RESUMEN
ABSTRACT Objective: The optimal target for blood glucose concentration in critically ill patients is unclear. We will perform a systematic review and meta-analysis with aggregated and individual patient data from randomized controlled trials, comparing intensive glucose control with liberal glucose control in critically ill adults. Data sources: MEDLINE®, Embase, the Cochrane Central Register of Clinical Trials, and clinical trials registries (World Health Organization, clinical trials.gov). The authors of eligible trials will be invited to provide individual patient data. Published trial-level data from eligible trials that are not at high risk of bias will be included in an aggregated data meta-analysis if individual patient data are not available. Methods: Inclusion criteria: randomized controlled trials that recruited adult patients, targeting a blood glucose of ≤ 120mg/dL (≤ 6.6mmol/L) compared to a higher blood glucose concentration target using intravenous insulin in both groups. Excluded studies: those with an upper limit blood glucose target in the intervention group of > 120mg/dL (> 6.6mmol/L), or where intensive glucose control was only performed in the intraoperative period, and those where loss to follow-up exceeded 10% by hospital discharge. Primary endpoint: In-hospital mortality during index hospital admission. Secondary endpoints: mortality and survival at other timepoints, duration of invasive mechanical ventilation, vasoactive agents, and renal replacement therapy. A random effect Bayesian meta-analysis and hierarchical Bayesian models for individual patient data will be used. Discussion: This systematic review with aggregate and individual patient data will address the clinical question, 'what is the best blood glucose target for critically ill patients overall?'

RESUMEN
This report introduces a young adult who has been in bed for more than ten years with end-stage hemophilic arthropathy. He didn't have access to factor VIII (FVIII) in the early stage of hemophilia due to the high costs of clotting replacement therapy. As a result, he is experiencing some difficulties, such as joint contracture, muscular atrophy, severe pain, and poor function of cardiopulmonary. He came to visit us for a comprehensive rehabilitation program, and, finally, he achieved the basic goal of self-care in daily life.

OBJECTIVE: To explore the blood circulation activating effect and mechanism of Sanqi (Radix Notoginseng) in vivo, using a venous thromboembolism (VTE) rat model. METHODS: We established the VTE rat model, and then intervened with low molecular weight heparin (LMWH), as well as low, medium and high doses of Sanqi (Radix Notoginseng), to observe the blood circulation activating effect of Sanqi (Radix Notoginseng) on VTE rats. RESULTS: After the treatment with high concentrations of Sanqi (Radix Notoginseng), the pulmonary thromboembolism was alleviated, and the lower limb thrombosis was markedly improved. Moreover, the expression quantities of plasma activated partial thromboplastin time, prothrombin time and D-dimer, as well as endothelin, von Willebrand factor, and plasminogen activator inhibitor-1 in thrombosis segment tissues were markedly down-regulated; while those of nitric oxide and tissue-type plasminogen activator were up-regulated. After low and medium concentration Sanqi (Radix Notoginseng) treatment, no obvious improvement was observed in each index. Moreover, the high concentration Sanqi (Radix Notoginseng) showed comparable efficacy to the positive drug LMWH. CONCLUSION: This data suggests that high concentration of Sanqi (Radix Notoginseng) is effective in preventing and treating VTE.

OBJECTIVE: To explore the preventive effect of applying hot compress with Chinese herbal salt packets (CHSP) to puncture vessels under aseptic conditions during peripherally inserted central catheter (PICC) on postoperative phlebitis. METHODS: A total of 720 hospitalized patients undergoing first PICC were assigned to treatment and control groups (360 cases each group) according to a random number table. The control group received conventional catheterization and nursing care. The treatment group was first given hot compress with CHSP (which consisted of honeysuckle 30 g, Semen brassicae 30 g, Salvia miltiorrhiza 30 g, Angelica dahurica 30 g, Semen raphani 30 g, Evodia rutaecarpa 30 g, and coarse salt 20 g) on the punctured vessel under aseptic conditions for 5-10 min before conventional catheterization. The main efficacy indices were the vessel diameters before and during catheterization and the success rate of a single catheter, and the secondary efficacy indiex was the incidence of superficial phlebitis within 1 week after catheterization. RESULTS: The vessel diameter during catheterization of the treatment group was remarkably increased compared with the control group [(7.96±0.42) mm vs. (4.39±0.54) mm, P<0.01]. The success rate of the single catheter of the treatment group was significantly higher than that of the control group [94.00% (329/350) vs. 73.72% (244/329), P<0.01]. The incidence of superficial phlebitis within 1 week after catheterization in the treatment group was lower than that in the control group (P=0.007). There was no adverse event with CHSP. CONCLUSION: Hot compress with CHSP during PICC is applicable as it can effectively improve the success rate of a single catheter and reduce the incidence of superficial phlebitis after catheterization (Trial registration No. ChiCTR-ONC-17010498).

