Objective: To investigate the attitude and behaviors towards tobacco control among civil servants in smoke-free governments of Ningbo City, so as to provide insights into the construction of smoke-free governments. Methods: Ten governments were randomly sampled from city-level and county/district-level smoke-free governments in Ningbo City using a stratified random sampling method, and 10 civil servants were sampled from each government using a convenient sampling method. Participants' demographics, attitude and behaviors towards tobacco control and second-hand smoke exposure were collected using a self-designed questionnaire and descriptively analyzed. Results: A total of 1 100 civil servants were recruited, including 466 men (42.36%) and had a mean age of (39.02±9.38) years. There were 1 005 participants favoring “civil servants should refuse smoking firstly” (91.36%), 1 058 participants favoring “governments should build a smoke-free environment firstly” (96.18%), 1 075 participants favoring “smoking should be completely banned in any indoor public places” (97.73%), 913 participants thinking that smoking should be completely banned in any indoor public places (83.00%) and 813 participants thinking that tobacco control regulations are implemented satisfactorily in their workplaces (73.91%). The overall prevalence of current smoking was 11.91% among participants, and the prevalence of current smoking was 28.11% among male participants. Among all current smokers, 84 attempted to quit smoking (64.12%), and 89 had willingness or plans to quit smoking (67.94%). The proportion of second-hand smoke exposure in workplaces was 40.97% among non-smokers in the past one week. Conclusions The civil servants in Ningbo City has correct awareness of smoke-free governments, active attitudes towards tobacco control and low prevalence of smoking. However, smoke-free regulations remain to be improved and long-term tobacco control mechanisms remain to be created in governments in Ningbo City

Objective:To establish the model of rats with UC by 2,4,6 trinitrobenzene sulfonic acid ( TNBS)/ethanol to understand the changes of IL-17,IL-23,TGF-β1,IFN-γin pathogenesis of ulcerative colitis (UC) and the impacts of mesalazine,mont-morillonite powder and clostridium on that.Methods:85 rats were divided randomly into 6 groups including the model ,mesalazine, montmorillonite,clostridium,mesalazine combined with montmorillonite powder group (15 rats per group ) and an additional control group of 10 normal rats.TNBS/ethanol was used to establish the model of rats with UC.The dosage of model, mesalazine, montmorillonite powder ,clostridium and mesalazine combined with montmorillonite powder were converted by surface area of rat and given to the rats by gastric-tube daily.All rats were executed at the 12th day of the molding and treatment ,and the blood and colon samples were collected.The content of IL-17,IL-23,TGF-β1,IFN-γwas measured in the blood by the ELISA method.The different changes of the four cytokines were compared separately.Results: ( 1 ) TNBS/ethanol was used to establish the model of rats with UC.The obvious inflammation can be observed on distal colon of rats by pathologic sections of HE stained .(2) The levels of plasma IL-17,IL-23 and IFN-γin the model,mesalazine,montmorillonite,clostridium and mesalazine combined with montmorillonite powder group were higher than ones in the control gruop (P<0.05),meanwhile,the levels of plasma TGF-β1 are lower (P<0.05).3.Comparing with the model group,the levels of plasma IL-17,IL-23 and IFN-γin the mesalazine,montmorillonite,clostridium and mesalazine combined with montmorillonite powder group were lower , and the levels of TGF-β1 were higer.The differences have statistic significative ( P<0.05).(4)Comparing the efficacy of treatment among mesalazine ,montmorillonite powder,clostridium and mesalazine combined with montmorillonite powder ,mesalazine and mesalazine combined with montmorillonite powder gets the best results ( P<0.05 ).The efficacy between montmorillonite powder and clostridium is similar.Conclusion:(1) TNBS/ethanol can be used to establish the model of rats with UC and can be successfully approved by the measurement of symptoms and pathologic investigation .(2)The IL-17,IL-23 and IFN-γare very active higher in the blood of rats with experimental ulcerative colitis induced by TNBS /ethanol, and have a positive correlation with inflammation.The TGF-β1 is in decrease in the blood of rats with colitis , and has a Negative Correlation with inflammation.(3)Mesalazine,montmorillonite powder,clostridium and mesalazine combined with montmorillonite powder may renovate the damage of inflammatory tissues of rats with experimental ulcerative colitis , and relieve the symptom of inflammation by reducing exudation of proinflammatory cytokines IL-17, IL-23 and immune regulatory cytokines IFN-γby producing the exudation of proinflammatory cytokines TGF-β1 to be good for recovery of UC.

