This paper summarizes the observation and nursing of patients with postoperative complications following percuta-neous transhepatic cholangogrphic drainage(PTCD) and biliary tract stent implantation for malignant obstructive jaundice. A-mong thirty-two patients,eight had postoperative complications,including two with biliary tract hemorrhage,four with biliary tract infection,one with pneumothorax and one with bile leakage. All the thirty-two patients recovered well in clinical symptoms and quality of life. To attach importance to psychological nursing and postoperative health education are the key points in nursing care of patients with PTCD,which play important roles in alleviating clinical symptoms,improving treatment outcome and pro-moting the patients' quality of life.

Objective To investigate the characteristic and its clinical value of tumor necrosis factor (TNF)-α and its receptor, interleukin (IL)-1β and its receptor in serum and bronchoalveolar lavage fluid(BALF) in patients with pulmonary tuberculosis and to determine the role of them in the immunopathogenesis of tuberculosis. Methods The concentrations of TNF-α,soluble TNF receptor (sTNF-R) Ⅰ, IL-1β and IL-1 receptor were measured using sandwish ABC-enzyme-linked immunosorbent assay (ELISA) method in serum and BALF of 46 patients with active tuberculosis and 21 patients with inactive tuberculosis, and in the serum of 20 cases of healthy control. Meanwhile the above-mentioned cytokine levels in serum and BALF of 19 patients with active tuberculosis were followed up. Differences between groups were assessed for significance by t test. Results The TNF-α,sTNF-R Ⅰ, IL-1β and IL-1 receptor levels and TNF-α/sTNF-R Ⅰ ratios in BALF of active tuberculosis group were (286.2±96.3) pg/L,(2 431.5±1 124.6) pg/L,(58.6±3.2) pg/L,(162.4±17.1) pg/L and 0.06±0.01, respectively, which were all significantly higher than those with inactive tuberculosis group (t=3.36,3.25,2.95,2.27 and 3.12 respectively; P<0.05). The TNF-α,sTNF-R Ⅰ,IL-1β and IL-1 receptor levels and TNF-α/sTNF-R Ⅰ ratios in BALF of cavernous tuberculosis group were (381.4±106.4) pg/L,(2 824.7±1 318.5) pg/L,(66.4±4.6) pg/L,(176.4±18.7) pg/L and 0.07±0.01, respectively,which were all significantly higher than those of non-cavernous tuberculosis group (t= 3.46,2.37, 3.19, 2.99 and 3.22, respectively; P<0.05). After 2-month' antituberculosis treatments, among 19 cases, the TNF-α,sTNF-R Ⅰ,IL-1β and IL-1 receptor levels and TNF-α/sTNF-R Ⅰ ratios in BALF of 16 cases were significantly lower than those at the beginning of treatments (t= 3.26,3.17, 3.28, 2.92 and 3.12 respectively; P<0.01). Meanwhile, their clinical symptoms improved, sputum smear negative, lesions on chest X-ray resolved and the cavity shrinked or closed. Conclusions TNF-α, sTNF-R Ⅰ, IL-1β and IL-1 receptor are likely to be involved in the immunopathogenesis of tuberculosis. Detection of TNF-α, sTNF-R Ⅰ, IL-1β and IL-1 receptor levels in the serum and BALF is helpful to understand the activity of disease, determine the clinical pattern of disease,assess the prognosis of disease and monitor the therapeutic effect in patients with pulmonary tuberculosis.

Testicular coefficient of the middle dose group (0.72% ± 0.10 %vs. 0.64% ± 0.08%) was significantly increased (P<0.05); the content of SOD in testicular of the middle dose group, the high dose groups and theNanbao capsules group (152.71 ± 38.10 U/mg, 122.32 ± 52.76 U/mg, 94.38 ± 22.20 U/mgvs. 25.30 ± 14.21 U/mg) increased (P<0.01); the content of SOD in liver of the middle dose group and theNanbaocapsules group (77.71 ± 26.35 U/mg, 74.10 ± 26.04 U/mgvs. 57.92 ± 17.17 U/mg) significantly increased (P<0.05).Conclusion Rhodiola extract can improve the ability of sexual behavior of male mice, and improve the antioxidant capacity of testis and liver.

