RESUMO
Objective: To explore the moderating mechanism of mindfulness on perceived stress and job burnout of medical staff. Methods: From November 2020 to March 2022, 1626 medical staff were investigated by questionnaires. Chinese Version Perceived Stress Scale (CPSS), Maslach Burnout Inventory-Human Service Survey (MBI-HSS) and Mindful Attention Awareness Scale (MAAS) were used to evaluate the perceived stress, three dimensions of job burnout[depersonalization (DP), emotional exhaustion (EE), personal accomplishment (PA) ], and mindfulness level of medical staff. The Spearman rank correlation analysis was used to analyze the correlation between mindfulness and perceived stress, job burnout of medical staff. And the SPSS PROCESS macro program was used to test the moderating effect of mindfulness on perceived stress and job burnout. Results: Among the 1626 medical staff, 57.38% had perceived stress with health risk (933/1626), and 63.84% (1038/1626) had job burnout, among them, with 618 (38.01%), 274 (16.85%), and 146 (8.98%) experiencing mild, moderate and severe job burnout, respectively. The scores of mindfulness among medical staff were significantly correlated with perceived stress and various dimensions of job burnout (EE, DP and PA) (r(s)=-0.155, -0.351, -0.315, 0.307, P<0.001). Mindfulness had a moderating effect between perceived stress and job burnout, which was achieved through three moderating pathways: perceived stress-mindfulness-EE, perceived stress-mindfulness-DP and perceived stress-mindfulness-PA (ΔR(2)=0.073, 0.06, 0.006, P<0.001) . Conclusion: Medical staff have a high level of job burnout, mindfulness plays a moderating role between perceived stress and job burnout. Specific measures can be taken to improve the level of mindfulness in medical staff, so as to prevent and alleviate job burnout of medical staff.

Objective: To investigate the efficacy and tolerability of Polatuzumab vedotin+rituximab±bendamustine (Pola-(B)R) in relapse/refractory diffuse large B cell lymphoma (R/R DLBCL) patients. Methods: The clinical data of 21 patients enrolled in Chinese Pola compassionate use program (CUP) in 4 centers from November 2019 to August 2020 were collected. There were 15 males and 6 females, and the median age was 56 years (ranged 25-76 years). Of the patients, 10 cases received Pola-BR regimen and the other 11 received Pola-R. Their clinical features, regimens, efficacy, and adverse events (AEs) were retrospectively analyzed. Results: Twenty-one patients with at least one efficacy evaluation were included. At data analysis cut-off point (12 Aug. 2020), the best overall response (BOR) rate was 81.0% (17/21) and the complete response (CR) rate was 19.0% (4/21). Kaplan-Meier survival estimation was performed, at a median follow-up of 54 days, three patients (14.3%) had disease progressed, and 18 patients (85.7%) were censored; the median progression-free survival (mPFS) was estimated to be 148 days. The incidence of adverse effects (AEs) of any grade was higher in Pola-BR group than Pola-R group (80.0% vs 63.6%). However, the incidence of grade 3-4 AEs were close in the two groups (30.0% vs 29.3%). The most common hematological toxicities were thrombocytopenia (28.6%, 6/21), neutropenia (28.6%, 6/21) and anemia (14.3%, 3/21), respectively. One patient with pneumonia and 1 patient with hemophagocytic syndrome recovered after symptomatic treatment. No peripheral neuropathy of grade≥2 was observed. Conclusions: The preliminary data suggested that, for heavily treated Chinese R/R DLBCL, the Pola-(B)R regimen still achieves promising efficacy and tolerable safety.

