A new mode for the diagnosis of angioimmunoblastic T-cell lymphoma.

In order to explore a new mode for the diagnosis of angioimmunoblastic T-cell lymphoma (AITL), 31 cases of AITL and 28 cases of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) were used as the study subjects. Identifying T follicular helper (TFH) cells with CD4, CD10, Bcl-6, and PD-1, identifying proliferative B cells with CD20 and EZH2, identifying proliferative follicular dendritic cells (FDCs) with CD21 and CD23, and analyzing the value of TFH/B/FDC proliferation and immunolocalization in the diagnosis of AITL. (1) Outside the inherent lymphoid follicles, simultaneous proliferation of TFH/B/FDC (a new diagnostic mode) were observed in AITL [83.87%; 26/31], with their immunolocalizations in the same site [83.87%; 26/31], while this phenomenon was not observed in 28 cases of PTCL-NOS (P<0.05). (2) The sensitivity and specificity of using this new mode to diagnose AITL were both high (83.87%, 100%), which was superior to CD2 (100%, 0%), CD3 (100%, 0%), CD4 (100%, 32.14%), CD5 (100%, 25%), CD10 (61.9%, 100%), Bcl-6 (42.86%, 100%), PD-1 (83.87%, 96.43%), and its Youden Index (0.84) was the highest. The areas under the curve (AUC) of CD10, Bcl-6, PD-1, and new mode to diagnosis AITL were 0.81, 0.71, 0.90, and 0.92, respectively, while the new mode had the highest AUC. The simultaneous proliferation of TFH/B/FDC cells outside the inherent lymphoid follicles can be used to assist in the diagnosis of AITL, and the simultaneous spatiotemporal proliferation of TFH/B/FDC cells is a specific immunomorphology of AITL.

[Clinical Significance of Genetic and Molecular Changes in Primary Myeloid Sarcoma].

OBJECTIVE: To investigate the clinical significance of genetic and molecular changes in primary myeloid sarcoma (MS). METHODS: Fourteen patients with primary MS were selected in Jiading District Central Hospital Affiliated Shanghai University of Medicine & Health Sciences, The First People's Hospital of Lianyungang from September 2010 to December 2021. AML1-ETO fusion, PML-RARα fusion and CBFß breakage were detected by fluorescence in situ hybridization (FISH), and the mutations of NPM1, CEBPA, FLT3, RUNX1, ASXL1, KIT and TP53 genes were detected by new generation sequencing (NGS). RESULTS: Among 14 patients, the MS occurred in bone, breast, epididymis, lung, chest wall, cervix, small intestine, ovary, lymph nodes and central nervous system. The tumor cells expressed MPO (13 cases), CD34 (7 cases), CD43 (8 cases), CD68 (7 cases), CD99 (8 cases) and CD117 (6 cases). Cytogenetic abnormalities were observed in 4 cases, including 3 cases of AML1-ETO fusion and 1 case of CBFß breakage, while no PML-RARα fusion was detected. There were no significant differences in overall survival (OS) and leukemia-free survival (LFS) between patients with and without AML1-ETO fusion/CBFß breakage (both P >0.05). Among the 14 patients, the number of NPM1, CEBPA, FLT3-ITD, RUNX1, ASXL1, KIT and TP53 gene mutations was 5, 3, 5, 3, 2, 2, 1, respectively, of which 7 cases had at least one mutation in FLT3-ITD, RUNX1, ASXL1 and TP53 gene. The OS and LFS of patients with FLT3-ITD, RUNX1, ASXL1 or TP53 mutation were shorter than those without mutations (both P <0.01). CONCLUSION: The genetic and molecular abnormalities of primary MS can be detected by FISH and NGS techniques. FLT3-ITD, RUNX1, ASXL1 or TP53 mutation indicates a worse prognosis, but further clinical studies are needed to confirm it.

Relationship of HIF­1α expression with apoptosis and cell cycle in bone marrow mesenchymal stem cells from patients with myelodysplastic syndrome.

