Meta-analysis of acupuncture and moxibustion for the therapeutic effect on postoperative gastrointestinal dysfunction of gastric cancer / 中国针灸

OBJECTIVE@#To systematically review the therapeutic effect of acupuncture and moxibustion on postoperative gastrointestinal dysfunction (GID) of gastric cancer with meta-analysis.@*METHODS@#The articles of randomized controlled trials (RCTs) of acupuncture and moxibustion treatment for postoperative GID of gastric cancer were retrieved from the following databases from the time of database establishment to December 31, 2020, including PubMed, EMbase, Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Infrastructure (CNKI), Wanfang database, VIP database and China Biomedical Literature Database (SinoMed). RevMan5.3 software was used for meta-analysis. Using Stata16.0 software, sensitivity analysis and publication bias test were performed.@*RESULTS@#A total of 16 RCTs were included finally, including 1 360 patients, of which, there were 681 cases in the intervention group and 679 cases in the control group. Meta-analysis results showed that acupuncture and moxibustion shortened the time of first flatus (P<0.000 01, MD =-14.52, 95%CI = [-17.31, -11.74]), the time of first bowel sound (P<0.000 01, MD =-10.50, 95%CI =[-13.99, -7.01]) and the time of first defecation (P<0.000 1, MD =-13.79, 95%CI =[-20.09, -7.50]). Meanwhile, acupuncture and moxibustion shortened the time of the first food intake (P<0.000 1, MD =-3.23, 95%CI = [-3.45, -3.00]) and the hospital stay (P<0.000 01, MD =-1.94, 95%CI =[-2.20, -1.69]) after gastric cancer operation, and reduced the incidences of postoperative adverse reactions, i.e. nausea and vomiting (P =0.000 3, RR =0.43, 95%CI =[0.28, 0.68]) and abdominal distention (P =0.000 5, RR =0.41, 95%CI =[0.25, 0.68]).@*CONCLUSION@#Acupuncture and moxibustion can promote the recovery of postoperative gastrointestinal function in the patients with gastric cancer. But, for the comparison among different measures of acupuncture and moxibustion intervention, it needs more high-quality trials for a further verification.

WU Xu's experience of sequential therapy for peripheral facial paralysis / 中国针灸

The paper introduces professor WU Xu 's experience of sequential therapy for peripheral facial paralysis. The sequential therapy refers to a staging treatment, but not rigidly adheres to it. With this therapy, the acupuncture- moxibustion regimen is modified flexibly in line with the specific symptoms of illness. At the acute phase of peripheral facial paralysis, warm acupuncture at Wangu (GB 12) is predominated and electroacupuncture is not recommended at the acupoints on the face. At the recovery phase, warm acupuncture at Zusanli (ST 36) is the main therapy and electroacupuncture is applied to the acupoints on the face appropriately. Besides, for the intractable case, the tapping technique with plum-blossom needle or skin needle should be combined and exerted in the local affected region. At the sequelae phase, in order to shorten the duration of illness, depending on the different types of facial paralysis, i.e. stiffness type, spasmodic type and flaccid type, the corresponding needling techniques are provided, i.e. bloodletting and moxibustion, strong stimulation with contralateral acupuncture and the technique for promoting the governor vessel and warming up yang.

