Objective To compare the clinical therapeutic effects of thyroid endoscopic surgery and traditional open surgery in treatment of thyroid diseases.Methods Data of 136 patients undergoing thyroid surgery from May.2011 to May.2012 in the Second People's Hospital of Yunnan Province were collected.They were randomly divided into 2 groups:the observation group (n =68) and the control group (n =68).The observation group were treated with endoscopic thyroid surgery and the control group with the traditional surgery.Clinical data of the 2 groups such as operation time,intraoperative blood loss,postoperative drainage volume,postoperative serum interleukin 2 (IL-2),C reaction protein(CRP),TNF-αexpression level,postoperative complications,postoperative hospital stay and so on were collected and compared.Results The difference had no statistical significance between the 2 groups in the operation time,intraoperative blood loss,postoperative drainage volume,postoperative serum IL-2,CRP,TNF-αexpression levels,and postoperative complications (P ＞ 0.05).However,the observation group had superiority in the postoperative hospital stay,neck discomfort and the acceptability than the control group.The difference had statistical significance (P ＜ 0.05).Conclusions Endoscopic thyroid surgery is safe and reliable.Compared with traditional open surgery,it has better cosmetic effects and less trauma.

Objective To observe the synapse formation in hippocampal dentate gyrus, and the memory ability after transplanting bone marrow stromal cells (BMSCs) into lateral ventricle of ischemic brain injury rats. Methods BMSCs from femur of a Sprague-Dawley rat were cultured for 3 generations in vitro. 60 newborn Sprague-Dawley rats were divided into sham group (n=20), model group (n=20) and BMSCs group (n=20). The latter 2 groups were ligated the left common carotid artery, and the BMSCs group were injected BMSCs into the lateral ventricle 7 days after ligation. They were tested with Morris's water maze 8 weeks later, and then, the brains were immunohistochemical staining to detect synaptophysin (SY). Results The time of probe trial of acquisition phase (T1) and reveral phase (T2) decreased in the model group compared with the sham group (P<0.05), and increased in the BMSCs group compared with the model group (P<0.05). The integral optical density (IOD) of SY positive cells decreased in the model group compared with the sham group (P<0.05), and increased in the BMSCs group compared with the model group (P<0.05). Conclusion BMSCs implantation through lateral ventricle can improve the learning and memory ability of rats, which may associated with the synapse formation in dentate gyrus.

Objective To investigate the changes of SCD 14, TNF-?, E-SLT and IL-10 level in the process of infection.Methods Serum E-SLT, IL-10, SCD 14 and TNF-? level was measured in 37 patients of abdominal trauma, and in model rabbits with endotoxemia.Results Serum level of SCD 14,TNF-?,E-SLT and IL-10 on the 1st to 3rd day post-op increased significantly in patients suffering from post-op infection 〔(1.61?0.47)??g/ml, (28.63?8.29)?pg/ml,(153.6?48.9)?ng/ml and (38.21?10.87)?pg/ml, compared with control, all P

Objective To investigate the feasibility and effectiveness of internal jugular vein (IJV) intervention therapy in patients with cerebral venous sinus thrombosis (CVST)with color Doppler ultrasound (CDU). Methods Twelve patients with CVST diagnosed by CDU and the 13 IJV lesions (localized luminal stenosis in 9 cases,venous long-segment slender in 2 cases,and right IJV localized luminal stenosis,and long-segment slender on the left in 1 case)confirmed by magnetic resonance venography (MRV)and/ or digital subtraction angiography (DSA)were enrolled retrospectively. CDU examinations were used at 1 week before and after IJV intervention therapy,6 months,1 year,and 2 years. The changes of the maximum diameter and the maximum velocity (V max )of the IJV were compared. The success rate and the long-term efficacy of the intervention therapy were analyzed. Results One week after treatment,the CDU examinations showed that the diameter of IJV stenosis in 13 IJV were increased significantly compared with those before procedure (4. 7 ± 2. 1 mm vs. 2. 3 ± 1. 3 mm;t = 5. 325,P < 0. 01). The velocity of blood flow of IJV was improved compared with before procedure (localized stenosis in 10 IJV[50 ± 15 cm/ s vs. 87 ± 24 cm/ s];t = 6. 285,P < 0. 01). Six of the 12 patients were followed up for a mean of 18 ± 7 months, two patients had restenosis after balloon dilatation. Conclusions For CVST patients with IJV lesions,the preliminary observation has indicated that IJV intervention therapy may improve the lesion lumen and hemodynamics. However,the intervention therapy,especially after balloon dilatation,the incidence of restenosis is higher. CDU can be used as an objective evaluation means for the long-term efficacy of IJV stenosis.

