Tumors are highly complex systems. Understanding the compositions and functions of the tumor immune microenvironment is a prerequisite for effective tumor immunotherapy. Single-cell RNA sequencing can detect the transcriptome of a cell at the resolution of single-cell level,describe its functional status,and thus deepen the understanding of the composition and function of different cell clusters in tumor immune microenvironment. This article reviews the application of single-cell RNA sequencing in research on tumor immune microenvironment.
ABSTRACT
While immune checkpoint inhibitors(ICIs)are effective and promising treatments for a variety of malignancies,they also have safety concerns,especially the immune-related adverse events(irAEs).Unlike the side effects of traditional chemotherapy and targeted therapy,irAEs are adverse events caused by immune activation after ICIs treatment and thus may involve almost every system of the body.Therefore,biomarkers for predicting irAEs after ICIs treatment are urgently needed.Here we review the currently available predictive biomarkers of irAEs.

Objective To investigate the expression of α-smooth muscle actin(α-SMA)in advanced colorectal cancer tissue and its association with chemotherapy response and prognosis.Methods The expression of α-SMA was detected by immunohistochemistry in tissues from 52 advanced colorectal cancer patients who received oxaliplatin plus 5-fluorouracil regimen as first-line chemotherapy. Its relationship with clinical characteristics,chemotherapy response,and survival were analyzed.Results Of these 52 patients,29(55.8%)were α-SMA overexpression,and the expression of α-SMA protein was not significantly associated with the age(χ =0.113,P=0.730),gender(χ =0.515,P=0.332),tumor location(χ =3.675,P=0.159),and tissue differentiation(χ =1.852,P=0.604). The chemotherapy resistance rate was 65.5%(19/29)in patients with high α-SMA expression,which was significantly higher than that (13.0%,3/23)in patients with low α-SMA expression(χ =14.470,P=0.000). Patients with high α-SMA expression exhibited a significantly shorter progression-free survival(PFS)compared with those with low α-SMA expression [(6.4±1.0)months vs.(16.0±3.5)months; χ=5.985,P=0.018]. Conclusion High α-SMA expression is associated with resistance to first-line chemotherapy and poor prognosis in advanced colorectal cancer patients.

Objective To evaluate the curative effect of Huoxue-Xiaozhi capsule on non-alcoholic fatty liver disease (NAFLD). Methods A total of 100 patients with NAFLD who met the inclusion criteria were divided into 2 groups with 50 patients in each group by random number table method. The treatment group was treated with Huoxue-Xiaozhi capsule, while the control group was treated with Compound Methionine Choline Tablets. Both groups were treated for 8 weeks. The ALT, AST, γ-GT (γ- glutamyltranspeptidase ), ALP (alkaline phosphatase, alkaline phosphate) were detected by automatic blood biochemical analyzer. The serum high sensitivity-C reactive protein (hs-CRP) and Homocysteine (Hcy) were detected by supplementary detection method. The serum IL-18 was detected by ELISA method, and liver imaging was performed before and after treatment. The symptoms and signs were evaluated, and clinical efficacy was evaluated. Results The total effective rate was 90.0％ (45/50) in the treatment group and 74.0％ (37/50) in the control group. The difference between the two groups was statistically significant (Z=-2.328, P=0.020 ). After treatment, the serum hs-CRP (2.4 ± 2.9 mg/L vs. 3.6 ± 2.8 mg/L, t=2.105), Hcy (11.2 ± 5.5 μmol/L vs. 13.9 ± 6.4 μmol/L, t=2.262), IL-18 (690.6 ± 61.3 ng/L vs. 775.4 ± 60.5 ng/L, t=6.962) in the treatment group were significantly lower than those in the control group (P<0.05 or P<0.01). After treatment, the improvement of hypochondriac lump, sallow complexion, dark complexion and hypochondriac dull pain in the treatment group were superior to those in the control group (Z values were -2.563, -2.788, -2.780, -2.220 respectively, all Ps<0.05 ). The Serum ALT, AST,γ-GT and ALP levels were significantly lower than those of the control group (t values were 18.820, 19.811, 10.221 and 3.248 respectively, all Ps<0.001 ). Conclusions The Huoxue-Xiaozhi capsule can improve the liver function and reduce the levels of serum hs-CRP, HCY and IL-18, and its curative effect of NAFLD.

