Objective To explore the effect of comprehensive interventions on protective behaviors of sanitary workers against occupational exposure in hospitals. Methods Comprehensive interventions were done in 50 sanitary workers in our hospital during September 2013 to September 2014, with the intervention contents including establishment of sanitary workers management system, education training, on-the-spot inspection, signature of duty informs, planning of occupational exposure prevention flow chart. The intervention lasted 12 months. Then the score on occupational exposure prevention knowledge and behaviors, the qualification rate of all indexes and all occupational harms in pre-intervention and post-intervention were compared. Result The score on occupational exposure preventive knowledge after intervention was significantly higher than that before intervention , the qualification rate after intervention was higher than that before intervention and the incurrence of occupational harms was significantly lower than that before intervention (P < 0.01). Conclusion Multiple measures including education, supervision, inspection, duty informing and flow chats can strengthen the awareness of preventing occupational exposure and lower the incidence of occupational harms among the sanitary workers.

Objective: To evaluate the experience of surgical treatment of anastomotic recurrence following resection of esophageal carcinoma. Methods: Reoperation was performed in 11 patients with anastomotic recurrence. The surgical procedure performed included cervical esophagocolostomy in 5, cervical esophagogastrostomy in 3, esophagocolostomy and esophagogastrostomy at the top of chest in 2, respectively, and thoracotomy in 1. Results: There was one operative death with mortality rate of 9.1%. The cause of death was respiratory failure. 1-, 3-and 5-year survival rates were 77.8% (7/9), 44.4% (4/9) and 22.2% (2/9), respectively. Conclusion: Reoperation is still effective for some patients with anastomotic recurrence. Early diagnosis and prompt surgical treatment can improve the outcome.

Objective To evaluate the function of residual esophagus and stomach after subtotal esophagectomy and cervical gastroesophagostomy for esophageal carcinoma. Methods Manometry was performed in 21 patients who underwent cervical anastomosis after subtotal esophageal resection. The data was compared with normal subjects. Results The mean value of pharyngeal resting pressure was (1.20?2.03) mmHg(1mmHg=0.133kPa), and that of contraction pressure was (72.37?16.95) mmHg. The resting pressure of upper esophageal sphincter (UES) was (28.20?15.60) mmHg, and closing pressure was (107.10?28.43) mmHg. The resting pressure of residual esophagus was (15.98?11.10) mmHg, and contraction pressure was (48.45?18.37) mmHg. The resting pressure of stomach was (3.53?3.30) mmHg. Incidence of primary wave of esophagus was (57.14?34.50)%. The resting pressure of residual esophagus was much higher than that of normal group (P

ObjectiveTostudythemolecularmechanismoflanthanumonblocking lipopolysaccharide(LPS)-mediated activation of nuclear factor-kappaB (NF-κB)signaling in macrophages.MethodsThe RAW264.7 macrophages were cultured routinely and divided into 4 groups randomly:LaCl3 +LPS group,LPS group,LaCl3 group and control group.The nuclear translocation of p65 protein was detected by immunocytochemistry.Total,cytoplasmic and nuclear proteins were extracted respectively,and then the binding activity of p65 with the target gene was measured by ELISA.Western blot assays were also performed to detect the expression levels of the proteins,including nuclear p65,IκBα and IKK kinase,the phosphorylation status of IκBα and IKK kinase.ResultsLanthanum can block LPS-induced activation of p65 protein through various ways,such as inhibiting its nuclear translocation,reducing its expression in the nuclei and decreasing its binding activity with the target genes.Lanthanum inhibited the degradation of LPS-induced IκBα,but the phosphorylation of LPS-induced IKKβ can not be blocked by lanthanum,nor did the phosphorylation ability of p-IKKβ on IκBα.Conclusion Lanthanum inhibited the degradation of IκBα,nuclei translocation of p65 protein and its binding activity with the target genes,thereby inhibited LPS-induced NFκB activation,which might be one of the inhibition mechanisms of lanthanum on nuclear activation.

OBJECTIVE To investigate the effects of aerobic exercise on enteric nervous injury in rats exposed to malathion.METHODS Adult male Wistar rats were treated with non-load swi mming every other day,three ti mes a week,each one hour,for six weeks.Before exercise,the rats were trea-ted with malathion 100 mg·kg -1·d -1 by oral gavage,six days a week,for six weeks.The activities of seru m acetylcholinesterase(AChE)and butyrocholinesterase(BuChE)were determined.In addition,the s mall intestinal propulsion indexes were measured.Also,the distribution of nerve plexus in ileu m was observed.The i mmunohistoche mical method was used to measure the levels of protein gene-related petide 9.5 (PGP9.5),substance P (SP),and vasoactive intestinal peptide (VIP).RESULTS Co m-pared with normal control,malathion exposure decreased the activities of seru m AChE and BuChE (P<0.01 ),increased the s mall intestinal propulsion indexes (P <0.05).In addition,the levels of PGP9.5 decreased (P<0.05).At the sa me ti me,the levels of SP increased,and the levels of VIP decreased (P<0.05).Aerobic exercise did not change the activites of cholinesterases,but decreased s mall intes-tinal propulsion indexes,increased the levels of PGP9.5,decreased the levels of SP,and increased the levels of VIP.Co mpared with the malathion exposure only,the rats in malathion ad ministration co mbined with aerobic exercise group de monstrated much lower activites of cholinesterase (P <0.01 ),and the s mall intestinal propulsion indexes decreased fro m (89 ±4)% to (79 ±5)%(P <0.01 ).Moreover,the levels of PGP9.5 increased fro m 0.012 ±0.003 to 0.029 ±0.015 (P <0.01 ).At the sa me ti me,the levels of SP decreased fro m0.174 ±0.067 to 0.1 10 ±0.057(P<0.05),and the levels of VIP increased fro m 0.0076 ±0.0029 to 0.01 1 1 ±0.0047 (P <0.05).The levels of above para meters were sa me or close to those of the normal control.CONCLUSION Malathion exposure induced disorders of enteric nervous syste m in rats,and the aerobic exercise abated the toxic response in enteric nervous syste m of malathion exposure rats.However,these effects were not mediated through recovery of cholinesterases inhibition.

Objective:To explore the effect of handicraft training administered over the Internet on sensation disorders and on the mental status and life quality of stroke survivors.Methods:A total of 75 stroke survivors in the sequelae stage and with sensory disturbance were randomly divided into a general training group of 26 (group A), a handicraft training group of 26 (group B), and a handicraft training group of 23 using Internet instruction (group C). In addition to 40 minutes of routine physical and sensory training rehabilitation every morning, groups A and B were given traditional training and handicraft training, while group C was given handicraft training delivered over the Internet for 40 minutes every afternoon, five days a week for 4 weeks. The traditional training involved inserting wooden boards, plate grinding, as well as sorting beans. The handicraft training involved digital painting, making non-woven flowers, silk screening flowers and paper-rolling. Before and after the 4 weeks of treatment, all of the subjects were assessed using the Fugl-Meyer sensory assessment (FMA-S), the Hamilton Anxiety Scale (HAMA), the Modified Barthel Index (MBI), and the physical component summary scale (PCS) and mental component summary scale (MCS) of the 36-item short-form health survey.Results:After the treatment, significant improvement was observed in their average scores of all three groups in all of the assessments. Groups B and C showed significantly greater improvement in the average FMA-S, HAMA and MBI scores than group A. And the average HAMA and MCS scores of group C were significantly better than those of group B.Conclusion:Handicraft training delivered over the Internet can improve the sensory functioning, mental status and life quality of stroke survivors in the sequelae stage with sensory disturbance.
