Objective:To investigate the clinical efficacy of lenalidomide combined with bortezomib and dexamethasone (RVd) regimen in treatment of newly diagnosed multiple myeloma (NDMM) patients and its effect on the levels of regulatory T cells (Treg cells) and natural killer (NK) cells.Methods:Thirty-eight NDMM patients who were admitted to the Second Affiliated Hospital of Bengbu Medical College from September 2019 to May 2022 were selected for a prospective study, and were divided into control group (18 cases) and observation group (20 cases) according to random number table method. The control group was treated with bortezomib+epirubicin+dexamethasone (VAd) regimen, and the observation group was treated with RVd regimen. The efficacy and safety were compared between the two groups. The levels of Treg cells (CD4 + CD25 + FOXP3 +) and NK cells (CD3 - CD56 + CD16 +) before and after treatment in the two groups were detected by flow cytometry, and the results were compared. Results:After 4 courses of treatment, the objective response rate (ORR) of the observation group was 95.0% (19/20), which was higher than that of the control group [77.8% (14/18)], and the difference was statistically significant ( P = 0.016). Before treatment, there was no statistical difference in the levels of Treg cells and NK cells between the two groups ( P values were 0.381 and 0.650). After treatment, the level of Treg cells in the control group increased from (1.5±0.5)% before treatment to (4.7±1.3)% ( P = 0.008), while the level of Treg cells in the observation group increased from (1.4±0.5)% before treatment to (6.8±1.5)% ( P = 0.001), and the level in the observation group was higher than that in the control group ( P = 0.027); the level of NK cells in the control group increased from (16±6)% before treatment to (20±5)% ( P = 0.004), while the level of NK cells in the observation group increased from (16±6)% before treatment to (24±6)% ( P = 0.006), and the level in the observation group was higher than that in the control group ( P = 0.032). The incidence rates of thrombocytopenia and neutropenia in the observation group were higher than those in the control group, and the differences were statistically significant ( P values were 0.012 and 0.027), which was reversible after active treatment. There was no statistical difference in the incidence rates of other adverse reactions (all P>0.05). Conclusions:RVd regimen for NDMM is clinically effective, safe and reliable, and the patients' levels of Treg cells and NK cells elevate after treatment.

Objective:The decision tree Chi-square automatic interactive detection (CHAID) algorithm and binary Logistic regression analysis were used to construct the risk prediction model of premature ovarian failure (POF) in patients with uterine fibroids complicated with hypertension after surgery, and the results of the risk prediction model were compared and analyzed.Methods:Patients with uterine fibroids complicated with hypertension admitted to Taizhou Hospital of Zhejiang Province from Jan. 2019 to Sep. 2022 were retrospectively analyzed as the research objects. CHAID algorithm and Logistic regression analysis were used to establish risk prediction models, respectively. The area under the curve (AUC) of receiver operating characteristic curve (ROC) was used to compare and evaluate the prediction effects of the two models.Results:A total of 860 patients were collected, including 56 patients with premature ovarian function failure after operation, and the incidence of premature ovarian function failure was 6.51%. CHAID method and Logistic regression analysis showed that uterine myoma surgery, hypertension, smoking or passive smoking, family history of premature ovarian failure, sleep status, physical exercise and history of induced curettage were important influencing factors of premature ovarian failure. The accuracy of risk prediction of decision tree model was 88.2%, and the fitting effect of the model was good. The Logistic regression model Hosmer-Leme-show goodness of fit test showed that the model fit was good. The AUC of Logistic regression model was 0.893 (95% CI: 0.862-0.899), and the AUC of decision tree model was 0.882 (95% CI: 0.856-0.899). The predictive value of the two models was moderate, and there was no significant difference between them ( Z=0.254, P>0.05) . Conclusions:The combination of decision tree and Logistic regression model can find the influencing factors of premature ovarian function failure in patients with uterine fibroids complicated with hypertension after operation from different levels, and the relationship between the factors can be more fully understood. The establishment of a risk model for premature ovarian function failure in patients with uterine fibroids complicated with hypertension after surgery can provide a reference for postoperative intervention in patients with uterine fibroids complicated with hypertension, and more effectively help patients actively prevent and slow down the occurrence and development of POF.

