ObjectiveTo evaluate the clinical efficacy of Xu's Shenqiyizhu （SQYZ） decoction combined with chemotherapy in the treatment of cancer-related fatigue （CRF） of stagnated-toxin spleen deficiency type after gastric cancer surgery and explore its possible mechanism. MethodsFifty postoperative gastric cancer patients with CRF of stagnated-toxin spleen deficiency type were selected and randomly divided into an experimental group and a control group by using a random number table，with 25 cases in each group. The control group was treated with FLOT chemotherapy （50 mg·m^-2 docetaxel （iv drip on day 1） + 85 mg·m^-2 oxaliplatin （iv drip on day 1） + 200 mg·m^-2 calcium folinate （iv drip on day 1） + 2 600 mg·m^-2 fluorouracil （iv drip for 24 h on day 1），once every three weeks） and basic and symptomatic supportive treatment. The experimental group was treated with Xu's SQYZ decoction （decocted twice，200 mL taken orally twice a day） in addition to the treatment of the control group. One course of treatment lasted for three weeks，with a total of four courses conducted. Observation was performed on the piper fatigue scale （PFS） scores，karnofsky performance status （KPS） scores，European Organization for Research and Treatment of cancer quality of life questionnaire （EORTC QLQ-C30） scores，traditional Chinese medicine syndrome scores，and serum levels of tumor necrosis factor-α （TNF-α），interferon-γ （IFN-γ），and interleukin-6 （IL-6）detected via enzyme linked immunosorbent assay （ELISA） before and after treatment in the two groups. The safety test results before and after treatment for the two groups of patients，as well as the occurrence of adverse events during treatment， were recorded. Transcriptome sequencing data of peripheral blood samples from gastric adenocarcinoma patients and normal individuals were downloaded from the gene expression omnibus （GEO） database，and differentially expressed genes between the tumor and normal groups were identified. Differential gene enrichment analysis was made based on the Kyoto Encyclopedia of Genes and Genomes （KEGG） and Gene Ontology （GO）. The CRF relevance scores of genes were retrieved from the GeneCards database. Results① Compared with that before treatment，the total PFS score in the experimental group was significantly reduced （P<0.05）. Compared with the control group after treatment，the experimental group showed significantly reduced total PFS score （P<0.05）. ② Compared with that before treatment，the KPS score in the experimental group decreased significantly （P<0.05）. Compared with the control group after treatment，the experimental group exhibited a significantly decreased KPS score （P<0.05）. The experimental group demonstrated significantly increased functional scores （physical function，role function，emotional function，social function，and overall health） （P<0.05） and significantly reduced symptom scores （fatigue，shortness of breath，loss of appetite，constipation，and diarrhea） of the EORTC QLQ-C30 scale after treatment compared with before treatment. Compared with the control group after treatment，the experimental group presented significantly increased functional scores （physical function，emotional function，social function，and overall health） （P<0.05） and significantly reduced symptom scores （fatigue，nausea and vomiting，shortness of breath，loss of appetite，and diarrhea） of the EORTC QLQ-C30 scale （P<0.05）. Compared with those before treatment，the traditional Chinese medicine syndrome scores （eating too little and poor digestion，fatigue and weakness，postprandial bloating，abnormal bowel movements，lassitude and weakness，and total score） in the experimental group were significantly reduced （P<0.05）. Compared with the control group after treatment，the experimental group had significantly reduced traditional Chinese medicine syndrome scores （eating too little and poor digestion，fatigue and weakness，nausea and vomiting，and sallow complexion） （P<0.05）， which indicated better efficacy in the experimental group than in the control group （χ²=7.996，P<0.05）. The serum levels of TNF-α，IL-6，and IFN-γ were significantly correlated with each other （P<0.01）. Compared with those before treatment，the levels of serum cytokines TNF-α，IL-6，and IFN-γ in the experimental group were significantly reduced （P<0.05）. Compared with the control group after treatment，the experimental group showed significantly reduced serum levels of cytokines TNF-α，IL-6，and IFN-γ （P<0.05）. ③ There were no significant intra-group and inter-group differences in the safety test results of the two groups before and after treatment. During the treatment period，there was no significant difference in the incidence of adverse reactions between the two groups of patients. ④ Compared with the normal group，the tumor group exhibited a total of 328 significantly up-regulated genes in the peripheral blood （P<0.05），and KEGG and GO analyses showed that they were significantly enriched in signaling pathways such as TNF （P<0.05）. ⑤ TNF，IL6，IFNG， and other cytokine encoding genes may be key pathogenic genes for CRF. ConclusionXu's SQYZ decoction can alleviate symptoms such as fatigue in postoperative chemotherapy patients with gastric cancer and improve their functional status and quality of life. Its mechanism may be related to improving cytokine imbalance.

