Objective To investigate the effects of ulinastatin on the myocardial injury in patients undergoing live donor liver transplantation.Methods Forty patients (AHA classification grade A or B),aged 40-64 yr,with a body mass index of 18-25 kg/m2,scheduled for live donor liver transplantation,were randomly divided into 2 groups ( n =20 each):control group (group C) and ulinastatin group (group U).Anesthesia was induced with midazolam,sufentanil,and cisatracurium besilate.The patients were tracheal intubated and mechanically ventilated.Ulinastatin 300 000 IU in 100 ml of normal saline was infused intravenously over 30 min after anesthesia induction and then the infusion was repeated at 4 h interval until the end of operation in group U,while the equal volume of normal saline was given in group C.Blood samples were taken from the central vein immediately before skin incision (T0,baseline),at 30 min of anhepatic phase (T1),at 30 min of neohepatic phase (T2),and at 0,4 and 24 h after operation (T3-5) for determination of the concentrations of serum cardiac troponin Ⅰ (cTnI),creatine kinase-MB (CK-MB) and N-terminal pro-brain natriuretic peptide (NT-proBNP).The changing rates of cTnI and CK-MB at T1-5 were calculated.The use of cardiovascular drugs and cardiovsscular accidents were recorded during operation.Results The serum cTnI,CK-MB and NT-proBNP concentrations were significantly higher at T2-5 than at T0 in the two groups ( P ＜ 0.05).Compared with group C,the serum cTnI,CK- MB and NT-proBNP concentrations at T2-5 were significantly deceased in group U ( P ＜ 0.05).The maximal changing rates of cTnI,CK-MB and NT-proBNP concentrations were 4.71 ± 1.62,6.85 ± 1.53 and 4.96 ± 1.23 respectively in group C,decreased to 3.26 ± 1.51,4.56 ± 1.62 and 3.67 ± 1.02 respectively in group U.There was no significant difference in the incidence of cardiovascular accidents and the use of dopamine between the two groups.Conclusion Intravenous infusion of ulinastatin can attenuate the myocardial injury to some extent in patients undergoing live donor liver transplantation.

Objective To investigate healthcare-associated infection(HAI)in patients in a cancer hospital,provide reference for controlling HAI in cancer patients,and guide rational use of antimicrobial agents.Methods Clinical data of patients in a cancer hospital between August 2006 and July 2012 were analyzed retrospectively.Results The incidence of HAI case was 1 .53% (2 060/134 389),and annual incidence showed a downward trend.The main in-fection site was lower respiratory tract (46.46%,n=957),followed by bloodstream (15.63%,n=322),abdominal and pelvic (14.03%,n=289).The main pathogens were Pseudomonas aeruginosa (16.16%,n=350),Staphylo-coccus aureus (9.97%,n=216),Klebsiella pneumoniae (9.79%,n=212),Escherichia coli (9.65%,n=209), and Candida albicans (6.51 %,n=141 ).Gram-negative bacilli,including Klebsiella pneumoniae and Escherichia coli ,were sensitive to carbapenems and β-lactamase inhibitors.Conclusion Lower respiratory tract is the major HAI site in patients with cancer,and gram-negative bacteria are the main pathogens.Carbapenems andβ-lactamase inhibitors are recommended for the empirical treatment of HAI in cancer patients.

Purpose To investigate the role of SOCS3 on diabetic renal injury. Methods Male CD-1 mice were randomly divided into four groups:control group, diabetic group, empty plasmid vector transfection group and SOCS3 plasmid transfection group. The diabet-ic mice were induced by intraperitoneal injection of STZ at a dose of 150 mg/kg body weight. The mice of transfection group were re-ceived an injection of SOCS3 plasmid or empty vector at every 7 days thereafter. Specimens were collected at 12 week after STZ injec-tion. The morphological changes of tubular epithelial cells were observed by transmission electron microscope. RT-PCR and immuno-histochemistry were used to determine the mRNA and protein expression of CK18 and α-SMA. Western blotting analysis was used to determine the protein expression of SOCS3, p-STAT3, CK18 and α-SMA. Results SOCS3 overexpression in kidney down-regulated the levels of p-STAT3 andα-SMA but up-regulated the expression of CK18. Conclusion Overexpression of SOCS3 can ameliorate the tubular epithelial-mesenchymal transdifferentiation of diabetic mice via inhibiting the phosphorylation of STAT3.

