OBJECTIVES: To explore the effects of the combination of he-sea and front-mu points on the feeding compliance rate, the intra-abdominal pressure, the enteral nutrition tolerance score, the score of acute physiological and chronic health evaluation (APACHE)-Ⅱ and gastrointestinal function impairment grade in the patients with enteral nutrition feeding intolerance (ENFI) of critical illness and evaluate clinical effect on ENFI after acupuncture at the he-sea and front-mu points. METHODS: Seventy patients of ENFI were randomized into a control group and an observation group, 35 cases in each one. In the control group, the patients were treated with routine regimen combined with intestinal nutrition support. In the observation group, on the basis of the treatment as the control group, acupuncture was applied to Shangwan (CV13), Zhongwan (CV12), Xiawan (CV10), Qihai (CV6) and Guanyuan (CV4), as well as bila-teral Neiguan (PC6), Zusanli (ST36), Xiajuxu (ST39), Shangjuxu (ST37), Tianshu (ST25) and Daheng (SP15). Of those acupoints, ST25 and SP15 on the same side were attached to one pair of electrodes (20 Hz/100 Hz). Acupuncture was delivered once daily, 30 min each time and for consecutive 7 days. During treatment, the numbers of the cases up to the feeding standard were observed everyday to calculate the feeding compliance rate. The score of enteral nutrition tolerance, the intra-abdominal pressure, the score of APACHE-Ⅱ and the level of acute gastriointestinal injury(AGI) grading were recorded. RESULTS: After treatment, the enteral feeding compliance rate was increased in comparison with that before treatment in the two groups, and the rate in the observation group was higher than that of the control group (P<0.05) except that on the 2nd day. The score of the enteral nutrition tolerance, the intra-abdominal pressure, the score of APACHE-Ⅱ and the level of AGI were all reduced (P<0.05, P<0.01) when compared with those before treatment in the two groups, and these indicators in the observation group were lower (P<0.05) than those of the control group. CONCLUSIONS: Acupuncture at the he-sea and front-mu points relieves the conditions of ENFI, improves the feeding and the recovery of gastrointestinal function, and benefits the prognosis through increasing the amount of enteral nutrition in ENFI patients.

Kinetically and thermodynamically controlled one-pot growth of gold nanoshells with NIR-II absorption for multimodal imaging-guided photothermal therapy.

Since the successful clinical trial of AuroShell for photothermal therapy, there is currently intense interest in developing gold-based core-shell structures with near-infrared (NIR) absorption ranging from NIR-I (650-900 nm) to NIR-II (900-1700 nm). Here, we propose a seed-mediated successive growth approach to produce gold nanoshells on the surface of the nanoscale metal-organic framework (NMOF) of UiO-66-NH2 (UiO = the University of Oslo) in one pot. The key to this strategy is to modulate the proportion of the formaldehyde (reductant) and its regulator / oxidative product of formic acid to harness the particle nucleation and growth rate within the same system. The gold nanoshells propagate through a well-oriented and controllable diffusion growth pattern (points → facets → octahedron), which has not been identified. Most strikingly, the gold nanoshells prepared hereby exhibit an exceedingly broad and strong absorption in NIR-II with a peak beyond 1300 nm and outstanding photothermal conversion efficiency of 74.0%. Owing to such superior performance, these gold nanoshells show promising outcomes in photoacoustic (PA), computed tomography (CT), and photothermal imaging-guided photothermal therapy (PTT) for breast cancer, as demonstrated both in vitro and in vivo.

A comparative UHPLC-Q/TOF-MS-based metabolomics approach coupled with machine learning algorithms to differentiate Keemun black teas from narrow-geographic origins.

Geographic-label is a remarkable feature for Chinese tea products. In this study, the UHPLC-Q/TOF-MS-based metabolomics approach coupled with chemometrics was used to determine the five narrow-geographic origins of Keemun black tea. Thirty-nine differentiated compounds (VIP > 1) were identified, of which eight were quantified. Chemometric analysis revealed that the linear discriminant analysis (LDA) classification accuracy model is 91.7%, with 84.7% cross-validation accuracy. Three machine learning algorithms, namely feedforward neural network (FNN), random forest (RF) and support vector machine (SVM), were introduced to improve the recognition of narrow-geographic origins, the performances of the model were evaluated by confusion matrix, receiver operating characteristic curve (ROC) and area under the curve (AUC). The recognition of RF, SVM and FNN for Keemun black tea from five narrow-geographic origins were 87.5%, 94.44%, and 100%, respectively. Importantly, FNN exhibited an excellent classification effect with 100% accuracy. The results indicate that metabolomics fingerprints coupled with chemometrics can be used to authenticate the narrow-geographic origins of Keemun black teas.

[Research strategy thoughts about acupuncture-moxibustion treatment of chronic atrophic gastritis by suppressing apoptosis via circular RNA].

