AIM:To observe the changes of Th17 related cytokines in tears of conjunctivochalasis(CCH)patients with liver-kidney yin deficiency treated with traditional Chinese medicine Qi Jing Mingmu decoction combined with artificial tears.METHODS:A total of 56 CCH patients(56 eyes)with liver-kidney yin deficiency of grade Ⅱ to Ⅲ were collected and randomly divided into treatment group(treated with Qi Jing Mingmu decoction combined with artificial tears)of 26 cases(26 eyes)and control group(treated with pure artificial tears)of 30 cases(30 eyes). The treatment course was 1 mo, and international ocular surface disease index(OSDI), tear film break-up time(BUT), tear meniscus height(TMH)and conjunctival congestion index of the patients were observed before and after treatment. The patients' tears were collected before and after treatment, and Th17 related cytokines in tears were detected using flow cytometry immunofluorescence luminescence method.RESULTS:After treatment, the OSDI, BUT and conjunctival congestion index of CCH patients in the treatment group and control group were significantly improved(all P<0.01). After treatment, the TMH of CCH patients in the treatment group was significantly reduced(P<0.01), while there was no statistically significant difference in TMH of the control group before and after treatment(P=0.41). After treatment, the levels of Th17 related cytokines IL-17A, IL-22, IFN-γ, IL-17F, and IL-1β in tears of CCH patients in the treatment group were significantly reduced after treatment(all P<0.01), and the changes in the treatment group were more significant(all P<0.05). There was no significant difference in the control group before and after treatment(all P>0.05). After treatment, the levels of IL-6 and TNF-α in the tears of both groups of CCH patients decreased compared to those before treatment(both P<0.05), but the changes in the treatment group were more significant(both P<0.01).CONCLUSION:Qi Jing Mingmu decoction combined with artificial tears can effectively improve the ocular surface microenvironment, enhance tear film stability, and inhibit ocular surface inflammation in CCH patients with liver-kidney yin deficiency. This may be related to its reduction in the secretion of Th17 related cytokines in tears.

BACKGROUND: Delayed platelet engraftment is a common complication after umbilical cord blood transplantation (UCBT), and there is no standard therapy. Avatrombopag (AVA) is a second-generation thrombopoietin (TPO) receptor agonist (TPO-RA) that has shown efficacy in immune thrombocytopenia (ITP). However, few reports have focused on its efficacy in patients diagnosed with thrombocytopenia after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: We conducted a retrospective study at the First Affiliated Hospital of the University of Science and Technology of China to evaluate the efficacy of AVA as a first-line TPO-RA in 65 patients after UCBT; these patients were compared with 118 historical controls. Response rates, platelet counts, megakaryocyte counts in bone marrow, bleeding events, adverse events and survival rates were evaluated in this study. Platelet reconstitution differences were compared between different medication groups. Multivariable analysis was used to explore the independent beneficial factors for platelet implantation. RESULTS: Fifty-two patients were given AVA within 30 days post-UCBT, and the treatment was continued for more than 7 days to promote platelet engraftment (AVA group); the other 13 patients were given AVA for secondary failure of platelet recovery (SFPR group). The median time to platelet engraftment was shorter in the AVA group than in the historical control group (32.5 days vs . 38.0 days, Z  = 2.095, P  = 0.036). Among the 52 patients in the AVA group, 46 achieved an overall response (OR) (88.5%), and the cumulative incidence of OR was 91.9%. Patients treated with AVA only had a greater 60-day cumulative incidence of platelet engraftment than patients treated with recombinant human thrombopoietin (rhTPO) only or rhTPO combined with AVA (95.2% vs . 84.5% vs . 80.6%, P  <0.001). Patients suffering from SFPR had a slightly better cumulative incidence of OR (100%, P  = 0.104). Patients who initiated AVA treatment within 14 days post-UCBT had a better 60-day cumulative incidence of platelet engraftment than did those who received AVA after 14 days post-UCBT (96.6% vs . 73.9%, P  = 0.003). CONCLUSION Compared with those in the historical control group, our results indicate that AVA could effectively promote platelet engraftment and recovery after UCBT, especially when used in the early period (≤14 days post-UCBT).

