ABSTRACT

In the past few years, with the breakthrough development of DNA sequencing technology, preimplantation genetic testing (PGT) has been widely used as an important part of assisted reproductive technology (ART). The progress of next generation sequencing (NGS) technology and the improvement of resolution, as well as the comprehensive application of molecular diagnostic technology makes it possible to perform the extensive and comprehensive chromosome screening and the clinical valuable detection of small gene fragment missing and repetition simultaneously, which is of great significance in terms of improving the pregnancy rate and reducing the abortion rate, multiplets rate and malformation rate. The common PGT molecular diagnostic techniques involves fluorescence in situ hybridization (FISH), single nucleotide polymorphism array(SNP-array), quantitative polymerase chain reaction(qPCR) and NGS. And each of them has its own highlights in clinical application and there are many uncertainties that are difficult to control. Moreover, ethical concerns brought about by technological progress also need to be addressed.

ABSTRACT

Different fragments of SARS-CoV-2 nucleocapsid (N) protein were expressed and purified, and a fluorescence immunochromatography method for detection of SARS-CoV-2 total antibody was established. The effect of different protein fragments on the performance of the method was evaluated. The N protein sequence was analyzed by bioinformatics technology, expressed in prokaryotic cell and purified by metal ion affinity chromatography column. Different N protein fragments were prepared for comparison. EDC reaction was used to label fluorescence microsphere on the synthesized antigen to construct sandwich fluorescence chromatography antibody detection assay, and the performance was systemically evaluated. Among the 4 prepared N protein fragments, the full-length N protein (N419) was selected as the optimized coating antigen, N412 with 0.5 mol/L NaCl was used as the optimal combination; deleting 91-120 amino acids from the N-terminal of N412 reduced non-specific signal by 87.5%. the linear range of detection was 0.312-80 U/L, the limit of detection was 0.165 U/L, and the accuracy was more than 95%. A fluorescence immunochromatographic detection method for analysis of SARS-CoV-2 total antibody was established by pairing N protein fragments. The detection result achieved 98% concordance with the commercially available Guangzhou Wanfu test strip, which is expected to be used as a supplementary approach for detection of SARS-CoV-2. The assay could also provide experimental reference for improving the performance of COVID-19 antibody detection reagents.

ABSTRACT

Objective:To investigate the efficacy of peritoneal perfusion combined with intravenous and oral chemotherapy in the treatment of gastric cancer with peritoneal metastasis and its correlation with prognosis.Methods:The clinical data of 142 patients with peritoneal metastasis of gastric cancer admitted to the Affiliated Hospital of Xuzhou Medical University from March 2012 to June 2019 were retrospectively analyzed.According to different treatment schemes, the patients were divided into observation group (47 cases treated with tegafur capsule orally+ docetaxel+ cisplatin combined with recombinant human tumor necrosis factor intraperitoneal perfusion) and control group (oral administration of tegafur capsule+ oxaliplatin). The clinical efficacy and prognostic factors were compared between the two groups.Results:The short-term efficacy after two courses of chemotherapy: the effective rate was 44.7% (21/47) in the observation group and 8.4% (8/95) in the control group, the difference was statistically significant (χ 2=25.438, P<0.001); the disease control rate was 97.9% (46/47) in the observation group and 60.0% (57/95) in the control group, the difference was statistically significant (χ 2=22.639, P<0.001). Long term efficacy: the progression free survival time of the observation group was higher than that of the control group (6.50 months vs.3.83 months, χ 2=16.399, P<0.001); the total survival time of the observation group was higher than that of the control group (15.60 months vs.10.83 months, χ 2=9.219, P=0.002). Univariate analysis showed that ascites volume, chemotherapy, palliative surgery, liver metastasis, Lauren classification and Her-2 expression were related to prognosis (all P<0.05); there was no significant difference in cumulative survival rate of different gender, age and ECOG score (all P>0.05). Multivariate analysis showed that liver metastasis ( HR=1.996, 95% CI=1.194-3.338, P=0.008 ), Lauren type ( HR=1.979, 95% CI=1.265-3.094, P=0.003 ), Her-2 expression ( HR=3.872, 95% CI=2.202-6.808, P<0.001 ), chemotherapy regimens(whether combined with intraperitoneal chemotherapy) ( HR=1.826, 95% CI=1.046-3.188, P=0.034 ) and abdomina volume ( HR=2.785, 95% CI=1.644-4.718, P<0.001 ) were independent risk factor for the prognosis of patients. Conclusion:Intraperitoneal perfusion combined with intravenous and oral administration has a good clinical effect in the treatment of peritoneal metastasis of gastric cancer, which can effectively improve the clinical symptoms and improve the survival rate of patients.The presence or absence of liver metastasis, Lauren classification, Her-2 expression, chemotherapy method (combined with intraperitoneal perfusion or not) and ascites volume are independent risk factors for the prognosis of peritoneal metastasis of gastric cancer.

