Objective To investigate the expression and clinical significance of heat shock protein family A member 5(HSPA5)and apolipoprotein B mRNA editing enzyme catalytic polypeptide-like protein 3B(APO-BEC3B)in high-risk human papillomavirus(HR-HPV)positive cervical cancer patients.Methods A total of 86 patients with HR-HPV positive cervical cancer tissues diagnosed and treated in Zhuhai Integrated Tradi-tional Chinese and Western Medicine Hospital from March 2019 to March 2021 were retrospectively collected as the case group,50 cases of HR-HPV negative cervical cancer patients tissues diagnosed and treated during the same period were selected as the case control group,and 50 cases of normal cervical tissues from patients undergoing total hysterectomy were selected as the benign control group during the same period.The protein expressions of HSPA5 and APOBEC3B were analyzed by immunohistochemistry.The expressions of HSPA5 mRNA and APOBEC3B mRNA were detected by real-time fluorescence quantitative PCR.Kaplan-Meier sur-vival curve was used for survival analysis,and Cox proportional hazards regression model was used to analyze the prognostic factors of HR-HPV positive cervical cancer patients.Results The expressions of HSPA5 mR-NA and APOBEC3B mRNA in the case group were higher than that in the case control group and benign con-trol group,and the difference was statistically significant(P＜0.05).The positive expressions of HSPA5 pro-tein and APOBEC3B protein in the case group were higher than those in the case control group and the benign control group,and the difference was statistically significant(P＜0.05).Compared with FIGO stage Ⅰ A-Ⅰ B and without lymph node metastasis,the positive rates of HSPA5 and APOBEC3B proteins in HR-HPV positive cancer tissues with FIGO stage Ⅱ A and lymph node metastasis were higher,and the difference was statistically significant(P＜0.05).The 3-year survival rate of HSPA5 protein positive group was 68.52％(37/54),which was lower than that of HSPA5 protein negative group(87.50％,28/32),and the difference was statistically significant(Log Rank x2=4.103,P=0.043).The 3-year survival rate of APOBEC3B protein positive group was 67.31％(35/52),which was lower than that of APOBEC3B protein negative group(88.24％,30/34),and the difference was statistically significant(Log Rank x2=5.241,P=0.022).FIGO stage(HR=1.570,95％CI:1.038-2.374),lymph node metastasis(HR=1.754,95％CI:1.109-2.775)and HSPA5 protein(HR=1.616,95％CI:1.154-2.265)and APOBEC3B protein(HR=1.449,95％CI:1.095-1.918)in cancer tissues were independent factors affecting the prognosis of HR-HPV positive cervical cancer(P＜0.05).Conclusion HSPA5 and APOBEC3B mRNA and protein levels are significantly increased in HR-HPV positive cervical cancer.The protein expression of HSPA5 and APOBEC3B is related to the pro-gression and prognosis of patients with HR-HPV positive cervical cancer,which is a new prognostic marker for evaluating the prognosis of HR-HPV positive cervical cancer.

