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.

Clinical efficacy scale of traditional Chinese medicine (TCM) should be built according to the characteristics of TCM, scientific demand, and demonstrated by practice. This paper provides some considerations of the scale.

ObjectiveTo evaluate the clinical efficacy of Sedum freckle capsule combined with hydroquinone cream phonophoresis in the treatment of chloasma.MethodsA total of 180 patients with chloasma were recruited into two groups according to the random number table, 100 in the treatment group and 80 in the control group. The patients in the control group were treated with 2% hydroquinone cream phonophoresis, and those in the treatment group received 2% hydroquinone cream phonophoresis and Sedum freckle capsules, both for 2 months. The symptom and lesion score were usedto evaluate the clinical efficacy. ResultsThe cure rates were 81.00% in the treatment group and 67.50% (χ2=4.320,P=0.038) in the control group at the end of treatment, 92.0% and 76.3% (χ2=5.538,P=0.019) at 2 months follow-up. The total lesion scores at the end of treatment and at 2 months follow-up were significantly lower than before the treatment in the treatment group (1.61 ± 0.84 and 1.30 ± 0.85vs.3.48 ± 1.02;t=14.152, 16.419, allP<0.01) and also in the control group (2.04 ± 0.61 and 2.03 ± 0.51vs.3.45 ± 1.09;t=10.097, 10.554, allP<0.01). The total lesion score at the end of treatment and at 2 months follow-up were significantly lower than in the treatment group was significantly decreased than the control group (t=3.839, 6.767; allP<0.01).ConclusionSedum freckle capsule combined with hydroquinone cream phonophoresis could effectively treat patients with chloasma.

This paper reports the results of surgical management of 38 patients with chronic gasric and duodenal ulcer complicted with mycotic infection.This disease was easily be misdiagnosed as gas- tric carcinoma,especially when a mass can be palpated in the upperabdomen.Gastroscopical biopsy was the most effective method of diagnosis.When the ulcer complicated with mild mycotic infection,it can be treated by anti-mycotic drugs.But if the ulcer is large and deep,or complicated with hemorrhage,perforation or malignancy,the treatment of choice is surgery.Before operation,using anti-mycotic drugs to prevent the occurrence of mycotic sepsis must be consider- ated.During operation,if malignancy is suspected,frozen section should be taken.

The content of fibronectin in skin incised wound of adult abdomen was rneasured with double antibody sandwich EI,lSA is report.The result indicated that it is possible to measure fibronectin in extracts of skin tissue. The mean extractable fibronectin level per gram adult abdominal skin was 7. 5920?1. 7364ug (M ? SD ). The content of fibronectin in incised wound at different groups in lccal area intervals after injury increased gradually,acconlpy1ng along with the tirne prolonged. There existed a linear correlation between the tlme elapsed after 1n jury and the fibronectin content in wounds. But,only O. 5hr or longer than 0. 5hr after injury the difference between local skin fibronectin and instantenous one is significant (P

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.
