Objective: To explore the application effect of a guided self help intervention based on dialectical behavior therapy (DBT) to address non suicidal self injury (NSSI) behavior among college students, so as to provide a reference for reducing the occurrence of NSSI behavior in this population. Methods: A total of 106 college students with NSSI admitted to the Department of Child and Adolescent Psychology, the Second Affiliated Hospital of Jining Medical University from January 2021 to January 2023 were selected and divided into an observation group and a control group, with 53 cases in each group, using a random number table method. The control group received routine medication treatment and psychological intervention, while the observation group, on the basis of the interventions provided to the control group, implemented dialectical behavior therapy based guided self help. The approach combines group activities, individual counseling, and selfdirected learning, covering four core modules: mindfulness training, distress tolerance, interpersonal effectiveness, and emotion regulation. Meanwhile, data collection, skill check ins, and personalized recommendation pushes were conducted through a WeChat. Both groups were intervented for 12 weeks. Before the intervention and after the intervention, the Adolescent Non suicidal Self injury Behavior Questionnaire, Ottawa Self injury Inventory (OSI), and Barratt Impulsiveness Scale (BIS) were used to evaluate the patients, and the levels of serum neurotransmitters were detected. The χ 2 test, t test, and Cochran s Q test were used for data comparison and analysis. Results: The incidence rates of NSSI in the observation group after 3, 6, and 12 weeks of intervention were 47.17%, 16.98%, and 5.66%, respectively, all lower than those in the control group (67.92%, 35.85%, 20.75%) ( χ 2=4.67, 4.85, 5.27,all P <0.05). After 12 weeks of intervention, in the NSSI Behavior Questionnaire, the total score of the observation group was (17.94±2.69) points, which was lower than that of the control group (23.04±5.11) points; in the Function Questionnaire, the total score of the observation group was (53.24±8.94) points, which was higher than that of the control group (47.74±8.00) points（both P ＜0.05）. In terms of the OSI, the total score of the observation group was (4.49±0.62) points, lower than that of the control group (6.25±0.81) points;in the BIS, the total score of the observation group was (80.76±7.94) points, lower than that of the control group (87.74±9.34) points，and the differences between groups were statistically significant(both P<0.05). After the intervention, the level of 5-hydroxytryptamine in the observation group was (67.93±5.42) ng/mL, higher than (44.72±5.54) ng/mL of the control group; the levels of substance P and cortisol in the observation group were (35.82±4.47) ng/L and (75.64±8.02) μg/L, respectively, both lower than (48.14±5.32) ng/L and (94.53±10.78) μg/L of the control group, and the differences were statistically significant (all P <0.05). Conclusion The guided self help intervention based on DBT is helpful for reducing NSSI behavior among college students.

Objective:To study the clinical features and risk factors of prognosis of neonatal appendicitis.Methods:From January 2014 to December 2022, all infants with neonatal appendicitis and received surgery in our hospital were retrospectively analyzed.Results:A total of 6 cases were enrolled, including 1 boy and 5 girls, with gestational age 36-40 weeks, birth weight 1 990~3 300 g, age of admission 5-11 d and time from illness onset to admission 0.5-4 d. All infants had abdominal distension, combined with vomiting in 4 cases, fever in 3 cases and blood in stool in 1 case. Gastrointestinal perforation was found on preoperative abdominal X-ray in 5 cases. All 6 cases received surgery and confirmed the diagnosis of appendicitis with perforation during the surgery. Appendectomy was performed without mortality. 1 case had Amyand hernia and received high ligation of the hernia sac during operation. 1 case had meningitis and was cured after 3 weeks of antibiotic treatment. 1 case developed adhesive intestinal obstruction 3 months after surgery and underwent intestinal adhesiolysis. One case developed colonic stenosis one month after surgery. The stenotic segment of the colon was resected and primary intestinal anastomosis was performed.Conclusions:Neonatal appendicitis progresses rapidly and is difficult to diagnose. The possibility of appendicitis with perforation should be considered when preoperative abdominal X-ray suggesting pneumoperitoneum. Intraoperatively, it is necessary to pay attention to the relationship between appendiceal perforation and other lesions for comprehensive treatment, and change the surgical approach accordingly.

Three-dimensional printing and intraoperative navigation, which based on three-dimensional visualization technology, also has good application prospects. This paper summarized the application of three-dimensional visualization technology for the diagnosis and treatment of hepatolithiasis in order to help the future research.