Objective To study the change of levels of IL-6,IL-17,IL-23,IL-8,TNF-α and IFN-γ and their clinical significance on children with different types of Henoch-Schonlein purpura (HSP) Methods The blood specimens of 180 children with HSP as disease group and 30 health children as normal group were collected respectively.Disease group included 30 children at acute stage and 30 at convalescence stage of primary abdominal type,30 at acute stage and 30 at convalescence stage of primary non-abdominal type,30 at acute stage of secondary abdominal type,and 30 at acute stage of secondary non-abdominal type.The plasma levels of IL-6,IL-8,IL-17,IL-23,TNF-α and IFN-γ in the two groups were measured by ELISA method for comparison and analysis.Results The plasma levels of IL-6,IL-8,IL-17,IL-23 and TNF-α in disease group were higher than those in the normal group (P＜0.05).Those levels in the children at acute stage and of primary group were also found to be higher than those at convalescence stage (P＜0.05) and of secondary group (P＜0.05) respectively.Comparison of IL-6,IL-8,IL-17,IL-23 and TNF-α between abdominal type and the non-abdominal type had no significant difference (P＞0.05).The plasma level of IFN-γ in disease group was lower than those in normal group (P＜0.05).The levels of IFN-γ in the children at acute stage and of primary group were lower than those at convalescence stage (P ＜0.05) and of the secondary group (P ＜0.05) Comparison of IFN-γ between abdominal type and non-abdominal type had no significant difference (P＞0.05) Conclusions The plasma levels of IL-6,IL-8,IL-17,IL-23,TNF-o,IFN-γ show obvious changes in children with HSP,which suggests that the changes of cytokines are associated with the pathogenesis and prognosis of Henoch-Schonlein purpura.

Objective:To retrospectively analyze the effect of hormone combined with cerebral glycoside carnosine and dehydration drugs in traumatic optic neuropathy (TON) patients.Methods:The enrolled 215 TON patients in our hospital from February 2014 to September 2021 were randomly divided into the combination group ( n=143) and routine group ( n=142). The baseline data, visual acuity recovery before and after treatment and adverse reactions of each group were compared. Univariate analysis was conducted to analyze the differences in indicators of good prognosis and visual acuity improvement between the two groups. Results:The effective rate of vision recovery in the combination group was significantly increased than that in the routine group ( P<0.05). After treatment, the intraocular pressure and visual field defect in the combination group were significantly decreased than those in the routine group ( P<0.05). Univariate subgroup analysis showed that there were statistically significant differences between TON patients with age ≤40 years, residual light sensation after injury, visit time ≤24 h, and VEP not extinguished with combined treatment of hormone, brain glycoside carnotin and dehydrating drugs and the routine group ( P<0.05). Univariate subgroup analysis showed that TON patients with optic canal fracture without optic nerve swelling and tortuosity had a good prognosis after treatment with combined hormone, cerebral glucoside carnosine and dehydration, which was statistically different from that in the routine group ( P<0.05). Conclusions:Brain glycosides carnosine and dehydration therapy on the basis of combined hormone a prednisolone sodium succinate treatment can improve vision in TON patients, lighten the optic nerve injury, will not increase the occurrence risk of adverse reactions, and have higher security. It is necessary to focus on high-risk patient over 40 years old, more than 24 h of treatment time, VEP extinction, optic nerve swelling poor efficacy. It is worthy of clinical promotion.

Acromicric dysplasia(AD) is a rare skeletal dysplasia characterized by severe short stature, short hands and feet, normal intelligence, mild facial dysmorphism, and radiological characteristics. The clinical data and genetic test results of one patient with AD in our hospital were analyzed, and the clinical characteristics of this case were summarized. The main manifestations of the child were short stature, short hands and feet, mild facial dysmorphism, short and stubby metacarpals and phalanges on hand X-ray. One mutation, FBN1: c.5141T>G(p.Met1714Arg), was identified in this child, the mutation is inherited from her short mother and grandfather. AD is a rare congenital skeletal dysplasia disorder associated with mutations in the FBN1 gene. It conforms to the pathogenesis of autosomal dominant genetic disease.

