AIM: Our research attempted to evaluate the overall functional reserve of cirrhotic liver by combination of hepatic functional blood flow, liver volume, and ChildPugh′s classification, and to discuss its value of clinical ***: Ninety two patients with portal hypertension due to hepatic cirrhosis were investigated. All had a historyof haematemesis and hematochezia, esophageal and gastric fundus varices, splenomegaly and hypersplenia.A 2-year follow-up was routinely performed and no one was lost. Twenty two healthy volunteers were used as control group. Blood and urine samples were collected 4times before and after intravenous D-sorbitol *** hepatic clearance (CLH) of D-sorbitol was then calculated according to enzymatic spectrophotometric method while the total blood flow (QToTAL) and intrahepatic shunt (RINs) were detected by multicolor Doppler ultrasound, and the liver volume was measured by spiral CT. Data were estimated by t-test, variance calculation and chi-squared test. The relationships between all these parameters and different groups were investigated according to Child-Pugh classification and postoperative complications ***: steady blood concentration was achieved 120 mins after D-sorbitol intravenous infusion, which was (0.358±0.064) mmoⅠ@L-1 in cirrhotic group and (0.189±0.05)mmol@L-1 in control group (P＜0.01). CLH=(812.7±112.4) ml@min-1,QTOTAL=(1280.6±131.4) ml@min-1, and RINs=(36.54±10.65)%in cirrhotic group and CLH=(1248.3±210.5) ***-1, QTOTAL=(1362.4-±126.9) ml@min-1, and RINs=(8.37±3.32) % in control group (P＜0.01). The liver volume of cirrhotic group was 1057±249 cm3, 851±148 cm3 and 663±77 cm3 in Child A, B and C group respectively with significant difference (P＜0.001).The average volume of cirrhotic liver in Child B, C group was significantly reduced in comparison with that in control group (P＜0.001). The patient, whose liver volume decreased by 40 % with the CLH below 600 ml@min-1, would have a higher

The middle segment of the northern margin of the North China Craton （NCC） consists mainly of metamorphosed Archean Dantazi Complex, Paleoproterozoic Hongqiyingzi Complex and unmetamorphosed gabbro-anorthosite-meta-alkaline granite, as well as metamorphosed Late Paleozoic mafic to granitoid rocks in the Damiao-Changshaoying area. The -2.49 Ga Dantazi Complex comprises dioritic-trondhjemitic-granodoritic-monzogranitic gneisses metamorphosed in amphibolite to granulite facies. Petrochemical characteristics reveal that most of the rocks belong to a medium- to high-potassium calc-alkaline series, and display Mg^# less than 40, right-declined REE patterns with no to obviously positive Eu anomalies, evidently negative Th, Nb, Ta and Ti anomalies in primitive mantlenormalized spider diagrams, εnd（t）=＋0.65 to -0.03, and depleted mantle model ages TDM=2.78-2.71 Ga. study in petrogenesis indicates that the rocks were formed from magmatic mixing between mafic magma from the depleted mantle and granitoid magma from partial melting of recycled crustal mafic rocks in a continental margin setting. The 2.44-2.41 Ga Hongqiyingzi Complex is dominated by metamorphic mafic-granodioritic-monzogranitic gneisses, displaying similar petrochemical features to the Dantazi Complex, namely medium to high potassium calc-alkaline series, and the mafic rocks show evident change in LILEs, negative Th, Nb, Ta, Zr anomalies and positive P anomalies. And the other granitiod samples also exhibit negative Th, Nb, Ta, P and Ti anomalies. All rocks in the Hongqiyingzi Complex show right-declined REE patterns without Eu anomaly. The metamorphic mafic rocks with εnd（t） = -1.64 may not be an identical magmatic evolution series with granitoids that have εnd（t） values of ＋3.19 to ＋1.94 and TDM ages of 2.55-2.52 Ga. These granitic rocks originated from hybrid between mafic magma from the depleted mantle and magma from partial melting of juvenile crustal mafic rocks in an island arc setting. All the -311 Ma Late

Introduction Granulomatous hypophysitis(GRH) is extremely rare and commonly presents with chronic inflammatory of the enlarged pituitary gland initially described in 1917 and the first mortem case was reported in *** presentation sixty-six-year-old and 57-year-old women,both Chinese,were diagnosed with GRH presenting preoperatively definite imageology characters as pituitary *** 66-year-old woman presented with half a year of headache,a gradual decrease of visual acuity and 1 month of right ptosis. serum prolactin level was slightly *** Computed Tomography(CT) scanning revealed typical low density mass found on the enlarged sella,which demonstrated invasive extending from the sella to the right cavernous sinus by contrast enhanced ***,the patient was diagnosed with probable invasive pituitary *** other 57-year-old woman complained a light headache and had been previously treated as nonfunctional pituitary adenoma in other *** these two patients underwent transsphenoidal microsurgery and were diagnosed with granulomatous hypophysitis according to postoperative histopathology. They then were treated with *** the follow-up,the clinical symptoms such as headache,visual damage and ptosis vanished,and the mass of the sellae dramatically shrank on repeated MR *** Clinically and radiologically,GRH is a rare sella entity easily to be misdiagnosed as a pituitary *** surgery can decompress the optical nerve or oculomotornerve as a therapeutic strategy,and support biopsy or further pathological ***,the hormonal therapy should be emphasized both as diagnostic and therapeutic *** and tentative steroid treatment should be performed in preoperative period without acute nerve damage.

The effect of trace addition of 0.2 wt.%Zn on the microstructures and mechanical properties of the age-hardening Mg-4.2y-2.5nd-1Gd-0.6Zr(wt.%)(WE43)alloy has been *** compared with the WE43 alloy after solid solution treatment at 525 ℃,the block-like Zn-Zr phase was still observed in the WE43-0.2Zn ***,the time for WE43-0.2Zn alloy to get peak hardness at 250 ℃ was two hours,a half earlier than that in WE43 alloy,meaning a accelerated age precipitation kinetics has been achieved due to the addition of 0.2 wt.%*** with 0.2 wt.%Zn enhanced the ultimate tensile strength(UTs)slightly and ductility significantly both in the solutionized and peak aged *** enhancement in strength and ductility is possible associated with the larger volume fraction of precipitation phases due to a reduction of the solubility of rare earth elements(RE)in theα-Mg matrix,the larger aspect ratio(length to width)of precipitates and a decrease in stacking fault energy by addition of Zn.

目的　探讨矽肺与血液流变学的关系及其临床意义。方法　检测了８５例男性矽肺患者、４５例男性慢性支气管炎患者及１００例健康男性对照者的血液流变学各项指标值。结果　与对照组和慢性支气管炎组比较，矽肺组的红细胞压积、切变率为４ｓ－１～２００ｓ－１时的全血表观黏度、血浆黏度、红细胞电泳时间、血小板电泳时间平均值均显著升高；不同病情矽肺组、不同肺功能状况矽肺组上述检测值的平均值均随病情加重、肺功能下降而升高，并均显著高于对照组。逐步回归发现，矽肺患者病情与红细胞压积、４ｓ－１和２００ｓ－１切变率时的全血表观黏度、红细胞电泳时间和血小板电泳时间相关最密切，而肺功能状况和病程却均与红细胞压积、４ｓ－１和２００ｓ－１切变率时的全血表观黏度、血浆黏度、红细胞电泳时间和血小板电泳时间相关最密切。结论　矽肺患者的血液呈高黏滞状况，极易并发多种疾病。
