OBJECTIVE:
To retrospectively analyze the genetic differences of thalassemia gene mutations among ethnic groups in Hechi, Guangxi.
METHODS:
A total of 15 595 whole blood samples of residents of Hechi from January 1, 2020 to June 30, 2023 were screened for thalassemia, and the Gap-PCR method and RDB-PCR method were used to perform genetic testing on the positive samples. Gene sequencing was performed on the samples with positive screening results but negative genotyping results.
RESULTS:
Among the 15 595 samples, 10 501 cases were screened positively, and 8 506 cases were thalassemia gene carriers among the positive samples, with a positive coincidence rate of 81.00%. Among them, there were 5 374 cases of α-thalassemia, 2 531 cases of β-thalassemia, and 601 cases of α+β compound thalassemia. A total of 13 mutant types were detected in α-thalassemia, including --SEA (48.57%), -α 3.7 (31.31%), α CS (8.57%) and -α 4.2 (8.07%). A total of 17 mutant types were detected in β-thalassemia, mainly CD17 (48.27%) and CD41-42 (41.24%). The thalassemia gene carriers were mainly from the Zhuang (6 106 cases), Han (969 cases), Yao (793 cases), Mulam (275 cases), and Maonan (228 cases) ethnic groups. The comparison of constituent ratios within the above five ethnic groups demonstrated that there were differences in the proportions of -- SEA, -α 3.7, α CS , and -α 4.2 among the Zhuang, Han, and Yao ethnic groups (P < 0.005). The proportion of α CS in the Mulam ethnic group was not significantly different from -α 3.7 and -α 4.2. The proportions of -- SEA, -α3.7, and α CS in the Maonan ethnic group were not significantly different. There were no significant differences in the proportion of CD17 and CD41-42 among the Han, Yao, Mulam and Maonan ethnic groups. The proportion of --SEA was the highest in the Mulam ethnic group (56.68%), which was statistically different from 35.92% in the Maonan ethnic group. The proportion of -α 3.7 was the highest in the Zhuang ethnic group (33.25%), and the difference was statistically significant compared to the Mulam ethnic group which had the lowest proportion (18.72%). The proportion of α CS was the highest in the Maonan ethnic group (27.46%), and the differences were statistically significant compared with other ethnic groups. The proportions of CD17 in the Zhuang and Maonan ethnic groups (50.79%, 55.68%) were higher than those in the Han (39.12%), Yao (39.63%) and Mulam (30.00%), and the differences were statistically significant. There was no significant difference in the proportion of CD41-42 among the above five ethnic groups.
CONCLUSIONS
The mutation type and distribution differences of genes causing thalassemia among main ethnic groups in the minority inhabited areas of Hechi, Guangxi, show the characteristics of ethnic differentiation. The result is helpful to develop a special prevention and control plan for thalassemia in line with the population distribution characteristics, and provide reference for revealing the genetic background and geographical distribution of thalassemia in this area.

ObjectiveTo investigate the distribution of traditional Chinese medicine (TCM) syndromes in intrahepatic cholestasis of pregnancy (ICP) and its association with perinatal outcomes, and to provide a basis for precise treatment based on TCM syndrome differentiation. MethodsA cross-sectional study was conducted among 275 patients with ICP who were admitted to The Affiliated Hospital of Chengdu University of Traditional Chinese Medicine from April 2023 to April 2025. A hierarchical cluster analysis was used to summarize TCM syndromes. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. A multivariate Logistic regression analysis was used to identify the clinical features significantly associated with TCM syndrome. ResultsThe cluster analysis identified three core TCM syndromes among the 275 patients with ICP, i.e., liver-gallbladder damp-heat syndrome (45.8%), syndrome of blood deficiency generating wind (30.9%), and liver depression and spleen deficiency syndrome (23.3%). There was a significant difference in the distribution of TCM syndromes between different groups stratified by maternal age at delivery, parity, history of ICP recurrence, gestational weeks at disease onset, total bile acid (TBA), alanine aminotransferase (ALT), and comorbidity with gestational diabetes mellitus (GDM) (all P<0.05). The multivariate Logistic regression analysis showed that<34 gestational weeks at disease onset was significantly associated with all three syndromes (damp-heat: odds ratio [OR]=3.769, P<0.001; blood deficiency: OR=4.031, P<0.001; liver stagnation: OR=3.552, P<0.001). Liver-gallbladder damp-heat syndrome was associated with maternal age ≥35 years at disease onset (OR=2.048, P=0.014), parity ≥2 times (OR=1.921, P=0.034), history of ICP recurrence (OR=2.404, P=0.030), ALT ≥200 U/L (OR=2.051, P=0.018), comorbidity with GDM (OR=1.944, P=0.029), and TBA ≥40 μmol/L (OR=2.542, P=0.024). The syndrome of blood deficiency generating wind syndrome was associated with maternal age ≥35 years (OR=2.939, P=0.003), parity ≥2 time (OR=3.222, P=0.003), history of ICP recurrence (OR=3.809, P=0.010), ALT ≥200 U/L (OR=2.889, P=0.006), comorbidity with GDM (OR=3.711, P=0.001), and comorbidity with hypertensive disorders of pregnancy (OR=4.472, P=0.011). Liver depression and spleen deficiency syndrome was associated with TBA ≥40 μmol/L (OR=2.995, P=0.044). The analysis of perinatal outcomes showed that there were significant differences in mode of delivery, gestational weeks at the time of delivery, postpartum blood loss, and neonatal birth weight between the three groups with different TCM syndromes (all P<0.05). ConclusionLiver-gallbladder damp-heat syndrome, syndrome of blood deficiency generating wind, and liver depression and spleen deficiency syndrome are the main TCM syndrome types in ICP, and the distribution of TCM syndromes is closely associated with clinical factors and perinatal outcomes, which provides a basis for precise TCM syndrome differentiation and individualized treatment.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34+0 weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

