Objective: To explore the influence of directed restrictive fluid management strategy (RFMS) on patients with serious burns complicated by severe inhalation injury. Methods: Sixteen patients with serious burns complicated by severe inhalation injury hospitalized in our department from December 2014 to December 2017, meeting the inclusion criteria and treated with RFMS, were enrolled in directed treatment group. Thirty-four patients with serious burns complicated by severe inhalation injury hospitalized in our department from December 2012 to December 2017, meeting the inclusion criteria and without RFMS, were enrolled in routine treatment group. Medical records of patients in 2 groups were retrospectively analyzed. Within post injury day 2, mean arterial pressure (MAP), central venous pressure (CVP), extravascular lung water index (ELWI), global end-diastolic volume index, and pulmonary vascular permeability index of patients in directed treatment group were monitored by pulse contour cardiac output monitoring technology, while MAP and CVP of patients in routine treatment group were monitored by routine method. On post injury day 3 to 7, patients in 2 groups were treated with routine fluid supplement therapy of our Department to maintain hemodynamic stability, and patients in directed treatment group were treated according to RFMS directed with goal of ELWI≤7 mL·kg^-1·m^-2. On post injury day 3 to 7, total fluid intake, total fluid output, and total fluid difference between fluid intake and output within 24 h, value of blood lactic acid, and oxygenation index of patients in 2 groups were recorded. Occurrence of acute respiratory distress syndrome (ARDS) on post injury day 3 to 7 and 8 to 28, mechanical ventilation time within post injury day 28, and occurrence of death of patients in 2 groups were counted. Data were processed with chi-square test, t test, and analysis of variance for repeated measurement. Results: The total fluid intakes within 24 h of patients in directed treatment group were close to those in routine treatment group on post injury day 3, 4, 5, 6, 7 (t=-0.835, -1.618, -2.463, -1.244, -2.552, P>0.05). The total fluid outputs and total fluid differences between fluid intake and output within 24 h of patients in 2 groups on post injury day 3 were close (t=0.931, -2.274, P>0.05). The total fluid outputs within 24 h of patients in directed treatment group were significantly higher than those in routine treatment group on post injury day 4, 5, 6, 7 (t=2.645, 2.352, 1.847, 1.152, P<0.05). The total fluid differences between fluid intake and output within 24 h of patients in directed treatment group were (2 928±768), (2 028±1 001), (2 186±815), and (2 071±963) mL, significantly lower than (4 455±960), (3 434±819), (3 233±1 022), and (3 453±829) mL in routine treatment group (t=-4.331, -3.882, -3.211, -4.024, P<0.05). The values of blood lactic acid of patients in directed treatment group and routine treatment group on post injury day 3, 4, 5, 6, 7 were close (t=0.847, 1.221, 0.994, 1.873, 1.948, P>0.05). The oxygenation indexes of patients in directed treatment group on post injury day 3 and 4 were (298±78) and (324±85) mmHg (1 mmHg=0.133 kPa ), which were close to (270±110) and (291±90) mmHg in routine treatment group (t=-1.574, 2.011, P>0.05). The oxygenation indexes of patients in directed treatment group on post injury day 5, 6, 7 were (372±88), (369±65), and (377±39) mmHg, significantly higher than (302±103), (313±89), and (336±78) mmHg in routine treatment group (t=3.657, 3.223, 2.441, P<0.05). On post injury day 3, 4, 5, 6, 7, patients with ARDS in directed treatment group were less than those in routine treatment group, but with no significantly statistical difference between the 2 groups (χ²=0.105, P>0.05). On post injury day 8 to 28, patients with ARDS in directed treatment group were significantly less than those in routine treatment group (χ²=0.827, P<0.05). The mechanical ventilation time within post injury day 28 of patients in directed treatment group was apparently shorter than that in routine treatment group (t=-2.895, P<0.05). Death of patients in directed treatment group within post injury day 28 was less than that in routine treatment group, but with no significantly statistical difference between the 2 groups (χ²=0.002, P>0.05). Conclusions Under the circumstance of hemodynamics stability, RFMS directed with goal of ELWI≤7 mL·kg^-1·m^-2 on post injury day 3 to 7 is an useful strategy, which can reduce occurrence rate of ADRS and shorten mechanical ventilation time of patients with serious burns complicated by severe inhalation injury at late stage of burns.

