ABSTRACT

OBJECTIVE@#To explore the effects of prognostic nutritional index (PNI) combined with D-dimer on the prognosis of patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL).@*METHODS@#The clinical data of 73 DLBCL patients at initial diagnosis were retrospectively evaluated, and the optimal cut-off point of PNI and D-dimer were determined by ROC curve. The overall survival (OS) rate and progression-free survival (PFS) rate in different subgroups were compared using Kaplan-Meier survival curves. Univariate and multivariate Cox regression analysis was performed to identify the factors associated with OS.@*RESULTS@#Compared with the low PNI group (PNI<44.775), the high PNI group (PNI≥44.775) had better OS (P =0.022) and PFS (P =0.029), the 2-year OS rates of the two groups were 55.6% and 78.3% respectively (P =0.041). Compared with the high D-dimer group (D-dimer≥0.835), the low D-dimer group (D-dimer<0.835) had better OS (P <0.001) and PFS (P <0.001), the 2-year OS rates of the two groups were 51.4% and 86.8% respectively (P =0.001). Meanwhile, patients in the high PNI+ low D-dimer group had better OS (P =0.003) and PFS (P <0.001) than the other three groups, the 2-year OS rate was statistically different from the other three groups (P <0.05). The multivariate analysis revealed that NCCN-IPI (HR =2.083, 95%CI : 1.034-4.196, P =0.040), PNI (HR =0.267, 95%CI : 0.076-0.940, P =0.040) and PNI+D-dimer (HR =9.082, 95%CI : 1.329-62.079, P =0.024) were the independent risk factors affecting OS in patients with DLBCL. Subgroup analysis showed that PNI, D-dimer, and PNI combined with D-dimer could improve the prognostic stratification in low and low-intermediate risk DLBCL patients.@*CONCLUSION@#High PNI, low D-dimer and combination of high PNI and low D-dimer at initial diagnosis suggest a better prognosis in DLBCL patients.

ABSTRACT

Previously, we discovered that cells contain a 5-hydroxytryptamine (5-HT) degradation system (5DS), which includes 5-HT2A receptor (5-HT2AR), 5-HT synthase, and monoamine oxidase A (MAO-A). Among these, 5-HT2AR has the ability to regulate the expression of 5-HT synthase and MAO-A, and activation of 5DS causes upregulation of these proteins at the same time, resulting in the production of reactive oxygen species (ROS) in the mitochondria. In this study, we investigated the relationship between interstitial pneumonia (IP) and 5DS activation, as well as the therapeutic effect of inhibiting 5DS on IP. Animal models of bleomycin (BLM)-induced IP in mice and radiation (Rad)-induced IP in rats were established, and the models were treated with the 5-HT2AR antagonist sarpogrelate hydrochloride (SH), 5-HT synthesis inhibitor carbidopa (CDP), and their combination (SH∶CDP = 2∶1). The animal experiments were carried out in accordance with the regulations of the Animal Ethics Committee of China Pharmaceutical University. In the two IP models, immunohistochemistry staining and Western blot analysis showed that the expression of 5-HT synthase was significantly upregulated in all cells of lung tissue, while the expression of 5-HT2AR and MAO-A was most significantly upregulated in the macrophages. Treatment with SH or CDP significantly reduced pulmonary interstitial thickening, alveolar atrophy with collapse, massive macrophage infiltration and interstitial fibrosis in the two IP models, as measured by HE and Masson staining, and a combination of both almost eliminated the lung tissue lesions. Moreover, treatment with the combination of SH and CDP almost completely eliminated increased ROS and malondialdehyde levels, decreased superoxide dismutase activity, increased tumor necrosis factor-α and interleukin-1β levels, and upregulated nuclear factor-κB phosphorylation and α‍-smooth muscle actin, matrix metalloproteinase-2, and collagen expression. SH and CDP worked together to create a synergistic effect. The findings suggested that the activation of 5DS, as evidenced by increased 5-HT synthesis in all cells of lung tissue and increased 5-HT synthesis and degradation in macrophages, is probably related to the occurrence of IP and that inhibition of 5DS can effectively treat IP.

