Objective To investigate the effects of Puerarin on the expression of hyperphosphorylated-tau (P_ ser404-tau) and choline acetyltransferase (ChAT) in hippocampus of Alzheimer's disease(AD) rats.Methods The rats were divided into sham-operation group, AD group and Puerarin treated group at randomly. The AD rat models were established by injecting amyloid-beta peptide(A?_ 25-35) into right amygdala. The sham-operation rats were injected with trifluoroacetic acid in the same location. The spatial memory function was observed by Y-maze. The protein expression of P_ ser404-tau and ChAT in hippocampus were detected by immunohistochemistry.Results (1)Compared with sham-operation group,the results of maze test were down in AD group and the number of P_ ser404-tau positive cells was significantly higher,while the number of ChAT positive cells was significantly lower (all P

Objective To investigate the effects of tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)on acute myocardial functional lesion after severe craniocerebral injury.Methods Sixty five examples with severe craniocerebral injury are collected in the 253th hospital of PLA from February in 2009 to May in 2012,of whom glasgow coma scale was low or equal to 8 points.They are examined creatine kinase-MB(CK-MB),cardiac troponin T(cTnT),TNF-αand IL-6 for correlative analysis while they are emer-gency treated at the same time.Results The myocardial function of the observe group examined results:CK-MB(198.63±37.72) U/L,cTnT(548.17±49.58)pg/mL;injury factors examined results:TNF-α(39.93± 18.88)ng/mL,IL-6(469.61 ±73.66)ng/mL.It both has evidently difference between the control group and the observe group and has obviously correlation between the my-ocardial function and injury factors of the observe group (P <0.01),and they were positively correlated.Compared TNF-α,IL-6 in observe group,CK-MB(r>0.911 4)and cTnT(r>0.942 1)had statistically significant difference.Conclusion TNF-αand IL-6 all participate in the process of the acute myocardial functional lesion after severe craniocerebral injury.The inchoate interference and treatment against TNF-αand IL-6 are possible to have inhibited the high expression of TNF-αand IL-6 in the blood and to improve the myocardial functional lesion after severe craniocerebral injury.

Objective To investigate the correlation between tumor necrosis factor (TNF)-α,interleukin (IL)-6,platelet activating factor (PAF) with the blood coagulation disorder in severe craniocerebral injury.Methods Collected 65 subjects (observation group) with severe craniocerebral injury from January in 2009 to June in 2012 with the trauma index ≥17 points,glasgow coma scale ≤ 10 points,combined with other parts of the injury and died in the emergency department were excluded.Examined platelet count (PLT),activated partial thromboplastin time (APTT),prothrombin time (PT),D-dimer (D-D),TNF-α,IL-6 and PAF meanwhile were emergency treated,selected the same period 43cases of health as control group,these indicators were compared.Results PLT in observation group was significantly lower than that in control group [(74.91 ± 30.70) × 109/L vs.(191.52 ± 23.31) × 109/L] (P ＜0.01),APTT,PT in observation group was significantly longer than that in control group [(69.44 ± 15.52) s vs.(22.47 ± 9.41) s,(30.37 ± 8.22) s vs.(9.57 ±4.53) s] (P ＜0.01),D-D,TNF-α,IL-6,PAF in observation group was significantly higher than that in control group[(1 934.92 ± 708.49) U/L vs.(105.78 ± 44.53) U/L,(39.93 ± 18.88) μg/L vs.(1.28 ±0.59) μg/L,(417.61 ±73.66) μg/L vs.(63.93 ±41.49) μ g/L,(16 359.91 ±4 321.92) ng/L vs.(3 823.45 ±529.72) ng/L](P＜0.01).PLT in observation group was negatively correlated with TNF-α,IL-6 and PAF (r =-0.929 2,-0.944 5,-0.932 4,P ＜ 0.01),APTT was positively correlated with TNF-α,IL-6 and PAF (r =0.910 2,0.932 7,0.978 6,P ＜0.01),PT was positively correlated with TNF-α,IL-6 and PAF (r =0.934 1,0.955 4,0.978 6,P ＜ 0.01),D-D was positively correlated with TNF-α,IL-6 and PAF (r =0.942 1,0.943 8,0.941 8,P ＜ 0.01).Conclusions TNF-α,IL-6 and PAF all participate in the process of the blood coagulation disorder in severe craniocerebral injury.The inchoate interference and treatment such as lessening stress responses and inflammation responses against TNF-α,IL-6,PAF is possible to improve the blood coagulation disorder in severe craniocerebral injury and to decrease the death rate of patients.

