1.Apropos of one case of successful treating for ventrical fibrillation and cardiac arrest during performance of percutaneous transluminal coronary angioplasty and stenting in acute myocardial infarction patient
Journal of Practical Medicine 2005;510(4):79-81
Study on one case of ventrical fibrillation and cardiac arrest during performance of percutaneous transluminal coronary angioplasty (PTCA) and stenting in acute myocardial infarction patient at Central Military Hospital 108. Results: the complication of arrhythmia, ventrical fibrillation and cardiac arrest often occurred in patient with acute inferoposterior wall myocardial infarction. Stent-related complications included embolism, coronary piercing and hemorrhage. All equipment and drugs should be prepared when performing PTCA and stenting, especially patients with arrhythmia must be observed by ICU doctor. Electric defibrillation is the most effective treatment of ventrical fibrillation during PTCA and stenting. If CPR has been done correctly, the patient would fully recover although the time of asystole was more than 10 minutes.

2.Significance of some blood gas parameters in hyperbaric oxygenation therapy for chronic cor pulmonale
Journal of Practical Medicine 1999;367(7):9-11
Blood gas parameters were measured in 20 patients with chronic cor pulmonale before and after a course of hyperbaric oxygenation therapy (HBO). Results found that the HBO has increased PaO2 of patients from 73.8mmHg to 81.1mmHg and reduced AsDO2 from 26.5mmHg to 19.9mmHg with p<0.05. Except parameters of PaO2, pH and PaCO2, other parameters such as AaDO2, PaO2 and P50 must be measured in order to evaluate completely the effect of HBO. (Auth)

Objective:
To evaluate the effectiveness and safety of electroacupuncture in conjunction with additional medications in providing analgesia and stabilizing hemodynamic parameters during total thyroidectomy.
Methods:
This randomized controlled trial included 100 patients who underwent a total thyroidectomy between October 2022 and October 2023 at the Vietnam National Hospital of Acupuncture. The patients were randomized into two groups. The electroacupuncture analgesia (EA) group received EA stimulation at five acupuncture points: Hegu (LI 4), Neiguan (PC 6), Shuitu (ST 10), Quepen (ST 12), and Yifeng (SJ 17), while the control group received a bilateral superficial cervical plexus block. Primary outcomes included the level of analgesia and perioperative vital signs in both groups. Additionally, pain thresholds and serum β-endorphin levels were measured before and after electroacupuncture in the EA group.
Results:
Complete analgesia (Level A) was attained in 86% and 76% of the patients in the EA and control groups, respectively, with no significant difference between the two groups (P = 1.00). In the EA group, the mean pain threshold after receiving EA doubled (648.7 (77.4) g/s vs. 305.3 (45.3) g/s, P < .001), and the mean serum β-endorphin level increased by approximately 13.5 pg/mL (P < .001). All patients remained hemodynamically stable throughout the surgery.
Conclusion
EA, in conjunction with additional medications that stimulate five acupuncture points, LI 4, PC 6, ST 10, ST 12, and SJ 17, was well tolerated and effectively maintained a suitable level of analgesia and hemodynamic stability during total thyroidectomy.

In this report, we investigated the antioxidant (peroxyl radical-scavenging and reducing capacities) and anti-osteoporotic activities of extracts and isolated constituents (1 - 16) from the rhizomes of Kaempferia parviflora Wall. ex Baker on pre-osteoclastic RAW 264.7 cells. Compound 5 exhibited significant peroxyl radical-scavenging capacity, with TE value of 8.47 ± 0.52 µM, while compound 13 showed significant reducing capacity, with CUPRAC value of 5.66 ± 0.26 µM, at 10.0 µM. In addition, flavonoid compounds 2, 4, 6, 8, 10, 12, and terpene compound 15 showed significant inhibition of tartrate-resistant acid phosphatase (TRAP) in NF-κB ligand-induced osteoclastic RAW 264.7 cells, with values ranging from 16.97 ± 1.02 to 64.67 ± 2.76%. These results indicated that K. parviflora could be excellent sources for the antioxidant and anti-osteoporotic traditional medicinal plants.

In the present study, rutile phase titanium dioxide nanoparticles (R-TiO₂ NPs) were prepared by hydrolysis of titanium tetrachloride in an aqueous solution followed by calcination at 900℃. The composition of R-TiO₂ NPs was determined by the analysis of X-ray diffraction data, and the characteristic features of R-TiO₂ NPs such as the surface functional group, particle size, shape, surface topography, and morphological behavior were analyzed by Fourier-transform infrared spectroscopy, scanning electron microscopy and energy dispersive X-ray spectroscopy, transmission electron microscopy, dynamic light scattering, and zeta potential measurements. The average size of the prepared R-TiO₂ NPs was 76 nm, the surface area was 19 m²/g, zeta potential was −20.8 mV, and average hydrodynamic diameter in dimethyl sulfoxide (DMSO)–H₂O solution was 550 nm. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and morphological observations revealed that R-TiO₂ NPs were cytocompatible with oral cancer cells, with no inhibition of cell growth and proliferation. This suggests the efficacy of R-TiO₂ NPs for the aesthetic white pigmentation of teeth.

Ophiopogonin D (OPD) is a steroidal glycoside derived from Ophiopogon japonicus, a traditional Chinese medicine with diverse biological activities, including antithrombosis, anti-inflammation, and antitussive effects. To investigate the cellular effects and mechanisms of OPD on oral squamous cell carcinoma, cell viability was explored, and the effects of OPD on cell cycle regulators, apoptotic marker proteins, and key proteins involved in metastasis and signaling pathways were examined by MTT assay and Western blotting in YD38 cells. OPD strongly inhibited cell proliferation and induced caspase-dependent apoptosis of YD38 cells by suppressing the cell cycle and activating caspase-3 and poly ADP ribose polymerase. Additionally, OPD suppressed the expression of vital proteins regulating metastasis and proliferation within the integrin/matrix metalloproteinases/FAK and AKT/PI3K/mTor pathways. Thus, OPD can be a potential treatment candidate for gingival cancer.

Liver cancer is a common tumor and currently the second leading cause of cancer-related mortality globally. Liver cancer is highly related to inflammation as more than 90% of liver cancer arises in the context of hepatic inflammation, such as hepatitis B virus and hepatitis C virus infection. Despite significant improvements in the therapeutic modalities for liver cancer, patient prognosis is not satisfactory due to the limited efficacy of current drug therapies in anti-metastatic activity. Therefore, developing new effective anti-cancer agents with anti-metastatic activity is important for the treatment of liver cancer. In this study, SP-8356, a verbenone derivative with anti-inflammatory activity, was investigated for its effect on the growth and migration of liver cancer cells. Our findings demonstrated that SP-8356 inhibits the proliferation of liver cancer cells by inducing apoptosis and suppressing the mobility and invasion ability of liver cancer cells. Functional studies revealed that SP-8356 inhibits the mitogen-activated protein kinase and nuclear factor-kappa B signaling pathways, which are related to cell proliferation and metastasis, resulting in the downregulation of metastasis-related genes. Moreover, using an orthotopic liver cancer model, tumor growth was significantly decreased following treatment with SP-8356. Thus, this study suggests that SP-8356 may be a potential agent for the treatment of liver cancer with multimodal regulation.