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy of initial periodontal therapy in periodontitis patients with or without type 2 diabetes mellitus and its correlation with white blood cell counts.@*METHODS@#In this study, 32 chronic periodontitis patients without systemic disease (CP group) and 27 chronic periodontitis patients with type 2 diabetes mellitus (CP+DM group) were enrolled. At admission, all the patients went through periodontal examination and fasting blood examination(baseline). Probing depth (PD), attachment loss (AL), bleeding index (BI), plaque index (PLI), white blood cells (WBC) counts and fasting blood glucose (FBG) were recorded respectively, while hemoglobin A1c (HbA1c) was recorded only in CP+DM group. After that, initial periodontal therapy was performed. All the tests were repeated 3 and 6 months after treatment. The changes of periodontal clinical indexes and WBC levels were compared between the two groups before and after treatment, and the correlation between WBC and periodontal clinical indexes and glucose metabolism indexes were analyzed by generalized linear mixed model.@*RESULTS@#At baseline, the periodontal inflammation and destruction were similar in CP and CP+DM group, but the WBC level was significantly higher in CP+DM groups [(6.01±1.26)×109/L vs. (7.14±1.99)×109/L, P=0.01]. After 3 and 6 months of initial periodontal therapy, the mean PD, AL, BI, and PLI in CP+DM and CP groups were significantly lower than the baseline, and the PD in CP+DM group was further decreased by 6 months compared with 3 months [(3.33±0.62) mm vs. (3.61±0.60) mm, P < 0.05]. However, none of these periodontal indexes showed significant difference between the two groups by 3 or 6 months. In CP+DM group, HbA1c at 3 months and 6 months were significantly lower than the baseline [(7.09±0.79)% vs. (7.64±1.16)%, P < 0.05; (7.06±0.78)% vs. (7.64±1.16)%, P < 0.05], and FBG was significantly lower than the baseline by 6 months [(7.35±1.14) mmol/L vs. (8.40±1.43) mmol/L, P < 0.05]. The WBC level in CP group was significantly lower than the baseline level by 3 months [(5.35±1.37)×109/L vs. (6.01±1.26)×109/L, P < 0.05], while that in CP+DM group was significantly lower than the baseline level by 6 months [(6.00±1.37)×109/L vs. (7.14±1.99)×109/L, P < 0.05]. The analysis of genera-lized linear mixed model showed that WBC level was significantly positively correlated with PD and FBG (P < 0.05).@*CONCLUSION@#Initial periodontal therapy can effectively improve the periodontal clinical status of patients with or without type 2 diabetes mellitus, and have benefits on glycemic control in diabetic patients. However, the response of periodontal indexes and WBC level to initial therapy were relatively delayed in diabetic patients. WBC plays an important role in the correlation between diabetes mellitus and periodontitis.

ABSTRACT

ObjectiveTo explore the effect of Danggui Niantongtang (DGNTT) on cell apoptosis and autophagy in rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLS). MethodRA-FLS were isolated and cultured from the synovial tissue of RA patients. The cells were treated with 10% blank serum (blank control group), 10% sera containing low, medium and high doses of DGNTT. Wound healing assa and cell invasion test were applied to observe the effect of RA-FLS invasion technique. The apoptosis and autophagy level of RA-FLS cells was detected by Hoechst33342 method and monodansylcadaverine (MDC) staining. The mRNA and protein expression levels of B cell lymphoma-2 (Bcl-2), Bcl-2 associated X protein (Bax), microtubule-associated protein 1 light chain 3 (LC3), autophagy key molecular yeast Atg6 homolog 1 (Beclin1) were detected by Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR)and Western blot. ResultCompared with the blank control group,each dose of serum could slow down the wound healing and significantly Reduce the number of RA-FLS cells invading the lower chamber(P<0.01),the mRNA and protein expression levels of Bcl-2,LC3,Beclin1 were significantly decreased(P<0.01), and Bax were significantly increased(P<0.01). Hoechst33342 results showed that low, medium and high doses DGNTT could promote RA-FLS cell apoptosis. After MDC staining,autophagosome in low, medium and high doses DGNTT decreased significantly(P<0.01). ConclusionDanggui Niantongtang can effectively inhibit the proliferation of fibroblast-like synoviocytes. Its mechanism may be related to promote apoptosis and inhibit autophagy of fibroblast-like synoviocytes.

