Objective To investigate the value of vessel size index(VSI) in grading oligodendroglioma by vessel size imaging technique. Methods Twenty-four histologically confirmed oligodendroglioma cases were enrolled (13 gradeⅡand 11 gradeⅢ) . All patients underwent conventional MRI scanning, followed by multi gradient-echo spin-echo sequence from dynamic susceptibility contrast perfusion to generate VSI maps. Region of interests were contoured on VSI color maps to obtain hot-spot value of mean VSI of microvasculature (VSImean) and maximum VSI of microvasculature (VSImax). Paraffin sections of each case was stained with CD34 to acquire microvascular caliber (VShis). Pearson correlation analysis was used to evaluate the correlation between VSImean, VSImax and VShis respectively. Mann-Whitney U test was used to compare VSImean, VSImax and VShis between grade Ⅱ and Ⅲ oligodendrogliomas. ROC analysis was performed to assess the effectiveness of VSImean, VSImax and VShis in grading oligodendrogliomas. Results Both VSImean and VSImax were strongly correlated with VShis (r=0.738, 0.705,P<0.05). For gradeⅡand Ⅲ oligodendrogliomas, VSImean were 38.93(17.96 to 81.18)μm and 91.49(36.94 to 144.68)μm, VSImax were 45.12(22.30 to 89.65)μm and 121.19(57.29 to 164.00)μm, VShis were 8.51(5.25 to 12.76)μm and 11.03(7.59 to 21.96)μm respectively. VSImean, VSImax, and VShis showed significant difference (Z=-3.505,-3.911, -2.729,P<0.05) between grade Ⅱ and Ⅲ oligodendrogliomas. ROC analysis revealed that the optimal cutoff value, sensitivity, specificity and AUC of VSImean was 52.58 μm, 90.91%, 92.31%, 0.923 respectively, 81.18μm, 90.91%, 100.00%, 0.972 for VSImax, and 9.01μm, 90.00%, 84.62%, 0.838 for VShis respectively. Conclusions Vessel size imaging derived VSI correlated well with histopathology. It could provide valuable information in the pre-operative grading of oligodendroglioma.

Objective To evaluate the histologic changes in the dermis and the changes of the rate of type Ⅲ and type Ⅰ collagen by the radiofrequency device. Methods The effects of radiofrequency current on the dermis were observed. Ten rabbits were treated by radiofrequency, and the histologic change in the dermis were observed by H-E staining and Sirius red staining. Results After RF treatment, the fibers in the dermis appeared more compact and the quantity of the type Ⅲ (red) and type Ⅰ (green) collagen were both increased. The fibers in the dermis appeared more compact and the rate of type Ⅲ and type Ⅰ collagen was increased. It was also found that a significant proliferation of dermal collagen was observed in 8 days after treatment. As time went by, the proliferation of dermal collagen was more pronounced, and the rate of type Ⅲ was increased. Conclusion The radiofrequency current can increase the quantity of collagen in the dermis and increase the rate of type Ⅲ and type Ⅰ collagen, which may be one of the key mechanisms of facial rejuvenation by RF.

OBJECTIVE: To study the methods and efficacy of comprehensive treatment on retractory chronic rhinosinusitis(CRS). METHOD: Thirty-two cases of patients with refractory rhinosinusitis took part in individualized comprehensive treatment program, that is, a healthy diet and moderate exercise, psychological counseling, and reasonable operation and gauze changing, and rational use of drug therapy. RESULT: All patients were followed up for 6 months or more, 26 cases (81.3%) were completely controlled of the disease, 6 cases (18.7%) were partially controlled; the total effective rate was 100%. CONCLUSION In the current situation that CRS etiology and pathogenesis studies have not yet made a breakthrough, and we have not developed a new and effective drug, comprehensive treatment focusing on internal and external factors of refractory rhinosinusitis at the same time, that is, to take a rational healthy diet, moderate exercise, psychological counseling, and reasonable operation and gauze changing, and rational use of drug therapy ect. can obtain better effect.

