Aquaporin-4 (AQP4) is an important structural basis for water regulation and trans- portation in the central nervous system,which participates in physiopathological processes, such as cerebrospinal fluid reabsorption, osmotic regulation, and cerebral edema formation. Protein kinase C (PKC) exists in various cells, it catalyzes the phosphorylation of serine or threonine residues on various protein substrates.In recent years, studies have found that there is a certain correlation between the expressions of AQP4 and PKC after ischemic stroke.This article re- views the distribution,function,functional regulation of AQP4 and PKC,and their relations in ischemia-reperfusion.

Objective To investigate the clinical and magnetic resonance imaging (MRI) manifestations of acute disseminated encephalomyelitis (ADEM).Methods The clinical, neuroimaging and neuropathological data of a patient with ADEM were analyzed retrospectively.Results The clinical features of the patient included acute onset,paroxysmal dizziness, nausea and vomiting. Cerebral MRI showed multiple, asymmetrical, long T1 and long T2 signals, which appeared periventricular areas and white matter regions of frontal, parietal, occipital and temporal lobe. Pathologic examination showed brain tissue denaturalization with chronic inflammation and massive inflammatory lymphocyte infiltrations in perivascular spaces. Treatments such as surgery operation, dehydration and anti-infection were invalid, while glucocorticosteroid had stable therapeutic efficacy.Conclusions When a patient presents with dizziness, nausea and vomiting, and multifocal lesions appear in the white matter of brain in MRI, the diagnosis of ADEM must be taken into concern. Curative effect of glucocorticosteroid for this disease is confirmed.

Objective To analysis effect of ShenQi FuZheng injection on peripheral blood angiotensin II(AngⅡ), endothelin-1(ET-1) levels and clinical curative effect in patients with congestive heart failure.Methods 52 patients who were diagnosed with chronic heart failure were collected.All patients were randomly divided into experimental group and control group, 26 cases in each group.Patients in the control group received conventional western medicine treatment, patients in the experimental group were given ShenQi FuZheng injection on the basis of control group treatment, after the treatment, the plasma levels of AngⅡ and ET-1, cardiac function and clinical efficacy were detected in all patients.Results After treatment, compared with control group, the plasma levels of AngⅡ was lower in the experimental group(P<0.05);the plasma levels of ET-1 was lower in the experimental group(P<0.05); the LVEF,CO and SV levels were higher,and the LVED level was lower in the experimental group(P<0.05); the effective rate of patients in the experimental group was higher(P<0.05).Conclusion The ShenQi FuZheng injection can significantly reduce the plasma AngⅡand ET-1 levels in patients with congestive heart failure, improve heart function and clinical curative effect.

Objective To evaluate the role of P2X3 receptors in the development and mnaintenance of neuropathic pain (NP) and the relationship with nuclear factor kappa B (NF-κB) in dorsal root ganglia of rats.Methods Thirty-six SPF healthy male Sprague-Dawley rats,weighing 180-200 g,aged 4-6 weeks,in which intrathecal catheters were successfully implanted,were divided into 3 groups (n =12 each) using a random number table:sham operation group (group S),NP group and P2X3 receptor antagonist A-317491 group (group A).At 3 days after intrathecal catheters were successfully implanted,NP was induced by chronic constriction injury to the sciatic nerve.The sciatic nerve was only exposed but not occluded in group S.Intrathecal injection was performed twice a day for 14 consecutive days starting from 1 day after operation.Normal saline 20 μ l was intrathecally injected in group S and group NP,and A-317491 100 nmol/10 μ1 and normal saline 10 μ l were intrathecally injected in group A.Thermal paw withdrawal threshold (TWT) and mechanical paw withdrawal threshold (MWT) were measured on day 1 before operation and at 30 min after intrathecal injection on days 1,3,7,10 and 14 after operation.On days 7 and 14 after operation,the rats were sacrificed and the dorsal root ganglia of the lumbar segment were removed for determination of the expression of P2X3 receptors and NF-κB p65 by Western blot.Results Compared with group S,TWT and MWT were significantly decreased at each time point after operation,and thc expression of P2X3 receptors andi NF-κB p65 in dorsal root ganglia was up-regulated on days 7 and [4 after operation in group NP (P＜0.05 or 0.01).Compared with group NP,TWT was significantly increased at each time point after operation,MWT was increased on days 3,7,10 and 14 after operation,anl the expression of P2X3 receptors and NF-κB p65 in dorsal root ganglia was down-regulated on days 7 and 14 after operation in group A (P＜0.05).Conclusion The mechanism underlying the development and maintenance of NP is related to the up-regulation of P2X3 receptor expression and promotion of the expression of NF-κB in dorsal root ganglia of rats.

