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 and clinical significance of soluble interleukin-2 receptor(sIL-2R) in patients with multiple myeloma(MM). METHODS: 54 newly diagnosed MM patients in the Second Affiliated Hospital of Fujian Medical University from February 2020 to December 2021 were selected as the observation group, and 60 healthy people in our hospital in the same period were selected as the control group. The expression levels of sIL-2R in the serum of the two groups were detected by enzyme-linked immunosorbent assay. The differences of sIL-2R expression level among different clinical parameter groups in MM patients were compared. The clinical parameters include:gender, age, ISS stage, hemoglobin, albumin, serum creatinine, lactate dehydrogenase and β₂-microglobulin, blood calcium, bone marrow plasma cell ratio and treatment response. The relationship between sIL-2R expression level and progression-free survival(PFS) and overall survival(OS) in MM patients were analyzed. RESULTS: The expression of serum SIL-2R in MM patients was significantly higher than that in healthy control group (P<0.05). The expression of sIL-2R in MM patients who did not achieve complete remission(CR) was significantly higher than those of CR patients (P=0.037). There was no significant difference in the expression of serum sIL-2R between the groups of different sex, age, ISS stage, hemoglobin concentration, albumin content, serum creatinine level, lactate dehydrogenase level, the content of β₂-microglobulin, the concentration of blood calcium, and the proportion of bone marrow plasma cells(P>0.05). The PFS of sIL-2R high expression group(15 months) was shorter than that of sIL-2R low expression group (22 months), which was significant difference (P=0.041). But there was no significant difference in OS between sIL-2R high expression group and sIL-2R low expression group (P=0.124). Univariate analysis results showed that the high expression of serum sIL-2R was associated with poor PFS in MM patients. Multivariate analysis results showed that the high expression of serum sIL-2R was still an independent adverse prognostic factor for PFS in MM patients, However, the expression of serum sIL-2R was not statistically significant in evaluating OS in MM patients by univariate and multivariate analysis. CONCLUSION The expression of serum sIL-2R in MM patients was significantly higher than that in healthy people. Serum sIL-2R is an independent prognostic factor of PFS in MM patients.

Objective: To analyze the clinical features, treatment and prognosis of solitary rectal ulcer syndrome (SRUS) in children. Methods: The clinical data of 7 children who were diagnosed with SRUS in Department of Gastroenterology in Guangzhou Women and Children' Medical Center from January 2019 to December 2021 were retrospectively analyzed. The clinical data including general demographics, clinical presentations, endoscopic and histologic features, treatment and outcome were extracted from hospital medical records. Results: The 7 patients were all males, and the age of onset was 6-12 years. The course before diagnosis was 2-36 months. The most common symptom was rectal bleeding (6 cases) and most common findings at initial colonoscopy were ulcer in 3 cases and protuberance in 4 cases, both located only in rectum. The intestinal histopathology of 5 cases showed characteristic fibromuscular obliteration of lamina propria. Five children were treated with mesalamine granules or suppositories, and 2 cases underwent local excision. The follow-up lasted for 5-24 months and found symptoms relieved in 5 cases, improved in 1 case, and no remission in 1 case. Colonoscopy after the treatment was performed in 5 children, among whom 2 cases achieved mucosal healing. Conclusions: SRUS in children is mainly presented with rectal bleeding, and has characteristic histological change of ulcer and protuberance in endoscopy. Pathology is crucial for diagnosis and differential diagnosis. Both the medical and surgical treatment are effective for SRUS.

【Objective】 To investigate the effect of transfusion-transmitted Zika virus (ZIKV) on the expression of non-coding circular RNA (hsa_circ_0001613) and the role of hsa_circ_0001613 in Zika virus replication. 【Methods】 Human adenocarcinomic alveolar basal epithelial cells (A549) were seeded on a 12-well plate at 1.8×10⁵/ well and infected with ZIKV at 0.05 MOI. The Total RNAs were isolated every day for 5 days after infection, and the relative expression level of hsa_circ_0001613 was detected by qRT-PCR. In addition, 10nM siRNA-hsa_circ_0001613 was transfected into 2×10⁵/ well A549 cells to specifically knock down the expression level of hsa_circ_0001613. 24h later, the cells were infected with ZIKV (MOI=0.05). Total RNAs were isolated at day 1-5 post-infection, proteins were extracted 96h post-infection. ZIKV replication, relative host antiviral gene expression, and interferon stimulated response element (ISRE) activity were tested using qRT-PCR, western blot and dual luciferase assay, respectively. 【Results】 The relative expression of hsa_circ_0001613 decreased significantly after 1-5 days of ZIKV infection. Knockdown of hsa_circ_0001613 inhibited ZIKV replication. Meanwhile, hsa_circ_0001613 knockdown significantly upregulated IFN-α/β and its downstream interferon-stimulated genes (ISGs) expression, also increased ISRE activity. 【Conclusion】 ZIKV infection significantly suppressed hsa_circ_0001613 expression in A4549 cells. Preliminary study indicated that hsa_circ_0001613 knockdown inhibited ZIKV replication possibly through activating type-Ⅰ IFN signaling pathway as showed by increased ISGs expression and ISRE activity.

Objective: Although single port laparoscopic surgery has achieved good clinical results, many surgeons are discouraged by the difficulties of operation, conflict of instruments, lack of antagonistic traction, and straight-line perspective. Therefore, some surgeons have proposed a single incision plus one hole laparoscopic surgery (SILS+1) surgical method. This study explored the safety and feasibility of SILS+1 for radical resection of colorectal cancer. Methods: A descriptive cohort study was carried out. The clinical data, including the operation, pathology and recovery situation, of 178 patients with colorectal cancer undergoing SILS+1 at Department of General Surgery, Nanfang Hospital, Southern Medical University from March 2018 to January 2019 were prospectively collected and retrospectively analyzed. Clavien-Dindo criteria was used for postoperative complication evaluation and visual analog scale was used for pain standard. Follow-up studies were conducted through outpatient service or telephone and the follow-up period was up to May 2019. Results: A total of 178 patients with colorectal cancer underwent SILS+1, including 111 male patients (62.4%) with an average age of 59 years. Eleven (6.2%) patients received added 1-3 operation ports during operation, and 1 patient was converted to open surgery due to ileocolic artery hemorrhage. The operative time was (135.2±42.3) minutes. The intraoperative blood loss was (34.6±35.5) ml. The number of harvested lymph nodes was 33.1±17.6. The distal margin was (4.7±17.8) cm. The proximal margin was (10.2±5.3) cm. Operation-related complications were observed in 16 patients (9.0%) within 30 days after the operation, of whom 6 had Clavien-Dindo III complications (3.4%). The postoperative pain scores were lower than 3. The average postoperative hospital stay was (5.6±2.6) days. Three patients (1.7%) returned to hospital within 30 days after operation due to intestinal obstruction and infection around stoma. The cosmetic evaluation of all the patients was basically satisfied. Conclusion: SILS+1 is safe and feasible in the treatment of colorectal cancer, and can reduce the postoperative pain.
