Objective:To analyze the clinical characteristics, muscle imaging and pathological features of patients with anti-signal recognition particle positive immune-mediated necrotizing myopathy (SRP-IMNM).Methods:Nine patients with SRP-IMNM were collected in the Neuromuscular Disease Center of Jiaozuo People′s Hospital from May 2018 to May 2023, who were confirmed by skeletal muscle pathology and myositis-specific autoantibodies detection, and their clinical manifestations, muscle imaging and muscle pathology characteristics were systematically summarized.Results:Among the 9 patients with SRP-IMNM, there were 7 females and 2 males. The age of onset ranged from 18 to 59 years. All the patients presented proximal muscle weakness. Seven patients experienced neck weakness, and dysphagia was present in 5 patients. Laboratory examinations showed elevated serum creatine kinase levels in all 9 patients (1 866-6 725 U/L). Eight patients were combined with other antibodies positivity, except for anti-SRP antibody. Among them, 7 patients were combined with anti-Ro-52 antibody positivity, 4 patients combined with anti-Ro-52 antibody positivity alone, and 3 patients combined with 3 or more positive antibodies simultaneously. Those patients who presented with interstitial lung disease and cardiac involvement were all combined with other antibodies positivity. Seven patients completed thigh muscle magnetic resonance imaging (MRI), which showed diffuse skeletal muscle oedema, partial muscle atrophy and fatty replacement, primarily affecting the posterior thigh muscle group. Two patients underwent shank muscle MRI. The soleus involvement was evident, while the tibialis anterior muscle and gastrocnemius muscles were involved in 1 patient. All 9 patients showed varying degrees of scattered muscle fiber necrosis and regeneration on muscle biopsies. In 1 patient, a small amount of inflammatory cell infiltration was observed. Pipestem capillaries were observed in 4 patients. Immunohistochemical staining revealed a small number of CD68-positive lymphocytes in 8 patients. Additionally, 5 patients showed upregulation of major histocompatibility complex Ⅰ expression on the muscle fiber membrane, while 6 patients showed deposition of membrane attack complex (C5b-9) on non-necrotic muscle fibers and capillaries. P62 staining showed homogeneous fine-granular in sarcoplasm in 6 patients.Conclusions:In addition to proximal muscle weakness, patients with SRP-IMNM often experience neck weakness and dysphagia. Those with multiple antibodies are more likely to develop interstitial lung disease and cardiac involvement. SRP-IMNM patients have diffuse oedema in the affected muscles, and the posterior thigh muscles are more prone to atrophy and fatty tissue formation. C5b-9 deposition and pipestem capillaries are significant pathological features of SRP-IMNM, which provide additional evidence for clinical diagnosis.

Objective:To summarize the characteristics of clinical, muscle pathology and gene mutation of late-onset reducing body myopathy caused by FHL1 gene mutation, in order to improve clinicians′ understanding of this disorder. Methods:The clinical, muscle pathology and muscle magnetic resonance imaging data of the proband from a family diagnosed as reducing body myopathy in Jiaozuo People′s Hospital in December 2021 were collected. Genetic tests and pedigree verification were conducted on the proband and her son.Results:The proband was a 59-year-old female with progressive, asymmetrical limb weakness and muscular atrophy. Her mother, sister and brother had similar symptoms. Electromyography showed myogenic and neurogenic damage. Muscle magnetic resonance imaging indicated that the lesion mainly involved the posterior muscles of the thigh and calf, as well as the gluteus maximus. The muscle pathology showed eosinophilic granular inclusion bodies and rimmed vacuoles in the muscle fibers of the lesion. The structure of myofibrils was disordered and abnormal protein deposition was observed. The gene sequencing showed the FHL1 gene p.C150S heterozygous variation. Conclusions:Late-onset reducing body myopathy is characterized by progressive asymmetric proximal limb muscle weakness, partially involving distal limb muscles and gluteus maximus. Muscle pathology shows the characteristic pathological changes of many kinds of myofibrillar myopathies. FHL1 gene mutation is an important basis for diagnosis.

