OBJECTIVE To investigate the clinical efficacy of integrating pharmacists into family health teams （FHTs） for long-term medication therapeutical management （MTM） in stroke patients， and empirically evaluate the service model. METHODS A pharmacist team， jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University （hereinafter referred to as “our hospital”）， developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design， 170 stroke patients discharged from our hospital （July 2022-December 2023） and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group （88 cases） and control group （82 cases） according to random number table. The control group received routine FHTs care （without pharmacist involvement in the team collaboration）， while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework， dynamic medication adherence management， medication safety monitoring， a home medication assessment system， and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention， involving medication adherence （adherence rate， adherence score）， compliance rates for stroke recurrence risk factors [blood pressure， low-density lipoprotein cholesterol （LDL-C）]， and incidence of adverse drug reactions （ADR）. RESULTS After 12 months， the trial group exhibited significantly higher medication adherence rates， improved adherence scores， higher compliance rates for blood pressure and LDL-C targets compared to the control group （P＜0.05）. The incidence of ADR in the trial group （4.55%） was significantly lower than that in the control group （8.11%）， though the difference was not statistically significant （P＞ 0.05）. CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence， offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.

Objective To develop a Traditional Chinese Medicine(TCM)syndrome diagnosis scale suitable for evaluating the overall health status of participants in long-term simulated weightlessness experiments,and preliminarily evaluate its reliability and validity.Methods Based on the understanding of the pathogenesis of TCM in different stages of long-term manned spaceflight,a scale was developed through literature research and expert consultation.Test-retest reliability and internal consistency coefficient were used to test the reliability of the scale.Item analysis and factor principal component analysis were used to evaluate the validity of the scale,and a rotating component matrix was used to analyze the correlation between each item and dimension using 36 volunteers in a 90 days head down bed rest experiment as the research subjects.Results The scale contains eight dimensions and 57 items.The reliability analysis showed that the correlation coefficient of the total score of the scale for the first and second tests of 30 participants was 0.889,indicating high stability of the scale.The Cronbach coefficient of the scale was 0.934,indicating very good internal consistency.The split half reliability after correction was 0.858,indicating a high reliability of the scale.The validity analysis showed that the difference between the high score group and the low score one for each of the 57 items was statistically significant(P<0.01),and the Pearson correlation coefficient between each item and the total score of the scale was greater than 0.4(P<0.001).The cumulative contribution rate of 8 common factors extracted using principal component factor analysis was 55.293%,and the results of rotating component matrix analysis,after applying TCM theory and expert feedback,had a coincidence of up to 87.5%with the initial 8 dimensions,indicating good structural validity of the scale.Conclusion The scale has good reliability and validity,and can diagnose TCM syndromes.It is suitable for long-term simulated weightlessness experiment and provides an objective and quantitative new method for evaluating the subjective feelings of participants.

