A case report of a Filipino boy with childhood cataract and clinically diagnosed Roberts Syndrome

@#Childhood cataract is a common cause of visual impairment. Familial types are uncommon among Filipinos. Furthermore, it is not common to have one that follows an autosomal dominant pattern of inheritance but with associated syndromic presentation like Roberts syndrome which is an autosomal recessive disorder. This is a case of a 9-year-old Filipino boy with cataract in the left eye associated with low-set ears, facial asymmetry, underdeveloped nasal ala, cleft lip and palate, macroglossia, micrognathia, short right shin, and absent feet. Patient was clinically diagnosed with Roberts syndrome. We present a clinically diagnosed Roberts syndrome (RS), the first reported RS in a Filipino in local and international literature to our knowledge with an autosomal dominant childhood cataract. Genetic testing can assist in the confirmation of this case.

Splicing mutations of GSDME cause late-onset non-syndromic hearing loss / 临床耳鼻咽喉头颈外科杂志

Objective:To dentify the genetic and audiological characteristics of families affected by late-onset hearing loss due to GSDMEgene mutations, aiming to explore clinical characteristics and pathogenic mechanisms for providing genetic counseling and intervention guidance. Methods:Six families with late-onset hearing loss from the Chinese Deafness Genome Project were included. Audiological tests, including pure-tone audiometry, acoustic immittance, speech recognition scores, auditory brainstem response, and distortion product otoacoustic emission, were applied to evaluate the hearing levels of patients. Combining with medical history and physical examination to analyze the phenotypic differences between the probands and their family members. Next-generation sequencing was used to identify pathogenic genes in probands, and validations were performed on their relatives by Sanger sequencing. Pathogenicity analysis was performed according to the American College of Medical Genetics and Genomics Guidelines. Meanwhile, the pathogenic mechanisms of GSDME-related hearing loss were explored combining with domestic and international research progress. Results:Among the six families with late-onset hearing loss, a total of 30 individuals performed hearing loss. The onset of hearing loss in these families ranged from 10 to 50 years（mean age: 27.88±9.74 years）. In the study, four splicing mutations of the GSDME were identified, including two novel variants: c. 991－7C>G and c. 1183+1G>T. Significantly, the c. 991－7C>G was a de novo variant. The others were previously reported variants: c. 991-1G>C and c. 991-15_991-13del, the latter was identified in three families. Genotype-phenotype correlation analysis revealed that probands with the c. 991－7C>G and c. 1183+1G>T performed a predominantly high-frequency hearing loss. The three families carrying the same mutation exhibited varying degrees of hearing loss, with an annual rate of hearing deterioration exceeding 0.94 dB HL/year. Furthermore, follow-up of interventions showed that four of six probands received intervention（66.67%）, but the results of intervention varied. Conclusion:The study analyzed six families with late-onset non-syndromic hearing loss linked to GSDME mutations, identifying four splicing variants. Notably, c. 991－7C>G is the first reported de novo variant of GSDME globally. Audiological analysis revealed that the age of onset generally exceeded 10 years,with variable effectiveness of interventions.

Cell dispersion was below average in May for Cyanophyceae, Bacillariophyceae, Cryptophyceae, and Synurophyceae. Oscillatoria, Monoraphidium, Actinastrum, Cosmarium, Trachelomonas, and Euglena dominated the surveyed region. The Shannon Diversity Index showed a value of 1.51, while Simpson's Diversity Index showed a value of 0.28. The overall variation (80.73%) among the classes was represented by PCA cells. According to the Shannon and Simpson Diversity Indexes, the diversity was low.

Advances in the regulation of autosomal dominant polycystic kidney disease by Hippo signaling pathway / 中华肾脏病杂志

The Hippo signaling pathway is highly conserved in evolution, and participates in the regulation of cell proliferation, differentiation, and tissular dynamic balance, and plays an important role in regulating tissue, organ size, and cell number. Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease and one of the most common causes of end-stage renal disease. Emerging studies have identified the Hippo signaling pathway is closely related to the occurrence and development of ADPKD. The abnormal activity and expression of the main members of the pathway affect the cilia and cell polarity of renal tubular epithelial cells and induce the formation of renal cysts. The review summarizes the potential mechanism of the Hippo pathway in the pathogenesis of ADPKD, the crosstalk with other signaling pathways, and the variances in different species, and discusses the strategies for the treatment of ADPKD based on the Hippo signaling pathway to provide new strategies for the treatment.

