OBJECTIVE To explore the effects of multi-disciplinary comprehensive management team of tertiary hospital collaborated with the pharmacists from community health service center （hereinafter referred to as “community pharmacists”） on elderly patients with hypertension in the community. METHODS Elderly patients with hypertension from May 2020 to May 2021 in Yuhua Community Health Service Center of Nanjing were divided into control group （76 cases） and observation group （76 cases） according to the management style. The control group was treated with regular community medical services and the observation group received regular community medical services plus pharmaceutical care provided by the comprehensive management team collaborated with community pharmacists. The compliance， blood pressure control status and hypertension-related complications were compared between 2 groups before management and after 24 months of management. RESULTS After 24 months of management， the compliance and blood pressure compliance rates in both groups were higher than before management； meanwhile， the observation group was significantly higher than control group at the corresponding period （P＜0.05 or P＜ 0.01）. The blood pressure levels of both groups were significantly lower than before management， and the systolic blood pressure as well as the incidences of the whole complications and cerebrovascular injury in the observation group were significantly lower than control group at the 583867635@qq.com corresponding period （P＜0.05）. There was statistical significance in the effects of the rate of reaching the standard of blood pressure on the complications （P＜0.01）. CONCLUSIONS The hypertension management mode of comprehensive management team collaborated with community pharmacists can significantly improve the compliance and blood pressure compliance rate of elderly patients with hypertension， and reduce the incidence of hypertension-related complications.

Objective:To investigate the relationship between intestinal flora and acute respiratory distress syndrome in patients with severe acute pancreatitis.Methods:One hundred and six patients with severe acute pancreatitis admitted to a hospital from March 2019 to February 2021 were selected as the observation group for prospective analysis. They were divided into concurrent group (52 cases) and non-concurrent group (54 cases) according to whether they were complicated with acute respiratory distress syndrome. In addition, 100 healthy people in the same period were selected as the control group to analyze the relationship between intestinal flora and acute respiratory distress syndrome in patients with severe acute pancreatitis.Results:There were significant differences in the number of intestinal flora ( Lactobacillus, Bifidobacterium, Escherichia coli) between the observation group and the control group ( t = 49.69, 73.28 and 46.32; P<0.05). There were significant differences in the number of intestinal flora ( Lactobacillus, Bifidobacterium, Escherichia coli) between the concurrent group and the non-concurrent group ( t = 34.85, 39.71 and 23.47; P<0.05). The levels of serum endotoxin, diamine oxidase and D-lactic acid in the concurrent group were significantly higher than those in the non-concurrent group: (0.63 ± 0.16) EU/ml vs. (0.45 ± 0.08) EU/ml, (6.29 ± 1.18) U/ml vs. (4.89 ± 0.91) U/ml, (11.63 ± 2.84) mmol/L vs. (9.33 ± 2.61) mmol/L ( t = 7.37, 6.85 and 4.34, P<0.05). Spearman analysis showed that severe acute pancreatitis complicated with acute respiratory distress syndrome was negatively correlated with the number of intestinal Lactobacillus and Bifidobacterium ( r = - 0.342 and - 0.291, P = 0.011 and 0.021), which was positively correlated with the number of intestinal Escherichia coli flora ( r = 0.263, P = 0.033). Conclusions:Intestinal colony imbalance is common in patients with severe acute pancreatitis, and the imbalance of intestinal colony and the impairment of intestinal mucosal barrier function are more serious in patients with acute respiratory distress syndrome. There is a significant correlation between severe acute pancreatitis complicated with acute respiratory distress syndrome and its intestinal colony.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

