3.Present statues and progresses of interventional therapy of hepatocellular carcinoma in caudate lobe
Chinese Journal of Interventional Imaging and Therapy 2017;14(8):513-516
Recently,with the recognition of blood supply and anatomy of the liver caudate lobe,the intervention therapies of hepatocellular carcinoma in caudate lobe were enriched.However,because of the complex anatomy,the treatment of hepatocellular carcinoma in caudate lobe is still controversial.The interventional methods for hepatocellular carcinoma in caudate lobe were mainly included transcatheter arterial chemoembolization (TACE),percutaneous ethanol injection (PEI),transcatheter arterial embolization (TAE),radioembolization,radiofrequency ablation (RFA) and endoscopic ultrasound-guided ethanol injection.The present statues and progresses of interventional therapy of hepatocellular carcinoma in caudate lobe were reviewed in this article.
5.Clinical application characteristics of distraction osteogenesis implants
Chinese Journal of Tissue Engineering Research 2009;13(39):7755-7758
OBJECTIVE: To investigate the progress of clinical application of implant during distraction osteogenesis in the jaw bones, and to evaluate its biocompatibility.METHODS: The first author retrieved CNKI database from 1989 to 2009 in Chinese and Medline database from 1989 to 2009 in English with the key words of "jaw, distraction osteogenesis, treatment". A total of 56 articles were screened according to inclusion and exclusion criteria. Finally, 20 articles concerning treatment progress of distraction osteogenesis and clinical application of implant were included.RESULTS: Distraction osteogenesis implants contained intraoral or extraoral distraction device, which could be used for distraction of transport plate. A distraction was selected in accordance with patients' condition and requirement. Distraction osteogenesis had been an important manner for complicated tooth jaw facial deformity and jaw defect in oral dentofacial surgery and Orthodontic treatment. It could have effective osteogenesis in combination with various systemic therapy, local therapy and physical therapy. Presently, distraction osteogenesis implants were metal materials. Metal implants have great advantages in preventing bacterium growth, keeping implant fixation and distraction effects, and the price was high. However, the cost of Ni-Ti memory alloy wire was lower compared with common retractors. The fixing device and alloy wire closely adhered to the bone could be completely implanted into tissues, with the advantages of anti-infection and completely closing the exterior and interior wound. CONCLUSION: Distraction osteogenesis is a new method for treating dental and craniofacial hypodevelopment straightening of teeth and for repairing jaw bone defect deformation. Biocompatibility of metal implants was good such as internal small Ni-Ti memory alloy wire. The biocompatibility of other types of implants should be improved.
6.Study of event-related potential P3-like following forebrain ischemia/reperfusion in rats
Chinese Journal of Pathophysiology 1989;0(05):-
AIM: To clarify the role and mechanism of hippocampus in the formation of P3-like. METHODS: (1) The hippocampal and parietal P3-like were simultaneously recorded by chronically implanted electrodes in rats. (2) In forebrain ischemia/reperfusion model, the effects of the selective damage of hippocampal CA1 subfield on the hippocampal and parietal P3-like were examined. (3) The changes of hippocampal and parietal P3-like after the inhibition of acetylcholine activity in the septo-hippocampal pathway by intraperitoneal injection of atropine (30 mg/kg) were also detected. (4) The changes of conditional active avoidance response was tested by shuttle-box following forebrain ischemia/reperfusion. RESULTS: (1) The peak latencies of hippocampal and parietal P3-like were prolonged after forebrain ischemia/reperfusion. (2) The polarity of hippocampal P3-like were reversed after the inhibition of acetylcholine activity in the septo-hippocampal pathway by atropine. (3) The prolongation of P3-like peak latency was closely related to the lowering of the score of conditional active avoidance response after forebrain ischemia/reperfusion. CONCLUSION: (1) The formation of P3-like depends on the integrity of hippocampus formation. (2) Hippocampus is not the only generator of P3-like, P3-like could be produced in multiple way. (3) The activity of acetylcholine in the septo-hippocampal pathway has notable effects on the formation of P3-like. (4) P3-like could be used as the sensitive marker of cognitive function.

8.The clinical application of mirabilite abdominal hot compression bag for treating acute pancreatitis
Chinese Journal of Pancreatology 2016;16(5):320-325
Objective To explore the clinical application of mirabilite abdominal hot compression bag designed by ourselves for the moderately severe acute pancreatitis ( MSAP ) or severe acute pancreatitis ( SAP) .Methods Seventy MSAP and SAP patients were randomly divided into the observed and control groups according to the admission date.Each group included 35 patients.All the patients received the routine treatment.The patients in observed group received the treatment of compression action on abdomen by mirabilite abdominal continual hot compression bag designed by ourselves, while the traditional mirabilite hot compression action was used in the control group.The APACHEⅡscore and the levels of plasma CRP, IL-1, IL-6 and TNF-αof all patients on the 1st, 3rd, 6th, and 9th day after being admitted, the rate of complications including the intra-abdominal hypertension (IAH), pancreatic pseudocysts (PPC) and pulmonary infection, the recovery time of intestinal function and mean hospitalization time were all recorded and the therapeutic efficacy was compared between the two groups.Furthermore, the therapeutic effects of MSAP and SAP were compared between two groups.Results The APACHEⅡscore and the levels of plasma CRP, IL-1, IL-6 and TNF-αwere not statistically different between the two groups on the 1st day after hospitalization.The APACHEⅡscore and the levels of plasma CRP, IL-1 and TNF-αon the 3rd day in the observed group were significantly lower than those in the control group(P<0.05 or <0.01).The APACHEⅡ score and the levels of plasma CRP, IL-1 , IL-6 and TNF-αon the 6th day in the observed group were significantly lower, comparing to those in the control group.The levels of serum IL-1 and TNF-αin the observed groups were significantly lower than those in control group on the 9th day.All the differences above were statistically significant ( P<0.05 or <0.01).In the observed group, 4 cases (11.4%) had IAH and 7 cases (20.0%) developed other complications.The time of intestinal recovery and mean hospitalization was (4.9 ±0.8)d and (13.1 ±2.1)d, respectively, in the observed group.In the control group, 11 cases (31.4%) had IAH and 10 cases (28.6%) had other complications, and the time of intestinal recovery and mean hospitalization was (5.5 ±0.8) d and (15.4 ±3.9)d,respectively,.The rate of IAH, intestinal function recovery time and hospitalization time in the observed group were significantly less than those in control group (P<0.05 or <0.01).There was no statistical difference on other complications between the two groups.The intestinal function recovery time and hospitalization time of MSAPs in the observed group were significantly less than those in control group [(5.0 ± 0.8)d vs (5.5 ±0.8)d, P=0.03; (12.7 ±1.7)d vs (15.2 ±3.6)d, P=0.02].The APACHEⅡ score and the levels of plasma CRP, IL-1, IL-6 and TNF-αof SAPs were not statistically different between the two groups.Conclusions The application of the mirabilite abdominal continual hot compression bag could alleviate inflammatory response of MSAP and SAP, decrease the rate of IAH, improve the intestinal function recovery time,and shorten the hospitalization time.
