Objective To study the application of 3％ hypertonic saline (HS) in patients with severe craniocerebral injury after operation.Methods Sixty-eight cases with severe craniocerebral injury after operation were divided by random digits table method into HS group and control group with 34 cases each.The patients in control group were treated with 125 ml 20％ mannitol every 6 hours or 8 hours.The patients in HS group were given conventional mannitol and added with 130 ml 3％ HS every 12 hours or 8 hours through fast intravenous drip altemated with mannitol.The levels of intracranial pressure (ICP),mean arterial pressure (MAP),central venous pressure (CVP) were recorded within 6 hours,12 hours,24 hours of the 1st day,24 hours of the 2nd day,24 hours of the 3rd day,24 hours of the 5th day.The Na+ level of blood serum and the plasma osmotic pressure were recorded and calculated within 12 hours,24 hours of the 1st day,24 hours of the 2nd day,24 hours of the 3rd day,24 hours of the 5th day.The Glasgow coma scale( CCS) score was accounted within 24 hours of the 1 st day,24 hours of the 3rd day,24 hours of the 5th day.Results Compared with control group,the level of ICP in HS group decreased at every time point (P ＜ 0.05).The tendency of ICP in two groups was not significant on the 1st and 2rid day (P ＞ 0.05 ),but the level of ICP within 24 hours of the 3rd and 5th day obviously increased compared with those of the 1st and 2nd day (P＜0.05).The levels of MAP and CVP in HS group were significantly higher than those in control group within 6 hours,12 hours and 24 hours of the 1 st day and 24 hours of the 2nd day [ ( 87.98 ± 5.03 ),(88.56 ± 5.36),(87.04 ±6.90),(90.03 ±5.19) mm Hg (1 mm Hg =0.133 kPa) vs.(77.98 ±5.09),(79.98 ±6.09),(80.98 ± 5.27),(81.98 ± 4.32) mm Hg and (9.23 ± 1.24),(9.67 ± 1.35),( 10.21 ± 1.38 ),( 10.56 ± 1.96)mm Hg vs.(7.15 ± 2.01 ),(8.32 ± 1.53),(8.67 ± 1.89),(9.22 ± 2.03) mm Hg] (P ＜ 0.05),but the values within 24 hours of the 3rd and 5th day between two groups had no significant differences (P＞ 0.05 ).The Na+ level of blood serum and the plasma osmotic pressure in HS group at every time point was obviously higher than that in control group (P＜ 0.05).The GCS scores within 24 hours of the 1st,3rd and 5th day in HS group were (4.21 ± 2.31 ),(5.44 ± 2.46 ),(7.23 ± 1.64 ) scores,respectively,while the scores in control group were (4.14 ± 2.10),(5.15 ± 2.31 ),(7.31 ± 2.12) scores,respectively ;the score within 24 hours of the 5th day in two groups was obviously higher than that of the 1st day respectively (P＜ 0.05 ),but the scores between two groups had no statistical significance (P＞ 0.05 ).Conclusions Adding 3％ HS is more effective to decrease ICP,improve the brain perfusion and reduce the adverse reactions.3％ HS can be used as the first-line therapy for patients with severe craniocerebral injury after operation.

