Objective to explore the correlation between interferon-γ receptor(IFNGR)2 amino acid sites Val14Met and GIn64Arg polymorphism and atherosclerosis plaque stability in Yunnan Han nationality.Methods The patients with unstable atherosclerotic plaque in our hospital from March 2014 to March 2015 were collected as the observation group and contemporaneous patients with stable atherosclerotic plaque/non-plaque as the control group.The peripheral venous blood was collected for extracting genomic DNA.IFNGR Va114Met and GIn64Arg loci genotype was detected by the PCR product direct sequencing method.The sequencing results were analyzed by adopting the DNAStar and GeneTool software.The levels of plasma cytokines(IFN-γ)was detected by the flow cytometry.Results Two hundreds and four native Han patients were included in this study,including the observation group,109 cases,age(76.89±12.08)years old;the control group,95 cases,age(65.99±16.32)years old.The polymorphism change of IFNGR1 Vall4Met loci was not found irn the two groups.In the observation group,the frequency of IFNGR2 Gln64Arg genotype AA was 51.95％(40/77),which of AGwas 53.06 ％(52/98)and which of GG was 58.62％(17/29);in the control group,the frequencies were 48.05 ％ (37/77),46.94 ％ (46/98) and 41.38 ％ (12/29),chi-square test,P =0.824.The IFNGR2 Gln64Arg genotypes AA,AG and GG had no relation with atherosclerotic plaque stability.The A and G allele frequencies in the observation group were 52.38％ (132/252)and 55.13 ％ (86/156)respectively,which of the control group were 47.62 ％ (120/252)and 44.87％ (70/156),chi-square test's P=0.661.The IFNGR2 Gln64Arg A/G allele had no relation with atherosclerotic plaque stability.By Hardy-Weinberg genetic balance test,the gene frequency in this sample population was in accordance with the genetic equilibrium law.The plasma IFN-γ level in the observation group was(4.60 ± 1.91)ng/mL,which in the control group was (4.88 ± 2.10)ng/ mL,the difference was not statistically significant(P=0.318);the plasma IFN-γ content had no relation with atherosclerotic plaque stability(P=0.308).Conclusion The genetic polymorphisms of IFNGR can not serve as a warning indicator of atherosclerotic plaque stability.

Schwannomas are benign, slow-growing peripheral nerve sheath tumors commonly occurring in the head, neck, and flexor regions of the extremities. Although most schwannomas are easily diagnosable, their variable morphology can occasionally create difficulty in diagnosis. Reporting pathologists should be aware that schwannomas can exhibit a broad spectrum of morphological patterns. Clinical and radiological examinations can show correlation and should be performed, in conjunction with ancillary tests, when appropriate. Furthermore, deferring a definitive diagnosis until excision may be necessary for small biopsy specimens and frozen sections. This report underscores these challenges through examination of two unique schwannoma cases, one predominantly cellular and the other myxoid, both of which posed significant challenges in histological interpretation.

Objective To investigate the safety and feasibility of laparoscopic removal of exogenous caesarean scar pregnancy (CSP).Methods From January 2009 to May 2011,71 patients with CSP treated in Shengjing Hospital of China Medical University were studied retrospectively.Thirty-nine patients were treated with hysteroscopic excision of CSP,while 32 patients were treated with laparoscopic surgery.The following clinical parameters were compared,including intraoperative blood loss,quantity of postoperative uterine drainage,postoperative hospital days,the time for the mass absorption and the return of β-hCG to normal were studied.Results Two cases in the hysteroscopic group were transformed to abdominal surgery because of introperative bloody loss,the 37 cases underwent hysteroscopic surgery successfully with the ultrasound supervision and guidance.Laparoscopic surgery were successfully completed in all 32 cases.In hysteroscopic group,the operation time,the time for the return of serum β-hCG to normal,postoperative uterine drainage volume and the postoperative hospital stay were (44 ± 18) minutes,(27 ±5) days,(38 ± 12) ml,(3.8 ±0.7) days.While,in laparoscopic group,they were (100 ±21) minutes,(17 ±4) days,(19 ± 6) ml,(3.5 ± 0.6) days,respectively,the differences reached statistically significant (all P ＜ 0.05).But the amount of intraoperative bleeding were was (113 ± 63) ml in hysteroscopic group and (109 ±59) ml in laparoscopic group,the difference was not statistically significant (P ＞0.05).The duration of absorption of mass were (88 ± 17) days in hysteroscopic group.In laparoscopic group,the mass were completely removed.Conclusions Laparoscopic exicion of CSP could be suitable in treatment of exogenous CSP which offers advantages including prompt recovery,blood loss and hospital stays.This management could repair the uterine scars,reduce the reoccurring risk and conservate the fertility potential.

[ ABSTRACT] Tyrosine kinase inhibitors ( TKIs) are now advocated as the first-line treatment for chronic myeloid leukemia ( CML) , but facing resistance and relapse .Leukemia stem cells ( LSCs ) are leukemia-initiating cells as the source of resistance and relapse .It is therefore important to discover the molecular biomarker of LSCs for developing anti -LSC strategies in leukemic therapy .15-Lipoxygenase (15-LO) is a key enzyme in the pathway of arachidonic acid and plays an important role in the occurrence and development of CML , which is specifically required for chronic myeloid LSCs . This review summarizes the influence of 15-LO on the chronic myeloid LSC characteristics of marked survival , self-renewal, proliferation , differentiation and apoptosis .