Deciphering the pathogenicity of COL4A4 heterozygous splicing mutations and the genotype-phenotype correlation in autosomal dominant Alport syndrome / 中华肾脏病杂志

Objective:Through the investigation of the pathogenicity of COL4A4 heterozygous splicing mutations and the genotype-phenotype correlation in autosomal dominant Alport syndrome (ADAS), to better understand the impact of COL4A4 heterozygous splicing mutations on ADAS. Methods:The study was a case series analysis. Patients from 5 ADAS families with COL4A4 heterozygous splicing mutations detected by whole exome sequencing were recruited by three hospitals. In vivo transcriptional analysis and/or in vitro minigene splicing assay were conducted to determine the splicing patterns and assess the pathogenicity of COL4A4 heterozygous splicing mutations. Results:In the five ADAS pedigrees carrying COL4A4 heterozygous splicing mutations, four novel ADAS splicing patterns were described. In pedigree 1-4, most patients presented with continuous hematuria or/and microalbuminuria. Otherwise,the proband in pedigree 4 presented with macroalbuminuria and the proband in pedigree 1 had progressed to chronic kidney disease stage 2 at the age of 70 years old. In pedigree 5, all patients developed end-stage renal disease between 28 and 41 years old. c.735+3A>G detected in pedigree 1 and pedigree 2 and c.694-1G>C detected in pedigree 3 both led to exon 12 skipping in COL4A4, resulting in 42 nucleotides in-frame deletion (c.694_735del). c.2056+3A>G detected in pedigree 4 led to COL4A4 exon 26 skipping, which caused in-frame deletion of 69 nucleotides (c.1988_2056del). c.2716+5G>T detected in pedigree 5 led to a 360 nucleotides large in-frame deletion, including 100 bp sequence at the 3'end of exon 29,the whole sequence of exon 30 and 89 bp sequence at the 5'end of exon 31 (c.2446_2805del). Conclusions:Renal prognosis differs significantly for patients with small in-frame deletions versus large in-frame deletion splicing abnormalities. Determination of the pathogenicity and the splicing patterns of COL4A4 heterozygous splicing mutations using in vivo and in vitro transcriptional analysis may provide renal prognostic information.

Clinical technical operation specification of kidney transplantation for autosomal dominant polycystic kidney disease (2022 edition) / 器官移植

Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited kidney disease and one of the most common causes for end-stage renal disease (ESRD). Kidney transplantation is the optimal renal replacement therapy for ADPKD patients complicated with ESRD. Currently, scholars at home and abroad have a certain controversy about whether polycystic kidney resection is necessary in ADPKD patients before kidney transplantation, and the criteria and methods for polycystic nephrectomy also differ. To further standardize the clinical technical operation of kidney transplantation in ADPKD patients, experts in organ transplantation organized by Branch of Organ Transplantation of Chinese Medical Association formulated this specification from the aspects of diagnosis of ADPKD, indications and contraindications of kidney transplantation for ADPKD, preoperative evaluation and treatment, polycystic nephrectomy, and postoperative management, etc.

Comparative Study of the Distal Transverse Arch of the Hand Between the Dominant and Non-Dominant Hands and By Age and Sex / The Japanese Journal of Rehabilitation Medicine

