ObjectiveTo investigate whether anti-PD-1 monoclonal antibody can improve the efficacy and safety of cryoablation combined with lenvatinib in the treatment of unresectable hepatocellular carcinoma （HCC）. MethodsA retrospective analysis was performed for 232 patients with unresectable HCC who were treated at The Fifth Medical Center of Chinese PLA General Hospital from January 2018 to December 2022， among whom 128 received cryoablation combined with lenvatinib （double combination） and 104 received cryoablation combined with lenvatinib and anti-PD-1 monoclonal antibody （triple combination）. Propensity score matching was performed at a ratio of 1∶1， and finally there were 86 patients in each group. The two groups were evaluated in terms of objective response rate （ORR）， disease control rate （DCR）， overall survival （OS）， progression-free survival （PFS）， and adverse events （AEs）. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical data between two groups. Survival curves were plotted， and the Kaplan-Meier method was used to calculate the survival rate of patients in both groups， while the log-rank test was used for comparison between the two groups. The Cox regression model was used to calculate hazard ratio （HR） and 95% confidence interval （CI） and perform the univariate and multivariate analyses of influencing factors for prognosis. ResultsThe median follow-up time was 28 months， and there were 33 deaths （38.0%） in the triple combination group and 40 deaths （46.0%） in the double combination group. Compared with the double combination group， the triple combination group had significantly higher ORR （35.6% vs 14.5%， P=0.008） and DCR （86.1% vs 64.1%， P=0.003）. OS and PFS in the triple combination group were significantly higher than those in the double combination group （P=0.045 and 0.026）. The univariate and multivariate Cox proportional-hazards regression model analyses showed that treatment regimen （HR=0.60， P=0.038） and alpha-fetoprotein level （HR=2.37， P=0.001） were independent risk factors for OS， and treatment regimen （HR=0.65， P=0.025）， diabetes mellitus （HR=1.94， P=0.005）， whether or not to have received local treatment （HR=0.63， P=0.014）， and distant metastasis （HR=0.58， P=0.009） were independent risk factors for PFS. There was no significant difference in the incidence rate of AEs between the two groups （P>0.05）. ConclusionFor patients with unresectable HCC， the triple combination of cryoablation， lenvatinib， and anti-PD-1 monoclonal antibody significantly improves the treatment outcome and survival of patients compared with the double combination of cryoablation and lenvatinib， without increasing AEs， which provides a clinical basis for optimizing the treatment regimen for unresectable HCC.

Objective To investigate the expression of lncRNA SNHG8 in placenta accrete(PA)and its effect on trophoblast invasion and migration.Methods qRT-PCR was used to detect the expression of lncRNA SNHG8 in placenta tissue of 30 cases in PA group and 30 cases in control group,and the correlation between lncRNA SNHG8 expression and prenatal ultrasound score of 30 cases in PA group was analyzed.Transwell and scratch assay were used to detect the effect of lncRNA SNHG8 interference on the invasion and migration of human chorionic trophoblast cells(HTR8/SVneo cells),and western blot was used to detect the expression of MMP-2 and MMP-9.The downstream targets of lncRNA SNHG8 were predicted by StarBase software,and the expression of lncRNA SNHG8 was detected in placental tissues of the two groups.Dual luciferase reporter assay was used to detect the targeting relationship between lncRNA SNHG8 and miR-542-3p.Results Compared with that of the control group,the expression of lncRNA SNHG8 was up-regulated in the placenta tissue of the PA group(P<0.05),and it was positively correlated with prenatal ultrasound score.Interference with lncRNA SNHG8 inhibited the invasion and migration of trophoblast cells(P<0.05);the protein expression of MMP-9 and MMP-2 also decreased signifi-cantly(P<0.05).Biological prediction indicates that miR-542-3p had a binding site with lncRNA SNHG8,and miR-542-3p expression was down-regulated in PA placental tissue(P<0.05).Dual luciferase reporter assay confirmed that lncRNA SNHG8 could target miR-542-3p.Compared with si-SNHG8+inhibitor-NC,co-transfection of si-SNHG8 and miR-542-3p inhibitor enhanced the invasion and migration ability of trophoblast cells(P<0.05).Conclusion lncRNA SNHG8 is highly expressed in PA and is related to the severity of PA.LncRNA SNHG8 promotes the invasion and migration of trophoblast by regulating the level of miR-542-3p.The study suggests that lncRNA SNHG8 plays an important role in the invasion and migration of PA trophoblast cells,which is expected to be a clinical diagnostic biomarker and therapeutic target.

