TNNT1 accelerates migration, invasion and EMT progression in lung cancer cells.

BACKGROUND: Clinically, most patients with lung cancer (LC) die from tumor spread and metastasis. Specific metastasis-related molecules can provide reference for clinical prediction of efficacy, evaluation of prognosis, and search for the best treatment plan. Troponin T1 (TNNT1) is highly expressed in various cancer tissues, which affects malignant behavior of tumor cells and is related to patients' survival and prognosis. However, the role and molecular mechanism of TNNT1 in LC invasion and metastasis have not yet been investigated. METHODS: Gene expression profiling interactive analysis (GEPIA) online analysis was used to analyze TNNT1 expression in LC tissues. Quantitative real-time-polymerase chain reaction (qRT-PCR) or western blot were performed to measure TNNT1 or epithelial-to-mesenchymal transition (EMT)-related and Wnt/ß-catenin pathway-related protein expression in LC cells. After TNNT1 knockdown, cell scratch healing and transwell assays were introduced to assess cell migration and invasion, respectively. RESULTS: TNNT1 expression in LC tissues and cells was increased. TNNT1 knockdown notably impaired LC cell migration, invasion and EMT. TNNT1 knockdown inhibited Wnt/ß-catenin pathway of LC cells. Lithium chloride (LiCl) addition partially restored the inhibition of TNNT1 knockdown on migration, invasion, EMT and Wnt/ß-catenin of LC cells. CONCLUSION: TNNT1 knockdown attenuated LC migration, invasion and EMT, possibly through Wnt/ß-catenin signaling.

Effect of Acupuncture vs Sham Acupuncture on Patients With Poststroke Motor Aphasia: A Randomized Clinical Trial.

Importance: Motor aphasia is common among patients with stroke. Acupuncture is recommended as an alternative therapy for poststroke aphasia, but its efficacy remains uncertain. Objective: To investigate the effects of acupuncture on language function, neurological function, and quality of life in patients with poststroke motor aphasia. Design, Setting, and Participants: This multicenter, sham-controlled, randomized clinical trial was conducted in 3 tertiary hospitals in China from October 21, 2019, to November 13, 2021. Adult patients with poststroke motor aphasia were enrolled. Data analysis was performed from February to April 2023. Interventions: Eligible participants were randomly allocated (1:1) to manual acupuncture (MA) or sham acupuncture (SA) groups. Both groups underwent language training and conventional treatments. Main Outcomes and Measures: The primary outcomes were the aphasia quotient (AQ) of the Western Aphasia Battery (WAB) and scores on the Chinese Functional Communication Profile (CFCP) at 6 weeks. Secondary outcomes included WAB subitems, Boston Diagnostic Aphasia Examination, National Institutes of Health Stroke Scale, Stroke-Specific Quality of Life Scale, Stroke and Aphasia Quality of Life Scale-39, and Health Scale of Traditional Chinese Medicine scores at 6 weeks and 6 months after onset. All statistical analyses were performed according to the intention-to-treat principle. Results: Among 252 randomized patients (198 men [78.6%]; mean [SD] age, 60.7 [7.5] years), 231 were included in the modified intention-to-treat analysis (115 in the MA group and 116 in the SA group). Compared with the SA group, the MA group had significant increases in AQ (difference, 7.99 points; 95% CI, 3.42-12.55 points; P = .001) and CFCP (difference, 23.51 points; 95% CI, 11.10-35.93 points; P < .001) scores at week 6 and showed significant improvements in AQ (difference, 10.34; 95% CI, 5.75-14.93; P < .001) and CFCP (difference, 27.43; 95% CI, 14.75-40.10; P < .001) scores at the end of follow-up. Conclusions and Relevance: In this randomized clinical trial, patients with poststroke motor aphasia who received 6 weeks of MA compared with those who received SA demonstrated statistically significant improvements in language function, quality of life, and neurological impairment from week 6 of treatment to the end of follow-up at 6 months after onset.

[Study on the correlation between the thickness of superficial fascia at Dazhui(GV14) and cervical spondylosis].

