Objective:To investigate the incidence of asthma and the characteristics of acute attacks in children aged 3-14 in different administrative areas of Wuxi, and to analyze the correlation of asthma with the outdoor environmental factors.Methods:A total of 10 175 children aged 3-14 were randomly selected from 5 different administrative regions in Wuxi City, Jiangsu Province for childhood asthma epidemiological survey from January to December in 2017.Results:The complete questionnaires were collected from 8 318 children with a response rate of 81.70%.There were 6 734 valid questionnaires.Asthma occurred to 259 children, and the prevalence rate was 3.84%.The prevalence of asthma in male and female children was 4.89% (163 cases) and 2.82% (96 cases), respectively.The ratio of male patients to female patients was 1.70∶1.00, and the difference was significant ( χ2=19.72, P<0.01). Children were most prone to suffer from asthma attacks at the turn of seasons (87/259 cases, 33.59%). The frequency of asthma was the lowest from June to August (9/259 cases, 3.47%). Among 244 cases attacked by acute asthma, the prevailing time period of acute attacks was irregular in 88 patients (36.07%), bedtime in 64 cases (26.23%). In different regions of the city, the lowest prevalence rate of asthma was found in Binhu District (50/1 830 cases, 2.73%), the highest prevalence rate of asthma was found in Xinwu District (71/1 502 cases, 4.72%), the difference between the highest and lowest prevalence rates of asthma was significant ( χ2=13.19, P<0.05). In terms of the air quality in different admi-nistrative regions of Wuxi, the nitrogen dioxide (NO 2) concentration, the carbon monoxide (CO) concentration, PM 10 and PM 2.5 in Binhu District were lower than other 4 regions.In different seasons in Wuxi city, the sulfur dioxide(SO 2) concentration, the NO 2 concentration, the CO concentration, PM 10 and PM 2.5 from June to August were significantly lower than those in other months.The prevalence of asthma in children in different administrative districts of Wuxi was weakly positively correlated with the SO 2 concentration, the NO 2 concentration and PM 10 ( r=0.10, P<0.01; r=0.22, P<0.01; r=0.06, P<0.01, respectively). The prevalence of asthma was weakly negatively associated with the ozone(O 3) concentration ( r=-0.06, P<0.01). Acute asthma attacks were weakly positively correlated with the SO 2 concentration ( r=0.22, P<0.01), the NO 2 concentration ( r=0.28, P<0.01), the CO concentration ( r=0.23, P<0.01), PM 10 ( r=0.18, P<0.01) and PM 2.5 ( r=0.18, P<0.01), and weakly negatively correlated with the O 3 concentration ( r=-0.40, P<0.01). Conclusions:The prevalence of asthma in Wuxi is higher in boys than in girls, and the frequency of asthma attacks is related to the season.The SO 2, NO 2, CO, PM 10, PM 2.5 and O 3 concentration affect the prevalence and acute attacks of asthma.

OBJECTIVETo investigate the expression and significance of CD151 in pituitary adenomas.

METHODSThirty-six pituitary adenomas were collected immediately after surgery together with five normal pituitary tissue. Real time-PCR, Western blot and immunohistochemistry analysis were performed to detect the expression of CD151 mRNA and protein in thirty-six pituitary adenomases and five normal pituitary tissues.

RESULTSThe expression of CD151 in all pituitary adenomases was observed to be significantly higher than that in normal pituitary tissues by Western blot, real time PCR, and immunohistochemistry analysis (P < 0.01). The expression levels of protein and mRNA in invasive pituitary adenomas were much higher than those in non-invasive pituitary adenomas (P < 0.01).

CONCLUSIONThe results suggested that the expression of CD151 was closely correlated with malignant degree of pituitary adenomas, which indicated the expression of CD151 was intimately correlated with occurrence and development of pituitary adenomas. Detecting CD151 might be a vital index to predict prognosis of pituitary adenomas.

OBJECTIVETo study a feasible method of measuring right ventricular pressure by catheterization in mice.

METHODSMeasuring the right ventricular pressure and the pulmonary artery pressure by homemade PE pipe through venous cannula in external jugular vein, using catheterization in mice with powerlab multimodal biometric signal recording system.

