Effects of mesenchymal stem cells on Treg cells in rats with colitis.

The aim was to investigate the therapeutic effect of bone marrow mesenchymal stem cells (BM-MSC) on dextran sulfate sodium (DSS) induced colitis in rats and its effect on regulatory T cells (Treg). A model of DSS-induced colitis was established. BM-MSC was isolated and cultured to observe the efficacy of BM-MSC on colitis, including general vital signs, weight changes, colonic length changes, colonic histopathological changes, and colonic tissue MPO activity. The expression of inflammatory factors (IFN-γ, IL-4, IL-17, TGF-ß) in colonic tissues was measured by real-time PCR. The amount of CD4 + CD25 + Treg was detected by flow cytometry. Real-time PCR was used to detect Foxp3+mRNA in CD4 + CD25 + Treg, western to detect Foxp3+protein expression in CD4 + CD25 + Treg, and ELISA was used to detect IL-35 and IL-10 cytokines in CD4 + CD25 + Treg culture supernatant. Results show that intravenous injection of BM-MSC significantly improved the clinical manifestations and histopathological changes in rats with experimental DSS colitis; significantly down-regulated the expression of inflammatory factors IFN-γ, IL-4, and IL-17 and up-regulated the expression of TGF-ß in colon tissues; BM-MSC also increased the number of CD4+CD25+Foxp3+Treg and enhanced the function of CD4+CD25+Foxp3+Treg in colon tissues, and up-regulated the expression of IL-35. In conclusion, BM-MSC has a certain therapeutic effect on DSS-induced colitis. It can improve the general signs of colitis rats and reduce intestinal injury and inflammatory response. The immunoregulatory effect of BM-MSC is achieved by enhancing the function of CD4+CD25+Foxp3+Treg and up-regulating the secretion of immunosuppressive inflammatory factors.

[Professor SHAO Jing-ming's clinical experience of fire needling for surgical diseases].

Professor SHAO Jing-ming's clinical experience of fire needling for bone-joint tuberculosis, tuberculous cervical lymphadenitis, ganglion cyst and thyrophyma is summarized. Professor SHAO used fire needling to treat bone-joint tuberculosis. The acupoints included ashi points and nearby acupoints, particularly local opposite acupoints (Neixiyan [EX-LE 4] and Dubi [ST 35], Yinlingquan [SP 9] and Yanglingquan [GB 34], Xuehai [SP 10] and Liangqiu [ST 34]), and for the patients with severe yin-cold syndrome, Yanghe decoction was additionally used. For tuberculous cervical lymphadenitis, fire needling was used at different stages. In the early stage, the nucleus was punctured with fire needling; in the middle stage, the pustule was punctured with fire needling combined with cupping; in the late stage, the fire needling was inserted into the fistula or sinus tract, and the surrounding granulation tissue was treated with horizontal penetrating needling. For ganglion cyst, fire needling combined with centro-square needling was applied. For thyrophyma, the surrounding needling with filiform was used; for simple thyroid mass and thyroid nodule, the surrounding needling with fire needling was used.

A Retrospective Analysis of Clinical Features and Treatment of the Inflammatory Bowel Disease in China.

Purpose: To retrospectively collect and analyze demographic information as well as symptoms, laboratory results, endoscopic and pathologic findings, and treatment of ulcerative colitis (UC) and Crohn's disease (CD) patients in Wuhan, China. Methods: Patients who were diagnosed as inflammatory bowel disease (IBD) and hospitalized from January 2012 to December 2017 were enrolled in this study. The clinical characteristics including symptoms, laboratory results, and treatment were reviewed and analyzed. Results: Totally 821 cases were screened, and finally 430 UC patients and 286 CD patients were selected and enrolled in this study. The most common symptom in UC patients was bloody stool (90.7%) followed by diarrhea (87.7%), mucus in stool (72.1%), and abdominal pain (66.3%), which were significantly different from those of CD patients (P < 0.01). In contrast, the most common symptom in CD patients was abdominal pain (80.0%) followed by diarrhea (58.4%), bloody stool (27.6%), and fever (18.2%). Erythrocyte sedimentation, C-reactive protein, and platelets were significantly increased, while hemoglobin was decreased, in the moderately or highly active IBD. The percentage of positive perinuclear anti-neutrophil cytoplasmic antibody was significantly higher in UC patients (31.1%) than that in CD patients (4.8%, P < 0.001), while the percentage of positive anti-intestinal goblet cell antibody was significantly higher in CD patients (23.1%) than that in UC patients (14.9%, P = 0.037). Conclusion: The findings of the current study may provide evidence-based information for Chinese gastroenterologists to treat IBD more effectively in the future.