Objective To evaluate the role of transient receptor potential channel 8 (TRPM8) in the development and maintenance of neuropathic pain and the relationship with nuclear factor kappa B (NF-κB) in the dorsal root ganglion of rats.Methods Thirty-six pathogen-free healthy adult male SpragueDawley rats,weighing 180-200 g,aged 6-8 weeks,were divided into 3 groups (n=12 each) using a random number table:sham opeation group (group S),neuropathic pain group (group NP) and TRPM8 bocker BCTC group (group BCTC).Neuropathic pain was induced by ligation of the right sciatic nerve in anesthetized rats.BCTC 20 nmol was intrathecally injected once a day on preoperative day 1 and postoperative days 1,3,7 and 10 in group BCTC.The thermal,mechanical and cold pain thresholds were measured on preoperative day 1 and postoperative days 1,3,7,10 and 14.The dorsal root ganglions of the lumbar segment (L4-6) were removed on postoperative days 7 and 14 for determination of the expression of TRPM8 and NF-κB p65 by Western blot.Results Compared with group S,the thermal and mechanical thresholds were significantly decreased on postoperative days 1-14,and the cold pain threshold was decreased on postoperative days 3-14 in NP and BCTC groups,the expression of TRPM8 and NF-κB p65 in dorsal root ganglions was up-regulated on postoperative days 7 and 14 in group NP (P＜0.05),and no significant change was found in the expression of TRPM8 and NF-κB p65 in dorsal root ganglions in group BCTC (P＞0.05).Compared with group NP,the thermal pain threshold was significantly decreased and the cold pain threshold was increased on postoperative days 3-14,the expression of TRPM8 and NF-κB p65 in dorsal root ganglions was up-regulated on postoperative days 7 and 14,and no significant change was found in the mechanical pain threshold in group BCTC (P＞0.05).Conclusion NF-κB activation after opening of TR-PM8 in dorsal root ganglion neurons is involved in the development and maintenance of neuropathie pain in rats.

Objective To classify the segmental bronchial patterns of the left upper lobe by combining three post-processing images from 64 slice spiral CT and to study how to identify different ramifications in transverse thin-section CT.Methods Totally 204 patients with routine thorax scans were enrolled.The segmental bronchi were demonstrated in terms of bronchial tree,virtual bronchoscopy and thin-section CT three post-processing images.Integrated with the three post-processing images,the segmental bronchial patterns of the left upper lobar bronchi were classified into several main types,and displayed in transverse thin-section CT.Results The segmental bronchial ramifications of the left upper lobe were classified into three types mainly:common stem of apical and posterior segmental bronchi(64%,130/200),trifurcation(23%,45/200),common stem of apical and anterior segmental bronchi(10%,21/200),and they could be identified in two typical slices of transverse thin-section CT.There were two dominating types in the left basilar segmental bronchi:bifurcation(75%,163/216),trifurcation(18%,39/216),and they could also be identified in two typical slices of transverse thin-section CT.Conclusion The segmental bronchi of the left lung can be definitely classified by three post-processing images from 64 slice spiral CT.

Objective To classify the segmental bronchial patterns of the right upper lobe by combining bronchial tree and CT virtual bronchoscopy(CTVE)post-processing techniques from 64-slice spiral CT.Methods Two hundred and four patients with routine thorax scans were enrolled.The segmental bronchi were demonstrated in terms of bronchial tree and CTVE.First,we checked how many patients can be classified with any one of the above post-processing approaches.Then,integrating the two methods,we classified the fight upper segmental bronchial patterns of the 204 patients.At last,the patterns of the right upper bronchus were analyzed.Results bronchial tree post-processing images were stereoscopic and intuitive.It could be used to identify common stem of bifurcation easily,however,it was hard to be used to differentiate short common stem of bifurcation from trifurcation.CTVE demonstrated segmental bronchi from inside of lumen,and can readily show the short common stem of bifurcation and trifurcation of bronchi.Combining two post-processing techniques,the segmental bronchial ramification of the right upper lobe was mainly classified in three types:trifurcation in 76 patients(37.3%),common stem of apical and posterior segmental bronchi in 50 patients(24.5%)and others in 78 patients(38.2%).Conclusion The combination of multiple post-processing of 64-slice CT posses great superiority to classify the pattern of the right upper lobe bronchi.
