Objective To investigate the clinical efficacy of Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) battery for patients at the early stage of traumatic brain injury (TBI). Methods 72 patients with TBI hospitalized from January, 2013 to October, 2014 and 30 healthy controls matched gender, age and educational background were assessed with the Chinese version of LOTCA battery and Mini-Mental State Examination (MMSE) respectively. Results The score of MMSE and LOTCA were correlated (r=0.56, P<0.01). Compared with the controls, the scores of all the subtests of LOTCA decreased (P<0.01) in the patients, especially the orientation, visuomo-tor organization and thinking operation;with the more incidence of medium and serious dysfunction of all the subtests of LOTCA except perception (P<0.01), in which thinking operation was the most and attention was the least. The area under the receiver operating curve (ROC) was (0.84±0.04) in LOTCA, less than that of (0.91±0.03) in MMSE (P<0.05). Conclusion Cognition is widely impaired in patients after TBI, most involved thinking operation. LOTCA is less effective to identify cognitive dysfunction than MMSE, and can be used as an al-ternation or a supplement.

Delirium and cognitive impairment are common in the intensive care units (ICU). The Confusion Assessment Method Inten-sive Care Unit (CAM-ICU), Intensive Care Delirium Screening Checklist (ICDSC), Cognitive Test for Delirium (CTD), Nursing Delirium Scale (Nu-DESC) and Delirium Rating Scale (DRS) are recommended to assess delirium. CAM-ICU and ICDSC are the best in the reliabili-ty, validity, sensitivity and specification. Mini-Mental State Examination (MMSE), Abbreviated Mental Status Examination (AMSE), the Johns Hopkins Adapted Cognitive Exam are used commonly for cognitive impairment, and Johns Hopkins Adapted Cognitive Exam is one of the suitable scales for ICU as it is simple, comprehensive, and with higher reliability and validity.

Objective To evaluate the Montreal cognitive assessment (MoCA) for detecting the mild cognitive impairment (MCI) in brain trauma patients with normal mini-mental state examination (MMSE) scores.Methods Fifty brain trauma patients with normal MMSE scores hospitalized from January 2013 to June 2014 were subjected to the MoCA test.The patients were classified as cognitive impairment group scored less than 26 on the MoCA and cognitive normal group scored 26 or above on the MoCA.Differences in MMSE and MoCA scores of the two groups were compared.Receiver operative characteristic (ROC) curve was used to determine the optimal cut-off scores in screening for MCI.Results Overall MMSE and MoCA scores were (27.84 ± 0.89) points and (23.24 ± 2.90) points.There was a positive correlation between MoCA and MMSE total scores (r =0.355 2,P ＜ 0.05).MCI was found in 79％ of the brain trauma patients using the MoCA.MMSE total score and subscores were all similar between the two groups.MoCA total score and subscores of attention,language,abstraction and delayed recall were much higher in cognitive normal group than in cognitive impairment group (P ＜0.05),but there were no significant differences in visuospatial,naming and oritention domains.Area under the ROC curve for MoCA(0.871 ± 0.038) was larger compared with MMSE (0.796 ± 0.054) (Z =3.592,P ＜ 0.05).The optimal cut-off scores of MoCA and MMSE for the identification of MCI were 25.5 and 28.5 respectively.Conclusions MoCA and MMSE total scores are positively correlated.MoCA is a better detector for the identification of MCI in brain trauma patients than the MMSE.

Objective To summarize and analyze the epidemiological and clinical characteristics of COVID-19 Omicron variant cases in makeshift hospital, and the influence of age, sex and vaccination status on the disease duration, so as to provide reference for the prevention and control of the COVID-19 epidemic. Methods The epidemiological and clinical characteristics of COVID-19 cases admitted to makeshift hospital of National Convention and Exhibition Center (Shanghai) from April 9 to May 31, 2022 were retrospectively described and analyzed, and further cohort analysis was conducted to determine the influence of age, sex and vaccination status on the disease duration of COVID-19 cases in the author's branch hospital. Results Among the 174 466 COVID-19 cases in makeshift hospital, most of them were male, accounting for 59.38%. The infected cases were mainly young and middle-aged people aged 18-59 years old, accounting for 83.50%, followed by 12.30% of the elderly group over 60 years old; the average hospital stay was 7.40 days; the proportion of patients with fever was less than 27.79%; 15.37% (26 817/174 466) of the patients complicated with underlying diseases, and the top three were hypertension, diabetes and coronary heart disease. The proportion of people who received COVID-19 vaccine accounted for 79.56% (13 799/17 956), of which the highest proportion of three doses was 44.09%. The disease duration of 17 956 COVID-19 cases in the author's branch of makeshift hospital was 10.18 (7.34, 13.05) days. The disease duration in the elderly group was the longest with 11.34 (8.35, 14.37) days, followed by 11.17 (9.07, 14.33) days in the preschool group, 10.37 (8.14, 13.34)· days in the middle-aged group, 10.07 (7.37, 12.37) days in the school-age group, and 9.34 (7.05, 12.16) days in the young group. There was significant difference in the overall distribution of disease duration among the five groups (H=550.479 P<0.01). The disease duration in each age group basically showed a V-shaped distribution. The disease duration was 10.27 (7.34, 12.57) days in males and 10.10 (7.25, 13.09) days in females, and there was no significant difference (Z=-1.505 P>0.05). The disease duration of vaccinated patients was 10.24 (7.35, 13.05) days, and that of unvaccinated patients was 9.47 (7.09, 12.47) days. There was significant difference between the two groups (Z=-4.338 P<0.01). Conclusions COVID-19 Omicron variant cases have a high proportion of males, mainly young and middle-aged, and the proportion of fever patients is less than 30%. The disease duration is significantly lower than that of the original strain in Wuhan, and shows "V" distribution with each age group. Sex had no effect on the disease duration. COVID-19 vaccination did not have a clinical effect on the disease duration.

With the advent of Twenty-First century, more and more genome-wide association studies (GWAS) showed that idiosyncratic adverse drug reactions (ADRs) were closely related with human leukocyte antigen (HLA) alleles, such as the associations of abacavir-HLA-B*5701, allopurinol-HLA-B*5801, and carbamazepine-HLA-B*1502, etc. To explore the mechanisms of these idiosyncratic drug reactions, hapten hypothesis, danger signal hypothesis, pharmacological interaction (P-I) concept and autoimmune mechanism are proposed. In this paper, recent GWAS studies on the HLA-mediated adverse drug reactions and underlying mechanism are reviewed in detail.

To explore the influence of matrix materials in complicate ingredients on traditional Chinese medicine and investigate the excipients selection model based on balanced release characteristics of multicomponents, the influence of HPMC (K4M, K15M, K100M) and Carbomer (934P, 971P, 974P) was illustrated by testing in vitro release of ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in Panax notoginseng saponins (model drug, PNS). According to in vitro release results of PNS matrix tablets in water and artificial intestinal juice, the release curves were analyzed with Peppas equation and simulating factor (f). Significant differences in k value and n value among ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 existed in various formulations. The release behaviors from various excipients could be described with Non-Fickian transport or super Case II transport pattern. The f2 values for ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in 971P matrix tablet containing 30% Carbomer 971P were 74.91, 53.45, 57.89 in water and 79.35, 55.51, 51.89 in artificial intestinal juice, respectively. The release profiles fit for the regulation of FDA. The result revealed that the balanced release rates of Rg1, Rb1 and R1 in 971P matrix tablet were obtained.
