Objective · To investigate the smoking hypertensive elderly, find out the status of smoking in this population, and explore effective system intervention. Methods · The smoking hypertensive elderly in Waigang Town of Shanghai who received free antihypertensive drugs were recruited to investigate and descriptively analyze the smoking status of them with questionnaires. Results · There were 77.6% of the smoking hypertensive elderly who began to smoke in the age of 13 to 25, and nearly 70% smoking for more than 40 years. There were 59.5% of these people smoking 11 to 29 cigarettes daily in recent 3 years, and 41.6% spending 200-299 yuan on smoking monthly. Conclusion · Currently almost 70% of the smoking hypertensive elderly, who receives free antihypertensive drugs, have been smoking for more than 40 years, and the average number of cigarettes smoked daily is big. It is clear that the health education attached to the policy of providing free antihypertensive drugs has not changed the behavior. Therefore, medical personnel still needs to contact the illness and smoking hazards to help the elderly reduce smoking. Besides, it proves that tobacco control should be implemented in the young population to control epidemic at the early stage.

Objective · To investigate the prevalence of passive smoking among pregnant women in Shanghai and to analyze its influencing factors and to provide the basis and suggestion for making related intervention measures to reduce the harm of secondhand smoke on the health of pregnant women. Methods · From July to October 2014, pregnant women and their spouses were recruited for a questionnaire investigation at the antenatal care clinics of 3 maternity hospitals and 3 community hospitals in Shanghai. The questionnaire included demographic information, family basic situation and cognitive status of passive smoking. Results · The passive smoking rate before pregnancy in the 2831 pregnant women, who were involved in the investigation, was 17.1%. The passive rate during pregnancy was 7.8%. The difference between these two rates was statistically significant (P<0.05). 71.0% of the pregnant women have passive smoking for 15~59 min each day. Relative to home and work place, the passive smoking rate of pregnant women in public place was the highest (P<0.05). The passive smoking rate of pregnant women was significantly associated with the educational level of smoking spouses and the attitude of pregnant women when they faced the smokers. Conclusion · The passive smoking rate of pregnant women is influenced by the educational level of their spouses and the pregnant women's feedback to the smokers face to face. Public places are the most important exposure places to secondhand smoke for pregnant women. In order to reduce the harm from passive smoking to pregnant women and their fetuses, the related measures of smoking control at home education and smoking ban in public place should be made.

OBJECTIVETo study modified ilioinguinal approach through the retrospective analysis on the surgical treatment of 63 patients with pelvic and acetabular fractures through anterior approach.

METHODSFrom January 2006 to January 2013, 63 patients with pelvic and acetabular fractures were treated with the ilioinguinal anterior approach, including 45 males and 18 females, ranging in age from 12 to 68 years old, with an average of (37.71 +/- 13.41) years old. All the patients were divided into two groups: standard ilioinguinal anterior approach group (group A) and modified ilioinguinal anterior approach group(group B). In group A, there were 26 males and 11 females, with an average age of (38.49 +/- 13.64) years old. In group B, there were 19 males and 7 females, with an average age of (36.62 +/- 13.29) years old. Intraoperative and postoperative indicators in group A and B were observed and compared, including operation incision exposure time (from skin incision to complete the ilioinguinal in front of three "windows"), the blood loss, incision close time and treatment effect of Majeed function score.

RESULTSCompared to group A, the incision exposure time of patients in group B was shorter, the blood loss (bleeding during exposure process) was less, and the close incision time was shorter, but the treatment effect of Majeed function score had no significant differences between two groups. All the patients were followed up, and the during ranged from 3 to 36 months, with an average of (18.6 +/- 9.2) months. According to Matta standard assessment reduction of pelvic and acetabular fracture, there were 28 patients got an excellent result, 8 good, and 1 fair in the group A; and 20 patients got an excellent result, 5 good, and 1 fair in the group B. According to Majeed function score for hip function, 20 patients got a satisfactory result, 12 good,4 fair and 1 poor in group A, and the mean score was 82.51 +/- 9.72; and 13 patients got an satisfactory result, 10 good, 3 fair and 0 poor in group B, and the mean score was 80.54 +/- 10.79.

CONCLUSIONThe modified approach has several advantages as follows: providing a good surgical exposure; preventing from the injury of femoral nerve, femoral artery and vein under the inguinal ligament; not needing to open the inguinal canal, which can avoid the occurrence of inguinal hernia, reduce operation prodedures and shorten operation time.

OBJECTIVETo compare the image quality of T grain green sensitive film (TML-1) and Lanex Gd(2)O(2)S rare earth intensifying screen with that of XK-1 blue sensitive film and calcium tungstate (CaWO(4)) intensifying screen, and to study the application of T grain technic to the diagnosis of lung diseases.

METHODS160 coal miners were randomly selected to take both TML-1 and XK-1 chest film of high kV radiographs at the same time. Silver halide granule, fluorescence of intensifying screen, radiographic parameters, the density at different points in the lung and chest radiographs were observed.

RESULTSSilver grains in TML-1 film were more homogeneous in distribution than in XK-1 film. Luminous intensity of Lanex Gd(2)O(2)S rare earth intensifying screen was brighter than CaWO(4) intensifying screen in the same exposure. The exposure doses of TML-1 film was reduced to one third of XK-1 film. The density of chest radiographs was 0.24 to 2.74 in TML-1 film, and 0.30 to 2.60 in XK-1 film. There were greater exposure latitude and more informations in TML-1 film. By apertured-disc observation, the fine structure of lung in TML-1 film was clearer than in XK-1 film, the shape was more concrete and reliable, visualizability was stronger.