Background::Cardiovascular disease (CVD) has emerged as the leading cause of death from prostate cancer (PCa) in recent decades, bringing a great disease burden worldwide. Men with preexisting CVD have an increased risk for major adverse cardiovascular events when treated with androgen deprivation therapy (ADT). The present study aimed to explore the prevalence and risk evaluation of CVD among people with newly diagnosed PCa in China.Methods::Clinical data of newly diagnosed PCa patients were retrospectively collected from 34 centers in China from 2010 to 2022 through convenience sampling. CVD was defined as myocardial infarction, arrhythmia, heart failure, stroke, ischemic heart disease, and others. CVD risk was estimated by calculating Framingham risk scores (FRS). Patients were accordingly divided into low-, medium-, and high-risk groups. χ2 or Fisher’s exact test was used for comparison of categorical variables. Results::A total of 4253 patients were enrolled in the present study. A total of 27.0% (1147/4253) of patients had comorbid PCa and CVD, and 7.2% (307/4253) had two or more CVDs. The enrolled population was distributed in six regions of China, and approximately 71.0% (3019/4253) of patients lived in urban areas. With imaging and pathological evaluation, most PCa patients were diagnosed at an advanced stage, with 20.5% (871/4253) locally progressing and 20.5% (871/4253) showing metastasis. Most of them initiated prostatectomy (46.6%, 1983/4253) or regimens involving ADT therapy (45.7%, 1944/4253) for prostate cancer. In the present PCa cohort, 43.1% (1832/4253) of patients had hypertension, and half of them had poorly controlled blood pressure. With FRS stratification, as expected, a higher risk of CVD was related to aging and metabolic disturbance. However, we also found that patients with treatment involving ADT presented an originally higher risk of CVD than those without ADT. This was in accordance with clinical practice, i.e., aged patients or patients at advanced oncological stages were inclined to accept systematic integrative therapy instead of surgery. Among patients who underwent medical castration, only 4.0% (45/1118) received gonadotropin releasing hormone antagonists, in stark contrast to the grim situation of CVD prevalence and risk.Conclusions::PCa patients in China are diagnosed at an advanced stage. A heavy CVD burden was present at the initiation of treatment. Patients who accepted ADT-related therapy showed an original higher risk of CVD, but the awareness of cardiovascular protection was far from sufficient.

OBJECTIVE To construct a clinical model of motion sickness(MS),provide a relatively objective diagnostic model for MS research,and provide a basis for further clinical intervention of the disease.METHODS A total of 60 subjects were included and divided into experimental group and control group according to the presence or absence of MS.The MS clinical model was established using SRM-IV rotating chair.Peripheral blood was collected before and after acceleration exposure,and the contents of adrenocorticotropic hormone(ACTH),growth hormone(GH),prolactin(PRL),follicle stimulating hormone(FSH),luteinizing hormone(LH),thyroid stimulating hormone(TRH)and gastrin-17(G-17),acetylcholine(ACH)and 5-hydroxytryptamine(5-HT)were detected,Graybiel scale was used to evaluate the severity of MS.The correlation between MS symptoms and signs and peripheral blood indexes was analyzed by multiple linear regression,and the diagnostic model was established.construct a clinical model of MS and a diagnostic model based on blood parameters,so as to provide a reliable clinical model and an objective diagnostic model for MS research,and to provide a basis for further clinical intervention of the disease.RESULTS After acceleration exposure,the Graybiel scores,ACH,5-HT,ACTH,GH and PRL levels in peripheral blood of the experimental group were higher than those before exposure,and were significantly different from those of the control group(P<0.001).There was no significant difference in FSH,LH,TRH and G-17 between the two groups before and after acceleration exposure(P>0.05).Multi-index combined diagnostic model:Graybiel scores=-9.32+0.131×ACTH+0.055×ACH+0.041×5-HT.CONCLUSION The levels of ACH,5-HT,ACTH,GH and PRL increased during the onset of MS.The multi-index combined diagnosis model can provide a certain basis for the objective diagnosis of MS in clinical practice.

