1.The clinical management and prevention of tracheo- innominate artery fistula after ;tracheostomy
Chinese Journal of Postgraduates of Medicine 2016;39(9):799-801
Objective To explore the cause, clinical feature, rescue measures and prognosis of tracheo-innominate artery fistula (TIF). Methods From January1995 to January 2015, there were 621 patients who were performed tubotomy, and 8 patients had TIF. The diagnosis of TIF were established by surgery exploration or autopsy. Results The interval between tracheostomy and TIF was 8- 78 d. Before TIF, hemoptysis occurred in 4 patients. When TIF occurred, bedside aid was performed and 4 patients quickly died of asphyxia because of massive blood in the trachea. The others lived long enough to reach the operating room. The family of 1 patient refused surgical therapy and he eventually died. Three patients accepted median sternotomy. One patient underwent vascular repair and died after surgery because of infection in repaired area. The other patients accepted ligation of the innominate artery without suction drains in the mediastinum and died after surgery because of re-bleeding due to mediastinal infection. The last one patient underwent ligation of the innominate artery with suction drains in the mediastinum, and was still alive without long-time neurological complications and re-bleeding after a follow-up of 14 months. Conclusion A prompt diagnosis and surgical intervention can save the life of TIF patient. Prevention is very vital because of the high mortality of this disease.
3.Analysis of the relevant factors for ischemic necrosis of the talus fracture.
China Journal of Orthopaedics and Traumatology 2015;28(4):368-370
OBJECTIVETo explore the relationship of the classification of talus fracture and surgery methods with avascular necrosis.
METHODSFrom March 2009 to November 2013, 78 patients with talus fracture were treated, of them, 43 cases were followed up from 2 to 5 years. There were 27 males and 16 females, aged from 17 to 65 years old with the mean of 38.6 years. Thirty-nine cases had talar neck injury and 4 cases had talar body injury. Different treatments were performed according to different injury conditions. The time from injury to treatment was from 6 to 48 hours. The effect of classification of talus fracture and surgery methods on avascular necrosis was analyzed.
RESULTSIn 43 cases,19 cases occurred avascular necrosis, including talar neck fracture of type I in 2 cases, type II in 5 cases, type III in 5 cases, type IV in 5 cases and talar body fracture in 2 cases (combined with talar neck fracture). And 29 patients were treated with operation, there was no statistically significant differences in avascular necrosis with different operations.
CONCLUSIONCompared with talar body fracture, talar neck fracture is more easily to develop into avascular necrosis. In the 4 types of talar neck fracture, the possibilities of type III and IV were the most ones.

Chinese Journal of Primary Medicine and Pharmacy 2016;23(21):3291-3293
Objective To investigate the clinical values of extracapsular invasion at sentinel lymph nodes in patients with breast cancer.Methods From Jan,2010 to Jan,2013,80 patients underwent axillary lymph node dissection due to sentinel lymph nodes invasion were enrolled in this prospective study.Patients were signed to extracapsular at sentinel lymph nodes positive group (n =45)and control group (n =35)according to the intra -operative pathology.The primary outcome was rate of positive non -sentinel lymph nodes and the second outcomes were 3 -year recurrence -free survival,mortality and health -related quality of life.Results Compared with the control group,the patients in extracapsular at sentinel lymph nodes positive group got a significantly higher rate of positive non -sentinel lymph nodes (91.11% vs.28.57%,χ2 =33.321,P <0.001 );a significantly lower rate of 3 -year recurrence -free survival(57.78% vs.88.57%,χ2 =9.114,P =0.003);a significantly higher rate of mortality (17.78% vs.2.86%,χ2 =4.390,P =0.036);and a significantly lower level of health -related quality of life[(78.43 ±12.43)vs.(87.54 ±11.89),t =11.324,P =0.000].Conclusion Extracapsular invasion at sentinel lymph nodes was a reliable predictor for non -sentinel lymph nodes invasion and long -term clinical outcomes.
6.Pathogeneses of erectile dysfunction after rectal cancer treatment.
National Journal of Andrology 2014;20(6):558-561
Rectal cancer is a common malignancy in the alimentary tract with an increasing incidence, the current treatments of which include surgery, radiotherapy, chemotherapy, and integrated comprehensive options. Sexual dysfunction, especially erectile dysfunction (ED), is one of the commonest complications in men after rectal cancer treatment and is generally attributed to the damage to the pelvic autonomic nerves. However, recent studies show that ED after rectal cancer treatment is a complex pathophysiological process associated with neurogenic, vasculogenic, and psychological factors. This article reviews the pathogeneses of ED after rectal cancer treatment in order to provide some theoretical evidence for its prevention and treatment.