Sepsis results in high morbidity and mortality. Immunomodulation strategies could be an adjunctive therapy to treat sepsis. Acupuncture has also been used widely for many years in China to treat sepsis. However, the underlying mechanisms are not well-defined. We demonstrated here that EA preconditioning at ST36 obviously ameliorated CLP-induced intestinal injury and high permeability and reduced the mortality of CLP-induced sepsis rats. Moreover, electroacupuncture (EA) pretreatment exerted protective effects on intestinal mucosal immune barrier by increasing the concentration of sIgA and the percentage of CD3+, γ/δ, and CD4+ T cells and the ratio of CD4+/CD8+ T cells. Although EA at ST36 treatments immediately after closing the abdomen in the CLP procedure with low-frequency or high-frequency could not reduce the mortality of CLP-induced sepsis in rats, these EA treatments could also significantly improve intestinal injury index in rats with sepsis and obviously protected intestinal mucosal immune barrier. In conclusion, our findings demonstrated that EA at ST36 could improve intestinal mucosal immune barrier in sepsis induced by CLP, while the precise mechanism underlying the effects needs to be further elucidated.
RESUMEN
PURPOSE: The effects of Shenfu injection on protecting the intestinal mucosal barrier were investigated in rats with sepsis. METHODS: Severe sepsis was established by cecal ligation and puncture (CLP) in 30 healthy Sprague-Dawley rats. Twelve rats that received sham surgery received 10 mL/kg of normal saline. Rats with CLP were randomized to receive 10 mL/kg of normal saline (n = 12) and 5 mL/kg Shenfu (n = 12), and 10 received 10 mL/kg Shenfu injection (n = 12) by tail intravenous injection. Rats were killed after 8 hours. Serum levels of tumor necrosis factor α and interleukin-10, and ileal malondialdehyde and superoxide dismutase activity were measured by enzyme-linked immunosorbent assay. Ileum tissue structures and pathological score were observed by microscopy. Ileal mucosal epithelial cell apoptosis index was calculated by TUNEL assay. Ileal proapoptotic protein Bax, antiapoptotic protein Bcl-2, and tight junction transmembrane protein occludin were measured by immunohistochemistry and immunoblot. RESULTS: The level of tumor necrosis factor α, the ileal malondialdehyde level, ileum pathological score, apoptosis index of ileal mucosal epithelial cells, and Bax protein level were significantly higher, and serum level of interleukin-10, the ileal superoxide dismutase activity, Bcl-2 protein level, Bcl-2/Bax ratio, and occludin protein level were significantly lower in the CLP group than in the sham group (P < .01 or P < .05). Both low- and high-dose Shenfu significantly ameliorated these changes (P < .01 or P < .05), but high-dose injection achieved more significant improvements than did the low-dose injection (P < .01 or P < .05). CONCLUSIONS: Shenfu injection might ameliorate the mucosal barrier function in a model of sepsis in rats in a dose-dependent manner.

