ObjectiveTo explore the quality differences between steamed products and raw products of Citri Reticulatae Pericarpium(CRP). MethodThe color of steamed products and raw products of CRP was determined from the perspective of appearance by electronic eye technique, and the quality differences between them was objectively characterized by the luminous value(L*), yellow-blue value(b*), red-green value(a*) and total chromatic value(E*ab). Based on this, ultra-high performance liquid chromatography(UPLC) was used to establish a fingerprint evaluation method with the mobile phase of acetonitrile(A)-0.1% formic acid aqueous solution(B) for gradient elution(0-5 min, 5%A; 5-30 min, 5%-20%A; 30-60 min, 20%-52%A), detection wavelength at 270 nm, flow rate of 0.3 mL·min-1 and column temperature of 30 ℃. The quality differences between steamed products and raw products of CRP were compared from the perspective of chemical composition, and correlation analysis was used to reveal the correlation between the difference in appearance color and the difference in internal chemical composition. ResultAfter being steamed, L*, b* and E*ab of CRP showed an overall decreasing trend, indicating that the color of the steamed products darkened and deepened from yellow to blue but still tended to be yellow, while a* showed an overall increasing trend, indicating that the color of the steamed products tended to red. A total of 24 peaks were identified in the fingerprint profiles of raw products and steamed products of CRP, and 13 of the main peaks were identified. The precision, stability and repeatability studies showed that compared with the reference peak (peak 14, hesperidin), the relative standard deviations(RSDs) of the relative peak area and relative retention time of the remaining peaks were<3.0%.The results of chemometric statistical analysis showed that there were some differences between raw products and steamed products of CRP, and 7 main differential components were identified, among which 5-hydroxymaltol(peak 1) and 5-hydroxymethylfurfural(peak 2) were the characteristic components of steamed products. The correlation analysis results showed that, in addition to the above two characteristic components, four components of peak 4, peak 10 (vicenin-2), peak 23 (tangeretin) and peak 24 (5-demethylnobiletin) also correlated significantly with the color change (E*ab) of the samples (P<0.05, P<0.01). ConclusionBefore and after steaming, not only the chemical composition changes, but also the color. Comparing the characteristic peaks of chemical composition difference and color difference before and after steaming of CRP, it is found that 5-hydroxymaltol, 5-hydroxymethylfurfural and peak 4 are common characteristic difference components, which can provide a reference for establishing the characteristic quality control method of steamed products, and quickly evaluating the quality difference between raw products and steamed products of CRP.

Background:
Acne vulgaris (AV) is a common adolescent skin condition which is mainly caused by Cutibacterium acnes overcolonization and subsequent inflammation.
Objective:
Our previous studies demonstrated that ethanol extracts of Meconopsis quintuplinervia Regel (EMQ) possess significant antimicrobial properties. However, their protective effects and potential mechanisms against AV remain unclear.
Methods:
In the present study, the EMQ treatment potential for AV was evaluated in a C.acnes-induced mouse ear edema model, and the EMQ anti-inflammatory mechanism was evaluated in lipopolysaccharide (LPS)-induced RAW264.7 macrophage cells.
Results:
The results showed that EMQ alleviated edema formation and inflammatory cell infiltration in an acne mouse model by suppressing inflammatory cytokines interleukin (IL)-6, IL-1β, and tumor necrosis factor α expression. Moreover, EMQ inhibited the phosphorylation of MAP kinases (MAPKs) such as p38, JNK, and ERK, the phosphorylation and degradation of IκB-α and the nuclear translocation of nuclear factor kappa B (NF-κB) p65 in LPS-induced RAW264.7 cells.
Conclusion
These findings suggest the potent anti-inflammatory activity of EMQ is possibly through the regulation of the MAPKs and NF-κB signaling pathways. Inhibition of C. acnes activity combined with a powerful anti-inflammatory effect of EMQ indicated its potential as a novel therapeutic option for AV.

