ABSTRACT

@#Objective    To compare clinical effects of enlarged thymectomy for the treatment of myasthenia gravis (MG) complicated with thymoma via subxiphoid and subcostal arch thoracoscopic resection versus median sternotomy resection. Methods    We retrospectively analyzed the clinical data of patients with MG complicated with thymoma admitted in Tangdu Hospital of the Air Force Military Medical University between December 2011 and December 2021. Patients who underwent subxiphoid and subcostal arch thoracoscopic enlarged thymectomy were allocated to a SR group, and patients who underwent median sternotomy enlarged thymectomy were allocated to a MR group. Perioperative outcomes were compared between the two groups. Results    A total of 456 patients were collected. There were 51 patients in the MR group, including 30 males and 21 females aged 23-66 (49.5±11.8) years. There were 405 patients in the SR group, among whom 51 patients were matched to the MR group by propensity score matching, including 28 males and 23 females aged 26-70 (47.2±12.2) years. The operations were accomplished successfully in all patients, and no conversion to thoracotomy occurred in the SR group. The SR group had advantages in the operation time, intraoperative blood loss,  chest drainage duration, hospital stay time, patients’ satisfaction level, pain score and complications (all P<0.05). No statistical difference was found in the number of intraoperative lymph node dissection stations, number of intraoperative lymph nodes dissected or remission of MG between the two groups (P>0.05). Conclusion    Subxiphoid and subcostal arch thoracoscopic enlarged thymectomy and lymphadenectomy is a safe, effective and feasible minimally invasive procedure for the treatment of MG complicated with thymoma.

ABSTRACT

@#Objective    To compare clinical effects of extended thymectomy for the treatment of thymic abnormalities with myasthenia gravis (MG) between subxiphoid and subcostal arch thoracoscopic resection (SR) and the unilateral thoracoscopic resection (UR) by a propensity-score matching analysis. Methods    We retrospectively analyzed the clinical data of 612 patients who presented with MG and were admitted to Tangdu Hospital of Air Force Military Medical University between December 2011 and December 2018. Of these patients, 520 patients underwent subxiphoid and subcostal arch thoracoscopic extended thymectomy (a SR group) and 92 unilateral thoracoscopic extended thymectomy (a UR group). Ninety-two patients in the SR group were matched with the UR group by propensity-score matching analysis. There were 52 males and 40 females with an average age of 26-70 (50.2±10.3) years in the SR group, and 47 males and 45 females with an average age of 20-73 (51.5±12.1) years in the UR group. The operation time, intraoperative blood loss, thoracic drainage time, postoperative hospital stay, thorough adipose tissue removal, postoperative remission of MG, patients’ satisfaction score, pain and complications were compared and analyzed between the two groups. Results    All operations were accomplished successfully, without conversion to thoracotomy of the two groups. There were statistical differences between the two groups in operation time (46.2±19.5 min vs. 53.4±23.5 min), chest drainage duration (0 d vs. 3.4±1.2 d), hospital stay (2.9±1.9 d vs. 3.6±1.7 d), patients’ satisfaction score (7.9±2.1 points vs. 6.7±1.2 points) and pain scores (all P<0.05). There were no statistical differences between the two groups in intraoperative blood loss (52.2±12.7 mL vs. 51.2±10.3 mL), peripheral adipose tissue removal (8.1±0.6 vs. 7.9±0.9), remission rate of MG (89.1% vs. 85.9%) and rate of postoperative complications (10.9% vs. 6.5%) (all P>0.05). Conclusion    Subxiphoid and subcostal arch thoracoscopic extended thymectomy is a safe and feasible minimally invasive procedure for the management of MG with thymic abnormalities.

