Objective To investigate the expression and clinical significance of zinc finger protein 217 (ZNF217)in human pancreatic cancer.Methods 43 cases with pancreatic cancer undergoing surgery in the PLA 117 Hospital and People's Hospital of Ruian City from Apr .2011 to May.2014 were enrolled in the study . The pancreatic cancer and the corresponding tumor-adjacent tissues were collected .Real-time quantitative PCR (qRT-PCR)was applied to detect ZNF217 mRNA expression in pancreatic cancer (n=43)and the corresponding tumor-adjacent normal tissues.The protein expression of ZNF217 was measured by immunohistochemistry(IHC). The relationship between the expression of ZNF 217 and clinical features was analyzed by pearson chi-square test . Results The expression level of ZNF217 mRNA and protein was significantly higher in pancreatic cancer tissues than in adjacent normal tissues(P<0.05).The high expression of ZNF217 protein was positively correlated with perineural invasion, tumor size, lymphatic metastasis and advanced TNM stage (P<0.05).Conclusions The expression of ZNF217 is significantly higher in pancreatic cancer tissues than in tumor-adjacent normal tissues , and the upregulation of ZNF 217 is associated with clinicopathological features of tumor malignance .ZNF217 may become a new marker and effective therapeutic target in early diagnosis of pancreatic cancer .

AIM: To evaluate the clinical outcomes in terms of vision across distances(near, intermediate and far), contrast sensitivity and subjective patient satisfaction after femtosecond laser-assisted cataract surgery(FLACS)with implantation of an extended range of vision(ERV)intraocular lens(IOL).

METHODS: Forty patients(55 eyes)underwent bilateral or monocular FLACS with implantation of the ERV IOL Tecnis Symfony(Johnson & Johnson Vision)were enrolled. Uncorrected distance(UDVA), intermediate(UIVA)and near visual acuities(UNVA)were evaluated at 3mo after surgery, as well the defocus curve, contrast sensitivity, patient satisfaction and spectacle independence.

RESULTS:No severe complications occurred. All eyes showed a central position of the IOL in the capsular bag without tilting at 3mo after surgery. 3mo postoperative mean logMAR visual acuity at 5 m, 67 cm and 40 cm were -0.04 ±0.08, -0.17±0.22, 0.37±0.17, respectively. All patients obtained satisfactory UDVA and UIVA, as well as functional UNVA, meeting the needs of daily life. Spectacle independence rate was 94.55%. Contrast sensitivity results did not differ from those obtained with monofocal aspheric lenses. Likewise, no moderate and severe photic phenomena were reported. Mean patient satisfaction scores with distance, intermediate and near vision were 9.0, 9.0, and 7.0, respectively.

CONCLUSION: FLACS with implantation of the ERV IOL TECNIS Symfony provides a successful visual restoration at far, intermediate distance and a functional-range near vision acuity, with minimal level of disturbing photic phenomena, and high rates of spectacle independence and patient satisfaction.