Health Laboratory 2016;5(1):5-11
Background:Chronic neutrophilic leukemia (CNL) is a rare myeloproliferative neoplasm (MPN), since the first description of CNL in 1920, more than 150 cases have reported in the literature. The World Health Organization (WHO) recognizes CNL, as a MPN and, for the frst time, provides recognized criteria to permit the operational classifcation of this poorly defned disease. Until recently, the molecular pathogenesis of CNL was unknown and the diagnosis was based on morphological aspects, clinical criteria and exclusion of known genetic entities like the Philadelphia translocation indicative of CML, or JAK2 mutations indicative of MPNs. Recent discovery of highfrequency granulocyte-colony stimulating factor receptor (CSF3R) mutations in CNL identifes a new major diagnostic criterion, and lend more specificity to the WHO diagnostic criteria for CNL, which are variably applied in routine clinical practice. In 2013 Maxson et al., and Pardanani and colleagues identified granulocyte-colony stimulating factor 3 receptor (CSF3R) mutations in 8 of 9 (89%), and in 13 of 13 (100%) patients with CNL, respectively. CSF3R mutations fall into 2 classes: nonsense or frameshift mutations that lead to premature truncation of the cytoplasmic tail of the receptor (truncation mutations) and point mutations in the extracellular domain of CSF3R (membrane proximal mutations). These nonsense or frameshift mutations truncate the cytoplasmic tail of CSF3R, impair its internalization,and alter its interactions with proteins such as SHP-1/2 and SOCS family members. These structural and functional alterations are thought to perturb the capacity of CSF3R to regulate granulocyte differentiation and to increase granulocytic proliferative capacity. Thetwo types of CSF3R mutations may have differential susceptibility to classes of tyrosine kinase inhibitors,with CSF3R truncation mutations showing activation of SRC family–TNK2 kinase signaling and sensitivity to dasatinib, and CSF3Rmembrane proximal mutations strongly activate the JAK/signal transducer and activator of transcription pathway and are sensitive to JAK kinase inhibitors such as ruxolitinib.The most common CSF3R mutation in CNL is themembrane proximal mutation: T618I. On September 2012 we got a case (a 67-years-old Chinese man), which had fulflled the WHO diagnostic criteria for CNL with a novel mutation site of colony stimulation factor 3 receptor (CSF3R). In our case was identifed a membrane proximal mutations CSF3RT618I and also a unreported novel mutation site of CSF3R-H54A in the CD34+ and CD15+ cell fractionsby sorting bone marrow samples (BD FACSAria™ III; BD Biosciences) using a PCR-based DNA pyrosequencing method. Thus, we sought to determine CSF3R-FL, CSF3R-T618I, CSF3R-H54A mutations have some correlation with molecular pathogenesis of CNL.Objective:To determine CSF3R-FL, CSF3R-T618I, CSF3RH54A mutations that have some signifcance on the molecular pathogenesis of CNL.Materials/Methods:1. Plasmid construction. Plasmids were constructed by PCR amplifcation of the insert, restriction digestion and ligation using standard molecular biology methods, briefly: the host vectors pLV-EF1α-EYFP-N, pLP-2, pVSV-G, pLP-1 gag pol were purifed with Omegabiotek maxi prep kit and digested by restriction enzymes (ECO RI, NOTI). The linearized vectors were purified from agarose gel using a AxyPrep TM DNA Gel Extraction Kit and the concentration of the samples was estimated on an agarose gel stained with ethidium bromide.The inserts (CSF3R-FL, CSF3R-T618I, CSF3R- H54A) were generated by PCR, the sequences of the primer-pairs used and the conditions of the PCR reactions. The amplifed DNA fragments were purifed from agarose gels using AxyPrep TM DNA Gel Extraction kits and digested by ECO RI, NOTI was used to linearize the acceptor vector. Enzymatic reactions in the case of the i) insert: 100–3000 ng purifed PCR product was digested by appropriate amount of enzyme and 4 µl of 10x reaction buffer in 40 µl of fnal volume for overnight at the appropriate temperature; ii) vector: 2000–4000 ng plasmid DNA was digested by appropriate amount of enzyme and 2 µl of 10x reaction buffer in 20 µl of fnal volume for 4 hours at the appropriate temperature. When necessary Research on the Influence of new oncogenic CSF3R mutations in Chronic Neutrophilic Leukemia Otgonbat Altangerel1, Ming Feng Zhao2, Wu Ri Mao21Department of Internal Medicine, Division of Hematology, Mongolian National University of Medical Sciences, Mongolia 2Department of Hematology, Tianjin First Central Hospital, First Central Clinical College of Tianjin Medical University,P.R. China11 the digested fragments were purifed again and the concentrations of the inserts were estimated on agarose gels, as described above. A 1:3 vector: insert