Network pharmacology analysis and experimental validation of Xiao-Qing-Long-Tang's therapeutic effects against neutrophilic asthma.

BACKGROUND: Xiao-Qing-Long-Tang (XQLT), a classical Chinese herbal medicine formula, has been extensively used for allergic asthma treatment. However, there is limited research on its anti-inflammatory effects and mechanisms specifically in neutrophilic asthma (NA). PURPOSE: This study aims to investigate the potential therapeutic effects of XQLT against NA using a combination of network pharmacology and experimental validation. STUDY DESIGN: By utilizing traditional Chinese medicine and disease databases, we constructed an XQLT-asthma network to identify potential targets of XQLT for NA. In the experimental phase, we utilized an ovalbumin (OVA)/lipopolysaccharide (LPS)-induced model for neutrophilic asthma and examined the therapeutic effects of XQLT. RESULTS: Our research identified 174 bioactive components within XQLT and obtained 140 target genes of XQLT against asthma. Functional enrichment analysis revealed that these target genes were primarily associated with inflammation and cytokines. In the experimental validation, mice induced with OVA-LPS showcased eosinophilic and neutrophilic cell infiltration in peri-bronchial areas, elevated levels of IL-4 and IL-17 in both serum and lung, increased percentages of Th2 and Th17 cells in the spleen, as well as elevated levels of CD11b+ and CD103+ dendritic cells (DCs) within the lung. Treatment with XQLT effectively reduced IL-4 and IL-17 levels, decreased the percentages of Th2, Th17, CD11b+, and CD103+ DCs, and improved inflammatory cell infiltrations in lung tissues. These findings serve as a foundation for the potential clinical application of XQLT in neutrophilic asthma.

Huangqi Decoction, a compound Chinese herbal medicine, inhibits the proliferation and activation of hepatic stellate cells by regulating the long noncoding RNA-C18orf26-1/microRNA-663a/transforming growth factor-β axis / 中西医结合学报

OBJECTIVE@#Huangqi Decoction (HQD), a classical traditional Chinese medicine formula, has been used as a valid treatment for alleviating liver fibrosis; however, the underlying molecular mechanism is still unknown. Although our previous studies showed that microRNA-663a (miR-663a) suppresses the proliferation and activation of hepatic stellate cells (HSCs) and the transforming growth factor-β/small mothers against decapentaplegic (TGF-β/Smad) pathway, whether long noncoding RNAs (lncRNAs) are involved in HSC activation via the miR-663a/TGF-β/Smad signaling pathway has not yet reported. The present study aimed to investigate the roles of lncRNA lnc-C18orf26-1 in the activation of HSCs and the mechanism by which HQD inhibits hepatic fibrosis.@*METHODS@#The expression levels of lnc-C18orf26-1, miR-663a and related genes were measured by quantitative reverse transcription-polymerase chain reaction. HSCs were transfected with the miR-663a mimic or inhibitor and lnc-C18orf26-1 small interfering RNAs. The water-soluble tetrazolium salt-1 assay was used to assess the proliferation rate of HSCs. Changes in lncRNA expression were evaluated in miR-663a-overexpressing HSCs by using microarray to identify miR-663a-regulated lncRNAs. RNA hybrid was used to predict the potential miR-663a binding sites on lncRNAs. Luciferase reporter assays further confirmed the interaction between miR-663a and the lncRNA. The expression levels of collagen α-2(I) chain (COL1A2), α-smooth muscle actin (α-SMA) and TGF-β/Smad signaling pathway-related proteins were determined using Western blotting.@*RESULTS@#Lnc-C18orf26-1 was upregulated in TGF-β1-activated HSCs and competitively bound to miR-663a. Knockdown of lnc-C18orf26-1 inhibited HSC proliferation and activation, downregulated TGF-β1-stimulated α-SMA and COL1A2 expression, and inhibited the TGF-β1/Smad signaling pathway. HQD suppressed the proliferation and activation of HSCs. HQD increased miR-663a expression and decreased lnc-C18orf26-1 expression in HSCs. Further studies showed that HQD inhibited the expression of COL1A2, α-SMA, TGF-β1, TGF-β type I receptor (TGF-βRI) and phosphorylated Smad2 (p-Smad2) in HSCs, and these effects were reversed by miR-663a inhibitor treatment.@*CONCLUSION@#Our study identified lnc-C18orf26-1 and miR-663a as promising therapeutic targets for hepatic fibrosis. HQD inhibits HSC proliferation and activation at least partially by regulating the lnc-C18orf26-1/miR-663a/TGF-β1/TGF-βRI/p-Smad2 axis.

