Objective: To explore the causal link of cumulative ecological risk and future orientation with health risk behaviors among higher vocational college students, so as to provide reference for reducing and preventing health risk behaviors among higher vocational college students. Methods: A longitudinal follow up study was conducted on 612 students using convenience sampling from 2 vocational colleges in Hunan Province. The Cumulative Ecological Risk Scale, Future Orientation Scale, and Health Risk Behavior Scale were used during three follow up visits (T1: September 2022, T2: June 2023, T3: March 2024), and a cross lagged panel model was constructed to examine the longitudinal causal relationship of cumulative ecological risk, future orientation and health risk behaviors. Analysis of longitudinal intermediary effect between variables by Bootstrap. Results: The cumulative ecological risk scores of T1, T2 and T3 among higher vocational college students were (2.94±1.44,2.99±1.63,3.02±1.54), future orientation scores (40.49±4.71,41.51±5.72,41.06±4.35) and health risk behavior scores (3.73±2.01,3.49±2.00,3.23±2.00). The results of repeated measures ANOVA showed that the future orientation score of T2 was higher than that of T1, and the main effect of measurement time was statistically significant ( F=5.09，P＜0.01,η 2=0.02). The health risk behavior score of T1 was higher than that of T2, and the health risk behavior score of T2 was higher than that of T3, and the main effect of measurement time was statistically significant ( F=10.12，P＜0.01,η 2=0.03).The cross lagged model showed good adaptability, with χ 2/df =7.20 ( P <0.01), relative fitting indicators GFI=0.98, CFI=0.99, TLI=0.96, IFI=0.99, NFI =0.99, and absolute fitting indicator RMSEA =0.06. Among them, the T1, T2 cumulative ecological risk showed negatively predictive effects on T2, T3 future orientation ( β =-0.24, -0.47 ), and T1, T2 cumulative ecological risk positively predicted T2, T3 health risk behavior ( β =0.20, 0.24), while T1, T2 future orientation negatively predicted T2, T3 health risk behavior ( β =-0.25, -0.18) ( P ＜0.01). Bootstrap test analysis found that T2 future orientation had a longitudinal mediating effect ( β=0.04, P ＜0.01) on the T1 cumulative ecological risk and T3 health risk behavior. Conclusions The accumulation of ecological risk among higher vocational college students can positively predict health risk behaviors, while future orientation can negatively predict healthrisk behaviors. Moreover, future orientation plays a longitudinal mediating role between accumulated ecological risks and health risk behaviors.

