OBJECTIVE To build a Tibetan-language medication service platform based on “internet+” and evaluate its effect on improving medication compliance and safety of Tibetan patients with chronic disease. METHODS Medication guidance contents of commonly used drugs in the outpatient department were summarized， translated and recorded in Tibetan-language or video to form a “text-audio-video” multi-dimensional “internet+ ” Tibetan-language medication service platform. A total of 387 Tibetan outpatients with chronic disease in our hospital after the implementation of “internet+” Tibetan-language medication service platform （from January 2024 to June 2024） in our hospital were selected as the intervention group， and 387 Tibetan outpatients before the implementation （from January 2023 to June 2023） were selected as the control group. Patients in the control group received conventional window-based Chinese-language medication services， while patients in the intervention group received both conventional window-based Chinese-language medication service and “internet+ ” Tibetan-language medication service. The medication compliance of patients was evaluated using the 12-item Medication Compliance Scale. A six-level causality assessment was conducted as the principles for analyzing adverse drug reactions （ADR） set by the National Center for ADR Monitoring. Additionally， statistics were compiled on the occurrence of ADR that were assessed as “definite”“probable” or “possible” in the causality assessment. RESULTS The proportion （31.0%） of patients with good medication compliance and compliance scores [39.0 （37.0，42.0）] of patients in the intervention group were significantly better than control group [7.0%， 21.0（19.0， 23.0）]（ P＜0.05）. There were no statistically significant differences in the incidence of various types of ADR or the overall incidence between the two groups （P＞0.05）. CONCLUSIONS The “internet+” Tibetan-language medication service platform is constructed successfully； the service can effectively improve the medication compliance of Tibetan-language patients， but its effect on improving the medication safety of patients is limited.

Objective To explore the clinical efficacy of modified Xuefu Zhuyu Decoction combined with acupoint application for the treatment of patients with stable angina pectoris in coronary heart disease(SAP-CHD),and to evaluate its clinical value for the treatment of SAP-CHD.Methods A total of 92 patients with SAP-CHD of heart-blood stasis and obstruction complicated with qi deficiency type were randomly divided into control group and observation group,with 46 cases in each group.The control group was treated with conventional western medicine alone,and the observation group was treated with modified Xuefu Zhuyu Decoction combined with acupoint application on the basis of treatment for the control group.The two groups were treated for 4 weeks.The changes of traditional Chinese medicine(TCM)syndrome scores,Pittsburgh Sleep Quality Index(PSQI)scores,cardiac function indicators of left ventricular ejection fraction(LVEF),left ventricular end-systolic diameter(LVESD)and left ventricular end-diastolic diameter(LVEDD),and frequency and duration of angina pectoris in the two groups before and after treatment were observed.After treatment,the TCM syndrome efficacy in the two groups was evaluated.Results(1)After 4 weeks of treatment,the total effective rate of TCM syndrome efficacy in the observation group was 91.30％(42/46),and that of the control group was 76.09％(35/46).The intergroup comparison(tested by chi-square test)showed that the TCM syndrome efficacy in the observation group was significantly superior to that in the control group(P＜0.05).(2)After treatment,the scores of TCM syndromes in the two groups were decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was more significant than that in the control group(P＜0.05).(3)After treatment,the PSQI scores of sleep quality in the two groups were lower than those before treatment(P＜0.05),and the decrease of PSQI score in the observation group was significantly superior to that in the control group after treatment(P＜0.05).(4)In terms of cardiac function,LVEF in the two groups after treatment was higher than that before treatment(P＜0.05),LVESD and LVEDD were lower than those before treatment(P＜0.05).The increase of LVEF and the decrease of LVESD and LVEDD in the observation group were significantly superior to those in the control group after treatment(P＜0.05).(5)After treatment,the frequency and duration of angina pectoris in the two groups were improved compared with those before treatment(P＜0.05),and the improvement in the frequency and duration of angina pectoris in the observation group was superior to that in the control group(P＜0.05).Conclusion On the basis of conventional western medicine treatment,modified Xuefu Zhuyu Decoction combined with acupoint application exerts certain clinical effect for the treatment of patients with stable angina pectoris in coronary heart disease.The combined therapy is effective on improving the cardiac function and sleep quality of the patients,reducing the attack of angina pectoris and shortening the duration of angina pectoris,with stronger efficacy than that of conventional western medicine alone.