ABSTRACT

Objective:To investigate the protective effect of Yiqi Huazhi recipe Quqian granules on rat renal tubular cell apoptosis induced by lead poisoning. Methods:Totally 60 Wistar rats were divided into 2 groups, 12 in the control group and the others in the model group. Chronic lead poisoning model was made by drinking 0. 02% lead acetate water for 60 days. Then the lead poisoning rats were randomly divided into four groups, high-dose Quqian granules group (3. 0 g·kg-1·d-1), low-dose Quqian granules group (0. 6 g·kg-1 ·d-1 ) , positive control group ( calcium disodium edentate plus procaine, im, 50 mg·kg-1 ·d-1 ) and model group. Seven treatment courses were carried out in the first three groups with every 4-d as one course and 4-d withdrawal period between every two courses. After 60 days, the change of lead in blood and kidney was observed by atomic absorption spectrometry,the apoptosis of kidney tissues was studied by TUNEL, the expression of Bcl-2 protein was detected by immunohistochemical methods and the expression of p53 was studied by Western Blotting. Results:Compared with the control group, the body weight, hemoglobin and the expression of Bcl-2 in the model group were decreased significantly(P<0.01)those in, and Pb in blood(0.990 ±0.443)μg·ml-1, Pb in kidney(51.33 ± 5. 16)μg·ml-1 , the apoptosis of tubular epithelial cell(4. 148 ± 0. 414) and the expression of p53 protein (1. 868 ± 0. 139) were significantly higher (P<0. 05). Compared with the those in model group, the body weight, hemoglobin and Bcl-2 in high-dose group were increased significantly(P<0.01), and the blood lead level (0.082 ±0.015)μg·ml-1, the kidney lead level (6.38 ±0.97)μg ·ml-1 , the apoptosis of tubular epithelial cell(1. 412 ± 0. 109) and p53 protein expression(1. 164 ± 0. 172) were significantly lower (P<0. 05). Conclusion:Lead may induce high expression of p53,low expression of Bcl-2 and promote the apoptosis of renal tubular epithelial cells. It is proven that Yiqi Huazhi recipe Quqian granules can inhibit the expression increase of p53 and the expression de-crease of Bcl-2 resulting in the reduction of the renal tubular apoptosis to allivate the renal injury caused by lead.

ABSTRACT

Glycoprotein (GP) Ibα ectodomain shedding has important implications for thrombosis and hemostasis. A disintegrin and metalloproteinase 17 (ADAM17) was identified to play an essential role in agonist induced GPIbα shedding. The relationship of GPIbα shedding and ADAM17 in the acute stage of atherosclerotic ischemic stroke (AIS) patients has not been thoroughly studied. A total of 306 patients and 230 controls matched for age, sex, race, history of hypertension and diabetes mellitus were enrolled in the study. GPIbα, ADAM17, glycocalicin were detected by flow cytometry, Western blotting, and enzyme-linked immunosorbent assay (ELISA) respectively. Compared with the control group, the expression of GPIbα in patients with acute ischemic stroke was significantly lower (P=0.000, P<0.01). Plasma glycocalicin and ADAM17 in AIS group were higher than those in control group (P=0.699, P=0.000). Pearson's analysis showed glycocalicin bore no correlation with GPIbα in AIS patients (r=0.095, P>0.05). GPIbα and National Institute of Health Stroke Scale (NIHSS) had negative correlation (r=-0.514, P<0.01). Our findings indicate that ADAM17 may be a risk factor for ischemic stroke in Chinese and the expression of GPIbα can serve as a measure for stroke severity.

ABSTRACT

OBJECTIVE: A series of recent studies have demonstrated the mechanism of migration and nerve net of neural stem cells. These theories have further substantiated neural stem cell transplantation. In view of these new findings, this paper reviewed the mode of migration and information of network. The significance of these theories was discussed.DATA SOURCE: We search on Pubmed with the key words "neural stem cell", "migration", and "nerve net", limiting the language to English and publication date from 1970 to 2004. At the same time we searched on CNKI.STUDY SELECTION: We selected the randomized and non-randomized controlled studies related to migration and nerve net building of neural stem cells. Review articles and articles with repetitive studies were excluded.DATA EXTRACTION: Among 39 papers selected, 16 papers concerning the development of this topic were selected, and the others were excluded.DATA SYNTHESIS: For retrograde lesions and severe injury of nervous system, transplantation of nerve stem cells may replace aging degenerative and dead nerve cells and rebuild neural network for the recovery of cerebral function. Migration of nerve cell and network principle can solve the survival, differentiation, migration and creation of nerve network after transplantation of nerve stem cells so as to realize the recovery and reconstruction of cerebral function.CONCLUSION: Neural stem cells can migrate to intended places and can build nerve net under some conditions, which will be useful for medicine deyelopment.

ABSTRACT

By applying the methods of inter—element meter andmean line,decoction solution of 110 recipes were anal-ysed for the characteristics of distribution of inorganicelements.In those recipes containing more warm-heat drugs,the contents of most elements were higherthan the line of average value,while those with morecool—cold drugs,lower than the mean line,suggest-ing that the distribution value of inorganic elementsmay be a determining factor responsible for the cold-heat quality of a recipe.