The chemical components of Carthami Flos were investigated by using macroporous resin, silica gel column chromatography, reversed-phase octadecylsilane(ODS) column chromatography, Sephadex LH-20, and semi-preparative high-performance liquid chromatography(HPLC). The planar structures of the compounds were established based on their physicochemical properties and ultraviolet-visible(UV-Vis), infrared(IR), high-resolution electrospray ionization mass spectrometry(HR-ESI-MS), and nuclear magnetic resonance(NMR) spectroscopic technology. The absolute configurations were determined by comparing the calculated and experimental electronic circular dichroism(ECD). Six flavonoid C-glycosides were isolated from the 30% ethanol elution fraction of macroporous resin obtained from the 95% ethanol extract of Carthami Flos, and identified as saffloquinoside F(1), 5-hydroxysaffloneoside(2), iso-5-hydroxysaffloneoside(3), isosafflomin C(4), safflomin C(5), and vicenin 2(6). Among these, the compounds 1 to 3 were new chalcone C-glycosides. The compounds 1, 2, 4, and 5 could significantly increase the viability of H9c2 cardiomyocytes damaged by oxygen-glucose deprivation/reoxygenation(OGD/R) at a concentration of 50 μmol·L~(-1), showing their good cardioprotective activity.

Objective:To explore the predictive value of the neutrophil-to-lymphocyte ratio (NLR) combined with blood glucose at admission for a positive blood culture for sepsis.Methods:A single-center retrospective cohort study was conducted. According to the 2016 American Society of Critical Care/European Society of Critical Care Medicine (SCCM/ESICM) and diagnostic criteria for sepsis and septic shock-3.0 (sepsis-3.0), patients with sepsis were admitted to the Emergency Department of Fujian Medical University Union Hospital for more than 24 h from January 2019 to December 2021 were enrolled. Age, gender, sequential organ failure assessment, source of infection, NLR, and blood culture results were recorded. Based on the blood culture results, patients were divided into a blood culture positive group (Gram-positive group, Gram-negative group) and blood culture negative group, and the differences between the groups were compared. The risk factors for a positive blood culture were analyzed using multivariate logistic regression. A receiver operating characteristic analysis was performed for the NLR combined with the blood glucose measurement.Results:A total of 265 patients with sepsis were included, of which 62 were positive in blood culture (15 Gram-positive patients, 37 Gram-negative patients and 10 fungal patients). The positive rate of blood culture was 23.4%. The number of patients with history of diabetes, neutrophil count, procalcitonin, blood glucose, and NLR in the positive blood culture group were significantly higher than those in the negative blood culture group (all P<0.001). Multivariate logistic regression analysis revealed that random admission blood glucose ( OR=1.116, 95% CI: 1.051~1.186, P<0.001) and NLR ( OR=1.039, 95% CI: 1.015~1.064, P=0.001) were independent risk factors for blood culture positivity in sepsis patients. For patients with blood culture positive, and with Gram-negative bacterial bloodstream infections, the AUC of the NLR combined with the admission blood glucose level was 0.819 (95% CI: 0.761-0.877, P<0.001) and 0.871 (95% CI: 0.813-0.928, P<0.001), respectively. Conclusions:The combination of NLR and random admission blood glucose could provide a good predictive value for blood culture positive and gram-negative bacterial bloodstream infections in sepsis patients.

A 31P-quantitative nuclear magnetic resonance(qNMR)method was established for simultaneous determination of sodium α-glycerophosphate,sodium β-glycerophosphate and phosphoric acid in concentrated divitamins and sodium phosphate syrup.The qNMR experimental conditions were optimized,including hexamethylphosphoramide as internal standard,20%deuterium oxide solution as solvent,zgig pulse sequence,delay time of 30 s,and scan number of 64.The 31P-NMR peaks atδ29.80 of hexamethylphosphoramide,δ0.69 of sodiumα-glycerophosphate,δ0.17 of sodiumβ-glycerophosphate andδ0.03 of phosphoric acid were chosen as the quantitative peaks(pH of the test solution was around 4.8).Method validation was performed in terms of precision(Relative standard deviation less than 0.6%),linearity(Correlative coefficient greater than 0.999),limit of detection(23.58 μg/mL for sodium glycerophosphate and 11.61 μg/mL for phosphoric acid)and limit of quantitation(78.60 μg/mL for sodium glycerophosphate and 38.70 μg/mL for phosphoric acid).The recoveries were 99.8%?103.2%,and relative standard deviations were 0.41%?1.98%.The results showed that the reliability of 31P-qNMR method were suitable for its intended use.Seven batches of concentrated divitamins and sodium phosphate syrups were tested by the established method,of which the total phosphorus content was consistent with that of colorimetry method,but the content of sodium glycerophosphate(Sum ofαtype andβtype)was relatively low,about 82%of the labeled amount.The content of phosphoric acid was high.This method simplified sample pretreatment and had high specificity,and was more suitable for determination and quality control of concentrated divitamins and sodium phosphate syrup.