ABSTRACT

Objectives To investigate the relationship between congenital nephrotic syndrome (CNS) and neonatal polycythemia, and clinical diagnosis and treatment. Methods The clinical manifestations, diagnosis, and treatment of a case of CNS with neonatal polycythemia were retrospective analyzed, and the related literature were reviewed. Results A male infant had abdominal distention after his birth, followed by feeding intolerance and poor response. On the third day of birth, he was diagnosed of neonatal polycythemia according to the levels of hemoglobin (249 g/L) and hematocrit (0.714 L/L). And after a partial exchange transfusion, the symptoms were improved. On the sixth day of birth, the infant had edema, urinary protein +++, serum albumin at 12.7 g/L and blood cholesterol at 8.84 mmol/L, and was clinical diagnosed of CNS. Oral hormone therapy was ineffective and he died 32 days after birth. Conclusions CNS combined with neonatal erythrocytosis is rare in clinic. The co-existing of the two is more likely to induce thromboembolism and organ dysfunction, and the clinical prognosis is poor.

ABSTRACT

Objective To investigate the significance of procalcitonin (PCT) and C-reactive protein (CRP) in the early diagnosis of sepsis in patients with percutaneous nephrolithotomy (PCNL). Methods One hundred and ninety-eight patients who had underwent PCNL were divided into sepsis group (148 cases) and control group (50 cases). The PCT and CRP 6 h before and after operation were compared between 2 groups, and the receiver operating characteristic curve was drawn. The area under curve (AUC), optimal diagnostic boundary value, susceptibility and specificity were calculated. Results The PCT and CRP before operation in sepsis group were significantly higher than those in control group:(3.911 ± 2.011) ng/L vs. (1.353 ± 0.311) ng/L and (54.85 ± 8.75) g/L vs. (38.65 ± 10.76) g/L, and there were statistical differences (P 1.65 ng/L, and the susceptibility and specificity were 97.91% and 91.01%; the optimal diagnostic boundary value of CRP was > 43.54 g/L, and the susceptibility and specificity group were 93.51% and 79.21%. Conclusions For patients with sepsis after PCNL, PCT is more significant than CRP for early diagnosis. PCT detection can be used as an important auxiliary examination for clinical diagnosis of sepsis, which could help clinicians to detect and treat the sepsis early and can greatly improve the survival rate of patients.

ABSTRACT

Objective To study the effects of Fructus ligustri lucidi and its monomers, tyrosol and oleanotic acid, on the migration of mouse melanoblast cell line (NCCmelb4M5). Methods Cultured NCCmelb4M5 cells were treated with Fructus ligustri lucidi (0.0625, 0.125, 0.25, 0.5, 2 mg/mL), tyrosol (0.02, 0.04, 0.08, 0.16, 0.8 mg/mL) and oleanolic acid (0.0625, 0.125, 0.25, 0.5, 2.5 mg/mL), respectively,for 48 hours followed by the detection of cell proliferation with MTT assay. The working concentration of the three drugs was determined according to the results of MTT assay. Scratch and transwell assays were performed to observe the effect of Fructus ligustri lucidi and its monomers at working concentration on the migration of NCCmelb4M5 cells. Results Based on the results of MTT assay, the working concentration of Fructus ligustri lucidi, tyrosol and oleanolic acid was determined at 0.125 mg/mL, 0.08 mg/mL and 0.0625 mg/mL respectively, and at these concentrations, these drugs exhibited a cytotoxity lower than that of absolute alcohol with no obvious stimulation of cell proliferation. Scratch and transwell assay revealed a promoting effect of both Fructus ligustri lucidi and tyrosol on melanoblast migration (P<0.05), while oleanolic acid had little effect on melanoblast migration. Conclusions The extract of Fructus ligustri lucidi has a significant stimulatory effect on the migration of mouse melanoblasts, and tyrosol may be an active component of Fructus ligustri lucidi associated with confirmative effect on migration of mouse melanoblasts.