OBJECTIVE: To explore the current situation and correlation between the attitude toward seeking professional psychological help and perceived stress in policemen. METHODS: The Attitude Toward Seeking Professional Psychological Help Scale and the Perceived Stress Scale were used to conduct surveys in 240 policemen, who were selected from Sichuan practice training bases by cluster random sampling method.RESULTS: The total scores of the attitude toward seeking professional psychological help and perceived stress in policemen were(94.9±11.9) and(38.6±6.7) respectively. The total score of the attitude toward seeking professional psychological help of rural policemen was higher than that of urban policemen(P<0.05). The total scores of the attitude toward seeking professional psychological help of criminal policemen, security policemen and prison guards were higher than that of logistics policemen(P<0.05). The total score of perceived stress of policemen aged over 40 was higher than those of policemen aged in the 20 s and 30 s(P<0.05). The total score of perceived stress of divorced policemen was higher than those of married and unmarried policemen(P<0.05). The total score of the attitude toward seeking professional psychological help was negatively correlated with the total score of perceived stress(P<0.01). The total score of the attitude toward seeking professional psychological help of policemen in the high risk pressure group was lower than that in the normal pressure group(P<0.05). CONCLUSION: The attitude toward seeking professional psychological help of policemen was at the average level and was negatively correlated with their psychological stress.

Objective:To analyze the effects of enhanced recovery after surgery(ERAS) concept on anesthetic agents in our hos-pital in order to provide evidence for rational drug use. Methods:The patients received ERAS care and surgery from departments of o-torhinolaryngology,gynecology and urology during June and December in 2016 were selected into ERAS group. Meanwhile, the pa-tients received usual care and routine operation were selected into the traditional group. Anesthetic agents of the two groups were then analyzed. Results:The anesthetic agents costs, the usage rate and expenses of patient controlled analgesia pump and the total drug costs of ERAS groups were significantly lower than those of the traditional groups(P<0.05 or P<0.01). Conclusion:With the de-velopment of ERAS concept, the patients can receive good diagnosis and treatment. Meanwhile, anesthetic agents costs, total drug costs and drug proportion decrease as well.

OBJECTIVETo investigate the effect of amphotericinB (AmB) on migration and invasion of esophageal carcinoma Eca109 cells exposed to hypoxia and explore the molecular mechanisms.

METHODSRoutinely cultured esophageal carcinoma Eca109 cells were treated with 0, 1.25, 2.5, or 5 µg/ml AmB in hypoxic condition (3% O2, 5% CO2, and 92% N2) for 24 h. The cell migration and invasion were assessed by cell scratch test and Transwell chamber assay, respectively. Real-time quantitative PCR and Western blotting were used to detect the mRNA and protein expressions of hypoxia-inducible factor-1α (HIF-1α), matrix metalloproteinase-2 (MMP-2), and E-cadherin in the cells, respectively.

RESULTSCompared with the control cells, the cells treated with different doses of AmB showed attenuated ability of migration and invasion (P<0.05). AmB treatment resulted in significantly lowered mRNA and protein expressions of MMP-2 (P<0.05) and increased expressions of E-cadherin (P<0.05); the protein expression of HIF-1α decreased significantly in cells after AmB treatment (P<0.05) but its mRNA levels showed no significant changes (P>0.05).

CONCLUSIONAmB can suppress the migration and invasion of esophageal carcinoma Eca109 cells in hypoxic microenvironment possibly by regulating the expressions of HIF-1α, MMP-2 and E-cadherin.