Myelodysplastic syndrome (MDS) is a group of abnormal clonal disorders with ineffective hematopoiesis, which are incurable with conventional therapy. Of note, MDS features an abnormal bone marrow microenvironment, which is related to its incidence. The hypoxia­inducible factor­1α (HIF­1α) transcriptional signature is generally activated in bone marrow stem/progenitor cells of patients with MDS. To analyze the expression of HIF­1α in bone marrow mesenchymal stem cells (BM­MSCs) and the apoptosis and cell cycle features associated with the disease, BM­MSCs were obtained from 40 patients with a definitive diagnosis of MDS and 20 subjects with hemocytopenia but a negative diagnosis of MDS as a control group. Reverse transcription­quantitative PCR and western blot analyses were used to measure HIF­1α expression in cells from the two groups and apoptosis and cell cycle were also analyzed and compared between the groups using flow cytometry assays. BM­MSCs from both the control group and the MDS group exhibited a fibroblast­like morphology, had similar growth cycles and were difficult to passage stably. It was observed that BM­MSCs from the MDS group had significantly higher HIF­1α expression levels than the control group (P<0.05). Furthermore, the BM­MSCs from the MDS group had a higher proportion of cells in early apoptosis (5.22±1.34 vs. 2.04±0.08%; P<0.0001) and late apoptosis (3.38±0.43 vs. 1.23±0.11%; P<0.01) and exhibited cell cycle arrest. This may be a noteworthy aspect of the pathogenesis of MDS and may be related to high HIF­1α expression under a hypoxic state in the bone marrow microenvironment. Furthermore, the expression of HIF­1α in bone marrow tissue sections from patients with MDS in the International Prognostic Scoring System (IPSS) lower­risk group was higher than that from patients with MDS in the IPSS high­risk group. These results revealed the role of HIF­1α as a central pathobiology mediator of MDS and an effective therapeutic target for a broad spectrum of patients with MDS, particularly for patients in the lower­risk group.

MicroRNA-124 suppresses the invasion and proliferation of breast cancer cells by targeting TFAP4.

MicroRNA (miRNA/miR)-124 is widely accepted as the suppressor of different tumors. The present study aimed to improve understanding of the potential role of miR-124 in breast cancer. The gene expression profile change derived from the overexpression of miR-124 was investigated using RNA sequencing and bioinformatics analysis of the breast cancer cell line SKBR3. The results demonstrated that the gene expression profile of SKBR3 cells significantly changed. In addition, the transcription factor activating enhancer-binding protein 4 (TFAP4) gene was identified among the top 10 differentially expressed genes, and was identified as a novel target gene of miR-124 using a dual-luciferase reporter assay. TFAP4 knockdown in notably impaired SKBR3 cell migration and proliferation, which was consistent with decreasing migration and proliferation ability following overexpression of miR-124. Taken together, these results suggest that overexpression of miR-124 can suppress the migration and proliferation of SKBR3 cells by tarsgeting TFAP4. Thus, TFAP4 may act as a novel therapeutic target of breast cancer.

Fenretinide attenuates lipopolysaccharide (LPS)-induced blood-brain barrier (BBB) and depressive-like behavior in mice by targeting Nrf-2 signaling.

The transcription factor nuclear factor erythroid-2 related factor 2 (Nrf2) is a dominant manager to inhibit oxidative and inflammatory damage. Fenretinide (Fen) is a novel agent, showing significant role in regulating oxidative stress and inflammatory response. However, its effects on lipopolysaccharide (LPS)-induced brain injury are still unclear. In the present study, we explored the regulatory role of Fen in LPS-triggered neuroinflammation, and the underlying molecular mechanisms. Results here indicated that Fen treatment markedly improved Nrf2 expression and nuclear translocation in mouse brain endothelial cell line bEnd.3 cells, and promoted Nrf2-antioxidant responsive element (ARE) transcription activity, as well as its down-streaming signals, which was Nrf2-dependent. Fen also exhibited cytoprotective role in LPS-stimulated bEnd.3 cells through improving anti-oxidant capacity and inhibiting inflammation by the blockage of nuclear factor-kappa B (NF-κB) signaling. Mouse model with brain injury induced by LPS, Fen administration markedly attenuated the behavior impairments, blood-brain-barrier (BBB) and the histological changes in hippocampus samples. Additionally, Fen attenuated oxidative stress and blunted inflammation in hippocampus of LPS-challenged mice. Therefore, results in the study highlighted the protective role of Fen against LPS-elicited brain injury.

MiR-342-3p inhibition promotes cell proliferation and invasion by directly targeting ID4 in pre-eclampsia.

