目的 分析人类疱疹病毒(EBV)致传染性单核细胞增多症(IM)患儿病毒量与临床特征的关系。方法 选取我院2016年1月—2021年1月收治的EBV定量阳性的IM患儿128例,按照患儿EBV含量分为低病毒量组(n=64)和高病毒量组(n=64)。比较不同病毒含量组患儿的症状体征、实验室检查及临床特征,并分析具有统计学差异的指标与病毒量之间的相关性。结果 高EBV含量组患儿丙氨酸氨基转移酶、乳酸脱氢酶、血沉、外周血白细胞计数指标水平均高于低EBV含量组(P<0.05)。患儿的退热时间、淋巴结缩小时间、肝脾肿大消退时间及住院时间均随着EBV含量的增加而延长(P<0.05)。EBV含量与退热时间、淋巴结缩小时间、肝脾肿大消退时间及住院时间成正相关(r=0.453,0.458,0.402,0.415,P<0.05)。结论 EBV含量越高,IM患儿住院时间及临床指标恢复时间越长,因此临床治疗IM患儿时可以根据EBV含量的高低进行病情评估。

Objective To analyze the relationship between viral load and clinical characteristics in children with infectious mononucleosis (IM) caused by Epstein-Barr virus (EBV). Methods A total of 128 children with IM who tested positive for EBV and admitted to our hospital from January 2016 to January 2021 were selected and divided into low virus group (n=64) and high virus group (n=64) according to their EBV level. The symptoms and signs, laboratory examinations and clinical characteristics of two groups were compared, and the correlation between the statistically different indicators and the amount of virus were analyzed. Results In children with high EBV level, the levels of alanine aminotransferase, lactate dehydrogenase, erythrocyte sedimentation rate, and peripheral blood white blood cell count were higher than low EBV level group (P<0.05). The time of fever, lymph node shrinkage, hepatosplenomegaly to subside, and hospitalization time of the children were all prolonged with the increase of EBV level (P<0.05). The level of EBV was positively correlated with the time to allay fever, the time to shrink the lymph nodes, the time to improve hepatosplenomegaly, and the length of hospital stay (r=0.453, 0.458, 0.402, 0.415,P<0.05). Conclusions The higher EBV level, the longer hospitalization time and recovery time of clinical indicators in children with IM. Therefore, the disease assessment of children with IM can be based on EBV level.

Objective To explore the diagnostic value of liquid-based cytology combined with squamous cell carcinoma antigen (SCCA) and cancer antigen 153 (CA153) detection in patients with cervical cancer. Methods Liquid-based cytology, serum SCCA, and serum CA153 were detected on 54 patients with cervical intraepithelial neoplasia (neoplasia group), 54 patients with cervical cancer (cancer group), and 54 healthy subjects (control group). Pathological biopsy diagnosis was used as the gold standard. The diagnostic value of liquid-based cytology, serum SCCA, and serum CA153 in cervical cancer was analyzed, and the clinical value of combining liquid-based cytology with serum SCCA and serum CA153 detection was also analyzed. Results The levels of serum SCCA and CA153 in neoplasia group and cancer group were higher than those in control group, and the serum SCCA and CA153 levels in the cancer group were higher than those in the neoplasia group (P<0.05). In the single detection, the positive rate of liquid-based cytology was higher than that of serum SCCA and CA153, and the positive rate of combined detection was significantly higher than those of the single detection (P<0.05). Conclusions Cervical cancer patients have high levels of serum SCCA and CA153. Liquid-based cytology combined with SCCA and CA153 detection has high positive rate for early cervical cancer.

Objective To investigate the effects of different concentrations of sinomenine on proliferation, cell cycle and apoptosis of renal carcinoma cells. Methods The renal carcinoma cells were treated with different concentrations of sinomenine. MTS was used to analyze the effects of sinomenine on proliferation in 786-O renal carcinoma cells, the cell cycle changes were determined using flow cytometry, while the changes of apoptosis were detected by Annexin V-FITC / PI double staining. The expression of apoptosis-related proteins such as c-myc, Bax and Caspase-3 were detected by Western blot. Results Sinomenine significantly inhibited the proliferation of 786-O cells and induced cell cycle arrest and apoptosis in G1/S phase. With the increase of sinomenine concentration, the inhibition rate increased gradually. Sinomenine significantly down-regulated the expression of c-myc protein, while the expressions of the apoptotic protein Bax, Caspase-3 were up-regulated. Conclusions Sinomenine can significantly inhibit the expression of c-myc in 786-O cells, reduce proliferation ability, and induce cell cycle arrest and apoptosis. Sinomenine may have a potential therapeutic effect on renal cancer.

大便失禁是肛肠外科常见疾病,可导致患者生活质量下降,并引起一系列社会心理问题,其发病率随着年龄增加明显上升。肛门括约肌复合体损伤是大便失禁的最常见原因。目前的治疗方式包括保守治疗和手术治疗,但治疗效果仍不理想,尤其是长期治疗效果较差。最近,许多临床前和临床研究对大便失禁的干细胞疗法进行了探索,作为一种新的治疗方式,干细胞疗法有望彻底治愈大便失禁。本文就干细胞疗法治疗大便失禁的动物模型、损伤和修复机制、疗效等方面进行综述。

Fecal incontinence is a common anorectal surgical condition that can lead to decreased quality of life and a range of psychosocial problems in patients, and its incidence increases significantly with age. Damage to the anal sphincter complex is the most common cause of fecal incontinence. Current treatment modalities include conservative and surgical treatment, but treatment outcomes remain suboptimal, especially in the long term. Recently, many preclinical and clinical studies have explored stem cell therapy for fecal incontinence as a new treatment modality that holds promise for a complete cure of fecal incontinence. This paper presents a review of animal models, mechanisms of injury and repair, and efficacy of stem cell therapy for fecal incontinence.

Objective To understand the characteristics of Rh-negative red blood cells (RBC) supply, improve the management of storage and guarantee the safety of blood transfusion. The collection and supply of Rh-negative RBC in Guangzhou city was retrospectively analyzed. Methods The amount of Rh-negative RBC collection and supply, the distribution of ABO blood type and the consumption of blood by different hospitals in Guangzhou Blood Center from 2011 to 2017 were statistically analyzed. Results During 2011-2017, 11 283 U Rh-negative RBC was collected in Guangzhou Blood Center, accounting for 0.39% of total RBC collection (11 283/2 902 485); 1 693 U Rh-negative RBC was supplied, accounting for 0.43% of the total blood supply (11 693/2 762 229). The proportion of suspended RBC supply increased year by year, in contrast with the decease of proportion of frozen defrosteddeglyceal RBC supply. In addition, the growth rate of Rh-negative suspended RBC supply was higher than that of RBC collection since 2014 (F=217, P<0.05). A-and B-Rh negative suspended RBC supply increased, with growth rates of 137.3% and 134.1%, respectively. The Rh negative RBC was predominantly supplied to Grade III and general hospitals. Conclusion By establishing a team of Rh-negative regular blood donors, the strategies for recruitment, collection and supply of Rh-negative RBC should be continuously improved according to the characteristics of Rh-negative RBC collection and supply in Guangzhou. The coordinating management of Rh-negative, as well as the communication of clinical departments, departments of transfusion and blood banks should be improved. In addition, the balance between supply and demand of Rh-negative blood should be promoted, and the safety of blood transfusion for Rh-negative patients can be improved.
