OBJECTIVE To investigate the use of drugs and the development of pharmaceutical care in the tight medical alliance （shorted for “medical alliance”） of Wanzhou District of Chongqing， and provide reference for the further construction of the medical alliance. METHODS A survey form was designed and distributed to 21 constituent units （5 leading units and 16 member units） of 5 medical alliances in Wanzhou District of Chongqing. The statistical analysis was conducted in aspects of basic drug allocation and use， pharmaceutical personnel team construction， the development of pharmaceutical care， and rational use of antibiotics. RESULTS Among the 21 constituent units， 4 leading units and 14 member units achieved the target for the proportion of essential drug procurement varieties， with a total compliance rate of 85.71%； 4 leading units and 13 member units achieved the target for the proportion of national essential drug allocation and usage amount， with a total compliance rate of 80.95%. The proportions of personnel with doctoral degrees in the 5 leading units and 16 member units were 1.71% and 0 respectively， and the proportions of personnel with senior professional titles were 8.56% and 1.63%， respectively. A total of 5 pharmacy or pharmaceutical combined outpatient clinics were set up in the 21 medical alliance units， and 5 clinical pharmacy information service platforms were established； all 5 leading units were able to regularly carry out clinical pharmacy projects， while only 4 out of 16 member units had conducted medical order review and evaluation. The proportions of irrational use of antibiotics in outpatient prescriptions and inpatient medical records of the 16 member units （4.81%， 5.21%） were significantly higher than those of the 5 leading units （2.80%， 4.00%）. CONCLUSIONS The allocation and usage of national essential drugs in 21 constituent units from Wanzhou District of Chongqing are both in good standing. However， the data on the allocation of pharmaceutical professionals and the number， qualifications， and job titles of clinical pharmacists in member units are generally low. Moreover， the pharmaceutical service projects and service quality in member units need to be further improved.

Psychological factors have become significant contributors to the onset and progression of insomnia. This article explored the treatment of insomnia from the perspective of “liver governs wei qi （defensive qi）”. The concept of “liver governs wei qi （defensive qi）” is summarized in three aspects， firstly， the liver assists the spleen and stomach in transformation and transportation， governing the generation of wei qi； secondly， the liver aids lung qi diffusion and dispersion， governing the distribution of wei qi； thirdly， the liver regulates circadian rhythms， governing the circulation of wei qi. It is proposed that the clinical treatment of insomnia should focus on the following methods： for regulating the liver to harmonize the five viscera， and facilitate the circulation of wei qi， medicinals entering the liver channel include Chaihu （Bupleuri radix）， Baishao （Paeoniae Radix Alba）， Zhizi （Gardeniae Fructus）， and Suanzaoren （Ziziphi Spinosae Semen） could be commonly used； for nourishing the liver， the treatment should align with the day-night rhythm， and herbs such as Baihe （Lilium）， Hehuan （Albizia julibrissin）， and Yejiaoteng （Polygoni multiflori caulis） are commonly used； for soothing the liver and address both mental and physical health to calm wei qi， treatment should advocate verbal counseling， psychological regulation， and health education. Ultimately， this treatment approach can free liver qi to flow， soothe qi movement， restore the motion of wei qi， regulate during day and night， balance yin and yang， and resolve insomnia effectively.

