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 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 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 analyze the outcomes and postoperative complications of renal transplant recipients of ethnic minorities and Han population in China, and investigate the differences between them. Methods Clinical data from 89 minority patients and 100 Han patients who had received renal transplant of Hans' donators in Organ Transplantation Center of PLA from 1990 to 2012 were retrospectively analyzed. The general data before transplantation, and rate of short-term survival of the graft, incidence of delayed graft function (DGF), acute rejection, and pulmonary infection after transplantation were analyzed and compared. Results No statistical difference was found in the preoperative personal profile between the recipients of minorities and Han nationality. In the recipients of minorities and Han nationality, the 1-year graft survival rate was 89.9% and 92%, the respective incidence of DGF was 28.1% and 27.0%, and the respective incidence of acute rejection was 22.5% and 19.0%, and there was no significant difference between them (P>0.05). The incidence of pulmonary infection was higher in minority recipients (30.3%) than in Han recipients (10.0%, P<0.01), but no significant difference was found between Tibetan, Hui, Manchu and Mongolian recipients in 1-year graft survival rate, incidence of DGF, acute rejection and pulmonary infection (P>0.05). Conclusion The short-term clinical outcome of renal transplant recipients seems to be similar in different Chinese ethnic groups, but the incidence of pulmonary infection is higher in minority recipients, so it is important to strengthen monitoring in early postoperative period.

Objective To study the value of 3D-CT reconstruction in the diagnosis of surface involved lesions of bone for its nature and location,comparing with plain film and 2D-CT.Methods Surface-involved lesions of bone revealed by plain-film were performed spiral CT examination.Multi-planar reconstruction(MPR)and surface shading display(SSD)were performed among 20 cases which had pathologic results.The diagnosing correct rate of nature and location in all the techniques were compared.Results The correct rate of nature diagnosing of plain film,2D-CT,MPR and SSD was 75%,80%,65%,60% respectively;correct rate of location diagnosing was 90%,75%,85%,95% respectively.The highest nature diagnostic correct rate was found in 2D-CT.The highest location diagnostic correct rate was found in SSD.Conclusion Spiral CT stereoscopic reconstruction is of great value in the location diagnosing of surface-involved bone lesion.

Objective:To investigate the eye movement anormalities of Obsessive-Compulsive Disorder (OCD) and their possible clinical significances. Methods: Exploratory eye movement in 57 patients with OCD according to DSM-IV criteria (27 medicated, 30 un-medicated) and 50 normal controls matched with sex, age and education were examined respectively. Results: Compared with normal controls, patients with OCD demonstrated low scores in most of the indices of exploratory eye movement. The rates of positive discrimiant score in OCD and normal controls were 37%(21/57) and 8% (4/50), respectively (X2 = 12.27, P

Objective To study the clinical applied value of computed tomography perfusion imaging(CTPI) in early stage of ischemic stroke.Methods Routine CT scan and CTPI were performed in 45 patients with early stage of ischemic stroke(onset within 24 hours).CTPI yields a set of perfusion related parameters of relatine cerebral blood flow(rCBF), cerebral blood volume(rCBV),mean transmit time(rMTT),time to peak(rTTP) and positive enhancement integral (rPE).Results In all 45 patients,21 cases showed concerning lesions in the 29 cases with cerebral ischemia results of routine CT scan.16 cases presented normal results. 24 cases were not showed concerning lesions.The sensitivity of diagnose for early stage of ischemic stroke by CT was 46.67% (21/45).The specificity was 72.41% (21/29).44 cases of CTPI with abnormal perfusion changes were all showed concerning lesions. Only one case of CTPI presented negative result,which was acute brainstem infarction confirmed by follow-up magnetic resonance imaging (MRI).The sensitivity of diagnose for early stage of ischemic stroke by CTPI was 97.78% (44/45).The specificity was 100% (44/44).There was significant difference between CTPI and routine CT scan(P
