ObjectiveTo investigate the potential mechanism of action of the Qufeng Tongqiao Cough-relieving Decoction （祛风通窍止咳方， QTCD） in the treatment of upper airway cough syndrome （UACS）. MethodsTwenty-four guinea pigs were randomly divided into blank group， model group， traditional Chinese medicine （TCM） group， and inhibitor group， with six guinea pigs in each group. Except for the blank group， guinea pigs were sensitized with ovalbumin and aluminum hydroxide via intraperitoneal injection， followed by ovalbumin nasal drops combined with smoke exposure to establish the UACS model. After modeling， the TCM group was administered QTCD 0.9 g/（100 g·d） by gavage， the inhibitor group received the transient receptor potential vanilloid receptor 4 （TRPV4） inhibitor GSK2193874 1 mmol/L， 5 min by nebulisation， and the blank group and model group were given 2 ml/（100 g·d） normal saline by gavage once daily. After 7 days of treatment， a cough provocation test was performed using 0.4 mol/L citric acid. The levels of IgE in serum and inflammatory cytokines， including interleukin-6 （IL-6）， interleukin-8 （IL-8） in serum， bronchoalveolar lavage fluid （BALF）， and nasal lavage fluid （NLF） were detected by enzyme-linked immunosorbent assay （ELISA）. Histopathological changes in lung and nasal mucosal tissues were observed by hematoxylin-eosin （HE） staining. Immunohistochemistry was used to detect the protein levels of TRPV4， substance P （SP）， and calcitonin gene-related peptide （CGRP） in lung and nasal mucosal tissues. Real-time polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of TRPV4， SP， and CGRP in lung tissues. ResultsHE staining showed significant structural damage and infiltration of inflammatory cells in the lung and nasal mucosal tissues in the model group， while the TCM group and inhibitor group showed improved pathological changes. Compared with the blank group， the model group showed increased cough frequency， serum IgE level， and IL-6 and IL-8 levels in serum， BALF， and NLF. The protein levels of TRPV4， SP， and CGRP in lung and nasal mucosal tissues and their mRNA expression were elevated （P＜0.05 or P＜0.01）. Compared with the model group， the TCM group and inhibitor group showed reduced cough frequency， serum IgE level， and TRPV4 and SP mRNA expression in lung tissues. The TCM group showed reduced IL-6 and IL-8 levels in serum， BALF， and NLF， and reduced TRPV4 and CGRP protein levels in lung and nasal mucosal tissues. The inhibitor group showed reduced IL-6 and IL-8 levels in serum， BALF， and NLF， reduced IL-6 in BALF， reduced IL-8 in NLF， and decreased TRPV4， SP， and CGRP protein levels in lung tissues and SP and CGRP protein levels in nasal mucosal tissues （P＜0.05 or P＜0.01）. Compared with the TCM group， the inhibitor group had increased serum IgE， IL-6， and IL-8 levels， increased IL-6 level in BALF， and increased IL-8 levle in NLF， but decreased SP protein level in lung tissues and increased TRPV4 and SP mRNA expression in lung tissues （P＜0.01）. ConclusionQTCD effectively reduces cough frequency in the UACS guinea pig model. Its mechanism may involve inhibiting the activation of the TRPV4 pathway， improving airway neurogenic inflammation， alleviating inflammatory responses， and reducing cough hypersensitivity.

Objective:To establish the objective of zero inventory management of in vitro diagnostic reagents,to evaluate the quality of supply chain,and to improve the existing problems in the supply of reagents.Methods:The problems existing in the management of in vitro diagnostic reagents were analyzed from the aspects of inventory,supply efficiency and product quality,and the management system of hospital operation,management quality and patient benefit optimization was established,and the zero-inventory management path and quality evaluation model were constructed.85 models of 21 types of in vitro diagnostic reagents purchased by Jiangsu Subei People's Hospital from January 2020 to March 2023 were selected.According to different supply chain quality management methods,on-demand inventory management mode(referred to as mode 1)and zero inventory management mode(referred to as mode 2)were adopted respectively.The demand procurement,inventory management and clinical use effects of the two management modes were compared.Results:The reagent procurement demand compliance rate,supply capacity high-quality quality rate and clinical use matching rate of mode 2 were(93.35±3.62)%,(94.87±2.63)% and(96.08±2.31)%,respectively,which were higher than those of mode 1,the difference was statistically significant(Z=2.489,2.836,2.838,P<0.05).The number of cases of long-term overstocking of products,substandard environment and untimely information in mode 2 were(2.92±2.54)cases,(2.83±1.59)cases and(5.58±3.12)cases,respectively,which were lower than those in mode 1,the difference was statistically significant(Z=2.959,3.037,3.703,P<0.05).The satisfaction of clinical departments,medical technology departments and procurement center with the supply,distribution and information communication of in vitro diagnostic reagents in mode 2 were 97.8% and 93.3%,97.0% and 87.9%,100% and 84.6%,respectively,which were higher than those in mode 1,the difference was statistically significant(x2clinical departments=5.428,6.133,x2medical technology departments=3.958,3.937,x2procurement center=5.159,4.996,P<0.05).Conclusion:The zero inventory management model can improve the standardization of in vitro diagnostic reagent demand procurement,reduce the incidence of backlog failure in inventory management,and improve the quality of clinical supply services.

