Objective　This study aims to investigate and compare the clinical characteristics and prognostic factors among primary liver cancer (PLC) patients who had hepatitis B virus (HBV)-induced cirrhosis associated with liver cancer, alcoholic cirrhosis associated with liver cancer, or both HBV and alcoholic cirrhosis associated with liver cancer. 　　　Methods　Inpatients diagnosed with PLC admitted to the First Affiliated Hospital of Fujian Medical University between January 2010 and September 2020 were enrolled and divided into three groups based on the etiology. The follow-up period ends in October 2024. Survival analyses were performed using Kaplan-Meier curves, univariate analysis, and multivariate Cox regression. Results　During the study period, 45 cases of alcoholic cirrhosis associated liver cancer (ALD group), and 71 cases of hepatitis B combined with alcoholic cirrhosis associated liver cancer (HBV+ALD group) were enrolled. At the same time, 73 patients with hepatitis B cirrhosis associated liver cancer (HBV group) during the same period were randomly selected with a ratio of about 1∶1.5, totaling 189 cases. And 183 (96.8%) of the patients were male and 6 (3.2%) were female. The age was (55.93±10.20) years. 109 deaths (57.7%) were recorded. The median survival times were 12 months for the entire cohort, 55 months for HBV group, 36 months for ALD group and 11 months for HBV+ALD group. And the 10-year death rate was 42.5% in HBV group, compared to 66.7% in ALD group and 67.6% in HBV+ALD group. In this study, 93 patients chose either the surgical resection or the radiofrequency ablation as their treatments. The recurrence rate was 69.9%, the median recurrence time was 8 months and the median overall survival time was 39 months. Univariate Cox regression identified that etiology of HBV and ALD, alpha-fetoprotein (AFP)>1 200 ng/mL, Child-Pugh class B and C, Barcelona Clinic Liver Cancer (BCLC) stages of C and D and curative therapies such as surgery and radiofrequency ablation were significantly correlated with overall survival (all P<0.05). Multivariate Cox regression revealed that patients with both HBV and ALD (HR=1.750，95%CI: 1.107-2.765，P=0.017), AFP>1 200 ng/mL (HR=1.649，95%CI: 1.060-2.564，P=0.027), and BCLC stages of C and D (HR=3.404，95%CI: 2.254-5.142，P<0.001) were independent risk factors of mortality in PLC patients with cirrhosis. Conclusions　Among HBV, ALD and HBV+ALD groups, the HBV+ALD group had the shortest median survival time and the highest overall mortality rate, suggesting that alcohol consumption and HBV infection may accelerate the progression of PLC with cirrhosis and worsen its prognosis. HBV infection combined with alcoholic consumption, AFP>1 200 ng/mL, and BCLC stages of C and D were independent risk factors for mortality in PLC patients with cirrhosis.

OBJECTIVE: To observe the clinical efficacy of acupuncture based on "status-target coherence" theory combined with Kegel exercises for vaginal laxity syndrome (VLS). METHODS: Sixty-six patients with VLS were randomized into an observation group (33 cases, 2 cases dropped out, 1 case was discontinued) and a control group (33 cases, 5 cases dropped out). The observation group was treated with acupuncture combined with Kegel exercises, acupuncture was applied to bilateral Ciliao (BL32), Zhongliao (BL33), Sanyinjiao (SP6), etc. The control group was treated with Kegel exercises. Both acupuncture and Kegel exercises were performed once every other day, three times a week for 12 weeks. Before and after treatment, the vaginal laxity questionnaire (VLQ) score, pelvic floor muscle strength (vaginal resting pressure, vaginal systolic pressure, vaginal contraction duration), degree of vaginal laxity and sexual satisfaction questionnaire (SSQ) grade were observed in both groups. RESULTS: After treatment, the VLQ score, vaginal resting pressure, vaginal systolic pressure, vaginal contraction duration in the observation group were elevated compared with those before treatment (P<0.05), and SSQ grade was improved (P<0.05); and the above indexes in the observation group were better than those in the control group (P<0.05). There were no significant difference before and after treatment in the degree of vaginal laxity in the two groups (P>0.05). CONCLUSION Acupuncture based on "status-target coherence" theory combined with Kegel exercises can effectively enhance the strength of pelvic floor muscles, improve the symptoms of vaginal laxity, and improve the satisfaction of sexual life, and its therapeutic effect is better than Kegel exercises alone.

