ObjectiveTo explore the possible action mechanism of Qingshi Anti-itch Ointment （青石止痒软膏， QAO） in the treatment of psoriasis. MethodsForty mice were randomly divided into four groups， blank group， model group， calcipotriol group and QAO group， with 10 mice in each group. Except for the blank group， psoriasis was induced by applying imiquimod cream to the dorsal skin. After modeling for 6 hours daily， the calcipotriol group and QAO group were treated with 0.5 g of calcipotriol ointment or 0.5 g of QAO， respectively， applied to the treated dorsal skin. The blank group and the model group received no treatment. The skin lesions were observed， and the psoriasis area and severity index （PASI） score was assessed every other day. After 7 days， Hematoxylin and Eosin （HE） staining was performed on dorsal skin tissue to observe pathological changes. The levels of interleukin 1β （IL-1β） and interleukin 18 （IL-18） were determined by enzym-linked immunosorbent assay （ELISA）. The protein levels of Caspase-1，Pro-Caspase-1， gasdermin D （GSDMD） and gasdermin-D-N （GSDMD-N） were detected by Western Blot （WB）. The protein levels of GSDMD were observed by immunohistochemistry. ResultsCompared with the blank group， the model group mice showed redness， erythema， and white scales on their skin， with histological observations indicating epidermal thickening， elongated spines， and infiltration of inflammatory cells. The PASI scores of the skin tissue on days 1， 3， 5， and 7 were elevated； the IOD and AOD values of GSDMD protein increased； the protein levels of Caspase-1， Pro-Caspase-1，GSDMD， GSDMD-N， and IL-1β and IL-18 were significantly elevated （P＜0.05 or P＜0.01）. Compared with the model group， the QAO group and calcipotriol group showed lighter skin lesions； the PASI scores on day 5 and day 7 in the QAO group， and on day 3， 5， and 7 in the calcipotriol group， were reduced； the IOD and AOD values of GSDMD protein， and the protein level of Caspase-1， GSDMD， and GSDMD-N， as well as level of IL-18 and IL-1β decreased in both groups； in the calcipotriol group， Pro-Caspase-1 protein level also decreased （P＜0.05 or P＜0.01）. Compared with the calcipotriol group， the QAO group showed slightly redder skin， more obvious thickening of the stratum corneum， and less capillary dilation； the PASI scores on day 3 and day 7 increased， while the score on day 5 was reduced； the protein level of Pro-Caspase-1， GSDMD， GSDMD-N， and the level of IL-18 and IL-1β were increased in the QAO group （P＜0.05）. ConclusionQAO can effectively relieve psoriasis dermatitis in mice. Its potential mechanism may be related to the regulation of the Caspase-1/GSDMD protein pathway， down-regulation of IL-18 and IL-1β levels， and alleviation of pyroptosis.

ObjectiveTo observe the clinical efficacy and safety of Modified Guomin Decoction （加味过敏煎， MGD） in patients with mild to moderate atopic dermatitis （AD） of the traditional Chinese medicine （TCM） pattern of heart fire and spleen deficiency， and to explore its possible mechanisms. MethodsIn this randomized， double-blind， placebo-controlled study， 72 patients with mild to moderate AD and the TCM pattern of heart fire and spleen deficiency were randomly divided into a treatment group and a control group， with 36 cases in each group. The treatment group received oral MGD granules combined with topical vitamin E emulsion， while the control group received oral placebo granules combined with topical vitamin E treatment. Both groups were treated twice daily for 4 weeks. Clinical efficacy， TCM syndrome scores， Visual Analogue Scale （VAS） for pruritus， Dermatology Life Quality Index （DLQI） scores， Scoring Atopic Dermatitis （SCORAD） and serum biomarkers， including interleukin-33 （IL-33）， interleukin-1β （IL-1β）， immunoglobulin E （IgE）， and tumor necrosis factor-α （TNF-α） were compared before and after treatment. Safety indexes was also assessed. ResultsThe total clinical effective rates were 77.78% （28/36） in the treatment group and 38.89% （14/36） in the control group， with cure rates of 19.44% （7/36） and 2.78% （1/36）， respectively. The treatment group showed significantly better clinical outcomes compared to the control group （P＜0.05）. The treatment group exhibited significant reductions in total TCM syndrome scores， including erythema， edema， papules， scaling， lichenification， pruritus， irritability， insomnia， abdominal distension， and fatigue scores， as well as reductions in VAS， DLQI， SCORAD， and serum IgE and IL-33 levels （P＜0.05 or P＜0.01）. Compared to the control group， the treatment group had significantly better improvements in all indicators except for insomnia （P＜0.05）. No adverse events occurred in either group. ConclusionMGD is effective and safe in treating mild to moderate AD patients with heart fire and spleen deficiency pattern. It significantly alleviates pruritus， improves TCM syndromes and quality of life， and enhances clinical efficacy， possibly through modulation of immune responses.

