ABSTRACT
OBJECTIVE@#To observe the effects of Tiaoshen (regulating the spirit) acupuncture on cognitive function and sleep quality in patients with primary insomnia (PI).@*METHODS@#Sixty patients with PI were randomly divided into an observation group (30 cases, 2 cases dropped off) and a control group (30 cases, 2 cases dropped off, 1 case was excluded). The patients in the observation group were treated with acupuncture at Baihui (GV 20), Shenting (GV 24), Sishencong (EX-HN 1), and bilateral Benshen (GB 13), Shenmen (HT 7), Neiguan (PC 6), Sanyinjiao (SP 6). The patients in the control group were treated with shallow needling at non-effective points. Each treatment was provided for 30 min, once every other day, 3 treatments per week for 4 weeks. The Montreal cognitive assessment (MoCA), digit span test (DST), trail making test (TMT)-A, Pittsburgh sleep quality index (PSQI), and fatigue scale-14 (FS-14) were used to assess cognitive function and sleep quality before and after treatment, as well as in follow-up of 4-week after treatment completion. Correlation analysis was conducted between the differences in PSQI scores and differences in MoCA scores before and after treatment in the observation group.@*RESULTS@#Compared with before treatment, the total score, visuospatial and executive function score and delayed memory score of MoCA as well as DST backward score were increased (P<0.01), while TMT-A time, PSQI and FS-14 scores were significantly reduced (P<0.01) after treatment and in follow-up in the observation group. Compared with before treatment, the PSQI score in the control group was reduced (P<0.01, P<0.05). After treatment and in follow-up, the observation group had significantly higher total score, visuospatial and executive function score, delayed memory score of MoCA, and DST backward score compared to the control group (P<0.05, P<0.01). In the observation group, the TMT-A time was significantly shorter than that in the control group (P<0.05, P<0.01), and the PSQI and FS-14 scores were significantly lower than those in the control group (P<0.01). In the observation group, there was a negative correlation between the difference in PSQI scores (post-treatment minus pre-treatment) and the difference in MoCA scores (post-treatment minus pre-treatment) (r=-0.481, P<0.01). A similar negative correlation was found between the difference in PSQI scores (follow-up minus pre-treatment) and the difference in MoCA scores (follow-up minus pre-treatment) (r=-0.282, P<0.05).@*CONCLUSION@#Tiaoshen acupuncture could improve cognitive function, enhance sleep quality, and alleviate daytime fatigue in patients with PI. The improvement in cognitive function in patients with PI is correlated with the improvement in sleep quality.

