AlM:To find better ways of treating ocular alkali burn, and to reduce the suffering of patients and social burden.METHODS:Totally 100 patients were graded according to the degree of chemical burns to four major groups, each half were randomly divided into the control group and the treatment group. Control group underwent conventional treatment. ln addition to conventional therapy, patients in each treatment group were also added a Breviscapine intravenous injection of 40mg daily. Corneal recovery time, changes in vision, degree of corneal opacity, number of corneal neovascularization and other complications were observed. Curative effects were analyzed statistically.
RESULTS:There was no significant difference in levelⅠgroup between control group and treatment group ( P>0. 05); There were significantly different in level Ⅱ, Ⅲand Ⅳ group ( P<0. 05 ). Compared to the degree of corneal opacity and the number of corneal neovascularization, the treatment group was obviously better than the control group(P<0. 05).
CONCLUSlON: Breviscapine in the treatment of ocular alkali burns can shorten the course of treatment, reduce corneal scarring, and improve vision.

ObjectiveTo investigate the D8/17 antigen expression of patients with rheumatic heart disease (RHD) in Guangdong province and study the antigen's characteristics.Methods The level of D8/17 antigen expression on B lymphocytes was determined with flow cytometry assay in 96 RHD patients and 83 unaffected controls.The percentage of B-cells expressing the D8/17 antigen having more than 10％ was considered to be positive. D8/17 antigen was extracted by immunopreeipitation,and the antigen characteristics was analyzed by tandem mass spectrometry. Results The mean percentage of B-cells expressing the D8/17 antigen was (85.36 ± 15.15)％ in the RHD patients and (82.89 ±4.55)％ in the controls,with no significant difference between the two groups ( P =0.436).Moreover,the positive rate of the D8/17 cxprcssion was 100％ in either the RHD patients or the controls.The molecular weight of D8/17 antigen was found to be 40 000-67 000,and the purified protein was most likely to match moesin or β-actin.ConclusionsB-cell antigen D8/17 is not associated with RHD in Guangdong province of China.Moesin or β-actin is the most likely protein to match D8/17 antigen.

OBJECTIVETo observe differences of therapeutic effects among acupuncture bloodletting, penicillin and acupuncture bloodletting combined with penicillin for children acute tonsillitis and providea better treatment method in cli nic.

METHODSSeventy-five mild cases were selected into section of mild symptoms while seventy-five severe cases were selected into section of severe symptoms. Cases in the two sections then were divided into, an acupuncture bloodletting group, a penicillin group and a comprehensive group by random digital table method separately, 25 cases in each one. Qu-chi (LI 11), Hegu (LI 4), Dazhui (GV 14), Shaoshang (LU 11) and Erjian (EX 11) were selected in the acupuncture bloodletting group, intravenous injection of penicillin sodium was applied in the penicillin group and acupuncture bloodletting combined with penicillin was applied in the comprehensive group. Efficacy assessment was conducted after 3 days in the section of mild symptoms and after 5 days in the section of severe symptoms.

RESULTSFor the section of mild symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group and 92.0% (23/25) in the acupuncture bloodletting group, which were both superior to 68. 0% (17/25) in the penicillin group (P<0.05), but no statistical significance was seen between the comprehensive group and acupuncture bloodletting group (P>0.05). For the section of severe symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group, which was obviously superior to 60.0% (15/25) in the acupuncture bloodletting group (P<0.01) and 68.0% (17/25) in the penicillin group (P<0. 05), and no statistical significance was seen between the acupuncture bloodletting group and penicillin group (P>0.05).

CONCLUSIONThe efficacy of acupuncture bloodletting combined with penicillin is little different from that of acupuncture bloodletting for treatment of children acute tonsillitis with mild accompanied symptoms, which were both superior to intravenous injection of penicillin sodium. For severe accompanied symptoms, the efficacy of acupuncture bloodletting combined with penicillin is obviously superior to acupuncture bloodletting and penicillin.

Objective To explore the dynamic spiral CT findings of adrenal ganglioneuromas and to evaluate its clinical value.Methods All 7 cases patients with adrenal ganglioneuromas confirmed by surgical pathology underwent spiral CT plain scanning and two phases dynamic enhancement scanning before operation.The CT images were reviewed and analysed retrospectively in comparison with surgical and pathological results.Results Six of 7 lesions were located in the right adrenal gland,1 in the left.The diameter of the tumors was 3.7—7.5cm,with a mean diameter of 4.6cm.The CT value of the plain scans, AP phases and PVP phases was 16.2—31.7 HU(with a mean value of 24.3 HU),20.9—36.6 HU(with a mean value of 30.2 HU),and 27.4—45.5 HU(with a mean value of 36.0 HU),respectively.The masses were well defined and showed a tendency of wedging into the space between the adjacent organs and structures and encasing the large vessels such as IV,but didn't compress or occlude them.Conclusion The dynamic SCT features of adrenal ganglioneuromas were obvious,dynamic SCT scans could suggest the diagnose.

