Mutations in CERS3 Gene Underlies a Case of Autosomal Recessive Congenital Ichthyosis / 罕见病研究

Autosomal recessive congenital ichthyosis caused by CERS3 mutations is extremely rare in clinical practice. We recently identified a family of autosomal recessive congenital ichthyosis and performed multigene exome sequencing for hereditary skin diseases to identify causative genes. Mutation analysis revealed compound heterozygous mutations of c.746A>G(from the mother) and exon12 deletion(from the father)in CERS3 were detected in the proband, which were verified by Sanger sequencing and co-segregated with the ichthyosis phenotype in the proband and her parents. These mutations were both reported for the first time. For the treatment, the proband received an oral acitretin capsules of 20 mg once daily. After 3-month follow up, the patient's lesion improved significantly.

The non-communicating intracranial-extracranial Rosai-Dorfman disease: a case report / 中华神经科杂志

Rosai-Dorfman disease (RDD) is a benign self-limited disease characterized by lymphadenopathy and phagocytosis of lymphocytes by histiocytes. A case of intracranial-extracranial non communicating RDD was reported in this paper. The patient was admitted to Shiyan Taihe Hospital in May 2020 because of "the left top scalp tumor was found for 4 months, and the right lower limb was numb for more than half a month". The plain scan and enhanced scan of the patient′s head magnetic resonance imaging (MRI) showed that the disease focus of the left parietal bone was slightly uneven enhanced, its internal and external soft tissues were significantly enhanced, and the local internal and external soft tissues were significantly thickened irregularly, with the size of about 3.2 cm× 4.7 cm, and adjacent brain parenchyma was compressed. After resection of left top mass and intracranial mass, pathological results showed spindle cell proliferation with inflammatory reaction, and immunohistochemical staining results supported the diagnosis of RDD. The neurological function of the patient recovered to normal basically 7 months after operation, and no recurrence of the disease was found in the MRI examination of the head. The treatment effect was satisfactory.

Mutation analysis of the PNPLA1 gene in three families with congenital ichthyosiform erythroderma / 中华皮肤科杂志

Objective:To detect gene mutations in 3 Chinese families with congenital ichthyosiform erythroderma.Methods:Exome sequencing of peripheral blood DNA was performed for 3 probands clinically diagnosed with congenital ichthyosiform erythroderma by using a gene panel targeting hereditary skin diseases to identify mutation sites. Primers were designed according to the mutation sites for PCR amplification, and Sanger sequencing was performed to verify the mutations in probands and other family members in order to identify the cause of the disease.Results:The probands 1 and 2 presented with generalized skin dryness and scaling, and polygonal dark brown scales on the extensor aspect of the lower limbs; the proband 3 mainly presented with well-circumscribed erythema, papules and scales scattered on the trunk and extremities. All probands denied family history of similar diseases. Genetic testing showed that the proband 1 carried compound heterozygous mutations c.100G>A and c.377G>A in the PNPLA1 gene, which were inherited from her mother and father respectively; the proband 2 carried compound heterozygous mutations c.320T>A and c.434T>C in the PNPLA1 gene, which were inherited from her mother and father respectively; a homozygous mutation c.1300delG was identified in the PNPLA1 gene in the proband 3. The mutations co-segregated with the disease phenotypes in the two families with compound heterozygous mutations. Among the 5 identified mutations, the two missense mutations (c.377G>A and c.320T>A) were firstly reported.Conclusion:Biallelic mutations in the PNPLA1 gene are the causative mutations responsible for autosomal recessive congenital ichthyosis in the three probands, and the newly reported mutations expand the mutation spectrum in the disease.

