ABSTRACT
The use of non-invasive blood glucose detection techniques can help diabetic patients to alleviate the pain of intrusive detection, reduce the cost of detection, and achieve real-time monitoring and effective control of blood glucose. Given the existing limitations of the minimally invasive or invasive blood glucose detection methods, such as low detection accuracy, high cost and complex operation, and the laser source's wavelength and cost, this paper, based on the non-invasive blood glucose detector developed by the research group, designs a non-invasive blood glucose detection method. It is founded on dual-wavelength near-infrared light diffuse reflection by using the 1 550 nm near-infrared light as measuring light to collect blood glucose information and the 1 310 nm near-infrared light as reference light to remove the effects of water molecules in the blood. Fourteen volunteers were recruited for

Objective To investigate the clinical curative effect of the exceed -calcaneocuboid -joint plate in the treatment of Sanders Ⅲ/Ⅳ calcaneal fracture .Methods 58 cases ( 67 feet ) with Sanders Ⅲ/Ⅳ calcaneal fractures were selected .The patients were followed up for 1 year postoperation .The patients′age,fracture classification , Maryland foot score,complications,and postoperative 1 day,postoperative 1 year B?hler corner,Gissane angle,height, and length of the calcaneus were recorded .Results The preoperative B?hler corner,Gissane angle,height and length of calcaneus were (7.9 ±4.2)°,(85.2 ±6.9)°,(30.6 ±2.6) mm,(65.5 ±2.1) mm,respectively,which of postoperative 1 day were (31.8 ±4.7)°,(128.6 ±8.1)°,(43.7 ±2.3)mm,(70.3 ±2.6)mm,respectively,which of postoperative 1 year were (31.9 ±4.8)°,(128.7 ±7.7)°,(43.5 ±2.1) mm,(70.2 ±2.8) mm,respectively. Compared with preoperation ,the postoperative data were significantly improved , and the differences were statistically significant(postoperative 1 day compared with preoperation:t=7.13,3.59,4.14,6.95,postoperative 1 year compared with preoperation:t=8.76,3.92,5.02,7.17,all P<0.05).The excellent rate in exceed -calcaneocuboid -joint plate group was 91.04％.Conclusion Using exceed-calcaneocuboid-joint plate internal fixation for Sanders Ⅲ/Ⅳ calcaneal fractures , can significantly improve the prognosis of patients and better restore height and length of the calcaneus ,it is worthy of clinical application .
ABSTRACT
Objective To analyze the population distribution and clinical characteristics of esophageal cancer in Luzhou prefecture of Sichuan. Methods The data of 690 cases of resected specimens with esophageal cancer from October 2010 to September 2014 were analyzed retrospectively, including 659 cases of esophageal squamous cell carcinoma, 10 cases of adenocarcinoma, 7 cases of adenosquamous carcinoma, 5 cases of sarcomatoid carcinoma, 2 cases of carcinoma in situ, 3 cases of leiomyosarcoma, 2 cases of small cell carcinoma, 1 case of undifferentiated carcinoma and 1 case of mixed carcinoma. Results The constituent ratio of 51-60 years old population of 690 cases with esophageal cancer was the highest for 40.00%(276/690). In≤60 years patients, the rate of esophageal cancer in male was higher than that in female: 56.15%(338/602) vs. 34.09%(30/88), χ2 = 15.005, P =0.000. Clinical pathological factors of lymph node metastasis showed that there were statistically significant differences between male and female: 45.68%(275/602) vs. 34.09%(30/88), χ2 = 4.182, P =0.041;the lower the position, the higher the lymph nodes metastasis rate:the lymph nodes metastasis rate in superior segment, middle segment, inferior segment was 32.00%(8/25), 41.22%(216/524) and 57.45%(81/141),χ2=13.425, P=0.001;the lower the differentiation, the higher the lymph nodes metastasis rate:the lymph nodes metastasis rate in high, middle and lower differentiation was 40.84%(165/404), 47.60%(109/229) and 75.76%(25/33), χ2 = 16.065, P = 0.000. The lymph nodes metastasis rate in different general types and histology types had no significant differences(P>0.05). Conclusions The incidence rate of esophageal cancer in male is significantly higher than that in female, the higher the lymph node metastasis rate, the lower the position and the differentiation of esophageal cancer in Luzhou prefecture of Sichuan.
ABSTRACT
Objective To analyze the value of fine needle aspiration for male breast cancer and to investigate the clinical characteristics of male breast cancer.Methods The cell morphological characteristics of fine needle aspi-ration and clinical data were analyzed retrospectively within a total of 35 cases with male breast cancer of Affiliated Hospital of Luzhou Medical College,from 2000 January to 2014 December.Results During the 35 patients of male breast cancer with fine needle aspiration,from 35 to 82 years old,the median age was 64 years old and mean age was 61.6 years old.There were 23 cases of male breast cancer from 60~82 years old,suggesting that the relatively high incidence was after the age of 60 years.The diameter of male breast tumor was 0.8~8cm,while the average diameter was 3.5cm.In the clinical stage of TNM,14 cases were with stageⅠ,13 cases were with stageⅡ,7 cases were with stage Ⅲand 1 case wasⅣstage;that was to say,the cases of male breast cancer in the late was relatively more.The invasive ductal cancers were 16 cases (45.7%) of male breast cancer.The sensitivity was 94.3% of fine needle aspiration cytology before the operation.Conclusion The accuracy of fine needle aspiration cytology has important significance for the diagnosis of male breast cancer,can be used as a mean of detecting male breast tumor as benign or malignant.