Oncolytic Virotherapy in Peritoneal Metastasis Gastric Cancer: The Challenges and Achievements.

Gastric cancer (GC) is the fourth most common cancer and the second leading cause of cancer death globally. Although the mortality rate in some parts of the world, such as East Asia, is still high, new treatments and lifestyle changes have effectively reduced deaths from this type of cancer. One of the main challenges of this type of cancer is its late diagnosis and poor prognosis. GC patients are usually diagnosed in the advanced stages of the disease, which is often associated with peritoneal metastasis (PM) and significantly reduces survival. This type of metastasis in patients with GC poses a serious challenge due to limitations in common therapies such as surgery and tumor resection, as well as failure to respond to systemic chemotherapy. To solve this problem, researchers have used virotherapy such as reovirus-based anticancer therapy in patients with GC along with PM who are resistant to current chemotherapies because this therapeutic approach is able to overcome immune suppression by activating dendritic cells (DCs) and eventually lead to the intrinsic activity of antitumor effector T cells. This review summarizes the immunopathogenesis of peritoneal metastasis of gastric cancer (PMGC) and the details for using virotherapy as an effective anticancer treatment approach, as well as its challenges and opportunities.

[Observation on Shao's five-needle therapy as adjuvant treatment for stroke-associated pneumonia].

OBJECTIVE: To compare the therapeutic effect between Shao 's five-needle therapy combined with conventional western medical treatment and the simple conventional western medical treatment on stroke-associated pneumonia. METHODS: A total of 80 patients were randomized into an observation group and a control group, 40 cases in each group. Conventional western medication treatment i.e. anti-infection combined with rehabilitation swallowing training were adopted in the control group. On the basis of the treatment in the control group, Shao 's five-needle therapy was applied at Feishu (BL 13), Dazhui (GV 14), Fengmen (BL 12), etc. in the observation group, once a day. The treatment was given for 10 days in the both groups. The levels of inflammatory indexes [white blood cell (WBC), C-reactive protein (CRP), percentage of neutrophil (N%)] before and after treatment, the disappearance time of main clinical symptoms and signs, the scores of National Institutes of Health Stroke scale (NIHSS) and the ability of daily living (ADL) were observed, and the clinical therapeutic effect was evaluated in the both groups. RESULTS: Compared before treatment, the levels of WBC, CRP, N% and the NIHSS scores after treatment were decreased (P<0.05), the ADL scores were increased in the both groups (P<0.05), and the improvement of above indexes in the observation group was superior to the control group (P<0.05). The recovery time of temperature and rale, the duration of cough in the observation group were shorter than those in the control group (P<0.05). The effective rate was 97.5% (39/40) in the observation group, which was superior to 85.0% (34/40) in the control group (P<0.05). CONCLUSION: Shao 's five-needle therapy combined with conventional western medical treatment can effectively improve the clinical symptoms in patients with stroke-associated pneumonia, down-regulate the inflammatory indexes and improve the quality of life, the therapeutic effect is superior to the simple conventional western medical treatment.

Clinical efficacy of intravenous anesthesia on breast segmental surgery and its effects on oxidative stress response and hemodynamics of patients.

