RESUMEN
BACKGROUND: Postprandial distress syndrome (PDS) is the most common subtype of functional dyspepsia. Acupuncture is commonly used to treat PDS, but its effect is uncertain because of the poor quality of prior studies. OBJECTIVE: To assess the efficacy of acupuncture versus sham acupuncture in patients with PDS. DESIGN: Multicenter, 2-group, randomized clinical trial. (ISRCTN registry number: ISRCTN12511434). SETTING: 5 tertiary hospitals in China. PARTICIPANTS: Chinese patients aged 18 to 65 years meeting Rome IV criteria for PDS. INTERVENTION: 12 sessions of acupuncture or sham acupuncture over 4 weeks. MEASUREMENTS: The 2 primary outcomes were the response rate based on overall treatment effect and the elimination rate of all 3 cardinal symptoms: postprandial fullness, upper abdominal bloating, and early satiation after 4 weeks of treatment. Participants were followed until week 16. RESULTS: Among the 278 randomly assigned participants, 228 (82%) completed outcome measurements at week 16. The estimated response rate from generalized linear mixed models at week 4 was 83.0% in the acupuncture group versus 51.6% in the sham acupuncture group (difference, 31.4 percentage points [95% CI, 20.3 to 42.5 percentage points]; P < 0.001). The estimated elimination rate of all 3 cardinal symptoms was 27.8% in the acupuncture group versus 17.3% in the sham acupuncture group (difference, 10.5 percentage points [CI, 0.08 to 20.9 percentage points]; P = 0.034). The efficacy of acupuncture was maintained during the 12-week posttreatment follow-up. There were no serious adverse events. LIMITATION: Lack of objective outcomes and daily measurement, high dropout rate, and inability to blind acupuncturists. CONCLUSION: Among patients with PDS, acupuncture resulted in increased response rate and elimination rate of all 3 cardinal symptoms compared with sham acupuncture, with sustained efficacy over 12 weeks in patients who received thrice-weekly acupuncture for 4 weeks.

OBJECTIVE:: To evaluate the effectiveness of acupuncture for pain relief and function improvement in patients with knee osteoarthritis and to determine the feasibility of an eight-week acupuncture intervention. DESIGN:: Pilot randomized controlled trial. SETTING:: Three teaching hospitals in China. SUBJECTS:: Patients with knee osteoarthritis (Kellgren grade II or III). INTERVENTIONS:: Patients were randomly assigned to an eight-week (three sessions per week) intervention of either traditional Chinese acupuncture or sham acupuncture. MAIN MEASURES:: The primary outcome was response rate-the proportion of patients achieving score ⩾36% decrease in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and function at week 8 compared with baseline. Secondary outcomes included pain, function and quality of life. RESULTS:: Of 42 patients randomized, 36 (85.7%) completed the study. There was no significant difference in response rate between the traditional Chinese acupuncture and control groups: 61.9% (13 of 21) versus 42.9% (9 of 21) achieved score ⩾36% decrease in WOMAC pain and function at week 8 ( P = 0.217). The sum of WOMAC pain and function scores at week 8 was 11.6 (9.1) in the traditional Chinese acupuncture group compared with 16.3 (10.9) in the control group ( P = 0.183). There was no significant difference between groups. Three adverse events were recorded and were classified as mild. CONCLUSION:: It showed that three sessions per week acupuncture intervention of knee osteoarthritis was feasible and safe. No difference was observed between groups due to small sample size. Larger (sample size ⩾ 296) randomized controlled trials of this intervention appear justified.

