Objective:To investigate the clinical value of abdominal adipose volume in predicting early tumor recurrence after resection of hepatocellular carcinoma (HCC).Methods:The retrospective case-control study was conducted. The clinicopathological data of 132 HCC patients with tumor diameter ≤5 cm who were admitted to The First Affiliated Hospital of Army Medical University from December 2017 to October 2019 were collected. There were 110 males and 22 females, aged (51±4)years. All patients underwent resection of HCC. Preoperative computer tomography scanning was performed and the visceral and subcutaneous fats of patients were quantified using the Mimics Research 21.0 software. Based on time to postoperative tumor recurrence patients were divided to two categories: early recurrence and non-early recurrence. Observation indicators: (1) consistency analy-sis; (2) analysis of factors influencing early tumor recurrence after resection of HCC and construction of prediction model. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribu-tion were represented as M( Q1,Q3) or M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Consistency analysis was conducted using the intragroup correlation coefficient (ICC) test. Multivariate analysis was performed using the binary Logistic regression model forward method. Independent risk factors influencing early tumor recurrence after resection of HCC were screened. The area under curve (AUC) of receiver operating characteristic (ROC) curve was applied to select the optimal cut-off value to classify high and low risks of recurrence. The Kaplan-Meier method was used to draw survival curve and calculate survival time. The Log-Rank test was used for survival analysis. Results:(1) Consistency analysis. The consistency ICC of abdominal fat parameters of visceral fat volume (VFV), subcutaneous fat volume, visceral fat area, and subcutaneous fat area measured by 2 radiologists were 0.84, 1.00, 0.86, and 0.94, respectively. (2) Analysis of factors influencing early tumor recurr-ence after resection of HCC and construction of prediction model. All 132 patients were followed up after surgery for 662(range, 292-1 111)days. During the follow-up, there were 52 patients with non-early recurrence and 80 patients with early recurrence. Results of multivariate analysis showed that VFV was an independent factor influencing early tumor recurrence after resection of HCC ( odds ratio=4.07, 95% confidence interval as 2.27-7.27, P<0.05). The AUC of ROC curve based on VFV was 0.78 (95% confidence interval as 0.70-0.85), and the sensitivity and specificity were 72.2 % and 77.4 %, respectively. The optimal cut-off value of VFV was 1.255 dm 3, and all 132 patients were divided into the high-risk early postoperative recurrence group of 69 cases with VFV >1.255 dm 3, and the low-risk early postoperative recurrence group of 63 cases with VFV ≤1.255 dm 3. The disease-free survival time of the high-risk early postoperative recurrence group and the low-risk early post-operative recurrence group were 414(193,702)days and 1 047(620,1 219)days, showing a significant difference between them ( χ2=31.17, P<0.05). Conclusions:VFV is an independent factor influen-cing early tumor recurrence of HCC after resection. As a quantitative indicator of abdominal fat, it can predict the prognosis of HCC patients.

A 68-year-old male patient with malignant left lung tumor was treated with gefitinib(250 mg,po,qd)for 29 days.Liver function test results showed AST 310 U·L-1,ALT 493 U·L-1,AKP 100 U·L-1,TBil 18 μmol·L-1,GGT 60 U·L-1,INR 1.81.Several liver function indicators of the patient showed abnormal,which was consistent with the clinical manifestations of moderate liver injury.The liver function index of the patient improved after the doctor adopted the suggestion of clinical pharmacists to protect the liver.Clinical pharmacists made a comprehensive and dynamic assessment of the patient's condition,analyzed the correlation between the patient's liver injury and gefitinib,and judged that the patient's liver injury was likely caused by gefitinib.Clinical pharmacists analyzed the drug use of a blind trial patient,proposed the follow-up treatment plan,and discussed the blind trial drugs,which provided references for clinical safe and rational drug use and had important reference significance.