Objective:To analyze the genotype distribution and hematological characteristics of children with thalassemia in Chongqing.Methods:A total of 207 children with thalassemia admitted to Chongqing University Three Gorges Hospital from January 2021 to October 2022 were selected as the research objects.The genotype distribution and hematological characteristics were retrospectively analyzed.Results:207 cases of thalassemia were confirmed from 482 samples by gene detection,the detection rate was 42.95％,α-thalassemia accounted for 17.63％(85/482),β-thalassemia accounted for 24.27％(117/482),and compound αβ thalassemia accounted for 1.04％(5/482).A total of 5 gene mutation types of α-thalassaemia were detected in this study,which constituted 6 genotypes,αα/-SEA was the most common one,followed by αα/-α7.A total of 8 gene mutation types of β-thalassemia were detected,which constituted 9 genotypes,the top three were CD17/N,CD654/N and CD41-42/N.The highest detection rate was found in the patients aged 0-3 years(57％),and the degree of anemia was mainly mild(88.41％).97.58％of the patients were MCV＜80 fl,98.55％were MCH＜28 pg,60.87％were MCHC＜320 g/L,and 71.50％were RDW-SD＜37％.The MCV and MCH of β-thalassemia group were lower than that of α-thalassemia group,and the MCHC was higher than that of α-thalassemia group(P＜0.05),but RDW-SD was not significantly different between the two groups(P＞0.05).There were no significant differences in MCV,MCH,MCHC and RDW-SD between β+/βN and β0/βN groups(P＞0.05).The MCV and RDW-SD of--/αα thalassemia group were lower than that in-α/αα thalassemia group,the differences were statistically significant(P＜0.05),but MCH and MCHC were not significantly different between the two groups(P＞0.05).Conclusion:The genotypes of children with thalassemia in Chongqing are diverse and heterogeneous,and the majority of them are mild anemia.There are differences in haematological indexes among different genotypes of thalassemia.

Objective To explore the potential influencing factors of post-operative healthcare-associated infection(HAI)in colorectal cancer patients,as well as the mediating effect relationship between the influencing factors and the diagnosis-intervention packet(DIP)payment differentials.Methods Medical data of patients who underwent colorectal cancer surgery in a tertiary first-class cancer hospital in Guangzhou were retrospectively analyzed.According to HAI status,patients were divided into infection group and non-infection group.Baseline demographic information and differences in DIP payment differentials between two groups of patients were compared by rank sum test or chi-square test.The influence of each potential factor on the occurrence of HAI was analyzed by logistic re-gression.Mediating analysis was preformed by bootstrap method,and mediating effect of HAI and total hospitaliza-tion days on DIP payment differentials was evaluated.Results A total of 350 patients were included in analysis,50 were in the infection group and 300 in the non-infection group.The incidence of HAI was 14.29％.Logistic regres-sion analysis result showed that risk of HAI in patients with central venous catheterization ≥10.00 days was 13.558 times higher than that＜10.00 days(P＜0.001);risk of HAI in patients with urinary catheterization ≥3.00 days was 2.388 times higher than that＜3.00 days(P=0.022).There were all statistically significant differences in DIP payment differentials among patients with different ages,prognostic nutritional index(PNI),HAI status,total length of hospitalization stay,duration of surgery,central venous catheterization days,and catheterization days(all P＜0.05).The mediating analysis results showed that the occurrence of HAI resulted a change in DIP payment di-fferentials by affecting the total number of hospitalization days.The mediating effect value of total hospitalization days was 0.038,accounting for 35.68％of the total effect.Conclusion Medical institutions should pay attention to HAI resulting from prolonged central venous and urinary catheterization in patients underwent surgery for colorectal cancer,reducing the total length of hospital stay,thus reducing the overruns associated with the increased DIP pay-ment differentials.

