Object The polysaccharide (CDPS) was isolated, purified and identified from Cistanche deserticola Y. C. Ma, a Chinese materia medica. Methods The polysaccharide was extracted with hot water and precipitated by alcohol. Protein in the precipitates was removed by Sevag method. The products were further purified with column chromatography on DEAE-Sephadex A-50 and Sephacryl S-200. The CDPS was idendified by IR spectrum and UV (200-400 nm) scanning spectrum. Results IR spectrum indicates that there are typical characteristic absorption peaks of polysaccharides. UV scanning spectrum shows that there are no absorption peaks of protein and nucleic acid at point 280 nm and 260 nm. Conclusion The CDPS was identified as homogeneous one.

Objective To observe the MRI findings of normal pancreas in piglets. Methods Eight healthy piglets underwent MR examination, and the morphology, size, signal intensity of pancreas were observed. After MR imaging, all piglets were abdominally incised to observe the anatomy of pancreas and pancreatic adjacent structures. The opening of both common bile duct and pancreatic duct were detected during operation. Two piglets were sacrificed after operation and the whole pancreases were dissected for anatomic research. Results The pancreas of piglets was composed of three parts: right lobe, median lobe and left lobe. All the lobes were displayed clearly on MRI. The signal intensity of pancreas was higher than that of liver and spleen on T1WI, whereas lower than that of liver and spleen on T2WI. On MRCP, pancreatic duct was not presented, whereas the common bile duct could be seen clearly. The opening of common bile duct located at superior part of duodenum (nearby the pylorus) and the opening of pancreatic duct situated at duodenal papilla corresponding to pancreatic right lobe. Conclusion MRI can show the pancreas of piglets very well. The morphology of pancreas and features of common bile duct conjunction with pancreatic duct in piglet are different from those in human.

Purpose: Combinations of immune checkpoint inhibitors (ICIs) and chemotherapy have become the standard first-line treatment for human epidermal growth factor receptor 2 (HER-2)-negative advanced gastric cancer. However, primary resistance remains a challenge, with no effective biomarkers available for its prediction. This retrospective study explores the relationship between the baseline inflammatory burden index (IBI) and primary resistance in such context. Materials and Methods: We analyzed 62 patients with HER-2-negative advanced gastric cancer who received ICIs and chemotherapy as their first-line treatment. The IBI was calculated as follows: C-reactive protein (mg/L) × neutrophil count (10 3 /mm 3 )/lymphocyte count (10 3 /mm 3 ). Based on disease progression within 6 months, patients were categorized into the primary resistant or the control group. We compared baseline characteristics and IBI scores between the groups and assessed the predictive value of the IBI using the receiver operating characteristic curve. Both univariate and multivariate binary logistic regression analyses were conducted to identify factors influencing primary resistance. Results: Nineteen patients were included in the primary resistance group, and forty-three patients were included in the control group. The IBI was significantly higher in the resistant group compared to the control group (P<0.01). The area under the curve for the IBI was 0.82, indicating a strong predictive value. Multivariate analysis identified the IBI as an independent predictor of primary resistance (P=0.014). Conclusions The baseline IBI holds promise as a predictor of primary resistance to combined ICIs and chemotherapy in patients with HER-2-negative advanced gastric cancer.

