Objective To investigate the imaging feature of Chinese familial BCS, and to evaluate the efficacy of interventional treatment for Chinese familial BCS. Methods Angiography was taken in 4 familial BCS patients(from families A and B), and PTA was attempted in 2 of 4 patients, stents were placed in another 2 patients. Results Sisters in family A and sisters in family B had membranous obstruction of the inferior vena cava(MOVC) and segmental obstruction of the inferior vena cava(SOVC), respectively. PTA was attempted in younger sisters of the two families, stent was implanted in elder sisters of the two families. Patency of inferior vena cava and clinical symptom improvement were noted in 4 patients after interventional treatment. Restenosis was detected by angiography in sisters of family A after follow up 2 years later, and stenting was performed in the elder sister, PTA was performed in the younger sister once again. The elder sister was dead after the second stenting, and the younger sister had no symptom up to now. Sisters in family B had no restenosis after 4 years′ follow up. Conclusion 1.Lesion types of Chinese familial BCS were varied. 2.Vena cava thrombosis is the etiology of Chinese familial BCS .3.PTA, stenting and long time anticoagulation treatment may be effective methods in the treatment of familial BCS.

Objective To observe the effect on the patients of diabetes mellitus and cerebral infarction in terms of level of blood rheology and endothelin after using both intravenous low intensity laser irradiation (ILILI) and traditional Chinese medicine Tangnaoluotong in the treatment. Method Ninety patients of diabetes mellitus and cerebral infarction, having the symptom of deficiency in both vital energy and yin with blood stasis, were divided into three treatment groups at random:ILILI group (A), TCM treatment group (B), and a group with compound treatment of ILILI and TCM (C). The level of blood rheology and endothelin were observed after 1 month’s treatment. Result Compared with group A and group B, group C could significantly reduce the level of fibrinogen and endothelin, improve the deformed ability of RBC. Conclusion ILILI with Tangnaoluotong can significantly alter the blood rheology and endothelin on the patients of diabetes mellitus and cerebral infarction, which result in a better curative effect.

Objective To investigate the effect of controlled low central venous pressure(CLCVP) on blood loss and prognosis in different types of hepatectomy .Methods Two hundred and fifty seven patients underwent standard hepatectomy ,half liver resec‐tion or irregular partial hepatectomy from January 2011 to December 2012 in the First Affiliated Hospital of Chongqing Medical U‐niversity were retrospectively studied .Patients treated with CLCVP during hepatectomy were attributed to the CLCVP group .CVP of these patients were lowed to below 5 cm H2 O by minimizing fluid infusion and one or both of the following maneuvers :posture adjustment ,nitroglycerin administration .Alpha agonists were used when necessary to maintain the mean arterial pressure MAP at ≥60 mm Hg .Other patients been maintained with normal level of CVP by adjusting fluid administration were included in normal CVP group (NCVP) .Blood loss and transfusion volume ,length of hospital stay of the two groups were compared ,and the effects of different surgery type on CLCVP blood protection were evaluated .Results In the patients underwent standard hepatectomy or half liver resection ,intraoperative blood loss and transfusion were not statistically different between the two groups .While in the pa‐tients underwent irregular partial hepatectomy ,the CLCVP group suffered less blood loss and transfusion(P<0 .05) .Percentage of the patients with less than 200 mL blood loss and no transfusion of concentrated red cell in CLCVP group was higher than that of in NCVP group(P<0 .05) .Differences between the two groups in postoperative hospital stay were with no significance in all the operation types(P>0 .05) .Conclusion The efficiency of CLCVP on blood protection during hepatectomy is influenced by the sur‐gery type ,the blood protection is found to be significant only in irregular partial hepatectomy .No relationship was found between CLCVP and postoperative hospital stay in all types of hepatectomy .