Objective: To investigate the influence of reactive oxygen species (ROS) responsive self-assembled nanomicelle loaded with pyroptosis inhibitor on full-thickness skin defects in diabetic rats. Methods: Experimental research methods were employed. A nucleotide-binding oligomerization domain (NOD) 1/2 inhibitor (NOD-IN-1) was encapsulated with nanomicelle polyethylene glycol-block-polypropylene sulfide (PEG-b-PPS), and the resulting product was called PEPS@NOD-IN-1. The morphology and hydration particle size of PEG-b-PPS and PEPS@NOD-IN-1 were observed by transmission electron microscope and particle size analyzer, respectively, and the encapsulation rate and drug loading rate of PEPS@NOD-IN-1 to NOD-IN-1 and the cumulative release rate of NOD-IN-1 by PEPS@NOD-IN-1 in phosphate buffer solution (PBS) alone and hydrogen peroxide-containing PBS within 40 h were measured and calculated by microplate reader, and the sample number was 3. Twenty-four male Sprague-Dawley rats aged 6-7 weeks were injected with streptozotocin to induce type 1 diabetes mellitus. Six full-thickness skin defect wounds were made on the back of each rat. The injured rats were divided into PBS group, NOD-IN-1 group, PEG-b-PPS group, and PEPS@NOD-IN-1 group with corresponding treatment according to the random number table, with 6 rats in each group. The wound healing was observed on post injury day (PID) 3, 7, and 12, and the wound healing rate was calculated. The ROS levels in wound tissue were detected by immunofluorescence method on PID 3. On PID 7, the granulation tissue thickness in wound was assessed by hematoxylin-eosin staining, the mRNA expressions of NOD1 and NOD2 were detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction, and the protein expressions of NOD1, NOD2, and GSDMD-N terminals were detected by Western blotting. Six wounds from different rats in each group were taken for detection of the above indicators. Wound tissue (3 samples per group) was taken from rats in PBS group and PEPS@NOD-IN-1 group on PID 7, and transcriptome sequencing was performed using high-throughput sequencing technology platform. Differentially expressed genes (DEGs) significantly down-regulated in PEPS@NOD-IN-1 group as compared with PBS group were screened, and the enrichment analysis of Kyoto Encyclopedia of Genes and Genomes (KEGG) was performed. The DEG heatmap of the NOD-like receptor pathway, a pyroptosis-related pathway, was made. Protein-protein interaction (PPI) analysis of DEGs in heatmap was performed through the STRING database to screen key genes of PEPS@NOD-IN-1 regulating the NOD-like receptor pathway. Data were statistically analyzed with analysis of variance for repeated measurement, one-way analysis of variance, and Tukey test. Results: PEG-b-PPS and PEPS@NOD-IN-1 were in spherical structures of uniform size, with hydration particle sizes of (134.2±3.3) and (143.1±2.3) nm, respectively. The encapsulation rate of PEPS@NOD-IN-1 to NOD-IN-1 was (60±5)%, and the drug loading rate was (15±3)%. The release of NOD-IN-1 from PEPS@NOD-IN-1 in PBS alone was slow, and the cumulative release rate at 40 h was only (12.4±2.3)%. The release of NOD-IN-1 from PEPS@NOD-IN-1 in hydrogen peroxide-containing PBS within 10 h was very rapid, and the cumulative release rate at 10 h reached (90.1±3.6)%. On PID 3 and 7, the wounds of rats in the four groups were gradually healed, and the healing in PEPS@NOD-IN-1 group was better than that in the other three groups. On PID 12, the wound scab area in PBS group was large, the wound epithelialization in NOD-IN-1 group and PEG-b-PPS group was obvious, and the wound in PEPS@NOD-IN-1 group was close to complete epithelialization. Compared with those in PBS group, NOD-IN-1 group, and PEG-b-PPS group, the wound healing rates on PID 7 and 12 in PEPS@NOD-IN-1 group were significantly increased (P<0.05), the level of ROS in wound tissue on PID 3 was significantly decreased (P<0.05), the thickness of granulation tissue in wound on PID 7 was significantly thickened (P<0.05), and the mRNA expressions of NOD1 and NOD2 and the protein expressions of NOD1, NOD2, and GSDMD-N terminals in wound tissue on PID 7 were significantly decreased (P<0.05). KEGG pathway analysis showed that DEGs significantly down-regulated in PEPS@NOD-IN-1 group as compared with PBS group were significantly enriched in NOD-like receptors, hypoxia-inducible factors, mitogen-activated protein kinases, and tumor necrosis factor (TNF) pathways. In the DEG heatmap of NOD-like receptor pathway, the genes regulating pyroptosis mainly involved NOD1, NOD2, NOD-like receptor thermoprotein domain-related protein 3, Jun, signal transduction and transcriptional activator 1 (STAT1), TNF-α-induced protein 3. The PPI results showed that NOD1, NOD2, and STAT1 were the key genes of PEPS@NOD-IN-1 regulating the NOD-like receptor pathway. Conclusions: PEPS@NOD-IN-1 can down-regulate the level of local ROS in wounds and the expression of NOD1, NOD2, and GSDMD-N terminals, the key regulators of pyroptosis, thereby promoting the repair of full-thickness skin defect wounds in diabetic rats. PEPS@NOD-IN-1 can also significantly down-regulate the pyroptosis, inflammation, and hypoxia-related pathways of wounds, and regulate NOD-like receptor pathways by down-regulating key genes NOD1, NOD2, and STAT1.