Objective To observe the effects of lung protective ventilation strategy (LPVS) on inflammatory mediators in bronchial alveolar lavage fluid (BALF) in pulmonary and extrapulmonary acute respiratory distress syndrome(ARDS).Methods All of 62 extrapulmonary ARDS(ARDSexp) cases and 60 pulmonary ARDS (ARDSp) cases were divided into observation group and control group by table of random digit.ARDSexp and ARDSp observation group were received LPVS treatment [tidal volume 6-8 ml/kg,positive end expiratory pressure (PEEP) 5-15 cm H2O (1 cm H2O =0.098 kPa)],and ARDSexp and ARDSp control group were received the routine ventilation strategy (tidal volume 10-12 ml/kg,PEEP 4-8 cm H2O).All groups were treated with the same conventional therapy of ARDS,same model and parameter of mechanical ventilation.The level of tumor necrosis factor (TNF)-α,interleukin (IL)-6,IL-8 in BALF were tested by enzyme linked immunosorbent assay on the 1st,4th,7th day in each group.The oxygenation index was tested at 8 o'clock each morning.Results There were 4 ARDSexp cases and 6 ARDSp cases who were expelled,because of death within 7 days.ARDSexp observation group was in 28 cases,ARDSexp control group was in 30 cases,ARDSp observation group was in 28 cases,ARDSp control group was in 26 cases.The oxygenation index had no significant difference between ARDSexp and ARDSp observation group and corresponding ARDSexp and ARDSp control group on the 1st and 2nd day (P ＞ 0.05).But the oxygenation index in ARDSexp and ARDSp observation group were significantly higher than that in ARDSexp and ARDSp control group from 3rd to 7th day (P ＜ 0.05).The oxygenation index in ARDSexp observation group was significantly higher than that in ARDSp observation group except 1st day (P ＜0.05).The oxygenation index in ARDSexp and ARDSp observation group were significantly better with the time passing (P ＜ 0.05).The BALF levels of TNF-α,IL-6 and IL-8 in ARDSexp and ARDSp observation group were significantly lower than those in corresponding ARDSexp and ARDSp control group on the 4th and 7th day (P＜ 0.05).The BALF levels of TNF-α,IL-6 and IL-8 in ARDSexp observation group and ARDSexp control group were significantly lower than those in corresponding ARDSp observation group and ARDSp control group (P＜ 0.05).The BALF levels of TNF-α,IL-6 and IL-8 in ARDSexp and ARDSp observation group were decreased significantly with the time passing (P ＜0.05).Conclusion It is more reasonable to decrease the BALF levels of inflammatory mediators,increase oxygenation index for ARDS patients to with LPVS treatment,then for ARDSexp patients obviously.

Objective To observe the therapeutic effects of the drugs alternation multiple stages and long term therapy in elderly patients with recurrent urinary tract infection.Methods The patients were divided into elderly group (age≥65 years,n=30) and non-elderly group (n=48).The multiple effective antibiotics were selected for alternate use.The treatment included four periods as follows:(1)Treatment period:the regular dose of antibiotic was maintained until the urine routine test result became normal;(2)Consolidation period:the dosage of antibiotic was reduced;(3)Maintenance period:the dosage of antibiotic was reduced to once every night and the treatment should be kept for three months;(4)Observation period:the patients were observed for six months after withdrawal of antibiotics.During the treatment,if the urine routine test became abnormal repeatedly,the patient should return to the previous treatment period.During the treatment and consolidation period,each medication should be applied for one week alternatively.Results Among 78 patients,69 cases (88.5%) were cured,7 cases (8.9%) were effective,and two cases (2.56%) were invalid.There were 28 cured cases,1 effective case and 1 invalid case in elderly group.The corresponding data were 41,6 and 1 in non-elderly group,respectively.There was no difference in cure rate between the two groups (F= 0.469).Compared with non-elderly group,the overall treatment time [(54.8± 16.2)weeks vs.(44.5± 13.7) weeks,t= 2.8467,P＜0.01],treatment period [( 34.3± 15.2) weeks vs.(26.2±14.8) weeks,t=2.2081,P＜0.05] and consolidation period [(5.7±2.6) weeks vs.(4.1±0.2) weeks,t=3.9369,P＜0.01] were all prolonged in elderly group.But there was no difference in maintenance period [(14.8±4.6) weeks vs.(14.2±3.1) weeks,t=0.6480,P＞0.05].There were no markedly changes in blood routine,liver and kidney function during the course of treatment.Conclusions For the elderly patients with recurrent urinary tract infection,the drugs alternation,multiple stages and long-term treatment has a high cure rate and no adverse effect on blood routine,liver and renal function.

Objective: This study was to develop an experimental rat model of subcutaneous fistula induced by bacteria infection and treat it with thread-dragging therapy. Methods: A spring-gauze was surgically implanted into 24 male Sprague-Dawley rats' dorsal muscles, respectively, then mixed Staphylococcus aureus and Escherichia coli were injected into the spring-gauze. After 45 d, all the spring-gauzes were removed from the rats under anesthesia. X-ray and ultrasound were performed to assess the fistula tract. Each rat was examined by a fistula probe and four rats were randomly selected for histological assessment. The residual rats were randomly divided into two groups. Group A was treated with thread-dragging therapy, and group B was treated with fistulotomy. The healing time and body weight of the two groups were compared. Results: On the 45th day of the spring-gauze implantation, imaging assessment proved a tract with two openings in all rats and histological results proved that lumen and surrounding granulation tissue with epithelium were similar to the features of fistula in human beings. The mean healing time of rats in group A was shorter than that of the rats in group B (P<0.01). The body weight of rats in group A was heavier than that of the rats in group B on the 7th and 14th day after surgery, respectively (P<0.05). Conclusion: A rat model of subcutaneous fistula induced by mixed Staphylococcus aureus and Escherichia coli infection was successfully established. Traditional Chinese medicine thread-dragging therapy is less invasive and safer than fistulotomy.

