Objective:To explore the effect of healthcare failure mode and effect analysis (HFMEA) in reducing the incidence of nursing interruption with negative outcome in operating room, so as to maximize the smooth progress of the surgical process.Methods:This was a quasi experimental study. The gastrointestinal surgery room of Shandong Provincial Hospital Affiliated to Shandong First Medical University was selected for the study. According to the surgical sequence, 38 surgeries performed in the gastrointestinal surgery suite from August 15-30, 2021 were set as the control group, and the conventional healthcare cooperation model process was implemented; 42 surgeries performed from September 15-30, 2021 were set as the intervention group, and the operating room under the HFMEA model was implemented negative outcome care disruption event management process.A video tracking method combined with a surgical care disruption event register was used to investigate the occurrence of negative outcome care disruption events in the operating room, comparing the number, duration, source of disruption events and the incidence of near miss events in the operating room between the control group and the intervention group.Results:In the control group, there were 38 observed surgeries, 190 negative outcome care interruptions, negative outcome interruptions of (5.26 ± 1.02) min duration, and no near misses; in the intervention group, there were 42 observed surgeries, 84 negative outcome care interruptions, negative outcome interruptions of (2.06 ± 0.08) min duration, and no near misses. There were statistically significant differences in the number, duration of negative outcome care interruptions between the intervention group and the control group ( χ2 = - 18.71, t = - 20.28; all P<0.01). There was statistically significant difference in the source of negative outcome care interruptions between the intervention group and the control group ( χ2 = - 12.71, P<0.01). Conclusions:HFMEA model can effectively reduce the number of negative nursing interruptions in the operating room, shorten the duration of interruptions, and minimize potential safety hazards caused by nursing interruptions, which is conducive to ensuring the safety of patients.

Objective:To compare the efficacy and safety between WangShiBaoChiWan and mosapride in the treatment of functional dyspepsia (FD).Methods:From September 2019 to September 2020, patients with postprandial fullness and early satiation who met the Rome Ⅳ criteria for FD diagnosis were enrolled from 15 hospitals, including the First Affiliated Hospital of Naval Medical University (Shanghai Changhai Hospital), Beijing Traditional Chinese Medicine Hospital Affiliated to Capital Medical College. The subjects were randomly divided into WangShiBaoChiWan (experimental) group and mosapride (control) group in the ratio of 1∶1. The treatment regimens were WangShiBaoChiWan+ mosapride simulator, WangShiBaoChiWan simulator+ mosapride, respectively with a treatment period of 2 weeks. The primary efficacy outcome was the improvement rates of main symptoms before and after treatment, the secondary efficacy primary efficacy outcome was the total clinical effective rate and the change of the single symptom score. And the safety indicator included adverse events. Independent sample t-test, paired t-test and chi-square test were used for statistical analysis. Results:A total of 251 FD patients were enrolled in the full analysis set, including 124 in the experimental group and 127 in the control group; 241 FD patients were in the per-protocol analysis set, including 117 in the experimental group and 124 in the control group. The analysis of per-protocol analysis set showed that the improvement rates of the main symptoms of the experimental group and the control group were (66±29)% and (60±30)%, respectively, and the difference was not statistically significant ( P>0.05). The improvement rate of the main symptoms of the experimental group reached 117% of that of the control group, which exceeded the expected non-inferiority standard of 80%. The total clinical effective rates of the experimental group and the control group were 76.07% (89/117) and 75.81% (94/124), respectively, and the difference was not statistically significant ( P>0.05). The results of full analysis set showed that the incidence of adverse events of the experimental group and the control group was 1.62% (2/124) and 1.57% (2/127), respectively, and the difference was not statistically significant ( P>0.05). There were no serious adverse events in the two groups. Conclusion:The improvement rate of the main symptoms of WangShiBaoChiWan is not inferior to that of mosapride in the treatment of FD, and it has good safety.

As the reinspection work affects the final conclusion of sampling inspection, inappropriate overturn during the reinspection has already impaired the impartiality and authority of the supervisory inspection work. By the statistics of survey materials, this article analyzes the reasons for requesting reinspection and making overturns,and proposes a scheme for eliminating the interference factors such as the understanding divergences and the defects of standards,the inspection capacity and the issues of sampled devices, etc. To enhance the authoritative of reinspection, this article also proposes principals of evasion, precedence, arbitration and assessment, and the improvement of the reinspection workflow in order to make the reinspection work more appropriate, more efficient and more impartial.

The process of exercise regulating bone metabolism is complicated, which involves a number of signaling pathways. A large number of studies in vitro have indicated that mechanical stress regulates bone metabolism by Wnt, bone morphogenetic protein (BMP), and osteoprotegerin (OPG)/receptor activator of NF-κB ligand (RANKL)/receptor activator of NF-κB (RANK) signaling pathways. Both the in-tensity and frequency of mechanical stress have varing impact on bone tissue and cells. Plenty of studies in vivo also have shown that exer-cise regulates bone metabolism by key factors in bone metabolism signaling pathways. This paper reviewed the effects of exercise on bone metabolism pathways and their mechanisms.

Aim To investigate the function of fenofi-brate on PAN ( puromycin aminonucleoside )-induced podocyte injury. Methods SD female rats of 18-week-old were randomly assigned into 3 groups ( n =6 ) . Mice in PAN group and fenofibrate treated group received a single intravenous injection of PAN ( 65 mg ·kg-1 ) , while those in control group received equal volume of saline. Mice in fenofibrate treated group re-ceived 40 mg · kg-1 · d-1 of fenofibrate ( intragastric administration ) on day 1 after PAN injection , while those in PAN group and control group received equal volume of vehicle. 24 hours urine samples from all group were collected on day 0(1 day before PAN injec-tion), day 6, day 10. The 24 hours urine protein was detected by Bradford assay. All the rats were sacrificed 10 days after the induction of podocyte injury, and glo-merulus sample were collected. The expression of podocyte injury marker and transcription level in apop-tosis, podocyte cytoskeleton protein, slit diaphragm protein were evaluated by Western blot and real-time PCR. Results Compared with the control group, 10 days after injection of PAN, 24 hours urine protein was obviously increased, and the expression and transcrip-tion level of podocyte injury marker desmin, apoptosis, podocyte cytoskeleton protein, slit diaphragm protein were upregulated greatly, however, those were signifi-cantly lower in fenofibrate treated group as compared with those in PAN group. Conclusions PPAR-α ago-nist fenofibrate can ameliorate PAN-induced glomerulus podocyte injury, and the mechanism involved may be associated with inhibition of the mitochondria apopto-sis, TGF-β/Smad pathway and p38 pathway.