Objective To evaluate the application value of combination of low kV,low mAs,and iterative model reconstruction (IMR) in carotid CT angiography.Methods Forty patients (BMI 20-25 kg/m2) were enrolled and randomly divided into routine dose group(20) and low dose group(20),The parameters in routine dose group were 120 kV,automatic mAs,and filter back projection(FBP);and that in low dose group were 80 kV,automatic mAs but upper limit 150 mAs,and FBP or IMR.All patients received the injection of 32 ml of iopamidol(370 mg I/100 ml) at a flow rate of 4 ml/s,followed by 50 ml normal saline at the same rate.The CT value and image noise(SD)of the aortic arch,left carotid artery bifurcation,and right carotid artery of rock bone were measured with region of interest(ROI) method,and then signal to noise ratios (SNR) and contrast to noise ratio (CNR)of image were calculated.The image quality was evaluated by two radiologists using a subjective four points scale on multiplanar reformated (MPR),maximum density projected (MIP) and volume rendered (VR) images.Volume CT dose index (CTDIvol),dose length product (DLP),and the effective dose (E) of each patient were recorded.Results CT values of carotid artery[(479.87 ± 70.28),(514.78 ± 82.69),(436.50 ± 89.87) HU] in low dose group were significantly higher than those in routine dose group [(295.63 ± 34.75),(325.09 ± 37.81),(286.93±36.46)HU](t =-6.47,-5.76,-3.66,P＜0.05).The SNR and CNR of IMR reconstructed image in low dose group were significantly higher than those of FBP reconstructed image in routine dose group (t =-7.54,-3.55,-5.31,-7.13,-5.28,-8.35,P＜0.05).The image quality of FBP reconstructed images in routine dose group and IMR reconstructed images in low dose group were all enough for diagnosis.The image quality of FBP reconstructed images in low dose group was significantly poorer than that in routine dose group and IMR reconstructed images in low dose group (Z =-2.87,-3.69,P ＜0.05).The effective dose in low dose group (0.57 ±0.13) mSv was 73％ less than that in routine dose group (2.22 ± 0.36) mSv.Conclusions Using low kV,low mAs,and IMR would help to obtain good carotid CT angiographic images and low radiation dose.

This study was aimed to compare the relative cytotoxicity of the five common orthodontic bonding materials (Concise. Mon-lok , Ortho-One, Super C, Transbond) using cell culture technique. DNA synthesis of the fibroblasts was assessed by 3H-thymidine uptake to evaluate the effect of the bonding materials on the growth of the cells. The human gingival fibroblasts were explanted from the buccal gingiva of 10 year-old girl and cultured in a-MEM/10% FBS/1% antibiotics medium, 37degreesC, 5% CO2 incuvator. The gingival fibroblasts were tested with the medium into which the bonding materials had been soaked for 1 week. Or the bonding materials were placed on the cells immediately or 2 weeks after polymerization. After 22 hours, 3H-thymidine was added into the microtest wells and after 24 hours, the uptake of 3H-thymidine was determined by liquid scintilation counter. The results of this study were as follows. 1. DNA synthesis was significantly decreased with Super C and Transbond than Ortho-One, when treated with medium into which the bonding materials had been soaked for 1 week. 2. DNA synthesis was significantly decreased with Concise, Super C and Transbond than control, when treated immediately after polymerization. 3. DNA syntehsis was significantly decreased with Concise, Super C and Transbond than Ortho-One, when immediately after polymerization. 4. There was no significant difference in DNA synthesis between the bonding materials, when treated 2 weeks after polymerization.

This study was aimed to establish an HPLC method to simultaneous determine 6 kinds of monoester and diester aconitum alkaloids. The content of alkaloids in aconite roots, black and white prepared lateral root of aconite and the compatibility of aconite roots with rhubarb were determined. This study provided reference for the interpreta-tion of the attenuation of processing and compatibility of medicines from chemical component aspect. The HPLC analysis was performed on a Phenomenex Gemini C18 (4.6 mm í 250 mm, 5 μm) with 40 mmol·L-1 ammonium ac-etate (adjusted to pH 9.8 with ammonia water) and acetonitrile as mobile phase, with a gradient elution at the flow rate of 1.0 mL·min-1 and a detection wavelength of 235 nm. The results showed that 6 alkaloids in aconite roots achieved favorable separation and a good linearity relationship (r > 0.999) over the studied concentration range. The extraction recoveries were ranged from 96.9% to 102.4% for the 6 alkaloids. The content of diester alkaloids de-creased markedly in processed products and the compatibility of aconite roots with rhubarb compared with the raw a-conite roots. It was concluded that this method was stable, reliable, simple and practical. It can be used for the si-multaneous determination of 6 kinds of monoester and diester aconitum alkaloids in aconite roots. This processing and compatibility can significantly reduce the content of alkaloids in aconite roots in order to reduce its toxicity.
