ABSTRACT

OBJECTIVE@#To screen for mutations of fragile X mental retardation 1 (FMR1) gene during early and middle pregnancy and provide prenatal diagnosis for those carrying high-risk CGG trinucleotide expansions.@*METHODS@#Peripheral blood samples of 2316 pregnant women at 12 to 21(+6) gestational weeks were collected for the extraction of genomic DNA. CGG repeats of the FMR1 gene were detected by fluorescence PCR and capillary electrophoresis. Genetic counseling and prenatal diagnosis were provided for 3 women carrying the premutations.@*RESULTS@#The carrier rate of CGG repeats of the FMR1 gene was 1 in 178 for the intermediate type and 1 in 772 for the premutation types. The highest frequency allele of CGG was 29 repeats, which accounted for 49.29%, followed by 30 repeats (28.56%) and 36 repeats (8.83%). In case 1, the fetus had a karyotype of 45,X, in addition with premutation type of CGG expansion of the FMR1 gene. Following genetic counseling, the couple chose to terminate the pregnancy through induced labor. The numbers of CGG repeats were respectively 70/- and 29/30 for the husband and wife. In case 2, amniocentesis was performed at 20 weeks of gestation. The number of CGG repeats of the FMR1 gene was 29/-. No abnormality was found in the fetal karyotype and chromosomal copy number variations. The couple chose to continue with the pregnancy. Case 3 refused prenatal diagnosis after genetic counseling and gave birth to a girl at full term, who had a birth weight of 2440 g and no obvious abnormality found during follow-up.@*CONCLUSION@#Pregnant women should be screened for FMR1 gene mutations during early and middle pregnancy, and those with high-risk CGG expansions should undergo prenatal diagnosis, genetic counseling and family study.

ABSTRACT

Objective The purpose of this study was to investigate the differential expression of microRNA in gefitinib acquired resistant lung cancer cells and non-resistant cells and their roles on cell growth.MethodsGefitinib resistant NSCLC A549 and H1299 cells were constructed. The cell activity was detected by CCK-8 assays. Real-time PCR was used to detect microRNA expression. The intracellular microRNA expression profile was detected by microarray. The transfection of miRNA-7 mimic was used to up-regulate the expression of mir-7. EGFR protein expression was detected by Western -blotting.ResultsThe IC50 value of gefitinib resistant cells was 3 fold than that of their parental cells. The drug-resistant cells grew slowly compared with their parental cells. 43 miRNA were significantly changed in the gefitinib resistant cells, including 25 up-regulated miRNA and 18 down-regulated miRNA. The IC50 was significantly decreased and the EGFR expression was negatively regulated after up-regulated of mir-7.ConclusionmiR-7 expression negatively regulates EGFR expression and decreased expression of miR-7 is one of the mechanisms leading to gefitinib resistance in non-small cell lung cancer cells.

ABSTRACT

Regulatory T cell (Treg) is a subset of T cells that negatively regulates immunity and has the function of inhibiting rejection. The specific modification of Treg by chimeric antigen receptor (CAR) technology can successfully chime donor-specific antigen onto the surface of Treg, thus regulating the immune function of the body in a real-time manner. It provides a novel and promising therapeutic option for inducing immune tolerance. In this article, research progresses on Treg in immune related diseases, main difficulties in the realization of CAR-Treg technology and its role in inducing transplantation immune tolerance were reviewed, and the opportunities and challenges of CAR-Treg application in the field of organ transplantation are prospected.

