Predictors of autosomal dominant polycystic kidney disease progression: a Brazilian single-center cohort / Preditores de progressão da doença renal policística autossômica dominante: uma coorte brasileira de centro único

Abstract Introduction: Identifying risk factors for autosomal dominant polycystic kidney disease (ADPKD) progression is important. However, studies that have evaluated this subject using a Brazilian sample is sparce. Therefore, the aim of this study was to identify risk factors for renal outcomes and death in a Brazilian cohort of ADPKD patients. Methods: Patients had the first medical appointment between January 2002 and December 2014, and were followed up until December 2019. Associations between clinical and laboratory variables with the primary outcome (sustained decrease of at least 57% in the eGFR from baseline, need for dialysis or renal transplantation) and the secondary outcome (death from any cause) were analyzed using a multiple Cox regression model. Among 80 ADPKD patients, those under 18 years, with glomerular filtration rate <30 mL/min/1.73 m2, and/or those with missing data were excluded. There were 70 patients followed. Results: The factors independently associated with the renal outcomes were total kidney length - adjusted Hazard Ratio (HR) with a 95% confidence interval (95% CI): 1.137 (1.057-1.224), glomerular filtration rate - HR (95% CI): 0.970 (0.949-0.992), and serum uric acid level - HR (95% CI): 1.643 (1.118-2.415). Diabetes mellitus - HR (95% CI): 8.115 (1.985-33.180) and glomerular filtration rate - HR (95% CI): 0.957 (0.919-0.997) were associated with the secondary outcome. Conclusions: These findings corroborate the hypothesis that total kidney length, glomerular filtration rate and serum uric acid level may be important prognostic predictors of ADPKD in a Brazilian cohort, which could help to select patients who require closer follow up.

Resumo Introdução: É importante identificar fatores de risco para progressão da doença renal policística autossômica dominante (DRPAD). Entretanto, são escassos os estudos que avaliam esse assunto utilizando amostra brasileira. Portanto, o objetivo deste estudo foi identificar fatores de risco para desfechos renais e óbito em coorte brasileira de pacientes com DRPAD. Métodos: Os pacientes tiveram o primeiro atendimento médico entre janeiro/2002 e dezembro/2014, sendo acompanhados até dezembro/2019. Associações entre variáveis clínicas e laboratoriais com desfecho primário (redução sustentada de pelo menos 57% na TFGe em relação ao valor basal, necessidade de diálise ou transplante renal) e desfecho secundário (óbito por qualquer causa) foram analisadas pelo modelo de regressão múltipla de Cox. Entre 80 pacientes com DRPAD, foram excluídos aqueles menores de 18 anos, com TFG <30 mL/min/1,73 m2 e/ou aqueles com dados ausentes. Foram acompanhados 70 pacientes. Resultados: Fatores independentemente associados aos desfechos renais foram: comprimento renal total - Razão de Risco (HR) ajustada com intervalo de confiança de 95% (IC 95%): 1,137 (1,057-1,224), taxa de filtração glomerular - HR (IC 95%): 0,970 (0,949-0,992) e nível sérico de ácido úrico - HR (IC 95%): 1,643 (1,118-2,415). Diabetes mellitus - HR (IC 95%): 8,115 (1,985-33,180) e TFG - HR (IC 95%): 0,957 (0,919-0,997) foram associados ao desfecho secundário. Conclusões: Esses achados corroboram a hipótese de que comprimento renal total, TFG e nível sérico de ácido úrico podem ser importantes preditores prognósticos de DRPAD em uma coorte brasileira, o que pode ajudar a selecionar pacientes que necessitam de acompanhamento mais próximo.

Theoretical Validation of the Identification of Therapeutic Dominant Stages of Traditional Chinese Medicine Based on Subdivision Model of Disease Course:Taking Premature Ovarian Failure for Example / 广州中医药大学学报