【Objective】 To estimate the prevalence, associated factors and patterns of multimorbidity of non-communicable diseases among adults in Shaanxi Province so as to provide evidence for the prevention and control of non-communicable diseases. 【Methods】 We used the data of adults aged 18 years and older collected in the baseline survey of Shaanxi Project in the Regional Ethnic Cohort Study in Northwest China. Multinomial logistic regression was used to explore the associated factors for multimorbidity. Exploratory factor analysis was used to extract patterns of multimorbidity. 【Results】 The prevalence of multimorbidity was 10.7% among the 44 442 participants. Age increase, being males, urban residence, and being overweight or obesity were positively associated with multimorbidity. Compared with women, men had a higher risk of multimorbidity. The OR and 95% CI was 1.25 (1.12-1.39). The risk of multimorbidity increased with age among adults. Compared with participants aged 18.0-34.9 years, the ORs and 95% CIs of those aged 35.0-44.9, 45.0-54.9, 55.0-64.9, and ≥65.0 years were 4.73 (3.47-6.46), 15.61 (11.60-21.00), 41.39 (30.76-55.70) and 90.04 (66.58-121.77), respectively. The primary multimorbidity patterns among adults in Shaanxi were cardiovascular-metabolic multimorbidity (5.4%), viscero-articular multimorbidity (1.0%), and respiratory multimorbidity (0.3%). 【Conclusion】 More than one in ten adults in Shaanxi Province had multimorbidity, and the predominant pattern of multimorbidity was cardiovascular-metabolic multimorbidity. The prevention and control of non-communicable diseases should be reinforced in middle-aged and older people, males, people living in the urban, and overweight or obese people. More attention should be paid to the prevention and control of cardiovascular-metabolic diseases.

ObjectiveTo explore the difference of learning and memory function between permanent cerebral ischemia and ischemia-reperfusion rat models by filament-occluded method after three weeks of natural recovery, and to observe the changes of brain structure. MethodsA total of 21 SPF male Sprague-Dawley rats were randomly divided into sham group (n = 7), permanent ischemia group (n = 7) and ischemia-reperfusion group (n = 7). The latter two group underwent left middle cerebral artery occlusion, and the ischemia-reperfusion group was reperfused after 90 minutes of ischemia. All the rats were tested with Morris Water Maze 16 to 22 days after modeling, to record escape latency in the navigation experiment, as well as first latency, platform quadrant swimming time ratio and distance ratio, boundary swimming time ratio and distance ratio, average speed, and the swimming path in the space exploration experiment. On the 22nd day after modeling, four rats with similar Longa scores in each group were scanned by magnetic resonance by diffusion tensor imaging, to measure the fractional anisotropy (FA) of cerebral ischemic cortex, striatum, hippocampus and their corresponding contralateral regions, to calculate ratio of FA (rFA); as well as the volume of infarct (VI) and ratio of VI (rVI). ResultsFor navigation experiment, the escape latency decreased in all the groups with the time (F = 36.202, P < 0.001), but it was not significant for the permanent ischemia group (F = 4.004, P > 0.05). The escape latency was longer in the permanent ischemia group than in the other two groups at each time points (P < 0.05). For space exploration experiment, the boundary time ratio and distance ratio were more in the permanent ischemia group and the ischemia-reperfusion group than in the sham group (P < 0.017), and the first latency was longer in the permanent ischemia group than in the sham group (P < 0.017). The swimming path of ischemia-reperfusion group and sham operation group was better than that of the permanent ischemia group. FA and rFA in left cortex and striatum were less in the permanent ischemia group and the ischemia-reperfusion group than in the sham group (P < 0.05), while FA and rFA of left cortex and FA of left striatum were less in the permanent ischemia group than in the ischemia-reperfusion group (P < 0.05). The VI and rVI were larger in the permanent ischemia group than in the ischemia-reperfusion group (t > 4.185, P < 0.01). FA and rFA of left cortex and striatum correlated with escape latency, boundary time ratio and distance ratio (|r| > 0.498, P < 0.05). The VI and rVI correlated with escape latency and boundary time ratio (|r| > 0.538, P < 0.05). ConclusionCognitive impairment is more severe in the rat model of permanent cerebral ischemia, which may relate to the larger damage of structure of nerve fibers in ischemic cortex and striatum, and larger infarct size.

Chronic obstructive pulmonary disease （COPD） is a common and frequently-occurring disease of the respiratory system， characterized by persistent respiratory symptoms and airflow restriction， which is prone to attack repeatedly and affect patients' quality of life seriously. At present， the combination of bronchodilators and inhaled corticosteroids is commonly used in clinic. Although these drugs can alleviate the symptoms of COPD patients， there are certain limitations of the difficulty in controlling the course of the disease effectively and reversing the decline of patients' lung function. Therefore， searching for safer and more effective therapeutic drugs has become a hot research topic nowadays. Traditional Chinese medicine （TCM） has remarkable curative effects and advantages in the prevention and therapy of COPD recently. Based on the increasing research and application of the active components of TCM in the therapy of COPD， studies on their pharmacodynamic mechanism are also more in depth. More and more studies have found that the active components of TCM can treat COPD patients effectively， and the mechanism involved mainly includes the anti-inflammatory， the antioxidant， and the inhibition of apoptosis. By searching and screening the domestic and foreign literatures on the treatment of COPD with the active components of TCM in recent years， the active components of TCM including flavonoids， terpenoids， phenols and saponins have been studied as the research objects， and their effects in improving the pulmonary function and oxidative stress， relieving inflammation and inhibiting apoptosis are expounded. Besides， the mechanism of action， signaling pathways and index molecules have been emphatically summarized， in order to provide the ideas for the clinical therapy and the basic research of COPD.

