RESUMEN
Objective:To compare the clinical efficacy of robot-assisted versus fluoroscopy-assisted sacroiliac screw internal fixation for posterior pelvic ring fractures.Methods:China National Knowledge Infrastructure (CNKI), Wanfang Data, Chinese Medical Journal Full-text Database, PubMed, Web of Science and ScienceDirect were searched for literature on robot-assisted versus fluoroscopy-assisted sacroiliac screw internal fixation for posterior pelvic ring fractures. The search time was from the establishment of each database to March 2023. Meta-analysis was performed on the included literature. The random-effects model was used when the heterogeneity between groups was large, and the fixed-effects model was used when the heterogeneity between groups was small.Results:A total of 15 studies were included in the meta-analysis, including 465 patients in the robot-assisted group and 396 patients in the fluoroscopy-assisted group. Meta-analysis showed that the number of fluoroscopies [ SMD=-3.12, 95% CI (-4.34, -1.89), P<0.001], the number of guide pin adjustments [ SMD=-3.75, 95% CI (-6.77, -0.72), P=0.015], intraoperative blood loss [ SMD=-0.83, 95% CI (-1.18, -0.49), P<0.001], and operative time [ SMD=-2.59, 95% CI (-4.11, -1.08), P<0.001] were smaller than those in the fluoroscopy-assisted group. The rate of excellent screw implantation [ OR=10.13, 95% CI (3.67,27.98), P<0.001] of the robot-assisted was larger than the fluoroscopy-assisted group. There was no significant difference in Majeed functional score [ SMD=0.28, 95% CI (-0.0003, 0.55), P=0.050] and fracture healing time [ SMD=-0.14, 95% CI (-0.46, 0.17), P=0.367] between the two groups. Conclusion:Robot-assisted percutaneous sacroiliac screw fixation for posterior pelvic ring fractures has the advantages of less fluoroscopy, less guide pin adjustment, less intraoperative blood loss, shorter operation time, and higher rate of excellent screw position. However, there is no difference in Majeed score and fracture healing time between robot-assisted percutaneous sacroiliac screw fixation and fluoroscopy-assisted percutaneous sacroiliac screw fixation.
RESUMEN
Acute coronary syndrome is a group of clinical syndromes based on the pathological basis of complete or incomplete occlusion of coronary artery caused by the rupture or invasion of coronary atherosclerotic plaque. It is a serious type of coronary heart disease. Acute coronary syndrome is clinically characterized by an acute onset of action and rapid pathological changes. Its prognosis differs greatly among patients with different categories of acute coronary syndrome and patients with the same category of acute coronary syndrome. Therefore, it is particularly important to reasonably use the risk score for risk stratification in patients with acute coronary syndrome, and select the optimized clinical treatment strategy according to the risk stratification, so as to reduce complications, reduce mortality and improve prognosis. This paper reviews the application of risk score in acute coronary syndrome.
RESUMEN
Objective To investigate the clinical efficacy of pemetrexed alone or combined with gefitinib in treatment of advanced non-small cell lung cancer (NSCLC) after epidermal growth factor receptortyrosine kinase inhibitor (EGFR-TKI) drug resistance.Methods The clinical data of 80 patients with advanced NSCLC after EGFR-TKI drug resistance from August 2014 to April 2018 were retrospectively analyzed.They were divided into two groups according to their treatment regimens:40 patients received pemetrexed alone (the control group) and 40 patients received pemetrexed combined with gefitinib (the observation group).The recent clinical efficacy,adverse reactions and the survival time of both groups were compared.The count data was compared by using x2 test or Fisher exact test.Kaplan-Meier method was used to make survival analysis and log-rank method was used to detect.Results The total effective rate of the observation group was higher than that of the control group [70.0％ (28/40) vs.32.5％ (13/40),x2 =11.257,P =0.001].There was no statistical difference in the adverse reactions [17.5％ (7/40) vs.20.0％ (8/40),x2 =0.082,P =0.775].The median progression-free survival time and median overall survival time of the observation group were longer than those of the control group (6.5 months vs.3.5 months,15.5 months vs.8.5 months,all P ＜ 0.01).Conclusion Pemetrexed combined with gefitinib has a recent favorable effect in advanced NSCLC after EGFR-TKI drug resistance,including low incidence of adverse reactions and prolonged survival time,which is worthy of further application.
RESUMEN
Objective To observe clinical effects of fleabane injection treating patients with unstable angina pectoris (UAP). Methods One hundred and sixty cases with UAP were randomly recruited into two groups: a control group (including 80 patients) received Asprin and Nitrate medication, and a treatment group(including 80 patients) received fleabane injection (20 mg/d, ivdrip) on the basis of the control group. Both groups were treated for two weeks. Results Compared with the control group, the treatment group showed significantly better clinical effects and electrocardiograph. Conclusion Fleabane injection has obvious clinical effects for treating patients with UAP.
