There are few articles or reports collecting evidence about Kudiezi injection from premarketing and postmarketing research or studies systematically. This article is an exact miniature of a systematical report about Kudiezi injection. We analyzed information from four aspects, such as quality control reports, non-clinical premarketing safety experiments, postmarketing research (efficacy studies, hospital information system data and national spontaneous reporting system data), and literature analysis. All the four aspects build an evidence body for Kudiezi injection in order to inform its safety use in clinical practice and further study.

AIM: To investigate the changes of the L-type calcium channel subunit expression and calcium currents (I_~Ca -L) in cultured rat ventricular myocytes infected by coxsackie virus B_3 (CVB_3). METHODS: Primary cultured neonatal rat ventricular myocytes were infected with CVB_3. The changes of L-type calcium channel subunits mRNA in normal and infected myocytes were measured by semi-quantitative reverse transcription-polymerase chain reaction. I_~Ca -L was recorded in two groups respectively using whole cell patch-clamp techniques. RESULTS: The expression of ?_1 and ? subunits of L-type calcium channel mRNA increased in the infected group compared with the normal one (4.00?0.07 vs 2.21?0.41, P0.05). The average current density of I_~Ca -L significantly increased by CVB_3 infection [(-8.66?0.99) pA/pF vs (-6.97?1.75) pA/pF, P

Objective:To investigate the genetic etiology of a child with epilepsy accompanied by motor retardation.Methods:A patient with epilepsy and motor retardation in Henan Provincial People′s Hospital in January 2020 and his parents′ peripheral blood 2 mL were collected.G-banded karyotyping and array-based comparative genomic hybridization (aCGH) were used to analyze the duplication / deletion of chromosome segments in child and her pa-rents.Results:The karyotype of the patient revealed 46, XX, and add(19)(p13.3→qter), whereas aCGH detected a 9.50 Mb duplication at 19q13.33q13.43[arr(hg19)(49593920_59092570)×3]. This region contains 471 genes.No abnormality was discovered in the karyotyping and aCGH analysis of the patient′s parents.The phenotypes of the patient conformed to the previously reported clinical characteristics of 19q13.3 duplication.Conclusions:The de novo 19q13.3 duplication is the cause of epilepsy and motor development retardation for the patient.Combined with aCGH, the traditional G banding is valuable to diagnose the patient with developmental delay.

BACKGROUNDTransitional cell carcinoma of the upper urinary tract (UUT-TCC) accounts for 5% to 10% of all renal tumours and 5% to 6% of all urothelial tumours all over the world. In China, the proportion of UUT-TCC to all urothelial tumours may be 26%, which is higher than that in the western world. The early diagnosis of UUT-TCC is difficult and the present study elucidates the diagnostic value of poor or nonvisualization (PNV) in intravenous urography in patients with UUT-TCC and its correlations with pathological findings and clinical characteristics.

METHODSThe data of 172 consecutive patients between January 1997 and January 2005 with UUT-TCC who underwent nephroureterectomy in our departments were selected and analyzed retrospectively.

RESULTSOf our sample, 144 cases presented with gross haematuria (83.7%) and 12 with microscopic haematuria (7.0%). Forty-six cases (26.7%) were detectable by cytology. Filling defect identified 36 positive cases of 172 patients (20.9%), PNV was present in the images of 105 of 172 patients (61.0%). The detection rate by PNV (61.0%) was significantly different from that by cytology (26.7%) or by filling defect (20.9%) (P = 0.031, P = 0.001, respectively). Univariate logistic regression analysis for PNV showed that tumour stage, grade and size were significant predictors (P = 0.028; P = 0.031; P = 0.006, respectively). Tumour stage and size were identified as independent risk factors in the multivariate logistic regression model (P = 0.042; P = 0.014).

CONCLUSIONSExcept for suspected urolithiasis, urinary tuberculosis or congenital abnormalities, UUT-TCC should be considered if PNV exists in intravenous urography especially of old patients. The value of PNV is much more significant than filling defect in intravenous urography in the diagnosis of UUT-TCC. It is supposed that PNV carries more risk of higher stage and larger tumour size in UTT-TCC.

