目的 探讨CD117在肺基底样细胞鳞状细胞癌(BSCC)与小细胞肺癌(SCLC)中的鉴别诊断作用。方法 免疫组织化学检测CD117在肺BSCC与SCLC中的表达情况,并进行统计学分析,同时文献复习CD117在这两种肿瘤中的表达情况。结果 CD117在SCLC中特异性高表达(阳性率为78%),并且具有高的敏感度、特异度、阳性预测值及阴性预测值(分别为100%、78.2%、68.7%、100%),与文献报道一致(阳性率37%～100%);而在BSCC中未见有CD117的表达,文献未见有CD117在BSCC中表达情况报道。结论 CD117有可能成为鉴别诊断BSCC与SCLC的重要指标之一。但由于本报道例数有限,还需要更大型的研究进一步证明CD117在鉴别诊断二者中的敏感度及特异度。

Objective To investigate the role of CD117 in differentiating basaloid squamous cell carcinoma (BSCC) from small cell carcinoma (SCLC) in lung. Methods Immunohistochemistry staining of CD117 and statistic data were analyzed in BSCC and SCLC, and relevant literature were reviewed. Results CD117 was specifically expressed in high level ( positive rate 78%) in SCLC with high sensitivity, specificity, positive predictive value and negative predictive value (respectively 100%、78.2%、68.7%、100%), which was highly consistent with literature reports (positive rate 37%-100%). CD117 was not detected in BSCC in our report and it was the same as in literatures. Conclusion Although our results showed that it was possible that the expression of CD117 would play an important role in differentiating BSCC from SCLC, due to limited cases in number, more studies are needed to elucidated the sensitivity and specificity.

Objective To investigate the correlation between the growth rate, thyroid function in the first month and neurodevelopmental outcome at the age of 2 in the infants of the maternal thyroid disease. Methods We chose 156 infants of maternal thyroid disease from January 2013 to December 2014 born in our hospital as the experimental group and 150 normal infants of their mothers without high risk factors during pregnancy as the control group. We observed the rate of weight, length and head circumference growth in the first month and TT4 、TSH level at the 1^st day, 7^th day, and 28^th day after birth. We followed up two groups every 3 months up to the age of 2. We assessed Bailey mental development index (MDI) and psychomotor development index (PDI) at the age of 2. Regression analysis was used to test the correlation between the growth rate, TT4,TSH level in the 1^st month and MDI, PDI at the age of 2. Results ① The rate of growth rate in the 1^st month of the experimental group was slower than the control group. It was statistically significant difference between the two groups (P<0.05); ②MDI, PDI at the age of 2 in the experimental group were lower than those of the control group. It was statistically significant difference between the two groups (P<0.05); ③The rate of growth rate in the first month of the experimental group was positively related to MDI and PDI at the age of 2.④The difference between the level of TT4,TSH at the 1^st day, 7thday, and 28^th day and the median after birth was negatively related to MDI and PDI at the age of 2. Conclusion The maternal thyroid disease will affect the first month growth rate and neurodevelopmental outcome at the age of 2 of their infants. Their infants will grow behind than the normal newborns on pregnancy without high-risk disease.The growth rate of the first month and the level of T4 and TSH on the 1^st day, 7^th day, and 28^th day in maternal thyroid disease are closely related MDI and PDI at the age of 2.

Objective To assess the safety and efficiency of combination of micro incision phacoemulsification (PHACO) surgery and intravitreal ranibizumab injection in patients with cataract and diabetic macular edema. Methods The selected 68 patients (72 eyes) with age-related cataract and diabetic macular edema were randomly divided into two groups: the PHACO and intravitreal Ranibizumab injection (treatment group, 32 cases, 34 eyes), and only PHACO (control group, 36 cases, 38 eyes) in our hospital from July 2014 to November 2016. Preoperative and postoperative best corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure (IOP) were recorded. The time points included preoperative day, 1 week, 1 month, 3 months, 6 months and 12months after surgery. Results Postoperative BCVA during the follow-up period was higher than the initial BCVA in both groups (P<0.01). There was no statistically significant difference between both groups in BCVA at pre-operation and 1 week after surgery. In the treatment group, the postoperative BCVA was significantly higher than the control group at 1 month, 3 months, 6 months and 12months after operation. The mean CMT in the treatment group was lower than the control group in all the follow-up time. There was no statistically significant difference in IOP between two groups preoperatively and postoperatively during the follow-up period (P>0.05). Conclusion Additional intravitreal ranibizumab injection after PHACO surgery reduced macular edema and preserved this improvement in the mid-and-long term of BCVA.

Objective To explore evaluation value of alkaline phosphatase in vascular calcification and osteoporosis in maintenance dialysis patients. Methods 186 patients in maintenance dialysis were enrolled in this study. The related clinical data was recorded. The examination of X-ray (lateral abdomens) was done to estimate vascular calcification in patients. Bone mineral density was measured by dual energy X-ray absorptiometry. The results above were analyzed by bivariate correlation analysis and receiver operator characteristic curve. Results By bivariate correlation analysis,serum alkaline phosphatase level was negatively associated with femoral neck bone mineral density, and was positively associated with abdominal aortas calcification scores. Abdominal aortas calcification scores were negatively associated with femoral neck bone mineral density. ROC curve revealed AUCs were respectively 0.777 and 0.701 for serum alkaline phosphatase level in diagnosis of osteoporosis and severe abdominal aortas calcification. Conclusion Alkaline phosphatase may be a good index to evaluate calcification and osteoporosis in maintenance dialysis patients.
