Parkinson's disease(PD) is one of the most common neurological degenerative diseases with unknown causes and pathogenesis,and may be associated with genetic and environmental factors.Recent studies showed that PD had genetic basis.Genetics research of PD has been a hot topic nowadays,which provides hope for revealing the pathogenesis of PD.

The bladder meridian of foot-taiyang is considered as key of six meridians and the yang of the yang, which is the pivot of transportation for qi and blood in the meridians and zang-fu. The running route and treatment characteristic of bladder meridian is closely related with chronic fatigue syndrome (CFS). The bladder meridian belongs to brain and connects with governor vessel, which has a close relationship with zang-fu function, quality of sleep and fatigue. Besides, the running route of bladder meridian is highly consistent with the surface projections of important anatomical structures such as muscle, nerve and sympathetic trunk, etc. Therefore, regulating the meridian-qi of bladder meridian can harmonize five-zang and calm the mind, but also effectively relieve physical and mental fatigue in CFS.

Objective To investigate the effect of resveratrol on autophagic flux of nasopharyngeal carcinoma CNE-2 cells, and to explore the underlying mechanism. Methods Nasopharyngeal carcinoma CNE-2 cells were divided into control group and resveratrol group. Cells in control group were normally cultured at 37℃and received no further treatment. Resveratrol group was added 40 μmol/L resveratrol 2 h before cells were culture at 37 ℃. Western blot analysis was performed to detect protein expressions of LC3B, p62, Beclin-1, phospho-mTOR (p-mTOR) and phospho-S6 (p-S6). The autophagic flux was detected under the confocal laser scanning microscopy through different color spots, after cells were transfected with adenovirus encoding GFP-mRFP-LC3. Results (1) The protein expression of LC3B was significantly increased and the protein expression of p62 was significantly decreased in resveratrol group compared with those of control group (P<0.05). There was no significant difference in Beclin-1 expression between two groups. (2) Compared to control group, expressions of p-mTOR and p-S6 were significantly decreased in resveratrol group (P<0.05). (3) Compared to control group, the red mRFP puncta were significantly increased, and the yellow GFP puncta were significantly decreased in resveratrol group (P<0.05). Conclusion Resveratrol promotes the autophagic flux of nasopharyngeal carcinoma CNE-2 cells, and the effects are possibly dependent on the activation of mTOR pathway-related proteins.

Objective To explore the therapeutic efficacy of the water soluable photosensitizer D-galactopyranosyl zinc phthalocyanines (T1)-mediated photodynamic therapy (PDT) applied to HepG2 human hepatocellular carcinoma cells in vitro and in vivo,as well as its mechanism.Methods HepG2 cells in their logarithmic growth phase were cultured and divided into different concentrations ofT1 (0 μM,0.06 μM,0.125 μM,0.25 μM,0.5 μM and 1 μM).Methyl thiazolyl tetrazolium (MTT) assays were employed to determine the effect of the T1-PDT on the proliferation of the HepG2 cells.Cell apoptosis and necrosis were measured using a cell analyzer with Annexin VFITC/PI/Hochest33342 triple-staining.The reactive oxygen species (ROS) and the mitochondrial membrane potentials of the HepG2 cells were detected using fluorescence microscopy.Confocal microscopic assays were used to observe T1's subcellular localization on the HepG2 cells.Real-time quantitative polymerase chain reactions (RT-PCRs)were used to detect any apoptosis of Bcl-2-and Bax-related genes.H-22-bearing mice were used to calculate the antitumor rate of T1-PDT,and the expression levels of Bcl-2 and Bax mRNA were detected using RT-PCRs.Twenty-four healthy mice were randomly divided into a control group,a low-dose group,a middle-dose group and a high-dose group,each of 6.Each group was given different doses of T1-PDT and the tumor inhibition rate was calculated.Results The MTT assays showed that T1-PDT could significantly inhibit HepG2 cell growth,but T1 or PDT alone had little effect.The confocal microscope assay showed that T1 was mainly localized in the mitochondria in HepG2 cells with little in the lysosome.Cell analyzer results showed that T1-PDT could induce HepG2 apoptosis.The ROS levels of HepG2 cells increased after T1-PDT.The RT-PCR results showed that T1-PDT could increase the expression of Bax and decrease the expression of Bcl-2.The in vivo experiments demonstrated that T1-PDT significantly inhibited the growth of H-22-xenografied tumors.Conclusions T1-mediated PDT has a significant lethal effect on HepG2 cells in vitro and in vitro.The lethal effect of PDT on cancer cells is shown in the apoptosis and can be attributed to T1's subcellular localization in the mitochondria,increasing ROS levels,and regulating apoptosis-related genes.

