Abstract
Objective: To analyze the correlation between the histological classification of hepatocellular carcinoma (HCC), especially macrotrabecular-massive (MTM), tumor invasiveness, and prognosis. Methods: The clinical and follow-up data of 246 consecutive HCC cases who met the inclusion criteria from 2015 to 2018 were retrospectively analyzed. They were divided into trabecular/pseudoglandular, trabecular/patchy, and MTM types according to the histological classification. The relationship between each type and related clinicopathological features was analyzed. The Kaplan-Meier method was used to plot tumor-free survival (DFS) and overall survival (OS) curves. Log rank tests, COX univariate, and multivariate regression analyses were conducted to analyze the relationship between clinical features, including histological classification, DFS, and OS. Results: Trabecular/pseudoglandular, trabecular/nodular, and MTM type proportions were 44.7% (110 cases), 32.9% (81 cases), and 22.4% (55 cases), respectively. The results of the clinicopathological features showed that MTM-type HCC was significantly more invasive than the other two types, with alpha-fetoprotein (AFP) ≥400 ng/ml, tumor diameter≥8 cm, no tumor capsule, poor differentiation, and MVI positivity proportions, and the differences were statistically significant (P < 0.05).The proportion of MTM-type HCC patients with American Joint Committee on Cancer TNM Stage III to IV and Chinese Liver Cancer Staging (CNLC) II to II was significantly higher than that of the first two types, and the differences were statistically significant (P < 0.05). In addition, the proportion of MTM subtypes undergoing transcatheter arterial chemoembolization was also raised (P < 0.05). The DFS and OS were significantly lower for MTM-type HCC compared to trabecular/pseudoductal-type HCC at 1-, 3-, and 5-years, and the differences were statistically significant (P < 0.05). Univariate analysis indicated that strongly invasive clinical pathological features such as alpha fetoprotein (AFP) ≥400 ng/ml, tumor diameter ≥ 8 cm, no tumor capsule, poor differentiation, positive microvascular invasion, tumor stage, and MTM staging were all risk factors affecting DFS and OS (P < 0.05). Multivariate COX analysis showed that MTM histological staging, AFP ≥ 400 ng/ml, tumor non-encapsulation, satellite nodules, CNLC stages II~III, and TNM stages III~IV were independent risk factors for DFS (P < 0.05), while AFP ≥ 400 ng/ml, tumor non-encapsulation, and CNLC stage II~III were independent risk factors for OS ( P < 0.05). Conclusion: Histological classification is highly correlated with tumor invasiveness and HCC prognosis. Trabecular/pseudoglandular types have lower malignancy and a better prognosis, while MTM types exhibit strong invasive features and a poor prognosis.

Abstract
Objective: To investigate the efficacy and safety of a new endoscopic anastomosis clip in the treatment of defects after endoscopic full-thickness resection (EFTR). Methods: Retrospective cohort study. Fourteen patients [4 males and 10 females, aged (55.9±8.2) years (45-69 years)] with gastric submucosal tumors underwent EFTR at the First Affiliated Hospital of Soochow University were included from December 2018 to January 2021. Patients were divided into new anastomotic clamp group (n=6) and nylon ring combined with metal clips group (n=8). Preoperative endoscopic ultrasound examinations were required to all patients to evaluate the wound condition. The size of the defect, operation time required for wound closure, success rate of closure, postoperative gastric tube placement time, postoperative hospital stay, incidence of complications, preoperative and postoperative serological indexes were compared between the two groups. All patients were followed up after the operation, among which the general endoscopy was reviewed in the first month after the operation, and the telephone and questionnaire follow-up were used in the second, third, sixth month and one year after the operation to evaluate the therapeutic effect of the new endoscopic anastomosis clip and nylon rope combined with metal clip after the EFTR operation. Results: Both groups successfully completed EFTR and were successfully closed. There was no significant difference between the age, tumor diameter and defect diameter of the two groups (all P>0.05). Compared with the nylon ring combined with metal clip group, the operation time of the new anastomotic clip group was shortened [(5.0±1.8) minutes vs (35.6±10.2) minutes, P<0.001]. The operation time was shortened [(62.2±12.5) minutes vs (92.5±0.2) minutes, P=0.007]. Postoperative fasting time decreased [(2.8±0.8) days vs (4.9±1.1) days, P=0.002]. The hospital stay after operation was also shortened [(5.2±0.8) days vs (6.9±1.5) days, P=0.023]. The total intraoperative bleeding volume decreased [(20.00±5.48) ml vs (35.63±14.75) ml, P=0.031]. The patients in both groups received endoscopic examination 1 month after operation, and there was no delayed perforation and bleeding after operation. There was no obvious symptoms of discomfort. Conclusion: The new anastomotic clamp is suitable for the treatment of full-thickness gastric wall defects after EFTR, and shows advantages of shorter operation, less bleeding, and fewer postoperative complications.

