This study aimed at analyzing the medication regularity based on differentiation in traditional Chinese medicine (TCM) for losing weight using text mining technique.All the references over losing weight were retrieved in CNKI,Wangfang Database,VIP Database and Pubmed.The drugs from the references were classified in accordance with drug property,drug flavor,channel tropism and drug efficacy.Frequency and constituent ratio of a single drug in TCM prescriptions for losing weight were put into analysis using chi square test and factor analysis to find out the medication regularity.It was found that the properties of TCM drugs in the prescriptions contained both cold and warm,while the flavors of the drugs involved pungent,sweet and light.The channel tropism of the drugs mainly belonged to spleen meridian,liver meridian,stomach meridian and lung meridian.They were mostly tonic,relieving,blood-activating,qi regulating,inhibiting-damp and antipyretic drugs.Through factor analysis we found that the common formula compatibilities were concluded as:cassia seed,lotus leaf,hawthorn,salvia miltiorrhiza,polygonum cuspidatum and radix polygonum multiflorum;capillary artemisia,epimedium herb,stephania tetrandra and ligusticum wallichii;dried tangerine peel,pinellia ternata and poria cocos;plantain seed,pericarpium arecae and selfheal;paeonia lactiflora,angelica sinensis,scutellaria baicalensis and ligusticum wallichii;poria cocos,cassia twig,atractylodes and glycyrrhiza;immature bitter orange and bark of magnolia;radix bupleuri,lycium chinensis and jujube;Chinese yam and coix seed;and astragalus,pueraria lobata and polygonatum.In conclusion,formula compatibility mainly combined syndrome differentiation with disease differentiation for the treatment of obesity in clinic,using the drugs belonging to liver meridian,spleen meridian,stomach meridian and lung meridian with the flavors of sweet,bitterness or pungent and the nature of both warm and cold.

AIM: To study the relationship between Chlamydia pneumoniae (Cpn) and spontaneous brain bleeding. METHODS: The IgG and IgM antibody titers to Cpn in peripheral blood from 9 patients of spontaneous brain bleeding were detected by microimmunofluorescence antibody technique (MIF). The Cpn DNA of arteries in brain bleeding region from these cases was detected by polymerase chain reaction (PCR). The Cpn major outer membrane protein (MOMP) expression of arteries in brain bleeding region from these cases were tested by Western blot. RESULTS: All the geometric average titer to IgG antibody (190 3?3 2) and the positive rate of IgG antibody (85 2%) and IgM antibody (30 8%) were significantly higher in spontaneous brain bleeding patients than those (48 1?2 0, 48 1% and 4 8%) in control ( P

Objective : To examine the diagnostic and prognostic value of long non-coding RNA (lncRNA) JPX in mesothelioma, so as to provide insights into diagnosis and prognosis of mesothelioma. Methods: Patients with clinically definitive diagnosis of mesothelioma from 2015 to 2019 that were sampled from asbestos processing plants in Zhejiang Province from 2015 to 2019 were recruited in the mesothelioma group, while healthy residents without asbestos exposure or asbestos-related diseases in the same area served as controls. Participants' demographics, pathologic diagnosis and imaging features were collected, and the expression of blood lncRNA JPX was detected using lncRNA microarrays. The diagnostic value of lncRNA JPX for mesothelioma was evaluated using the receiver operating characteristic (ROC) curve, and the correlation between lncRNA JPX expression and prognosis was examined among mesothelioma patients using survival analysis. Results: There were 17 subjects in the mesothelioma group, with a mean age of (65.71±8.36) years, and 34 subjects in the controls, with a mean age of (64.24±8.70) years. LncRNA microarray detected significantly high lncRNA JPX expression in mesothelioma patients, and higher blood lncRNA JPX expression was detected in the mesothelioma group than in the control group [median (interquartile range), 1.10 (1.31) vs. 0.89 (0.54); t'=-2.300, P=0.034]. The area under the ROC curve was 0.673 (95%CI: 0.507-0.839, P=0.046), and if the cutoff was 1.759, the sensitivity and specificity were 35.3% and 100.0%, respectively. Survival analysis showed no significant difference in the survival rate of mesothelioma patients between the high lncRNA JPX expression group and the low expression group (χ2=0.212, P=0.645). Conclusions LncRNA JPX overexpression is detected in the blood of patients with mesothelioma, and lncRNA JPX expression presents a diagnostic value for mesothelioma; however, it shows little prognostic value for mesothelioma.