molar ratio was used for the ligation reactions. Chemically competent DH5α Escherichia coli bacteria were transformed with the products of the ligation reactions and were grown on Luria Bertrani (LB) agar plates containing the required antibiotic, such as ampicillin (Sigma). A day later single colonies were picked from the plate, inoculated into and grown overnight in LB medium containing with ampicillin. Plasmids were purifed from the overnight cultures as above and tested by restriction mapping for the presence of the insert. Selected clones were sequenced by Sanger sequencing.2. Lentiviral packaging system we used 3 main components, such as the lentiviral expression vector(Plasmid DNA of CSF3R-FL, CSF3R-T618I), the lentiviral packaging plasmids (pLP-1, pLP-2 plasmids that encode for gag, pol, and rev from the HIV or FIV genome and pVSV-G), 293TNN producer cells. We seed 1X105 293TNN cells per 10 cm2 culture plate in 2-3 ml of culture medium containing DMEM medium supplemented with 4 mM L-glutamine, 4.5 g/l glucose, and fetal bovine serum (10%) without antibiotics. Grow for 18-24 hours at 37 °C with 5% CO 2 so that the cell density reaches ~60 - 80% confluency at the time of transfection. We used a GFP as a positive control, to confrm transfection experiment was successful. Then we collected the cell culture supernatant, which is containing infectious pseudoviral particles.3. Transduction of Pseudotyped Viral Particles into the primary cell of mouse. In the fnal step we have used the Mouse Colony Forming Unit Assay using MethoCultTM to assess the effects of CNL-associated oncogenes on the morphology and number of primary murine cells derived bone marrow. For this purpose cells are transduced with either control, which is without viral construct or a construct expressing the oncogene of interest (CSF3R-FL, CSF3R-T618I).Results:1. On the Plasmid construction step we successfully extracted and purifcated of recombinant plasmids ofCSF3R-FL and CSF3R-T618I cloning, but we still didexperiment to obtain the recombinant plasmid CSF3R- H54A cloning.2. After 24 hours of transfection 293TNN Cells with Packaging Plasmids and the Expression Construct, cells we visualized with green fluorescence protein under the fluorescence microscope.3. The both two of CSF3Rcloning were capable of transforming murine colony forming cells. After transforming, CFU-GM colonies were counted manually by light microscopy seven days after plating. We found that the membrane proximal mutation (T618I) transformed CFU-GM colonies number was more than the full length non-mutants (CSF3RFL), which indicates that T618 mutation of CSF3R conferred the clonal advantage of CNL leukemia cells.Conclusions:1. The establishment of the plasmid reconstruction, lentiviral packaging system and Mouse Colony Forming Unit Assay were done successfully.2. We confrmed the transformation capacity of the CSF3R mutations, especially CSF3R-T618I was higher than CSF3R-FL. This result demonstrates that T618 mutation of CSF3R conferred the clonal advantage of CNL leukemia cells.3. Further studies will be continued and are needed to prove the effects of the novel mutation site CSF3RH54A on the transduced murine bone marrow progenitor cells by using CFC assay

Objective To explore the diagnostic value of MRI on fetal congenital limb deformities.Methods Sixteen pregnant women,aged from 22 to 40 years (average 29 years) and with gestation from 22 to 39 weeks (average 29 weeks) were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound studies. Acquisitions consisted of coronal, sagittal, and axial slices relative to the fetal brain, spine, thorax, abdomen, especially limbs using 2D FIESTA sequences. Prenatal US and MR imaging findings were compared with postnatal diagnoses (4 fetuses) or autopsy (12 pregnant women,13 fetuses). Postnatal evaluation included US, MR imaging, computed tomography, and physical examination. Results Of the sixteen pregnant women (15 with a single fetus and 1 with twin fetuses) ,17 fetuses were found. Those limb deformities of sixteen pregnant women included congenital both upper extremities amelia (1 case), sirenomelia sequence (1 case), micmmelia (5 cases, 1 of which were twins),bilateral clenched hands (2 cases), right pelydactyly (1 case), simple right ectrodactyly (1 case), right dactylolysis(1 case), simple club foot (2 cases), hydrocele spinalis with club foot (2 cases), 1 of the 2 cases with bilateral clinodactyly. In 14 of 16 cases, the diagnoses established by MR imaging were correct when compared with postnatal diagnosis, and prenatal MR diagnosis was inaccurate in 2 cases. Conclusion Prenatal MRI is effective in the assessment of congenital limb deformities of fetuses, it can yield information additional to that obtained with US, and further correct US diagnosis.