ObjectiveTo observe the effect of Feiyanning prescription （FYN） on cisplatin （DDP） resistance in non-small cell lung cancer （NSCLC） and explore the underlying mechanism. MethodCell counting kit-8 （CCK-8） assay was used to detect the proliferation of A549 and A549/DDP （DDP-resistant） cells treated by DDP （0， 2.0， 4.0， 6.0， 8.0， 10.0 mg⋅L^-1） and the proliferation of A549/DDP cells treated by FYN （0， 100， 200， 300， 400， 500， 600 mg⋅L^-1）. Based on immunofluorescence staining and Western blot （WB）， the expression of epithelial mesenchymal transition （EMT）-related proteins in A549 and A549/DDP groups was observed. A549/DDP cells were classified into control group， FYN group （200 mg⋅L^-1）， DDP group （6.0 mg⋅L^-1）， and combination group ［FYN （200 mg⋅L^-1） + DDP （6.0 mg⋅L^-1）］ and respectively treated with corresponding drugs. Then， invasion ability of each group was examined by transwell assay， and the expression of EMT-related proteins in each group by WB. Moreover， real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） and immunofluorescence staining were separately applied to detect the mRNA and protein expression of drug resistance-related factors in each group， respectively. ResultCompared with A549 group， A549/DDP group showed high resistance to DDP （P<0.01）， low expression of E-cadherin， and high protein expression of Vimentin， N-cadherin， and Snail （P<0.05， P<0.01）. As compared with the control group， FYN inhibited the proliferation of A549/DDP cells in a concentration-dependent manner （P<0.01）， and the FYN group， DDP group， and combination group demonstrated low invasion ability （P<0.01）. In addition， the invasion ability in the combination group was particularly lower than that in the DDP group （P<0.01）. The expression of E-cadherin protein was higher and the protein expression of N-cadherin， Vimentin， and Snail was lower in the in FYN group than in the control group （P<0.01）. The protein expression of E-cadherin， N-cadherin， and Vimentin was lower and the expression of Snail was higher in the DDP group than in the control group （P<0.05，P<0.01）. The protein expression of E-cadherin， N-cadherin， Vimentin， and Snail in the combination group decreased as compared with that in the control group （P<0.01）. Compared with the DDP alone， the combination raised the expression of E-cadherin and lowered the protein expression of N-cadherin， Vimentin， and Snail （P<0.01）. The protein and mRNA expression of lung resistance-related protein （LRP） and multidrug resistance 1 （MDR1） was lower and the protein and mRNA expression of topoisomerase Ⅱα （TOPO Ⅱα） was higher in the FYN group than in the control group （P<0.01）. The protein and mRNA expression of LRP， MDR1， and TOPO Ⅱα was higher in the DDP group than in the control group （P<0.01）. The expression of LRP protein and mRNA showed no significant variation， but the protein and mRNA expression of MDR1 and TOPO Ⅱα increased in the combination group compared with those in the control group （P<0.01）. Compared with the DDP group， FYN group and combination group showed low protein and mRNA expression of LRP and MDR1 and high protein and mRNA expression of TOPO Ⅱα （P<0.01）. Compared with FYN， the combination elevated the protein and mRNA expression of LRP， MDR1， and TOPO Ⅱα （P<0.01）. ConclusionFYN prescription can reverse the DDP resistance of NSCLC by modulating EMT.

Objective:To investigate the birth weight (BW) of infants born to pregnant women living with human immunodeficiency virus (HIV) and its associated factors, and to provide more evidence for the prevention of mother-to-child transmission (PMTCT) in China.Methods:This study was a retrospective cohort study. Between January 2004 and December 2021, pregnant women living with HIV and their infants in Hubei Province were recruited and followed up, and clinical data were collected through hospital medical records and HIV/acquired immunodeficiency syndrome comprehensive response information management system. The multivariable linear regression was performed on the collected data to investigate associated influencing factors of BW.Results:In total, 531 pregnant women living with HIV (581 pregnancies) and 581 infants were enrolled. Of the 581 infants, 36 were HIV-positive, with a PMTCT rate of 6.2%. The mean BW of the infants was (3 075.0±470.2) gram. Protease inhibitor (PI) based-anti-retroviral therapy (ART) ( β=-0.1, 95% confidence interval ( CI)-188.2 to -37.1, P=0.004), ART in the first trimester( β=-0.1, 95% CI -201.9 to -65.5, P<0.001), infant HIV infection ( β=-0.1, 95% CI -310.4 to -68.2, P=0.002), hepatitis C virus infection ( β=0.1, 95% CI 71.2 to 410.4, P=0.005) and gestational age ( β=0.6, 95% CI 155.9 to 191.5, P<0.001) were associated with decreased BW. Conclusions:While improving the effectiveness of PMTCT for HIV, more attention should be paid to pregnant women who received ART in the first trimester and PI-based ART for preventing lower BW and improving maternal and infantile health.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

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. This review summarizes the latest research progress of organoids of taste buds, esophagi, stomachs, livers and intestines, and prospects future application of organoids.

