OBJECTIVETo assess the efficacy of prophylactic treatment with recombinant human thrombopoietin (rhTPO) on chemotherapy-induced thrombocytopenia in tumor patients.

METHODSIn this randomized cross-over self-controlled clinical trial, 24 patients with malignant neoplasms were randomized group A (12 cases) and group B (12 cases). All the patients underwent two identical cycles of chemotherapy. In group A, RhTPO (1.0 µg/kg) was administered subcutaneously on a daily basis 3 days before the second chemotherapy cycle for 7 consecutive days, and in group B, RhTPO was administered daily 6-24 h after the second chemotherapy cycle for 7 days. In both groups, RhTPO was not administered in the first chemotherapy cycle, which served as the control cycle.

RESULTSIn both the groups, platelet count was significantly higher in the second cycle than in the control cycle, and the duration of thrombocytopenia was significantly shortened in the second cycle. Compared with group B, the patients in group A showed a significantly higher platelet count in the second cycle and a significantly shorter duration of thrombocytopenia in the second cycle.

CONCLUSIONProphylactic administration of rhTPO can significantly reduce the severity and duration of thrombocytopenia and promote platelet recovery in patients undergoing chemotherapy for malignant tumors.

Objective:To explore the effects of the LEARNS model in health education of urinary incontinence for patients undergoing laparoscopic radical prostatectomy.Methods:From September 2019 to August 2020, totally 60 patients who underwent laparoscopic radical prostatectomy in the Department of Urinary Surgery, Peking University First Hospital were selected by convenience sampling and divided into a control group and an intervention group according to the time of admission, with 30 cases in each group. Patients in the control group underwent conventional health education, while patients in the intervention group received nursing using the LEARNS model, with specific steps including listen (L), establish (E), adopt (A), reinforce (R), name (N), and strengthen (S). The mastery of knowledge about pelvic floor muscle before discharge was compared between the two groups, and the urinary continence of the two groups at 1 and 3 months after discharge was observed.Results:The knowledge level and correctness of pelvic floor muscle in the intervention group were higher than those in the control group, and the differences were statistically significant ( P<0.01). At 3 months after surgery, the urinary incontinence score of the intervention group was lower than that of the control group; the number of urine pads used was less than that of the control group; the rate of continence was higher than that of the control group, with statistically significant differences ( P<0.01) . Conclusions:The LEARNS mode can effectively improve the mastery of knowledge about pelvic floor muscle in patients undergoing laparoscopic radical prostatectomy, and improve their postoperative urinary continence.

The permanent or temporary stoma left in patients undergoing neostomy affects the patients both physiologically and psychologically. The Registered Nurses Association of Ontario (RNAO) released the clinical practice guidelines of Supporting Adults Who Anticipate or Live with an Ostomy, second edition in 2019. This article interprets the recommendations of this guideline, and focuses on preoperative and postoperative care planning, parastomal hernia prevention, and the quality of life of patients undergoing neostomy, in order to provide clinical practitioners with effective stoma care advice.

Objective:To compare the therapeutic effect of lateral position and half lithotomy position in Asian proximal femur intramedullary nail antirotation system (PFNA-II) for treating the elderly patients with femoral intertrochanteric fractures.Methods:A retrospective case control study was made on 141 patients with femoral intertrochanteric fractures admitted to Jiangjin Central Hospital from January 2016 to September 2017, including 54 males and 87 females, aged 65-99 years (mean, 80.4 years). According to AO classification, there were 42 patients with type A1 fractures, 88 with type A2 and 11 with type A3. Of all, 74 patients were stabilized by PFNA-II internal fixation in lateral position (lateral position group) and 67 patients by PFNA-II internal fixation in half lithotomy position (half lithotomy position group). The postural placement time, total incision length, operative time, intraoperative blood loss, fluoroscopy frequency, tip-apex distance, reduction quality, fracture healing time, postoperative complications and Harris hip function at 12 months after surgery were compared between the two groups.Results:All patients were followed up for 12-18 months (mean, 12.5 months), except that 13 patients were lost after 9 months, an average of 12.5 months. There were no statistically significant differences in postural placement time, operative time, fracture healing time, and Harris hip score between the two groups ( P>0.05). While significant differences were seen between lateral position group and half lithotomy position group regarding the incision length [(6.5±1.3)cm vs. (7.5±1.5)cm], intraoperative blood loss [(84.3±3.1)ml vs. (90.4±3.9)ml], fluoroscopy frequency [(13.1±1.9)times vs. (11.2±1.2)times], tip-apex distance [(20. 6±2.2)mm vs. (24.4±1.8)mm], good rate of reduction quality (80% vs. 85%) and implant related complications (5% vs. 2%) ( P<0.05 or 0.01). Conclusion:For treatment of elderly patients with intertrochanteric fractures, compared to the lateral position, the half lithotomy position in PFNA-II internal fixation can reduce frequency of fluoroscopy, improve quality of fracture reduction and reduce implant-related complications.

