Objective To identify the clinical and neurophysiological features of multiple system atrophy (MSA) and explore diagnostic values using various techniques in electro neurophysiology Methods Forty four subjects diagnosed as multiple system atrophy (MSA) during 1983 to 2001 in PUMC Hospital were studied retrospectively about their clinical features, routine electromyography (EMG), nerve conductive velocity (NCV), somatosensory evoked potential (SEP), motor evoked potential (MEP), brainstem auditory evoked potential (BAEP) and visual evoked potential (VEP) The clinical features and the electroneurophysiologic results were analyzed in different subgroups (probable MSA and possible MSA, OPCA and non OPCA, classified MSA and unclassified MSA) Results Most patients were found to be suffered from autonomic failure (88 6%) and cerebella dysfunction (88 6%) The pyramidal sign was seen in 72 7% of patients No remarkable statistical differences were found in all of the above three domains The incidence of Parkinsonism was 36 4% of all the patients, which showed significant differences between probable and possible MSA (54 5% vs 18 2%), non OPCA and OPCA (50% vs 7 1%), unclassified MSA and classified MSA (52% vs 15 8%) EMG was abnormal in 7 patients (38 1%), all of them were neurogenic impairments The rates of abnormal EMG were varied differently between probable and possible MSA (54 5% vs 22 2%), non OPCA and OPCA (53 8% vs 14 3%), unclassified MSA and classified MSA (58 3% vs 12 5%), but without statistical differences The abnormal rates in BAEP,SEP, VEP and MEP were 56 7%, 28%, 23 1% and 20 0%, respectively, and there were no significant differences between subgroups Conclusions It should be hard to divide MSA into groups only by the clinical manifestations All EPs were abnormal in some extent The most sensitive test is BAEP in current study, but there were no differences among the subgroups in the rates of abnormal EPs The difference of EMG and NCV between the groups showed that the technique might be helpful in the diagnosis of MSA

Objective To explore the clinical significance of combination detection of serum squamous cell carcinoma antigen (SCC-Ag) and carcino-embryonic antigen (CEA) for the diagnosis,effect evaluation,monitoring and prognosis in cervical carcinoma.Methods Four hundred and twenty-four cases of cervical carcinoma patients diagnosed by pathology and 400 binign gynaecology patients were selected to detect levels of SCC-Ag and CEA by ELISA.Besides,the pelvic color ultrasound results of cervical carcinoma patients were collected and analyzed.Results The positive rates of serum SCC-Ag,CEA and combined detection of cervical carcinoma patients were 55.9 ％(237/424),26.4 ％(112/424),61.8 ％(262/424),which were higher than those of binign gynaecology patients [12.0 ％(48/400),12.5 ％(50/400),14.5 ％(58/400)],and the differences were statistical significance (all P＜ 0.05).The sensitivity of combined detection of SCC-Ag and CEA for diagnosing cervical carcinoma (61.8 ％) was better than that of detection of alone SCC-Ag or CEA (55.9 ％,26.4 ％),and the difference was statistical significance (P ＜ 0.05).The differences of pretreatment serum SCC-Ag and CEA levels in the cervical carcinoma patients who were dependent on clinical stage,pathological type,depth of invasion,lymph node metastasis were statistically significant (all P ＜ 0.05).The combined detection of SCC-Ag and CEA in patients with stage Ⅰ and Ⅱ had higher positive rates [45.5 ％ (71/156),73.2 ％(139/190)] than those of the ultrasound examination [33.3 ％(52/156),51.1％(97/150)] (P＜ 0.05).After surgery or concurrent chemoradiotherapy or surgery combined radiation and chemotherapy,SCCAg levels of patients in post-treatment (median 0.34,0.51,0.33 ng/ml) were much lower than those of pretreatment (median 0.48,3.44,1.29 ng/ml),and CEA levels of post-treatment (median 0.75,0.81,0.71 ng/ml)were also lower than those of pre-treatment (median 1.22,1.53,1.50 ng/ml) (P ＜ 0.05).After treatment,cervical cancer patients with the raised or not decreased to the normal range levels of SCC-Ag and CEA had recurrences or metastasis rates of 33.3 ％(6/18),56.5 ％(13/23) and 46.1％(35/76).Survival rate of the patients with positive SCC-Ag was significantly lower than that of patients with negative (P ＜ 0.05),while the survival rate of patients with positive or negative CEA had no difference (P ＞ 0.05).Conclusions Combined detection of SCC-Ag and CEA can be used as an important indicator to estimate clinical stage,pathological type,depth of invasion,lymph node metastasis,curative effect and prognosis of cervical carcinoma.Combined detection of SCC-Ag and CEA had higher positive rates than pelvic color ultrasound examination for cervical carcinoma patients in stage Ⅰ and Ⅱ.

Immunological imbalance is the foundation for the development of liver damage or fibrosis.Therefore,the treatment of liver disea-ses not only relies on regenerative medicine for cellular replacement,but also depends on immunoregulation.The immunological basis of liver injury and repair,the immunological basis of multipotent stem cells for allograft,and the research advances in the immunoregulatory effect of stem cells in the treatment of liver diseases demonstrated that multipotent stem cells,especially mesenchymal stem cells,have low immuno-genicity and cause immunosuppression,with the immunological basis of allograft;in addition,they can improve the local immune microenvi-ronment of the liver by immunoregulation to reduce the liver injury caused by immune response.It is suggested that multipotent stem cells, which meet the requirements of cellular replacement and immunoregulation in the liver,will become an ideal treatment of liver diseases.