Ultrasound-guided electroacupuncture at suprahyoid muscle group for pharyngeal dysphagia after stroke: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the effect among ultrasound-guided electroacupuncture (EA) at suprahyoid muscle group, conventional acupuncture and conventional EA at suprahyoid muscle group on pharyngeal dysphagia after stroke, and to explore its biomechanical mechanism.@*METHODS@#A total of 120 patients with pharyngeal dysphagia after stroke were randomly divided into an observation group, a control-1 group and a control-2 group, 40 cases in each group. The patients in the observation group were treated with ultrasound-guided EA at suprahyoid muscle group; the patients in the control-1 group were treated with EA at Lianquan (CV 23), Wangu (GB 12) and Fengchi (GB 20), etc.; the patients in the control-2 group were treated with EA at suprahyoid muscle group according to anatomical location. The EA in the three groups were discontinuous wave, with frequency of 5 Hz and current intensity of 1 mA. The EA was given for 30 minutes, once a day, 6 times were taken as a course of treatment, and 4 courses of treatment were provided. The video floroscopic swallowing study (VFSS) was performed before and after treatment. The Rosenbek penetration-aspiration scale (PAS) score, the forward and upward movement distance of hyoid bone and thyroid cartilage, Ichiro Fujima ingestion-swallowing function score were recorded in the three groups, and the incidences of subcutaneous hematoma were recorded after treatment.@*RESULTS@#Compared before treatment, the PAS scores were reduced and the Ichiro Fujima ingestion-swallowing function scores were increased after treatment in the three groups (P<0.05); the PAS scores in the observation group were lower than those in the control-1 group and the control-2 group, and the Ichiro Fujima ingestion-swallowing function scores in the observation group were higher than those in the control-1 group and the control-2 group (P<0.05). After treatment, the forward and upward movement distance of hyoid bone and thyroid cartilage in the observation group and the control-2 group was increased (P<0.05), and the forward and upward movement distance of hyoid bone was increased in the control-1 group (P<0.05); the forward and upward movement distance of hyoid bone and thyroid cartilage in the observation group was longer than that in the control-1 group and the control-2 group (P<0.05). The incidence of subcutaneous hematoma in the observation group was 0% (0/40), which was lower than 20.0% (8/40) in the control-1 group and 47.5% (19/40) in the control-2 group (P<0.05).@*CONCLUSION@#Ultrasound-guided EA at suprahyoid muscle group could improve the swallowing function in patients with pharyngeal dysphagia after stroke by increasing the motion of hyoid laryngeal complex. Its effect and safety are better than conventional acupuncture and conventional EA at suprahyoid muscle group.

[Cloning and functional characterization of farnesyl diphosphate synthase in Senecio scandens].

As a secondary metabolite, sesquiterpenes are not only have important functions in plant defense and signaling, but also play potential roles in basic materials for pharmaceuticals, cosmetic and flavor. As a traditional Chinese herbal medicine, Senecio scandens exhibits effects of anti-inflammatory and immunosuppressive, as well as invigorating the blood and removing extravasated blood. Over 600 sesquiterpenes with diverse structures were isolated from S. scandens and related species in the same genus. To characterize sesquiterpenes synthesis, two FPS genes(SsFPS1 and SsFPS2) were identified in S. scandens through transcriptomic analysis. Bioinformatic analysis showed that both SsFPSs have conserved motifs for FPS function. Both SsFPSs exhibited constitutive gene expression in S. scandens tissues and SsFPS2 accumulated higher transcript in leaves and roots than SsFPS1. Meanwhile consistent with constitutive sesquiterpene accumulation in S.scandens tissues, most of these sesquiterpenes were detected in leaves and roots more than stems and flowers. Recombinant expression through Escherichia coli metabolic engineering, SsFPS1 or SsFPS2 was co-transformed with ZmTPS11(maize ß-macrocarpene synthase) into BL21 competent cells. The results showed that the content of ß-macrocarpene was increased by co-transformation with SsFPSs. It is demonstrated that SsFPS1 and SsFPS2 catalyzed E,E-FPP formation and provided FPP precursor for downstream sesquiterpene synthases. Characterization of SsFPSs provided the foundation for the exploration of biosynthesis of sesquiterpenoid with diverse structures and potential pharmaceutical values in S.scandens, and provide an important theoretical basis for the development of S. scandens abundant resources.

Right free-wall accessory pathway with branched atrial insertions: Clinical, electrocardiographic, and electrophysiological characteristics.