This study was designed to investigate the clinical efficacy of intravenous anesthesia on breast segmental surgery and the effects on hemodynamics of patients. A total of 267 patients were collected as research subjects. These patients underwent breast segmental surgery in Chun'an First People's Hospital from March 2015 to September 2018. Among them, 137 patients undergoing intravenous anesthesia were the research group, and 130 patients undergoing inhalation anesthesia were the control group. The following parameters were recorded: Clinical efficacy, postoperative adverse conditions, hemodynamic indicators including systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR). Visual analogue scale (VAS) was used to observe the analgesic effect of the two groups, the mental state of patients in the two groups was observed by mini-mental state examination (MMSE) scoring method, and systemic evaluation was made by oxidative stress (OS) reaction indicators. The MMSE scores of the two groups decreased one day after surgery, but the score in the research group was higher than that in the control group (P<0.05). The levels of SBP and DBP at T1 and T2 in the control group were significantly higher than those in the research group (P<0.05). HR of research group at T1 and T2 was lower than that at T0 and that at corresponding time of control group (P<0.05). The incidence rate of postoperative adverse reactions in the research group was significantly lower than that in the control group (P<0.05). In conclusion, intravenous anesthesia for breast segmental surgery can reduce the occurrence of adverse reactions after surgery, with complete sedation and analgesia. Patients were able to wake up quickly and stably after surgery, and their cognitive function and OS recovered rapidly. However, due to the great impact on hemodynamics during surgery, attention should be paid to maintain hemodynamic stability during surgery to avoid hypotension and bradycardia.

[Effect of acupuncture and moxibustion at "Feishu""Dazhui"and "Fengmen"on the expression of CC chemokine ligand 1 and CC chemokine receptor 8 in lung tissue of rats with asthma].

OBJECTIVE: To investigate the protein expression of CC chemokine ligand 1 (CCL1) and CC chemokine receptor 8 (CCR8) in the lung tissue of rats and the mechanism of acupuncture and moxibustion at "Feishu"(BL13), "Dazhui" (GV14) and "Fengmen"(BL12) in the treatment of asthma. METHODS: Sprague-Dawley rats were randomly divided into blank， model, acupuncture and moxibustion groups，n=10 in each group. Ovalbumin sensitization via intraperitoneal injection was performed to establish a model of asthma. The rats in the acupuncture group and the moxibustion group were given acupuncture for 20 min or circling moxibustion for 10 min at BL13, GV14 and BL12, once a day for 7 days. H.E. staining was used to observe the morphological changes of lung tissue. Real-time fluorescence quantitative PCR was used to measure the mRNA expression of signal transducer and activator of transcription 6 (STAT6) in lung tissue and immunohistochemistry was used to measure the protein expression of CCL1 and CCR8 in lung tissue. RESULTS: H.E. staining showed that the rats in the blank group had regular bronchial lumens and alveolar arrangement, with no inflammatory cell infiltration and aggregation around the bronchi; the rats in the model group had the infiltration and aggregation of a large number of inflammatory cells around the bronchi, stenosis of bronchial lumens, wall thickening, and alveolar structural disorder; compared with the model group, the acupuncture group and the moxibustion group had lower degrees of inflammatory cell infiltration and aggregation around the bronchi, stenosis of bronchial lumens, and wall thickening, as well as regular alveolar arrangement. The model group had significantly higher protein expression of CCL1 and CCR8 and mRNA expression of STAT6 than the blank group (P<0.05), and the acupuncture group and the moxibustion group had significantly lower protein expression of CCL1 and CCR8 and mRNA expression of STAT6 (P<0.05). CONCLUSION: Acupuncture and moxibustion can intervene against airway inflammation by inhibiting the protein expression of CCL1 and CCR8 and STAT6 signal transduction in lung tissue, which may be one of the mechanisms of acupuncture and moxibustion in the treatment of asthma.

["SHAO's five-needle method" as the main treatment for allergic rhinitis and asthma syndrome: a multi-center randomized controlled trial].