Objective To investigate the treatment of neonatal respiratory distress syndrome by less invasive surfactant administration(LISA)clinical efficacy,complications and influence on blood gas analysis.Methods A total of 100 cases of neonatal respiratory distress syndrome requiring pulmonary surfactant(PS)tracheal injection therapy and admitted to the Jinhua Central Hospital between December 1st 2019 and August 1st 2022 were randomly assigned into treatment group(50 cases)and control group(50 cases).The treatment group of children received PS treatment using LISA technology,while the control group of children received PS treatment using tracheal intubation tracheal instillation PS extubation followed by intubation-surfactant-extubation technology.The clinical treatment effect,blood gas analysis,non-invasive ventilation time,length of hospitalization,and incidence of complications were compared between the two groups.Results The total effective rate of treatment in the treatment group was higher than that in the control group;After 1 hour of PS treatment,the oxygen partial pressure and blood oxygen saturation of the treatment group were higher than those of the control group,while the carbon dioxide partial pressure was lower than that of the control group.The non-invasive assisted ventilation time of the treatment group was shorter than that of the control group.The incidence of bronchopulmonary dysplasia was lower than that of the control group.Their difference were statistically significant(P<0.05).Conclusion The use of LISA technology for PS treatment of NRDS can improve blood gas indicators,shorten non-invasive ventilation time,improve diagnostic and therapeutic effects,reduce the risk of bronchopulmonary dysplasia,and do not increase the incidence of complications such as tracheal mucosal injury and pulmonary hemorrhage in children.

Objective:To analyze the evaluation of the application effect and deficiency of nurses acting as standardized parents in the graduation examination of standardized residency training of pediatrics and further improve and promote the level of standardized parents.Methods:A questionnaire survey was used to collect the scores of nurse standardized parents by students and examiners who took part in the graduation examination of standardized residency training of pediatrics in 2021. And the self-evaluation scores of standardized parents were collected. Counting data were represented by the number of cases and composition ratio. A Chi-square test was used to compare the rates.Results:A total of 125 questionnaires from students and 37 questionnaires from nurse standardized parents were collected, and the overall satisfaction (very satisfied + satisfied) of standardized parents reached 121 (96.80%). In the three dimensions of simulation ability, compliance with question-and-answer rules, and simulated attitude, students believed that the consistency between standardized parents and actual parents in simulated altitude was lower than that in the simulation ability and compliance with question-and-answer rules ( P=0.007, P=0.001). The overall satisfaction of standardized parents (very satisfied + satisfied) reached 87.38% (388/444). There were 26 (70.27%) nurse standardized parents who had the lowest satisfaction with their own performance ability, followed by 28 (75.68%) cases of imitation ability and 30 (81.08%) cases of adaptability. Conclusions:It is feasible to adopt nurse standardized parents in the assessment of standardized residency training of pediatrics, and both students and examiners have higher satisfaction. The next step is to improve the training of nurses standardized parents in the attitude of simulation and, at the same time, enhance the training of imitation ability and adaptability, so as to further expand the construction of standardized parents.

