Objective To explore the causal relationship between family resilience and mental health in military personnel population.Methods A total of 204 military personnel were recruited from an army unit stationed in Western China with cluster convenience sampling.Family Resilience Scale(FRS)and Symptom Checklist 90(SCL-90)were used to survey them twice,in an interval of 4 months.Amos 26.0 was applied to construct a cross-lag model and analyze the data.Results After controlling mental symptoms from the first survey,family resilience in the first measure significantly predicted mental symptoms in the second measure(β=-0.14,P＜0.05).After controlling for family resilience from the first survey,mental symptoms in the first measure significantly predicted family resilience in the second measure(β=-0.13,P＜0.05).Conclusion The relationship between family resilience and mental health is mutually causal in military personnel,and one predicts the other one.Our findings highlight the key dimensions of the relationship between the two.

Objective:To construct a representative index system for evaluating pediatric orthopedic nursing quality, providing a basis for hospital pediatric orthopedic nursing quality assessment and monitoring.Methods:From April to July 2023, using the "structure-process-outcome" three-dimensional quality structure model as the theoretical framework, a literature review was conducted, and an item pool was formulated. Through two rounds of Delphi method expert consultations, the hierarchical analysis method was finally employed to determine the indicators and their weights at each level.Results:The effective recovery rates of the questionnaire of the two rounds of expert consultations were 100% (20/20), the authority coefficients of experts were 0.87 and 0.88, the coefficients of variation were 0.00 to 0.27 and 0.00 to 0.24. The Kendell harmony coefficients of the second and third indicators in the two rounds of inquiry were 0.140, 0.166 and 0.192, 0.161(all P<0.05). The final pediatric orthopedic nursing quality evaluation index system included 3 primary indicators, 21 secondary indicators and 83 tertiary indicators. Among the primary indicators, the weight of process quality was the highest at 0.493 4, followed by outcome quality at 0.310 8, and the lowest was structural quality at 0.195 8. In the secondary indicators, "assessment criteria of limb blood circulation" had the highest weight at 0.099 8. Conclusions:The constructed pediatric orthopedic nursing quality evaluation index system covers key aspects and is more operationally feasible. It provides better guidance for nursing interventions and quality control.

Fertility preservation technology provides an effective method for protecting the reproductive resources of patients with malignant tumors.At the same time,it is inevitable to face great ethical dilemmas in the process of technological implementation.From an ethical perspective,this paper sorted out the research on fertility preservation in tumor patients abroad,as well as analyzed the ethical issues faced by tumor patients in the communication decision-making and implementation stages of fertility protection.Specifically,these included informing and discussing the reproductive information and preservation choices of tumor patients,fertility decision-making of adolescent tumor patients,psychological support for fertility in tumor patients,ownership and use rights of reproductive materials and their disposal methods,fairness in the allocation of social health resources and other ethical issues.Combining with the actual situation in China,this paper further discussed how to put forward corresponding countermeasures based on following ethical principles such as favorable without harm,informed consent,cautious application,and ethical supervision,with a view to promoting the further development and application of fertility preservation technology in clinical practice.