Objective To observe value of echocardiographic evaluation on infants with pulmonary atresia and intact ventricular septum(PA/IVS)for surgical decision and post operation right ventricle(RV)development.Methods Forty-six PA/IVS infants who underwent pulmonary valve(PV)annuloplasty(group A,n=25),PV annuloplasty and RV outflow tract reconstruction with/without additional systemic-to-pulmonary artery shunt(group B,n=15),and systemic-to-pulmonary artery shunt and atrial septal enlargement(group C,n=6)were retrospectively enrolled.Status of RV developments were compared among groups before operation as well as 1 and 6 months after operation.Results The presentation age in group B was younger than,while in group C was older than that in group A(both P＜0.05).Before operation,tricuspid valve(TV)annulus diameter,TV annulus Z-score and TV/mitral valve(MV)annulus ratio in groups B and C were both smaller than those in group A(all P＜0.05),whereas RV/left ventricle(LV)longitudinal diameter ratio in group B was larger and PV annulus Z-score in group C was smaller than those in group A(both P＜0.05).Meanwhile,preoperative PV annulus Z-score and RV/LV longitudinal diameter ratio in group B were both larger than those in group C(both P＜0.05).One month after operations,TV annulus diameter,TV annulus Z-score and TV/MV annulus ratio in group B and C,as well as PV annulus diameter,PV annulus Z-score and RV/LV longitudinal diameter ratio in group C were all smaller than those in group A(all P＜0.05),while PV annulus diameter,PV annulus Z-score and RV/LV longitudinal diameter ratio in group C were all smaller than those in group B(all P＜0.05).Six months after operations,no significant difference of TV annulus diameter,PV annulus diameter,PV annulus Z-score,TV/MV annulus ratio nor RV/LV longitudinal diameter ratio was found between group A and B(all P＞0.05),but the above indexes in group C were all lower than those in group A and B(all P＜0.05).Besides,no significant difference of TV annulus Z-score was found between group A and B(P＞0.05),which were lower in group C than in group A(P＜0.05).Conclusion Echocardiographic evaluation on PA/IVS infants was helpful to establishment of forward blood flow from RV to pulmonary arteries in time,hence promoting RV development.

AIM: To evaluate the binocular visual function in high myopia patients after the implantation of implantable collamer lens(ICL)V4c.METHODS: A total of 35 cases(70 eyes)that received binocular ICL implantation at our hospital from May 2019 to May 2021 were enrolled in this prospective study. Binocular full-range visual acuity, contrast sensitivity, stereopsis, mesopic vision and glare sensitivity, and monocular wavefront and the quality of vision questionnaire were assessed before the surgery and at 1 mo postoperatively.RESULTS: At 1 mo postoperatively, 35 cases(100%)had binocular uncorrected distance visual acuity(UDVA)≤0.00(LogMAR), 16 cases(46%)had binocular UDVA≥preoperative corrected distance visual acuity(CDVA). Binocular UDVA and uncorrected intermediate visual acuity(UIVA,80 cm)were improved compared to preoperative CDVA and distance-corrected intermediate visual acuity(DCIVA,80 cm)(all P<0.05).While there were no differences in the binocular postoperative UIVA(60 cm)and preoperative DCIVA(60 cm),and uncorrected near visual acuity(UNVA,40 cm)and preoperative distance-corrected near visual acuity(DCNVA,40 cm)(all P>0.05). The binocular contrast sensitivity was significantly improved postoperatively(P=0.001), and the postoperative binocular mesopic vision, glare sensitivity(no glare/glare)and binocular stereopsis(5 m/40 cm)had no differences(all P>0.05). The postoperative total higher-order aberration, trefoil aberration, coma and spherical aberration were increased, besides the median of total coma in the right eye with a pupil diameter of 3.0 mm was decreased after surgery. The mean total score of quality of vision questionnaire was significantly increased from 54.87 preoperatively to 80.92 after implantation(P<0.05), with high satisfaction and no obvious visual disturbance in patients.CONCLUSION: Although the monocular high-order aberrations increased in the early stage after ICL V4c binocular implantation in patients with high myopia, the binocular visual function was improved.
