To investigate the role of distribution and phylogeny of phenylethanoid glycoside in medicinal plants of Gesneriaceae, five phenylpropanoid glycosides, acteoside, paraboside B, isonuomioside A, paraboside II, and paraboside III were quantitatively determined in 12 species of Gesneriaceae by HPLC. The existence and content of these compounds were analyzed. The results showed that phenylethanoid glycosides were found in the most of those plants, but the kind of phenylethanoid glycosides varied in different species. Acteoside distribute in most of this plant group, paraboside B, isonuomioside A, paraboside II, and paraboside III were rare in those plants. The results of this study support morphological viewpoint that Trib. Trichosporeae is more developmental than Trib. Didymocarpeae.

OBJECTIVETo investigate the effects of X-ray exposure on the release of soluble tumor necrosis factor receptor-p75 (sTNFR-p75) in hepatocellular carcinoma HepG2 cells in vitro.

METHODSEnzyme-linked immunosorbent assay (ELISA) was used to examine the levels of sTNFR-p75 in the supernatants of HepG2 cells before and after X-ray exposure. The cell apoptosis was analyzed by flow cytometry and transmission electron microscope(TEM), and the morphological changes of the cells were examined under optical microscope and transmission electron microscope(TEM).

RESULTSX-ray exposure of the cells resulted in a strong increase of cell apoptosis (P<0.05) and sTNFR-p75 production in the cells as compared with the those before the exposure (P<0.01). Optical microscopy revealed apoptotic changes of HepG2 cell after the exposure, shown as cell shrinkage, spherical cell morphology, cytoplasmic and nuclear condensation. Apoptotic bodies were detected by TEM.

CONCLUSIONX-ray exposure induces HepG2 cells apoptosis by inhibiting the release of sTNFR-p75 into the supernatant.

Objective:To explore the effectiveness of short-term prehabilitation in elderly patients undergoing gastrointestinal tumor surgery.Methods:Elderly patients(139 cases) with gastrointestinal tumors who were admitted to Nanfang Hospital, Southern Medical University for surgery from December 2020 to January 2022 were included through the purposive sampling method, and were divided into the intervention group (69 cases) and the control group (70 cases) according to the patient's wishes using a quasi-experimental research design of non randomized grouped. Routine perioperative nursing was used in the control group, while the short-term prehabilitation was used in the intervention group in addition. The incidence of postoperative complications, the performance indicators, and postoperative functional recovery indicators were analyzed in the two groups.Results:The 6MWD in the intervention group of 1 day and 7 days after the surgery were (460.93 ± 76.36) m and (391.72 ± 72.93) m, which were significant higher than those in the control group, (423.69 ± 72.88) m and (351.13 ± 65.04) m ( t = 8.65, 12.01, both P<0.05). The first exhaust time, first postoperative ambulatory time, the first full fluid intake time and the duration of drainage tube indwelling in the intervention group were (51.28 ± 21.74) h, (33.93 ± 12.50) h, (69.39 ± 29.36) h and (4.30 ± 1.44) d, which were significant lower than those in the control group, (71.51 ± 23.68) h, (47.37 ± 14.58) h, (96.29 ± 38.36) h and (5.35 ± 2.09) d ( t values were -5.83 - -3.44, all P<0.05). Besides, the best critical value of preoperative 6MWD to predict postoperative rehabilitation effect was 477.5 m, with a sensitivity of 68% and specificity of 71%. Conclusions:Short-term prehabilitation improves the perioperative functional reserve and promotes overall functional recovery after surgery to a certain extent, and the postoperative functional recovery effect may be better when the patient′s preoperative 6MWD reaches 477.5 m.

OBJECTIVEUsing pulsed field gel electrophoresis (PFGE) and polymerase chain reaction (PCR) typing to analyze strains isolated from two outbreaks caused by Shigella sonnei and to trace the source of infection.

METHODSVirulence genes ipaH and ial were detected by PCR and PFGE was used to subtype the isolates. Patterns were compared, using the software BioNumerics.

RESULTSWithin the 54 isolates, all were ipaH positive with 48 as ial positive. Strains from the Chongzhou outbreak were clustered into 4 PFGE patterns, with the predominant pattern accounted for 72% of the analyzed strains. The pattern of strains isolated from the cold pork with sauce was identical to the predominant pattern. The strains from Dayi outbreak were clustered into 8 PFGE patterns and the predominant pattern accounted for 56% of the test strains.

CONCLUSIONStrains from the two outbreaks were quite different and the 'cold pork with sauce' seemed to be the major source of infection, causing the outbreak of diarrhea in Chongzhou. The sources of infection of the Dayi outbreak might be complicated whereas PFGE showed a discriminatory and reproducible laboratory tool in the epidemiologic investigation on outbreaks of diarrhea.
