Janus kinase 2,myeloproliferative leukemia virus and tet encogene family member2 mutations affect a variety of cytokines signal transduction pathway in BCR/ABL-negative myeloproliferative neoplasms (MPN). In the influence of mutation load,co-mutation and genetic susceptibility,these mutations can induce different MPN phenotypes,and affect the characteristics of patients,the distribution of peripheral blood cells and prognosis. But how these mutations contribute to disease initiation,development,and transformation needs further reseach.

OBJECTIVETo evaluate the effect of Qufeng Zhidong Recipe (QZR) on the head tic behavior, and the mRNA expressions of Notch1 and dopamine D2 receptor (D2R) in tic disordered mice.
METHODSMouse model like wet-dog shake head tic disorder was established by peritoneal injection of 5-HT2A/C agonist DOI for 14 successive days. The model mice were divided into three groups, the model group, the Chinese medicine (CM) treated group and the Western medicine (WM) treated group, they were intervened respectively with distilled water, QZR (10 g/kg) and haloperidol (1 mg/kg). Besides, a normal control group was set up and gastrogavaged with distilled water. The effect of intervention was evaluated 2 weeks later by estimating the head tic and the creeping distance of animals, and the mRNA expressions of D2R and Notch1 in corpus striatum and prefrontal cortex regions were detected using Real-time PCR.
RESULTSThe wet-dog shake response and the creeping distance of mice were significantly reduced after intervention in both intervened groups, showing insignificant difference between the effects of CM and WM (P > 0.05). The expression of D2R mRNA in corpus striatum was higher than that in the prefrontal cortex (P < 0.01), at the prefrontal cortex, it was 151 +/- 30 in the CM group and 180 +/- 41 in the WM group, and at the corpus striatum, 710 +/- 64 and 850 +/- 80 respectively, all higher than those in the model group (P < 0.05). While the Notch1 mRNA expression in model mice were lower at the prefrontal cortex than at the corpus striatum (P < 0.05). After intervention it was 55 +/- 20 in the CM group and 48 +/- 23 in the WM group at the prefrontal cortex, all significantly lower than that in the model group (P < 0.05).
CONCLUSIONDOI-induced wet-dog shake response could well simulate the clinical characteristics of tic disorder; QZR could improve the tic behavior and creeping distance in the model mice. The up-regulation of D2R mRNA expression after QZR intervention may be related with the down-regulation of Notch1 expression, this findings is worthy of further studies.

Purpose::The reconstruction of Allen's type IV fingertip amputation is a clinical challenge. Our team designed bilateral unequal-sized hallux osteo-onychocutaneous free flaps for the long-term reconstruction of Allen's type IV fingertip amputation and conducted a retrospective study with a 5-year follow-up aims to evaluate the effects of this technique.Methods::A retrospective analysis with a 5-year follow-up including 13 patients with Allen's type IV fingertip amputation who were admitted to our hospital from January 2010 to January 2017 was conducted. The patients were treated with bilateral unequal-sized hallux osteo-onychocutaneous free flaps. The operation time, intraoperative blood loss, and complications were recorded, and the survival rate of the transplanted flaps was calculated. During the 5-year follow-up after operation, the nail growth time was recorded and the finger appearance was observed. At the last follow-up appointment, the length, width, and girth of the reconstructed fingertip and contralateral normal fingertip, range of motion of the reconstructed fingertip and contralateral normal fingertip, Semmes-Weinstein test (for the evaluation of tactile sensation), and two-point discrimination testing results were recorded. SPSS 22.0 software was used for the statistical analysis and the data are presented as mean ± SD.Results::The mean operation time was (5.62 ± 0.51) h, the mean intraoperative blood loss was (34.15 ± 3.13) mL, and the survival rate of the transplanted flaps was 100%. During the 5-year follow-up, the average nail growth time was (10.14 ± 1.98) months and the average bone union time was (3.78 ± 0.91) months. The length, width, and girth of the reconstructed fingertip were (31.52 ± 3.73) mm, (17.82 ± 1.74) mm, and (59.75 ± 3.04) mm, respectively, which did not differ from those of the contralateral normal fingertip. The range of motion of the reconstructed fingertip was (12.15 ± 2.79) degrees which is different from that of the contralateral normal fingertip. The average tactile sensation evaluated via the Semmes-Weinstein test and the average two-point discrimination test of the reconstructed fingertip were (0.39 ± 0.17) g and (7.46 ± 1.14) mm, respectively, which were not different from those of the contralateral normal fingertip. The average Maryland score of feet in the donor area was 87.66 ± 7.39, which was satisfactory.Conclusion::Bilateral unequal-sized hallux osteo-onychocutaneous free flaps are an effective method to reconstruct Allen's type IV fingertip amputations with a satisfactory appearance and good sensory function.

OBJECTIVETo identify the fibrinogen (Fg) gene mutations in a Chinese pedigree of congenital afibrinogenemia.
METHODSThe plasma Fg activity and protein of the proband and his family members were detected. Genomic DNA was isolated from the peripheral blood mononuclear cells. All the exons and exon-intron boundaries of fibrinogen gene were amplified by PCR and sequenced thereafter.
RESULTSTwo mutations, 7972 del G in FGB and T2543A in FGG, were found in the proband.
CONCLUSIONSFGG2543 is a polymorphism site, which lead to the polymorphism of gamma144 I/K. The G deletion at base 7972 of FGB contributes to the frameshift mutation after amino acid 419, resulting in the truncated beta chain without the terminal 27 amino acids. The latter may contributes to the pathogenetic mechanisms in Chinese congenital afibrinogenemia patients. The G deletion at base 7972 of FGB is identified for the first time.