ABSTRACT

ObjectiveTo observe the preventive and control effects of Danggui Niantongtang against adjuvant arthritis differentiated into wind-damp-heat impediment in rats and its influences on the expression of autophagy-related proteins microtubule-associated protein 1 light chain 3 (LC3), homolog of yeast Atg6 (Beclin1) and p62. MethodThe six-week-old male SD rats were randomly divided into the normal group, wind-damp-heat impediment model group, low-, medium-, and high-dose Danggui Niantongtang (5.67, 11.34, 22.68 g·kg-1) groups, and methotrexate (MTX, 1.35 mg·kg-1) group, with 10 rats in each group. A rat model of adjuvant arthritis was established by subcutaneous injection of inactivated Mycobacterium tuberculosis into the tail root, followed by exposure to the manual climatic box for 16 d for inducing the wind-damp-heat impediment. The drugs were administered intragastrically on the day of immunization for 28 d. The general conditions of rats were observed and the swelling degree of toes and arthritis index (AI) were detected. The pathological changes in the synovial tissues of the knee joints were observed by hematoxylin-eosin (HE) staining. The mRNA expression levels of LC3, Beclin1, and p62 in the synovial tissues were measured by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), followed by the assay of their protein expression by Western blot and immunohistochemistry. ResultCompared with the normal group, the wind-damp-heat impediment model group exhibited significantly increased swelling degree of toes (P<0.01), increased AI (P<0.01), proliferated synovial cells (P<0.01), up-regulated LC3 and Beclin1 protein and mRNA expression (P<0.01), and down-regulated p62 protein and mRNA expression (P<0.01) after 16, 20, 24, 28-d medication. Compared with the wind-damp-heat impediment model group, each medication group displayed alleviated toe swelling and synovial hyperplasia to different degrees, decreased mRNA and protein expression levels of LC3 and Beclin1 (P<0.01), and increased p62 mRNA and protein expression (P<0.05,P<0.01), with the best outcomes observed in the medium-dose Danggui Niantongtang group. ConclusionDanggui Niantongtang effectively relieves adjuvant arthritis due to wind-damp-heat impediment in rats, which may be related to its regulation of the expression of autophagy-related proteins LC3, Beclin1, and p62 and the inhibition of autophagy.

ABSTRACT

Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a rare adverse cutaneous reaction with a low incidence and high mortality. Despite posing a serious threat to patients' health and lives, there is no high-quality evidence for a standard treatment regimen. Here we report the case of a 62-year-old man with stage IV pancreatic cancer who experienced immunotherapy-induced SJS/TEN. After consensus-based regular treatments at a local hospital, his symptoms became worse. Thus, he consented to receive Chinese herbal medicine (CHM) therapy. The affected parts of the patient were treated with the CHM Pi-Yan-Ning which was applied externally for 20 min twice a day. After 7 days of treatment, the dead skin began peeling away from the former lesions that had covered his hands, feet, and lips, indicating that skin had regenerated. After 12 days of treatment, the patient's skin was completely recovered. In this case, SJS/TEN was successfully treated with Pi-Yan-Ning, suggesting that there might be tremendous potential for the use of Pi-Yan-Ning in the treatment of severe skin reactions to drug treatments. Further basic investigations and clinical trials to explore the mechanism and efficacy are needed.