Monomethoxypolyethylene glycol-chitosan (mPEG-CS) nanoparticles were used as interfering RNA carriers to transfect human prostate cancer PC-3M cells to evaluate the effects of livin and survivin gene silencing on the proliferation and apoptosis. mPEG-CS nanoparticles with sizes of approximately 60 nm were first synthesized by ionic crosslinking. Through electrostatic adsorption, mPEG-CS-livin short hairpin RNA (shRNA), mPEG-CS-survivin shRNA, and mPEG-CS-(livin shRNA + survivin shRNA) nanoparticles were then prepared to transfect PC-3M cells. The mRNA and protein expression levels of livin and survivin were measured by reverse transcription-PCR and western blotting, respectively. The inhibitory effects of down-regulated livin and survivin gene expression on the cell proliferation were evaluated by MTT assay. Cell apoptosis was assessed visually using Hoechst staining. Livin and survivin expression levels in all shRNA interference groups were effectively down-regulated at both the mRNA and protein levels. Dual silencing of livin and survivin genes markedly inhibited cell proliferation and facilitated apoptosis, with better outcomes than those of individual shRNA treatments. mPEG-CS nanoparticle-mediated dual shRNA interference of livin and survivin genes significantly reduced the expression levels in PC-3M cells, inhibited proliferation, and promoted apoptosis. As these effects were superior to single interference, this method may have synergistic effects.

5-Fluorouracil (5-FU) is widely used in chemotherapy for treatment of colorectal cancer. Leucine-rich repeat-containing G protein-coupled receptor (LGR) is known to participate in the occurrence and development of breast cancer by regulating the rebirth of tumor vessels. This study aimed to explore the proliferation and apoptosis of HCT116 colorectal cancer cells treated with 5-FU and related molecular mechanisms. 5-FU (20 µg/mL) was used to treat cultured HCT116 cells. An MTT test, flow cytometry, and colony formation assays were used to examine the proliferation and apoptosis of HCT116 cells. Western blotting was applied to detect the expression of the LGR4 protein in HCT116 cells. Small interference RNA or over-expression techniques were used to manipulate LGR4 expression in HCT116 cells and describe the proliferation and apoptosis of HCT116 treated with 5-FU. A dosage of 20 µg/mL 5-FU resulted in a significant decrease in the proliferation and apoptosis of HCT116 cells and significantly decreased expression levels of LGR4. The specific gene silence or over-expression of LGR4 in HCT116 cells increased and decreased the levels of apoptosis in HCT116, respectively. 5-FU induces apoptosis of colorectal cancer cells and inhibits proliferation by suppressing LGR4 proteins.

In Guangxi Province of southwest China, diseases caused by Tospoviruses (family Bunyaviridae) pose a serious threat to tobacco (Nicotiana tobacum) production. During surveys conducted annually at Xinrong Village in Jingxi County from 2008 to 2010, more than 130 ha of fields were found to have 10 to 50% of plants exhibiting symptoms similar to spotted wilt caused by Tomato spotted wilt virus (TSWV). During this period, disease symptoms at similar prevalence and incidence were also found at Fushan, Debao County in most of the cultivars produced in these areas, including Yunyan 85, 87, 92, 97, and K326. Symptoms on tobacco varied but commonly included dwarfing, midrib browning, distorted apical buds, and concentric ringspots that coalesced to form large areas of dead leaf tissue. Mechanical inoculation from diseased tobacco leaves with concentric ringspots back to tobacco cv. Yunyan 85 or 87, resulted in 12 of 16 plants with symptoms similar to those observed in the field. No symptoms on plants developed following inoculation with buffer only. Symptoms found in the field resembled those caused by TSWV. However, testing using TSWV-specific antiserum was shown to be negative by double-antibody sandwich-ELISA (Agdia, Elkhart, IN). Total RNA was extracted from 27 diseased tobacco plants collected from different regions in Guangxi using Trizol reagent (Invitrogen, Carlsbad, CA) according to the manufacturer's instructions. RNA extracts were amplified by reverse transcription (RT)-PCR using the degenerate primers T2740 (ATGGGDATNTTTGATTTCATG) and T3920c (TCATGCTCATSAGRTAAATYTCTCT) designed to target the partial RNA-dependent RNA polymerase (RdRp) sequence of members in the genus Tospovirus (3). Amplification was performed at 42°C for 60 min, followed by 35 cycles of PCR (30 s denaturation at 94°C, 45 s annealing at 55°C, and 30 s extension at 72°C) and a 7-min final extension at 72°C. A PCR product of approximately 1.2 kb was amplified from 21 diseased plants. RT-PCR amplicons were cloned into the pUC19-T Simple Vector (TaKaRa, Dalian, China) and sequenced in both directions. Sequences were assembled and analyzed by DNAStar 5.01 (DNASTAR, Madison, WI). Sequences of representative isolates were deposited in GenBank (Accession Nos. JN020022 to JN020027). The 1.2-kb partial RdRp sequences of these isolates were shown to have 94.4 to 95.3% nucleotide identity and 96.5 to 97.5% amino acids identity to Tomato zonate spot virus (TZSV) (GenBank Accession No. NC_010491) (1). Among these TZSV isolates from Guangxi, the partial RdRp sequences have 98.0 to 99.4% nucleotide identity and 98.8 to 100% amino acids identity with each other. The presence of TZSV was further confirmed in diseased tobacco plants by indirect ELISA using antiserum of TZSV (provided by Prof. Zhongkai Zhang, Agricultural Academy of Yunnan, China). TZSV has been characterized as a novel tospovirus on various hosts including tobacco in Yunnan province (1,2). To our knowledge, this is the first report of TZSV-associated disease on tobacco in Guangxi Province, southwest China. Further work is necessary to study the epidemiology and management of the disease. References: (1) J. Dong et al. Arch. Virol. 153:855, 2008. (2) J. Dong et al. J. Insect Sci. 10:166, 2010. (3) Y.