Abstract
Acute myeloid leukemia (AML) with NPM1 mutation is a distinct genetic entity with favorable outcomes. Nevertheless, emerging evidence suggests that NPM1-mutated AML is still a highly heterogeneous disorder. In this study, 266 patients with AML with NPM1 mutations were retrospectively analyzed to evaluate the associations between variant allele frequency (VAF) of NPM1 mutations, co-mutated genes, measurable residual disease (MRD), and patient outcomes. Multiparameter flow cytometry (MFC) and real-time quantitative polymerase chain reaction (RT-PCR) were used for monitoring MRD. Ultimately, 106 patients were included in the long-term follow-up period. Patients with high NPM1 VAF (≥ 42.43%) had poorer 2-year relapse-free survival (RFS) (55.7% vs. 70.2%, P = 0.017) and overall survival (OS) (63.7% vs. 82.0%, P = 0.027) than those with low VAF. DNMT3A mutations negatively influenced the outcomes of patients with NPM1 mutations. Patients with high DNMT3A VAF or NPM1/DNMT3A/FLT3-ITD triple mutations had shorter RFS and significantly lower OS than that in controls. After two cycles of chemotherapy, patients with positive MFC MRD results had lower RFS (MRD+ vs. MRD-:44.9% vs. 67.6%, P = 0.007) and OS (61.5% vs. 76.6%, P = 0.011) than those without positive MFC MRD results. In multivariate analysis, high NPM1 VAF (hazard ratio [HR] = 2.045; P = 0.034) and positive MRD after two cycles of chemotherapy (HR = 3.289; P = 0.003) were independent risk factors for RFS; MRD positivity after two cycles of chemotherapy (HR = 3.293; P = 0.008) independently predicted the OS of the patients. These results indicate that VAF of both NPM1 gene itself or certain co-occurring gene pre-treatment and MRD post-treatment are potential markers for restratifying the prognoses of patients AML having NPM1 mutations.

Abstract
目的 分析CD7在初治急性髓系白血病(AML)患者中的表达和预后价值,进一步探讨CD7表达情况与CEBPA突变的相关性,明确其在CEBPA野生型和突变型AML患者中与预后的关系。 方法 回顾性分析2010年1月至2016年12月收治的298例初治AML患者(除外M3亚型)的临床资料,在全部患者以及CEBPA野生型和突变型组中,分别比较CD7阳性(CD7+)和CD7阴性(CD7−)患者的临床特征及预后差异,并联合CD7表达情况和CEBPA突变状态初步建立新的危险分层模型。 结果 在CD7+组中,CEBPA单位点和双位点突变的发生率分别为10.1%和33.9%,显著高于CD7−组(5.3%和4.2%),差异具有统计学意义(P=0.000)。在CEBPA野生型患者中,CD7+组患者相较CD7−组患者完全缓解率低(P=0.001)、复发率高(P=0.023),而两组总生存(OS)期和无病生存(DFS)期差异无统计学意义(P值均>0.05);在CEBPA突变患者中,CD7+组显示有更长的OS期(P=0.019)和DFS期(P=0.010)。根据CD7表达和CEBPA突变与否将AML患者分为三个亚组:CD7+伴CEBPA突变组、CD7−组和CD7+伴CEBPA野生型组。三组患者的3年OS率分别为80.2%、48.0%和30.6%(P<0.001),3年的DFS率分别为74.1%、37.4%和22.2%(P<0.001)。 结论 CD7+组中CEBPA突变率显著高于CD7−组,CD7+在CEBPA野生型组和突变组AML中存在截然相反的预后意义。根据CD7表达情况和CEBPA突变与否建立新的危险分层模型,有助于指导临床个体化治疗。

