Objective To analyse the clinical efficacy of methotrexate (MTX) combined with intrauterine embryo sac garrotte injection in the treatment of cesarean scar pregnancy (CSP), and discuss its clinical significance. Methods A total of 77 patients with CSP treated in our hospital during June 2013 to December 2016 were selected in this study. Forty patients treated with embryo sac destruction and methotrexate injection were included in the observation group, while 37 cases treated by uterine artery embolization combined with curettage were used as the control group. The time of vaginal bleeding, the time of postoperative blood level of human chorionic gonadotropin (HCG) returned to the normal level, average hospitalization cost and the curative rate were recorded in two groups. All patients were followed up by the outpatient visit. Results In the observation group, the vaginal bleeding time [(22.1±6.7) days vs. (29.5±10.8) days] and treatment cost [(8774.2 ± 714.5) yuan vs. (15258.3 ± 1084.2) yuan] were less than those of the control group (P<0.001). There were no significant differences in the recovery time of HCG [(26.4±9.0) days vs. (25.1±10.4) days] and treatment success rate (87.5%vs. 91.9%) between the two groups (P>0.05). No bleeding or threatened rupture of scar were found in two groups of patients. Conclusion In this study, we take the embryo sac puncture combined with methotrexate injection in the treatment of scar pregnancy. This method has the advantages of low operative difficulty, definite clinical curative effect and low cost

Objective To investigate the effect of intraperitoneal injection of thalidomide on pain behaviors in a mouse model of bone cancer pain. Methods 36 male C3H/HeJ mice were divided randomly into tumor group (n= 18) and sham group (n= 18) ,six mice from each group were chosen to examine the time course of changes in behavior after tumor cells inoculated to the bone. 2 × 105 osteosarcoma NCTC 2472 cells were implanted into the intramedullary space of the right femurs of mice to induce ongoing bone cancer related pain behaviors. The sham group was inoculated by α-MEM without any cells. On the day before inoculation,the tumor mice were divided randomly into tumor + thalidomide group and tumor + vehicle group. The sham group mice were further divided randomly into sham + thalidomide group and sham + vehicle group. Pain ethology indexes such as paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) were observed on 1 d before inoculation and on 3 d ,5 d ,7 d, 10 d, 14 d after inoculation. Results ( 1 ) At day 7 after the operation, compared with sham mice ( 1. 70 ± 0. 33 ) g, PWMT of tumor mice decreased to ( 1.07 ± 0. 30) g (P ＜ 0. 05 ). At day 10, PWTL shortened to ( 12.60 ± 1.69 ) s (P ＜ 0. 05 ) compared with sham mice ( 17.70 ± 1.54 ) s. And the pain behaviors of tumor mice were aggravated along with the development of cancer pain. (2) At day 7 after the operation, compared with tumor + vehicle group ( 1. 07 ± 0.39 ) g, PWMT of tumor + thalidomide group increased to ( 1. 53 ± 0. 39 ) g (P ＜0.05). At day 10, PWTL extended to ( 16.48 ± 1.13 ) s compared with sham mice ( 12.64 ± 1. 56) s (P ＜0. 05 ). Conclusion Intraperitoneal injection of thalidomide can efficiently relieve mechanical hyperalgia and thermal hyperalgia in a mouse model of bone cancer pain.

Objective To investigate the functional changes of brain spontaneous activity in patients with Alzheimer' s disease (AD) and amnestic mild cognitive impairment (aMCI) using resting-state functional magnetic resonance imaging (fMR1), and evaluate the potential value of fMRI marker in clinical diagnosis of AD and aMCI.Methods Twelve AD patients, 12 aMCI patients and 12 normal controls (NC) were assessed by the Minimum Mental State Examination (MMSE) and scanned using the resting-state fMRI.The fractional amplitude of low-frequency fluctuations (fALFF) method was employed to examine the changes of the brain spontaneous activity among the three groups.Results Significant between-group differences were found in the precuneus and the inferior parietal lobe.In the precuneus, the fALFF value in AD patients (mean ± SD : 1.11 ± 0.07) was significantly decreased as compared to NC (1.24 ± 0.11, t =2.89,P =0.012) and aMCI patients (1.34 ±0.17,t =3.49,P =0.004).The aMCI patients demonstrated numerically largest fALFF in the precuneus.In the inferior parietal lobe, the fALFF values in AD patients (0.96 ±0.07) were also significantly decreased as compared to NC (1.11 ±0.07 ,t =4.31 ,P =0.001) and aMCI patients (1.09 ± 0.08, t =3.44, P =0.004).Conclusions AD patients were mostly influenced in the specific regions in terms of brain spontaneous activity, while the aMCI patients showed a compensatory tendency in the precuneus.