OBJECTIVE: To compare the clinical effect differences between "SHAO's five-needle method" and routine acupoint selection on allergic rhinitis and asthma syndrome. METHODS: A total of 210 patients with allergic rhinitis and asthma syndrome were randomly divided into an observation group (105 cases, 4 cases dropped off) and a control group (105 cases, 4 cases dropped off). The patients in the observation group were treated with "SHAO's five-needling method", and the acupoints of Feishu (BL 13), Dazhui (GV 14), Fengmen (BL 12), Yintang (GV 29), Shangyingxiang (EX-HN 8) and Hegu (LI 4), etc. were selected; the patients in the control group was treated with routine acupuncture, and the acupoints of Feishu (BL 13), Zhongfu (LU 1), Taiyuan (LU 9), Dingchuan (EX-B 1), Danzhong (CV 17), Yintang (GV 29), Fengmen (BL 12) and Zusanli (ST 36), etc. were selected. The treatment in the two groups was given once a day, 6 times a week, for 4 weeks. The score of symptoms and signs was observed before and after treatment as well as 1 month, 2 months and 3 months after treatment. The forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF) and eosinophils in peripheral blood were measured before and after treatment in the two groups. After treatment, the clinical therapeutic effect was compared between the two groups. RESULTS: The total effective rate was 98.0% (99/101) in the observation group, which was superior to 94.1% (95/101) in the control group (P<0.01). Compared before treatment, the total score of symptoms and signs in the two groups was significantly decreased at 1, 2, 3 and 4 weeks of treatment (P<0.01); after treatment and at each time point of follow-up, the total score of symptoms and signs in the observation group was lower than that in the control group (P<0.01). Compared with 4 weeks of treatment, the total score of symptoms and signs at each time point of follow-up was not statistically different in the observation group (P>0.05), and the total score of symptoms and signs in the third month of follow-up in the control group was significantly increased (P<0.05). After treatment, FEV1 and PEF in the two groups were increased (P<0.01), eosinophil count in peripheral blood was decreased (P<0.01), and the improvement in the observation group was greater than that in the control group (P<0.01, P<0.05). CONCLUSION: "SHAO's five-needle method" can improve the clinical symptoms and pulmonary function, reduce the count of eosinophils in peripheral blood in patients with allergic rhinitis and asthma syndrome, and the curative effect is better than routine acupuncture.

MicroRNAs and long non-coding RNAs in liver surgery: Diagnostic and therapeutic merits.

BACKGROUND: Hepatectomy and liver transplantation (LT) are the two most commonly performed surgical procedures for various hepatic lesions. microRNA (miRNA) and long non-coding RNA (lncRNA) have been gradually unveiled their roles as either biomarkers for early diagnosis or potentially therapeutic tools to manipulate gene expression in many disease entities. This review aimed to discuss the effects of miRNA or lncRNA in the hepatectomy and LT fields. DATA SOURCES: We did a literature search from 1990 through January 2018 to summarize the currently available evidence with respect to the effects of miRNA and lncRNA in liver regeneration after partial hepatectomy, as well as their involvement in several key issues related to LT, including ischemia-reperfusion injury, allograft rejection, tolerance, recurrence of original hepatic malignancies, etc. RESULTS: Certain miRNAs and lncRNAs are actively involved in the regulation of various aspects of liver resection and transplantation. During the process of liver regeneration after hepatectomy, the expression of miRNAs and lncRNAs shows dynamic changes. CONCLUSIONS: It is now clear that miRNAs and lncRNAs orchestrate in various aspects of the pathophysiological process of LT and hepatectomy. Better understanding of the underlying mechanism and future clinical trials may strengthen their positions as either biomarkers or potential therapeutic targets in the management of complications after liver surgery.

MicroRNA-214 protects L6 skeletal myoblasts against hydrogen peroxide-induced apoptosis.