Objective:To explore the expression level of IL-17,IL-23 in patients with allergic rhinitis (AR) and their clinical significance.Methods:A total of 25 patients with AR were treated as observe group , and 23 healthy volunteers were chosen as the control group.The levels of serum IL-17,IL-23 and specific-IgE ( s-IgE) were compared between the two groups.The relationships among serum IL-17,IL-23 and sIgE in patients with AR were discussed.Results:The levels of IL-17,IL-23 and sIgE in observe group were significantly higher than in control group.There was a positive linear correlation between the IL-17 and IL-23/the IL-23 and sIgE/the sIgE and IL-17 in observe group.Conclusion: The IL-17 , IL-23 might be the two important cytokine in the occurrence and development process of allergic rhinitis.The IL-17,IL-23 might be related to the formation of sIgE.

Aim To investigate the effect of Trillium tschonoskii Maxim ( TTM ) ethanol extract on hypoxia ischemia brain damage ( HIBD ) in neonatal rats and potential mechanisms. Methods Fifty healthy SD rats of 7 day-old were randomly divided into three groups:the sham operation group ( n=10 ) , the model group ( n=20 ) and TTM treatment group ( n=20 ) , which received 3-day intraperitoneal injection of normal saline or ethanol extract of TTM respectively. TTC staining and Nissl staining were performed to detect the cerebral ischemia area and neuronal death. Western blot was used to detect the expression of Bcl-2 and Bax. Re-sults The brain tissue of model group was slightly swollen, and white necrotic zone induced by ischemia occured on the right side of the brain, while the brain morphology of TTM treatment group was good. After TTC staining, ischemia zone was clearly seen on the right side of the brain in model group, while after TTM treatment, the size of ischemic zone was decreased. Compared with the model group , Nissl staining showed the neuronal cells increased in TTM treatment group. Western blot showed the expression of Bcl-2 protein in TTM group increased than that in HIBD model group ( P <0. 01 ) , while the expression of Bax protein de-creased ( P <0. 01 ) . Conclusion TTM therapy is beneficial for HIBD,which may be related to reducing neuronal apoptosis.

INTRODUCTIONPathologically adherent placentas occur when there is a defect of the decidua basalis, typically arising from previous caesarean section, resulting in abnormally invasive implantation of the placenta. The depth of placental invasion varies from the superficial (accreta), to transmural and possibly beyond (percreta).

CLINICAL PICTUREWe report on 2 cases, one treated "conservatively", the other with a caesarean hysterectomy, both of which led to a safe outcome for both mother and baby.

CONCLUSIONSManagement relies on accurate early diagnosis with appropriate perioperative multidisciplinary planning to anticipate and avoid massive obstetric haemorrhage at delivery.

OBJECTIVETo study the use about balloon dilatation before incision for the patients with ureteric stricture.

METHODSSixteen patients with ureteric stricture were included in our study. The cases were reviewed retrospectively with regards to the etiological factor, the site of stricture, symptom and diagnosis. Six patients with ureteric stricture were dilated with balloon before incision using Ho YAG laser. Ten patients with ureteric stricture were dilated with rigid ureteroscope before incision using Ho YAG laser. The double "J" stent was kept for 4-6 weeks after operation. All the patients were followed up by ultrasound, BUN and creatinine. Complete success is defined as symptomatic improvement, resolution of hydronephrosis and absence of ureteric stricture 3 months after removal of the double "J" stent. If the hydronephrosis and ureteric stricture did not deteriorate, and symptom improved after stent removal, it was considered as improvement. Failure is defined as deterioration of hydronephrosis and symptoms upon removal of double "J" stent.

RESULTSThe length of stenosis was from 0.8 to 1.4 cm. Three patients failed to improve after initial dilatation with rigid ureteroscope, but were later successfully dilated using balloon. All the patients who were treated using balloon dilatation were successful. The operative time of balloon dilatation was shorter than that of dilatation by rigid ureteroscope (P < 0.05). However, the cost of balloon dilatation was higher (P < 0.05). The period of follow-up was 3-28 months. None of the patients had any complications. There were 2 cases of recurrent stricture in patients who underwent ureteroscopic dilatation.

CONCLUSIONSDespite a higher cost, balloon dilatation followed by laser incision for ureteric stricture is safe and effective. This technique may be used for selected patients.