ABSTRACT
Objective: To observe the clinical efficacy of acupuncture plus bloodletting therapy in treating insomnia in people with blood stasis constitution. Methods: Seventy-two patients were randomized into a treatment group and a control group by using the random number table, 36 cases each. The treatment group received acupuncture plus bloodletting therapy, while the control group was intervened by oral administration of estazolam. One-week treatment was taken as a course, for 3 successive courses in total. A follow-up study was conducted 3 months later. The Pittsburgh sleep quality index (PSQI) was evaluated before and after the intervention, as well as in the follow-up. The clinical efficacies were also compared. Results: The total effective rate was 88.9% in the treatment group versus 83.3% in the control group, and the between-group difference was statistically significant (P<0.05). After the intervention, the PSQI scores dropped significantly in both groups (both P<0.05); the between-group difference in PSQI score was statistically significant (P<0.05). The follow-up study showed that the between-group difference in the global score of PSQI was statistically significant (P<0.05). Conclusion: Acupuncture plus bloodletting therapy can produce a more significant efficacy than oral administration of estazolam in treating insomnia in people with blood stasis constitution.

ABSTRACT
Objective: To evaluate the impact of mean platelet volume (MPV) on prognosis in patients with ST-segment elevation myocardial infarction (STEMI). Methods: A total of 1012 consecutive STEMI patients received percutaneous coronary intervention (PCI) in our hospital from 2010-01-01 to 2014-10-31 were enrolled. Major adverse cardiovascular events (MACE) were recorded in 2015-10. Based on ROC curve measured optimal critical point of MPV in all-cause death, the patients were divided into Low MPV group and High MPV group. The incidence of MACE was compared between 2 groups, the impact of MPV on prognosis of PCI treated STEMI patients was studied by uni- and multivariate COX regression analysis. Results: By ROC curve, the optimal critical point of MPV in all-cause death was MPV≤9. 466 fl. MPV≤9. 466 fl in Low MPV group, n=549 and MPV>9. 466 fl in High MPV group, n=463. The patients were followed-up for 34 (12-69) months. Compared with Low MPV group, the patients in High MPV group had the higher incidences of all-cause death and cardiac death, P<0. 001 and P=0. 001. With adjusted multivariates, COX regression analysis showed that MPV was an independent risk factor of all-cause death (HR=1. 463, P<0. 001) and cardiac death (HR=1. 458, P<0. 001) in relevant patients. Conclusions: Increased MPV at admission had the predictive value for long-term prognosis in PCI treated STEMI patients.

ABSTRACT
Objective To investigate the effect of human hepatocellular carcinoma HepG2 cell-derived Exosome on the differentiation of mesenchymal stem cells(MSC)into cancer-associated myofibroblasts(CAF)and the impacts of CAF on liver cancer cell proliferation,migration,and invasion. Methods The protein expression of HepG2 cell-derived Exosome was detected by Western blotting. MSCs were separated from human adipose tissue and cultured with HepG2 cell-derived Exosome(100 ng/nl)to initiate differentiation. The expressions of mesenchymal markers and several interleukins were also detected by Western blotting. HepG2 cells were co-cultured with the conditioned media(CM),in which HepG2 Exosome induced the differentiation of MSC into CAF. The expressions of epithelial and mesenchymal markers were detected by real-time polymerase chain reaction(PCR)and Western blotting. Cell proliferation was assessed using MTS assay. Transwell chambers were used in the in vitro migration and invasion assay. Results HepG2 cell-derived particles expressed CD63,70 kilodalton heat shock proteins,and 90 kilodalton heat shock proteins. With the treatment of HepG2 cell-derived Exosome,the expressions of mesenchymal marker α-smooth muscle actin,fibroblast activation protein α,interleukin(IL)-6,IL-8,and IL-1β were up-regulated,while vascular endothelial growth factor had no significant change. The conditioned media which HepG2 Exosome induced MSC differentiation CAF(CAF-CM)could significantly promote HepG2 cells proliferation(1.075±0.104),compared to BSA control(0.874±0.066,P=0.023)and MSC-CM(0.649±0.034,P=0.0005). CAF-CM could significantly enhance cell migration [(42.5±9.1) cells vs.(18.5±3.1) cells,P=0.001] and invasion [(29.0±3.5) cells vs.(13.1±3.7) cells,P=0.009] compared to its control group. Moreover the conditioned medium which HepG2 Exosome induced MSC to differentiate into CAF could also promote the expressions of mesenchyme-related genes Smad interacting protein 1(P=0.040),β-catenin(P=0.038),fibronectin(P=0.029),and Vimentin(P=0.013)and inhibit the expression of epithelial related genes zonula ocdudens-1(P=0.010).Conclusions Exosome extracted from HepG2 cells can induce human adipose-derived MSC to differentiate into cancer-associated myofibroblasts. CAF-like cells can promote the migration of the liver cancer cell line HepG2.