Based on the discussion of "eight weak areas" in The Inner Canon of Yellow Emperor （《黄帝内经》）， combined with the typical rash manifestations of atopic dermatitis， it is believed that atopic dermatitis is mostly deficiency-excess complex， and that pathogens intruding eight weak areas are the core of its pathogenesis. The external cause is exterior deficiencies， with heat， wind， dampness and other pathogenic qi attacking. The heart， lungs， kidneys out of balance， and excess pathogen are the internal cause， in which fire constraint and excessive heat are the basis of the disease， the wind invading leads to the progress of the changes， dampness obstructing channels and colla-terals make the condition persistent. Internal and external pathogens combination and retention result to the course of the disease lingering and difficult to cure. The internal treatment is to regulate zang-fu organs， and the formula could use self-prescribed modified Qingrun Tongluo Decoction （清润通络汤）， clearing heart and reducing fire in order to clear the heat and cool the blood， moistening lungs and generating metal to consolidate the exterior and dispel the wind， and nourishing kidneys and draining water to dispel the dampness and activate the collaterals. The external treatment applies maceration， fire acupuncture， wrapping to dredge the eight weak areas and regulate qi and blood in channel， so as to expel pathogens.

ObjectiveTo evaluate the clinical efficacy and safety of Huaban Jiedu Formulation （化斑解毒方， HJF） in treating psoriasis vulgaris with blood-heat syndrome. MethodsA randomized， double-blind， placebo-controlled study was conducted with 60 patients diagnosed with psoriasis vulgaris of blood-heat syndrome. Patients were randomly assigned to either a treatment group or a control group， with 30 cases in each. The treatment group received HJF granules orally， one dose a day， combined with topical Qingshi Zhiyang Ointment （青石止痒软膏）， while the control group received placebo granules， one dose a day， combined with the same topical ointment. Both groups were topically treated twice daily of 28 days treatment cours. Psoriasis area and severity index （PASI）， visual analogue scale for pruritus （VAS）， traditional Chinese medicine （TCM） syndrome scores， dermatology life quality index （DLQI）， and psoriasis life stress inventory （PLSI） were assessed before treatment and on day 14 and day 28. Response rates for PASI 50 （≥50% reduction） and PASI 75 （≥75% reduction）， as well as overall clinical efficacy， were compared between groups. Serum levels of interleukin-6 （IL-6） and interleukin-17 （IL-17） were measured before and after 28 days of treatment. Adverse reactions during treatment were recorded. ResultsAfter 28 days of treatment， both groups showed significant reductions in PASI total score， lesion area score， erythema， scaling， and infiltration scores， pruritus VAS score， TCM syndrome score， DLQI， PLSI， and serum IL-6 and IL-17 levels （P＜0.05）. Compared to the control group， the treatment group had significantly greater improvements in PASI total score and erythema score， TCM syndrome score， serum IL-6 and IL-17 levels， and PASI 50 response rate after 28 days （P＜0.05）. Between-group comparisons of score differences before and after 28-day treatment revealed that the treatment group showed significantly better improvements in PASI total， lesion area score， erythema score， TCM syndrome score， DLQI， PLSI， and inflammatory markers （P＜0.05 or P＜0.01）. The total effective rate on day 14 and day 28 was 40.00% （12/30） and 83.33% （25/30） in the treatment group， versus 6.90% （2/29） and 41.38% （12/29） in the control group， respectively. The clinical efficacy in the treatment group was significantly superior to that in the control group （P＜0.05）. Mild gastric discomfort occurred in 3 patients in the treatment group and 1 in the control group. ConclusionHJF can effectively improve skin lesions and TCM symptoms relieve pruritus， enhance quality of life， and reduce inflammatory markers IL-6 and IL-17， in patients with blood-heat syndrome of psoriasis vulgaris， with a good safety profile.