BACKGROUND: Acute pulmonary embolism (APE) is a disorder involving the pulmonary circulation resulting from a blockage of the pulmonary artery. The present study aimed to investigate the effects of aspirin on the nuclear factor-κB (NF-κB) activity in a rat model of APE. METHODS: A total of 108 healthy male Sprague-Dawley rats were randomly assigned into six groups (n=18 rats per group): control group, sham operation group, APE model group, and low-, medium- and high-dose aspirin groups. Six, 24, and 72 hours after the induction of APE, rats in the low-, medium- and high-dose aspirin groups were given aspirin at a respective daily dose of 150, 300, and 600 mg/kg by gavage for three consecutive days. Rats in the other groups were treated with equal volumes of normal saline. Six rats in each group were anesthetized with 10% chloral hydrate solution at each time point, and then the lung tissues were collected and analyzed using immunohistochemical staining. RESULTS: Positive immunohistochemical staining was present in the bronchial epithelial cells, alveolar cells, macrophages, and surrounding bronchial smooth muscle cells. When compared with the APE model group, the number of positive cells was significantly lower in the other groups at each time point (P<0.001). Statistically significant differences were also observed among the aspirin-treated groups at 6 hours (P<0.05, P<0.001). Compared with the APE model group, NF-κB protein expression was reduced in the other groups at each time point (P<0.05, P<0.001). Rats from the APE model group had thrombosis, damaged alveolar walls, and pulmonary hemorrhage, along with different degrees of inflammatory cellular infiltration at each time point. However, pathological changes such as pulmonary hemorrhage and infiltration of inflammatory cells were attenuated after the aspirin treatment. CONCLUSION: Aspirin can significantly inhibit NF-κB activity in the lung of rats with APE in a dose-dependent manner, and can alleviate lung injury after APE.
RESUMEN
OBJECTIVE: To observe the efficacy of electroacupuncture on sepsis and explore its mechanism. METHODS: Fifty cases were randomized into an observation group (26 cases) and a control group (24 cases). The therapeutic programs of anti-infection, anti-shock, respiratory support and nutritional support were provided, but the drugs that might affect gastrointestinal motility were not prescribed in two groups. In the observation group, on the basic treatment as above, electroacupuncture was applied to Zusanli (ST 36), Tianshu (ST 25), Shangjuxu (ST 37), Xiajuxu (ST 39). The excretion ratio of lactulose to mannitol (L/M) in urine and serum D-lactic acid level were detected before and after treatment, as well as the time of target feeding of the patients in two groups. The efficacy was compared between two groups. RESULTS: After treatment for 3 days, L/M was (0.083 +/- 0.020) and serum D-lactic acid was (0.155 +/- 0.196) mmol/L in the observation group, which were apparently reduced as compared with (0.123 +/- 0.034) and (0.193 +/- 0.377) mmol/L in the control group respectively (both P < 0.05). The time of target feeding was (93.69 +/- 27.58) h in the observation group, which was shortened apparently than (118.17 +/- 40.28) h in the control group (P < 0.05). The total effective rate was 80.8% (21/26) in the observation group, which was better than 54.2% (13/24) in the control group (P < 0.05). CONCLUSION: Conventional treatment combined with electroacupuncture can improve intestinal permeability in sepsis patients, recover intestinal function as quickly as possible to achieve target feeding.

OBJECTIVE: To explore the intervention of aspirin and the changes of CX3CL1 and its receptor CX3CR1 in a rat model of acute pulmonary embolism (APE). METHODS: The autologous blood clot method was employed to establish the animal model of APE. A total of 64 rats were randomly divided into 4 groups: normal group (control), sham operation group (sham), model group (model) and aspirin group (aspirin). The profiles of pathology and tissue immunohistochemistry of CX3CL1 and CX3CR1 were compared at 4 h versus 72 h post-embolization. RESULTS: At 4 h and 72 h post-embolism, hematoxylin and eosin staining of lung tissue showed a high degree of expansion of alveolar wall vessels and congestion. Furthermore, several rats had hemorrhagic infarction under light microscope. After the dosing of aspirin, hyperemia of lung tissue and the number of rats with infarction significantly decreased. Immunohistochemistry: CX3CL1 was predominantly expressed in cytoplasm and membrane while CX3CR1 in cytoplasm and nuclear membrane. Both showed strongly positive expression in the model group (++++) and slightly positive expression in the aspirin group (+). At 4 h and 72 h post-embolization, the CX3CL1 and CX3CR1-positive cell counts of the control, sham and aspirin groups were significantly less than those of the model group (P < 0.05). CONCLUSION: Aspirin may improve the pathology and inhibit the expression of CX3CL1 and CX3CR1 in APE lung.

