We performed a retrospective analysis of the results of surgical treatment of sixteen patient with comminuted fracture of the distal femur from September 1993 to August 1995 and evaluated the efficacy of the angled blade plate as one of the fixation devices used. The fractures were limited to C2 and C3 fracture classifed according to the AO classification. After an average follow-up of 13 months (range, 9 to 24 months), all of the fractures had healed. Postoperatively, the arc of flexion was limited between 90degrees and 125degrees in eight, normal arc in five, and severely restricted arc of joint motion was present unexceptionally in three patients with deep infection. In angular deformity, average 5.8degrees of valgus and 2.4degrees posterior angulation were showed. The functional results by Sanders-Swiontkowski-Rosen-Helfet rating system were showed excellent in 3, good in 7, fair in 3, and poor in 3 cases. The overall results were seen to be excellent to good in ten cases (62.5%) but in twelve patients using the angled blade plate, excellent to good results were showed 10 patients (83.3%). We attribute the favorable results in our series to restoration of the articular surface through the modified extensile approach, sufficient stable fixation using the angled blade plate with conforming to the concept of bridge plate, routinely performing the bone graft for medial buttress and bone healing, and early mobilization of the extremity.

Estrogen receptors (ERs) are members of nuclear receptors and related to several diseases such as cancer, inflammation and osteoporosis. ERs have two forms, ERα and ERβ, which have different functions and organism distributions. Compounds selectively targeting ERβ can regulate important physiological functions and avoid the side effects caused by targeting ERα. Therefore, selective ERβ ligands have received considerable research interest in recent years. In this article, different kinds of selective ERβ ligands were summarized and their structure-activity relationships were also analyzed.

OBJECTIVETo investigate the feasibility and clinical application value of selecting viable spermatozoa by noncontact diode laser.

METHODSWe obtained immotile spermatozoa from 2 infertile men with obstructive azoospermia or severe asthenospermia and selected viable spermatozoa using a single laser shot at the sperm tail. Those that responded to the laser shot by a curling reaction of the tail were regarded as presumably viable and used for intracytoplasmic sperm injection (ICSI).

RESULTSThe mean fertilization rate was 88.89% after ICSI with the laser-selected viable spermatozoa. Both of the embryo transfers resulted in a single pregnancy.

CONCLUSIONNoncontact diode laser is a useful alternative for the assessment of sperm viability, which may help to achieve successful pregnancy.

Determination of the immunoglobulin M(IgM) in umbilical cord sera has been advocated as a screening test for intrauterine infection, since the IgM is produced by the fetus and is not transported across the placenta from mother. The low level of IgM in normal neonate is thought to reflect the infrequent encounter of antigenic stimuli by the futus, upon exposure to an appropriate antigen, however, the fetus is capable of increased IgM production, as has been doucumented in infant with rubella syndrome, cytomegalic inclusion disease, toxoplasmosis and syphilis. But until now we don't have the normal value of cord serum IgM in Korean neonate yet. So we performed the study to determine the normal value of serum IgM in Korean neonate and further more we try to compare the value of other condition such as congenital syphilis, maternal infection during pregnancy other than syphilis and congenital anomalies. Results were as followes: 1. Normal value of cord Igm was 11.83+/-9.92 mg % 2. There was no sexual difference 3. Lowest levele were noted at small weight(2500 gm upwards arrow) and short gestation period(28 wk upwards arrow) but not significant thereafter 4. There was no difference by matenal age and socioeconomic status 5. In congenital syphilis there was significant increment of cord IgM compared with normal group 6. There was no significant increment of cord ISM in cogenital anomalies 7. After 6 months, IgM levels were increased to adult level.

OBJECTIVETo evaluate the molecular mechanism and prognostication of bcl-2 protein expression in different subgroups of diffuse large B-cell lymphoma(DLBCL) in Guangxi Zhuang Autonomous Region, China.