Objective To evaluate the relationship between the change rate of regional cerebral ox-ygen saturation ( rSO2 ) and early postoperative cognitive function during laparoscopic surgery in elderly pa-tients. Methods Fifty American Society of Anesthesiologists physical status Ⅰ-Ⅱ patients, aged 65-80 yr, scheduled for elective laparoscopic radical resection for colorectal cancer under general anesthesia, were enrolled in this study. rSO2 was recorded at 5 min before anesthesia induction ( T0 ) , 5 min after tra-cheal intubation ( T1 ) , 5 min after changing position ( T2 ) , 1 h after changing position ( T3 ) , 5 min after stopping pneumoperitoneum ( T4 ) , and 5 min after changing to supine position at the end of pneumoperito-neum ( T5 ) . The change rate of rSO2 was calculated at T3 . Mini-Mental State Examination scores were per-formed at 1 day before surgery and 3 days after surgery. The patients were divided into cognitive disorder group and non-cognitive disorder group. Results Compared with non-cognitive disorder group, rSO2 was significantly increased at T2-5 , and the change rate of rSO2 was enlarged in cognitive disorder group ( P<0. 05) . The change rate of intraoperative rSO2 was negatively correlated with Mini-Mental State Examination scores at 3 days after surgery (r=-0. 516, P<0. 01). Conclusion The increased change rate of rSO2 during laparoscopic surgery may be related to the development of early postoperative cognitive dysfunction in elderly patients.

BACKGROUNDCisplatin (DDP) is one of most effective and most commonly used therapeutic agent in treating tumors, it can accumulate in the kidney and lead to acute renal failure. MicroRNA-181a can induce cell apoptosis by suppressing the expression of Bcl-2 family. In the present study, we investigated the role of microRNA-181a in the apoptosis of tubular epithelial cell induced by DDP.

METHODSHK-2 cells were cultured, transfected with microRNA-181a inhibitor for 48 hours, and stimulated with 50 µmol/L cisplatin for 24 hours. MicroRNA-181a expression was analyzed by real time PCR, and cell apoptosis was detected by flow cytometry. Moreover, Bcl-2 and Bcl-2-associated X protein (Bax) expression were measured by Western blotting.

RESULTSMicroRNA-181a expression significantly down-regulated in cells transfected with microRNA-181a inhibitor, compared with that in untransfectd cells (21.19 ± 2.01 vs. 38.87 ± 1.97, P < 0.05). Cell apoptosis induced by DDP significantly decreased in cells transfected with MicroRNA-181a inhibitor. Compared with DDP treated cells alone, Bcl-2 expression strikingly was up-regulated and Bax expression was down-regulated in cells transfected with microRNA-181a inhibitor.

CONCLUSIONOne pathway of DDP induces apoptosis of tubular epithelial cell by suppressing Bcl-2 expression is achieved by regulating the target gene of MicroRNA-181a.

OBJECTIVETo study the clinical value of total hemihepatic vascular exclusion (THHVE) in liver resection for patients with hepatocellular carcinoma (HCC) and impaired liver function.

METHODSThe data of 70 patients who underwent liver resection for HCC with impaired liver function between January 2009 and October 2011 were analyzed retrospectively. THHVE was applied in 38 patients (THHVE group), Pringle maneuver in 25 patients (Pringle group) and no vascular occlusion in 7 patients. In the THHVE group, 36 patients were male, 2 were female, average age was (54 ± 9) years. And in Pringle group, 23 patients were male, 2 were female, average age was (53 ± 10) years. Total intraoperative blood loss, blood transfusion rate, clamping time, postoperative complication rate, postoperative hospital stay and postoperative liver function were compared between the THHVE and Pringle group.