MicroRNAs (miRNAs) have been reported as key gene regulators, and they control many fundamental biological processes. Previously, we demonstrated that miR-214 had a protective effect against myocardial apoptosis and myocardial fibrosis. In this study, we sought to investigate the expression of miR-214 in L6 skeletal myoblast (SKM), the regulatory effect of miR-214 on hydrogen peroxide (H2O2) induced cell apoptosis and the underlying mechanisms of the antiapoptotic effect. MiR-214 expression was up-regulated by H2O2 in a dose and time-dependent manner in L6 SKMs. To investigate the regulatory effects of miR-214 on L6 SKM, both gain-of-function and loss-of-function approaches were applied. The results showed that miR-214 improved cell survival and inhibited cell apoptosis, and blockage of miR-214 abrogated the protective effect on cell survival and resistance to apoptosis. Phosphatase and tensin homolog (PTEN) was negatively regulated by miR-214, and PTEN inhibitor obviously reversed the effect of miR-214 blockage on enhancing cell apoptosis. In addition, miR-214 up-regulated antiapoptotic protein Bcl-2, down-regulated proapoptotic protein Bax, prevented release of cytochrome c and inhibited caspase-3 activation. In summary, H2O2-induced injury increases miR-214 expression in L6 SKM, and miR-214 contributes to the protection of L6 SKM against apoptosis via lowering PTEN and subsequently inhibiting the mitochondrial-mediated caspase-dependent apoptotic signaling pathway.

Transcriptome profiling of tolerogenic dendritic cells conditioned with dual mTOR kinase inhibitor, AZD8055.

Dendritic cells (DCs) can initiate and regulate adaptive immunity depending on their maturation status. Many pharmacological and genetic means have been used in the generation of immature/tolerogenic DCs. However, the key factors controlling DCs tolerogenicity remain obscure. In this work, we demonstrated that AZD8055, an ATP-competitive inhibitor of mammalian target of rapamycin (mTOR), could also lead to a tolerogenic DC phenotype from several lines of evidence, such as suppression of T cell proliferation, promoting the generation of Tregs, and inducing allogeneic T cell apoptosis. Further studies using RNA-seq method identified 430, 1172 and 1436 differentially expressed genes (DEGs) between AZD-DCs vs. Control-DCs, LPS-DCs vs. Control-DCs, and AZD-DCs vs. LPS-DCs, respectively. The 5 most differentially expressed transcripts identified by RNA-seq expression profiles were validated by quantitative RT-PCR assays. NF-κB, p38MAPK, the ribosome and PPAR signaling pathways may be involved in the induction of tolerogenic DCs by AZD8055. Functional annotation showed some genes like MGL2, Cadherin-1, 4-1BB, RhoB and Pdpn, were quite different between AZD-DCs and Control-DCs/LPS-DCs, which might be related to the tolerogenic properties of AZD-DCs. Our work provided the potential underlying molecular mechanisms involved in the generation of tolerogenic DCs. Further functional characterization of individual target gene in DC tolerogenicity will help to develop novel therapeutic modalities in circumstances like transplant tolerance induction and autoimmunity.

Epigenetic Co-Deregulation of EZH2/TET1 is a Senescence-Countering, Actionable Vulnerability in Triple-Negative Breast Cancer.

Triple-negative breast cancer (TNBC) cells lack the expression of ER, PR and HER2. Thus, TNBC patients cannot benefit from hormone receptor-targeted therapy as non-TNBC patients, but can only receive chemotherapy as the systemic treatment and have a worse overall outcome. More effective therapeutic targets and combination therapy strategies are urgently needed to improve the treatment effectiveness. Methods: We analyzed the expression levels of EZH2 and TET1 in TCGA and our own breast cancer patient cohort, and tested their correlation with patient survival. We used TNBC and non-TNBC cell lines and mouse xenograft tumor model to unveil novel EZH2 targets and investigated the effect of EZH2 inhibition or TET1 overexpression in cell proliferation and viability of TNBC cells. Results: In TNBC cells, EZH2 decreases TET1 expression by H3K27me3 epigenetic regulation and subsequently suppresses anti-tumor p53 signaling pathway. Patients with high EZH2 and low TET1 presented the poorest survival outcome. Experimentally, targeting EZH2 in TNBC cells with specific inhibitor GSK343 or shRNA genetic approach could induce cell cycle arrest and senescence by elevating TET1 expression and p53 pathway activation. Using mouse xenograft model, we have tested a novel therapy strategy to combine GSK343 and chemotherapy drug Adriamycin and could show drastic and robust inhibition of TNBC tumor growth by synergistic induction of senescence and apoptosis. Conclusions: We postulate that the well-controlled dynamic pathway EZH2-H3K27me3-TET1 is a novel epigenetic co-regulator module and provide evidence regarding how to exploit it as a novel therapeutic target via its pivotal role in senescence and apoptosis control. Of clinical and therapeutic significance, the present study opens a new avenue for TNBC treatment by targeting the EZH2-H3K27me3-TET1 pathway that can modulate the epigenetic landscape.