Objective:To observe the efficacy and adverse reactions of fractional radiofrequency (FRF) in the treatment of facial acne scars.Methods:Fifty-seven patients with facial acne depressed scars were enrolled with the nature of Dreno scars as the diagnostic criteria. They were treated with lattice radiofrequency. The treatment heads were arranged in a matrix with a treatment area of 1.2 cm ×1.2 cm, an energy density of 80-100 mJ/pin, and an interval of five-seven once a week. And they were followed up and evaluated for the clinical efficacy and adverse reactions 6 months after the last treatment. Scoring was carried out according to the ECCA weight scores, and the efficacy judged according to complete improvement, significant improvement, moderate improvement, and mild improvement.Results:After 3 times of fractional radiofrequency treatment of 57 patients, the effective rate was 44 cases, accounting for 77.2%; the ECCA weight scores before and after treatment were 65.9±25.0 and 47.7±20.2, respectively; the difference was statistically significant ( t=13.92, P<0.001); At the same time of improvement, 32 cases of patients' complexion, fineness of pores, and skin elasticity had been improved to varying degrees, and patient satisfaction was high. Adverse reactions were mainly mild burning sensation, erythema and edema, and some patients had pale yellow exudate, etc, which could be relieved in 5-7 days. Conclusions:Fractional radiofrequency treatment of facial acne scars is safe and effective, with short recovery period, few adverse reactions and high patient satisfaction.

ObjectiveTo investigate the prevalence of overweight, obesity and fatty liver disease (FLD) in adult residents in a suburban area of Shanghai, and to explore the relationship between these conditions and eating out of home (EOH). MethodsAdult residents from Zhongshan Street, Songjiang, Shanghai, were invited to report their frequency of EOH and undergo a physical examination using B-ultrasonography from May to September 2017. Binary logistic regression analyses were conducted to examine the relationship between EOH and conditions of overweight, obesity, and FLD. ResultsAmong the final sample size of 6 608 participants, the prevalence rates of overweight, obesity, and FLD were 41.65%, 14.71% and 38.29%, respectively. After adjusting for potential confounders, logistic analyses revealed that participants with an EOH frequency > once/week had a 1.44-fold higher prevalence of obesity (P=0.006), a 1.35-fold higher prevalence of overweight/obesity (P=0.005), and a 1.36-fold higher prevalence of FLD (P=0.008). ConclusionThe prevalence of overweight, obesity, and FLD is relatively high in Songjiang, Shanghai. EOH may be a risk factor for these diseases, and residents are recommended to reduce the frequency of EOH.

Objective:To study the risk factors and prognosis of pulmonary hypertension(PH) associated with bronchopulmonary dysplasia (BPD) in extremely preterm infants(EPIs).Methods:From January 2020 to December 2021, EPIs [gestational age (GA) <32 w] with BPD admitted to NICU of our hospital were retrospectively assigned into two groups: BPD with late-onset PH(PH group) and BPD without late-onset PH(non-PH group). Their general condition, treatment and prognosis were compared and the risk factors of late-onset PH were analyzed.Results:A total of 229 EPIs with BPD were enrolled, including 24(10.5%) in the PH group and 205(89.5%) in the non-PH group. The PH group had significantly smaller GA [(27.9±2.3) w vs. (28.7±1.8) w], longer mechanical ventilation [42.0(16.0, 84.0) d vs. 9.0(2.0, 23.0) d], longer hospital stay [100.5(86.3, 142.0) d vs. 77.0(56.5, 96.5)d],higher incidence of early-onset PH(54.2% vs. 9.3%) and higher mortality rate(33.3% vs. 9.8%) than the non-PH group ( P<0.05). Multivariate logistic regression analysis showed prolonged mechanical ventilation ( OR=1.046, 95% CI 1.011~1.064), early-onset PH ( OR=5.414, 95% CI 1.796~16.323) were independent risk factors for BPD with late-onset PH. 8(33.3%) patients in the PH group died, including 2 with grade Ⅱ BPD and 6 grade Ⅲ BPD. Conclusions:Prolonged mechanical ventilation and early-onset PH are independent risk factors for late-onset PH in BPD infants. BPD infants with late-onset PH have longer hospital stay, higher mortality and worse prognosis.