OBJECTIVETo investigate the etiologic value of diarrheagenic E. coil harboring genomic O island 28(OI-28) containing five putative virulence genes (Z0608, Z0609, Z0615, Z0634 and Z0635), which were related to RTX (Repeat in toxin) toxin family isolated from children with diarrheal disease in Taiyuan.

METHODSIn the study, 257 fecal samples from children with diarrheal disease collected in Shanxi Children's Hospital. Diarrheagenic E. coli and enteropathogenic bacteria were isolated and identified by conventional bacterial culture and typing specific diarrheagenic E. coli (EPEC, EIEC, ETEC and EHEC) diagnostic serum, while diarrheagenic E. coli harboring genomic 01-28 containing five putative virulence genes (Z0608, Z0609, Z0615, Z0634 and Z0635) were detected by PCR and DNA southern blot hybridization.

RESULTS206 strains (80.16%) of enteropathogenic bacteria were detected from 257 children with diarrhea disease, containing 149 strains (57.98%) of diarrheagenic E. coli and 57 strains(22.18%) of other entero-pathogenic bacteria. Among 3 strains (2.01%) of EPEC, 2 strains (1.34%) of ETEC, 2 strains (1.34%) EHEC were detected by typing specific serum, while all of the 142 strains (95.30%) isolated were suspected to be diarrheagenic E. coli. 21 strains (14.09%) of diarrheagenic E. coil harboring genomic O1-28 containing five putative virulence genes (Z0608, Z0609, Z0615, Z0634 and Z0635) were detected by polymerase chain reaction and DNA southen blot hybridization, 8 strains (5.37%) of diarrheagenic E. coli containing only one genomic OI-28 virulence gene, 2 strains (1.34%) of diarrheagenic E. coli containing two genomic OI-28 virulence gene. 21 children with diarrhea diseases caused OI-28-harboring E. coli containing five important putative virulence genes were among 0 to 3 years old (80.95%). These children correlating with OI-28-harboring E. coli did not present special clinical symptoms or signs.

CONCLUSIONThe diarrheagenic E. coil harboring genomic OI-28 was one of the important etiology for children with diarrheal disease in summer season.

OBJECTIVETo evaluate the clinical significance of the application of fluorescence in situ hybridization (FISH) in detecting chronic myeloid leukemia (CML).

METHODSChromosome preparation was made by using 24-hour culture. FISH technique using dual color dual fusion (DC-DF) BCR/ABL probe was performed in all 158 cases and R-banding was also employed for karyotyping in some patients.

RESULTSAmong the 158 cases, 98 cases were Ph positive, of which 69 cases (70.4%) were typical FISH pattern (1R1G2F), the other 29 cases (29.6%) showed 12 different types of atypical FISH pattern. The most frequent atypical patterns found were 1R1G1F in 7 cases (7.1%), 2R1G1F in 5 cases (5.1%), 1R1G2F and 1R1G3F in 4 cases (4.1%), 2R2G1F in 3 cases (3.1%). Karyotype analysis on 18 CML cases with atypical FISH patterns demonstrated that the atypical FISH patterns were due to variant translocation in 3 cases; the additional third signal was because of a supernumerary Ph chromosome. The karyotyping results did not conform to FISH results in four cases suggesting the conceivable mistakes in karyotyping. The 1R1G1F signal pattern seen in 3 cases with classical t(9;22) resulted from the deletion of derivative chromosome 9. The 1R1G2F signal pattern detected in 40% to 64% of interphase cells of 3 cases without Ph chromosome by conventional cytogenetic analysis suggested a submicroscopic translocation. Three cases treated with Glivec or bone marrow transplantation showed normal karyotypes with a small amount of BCR/ABL positive cells by FISH detection.

CONCLUSIONFISH technique is of great value for the diagnosis of CML and confirmation of variant translocation, occult Ph translocation, derivative chromosome 9 deletion, therapeutic effect of interferon and Glivec as well as detection of minimal residual disease after bone marrow transplantation.

AIM: To identify the down-regulated genes in adult rat cardiac fibroblasts (CF) stimulated with angiotensin Ⅱ (AngⅡ). METHODS: Suppression subtractive hybridization (SSH) was performed between the CF stimulated by AngⅡ (driver) and unstimulated CF (tester) to generate subtractive cDNA library. The library was screened with dot blots hybridization to further verify the differentially expressed cDNA clones. Partial positive clones were sequenced and BLAST analyzed. RESULTS: Seventeen down-regulated genes related to intracellular signal transduction, transcriptional repression, deposition of fibrous matrix and cellular cytoskeletal rearrangement, and 4 new expression sequence tags (EST) were acquired. CONCLUSION: SSH is a powerful technique with high sensitivity for the detection and clone of down-regulated genes expressed in CF induced by AngⅡ, which is helpful to clarify the mechanism of cardiac remodeling.
