Three cases of renal pelvic neoplasm associated with staghorn calculi were enrolled to the study from March 2015 to June 2019. All patients underwent minimally invasive procedures previously including extracorporeal shock wave lithotripsy (ESWL), flexible ureteroscopic lithotripsy(FURL), or percutaneous nephrolithotripsy (PCNL). 3 patients of renal pelvic neoplasm with giant staghorn calculus were diagnosed by resection biopsy during laparoscopic pyelolithotomy intraoperatively and then treated by laparoscopic radical nephroureterectomy (LRNU). Case 1 was identified retroperitoneal lymph node metastasis 16 months after operation. Case 2 and 3 remained disease free. The timely diagnosis of renal pelvic neoplasm associated with staghorn calculi is always difficult, nevertheless, the laparoscopic pyelolithotomy with resection biopsy intraoperatively can be more effective in selected cases compared with routine endoscopic biopsy.

OBJECTIVE:To study the influence of oscillator on the cleanliness of class 100 clean bench in PIVAS. METH-ODS:Using sedimentated bacteria and the number of dust particle as index,in common drug configuration room,antibiotics con-figuration room and risk drugs configuration room including biological safety cabinet and horizontal laminar flow,the cleanliness of class 100 clean bench were monitored when oscillator was set at clean bench and different positions in work and non-working state. RESULTS & CONCLUSIONS:In working and non-working state of oscillator,there was no difference in sedimentated bacteria and the number of dust particle which was in line with the requirements of 2010 edition of GMP,i.e. the application and location of oscillator didn't influence the cleanliness of class 100 clean bench. From a view of safety,it is suggested to place the oscillator in the left(or right)posterior wall of clean table when biological safety cabinets is used to dispense antibiotic and risk drugs.

Objective To investigate the efficacy of the indocyanine green (ICG) clearance test (ICGR15) combined with the model for end-stage liver disease (MELD) for assessing the short-term prognosis of patients with liver failure.Methods Eighty patients with liver failure were analyzed retrospectively.ICGR15 and relevant clinical data within 24 hours of diagnosis were analyzed.Meanwhile,the MELD score and King's College Hospital (KCH) were evaluated.All findings were tested for correlation with 3-month mortality.Quantitative data were analyzed with analysis of variance and Student's t-test.Count data were analyzed with chi-square test.Correlation analysis was performed with Pearson's coefficient test.Results Among 80 patients with liver failure,39 patients survived and 41 died.The mortality rate of all patients was 51.2％.The serum total bilirubin,creainine concentrations,ICGR15,MELD scores and patient number in accordance with KCH criteria of surviving patients were (288.0±109.1) μmol/L,(63.3±24.4) μmol/L,(48.1±10.2)％,20.6±4.4,and 6 cases,respectively,which were lower than those in dead patients [(340.7 ± 108.2) μmol/L,(98.8 ± 59.1) μmol/L,(60.2 ± 10.6) ％,26.9 ± 7.1 and 19 cases,respectively] (P =0.033,P＝ 0.001,P＝ 0.000,P＝ 0.000 and P =0.003,respectively).There was no significant difference of ICGR15 among four types of liver failure.A positive correlation was observed between ICGR15 and MELD score (r=0.289,P=0.009).The ICGR15-MELD model was created by subjecting ICGR15 and MELD scores to Logistic regression analysis.The following ICGR15-MELD model,Logit (P) =0.105 × ICGR15 + 0.178 × MELD score-9.734,was constructed by Logistic regression analysis.The area under the receiver operating characteristic (ROC) curve was 0.860 and the cut offpoint of 0.3 had sensitivity of 85.40％ and specificity of 74.40％.The area under the curve of the ICGR15-MELD model was significantly higher than those of ICGR15 (0.791),MELD score (0.770) and KCH criteria (0.655).Conclusions ICGR15 and MELD scores perform better than the KCH criteria in predicting the prognosis of liver failure.The ICGR15-MELD model is superior to ICGR15,MELD score,and KCH in predicting the short term prognosis of patients with liver failure.