Purpose To investigate the role of S3I-201 on tubular interstitial lesion in lupus nephritis.Methods MRt/MpJ mice were designated as the control group.MRL/lpr nice were randomly divided into LN group,S3I-201 group and DMSO group.The serum and 24 h-urine were collected to detect the serum creatinine,blood urea nitrogen and urine protein.Immunohistochemistry was used to detect the expression of FN.Western blotting analysis was used to determine the expression of E-cadherin,α-SMA,MCP-1,ICAM1,STAT3 and p-STAT3.Results Compared with the expression level in control group,the protein level of α-SMA,MCP-1,ICAM1 and FN were increased in renal tissue of MRL/lpr mice,while the expression of E-cadherin was markedly decreased.And the STAT3 was activated in renal tissue of MRL/lpr mice.The administration of S3I-201 could inhibite the activation of STAT3 and ameliorate the expression of E-cadherin,α-SMA,MCP-1,ICAM-1 and FN.Conclusion S3I-201 can relieve the tubular interstitial leison,which maybe concerned with the phosphorylation of STAT3.

Objective To explore the effect of self-management efficacy on compliance of taking capecitabine in discharged patients with colorectal cancer. Methods A total of 82 patients with colorectal cancer who were treated in the First Affiliated Hospital with Nanjing Medical University from January 2014 to December 2016 were selected by convenient sampling method. The general data, drug compliance and self-management efficacy of patients were investigated and the relationship between drug compliance and self-management efficacy was analyzed. Results Compliance score of taking capecitabine for 82 patients with colorectal cancer was (6.42±1.65) points; among them 5 cases were excellent (6.10%), good in 54 cases (65.85%) and poor in 23 cases (28.05%). Compliance of taking capecitabine in discharged patients with colorectal cancer was positively correlated with the scores of all dimensions and total score of self-management efficacy. Self-management efficacy was an independent factor affecting the compliance of patients with capecitabine, which could explain 13.4% of the overall variation of compliance. Conclusions Compliance of taking capecitabine in discharged patients with colorectal cancer is unsatisfied. Education on self-management efficacy from medical staff could improve the patients' medication adherence and their quality of life.

Objective To explore the protective effect of aucubin on the photoageing of the skin that induced by ultraviolet (UVB) radiation. Methods Human skin fibroblasts were divided into normal group, model group and high, medium and low dose groups of apocynin by random method. Except the normal group, the other groups of cells were subjected to UVB radiation with a radiation wavelength of 311 nm, irradiation intensity of 9.00 mw/cm2, radiation time of 2.8 s, radiation dose of 25 mJ/cm2. The cells in the high, medium and low doses of aglycone were cultured for 24 h at an equal volume of 400, 200, 100 μg/ml, and then subjected to UVB irradiation, and then cultured for 24 h. The normal group and the model group were cultured for 48 h in a common medium. The apoptosis rate of each group was detected by flow cytometry. The levels of IL-1, IL-6 and TNF-α in each group were detected by ELISA. The expressions of Bax and Bcl-2 mRNA in each group were detected by RT-PCR. Results Compared with the model group, the apoptosis rate (4.84% ± 0.24%, 12.32% ± 0.67% vs. 35.63% ± 2.77%) in the medium and high dose group significantly decreased (P<0.05), the content of IL-1 (21.14 ± 1.94 ng/ml, 16.17 ± 0.74 ng/ml vs. 22.55 ± 1.02 ng/ml), IL-6 (17.46 ± 0.93 ng/ml, 14.51 ± 0.79 ng/ml vs. 18.39 ± 2.05 ng/ml), TNF-α (44.21 ± 1.16 ng/ml, 35.94 ± 3.08 ng/ml vs. 45.67 ± 2.28 ng/ml) significantly increased (P<0.05). Compared with the model group, the expression of Bax mRNA (0.29 ± 0.05, 0.42 ± 0.05, 0.51 ± 0.04 vs. 0.59 ± 0.05) significantly decreased, and the expression of Bcl-2 mRNA (0.52 ± 0.04, 0.44 ± 0.03, 0.35 ± 0.03 vs. 0.26 ± 0.04) significantly increased (P<0.05). Conclusions The aucubin has protective function to the damage of skin fibroblasts which is induced by UVB radiation, indicating the protective function of decreasing Bax mRNA expression, increasing Bcl-2 mRNA expression, reducing the expression of inflammatory factor IL-1, IL-6, TNF-α, holding-up the cell apoptosis which is induced by UVB radiation, and inhibiting apoptosis of cell that caused by UVB radiation, playing an role of protective fibroblasts for delay of the photoageing.

