ABSTRACT
OBJECTIVE@#To investigate the evolution of herbal medicine in treating tuberculosis (TB) and encourage anti-TB drug discovery and development.@*METHODS@#In this study, 477 ancient traditional Chinese medicine formulae were collected from the Dictionary of Traditional Chinese Medicine Prescriptions and 172 modern Chinese medicine formulae (from 1986 to 2016) were collected by searching 4 databases: WanFang Data Knowledge Service Platform, China National Knowledge Infrastructure Database (CNKI), China Science and Technology Journal Database (VIP) and Chinese Bio-medical Literature and Retrieval System (SinoMed) in Chinese. We restricted the search to publications in Chinese. Further data analysis was done using the Traditional Chinese Medicine Inheritance Support System version 2 Software.@*RESULTS@#There were 425 herbs in the 477 ancient formulae and 257 herbs in the 172 modern formulae. Half of the top 30 herbs were shared by both modern and ancient prescriptions. They are Radix Ophiopogonis, Astragalus membranaceus, Fritillaria cirrhosa, Dried rehmannia glutinosa, Poria cocos, Angelica sinensis, Prepared rehmannia glutinosa, Platycodon Root, Radix paeoniae alba, Schisandra chinensis, Bighead atractylodes rhizome, Rhizoma anemarrhenae, Cortex lycii radicis and Radix Scutellariae. Only two groups of herbs with a high correlation coefficient were found in both modern and ancient prescriptions, the Dried rehmannia glutinosa with Radix ophiopogonis, and Radix ophiopogonis with Prepared rehmannia glutinosa. There were 9 and 15 core herb combinations in modern and ancient prescriptions, respectively, but no one was found simutaniously in both modern and ancient prescriptions.@*CONCLUSIONS@#Although there were wide variations in the herb groups and herb combinations in the formulae, half of the top 30 herbs were found in both modern and ancient prescriptions. The core herb combinations in modern and ancient prescriptions could help us to improve the priscription for treatment of TB.
ABSTRACT
Objective:To evaluate the clinical efficacy of modified Sini Powder combined with acupoint application in the treatment of liver depression and spleen deficiency syndrome of diarrhea irritable bowel syndrome(IBS-D). Methods:A total of 104 IBS-D patients with liver depression and spleen deficiency syndrome in our hospital from October 2018 to December 2020 were randomly divided into two groups according to the random number table method, 52 in each group. Both groups took montmorillonite powder orally first. On this basis, the control group was treated with pivirium bromide tablets, and the study group was treated with Modified Sini Powder combined with acupoint application. Both groups were treated for 4 weeks. TCM symptom scores were performed before and after treatment. The levels of serum IL-6, IL-8 and TNF-α were detected by ELISA. The recovery time of stool characteristics, the disappearance time of abdominal pain and the recovery time of stool times were observed and recorded, and the clinical curative effect was evaluated. Results:The total effective rate was 92.3% (48/52) in the observation group and 75.0% (39/52) in the control group, there was significant difference between the two groups ( χ2=5.696, P=0.017). After treatment, the scores of abdominal pain, diarrhea, stool frequency, irritability, mental fatigue and hypochondriac pain in the observation group were significantly lower than those in the control group ( t values were 15.492, 16.827, 13.419, 10.831, 14.736,12.437, respectively, all Ps<0.001), and the levels of serum IL-6, IL-8 and TNF-α were significantly lower than those in the control group ( t values were 16.390, 21.528 and 18.734, respectively, all Ps<0.001). The recovery time of stool characteristics [(3.79 ± 0.63) d vs. (4.84 ± 0.79) d, t=7.493], the disappearance time of abdominal pain [(2.63 ± 0.32) d vs. (3.91 ± 0.37) d, t=18.869], and the recovery time of stool times [(3.26 ± 0.57) d vs. (4.19 ± 0.68) d, t=7.558] in the observation group were significantly shorter than those in the control group ( P<0.01). Conclusion:Modified Sini Powder combined with acupoint application can improve the clinical symptoms of IBS-D patients with liver depression and spleen deficiency syndrome, reduce the level of serum inflammatory cytokines and improve the curative effect.
