Objective:
To investigate the association between expression levels of potassium voltage-gated channel subfamily Q member 1 (KCNQ1) gene and gout, so as to provide the basis for diagnosis, prevention and treatment of gout.
Methods:
A total of 179 patients diagnosed with gout at the outpatient department of Guangdong Second Provincial General Hospital were enrolled in the case group, while 179 healthy individuals matched by age (within 5 years) were selected as the control group. Demographic information, lifestyle, dietary intake and biochemical blood indicators were collected through questionnaires and laboratory tests. The relative expression levels of KCNQ1 gene mRNA were quantified using real-time fluorescence quantitative PCR. A receiver operating characteristic (ROC) curve was constructed to evaluate the diagnostic performance of KCNQ1 gene mRNA levels in distinguishing gout. The association between the relative expression level of KCNQ1 gene mRNA and gout, the interaction effects of the relative expression levels of KCNQ1 gene mRNA with dietary intake and biochemical blood indicators on gout were analyzed using a multivariate conditional logistic regression model.
Results:
There were 112 males (62.57%) and 67 females (37.43%) in the case group, with a mean age of (41.32±10.12) years. There were 98 males (54.75%) and 81 females (45.25%) in the control group, with a mean age of (40.24±7.62) years. The mRNA expression levels of the KCNQ1 gene were higher in the case group compared to the control group (P<0.05). The area under the ROC curve was 0.897 (95%CI: 0.865-0.928). Multivariate conditional logistic regression analysis revealed that KCNQ1 gene mRNA expression levels were positively associated with gout risk (OR=1.430, 95%CI: 1.171-1.747). Significant interactions were observed between KCNQ1 mRNA expression and seafood intake (OR=2.107, 95%CI: 1.175-3.779), KCNQ1 gene mRNA expression and uric acid levels (OR=2.373, 95%CI: 1.366-4.119), as well as between uric acid levels and seafood intake (OR=2.321, 95%CI: 1.159-4.678).
Conclusion
The expression levels of the KCNQ1 gene may increase the risk of gout and further increase the risk through interaction with seafood intake and uric acid levels.

ObjectiveTo elucidate the critical role of rehabilitation medical records (including electronic records) in rehabilitation medicine's clinical practice and management, comprehensively analyzed the structure, core content and data standards of rehabilitation medical records, to develop a standardized medical record data architecture and core dataset suitable for rehabilitation medicine and to explore the application of rehabilitation data in performance evaluation and payment. MethodsBased on the regulatory documents Basic Specifications for Medical Record Writing and Basic Specifications for Electronic Medical Records (Trial) issued by National Health Commission of China, and referencing the World Health Organization (WHO) Family of International Classifications (WHO-FICs) classifications, International Classification of Diseases (ICD-10/ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), this study constructed the data architecture, core content and data standards for rehabilitation medical records. Furthermore, it explored the application of rehabilitation record summary sheets (home page) data in rehabilitation medical statistics and payment methods, including Diagnosis-related Groups (DRG), Diagnosis-Intervention Packet (DIP) and Case Mix Index. ResultsThis study proposed a systematic standard framework for rehabilitation medical records, covering key components such as patient demographics, rehabilitation diagnosis, functional assessment, rehabilitation treatment prescriptions, progress evaluations and discharge summaries. The research analyzed the systematic application methods and data standards of ICD-10/ICD-11, ICF and ICHI Beta-3 in the fields of medical record terminology, coding and assessment. Constructing a standardized data structure and data standards for rehabilitation medical records can significantly improve the quality of data reporting based on the medical record summary sheet, thereby enhancing the quality control of rehabilitation services, effectively supporting the optimization of rehabilitation medical insurance payment mechanisms, and contributing to the establishment of rehabilitation medical performance evaluation and payment based on DRG and DIP. ConclusionStructured rehabilitation records and data standardization are crucial tools for quality control in rehabilitation. Systematically applying the three reference classifications of the WHO-FICs, and aligning with national medical record and electronic health record specifications, facilitate the development of a standardized rehabilitation record architecture and core dataset. Standardizing rehabilitation care pathways based on the ICF methodology, and developing ICF- and ICD-11-based rehabilitation assessment tools, auxiliary diagnostic and therapeutic systems, and supporting terminology and coding systems, can effectively enhance the quality of rehabilitation records and enable interoperability and sharing of rehabilitation data with other medical data, ultimately improving the quality and safety of rehabilitation services.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

OBJECTIVE:
To explore the genetic mechanism underlying a case with para-Bombay phenotype.