ObjectiveTo understand the utilization of preconception healthcare services and the influencing factors among the women expecting additional childbirth in Jiading District， Shanghai， and to provide references for promoting the utilization of preconception healthcare services under the new population policy. MethodsA questionnaire survey on the utilization of preconception healthcare services and related influencing factors was carried out among 682 women expecting additional childbirth across six subdistricts in Jiading District， Shanghai. The results were statistically analyzed. ResultsThe average age of the women was （31.7±4.5） years， 30.2% of whom were ≥35 years old. The proportion of women having their third or subsequent children was low， at 16.4%. A significant majority， 92.4%， were found to have various risk factors during initial pregnancy screening. The utilization rate of preconception healthcare services among women seeking additional childbirth was relatively low at 26.7%. Awareness of the free preconception check-up program in Jiading District was also low at 28.6%， and the utilization rate for these services was even lower at 7.69%. Unplanned pregnancies were the primary reason for not utilizing preconception healthcare services， accounting for 63.6%. The results of multifactorial binary logistic regression analysis showed that the utilization rate of preconception healthcare services before the current pregnancy was higher for women aged between 35 and 39 compared to women aged ≤29 years old （OR=1.789， 95%CI： 1.033‒3.099）. Women with planned pregnancies had a higher utilization of preconception healthcare services prior to this pregnancy （OR=4.164， 95%CI： 2.627‒6.602）. Women who had received preconception care prior to their first birth had a higher utilization rate of preconception care prior to the current pregnancy （OR=7.534， 95%CI： 4.954‒11.456）. Women without a family history of chronic diseases had a higher utilization rate of preconception healthcare services （OR=1.903， 95%CI： 1.083‒3.345）. ConclusionUnder the context of three-child policy， the proportion of women seeking three or more children in Jiading District is low. Most of these women have risk factors identified during initial pregnancy screenings. The utilization rate of preconception healthcare services and the awareness of the free preconception screening program in Jiading District are both low. Unplanned pregnancies remain the primary reason for failing to receive timely preconception healthcare services. Age， whether the pregnancy was planned， whether the women had received preconception healthcare services before their first baby and family history of chronic diseases are the main factors affecting the utilization of preconception healthcare services. Relevant departments should enhance the promotion of preconception healthcare service programs， especially for women of childbearing age who have not yet given birth， so as to improve the utilization rate of preconception health care services.

Objective:To explore the application effect of checklist teaching in clinical nursing internship teaching in nephrology.Methods:A total of 49 full-time undergraduate nursing students who interned between July and December 2023 were selected as the observation group, while 49 full-time undergraduate nursing students who interned between July and December 2022 were selected as the control group. During the internship teaching process, the observation group received a checklist teaching, while the control group received traditional teaching. The effectiveness of the checklist teaching method was evaluated by comparing the internship performance, sense of belonging, and satisfaction of both students and teachers between two groups of nursing students. SPSS 26.0 was used for chi-square test and t test. Results:After teaching, the theoretical scores [(97.45±1.63) vs. (93.26±2.38)] and operational skills scores [(96.15±1.90) vs. (93.25±2.46)] were significantly higher in the observation group than in the control group ( P<0.05). After teaching, the observation group had significantly higher scores for the sense of belonging and satisfaction scores in all dimensions during the internship compared to the control group ( P<0.05). After teaching, the teaching staff showed significantly higher satisfaction scores in all dimensions in the observation group than in the control group ( P<0.05). Conclusions:Applying checklist teaching to clinical teaching of nephrology nursing can significantly improve the internship assessment scores of students, promote the teaching performance of teaching staff, and enhance the satisfaction of both teachers and students.