ABSTRACT

Fatigue is a common complication of type 2 diabetes mellitus (T2DM). We examined the relationship between T2DM fatigue and the skeletal muscle 5-hydroxytryptamine (5-HT) system. In animal experiments, a T2DM model was established in mice by feeding a high-fat diet with intraperitoneal injection of streptozotocin. The mice were treated with the 5-HT2A receptor antagonist sarpogrelate hydrochloride (SH) and the 5-HT synthesis inhibitor carbidopa (CDP) (separately and in combination). In cell culture experiments, C2C12 cells were stimulated with D-glucose, palmitic acid or 5-HT. 5-HT2AR, 5-HT synthesis and 5-HT degradation were inhibited by SH, CDP, or monoamine oxidase A (MAO-A) inhibitor. The animal experiments were in accordance with the regulations of the Animal Ethics Committee of China Pharmaceutical University. The results showed that 5-HT2AR, 5-HT synthase and MAO-A were expressed in mouse skeletal muscle and C2C12 cells. The expression of these proteins was significantly up-regulated in T2DM mice or when C2C12 cells were exposed to palmitic acid and D-glucose; palmitic acid was a stronger stimulant of their expression than D-glucose. Rotating rod experiments and biochemical index tests have shown that T2DM fatigue is associated with an increase in skeletal muscle 5-HT2AR, 5-HT synthesis and 5-HT degradation. 5-HT2AR mediates the expression of MAO-A and the synthesis of 5-HT, which indirectly regulates the degradation of 5-HT. MAO-A regulates cell inflammation, mitochondrial ROS production and membrane potential depolarization by mediating 5-HT degradation. MAO-A also inhibits the expression of peroxisome proliferator-activated receptor γ coactivator-1 (PGC-1), carnitine palmitoyltransferase-1 (CPT1) and ATP synthase-6 (ATP6), thus inhibiting mitochondrial functions such as fatty acid β oxidation and ATP synthesis. SH and CDP can effectively treat T2DM fatigue, and can also reduce blood glucose and blood lipid, and the combination of SH and CDP has a clear synergistic effect.

ABSTRACT

Pneumoconiosis, an interstitial lung disease that occurs from breathing in certain kinds of damaging dust particles, is a major occupational disease in China. Patients diagnosed with occupational pneumoconiosis can avail of free medical treatment, whereas patients without a diagnosis of occupational diseases cannot not claim free medical treatment in most provinces from the government before 2019. This study aimed to analyze the priority of medical facility selection and its influencing factors among patients with pneumoconiosis. A total of 1,037 patients with pneumoconiosis from nine provinces in China were investigated. The health service institutions most frequently selected by the patients were county-level hospitals (37.5%). The main reason for the choice was these hospitals' close distance to the patients' homes (47.3%). The factors for the choice of health care institutions were living in the eastern region (

ABSTRACT

Objective:To observe the effect of Danggui Niantongtang on the protein and mRNA expression of key regulatory factors of the extrinsic and intrinsic apoptotic pathway in synovial tissue of adjuvant arthritis (AA) rats, and to further explore the mechanism of Danggui Niantongtang in the prevention and treatment of rheumatoid arthritis. Method:The general condition of AA rats, including its body weight, were observed. The changes of toe volume were detected by toe volume meter. Histopathological changes of synovium of knee joint were observed by hematoxylin-eosin (HE) staining. The mRNA and protein expression levels of tumor necrosis factor receptor super family 6 (Fas), Fas-associating protein with a novel death domain(FADD), B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax) and cysteinyl aspartate specific proteinase Caspase-3 (Caspase-3) were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot. Result:Compared with the normal group, the toe volume of the model group increased significantly (<italic>P</italic><0.01), with significantly proliferated synovial cells, significantly reduced mRNA and protein expression levels of Fas, FADD, Bax and Caspase-3 in synovial tissues(<italic>P</italic><0.05,<italic> P</italic><0.01), and significantly increased Bcl-2 level (<italic>P</italic><0.01). Compared with the model group, the swelling degree of toes in Danggui Niantongtang group and Tripterygium group was significantly alleviated (<italic>P</italic><0.01), with significantly improved synovial hyperplasia, significantly increased mRNA and protein expression levels of Fas, FADD, Bax and Caspase-3 (<italic>P</italic><0.05, <italic>P</italic><0.01), and significantly decreased expression levels of bcl-2 mRNA and protein (<italic>P</italic><0.05, <italic>P</italic><0.01). Conclusion:Danggui Niantongtang can effectively reduce joint swelling and abnormal proliferation of synovial tissue in AA rats. Its mechanism may be related to regulating the expression of Fas, FADD, Bax, Bcl-2 and Caspase-3, and promoting the apoptosis of synovial cells.