Objective:To compare the effects of enhanced heat preservation strategies and conventional heat preservation strategies in the operation room on body temperature, coagulation function, and myocardial injury in patients with cervical spinal cord injuries.Methods:A retrospective cohort study was conducted to analyze the clinical data of 160 patients with cervical spinal cord injuries admitted to Second Affiliated Hospital of Xi′an Jiaotong University and Affiliated Honghui Hospital of Xi′an Jiaotong University from February to October 2022, including 82 males and 78 females, aged 38-64 years [(50.6±8.7)years]. Injured segments included C 3 in 19 patients, C 4 in 33, C 5 in 39, C 6 in 38, and C 7 in 31. According to American Spinal Injury Association (ASIA) classification, 10 patients were classified into grade A, 83 grade B, 39 grade C, and 28 grade D. All the patients underwent cervical laminoplasty, decompression and bone graft fusion surgery. According to different heat preservation strategies intraoperatively, the patients were divided into conventional heat preservation group ( n=80) and enhanced heat preservation group ( n=80). The body temperature changes before surgery, at 2 hours during surgery, immediately after surgery, at 2 and 24 hours after surgery were compared between the two groups. The changes of coagulation function before surgery and at 4 hours after surgery were compared between the two groups, including the prothrombin time (PT), thrombin time (TT), and activated partial thromboplastin time (APTT). The incidence of myocardial injury and the number of patients with myocardial injury measured by the indicators of cardiac troponin I (cTnI) and high-sensitivity cardiac troponin T (hs-cTnT) at 48 hours after surgery. Before surgery and at 14 days after surgery, ASIA classification was used to evaluate the neurological functions, including sensory and motor functions between the two groups. The incidence of cardiovascular events at 12 months after surgery were compared between the two groups. Results:A total of 145 patients were followed up for 12-18 months [(15.7±1.6)months]. At 12 months after operation, there were 7 patients in the enhanced heat preservation group were lost to follow-up, compared to 8 patients in the conventional heat preserration group. There was no statistically significant difference in body temperature between the two groups before surgery or at 24 hours after surgery ( P>0.05). At 2 hours during surgery, immediately after surgery and at 2 hours after surgery, the body temperature was (36.90±0.12)℃, (37.00±0.06)℃, and (37.16±0.06)℃ in the enhanced heat preservation group, which were significantly higher than those in the conventional heat preservation group [(36.56±0.03)℃, (36.74±0.08)℃, and (36.84±0.08)℃] ( P<0.01). The serum levels of PT, TT and APTT were not significantly different between the two groups before surgery ( P>0.05), while they were (13.1±1.2)seconds, (19.2±1.1)seconds, and (36.2±3.3)seconds in the enhanced heat preservation group at 4 hours after surgery, which were significantly lower than those in the conventional heat preservation group [(14.3±1.0)seconds, (20.2±1.1)seconds, and (38.7±3.4)seconds] ( P<0.01). The incidence of myocardial injury in the enhanced heat preservation group was 5.0% (4/80) at 48 hours after surgery, which was lower than 12.5% (12/80) in the conventional heat preservation group ( P<0.05). With cTnI as the indicator of myocardial injury, there were 2 patients [2.6%(2/76)] with myocardial injury in the enhanced heat preservation group, which was much lower than 8 patients [11.8%(8/68)] in the conventional heat preservation group ( P<0.05). With hs-cTnT as the indicator of myocardial injury, 8 patients [10.5%(8/76)] in the enhanced heat preservation group experienced myocardial injury, similar with 10 patients [14.7%(10/68)] in the conventional heat preservation group ( P>0.05). There were no statistically significant differences in the ASIA scores of the sensory and motor functions between the two groups before surgery and at 14 days after surgery ( P>0.05). The incidence of cardiovascular events at 12 months after surgery in the conventional heat preservation group was 27.8% (20/72), which was significantly higher than 9.6% (7/73) in the enhanced heat preservation group ( P<0.01). Conclusion:For patients with cervical spinal cord injuries, compared with conventional heat preservation strategies, the enhanced heat preservation strategies in the operating room can improve the patients′ core body temperature and coagulation function, and significantly reduce the incidence of myocardial injury and cardiovascular events.

More and more evidence shows that there is a close relationship between the inflammatory state and coronary heart disease. Inflammatory state triggers the damage of vascular endothelium in the early stage of coronary heart disease and ultimately mediates the formation of atherosclerotic plaque. The mechanism of occurrence and development of heart disease is of great significance. Phlegm is a pathological product formed by the subtle imbalance of the spleen and stomach in the transportation and transformation of water and grain. It is the general summary of a series of abnormally accumulated inflammatory substances， such as low density lipoprotein， inflammatory cells， and inflammatory factors. The nature of Phlegm determines the invasiveness and turbidity of Phlegm. Phlegm invades the meridians， causing damage to the meridians and gradually accumulating， which eventually causes the local meridian damage to aggravate. This process is similar to the persistent damage of the vascular endothelium caused by inflammation. Phlegm blocks the meridians， affects the operation of Qi and blood， causes Qi stagnation and blood stasis， and finally forms the outcome of heart and blood stasis. This process is similar to the mechanism of atherosclerotic plaques formed by continuous inflammatory damage. Heart blood stasis， depression and heat， heat toxin endogenous， forming the syndrome of heat toxin stasis， which is similar to the process of atherosclerotic plaque rupture and thrombosis causing acute cardiovascular events.The formation of Phlegm is rooted in the deficiency of spleen. Based on the ''phlegm，stasis，toxin'' theory， spleen deficiency is the intrinsic pathogenesis of the inflammatory state of coronary heart disease， and the invasion of phlegm， blood stasis of heart， heat and blood stasis are the evolution of inflammatory damage of coronary heart disease. Traditional Chinese medicine differentiation and treatment is based on strengthening the spleen and nourishing Qi to treat the root and removing phlegm and blood stasis， and clearing heat and detoxifying to treat symptoms. The related Chinese medicine compounds， Chinese patent medicines， and single Chinese medicines can reduce the inflammatory indicators of coronary heart disease， thereby improving the prognosis of coronary heart disease.