BACKGROUND: Right free-wall (RFW) accessory pathway (AP) with branched atrial insertions is a rare, underrecognized AP that may be associated with initial ablation failure. OBJECTIVE: The purpose of this study was to investigate the clinical and electrophysiological characteristics of this AP. METHODS: From January 2011 to March 2018, 10 patients identified with branched RFW-AP were enrolled in this study, and 30 consecutive patients with conventional RFW-APs served as control group. Right atrium (RA) was activation-mapped and 3-dimensionally reconstructed during AP-mediated orthodromic tachycardia or right ventricular pacing. Atrial insertions were defined as the earliest breakout sites, and their relationship with the tricuspid annulus (TA) were described and analyzed. RESULTS: An average of 3 separate atrial insertions on the atrial side were documented among these 10 cases (5 female and 5 male; mean age 38.0 ± 13.9 years). All atrial insertions were away from the TA. The nearest atrial insertions averaged 15.9 ± 3.4 mm away from the TA, and the farthest atrial insertions were 22.6 ± 5.7 mm away from the TA. Anterograde and retrograde AP conduction remained unaffected after ablation of the first earliest breakout site but were eliminated by ablating all insertions after an average of 2.5 (range 2-2.5) remaps, 3 sites of ablation (range 2.5-4.5), 21 (range 15.5-37.8) radiofrequency applications, and 659.5 (range 464.3-1144.3) seconds of radiofrequency ablation duration. After 12-month follow-up, no patients reported AP conduction recovery or recurrent tachycardia. CONCLUSION: RFW-AP with branched atrial insertions is an atypical AP variant and featured by >1 distinct atrial insertions on atrial side. Stepwise ablation rather than single focal ablation is required to eliminate all retrograde conduction.

The sensitization phenomena and regularity of Hegu (LI 4) based on bibliometrics / 中国针灸

The sensitization phenomena and regularities of Hegu (LI 4) were preliminarily explored. The relevant literature regarding Hegu (LI 4) sensitization were collected by computer retrieval at Cochrane Library, Pubmed, Embase (OvidSP), China Journal Full Text Database (CNKI), China Biomedical Literature Database (CBM), VIP and Wanfang (WF) databases as well as manual searching, and a modern literature database of Hegu (LI 4) sensitization was established. The information of disease type, sensitization type, detection method and index were collected. Frequency statistics method was used for analysis. As a result, 47 literatures were included, of which heat sensitivity was the most common type of sensitization, and diseases of liver and gallbladder, limb meridians, lung system, and spleen-stomach system were the most common types of diseases. The detection method of sensitization was various, among them, potassium ion introduction method and hot-water tail-flick method were mainly used for pain sensitivity, while acupoint resistance measuring instrument was mainly used for electric sensitivity, while thermal infrared imager was mainly used for heat sensitivity, while infrared spectrometric analyzer was mainly used for light sensitivity, while pressing pain measuring instrument was used for pressing sensitivity. Detection index was different, pain sensitivity detected pain threshold, electric sensitivity mainly detected acupoint resistance, heat sensitivity mainly detected temperature, light sensitivity detected average sharpness and average energy of infrared radiation, pressing sensitivity detected pressing-pain threshold. In conclusion, the regularities of sensitization of Hegu (LI 4) were preliminarily summarized, which involved five sensitization types: heat sensitivity, electric sensitivity, pain sensitivity, pressing sensitivity and light sensitivity. The sensitization of Hegu (LI 4) was commonly seen in facial paralysis, bronchial asthma, allergic rhinitis, tinnitus, ulcerative colitis. The temperature, pain threshold, pressing-pain threshold, average sharpness and average energy of infrared radiation of Hegu (LI 4) in pathological condition were lower than those in healthy subjects, and the resistance value was higher than that of healthy subjects.

