Objective To explore the clinical, imaging and electrophysiological characteristics of Creutzfeldt-Jakob disease ( CJD) .Methods The clinical data of 28 very probable CJD patients were analyzed retrospectively. Results Twenty-eight patients in this group, acute onset was in 5 cases, subacute onset was in 17 cases, chronic onset was in 6 cases.The initial symptoms were dizziness, gait instability in 11 cases ( 39.3%) , cognitive dysfunction in 10 cases (35.7%), visual symptoms in 3 cases (10.7%), mental symptoms, insomnia, repeated falls and barylalia in 1 case (3.6%) respectively.The clinical symptoms were progressive dementia in 28 cases (100%), myoclonus in 21 cases (75.0%), ataxia in 19 cases (67.9%), abnormal mental behavior in 7 cases (25.0%), pyramidal signs in 20 cases (71.4%), extrapyramidal symptoms in 15 cases (53.6%), visual impairment in 6 cases (21.4%), sleep disorder in 11 cases (39.3%), and aphasia in 9 cases (32.1%).Twelve patients (42.9%) had positive results with CSF 14-3-3 protein analysis.Twenty-four patients (85.7%) had MRI high signal abnormalities in caudate nucleus and putamen or/and at least two cortical regions.Eight cases (28.6%) experienced a typical periodic sharp wave complexes (PSWCs), 12 cases (42.9%) had a diffuse symmetric or asymmetric slow-wave activity, 8 cases (28.6%) showed rhythmic three-phase or delta wave, with the whole guide or forehead synchronization.Conclusion Most CJD patients are subacute or chronic onset.Initial symptoms of CJD are atypical, progressed to classical clinical characteristics presented in middle-late stages.Nearly half patients have CSF 14-3-3 protein positive.MRI DWI of mostly CJD patients have abnormal signal.EEG of nearly a third of CJD patients shows PSWCs.

BACKGROUND: Peripheral facial paralysis is treated at present only with traditional traumatic methods, such as acupuncture, moxibustion,needling with physical therapy, point-injection, thread burial therapy,scraping therapy, etc. Those methods do not act directly on the lesion of facial nerve and they are long in duration of treatment and low in curative rate. The constant magnetic aerobic atruamatic method along meridian just makes up the shortcoming of the traditional therapies.OBJECTIVE: To observe the therapeutic effects of constant magnetic aerobic atruamatic method along meridian on treatment of peripheral facial paralysis.DESIGN: Case analysis.SETTING: Department of Facial Paralysis, College of Stomatology, Fourth Military Medical University of Chinese PLA.PARTICIPANTS: Totally 1 500 cases of first diagnosed peripheral facial paralysis were employrd in 18 provinces and autonomic regions in China from June 1998 to June 2004, of which, 935 cases were male and 565 cases female. Of 103 cases were aged varied from 1.5 to 19 years, 1 105 cases from 20 to 50 years and 292 cases from 51 to 74 years. Of 672 cases were left palsy and 828 cases were right palsy. The duration of sickness was varied from 1 day to 40 years.METHODS: Constant magnetic aerobic therapy for 20 minutes was applied on facial-palsy effective points for all of cases [No.1 point: in the depression inferior to mastoid process behind ear lobe on the affected side,corresponding to the mastoid foramen, from which, the facial nerve emerges. No.2 point: on the arch top of mastoid process behind ear lobe on the affected side. No.3 point: about 3.33 cm (1 cun) above No.1 point. No.4: in the conjunction between the point about 0.5 cm posterior to the external auricular tract and the one 0.5 cm inferior to helix cms. No.5 point:about 1 cun anterior to ear apex. No.6 point: on the top of the upper border of helix on the affected side] and supplementary points [Qianzheng (Extra),Dicong (ST 4), bilateral Hegu (LI 4)], once per day, 10 days makes one course. There were a couple of days at interval between two courses, totally two courses were required. Point and oxygen therapies were applied simultaneously. Oxygen therapy: 20 minute/time, once per day, 10 days made one course, at the volume of oxygen 2-4 L/minute. Evaluation of therapeutic effects: It was to compare the changes between the affected side and healthy side in forehand wrinkles, frowning, closing eyes, whistling, blowing and smiling and the changes between two sides in nasal labial groove and philtrum during showing the teeth and at static state. Comparison of bilateral muscularis function of healthy people and patients were obtained with the six-point and four-line measurement.MAIN OUTCOME MEASURES: Results of evaluation on clinical therapeutic effects.RESULTS: Totally 1 500 cases of peripheral facial paralysis entered result analysis, no dropped out case. After 20 days treatment, 1 385 cases (92.33%) were recovered, 92 cases (6.13%) appeared significant effect, 22cases (1.74%) were improved and 1 case (0.07%) was no effect. The total effective rate was 99.93%.CONCLUSION: Constant magnetic field in combination with oxygen therapy is characterized as no pain, no trauma, no cross infection and no second injury of facial nerve, safe and convenient operation, short duration of treatment and high curative rate. It improves remarkably the symptoms of facial paralysis and recovers facial function.