Abstract
Objective: To evaluate efficacy of the BiRd regimen, a combination of clarithromycin, lenalidomide, and dexamethasone, in the treatment of patients with relapsed/refractory multiple myeloma (RRMM) . Methods: Patients with RRMM treated with BiRd between September 11, 2013 and August 1, 2016 at six centers were included to evaluate overall survival rate (ORR) , clinical benefit rate (CBR) , progression-free survival (PFS) , overall survival (OS) , as well as adverse events. Results: Of 30 patients with RRMM, 27 patients were evaluable, and ORR and CBR were 51.9% (14/27) and 66.7% (18/27) respectively, including 1 sCR (3.7%) , 3 CR (11.1%) , 3 VGPR (11.1%) , and 7 PR (25.6%) . In 13 patients with prior Rd, ORR and CBR were 38.5% (5/13) and 61.5% (8/13) respectively, of which 5 patients with ≥MR carried high-risk cytogenetic[ (e.g.17p- or t (4;14) ] together with at least one of other adverse-prognostic cytogenetic (e.g.13q- and/or 1q21+) . In 24 patients with prior bortezomib-based therapy, ORR and CBR were 45.8 and 62.5%, respectively. With a median follow-up time of 14.9 (range 1.0-33.8) months, the median PFS and OS were 12.0 (95%CI 11.6-12.4) and 27.6 (95%CI 15.1-40.1) months, respectively. The BiRd regimen was well tolerated. Conclusion: The BiRd regimen is an effective and safety protocol for RRMM, including those carrying high-risk cytogenetic markers.

Abstract
In this paper, a logistic-function-based nonlinear companding transform (LNCT) is proposed to reduce the peak-to-average power ratio of asymmetrical hybrid optical orthogonal frequency division multiplexing (AHO-OFDM) signals in visible light communications (VLC). First, the positive and negative amplitudes of the bipolar AHO-OFDM signal are divided into two groups as the positive and nonnegative groups. Then, a peak detection is employed frame-by-frame to locate the group where the maximum peak occurs. Finally, the piecewise companding transform consisting of the nonlinear logistic function and a linear function is performed on the amplitude groups with and without the maximum peak, respectively. The simulation results show that the proposed LNCT scheme outperforms the classical linear nonsymmetrical transform method in terms of the complementary cumulative distribution function with a competing bit error rate performance, thus demonstrating its application potential in AHO-OFDM-based VLC systems.

Abstract
The aim of this study was to profile the spectrum of genetic mutations in acute myeloid leukemia (AML) patients co-occurring with CEBPA double mutation (CEBPAdm). Between January 1, 2012, and June 30, 2017, 553 consecutive patients with de novo AML were screened for CEBPA mutations. Out of these, 81 patients classified as CEBPAdm were analyzed further by a sensitive next-generation sequencing assay for mutations in 112 candidate genes. Within the CEBPA gene itself, we found 164 mutations. The most common mutated sites were c.936_937insGAG (n = 11/164, 6.71%) and c.939_940insAAG (n = 11/164, 6.71%), followed by c.68dupC (n = 10/164, 6.10%). The most common co-occurring mutations were found in the CSF3R (n = 16/81, 19.75%), WT1 (n = 15/81, 18.52%), and GATA2 (n = 13/81, 16.05%) genes. Patients with CSF3R mutations had an inferior four-year relapse-free survival (RFS) than those with the wild-type gene (15.3% versus 46.8%, respectively; P = 0.021). Patients with WT1 mutations had an inferior five-year RFS compared with those without such mutations (0% versus 26.6%, respectively, P = 0.003). However, GATA2, CSF3R, WT1 mutations had no significant influence on the overall survival. There were some differences in the location of mutational hotspots within the CEBPA gene, as well as hotspots of other co-occurring genetic mutations, between AML patients from Chinese and Caucasian populations. Some co-occurring mutations may be potential candidates for refining the prognoses of AML patients with CEBPAdm in the Chinese population.