OBJECTIVE: To explore the mechanism of electroacupuncture (EA) at "Zusanli" (ST36) on improving glucose metabolism disorder in chronic restraint induced depressed rats. METHODS: A total of 30 male SD rats were randomly divided into control, model and EA groups, with 10 rats in each group. The depression model was established by chronic restraint 2.5 h each day for 4 weeks. For rats in the EA group, EA stimulation (1 mA, 2 Hz, 30 min) was applied to bilateral ST36 during the modeling period, once a day for 4 weeks. The body weight of the rats was recorded before and after modeling. The behavior of rats was observed by sugar-water preference and forced swimming after modeling. The contents of glucose and glycosylated albumin in serum were determined by biochemical method. The histopathological morphology and liver glycogen content were observed by HE and PAS staining. The expression levels of phosphatidylinositol 3-kinase (PI3K), phosphorylated (p)-PI3K (p-PI3K), protein kinase B (Akt), p-Akt, glycogen synthase kinase-3ß (GSK3ß) and p-GSK3ß proteins in liver were determined by Western blot. RESULTS: Compared with the control group, the weight increment and sugar-water preference index decreased (P<0.01), the immobile swimming time was prolonged (P<0.01), the glucose and glycosylated albumin contents in serum increased (P<0.05), the expression of p-Akt protein and the ratio of p-Akt/Akt in liver tissues decreased (P<0.001), the expression of p-GSK3ß protein and the ratio of p-GSK3ß/GSK3ß in liver tissues increased (P<0.01,P<0.001) in the model group. Compared with the model group, the weight increment and sugar-water preference index increased (P<0.05), the immobile swimming time was shortened (P<0.05), the glucose and glycosylated albumin contents in serum decreased (P<0.05), the expressions of p-PI3K and p-Akt proteins and the ratio of p-PI3K/PI3K and p-Akt/Akt in liver tissues increased (P<0.05), the expression of p-GSK3ß protein and the ratio of p-GSK3ß/GSK3ß in liver tissues decreased (P<0.01) in the EA group. HE staining showed that the structure of the hepatic lobule was intact, no obvious inflammatory cell infiltration or fibrosis was observed in the lobule and interstitium, and no abnormalities were observed in the small bile duct, portal vein and artery in the portal area. PAS staining showed that the intensity of staining from the center of the hepatic lobule to the periphery of the hepatic lobule was gradually enhanced in the blank group, that is, the glycogen-rich granules in the hepatic cells were gradually increased; most of the hepatocytes were light colored and glycogen was lost significantly in the model group; while the intensity of hepatocyte staining increased, the staining intensity of the perilobular zone was weaker than that in the blank group, and the glycogen particles partially recovered in the EA group. CONCLUSION: EA intervention can regulate glucose metabolism disorder in chronic restraint induced depressed rats through PI3K/Akt/GSK3ß signaling pathway.

Importance: Despite the adoption of the optimized Enhanced Recovery After Surgery (ERAS) protocol, postoperative ileus (POI) severely impairs recovery after colorectal resection and increases the burden on the health care system. Objective: To assess the efficacy of electroacupuncture (EA) in reducing the duration of POI with the ERAS protocol. Design, Setting, and Participants: This multicenter, randomized, sham-controlled trial was conducted in China from October 12, 2020, through October 17, 2021. There was a 1:1 allocation using the dynamic block random method, and analyses were by intention to treat. Patients 18 years or older undergoing laparoscopic resection of colorectal cancer for the first time were randomly assigned to treatment group by a central system. Interventions: Patients were randomly assigned to 4 sessions of EA or sham electroacupuncture (SA) after surgery. All patients were treated within the ERAS protocol. Main Outcomes and Measures: The primary outcome was the time to first defecation. Secondary outcomes included other patient-reported outcome measures, length of postoperative hospital stay, readmission rate within 30 days, and incidence of postoperative complications and adverse events. Results: A total of 249 patients were randomly assigned to treatment groups. After the exclusion of 1 patient because of a diagnosis of intestinal tuberculosis, 248 patients (mean [SD] age, 60.2 [11.4] years; 153 men [61.7%]) were included in the analyses. The median (IQR) time to first defecation was 76.4 (67.6-96.8) hours in the EA group and 90.0 (73.6-100.3) hours in the SA group (mean difference, -8.76; 95% CI, -15.80 to -1.73; P = .003). In the EA group compared with the SA group, the time to first flatus (median [IQR], 44.3 [37.0-58.2] hours vs 58.9 [48.2-67.4] hours; P < .001) and the tolerability of semiliquid diet (median [IQR], 105.8 [87.0-120.3] hours vs 116.5 [92.0-137.0] hours; P = .01) and solid food (median [IQR], 181.8 [149.5-211.4] hours vs 190.3 [165.0-228.5] hours; P = .01) were significantly decreased. Prolonged POI occurred in 13 of 125 patients (10%) in the EA group vs 25 of 123 patients (20%) in the SA group (risk ratio [RR], 0.51; 95% CI, 0.27-0.95; P = .03). Other secondary outcomes were not different between groups. There were no severe adverse events. Conclusions and Relevance: Results of this randomized clinical trial demonstrated that in patients undergoing laparoscopic surgery for colorectal cancer with the ERAS protocol, EA shortened the duration of POI and decreased the risk for prolonged POI compared with SA. EA may be considered as an adjunct to the ERAS protocol to promote gastrointestinal function recovery and prevent prolonged POI after surgery.