Introduction：The range of motion (ROM) of the distal transverse arch of the hand has not been established and cleared sufficiently.Purpose：The aim of this study was to clarify the differences in the distal transverse arch of the hand in ROM between the dominant and non-dominant hands and by sex and age.Participants：We enrolled 118 healthy participants aged 20-69 years.Results：The average active and passive ROMs of the distal transverse arch of the hand were 135.4° ± 10.3°/168.9° ± 12.1° on the dominant side and 131.8° ± 9.8°/166.9° ± 13.2° on the non-dominant side. Active and passive ROMs were significantly larger on the dominant side than on the non-dominant side (p＜0.001, p＝0.009). The active or passive ROM of the distal transverse arch of the hand on either side did not differ significantly between men and women. However, the ROM of the ring finger component was significantly larger in women than in men on both sides (p＝0.02～0.003). The active and passive ROMs of the distal transverse arch in both hands were significantly smaller in participants aged over 60 years than in those aged up to 60 years (p＜0.05). Moreover, compared to participants in their 20s, participants in their 30s and 40s showed lower passive ROMs of the dominant hand and little finger component of the transversal arch in both hands (p＜0.05).Discussion：Our results suggested that handedness, sex, and age should be considered when managing the distal transverse arch of the hand.

Clinical value-oriented research paradigm about inheritance and innovation development of TCM dominant diseases / 中草药·英文版

Modern medicine has made remarkable achievements in safeguarding people's life and health, however, it is increasingly found that in the face of complex diseases, selective targeting of single target is often difficult to produce a comprehensive rehabilitation effect, and is prone to induce drug resistance, toxic side effects. Traditional Chinese medicine (TCM) has a long history of clinical application, and its clinical value in the treatment of complex diseases such as cardiovascular and cerebrovascular diseases, digestive diseases, skin diseases, rheumatism and immunity diseases, and adjuvant treatment of tumors has been proven to have obvious advantages. However, its modern research is relatively lagging behind, and in the face of the aging society and the characteristics of the modern disease spectrum, the traditional knowledge-driven research paradigm seems to be stuck in a bottleneck and difficult to make greater breakthroughs. Focusing on the key issues of TCM development in the new era, the clinical value-oriented strategy becomes to be a new research paradigm of TCM inheritance and innovation development, and dominant diseases would be the focus of the TCM inheritance and innovation development, which has been highly valued in recent years by the TCM academia and the relevant national management departments. Based on the clinical value, a series of policies are formulated for the selection and evaluation of the TCM dominant diseases (TCMDD), and exploratory researches about the clinical efficacy characteristics, the modern scientific connotation interpretation were carried out. The clinical value-oriented research paradigm of TCMDD inheritance and innovation development has been initially formed, which is characterized by strong policy support as the guarantee, systematic and standardized selection and evaluation methods as the driving force, scientific and effective research on internal mechanisms as the expansion, and effective clinical guidelines and principles as the transformation, which is of great value in promoting the high-quality development of the industries and undertaking of TCM. In this paper, the main policy support, selection and evaluation methods, therapeutic effect characterization, and modern scientific connotation research strategies of TCMDD in recent years have been comprehensively sorted out, with a view to providing the healthy and benign development of the research on TCMDD.

Pharmacodynamic advantages and characteristics of traditional Chinese medicine in prevention and treatment of ischemic stroke / 中草药·英文版

Ischemic stroke (IS) is a severe cerebrovascular disease with a high incidence, mortality, and disability rate. The first-line treatment for IS is the use of recombinant tissue plasminogen activator (r-tPA). Regrettably, numerous patients encounter delays in treatment due to the narrow therapeutic window and the associated risk of hemorrhage. Traditional Chinese medicine (TCM) has exhibited distinct advantages in preventing and treating IS. TCM enhances cerebral microcirculation, alleviates neurological disorders, regulates energy metabolism, mitigates inflammation, reduces oxidative stress injuries, and inhibits apoptosis, thereby mitigating brain damage and preventing IS recurrence. This article summarizes the etiology, pathogenesis, therapeutic strategies, and relationship with modern biology of IS from the perspective of TCM, describes the advantages of TCM in the treatment of IS, and further reviews the pharmacodynamic characteristics and advantages of TCM in the acute and recovery phases of IS as well as in post-stroke complications. Additionally, it offers valuable insights and references for the clinical application of TCM in IS prevention and treatment, as well as for the development of novel drugs.