Abstract
CCAAT/enhancer binding protein alpha gene (CEBPA) is an important transcription factor in maintenance of differentiation of granulocyte series of hematopoietic system. It plays a key role in regulating cell proliferation and differentiation. CEBPA mutation easily occurs in M1 and M2 type of acute myeloid leukemia, about 5%-14% in adult acute myeloid leukemia and 7.9% in children with acute myeloid leukemia. At present, domestic CEBPA mutation research is far less than abroad. This review focuses on the structual characteristics and detection method of CEBPA, CEBPA clinical features, the effect of CEBPA mutation on the prognosis of patients and the choice of treatment.

Abstract
AIM To investigate the effect of triacetylshikimic acid (TSA) on the platelet adhesion to neutrophils and P-selectin expression on activated platelet membrane induced by thrombin and reperfusion after focal cerebral ischemia. METHODS The platelet adhesion to neutrophils was evaluated by rosette assay, and P-selectin expression on platelet membrane was determined by flow cytometry. RESULTS TSA 10 - 1000 micromol/L markedly inhibited thrombin(0.4 kU/L)-induced platelet adhesion to neutrophils. The platelet adhesion to neutrophils induced by a 21-h reperfusion after middle cerebral artery occlusion for 3 h was also inhibited in a dose-dependent manner by TSA 50 - 200 mg/kg given by ig immediately and at 60 min again after the onset of cerebral ischemia. TSA was also shown to decrease the P-selectin expression on platelet surface induced by thrombin in washed platelet and by adenosine diphosphate (ADP) 5 micromol/L in whole blood. CONCLUSION Reperfusion after cerebral ischemia and thrombin induced platelet adhesion to neutrophils, which could be reduced by TSA probably due to its inhibition of P-selectin expression on activated platelets.

Abstract
AIM To study the effects of shikimic acid (SA) on focal cerebral ischemic injury after middle cerebral artery thrombosis (MCAT). METHODS Thrombosis was induced by FeCl3 in middle cerebral artery of rats. The influences of SA on neurologic deficit (ND), infarct size (IS), brain edema, and cerebral blood flow (CBF) in ischemic region were observed. RESULTS SA 25 and 50 mg.kg-1 i.p. for 3 d before MCAT attenuated ND, and reduced IS by 51% and 42%; and decreased brain water content from 80.7% to 79.8% and 79.9%; and increased CBF after ischemia from 50.2% of the preischemic level to 75.5% and 73.3%, respectively. In pathologic examination, there was much less thrombosis in MCA in the rat with the pretreatment by SA 25 mg.kg-1. The extent of brain ischemia was much less than that of control. CONCLUSIONS SA reduced focal cerebral ischemic injury induced by middle cerebral artery thrombosis.

Abstract
OBJECTIVE To observe the Sijunzi Decoction in rectifying the digestive disorder. METHODS Sijunzi decoction (SJZD) was chosen to treat digestive dysfunction in mice. The model was induced by Xiaochengqi decoction and semi-starvation. The effects on the absorptive function of the small intestine, body weight, autonomous activity levels, oxidative phosphorylation of hepatic mitochondrion, respiratory control rate (RCR) and cells energy charge were observed in vivo. RESULTS The group given Xiaochengqi decoction had lower absorption, decreased body weight, and lower autonomous activity levels, and their hepatic mitochondrion RCR and cell energy charge were also lower than those of the control group. The figures for the group given SJZD all showed improvement, especially the group given the larger dose of SJZD. CONCLUSION SJZD could correct Deficiency of the Spleen and Stomach which to some extent is caused by digestive dysfunction. So it is considered that the Spleen's function of transportation and transformation includes two meanings: external transportation and transformation--the digestive and absorptive function of the small intestine, and internal transportation and transformation--the liver's conversion of nutrients and generate energy (ATP).

Abstract
The exponent eta for the temperature dependence of the self-broadening coefficient of carbon monoxide has been measured directly using a tunable diode laser spectrometer. For lines of (12)C(16)O between P(25) and P(31), the exponent has a value of 0.66 +/- 0.05. For the P(13) and P(16) lines of (13)C(16)O, the exponent appears to be the same. These results show that the value of eta is less than the generally accepted value of 0.75 for temperatures between ambient and 180 degrees C.
