Malignant lymphoma is a common malignancy. From the perspective of the traditional Chinese medi-cine (TCM), the etiology and pathogenesis of malignant lymphoma are related to dampness, phlegm, toxicity, stasis and deficiency. Basic TCM principles for lymphoma syndrome differentiation and treatment are to strengthen the body resistance and eliminate pathogenic factors. Eliminating dampness, dissolving phlegm, detoxification, dissolv-ing stasis and strengthening body resistance are the principal TCM therapeutic methods for lymphoma treatment. Contemporary TCM physicians have developed Yi-Hua decoction, Zi-Niu powder, Ke-Liu capsule, Wu's Xiao-Liu powder and other herbal formulas, and 37 patents based on Chinese herbs and or herbal components. The effective mechanisms of TCM treatment for lymphoma are involved in inhibiting proliferation, inducing apoptosis, inhibiting angiogenesis, and regulating immune function. There is a great need to study anti-cancer herbs for lymphoma treat-ment.

Objective To study the role of early intravenous nutrition given aggressively combined with early minimal feeding on very low birth weight infants (VLBWI),and to evaluate the clinical value of intestinal barrier protein and MicroRNA.Methods All of 62 cases of VLBWI admitted in NICU,the Maternal and Child Health Hospital of Nantong Affiliated to Nantong University from January 2006 to June 2014 were recruited.Sixty-two VLBWI were randomly divided into group A and group B.Thirty infants in group A were exposed to conventional intravenous nutrition.Thirty-two infants in group B were treated with early intravenous nutrition aggressively combined with early minimal feeding.The time of birth weight recovery,days with intravenous nutrition,hospital stay and complications were recorded.The liver and kidney functions,electrolytes,blood gas analysis were monitored.Enzyme-linked immunosorbent method was used to detect intestinal fatty acid binding protein (Ⅰ-FABP),an intestinal barrier protein in plasma.Infection related MicroRNA155 was detected with fluorescent quantitative polymerase chain reaction (RT-PCR).Results Group B was superior to group A in weight loss after birth [(13.70 ± 3.10) ％ vs (5.46 ± 2.64) ％,P ＜ 0.05],shorter recovery time of body weight [(12.20 ± 3.38) d vs (6.82 ± 3.20) d,P ＜ 0.05],fewer days with intravenous nutrition [(29.62 ± 4.16) d vs (20.80 ± 3.20) d,P ＜ 0.05] and shorter hospital stays [(44.60 ± 6.32) d vs (28.91 ± 4.36) d,P ＜ 0.05].Compared with group A,the infants in group B had less complications,including hyperbilirubinemia (31.2％ vs 56.7％),extrauterine growth retardation (34.3％ vs 73.3％),cholestasis (6.2％ vs 23.3％),feeding intolerance (15.6％ vs 53.3％) and necrotizing enterocolitis (0 vs 16.7％) (all P ＜ 0.05).Although Ⅰ-FABP had a higher plasma concentration in group A than that of group B [(9.083 ± 1.059) μg/L vs (7.563 ± 0.739) μg/L],the difference was not significant (t =1.190,P =0.076 4).However,the plasma levels of Ⅰ-FABP in infants with necrotizing enterocolitis were significantly higher than those of group B [(19.500 ± 3.510) μg/L vs (7.563 ±0.739) μg/L,t =5.231,P =0.035 0].The expression of MicroRNA155 in group A was markedly higher than that of group B (2-△△ct were 0.81 ± 0.12 and 0.24 ± 0.08,respectively,P ＜ 0.05).Conclusions Giving aggressive intravenous nutrition early combined with early minimal feeding was safety and effective to VLBWI,which was of benefit to their growth and development,reducing complications and shorting hospital stays.The detection of intestinal barrier protein Ⅰ-FABP and MicroRNA155 is useful for monitoring feeding complications of VLBWI.