ABSTRACT

Hyperglycemic kidney injury (HKI) is a common complication of diabetic patients. We examined the relationship between HKI and the abnormal expression of 5-hydroxytryptamine (5-HT) system induced by hyperglycemia in type 2 diabetes mellitus (T2DM). In animal experiments, a T2DM model was established in mice by feeding a high-fat diet with intraperitoneal injection of streptozotocin. The mice were treated with the 5-HT2A receptor (5-HT2AR) antagonist sarpogrelate hydrochloride (SH) and 5-HT synthesis inhibitor carbidopa (CDP) (respectively or in combination). In cell culture experiments, human glomerular mesangial cells (HMC) were stimulated with D-glucose (D-Glu), and 5-HT2AR, 5-HT synthesis, and 5-HT degradation were inhibited by SH, CDP, or monoamine oxidase A (MAO-A) inhibitor clorgyline. Periodic acid-Schiff (PAS) staining and Masson staining, immunohistochemistry and Western blot, fluorescent probe, and enzyme linked immunosorbent assay (ELISA) and enzyme reagent were respectively used to detect histopathology, protein expression, intracellular reactive oxygen species (ROS), and biochemical indexes. The animal experiments were in accordance with the regulations of the Animal Ethics Committee of China Pharmaceutical University. The results showed that 5-HT2AR, 5-HT synthases, and MAO-A were expressed in glomerular basement membrane and kidney tubular epithelial cells of mouse kidney and HMC. The expression of these proteins was significantly up-regulated in T2DM mice or when HMC cells were exposed to high concentration of D-Glu. HKI, characterized by abnormal renal function, glomerular swelling, and glomerular basement membrane thickening and fibrosis, is closely associated with an increase in kidney 5-HT2AR, 5-HT synthesis, and 5-HT degradation. Among them, 5-HT2AR can mediate the expression of 5-HT synthases and MAO-A; MAO-A can catalyze the degradation of 5-HT to increase the production of mitochondrial ROS, leading to the phosphorylation of nuclear factor kappa B (NF-κB) with the production of inflammatory cytokines, and the up-regulation of matrix metalloproteinase-2 (MMP-2) and α-smooth muscle actin (α-SMA) with the production of collagens. SH and CDP can effectively treat HKI, and the combination of SH and CDP has a clear synergistic effect.

ABSTRACT

Background: Human infections with zoonotic coronaviruses (CoVs), including severe acute respiratory syndrome (SARS)-CoV and Middle East respiratory syndrome (MERS)-CoV, have raised great public health concern globally. Here, we report a novel bat-origin CoV causing severe and fatal pneumonia in humans. Methods: We collected clinical data and bronchoalveolar lavage (BAL) specimens from five patients with severe pneumonia from Jin Yin-tan Hospital, Wuhan, Hubei province, China. Nucleic acids of the BAL were extracted and subjected to next-generation sequencing. Virus isolation was carried out, and maximum-likelihood phylogenetic trees were constructed. Results: Five patients hospitalized from December 18 to December 29, 2019 presented with fever, cough, and dyspnea accompanied by complications of acute respiratory distress syndrome. Chest radiography revealed diffuse opacities and consolidation. One of these patients died. Sequence results revealed the presence of a previously unknown β-CoV strain in all five patients, with 99.8–99.9% nucleotide identities among the isolates. These isolates showed 79.0% nucleotide identity with the sequence of SARS-CoV (GenBank NC_004718) and 51.8% identity with the sequence of MERS-CoV (GenBank NC_019843). The virus is phylogenetically closest to a bat SARS-like CoV (SL-ZC45, GenBank MG772933) with 87.6–87.7% nucleotide identity, but is in a separate clade. Moreover, these viruses have a single intact open reading frame gene 8, as a further indicator of bat-origin CoVs. However, the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV, indicating that these viruses might use the same receptor. Conclusion: A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans.

