[Effect of anesthesia on cardiopulmonary complications in elderly patients with hip fracture].
Objective: To compare the effects of different types of anesthesia on postoperative cardiopulmonary complications in patients aged 80 years and above who received unilateral hip fracture surgery. Methods: The perioperative data of patients aged 80 and above who underwent unilateral hip fracture surgery in Peking Union Medical College Hospital from July 2009 to June 2014 were collected and grouped based on the types of anesthesia including general anesthesia, neuraxial anesthesia, and peripheral nerve block. Variables were analyzed including preoperative general conditions (age, sex, type of fracture, ASA physical status classification, preoperative cardiopulmonary complications), intraoperative conditions (type of surgical procedure, operative time, blood loss, total intraoperative fluid infusion), and postoperative conditions (length of hospital stay, postoperative hospital stay, ICU stay, postoperative newly developed cardiopulmonary complications, postoperative in-hospital death, hospitalization costs). ⋯ However, the cost of hospitalization was lower in neuraxial anesthesia group (45.6±21.4) thousand RMB and nerve block group (48.2±25.8) thousand RMB compared with general anesthesia group (56.3±21.6) thousand RMB, the difference was statistically significant(F=9.951, P=0.007). Conclusions: For elderly patients undergoing unilateral hip surgery, the type of anesthesia does not affect the incidence of postoperative cardiopulmonary complications. However, neuraxial anesthesia and nerve block may reduce the cost of hospitalization.

[Cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy to treat peritoneal carcinomatosis from gastric cancer: a clinical study of 110 patients].
Objective: To evaluate the safety and efficacy of cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (CRS+ HIPEC) in patients with peritoneal carcinomatosis from gastric cancer (GCPC). Methods: The clinical data and follow-up results of GCPC patients treated with CRS+ HIPEC were collected for a retrospective analysis. The primary endpoint was survival rate and the secondary endpoint was safety. ⋯ Multivariate Cox-analysis showed that completeness of cytoreduction, ascites, and postoperative adjuvant chemotherapy were independent factors of OS. Conclusion: CRS+ HIPEC improves survival for GCPC patients with normal preoperative tumor markers, low PCI, no ascites and synchronous PC. Stringent patient selection and complete CRS are two key factors for better survival.

[Cerebral grey matter changes of pre- and post-treatment in first-episode drug-naive adolescents schizophrenia].
Objective: To investigate the gray matter(GM) volume and the change of GM volume after antipsychotic treatment for 8 weeks in first-episode drug-naive adolescents with schizophrenia. Methods: T1-weighted brain MRIs were obtained on a 3T scanner in 35 controls and 35 subjects with adolescents schizophrenia who were admitted to the Second Affiliated Hospital of Xinxiang Medical College from April 2015 to June 2016 and not given antipsychotic medication, the schizophrenia patients received second scan after 8 weeks of antipsychotic treatment. ⋯ Results: GM volumes in the left frontal gyrus (MIN(x, y, z): -13.5, 36, 46.5), left superior parietal lobule (MIN(x, y, z): -52.5, -42, 52.5), left inferior parietal lobule (MIN(x, y, z): -31.5, -45, 69) and left central anterior (MIN(x, y, z): 9, 21, 61.5) were significantly smaller than those in the normal control group (t=-4.384 0, -4.556 2, -6.430 9, -4.313 9 respectively, P<0.001); after treatment for 8 weeks PANSS scores were significantly lower than those of baseline (P<0.001), however, there was no significant difference in regional GM volume between the pre-and post-treatment (P>0.05) and no significant correlation was found between GM volume and PANSS scores. Conclusion: There are local GM volume reductions in subjects with adolescents schizophrenia and these regions may be independent to mental symptoms of patients.

Comparative Study[Comparison of invasive and non-invasive blood pressure in critically ill patients].
Objective: To investigate the difference of invasive and noninvasive blood pressure in systolic, diastolic and mean blood pressure (SBP, DBP and MAP) levels in critically ill patients. Methods: A total of 197 critically ill patients were enrolled in the intensive care unit of Peking Union Medical College Hospital in this prospective observative study. There were 113 males and 84 females with a mean age of (59±17) years. ⋯ The mean bias and 95% confidence interval (CI) in SBP(invasive)-SBP(noninvasive), DBP(invasive)-DBP(noninvasive), MAP(invasive)-MAP(noninvasive) respectively was as following: SBP (14.5±11.9) mmHg (-8.8-37.8 mmHg); DBP (1.0±7.2) mmHg(-13.2-15.2 mmHg); MAP (10.5±8.3) mmHg (-5.9-26.8 mmHg). Moreover, there was a significant positive correlation between the bias of SBP(invasive)-SBP(noninvasive) and the value of SBP; when the SBP(invasive)≥143 mmHg was used to predict a value of bias≥20 mmHg, the sensitivity was 72.4% and specificity was 81.3%, and the area under the receiver operating characteristic curve was 0.808 (95% CI: 0.745-0.870). Conclusions: There is a good agreement between invasive and noninvasive blood pressure in critically ill patients, the bias of invasive-noninvasive blood pressure measurement is positively correlated to the value of blood pressure.

[Expression of stem cell markers CD44 and Lgr5 in colorectal cancer and its relationship with lymph node and liver metastasis].
Objective: To investigate the relationship between the expression of stem cell markers CD44 and Lgr5 and the clinicopathological features, lymph node and liver metastasis, and to analyse the value of both in evaluating the prognosis of colorectal cancer. Methods: A total of 90 cases of colorectal cancer, 20 cases of adjacent tissues, 30 cases of lymph node metastases, 28 cases of cancer nodules and 30 cases of liver metastasis of colorectal cancer were collected from Department of Pathology of the Second Hospital of Tianjin Medical University from January 2011 to June 2016. The expression of CD44 and Lgr5 protein was detected by immunohistochemistry, and the relationship between them and clinical pathological data, lymph node metastasis and liver metastasis were analyzed. ⋯ Cox proportional hazards regression model multivariate analysis showed that both positive expression of CD44 and Lgr5, lymph node metastasis, liver metastasis, and clinical stage were independent factors affecting the prognosis of patients with colorectal cancer(P=0.004, 0.044, 0.031, 0.008). Conclusions: The expression of CD44 and Lgr5 is related to the malignant biological behavior of colorectal cancer, and they are important factors in promoting local and distant metastases. Both positive expression of them have a hint of bad prognosis.