Human keratinocyte growth factor-1 (hKGF-1), a member of the fibroblast growth factor (FGF) family, plays crucial roles in organ development, cell proliferation, wound healing, and tissue repair, representing one of the most effective and specific growth factors for skin repair. However, obtaining recombinant hKGF-1 remains challenging due to its universally low expression efficiency in vitro. This study employs the Bombyx mori baculovirus expression system to establish a technological platform that utilizes the economically important insect Bombyx mori as a bioreactor for high-efficiency and low-cost expression and production of recombinant human keratinocyte growth factor 1 (hKGF-1) protein, ultimately achieving high-level expression of hKGF-1 in Bombyx mori ovary cell line (BmN). In this study, we optimized the hKGF-1 sequence based on the codon preference of baculovirus. By fusing hKGF-1 with polyhedrin (highly expressed in this system) and adding extra promoters and enhancers, we significantly improved the expreesion level of hKGF-1 in Bombyx mori cells. The results demonstrated that the aforementioned strategies significantly enhanced the expression level of hKGF-1 in Bombyx mori cells. SDS-PAGE and Western blotting results revealed that the highest hKGF-1 expression (accounting for 8.7% of total cellular protein) was achieved when the Polh promoter was combined in tandem with the P6.9 promoter and hKGF-1 was fused with a 15-residue polyhedrin fragment for co-expression. The optimal harvest time was determined to be 120 h post transfection. This study achieved the efficient expression of hKGF-1 in Bombyx mori cells, establishing an ideal technological platform for the industrial utilization of recombinant hKGF-1. The developed methodology not only provides valuable technical references for the production of other growth factors and complex proteins, but also demonstrates significant implications for employing silkworms as bioreactors for recombinant human protein expression.

ObjectiveTo study the effects of Huangjing Jiannao granules on learning and memory abilities and cerebral blood flow in the rat model of vascular cognitive impairment （VCI） and to explore the mechanism of Huangjing Jiannao granules in the treatment of VCI. MethodSeventy-two SPF-grade male SD rats were randomly selected， with 12 rats as the sham operation group. The remaining rats were subjected to bilateral carotid artery ligation （2-VO） for the modeling of VCI. According to the randomized block design， the successfully modeled rats were grouped as follows： model， donepezil hydrochloride （0.50 mg·kg^-1）， and low-， medium-， and high-dose （2.36， 4.72， 9.44 g·kg^-1， respectively） Huangjing Jiannao granules. After 6 weeks of treatment， Morris water maze test and new object recognition test were conducted to evaluate the learning and memory abilities of the rats. After continuous gavage for 8 weeks， the cerebral blood flow was recorded by a laser microcirculation blood flow imager， and the survival and injury of hippocampal neurons were observed by Nissl staining. The expression of neuronal nuclear antigen （NeuN） in the hippocampus was detected by immunohistochemistry （IHC）. The levels of interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α） in the serum were determined by enzyme-linked immunosorbent assay. The protein levels of phosphatidylinositol 3-kinase （PI3K）， phosphorylated protein kinase B （p-Akt）， nuclear factor-κB p65 （NF-κB p65）， and nuclear factor-κB inhibitor α （IκBα） in the hippocampus were determined by Western blot. ResultCompared with the sham operation group， the model group showed weakened learning and memory abilities （P<0.01）， reduced blood flow in the whole brain， forebrain， and hindbrain （P<0.01）， damaged neurons and reduced survived neurons in the hippocampal CA1 region （P<0.01）， down-regulated expression of NeuN （P<0.01）， elevated levels of IL-1β and TNF-α in the serum （P<0.01）， up-regulated protein levels of PI3K， p-Akt， and NF-κB p65 in the hippocampal tissue， and down-regulated protein level of IκBα （P<0.01）. Compared with the model group， medium- and high-dose Huangjing Jiannao granules improved the learning and memory abilities （P<0.05，P<0.01）. High-dose Huangjing Jiannao granules increased the blood flow in the whole brain， forebrain， and hindbrain （P<0.05，P<0.01）， and medium-dose Huangjing Jiannao granules increased the blood flow in the whole brain （P<0.05）. All the doses of Huangjing Jiannao granules increased the number of survived neurons （P<0.05，P<0.01） and up-regulated the protein level of NeuN （P<0.05，P<0.01）. Medium and high-dose Huangjing Jiannao granules lowered the level of TNF-α （P<0.05，P<0.01）， down-regulated the protein levels of PI3K， p-Akt， and NF-κB p65 （P<0.05，P<0.01）， and up-regulated the protein level of IκBα （P<0.01）. ConclusionHuangjing Jiannao granules can improve the learning and memory abilities and promote the recovery of cerebral blood flow in the rat model of VCI induced by 2-VO by regulating the expression of proteins involved in the PI3K/Akt signaling pathway， inhibiting inflammation， and reducing hippocampal neuron injury.

