Three soil conditioners were prepared from granulated food waste and decomposed cattle manure combined with desulfurization gypsum, coal gangue, and maifanite, respectively. Field trials were conducted in the saline field growing Cabernet Sauvignon. The effects of soil conditioners on rhizospheric bacterial communities were studied, with the aim of providing a scientific basis for soil amelioration and restoration. Five treatments were designed, including the control (T1), conventional fertilization (T2), reduced chemical fertilization+organic matter-based soil conditioner with calcium additives (T3), reduced chemical fertilization+organic matter-based soil conditioner with silica additives (T4), and reduced chemical fertilization+organic matter-based soil conditioner with magnesium additives (T5), each with three replications. The results indicated that soil conditioners improved the rhizospheric nutrients, yield, and quality of grape (P<0.05), increased relative abundance of Proteobacteria by 17.32%-23.37%, decreased relative abundance of unidentified_Bacteria and Acidobacteriota by 4.22%-28.42% and 20.88%-35.81%, respectively. The bacterial community composition and diversity were different between treatments. Function analysis showed that the expression levels of the genes involved in chromosome and protein synthesis, mRNA biosynthesis, and glyoxylate and dicarboxylate metabolism were up-regulated in the treatments with soil conditioners. The correlation analysis revealed that multiple environmental factors affected the alpha diversity of rhizospheric bacterial communities, and some bacterial taxa were closely related to the grape yield and quality. It is concluded that soil conditioners can effectively alter rhizosphere nutrient levels and bacterial community structures and functions. T5 treatment outperforms other treatments in improving the physico-chemical and biological characteristics of rhizosphere, and the yield, and quality of grape. It has potential for application, and provides an important basis for development of new-type soil conditioners.

Objective To explore the feasibility of automatic segmentation of clinical target volume(CTV)and organs at risk(OARs)for cervical cancer using AccuLearning(AL)based on geometric and dosimetric indices.Methods Seventy-five CT localization images with manual contouring data of postoperative cervical cancer were enrolled in this study.Sixty cases were randomly selected to trained to generate automatic segmentation model by AL,and the CTV and OARs of the remaining 15 cases were automatically contoured.Radiotherapy plans on the automatic segmentation contours were imported on the CT images of manual contours.The efficiency,Dice similarity coefficient(DSC),Hausdorff distance(HD)and dosimetric parameters were compared between the two methods.Results The time of automatic segmentation was significantly shorter than that of the manual contour(P<0.05).The DSC of all structures were≥0.87.The HD of bowel bag and rectum were about 10 mm,and that of the rest of OARs were less than 5 mm.CTV(D98,V90% ,V95% ,Dmean,HI),bowel bag(V50)and bladder(V50)had significant differences in dosimetric comparison(P<0.05).Conclusion The automatic segmentation model based on AL can improve the efficiency of radiotherapy.Automatic segmentation of OARs has the potential of clinical application,while that of CTV still needs to be further modified.

Objective To explore the correlation between intestinal dose and acute radiation enteritis(ARE)in patients with cervical cancer received concurrent chemoradiotherapy,and optimize the dose limit of intestinal tissue.Methods 158 cervical cancer patients received concurrent chemoradiotherapy from 2014 to 2019 were selected in this study.According to CTCAE 5.0,patients with ARE≥grade 2 were classified as ARE≥grade 2 group,otherwise classified as ARE0.7,P<0.05).Conclusions For patients with cervical cancer received concurrent chemoradiotherapy,the dose of bowelbag V5 and V40 should be considered to rationally optimize the dose of bowelbag in the radiotherapy plan,so as to reduce the incidence of ARE≥grade 2.

