Objective To evaluate quantitatively the spasticity of elbow flexor biceps in stroke patients using integrated EMG (IEMG),and to correlate the IEMG with Ashworth scale.Methods The IEMG data was recorded from the biceps while passively stretch the elbow joint of a group of 90 subjects,and was correlated with the varying levels of Ashworth category(20 cases with grade 0,6 cases gradeⅠ,16 cases gradeⅠ~+,20 cases gradeⅡ,and 18 ca- ses gradeⅢ).Results The IEMG data were positively correlated with simultaneous Ashworth scale categories.The range of IEMG value corresponding to the Ashworth category is as follows:1.3～12.1 (6.7?5.4)?V?s vs Ash- worth grade 0;4.6～12.3 (8.5?3.9)?V?s vs Ashworth gradeⅠ.15.3～28.4(21.8?6.6)?V?s vs Ashworth gradeⅠ~+;37.2～68.9 (53.1?15.6)?V?s vs Ashworth gradeⅡ;82.3～144.1 (113.2?30.9)?V?s vs Ash- worth gradeⅢ.Conclusion The IEMG value can be used to quantify the spasticity of elbow flexor in stroke pa- tients.

OBJECTIVETo explore the correlation between Chinese medical (CM) syndrome types of chronic atrophic gastritis (CAG) patients and Helicobacter pylori (Hp) infection, polymorphisms of IL-1B, and IL-1β.

METHODSTotally 192 CAG patients and 202 healthy subjects (as the healthy control group) were recruited in this case-control study. The Hp infection was tested by 13C-urea breath test and colloidal gold-labeled assay (GICA). The concentration of peripheral blood IL-1β was measured by ELISA. The polymorphisms of IL-1B gene in the promoter region were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

RESULTSPi-Wei weakness syndrome (PWWS) was dominant in CAG patients (31.77%, 61/192 cases). The Hp infection ratio in CAG patients was 53.65% (103/192 cases), of which, Pi-Wei damp-heat syndrome(PWDHS, 64.86%, 24/37 cases) and Gan-Wei disharmony syndrome (GWDS, 66.67%, 24/36 cases) were dominant. Compared with the health control group, the plasma concentration of IL-1β was obviously elevated in CAG patients with PWDHS, GWDS, and static blood obstructing collaterals syndrome (SBOCS) (all P < 0.05). Additionally, there was no difference in the distribution of polymorphisms in the promoter region of IL-1 B gene between the CAG patients and the healthy control group (P > 0.05).

CONCLUSIONSThe incidence risk of CAG was not associated with IL-1B polymorphism. But CM syndrome types of CAG patients was associated with Hp infection and peripheral blood IL-1β levels.

Objective To study correlation between MRI signal intensity of the lumbar intervertebral disc and collagen content in the nucleus pulposus.Methods Thirty-one cases with lumbar intervertebral disc herniation(male 21,female 10)received percutaneous lumbar disketetomy.Thirty-one specimens of nucleous pulposus were obtained from percutaneous lumbar disketctomy procedure and collagen content in them was measured with reformed hydroxyproline measurement method.The signal intensity(SI) of lumbar intervertebral disc and cerebrospinal fluid was measured in T_2 WI sagittal image and then ratio of disc SI to cerebrospinal fluid SI was calculated.The Pearson analysis was used to analyze the correlation between the collagen content and SI ratio and disc SI on T_2 WI.Results Collagen content and SI ratio were (231.0?63.5)mg/g and 0.19?0.07,respectively.There was negative correlation between them (r=-0.61,P

Objective To determine the influence of protein fusion on the biological characteris- tics of hymidine kinase(TK)and human immunodeficiency virus(HIV)Tat recombinant protein. Methods By utilizing polymerase chain reaction(PCR)technique,different fragments containing two,four or six glycines(Gly)were inserted between the HIV Tat gene and TK,and cloned into PBK vector.After testified by sequencing,the vectors were transfected into E coli.After induced by iso- propyl thiogalactose(IPTG),bacilli were collected and destructed by ultrasonic,the fusion proteins were determined by monoclonal antibody against HIV protein.HepG2 cells were incubated in DMEM supplement with 10?g/mL HIV-Gly(n)-TK(n=0,2,4,6)fusion protein,TK-HIV Tat and only HIV Tat.HepG2 cells in different groups were detected by immunofluorescence assay 24 hours after transduction with HIV Tat monoclonal antibody.The rate of apoptosis after cells were incubated with gencilovir(10?g/mL)for 3 days was determined by cell flow cytometry,while survival cell ratio was recorded by trypan blue.The data were analyzed by statistics(t-test).Results The Tat-Gly(n)-TK (n= 0,2,4,6)recombinant genes were constructed and inserted into PBK vectors,which were expressed in E coli and then purified.Cells in different groups,which were incubated with Tat-Gly (n)-TK(n=0,2,4,6)fusion proteins,Tat-TK fusion protein,TK-Tat fusion proteins or only Tat proteins respectively,were detected by immunofluorescence assay.The intensities of fluorescence in different groups were almost same,but the ratios of cell survival or apoptosis were different.The highest ratio of cells apoptosis(14.77%)was in the group that cellular culture medium was mixed with Tat-Gly(4)-TK fusion protein,followed by the groups containing 6,2 glycines or no TK gene in genes(4.30%,12.69% and 1.03%,respectively).There were significant differences between each 2 groups among the all groups(t-test,P

