Objective:To evaluate the effects of chemotherapy on survival of patients with inoperable hepatocellular carcinoma. Methods:MEDLINE and EMBASE searches were supplemented by information from trial registers. RCT (randomized clinical trial) for chemotherapy of old generation and best supportive care in inoperable hepatocellular carcinoma was selected. Best supportive care may include some non-cytotoxic drug,such as tamoxifen,octreotide and so on. A quantitative meta-analysis using updated information basing on inclusion and exclusion criterion from all available RCT was carried out by two reviewers. The meta-analysis was based on 6 months survival rate and 1 year survival rate. Result:There was no significant improvement for chemotherapy of old generation in 6 months survival rate and 1 year survival rate as compared with best supportive care. Conclusions:There is no convincing evidence that inoperable hepatocellular carcinoma patients will benefit from chemotherapy. A large number of randomized controlled clinical studies should be performed to confirm the efficacy of chemotherapy.

Objective To evaluate the levels of oxidative stress in patients undergoing long-term and repetitive exposure to hyperbaric oxygen (HBO) treatment. Methods 16 healthy volunteers and 58 patients with sub-acute sudden hearing loss (SHL) exposed to HBO were included in the study. Oxidative stress indices (malondialdehyde, MDA, advanced oxidation protein products, AOPP; superoxide dismutase, SOD) were measured in peripheral blood samples collected at the 5th,10th, 20th and 30th HBO treatments sessions (PO2 0.18 MPa, 1 session per day and 5 sessions per week) and under normal ambient pressure respectively. Results After 5th,10th, 20th and 30th sessions of HBOT, no relevant differences in these three indices were detected compared to pre-HBO exposure, between healthy volunteers (P > 0.05). Conclusions The long-term repetitive HBO treatment for 0.18 MPa of PO2 and 30 sessions could not affect in particular the response of the oxidative stress in healthy persons and patients with sub-acute SHL. The influence on three indices of patients with abnormal situation of oxidative stress undergoing lower pressure of HBO (0.18 MPa) is under investigation.

Objective:To explore whether there were changes in midbrain morphology related to motor function in patients with cerebral small vessel disease (CSVD).Methods:The study was conducted on a subset of patients with CSVD registered at the Department of Neurology of Peking Union Medical College Hospital from 2010 to 2018. All magnetic resonance imaging images were taken with a 3.0 T nuclear magnetic resonance imager. The measurement of anteroposterior diameter of the mesencephalon and the tegmentum of mesencephalon was performed on a personal computer with the image processing software RadiAnt DICOM Viewer. Several clinical manifestations of dyspraxia, dysphagia, dysarthria and dysuria were evaluated by interviewing the patient and family members living with the patient. Kinect depth camera combined with self-developed software platform was used to conduct quantitative evaluation of patients′ motor function. Three parameters, namely walking speed, walking time of three meters and time of standing up and sitting down, were selected from the obtained parameters. SPSS 17.0 software was used for statistical analysis.Results:A total of 176 patients were included, aged 30-88 (64.16±11.57) years. One hundred and fifteen patients were males, accounting for 65.34%. In patients with CSVD, anteroposterior diameter of the mesencephalon and the tegmentum of mesencephalon were negatively correlated with age ( B=-0.032, P<0.001; B=-0.020, P=0.006). The anteroposterior diameter of the mesencephalon was negatively correlated with symptoms of dyskinesia ( OR=0.006, 95% CI 0-0.135, P=0.001), even when the age and gender were adjusted ( OR=0.014,95% CI 0-0.416, P=0.013). The anteroposterior diameter of the mesencephalon was negatively correlated with symptoms of dysuria ( OR=0.046,95% CI 0.002-0.936, P=0.045), but no longer correlated when the age and gender were adjusted. The anteroposterior diameter of tegmentum of mesencephalo was also negatively correlated with symptoms of dyskinesia ( OR=0.035,95% CI 0.002-0.684, P=0.027), but no longer correlated after adjusting for age and gender. Video recording and evaluation of motor function were performed on 87 patients. Spearman correlation analysis showed that none of the three motor function scores was correlated with age or gender. The anteroposteric diameter of the midbrain was positively correlated with walking speed ( r=0.231 ,P=0.040) and negatively correlated with walking time of three meters ( r=-0.304, P=0.005), but not with standing up and sitting down time, while the anteroposteric diameter of tegmentum of mesencephalo was not correlated with all of them. Conclusion:There are changes in mesencephalon morphology in patients with CSVD, structural parameters of mesencephalon are related to motor function and urination function, and mesencephalon atrophy may be an independent related factor for symptoms of dyskinesia in patients with CSVD.