ABSTRACT

Objective To observe the influence of dexmedetomidine applied in combined acupuncture-medication anesthesia on vomiting after thyroidectomy. Method Seventy patients who were going to receive thyroidectomy were randomized into group A and B, with 35 cases in each group. Combined acupuncture-medication anesthesia [electroacupuncture at Hegu (LI4), Neiguan (PC6) and Futu (ST32) plus intravenous infusions of sufentanil citrate injection (0.3 mg/kg) 20 minutes before operation]was adopted in both groups. Group A was additionally intervened by constantvelocity micropump infusion of dexmedetomidine hydrochloride injection (0.5 mg/kg) within 10 minutes before operation and remaining 0.4 mg/kg/min during operation, while group B was intervened by infusion of normal saline 10 minutes before operation. The observer's assessment of awareness/sedation (OAA/S) scores at different time points[lying in bed for 5 minutes before operation (T0), before the beginning of the operation (T1), 30 minutes after operation (T2), 60 minutes after operation (T3) and at the end of operation (T4)] in the two groups were observed. The additional times and total dose of sufentanil during operation, the number of cases using esmolol and urapidil, and the number of vomiting cases occurred within 2 hours after operation and 2~24 hours after operation in the two groups were recorded.Result The additional times and total dose of sufentanil during operation in group A were significantly different from those in group B (P<0.01). The utilization rate of esmolol and urapidil were respectively 31.4% and 14.3% in group A versus 77.1% and 65.7% in group B, and the between-group differences were statistically significant (P<0.01). The incidence of vomiting within 2 hours after operation and 2~24 hours after operation were respectively 20.0% and 17.1%in group A versus 54.3% and 42.9% in group B, and the between-group differences were statistically significant (P<0.01). The OAA/S scores at different time points (T1, T2, T3 and T4) in group A were significantly different from those in group B (P<0.01). Conclusion Dexmedetomidine applied in combined acupuncture-medication anesthesia can reduce the additional times and total dose of sufentanil during thyroidectomy, and it can reduce the incidence of postoperative vomiting as well.

ABSTRACT

OBJECTIVE@#To detect potential mutations of the PKHD1 gene in two pedigrees affected with infantile polycystic kidney disease.@*METHODS@#Clinical data and peripheral venous blood samples were collected from the probands and their parents as well as fetal amniotic fluid cells. Genome DNA was extracted from the peripheral blood samples and amniotic fluid cells. Exons 32 and 61 of the PKHD1 gene were amplified with PCR and subjected to direct sequencing.@*RESULTS@#The proband of pedigree 1 was found to carry c.4274T>G (p.Leu1425Arg) mutation in exon 32 and c.10445G>C (p.Arg3482Pro) mutation in exon 61 of the PKHD1 gene, which were inherited from her father and mother, respectively. The fetus has carried the c.4274T>G (p.Leu1425Arg) mutation. In pedigree 2, the wife and her husband had respectively carried a heterozygous c.5979_5981delTGG mutation and a c.9455delA mutation of the PKHD1 gene. No chromosomal aberration was found in the umbilical blood sample, but the genetic testing of their fetus was failed. Based on software prediction, all of the 4 mutations were predicted to be pathogenic.@*CONCLUSION@#PKHD1 c.4274T>G (p.Leu1425Arg), c.10445G>C (p.Arg3482Pro), c.5979_5981delTGG and c.9455delA were likely to be pathogenic mutations. The results have facilitated genetic counseling and prenatal diagnosis for the two pedigrees.

ABSTRACT

OBJECTIVE@#To analyze the hematological characteristics of HbE homozygotes.@*METHODS@#Complete blood cells count and hemoglobin electrophoresis were used for phenotypic analysis of 78 cases with HbE homozygotes from Yunnan province, China. The PCR-fluorescence hybridization was used to detect the common gene mutation of thalassemia. The hematological indexes, including MCV, MCH, Hb, HbA2, HbF and HbE were statistically analyzed between groups with different sex, ages and compound α thalassemia status.@*RESULTS@#In HbE homozygotes (HbEE), 89.5% (17/19) children presented mild to moderate microcytic hypochromic anemia, and 10.5% of them presented moderate anemia. 39.6% (19/48) of women with HbEE developed mild anemia ,while 11 cases of male with HbE homozygotes were asymptomatic. The levels of MCV and MCH in HbE homozygotes increased by co-inheritance of α thalassemia mutation.@*CONCLUSION@#The clinical phenotype of HbE homozygote shows highly heterogeneous, which is relates with age, sex and co-inheriting α-globin genotypes. In Hb EE women and children are more likely to develop mild to moderate anemia. The microcytic hypochromic anemia degree is relieved when HbEE combined with α- thalassemia.