Objective To explore the difference of the impact with different hydrosalpinx pretreatment methods in vitro fertiliza-tion-embryo transfer ﹝ IVF-ET ﹞.Methods 160 patients with routine IVF-ET’s hydrosalpinx were random divided into two groups :the first 80 patients undergoing routine bolt blocking the fallopian tubes for the study group;the other 80 patients with rou-tine salpingectomy as control group patients,after treatment,compare the difference on ovarian function between the two groups.Re-sults In the study group,although these difference,the average number of oocytes,fertilization rate,clinical pregnancy rate and other indicators,were not statistically significant (P>0.05),they were higher than the control group;early abortion rate was no significant difference either (P>0.05),but the tubal pregnancy rate was lower than the control group,and the difference was statis-tically significant (P<0.05).Conclusion Tubal bolt blocking technique is an effective method for hydrosalpinx pretreatment,and partly superior than gynecological surgery for keeping ovarian function and IVF-ET treatment targets.So,it has a broad application prospects in vitro fertilization-embryo transfer.

Objective:To summarize and analyze the clinical characteristics of different treatment in children with esophageal foreign bodies.Methods:This study collected 246 children with esophageal foreign bodies in our hospital from January 2016 to January 2020, which was divided into endoscopic group and operative group.The general and clinical data of children treated with different treatment were collected and statistical analyzed.Results:There were 222 children in endoscopic group and 24 children in operative group, respectively.The rate of surgery was 9.75%.There were no significant differences in gender and location of esophageal foreign bodies.However, the average age of operative group was(2.92±2.67) years, which significantly younger than that in endoscopic group(4.12±3.37)years( P=0.049). The residence time in operative group(median 29.10 h)was remarkable longer than that in operative group(median 11.80 h)( P<0.001). The proportion of sharpness(50.00%) and corrosive(45.83%) foreign bodies in operative group were more than those in endoscopic group[16.22% and 8.11%( P<0.001)]. Moreover, the occurrence rate of major complication in operative group was 83.33%, which was dramatically higher than that in endoscopic group(0.90%)( P<0.001). Conclusion:The younger and longer residence time of esophageal foreign bodies in children contribute to the rate of operative treatment.Additionally, the sharpness and corrosive foreign bodies increase the risk of surgery and serious complications.

Objective To observe the effect of combining virtual reality technology with occupational thera-py in treating children with spastic hemiplegia resulting from cerebral palsy. Methods Thirty-eight spastic and hemiplegic children with cerebral palsy were randomly divided into a treatment group ( n=18) and a control group ( n=20) . Both groups received occupational therapy, while the treatment group was additionally provided with virtual reality-based treatment. The sessions lasted 30 min, 6 times a week for 3 months. Before and after the treatment the upper extremity motor function of both groups was assessed using the fine motor quotients of the Peabody developmen-tal motor scale, the Caroll hand function scale and a activities of daily life scale. Results Before the treatment there was no significant difference between the two groups in terms of any of the measurements. After the 3 months, significant improvement was observed in both groups, but the improvement of the treatment group was significantly greater than that of the control group. Conclusion Virtual reality technology can further improve the motor function of the upper ex-tremities and ability in the activities of daily life beyond that achievable through occupational therapy alone.