ABSTRACT

Objective To observe the expression of TLR4 in hepatocellular carcinoma cell line HepG2 after transient and stable HBV genome transfection. Methods Immunofluorescence flow cytometry was used to detect mean fluorescence intensity (MFI) of TLR4 and TLR4 positive cell percentage in hepetocellular carcinoma cell lines HepG2 and HepG2. 2.15. Various doses of HBV DNA plasmid were transfected into HepG2 cells with lipefectamine 2000. Immunofluoroscenee flow cytometry was used to detect MFI of TLR4 and TLR4 positive ceil rate of infected HepG2 ceils. Trypan blue staining was used to examine the sum of living cells. Results MFI of TLR4 and TLR4 positive cell rate of HepG2.2.15 cells were significantly higher than those in HepG2 cells (both P' <0. Ol). MFI of TLR4 and TLR4 positive cell rate of HepG2 cells transfected by various doses of HBV DNA were significantly higher than those in control group (all P' < 0. 01). MFI of TLR4 and TLR4 positive cell rate of infected HepG2 cells were positively correlated with the doses of HBV DNA (both P' <0. 01) and negatively correlated with the sum of living cells (both P' <0. 01). Conclusions Enhanced expression of TLR4 appeared in HepG2 cells with both transient and stable HBV infection, along with reduction of living cells.

ABSTRACT

Objective To study the effect of matrine on the expression of a proliferation-inducing ligand (APRIL) in colorectal cancer cell line (SW480 cell). Methods MTT assay was used to evaluate the inhibitory effect of matrine on SW480 cells. The protein and mRNA levels of APRIL in SW480 cells were determined by immunohistochemistry and real-time fluorescence quantitative PCR (RFQ-PCR). SW480 cells were treated with 0.5,1.0,2.0 mg/ml of matrine for 24 h, 48 h and 72 h. FU and blank were served as drug control and blank control groups, respectively. Results Matrine had obviously inhibitory effect on proliferation of SW480 cells in a time- and dose-dependant manner. The expression of APRIL was strong in SW480 cells. When treated with 50,100,200 ug/ml of FU, the APRIL mRNA levels in SW480 cells raised gradually and reached the highest levels at 72 h after treatment, which were significantly higher than those in blank control group (all P value<0.001). When treated with 0. 5,1.0, 2.0 mg/ml of matrine, the APRIL mRNA levels in SW480 cells increased at 24 h after treatment, which were significantly higher than those in blank control group (all P value<0. 001), and then decreased gradually and almost equal to level of blank control group at 72 h. Conclusion In treatment with FU, the survival cells.may have stronger ability of proliferation due to higher expression of APRIL in SW480 cells. Anti-APRIL therapy might be an important assistant treatment to counter the impact of APRIL. Matrine will not cause persistent increase of APRIL mRNA levels in SW480 cells, so it might be a helpful drug in anti-tumor theraphy.

ABSTRACT

Objective To investigate the level of NF-E2 related factor 2 (Nrf 2) in vitiligo lesions.Methods Tissue samples were obtained by press suction blisters at lesional and donor sites of 12 patients with vitiligo who were managed with epidermal transplantation. Four lesional samples from the patients were subjected to primary culture and the level of Nrf 2 was detected by AEC immunohistochemistry after 48hours of culture. Western blotting was utilized to further detect the level of cytoplasmic and nuclear Nrf 2 in tissue samples from the other 8 patients with vitiligo. Results Immunohistochemistry revealed that Nrf 2 was predominantly expressed in cytoplasm, rather than nuclei, of keratinocytes in vitiligo lesions compared with the normal skin of patients. The level of nuclear Nrf 2 was significantly lower in lesions than that in normal skin (0.10 ± 0.03 vs 0.26 ± 0.03, P < 0.01) of the patients. In contrast, there was no significant dif- ference in the level of cytoplasmic Nrf2 between lesional and normal skin (0.61 ± 0.03 vs 0.60 ~ 0.02, P >0.05) of patients. Conclusion These results reveal an abnormality of nuclear translocation of Nrf 2 in vitili-go lesions.