RESULTSTotal blood loss ((317 ± 186) ml vs. (506 ± 274) ml, t = -3.025, P = 0.004) and transfusion rate (10.5% vs. 32.0%, χ(2) = 4.509, P = 0.034) were significantly lower in the THHVE group than in the Pringle group. Although the clamping time was longer ((21 ± 5) minutes vs. (17 ± 5) minutes, t = 3.209, P = 0.002), the total bilirubin levels on postoperative day 3 and 7 and ALT levels on postoperative day 1, 3, 7 were significantly lower in the THHVE group than in the Pringle group, and the pre-albumin level on postoperative day 7 was higher in the THHVE group than in the Pringle group. Total complication rate (26.3% vs. 52.0%, χ(2) = 4.291, P = 0.038) and major complication rate (7.9% vs. 28.0%, χ(2) = 4.565, P = 0.033) were lower in the THHVE group than in the Pringle group. And postoperative hospital stay duration was shorter in the THHVE group than in the Pringle group ((14.0 ± 2.6) d vs. (16.4 ± 4.0) d, t = -2.625, P = 0.012).

CONCLUSIONSTHHVE is a safe and effective technique in liver resection for patients with HCC and impaired liver function. It is associated with less blood loss, lower transfusion requirements, better postoperative liver function recovery, lower postoperative complication rate and shorter postoperative hospital stay.

Objective:To explore the effect of long non-coding RNA (lncRNA) C10orf25 on the proliferation and invasion ability of prostate cancer cells and the possible role of miRNA-671-5p (miR-671-5p).Methods:Data from the Gene expression omnibus (GEO) database (data updated in January 2023) were used to analyze the differences in the expression levels of C10orf25 in 137 cases of prostate cancer tissues and paracancerous tissues. Prostate cancer C4-2B, DU-145, 22Rv1, PC-3, LNCaP cell lines and immortalized prostate epithelial RWPE-1 cell lines were selected, and then real-time quantitative fluorescence polymerase chain reaction (qRT-PCR) was used to detect the relative expression levels of C10orf25 in cell lines. The 22Rv1 cells with the lowest relative expression level of C10orf25 were selected and divided into the control group (transfected with negative plasmid) and the C10orf25 group (transfected with C10orf25 plasmid); the CCK-8 method was used to detect the proliferation activity of 22Rv1 cells in both groups at day 1, 2, 3, 4, 5 (expressed as absorbance value); the Transwell method was used to detect the invasion ability of 22Rv1 cells. Linc2GO software was used to predict miR-671-5p with binding sites for C10orf25. Dual luciferase reporter gene assay was used to verify the targeting relationship between C10orf25 and miR-671-5p. qRT-PCR was used to detect the relative expression levels of C10orf25 and miR-671-5p. Western blot was used to detect the expression of proteins related to the NF-κB signaling pathway of 22Rv1 cells in the both groups.Results:In the GEO database, the relative expression level of C10orf25 in prostate cancer tissues was lower than that in paracancerous tissues ( P < 0.01). The relative expression levels of C10orf25 in immortalized prostate epithelial cell line RWPE-1 and prostate cancer cell lines C4-2B, DU-145, 22Rv1, PC-3, and LNCaP were 1.00±0.05, 0.63±0.04, 0.42±0.03, 0.18±0.04, 0.81±0.02, 0.50±0.07, and the difference was statistically significant ( F = 43.29, P < 0.05). The proliferation ability of 22Rv1 cells in C10orf25 group was lower than that in the control group from the second day, and the differences were statistically significant (all P < 0.05). The number of invasive cells in the control group and C10orf25 group were (97±11) and (36±9), respectively, and the difference was statistically significant ( t = 4.15, P < 0.01). Linc2GO software prediction results showed that C10orf25 had a binding site for miR-671-5p. The dual luciferase reporter gene assay showed that the relative luciferase activity of miR-671-5p and C10orf25 wild plasmid co-transfecting 22Rv1 cells was lower than that of miR-NC and C10orf25 wild plasmid co-transfecting 22Rv1 cells, and the difference was statistically significant ( P < 0.01); when miR-671-5p or miR-NC was co-transfected with C10orf25 mutant plasmid, the difference in the luciferase activity of 22Rv1 cells was not statistically significant ( P > 0.05). The relative expression levels of miR-671-5p in 22Rv1 cells were 7.33±0.99 and 0.98±0.16, respectively in the control group and C10orf25 group, and the difference was statistically significant ( t = 6.32, P < 0.01). The results of Western blot showed that the expression levels of NF-κB signaling pathway protein p50, matrix metalloproteinase 9, c-myc, and vascular endothelial growth factor protein in 22Rv1 cells in C10orf25 group were lower than those in the control group. Conclusions:The overexpression of C10orf25 may inhibit the proliferation and invasion of prostate cancer cells through the miR-671-5p-NF-κB axis.