Objective To reveal the self-management status of patients with hypertension in community, and to analyze the influencing factors of self-management behavior so as to provide theoretical basis for the formation and maintenance of self-management. Methods With the method of stratified random cluster sampling, 559 patients with hypertension were selected from twelve communities in six urban districts of Wuhan completed the questionnaire survey to analyze the demographic characteristics, executive condition of self-management behavior and related psychological behavior with hypertension patients. Results The average age was (61.2 ± 8.4) years. The rate of measuring blood pressure regularly was 38.39%, rate of regular medication was 63.83%, rate of low salt diet was 37.72%, and the rate of regular exercise was 50.45%. The score of self-management was 0.60 ± 0.21. Self efficacy was the influencing factor of self-management score (β=0.042 1,P<0.01). Conclusion Self assessed efficacy is closely related to self-management. Intervention should be guided by psychological behavior theory, and emphasized on psychological aspect.

Objective To explore the relevance between gait speed and muscle strength of lower extremities, or several kinds of physical functional tests. Methods 341 community-dwelling individuals (160 males, 181 females) aged 65-94 years were selected. They were divided into suspected sarcopenia group (n=137) and normal group (n=204) by their gait speed less or more than 0.8 m/s. It was compared between both groups with the basic physical characteristics, strength of iliopsoas, quadriceps, hamstrings and tibialis anterior, and the scores of One Leg Standing Test, Berg Balance Scale, Functional Gait Assessment, Functional Stretch Test and Timed Up and Go Test. Results The subjects were older in the suspected sarcopenia group than in the normal group. The difference of body weight, height were not statistically significant between groups. The strength of the muscles in bilateral lower limbs was not significantly different between both groups (P>0.05), while the gait speed positively correlated with the strength of iliopsoas, quadriceps and hamstrings (r=0.121-0.227, P<0.05), but not with the tibialis anterior (P>0.05). Gait speed positively correlated with the scores of One Leg Standing Test, Berg Balance Scale, Functional Gait Assessment, Functional Stretch Test (P<0.05), and negatively correlated with the score of Timed Up and Go Test (r=-0.502, P<0.001). The scores of all the tests were significantly different between 2 groups (P<0.05), except that of Functional Stretch Test (P=0.28). Conclusion Sarcopenia diagnosis is not only depended on the strength of muscle of lower extremity, but also their functions.

Clinical data of 12 cases of Trousseau syndrome with cerebral infarction as initial presentation admitted in the neurology department of the Fourth Affiliated Hospital of Hebei Medical University from December 2011 to December 2017 were retrospectively analyzed.Of the 12 patients,4 cases had risk factors for cerebral infarction and 8 ones had no risk factors.There were 2 patients with 1 lesion and 10 patients with two or more lesions in brain imaging.The infarction lesions of 9 patients were located in 2 or more arterial blood supply areas.Ten patients showed an elevated plasma D-dimer level,5 had elevated fibrinogen level,7 showed increased blood platelet count and 8 had increased homocysteine level.Ten cases were confirmed by pathology,2 cases by clinic and imaging diagnosis.The study suggests that multiple lesions with several cerebral arteries involved,high plasma D-dimer and fibrinogen levels may be the clinical characteristics of Trousseau syndrome with initial presentation as acute ischemic stroke and lacking of risk factors.The hypercoagulation state may be the important pathogenesis of this disorder.

OBJECTIVE To illuminate the adenoid bacteria distribution in children with adenoid hypertrophy. METHODS PubMed, Embash, Medline, CNKI, VIP Information and Wanfang data were searched for studies on the adenoid bacteria distribution and adenoid hypertrophy. Random effects meta-analysis was used to pool data. RESULTS Nine studies were included in this meta analysis. The pooled detection rates of haemophilus influenza, staphylococcus aureus and streptococcus pneumonia were 0.21 (95%CI, 0.09-0.32), 0.14 (95%CI, 0.09-0.20) and 0.15 (95%CI , 0.08-0.22) respectively. CONCLUSION Haemophilus influenzae, staphylococcus aureus, and streptococcus pneumoniae are three main kinds of pathogenic bacteria of adenoid hypertrophy in children.