Objective:To understand the satisfaction evaluation of contracted residents with " Internet plus" family doctor services and to explore its influencing factors.Methods:From November to December 2021, a stratified random sampling method was used to select 360 contracted residents who had utilized " Internet plus" family doctor services from community health service centers or township health clinics in various counties, cities, or districts of a city in Shandong Province for on-site questionnaire surveys. The purpose was to understand their awareness and satisfaction with the " Internet plus" family doctor services. At the same time, key informant interviews were conducted with contracted residents according to the principle of intensity sampling and information saturation, to collect their opinions and suggestions on the implementation process and model construction of " Internet plus" family doctor services. Descriptive analysis was performed on the data, and a binary logistic regression model was used to analyze the factors affecting the satisfaction of contracted residents with " Internet plus" family doctor services.Results:352 valid questionnaires were obtained. Among the respondents, 108 (30.6%) were very familiar or relatively familiar with the " Internet plus" family doctor service policy, and 251 (71.3%) expressed a high level of satisfaction with the overall " Internet plus" family doctor service. Gender, monthly income status, frequency of participation in health education activities, and satisfaction with the doctor′s daily service attitude, medical technical level, medical service charge level, and the level of communication between the service team and family members were factors affecting the satisfaction of contracted residents with " Internet plus" family doctor services ( P<0.05). Interview results showed that 38 people (95.0%) believed that there were issues with the current implementation of " Internet plus" family doctor services in China, such as the lack of an effective policy support environment, the need to improve the publicity and mobilization effects of contracting institutions, poor service cognition levels among the population, concerns about service quality, misunderstandings about internet-related concepts, network " panic" caused by electronic fraud phenomena, and cultural level differences among the elderly that limited the use of services. Conclusions:The overall satisfaction of contracted residents with the " Internet plus" family doctor services was relatively good. Various factors affected the satisfaction evaluation of contracted residents. It is important to focus on the differences in service psychological perception among contracted residents with different demographic characteristics, strengthen the construction of service teams and service platforms, and improve the public′s cognition and participation in " Internet plus" family doctor services to promote the continuous development of " Internet plus" family doctor services.

Objective To assess the feasibility of utilizing the ExacTracDynamic surface monitoring system(ETD)for setup and body surface monitoring in patients with thoracic tumors undergoing intensity-modulated radio-therapy(IMRT).Methods Patients receiving IMRT for thoracic tumors were included in this study.The enrolled patients were alternatively assigned to either conventional cross curve positioning(control group)or surface monitoring system-assisted positioning(experimental group).ETD X-ray images were utilized for calibration purposes prior to radiotherapy,enabling the determination of setup errors.A region of interest(ROI)was delineated on the body surface above the sternum,and real-time body surface monitoring was performed based on this ROI during radiotherapy.Post-radiotherapy X-ray images were obtained to verify patient position.Data regarding left-right(X),head-foot(Y),abdomen-back(Z),pitch,roll,and yaw directions were recorded and analyzed.Results A total of 60 patients were enrolled,with 754 fractions of radiotherapy in the control group and 718 fractions in the experimental group.The setup errors in the X and Z directions were significantly smaller in the experimental group compared to the control group(P<0.05).Moreover,there was a significant reduction in the number of setup errors≤0.50 cm for X,Y,and Z directions,as well as≤1.00° for Roll angle in the experimental group compared to the control group(P<0.05).Additionally,differences were observed between surface monitoring and X-ray image verification regarding position deviation along Y and Z directions(P<0.05),although these deviations remained within submillimeter levels on average.Conclusion Surface monitoring system-assisted positioning can enhance radiotherapy setup accuracy among thoracic tumor patients,particularly along X and Z directions.Furthermore,when setting ROI above sternum on body surface area,surface monitoring provides better reflection of target area's position deviation.

Objective To investigate the protective effect of AKAP12/PCK6 signaling pathway on podocyte autophagy in diabetic kidney disease(DKD).Methods A total of 40 C57/B6 AKAP12 KO(AKAP12-/-)mice and wild-type(WT)littermates were randomly divided into four groups,with 10 mice in each group:Ctrl+WT group,Ctrl+AKAP12-/-group,DKD+WT group and DKD+AKAP12-/-group.Primary podocytes were obtained from AKAP12-/-mice and WT mice,and exposed to high glucose(HG,30 mmol/L)or mannitol for 24 h to investigate the mitosis and autophagy of podocytes.The primary podocytes were divided into Mannitol+WT,G+WT,Mannitol+AKAP12-/-and HG+AKAP12-/-.In addition,AKAP12-/-podocytes were transfected with sh-PCSK6 to knockdown the expression of PCK6.Mito-Tracker staining was used to analyze the morphology of mitochondria in podocytes.The expressions of mitotic proteins(FIS1 and DRP1),mitochondrial autophagy(PINK1 and Parkin)and autophagy-related proteins(LC3 and p62)were analyzed by Western blot.Results Compared with HG+WT group,the number of single mitochondria and the expression of FIS1,DRP1,PINK1,Parkin,LC3Ⅱ and p62 proteins increased,while the average branch length of mitochondria decreased in HG+AKAP12-/-group(P＜0.05).Compared with HG+sh-NC group,the number of single mitochondria and the expression of FIS1,DRP1,PINK1,Parkin and LC3Ⅱ proteins decreased significantly in HG+sh-PCSK6 group(P＜0.05 or P＜0.01),while the average branch length of mitochondria increased significantly(P＜0.05).Conclusions AKAP12/PCSK6 signaling pathway mediates the regulation of mitochondrion division and mitochondrion autophagy in podocytes under HG environment.

