A polyphenolic compound, 1,2,4,6-tetra-O-galloyl-β-D-glucose (1246TGG), was isolated from the traditional Chinese medicine Phyllanthus emblica L. (Euphorbiaceae) and assayed for its potential as an anti-hepatitis B virus (HBV) agent. The cytotoxicity of 1246TGG on HepG2.2.15 as well as HepG2 cells was determined by observing cytopathic effects, and the effects of 1246TGG on secretion of HBsAg and HBeAg in HepG2.2.15 cells were assayed by enzyme immunoassay. Results indicates that treatment with 1246TGG (6.25 μg/mL, 3.13 μg/mL), reduced both HBsAg and HBeAg levels in culture supernatant, yet the inhibitory effects tend to decline with the assay time. This study provides a basis for further investigation of the anti-HBV activity and possible mechanism of action of 1246TGG.

Objective To compare the prognostic value of different inflammation-based prognostic scores and Tumor Node Metastasis ( TNM) stage for patients undergoing radical resection of pancreatic cancer with the routine TNM stage in clinical practice.Methods Clinical data of 185 patients with pancreatic cancer who underwent radical surgery were retrospectively analyzed.Based on the inflammation-based prognostic scores ( Glasgow prognostic score ( GPS ) , neutrophil lymphocyte ratio ( NLR ) , platelet lymphocyte ratio ( PLR) , prognostic nutritional index ( PNI ) and prognostic index ( PI ) ) before surgery, univariate and multivariate analyses were used for identifying influential factors on patients′survival.Homogeneity of different scoring systems was compared using likelihood ratio chi-quare test, and linear trend chi-square test, and receiver operating characteristic ( ROC) curve were performed to compare the differentiating ability and single trend of the selected scores with those of routine TNM stage.Results In univariate analysis, preoperative weight loss, serum C-reactive protein, serum albumin, CA19-9, radical surgery, NLR, PLR, GPS, PI, PNI and TNM stage were all significantly associated with patients′overall survival after surgery (P<0.001).In multivariate cox risk model analysis, TNM stage, radical surgery, GPS, NLR, PLR, PI and PNI were independent risk factors for patients′survival after surgery.ROC curve showed that GPS had higher AUC than other scoring systems, but TNM stage had the highest AUC.The homogeneity, differentiating ability and single trend of GPS were higher compared to other inflammation-based prognostic scores, but those of TNM stage were the highest.Conclusions The inflammation-based prognostic scores like GPS, NLR, PLR, PI and PNI were independent prognostic factors for pancreatic caner patients′survival after surgery, and the prognostic value of GPS was superior to that of NLR, PLR, PI and PNI.

Herpes simplex virus type 1 (HSV-1) is a commonly occurring human pathogen worldwide. There is an urgent need to discover and develop new alternative agents for the management of HSV-1 infection. Tripterygium hypoglaucum (level) Hutch (Celastraceae) is a traditional Chinese medicine plant with many pharmacological activities such as anti-inflammation, anti-tumor and antifertility. The usual medicinal part is the roots which contain about a 1% yield of alkaloids. A crude total alkaloids extract was prepared from the roots of T. hypoglaucum amd its antiviral activity against HSV-1 in Vero cells was evaluated by cytopathic effect (CPE) assay, plaque reduction assay and by RT-PCR analysis. The alkaloids extract presented low cytotoxicity (CC_(50) = 46.6 μg/mL) and potent CPE inhibition activity, the 50% inhibitory concentration (IC_(50)) was 6.5 μg/mL, noticeably lower than that of Acyclovir (15.4 μg /mL). Plaque formation was significantly reduced by the alkaloids extract at concentrations of 6.25 μg/mL to 12.5 μg/mL, the plaque reduction ratio reached 55% to 75% which was 35% higher than that of Acyclovir at the same concentration. RT-PCR analysis showed that, the transcription of two important delayed early genes UL30 and UL39, and a late gene US6 of HSV-1 genome all were suppressed by the alkaloids extract, the expression inhibiting efficacy compared to the control was 74.6% (UL30), 70.9% (UL39) and 62.6% (US6) respectively at the working concentration of 12.5μg/mL. The above results suggest a potent anti-HSV-1 activity of the alkaloids extract in vitro.

Conclusion For non-in-vasived pituitary tumor, microscopic transsphenoidal sugery is safe, convenient, and has no significant difference com-pared with the effect of endoscopic endonasal transsphenoidal approach.

To report the short-term clinical outcome of three cases of distal tibial osteosarcoma treated with a novel 3D-printed ankle fusion prosthesis for limb preservation. The patients were admitted to the Department of Bone Tumor, Shanghai General Hospital from January 2020 to June 2021, with one male and two female cases, aged 18, 12, and 14 years, respectively, all diagnosed with distal tibial osteosarcoma (Ennecking stage IIb). A new self-designed ankle fusion prosthesis was used to perform osteosarcoma resection and prosthetic reconstruction of the distal tibia. The operation time, blood loss, postoperative American Orthopedic Foot and Ankle Society Score (AOFAS) and ankle range of motion were recorded. All the 3 patients successfully completed the operation and were followed up for 22 months, 18 months and 12 months, respectively. The operation time was 140 min, 110 min and 200 min, and the blood loss was 200 ml, 200 ml and 350 ml, respectively. At the last follow-up, the AOFAS were 86, 90 and 95 points, and the range of motion of ankle flexion and extension were 30°, 15° and 30°. There was no local recurrence or lung metastasis at the last follow-up. The novel 3D-printed ankle fusion prosthesis in the distal tibia is safe and effective for the reconstruction of bone defects after resection of osteosarcoma in the distal tibia, and the early postoperative function is satisfactory.

Objective:To explore the effect of long-chain fat emulsion in parenteral nutrition therapy on the perioperative nutritional status of patients with low rectal cancer.Methods:A total of 204 patients who underwent rectal cancer surgery in the Third Hospital of Shanxi Medical University from January 2017 to June 2020 were retrospectively analyzed. The patients were divided into two groups according to the specific nutritional treatment methods, 100 cases in the study group used long-chain fat emulsion for parenteral nutrition support, and 104 cases in the control group used medium- and long-chain fat emulsion injection. After admission, the nutritional status of patients were evaluated according to the results of Scored Patient-Generated Subjective Global Assessment (PG-SGA) and related laboratory tests.