OBJECTIVES: In this study we aimed to assess the clinicopathological characteristics and long-term prognosis of patients with nonalcoholic fatty liver disease (NAFLD) having distinct steatosis distribution patterns. METHODS: Clinicopathological data of 238 individuals with biopsy-confirmed NAFLD were collected. Nonalcoholic steatohepatitis-clinical research network (NASH-CRN) and steatosis, activity and fibrosis (SAF)/fatty liver inhibition of progression (FLIP) algorithm were used. Cumulative incidence of liver-related events (LREs) was compared by Kaplan-Meier analysis. Univariate and multivariate logistic regression analyses were used to identify independent predictors for steatosis distribution. RESULTS: Eligible patients were categorized into three groups based on their steatosis distribution, including azonal steatosis (AS) (62 [26.1%]), perivenular steatosis (PVS) (147 [61.8%]), and the pan-acinar steatosis (PAS) groups (29 [12.1%]). There were significantly higher ballooning grade and disease activity (P < 0.05), more severe fibrosis (P < 0.001), and a higher cumulative incidence of LREs (hazard ratio [HR] 8.0, 95% confidence interval [CI] 2.34-27.35, P < 0.0001) in the AS group than in the PVS and PAS groups after a median of 3.6-year follow-up. Multivariate logistic regression analysis revealed age (odds ratio [OR] 1.11, 95% CI 1.06-1.16, P < 0.001) might be independently associated with AS distribution, and PNPLA3 rs738409 CG/GG genotype (OR 3.36, 95% CI 0.98-11.47, P = 0.053) might also play a role. CONCLUSIONS: AS is associated with more severe disease activity and fibrosis stage in NAFLD, and predisposes toward poor prognosis. Age might be an independent predictor for AS in NAFLD, while PNPLA3 rs738409 CG/GG genotype might also play a role.

OBJECTIVE: To investigate chronic hepatitis B (CHB) patients infected with the antiviral-resistant rtA181 mutation hepatitis B virus (HBV) who have been unresponsive to general therapy to determine the effects of individualized therapy. METHODS: Fifty-four patients with confirmed rtA181 mutation and who experienced virological breakthrough during nucleus(t)ide analogue (NUC) treatment were enrolled in this prospective cohort study. Their serum levels of HBV DNA, hepatitis B surface antigen (HBsAg), and alanine transaminase (ALT) were tested. Each patient was genotyped by pyrosequencing for 10 mutation sites in the HBV P gene that have been previously correlated to NUC efficacy. Each patient's antiviral therapy and response history was analyzed in regard to their particular mutation pattern. The serological index was determined for carriers of the rtA181T/V mutation. The secondary individualized treatment included adding/switching to entecavir (ETV; group A) or adding telbivudine (LdT; group B) upon confirmation of drug resistance. Effect of individualized treatment was analyzed by T test and Mann-Whitney U test for continuous variables with normal or skewed distributions, respectively. Categorical variables were analyzed by the Chi-squared ( x² ) or Fisher's exact tests. RESULTS: The rtA181T mutation was found in 64.8% (35/54) of patients with rtA181 mutation HBV. The most frequent previously administered medications were adefovir dipivoxil (ADV) and lamivudine (LAM). Multi-site rtA181 mutations occurred more frequently in the patients with multi-NUCs history (57.6%) than in those with single NUCs history (28.6%) (x²=4.342, P less than 0.05). Serum HBV DNA level at virological breakthrough was lower than that at baseline of the first antiviral treatment (5.66+/-1.01 vs. 6.75+/-0.81 log10 copies/ml; t=-4.210, P less than 0.01). The serum HBsAg level was higher in carriers of the rtA181T mutation than in carriers of the rtA181V mutation (3.80+/-0.45 vs. 3.46+/-0.60 log10 IU/ml; t=2.109, P less than 0.05). In patients with serum HBV DNA more than or equal to 6 log10 copies/ml at viral breakthrough, 100% (8/8) of patients in the secondary treatment group A and 75% (3/4) patients in the secondary treatment group B exhibited virological response at week 24 after intervention. Undetectable HBV DNA was achieved in three patients of group A and one patient of group B. In patients with serum HBV DNA less than 6 log10 copies/ml at viral breakthrough, 100% (14/14) of patients in group A and 71.4% (5/7) of patients in group B exhibited biological response at week 24 after intervention. The serum HBV DNA level decreased to undetectable levels in 12 patients of group A and four patients of group B. CONCLUSION: The rtA181 mutation pattern correlates with previous antiviral therapy response. In addition, multi-site rtA181 mutations occur more frequently in patients with a history of multi-NUCs therapy. Adding or switching rtA181 carriers to ETV produces a more robust virological suppression than adding LdT.

