The prediction of survival time for advanced cancer patients undergoing palliative care has important clinical and social value. The prediction of survival time of advanced cancer patients includes clinical prediction and statistical prediction. Due to the late start of palliative medicine in China, it is particularly important to evaluate the widely used survival prediction tools in clinical practice. In this paper, we will review the common survival prediction tools of advanced cancer patients from the perspective of Western and Traditional Chinese Medicine,to provide reference for development and application of a survival prediction system in China.

OBJECTIVE:To prepare nifedipine (NF) hollow controlled-release microspheres and evaluate the quality. METH-ODS:Solvent diffusion volatilization method was used to prepare microspheres,using comprehensive scores of cumulative release in 2,12,24 h(Q2 h,Q12 h,Q24 h)as indexes,orthogonal test was designed to screen the carrier material ethyl cellulose(EC),poly-vinyl pyrrolidone(PVP)and main drug NF amounts;appearance,particle size distribution,drug loading,floating and cumulative release of the microspheres prepared by optimal formulation were evaluated and compared of in vitro release behavior with imported preparation of Nifedipine controlled-release tablets (Adalat?). RESULTS:The optimal formulation was as follow as NF 3.00 g, PVP 1.60 g,EC 15.65 g. Prepared NF hollow controlled-release microspheres were spherical in shape with particle size distribution of 24-40 mesh and drug loading of 8.66%;24 h floating rate in release medium was 97.93%,Q2 h,Q12 h,Q24 h were 20.49%, 52.90%,91.00%(RSD<10%,n=3). Compared with the imported preparation,similarity factor f2 values of cumulative release were higher than 50,showing in vitro drug-release was consistent with the zero-order kinetic equation (r=0.9993);n of Rit-ger-Peppas equation (r=0.9807) was 0.478. CONCLUSIONS:Prepare NF hollow controlled-release microspheres show similar drug-release behavior with the imported preparation,the drug is released by the combination of diffusion and erosion.

Objective To compare the clinical effectiveness of external fixation,expert tibial nail (ETN) and minimally invasive percutaneous plate osteosynthesis (MIPPO) in the treatment of AO type 43A tibial fractures.Methods The clinical data of 102 patients with AO type 43A tibial fracture were retrospectively analyzed who had been treated from June 2010 to June 2014.They were 68 men and 34 women,from 18 to 71 years of age (average,36 years).By AO classification,there were 36 cases of type A1,45 ones of type A2,and 21 ones of type A3.External fixation was used in 30 cases,MIPPO in 42,and ETN in 30.The 3 groups were compared in terms of operation time,blood loss,fracture healing time,complications and functional evaluation according to American Orthopaedic Foot and Ankle Society (AOFAS) criteria for middle and fore foot.Results The operation time in external fixation group (72.7 ± 16.1 min) was significantly less than in MIPPO group (101.5±15.1 min) and ETN group (115.0±11.2 min) (P ＜0.05).The blood loss and fracture healing time in external fixation group were (320.6 ±40.8 mL) and (160.6 ± 25.0 days),significantly greater than in MIPPO group (125.5 ± 27.3 mL and 120.3 ± 20.2 days)and ETN group (124.2±25.4mL and 125.5±25.6 days) (P ＜0.05).The total complication rate in external fixation group (53.3％,16/30) was significantly higher than in MIPPO group (9.5％,4/42) and ETN group (10.0％,3/30) (P ＜ 0.05).The total AOFAS excellent to good rate in external fixation group (66.7％,20/30) was significantly lower than in MIPPO group (88.1％,37/42) and ETN group (90.0％,27/30) (P ＜ 0.05).However,there were no significant differences between MIPPO and ETN groups concerning all the above outcome indicators (P ＞ 0.05).Conclusions For AO type 43A tibial fractures,internal fixation should be the first choice.Both MIPPO and ETN can lead to good clinical efficacy.However,in cases where internal fixation is not suitable,external fixation with distal lateral tibial nails at the Chaput tuberosity can obtain satisfactory ankle function.