Results After treatment for 45 days, compared with control group, the thyroid nodule in TCM treatment group was significantly shrunken (mm: 8.75±3.41 vs. 15.89±4.51, P < 0.05) , and TCM syndrome score in TCM treatment group was significantly lowered (20.35±4.83 vs. 35.53±6.71, P < 0.05); before and after admission in the two groups, the thyroid function indexes of thyrotropic-stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4) were in the normal range, and there were no statistical significant differences between the two groups (all P > 0.05); the levels of serum VEGF, IGF-I were reduced in the TCM treatment group [VEGF (ng/L): 27.52±8.35 vs. 33.08±9.57, IGF-Ⅰ (μg/L): 24.12±6.74 vs. 35.57±11.39], TGF-β1 was increased in the TCM treatment group (ng/L: 363.67±97.83 vs. 225.87±47.71), and the differences were statistically significant (all P < 0.05). Conclusions Xiaozhong Sanjie decoction combined with Huayu powder external application can inhibit the levels of VEGF, IGF-Ⅰ and elevate the TGF-β1 level that possibly the mechanism of the combined therapy to shrink the thyroid nodule size.
ABSTRACT
<p><b>OBJECTIVE</b>To detect KLF17 expression in colorectal carcinoma (CRC) and to evaluate its effect on the prognosis of colorectal carcinoma.</p><p><b>METHODS</b>Immunohistochemistry was performed to detect the expression of KLF17 in CRC and matched pericarcinous tissue,and the relationship between KLF17 expression and disease-free survival (DFS) was analyzed.</p><p><b>RESULTS</b>Of 73 CRC patients, KLF17 expression was positive in 32 patients and negative in 41 patients. KLF17 expression rate was significantly lower in CRC tissue than in pericarcinous tissue (χ(2)=12.418, P=0.001). The DFS of KLF17-positive stage III colon cancer patients was (56.3±7.2) months (95% CI: 42-70 months), which was significantly longer than that [(32.3±5.5) months (95% CI: 22-43 months)] of KLF17-negative patients (P=0.039).</p><p><b>CONCLUSION</b>KLF17 expression decreases in CRC tissue, and a positivie KLF17 expression predicts a better prognosis in stage III CRC patients.</p>

Objective To discuss the effects of electroacupuncture intervention in different acupoints of rats models with diarrhea type irritable bowel syndrome (D-IBS).Methods The rat models were established with acute and chronic stimulation. The rats were divided into the normal control group, model group, “Taichong” (LR3) + “Zusanli” (ST36) group, and “Tianshu” (ST25) + “Zusanli” (ST36) group. Electroacupuncture was applied to bilateral corresponding acupoints for 20 minutes, every other day for 7 times. The physical signs of each rat were observed. The contents of 5-HT, NE and CGRP in the rats’ plasma were detected by sandwich ELISA. Results Compared with the normal group, the contents of 5-HT and NE in the model group were obviously higher and the content of CGRP decreased (P<0.05). Compared with the model group, the contents of 5-HT and NE in all treatment groups were lower and the content of CGRP increased (P<0.05). There was no difference between the “Taichong” (LR3) + “Zusanli” (ST36) and “Tianshu” (ST25) + “Zusanli” (ST36) groups.Conclusion The mechanism of electroacupuncture may be realized through lowering the contents of 5-HT and NE in the model rats and increasing the content of CGRP to treat D-IBS.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of different concentrations of lipopolysaccharide (LPS), tumor necrosis factor α (TNFα), interleukin-6 (IL-6), dexamethasone (Dex), and insulin on the mRNA and protein expressions of GPR54 in the MCF7 cell line in vitro.</p><p><b>METHODS</b>MCF7 breasr cancer cells were cultured and treated with different concentrations of LPS (10 and 20 µg/ml), TNFα (20 and 100 ng/ml), IL-6 (10 and 20 ng/ml), Dex (10(-6) and 10(-7) mol/L), and insulin (0.01 and 0.1 IU/L). Those treated with culture fluid only served as controls. The mRNA and protein expressions of GPR54 were measured by real-time PCR and Western blot, respectively, after 6, 24, 48, and 72 hours of treatment.</p><p><b>RESULTS</b>Compared with the blank con- trol, LPS (10 and 20 µg/ml), TNFα (20 and 100 ng/ml), IL-6 (10 and 20 ng/ml), Dex (10(-6) and 10(-7) mol/L), and insulin (0.01 and 0.1 IU/L) significantly increased the expressions of GPR54 mRNA (P < 0.05) and protein (P < 0.05).</p><p><b>CONCLUSION</b>LPS, TNFα, IL-6, Dex, and insulin evidently increase the expression of GPR54 in the MCF7 cell line, indicating their influence on the function of gonads by regulating the GPR54 level.</p>
