Objective To study the clinical characteristics and treatment of functional articulation disorders. Methods 65 children withfunctional articulation disorders were reported. Results The main erroneous articulation pattern in these children was substitution, followedby omission and/or distortion. They were trained from oral function and articulation motion for 2~6 months. 58 children were corrected completely,and 7 were corrected partially. Conclusion The main erroneous articulation pattern of functional articulation disorder in children issubstitution. Speech training is effective on it.

Objective To investigate the importance of PTEN protein and CD44v6 detection to the prediction of laryngeal carcinoma differentiation and cervical lymph node metastasis. Methods The expressions of PTEN protein and CD44v6 were detected by immunohistochemical SP method in 97 specimens with laryngeal carcinoma and 97 specimens with a distance over 2.5 centimeters from laryngeal carcinoma. The relations between them and their clinical significance to the laryngeal squamous cell carcinoma above Glottis by the statistical analyses tools were revealed. Results The positive expression rates of PTEN protein were respectively 55.67 %, 100 % in laryngeal carcinoma and adjacent carcinoma tissue. There was a significant difference between them statistically (P<0.01). The positive expression rates of PTEN protein are notable difference among the high, middle and low differentiation of laryngeal carcinoma, but not between the positive metastasis of lymph node of neck and the negative one(P >0.05). For the expression of CD44v6, there were notable statistical difference not only among the different differentiation of laryngeal careinoma, but also between the positive metastasis of lymph node of neck and the negative one. The low expressions of PTEN protein and the high expression of CD44v6 in the same carcinoma cell has significant negative correlation (P< 0.05). Conclusion PTEN protein may have the importance to the differentiation of laryngeal carcinoma, but no means to cervical lymph node metastasis. CD44v6 may have great importance to both.

Objective Tetralogy of Fallo( TOF) is one of cyanotic congenital heart disease, which is difficultly diagonosed because of its complicated texture.The aim of this study was to evaluate the manifestation and value of echocardiography in diagnosis of TOF. Methods The fetal sonograms of 99 fetuses with prenatal diagnosis of TOF in 5791 gravida were reviewed and analyzed from January 2010 to December 2012. Results Ninty nine fetuses with TOF were all diagnosed accurately by prenatal ultrasonography, including 11 cases with pulmonary atresia, 2 cases with complete atrio-ventricular septal defect and 4 cases with permanent left superior vena cava.The key echocardiographic features of TOF were ventricular septal defect, overriding aorta and pulmonary stenosis.TOF was accurately diagnosed by prenatal echoeardiography combined with visualization of TOF in four chamber view, outflow tract view and three vessels view.Sixty eight fetuses were confirmed to be TOF by autopsy or operation after birth, 12 cases refused to autopsy and 19 cases lost of follow up in the total 99 cases.None of TOF was reported to us in other 5692 gravidas. Conclusion The echocardio-graphy has important clinic value in diagnosis of fetal TOF with high sensitivity and specificity.

Objective To investigate the effect of different concentrations of arsenic trioxide (As2O3,ATO) on neurokinin A (NKA) in renal tissue of BXSB mice and explore its clinical value.Methods Fifty BXSB mice (twelve weeks old and weighted 23～26 g) were randomly divided into control group,systemic lupus erythematosus (SLE) group,and therapeutic group of three different concentrations of ATO.All biochemical indicators were analyzed before and after treatment.The pathology of renal tissue was examined by immunohistochemistry.The concentration of NKA in renal tissues was detected by ELISA and the concentration of NKA mRNA was detected by RT-PCR.Results The concentration of NKA in SLE group in renal tissue (299±26) pg/g was significantly higher than that of normal control group (122±7) pg/g (P＜0.05).The concentration of NKA in the SLE group in renal tissue was significantly higher than that of three different concentrations of ATO in low-dose group (151±14) pg/g,moderate--dose group (147±9) pg/g and in highdose group (155±14) pg/g (P＜0.05).No difference was found between three different dosages of ATO treatment groups and normal control groups (P＞0.05).There were no significant differences among three different dosages of ATO treatment group (P＞0.05).The side effects in low-dose group were significantly lower than those of moderate and high-dosage groups (P＜0.05).Conclustion NKA concentration expressed in the renal tissues in the SLE group is higher than that in the control group.Decreasing the concentrations of NKA mRNA in renal tissues may be one of the important mechanisms of ATO in treating SLE.Low-dosage ATO is safe and effective to treat SLE and has therapeutic potentials.

Objective To analyze electrophysiology of peripheral nerve in uremic patients. Methods 24 uremic patients and 19 normalvolunteers were included, surface electrodes were used to observe the electrophysiology performance, including tibial nerve, peroneal nerve,sural nerve and skin sympathetic response. Results The motor conduction, sensory conduction and skin sympathetic response were significantlydifferent between uremia patients and normal volunteers (P<0.05). The electrophysiology performance showed that F wave latencyprolonged, nerve conduction slowed, distal latencies prolonged, sensory fibers damaged more serious than motor fibers. Conclusion Peripheralneuropathy is one of the most common complications in uremia patients, neural electrophysiological abnormalities are significantly earlierthan clinical symptoms, nerve electrophysiological examination is of great significance in diagnosis and evaluation uremic peripheralneuropathy.

AIM: To establish the quality standard for Yushangling Capsule(Angelica Sinensis,Borneolum Syntheticum,Radix et Rhizoma Notoginseng,etc.). METHODS: Angelica Sinensis and Borneolum Syntheticum were identified by TLC,and the contents of effective components were determined by HPLC. RESULTS: Angelica sinensis,and Borneolum Syntheticum could be identified by TLC.The linear ranges of notoginsenoside R_1,ginsenoside Rg_1 and Rb_1 were 0.104 6-1.987 4 ?g,0.407 6-7.744 4 ?g,0.414 8-7.881 2 ?g,respectively,the average recoveries were 99.7%(RSD=0.6%),99.5%(RSD=0.5%),100.1%(RSD=0.7%),respectively CONCLUSION: The method is simple,accurate and high specificity with good repeatability and can be used for quality control of Yushangling Capsule.

Conclusion This method is simple,accurate,specific and reproducible,and can be used for quality control of Fushenning Tablets.

Objective To investigate the significance of the expression levels of humans telomerase reverse transcriptase(hTERT) gene in peripheral blood mononuclear cells with lung cancer patients. Methods From Mar.2002 to Feb.2005,the expression levels of hTERT were detected in 30 lung cancer patients and 15 normal humans by quantitative measurement with RT-PCR. Results The expression levels of hTERT mRNA in lung cancer patients (0.906?0.112) were significant as compared with those health controls(0.407?0.104). Conclusion It is effective to diagnose lung cancer by the quantitative measurement with RT-PCR for the expression levels of hTERT mRNA.