ABSTRACT
BACKGROUND@#Ubiquitin-conjugating enzyme E2C (UBE2C) has been shown to be associated with the occurrence of various cancers and involved in many tumorigenic processes. This study aimed to investigate the specific molecular mechanism through which UBE2C affects breast cancer (BC) proliferation.@*METHODS@#BC-related datasets were screened according to filter criteria in the Gene Expression Omnibus (GEO) database and The Cancer Genome Atlas (TCGA) database. Then differentially expressed genes (DEGs) were identified using Venn diagram analysis. By using DEGs, we conducted the following analyses including Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), protein-protein interaction (PPI), and survival analysis, and then validated the function of the hub gene UBE2C using quantitative reverse transcription-polymerase chain reaction (RT-qPCR), cell counting kit-8 (CCK-8) assay, transwell assay, and Western blot assay.@*RESULTS@#In total, 151 DEGs were identified from the GEO and TCGA databases. The results of GO analysis demonstrated that the DEGs were significantly enriched with mitotic nuclear division, lipid droplet, and organic acid-binding. KEGG analysis showed that the peroxisome proliferators-activated receptor (PPAR) signaling pathway, regulation of lipolysis in adipocytes, and proximal tubule bicarbonate reclamation were significantly enriched in the signal transduction pathway category. The top three hub genes that resulted from the PPI network were FOXM1, UBE2C, and CDKN3. The results of survival analysis showed a close relationship between UBE2C and BC. The results of CCK-8 and transwell assays suggested that the proliferation and invasion of UBE2C knockdown cells were significantly inhibited (P < 0.050). The results of Western blot assay showed that the level of phosphorylated phosphatase and tensin homology deleted on chromosome 10 (p-PTEN) was obviously increased (P < 0.050), whereas the levels of phosphorylated protein kinase B (p-AKT), phosphorylated mammalian target of rapamycin (p-mTOR), and hypoxia-inducible factor-1 alpha (HIF-1α) were dramatically decreased (P < 0.050) in the UBE2C knockdown cell.@*CONCLUSION@#UBE2C can promote BC proliferation by activating the AKT/mTOR signaling pathway.

OBJECTIVE@#To establish the aGVHD mouse model，and investigate the regulatory effect and its mechanism of low-dose GSI combined with BMSC on aGVHD mice.@*METHODS@#C57BL/6 (H-2b) and BALB/c (H-2d) were selected as donor and recipient of allogeneic transplantation to establish the aGVHD mouse model. BALB/c mice were randomly divided into 6 groups, which were the bone marrow cell infusion after irradiation (BM) group; the bone marrow cells + spleen cells after irradiation (BM+SC) group; the bone marrow cells + spleen cells + DMSO (BM+SC+DMSO) (transplant control) group; bone marrow cells + splenocytes +GSI after irradiation (BM+SC+GSI) group; bone marrow cells + spleen cells + bone marrow mesenchymal stromal infusion after irradiation cell (BM+SC+BMSC) group; bone marrow cells + spleen cells + bone marrow mesenchymal stromal cells +GSI infused after irradiation (BM+SC+BMSC+GSI) group. The mice in the two groups containing GSI were intraperitoneally injected with GSI at 5 μmol/kg on day 1, 2, and 3 after transplantation with DMSO as a control. The general conditions, survival time and hematopoietic recovery of mice were observed, cytokines were detected by ELISA, and histopathological changes were detected by immunohistochemistry. The effects of low-dose GSI combined with BMSC on hematopoietic reconstruction and aGVHD development after allo-BMT were investigated.@*RESULTS@#The survival rate of the mice in BM+SC+BMSC+GSI combination group was 80% during the observation period, which was significantly higher than that in the other groups; the incidence of aGVHD was reduced in the BMSC GSI or their combination groups after 21 days of transplantation. GSI could partly promote the recovery of leukocytes, and show no significant delayed effect on the recovery platelets. Moreover, the level of Th1 cytokines (IFN-γ) in BM+SC+BMSC+GSI combined group was lower than that in BM+SC+GSI group (P<0.01), the level of Th2 cytokines (IL-4) in the combination group was higher than that in BM+SC+GSI group (P<0.01), also the level of IL-17 was significantly lower than that in the corresponding control group (P<0.001).@*CONCLUSION@#Low dose GSI combined with BMSC can promote hematopoietic reconstruction and regulate cytokines secretion including IFN-γ, IL-4 and IL-17. GSI combined with BMSC achieve the goal of synergistically inhibiting the occurrence and progression of aGVHD.

