OBJECTIVETo probe into an effective therapy for treatment of cerebral palsy of involuntary movement.

METHODSSixty cases were randomly divided into two groups, the control group was treated with routine rehabilitation method (Bobath + Tuina + scalp acupuncture), while the observation group was treated with plum-blossom needle on Governor Vessel and point Jiaji (EX-B 2) on the basis of routine rehabilitation method. After 3 months of treatment, therapeutic effect, total percentage of Gross Motor Function Measurement (GMFM), incurvation reflex and muscular tension fluctuation were compared.

RESULTSThe obvious effective rate of 53.3% (16/30) in the observation group was superior to that of 20.0% (6/30) in the control group (P < 0.05); the total percentage of GMFM increased, incurvation reflex disappeared, muscular tension fluctuation relieved in both groups after treatment (P < 0.05, P < 0.01), but the indices above all improved more significantly in the observation group than those in the control group (P < 0.05, P < 0.01).

CONCLUSIONPlum-blossom needle on Governor Vessel and point Jiaji (EX-B 2) on the basis of routine rehabilitation method for treatment of cerebral palsy of involuntary movement can enhance the gross motor function, make the incurvation reflex disappear effectively, relieve the muscular tension fluctuation.

OBJECTIVETo investigate the feasibility of treatment for calculous pyonephrosis with first stage percutaneous nephrolithotomy under the standard access.

METHODSThirty-six cases of calculous pyonephrosis and 36 cases of urolithiasis with no pyonephrosis were treated by percutaneous nephrolithotomy. In the nephrostomy, the caliber was dilated to F24. All the operations were preformed through the EMS lithotrity system. The intrapelvic pressure was detected in the operation. The hemoculture before and after operation, the germi culture of urine, and the temperature and blood leucocyte changes after operation were recorded. All the patients were treated by antibiotics before and after the operation.

RESULTSAll the patients were treated successfully. The average intrapelvic pressure were 23.2 cmH(2)O in non-pyonephrosis group and 22.8 cmH(2)O in pyonephrosis group. Both of the groups had 1 case of transient bacteremia after the operation. No significant difference was found in the other indices between the two groups.

CONCLUSIONEMS lithotrity system is safe and feasible for treating calculous pyonephrosis with stage I percutaneous nephrolithotomy via the standard access.

The present study was to investigate the effects of agmatine (Agm) on free intracellular calcium concentration ([Ca(2+)]( i )) of isolated rat ventricular myocytes. [Ca(2+)]( i ) was measured by confocal microscopy in single rat ventricular myocytes which were dissociated by enzymatic dissociation method and loaded with Fluo 3-AM. The changes in [Ca(2+)]( i ) were represented by fluorescence intensity (FI) or relative fluorescence intensity (F/F(0)%). The results showed that the control level of FI value of single rat ventricular myocytes was 128.8+/-13.8 and 119.6+/-13.6 in the presence of normal Tyrode's solution containing Ca(2+) 1.0 mmol/L and Ca(2+)-free Tyrode's solution, respectively. There was no difference between these two groups (P>0.05). Agm 0.1, 1, and 10 mmol/L significantly reduced the [Ca(2+)]( i ) in both extracellular solutions in a concentration-dependent manner. The similar effect of Agm on [Ca(2+)]( i ) was also observed in the presence of EGTA 3 mmol/L. KCl 60 mmol/L, PE 30 micromol/L, and Bay-K-8644 10 micromol/L, all these substances induced [Ca(2+)]( i ) elevations in ventricular myocytes. Agm (0.1, 1, and 10 mmol/L) markedly inhibited the increase in [Ca(2+)]( i ) induced by KCl, phenylephrine (PE), and Bay-K-8644. When Ca(2+) waves were produced by increasing extracellular Ca(2+) concentration from 1 to 10 mmol/L, 1 mmol/L Agm could block the propagating waves of elevated [Ca(2+)]( i ), and reduce the velocity and duration of propagating waves. These results suggest that Agm possesses an inhibitory effects on [Ca(2+)]( i ) via blocking voltage-dependent Ca(2+) channel, and possibly by alleviating calcium release from SR in single isolated rat ventricular myocytes.

The effects of low concentration of dihydroouabain (DHO) on intracellular calcium concentration ([Ca(2+)](i)) were investigated in guinea pig ventricular myocytes. [Ca(2+)](i) was detected by confocal microscopy and represented by fluorescent intensity. DHO (1 fmol/L~1 mmol/L) increased [Ca(2+)](i), especially at 10 pmol/L. Nisoldipine, egtazic acid, or tetrodotoxin partially inhibited the effect of 10 pmol/L DHO on [Ca(2+)](i). The effects of DHO remained in the absence of extracellular K(+) and Na(+). These results suggest that low concentration of DHO might increase [Ca(2+)](i) via the receptor-operated Ca(2+) channels, TTX-sensitive Na(+) channels or/and triggering of intracellular calcium release; Na(+)/K(+) pump and Na(+)/Ca(2+) exchange seem not involved in the effect of DHO.