ObjectiveTo explore the possible mechanisms of electroacupuncture at Fengchi （GB 20）， Waiguan （TE 5）， and Yanglingquan （GB 34） in treating chronic migraine from the perspective of nociceptive sensitization. MethodsForty SPF-grade SD rats were randomly divided into blank group， model group， electroacupuncture group， electroacupuncture + agonist group， and inhibitor group， with 8 rats in each group. Except for the blank group， rats were injected intraperitoneally with nitroglycerin to establish a chronic migraine rat model. After successful modeling， the electroacupuncture group received electroacupuncture at bilateral "Fengchi" （GB 20）， "Waiguan" （TE 5）， and "Yanglingquan" （GB 34） for 30 minutes each session. The electroacupuncture + agonist group received the same electroacupuncture treatment and additional injection of protein kinase C （PKC） agonist Phorbol 12-myristate 13-acetate （1.0 ng/μl， 25 μl） via the infraorbital foramen. The inhibitor group received PKC inhibitor Chelerythrine Chloride （1.0 ng/μl， 10 μl） via the infraorbital foramen. The blank group， model group， and inhibitor group underwent restraint for 30 minutes without other interventions. All groups were continuously intervened for 5 days. After the intervention， the nociceptive thresholds （mechanical and thermal pain） of the periorbital area and hind paw were measured. The expression levels of transient receptor potential vanillic acid subtype 1 （TRPV1）， phosphorylated TRPV1 （p-TRPV1）， PKC proteins， Trpv1， Pkc mRNA， and the average fluorescence intensity of transient receptor potential vanillic acid subtype 1 （TRPV1） and PKC in the trigeminal ganglion were detected using Western Blot， real-time fluorescence quantitative PCR， and immunofluorescence methods. ResultsCompared with the blank group， the mechanical and thermal pain thresholds of the periorbital area and hind paw were reduced in the model group， and the protein levels of TRPV1， PKC， p-TRPV1， as well as the mRNA expression of Trpv1 and Pkc， and the average fluorescence intensity of TRPV1 and PKC in the trigeminal ganglion significantly increased （P＜0.05 or P＜0.01）. Compared with the model group， the electroacupuncture group exhibited increased mechanical and thermal pain thresholds in the periorbital and hind paw areas， and decreased protein levels of TRPV1， PKC， p-TRPV1， mRNA expression of Trpv1 and Pkc， and average fluorescence intensity of TRPV1. In the electroacupuncture + agonist group， the average fluorescence intensity of TRPV1 in the trigeminal ganglion decreased. The inhibitor group exhibited increased mechanical pain thresholds in the periorbital area and thermal pain thresholds in the hind paw， along with decreased protein levels of TRPV1， PKC， p-TRPV1， and the average fluorescence intensity of TRPV1 and PKC （P＜0.05 or P＜0.01）. Compared with the electroacupuncture group， the electroacupuncture + agonist group showed an increase in the protein levels of TRPV1， PKC， p-TRPV1， and the mRNA expression of Trpv1 （P＜0.05 or P＜0.01）. ConclusionElectroacupuncture at the "Fengchi" （GB 20）， "Waiguan" （TE 5）， and "Yanglingquan" （GB 34） acupoints can increase the mechanical and thermal pain thresholds in chronic migraine rats and alleviate nociceptive sensitization. The mechanism may be related to the inhibition of PKC/TRPV1 pathway.

Background The mental health status of prison officers is crucial to the efficiency, security, and stability of a prison, and it is essential to pay attention to the factors that influence their mental health. Objective To understand the mental health status of prison officers, and analyze how nature exposure affects their mental health problems and a potential mediating role of mental fatigue. Methods A cross-sectional survey was carried out from May to June 2022 among 1392 prison officers from eight prisons in a province, and a total of 1284 valid questionnaires were recovered. The Nature Exposure Scale, Mental Fatigue Scale, and Depression-Anxiety-Stress Scale were used to assess nature exposure, mental fatigue, and mental health indicators among prison officers, and to explore the effect of nature exposure on mental health problems and a potential mediating role of mental fatigue. Results The recruited prison officers showed high levels of depression, anxiety, and stress. The prevalence rates of depression, anxiety, and stress were 59.11% (759/1284), 60.67% (779/1284),and 43.93% (564/1284), respectively. The results of correlation analysis revealed that nature exposure was negatively related with mental fatigue and mental health indicators (depression, anxiety, and stress) (r_s=−0.242, −0.308, −0.235, −0.254, P<0.01), while mental fatigue was positively correlated with mental health indicators (depression, anxiety, and stress) (r_s=0.546, 0.533, 0.536, P<0.01). The PROCESS macro results showed that the level of nature exposure among prison officers negatively associated with depression, anxiety, and stress (β=−0.180, −0.104, −0.123), and mental fatigue played a mediating role, with indirect effects of −0.200, −0.192, and −0.199, respectively. Conclusion The levels of depression, anxiety, and stress of prison officers are higher than those of other occupations. Nature exposure negatively associates with depression, anxiety, and stress, that is, it may directly alleviate the mental health problems of prison officers; and it may also alleviate mental health problems by relieving mental fatigue.