Objective:To discuss the level changes and significance of IL-2,IFN-γ,TNF-α in patients with bladder cancer.Methods:66 patients with bladder cancer who were treated in our hospital from February 2015 to December 2016 were enrolled in this study,which was denoted by bladder cancer group,65 patients with cystitis glandularis who were treated in our hospital during the same period were selected as cystitis group,another 65 healthy persons who were examined in our hospital during the same period were selected as control group,and compared the levels of IL-2,IFN-γ and TNF-α in each group,and the levels of IL-2,IFN-γand TNF-α in patients with bladder cancer of different types and clinical stages.The correlation of IL-2,IFN-γ and TNF-α levels with pathological types and clinical stages were analyzed.Results:The levels ofIL-2 and INF-γ in bladder cancer group were significantly lower than those in cystitis group and control group,the level of TNF-α was significantly higher than that of cystitis group and control group,the difference was statistically significant (P＜0.05).There was no significant difference in IL-2,IFN-γ and TNF-α levels in different types of bladder cancer patients (both P＞0.05).IL-2,IFN-γ levels in T2 to T4 bladder cancer patients were significantly lower than Tis to T1,TNF-α level was significantly higher than Tis to T1,the difference was statistically significant (both P＜0.05).According to Spearman method evaluation correlation founded that IL-2,IFN-γlevels in patients with bladder cancer were negatively correlated with clinical stage,TNF-α level was positively correlated with clinical stage.However,there was no correlation between IL-2,IFN-γ and TNF-α levels in patients with pathological type.Conclusion:IL-2,IFN-γ expression in bladder cancer patients are decreased significantly,while TNF-α expression is increased significantly,and the above three indexes of patients are related to clinical stage,but not related to pathological type.

Objective To investigate the independent factors influencing the efficacy of pre-hospital CPR effect. Method The data base with 1376 cases was set up with EpiData software by means of questionnaires and the information was provided by the survivals from cardiopulmonary arrest( CA)saved with cardiopulmonary resuscitation(CPR), and the data were analyzed with SPSS 13.0 software to carry out binary logistic regression. Through single factor analysis, the factors with emerged statistical significance were chosen as variances. Results With regard to the restoration of spontaneous circulation(ROSC), the rescue did by the first witness was the protective factor(PF)( OR = 2.21, P = 0.001, 95.0% CI=1.356-3.602); the male was the risk factor(RF) contrasted with the female( OR = 0. 515, P =0. 006, 95.0%0 CI = 0.320 - 0. 26) ; ages between 20 and 29 years old had higher likelihood of ROSC than group ≥81 years old( OR = 3.241, P = 0.026, 95.0%CI = 1.146 -9.138); the length of CA time before CPR was RF(OR = 0.913, P = 0.000, 95.0%CI = 0.887-0.948);ventricular fibrillation(VF) was PF compared with asystole( OR = 5.092, P = 0.000, 95.0%CI=2.927 -8.861); electric shock was PF(OR = 3.384, P = 0.000, 95.0%CI = 2.033 - 5.635); epinephrine dosage 0 - 4 mg had higher likelihood of ROSC than > 5 nag dosage( OR = 3. 255, P = 0. 001, 95.0% CI = 1. 606 -6.597). In respect of probability about victims at the tittle reached hospital alive, ages of 2- 12 and 13 - 19 years old had higher rations than ≥81 years old( OR = 12.818, P = 0.029, 95.0% CI = 1.299 - 126.508)( OR = 10.505, P = 0.036, 95.0% CI = 1.161-95.058); the length of CA time before CPR was RF(OR =0.862, P = 0.000, 95.0%CI = 0.821-0.906); VF was PF compared with asystole(OR = 7.330, P =0.000, 95.0%CI = 3.962 - 13.560). Conclusions ECG change before CPR, rescue by the first witness,electric shock, the length of CA time before CPR, epinephrine dosage, gender and age were independent influencing factors of pre-hospital CPR for the emergency of ROSC. Age, the length of CA time before CPR and ECG before CPR were influencing factors of pre-hospital CPR for patients at the time transferred to hospital alive.

Mitophagy is the process of selective clearance of damaged mitochondria by autophagy. There are several regulatory mechanisms for mitophagy, and the PINK1/Parkin pathway is considered the main pathway for mitophagy. Recent studies have shown that PINK1/Parkin-mediated mitophagy plays an important role in the pathogenesis of various diseases including Parkinson’s disease. This article introduces the mechanism of PINK1/Parkin-mediated mitophagy and its role in various liver diseases including nonalcoholic fatty liver disease, liver fibrosis, and hepatocellular carcinoma, in order to provide new clues and ideas for the treatment of diseases.