ObjectiveTo explore the optimal construction method and the biological basis for establishing a mouse model of ischemic heart disease（IHD） with Qi and Yin deficiency syndrome by intraperitoneal injection of isoproterenol（ISO）. MethodsA total of 144 male C57BL/6J mice were randomly assigned into three normal groups and nine model groups according to body mass， with 12 mice in each group. The model groups 1， 4， and 7 were administered ISO via intraperitoneal injection at a dose of 5 mg·kg^-1·d^-1 for four consecutive days， the model groups 2， 5， and 8 received ISO at a dose of 10 mg·kg^-1·d^-1 for seven consecutive days， while the model groups 3， 6， and 9 were given ISO at a dose of 15 mg·kg^-1·d^-1 for 14 consecutive days. The normal groups were administered an equivalent volume of normal saline via intraperitoneal injection. After the modeling process， body mass， 24-hour food and water intake， grip strength， and spontaneous activity of the mice were measured. Cardiac function was assessed using echocardiography， the serum levels of norepinephrine（NE）， cyclic adenosine monophosphate（cAMP）， and cyclic guanosine monophosphate（cGMP） were determined via enzyme-linked immunosorbent assay（ELISA）. The content of adenosine triphosphate（ATP） in myocardial tissue was measured by biochemical analysis， while histopathological changes in myocardial tissue were observed via hematoxylin-eosin（HE） staining. An orthogonal experimental design was applied for intuitive analysis and variance analysis to screen the optimal modeling conditions of the mouse model of IHD with Qi and Yin deficiency syndrome. A data-dependent acquisition（DDA） proteomic technique was employed to quantitatively detect differentially expressed proteins in myocardial tissue between the optimal model group and the normal group. And bioinformatics analysis was conducted to explore the potential biological mechanisms underlying the Qi and Yin deficiency model of IHD. ResultsOrthogonal results showed that the injection cycle had a great influence on model establishment， and the optimal modeling condition was identified as intraperitoneal injection of ISO at 15 mg·kg^-1·d^-1 for 14 consecutive days. Under this condition， compared with the normal group， the model group demonstrated significant reductions in body mass， food intake， water intake， grip strength， total distance and average speed of exercise， ejection fraction（EF）， fractional shortening（FS）， serum levels of NE and cGMP， and myocardial ATP content（P<0.01）， while immobility time， cAMP level， and the cAMP/cGMP value were significantly increased（P<0.05， P<0.01）. HE staining results revealed that myocardial tissue in the model group had disordered cell arrangement， inflammatory cell infiltration， myocardial fiber rupture， and fibrous tissue proliferation. Proteomic analysis identified 141 differentially expressed proteins in the model group compared with the normal group， with 52 up-regulated and 89 down-regulated. Gene Ontology（GO） functional annotation and Kyoto Encyclopedia of Genes and Genomes（KEGG） pathway enrichment analysis indicated that the cellular components（CC） were mainly related to mitochondria and the inner mitochondrial membrane， the biological processes（BP） were associated with complement activation， platelet activation， and responses to metal ions， suggesting that the potential functional pathways involved the complement and coagulation cascade， as well as porphyrin metabolism. ConclusionContinuous intraperitoneal injection of ISO at a dose of 15 mg·kg^-1 for 14 days successfully establishes a mouse model of IHD with Qi and Yin deficiency syndrome， and the underlying mechanisms may be related to the regulation of iron ions by complement C3， C5 and Cp， and plays a role in the regulation through the BP of complement activation， platelet activation， and responses to metal ions， and the signaling pathways of the complement and coagulation cascade and porphyrin metabolism.

Objective:To observe the clinical efficacy of Xinyue Decoction combined with fluoxetine hydrochloride in the treatment of cognitive impairment of senile depression.Methods:A randomized controlled trial study was conducted. Totally 116 elderly patients with depression accompanied by cognitive impairment were set as observation subjects, and were divided into a control group and an experimental group using random number table method, with 58 patients in each. The control group received treatment with fluoxetine hydrochloride capsules, while the experimental group was administered Xinyue Decoction Granules in addition to the treatment regimen of the control group. The treatment lasted for 8 weeks for both groups. Comparison was made between the two groups regarding the changes in TCM syndrome scores. Hamilton Depression Scale (HAMD-24) was used to assess the degree of depression, and Montreal Cognitive Assessment (MoCA BJ) was used to assess cognitive ability; the serum levels of brain-derived neurotrophic factor (BDNF), IL-1β, IL-6 and TNF-α were detected by ELISA; the adverse reactions during treatment were observed and recorded, and the clinical efficacy was evaluated.Results:The total effective rate of TCM syndromes was 90.4% (47/52) in the experimental group and 75.5% (40/53) in the control group, with statistical significance ( χ2=4.11, P<0.05); the total effective rate of MoCA-BJ was 76.9% (40/52) in the experimental group and 58.5% (31/53) in the control group, with statistical significance ( χ2=4.61, P<0.05); the total effective rate of HAMD-24 was 88.5% (46/52) in the experimental group and 71.7% (38/53) in the control group, with statistical significance ( χ2=4.07, P<0.05). After treatment, the TCM syndrome score, HAMD-24 and MoCA-BJ scores of the experimental group were lower than those in the control group ( t=-3.51, -5.11, 2.39, P<0.01 or P<0.05); the level of serum BDNF [(10.49±1.76) ng/L vs. (9.61±1.85) ng/L, t=2.28] in the observation group was higher than that of the control group ( P<0.05), and the levels of IL-1β, IL-6 and TNF-α were lower than those in the control group ( t=-2.50, -2.46, -2.18, P<0.05). During the treatment, the incidence of adverse reactions was 5.77% (3/52) in the experimental group and 7.55% (4/53) in the control group, without statistical significance ( χ2=0.13, P>0.05). Conclusion:Xinyue Decoction combined with fluoxetine hydrochloride can reduce the degree of depression in elderly patients with cognitive impairment of depression, improve the cognitive ability of patients and clinical efficacy.