Traditional Chinese Medicine Intervention in Membranous Nephropathy Based on Podocyte Injury： A Review / 中国实验方剂学杂志

Membranous nephropathy， an autoimmune kidney disease with glomerular podocyte injury as the core mechanism， is a common pathological type of adult nephrotic syndrome and has become the main cause of end-stage renal disease in China. Podocytes are terminally differentiated cells that play an important role in maintaining the structural and functional stability of glomeruli and are molecular barriers for protein filtration. Glomerular filtration membrane injury induced by podocyte injury is an important cause of massive proteinuria. Persistent or aggravated proteinuria may prolong the course of membranous nephropathy. It is believed that podocyte destruction in membranous nephropathy is mainly related to oxidative stress， autophagy dysregulation， abnormal expression of podocyte marker proteins， chronic inflammation， epithelial-mesenchymal cell transdifferentiation， and so on. At present， western medicine mostly uses immunosuppressants and hormones for treatment according to its pathological stage， but there are certain adverse reactions. Traditional Chinese medicine （TCM） has made some achievements in the prevention and treatment of membranous nephropathy. In recent years， studies have found that many Chinese medicines can affect the occurrence and development of membranous nephropathy in different links by acting on multiple targets in the human body， with manifest advantages. This paper overviewed the podocyte injury mechanism in membranous nephropathy and summarized the treatment of membranous nephropathy with Chinese medicine monomers， compounds， and Chinese patent medicines in intervening related target pathways， aiming to provide a basis for the clinical treatment， basic research， and targeted drug development of TCM against membranous nephropathy.

Clinical efficacy of sticking-needle acupuncture plus tendon-regulating manipulation in the treatment of acute ankle sprain / 针灸推拿医学（英文版）

Objective: To explore the treatment effect of sticking-needle acupuncture plus tendon-regulating manipulation on pain, swelling and joint dysfunction due to acute ankle sprain.Methods: A total of 80 patients with acute ankle sprain were recruited and divided into a control group and a treatment group according to the random number table method, with 40 patients in each group. Both groups received the same conventional interventions. The control group was treated with additional tendon-regulating manipulation, and the treatment group was treated with tendon-regulating manipulation plus sticking-needle acupuncture. The pain, swelling and joint dysfunction of the ankle were observed in both groups before and after 3 d, 7 d and 14 d of treatment. Results: Before treatment, there was no statistically significant difference in the visual analog scale (VAS) score of pain between the two groups (P>0.05). After treatment, the VAS scores of both groups showed a decreasing trend over time, and the differences within the groups were statistically significant (P<0.05). After 3 d, 7 d and 14 d of treatment, the VAS scores in the treatment group were lower than those in the control group, with statistically significant differences (P<0.05). Before treatment, there was no statistically significant difference in the degree of swelling between the two groups (P>0.05). After treatment, the degrees of swelling in both groups showed a decreasing trend over time, and the differences within the groups were statistically significant (P<0.05). After 3 d and 7 d of treatment, the degrees of swelling in the treatment group were lower than those in the control group, with statistically significant differences (P<0.05). There was no statistical difference in the degree of swelling between the two groups after 14 d of treatment (P>0.05). Before treatment, there was no statistically significant difference in the American Orthopedic Foot Ankle Society (AOFAS) ankle-hindfoot scale score between the two groups (P>0.05). After treatment, the AOFAS ankle-hindfoot scale scores of both groups showed an increasing trend over time, and all the differences within the groups were statistically significant (P<0.05). After 3 d, 7 d and 14 d of treatment, the AOFAS ankle-hindfoot scale scores in the treatment group were higher than those in the control group, with statistically significant differences (P<0.05). Conclusion: Based on the routine intervention, the addition of sticking-needle acupuncture and tendon-regulating manipulation was better in alleviating pain and swelling and improving joint function in patients with acute ankle sprain than the addition of tendon-regulating manipulation alone.

