OBJECTIVETo explore the clinical effects of colonic dripping with Taihuang liquid (THL) in treating neonatal hyperbilirubinemia (HBE).

METHODSOne hundred and thirty-eight neonates with HBE were randomly assigned to two groups. Conventional treatment and nursing were given to both groups, and THL was given additionally to the observation group by colonic dripping.

RESULTSSignificant differences between the observation group and the control group were shown in frequency of defecation (4.6 +/- 1.3 times/d vs 2.0 +/- 1.1 times/d), daily serum bilirubin reduction (31.5 +/- 10.1 micromol/L vs 23.3 +/- 8.3 micromol/L), and days for normalizing serum bilirubin level (5.6 +/- 3.5 d vs 7.8 +/- 4.1 d, all P < 0.01).

CONCLUSIONColonic dripping of THL could promote the excretion of bilirubin, so as to decrease the level of serum bilirubin in neonates with HBE.

The aim of this study was to investigate the effect of urotensin II (U II) on the nitric oxide (NO) production in cultured neonatal rat cardiomyocytes. The endothelial nitric oxide synthase (eNOS) mRNA expression was assessed by semi-quantitative reverse transcription-polymerase chain reaction. The activity of nitric oxide synthase (NOS) and NO content in cardiomyocytes were measured. The current results showed that U inhibited eNOS mRNA expression, the NOS activity and the NO production of cardiomyocytes. U II (0.1 micromol/L) inhibited the NOS activity and the NO production in cardiomyocytes in a time-dependent manner. These results suggest that the cardiovascular effect of U II might be partially associated with NO production in cultured neonatal rat cardiomyocytes.

Methods: The recombinant anti-HER2 ScFv/tBid gene was cloned into vector pCMV and the recombinant plasmid was transfected into SGC7901 cells. The gene expression was detected by RT-PCR and immunofluorescent staining. Cell counting was carried out to show the effect of the gene transfection on cell growth. At the same time, significant apoptotic peak was detected by flow cytometry in recombinant anti-HER2 ScFv/tBid gene transfected cells. Results: The fusion protein of anti-HER2 ScFv/tBid was observed in the cytoplasm of transfected SGC7901 cells. The transfected cells displayed typical cell growth inhibition and apoptosis. Conclusion: Fusion protein of anti-HER2 ScFv/tBid can induce apoptosis of SGC7901.

OBJECTIVETo study the strategy of applying molecular genetic methods and techniques in the diagnosis of spinocerebellar ataxias (SCA).

METHODSThis study included 43 patients with SCA from 36 families, 38 sporadic SCA patients, 60 healthy individuals from the SCA families and 44 normal controls. The trinucleotide repeats were detected by polymerase chain reaction (PCR), denaturing polyacrylamide gel electrophoresis and silver staining technique. The repeat numbers were calculated by software.

RESULTSSCA3 was the most common type in the Hans of south China, accounting for 42.0%, followed by SCA2 (7.4%), SCA1 (4.9%), SCA7 (3.7%), SCA6 (2.5%) and SCA12 (1.2%). No patient was found to have SCA8, SCA10, SCA17, and dentatorubro-pallidoluysian atrophy(DRPLA).

CONCLUSIONMolecular genetic detection is an effective way to confirmation of SCA subtype diagnosis and presymptomatic genetic diagnosis.

Objective To explore the effect of evidence-based nursing during preoperative interview for abdominal surgery patients' recovery after general anesthesia. Methods 124 patients who accepted selective operation on abdominal region were randomly divided into evidence-based group and control group, 62 cases ineach group. On the base of routine method in the preoperative interview, the evidence-based group established evidence-based information supporting system, which aimed to dredge the psychological stress of the patients'response to surgery individually and intervene by demonstrating simulation of operation process. According to the traditional way, control group accepted routine preoperative interview. To compare patients' indexes of two groups before and after anesthesia. Results Patients' heart rate and the mean arterial pressure lower than control group before anesthesia in evidence-based group. The dosage of midazolam in evidence-based group was less than the control group (t =6. 73,7. 24,8. 17;P <0. 05). The difference of pre-anesthesia anxiety scores was statistically significant between evidence-based group and control group (t =7. 68 ,P <0. 01 ). But the difference of the anxiety scores after operation wasn' t statistically significant between two groups ( t = 0. 62, P > 0. 05 ). Patients in evidence-based group took shorter revival time than control group ( t = 9. 71,10. 45,11.32 ; P < 0. 01 ). Compared the different period pain score of two groups, patients of evidence-based group were lower than those of the control group, and the patients' satisfaction scores also were higher than those of control group, the differences were statistically significant (t =2. 38,5. 22,2. 63,7. 62;P <0. 05). Conclusions Application evidence-based nursing information support in preoperative interview effectively relieves the preoperative anxiety, can reduce the dosage of narcotic and sedative drugs, shorten the revival time, improve patient' s satisfaction and have reached the antieipant effects.

OBJECTIVETo investigate the role of multidrug resistant protein 2 (MRP2) and glutathione (GSH) cotransport system in hepatic arsenic metabolism in rats.