Standardized reporting is a crucial factor affecting the use of patient guidelines （PGs）， particularly in the reporting and presentation of recommendations. This paper introduced the current status of PG reporting， including the research on PG content and presentation formats， and provided comprehensive recommendations for PG reporting from aspects such as overall framework， recommendations， presentation format， and readability. First， the presentation of PG recommendations should include clearly defined clinical questions， recommendations and their rationale， and guidance on how patients should implement the interventions； for specific content in the PG， such as level of evidence， level of recommendation， it is recommended to explain in text the reasons for giving different levels of recommendation， i.e.， to present the logic behind giving the level of recommendation to the patient； additional information needed in the recommendation framework should be supplemented by tracing references or authoritative textbooks and literature that support the recommendations. Subsequently， the PG text should be written based on the Reporting Checklist for Public Versions of Guidelines （RIGHT-PVG） reporting framework. Finally， to enhance readability and comprehension， it is recommended to refer to the Patient Education Materials Assessment Tool （PEMAT） for translating PG content. To enhance the readability of PGs， it is suggested to present the PG content in a persona-lized and layered manner.

Since the concept of patient versions of guidelines （PVGs） was introduced into China， several PVGs have been published in China， but we found that there is a big difference between the concept of PVG at home and abroad， and the reason for this difference has not been reasonably explained， which has led to ambiguity and even misapplication of the PVG concept by guideline developers. By analyzing the background and purpose of PVGs， and the understanding of the PVG concept by domestic scholars， we proposed the term patient guidelines （PGs）. This refers to guidelines developed under the principles of evidence-based medicine， centered on health issues that concern patients， and based on the best available evidence， intended for patient use. Except for the general attribute of providing information or education， which is typical of common health education materials， PGs also provide recommendations and assist in decision-making， so PGs include both the patient versions of guidelines （PVG） as defined by the Guidelines International Network （GIN） and "patient-directed guidelines"， i.e. clinical practice guidelines resulting from the adaptation or reformulation of recommendations through clinical practice guidelines.

