ABSTRACT
Objective:To explore the impact of treatment duration with human urinary kallidinogenase (HUK) on the efficacy and safety of acute ischemic stroke (AIS).Methods:In this subgroup analysis of RESK study, a total of 990 AIS patients recruited from 65 centers in China between August 2015 and June 2020 were included and divided into short medication group (HUK for 8 days, n=185) or long medication group (HUK for 15 days or 21 days, n=805). The proportions of patients with modified Rankin Scale (mRS) score of 0, 0-1, 0-2 at 90 days, National Institutes of Health Stroke Scale (NIHSS) score change from baseline to 22 days, the proportions of patients with Barthel index (BI)≥95 at 90 days, and the incidences of adverse events were analyzed. Comparisons between groups were conducted using chi-square test, single factor and multivariate Logistic regression analysis, etc. Results:Multivariate regression analysis showed that the proportions of patients with 90-day mRS score of 0-2 [74.1% (137/185) vs 75.0% (604/805); OR=1.047, 95% CI 0.676-1.620, P=0.838] and 22-day NIHSS score change from baseline (4.60±2.00 vs 4.26±2.80; OR=-0.390, 95% CI -1.125-0.344, P=0.297) showed no statistically significant difference between the short medication and long medication groups; the proportions of patients with 90-day mRS score of 0-1 [48.1% (89/185) vs 59.1% (476/805); OR=0.674, 95%CI 0.463-0.983, P=0.041] and 90-day BI≥95 [43.6% (79/181) vs 55.1% (442/802); OR=0.614, 95%CI 0.420-0.897, P=0.012] were significantly lower in the short medication group than in the long medication group. There was no statistically significant difference in the incidences of adverse events between these 2 groups. Conclusions:In AIS patients, consecutive 8-day dosing of HUK improved immediate (22-day NIHSS score) and long-term outcome (90-day mRS score 0-2) and was safely tolerated. When applicable, extended duration of HUK could improve long-term disability-free rate (90-day mRS score 0-1) and quality of life (90-day BI) without increasing the risk of adverse events.

ABSTRACT
ObjectiveTo explore the effects of body weight and waist circumference on static and dynamic balance function in overweight and obese adults. MethodsParticipants (n=103) were selected by cluster random sampling from the Hypoglycemic Weight Loss Clinic of the Endocrinology Department of the Third Affiliated Hospital of Sun Yat-sen University. All participants were assessed for basic data collection, biochemical test, body weight, waist circumference and height measurement, static balance function assessed by balance error scoring system (BESS) and dynamic balance function assessed by functional reach test (FRT). The BESS score and FRT distance of all participants were compared among groups according to different BMI grades and WC grades. Multivariate linear regression was used to analyze the influencing factors of participants' dynamic and static balance functions. Results① With the increase of BMI grading, the BESS score showed an upward trend, and the difference between groups was statistically significant (P = 0.004). The BESS score of normal WC patients was lower than that of central obesity patients (P < 0.001), which indicated that compared with normal BMI, overweight and obese people had poor dynamic and static balance ability; ② With the BMI grading, the FRT distance increased, showing a downward trend (P < 0.001). The FRT distance in normal WC patients was significantly higher than that in central obesity patients (P < 0.001), which indicated that the static and dynamic balance ability of central obesity patients was worse than that of normal WC patients; ③ In BMI overweight group, the FRT distance decreased significantly with the increase of WC (P = 0.02). The results showed that under the condition of no difference in BMI, Compared with normal WC, the dynamic and static balance ability of central obese patients was worse; ④ The influence of BESS score on BMI(B=4.12,P =0.027, 95% CI=0.48-7.75)and WC(B = 3.47,P = 0.046, 95% CI = 0.07 - 6.88)was significant. The influence of FRT distance on BMI(B = -5.68,P = 0.001, 95% CI = -8.95 - 2.41)and WC(B = -4.71,P = 0.003, 95% CI = -7.83 to -1.61)was significant, which indicated that the static and dynamic balance ability of obese people was worse with the increase of BMI, and the ability of dynamic and static balance of central obesity was worse than that of normal WC. ConclusionWaist circumference is an independent factor affecting the dynamic and static balance function of overweight and obese people. Under similar BMI, the dynamic balance function of central obese people is worse than that of people with normal waist circumference, leading to higher risk of falling.