OBJECTIVE: To evaluate the clinical effect of acupuncture for the improvements in various dyspeptic symptoms of postprandial distress syndrome. METHODS: The secondary analysis on the data of a multi-center randomized controlled trial (RCT) was conducted. 278 patients with postprandial distress syndrome were randomized into an acupuncture group (138 cases) and a sham-acupuncture group (140 cases). In the acupuncture group, acupuncture was applied to Baihui (GV 20), Danzhong (CV 17), Zhongwan (CV 12), Qihai (CV 6), Neiguan (PC 6), Zusanli (ST 36), etc. In the sham-acupuncture group, 6 sites, neither located on meridians nor belonged to meridian acupoints, were selected and punctured shallowly. The duration of treatment was 20 min each time, 3 times a week, for 4 weeks totally in the two groups. The follow-up visit lasted for 12 weeks. The scores of dyspeptic symptoms were compared between the two groups before treatment, during treatment (in week 1, 2, 3 and 4) and during follow-up (in week 8, 12 and 16) separately. RESULTS: Besides the scores of early satiety and vomiting in the sham-acupuncture group in week 1, the scores of the other dyspepsia symptoms during treatment and follow-up were all reduced in the two groups as compared with those before treatment (P<0.05). In week 2 and 3, the score of early satiety in the acupuncture group was lower than that in the sham-acupuncture group (P<0.05). In week 3, the scores of postprandial fullness, upper abdominal bloating and belching in the acupuncture group were lower than those in the sham-acupuncture group (P<0.05). In week 4 and during follow-up, the scores of postprandial fullness, early satiety, upper abdominal bloating and belching in the acupuncture group were all lower than those in the sham-acupuncture group (P<0.05). CONCLUSION: Acupuncture remarkably relieves postprandial fullness, early satiety, upper abdominal bloating and belching in patients with postprandial distress syndrome.

OBJECTIVE: To verify the clinical effect of acupuncture on knee osteoarthritis (KOA). METHODS: Forty-two patients with KOA were randomly divided into an acupuncture group (21 cases, 1 case dropped off) and a sham acupuncture group (21 cases, 1 case dropped off). The patients in the acupuncture group were treated with routine acupuncture at 5-6 local acupoints [Dubi (ST 35), Neixiyan (EX-LE 4), Heding (EX-LE 2), Yinlingquan (SP 9), Xuehai (SP 10), Zusanli (ST 36), etc.] and 3-4 distal acupoints [Fengshi (GB 31), Waiqiu (GB 36), Xuanzhong (GB 39), Zulinqi (GB 41), etc.]. The patients in the sham acupuncture group were treated with shallow needling technique at non-acupoint. The needles were retained for 30 min in both groups. All the treatment was given three times a week for 8 weeks. Knee injury and osteoarthritis outcome score (KOOS) were recorded before and after treatment and 18-week follow-up. RESULTS: Compared before treatment, the scores of 5 dimensions of KOOS [pain, symptoms (except pain), daily activities, sports and entertainment, and quality of life] were increased after treatment and during follow-up in the two groups (P<0.05), and the scores of pain and daily activities in the acupuncture group were higher than those in the sham acupuncture group (P<0.05). CONCLUSION: Acupuncture can reduce the pain symptoms and improve daily activities in patients with KOA.

