Abstract: Schistosomiasis, an important zoonotic parasitic disease, is one of the six major tropical diseases identified by WHO, and also one of the most important parasitic diseases for prevention and control in China. After more than 70 years of efforts, the prevention and control of schistosomiasis in China has made great achievements, and the current epidemic of schistosomiasis in China has entered an extremely low epidemic state, but the distribution base of the only intermediate host of schistosomiasis, Oncomelania hupensis, is still large. For now, the techniques used to monitor schistosomiasis have shortcomings such as time-consuming, laborious and low sensitivity, which cannot meet the current needs of China. Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water or air) without isolating any target organisms, which is a complex mixture of genomic DNA and its degradation products from different organisms in the same environment. eDNA technology can reflect the community or species composition information in the ecosystem through DNA extraction and detection of environmental samples. Compared with traditional biological monitoring methods, eDNA technology has the advantages of high efficiency, high sensitivity and environmental friendliness. eDNA has been successfully used for the specific detection of Schistosoma mansoni, Schistosoma haematobium and Schistosoma japonicum. This paper reviews the current detection methods of eDNA, the application and technical limitations of eDNA technology in schistosomiasis monitoring, aiming to provide scientific reference for research in the field of schistosomiasis surveillance.

Objective To understand the epidemiological distribution and epidemic situation of brucellosis cases in Zhejiang Province in 2003 - 2012. Methods Questionnaires of confirmed brucellosis cases, annual reports of prevention and control work of brucellosis in the cities and monitoring points were collected and analyzed in 2003 - 2012. Population distribution, regional distribution, infection sources and routes of infection, aetiology and clinical symptoms and signs of the brucellosis cases were analyzed descriptively. Results A total of 323 brucellosis cases were reported in 2003 - 2012, the average annual incidence rate was 0.070/one hundred thousand, the incidence rate in 2012(0.190/one hundred thousand) was high. There were 272 people of the 323 brucellosis cases were from occupational populations, accounting for 84.21%(272/323); people worked in buying, slaughtering and trafficking of livestock products were majority of the cases, accounting for 65.02%(210/323); and unoccupational population was accounting for 15.79%(51/323). Regional distribution of brucellosis was gradually spreading; the average incidence rate of Shaoxing City was the highest ( 0 . 226/one hundred thousand ) . Three hundred patients were infected by sheep, accounting for 92.88%(300/323), and only 7.12%(23/323) of the patients were infected by cattle. Two hundred and eighty-seven acute phase patients of brucellosis were checked by blood culture, and thirty-nine Brucella melitensis strains and two Brucella abortus strains were detected. The chronicity survey of 120 confirmed cases of brucellosis were conducted, chronicity rate was 3.33%(4/120). Conclusions Trends in the epidemic situation of brucellosis in Zhejiang Province has continued to spread. The main source of infection is sheep from the North. Occupational populations are major populations at risk. The key of prevention and control is to strengthen the active monitoring of occupation personnel , health education and behavior intervention.

Objective To explore the effect of a multimodal electroencephalogram ( EEG) data visualiza-tion system on the motor imagery ability of stroke survivors. Methods Twenty stroke patients were randomly di-vided into an experimental group and a control group, each of 10. Both groups were provided with brain-computer interface-based motor imagery ( MI) training. At the same time, the experimental group was monitored and guided using an online, multimodal EEG data visualization system developed in our department. The classification accuracy ( CA) and event-related desynchronization ( ERD) of the 2 groups′ motor imagery were compared before and after the treatment. Results Before the treatment, no significant differences in the average CA of MI were found be-tween the experiment group (50.92±2.08) and the control group (49.35±4.20)(P>0.05). After the treatment, however, the experimental group′s average CA had increased to (64.52±5.27), significantly higher than that of the control group (51.18±5.02). When the stroke patients imaged affected upper extremity movements, obvious ERD was observed in the α frequency around the bilateral central motor regions of both groups, especially in the experi-mental group, but without significant differences between the two groups. However, no significant changes were found in the ERD of theβwaves of the two groups( P>0.05) . Conclusion The proposed online multimodal elec-troencephalogram data visualization system can help stroke patients imagine movements actively. It is worth sprea-ding in clinical practice.