Objective. To explore the intervention methods of the patients with dysuria after performing the procedure for prolapse and hemorrhoids (PPH). Methods. 100 cases with hemorrhoids were randomly divided into experimental and control groups. The control group received routine nursing care. As comparison, the experimental group, on the basis of conventional care, was treated with moxa roll moxibustion 1 hour after the operation for 30 minutes. The autonomous urination within 1 h, 2 h, 4 h, 6 h, and 8 h after operation and the catheterization rate 8 h after operation of two groups of patients were observed. Results. The median time of autonomous urination of control group (8 h) was significantly greater than that of the experimental group (6 h) (P < 0.001). Cox regression analysis showed that the moxibustion therapy was positively correlated with automatic micturition in the patients after PPH. The probability of automatic micturition in the experimental group was 2.032 times that in the control group (RR = 2.032, 95% CI: 1.278~3.230). The catheterization rate of control group (38%) was significantly higher than that of the experimental group (10%) (P < 0.001). Conclusion. The Guanyuan acupoint moxibustion can prevent dysuria after PPH and reduce the urethral catheterization.
RESUMEN
OBJECTIVE: To investigate the effects of sodium copper chlorophyllin (SCC) on the proliferation, differentiation and immunomodulatory function of mesenchymal stem cells (MSCs) from mice with aplastic anemia. METHODS: A mouse model of aplastic anemia was established by exposure of BALB/c mice to sublethal doses of 5.0 Gy Co60 γ radiation, followed by transplantation of 2×10(6) lymph node cells from DBA/2 donor mice within 4 h after radiation. Aplastic anemic BALB/c mice were randomly divided into six groups: the treated groups, which received 25, 50, or 100 mg/kg/day SCC, respectively; a positive control group treated with cyclosporine A (CsA); and an untreated model control group (model group); while, the non-irradiated mice as the normal control group. SCC or CsA were administered by gastrogavage for 20 days, starting on day 4 after irradiation. Peripheral blood cells were counted and colony-forming fibroblasts (CFU-F) in the bone marrow were assayed. The ability of MSCs to form calcium nodes after culture in osteoinductive medium was also observed. The immunosuppressive effect of MSCs on T lymphocytes was analyzed by enzyme-linked immunosorbent assay and flow cytometry, to evaluate the efficacy of SCC in mice with aplastic anemia. RESULTS: Peripheral blood white cell and platelet counts were increased by medium and high SCC doses, compared with the untreated control. CFU-Fs were also increased compared with the untreated control, and the numbers of calcium nodes in MSCs in osteoinductive medium were elevated in response to SCC treatment. The percentage of Forkhead box protein 3 (FOXP3(+)) T cells was increased in T cell-MSC cocultures, and the cytokine transforming growth factor ß1 was up-regulated in SCC-treated groups. CONCLUSION: The results of this study suggest that SCC not only promotes the proliferation and differentiation of MSCs, but also improves their immunoregulatory capacity in mice with aplastic anemia.

OBJECTIVE: To observe the effect of intensive insulin therapy on improving the condition of critically ill patients. METHODS: A prospective, randomized, controlled study involving adults receiving mechanical ventilation was performed. On admission, critically ill patients were randomly assigned to receive intensive insulin therapy (infusion of insulin only if the blood glucose level exceeded 6.1 mmol/L and maintenance of blood glucose at a level 4.4-6.1 mmol/L, IT group) and conventional treatment (infusion of insulin only if the blood glucose level exceeded 11.9 mmol/L and maintenance of blood glucose at a level 10.0-11.1 mmol/L, CT group). The blood glucose was detected every 4 hours. The days of stay in the intensive care unit (ICU), time of the ventilatory support needed, the time for retention of tracheal intubation, the morning blood glucose level (6 am), the intake of nonprotein calories per day, the dosage of required insulin per day,therapeutic intervention scoring system-28 (TISS-28) score,human leukocyte antigen (locus) DR (HLA-DR), CD4+/CD8+, the mortality rate,acute renal failure (serum creatine >221 micromol/L), bilirubinemia (total bilirubin >34.2 micromol/L),the number of patients who received red-cell transfusions,fever (temperature in mouth >38.5 centigrade) and the rate of hypoglycemia were determined and registered. RESULTS: In a total of 116 patients enrolled, intensive insulin therapy reduced mortality rate (44.83 % with conventional treatment, compared with 12.07 % with intensive insulin therapy,P< 0.01). Intensive insulin therapy reduced the days of stay in ICU, TISS-28 score per day, time of the ventilatory support needed, time for retention of tracheal intubation, mean morning blood glucose levels (6 am) compared with those in CT group (P<0.05 or P<0.01), and patients receiving intensive insulin therapy were less likely to require intensive care. Intensive insulin therapy also raised consumption of insulin per day, HLA-DR and CD4+/CD8+ obviously (P<0.05 or P<0.01). Compare with the morbidity between two groups, the incidence of fever due to infection, acute renal failure and red-cell transfusions were higher in CT group (all P<0.01). CONCLUSION: Intensive insulin therapy maintaining blood glucose at a level 4.4-6.1 mmol/L reduces mortality rate among critically ill patients.