Objective:To establish the normal reference value of left ventricular function parameters by cadmium-zinc-tellurium (CZT) SPECT stress gated myocardial perfusion imaging (G-MPI) in low-likelihood of stable coronary artery disease (SCAD).Methods:From March 2022 to August 2022, 348 consecutive SCAD patients (146 males, 202 females, age (58±10) years) who underwent exercise or pharmacological stress G-MPI (CZT SPECT) in Beijing Anzhen Hospital, Capital Medical University were retrospectively recruited. Left ventricular end-diastolic volume (EDV), end-systolic volume (ESV), and left ventricular ejection fraction (LVEF) were acquired using quantitative gated SPECT (QGS) analysis. EDV and ESV were corrected by body surface area (BSA) to obtain EDV index (EDVI) and ESV index (ESVI), respectively. Independent-sample t test, one-way analysis of variance and Mann-Whitney U test were used for data analysis. The influences of EDV, ESV, EDVI, ESVI and LVEF were analyzed by multiple regressions for linear models. Results:There were 314 patients with low-likelihood of SCAD (128 males, 186 females, age (58±10) years) and 34 normal controls (18 males, 16 females, age (55±10) years). There were no significant differences of basic clinical characteristics and left ventricular function parameters in different genders between 2 groups ( z values: from -1.74 to -0.02, t values: from -1.16 to 1.17, all P>0.05). Using the 95% CI as the cut-off value for left ventricular function parameters in patients with a low-likelihood of SCAD, the upper limits of EDV, ESV, EDVI and ESVI in females and males were 84 and 111 ml, 30 and 44 ml, 47 and 54 ml/m 2, 17 and 21 ml/m 2, respectively, and the lower limit of LVEF in females and males were 58% and 55%, respectively. In the low-likelihood of SCAD group, the EDV ((58±13) vs (77±17) ml) and ESV ((16±7) vs (26±9) ml) of females were smaller than those of males ( t values: 10.65, 10.35, both P<0.001), while LVEF of females was higher than that of males ((72±7)% vs (67±6)%; t=-6.23, P<0.001). However, there were no significant differences in left ventricular function parameters among different age groups with the same gender ( F values: 0.12-2.19, all P>0.05). Based on multiple regression for linear models, the primary predictors of EDV, ESV and LVEF were gender and weight ( β values: from -0.380 to 0.358, all P<0.05). Conclusions:Normal reference values of left ventricular function parameters are established by CZT SPECT stress G-MPI in low-likelihood of SCAD patients. Left ventricular EDV and ESV of females are smaller than those of males, while LVEF of females is higher than that of males. The influence of gender on left ventricular function parameters should be considered in clinical practice.

Objective:To analyze the epidemiological and clinical characteristics of patients infected by novel coronavirus Omicron variant, and also to analyze whether vaccination against novel coronavirus has an impact on the severity and prognosis of Omicron patients.Methods:A prospective, single-center observational study was conducted to collect data of consecutive patients with Omicron variant infection admitted to the designated hospital for coronavirus disease 2019 (COVID-19) charged by Tianjin COVID-19 rescue medical team of Tianjin Third Central Hospital, from January 8 to February 2, 2022. The clinical characteristics of the patients were analyzed, and the influence of whether the patients were inoculated with booster vaccination on the condition and outcome was analyzed. Data were collected including epidemiological, clinical features, laboratory and imaging examination, treatment measures and clinical outcomes, and difference between groups was analyzed.Results:A total of 362 patients were included, including 136 cases (37.57%) in the booster group, 190 cases (52.49%) in the routine vaccination group, and 36 cases (9.94%) in the unvaccinated group. There was a trend of concentrated distribution of patients, of which 171 cases (47.24%) patients showed family clustering, involving 69 families. Seventy-four cases (20.44%) of the 362 patients had one or more underlying diseases, mainly hypertension (64 cases, 17.68%), diabetes mellitus (23 cases, 6.35%), and coronary heart disease (18 cases, 4.97%); 215 patients (59.39%) had one or more discomfort