Hodgkin lymphoma (HL) is a type of curable tumor. The treatment strategy of HL is based on staging and risk of recurrence. With the continuous optimization of combined treatment mode, the prognosis of HL has been greatly improved. The predictive value of the prognostic models widely used in HL is lower than before. Therefore, exploring new prognostic factors and enriching existing prognostic models to provide patients with precise and individualized treatment is an important research direction for HL. This article reviews the progress of prognostic factors for HL in recent years.

BACKGROUND: Based on the characteristics of cartilage tissue, such as consisting of single type of cells, the cartilage cells or chondrocyte, absence of blood vessel, rather low consumption level of oxygen and nutrition, low level of allo-immunocompetence and simple function in vivo, it seems to be easy for cartilage cell lines to be established for tissue and cell transplantation. We want to set up a cell line with the purpose of current use in tissue engineering in vitro. It will provide the basis for artificial tissue and organ that will become to be standardized and yielded in batch.OBJECTIVE: To explore the potential stimulatory effects of basic fibroblast growth factor(bFGF) and insulin on the proliferation and differentiation in primary culture mice chondrocytes in vitro. The effect and application of the cell factors will be evaluated for tissue engineering.DESIGN: A grouping controlled and repeated trial was conducted with the cells as the subjects.SETTING: Key laboratory of tissue transplantation and immunology of a college.MATERIAIS: The experiment was completed in the Key Laboratory of Tissue Transplantation and Immunology of the Ministry of Education, Jinan University from November 2002 to May 2003. Cultured cartilage cells at random were obtained as the study objects.METHODS: Mice cartilage cells were cultured in medium at the minimum concentrations of serum. The effects of different concentration of bFGF and insulin on the proliferation and differentiation in mice cartilage cells were observed with WST1 and immunofluorescence staining.MAIN OUTCOME MEASURES: Primary results: ① Effect of bFGF on proliferation of primary cultured mice cartilage cells. ② Effect of insulin on proliferation of primary cultured mice cartilage cells. Secondary results:morphological observation of cartilage cells RESULTS: Primary cultured mice cartilage cells were cultured in medium at the minimum concentration of serum(4 g/L fatal bovine serum). It was found that bFGF and insulin might play an important role on the proliferation and growth of mice cartilage cells in a dose-dependent manner. In addition, morphological observation of cartilage cells showed that both bFGF and insulin not only promoted the proliferation of the cells but also enhanced the matrix secretion of cartilage cells.CONCLUSION: Both bFGF and insulin can stimulate the proliferation of cartilage cells in vitro.

Objective:To explore the changes of neuron-specific enolase (NSE) and S-100β protein (S-100β) during perioperative period in infants undergoing living liver transplantation and examine the effect of brain injury.Methods:From January 2015 to January 2016 in Department of Anesthesiology First Central Clinical College Tianjin Medical University, study group was composed of forty infants of congenital biliary atresia with an age range of (4-12) months, a body weight of (4-10) kg and American Society of Anesthesiologists (ASA) class Ⅲ/Ⅳ. Another 40 infants undergoing general surgery were selected as control group. In study group, blood samples were harvested from central vein pre-operation (T0), before skin incision (T1), 30 min after anhepatic phase (T2), 1 h of neohepatic phase (T3) and 24h after hepato-reperfusion (T4). In control group, blood samples were collected at pre-operation (T0) and 24 h post-operation (T4). Serum levels of S-100β, NSE, heart rate (HR), mean arterial blood pressure (MAP), central venous pressure (CVP) and bispectral index (BIS) were monitored at T1-4 and end of surgery. All children were assessed by Bayley Scale of Infant Development (BSID) at Day 1 pre-operation and 2/4 weeks post-operation for observing mental and motor development status. The results were described with mental development index (MDI) and psychomotor development index (PDI). Pediatric anesthesia emergence delirium (PAED) was employed for evaluating the severity of delirium during the recovery stage at 30 min and 2/4h post-extubation.Results:In study group, serum levels of S-100β and NSE changed significantly during non-hepatic and neohepatic reperfusion phases. After inferior vena cava occlusion, serum concentrations of S-100β and NSE spiked ( P<0.05) and gradually recovered during neohepatic reperfusion period ( P<0.05). No significant inter-group difference existed in serum S-100β or NSE at T4 ( P>0.05). In study group, as compared with Day 1 pre-operation, MDI/PDI decreased at Week 2 post-operation ( P<0.05) and increased from Month 1 post-operation ( P<0.05). Both MDI and PDI were lower than control group before and at Week 2 post-operation ( P<0.05). MDI/PDI of study group basically reached the preoperative level at Month 1 post-operation ( P<0.05). In control group, no significant difference existed in MDI/PDI at Day 1 pre-operation and Week 2/4 post-operation ( P>0.05). In study group, the delirium rate was up to 30% post-extubation and decreased at 2/4h post-extubation. In control group, the incidence of delirium was low at 30 min and 2/4h post-extubation ( P<0.05). Conclusions:Perioperative evaluations of serum levels of NSE and S-100β are significant for predicting the postoperative onsets of delirium and cognitive impairment in children with living donor liver transplantation.