Objective To screen the influencing factors of hepatitis C cirrhosis patients progressing to hepatocellular carcinoma(HCC)using commonly used laboratory testing indicators,establish a prediction model using these indicators and validate them.Methods A total of 231 patients with hepatitis C cirrhosis and 179 patients with hepatitis C HCC hospitalized at the First Affiliated Hospital of Xi'an Jiaotong University between June 2020 and May 2023 were enrolled as the training set,and 105 patients with hepatitis C cirrhosis and 86 patients with hepatitis C HCC hospitalized between June 2023 and February 2024 were enrolled as the validation set.The routine laboratory test indexes of the study subjects in the two groups within the training set were compared,and logistic regression analysis was applied to screen the independent predictors of hepatocellular carcinoma occurrence.Receiver operating characteristic(ROC)curve was used to construct the curve model and validate the model.Results The age,male ratio,ALT,AST,AFP,WBC,NEU,MO,PLT,MPV,PDW,Fbg,NLR and PLR levels of the HCC group were higher than those of the cirrhosis group in the training set(H=-9.07～-2.19),while the levels of INR and LMR were lower than those of the cirrhosis group(H=-4.49,-2.65),and the differences were significant(all P＜0.05).The differences in TP,eGFR,LY and AST/ALT values between the two groups of patients were not significant(H=-1.46～-0.15,all P＞0.05).Multifactorial Logistic regression analysis showed that age(OR=1.048,95％CI:1.023～1.074),Male(OR=1.467,95％CI:1.413～1.765),AST(OR=1.010,95％CI:1.002～1.019),NEU(OR=1.186,95％CI:1.018～1.382)and Fbg(OR=2.245,95％CI:1.639～3.076)were independent risk factors for hepatocellular carcinoma patients(all P＜0.05),and these five independent risk factors were used to construct the HCC column-line graph prediction model,with the AUC for the training set and the validation set AUC(95％Cl)were 0.813(0.771～0.854)and 0.712(0.639～0.784),respectively,and the Hosmer-Lemeshow test showed a good fit of the model with P=0.650 for the training set and P=0.310 for the validation set.Conclusion The prediction model of HCC based on age,gender,AST,NEU and Fbg can have good predictive efficacy and clinical application value.

Natural compounds demonstrate unique therapeutic advantages for cancer treatment, primarily through direct tumor suppression or interference with the tumor microenvironment (TME). Glycyrrhizic acid (GL), a bioactive ingredient derived from the medicinal herb Glycyrrhiza uralensis Fisch., and its sapogenin glycyrrhetinic acid (GA), have been recognized for their ability to inhibit angiogenesis and remodel the TME. Consequently, the combination of GL with other therapeutic agents offers superior therapeutic benefits. Given GL's amphiphilic structure, self-assembly capability, and liver cancer targeting capacity, various GL-based nanoscale drug delivery systems have been developed. These GL-based nanosystems exhibit angiogenesis suppression and TME regulation properties, synergistically enhancing anti-cancer effects. This review summarizes recent advances in GL-based nanosystems, including polymer-drug micelles, drug-drug assembly nanoparticles (NPs), liposomes, and nanogels, for cancer treatment and tumor postoperative care, providing new insights into the anti-cancer potential of natural compounds. Additionally, the review discusses existing challenges and future perspectives for translating GL-based nanosystems from bench to bedside.

Objective:To analyze the burden and changing trends of periodontal disease in adults of the mainland of China from 1990 to 2019, and to predict the incidence trends of periodontal disease in the next 25 years, with a goal to provide a basis for reducing the burden of periodontal disease and formulating relevant prevention and treatment measures.Methods:Data on the incidence, prevalence, and disability adjusted life years (DALY) rate of periodontal disease among adults in the mainland of China from 1990 to 2019 were extracted from the global burden of disease study 2019 (GBD 2019) database. The estimated annual percent change (EAPC) was used to estimate the temporal trend of periodontal disease, and the age-period-cohort model (APC) was used to predict the age-standardized incidence of periodontal disease in Chinese adults from 2020 to 2044.Results:From 1990 to 2019, the incidence, prevalence, and DALY rate of adult periodontal disease in the mainland of China showed an increasing trend, with EAPCs of 0.3 (95% CI: 0.1-0.6), 0.5 (95% CI: 0.1-0.8), and 0.5 (95% CI: 0.1-0.8), respectively. The incidence and prevalence of periodontitis among the population aged 35-39 years old and 40-44 years old increased the most significantly, with EAPCs of 0.8 and 0.7, respectively, whereas the change in periodontal disease prevalence tended to be stable and the increase trend in prevalence was lower in the elderly group (EAPC=0.4). The incidence (EAPC=2.1), prevalence (EAPC=2.6) and DALY rate (EAPC=2.6) of periodontal disease in females increased more than those in males (EAPC=1.9, 2.4, and 2.4, respectively), of which the prevalence had exceeded that of males in 2019. The APC model predicted that the prevalence of periodontal disease in the period of 2020-2044 in China would still be on an upward trend, and the increase rate would be higher in females than in males. Conclusions:The burden of periodontal disease among adults in China had been increasing over the past 30 years, especially among young and middle-aged adults as well as females, and the incidence of periodontal disease will continue to increase over the next 25 years.