METHODS:
The ABO and Lewis phenotype were identified with serological methods. The coding regions of exons 6 and 7 of the ABO and FUT1 genes were amplified with PCR and directly sequenced. Haploid sequence analysis was carried out on the variant sites of the FUT1 gene.
RESULTS:
Serological analysis confirmed that the proband has a rare para-Bombay phenotype. Direct sequencing revealed that he was a B.01/O.01.02 heterozygote for the ABO gene, and had heterozygous deletion for the 768 and 881-882 sites of the FUT1 gene. Further haploid analysis showed that the c.881_882delTT deletion has occurred in one haploid while c.768delC was present in the other haploid. The proband was therefore determined as a FUT1*01N.13/01N.20 heterozygote, which have resulted in frameshift in polypeptide chain p.Phe294Cysfs*40 and p.Val257Phefs*23, respectively.
CONCLUSION
A rare bi-allelic heterozygous deletion of para-Bombay phenotype has been identified in a blood donor. The c.881_882delTT and c.768delC deletions may decrease the activity of α-1,2-fucosyltransferase.

Objective:To explore the effects of orienting three-dimensional porous network (type A) and honeycomb briquette-shaped vertically penetrating three-dimensional porous network (type B) on the vascularization rate of artificial dermis.Methods:The experimental research method was used. The artificial dermis was composed of a double layer of silicone layer and scaffold layer. Based on the difference of scaffold layer, they were divided into type A and type B artificial dermis (type A dermis and type B dermis, for short) containing type A and type B structure, respectively. The type A and type B structures were prepared by gradient freeze-drying technique and physical pore-making technique, respectively. The micro-morphology of two kinds of dermis scaffold was observed by scanning electron microscopy. The porosity of two kinds of dermis scaffold was measured by the Pyrex method. According to the method of national medical industry standard, the hydroxyproline content in degradation liquids and their residues in two kind of dermis were determined after degradation at 4, 8, 13, and 24 h, reflecting the degradation rates of two kinds of dermis. According to the random number table, L929 cells were divided into type A dermis group, type B dermis group, negative control group, and positive control group. The positive control group was added with minimum essential medium (MEM) containing 5% dimethyl sulfoxide, The negative control group was added with high-density polyethylene extract, and the other two groups were added with the corresponding extract. At 24 hours after culture, the growth rate of L929 cells was detected by methyl thiazolyl tetrazolium, and the cytotoxicity was graded. L929 cells and human umbilical vein endothelial cells (HUVECs) were inoculated into pore plates with two kinds of dermis preinstalled. On 1, 4, 7, and 14 d after inoculating, the adhesion and growth of L929 cells on the surfaces of the two kinds of scaffolds were detected by immunofluorescence method. On 7 d after inoculating, the migration of the above two kinds of cells into the two kinds of dermal scaffolds was detected by immunofluorescence and hematoxylin-eosin (HE) staining. Three full-thickness skin defect wounds of 5.0 cm×5.0 cm were created on both sides of the back of three 6-month-old healthy male Ba-Ma mini pigs. According to the random number table, six columns of wounds were divided into type A dermis two-step method group, type B dermis two-step method group, and type B dermis one-step method group. The wounds in type A dermis two-step method group and type B dermis two-step method group were transplanted with type A or type B dermis respectively before, and with autologous split-thickness skin grafting later. The wounds in type B dermis one-step method group were transplanted in a synchronous procedure including type B dermis (without silicone layer) and autologous skin grafting simultaneously. The bleeding, exudation, and infection of the wounds on the back in type A dermis two-step method group and type B dermis two-step method group on the 7th day after the second transplantation and in type B dermis one-step method group on the 14th day after the first transplantation were generally observed. The area of autologous skin graft was measured by the transparent film grid method, and the survival rate of autologous skin was calculated. On 4, 7, and 14 d after the first transplantation, the inflammatory cells, fibroblasts (Fbs), and capillary infiltration into the scaffolds of the three groups were detected by HE staining. On 7, 14 d after the first transplantation, the vascularization of the