Objective Next Generation Sequencing(NGS) platform was used to study the characteristics of hot gene mutations in non-small cell lung cancer (NSCLC). The distribution, type and frequency of mutation sites were systematically analyzed to evaluate the pathogenicity of mutation sites . Methods A total of 94 NSCLC tissue samples were included in this study including paraffin-embedded (FFPE) samples and fresh tissue samples, which were collected from July 2015 to April 2017 at the Qilu Hospital of Shandong University. The patient's age ranged from 35 to 82 years with a median age of 61 years. There were 63 males and 31 females. 22 hot genes in NSCLC were selected as the detection panel, including KRAS, EGFR, BRAF, PIK3CA, AKT1, ERBB2, PTEN, NRAS, STK11, MAP2K1, ALK, DDR2, CTNNB1, MET, TP53, SMAD4, FBXW7, NOTCH1, ERBB4, FGFR1 and FGFR2. Mutation detection was performed using the Ion AmpliSeq Colon and Lung Cancer Panel of the Thermo fisher's Ion Torrent sequencing platform. The sequencing data was analyzed using Ion Torrent suite v4.4.2 software. Results Among the 22 mutant genes commonly found in NSCLC, the mutation frequency of TP53 was the highest, accounting for 46.9％ of all mutations, followed by the EGFR mutation (28.1％); A total of 89 mutations were detected, including 63 hot spot mutations (reported mutations) and 26 new mutations (unreported mutations). The most frequently detected mutation was the frameshift deletion of exon 19 of EGFR, followed by the mutation of exon L858R;Analysis of the mutation in targeted drug sites of EGFR showed that the frameshift deletion of exon 19 of EGFR was the most frequently detected, followed by the mutation of exon L858R on chromosome 21. Bioinformatics software was used to analyze the pathogenicity of 26 new mutation sites. Results showed that in addition to ATK1:c. 47-12G>A and TP53: c. 214 C>G, the remaining 24 new mutation sites had at least one major impact on the gene function in three aspects, including gene conservation, amino acid sequence change and protein structure influence. Conclusion In this study, NGS was used to conduct combined detection of mutation sites of multiple hot genes, which might cover more comprehensively genetic variation and provide a basis for screening the most suitable targeted therapy groups. The pathogenicity prediction of new mutations and the changes in tumor-related signaling pathways involved provide a reference for further study of the pathogenesis of NSCLC.

Objective To clone and express a high mobility group box 1(HMGB1)protein of Schistosoma japonicum(Main-land strain)and analyze its function. Methods The DNA fragment of open reading frame encoding Sj HMGB1 protein was ampli-fied by RT-PCR from the mRNA of S. japonicum worms,then it was subcloned into the expression vector pET28a(+)to form the recombinant expression plasmid SjHMGB1-pET28a. The recombinant expression plasmid was transformed into the component E. coli BL21(DE3),and the tranformant containing recombinant expression plasmid was induced with IPTG to express the recombi-nant protein SjHMGB1. The recombinant SjHMGB1 protein was purified by affinity chromatography with nickel chelating affinity chromatography agarose gel. The Gel retard experiment and animal immunization were performed to analyze the DNA binding ca- pacity and the immunologic property of recombinant SjHMGB1. The expression levels of HMGB1 in different life cycle stages of S. japonicum were analyzed by Western bloting and RT-PCR. Female ICR mice were immunized with the recombinant SjHMGB1 pro-tein and infected with 45±2 cercariae of S. japonicum after three immunizations. Forty-two days post-infection,the worms and eggs of S. japonicum were recovered from the portal vein and liver tissue,respectively. The worm and egg reduction rates were calculat-ed respectively. Results A 530 bp of specific DNA fragment was amplified from mRNA of S. japonicum by RT-PCR,which was the open reading frame(ORF)encoding SjHMGB1protein confirmed by DNA sequencing analysis. The recombinant expression plasmid SjHMGB1-pET28a was constructed by cloning the ORF of SjHMGB1 into a expression vector pET28a(+). The bacterium transformants containing the recombinant plasmid expressed a soluble recombinant protein about 28 kDa after induced by IPTG, and the recombinant SjHMGB1 protein was purified by nickel chelating affinity chromatography. The gel retard experiment showed that the recombinant SjHMGB1 protein could bind to both supercoiled DNA and linear DNA,and the recombinant protein immu-nized mice produced high titers of antiserum IgG. Western bloting indicated that the recombinant SjHMGB1 protein was recognized specifically by the S. japonicum-infected mice serum. Above results showed that the recombinant SjHMGB1 protein possessed both functional activity and immunogenicity as the natural protein. RT-PCR and Western blot results showed that SjHMGB1 was abun-dantly expressed in the adult and egg stages whereas barely detectable in the cercaria stage. The immune protection experiment showed that the recombinant SjHMGB1 induced mice to produce high titers of specific antibody IgG but failed to conduct an effec-tive immune protection against S. japonicum. Conclusion The gene encoding HMGB1 from S. japonicum and the soluble recombi-nant SjHMGB1 protein with natural functional activity are obtained,and the recombinant SjHMGB1 has a high immunogenicity but is not able to induce an effective immune protection against S. japonicum.