Objective To explore the feasibility and operability in identifying the therapeutic dominant stages of traditional Chinese medicine(TCM)based on subdivision model of disease course.Methods The hierarchical Bayesian model was used to differentiate the disease course of 125 cases of premature ovarian failure(POF),and the disease course of POF were divided into the occult stage,diminished ovarian reserve(DOR)stage,premature ovarian insufficiency(POI)stage,and POF stage.An then the paired sample t-test,Pearson correlation analysis and expert in-depth interview were used for the analysis of the therapeutic effects of TCM for POF at various stages.Results(1)Compared with POF stage,DOR and POI stages were frequently intervened by Chinese patent medicine.(2)In DOR(complicated with POI)stage and POF stage,there was significant difference between the degree of TCM intervention and the therapeutic effect(t =-3.70,P＜0.001).(3)The degree of TCM intervention was positively correlated with treatment outcomes in the DOR stage(r = 0.679,P＜0.001),so did in the POF stage(r = 0.432,P＜0.001),but the correlation in the POF stage was slightly lower than that in the DOR stage.(4)The results of in-depth interviews with experts of TCM gynecology showed that in the concealed phase of POF,the prognosis would be most favorable if TCM regulation and intervention were performed.In the DOR stage and POI stage,treatment with Chinese medicine prescriptions usually brought about better curative effect and prognosis.For the patients at POF stage,the therapeutic effect of TCM depended on the patients'compliance and the treatment course,and the effect was relatively not as good as that of the previous stages.Conclusion In the DOR stage and POF stage,the higher the degree of TCM intervention,the better the prognosis will be achieved for the patients treated with western medicine.In the POF stage,the efficacy of TCM intervention is reduced to a certain extent compared with the DOR stage.The results indicated that it is feasible and operable to identify the TCM therapeutic dominant stages based on the subdivision model of disease course.

Clinical and pathological features of 52 patients with glomerulonephritis with dominant C3 / 中南大学学报(医学版)

Objective:With the in-depth study of complement dysregulation,glomerulonephritis with dominant C3 has received increasing attention,with a variety of pathologic types and large differences in symptoms and prognosis between pathologic types.This study analyzes the clinical,pathological,and prognostic characteristics of different pathological types of glomerulonephritis with dominant C3,aiming to avoid misdiagnosis and missed diagnoses. Methods:The clinical,pathological,and follow-up data of 52 patients diagnosed as glomerulonephritis with dominant C3 by renal biopsy from June 2013 to October 2022 were retrospectively analyzed.According to the clinical feature and results of pathology,15 patients with post-infectious glomerulonephritis(PIGN)and 37 patients with of non-infectious glomerulonephritis(N-PIGN)were classified.N-PIGN subgroup analysis was performed,and 16 patients were assigned into a C3-alone-deposition group and 21 in a C3-dominant-deposition group,or 27 in a C3 glomerulopathy(C3G)group and 10 in a non-C3 nephropathy(N-C3G)group. Results:The PIGN group had lower creatinine values(84.60 μmol/L vs 179.62 μmol/L,P= 0.001),lower complement C3 values(0.36 g/L vs 0.74 g/L,P<0.001)at biopsy,and less severe pathological chronic lesions compared with the N-PIGN group.In the N-PIGN subgroup analysis,the C3-dominant-deposition group had higher creatinine values(235.30 μmol/L vs 106.70 μmol/L,P=0.004)and higher 24-hour urine protein values(4 025.62 mg vs 1 981.11 mg,P=0.037)than the C3-alone-deposition group.The prognosis of kidney in the PIGN group(P=0.049),the C3-alone-deposition group(P=0.017),and the C3G group(P=0.018)was better than that in the N-PIGN group,the C3-dominant-deposition group,and the N-C3G group,respectively. Conclusion:Glomerulonephritis with dominant C3 covers a variety of pathological types,and PIGN needs to be excluded before diagnosing C3G because of considerable overlap with atypical PIGN and C3G;in addition,the deposition of C1q complement under fluorescence microscope may indicate poor renal prognosis,and relevant diagnosis,treatment,and follow-up should be strengthened.

Features of dominant eye and the significance of ocular dominance switching in the treatment of ocular diseases / 中华实验眼科杂志

The dominant eye is the eye that plays a significant role in visual perception.It plays an essential role in binocular vision and fusion functions with a complex formation mechanism.According to the principle of the dominant eye examination method, ocular dominance can be classified into sighting, motor, and sensory dominance.Changes in visual acuity or visual function due to the unbalanced progression of binocular disease may lead to the switch in the dominant eye, affecting the balance of binocular vision and the therapeutic effect.Therefore, misjudging or neglecting of the dominant eye will change the long-term visual balance between the eyes, which may affect people's visual quality and quality of life.These aspects are mainly represented in the process of refractive error correction, refractive surgery, strabismus correction surgery, amblyopia training methods and cataract intraocular lens measurement.The formulation of medical plans based on the strategy of the dominant eye can remarkably improve the reconstruction good binocular vision and the quality of life of patients.However, the role of the dominant eye in binocular vision is not fully understood, and clinicians are not sufficiently aware of its importance.Therefore, this study will review the latest research progress on the mechanism of dominant eye formation, examination methods, and clinical significance of dominant eye switching.

