  • Intensive Glucose Control Compared with Standard Therapy in Type 2 Diabetes: A Systemic Review

    Objectives To systemically review and investigate the efficacy of intensive glucose control in Type 2 diabetes mellitus. Methods Database searches of MEDLINE, EMBASE, Cochrane Controlled Trials Register, VIP Database, CNKI, and CBM disc (from the date of establishment of the databases to June 2009) were conducted. Additional studies were retrieved via references of articles and direct contact with the authors to retrieve relevant data. Prospective, randomized controlled trials of intensive glucose control compared with standard therapy in diabetic patients were selected. We accessed the quality of included trials and extracted the relevant data. Statistical analysis was performed using The Cochrane Collaboration’s software RevMan 5.0. Results Eight trials with a total of 37 004 participants were included. The Meta-analysis showed: intensive glucose therapy was associated with a significant 9% reduction in the odds of cardiovascular events [OR=0.91, 95%CI (0.85, 0.98), P=0.007], and a 26% reduction in the microvascular events [OR=0.74, 95%CI (0.60, 0.91), P=0.005]. For the peripheral vascular events, no statistical difference was found between intensive therapy and standard therapy [OR=0.94, 95%CI (0.83, 1.07), P=0.35]. No statistical difference could be found in total mortality [OR=1.00, 95%CI (0.92, 1.08), P=0.98] and cardiovascular mortality [OR=1.03, 95%CI (0.83, 1.28), P=0.77]. Intensive therapy could increase more than 1.1-fold odds of hypoglycemia compared with standard-therapy [OR=2.12, 95%CI (1.24, 3.60), P=0.006]. Conclusions Findings from this meta-analysis suggest that intensive glucose control significantly reduces the risk of cardiovascular events and microvascular events, and increases the risk of hypoglycemia, while no prominent difference is found in mortality.

  • The clinical significance of GSDMD and caspase-1 expressions in the invasive ductal breast carcinoma

    Objective To study the clinical significance of gasdermin-D(GSDMD) and caspase-1 expressions in the invasive ductal breast carcinoma. Methods Seventy-seven female patients with invasive ductal carcinoma of breast performed radical resection in the 904th Hospital of Joint Logistic Support Force of PLA from January 2015 to June 2016 were selected as the research object. The expressions of GSDMD and caspase-1 protein in cancer tissues and 20 adjacent tissues were detected by immunohistochemistry, and their correlation with clinicopathological features was analyzed. Kaplan-Meier analysis was used to draw the survival curve, and log-rank test was used for univariate survival analysis, and Cox proportional hazards regression analysis of prognostic factors in patients with breast invasive ductal carcinoma. Results The proportion of high expression of GSDMD and caspase-1 protein in adjacent tissues were significantly higher than those in breast cancer tissues (P<0.05). Univariate analysis results showed that the survival time of patients with invasive ductal carcinoma of breast were correlated with lymphatic metastasis, TNM staging, and the expression status of progesterone receptor, GSDMD, caspase-1 and Ki-67 (P<0.05). Multivariate analysis results showed that the low expression of GSDMD protein [HR=4.096, 95%CI (1.102, 15.216), P<0.05] and low expression of caspase-1 protein [HR=3.945, 95%CI (1.062, 14.652), P<0.05] were the independent risk factor that affect the survival rate of patients with invasive ductal carcinoma of breast. Conclusion The low expression of GSDMD and caspase-1 protein in invasive ductal carcinoma of breast are independent risk factors for postoperative survival.