Objective:To study the effect of long noncoding RNA growth arrest-specifific transcript 5 (lncRNA GAS5) on the occurrence and development of triple-negative breast cancer (TNBC) by analyzing the differential expression of lncrna GAS5 in The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases.Methods:The expression of GAS5 in each subtype and pathological stage of breast cancer was studied by the TCGA data. The correlation of GAS5 was analyzed by using TNBC data GSE76124 and GSE83937 from the GEO database of the United States. The elated genes were collected and take the intersection. The positive correlation genes were used to analyze the GO function and the enrichment of KEGG pathway. GSEA of GAS5 was analyzed with TCGA database and GEO76124 data. GSE40525 and GSE76250 were selected from GEO data set to screen different miRNA and mRNA of TNBC, and construct the ceRNA network of GAS5-mirna-mrna through prediction.Results:The expression of GAS5 in breast cancer was lower than that in the adjacent tissues. GAS5 was mainly involved in various metabolic processes, including organic metabolism, macromolecular metabolism, nitrogen metabolism, etc. In terms of pathway, GAS5 mainly affected the ribosome biogenesis in eukaryotes, Wnt signaling pathway. By constructing the regulatory network of GAS5 in TNBC, we found that GAS5 was most likely to regulate the expression of 25 genes including SLC7A2 and lLONRF2 by adsorbing hsa-mir-650 and has-mir-532-5p.Conclusion:lncrna GAS5 may play a role of tumor suppressor gene in breast cancer and provide a new therapeutic target for gene therapy of breast cancer.

ABSTRACT
Objective:To evaluate the safety, feasibility and operational performance of self-developed medical disposable portable endoscopy (YunSendo) for upper gastrointestinal endoscopy examination in Ba-Ma mini-pigs.Methods:A total of 10 Guangxi Ba-Ma mini-pigs were used in the experiment, and mucosal injury models were established in advance by biopsy forceps in esophagus, stomach, and duodenum. Each experimental animal underwent medical disposable portable endoscopy and Olympus endoscopy (GIF-Q260J) performed by two endoscopists separately. The time when the endoscope reached the duodenum, the number of detected mucosal injuries and endoscopic pictures of different parts with standard image acquisition were recorded. Endoscopic operational performance and endoscopic image quality were evaluated. Different endoscopists recorded experimental results with blind method. The procedures of the two endoscopic examinations were performed by coin-tossing method. The paired t test was used for statistical analysis. Results:There were no statistically significant differences in the insertion time and total operation time between medical disposable portable endoscopy and Olympus endoscopy ( (171.00±9.96) s vs. (164.00±17.84) s, (285.00±33.94) s vs. (273.40±23.46) s; t=1.289 and 1.281, P=0.230 and 0.232). There were no statistically significant differences in the percentage of time of clear visual field during endoscopy insertion and total operation between medical disposable portable endoscopy and Olympus endoscopy ((91.83±1.85)% vs. (91.52±1.51)%, (93.07±3.10)% vs. (92.06±2.57)%; t=0.401 and 0.689, P=0.698 and 0.508). Moreover, there were no statistically significant differences in the score of comprehensive operation performance, score of clear image number, score of image color recognition, score of image illumination, comprehensive score of image quality and number of detected mucosal injuries ((9.66±0.30) points vs. (9.86±0.15) points, (39.50±0.71) points vs. (39.30±1.06) points, (39.70±0.48) points vs. (39.40±0.70) points, (39.40±0.70) points vs. (39.50±0.71) points, (9.88±0.09) points vs. (9.85±0.20) points, 9.80±0.42 vs. 9.90±0.32; t=2.176, 1.000, 1.152, 0.317, 0.629 and 0.557, all P>0.05). There were no adverse events after operation in medical disposable portable endoscopy group and Olympus endoscopy group. Conclusions:The medical disposable portable endoscopy is safe and feasible for endoscopy examination in live animal models. Different parts of upper gastrointestinal tract and mucosal lesions can be clearly detected. The operational performance and the image quality are excellent, which is similar to Olympus endoscopy (GIF-Q260J).