Treatment of Allergic Rhinitis with Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

This article reviews the clinical studies about the treatment of allergic rhinitis （AR） with traditional Chinese medicine （TCM） in recent years. AR is a common and frequently occurring disease in the department of otolaryngology. The common manifestations of AR include nasal congestion， sneezing， runny nose， and nasal itching. AR， belonging to the category of rhinitis， is a dominant disease in the TCM treatment of otorhinolaryngologic diseases and head and neck diseases. The ancient literature has laid a solid theoretical basis on the etiology and pathogenesis of AR. According to the ancient literature， the theoretical basis， and their own experience， modern doctors classified the causes of AR into the disorders in Zang-fu organs and six meridians. Most of the explanations focus on the disorders in Zang-fu organs， especially the lung， spleen， and kidney. The clinical studies in this field mainly involve TCM treatment alone， integrated TCM and Western medicine treatment， and TCM external treatment. These therapies have good efficacy in the clinical treatment of AR. Among them， TCM treatment alone has significant advantages in alleviating the symptoms and nasal signs， declining the scores of related scales， and reducing the eosinophil count （EOS） of nasal secretions， with definite long-term efficacy. Integrated TCM and Western medicine treatment can complement with each other. The TCM external treatment methods include acupuncture， moxibustion， acupoint catgut embedding， acupoint application， and nasal irrigation with TCM， which are safe， simple， acceptable by patients and have good therapeutic effect. Finally， the clinical research status of TCM treatment of AR was summarized， and suggestions were put forward from three aspects： standardizing the clinical research protocol of TCM， encouraging pure TCM research， and exploring the mechanism of TCM treatment on the basis of frontier research achievements. This review aims to provide higher-level evidence for subsequent clinical research and promote the research on dominant AR diseases.

Expert Consensus on Clinical Diseases Responding Specifically to Traditional Chinese Medicine： Sjögren's Syndrome / 中国实验方剂学杂志

Sjögren's syndrome （SS）， a disorder of immune system， is one of the dominant diseases treated by traditional Chinese medicine （TCM）. China Association of Chinese Medicine organized experts in the field of TCM and western medicine rheumatology and pharmacology to discuss the advantages and optimal regimens of TCM for the treatment of SS. The experts generally agreed on the low early diagnosis rate of SS and the lack of targeted therapeutic drugs. In addition， autoimmune abnormality is the key factor in the occurrence of SS and deficiency of both Qi and Yin is the core pathogenesis. SS has unique tongue manifestations， which is expected to allow for the early diagnosis and treatment with integrated traditional Chinese and western medicine. TCM has advantages in treating SS in terms of alleviating clinical symptoms and systemic involvement， individualized treatment， relieving sleep and mood disorders， preventing the occurrence in the early stage， and enhancing the effectiveness and reducing toxicity in the treatment by integrated TCM and western medicine. In general， TCM has advantages in different stages of SS. Internal and external use of TCM， acupuncture， and acupotome are all available options. The optimal regimens should be determined on the basis of pattern identification， stage of disease， and the advantages of TCM. Clinical characteristics and biomarkers of SS should be studied to classify patients， so as to design precision evidence-based TCM regimens for SS. On the basis of unique tongue manifestations of SS， models for early diagnosis and poor prognosis identification of SS should also be established to achieve early prevention and treatment and to improve the prognosis. In the future， we should vigorously carry out high-quality evidence-based medical research on the treatment of SS by TCM and integrated traditional Chinese and western medicine and develop relevant guidelines to optimize and standardize current diagnosis and treatment， thereby laying a basis for clarifying and explaining the advantages of TCM in treating SS.

Variation and interaction mechanism between active components in Rheum officinale and rhizosphere soil microorganisms under drought stress / 中国中药杂志