Objective To investigate the impact of PD1-TCF1+CD8+ stem-like memory T cells on immunotherapy prognosis and tertiary lymphoid structure in tumors. Methods Pathological tissue sections were collected from 33 patients treated with immunotherapy, 18 cases of NSCLC and 15 cases of ESCC. The expression of PD1-TCF1+CD8+T cells was detected through quantitative analysis by multiplex immunofluorescence. Survival curves were described by the Kaplan-Meier method. Pearson's correlation test was used for correlation analysis. Results The high levels of PD1-TCF1+CD8+T cells had a better PFS in NSCLC and ESCC cohorts. In the NSCLC cohort, high levels of PD1-TCF1+CD8+ T cells were significantly and positively correlated with the number (P=0.0151) and size (P=0.0007) of TLSs. Conclusion In patients with NSCLC and ESCCs, high PD1-TCF1+CD8+ stem-like memory T cell expression indicates improved prognosis and immune response and is associated with the formation of TLSs in the tumor microenvironment of NSCLC.
ABSTRACT
Objective To explore the effect of peripheral blood markers on the efficacy and prognosis of patients with advanced esophageal cancer treated with immune checkpoint inhibitors (ICIs). Methods The case data of 61 patients with advanced esophageal cancer who met the inclusion criteria were collected. Data on clinical indicators and peripheral blood markers as well as objective response rate (ORR) and progression-free-survival (PFS) were obtained. Results The median PFS of the included patients was 7.10 months (95%CI: 5.12-9.07). The ORR of patients with baseline lactate dehydrogenase (LDH) < 201 was better than that of patients with LDH≥201 (P < 0.05). Univariate analysis showed that baseline LDH0 < 201, neutrophil to lymphocyte ratio (NLR) < 3.9, platelet-to-lymphocyte ratio (PLR) < 240.3, and LDH1 < 249.0 two weeks after ICI treatment were significantly associated with significant improvement in PFS (P < 0.05). In multivariate analysis, patients with NLR0 < 3.9 had longer PFS (P < 0.05). Conclusion LDH0 < 201, NLR0 < 3.9, PLR0 < 240.3, and LDH1 < 249.0 are positively correlated with the prognosis of patients with advanced esophageal cancer treated with ICIs.
ABSTRACT
Aim To explore the main active ingredients of Tripterygium wilfordii and the mechanism in treat-ment of breast cancer based on network pharmacology.Methods The active components and targets of Tripterygii Wilfordii were searched by TCMSP.GeneCard database was used to screen the potential targets of Tripterygii Wilfordii in treatment of breast cancer.The two were matched to obtain the core components and targets of Tripterygii Wilfordii.Cytoscape3.6.0 and AutoDock Vina were used to draw the drug-target network diagram, and GO enrichment analysis, KEGG pathway enrichment analysis, and molecular docking between the core target and the components were carried out.CCK8 and qPCR were used to verify the effect of optimal core component tripterine on breast cancer cells.Results Seven kinds of active anti-breast cancer components and twenty-five core therapeutic targets of Tripterygii Wilfordii were obtained.Tripterine, which significantly inhibited the growth of breast cancer cells, was the most valuable component of Tripterygii Wilfordii for breast cancer.QPCR results showed that tripterine decreased the expression of core therapeutic targets.Conclusions The effectiveness of Tripterygii Wilfordii has multiple pathways, and tripterine may play an important role in treatment of breast cancer.
ABSTRACT
The emergence of immune checkpoint inhibitors (ICIs) has greatly changed the treatment strategy of non-small cell lung cancer (NSCLC). Although ICIs are effective, there are still many patients who cannot benefit from immunotherapy alone. The current research direction focuses on the combination of multiple treatment schemes. Radiotherapy can upregulate immunogenic cell surface markers, and regulate the expressions of immune checkpoints. A large number of preclinical and clinical studies are exploring the efficacy and safety of ICIs combined with radiotherapy in various clinical stages of NSCLC, including radiotherapy timing, optimal dose, dose distribution and so on.

ABSTRACT
The present study investigated the effects of chikusetsu saponin Ⅳa(CHS Ⅳa) on isoproterenol(ISO)-induced myocardial hypertrophy in rats and explored the underlying molecular mechanism. ISO was applied to establish a rat model of myocardial hypertrophy, and CHS Ⅳa(5 and 15 mg·kg~(-1)·d~(-1)) was used for intervention. The tail artery blood pressure was measured. Cardiac ultrasound examination was performed. The ratio of heart weight to body weight(HW/BW) was calculated. Morphological changes in the myocardial tissue were observed by HE staining. Collagen deposition in the myocardial tissue was observed by Masson staining. The mRNA expression of myocardial hypertrophy indicators(ANP and BNP), autophagy-related genes(Atg5, P62 and beclin1), and miR199 a-5 p was detected by qRT-PCR. Atg5 protein expression was detected by Western blot. The results showed that the model group exhibited increased tail artery blood pressure and HW/BW ratio, thickened left ventricular myocardium, enlarged myocardial cells, disordered myocardial fibers with widened interstitium, and a large amount of collagen aggregating around the extracellular matrix and blood vessels. ANP and BNP were largely expressed. Moreover, P62 expression was up-regulated, while beclin1 expression was down-regulated. After intervention by CHS Ⅳa at different doses, myocardial hypertrophy was ameliorated and autophagy activity in the myocardial tissue was enhanced. Meanwhile, miR199 a-5 p expression declined and Atg5 expression increased. As predicted by bioinformatics, Atg5 was a target gene of miR199 a-5 p. CHS Ⅳa was capable of preventing myocardial hypertrophy by regulating autophagy of myocardial cells through the miR-199 a-5 p/Atg5 signaling pathway.

ABSTRACT
Human papillomavirus (HPV) is a major causative agent of head and neck squamous cell carcinomas (HNSCC). Over the past several decades, an increasing number of studies established the strong association of HPV with the invasion and metastasis of HNSCC. In the present study, we reviewed the gene mutations in HPV-associated HNSCC and the unique mechanism of E6- and E7-mediated carcinogenesis via interactions with an array of cellular elements. We further discussed the progress in the mechanisms of invasion and metastasis; these mechanisms include non-coding RNAs, deregulating cellular energetics, tumor microenvironment, cancer stem cells, angiogenesis, and lymphangiogenesis.