ABSTRACT

Schistosomiasis was once heavily endemic in Jiangsu Province. Following the control efforts for several decades, schistosomiasis was almost eradicated in all endemic counties in Jiangsu Province in 1980, and transmission control was achieved in the province in 2011. According to the principle of “implementing the control measures with adaptation to local circumstances and guiding the control programs with classified interventions”, an integrated strategy with emphasis on the management of both infectious sources and snails has been recently employed for schitsosomiasis control in Jiangsu Province. In addition, a sensitive and highly effective surveillance system has been built and the application of novel techniques and information construction has been intensified to effectively interrupt the transmission of schistosomiasis in the Province. Transmission interruption of schistosomiasis was achieved in all endemic counties in Jiangsu Province. The paper summarizes the endemic situation of schistosomiasis, progress of schistosomiasis control, and major schistosomiasis control measures implemented during the stage of transmission interruption in Jiangsu Province.

ABSTRACT

Objective To explore the antiviral effect and mechanism of interferon-α (IFN-α) in chronic HBV infection mouse model by hydrodynamic tail vein injection. Methods Chronic HBV infection mouse model was constructed with C57BL/6j mice by hydrodynamic tail vein injection of pAAV-HBV1.2 plasmid. Serum IFN-α was determined by ELISA after injection of IFNα- expressing plasmid (i.e., plasmid pKCMvint.IFN-α-2a) or control plasmid pKCMvint. HBsAg and HBeAg levels were assayed on Abbot ARCHITECT i2000SR. Total lymphocytes in liver or spleen were counted and the frequency and function of CD8+T cells and HBV-specific CD8+T cells were analyzed by flow cytometry. Results Serum IFN-α expression level was significantly higher in the animals injected with pKCMvint.IFN-α-2a plasmid than in control group (P<0.01). Serum HBsAg decreased quickly 12 days after injection and significantly lower than control group. Serum HBeAg was undetectable after IFN-α expression. Interestingly, the frequency of CD8+T cells in the liver of animals injected with pKCMvint.IFN-α-2a plasmid was significant higher than control group (P<0.05), while total liver lymphocytes and HBV-specific CD8+T cells had a similar trend. Consistently, the HBV-specific CD8+T cells in IFN-α-expressing animals showed higher level of producing IFN-γ, TNF-α and IL-2 than control group. IFN-γ production was significantly different between IFN-α- expressing group and control group (P<0.05). Conclusions IFN-α can increase the frequency and function of liver CD8+T cells to inhibit HBV gene expression in chronic HBV infection mouse model.

ABSTRACT

Objective: To evaluate the influence of the rough surface of dental implants prepared by selective laser melting (SLM) on early bone healing around titanium implants. Methods: A total of sixteen titanium implants were involved in our research,of which eight implants were prepared by SLM (TIXOS (R) Cylindrical, Leader-Novaxa, Milan, Italy; 3. 3 mm × 10 mm, internal hex) and the other eight were sandblasted, large-grit and acid-etched (SLA) implants (IMPLUS (R) Cylindrical,Leader-Novaxa,Milan, Italy; 3. 3 mm x 10 mm, internal hex). All of the dental implants were inserted into the healed extraction sockets of the mandible of two adult male Beagle dogs. Half of the dental implants were designed to be healed beneath the mucosa and the other half were intended to be healed transgingivally and were immediately loaded by acrylic resin bridge restoration. Three types of tetracycline fluorescent labels, namely calcein blue, alizarin complexone and calcein, were administered into the veins of the Beagle dogs 2,4, and 8 weeks after implant placement respectively for fluorescent evaluation of newly formed bone peri-implant. Both Beagle dogs were euthanized 12 weeks after implant insertion and the mandible block specimens containing the titanium implants and surrounding bone and soft tissue of each dog were carefully sectioned and dissected. A total of 16 hard tissue slices were obtained and stained with toluidine blue for microscopic examination and histomorphometric measurements. Histological observation was made for each slice under light microscope and laser scanning confocal microscope (LSCM). Comparison on new bone formation around titanium implants of each group was made and mineral apposition rate (MAR) was calculated for each group. Results: Dental implants prepared by selective laser melting had achieved satisfying osseointegration to surrounding bone tissue after the healing period of 12 weeks. Newly formed bone tissue was observed creeping on the highly porous surface of the SLM implant and growing into the pores of surface structure. Higher MAR values were shown for SLM implants compared with SLA implants (P <0. 01 ). Conclusion: Dental implants prepared by selective laser melting could promote early bone healing and improve mineral apposition rate.
