Objective To analyze the risk factors and survival status of Epstein-Barr virus(EBV)infection in pa-tients with aplastic anemia(AA)after haploid allogeneic hematopoietic stem cell transplantation(Haplo-HSCT).Methods Clinical data of 78 AA patients who underwent Haplo-HSCT in the hematology department of a hospital from January 1,2019 to October 31,2022 were analyzed retrospectively.The occurrence and onset time of EBV viremia,EBV-related diseases(EBV diseases),and post-transplant lymphoproliferative disorders(PTLD)were ob-served,risk factors and survival status were analyzed.Results Among the 78 patients,38 were males and 40 were females,with a median age of 33(9-56)years old;53 patients experienced EBV reactivation,with a total inci-dence of 67.9%,and the median time for EBV reactivation was 33(13,416)days after transplantation.Among pa-tients with EBV reactivation,49 cases(62.8%)were simple EBV viremia,2 cases(2.6%)were possible EBV di-seases,and 2 cases(2.6%)were already confirmed EBV diseases(PTLD).Univariate analysis showed that age 1<40 years old at the time of transplantation,umbilical cord blood infusion,occurrence of acute graft-versus-host disease(aGVHD)after transplantation,and concurrent cytomegalovirus(CMV)infection were independent risk fac-tors for EBV reactivation in AA patients after Haplo-HSCT.Multivariate analysis showed that concurrent CMV in-fection was an independent risk factor for EBV reactivation in A A patients after Haplo-HSCT(P=0.048).Ritu-ximab intervention before stem cell reinfusion was a factor affecting the duration of EBV reactivation(P<0.05).The mortality of EBV viremia,EBV diseases,and PTLD alone were 8.2%,50.0%,and 100%,respectively.The 2-year overall survival rate of patients with and without EBV reactivation were 85.3%,and 90.7%,respectively,difference was not statistically significant(P=0.897).However,patients treated with rituximab had 2-year lower survival rate than those who did not use it,with a statistically significant difference(P=0.046).Conclusion EBV reactivation is one of the serious complications in AA patients after Haplo-HSCT,which affects the prognosis and survival of patients.

OBJECTIVE:
This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province.
METHODS:
We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed.
RESULTS:
The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α 3.7/αα (50.23%) and β IVS-II-654/β N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively.
CONCLUSION
Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.

OBJECTIVE:
To investigate the expression of MC1R in esophageal squamous cell carcinoma and its correlation with the clinicopathological parameters.
METHODS:
We analyzed the expression of MC1R in esophageal cancer based on data from TCGA databse and examined its expression levels using RT-PCR and Western blotting in a human esophageal epithelial cell line BAr-T, human esophageal squamous cell carcinoma cell lines ECA109, KYSE30, KYSE150, KYSE510, TE-1, TE-13, and EC9706, a human gastric cancer cell line SGC7901 and 19 pairs of esophageal squamous cell carcinoma tissues and adjacent tissues.Immunohistochemistry was used to detect MC1R expression levels in 32 pairs of paraffin-embedded sections of esophageal squamous cell carcinoma and adjacent tissues, and the correlation of MC1R expression and the patients'clinicopathological characteristics was analyzed.
RESULTS:
Bioinformatics analysis showed that MC1R was significantly overexpressed in esophageal cancer tissues (P < 0.05).MC1R expression was also increased in 5 esophageal squamous cell carcinoma cell lines ECA109, KYSE30, KYSE510, TE-13, EC9706 and the gastric cancer cell line SGC7901 as compared with that in esophageal epithelial cells (P < 0.05).Immunohistochemistry revealed significantly increased MC1R expression in esophageal squamous cell carcinoma tissue sections in comparison with the adjacent tissue sections (P < 0.05).In patients with esophageal squamous cell carcinoma, a high MC1R expression was detected mainly in those with an old age, positive for middle-thoracic involvement, and with moderately differentiated tumor cells, and showed a correlation with T stage of tumor (P < 0.05), but not with the other clinicopathological parameters such as gender, age, degree of cell differentiation, primary tumor site, or TNM stage (P>0.05).
CONCLUSION
MC1R is highly expressed in esophageal squamous cell carcinoma and may serve as a molecular biomarker to assist in the diagnosis of esophageal squamous cell carcinoma.