A case of ADULT syndrome without finger/toe deformities caused by a TP63 mutation / 中华皮肤科杂志

Objective:To detect causative gene mutations in 1 patient with ADULT syndrome mainly presenting with ectodermal dysplasia.Methods:Clinical data were collected from a proband with ADULT syndrome, and genomic DNA was extracted from peripheral blood samples obtained from the proband and his parents. Exome sequencing was performed in the proband by using targeted panels for hereditary skin diseases to determine mutation sites, and then the candidate mutation sites were verified by Sanger sequencing in the family members.Results:The 22-year-old male patient presented with sparse and thin hair, scattered facial freckles, missing permanent teeth, cloudy corneas, palmoplantar erythema and keratosis, nail/toenail dystrophy, and nipple dysplasia. Genetic testing of the peripheral blood genomic DNA of the proband revealed a heterozygous mutation (c.1040G>T) in exon 8 of the TP63 gene, resulting in an amino acid change at position 347 (p.C347F) . The mutation was not detected in his father or mother with normal phenotypes, suggesting the cosegregation of the gene mutation with the disease phenotype in the family.Conclusion:The de novo heterozygous missense mutation in the TP63 gene may be the causative mutation in the proband, and combined with clinical manifestations, the proband was diagnosed with ADULT syndrome without finger/toe deformities.

Chinese expert consensus on diagnosis, treatment and prevention of venous thrombus embolism associated with chest trauma (2022 version) / 中华创伤杂志

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.

Effects of simulated weightlessness on biomechanics of motion unit of rhesus monkey lumbar vertebra / 中国组织工程研究

BACKGROUND:It is generaly believed that the spine wil be extended, and vertebral muscle atrophy, bone loss of vertebral body, increased height and area of intervertebral disc, changes of composition of intervertebral disc wil occur in the condition of weightlessness. These are likely to be the cause of high incidence of low back pain. OBJECTIVE:To observe changes in lumbar spine bone microstructure analysis of simulated weightlessness on rhesus lumbar spine biomechanics. METHODS:Fourteen young rhesus monkeys were randomly divided into two groups: control group (n=7;free activities in the cage during the experiment), and experimental group (n=7; the use of head-down-10° on a special bed by bundle lying to simulate weightlessness). RESULTS AND CONCLUSION:(1) The results of Micro-CT examination: in the experimental group, structure model index in trabecular bone of increased. Trabecular bone changed from plate-like to the rod-like change. The intersection number of bone tissue in unit length to non-bone tissue declined. The average width of the canal between the trabecular bone increased, suggesting that there have been signs of osteoporosis in the experimental group. (2) Under an optical microscope, in the experimental group, bone hyperplasia line was disordered and irregular. Thick endplate trabecularbone became smal, shalow, and arranged substantialy perpendicular to the direction of trabecular bone and cartilage endplate. The closer the endplate surface, the smaler trabecular bone was. Compared with the control group, these smal trabecular bones were thin and curved. Bone marrow cavity was oval. The degree of the connection between the trabecular bones is poor, reflecting the structural characteristics of significant osteoporosis. (3) It is indicated that weightlessness affected the biomechanical properties of rhesus lumbar motion unit.

OBJECTIVE:To establish the detection method for pyrogen-related factor interleukin 1β(IL-1β)through optimiz-ing detection condition,and to conduct preliminary methodology study. METHODS:The in vitro fresh human whole blood detec-tion method was used. The bacterial endotoxin standard solution(5,2,0.8,0.32 EU/ml)were added into diluted blood;using di-luted RPMI 1640 as blank control,the content of IL-1β in blood sample was determined by ELISA after incubation. The relation-ship of the addition of different attenuants(RPMI 1640 culture,sterilized normal saline)and fetal bovine serum,final dilution vol-ume fraction(40%,20%,10%and 8.3%)and storage duration(2,5,6,8,26 h)with the contents of endotoxin IL-1βwere in-vestigated,and related coefficient and detection limits were calculated. Different dilution times of Qingkailing injection and Ginaton injection samples and interference solutions were added into diluted blood to detect their recovery. RESULTS:The results indicated that RPMI 1640 media and 40% diluted blood was more sensitive(detection limit was 0.128 EU/ml,r=0.993);while the addition of fetal bovine serum didn’t influence the results. The detection limits of blood sample storied at 4 ℃ for 26 h were 0.128 EU/ml (r>0.990). When Qingkailing injection and Ginaton injection were diluted 10,32 and more times,the detection method was not interfered and the recovery ranged 68%-118%. CONCLUSIONS:Established in vitro fresh human whole blood detection method can be used for the detection of pyrogen,and provides trial evidence for the pyrogen detection of TCM injection.
