Improved manipulation of oblique-pulling (Ban) and fixed-position rotating pulling were applied to the patient with the prolapse of lumbar intervebral disc for reduction. Then acupuncture therapy, which used Shuigou (GV 26) and Weizhong (BL 40) as the main acupoints, was used. Totally 97 cases were treated, 58 cases were cured, 35 cases were improved, and 4 cases had no effect. The total effective rate was 95.5%.

Objective To explore the methylation status of hMLH1 and hMSH2 promoter region in the epithelial ovarian cancer and its role in oncogenesis.Methods Methylation status of hMLH1 and hMSH2 promoter region was assayed in 20 normal ovarian tissues,25 benign epithelial tumor,56 malignant epithelial tumor and cell lines SKOV3,3AO by methylation-specific PCR (MSP).SKOV3 and 3AO were analyzed before and after 5-aza-2′-deoxycytidine (5-Aza-CdR) treatment.In addition,an alterations of mRNA expression of hMLH1 and hMSH2 was observed by reverse transcription polymerase chain reaction (PT-PCR).Results No methylation of hMLH1 and hMSH2 promoter was found in normal ovarian tissues. CPG islands methylation of hMLH1 and hMSH2 was observed in 4% (1/25),8% (2/25) respectively in benign epithelial tumor,30.4% (17/56),51.8% (29/56) respectively in malignant epithelial tumor. Methylation status in promoter showed obvious correlation with pathological grade and lymph node metastasis (P

Purpose To investigate the clinicopathologic features of calcifying aponeurotic fibroma (CAF). Methods The clinical and pathologic profiles of 6 cases of CAF were retrospectively analyzed. Results CAF appeared a firm, painless and slowly growing mass with a predilection for the distal portions of the extremities in young children and adolescents. Microscopically, the tumor consis-ted mainly of benign appearing spindle cells, chondroid cells and calcific debris. Immunohistochemically, the tumor cells were positive for vimentin, HHF-35, S-100, Calponin and CD68. Conclusion CAF is a rare, locally aggressive fibroblastic lesion. It can make an accurate diagnosis by integrating the clinical location with histopathological features. Repeated minor trauma to the extremities and some embryologic cell nests maybe its pathogenesis.

Objective To investigate the diagnostic value of thyroglobulin measurement in fine-needle aspiration biopsy(FNA-Tg).Methods This study included 63 patients with thyroid cancer or with enlarged lymph nodes during the follow-up from Aug.2010 to Jun.2012.Ultrasound-guided fine-needle aspiration was done in the 63 patients with 79 suspicious enlarged lymph nodes.Then thyroglobulin(Tg) in FNA washout fluid and serum Tg were assayed with electrochemiluminescenceimmunoassay(ECLIA).Diagnostic sensitivity,specificity and area under the ROC curve were evaluated according to 5 predetermined threshold levels:FNA-Tg/serum-Tg ＞ 1,mean + 2SD of node-negative patients,10 ng/ml,optimal operating point of ROC curve and 1000 ng/ml.Results The sensitivity value was 90.70％,90.70％,95.35％,90.70％ and 65.12％ respectively on the 5 threshold level,significantly lower than those on the threshold level of 1000 ng/ml(P ＜0.05).The specificity value was 97.22％,91.67％,72.22％,97.22％ and 100％ (P ＞0.05) on those threshold levels,significantly lower than those on the threshold level of 10 ng/ml (P ＜0.05).The area under the ROC curve was 0.940,0.912,0.838,0.940 and 0.826 respectively.There was no statistical difference(P ＞0.05).Conclusion Selecting FNA-Tg/serum-Tg ＞ 1 as a positive threshold value can be a secondary diagnosis of lymph nodes metastasis in patients with papillary thyroid cancer.

Objective To discuss the effects and influence of preoperative and postoperative adjunctive intravitreal conbercept in 23G vitrectomy for proliferative diabetic retinopathy (PDR).Methods A retrospective research was performed on 42 PDR eyes from January 2015 to February 2016 in the Second Affiliated Hospital of Nanchang University,who received either intravitreal 0.05 mL conbercept injection 7 days before 23G vitrectomy (group A,n =22) or intravitreal 0.05 mL conbercept injection at the end of 23 G vitrectomy (group B,n =20).The operative time,postoperative vitreous hemorrhage (VH),intraoperative and postoperative other differences of clinical indicators and postoperative best-corrected visual acuity (BCVA) between the two groups were compared.Results The average operation time,intraoperative electric coagulation hemostasis rate,iatrogenic hiatal incidence and intraoperative hemorrhage rate of group A were lower than those of group B (all P ＜ 0.05).BCVA at 6 months after surgery did not differ significantly between two groups (P ＞ 0.05),but the difference was statistically significant between pre-operation and post-operation (P ＜ 0.05).The incidences of early (≤ 1 month) postoperative VH were 18.2％ (4 eyes) and 15.0％ (3 eyes) in group A and B,respectively (P ＞ 0.05).The incidences of later (＞ 1 month) postoperative VH were 27.3％ (6 eyes) and 0 in group A and B,respectively,the difference was statistically significant (P ＜0.05).The percentages of reoperation were 13.6％ (3eyes with postoperative VH) and 10.0％ (2 eyes with traction retinal detachment) respectively in group A and B.The average times of supplementary laser photocoagulation were (2.3 ± 1.0) times and (1.4 ±0.6) times in group A and B,respectively in follow-up period (P ＜ 0.05).Conclusion The adjunctive use of intraoperative intravitreal injection of conbercept can prevent effectively postoperative VH and decrease conveniently the time of supplementary laser photocoagulation in 23G vitrectomy for PDR,as well as the preoperative adjunctive use can decrease the operation time,intraoperative complications and incidences of early postoperative VH.

Activation of the transcription factor NF-E2-related factor 2 (Nrf2)-signaling pathway is an adaptive response to environmental and endogenous stresses and serves to render animals resistant to chemical carcinogenesis and other forms of toxicity. However, overexpression of Nrf2 has been recognized to promote oncogenesis and resistance to chemotherapy. The application of Nrf2 in tumor chemoprevention and treatment has also become a hot topic. This review focuses on the dual roles of Nrf2 in tumorigenesis and the application of Nrf2 in tumor chemoprevention and treatment.