METHODSImmunohistochemical stains for CD10, bcl-6, MUM-1, bcl-2 and NF-κB were performed in 214 cases of DLBCL. The Hans immunologic classification was applied to classify DLBCL into GCB and non-GCB subgroups. Using a dual-probe fluorescence in-situ hybridization (FISH) assay, IgH/bcl-2 gene translocation and bcl-2 amplification were analyzed.

RESULTSIn 214 cases of DLBCL, 30.8% (66/214) of cases were GCB and 69.2% (148/214) were non-GCB. Twenty-seven point three percent (18/66) of GCB subgroups and 59.5% (88/148) of non-GCB subgroups had bcl-2 protein expression, with a significant difference (P < 0.01). IgH/bcl-2 translocation was positive in 3.7% (8/214) of cases, even majority of them (6/8) was found in GCB subgroup, while represented only 9.1% of GCB case. There was a significant difference (P = 0.02) in bcl-2 gene amplification between GCB (27/66, 40.9%) and non-GCB subgroup (86/148, 58.1%). Among non-GCB cases, the expression of bcl-2 was correlated with that of NF-κB expression and bcl-2 gene amplification (r = 0.216 and 0.219, respectively, P < 0.05). No similar correlation was observed in GCB cases. The overall survival time of bcl-2-positive patients (31.4 ± 3.8) months was shorter than that of bcl-2-negative patients (40.2 ± 4.2) months. In conjunction with immunophenotypes and clinical stages, the bcl-2 positive patients had a 1.89 times higher risk than that of the bcl-2 negative patients.

CONCLUSIONSMajority of the cases were prognostically unfavorable non-GCB subgroups among DLBCL, which were characterized by high frequency of bcl-2 gene amplification and low frequency of IgH/bcl-2 translocation. The anti-apoptotic gene bcl-2 was frequently expressed in non-GCB subgroups and closely related to the gene amplification and NF-κB activation. bcl-2 positive patients had more short overall survival times, would face significant higher risk of death, these results suggested that bcl-2 could be a prognostic marker independent to clinical staging and immunophenotyping.

OBJECTIVETo study the effects of kaixinsan on behavior and expression of p-CREB in hippocampus of the chronic stress rats.

METHODThe male Wistar rats which gained the similar scores by Open-field test were selected, then the depression model rat was produced by separation and chronic unpredictable mild stress. Open-field test was performed to detect the behavior of rats and immunohistochemistry was used to observe the changes of p-CREB expression in hippocampus.

RESULTOn the 22nd day, the body weight and sacchar-intake of the depression model rats were all lower than those of the normal rats and the body weight and sacchar-intake of the rats treated by drugs were higher compared with model rats (P < 0.01). The depressive behavior in kaixinsan 4 g x kg(-1) group was significantly improved compared with the model group, the crossing scores and rearing scores were all increased (P < 0.01) and the expression of p-CREB in CA1, CA3 and DG in hippocampus was higher than that in the model group (P < 0.05 and P < 0.01).

CONCLUSIONKaixinsan might improve depressive behavior by increasing expression of p-CREB in CA1, CA3 and DG in hippocampus of the chronic stress rats.

This study is to elucidate the metabolic pathway of 1,2-[bis (1,2-benzisoselenazolone-3 (2H)-ketone)]-ethane (BBSKE) in rats. Rats were administrated with a single dose of BBSKE 200 mg x kg(-1). The metabolites in rat urine, feces, bile and plasma were identified by LC-MSn analysis. The characterization of fragment ions from LC-MSn chromatography and mass spectrometry was applied to the investigation of structures of metabolites. Three phase I metabolites were detected in rat urine and feces. Two of them were also found in plasma and one existed in bile. These products were derived from oxidized, methylated and S-methylated BBSKE, separately. One phase II glucuronide of BBSKE was also found in bile. Therefore, it is possible that BBSKE was metabolized by oxidization, methylation and glucuronidation.

