Objective To investigate the effects of Rosa Laevigata Michx Flavoid( RLMF) and Rosa laevigata Michx Polysaccharose (RLMP) on expression of TRPV5 in IgA Nephropathy (IgAN) rat renal tissue. Methods Forty Sprague-Dawley rats were randomly assigned to four groups.The rat model of IgA nephropathy was induced by intragastric administration of bovine serumalbumin and injections of LPS and CC14.Eight weeks later,the rats with IgAN were treated with RLMF or RLMP (4 weeks), or normal saline.Rats was sacrificed at thirteenth weeks, and RNA was extracted from the kidney.Expression of TRPV5 in tubulointerstitial tissues were analyzed by fluorescent quantitative RT-PCR. Results After RFLP intervention,the expression levels of TRPV5 were markedly increased (P<0.01) than model control group,while decreased (P<0.05) than normal control group but had no significance with model control group after RFLF intervention. Conclusion TRPV5 expression is decreased in IgAN,and RLMP can adjust TRPV5 expression and improve renal function of IgAN.

Real-time fluorescent quantitative PCR was used to examine PGC-1α mRNA expression in brown adipose tissue and skeletal muscle of rats. The results showed that the expression levels of PGC-1α mRNA in brown adipose tissue and skeletal muscle of obese rats were lower than those of the normal ones (all P<0.01). After high dose glucocorticoid treatment, the levels of PGC-1α mRNA expression in brown adipose tissue and skeletal muscle, both in normal and obese rats, were decreased significantly.

Objective To study the effect of the extract of Chrysanthemum Indicum(CI)on the expression of tumor necro-sis factor-α (TNF-α) and neutrophil function in chronic bronchitis (CB)rats and to explore the therapeutic mechanism for chronic bronchitis. Methods The extract of CI was prepared. Wistar rats were randomly divided into blank control group, model group, Chuanxiling group, and low-, middle-and high-dose CI extract groups. Rat model of CB was established by intratracheal injection with low-dose lipopolysaccharide. After drug intervention, the expression of TNF-α in rat serum and bronchoalveolar lavage fluid was detected by ELISA method. Phagocytic function of the neu-trophil and respiratory burst of the rats were measured by flow cytometry (FCM). Results Compared with the blank con-trol group, the phagocytic function of the neutrophil, respiratory burst of the rats, and the expression of TNF-α in rat serum and bronchoalveolar lavage fluid of the model group were increased significantly. CI extract significantly decreased the abnormal rising of the above indexes. Conclusion Down-Regulation of TNF-α expression, and decrease of the neutrophil phagocytic function and rat respiratory burst may be one of the therapeutic mechanisms of Chrysanthemum In-dicum extract for the treatment of CB.

Objective To investigate the prevalence rate of metabolic syndrome (MS) and its related diseases in Bengbu community residents. Methods 3246 residents aged from 25 to 74 years were chosen through cluster random sampling method, including 1459 males and 1787 females. MS and its related diseases were examined. Results (1) The prevalence rate and standardized rate of MS was 20. 5% and 16.0%, respectively, which reached higher level all over China. The prevalence rate of male and female was 22. 9% and 18. 6%, respectively. The highest prevalence rate occurred in presenium patients. (2)The prevalences of various metabolic diseases were increased with aging except for overweigh/obesity and MS (P<0.01). The prevalence of various metabolic diseases was 1 times higher in elderly patients than that in young patients, and the prevalence rate of MS in male and female increased to 2.8 times and 2.7 times, respectively. The prevalence rate of type 2 diabetes mellitus increased biggest, male to 7.9 times and female to 12.8 times compared with the original level. (3) The multiple components clustering rate of MS was high, only 33.8% of individuals had no metabolic disorder. Conclusions The prevalence rates of MS and its related diseases are high in Bengbu community residents. It is necessary to take comprehensive measures to prevent and control MS in community.

