ABSTRACT
There are various etiologies for extrahepatic bile duct stenosis， and pharmacotherapy and endoscopic intervention can achieve a good clinical effect in benign stenosis. Early diagnosis and timely surgical treatment of malignant stenosis may prolong the survival time of patients. However， there are still difficulties in the differential diagnosis of malignant bile duct stenosis. This article reviews the application of serology， radiology， endoscopic techniques， and artificial intelligence in the differential diagnosis of malignant bile duct stenosis， so as to provide strategies and references for formulating clinical diagnosis and treatment regimens.
ABSTRACT
Cadmium sulfide nanoparticles are a new type of semiconductor nanomaterials used in many applications. Studies have shown that cadmium sulfide nanoparticles have toxic effects on the reproductive system， liver， and kidney of the body， and the toxicities are affected by various factors. This paper summarized the current research on the toxicity of cadmium sulfide nanoparticles at home and abroad， and reviewed the latest research progress on the mechanisms of its toxic effects and influencing factors.
ABSTRACT
Objective To evaluate the safety and feasibility of totally laparoscopic radical distal gastrectomy (TLDG)and intracorporeal gastroduodenostomy using laparoscopic linear staplers in gastric cancer patients.Methods Clinical data were reviewed on the perioperative outcomes of 17 gastric cancer patients who received totally laparoscopic distal gastrectomy and intracorporeal gastroduodenostomy using endoscopic linear staplers from June 2012 to June 2013 at Department of General Surgery,Lishui Central Hospital.Results The mean operation time were (2.6 ± 0.4) h,TLDG with deltashaped anastomosis was successfully carried out in all the patients except for 1 case who was converted to open surgery.There was no serious complication and no death in this series.The postoperative pain in TLDG was less than laparoscopy assisted distal gastrectomy.Conclusions Totally laparoscopic distal gastrectomy and intracorporeal gastroduodenostomy using endoscopic linear staplers is a new method with high safety and feasibility.
ABSTRACT
There have been problems in the existing multiple physiological parameter real-time monitoring system, such as insufficient server capacity for physiological data storage and analysis so that data consistency can not be guaranteed, poor performance in real-time, and other issues caused by the growing scale of data. We therefore pro posed a new solution which was with multiple physiological parameters and could calculate clustered background data storage and processing based on cloud computing. Through our studies, a batch processing for longitudinal analysis of patients' historical data was introduced. The process included the resource virtualization of IaaS layer for cloud platform, the construction of real-time computing platform of PaaS layer, the reception and analysis of data stream of SaaS layer, and the bottleneck problem of multi-parameter data transmission, etc. The results were to achieve in real-time physiological information transmission, storage and analysis of a large amount of data. The simulation test results showed that the remote multiple physiological parameter monitoring system based on cloud platform had obvious advantages in processing time and load balancing over the traditional server model. This architecture solved the problems including long turnaround time, poor performance of real-time analysis, lack of extensibility and other issues, which exist in the traditional remote medical services. Technical support was provided in order to facilitate a "wearable wireless sensor plus mobile wireless transmission plus cloud computing service" mode moving towards home health monitoring for multiple physiological parameter wireless monitoring.

Objective To explore the use of urine LH test paper associating basal body temperature in ovulation monitoring and conception guiding in anovulatory infertility.Methods We used clomiphene to treat 100 anovulatory infertility patients.Then we recorded basal body temperature and used urine LH test paper in morning to determine whethere there is urine LH peak between the 12th to 20th day of menstrual cycle.If the patient become pregnant,we stop observation.If not,we observed them until the third treatment cycle completed.Result Before treatment,both the urine LH test paper and basal body temperature showed there was no ovulation.After treatmend,we observed 199 menstrual cycle.There were urine LH peak in 149 menstrual cycle.And there were double phase body temperature in 158 treat cycle.The lowest body temperature appeared in the urine LH peak day or after it.71.1%of the lowest body temperature emerged in one or two days after the urine LH peak appeared.76 patients in our study become pregnant,pregnancy rate is 76%.Conclusion Urine LH test paper associating basal body temperature is convenient and easy tO learn.It is a good way in ovulation monitoring and conception guiding.
ABSTRACT
Objective To explore the sexual life quality of females at the reproductive ages after cervix cancer operation and supply evidence for establishment of correspondindg nursing measure. Methods We investigated the frequency of sexual life and satisfaction degree of sexual life in 40 females at the reproductive ages after cervix cancer operation by face-to-face investigations using questionnaires before and 4 months after operations. Then the difference of sexual life quality before and after operation were compared and analyzed. Results The frequency of sexual life (P＜0.01,P＜0.05) and satisfaction degree of sexual life (P＜0.01,P＜0.05) were evidently decreased. The sexual life quality was lower than that before operation. Conclusion The sexual life quality could be affected by many factors such as economic conditions, culture background, sexual conceptions and the attitude of their partners.