OBJECTIVETo investigate the effect of the Uremic Clearance Granule (UCG, ), a Chinese patent medicine, on tubular epithelial-to-mesenchymal transition (EMT) in a unilateral ureteral obstruction (UUO) model in vivo and transforming growth factor (TGF)-β1 induced EMT of HK-2 cells in vitro.

METHODSIn vivo study, 50 Sprague Dawley rats were divided into three groups: a sham operation group (n=10), a UUO group (n=20), and a UUO with UCG treatment group (n=20). The UCG was given at a dose of 4.5 g/kg body weight per day by gavage after surgery. In vitro study, HK-2 cells were cultured in 10% fetal bovine serum (FBS), 10% healthy rat serum, 10% FBS and TGF-β1 (10 ng/mL), 10% healthy rat serum and TGF-β1, or 10% rat serum containing the uremic clearance granule and TGF-β1. The expression of the epithelial marker E-cadherin and the mesenchymal markers vimentin and α-smooth muscle actin (α-SMA) in kidney tissues and HK-2 cells were investigated by Western blot analysis and immunofluorescence staining.

RESULTSThe rats of the UUO group showed obvious tubulointerstitial fibrosis, compared with the sham operation group rats. Tubulointerstitial fibrosis score was reduced by 17.5%±1.1% at day 7 and by 20.0%±1.2% at day 14 in the UCG-treated group, compared with the UUO group. The UCG could maintained expression of E-cadherin and suppressed expression of vimentin and α-SMA in kidney tissues of UUO rats at days 7 and 14, as determined by Western blot analysis and immunofluorescence staining. Rat serum containing the UCG partially inhibited TGF-β1-induced fibroblast phenotype of HK-2 cells and maintained the epithelial morphology of HK-2 cells in vitro. This occurred partially through a reduction of vimentin expression and an increase of E-cadherin expression.

CONCLUSIONThese results suggest that the UCG prevents tubular EMT and may be a promising agent for treating tubulointerstitial fibrosis.

OBJECTIVE: To investigate the effects of Birinapant on hepatocellular carcinoma cells and its related molecular mechanisms. METHODS: Human hepatocellular carcinoma cells QGY-7701 were treated with 0, 1, 5, 25 and 125 nmol/L Birinapant for 24, 48 and 72 hours respectively, each experiment 3 wells.The proliferation activity of cells, the apoptosis levels, the cells nuclear type, the mitochondrial membrane potential, the transcription and expression levels of genes and the cytotoxicity of Birinapant were analyzed.At the same time, 4-week-old male BALB/C mice were randomly divided into 5 groups, with 20 mice in each group.The mice were inguinal injected with QGY-7701 cells, and then subcutaneous injected with Birinapant (concentrations ranging from 0, 1, 5, 25, 125 μg/kg) in each group after two days, once every other day.On 18 day since first Birinapant injection, 10 mice were killed in each group to weigh tumor tissue and survival time was recorded from the remaining 10 mice.The effects of Birinapant on the growth of the tumor and the survival time of tumor-bearing mice were observed. RESULTS: Compared with the negative control (NC) group, the proliferation activity of QGY-7701 was inhibited significantly after Birinapant treatment and the apoptosis levels were increased significantly (<0.01).The cell mitochondrial membrane potential was decreased and the karyotype was changed (<0.01).At the same time, the transcription and expression levels of genes cellular inhibitor of apoptosis protein 1(cIAP-1), cellular inhibitor of apoptosis protein 2(cIAP-2), ras, raf, mek and erk were significantly decreased (<0.01), while the expression levels of caspase-3 and caspase-9 genes were up-regulated (<0.01).Compared with the model group (MG), the growth of the tumor was inhibited significantly and the survival time of the tumor-bearing mice was prolonged after Birinapant treatment (<0.01). CONCLUSIONS Birinapant can inhibit the expression of cIAP-1, cIAP-2 and the proteins of Ras-Raf-MEK-ERK signal pathways, so as to activate the mitochondria mediated endogenous apoptosis pathway.Birinapant shows a certain inhibitory effect on liver cancer.