Objective:To design a pediatric early warning score (PEWS) ruler and observe the effect of its application in the nursing of critically ill children hospitalized in neurology department.Methods:A total of 200 critically ill children admitted to Department of Neurology of Hunan Children′s Hospital from 2018 to 2019. 98 cases who were hospitalized from January to September 2019 were selected as the observation group, and 102 cases who were hospitalized from January to September 2018 were set as the control group. The control group received conventional care, while the observation group conducted PEWS ruler for nursing intervention on the basis of conventional care. The differences in hospital days, ICU transfer rate, and frequency of medical intervention between the two groups were compared.Results:The hospital days of the control group and observation group were 18.17 ± 6.33 and 13.33 ± 6.38 respectively, and the difference between the two groups was significant ( t=5.38, P<0.01). The ICU transfer rate was significantly different between the control group 17.6% (18/102) and observation group 8.2% (8/98) ( χ2=3.98, P<0.05). The reduction of increased intracranial pressure, cooling, calm, sedation and oxygen breathing in the control group were 6.86% (7/102), 13.73% (14/102), 6.86% (7/102), 7.84% (8/102), while the observation group were 17.35% (17/98), 27.55% (27/98), 24.49% (24/98), 28.57% (28/98), and the differences between the two groups were significant ( χ2 values were 5.20-14.55, all P<0.05). Conclusions:The application of PEWS ruler is helpful for nurses to recognize the progress of diseases of the critically ill children. Also, it can shorten the hospitalization days of these children, reduce the ICU transfer rate, as well as improve the nursing quality for them.

Neuromyelitis optica spectrum disorders (NMOSD) are a severe autoimmune inflammatory demyelinating disease of the central nervous system. NMOSD complicated with immune thrombocytopenia (ITP) is rare. This paper reports a case of NMOSD who was misdiagnosed as multiple sclerosis for many years, and then developed thrombocytopenia. ITP was diagnosed by perfect examination. After immunosuppression and thrombopoiesis therapy, the platelets returned to normal. The review of the case and literatures can help to improve the understanding of this kind of disease, timely diagnose and treat patients, and avoid serious complications.

Tung tree (Vernicia fordii) is an economically important woody oil plant that produces tung oil rich in eleostearic acid. Here, we report a high-quality chromosome-scale genome sequence of tung tree. The genome sequence was assembled by combining Illumina short reads, Pacific Bio-sciences single-molecule real-time long reads, and Hi-C sequencing data. The size of tung tree gen-ome is 1.12 Gb, with 28,422 predicted genes and over 73％ repeat sequences. The V. fordii underwent an ancient genome triplication event shared by core eudicots but no further whole-genome duplication in the subsequent ca. 34.55 million years of evolutionary history of the tung tree lineage. Insertion time analysis revealed that repeat-driven genome expansion might have arisen as a result of long-standing long terminal repeat retrotransposon bursts and lack of efficient DNA deletion mechanisms. The genome harbors 88 resistance genes encoding nucleotide-binding sites;17 of these genes may be involved in early-infection stage of Fusarium wilt resistance. Further, 651 oil-related genes were identified, 88 of which are predicted to be directly involved in tung oil biosynthesis. Relatively few phosphoenolpyruvate carboxykinase genes, and synergistic effectsbetween transcription factors and oil biosynthesis-related genes might contribute to the high oil content of tung seed. The tung tree genome constitutes a valuable resource for understanding genome evolution, as well as for molecular breeding and genetic improvements for oil production.

Objective:To investigate the clinicopathological differences in laterally spreading tumor (LST) from the rectum and colon.Methods:Clinicopathological records of 198 patients with LST (116 cases in rectum,82 cases in colon) from the Second Xiangya Hospital of Central South University between January 2012 and January 2017 were evaluated.Results:A total of 198 colorectal LST were included.According to the endoscopic classification,nodular mixed type (LST-GM),homogeneous type (LST-GH),flat elevated type(LST-FE) and pseudodepressed type (LST-PD) were 127(64.1％),13(6.6％),41(20.7％) and 17(8.6％),respectively.LST-GM was predominant in the rectum (71.7％),while LST-FE was predominant in the colon (78.0％),with significant difference (P＜0.01).The mean size of LST was (52.03±35.62) mm or (25.37±11.56) mm in the rectum or the colon,with significant difference between them (P＜0.01).High grade intraepithelial neoplasia frequency was higher in the rectum than that in the colon (31.0％ vs 18.3％),while the low grade intraepithelial neoplasia frequency was lower in the rectum than that in the colon (61.2％ vs 75.6％) (both P＜0.05).The mean size of LSTGM and LST-GH diameter were larger in the rectum than that in the colon,and the malignant potential of LST-GM was higher in the rectum than that in the colon.The percentage of high grade intraepithelial neoplasia + invasive carcinoma was 41.8％ and 22.2％,respectively (both P＜0.05).LST in colon was mostly treated with endoscopic mucosal resection,while LST in rectum was treated by endoscopic submucosal dissection predominantly.Conclu sion:LSTs from the rectum and colon show different clinicopathological characteristics to some extent.LST-GM is predominant in the rectum,while LST-FE is predominant in the colon.The malignant potential of LST-GM is higher in the rectum than that in the colon.