OBJECTIVE: To observe the correlation between the thickness of superficial fascia at Dazhui (GV14) acupoint and cervical spondylosis, so as to explore the essence of its morphological and structural changes of acupoint sensitivity. METHODS: A retrospective study was conducted. According to the diagnostic criteria of "Guidelines for Diagnosis, Treatment and Rehabilitation of Cervical Spondylosis" (2017), 344 cases of cervical spine magnetic resonance imaging (MRI) examination were included and divided into control group (73 cases) and observation group (271 cases). The control group was healthy population, and the observation group was patients with cervical spondylosis conforming to the diagnostic criteria, including cervical spondylosis of neck type, cervical spondylosis radiculopathy, cervical spondylotic myelopathy, cervical spondylosis of vertebral artery type, and sympathetic cervical spondylosis. According to MRI images of cervical spine, the structure of GV14 acupoint including skin, superficial fascia layer and aponeurosis ligament layer were measured. RESULTS: The acupoint depth and the superficial fascia thickness at GV14 in the observation group were (56.6±8.8) mm and (22.8±7.6) mm, the acupoint depth and the superficial fascia thickness at GV14 were (49.8±7.0) mm and (16.6±6.6)mm in the control group, which were significantly greater in the observation group than in the control group (P<0.01). The superficial fascia thickness at GV14 of cervical spondylotic mye-lopathy, cervical spondylosis of neck type and cervical spondylosis radiculopathy in the observation group was (23.8±8.1)mm, (23.0±7.3)mm and (22.6±6.5)mm, the acupoint depth of GV14 was (58.7±8.8)mm, (56.2±9.1)mm and (55.8±6.4)mm, which were significantly thicker than the superficial fascia thickness and the acupoint depth in the control group (P<0.01). In the observation group，the superficial fascia thickness of GV14 of cervical spondylosis myelopathy was significantly thicker than those of sympathetic cervical spondylosis (17.8±8.1) mm and cervical spondylosis of vertebral artery type (19.9±5.9) mm (P<0.01, P<0.05). In the observation group, the depth of GV14 of cervical spondylosis myelopathy was thicker than that of cervical spondylosis of neck type, cervical spondylosis radiculopathy, sympathetic cervical spondylosis and cervical spondylosis of vertebral artery type(P<0.05，P<0.01)； the depth of GV14 of sympathetic cervical spondylosis was thinner than that of cervical spondylosis of neck type and cervical spondylosis radiculopathy (P<0.01). CONCLUSION: The superficial fascia thickness at GV14 was correlated with cervical spondylosis, and it is also related to cervical spondylotic myelopathy, cervical spondylosis of neck type and cervical spondylosis radiculopathy. The morphological and structural changes of GV14 in the state of cervical spondylosis were mainly the thickness of the superficial fascia.

Effect of electroacupuncture at different acupoints in treating rapid gastric emptying: Zusanli (ST36) plus Zhongwan (CV12) versus Zhongwan (CV12) alone.

OBJECTIVE: To evaluate the effect of electroacupuncture on rapid gastric emptying by comparing the effectiveness of electroacupuncture at both Zusanli (ST36) and Zhongwan (CV12) (He-Mu acupoints) versus electroacupuncture at Zhongwan (CV12) alone. METHODS: Sixty-five patients were randomly divided into two groups; 33 patients in the He-Mu acupoints group received electroacupuncture at both Zusanli (ST36) and Zhongwan (CV12), while 32 patients in the single acupoint group received electroacupuncture only at Zhongwan (CV12). Both groups were treated once daily for 30 min, five times per week for 3 weeks. Before and after the 3-week treatment course, patients underwent gastric emptying scintigraphy and were assessed using the Traditional Chinese Medicine (TCM) symptom scale of gastrointestinal diseases. The two groups were compared regarding the percentages of gastric retention at 30 and 60 min and the TCM symptom scores. RESULTS: After the treatment course, the percentages of gastric retention at 30 and 60 min were significantly improved in both groups compared with the pre-treatment values (P < 0.01). The improvement in the gastric retention was significantly better in the He-Mu acupoints group than the single acupoint group at 30 min (P <0.01) and 60 min (P < 0.05). The TCM symptom score was significantly decreased after the treatment course in both groups (P < 0.01). The improvement in the TCM symptom score was significantly better in the He-Mu acupoints group than the single acupoint group (P < 0.01). The total effective rate was 93.55% (29/31) in the He-Mu acupoints group and 77.42% (24/31) in the single acupoint group. The treatment effect was better in the He-Mu acupoints group than the single acupoint group (P < 0.05). CONCLUSIONS: Electroacupuncture at both Zusanli (ST36) and Zhongwan (CV12) or at Zhongwan (CV12) alone is effective in treating rapid gastric emptying. Furthermore, electroacupuncture at both Zusanli (ST36) and Zhongwan (CV12) is more effective than electroacupuncture at Zhongwan (CV12) alone.