OBJECTIVEFor anti-inflammation, relieving pain and decreasing acute toxicity, the best condition for extracting procedure of Psammosilene tunicoides was chosen. And the relationships between several solvent extracts and pharmacodynamic index were studied.

METHODUniform design with multi-targets was used in the optimization process, and the evaluate index were the results of anti-inflammation, relieving pain and LD50 were employed as the evaluating indexes. At the same time, the contents of the extracts, water extract, acetic ester extract and ether extract were determined.

RESULTThe best condition is that the medicinal material is optimized with 8 times of water (pH 6-7) and 2 h of each time. The best condition is satisfactory by test verification. And the pharmacodynamic actions of anti-inflammation, relieving pain and LD, were not obviously related to the dry extracts, water extract, acetic ester extract and ether extract.

CONCLUSIONUniform design method with pharmacodynamic index has the merit of being relaated to the function and symptom directly. The extracted twice technology condition optimized is stable, feasible and suitable for industry production. And it is not suitable to take the solvent extracts as quality control index related to the function and symptom.

OBJECTIVETo evaluate the prevalence of FLT3 gene expression and internal tandem duplication (ITD) mutation in acute myeloid leukemia (AML) patients and its clinical significance.

METHODSThe expression level of FLT3 mRNA was detected with real-time quantitative RT-PCR (RQ-PCR) technique in 152 bone marrow samples from 129 AML patients. The ITD of the FLT3 gene (FLT3/ITD) was detected in 75 de novo AML patients by reverse transcription polymerase chain reaction (RT-PCR).

RESULTSThe expression levels of FLT3 mRNA was 0.0020(0.0006 - 0.0040) in normal controls, and 0.1041 (0 - 33.8736) in 80 de novo AML patients (P = 0.001). FLT3/ITDs were found in 11 (14.7%) of 75 de novo AML patients. The FLT3 expression levels in patients with FLT3/ITD were 0.0297 to 33.8736 with a median level of 0.2200, and in those without FLT3/ITD were 0 to 26.2200 with a median level of 0.0975. The FLT3 expression levels in the former patients were higher than that in the latter ones, but there was no statistical significance (P = 0.093). The complete remission (CR) rate was lower in acute promyelocytic leukemia (APL) patients with FLT3/ITD than in APL patients without FLT3/ITD (P = 0.015). In de novo AML other than APL patients without FLT3/ITD, the CR rate was lower in patients with higher levels of FLT3 expression (expression level > 0.04, CR rate 37.5%) than those with lower levels of FLT3 expression (expression level < 0.04, CR rate 100%). On follow-up of 20 patients, the FLT3 expression level was decreased at least one logarithm degree when they got CR, but it was no significant change in non-remission patients.

CONCLUSIONSQuantification of FLT3 mRNA expression level and detection of FLT3/ITD in AML patients may serve as an index for evaluating therapeutic efficacy, predicting prognosis, and monitoring minimal residual disease.

OBJECTIVETo investigate the gene mutations of ADAMTS13 in a highly suspected hereditary thrombocytopenic purpura (TTP) patient, and then make a progressive diagnosis and adjust the plan of therapy.

METHODSADAMTS13 activity and inhibitor were determined by residual-collagen binding assay during several episodes. Genomic DNA extracted from the proband's peripheral blood was used for amplification of 29 exons and exon/intron boundaries of ADAMTS13 by PCR. The PCR products were screened by direct sequencing and the gene alterations were further confirmed by direct sequencing in her family members.

RESULTThe activity of the proband's ADAMTS13 was significantly reduced while no inhibitor was found. Two novel missense mutations were found in the TSPI repeated motif domain of ADAMTS13. In both mutations, thymine substituted for cytidine, resulting in the substitution of leucine for serine in nt 2708, exon 21 (codon S903L), and tryptophan for arginine in nt 3283, exon 25(codon R1095W). These two mutations were revealed as each heterozygote in the proband's parents.

CONCLUSIONThe deficiency of ADAMTS13 caused by two homozygote missense mutations might be responsible for episode of this TTP patient.