To investigate the effects of sorafenib and octreotide combination treatment on cellular proliferation and explore the underlying molecular mechanisms by using an in vitro cell culture system with the human hepatoma cell line, HepG2. HepG2 cells were treated with different concentrations of sorafenib and octreotide alone or in combination. Untreated HepG2 cells were used as controls. Treatment-induced cytotoxicity was determined with the cell counting kit-8 by Sigma-Aldrich, and rate of apoptosis was detected by flow cytometry. Fluorescent microscopy was used to observe rates of cell growth under the various treatments. Treatment-induced changes in protein expressions were detected by enzyme-linked immunosorbent assay (for vascular endothelial growth factor (VEGF)) and Western blotting (for the Mcl-1 apoptosis mediator and the ERK1/2 and PERK1/2 kinases). Sorafenib and octreotide, used alone or in combination, inhibited proliferation and induced apoptosis in HepG2 cells. Combination treatment was more effective than either mono-treatment (F = 200.398, P less than 0.05). Fluorescent microscopy showed that combination treatment stimulated phosphatidylserine, the marker of early apoptosis, better than either mono-treatment. VEGF expression in cultures exposed to combination treatment was also significantly lower than in mono-treatment or untreated control cultures (F = 1019.725, P less than 0.05). Western blotting showed that octreotide mono-treatment had no effect on Mcl-1 expression (vs. control group; P more than 0.05) and that combination treatment significantly lowered Mcl-1 expression (vs. mono-treatment and control groups; P less than 0.05). None of the treatments affected ERK1/2 expression (all, P more than 0.05), while all treatments significantly lowered PERK1/2 expression (vs. control group; F = 2.401, P less than 0.05) and the combination treatment lowered PERK1/2 significantly more than either mono-treatment (P less than 0.05). Sorafenib and octreotide can inhibit proliferation and induce apoptosis in the human hepatoma cell line, HepG2. Combination treatment is significantly more efficacious (P less than 0.05) and produced synergistic effects. The mechanism underlying this phenomenon may depend on synergistic inhibition of VEGF, the anti-apoptotic protein Mcl-1, and the proliferation-inducing PERK1/2.

OBJECTIVETo investigate the diagnosis and differential diagnosis of granulocytic sarcoma (GS).

METHODSThe morphological and immunological characteristics of 12 cases of GS were studied. FAB classification was made by peripheral blood, bone marrow picture and bone marrow biopsy assay.

RESULTSAll of the 12 cases presented with lymphadenopathy and soft tissue mass. Histologically, the tissue infiltration of GS was composed of blastic cells with round to oval nuclei showing an even, pale chromatin pattern. Some with cleaved or notched nuclei. There were prominent nucleoli and scant cytoplasm in the cells and mitosis was easily found. Immunohistochemically, CD(45) and lysozyme were positive in all of the cases, MPO in 11 (92%), CD(68) in 10 (83%), CD(34) in 5 (42%), and TdT in 2 cases (17%). CD(15) and Mac387 were mainly expressed in mature granulocytes. Examination of bone marrow sections and marrow aspirate smears showed that out of the 11 cases tested 8 were AML-M(2), 2 AML-M(1) and 1 AML-M(0). Only 1 case was nonleukemic, ie. solitary granulocytic sarcoma.

CONCLUSIONGranulocytic sarcomas are difficult to identify in routine paraffin-embedded tissue sections and usually misdiagnosed as non-Hodgkin's lymphomas. Immunohistochemistry study with a panel of antibodies in combination with bone marrow and peripheral blood examination are helpful in identification of granulocytic sarcoma.

OBJECTIVETo assess the association of polymorphisms of human leukocyte antigen DRB1 gene (HLA-DRB1) with susceptibility to unexplained recurrent spontaneous abortion (URSA).

METHODSThe HLA-DRB1 gene was typed with polymerase chain reaction-specific sequence primers (PCR-SSP) method in 200 couples with URSA and 200 couples with a normal pregnancy history.

RESULTSThe frequencies of DRB1*09 and DRB1*13 alleles were significantly greater in the URSA group compared with the control group (14.50% vs. 9.50%, and 7.00% vs. 4.38%, both P<0.05), whilst the frequencies of DRB1*04 and DRB1*12 alleles were significantly lower (7.13% vs. 10.75%, and 8.63% vs. 14.38%, both P<0.05). For females from the URSA group, the frequency of DRB1*09 allele (14.00%) was significantly higher compared with the controls (9.25%) (P=0.036), whilst the frequency of DRB1*12(8.50%) allele was significantly lower (14.00%) (P=0.014). For males in the URSA group, the frequencies of DRB1*09 and DRB1*13 alleles were significantly higher than those of the controls (15.00% vs. 9.75%, and 9.25% vs. 4.00%, both P<0.05), whilst the frequencies of DRB1*04 and DRB1*12 alleles were significantly lower (5.75% vs. 12.25%, and 8.75% vs. 14.75%, P<0.05).

