International Journal of Traditional Chinese Medicine 2015;37(10):879-882
Objective To observe the clinical treatment effects of Qingkailing injection on Alzheimer's disease.Methods 84 patients with AD were randomly divided into a control group and a treatment group (n=42 cases,per group). The patients in both groups orally took 5 mg of donepezil hydrochloride every night. The Qingkailing injection of 60 ml was administrated by intravenous drip in addition to oral uptake of donepezil hydrochloride to the treatment group. The total treatment period of both groups was 20 weeks. The MMSE, ADL score, HS-CRP, IL-6, MDA and ox-LDL content and the clinical treatment results and differences in the two groups before and after the treatment were observed.Results After treatment, the serum HS-CRP (4.18 ± 0.38 mg/Lvs. 5.78 ± 0.53 mg/L,t=15.900), IL-6 (34.28 ± 4.33?g/L vs.44.75 ± 4.99?g/L,t=10.270), MDA (6.04 ± 0.98?mol/L vs.7.43 ± 0.69?mol/L,t=7.516), ox-LDL (62.87 ± 7.65?g/L vs.102.56 ± 9.81?g/L, t=26.677) content of the treatment group were significantly decreased than the control group (P<0.01). The total effective rate between the treatment group and the control group had significance difference (83.3%vs. 61.9%;χ2=4.850,P=0.028). The MMSE score in both groups after the treatment were higher than those in the same group(t value were 8.036, 7.475, respectively,P<0.01), ADL scores in both groups after treatment were lower than those before treatment(t value were 7.818, 5.960, respectively,P<0.01), but no significance difference between the two groups(t value were 1.633, 1.710,respectively,P value were 0.106, 0.091, respectively).Conclusion The treatment effect of Qingkailing injection on Alzheimer's disease was sound.

Chinese Journal of Rehabilitation Theory and Practice 2008;14(3):296-297
One of the hallmark features of children with autism is language barrier,which mainly manifested with lack of visual contact and attention,imitation speech,broad pronunciation problems,poor understanding abilities to speech and abstract questions,deficiency of logicality,spoken language disorder,confusion about the usage of pronouns such as you,I and she or he,etc.According to the basic principles of language training,visual perception tracing,vision contact,cultivation of communication desire,auditory and understanding training can all be used to make children with autism to understand the relationship between pronunciation and words,try to pronounce syllables,make good preparation for valid pronunciation in the early stage of language training.Respiration training,point massage of oral surface and valid usage of pronunciation organs' practice can help them to say phrase and simple sentences gradually.They can say a sentence correctly and achieve the destination of grasping language through learning decorative words and enhancement of understanding and logic abilities.Very efficient result could be approached through correct evaluation,found existing problems and using correct training methods during language training of children with autism.

Objective To observe the protective effect of alcholic extractive of Cornu Cervi against the myocardial damage of acute myocardial infarction model rats. Methods The myocardial ischemia rats model was made by ligaturing their coronary attery, and the indexes including electrocardiogram, the area of acute myocardial infarction and ET of acute myocardial infarction model rats were observed after the acute period of myocardial damage. Results The alcoholic extractive of Cornu Cervi could obviously improve the degree of myocardial ischemia, reduce the area of myocardial ischemia, and lessen the level of ET. Conclusion The alcoholic extractive of Cornu Cervi could protect the myocardial against the damage of acute myocardial infarction model rats in some degree. The mechanism may be related to the reduction of value of ET of myocardial damage.

Objection To study the effect of letrozole on EM rat models and influence on the reproductive system. Methods Surgically transplanted autologous uterine tissues to ectopic site beside the uterines in rats were used as animal models to study endometriosis. 20 EM model rats were random divided into letrozole-treated group and saline solution-treated control group. The change of ectopic lesion volume in each group was compared before and after treatment. Apoptotic cells were assessed by the terminal deoxynucleotidyl transferase-mediated deoxy-UTP nick-end labeling (TUNEL) assay, and the uterian horn and ovary were weighted and observed by optical microscopy to study the change of morphology. Results The volumes of the endometriotic tissues of letrozole group reduced more than that in control group[ ( 28. 75 ± 2.28 )mm3 vs ( 108.39 ±9. 98)mm3, P <0.01 ]. The apoptotic rate in letrozole group [ (5.52 ±2. 81 )% ]was higher than control group[ (2.11 ± 1.70)%, P <0. 01 ]. The ovarian weights in letrozole-treated group increased significantly[ (25.25 ± 9. 89) mg/100g vs ( 13. 10 ± 2. 70 ) mg/100g, P < 0. 01 ], arid the ovaries showed polycyst. The uterian weights in letrozole-treated group[ (41.46 ± 15.81 ) mg/100g vs (94. 81 ±18.00) mg/100g, P <0. 05 ] significantly decreased, and the endometriums presented atrophy. Conclusion Letrozole treated EM by means of increasing the apoptosis of the ectopic tissues. Letrozole would give ovarian over stimulating and the uterian weighting decreased as well as endometriums atrophy.

Objective To investigate the expression of TLR2 and HIF-1α in pancreatic cancer and explore the relationship between TLR2 or HIF-1α protein and the clinical or pathological changes in pancreatic cancer. Methods The mRNA of TLR2 and HIF-1α in 30 cases of pancreatic cancer and its adjacent tissues were detected with real-time PCR and with immunohistochemical methods in 65 cases of pancreatic cancer and 38 cases of corresponding adjacent tissues. The relationship between TLR2 or HIF-1α and pathologic features of pancreatic cancer was analyzed. The correlation between TLR2 and HIF-1α in pancreatic cancer was also assessed. Kaplan-Meier method was used to assess the impact of TLR2 or HIF1αexpression on survival. Results The relative quantification of TLR2 mRNA and HIF-1α mRNA in pancreatic cancer tissues was 0.84±0.17 and 0.87±0.11, respectively, which was significantly higher than that in adjacent tissues 0.70±0.13 and 0.68±0.13 respectively,P<0.05. The protein expression of TLR2 and HIF-1α in pancreatic cancer tissues was 63. 10% and 70.8%, respectively, significantly higher than that in adjacent tissues (34.20% and 36.8%, respectively). There was no significant correlation between the expression of TLR2 or HIF-1α protein and the age, gender, tumor location, the degree of differentiation in patients with pancreatic cancer (P>0.05). However, there was significant correlation between the expression of TLR2 or HIF-1α protein and tumor size, lymph node metastasis, venous invasion and clinical staging. TLR2 and HIF-1α had a significant impact on survival. Conclusion TLR2 and HIF-1α overexpressed in pancreatic cancer and TLR2 signaling pathway may promote development of the pancreatic cancer with HIF-1α together.