  • Human Recombinant Activated Protein C for Severe Sepsis: A Meta-Analysis

    Objective To systemically review the effectiveness and safety of human recombinant activated protein C (rhAPC) for severe sepsis. Methods Such databases as MEDLINE, EMbase, The Cochrane Library, VIP, CNKI and CBM were electronically searched for comprehensively collecting randomized controlled trials (RCTs) on the effectiveness and safety of human recombinant activated protein C (rhAPC) for severe sepsis from inception to July 2012. References of included studies were also retrieved. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.0 software. Results Totally, five RCTs involving 6 307 patients were included. The results of meta-analysis showed that, no significant difference was found in 28-day mortality (RR=1.00, 95%CI 0.84 to 1.19, P=1.00) and 90-day mortality (RR=1.00, 95%CI 0.87 to 1.14, P=0.96) between the rhAPC group and the placebo group. The results of subgroup analysis showed that, the two groups were similar in the 28-day mortality of patients with different Acute Physiology and Chronic Health Evaluation II (APACHE II) scores (APACHE II scorelt;25: RR=1.06, 95%CI 0.93 to 1.21, P=0.37; APACHE II score≥25: RR=0.93, 95%CI 0.69 to 1.24, P=0.60), and in the 28-day mortality by protein C deficiency class (APC deficiencylt;80%: RR=0.96, 95%CI 0.56 to 1.65, P=0.89; APC deficiencygt;80%: RR=0.61, 95%CI 0.34 to 1.08, P=0.09). Besides, bleeding risk in the rhAPC group was 1.62 fold more than that in the placebo group (RR=1.62, 95%CI 1.17 to 2.23, P=0.004). No significant difference was found in the incidence of adverse reaction (RR=1.04, 95%CI 0.92 to 1.18, P=0.53). Conclusion Current evidence suggests that, rhAPC could not improve the prognosis of patients with severe sepsis, but it significantly increases bleeding risk.

  • Hyperoxia Management During Deep Hypothermia for Cerebral Protection in a Circulatory Arrest Rabbit Model

    Abstract: Objective To investigate the cerebral protective effects of hyperoxia management during deep hypothermia circulatory arrest(DHCA) rabbit by the blood gas indexes, superoxide dismutase( SOD) activity and malondialdehyde (MDA) levels of brain, and ratio of water to brain. Methods A DHCA and antegrade selective cerebral perfusion (ASCP) rabbit model was established. Twenty-four 11-13 week-old male New Zealand rabbits( weighing 2.7 to 3.4 kg) were assigned to three groups with a random number table: a sham operation group (Sham group), an ASCP group (S group), and an ASCP + hyperoxia management group (SH group). There were eight rabbits in each group. We recorded the intraoperative values for arterial oxygen pressure (PaO2), arterial oxygen saturation (SaO2), jugular venous oxygen pressure(PjvO2), jugular venous oxygen saturation( SjvO2) and blood lactate level. The brain SOD activity, MDA levels, and ratio of water to brain were measured after the operation. Results Before initiating circulatory arrest, before initiating reperfusion and five minutes of reperfusion, levels of PaO2 , PjvO2 , and SjvO2 in the SH group were significantly higher than those of the S group and Sham group. SOD activity in the SH group was not significantly different from that of the S group[(213.53±33.52) U/mg. prot vs. (193.02±27.67) U/mg. prot] and Sham group[(213.53±33.52) U/mg. prot vs.(244.38±35.02)U/mg. prot], but the SOD activity in the S group was lower than that in the Sham group( P < 0.05). MDA levels in the SH group were lower than that in the S group[(1.42±0.30) nmol/mg. prot vs. (2.37±0.55) nmol/mg. prot, P < 0.05]. Conclusion Our data show that hyperoxia management during DHCA+ASCP improves rabbits’PjvO2 and SjvO2, maintains brain SOD activity, and decreases brain MDA levels, demonstrating the neuroprotective effects of hyperoxia mangagement.

  • RESEARCH PROGRESS IN SURFACE MODIFICATION OF ORTHOPAEDIC IMPLANTS VIA EXTRACELLULAR MATRIX COMPONENTS

    Objective To review the research progress of promoting the bone formation at early stage by components of the extracellular matrix (ECM). Methods Recent literature concerning the influence of these components on new bone formation and bone/implant contact was extensively reviewed and summarized. Results Coating of titanium or hydroxyapatite implants with organic components of the ECM (such as collagen type I, chondroitin sulfate, and Arg-Gly-Asp peptide) offers great potential to improve new bone formation and enhance bone/implant contact, which in turn will shorten recovery time and improve implant stability. Conclusion The increasing knowledge about the role of the ECM for recruitment, proliferation, differentiation of cells, and regeneration of tissue will eventually deal to the creating of an artificial ECM on the implant that could allow a defined adjustment of the required properties to support the healing process.