scaffolds was further observed by immunohistochemistry. On 28, 90 d after the first operation, the degradation of the scaffolds of type A dermis and type B dermis was observed by HE staining. Data were statistically analyzed with one-way analysis of variance, independent sample t test, and Bonferroni correction. Results:A large number of round and oval micropores were evenly distributed on the surface of type A scaffold, and the cylindrical hole walls could be observed arranging in a parallel direction in the longitudinal section. The honeycomb briquette-shaped penetrating macropores on the surface of type B scaffold were arranged in an orderly matrix. The pore walls of the honeycomb briquette-shaped penetrating macropores were connected by micropores to form a network structure. The porosity of type A dermis was (93.21±0.72)%, which was similar to (95.88±1.00)% of type B dermis ( t=4.653, P>0.05). The degradation rates of type A dermis at 4, 8, 13, and 24 h were similar to those of type B dermis at the corresponding time point ( t=0.232, 0.856, 0.258, 7.716, P>0.05). At 24 h after culture, the proliferation rates of L929 cells in the type A dermis group, type B dermis group, and negative control group were significantly higher than those of the positive control group ( t=2 393.46, 2 538.27, 1 077.77, P<0.01). The cytotoxicity rating of cells in positive control group was grade 4, while that of the other three groups was grade zero. On 1, 4, 7, and 14 d after inoculation, both L929 cells and HUVECs proliferated in a time-dependent manner in two kinds of dermal scaffolds. The adhesion growth and proliferation rate of the two kinds of cells on the surface of type B dermis was higher than that of type A dermis. On 7 d after inoculation, both L929 cells and HUVECs covered the surface of type B dermis and migrated into one side of the silicone layer. However, the above two kinds of cells migrated slowly into type A dermis, and only a few cells were found on one side of the silicone layer. There was no bleeding, exudation, or infection in the wounds repaired by type A and type B dermis. The survival rate of autologous skin grafting of 6 wounds in each group was 100%. On 4, 7, and 14 d after the first operation, inflammatory cells, Fbs, and capillaries gradually infiltrated into the scaffold layer, and the cell infiltration rate from high to low was type B dermis one-step method group, type B dermis two-step method group, and type A dermis two-step method group. The scaffold in wound in the type B dermis one-step method group gradually collapsed on 28 d after the first operation, and completely degraded in 3 months after the first operation. The scaffold degradation rate of type A dermis two-step method group was similar to that mentioned above. Conclusions:The honeycomb briquette-shaped vertically penetrating three-dimensional porous network structure of type B scaffold can accelerate its vascularization process, which is beneficial to autogenous split-thickness skin in one-step procedure to repair full-thickness skin defects wound in Ba-Ma mini pigs. Compared with the "two-step method" of staged transplantation of type A scaffold and autologous split-thickness skin, and one-step transplantation has equal efficacy and can provide a better choice for wound treatment.

Objective:To establish an individualized nomogram model to predict the risk of sarcopenia by analyzing the related factors of myopenia in elderly inpatients.Methods:Inpatients in the department of Affiliated Hospital of Qinghai University from January 2017 to December 2018, aged ≥ 60 years old, were included by the diagnostic criteria of Asian sarcopenia working group, and the independent risk factors were screened by logistic regression for the occurrence of sarcopenia. According to the independent risk factors, a nomogram model was established to predict the risk of sarcopenia. Bootstrap method was used to verify the model. C-index and calibration curve were used to evaluate the differentiation and calibration of the prediction model.Results:Totally 83 of 268 elderly patients had sarcopenia, the incidence was 30.9%. Age ( OR = 1.726, 95% CI 1.244-2.432), body mass index ( OR = 0.753, 95% CI 0.621-0.969), current smoking ( OR = 1.081, 95% CI 1.048-3.297), osteoporosis ( OR = 2.031, 95% CI 1.201-4.193) were all independent risk factors of myopenia in elderly patients. The concordance index for predicting the risk of myopenia was 0.775 (95% CI 0.722-0.827). Conclusion:Age, body mass index, osteoporosis, smoking are the independent risk factors of myopenia in elderly patients. The nomogram model can more directly evaluate the risk of sarcopenia in elderly patients.

