OBJECTIVE:
To analyze the ABO serological and molecular characteristics of a Chinese pedigree carrying an ABO*cisAB.01 allele for the blood subgroup.
METHODS:
A proband undergoing blood preparation for a surgery due to an open rupture of the extensor hallucis longus tendon in the left thumb on September 5, 2024 at Weihai Central Hospital and his family members were selected as study subjects. ABO serological type of six individuals from three generations was determined by serological methods. PCR was carried out to amplify exons 6 and 7 of the ABO gene, and the amplified products were directly sequenced. Samples of the proband and his mother, son, and daughter were subjected to clone sequencing analysis. This study was approved by the Medical Ethics Committee of Weihai Central Hospital (Ethics No.: LL-2024-269-01).
RESULTS:
Serological testing showed that the proband and his mother were of the AB subtype, whilst his daughter was A subtype B, his father was of O, his wife was AB, and his son was A. Direct sequencing showed that the proband's genotype was ABO*cisAB.01/O.01.02, and his mother, son, and daughter had all carried an ABO*cisAB.01 allele. There were significant differences in allelic competition when the A, B and O genes were co-dominant with the cisAB.01 allele, respectively.
CONCLUSION
There is allelic competition between the cisAB.01 allele and different ABO alleles. Blood type serological tests combined with molecular methods and family investigations can help ascertain and interpret the ABO blood type phenotypes.

Objective:Analysis of subtype distribution characteristics of human papillomavirus (HPV) infection, pathological findings of HPV-positive patients operated colposcopy and cervical histopathological examination in Changsha from 2020 to 2022.Methods:Retrospective analysis of HPV infection status of 60 354 patients was treated in the First Affiliated Hospital of Hunan University of Chinese Medicine from Jan. 2020 to Oct. 2022. They were divided into<25 years old group (3 250 cases), 25-34 years old group (19 406 cases), 35-44 years old group (17 297 cases), 45-54 years old group (13 104 cases), 55-64 years old group (4 793 cases) and≥65 years old group (2 504 cases). Cervical exfoliated cells were collected from women and specimen of lesion site were collected from men. HPV genotyping detection used polymerase chain reaction (PCR) and flow fluorescence hybridization, which could detect 27 HPV genotypes. Analyze the distribution of HPV subtypes in patients of different age groups and different treatment departments. Analyze the relationship between the infection of HPV subtypes and the outcome of 224 patients with HPV positive who also underwent colposcopy and cervical histopathology. Pearson correlation test was used for correlation analysis, and two-tailed P<0.05 was statistically significant; Pearson chi-square test or continuous correction chi-square test was used to compare the rates between groups, and two-tailed P<0.05 was statistically significant; Chi-square split test was used to compare multiple sample rates. The standard test was corrected according to the number of groups and then compared. The difference was statistically significant when the two-tailed P value was less than the corrected standard test. Results:The overall positive rate of HPV was 16.4% (9 909/60 354). Among all HPV positive patients, affection of single type HPV accounted for 75.5% (7 479/9 909) and affection of multi-type HPV accounted for 24.5% (2 430/9 909). The top six HPV types with infection rates from high to low were: HPV52 22.8% (2 256/9 909), HPV58 11.1% (1 097/9 909), HPV53 10.5% (1 045/9 909), HPV16 9.0% (890/9 909), HPV61 7.8% (774/9 909) and HPV6 7.6% (750/9 909). The difference of overall infection rate between different age groups was statistically significant (χ 2=536.90, P<0.001). The HPV infection rate was the highest in the<25 years old group, 30.1% (978/3 250), and it is higher than the age groups of 25-34 years old, 15.6% (3 035/19 406), group of 35-44 years old, 14.2% (2 464/17 297), group of 45-54 years old, 16.1% (2 115/13 104), group of 55-64 years old, 19.1% (915/4 793) and group of≥65 years old, 16.1% (402/2 504), with statistical significance( P<0.001 respectively). The most common types of HPV infection were type 6, 16.7% (378/2 266) and type 11, 10.5% (239/2 266) in dermatology clinics. The positive rate of HPV16 accounted for 12/17 in cervical intraepithelial neoplasia (CIN) 3 and cervical cancer cases, it was significantly higher than that in the inflammatory cases, 25.0% (35/140) and CIN1 cases, 23.0% (11/48), the statistical values were χ 2=15.02, P<0.001 and χ 2=12.48, P<0.001, respectively, all of which were statistically significant. Conclusions:HPV infection rate is highest in young people under 25 years old. Low-risk HPV6 and 11 are the main types of skin and venereal diseases. Among the total cases, high-risk HPV52, 58 and 53 are the most common types of infection with women in Changsha. However, high-grade cervical intraepithelial neoplasia and cervical cancer are more closely related to HPV16 infection.

