12 trace elements from the hairs of 20 cases of aplastic anemia were examined and compared with that from hairs of normal people as control. Results showed that in Yin-deficient type patients, Li, Ca, Si, Cr markedly decreased; in Yangdeficient type patients, Zn, Mg, Ba, Si, Ca, Li markedly decreased, while all 12 trace elements decreased in patients of deficiencies of both Yin and Yang. New approaches were also offered for treatment of aplastic anemia on the basis of differential diagnosis.

Objective: To investigate the distribution features of somatosensory cortical evoked potential map with augmented blocking of the sensation transmission along meridians.Method: The EEG-4400 electro-encephalogram (EEG) and ND-1 brain electrical activity mapping were adopted on 11 volunteers with remarkable sensation transmission along meridians, showing that the sensation can transmit to head and face after stimulating the points below the knee joints. Also, special observation was made on accurate location of somatosensory cortical evoked potential map in 10 people without sensation transmission.Result: Observation on 11 volunteers with remarkable transmission along the Three Foot-yang Meridians showed that they presented with concurrent high potential reactions in somatosensory cortical lower limbs and face without blocking the augmented sensation transmission along the meridians; however, when mechanical pressure was exerted to block the sensation transmission,only one reaction in the lower limbs occurred in the somatosensory cortical evoked map and the other one in the face disappeared. Conclusion: Peripheral tissue evoking is the decisive factor for transmission along the meridians.

This study was aimed to determine effect of Bu-Shen Kang-Shuai (BSKS) Tablet on HO-1 mRNA and its associated oxidative stress levels among atherosclerotic rabbits. A total of 56 rabbits were randomly divided into the normal group (8 rabbits) and the experimental group (48 rabbits). Normal diet was given to the normal group. Atherosclerotic rabbits models were established in the experimental group. At the eighth week, rabblits in the experi-mental group were randomly divided into the model group, BSKS Tablet group and simvastatin group. Blood samples were collected before medication, 8-, 12-, 16-week after medication from rabbits of each group. Rabbits were sacri-ficed under aseptic conditions at the last blood collection. Expressions of aortic HO-1 mRNA and PPARα mRNA were measured by Q-PCR method. The level of MMP-9 was measured by immunohistochemical assay. Serum HbCO, COX-2 activity and cGMP level were measured by ELISA assay. The results showed that after the intervention of BSKS Tablet, serum HbCO level decreasd, cGMP was obviously increased. However, there was no obvious change on the COX-2 activity. The immunohistochemical assay showed that BSKS Tablet obviously reduced MMP-9 level of rabbits. There was only small amount of aortic HO-1 mRNA expression in the normal group. However, the expres-sion of aortic HO-1 mRNA in the atherosclerosis group was increased. After intervention of BSKS Tablet, the ex-pression of HO-1 mRNA was increased with statistical significance (P < 0.05). Simvastatin had similar antioxidant effect. It was concluded that the compound preparation of traditional Chinese medicine (TCM) BSKS Tablets had an important antioxidant effect in treatment of atherosclerosis. Its protective mechanism may be through the regulation of HO-1 mRNA gene expression and effects of HO-1/CO-cGMP pathway activities of related enzymes while peroxida-tion stability of atherosclerotic plaque.

Objective To discuss the feasibility of biodegradable covered magnesium alloys stent for a rabbit model of lateral aneurysm in the common carotid artery (CCA). Methods The left CCA was ligated in 20 conventional New Zealand rabbits. MRA of the neck was performed 1 month after ligation. The rabbits with thickening of the right CCA and non-or slight thickening of the bilateral vertebral arteries were selected for lateral aneurysm model making. The venous pouch and the right CCA wall by discontinuous extroversion sutures, to form a lateral aneurysm model. The biodegradable covered magnesium alloys stents or Willis covered stents were inserted two weeks after model making. Angiography was performed prior to the procedure, 3, 6 and 12 months after stent implantation to evaluate the disappearance of the aneurysms and patency of the right CCA. The degradation behaviour is invastagated with molybdenum target 2 weeks, 1, 2, 4, 6,9 and 12 months after stent placement. Results The left CCAs were successful ligated in all rabbits. MRA 1 month after ligation showed thickening of the right CCA and non-thickening of the bilateral vertebral arteries in 17 of 20 rabbits. In these animals, the CCA lateral aneurysm model was deemed successful, and biodegradable covered magnesium alloys stents and Willis covered stents were implanted in 9 and 8 aneurysms, respectively. DSA after biodegradable covered magnesium alloys stent placement displayed disappearance of the aneurysms and patency of the CCA in all 9 rabbits during follow-ups. DSA 3 months after Willis stent placement displayed patency of the CCA in 7 rabbits and occlusion of the artery in one. No occlusion of the right CCA was observed on angiography at 6 and 12 months. The degradation of the biodegradable covered magnesium alloys stent was investigated with molybdenum target during follow-ups, and no changes was observed in Willis covered stent. Conclusion Biodegradable covered magnesium alloys stent is a feasible approach for the treatment of a lateral aneurysm in the right CCA.