ABSTRACT
Objective This study aimed at describing the frequency of rare variants of monogenic cerebral small vessel diseases (CSVD) in a cohort of patients with CSVD, and to explore its clinical relevance. Methods This study included CSVD patients visiting the Neurology Department of Peking Union Medical College Hospital(PUMCH) from March 2017 to January 2022, collecting their demographic and clinical information and DNA samples for whole-exome sequencing. Descriptive analysis and statistical analysis were conducted exploring the differences between monogenic CSVD-related gene mutation carriers and noncarriers. Results A total of 292 patients were included, 51.03% of whom carried one or more rare variants of monogenic CSVD-related genes. The most common rare low-frequency variants were located in the NOTCH3 gene (70 patients, 23.97%), followed by HTRA1 and COL4A1/COL4A2 (22 patients, 7.53%) respectively. Among the subgroup of patients without a family history of stroke (n=176), the frequency of rare variants was as high as 47.16%. Compared with non-carriers, the carriers were diagnosed at a younger age (58.76±13.71 vs. 63.46±13.21, P=0.003). No difference was found in phenotypes among single-SNP carriers, multiple-SNPs carriers, and noncarriers. Conclusions The frequency of rare mutation of monogenic CSVD-related genes were relatively high in Chinese CSVD cohort. The most common rare variant was within the NOTCH3, followed by HTRA1 and COL4A1/COL4A2 genes. For CSVD patients of unknown causes, genetic screening should not be neglected even if there is not a family history of the disease.
ABSTRACT
We presented an adolescent with recurrent intracranial hemorrhage and skin lesion. The diagnosis was unclear and the treatment was difficult. Through a multidisciplinary effort type Ⅰ interferon disease was suspected and later, an interferon-stimulated gene was further detected. Considering the high morbidity and fatality rate of recurrent intracranial hemorrhage, tofacitinib and hydroxychloroquine were administered. After treatment, the livedo reticularis was significantly regressed. Unfortunately, the intracranial hemorrhage recurred due to a pre-existing cerebral aneurysm, leading to death of the patient. The diagnosis and treatment of this case highlight the importance of multidisciplinary collaboration in the diagnosis and treatment of difficult and rare diseases.
ABSTRACT
Objective:To analyze clinical characteristics of patients with novel coronavirus Omicron variant of concern infection, and to provide practical data and experience for subsequent clinical treatment.Methods:A retrospective analysis was performed for the clinical data of 5 cases with novel coronavirus Omicron variant of concern infection treated in the First Hospital of Jiaxing from December 18, 2021 to January 28, 2022. The patients' clinical data were recorded, including gender, age, length of hospital stay, vaccination status, clinical symptoms, laboratory indicators [white blood cell count (WBC), lymphocyte count (LYM), eosinophil count (EOS), hypersensitivity C-reactive protein (hs-CRP), novel coronavirus antibody immunoglobulin (IgG and IgM)], chest CT, treatment course and disease outcome.Results:All 5 patients were male, aged 24-37 years old. Four patients were vaccinated with novel coronavirus vaccine (one patient received 3 doses of the vaccine and 3 patients received only the first 2 doses of the vaccine), and no infection was found in chest CT. Laboratory examination showed that WBC, LYM, EOS and hs-CRP levels were normal, and only showed mild symptoms of upper respiratory tract infection. One patient was not vaccinated with novel coronavirus vaccine, and signs of viral pneumonia could be seen in chest CT, laboratory examination showed that WBC and hs-CRP levels increased, suggesting that bacterial infection, fever, cough, sputum and other respiratory symptoms were obvious, and the treatment time was long. All 5 patients were treated with Chinese medicine Lotus antipyretic and Baihu Yinqiao decoction based on routine antiviral therapy.Conclusions:Patients with novel coronavirus Omicron variant of concern infection vaccinated with the novel coronavirus vaccine have milder clinical symptoms, with less obvious chest CT findings and faster recovery. Chinese medicine Lotus antipyretic and Baihu Yinqiao decoction has obvious therapeutic effect on such patients.
