Objective: By observing the effect of Kanglaite (KLT) Injection in combination with gefitinib on angiogenesis in mice with Lewis lung cancer, to explore its possible mechanism. Methods: Lewis lung cancer model was established in C57BL/6 mice. Forty model mice were randomized into 4 groups: control group, KLT treatment group, gefitinib treatment group, and KLT+gefitinib treatment group. Using immunohistochemistry and RT-PCR technology to observe and compare tumor growth and angiogenesis in each treatment group. Results: The average weight of the tumor in KLT+gefitinib treatment group was lower than those in the KLT treatment group and the gefitinib treatment group; the difference was statistically significant (P < 0.01). Judging from the inhibition rate, KLT, gefitinib, and KLT+gefitinib can inhibit the growth of the transplanted tumor, especially for the combination treatment. The microvessel density (MVD)-positive labeling index (LI) in control group, KLT treatment group, gefitinib treatment group and the KLT+gefitinib treatment group were 24.35±1.06, 18.25±1.36, 20.09±1.46 and 14.46±0.98, respectively. The MVD of the KLT+gefitinib treatment group was lower than those of the two single drug groups; the difference was statistically significant (P < 0.01). The expression levels of VEGF and KDR proteins in the KLT treatment group and the gefitinib treatment group were lower than that of the control group (P <0.05) and higher than that of the KLT+gefitinib group (P < 0.05). The expression levels of VEGF and KDR mRNAs in the KLT+gefitinib group was lower than those of the two single drug groups; the difference was statistically significant (P < 0.05). Conclusion: KLT combined with gefitinib treatment may exert synergistic effect on anti-angiogenesis, so as to obtain synergistic anti-tumor effect. Copyright © 2013 by TUMOR.

Objective The aim of the study is to investigate the prevalence of cognitive impairment and frontotemporal dysfunction in Chinese patients with motor neuron disease(MND).Methods 100 Datients diagnosed as MND underwent a series of survey including mini mental state examination(MMSE),neuropsychiatry inventory(NPI),Hamilton depression scale(HAMD)and Hamilton anxiety scale (HAMA).Demographics,site of onset,and disease severity-functional rating scale(FRS)were also investigated.Results The prevalence of mild cognitive impairment determined with MMSE score was 24.2%.Compal ison between patients with normal and abnormal MMSE showed statistic differences in depression state and FRS score.Since patients with anxiety and depression would also have abnormal NPI,a follow uP stndy after 3-month antidepressive therapy for the depression patients was made and 2 patients were found to haye Drobably frontotemporal dysfunction lasting for more than 6 months.Conclusion MND patients might have mild impairmented of cognitive function and some of the patients were neuroethologically abnormal.2 of the patients might have frontotcmporal dysfunction.

Joint detection could increase the sensitivity up to 88.89％. Conclusion GP73 was a high sensitivity mark for dignosis of PHC, while AFP-L3％ was a high specificity mark for dignosis of PHC. The joint detection could improve PHC diagnostic performance.

Objective To clarify the characteristics of shock wave sources generated at different medium interfaces.Methods The experiment used an in vitro adjustable impact pressure shock wave generation and signal acquisition system combined with a flexible PVDF sensor.The waveform of the shock wave generated by the applicator at the interface of different media(soft tissue-mimicking phantom,water and air)was explored.The characteristics of the shock wave source in the time and frequency domains were analyzed.Results When the same impact pressure was applied,shock waveforms generated at the interfaces of the phantom and water exhibited similar characteristics from a time-domain perspective.At the same time,both differed significantly from those generated at the air interface,where the absolute values of the positive and negative pressures were noticeably reduced.The characteristics of the shockwave spectra in various media revealed three distinct peak frequencies,with the modulation frequencies varying in the phantom(12.2 kHz),water(8.5 kHz),and air(7.2 kHz).In contrast,the carrier frequency remained relatively constant(between 82 and 83 kHz).When different impact pressures were applied,there was little influence on the waveform at the same medium interface,indicating that the impact pressure affected only the shockwave amplitude and not the peak frequency.As the impact pressure increases,the absolute values of the positive and negative pressures at the medium interface increase linearly.Conclusions Shockwave sources can be effectively measured using a flexible PVDF sensor.Shock waves generated at different medium interfaces exhibit temporal and spectral differences,indicating that the characteristics of shock wave propagation in air or water cannot be substituted for those in biological soft tissues.These findings provide crucial information for evaluating shockwave devices and formulating treatment protocols in the clinic.

OBJECTIVETo compare the characteristics of over weight and obesity subjects defined by three criteria: World Health Organization (WHO) in 1999, the National Cholesterol Education Program Adult Treatment Panel Nll (NCEP-ATP II ) in 2001, and the International Diabetes Federation (IDF) in 2005.

METHODSMedical history collection, physical examination, oral glucose tolerance test ( OGTT) , and frequently sampled intravenous glucose tolerance test (FSIGTT) were performed in 371 subjects with body mass index (BMI)> or =23 kg/m(2). Fasting blood samples were taken to test lipid profiles, urea acid level and so on. Data was analyzed including comparison and relationship statistics.

RESULTSData from FSIGTT showed that insulin resistance existed in all over weight and obesity subjects. The relationship between waist and sensitivity index (SI) was superior than that between BMI and SI ( r = - 0. 198 and r = - 0. 194, P < 0. 001). Totally 107 subjects (28. 8%) did not meet any definitions, 187 (50. 4%) met ATP definition, 98 (26. 4%) met WHO definition, and 234 (63. 1% ) met IDF definition. ATP and IDF definitions had the highest coincidence rate (70. 3% ) , and subjects in these two groups almost had basically the same manifestations. The age of onset in WHO group was higher than those in other two groups. Meanwhile, subjects in the WHO group was characterized by lower BMI, higher hyperlipidemia, and significantly increased fasting and postprandial blood glucose level. The MS component scores were positively correlated with age, BMI, waist, and waist-to-hip ratio (WHR) , and were negatively correlated with SI. However, no correlation was found between MS component scores and gender, fat% , or acute insulin response to glucose index.

CONCLUSIONSSome of over weight and obesity subjects only have insulin resistance and have no metabolism syndrome. The group defined by IDF criteria of the metabolic syndrome (MS) has the highest incidence rate. Limited by the requirements of insulin resistance evaluation, the definition proposed by WHO is somewhat unfeasible for practices. ATP definition may be replaced by IDF definition, because the populations defined by ATP definition is covered by the latter. Meanwhile, the abnormalities of fat mass distribution in the body ( i. e. , central obesity) , rather than its contents, may exacerbate the occurrence of MS, as well as the development of insulin resistance.

OBJECTIVE: To investigate the incidence of neonatal asphyxia and possible contributing factors for the development of severe asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture, China. METHODS: A total of 16 hospitals in Hubei Enshi Tujia and Miao Autonomous Prefecture were selected as research centers. A retrospective analysis was performed for the clinical data of 22 294 live births in these 16 hospitals from January to December, 2016 to investigate the incidence rate of neonatal asphyxia and possible contributing factors for the development of severe asphyxia. RESULTS: Of the 22 294 neonates born alive, 733 (3.29%) were diagnosed with neonatal asphyxia, among whom 627 had mild asphyxia and 106 had severe asphyxia. The neonates with low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight had a higher incidence of severe asphyxia (P<0.05). CONCLUSIONS The incidence rate of neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture is higher. Low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight may be related to the development of severe neonatal asphyxia.

OBJECTIVE: To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China. METHODS: According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017. RESULTS: A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66). CONCLUSIONS Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.
