OBJECTIVE To explore the method for sterilizing hands which is effective,convenient and without stimulation for medical personnel.METHODS A total of 150 nurses on duty were divided into three groups randomly.In the test groups 1and 2,towels with 0.2% peracetic acid and BANENG disinfectant fluid were used separately,but in the control group only soap with flowing water was used for hands sterilization.RESULTS The rate of bacterial removal was 98.82%,72.63% and 68.64%,respectively,among the 3 groups.The efficacy of BANENG disinfectant fluid was similar to 0.2% peracetic acid.Both of them showed significant differences compared with control group.CONCLUSIONS Both 0.2% Peracetic acid and BANENG disinfectant fluid have better disinfection efficacy,and BANENG disinfectant fluid is more easier in use.

Objective To study the effects of hypotensive resuscitation on microvascular perfusion in a clinically relevant model of uncontrolled hemorrhagic shock in pregnancy. Methods Thirty New Zealand white rabbits at 15 -25 days, pregnanal age were randomly divided into three groups; Group normal saline traditional aggressive resuscitation ( NS), traditional aggressive resuscitation in the prehospital phase with a large quantity of normal saline and Ringer's solution to maintain mean arterial pressure (MAP) at the approximately 80 mm Hg ( 1 mm Hg = 0.133 kPa) level: Group normal saline hypotensive resuscitation (NH) and group hypertonic hyperosmotic hypotension resuscitation (HHH), hypotensive resuscitation in the prehospital phase with a bolus dose of 4 ml/kg normal saline or hypertonic hydroxyl ethyl starch (10% hydroxyl ethyl starch + 7.5% NaCl), followed by Ringer's solution to maintain MAP at 60 mm Hg.Production pregnant rabbit model with hemorrhagic shock. The experiment consisted of four phases:basic phase (0 miniutes), shock phase (0- 30 miniutes), prehospital phase (30- 90 miniutes) and hospital phase (90- 180 miniutes). Measurements: (1) arteriole and venule diameter were continuously monitored by microcirculatory detecting instrument; (2) functional capillary density (FCD) of each phase was expressed by the percentage of opening capillaries segments relative to basic phase; (3) blood pH, BE PCO2, PO2 in pregnant rabbits were determined with a Medica Easy Blood Gas Analyzer. Results ( 1 )There were no significant differences among three groups in arteriole and venule diameter at baseline ( P ＞0.05 ). After hemorrhagic shock arteriole diameter were NS ( 50.8 ± 5.6) μm, NH (47.6 ± 3.7 ) μm, HHH (51.3 ±2.4)μm, respectively, with no significant differences between groups(P ＞0.05). At the end of prehospital resuscitation phase and hospital resuscitation phase, significant differences were found in arteriole diameter in group NS(52.8 ± 4.9, 56.0 ± 3.8 )μm, NH (61.3 ± 2.9, 65.4 ± 3.2 )μm and HHH group (67.0 ± 4.1,74.1 ± 4.8 )μm ( P ＜ 0.05 ); after hemorrhagic shock venule diameter were NS(79.6 ± 7.0)μm, NH (75.3 ±5.3)μm and HHH(76.2 ±5.8)μm, respectively, with no significant differences between groups(P ＞0.05 ). At the end of prehospital resuscitation phase and hospital resuscitation phase,venule diameter were NS(81.1 ± 6.7, 84.4 ±6.0)μm, NH(82.8 ± 3.3, 85.4 ±4.3) μm and HHH (86.9 ± 5.8, 89.4 ± 6.8)μm, respectively, with no significant differences between groups ( P ＞ 0.05 ). (2) The values of FCD in every groups were all 100%. After hemorrhagic shock FCD were NS(39.8 ±6.8)%, NH (43.9 ±4.0)%, HHH(44.0 ± 4.8)%, respectively, with no significant differences between groups(P ＞0.05); at the end of prehospital resuscitation phase and hospital resuscitation phase, FCD were NS(54.5 ±7.3,59.7 ±4.8)%,NH(63.1 ±5.8,70.3 ±5.6)% and HHH (80.5 ±6.9, 91.7 ±4.7)%,respectively, with significant differences between groups( P ＜ 0.05 ). (3) Blood gas parameter: the values of blood pH, BE, PO2, PCO2 in pregnant rabbits in all groups were within normal bounds at basic phase. Shock phase induced typical hyperventilation in all groups, with increase of arterial PO2 and decrease of PCO2; at the end of hospital resuscitation phase, there were no significant difference among the three groups in the values of blood PCO2 ( P ＞ 0.05 ); the values of blood PO2 at the hospital resuscitation phase were significantly lower in NS groups than corresponding values in the other groups (P ＜ 0.05 ). After hemorrhagic shock there was significant metabolic acidosis as shown by decrease of pH, BE; at prehospital resucitation phase, pH, BE values tended to increase in all the groups but not reach to base period. At the end of hospital resucitation phase. The pH, BE value was significantly higher in NS group than those in the other two groups( P ＜ 0.05 ) . (4) Median survival time in NS (2.1 ± 0.2) days group was significantly shorter than NH(3.0 ±0.3) days and HHH(3.6 ± 0.3) days group( P ＜ 0.05). FCD at the end of the hospital resuscitation were significantly related with survival time ( r = 0.655, P = 0.000 ). Conclusion Compared with traditional aggressive fluid resuscitation, hypotensive resuscitation reduce constriction of arterial and venule diameter, increase FCD, alleviate metabolic acidosis and improve long-term survival Hypertonic hydroxyl ethyl starch resuscitation ameliorate microcirculation without improving survival rate.

Drug addiction is a chronic and relapsing brain disease, which causes damage to the health of addicts seriously, and causes huge social problems. Relapse is one of the major characteristics of drug addiction, and is the main problem to be solved. In the past several decades, the mechanisms, high relapse rates, abstinence of addiction were studied. The Results of these research findings are summarized in this review to provide a better overview of the mechanisms and treatments of addition in order to provide ideas for further research.

Long-term treatment with an agonist of peroxisome proliferator-activated receptor (PPAR)-γ is associated with bone fractures in the clinical practice. However, the mechanisms underlying the fractures are not fully understood. This study was aimed to examine the effect of rosiglitazone (an agonist of PPAR-γ) of different doses on the proliferation, differentiation, and transforming growth factor beta 1 (TGF-β1)-induced expression of connective tissue growth factor (CTGF) in primary rat osteoblasts in vitro. Osteoblasts were isolated from newly born SD rats and treated with different doses of rosiglitazone (0-20 μmol/L). The proliferation and differentiation of osteoblasts were measured by MTT assay and NPP assay, respectively. The expression of CTGF was determined by RT-PCR and Western blotting. The results showed that most isolated osteoblasts displayed strong alkaline phosphatase (ALP) activity and treatment with different doses of rosiglitazone did not affect their proliferation, but significantly inhibited the differentiation of osteoblasts in a dose-dependent manner. Moreover, treatment with different doses of rosiglitazone significantly reduced the TGF-β1-induced CTGF mRNA transcription and protein expression in a dose-dependent manner in rat osteoblasts. It was concluded that the activation of PPAR-γ may inhibit the differentiation of osteoblasts by reducing the TGF-β1-induced CTGF expression in vitro.