Effects of Shenshuaikang Enema Liquid on the Wnt/β-catenin pathway for inhibiting the hypoxia reoxygenation injury in HK-2 cells / 中成药

AIM To investigate the protective effect of serum containing Shenshuaikang Enema Liquid (Rhei Radix et Rhizoma,Salviae miltiorrhizae Radix et Rhizoma,Carthami Flos,Astragali Radix) on HK-2 cells injured by hypoxia/reoxygenation (H/R) and its effect on Wnt/β-catenin pathway.MEHTODS Six New Zealand white rabbits randomly divided into control group,Shenshuaikang high dose group and PBS group (n =2) were treated accordingly for serum collection after 3 days' enema.The HK-2 cells injured by hypoxia/reoxygenation were then administered with serum of rabbits from the control group,PBS group,Shenshuaikang groups (high dose,middle dose and low dose groups due to the differently diluted concentrations) respectively.The H/R damage was determined by ROS fluorescence probe,the cellular damage/apoptosis were analyzed by CFSE/PI method and flow cytometry combined with Annexin V-FITC/PI,and the investigation on effects of drugs on expression of Wnt4 mRNA and β-catenin mRNA were accomplished by fluorescence quantitative PCR.RESULTS The fluorescence intensity of intracellular ROS expression was significantly increased after modeling.CFSE/PI double staining showed that the variant Shenshuaikang dose groups displayed obvious proportional mortality superiority to either the control group or PBS group,and the high dose group achieved the lowest mortality.Annexin V-FITC/PI and flow cytometry showed that,at 12 h,compared with the control group (45.6 ± 2.2)％ and PBS group (41.6 ±0.7) ％,Shenshuaikang groups [low dose group (14.8 ± 0.3) ％,middle dose group (10.3 ± 0.6) ％,high dose group (12.9 ± 0.9)％] obviously inhibited apoptosis/death.Shenshuaikang Enema Liquid medicated serum demonstrated its significant effect on the increase of the Wnt4 mRNA expression and a dual-directional regulation on the expression of β-caterin mRNA by quantitative PCR (P ＜ 0.05).CONCLUSION Inhibition of the apoptosis/death of HK-2 cells with hypoxia/reoxygenation injury due to the serum containing Shenshuaikang Enema Liquid suggests the agent's influence on the activation of Wnt/β-catenin pathway.

[Effect of a chemical primer on the bond strength of a zirconia ceramic with self-adhesive resin cement].

OBJECTIVE: To evaluate the bond strength and durability of a self-adhesive resin cement with a zirconia ceramic pretreated by a zirconia primer. METHODS: Zirconia ceramic (Vita Inceram YZ) plates with a thickness of 2.5 mm were fired, polished, and then cleaned. Half of the polished ceramic plates were sandblasted with 50 µm alumina particles at 0.3 MPa for 20 s. The surface compound weight ratios were measured via X-ray fluorescence microscopy. The polished and sandblasted ceramic plates were directly bonded with self-adhesive resin cement (Biscem) or were pretreated by a zirconia primer (Z Primer Plus) before bonding with Biscem. The specimens of each test group were divided into two subgroups (n=10) and subjected to the shear test after 0 and 10,000 thermal cycles. The data were analyzed via three-way ANOVA. RESULTS: After air abrasion, 8.27% weight ratio of alumina attached to the zirconia surface. Compared with air abrasion, primer treatment more significantly improved the primary resin bond strength of the zirconia ceramic. The primary resin bond strength of the zirconia ceramic with no primer treatment was not affected by thermocycling (P>0.05). However, the primary resin bond strength of the zirconia ceramic with primer treatment was significantly decreased by thermocycling (P<0.05). CONCLUSION: Primer treatment can improve the primary resin bond strengths of zirconia ceramics. However, the bond interface of the primer is not stable and rapidly degraded during thermocycling.