Objective:To investigate the relationship between the levels of serum cytokines and chemokines and the prognosis of patients with acute B-ALL after receiving chimeric antigen receptor (CAR)-T cell immunotherapy and acute graft-versus-host disease (aGVHD) in patients after bridging allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:According to the case-control principle, Forty-two patients with B-ALL who received CD19-CAR-T cell immunotherapy bridged to allo-HSCT at Heibei Yanda Ludaopei Hospital from September 18, 2019 to May 9, 2022 were enrolled. Mann-Whitney U test was used to compare the changes of aGVHD-related cytokines and chemokine levels between CAR-T cell immunotherapy and bridging transplantation in different patients at the same time. Their plasma levels of cytokines and chemokines related to aGVHD were monitored at the day before CAR-T therapy and after CAR-T treatment at day 4, 7,14,21,28. The receiver operating characteristic curve was drawn to evaluate the predictive value of cytokines and chemokines in predicting the occurrence and the death of aGVHD patients. Kaplan-Meier method and Log-rank tests were used for Overall survival (OS) analysis. Results:Twenty-four of total 42 patients had aGVHD, of which 11 patients died and 31 patients survived. There was no significant difference in cytokines and chemokines between the aGVHD group and the non-aGVHD group on the day before CAR-T cell treatment. According to statistical analysis, the serum Elafin levels of aGVHD group was higher than that of non-aGVHD group at the 21st day [4 482 (2 811, 6 061) ng/L vs 2 466 (1 948, 3 375) ng/L, Z=3.145, P=0.001] and the 28st day [4 391 (2 808, 5594) ng/L vs 2 463 (1 658, 2 830) ng/L, Z=2.038, P=0.048] separately. At the 14th day, serum cytokines and chemokines levels between the two group were as follows,MIP-1 α [21.02 (12.36, 30.35) ng/L vs 5.56 (3.64, 10.79) ng/L], sCD25 [422.47 (257.99, 1 233.78) IU/ml vs 216.11 (133.75,457.39) IU/ml], Elafin [4 101 (2 393, 5 006) ng/L vs 2 155 (1 781, 3 033) ng/L], IL-6 [119.08 (23.97, 183.43) ng/L vs 8.39 (2.91, 17.42) ng/L] and IL-8 [13.56 (12.50, 24.52) ng/L vs 2.83 (1.73,6.87) ng/L] were at higher levels ( Z=2.653, P=0.007; Z=2.176, P=0. 030; Z=2.058, P=0.041; Z=3.329, P<0.001; Z=3.162, P=0.001). The KM survival curve showed that the cumulative survival rates of patients with higher serum levels of MIP-1α, sCD25, Elafin, IL-6 and IL-8 were lower than those with low levels at day 14, and the difference was statistically significant (χ 2=12.353, 4.890, 6.551, 10.563, 20.755, P<0.05). Conclusion:The outcomes of patients treated with CAR-T cell therapy bridged to allo-HSCT was correlated with serum MIP-1α, sCD25, Elafin, IL-6 and IL-8 levels after receiving CAR-T therapy. High concentrations of MIP-1α, sCD25, Elafin, IL-6 and IL-8 suggest poor prognosis and can be used as biomarkers to suggest appropriate clinical selection of therapy.

