores may not be correlated with the risk of MetS, but proinflammatory diet might increase the risk of high triglyceride. DII score in childhood should be emphasized to identify and prevent MetS as soon as possible.

Objective:To investigate the correlation between cognitive function and living ability of older adult patients living in a mining community.Methods:A total of 180 older adult patients living in a mining community who received treatment during July-October 2019 were included in this study. They were randomly divided into the low-age group (< 68 years old, n = 94) and the high-age group (≥ 68 years old, n = 86). Cognitive function and living ability were evaluated using the Mini-Mental State Examination (MMSE), The Montreal Cognitive Assessment (MoCA), and the Activity of Daily Living Scale (ADL). The relationship between cognitive function and living ability was investigated using hierarchical analysis and Pearson correlation analysis. Results:The proportions of older adult patients with abnormal cognitive function identified by the MMSE and MoCA were 39.4% and 66.0%, respectively in the low-age group, and they were 32.6% and 61.6%, respectively in the high-age group. The MoCA had a greater performance in identifying abnormal cognitive function in each group than the MMSE ( χ2 = 26.69, 10.18, both P < 0.001). There were no significant differences in proportions of older adult patients with abnormal cognitive function identified by the MMSE and MoCA between low-age and high-age groups ( χ2 = 0.90, 0.36, both P > 0.05). The proportion of older adult patients with abnormal living ability was not significantly different between low-age and high-age groups (4.3% vs. 10.5%, χ2 = 2.58, P > 0.05). Compared with patients negative for MMSE items, living ability and instrumental activity of daily living increased by 7.0% and 9.4% in low-age patients positive for MMSE items (both P < 0.05). Compared with patients negative for MoCA items, living ability increased by 3.5% in low-age patients positive for MoCA items ( P < 0.05). Correlation analysis revealed that total scores of MMSE and MoCA were significantly negatively correlated with ADL score ( r = -0.26, -0.27, both P < 0.001) and instrumental activity of daily living score ( r = -0.27, -0.27, P < 0.001). Conclusion:Cognitive function and living ability are correlated in older adult patients living in a mining community. We should pay attention to the screening results of cognitive disorder in older adult patients and improve their living ability by improving their cognitive function.

Objective:To investigate the characteristic of mild cognitive impairment (MCI) in the adults aged 48 years and over in a coal mine community, and to analyze its associated risk factors.Methods:From July to October 2019, a questionnaire survey for basic information was conducted among 180 middle-aged and elderly adults who met the inclusion criteria in the Datong coal mine community. The cognitive function was evaluated by Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). The effects of gender, age, years of education, sleep, living alone, physical exercise, social activities, smoking and drinking status, body mass index and chronic diseases on cognitive level were analyzed by single factor stratification and multiple linear regression.Results:There was no significant difference in the positive rate of MCI screened by MMSE and MoCA in the age groups of 48-<64, 64-<72 and 72-90 (original and corrected P>0.05); The positive rate of MCI in MoCA screening (64.4%, 66.7%, 60.9%) was significantly higher than that in MMSE (35.6%, 45.6%, 28.1%) (all P<0.05); MMSE was positively correlated with MoCA score ( r=0.762, P<0.001). With the increase of age, the scores of memory, execution and visual space detected by MoCA decreased significantly (all P<0.05), while the scores of attention, language and orientation did not change significantly (all P>0.05). Univariate stratification showed that the significant influencing factors of MMSE or MoCA scores were gender, age, years of education and sleep status (all P<0.05). Multiple linear regression analysis showed that gender ( βMMSE=-0.192; βMoCA=-0.140), years of education ( βMMSE=0.209; βMoCA=0.328) and sleep status( βMMSE=-0.162; βMoCA=-0.136) were risk factors affecting MMSE and MoCA scores ( P<0.05). Conclusions:More middle-aged and elderly adults with MCI might be observed in a coal mine community, and the main characteristics of MCI are impaired memory, executive function and visual space. To prevent and reduce the occurrence of dementia, early interventions of MCI should be carried out among the adults with female, old age, low years of education and poor sleep quality.

ObjectiveTo investigate the serological markers associated with posthepatectomy recurrence in patients with hepatocellular carcinoma, and to establish a prognostic model to evaluate whether palliative hepatectomy is suitable for such patients. MethodsA total of 111 patients with hepatocellular carcinoma who underwent hepatectomy in the Affiliated Cancer Hospital of Zhengzhou University from February 2009 to July 2013 and received follow-up were enrolled. Basic clinical data were collected and the patients were divided into recurrence group and non-recurrence group according to whether recurrence was observed during follow-up. The t-test was used for comparison of normally distributed continuous data between two groups and the Wilcoxon rank sum test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. Survival curves were plotted using the Kaplan-Meier method, and survival differences were analyzed using the log-rank test. A Cox regression analysis was used to perform univariate and multivariate analyses, and the area under the ROC curve (AUC) was used to evaluate prediction efficiency. ResultsThe Kaplan-Meier survival curves showed that the patients with low alpha-fetoprotein (AFP), alkaline phosphatase, gamma-glutamyl transpeptidase (GGT), and fibrinogen and high CXCL13 had a longer median time to recurrence (P＜0.05). AFP (hazard ratio ［HR］［95%CI］=1.69(1.03~2.79), P=0.039), GGT (HR［95%CI］=1.89(1.14~3.14), P=0.014), and CXCL13 (HR［95%CI］=0.54(0.33~0.89), P=0.015) were independent factors associated with posthepatectomy recurrence. The prognostic index PI=0.526×AFP+0.637×GGT-0.616×CXCL13 established based on these factors had an AUC of 0.87, a sensitivity of 93.75%, and a specificity of 63.64% in predicting recurrence within 0-3 months after palliative hepatectomy, with a significant reduction in prediction efficiency for recurrence within 0-6 months (AUC=0.68) or a longer period of time. The recurrence prediction efficiency of this model for palliative hepatectomy was significantly higher than that for radical resection. ConclusionThe prognostic model established based on CXCL13, AFP, and GGT can be used to evaluate the risk of early recurrence after palliative hepatectomy and thus helps clinicians to make diagnosis and treatment decisions based on patients’ benefits.