Objective To observe the syndrome manifestations of rabbit atherosclerosis models and explore the syndrome attribution rules of the models.Methods The 24 male Japanese rabbits were randomized into a control group(n=8)and a experimental group(n=16).The control group was given normal feed,and the experimental group was treated with high-fat diet and immune injury and surgical injury through the femoral artery balloon.They were fed totally for 10 weeks.Vascular morphological changes and blood lipid determine were used to evaluate the models.The ear,tongue,eye,and the overall state of rabbits were regularly observed to see the changes of TCM syndromes.Results The rabbits of the experimental group gradually reduced the amount of activity in early stage.When the climate changed,their nasal secretion was increased,and they had wheezing breathing,fever and other common cold symptoms like red auricle.In the medium stage,the fatty plaque or belt around the eyes,cold auricle,and listlessness could be seen,and the blood fat was significantly higher than that of the control group.To the tenth week,the dark tongue with blood spots and purple cold auricle appeared in the rabbits of the experimental group.It was difficult to draw blood from the ear,and the emboli could be seen in the vessels of auricles.Compared with the control group,the oxidized low density lipoprotein and malondialdehyde of the experimental group were significantly increased,and the activity of superoxide dismutase decreased.Conclusion The syndromes of rabbit atherosclerosis models are in the changing state,in early stage they can be manifested as Qi deficiency,in middle stage the manifestation can be Qi deficiency with phlegm retention,and in late stage there will be Qi deficiency with blood stasis.The rule is similar to that of the pathogenesis of atherosclerosis in clinic.

Objective:To observe whether the Simiao Yongan Decoction regulate the nuclear factor-?B(NF-?B) expression and related factors in atherosclerosis(AS)rabbit model,thus restrain the occurrence of atherosclerosis and plaque formation.Methods:56 male Japanese rabbits were randomly divided into normal group,model group,Simvastatin group and Simiao Yongan Decoction group,in addition to the normal group,other groups were established aortic atherosclerotic plaque model.From the1st day of experiment,the corresponding drug intervention began,10 weeks later,the rabbits were killed over the weekend after the anesthesia line access aortic NF-?B immunohistochemical staining,and the experimental dynamic 0,3,6,10 weeks in serum TNF-?,IL-1 and MCP-1 content.Results:The expression of NF-?B p65 subunit in model group was rich,and compared with it,the expression of NF-?B p65 subunit in treatment groups decreased,and the Simiao Yongan Decoction can obviously inhibit the expression of NF-?B p65 subunit.In model group,the expressions of IL-1,TNF-?and MCP-1 in serum increased significantly at different time points(P

Objective To investigate the expression of transforming growth factor beta (TGF-β) and Smad signaling in ankylosing spondylitis (AS) and to explore their roles in the pathogenesis. Methods Fiftythree patients with AS were included in the study. In these 53 cases, 30 patients were performed computed tomography-guided needle biopsy in sacroiliac joint. Serum TGF-β_1 was determined by enzyme-linked immunosorbent assay (ELISA). Immunohistological studies were performed with the streptavidin-peroxidase conjugated methods to assess the expression of TGF-β_1, p-smad3 and Smad7 in sacroiliac joint tissue sample.One-way ANOVA, two independent samples t test and kolmogoorov-Simimov test were used to do statistical analysis. Results In 53 cases patients with AS, 20 cases were with high level Erythro-cyte sedimentation rate(ESR) and C-reactive protein (CRP), while those of the other 33 cases were normal. Serum average TGF-β_1level [ (15.9±5.6) ng/ml ], in patients with high level ESR/CRP [(5.4±5.8) ng/ml ] was significantly increased as compared to the controls and patients with normal ESR/CRP [(4.1±3.6) ng/ml] (P<0.05). There was no expression of TGF-β_1 could be detected in the pannus and bone marrow in SI joints tissue of 30 cases with AS, while decreased level of smad7 expression was detected. In addition, p-smad3 expression was found in the nuclear. Conclusion TGF-β_1 signaling may play an important role in the inflammatory erosion and cartilage fibrosis of sacrojlitis in AS.

Objective:To investigate the clinical phenotype and genetic characteristics of patients with Fabry disease caused by a GLA variant, IVS4+919G>A.Methods:It was a prospective study. Fabry disease screening was conducted among high-risk population in Ninghai from October 2021 to August 2023. Those children with decreased α-galactosidase enzyme activity<2.40 μmol/(L·h) or elavated Lyso-GL-3 level>1.10 μg/L in dried blood spot (DBS) method underwent GLA genetic testing for diagnosis confirmation. Meanwhile, family screening was carried out. A proband and his family members diagnosed with Fabry disease were research subjects. The clinical and genetic characteristics of patients with Fabry disease caused by the GLA variant (IVS4+919G>A) were analyzed.Results:The female proband aged 9.8 years with pain in both lower limbs as the initial symptom was found to have a heterozygous GLA variant IVS4+919G>A among 102 patients. In family screening, there were 4 family members (proband's father, elder sister, elder male cousin and elder female cousin) with Fabry disease and a family member (proband's fifth aunt) with a GLA variant. Among these 4 diagnosed family members, the elder male cousin of the proband, a boy aged 13.2 years had a heterozygous GLA variant, IVS4+919G>A with intermittent pain in both lower limbs as the initial symptom. The proband′s father had knee joint pain. The proband′s elder sister had decreased vision and his elder female cousin had no obvious symptoms. The proband′s fifth aunt with a GLA variant had decreased vision.Conclusions:High-risk screening in children and family screening are helpful for early diagnosis and treatment of Fabry disease. Neuropathic pain may be a early symptom in children with Fabry disease caused by the GLA variant, IVS4+919G>A.