CONCLUSIONThe DRB1*09 and DRB1*13 alleles may contribute to the susceptibility of URSA, while DRB1*04 and DRB1*12 alleles may confer a protective effect factors. For females, however, no significant association of DRB1*13 and DRB1*04 alleles with URSA was found.

OBJECTIVETo construct a recombinant bacillus Calmette-Guérin vaccine (rBCG) secreting human interferon-alpha 2b (IFN alpha-2b).

METHODSBCG Ag85B signal sequence and IFN alpha-2b gene were amplified from the genome of BCG and of human peripheral blood by polymerase chain reaction (PCR), respectively. IFN alpha-2b gene was cloned in E. coli-BCG shuttle-vector pMV261 to get pMV261-IFN alpha-2b. A new recombinant plasmid pMV261-IFN alpha-2b was constructed by inserting BCG Ag85B signal sequence into pMV261-Ag85B-IFN alpha-2b. Then, BCG was transformed with this recombinant plasmid by electroporation, and designated as rBCG-IFN alpha-2b. The DNA and protein expressions of IFN alpha-2b gene in rBCG were determined by PCR and Western blot respectively. Also the quantity of IFN alpha-2b protein secreted by rBCG in culture supernatants was determined by enzyme linked immunosorbent assay (ELISA).

RESULTSBy partial nucleotide sequencing, the DNA sequences of human IFN alpha-2b and BCG Ag85B were consistent with that in the Gene Bank, and were correctly inserted into the shuttle expression vector pMV261 to construct recombinant plasmid pMV261-Ag85B-IFN alpha-2b. BCG was successfully transformed with this recombinant plasmid by electroporation and the recombinant BCG (rBCG-IFN alpha-2b) was capable of synthesizing and secreting cytokine IFN alpha-2b. The concentration of IFN alpha-2b in culture supernatants was quantified by ELISA and calculated to be approximately 301.45 pg/ml.

CONCLUSIONSRecombinant BCG secreting human IFN alpha-2b (rBCG-IFN alpha-2b) was constructed successfully and the specific IFN alpha-2b protein can be expressed highly and steadily by rBCG vaccine.

OBJECTIVETo investigate the effect of small ubiquitin-like modifier (SUMO-1) modification on the formation of Lewy body like inclusions in cytoplasm and apoptosis of HEK293 cell induced by overexpression and mutation of alpha-synuclein.

METHODScDNA encoding the human alpha-synuclein without the stop codon was cloned into a pGEM T-easy vector. Restriction enzyme mapping and DNA sequencing were performed to analyze the plasmid, which was then subcloned into a pEGFP-N1 vector. The recombinant plasmid alpha-synuclein-pEGFP was transfected into HEK293 cells by lipofectamin method. Inclusions in the cultured cells were identified with HE staining. Apoptosis of the HEK293 cell was measured by Hoechst 33258 staining, MTT and Annexin V-PE flow cytometry.

RESULTSThe Lewy-body like inclusions were found in cytoplasm of cultured cells. Hoechst staining showed that the nuclei of cells were enlarged in the wild-type and A53T mutation groups 48 h after transfection, chromatin were accumulated and appeared spot-like. The nucleus stain was equitable in the K96R and K96R-A53T groups. MTT assay showed that the viability of cells transfected with empty plasmid was 96.2%, but it dropped to 53.4% and 56.1% in cells transfected with wild-type alpha-synuclein-pEGFP and A53T mutant group, respectively. The viability was 72.3% and 69.8% in cells transfected with K96R and K96R-A53T, respectively (P<0.05). Forty eight hours after transfection, the apoptosis rate was 3.9% in empty plasmid group, 32.2% and 34.1% in cells transfected with wild-type and mutant alpha-synuclein-pEGFP, 19.4% and 20.3% in the K96R and K96R-A53T transfected cells. There was significant difference between the two groups (P<0.05).

CONCLUSIONSUMO-1 modification did not have influence on the Lewy body-like inclusions formation in cytoplasm of HEK293 cell in vitro, but had a toxic effect which could increase the apoptosis induced by wild type overexpression and mutation of alpha-synuclein.