ABSTRACT
Objective:To study the analgesic effect of α-cobratoxin (α-CbTX) on mice and its effect on protein kinase A (PKA) activity of spinal dorsal root ganglion (DRG) in mice.Methods:Healthy male ICR mice( n=102) were randomly divided into low-, medium-, and high-dose α-CbTX groups (1 mg/kg, 3 mg/kg, 9 mg/kg respectively, gavage, n=21), solvent control group (equivalent volume of 0.9% normal saline, gavage, n=21), morphine positive control group (3 mg/kg, intraperitoneal injection, n=6)or aspirin positive control group(300 mg/kg, gavage, n=12). The analgesic effect of α-CbTX was evaluated by hot plate test, acetic acid twisting test and formalin foot licking test. Formalin plantar injection was used to induce pain and then the L4-L6 DRG was taken 30 minutes later. The expression of PKA C-α in L4-L6 DRG of mice were detected by Western blot.SPSS 16.0 software was used for statistical analysis. Repeated measurement ANOVA was used to evaluate the hot plate experimental data, and one-way ANOVA was used for other experimental data. LSD- t test was used for further pairwise comparison. Results:In the hot plate test, the interaction between group and time of mice paw licking latency was significant ( F=8.902, P<0.05). At 0.5 h after administration, the paw licking latencies of α-CbTX medium-dose group ((11.83±1.47)s)and α-CbTX high-dose group (( 14.33±12.1)s) were both longer than that of solvent control group((8.17±0.75) s) ( t=4.461, 7.053, both P<0.05). The efficacy of α-CbTX medium dose group lasted until 1.5 h after administration (all P<0.05), and that of α-CbTX high dose group lasted until 2 h after administration(all P<0.05). In the acetic acid writhing test, the writhing times in the low-, medium- and high-dose α-CbTX group((34.50±3.62) times, (26.17±2.40) times, (13.83±3.76) times)) were significantly lower than that in solvent control group ((42.50±4.59) times) ( t=3.938, 8.040, 14.112, all P<0.05). In the period of the formalin test phase Ⅱ, the total licking time of α-CbTX low-, medium- and high-dose groups ((71.17±6.46) s), (54.67±6.41) s, (40.50±3.89)s) were significantly shorter than that of the solvent control group ((98.67±11.50) s)( t=6.950, 11.120, 14.700, all P<0.05). In the Western blot experiment, compared with solvent control group (0.22±0.01), the levels of PKA C-α in the DRG of mice in low-, medium- and high-dose α-CbTX groups ((0.31±0.02), (0.41±0.03), (0.44±0.02)) were up-regulated ( t=3.140, 6.471, 7.492, all P<0.05). Conclusion:α-CbTX has obvious analgesic effect, and its analgesic mechanism may be related to the activation of PKA.
ABSTRACT
Background@#Different views have been proposed on the radiofrequency treatment modes and parameters of radiofrequency thermocoagulation of the spinal dorsal root ganglion for the treatment of postherpetic neuralgia (PHN). It is urgent to identify a more effective therapy for patients with PHN. @*Methods@#Patients who underwent radiofrequency thermocoagulation therapy for PHN were retrospectively reviewed and were divided into a radiofrequency thermocoagulation (CRF) and double neddles radiofrequency thermocoagulation (DCRF).The pain scores (numerical rating scale, NRS) were evaluated at the following time points: before the operation, 1 day, 3 months, 6 months, 1 year, and 2 years after operation. The incidence of complications and the degree of pain relief were evaluated. The in vitro ovalbumin experiment was used to indicate the effects of radiofrequency thermocoagulation. @*Results@#Compared with the preoperative NRS scores, the postoperative NRS scores decreased significantly; the NRS scores of the DCRF group was lower than that of the CRF group at all time points from 6 months to 2 years following the operation. The total effective rate of the DCRF group was significantly higher than that of the CRF group at 2 years following the operation. The incidence of numbness in the DCRF group was higher than that noted in the CRF group. The ovalbumin experiments in vitro indicated that the effects of radiofrequency thermocoagulation were optimal when the distance between the two needles was 5 mm. @*Conclusions@#DCRF with a 5 mm spacing exhibits a longer duration and higher effective rate in the treatment of PHN and is worth promoting.