Parkinson's disease (PD) is a chronic neurodegenerative disease. At present, levodopa and other drugs are mainly used for dopamine supplementation therapy. However, the absorption of levodopa in the gastrointestinal tract is unstable and its half-life is short, and long-term use of levodopa will lead to the end-of-dose deterioration, dyskinesia, the "ON-OFF" phenomenon and other symptoms. Therefore, new preparations need to be developed to improve drug efficacy, reduce side effects or improve compliance of patients. Based on the above clinical needs, this review briefly introduced the preparation modification strategies for the treatment of PD through case analysis, in order to provide references for the research and development of related preparations.

Objective: To investigate the level of mental heath literacy and influencing factors among grassroots mental heath workers in Xinjiang Uygur Autonomous Region, so as to provide insights into relevant intervention measurements. Methods: Full-time (part-time) grassroots mental heath workers were sampled from grassroots healthcare institution (community health service centers and township health institutes) in Xinjiang Uygur Autonomous Region. Participants' demographics and achievements of the target for mental heath literacy were collected through self-designed questionnaires and the Mental Health Literacy Questionnaire, and factors affecting the achievements of the target for mental heath literacy were identified using a multivariable logistic regression model. Results: A total of 3 382 respondents were recovered, including 771 males (22.80%) and 2 611 females (77.20%), and had a mean age of (35.59±9.21) years. There were 491 respondents that met the target of the mental health literacy (14.52%). Multivariable logistic regression analysis showed that grassroots mental heath workers who were Han Ethnicity (OR=2.735, 95%CI: 2.166-3.454), had high levels of education (college, OR=1.722, 95%CI: 1.299-2.283; bachelor degree and above, OR=2.681, 95%CI: 1.966-3.656), worked at community health service centers (OR=1.435, 95%CI: 1.142-1.803), physician (OR=1.877, 95%CI: 1.239-2.843) and engaged in mental health prevention and treatment for 2 to <5 years (OR=1.388, 95%CI: 1.059-1.818) were more likely to meet the target of the mental health literacy. Conclusion The proportion of achieving the target for mental health literacy is low among grassroots mental health care workers in Xinjiang Uygur Autonomous Region, and ethnicity, educational level, organization category, occupation and service length of mental health prevention and treatment are the influencing factors.

Objective To investigate the clinical value of prophylactic high-flow nasal cannula oxygen therapy (HFNC) in reducing postoperative pulmonary complication (PPC) in elderly patients with non-small cell lung cancer (NSCLC). Methods The clinical data of elderly patients (over 60 years) with NSCLC who underwent video-assisted thoracoscopic lobectomy or segmental resection at the Department of Thoracic Surgery, Fujian Provincial Hospital from January 2021 to March 2022 were retrospectively analyzed. According to whether receiving HFNC after surgery, they were divided into a conventional oxygen therapy (CO) group and a HFNC group. The CO group were matched with the HFNC group by the propensity score matching method at a ratio of 1 : 1. We compared PPC incidence, white blood cell (WBC) count, procalcitonin and C-reactive protein on postoperative day (POD) 1, 3 and 5 and postoperative hospital stay between the two groups. Results A total of 343 patients (165 males, 178 females, average age of 67.25±4.79 years) were enrolled, with 53 (15.45%) receiving HFNC. Before matching, there were statistical differences in gender, rate of combined chronic obstructive pulmonary disease, pathology type and TNM stage between the two groups (all P<0.05). There were 42 patients successfully matched in each of the two groups, with no statistical difference in baseline characteristics (P>0.05). After propensity score matching, the results showed that the PPC incidence in the HFNC group was lower than that in the CO group (23.81% vs. 45.23%, P=0.039). WBC count on POD 3 and 5 and procalcitonin level on POD 3 were less or lower in the HFNC group than those in the CO group [ (8.92±2.91)×109/L vs. (10.62±2.67)×109/L; (7.68±1.58)×109/L vs. (8.86±1.76)×109/L; 0.26 (0.25, 0.44) μg/L vs. 0.31 (0.25, 0.86) μg/L; all P<0.05]. There was no statistical difference in the other inflammatory indexes or the postoperative hospital stay between the two groups (P>0.05). Conclusion Prophylactic HFNC can reduce the PPC incidence and postoperative inflammatory indexes in elderly patients with NSCLC, but does not shorten the postoperative hospital stay.