Myelodysplastic syndrome(MDS)is a malignant clonal disease with high heterogeneity in cytogenetics and molecular genetics,and the risk of progression to acute myeloid leukemia(AML)is extremely high.Transforming growth factor-β(TGF-β)is closely related to the pathogenesis of MDS.It is a key executor of immune homeostasis and immune tolerance,and can inhibit the expansion and function of many components of immune system.TGF-β signaling pathway can regulate hematopoietic cells and immune cells in microenvironment,inhibit their normal biological functions,and thus accelerate the progression of MDS.This study reviews regulatory effects of TGF-β signaling pathway on MDS blood cells,T lymphocytes,natural killer cells and macrophages in recent years,and provides a new perspective for the pathogenesis and treatment of MDS.

Objective:To compare the clinical efficacy of axillary transthoracic approach and posterior approach in the treatment of upper thoracic tuberculosis with vertebral clearance, bone graft fusion, and internal fixation surgery.Methods:Fifty five patients with upper thoracic tuberculosis admitted to Changsha Central Hospital, University of South China from March 2017 to March 2022 were selected and divided into axillary transthoracic group and posterior group according to different surgical approaches. The incision length, surgical time, intraoperative blood loss, and postoperative hospitalization time were compared between the two groups of patients. Two groups of patients were recorded for preoperative and postoperative pain visual analog scale (VAS) scores, Oswestry Disability Index (ODI) scores at 1 week, 3 months, and 12 months, preoperative and postoperative serum inflammatory indicators, CD4 + /CD8 + ratio of T lymphocyte subsets, and complications. Results:The incision length, operation time, and intraoperative blood loss in the axillary transthoracic group were significantly less than those in the posterior group, and the differences were statistically significant (all P<0.05). However, there was no statistically significant difference in postoperative hospitalization time between the two groups of patients ( P>0.05). The VAS and ODI scores of the two groups of patients showed significant improvement compared to preoperative levels at 1 week, 3 months, and 12 months after surgery (all P<0.05); And at 1 week and 3 months after surgery, the VAS scores of patients in the axillary transthoracic group were significantly lower than those in the posterior group (all P<0.05), and the ODI scores at 3 and 12 months after surgery were significantly lower than those in the posterior group (all P<0.05). The erythrocyte sedimentation rate and CRP levels of both groups of patients increased significantly one week after surgery compared with preoperative levels (all P<0.05), but the erythrocyte sedimentation rate and CRP levels basically returned to normal levels at three months after surgery. The CD4 + /CD8 + ratio of T lymphocyte subsets in both groups was lower than preoperative levels at one week after surgery, but with the continuation of treatment, the CD4 + /CD8 + ratio increased significantly at three months after surgery. Conclusions:Both axillary and posterior approaches can be used for surgical treatment of upper thoracic tuberculosis, but axillary and thoracic approaches have the advantages of less trauma, less bleeding, and faster recovery.

Polymorphism refers to the simultaneous and frequent existence of two or more discontinuous variants or genotypes or alleles in a biological population, also known as genetic polymorphisms or genes Polymorphism. This gene polymorphism may have a certain degree of influence on the pharmacokinetics and pharmacodynamics of the drug. The study of genomics plays an important role in realizing personalized, patient-oriented precision medicine treatment. Population model analysis is to use a modeling method to quantitatively describe the correlation and variability between pharmacokinetic and pharmacodynamic parameters and individual characteristics and to quantify the impact of covariates. At present, this method has been widely used. This paper systematically introduces the application examples of using the population model approach to assess the effects of genetic polymorphisms on the drug PK/PD.