Objective:We conducted a real-world multi-center clinical study with a large sample size to comprehensively evaluate the performance of three commercial hepatitis C virus (HCV) core antigen assays. The study aimed to evaluate the performance for their use in HCV infection screening, and to provide clues for further improving the sensitivity and specificity of the assays.Methods:Key performance indicators including the lower limit of detection (LOD), diagnostic sensitivity, and specificity of three HCV antigen assays (the Architect, Laibo, and ChemClin HCV core antigen assays) were evaluated using commercial seroconversion panels reflecting early HCV infection and clinical routine serum samples of outpatients and inpatients from 3 tertiary hospitals from January 2018 to April 2022. Factors that affect the performance indicators were further investigated.Results:The window period for detecting HCV infection with the three antigen assays was equal to or slightly longer than that of the RNA assay, but all are shorter than that of the anti-HCV assay. There was a good linear positive correlation between HCV core antigen and HCV RNA levels in treatment naive patients with hepatitis C ( r=0.90, P<0.01). For the most common genotype 1b strain in China, the LOD of the three HCV assays were equivalent to 531 IU/ml (Architect), 3,698 IU/mL (Laibo), and 4,624 IU/mL (ChemClin) HCV RNA, respectively. Due to the skewed distribution of HCV RNA levels in treatment-naive hepatitis C patients, more than 95% of the patients had viral loads higher than 6 166 IU/ml. Therefore, the three HCV antigens assays still maintained a satisfactory diagnostic sensitivity (94.33%-99.40%). Among 54 immunodeficient patients (leukemia patients) with HCV infection, 9% (5/54) had negative anti-HCV results, while the HCV antigen assays found all these infectors. Through further experiments, we revealed the amino acid polymorphism in the core region of genotype 3 strain impaired the sensitivity of all three HCV antigen assays. In addition, the sensitivity of the two domestic assays was impaired by anti-HCV antibodies in the serum. The specificity of HCV antigen assays for diagnosing hepatitis C is 99.94% to 99.98%. The rheumatoid factors, autoantibodies, and other unknown interference substances can lead to a small number of low level, "false positive" antigen results. Conclusions:HCV core antigen assay may be used as a satisfactory approach of infection screening, especially for the immunodeficient patents. However, the sensitivity and specificity of the assays are influenced by multiple factors, which should be further improved.

Objective:To investigate the effects of mixed probiotics on food allergy and the underlying mechanism.Methods:BALB/c mice on the 15 th day of pregnancy were randomly (random number table method) classified into the control group, food allergy model group and mixed probiotics group.Mice in the food allergy model and mixed pro-biotics group were subjected to ovalbumin (OVA) sensitization after birth, and those in the mixed probiotics group were then given probiotic solution by gavage from day 21 to day 35.Mice in control group were similarly given 9 g/L saline.Twenty-four hours after the last OVA sensitization, intestinal histopathological sections were prepared to observe intestinal pathological changes.Blood smears were prepared to detect eosinophil count.In addition, serum samples were collected to measure cytokine levels and OVA specific antibodies.The number of dendritic cells (DCs) and regulatory T cells (Tregs) in mouse mesenteric lymph nodes was calculated.Differences among 3 groups were compared by the One- Way ANOVA or Kruskal- Wallis H test. Results:Compared with those of food allergy model group, diarrhea score, the ratio of eosinophils and serum levels of interleukin(IL)-4, IL-5, IL-13, mast cell protease 1 (MCPT-1), and OVA specific antibodies IgE and IgG were significantly lower in mixed probiotics group[(2.00±0.71) points vs.(3.22±0.97) points, (2.28±1.61)% vs.(10.99±2.26)%, (413.68±22.81) ng/L vs.(708.78±27.66) ng/L, (36.64±3.74) ng/L vs.(46.05±4.95) ng/L, (201.37±65.61) ng/L vs.(495.22±96.66) ng/L, (31 924.15±1 177.77) ng/L vs.(36 175.77±618.29) ng/L, (9.10±8.08) ng/L vs.(19.69±0.84) ng/L, (30.50±8.81) ng/L vs.(190.32±6.40) ng/L], while IL-10 level was significantly higher[(164.12±3.88) ng/L vs.(123.90±7.31) ng/L] ( t=3.37, 8.72, 16.07, 3.90, 7.40, 7.95, 3.91, 44.00 and 7.76, respectively, all P<0.01). Compared with those of food allergy model group, programmed cell death ligand 1 (PD-L1) level on the surface of CD 103+ DCs and CD 103+ CD 80-CD 40-DCs, the proportion of Tregs in CD4 + T cells, and the level of programmed cell death 1 (PD-1) on the surface of Tregs were significantly higher in mixed probiotics group[(75.59±0.45)% vs.(45.60±4.73)%, (67.56±1.87)% vs.(37.12±6.07)%, (8.24±0.69)% vs.(6.20±0.66)%, (11.25±3.12)% vs.(4.08±2.33)%]( t=7.88, 4.48, 3.63 and 3.71, all P<0.01). Conclusions:Mixed probiotics can alleviate the symptoms of food allergy and inflammatory response of young rats through mediating Tregs via the PD-1/PD-L1 pathway.

In recent years, it is noted clinically that the low level of serum uric acid is closely related to the adverse outcomes of cardiovascular and cerebrovascular diseases. Recent studies have shown that low uric acid levels not only boost the incidence of arrhythmia and cardiovascular events, but also increase mortality. It also has adverse effects on the development and prognosis of cerebrovascular diseases, including intracerebral hemorrhage and stroke. This article reviews research advances in the adverse effects of low uric acid on cardiovascular diseases andcerebrovascular diseases.