Cerebral venous sinus thrombosis (CVST) is a rare type of cerebrovascular disease, accounting for about 0.5% of all strokes. About 4% of patients with CVST have supratentorial brain parenchymal lesions and brain edema sufficient to cause brain hernia and neurological deterioration, which is called malignant CVST. Malignant CVST refers to the clinical (loss of consciousness, unilateral or bilateral pupil dilation) and imaging signs of supratentorial cortical lesions (ischemia or hemorrhage) accompanied by tentorial hiatal hernia formation at the onset or after treatment with heparin. For patients with malignant CVST, decompressive craniectomy is not only a life-saving treatment, but also can make most patients achieve good functional outcome.

OBJECTIVE To establish the fingerprint and multi-component content determination method of Crataegus pinnatifida leaves from different producing areas, and to evaluate the quality of C. pinnatifida leaves and screen the differential markers. METHODS Seventy-eight batches of C. pinnatifida leaves were collected from Chengde of Hebei Province, Huludao of Liaoning Province, Yuncheng of Shanxi Province and Linyi of Shandong Province. High-performance liquid chromatography (HPLC) and Similarity Evaluation System for Traditional Chinese Medicine Chromatographic Fingerprints (2012 edition) were used to draw the fingerprints and conduct similarity evaluation. Grey correlation analysis, cluster analysis (CA), principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) were performed by using SPSS 19.0, MetaboAnalyst 5.0 and SIMCA 14.1 software. The differential markers affecting the quality of C. pinnatifida leaves were screened with variable importance in the projection (VIP) value greater than 1 and the error line not exceeding the origin as the criterion. Using vitexin rhamnoside as an internal reference, the contents of chlorogenic acid, glucosylvitexin, hypericin and isoquercetin in 78 batches of C. pinnatifida leaves were determined by the same HPLC combined with quantitative analysis of multi- components by single-marker (QAMS), and the results were compared with external standard method. RESULTS Eight common peaks were calibrated in the fingerprints for 78 batches of C. pinnatifida leaves from 4 producing areas. Five known components were identified, including chlorogenic acid (peak 1), glucosylvitexin (peak 3), vitexin rhamnoside (peak 4), hypericin (peak 7) and isoquercetin (peak 8); their similarities ranged from 0.871 to 0.998. Average relative correlations of samples from Chengde of Hebei Province, Huludao of Liaoning Province, Yuncheng of Shanxi Province and Linyi of Shandong Province were 0.538, 0.528, 0.462 and 0.435, respectively. CA and PCA showed that the samples from Chengde of Hebei Province and Huludao of Liaoning Province were roughly classified into one category, while the samples from Linyi of Shandong Province and Yuncheng of Shanxi Province were roughly classified into one category; VIP values of peak 1, 2, 3 and 5 were all greater than 1. By QAMS, the relative correction factors of chlorogenic acid, glucosylvitexin, hypericin and isoquercetin were 0.401, 0.993, 1.670 and 1.615 (RSD<2%). Compared with external standard method, except for isoquercetin in the two batches of samples (S39 and S41), there was no significant difference in the content of each component in other batches of samples (the relative deviations≤ 5%). CONCLUSIONS The established fingerprint and QAMS method are simple to operate and can be used to evaluate the quality of C. pinnatifida leaves. The sample from Chengde of Hebei Province is relatively good in quality. Chlorogenic acid (peak 1), glucosylvitexin (peak 3), and the corresponding components of peaks 2 and 5 may be differential markers affecting the quality of C. pinnatifida leaves.

