Clinical data of 40 cases of advanced schistosomiasis complicated with liver cancer were analyzed in this paper.

Arteriovenous fistula (AVF) and arteriovenous malformation (AVM) are the common intracranial vascular malformations. The experimental models of AVF and AVM include animal models, in vitro models and biomathematical models. These models could be used to investigate the pathophysiological characters of AVF and AVM, to simulate the clinical treatment, and to examine the materials for embolization therapy. This article reviewed the formation of these models, evaluated their advantages and disadvantages, and briefly introduced their applications.

This article points out that the key of studying classics of Chinese medicine and Yijing is to precisely comprehend cultural information in these books. There are 3 key points about prehension and interpretation. The first one is correct identification and differentiation of specific cultural connotation as basic carrier of ancient cultural information,such as language,characters,symbols and figures. The second one is comprehensive understanding of the complex relationship among infiltrated cultural information of encyclopedia. The third one is accurate master of cultural information during the process of academic development.

Objective To observe the effect of laser of Q Switch Nd:YAG 1 064nm wave length laser in the treatment of naevus fusco caerulens zygomaticus. Methods Since October 2000, forty nine cases of naevus fusco caerulens zygomaticus had been treated once every three months. Results Thirty two cases had been treated three times, and seventeen cases, four times. The total effective rate was 100 %. The pigmentation of all the cases were darker after the first treatment, later as the treatment progressed, the pigment became lighter. No pigment loss was seen. Conclusion Q switch Nd:YAG 1 064 nm wavelength laser has a good effect in the treatment of naevus fusco caerulens zygomaticus. It is safe and reliable.

Objective Vascular mild cognitive impairment(VaMCI) refers to mild cognitive impairment caused by or associated with vascular causes.This study aims to investigate the characteristics of the cognitive impairment in patients with vascular mild cognitive impairment (VaMCI).Methods Seventy-five patients with VaMCI(VaMCI group) and 38 healthy old subjects whose age, sex and education level match the VaMCI group patients(control group) were recruited from the department of Neurology, Beijing Chaoyang Hospital, Capital Medical University between Jan 2016 and June 2016.The neuropsychological examinations were used to evaluate the severity of cognitive impairment, specifically including the Minimum Mental State Examination(MMSE), Montreal cognitive assessment scale(MoCA), Clinical Dementia Rating(CDR), Activity of Daily Living Scale(ADL), Hachinski ischemic score table, Hamilton Depression Scale(HAMD) and Auditory Verbal Learning Test(AVLT).The Fazekas scale was used to assess the severity of white matter lesions, and the medial temporal lobe atrophy rating scale(MTA) was used to evaluate the atrophic severity of medial temporal lobe.Results The overall cognitive function score in VaMCI group was significantly lower than the control group [MMSE [25.7±2.3 vs 28.4±2.0] MoCA [22.8±3.9 vs 26.3±3.7]], the differences was statistically significant(P<0.05);as well as the AVLT-I [5.1±1.0 vs 8.9±1.9], AVLT-D [3.7±1.0 vs 9.8±1.5] and AVLT-R [7.6±1.9 vs 12±1.5] scores in VaMCI group was significantly lower than the control group, the differences was statistically significant(P<0.05), which suggested patients with VaMCI have overall cognitive impairment, especially memory impairment.But Fazekas and MTA scores in VaMCI groups were higher than the control group, the differences was statistically significant(P<0.05).Correlation analysis showed that the scale of medial temporal lobe atrophy had a negative relationship with the performance of MoCA (r=-0.434,P=0.002).Conclusion Our findings demonstrate patients with VaMCI have significant cognitive impairment, especially memory impairment, which may be correlated to the severity of the white matter lesions and the medial temporal lobe atrophy.

Objective To investigate the effects of controlled hypotension induced with sodium nitroprusside (SNP) or nicardipine on hemodynamics during hip operation and postoperative hepatic and renal function.Methods Twenty ASA Ⅰ or Ⅱ patients aged 20-70 yrs weighing 50-80 kg scheduled for total hip replacement or open reduction and internal fixation of fracture of acetabulum were randomized to receive either SNP (group Ⅰ ) or nicardipine (group Ⅱ ) for induced hypotension during operation. Each group included 10 patients. Radial artery and right internal jugular vein were cannulated for BP and CVP monitoring. The probe of Hemo-Sonic ?100 esophageal supersonic hemodynamic monitor (Arrow U.S.A) was placed in the esophagus and fixed when best signal was obtained. ECG, hemodynamics including MAP, HR, CVP, CO and other parameters, SpO2 and PetCO2 were continuously monitored. Anesthesia was induced with propofol 2 mg?kg-1 , fentanyl 2-3 ?g? kg-1 and vecuronium 0.1 mg?kg-1 and maintained with 1.5% isoflurane and continuous infusion of propofol ( at 4-6 mg?kg-1 ?h-1 ) and intermittent i.v. boluses of vecuronium after tracheal intubation. MAP was reduced to 55-65 mm Hg with SNP (at a rate of 0.5-8.0 ?g?kg-1?min-1 ) or nicardipine (at 1.0-8.0 ?g?kg-1 ?min-1 ) . Intraoperative blood loss and blood transfusion and postoperative drainage from the wound were measured and recorded.Hemodynamic parameters were recorded before hypotension and 15, 30 and 60 min after start of induced hypotension and 15 and 30 min after recovery from hypotension. Hepatic and renal functions were measured before and after operation using total bilirubin, AST, ALT, BUN and creatinine. Results The two groups were comparable with respect to sex ratio (M/F) , age, height, body weight, duration of induced hypotension and operation. MAP and systemic vascular resistance (SVR) were significantly reduced and tachycardia developed during hypotension in both groups. The left ventricular ejection time was significantly prolonged and aortic blood flow (ABF) and cardiac output (CO) were significantly increased and CVP was lowered during hypotension as compared to the baseline values in SNP group. BUN was significantly reduced after operation ( P