BACKGROUND:Mirror therapy was initial y used in the treatment of affected limb pain after amputation, and has been applied as a valid way for relieving complex regional pain syndrome due to other injuries, but the efficacy for patients with upper limb complex regional pain syndrome (type II) more than 3 years after high-level spinal cord injury has not been reported in any way.
OBJECTIVE:To investigate the availability of mirror therapy for reducing pain in a patient with upper limb complex regional pain syndrome (type II) who suffered high-level spinal cord injury.
METHODS:An experimental design of self cross-control was applied for al eviating the patient’s pain with the intervention of transcutaneous electrical nerve stimulation and mirror box therapy, which were conducted 2 or 3 weeks respectively. And the elution period between two kinds of treatments was 1 week, the fol ow-up time was 1 month.
RESULTS AND CONCLUSION:The pain of the patient was not relieved, but even aggravated after 2 weeks of transcutaneous electrical nerve stimulation, while 3-week mirror box therapy significantly reduced the pain after elution period (the third week). The Hamilton anxiety scale, Hamilton depression scale, and WHO quality of life scale scores were significantly improved after treatment compared with before treatment. Experimental findings indicate that, mirror therapy may be an effective intervention for mitigating complex regional pain syndrome (type II) in addition to the comprehensive treatments, but further studies are warranted to confirm its effect.

To analyze the composition regularity of prescriptions containing Scutellaria baicalensis in Drug Standard of Ministry of Public Health of the Peoples Republic of China--Chinese Patent Medicines and Preparations on the basis of the traditional Chinese medicine inheritance support system (TCMISS), in order to provide reference for new drug R&D. the platform's software V2.0 was applied to establish a database of prescriptions containing S. baicalensis. The software's statistical statement module, association rules and improved mutual information method and other data mining technologies were adopted to analyze commonly used drugs, combination rules and core combination of S. baicalensis prescriptions. Having analyzed 477 prescriptions containing S. baicalensis, the researchers summarized 45 most commonly used drug combinations, whose ingredients mostly had functions of heat-clearing and damp-drying, purging fire for removing toxin and hemostasis. Drugs adopted in core combinations were relatively concentrated and selected according to definite composition methods. There were 23 diseases that S. baicalensis were most frequently applied in the treatment. Having compared three highly frequent diseases--cold, cough and dizziness, the researchers concluded that S. baicalensis could show different therapeutic effects through different combination ratios. Therefore, TCMISS (V2.0) is an important tool in analyzing the composition regularity of traditional Chinese medicines. The longitudinal and parallel comparison method is an effective method for studying the clinical composition regularity of S. baicalensis, while providing reference for new drug R&D.

OBJECTIVETo investigate the clinical application of the ureteral dilation catheter combined with the balloon catheter under the ureteroscope in the treatment of urethral stricture in men.

METHODSUnder the ureteroscope, 45 male patients with urethral stricture received placement of a zebra guide wire through the strictured urethra into the bladder and then a ureteral dilation catheter along the guide wire, followed by dilation of the urethra from F8 initially to F14 and F16. Again, the ureteroscope was used to determine the length of the strictured urethra, its distance to the external urethral orifice, and whether it was normally located. An F24 balloon catheter and then a metal urethral calibrator was used for the dilation of the strictured urethra. After removal of the F18-F22 urethral catheter at 8 weeks, the urinary flow rate was measured immediately and again at 3 months.

RESULTSAll the operations were successfully performed without serious complications. The maximum urinary flow rate was (13.3-29.9) ml/s (mean [17.7 ± 3.2] ml/s) at the removal of the catheter and (15.2-30.8) ml/s (mean [19.8 ± 3.9] ml/s) at 3 months after it. Smooth urination was found in all the patients during the 6-24 months follow-up.

CONCLUSIONThe application of the ureteral dilation catheter combined with, the balloon catheter under the ureteroscope is a good option for the treatment of male urethral stricture for its advantages of uncomplicatedness, safety, effectiveness, few complications, less pain, high success rate, and repeatable operation.
