Objective To evaluate the effectiveness of tobacco control interventions among employees in centers for disease control and prevention (CDC) in Hebei Province. Methods Tobacoo control interventions, including health education, Quit and Win competition, and founding smokeless CDC, were carried out in CDC system in Hebei Province from May 2006 to June 2008. Surveys on smoking rate of employees and on average cigarette quantity consumed by male employee smokers were conducted at the beginning and the end of the interventions. Results In 2006, 9 931 employees in 174 centers at provincial, city, county level in Hebei Province participated in this study. The overall smoking rate was 25.69%. Male employees had a higher smoking rate (51.28%) than the females (0.68%). The smoking rate of male employees was 50.92%, 49.48% and 51.72% for provincial, city and county CDC levels, respectively. The average cigarettes consumed by one smoker in one day were 15.0. In 2008, 9 139 employees in 189 centers participated in this study. The overall current smoking rate was 25.07%. The smoking rate was 52.26% and 0.43% for males and females, respectively. The smoking rates of male employees in provincial and city CDCs were 43.93% and 46.18%, significantly lower than those in 2006. The smoking rate of male employees in county CDCs was 53.98%, much higher than that in 2006. The average cigarettes consumed by one smoker in one day in 2008 were 12.4, significantly less than that in 2006. The current smoking rate of male employees in smokeless CDCs was 48.0% , significantly lower than 56.9% in non smokeless CDCs. Conclusion Male employees in Hebei Province CDC system had a high smoking rate. Tobacco control interventions play a role in reducing smoking rate and cigarettes consumption.

Objective To explore the images and diagnostic evaluation of X-ray combined with ultrasound in paralytic intestinal obstruction caused by antipsychotic agents. Methods The data of X-ray and ultrasound of 124 cases of clinically diagnosed paralytic intestinal obstruction caused by antipsychotic agents were analyzed retrospectively, as well as their rates of confirmed diagnosis. All the 124 patients were examined by erect abdominal radiography and fluoroscopy,68 of the 124 patients by ultrasound. Results According to their typical images,the rate of X-ray confirmed diagnosis was 87.9%(109/124) with 15 missed diagnosis and the rate of missed diagnosis was 12.1%( 15/124);the rate of ultrasound confirmed diagnosis was 82.4%(56/68) with 12 missed diagnosis and the rate of missed diagnosis was 17.6%(12/68). There was no significant difference between X-ray and ultrasound (P＞ 0.05 ). Compared with X-ray or ultrasound ,X-ray combined with ultrasound in the diagnosis of paralytic intestinal obstruction could increase the rate of confirmed diagnosis (100.0% ,68/68),and decrease the rate of missed diagnosis (0),the difference was statistically significant (P＜ 0.05 ). Conclusions X-ray examination is the first choice to diagnose paralytic intestinal obstruction caused by antipsychotic agents,but ultrasound has the advantage of finding fluid in abdominal cavity. To reduce missed diagnosis, X-ray should be combined with ultrasound.

Objective To discuss the feasibility of neuroendoscopic third ventriculostomy for chronic posttraumatic hydrocephalus (PTH).Methods Nineteen cases of chronic PTH treated with neuroendoscopic third ventriculostomy between October 2010 and October 2014 were analyzed retrospectively.There were 13 males and 6 females, aged 11-57 years (mean, 36.3 years).Trauma resulted from traffic accidents in 14 cases, falls in 4 cases and blunt object hitting in 1 case.Of the 19 cases analyzed, 5 had Glasgow Coma Scale (GCS) score of 13-15, 5 had score of 9-12 and 9 had score of 5-8 at admission.Results of operation were assessed with the Canada multicenter evaluation criteria.Prognosis was analyzed with the Glasgow Outcome Scale (GOS).Results All cases were followed up for mean 13.6 months (range, 6-26 months).Improvement of symptoms was achieved in 17 cases, but was not seen in 2 cases.Of the 2 cases, one required ventriculoperitoneal shunt two weeks after ineffective ventriculostomy, and one required second ventriculostomy one month after the presence of stoma blockage.No serious complications occurred.At follow-up, 9 cases had GOS score of 5, 8 cases had score of 4 and 2 cases had score of 3.Conclusions Neuroendoscopic third ventriculostomy is in line with the physical characteristics in cerebrospinal fluid circulation, which implies no shunt implantation, less operative trauma and less complications.The procedure is an effective approach for chronic PTH.

