Objective: To investigate the epidemiological and spatio-temporal characteristics of influenza in Jiaxing City, Zhejiang Province, so as to provide insights into perfecting the prevention and control strategies of influenza. Methods: Data of influenza in Jiaxing City from 2019 to 2023 were collected from the Chinese Disease Prevention and Control Information System. Population data of the same period were collected from the Zhejiang Health Information Network Reporting System. The epidemiological characteristics of influenza were analyzed using descriptive analysis. Vector map information was collected from the Open Street Map, and the spatio-temporal clustering characteristics of influenza were analyzed using spatial autocorrelation and spatio-temporal scanning. Results: A total of 181 501 cases of influenza were reported in Jiaxing City from 2019 to 2023, with an average annual reported incidence of 653.93/105. The majority of cases were aged 5 to <15 years (59 785 cases, 32.94%). The majority of the occupations were students (78 239 cases, 43.11%) and pre-school children (33 715 cases, 18.58%). The county (city, district) with the highest reported incidence was Haining City (1 451.70/105), and the town (street) with the highest reported incidence was Chang'an Town (1 932.78/105). Spatial autocorrelation analysis showed that the incidence of influenza in Jiaxing City from 2019 to 2023 had positive spatial correlations (all Moran's I>0, all P<0.05), with a high-high clustering in the southern region. Spatio-temporal scanning analysis showed that there was a spatio-temporal clustering of influenza in Jiaxing City from 2019 to 2023, with the southern region being the primary-type clustering area and the period between November and January of the following year being the clustering time. Conclusion There was a significant spatio-temporal clustering of influenza in Jiaxing City from 2019 to 2023, with winter being the peak season and the southern region being the primary area.

It is believed that diabetes complicated with coronary heart disease is closely related to the functional interplay of the heart， spleen， and kidneys. This paper proposed the concept of the heart-spleen-kidney as a unified system for understanding and treating the disease. At the early stage， spleen and kidney deficiency leads to the internal accumulation of phlegm， dampness， and turbid lipids， causing impaired blood circulation and vascular obstruction， so treatment should focus on tonify the kidneys and strengthening the spleen， activating blood circulation and resolving stasis， using the self-prescribed Tangxin Maiwen Formula （糖心脉温方）. As the disease progresses， further decline of spleen and kidney function results in inadequate nourishment of the heart， leading to blood stasis and the accumulation of phlegm， dampness， and turbid lipids， which may transform into pathogenic heat and toxins， causing heart damage， then treatment should emphasize on boosting qi and nourishing yin， clearing heat， activating blood and resolving toxins， using the self-prescribed Tangxin Maiqing Formula （糖心脉清方）. In advanced stages， three zang organs， the heart， spleen， and kidneys， become severely impaired， leading to mental activity fail to be nourished and abnormal cognitive functions， so treatment should focus on harmonizing the three zang organs simultaneously， using the self-prescribed Yunpi Tiaoxin Decoction （运脾调心汤）. This approach aims to provide a clinical framework for the diagnosis and treatment of diabetes with coronary heart disease.

OBJECTIVE To systematically summarize the working model of pharmacy consultation in medical institutions in China， and to provide reference for the normalization of process， standardization of content and homogenization of services of pharmacy consultation. METHODS A systematic search of Chinese and English literature databases was conducted to incorporate the literature on the working model of pharmacy consultation published by medical institutions in China. Two researchers screened and extracted the key information， and ultimately conducted qualitative summary and descriptive analysis. RESULTS Based on the included 11 articles， the pharmacy consultation working models were explored by clinical pharmacists in China. The contents of consultation mainly involved anti-infection， parenteral nutrition， cancer pain， etc. The general concept of pharmacy consultation should refer to the constructed flowchart， specific consultation problems could refer to the pathway， mind map， or decision tree and other framework guidance to carry out the work. Finally， consultation opinions could be written according to the consultation system or specialty consultation templates， and the adoption of a new working model （such as pharmacist active consultation） could also promote the number and acceptance rate of pharmacy consultation. CONCLUSIONS A series of working models of pharmacy consultation have been initially explored in medical institutions in China. However， it is not yet perfect and lacks a unified quality control and evaluation system for pharmacy consultation， which should be the focus of future research and practice.

Objective To investigate the clinical efficacy of tiotropium bromide in the treatment of patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)complicated with acute respiratory failure.Methods A total of 106 patients with AECOPD complicated with acute respiratory failure admitted to the First People's Hospital of Huzhou from March 2019 to March 2022 were selected and divided into observation group and control group according to random number table method,with 53 cases in each group.Both groups were given routine treatment.The control group was treated with noninvasive biphasic positive airway pressure ventilation.The observation group was treated with tiotropium bromide on the basis of control group.Both groups were treated for 14 days.The clinical efficacy,lung function,blood gas index,inflammatory factors and adverse reactions were compared between two groups.Results The total effective rate of observation group was significantly higher than that of control group(94.34%vs.79.25%,χ2=5.267,P=0.023).After treatment,forced expiratory volume in one second(FEV1),FEV1/forced vital capacity,peak expiratory flow,pH,percutaneous arterial oxygen saturation and arterial partial pressure of oxygen in observation group were significantly higher than those in control group(P<0.05),while arterial partial pressure of carbon dioxide,interleukin-6,interleukin-8,tumor necrosis factor-α and hypersensitive C-reaction protein were lower than those in control group(P<0.05).There were no significant differences in the incidence of adverse drug reactions and ventilator adverse reactions between two groups(P>0.05).Conclusion Titropium bromide in the treatment of AECOPD complicated with acute respiratory failure can significantly improve the curative effect,improve pulmonary function and arterial blood gas,but attention should be paid to the timely treatment of adverse reactions of dry mouth.