AIM: This study aimed to explore the miR-342-3p expression in pre-eclampsia (PE) placentas and confirm whether miR-342-3p exerts effects on proliferation and migration of HTR-8/SVneo trophoblastic cells. METHODS: The PE placentas (n = 8) were taken from gravidas complicated by PE and delivered after 34 weeks. The chorionic plates and the basal plates were separately taken from the placenta disc near the position of umbilical cord insertion. RT-qPCR was used to measure the expression of miR-342-3p in the chorionic plates and the basal plates. Cell invasion assay and MMT assay were used to assess the effects of miR-342-3p on proliferation and migration of HTR-8/SVneo trophoblastic cells. Luciferase reporter assay and Western blotting were used to analyze the target of miR-342-3p and investigate the detailed mechanisms. RESULTS: The expression of miR-342-3p was upregulated in both basal plates and chorionic plates in patients with PE compared with healthy pregnant individuals. MiR-342-3p inhibitor suppressed the cell viability and invasion, and induced apoptosis in trophoblast cells. Furthermore, inhibitor of DNA binding (ID)-4 (ID4) was a direct target of miR-342-3p, and knockdown of ID4 abrogated the regulation effect of miR-342-3p on cell viability, apoptosis and invasion. CONCLUSION: Inhibition of miR-342-3p expression may suppress the occurrence of PE by targeting ID4 in vitro.

IL-8 -251A/T and +781C/T polymorphisms were associated with risk of breast cancer in a Chinese population.

Breast cancer is the leading cause of death of women in worldwide. The real mechanism of breast cancer is still unclear. IL-8 is a member of the chemokine superfamily, which plays an important role in regulating both inflammatory and immune processes. We performed a hospital-based case-control study to estimate the association between IL-8 -251A/T, -353A/T and +781C/T polymorphisms and risk of breast cancer in a Chinese population, and interaction between IL-8 polymorphism and environmental factors. During January 2014 and July 2016, a total of 442 patients with breast cancer and 447 normal control subjects were enrolled into our study. The IL-8 -251A/T, -353A/T and +781C/T polymorphisms were analyzed by the polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP). The TT genotype of IL-8 -251A/T was associated with higher risk of breast cancer as compared with the AA genotype (adjusted OR=1.96, 95% CI=1.26-3.05). Individuals carrying TT genotype of IL-8 -251A/T was correlated with an elevated risk of breast cancer in recessive model, when compared with the AA+AT genotype (adjusted OR=1.91, 95% CI=1.26-2.90). For the IL-8 +781C/T, the TT genotype showed lower association with risk of breast cancer in comparison to the CC genotype (adjusted OR=0.49, 95% CI=0.26-0.91); the TT genotype was also correlated with a decreased risk of breast cancer in recessive model (adjusted OR=0.46, 95% CI=0.25-0.84), as compared with the CC+CT genotype. In conclusion, our study suggests that IL-8 -251A/T and +781C/T could potentially be a biomarker for susceptibility to breast cancer risk.

Structure-based design of peptides against HER2 with cytotoxicity on colon cancer.

In this study, we found that four novel peptides designed by molecular modeling techniques were successfully applicated with cytotoxicity on colon cancer cells sw620. First, the interactions between the Herstatin and the HER2 were explored by ational-designed approaches, which were combined with homology modeling, protein/protein docking, and structural superimposition analysis. Then, based on the results derived from theoretical analysis, four novel peptides were designed, synthesized, and experimentally evaluated for biological function; it was found that they showed a remarkable enhancement on Herceptin to inhibit the genesis and development of colon cancers, and no significant side effects on normal colon cells NCM460 were observed but Doxorubicin had. These results indicated that it is a feasible way to use the well-designed peptides derived from Herstatin to enhance the efficacy of clinical drugs Herceptin and to kill colon cancer cells selectively without harming normal colon cells. We believe that our research might provide a new way to develop the potential therapies for colon cancers.

Effect of individualized diabetes education for type 2 diabetes mellitus: a single-center randomized clinical trial.