ABSTRACT
Objective: To investigate the changes of high density lipoprotein cholesterol (HDL-C) in sepsis patients and its early predictive value for secondary acute kidney injury (AKI) in such patients. Methods: A retrospective case series study was conducted. From June 2019 to June 2021, 232 sepsis patients who met the inclusion criteria were admitted to the Second Hospital of Hebei Medical University, including 126 males and 106 females, aged 24 to 71 years. According to whether complicating secondary AKI, the patients were divided into non-AKI group (n=158) and AKI group (n=74). Data of patients between the two groups were compared and statistically analyzed with independent sample t test or chi-square test, including the sex, age, body mass index (BMI), body temperature, heart rate, primary infection site, combined underlying diseases, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and sepsis-related organ failure assessment (SOFA) score at admission, and the serum levels of C-reactive protein (CRP), procalcitonin, creatinine, cystatin C, and HDL-C measured at diagnosis of sepsis. The multivariate logistic regression analysis was performed on the indicators with statistically significant differences between the two groups to screen the independent risk factors for developing secondary AKI in 232 sepsis patients, and the joint prediction model was established based on the independent risk factors. The receiver operating characteristic (ROC) curve of the independent risk factors and the joint prediction model predicting secondary AKI in 232 sepsis patients were drawn, and the area under the curve (AUC), the optimal threshold, and the sensitivity and specificity under the optimal threshold were calculated. The quality of the above-mentioned AUC was compared by Delong test, and the sensitivity and specificity under the optimal threshold were compared using chi-square test. Results: The sex, age, BMI, body temperature, heart rate, primary infection site, combined underlying diseases, and CRP level of patients between the two groups were similar (P>0.05). The procalcitonin, creatinine, cystatin C, and scores of APACHE Ⅱ and SOFA of patients in AKI group were all significantly higher than those in non-AKI group (with t values of -3.21, -16.14, -12.75, -11.13, and -12.88 respectively, P<0.01), while the HDL-C level of patients in AKI group was significantly lower than that in non-AKI group (t=6.33, P<0.01). Multivariate logistic regression analysis showed that creatinine, cystatin C, and HDL-C were the independent risk factors for secondary AKI in 232 sepsis patients (with odds ratios of 2.45, 1.68, and 2.12, respectively, 95% confidence intervals of 1.38-15.35, 1.06-3.86, and 0.86-2.56, respectively, P<0.01). The AUCs of ROC curves of creatinine, cystatin C, HDL-C, and the joint prediction model for predicting secondary AKI in 232 sepsis patients were 0.69, 0.79, 0.89, and 0.93, respectively (with 95% confidence intervals of 0.61-0.76, 0.72-0.85, 0.84-0.92, and 0.89-0.96, respectively, P values all below 0.01); the optimal threshold were 389.53 μmol/L, 1.56 mg/L, 0.63 mmol/L, and 0.48, respectively; the sensitivity under the optimal threshold were 76.6%, 81.4%, 89.7%, and 95.5%, respectively; the specificity under the optimal threshold values were 78.6%, 86.7%, 88.6%, and 96.6%, respectively. The AUC quality of cystatin C was significantly better than that of creatinine (z=2.34, P<0.05), the AUC quality and sensitivity and specificity under the optimal threshold of HDL-C were all significantly better than those of cystatin C (z=3.33, with χ2 values of 6.43 and 7.87, respectively, P<0.01) and creatinine (z=5.34, with χ2 values of 6.32 and 6.41, respectively, P<0.01); the AUC quality and sensitivity and specificity under the optimal threshold of the joint prediction model were all significantly better than those of creatinine, cystatin C, and HDL-C (with z values of 6.18, 4.50, and 2.06, respectively, χ2 values of 5.31, 7.23, 3.99, 6.56, 7.34, and 4.00, respectively, P<0.05 or P<0.01). Conclusions: HDL-C level in sepsis patients with secondary AKI is significantly lower than that in patients without secondary AKI. This is an independent risk factor for secondary AKI in sepsis patients with a diagnostic value being superior to that of creatinine and cystatin C. The combination of the aforementioned three indicators would have higher predicative valuable for secondary AKI in sepsis patients.