ABSTRACT

Objective@# The short-term clinical effects of two kinds of normal temperature flow root sealers (the calcium silicate-based sealer iRoot SP and the siloxane-based sealer GuttaFlow2) combined with single point filling technology and a frequently-used sealing agent (AH Plus) combined with continuous wave hot tooth filling technology were evaluated. @*Methods @#A total of 279 teeth (656 root canals) were randomly divided into three groups: the iRoot SP group, GuttaFlow2 group and AH plus group. We recorded the filling time of each root canal, collected a digital dental film to evaluate the filling effect of each root canal, and conducted a follow-up visit one week and one month after the operation to record the incidence of pain. We used SPSS 18.0 to analyze the above data. @*Results @# There was no significant difference in the root canal filling effect among the three groups (P > 0.05). There was no significant difference in the filling time between the iRoot SP group and the GuttaFlow2 group (P > 0.05), but the filling time was significantly shorter in the AH Plus group (P < 0.05). There was no significant difference in the postoperative pain between the iRoot SP group and the GuttaFlow2 group (P > 0.05), and the incidence of pain in the iRoot SP group and the GuttaFlow2 group was lower than that in the AH Plus group (P < 0.05).@*Conclusions @# GuttaFlow2 and iRoot SP combined with single point filling technology can save filling time and obtain good clinical effects compared with frequently-used hot tooth filling technology and the incidence of postoperative pain was low.

ABSTRACT

BACKGROUND@#Hemorrhoids are one of the most common conditions that lead to surgery, and until now surgical hemorrhoidectomy has been the major effective treatment. Post-operative pain from hemorrhoidectomy has been experienced by thousands of patients and remains a major inconvenience of the operation.@*OBJECTIVE@#This study evaluates the clinical efficacy of the pestle needle therapy, an acupoint stimulation method, for relief of post-hemorrhoidectomy pain.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS@#This was a single-center, patient-assessor-blinded and randomized controlled trial with 154 patients receiving Milligan hemorrhoidectomy surgery. Eligible patients were randomly assigned to either a treatment group or a control group at a ratio of 1:1. The treatment group received the pestle needle therapy, with manual stimulation at Yaoshu (DU2), Mingmen (DU4), Changqiang (DU1), Chengshan (BL57), Erbai (EX-UE2) and the perianal points (1, 3, 5, 7, 9, and 11o'clock around the lesion); while the control group received a sham treatment with very light pressure. Three sessions of treatment were performed at 30 min, 4 h and 12 h after the surgery, and each lasted for 15 min.@*MAIN OUTCOME MEASURES@#The primary outcome was post-operative pain measured with the visual analogue scale (VAS) at 12 h after surgery. The secondary outcomes included the VAS scores measured at 0.5, 2, 4, 6, 8, 24 and 48 h after surgery, the analgesic dose, the time and the VAS score of the patients' first defecation after surgery, as well as the Hamilton Rating Scale for Anxiety (HAMA) evaluated before discharge.@*RESULTS@#The mean pain score of the treatment group was significantly lower than that of the control group (3.10 ± 1.27 vs 4.82 ± 1.29; P < 0.001) at 12 h after surgery. Compared with the control group, patients in the treatment group needed a smaller dose of analgesic within the first 24 hours after surgery (P = 0.002); and their HAMA scores before discharge were lower (4.07 ± 2.40 vs 5.10 ± 2.45, P = 0.009). Compared to the treatment group, patients in the control group had a greater time to the first defecation after surgery ([52.34 ± 15.72] h vs [27.08 ± 13.68] h; P < 0.001), but there was no difference in their VAS scores at the first defecation (P = 0.092).@*CONCLUSION@#The pestle needle therapy was effective for relieving pain, reducing anxiety and improving bowel function after hemorrhoidectomy, and it is worthy of clinical application.