ABSTRACT
Although opioids still remain the most powerful pain-killers, the chronic use of opioid analgesics is largely limited by their numerous side-effects, including opioid dependence. However, the mechanism underlying this dependence is largely unknown. In this study, we used the withdrawal symptoms precipitated by naloxone to characterize opioid dependence in mice. We determined the functional role of mu-opioid receptors (MORs) expressed in different subpopulations of neurons in the development of morphine withdrawal. We found that conditional deletion of MORs from glutamatergic neurons expressing vesicular glutamate transporter 2 (Vglut2) largely eliminated the naloxone-precipitated withdrawal symptoms. In contrast, conditional deletion of MORs expressed in GABAergic neurons had a limited effect on morphine withdrawal. Consistently, mice with MORs deleted from Vglut2 glutamatergic neurons also showed no morphine-induced locomotor hyperactivity. Furthermore, morphine withdrawal and morphine-induced hyperactivity were not significantly affected by conditional knockout of MORs from dorsal spinal neurons. Taken together, our data indicate that the development of morphine withdrawal is largely mediated by MORs expressed in Vglut2 glutamatergic neurons.

ABSTRACT
To investigate the risk factors associated with acute renal failure (ARF) after thoracoabdominal aortic aneurysm (TAAA) surgery. A total of 156 patients underwent TAAA repair between January 2009 and December 2017. Renal failure was defined based on the Kidney Disease Improving Global Outcomes criteria. The patients were divided into ARF group and non-ARF group based on the presence/absence of postoperative ARF. The risk factors of ARF were analyzed by univariate analysis and multivariate logistic analysis. The subjects included 111 males and 45 females aged (40.4±10.9) years (range:19-65 years). The surgical reasons included aortic dissection (=130,83.3%),aneurysm (=22,14.1%),and pseudoaneurysm (=4,2.6%). The degrees of repair included Crawford extent I in 6 patients (3.8%),extent Ⅱ in 128 patients (82.1%),extent Ⅲ in 20 patients (12.8%),and extent Ⅳ in 2 patients(1.3%). There were 3 patients presented with aortic rupture and 6 patients received emergent operations. Nine patients (5.8%) died within 30 days after surgery,and 8 patients (5.1%) suffered from permanent paraplegia. Thirty-six patients (23.1%) had ARF after surgery,and 18 of them needed dialysis. Multivariate logistic analysis showed that smoking ( =2.637,95%=1.113-6.250,=0.028),packed red blood cell usage in operation (≥6 U) ( =5.508,95%=2.144-11.930,=0.000),reoperation for bleeding (=3.529,95%=1.298-9.590,=0.013) were independent risk factors for ARF after TAAA repair. Smoking,packed red blood cell usage in operation (≥6 U),reoperation for bleeding are the independent risk factors of ARF after TAAA surgery.

Proton pump inhibitors (PPIs) are commonly used to lessen symptoms in patients with gastroesophageal reflux disease (GERD). However, the effects of PPI therapy on the gastrointestinal microbiota in GERD patients remain unclear. We examined the association between the PPI usage and the microbiota present in gastric mucosal and fecal samples from GERD patients and healthy controls (HCs) using 16S rRNA gene sequencing. GERD patients taking PPIs were further divided into short-term and long-term PPI user groups. We showed that PPI administration lowered the relative bacterial diversity of the gastric microbiota in GERD patients. Compared to the non-PPI-user and HC groups, higher abundances of Planococcaceae, Oxalobacteraceae, and Sphingomonadaceae were found in the gastric microbiota from the PPI-user group. In addition, the Methylophilus genus was more highly abundant in the long-term PPI user group than in the short-term PPI-user group. Despite the absence of differences in alpha diversity, there were significant differences in the fecal bacterial composition of between GERD patients taking PPIs and those not taking PPIs. There was a higher abundance of Streptococcaceae, Veillonellaceae, Acidaminococcaceae, Micrococcaceae, and Flavobacteriaceae present in the fecal microbiota from the PPI-user group than those from the non-PPI-user and HC groups. Additionally, a significantly higher abundance of Ruminococcus was found in GERD patients on long-term PPI medication than that on short-term PPI medication. Our study indicates that PPI administration in patients with GERD has a significant effect on the abundance and structure of the gastric mucosal microbiota but only on the composition of the fecal microbiota.

