Objective To evaluate the impact of postoperative adjuvant chemotherapy on prognosis of patients with advanced rectal carcinoma using a meta-analysis.Methods We searched PubMed to identify literature comparing observation with adjuvant chemotherapy after neoadjuvant chemoradiotherapy and surgery for patients with advanced rectal carcinoma.Data were analysed using Revman 5.0 statistical software.Results Nine trials were included consisting of 6 212 patients:3 421 patients received adjuvant chemotherapy and 2 791 patients did not.The age ranged from 55.6 to 68 years.Adjuvant chemotherapysignificantly affects overall and disease-free survival (P =0.002 and P =0.000 5 respectively) of patientswho had received neoadjuvant chemoradiotherapy.The subgroup analysis which originate from insufficient data reveales ypT0-2 patients and ypT3-4 patients can't benefit from adjuvant chemotherapy.Conclusion Postoperative adjuvant chemotherapy can improve the survival of advanced rectal carcinoma patients after neoadjuvant chemoradiotherapy,but can't increase the survival of pathology complete respone and yPN + patients.

ObjectiveTo evaluate the value of modified early warning score (MEWS) in predicting mortality of critically ill patients admitted to emergency department.Methods A prospective cohort study was conducted. Clinical data of emergency patients admitted to resuscitation room of Peking Union Medical College Hospital from Feburary 13rd, 2014 to April 20th, 2014 were collected, and their MEWS were calculated based on medical records and their clinical outcomes was followed. Incidence of primary outcome (3-day mortality) and secondary outcome [all deaths and composite outcome of intensive care unit (ICU) transfer, cardio-pulmonary resuscitation, and death] were compared between MEWS positive (MEWS≥5) or negative (MEWS 0-4) patients, and multi-regression logistic analysis was done to look for the impact factors of primary outcome in these patients.Results 176 patients, among them 98 (55.68%) were male, were enrolled in the study. Their mean age was (56.86±21.46) years old. Mean MEWS was 4.30±2.74. There was 74 cases in MEWS positive group, and 102 in negative group. Primary endpoint occurred in 41 patients, and the 3-days mortality in MEWS positive group was significantly higher than that in MEWS negative group [37.84 (28/74) vs. 12.74% (13/102), odds ratio (OR) = 4.167, 95% confidence interval (95%CI) = 1.973-8.804,P< 0.001]. At the meantime, incidence of all death [54.05% (40/74) vs. 17.65% (18/102),OR = 5.490, 95%CI = 2.770-10.883,P< 0.001] and the incidence of ICU transfer, cardio-pulmonary resuscitation and death [64.86% (48/74) vs. 25.49% (26/102),OR = 5.396, 95%CI = 2.809-10.366,P< 0.001] were also significantly higher in MEWS positive group as compared with negative group. Multi-regression logistic showed abnormal mental status (OR = 3.606, 95%CI = 1.541-8.436,P = 0.003) but not MEWS≥5 (OR = 1.672, 95%CI = 0.622-4.494,P = 0.308)was the predictor of 3-day mortality in emergency admitted critically ill patients.Conclusions Although the incidence of severe adverse events is significantly increased in patients with MEWS≥5 compared with those with MEWS 0-4, MEWS≥5 cannot be an efficient predictor for 3-day mortality. Abnormal mental status shows some predictive value for early mortality in critically ill patients seen in emergency department.

Objective To investigate influence of amlodipine /atorvastatin on atherosclerosis in the elderly with hypertension and hyperlipidemia.Methods Totally 108 cases with hypertension and hyperlipidemia in our hospital were randomly divided into control group and observation group (n =54 each).The control group received conventional antihypertensive treatment such as diuretics,angiotensin-converting enzyme inhibitors,calcium antagonists; the observation group received amlodipine and atorvastatin combination tablet as add-on therapy to the above drugs for 6 months.The blood lipid level and carotid artery ultrasound detection results were observed and compared between the two groups after treatment.Results The levels of TC[(4.23 ± 0.79)mmol/L vs.( 5.32 ±1.23)mmol/L],TG[(1.53±0.35) mmol/L vs.(5.32± 1.23) mmol/L],LDL-C [(3.19 ± 0.59)mmol/L vs.(4.07±0.79)mmo1/L]were decreased,while HDL-C [(1.53±0.95)mmol/L vs.(1.32±0.83)mmol/L]were increased in observation group after treatment as compared to control group (all P ＜0.05).After carotid artery ultrasonography,the LN[( 1.61± 0.76) scores vs.( 2.24 ± 0.89) scores ] and IMT [(0.76 ± 0.22)mm vs.(0.98 ± 0.28)mm] levels were lower in observation group after treatment than in control group (P＜0.05).Conclusions Amlodipine/atorvastatin combination can reduce blood lipids and alleviate atherosclerosis.It is suitable for elderly patients with hypertension and hyperlipidemia.

Objective:investigate the effect of β-caryophyllene(BCP)on cerebral ischemia-reperfusion(CIR)injury in mice.Methods: Mice were subjected to CIR with or without BCP(62,124,248 mg/kg).At 24 h of reperfusion,ischemic degrees were determined according to neurologic dysfunction score and cerebral infarct volume.The protein expression of Toll-like receptor(TLR)4 was measured by Western blot.Nuclear factor κB(NF-κB)p65 were measured by immunohistochemistry and Western blot.IL-1β,tumor necrosis factor-α(TNF-α)and serum high-mobility group box 1(HMGB1)levels were measured by ELISA kit.Results: Compared to the CIR group,BCP(248 mg/kg)reduced the neurological score and cerebral infarct volume.BCP reduced neuronal death in mice brain subjected to cerebral I/R.In addition,BCP also inhibited the activation of NF-κB pathway and decreased increases in TLR4,HMGB1,TNF-α,IL-1β levels by CIR(P<0.01).Conclusion: BCP protects mice brain against CIR injury,its neuroprotective mechanisms may involves HMGB1/TLR4/NF-κB pathway.

Objective To investigate the expression of thyroid cancer-1 (TC1) and β-catenin in cervical carcinoma and precancerous lesions and their significance. Methods Immunohistochemical methods were used to examine the expression of TC1 and β-catenin in80 cervical squamous cell carcinoma (CSCC) tissues, 40 high-grade squamous intraepithelial lesions (HSIL), 40 low-grade squamous intraepithelial lesions (LSIL), and 30 normal cervical tissues. Results Although TC1 expression in CSCC was significantly higher than that in LSIL (P = 0.002) and normal cervical tissues (P ＜ 0.001), it was similar to that in HSIL (P = 0.576). TC1 expression was positively correlated with poor differentiation (P = 0.005) and advanced FIGO stage (P = 0.004) in CSCC. β-catenin expression in CSCC was significantly higher than that in LSIL (P ＜ 0.001) and normal cervical tissues (P ＜ 0.001), but was similar to that in HSIL (P = 0.907). The abnormal β-catenin expression was also correlated with poor differentiation (P = 0.025) and advanced FIGO stage (P = 0.001) in CSCC. TC1 expression was positively correlated with the abnormal β-catenin expression in CSCC (r = 0.294, P = 0.008) and cervical squamous intraepithelial lesions (r = 0.549, P ＜ 0.001). Conclusion TC1 and β-catenin expression in CSCC and HSIL was significantly higher than that in LSIL and normal cervical tissues. TC1 expression correlated with the abnormal β-catenin expression, and with poor differentiation and advanced FIGO stage of CSCC.
