AIM: To analyze the effect factors of trabeculectomy combined with intraoperative application of mitomycin C in the treatment of neovascular glaucoma.
METHODS: Fifty patients (50 eyes) with neovascular glaucoma collected from January 2013 to August 2015 in our hospital were treated by trabeculectomy combined with intraoperative application of mitomycin C. Single factor and multi factor variables analysis were used for effect factors of trabeculectomy combined with intraoperative application of mitomycin C in the treatment of neovascular glaucoma.
RESULTS: By results of single factor variable analysis,< 50 years old, preoperative intraocular pressure ( IOP) was ≥45mmHg and postoperative occurrence of anterior chamber hemorrhage were risk factors for treatment failure ( P < 0. 05 ), and gender, proliferative diabetic retinopathy and previous cataract surgery and prior photocoagulation were not the risk factors for failure (P>0. 05 ). By multivariate analysis, < 50 years old and postoperative occurrence of anterior chamber hemorrhage were risk factors for treatment failure ( P < 0. 05 ), and preoperative IOP≥45mmHg was not a risk factor (P>0.05). CONCLUSION: For patients < 50 years old with neovascular glaucoma, should be careful on the selection of surgical treatment. For high- risk patients, we should strengthen the monitoring and give timely intervention, which are helpful to improve the prognosis.

OBJECTIVETo summarize application of rafting K-wires technique for tibial plateau fractures.
METHODSFrom January 2013 to January 2015,45 patients with tibial plateau fractures were treated by locking plate with rafting K-wires, including 33 males and 12 females with an average of 44.2 years old ranging from 22 to 56 years old. According to Schatzker classification, 6 cases were type II, 8 were type Ill, 4 were type IV, 4 were type V, and 5 were type VI. Allogeneic bone graft were performed for bone defects. All patients were fixed with two to five K-wires. Part of weight loading were encouraged at 3 months after operation,and full weight-loading were done at 5 months after operation. Postoperative complications were observed,and Rasmussen clinical and radiological assessment were used to evaluate clinical results.
RESULTSAll Patients were followed up from 10 to 23 months with average of 14 months. According to Rasmussen clinical and radiological assessment, clinical scores 23.58 ± 6.33, radiological scores were 14.00 ± 6.33; and excellent and good rates were 82.2% and 77.8% respectively. Four patients occurred severe osteoporosis and collapse of articular surface; 5 patients occurred traumatic arthritis.
CONCLUSIONRafting K-wires technique with anatomized armor plate could effective fix and support platform collapse and joint bone fragments, increase support surface area and reduce postoperative reduction loss rate.

The present is aimed at identifying the activation of TRAFs in n asopharyngeal carcinoma (NPC) in vitro. The differential expression of TRAF2\,TRAF3 was not detected in RN A and protein level, whereas the expression of TRAF1 in HNE2-LMP1 cell lines wa s much more abundant than that in HNE2 cell lines, suggesting that TRAF1 may be an inducible molecule; More importantly, TRAF1, TRAF2 or TRAF3 were activated in the HNE2-LMP1 cells, whereas TRAF1, TRAF2 or TRAF3 were not activated in HNE2 cells as detected by the immunoprecipitation-Western blotting assay. These data provide an experimental basis for our study beginning from the signal transduca tion pathway for the eluccidation of the mechanism of LMP1 carcinogenesis in NP C.