RESULTSForty-six out of 51 mice were experimented with this method smoothly and got a total success rate of 90.2%. Thirty of 33 normal mice and 16 of 18 mice with pulmonary arterial hypertension (PAH) were catheterized successfully. The right ventricular pressure were as follow: systolic blood pressure: (23.4 +/- 5.7) mmHg in normal group vs (32.2 +/- 2.8) mmHg in mice with PAH, diastolic blood pressure: (3.7 +/- 2.6) mmHg vs (3.8 +/- 2.0) mmHg, mean pressure: (12.0 +/- 3.7) mmHg vs (14.9 +/- 2.3) mmHg. After autopsy for those 5 failed cases, we found that 2 cases were into the inferior vena cava, another 2 cases pierced the right auricle and the last one punctured the axillary vein into the chest wall.

CONCLUSIONMeasuring the right ventricular pressure through venous cannula in external jugular vein with homemade PE pipe in mice gets not only a high success rate but also help to save time. Moreover, this method can be popularized easily. It is a good and feasible method for measuring right ventricular pressure in mice.

Objective To evaluate the efficacy of moxifloxacin-based triple therapy combined with rebamipide for Helicobacter pylori (Hp) eradication in type 2 diabetic patients.Methods Two-hundred age and sex matched type 2 diabetic patients with Hp infection and accompanied by gastrointestinal symptoms were assigned into rebamipide group (n =100) and placebo group (n =100).Both groups received moxifloxacin-based triple therapy for 10 d to eradicate Hp.Rebamipide was administrated in rebamipide group and placebo was administrated in placebo group for 30 d.All patients proceeded 14C-urea breath test (14C-UBT) hefore and 7-8 weeks after eradication therapy.The blood sugar indices,gastrointestinal symptom scores and Hp eradication rates were measured and compared.Those who had gained successful Hp eradication in both groups proceeded 14 C-UBT again 12 months after eradication therapy,and the re-infection rates of both groups were compared.Results There were no significant differences in the average fasting glucose,postprandial glucose and HbAlc levels between the rebamipide group and the placebo group before and after therapy (P ＞ 0.05),the gastrointestinal symptoms of the rebamipide group were improved more markedly than those of the placebo group after therapy (Rome Ⅲ Criteria,2.1 ± 0.9 vs.4.4 ± 0.7,P ＜ 0.01).The Hp eradication rate with both intention-to-treat (ITT) and per protocol (PP) analysis of the rebamipide group were higher than that of the placebo group [86.0％ (86/100) vs.73.0％ (73/100),P ＜ 0.05 and 92.5％ (86/93) vs.76.8％ (73/95),P ＜ 0.01].The re-infection rates with both ITT and PP analysis of those who had successful eradication in rebamipide group were lower than that in placebo group [19.8％ (17/86) vs.35.6％ (26/73),P＜0.05and20.5％ (17/83) vs.36.6％ (26/71),P＜0.05].Conclusions Moxifloxacin-based triple therapy combined with rebamipide has a more beneficial effect on Hp related symptoms,a higher Hp eradication rate and a lower Hp re-infection rate for type 2 diabetic patients.

OBJECTIVETo explore methods of treating middle and distal tibia nonunion with the treatment of advanced bone graft combined with locking compression plate.

METHODSFrom January 2011 to December 2012, 12 patients with middle and distal tibia nonunion were treated with advanced bone graft combined with locking compression plate. Among patients, there were 8 males and 4 females aged from 20 to 69 with an average of 47 years old. The time from first injuries to bone nonunion was from 9 months to 5 years, avergaed 19 months. Four cases were treated with external fixation, 6 cases were treated with plate fixation, 2 cases of 12 patients occurred broken of plate and nail. Eleven patients were non-infective bone nonunion and 1 patient was infective bone nonunion. Preoperative X-ray and CT showed all patients had sequestration and formation of ossified bone with different degrees. Operative time, blood loss, wound healing were observed, fracture healing time was evaluated by postoperative X-ray. Johner-Wruhs scoring standards was used to evaluate ankle joint function after operation at 10 months.

RESULTSOperative time ranged from 90 to 185 min with an average of (125.00±20.15) min; blood loss ranged from 225 to 750 ml with an average of (415.00±120.00) ml. All patients were followed up from 10 months to 2.5 years with an average of 1.5 years. Postoperative X-ray showed bone union was formed around fracture after operation at 4 months in all patients, 3 cases obtained bone healing within 6 months after operation, 9 cases obtained from 8 to 12 months. No infection, injury of nerve and vessles, and broken of plate and nail were ocurred. According to Johner-Wruhs scoring at 10 months after operation, 10 cases obtained excellent results, 1 good and 1 moderate.