Objective To establish the fingerprint map and method of multi-component content determination of ginger and its processed products,and to evaluate their quality. Methods High performance liquid chromatography (HPLC) was used to establish the fingerprint of ginger and its processed products (dried ginger,baked ginger,ginger charcoal) and the method for the simultaneous determination of content of five components. The data were analyzed by similarity evaluation and chemical pattern recognition. Results The fingerprint of ginger and its processed products was established. The similarity was ranged from 0.931 to 0.996. A total of 15 common peaks were confirmed. Five components (6-ginger phenol,8-ginger phenol,10-ginger phenol,6-ginger enol,zingiberone) were identified when compared with the standard. The content of 6-ginger phenol,8-ginger phenol and 10-ginger phenol in ginger and its processed products(dried ginger,baked ginger,ginger charcoal),which were determined by HPLC,met the standard of Chinese Pharmacopoeia(2020 edition). The content of 6-ginger enol and zingiberone in fresh ginger was very low,but their content increased significantly after processing into dried ginger and baked ginger. Ginger and its processed products can be divided into different category in cluster analysis. Five components with VIP greater than one were selected by orthogonal partial least squares discriminant analysis. Conclusion The HPLC fingerprint and assay method established in this study are specific,simple and feasible,stable and reliable. With the help of chemical pattern recognition method,it can provide reference for the quality evaluation of ginger and its processed products.

Objective To observe the clinical efficacy of Jiangshabanxia nano-paste on nausea and vomiting in end-stage patients and its effect on the quality-of-life (QOL) in cancer patients. Methods 120 end-stage patients with nausea and vomiting symptoms above grade III were randomly divided into observation group and control group. They were treated with Jiangshabanxia nano-paste and placebo paste respectively. The paste patch was changed every 24 hours and used continuously for 7 days. The nausea and vomiting symptom score, the quality-of-life measurement score and KPS score of cancer patients in the two groups were observed to evaluate the curative effect. Results After 7 days of treatment, the symptom scores of nausea and vomiting in the observation group decreased significantly, the KPS score of the observation group increased, and the effective rate was higher than that in the control group. The score of QOL measurement showed that after treatment, the score of main symptom areas and other symptom areas (except external dyspnea, diarrhea and economic difficulties) in the observation group decreased, and the score of overall health area increased. After treatment, the score of main symptom areas and other symptom areas (except external dyspnea, diarrhea and economic difficulties) in the observation group was lower than that in the control group, and the scores of overall health area in the observation group were higher than those in the control group. Conclusion Jiangshabanxia nano-paste has a good clinical efficacy nausea and vomiting in end-stage patients, it also can improve the quality of life end-stage cancer patients.

They were treated with CSII for 14 days and followed up for 5 years. Before and after treatment, fasting blood glucose (FPG), 2-h postprandial blood glucose (2hPG), triglyceride (TG), fasting insulin (FINS), 2-h postprandial insulin (2hINS), glycosylated hemoglobin (HbA1c), superoxide dismutase (SOD), malondialdehyde (MDA) and the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) index, Homeostasis Model Assessment for beta-cell function (HOMA-β) index were compared between before treatment and 5 years after treatment.Results:Five years after treatment, the levels of FPG, 2hPG, TG, HbA1c, MDA and HOMA-IR were lower than those before treatment [FPG: (11.3 ± 1.2) mmol/L vs. (5.9 ± 0.4) mmol/L, t = 15.35, P < 0.01; 2hPG: (18.1 ± 4.2) mmol/L vs. (8.1 ± 1.6) mmol/L, t = 16.83, P < 0.01; TG: (2.9 ± 1.1) mmol/L vs. (1.5 ± 0.6) mmol/L, t = 9.81, P < 0.01; HbA1c: (11.2 ± 2.5)% vs. (5.6 ± 1.0)%, t = 11.48, P < 0.01; MDA: (4.6 ± 1.2) μmol/L vs. (2.7 ± 0.9) μmmol/L, t = 16.37, P < 0.01; HOMA-IR: (2.81 ± 0.35) vs. (1.87 ± 0.32), t = 9.37, P < 0.01]. Five years after treatment, the levels of FINS, 2hINS, SOD and HOMA-β were significantly higher than those before treatment [FINS: (5.6 ± 1.3) mU/L vs. (7.4 ± 1.5) mU/L, t = - 6.15, P < 0.01; 2hINS: (15.8 ± 7.5) mU/L vs. (25.8 ± 9.1) mU/L, t = - 5.65, P < 0.01; SOD: (28.9 ± 7.6) U/L vs. (39.6 ± 7.8) U/L, t = - 7.93, P < 0.01; HOMA-β: (14.36 ± 3.82) vs. (65.67 ± 6.67), t = - 18.72, P < 0.01]. Linear regression analysis showed that HOMA-β was positively correlated with SOD level ( R2 = 0.319, P < 0.01). Five years after treatment, the final outcome was insulin therapy in 3 cases (6.5%), oral medication in 25 cases (54.4%), and lifestyle intervention in 18 cases (39.1%). Conclusion:CS II for the treatment of newly diagnosed diabetes mellitus can effectively inhibit oxidative stress, improve the function of islet β cells, and exhibit long-term effects.

