Clonorchiasis is one of the food?borne parasitic diseases. Adult parasites live in the human liver and gallbladder tube system,causing serious complications,such as gallstones,cholecystitis and cholangitis,and even bile duct cancer. The disease is very popular in our country,and the population infection rate is high. It is an important public health problem. Guang?dong Province is the earliest province being found of clonorchiasis and with serious epidemic. In the second national human para?sitic diseases distribution survey,the results showed that the average infection rate of Clonorchis sinensis in the epidemic areas in Guangdong was 16.42%. It is estimated that the population of C. sinensis infection is over 6 million. The prevention and con?trol of clonorchiasis in China is still in the initial stage currently and we face many challenges such as unclear epidemic charac?teristics and transmission mode,and lack of long?term prevention and control mechanism. This article introduces the epidemic situation of clonorchiasis and prevention and control strategies and measures in Guangdong.

Objective To investigate the current situation of psychological capital and job burnout of psychiatric nurses and explore the relationship between psychological capital and job burnout.Methods There were 142 psychiatric nurses collected in the study by convenience sampling.The Psychiatric Capital Questionnaire (PCQ) and Nurse Burnout Scale (NBS) were used to measure the level of psychiatric capital and job burnout of psychiatric nurses.The Pearson correlation analysis was used to explore the relationship between psychological capital and job burnout.Results The psychological capital of psychiatric nurses had a negative correlation with job burnout; the higher of the nurses' psychological capital,the lower their sense of job burnout,vice versa.Conclusions In order to improve nursing quality,nursing managers can reduce the job burnout by improving the psychological capital of psychiatric nurses.

In recent years, the morbidity rate of pediatric asthma showed a rising trend.The typical symptom of recurrent wheezing(＞ 3 times/year) in infants is the starting point for the diagnosis of asthma in children and may be the early clinical manifestation of asthma.Chronic airway inflammation, which inducing airway hyperresponsiveness is the main pathophysiology of recurrent episodes of wheezing.Monitoring of fractional exhaled nitric oxide (FeNO) is a simple, fast, effective, and noninvasive marker of airway inflammation in asthma.The concentration of nitric oxide can effectively reflect the airway inflammation and is positively correlated with the severity of airway inflammation.Monitoring airway inflammation is helpful to diagnose and treat the asthmatic children, and for predicting asthma exacerbation, guiding and monitoring the asthma.Thus, this review will discuss FeNO measurements among wheezing infants and asthmatic that have been identified in large-scale studies recently.

In this study,changes in immunity were observed in 120 patients undergoing laparoscopiccholecystectomy. It was found that postoperative levels of IgG,IgM,CD3+,CD4+,and CD8+ were significantly higher than that of preoperative and postpneumoperitoneal with CO2 (P

Objective To observe the clinical effect of holmium laser for the treatment of ureteral calculi under ureteroscope .Methods In 205 cases of ureteral calculi with ureteroscopic holmium laser treatment ,the stone expulsion rate,complication,gravel rate were analyzed.Results Operation time was (65.3 ±18.4)min,hospitaliza-tion time was (5.6 ±2.7) d,the success rate of operation was 95.1%(195/205),incidence of complications (hemorrhage in 1 cases,perforation in 2 cases,20 patients with fever) was 11.2%,3 cases of calculi moved to pel-vis,indwelling double J tube in operation ,postoperative ESWL,after 2weeks ~3months stone completely lithagogue rate was 98.4%(192/195).7 cases converted to open operation .After operation 3 cases of ureteral calculi and 5 cases of renal pelvis stones were in postoperative ESWL ( extracorporeal shock wave lithotripsy ) , which was completely discharged and cure .Conclusion There are some advantages of ureteroscopic holmium laser lithotripsy for ureteral calculi with high success rate,the stone expulsion rate high,fewer complications,less trauma,safe and reliable.

The review summarized the diagnostic strategy of ischemic cerebrovascular diseases and introduced some progress in clinic.As ischemic cerebrovascular diseases were highly heterogeneous,the review analyzed their characteristics step by step.Through the primary diagnosis,etiological diagnosis,evaluation of risk factors and factor analysis of the whole body,the review describe the diagnostic program of the diseases and provide suggestion about the individually therapy and prevention.

AIM: To extract Zanthoxylum oil from the seeds of Zanthoxylum bungeanum Maxin, and find out a better extraction method and its optimized operating conditions. METHODS: Zanthoxylum oil was extracted by distillation method, solvent extraction and supercritical fluid extraction, respectively. The products gained in each experiment was analyzed by GC after it had been methyl esterified. RESULTS: The yield of Zanthoxylum oil extracted by distillation, solvent extraction and supercritical fluid extraction was 0.88 %, 13.73 % and 13.52 %, respectively, and its content of unsaturated fatty acid 4.50 %, 65.97 %, 74.97 %, respectively. CONCLUSION: Supercritical fluid extraction was the better of the three mehtods, whose optimized operating conditions consisted of 30 MPa pressure, 50 ?C operating temperature and 5 h extraction time.

miR-200c is a member of miR-200 family,and it plays an important role in tumor diagno-sis,metastasis and chemoresistance.miR-200c is identified as a molecular marker and prognostic indicator in cancer screening.It can inhibit epithelial-mesenchymal transition,tumor invasion and metastasis,and increase the chemosensitivity of tumor cells,but the relevant mechanism is still not fully clear.The studies of miR-200c and some factors in regulatory pathway are beneficial to promote its applications in clinical diagnosis.

BACKGROUND:Total knee arthroplasty for knee osteoarthritis accompanied with extra-articular deformity is stil chal enging. An individual replacement plan should be designed to obtain good mechanical axis and to recover suitable soft-tissue balance. OBJECTIVE:To observe the safety and feasibility of individual y designed one-stage total knee arthroplasty for knee osteoarthritis combined with ipsilateral femoral extra-articular deformity. METHODS:A total of eight patients with knee osteoarthritis combined with ipsilateral femoral extra-articular deformity were enrol ed in this study. According to preoperative plan, five patients underwent intra-articular compensatory osteotomy, and the remaining three received extra-articular corrective osteotomy. Multi-planar deformities as wel as soft-tissue conditions were recorded. Main outcome measures included the hospital for special surgery score, Western Ontario and McMaster Universities Arthritis Index score and alignments deviation. RESULTS AND CONCLUSION:The patients were averagely fol owed up for 29 months. The hospital for special surgery score changed from preoperative 32.5 points to postoperative 87.5 points. The Western Ontario and McMaster Universities Arthritis Index score was increased from preoperative 37.1 points to postoperative 88.8 points (P<0.05). Mean mechanical axis deviation (either varus or valgus) changed from preoperative 17.1° to postoperative 1.4° (P<0.05). Al cases with extra-articular corrective osteotomy healed within 3 months, and none had postoperative infection, loosening or venous thromboembolic events. One patient was with 5° residual knee anti-sheets. Results verified that one-stage total knee arthroplasty procedures are effective in the treatment of knee osteoarthritis accompanied with ipsilateral femoral extra-articular deformity in accordance with individual preoperative plan.