Objective: Solid and micropapillary pattern are highly invasive histologic subtypes in lung adenocarcinoma and are associated with poor prognosis while the biopsy sample is not enough for the accurate histological diagnosis. This study aims to assess the correlation and predictive efficacy between metabolic parameters in (18)F-fluorodeoxy glucose positron emission tomography/computed tomography ((18)F-FDG PET-CT), including the maximum SUV (SUV(max)), metabolic tumor volume (MTV), total lesion glycolysis (TLG) and solid and micropapillary histological subtypes in lung adenocarcinoma. Methods: A total of 145 resected lung adenocarcinomas were included. The clinical data and preoperative (18)F-FDG PET-CT data were retrospectively analyzed. Mann-Whitney U test was used for the comparison of the metabolic parameters between solid and micropapillary subtype group and other subtypes group. Receiver operating characteristic (ROC) curve and areas under curve (AUC) were used for evaluating the prediction efficacy of metabolic parameters for solid or micropapillary patterns. Univariate and multivariate analyses were conducted to determine the prediction factors of the presence of solid or micropapillary subtypes. Results: Median SUV(max) and TLG in solid and papillary predominant subtypes group (15.07 and 34.98, respectively) were significantly higher than those in other subtypes predominant group (6.03 and 10.16, respectively, P<0.05). ROC curve revealed that SUV(max) and TLG had good efficacy for prediction of solid and micropapillary predominant subtypes [AUC=0.811(95% CI: 0.715~0.907) and 0.725(95% CI: 0.610~0.840), P<0.05]. Median SUV(max) and TLG in lung adenocarcinoma with the solid or micropapillary patterns (11.58 and 22.81, respectively) were significantly higher than those in tumors without solid and micropapillary patterns (4.27 and 6.33, respectively, P<0.05). ROC curve revealed that SUV(max) and TLG had good efficacy for predicting the presence of solid or micropapillary patterns [AUC=0.757(95% CI: 0.679~0.834) and 0.681(95% CI: 0.595~0.768), P<0.005]. Multivariate logistic analysis showed that the clinical stage (Stage Ⅲ-Ⅳ), SUV(max) ≥10.27 and TLG≥7.12 were the independent predictive factors of the presence of solid or micropapillary patterns (P<0.05). Conclusions: Preoperative SUV(max) and TLG of lung adenocarcinoma have good prediction efficacy for the presence of solid or micropapillary patterns, especially for the solid and micropapillary predominant subtypes and are independent factors of the presence of solid or micropapillary patterns.

This study was designed to assess the clinical efficacy of oral blood-activating and stasis-removing Chinese patent medicines in treating hypertensive left ventricular hypertrophy(LVH) based on network Meta-analysis. The clinical randomized controlled trials(RCTs) concerning the treatment of hypertensive LVH with oral blood-activating and stasis-removing Chinese patent medicines were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, Web of Science, and Cochrane Library from their inception to September 2021. Two researchers independently completed the literature screening, data extraction, and quality evaluation. The data were then analyzed by RevMan 5.3, Stata 15.1, and ADDIS 1.16.8. Finally, a total of 31 RCTs were included, involving 3 001 patients and four oral blood-activating and stasis-removing Chinese patent medicines. In terms of the alleviation of heart damage, the Chinese patent medicines combined with conventional western medicine groups were superior to the conventional western medicine groups in lo-wering the left ventricular mass index(LVMI). There was no significant difference in LVMI, left ventricular ejection fraction(LVEF), or the ratio of early diastolic peak flow velocity to late diastolic peak flow velocity(E/A) between different Chinese patent medicines combined with conventional western medicine groups. Xinnao Shutong Capsules/Tablets combined with conventional western medicine had the best efficacy in reducing LVMI and elevating LVEF, while Xinkeshu Capsules/Tablets combined with conventional western medicine had the best effect in improving E/A. In the control of blood pressure, when all Chinese patent medicines except for Xinnao Shutong Capsules/Tablets were combined with conventional western medicine, the resulting systolic blood pressure(SBP) and diastolic blood pressure(DBP) were significantly lower than those in the conventional western medicine group. Xinkeshu Capsules/Tablets combined with conventional western medicine produced the best effect in reducing SBP and DBP, followed by Xinnao Shutong Capsules/Tablets. In terms of safety, no serious adverse reactions occurred in all trials. The four oral blood-activating and stasis-removing Chinese patent medicines included in this study exhibited obvious advantages in the treatment of hypertensive LVH when they were combined with conventional western medicine, with the best effects observed in the Xinnao Shutong Capsules/Tablets combined with conventional western medicine group. However, due to the limitation of the quantity and quality of the included articles, the conclusion of this study still needs to be verified by more high-quality, multi-center, and large-sample RCTs.