[Comparative study on effect of electroacupuncture at lower he-sea point of stomach and he-sea matching front-mu points for gastroparesis].

OBJECTIVE: To explore the efficacy difference of electroacupuncture at lower he-sea point and he-sea matching front-mu points for the treatment of gastroparesis. METHODS: A total of 63 patients with gastroparesis were randomly divided into a lower he point group (group A, 32 cases, 2 cases dropped off) and a he matching mu points group (group B, 31 cases, 1 case dropped off). The group A was treated with electroacupuncture at Zusanli (ST 36), and the group B was treated with electroacupuncture at Zusanli (ST 36) and Zhongwan (CV 12). Both groups were treated with continuous wave (2 Hz in frequency) for 30 min, once a day, 5 times a week for 3 weeks. The gastroparesis cardinal symptom index (GCSI) score, gastric half-emptying time (T1/2) and the 180 min gastric residual rate of the two groups before and after treatment were observed, and the clinical effective rate was compared. RESULTS: After treatment, the total GCSI scores, T1/2 and the 180 min gastric residual rates in both groups were lower than those before treatment (P<0.01), and the 180 min gastric residual rate and T1/2 in the group A were lower than those in the group B (P<0.05). The total effective rate was 93.3% (28/30) in the group A, which was superior to 70.0% (21/30) in the group B (P<0.05). CONCLUSION: Electroacupuncture at lower he-sea point and he-sea matching front-mu points can both be used to treat gastroparesis, but electroacupuncture at Zusanli (ST 36) has a better effect. The acupoints of Zusanli (ST 36) and Zhongwan (CV 12) may have antagonistic effects.

[Effect on tranquilizing and allaying excitement needling method on brain blood flow in the patients of insomnia of heart and spleen deficiency].

OBJECTIVE: To observe the therapeutic effect of tranquilizing and allaying excitement needling method on insomnia of heart and spleen deficiency and the effect of brain blood flow. METHODS: Sixty cases were randomly divided into a tranquilizing and allaying excitement needling method group (observation group) and an eight confluence points selected group (control group), 30 cases in each group. The observation group was treated by acupuncture at Sishencong (EX-HN 1), Shenmen (HT 7), and Sanyinjiao (SP 6) with tranquilizing and allaying excitement needling method. The control group was treated by acupuncture at Shenmai (BL 62) and Zhaohai (KI 6). Their therapeutic effects and changes of brain blood flow were observed. RESULTS: The total effective rate was 93.3% (28/30) in the observation group which was better than 83.3% (25/30) in the control group (P < 0.05). After treatment, the peak velocity of systolic (Vp) and diastolic blood flow velocity (Vd) of middle cerebral artery, basilar artery and vertebral artery were increased in the both groups (P < 0.01, P < 0.05), with more obvious increase in the observation group (P < 0.01, P < 0.05), except the Vd of left vertebral artery. CONCLUSION: Both the tranquilizing and allaying excitement needling method and the eight confluence points selected needling method can improve the clinical signs and symptoms. Meanwhile, the therapeutic effect of acupuncture is related with improvement of brain blood flow. However, the tranquilizing and allaying excitement needling method has better therapeutic effect on insomnia of heart and spleen deficiency.

A survey of the studies on white tiger shaking head method described by ancient and modern physicians.

Having studied white tiger shaking head method described by ancient and modern physicians, and analyzed and compared its manipulation techniques, the authors believe that the core of white tiger shaking head method originating from Zhenjiu Daquan ([Chinese characters: see text] Complete Book of Acupuncture-Moxibustion) by XU Feng lies in the techniques of "squarely withdrawing and circularly inserting" and "shaking and vibrating", and the manipulation factor is "circularly inserting and shaking, and squarely withdrawing and vibrating". Physicians such as WANG Ji (his second method), YANG Ji-zhou, LU Shou-kang and ZHENG Kui-shan inherited and developed white tiger shaking head method. WANG Ji's first method and what LI Chan and modem physicians YANG Zhao-min and LU Shou-yan described do not belong to white tiger shaking head method. The authors have made a new suggestion on standardizing the manipulation of white tiger shaking head method and approached to new ideas on research into standardization of ancient acupuncture.