CONCLUSIONT grain technique may obviously improve the clearness and resolution of image, and enhance the transmission of information, as well as increase the diagnostic informations.

Objective To confirm the distribution of high arsenic drinking water and the situation of endemic arsenism in Hubei Province, to provide reference basis for prevention and control of endemic arsenic disease. Methods Using typical investigation and sample investigation in 2006 and 2007, the arsenic content of water was detected sampled from 19 counties(cities or communities). And those water samples which were close to or exceeded the stipulated standard were rechecked by the national standard method. Furthermore, the situation of endemic arsenism was investigated in the cities having high arsenic contents of water. Results In 2006,10 028 water samples of 446 villages in 6 counties (cities or communities) were tested, the wells of high arsenic (> 0.05 mg/L) were found in 5 counties (cities or communities) and the proportion of the well that exceeded stipulated standard was 5.29%(530/10 028); In 2007,19 086 water samples of 1282 villages in 17 counties(cities or communities) were tested, the wells of high arsenic were found in 11 counties(cities or communities), and the proportion of the well that exceeded stipulated standard was 1.74%(333/19 086). In these two years, 29 114 water samples were tested, in which 863 water samples were exceeding the stipulated standard. The 2.96% of total wells exceeded stipulated standard and mainly distributed in 179 villages of 12 counties(cities or communities). And the highest arsenic content of water sample was 2.012 mg/L. In the endemic arsenism area, 2 critical, 1 moderate and 1 mild arsenism patients had been found. Conclusions The water of high arsenic content are scattered in Hubei Province and the situation of endemic arsenism disease is mild. Improving water aiming at decreasing arsenic and establishing patient files should be carried out immediately.

AIMTo study the effects of sodium salicylate on the expression of GABAalpha NR1 and hearing response properties of inferior colliculus neurons in mice.

METHODSThirty-six kunming mice were divided into three groups (A, B, C,). The expression of GABAalpha NR1 were measured by using RT-PCR. The intensity-rates functions, intensity-latency functions and frequency-turning curves were recorded by extracellular electrophysiological recording techniques.

RESULTS(1) The expression of GABAalpha mRNA of B group was decreased remarkably than the control group (A group, P < 0.05), there weren't noticeable differences between A group and C group (P > 0.05). The expression of NR1 mRNA of B group was increased remarkably than the control group (A group, P < 0.01), there were noticeable differences between A group and C group P < 0.05). (2) The intensity-rates functions, intensity-latency functions were monotonic while the frequency-turning curves were more broad when sodium salicylate was given. (3) The intensity-rates functions, intensity-latency functions were non-monotonic while the frequency-turning curves were sharpened after lidocaine was given.

CONCLUSIONS(1) The results suggested that administration of sodium salicylate decreased the expression of GABAalpha while increased the expression of NR1mRNA. (2) The intensity-rates functions, intensity-latency functions were monotonic, the frequency-turning curves were more broad when salicylate was given and the changes above could be reversed by given lidocaine.

OBJECTIVETo compare the outcomes of the three microsurgical strategies, inguinal high ligation (IHL), retroperitoneal high ligation (RHL) and low ligation (LL) of internal spermatic veins, in the treatment of varicocele.

METHODSWe retrospectively analyzed 120 cases of varicocele, which were equally divided into groups I , II and III to be treated by IHL, RHL and LL of internal spermatic veins, respectively. We compared the operation times, post-operative complications, recurrence rates and results of pre- and post-operation semen analysis among the three groups.

RESULTSThe mean operation time was significantly longer in group III ( [55 +/- 6 ] min) than in I ([35 +/- 10] min) and II ([42 +/- 12] min) (P<0.05), while the rate of post-operative complications remarkably higher in group I (4 cases of hydrocele [10% ] and 3 cases of epididymitis [7.5%]) than in II (2 cases of hydrocele [5%] and 2 cases of epididymitis [5%]) and III (1 case of hydrocele [2.5%] and 1 case of epididymitis [2.5%]) (P<0.05). Six to 12 (mean 9) months of follow-up visit found 2 cases (5% ) of recurrence in group I, 1 case (2.5%) in group II and none in group III, with no statistically significant difference among the three groups (P>0.05). At 12 months after surgery, group III showed significantly higher sperm concentration, grade a +b sperm and the sperm motility than the other two (P<0.05), but no significant differences were observed in these parameters among the three groups preoperatively.

CONCLUSIONAs a microsurgical approach to the treatment of varicocele, LL is better than IHL and RHL of internal spermatic veins in improving the seminal parameters of the patients.

AIMTo investigate the action of anions and anion channel blockers in the regulation of vascular contraction induced by norepinephrine (NE).

METHODSNE-induced contraction was observed in rat aorta by using routine blood vascular perfusion in vitro.

RESULTSThe anion channel blockers niflumic acid (NFA) and 5-nitro-2-(3-phenoxylpropylamino)-benzoic acid (NPPB) produced inhibitory effects on NE-evoked contractions in the aorta. NE-induced contraction was not significantly changed after the extracellular Na+ was replaced by choline, in contrast, the vascular was relaxed when the extracellular Cl- was replaced by glutamate. Moreover, the vasoconstriction induced by NE was further enhanced with the replacement of the extracellular Cl- by Br-, which was still sensitive to either NFA or NPPB.

CONCLUSIONSAnion channels play an important role in the regulation of blood vascular tone, which may be responsible for the salt-sensitivity hypertension.