Objective To explore the relationship between PANoptosis and hepatic ischemia-reperfusion injury (HIRI), and to screen the key genes of PANoptosis in HIRI. Methods PANoptosis-related differentially expressed genes (PDG) were obtained through the Gene Expression Omnibus database and GeneCards database. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA) were used to explore the biological pathways related to PDG. A protein-protein interaction network was constructed. Key genes were selected, and their diagnostic value was assessed and validated in the HIRI mice. Immune cell infiltration analysis was performed based on the cell-type identification by estimating relative subsets of RNA transcripts. Results A total of 16 PDG were identified. GO analysis showed that PDG were closely related to cellular metabolism. KEGG analysis indicated that PDG were mainly enriched in cellular death pathways such as apoptosis and immune-related signaling pathways such as the tumor necrosis factor signaling pathway. GSEA results showed that key genes were mainly enriched in immune-related signaling pathways such as the mitogen-activated protein kinase (MAPK) signaling pathway. Two key genes, DFFB and TNFSF10, were identified with high accuracy in diagnosing HIRI, with areas under the curve of 0.964 and 1.000, respectively. Immune infiltration analysis showed that the control group had more infiltration of resting natural killer cells, M2 macrophages, etc., while the HIRI group had more infiltration of M0 macrophages, neutrophils, and naive B cells. Real-time quantitative polymerase chain reaction results showed that compared with the Sham group, the relative expression of DFFB messenger RNA in liver tissue of HIRI group mice increased, and the relative expression of TNFSF10 messenger RNA decreased. Cibersort analysis showed that the infiltration abundance of naive B cells was positively correlated with DFFB expression (r=0.70, P=0.035), and the infiltration abundance of M2 macrophages was positively correlated with TNFSF10 expression (r=0.68, P=0.045). Conclusions PANoptosis-related genes DFFB and TNFSF10 may be potential biomarkers and therapeutic targets for HIRI.

Objective:To establish a set of artificial intelligence (AI) verification rules for blood routine analysis.Methods:Blood routine analysis data of 18 474 hospitalized patients from the First Hospital of Jilin University during August 1st to 31st, 2019, were collected as training group for establishment of the AI verification rules,and the corresponding patient age, microscopic examination results, and clinical diagnosis information were collected. 92 laboratory parameters, including blood analysis report parameters, research parameters and alarm information, were used as candidate conditions for AI audit rules; manual verification combining microscopy was considered as standard, marked whether it was passed or blocked. Using decision tree algorithm, AI audit rules are initially established through high-intensity, multi-round and five-fold cross-validation and AI verification rules were optimized by setting important mandatory cases. The performance of AI verification rules was evaluated by comparing the false negative rate, precision rate, recall rate, F1 score, and pass rate with that of the current autoverification rules using Chi-square test. Another cohort of blood routine analysis data of 12 475 hospitalized patients in the First Hospital of Jilin University during November 1sr to 31st, 2023, were collected as validation group for validation of AI verification rules, which underwent simulated verification via the preliminary AI rules, thus performance of AI rules were analyzed by the above indicators. Results:AI verification rules consist of 15 rules and 17 parameters and do distinguish numeric and morphological abnormalities. Compared with auto-verification rules, the true positive rate, the false positive rate, the true negative rate, the false negative rate, the pass rate, the accuracy, the precision rate, the recall rate and F1 score of AI rules in training group were 22.7%, 1.6%, 74.5%, 1.3%, 75.7%, 97.2%, 93.5%, 94.7%, 94.1, respectively.All of them were better than auto-verification rules, and the difference was statistically significant ( P<0.001), and with no important case missed. In validation group, the true positive rate, the false positive rate, the true negative rate, the false negative rate, the pass rate, the accuracy, the precision rate, the recall rate and F1 score were 19.2%, 8.2%, 70.1%, 2.5%, 72.6%, 89.2%, 70.0%, 88.3%, 78.1, respectively, Compared with the auto-verification rules, The false negative rate was lower, the false positive rate and the recall rate were slightly higher, and the difference was statistically significant ( P<0.001). Conclusion:A set of the AI verification rules are established and verified by using decision tree algorithm of machine learning, which can identify, intercept and prompt abnormal results stably, and is moresimple, highly efficient and more accurate in the report of blood analysis test results compared with auto-vefication.