Objective:To explore the mediating role of positive coping style between social support and post-discharge coping difficulty among mothers of premature infants, so as to provide guidance for medical staff to deeply understand and improve the post-discharge coping difficulty of mothers.Methods:A convenience sampling method was employed to select 310 mothers of premature infants from the neonatal intensive care units of five tertiary level A hospitals in Shandong Province from March to June 2023 as the study population. A cross-sectional survey was conducted using the general information questionnaire, the Social Support Rating Scale, the Simple Coping Style Questionnaire, and the Post-Discharge Coping Difficulty Scale-Parent Form.Results:A total of 280 valid questionnaires were returned, among which the age of mothers was (32.70 ± 5.08) years. The score of social support, positive coping style and post-discharge coping difficulty in mothers of preterm infants was (42.59 ± 7.40), (23.06 ± 6.75) and (3.64 ± 1.74) points respectively. Social support was positively associated with positive coping style ( r=0.404, P<0.01), social support and positive coping style were negatively associated with post-discharge coping difficulty ( r=-0.368, -0.369, both P<0.01). Positive coping style partially mediated the relationship between social support and post-discharge coping difficulty, which accounted for 31.11% of the total effect. Conclusions:Social support can affect post-discharge coping difficulty of mothers of premature infants through positive coping style. Medical staff should pay attention to the enhancement of social support and the cultivation of positive coping style of mothers of premature infants, and take targeted measures to reduce the post-discharge coping difficulty.

Objective To investigate the effects of glycosylphosphatidylinositol-anchored HDL-binding protein (GPIHBP1) on glioma growth and macrophage infiltration. Methods Initially, the expression of GPIHBP1 in glioma samples and macrophage infiltration were analyzed using TCGA database, and these bioinformatics results were validated in clinical tissue samples. A stable glioma cell line overexpressing GPIHBP1 was then established to further explore the effects of GPIHBP1 overexpression on glioma cell proliferation, apoptosis, migration, and invasion. Finally, the impact of GPIHBP1 overexpression on tumor growth and macrophage infiltration was verified through xenograft experiments. Results TCGA database analysis revealed that GPIHBP1 expression was higher in low-grade gliomas compared to normal tissues, while it was lower in high-grade gliomas. Additionally, the expression level of GPIHBP1 in low-grade gliomas was higher than in high-grade gliomas, which was confirmed by immunohistochemistry (IHC). Western blot analysis confirmed the successful construction of the GPIHBP1-overexpressing glioma cell line. CCK-8, flow cytometry, scratch and Transwell assays demonstrated that the proliferation, migration and invasion capabilities of the stable cell line were reduced compared to the control group. Xenograft experiments further showed that the tumor growth and macrophage infiltration were decreased in the stable cell line. Conclusion The differential expression of GPIHBP1 in different grades of gliomas may be associated with tumor progression. Overexpression of GPIHBP1 can inhibit glioma growth, possibly by influencing the tumor microenvironment and promoting the polarization of macrophages towards the antitumor M1 phenotype, thereby inhibiting glioma growth.

