Objective To study the neuropsychological behavior development of preterm infants and low birth weight infants,and to provide a reference to the early prevention and intervention on developmental retardations.Methods A total of 101 preterm infants and/or low birth weight infants received the infant development test of 0 ～ 6 year-old children intelligence developmental scale for neurological development and autism behavior checklist(ABC).Results 25 boys and 5 girls suffered from different psychological mental disorders.The occurrences were as follows:10 cases with mental retardation,9 cases with the language development delay,9 cases with motor retardation,1 case with cerebral palsy and 1 case with autism spectrum disorder.The incidence of intelligence problems were that language retardation (18.9％),the fine motor (16.8％),the adapative ability (12.6％),social action (9.5 ％) and the motor delay (3.2％).There were significant differences in the scores of social communication(x2=8.88,P=0.003),adaptive ability(x2=7.41,P=0.007),the fine motor(x2 =6.22,P=0.01) and total developmental quotient(x2 =5.58,P=0.02) between city children'and rural area.The behavioral problems more consisted in self-care ability and language retardation.Conclusion Preterm infants and low birth weight infants are exposed to language,fine motor,adaptive and communication ability problems,especially the children living in country.It is necessary to improve the early education and intervention for the rural preterm infants and low birth weight infants.

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 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.

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.

Background: Percutaneous radiofrequency ablation (RFA) is a first-line treatment for very-early-stage hepatocellular carcinoma (HCC), whereas the efficacy of percutaneous microwave ablation (MWA) for very-early-stage HCC remains unclear. The purpose of this study was to clarify this issue by comparing the safety and efficacy of percutaneous MWA with percutaneous RFA in treating very-early-stage HCC. Methods: Clinical data of 460 patients who were diagnosed with very-early-stage HCC and treated with percutane-ous MWA or RFA between January 2007 and July 2012 at the Eastern Hepatobiliary Surgery Hospital, The Second Mili-tary Medical University, in Shanghai, China were retrospectively analyzed. Of these 460 patients, 159 received RFA, 301 received MWA. Overall survival (OS), recurrence-free survival (RFS), local tumor progression (LTP), complete ablation, and complication occurrence rates were compared between the two groups, and the prognostic factors associated with survival were analyzed. Results: No significant differences were observed between the two groups in terms of the 1-, 3-, or 5-year OS rates (99.3%, 90.4%, and 78.3% for MWA vs. 98.7%, 86.8%, and 73.3% for RFA, respectively;P= 0.331). Furthermore, no signif-icant differences were observed between the two groups in terms of the corresponding RFS rates (94.4%, 71.8%, and 46.9% for MWA vs. 89.9%, 67.3%, and 54.9% for RFA, respectively;P= 0.309), the LTP rates (9.6% vs. 10.1%,P= 0.883), the complete ablation rates (98.3% vs. 98.1%,P= 0.860), or the occurrence rates of major complications (0.7% vs. 0.6%,P= 0.691). By multivariate analysis, LTP, antiviral therapy, and treatment of recurrence were independent risk fac-tors for OS (P < 0.001), and the alpha-fetoprotein level was an independent prognostic factor for RFS (P= 0.002). Conclusions: MWA is as safe and effective as RFA in treating very-early-stage HCC, supporting MWA as a first-line treatment option for this disease.

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 investigate effects of Baishile Capsules on cAMP-CREB-BDNF signal pathway about hippocampal neurogenesis in model rats with chronic unpredicted stress depression. Methods SD rats were randomly divided into blank group, model group, fluoxetine hydrochloride group, and Baishile Capsules high, medium, and low dose groups. Chronic stress depression rat model was established by chronic and mild unpredictable stressors. All groups were given relevant medicine for 21 days. The open-field test, sugar consumption experiment, place navigation test, and space searching experiment were used to detect behavior changes of the rats. ELISA was used to detect content of corticosterone in plasma. The protein expressions of PKA, BDNF, and CREB were detected by immunohistochemical method. Results Compared with model group, Baishile Capsules high dose and medium dose groups could remarkably increase the number of vertical and horizontal activities and 1% sucrose partial eclipse. Platform latency and target quadrant searching time decreased significantly in Baishile Capsules high dose group (P<0.05), and content of corticosterone in plasma increased obviously (P<0.05) in Baishile Capsules all dose groups. Protein expressions of PKA, CREB, and BDNF in hippocampal DG and CA3 area increased significantly (P<0.05) in Baishile Capsules high dose group. Conclusion Baishile Capsules can promote hippocampal neurogenesis through the cAMP-CREB-BDNF signal pathway and realize anti-depression effect.

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.