Objective To evaluate the effect of curcumin on cognitive dysfunction in a rat model of trigeminal neuralgia.Methods Thirty healthy adult male Sprague-Dawley rats,weighing 200-250 g,were randomly divided into 3 groups (n=10 each) using a random number table:sham operation group (Sham group),trigeminal neuralgia group (TN group),and trigeminal neuralgia + curcumin group (TN + Cur group).Trigeminal neuralgia was produced by injecting cobra venom solution 4 μl into the sheath of the infraorbital nerve in TN and TN + Cur groups.Starting from 15 days after establishment of the model,1.5 ml peanut oil was injected through a gastric tube into stomach twice a day (in the morning and at night) for 28 consecutive days in TN group,and curcumin 45 mg/kg (dissolved in 1.5 ml peanut oil) was injected through a gastric tube into stomach twice a day (in the morning and at night) for 28 consecutive days in TN + Cur group.The cognitive function was assessed using Morris water maze test after the end of treatment.The escape latency,swimming speed,ratio of time of staying at the target quadrant,and the number of times the animals crossing the platform were recorded.The pathological changes in the hippocampal CA1 region were observed with an electron microscope.The ultrastructure of neurons,organelles and synapses in the hippocampal CA1 region was examined with a transmission electron microscope.Results There was no significant difference in the swimming speed between the three groups (P＞0.05).Compared with Sham group,the escape latency on 1st-4th days was significantly prolonged,the ratio of time of staying at the target quadrant was decreased,and the number of times the animals crossing the platform was decreased in TN group,and the escape latency was significantly prolonged on 3rd and 4th days in TN + Cur group (P＜0.01).Compared with TN group,the escape latency on 2nd-4th days was significantly shortened,the ratio of time of staying at the target quadrant was increased,the number of times the animals crossing the platform was increased (P＜0.01),and the pathological changes of hippocampal tissues were attenuated in TN + Cur group.Conclusion Curcumin can improve cognitive dysfunction in a rat model of trigeminal neuralgia.

OBJECTIVE To investigate the antitumor effect and toxicity of doxorubicin-heparinized mesoporous silicon nanoparticles drug carrier system (DOX-HMSN) on H22 hepatoma mice. METHODS An experimental animal model of H22 hepatoma mice was established. Fifty male Kunming mice were divided into five groups:model control group,HMSN 8 mg?kg-1 group,DOX-HMSN 4,8 mg?kg-1 groups, and DOX 2 mg?kg-1(once every other day)group. Continuous intravenous injection was given once a day for 14 d. Tumor was completely stripped and weighed,and tumor inhibitory rate was determined. Pathological change of tumor tissue was observed by HE staining in H22 mice. White blood cell count was performed and the thymus index and spleen index were calculated. Levels of serum creatinine (Scr),blood urea nitrogen(BUN),glutamic pyruvic transaminase(GPT)and glutamic-oxalacetic transaminase(GOT)in serum were determined. BCL-2,BAX and vascular endothelial growth factor (VEGF)expression of tumor tissue were analyzed using Western blot. RESULTS The inhibitory rate of tumor was 20.5%,40.4%,54.8%,and 67.5%,respectively,in HMSN 8 mg?kg-1 group,DOX-HMSN 4, 8 mg?kg-1 group and DOX 2 mg?kg-1 group(P<0.01). HE results showed that HMSN 8 mg?kg-1,DOX-HMSN 4,8 mg?kg-1and DOX 2 mg?kg-1 induced tumor necrosis and nuclear dissolution of the tumor cells in H22 mice. The white blood cell count,thymus index and spleen index of mice were not signifi?cantly different between control group and HMSN group or DOX-HMSN 4 and 8 mg?kg-1 group. The levels of Scr and BUN of mice did not change obviously in HMSN 8 mg?kg-1or DOX-HMSN 4,8 mg?kg-1 groups. Compared with the model control group,the level of GPT and GOT of mice increased in the DOX 2 mg?kg-1group but decreased in HMSN 8 mg?kg-1 and DOX-HMSN 4 and 8 mg?kg-1 group(P<0.05). Compared with the control,the BAX/BCL-2 ratio(from 0.49 ± 0.06 to 0.79 ± 0.08,1.23 ± 0.14 and 1.04±0.14)increased but the VEGF expression of tumor(from 1.39±0.14 to 1.13±0.12,0.75±0.08 and 0.94 ± 0.09)decreased significantly in DOX-HMSN 4,8 mg?kg-1 and DOX 2 mg?kg-1 group(P<0.05). CONCLUSION DOX-HMSN can inhibit the tumor growth of H22 tumor-bearing mice and its antitumor mechanism might be related to inducing tumor cell necrosis and apoptosis and inhibiting tumor angiogenesis.