Objective     To analyse the consistency of perioperative self-reported pain scores of lung cancer patients with clinical records to provide a basis for optimal pain management. Methods    The patients with lung cancer who underwent surgical treatment in the Department of Thoracic Surgery, Sichuan Cancer Hospital from November 2017 to January 2020 were selected. They were divided into two groups based on the source of pain data. The self-report group used a questionnaire in which patients self-reported their pain scores, and the pain scores for the clinical record group were extracted from the electronic medical record system. Kappa test was used to compare the concordance of pain scores between the two groups preoperatively, on postoperative 1-6 days and on the day of discharge. McNemar's paired χ2 test was used to compare the differences in pain intensity levels between the two groups. Binary logistic multi-factor regression was used to analyse the factors influencing the concordance of severe pain (7-10 points) between the two groups. Results     Totally 354 patients were collected, including 191 males and 163 females, with an average age of 55.64± 10.34 years. The median postoperative hospital stay was 6 days. The consistency of pain scores between the two groups was poor (Kappa=–0.035 to 0.262, P<0.05), and the distribution of pain levels at each time point was inconsistent and statistically significant (P<0.001). The percentage of inconsistent severe pain assessment ranged from 0.28% to 35.56%, with the highest percentage of inconsistent severe pain assessment on postoperative day 1 (35.56%). Single-port thoracoscopic surgical access was an influencing factor for inconsistent assessment of severe pain on postoperative day 3 (OR=2.571, P=0.005). Conclusion     Self-reported perioperative pain scores of lung cancer patients are poorly aligned with clinical records. Clinical measures are needed to improve the accuracy of patient pain data reporting by choosing the correct assessment method, increasing education, and developing effective quality control measures.

Objective To investigate the clinical effect of remimazolam combined with remifentanil in patients undergoing laryngoscope vocal cord surgery under general anesthesia.Methods A total of 180 patients undergoing laryngoscope vocal cord surgery under general anesthesia from January to August 2022,77 males and 103 females,aged 18-64 years,BMI 18-30 kg/m2,ASA physical status Ⅰ-Ⅲ were select-ed.The patients were divided into four groups using a random number table method:propofol group(group C),remimazolam 1.0 mg·kg-1·h-1 group(group R1),remimazolam 1.5 mg·kg-1·h-1 group(group R2),and remimazolam 2.0 mg·kg-1·h-1 group(group R3),45 patients in each group.Group C main-tained by intravenous infusion of propofol 5 mg·kg-1·h-1,groups R1,R2,and R3 were maintained by intravenous infusion of remimazolam 1.0,1.5,and 2.0 mg·kg-1·h-1,respectively.All patients were combined with remifentanil 0.2 μg·kg-1·min-1.HR,MAP,and BIS were recorded before anesthesia in-duction(T1),immediately after laryngoscope insertion(T2),immediately at the end of anesthesia mainte-nance(T3),and at tracheal extubation(T4).The onset time of sedation,awakening time,sedation-agita-tion score at extubation and Ramsay score 5 minutes after extubation were recorded.The intraoperative use of ephedrine and nitroglycerin were recorded.The number of injection pain and remedy sedations were recor-ded,the occurrence of adverse reactions such as nausea and vomiting,respiratory depression within 1 hour after extubation,and intraoperative awareness were recorded.Results Compared with group C,MAP at T3,BIS at T2 and T3 were significantly increased,MAP at T4 was significantly decreased,the onset time of sedation was significantly prolonged,the use of ephedrine and the incidence of injection pain were signifi-cantly decreased in group R1(P＜0.05),HR and MAP were significantly decreased at T2 and T4,MAP was significantly increased at T3,the onset time of sedation,awakening time,extubation time were signifi-cantly prolonged,the use of ephedrine and the incidence of injection pain were significantly reduced in group R2(P＜0.05),HR and MAP were significantly decreased at T2 and T4,the onset time of sedation,awakening time,extubation time were significantly prolonged,Ramsay score was significantly increased in group R3(P＜0.05).Compared with group R1,HR and MAP were significantly decreased at T2 and T4,BIS was significantly decreased at T2 and T3,the awakening time and extubation time were significantly pro-longed in group R2(P＜0.05),HR at T2 and T4,MAP at T2-T4,BIS at T2 and T3 were significantly de-creased,the awakening time and extubation time were significantly prolonged,Ramsay score was significant-ly increased in group R3(P＜0.05).Compared with group R2,MAP at T3 was significantly decreased and Ramsay score was significantly increased in group R3(P＜0.05).There were no significantly differences between the rates of nitroglycerin usage,rescue sedation,nausea and vomiting,and respiratory depression in the four groups.Conclusion Remimazolam can be safely used for anesthesia induction and maintenance in laryngoscope vocal cord surgery.The maintenance of remimazolam 1.5 mg·kg-1·h-1 combined with remifentanil can better maintain the hemodynamics stability during the surgery than remimazolam 1.0 and 2.0 mg·kg-1·h-1.
