The patient was treated as pharyngeal foreign body sensation for six months. Laryngeal endoscopy: one about 1 cm x 2 cm x 2 cm, hard, smooth bulge in hypopharyngeal wall at the plane of epiglottis valley. The cervical MRI showed that the C3-C4 disc herniation and degeneration of the C3-C4 vertebrae. Cervical CT showed the C3-C4 disc osteophyte formation and forward bulge. After orthopedic consultation, the patient was diagnosed as esophageal cervical spondylosis. C3-C4 diskectomy and vertebral interbody bone grafted with plate fixation were undertaken. At postoperational day 2, the pharyngeal foreign body sensation disappeared.

Objective 22q11 microdeletion is featured with hemotological dysfunction,among others:hypocalcemia,thrombocytopenia and megathrombocyte.This study was trying to work out the platelet characteristics of 22q1 1 microdeletion patients and its potential clinical application.Methods A total of 80 cases who had undergone open-heart surgery were selected and confirmed with fluorescence in situ hybridization (FISH) to have 22q1 1 microdeletion among 40 cases while the others were negative.The relevant data in full blood routine of all the 80 cases in hospital information system (HIS) then were collected and analyzed with suitable statistical methods.Results The mean platelet volume in microdeletion group was statistically higher than that in the control group [(11.20 ± 1.94)fL vs (8.95 ± 1.58) fL,P ＜0.01].The area under the receiver operating characteristic (ROC) curve was 0.82,meaning significant predictive values.The corresponding sensitivity and specificity for mean platelet volume (MPV) =10 fL were 70.0 ％ and 80.0 ％,respectively.Conclusions MPV in congenital heart defect patients with 22q11 is significantly higher than those without 22q11.It is an effective method for preliminary screening 22q11.Being obtained from full blood routine data,it is economic and quick.MPV =10 fL can be used as a cutoff for guidance for irradiated blood transfusion postoperatively.

The forkhead box O (FoxO) transcription factor family plays an important role in cell functions, including metabo-lism, apoptosis, cellular proliferation, stress reactions, DNA repair, and immune response. As a member of this family, forkhead box O3a (FoxO3a) regulates its target genes by modulating histone modifications, including phosphorylation, acetylation, and methylation. FoxO3a expression is abnormally downregulated in urologic neoplasm. Protein modifications and FoxO3a activity are mainly con-trolled by PI3K/Akt signal pathway and other signaling pathways. FoxO3a is also involved in the initiation, progression, and prognosis of urologic neoplasm. This review focuses on the function of FoxO3a in urologic neoplasm and elucidates the regulatory mechanisms involved. This article will provide novel strategies to clinical diagnosis and drug therapy of urologic neoplasms.

Objective:To establish and validate the rat model of syndrome of stagnation of liver qi,followed by a primary study on this model with 1H NMR based on metabonomics to explore the essence of syndrome of stagnation of liver qi. Methods:Twelve Wistar male rats were randomly divided into two groups(model group and control group).The rats of model group were restrained by special equipment for 21 days to get into stagnation of liver qi.The behavior,fluid consumption test and plasma CORT of rats were recorded.At 22th day,animals were sacrificed and biopsies of gastric mucosa and adrenal gland were collected for pathological check,and serum samples for 1H NMR spectroscopy.The NMR data were analyzed using principal component analysis.Results:There were abnormal behaviors,such as decrease of elusion,slackness,looser stools,and matte fur were observed among model group rats.After one week the body weight of model group was significantly lower than that of control group(P

Aim To investigate the direct effects and mechanism of carvedilol on HERG channel stably expressing in human embryonic kidney-293(HEK293) cells.Methods Whole-cell patch-clamp technique was used to record HERG current and kinetic curves in single cells.Western blot methods were used to investigate the expression of HERG channel in different concentration of carvedilol.Result Carvedilol decreased HERG current in a concentration-dependent manner with an IC50 539.6 nmol?L-1,Hillslope-0.64.The time constants of onset of inactivation and deactivation were accelerated.Other kinetcs(activation,inactivation,recovery from inactivation)had no significant changes.Based on western result,carvedilol had no effect on the generation and trafficking of HERG protein.Conclusion Carvedilol inhibits the transfected HERG channels by influencing the open state which is the probable anti-arrhythmic mechanism.There is no relationship between carvedilol and HERG channel expression.

Objective To explore the application of the evidence-based case report method in the standardization training of resident physicians in the department of endocrinology. Methods Fifty-one resi-dents recruited from the endocrinology department were randomly divided into the experiment group (26 cases) and control group (25 cases). The evidence-based case report method was conducted in the ex-peri-mental group, while the traditional clinical teaching mode was applied in the control group. The re-sults of the examination of two groups including the theoretical test and skill test were compared and the question-naire survey was conducted to find out the differences of students' interest in learning, clinical skills and satisfaction. All data were compared using t test. Results There was no significant difference in theoretical test between the two groups (P>0.05). The total score of the skill test in the experimental group was (85.13 ±4.63) and the control group was (76.79 ±3.11) (P=0.000). The students in the experimental group showed that the teaching method had more significant effects on improving their learning interest and initiative, clinical thinking ability, clinical work ability, literature review ability and medical article writing ability. Scores of satisfaction with teaching methods (total score was 10) for experimental group were (9.69 ±0.34), which was also significantly higher than those in the control group (8.01 ±0.39) (P=0.000). Conclusion The application of evidence-based case report teaching method in the standardized training of resident physicians in department of endocrinology is worthy of being perfected and further popularized in clinical teaching work.

Objective To construct an eukaryotic expression vector of human B-cell translocation gene 2 (BTG2), to express the FLAG-tagged BTG2 protein in HeLa cells,and to supply an experimental tool for investigating the function of BTG2 gene.Methods The full-length BTG2 fragment was obtained by PCR and inserted into the multiple cloning site of pcDNA3.1 (+)vector. Oligo DNA encoding FLAG tag was designed and inserted into pcDNA3.1(+)-BTG2 to construct another vector pcDNA3.1(+)-FLAG-BTG2.The HeLa cells were divided into pcDNA3.1(+)empty vector group,pcDNA3.1(+)-BTG2 group and pcDNA3.1(+)-FLAG-BTG2 group.The HeLa cells were transfected with recombinant plasmids.Western blotting using anti-FLAG antibody was performed to detect the expression of FLAG-BTG2 protein in HeLa cells.Results The sequence of the vector was verified by both BamH Ⅰ endonuclese digestion and DNA sequencing. The Western blotting analysis confirmed that FLAG-fused BTG2 was detected in pcDNA3.1(+)-FLAG-BTG2 group but not in empty vector or pcDNA3.1(+)-BTG2 groups. Conclusion The eukaryotic expression vector pcDNA3.1(+)-FLAG-BTG2 is successfully constructed and FLAG-tagged BTG2 protein is expressed in HeLa cells.

Auto liver transplantation (ALT) is a treatment option for patients with liver space-occupying lesion that could not be removed by conventional surgery and severe liver trauma,which also helps alleviate the shortage of donor liver.But many problems like the preoperative assessment,the tolerance of patients to surgery and anesthesia,delayed postoperative recovery of the liver function,primary non-function,liver failure and hepatic encephalopathy and even death still need to be addressed.Thus,it is particularly important to evaluate the operative indication,completely and accurately assess the preoperative liver function and liver function reserve,and reduce the perioperative mortality and complication in order to improve the prognosis of ALT.Combined with literalure and the experience in our center,this paper summarized the research advance of preoperative assessment in patients with ALT.