To explore the changes and the reaction mechanisms between soil microecological environment and the content of secon-dary metabolites of plants under water deficit, this study carried out a pot experiment on the 3-leaf stage seedlings of Rheum officinale to analyze their response mechanism under different drought gradients(normal water supply, mild, moderate, and severe drought). The results indicated that the content of flavonoids, phenols, terpenoids, and alkaloids in the root of R. officinale varied greatly under drought stresses. Under mild drought stress, the content of substances mentioned above was comparatively high, and the content of rutin, emodin, gallic acid, and(+)-catechin hydrate in the root significantly increased. The content of rutin, emodin, and gallic acid under severe drought stress was significantly lower than that under normal water supply. The number of species, Shannon diversity index, richness index, and Simpson index of bacteria in the rhizosphere soil were significantly higher than those in blank soil, and the number of microbial species and richness index decreased significantly with the aggravation of drought stresses. In the context of water deficit, Cyanophyta, Firmicutes, Actinobacteria, Chloroflexi, Gemmatimonadetes, Streptomyces, and Actinomyces were the dominant bacteria in the rhizosphere of R. officinale. The relative content of rutin and emodin in the root of R. officinale was positively correlated with the relative abundance of Cyanophyta and Firmicutes, and the relative content of(+)-catechin hydrate and(-)-epicatechin gallate was positively correlated with the relative abundance of Bacteroidetes and Firmicutes. In conclusion, appropriate drought stress can increase the content of secondary metabolites of R. officinale from physiological induction and the increase in the association with beneficial microbe.

Correlation of gut dominant microbiota with hyperuricemia / 浙江大学学报·医学版

OBJECTIVES@#To study the correlation of intestinal dominant flora with hyperuricemia, and to explore influencing factors of hyperuricemia.@*METHODS@#Data of gut dominant microbiota were collected from subjects who underwent health check-up in Shulan (Hangzhou) Hospital from January 2018 to April 2020. Subjects with high uric acid and normal uric acid were matched by propensity score matching method according to age, gender and body mass index (BMI). This resulted in 178 pairs as hyperuricemia group and control group. The gut dominant microbiota between hyperuricemia and normal control group were compared. Pearson or Spearman correlation coefficient method was used to analyze the correlation between blood uric acid and intestinal dominant flora. Univariate and multivariate logistic regression were used to analyze the influencing factors of hyperuricemia.@*RESULTS@#The abundance of Atopobium, Lactobacillus, Bacteroides, Enterococcus, Clostridium leptum, Fusobacterium prausnitzii, Bifidobacterium, Clostridium butyricum and the ratio of Bifidobacterium to Enterobacter (B/E) in the hyperuricemia group were significantly lower than those in the control group (all P<0.01). The correlation analysis showed that serum uric acid were negatively correlated with the abundance of Atopobium (r=－0.224, P<0.01), Bacteroides (r=－0.116, P<0.05), Clostridium leptum (r=－0.196, P<0.01), Fusobacterium prausnitzii (r=－0.244, P<0.01), Bifidobacterium (r=－0.237, P<0.01), Eubacterium rectale (r=－0.125, P<0.05), Clostridium butyricum (r=－0.176, P<0.01) and B/E value (r=－0.127, P<0.05). Multivariate logistic regression analysis showed that glutamyl transpeptidase was an independent risk factor for hyperuricemia (OR=1.007, 95%CI: 1.002-1.012, P<0.05), and the Atopobium was an independent protective factor for hyperuricemia (OR=0.714, 95%CI: 0.605-0.842, P<0.01).@*CONCLUSIONS@#There are alterations in abundance of gut dominant microbiota in patients with hyperuricemia, and Atopobium abundance appears as a protective factor for hyperuricemia.

Combined liver-kidney transplant in polycystic diseases: a case report

ABSTRACT Polycystic liver disease, a hereditary pathology, usually manifests as autosomal dominant polycystic kidney disease. The many cysts in the liver cause massive hepatomegaly, majorly affecting the patient's quality of life. In cases of refractory symptoms, liver transplantation is the only treatment choice. A 43-year-old woman was followed up as a hepatology outpatient in August 2020, with a progressive increase in abdominal volume, lower limb edema, and cachexia. The patient was diagnosed with polycystic renal and liver disease with massive hepatomegaly in March 2021, a combined kidney-liver transplant. Liver size represented 13% of the patient's corporal composition, weighing 8.6kg. The patient was discharged on the 7th postoperative day with no complications. Only 10-20% of patients with polycystic liver disease have clinical manifestations, most of which result from hepatomegaly. An increase in liver volume deteriorates liver function until the condition becomes end-stage liver disease, as kidney function is already compromised; liver-kidney transplantation remains the only treatment choice. The case described drew significant attention to the massive hepatomegaly presented in the patient, with the liver representing over 10% of the patient's body weight, approximately five to six times larger than a normal-sized liver.