RESUMO
A large quantity of uniform ZnO nanoneedles has been synthesized by thermal evaporation method. Both single and double tip ZnO nanoneedles were found coexistence in the as-synthesized products. The single tip nanoneedles are major products in the synthesis and a few double tip nanoneedles were also observed. The polarity of the nanoneedles was characterized by convergent beam electron diffraction (CBED) and the simulation results reveal that the polarity of the ZnO (0001) surface directs the preferential growth of the nanoneedles. It is also found that most of the double tip nanoneedles are originated from the joint growth of two single tip nanoneedles with a kink in the middle and smooth ones might be generated from forming thin layer of cubic structures in the double nanoneedle tips. A large quantity of ZnO nanorod building blocks without tips was also achieved by fast cooling. The formation of the nanoneedles and nanorods can be attributed to different cooling speeds in our experiments. The sharp single nanoneedle tip can be potentially used as scanning probe microscope or field-emission tips.
RESUMO
A fungus-derived compound (OSI-2040) which induces fetal globin expression in the absence of erythroid cell differentiation was identified in a high-throughput drug discovery program. We utilized this compound to isolate gamma-globin regulatory genes that are differentially expressed in OSI-2040-induced and uninduced cells in the human erythroleukemia cell line K562. Representational difference analysis (RDA) of cDNA revealed several genes that were significantly up- or down-regulated in OSI-2040-induced cells. One gene whose expression was markedly enhanced was the gene for the helix-loop-helix (HLH) transcription factor Id2. Southern analysis of RDA amplicons demonstrated progressive enrichment of Id2 with each successive subtraction of uninduced cDNA from induced cDNA. Northern analysis of OSI-2040-induced K562 cells confirmed that Id2 expression was directly up-regulated coordinately with gamma-globin. Analysis of other inducers of fetal globin demonstrated up-regulation of Id2 with sodium butyrate but not with hemin. Retrovirus-mediated overexpression of Id2 in K562 cells reproduced the enhancement of endogenous globin expression observed with OSI-2040 induction. Functional assays demonstrated that an E-box element in hypersensitivity site 2 is required for Id2-dependent enhancement of gamma-promoter activity. Protein binding studies suggest that alterations in E-box site occupancy by basic HLH proteins may influence this activity, thus expanding the potential role of these factors in globin gene regulation.

Rutile-type Co-doped SnO(2) nano-crystal powders are prepared by the wet chemical method. The magnetic moment is found to decrease with increasing Co content. There is hysteresis between field cooled (FC) and zero field cooled (ZFC) magnetization when the temperature is below 70 K. These magnetic behaviours represent antiferromagnetic interaction between Co ions. By measuring the magnetization as a function of temperature, the magnetic interaction between Co ions is evaluated qualitatively using the Curie-Weiss law. The value of the effective exchange integral J(1)/k(B) is about -62 K, indicating a very strong antiferromagnetic superexchange interaction between Co ions.