At present， the process and methodology of patient guidelines （PGs） development varies greatly and lacks systematic and standardised guidance. In addition to the interviews with PG developers， we have sorted out the relevant methodology for the adaptation and development of existing clinical practice guideline recommendations and facilitated expert deliberations to achieve a consensus， so as to finally put forward a proposal for guidance on the process and methodology for the development of PGs. The development of PGs can be divided into the preparation stage， the construction stage， and the completion stage in general， but the specific steps vary according to the different modes of development of PGs. The development process of Model 1 is basically the same as the patient version of the guideline development process provided by the International Guidelines Network， i.e.， team formation， screening of recommendations， guideline drafing， user testing and feedback， approval and dissemination. The developer should also first determine the need for and scope of translating the clinical practice guideline into a patient version during the preparation phase. Model 2 adds user experience and feedback to the conventional clinical practice guideline development process （forming a team， determining the scope of the PG， searching， evaluating and integrating evidence， forming recommendations， writing the guideline， and expert review）. Based on the different models， we sort out the process and methods of PG development and introduce the specific methods of PG development， including how to identify the clinical problem and how to form recommendations based on the existing clinical practice guidelines， with a view to providing reference for guideline developers and related researchers.

Purpose To investigate the expression and po-tential clinical value of heat shock protein 90α(Hsp90α)in co-lon adenocarcinoma.Methods The expression level of Hsp90αin colon adenocarcinoma and its relationship with clinicopatho-logical features,prognosis and immune cell infiltration were ana-lyzed by bioinformatics and immunohistochemistry.The prolifer-ation ability of colon cancer cells before and after Hsp90AA1 knockout was detected by CCK-8 cell proliferation assay and plate cloning assay.Results The bioinformatics tools showed that Hsp90AA1 was abnormally higher in colon cancer tissues than adjacent tissues,and the higher the expression level,the worse the prognosis of patients.The expression of Hsp90AA1 was positively correlated with the infiltration levels of CD4+T cells(Th2),CD8+T cells,myeloid inhibitory cells,Tregs cells,neutrophils,macrophages,M1 macrophages and M2 macropha-ges.Immunohistochemical results showed that the expression of Hsp90α in colon cancer tissues was significantly higher than in its adjacent tissues.The expression of Hsp90α was related to age(P＜0.05),not related to gender,tumor size,location,clini-cal classification,differentiation degree,tumor node metastasis,lympho-vascular invasion,perineural invasion(P＞0.05).The high expression of Hsp90α was an independent risk factor for the prognosis of colon cancer patients.The results of cell experi-ments showed that Hsp90AA1 knockout inhibited the growth and proliferation of colon cancer cells.Conclusion Hsp90α is highly expressed in colon adenocarcinoma,which may be a po-tential molecular marker for poor prognosis of colon adenocarci-noma.

Cancer genomics has led to the discovery of numerous oncogenes and tumor suppressor genes that play critical roles in cancer development and progression.Oncogenes promote cell growth and proliferation,whereas tumor suppressor genes inhibit cell growth and division.The dysregulation of these genes can lead to the development of cancer.Recent studies have focused on non-coding RNAs(ncRNAs),including circular RNA(circRNA),long non-coding RNA(lncRNA),and microRNA(miRNA),as therapeutic targets for cancer.In this article,we discuss the oncogenes and tumor suppressor genes of ncRNAs associated with different types of cancer and their potential as therapeutic targets.Here,we highlight the mechanisms of action of these genes and their clinical applications in cancer treatment.Understanding the molecular mechanisms underlying cancer development and identifying specific therapeutic targets are essential steps towards the development of effective cancer treatments.

This paper summarized the key points and methods in terms of the establishment of the guideline working group and the management of conflict of interests， trying to provide reference for the development of clinical practice guidelines for Chinese patent medicine （CPM）. The establishment of the working group is the first important step for developing CPM guidelines. Considering the characteristics of the clinical practice guidelines for CPM， this study suggests that the three key elements of ‘multidisciplinarity’， ‘clinical relevance’ and ‘geographical representativeness’ should be put focus on when forming the working group. The guideline advisory committee， clinical expert group， evidence systematic evaluation group， secretary group and the external review group should be established. All group members should clarify the conflict of interest， and the process and management method of the conflict of interest should be clearly reported.
