AIM:To compared the differential sensitivity of nicotinic acetycholine receptors (nAChRs) consisting of α and β subunits with different ratios.METHODS:The cRNA of α and β subunits was obtained by in vitro transcription.The α3β2 and α3β4 nAChR subtypes were expressed in Xenopus laevis oocytes by microinjection of cRNA coding α and β subunits at α∶β ratios of 1∶10, 1∶1 and 10∶1.The pharmacological activities of nAChRs to agonist acetycholine (ACh) and antagonist α-conotoxin (CTx) RegⅡA were investigated by two-electrode voltage-clamp techniques.RESULTS:For α3β2 nAChR expressed at the ratios of 1∶10, 1∶1 and 10∶1, the EC50 values of ACh were 91.2 μmol/L, 104.4 μmol/L and 130.6 μmol/L, respectively, while the IC50 values of α-CTx RegⅡA were 40.2 nmol/L, 36.4 nmol/L and 42.3 nmol/L, respectively.For α3β4 nAChR at the ratios of 1∶10, 1∶1 and 10∶1, the EC50 values of ACh were 44.0 μmol/L, 110.0 μmol/L and 230.0 μmol/L, respectively, while the IC50 values of α-CTx RegⅡA were 226.8 nmol/L, 71.5 nmol/L and 49.4 nmol/L, respectively.CONCLUSION:The results imply that the α3 and β4 subunit stoichiometry can change the structure and pharmacological activity of α3β4 nAChR, but the stoichiometry of α3 and β2 subunits has no effect on α3β2 nAChR.

Objective: To investigate the age related changes in cervical range of motion (CROM) and its relationship with cervical spondylosis in school students aged 12-18 in Nanyang City, to provide reference for prevention, early diagnosis and treatment evaluation of cervical spondylosis. Methods: Stratified sampling was adopted in 13 counties and districts of Nanyang City and 890 students aged 12-18 were assessed for CROM using the Coda Motion Analyzer. SPSS 19.0 was used to data analyze. Results: A decreasing trend was observed in CROM among boys and girls aged 12-18 years in Nanyang. For boys aged 15 and 18 years old, higher anterior flexion ( t =2.02, 2.70), posterior extension ( t =2.01, 2.81), left flexion ( t =3.51, 2.99), right flexion ( t =5.07, 2.66), sinistral ( t =2.28, 2.92) and dextral ( t =2.91,3.60) were found compared with younger age groups ( P <0.05). Similar findings were found in girls aged 15 and 18-years old [anterior flexion ( t =2.38, 2.20), posterior extension ( t =2.09,2.02), left flexion ( t =2.33, 2.55), right flexion ( t =7.34, 4.60), sinistral ( t =3.73, 2.35) and dextral ( t =2.31, 3.99, P <0.05). Except for the right flexion, the CROM of boys in was higher than that of girls at the same age group. The prevalence of cervical spondylosis showed an increasing trend (boys: χ 2 trend =13.93, girls: χ 2 trend =12.87, P <0.05). Except for 14-year-old group, the prevalence of cervical spondylosis in girls was higher than that in boys, with significant differences observed in 15 and 17-year-old groups ( χ 2=10.35, 9.64, P <0.05). Conclusion With the increase of age, the CROM of male and female students shows a downward trend in general. The prevalence of cervical spondylosis increases with the decrease of CROM. CROM measurement is conducive to the prevention, early diagnosis and treatment of juvenile cervical spondylosis.

