Objective To evaluate the effects of perioperative rehabilitation for patients with self-forearm internal arteriovenous fistula.Methods Divided 124 patients with end-stage renal disease into the functional training group (65 cases,A group)and the control group(59 cases,B group) randomly,and then compared certain related indexes between the two groups.Results In the A group,the artery diametcr was obvious widen before functional training without operation,and the vein diameter was obvious widen before functional training without operation too,P ＜ 0.05.After operation,the A group Anastomotic unobstructed was obviously better than B group in one-stage,P ＜ 0.05.A group with thrombosis cases significantly less postoperative than B group,P ＜ 0.05.A group with edema of hands was significantly shorter than B group,P ＜ 0.01.Postoperative fistula time to maturity in the A group was (43.76 ± 2.21) days,which was significantly shorter than that of in the B group,(49.69 ± 5.85) days,P ＜ 0.01.Conclusion Systematic strengthening of perioperative functional exercises can significantly improve preoperative vascular conditions,improve the success rate of operation,reduce risk of thrombosis cases,shorten the time of hand edema and the time of fistula in mature.

To discover an efficient strategy for the conversion of the antibacterial activity of fluoroquinolones into the antitumor activity, the three series of C-3 s-triazole-based derivatives including sulfide ketones (6a-6g), thiosemicarbazones (7a-7g) and fused heterocyclic thiazolotriazoles (8a-8g) were synthesized from ciprofloxacin (1), respectively. The structures were characterized by elemental analysis and spectral data. The antitumor activity was tested against three tumor cell lines (Hep-3B, Capan-1 and HL60) using the MTT assay. The three types of compounds all exhibited stronger anti-proliferative activities than ciprofloxacin in the test. The order of their activities was in compounds 7>8>6, and the order of selectivity against cancer cell lines was Capan-1, Hep-3B and HL60. Meanwhile, the SAR revealed that some compounds with electron-drawing group substituted such as fluoro- and nitro-phenyl compounds (6f, 7f, 8f) and (6g, 7g, 8g) displayed more significant activity than the control compounds, especially the IC50 values of thiosemicarbazone compounds 7f and 7g against Capan-1 was comparable to doxorubicin. Thus, a five-membered triazole as the C-3 bioisostere modified with the functionalized side-chain of sulfide-ketone thiosemicarbazone warrants special attention and further investigation.

To search for fluoroquinolones(FQs)with antitumor activity;the C-3 carboxylic acid group of peflox-acin (1)was replaced by fused heterocyclic core;and twelve novel thiazolo[3;2-b][1;2;4]triazole heterocycles(6a-6l)were designed and synthesized.The structures of target compounds were characterized by elemental anal-ysis and spectral data.The results of the in vitro antiproliferative effect on SMMC-7721;L1210 and HL60 cell lines showed that the title compounds exhibited more significant antitumor activity than both of the pefloxacin and the corresponding opening-ring intermediates(5 a-5 l).Among them;the target compounds which possess a ben-zene ring bearing a hydroxyl group (6e)or a fluorine atom (6j)exhibited more potent antiproliferative effect on SMMC-7721 cells than other compounds.Therefore;the antitumor fluoroquinolones can be designed by replacing the C-3 carboxylic acid group of fluoroquinolones with the thiazolo[3;2-b][1;2;4]triazole moiety.

To discover novel antitumor rhodanine unsaturated ketones, a series of fluoroquinolone (rhodanine α, β-unsaturated ketone) amine derivatives (5a-5r) were designed and synthesized with fluoroquinolone amide scaffold as a carrier. The structures of eighteen title compounds were characterized by elemental analysis, 1H NMR and MS. The in vitro anti-proliferative activity against Hep-3B, Capan-1 and HL60 cells was evaluated by MTT assay. The results showed that the title compounds not only had more significant anti-proliferative activity against three tested cancer cell lines than that of the parent ciprofloxacin 1, but also exhibited the highest activity against Capan-1 cells. The SAR revealed that some compounds carrying aromatic heterocyclic rings or phenyl attached to an electron-withdrawing carboxyl or sulfonamide substituent were comparable to or better than comparison doxorubicin against Capan-1 cells. As such, it suggests that fluoroquinolone (rhodanine α, β-unsaturated ketone) amines are promising leads for the development of novel antitumor fluoroquinolones or rhodanine analogues.

