Application of the transosseous approach for computed tomography-guided radioactive 125-iodine seed implantation for the treatment of thoracic and abdominal lymph node metastases.

AIM: This study aimed to investigate the technical procedure, safety, and clinical value of the transosseous approach for computed tomography (CT)-guided radioactive 125-iodine (125I) seed implantation for the treatment of thoracic and abdominal lymph node metastases. SUBJECTS AND METHODS: This was a retrospective study that Nine lymph node metastases in nine patients were treated in our hospital between January 2010 and August 2018. Under CT guidance, at least one puncture path was made through the transosseous approach. The seeds were planted according to the TPS. CT/MRI scans were performed every 2 months after the treatment to evaluate local therapeutic efficacy according to the Response Evaluation Criteria in Solid Tumors. RESULTS: The transosseous approach was successfully established in all patients. The median follow-up time was 11 months (6-36 months). At 2, 4, 6, 8, 10 and 12 months after operation, the objective effective rate and clinical benefit rate were 66.67%, 77.78%, 77.78%, 71.43%, 66.67% and 50.00%; and 88.89%, 88.89%, 88.89%, 71.43%, 66.67% and 50.00%, respectively. The survival rate of the patients at 6, 12, 18, 24, 30 and 36 months after operation was 53.00%, 26.00%, 26.00%, 13.00%, 13.00% and 13.00%, respectively. CONCLUSIONS: The transosseous approach for CT-guided radioactive 125I seed implantation was safe, effective, and minimally invasive for the treatment of thoracic and abdominal lymph node metastases.

Astragaloside IV sensitizes non-small cell lung cancer cells to gefitinib potentially via regulation of SIRT6.

Astragaloside IV, the active component of Astragalus membranaceus, exhibits diverse biological roles including the anti-tumor activity. In this study, we evaluated the chemosensitive role of astragaloside IV in non-small cell lung cancer cells. Cell Counting Kit-8 analysis was performed to determine cell viability. Real-time polymerase chain reaction and western blot were used to measure the messenger RNA and protein expression. Results showed that astragaloside IV treatment could suppress the proliferation of non-small cell lung cancer cells. In addition, combined treatment with astragaloside IV remarkably enhanced the chemosensitivity to gefitinib in three non-small cell lung cancer cell lines including NCI-H1299, HCC827, and A549. Furthermore, compared with gefitinib-treated cells, the messenger RNA expression of SIRT6 was obviously increased in non-small cell lung cancer cells treated with gefitinib combined with astragaloside IV. In addition, downregulation of SIRT6 was accomplished using small interference RNA technology. As a result, SIRT6 inhibition abolished the sensitization role of astragaloside IV in non-small cell lung cancer cells. Taken together, these data demonstrated that astragaloside IV sensitized tumor cells to gefitinib via regulation of SIRT6, suggesting that astragaloside IV may serve as potential therapeutic approach for lung cancer.

[Efficacy observation on Jin's three-needle therapy for allergic rhinitis of lung qi deficiency and cold syndrome].

OBJECTIVE: To compare the clinical efficacy in the treatment of allergic rhinitis (AR) of lung qi deficiency and cold syndrome between Jin's three-needle therapy and western medication. METHODS: Sixty-six patients were randomized into an acupuncture group and a western medication group, 33 cases in each one. In the acupuncture group, acupuncture was applied at three-nose points [Yingxiang (LI 20), Shangyingxiang (EX-HN 8) and Yintang (GV 29); Cuanzhu (BL 2) was added for frontal headache] and three-back points [Dazhu (BL 11), Fengmen (BL 12) and Feishu (BL 13)], once every day. Ten treatments made one session. Two sessions of treatment were required. In the western medication group, desloratadine oral suspension was prescribed, 5 mg each time, once a day, for 20 days. The scores of the symptoms and physical signs in AR patients as well as the clinical efficacy were observed between the two groups. RESULTS: The total effective rate was 93.9% (31/33) in the acupuncture group, which was better than 72.7% (24/33) in the western medication group (P < 0.05). After treatment, the scores of AR symptoms and physical signs as well as the total score were all reduced compared with those before treatment in the two groups (all P < 0.01). The score of every item in the acupuncture group was lower than that in the western medication group after treatment (score of symptoms: 4.70 +/- 2.07 vs 6.55 +/- 2. 69, score of physical signs: 0.85 +/- 0.67 vs 1.45 +/- +0.62, total score: 5.36 +/- 2.70 vs 8.00 +/- 2.91, all P < 0.01). CONCLUSION: Jin's three-needle therapy achieves superior efficacy on AR of lung-qi deficiency and cold syndrome, which is better than desloratadine oral suspension.

[Influence of needle-pricking bleeding combined with pulling-rotating manipulation on blood rheology in patients with vertebral artery type cervical spondylosis].

OBJECTIVE: To observe the effect of needle-pricking bleeding combined with pulling-rotating manipulation and simple manipulation on blood rheology in vertebral artery type cervical spondylosis (VATCS) patients, so as to analyze their mechanisms in relieving VATCS. METHODS: A total of 198 VATCS patients were randomly divided into treatment group (n=101) which was treated with needle-pricking plus pulling-rotating manipulation, and control group (n=97) which was treated with simple pulling-rotating manipulation, according to the random number table. The treatment was given once every 7 days, 9 times altogether. The peak systolic blood flow velocity (Vpeak), end-diastolic blood velocity (Vmin), pulsatility index (PI) and resistent index (RI) of bilateral vertebral arteries (VA) and basilar artery (BA) were detected by transcranial doppler sonography (TCD). Whole blood apparent viscosity and the plasma viscosity in the treatment group were determined by using a blood viscosimeter. RESULTS: Of the 101 and 97 VATCS cases in the treatment and control groups, 62 (61.38%) and 12 (12.37%) were cured basically, 23 (22.77%) and 26 (26.80%) experienced marked improvement, 14 (13.86%) and 41 (42.27%) were improved. 2 (1.98%) and 18 (18.55%) failed in the treatment, with the total effective rates being 98.01% and 81.44% separately. The effective rate of the treatment group was significantly higher than that of control group (P<0.05). Compared with pretreatment, Vpeak and Vmin of the bilateral VA and BA in the treatment group, and Vpeak of the right VA in the control group increased significantly (P<0.01, P<0.05), PI and RI of the bilateral VA and BA in the treatment group, and PI and RI of the right VA in the control group decreased significantly (P<0.01, P<0.05), suggesting a marked reduction of the vascular resistance and an apparent increase of the cerebral blood supply after the treatment. The therapeutic effects of the above-mentioned indexes of treatment group were significantly superior to those of the control group (P<0.05). In comparison with pre-treatment, the whole blood apparent viscosity (high, medium and low shear rates) and plasma viscosity of the treatment group post-treatment were obviously reduced (P<0.01, P<0.05). CONCLUSION: Needle-pricking therapy combined with pulling-rotating manipulation can significantly improve VATCS patients' clinical symptoms, which may be closely related to its effects in lowering vascular blood resistance and blood viscosity and increasing cerebral blood supply.