Central nervous system （CNS） is a sophisticated system subject to complex regulation， which dominates the high-level neural activities of the human body. Due to its complex physiological structure and refined regulatory mechanism covering a variety of diseases， CNS is the place where many chronic， refractory and rare diseases occur. Nerve cell is the basic unit of CNS， and its dysfunction and death is the root cause of CNS diseases. Ferroptosis is a new form of programmed cell death proposed in recent years， and has been proved to be closely related to the production and development of multiple CNS diseases. Traditional Chinese medicine （TCM）， including Chinese herbs， acupuncture and moxibustion， and massage， has shown unique advantages in the treatment of CNS diseases for a long time. A large number of studies have demonstrated that TCM participates in the regulation of CNS diseases via regulating ferroptosis and shows a good research prospect. This paper summarized the characteristics of ferroptosis and discussed the association between ferroptosis and CNS diseases in pathological mechanism. We also reviewed the regulation of various CNS diseases by different TCM interventions through ferroptosis， providing references for TCM to participate in the treatment of CNS diseases properly in the future.

Objective:To investigate the clinical efficacy and safety of demethylating drugs decitabine and azacitidine in treatment of myelodysplastic syndromes (MDS).Methods:The clinical data of 15 patients initially diagnosed with MDS in Fujian Provincial Hospital from May 2010 to May 2020 were retrospectively analyzed; 10 patients were treated with decitabine (10-30 mg·m -2·d -1, 3-5 d consecutively) and 5 patients were treated with azacitidine (75 mg·m -2·d -1 for 7 d consecutively). Gene mutation, risk stratification, efficacy and adverse reactions were observed. Results:Among 15 patients, 9 cases were males and 6 cases were females, with a median age of 64 years (51-84 years). The median follow-up time was 18 months (4-62 months). There were 3 cases in high-risk group, 10 cases in medium-risk group and 2 cases in low-risk group. SF3B1, TET2 and STAG2 mutations were more common in patients with low to moderate risk; DNMT3A, EZH2, U2AF1, RUNX1 and TP53 mutations were more common in patients with high-risk. All patients were evaluated for efficacy after 2-3 courses of treatment, and the total effective rate was 66.7% (10/15). Among them, 1 case (6.7%) achieved complete remission, 1 case (6.7%) achieved bone marrow complete remission (mCR), 2 cases (13.3%) achieved partial remission, and 6 cases (40%) achieved hematological improvement. During the treatment, 9 cases had grade 3-4 hematological toxicity and 6 cases had grade 3-4 infection. There was no grade 3-4 bleeding, nausea, vomiting and liver function damage. During the follow-up to May 2020, 9 patients survived and 6 patients died.Conclusions:Demethylating drugs decitabine and azacitidine have high rates of complete remission and partial remission and a low rate of adverse drug reactions in MDS patients.

