Objective: To study the effects and the mechanism of isolinderalactone on inhibiting the growth of human breast cancer MCF-7 cells. Methods: Human breast cancer MCF-7 cells were cultured in vitro and treated respectively with indicated concentrations of isolinderalactone by cell culture technique. The proliferation rate was detected by MTT method; Flow cytometry and TUNEL assay were used to observe the effects of isolinderalactone on cell cycle, mitochondrial membrane potential and apoptosis in MCF-7 cells; The apoptosis related protein expression levels were determined by Western blotting. Results: Isolinderalactone significantly inhibited the proliferation of MCF-7 cells by inducing cell apoptosis in a time and concentration dependent manner and induced cell cycle arrest at G2/M phases. The mitochondrial membrane potential was depolarized; And isolinderalactone up-regulated the expressions of apoptosis related proteins Bax and cleaved Caspase-3 and down-regulated the expressions of apoptosis related proteins Bcl-2. Conclusion: Isolinderalactone shows obvious anti-cancer activities by inducing cell apoptosis. The mechanism of inducing apoptosis may be associated with the reduction of mitochondrial membrane potential and activation of caspase pathway.

AIM:To observe the efficacy of intravitreal conbercept injection for chronic central serous chorioretinopathy (CSC).METHODS: Nine eyes of 9 patients diagnosed as chronic CSC between October 2015 to May 2016 were treated with an intravitreal injection of conbercept (0.5mg/0.05mL) (six patients were given the same does of intravitreal injection again at 1mo after the first injection).Follow-up observation was at 1, 2, and 6mo after injection.Observed indicators included best-corrected visual acuity (BCVA), intraocular pressure, optical coherence tomography (OCT), fundus fluorescein angiography (FFA), choroidal indocyanine green angiography (ICGA), macular fovea thickness (CMT), subfoveal choroidal thickness (SFCT).RESULTS:Seven of the 9 patients responded significantly to the drug, while 2 patients had no response.The CMT was 373.12±72.43μm at baseline, which decreased significantly to 332.05±67.13μm, 282.24±62.30μm and 225.56±71.08μm at 1, 2 and 6mo after the intravitreal injection.The mean thickness of SFCT was 422.11±64.82μm before treatment.The choroidal thickness of non-responsive patients before treatment was below average, respectively 353μm and 365μm.The SFCT of 1, 2, and 6mo after treatment was 391.45±75.24μm, 365.53±63.07μm, 355.40±66.65μm.Before treatment and 1mo after, there was no significant difference (P=0.074), but there was statistically significant (P<0.01) between those of before and 2mo and 6mo after.The mean BCVA of the prior treatment was 0.53±0.32, the after treatment was 0.65±0.20, there was no different between the two(P>0.05).CONCLUSION: Intravitreal conbercept injection in chronic CSC may have some effect in accelerating subertinal fluid resolution and decreasing the CMT.The SFCT within 6mo after treatment was significantly lower than pretreatment.The SFCT may be an indicator of whether patients respond.

OBJECTIVETo explore the function and motor pathway of remained cerebral hemisphere by studying motor evoked potential of both upper extremities on patients long term after anatomical hemispherectomy.

METHODSFive patients after anatomical hemispherectomy, who were marked 5 dispersive sites on head to perform transcranial magnetic stimulation. Recording motor evoked potential of target muscles (brachioradialis muscle and abductor pollicis brevis) of both upper extremities respectively when muscle resting and contracting.

RESULTSOnly affected abductor pollicis brevis of case 2 and only affected brachioradialis muscle of case 4 and 5 recorded motor evoked potential when muscle resting. Motor evoked potential of some cases can be recorded simultaneously in homonymous muscles of both sides when muscle resting or contracting.

CONCLUSIONSThere exists motor cortex that controls movement of ipsilateral limbs and also ipsilateral motor pathway of corticospinal connection at patients after anatomical hemispherectomy. It also means that the motor function of affected limbs has potency to recover well after hemispherectomy. The mirror movement after hemispherectomy is possible relate to overlap of both limbs' motor cortex.

OBJECTIVETo analyze initial response rate of radiotherapy and chemotherapy for early nasal NK/T-cell lymphoma, and its prognostic factors.