Objective:To explore the effect of continuing care based on the WeChat public platform questionnaire star on the fluid replacement operation of peritoneal dialysis patients.Methods:Convenience sampling method was used to select 210 patients undergoing peritoneal dialysis in the Panyu Central Hospital, Guangzhou from January to June 2019. They were divided into a experimental group and a control group by random number table method, each with 105 cases. The patients of the control group were given routine continuous care for peritoneal dialysis, such as outpatient follow-up, telephone follow-up, home visit, etc., and oral education. On this basis, in the experimental group, the patients first joined the WeChat public platform, implementing network-based health education and questionnaire stars for real-time testing, and multi-dimensional communication with patients. The knowledge of the peritoneal dialysis fluid replacement operation, the fluid replacement operation evaluation score, the catheter outlet replacement drug evaluation score, the fluid replacement operation self-management score and compliance were compared before and after intervention in the two groups. And the incidence of complications related to the peritoneal dialysis fluid exchange operation of the two groups were compared before and after intervention.Results:The experimental group′s knowledge of peritoneal dialysis fluid exchange operation, examination score of fluid exchange operation, and abnormal situation management score of fluid exchange operation management were 55.88±8.97, 92(89, 96), 12(11, 12) after three-month intervention, and higher than the control group [51.88±10.24, 91 (86, 94), 12 (9, 12)], with statistically significant difference ( t value was 3.00, Z value was -2.483, -2.308, P<0.05). After six-month intervention, the relevant knowledge of peritoneal dialysis fluid replacement operation, fluid replacement operation evaluation score, catheter outlet replacement drug evaluation score and fluid replacement operation management score (routine fluid replacement operation, abnormal situation handling) of the experimental group were 57.52±9.41, 93 (90,96), 90 (87,94), 18 (17,18), 12 (11,12), which were higher than the control group [53.61±10.29, 90 (86,94), 90 (87,92), 17 (15,17), 12 (9,12)], with statistically significant difference ( t value was 2.87, Z value was from -7.181 to -2.664, P<0.01). The difference between the groups was statistically significant ( χ2 value was 4.21-7.517, all P<0.05); and the difference between the intervention time points was statistically significant ( χ2 value was 11.805-164.95, all P<0.05). After six-month intervention, the complications of catheter infection, peritonitis, and poor drainage were 9 (8.91%), 5 (4.95%), and 5 (4.95%) in the experimental group, which were significantly lower than those in the control group [21 (20.39%), 14 (13.59%), 15 (14.56%)], with statistically significant differences ( χ2 value was 5.36, 4.51, 5.33, both P<0.05). Conclusions:The continuous care of the WeChat public platform questionnaire star has a significant promotion effect on the improvement of the knowledge, operation ability, compliance and self-management behavior of the peritoneal dialysis patients, and can effectively reduce the complications caused by the peritoneal dialysis operation.

Objective:To study the clinical value of the ISBAR communication model based on nursing priorities in nursing ward rounds.Methods:Using a quasi-experiment method, 104 patients who received secondary and tertiary care from April to June 2020 were set as the control group, and 122 patients who received secondary and tertiary care from July to September 2020 were set up as the experimental group, with non-randomized method. The experimental group used the ISBAR communication model based on nursing priorities for nursing ward rounds, and the control group used the traditional method for nursing ward rounds. The abilities of bedside nurses collecting the patients′condition, the bedside nurses′ condition observation and the nurses′ critical thinking were compared between the two groups, and the patients' nursing quality and satisfaction were also compared.Results:The scores of the bedside nurses′ knowledge of the patients′ condition were 81.14±3.09 in the test group and 75.90±2.84 in the control group, with statistically significant difference ( t value was -12.88, P<0.01). The scores of the bedside nurses′ ability in observing patients′ condition were 140.50 (137.00, 144.50) in the experimental group and 135.50 (128.75, 139.00) in the control group, with statistically significant difference ( Z value was -3.399, P<0.01). The scores of the Critical Thinking Disposition Inventory Chinese-version (CTDI-CV) were 309.82±36.33 in the experimental group and 286.86±33.54 in the control group, with statistically significant difference ( t value was -2.177, P<0.05). The scores of patient care quality evaluation were 62.50 (60.00, 64.00) in the experimental group and 59.00 (55.00, 61.50) in the control group, with statistically significant difference ( Z value was -6.47, P<0.01). The patient discharge satisfaction score of the experimental group was 53.00 (48.75, 55.00), and that of the control group was 51.00 (44.00, 54.00), with statistically significant difference ( Z value was -3.56, P<0.01). Conclusions:The application of ISBAR communication model based on nursing priorities in nursing ward rounds had a significant promotion effect on the improvement of nurses' abilities of collecting the patients′ condition, observing patients′ condition, and critical thinking, and can effectively improve nursing care quality and patients′ satisfaction.

