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 analyze the survival of patients with malignant mesothelioma, so as to provide insights into the management of malignant mesothelioma. Methods : Totally 36 patients with malignant mesothelioma admitted to Cixi Third People’s Hospital from October 2012 to January 2021 were enrolled, and the demographic features, exposure to asbestos, and diagnosis and treatment were retrospectively reviewed. The survival rate and median survival time were calculated with the life-table method, and the factors affecting the survival rate of malignant mesothelioma were identified using the Kaplan-Meier estimate and log-rank test. Results : The 36 patients with malignant mesothelioma included 6 men ( 16.67% ) and 30 women ( 83.33% ), and had a median age of 61 ( interquartile range, 14 ) years. There were 30 cases with pleural malignant mesothelioma ( 83.33% ) and 6 cases with peritoneal malignant mesothelioma ( 16.67% ), 32 cases ( 88.89% ) with a history of occupational exposure to asbestos, and 26 cases ( 72.22% ) receiving palliative treatment. The 1-, 2- and 3-year cumulative survival rates were 30%, 15% and 3%, respectively, and the median survival time was 0.71 years. In addition, there were no significant differences in the survival period among patients with malignant mesothelioma in terms of gender, age, route of asbestos exposure, duration of asbestos exposure, pathogenic site and treatment regimens ( P>0.05 ). Conclusion The 36 patients with malignant mesothelioma had a median survival period of 0.71 years, and no association was found between the survival period and asbestos exposure or pathogenic site.

Objective:To investigate the neuroprotective effect of long-term prophylactic use of buphthalein on mice with permanent distal middle cerebral artery occlusion and its relationship with the nuclear factor erysid 2 related factor 2 (Nrf2) pathway.Methods:Nrf2 + /+ wild-type and Nrf2 -/- knockout mice were randomly divided into control group (equal volume vegetable oil), low-dose butylphthalide group (20 mg/kg) and high-dose butylphthalide group (60 mg/kg), with 6 mice in each group. The drug was administered once a day by gavage for 1 month, and then a permanent middle cerebral artery occlusion model was induced by electrocoagulation. After the model was made, the drug was continued and the mice were sacrificed on the 10 th day. The modified Longa grading scale and the rotating rod test were used to evaluate neurological deficits on the 3 rd and 10 th day after the model was made. After the mice were sacrificed, the cerebral infarct volume was measured by triphenyltetrazolium chloride staining. The brain water content was measured by dry and wet weight method. The expression of Nrf2 pathway related factors, including Nrf2, heme oxygenase 1 (HO-1) and NAD(P)H quinone oxidoreductase 1 (NQO1) were measured by quantitative real-time PCR and Western blotting. Results:On the 10 th day after modeling, compared with the Nrf2 -/- control group, the neurological deficit was significantly milder, the volume of cerebral infarction and brain water content were significantly smaller, and the mRNA and protein levels of Nrf2, HO-1 and NQO1 were significantly higher in the Nrf2 + /+ control group, and the differences were statistically significant ( P<0.05). For Nrf2 + /+ mice, compared with the control group, the cerebral infarct volume was significantly reduced ( P<0.05), the brain water content was significantly reduced ( P<0.05), and the neurological function recovery was significantly better ( P<0.05), and the levels of Nrf2, HO-1, and NQO1 mRNA and protein were significantly higher in the high-dose butylphthalide group (all P<0.05). For Nrf2 -/- mice, there were no significant differences in neurological function, cerebral infarction group volume, brain water content, Nrf2, HO-1, NQO1 mRNA and protein levels among the groups. Conclusion:Long-term butylphthalide pretreatment can significantly improve the neurological function, reduce cerebral infarction volume, reduce brain water content, and increase Nrf2, HO-1, NQO1 mRNA and protein expression levels in mice with permanent distal middle cerebral artery occlusion, suggesting butylphthalide may play a neuroprotective effect by up-regulating the expression of Nrf2 gene and its downstream antioxidant stress factors HO-1 and NQO1.