Objective:To investigate the awareness of diabetes knowledge among the health examination population and its influencing factors.Methods:A cross-sectional study. From september to november 2022, the subjects of six health examination centers located in six different cities (Beijing, Shanghai, Tianjin, Chongqing, Xiamen, Hangzhou) in China were investigated in the form of questionnaires to investigate the awareness of diabetes core information and the level of trust to different information sources of diabetes knowledge. According to the questionnaire results, the subjects were divided into a high awareness group of diabetes core information and a low awareness group. Logistic regression was used to analyze the influencing factors of diabetes core information awareness; the t-test was used to compare the trust degree of the two groups to different information sources. Results:A total of 9 315 people were included in the six centers, including 4 932 men (52.90%) with an average age of (39.36±12.64) years and 4 383 women (47.10%) with a mean age of (37.47±11.85) years. Only 36% of the people had high awareness of diabetes core information; variables such as gender, age, education level, physical examination frequency in the past three years, package price of this physical examination, self-evaluation of diabetes knowledge, diabetes status, and city of residence were variables that affect the level of awareness of core information related to diabetes (all P<0.05). Compared with the low awareness group of diabetes core information, the high awareness group trusted professional medical staff ( t=-9.597, P<0.05) and community health promotion more ( t=-5.014, P<0.05), but did not trust the emerging popular science propaganda means, such as WeChat official accounts/WeChat groups/QQ groups, Internet web page, Tiktok/Kwai and other short video APPs. Conclusion:The awareness rate of diabetes knowledge among the health examination population is low, and it is affected by many factors; Health education on diabetes knowledge should be carried out for people undergoing physical examination.

Objective:To analyze the risk factors of major adverse kidney events within 30 days (MAKE30) in patients with acute pancreatitis (AP).Methods:A retrospective cohort study was conducted. A total of 162 patients who were first diagnosed with AP in the First Affiliated Hospital of Soochow University from June 2019 to June 2021 and the onset time was less than 72 hours were enrolled. Patients were divided into MAKE30 group and non-MAKE30 group according to the occurrence of MAKE30 after hospitalization. MAKE30 was defined as death from any cause, new renal replacement therapy (RRT), and persistent renal insufficiency (PRD). The clinical data of the two groups at admission were compared. The independent risk factors of MAKE30 were analyzed by multivariate Logistic regression method, and a regression equation was established as a quantitative prediction model of MAKE30. Receiver operator characteristic curve (ROC curve) was drawn to analyze the prediction of the quantitative prediction model value.Results:All 162 patients were included in the final analysis, including 32 in the MAKE30 group and 130 in the non-MAKE30 group. Univariate analysis showed that compared with the non-MAKE30 group, the body mass index (BMI), the proportion of severe AP, and the acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, the sequential organ failure assessment (SOFA) score, blood urea nitrogen (BUN), serum creatinine (SCr), C-reactive protein (CRP), HCO 3-, Cl - levels and the proportion of hyperchloremia at admission in the MAKE30 group were significantly increased. Multivariate Logistic regression analysis showed that APACHE Ⅱ score at admission [odds ratio ( OR) = 1.659, 95% confidence interval (95% CI) was 1.426-1.956, P = 0.009], SOFA score ( OR = 1.501, 95% CI was 1.236-1.840, P = 0.014) and hyperchloremia ( OR = 1.858, 95% CI was 1.564-2.231, P = 0.004) were independent risk factors for MAKE30 in AP patients. The MAKE30 regression equation was established by the above risk factors [Logit( P) = 0.063+0.525×APACHEⅡ score+0.328×SOFA score+0.895×hyperchloremia], which was used as the MAKE30 quantitative prediction model. ROC curve analysis showed that the area under the ROC curve (AUC) of the model for predicting MAKE30 was 0.846 (95% CI was 0.774-0.923, P = 0.001). The patients were divided into two subgroups with hyperchloremia (Cl -≥110 mmol/L, n = 19) and non-hyperchloremia (Cl - < 110 mmol/L, n = 143) according to the blood Cl - level at admission. The incidence of MAKE30 and acute kidney injury (AKI) in the hyperchloremia group was significantly increased (MAKE30: 68.4% vs. 13.3%, AKI: 89.5% vs. 43.4%), and the levels of BUN and SCr at admission were significantly increased [BUN (mmol/L): 9.3±2.5 vs. 5.9±1.1, SCr (μmol/L): 162.3±26.4 vs. 78.6±9.2], the total length of hospital stay and length of intensive care unit (ICU) stay were significantly longer [total length of hospital stay (days): 10.2±1.6 vs. 5.6±1.2, length of ICU stay (days): 6.2±1.0 vs. 3.1±0.6], the cumulative intravenous infusion volume increased significantly at 48 hours and 72 hours (mL: 7 235.9±1 025.3 vs. 5 659.6±956.7 at 48 hours, 11 052.6±1 659.8 vs. 7 156.9±1 052.4 at 72 hours), differences were statistically significant (all P < 0.01). Conclusions:MAKE30 can be used as an important indicator to evaluate the short-term clinical prognosis of AP patients. APACHEⅡ score, SOFA score and hyperchloremia at admission are the main risk factors. The risk model of MAKE30 based on these three indicators has good predictive performance. AP patients with hyperchloremia are at high risk of developing MAKE30, which should be highly regarded in clinical practice.