Objective To construct eukaryctie expression vectors stably expressing Smad-7 and study its function as TGF-β1 inhibi- tor. Methods Smad-7 genes were obtained by PCR from fetal liver cDNA library and inserted in to eukaryotic expression plasmid pcD- NA3. 1/myc-his-B (-). The constructed plasmids containing right sequence of target genes were transfected into human mesangial cells by lipofectamine. The ceils were selected by G418, the expression of Smad-7 was detected by Western-blotting. Cell proliferation was detected by MTT method, and cell cycle was detected by Flow Cytometer to study its function as TGF-β1 inhibitor. Results We successfully con- struct Smad-7 expression plesmid. Smad-7 can inhibit the effects of TGF-[M induced GI cell cycle block and apoptosis. Conclusion The eukaryotic expression vector of Smad-7 has been successfully constructed. Over-expression of exogenous Smad-7 can inhibit the effects of TGF-β1 induced GI cell cycle block and apoptosis.

Objective To observe the effect of tanshinoneⅡA (TⅡA) on arrhythmia and levels of ischemia modified albumin (IMA) and heart type-fatty acid binding protein (H-FABP) in rats with myocardial ischemia-reperfusion injury.Methods Forty Wistar rats were equally randomized into 5 groups:pseudo-operation group (normal saline),model group (normal saline),and high-,middle-and low-dose TⅡA groups (in the dose of 20,10 and 5 mg?kg-1?d-1 respectively).The rats were treated for 7 days,and received operation 2 hours after the last medication.Rats in pseudo-operation group received threading without ligation,while animal model of myocardial ischemia-reperfusion injury was established by ligating the left-anterior coronary artery for 15 minutes and then loosening for 30 minutes.During the operation,electrocardiogram was traced continuously to observe the arrhythmia.HE staining was used to observe the pathological changes of myocardium.Levels of IMA and H-FABP in myocardium were determined by enzyme-linked immunosorbent assay (ELISA).Results Ischemic changes of the myocardium and arrhythmia occurred,myocardial IMA level increased and H-FABP level decreased in the model rats.TanshinoneⅡA obviously attenuated arrhythmia caused by ischemia-reperfusion injury (P

Objective To detect the apoptosis and the intensity of proliferation in different types of renal pathology in children with lupus nephritis (LN), analyzed the relationship between apoptosis and proliferation in LN. Methods Twenty - seven children (aged 7-16 years old, 21 type IV and 6 type V ) with biopsy- proven LN and nine as controls were included in the study. Apoptosis was detected by in situ nick- end labeling techniques (TUNEL) in renal biopsy samples. Immunohistochemistry was employed to detect the proliferating cells identified by proliferating cell nuclear antigen (PCNA) and detect the expressions of proteins of apoptosis associated gene PDCD5 and Caspase - 3 in these patients. Results 1. Compared to type V LN, the patients with type IV LN had more apoptolic cells,more PCNA positive cells and higher ratios of PCNA/apoptosis (P/A) in glomeruli. 2. There were no difference in expression of PDCD5 in glomeruli in type IV LN compared with those in type V LN. Numbers of apoptotic cells were observed in glomeruli. The expression of Caspase- 3 in type IV LN increased in glomeruli compared with that in type V LN. Conclusions The up- regulation of mechanism of apoptosis in type IV LN was less than that of type V LN. Caspase- 3 participated in the apoptosis of glomeruli of LN, but PDCD5 did not play a role during apoptosis of glomeruli of LN or the effect of PDCD5 promoting apoptosis was depressed.