BACKGROUND: To evaluate the effect of individualized education for patients with type 2 diabetes mellitus (T2DM). METHODS: A total of 280 patients (158 males, mean age 63 ± 10 years) with T2DM were randomly divided into study and control group. Eysenck Personality questionnaire was used to assess the personality of the patients in the study group, which was provided us one-on-one counseling and individualized management plan. Group education was provided to the control group. RESULTS: At the end of the study, the body mass index (21.5±2.5 vs 23.6±1.6 kg/m2, P =0.002), waist circumference (83.7±6.4 vs 85.7±7.7 cm, P =0.03), fasting blood glucose (6.0±0.8 vs 6.9±2.1 mmol/L, P =0.004), HbA1c (6.2±0.6% vs 6.9±3.1%, P =0.03), systolic blood pressure (130.1±8.8 vs 135.1±8.4 mmHg, P =0.003),triglyceride (1.21±0.66 vs 1.46±0.58 mmol/L) and low-density lipoprotein (2.36±0.44 vs 2.84±0.64 mmol/L, P =0.03) in the study group was lower than in the control group. CONCLUSION: Individualized diabetes education is more effective than group education in facilitating the control of type 2 diabetes.

Family structure and quality of life of elders in rural China: the role of the new rural social pension.

Using data from a survey in Ankang district of Shaanxi province of China in 2011, this article examines the protective effect of the New Rural Social Pension (NRSP) on quality of life of rural elders, as well the moderating effect on association between family structure and quality of life. An instrumental variable approach is used. NRSP is shown to significantly improve the quality of life of rural elders, and a robustness check shows that this effect is consistent across different sets of subgroups. Compared with the elders who have at least one son, the quality of life of those who are childless or have only one child is significantly lower. The NRSP is more likely to significantly improve the quality of life of one-child elders. In addition, the associations between the NRSP and the different facets of quality of life of the elders are significant except for the facet of sensory abilities.

Association mapping of seed oil and protein content in Sesamum indicum L. using SSR markers.

Sesame is an important oil crop for the high oil content and quality. The seed oil and protein contents are two important traits in sesame. To identify the molecular markers associated with the seed oil and protein contents in sesame, we systematically performed the association mapping among 369 worldwide germplasm accessions under 5 environments using 112 polymorphic SSR markers. The general linear model (GLM) was applied with the criteria of logP ≥ 3.0 and high stability under all 5 environments. Among the 369 sesame accessions, the oil content ranged from 27.89%-58.73% and the protein content ranged from 16.72%-27.79%. A significant negative correlation of the oil content with the protein content was found in the population. A total of 19 markers for oil content were detected with a R2 value range from 4% to 29%; 24 markers for protein content were detected with a R2 value range from 3% to 29%, of which 19 markers were associated with both traits. Moreover, partial markers were confirmed using mixed linear model (MLM) method, which suggested that the oil and protein contents are controlled mostly by major genes. Allele effect analysis showed that the allele associated with high oil content was always associated with low protein content, and vice versa. Of the 19 markers associated with oil content, 17 presented near the locations of the plant lipid pathway genes and 2 were located just next to a fatty acid elongation gene and a gene encoding Stearoyl-ACP Desaturase, respectively. The findings provided a valuable foundation for oil synthesis gene identification and molecular marker assistant selection (MAS) breeding in sesame.

Identification and testing of reference genes for Sesame gene expression analysis by quantitative real-time PCR.

Sesame (Sesamum indicum L.) is an ancient and important oilseed crop. However, few sesame reference genes have been selected for quantitative real-time PCR until now. Screening and validating reference genes is a requisite for gene expression normalization in sesame functional genomics research. In this study, ten candidate reference genes, i.e., SiACT, SiUBQ6, SiTUB, Si18S rRNA, SiEF1α, SiCYP, SiHistone, SiDNAJ, SiAPT and SiGAPDH, were chosen and examined systematically in 32 sesame samples. Three qRT-PCR analysis methods, i.e., geNorm, NormFinder and BestKeeper, were evaluated systematically. Results indicated that all ten candidate reference genes could be used as reference genes in sesame. SiUBQ6 and SiAPT were the optimal reference genes for sesame plant development; SiTUB was suitable for sesame vegetative tissue development, SiDNAJ for pathogen treatment, SiHistone for abiotic stress, SiUBQ6 for bud development and SiACT for seed germination. As for hormone treatment and seed development, SiHistone, SiCYP, SiDNAJ or SiUBQ6, as well as SiACT, SiDNAJ, SiTUB or SiAPT, could be used as reference gene, respectively. To illustrate the suitability of these reference genes, we analyzed the expression variation of three functional sesame genes of SiSS, SiLEA and SiGH in different organs using the optimal qRT-PCR system for the first time. The stability levels of optimal and worst reference genes screened for seed development, anther sterility and plant development were validated in the qRT-PCR normalization. Our results provided a reference gene application guideline for sesame gene expression characterization using qRT-PCR system.

