Objective To investigate the clinical effect of fissure for ligamentum teres hepatic (LTH) approach in hepatectomy.Methods The method of cross-sectional study was adopted.The clinical data of the 85 patients undergoing hepatectomy through fissure for LTH approach who were admitted to the West China Hospital of Sichuan University from February 2009 to December 2013 were collected.Among all the 85 cases, there were 61 of hepatocellular carcinoma, 12 of intrahepatic bile duct stones, 6 of bile duct cellular carcinoma and 6 of metastatic hepatic carcinoma.The operations involved dissecting fissure for LTH, dealing with portal vein, hepatic artery and bile duct inside the fissure, lowering the hepatic portal, mutilating hepatic parenchyma, and undergoing the hepatic left lateral lobectomy, left hemihepatectomy, mesohepatectomy, hepatic left and/or right trisegmentectomy.Operation method, operation time, volume of intraoperative blood loss, intraoperative blood transfusion, postoperative drainage-tube removal time and complications were recorded.The follow-up including recurrence and metastasis of tumor and survival of patients was conducted by outpatient examination and telephone interview up to August 2015.Measurement data with normal distribution were presented as (x) ± s.Measurement data with skewed distribution were presented as M (range).The survival rate was caculated by Kaplan-Meier method.Results The 85 cases of hepatectomy were successfully completed through fissure for LTH approach, including 19 cases of hepatic left lateral lobectomy (9 with hepatocellular carcinoma, 6 with intrahepatic bile duct stones, 1 with bile duct cellular carcinoma, 3 with metastatic hepatic carcinoma), 20 cases of left hemihepatectomy (8 with hepatocellular carcinoma, 5 with intrahepatic bile duet stones, 4 with bile duct cellular carcinoma, 3 with metastatic hepatic carcinoma), 5 cases of left hemihepatectomy + caudate lobectomy (3 with hepatocellular carcinoma, 1 with intrahepatic bile duct stones, 1 with bile duct cellular carcinoma), 14 cases of meso-hepatectomy (14 with hepatocellular carcinoma) and 27 cases of hepatic left and/or right trisegmentectomy due to hepatocellular carcinoma (15 of hepatic left trisegmentectomy and 12 of hepatic right trisegmentectomy).No perioperative death occurred.The median operation time was 280 minutes (range, 95-430 minutes).The median volume of intraoperative blood loss was 450 mL (range, 200-3 200 mL).There were 18 cases of intraoperative blood infusion.The postoperative peritoneal drainage-tube removal time was 3 days (range, 2-5 days).Eleven patients with postoperative complications recovered after symptomatic conservative treatment, including 6 with lung infection, 4 with peritoneal effusion and 1 with abdominal infection.There was no case of intra-abdominal bleeding, bile leakage or hepatic failure.No patient died within 1 month after operation.Seventy-nine patients were followed up for a median time of 38 months (range, 18-53 months) with a follow-up rate of 92.9％ (79/85).The 1-year overall survival rate and l-year disease-free survival rate were 79.0％ and 65.0％, and the 3-year overall survival rate and 3-year disease-free survival rate were 56.0％ and 34.0％, respectively.Conclusion Hepatectomy through fissure for LTH approach is safe, effective and easily operable, with a good short-term outcome.

Objective To estimate the effect of itermittent subglottic secretions drainage(ISSD)on management of artificial airway to prevent tube-related pulmonary pneumonia.Methods One hundred ICU patients with intubation for artificial airway were divided equally into control and experiment group by random digits table.Both were managed with construction of artificial airway and besides the experiment group received ISSD. The two groups were compared in terms of incidence and occurrence time of catheter-related pneumonia, time for airway opening and ICU stay.Result The incidence and the occurrence time of pneumonia, time for airway opening and ICU stay time in the experiment group were significantly lower or shorter than those in the control group with statistical difference(all P<0.05).Conclusion ISSD is effective in decreasing the incidence of catheter related pneumonia, shortening the occurrence time of catheter related pneumonia and ICU stay time for the patients with artificial airway.