Downregulation of CCR5 inhibits the proliferation and invasion of cervical cancer cells and is regulated by microRNA-107.

Cervical cancer is among the most prevalent forms of cancer worldwide. C-C chemokine receptor type 5 (CCR5) is hypothesized to be a key functional protein involved in tumorigenesis. However, the role of CCR5 in cervical cancer remains unclear. Reverse transcription-quantitative polymerase chain reaction and western blot analysis were used to evaluate the mRNA and protein expression levels of CCR5 in human cervical carcinoma tissues. Furthermore, a small interfering RNA was employed to knockdown CCR5 in HeLa and C33A cells. MTT, colony formation and Transwell assays were performed to determine the effects of this knockdown on cell viability, proliferation and invasion. In addition, micro RNA (miR)-107 was identified as a potential candidate regulator of CCR5 using miR prediction algorithms, and the effects of miR-107 and its antisense miR on CCR5 mRNA expression were determined. The results of the present study indicated that CCR5 is overexpressed in human cervical cancer tissues compared with adjacent normal tissues, and its downregulation inhibits cervical cancer cell growth and proliferation. Furthermore, the downregulation of CCR5 appears to suppress cervical cancer cell invasion. Finally, the tumor suppressor miR-107 was able to directly target CCR5 and inhibit its expression. These results suggest that the upregulation of CCR5, which is inhibited by miR-107, may play a carcinogenic role in cervical cancer and could provide a novel therapeutic target in the future.

Efficacy of acupuncture for chronic asthma: study protocol for a randomized controlled trial.

BACKGROUND: Although asthma symptoms can be temporarily controlled, it is recommended to use effective low-risk, non-drug strategies to constitute a significant advance in asthma management. Acupuncture has been traditionally used to treat asthma; however, the evidence for the efficacy of this treatment is still lacking. Previous clinical trials of acupuncture in treating asthma were limited by methodological defects; therefore, high-quality research is required. METHODS/DESIGN: This trial is designed as a multi-center, randomized, double-blind, parallel-group controlled trial. Patients with mild to moderate asthma will be randomly allocated to either a verum acupuncture plus as-needed salbutamol aerosol and/or prednisone tablets group or a sham acupuncture plus as-needed salbutamol aerosol and/or prednisone tablets group. Acupoints used in the verum acupuncture group are GV14 (Da Zhui), BL12 (Feng Men), BL13 (Fei Shu) and acupoints used in the sham acupuncture group are DU08 (Jin Suo), BL18 (Gan Shu), BL19 (Dan Shu). After a baseline period of 1 week, the patients in both groups will receive verum/sham acupuncture once every other day with a total of 20 treatment sessions in 6 weeks and a 3-month follow-up. The primary outcome will be measured by using the asthma control test and the secondary outcomes will be measured by using the percentage of symptom-free days, the average dosage of salbutamol aerosol and/or prednisone tablets, lung functions, daily asthma symptom scores, asthma quality of life questionnaire, and so on. DISCUSSION: This trial will assess the effect of acupuncture on asthma and aims to provide reliable clinical evidence for the efficacy of acupuncture in treating asthma. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01931696 , registered on 26 August 2013.

Transcription factors GATA4 and TBX5 promote cardiomyogenic differentiation of rat bone marrow mesenchymal stromal cells.