Clinical Study of Acupuncture Intervention in Muscle, Bone and Joint Pain Caused by Aromatase Inhibitors in the Treatment of Breast Cancer / 上海针灸杂志

Objective To investigate the clinical efficacy of acupuncture intervention in muscle, bone and joint pain caused by aromatase inhibitors in the treatment of breast cancer. Method One hundred and forty breast cancer patients with aromatase inhibitors-caused muscle, bone and joint pain were randomly allocated to groups A, B, C and D, 35 cases each. group A received ear acupuncture plus the intravenous drip of zoledronic acid;group B, ear acupuncture alone;group C, the intravenous drip of zoledronic acid alone;group D, oral administration of calcium carbonate and vitamin D3 chewable tablets and alfacalcidol soft capsules. The Brief Pain Inventory score was observed in every group before and after treatment. Bone mineral densities of the lumbar vertebrae were compared between the groups before and after treatment. Result In groups a and B, there was a statistically significant difference in the pain interference score at three, six and twelve weeks of treatment and at six weeks after the end of treatment compared with before treatment (P0.05). Conclusion Ear acupuncture can significantly relieve muscle, bone and joint pain caused by aromatase inhibitors and the pain relief is not related to bone mineral density, but muscle, bone and joint pain recurs in the patients after the treatment is discontinued. Zoledronic acid can not relieve the pain. Ear acupuncture plus zoledronic acid is not more effective than ear acupunctura alone in relieving the pain.

Identification of metabolites of epiberberine in rat liver microsomes and its inhibiting effects on CYP2D6 / 中国中药杂志

Epiberberine, one of the most important isoquinoline alkaloid in Coptidis Rhizoma, possesses extensive pharmacological activities. In this paper, the liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to study phase I and phase II metabolites. A Thermo HPLC system (including Surveyor AS, Surveyor LC Pump, Surveyor PDA. USA) was used. The cocktail probe drugs method was imposed to determine the content change of metoprolol, dapsone, phenacetin, chlorzoxazone and tolbutamide simultaneously for evaluating the activity of CYP2D6, CYP3A4, CYP1A2, CYP2E1 and CYP2C9 under different concentrations of epiberberine in rat liver microsomes. The result showed that epiberberine may have phase I and phase II metabolism in the rat liver and two metabolites in phase I and three metabolites in phase II are identified in the temperature incubation system of in vitro liver microsomes. Epiberberine showed significant inhibition on CYP2D6 with IC50 value of 35.22 μmol L(-1), but had no obvious inhibiting effect on the activities of CYP3A4, CYP1A2, CYP2E1 and CYP2C9. The results indicated that epiberberine may be caused drug interactions based on CYP2D6 enzyme. This study aims to provide a reliable experimental basis for its further research and development of epiberberine.

Effect of comparability of Coptis chinensis and Scutellaria baicalensis on five sub-enzymatic activities of liver microsomes in rats / 中国中药杂志

To study the mechanism of metabolic interaction between Coptis chinensis and Scutellaria baicalensis. Rats were given C. chinensis and S. baicalensis for 7 days to produce hepatic microsomal enzyme. Cocktail probe substrate and liver microsome in vitro temperature incubation method were adopted. Meanwhile, the metabolic elimination percentages of the five probe substrates were detected with HPLC, in order to evaluate the effect of each administration group on the enzymatic activity of rat liver microsome CYP450. Compared with the blank group, C. chinensis obviously inhibited CYP2D6 and CYP1A2, and S. baicalensis remarkably inhibited CYP1A2, CYP2E1 and CYP2C9. The compatibility of C. chinensis and S. baicalensis with the ratio of 1:1 not only inhibited CYP1A2, but also remarkably activated CYP2D6 and CYP3A4. However, their activation effect disappeared under the ratio of 2: 1, and turned into the inhibitory effect on CYP1A2 and CYP2C9. The results showed that C. chinensis and S. baicalensis had an inhibitory effect on CYP450, but their compatibility with certain ratio resulted in double effects of activation and inhibition, which was related to their compatibility ratio. It is speculated that the inhibitory and inducing effects of C. chinensis and S. baicalensis on metabolic enzymes are among causes for their attenuation and synergistic effects.