Objective:To compare the efficacy of percutaneous vertebroplasty (PVP) in the treatment of osteoporotic lumbar compression fracture (OLCF) via the approach through midpoint transverse process-transition zone of articular process and the unilateral transpedicular approach.Methods:A prospective cohort study was conducted to analyze the clinical data of 794 patients with OLCF treated in Honghui Hospital affiliated to Xi′an Jiaotong University School of Medicine from January 2017 to December 2019. The patients were divided into transitional-zone puncture group (400 patients, 400 vertebrae) and pedicle puncture group (394 patients, 394 vertebrae) according to the envelope method. The transitional-zone puncture group was treated with PVP via the approach through midpoint transverse process-transition zone of articular process, and the pedicle puncture group was treated with PVP via the unilateral transpedicular approach. The operation time and radiation dose were documented. The visual analogue score (VAS) and Oswestry dysfunction index (ODI) were evaluated before operation and at 1 day, 3 months, 1 year after operation. The cement distribution and the incidence of complications such as cement leakage, re-fracture of the injured vertebra, spinal cord nerve injury and facet joint injury were detected.Results:The patients were composed of 270 males and 524 females, at the age of 68.9-78.5 years [(73.7±4.8)years]. All patients were followed up for 12-14 months [(13.4±0.8)months]. The operation time and radiation dose in transitional-zone puncture group were reduced compared with pedicle puncture group ( P<0.01). There was no significant difference in VAS and ODI between the two groups before operation (all P>0.05). The VAS between transitional-zone puncture group [(2.1±0.9)points, (2.3±1.1)points, (2.7±1.3)points] and pedicle puncture group [(2.3±0.7)points, (2.5±0.9)points, (2.9±1.1)points] was obviously reduced from that before operation (all P<0.01), significantly different at 1 day, 3 months, 1 year after operation ( P<0.05 or 0.01). The ODI between transitional-zone puncture group (14.3±1.8, 13.6±3.4, 11.3±4.4) and pedicle puncture group (25.5±5.7, 20.7±6.3, 20.6±6.9) was significantly different at 1 day, 3 months, 1 year after operation (all P<0.01), and all were obviously reduced from that before operation (all P<0.01). With regard to the cement distribution, the number of bilaterally cemented vertebrae in transitional-zone puncture group (324) was more than that in pedicle puncture group (94) ( P<0.01). The incidence of cement leakage, re-fracture of the injured vertebra and facet joint injury was 8.25%(22/400), 0.00%(0/400) and 3.25%(13/400) in transitional-zone puncture group, significantly different from 20.81%(82/394), 2.03%(8/394) and 9.90%(39/394) in pedicle puncture group ( P<0.05 or 0.01). There was no significant difference in spinal cord nerve injury between the two groups ( P>0.05). Conclusion:For OLCF, PVP via the approach through the midpoint transverse process-transition zone of articular process and the unilateral transpedicular approach are both effective, but the former has advantages of shorter operation time, smaller radiation dose, greater dispersion of bone cement and lower incidence of cement leakage, re-fracture of the injured vertebra and facet joint injury.

Objective To investigate the prevalence of metabolic syndrome (MS) in 259 professional automobile drivers,and to put forward targeted suggestions on protection.Methods In October 2014,114 male bus drivers and 145 male taxi drivers in a transportation service company were enrolled as investigation group,and 121 non-operating male staff were enrolled as control group.Physical examination and a questionnaire survey were conducted for both groups,and the results were analyzed.Results The bus drivers and taxi drivers had significantly higher prevalence rates of MS than the non-operating staff (17.5％/13.1％ vs 3.3％,P＜0.05).The results of univariate logistic analysis showed that smoking (OR=2.58,95％CI 1.14～5.88),exercise (OR=0.21,95％CI 0.10～0.43),meal time (OR=0.27,95％CI 0.13～0.59),and a family history of chronic diseases (OR =2.26,95％ CI 1.13～4.50) were associated with MS,and each independent variable showed significant differences between groups (P＜0.05).Multivariate logistic regression analysis showed that with age remaining the same,smoking was the risk factor for MS in professional automobile drivers (OR=5.25,95％CI 2.00～13.80),and meal time(20～40 min)(OR=0.20,95％CI 0.09～0.44)and exercise (OR=0.13,95％CI 0.06～0.30)were protective factors against MS.Conclusion Professional automobile drivers have a higher prevalence rate of MS than non-operating staff,which should be taken seriously by working personnel.

Objective To investigate the changes of short chain fatty acids (SCFA) induced by tacrolimus (FK506) in rats and evaluate its effect on blood glucose levels. Methods Ten SD rats were divided into the FK506 group and control group (n=5 in each group). In the FK506 group, the rats were received a subcutaneous injection of FK506 (3 mg/kg) +sunflower oil solution containing 10% ethanol daily for consecutive 4 weeks. In the control group, the rats were received a subcutaneous injection of an equivalent amount of sunflower oil solution containing 10% ethanol for consecutive 4 weeks. During the drug injection period, the body mass of rats was measured every week in two groups. After the drug injection period, blood glucose level, SCFA content in the blood and feces samples were measured in two groups. Results Compared with the control group, the relative body mass of rats in the FK506 group was significantly lower at the 2nd, 3rd and 4thweeks (all P<0.01). Compared with the control group, the blood glucose levels of rats in the FK506 group were significantly increased at 0, 30, and 60 min after giving glucose (P<0.01-0.05). Compared with the control group, the contents of acetic acid, propionic acid, isobutyric acid, butyric acid, isovaleric acid and valeric acid in the feces sample were significantly lower in the FK506 group (P<0.01-0.05). Conclusions FK506 can upregulate the blood glucose level in rats, which is probably induced by the decrease of SCFA content in rat feces.