Objective To explore the function of 5-Aza-CdR in B-cell acute lymphocytic leukemia cell line NALM-6 and its influence on the expression of microRNA (miRNA) in the cells. Methods NALM-6 was treated with different concentrations of 5-Aza-CdR. Cell proliferation was detected by methyl thiazolyl tetrazolium (MTT) test, and DNA methyltransferase (DNMT) mRNA expression level was detected by reverse transcription PCR (RT-PCR). The expression changes of miRNA were detected by miScript miRNA PCR Array chip in cells after methylation. Results NALM-6 cell growth was inhibited by different concentrations of 5-Aza-CdR processing time, reaching to the maximum inhibitory rate was (74.163 ±0.381) %. 5-Aza-CdR affected concentrations was inversely proportional with expression level of DNMT mRNA. After 1 000 μmol/L of 5-Aza-CdR was dealed with cell 72 h, the relative expression of DNMT-1 was reduced to 0.453 ±0.021, DNMT-3L was 0.003±0.001, DNMT-3B was 0.395±0.019. MiScript miRNA PCR array sieved out 3 miRNA (miR-184, miR-23a-3p, miR-34a-5p) associated with DNA methylation. Conclusions 5-Aza-CdR down regulates the expression of DNMT gene in NALM-6 cells, and inhibits the proliferation of cells. MiR-184, miR-23a-3p and miR-34a-5p are related to DNA methylation in the occurrence and development of B-cell acute lymphocytic leukemia.

OBJECTIVE: To explore the mechanism of Tiaozhong Granule (TZG), a compound traditional Chinese herbal medicine, in treating rats with mixed reflux esophagitis. METHODS: Fifty-eight SD rats were randomly divided into untreated group (n=12), sham-operated group (n=10), TZG-treated group (n=12), Banxia Xiexin Decoction (BXXXD)-treated group (n=12) and cisapride-treated group (n=12). Mixed reflux esophagitis was induced by esophago-duodenum end-to-side anastomosis. Four weeks later, the rats were orally administered twice daily for 12 days. Pathological changes of esophagus mucous membrane were observed by using HE staining. The expressions of proliferating cell nuclear antigen (PCNA) and p53 in the esophagus tissue were detected by immunohistochemical SABC method. Spectrophotometric method was used to detect the content of malondialdehyde (MDA) and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in serum. RESULTS: Compared with the untreated group, pathological changes of esophagus mucous membrane were relieved in different degrees in TZG-treated group, BXXXD-treated group and cisapride-treated group. Content of MDA and expressions of PCNA and p53 were obviously decreased in the three treated groups (P<0.01), and the activities of SOD and GSH-Px were significantly increased in the three treated groups (P<0.05, P<0.01). TZG had better effects than cisapride in decreasing the content of MDA and increasing the activities of SOD and GSH-Px (P<0.05). TZG was better in aspect of reducing the expressions of PCNA and p53 than BXXXD and cisapride tablets (P<0.05). CONCLUSION: Tiaozhong Granule can treat mixed reflux esophagitis in rats, and its action mechanisms may be associated with decreasing the expressions of PCNA and p53 in esophagus mucous membrane, reducing the content of MDA and increasing the activities of SOD and GSH-Px in serum.