Objective To investigate the significance of acute kidney injury biomarkers with calcineurin inhibitors (CNI) related nephrotoxicity in the treatment of refractory nephritic syndrome.Methods Ninety-two patients were included with 59 males and 33 females with average age of (5.67 ± 3.65) years old,who were diagnosed with nephrotic syndrome at Shanghai Children's Hospital from March 2014 to December 2015.66 patients including 44 males and 22 females with mean age of (4.97 ± 3.52) were treated by steroid as the control group and 26 patients including 15 males and 11 females with mean age of (6.59 ± 3.95) were treated by steroid combined with CsA and FK506 as the observation group.The blood,urine samples were collected before drug treatment (0 d) and very early stage of treatment (3 d),early stage (1 month),middle and late stage (3 months and 6 months) as the different observation time points.The change level of neutrophil gelatinase associated lipocalin(NGAL),kidney injury molecular-1 (KIM-1),fibronectin(FN) and tumor necrosis factor-alpha(TNF-α) in serum and urine were detected at different time points to compare with biomarkers such as retinol-binding protein(RBP),N-acetyl-β-D-glucosamccharase(NAG) in urine.Results The serum NGAL(sNAGL) level was more obvious after 6 months of CNI treatment in the observation group than in the control group[(138.00 ±32.49) μg/L vs.(46.54± 11.41) μg/L,t =2.115,P ＜0.05];the level of urine TNF-oα(uTNF-α) was higher obviously after 6 months of CNI treatment in the observation group than in the control group with significant differences [(2.35 ± 0.78) pg/μmol vs.(0.75 ± 0.36) pg/μmol,t =1.840,P ＜ 0.05];the level of urine KIM-1 (uKIM-1) was lower in the observation group than the control group after 3 months treatment of the CNI [(0.15 ± 0.03) ng/μmol vs.(0.33 ± 0.07) ng/μmol,t =-2.077,P ＜ 0.05);the level of urine NGAL (uNGAL) was lower in the observation group than the control group after 3 months treatment of the CNI [(0.09 ±0.03) ng/μmol vs.(0.23 ± 0.04) ng/μmol,t =-2.959,P ＜ 0.05].But the serum TNF-α (sTNF-α),urine FN (uFN),urine RBP(uRBP) and urine NAG (uNAG)did not show any significant change before and after the C NI treatment.Conclusions Compared with other acute kidney injury biomarkers (uNGAL,KIM-1,FN,RBP,and NAG),sNAGL and uTNF-α may be more sensitive to the early evaluation of CNI related nephrotoxicity.The occurrence of CNI related kidney injury shall be watched out at the beginning of 6-month of CNI treatment.

Objective To identify the characteristics of complementary and alternative therapies for cancer patients and investigate the effect on symptom clusters in cancer patients,in order to provide references in management of the symptom clusters.Methods A scoping review was conducted to search nine databases,namely PubMed,Cochrane Library,Web of Science,Embase,PsycINFO,CINAHL,CNKI,Wanfang Data,and VIP,for literatures published between January 2016 and January 2024.Results Twenty articles focusing on complementary and alternative therapies were included.Four themes were identified from the retrieved articles:cancer research subjects,characteristics of complementary alternative therapies,type of symptom cluster and effectiveness of complementary alternative therapies.Specifically,the cancer research subjects in relation to symptom cluster management included those of breast cancer,advanced cancer and the cancer under radio or chemotherapy.The most commonly used types of complementary and alternative therapies in managing the symptom clusters were exercise therapies,cognitive-behavioural interventions,traditional Chinese medicine therapies,multidisciplinary collaborative models and specific interventions.Interventions for symptom clusters predominantly targeted fatigue,mental status,pain,and gastrointestinal symptoms.Conclusion The interventions for symptom clusters in complementary and alternative therapies vary across different types of complementary and alternative therapies,so as the effectiveness.Some of the complementary and alternative therapies have unidentified effects and further investigations are required.The complementary and alternative therapies currently that have been used in managing the symptom clusters were found to have shortcomings.Further studies should focus on sentinel and core symptoms of symptom clusters and emphasize the development of standardised and individualised intervention plans based on symptom management theories,hence to improve the management of symptom clusters in cancer patients.

Since December 2019,severe acute respiratory syndrome coronavirus 2 has been found to be the culprit in the coronavirus disease 2019 (COVID-19),causing a global pandemic.Despite the existence of many vaccine programs,the number of confirmed cases and fatalities due to COVID-19 is still increasing.Furthermore,a number of variants have been reported.Because of the absence of approved anti-coronavirus drugs,the treatment and management of COVID-19 has become a global challenge.Under these circumstances,drug repurposing is an effective method to identify candidate drugs with a shorter cycle of clinical trials.Here,we summarize the current status of the application of drug repurposing in COVID-19,including drug repurposing based on virtual computer screening,network pharmacology,and bioactivity,which may be a beneficial COVID-19 treatment.