OBJECTIVE: To assess the efficacy of intensive acupuncture (3 times weekly for 8 weeks) versus sham acupuncture for knee osteoarthritis (OA). METHODS: In this multicenter, randomized, sham-controlled trial, patients with knee OA were randomly assigned to receive electroacupuncture (EA), manual acupuncture (MA), or sham acupuncture (SA) 3 times weekly for 8 weeks. Participants, outcome assessors, and statisticians were blinded with regard to treatment group assignment. The primary outcome measure was response rate, which is the proportion of participants who simultaneously achieved minimal clinically important improvement in pain and function by week 8. The primary analysis was conducted using a Z test for proportions in the modified intent-to-treat population, which included all randomized participants who had ≥1 post-baseline measurement. RESULTS: Of the 480 participants recruited in the trial, 442 were evaluated for efficacy. The response rates at week 8 were 60.3% (91 of 151), 58.6% (85 of 145), and 47.3% (69 of 146) in the EA, MA, and SA groups, respectively. The between-group differences were 13.0% (97.5% confidence interval [97.5% CI] 0.2%, 25.9%; P = 0.0234) for EA versus SA and 11.3% (97.5% CI -1.6%, 24.4%; P = 0.0507) for MA versus SA. The response rates in the EA and MA groups were both significantly higher than those in the SA group at weeks 16 and 26. CONCLUSION: Among patients with knee OA, intensive EA resulted in less pain and better function at week 8, compared with SA, and these effects persisted though week 26. Intensive MA had no benefit for knee OA at week 8, although it showed benefits during follow-up.

BACKGROUND: Evidence for treating postprandial distress syndrome with acupuncture is limited. AIM: We aimed to evaluate the feasibility of verum acupuncture versus sham acupuncture in patients with postprandial distress syndrome. METHODS: A total of 42 eligible patients were randomly allocated to either verum acupuncture or sham acupuncture groups in a 1:1 ratio. Each patient received 12 sessions over 4 weeks. The primary outcome was the response rate based on the overall treatment effect (OTE) 4 weeks after randomization. Secondary outcomes included dyspepsia symptom severity and adverse events. RESULTS: In each group, 19 patients (91.5%) completed the study. Thirteen patients receiving verum acupuncture and seven patients receiving sham acupuncture were classified as responders according to OTE (61.9% vs 33.3%; rate difference 28.6%; p = 0.06). Dyspepsia symptom severity at the end of treatment also differed significantly between verum acupuncture and sham acupuncture groups (5.9 units vs 3.7 units; between-group difference 2.2 (95% CI, 0.2-4.2); p = 0.04). No serious adverse events occurred. CONCLUSION: Four weeks of acupuncture may represent a potential treatment for postprandial distress syndrome. The treatment protocol and outcome measures used in this trial were feasible. Since this was a pilot study, the efficacy of acupuncture still needs to be determined by a larger, adequately powered trial.

OBJECTIVE: We aimed to explore the feasibility of evaluating the comparative effectiveness and safety of electroacupuncture (EA) relative to manual acupuncture (MA) for the treatment of knee osteoarthritis (KOA). METHODS: A multicenter randomized controlled clinical trial was conducted in Beijing from September 2017 to January 2018. A total of 60 participants with KOA were randomly allocated to either EA (n = 30) or MA (n = 30) groups. Participants in the EA group were treated with EA at six to seven local traditional acupuncture points or ah shi points, and two to three distal points. Participants in the MA group had the same schedule as the EA group except that the electrical apparatus featured a working power indicator without actual current output, constituting a sham EA procedure, in order to blind participants. Both groups received 24 sessions over 8 weeks. The primary outcome was response rate, defined as a change of ⩾50% from baseline in the total scores of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) after 8 weeks. Secondary outcomes included pain, stiffness, function, quality of life, and acupuncture-related adverse events (AEs) at 4 and 8 weeks. RESULTS: Of 60 participants randomized, 53 (88%) completed the study. Response rates were 43% for the EA group and 30% for the MA group by the intention-to-treat analysis. Although significant differences were observed in WOMAC pain, stiffness, and function scores within both groups, between-group differences at 8 weeks did not reach statistical significance (odds ratio = 1.75 (95% confidence interval = 0.593-5.162)). Rates of AEs were low and similarly distributed between groups. CONCLUSION: Both EA and MA interventions in KOA were feasible and appeared safe. Whether or not EA may have a stronger impact on pain and function requires further evaluation through larger, adequately powered, randomized controlled trials. TRIAL REGISTRATION NUMBER: NCT03274713.