[Effects of electroacupuncture on miR-34a-5p/SIRT1 signaling in the trigeminal ganglion of rats with migraine].

OBJECTIVE: To investigate the effect of electroacupuncture(EA) on miR-34a-5p, silent mating type information regulation 2 homolog-1 (SIRT1) and nuclear factor-κB subunit p65 (NF-κB p65) in the trigeminal ganglion of rats with migraine, so as to explore the mechanisms of EA underlying prevention of migraine. METHODS: Male SD rats were randomly divi-ded into normal, sham operation, model, EA, and EA plus EX527(a SIRT1 inhibitor) groups, with 10 rats in each group. The rat model of migraine was established by electrical stimulation of the trigeminal ganglion. Before modeling, EA was applied at "Waiguan"(TE5) and "Fengchi"(GB20) for 20 min each time, once a day for 5 consecutive days, and intraperitoneal injection of EX527 (5 mg/kg) every day simultaneously. Serum prostaglandin E2 (PGE2) and calcitonin gene-related peptide (CGRP) concentrations were measured by enzyme-linked immunosorbent assay. The levels of miR-34a-5p, SIRT1 and interleukin-1ß (IL-1ß) mRNA，and protein expression of SIRT1, IL-1ß, NF-κB p65, NF-κB Ac-p65 and cyclooxygenase-2 （COX2） in trigeminal ganglia were detected by real-time quantitative PCR and Western blot, separately. RESULTS: The serum concentrations of PGE2 and CGRP， the expression of miR-34a-5p, IL-1ß mRNA and protein, NF-κB p65, NF-κB Ac-p65 and COX2 protein expression in the trigeminal ganglion were remarkably increased (P<0.05), while the SIRT1 mRNA and protein decreased (P<0.05) in the model group in contrast to the normal group. Following EA intervention， the serum PGE2 and CGRP concentrations, miR-34a-5p expression, IL-1ß mRNA and protein, NF-κB p65, NF-κB Ac-p65 and COX2 protein expression were significantly down-regulated (P<0.05), and SIRT1 mRNA and protein significantly up-regulated (P<0.05). Compared with the EA group, the serum concentrations of PGE2 and CGRP, IL-1ß mRNA and protein, NF-κB p65, NF-κB Ac-p65 and COX2 protein expressions increased (P<0.05), and SIRT1 protein decreased (P<0.05) in the EA plus EX527 group. CONCLUSION: In migraine rats, EA can inhibit miR-34a-5p expression in the trigeminal ganglion, increase SIRT1 expression, down-regulate IL-1ß/COX2 inflammation signals, reduce PGE2 synthesis, and thus redue CGRP released from the peripheral terminals, which may be one of the mechanisms of EA in preventing migraine.

[Effect of electroacupunture on supplementary analgesia and the levels of serum ß-endorphin and prostaglandin E2 in patients with total knee arthroplasty].

OBJECTIVE: To observe the effect on supplementary analgesia after total knee arthroplasty (TKA) treated with electroacupunture, and explore it's mechanism. METHODS: A total of 40 patients with severe knee osteoarthritis were randomized into an observation group and a control group, 20 cases in each one. During the operation, patients were given epidural anesthesia in the two groups, conventional patient controlled epidural analgesia and oral celecoxib were applied after the operation. In the observation group, electroacupunture was used at Liangqiu (ST 34), Xuehai (SP 10), Yinlingquan (SP 9), Zusanli (ST 36), Fenglong (ST 40) and Qiuxu (GB 40) on the operation side from the 1st to 7th day after the operation to support analgesia, 30 min for each time, once a day. The visual analogue scale (VAS) was used to record postoperative pain of resting state and active state. The levels of serum prostaglandin E2 and ß-endorphin were measured on the 1st and 7th day after surgery in the two groups. RESULTS: In the observation group, the VAS scores of resting state and active state were superior to the control group on the 3rd, 5th and 7th day after the operaton (all P<0.05); after the treatment, the level of serum ß-endorphin was increased and the level of serum prostaglandin E2 was reduced in the two groups (all P<0.05), and the change of the observation group was larger than that of the control group (both P<0.05). CONCLUSION: Electroacupunture has the effect of supplementary analgesia for patients after TKA, the mechanism may be related to promote the synthesis of ß-endorphin and inhibit the synthesis of prostaglandin E2.