Objective: To evaluate the nutritional status by the Controlling Nutritional Status (CONUT) score and its association with the long-term prognosis in patients with acute heart failure (AHF). Methods: This prospective monocentric study consecutively enrolled patients admitted to our hospital for AHF from April 2012 to May 2016. Patients were divided into 3 groups based on the CONUT score at admission: normal (0-1), mild malnutrition (2-4) and moderate-severe malnutrition (5-12) groups. Baseline information was obtained and recorded within 24 hours after admission. All patients were followed up every 3 months by outpatient visit or telephone call until March 2019. The primary endpoint was all-cause mortality. The Kaplan-Meier survival curves and log-rank test were used to compare all-cause mortality between groups. Variables showing statistical significance in the univariate analysis were incorporated into multivariate Cox regression model to analyze the independent risk factors for all-cause mortality after discharge. Results: A total of 396 patients were enrolled in this study, including 114 patients with normal nutritional status, 200 patients with mild malnutrition and 82 patients with moderate-severe malnutrition. One hundred and fifty-eight patients died during a median follow-up of 34 (18, 46) months. The mortality was 32.4% (37/114), 39% (78/200) and 52.4% (43/82) in normal, mild malnutrition and moderate-severe malnutrition groups, respectively. The mortality was significantly higher in the moderate-severe malnutrition group than in normal nutrition group (P<0.05). However, there was no significant difference in mortality between normal and mild malnutrition group as well as between mild and moderate-severe malnutrition group (both P>0.05). Kaplan-Meier curves indicated that patients with high CONUT score group was at higher risk of all-cause mortality compared with those with low CONUT score (P=0.002). Cox proportional hazard analyses showed that the risk of all-cause mortality of moderate-severe malnutrition group was significantly higher than that of normal nutrition group (HR =1.648, 95%CI 1.021-2.660, P=0.041). Conclusions: The CONUT score of patients with AHF at admission is associated with the long-term prognosis. High CONUT score is an independent risk factor for all-cause mortality in AHF patients after discharge.

OBJECTIVE@#To evaluate the efficacy of an electro-mechanical film-based(EMFi) multi-parameter pressure sensitive sleep monitor(MPSSM)on clinical diagnosis and research significance of obstructive sleep apnea hypopnea syndrome(OSAHS).@*METHODS@#Retrospective analysis was made of 58 test subjects at Peking University Third Hospital with suspected OSAHS who were simultaneously monitored by MPSSM and polysomnography(PSG). The PSG test results were used as the gold standard in evaluating the sensitivity and specificity of OSAHS diagnosis of MPSSM. The test result consistency of sleep apnea and hypopnea index(AHI)and total apnea time of the two methods was evaluated. Real-time waveform comparison of sleep respiratory events of a randomly selected patient diagnosed with OSAHS was performed.@*RESULTS@#For 58 test subjects, 48 were male, 10 were female, with an average age of(40.6±12.2)years. Thirty-nine out of the 58 test subjects were diagnosed with OSHAS by PSG. The sensitivity of MPSSM for OSAHS diagnosis was 92.3%, with 95% confidence interval of 79.1%-98.4%, and the specificity of MPSSM for OSAHS diagnosis was 100%, with 95% confidence interval of 82.3%-100%. Kappa test k=0.887 (P < 0.001) showed OSAHS diagnosis results of the two methods were almost identical. The AHI measured by MPSSM [12.0(2.6-32.2) times/h] and PSG [13.4(3.1-38.8) times/h] were highly correlated (ρ=0.939, P < 0.001). The total apnea time measured by MPSSM [37.9(9.9-80.5) min] and PSG [32.3(8.6-93.0) min] were highly correlated(ρ=0.924, P < 0.001). Bland-Altman plot showed that the consistency between the test results of the two methods was very high.@*CONCLUSION@#As a portable, non-contact, fully automatic monitoring device, MPSSM is reliable in the screening of OSAHS compared with PSG. It is suitable to be promoted and applied in primary medical institutions, nursing homes and domestic usage. However, further research is required in improving the analysis of different sleep phase and the differentiation of central sleep apnea syndrome respiratory events in order to effectively assist medical personnel in making an accurate sleep apnea diagnosis.