OBJECTIVE: To explore the correlation between the genotypes and metabolic markers and microstructure of bones in children with Gitelman syndrome (GS). METHODS: For 15 children with GS and 10 healthy individuals, baseline data and bone metabolic markers including parathyroid hormone, alkaline phosphatase, osteocalcin, N-terminal propeptide of type I procollagen, beta isomer of the C-terminal telopeptide of type I collagen and 25-hydroxyvitamin D, high-resolution peripheral quantitative computed tomography indicators (volumetric bone mineral density, bone microstructure indicators) were collected. Genetic testing was carried out to determine their genotypes. RESULTS: The volumetric bone mineral density, bone geometry and bone microstructure parameters of the GS group were better than those of the healthy controls (P<0.05). Variants of the SLC12A3 gene were identified in 9 of the 15 patients but none of the 10 healthy controls. CONCLUSION The phenotype of GS children is influenced by the interaction of genetic variants, though the phenotype associated with high frequency mutations showed no specificity. There is also a correlation between their genotype and the bone microstructure.

OBJECTIVE： To investigate the role of clinical pharmacists in the individual anticoagulation of warfarin for the patients with lower extremity venous thrombosis （LEVT） and pulmonary arterial thromboembolism （PATE）. METHODS： Clinical pharmacists participated in individual anticoagulation of warfarin for the patients with LEVT and PATE. It was suggested to detect the gene type of the patient. According to the results of gene test [cytochrome P450 （CYP）2C9*1*1 and vitamin K epoxide reductase complex subunit Ⅰ] and the dose recommended by FDA based on the patient’s gene， the initial dose of warfarin （3.125 mg，once a day） was determined according to the patient’s living habits， height and body mass. Then the maintenance dose of warfarin （the maintenance dose of warfarin was 2.5 mg and 3.125 mg， once a day， alternately taken every other day） was calculated according to the warfarin maintenance dose prediction formula established by Warfarin Pharmaeogenetics Consortium. Pharmaceutical monitoring was conducted， such as INR， prothrombin time and bleeding event monitering. RESULTS： Physicians adopted the suggestion of clinical pharmacists. The maintenance dose of warfarin was 2.5 mg and 3.125 mg， once a day， alternately taken every other day. It was suggested to give Flucloxacillin sodium injection which had less influence on warfarin. The patient recovered well and was discharged. CONCLUSIONS： Based on pharmacogenomics， clinical pharmacists participate in the formulation of individualized anticoagulant regimens for patients， which promote TNR ralue of patients， reduce the risk of early postoperative thromboembolism， and further ensure the safety of drug use in patients.

Objective To investigate status of the intravenous use of antibiotics in outpatients and emergency patients of a tertiary first-class hospital, and provide a reference for developing management measures in next step. Methods By a retrospective method,all the prescriptions using antibiotics by intravenous administration in outpatients and emergency department patients from a tertiary first-class hospital in 2013 were extracted from the hospital information system. The categories of antimicrobial agents,proportion of intravenous use of antimicrobial drugs,ranking of the antibiotic consumption sum and defined daily dose,and the top 10 clinical departments or wards intravenously using antimicrobial drugs were chosen to analyze. The data in 2014 were extracted as a comparison. Results Outpatients and emergency department patients respectively used 8 categories 31 kinds and 8 categories 30 kinds of intravenous antimicrobial drugs, with high consumption of cephalosporins and restricted antimicrobials such as sodium cefoxitin.Intravenous use of antimicrobial drug prescription proportion in emergency department is higher than that in outpatient department. Conclusion After intervention in 2014, antibiotic consumption is effectively controlled as compared that in 2013. But management should be strengthened and appropriate interventions should be taken to ensure the use of intravenous antibiotics in a safe,effective and economical manner.