ObjectiveTo analyze the development status and quality of clinical practice guidelines for the treatment of dominant diseases with Chinese patent medicines （CPMs）. MethodsDatabases were searched from Jan. 2019 to Dec.2023 to collect the published clinical practice guidelines of CPMs for the treatment of dominant diseases. The information about the title， the participants， clinical problems， outcomes， evidence grade， recommendations， and recommendation strength in the included clinical practice guidelines were collected， for which the development status was analyzed， and the quality was evaluated with the Scientific， Transparent and Applicable Rankings （STAR） tool for clinical practice guidelines. ResultsTotally， 34 guidelines were included， involving 273 kinds of CPMs. One to ten （with the medium five） clinical problems were proposed from 29 clinical practice guidelines respectively. All the guidelines divided the evidence into four grades according to Grade of Recommendation Assessment， Deve-lopement an Evaluation. And 28 guidelines had five levels of recommendation strength. A total of 344 recommendations were extracted， including 86 strong-recommendations， 191 weak-recommendations （including 36 weak recommendations only based on expert consensus） and 67 recommendations with unclear recommendation strength. All guidelines had high scores in the three areas of “clinical questions （94.20%）”， “evidence （91.45%）” and “recommendations （89.06%）”， while the scores in the three areas of “registry （22.06%）”， “protocol （19.00%）” and “accessibility （31.51%）” were low. The STAR recommended stars of 8 guidelines were 5.0~4.0 stars， while that of 18 guidelines were 3.5~2.5 stars， and 8 guidelines were 2.0~1.0 stars. The three guidelines with the highest recommended stars were depressive disorder， community-acquired pneumonia， and influenza in adult. ConclusionThere is a certain gap in the quality of the published clinical practice guidelines of CPMs， and the quality of the guidelines could be further improved in registry， protocols， funds， and accessibility.

Transformation of dominant eye after small incision lenticule extraction and its effect on visual quality / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the changes of the dominant eye in myopic patients after small incision lenticule extraction(SMILE)and its effect on visual quality.METHODS: Prospective clinical study. A total of 140 patients(280 eyes)who underwent SMILE operation to correct myopia in the First Affiliated Hospital of Xinjiang Medical University from June to December 2022 were selected. They were divided into dominant eye transformation group(46 cases, 92 eyes)and non-transformation group(94 cases, 188 eyes)according to whether the dominant eye transformation occurred during the follow-up in postoperative 3 mo. The uncorrected visual acuity(UCVA)of the two groups was evaluated, the subjective visual quality was evaluated by the quality of life impact of refractive correction(QIRC)scale, and the objective visual quality was evaluated by measuring the high-order aberrations of the whole eye before and at 1 and 3 mo after surgery.RESULTS: Before SMILE, the right type of dominant eye was 105 cases, left-type was 35 cases. There were 46 cases had change at 1 mo postoperatively, and there was no new change at 3 mo after operation than 1 mo after operation. There was no significant difference in UCVA and QIRC scale score between the two groups preoperatively and at 1 and 3 mo postoperatively(P&#x003E;0.05). Comparison of the dominant eye between the two groups: the total higher-order aberrations and spherical aberrations at 3 mo postoperatively were significantly higher than those in the non-transformed group(P=0.030, 0.046); Comparison of the non-dominant eye between the two groups: trefoil in the transformed group at 1 mo postoperatively was significantly higher than that in the non-transformed group(P=0.008). The binocular difference of trefoil in the transition group was significantly higher than that in the non-transition group at 1 mo after surgery(P=0.022), with no differences in the rest parameters.CONCLUSION: Some patients may experience a change in the dominant eye after SMILE surgery, with no significant impact on subjective visual quality. The decrease of objective visual quality in the early postoperative period may be an associated factor in the dominant eye transformation.