Objective To explore the causes and treatment of repeated vulvovaginitis in girlhood in order to improve its prevention and treatment.Methods Fifty-one girls with repeated vulvovaginitis(age≤10 years)admitted to The Second Affiliated Hospital of Sun Yat-sen University from Jan.1990 to Nov.2004 were reviewed retrospectively.Results We found 28 girls(55%)suffering from non-specific vulvovaginitis and 14 ones(27%)suffering from posterior recto-vaginal fistula with in 51 patients.Five girls(10%)were smitten with vulval ulcer and 3 ones(6%)had been were found with vaginal foreign bodies.One girl(2%) was smitten with adhesion of labia minora.The vaginal discharges taken from 21 girls were cultured. Seventeen cases found bacteria.The positive rate of bacteria culture in the 21 cases reached 81%,in which, E.coli accounted for 5 cases(24%),staphylococcus and streptococcus accounted for 3 cases(14%) respectively.Patients suffered from non-specific vulvovaginitis and vulval ulcer accepted external lotion, antibiotic ointment or combining with antibiotics.Patients suffered from posterior recto-vaginal fistula accepted fistulectomy.Three girls who found vaginal foreign bodies took out of foreign bodies by hysteroscopo.Fifty-one girls all were cured after appropriate therapy.Conclusions Vulvovaginitis is the most common gynecologic diagnosis in girlhood.The principal cause of repeated invasion is non-specific vulvovaginitis and the secondly one is posterior recto-vaginal fistula.It need overhaul during the diagnosis.It is very availability to use hysteroscopy and do bacteria culture+antibiotic sensitivity test for repeated pediatric vulvovaginitis.

Objective To study the effects of salt sensitivity on evolution of blood pressure and develope- ment to hypertension from adolescents to youth.Methods A baseline survey was carried out in 4623 adolescents aged 6-15 years old in Hanzhong rural area in 1987,310 of them were recruited for determination of salt sensitiv- ity using the tests of oral saline load and furosemide sodium-volume depletion.Salt sensitivity (SS) were diag- nosed in 101 while 209 subjects as no-sah sensitivity (NSS).This cohort of adolescents were followed up for av- erage 18 years.Results The response rate for this cohort of adolescents was 71.9%.At the end of follow up period,BP in subjects with baseline SS was higher in youth than that in NSS (SBP:122.9?13.1 vs 117.3?12.4, P

Objective:To investigate the relationship between clinical effects of acupuncture for elderly patients with sensorineural deafness and ear distending sensation.Methods:A total of 120 elderly patients with sensorineural deafness were randomly divided into a comprehensive treatment group,an acupuncture group and a Western medicine group,with 40 cases in each group.The acupuncture group received acupuncture treatment,the Western medicine group received oral mecobalamin tablets and the comprehensive treatment group received acupuncture plus acupoint injection and auricular acupoint sticking.The values of pure tone hearing threshold test of the three groups were observed before and after treatment,and the relationship between clinical effects and ear distending sensation was compared.Results:The total effective rate of the comprehensive treatment group was 82.5％ versus 67.0％ in the acupuncture group and 62.5％ in the Western medicine group.The inter-group comparisons showed statistically significant differences in the comprehensive treatment group versus the Western medicine group (P＜0.01) and the acupuncture group (P＜0.05).In the comprehensive treatment group,there were 23 cases (57.5％) with ear distending sensation,the clinical total effective rate was 86.9％;there were 17 cases (42.5％) without the sensation,the clinical total effective rate was 76.5％.In the acupuncture group,there were 24 cases (60.0％) with ear distending sensation,the clinical total effective rate was 71.0％;there were 16 cases (40.0％) without the sensation,the clinical total effective rate was 63.0％.In the Western medicine group,there were 21 cases (52.5％) with ear distending sensation,the clinical total effective rate was 66.7％;there were 19 cases (47.5％) without the sensation,the clinical total effective rate was 57.9％.The total effective rate of patients with ear distending sensation were higher than the rates of those without ear distending sensation in the three groups,but the differences were insignificant (all P＞0.05).Conclusion:The comprehensive therapy is one of the effective methods to treat elderly patients with sensorineural deafness.In the three groups of elderly patients with sensorineural deafness,the relief of ear distending sensation and the hearing loss were basically simultaneous,and the hearing recovery in the patients with ear distending sensation may be slightly better than that in those without ear distending sensation.Nevertheless,further research is needed.