ABSTRACT

BACKGROUND: The increase of leukocyte and blood glucose levels is a kind of stress reaction when acute cerebrovascular disease occurs, it often occurs at the early clinical stage of acute cerebrovascular disease.OBJECTIVE: To observe the levels of leukocyte and blood glucose at the early stage of acute cerebrovascular disease, and investigate their correlation with recent prognosis.DESIGN: A prognostic analysis based on diagnosis taken patients as observational subjects.SETTING: Qingtian County People's Hospital.PARTICIPANTS: Totally 235 inpatients with acute cerebrovascular disease aged (63.13±9.55) years were selected from Qingtian County People's Hospital between May 2000 and May 2002, including 90 cases of cerebral hemorrhage (52 males and 38 females) aged (63.13±9.55) years and 145 cases of cerebral infarction (73 males and 72 females) aged (71.22±8.00) years. The disease course ≤ 1 month. According to the number of leukocytes, the patients were divided into normal leukocyte group (n=167) and increased leukocyte group (n=68). According to the level of blood glucose, they were divided into normal blood glucose group (n=146) and hyperglycemia group (n=89). The neurologic deficit score (NDS) of 0-15 points was taken as mild, 16-30 as moderate and 31-45as severe.METHODS: All the patients received cranial CT examination immediately after admission, and fasting venous blood samples were drawn on the next morning to detect the levels of leukocyte and fasting blood glucose. The x2 test was applied.MAIN OUTCOME MEASURES: ① Comparison of age: It was obviously higher in the cerebral infarction group than in the cerebral hemorrhage group [(71.22±8.00), (63.13±9.55) years, t=6.90, P < 0.001]. ② Comparison of the percentage of disease types: In the increased leukocyte group,the percentage of cerebral hemorrhage was obviously higher than that of cerebral infarction (66%, 34%, x2=31.47, P < 0.005). In the hyperglycemia group, the percentage of cerebral hemorrhage was higher than that of cerebral infarction (51%, 49%, x2=9.12, P < 0.005). ③ Comparison of the percentage of severe neurological impairment: It was obviously higher in the increased leukocyte group than in the normal leukocyte group (26%, 6%,x2=21.12, P < 0.005), also markedly higher in the hyperglycemia group than in the normal blood glucose group (27%, 5%, x2=21.70, P < 0.005).④ Comparison of the percentage of death: It was obviously higher in the increased leukocyte group than in the normal leukocyte group (31%, 6%,x2=26.15, P < 0.005), also markedly higher in the hyperglycemia group than in the normal blood glucose group (26%, 5%, x2=20.02, P < 0.005). CONCLUSION: Both the increase of leukocyte and blood glucose can damage the brain tissue, and can be used to judge the disease condition of patients with acute cerebrovascular disease, estimate the prognosis and guide the treatment.

ABSTRACT

Objective To study the effects of several Chinese traditional medicines (CTM) on cell proliferation, cell toxicity, gene expression of Tyr and c-kit in normal melanocytes cultured from Caucasians. Methods The TRP and KIT protein expression was detected by Western blotting. The total soluble protein of melanocytes was measured by spectrophotometer by its absorption at 595nm against the standard concertration curre. Results Angelica dahurica, Fructus psoraleae, Spica Prunellae, Ligusticum chuanxiong Hort, and Eclipta Prostrasta stimulated the expression of KIT and the synthesis of total protein. The stimulating effect of Angelica dahurica and and Fructus psoraleae on the KIT expression was 69.44% and 58.43% respectively. However, these medicines only had a limited effect on the expression of Tyr in melanocytes. Conclusions The therapeutic effect of CTM on vitiligo may be related with the SCF/KIT pathway. This study might provide an useful way to screen more Chinese medicine for the treatment of vitiligo.