Objective To investigate the optimal timing of surgical treatment for multi-drug resistance patients,discuss the clinical effect of surgery with chemotherapy treatment for muhi-drug resistant tuberculosis,and obtain more evidence for further optimizing surgical treatment strategy for such patients.Methods 100 cases who were multi-drug resistant and who received treatment in our hospital from July 2003 to June 2010 were included in this retrospective study.Among them,50 (observation group) received pulmonary lobectomy followed by anti-tuberculosis chemotherapy for 12 to 24 months,and the others (control group) only received anti-tuberculosis regimens although they had indications for pulmonary lobectomy.All patients in both groups were followed up for 12 to 24 months.Therapeutic effects and post-operational events were compared statistically in the observation group patients according to their duration of disease.Results Results At the end of follow-up,the cure rate,illness exacerbation rate and mortality were 36.0％ (18/50),16.0％ (8/50) and 26.0％ (13/50) respectively in the control group,whereas those in the observation group were 80.0％ (40/50),2.0％ (1/50) and 4.0％ (2/50) respectively.Resistanee to new anti-tuberculosis drugs appeared in 3 cases (6％) in the control group,while there was no new resistance in the observation group.The cure rate and complication rate were 96.30％ and 3.70％ respectively for patients whose duration of illness was less than 2 years,whereas those were 47.8％ and 43.5％ respectively for cases whose duration of illness was more than 2 years.Bronchopleural fistula,hemorrhage,pyothorax and pulmonary atelectasis were main postoperative complications,from which 11 cases recovered and 2 died,the death caused by choking of big haemoptysisand and multiple organs failure.Conclusion The therapeutic effects of surgical treatment plus anti-tuberculosis chemotherapy were better than chemotherapy alone.Pulmonary lobectomy could result in better response if done at the earlier stages of illness.Complications of operations were acceptable.

OBJECTIVETo assess the anti-nociception and anti-inflammation pharmacodynamics of Asarum heterotropoides var. mandshuricum and A. sieboldii.

METHODBoth the writhing test and hot plate test were conducted to assess the anti-nociceptive effect of Asarum and Xylene-induced mouse ear edema was conducted to assess the anti-inflammatory effect of Asarum.

RESULTTwelve samples of A. heterotropoides var. mandshuricum and A. sieboldii from different producing areas showed anti-nociceptive and anti-inflammatory effects. Specifically, 27% to 61% of the seven samples of A. heterotropoides var. mandshuricum showed anti-nociceptive effect and while 34% to 48% of A. sieboldi showed anti-nociceptive effect. The inflammatory inhibition rate of A. heterotropoides var. mandshuricum produced in six producing areas (38%-57%) is higher than that of A. heterotropoides var. mandshuricum produced in five producing areas (34%-48%). The same kind of Asarum produced in different areas showed significant differences. A. heterotropoides var. mandshuricum produced in Jilin province (38%-57%) showed better anti-nociceptive effect than sample produced in Heilongjiang province (34%) in writhing test. A. heterotropoides var. mandshuricum produced in Heilongjiang (43%) province showed a better anti-nociceptive effect than samples produced in Liaoning province (29%-36%) in hot plate test. A. sieboldii produced in Shaanxi province (47%-49%) showed a better anti-nociceptive effect than samples produced in Hubei province (40%) in writhing test. A. sieboldii produced in Shaanxi province (45%-59%) showed better anti-nociceptive effect than samples produced in Chongqing (40%) in hot plate test. A. heterotropoides var. mandshuricum produced in Jilin province (51%-63%) showed better anti-inflammatory effect than samples produced in Heilongjiang province (50%). In totality, the results from analysis of geoherbalism showed that famous-region A. heterotropoides var. mandshuricum and A. sieboldii had a better anti-nociception effect than Asarum produced in other producing areas, famous-region A. heterotropoides var. mandshuricum had a better effect than those produced in other producing areas in anti-inflammation. But famous-region A. sieboldii showed no obvious difference from those produced in other producing areas in anti-inflammation.

CONCLUSIONAll samples of Asarum showed anti-nociceptive and anti-inflammatory effects, but with significant differences among Asarum produced in different areas, indicating the eoherbalism to some extent.
