[Effect of "Tongyuan" acupuncture treatment on success rate of extubation in stroke patients undergoing tracheotomy].

OBJECTIVE: To observe the impact of "Tongyuan" (regulating the Governor Vessel to tranquilize mental activities, conducting qi back to its origin) acupuncture treatment on cough reflex, pulmonary infection and swallowing function in stroke patients undergoing tracheotomy. METHODS: Seventy-four cerebral stroke patients with tracheo-tomy were randomly allocated to scalp acupuncture and "Tongyuan" acupuncture groups (n=37 in each group). All the patients of the two groups received basic treatment, including treatment of primary diseases, routine nursing, respiratory muscle training, physical therapy, acupuncture of Chize (LU5), Quchi (LI11), Hegu (LI4), Weizhong (BL40), Zusanli (ST36). In addition, for patients of the scalp acupuncture group, the middle 2/5 of Dingnieqianxiexian (MS6), the middle 2/5 of Dingniehouxiexian (MS7) and Dingpangerxian (MS9) on the contralateral side of lesions were punctured with filiform needles. For patients of the "Tongyuan" acupuncture group, Baihui (GV20), Zhongwan (GV12), Guanyuan (CV4), Qihai (CV6), Tianshu (ST25), Feishu (BL13), Pishu (BL20) were needled. The treatment in both groups lasted 30 minutes each time, once daily, 6 times a week for 4 weeks. The cough reflex grading score (CRGS, assessed according to cough, independent expectoration, sputum suction), clinical pulmonary infection score (CPIS, assessed according to the body temperature, white blood cell count, airway secretion in 24 h, PaO2/FiO2, infiltration status, cultured pathogenic bacteria), and swallowing function were evaluated by a researcher who was blinded to the grouping and treatment procedures. The success rate of extubation was calculated in a week at the end of treatments. RESULTS: After the treatment, the CRGS and CPIS of both groups were apparently decreased in comparison with their own pre-treatment (P<0.05), suggesting an improvement of the cough reflex and pulmonary infection. Regarding the swallowing function, of the two 37 cases in the scalp acupuncture and "Tongyuan" acupuncture groups, 9(24.3%) and 19(51.4%) experienced marked improvement, 12(32.5%)and 14(37.8%) were effective, and 16(43.2%) and 4(10.8%)failed in the treatment, with the effective rate being 56.8% and 89.2%, respectively. In regard to the successful extubation, of the two 37 cases in the scalp acupuncture and "Tongyuan" acupuncture groups, 5(13.5%) and 11(29.8%)had a marked improvement, 10(27.0%)and 18(48.6%)were effective, and 22(59.5%)and 8(21.6%)failed, with the effective rate being 40.5% and 78.4%, respectively. The therapeutic effect of "Tongyuan" acupuncture was significantly superior to that of scalp acupuncture in decreasing CRGS and CPIS, and in improving the swallowing function and raising the rate of successful extubation (P<0.05). CONCLUSION: "Tongyuan" acupuncture treatment can improve cough reflex to remove sputum, reduce pulmonary infection, enhance swallowing function, and raise the success rate of extubation in stroke patients, which is better than scalp acupuncture.

Extraskeletal osteosarcoma in right neck subcutaneous tissue: A case report of an extremely rare tumour.

Extraskeletal osteosarcoma (ESOS) is a rare soft-tissue sarcoma that is treated with surgical resection, chemotherapy and radiotherapy; however, as it is now considered to be radiation resistance, it is associated with conflicting management principles and poor outcomes. A multimodality approach is currently used to treat ESOS, which entails the incorporation of multidrug chemotherapy and/or radiotherapy coupled with surgery to obtain the best outcome; however, there are many factors that influence the treatment effects and clinical outcomes of ESOS. In the present study, a case of an 81-year-old man who suffered from primary ESOS in the subcutaneous tissue of the right-hand side of the neck was reported. The patient was treated several times with partial resection and once with radiotherapy, and was still living following 3 years of follow-up. Thus, the present case report demonstrated that surgical resection and postoperative radiotherapy regimens may be favourable in the short term with a disease-free survival of ~15 months; however, patients are prone to relapse.

Beneficial effect of farnesoid X receptor activation on metabolism in a diabetic rat model.

Farnesoid X receptor (FXR) is an important regulator of glucose and lipid homeostasis. However, the exact role of FXR in diabetes remains to be fully elucidated. The present study examined the effects of chenodeoxycholic acid (CDCA), an agonist of FXR, on metabolism profile in a rat model of type 2 diabetes mellitus (T2DM). Male Wistar rats (8­week­old; n=40) were randomized into the following four groups (n=10): Untreated control, CDCA­treated, T2DM, and CDCA­treated T2DM. To establish the T2DM model, the rats were fed a high­fat diet (HFD) for 4 weeks and received a single low­dose intraperitoneal injection of streptozotocin (30 mg/kg), followed by an additional 4 weeks of HFD feeding. CDCA was administrated (10 mg/kg/d) intraperitoneally for 10 days. Reverse transcription­quantitative polymerase chain reaction and western blotting assays were performed to determine the RNA and protein expression of FXR, phosphoenolpyruvate carboxykinase, G6Pase, proliferator­activated receptor­Î³ coactivator­1 and short heterodimer partner in rat liver tissue. The results revealed that FXR activation by CDCA did not reduce body weight, but it lowered the plasma levels of fasting glucose, insulin and triglycerides in the T2DM rats. CDCA administration reversed the downregulation of the mRNA and protein expression of FXR in the T2DM rat liver tissue samples. Furthermore, treatment with CDCA reduced the mRNA and protein expression levels of phosphoenolpyruvate carboxykinase, glucose 6­phosphatase and peroxisome proliferator­activated receptor­Î³ coactivator­1 in the liver tissue samples of the T2DM rats. By contrast, CDCA treatment increased the mRNA and protein expression levels of short heterodimer partner in the liver tissue samples of the T2DM rats. In conclusion, FXR agonist treatment induces beneficial effects on metabolism in the rat T2DM model. In conclusion, the present study indicated that the FXR agonist may be useful for the treatment of T2DM and hypertriglyceridemia.

[Diagnosis and treatment of penetrating injury to the left ventricle].

OBJECTIVE: To review our experiences with diagnosis and treatment of 6 cases of penetrating injury to the left ventricle. METHODS: Six patients were admitted to the emergency department 0.5 to 3 h after the injury, all with shock and 3 with obvious pericardiac tamponade. All the patients received immediate thoracotomy for repairing the ruptured left ventricle, sub-pericardial window and pericardiocentesis, with also blood autotransfusion. RESULTS: All patients survived the operations. One patient required reexploration because of hemorrhage in the chest and two presented ST-segment changes in postoperative ECG, and one had nonspecific intraventricular conduction delay with T-wave inversion. CONCLUSIONS: Penetrating injury to the left ventricle is manifested by low blood pressure and signs of pericardial tamponade. Immediate thoracotomy to relieve the tamponade and effective hemostasis can be critical for management of such patients.