Association between Facial Types and Handedness among Students of Faculty of Basic Medical Sciences Bayero University, Kano

Background: Generally, a person's dominant hand is a simple and precise determinant of his preference for hand use in fine manual tasks. The main tools used in forensics are derived from the relationships between anthropometric features with important physical and /or biological traits. Objective: This study was to determine the association between facial types and handedness among students of the Faculty of Basic Medical Sciences of Bayero University, Kano. Methodology: Cross-sectional study design with a consecutive sampling of 400 (180 males and 220 females) students (aged 18 and above) of the Faculty of Basic Medical Sciences Bayero University, Kano was carried out. Facial height (FH) and facial width (FW) were measured using established landmarks and the facial index (FI) was calculated from them. The dominant handedness of each participant was determined using the writing component of the Edinburgh Handedness Inventory. This procedure involved asking the participants to mention which of their hands was dominant. The participant was then asked to write a sentence regarding the activitieshe/she was carrying out at the point of recruitment to ascertain the claim made by the participants. The sentence was written separately using each hand. All the data obtained were analyzed using statistical software (SPSS version 20.0). Results: The study population was relatively young (21.76 ± 2.77 years). Right-handedness was the commonest hand dominance observed in both males (90.7%) and females (91.7%). The commonest types of face were the hypereuriproscopic 2 (0.5%), Euriproscopic 41 (10.3%), Mesoproscopic 78 (19.5%), Leptoproscopic 127 (31.8%) and Hyperleptoproscopic 152 (37%) facial types. The majority of the participants were right-handed and this was regardless of gender. The prediction of handedness based on facial types (ꭕ2 = 1.39, Df =3, P = 0.85) or facial index (P = 0.92, OR=0.99, CI = 0.82 ­ 1.19) was not statistically significant. Conclusion: The facial types identified among the study population were not associated with their handedness and thus it was not a good predictor of handedness

Autosomal dominant neurodevelopmental disorders associated with KIF1A gene variants in 6 pediatric patients / 浙江大学学报·医学版

OBJECTIVES@#To analyze the clinical and genetic characteristics of children with autosomal dominant neurodevelopmental disorders caused by kinesin family member 1A (KIF1A) gene variation.@*METHODS@#Clinical and genetic testing data of 6 children with KIF1A gene de novo heterozygous variation diagnosed in Shanghai Children's Medical Center Affiliated to Shanghai Jiao Tong University School of Medicine from the year 2018 to 2020 were retrospectively analyzed. Pathogenic variants were identified based on whole exome sequencing, and verified by Sanger sequencing. Moreover, the effect of variants on three-dimensional structure and stability of protein was analyzed by bioinformatics.@*RESULTS@#Among 6 patients there were 4 males and 2 females, and the age of consultation varied from 7 months to 18 years. All cases had varying degrees of motor developmental delay since childhood, and 4 of them had gait abnormalities or fell easily. In addition, 2 children were accompanied by delayed mental development, epilepsy and abnormal eye development. Genetic tests showed that all 6 cases had heterozygous de novo variations of KIF1A gene, including 4 missense mutations c.296C>T (p.T99M), c.761G>A (p.R254Q), c.326G>T (p.G109V), c.745C>G (p.L249V) and one splicing mutation c.798+1G>A, among which the last three variants have not been previously reported. Bioinformatics analysis showed that G109V and L249V may impair their interaction with the neighboring amino acid residues, thereby impacting protein function and reducing protein stability, and were assessed as "likely pathogenic". Meanwhile, c.798+1G>A may damage an alpha helix in the motor domain of the KIF1A protein, and was assessed as "likely pathogenic".@*CONCLUSIONS@#KIF1A-associated neurological diseases are clinically heterogeneous, with motor developmental delay and abnormal gait often being the most common clinical features. The clinical symptoms in T99M carriers are more severe, while those in R254Q carriers are relatively mild.