Objective To investigate methods for prenatal molecular diagnosis of fetuses at high risk for X-linked adrenoleukodystrophy(X-ALD).Methods The amniotic fluid was obtained and genomic DNA was isolated from amniotic fluid cells.Maternal contamination was evaluated by paternity test.PCRRFLP,sequencing and denaturing high performance liquid chromatography(DHPLC)were used to detect the ABCD1 gene of fetal genome.Results In the pedigree 1,the PCR product(799 bp)of the fetus 1 and her father(normal control)could be digested with BcnI. No P560L mutation,which was present in the index patient,was detected in the ABCD1 gene from the genomic DNA of the fetus 1 using direct sequencing.In the pedigree 2,the PCR product(232 bp)of the fetus 2 and her father could not be digested with MaeI and no Q177X mutation,which was present in the propositus,was detected in the ABCD1 gene from the genomic DNA of the fetus 2 using direct sequencing.In the pedigree 3,the PCR product(271 bp)was digested with AciI.the pattern of the fetus 3 and the propositus being the same,and the R617C mutation was found in the ABCD1 gene from the genomic DNA of the fetus 3 using direct sequencing.In the pedigree 4,the PCR product(269 bp)was analyzed with the DHPLC,and the pattern of elution peaks of the fetus 4 and her father was similar,but different from that of the propositus.No K276E mutation was detectable in the ABCD1 gene from the genomic DNA of the fetus 4 by using direct sequencing.Judging from the sex of the fetuses,fetuses 1 and 2 were normal homozygotes,fetus 3 was an ALD hemizygote,and fetus 4 was a normal hemizygote.Conclusion A new protocol for X-ALD prenatal molecular diagnosis is proposed,which would ensure the accuracy of prenatal diagnosis.

Objective To observe the lung protection of Astragalus membranaceus against radiotherapy to intermediate-stage and terminal thoracic neoplasm, and its influence on TNF-α and ET expression.Methods The patients with intermediate-stage and terminal thoracic neoplasm under radiotherapy were divided into a treatment group and a control group.Patients in the treatment group took 10 ml of Asragalus membranaceus twice a day.for consecutive 6 months from the beginning of radio therapy.TNF-α and ET in the plasma were measured before and after the radiotherapy.The clinical symptom,iconographic changes and lung diffusion were observed from the 15th day of radiotherapy.Results The TNF-α and ET in plasma afterthe radiotherapy were(2.48±0.75)as/ml and(69.32±23.03)pg/ml for the treatment group,and(5.12±1.01)ns/ml and(97.87±37.83)pg/ml for the control group with the statistial difference(x2=7.49,6.57,P<0.001).The decrease of CO diffusion 5 and 10 months after the radiotherapy in the treatment group was statistically different compared with that in the control group(x2=3.98,3.78,P<0.05).There was a statistical difference of the incidence of acute radiation pneumonitis and pulmonary fibrosis between these two groups(P<0.05).Conclusions Astragalus membranaceus could inhibit the excess expression of TNF-α and ET in plasma and reduce the deterioration of diffusion after radiotherapy,so that it can be used for intervention of lung injuries from radiotherapy.

The effect of the complement C1q expression on total hepatic ischemia-reperfusion (I/R) injury in rats was investigated. Sixty healthy male Sprague Dawley (SD) rats weighing 180-200 g were randomly divided into 5 groups: sham-operation group (S group, n=12); group of I/R for 1 h (I/R 1 h group, n=12); group of I/R for 3 h (I/R 3 h group, n=12); group of I/R for 6 h (I/R 6 h group, n=12); group of I/R for 24 h (I/R 24 h group, n=12). The hepatic I/R model of rats was established, and liver tissues were obtained 1 h, 3 h, 6 h and 24 h after hepatic I/R, respectively. Furthermore, the tissues were stained using hematoxylin-eosin, and the liver injuries of rats were observed using a microscope. The malondialdehyde (MDA) level and superoxide dismutase (SOD) activity in liver tissue were determined. Real-time polymerase chain reaction (PCR) and Western blotting were used to detect the expression levels of C1q mRNA and protein, respectively. As compared with the S group, the histopathological changes in I/R 1 h-24 h groups were gradually aggravated with the extension of I/R time. As compared with the S group, SOD activity and MDA content in the I/R groups were reduced and increased respectively with the extension of I/R time (P<0.01). Furthermore, the C1q expression at mRNA and protein levels in the I/R groups (especially in the I/R 3 h group) was significantly higher than that in the S group (P<0.05). It is suggested that C1q expression may play a principal role in hepatic I/R injury, particularly at the early stage of perfusion.