Objective To investigate the causes of diarrhea during autologous peripheral blood stem cell transplantation (APBSCT )and summarize the nursing strategies.Method The histories of 23 APBSCT patients suffering from diarrheas were retrospectively reviewed to find out the causes of diarrhea and summarize the nursing strategies.Results The main causes of the diarrheas included the toxicity of pretreatment chemotherapy drugs in 15 cases,antibiotics in 2 cases,gastrointestinal motility drugs in 2 cases,intestinal infections from decreased immunity in 2 cases and other diseases in 2 cases,all recovered by corresponding managements.Conclusions APBSCT-associated diarrheas may be caused by chemotherapy drug toxicity,infections,drugs and other factors.So the nurses should evaluate them correctly,adopt corresponding nursing measures,strengthen the observation of patients' condition and raise awareness of prevention for the purpose of reducing the incidence of diarrhea,promoting the recovery of patients and improving the quality of life.

Objective To investigate the clinical value of clinical application in diagnosis of prostate cancer (PCa) by prostate biopsy guided by rectal ultrasound contrast guided biopsy.Methods One hundred and ninety-eight patients with prostate in Punan Hospital of Pudong New District of Shanghai were investigated.According to different detection methods, the research objects were divided into two groups, the patients were performed with the ultrasound contrast guided biopsy as the imaging group (n =96), the patients with Doppler ultrasound guided biopsy as the ultrasonic group(n =102).The puncture Results were compared with pathological diagnosis.The positive rate of PCa and number of puncture needle were compared with the two puncture methods.The value of the application of the prostate biopsy guided by rectal ultrasound in diagnosis of prostate cancer was evaluated.Result One hundred and ninety-eight patients were all received pathological diagnosis,78 cases benign lesions, 120 cases were diagnosed as PCa.Thirty-six cases of benign lesions were confirmed by pathological biopsy, 60 case PCa.There were 42 cases of benign lesions in ultrasonic group, 60 case PCa.The positive rate of PCa in the imaging groupwas 62.5％ (60/96), the ultrasonic group was 58.82％ (60/102).There was no difference in Pca positive rate between the ultrasound group and the contrast group(x2 =0.104, P=0.747).The positive number of Pca in the imaging group was 28.50％ (17/60), the difference was statistically significant higher than that of the common group(18.80％ (11/60), P =0.001).The average of the patients in the imaging group was 8.19 needle,less than the ultrasonic group per capita 11.31 needle less.When f/tPSA less than or equal to 0.15, Pca positive rate of the contrast group was 46.55％ (27/55), higher than the ultrasonic group(9.30％ (4/43)), the difference was statistically significant (P =0.001);when f/tPSA more than 0.15, the positive rate of Pca in the contrast group was 92.11％ (35/38), less than the ultrasound group (94.92 (56/59)), the difference was not statistically significant (P =0.89).Anal pain, hematuria and hematochezia in contrast group (7.29％ (7/96), 2.08％ (2/96), 10.42％ (10/96)) were significantly less than the ultrasound group(22.55％ (23/102), 8.82％ (9/102), 23.53％ (24/102)), the difference was statistically significant (P =0.003,0.039,0.014).Conclusion Under the guidance of ultrasound contrast, rectal biopsy has important diagnostic value for prostate cancer.Under the premise of reducing the number of puncture needle,can improvethe positive rate of Pca, reduce the pain of patients and the occurrence of complications after puncture.When f/tPSAless than or equal to 0.15,puncture positive rate in contrast group is higher than the ultrasonic group, puncture effect is better.

OBJECTIVETo study the radiosensitizing effect of resveratrol on hypopharyngeal carcinoma cell line FADU in vitro.

METHODSHypopharyngeal carcinoma cell line FADU was cultured in in vitro DMEM. Its inhibition on cell proliferation was detected using cytotoxicity test (MTT assay). The cell survival curve was drawn using clone formation to obtain sensitive enhancement ratio (SER). Changes of the cell cycle and cell apoptosis were analyzed using flow cytometry (FCM).

RESULTSResults of MTT showed the inhibition of resveratrol on FADU cells increased along with its concentrations (P < 0.05). Results of clone formation indicated the surviving fraction at 2 Gy (SF2) was 0.717 ± 0.062 in the irradiation group, and 0.426 ± 0.035 in the resveratrol plus irradiation group (with SER ranged 1.684 ± 0.178) with statistical difference (P = 0.007). Results of FCM showed that after radiation of 4 Gy radiation, cells at G2/M phase arrest increased, but cells at G1 decreased. After radiation of resveratrol for 24 h, cells at G1 decreased, but cells at G2/M phase and S phase arrest increased. When 4 Gy radiation combined resveratrol was used, cells at G2/M phase arrest significantly increased, but cells at G1 significantly decreased. The apoptosis rate was 1.94% ± 1.65% in the control group, 4.56% ± 0.92% in the irradiation group, 2.03% ± 1.46% in the resveratrol group, and 23.11% ± 7.22% in the resveratrol plus irradiation group. There was statistical difference between the resveratrol plus irradiation group and the rest 3 groups (P < 0.05).

CONCLUSIONResveratrol could enhance the radiosensitivity of hypopharyngeal carcinoma FADU cells in vitro possibly by inducing cell apoptosis and causing changes in the cell cycle distribution.