Objective:To explore the optimal pulse oxygen saturation (SpO 2) range during hospitalization for patients with sepsis. Methods:A case-control study design was employed. Demographic information, vital signs, comorbidities, laboratory parameters, critical illness scores, clinical treatment information, and clinical outcomes of sepsis patients were extracted from the Medical Information Mart for Intensive Care-Ⅳ (MIMIC-Ⅳ). A generalized additive model (GAM) combined with a Loess smoothing function was employed to analyze and visualize the nonlinear relationship between SpO 2 levels during hospitalization and in-hospital all-cause mortality. The optimal range of SpO 2 was determined, and Logistic regression model along with Kaplan-Meier curve were utilized to validate the association between the determined range of SpO 2 and in-hospital all-cause mortality. Results:A total of 5?937 patients met the inclusion criteria, among whom 1?191 (20.1%) died during hospitalization. GAM analysis revealed a nonlinear and U-shaped relationship between SpO 2 levels and in-hospital all-cause mortality among sepsis patients during hospitalization. Multivariable Logistic regression analysis further confirmed that patients with SpO 2 levels between 0.96 and 0.98 during hospitalization had a decreased mortality compared to those with SpO 2 < 0.96 [hypoxia group; odds ratio ( OR) = 2.659, 95% confidence interval (95% CI) was 2.190-3.229, P < 0.001] and SpO 2 > 0.98 (hyperoxia group; OR = 1.594, 95% CI was 1.337-1.900, P < 0.001). Kaplan-Meier survival curve showed that patients with SpO 2 between 0.96 and 0.98 during hospitalization had a higher probability of survival than those patient with SpO 2 < 0.96 and SpO 2 > 0.98 (Log-Rank test: χ2 = 113.400, P < 0.001). Sensitivity analyses demonstrated that, with the exception of subgroups with smaller sample sizes, across the strata of age, gender, body mass index (BMI), admission type, race, heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure, respiratory rate, body temperature, myocardial infarction, congestive heart failure, cerebrovascular disease, chronic liver disease, diabetes mellitus, sequential organ failure assessment (SOFA), simplified acute physiology score Ⅱ (SAPSⅡ), systemic inflammatory response syndrome score (SIRS), and Glasgow coma score (GCS), the mortality of patients with SpO 2 between 0.96 and 0.98 was significantly lower than those of patients with SpO 2 < 0.96 and SpO 2 > 0.98. Conclusions:During hospitalization, the level of SpO 2 among sepsis patients exhibits a U-shaped relationship with in-hospital all-cause mortality, indicating that heightened and diminished oxygen levels are both associated with increased mortality risk. The optimal SpO 2 range is determined to be between 0.96 and 0.98.

Objective:To analyze types of mucosal candidiasis and drug resistance of relevant pathogens in a dermatology outpatient clinic in Taiyuan.Methods:Clinical data were collected from 172 patients with mucosal candidiasis, who had positive fungal culture results, in the dermatology outpatient clinic of Shanxi Bethune Hospital from 2019 to 2020. Pathogens were identified by a molecular biological approach, and in vitro drug sensitivity test was performed. Results:Among the 172 patients with mucosal candidiasis, 142 (82.6%) had vulvovaginal candidiasis, 24 (14.0%) had candidal balanoposthitis, and 6 (3.5%) had oral candidiasis; 3 patients were aged ≤ 18 years, 155 were aged 19 - 59 years, and 14 were aged ≥ 60 years, and the proportion of patients with vulvovaginal candidiasis significantly differed among the above 3 age groups (2/3, 134/155[86.45%], 6/14, respectively; χ2 = 14.29, P < 0.05) . Molecular biological identification showed that all the 172 isolated strains belonged to the genus Candida, including 165 strains of Candida albicans (95.9%) , 5 strains of Candida glabrata (2.9%) , and 2 strains of Candida parapsilosis (1.2%) ; the sensitivity to common antifungal agents including flucytosine, amphotericin B, fluconazole, itraconazole and voriconazole was 95.9%, 100.0%, 62.2%, 47.1% and 56.4%, respectively. Conclusion:In the dermatology outpatient clinic of Shanxi Bethune Hospital, vulvovaginal candidiasis was the most common type of mucosal candidiasis, and the main pathogen was Candida albicans; the Candida isolates showed high sensitivity to flucytosine and amphotericin B.