Purpose To observe the action time of parthenolide (PTN) as selective nuclear factor-κB(NF-κB) inhibitor in heart of rats.Methods Forty SD rats were randomly divided into control(CON) group,PTN group,dimethyl sulfoxide(DMSO) group,lipopolysaccharide(LPS) group and PTN+LPS group.The first day:PTN group,DMSO group and PTN+LPS group rats were respectively injected interapertoneally PTN(500 μg/kg) and DMSO; other groups rats were injected interapertoneally equivalent saline.The second day(in equivalent to 24 h after injecting PTN):in LPS group and PTN+LPS group LPS(12.5 mg/kg) was administered subcutaneously; other group rats were injected subcutaneously equivalent saline.Every heart was obtained in equivalentce to 1 h after injecting LPS to measure the expression of NF-κB p50 in nucleus,inhibitory kappaB(IκBα) and phosphorylation inhibitory kappaB(p-IκBα) in cytoplasm of cardiac myocytes through Western blotting.Results Compared with CON group,the expression of NF-κB p50,IκBα and p-IκBα had no difference in PTN and DMSO group.And in LPS group and PTN + LPS group,the expression of NF-κB p50 up-regulated significantly(P＜0.05),IκBα down-regulated(P＜0.05) and p-IκBα up-regulated significantly(P＜0.05).Conclusion LPS can activate NF-κB in 1 h and PTN in rats after 24 h has few effect.

Objective To observe the effect of topical application with warm and wet carthamus tinctorius alcohol and anisodaminum on phlebitis caused by mannitol injection. Methods 100 patients with fractured bones suffered from phlebitis caused by mannitol injection were randomized into the observation group and the control group with 50 cases in each group. The observation group adopted topical application with warm and wet carthamus tinctorius alcohol and anisodaminum while the control received external application of 50% magnesium sulfate. The dosage was 3 hours per time,2 times a day, one time in the morning and afternoon respectively. The treatment continued till the phlebitis disappeared and the effect at the 24th,48th and 72th post treatment was compared between the two groups. Results The effect at the above mentioned time points in the obsevation group was superior to that of the control group(P＜0.05).Conclusion Topical application with warm and wet carthamus tinctorius alcohol and anisodaminum on phlebitis caused by mannitol injection proved to be safe and had no adverse effect.

Aim To observe the expression of epider-mal growth factor receptor ( EGFR) in cerebral tissues around hematomas after intracerebral hemorrhage, and explore the effects of EGFR on activation of astrocytes derived from rats and the involved mechanisms. Meth-ods The specimens of cerebral tissues around hemo-tomas after intracerebral hemorrhage undergoing hemo-tomas removal operation were collected and then divid-ed into 4 groups according to the time of intracerebral hemorrhage: <1 d, 1 ~5 d, 6 ~10 d and >10 d groups. Each group included 20 cases. At the same time, 20 dropped brain tissues distant to hemorrhage in the operative process were collected as control group. Immunohistostaining and Western blot were used to measure the expression of EGFR. After isolation and culturing, the astrocytes of rat cortex were treated with culture solution ( control group) , CNTF that was used to activate astrocytes, scramble siRNA + CNTF and EGFR siRNA +CNTF for 24h, respectively. The ex-pression of glial fibrillary acidic protein ( GFAP) mR-NA was detected through fluorescence real-time quanti-tative PCR. In addition, the protein levels of GFAP, signal transducers and activators of transcription 3 ( STAT3 ) and phosphorylated STAT3 ( p-STAT3 ) were examined using Western blot. Results With the ex-tension of intracerebral hemorrhage time, positive sig-nal index and protein expression levels of EGFR gradu-ally elevated, reached the peak on 6 ~10d, and then decreased after 10 d. There was statistical difference ( P<0. 01 ) . The expression levels of GFAP mRNA and protein as well as p-STAT3 were significantly in-creased in cells treated with CNTF alone as compared to control group ( P <0. 01 ) , whereas these effects were almost completely reversed by EGFR siRNA transfection ( P <0. 01 ) . Additionally, there was no statistical difference in STAT3 protein levels among groups ( P >0. 05 ) . Conclusions EGFR expression is upregulated in the cerebral tissues around hemotomas after intracerebral hemorrhage. Gene silence of EGFR contributes to suppressing the activation of astrocytes derived from rats, which may be involved in the block-ade of STAT3 phosphorylation.