[Electroacupuncture Intervention Reduces Post-surgical Pain of Patients Undergoing Total Knee Arthroplasty].

OBJECTIVE: To observe the analgesic effect and safety of electroacupuncture (EA) intervention for patients undergoing total knee arthroplasty (TKA). METHODS: A total of 40 patients undergoing TKA were randomly assigned to control group (simple multi-mode analgesia, n＝20) and EA group (EA combined with multi-mode analgesia, n＝20). Both groups were treated with epidural anesthesia during surgical operation, and conventional epidural automatic analgesia and oral Celecoxib after surgery. Following surgery, EA was applied to Liangqiu (ST 34)-Xuehai (SP 10), Yinlingquan (SP 9)-Zusanli (ST 36), Fenglong (ST 40)-Qiuxu(GB 40) on the operation side for 30 min, once daily for 7 consecutive days. The patients' pain state during rest and motion was assessed by using visual analogue scale (VAS). The active and passive knee flexion range of motion (ROM), use of painkillers including the number of patient's controlled epidural analgesia (PCEA) during 48 h after surgery, and other complications were recorded. RESULTS: After the treatment, the VAS scores under rest and motion state were both significantly lower in the EA group than in the control group on day 3, 5 and 7 after surgery (P<0.05). During 48 h after surgery, the number of PECA was significantly lower in the EA group than in the control group (P<0.05). Of the two 20 cases in the control and EA groups, 3 and 1 asked to receive muscular injection of Tramadol Hydrochloride for pain relief, 3 and 2 experienced nausea-vomiting, 2 and 1 had dizziness and headache, and 2 and 1 had a chest distress feeling, respectively, which had no significant differences between the two groups (P>0.05). The white blood cell (WBC) count in both groups were decreased gradually from day 1 to 7 after surgery, and plasma C-reactive protein content on day 5 and 7 were also lowered in both groups, without statistical differences between the two groups in the post-operative complications, dosages of additional postoperative analgesic drugs, and levels of plasma WBC and C-reactive protein (P>0.05). CONCLUSION: EA can effectively improve the early postoperative pain of TKA, reduce the incidence of postoperative complications and the use of analgesic drugs in TKA patients.

Modified Suanzaorentang Had the Treatment Effect for Generalized Anxiety Disorder for the First 4 Weeks of Paroxetine Medication: A Pragmatic Randomized Controlled Study.

Background. Paroxetine does not show satisfactory therapeutic effect for generalized anxiety disorder (GAD) patients for the first 2-4 weeks of medication. Diazepam is always concurrently used although it has some shortcomings such as physical dependence and withdrawal reactions. In this study, we aimed to identify whether modified Suanzaorentang (MSZRT), a combined Chinese formula including Suanzaorentang (SZRT) and Zhizichitang (ZZCT), could control the anxiety of GAD for the first 4 weeks of paroxetine medication. Methods. 156 GAD patients were randomized to the treatment of paroxetine, paroxetine-diazepam, or paroxetine-MSZRT for 4 weeks. Hamilton Anxiety Scale (HAMA) Test and Self-Rating Anxiety Scale (SAS) Test were determined each week as the evaluation of clinical efficacy. Adverse events (AEs) were also closely observed by performing the Treatment Emergent Symptom Scale (TESS) Test. Results. Both paroxetine-MSZRT and paroxetine-diazepam decreased more HAMA and SAS total scores than paroxetine from weeks 1 to 3. Paroxetine-MSZRT as well as paroxetine-diazepam had an obviously higher onset rate than paroxetine in each week. After 4 weeks' treatment, the overall effectiveness rate in the paroxetine-MSZRT group (90.00%) was obviously higher than those of the paroxetine group (74.42%) but did not significantly differ from the paroxetine-diazepam group (93.88%). Conclusion. MSZRT had the treatment effect for GAD when paroxetine was used for the first 4 weeks.

