Objective To compare the applicability of the Beijing Version of the Montreal Cognitive Assessment (MoCA) and the Mini Mental State Examination (MMSE) in screening for cognitive impairment in patients with acute ischemic stroke for 2-3 weeks.Methods MoCA and MMSE were conducted in 201 patients with acute ischemic stroke within 2 to 3 weeks after the onset of stroke.With MoCA<23 and MMSE <26 as the cut off value,we assessed the clinic effect of the MoCA and MMSE and explored the correlation between two instruments.Results The average scores of MoCA and MMSE scale were (20.5±4.3) and (25.4±3.5) points.The prevalence of cognitive impairment evaluated with MoCA and MMSE were 57.2%and 43.3%,respectively.MoCA showed significant correlation with MMSE score (Pearson's correlation coefficient=0.833,P<0.001),and an agreement with Kappa values of 0.532 (P<0.01) in screening for cognitive impairment.Conclusions The prevalence of cognitive impairment assessed with MoCA is higher than that of with MMSE when using MoCA<23 and MMSE<26 as the cut off values.Both instruments show a good agreement for screening cognitive impairment in acute ischemic stroke within 2 to 3 weeks following the disease onset.

Objective:To investigate the effect of bilateral repetitive transcranial magnetic stimulation (rTMS) on the pre-attentive processing of methamphetamine addicts.Methods:Forty methamphetamine addicts were screened and equally divided into the intervention group and the control group by random number table method.The intervention group was treated with bilateral simultaneous stimulation with 10 Hz on the left DLPFC and 1 Hz on the right DLPFC with 7 days of continuous intervention.The same scheme was used to intervene the control group, but with pseudo-stimulation. The changes of amplitude and latency of mismatch negative wave(MMN) before and after intervention were compared. SPSS 24.0 software was used for statistical analysis. Independent sample t-test was used for inter group comparison, and paired sample t-test was used for intra group comparison before and after intervention. Results:Before rTMS, there were no significant differences in MMN(F3, Fz, F4) amplitude (intervention group: (-0.90±0.28)μV, (-0.98±0.19)μV, (-0.96±0.19)μV; control group: (-0.92±0.21)μV, (-0.89±0.20)μV, (-0.94±0.16)μV)and latency(intervention group: (184.16±33.07)ms, (179.20±25.35)ms, (184.95±28.22)ms; control group: (184.91±26.96)ms, (180.99±25.29)ms, (181.55±23.19)ms) between the two groups (all P>0.05). After the intervention, there were significant differences in MMN(Fz, F4) amplitude(intervention group: (-1.38±0.16)μV, (-1.17±0.19)μV; control group: (-0.91±0.17) μV, (-0.99±0.16)μV) between the two groups (both P<0.01), but there were no significant differences in MMN (F3) amplitude(intervention group: (-1.01±0.59)μV; control group: (-0.80±0.50)μV), and in MMN (F3, Fz, F4) latency(intervention group: (177.38±26.45)ms, (172.17±23.87)ms, (179.84±23.60)ms; control group: (182.08±24.95)ms, (177.94±21.30)ms, (179.18±21.62)ms)between the two groups (all P>0.05). There were statistically significant differences in MMN( Fz, F4) amplitude (before-intervention: (-0.98±0.19)μV, (-0.96±0.19)μV; after-intervention: (-1.38±0.16)μV, (-1.17±0.19)μV)before and after intervention in the intervention group (both P<0.05), but there was no significant difference in MMN(F3) amplitude(before-intervention: (-0.90±0.28)μV; after-intervention: (-1.01±0.59)μV)before and after intervention in the intervention group ( P>0.05), and there were statistically significant differences in MMN(F3, Fz, F4) latency (before-intervention: (184.16±33.07)ms, (179.20±25.35)ms, (184.95±28.22)ms; after-intervention: (177.38±26.45)ms, (172.17±23.87)ms, (179.84±23.60)ms)before and after intervention in the intervention group(all P<0.05). After pseudo-stimulation, there were no statistically significant differences in MMN( F3, Fz, F4) amplitude(before-intervention: (-0.92±0.21)μV, (-0.89±0.20)μV, (-0.94±0.16)μV; after-intervention: (-0.80±0.50)μV, (-0.91±0.17)μV, (-0.99±0.16)μV)and latency (before-intervention: (184.91±26.96)ms, (180.99±25.29)ms, (181.55±23.19)ms; after-intervention: (182.08±24.95)ms, (177.94±21.30)ms, (179.18±21.62)ms) before and after intervention in the control group (all P>0.05). Conclusion:After repeated transcranial magnetic stimulation, the pre-attentive processing of the intervention group is improved, which shows that bilateral simultaneous stimulation of the rTMS program is effective.