Background: Astragali radix is prone to be contaminated by various mycotoxins, leading to unpredictable threats on the quality and safety of Astragali radix and the health of the consumers. Therefore, the determination of multimycotoxins is imperative. Objective: To develop an efficient, sensitive, fast, and multianalyte method for detecting multimycotoxins in Astragali radix. Methods: A selective dilute-and-shoot pretreatment procedure based ultra-performance LC-tandem MS (UPLC-MS/MS) method was developed for sensitive determination of multimycotoxins in Astragali radix, including aflatoxin (AF) B1, B2, G1, G2, and ochratoxin A. The five mycotoxins were extracted by the dilute-and-shoot pretreatment procedure followed by UPLC-MS/MS detection. Types of sample extraction solvent, mobile-phase compositions and MS/MS parameters, and dilute-and-shoot conditions were optimized. Results: The optimized chromatographic and mass spectrometric conditions allowed the separation and detection of the five mycotoxins within 5 min. The validated UPLC-MS/MS method exhibited good sensitivity with LOD and LOQ lower than 0.2 and 0.5 µg/kg, respectively. RSD values for method precision were lower than 9%. Recoveries obtained were between 90.87 and 108.44% for all the analytes with RSDs of 3.96-8.03%. The developed method was applied for the detection of the 5 mycotoxins in 18 batches of Astragali radix with good determination performance and no matrix interferences. Two samples collected from Shanxi province and Neimenggu Autonomous Region in China were positive for AFB1 at 3.24 and 2.69 µg/kg, respectively. Conclusions: The dilute-and-shoot procedure allowed for the extraction of the mycotoxins with advantages of simple pretreatment, small extraction time, high selectivity and accuracy, as well as being cost effective and easy to operate without any clean-up steps. Highlights: This is the first report on dilute-and-shoot approach for mycotoxins extraction and detection in Chinese medicinal material matrixes.

OBJECTIVE: Patients with major depressive disorder (MDD) may experience a series of emotional and mental problems accompanied by characteristic clinical symptoms. Depressive patients often have emotional recognition disorders, but the reasons remain unclear. Though a great many functional abnormalities have been observed in the brains of depressed patients, such abnormalities are not often related to clinical symptoms. Currently in Traditional Chinese Medicine (TCM), syndrome differentiation for the MDD mainly consists of excess pattern (EP), and deficiency pattern (DP). EP and DP emphasize balance-regulation thought processes, and are widely used in diagnosis of diseases including depression, anxiety, insomnia, and other emotional disorders. We hope that syndrome differentiation in TCM can combine clinical symptoms and brain function more effectively. The present study investigated altered patterns and different association of brain activation in MDD patients with EP and DP during a facial emotion discrimination task with fMRI. METHODS: A total of 45 patients (20 with EP and 25 with DP) and 18 normal controls participated in this study. Whole-brain functional scans were collected for each subject. Different patterns of brain activation and association during the facial emotion discrimination task were analyzed statistically. RESULTS: Comparing all the MDD patients with the normal controls, there were no significant differences for sad vs. neutral condition or for happy vs. neutral condition (corrected p > 0.05). One-way ANCOVA showed significant differences in the left inferior frontal gyrus, the left insula, and the left caudate for sad vs. neutral condition across the DP, EP and NC groups (corrected p < 0.05). The whole brain activation comparison for sad vs. neutral condition between the EP MDD subtype and the DP MDD subtype further verified these differences in the left insula and left inferior frontal gyrus, discovering that these regions showed increased activation in EP MDD subtype compared with the DP MDD subtype (corrected p < 0.05). There were no significant differences in brain activation between each MDD subtype and the normal controls. CONCLUSION: Disparities in sad face processing exist between MDD patients with different TCM syndrome types, suggesting that TCM syndrome differentiation may provide a biological basis for negativity bias in depression, and may determine both symptom formation and social dysfunction.