OBJECTIVE:
To explore the characteristics of Shwachman-Diamond syndrome (SDS) in Chinese children in order to provide a reference for early diagnosis.
METHODS:
With Shwachman-Diamond syndrome, SDS, SBDS gene and inherited bone marrow failure as the keywords, the search period was set from January 2002 to October 2022. Relevant literature was retrieved from the Wanfang Database and China National Knowledge Infrastructure (CNKI) database. In addition, by using Shwachman-diamond syndrome as a keyword, the search period was also retrieved from the Web of Science, PubMed, and MEDLINE databases from January 2002 to October 2022. A child with SDS treated at the Tongji Hospital was also included. A total of 44 cases with complete clinical data were analyzed with reference to the International Standard for SDS Diagnosis. Chi-square test and t test were used for statistical analysis. Evidence-based research was carried out in the form of systematic review. The epidemiology, clinical characteristics and key points of early diagnosis of the Chinese SDS children were summarized and compared with the international data.
RESULTS:
The main characteristics of SDS in Chinese children were summarized as follows: The ratio of males to females was about 1.3 : 1, the median age of onset was 3 months, and the median age of diagnosis was 14 months. The first symptoms were often exocrine pancreatic insufficiency (31.8%) and granulocytopenia with infection (31.8%). According to the international consensus, the incidence rates of the three major diseases of SDS were hemocytopenia (95.4%), pancreatic disease (72.7%), and bone abnormality (40.9%). The common factors underlying SDS disease were variants of the SBDS gene (c.258+2T>C and c.183_184TA>CT), albeit there was no significant correlation between genotype and phenotype (P > 0.05). Compared with international reports, the clinical manifestations and genotypes of Chinese SDS children are different (P < 0.05).
CONCLUSION
The SDS children have an early age of onset and significant individual difference. It is necessary to analyze the case-related data to facilitate early recognition, diagnosis and clinical intervention.

Objective:To explore the main factors of hypothyroidism after radiotherapy and to identify the optimal thyroid dosimetric parameters by analyzing the dosimetric parameters of the thyroid.Methods:The general clinical characteristics and dosimetric parameters of 206 patients with nasopharyngeal carcinoma treated in Cancer Hospital of University of Chinese Academy of Sciences were collected, and the correlation between them and the incidence of hypothyroidism was analyzed.Results:The incidence of hypothyroidism in patients with nasopharyngeal carcinoma after radiotherapy was 50.49%(104/206). Univariate analysis showed that gender, N-stage, volume, mean dose, V 20Gy, V 25Gy, V 30Gy, V 35Gy, V 40Gy, V 45Gy of thyroid were associated with the incidence of hypothyroidism. Multivariate analysis demonstrated that volume (≤12.82 cm 3) and mean dose of thyroid were the independent risk factors of hypothyroidism. Mean dose of thyroid combined with volume could significantly predict the incidence of hypothyroidism after radiotherapy. Conclusion:Mean dose of thyroid ≤ 47.21 Gy is the optimal dosimetric parameter for radiation-induced hypothyroidism, especially the patients with thyroid volume ≤ 12.82 cm 3 should pay more attention to the protection of thyroid gland during radiotherapy.

Objective:To preliminarily evaluate the efficacy and safety of stereotactic body radiotherapy (SBRT) for pulmonary oligometastatic tumors from head and neck carcinoma.Methods:Clinical data of 24 patients with pulmonary oligometastasis from head and neck carcinoma undergoing SBRT in Zhejiang Cancer Hospital from January 2014 to May 2019 were retrospectively analyzed. Survival analysis was performed by Kaplan- Meier method. Results:Among the 24 patients, 12 cases were diagnosed with nasopharyngeal origin and 12 cases of non-nasopharyngeal origin. A total of 34 pulmonary metastatic lesions were treated with SBRT. The median follow-up time was 19.5 months. Thirteen cases developed new lesions after SBRT, and 9 of them occurred within 1 year after SBRT treatment. The actual 1-year local control rate was 95%. The median progression-free survival was 15.2 months, and the 1-and 2-year progression-free survival were 59% and 46%, respectively. The 2-and 3-years overall survival rate at were 71% and 51% fter lung metastasis, respectively. Univariate analysis showed that the patients with primary lesions located in nasopharynx and disease-free interval of more than 1 year had survival advantage. No more than grade 3 radiation-induced injury was observed in the whole cohort after SBRT, and the incidence of mild radiation-induced injury was 13%.Conclusions:SBRT is safe and effective in the treatment of pulmonary oligometastatsis from head and neck carcinoma, and it may be more effective for patients with primary tumors located in nasopharynx.

