After analyzing the clinical data of 5 injured persons diagnosed with delayed spleen or liver rupture combined with fractures after the Wenchuan earthquake, we found that the abdominal injuries in earthquake were rare but usually very severe. Since almost all the injured persons had multiple injuries, mortality was extremely high. First aid service should be applied in the first 6 to 8 hours. Orderly physical examination and peritoneocentesis in multiple sites are in favor of diagnosis. Reducing the missed diagnosis rate of abdominal injuries is important in raising the rate of successful treatment. Therapy for earthquake injuries should be focused on the most deadly injuries after a thorough examination, besides this, precise employment of control surgery, swift transportation of the injured persons, and prevention and dealing with complications are also important.

NF-κB a factor possessing multiple transcription functions, has been demonstrated to have relation with the imbalance between cell proliferation and apoptosis in stomach, intestines, liver and other tissues of digestive tract. The active NF-κB signal transduction is extensively involved in the precancerous lesion,rumor development and invasion and metastasis. The therapies aimed at the activation of NF-κB can promote apoptosis of tumor cells, reduce the resistance against chemo-radiotherapy and relieve the cachexia caused by tumor.

RT-PCR and in situ hybridization were observed during dialyzer reuse. Results Every plasma cytokine level was decreased during reuse compared with first use dialyzer, but no significant difference was found between them. The levels of gene expression of IL-1?、TNF-? and IL-6 were different from the first use significantly. Conclusion If effective dialysis volumn was maintained, formaldehyde as disinfectant on reprocessing the dialyzer may amilorate membrane bio-compatibility. It would be benificial to decrease appearance of long term hemodialysis -related complications.

Objective To summarize the experience of intraoperative rapid parathyroid hormone (PTH) detection by immunochromatography in thyroid surgery.Methods Patients undergoing thyroid surgery in Shanghai Tenth People's Hospital from Nov.2016 to Jul.2017 were collected and the clinical data including level of blood calcium,serum phosphorus and PTH,and pathological findings were analyzed.Results In this study,im munochromatographic assay was used in 45 cases (experimental group) and nano carbon method was used in 47 cases (control group).In benign cases,levels of blood calcium and PTH in experimental group were higher than those in the control group ((2.07±0.09) vs (2.04±0.06) and (3.41±1.82) vs (3.34±1.84),P＞0.05).In malignant cases,blood calcium level in experimental group was higher than that in the control group ((2.02±0.13) vs (1.99±0.38),P＞0.05) and PTH level was significantly higher than that in the control group ((2.22±1.27) vs (1.44±1.44),P＜0.05).Serum phosphorus level in experimental group group was much lower than that in the control group ((1.02±0.17) vs (1.14±0.23),P＜0.05).Conclusions Using intraoperative rapid PTH detection by immunochromatography can identify parathyroid and avoid accidental injury of parathyroid gland,which can reduce the postoperative incidence of hypocalcemia.

Objective To investigate the role of recombinant human interleukin 6 (rhlL-6) in calcification and osteogenic transition of cultured human umbilical artery smooth muscle cells (HUASMC), and the possible cell signal transduction way. Methods HUASMCs were isolated by the explant method. HUASMCs were treated with (treatment groups) or without (control group) rhIL-6. Alizarin Red S stain was applied for calcium deposition in extracellular matrix of control ceils and the cells treated with rhIL-6 50 μg/L at day 12. Calcium concentration in cell layer of control group and treatment group (treated with rhIL-6 10 μg/L and 50 μg/L, respectively) was determined calorimetrically by the o-cresolphthalein complexone method at day 3, 6, 9 and 12, and corrected by total cell proteins. The mRNA expressions of bone-specific alkaline phosphatase (BAP), osteopontin (OPN), bone morphogenetic protein-2 (BMP2) and osteoprotegerin (OPG) were estimated by real-time PCR in 12, 24 and 72 hours. OPN, BMP2 and OPG expressions were assessed by Western blotting and the BAP concentration at the same time was checked by fluorometry method . Electrophoretie mobility shift assays (EMSA) was used to detect the binding activity of transcription factor Cbfα1 with or without inhibitors of p38-MAPK (SB203580) and PKC (DHC) after 6 hours stimulation by rhIL-6 10 μg/L. Results rhIL-6 induced a positive Alizarin Red S stain and a time-dose-dependent increasing of cell layer calcium deposition.Compared with control group, rhIL-6 10 μg/L enhanced gene expression and protein levels of BAP and BMP2 at the early time (12 and 24 hours), and of OPN and OPG at later hours (24 and 72 hours). RhIL-6 still induced an increasing of binding activity of Cbfα1, which could be partially blocked by DHC but not SB203580. Conclusions rhIL-6 induces HUASMCs calcification and osteogenie transition in vitro, which may be one of the mechanism involved in IL-6 associated vascular calcification as observed in clinical studies. The role of IL-6 in HUASMCs may partially achieved through the PKC cell signal transduction way.