Objective:To investigate the value of monitoring on serum silent information regulator-related enzyme 3 (SIRT3), glucagon-like peptide-1 (GLP-1) and angiopoietin-like protein 4 (ANGPTL4) in patients with acute ischemic stroke (AIS).Methods:Eighty patients with AIS who treatment in Qiongzhong Li and Miao Autonomous County People′s Hospital from May 2019 to April 2022 were selected retrospectively as the observation group, and 60 healthy volunteers who underwent physical examination during the same period were selected as the normal control group. The levels of serum SIRT3, GLP-1, and ANGPTL4 between the two groups were compared. The neurological deficit degree of AIS patients was evaluated by National Institutes of Health Stroke Scale(NIHSS) and the correlation of SIRT3, GLP-1 and ANGPTL4 with neurological deficit degree were analyzed. The levels of serum SIRT3, GLP-1 and ANGPTL4 before and after treatment and their difference value were compared between different clinical outcome of AIS patients, the risk factors for poor clinical outcome of AIS patients were analyzed by Logistic regression analysis, the value of prediction was analyzed by receiver operating characteristic (ROC) curve.Results:The level of serum GLP-1 in the observation group was lower than that in the normal control group: (50.37 ± 5.69) nmol/L vs. (34.89 ± 4.26) nmol/L; and the levels of serum SIRT3 and ANGPTL4 in the observation group were higher than those in the normal control group: (50.37 ± 5.69) ng/L vs. (34.89 ± 4.26) ng/L, (15.07 ± 3.12) μg/L vs. (11.15 ± 2.63) μg/L, there were statistical differences ( P<0.05). The results of correlation analysis showed that the levels of serum SIRT3 and ANGPTL4 were positively correlated with the degree of neurological impairment in AIS patients( r = 0.631, 0.776, P<0.05), and the level of serum GLP-1 was negatively correlated with the degree of neurological impairment in AIS patients ( r = - 0.693, P<0.05). After treatment, 66 patients obtained good clinical outcome, the good outcome rate was 82.50%(66/80). The levels of serum SIRT3 and ANGPTL4 in the poor clinical outcome patients were higher than those in the good clinical outcome patients: (41.33 ± 4.74) ng/L vs. (37.82 ± 4.05) ng/L, (12.98 ± 2.17) μg/L vs. (11.69 ± 2.06) μg/L; the level of serum GLP-1 in the poor clinical outcome patients was lower than that in the good clinical outcome patients: (592.33 ± 98.44) nmol/L vs. (709.41 ± 125.31) nmol/L; the difference value of SIRT3, GLP-1 and ANGPTL4 before and after treatment in the poor clinical outcome patients were lower than those in the good clinical outcome patients: (10.22 ± 2.05) ng/L vs. (12.31 ± 2.94) ng/L, (268.21 ± 70.12) nmol/L vs. (379.92 ± 85.33) nmol/L, (2.18 ± 0.65) μg/L vs. (3.36 ± 0.94) μg/L, there were statistical differences ( P<0.05). The results of Logistic regression analysis showed that differences value of SIRT3, GLP-1 and ANGPTL4 before and after treatment were all independent influencing factors of poor clinical outcome in patients with AIS ( P<0.05). The results of ROC curve analysis showed that the area under the curve (AUC) of differences value of SIRT3, GLP-1 and ANGPTL4 before and after treatment in predicting poor clinical outcome were 0.701, 0.758 and 0.844, respectively, and had certain predictive value, the AUC of joint evaluation was the largest (0.912). Conclusions:The levels of serum SIRT3 and ANGPTL4 in patients with AIS are increased, and the level of serum GLP-1 is decreased, and they are related to the degree of neurological deficit. Clinical monitoring of their level changes is helpful for clinical evaluation of the clinical outcome of patients with AIS.