Objective:To investigate the effect of CHI3L1 on the biological function of chondrocytes and its role in lumbar facet joint degeneration.Methods:The human lumbar facet joint articular cartilage were collected, and the relative mRNA expression of CHI3L1 gene detected by quantitative fluorescence PCR. Then explored the correlation between joint degeneration and gender, age and relative mRNA expression of CHI3L1. Human chondrocytes were cultured in vitro. The effects of CHI3L1 on chondrocyte proliferation, cycling, and apoptosis, as well as expression of related inflammatory factors, were investigated. The mechanism by which CHI3L1 regulates the degeneration of articular cartilage was investigated using the signal transduction pathway protein chip.Results:There was a positive correlation between the grade of degeneration in lumbar facet joint and the relative expression of CHI3L1 gene mRNA ( r=0.76, P<0.001). There was no correlation with the patient's gender ( r=-0.12, P=0.500). A positive correlation between the age of patients and the relative expression of CHI3L1 gene mRNA was found ( r=0.47, P=0.005). Compared with the non-degenerative group, the expression of CHI3L1 gene mRNA significantly increased in the degenerative group, and the expression of CHI3L1 gradually increased with the aggravation in the grade of degeneration ( F=18.90, P<0.001). Compared with the non-degenerative group, the chondrocytes in the CHI3L1 group had significantly lower proliferation at 48 h (OD 490/fold=7.132), 72 h (OD 490/fold=4.803), 96 h (OD 490/fold=2.431) and 120 h (OD 490/fold=0.009). The ratio of chondrocytes in G1 phase, S phase and G2/M phase were 85.03%±3.05%, 12.78%±2.29% and 0.90%±0.76% in the CHI3L1 group, and 73.93%±2.73%, 22.81%±1.93% and 0.99%±0.87% in control group, respectively. There were significant differences in the percentage of chondrocytes in G1 phase ( t=4.70, P<0.001) and S phase ( t=5.80, P<0.001) between the two groups. The percentages of apoptosis in chondrocyte in CHI3L1 group and control group were 8.64%±0.76% and 5.68%±1.13%, which has a statistically difference ( t=4.47, P<0.001). The expression of IL-6 in chondrocytes of CHI3L1 group was 49.60±0.01 pg/ml, which was higher than that of 47.88±0.01 pg/ml in the control group ( t=132.70, P<0.001). The expression of TNF-α was 95.93±0.02 pg/ml, which was higher than 90.69±0.02 pg/ml in the control group ( t=376.10, P<0.001). There was significant difference in expression of IL-6 in chondrocytes between the CHI3L1 group and the control group ( t=132.72, P<0.001). The expression of TNF-α ( t=376.10, P<0.001) was statistically difference. Protein chip detected 53 proteins with significant differences in expression and 43 proteins with significant differences in protein phosphorylation levels. Bioinformatics analysis was used to identify 16 signaling pathways in which the above different proteins might be involved, including ErbB, PI3K, Akt, Ras, JAK, STAT3, MAPK pathway. In the MAPK pathway, the expression of MAPK1 and RAF1 proteins was higher in the chondrocytes of the CHI3L1 group than in the control group (1.094±0.00 vs. 0.814±0.00, 0.988±0.00 vs. 0.786±0.00; t=103.16, P<0.001; t=54.32, P<0.001). Compared with the control group, the expression of MAPK1 and RAF1 proteins was significantly increased in the chondrocytes of the CHI3L1 group. Conclusion:The expression of CHI3L1 is corrected to articular cartilage degeneration. CHI3L1 is able to inhibit the proliferation of articular chondrocytes, which regulated the cycling of chondrocytes from G1 phase to S phase, promote the apoptosis of chondrocytes, and promote the expression of IL-6 and TNF-α in chondrocytes. Regulation of chondrocytes biological function through the MAPK pathway, which is a potential biomarker for the clinical diagnosis and treatment of lumbar joint degeneration.

Objective:To evaluate the clinical effect of anterior clinoid process grinding in the treatment of ophthalmic / superior clinoid process aneurysms and sellar tumors.Methods:The clinical data of 16 patients who underwent anterior clinoid process grinding in Sanbo Brain Hospital, Capital Medical University from January 2015 to July 2021 were analyzed retrospectively. There were 1 patient with recurrent craniopharyngioma, 1 patient with recurrent pituitary adenoma, 13 patients with aneurysms, and 1 patient with suprasellar granulosa cell tumor combined with ophthalmic aneurysm of right internal carotid artery. The Modified Rankin Scale (mRS) score was used to evaluate the situation at discharge and in the medium-and-long term.Results:Sixteen patients underwent anterior clinoidprocess grinding. At discharge and the latest follow-up, the mRS scores of the patients were 0-2. A total of 15 aneurysms were treated, and there were no symptoms of visual loss or visual field defect after operation. No cerebrospinal fluid leakage occurred in all patients.Conclusions:The grinding of anterior clinoid process can effectively and fully stretch the optic nerve and internal carotid artery, and can observe the tumor neck at the lower end of pituitary stalk and the ocular segment/superior clinoid process of internal carotid artery under direct vision. It is one of the important auxiliary methods for the treatment of sellar lesions.