OBJECTIVE@#LncRNA ITGB2-AS1 has been found to play important roles in the occurrence and development of human solid tumors. However, its role in hematological diseases, especially acute myeloid leukemia (AML), remains unclear. The aim of this study was to identify the expression pattern of ITGB2-AS1 in AML patients and to further explore its clinical significance.@*METHODS@#ITGB2-AS1 expression was analyzed in public datasets (including TCGA and GSE63270) and further validated in a cohort of 109 AML patients by real-time quantitative PCR (RT-qPCR).@*RESULTS@#The level of ITGB2-AS1 was up-regulated among two independent cohorts (TCGA, P<0.05; GSE63270, P<0.05), which was confirmed by the data from 109 AML patients enrolled in this study (P<0.05). Clinically, high ITGB2-AS1 expression was associated with older age (P=0.023) and lower complete remission (CR) rate (P=0.005). Multivariate analysis identified that high ITGB2-AS1 expression was an independent prognostic factor not only for CR rate (P=0.027) but also for overall survival (OS) time (P=0.011), and ITGB2-AS1 was positively correlated with ITGB2 expression in both TCGA (r=0.74, P<0.001) and clinical data detected in this study (r=0.881, P<0.001). High ITGB2 expression was also associated with older age (P=0.02) and lower CR rate (P=0.020). Moreover, high ITGB2 expression predicted worse OS (P=0.028).@*CONCLUSION@#ITGB2-AS1 is overexpressed in AML and predicts poor prognosis in AML patients.

Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare but increasingly recognized subtype of CAA. CAA-RI consists of two subtypes: inflammatory cerebral amyloid angiopathy and amyloid β (Aβ)-related angiitis. Acute or subacute onset of cognitive decline or behavioral changes is the most common symptom of CAA-RI. Rapid progressive dementia, headache, seizures, or focal neurological deficits, with patchy or confluent hyperintensity on T2 or fluid-attenuated inversion recovery sequences and evidence of strictly lobar microbleeds or cortical superficial siderosis on susceptibility-weighted imaging imply CAA-RI. The gold standard for diagnosis is autopsy or brain biopsy. However, biopsy is invasive; consequently, most clinically diagnosed cases have been based on clinical and radiological data. Other diagnostic indexes include the apolipoprotein E ε4 allele, Aβ and anti-Aβ antibodies in cerebral spinal fluid and amyloid positron emission tomography. Many diseases with similar clinical manifestations should be carefully ruled out. Immunosuppressive therapy is effective both during initial presentation and in relapses. The use of glucocorticoids and immunosuppressants improves prognosis. This article reviews the pathology and pathogenesis, clinical and imaging manifestations, diagnostic criteria, treatment, and prognosis of CAA-RI, and highlights unsolved problems in the existing research.