ObjectiveTo investigate the effects of pravastation intervention on tumor necrosis factor (TNF)-α-indueed ossifie calcification in human umbilical artery smooth muscle cells (hUASMCs). MethodshUASMCs were cultured by tissue explant in vitro, hUASMC were treated with TNF-α 50 μg/L and pravastatin of three different concentrations. The calcium deposition was determined by O-cresolphthalein eomplexone method. The mRNA expression of BAP and OPN was determined by real time-PCR. The protein expression of BAP, OPN and BMP-2 was determined by Western blotting. ResultsPravastatin inhibited the proliferation of hUASMC (r=-0.946, P＜0.01) and decreased the cell calcium deposition (r=-0.973, P＜0.01) in a dosedependent manner. Pravastatin down-regulated the expression of BAP, OPN and BMP-2 induced by TNF-α in a dose-dependent manner (mRNA, r=-0.972, P＜0.01;BAP protein, r=-0.820, P＜0.01;OPN protein, r=-0.972, P＜0.01;BMP-2 protein, r=-0.928, P＜0.01). ConclusionPravastatin can inhibit the proliferation of hUASMC, decrease the cell calcium deposition and inhibit the ossifie calcification of hUASMC induced by TNF-α.

Objective To study the effect of uremic serum on the calcification and osteogenic transition of cultured human umhilical artery smooth muscle cells(HUASMC).Methods Sera from 40 healthy controls(control group),40 nondialysis uremic patients(nondialysis group)and 45 uremic patients on dialysis(dialysis group)were detected fi)r biochemical indexes concerned and used to treat the cultured HUASMC.Alizarin red S stain was applied to examined calcium deposition in the cell layer.Calcium concentration was determined calorimetrically by the Ocresolphtha]ein complexone method,and corrected by total cell proteins.The mRNA expression of bone specific alkaline phosphatase(BAP),osteopontin(OPN)and bone morphogenelic protein 2(BMP2)was estimated by realtime PCR.OPN and BMP2 protein expression was assessed by Western blotting and fluorometry method was used to check the BAP concentration. Results Serum biochemical detection revealed thai both uremic groups had higher levels of phosphate,triglyseride,iPTH,C-reactive protein(CRP)and IL-6,and lower level of fetuin-A than healthy control(P＜0.05).Furthermore,dialysis serum had higher levels of triglyseride,CRP and IL-6 than nondialysis serum(P＜0.05).Compared with control group,both uremic scra induced more cell layer calcium deposition and higher mRNA and protein expression levels of BMP2,BAP and OPN(P＜0.05).Higher mRNA and protein expression levels of above factors were found in dialysis group as compared to nondialysis group(P＜0.05). Conclusions Uremic serum can induce HUASMC calcification and osteogenic transition in vitro,which may be one of the mechanisms involved in vascular calcification of ESRD patients.Microinflammatory state may promote the osteogenic transition and vascular calcification in dialysis patients.

Objective To investigate the markers in early diagnosis of acute kidney injury (AKI) in patients undergoing heart surgery.Methods Markers included serum cystatin C (CyC),and urinary neutrophil gelatinase-associated lipocalin(NGAL),interleukin 18(IL-18),retinol binding protein(RBP)and N-acetyl-β-D-glucosaminidase(NAG).Twenty-nine cardiac surgical patients hospitalized were enrolled in the study.Serial blood and urine samples were collected immediately before incision and at various time intervals after surgery.The primary outcome measure was AKI.defined as a 50%increase in Scr from baseline. Results The cohort consisted of 29 patients aged(62.9±13.7)years,and baseline Scr was(73.2±11.9)μmol/L.There were no significant differences in demographics between cases and controls,while the aortic clamp time was predictably longer in AKI cases as compared to controls[(60.63±13.92)vs(43.00±9.20)rain,P<0.05].Each biomarker difiered significantly between cases and controls at least one timepoint.Optimal AUCs were for CyC at 10 houm with sensitivity (ST)0.71,specificity(SP)0.92,AUC=0.83(0.67-1.00),cut-off(CO)1.31 mg/L;NGAL at 0 hour with ST 0.84,SP 0.80,Auc=0.85(0.70-1.00),CO 49.15 μg/g Ucr;IL-18 at 2 hours with ST 0.85,SP 0.73,AUC=0.81(0.64-0.97),CO 285.65 ng/g Ucr;RBP at 0 hour with ST 0.75,SP 0.67,AUC=0.77(0.60-0.95),CO 2934.65μg/g Ucr and NAG at 4 hours with ST 0.86,SP 0.67,AUC=0.72(0.53-O.92),CO 37.05 U/mg Ucr.Using a combination of all the 5 biomarkers analyzed at the optimal time-point as above,an AUC of 0.98(0.93-1.02)(P<0.01)in this limited sample was able to obtain. Conclusions Application of serum and urinary biomarkers for the prediction of AKI in patients undergoing cardiac surgery is highly dependent on the sampling time.Of the evaluated markers,uNGAL has the best predictive profile.uRBP also shows similar predictive power.Combining all the five above biomarkers is able to predict significantly more cases,suggesting that the use of more than one marker may be beneficial clinically.

OBJECTIVE: To study the expression of angiopoietin receptor Tie-2 in the renal tissue of diabetic rats and the effects of Astragalus. METHODS: SD rats were randomly divided into normal control group, diabetes group and Astragalus-treated group. The expression of receptor Tie-2 in the renal tissue was assessed by using real-time quantitative polymerase chain reaction and immunohistochemical method. RESULTS: Glomerule Tie-2 protein expression was significantly elevated in the diabetes group as compared with the normal control group (P<0.01). Glomerule Tie-2 protein expression in the Astragalus-treated group was decreased as compared with the diabetes group (P<0.01). CONCLUSION: Tie-2 may play an important role in the pathogenesis of the early stage diabetic renal injury. The reno-protection effect of Astragalus may be mediated by down-regulating the expression of Tie-2 in the kidney tissue of diabetic rats.