Chronic atrophic gastritis (CAG) is a common digestive disease in clinic. Previous experimental and clinical studies have shown that acupuncture has a positive effect for CAG. Apoptosis of gastric mucosal tissue has been shown to play an important role in the process of gastric atrophy and possibly further carcinogenesis in CAG, and the circular RNA (circRNA), a novel class of non-coding RNA, has been confirmed to play a regulatory role in the downstream pathway of apoptosis by many stu-dies. Accumulated findings of experimental studies showed that acupuncture and moxibustion interventions could suppress apoptosis of the cultured human gastric mucosal epithelial cells and lower apoptotic index of gastric mucosal cells in CAG rats. Therefore, circRNA is likely to mediate the inhibitory effect of acupuncture and moxibustion on apoptosis of gastric mucosal epithelial cells in CAG. In this paper, we systematically summarized 1) the regulation of circRNA on apoptosis, 2) the apoptosis and pathological mechanism of CAG, 3) the effect of acupuncture on apoptosis, and proposed that circRNA is highly likely to be involved in the positive effect of acupuncture and moxibustion interventions for CAG. It is recommended that researches should further reveal the scientific basis of acupuncture and moxibustion therapies in the treatment of CAG by exploring the role of related circRNAs and their downstream target proteins in the gastric mucosal tissues.

[Therapeutic effect on post-stroke spastic paralysis of upper extremity treated with combination of kinematic-acupuncture therapy and rehabilitation training].

OBJECTIVE: To compare the clinical therapeutic effect on post-stroke spastic paralysis of the upper extremity between the combination of kinematic-acupuncture therapy and rehabilitation training and the combined treatment of the conventional acupuncture with rehabilitation training. METHODS: A total of 60 patients of post-stroke spastic paralysis of the upper extremity at the non-acute stage were randomized into an observation group (30 cases) and a control group (30 cases, 1 case dropped off). On the base of the routine western medication and rehabilitation treatment, the kinematic-acupuncture therapy was added in the observation group and the conventional acupuncture was used in the control group. Baihui (GV 20), Dazhui (GV 14), Jiaji (EX-B 2) from T1 to T8, Tianzong (SI 11), Jianzhen (SI 9), Jianyu (LI 15) and Quyuan (SI 13) were selected in both groups. The treatment was given once daily and the treatment for 14 days was as one course. The one course of treatment was required in this research. Separately, before treatment and in 7 and 14 days of treatment, the score of simplified Fugl-Meyer scale of the upper extremity (FMA-UE), the grade of the modified Ashworth scale (MAS) and the score of the modified Barthel index scale (MBI) were compared between the two groups. RESULTS: Compared before treatment, in 7 and 14 days of treatment, FMA-UE score was increased obviously in either group (P<0.01). In 14 days of treatment, FMA-UE score in the observation group was higher than that in the control group (P<0.05). In 7 and 14 days of treatment, MAS grades of shoulder joint, elbow joint, wrist joint and metacarpophalangeal joint were all improved markedly in the two groups (P<0.05). Compared with the grades in 7 days of treatment, MAS grades of elbow joint and metacarpophalangeal joint were improved markedly in 14 days of treatment in the two groups (P<0.05). Compared with the control group, MAS grades of elbow joint and metacarpophalangeal joint were improved more markedly in the observation group in 14 days of treatment (P<0.05). Compared with the score before treatment, MBI score was increased in 7 and 14 days of treatment respectively in the observation group (P<0.05, P<0.01). In 14 days of treatment, MBI score was increased in the control group (P<0.01). CONCLUSION: For the patients with post-stroke spastic paralysis of the upper extremity at the non-acute stage, the combined treatment with kinematic-acupuncture therapy and rehabilitation training obviously improves the motor function of the upper extremity and the muscle tone of elbow joint and metacarpophalangeal joint. The therapeutic effect of this combination is better than that of the combined treatment of the conventional acupuncture with rehabilitation training. Additionally, this combined therapy improves the ability of daily life activity.

Effects of Xingnaojing Injection on Adenosinergic Transmission and Orexin Signaling in Lateral Hypothalamus of Ethanol-Induced Coma Rats.

Acute alcohol exposure induces unconscious condition such as coma whose main physical manifestation is the loss of righting reflex (LORR). Xingnaojing Injection (XNJI), which came from Chinese classic formula An Gong Niu Huang Pill, is widely used for consciousness disorders in China, such as coma. Although XNJI efficiently shortened the duration of LORR induced by acute ethanol, it remains unknown how XNJI acts on ethanol-induced coma (EIC). We performed experiments to examine the effects of XNJI on orexin and adenosine (AD) signaling in the lateral hypothalamic area (LHA) in EIC rats. Results showed that XNJI reduced the duration of LORR, which implied that XNJI promotes recovery form coma. Microdialysis data indicated that acute ethanol significantly increased AD release in the LHA but had no effect on orexin A levels. The qPCR results displayed a significant reduction in the Orexin-1 receptors (OX1R) expression with a concomitant increase in the A1 receptor (A1R) and equilibrative nucleoside transporter type 1 (ENT1) expression in EIC rats. In contrast, XNJI reduced the extracellular AD levels but orexin A levels remained unaffected. XNJI also counteracted the downregulation of the OX1R expression and upregulation of A1R and ENT1 expression caused by EIC. As for ADK expression, XNJI but not ethanol, displayed an upregulation in the LHA in EIC rats. Based on these results, we suggest that XNJI promotes arousal by inhibiting adenosine neurotransmission via reducing AD level and the expression of A1R and ENT1.