Objective:To explore whether there were changes in midbrain morphology related to motor function in patients with cerebral small vessel disease (CSVD).Methods:The study was conducted on a subset of patients with CSVD registered at the Department of Neurology of Peking Union Medical College Hospital from 2010 to 2018. All magnetic resonance imaging images were taken with a 3.0 T nuclear magnetic resonance imager. The measurement of anteroposterior diameter of the mesencephalon and the tegmentum of mesencephalon was performed on a personal computer with the image processing software RadiAnt DICOM Viewer. Several clinical manifestations of dyspraxia, dysphagia, dysarthria and dysuria were evaluated by interviewing the patient and family members living with the patient. Kinect depth camera combined with self-developed software platform was used to conduct quantitative evaluation of patients′ motor function. Three parameters, namely walking speed, walking time of three meters and time of standing up and sitting down, were selected from the obtained parameters. SPSS 17.0 software was used for statistical analysis.Results:A total of 176 patients were included, aged 30-88 (64.16±11.57) years. One hundred and fifteen patients were males, accounting for 65.34%. In patients with CSVD, anteroposterior diameter of the mesencephalon and the tegmentum of mesencephalon were negatively correlated with age ( B=-0.032, P<0.001; B=-0.020, P=0.006). The anteroposterior diameter of the mesencephalon was negatively correlated with symptoms of dyskinesia ( OR=0.006, 95% CI 0-0.135, P=0.001), even when the age and gender were adjusted ( OR=0.014,95% CI 0-0.416, P=0.013). The anteroposterior diameter of the mesencephalon was negatively correlated with symptoms of dysuria ( OR=0.046,95% CI 0.002-0.936, P=0.045), but no longer correlated when the age and gender were adjusted. The anteroposterior diameter of tegmentum of mesencephalo was also negatively correlated with symptoms of dyskinesia ( OR=0.035,95% CI 0.002-0.684, P=0.027), but no longer correlated after adjusting for age and gender. Video recording and evaluation of motor function were performed on 87 patients. Spearman correlation analysis showed that none of the three motor function scores was correlated with age or gender. The anteroposteric diameter of the midbrain was positively correlated with walking speed ( r=0.231 ,P=0.040) and negatively correlated with walking time of three meters ( r=-0.304, P=0.005), but not with standing up and sitting down time, while the anteroposteric diameter of tegmentum of mesencephalo was not correlated with all of them. Conclusion:There are changes in mesencephalon morphology in patients with CSVD, structural parameters of mesencephalon are related to motor function and urination function, and mesencephalon atrophy may be an independent related factor for symptoms of dyskinesia in patients with CSVD.
ABSTRACT
@#Introduction: Chronic pain remains a public health issue as patients endure this condition while it affects the patients’ life either physically or mentally. Evidence has demonstrated that depression coexist with chronic pain; yet depression is often insufficiently acknowledged, indirectly causing this mental health problem to be undertreated. In this paper we aim to determine the local prevalence of depression among patients with chronic pain in a tertiary hospital in Sabah, East Malaysia. Methods: This is a retrospective cross-sectional study. Past patient consultation records of adult patients who attended a tertiary pain clinic in Sabah for the first time are included. Socio-demographic data were collected, as well as scores from painDetect Questionnaire (PD-Q) and 9-item Patient Health Questionnaire (PHQ-9). Results: From the 222 individual data collected, more than half (64.9%) were female. 79 (35.6%) were between the age of 18 to 40. The types of pain presented were almost equally distributed between nociceptive pain (38.3%), mixed pain (33.3%) and neuropathic pain (28.4%). Prevalence of depression among chronic pain patients was 15%. Patients with neuropathic pain are significantly associated with signs of depression (p<0.001). Female patients are significantly more prone to depression as compared to male (p = 0.024). Conclusion: The high prevalence of depression among chronic pain patients warrants the attention of physicians. Physicians should be vigilant and actively screen for depression in patients with chronic pain.
ABSTRACT
Blakeslea trispora is a natural source of carotenoids, including β-carotene and lycopene, which have industrial applications. Therefore, classical selective breeding techniques have been applied to generate strains with increased productivity, and microencapsulated β-carotene preparation has been used in food industry (Li et al., 2019). In B. trispora, lycopene is synthesized via the mevalonate pathway (Venkateshwaran et al., 2015). Lycopene cyclase, which is one of the key enzymes in this pathway, is a bifunctional enzyme that can catalyze the cyclization of lycopene to produce β-carotene and exhibit phytoene synthase activity (He et al., 2017).