BACKGROUND:
Psoriasis is a chronic inflammatory skin disease, affecting about 0.6% of the Chinese population. Many patients are not well controlled by conventional treatments, thus there is need for new treatment regimens. In this study, we assessed the efficacy and safety of secukinumab in Chinese patients with moderate to severe plaque psoriasis.
METHODS:
This study was a 52-week, multicentre, randomized, double-blind, placebo-controlled, parallel-group, Phase 3 trial. A sub-population of study participants (≥18 years) of Chinese ethnicity were randomized to receive subcutaneous injections of 300 or 150 mg secukinumab, or placebo. The co-primary endpoints were psoriasis area severity index (PASI) 75 and Investigator's Global Assessment (IGA) 0/1 at Week 12.
RESULTS:
A total of 441 Chinese patients were enrolled in this study. Co-primary outcomes were achieved; 300 and 150 mg secukinumab were superior to placebo as shown in the proportion of patients that achieved PASI 75 (97.7% and 87.2% vs. 3.7%, respectively; P < 0.001), and IGA 0/1 (82.3% and 69.7% vs. 2.7%; P < 0.001) at Week 12. Treatment efficacy was maintained until Week 52. There was no increase in overall adverse events with secukinumab relative to placebo throughout the 52-week period.
CONCLUSION:
Secukinumab is highly effective and well tolerated in Chinese patients with moderate to severe plaque psoriasis.

BACKGROUND:
Imprecise interpretation of coronary angiograms was reported and resulted in inappropriate revascularization. Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score is a comprehensive system to evaluate the complexity of the overall lesions. We hypothesized that a real-time SYNTAX score feedback from image analysts may rectify the mis-estimation and improve revascularization appropriateness in patients with stable coronary artery disease (CAD).
METHODS:
In this single-center, historical control study, patients with stable CAD with coronary lesion stenosis ≥50% were consecutively recruited. During the control period, SYNTAX scores were calculated by treating cardiologists. During the intervention period, SYNTAX scores were calculated by image analysts immediately after coronary angiography and were provided to cardiologists in real-time to aid decision-making. The primary outcome was revascularization deemed inappropriate by Chinese appropriate use criteria for coronary revascularization.
RESULTS:
A total of 3245 patients were enrolled and assigned to the control group (08/2016-03/2017, n = 1525) or the intervention group (03/2017-09/2017, n = 1720). For SYNTAX score tertiles, 17.9% patients were overestimated and 4.3% were underestimated by cardiologists in the control group. After adjustment, inappropriate revascularization significantly decreased in the intervention group compared with the control group (adjusted odds ratio [OR]: 0.83; 95% confidence interval [CI]: 0.73-0.95; P = 0.007). Both inappropriate percutaneous coronary intervention (adjusted OR: 0.82; 95% CI: 0.74-0.92; P < 0.001) and percutaneous coronary intervention utilization (adjusted OR: 0.88; 95% CI: 0.79-0.98; P = 0.016) decreased significantly in the intervention group. There was no significant difference in 1-year adverse cardiac events between the control group and the intervention group.
CONCLUSIONS:
Real-time SYNTAX score feedback significantly reduced inappropriate coronary revascularization in stable patients with CAD.

OBJECTIVE:
To assess the efficacy and safety of the Chinese medicine Dingkun Pill (, DKP) on insulin resistance in women with polycystic ovary syndrome (PCOS).
METHODS:
A total of 117 women with PCOS were randomly assigned to Group A (38 women), Group B (40 women), or Group C (39 women) in a randomization sequence with SAS software and a 1:1:1 allocation ratio using random block sizes of 6, and were given 7 g of oral DKP daily (Group A), 1 tablet of Diane-35 orally daily (Group B), or 7 g of oral DKP daily plus 1 tablet of Diane-35 orally daily (Group C). Patients took all drugs cyclically for 21 consecutive days, followed by 7 drug-free days. The treatment course for the 3 groups was continued for 3 consecutive months. Oral glucose tolerance tests (OGTT) were performed before treatment and again after 2 and 3 months of therapy, respectively, and homeostasis model assessment for insulin resistance (HOMA-IR) and quantitative insulin sensitivity check index (QUICKI) were calculated.
RESULTS:
Of 117 women with PCOS, 110 completed the entire course of therapy: 35 in Group A, 36 in Group B, and 39 in Group C. After treatment, all three groups showed significant decreases in fasting glucose: at 1 h glucose decreased significantly in Group A (by 0.5 ± 1.4 mmol/L, P=0.028) and Group C (by 0.5 ± 1.2 mmol/L, P=0.045); while showing a tendency to increase in Group B (by 0.4 ± 1.9 mmol/L, P=0.238). HOMA-IR decreased significantly in Group C [by 0.5 (-2.2 to 0.5) mIU mmol/L, P=0.034]. QUICKI was significantly increased in Groups A and C (by 0.009 ± 0.02, P=0.033 and by 0.009 ± 0.027, P=0.049, respectively), while no change was observed in Group B. Repeated-measure ANOVA showed that the absolute changes in all parameters (except for glucose at 1 h), including glucose and insulin levels at all time-points during OGTT and in HbA1c, HOMA-IR, and QUICKI, were not significantly different among the 3 groups after treatment (P>0.05).
CONCLUSION
DKP or DKP combined with Diane-35 produce a slight improvement in insulin sensitivity compared with Diane-35 alone in PCOS patients (Trial Registration: ClinicalTrials.gov, NCT03264638).