Traditional pig breeding has a long cycle and high cost, and there is an urgent need to use new technologies to revitalize the pig breeding industry. The recently emerged CRISPR/Cas9 genome editing technique shows great potential in pig genetic improvement, and has since become a research hotspot. Base editor is a new base editing technology developed based on the CRISPR/Cas9 system, which can achieve targeted mutation of a single base. CRISPR/Cas9 technology is easy to operate and simple to design, but it can lead to DNA double strand breaks, unstable gene structures, and random insertion and deletion of genes, which greatly restricts the application of this technique. Different from CRISPR/Cas9 technique, the single base editing technique does not produce double strand breaks. Therefore, it has higher accuracy and safety for genome editing, and is expected to advance the pig genetic breeding applications. This review summarized the working principle and shortcomings of CRISPR/Cas9 technique, the development and advantages of single base editing, the principles and application characteristics of different base editors and their applications in pig genetic improvement, with the aim to facilitate genome editing-assisted genetic breeding of pig.

Autophagy is a lysosome-dependent intracellular degradation process，and it is a key mechanism of diabetic cardiomyopathy （DCM）. Autophagy has dual regulatory effects on DCM. Under physiological conditions，normal autophagy can promote the decomposition of damaged cardiomyocytes and metabolites，so as to reduce the damage of harmful substances to the body and provide energy for cardiomyocytes. Under pathological conditions，the inhibited autophagy of cardiomyocytes will cause the accumulation of damaged cells and metabolites，which will cause damage to cardiomyocytes and eventually aggravate cardiac dysfunction in the patients with DCM. However，the over autophagy of cardiomyocytes will lead to autophagic death of a large number of cardiomyocytes and result in pathological myocardial remodeling and cardiac dysfunction，thus promoting the progression of DCM. Therefore，the restoration of a normal autophagy level is the key means to protect cardiomyocytes and improve the prognosis of DCM. Chinese medicine can regulate autophagy to treat DCM. Specifically，it can promote autophagy （making up for deficiency） or inhibit autophagy （removing excess） to restore the balance of autophagy，thereby alleviating DCM.

Non-coding RNAs(ncRNAs) are special RNAs that they don't have protein coding function, but they can affect chromosome structure, gene transcription and participate in the processes of epigenetic modifications. ncRNAs include long non-coding RNAs, microRNA, etc. In recent years, it has been found that these ncRNAs can maintain bone remodeling by adjusting bone resorption and formation in osteoporosis(OP). In the future, it may be a key target of the drug action screening which is clarifying the regulatory mechanism of ncRNAs in the occurrence and development of OP. OP belongs to bone rheumatism category in traditional Chinese medicine, according to the theory of “the kidney generating marrow and dominating bone” in traditional Chinese medicine, kidney tonifying and bone strengthening formulas are used to treat the OP in clinic, and the curative effect is remarkable. It has been found that kidney tonifying and bone strengthening prescriptions can enhance the proliferation of osteoblasts or inhibit the differentiation of osteoclasts by up-regulating or down-regulating the expression of ncRNA, and finally maintain OP bone homeostasis, thus exerting therapeutic effect. However, the specific molecular mechanism is still in its exploratory stage. Therefore, this paper summarized the molecular mechanism of kidney tonifying and bone strengthening prescriptions regulating ncRNAs in the treatment of OP in recent years, in order to provide the new ideas for the screening of the key therapeutic targets of OP drugs and the prevention and treatment of OP with traditional Chinese medicine.

Atherosclerotic cardiovascular disease is a common disease with high incidence rate and mortality worldwide. Atherosclerosis is an important pathological basis for the formation of ischemic cardiovascular diseases such as cardiovascular disease， which is related to inflammation， oxidative stress， apoptosis， vascular endothelial damage， foam cell formation， platelet activation， and so on， involving mitogen-activated protein kinase （MAPK）， phosphoinositide 3-kinase/protein kinase B （PI3K/Akt）， cyclic adenosine monophosphate/protein kinase A （cAMP/PKA）， Ras homolog gene family member A （RhoA）/Rho-associated coiled-coil containing protein kinase （ROCK）， nuclear factor-kappa B （NF-κB）， and other signaling pathways. In the past few decades， high-intensity statins were mainly used to treat atherosclerosis by reducing blood lipid levels， which usually caused obvious side effects. Therefore， the development of safer and more effective drugs and treatment modes is the focus of research at this stage. In recent years， Chinese medicine has been playing an increasingly important role in the prevention and treatment of cardiovascular diseases in China. There are many studies on the mechanism of Chinese medicine in the prevention and treatment of atherosclerosis， and it is found that a variety of single Chinese medicine regulate the formation process of atherosclerosis by regulating targeted signal molecules. This paper reviewed the research results of related signaling pathways involved in the pathological formation of atherosclerosis and the mechanism of Chinese medicine in the prevention and treatment of cardiovascular diseases， thereby providing references for the clinical treatment of cardiovascular diseases.