symptoms, mainly cough (158 cases, 43.65%), pharyngeal discomfort (154 cases, 42.54%) and fever (136 cases, 37.57%). The diagnostic typing was mild type in 194 cases (53.59%), moderate type in 165 cases (45.58%) and severe type in 3 cases (0.83%). The patients had elevated immunoglobulin G (IgG) antibody titers to the novel coronavirus on admission [23.17 (3.08, 60.77)]. Patients were medically isolated and the main treatment measures included traditional Chinese medicine identification (Chinese medicine or tonics) in 265 cases (73.20%), prone treatment in 188 cases (51.93%), anticoagulation with low-molecular heparin in 106 cases (29.28%), immunomodulatory therapy with thymofacine in 21 cases (5.80%), antimicrobial drugs in 20 cases (5.52%), transnasal high-flow oxygen therapy in 12 cases (3.31%), glucocorticoids in 5 cases (1.38%), non-invasive mechanical ventilation in 1 case (0.28%), and invasive mechanical ventilation in 1 case (0.28%). A total of 362 patients were discharged with no deaths, of which 12 patients (3.31%) were admitted to the intensive care unit (ICU). The median duration of illness was 13 (10, 15) days, the median length of hospitalization was 13 (11, 15) days, and the median time to nucleic acid conversion was 13 (10, 15) days. Compared with the unvaccinated group, the IgG antibody titers of patients in the booster and routine vaccination groups [41.49 (20.32, 81.38), 19.94 (2.33, 49.25) vs. 0.16 (0.07, 1.94)] and the proportion of mild patients [66.91% (91/136), 48.94% (93/190) vs. 27.28% (10/36)] were higher, which were also higher in the booster vaccination group than in the conventional vaccination group (all P < 0.05). Compared to the conventional and booster vaccination groups, the unvaccinated group had a higher proportion of severe patients [5.56% (2/36) vs. 0.53% (1/190), 0 (1/136)], longer time to nucleic acid conversion [days: 15 (11, 16) vs.12 (10, 15), 13 (11, 15)], and longer disease duration [days: 15 (11, 16) vs. 12 (10, 15), 13 (11, 15)], and a higher percentage of ICU admissions [16.67% (6/36) vs. 2.63% (5/190), 0.74% (1/136)], with statistically significant differences among the three groups (all P < 0.05). Conclusions:Omicron variant is extremely infectious with aggregated onset, but its clinical symptoms are mild. The vaccine, especially the booster vaccination, remains effective in preventing severe-stage progression and improving prognosis in patients with Omicron variant infection.

Objective:To evaluate the clinical effect of awake prone positioning (APP) for common coronavirus disease 2019 (COVID-19) caused by Omicron variant.Methods:Retrospectively analyze the clinical data of patients with COVID-19 caused by Omicron variant admitted by medical team of Tianjin Third Central Hospital during the period of supporting Tianjin COVID-19 designated hospital from January 8 to February 20, 2022. Patients who met the diagnostic criteria for common COVID-19 and had risk factors for developing severe disease or had pulse oxygen saturation (SpO 2) ≤0.93 after exercise without supplementary oxygen were enrolled. Patients were divided into APP group and control group according to whether they completed the daily 12-hours APP in the first three days after enrollment. Demographic characteristics, clinical symptoms, COVID-19 vaccination status, laboratory examination, disease progression (progression to severe), time to nucleic acid negative conversion, length of hospital stay, and adverse reactions and tolerability [visual analog scale (VAS) score (the higher the score, the worse the tolerability] during APP were evaluated in two groups. Interleukin-6 (IL-6), C-reactive protein (CRP), SpO 2/inhaled oxygen concentration (FiO 2) ratio and ROX index (ROXI) were compared between two groups at enrollment, 3rd and 7th day after enrollment. Results:There were no significant differences in demographic characteristics, clinical symptoms, vaccination rates of COVID-19 and laboratory tests between the two groups. There were no statistically significant differences in IL-6, CRP, SpO 2/FiO 2 ratio and ROXI between two groups at the time of enrollment. Compared with the group at the time of enrollment, SpO 2/FiO 2 ratio and ROXI in APP group increased significantly at the 3rd day after enrollment [SpO 2/FiO 2 ratio: 461.90 (457.10, 466.70) vs. 