Objective:To compare efficacy and safety of 308-nm SQ light-emitting diode (LED) light versus 308-nm excimer light in the treatment of facial vitiligo.Methods:Patients with stable facial vitiligo were retrospectively collected from Department of Physical Therapy, Hospital of Dermatology, Chinese Academy of Medical Sciences from June 2018 to June 2020, who received treatment with 308-nm SQ LED light (LED group) or 308-nm excimer light (excimer light group). The treatment was performed once or twice a week, and patients who had received more than 8 sessions of treatment were included in the analysis of efficacy and safety. Statistical analysis was carried out by using chi-square test.Results:Totally, 68 patients with 90 lesions were enrolled into the LED group, including 36 males and 32 females, aged 25.01 ± 13.37 years; 20 patients with 28 lesions were enrolled into the excimer light group, including 13 males and 7 females, aged 27.15 ± 14.30 years. After 8 and 16 sessions of treatment, there was no significant difference in the response rate between the LED group (23.33%, 46.67%, respectively) and excimer light group (14.29%, 46.43%, χ2 = 1.05, < 0.001, respectively, both P > 0.05). During the treatment, 36 (52.94%) patients in the LED group developed persistent erythema, 17 (85%) in the excimer light group developed persistent erythema or blisters. The incidence of adverse reactions was significantly lower in the LED group than in the excimer light group ( χ2 = 16.43, P < 0.001) . Conclusion:Compared with the 308-nm excimer light, the 308-nm SQ LED light showed similar effect but higher safety for the treatment of facial vitiligo.

Objective: To investigate the incidence and trend of short-term outcomes among preterm infants born <34 weeks' gestation. Methods: A secondary analysis of data from the standardized database established by a multicenter cluster-randomized controlled study "reduction of infection in neonatal intensive care units (NICU) using the evidence-based practice for improving quality (REIN-EPIQ) study". This study was conducted in 25 tertiary NICU. A total of 27 192 infants with gestational age <34 weeks at birth and admitted to NICU within the first 7 days of life from May 2015 to April 2018 were enrolled. Infants with severe congenital malformation were excluded. Descriptive analyses were used to describe the mortality and major morbidities of preterm infants by gestational age groups and different admission year groups. Cochran-Armitage test and Jonckheere-Terpstra test were used to analyze the trend of incidences of mortality and morbidities in 3 study-years. Multiple Logistic regression model was constructed to analyze the differences of outcomes in 3 study-years adjusting for confounders. Results: A total of 27 192 preterm infants were enrolled with gestational age of (31.3±2.0) weeks at birth and weight of (1 617±415) g at birth. Overall, 9.5% (2 594/27 192) of infants were discharged against medical advice, and the overall mortality rate was 10.7% (2 907/27 192). Mortality for infants who received complete care was 4.7% (1 147/24 598), and mortality or any major morbidity was 26.2% (6 452/24 598). The incidences of moderate to severe bronchopulmonary dysplasia, sepsis, severe intraventricular hemorrhage or periventricular leukomalacia, proven necrotizing enterocolitis, and severe retinopathy of prematurity were 16.0% (4 342/27 192), 11.9% (3 225/27 192), 6.8% (1 641/24 206), 3.6% (939/25 762) and 1.5% (214/13 868), respectively. There was a decreasing of the overall mortality (P<0.001) during the 3 years. Also, the incidences for sepsis and severe retinopathy of prematurity both decreased (both P<0.001). However, there were no significant differences in the major morbidity in preterm infants who received complete care during the 3-year study period (P=0.230). After adjusting for confounders, infants admitted during the third study year showed significantly lower risk of overall mortality (adjust OR=0.62, 95%CI 0.55-0.69, P<0.001), mortality or major morbidity, moderate to severe bronchopulmonary dysplasia, sepsis and severe retinopathy of prematurity, compared to those admitted in the first study year (all P<0.05). Conclusions: From 2015 to 2018, the mortality and major morbidities among preterm infants in Chinese NICU decreased, but there is still space for further efforts. Further targeted quality improvement is needed to improve the overall outcome of preterm infants.

METHODS:
From January 2005 to December 2013, 83 patients with refractory/recurrent CD20
RESULTS:
All the patient achieved complete response. The median follow.up time was 39 months. Both the two groups collected peripheral blood stem cells successfully, and had no difference in hematopoietic reconstitution time. Three patients in treatment group and six patients in control group relapsed and the three year overall survival and EFS in treatment group was significantly higher than that in control group, that is(93.0% vs 73.1%, P=0.037) and (89.5% vs 65.4%, P=0.034), respectively. Subgroup analysis showed that: compared with the treatment group in which using R in the whole courses(before and after transplantation, and collection of stem cells) was superior to the control group in both OS and EFS, with the OS 97% vs 87.5% (P>0.05) and EFS 97% vs 76.2% (P=0.05) respectively. While stratified by the different courses of rituximab, the OS was 88.9% (1-2 courses, 9 cases), 93.1% (3-4 courses, 29 cases), 94.7%(more than 5 courses,19 cases), and EFS was 77.8%, 89.7% and 94.7%, respectively.