Objective:To explore the effect of visual processing patterns on emotional face processing in patients with Alzheimer's disease (AD).Methods:From June 2020 to August 2021, twenty-two AD patients (AD group) who met the conditions of this study were selected from the memory impairment clinic of the First Affiliated Hospital of Anhui Medical University, and demographically matched twenty-one elderly healthy people (control group) were selected from the patients' family members and community residents. The two groups of subjects performed emotional face visual scanning and facial recognition experiments after completing the evaluation of the cognitive scale and eye movement data were recorded in the emotional face visual scanning task. Statistical analysis of the obtained results was performed using SPSS 23.0 Windows version software. The data that conformed to the normal distribution were tested by independent samples t-test and variance analysis, and the data that did not conform to the normal distribution were tested by nonparametric test. Results:(1)In the emotional face recognition task, the total accuracy of facial emotion recognition of AD patients(0.52(0.42, 0.59)) was lower than that of the normal control group(0.67(0.64, 0.69)), and the difference was statistically significant( Z=-4.023, P<0.01), which was mainly manifested in recognizing complex facial emotion. (2) In the emotional face visual processing task, the saccade count ((1.96±0.97), (2.50±0.44)), fixation count ((3.93±2.58), (6.37±2.08))and fixation time ((1 205.89±727.32)s, (1 761.38±525.54)s)of AD patients were lower than those of the control group( t=-2.314, -3.402, -2.880, all P<0.05), and the surrounding facial fixation time (384.95 (276.51, 587.78)s, 276.06 (190.03, 384.55)s) was higher than that of the control group( Z=-2.478, P=0.013). Patients with AD had a lower fixation count than that in the control group on the eye area of surprise ((3.76±2.90), (6.25±2.19)), anger ((4.48±2.72), (7.06±2.55)) and disgust ((4.10±2.45), (6.67±2.45)), and the differences were statistically significant ( t=-3.164, -3.207, -3.436, all P<0.05). Patients with AD had a lower fixation time than those of the control group on the eye area of surprise ((1 150.26±753.22)s, (1 779.91±551.66)s), angry ((1 430.85±869.52)s, (1 944.51±612.63)s) and disgust ((1 266.14±765.67)s, (1 898.33±676.02)s), and the differences were statistically significant ( t=-3.115, -2.247, -2.865, all P<0.05). (3) Spearman correlation analysis showed that the accuracy of overall emotional face recognition was positively correlated with the fixation time in the eye area in AD patients ( r=0.429, P<0.05). Conclusion:The impaired visual processing of AD patients causes emotional face recognition disorders. Therefore, AD patients have different visual processing patterns in emotional face processing than age-matched normal controls, mainly manifested as the decreased fixation on the eye area.

