Primitive neuroectodermal tumor (PNET) is a kind of malignant tumor, which most often affects children and adolescents. The incidence of PNET has risen recently. PNET has low early diagnosis rate and poor treatment effect. With the application of RT-PCR and FISH in pathological diagnosis, and MRI and PET-CT in imageological diagnosis, as well as the implementation of target treatment and multidisciplinary integrated treatment concept in the treatment, the pathogenesis, diagnosis technology and treatment means of of PNET have made remarkable progress.

The Viet Duc Hospital found 6 cases of the postoperative left gauze by ultrasound during 1997-1998. The diagnosis based on the clinical symptoms (infectious sign), operative history, position and size of foreign body. The foreign bodies found earliest in the 20th days and longest in the 4th years after an operation. The form, size and structure of the foreign bodies have not been changed through the round of examination.

Objective To establish a HPLC method for determining of the content of palmatine hydrochloride in Fuke Qianjin Tablets. Methods HPLC was performed on Shimadzu-C18 column. The mobile phase consisted of 0.05 mol·L-1 sodium acid phosphate (pH=3, adjusted by phosphoric acid)-acetonitrile (72 : 28). The detection wavelength was at 265 nm. Results The linear correlation was in the range of 0. 051 μg～0. 255 μg(r=0. 999 9). The average recovery was 100. 04 %, and RSD=1.03 % (n=5). Conclusion The method is accurate and specific.

[Objective]Acute lumbar sprain is a common disease in clinical acupuncture treatment, inconvenient in patients with daily life, this paper system-atical y analyses a single point in treatment of acute lumbar sprain. [Method] The research through the literature and some clinical physician experience, and the treating principle analysis. [Results] Summarized the clinical on commonly used and effective acupuncture point, proving its real y good effect on acute lumbar sprain. [Conclusion] The treatment of acute lumbar sprain with single point method is simple, fast and effective.

Advanced colorectal cancer mainly classified as locally advanced,locally recurrent and distally metastatic colorectal cancer.Distal metastasis of colorectal cancer includes peritoneal metastasis,liver,lung and other organ metastasis.Surgical resection remains the only possible cure for patients with advanced colorectal cancer.Preoperative systemic evaluation based on radiographic images,especially the evaluation on the resectability of hepatic metastatic lesions from colorectal cancer is very important.Neo-adjuvant and adjuvant therapy increased the resection rate of primary and metastatic lesions of advanced colorectal cancer.In recent 10 years,with the development of oncolegical surgery,treatment modality of multi-disciplinary team has been proposed and implemented,which increased the survival time and improved the life quality of patients with colorectal cancer.

Small bowel intusssusception is relatively rare in children and the manifestation is always atypical.Abdominal ultra-sonography conduces to final diagnosis.It can be classified into transient and persistent small bowel intussusception with their own clinical characteristics respectively.This article systematically reviews the clinical features and treatment advances of small bowel intussusception in children.

Objective To study expression clinical significance of serum guanine nucleotide dissociation inhibitor 2 (RhoGDI2), natural killer ccll activation receptor 2D (NKG2D) in patients with advanced lung cancer.Methods From January 2012 to December 2014,50 cases of middle-late stage lung cancer patients as the research object,20 patients with lung adenocarcinoma, 18 cases of adenocarcinoma of lung, 12 cases with small cell lung cancer;30 cases of phase Ⅲ, 20 cases of Ⅳ;22 cases of lymph node metastasis, 28 cases without lymph node metastasis.From January 2012 to December 2014,50 healthy subjects as control group.Flow cytometry instrument was used to detect NKG2D, and ELISA method was used to detect RhoGDI2.Results The RhoGDI2 level of lung cancer patients in Ⅳ, Ⅲ stage higher than the control group ((70.19±8.54), (49.76 ±7.25) vs (5.62± 1.26) μg/L)), the NKG2D level lower than the control group ((71.49± 5.57)％, (78.97 ±6.62)％ vs (84.59±6.96)％ ,P＜0.05).The RhoGDI2 level of lung cancer patients with stage Ⅳ was higher than that of patients with stage Ⅲ((70.19±8.54) μg/L vs (49.76±7.25) μg/L) ,while the NKG2D level of lung cancer patients with stage Ⅳ was lower than that of patients with stage Ⅲ((71.49±5.57) ％ vs (78.97 ±6.62) ％, P＜0.05).RhoGDI2 level of patients with lymph node metastasis was higher than that of patients with no lymph node metastasis((71.32±6.79) μg/L vs (48.29±2.36) μg/L,P＜0.01) ,NKG2D level of lymph node metastasis was lower than without lymph node metastasis in patients ((72.36 ± 6.62)％与 (81.27 ±6.86)％, P ＜0.01).There was negative correlation between serum RhoGDI2, NKG2D expression (r =-4.176, P =0.011).Conclusion There are relationship between the abnormal expression of RhoGDI2 and NKG2D with the clinical stages,lymph node metastasis of the tumor of lung cancer, and has nothing to do with the type of lung cancer.There is negative correlation between the expression of RhoGDI2 and NKG2D.