Objective:To investigate effects of short-term cigarette smoke exposure combined with poly(I:C)stimulation on lung immune response and interferon expression in mice.Methods:BALB/c mice were randomly divided into 4 groups:control group,smoke group,poly(I:C)group and smoke combined poly(I:C)group.Total cell number and cell classification count of bronchoalveo-lar lavage fluid(BALF)were detected,and cell morphology was observed under ordinary light.Cytokines,chemokines,interferon and interferon stimulating genes expressions in lung tissues were detected by fluorescence quantitative PCR.Results:Compared with control group,total cell count,macrophage count and neutrophil count in smoke combined poly(I:C)group were significantly increased(P<0.05),and macrophage count was higher than that in poly(I:C)group.Macrophages of airway lavage fluid of mice in smoke combined with poly(I:C)group were larger in size,round or irregular in shape,and had more vacuoles in cytoplasm.Com-pared with control group,mRNA expressions of neutrophil chemokine CXCL1(P<0.05),CXCL2(P<0.01)and lymphocyte chemo-kine CCL2(P<0.01)in lung tissues of mice in smoke combined with poly(I:C)group were increased.IL-1β,IL-6,TNF-α mRNA expressions were significantly increased(P<0.01),IFN-β(P<0.01),IFN-γ(P<0.05),MX2(P<0.01)and IP-10(P<0.01)expre-ssions in lung tissues were significantly increased,and compared with poly(I:C)group,mRNA expressions of CXCL2(P<0.05),TNF-α(P<0.01)and IFN-β(P<0.05)in lung tissues of mice in smoke combined with poly(I:C)group were significantly increased.Conclusion:Cigarette smoke combined with poly(I:C)induces lung inflammation and expressions of interferon and interferon stimu-lating genes in mice.Cigarette exposure also increases poly(I:C)-induced acute lung inflammation and type Ⅰ interferon expression in mice.

Objective:To evaluate the relationship between pelvimetric parameters and surgical difficulty in robot-assisted total mesorectal excision (TME) performed by experienced colorectal surgeons, and to build a nomogram model.Methods:This was a retrospective observational study. The inclusion criteria were as follows: (1) tumor within 10 cm of the anal verge; (2) cancer confirmed by pathological examination of the postoperative specimen; (3) preoperative complete magnetic resonance imaging (MRI) data available; (4) depth of tumor invasion T1-3; (5) circumferential resection margin assessed as negative by MRI; and (6) R0 resection achieved. The exclusion criteria comprised (1) history of pelvic fractures; (2) history of pelvic surgery; and (3) emergency required because of tumor-related intestinal obstruction and/or perforation. Application of above criteria yielded 82 patients who had undergone robot-assisted total mesorectal excision of mid and low rectal cancer in the Department of Colorectal Surgery of the First Affiliated Hospital of Zhengzhou University from January 2021 to December 2022 (modeling group). Additionally, data of 35 patients with mid and low rectal cancer who had undergone robotic-assisted TME at the same center in 2023 January–August were collected for validation of the model (validation group). The following 13 pelvic parameters were studied: pelvic inlet diameter, pelvic outlet diameter, pubic tubercle height, sacral height, sacral depth, interspinous distance, inter-tuberosity distance, lateral mesorectal span, anterior-posterior mesorectal span, anterior mesorectal thickness, posterior mesorectal thickness, rectal area, and mesorectal area. Operating time was used as an indicator of the degree of surgical difficulty, this being defined as the time from the start of skin incision to the end of abdominal closure. Variables related to the duration of surgery were subjected to univariate and multivariate logistic regression analyses to identify factors associated with the difficulty of TME, after which a nomogram for predicting the difficulty of the procedure was established. We constructed receiver operating characteristic and calibration curves to validate the predictive power of nomogram. Furthermore, data from the validation group were used for external validation of the model.Results:The model group comprised 82 patients, including 54 men and 28 women of median age 61.0 years. The median body mass index (BMI) was 23.7 kg/m 2, median distance between the tumor and anal verge 6.1 cm, and median tumor diameter 4.5 cm. Fourteen of these patients had received preoperative adjuvant therapy and 12 had a history of abdominal surgery. There were 35 patients (24 men and 11 women) of median age 64.0 years in the validation group. Their median BMI was 23.7 kg/m 2 and median distance between the tumor and anal verge 6.3 cm. Multivariable analyses of the model group showed that BMI (OR=1.227, 95%CI: 1.240–1.469, P=0.026), distance between the tumor and anal verge (OR=0.733, 95%CI: 0.562–0.955, P=0.022), and interspinous distance (OR=0.468, 95%CI: 0.270–0.812, P=0.007) were independent predictors of surgical difficulty. We then built and validated a predictive nomogram based on the above three variables (AUC=0.804, 95%CI: 0.707–0.900). Calibration curves showed that the S:P in this model was 0.987 and the C-index 0.804. Area under the receiver operating characteristic curve of the predictive model in the validation dataset was 0.767 (95%CI: 0.606–0.928). Conclusion:MRI-based measurements of pelvic parameters are associated with difficulty of performing robot-assisted TME for mid and low rectal cancer. Our nomogram model constructed based on measurements of pelvic parameters has a good predictive ability.
