ABSTRACT
Hepatocellular carcinoma (HCC) is the most common primary liver cancer, and its high mortality rate is closely associated with the unsatisfactory diagnostic and monitoring methods for HCC at present. Some microRNAs (miRNAs) play an important role in the development and progression of HCC, and their abnormal expression is a common phenomenon in HCC pathology; in addition, miRNAs can be released into the circulating blood and remain stable in blood. By reviewing the research advances in the role of miRNAs in HCC, it is pointed out that miRNAs are expected to become potential markers for the early diagnosis, monitoring and treatment, and prognostic evaluation of HCC, and this article also analyzes related issues in the clinical verification of such potential markers.

ABSTRACT
Objective To investigate expression and role of tissue factor pathway inhibitor -2(TFPI -2)in normal cervix,cervical intraepithelial neoplasia(CIN)and cervical squamous cell carcinoma.Methods From Janu-ary 2011 to December 2012,114 patients with cervical resection in our hospital were selected,among them,42 patients with cervical squamous cell carcinoma,27 cases with CIN,45 cases of normal cervix.Immunohistochemical method was used to detect the expression of TFPI -2 protein in cervical tissues.Results The expression of TFPI -2 in cer-vical cancer tissues was significantly lower than that in other cervical tissues,the difference was statistically significant (cervical cancer tissues vs.normal cervical tissues χ2 =59.670,P 0.05).There was no significant difference in TFPI -2 expression in cervical cancer tissues with different differentiation levels(χ2 =4.633,P >0.05).Figo Ⅰcervical cancer TFPI -2 expression was significantly higher than Figo Ⅱ cervical cancer,the difference was statistically significant(χ2 =6.509,P <0.05).The expression of TFPI -2 in cervical cancer tissues without lymph node metastasis was significantly higher than that in cervical cancer tissues with lymph node metastasis,the difference was statistically significant (χ2 =10.916,P <0.05).Conclusion The reduction of TFPI -2 expression may be involved in the development of cervi-cal cancer,and the expression of TFPI -2 is associated with the prognosis of cervical cancer.
ABSTRACT
Objective To evaluate mechanical radial scanning endoscopic ultrasonography (EUS) for preoperative tumor and lymph node ( TN ) staging of esophageal cancer. Methods From January 2010 to June 2010, a total of 60 patients with esophageal cancer underwent preoperative staging with mechanical radial scanning EUS. The findings of EUS were compared with postoperative pathological outcomes. Results EUS accurately predicted T stage in 80 % of cases and N stage in 71% cases. Sensitivities to T1 , T2 , T3 and T4 were 75% , 100% , 96% and 50% , respectively, and those to N0 and N1 were 55% and 100% , respectively. With exclusion of 11 patients with un-passable lesions, the accurate rate of EUS in T staging of focal and advanced cancers was 90% ( 44/49 ). Conclusion Mechanical radial scanning EUS can accurately predict T and N stages in preoperative patients with esophageal cancer, which also exhibits high differential accuracy in focal and advanced esophageal cancer.

ABSTRACT
BACKGROUND:Cataract is not the necessary symptom for myotonic dystrophy(DM).But it may be the early and even only clinical symptom of DM.Molecular diagnosis can provide the important evidence for the diagnosis of DM.OBJECTIVE:To explore the characteristics of cataract in 26 patients with myotonic dystrophy of 3 pedigrees from Shanghai Songjiang area.DESIGN:Analysis on the Genealogy of Pedigree.SETTING:Department of Neurology,Shanghai Changhai Hospital.PARTICIPANTS:Twenty-six patients of 3 pedigrees,aged 7 to 71 years old,which were preliminarily diagnosed as DM patients or were suspicious DM patients,admitted to Department of Neurology,Shanghai Changhai Hospital between May 2001 and August 2003,were recruited in this study.Among the involved patients,13 corresponded to the clinical diagnosis standard from Practical Neurology,and the other 13 patients have adverse symptoms and (or) body signs of partial or mild DM,suspecting with DM patients.METHODS:①Peripheral blood of 1 mL was taken and genome DNA was extracted.By using a thermocycler,a polymerase chain reaction (PCR) was carried out to examine the CTG repeats according to criteria of molecular diagnosis (CTG repeats from 80-3350).②In addition,slit-lamp examination for specific lens opacity was carried out and the association between DM and cataract was analyzed.MAIN OUTCOME MEASURES:①CTG trinucleotide repeat numbers.②Association between DM and cataract.RESULTS:Of the 26 patients,25 participated in the final analysis except 1 who suffered from sterility clinically.①25 patients were consistent with the molecular diagnostic criteria of DM (CTG repeats from 80-3 350).The remaining 1 with CTG repeats of 13 was clinically sterility and therefore belonged to the normal individual.The (CTG)n triplet repeats of 17 patients with cataract were 2380±80,while 8 patients with cataract were 2298±105(P＞0.05).②Cataract was characterized as iridescent lens opacity or blue posterior cortical lens opacity in 17 patients.Among the 17 patients,cataract in 8 patients was the only early clinical sign whose(CTG) n triplet repeats were higher than the normal ones.CONCLUSION:In the pedigrees with DM patients,characteristic cataract,as a main and even only early clinical sign,will provide important clinical evidence for the early diagnosis of DM.