Bone marrow mesenchymal stromal cells (BMSCs) have potential applications in cell and gene therapies for cardiac disease. The cardiac-specific transcription factors GATA-binding protein 4 (GATA4) and T-Box protein 5 (TBX5) are considered to be pivotal in cardiogenesis. The aim of this study was to investigate the effects of GATA4 and TBX5 on cardiomyogenic differentiation of BMSCs. The BMSCs were initially isolated and identified. Vectors harboring cardiac transcription factor genes GATA4 and TBX5 or empty vectors were transferred into BMSCs. Cardiomyogenic cells differentiated from BMSCs were identified by expression of cardiac-specific markers including cardiac troponin T, connexin 43, ß-myosin heavy chain, and myosin light chain-2 using immunocytochemical staining, western blotting, and quantitative real-time PCR. The ultrastructures of the differentiated cells were examined by transmission electron microscopy, which were similar to those of fetal cardiomyocytes. The differentiated cells exhibited L-type calcium current activities reflective of the electrophysiological characteristics of cardiomyocytes. These findings indicate that exogenous expression of cardiac-specific transcription factors GATA4 and TBX5 enhance cardiomyogenic differentiation of BMSCs.

[Effect of acupuncture intervention on airway remodeling and transforming growth factor-beta1 expression in asthma rats].

OBJECTIVE: To observe the effect of acupuncture stimulation of "Dazhui" (GV 14), bilateral "Fengmen" (BL 12) and "Feishu" (BL 13) on the thickness of the bronchial tubal wall and smooth muscle and expression of transforming growth factor-beta1 (TGF-beta1) in asthma rats so as to reveal its mechanism underlying improvement of asthma. METHODS: Forty SD rats were randomly assigned to control, model, acupuncture and medication groups. The asthma model was induced by subcutaneous injection of 1% egg albumin solution and forced inhalation of atomized ovalbumin. Rats of the acupuncture group were treated by acupuncture stimulation of GV 14, bilateral BL 12 and BL 13 (once daily for 10 days), and rats of the medication group treated by intraperitoneal injection of Aminophylline Injection (100 mg/kg, once daily for 10 days). The thickness of the bronchial tubal wall and airway smooth muscle of the lung tissue were measured by image analyzer for assessing the degree of airway remodeling. The expression of TGF-beta1 in the small airway was detected by immunohistochemistry. RESULTS: Compared to the control group, the thickness of the airway wall and smooth muscle, and the expression level of TGF-beta1 were remarkably increased in the model group (P < 0.01). After acupuncture intervention and medication treatment, the thickness of the airway wall and smooth muscle, and the expression level of TGF-beta1 were remarkably down-regulated in both groups in comparison with those of the model group (P < 0.05, P < 0.01), and the expression of TGF-beta1 in the acupuncture group was obviously lower than that of the medication group (P < 0.05). CONCLUSION: Acupuncture stimulation of GV 14, bilateral BL 12 and BL 13 can down-regulate bronchial asthma-induced increase of TGF-[, expression in the lung tissue in asthma rats, which may contribute to its effect in improving airway remodeling.

[Discussion on professor SHAO Jing-Ming's academic opinion of focusing spirit].

During professor SHAO Jing-ming's academic research and medical practice, his academic opinion of focusing spirit is gradually developed. In terms of nurturing the spirit, attention should be paid on persistence as well as everyday health maintenance and exercise to nurture the spirit of physician. In terms of clinical diagnosis and treatment, patients' psychology, employment and life status should be observed and experienced, which could bring more methods to take essential care of patients' spirit. The treatment should work with psychological counseling, advocating that based on patients' qi and spirit, various forms of treatment methods should be properly used, such as acupuncture or moxibustion or combination of acupuncture and medicine, along with simple acupoint selection and harmony medication. Before clinical treatment of acupuncture, calming the mind is critically emphasized to make a clear diagnosis. During the acupuncture, calming and focusing the mind is necessary as well as emphasizing the details, so acupuncture could be integrated with Chi Gong to create a new warming-sensation technique. In a word, the academic opinion of focusing spirit is shedding an inspiring light upon further study.