The PICRUSt software was applied to predict the metabolic function of the flora.Results The results showed that the diversity index (Shannon index) of the flora in the youngest Nycticebus bengalensis was higher than that of the others. PCoA analysis showed that the bacterial community compositions of the four samples had a certain degree of similarity. Bacteria identified in the Nycticebus bengalensis feces included 12 phyla, 18 classes, 28 orders, 49 families, 93 genera, and 59 species. Among them, the dominant phyla were Bacteroidetes and Firmicutes with average relative abundances of 46% and 28%, respectively; The genera Bacteroides, Bifidobacterium, and Fusobacterium had higher abundances, with relative abundances of 33%, 6%, and 6%, respectively; The beneficial genus Bifidobacterium was found in all samples, with the highest relative abundance found in the younger Nycticebus bengalensis. PICRUSt function prediction analysis showed that the abundance of the functional genes related to amino acid transport and metabolism, carbohydrate transport and metabolism,was relatively high.Conclusion The use of Illumina NovaSeq high-throughput sequencing technology can comprehensively detect the fecal microbial community of the Nycticebus bengalensis. The bacterial composition of Nycticebus bengalensis has rich diversity. Many bacteria are not identified and have higher relative abundance, which need further study.

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.

Localized cystic kidney disease: a case report unveiling clinical and histopathological challenges

ABSTRACT Localized cystic kidney disease (LCKD) is a distinct renal disorder characterized by the presence of cysts within specific regions of the kidneys. We present a rare case of a 41-year-old African American man, who presented to our medical center with lower urinary tract symptoms and gross hematuria. The initial assessment culminated in the identification of an uncomplicated urinary tract infection, prompting the prescription of appropriate oral antibiotic therapy. On follow-up after 5 months, the patient presented with gross hematuria. Imaging studies revealed a mixed-density cystic lesion of 2.6 cm situated within the interpolar region of the right kidney. This cystic lesion exhibited intricate septations at the superior pole of the kidney. Robotic-assisted right partial nephrectomy was performed, and pathologic examination was diagnostic for LCKD. This report not only underscores the uniqueness of LCKD but also presents a comprehensive review of the existing literature that pertains to this condition. Particular emphasis is placed upon its inherent benign behavior and its marked divergence from the progressive trajectory commonly associated with other renal diseases. We also explored the incidental findings of the disease, its diverse clinical symptomatology, conceivable etiological underpinnings, and the array of diagnostic modalities used. Finally, similarities in histopathologic findings with polycystic kidney disease and other entities are discussed, underscoring the importance of accurate diagnosis and management.

Análisis de Variables Antropométricas y su Relación con la Fuerza Pinch / Analysis of the Anthropometric Variables and their Relationship with the Pinch Force

Resumen: La evaluación de la fuerza en la mano es utilizada en ámbitos de salud y laborales, está compuesta por la fuerza de agarre y la fuerza de pellizco o fuerza pinch (Palmar Pinch - PP y Key Pinch - KP). La fuerza pinch ha sido poco estudiada y relacionada con variables antropométricas. El objetivo del presente trabajo fue determinar la relación entre la fuerza PP y KP con el género, la dominancia, la edad y variables antropométricas. Haciendo uso de un dinamómetro Jamar y con la participación de 681 sujetos (48,9 % F y 51.1 % M) aparentemente sanos de la Ciudad de Bogotá (Colombia), quienes desempeñaban diferentes actividades ocupacionales, se encontró que las fuerzas PP y KP fueron significativamente más altas en los hombres que en las mujeres tanto en la mano no dominante (8.27 Kgf Vs 6.0 Kgf) como en la mano dominante (8.57 Kgf Vs 6.27 Kgf). Se propusieron modelos predictivos que definieron como variables principales la edad, espesor, circunferencia y circunferencia máxima de la mano. En el género femenino se estableció como variable primordial la edad, mientras que en el masculino en dos modelos se define la circunferencia de la mano y en otros dos la circunferencia máxima de la mano.