Sinomenine prevents metastasis of human osteosarcoma cells via S phase arrest and suppression of tumor-related neovascularization and osteolysis through the CXCR4-STAT3 pathway.

Osteosarcoma is the most common primary malignant tumor of the bone. The long-term survivals continue to be unsatisfactory for patients with metastatic and recurrent disease. Metastasis is still a severe challenge in osteosarcoma treatment. Sinomenine, an alkaloid from traditional Chinese medicine, has been proved to possess potent antitumor and anti-invasion effect on various cancers. However, the effect of sinomenine on human osteosarcoma and the underlying mechanisms remains unknown. We report here that sinomenine inhibited proliferation by inducing S phase arrest and suppressing the clone formation. Significant inhibitory effects were found in invasion and metastasis in osteosarcoma, but little cytotoxicity was observed in tested concentrations. Exposure to sinomenine resulted in suppression of invasion and migration in osteosarcoma cells as well as tube formation ability in the human umbilical vein endothelial cells (HUVEC) and U2OS cells. Furthermore, it demonstrated that CXCR4 played a key role contributing to invasion in osteosarcoma which is considered to be a core target site in sinomenine treatment. Sinomenine inhibited invasion by suppressing CXCR4 and STAT3 phosphorylation then downregulating the expression of MMP-2, MMP-9, RANKL, VEGF downstream. In addition, then RANKL-mediated bone destruction stimulated by osteoclastogenesis and VEGF-related neovascularization were restrained. Importantly, in vivo, sinomenine suppressed proliferation, osteoclastogenesis and bone destruction. Through these various comprehensive means, sinomenine inhibits metastasis in osteosarcoma. Taken together, our results revealed that sinomenine caused S phase arrest, inhibited invasion and metastasis via suppressing the CXCR4-STAT3 pathway and then osteoclastogenesis-mediated bone destruction and neovascularization in osteosarcoma. Sinomenine is therefore a promising adjuvant agent for metastasis control in osteosarcoma.

[Effect of acupuncture on early onset of SSRIs treating depressive disorder and related indicators of neuroimmunology].

OBJECTIVE: To observe the intervention effect of acupuncture on early onset of selec- tive serotonin reuptake inhibitors (SSRIs) in treating depressive disorder, and to study its effect on ser- um 5-HT and unbalanced inflammatory cytokines secreted by TH1/TH2. METHODS: Totally 90 patients with depressive disorder were randomly assigned to the drug control group (as the control group, 45 cases) and the acupuncture combined drug treatment group (as the treatment group, 45 cases). All patients were treated for 4 consecutive weeks. Another 45 healthy subjects were recruited as a healthy control group. The effect of acupuncture on early onset of SSRls in treating acute phase depressive disorder pa- tients was evaluated by HAMD score in the control group and the treatment group before treatment,and at weekends of the 1st, 2nd, and 4th week after treatment. Besides, their serum levels of 5-HT, IL-1ß and IL-6 (secreted by TH1), and IL-4 and IL-10 (secreted by TH2) were detected before treatment and after treatment at the weekend of the 4th week. RESULTS: Compared with the healthy control group,serum lev- els of 5-HT, IL-4, and IL-10 decreased in the two drug-treated groups before treatment (P < 0.01); serum levels of IL-1ß and IL-6 increased (P <0.01). Compared with before treatment in the same group, HAMD score decreased in the control group at weekends of the 2nd and the 4th week after treatment (P < 0.01); HAMD scores decreased in the treatment group at weekends of the 1st, 2nd, 3rd,and 4th week after treatment (P < 0.01); serum levels of 5-HT, IL-4, and IL-10 increased,serum levels of IL-1ß and IL- 6 decreased in the two drug-treated groups after treatment (all P < 0.01).

