ABSTRACT

OBJECTIVES@#To assess the growth of preterm infants up to a corrected age of 24 months, and to understand the growth trend and pattern of preterm infants.@*METHODS@#A preterm infant follow-up database was established based on the Internet Plus follow-up system. A total of 3 188 preterm infants who were born from April 2018 to April 2021 were enrolled. Their length, weight, and head circumference were recorded at birth and at the corrected ages of 1, 3, 6, 12, 18, and 24 months. The preterm infants were grouped by perinatal factors. The growth curves of these infants were plotted and compared with the International Fetal and Newborn Growth Consortium for the 21st Century (INTERGROWTH-21st) standard and World Health Organization (WHO) standard.@*RESULTS@#The weight, length, and head circumference curves of each group of preterm infants grouped by various perinatal factors all rose rapidly within the corrected age of 6 months, but the growth rate slowed down after the corrected age of 6 months. Based on the actual age for the groups of preterm infants with different gestational ages (<28 weeks, 28-31@*CONCLUSIONS@#The physical growth rate of preterm infants is faster within the corrected age of 6 months, and the growth rate slows down after the corrected age of 6 months. Preterm infants with a smaller gestational age need longer time to catch up in weight and head circumference. More attention should be paid to the physical growth of extremely preterm infants, extremely low birth weight infants, and small-for-gestational-age infants.

ABSTRACT

OBJECTIVE@#To investigate the clinical characteristics of the patients with chronic myeloid leukemia (CML) discontinued tyrosine kinase inhibitors (TKI) therapy and the outcome of the patients.@*METHODS@#35 cases of CML patients experienced initiative discontinuation of TKI therapy in our hospital from June 1st 2015 to December 31th 2019 were retrospectively analyzed. The TFR of the patients and the factors affecting it were analyzed.@*RESULTS@#The median duration of TKI administration was 72 (range 35-173) months in the 35 patients. Among these patients, 8 had experienced TKI dose reduction or suspension. All the enrolled patients have achieved at least MMR. The median time for these patients achieving MMR was 15 (range 3-75) months after administration of TKI, and for MMR maintenance before TKI suspension was 55 (range 13-164) months. After TKI withdrawal the median follow up time was 20.3 (range 3-57.9) months, 22 out of 35 patients kept TFR, among them, 2 (5.71%) patients restarted TKI after 12 month suspension, and maintained MMR during suspension. 13 (37.1%)patients lost MMR, among them, 9 patients restarted TKI treatment, and 5 of them achieved MR4.0 after the median duration of 3(2-5) month. No patients were found to have disease progression. The estimated TFR rate was 57.8% and 51.8% at 12 and 24 months after discontinuation, respectively. Other clinical characteristic related to relapse were also analyzed, including the cumulative TKI administration duration, cumulative MMR duration, time to achieve MMR, median age at diagnosis, risk stratification by Sokal score, TKI dose reduction and discontinuation history, and second-generation TKI administration before stopping TKI, however, no statistical difference was found.@*CONCLUSION@#TKI discontinuation is practical for CML patients in our center.

ABSTRACT

Processing of Chinese medicinals with vinegar is one of the characteristic processing techniques. Vinegar is vital for the quality of vinegar-processed decoction pieces. However, there have been no specified standards for adjuvants. Through consulting relevant literature and monographs, we comprehensively reviewed the historical evolution of processing with vinegar in records, selection and application of vinegar, and summarized the relevant standards and current status of vinegar as an adjuvant in China. According to the records in literature, vinegar is effective in activating blood, moving qi, dispersing blood stasis, removing toxin, promoting appetite, and nourishing the liver. Traditionally, rice vinegar is chosen in processing. Nowadays, the vinegar made from rice under solid-state fermentation should be chosen. At present, only food standards can be taken for reference for vinegar in the processing. Integrative and specific inspection indicators are lacking, so the standards for adjuvants need to be improved urgently. In addition, the inadequacy in quality control and management is also a major problem to be solved. Through literature research, we reviewed the historical evolution and research advance in vinegar to provide a reference for the standardization and further research of vinegar used in the Chinese medicinal processing.