Objective:To explore the prolonged therapeutic regimen for patients with plaque psoriasis, who showed a positive response to 4-week treatment with tazarotene/betamethasone dipropionate cream, but were not completely cured.Methods:A multicenter, randomized, open-labelled, parallel-controlled clinical study was conducted. A total of 232 patients with plaque psoriasis were collected, who showed a positive response to previous 4-week treatment with 0.05%/0.05% tazarotene/betamethasone dipropionate cream, but were not completely cured with the psoriasis area and severity index[PASI] improvement rate being 50%-90%. At week 5, they were randomly and equally divided into 2 groups: test group receiving treatment with 0.05%/0.05% tazarotene/betamethasone dipropionate cream once a day, and control group receiving a sequential regimen of 0.05% tazarotene gel on weekdays once a day followed by 0.05%/0.05% tazarotene/betamethasone dipropionate cream on weekends once a day. After 2-and 4-week prolonged treatment, the efficacy and safety of the 2 therapeutic regimens were evaluated and compared. Measurement data were compared between 2 groups by using covariance analysis or t test, and enumeration data were compared by using chi-square test. Results:From the 5th to the 8th week, 200 out of the 232 patients completed the treatment. Data collected from 110 patients in the test group and 112 in the control group were enrolled into the full analysis set, and those from both 113 patients in the test group and control group were enrolled into safety analysis set. After consecutive 6-and 8-week treatment, the decline rates of the PASI score were 73.05% ± 16.69% and 78.46% ± 15.40% respectively in the test group, which were significantly higher than those in the control group (66.73% ± 21.77%, 67.02% ± 34.19%, respectively, both P < 0.05) . After 6-week treatment, the proportion of subjects who achieved PASI90 was significantly higher in the test group (14 cases, 12.7%) than in the control group (5 cases, 4.5%, χ2=4.842, P=0.028) ; After 8-week treatment, the proportions of subjects who achieved PASI75 and PASI90 (61.8%, 23.6%, respectively) were significantly higher in the test group than in the control group (48.2%, 12.5%, respectively, both P < 0.05) . During the consecutive 8-week treatment, there was no significant difference in the incidence rate of adverse reactions between the test group (15.0%) and control group (23.9%, χ2=2.822, P=0.093) . Conclusion:For patients who showed a positive response to 4-week treatment with 0.05%/0.05% tazarotene/betamethasone dipropionate cream, but were not completely cured, the continuous use of 0.05%/0.05% tazarotene/betamethasone dipropionate cream for 4 weeks is a superior therapeutic regimen compared with the sequential regimen of 0.05% tazarotene gel followed by 0.05%/0.05% tazarotene/betamethasone dipropionate cream.