BACKGROUND@#Irritable bowel syndrome (IBS) is one of the most common functional intestinal diseases, but its pathogenesis is still unknown. The present study aimed to screen the differentially expressed proteins in the mucosa of colon between IBS with diarrhea (IBS-D) patients and the healthy controls.@*METHODS@#Forty-two IBS-D patients meeting the Rome III diagnostic criteria and 40 control subjects from July 2007 to June 2009 in Chinese PLA General Hospital were enrolled in the present study. We examined the protein expression profiles in mucosa of colon corresponding to IBS-D patients (n = 5) and controls (n = 5) using 2-dimensional gel electrophoresis (2-DE) and mass spectrometry (MS). Secondly, Western blot and immunohistochemical analysis were carried out to validate the screened proteins in 27 IBS-D patients and 27 controls. Thirdly, high-performance liquid chromatography (HPLC) was further carried out to determine ATP concentration in the mucosa of colon between 10 IBS-D patients and 8 controls. Comparisons between 2 groups were performed by Student's t-test or Mann-Whitney U-test.@*RESULTS@#Twelve differentially expressed proteins were screened out. The α-enolase (ENOA) in the sigmoid colon (0.917 ± 0.007 vs. 1.310 ± 0.100, t = 2.643, P = 0.017) and caecum (0.765 ± 0.060 vs. 1.212 ± 0.122, t = 2.225, P = 0.023), Isobutyryl-CoA dehydrogenase (ACAD8) in the sigmoid colon (1.127 ± 0.201 vs. 1.497 ± 0.392, t = 7.093, P = 0.008) of the IBS-D group were significantly lower while acetyl-CoA acetyltransferase (CT) in the caecum (2.453 ± 0.422 vs. 0.931 ± 0.652, t = 8.363, P = 0.015) and ATP synthase subunit d (ATP5H) in the sigmoid (0.843 ± 0.042 vs. 0.631 ± 0.042, t = 8.613,P = 0.007) of the IBS-D group was significantly higher, compared with the controls. The ATP concentration in the mucosa of the sigmoid colon in IBS-D group was significantly lower than that of control group (0.470 [0.180, 1.360] vs. 5.350 [2.230, 7.900], U = 55, P < 0.001).@*CONCLUSIONS@#Many proteins related to energy metabolism presented differential expression patterns in the mucosa of colon of the IBS-D patients. The abnormalities in energy metabolism may be involved in the pathogenesis of IBS which deserves more studies to elucidate.

OBJECTIVE@#To evaluate the efficacy and safety of salvianolate in elderly patients with unstable angina pectoris (UAP).@*METHODS@#A prospective double-blind randomized placebo-controlled multicenter trial in elderly patients with UAP from 13 third-grade class-A hospitals in China was performed. A total of 318 patients were randomly allocated in a 1:1 ratio to an experimental group (160 patients) and a control group (158 patients). The experimental group was treated with salvianolate for 14 days on the basis of conventional medicine, and the control group was given a placebo for 14 days with the same criteria. Follow-up was lasted 28 days in both groups. The primary endpoint was biweekly frequency of angina pectoris attacks. The secondary endpoints included biweekly dosage of nitroglycerin, the Seattle Angina Questionnaire, angina pectoris severity and duration, myocardial injury markers, high-sensitivity C-reactive protein (hs-CRP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP), as well as major adverse cardiovascular events (MACEs). Safety was assessed according to adverse events and serious adverse events.@*RESULTS@#Baseline characteristics were similar between treatment groups. Compared with those in the control group, the frequency of biweekly angina attacks (2.92 vs . 4.08, P=0.025), the biweekly dosage of nitroglycerin, as well as the severity and duration of angina attacks (P<0.01) were reduced by salvianolate. The Seattle Angina Questionnaire score was also significantly improved in the experimental group than in the control group (P<0.05). No significant differences were observed between the two groups with respect to the incidence of MACEs. Salvianolate was well tolerated.@*CONCLUSIONS@#Salvianolate appear to have efficacy and well tolerated for elderly patients with UAP. [ClinicalTrials.gov identifier: NCT03037047].
ABSTRACT
Objective To evaluate the early and midterm results of surgical repair of thoracoabdominal aortic aneurysm(TAAA)in patients with Marfan syndrome(MFS). Methods The clinical data of patients with MFS undergoing TAAA repair in Fuwai Hospital between January 2009 and December 2017 were retrospectively analyzed.These patients were divided into two groups:MFS group(=58)and non-MFS group(=98).The baseline data,early postoperative results,and midterm follow-up outcomes were compared between these two groups. Results MFS patients were significantly younger(32 years old 45 years old,=9.603,=0.000)and more frequently had a history of aortic aneurysm or dissection(19% 0,=19.996,=0.000)than non-MFS patients.However,the proportions of males and smokers were significantly lower when compared with non-MFS patients(55.2% 80.6%,=11.489,=0.001;13.8% 46.9%,=17.686,=0.001).There was no significant difference in proportion of emergency operation,prophylactic cerebrospinal fluid drainage,operation time,intra-operative circulation management,and intra-operative blood transfusion(all >0.05).The 30-day mortality rate was significantly lower in MFS group than in non-MFS group(0 9.2%, [Formula: see text]=5.034,=0.025). Conclusions For patients with MFS,TAAA repair provides lower 30-day mortality and comparative middle-term survival.However,the re-intervention rate is higher among MFS patients,highlighting the importance of close follow-up.

