Objective To analyze the value of middle ear endoscopy in patients with middle ear cholesteatoma. Methods The clinical data of 61 patients with unilateral middle ear cholesteatoma were retrospectively analyzed. All of them underwent surgery. Among them, 31 underwent otoendoscopic surgery, which was recorded as group A; 30 underwent conventional tympanoplasty, which was recorded as group B. The changes of air-bone conduction, airway auditory threshold, clinical effect and complications were compared between the two groups before and 1 month after operation. Results One month after operation, the difference of air-bone conduction and airway auditory threshold in group A were (8.5±1.5) dB and (21.2 ±2.4) dB, were lower than those before operation (t=38.195, P<0.001;t= 27.739,P<0.001), group B were (13.4±2.3) dB and (25.6±2.7) dB, respectively, lower than those before operation (t= 23.510,P<0.001;t=21.575,P<0.001), one month later, the air-bone conduction and airway hearing threshold in group A were lower than those in group B (t=9.888,P=0.000;t=6.732,P<0.001); The difference was statistically significant in clinical effect distribution between group A and group B (Z=6.102,P= 0.014), and the total effective rate of group A was 100.00%, which was higher than that of group B 83.33% (χ²= 5.628,P=0.018); the total incidence of complications in group A was 3.23%, lower than that in group B 20.00% (χ²= 4.223,P=0.040). Conclusion Endoscopic ear surgery may improve the air-bone conduction and airway auditory threshold in patients with middle ear cholesteatoma, which is more effective and safe than conventional tympanoplasty.

目的 探讨磁共振磁敏感加权成像(SWI)对脑膜、脑转移瘤的诊断价值。方法 随机选取2016年3月—2018年3月我院收治的经临床、病理确诊的50例脑膜、脑转移瘤患者为研究对象,所有患者除常规行T1WI、T2WI扫描及T1WI增强扫描检查外,额外进行SWI检查。观察不同来源脑转移瘤转移部位、肿瘤实质信号在不同成像序列上的特征及对瘤内血管情况和出血状况的判断。结果 脑转移瘤的发生部位多为顶叶(29.75%)和枕叶(20.66%),就血供区域而言,多发生于中动脉(45.45%)和颈内动脉供血区域(38.02%)。不同MRI成像序列中肿瘤信号特征比较,显示均有差异(P<0.001)。其中,肺癌脑转移瘤T1WI呈低信号(62.96%),胃癌T2WI呈现高信号(68.75%),SWI成像序列上多显示为混杂信号。SWI序列成像显示瘤内出血55例(45.45%),显示引流血管16条,瘤内出血及肿瘤血管检出率均明显高于T1WI平扫检查,差异有统计学意义(P<0.05)。结论 不同来源的脑转移瘤MR的表现不同,为逆向推测脑转移瘤来源提供依据,同时SWI是对常规序列的重要补充,尤其是在脑瘤出血和血管检出上有重要作用,值得临床推广使用。

Objective To investigate the diagnostic value of susceptibility-weighted imaging(SWI) in meningiomas and brain metastases. Methods 50 cases of clinically and pathologically confirmed patients with meningioma and brain metastasis admitted to our hospital from March 2016 to March 2018 were randomly selected as the study subjects. All patients received routine T1WI, T2WI scan and T1WI enhanced scan, and additional SWI examination was performed. We observed the characteristics of metastatic sites and tumor parenchymal signals in different imaging sequences of brain metastatic tumors from different sources and to judge the status of intramedullary blood vessels and bleeding. Results The majority of brain metastatic tumors occurred in the parietal lobe (29.75%) and occipital lobe (20.66%). In terms of the blood supply region, the majority occurred in the middle artery (45.45%) and the blood supply region of the lower artery (38.02%). Comparison of tumor signal characteristics in different MRI imaging sequences showed differences, P<0.001. Among them, T1WI of brain metastatic tumor of lung cancer presented significantly low signal (62.96%), T2WI of gastric cancer presented high signal (68.75%), and SWI imaging sequence mostly showed mixed signal.SWI sequence imaging were showed in 55 cases (45.45%) of intracranial hemorrhage and 16 drainage vessels. The detection rate of intracranial hemorrhage and tumor blood vessels was higher than that of T1WI plain scan, with statistically difference (P<0.05). Conclusion MR manifestations of brain metastatic tumors from different sources are different, providing a basis for reverse speculation of the source of brain metastatic tumors. At the same time, SWI is an important supplement to routine sequences, especially in the hemorrhage of brain tumors and the detection of blood vessels, which is worthy of clinical promotion and use.