ABSTRACT

OBJECTIVE@#To evaluate the efficacy and safety of different types of red blood cell (RBC) transfusion and hormone therapy in patients with autoimmune hemolytic anemia (AIHA).@*METHODS@#The clinical data and serological characteristics of 40 patients with AIHA treated in our hospital from 2014 to 2018 were collected and analyzed retrospectively. The efficacy and safety of different type of RBC transfusion and hormone therapy were evaluated according to the principle of minimally incompatible RBC transfusion after cross-matching.@*RESULTS@#Among 40 patients with AIHA, the female cases were more than the male cases, the cases of secondary AIHA was more than cases of primary AIHA, and the warm autoantibodies were in the majority. 11 cases of AIHA underwent 26 times minimally incompatible red blood cell transfusions. The total effective rate was 46.2%, the partial efficiency was 23.1%, and total inefficiency was 30.8%. Among them, the same type of non-washing red blood cell group showed efficiency of 42.1%, partial effective rate of 21.1%, and inefficiency of 36.8%; the same type of washed red blood cell group showed efficiency of 57.1%, partial effective rate of 28.6%, and inefficiency of 14.3%. the infusion effects was not significanly different between the two groups, and no hemolytic transfusion reaction occurred. In the hormone-treated group, the complete remission rate was 15.2%, the partial remission rate was 63.6%, and the ineffective rate was 21.2%. Among them, the side effects appeared in 2 patients after using hormones.@*CONCLUSION@#When AIHA patients need blood transfusion, use the same type of non-washed red blood cells or homologous washed cells is relatively safe, and the difference in efficacy is not significant. The partial remission of patients received hormone therapy is much higher than that of red blood cell transfusion, but the side effects easily happen.

ABSTRACT

OBJECTIVE@#To compare the assessment results of the Children Neuropsychological and Behavioral Scale-Revision 2016 (CNBS-R2016) between young children with autism spectrum disorder (ASD) and global developmental delay (GDD, without ASD) and to explore whether CNBS-R2016 could be helpful to early identification of ASD.@*METHODS@#A total of 260 ASD and 371 GDD children aged 18-30 months were enrolled to finish the assessment of CNBS-R2016. The development quotients (DQs) of the five domains of CNBS-R2016 including gross motor, fine motor, adaptability, language and social behavior were compared between the two groups. The receiver operating characteristic (ROC) curve was used to evaluate the value of the autism-predicted domain in identifying ASD and GDD.@*RESULTS@#The DQs of all the five domains in the ASD group were lower than those in the GDD group (P<0.05). The language DQ and total DQ of the ASD group had a negative correlation with the score of the autism-predicted domain (r=-0.566, -0.552 respectively, P<0.01). When the cut-off value of the autism-predicted domain was 10.5, the largest area under the ROC curve was 0.835, and the sensitivity and specificity for the diagnosis of ASD were 0.750 and 0.798 respectively.@*CONCLUSIONS@#The development of ASD children aged 18-30 months is worse than that of GDD children. CNBS-R2016 may be helpful to distinguish ASD from children with developmental delay.

ABSTRACT

OBJECTIVE@#To propose and evaluate the clinical effect of midpiece facial nerve dissection through transparotid approach in regional parotidectomy.@*METHODS@#A total of 136 patients with benign parotid tumors were categorized into three groups according to the way of facial nerve dissection: anterograde dissection from main trunk (anterograde, n=70), retrograde dissection from distal branches (retrograde, n=34), and midpiece dissection through transparotid approach (middle dissection, n=32). Surgery duration, facial nerve injury, salivary fistula, earlobe sensation, Frey's syndrome, and aesthetic evaluation were compared.@*RESULTS@#The surgery duration in the middle dissection group was significantly shorter than that in the other two groups. The proportion of salivary fistula was higher in the anterograde group (9 cases, 12.9%; P<0.05) compared with that in the other groups. Postoperative facial nerve injury was similar between the middle dissection (1 case, 3.1%) and anterograde groups (3 cases, 4.3%) with lower injury rate compared with the retrograde group (7 cases, 20.6%). The anterograde group had more cases of hypoesthesia of the earlobe (12 cases, 17.1%; P<0.05) than the other two groups. Aesthetic score was higher in the anterograde and middle dissection groups compared with that in the retrograde group (P<0.05).@*CONCLUSIONS@#Midpiece facial nerve dissection is technically feasible and clinically viable in regional parotidectomy.

ABSTRACT

Wendantang (WDT) is a classical traditional Chinese medicine prescription composed of Pinelliae Rhizoma, Bambuseae Caulis in Taenias, Aurantii Fructus Immaturus, Citri Reticulatae Pericarpium, Zingiberis Rhizoma Recens, Glycyrrhizae Radix et Rhizoma, with the effect in regulating Qi-movement and phlegm and relieving stomach and gallbladder. The clinical studies have proved that WDT has significant therapeutic effects on depression, insomnia, schizophrenia, Alzheimer's disease and other nervous system diseases, but wihtout systematic understanding of material basis and compatibility principle because of the complex chemical composition and the scattered research results. Focusing on the neurological diseases and based on the origin of ancient recipes and modern research examples, the author sorted out and summarized the active ingredients constituting the recipe, paid attention to the effect of the compatibility on the composition and efficacy transmission, and judged the rationality of composition intention and selection. On this basis, it comprehensively identifies the potential components and effective paths that can well treat the nervous system diseases, and had the overall understanding about mutual relationship between composition and efficiency. In this article, we expect to find its scientific basis of effective materials and the key technology of quality standards, and define the direction of future research, so as to provide valuable reference for secondary development and new preparations designed of classic prescriptions.