OBJECTIVETo observe the effect of Bushen Wenyang Huayu Recipe (BWHR) on hypoxia inducible factor-1α (HIF-1α), proline hydroxylase2 (PHD2), von Hippel Lindau disease (VHL) suppressor gene expressions in endometriosis (EM) rats with Shen yang deficiency blood stasis syndrome (SYDBSS), and to explore the pathogenesis of EM and the mechanism of BWHR for treating EM.
METHODSTotally 50 SD rats were randomly divided into five groups, i.e., the blank control group, the sham-operation group, the model group, the Chinese medicine (CM) group, and the Western medicine (WM) group, 10 in each group. Rats in the blank control group and the sham-operation group were fed routinely. Rats in the rest 3 groups received 30-day "extended refrigerator freezing and ice water immersion" and combined with " autotransplantation" to establish EM rat model with SYDBSS. One Milliliter BWHR at 3.33 g/mL was administered to rats in the CM group by gastrogavage. Gestrinone at the daily dose of 0. 5 mg/kg was administered to rats in the WM group by gastrogavage. Equal volume of normal saline was administered to rats in the model group, the blank control group, and the sham-operation group. The size and morphology of ectopic foci in rats were observed after 4 weeks of medication. Expressions of serum CA125, plasma cyclic adenosine monophosphate (cAMP), and plasma cyclic guanosine monophosphate (cGMP) were detected by radioimmunoassay. Morphological changes of eutopic endometrium and ectopic tissue were observed under the optical microscope by HE staining. Protein expressions and contents of HIF-lα, PHD2, and VHL were detected by immunohistochemical SABC method and Western blot. mRNA expressions of HIF-1α, PHD2, and VHL were detected by RT-PCR.
RESULTSThe ectopic foci grew significantly in the model group. Their volumes were obviously contracted after treated by CM and WM. Compared with the blank control group and the sham-operation group, serum CA125 and plasma cGMP obviously increased, cAMP obviously decreased (P < 0.05); expressions and contents of HIF-1α mRNA and protein all decreased (P < 0.05); mRNA and protein expressions and contents of PHD2 and VHL all decreased in the model group (P < 0.05). Compared with model group, levels of CA125 and cGMP obviously decreased; cAMP levels obviously increased, expressions and contents of HIF-1α mRNA and protein all increased, mRNA and protein expressions and contents of PHD2 and VHL all increased in the WM group and the CM group (P < 0.05). Compared with the CM group, PHD2 protein contents were higher in the WM group (P < 0.05). HIF-1α was negatively correlated with PHD2 (r = -0.799, P = 0.00). HIF-1α was negatively correlated with VHL (r = -0. 625, P = 0.003).
CONCLUSIONSBWHR could effectively treat EM. Its mechanism might be associated with reducing contents of HIF-1α, serum CA125, and plasma cGMP, and up-regulating expressions of PHD2, VHL, and cAMP.

Objective To explore the clinical and biological characteristics and treatment effect of acute myeloid leukemia (AML) in elderly patients. Methods The clinical data of 62 patients over 60 years old with AML were retrospectively analyzed, and they were compared with those of 60 younger adult patients (18-59 years old) at the same period. Results In elderly patients, the complete remission (CR) rate was 27. 7% and the overall effective rate was 44.7%, which were lower than those of younger adult patients (74.1% and 87.9 %, 1-espectively, P<0.01). The early death rate was 19.0% and the mortality rate during the first two induction chemotherapy was 29. 3% in the elderly, which were higher than those of younger adult patients (3. 3% and 6.7%, 1-espectively,P<0.01). The 27.4% of elderly patients were diagnosed as myelodysplastic syndrome (MDS)-transformed AML, which were more than that of younger adult patients (10.0%, P<0.05), and they had lower CR rate than those without MDS (P<0. 05). The 28.2% of elderly patients had lymphoid antigen positive AML and 71.8% of patients showed CD34+ which were higher than those of younger adult patients (8. 1% and 48.6%, respectively, P<0. 05), and they had lower CR rate than those of lymphoid antigen negative and those of CD34- AML (P<0. 05). Elderly patients had less favorable and more unfavorable karyotypes than younger adult patients (45.7 % and 15.4 %, P<0. 05). Conclusions The elderly patients with AML have more unfavorable prognostic factors than younger adult patients. They have lower CR rate and higher mortality rate. There are many specialties in elderly patients and the treatment strategy should be made more individually.