Objective:To develop a nomogram model for predicting the risk of ventilator-associated pneumonia (VAP) in patients with mechanical ventilation (MV) and to validate the stability of the prediction performance of the model.Methods:The patients with MV admitted to the Department of Critical Care Medicine of General Hospital of Ningxia Medical University from January 2019 to December 2022 were retrospectively selected according to the order of admission. The patients with MV were divided into the non-VAP group and the VAP group according to whether VAP occurred. The clinical data of the two groups, including general information, disease, medication, condition, and operation-related indicators were collected as candidate predictors of the model for comparison. Multivariate logistic stepwise forward regression analysis was used to screen the predictors that finally entered the model, and a nomogram model was constructed. The model discrimination was evaluated by the area under the receiver operating characteristic curve (AUC), the diagnostic test results of the model at the predicted threshold were calculated, the Hosmer-Lemeshow test was used to evaluate the model fit, and the Bootstrap resampling was used 1 000 times for internal validation, and model calibration and clinical applicability were evaluated by calibration curve and decision analysis curve, respectively.Results:A total of 1 250 patients with MV were included, including 1 102 patients in the non-VAP group and 148 patients in the VAP group, and the prevalence of VAP was 11.8%. The detection of multidrug-resistant organisms, chronic kidney disease, brain injury, oxygenation index, the place of tracheal intubation, reintubation, use of bronchoscopy, use of antibiotics, and MV duration were model predictors of VAP. The AUC of the nomogram model was 0.917 (95% CI: 0.895-0.939), the maximum Youden index of 0.697 corresponded to a prediction threshold of 0.096. The model accuracy, sensitivity and specificity were 0.836, 0.865, and 0.832, respectively. The positive predictive value and the negative predictive value were 0.409 and 0.979, respectively. The Hosmer- Lemeshow test indicated that the model fit well ( P=0.938). The results of the internal validation of the model showed that the predicted risk of the calibration curve was generally consistent with the actual risk, and the decision threshold probability of the decision analysis curve ranged from 2% to 90%. Conclusions:The nomogram model developed in this study is simple, convenient and has relatively stable prediction performance, which can be externally validated to evaluate the extrapolation of the model, and provide a basis for individualized clinical prediction of the risk of VAP in patients with MV.

ObjectiveTo systematically review the intervention effect of cognitively engaging physical activity (CEPA) on executive function of children and adolescents. MethodsLiteratures in Chinese and English were retrieved from databases of Web of Science, PubMed, Medline, EBSCO and CNKI, from the establishment to November 30th, 2023. According to the inclusion and exclusion criteria, the literatures that met the requirements were screened, and their quality was evaluated and systematically reviewed. ResultsA total of 15 literatures were included, published between 2014 and 2023, from eight countries, involving 1 806 subjects aged four to 16 years. The average score of PEDro scale was 6.6. The intensity of the CEPA intervention ranged from 64% to 93% HR_max, the duration of a single session ranged from ten to 60 minutes, and the frequency of the intervention was two to five sessions a week, for four to 24 weeks. Specific forms of CEPA included football, basketball and floorball combined with cognitive tasks; running, jumping, squatting, sitting, spinning and balancing combined with cognitive tasks; and exergaming combined with cognitive tasks. Eleven researches showed positive effects of CEPA intervention on at least one component of executive function. However, six of the seven researches involving working memory failed to verify the positive effects. Twelve researches compared the intervention effects of CEPA and rutine exercise or regular physical education classes, and nine researches found that CEPA was more effective on executive function. ConclusionThe CEPA is effective on the executive function of children and adolescents, specifically on cognitive flexibility; it shows inconsistent effects on inhibitory control, and its effect on working memory has not been verified. The intervention types of CEPA are divided into ball games combined with cognitive tasks, basic motor skills training combined with cognitive tasks, and exergaming combined with cognitive tasks.

Objective:To analyze the current situation of myopia and its related factors among primary school students in a certain district of Beijing City in 2022, and provide a basis for the risk assessment of myopia among primary school students.Method:In June 2022, a cluster sampling method was used to include 376 third-grade students from a primary school in a certain district of Beijing. A questionnaire survey was conducted to collect basic information about students, including eye usage habits, reading and writing postures, and parents′ myopia conditions. The examination of students′ distant visual acuity and refractive status was performed. A multivariate logistic regression model was used to analyze the related factors of myopia occurrence.Results:The age of 376 primary school students was (8.87±0.417) years old, with 48.40% (182) being male. A total of 196 myopia cases were identified, with a myopia rate of 52.13%. The results of the multivariate logistic regression model analysis showed that students who sometimes read while lying down ( OR=2.003, 95% CI: 1.128-3.555), often read while lying down ( OR=18.853, 95% CI: 4.512-78.778), had outdoor activity time less than 120 minutes per day ( OR=4.937, 95% CI: 2.4464-9.892), were engaged in indoor break activities ( OR=4.995, 95% CI: 2.773-8.996), performed eye exercises less than once per day ( OR=8.710, 95% CI: 4.464-16.995), had a reading distance from the book less than 30 cm ( OR=5.098, 95% CI: 2.410-10.787), occasionally maintained a fist distance from the edge of the desk ( OR=1.918, 95% CI: 1.086-3.385), and had high school desks and tables ( OR=5.325, 95% CI: 1.465-19.359) could have a higher risk of myopia occurrence, compared with those who never read while lying down, had outdoor activity time more than 120 minutes per day, maintained outdoor break activities, performed eye exercises more than once per day, had a reading distance from the book more than 30 cm, always maintained a fist distance from the edge of the desk, and had short school desks and tables. Conclusion:The incidence rate of myopia among primary school students in a certain district of Beijing City. in 2022 is relatively high. The occurrence of myopia is related to insufficient outdoor activity time and poor eye usage habits.