Previous work from our laboratory has provided evidence for the presence of a tissue renin-angiotensin system in the rat epididymis. In the current investigation, the regional localization of angiotensin II receptors, type I (AT1) and type II (AT2) was studied immunocytochemically using specific anti-peptide antibodies against the second extracellular loops of AT1 and AT2 receptors, and pharmacologically using specific receptor antagonists in conjunction with the short-circuit current technique. The immunocytochemical results showed that AT1 and AT2 immunoreactivities were predominantly localized in the basal region of the epididymal epithelium. Electrophysiological studies using the short-circuit current technique demonstrated a stimulatory effect of basolaterally applied angiotensin II on the epididymal electrogenic ion transport. This effect was inhibitable by the addition of AT1 antagonist, losartan but not by AT2 antagonist, PD123177, indicating a functional role of AT1 in epididymal electrolyte transport. The present finding suggests that angiotensin II receptors may play an important role in the regulation of epididymal function.

The present study investigated the role of pituitary adenylate cyclase-activating polypeptide (PACAP) in the regulation of electrogenic anion secretion by the rat cauda epididymal epithelium. PACAP38, which has been shown to affect secretory function in various exocrine and endocrine tissues, gave rise to a concentration-dependent increase in the short-circuit current (Isc). The PACAP38 effect was restricted to the apical aspect of the epididymal cells. The Isc response to PACAP38 was abolished in Cl-(-)free solution and completely inhibited by the Cl- channel blocker, diphenylamine-dicarboxylic acid. The Isc response to PACAP38 was also suppressed by pretreatment of the cells with the adenylate cyclase inhibitor, MDL12330A. The localization of PACAP38 was further investigated using an immunohistochemical technique. PACAP38 immunoreactivity was observed in the cauda epididymal tubules as well as in the cultured epithelium, indicating its epithelial origin. The present results suggest that Cl- secretion in the epididymis may be regulated by PACAP38, which could be locally synthesized and released by the epithelial cells, in a paracrine or autocrine fashion.

Release of Ca2+ from intracellular Ca2+ stores (Ca2+ mobilization) and capacitative Ca2+ entry have been shown to be inducible in neuroepithelial cells of the early embryonic chick retina. Both types of Ca2+ responses decline parallel with retinal progenitor cell proliferation. To investigate their potential role in the regulation of neuroepithelial cell proliferation, we studied the effects of 2,5-di-tert-butylhydroquinone (DBHQ), an inhibitor of the Ca2+ pump of intracellular Ca2+ stores, and of SK&F 96365, an inhibitor of capacitative Ca2+ entry, on DNA synthesis in retinal organ cultures from embryonic day 3 (E3) chicks and in dissociated cultures from E7 and E9 chick retinae. We demonstrate that both antagonists inhibit [3H]-thymidine incorporation in a dose-dependent manner without affecting cell viability or morphology. The inhibition of [3H]-thymidine incorporation by SK&F 96365 occurred in the same concentration range (IC50: approximately 4 microM) as the blockade of capacitative Ca2+ entry in the E3 retinal organ culture. At a concentration of 5 microM SK&F 96365. DNA synthesis was reduced by 71, 40 and 32% in the E3, E7 and E9 cultures, respectively. Application of DBHQ at concentrations which led to depletion of intracellular Ca2+ stores also inhibited [3H]-thymidine incorporation with IC50 values of 20-30 microM in the different cultures. Our results suggest the involvement of Ca2+ mobilization and capacitative Ca2+ entry in the regulation of DNA synthesis in the developing neural retina.

The activation of P2 purinoceptors induces Ca2+ mobilization in the early embryonic chick neural retina. This purinergic Ca2+ response declines parallel with the decrease in mitotic activity during retinal development. To investigate the role of P2 purinoceptors in the regulation of retinal cell proliferation, we studied the effects of the P2 purinoceptor antagonists suramin and pyridoxalphosphate-6-azophenyl-2',4'-disulphonic acid (PPADS), and of the agonist ATP on DNA synthesis in retinal organ cultures from embryonic day 3 (E3) chick. Suramin inhibited [3H]-thymidine incorporation in a dose-dependent manner (IC50: approximately 70 microM). PPADS also reduced [3H]-thymidine incorporation with maximum inhibition of 46% at 100 microM. Exogenous ATP enhanced [3H]-thymidine incorporation in a dose-dependent manner to maximally 200% of control (EC50: approximately 70 microM). In dissociated retinal cultures from E7 chick, both antagonists showed similar inhibitory effects on [3H]-thymidine incorporation without affecting cell viability. In line with these observations, the presence of extracellular ATP was demonstrated both in vitro and in vivo. In the medium of E3 retinal organ cultures, the concentration of ATP increased 25-fold within 1 h of incubation and this concentration was kept for at least 24 h. In the chick amniotic fluid, the ATP concentration was nearly 3 microM at E3 and declined to 0.15 microM at E7. The results indicate that P2 purinoceptors activated by autocrine or paracrine release of ATP are involved in the regulation of DNA synthesis in the neural retina at early embryonic stages.