METHODSThirty healthy Wistar rats were divided randomizedly into five groups. The first group was the control group and the rats in this group were administered with normal saline. In the second, third and fourth group the rats were administered with 4, 10 and 20 mg As(+)3/kg BW of sodium arsenite respectively every other day for two weeks. The fifth group was the benzene-soluble organics (BSO) intervention group and in this group the rats were administered with 2 mmol/kg BW BSO intraperitoneally every day three days before the end of the experiment. The other treatment was the same as in other groups. All rats were sacrificed two weeks after the treatments. Arsenic contents in bile, liver and blood were detected by atomic absorption spectroscopy (AAS), and the expression of MRP2 in the membrane of hepatocyte was determined by Western-blot analysis.

RESULTSThe level of total arsenic (including organic arsenic and inorganic arsenic) in bile, liver and blood in all three different dose groups was higher than those in the control groups (P < 0.05). Arsenic levels of bile and liver were increased with intragastric arsenic dose. Blood arsenic levels were not significantly different in three different dose groups. Expression of hepatic MRP2 was increased with intragastric arsenic concentration. A positive correlation between biliary arsenic concentration and MRP2 levels was found in liver (r = 0.986, P < 0.05). For the rats pretreated with BSO, the biliary arsenic was significantly higher than that in the control group but lower than that in the high dose group; the liver and blood arsenic was higher than that in the control group and in the high dose group. Expression of MRP2 pretreated with BSO was decreased.

CONCLUSIONSodium arsenite can induce expression of MRP2 and the up-regulation of MRP2 may play an important role in the bile secretion of arsenite and its metabolites. The function of MRP2 for transportation of arsenic and its metabolites is associated with the intracellular GSH level. BSO inhibits the synthesis of GSH, which weakens the function of the MRP2-GSH cotransport system and makes the liver arsenic increased.

OBJECTIVE: We wanted to describe the computed tomography (CT) findings of gallbladder tuberculosis (TB) and to correlate them with pathologic findings. MATERIALS AND METHODS: There were seven patients (M:F = 3:4; mean age, 46.3 years; age range, 32 to 78 years) in whom gallbladder TB was eventually diagnosed. All of them underwent cross-sectional imaging with CT, a pathologic examination and a retrospective review. CT imaging evaluation was done in each case, including the findings of a mass versus nodule, wall thickening (uniform or irregular) and the enhancement patterns (homogeneous or heterogeneous). RESULTS: All the cases of gallbladder TB revealed the following three different CT findings: micronodular lesion of the gallbladder wall (n = 1), a thickened wall (n = 4) and a gallbladder mass (n = 2). There were three cases of homogeneous enhancement of the lesions, including homogeneous enhancement with nodular lesion, homogeneous uniform thickness enhancement and homogeneous thickness enhancement in one case each, and these cases pathology showed tuberculous granuloma with a little caseating necrosis in one case and tuberculous granuloma with rich fibrous tissue, but little or no evident caseating necrosis in two cases. Four cases of heterogeneous enhancement of the lesions, including heterogeneous uniform-thickness enhancement in two cases, heterogeneous enhancement with a local mass lesion in one case and heterogeneous enhancement with a mass that replaced the gallbladder in one case; in these cases, pathology showed tuberculous granuloma with marked caseation or liquefaction necrosis in three cases and tuberculous granuloma by fibrous and calcifications accompanied by caseating necrosis in one case. Among the seven cases of gallbladder TB, six cases were accompanied by abdominal extra-gallbladder TB, including abdominal lymph node TB in five cases and hepatic TB in four cases. CONCLUSION: Gallbladder TB has various CT manifestations, and the enhanced CT findings are well matched with pathological features. An irregularly thickened gallbladder wall or a gallbladder wall mass with multiple-focus necrosis or calcifications accompanied by the typical CT findings of abdominal extra-gallbladder TB should suggest the diagnosis of gallbladder TB.

OBJECTIVETo provide right time points in selection of right aged animals and the normal physiological data of TX mice.

METHODS7-12 months old TX and DL mice were studied, each group contained 3 female and 3 male mice of TX or DL mice. The concentration of copper in the serum, dry tissues (liver, brain and kidney), together with copper biochemistry indexes were measured. The liver histopathology was observed under light microscopy and electron microscope.

RESULTSTransaminase increased significantly only in 10 and 11-month- old (AST(TX10) = 218.3 U/L, AST(TX11) = 197.5 U/L, AST(DL10) = 171.5 U/L, AST(DL11) = 165.0 U/L, P(10) less than 0.001, P(11) = 0.022), but the copper concentration of liver, brain and kidney was significantly increased during 7-12 month old (the average concentration of copper, Liver(TX) = (750.0 +/- 85.5) mg/kg, Brain(TX) = (39.7 +/- 2.2)mg/kg, Kidney(TX) = (29.8 +/- 5.0) mg/kg, Liver(DL) = (11.6 +/- 1.5) mg/kg, Brain(DL) = (16.8 +/- 0.9) mg/kg, Kidney(DL) = (14.2 +/- 1.0) mg/kg, t = 21.16, 23.60, 7.47, for all these organs P less than 0.05).

CONCLUSIONTX mice is a suitable model of liver disease with natural recovery, so selecting animal model of suitable time point is very important.