Objective To investigate the impact of paced QRS duration (pQRSd) on heart function in patients with right ventricular apical pacing. Methods Seventy-six patients with Ⅲ° atrioventricular block received pacemaker treatment were enrolled and randomized into group A (pQRSd < 190 ms, n = 52) and group B(pQRSd≥ 190 ms, n = 24). The concentration of brain natriuretic peptide (BNP),parameters of left atrial diameter (LAD), left ventricular ejection fracetion (LVEF), left ventricular end diastolic diameter (LVEDD), left ventricular end systolic dimension (LVEDD) were measured before operation, at 12 months and 24 months after implanting, respectively. The parameters of echocardiography assay, the concentration of BNP and the incidence of heart failure event after implantation were compared between two groups. Results At 12 months after implanting, LVEF of the patients in the group B decreased significantly compared with that of group A (P < 0.05). However, the echocardiography paramenters and the concentration of BNP were not significantly different between the two groups (P > 0.05). At 24 months after implanting, LAD、LVEDD、LVESD of group B increased significantly compared with those of group A [LAD,( 44.5 ± 6.2) mm vs (41.6 ± 5.1) mm, LVEDD, (52.7 ± 9.3) mm vs (48.2 ± 7.5) mm, LVESD, (37.5 ± 5.6) mm vs (33.8 ± 4.9)mm, each P < 0.05, respectively]. The concentration of BNP of group B increased significantly [(408.2 ± 102.1)ng / L vs (243.7 ± 92.8)ng / L, P < 0.001], and LVEF of the patients in group B decreased significantly compared with those of group A [(46.3 ± 6.8)% vs (51.6 ± 5.2)%, P < 0.001], respectively. No significant difference in the incidence of heart failure event (41.7% vs 26.9%, P > 0.05)between two groups during 24-month follow-up. Conclusion The prolonged paced QRS duration has a detrimental effect on long-term cardiac function during RVA pacing in patients with Ⅲ°atrioventricular block.

OBJECTIVETo study the role of integrin-linked kinase (ILK) on the proliferation and differentiation of human fibroblast in hypertrophic scar and its effect on the scar formation.

METHODSThe human scar fibroblasts were isolated and cultured in vitro. The cells were divided into 4 groups. (1) control group: only contains DMEM; (2) jetPRIME group: DMEM with 200 microl jetPRIME buffer and 4 microl jetPRIME; (3) ILK siRNA group: DMEM and ILK siRNA; (4) ILK cDNA group: DMEM and ILK cDNA. The cell proliferation was detected by XTT assay and the mRNA and protein expressions of ILK and alpha-SMA were detected by Real-time qPCR and Western blot.

RESULTS(1) XTT results showed that the cellular proliferation level after 48 h in four groups were 0.820 +/- 0.065, 0.873 +/- 0.041, 0.554 +/- 0.013 and 1.296 +/- 0.094, respectively. The cellular proliferation curve showed that the cellular proliferation level was very flat in ILK siRNA group while the cellular proliferation level gradually increased from 12 h. 48 h after transfection, the cellular proliferation level in ILK siRNA group was significant lower than those in other groups (P value were 0.021, 0.034, 0), while the cellular proliferation level in ILK cDNA group was the highest among all 4 groups (P value were 0.017, 0.009, 0). (2) The Real-time qPCR showed that the expressions of ILK mRNA and alpha-SMA mRNA were 0.693 +/- 0.412 and 0.422 +/- 0.037 in control group, were 0.621 +/- 0.183 and 0.388 +/- 0.005 in jetPRIME group, were 0.052 +/- 0.019 and 0.073 +/- 0.023 in ILK siRNA group, were 240.193 +/- 35.170 and 138.056 +/- 24.060 in ILK cDNA group. The expressions of ILK mRNA and alpha-SMA mRNA in ILK siRNA group were significantly lower than those in other three groups (P < 0.05). And the expressions of ILK mRNA and alpha-SMA mRNA in ILK cDNA group were significantly higher than those in other three groups (P < 0.05). (3) The Western blot also showed that the expression of ILK and alpha-SMA proteins were decreased in ILK siRNA group and increased in ILK cDNA group.

CONCLUSIONILK may promote the proliferation and differentiation of human scar fibroblast. It may play an important role in scar formation and contracture.