Abstract: The evaluation of the force in the hand is used in health and labor fields; it is composed of the grip force and the pinch force (Palmar Pinch - PP and Key Pinch - KP). The pinch force has not had significant amount of studies and connections with anthropometric variables. This work aimed to determine the relationship between the PP and KP strength with gender, dominance, age, and anthropometric variables. Using a Jamar dynamometer and with the participation of 681 subjects apparently healthy (48.9 % F and 51.1 % M) from the City of Bogotá (Colombia), who performed different occupational activities, it was found that the PP and KP forces were significantly higher in men than in women both in the non-dominant hand (8.27 Kgf Vs. 6.0 Kgf) and in the dominant hand (8.57 Kgf Vs 6.27 Kgf). The predictive models proposed in this study defined age, thickness, circumference, and maximum circumference of the hand as the main variables. In the female gender, age was established as the primary variable. At the same time, in the male, the circumference of the hand was defined in two models, and the maximum circumference of the hand in another two.

The study aimed to evaluate the composition and diversity of algae in the JP Lake of Jahangirnagar University campus. The research was carried out between the period of December 2021 to November 2022. A total of 72 water samples were used to carry out the investigation. Shannon and Simpson diversity indexes were used to determine the level of diversity. 234 phytoplankton species under 98 genera were found belonging to 8 classes (Cyanophyceae, Chlorophyceae, Bacillariophyceae, Synurophyceae, Euglenophyceae, Cryptophyceae, Dinophyceae, and Xanthophyceae). According to the generic percentage composition, Chlorophyceae comprised 46%, followed by Bacillariophyceae (20%) and Cyanophyceae (18%). At the species level, Euglenophyceae were found to dominate (34%) the studied sites that were followed by Chlorophyceae (31%) and Cyanophyceae (18%). The total density of phytoplankton was 387.34×105 ind/l. The highest phytoplankton density was found in April, and the lowest one was in November. 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.

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.

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.

Autosomal dominant osteopetrosis type Ⅱ: 2 cases report and literature review / 中华内分泌代谢杂志

Osteosclerosis is a rare hereditary bone metabolic disease, characterized by increased bone mass and density caused by bone resorption disorders, and any abnormal mutation involving osteoclast maturation or function will lead to the occurrence of osteopetrosis. Clinically, the prevalence of autosomal dominant osteopetrosis type Ⅱ(ADO-Ⅱ) is higher than that of other types of osteopetrosis, which involves multiple systems such as endocrine, bone, blood, nerve, ear-nose-throat, and oral cavity. Disease progression is insidious and easily overlooked, and there is no standard treatment. This article summarizes the clinical characteristics, examination data, diagnosis and treatment process of the two patients, analyzes multi-system symptoms, pathogenesis and treatment principles of the disease to improve the management of patients with ADO-Ⅱ.

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.

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.

Effects of metformin hydrochloride tablets on clinical efficacy and number of dominant follicles in polycystic ovary syndrome / 药学实践与服务

Objective To explore the effect of metformin hydrochloride tablets on the clinical efficacy, number of dominant follicles and ovarian volume of polycystic ovary syndrome. Methods 150 patients diagnosed with polycystic ovary syndrome who were diagnosed and treated in our hospital from January 2019 to March 2021 were selected .The patients were divided into observation group and control group by random number table. The control group was treated with letrozole + gonadotropin, and the observation group was treated with letrozole + gonadotropin + hydrochloric acid + Metformin tablets. The clinical efficacy, endometrial thickness, number of high-quality follicles, sex hormone levels, blood lipid levels, and adverse reactions were compared between the two groups. Results ① The effective rate of treatment in the observation group was 90.67%, which was significantly higher than that in the control group, 78.67% (P<0.05). ② After treatment, the endometrial thickness of the observation group was lower than that of the control group, and the number of high-quality follicles was more than that of the control group(P<0.05). ③ After treatment, the levels of Luteinizing Hormone-LH, Follicle Stimulating Hormone-FSH and Testosterone (T) in the observation group were lower than those in the control group (P<0.05). ④ After treatment, the total cholesterol (TC) and triglyceride (TG) in the observation group were lower than those in the control group (P<0.05). ⑤ The incidence of adverse reactions in the observation group was 8.00%, which was significantly lower than 20.00% in the control group (P<0.05). Conclusion Letrozole + gonadotropin + metformin hydrochloride tablets could significantly improve the sex hormone and blood lipid levels in patients with polycystic ovary syndrome, relieve the symptoms of the patients, and improve their uterine condition, which had a good clinical effect.