OBJECTIVE: To explore the value of non-invasive prenatal testing (NIPT) for the detection of fetal chromosome copy number variations (CNVs). METHODS: Clinical data of 18 661 pregnant women who underwent NIPT were collected. For fetuses suspected for carrying CNVs, amniotic fluid samples were collected for chromosomal karyotyping and/or chromosomal microarray analysis (CMA). RESULTS: Among all samples, NIPT suggested that 58 fetuses carried trisomy 21, 18 carried trisomy 18, 19 carried trisomy 13, 1 carried trisomies 18 and 21. Eighty eight women accepted invasive prenatal diagnosis. The results of CMA in 59 cases were consistent with those of NIPT, which yielded a consistency rate of 67.05%. In addition, 37 cases of fetal CNVs were detected by NIPT, of which 19 (15 microdeletions and 4 microduplications) have accepted invasive prenatal diagnosis. In 14 cases, the results were consistency with those of NIPT, with a consistent rate of 73.68%. CONCLUSION NIPT features high sensitivity and accuracy. Invasive prenatal diagnosis should be considered for CNVs detected by NIPT, and by tracing its parental origin, it can provide guidance for clinical practice.

Objective:A prospective, multicenter randomized controlled clinical research was conducted to explore the diagnostic value of the new optical staining technology for domestic endoscope, spectral focused imaging (SFI) and variable intelligent staining technology (VIST), for gastric precancerous lesions.Methods:Patients who intended to undergo gastroscopy between August 2020 and May 2021 were randomly divided into the white light group and the new optical staining group at the First Hospital of Hebei Medical University, Shanghai Tenth People's Hospital and the Second Affiliated Hospital of Soochow University. A sequential examination method was applied (white light to new optical staining or new optical staining to white light). The endoscopic diagnostic results and the detection results of Helicobacter pylori ( HP) of the two groups were recorded. At the same time, such five variables as gastric mucosal atrophy, intestinal metaplasia, fold enlargement, nodular gastritis and diffuse redness were evaluated for the risk of gastric cancer in the two groups. Results:A total of 419 cases were enrolled, including 208 cases in the white light group and 211 cases in the new optical staining group. Compared with pathological findings, the detection rates of gastric inflammation, atrophy, intestinal metaplasia, low-grade intraepithelial neoplasia, high-grade intraepithelial neoplasia and advanced cancer lesions in the white light group were 28.9%, 40.4%, 64.9%, 17.8%, 0.5% and 0.5% respectively; while those in the new optical staining group were 30.8%, 42.7%, 62.6%, 15.2%, 2.8% and 0.5%. There were no significant differences in the detection rates between the two groups ( P>0.05). Compared with pathology, the sensitivity, the specificity, the accuracy, the positive predictive value and the negative predictive value for gastric mucosal atrophy in the white light group were 92.9%, 61.3%, 74.0%, 61.9% and 92.7% respectively and those in the new optical staining group (SFI mode) were 94.4%, 64.5%, 77.3%, 66.4% and 94.0% respectively. The above 5 measures for gastric mucosal intestinal metaplasia were 68.1%, 72.6%, 69.7%, 82.1% and 55.2% in the white light group, and 87.1%, 89.9%, 88.2%, 93.5% and 80.7% in the new optical staining group (VIST mode), with significant difference between the two groups ( P<0.05). In terms of HP infection with 13C-urea breath test ( 13C-UBT) results as the gold standard, the above 5 measures were 90.2%, 84.3%, 87.4%, 86.8% and 88.2% in the white light group and 92.6%, 77.1%, 85.4%, 82.2% and 90.1% in the new optical staining group respectively. The proportion of high-risk gastric lesions in the new optical staining group was higher in cases of a gastric cancer risk score≥ 4 ( P<0.05). Conclusion:The new optical staining technology of domestic endoscopy has higher diagnostic value for gastric mucosal intestinal metaplasia. Gastroscopy is helpful for the detection of precancerous lesions with gastric cancer risk score as a tool. The new optical staining technology of domestic endoscopy is similar to imported endoscopy in diagnosing gastric precancerous lesions and HP infection, which is an effective means to detect gastric mucosal precancerous lesions.