To compare the safety and efficacy between endoscopic submucosal dissection (ESD) and radical surgery (RS) for the treatment of large colorectal laterally spreading tumors (LST) larger than 50 mm in diameter. 
 Methods: From January 2011 to January 2016, a total of 82 patients were diagnosed as large LST without deep submucosal invasion (T1 SM2, ≥1 000 µm) in the Second Xiangya Hospital of Central South University. Among them, 52 patients were treated by ESD and the other 30 patients were treated by RS [laparoscopic-assisted colectomy (LAC)/open colectomy (OC)]. The clinic data were retrospectively analyzed and the en-bloc resection rate, en-bloc R0 resection rate, local recurrence, complication, procedure time and hospital stay were collected and analyzed.
 Results: The lesion sizes were (5.80±1.20) cm and (5.53±0.69) cm in diameter for ESD and RS groups, respectively (P>0.05). En-bloc resection rates, en-bloc R0 resection rates and recurrence rates showed no significant difference between the ESD group and RS group (P>0.05). Complication rate of the ESD group (7.69%, 4/52) was much lower than that in the RS group (33.33%, 10/30; P<0.01). The ESD group also had a shorter hospital stay and operation time than the RS group (P<0.05).
 Conclusion: ESD appears to be a safe, minimal invasive and effective strategy for treating large LST and it is obviously better than RS in the aspects of hospital stay, operation time and short-term complication.

Objective: To analyze the information of patients with acute myocardial infarction (AMI) in a single center during last 6 years, and to distinguish the clinical differences of patients between TakoSTubo cardiomyopathy (TTC) and ST-segment elevation myocardial infarction (STEMI). Methods: A total of 1042 consecutive patients with primarily diagnosed acute anterior ST-segment elevation (STEMI) admitted in our hospital from 2008-01 to 2014-04 were retrospectively enrolled. The relevant patients were studied in 2 groups:TTC group, the patients with coronary angiography (CAG) and the contrast study of left ventricle corrected TTC diagnosis, n=10, and STEMI group, the patients received CAG within 6 hours of on set with conifrmed left anterior descending singlevessel disease at the same period of time as TTC patients,n=32. The basic clinical characteristics, levels of blood lipids, MI related biomarkers, the incidence rate of pathological Q wave, QTc interval and negative T wave in 12-lead ECG were compared between 2 groups. Results: The percentage of corrected TTC diagnosis in patients with primarily diagnosed STEMI was 1.06%. The female gender in TTC group and STEMI group was 100% vs 9%,P<0.01, TTC group had more patients with stress history before on set than that in STEMI group (70% vs 22%,P=0.02), lower levels of MI related biomarkers as CK (486 ± 249) U/L vs (716 ± 132) U/L, CK-MB (13.5 ± 17.1) mg/L vs (47.5 ± 21.9) mg/L, cTnI (22.8 ± 16.3) ng/mL vs (56.4 ± 24.0) ng/mL, allP<0.01. The age of morbidity, the ratios of hypertension, diabetes mellitus and blood lipids were similar between 2 groups. The frequency of abnormal Q-wave in ECG was similar between 2 groups, while the QTc interval was different in TTC group and STEMI group (630 ± 117) ms vs (540 ± 62) ms,P=0.001, the negative T waves in ECG leads II, III, aVF, aVR and V6 were as (100.00% vs 3.13%), (60.00% vs 6.25%), (90.00% vs 3.13%), (100.00% vs 21.88%), (100.00% vs 46.88%), allP<0.05. Conclusion: TTC patients with the main presentation as ST-segment elevation are usually having emotional or physical stress before on set, with obviously prolonged QTc interval and more frequency of negative T waves in ECG.