Developmental status and prospect of musical electroacupuncture / 中国针灸

Through searching domestic and foreign medical journals in CNKI, Wanfang database, VIP database and Pubmed database from January of 2003 to November of 2013, 39 articles regarding musical electroacupuncture (MEA) were analyzed. The result showed that MEA was clinically used to treat neurological and psychotic disorders; because it was combined with musical therapy and overcame the acupuncture tolerability, and MEA was superior to traditional electroacupuncture. However, problems such as low research efficiency and the mechanism of MEA superiority and the musical specificity not being revealed by research design still exist. In future, large-sample multi-center RCT researches should be performed to clarify MEA clinical efficacy. With modern science and technology and optimized study design, guided by five-element theory of TCM, researches on different musical elements and characteristics of musical pulse current as well as MEA's correlation with meridians and organs should be studied, so as to make a further exploration on MEA mechanisms and broaden the range of its clinical application.

Efficient method for analyzing absorbed ingredients of traditional Chinese medicine genitana macrophyllae radix / 中国中药杂志

In present study, a method for analyzing the absorbed ingredients of traditional Chinese medicine QinJiao has been developed. A rat everted gut sac (EGS) model has been established, and the transporting capacity of gut sacs was identified by histological examinations. The ingredients including loganic acid, sweroside, gentiopicroside, and swertiamarian in serosal solution absorbed by active transport of rat everted ileum and jejunum from Qinjiao extraction were determined using an HPLC method. Histological integrality of the gut sacs remains perfect and the active transport activity of them is normal within 45 min of the experiment. The HPLC method employed in this study presents high specificity and good correlation. The relative standard deviation of precision of this method is less than 5.5%. Extraction recovery of samples is more than 90%. And stability of the samples in room temperature is perfect. Eight ingredients of Qinjiao absorbed in serosal solution are identified. Furthermore, concentration of Qinjiao extraction significantly affects accumulated absorption and absorption coefficient of the ingredients. However, there is no significant impact on the accumulated absorption and absorption coefficient by diverse of everted gut sections. From above, the EGS techniques might be an efficient method, which can be employed for investigation of absorbed ingredients of Traditional Chinese Medicines.

PURPOSE: Patients undergoing a total thyroidectomy plus neck dissection are at high risk of developing postoperative hypocalcemia. This study prospectively evaluated the possibility to identify factors that predict symptomatic hypocalcemia and the necessity of routine calcium supplements. METHODS: Sixty-five consecutive patients who underwent a total thyroidectomy plus neck dissection were included. Intact parathyroid hormone (iPTH), total serum calcium (sCa), serum phosphate (sPhos), and serum magnesium (sMg) levels were monitored and compared between the symptomatic hypocalcemic group ( group A) and the asymptomatic hypocalcemic group (group B). RESULTS: Asymptomatic and self-limiting hypocalcemia developed in 54 patients (81.5%; group B). Symptomatic hypocalcemia developed in 11 patients (18.5%; group A). They required calcium supplements. There were no significant differences in the iPTH and sMg levels between the two groups; the sCa level was significantly lower on postoperative days 1, 2, 3, and 5 in group A than in group B (P < 0.05); the sPhos level was significantly higher on postoperative days 2 and 3 in group A than in group B (P < 0.05). CONCLUSIONS: Symptomatic hypocalcemia develops within 3 days after surgery. An sCa level of less than 1.81 mmol/l can predict symptomatic hypocalcemia. Routine calcium supplements will not be necessary if the sCa level is higher than 1.81 mmol/l.

Protective effect of panaxatriol saponins extracted from Panax notoginseng against MPTP-induced neurotoxicity in vivo.

