Objective To investigate the effects of ulinastatin on pulmonary and hepatorenal function of elderly patients undergoing resection of esophageal cancer. Methods The clinical data of 40 elderly patients with esophageal cancer who had been admitted to Southwest Hospital from January 2005 to January 2008 were retrospectively analyzed. All the patients were randomly divided into control group (n = 20) and ulinastatin group (n = 20) according to random number table. Patients were administered with total parenteral nutrition, and patients in ulinaslatin group were additionally instilled with 4×10~5 U/d of ulinastatin. The levels of PaO_2, PaCO_2, PaO_2/FiO_2, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (Tbil), blood urea nitrogen, creatinine and uric acid were detected preoperatively and at postoperative day 2 and day 6. All the data were analyzed by t-test and chi-square test. Results The levels of PaO_2 and PaO_2/FiO_2 were (87.3±4.2) mm Hg (1 mm Hg =0.133 kPa) and (416±20)mm Hg in ulinastatin group, which were significantly higher than (79.0±4.3)mm Hg and (376±20)mm Hg in control group (t =6.2, 6.2, P <0.05). The levels of ALT, AST and Tbil were (23±7)U/L, (38±8)U/L and (13.4±3.0) μmol/L in ulinastatin group, and (39±8) U/L, (50±9) U/L and (24.5±6.0) μmol/L in control group, with significant difference between the 2 groups (t = 7.0, 4.4, 7.6, P < 0.05). The levels of uric acid, blood urea nitrogen and creatinine were (279±84) μmol/L, (4.1±1.7) mmol/L and (66±12) μmol/L in ulinastatin group, and (386±67)μmol/L, ( 8.9±2.7) mmol/L and (95±38) μmol/L in control group, with significant difference between the 2 groups (t = 4.4, 6.4, 3.3, P < 0.05). The recurrence of complications in ulinastatin group was significantly lower than that in control group (χ~2 = 4.8, P <0.05). Conclusion Postoperative supplementation of ulinastatin and total parenteral nutrition is helpful in improving the pulmonary and hepatorenal function of elderly patients undergoing resection of esophageal cancer.

Objective To establish the quality standard of Yuling Tea for its quality control. Methods Astragalus, Fructus cnidii L, Schisandra chinensis and Lycii Fructus in Yuling Tea were identified by TLC. The content of Schisandrin was determined by HPLC. Welch Materials C18 column (250 mm×4.6 mm, 5 μm) with mobile phase of methanol-water (70∶30) was used. The detective wavelength was 250 nm. Results The TLC for identification was simple and special. Schisandrin showed a good linear relationship in 0.222-0.222 0 μg, r=0.999 9. The average recovery was 98.96%, and RSD was 0.74%. Conclusion The method can accurately determine the content of Schisandrin in Yuling Tea. It can be used for quality control of the preparation.

Objective In order to explore practical values of the revised Duck criteria for diagnosis and treatment of pediatric infective endocarditis(IE).Methods Seventy-three children′s cases diagnosed and treatmented as IE complicated with congenital heart defects in the past 22 years were collected to make retrospective analysis according to the Duck criteria.Results In 73 patients,a definite diagnosis of IE was made in 37 patients(51%),16(43%) of which proved by the pathologic lesions during the operations.Eight patients(22%) met two major criteria,13 patients(35%) met one major and more than 3 minor criteria.36 patients(49%) were diagnosed as possible IE.Forty-five patients(62%) were cured using antibiotic therapy.Sixteen cases(21%) were failure in antibiotic treatment,of whom 16 patients were operated by cutting off the detection of vegetation and repairing the heart malformation.Tweleve cases(17%) were died,one of which was died after the operation.Conclusions IE is still a significant complication of congenital heart disease.Duck criteria is relative rigid in sensitivity,but it is high in specificity.When the vegetation isn′t large enough in shape,revised Duck criteria is difficult to(diagnose) early.The surgery treatment is optimistic.To combine the medicine with surgery can contributed to decrease mortality rate.

Objective To establish a newborn animal model of renal injury caused by intrauterine asphyxia and explore the mechanism of renal injury in neonate after asphyxia.Methods After two-horn uterus and vessels supplying uterus and ovary were exposed in 21-day-pregnant Wistar rats,arterial clamp occluded one side of vessels.The occluding time were 10 and 30 minutes.Then arterial clamp was taken off,and reperfusion for 30 minutes,2,6,12 and 24 hours respectively.Reaching prescribed time uterus horn was opened rapidly and pups were removed.The pups sacrificed by decapitation.Kidneys were taken out and studied by HE staining and electron microscope.Results Kidney of fetal rats in 21 gestational age was developmental and mature degree of tubules dropped behind that of glomerule.Changes of proximal tubules were early and serious compared with distal tubules during ischemia and reperfusion stages.Conclusion Ischemia and reperfusion to graded pregnant rat can supply an ideal model to study injury of kidney and other organs(intraute)-rously.

OBJECTIVETo explore the effect of Bushen Huoxue Compound (BHC) on lactate dehydrogenase (LDH) leakage, expressions of vascular endothelial growth factor (VEGF) and VEGF mRNA in retinal Muller cells under high glucose condition or advanced glycosylation end products (AGEs) condition by using serum pharmacological method.

METHODSThe retinal Müller cells of 5-7 days post-natal Sprague Dawley (SD) rats were cultured with modified enzyme-digestion method. Purified retinal Muller cells were cultured in normal conditions, high glucose condition (50 mmol/L) or AGEs (50 mg/L and 100 mg/L) conditions, and BHC-containing serum was added to culture medium. The LDH leakage and VEGF expressions were measured by enzyme-linked immunosorbent assay (ELISA). In addition, the relative expression of VEGF mRNA was tested by reverse transcription polymerase chain reaction (RT-PCR).

RESULTSCompared with the normal control group, expressions of VEGF and VEGF mRNA were significantly increased in the high glucose group, the low dose AGEs group and the high dose AGEs group (all P < 0.01). The LDH leakage was obviously increased in the high dose AGEs group, when compared with the normal control group and the high glucose group (P < 0.01). The LDH leakage, expressions of VEGF and VEGF mRNA were obviously decreased by BHC-containing serum both in high glucose and AGEs conditions (P < 0.05, P < 0.01). BHC-containing serum had no significant effect on the LDH leakage and expressions of VEGF and VEGF mRNA in normal conditions (P > 0.05).

CONCLUSIONSAGEs intervention could obviously lower the stability of Müller cell membrane. Up-regulated expressions of VEGF and VEGF mRNA in cultured Müller cells could be induced by AGEs or high glucose. BHC-containing serum could stabilize the stability of Müller cell membrane, inhibit the transcription of VEGF mRNA and decrease the protein expression of VEGF, which might be one of important mechanisms for preventing and treating diabetic retinopathy.
