Objective To assess the clinical efficacy of percutaneous transhepatic portal embolization (PTPE) before the extended right hemihepatectomy for the treatment of hilar cholangiocarcinoma. Methods We successfully carried out a percutaneous transhepatic portal embolization in a patient with hilar cholangiocarcinoma and liver cirrhosis. Hepatic hemodynamics, liver volume,liver functions, and pathological changes were recorded after the procedure. Results After PTPE, the patient developed an inflammatory response manifested by a transient fever (39.2 ℃ at peak on the 5th postoperative day) and a mild abdominal pain. There were no other complications such as nausea, vomitting, hemorrhage, or bile leakage. The volume of the left lobe increased from 417.0 ml to 522.4 ml (enlargement rate, 125.2%); the volume of the right lobe decreased from 1041.3 ml to 1017.4 ml (diminishment rate, 97.7%). The ratio of the left lobe to the whole liver increased from 28.6% to 33.9%. The velocity of blood flow of the left portal vein increased by 100% and 39% on the day of operation and the 6th day after operation, respectively (from 12.8 ml/s preoperatively to 23.2 ml/s and 17.1 ml/s). The values of ICG R15 and ICG-K returned to normal levels. On the 17th day after PTPE, the quantity of bile drainage from the left lobe exceeded that from the right lobe. The extended right hemihepatectomy was performed 34 days after PTPE. During operation, an obvious hypertrophy of the left lobe and a distinct demarcation line between the segment 5, 6, and 7 (S5,6,7) and other segments were observed. Postoperative recovery was uneventful. The pathological examination found stenosis and embolization of the portal vein, as well as the degeneration, necrosis, and apotosis of the liver cells in the embolized lobe. Conclusions Portal vein embolization can effectively induce the hypertrophy of the unembolized lobe, which increases the safety level of following extended hemihepatectomy in patients with impared liver functions.

As introduced in the paper,Australian government subsidize the public hospitals with all their budget needs as compensation,with the two levels of governments constituting the largest buyer of health products and services in the country.In addition,the government supports the hospitals with their facilities.A rational government investment mechanism is proposed with reference to such a model for the ongoing reform of public hospitals in China.

A review of the system background for the multi-institution physician practice in China,and an analysis for the specific constraints for physicians of public hospitals to embrace such a practice On this basis, the paper probed into the measures to encourage the physicians for doing so. The measures recommended include advanced design, improvement of the quality of care and safety mechanism,incentives mechanism, mandatory enforcement of medical liability insurance to minimize risk exposure of such a practice, aiming at advancement of this practice.

Objective: To study whether the orientation behavior of rats is affected by multi-sensory information. Methods: SD rats were randomly divided into 2 groups: the audio-visual integration group and pure audio group. The orientation behaviors of rats were observed after given single modal and multi-modal sensory cues with spatial disparities. Results: We found that when the temporal and spatial audio cues were coincident to a target visual cue, the rats had a markedly reduced reaction time and increased success rate in orientation behaviors; there was an obvious audio-visual integration effect. The integration effect was more obvious when the intensity of target visual cue was weak, with the enhancement efficiency being (87.3 ± 8.5)%, significantly higher than that when the intensity of target visual cue was stronger (27.6%, P< 0.05). Conclusion: Rat auditory-visual integration behaviors also follow the multi-sensory integration rules.

Objective To explore how to determine the designated hospitals for critical illness scientifically and reasonably.Methods Analyzing the choice of medical providers by inpatients with critical illness,by means of the database of NRCMS in 2009～2010 in one county,Guangxi province.And analyzing the current policies on the basis of general principals used in health policy analysis.Results The choices of medical providers made by inpatients with critical illness are influenced by various factors.Choice of such hospitals should only be dependent on scientific and reasonable determination of patients' reasonable medical needs,instead of on the medical competency of the hospitals only.Conclusion Maximal cost-effectiveness should prevail,be it the class-1 demand of complete healing which is highly dependent on medical technology,or class-2 demand requiring repeated hospitalizations and not highly dependent on medical technology.Reasonable designation of hospitals for critical illness should be based on reasonable medical needs of patients,instead of medical competency of hospitals only.

Salsola collina is widely distributed in droughty and semi-droughty area, which is used as a kind of folk remedy in traditional Chinese medicine for treatment of hypertension. The study is on the chemical constituents of this herb from its aerial parts to obtain its active constituents. Dried and crushed aerial parts of this herb were extracted three times with 95% EtOH at reflux. The ethanol extracts were combined and concentrated under reduced pressure at 70 ℃ to yield residue, which was suspended in water and successively partitioned with light petroleum, chloroform and n-butanol. The chloroform and n-butanol fractions were treated by various chromatographic techniques, such as silica gel, C18 reversed-phase silica gel and macroporous resin column chromatography. Compounds were elucidated by their physicochemical properties and spectroscopic analysis. In the course of our study on searching biological active components from this herb, a new alkaloid together with three known alkaloids were isolated and identified as N-transferuloyl-3-methyldopamine (1), 3-[4-(β-D-glucopyranosyloxy)-3- methoxyphenyl]-N-[2-(4-hydroxyl-3-methoxyphenyl)ethyl]-2-propenamide (2), salsoline A (3), salsoline B (4). Compound 4 is a new compound and named as salsoline B, while compound 2 was obtained in Salsola collina for the first time.

Objective To explore the risk factors for hepatitis B virus (HBV) intrauterine infection to provide a scientific ev idence for itsprevention.Methods Three hundred and twelve pregnant women of HBsAg positive screened from April 2013 to May 2015 served as the research subjects and were followed up until 6 months after birth.The infantile mothers of HBsAg and/or HBV DNA positive were selected as the intrauterine infection case group,while other mothers served as the control group.The Logistic regression analysis was adopted to analyze the risk factors for intrauterine HBV infection.The questionnaire survey method was used to collect the basic data and time-resolved immunofluorescence assay was used to detect HBsAg.PCR was adopted to measure level of HBV DNA and automatic biochemistry analyzer was used to measure the hepatic functional parameters including ALT,AST,triglyceride and cholesterol.Results The single factor analysis results indicated that HBeAg,HBV DNA,contamination of amniotic fluid and sexual behavior during pregnancy were related to HBV intrauterine infection(P＜0.05).The multiple variate Logistic regression results showed that positive HBeAg(OR=2.76,95 ％ CI=1.19-7.94),positive HBV DNA(OR=9.62,95 ％ CI=2.58-35.33),and sexual behaviors during pregnancy (OR =1.53,95 ％ CI =1.07-6.40) were the risk factors for intrauterine HBV infection.Conclusion Pregnant women with positive HBeAg,positive HBV DNA and sexual behavior during pregnancy may be the high risk factors for neonatal intrauterine HBV infection.