Objective To compare the etiology of vertigo patients between flying personnel group and ordinary group and to provide evidence for the accurate diagnosis of vertigo or dizziness and the aeromedical assessment. Methods One thousand and sixteen ordinary vertigo patients,who were diagnosed by the Vertigo Center of Former Air Force General Hospital of PLA in the period from January 2017 to April 2018,were assigned to ordinary group.One hundred and fifty-three vertigo inpatients and outpatients of flying personnel,who were diagnosed by the hospital in the period from September 1984 to Augut 2018,were selected as flying personnel group.The etiological stratification analysis was conducted upon the gender and age in ordinary group.The disease spectrum was analyzed in flying personnel group.The etiological characteristics were compared between two groups. Results①In ordinary group,1 265 etiological factors were found in 1 016 vertigo patients (some of them had 2 or more etiologies).The top 7 etiological factors of the vertigo patients in ordinary group were benign paroxysmal positional vertigo (BPPV)that took 32.73 % (414/1 2 6 5 ),vestibular migraine (VM),31.46% (398/1 265 ),hypertension 12.96% (164/1 265 ),diabetes 4.03% (51/1 265 ), Meniere,s disease(MD)3.87%(49/1 265),vestibular neuritis(VN)3.87%(49/1 265),and cerebral infarction 3.24%(41/1 265).1.43%(1 7/1 265)cases were unable to categorize clearly.②The patients of ordinary group,aged from 8 to 89 yrs,were categorized to <21 yrs,21-40 yrs,41-60 yrs and >60 yrs subgroups.The top 4 etiological factors for <21 yrs group were VM (43.37%),BPPV (15.79%),VN(10.53%),and sudden deafness with vertigo(10.53%);for 21-40 yrs group were VM (46.86%),BPPV(29.7 1 %),VN (5 .86%),and hypertension (4.60%);for 41-60 yrs group were BPPV(35 .1 7%),VM(3 1 .54%),hypertension(12.30%),and MD(4.73%);and for >60 yrs group were BPPV (3 1 .28%),VM (20.5 9%),hypertension (20.05%),and cerebral infraction (6.68%). Detection rate of the top 7 etiological factors had significant difference in different age groups except VN and MD (χ2=1 3 .45-5 3 .1 6 ,P<0.0 1 ).③The etiological stratification by gender showed that the ratio of male to female was 1.00︰1.57.Detection rate of VM in female was higher than that in male. Detection rate of hypertension,MD and VN in male was higher than that in female,the difference was satistically significant (χ2=3.87-8.93,P<0.05).④In flying personnel group,184 etiological factors were found in 153 vertigo patients (some of them had 2 or more etiologies).Top 3 etiological factors were motion sickness(MS)that took 1 1 .41%(21/184),VN that took 10.32%(1 9/184)and MD that took 9.78% (18/184 ).The dizziness or vertigo with no accurate etiology took 57.61 % (106/184 ).⑤The BPPV and VM detection rate in flying personnel group were less than those in ordinary group (χ2=78.34,78.7 7 ,P<0.0 1 ).The dizziness or vertigo cases with no accurate etiology and MS,MD, VN and alternobaric vertigo cetection rate in flying personnel group were higher than those in ordinary group (χ2=6 .02-645 .5 9 ,P<0.05 ). Conclusions The causes of vertigo/dizziness are complex and diverse and patients may have more than one etiology.The etiological stratification analysis for patients is conducive to accurate diagnosis and treatment.Studying the difference of etiology between flying personnel and ordinary people will contribute to exploring the pathogenesis and prevention measures in flight environment and providing proof for aeromedical assessment.

Objective To compare the various parameters of vestibular autorotation test (VAT) between the Chinese military pilots and ordinary personnel. Methods Thirty-four pilots who had passed the physical examination,including the caloric test and video-head impulse test of vestibular functions,were selected as subj ects.They received vestibular autorotation test by VAT98-3 detector that manufactured by the WSR Company of United States.The frequencies,horizontal and vertical gains and phase shift of the vestibular ocular reflex (VOR)in VAT were analyzed and compared with the corresponding parameters of 100 ordinary personnel stored in the detector. Results By comparing the measured values of 34 military pilots with 100 ordinary personnel the significant differences were found on the horizontal gain at 2.0,2.3,4.7,5.1,5.5,5.9 Hz,the horizontal phase shift at 2.0,3.9,4.7,5.1 Hz,the vertical gain at 5.5,5.9 Hz and the vertical phase shift at 2.0,3.9, 5.1 Hz (t=2.106-18.647,P<0.05).The vertical phase shifts on the frequencies of 2.3,2.7,3.1, 3.5,4.3 Hz and the asymmetry showed insignificant difference as compared with the reference values of ordinary personnel. Conclusions The military pilots show higher gains on the 2.0 and 2 .3 Hz VAT than the ordinary personnel and the gain is close to 1 ,but on 4.7 ,5 .1 ,5 .5 ,and 5 .9 Hz.The differences should be considered in the evaluation of vestibular functions for military pilots.The aeromedical assessment should take the norm of military pilot as the reference.