AIM OF THE STUDY: Panaxatriol saponins (PTS), the main constituents extracted from Panax notoginseng, a Chinese herbal medicine, has been shown to be an effective agent on various diseases. Our previous study has demonstrated that PTS is an inducer of thioredoxin-1 (Trx-1) and has a possible potential as a therapeutic agent for Parkinson's disease (PD). However, the effect of PTS on 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced neurotoxicity in vivo is unknown. MATERIALS AND METHODS: Using locomotor activity test and traction test, we detected the effect of PTS on MPTP-induced behavioral impairment. Tyrosine hydroxylase, Trx-1, cyclooxygenase-2, pro-caspase-9, pro-caspase-12 and caspase-3 expressions in the anatomical region of substantia nigra pars compacta (SNc) were tested by Western blot. RESULTS: PTS provided neuroprotection against the loss of dopaminergic neurons and behavioral impairment caused by MPTP. MPTP-induced neuronal death in the SNc was suppressed by PTS through increasing Trx-1 expression, suppressing cyclooxygenase-2 over-expression and inhibiting mitochondria-mediated apoptosis. CONCLUSIONS: PTS, an inducer of Trx-1, has pluripharmacological properties in the protection against PD including enhancing antioxidant activity, acting as neurotrophic factor, modulating inflammation and inhibiting mitochondria-mediated apoptosis.

Panaxatriol saponins extracted from Panax notoginseng induces thioredoxin-1 and prevents 1-methyl-4-phenylpyridinium ion-induced neurotoxicity.

AIM OF THE STUDY: Thioredoxin-1 has various biologic activities, including the control of redox balance and the inhibition of apoptosis. The current study was designed to examine the effects of panaxatriol saponins (PTS) extracted from Panax notoginseng on thioredoxin-1 expression and 1-methyl-4-phenylpyridinium ion-induced injury. MATERIALS AND METHODS: Using PC12 cells and Kunming mice, we test thioredoxin-1 expression after PTS treatment by Western blot. The protective effect of PTS against 1-methyl-4-phenylpyridinium ion-induced injury was assessed by MTT assay and LDH release assay. RESULTS: PTS induced thioredoxin-1 expression in vitro and in vivo, and attenuated 1-methyl-4-phenylpyridinium ion-induced cell death of PC12 cells. CONCLUSIONS: PTS is a new inducer of thioredoxin-1 and has a possible potential as a therapeutic agent for neurodegenerative diseases including Parkinson's disease.

Effects of traditional Chinese medicine on the differentiation of mesenchymal stem cells to osteoblasts / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To investigate the effects of traditional Chinese medicine on the differentiation of mesenchymal stem cells (MSC) to osteoblasts.</p><p><b>METHODS</b>Six male Beagle dogs weighed 10-15 kg each were divided into three groups, group A: medicine serum group, group B: non-medicine serum group and group C: bovine serum group. The serum of group A was obtained from the femoral artery of 2 Beagle dogs drinking equivalent dose of traditional Chinese medicine according to body surface area for 7 continuous days. The serum of group B was collected from the femoral artery of 2 Beagle dogs fed with equal volume of normal saline for 7 days. The serum of group C was fetal bovine serum. The tibia marrow was harvested from another 2 Beagle dogs and MSC were isolated and purified by density gradient centrifugation. MSC were cultured in DMEM solution with fetal bovine serum. After MSC were digested by trypsin, MSC were cultured in DMEM solution with the osteogeneic inducer, which contained dexamethasone, antiscorbutic and beta-glycerophosphate. Morphological and histological changes of the MSC were observed under an inverted microscope. Alizarin monosulfonate and nitric acid argentum staining was performed to observe the calcium deposition. MSC were curtured in DMED solution with medicine serum (group A), non-medicine serum (group B) and bovine serum (group C) respectively. The growth curve was detected by the methyl thiazolyl tetrazolium (MTT). The alkaline phosphatase (ALP) activities were detected to observe the differentiation of MSC.</p><p><b>RESULTS</b>The original MSC were observed as fibroblast-like cell shapes. After the osteogeneic inducer was added, MSC were polygon cells with a few polyprocess. Calcium deposition appeared during 10-14 days and alizarin monosulfonate and Von Kossa staining presented positive. MTT results showed that the number of adherent cells of group A was more than that of group B and that of group C significantly after 6 days (P < 0.05). ALP detection proved that ALP activity of group A was more than that of group B and that of group C significantly after 5 days (P < 0.05).</p><p><b>CONCLUSIONS</b>The traditional Chinese medicine promotes the differentiation of MSC to osteoblasts and osteogenesis.</p>
