Objective:To understand the status of continuing care needs of patients with cleft lip and palate after discharge, and to analyze the influencing factors.Methods:Using convenience sampling method, 401 patients with cleft lip and palate and their nursing families who underwent sequential treatment of cleft lip and palate in Peking university hospital of stomatology from April to August 2021 were selected as the research objects. The general information questionnaire and self-made continuous nursing needs assessment table were used to investigate patients with cleft lip and palate current situation of continuous nursing needs and analyze the influencing factors.Results:The total score of continuing care needs of patients with cleft lip and palate was (91.53±12.07). From high to low, the demand dimensions were health promotion demand, disease self-care demand, doctor-patient communication demand and psychosocial support demand. The results of multivariate linear regression analysis showed that the mode of payment, the number of operations, the intention of rehabilitation guidance, the mode of continuation service and the expected continuation service cycle were the influential factors for the continuing nursing needs of patients with cleft lip and palate ( R2=0.282, F=27.16, P<0.05). Conclusion:Patients with cleft lip and palate have a high demand for continuing nursing. Individualized and effective continuous nursing intervention measures should be developed according to the needs of patients to promote the rehabilitation of patients.

Objective To explore the proprioception characteristics of knee joints for knee osteoarthritis (KOA) patients before unicondylar knee arthroplasty (UKA) and total knee arthroplasty (TKA). Methods Twenty-nine single-compartment KOA patients were selected. Fifteen patients were treated with UKA (UKA group) and fourteen patients were treated with TKA (TKA group). The test was performed 1 to 3 days before the operation.The keen society scores (KSS) of KOA patients in UKA group and TKA group were compared, and their joint position sense and kinesthesia were compared with control group. Results Significant differences in KSS were found in TKA group and UKA group, and the knee joint position sense and kinesthesia showed no significant differences between TKA group and UKA group.There were no significant differences in the knee joint position sense and kinesthesia between the operated leg and unoperated leg in TKA group and UKA group, and between the left leg and right leg in control group. Compared with control group, there were significant differences between UKA group and TKA group in 60° position sense of the operated leg and unoperated leg.The kinesthesia of the operated leg and unoperated leg in UKA group and TKA group were also significantly different from that in control group. Conclusions Compared with control group, the proprioception of the knee joint in KOA patients was significantly reduced before the surgery, but the characteristics of proprioception in UKA group and TKA group were similar.

Objective: The aim of this study is to discover the possible working mechanisms of Ardisiae Japonicae Herba (AJH) on hepatoma carcinoma (HCC). Methods: In this study, ethanol extract of AJH was prepared and used to treat HCC cell in vitro. Furthermore, a genomic wide RNA sequencing (RNA-seq) was performed to screen deregulated genes in HCC cells after the treatment of AJH extract. The gene and protein expression related to lipid metabolism in HCC cells were also investigated to validate the results obtained from RNA-seq. Results: AJH extract could inhibit HCC cell proliferation in vitro. RNA-seq analysis has identified 1,601 differentially expressed genes (DEGs, fold change ≥ 2.0 or fold change ≤ 0.5, P < 0.05) in HCC after AJH extract treatment, which included 225 up-regulated genes and 1,376 down-regulated genes. KEGG pathway analysis of DEGs demonstrated that lipid metabolism was a potential pathway related to AJH treatment. In agreement with the RNA-seq data, qPCR and Western-blot analysis indicated that expression of genes and proteins related to lipid metabolism (SREBP1, ACC, ACLY and FASN) were significantly down-regulated in AJH treatment group as compared with the control group. Furthermore, AJH extract could also decrease lipid contents and cellular free fatty acid levels in HCC cells. Conclusion: Ethanol extract of AJH could inhibit HCC cell proliferation in vitro, the possible mechanism may be related to the inhibition of lipid metabolism.

