Our purpose is to introduce and analyze the data quality assurance (DQA) protocol of functional magnetic resonance imaging (fMRI). A water phantom was scanned to get DQA indexes. An fMRI sequence was used to get signal noise ratio (SNR) and Drift, which was calculated from maximum difference ratio of the average signal intensity in the region of interest (ROI) of image serials. The long period application of this method demonstrated that this DQA protocol can reflect imaging performance and the state of stability of the MRI scanner. Some application experience and discussion involved in DQA were also presented here.

Objective:To investigate the clinical, pathological and genetic features of 3 cases of limb-girdle muscular dystrophy 2A (LGMD2A) caused by non-canonical splice site mutations in the CAPN3 gene. Methods:For the 3 LGMD2A patients admitted to Qilu Hospital of Shandong University from July 2016 to July 2018 were selected as the subjects. Clinical data were collected, whole exome sequencing was conducted, and the candidate variants were verified by Sanger sequencing. Total RNA was extracted from the skeletal muscle tissue of 3 probands and effects of splicing mutations on pre-mRNA splicing in the CAPN3 gene were verified by reverse-transcription polymerase chain reaction. Total protein was extracted from the muscle tissue of the probands and expression level of calpain 3 protein was detected by Western blotting. Results:All the 3 probands presented muscle weakness in upper and lower limbs, and muscle weakness in proximal limbs was more severe. Muscle biopsies all indicated myogenic impairment. Genetic sequencing showed proband 1 carried compound heterozygous c.2185-14T>G and c.2305C>T (p.R769W) mutations in the CAPN3 gene, proband 2 carried compound heterozygous c.1193+30G>A and c.2069_2070delAC (p.H690Rfs *9) mutations, and proband 3 carried homozygous c.1194-9A>G mutations in the CAPN3 gene. Splicing assay showed the c.2185-14T>G mutation located in intron 20 induced retention of the entire intron 20, the c.1193+30G>A mutation in intron 9 induced retention of the first 31 nucleotides of intron 9, and the c.1194-9A>G mutation in intron 9 induced retention of the last eight nucleotides of intron 9. Western blotting revealed deficiency of calpain 3 protein in skeletal muscle of proband 1 and proband 2. Conclusions:The clinical manifestation of LGMD2A is muscle weakness predominantly in proximal limbs, and the muscle pathology is mostly characterized by myogenic impairment.Moreover, aberrant splicing of pre-mRNA caused by non-canonical splice site mutations plays a pathogenic role in this disease.

Objective:To discuss the clinical characteristics of autosomal recessive spinocerebellar ataxia type 16 patients caused by STUB1 gene mutation, in order to improve the clinical doctors′ understanding of the disease. Methods:The clinical manifestations, auxiliary examinations and genetic testing of 1 autosomal recessive spinocerebellar ataxia type 16 patient caused by STUB1 gene variants diagnosed in Qilu Hospital of Shandong University in May 2022 were collected, and the relevant literature was reviewed to summarize the clinical and genetic characteristics of this type of disease. Results:The proband was a 35-year-old male presenting with unsteady walk and dysarthria. Magnetic resonance imaging showed cerebellar atrophy. Next generation sequencing revealed compound heterozygous c.322dupG (p.Glu108Glyfs *4) and c.433A>C (p.Lys145Gln) variants in the STUB1 gene (according to the transcript NM_005861.4), and the c.322dupG (p.Glu108Glyfs *4) variant was a novel variant. Pedigree verification revealed the 2 variants were respectively inherited from the proband′s healthy parents. A total of 12 foreign literatures reported 32 autosomal recessive spinocerebellar ataxia type 16 patients. The main clinical manifestations were ataxia, dysarthria and tendon hyperreflexia. Besides, nystagmus, spasticity, action tremors, and myoclonus can be present. Magnetic resonance imaging predominantly showed cerebellar atrophy. Conclusions:The patient with autosomal recessive spinocerebellar ataxia type 16 caused by STUB1 gene variant is rare in China. The main clinical manifestation is cerebellar ataxia, and brain imaging reveals remarkable cerebellar atrophy. Genetic testing is helpful for definite diagnosis.

Objective:To characterize limb traumatic osteomyelitis in a regional trauma center in South China.Methods:The case system at Division of Orthopaedics and Traumatology, Department of Orthopaedics, Nanfang Hospital was searched for the data of confirmed limb traumatic osteomyelitis from January 1, 2010 through September 1, 2019. The clinical items collected were gender, age of onset, cause of injury, injury nature (open or closed), infected site (single site or multiple sites), intraoperative culture of pathogenic microorganisms, number and type of pathogenic microorganisms, and amputation. The above data were sorted out and analyzed statistically.Results:A total of 674 patients suffered limb traumatic osteomyelitis in South China with a male to female ratio of 4.81∶ 1. The limb traumatic osteomyelitis resulted mainly from open injury (64.09%, 432/674). It was mainly caused by a traffic accident (39.51%, 211/534). It was featured by single-site infection (83.68%, 564/674). It affected mainly the lower limbs: the tibia (53.19%, 300/564), the femur (18.97%, 107/564), the calcaneus (11.70%, 66/564) and other foot bones (4.61%, 26/564). The positive rate of intraoperative microorganisms culture was 65.26% (355/544). In the majority of patients (74.65%, 265/355), the traumatic osteomyelitis was caused by infection of a single pathogenic microorganism. The most common single pathogenic microorganism was Staphylococcus aureus (38.11%, 101/265), followed by Pseudomonas aeruginosa (20.00%, 53/265). The rate of amputation related to traumatic osteomyelitis was 3.71% (25/674), and the overall disability rate was 4.45% (30/674).Conclusions:In South China, more males were prone to limb traumatic osteomyelitis. Most cases were secondary to an open fracture and caused by a traffic accident. Traumatic osteomyelitis usually occurred at a lower limb. The most common pathogenic microorganism was Staphylococcus aureus.