Objective To explore the underlying mechanism of β2 adrenergic receptor(ADRB2)in fibrogenesis during wound healing.Methods Non-specific ADRB2 gene knockdown adeno-associated virus(AAV-ADRB2 group,6 mice)and control virus(AAV-NC group,6 mice)was injected randomly into the back skin of 12 mice for 21 days,a full-thickness skin defected wound healing murine model was established.Wound healing rates were recorded at the 1st,3rd,5th,and 7th day after operation.Histological examinations by H-E staining,Masson staining,and immunohistochemistry were conducted to observe wounded skin tissue structure,fibrosis,and α-SMA protein expression;quantitative PCR was employed to analyze ADRB2 and matrix metalloproteinase(MMP)mRNA levels;Western blotting was utilized to assess the protein expression levels of COL1A1,COL3A1,TGF-β1,and Smad3.Results On postoperative day 5 and 7,the wound healing rate of the AAV-ADRB2 group significantly decreased(P＜0.05),accompanied by a series pathological changes,including thickened epidermis,exaggerated inflammation,reduced fibroblast count,and inhibited collagen deposition;the α-SMA expression showed a significant decrease(P＜0.05),and the ratio of COL1A1 to COL3A1 decreased(P＜0.05);ADRB2 mRNA levels significantly decreased(P＜0.01),while MMP-1 and MMP-8 mRNA levels increased(P＜0.01);the protein levels of TGF-β1 and Smad3 exhibited a significant decrease(P＜0.05).Conclusions ADRB2 knockdown reduced fibrosis during wound healing and degenerated connective tissue content around the wound bed by inhibiting the TGF-β1/Smad3 signaling pathway,which leads to an increase in MMP mRNA levels and a decrease in the ratio of type Ⅰ to type Ⅲ collagen.

Background: The increasing incidence of radiation?induced osteosarcoma of the maxilla and mandible (RIOSM) has become a signiifcant problem that can limit long?term survival. The purpose of this study was to analyze the associa?tion of clinicopathologic characteristics with treatment outcomes and prognostic factors of patients who developed RIOSM after undergoing radiotherapy for nasopharyngeal carcinoma (NPC). Methods: We reviewed the medical records of 53,760 NPC patients admitted to Sun Yat?sen University Cancer Center during the period August 1964 to August 2012. Of these patients, 47 who developed RISOM and met inclusion criteria were included in this study. Two of these 47 patients refused treatment and were then excluded. Results: For all patients treated for NPC at Sun Yat?sen University Cancer Center during the study period, the total incidence of RIOSM after radiotherapy was 0.084% (47/53,760). Two patients (4.4%) had metastases at the diagnosis of RIOSM. Thirty?nine of the 45 (86.7%) patients underwent surgery for RIOSM; most patients (24/39; 61.5%) who under?went resection had gross clear margins, with 15 patients (38.5%) having either a gross or microscopic positive margin. All patients died. The 1?, 2?, and 3?year overall survival (OS) rates for the entire cohort of 45 patients were 53.3%, 35.6% and 13.5%, respectively. The independent prognostic factors associated with high OS rate were tumor size and treat?ment type. Conclusions: RISOM after radiotherapy for NPC is aggressive and often eludes early detection and timely inter?vention. Surgery combined with postoperative chemotherapy might be an effective treatment to improve patient survival.

The expression of histone lysine-specific demethylase 1 (LSD1) in colorectal cancer cells is increased, and LSD1 is closely related to its occurrence, development, proliferation, invasion and metastasis. LSD1 is a demethylase whose function depends on flavin adenine dinucleoside. It can specifically catalyze the demethylation reaction of histone lysine, and regulate the expression of target genes by reaction of demethyl and dimethyl (H3K4me, H3K4me2, H3K9me, and H3K9me2) at the 4th and 9th positions of lysine H3. Targeted inhibition of LSD1 has been proved to be able to exert significant anti-tumor effect, but since the tumors involve multiple centers and factors, later studies have found that single inhibition of LSD1 cannot completely and effectively kill tumor cells. Moreover, the specificity of the LSD1 catalytic substrate depends to a large extent on the synergistic factors that bind to it and form complexes. The double-target inhibitors based on LSD1 shows more remarkable effect in tumor inhibition. Therefore, finding the combined synergistic factors of LSD1 may provide the basis for the research of multi-target inhibitors.

IgA nephropathy (IgAN) is one common type of glomerulonephritis caused by a deposition of immune complexes in mesangium and partial capillary loops. It is also an important risk factor for end-stage renal disease (ESRD). Kidney transplantation (KT) has been an ultimate treatment for IgAN patients progressing into ESRD. However, there is still a high risk of recurrence after transplantation. Currently no effective treatment is available for recurrent IgAN. This review summarized the latest researches of managing IgAN recurrence after KT, such as optimal treatment, immunosuppression, complement therapy and surgery.
