ObjectiveTo observe the effect of Gankang Ⅱ in reducing bilirubin level of patients with chronic hepatitis B,and discuss the mechanism.Methods124 cases hyperbilirubinemia patients with chronic hepatitis B were randomly divided into Gankang Ⅱ treatment group (the treatment group for short),and Yinzhihuang particles treatment group (the control group for short),with 62 eases in each group.The cure rate,recover rate of the treatment group and control group were observed,together with the changes of ALT,AST,GGT,and TBiL.Results①The cure rate was 80.6％,the recover rate was 19.4％ in the treatment group; the cure rate of was 62.9％ and the recover rate was 37.1％ in the control group; the cure rate of the treatment group was obviously higher than the control group.② There was no significant difference between the treatment group and the control group on TBiL,ALT,AST,and GGT before the treatment (P＞0.05).while after treated,TBiL (20.75±3.77) μmol/L,ALT (52.53± 12.23) U/L,AST (51.75 ±9.93) μmol/L,GGT (48.75 ±16.68) U/L of the treatment group were obviously lower than the TBiL(26.68 ±4.99)μmol/L,ALT(79.68± 1 1.92)U/L,AST (60.12 ± 8.12) μmol/L,GGT (58.97±15.47)U/L of control group.There was significant difference(P＜0.05～0.01).ConclusionThe effect of Gankang Ⅱ in reducing the bilirubin level of patients with chronic hepatitis B was sound.

Objective To analyze the risk factors of nosocomial infection in Department of Neurosurgery and to provide evidence for the prevention and treatment of infection.Methods A total of 931 patients with neurosurgery operation in our hospital from January 2012-January 2016 were collected medical history data immediately after admission,including age,gender,underlying diseases,and primary diseases.Surgical records include preoperative white blood cell count,blood glucose level before operation,duration of operation,and reoperation.Hospitalization records include hospitalization time,without the use of corticosteroids,with or without the use of proton there is no pump inhibitor,and tracheal intubation / incision.Patients were divided into infection group and non infection group according to whether the hospital infection occurred during hospitalization.The difference of two groups of clinical data with statistically significant variables was Logistic multivariate regression analysis.Results There were 112 patients with nosocomial infection,the infection rate was 12.03％,and the infection occurred in the postoperative 3-25 d.The main infection site was postoperative wound,accounting for 35.7％;respiratory tract,accounting for 34.8％.There were 64 strains of pathogenic bacteria,81 strains of Gram-negative bacteria,accounting for 64.1％,21 strains of gram positive bacteria,accounting for 32.8％,2 strains of fungi,accounting for 3.1％.There were significant difference between infection group and non infection group in ≥ 60 years,with basic diseases,reoperation,combined with other injuries,white blood cells,abnormal preoperative hyperglycemia,glucocorticoid use,proton pump inhibitors use,tracheotomy,hospitalization time,operation time (P ＜ 0.05).Further Logisitc regression analysis showed that age,reoperation,hospitalization time,preoperative high blood sugar and tracheotomy were the risk factors of nosocomial infection in Department of neurosurgery.Conclusions For the older,reoperation,longer hospitalization time,preoperative hyperglycemia and tracheotomy patients can take specific measures to improve the immunity of the patients,the rational use of antimicrobial drugs to avoid the occurrence of postoperative infection.

Objective: To investigate the effects of emodin on lipopolysaccharide (LPS)-induced inflammation and damage in HK-2 cells. Methods: The HK-2 cells were divided into blank group, emodin group, LPS group, and LPS+emodin group. The emodin group was treated with culture medium containing 0.5 μg/ml emodin, the LPS group was treated with culture medium containing 10 μg/ml LPS, the LPS+emodin group was treated with culture medium containing both 0.5 μg/ml emodin and 10 μg/ml LPS, and the blank group was cultured with fresh medium. Twelve hours later, HK-2 cells from each group were harvested for the analysis. The mRNA levels of oligonucleotide receptor protein 3 (NLRP3), IL-1β, IL-18, TNF-α, and neutrophil gelatinase-associated lipocalin (NGAL) in each group were determined by RT-PCR. Results: Compared to the blank group, the mRNA levels of NLRP3 (2.74 ± 0.38 vs. 1.00 ± 0.14), IL-1β (2.40 ± 0.33 vs. 1.00 ± 0.19), and IL-18 (3.00 ± 0.42 vs. 1.00 ± 0.07), NGAL (31.73 ± 3.41 vs. 1.00 ± 0.07), and TNF-α (9.73±1.60 vs. 1.00 ± 0.11) significantly increased by LPS stimulation (P<0.05). Compared to the LPS group, the mRNA expression of NLRP3 (1.98 ± 0.24 vs. 2.74 ± 0.39), IL-1β (1.54 ± 0.24 vs. 2.40 ± 0.33), and IL-18 (2.09 ± 0.53 vs. 3.00 ± 0.42), NGAL (16.76 ± 1.72 vs. 31.73 ± 3.41) and TNF-α (9.73 ± 1.60 vs. 4.65 ± 1.09) in HK-2 cells of LPS+emodin group significantly decreased (P<0.05). Conclusions The emodin protects HK-2 cells from LPS-induced damage and inflammation by inhibiting NLRP3 inflammasome activation.