Objective:To analyze the longitudinal characteristics of CD4 +T lymphocytes (CD4) among the adult HIV/AIDS on antiretroviral therapy (ART) and the related factors. Methods:A retrospective cohort of adult HIV/AIDS starting ART in Dehong Dai and Jingpo Autonomous Prefecture (Dehong) in 2007-2016 was followed up to December 31, 2018. Group-based trajectory models were utilized to identify CD4 subgroups based on immune recovery (whether and when CD4 reached the average level of >500 cells/μl). The demographics and information at ART baseline were described, and the related factors were analyzed with polytomous logistic regression. The SAS 9.4 software was used for statistical analysis.Results:A total of 7 605 adults with HIV/AIDS were included, of which the median ( P 25, P 75) age at ART were 36 (30,43) years old, 61.0% were male, 42.5% were Han nationality, and 60.8% with the education of primary school or below. The follow-up duration M ( P 25, P 75) was 6.1 (4.1,8.1) years. HIV/AIDS in Dehong showed four CD4 trajectory subgroups from low to high: below the average level, primary recovery to a normal level, full recovery to a moderate level, and normal steady level, accounting for 34.4%, 39.8%, 20.6%, and 5.2%, respectively. When compared with corresponding control groups, age <35 years at ART, female, education of middle school or above, sexual transmission, no opportunistic infection, CD4 ≥200 cells/μl, baseline regimen with tenofovir (TDF) and time from HIV diagnosis to ART <1 year were the related factors facilitating the higher CD4 subgroups. Conclusions:The various CD4 immune recoveries of HIV/AIDS were changing patterns after ART. Starting ART with a high CD4 level was beneficial to CD4 recovery to normal level during the follow-up period. Early initiation of ART and exceptional attention to CD4 immune recovery should be encouraged after the ART.

Objective To explore the timeliness value of cardiopulmonary resuscitation quality index (CQI) in patients' prognostic evaluation during cardiopulmonary resuscitation (CPR).Methods A prospective descriptive study was conducted.According to whether they got return of spontaneously circulation (ROSC) or not,45 patients receiving CPR were divided into the ROSC group and non-ROSC group.The changes of CQI and partial pressure of end-tidal carbon dioxide (PETCO2) during CPR were collected,and were analyzed to valuate the prognosis of patients.Results The initial,end,and average PETCO2 were statistically different between the ROSC group and the non-ROSC group [7.0(3.6,14.6) vs 7.0(3.6,14.6) mmHg;29.5(19.8,35.9) vs 4.0(2.3,10.2)mmHg;and 22.2(11.8,36.3) vs 4.0(2.5,9.0) mmHg,respectively;P＜0.05],and the end CQI was statistically different between the two groups (59.6±8.9 vs 34.8±5.2,P＜0.05).The CQI differences between the two groups initiated at 11 min after CPR,and stopped at 29 min after CPR.The optimal cut-offpoint of terminal CQI and PETCO2 for prognostic was 33.2 and 16.1 mmHg respectively,and there was a statistically difference in the area under the curve between them (P＜0.05).Conclusions During CPR,both CQI and PETCO2 can be used to evaluate the prognosis,and CQI is more capable of predicting in the late stage of CPR.