ABSTRACT
Objective To observe the clinical efficacy of wheat-sized moxibustion in assisting the treatment of mild—to-moderate persistent chronic bronchial asthma in the elderly with Salmeterol xinafoate and fluticasone propionate aerosol. Method Eighty-four old patients with mild—to-moderate persistent chronic bronchial asthma were randomized into an observation group and a control group by using the random number table, 42 each. The control group was given Salmeterol xinafoate and fluticasone propionate aerosol, 1 inhalation each time, twice a day;the observation group was additionally given wheat-sized moxibustion by selecting Pishu (BL20), Feishu (BL13) and Geshu (BL17), twice a week. The two groups were both treated for 2 months. Before and after the intervention, Asthma Control Test (ACT), Asthma Quality of Life Questionnaire (AQLQ), and pulmonary function parameters [peak expiratory flow (PEF), forced expiratory volume in one second (FEV1), and forced vital capacity (FVC)] were observed, and the clinical efficacies were compared. Result The total effective rate was 92.9% in the observation group versus 78.6% in the control group, and the difference was statistically significant (P<0.05); the ACT and AQLQ scores, as well as PEF, FEV1 and FVC were significantly increased after the intervention in both groups (P<0.05); after the treatment, the improvement in the observation group was significantly superior to that in the control group (P<0.05). Conclusion Wheat-sized moxibustion is effective in assisting the treatment of mild-to-moderate persistent chronic bronchial asthma in the elderly with Salmeterol xinafoate and fluticasone propionate aerosol. It can effectively controlasthma and enhance the quality of life.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the anti-aging effect of artemisia burning products (ie. smoke of moxibustion) and its proper intervention parameters.</p><p><b>METHODS</b>According to factorial experiment design, 70 SAMP8 mice were randomly divided into one model group (group M) and 6 intervention groups: low concentration with 15 min group (group A1), low concentration with 30 min group (group A2), middle concentration with 15 min group (group B1), middle concentration with 30 min group (group B2), high concentration with 15 min group (group C1), high concentration with 30 min group (group C1). There were 10 cases in each group. Ten age-matched SAMR1 mice were used as normal group (group Z). All the mice in the 6 intervention groups were fumed with artemisia burning products of different concentration and time. The content of serum malondialdehyde (MDA), the activity of superoxide dismutase (SOD) and glutathione reductase (GSH-Px) were tested.</p><p><b>RESULTS</b>MDA content in group M was significantly higher than that in group Z (both P < 0.05), while SOD and GSH-Px activity were significantly lower in group M than that in group Z (both P < 0.05). Results of MDA, SOD and GSH-Px in 6 intervention groups were either of no statistically significant differences, or better than that in group M. Among 6 intervention groups, results of MDA and GSH-Px were better in group B1, while the result of SOD was better in group B2. Time factor didn't make any difference, while concentration of artemisia burning products is meaningful. As to SOD and GSH-Px, there's a strong interaction between the two factors.</p><p><b>CONCLUSION</b>With certain concentration and time period, the intervention of artemisia burning products can exert anti-aging effect by increasing antioxydative capability and reducing metabolites of free radicals. Middle concentration and 30 minutes are recommended when intervened with artemisia burning products.</p>

<p><b>OBJECTIVE</b>To study the role and prospect of 18FDG PET imaging in patients with malignant lymphoma.</p><p><b>METHODS</b>Forty-four patients (73 studies) with malignant lymphoma underwent 18FDG PET imaging. Final diagnoses were proved histopathologically. Images obtained were analyzed using visual and semiquantitative analysis (SUV).</p><p><b>RESULTS</b>Either nodal or extranodal tumor foci showed high 18FDG uptake. 18FDG PET led to correct diagnosis in 5 of 6 cases except 1 false negative case. PET imaging changed the staging in 4 of 6 cases pretherapeutically. Of the 16 cases in which either residual tumor mass or suspicious recurrence suggested by other imaging modalities, 18FDG PET confirmed relapse in 5, detected more lesions in 2 and showed no evidence of active tumor mass in 9. For the 3 patients with comparison between pre- or post-treatment PET imaging and 16 patients who only underwent post-treatment PET follow-up studies, therapeutic response was correctly evaluated.</p><p><b>CONCLUSIONS</b>18FDG PET is a valuable non-invasive metabolic imaging modality in facilitating diagnosis and staging, evaluating therapeutic response, assessing clinical outcome and predicting prognosis in patients with lymphoma.</p>