OBJECTIVE: To observe the effect of the small needle knife through the Zusanli(ST 36) on behavior and hippocampal expression of NLRP3 and IL-1ß in myalgia comorbid depressed rats. METHODS: The rat models of myalgia comorbid depression were prepared by intraperitoneal injection of acute reserpine. Twenty-four SD male rats were randomly divided into control group, model group, small needle knife group and amitriptyline group, 6 rats in each group. The open field behavior and mechanical pain threshold of each group were detected. The thermal pain threshold was detected by intelligent hot plate test. The expression of NLRP3 and IL-1ß in hippocampus of rats was detected by Western blotting. RESULTS: Compared with the model group, the mechanical pain threshold of the foot was significantly improved in the small needle knife group (P<0.01). Compared with the amitriptyline group, the small needle knife stimulation of Zusanli(ST 36) can significantly increase the thermal pain threshold in rats(P<0.05); in the comparison of the horizontal movement distance and the number of crossings in the open field behavioral rats, the total distance of the open field activity of the small needle knife group was significantly increased(P<0.05). Compared with the model group, the number of crossings in the small needle knife group had no statistically significant difference (P>0.05). The expressions of NLRP3 and IL-1ß in the hippocampus of the model group were significantly increased(P<0.05), and the expression of IL-1ß in the small needle knife group was significantly decreased (P<0.05). The stimulation of small needle knife at Zusanli(ST 36) could inhibit the expression of NLRP3 in hippocampus of rats. However, there was no statistically significant difference compared with the model group (P>0.05). CONCLUSIONS: Small needle knife can improve the pathological state of myalgia comorbid depression caused by reserpine in rats. The mechanism may be related to the inhibition of NLRP3 inflammasome and IL-1ß expression in central hippocampus.

BACKGROUND: Postprandial distress syndrome (PDS) has a considerable impact on quality of life. Our previous pilot trial suggested that acupuncture might be a potential treatment option for PDS. We will conduct this large trial to determine the efficacy of acupuncture versus sham acupuncture for PDS. METHODS/DESIGN: A total of 280 eligible patients who meet the Rome IV criteria for PDS will be randomly allocated to either the acupuncture group or the sham acupuncture group. Each patient will receive 12 sessions over four weeks. The primary outcomes will be the response rate of overall treatment effect (OTE) and the elimination rate of all three cardinal symptoms (postprandial fullness, upper abdominal bloating, and early satiation) at four weeks after randomization. Secondary outcomes will include assessments of the severity of dyspepsia symptoms and disease-specific quality of life at weeks 4, 8, and 16 after randomization. All patients who receive randomization will be included in the intent-to-treat analysis. DISCUSSION: The finding of this trial will provide high-quality evidence on the efficacy of acupuncture for treatment of PDS. Results of this research will be published in peer-reviewed journals. TRIAL REGISTRATION: ISRCTN Registry, ISRCTN12511434 . Registered on 31 March 2017.

RESUMEN
BACKGROUND: Knee osteoarthritis (KOA) is one of the most common musculoskeletal disorders. Although the available evidence for its efficacy is inconclusive, acupuncture is used as an alternative therapy for KOA. The aim of this trial is to determine the efficacy of electro-acupuncture and manual acupuncture versus sham acupuncture for KOA. METHODS/DESIGN: This is a study protocol for a randomised, three-arm, multicentre, clinical trial. A total of 480 patients with KOA will be randomly assigned to the electro-acupuncture group, the manual acupuncture group or the sham acupuncture group in a 1:1:1 ratio. All patients will receive 24 sessions over 8 weeks. Participants will complete the trial by visiting the research centre at week 26 for a follow-up assessment. The primary outcome is the success rate: the proportion of patients achieving a minimal clinically important improvement, which is defined as ≥2 points on the numerical rating scale and ≥6 points on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) function score at week 8 compared with baseline. Secondary outcomes include the numerical rating scale, WOMAC score, global patient assessment and quality of life at weeks 4, 8, 16 and 26 after randomisation. DISCUSSION: This trial may provide high-quality evidence for the efficacy of acupuncture in the treatment of KOA. The results of this study will be published in peer-reviewed journals. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03274713 . Registered on 20 November 2017.