The effects of hypoxia on the expression of Fos was studied in the distal cerebrospinal fluid contacting neurons (CSF-CNs) in the dorsal raphe nucleus (DR) of the rat. The hypoxic models mimic 8000 m high level were established in a high-altitude decompression chamber. Injecting the tracer of CB ( chorela toxin B subunit) into the rat's lateral ventricles, we investigated the distribution of the distal CSF-CNs in the DR. The single and double immunohistochemistry staining with antibodies to Fos and CB were used to observe the expression of Fos in the distal CSF-CNs in the DR. The results showed that a large number of CB-like immunoreactive (-LI) neurons (31.16 ±3.36/per section) were located in the DR. In hypoxic experimental rats, the number of Fos-LI neurons was increased sharply (40.28 ±2.17/per section, P ＜0.05 compared to control rats), and a few CB/Fos-LI neurons (2.00 ±0.39/per section) could be observed in the DR. In control rats, several Fos-LI neurons (5.55 ±0.81/per section) and no CB/Fos-LI neuron could be observed in the DR. These results suggest that some of the distal CSF-CNs in the DR may play roles in transmitting information between brain and cerebrospinal fluid and modulating the function of brain following hypoxic stimulation.

Objective:To explore the behavior and influencing factors of mobile health (m-Health) information searching among patients with cancer, aiming to provide evidence for the provision of medical health information.Methods:A cross-sectional survey was conducted.A total of 535 patients with cancer were recruited from a cancer hospital in Zhejiang Province from September to December 2017.Measurement tools included the demographic information questionnaire, mobile health information search behavior questionnaire, mobile health information search environment questionnaire, cancer needs questionnaires-short form and ehealth literacy scale.SPSS 26.0 was used for descriptive statistical analysis, one-way analysis of variance, Pearson correlation analysis and multiple linear regression analysis.Results:The total score of mobile health information search behavior of cancer patients was (60.84±9.60), and 66.5% of participants reported that they "never" or "occasionally" searched health information via mobile.The total score of information needs was (80.99±27.86), electronic health literacy was (26.54±7.85), mobile health information search environment was (8.00±2.86). m-Health information search behavior was positively correlated with information needs ( r=0.251, P<0.01), ehealth literacy ( r=0.538, P<0.01), and m-Health information search environment ( r=0.267, P<0.01). The stepwise regression analysis revealed that the place of residence, working status, income level, ehealth literacy, mobile health information search environment and information needs were statistically significant associated with the m-Health information searching behavior among cancer patients, which accounted for 39.3% of the total variance ( F=12.151, P<0.01). Compared with patients living in the central cities, those living in the small and medium-sized cities( β=0.092, P=0.031) had higher score in m-Health information behavior.Compared with patients working on normal schedule, those took sick days ( β=0.156, P=0.017) and working fewer hours ( β=0.138, P=0.002) had higher score m-Health information behavior.Compared with patients with monthly income of 1 000-3 000 yuan ( β=-0.194, P=0.002), those with monthly income less than 1 000 yuan had higher score in m-Health information behavior.The ehealth literacy ( β=0.425, P=0.000), mobile health information search environment ( β=0.179, P=0.000) and information needs ( β=0.091, P=0.027) were positive influencing factors of m-Health information search behavior. Conclusion:Patients with cancer did not report high m-Health information search behavior.Place of residence, working status, income level, ehealth literacy, m-Health information search environment and information demand were the influencing factors of m-Health information search behavior among patients with cancer.

The excitability of nociceptive neurons increases in the intact dorsal root ganglion (DRG) after a chronic compression, but the underlying mechanisms are still unclear. The aim of this study was to investigate the ionic mechanisms underlying the hyperexcitability of nociceptive neurons in the compressed ganglion. Chronic compression of DRG (CCD) was produced in adult rats by inserting two rods through the intervertebral foramina to compress the L4 DRG and the ipsilateral L5 DRG. After 5-7 d, DRG somata were dissociated and placed in culture for 12-18 h. In sharp electrode recording model, the lower current threshold and the depolarized membrane potential in the acutely dissociated CCD neurons were detected, indicating that hyperexcitability is intrinsic to the soma. Since voltage-gated K(+) (Kv) channels in the primary sensory neurons are important for the regulation of excitability, we hypothesized that CCD would alter K(+) current properties in the primary sensory neurons. We examined the effects of 4-aminopyridine (4-AP), a specific antagonist of A-type potassium channel, on the excitability of the control DRG neurons. With 4-AP in the external solution, the control DRG neurons depolarized (with discharges in some cells) and their current threshold decreased as the CCD neurons demonstrated, indicating the involvement of decreased A-type potassium current in the hyperexcitability of the injured neurons. Furthermore, the alteration of A-type potassium current in nociceptive neurons in the compressed ganglion was investigated with the whole-cell patch-clamp recording model. CCD significantly decreased A-type potassium current density in nociceptive DRG neurons. These data suggest that a reduction in A-type potassium current contributes, at least in part, to the increase in neuron excitability that may lead to the development of pain and hyperalgesia associated with CCD.