Objective To explore the feasibility and short-term clinical efficacy of single segment thora-columbar tuberculosis treated with one-stage posterior approach lamina-sparing decompression.Methods A total of 11 patients with single segment thoracolumbar tuberculosis who underwent one-stage posterior ap-proach preservation of vertebral plate lesion removal,bone graft fusion,and internal fixation treatment in this hospital from September 2021 to June 2022 were selected.C-reactive protein(CRP)and erythrocyte sedimen-tation rate(ESR)were monitored to evaluate tuberculosis bacteremia and activity control,visual analogue scale(VAS)score and Oswestry disability index(ODI)were followed up to evaluate the improvement of clin-ical function,and the American Spinal Injury Association(ASIA)injury scale was used to evaluate neurologi-cal function,and the correction of kyphosis was followed up.Results All 11 patients were fully followed up.The average surgical duration is(270.91±45.98)minutes,and the average surgical bleeding is(522.72± 194.11)mL.During the follow-up period,none of the 11 patients experienced tuberculosis recurrence,and all 11 patients achieved bone graft fusion.The fusion time was 6-9 months after surgery with an average of(7.36±1.12)months.Two patients with preoperative nerve damage recovered after surgery.During the fol-low-up period,11 patients did not experience any complications related to surgery.The average CRP,ESR,ODI score,and VAS score of postoperative patients decreased compared to preoperative levels,and further de-creased at 12 months after surgery;The patient's kyphosis caused by thoracolumbar tuberculosis was correc-ted,and no obvious angle loss was found at the last follow-up(P＞0.05).Conclusion One-stage posterior ap-proach lamina-sparing decompression is a safe and effective method for treating single segment thoracolumbar tuberculosis.

Acute myeloid leukemia (AML) is a malignant clonal disease of hematopoietic stem cells, characterized by the proliferation of abnormal primordial cells of myeloid origin in bone marrow, blood and other tissues. At present, the standard induction therapy for AML mainly includes “3+7” standard treatment(anthracycline combined with cytarabine), allogeneic hematopoietic stem cell transplantation (Allo-HSCT) and targeted drug therapy. However, AML cells usually express high levels of P-glycoprotein, which mediates the efflux of chemotherapeutic drugs, which makes AML cells resistant to chemotherapy, resulting in many patients who are not sensitive to chemotherapy or relapse after complete remission. And some patients can not tolerate intensive therapy or lack of donors and can not use Allo-HSCT therapy. Therefore, it is of great clinical significance to find new drugs to improve the efficacy of AML patients. Epigenetic disorders play a key role in the pathogenesis of many diseases, especially cancer. Studies have shown that most AML patients have epigenetic regulatory gene mutations, such as DNMT3A, IDH and TET2, and these mutations are potentially reversible, which has become one of the therapeutic targets of AML. Histone deacetylase inhibitors (HDACi) can regulate the balance between histone acetylation and deacetylation, change the expression of proto-oncogenes or tumor suppressor genes that control cancer progression from epigenetics, and play an important role in many kinds of tumor therapy. At present, HDACi has shown the ability to induce differentiation, cell cycle arrest and apoptosis of AML cells. The mechanism may be mainly related to HDACi inducing chromatin conformation opening of tumor suppressor gene by inhibiting HDAC activity, promoting oncogene damage and preventing oncogene fusion protein from recruiting HDAC. Although the preclinical outcome of HDACi is promising, it is not as effective as the conventional therapy of AML. However, the combination strategy with various anticancer drugs is in clinical trials, showing significant anti-AML activity, improving efficacy through key targeting pathways in a typical synergistic or additive way, increasing AML sensitivity to chemotherapy, reducing tumor growth and metastasis potential, inhibiting cell mitotic activity, inducing cell apoptosis, regulating bone marrow microenvironment, which provides a good choice for the treatment of AML. Especially for those AML patients who are not suitable for intensive therapy and drug resistance to chemotherapy. This review introduces the relationship between HDAC and cancer; the classification of HDAC and its function in AML; the correlation between HDAC and AML; the clinical application of five types of HDACi; preclinical research results and clinical application progress of six kinds of HDACi in AML, such as Vrinota, Belinostat, Panobinostat, Valproic acid, Entinostat, and Chidamide, the mechanism of HDACi combined with other anticancer drugs in AML indicates that the current HDACi is mainly aimed at various subtypes of pan-HDAC inhibitors, with obvious side effects, such as fatigue, thrombocytopenia, nausea, vomiting, diarrhea. In recent years, the next generation of HDACi is mainly focused on the selectivity of analogues or isomers. Finding the best combination of HDACi and other drugs and the best timing of administration to balance the efficacy and adverse reactions is a major challenge in the treatment of AML, and the continued development of selective HDACi with less side effects and more accurate location is the key point for the development of this drug in the future. It is expected to provide reference for clinical treatment of AML.