ABSTRACT

It is crucial to establish a complete set of traditional Chinese medicine(TCM) quality traceability management process system, in order to stabilize the pricing order of TCM market and reconstruct the transmission path of TCM quality signals. In this study, we reviewed the mature experience of food and drug supervision at home and abroad, analyzed the quality characteristics of TCM, and put forward that the quality control of TCM products can learn from the hazard analysis and critical control point(HACCP) system in food safety quality control. This study points out that the HACCP system provides not only technical guidance for the traceability management of TCM, but also ideas for improving the quality of TCM products and the safety risk control of TCM. The application of the HACCP system in TCM quality control can help establish an international dialogue platform for TCM and help realize the modernization and internationalization of TCM industry.

ABSTRACT

Dao-di herbs have been synonymous with quality medicinal herbs in our mind hearts since ancient times and are the essence of Chinese medicine culture. The development of genuine regional herbs faces problems such as insufficient supply of local resources and lack of competitive advantages. It is necessary to seek a suitable model to protect and develop authentic medicinal materials. The protection mode of geographical indication products has become more mature. Geographical indication(GI) products and authentic medicinal materials are all related to the origin. There is certain commonality between them. However, there are also differences between authentic Chinese herbal medicines and geographical indications, and it is unsuitable to simply equate the authentic Chinese medicinal materials with GI products. This article comprehensively combs and compares the development of the authentic Chinese herbal medicines and geographical indication products, and believes that it is necessary to fully learn from the experience of GI products and combine the characteristics of authentic medicinal materials to establish a set of protection systems that meet the characteristics of authentic medicinal materials. Through this research, it has positive significance to promote the protection and management of authentic medicinal materials.

ABSTRACT

OBJECTIVE@#To evaluate the association between Chinese medicine (CM) therapy and disease-free survival (DFS) outcomes in postoperative patients with non-small cell lung cancer (NSCLC).@*METHODS@#This multiple-center prospective cohort study was conducted in 13 medical centers in China. Patients with stage I, II, or IIIA NSCLC who had undergone radical resection and received conventional postoperative treatment according to the National Comprehensive Cancer Network (NCCN) guidelines were recruited. The recruited patients were divided into a CM treatment group and a control group according to their wishes. Patients in the CM treatment group received continuous CM therapy for more than 6 months or until disease progression. Patients in the control group received CM therapy for less than 1 month. Follow-up was conducted over 3 years. The primary outcome was DFS, with recurrence/metastasis rates as a secondary outcome.@*RESULTS@#Between May 2013 and August 2016, 503 patients were enrolled into the cohort; 266 were classified in the CM treatment group and 237 in the control group. Adjusting for covariates, high exposure to CM was associated with better DFS [hazard ratio (HR) = 0.417, 95% confidential interval (CI): 0.307-0.567)]. A longer duration of CM therapy (6-12 months, 12-18 months, >24 months) was associated with lower recurrence and metastasis rates (HR = 0.225, 0.119 and 0.083, respectively). In a subgroup exploratory analysis, CM therapy was also a protective factor of cancer recurrence and metastasis in both stage I-IIIA (HR=0.50, 95% CI: 0.37-0.67) and stage IIIA NSCLC postoperative patients (HR = 0.48, 95% CI: 0.33-0.71), DFS was even longer among CM treatment group patients.@*CONCLUSIONS@#Longer duration of CM therapy could be considered a protective factor of cancer recurrence and metastasis. CM treatment is associated with improving survival outcomes of postoperative NSCLC patients in China. (Registration No. ChiCTR-OOC-14005398).