The fetal membranes, consisting of amnion and chorion, cover approximately 70% of the uterine cavity. Accumulating evidence indicates that the fetal membranes are not mere degenerating tissues covering the amniotic fluid and the fetus, but one of the most important functional tissues during pregnancy. The fetal membranes not only protect the fetus, but also secrets a series of hormones and cytokines involved in pregnancy maintenance and fetal development as well as the initiation of labor. Early activation of fetal membranes such as chorioamnionitis will lead to preterm birth.

ABSTRACT
Objective To investigate the impact of multi-b-value on texture features of DWI in liver cirrhosis.Methods DWI manifestations of liver cirrhosis in 37 patients were analyzed retrospectively,and DWI of 27 healthy volunteers (control group) were enrolled as controls.The b values were set as 0,20,50,100,200,400,800,1 000,1 200 and 1500 s/mm2,respectively.Three ROIs at different levels of every set image were selected,and 37 texture features within these ROIs were extracted.Unstable texture features affected by different b-values were screened with the percent coefficient of variation (％COV),and the fitting degree between the unstable texture features and b values were analyzed with exponential fitting.Results Among 37 texture features,20 (20/37,54.05 ％) were unstable.With the increase of b values,exponential upward trend was found in 10 texture features,exponential downward trend was found in 4 texture features,and the relative trends could not be defined in other 6 unstable texture features.Conclusion The b values of DWI impact the texture features in liver cirrhosis.Correlations exist among some texture features and b values.
ABSTRACT
Objective To investigate the influence of preoperative biopsy protocols difference on the material amount and operation time of patients with gastric cancer for early stage underwent ESD. Methods 60 patients with gastric cancer for early stage underwent ESD were chosen from June 2013 to June 2016 and randomly divided into A group (30 patients) with multiple times and points biopsies and B group (30 patients) with targeted biopsy before surgery; the biopsy number, the total number of specimens, the postoperative pathological coincidence rate and the ESD operation time of the two groups were compared. Results The biopsy number and the total number of specimens of B group were significant shorter than that in A group (P < 0.05). The postoperative pathological coincidence rate of B group were significant higher than that in A group (P < 0.05). There was no significant difference in the time of resection range determined, labeling, submucosal injection and specimen resection handling between the two groups (P > 0.05). The time of mucous membrane dissection, hemostasis and wound handling of B group were significant shorter than that in A group (P < 0.05). Conclusion Compared with multiple times and points biopsies, targeted biopsy before surgery on patients with gastric cancer for early stage underwent ESD can efficiently reduce the trauma degree, improve the biopsy accuracy and be helpful to shorten the operation time.
ABSTRACT
Objective To observe the clinical efficacy of Tiao Shen Jie Jing needling (regulating the mind and release spasm) in treating post-stroke upper-limb spastic palsy. Method Ninety patients with post-stroke upper-limb spastic palsy were randomized into an observation group and a control group, 45 cases each. The observation group was intervened by Tiao Shen Jie Jing needling, while the control group was given ordinary acupuncture. The Modified Ashworth Scale (MAS), short-form Fugl-Meyer Assessment (SFMA) and Barthel Index (BI) were evaluated and recorded prior to the treatment, after 2-week and 4-week treatment and 3 months later after the intervention; the serumγ-aminobutyric acid (GABA) was detected before and after the treatment. Result The total effective rate was 83.3% in the observation group versus 61.0% in the control group, and the efficacy of the observation group was superior to that of the control group (P<0.05). The scores of each scale showed improvements after the treatment in both groups (P<0.05), and the improvements in the observation group were more significant (P < 0.05). The follow-up showed continuing improvements in the scales in the observation group, which were superior to those in the control group (P<0.05); after the treatment, the content of GABA in the observation group was significantly higher than that in the control group (P<0.05). Conclusion Tiao Shen Jie Jing needling can effectively ameliorate the upper-limb spasm,as well as the motor function of the upper extremities, improve the activities of daily living and maintain a long-term efficacy, better than ordinary acupuncture. The action mechanism is related to the regulation of GABA content in serum.