RESUMO
Capacitative Ca2+ entry occurs in the neural retina of chick embryo during neurogenesis. We studied the effects of blockers of capacitative Ca2+ entry (SK&F 96365, Zn2+, Ni2+), genistein, a tyrosine kinase inhibitor and vanadate, a protein-phosphotyrosine phosphatase inhibitor in the embryonic chick retina with fura-2 fluorescence measurements. After incubation of the retina in a Ca2+-free solution with or without an inhibitor of Ca2+ pumps of intracellular Ca2+ stores, re-introduction of extracellular Ca2+ caused capacitative Ca2+ entry which was inhibited by SK&F 96365 (10 microM), Zn2+ (1 mM), Ni2+ (5 mM) and genistein (100 microM). On the contrary, vanadate (1 mM) enhanced the Ca2+ entry. These results suggested that tyrosine phosphorylation was involved in the activation of capacitative Ca2+ entry.

UNLABELLED: The character of "Spleen Deficiency" (SD) Syndrome was evaluated by determination of the blood levels of various gastroenteropancreatic hormones and thyroid hormone. Patients of SD group were diagnosed clinically by Syndrome Differentiation, and those of the normal group were volunteer blood donors. RIA was used to determine all the hormones except T3RUR. RESULTS: TT3, FT3 of the SD group were very significantly lower than that of normal group (P less than 0.001). The levels of rT3 in SD group were significantly higher than normal control (P less than 0.05). For TT4, T3RUR and FT4, there were no significant differences between the two groups. Among the gastroenteropancreatic hormones, gastrin in the SD group was significantly lower than that of the normal group (P less than 0.01), motilin was very significantly higher (P less than 0.002). The value of pp was similar in the two groups, under physiological conditions, however, in adults the hormone tended to increase with age. Since the average age of patients in the SD group was 54.9, and that of the normal group was 38.5, remarkably lower values were seen in the SD group. Other hormones such as VIP, SST, glucagon and insulin were of no significant difference between the two groups. The result showed that thyroid hormone and some of gastroenteric hormones in the blood of patients with SD after major operations were quite different from normal, and was common to patients with general SD Syndrome, with low T3 syndrome.(ABSTRACT TRUNCATED AT 250 WORDS)

Density functional theory calculations of NdAlO3/SrTiO3 heterostructure show that two-dimensional electron gas (2-DEG) is produced at the interface with a built-in potential of ~0.3 eV per unit cell. The effects of surface defects on the phase stability and electric field of 2-DEG have been investigated. It is found that oxygen vacancy is easily to form on the NdAlO3(001) surface, with a low threshold displacement energy and a low formation energy. This point defect results in surface reconstruction and the formation of a zigzag -Al-O-Al- chain, which quenches the built-in potential and enhances the carrier density significantly. These results will provide fundamental insights into understanding how surface defects influence the electronic behavior of 2-DEG and tuning their electronic properties through surface modification.

This study compared the clinical results of surgical treatment of high complex anal fistula with a conventional seton and a new type of seton consisting of an elastic sheath and alloy core tube for irrigation of the wound track. A total of 438 patients were included in the study; 215 were treated with a conventional seton and 223 with the new-type seton. In patients treated with the new-type seton, the wound track was irrigated daily with 100 ml physiological saline, 100 ml hypertonic saline and 0.5 g metronidazole gel from the second postoperative day until seton removal. The new-type seton was associated with significant reductions in recurrence rate, length of stay and healing time compared with the conventional seton, but there were no significant differences in operation time or postoperative incontinence rates. It is concluded that the new-type seton with irrigating tube can improve the treatment of high complex anal fistula.