To have a thorough understanding of the CPR quality based on patients' various physiological states, the doctors must do something to simulate the chest compression physiological feedback parameters (CCPFP). The CCPFP simulation plays an important role in raising efficiency of CPR training and improving chest compression quality. In this study, the CCPFP, including cardiac output (CO), coronary perfusion pressure (CPP), partial pressure of End-tidal CO2 (PETCO2) and mean arterial relaxation pressure (MARP), was simulated using Charles F. Babbs' Model. Simulation results showed that the effect of compression depth upon CCPFP was important in the range of 2-6 cm, whereas compression rate had little effect on the CCPFP higher than 100/min; the thoracic factor is inversely proportional to the CCPFP with fixed compression depth and compression rate. The CCPFP simulation can be implemented at the various physiological statuses, and verified well with the animal experimental results and the clinical results.

Objective To evaluate the clinical efficacy and safety of nanoparticle albumin-bound paclitaxel (Nab-P) in the treatment of advanced non-small cell lung cancer (NSCLC). Methods Fifty-six over 65 years old patients with advanced NSCLC treated with Nab-P monotherapy in department of chemotherapy of the People's Hospital of Zhongshan City from January 2014 to January 2017 were analyzed retrospectively. The chemotherapy regimen was Nab-P 260 mg/m2, on d1 or d1 + d8, every 21 day for a cycle, imaging examination was made for efficacy evaluation after every 2 cycles. Results All 56 patients had been evaluated for efficacy, and received a total of 186 cycles of chemotherapy. All patients had been completed 2 cycles or more than 2 cycles of chemotherapy, and the median number of chemotherapy cycles was 3. The treatment response rate (RR) was 25.0 ％ and the disease control rate (DCR) was 76.8 ％. The median progression free survival (PFS) time was 4.7 months. The main adverse reactions were neutropenia, nausea and vomiting, fatigue and peripheral nerve toxicity. However, the vast majorities of adverse reactions were grade 1-2, and can be improved after treatment. Conclusions Nab-P is effective in the treatment of advanced NSCLC in elderly patients. The adverse reactions are mild and tolerant, and it is worthy to be popularized.

Objective: To explore the effect of long term aerobic exercise on microcirculation function and VO 2max of college students, and to explore the relationship between microcirculation function and VO 2max . Methods: Seventy sports major college students were selected as the exercise group, 70 sedentary non sports major students were selected as the control group. PF6000 dual channel laser Doppler blood flow detector was used to assess the skin microcirculation function on the quadriceps femoris muscle of the subjects right lower limbs.The PFT Ergo cardiopulmonary function test system and the equipped power bicycle were used to measure the VO 2max of the subjects. Results: The baseline value of MBP in the exercise group was significantly lower than that in the control group (6.5±1.8 vs. 8.1±2.5), but the microvascular reactivity(1 666.3±588.6 vs. 1 165.2±407.1) was significantly higher than that in the control group(t =-3.42，4.46， P <0.01). The absolute value of VO 2max (2 684.8±451.1 vs. 2 474.4±423.5) and relative value (42.7±4.3 vs. 35.1±4.8) in exercise group were significantly higher than those in control group( t =2.16，3.25， P < 0.01 ). Multiple regression showed that there was a positive correlation between microvascular reactivity and VO 2max (relative value) ( β = 0.40 , P =0.03), but no significant correlation between percutaneous oxygen partial pressure and VO 2max (relative value) ( β= 0.23 , P =0.19). Conclusion Long term physical exercise can decrease microcirculation perfusion volume, improve microvascular reactivity, percutaneous oxygen partial pressure among college students. Improvement of the microvascular reactivity may be a sport improving VO 2max (relative) one of the most important peripheral physiological mechanism.
