Objective To analyze the changes of drug resistance of Pseudomonas aeruginosa (Pae) and to provide basis for the use of antibiotics in clinic. Methods 2 257 strains of Pae were cultured and isolated in the First People Hospitalof Guangzhou from 2011 to 2016, API bacterial identification system was applied to carry out bacterial identification and K-B method was used for drug sensitivity analysis. Results Most of the Pae (56.9％) were detected from the sputum specimen. It showed the highest sensitivity to tobramycin. The drug resistance of Pae to piperacillin/tazobactam, cefepime, ceftazidime, levofloxacin, ciprofloxacin, imipenem and gentamicin in 2013 was the lowest and has been increasing year by year. Conclusion Pseudomonas aeruginosa isolated in our hospital showed a rising trend of clinical drug resistance in the past three years. It was of the top priority for clinicians to use antibiotics rationally to retard the production of drug resistant strains.

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 analysis and summary clinical characteristics of 15 patients who were diagnosed with abdominal pregnancy,which supply reference for clinical work. Methods 15 cases who were diagnosed with abdominal pregnancy and admitted to Guangdong Women and Children hospital between January 2002 and June 2018 were identified. Retrospective analysis was used to summarize the clinical characteristics of diagnosis and treatment in 15 patients. Test statistics used Student's t test to find if there was statistical difference between laparoscopic and abdominal surgery patients in perioperative period. Results One case was likely diagnosed with greater omentum pregnancy by type B ultrasound. Another one patient was diagnosed with abdominal pregnancy which has 8+ weeks pregnant single live fetus by type B ultrasound in other hospital prior to hospitalization.The B ultrasound tests of the other 13 patients showed there were no sac in uterus and enclosed mass beside uterus which were diagnosed with ectopic pregnancy, but not positive diagnosis with abdominal pregnancy.Surgery was performed for 14 patients.We found more different sites where gestational sacs plant in abdominal pregnancy patients in operation, 5 cases sacs planted in greater omentum, 9 cases sacs planted in pelvic cavity including 1 case sac planted in pelvic wall bottom-right bladder,1 case sac planted in rectum outside right-hand of Douglas pouch,2 cases sacs planted in right utero-sacral ligament,1 case sac planted in right-side of scar in lower uterus segment,1 case sac planted in adhesive tissue between the lift intestinal canal and uterus,1 case sac planted in right pelvic cavity,1 case sac planted in Douglas pouch,1 case sac planted in initiating terminal of the lift round ligament of uterus. The inteventional puncture with medical treatment was supply for only 1 patient,CT test showed the sac planted in abdominal: ahead of third lumbar vertebra between abdominal aorta and inferior vena cava. Conclusion There are more sites where gestational sacs can plant in abdominal pregnancy patients. Ultrasound is first choice for patient who was considered ectopic pregnancy and better to expansion the inspection range. MRI or CT may find sacs plant site who was considered abdominal pregnancy which may reduce missed diagnosis and misdiagnosis. Surgery is first performed who was diagnosed with abdominal pregnancy. Medical treatment for patients who vital signs are stable.

Objective To understand the health status of retired people in a government agency in Nanchang city,and to provide evidence for the prevention and treatment of diseases. Methods According to the routine physical examination items of the department of physical examination of Nanchang university hospital,the health examination of retired staffs of a government agency in Nanchang city from 2016 to 2018 was carried out. The proportion of abnormal physical examination was analyzed,and the rate of two samples was compared by χ² test. Results Abdominal ultrasound,thyroid ultrasound,blood lipid,helicobacter pylori （HP）,electrocardiogram,liver and kidney function,cervical scraper and leucorrhea （female）,blood sugar,tumor index were the main abnormal indexes. The abnormal rate of color Doppler ultrasound was as high as 82.98% and 82.95%,respectively. The proportions of benign prostatic hyperplasia,fatty liver and abnormal biliary system were higher in the patients with abnormal abdominal color Doppler ultrasound. The abnormal rate of abdominal color Doppler ultrasound was higher in male than that in female,and the abnormal rate of thyroid ultrasound and tumor index were higher in female than that in male （P< 0.05）. Conclusion The proportions of abnormal health examination indexes of retired staffs in this government agency are relatively high. It is necessary to establish a health record database for health management,and arrange periodic reexamination for those who have abnormal physical examination indexes in order to realize importance of early detection and early diagnosis of diseases,and have early treatment.

目的 在原来研究的基础上进一步研究Wnt-1信号通路蛋白-3（WISP-3）在高氧诱导肺上皮细胞凋亡中的作用。方法 通过Western blot检测和免疫组化检测不同肺上皮细胞中WISP-3的蛋白表达量。利用质粒转染和siRNA的方法在Beas-2B细胞中高表达和基因沉默WISP-3,通过细胞活性检测和流式细胞学技术检测高氧刺激后细胞的凋亡情况。结果 与空气对照相比,高氧刺激使肺上皮细胞的WISP-3蛋白表达量下降;WISP-3基因沉默或高表达使高氧诱导的肺上皮细胞凋亡增加或减少。结论 高氧刺激下,肺上皮细胞中WISP-3表达下降,WISP-3对高氧诱导的肺上皮细胞凋亡具有保护作用。

Objective To explore how Wnt-1 inducible signaling pathway protein-3 （WISP-3） participate in and play a regulatory role in the process of hyperoxia induced apoptosis in lung epithelial cells. Methods The expression of WISP-3 was detected via Western blot and immunohistochemistry. High expression and low expression of WISP-3 were performed by plasmid transfection and siRNA. Cell viability and flow cytometry were executed to detect the hyperoxia-induced apoptosis in Beas-2B. Results Compared to the group of air control,the expression of WISP-3 protein in lung epithelial cells decreased obviously after hyperoxia. Cell survival decrease and apoptosis increased after hyperoxia in Beas-2B cells with low expression of WISP-3. Vice versa. Conclusion The expression of WISP-3 decreased after hyperoxia in lung epithelial cells. The role of WISP-3 in this process may be protective.