Purpose To explore the value of predicting risk classification of gastrointestinal stromal tumors(GIST)based on the model established by dural-phase enhanced CT based radiomics.Materials and Methods Totally 200 patients with pathologically confirmed GIST from October 2017 to July 2023 in the Affiliated Hospital of Zunyi Medical University were enrolled,including 69 cases with low-risk group(very low-risk,low-risk)and 131 with high-risk group(medium-risk,high-risk).All patients were randomly divided into training set(n=139)and validation set(n=61)at the ratio of 7∶3.Univariate and multivariate Logistic regression analysis were used on clinical data and CT sings in the training set to obtain clinical-CT features for predicting the risk grade of GIST,and clinical-CT models were constructed.The radiomics features were extracted and screened from the three data sets of enhanced CT arterial phase,venous phase and arterial+venous phase,and the radiomics model was constructed to obtain the optimal radiomics features,respectively.The optimal radiomics features were obtained and combined with the clinical-CT features,a combination model was constructed and the normogram was drawn.The predictive efficiency of these models was evaluated by area under the curve(AUC).Results Tumor diameter was an independent predictor of GIST risk classification(OR=1.070,P＜0.001).The AUC of the combination model,model arterial+venous phase radiomics and model clinical-CT in the training set were 0.948,0.896 and 0.873,respectively;those in the validation set were 0.886,0.825 and 0.870,respectively.The AUC of the above three models showed statistical difference(Z=-3.167,-2.316,P＜0.05).Conclusion The radiomics features based on enhanced CT have good value in predicting risk classification of GIST.Compared with model clinical-CT and model radiomics,the combination model is the most effective in predicting the risk classification of GIST.

Objective:To analyze the changing trend of intracerebral hemorrhage (ICH) incidence among residents with different characteristics during 9 years of comprehensive hypertension prevention and control (hypertension prevention and control) in Tengzhou from 2013 to 2021.Methods:From January 1, 2013 to December 31, 2021, the new ICH cases collected by the Center for Disease Control and Prevention in Tengzhou City were analyzed to calculate the incidence of ICH, and the trend of its distribution was analyzed among residents with different ages, sexes, and between urban and rural areas. The registered population information came from Tengzhou Public Security Bureau. Age and sex standardized incidence was calculated based on the 7th National Population Census in 2020. The Cochran-Armitage test was used to analyze the time and age trends of the incidence.Results:The overall ICH crude and standardized incidence in Tengzhou City decreased from 97.30/100 000 to 52.13/100 000 ( Z=-9.93, P<0.001) and 119.30/100 000 to 50.69/100 000 ( Z=-15.40, P<0.001) from 2013 to 2021, and both elevated to form a single peak in 2020, with 22.58% ( χ 2=24.02, P<0.001) and 18.09% ( χ 2=17.08, P<0.001) higher than in 2019, respectively. The trends in male and female incidence over the same period were similar to the overall trends, and the incidence was higher in males than in females in all years. The incidence of ICH increased with age in all years. The difference of increase in male incidence rate in 2020 was statistically significant in three age groups ≥45 years compared with 2019 (36.29%, 23.57% and 16.18%, respectively, χ 2=6.73, 4.65, 4.00, P<0.001). The incidence of ICH decreased by 70.07% and 36.23% ( Z=18.44, 5.22, P<0.001) in urban and rural areas respectively from 2013 to 2021, whereas increased by 34.15% ( χ 2=10.88, P<0.01) and 22.08% ( χ 2=18.63, P<0.001) in 2020 compared with 2019 separately. Conclusions:The incidence of ICH in Tengzhou from 2013 to 2021 showed a significant downward trend, with the decrease in the incidence of ICH in women exceeding that in men. The decrease in the incidence of ICH in urban areas exceeded that in rural areas, and male morbidity seemingly had a younger trend.

Objective To explore the characteristics of opportunistic infections(OIs)in HIV-infected indi-viduals with suboptimal immune reconstitution after ART treatment so as to provide a reference for preventing and managing HIV infections.Methods The clinical data including opportunistic infections specifically were acquired from 112 HIV-infected individuals with suboptimal immune reconstitution from the outpatient department of Wuming Hospital,Guangxi Medical University.The impact of baseline CD4+T lymphocyte counts on the incidence,type,and mixed infection rates of the opportunistic infections were analyzed.Results The opportunistic infection rate among the 112 HIV-infected individuals with suboptimal immune reconstitution was 42.86%,among which fungal infections were the most commonly seen.The opportunistic infection rate of the patients with a baseline of CD4+T lymphocyte counts≤50/μL was significantly higher than that of the patients with a baseline of CD4+T lymphocyte counts>50/μL,and there was no significant difference in the type of opportunistic infections as well as the rate of mixed infections.Conclusion HIV-infected people with suboptimal immune reconstitution in Guangxi are susceptible to HIV OIs.Among them,the group with a baseline CD4+ T lymphocyte counts≤50/μL has a higher rate of OIs,mainly fungal infections.