CONCLUSIONAdvanced bone graft combined with locking compression plate, which can build fracture multi-point supporting based on full compression of bone nonunion to get effective fixation, is an effective method in treating middle and distal tibia nonunion.

Objective To evaluate the clinical efficacy of tacrolimus and cyclophosphamide (CTX) on lupus nephritis.Methods The clinical trials on treatment of lupus nephritis with tacrolimus and CTX published before October 2012 were searched at Cochrane library,PubMed,OVID,Wanfang database,Chinese Journal full-text Database,Chongqing Weipu Database by using the methods of Cochrane systematic review.At the same time the information from related journals,professional data and network were hand-searched.The homogeneous evaluation was performed by Meta-analysis.Statistical analysis of clinical data was performed by using Stata11 software.Results A total of 4783 reports were found,while only 9 papers (8 randomized controlled trials and 1 cohort study) met the inclusion criteria.Tacrolimus group got better complete remission ratio (Z =4.05,P ＜ 0.01),similar partial remission ratio (Z =0.44,P =0.661),and better overall remission ratio (Z =4.29,P ＜ 0.01) as compared with CTX group.There were no significant differences between tacrolimus group and CTX group in the incidence of infection (Z=1.75,P=0.081),renal damage (Z=0.88,P=0.38) and abnormal glucose metabolism (Z =1.91,P =0.070).Side effects such as liver function impairment (Z =2.65,P＜0.01),gastrointestinal discomfort (Z=2.31,P＜0.05),menstrual disorders (Z=3.88,P＜0.01),bone marrow suppression (Z =3.29,P ＜ 0.01) in tacrolimus group were lower than those in CTX group.Conclusions Compared with CTX,tacrolimus has better complete remission ratio and overall remission ratio,with less side-effects in the treatment of lupus nephritis.However,large scale,multicenter,well-designed clinical trials should be adopted to further confirm the conclusions.

Objective To investigate the effects and mechanism of huoxuexiaoying tablet on experimental goiter of rats. Methods The rats were randomly divided into six groups: the control, the model control group, huoxuexiaoying tablet at different doses,and the sodium levothyroxine group ( Euthyrox group) . Except for the rats in the control,the rats in other groups were given with propylthiouracil (20 mg·kg-1 ·d-1 ) by intragastric ( i. g. ) administration every day for 60 days. Meanwhile, some rats were treated with huoxuexiaoying tablet at low (4. 4 g·kg-1·d-1),middle (8. 8 g·kg-1·d-1) and high dose (17. 6 g·kg-1 ·d-1 ) orally,and those in the Euthyrox group were given with 7. 8μg·kg-1 ·d-1 Euthyrox by i. g. administration. The rats in the control group were administrated with the same volume of saline (N. S). After 60 days of treatment,the rats were sacrificed,the organ indexes of thyroid and pituitary and the levels of free triiodothyronine ( FT3 )、free thyroxin ( FT4 ) and thyroid stimulating hormone(TSH) in serum,were tested. The expression of basic fibroblast growth factor(bFGF),transforming growth factor-β( TGF-β) and B-cell lymphoma 2 gene ( Bcl-2 ) were examined by immunofluorescence. Results Compared with the model,organ indexes of thyroid were significantly reduced by huoxuexiaoying tablet at three doses (P<0. 05),but not for the pituitary (P>0. 05). The levels of FT3 and FT4 were in a elevating trend,but TSH decreased with no significance (P>0. 05). The morphological structure of thyroid was greatly improved by huoxuexiaoying tablet in comparison with the model. In which the gland dilated,thyroid follicular restored to moderate size,epithelia were cubic or flattened and follicular cavity filled with abundant glial. The expression of bFGF and Bcl-2 decreased significantly (P<0. 01) while TGF-β expression increased notably (P<0. 01). Conclusion Huoxuexiaoying tablet has a great anti-goiter effect,the mechanism of which may be related to promoting thyroid cells apoptosis and inhibiting thyroid cells proliferation.