Loofah seeds ribosome inactivating protein luffin-α was fused with a tumor-targeting peptide NGR to create a recombinant protein, and its inhibitory activity on tumor cells and angiogenesis were assessed. luffin-α-NGR fusion gene was obtained by PCR amplification. The fusion gene was ligated with pGEX-6p-1 vector to create a recombinant plasmid pGEX-6p-1/luffin-α-NGR. The plasmid was transformed into E. coli BL21, and the target protein was isolated and purified by GST affinity chromatography. The luffin-α-NGR fusion gene with a full length of 849 bp was successfully obtained, and the optimal soluble expression of the target protein was achieved under the conditions of 16 ℃, 0.5 mmol/L IPTG after 16 h induction. SDS-PAGE and Western blotting confirmed the recombinant protein has an expected molecular weight of 56.6 kDa. Subsequently, the recombinant protein was de-tagged by precision protease digestion. The inhibitory effects of the recombinant protein on liver tumor cells HepG2 and breast cancer cells MDA-MB-231 were significantly stronger than that of luffin-α. The Transwell and CAM experiment proved that the recombinant protein luffin-α-NGR also had a significant inhibitory effect on tumor cells migration and neovascularization. The inhibitory activity on tumor cells and angiogenesis of the recombinant luffin-α-NGR protein lays a foundation for the development of subsequent recombinant tumor-targeting drugs.

ObjectiveTo observe the clinical efficacy and safety of treating mediate-risk pure ground glass pulmonary nodules （pGGNs） based on the state theory. MethodsA prospective clinical randomized controlled trial was used. Totally 141 cases of mediate-risk pGGNs were divided into treatment group （92 cases） and control group （49 cases） according to the random table method. The treatment group was given the basic Sanjie Formula （基础散结方） orally with modification according to the identification of traditional Chinese medicine （TCM） state， 1 dose per day， 3 months as a course of treatment.Three months after the treatment patients were checked by CT. Patients who were clinically judged as cure， moderate to low risk， and turned to surgical resection do not carry out a second course of treatment，and the rest of the patients continued to complete the second courses. Patients in the control group did not receive any treatment and were only followed up periodically. Patients in both groups received a CT review 3 months and 6 months after enrolled. Comprehensive curative effect was evaluated according to the reduction rate of the area of pulmonary nodules shown in chest CT， to further explore the clinical effective difference for patients at different TCM state； the risk of malignancy index （Mayo score） was calculated by Mayo model at enrollment and 3 months and 6 months after enrolled. Adverse events were monitored continuously during the study. ResultsDuring the follow-up， 8 cases in the treatment group and 7 cases in the control group were lost. A total of 126 cases completed the whole process， including 84 cases in the treatment group and 42 cases in the control group. The total effective rates at 3 months and 6 months of the treatment group were 46.15% （30/65） and 45.71% （32/70） in the treatment group， while the total effective rates at 3 months and 6 months in the control group were 12.5% （4/32） and 10.00% （4/40）. Compared with the control group， the comprehensive curative effect of 3 months and 6 months of enrollment in treatment group was significantly better than that in corresponding control group （P＜0.01）. The pulmonary nodule area and Mayo score in the treatment group decreased after 3 and 6 months of enrollment （P＜0.01）. In contrast， there was no statistically significant difference in nodule area between pre- and post-enrollment time points in the control group （P＞0.05）， and probability of Mayo risk increased in the control group after 6 months of enrollment compared to pre-enrollment （P＜0.05）. Among the 84 patients in the treatment group， there were 15 cases of qi deficiency state， 7 cases of yin deficiency state， 5 cases of yang deficiency state， 20 cases of qi depression state， 32 cases of damp-heat state， and 5 cases of harmonious state； the difference in the distribution of the total clinical effective rate of the patients with different TCM states after treatment was statistically significant （P＜0.05）， and the total effective rate of two-by-two comparison of qi depression state was higher （13/20，65.00%） than that of the total effective rate of damp-heat state （8/32，25.00%， P＜0.00833）. There were no significant changes in blood routine， urine routine， liver function and kidney function in both groups， and no adverse events occurred. ConclusionTreating mediate-risk pGGNs based on the state theory can effectively reduce the area of pulmonary nodules and inhibit the growth of malignant risk of pulmonary nodules.
