Tinnitus is a common disease in otolaryngology. In China, acupuncture has been used as a promising treatment for tinnitus. Yet, the specific effect and safety of acupuncture are still disputable. The ultimate goal of this paper is to formulate a protocol for systematic review and meta-analysis, which can be employed in assessing the benefits and safety of acupuncture on tinnitus. Seven databases should be retrieved from their establishment until June 2020, including PubMed, Cochrane Central Register of Controlled Trials, Excerpt Medical Database, Chinese Biomedical Literature Database, Chinese Science and Technology Periodical Database, China National Knowledge Infrastructure and Wan Fang Database. Randomized controlled trials of acupuncture treatment of tinnitus will be included. The experimental group is acupuncture or combined with additional treatment measures, and the control group is a placebo, sham acupuncture, Cognitive Behavioral Therapy, sound therapy, conventional medication, or same additional treatment. The clinical efficacy rate, Tinnitus Handicap Inventory, Tinnitus Questionnaire, visual analogue scale or other indicators are all concerned in the systematic evaluation of the program. Data collection, selection and extraction should be made separately by different researchers. The quality of the literature will be evaluated by the bias analysis table in the Cochrane Handbook, and Review Manager 5.3 software shall be applied to data analysis. This protocol has made a concrete plan to evaluate whether acupuncture is effective and safe in curing tinnitus. This protocol is suitable for evaluating the effectiveness and safety of acupuncture in curing tinnitus, and is helpful for subsequent evaluation.Open Science Framework Registration DOI 10.17605/OSF.IO/85FCS.

The reports on prenatal ultrasound abnormalities of fetus with 15q11.2 microdeletion are rare. A 30-year-old woman was referred for genetic counseling and prenatal diagnosis at 19 weeks of gestation because of increased nuchal translucency in prenatal ultrasound findings and a history of spontaneous abortion. The cytogenetic analysis showed the karyotype of the fetus was 46,XY, inv(4)(p15q31) and chromosomal microarray analysis detected a 0.512 Mb deletion in 15q11.2 region. We recalled the parents to determine the origination of these chromosomal abnormalities. The pregnant woman chose to continue the pregnancies and finally delivered a healthy male infant at 39 weeks. The fetus inherited the inv(4)(p15q31) from his mother while the deletion in 15q11.2 was identified as de novo. Given the normal phenotype of the mother, it was reasonable to assume that the maternal inherited inv(4) in the fetus would not increase the risk of his abnormal phenotype. However, the pathogenicity of the microdeletion in 15q11.2 for the infant is unknown and long-term follow-up of progeny should be paid more attention. The combined application of traditional banding technique and molecular cytogenetic techniques can not only detect chromosomal structural abnormalities, but also identify the subchromosomal imbalances, which is beneficial to genetic counselling and would offer more guidance to prenatal diagnosis.

Gastrointestinal stromal tumors that present outside the gastrointestinal tract are known for extra-gastrointestinal stromal tumors (EGISTs) and they share the same morphological and immunohistochemical characteristics with gastrointestinal stromal tumors. Here we report a rare case of diffuse primary EGIST arising at peritoneum. A 57-year-old male presented to the hospital with abdominal pain and right lower abdominal tenderness. The core needle puncture biopsy showed epithelial-like cells and the nuclei were ovoid and focally elongated. Immunohistochemical examination was consistent with a primary EGIST of the peritoneum. The patient was treated with Imatinib mesylate. Five months later, there is no complication resulting from treatment. The follow-up abdominal contrast-enhanced CT showed the lesion was significantly decreased in size, and was evaluated as partial response. The patient continued the treatment with Imatinib as prescribed by the oncologist. EGISTs are rare and should be considered in the differential diagnosis of the peritoneal tumors and immunohistochemistry helps to confirm the diagnosis. https://www.selleckchem.com/MEK.html Further study with longer follow-up is desired to characterize these uncommon tumors.

Some acute myeloid leukemia (AML) patients present with features mimicking the classical hypergranular subtype of acute promyelocytic leukemia (APL) but without the typical promyelocytic leukemia/retinoic acid receptor α (PML/RARα) rearrangement. Herein, we report an AML patient resembling APL but with nucleoporin 98/retinoid acid receptor gamma gene (NUP98/RARG) fusion transcript and Runt-related transcription factor 1 (RUNX1) mutation. An 18-year-old male presented at the hospital with a diagnosis of AML. The patient was diagnosed with bone marrow examination. Bone marrow smear displayed 90.5% promyelocytes. Fluorescence in situ hybridization analysis failed to detect the PML/RARα fusion transcript or RARα amplification. While real-time polymerase chain reaction showed positivity for the NUP98/RARG fusion transcript. G-banding karyotype analysis showed a normal karyotype. The patient showed resistance to arsenic trioxide and standard 3 + 7 chemotherapy, but eventually achieved complete remission through the Homoharringtonine, Cytarabine, and Aclarubicin chemotherapy.