Objective To establish a surgical risk prediction model for in-hospital mortality of adult rheumatic heart disease.Methods The study sample comprised of 3 889 patients with adult (is, or older than 18 years) rheumatic heart valve surgery only.All patients were divided into three subgroups according to the surgery site of left atrioventricular valve: mitral valve surgery group;aortic valve surgery group;and mitral and aortic valve surgery group.The data was splited into development(60％) and validation(40％) data sets, and then the risk model was developed by using a logistic regression model according to the data in development data set.Model calibration was analyzed by Hosmer-Lemeshow goodness-of-fit statistic, and model discrimination was tested by calculating the area under the receiver operating characteristic(ROC) curve.Risk score was finally set up according to the coefficient β and rank of variables in logistic regression model.Results The general in-hospital mortality of the whole group is 4.2％ (165/3 889).We established a risk prediction model and found seven risk factors: heart function in NYHA functional class ≥ Ⅱ grade (OR =3.36, 95％ CI: 2.42-4.67) , preoperative creatinine ＞ 110 mmoL/L (OR =2.69, 95％ CI: 1.51-4.79) , history of previous chest pain(OR =2.33, 95％ CI: 1.07-5.11) , surgical status(OR =2.32, 95 ％ CI: 0.94-5.73) , previous history of hypertension (OR =2.24, 95 ％ CI: 1.19-4.23), preoperative critical state (OR =2.14, 95％ CI: 1.27-3.60) and age ＞ 50 years (OR =1.57, 95 ％ CI: 1.18-2.09).Our risk model showed good calibration and discriminative power for the development data set, validation data set, and three subgroup in which Hosmer-Leme-show test' s P value were greater than 0.05 and the area under the ROC curve were greater than 0.70.Scoring methods: age 51-60years: 1 point, age 61-70 yeas: 2 points, age ＞70 years: 3 points;history of hypertension: 1 point;creatinine ＞ 110 umol/L: 4 points;NYHA class stage Ⅱ : 2 points, NYHA class stage Ⅲ: 4 points;NYHA class stage Ⅳ: 6 points;history of previous chest pain: 1point;preoperative critical condition: 2 points;urgent surgery: 2 points: emergency surgery: 4 points.Conclusion We have created a new risk prediction model and risk score, which can accurately predicts outcomes in patients undergoing heart valve surgery for our center.Furthermore, our risk model can also enable benchmarking and comparisons between multicenter in a meaningful way in the future.

Objective To explore the clinical outcomes of different mild-stimulation in poor ovarian responders in vitro culture/intracytoplasmic injection (IVF/ICSI) to provide the evidence for clinical treatment,and investigate clinical parameters including pre-ovulation rate,rate of oocytes retrieved,fertilization rate,good quality embryo rate,and pregnancy rate per cycle.Methods The clinical date of a total 180 IVF cycles of infertile patients undergone from Jan 2013 to May 2016 in medical reprodution center of Xiang Tan Central Hospital.According to the different methods of controlled ovarian hyperstimulation (COH),the cycles were divided into 3 groups:group A with 60 cycles of early five days using clomiphene,group B with 60 cycles of persistent using clomiphene,and group C with 60 cycles using artificial luteal-phase ovarian stimulation protocol.Results The basic situations in three groups were no significant difference (P ＞0.05).Compared to groups B and C,the pre-ovalution rate was more in group A (P ＜ O.05),and the rate of oocytes retrieved,fertilization rate,good quality embryo rate,and preganacy rate per cycle were higher in groups B and C (P ＜ 0.05).The rate of oocytes retrieved,fertilization rate,good quality embryo rate,and preganacy rate per cycle were no significant difference among gourps B and C.The good quality embryo rate and preganacy rate per cycle in groups B and C were higher than group A,and group B was higher than group A (P ＜ 0.05).Conclusions Persistent using clomiphene or persistent using clomiphene in COH could decrease the rate of pre-ovalution,and get more rate of oocytes retrieved,good quality embryo rate,and preganacy rate per cycle.

ObjectiveTo explore the effect of acupuncture combined with training of the modified rehabilitation apparatus on upper limb motor function of patients with ischemic stroke.Methods86 patients with ischemic stroke were divided randomly into the treatment group ( treated by acupuncture combined with training of the rehabilitation apparatus) and the control group (treated by simple acupuncture). The upper limb motor function of two groups was evaluated by Fugl-Meyer Assessment (FMA) before and after treatment.ResultsAfter 28 days treatment, scores of FMA of two groups were all raised significantly, but it was significantly greater for the treatment group than the control group (P<0.01).ConclusionIt is shown that acupuncture combined with training of the rehabilitation apparatus can improve the upper limb motor function and activity of daily living of patients with ischemic stroke.

OBJECTIVETo investigate the protective effect of mouse astrocyte-conditioned medium (ACM) on hypoxic and mechanically injured neurons by a cell model in vitro, and to explore the possible mechanism.