[Clinical significance of serum NGF level and CD271 expression in patients with acute B lymphoid leukemia].

The aim of this study was to detect the nerve growth factor (NGF) level in serum and NGF low affinity acceptor CD271 expression on bone marrow leukemic cells in acute B lymphoid leukemia (B-ALL) patients and to analyze their clinical significance. The NGF level in serum and CD271 expression on leukemic cells in bone marrow were detected by enzyme linked immunosorbent assay and flow cytometry in B-ALL patients respectively. The results indicated that compared with control group, the NGF level in serum of patient group significantly increased (t = 4.191, p < 0.05), but CD271 expression on leukemic cells in bone marrow decreased significantly (t = 4.898, p < 0.05). The complete remission (CR) rate of 25 B-ALL patients was 64% (16/25) after one course of CVAD chemotherapy. There were statistically significant differences of NGF level and CD271 expression in non-remission (NR) group and control group (t = 3.976, p < 0.05 vs t = 5.052, p < 0.05), but there were no statistically difference of NGF level and CD271 expression in CR group (t = 1.102, p > 0.05 vs t = 1.150, p > 0.05) as compared with control group. The CD271 expression before and after chemotherapy between CR and NR groups showed statistically significant differences (t = 3.889, p < 0.05; t = 3.751, p < 0.05 and t = 4.678, p < 0.05 respectively), but NGF level before and after chemotherapy showed no statistical difference between these 2 groups (t = 0.476, p > 0.05). 50% (8/16) patients relapsed during following up, and of their NGF level [(168.00 ± 61.66) pg/ml] and CD271 expression [(52.29 ± 13.00)%] showed the significantly differences, compared with those in control group (t = 5.284, p < 0.05 vs. t = 6.073, p < 0.05), but the NGF level [(81.13 ± 25.32) pg/ml] and CD271 expression [(78.45 ± 7.12)%] of other 8 patients showed no statistical difference as compared with control group (t = 1.228, p > 0.05 vs t = 1.144, p > 0.05). Compared with low NGF level and CD271 low expression groups, the survival time of B-ALL patients with high NGF level and CD271 expression was not changed significantly (p = 0.750 vs p = 0.170). It is concluded that the increased NGF level in serum and decreased CD271 expression on bone marrow leukemic cells in B-ALL patients are related with leukemia development and may be the useful indexes to evaluate curative effect and prognosis.

[Clinical significance of tissue factor and vascular endothelial growth factor expressions on CD14+ monocytes in patients with non Hodgkin lymphoma].

OBJECTIVE: To explore the values of tissue factor (TF) and vascular endothelial growth factor (VEGF) expressions on peripheral CD14+ monocytes in disease assessment, prognosis, and short-term efficacy evaluation of non-Hodgkin lymphoma (NHL) patients. METHODS: TF and VEGF expressions on CD14+monocytes in 47 NHL patients (disease group) before chemotherapy and after 4 chemotherapy cycles and in 30 healthy subjects (control group) were detected by flow cytometry, and the potential relationship among TF, VEGF, International Prognostic Index (IPI), and short-term efficacy were analyzed. RESULTS: TF and VEGF expressions on CD14 + monocytes in disease group were significantly higher than those in control group ( all P <0. 01) and positive correlation was showed between them (r = 0. 708, P = 0.00). TF and VEGF expressions in Ann Arbor stage III and IV (n = 22 and 19) , symptomatic (n = 22) , lactate dehydrogenase (LDH) increased (n = 21) , Eastern Cooperative Oncology Group (ECOG) score 2-4 (n = 12) and extranodal lesions >1 (n = 16) groups were significantly higher than those in Ann Arbor stage II (an = 6) , asymptomatic (an =25) , LDH normal (n = 26) , ECOG score 0-1 ( n = 35) and extranodal lesions ~1 ( na = 31) groups, respectively (all P <0.05). The expressions of TF and VEGF on CD14 + monocytes in high-risk (n = 7) or high-middle-risk (n = 11) groups were significantly increased compared with low-risk (n = 15) or low-middle-risk(n = 14) groups, respectively (all P <0. 01). TF and VEGF expressions in non-remission group before chemotherapy (n = 11) were both obviously higher than those in remission group (an = 36, all P <0. 01) , and after chemotherapy their expressions in remission group were significantly lower than those before chemotherapy (all P <0. 01) , while such significant changes were not observed in the non-remission group ( all P > 0. 05). CONCLUSION: The high expressions of TF and VEGF on peripheral CD14 + monocytes can be useful markers in dis-ease assessment, prognosis evaluation and short-term efficacy observation of NHL patients.