Objective:To investigate the efficacy of the Mini-Mental State Scale (MMSE) versus the Montreal Cognitive Assessment Scale (MoCA) in screening cognitive impairment in patients with a lacunar cerebral infarction. Methods:138 eligible patients who received treatment in the Affiliated Hospital of Shanxi Datong University from January 2018 to October 2019 were recruited for this study. They received cognitive function evaluation by the MMSE and MoCA. These patients were grouped according to the median number of age or the median number of years of education. The sensitivity and consistency of the MMSE versus MoCA in screening cognitive impairment in patients with a lacunar cerebral infarction were analyzed using the χ2 test. The total cognitive scores of the MMSE and MoCA, and the scores of each cognitive domain such as memory, execution, visual space, attention, language, and orientation, were compared between groups using multiple linear regression analysis. Results:The sensitivity of MoCA in screening for cognitive impairment in low-age, high-age, low-year-education, and high-year-education groups and the whole population of patients with a lacunar cerebral infarction was 76.5%, 75.7%, 74.2%, 77.8%, 76.1%, respectively, which were significantly higher than those of MMSE (44.1%, 65.7%, 60.6%, 50.0%, 55.1%, χ2 = 12.17, 13.13, 9.33, 15.75, 23.86, all P < 0.01). The Kappa coefficients of low-age, high-age, low-year-education and high-year-education groups were 0.336, 0.391, 0.358, 0.389, and 0.373, respectively, all of which were less than 0.4 (all P < 0.01). These findings suggest that the consistency of the two scales in screening cognitive impairment is poor. The cognitive impairment detection rate by the MMSE was significantly higher in the high-age group than in the low-age group (65.7% vs. 44.1%, χ2 = 6.50, P < 0.05). The total cognitive scores of MMSE and MoCA and the scores of memory, execution, visual space, attention, language, and orientation in patients with a lacunar cerebral infarction were significantly lower in the high-age group or low-year-education group than in the low-age group ( tMMSE = 3.61, 2.49, 3.12, 4.26, 1.70, 3.69, 2.24, all P < 0.01; tMoCA = 3.83, 1.75, 3.28, 3.80, 2.21, 4.08, 2.52, all P < 0.05) or high-year-education group ( tMMSE = -2.87, -2.32, -0.85, -2.54, -0.73, -2.57, -2.96, all P < 0.01; tMoCA = -2.95, -1.12, -3.39, -1.54, -1.52, -3.09, -3.02, all P < 0.05). Conclusion:Combined application of MMSE and MoCA has a high clinical value in screening cognitive impairment in patients with a lacunar cerebral infarction. High-age patients with a lacunar cerebral infarction who receive low-year education have memory, execution, visual space, attention, language, and orientation impairments.

The tubers and roots of Aconitum (Ranunculaceae) are widely used as heart medicine or analgesic agents for the treatment of coronary heart disease, chronic heart failure, rheumatoid arthritis and neuropathic pain since ancient times. As a type of natural products mainly extracted from Aconitum plants, Aconitum alkaloids have complex chemical structures and exert remarkable biological activity, which are mainly responsible for significant effects of Aconitum plants. The present review is to summarize the progress of the pharmacological, toxicological, and pharmacokinetic studies of Aconitum alkaloids, so as to provide evidence for better clinical application. Research data concerning pharmacological, toxicological and pharmacokinetic studies of Aconitum alkaloids were collected from different scientific databases (PubMed, CNKI, Google Scholar, Baidu Scholar, and Web of Science) using the phrase Aconitum alkaloids, as well as generic synonyms. Aconitum alkaloids are both bioactive compounds and toxic ingredients in Aconitum plants. They produce a wide range of pharmacological activities, including protecting the cardiovascular system, nervous system, and immune system and anti-cancer effects. Notably, Aconitum alkaloids also exert strong cardiac toxicity, neurotoxicity and liver toxicity, which are supported by clinical studies. Finally, pharmacokinetic studies indicated that cytochrome P450 proteins (CYPs) and efflux transporters (ETs) are closely related to the low bioavailability of Aconitum alkaloids and play an important role in their metabolism and detoxification in vivo.