ABSTRACT

Purpose To investigate the clinicopathological features of sinonasal primary secretory carcinoma (SC) and its diagnosis, differential diagnosis. Methods Two cases of sin-nasal SC were analyzed by light microscopy with immunohisto-chemical staining (EnVision) for CK, vimentin, S-100 protein, SOX10, PAS, DPAS, Mamaglobin, Calponin, DOG1, p63 and molecular detection of ETV6 gene break. Results Morphologically, SC revealed varying proportions of solid, tubular, acinar, microcystic, tubular growth patterns. All SC cases were cytological low grade with uniform cells, small-to medium-sizes nuclei, occasional small nucleoli, and abundant pink, bubbly cytoplasm. Mitotic figures were rarely encountered. Tumor cells secreted eosinophilic, colloid-like secretions that were PAS positive. There were no DPAS positive zymogen granules in cyto-plasm. This tumor cells were CK, vimentin, S-100, SOX10, PAS positive and Mamaglobin, Calponin and p63 negative. The ETV6 gene rearrangement was confirmed in all cases by fluorescence in situ hybridization (FISH). After excision, all two patients were survival without tumor recurrence for 41 months and53 months. Conclusion Sinonasal primary SC is a low grade malignant tumor. The histological features of SC are overlap with other salivary gland tumors. Immunohistochemical analysis and FISH are useful for the diagnosis and differential diagnosis.

ABSTRACT

Bromodomain and extraterminal (BET) proteins are a class of proteins that can interpret epigenetic codes and play an important role in regulating gene transcription through identifying and binding acetylated histones or non-histones proteins. The BET inhibitors have emerged with good therapeutic effects in preclinical disease models such as cancer and inflammation. Some of them have entered clinical studies, demonstrating that there is considerable prospect for drug development with BET as a potential therapeutic target. This review briefly describes the structures and functions of the BET proteins, the BET inhibitors in various diseases, as well as molecular mechanisms involved.