[Relationship between coagulation function and international prognostic index in lymphoma patients].

The study was aimed to investigate the clinical significance of coagulation function changes in lymphoma patients and to analyze the relationship between their changes and international prognostic index (IPI). The prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB) were detected by magnetic bead method in 75 lymphoma patients and 20 healthy persons. The dehydrogenase (LDH) level was detected by rate method in all lymphoma patients and healthy persons. The results showed that (1) the APTT and FIB more obviously increased in lymphoma patients which displayed as hyperfibrinogenemia, as compared with control group (p < 0.05, p < 0.01); no obvious changes of coagulation indexes presented in patients with different ages and extranodal lesions (p > 0.05, p < 0.01). (2) APTT and FIB levels in stage III and IV patients were much higher than those in the stage II (p < 0.05 and < 0.01), and FIB level in stage IV group was significantly higher than those in the stage III (p < 0.05). FIB level in symptomatic group was significantly higher than that in asymptomatic group (p < 0.01). (3) APTT and FIB in increased LDH group were obviously higher than those in control group (p < 0.05, p < 0.01). Furthermore, FIB in increased LDH group was higher than that in normal LDH group (p < 0.05). FIB in performance status (PS) 2 - 4 groups increased significantly as compared with those in PS 0-1 group (p < 0.01). (4)FIB levels in the low-middle-risk, high-middle-risk and high-risk groups were significantly higher than those in control group (p < 0.01), while FIB levels in high-middle-risk and high-risk groups were higher than those in low-risk group (p < 0.05). (5) the number of FIB increased patients in symptomatic group, increased LDH group, PS 2 - 4 group and Ann Arbor stage III-IV group were much higher than those in counterparts (p < 0.05 or 0.01).There were positive correlations between FIB and LDH level, PS grades, Ann Arbor stages as well as risk grades respectively (p < 0.05 or 0.01). It is concluded that lymphoma patients usually accompany with hyperfibrinogenemia which may be influenced by Ann Arbor stage, systemic symptom, LDH level and PS grade. FIB is supposed to be an effective indication of prognosis in lymphoma patients.

[Treatment of acute radiation pneumonia with Qingfei Huatan Quyu method].

OBJECTIVE: To observe the therapeutic effect of Qingfei Huatan Quyu method (QHQ, a Chinese medicinal therapy for clearing Fei-heat and dissolving phlegm-stasis) combined with hormone-antibiotic therapy (HAT) on radiation pneumonia (RP). METHODS: Eighty-one patients with RP were randomized into two groups, 41 patients in the control group and 40 in the treatment group were treated with HAT alone and HAT combined with QHQ respectively for 21 days. The severity of RP was evaluated before and after treatment according to the criteria of the radiation therapy oncology group. The effect on TCM symptoms and chest roentgenogram, as well as on plasma levels of interleukin-6 ( IL-6) and transform growth factor-beta (TGF-beta) were detected. RESULTS: After treatment, number of patients with RP graded as 0, 1, 2, 3, and 4 in the treatment group was 23, 10, 4, 2, and 1, respectively, while in the control group, 14, 9, 11, 4, and 3, respectively. The combined therapy showed effects in improving RP grading (P <0.01) and TCM syndromes were superior to those of HAT respectively (P < 0.05). Besides, levels of IL-6 and TGF-beta were lowered after treatment in the treatment group, showing a significant difference to those in the control group (P <0.05). CONCLUSION: QHQ combined with HAT has a definite therapeutic effect on RP. It could efficiently decrease the plasma levels of IL-6 and TGF-beta in patients with RP.