Objective:To study the effect of Fushengong prescreption on the regulation-antagonism effect of angiotensin converting enzyme-angiotensin Ⅱ-angiotensin Ⅱ 1 receptor （ACE-AngⅡ-AT1R） axis and angiotensin converting enzyme 2-angiotensin （1-7）-Mas receptor［ACE2-Ang（1-7）-MASR］ axis of rats with chronic renal failure（CRF）， and to explore its mechanism of delaying the development of CRF. Method:The 65 male SD rats were randomly divided into normal group （n=10） and modeling group （n=55）. The normal group was routinely reared， while the modeling group were administered by gavage with 0.25 g·kg^-1d^-1 adenine suspension for 28 days. After the model was successfully established， the survival model rats were randomly divided into model group， benazepril group（0.01 g·kg^-1·d^-1）and low，medium and high dose of Fushengong prescreption groups （4，8，16 g·kg^-1·d^-1）. The normal group and model group were administered the same volume of normal saline by gavage， lasted for 28 days. After the experiment， systolic blood pressure （SBP） and diastolic blood pressure （DBP） of caudal artery were measured， and 24-hour urine was collected to determine 24-hour urine protein （24 h U-pro）. The content of serum creatinine（SCr） and blood urea nitrogen （BUN） in the serum were measured， the histological morphology was observed by hematoxylin eosin（HE）staining， and the degree of renal interstitial fibrosis was observed by Masson staining. Enzyme linked immunosorbent assay （ELISA） was used to determine the contents of AngⅡ， Ang （1-7） and Cystatin C （CysC） in serum and renal homogenate. The protein level of ACE， ACE2， AT1R and MASR were detected by Western blot. The expression of ACE and ACE2 protein in renal tissues were detected by immunohistochemistry. Result:Compared with normal group， the expression levels of SCr， BUN and CysC in model group were significantly increased（P<0.05）， the content of AngⅡ in serum and kidney tissues were significantly increased， the content of Ang （1-7） were significantly decreased（P<0.05）， the expression of ACE and AT1R protein in renal tissues were significantly increased（P<0.05）， and the expression of ACE2 and MASR protein were significantly decreased（P<0.05）. Compared with model group and benazepril group， after the intervention with Fushengong prescreption， the serum SCr，BUN and CysC decreased（P<0.05），the content of AngⅡ in serum and kidney tissues decreased significantly，Ang（1-7） increased significantly（P<0.05）， the expression of ACE and AT1R protein in renal tissues decreased significantly（P<0.05）， ACE2 and MASR protein increased significantly（P<0.05）. The high-dose Fushengong prescreption has the best effect. The high， medium and low-dose effects of Fushengong prescreption were dose-dependent. Conclusion:Fushengong prescreption improved renal function and pathological change of kidney in adenine-induced rats with chronic renal failure. The mechanism may be related to the inhibition of ACE-AngⅡ-AT1R axis and promotion of ACE2-Ang（1-7）-MASR axis ，which leads to the delaying of the progression of chronic renal failure.

Objective:To observe the effects of Fushengong prescription on secretory glycoprotein （Wnt）/β-serial protein （β-catenin） signaling pathway in kidney of rats with chronic renal failure （CRF），and to further explore its mechanism of releasing the aggregation of extracellular matrix（ECM），inhibiting renal tubule interstitial fibrosis （TIF） and prolonging the progression of CRF. Method:A total of 55 SD male rats were randomly divided into the normal group，the model group，and the low， medium and high dose groups of Fushengong prescription，with 11 rats in each group.The normal group was routinely reared and the other 4 groups of rats were used to establish CRF model with 0.5% adenine fodder， fed them continuously for 21 d. After successful modeling，all model rats were switched to conventional feed. Normal saline （NS） was given the normal group and the model group by 20 mL·kg^-1·d^-1， the low， middle and high dose groups rats of Fushengong prescription were given intragastric administration Fushengong prescription according to the body weight of 4， 8， 16 g·kg^-1，once a day，continuous gavage for 30 d. After the experiment，the pathomorphism change of renal tissues of rats was measured by Masson staining， the expression of Wnt4 and β-catenin mRNA in the kidney tissues were observed by the method of Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）， the expression of Wnt4，β-catenin and matrix metalloproteinase-7（MMP-7） protein of renal tissues were detected by the methods of Western blot. The expression of Wnt4， β-catenin protein of renal tissues were detected by the methods of immunohistochemistry （IHC）. Result:Compared with normal group，renal tubule interstitial fibrosis of renal tissues increased distinctly and the expression of Wnt4，β-catenin and MMP-7 protein increased significantly in the model group. Wnt4 and β-catenin mRNA also increased significantly in model group（P<0.01）. Compared with model group， the expression of Wnt4， β-catenin and MMP-7 protein in the Fushengong prescription groups decreased obviously （P<0.05）. The expression of Wnt4 and β-catenin mRNA in Fushengong prescription groups also decreased obviously. Conclusion:The mechanism of Fushengong prescription can release the aggregation of ECM，inhibit TIF and delay the progression of CRF，which may be related with the activation of Wnt/β-catenin signal pathway.