OBJECTIVETo observe the influence of H102 on the expression of amyloid protein and amyloid precursor protein in the hippocampus of APP695 transgenic mice.

METHODSThe 9-month-old APP695 transgenic mice were randomly divided into the model group and the H102 group; C57BL/6J mice were adopted as normal control group. The H102 group were injected with H102 in a dose of 3 microl/per mouse in lateral ventricle, once a day, for ten days; while the model group and the control group were injected with saline. The hippocampus and temporal cortex of the brain sections from transgenic mice and wild type female mice were subjected to immunohistochemistry and Congo red histological staining, and observed the difference of the protein expression under microscope. The expression of the APP protein was detected by Western blot.

RESULTSAbeta and APP immunohistochemistry showed density of positive cell in the CA1 region of hippocampus of control group were less than model group. H102 peptide reduced the area, and density of positive cells. Congo red staining showed there were lots of amyloid plagues in the brains of model mice but not in the brains of normal control. And the Western blot showed the content of the APP protein of the model group was much higher than the H102 group. H102 significantly decreased the amyloid plagues.

CONCLUSIONThe expression of APP, Abeta are increased in APP695 transgenic mice, and H102 can decrease the level of APP, Abeta in transgenic mice.

Objective To purify human 14-3-3β (YWHAB) recombinant protein expressed in the E.coli, prepare its antiserum and construct the eukaryotic expression vector for transfecting mammalian cells. Methods The human 14-3-313 recombinant protein expression vector pET30a (+) /YWHAB constructed by the ORF of YWHAB gene and prokaryotic expression vector pET30a (+) was transformed into E.coli BL21 (DE3). The expression of the recombinant protein was induced by IPTG and the protein was purified by affinity chromatography on a Ni-NTA resin. BALB/c mice were immunized by the purified protein, and ELISA and Western blotting were employed to detect the titer and specificity of the antiserum. The open reading flame of YWHAB gene was obtained by PCR, the purified PCR product digested by BamH Ⅰ and EcoR Ⅰ was cloned into the eukaryotic expression vector pEGFP-N1, and the product digested by BamH Ⅰ and Hind Ⅲ was cloned into the eukaryotic expression vector pCDNA3.1 (+). The recombinant vectors were identified by PCR and enzyme digestion. Results The recombinant protein was expressed as a soluble protein with a relative molecular mass of about 32 kD, which was consistent with the expected value. The recombinant protein was purified using affinity chromatography to yield a purity up to 90%. The antiserum had high specificity and titer (1: 50000). The results of PCR and enzyme digestion verified successful construction of the eukaryotic recombinant expression vector pEGFP-N1/YWHAB and pCDNA3.1 (+)/YWHAB. Conclusion The recombinant human 14-3-3β protein, the antiserum and the eukaryotic expression vector obtained may facilitate further functional study in the human 14-3-3β protein.

The effects of intrarenal artery injection of capsaicin on multi- and single-unit spontaneous discharges of renal afferent nerve fibers were investigated in anesthetized rabbits. The results obtained are as follows: (1) intrarenal artery injection of capsaicin (20, 40, and 60 nmol/kg) increased the renal afferent nerve activity (ARNA) in a dose-dependent manner with unchanged arterial pressure; (2) pretreatment with ruthenium red (40 mmol/kg), a capsaicin receptor antagonist, completely abolished the effect of capsaicin; and (3) pretreatment with a nitric oxide synthase inhibitor L-NAME (N(6)-nitro-L-arginine methylester, 0.1 mmol/kg), significantly enhanced the ARNA response to capsaicin. The results suggest that intrarenal artery injection of capsaicin can activate ARNA via capsaicin receptors in anesthetized rabbits and that nitric oxide may be involved in regulating the activity of renal sensory nerve fibers as an inhibitory neurotransmitter.