This study evaluated the scientific nature and effectiveness of iterative optimization of prevention and control measures for local outbreaks caused by the BA.2 and BA.5.2 COVID-19 strains in Fujian Province in 2022,to provide a scientif-ic basis for responding to future new or recurrent respiratory infectious diseases.According to the theory of infectious disease dynamics,relevant information regarding the local epidemic situation caused by the BA.2 sub-type Omicron virus strain in March 2022 and BA.5.2 sub-type Omicron virus strain in October 2022 in Fujian Province was collected.The susceptible exposed infectious removed(SEIAR)model of COVID-19 infection with a latent period and asymptomatic infected persons was used to analyze the transmission dynam-ics of two local epidemic situations,and evaluate the preven-tion and control effects.The incubation period of the BA.2 epidemic was 3 days(1～9 days),the intergenerational inter-val was 3 days(1～5 days),and the initial Rt was 3.0(95％CI:2.7～3.3).The incubation period of the BA.5.2 epidemic was 2 days(1～6 days),the intergenerational interval was 1 day(0～2 days),and the initial R,was 1.9(95％CI:1.7～2.1).The fittingresults for the BA.2 and BA.5.2 epidemics were good,and no statistical difference was observed between the predic-ted and actual numbers of cases(x2BA.2=31.53,x2BA.5.2=27.88,P＞0.05).If an emergency response had not been initiated,the BA.2 epidemic would have continued to spread andpeak on April 7th,with an estimated 638 035 cases.The BA.5.2 epidemic would have rapidly spread,reaching a peak on November 14th,with an estimated 685 940 cases.If one incubation period were detected early,the scale of the BA.2 epidemic would have decreased by 25.73％;if two incubation periods were detected early,the scale would have decreased by 79.56％,and if one incubation period had been delayed,the scale would have expanded by 13.72％.If one incubation period had been detected early in the BA.5.2 epidemic,the scale would have decreased by 35.04％;if two incubation periods had been detected early,the scale would have decreased by 92.47％;and if one incubation period had been delayed,the scale would have increased by 19.75％.The guiding ideology,and the prevention and control measures for handling two local epidemics were optimized and iterated.Our study indicated that implementing the"four early"measures ef-fectively decreased the scale of the epidemic,and earlier detection was associated with more significant control effects.This study provides valuable information for the prevention and control of new or recurrent respiratory infectious diseases.

ObjectiveA previous multicenter， single-arm phase Ⅱ clinical study evaluated the efficacy and safety of the PD-1 inhibitor camrelizumab in combination with the antiangiogenic drug apatinib in patients with recurrent/metastatic cervical cancer. In the current study， we aimed to report the patient-reported outcomes （PRO） in patients with advanced cervical cancer. MethodsThe researchers filled out quality of life questionnaire FACT-Cx with the patients face-to-face at the baseline and every two treatment cycles. The patients provided the questionnaire until disease progression. For patients who continued the study， the data cutoff date for the questionnaire was Oct12， 2020. ResultsIn this study， 41 patients who received treatment finished at least one FACT-Cx questionnaire. The scores of FACT-Cx questionnaire at baseline， the first 6 cycles， and after 6 cycles of treatment （range， 7-15cycle） were 114.53±18.23， 124.08±15.23 and 132.82±21.97， respectively. The scores of questionnaire at the first 6 cycle and after 6 cycles of treatment were significantly increased when compared with those at baseline （P＜0.05）. With respect to each dimension of the FACT-Cx questionnaire， physical status （such as mental state， limb pain）， emotional status （such as sadness， tension）， functional status （such as daily activities） and additional concerns （such as sexual function）， the average scores of these dimensions was significantly higher after 6 treatment cycles than those at baseline （P<0.05）. Social/family status dimensions （such as family relationships） did not change significantly. In the first 6 cycles， the incidence of grade 3 to 4 adverse events （AEs） was 71.11%. However， the incidence of grade 3 to 4 AEs decreased significantly to 25.0% after 6 treatment cycles， with the frequencies of hypertension and fatigue decreasing significantly. ConclusionsCamrelizumab combined with apatinib significantly improves the overall quality of life of patients with recurrent/metastatic cervical cancer. The scores of FACT-Cx questionnaire in multiple dimensions， such as physiological status， emotional status， functional status， and the additional status were significantly increased. Moreover， the questionnaire scores still increase after 6 treatment cycles compared with those of the first 6 cycles， indicating that the improvement of quality of life is durable.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.