Objective:To study the effect of ranibizumab on retinal oxidative stress in a rat model of choroidal neovascularization (CNV) and its mechanism.Methods:Sixty SPF male SD rats aged 10 weeks were randomly divided into normal control group, model control group, ranibizumab group, nuclear factor erythroid 2-related factor 2 (Nrf2) inhibitor (ML385) group, ranibizumab+ ML385 group, with 12 rats in each group according to a random number table.Except for the normal control group, the CNV model was established in the other four groups via krypton laser induction.According to grouping, the ranibizumab group, ML385 group and ranibizumab+ ML385 group were intravitreally injected with 1 μl of ranibizumab, ML385 and ranibizumab+ ML385, respectively.Model control group and normal control group received an intravitreal injection of normal saline of equal volume.The CNV area was measured through choroidal wholemounts.Pathological change of the retina was observed by hematoxylin and eosin staining.Expressions of Nrf2, superoxide dismutase (SOD) and quinone oxidoreductase 1 (NQO1) were detected using Western blot and real-time PCR.The use and care of animals complied with laboratory animal welfare guidelines.The study protocol was approved by the Laboratory Animal Welfare and Ethics Committee of Tengzhou Central People's Hospital (No.JN.No20210214S1200430[121]).Results:CNV areas of the model control group, ML385 group and ranibizumab+ ML385 group were (23.01±1.52)×10 3, (30.23±2.01)×10 3 and (18.56±1.85)×10 3 μm 2, respectively, which were significantly higher than (12.35±1.22)×10 3 μm 2 of ranibizumab group (all at P<0.001). The CNV area of ranibizumab+ ML385 group was smaller than that of model control group and ML385 group, and the CNV area of ML385 group was larger than that of model control group, showing statistically significant differences (all at P<0.001). Hematoxylin and eosin staining showed that the structural damage of the retinal pigment epithelium-choroid-sclera complex was slighter in ranibizumab group than model control group, severer in ranibizumab+ ML385 group than ranibizumab group but slighter than model control group, severer in ML385 group than model control group.The mRNA and protein expressions of Nrf2, SOD and NQO1 of ranibizumab group were lower than those of normal control group but higher than those of model control group, ML385 group and ranibizumab+ ML385 group, and the differences were statistically significant (all at P<0.05). The mRNA and protein expressions of Nrf2, SOD and NQO1 were higher in ranibizumab+ ML385 group than model control group and ML385 group, showing statistically significant differences (all at P<0.05). Conclusions:Ranibizumab can inhibit the growth of CNV induced by krypton laser and reduce RPE damage caused by retinal oxidative stress.The mechanism is related to the activation of Nrf2/ARE pathway.

Objective:To investigate the effects of computerized cognitive remediation therapy (CCRT) combined with social skill training on the improvement of negative symptoms of schizophrenia.Methods:A total of 102 schizophrenic patients who received treatment in Shanxi Province Social Welfare Kangning Psychiatry Hospital from March 2019 to June 2021 were included in this study. They were randomly divided into an intervention group and a control group ( n = 51/group). During the intervention process, because of the reasons such as midway discharge, only 93 patients were included in the final analysis, consisting of 47 patients in the intervention group and 46 patients in the control group. All patients received social skills training. Patients in the intervention group received 8-week CCRT. The Positive and Negative Syndrome Scale and Social Skills Checklist were used to evaluate curative effect in the two groups. Results:After treatment, total score of the Positive and Negative Syndrome Scale and the score of negative symptoms in the intervention group were (46.36 ± 9.33) points and (11.15 ± 3.53) points, respectively, which were significantly lower than (51.06 ± 10.26) points and (16.42 ± 4.75) points in the control group ( t = 2.07, 5.41, both P < 0.05). The total score of Social Skills Checklist, conflict resolution ability score and relationship building ability score in the intervention group were (16.05 ± 6.85) points, (3.36 ± 1.65) points and (3.14 ± 1.83) points, respectively, which were significantly lower than (21.08 ± 8.24) points, (5.92 ± 2.35) points and (6.75 ± 2.51) points, respectively ( t = 2.87, 5.34, 7.00, all P < 0.01). Conclusion:CCRT combined with social skill training can effectively improve the negative symptoms of patients with schizophrenia.

Organoid is a newly developed cellular there-dimensional culture system in recent years. Organoids have a three-dimensional structure, which is similar to that of the real organs. Together with the characteristics of self-renewal and reproduction of tissue origin, organoids can better simulate the function of real organs. Organoids provide a new platform for the study of organogenesis, regeneration, disease pathogenesis, and drug screening. The digestive system is an essential part of the human body and performs important functions. To date, organoid models of various digestive organs have been successfully established.