Objective:To explore the predictive value of systemic immune inflammation index (SII) for the risk of hospital death in critically ill patients.Methods:The basic information and clinical data of critically ill patients were extracted from the Medical Information Mart for Intensive Care database-Ⅳ (MIMIC-IV) database, including demographic data, vital signs, blood routine, Logistic organ dysfunction score (Lods), Oxford acute severity of illness score (Oasis), simplified acute physiology score (Saps-Ⅱ), acute physiology score Ⅲ (APS-Ⅲ), sequential organ failure score (SOFA) and outcome. The main outcome was hospital death, and the secondary outcomes were length of hospital stay, continuous renal replacement therapy (CRRT), invasive ventilation and 1-year mortality. Patients were divided into two groups according to in-hospital death, and the differences between the groups were compared. According to the SII tripartite for inter-group comparison, the patients were further divided into three groups for comparison, and Logistic regression model was used to analyze the odd ratio ( OR) of the three groups. Results:A total of 32 450 critically ill patients were included in the study, of which 3765 died in hospital, with a mortality rate of 11.6%. ① Compared with the survival group, the SII in the death group were significantly higher ( P < 0.05). ② The mortality for the SII tripartite grouping (<817; 817~2 151; >2 151) were 8.4%, 10.2% and 16.3%, respectively, and the differences between groups were statistically significant. ③ Further, Logistic regression model analysis showed that the risk of death increased gradually with the increase of groups (the first group was the reference group, OR of the second group was 1.38, 95% CI 1.24-1.54, and OR of the third group was 2.03, 95% CI 1.83-2.24 ( P < 0.05). Conclusions:SII has a certain value in predicting hospital death in critically ill patients. It is easy to obtain and can be used for risk stratification of critically ill patients.

Objective:To explore the causes and summarize the treatment experience for clinically relevant delayed gastric emptying(DGE) after laparoscopic pancreaticoduodenectomy(LPD).Methods:The clinical data of 1 000 patients who underwent LPD in the Department of Liver Transplantation and Hepatobiliary Surgery,Shandong Provincial Hospital Affiliated to Shandong First Medical University between March 2017 and September 2022 was retrospectively collected. There were 640 males and 360 females,with an age of (60.1±11.4)years(range: 13 to 93 years),and 590 patients were older than 60 years. Depending on the severity of DGE,patients were divided into a clinically relevant DGE group and a 0/A grade DGE group. The comparison between the two groups was performed by the χ2 test,Fisher′s exact probability method, t test or the rank sum test,and the effects of various treatment strategies for clinically relevant DGE were evaluated. Results:LPD was conducted successfully in all 1 000 patients,with a surgical time of (344.8±103.6)minutes(range:160 to 450 minutes) and intraoperative blood loss ( M(IQR)) of 100 (150) ml(range:50 to 1 000 ml). A total of 74 patients(7.4%) developed clinically relevant DGE. Compared to those in the 0/A grade DGE group,patients in the clinically relevant DGE group had a higher preoperative body mass index of ((24.9±3.5)kg/m 2vs. (23.9±3.3)kg/m 2, t=-2.419, P=0.016),more postoperative bile leakage(51.4%(38/74) vs. 10.8%(100/926)),pancreatic fistula(59.5%(44/74) vs. 22.9%(212/926)),abdominal infection(74.3%(55/74) vs.14.6%(135/926)),and abdominal bleeding(43.2%(32/74) vs. 11.3%(105/926))(all P<0.05). Among these patients,10 cases(13.5%) received enteral nutrition treatment,22 cases(29.7%) received parenteral nutrition treatment,and 42 cases(56.8%) received a combination of enteral and parenteral nutrition treatment. The time for patients to return to a normal diet was 21(14)days (range: 8 to 85 days). Compared to those who received only enteral(23.5(27.0)days) or parenteral nutrition treatment(15.5(11.0)days),patients who received a combination of enteral and parenteral nutrition treatment(25.5(31.0)days) had a longer time to return to a normal diet ( Z=20.019, P<0.01). Among the 60 patients who developed secondary DGE,48 cases(80.0%) received ultrasound-guided puncture and drainage treatment,while 12 cases(20.0%) only received anti-infection treatment. The patients in the non-puncture drainage group had a longer time to return to a normal diet than those in the puncture drainage group (26.5(12.5)days vs. 20.0(11.0)days, Z=-2.369, P=0.018). Conclusions:Patients with clinically relevant DGE after LPD had a higher proportion of postoperative complications such as pancreatic fistula,biliary fistula and abdominal infection. A combination of enteral and parenteral nutrition treatment is needed for patients with a long-term course of DGE."Smooth" drainage and ani-infectious therapy could contribute to the recovery of DGE.
