Objective To understand the health of the electronic waste (e-waste) treatment workers and the adverse effects of e-waste on the workers engaged in e-waste dismantlement.Methods Health states were assessed by questionnaire investigation on 226 e-waste dismantlement workers and 172 non e-waste dismantlement workers (control group).Results The prevalence rates of headache/vertigo(47.7%),tetter /itch (15.0%),nausea(11.1%),insomnia(9.7%),hypomnesia (5.3%),nasal obstruction(5.3%),and conjunctiva congestion(4.8%) in e-waste dismantlement workers were significantly higher than that in the control group,and it seemed that the severity of the symptoms was strongly related to the type of work.Furthermore,there was a tendency that rate of insomnia raised with the length of service in the circuit boards dismantlement group.Conclusion E-waste dismantlement will produce adverse effects on health of the employed workers.

ObjectiveTo investigate the relationship between surgical manipulation and hematogenous spreading micrometastasis in patients with colorectal carcinoma.MethodsNested RT-PCR was used to detect the expression of cytokeratin 20 (CK20) mRNA in the peripheral blood of 37 colorectal cancer patients without distal metastasis (experimental group) undergoing radical resection which were subdivided into group A (tumor drainage veins were first ligated) and group B (without precedent ligation of the veins).Results CK20 mRNA was positive by nested RT-PCR in the peripheral blood in 9 out of 10 colorectal cancer patients with known distant metastasis,while it was negative in all 10 volunteers and all 10 patients with benign colorectal lesions. CK20 mRNA was detected in 14 of 37 (37 8%) cases in the peripheral blood sampled preoperatively, while the positive ratio rose to 59 5% (22/37) during surgical procedures (? 2=4 900, P0 05). ConclusionCK20 mRNA by nested RT-PCR was highly sensitive and specific for the determination of circulating micrometastasis in colorectal cancer patients. Surgical manipulation significantly increased the incidence of hematogenous spreading micrometastasis, which can′t be prevented by precedent ligation of the refluent veins of the tumor during operation.

The electrocardiography (ECG) telemonitoring system is briefly introduced, especially the development progress, including the wearable technology. For early cardiac rehabilitation (CR) after acute myocardial infarction (AMI), the ECG telemonitoring system can monitor heart rate, blood pressure, heart rate recovery (HRR), which is confirmed to assess autonomic nervous function;as well as rate pres-sure product (RPP), which is confirmed to speculate lactate anaerobic threshold during CR, can be calculated to guide the exercise intensity of CR progress. Finally, the legal liability issues if accidents occurred in home-based CR program, and the innovation, such as combining with the network, are discussed.

PurposeTo investigate the relationship between the serum oxidized low-density lipoprotein (ox-LDL) level and carotid vulnerable plaque in patients with acute cerebral ischemic stroke, and to evaluate the ability of serum ox-LDL in identifying vulnerable carotid plaques.Materials and Methods 181 patients with history of acute cerebral ischemic stroke were recruited. According to the results of carotid ultrasound patients were divided into non plaque group (n=48), stable plaque group (n=38) and vulnerable plaque group (n=95). The serum total cholesterol, triglyceride, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol, fasting plasma glucose and ox-LDL were measured. Carotid intima-medial thickness (CIMT), total carotid plaque area (TPA) and the characters of plaque were examined with color Doppler ultrasound.Results The serum ox-LDL and the number of patients with hypertension in plaque group were significantly higher than that in the non-plaque group (P<0.05). The serum ox-LDL and TPA in the vulnerable plaque group were significantly higher than that in the stable plaque group (P<0.05). Serum ox-LDL in patients with acute cerebral infarction was positively correlated with CIMT, serum total cholesterol and LDL-C (r1=0.154,P<0.05;r2=0.338, P<0.05;r3=0.385,P<0.05). Logistic regression analysis showed that serum ox-LDL was an independent risk factor for carotid vulnerable plaque (OR=1.038, 95%CI 1.008-1.069, P<0.01).Conclusion The serum ox-LDL is independently associated with the formation of vulnerable plaque in patients with acute cerebral infarction. This study suggests that ox-LDL can be used as a biomarker in screening for vulnerable carotid plaque in clinical practice. Carotid ultrasound combined with serology can early identify carotid artery vulnerable plaque that may lead to cerebral ischemic events.