Objective To analyze the expression of glial fibrillary acidic protein(GFAP) in hippocampal of rats with hypoxic-ischemic brain damage(HIBD) after injection of bone marrow stromal cells(BMSCs) supernatant into the lateral ventricle of the neonate rats,assess the ability of learning and memory,and explore the mechanism.Methods 7-day-old SD rats were randomly divided into sham operation group,model group,cells and supernatant group,with 20 rats in each group.The HIBD model was established via the ligation of left carotid arteries followed by 2-hour hypoxia.One week later,rats in control group were injected with 0.01 mol/L PBS 2 μl via the left ventricle.Meanwhile,the cell and the supernatant groups were injected with BMSCs and supernatant harvested from BMSC culture,respectively,via the same route.In the sham operation group,the left carotid arteries were separated but not ligated,and no hypoxia treatment was imposed on this group.They also received 0.01 mol/L PBS injection 2 μl per weak post surgery.8 weeks later,Morris water maze test was performed to assess the learning and memory,and the expression of GFAP in the dentate gyrus of rats was measured by immunohistochemistry.Results Morris water maze showed that the searching time of the probe trail(T1:(15.40±2.80) s) and reversal probe trail (T2:(16.45± 1.16) s) of the model group was shorter than that of the sham operation group (T1:(19.96±2.57) s,T2:(2:25.32±2.54)s,P＜0.05),while the searching time of the cell group(T1:(17.54± 1.80)s,T2:(18.99± 1.47) s) and supernatant group (T1:(17.40±2.37) s,T2:(17.96± 1.09) s) was prolonged compared with that of the model group (P＜0.05).No significant difference between the cell group and the supernatant group (P＞0.05).The integral optical density (IOD) value of GFAP positive cells was higher in the model group than that in the sham operation group(15.26±1.49 vs 12.82±2.56,P＜0.05),while the IOD of cell group(18.13±1.97) and that of the supernatant group(17.38± 1.64) were higher than that of the model group (P＜0.05).However,there was no significant difference between the cell group and the supernatant group (9＞0.05).Conclusion BMSC supernatant injected through lateral ventricle can improve the HIBD rats' abilities of learning and memory.The mechanism might be that MSCs secrete some cytokines to promote central nervous system repair.

Objective To summarize the progress on the injury mechanism of vascular endothelial cells in atherosclerosis.Methods The latest progress was reviewed in recent literatures.Results All kinds of etiological factors have activated NF kappa B and cytokines in the development of atherosclerosis, which lead to expression of cell adhesive molecules and adhesion of monocytes to vascular endothelial cells.A variety of inflammatory mediums are released, which can directly damage endothelial cells.Besides, the inflammatory mediums make monocytes and neutrophils attach to endothelial cells by immune mechanisms, which injure the endothelial cells more severely. Meanwhile the damaged membrance structure leads to the production of AECA which activates the complementary system. Then the vascular endothelial cell injury is aggravated and the development of atherosclerosis accelerated. Conclusion It is very important to recognize the injury mechanism of vascular endothelial cells in the development of atherosclerosis for prevention and treatment of atherosclerosis.

Objective To explore the inchoate changes in patients with Graves disease (GD) treated with 131I and appraise the therapeutic effect. Methods According to the thyroid size, patients’ age, thyroid 131I intake rate and course of the disease, 303 patients with GD were given individual 131I doses. Six months later, the symptom, signs, and thyroid hormone levels of every case were compared with those recorded before. Results The symptom and the level of thyroid hormones were significantly meliorated after 131I treatment. Six cases became goggle-eyed after treatment. Among the 303 patients, 249(82.18%) fully recovered, 21 (6.93%) partially remitted, 24(7.92%) developed hypothyroidism, and 9(2.97%) showed ineffective. Conclusion 131I treatment for GD with an individual dose can exert a satisfied therapeutic efficacy. It may as serve the first choice for GD treatment.

Objective To evaluate the effects of pulmonary recruitment (RM) in severe acute respiratory distress syndrome (ARDS) with different body position and positive end-expiratory pressure (PEEP) mode in stage of mechanical ventilation. Methods From June 2013 to June 2016, 80 cases of ICU hospitalized patients with clinical data were enrolled, and they lay in the prone or supine position (prone position group and supine position group, each of 40 cases). The hemodynamic parameters including heart rate (HR), central venous pressure (CVP) and peripheral arterial pressure, respiratory mechanics index including respiratory rate (RR), respiratory system compliance (Crs) and platform pressure (Pplate), and the changes of blood gas analysis index were monitored to observe the effects of RM in different positions with positive end expiratory pressure increasing method. Results The levels of oxygenation index and arterial partial pressure of oxygen (PaO2) were improved 3, 5 and 7 d after treatment compared with those 1 d after treatment (P<0.05), and they were improved significantly in prone position group than those in supine position group 3 and 5 d after treatment (P<0.05). The levels of RR, Crs and Pplate 15 min, 30 min, 1 h, 6 h, 12 h and 24 h after RM had significant differences compared with those before RM (P<0.01). The levels of HR, CVP, peripheral arterial pressure 15 min, 30 min, 1 h, 6 h, 12 h and 24 h after RM had no significant differences compared with those before RM (P>0.05). Conclusions For patients with severe ARDS, early implementation of prone position ventilation combined with PEEP increasing method re-expansion treatment is safe and reliable. It can effectively improve oxygenation level and help to improve the survival rate.