446.67 (437.14, 457.10), ROXI: 25.40 (23.33, 25.93) vs. 22.57 (21.86, 24.40), all P < 0.05], and the levels of IL-6 and CRP in control group were significantly increased [IL-6 (ng/L): 18.30 (6.50, 37.75) vs. 7.40 (5.10, 11.15), CRP (mg/L): 11.46 (2.11, 17.96) vs. 4.11 (1.72, 9.05), all P < 0.05]. At the 3rd day of enrollment, the levels of IL-6 and CRP in APP group were significantly lower than those in control group [IL-6 (ng/L): 7.35 (4.35, 12.80) vs. 18.30 (6.50, 37.75), CRP (mg/L): 4.52 (1.98, 9.66) vs. 11.46 (2.11, 17.96), all P < 0.05], while SpO 2/FiO 2 ratio and ROXI were significantly higher than those in control group [SpO 2/FiO 2 ratio: 461.90 (457.10, 466.70) vs. 446.67 (441.90, 459.52), ROXI: 25.40 (23.33, 25.93) vs. 23.31 (22.10, 24.66), all P < 0.05]. At the 7th day of enrollment,there were no significant differences in IL-6, CRP, SpO 2/FiO 2 ratio and ROXI between two groups. There were no severe cases in both groups. The time of nucleic acid negative conversion and length of hospital stay in APP group were significantly shorter than those in control group [10.0 (8.0, 12.0) days vs. 11.0 (9.0, 13.0) days, 12.0 (10.0, 14.0) days vs. 14.0 (12.0, 16.0) days, respectively, all P < 0.05]. The main adverse reaction during APP was back pain, and the incidence in APP group was slightly lower than that in control group, but the difference was not statistically significant [17.9% (17/95) vs. 26.5% (27/102), P = 0.149]. VAS score in control group was significantly higher than that in APP group [score: 2.5 (2.0, 4.0) vs. 2.0 (1.0, 3.0), P = 0.004]. Conclusions:In common COVID-19 patients caused by Omicron variant with high risk factors for progression to severe disease or decreased oxygen reserve capacity, early APP can shorten the time of nucleic acid negative conversion and the length of hospital stay, but its effect on preventing disease progression cannot be determined.

OBJECTIVE：To study the effects of augmented renal clearance （ARC）on blood trough concentration of patients receiving high-dose regimen of teicoplanin. METHODS ：Patients who received high-dose regimen of teicoplanin in the ICU were prospectively collected from the Affiliated Suzhou Hospital of Nanjing Medical University/Suzhou Municipal Hospital during Jul. 2018-Jun. 2020. They were divided into ARC group and normal renal function group according to corrected creatinine clearance. The dosage regimen of teicoplanin in the two groups were loading dose of 600 mg，q12 h×3 doses，maintenance dose of 6-10 mg/kg，qd，and the dosage was adjusted in combination with creatinine clearance rate and blood trough concentration. The trough concentration of blood samples which were collected 30 min before the 4th and 8th-10th dosage of teicoplanin were determined by HPLC. Trough concentration ，clinical efficacy ，Gram-positive bacterial clearance rate and the occurrence of ADR were compared between 2 groups. RESULTS ：A total of 56 patients were included and divided into ARC group （18 cases）and normal renal function group （38 cases）. ARC group had younger age （P＜0.001）and lower serum albumin level （P＝0.025）than normal renal function group. The trough concentrations before administration of the 4th and 8th-10th dosage in ARC group were lower than normal renal function group （P＝0.034；P＝0.035）. The trough concentrations in the ARC group and normal renal function group before 8th-10th dosage were all higher than 30 min before the 4th dosage （P＝0.003；P＜0.001）. The clinical efficacy rate and the clearance rate of Gram-positive bacteria in ARC group were 77.8％ and 76.2％，which were lower than those of the normal renal function group ，but there was no statistical difference （P＝0.195；P＝0.223）. There was no liver function damage ，hemocytopenia and allergic reaction in both groups ，but in the normal renal function group ，the causal relationship between acute renal damage and teicoplanin was assessed as “very likely ”in one patient. CONCLUSIONS ：ARC patients are younger ，most of them have hypoproteinemia，and the blood trough concentrations of teicoplanin in high-dose regimen are significantly lower than those of normal renal function patients. For critical ill ARC patients ，it is advisable to increase the loading dose of teicoplanin to make the trough concentration reach the target concentration range quickly.