ABSTRACT
BACKGROUND: Pergolide and madopar are the effective medicines to treat Parkinson disease, but the effects on the prognosis of patients with Parkinson disease are still under discussion. The progress of neuroimaging makes it possible to evaluate quantitatively the effect of the drug treatment on the prognosis of Parkinson disease.OBJBCTIVE: To observe the influence of pergolide or madopar as initial treatment on the prognosis and the striatal dopaminergic neuron in patients with early Parkinson disease by means of 99Tcm-TRODAT-1 dopamine transporter imaging single-photon emission computed tomtheography (SPECT) in combination with Parkinson disease scale.DESIGN: A randomized grouping, parallel control and placebo control trial.SETTING: Department of Neurology, the 81 Hospital of Chinese PLA;Department of Neurology and Department of Nuclear Medicine, Changhai Hospital of the Second Military Medical University of Chinese PLA.PARTICIPANTS: Thirty-six patients with early Parkinson disease who were recruited at the Specific Clinic of Parkinson Disease in the Shanghai Changhai Hospital affiliated to the Second Military Medical University of Chinese PLA and did not receive any drug treatment before, were enrolled between February and July 2002. They were randomly divided into artane control group (n=12), pergolide-treated group (n=12) and madopar-treated group. The diagnosis accorded with the clinical diagnostic standard set by United Kingdom Society of Parkinson Disease. This protocol was approved by the Medical Ethics Committee of Changhai Hospital, and all the subjects were enrolled in this study with informed consent.INTERVENTIONS: After test with unified Parkinson disease rating scale (UPDRS) and 99Tcm-TRODAT-1 SPECT, patients in the artane control group, pergolide-treated group and madopar-treated group were treated with corresponding drugs respectively, and each capsule of artane, pergolide and madopar contained drug of 0.05, 0.05 and 125 mg respectively. In the 1st week, the dosage was 1 capsule for each time, once a day, and then the daily dosage was increased by 1 capsule per week later, and the daily dosage reached 0.2, 0.2 and 500 mg respectively after 1 month, and then the dosages were kept constant. The curative effects were evaluated with UPDRS at 6 and 10 months after treatment. At 10 months after treatment,the 99Tcm-TRODAT-1 specific intakes of ipsilateral or contralateral striatum of the affected limb were tested with striatum dopamine transporter SPECT and semi-quantitative analysis.MAIN OUTCOME MEASURES: ① Changes of percentage of 99Tcm-TRODAT-1 decrease of ipsilateral or contralateral striatum of the affected limb at 10 months after treatment were compared among the three groups;② Changes of UPDRS scores before and after treatment were compared among the three groups.RESULTS: Totally 36 patients were involved in the study, and 1 case lost in each of the 3 groups respectively at 10 months after treatment, finally 33 cases entered the analysis of results. ① Changes of percentage of 99Tcm-TRODAT-1 decrease of ipsilateral or contralateral striatum of the affected limb at 10 months after treatment: At 10 months after treatment, the percentage of 99Tcm-TRODAT-1 decrease of ipsilateral or contralateral striatum of the affected limb were obviously higher in the madopar-treated group than in the artane control group and pergolide-treated group [(46.3±19.4)%, (28.9±13.0)%, (34.4±18,1)%; (47.5±20.8)%, (31.8±15.6)%, (33.8±17.2)%; P all ＜ 0.05]. ② Changes of UPDRS scores before and after treatment: As compared with the UPDRS scores before treatment, there was no obvious change in the artane control group at 10 months after treatment,but those in the madopar-treated group and pergolide-treated group were obviously decreased [(15.5±8.68), (6.4±9.05); (15.8±6.75), (10.36±8.30); Pall ＜ 0.05].CONCLUSION: Both madopar and pergolide can ameliorate the symptoms of early Parkinson disease, but they had different influences on the prognosis of patients with Parkinson disease. Madopar may accelerate the apoptosis of dopaminergic neuron and then aggravate the severity, but pergolide does not affect the prognosis of Parkinson disease, so it is a more suitable selective drug for the treatment of early Parkinson disease.
