ObjectiveTo investigate the pattern of the relationship of craniopharyngiomas with pituitary stalks and hypothalamus. Furthermore, based on different patterns affirmed during the operations, surgical strategies were designed for radical excision. MethodsA series of 66 patients with primary suprasellar craniopharyngiomas were treated with microsurgical techniques and the relationships of the craniopharyngiomas with pituitary stalk and hypothalamus were analyzed prospectively. Appropriate surgical approaches were selected preoperatively according to the lesion's sizes and expanding directions. The relationships of the lesions to the pituitary stalks and hypothalamus were identified in detail and dissected carefully with protection of perforating vessels. ResultsThe patterns that pituitary stalks were involved by craniopharyngiomas were identified in 36 cases and divided into four types: no relation (5 cases), adhesion (10 cases), partial invasion (8 cases) and total invasion (13 cases). The anterior floor of the third ventricle was involved in 42 cases, in which it disappeared totally in 10 cases. Total resection was achieved in 58 case, subtotal resection in 8 cases. Diabetes insipidus (DI) was identified in 44 cases postoperatively. No surgical mortality, no recurrence was found during follow-up of mean 35 months. ConclusionThe appropriate selection of surgical approaches preoperatively, careful identification and according treatment of the relationships of the tumors with pituitary stalks and hypothalamus are the keys to protect the pituitary stalk; hypothalamus in craniopharyngiomas resection in adults.

Fosmidomycin (100 micromol x L(-1)) which is the effective inhibitor of DXR, key enzyme in terpenoid MEP pathway, was used to treat with hairy roots of Salvia miltiorrhiza. The treated roots were harvested at 2, 4, 6, 8, 10, 16 and 21 d, mRNA level of SmDXR and tanshinone content in treated and negative control groups were detected. Results found that, after treated with fosmidomycin, color of S. miltiorrhiza hairy roots grew pale gradually comparing with controls; mRNA level of SmDXR in hairy roots varied as a shape of parabolic and the highest value achieved at the sixth day after treatment, then it decreased gradually; Content of four kinds of tanshinones were detected. Among of the four kinds of tanshinones, Tanshinone I content changed relatively little, while content of dihydrotanshinone I, cryptotanshinone and tanshinone II (A) decreased gradually in 21 days. The content of total tanshinones in NC groups was 5, 63 times more than FOS-treated roots in the 21th day. The previous results showed that SmDXR played an important role in the accumulation of tanshinone content in MEP pathway. Once the mRNA level of SmDXR was suppressed, the accumulation of secondary metabolites will be significantly affected.

Objective To compare endovenous laser therapy (EVLT) with endovenous microwave coagulation (EMC) in the treatment of varicose vein in the lower extremities. Methods Sixty-five (male 30, female 35) patients with 70 lower extremities (35 legs in each treatment group) were pair matched according to age, gender and CEAP classification to receive endovenous laser therapy (EVLT) or endovenous microwave coagulation (EMC). The same surgeon performed all procedures. Patients were monitored on 72 hours, 4 weeks and 6 months after the procedure (by procedural site scored for bruising, skin burn, painful induration or trabes as well as a pain score), the cured extremities were examined via Duplex uhrasonography to evaluate the effects of the procedure. Results All these 65 patients (mean age, 47.52 years) completed treatment and were followed-up. The mean operation time of EMC group was less than that of EVLT (71±25 vs. 59±15, P=0.01). At 72 hour after the procedure, bruising scores and skin buring were significantly different (P<0.05): patients in the EMC group showed less bruising (17.14% vs. 54.29%) but more burn (48.57% vs. 20%) on the procedure site than the patients in the EVLT group. At 4 weeks and 6 months after the procedure, no significant differences were found between patient outcomes, physical conditions, and symptoms and or possible adverse events. In 20/28 patients the pigmentation faded away, Edema were relieved in all the 25 extremities. 4 patients with ankle ulcer were healed. No major complications were found. Conclusions Both EMC and EVLT were effective in treating lower extremities varicose veins, with no major complications.

Objective To establish CFPAC-1 cell lines deficient in CDC25B2 by recombinant lentivirus, and to investigate the role of this gene. Methods After CFPAC-1 cells were transduced with recombinant lentivirus producing CDC25B2 siRNA, stably transduced cells with green fluorescent protein were selected by flow cytometer. The mRNA and protein expression of CDC25B2 was examined by RT-PCR and Western blot analysis. The effect of the lentivirus on the cell proliferation, cell cycle, clone-forming, migration and invasion ability was analyzed by MTr method, flow cytometer, plate clone-forming assay and Transwell chamber method respectively. Results CDC25B2 siRNA knocked down CDC25B2 expression in CFPAC-1 cells significantly. The silencing efficiency of siRNA transduction by recombinant lentivirns was very high. Proliferation, cloneforming, migration and invasion ability of human pancreatic cancer cell line CFPAC-I were significantly in-creased, while cell cycle was not affected. Conclusion CDC25 B2 plays an important role in cell proliferation, clone-forming, migration and invasion of pancreatic cancer. This research provides experimental evidences for targeting CDC25B2 in gene therapy against pancreatic cancer.