OBJECTIVE:To systematically review the efficacy of ursodeoxycholic acid(UDCA)in the prevention ofulcerative colitisassociated colorectal cancer (UC-CRC) and dysplasia (UC-Dys),and provide evidence-based reference for clinic. METH-ODS:Retrieved from Cochrane Library,EMBase,PubMed,CJFD,CBM,VIP and Wanfang Database,randomized controlled tri-als(RCT)or cohort studies about UDCA(test group)versus placebo(control group)in the prevention of UC-CRC and UC-Dys were collected. Meta-analysis was performed by using Rev Man 5.3 software after quality evaluation and data extraction by Co-chrane Manual 5.1.0. RESULTS:Totally 7 studies(3 randomized controlled trials and 4 cohort studies)were included in the analy-sis,involving 672 patients. Results of Meta-analysis of 3 RCT showed that there was no significant difference in the incidence of UC-CRC and UC-Dys between 2 groups [OR=0.95,95%CI(0.17,5.12),P=0.95];results of Meta-analysis of 4 cohort studiess-howed that there was no significant difference in the incidence of UC-CRC and UC-Dys between 2 groups[OR=0.74,95%CI(0.30, 1.84),P=0.52]. Results of subgroup analysis showed,the incidence of UC-CRC and UC-Dys in test group with low-dose UDCA (<15 mg/kg) was significantly lower than control group,the difference was statistically significant [OR=0.19,95%CI(0.08, 0.49),P<0.001];there were no signifficant diferences in the incidence of UC-CRC and UC-Dys in high-dose UDCA group[OR=1.97,95%Cl(0.53,7.25),P=0.31](≥15 mg/kg). There was no significant difference in the incidence of adverse reactions(P>0.05). CONCLUSIONS:UDCA can not decease the incidence of UC-CRC and UC-Dys,it only prompts a possible trend toward decreased UC-CRC and UC-Dys risk in low-doseUDCA.

Objective To study the health state and service of the elderly in the Tongbai community. Methods The educational degree, disease histories, daily living capability, health care demand and the controlled state of hypertension and diabetes were recorded by questionnaires and physical examination. Results Overweight or obesity (66.1%) was the common disease, hypertension (42.2%) next, then coronary disease (10.0%) and diabetes (9.1%). Nearly 43.3% hypertension patients never or seldom measured their blood pressure. The rate of ideal blood pressure was lower than 25%. 30.4% diabetes patients never or seldom measured their fasting glucose and 69.3% patients never or seldom measured their post-meal glucose. 46.1% of the elderly required one or more kinds of community health services, in which annual health examination was 32.6%, and the next was health guide (23.0%), 53.9% of the elderly had no requirement of community services except medical care. Conclusion The elderly in community had high prevalence and poor control of chronic diseases. They did not fully understand the community health services, which brought the challenges to the medical care, health prevention, health education and reasonable utility of hygiene resources in community health services.

The respective sense and antisense oligodeoxynucleotides and their phosphorothiods, targeting at the bcr/abl, were the hallmark gene of Chronic Myelogenous Leukemia( CML) and c-myb correlates with CML. K562 cells, derived initially from a patient of CML blast crisis, were incubated with bcr/abl antisense oligodeoxynucleotides asODN or c-myb asODN or with both asODN in combinalion. All kinds of asODN could not only significantly inhibit K562 cells survival with the highest inhibitory rate of 64.7%?3.2%, but also dramatically inhibit DNA synthesis and the highest inhibitory rate was 85. 8 %?4.1%, decrease bcr/abl mRNA level almost completely and induce apoptosis significantly. The inhibition effect of antisense oligodeoxynucleotides phosphorothiodes s-asODN was stronger than that of unmodified asODN. The inhibition of the combination of bcr/abl and c-myb asODN was stronger than that of anyone alnoe. All the inhibitions exhibited in sequence-and time-dependent manner. We concluded that bcr/abl in pathogenesis of CML not only increased CML cells proliferation rate, but also decreased CML cells apoptosis rate. c-myb may participate in CML mainly by regulating bcr/abl. Trie results indicated that the modified asODN and multiple asODN targeting several oncogenes may advance to antisense gene therapy.

Objective To study congenital transmission of Trichinella spiralis in mice and observe the protection of anti-Trichinella antibodies from the infected dams to challenge infection. Methods According to the gestation (fertilization), the Kunming mice were divided into two groups: the infected group after gestation and the gestated group after infection. New-born mice were cut into small pieces to separate the larvae within 1 day after birth. One-day-old offspring born to normal dams were nursed by the infected dams, slaughtered after 21 days and examined for the larvae. Serum anti-Trichinella antibody level in offspring born to the infected dams was assayed by ELISA at different time after birth, and its immune protection against challenge infection was studied. Results Out of 6 offspring born to the dams infected at 7 days after fertilization, two were found to be infected. Among other female mice which were first infected with T. spiralis and then gestated, only the offspring born to the dams fertilized at 8 and 22 days after infection were found to be infected, the infection rate of offspring was 20% (2/10) and 25%(2/8) respectively. All larvae recovered from the young were non-encapsulated. The cross-fostering experiment showed that none of 30 offspring born to normal dams were found to be infected. The serum antibody positive rate in 27 offspring born to the infected dams at 1, 7, 24, and 40 days after birth was 100%, 100%, 77.8% and 14.8%, respectively. The worm reduction rate in the offspring 40 days after birth was 62.0% after challenge infection. The worm reduction rate in mice in which sera from the offspring born to the infected dams were passively transferred was 55.7%, there was a significant difference (P