Objective:To investigate the protective effect of insulin on burn serum-challenged cardiomyocytes in vitro. Methods:Primary culture of cardiomyocytes from Sprague-Dawley (SD) 2-day-old neonate rats were divided into Sham group, burn group, insulin group, and insulin activation inhibitor LY294002 pretreatment group (LY group). The model of cardiomyocytes injury induced by burn serum of 3-month-old SD rats [the serum of abdominal aortic was collected at 6 hours after modelling 30% total surface area (TBSA) Ⅲ degree scald rat] was reproduced. In the insulin group, 10% burn serum and insulin (10 U/L) were added into cell culture medium, and in the LY group, LY294002 (50 μmol/L) was pretreated for 30 minutes before the addition of burn serum and insulin. Sham group was only given 10% serum of sham injured rats (sham rats were only placed in 37 ℃ warm water). After the cells were cultured for 12 hours, the release of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and creatine kinase (CK) were determined by enzyme-linked immunosorbent assay (ELISA). The cardiac troponin T (cTnT) protein expression was examined by Western Blot. Apoptosis of cardiomyocytes was observed after Hoechst 33258 staining.Results:Compared with the Sham group, the cardiomyocytes were damaged and released inflammatory cytokines after burn serum-challenged. The levels of TNF-α, IL-6 and CK increased [TNF-α (ng/L): 273±48 vs. 21±6, IL-6 (ng/L): 416±83 vs. 44±11, CK (U/L): 1.44±0.24 vs. 0.14±0.08, all P < 0.01], while the expression of cTnT protein decreased (cTnT/β-actin: 0.12±0.04 vs. 0.86±0.34, P < 0.01), and the cardiomyocyte apoptosis increased [(19.1±5.6)% vs. (5.2±1.3)%, P < 0.01]. Insulin could significantly reduce the damage of cardiomyocytes, decrease the release of TNF-α, IL-6 and CK induced by burn serum [TNF-α (ng/L): 105±37 vs. 273±48, IL-6 (ng/L): 176±77 vs. 416±83, CK (U/L): 0.82±0.26 vs. 1.44±0.24, all P < 0.05], the expression of cTnT protein significantly increased (cTnT/β-actin: 0.41±0.16 vs. 0.12±0.04, P < 0.05), and the cells apoptosis rate significantly decreased [(10.7±3.2)% vs. (19.1±5.6)%, P < 0.05]. Further blocking experiments showed that LY294002 could mitigate the protective effects of insulin. Conclusion:For cardiomyocytes challenged by burn serum, insulin may decrease inflammation, apoptosis and then protect the cardiomyocytes.

Objective: To analyze the differentially expressed genes related to the chemosensitivity with the TPF regimen for hypopharyngeal squamous cell carcinoma and to measure potential functional targeting genes expressions. Methods: Twenty-nine patients with primary hypopharyngeal cancer who underwent induction chemotherapy with TPF from January 2013 to December 2017 in Beijing Tongren Hospital were enrolled for microarray analysis, including 28 males and 1 female, aged from 43 to 73 years old. Among them, 16 patients were sensitive to chemotherapy while 13 patients were non-sensitive. Illumina Human HT-12 Bead Chip was applied to analyze the gene expressions and online bioinformatics analysis was used to analyze the differentially expressed genes. Reverse transcription and quantitative real-time PCR (RT-qPCR) was used to measure the mRNA expression of potential functional genes of TPF induction chemotherapy in 43 samples, 29 from original patients and 14 from additional patients. Graphpad prism 7.0 software was used for statistical analysis. Results: A total of 1 381 significantly differentially expressed genes were screened out. By GO analysis, up-regulated genes included sequestering in extracellular matrix, chemokine receptor binding and potassium channel regulator activity; down-regulated genes included regulation of angiogenesis, calcium ion binding and natural killer cell activation involved in immune response. With KEGG database analysis, down-regulated pathways included ECM-receptor interaction and peroxisome and up-regulated pathways included Glutathione metabolism and PPAR signaling pathway. The expressions of CD44 and IL-6R were significantly different and appeared biologically significant. CD44 was significantly upregulated in insensitive tissues (0.54±0.06) compared with sensitive tissues (0.33±0.04)(P<0.01). IL-6R was significantly downregulated in insensitive tissues (0.44±0.03) compared with sensitive tissues. (0.68±0.03) (P<0.01). Conclusion CD44 and IL-6R may be potentially functional genes of TPF induction chemotherapy in hypopharyngeal squamous cell carcinoma.