Objective:To construct an evaluation index system for the core competence of hospital specialist service operation assistants and provide reference for the evaluation of such competence.Methods:From January to March 2022, literature analysis and behavioral event interviews were used to initially establish a core competence evaluation index system of hospital specialist service operation assistants, based on the Donabedian model. Subsequently, the Delphi expert consultation method was applied to conduct correspondence consultation, inviting experts to evaluate the contents and importance of the index system, using analytic hierarchy process to determine the weights of the indexes at all levels.Results:Two rounds of expert consultation were carried out, and the valid recovery rate of the questionnaire was 100%. The familiarity coefficient of the second round of correspondence was 0.87, the basis of judgment coefficient was 0.90, and the authority coefficient was 0.89. The final evaluation index system for core competence of hospital specialist service operation assistant consisted of 3 first-level indexes, 13 second-level indexes and 81 third-level indexes. The weight of the first-level index structure index was 0.266, and the highest weight among the second-level indexes was the operational development ability (0.083), while the highest weight among the third-level indexes of operational development ability was the comprehensive coordination ability (0.193); The weight of the first-level index process index was 0.405, and the corresponding second-level and third-level indexes with the highest weight were department operation practice work (0.157) and reasonable resource allocation (0.303), respectively; The weight of the first-level index result index was 0.329, and the corresponding second-level and third-level indexes with the highest weight were the weight of medical quality and safety (0.103) and drug adverse reaction reporting rate (0.237), respectively.Conclusions:The evaluation index system constructed in this study proves scientific and reasonable in weight assignment, proving a reference for the management of the specialist service operation assistants.

OBJECTIVETo investigate the influence of renal function on the level of β₂-microglobulin (β₂-MG) as prognostic factor in newly diagnosed multiple myeloma (MM) patients, and to analyze the overall survival (OS) in different level of β₂-MG with relatively normal or abnormal renal function in MM patients.
METHODSAccording to the level of β₂-MG, 666 newly diagnosed MM patients were divided into three groups as β₂-MG<3.5, 3.5-<5.5, ≥5.5 mg/L. According to the level of serum creatinine, these patients were divided into two groups:serum creatinine <177 μmol/L as relatively normal group, serum creatinine ≥177 μmol/L as abnormal group.
RESULTSAmong 666 patients, there were 416 male and 250 female, the median age was 58 (25-86) years old. Comparison of OS among β₂-MG<3.5, 3.5-<5.5, ≥5.5 mg/L groups indicated that the median OS of the three groups were 85.75 (95% CI 70.99-100.50), 47.25 (95% CI 40.98-53.53) and 35.05 (95% CI 30.75-39.35) months, respectively (P<0.01). Comparison of OS between serum creatinine <177 and ≥177 mmol/L groups, the median OS of the two groups were 64.67 (95% CI 56.57-72.77) and 32.74 (95% CI 27.74-37.73) months, respectively (P<0.01). In β₂-MG≥5.5 mg/L, the median OS of relatively normal and abnormal groups were 37.25 (95% CI 31.45-43.06) and 32.55 (95% CI 26.26-38.83) months, respectively (P=0.142).
CONCLUSIONHigh level of β₂-MG and renal function correlated with shorter survival of MM patients. Higher level of β₂-MG with abnormal renal function can't change the prognostic value of β₂-microglobulin on MM.