OBJECTIVE: The objective of this study was to explore the relationship between increased plasma osteoprotegerin (OPG) levels and acute coronary syndrome (ACS). METHODS: Plasma OPG levels from 85 subjects undergoing coronary artery angiography in three different groups, including ACS (n=45), stable angia pectoris (SAP) (n=20) and normal coronary artery (NCA) (n=20), were detected by ELISA. Twenty-two ascending aorta specimens were surgically taken from 8 ACS, 7 SAP and 7 NCA patients, and OPG mRNA expression in the specimens was detected by RT-PCR. In addition, 10 coronary artery sections each were selected from autopsy archives for the presence of vulnerable atherosclerosis plaques (VP), stable plaques (SP) or no plaques (NP) and OPG protein expression in the sections was detected by immunohistochemistry. RESULTS: Plasma OPG concentrations in the ACS group were significantly higher than those in the SAP or NCA group.The levels of plasma OPG in the 1-, 2- and 3-vessel disease subgroups of ACS were increasingly higher (P < 0.05 or 0.01). Multiple logistic regression analyses revealed a significant independent relation between plasma OPG concentration and the presence of ACS (P = 0.032, odd ratio = 1.006).Ascending aorta specimens from the ACS group had a greater OPG mRNA expression than those from the NCA or SAP group (P < 0.01). Sections with VP had a markedly higher OPG expression than sections with SP or NP (P < 0.05 and P < 0.01, respectively). CONCLUSIONS: Increased plasma osteoprotegerin levels are associated with the presence and severity of acute coronary syndrome.

OBJECTIVE: To investigate the association of thrombin activatable fibrinolysis inhibitor (TAFI) and its encoding gene CPB2 polymorphism in patients with coronary heart disease (CHD). METHODS: The CPB2 gene polymorphisms of Thr325Ile and Thr147Ala were analyzed with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in patients of acute myocardial infarction (n=100), acute angina pectoris (n=110) and a control group (n=190). The antigen (Ag) and activity (Act) of the TAFI were determined by sandwich enzyme link immunosorbent assay specific for human TAFI and chromogenic assay for activated human TAFI in plasma, respectively. The relationship between Thr325Ile and Thr147Ala gene polymorphism and TAFI Ag and Act were also analyzed. RESULTS: Plasma TAFI Act and TAFI Ag in acute myocardial infarction group and acute angina pectoris group (CHD patients group) were both significantly higher than those of the control group. The genotype frequencies of Thr325Ile (C1040T) and Thr147Ala (G505A) were as the following: C1040C (Thr325Thr) 67 (31.9%) and 64 (33.6%); C1040T (Thr325Ile) 109 (51.9%) and 92 (48.4%); T1040T (Ile325Ile) 34 (16.2%) and 34(17.8%); G505G (Ala147 Ala) 75 (35.7%) and 72 (37.8%); G505A(Thr147Ala) 112 (53.3%) and 96 (50.5%); A505A(Thr147Thr)23 (10.9%) and 22 (11.7%), in the CHD patients and control respectively. Chi-square analysis showed no significant difference in the Thr325Ile and Thr147Ala polymorphism distributions (P > 0.05). In addition, at the 325 position, the TAFI antigen of the Thr325Thr was higher than that of the other genotypes (Thr325Ile and Ile325Ile, P < 0.05). There was no statistical significance between the TAFI antigen of the Thr325Ile and Ile325Ile (P > 0.05). No significant correlation was found between the TAFI Act and the Thr325Ile polymorphism. At the position 147, significant correlation between the polymorphism of the Thr147Ala and TAFI Ag and Act was not found. CONCLUSION: TAFI plays an important role in anti-fibrinolysis. It might be a risk factor for acute myocardial infarction and acute angina pectoris. The Thr325Ile polymorphism had obvious effect on TAFI antigen levels, but the Thr325Ile and Thr147Ala polymorphism had no association with coronary heart disease.

Major depressive disorder (MDD) is a highly prevalent psychiatric disorder that has been ranked as the 4th leading cause of disability worldwide. Past clinical and laboratory evidence has confirmed that abnormalities of the hypothalamic-pituitary-adrenal (HPA)-axis are involved in MDD development. In this study, we took advantage of corticosterone treatment of PC12 cells as a model to identify genes regulated by HPA-axis hormones. Next-generation RNA-Seq technology was utilized to explore genome-wide differentially expressed gene profiles between control and corticosterone treated PC12 cells. 1,274 genes with at least two-fold expression level change were identified. Gene ontology analysis showed that the top enriched biological processes included response to glucocorticoid signaling, apoptosis, cell division/DNA replication, and neuron projection/axon guidance, highly consistent with phenotypes of PC12 cells treated with corticosterone. Taken together, RNA-seq data is reliable and comprehensive, thus providing a valuable resource for understanding underlying mechanisms of glucocorticoid-induced neuron malfunction.