Objective:To observe the effect of combining transcranial direct current stimulation (tDCS) with functional electrical stimulation-assisted cycling (FES-cycling) on lower limb motor function early after a stroke.Methods:Thirty-seven survivors of a recent stroke were divided into a tDCS treatment group ( n=18) and a pseudo-stimulation group ( n=19). While receiving routine rehabilitation training and clinical drug treatment, the tDCS treatment group also cycled in response to functional electrical stimulation while simultaneously receiving tDCS anode stimulation of the motor cortex M1 area. The pseudo-stimulation group followed the same protocol but with the tDCS stimulation inactivated. Both groups were treated for 20min daily, 5 days weekly for 4 weeks. Before and after the 4 weeks of treatment, the lower limb motor function, walking ability and ability in the activities of daily living of both groups were evaluated using the Fugl-Meyer assessment scale for the lower extremities (FMA-LE), the timed up and go test (TUGT) and the modified Barthel index (MBI) respectively. Transcranial magnetic stimulation was used to detect each subject′s cerebral cortex motor threshold (CMT) , cortical latency (CL) and central motor conduction time (CMCT) as well as the amplitude (Amp) of the motor evoked potential of the lower limb primary motor cortex (M1 area). Results:After 4 weeks of treatment, the average FMA-LE and MBI scores and TUGT times of the two groups had improved significantly compared with those before treatment. The average FMA-LE score and TUGT time of the tDCS group were significantly better than those of the pseudo-stimulation group. The average CMT, CL and CMCT in both groups were significantly lower than those before the intervention, while the average Amp had increased significantly, but there were significant differences in the average CMT, Amp, CL and CMCT between the two groups after the 4 weeks of treatment.Conclusions:Transcranial direct current stimulation combined with cycling assisted by functional electrical stimulation can effectively stimulate excitability in the motor cortex soon after a stroke. That should promote the recovery of nerve activity and lower limb function.

Objective:To compare the effects of intravenous anesthesia between propofol and etomidate in patients undergoing laparoscopic surgery and their effects on plasma nitric oxide (NO) and endothelin-1 (ET-1).Methods:The clinical data of 80 patients with laparoscopic surgery in Guangrao People′s Hospital from March 2017 to March 2019 were retrospectively analyzed. Among them, 40 cases were given propofol intravenous anesthesia (propofol group), and 40 cases were given etomidate intravenous anesthesia (etomidate group). The anesthetic effect, plasma NO and ET-1 levels, hemodynamic indexes and adverse reactions (muscle spasm, nausea and vomiting, injection site pain, body movement and respiratory depression) were compared between the two groups.Results:The time of consciousness disappearance, tracheal intubation, eye opening, spontaneous breathing and speech response in etomidate group were significantly shorter than those in propofol group: (57.48 ± 2.63) s vs. (86.17 ± 7.41) s, (4.39 ± 2.56) min vs. (6.42 ± 2.58) min, (5.39 ± 2.56) min vs. (9.42 ± 2.58) min, (5.21 ± 1.99) min vs. (8.75 ± 2.54) min and (8.39 ± 2.56) min vs. (8.39 ± 2.56) min, and the differences were statistically significant ( P<0.05). The levels of NO and ET-1 in the etomidate group were significantly lower than those in the propofol group at 0.5, 1.0 and 1.5 h after pneumoperitoneum ( P< 0.05). The levels of systolic blood pressure, diastolic blood pressure and oxygen saturation (SpO 2) in the etomidate group were significantly higher than those in the propofol group: (78.42 ± 4.68) mmHg (1 mmHg = 0.133 kPa) vs. (74.11 ± 6.63) mmHg, (132.86 ± 8.71) mmHg vs. (111.24 ± 3.56) mmHg and 0.982 ± 0.032 vs. 0.953 ± 0.043, and the differences were statistically significant ( P<0.05). The incidence of adverse reactions in the etomidate group was significantly lower than that in the propofol group: 17.5% (7/40) vs. 47.5% (19/40), P<0.05. Conclusions:Compared with propofol intravenous anesthesia, etomidate intravenous anesthesia in laparoscopic surgery patients has more stable hemodynamics and better anesthetic effect. It can effectively inhibit the release of NO and ET-1, and has higher safety.