Objective:To summarize the clinical, imaging, muscle pathological and gene mutational features of patients with late-onset mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS).Methods:Three patients with late-onset MELAS, admitted to Department of Neurology, Jiaozuo People's Hospital Affiliated of Xinxiang Medical University from January 1997 to December 2021 were chosen; all patients were screened for mitochondrial DNA (mtDNA) and nuclear DNA (nDNA) mutations by second-generation gene sequencing. The clinical, imaging, muscle pathological and gene mutational features of patients with late-onset MELAS were analyzed retrospectively.Results:The main clinical manifestations of these late-onset MELAS patients included stroke-like attacks, headache, hearing and vision loss, cognitive decline and mental disorder. The muscle tension and muscle strength of both upper extremities in these 3 patients were normal. Increased muscle tension and active tendon reflexes, and positive pathological signs in both lower extremities were noted in 2 patients. Head MRI showed abnormal long T1 and long T2 signals in temporal occipital parietal cortex and subcortex in 3 patients, and CT showed calcification in bilateral globus pallidus in 1 patient. Ragged red fibers (RRF) and ragged blue fibers (RBF) were found in the muscle biopsies of 3 patients, and cytochrome oxidase (COX)-negative muscle fibers were found in 2 patients. MT-TL1 gene m.3243A>G mutation was detected in all 3 patients by genetic testing, among which mutation in the blood of 2 patients was 15% and 17%, respectively, and mutation in the muscle tissues of 1 patient was 73%. Conclusion:Muscle pathology indicates high RRF percentage in patients with late-onset MELAS; and m.3243A>G spot mutation is the most common mutation type in late-onset MELAS, and m.3243A>G mutation ratio in muscle tissues is obviously higher than that in blood.

This cross-sectional study aimed to investigate the quality of care of diabetes in Shanghai, China. A total of 173 235 patients with type 2 diabetes in 2017 were included in the analysis. Profiles of risk factors and intermediate outcomes were determined. The patients had a mean age of 66.43 ± 8.12 (standard deviation (SD)) years and a mean diabetes duration of 7.95 ± 5.53 (SD) years. The percentage of patients who achieved the target level for HbA_1c (< 7.0%) was 48.6%. Patients who achieved the target levels for blood pressure (BP) < 130/80 mmHg and low-density lipoprotein-cholesterol (LDL-c) < 2.6 mmol/L reached 17.5% and 34.0%, respectively. A total of 3.8% achieved all three target levels, and the value increased to 6.8% with an adaptation of the BP target level (< 140/90 mmHg) for those over 65 years. Multivariable analysis identified the factors associated with a great likelihood of achieving all three target levels: male, young age, short diabetes duration, low body mass index, macrovascular complications, no microvascular complications, prescribed with lipid-lowering medication, and no prescription of antihypertensive medication. In conclusion, nearly 50% and one-third of the patients with diabetes met the target levels for HbA_1c and LDL-c, respectively, with a low percentage achieving the BP target level. The percentage of patients who achieved all three target levels needs significant improvement.

Objective:To investigate the characteristics of clinical, muscle pathology and gene mutation in patients with nemaline myopathy caused by NEB gene mutation.Methods:The clinical and pathological data of patients with nemaline myopathy caused by NEB gene were collected from Neuromuscular Center of Jiaozuo People′s Hospital from January 1997 to January 2020. The next generation sequencing was preformed to detect NEB gene in all patients, and characteristics of gene mutation were analyzed.Results:Among the 11 patients, there were 8 males and 3 females, and 6 of them came from 2 families. The age of seeing a doctor ranged from 11 to 52 years, the age of onset was from 6 to 23 years, and the course of disease ranged from 5 to 35 years. Neurological examination showed that among the 11 patients, 8 patients had high palatal arch and long face. The muscle tone of both upperlimbs was normal, the tendon reflex was depressed, the proximal muscle strength was grade Ⅲ-Ⅴ, and the distal muscle strength was grade Ⅴ. The muscle tone of both lower extremities was reduced and the tendon reflex was absent. The proximal muscle strength was grade Ⅱ-Ⅳ and the distal muscle strength was grade Ⅲ-Ⅴ. No dysphagia or respiratory muscle involvement was found. Muscle biopsies were performed in 7 of the 11 patients, the pathological changes were muscle fibers of different sizes, circular atrophic muscle fibers and compensatory hypertrophic fibers, and occasionally denatured and necrotic muscle fibers were found. Different degrees of rod aggregation could be seen in all the 7 patients. Electron microscopic examination of 5 patients showed that there was rod aggregation between myofibrils, and most of them were located near the Z band, but no intranuclear rod was found. NEB gene was found in all 11 patients, and a total of 9 different mutation sites were detected, including 8 in exon region and 1 in intron region. Among them, c.21522+3A>G was found in 10 cases, c.1623delT was found in 3 cases and c.17611C>T was found in 3 cases. There was 1 case of c.4417C>T, c.2549delA, c.21065dupA, c.3520G>A, c.20943G>A, c.192G>A respectively.Conclusions:The clinical phenotype of nemaline myopathy caused by NEB gene has great heterogeneity. Muscle pathology shows that rod aggregation is an important basis for the diagnosis of this disease. Mutation c.21522+3A>G in intron is the most common mutation in this group of NEB gene. And the novel mutation sites of NEB gene are respectively c.17611C>T, c.2549delA, c.3520G>A, c.21065dupA, c.20943G>A and c.192G>A.