METHODSThe model of hypoxic neuronal injury was caused by 3% O2 in three-gas incubator. Neurons were cultured with ordinary medium or 20% ACM respectively and randomly divided into hypoxic group (hypoxia for 4, 8, 24 h and marked as H4R0, H8R0, H24R0) and hypoxia reoxygenation group (H4R24, H8R24, H24R24). Mechanical injury model was developed by scratching neurons cultured in 20% ACM or ordinary medium to different degrees. Neurons in both medium were divided into normal control group, mild, moderate and severe injury groups. The 20% ACM was added 24 h before hypoxia/reoxygenation or mechanical injury. The morphology and survival of neurons were observed and counted by trypan blue staining. The concentration of NO, lactic dehydrogenase (LDH) and membrane ATPase activity were detected by corresponding kits.

RESULTSIt was showed that 20% ACM can obviously promote the survival rate of hypoxia/reoxygenated neurons and scratched neurons as well. The morphology and number of neurons exposed to hypoxia or scratch injury showed great difference between groups with or without ACM treatment. Compared with control group, the concentration of NO and LDH was much lower in hypoxic/reoxygenated neurons treated with 20% ACM, and the ATPase activity was higher. For the mechanical injury model, neurons with moderate injury also revealed a lower NO and LDH concentration than the control group. All the differences were statistically significant (P less than 0.05).

CONCLUSIONACM can promote the survival and functional recovery of neurons following hypoxia or scratching to a certain degree. The mechanism may be associated with reducing the synthesis and release of NO and LDH as well as increasing the activity of membrane ATPase.

Objective: Cell cycle has recently become more appealing as a new target of anti-carcinogen-ic agent. Diallyl disulfide (DADS) inhibits growth and induces call cycle G_2/M arrest in human gastric cancer BGC823 cells. Cell division cycle protein 25C (Cdc25C) and CyclinB1 expression are involved in G_2/M arrest.However, mechanisms of G_2/M arrest are not yet fully understood. The aim of this study was to elucidate the mechanism of cell cycle G_2/M arrest in human gastric cancer BGC823 cells induced by DADS. Methods: The expression of chk1 and Chk2 mRNA associated with cell cycle arrest of BGC823 cells after the induction with DADS for 1 or 2 days was detected by RT-PCR. The protein expression of cycle-related proteins ATM-RAD3-related gene (ATR), checkpoint kinase1 (Chk1), checkpoint kinase 2 (Chk2), P-ATR, P-Chk1 and P-Chk2 was measured by Western blot. Interaction between Chk1/2 and Cdc25C was analyzed by immuno-precipitation. Results: After the cells were treated with 15 mg/L DADS for 1 or 2 days, the expression of Chk1 and Chk2 mRNA was not significantly different from that in untreated cells (P>0.05). Western blot analysis showed that the expression of total Chk1 and Chk2 treated with 15 mg/L DADS was not significantly different from that in untreated cells. But phospho-chk1 showed a significant increase after stimulation with 15 mg/L DADS for 2h to 12h and continued to increase gradually as time went on (P<0.05). Phospho-Chk2 showed a eak expression and a weaker expression after stimulation with DADS, but the changes were not statistically significant (P>0.05). Addition of 15 mg/L DADS to BGC823 cells for 15 rain to 120 min resulted in an increase in phospho-ATR expression, whereas no changes were found in ATR expression (P<0.05). The Chk1 Ab in-creasingly precipitated Cdc25C in BGC823 cells treated with DADS (P<0.05). In contrast, Chk2 Ab failed to change precipitation with Cdc25C by DADS (P>0.05). Conclusion: Activation of chk1 was involved in cell cy-cle G_2/M arrest in BGC823 cells treated with DADS. Cell cycle G_2/M arrest by DADS is associated with phos-phorylation of several cell cycle regulatory proteins including ATR and Chk1 which regulate expression of Cdc25C.