  • Etiological study on optic neuritis

    Objective To investigate the etiological distribution of the patients with optic neuritis in China and compare the results with those in western countries. Methods Ophthalmological and neurological detailed clinical and laboratorial examinations were performed on 204 patients with primarily diagnosed optic neuritis (ON). We determined the etiologies using international accepted diagnostic criteria. Results Among 113 patrents with ON, 83(73.5%) were considered as with idiopathic demyelinating optic neuritis ( IDON). Sinusitis was common in these patients but was considered to be the probable cause of ON only in 4. Tuberculo-meningitis caused ON was found in 2 cases and syphilitic ON in 1. The causes of 23 cases (20.4%) were unknown. Conclusions Idiopathic demyelinating ON is the most common pathogeny of ON. Despite of some minor differences of causes and prognosis, the etiology of presumed ON in our population is similar to that reported in western countries. (Chin J Ocul Fundus Dis,2006,22:367-369)

  • Dopamine versus Norepinephrine for Septic Shock: A Systemic Review

    Objective To systemically review the efficacy and safety of dopamine versus norepinephrine in patients with septic shock. Methods Database searches of MEDLINE, EMbase, Cochrane Controlled Trials Register, VIP, CNKI, and CBM (from the date of database establishment to June 2011) were conducted. Additional studies for collecting relevant data were retrieved via both references of articles and direct contact with authors. Prospectively, randomized controlled trials (RCTs) of dopamine compared with norepinephrine therapy in septic shock patients were selected. The quality of included trials was assessed and relevant data were extracted. Then statistical analysis was performed using RevMan 5.1. Results Nine trials with 3 179 participants were included. The results of meta-analysis showed: compared with norepinephrine, dopamine was associated with a significant 12% elevation in the risk ratio of in-hospital death events of septic shock patients (RR=1.12, 95%CI 1.04 to 1.21, P=0.002). The risk of arrhythmias in dopamine group was 2.63-fold than that in norepinephrine group (RR=2.63, 95%CI 1.51 to 4.55, P=0.000 6). The cardiac index of septic patients in dopamine group was higher than that in norepinephrine group (MD=0.42, 95%CI 0.21 to 0.63, Plt;0.000 1). No significant difference could be found in the heart rate (MD=17.05, 95%CI –0.71 to 34.81, P=0.06) and mean arterial pressure (MD= –0.87, 95%CI –24.97 to 7.62, P=0.30). Conclusion Findings from this meta-analysis suggest that compared with dopamine, norepinephrine significantly reduces both 28-day mortality of septic shock patients and incidence rate of arrhythmias. Norepinephrine is better than dopamine in aspects of efficacy and safety.

  • Clinical efficacy of systemic rehabilitation training on sports function recovery of sports fans after anterior cruciate ligament reconstruction

    Objective To explore the clinical significance of systemic rehabilitation training on knee functional recovery after anterior cruciate ligament (ACL) reconstruction. Methods Patients who underwent arthroscopic knee ACL reconstruction and met the inclusion criteria were included from January 2015 to October 2016. A 4-phase, 16-week systemic rehabilitation training was given individually according to surgical conditions, sports and other factors. Visual Analogue Scale (VAS), knee range of motion (ROM), knee circumference, and 10-meter walking time were measured before surgery, and 3, 6, and 12 months after surgery. At the same time, the function and stability of the knee joint were graded by Lysholm score, Holden walking score, International Knee Documentation Committee (IKDC) score, and KT-1000 test. The postoperative one-year scores were compared with the other side, and the patient satisfaction was evaluated one year after surgery. Results All patients were followed up for at least one year. The VAS pain score, ROM, knee circumference, 10-meter walking time, Lysholm score, Holden score, IKDC score, and KT-1000 of all patients were significantly better than their preoperative levels (P<0.05), and there was no significant difference in joint function from the contralateral side (P>0.05). No serious complications such as infection occurred. Conclusion Systemic rehabilitation exercises can help patients with well-restored knee joint function after ACL reconstruction.