Objective : To investigate the status of occupational stress and analyze its influencing factors among frontline employees working in a chemical fiber manufacturing enterprise, so as to provide insights into the development of occupational stress interventions. Methods : The frontline employees working in a chemical fiber manufacturing enterprise were selected as the study subjects using a cluster sampling method in October 2018. The status of occupational stress was investigated using the Chinese version of the effort-reward imbalance ( ERI ) questionnaire. The influencing factors for occupational stress were identified using a multivariable logistic regression model. Results : A total of 1 780 questionnaires were sent out, and 1 115 valid ones ( 62.64% ) were recovered. Among the 1 115 respondents, there were 427 men ( 38.30% ) and 688 women ( 61.70% ), and 71.22% were at ages of 21 to 39 years. There were 561 respondents with < 1 year of service ( 50.31% ), and the longest length of service was 11 years. In addition, there were 1 069 respondents ( 95.87% ) exposed to high noise, and 346 respondents ( 31.03% ) were diagnosed at a high occupational-stress state and 769 ( 68.97% ) at a low state. Multivariable logistic regression analysis identified 5 years or longer of service ( OR=1.540, 95%CI: 1.057-2.245 ) and exposure to high noise ( OR=1.917, 95%CI: 1.004-3.659 ) as risk factors for occupational stress among frontline employees in the chemical fiber manufacturing enterprise. Conclusions There are 31.03% of frontline employees at a high occupational-stress state in the chemical fiber manufacturing enterprise, and a high occupational-stress state is associated with exposure to high noise and 5 years or longer of service.

Objective:To construct a perioperative venous thrombosis prevention program for patients with spinal surgery based on evidence-based nursing, and to discuss its application effect.Methods:Using the convenient sampling method, a total of 90 patients with spinal surgery who were admitted to Jinhua People's Hospital from June 2019 to June 2020 were selected as the control group and received routine nursing management.

Postoperative prothrombin time, thrombin time and activated partial thromboplastin time all showed a trend of decreasing first and then increasing and the levels of fibrinogen and D-dimer showed a trend of increasing first and then decreasing, and the differences were statistically significant ( P<0.05) . Regardless of the time factor, postoperative prothrombin time, thrombin time, and activated partial thromboplastin time in the observation group were longer than those in the control group, and the levels of fibrinogen and D-dimer were lower than those in the control group, and the differences were statistically significant ( P<0.05) . The blood flow velocity of common femoral vein, popliteal vein, and iliac vein in the two groups were interacted, and the difference was statistically significant ( Finteraction=6.257, 3.281, 7.697; all P<0.05) . After operation, the blood flow velocity of common femoral vein, popliteal vein and iliac vein all showed a trend of first decreasing and then increasing, and the differences were statistically significant ( P<0.05) . Regardless of the time factor, the postoperative blood flow rates of the common femoral vein, popliteal vein and iliac vein in the observation group were higher than those in the control group, and the differences were statistically significant ( P<0.05) . The incidence of venous thromboembolism in the observation group was 1.11%, which was lower than 6.67% in the control group, and the difference was statistically significant ( P<0.05) . Conclusions:The perioperative venous thrombosis prevention and management plan based on evidence-based nursing can provide individualized nursing intervention for spinal surgery patients according to different thrombosis risks, which can improve patients' coagulation and lower extremity venous function and effectively reduce the risk of thrombosis.