Objective To study the X-ray findings of post-traumatic osteolysis and to improve the knowledge of that disease.Methods X-ray features of 7 cases of post-traumatic osteolysis confirmed by clinical findings and pathology were reviewed retrospectively.There were 5 females and 2 males.from 9-56 years(mean 34 years)of age.Three patients had traffic accidents and 4 had trauma unrelated to traffic accidents.Osteolysis occurred from 3 to 18 months after trauma(1 case at 18 months,2 cases at 10 months,2 cases at 6 months and 2 cases at 3 months).Results There were 2 pubis fractures,1 distal tibiofibular shaft fracture,1 femoral neck fracture,1 humeral upper end commiuuted fracture,1 shoulder joint dislocation.and 1 soft tissue swelling around the wrist.The X-ray findings are:3 massive osteolysis,3 plaque flake osteolysis and 1 cystic osteolysis.There were no hardening of bony edge at the site of osteolysis in all 7 cases,clear margin in 5 cases and ill-defined margin in 2 cases,no residual bone in osteolytic area in 4 cases and residual bone in octeolytic area in 3 cases,no periosteal reaction and thickerning of bony cortex in osteolytic area in all 7 Cascs,bone repair in 2 cases and no bone repair in 5 cases.Histopathological findings showed:extensive capillary hyperplasia and fibrous tissue hyperplasia;hyperemia and swelling of synvium,proliferation of granulation tissue,osteonecrosis,increased osteoclast activity,some inflammatory cells,no evidence of neoplastic cells in the involved area.Conclusions Posttraumatic osteolysis is closely related to trauma.X-ray findings include massive osteolysis,plaque-like osteolysis,and irregular cystic changes.Early dignosis may be a challenging task.

Objective To study the clinical value of DSA diagnosis and interventional therapy for non-neoplastic lower digestive tract hemorrhage. Methods Non-neoplastic lower digestive tract hemorrhage were diagnosed in 21 patients. Eight cases underwent embolization with gelfoam and 13 cases with infusion of pitressin. Results Intestinal angiodysplasia was found in 14 cases, colonic diverticulum in 2 and hemorrhage of unknown cause in 5. Hemorrhage in all patients was stopped after the interventional therapy with no serious complications. During the follow-up of 25～74 months, intestinal angiodysplasia bleeding recurred in 4 patients. Conclusions DSA is very helpful in the diagnosis of non-neoplastic lower digestive tract hemorrhage and interventional therapy is safe and effective for the stoppage of the bleeding.

ObjectiveTo investigate the effect of speech therapy on mental health of patients with aphasia. MethodsCRRCAE and SCL-90 were used to assess the speech and mental state in 28 aphasia patients. All aphasia patients were treated by using speech therapy and the changes before and after treatment were compared. ResultsThe scores in listening comprehension, repetition, naming, reading,reading comprehension, writing and counting were distinctly higher at post-treatment than that at pre-treatment. All SCL-90 factor's levels at post-treatment were distinctly reduced than that at preat post-treatment(P<0.01).Conclusions Speech therapy can improve the language function,as well as mitigate the mental symptoms.

Background and purpose:Currently, subjective questionaire is the most frequently used methods to evaluate swallowing dysfunctions after radiotherapy in nasopharyngeal carcinoma patients, while lacking of effective objective examinations. This study aimed to explore effective methods to evaluate swallowing dysfunctions after radiotherapy in nasopharyngeal carcinoma patients, and gain knowledge of the incidence and severity of swallowing dysfunctions. Methods: From Oct. 2013 to Dec. 2013, 128 consecutive outpatients with previously treated nasopharyngeal carcinoma received esophageal barium lfuoroscopy examination at there regularly follow-ups to evaluate swallowing function. Among these patients, 89 were primary treated with intensity modulated radiation therapy (IMRT) and 39 with conventional radiotherapy (CRT). In this study, each patient received esophageal barium lfuoroscopy examination for 3 times with thin, thick and pasty barium and were dynamically observed using X-ray fluoroscopy from front and lateral direction. Swallowing dysfunctions were defined as follows:①The bolus could not be swallowed and blocked in the mouth;②The dilute barium diverted to the glottis or trachea;③Residual barium delayed in the pyriform sinus and vallecula;④The movement of the hyoid bone or epiglottis were restricted;⑤Bolus prolong through the pharynx;⑥Barium slowed down when went though the esophageal entrance. Results:Of the 128 patients, incidence of dysphagia was 60.2%for the entire cohort, 52.8%for IMRT group and 76.9%for CRT group. Incidence of dysphagia for IMRT group was signiifcantly lower than CRT group (P=0.018). Dysphagia incidence within 1 year, 1 to 2 years and more than 2 years after RT were 63.1%, 33.3%and 69.0%, respectively (P=0.019). Conclusion:There was a high incidence of swallowing dysfunction for the nasopharyngeal carcinoma patients treated with radiotherapy and dysphagia incidence decreased when treated with IMRT. Esophageal barium lfuoroscopy examination is objective method to evaluate the incidence and severity of the swallowing dysfunction.