Objective To establish a direct reverse transcription real-time fluorescence quantitative polymerase chain reaction ( RT-qPCR-D ) method for detecting serum circulating B cell-specific moloney murine leukemia virus integration site-1 (Bmi-1) mRNA, and analyze the levels of serum circulating Bmi-1 mRNA in colorectal cancer patients by using of this method for exploring its diagnosis value in colorectal cancer.Methods Methodology establishment.RNA was extracted from colorectal cancer HT 29 cell line, and detection standard curves of Bmi-1, ubiquitin C ( UBC), glyceraldehyde-3-phosphate dehydrogenase ( GAPDH) mRNAs were established , then the amplification efficiencies were calculated.Bmi-1 mRNA level was directly detected in serum and preparation buffer mixture , then the specificity of assay was evaluated by melting curve, and detection limit was observed through diluted serum samples.The serum circulating Bmi-1 mRNA levels were detected by ELISA in 158 cases with colorectal cancer , of which there were 26 cases of tumor node metastasis ( TNM)Ⅰstage, 53 cases of TNMⅡ, 47 cases of TNMⅢ, 32 cases of TNMⅣand 53 cases of controls with normal colonoscopy collected from January 2008 to January 2009 in Qilu Hospital of Shandong University.Comparisons of groups were determined by applying Mann-Whitney U test or Kruskal-Wallis test, and receiver operating characteristic ( ROC) curves were established to illustrate the diagnostic performance.Results The log values of Bmi-1, UBC and GAPDH showed good linear correlations with quantification cycle (Cq) values(R2 =0.990, 0.990, 0.991, all P <0.001), and the amplification efficiencies were 0.875, 0.917 and 0.935, respectively.Using the established RT-qPCR-D method, the peak of melting curve of Bmi-1, UBC and GAPDH mRNAs were single, the detection limit was up to 1.25μl.The levels of serum circulating Bmi-1 mRNA detected by RT-qPCR-D were 0.138 ( 0.078-0.228 ) in colorectal cancer stage Ⅰ patients, 0.163(0.067 -0.287) instage Ⅱ patients, 0.217(0.072-0.267) instage Ⅲpatients, 0.273(0.139 -0.419) in stage Ⅳ patients and 0.021(0.008 -0.029) in health controls, a significant difference was found among groups ( H =89.5, P <0.001 ).The levels of serum circulating Bmi-1 mRNA in each stage colorectal cancer were all significantly higher than that in control group(U=58.0, 287, 246, 72.5,all P<0.001).The levels in Ⅳstage patients were significantly higher than those in other stages patients (U=247, 590, 540,P=0.008, 0.020, 0.035), while no significant differences among Ⅰstage,Ⅱstage and Ⅲstage patients(U=633, 514, 1170,all P>0.05).ROC curve analysis showed area under the ROC curve ( AUC) for serum circulating Bmi-1 mRNA was 0.921(95%CI=0.876-0.953), which was significantly superior to the AUC of CEA (0.745, 95%CI=0.680-0.802, Z=4.697, P<0.001 ).When cutoff value was 0.034, the diagnostic sensitivity and specificity was 89.2%(141/158) and 90.6%(48/53), while 41.8%(66/158) and 73.6%(39/53) using CEA.The AUC for combination of circulating Bmi-1 mRNA and CEA was 0.933(95%CI=0.890-0.963 ) , which was no statistical significance when compared with the AUC of circulating Bmi-1 mRNA(Z=4.697, P>0.05).Conclusions The study establishes a higher sensitive, specific for detecting serum circulating Bmi-1 mRNA. Based on this method , serum circulating Bmi-1 mRNA is found to be increased in colorectal cancer , and is superior to traditional tumor marker CEA in diagnosis of colorectal cancer, which may become a potential detection index for early detection of colorectal cancer.
