OBJECTIVETo investigate the incidence and risk factors for hypertension among taxi drivers working different shifts.

METHODSUsing the cluster sampling method, 415 day-shift and 304 night-shift taxi drivers in Jinan, China were selected and investigated. The influencing factors for hypertension were analyzed.

RESULTSThe incidence of hypertension in all taxi drivers was 33.2%. The incidence of hypertension in night-shift drivers was significantly higher than that in day-shift drivers (37.8% vs 29.9%, P<0.05). According to multivariate analysis, the incidence of hypertension in day-shift drivers was closely related to body mass index (BMI), working years, working hours, sleep duration, rest days, diet quality, water intake, and smoking, while the incidence of hypertension in night-shift drivers was closely related to BMI, working years, working hours, part-time job, sleep duration, rest days, and drinking.

CONCLUSIONBMI, working years, and working hours are the common risk factors for hypertension in day-shift and night-shift drivers. Sleep duration and rest days are the common protective factors. The risk factors for hypertension in taxi drivers vary with different shifts.

Objective To observe the effects of fennel essential oil and water extracts (distilled oil is not included) on gastrointestinal motility disorder caused by atropine in mice.Methods Kunming mice were randomly divided into blank control group, model group atropine, water extracts group, fennel essential oil group, mosapride group. Blank control group and model group atropine were orally administered with normal saline of 0.2 ml/10 g. Water extracts group was orally administered with Water extracts (75 mg/ml) of 0.2 ml/10 g. Fennel essential oil group was orally administered with Essential oil of 300 mg/kg. Mosapride group was orally administered with mosapride(15 mg/ml). Subjects were orally treated for 3 d. After fasting for 18 h, blank control group was intraperitoneally injected saline on the fourth day, and other groups were injected atropine sulfate injection to induce animal model of gastrointestinal motility disorder. Blue dextran(BD)2000 was used to observe the gastric emptying rate and rate of intestinal propulsion. Results Gastric emptying rates of fennel essential oil group, mosapride group, water extracts group and model group atropine were respectively(91.97±4.42)%, (90.26±5.81)%, (80.01±6.27)%,(72.88±9.13)%,and intestinal pushing rates were respectively(53.32±7.49)%,(53.02±9.13)%,(44.16±7.68)%,(37.52±6.19)%.Fennel essential oil, mosapride and water extracts enhanced the gastric emptying and intestinal propulsion in gastrointestinal motility disorder animal caused by atropine(P values were 0.004、0.001、0.004、0.003、0.025、0.015),where Fennel essential oil and mosapride were superior to the water,extracts(P values were 0.000、0.002、0.001、0.001).Conclusion Fennel extracts may promote gastrointestinal movement of atropine-induced gastrointestinal motility disorder in mice and fennel essential oil is the main active ingredient.

Objective To evaluate the significance of color Doppler ultrasound examination of renal blood flow combined with the detection of bone morphogenetic protein-7(BMP-7)in early diagnosis of type 2 diabetic nephropathy.Methods Blood BMP-7 level was tested in 90 patients with type 2 diabetic nephropathy and 30 controls,and parameters of renal blood flow were measured by color Doppler ultrasound examination.Blood BMP-7 level as well as resistant index(RI)of segmental renal artery(SRA)and interlobar renal artery(IRA),were compared between these two groups.Results Compared with controls,blood BMP-7 level gradually decreased with the aggravation of diabetic kidney damage(P＜0.01).The peak systolic velocity(Vmax)and the end diastolic velocity(Vmin)of SRA and TRA were slowed gradually,while RI increased(P＜0.01).Blood BMP-7 level was negatively correlated with IRA's and SRA's RI of IRA and SRA(r =-0.603,P＜0.01;r =-0.652,P＜0.01).Conclusions Color Doppler ultrasound examination of renal blood flow combined with detection of BMP-7 might play an important role in early diagnosis of type 2 diabetic nephropathy.

To investigate the neuroprotective effect and possible mechanism of masitinib on cerebral ischemia-reperfusion injury in rats, healthy adult male Sprague-Dawley rats were divided into sham group (n = 12), model group (n = 12), masitinib low dosage group (n = 12), masitinib middle dosage group (n = 12), and masitinib high dosage group (n = 12). All rats was subjected to middle cerebral artery occlusion (MCAO) for two hours and reperfusion except sham group, and received treatment twice per day for 7 days once reperfusion started.Neurological score, infarct volume, and brain water content were detected; some autophagic markers, apoptotic and inflammatory cytokines were evaluated by Western blot and PCR after 7 d of reperfusion. Treatment with masitinib significantly ameliorated neurologic deficit, infarct volume and brain water after I/R injury. Masitinib also decreased the ratio of LC3II/I and the expression of Beclin-1 and increased the expression of p62 in the brain tissues of rats with I/R injury.Furthermore, it could inhibit apoptosis-related proteins and NF-κB expression. Masitinib could relieve the cerebral ischemia-reperfusion injury in rats through inhibiting autophagy and apoptosis.

Objective:To systematically evaluate the diagnostic value of fine-needle aspiration washout fluid for measuring thyroglobulin (FNA-Tg) and fine-needle aspiration cytology (FNAC) in cervical lymph node metastasis of papillary thyroid carcinoma.Methods:Chinese Journal Full-Text Database, Wanfang Database, VIP Chinese Science and Technology Journal Database and other databases from January 2016 to December 2020 were retrieved. And then diagnostic trials from the databases regarding the comparison of FNA-Tg and FNAC in the diagnosis of papillary thyroid carcinoma with neck lymph node metastasis based on the histopathological diagnosis as the gold standard were included. The literatures were screened out according to the diagnostic test inclusion criteria recommended by the Cochrane Collaboration Screening and Diagnostic Test Methods Group; and then the quality of the included literatures was evaluated and feature information was extracted. Review Manager 5.0 and MetaDiSc software were used to conduct Meta analysis, and a summary receiver operating characteristic (SROC) curve of FNAC and FNA-Tg in the diagnosis of lymph node metastasis was drawn to calculate the area under the curve and to judge the diagnostic efficacy.Results:A total of 19 articles and 2 792 cervical lymph nodes were finally included. The sensitivity of FNAC and FNA-Tg in the diagnosis of cervical lymph node metastasis in papillary thyroid carcinoma was 0.80 (95% CI 0.78-0.81) and 0.92 (95% CI 0.91-0.93), respectively; the specificity was 0.93 (95% CI 0.92-0.95) and 0.91(95% CI 0.89-0.93); the diagnostic odds ratio was 51.55 (95% CI 38.61-68.81) and 110.03 (95% CI 82.18-147.32), respectively; the areas under the SROC curve was 0.900 and 0.968, respectively. Conclusions:The accuracy of FNA-Tg in the diagnosis of cervical lymph node metastasis of papillary thyroid carcinoma is higher than that of FNAC. FNA-Tg can be used as an important diagnosis supplement to FNAC and it can be widely used in clinical practice.