Objective To investigate the short-term efficacy of celiac plexus block combined with the interstitial permanent implantation of 125I seeds in the treatment of advanced pancreatic cancer(inoperable locally advanced and metastatic pancreatic cancers).Methods A total of 100 patients with advanced pancreatic cancer were selected and treated with celiac plexus block combined with the interstitial permanent implantation of 125I seeds under CT guidance.Pain relief and changes in the tumor marker CA19-9 were assessed on the seventh day,the first and third months after surgery.In the third month after surgery,tumor size was assessed by CT.Results Among the 100 patients with advanced pancreatic cancer,complete response(CR)was found in 12 cases,partial response(PR)in 78 cases,stable disease in five cases,and progression of disease in five cases three months after surgery.The CA19-9 level and the sum of short and long tumor diameters were significantly decreased(both P<0.01).A total of 100 patients had severe pain before treatment(visual analogue scale(VAS)):7-10 points),59 patients reported pain disappearance(VAS:0 points),35 patients had mild pain(VAS:1-3 points),and six patients experienced moderate pain(VAS:4-6 points)in the third month after treatment.The pain relief rate was 100%.Conclusion Celiac plexus block combined with the interstitial permanent implantation of 125I seeds has good short-term efficacy and can effectively improve short-term pain in patients with advanced pancreatic cancer.

Objective Evaluate the performance of the encephalon state index(ESI)in depth of anesthesia monitoring during clinical surgery,compared with the bispectral index(BIS).Methods ESI and BIS data were collected from 60 patients in a single-center clinical trial to compare their efficacy in measuring the depth of anesthesia.Results Consistency analysis revealed mean differences and standard deviations of-0.18±5.42 and-0.11±6.51 between ESI and BIS for awake and anesthetized states,respectively.Correlation analysis showed a correlation coefficient of 0.92 throughout the operative period.Prediction probability analysis indicated that both ESI and BIS had prediction probabilities of 0.97,effectively predicting anesthesia status.Conclusion ESI and BIS show good equivalence in monitoring depth of anesthesia during clinical surgery,which meet the requirements of clinical anesthesia.

Objective:To explore the genetic etiology and clinical outcome of a child with co-morbid progressive IgA nephropathy and COQ8B-associated glomerulopathy. Methods:A child who was admitted to Peking University First Hospital on March 2, 2021 was selected as the study subject. Genomic DNA was extracted from peripheral blood samples from the child and his parents and sister. Whole exome sequencing was carried out, and candidate variant was verified by Sanger sequencing. This study was approved by Medical Ethics Committee of the Peking University First Hospital (Ethics No. 2016[1029]).Results:The child, a 7-year-old boy who had developed proteinuria 8 months before, was diagnosed with IgA nephropathy (M1E1S1T1C1). With steroid, cyclophosphamide, cyclosporine and angiotensin-converting enzyme inhibitor therapy, partial remission of proteinuria was achieved. However, his serum creatinine level had increased from 53.8 mol/L at the onset of disease to 86.7 mol/L after 3.9 years, along with massive proteinuria. Kidney biopsy still indicated IgA nephropathy (M0E0S1T0C0). The child was found to harbor a homozygous c. 737G>A (p.Ser246Asn) missense variant of the COQ8B gene, for which his parents and sister were heterozygous carriers. The variant was predicted to be pathogenic (PS1+ PM2_Supporting+ PM3+ PP3+ PP4) based on the guidelines from the American College of Medical Genetics and Genomics. The child was treated with high-dose coenzyme Q10 in combination with steroid and/or mycophenolate mofetil, though his serum creatinine level still increased to 286 mol/L after 7.3 years, which conformed to a chronic kidney disorder with glomerular filtration rate category of G3b. Conclusion:The homozygous c.737G>A missense variants of the COQ8B gene probably underlay the progressive kidney dysfunction in this child. For children with IgA nephropathy presenting with atypical clinical manifestations, unsatisfactory therapeutic effect, and/or early onset of kidney function decline, coexistence of other diseases should be suspected.