Objective:To evaluate the application of computer-assisted design and three-dimensional printing technique in reconstruction of maxillary defects with individual free fibular flap.Methods:A total of 13 patients, 7 males and 6 females with age from 12 to 55 years old, underwent the reconstruction of maxillary defects after subtotal or total maxillectomy for benign or malignant tumors between January 2016 and December 2018 were reviewed. Ther were 4 cases of subtotal maxillectomy and 9 cases of total maxillectomy. Before operation, osteotomy line was planned on three-dimensional images. A three-dimensional individual resin fibula model based on mirror images of the healthy side maxilla was obtained to fabricate an anatomically adapted osteomyocutaneous fibula free flap using computer-assisted design and forming. Oral, nasal, and eye functions and facial appearance were evaluated.Results:The 13 cases were followed up for 5-40 months, all flaps were alive except one due to flap failure and all cases were tumor free confirmed by CT or MRI. Ten patients could eat normal food without nasal food return, and 3 cases had palatal fistula. Eleven cases showed good speaking functional results. All cases had normal eye positions, no cases with diplopia and loss of vision. With evaluation by VAS, an average score of 8 was obtained, and most of patients were satisfied with their postoperative facial appearances.Conclusion:Reconstruction of maxillary defects by free fibular flap designed by three-dimensional printing and computer-assisted technique not only restored oral, nasal and eye functions, but also showed satisfactory facial appearance.

Objective:To evaluate clinical applications and efficacy of submental artery perforator flap in reconstruction surgery after removal of pharyngeal carcinoma.Methods:A total of 27 patients in the Department of Otorhinolaryngology Head and Neck Surgery, Beijing Tongren Hospital, Capital Medical University were included, 23 males and 4 females with age from 40 to 70 years old, and 17 patients were hypopharyngeal carcinoma (HPC) and 10 patients were oropharyngeal carcinoma (OPC). All patients underwent tumor resection followed by simultaneously reconstruction surgery using submental artery perforator flap between January 2015 and December 2019. Of 5 patients with palatine tonsil cancer, 4 underwent the combined approach of neck and oral resection and 1 with madibulotomy. All 5 patients with tongue base cancer received transhyoid partial glossotomy with or without partial laryngectomy. Sixteen patients with pyriform sinus carcinoma received partial laryngo-pharyngectomy with preservation of laryngeal functions. One patient with posterior hypopharyngeal wall carcinoma had partial pharyngectomy. Prognosis and laryngeal functions were analyzed after reconstruction surgery with submental artery perforator flap in patients with pharyngeal carcinoma.Results:The 27 patients were followed up for 6-66 months, with a median of 13 months, of them 24 patients were alive without recurrence or metastasis, 1 patient died of recurrence, 1 patient died of esophageal carcinoma and 1 patient was alive with the recurrence of tongue base carcinoma. Postoperative complications included flap failure for 1 case, pharyngeal fistula for 1 case, subcutaneous hydrops for 2 cases and lymphatic fistula for 1 case. Total 2 and 3 year survival rates were 92.9% and 88.9%, respectively. Total decanulation rate was 92.6%; decanulation rate and intubation time were 16/17 and 3.5 months in HPC patients; and decanulation rate and intubation time were 9/10 and 2 months in OPC patients. Total oral feeding rate was 92.6% and nasogastric feeding time was 3.5 weeks in HPC patients and 3 weeks in OPC patients.Conclusion:The submental artery perforator flap is an excellent choice for reconstruction surgery after removal of oropharyngeal and hypopharyngeal carcinoma, with good outcomes of laryngeal functions.