The aim of the present study was to explore the effect of cholecystokinin octapeptide (CCK-8) on [Ca(2+)](i) and its signal transduction mechanism in isolated guinea pig cardiomyocytes. [Ca(2+)](i) was measured by laser scanning confocal microscopy in single ventricular myocytes which were dissociated by enzymatic dissociation method and loaded with Fluo 3-AM. The changes in [Ca(2+)](i) were represented by fluorescent intensity (F(i)) or relative fluorescent intensity (F(i)/F(O)%). The results obtained are as follows. (1) In the normal Tyrode's solution containing 1.0 mmol/ L Ca(2+), CCK-8 (1-10(4) pmol/L) elicited a rapid and marked increase in [Ca(2+)](i). (2) When cardiomyocytes were pretreated with the Ca(2+) chelator EGTA (3 mmol/L) and Ca(2+) channel antagonist nisoldipine (0.5 micromol/L) for 5 min, CCK-8 (10(2)pmol/L) caused a slow and small increase in [Ca(2+)](i) (p< 0.01). (3) Pretreatment with the nonselected CCK- receptor (CCK-R) antagonist proglumide (6 micromol/L) or the tyrosine kinase inhibitor genistein (1 micromol/L) for 5 min could inhibit the increase of [Ca(2+)](i) induced by CCK-8 (10(2) pmol/L) (p<0.01). The results suggest that CCK-8 increases the [Ca(2+)](i) via activating the receptor-operated Ca(2+) channel and eliciting the influx of Ca(2+) in isolated guinea pig cardiomyocytes, in which tyrosine kinase may be involved.

OBJECTIVETo evaluate the reliability of different hepatitis E diagnosis reagent tests on the acute hepatitis E.

METHODSThree acute hepatitis E diagnosis tests, E2-IgM (Wantai, China), GL-IgM and GL-IgG (Genelabs, Singapore) were compared for their reliability in a sera panel composed by 273 healthy individuals and 525 hepatitis.

RESULTSThe specificity of E2-IgM on the diagnosis of acute hepatitis E was 100.0%, it was significantly higher than GL-IgM (96.7%) and GL-IgG (85.4%). The sensitivity of E2-IgM and GL-IgG were 97.9% and 93.8% respectively, both significantly higher than GL-IgM (72.9%). Among 65 acute hepatitis cases being positive on GL-IgM test but negative on E2-IgM, 58 (89.2%) cases were found to be positive with anti-hepatitis A virus IgM, it indicated that the GL-IgM test might be interfered by other IgM antibodies on serum.

CONCLUSIONE2-IgM is a good test for the diagnosis of acute hepatitis E.

OBJECTIVETo determine the relative resistance to HIV-1 infection of CD4 + T lymphocytes in HIV-exposed seronegative individuals (ESNs) in China.

METHODSHIV primary isolates were obtained from peripheral whole blood of HIV-infected persons. CD4 + T lymphocytes of Chinese ESNs were separated from peripheral blood mononuclear cells with magnetic cell sorting (MACS). The purified CD4 + T lymphocytes were cocultured with HIV primary isolates. The p24 level was detected and the culture medium was refreshed every 3 days within 2 weeks.

RESULTSFor M tropic HIV strains, p24 level was significantly lower in ESN group than in control group (P < 0.05); for some M tropic HIV strains, even no p24 replicated in ESN group. However, T tropic virus strains had no significant difference between these two groups (P > 0.05).

CONCLUSIONCD4 + T lymphocytes of Chinese ESNs may possess relative resistance to M tropic HIV strains, which may be one of the main influencing factors that result in ESN.

OBJECTIVETo investigate the role of first pass dynamic 16-slice spiral computed tomography in the evaluation of tumor angiogenesis in patients with non-small cell lung cancer (NSCLC) and to assess its importance in predicting pathologic characteristics.

METHODSThe first pass dynamic 16-slice spiral computed tomography was performed in 33 patients with NSCLC. Their peak heights (PH) were measured with dynamic evaluation software. Their angiogenesis were labelled by anti-CD34 monoclonal antibody. The first pass peak heights (PH) in 33 patients with NSCLC were compared with their microvessel densities (MVD) and their relationships were assessed by linear regression analysis.

RESULTSAmong the 33 patients with NSCLCs, the mean first pass PH and MVD of N1-2 were significantly higher than those at stage No (P < 0.01). The first pass PH of 33 NSCLC was correlated positively with MVDs. To differentiate stage N0 from stage N1-2 with 12 HU cutoff value of the first pass PH, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 88.0%, 75.0%, 84.8%, 91.7% and 66.7%, respectively.

CONCLUSIONThe first pass dynamic contrast enhanced CT may be a predictor of tumor angiogenesis in patients with NSCLC and its pathologic characteristics, and may be helpful to improve the accuracy of lymph node staging with conventional CT.

The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.

OBJECTIVETo investigate and analyze the therapeutic level and the existing problems on acute myocardial infarction (AMI) management in Beijing.

METHODSWe collected clinic data of 1242 AMI patients from 12 hospitals in Beijing, from January 2000 to March 2001, using a uniformed questionnaire, and evaluated the status of the diagnosis and treatment of AMI according to the Chinese guidelines issued on Decmeber 2001. Corresponding factors which influencing the mortality were also analyzed by one-way factor and multiple factors analysis methodologies.

RESULTSThe mean age of the 1242 AMI patients was 63.0 years old and about one third of them were under 55 years old. In hospitals, the total mortality was 9.10%. 37.9% of the patients had received therapy of the intravenous thrombolysis and emergency PCI with a total rate of reperfusion therapy as 56.0%. The in-hospital rates of drug use were as follows: Nitrates 90.0%, Aspirin 87.8%, heparin 88.7%, beta-blockers 73.4%, angiotensin converting enzyme inhibitors(ACEI) 77.6%, lipid regulating agents 43.6%. The rate of intravenous therapy of TCM by promoting the blood circulation and supplementing the vital energy was 30.5%. Results from multiple factors analysis showed that the compositive factors which could lower the mortality were reperfusion therapy,lipid regulating agents, intravenous therapy of TCM, beta-blockers, ACEI, lower molecule heparin and digitalis.

CONCLUSIONData from this study showed that there still existed a gap between clinical management on AMI and the guideline in Beijing. To set up a straightway passage of reperfusion therapy, to become more standardized to follow the guideline in undertaking the medical treatment practice, and to go deep into discuss the status of TCM on AMI management seemed the important tasks we are facing.