ABSTRACT
BACKGROUND: Selegiline can effectively alleviate motor disorder symptoms during the earlier stage of Parkinson disease(PD),but the influence on prognosis is still warmly discussed. With the development of neuroiconologicai study,the objective predictor for dopaminergic neuronal degeneration in PD would became possible.OBJECTIVE: To observe the influence of selegiline on dopaminergic neurons in earlier stage of PD with the aid of iconology.DESIGN: Randomized controlled study based on patients.SETTING: Neurological department in a military hospital of Chinese PLA,the nuclear medicine and neurological department in a military medical hospital of Chinese PLA.PARTICIPANTS: Between April and December 2001,25 patients were selected from PD specific clinic of Changhai Hospital,the Second Military Medical University of Chinese PLA. They were confirmed of earlier stage of PD without given any related drugs.INTERVENTIONS: Totally 25 patients were randomly divided into placebo group of 13 cases and selegiline group of 12 cases. After assessed with unified PD rating scale(UPDRS),they were given placebo and selegiline respectively with the dosage gradually increased from 0.05 mg at the beginning and added with 0.05 mg every week for four weeks until reaching the sustaining dosage of 0.2 mg. Dopamine transporting protein (99Tcm-TRODAT-1) examination and single photon emission-computerized tomography (SPECT) were performed at entering the experiment and after the treatment for 13 months,and semi-quantitative analysis was used for counting striatal emission of the ipsilateral and contralateral side. Scores for UPDRS were obtained at entering the experiment,after the treatment for 6months and 13 months.MAIN OUTCOME MEASURES:①Main outcomes:The differences ofstriatal 99Tcm-TRODAT-1 specific intake decreasing percentage on ipsilateral and contralateral side were compared between the two groups after the treatment for 13 months.②Subordinate outcome:Scores for UPDRS of the two groups was also compared.RESULTS: After the treatment for 13 months,striatal 99Tcm-TRODAT-1 specific intake decreasing percentages were (28.9 ± 13.0)% and(31.8 ± 15.6) % on ipsilateral and contralateral side of placebo group compared with the corresponding (30.39 ± 14. 7)% and(32.6 ± 16. 6)% of the selegiline group,the difference was of no statistical significance( P ＞ 0.05). Scores for UPDR was(23.7 ±4.3) in placebo group and(13.1 ± 5.5) in selegiline group after the treatment for 6 months,and(27.0 ±4.3) and(9. 8 ±4. 8) after the treatment for 13 months,indicating that slegiline group was obviously better than placebo group( P ＜ 0. 05).CONCLUSION: Selegiline showed better therapeutic effect in the treatment of earlier-stage PD without increasing the apoptosis of striatal dopaminergic neurons.

AIM: To compare the effects between topiramate and slow-release sodium valproate in treating refractory epilepsy. METHODS: Topiramate group of 39 patients (M 21, F 18; age 28 a± s 20 a) was compared with sodium valproate group of 41 patients (M 22, F 19; age 27 a±17 a) in antiepileptic effect of refractory epilepsy. Adult's and children's dosages of topiramate were increased gradually about 200 mg*d-1 and 4 mg*kg*d-1 respectively during about 2 mo, po, bid, for 6 mo as a course. Adult's dosage of slow-release sodium valproate was 0.5-1 g*d-1, and children's was increased gradually to total dosage: 15-30 mg*kg*d-1, po, qd or bid (morning or morning and noon), for 6 mo as a course. Effects were analysed between these two drugs after treatment 4 and 6 mo. RESULTS： Simple and complex partial seizures with or without secondary generalized seizure, in topiramate group were much more improved than these in sodium valproate group 6 mo after treatment. Four patients of topiramate group appeared temporary adverse reactions of central nervous system, such as tiredness, sleepiness and distraction, but one patient of sodium valproate group had severer decreased function of bone marrow. CONCLUSION: Topiramate is one of effective antiepileptic drugs and superior to slow-release sodium valproate. There are the apparent absence of any effects of topiramate on the bone marrow and on indexes of liver and kidney.

ABSTRACT
Using 133Xe-inhalation technique quantitative measurements the regional cerebral blood flow (rCBF) was performed in 20 patients with unilateral ischemic lesion in one hemisphere according to cranial CT scan and in 10 normal subjects. Twenty patients had an Ultrasound Doppler examination of neck vessels half a day after rCBF examination. The results showed that rCBF in ischemic hemisphere before and during 3% CO, stimulation was lower than that in normal subjects or in non-ischemic hemisphere of the patients. It suggests that dilative responsibility to CO, in cerebral artery of stroke hemisphere is reduced. That is to say the cerebrovascular reserve capacity in stroke hemisphere was reduced too, but cerebrovascular reserve capacity in the non-stroke hemisphere and in normal subject of control group was normal. We also found cerebrovascular responsibility to CO, or cerebrovascular reserve capacity correlated with severity of clinical cerebral thrombotic illness and extent and degree of internal carotid artery obstruction. It was poor in severe illness or internal carotid obstruction and/or narrow in both sides of the patient group taken by Ultrasound Doppler examination of neck vessels.