ABSTRACT

<p><b>BACKGROUND</b>The sphingosine 1-phosphate (S1P) receptors (S1PRs) are a group of G protein-coupled receptors expressed on the surface of lymphocytes. The interaction between S1P and S1PRs plays a significant role in the migration and distribution of lymphocytes.</p><p><b>OBJECTIVE</b>To investigate the influence of S1PR5 defect on the lymphocytes distribution in mice.</p><p><b>METHODS</b>The distribution of different subsets of lymphocyte in the mice with S1PR5 defect was examined by flow cytometry.</p><p><b>RESULTS</b>Compared with wild type mice, the number of NK cells in the peripheral blood (PB) and spleen (SP) from the mice with S1PR5 defect decreased very significantly 〔PB: 6.4±0.45% vs 2.2±0.47(P<0.01,n=3);SP: 3.0±0.91% vs 0.68±0.14%(P<0.05,n=3)〕. However, the NK cell number in the bone marrow (BM) and lymphonodes (LN) of the mice with S1PR5 defect increased very significantly 〔BM: 0.97±0.20 % vs 2.6±0.35% (P<0.01, n=3); LN: 0.35±0.16% vs 1.7±0.15% (P<0.01, n=3)〕. The percentages of CD3(+) lymphocyte in peripheral blood, spleen and lymph node were not statistically significantly different between these 2 types of mice 〔PB: 17.3±7.9% vs 17.0±4.6% (P>0.05, n=3); SP: 33.0±6.0% vs 27.4±1.8% (P>0.05, n=3); LN: 42.3±10.7% vs 51.2±2.7% (P>0.05, n=3)〕.</p><p><b>CONCLUSION</b>S1PR5 defect can significantly influence the NK cell distribution.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical features and prognosis of patients with myelodysplastic syndrome (MDS) who received allogeneic hematopoietic stem cell transplantation (allo-HSCT).</p><p><b>METHODS</b>A total of 45 patients with MDS and transformed acute myeloid leukemia (tAML) who received allo-HSCT between January 2009 and December 2014 were enrolled in this study. The effects of different conditioning regimens, donor and chemotherapy before transplantation on the clinical outcome were analyzed retrospectively.</p><p><b>RESULTS</b>The median follow-up time for these patients was 54.6 months (ranged from 1 to 72.1 months), the 4-year cumulative overall survival (OS) and disease-free survival (DFS) rates were 77.1% and 62.1%, respectively. In myeloblative conditioning group and reduced intensity conditioning group, the 3-year cumulative OS rate was 69% and 68.6% (HR = 1.0, P = 0.984), respectively, the 3-year cumulative relapse rate was 17.6% and 33.3% (HR = 3.389, P = 0.162). The 100-day cumulative rate of aGVHD (38.6%) in HLA-identical nonsibling group was similar to HLA identical sibling group (37%) (HR = 1.089, P = 0.885); meanwhile the similar 3-year commulative OS rate was achieved in the 2 groups (72.7% and 70%) (HR = 0.952, P = 0.942). Among 26 patients with RAEB-2 and t-AML, the 2-year cumulative OS were 66.7% and 58.3% (HR = 1.265, P = 0.750) and 2-year cumulative relapse rates were 20.0% and 12.5% (HR = 0.417, P = 0.477) in non-chemotherapy and CR post-chemotherapy subgroups. The 1-year cumulative OS rate was 53.5% and 84.8% in the group with or without aGVHD. The patients with aGVHD had higher transplantation related mortality (TRM) compared with patients without aGVHD (HR = 15.0, P =0.011).</p><p><b>CONCLUSION</b>The reduced intensity conditioning doesn't reduce OS rate in patients with MDS, and elderly patients can benefit from it. The OS rate is similar between HLA-identical sibling and HLA-identical nonsibling allo-HSCT. The chemotherapy before transplantation cannot prolong the survival of MDS patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy of mesenchymal stem cells (MSC) in the prevention of graft versus host disease (GVHD) after hematopoietic stem cell transplantation (HSCT).</p><p><b>METHODS</b>Randomized controlled trials (RCT) were identified from PubMed (1950.1-2014.3), EMbase (1970.1-2014.3), Cochrane Central Register of Controlled Trials (CENTRAL, issue 4, 2014) of the Cochrane Library, China Biological Medicine (CBM, 1978.1-2014.3). References of retrieved articles were also identified. The quality of each RCT was evaluated by the Cochrane collaboration's tool for assessing the risk of bias. Data analysis was performed with Review Manager 5.1 to evaluate the efficacy of MSC in the prevention of GVHD after HSCT.</p><p><b>RESULTS</b>A total of 3 English articles involving 117 patients were included. Meta-analysis indicated that MSC did not reduce the incidence of acute GVHD and chronic GVHD (RR:0.44, 95% CI: 0.08 to 2.51, P = 0.35; RR:0.85, 95% CI: 0.54 to 1.33, P = 0.47). However, MSC did not increase occurrence of relapse and cytomegalovirus infection (RR:1.52, 95% CI:0.63 to 3.68, P = 0.35;RR:1.05, 95% CI:0.72 to 1.53, P = 0.78). Finally, MSC did not improve overall survival rate of patients received HSCT (RR:1.06, 95% CI:0.79 to 1.43, P = 0.71).</p><p><b>CONCLUSION</b>MSC may have a preventive effect on GVHD in patients undergoing HSCT. However, the evidence is weak due to the small sample sizes. Thus, a reliable conclusion about the preventive effect of MSC on GVHD at the moment has not been made, further larger, high quality, randomized and controlled trials are warranted.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the value of BCL-2 protein for evaluating the prognosis of patients with diffuse large B cell lymphama (DLBCL).</p><p><b>METHODS</b>The clinical data of 128 patients with DLBCL including clinical features, BCL-2 protein expression, therapeutic outcome and so on were analyzed retrospectively in departenent of hematology, Chinese PLA general hospital from January 2008 to December 2010, and the prognosis of DLBCL patients with different expression levels of BCL-2 protein was compared, including overall survival (OS) and progression-free survival (PFS) rates.</p><p><b>RESULTS</b>The BCL-2 expression postive was found in 83 cases (64.8%), while BCL-2 expression negative was observed in 45 cases (35.2%). The OS rates in BCL-2 expression positive and negative groups were 76.6% vs 76.8% in 3 years (P >0.05), and the PFS rates in BCL-2 expression positive and negative groups were 57.1% vs 70.5% (P >0.05) in 3 years, suggesting that BCL-2 expression level had no significant impact on OS and PFS rates in all DLBCL patients. However, among the older patients aged ≥ 60 years, there was singnificant different of 3 year OS rates in BCL-2 expression positive and negative groups (66.7% vs 76.4%, P >0.05), while 3-year PFS rate in BCL-2 expression positive group was obviosusly lower than that in BCL-2 expression negative group (35.8% vs 83.3%, P < 0.05).</p><p><b>CONCLUSION</b>The positive expression of BCL-2 protein is a poor prognostic factor for older patients aged ≥ 60 years, thus this indicator possesses the prognostic value for these patients with DLBCL.</p>