This study is to report the study of protective effects of myricitrin against oxidative stress-induced apoptosis of vascular endothelial cells and the investigation of the possible mechanisms of action of myricitrin. The model of H2O2-induced apoptosis of vascular endothelial cells was used to determine the protective effects of myricitrin. The levels of LDH, MDA and the activities of SOD, NO were measured using the respective kits. The H2O2-induced apoptosis of vascular endothelial cells was detected using MTT reduction, TUNEL assay, JC-1 and ROS staining. The activation of Caspase-3 was also measured by fluorometry. The expression of apoptosis-related proteins was determined with Western blotting assay. Myricitrin had significant protective effects against H2O2-induced apoptosis of vascular endothelial cells in a time- and dose-dependent manner. The results show that myricitrin could attenuate H2O2-induced decrease in the activities of SOD (P < 0.01). Myricitrin could decrease the levels of LDH, MDA and increase cell viability and the mitochondrial membrane potential (P < 0.01). Myricitrin had protective effects in a dose-dependent manner between 32 micromol x L(-1) to 64 micromol x L(-1). Myricitrin pretreatment could attenuate H2O2-induced increase of p-ERK. Moreover, myricitrin pretreatment could up-regulate the expression of the anti-apoptotic protein Bcl-2, down-regulate the expression of the pro-apoptotic protein Bax, and decrease the expression of Caspase-3, 9. In conclusion, myricitrin had significant protective effects against H2O2-induced apoptosis of vascular endothelial cells. Myricitrin can enhance the activities of anti-oxidative enzymes and decrease the production of free radicals. The possible mechanisms of action of myricitrin are due to myricitrin-mediated inhibition of phosphorylation of the apoptosis signaling pathways-related kinase ERK, up-regulation of the expression of the anti-apoptotic protein, and down-regulation of the expression of the pro-apoptotic protein.

Objective To quantitatively assess severity of movement disability by analyzing physical activities recorded by an actigraph monitor in patients with neurology disorders.Methods Eighty-one patients with Parkinson' s disease(PD)and 61 patients with acute cerebral infarction(ACI)accompanying impaired upper limb motor function were included in the study.PD patients and ACI patients were treated using the international PD and ACI treatment guidelines,respectively.The patients were asked to wear an Actigraph monitor for 6 days before the treatment in both PD and ACI patient groups and at 24-38 days post-treatment in PD patients or at 28 days post-treatment in ACI patients.The recorded data was analyzed by power-law exponent(PLE)and detrended fluctuation analysis(DFA).Clinically,before and after the treatments,PD patients were evaluated using the conventional Unified Parkinson Disease Rating Scale (UPDRS),and ACI patients were evaluated by assessing upper limb motor function using Fugl-Meyer Assessment(FMA)and Functional Independence Measure(FIM).The correlation of the UPDRS scores with PLE was analyzed in PD patients,and the correlation of FMA or FIM with DFA in ACI patients.Results Both the UPDRS scores and the PLE values in PD patients were improved after the drug administration(UPDRS total:32.8 ± 16.2 and 28.8 ± 14.7,Z =2.080,P =0.038; UPDRS Ⅲ:18.6 ± 8.2 and 15.7±6.8,Z=2.155,P=0.031; PLE:0.98 ±0.25 and 0.82 ±0.21,Z=2.212,P=0.027,before and after the treatment,respectively).There were a linear correlation coefficient of 0.699 between the improvements of total UPDRS scores and the PLE values,and of 0.823 between the UPDRS Ⅲ and the PLE values.FMA,FIM scores and DFA were improved significantly than before treatment(FMA:12.39 ± 8.21 and 30.28 ±7.29,Z=3.016,P =0.004; FIM:8.98 ±7.29 and 13.21 ±7.6,Z =2.282,P=0.038; DFA:0.86 ±0.31 and 0.98 ±0.27,Z =2.360,P =0.036,before and after the treatment,respectively).It also showed linear correlations between the improvements of FMA scores and DFA(r =0.638),and between FIM scores and DFA(r =0.712,both P ＜0.05).There was no correlation between UPDRS scores and DFA values in PD patients,nor between FIM scores or FMA scores and PLE values in ACI patients.Conclusions Actigraph device can be used to monitor patients activity in movement disorders.Analysis of its PLE can provide a quantitative evaluation in PD while its DFA may provide useful specific assessment of impaired upper limb motor function in ACI patients.It can also be used in quantitatively assessing new drug efficacy.