Objective:To investigate the clinical diagnostic value of MRI retention enema cannula enhanced scanning in the high complex anal fistula.Methods:The clinical data of 60 anal fistula patients underwent surgery treatment from May 2020 to May 2022 in Affiliated Hospital of Shanxi University of Traditional Chinese Medicine were retrospectively analyzed. All patients underwent MRI plain scanning and enhanced scanning before operation. Compared with the surgical results, the difference between MRI plain scanning and enhanced scanning in the diagnosis of high complex anal fistula was compared.Results:All of the 60 patients successfully completed surgical treatment, and 58 cases internal orifices, 55 cases complex anal fistulas and 53 cases high anal fistulas were found intraoperatively. MRI plain scanning results showed 32 cases internal orifices, 46 cases complex anal fistulas and 42 cases high anal fistulas were found. MRI enhanced scanning results showed 54 cases internal orifices, 53 cases complex anal fistulas and 50 cases high anal fistulas were found. Based on surgical results, the coincidence rates of internal orifice, complex anal fistula and high anal fistula in MRI enhanced scanning were significantly higher than those in MRI plain scanning: 93.10% (54/58) vs. 55.17% (32/58), 96.36% (53/55) vs. 83.64% (46/55) and 94.34% (50/53) vs. 79.25% (42/53), and there were statistical differences ( χ2 = 21.76, 4.95 and 5.27; P<0.01 or <0.05). Conclusions:The MRI retention enema cannula enhanced scanning has obvious advantages in the diagnosis of high complex anal fistula, which provides scientific reference value for the diagnosis and operation of high complex anal fistula in clinic.

Objective: To evaluate the value of multi-detector CT (MDCT) upper airway imaging in the diagnosis of obstructive sleep apnea hypopnea syndrome ( OSAHS) and in determining the location of upper airway obstruction． Methods : MDCT was used to scan the upper airways of 85 clinically confirmed adult patients with different degrees of OSAHS (73 males and 12 females) in calm breathing phase and forced inhalation phase and 60 normal adults (50 males and 10 females) in calm breathing phase to obtain nasal cavity，nasopharynx，palatopharynx and oglosopharynx volumes．Parapharyngeal fat volume was measured in OSAHS patients and normal subjects．In addition，three groups of clinical data related to OSAHS patients were recorded，including sleep apnea hypopnea index (AHI) ，body mass index ( BMI) and lowest blood oxygen saturation ( LaSO2 ) ．Finally，the measured data and clinical data of each group were statistically analyzed. Results : The volume of nasopharynx and palatopharynx in the calm breathing group was significantly smaller than that in the control group，with statistical significance．Palatopharyngeal volume forced inspiratory phase was significantly smaller than calm breathing phase in the experimental group．The parapharyngeal fat volume in the experimental group was significantly higher than that in the control group．AHI was positively correlated with BMI and parapharyngeal fat volume．LaSO2 was negatively correlated with AHI and BMI，respectively． Conclusion MDCT upper airway imaging has good clinical application value in the diagnosis，treatment and postoperative evaluation of OSAHS disease due to the significant anatomical difference between OSAHS patients and normal subjects.
