Purpose Progressive hypertensive intracerebral hemorrhage (PHICH) is often observed in clinical ward,but its prognosis is undetermined.This study is to investigate the duration and the risk factors of progressive hypertensive intracerebral hemorrhage.Methods The diagnosis of PHICH was determined by comparing the first and second CT scans.Potential risk factors including the sex,age,location of hematoma,blood pressure,coagulopathy and the duration of admission to the first CT scan were analyzed.Results In a cohort 143 patients,the PHICH were found in 41 cases(28.7%)after the second scan,and among them,32 patients(22.4%)were necessary to perform craniotomy for evacuation of hematoma,most of the PHICH occurred within 24 hours after onset.Older age,thalamus bleeding,high systolic blood pressure within 6 hours,coagulapathy and shorter duration from admission to the first CT scan were the predictors associated with PHICH.Conclusion PHICH occurs in almost 1/4 of hypertensive intracerebral hemorrhage,predominantly in elder,thalamus bleeding,coagulapathy,high systolic blood pressure within 6 hours and shorter duration between onset and the first CT scan.CT examination within 24 hours after admission is crucial to reveal the exact condition of the patient.

Objective Through pathological and histological examination on retina to research the dosage relevance of trace PFD with toxicity in rabbit retina,and provide experimental reference basis for clinical practice.Methods Fourty eight eyes from 24 experimental rabbits were randomly divided into experimental group(36 eyes) and control group(12 eyes).The experimental one was divided into 3 groups,12 eyes in each group.The surface of rabbit retina was directly injected with 30,50,and 100 ?L liquids of PFD and BSS.The conditions of rabbit retina were observed under ophthalmoscope every day after the liquid injection.The sections of retina tissue were observed under transmission electron microscope in each experimental and control groups at the 4th,7th,14th and 21th day after injection.Results All samples were normal by ophthalmoscope examination while no pathological change of retina was found at various time points .At the 4th day,none substantial damage had been made in any dosage groups by transmission electron microscope examination except for 100 ?L group.Only one retina of 100 ?L group showed that the space around cell nucleus broadened appreciably,slightly atactic nucleus and slightly compact cytoplasm.It showed some early changes.From the 7th day,similar pathological changes were found: damage on outer segments of light receptor and outer plexiform layer,properties changes of light receptor,forming of vesicles of inner nuclear cells,damage of ganglion cell,dying of inside retina,actions of gulping cells in retina,swallow of film plates by pigment epithelial cell of retina,and dropping of top fine hair. But the retina of control group had no pathological changes.Conclusion Trace PFD exists in eyes.There is no relevance between poisonous development of retina and remaining dosage of PFD.However,large remaining of PFD can lead to retina toxicity early.

Objective To explore the influence of fluoxertin on level of IL-2 ,IL-6 and TNF-α in brain tissue and serum of rats with post-stroke depression(PSD) .Methods 60 rats were divided into sham operation group ,depression group ,stroke group ,PSD group and fluoxertin group ,12 cases in each group .ELISA was used to detect the level of IL-2 ,IL-6 and TNF-αin brain tissue and serum .Results The level of IL-2 ,IL-6 and TNF-αin depression group ,stroke group and PSD group were significantly increased and higher than that in sham operation group and fluoxertin group(P<0 .05) .There was no significant difference between sham op-eration group and fluoxertin group(P>0 .05) .Conclusion Fluoxertin could significantly decrease the level of IL-2 ,IL-6 and TNF-αand play an important role in therapy of PSD .

Objective:To study the indicators and operative method of retroperitoneal laparoscopic nephropexy.Methods: From August2001to June2003,8patients with nephroptosis underwent retroperitoneal laparospic nephropexy.All cases were women with an average age of34years(range26-45years).Five cases involved the right kidney,2on the left and1on the both.The presurgical symptoms included constant and recurring pain in8cases,upper urinary infections in6,hematuria in 5,upper tract obstruction in4.A retroperitoneoscopic procedure was performed after positioning the patient in the flank posi-tion.The decisive part was complete exposure exposure within Gerota'fascia to mobilize potential adhesions or the colon,espe-cially to pull inferior blood vessel of the kidney.Nephropexy was performed between the fibrous capsule of the lower pole of the kidney and the dissected psosa muscle using3sutures placed by intracorporeal or extracorporeal technique.Results:The mean operative time was125min(range115-240min);the mean post-operative hospital stay was9d,and the mean bedrest time was7d.During a mean follow-up of12months(range3-20months),1patient complained of recurrent pain,and there was1hematuria.No patient had further episodes of pyelonephritis or upper tract obstruction.IVP revealed kidneys in the af-fected part were in the normal region and greatly improved.Conclusion:Retroperitoneal laparoscopic nephropexy has less trauma,less post-operative discomfort and quicker recovery.It should be considered as the first choice for nephroptosis.[

Objective To investigate the changes of serum angiopoietin-like protein 3 (Angptl3) and adiponectin levels in patients with metabolic syndrome (MS) in order to understand their association with the MS. Methods Serum Angptl3 and adiponectin levels were measured by sandwich ELISA in a group of 111 patients with MS and 152 normal controls. Results Serum adiponectin was lower in the MS patients than in the control subjects [4.22(1.01-23.29) μg/mL vs. 5.41(0.97-22.27) μg/mL, P<0.05]. With regard to serum Angptl3, there was no significant difference between the 2 groups(P>0.05). Serum adiponectin was correlated to Angptl3 and high density lipoprotein-cholesterol (HDL-C)(P<0.001) and negatively correlated to body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), triglyceride (TG), fasting plasma glucose (FBG), fasting insulin (FINS) and homeostatic model assessment method-insulin resistance (HOMA-IR) (P<0.001). Serum Angptl3 was positively correlated with adiponectin (P<0.001). Serum adiponectin was found to be independently positive determinant for Angptl3 concentrations (b′=0.256, P<0.001). Adiponectin was inversely correlated with TG and HOMA-IR (b′=-0.234, -0.145, P<0.001). Conclusion Adiponectin is decreased in MS patients and may be correlated to Angptl3.

Objective To clarify the quorum sensing and identify the quorum sensing molecular of Cryptococcus neoformans. Methods The growth of Cryptococcus neoformans TUP1 △ strain at different inoculum size was observed. The culture filtrate of high cell density TUP1△ strain was collected and plated on medium with low density TUP1△ cell, and the growth of low cell density TUP1△ was recorded. Finally, the active molecule in culture filtrate was purified and identified.Results The growth of Cryptococcus neoformans TUP1△ strain was density dependent and the colony could be normally formed only above a specific density. The filtrate from a high cell density TUP1△culture could promote the growth of low cell density TUP1△, and the active molecule in this culture filtrate was identified to be an oligopeptide composed of 11 amino acids pepride, named quorum sensing peptide 1(QSP1). QSP1 was artificially synthesized, which could also promote the colony forming of TUP1△ strain inoculated at low cell density. Conclusion Quorum sensing exists in Cryptococcus neoformans, and the quorum sensing molecular is QSP1.