Liver injury caused by viral and non-viral factors is an important stage of chronic liver disease, and the pathogenesis of liver injury is still a research hotspot. With the deepening of the research on gut microbiota, substantial evidence indicates that gut microbiota participates in the development and progression of liver injury, and it has been confirmed that Akkermansia muciniphila (Akk) has a beneficial effect against liver injury. This article summarizes the role and potential mechanism of Akk in immune-mediated liver injury, alcoholic liver disease, and nonalcoholic fatty liver disease. It is believed that Akk may provide new directions and choices for the prevention and treatment of liver injury.

Objective: To establish and evaluate diagnostic efficacy and applicability of serum Golgi protein (GP) 73 based non-invasive diagnostic model with other conventional serological indicators for compensated stage hepatitis B cirrhosis. Methods: 666 cases with chronic hepatitis B (CHB) who had visited to the Fifth Medical Center of People’s Liberation Army General Hospital from January 2010 to December 2017 were selected as the study subjects, and were classified according to compensated stage cirrhosis into clinical and pathological diagnosis group based on whether or not the liver histological examination was performed. A diagnostic model of compensated stage hepatitis B cirrhosis in the clinical diagnosis group was established. The current clinically used diagnostic model of liver cirrhosis, aspartate aminotransferase/platelet ratio index (APRI), fibrosis index (FIB)-4 and liver stiffness measurement (LSM) were compared. Eventually, the diagnostic model was verified step by step by pathological diagnosis group. Results: The area under the receiver operating characteristic curve (AUC) of GP73 and APRI, FIB-4, and LSM for cirrhosis patients in the clinical diagnosis group were 0.842, 0.857, 0.864, and 0.832, respectively. The diagnostic efficiency of the four indicators were of similar (P value > 0.05). A diagnostic model of compensated stage hepatitis B cirrhosis (GAPA) using logistic regression analysis was established: LogitP = 1/ [1 + exp (1.614-0.054 × GP73-0.045 × Age + 0.030 × PLT-0.015 × ALP)]. The AUC of the model was as high as 0.940 and the optimal cut-off value were 0.41. The corresponding diagnostic sensitivity and specificity were 0.92 and 0.82, respectively. The diagnostic efficiency was better than that of APRI, FIB-4, LSM and GP73 alone (P < 0.05). The AUC of GAPA was 0.877 in the pathological diagnosis group, which was similar to the diagnostic efficacy of LSM (0.891) and FIB-4 (0.847) (P > 0.1), but still superior to that of APRI (0.811) and GP73 alone (0.780) (P < 0.001). Conclusion GAPA, a diagnostic model for compensated stage hepatitis B cirrhosis established in this study, has a good diagnostic efficacy in both the clinical and pathological diagnosis group, and has certain auxiliary diagnostic value in the areas where resources are relatively scarce or where LSM has not been developed.

Background: Patients with acute gouty arthritis experienc severe pain and often have concomitant limited joint movement. High-dose intake of anti-inflammatory analgesics often results in adverse reactions, such as nausea, vomiting, and diarrhea, and might increase the risk of gastrointestinal bleeding. In order to reduce the adverse reactions by oral intake, local use of externally useddrugs with the same active ingredients as the oral intake is an option in clinical practice. However, externally useddrugs take effect slowly and efficacy to reduce painful feelingis unsatisfactory. Therefore, it is demanding to develop a safe and effective treatment plan. In this regard, researchers have put up a hypothesis. The skin of the human body has a dense stratum corneum, which is difficult for externally used drugs to penetrate effectively; if the keratin barrier of the skin around affected joints can be broken without further damaging the skin, externally applied drugs may safely and effectively alleviate the local symptoms of acute gouty arthritis. The nano plum blossom needle is made of a modern new material. The needle body is thin and the diameter of the needle tip is only 300 nm. The needle is used clinically to break through the keratin barrier of the human skin and promote the absorption of external medicine. Therefore, this trial was designed to preliminarily evaluate the safety and effectiveness of using the nano plum blossom needle for the introduction of diclofenac diethylamine emulgel in the treatment of acute gouty arthritis. Methods: A randomized controlled trial including 83 patients with acute gouty arthritis was conducted, who was assigned to three groups, the intervention group, control group 1, and control group 2 in a ratio of 2:2:1, respectively. The nano plum blossom needle was used for the introduction of diclofenac diethylamine emulgel in the intervention group; the nano plum blossom needle was used as a placebo along with the local use of diclofenac diethylamine emulgel in control group 1; and the nano plum blossom needle was used alone in control group 2. The treatments were applied once a day until the pain was completely relieved and the course of treatment lasted up to 7 days. The primary outcome measurement was the visual analog scale for evaluating the degree of pain. The secondary outcome indicators included scoring of the symptoms and signs with comprehensive consideration of the joint skin color, local tenderness, and degree of joint motion, the time and dose of emergency medication usage during trial, and adverse events. Discussion: This trial couldprovide preliminary evidence for evidence-based practice of using nano plum blossom needle transdermal drug delivery technology for diclofenac diethylamine emulgel for the treatment of acute gouty arthritis, and provide a reference for sample size calculation and experimental design of future clinical trials verifying the effectiveness and safety of such a technical scheme in a larger target population. Registration information This study has been registered in the China Clinical Trial Registry Centerwith the registration code of ChiCTR-IOR-17012154.