目的 本研究以ICSI后未成熟卵母细胞为研究对象,分析比较卵母细胞不同发育阶段冷冻对其后续效果的影响,评估ICSI后未成熟卵母细胞的利用价值。方法 未成熟卵母细胞直接成熟培养(新鲜组)与玻璃化冷冻后成熟培养(冷冻组)的成熟率,并利用孤雌激活的方法比较卵母细胞的发育潜力。结果 发现新鲜组与冷冻组体外培养卵母细胞成熟率、受精率、卵裂率、优质胚胎率和囊胚率均无差异(P>0.05)。但两组的GV期卵母细胞成熟率低于MI期(P<0.05),且冷冻组的GV期卵母细胞受精率低于MI期(P<0.05)。不过裸卵体外成熟培养效果欠佳,特别是对GV期卵母细胞,体外成熟培养后的卵母细胞发育潜力低下,无囊胚形成。结论 ICSI后未成熟卵母细胞的冷冻对卵母细胞的发育潜力没有明显影响,但体外成熟培养的卵母细胞发育潜力低下,有待进一步提高体外成熟培养技术。

Objective In this study, the immature oocytes after ICSI were used to analyze the effects of freezing on the subsequent development of oocytes at different developmental stages, and to evaluate the utilization value of immature oocytes after ICSI(intracytoplasmic sperm injection). Methods The immature oocytes was directly cultured (fresh group) and matured after vitrification (frozen group), and the development potential of the oocytes was compared by parthenogenetic activation. Results There was no significant difference in the oocyte maturation rate, fertilization rate, embryo cleavage rate, high quality embryo rate and blastocyst rate between the fresh and frozen groups (P>0.05). However, the maturation rate of GV oocytes in the two groups was lower than MI oocytes (P<0.05), and the fertilization rate of GV oocytes in the frozen group was lower than MI oocytes (P<0.05). However, the in vitro maturation of naked oocytes was not effective, especially for GV oocytes, the oocyte development potential after in vitro maturation was low, there was no blastocyst formation. Conclusion The freezing of immature oocytes after ICSI has no significant effect on the development potential, but the development potential of naked oocytes matured in vitro was low, and the in vitro maturation culture technology of naked oocyte needs to be further improved.

Objective To predict the osteoporotic fracture risk in senile people in Guangzhou communities by FRAX,the fracture risk assessment tool published by WHO. Methods Clinical data of 1140 cases were collected for the retrospective analysis. The FRAX tool was uesed to calculate the 10-year probability of a major osteoporotic and hip fracture.The relationship between different risk factors and the fracture risk predicted by FRAX was analyzed.

Objective To investigate the effect on intestinal mucosal barrier dysfunction (IBF) of Xuebijing injection mediated by Toll-like receptor 4 (TLR4) signal pathway in rats of severe acute pancreatitis (SAP). Methods 24 Sprague Dawley (SD) rats were randomly divided into Sham group (n=8), control group (n=8) and treatment group (n=8). The SAP model was established by retrograde injection of 4.5% sodium taurocholate into the biliopancreatic duct in control group and treatment group, while control group was injected with the same amount of saline. In treatment group, Xuebijing injection (3 mL/kg) was injected via tail vein after 3h of modeling. All rats were monitored and sacrificed after 24 hours of modeling. Samples of pancreas and intestine were collected for pathologic determination. A fluorescent RT-PCR was used to determine the expression of TLR4 and NF-κB of small intestine. The serum levels of TNF-α, IL-6, amylase (AMS) and diamine oxidase (DAO) were measured by using ELISA. All parameters of three groups were compared. Results The expression of TLR4 and NF-κB of small intestine in control group and treatment group were higher than it in control group (P<0.05), as well as the serum levels of TNF-α, IL-6, AMS and DAO (P<0.05). The expression of TLR4 and NF-κB of small intestine in treatment group were lower than it in control group (P<0.05), as well as the serum levels of TNF-α, IL-6, AMS and DAO (P<0.05). Conclusion Xuebijing injection may not only reduce the expression of TLR4 and NF-κB of small intestine, but also alleviate the inflammation reaction of small intestine by interfering with TLR4 signal pathway, which may have a protective effect on intestinal mucosal barrier in SAP rats.