Objective:To analyze the clinical value of serum 2019 novel coronavirus (2019-nCoV) immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies in the diagnosis of COVID-19.Methods:A total of 116 patients diagnosed with NCP in the First Affiliated Hospital of Hunan University of Chinese Medicine and the First Affiliated Hospital of Xiamen University were enrolled from January to February 2020 as the disease group. A total of 134 cases, including 84 non-NCP inpatients and 50 healthy individuals served as the control group. Serum samples from all subjects were collected. A fully-automated chemiluminescence immunoassay analyzer was used to detect the concentration of 2019-nCoV IgM and IgG antibodies in serum. The sensitivity and specificity of the 2019-nCoV IgM and IgG antibody single test and combined detection were compared using the χ 2 test. χ 2 test and Wilcoxon′s rank sum test were used to compare the positive rates and concentrations of IgM and IgG antibodies in NCP patients before and after their 2019-nCoV nucleic acid tests turning negative, respectively. The change trend of 2019-nCoV antibody concentration in the process of NCP patients was analyzed by Wilcoxon′s rank sum test. Results:The sensitivity of 2019-nCoV IgG (90.5%, 105/116) was higher than that of 2019-nCoV IgM (75.9%, 88/116), the difference was statistically significant (χ 2=8.91, P<0.05); The specificity of 2019-nCoV IgG (99.3%,133/134) was higher than that of 2019-nCoV IgM (94.0%, 126/134), the difference was statistically significant (χ 2=5.63, P<0.05). The sensitivity (89.7%,87/97) of 2019-nCoV IgM combined with IgG was higher than that of 2019-nCoV IgM, the difference was statistically significant (χ 2=6.89, P<0.05). The specificity (100%, 125/125) of 2019-nCoV IgM combined with IgG was higher than that of 2019-nCoV IgM, the difference was statistically significant (χ 2=7.70, P<0.05). After 2019-nCoV nucleic acid test converted to negative, the positive rate (9/17) and concentration [13.0 (4.9, 24.7) AU/ml] of serum 2019-nCoV IgM antibody were significantly lower than those when the nucleic acid test was positive, positive rate (15/17) and concentration [29.5 (14.0, 61.3) AU/ml], respectively (χ 2=5.10, Z=-3.195, both P<0.05). In the course of NCP, patients′ serum samples were collected from the first day of diagnosis to every three days, three times in total. The first 2019-nCoV IgM and IgG antibody concentrations [19.4 (12.4, 63.7) AU/ml, 105.8 (74.8, 126.1) AU/ml, respectively] were significantly higher than the second concentrations [15.8 (7.1, 40.3)AU/ml, 80.5 (66.7, 105.9) AU/ml], Z were-2.897,-3.179, both P<0.05. Conclusions:2019-nCoV IgG antibody has a good application value in the diagnosis of NCP. The concentration of 2019-nCoV IgM antibody has a certain correlation with the detection of 2019-nCoV nucleic acid. The combination of 2019-nCoV IgM and IgG antibodies with 2019-nCoV nucleic acid test may be the best laboratory index for the diagnosis of NCP at present.

Objective:To analyze the relationship between hematological examination combined with clinical factors and radiation-induced hypothyroidism (HT) in patients with nasopharyngeal carcinoma (NPC).Methods:Clinical data of 206 patients with NPC who received radiotherapy in Cancer Hospital of University of Chinese Academy of Sciences between January 2015 to August 2018 were retrospectively analyzed. The correlation between general clinical data, hematological examination and HT was analyzed to establish a hematological prediction model.Results:Univariate analysis showed that sex, N-stage, thyroid volume, average dose, V 20Gy, V 25Gy, V 30Gy, V 35Gy, V 40Gy, V 45Gy, fibrinogen content, cholinesterase and neutrophil count were closely associated with the incidence of HT. Multivariate analysis showed that thyroid volume, fibrinogen content and cholinesterase were the independent predictors of HT. Conclusion:The combination of sex, N-stage, thyroid volume, dose parameters, fibrinogen content, cholinesterase, neutrophil percentage and neutrophil count can predict the incidence of HT (AUC=0.777).