METHODSFrom January 1996 to December 2002, 116 patients with nasal NK/T-cell lymphoma were diagnosed pathologically. Immunophenotyping was performed in 50 cases. According to Ann Arbor staging classification, 95 patients were stage I(E) and 21 II(E). Of the 116 patients, 22 received radiotherapy alone, 6 chemotherapy alone and 88 combined modality therapy (CMT), including, 41 radiotherapy followed by chemotherapy, and 47 chemotherapy followed by radiotherapy.

RESULTSThe 5-year overall survival (OS) rate and disease free survival (DFS) rate for all patients was 74.1% and 61.5%, respectively. For stage I(E) and II(E) patients, the 5-year OS rate was 75.1% and 68% (P = 0.45), and DFS rate was 64.7% and 47.8%, respectively (P = 0.07). The 5 year OS rate and DFS rate were 86.5% and 71.5% for patients who achieved complete response (CR), and 18.4% and 17.2% for those who didn't, respectively (P = 0.000). Sixty-three patients were treated with radiotherapy alone or radiotherapy followed by chemotherapy, while 53 with chemotherapy followed by radiotherapy or chemotherapy alone. The CR rate for radiotherapy was 74.6% while for chemotherapy was 20.8% (P = 0.000). The 5-year OS rate and DFS rate were 76.8% and 65.4% for radiotherapy with or without chemotherapy, and 78.8% and 61.8% for chemotherapy followed by radiotherapy (P > 0.05). Multivariate analysis by COX regression showed that CR rate was the only independent prognostic factor.

CONCLUSIONThe CR rate of radiotherapy is much higher than that of conventional chemotherapy. Addition of chemotherapy to radiotherapy do not improve the survival of patients with early stage nasal NK/T-cell lymphoma. Radiotherapy is the primary treatment for stage I and II nasal NK/T-cell lymphoma.

OBJECTIVETo explore the effects of ytterbium citrate on human liver carcinoma HepG2 cell line and the potential mechanisms.

METHODSThe HepG2 cells were cultured with DMEM medium and divided into different groups in the following media, in serum-free medium as control, different concentration (0.01 - 5.00 mmol/L) [YbCit(2)](3-)+serum-free medium as treatment group, MTT assay was used to measure the viability of the cells; 2.00 mmol/L [YbCit(2)](3-)+serum-free medium was used as treatment group, and Hoechst 33258 staining was used to detect apoptosis in HepG2 cells. Differential proteomic analysis, assay of intracellular H(2)O(2) levels and mitochondrial transmembrane potential were performed to study the effects of [YbCit(2)](3-) on HepG2 cells and the potential mechanisms.

RESULTSThe data showed that 72 h treatment of [YbCit(2)](3-) at 2.00 - 5.00 mmol/L significantly inhibited cell proliferation, and the IC(50) was (2.46 ± 0.23) mmol/L. After treatment with 2.00 mmol/L [YbCit(2)](3-) for 48 h and 72 h, Hoechst 33258 staining demonstrated that [YbCit(2)](3-) induced significantly increased apoptosis in HepG2 cells. After treatment with 2.00 mmol/L [YbCit(2)](3-) for 72 h, two dimensional gel electrophoresis and MALDI-TOF mass spectrometry analysis revealed 14 differentially expressed proteins between [YbCit(2)](3-)-treated cells and the control cells. These proteins mainly included cofilin1, peroxiredoxin6, S100 calcium-binding protein A6, and proteasome 26S non-ATPase subunit 13 isoform 3 and so on. These proteins played important roles in the processes of anti-apoptosis, oxidation reduction, cell proliferation and protein degradation. The mitochondrial membrane potential were investigated, the results showed the red and green fluorescence ratio was 2.45 ± 0.28 in the control group, 1.56 ± 0.23 in 24 h group, 1.16 ± 0.18 in 48 h group, compared with the control, the differences were significant (F = 23.97, P = 0.001). The results of H(2)O(2) detection showed the fluorescence intensity was 20.00 ± 2.08 in the control group, 40.00 ± 5.50 in 24 h group, and 48.00 ± 2.03 in 48 h group, compared with the control, the differences were significant (F = 48.40, P = 0.000). The results indicated a significant reduction in mitochondrial transmembrane potential and significant increase in H2O2 generation were observed in [YbCit(2)](3-)-treated cells.

CONCLUSIONThese results suggested that [YbCit(2)](3-) could induce apoptosis of HepG2 cells through the mechanisms involving oxidative stress and mitochondrial dysfunction.