Objective:To investigate the effects of ginkgolide B on neurological function recovery and the Wnt/β-catenin pathway after ischemic stroke in mice.Methods:Fifty-five C57/BL6 mice were selected, of which 10 mice were kept as the sham group and the remaining 45 mice were constructed as the ischemic stroke model. There were 40 mice who finally completed the modeling, and then they were randomly divided into the blank control group (GB0w), short-course administration group (GB1w), long-term administration group (GB2w), and long-term administration+antagonist group (GB2w+PRI-724), with 10 mice in each group. There was no drug intervention after MCAO in GB0w. The mice in GB1w were given ginkgolide B (10 mg/kg) 0.1 ml within 1 week after MCAO; in GB2w were given ginkgolide B (10 mg/kg) 0.1 ml within 2 weeks after MCAO; and in GB2w+PRI-724 were nasally fed ginkgolide B (10 mg/kg) 0.1 ml within 2 weeks after MCAO; and selective antagonist PRI-724 was given 3 h before administration of ginkgolide B on days 8 to 14. Neurological function scores, walking on rotor bar test scores, expression of transforming growth factor-β1 (TGF-β1), fibroblast growth factor 4 (FGF4), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), Wnt, β-catenin, and glycogen synthase kinase-3β (GSK-3β) were compared among the groups.Results:Compared with the sham group, the expressions of MDA, TNF-α, IL-6, FGF4, and GSK-3β in GB0w, GB1w, GB2w, and GB2w+ PRI-724 were increased, and the expressions of GSH-Px, SOD, TGF-β1, β-catenin, and Wnt were decreased (all P < 0.001). Compared with GB0w, the expressions of SOD, GSH-Px, TGF-β1, Wnt, and β-catenin were increased in GB1w, GB2w, and GB2w+PRI-724, and the expressions of MDA, TNF-α, IL-6, FGF4, and GSK-3β were decreased (all P < 0.001). Compared with GB1w, the expressions of GSH-Px, SOD, TGF-β 1, Wnt, and β-catenin were increased in GB2w and GB2w+PRI-724, and the expressions of IL-6, TNF-α, MDA, FGF4, and GSK-3β were decreased (all P < 0.001). Compared with GB2w, the neural function score, walking on the stick test score, and expressions of IL-6, TNF-α, FGF4, MDA, and GSK-3β were increased in GB2w+PRI-724, while the expressions of GSH-Px, TGF-β1, SOD, Wnt, and β-catenin were decreased (all P < 0.001). Conclusions:Ginkgolide B can effectively improve the neurological function of ischemic stroke mice and may be related to the Wnt/β-catenin pathway.

Background The high-pressure and high-risk nature of the police profession may consume individual resources and lead to job burnout. Objective To understand the current situation of police job burnout, and test potential mediating role of psychological empowerment between social support and job burnout. Methods From May to October 2020, a questionnaire survey was conducted among police officers in cities A and B of Sichuan Province by convenience sampling. The Perceived Social Support Scale, Psychological Empowerment Scale, and Maslach Burnout Inventory-General Survey were used to evaluate social support, psychological empowerment, and job burnout respectively. Mediation effect of psychological empowerment on the relationship between social support and job burnout was tested using bias-corrected bootstrap method. Results Of the 483 questionnaires recovered, there were 461 valid questionnaires (95.44%). The M (P₂₅, P₇₅) scores of social support, psychological empowerment, and job burnout were 5.00 (3.50, 5.83), 3.25 (2.00, 4.25), and 3.61 (2.43, 3.88), respectively. The positive rate of job burnout was 93.92% (433/461), of which 42.51% (196/461) and 51.41% (237/461) of the participants were at mild to moderate and severe levels of job burnout respectively. The results of Spearman correlation analysis showed that social support and psychological empowerment were negatively correlated with job burnout (r=−0.265, −0.328, P<0.01), and social support was positively corrected with psychological empowerment (r=0.390, P<0.01). The Bootstrap test results showed that social support negatively affected job burnout (β=−0.193, P<0.001) and positively affected psychological empowerment (β=0.330, P<0.001). Psychological empowerment negatively affected job burnout (β=−0.212, P<0.001) and played a partial mediating role in the relationship between social support and job burnout, and the effect value was −0.070 (95%CI: −0.097, −0.047) that accounted for 36.27% of the total effect. Conclusion Job burnout is prevalent among the police officers. Social support has a negative effect on job burnout, and psychological empowerment plays a partial mediating role between social support and job burnout.