RESUMEN
AIM: To investigate the damages of adrenal gland in rabbits infected with neisseria meningococci(MC).METHODS: 18 rabbits were injected with MC (1×1011 organism/kg, iv, model group, n=10) or normal saline (control group, n=8).TNF-α was detected in baseline (before challenged), 60 min and 120 min after injection. 120 min after injection, TNF-α immunochemical localization of adrenal gland was detected with ABC methods by electron microscopy. RESULTS: In model group, TNF-α positive cells were located in medulla and TNF-α released into simus of medulla. The medulla damages were appeared but gland cells of cortex was normal. No damages were showed in control group. TNF-α value of plasm was elevated at 60 min and 120 min after injection compared with control group. CONCLUSION: TNF-α was released into medulla and resulted in medulla damages after MC challenging. Adrenal cortex didnt damaged in early phase of MC septic shock.
RESUMEN
AIM: To study the effect of selectin on lung injury in rabbits with diabetic ketoacidosis(DKA). METHODS: 12 male New Zealand rabbits were divided into experimental group (DK groups, intravenous injection of streptozocin and alloxan monohydroate, n =6) and normal control group (received same dose of saline, n =6). After 72 hours, all the animals were killed and blood and lung tissue were collected. Blood gases, expressions of selectin-P and selectin-L were detected. RESULTS: The expression of selectin in DK group were higher than that in NS group. CONCLUSION: These results indicate that selectin expression may play an important role in lung injury during diabetic ketoacidosis.

AIM: To investigate the damages of adrenal gland in rabbits infected with neisseria meningococci(MC).METHODS: 18 rabbits were injected with MC (1?10 11 organism/kg, iv, model group, n=10 ) or normal saline (control group, n=8 ).TNF-? was detected in baseline (before challenged), 60 min and 120 min after injection. 120 min after injection, TNF-? immunochemical localization of adrenal gland was detected with ABC methods by electron microscopy. RESULTS: In model group, TNF-? positive cells were located in medulla and TNF-? released into simus of medulla. The medulla damages were appeared but gland cells of cortex was normal. No damages were showed in control group. TNF-? value of plasm was elevated at 60 min and 120 min after injection compared with control group. CONCLUSION: TNF-? was released into medulla and resulted in medulla damages after MC challenging. Adrenal cortex didnt damaged in early phase of MC septic shock. [
RESUMEN
Objective:To evaluate the levels of interleukin 18(IL-18) mRNA in peripheral blood mononuclear cells(PBMCs),livers and spleens in monkey endotoxic shock models.Methods:Cynomolgus monkeys were injected i.v. with lipopolysaccharide(LPS) (2.8 mg/kg) to prepare the endotoxic shock models. The mRNA levels of IL-18 in PBMCs,livers and spleens were tested by fluorescence semi-quantitative realtime reverse transcription(RT)-PCR and compared with that of TNF-? and IL-1?.Results:IL-18 mRNA expression in PBMCs remarkably increased at 120 min after LPS administration, so did in livers and in spleens at the same time. mRNA levels of TNF-? in PBMCs peaked at 60 min after LPS injection, and also increased markedly at 120 min in livers and spleens. IL-1? mRNA levels peaked at 60 min in PBMCs, and did not change so much in livers and in spleens.Conclusion:IL-18 mRNA expression in PBMCs can be up-regulated by LPS, but changed latterly than TNF-? and IL-1? in endotoxic shock cynomolgus monkeys. It is presumed that IL-18 can be produced by PBMCs and liver Kupffer cells(maybe splenic macrophages),and TNF-? is produced by a variety of cells, but IL-1? in bloodstream mainly come from PBMCs after LPS challenge.
RESUMEN
Bile collected from 28 cases with various hepatic or biliary diseases during operation was assayed for the ?-glucuronidase level. In Group I consisting of 14 patients with primary intrahepatic stone, the ?-glucuronidase level averaged 2250.67 u/dl, while in Group II consisting of 14 patieats with other hepatic diseases, it averaged only 463.99 u/dl(P = 0.01).The patients of both groups showed a declination of the enzyme level gostoperatively, but in Group I, the enzyme level raised with other hepatic diseases, he T-tube. The AMPS and MP contents of the bile .remarkable inhibitory effect on two substances exert their function in positive remarkable inhibitory effect on at pH4,6. It is believed that. ?-glucuronidase, Group 11 consisting the results of thisles in the reformation of biliary stones reformation biliaryWhen ?-glucuronidase level is lower than 200u/dl.Chinese traditional prescriptions with glycynrhizae liquid extract shows a remarkable inhibitory effect on this enzyme. In Chinese traditonal prescriptions, the drugs which can promote circulation and clear deposit are usually added. According to the results of this study, the authors suggest that the therapeutic effect of glycyrrhizae be emphasized.