In order to clarify the chemical constituents in Qiliqiangxin capsule, a rapid ultra-performance liquid chromatography/orthogonal acceleration time-of-flight mass spectrometry (UPLC-Q-TOF/MS(E)) method was established. Forty peaks were identified on line using this method. The herbal sources of these peaks were assigned. The results implied that triterpenoid saponins, flavonoid glycosides, C21-steroids and phenolic acids were included in the main components of Qiliqiangxin capsule. The method is simple and rapid for elucidation of the constituents of Qiliqiangxin capsule and the results are useful for the quality control of Qiliqiangxin capsule.

OBJECTIVETo study the role of endoplasmic reticulum stress (ERS) in acute liver failure (ALF) using a mouse model of D-Galactosamine/lipopolysaccharide (D-GalN/LPS)-induced ALF.

METHODSThe ALF model was established by administering intraperitoneal (i.p.) injections of D-Ga1N (700 mg/kg) and LPS (10 mug/kg) to six C57BL/6 mice. Three of the modeled mice were also administered 4-phenylbutyrate (4-PBA; 100 mg/kg i.p.) at 6 hours before the onset of ALF and served as the intervention group. Non-modeled mice served as controls. All mice were analyzed by western blotting and qRT-PCR to determine the expression levels of ERS-related proteins in liver tissue. Liver function was assessed by measuring levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum. Extent of injury to the liver tissue was assessed by hematoxylin-eosin staining and histological analysis. qRT-PCR was also used to detect differences in expression of inflammation-related genes, and western blotting was also used to detect differences in expression of the apoptosis related protein Caspase-3.The extent of apoptosis in liver tissue was assessed by TUNEL assay.

RESULTSThe ERS markers GRP78 and GRP94 showed increased expression at both the gene and protein levels which followed progression of ALF. The ERS effector proteins XBP-1, ATF-6 and IRE 1 a involved in the unfolded protein response were activated in the early stages of ALF, and the ERS-induced apoptosis regulators Caspase-12 and CHOP were activated in the late stage of ALF. Inhibition of ERS by 4-PBA intervention protected against injury to liver tissue and function, as evidenced by significantly lower levels of serum ALT and AST and a remarkably decreased extent of histological alterations. Furthermore, the inhibition of ERS suppressed expression of the proinflammatory cytokines TNFa, IL-6 and IL-1 β, and reduced the extent of hepatocyte apoptosis.

CONCLUSIONERS is activated in the mouse model of D-GalN/LPS-induced ALF. Inhibition of ERS may be protective against liver injury and the mechanism of action may involve reductions in inflammatory and apoptotic factors and/or signaling. Therefore, inhibiting ERS may represent a novel therapeutic approach for treating ALF.

Objective To investigate the feasibility of inserting and detaining nasointestinal feeding tube in small bowl guided by bedside ultrasound(US)in critically ill elderly patients.Methods This was a retrospective study.Sixty four aged patients(≥ 60 years)in general ICU,the Second Affiliated Hospital of Jiaxing College,received the US-guided nasointestinal feeding tubes inserting and detaining.Feeding tubes passed through nasal and went into the stomach by manual blind method.Under US-guiding condition,the tube passed through the pyloric sphincter and further into the duodenum or jejunum.Finally the correct position of the tube head was assessed by bedside X-ray examination.Results The US-guided nasointestinal feeding tube-detaining technique was successfully operated in 57 patients(89.1％).The feeding tube heads were in the duodenum in thirty four cases(53.1 ％),and in proximal jejunum in twenty-three cases(35.9％).The untoward reaction included the bleeding of nasal cavity in 1 case,and hypotension in another case.Conclusions Bedside US-guided nasointestinal feeding tube placement is safe and feasible in aged critical patients.
