ObjectiveTo explore the effect of budesonide nebulization in treatment of patients with chronic obstructive pulmonary disease and ventilator-associated pneumonia. MethodsA total of 49 cases with COPD and VAP was randomly divided into two groups:the control group consisted of 24 patients received salbutamol nebulization on the routine treatment.The observe group consisted of 25 patients received budesonide plus salbutamol bulization on the routine treatment.Variables such as TNF-αt and IL-8 in the bronchial alveolar lavage fluid(BALF),and efficacy of pneumonia and clinical healing rate were observed. ResultsThe levels of TNF-α and IL-8 in BALF of the observe group were significantly lower than those in the control group after 72h(all P＜0.05).The days of symptoms,signs and bedside chest X-ray improved,off-machine time,extubation time and the days of inpatient were statistically shorter in observe group compared with the control group(all P＜0.05).But the clinical cure rate of the observe group was no significant improvement. ConclusionThe nebulization of budesonide could suppress the local pulmonary inflammation and reduce the time of machine ventilation and improve prognosis in COPD patients with VAP.

Objective To explore the relationship between KISS-1 gene and metastasis of bladder carcinoma,and to study the effect of the stable expression of KISS-1 gene on the invasion of bladder carcinoma cell line T24.Methods Fluorescent quantitative PCR was used to detect the expression of KISS-1 mRNA in primary bladder carcinoma without metastasis and primary bladder carcinoma with metastasis.Recombinant vector pIRES2-AKS-1 was constructed and transfected into T24 cells.Single clone of stably transfected cells was screened,and the changes in the invasive ability of T24 cells was detected after transfection.Results The expression level of KISS-1 mRNA in primary bladder carcinoma with metastasis was significantly lower than that in primary bladder carcinoma without metastasis(P＜0.05).The expression of KISS-1 protein in the single clone of stably transfected cells increased significantly,and the invasive ability significantly decreased(P＜0.05).Conclusion KISS-1 gene is correlated with the metastasis of bladder carcinoma,and the up-regulated expression of KISS-1 gene can inhibite the invasiveness of T24 cell line.

OBJECTIVE To study the influence to the sterilizing effect of these factors,which were preheating the sterilizer,the positions of the articles placed and the cleanness of the internal wall.METHODS A total of 120 clinical used dental handpieces,according to the high-pressure steam sterilizer disposal procedure,were divided into four groups,with 30 handpieces in each group.Those only with high-pressure steam sterilizer process were chosen as the control group.Preheating 30 minutes,wipping the internal wall with 0.5% chlorine disinfectant before using high-pressure steam sterilizer and acting both of two steps were all chosen as the experimental groups.Each group was put in the interior,middle and exterior of the high-pressure steam sterilizer separately.The Rapid Readout Biological Indicators(3M Attest,the USA) were used to test the sterilizing effect.RESULTS The different methods of the high-pressure steam sterilizer had the significant differences to the handpieces sterilizing effect(P0.05).CONCLUSIONS To achieve ideal sterilization,it is suggested to wipe the internal wall and the temperature control probe head with 0.5% chlorine disinfectant and preheat the sterilizer for 30 minutes before put handpieces in the high-pressure steam sterilizer.

OBJECTIVETo explore the effects of different acupuncture depths of Lianquan (CV 23) for dysphagia after stroke.

METHODSTwo hundred and fifty-one patients with dysphagia after stroke were randomly divided into a deep acupuncture group (group A, 85 cases) a shallow acupuncture group (group B, 83 cases) and a glossopharyngeum acupuncture group (group C, 83 cases). Based on the conventional treatment, the glossopharyngeum acupuncture which was pricking without needles retained at lingual surface, posterior pharyngeal wall of the affected side, Jinjin (EX-HN 12) and Yuye (EX-HN 13) was used in the three groups. After the glossopharyngeum acupuncture, Lianquan (CV 23) was acupunctured 60-70 mm in the group A and 30-40 mm in the group B. The needles were all retained for 30 min. The treatment was applied once a day for 30 days in the three groups. Water swallowing test evaluation scale was observed before and after treatment, and the efficacy was assessed in the three groups.

RESULTSThe total effective rate was 95.3% (81/85) in the group A, which was better than 85.5% (71/83) in the group B and 83.1% (69/83) in the group C (both P < 0.05). The water swallowing test scores were decreased apparently in the three groups (all P < 0.01), and scores in the group A were the most obvious decline (P < 0.01). The decrease of scores in the group A was more remarkable than those in the group B and the group C after two weeks of treatment (both P < 0.05).

CONCLUSIONAcupuncture at Lianquan (CV 23) can effectively improve the dysphagia after stroke. The acupuncture depth can affect efficacy and the effect of deep acupuncture is better.

Objective To explore a new method for one-stage repair of the intestinal leakage based on the principle of magnetic compression anastomosis. Methods Twenty-four dogs were randomly divided into experimental group (n = 12) and control group (n = 12) according to random number table. The model of upper and multiple intestinal leakages was established by making transverse incisions of 1 cm in length on the jejunum wall about 50 cm and 100 cm away from the Treitz ligament. Forty-eight hours later, two NdFeB magnetic rings with the magnetic flux of 2500 G were put into the intestine from the leak sites. The leak sites were pressed between the two rings. The ventages in the control group were sutured. The condition of the dogs was observed after the repair of the leakage. The excreting time was recorded, and the leakage pressures of the anastomotic stoma were detected.The positions of the magnetic rings in the experimental group were detected by X ray. Tissues of the anastomotic stoma were processed by hematoxylin eosin and Masson staining. All data were analyzed using the two-sample t test. Results Severe abdominal infection occurred 48 hours after the establishment of the model. All the intestinal leakages in the experimental group were successfully repaired and the dogs survived for a long time. The magnetic rings were excreted six or seven days after the repair. Eight dogs of the control group survived. The leakage pressure of the anastomotic stoma seven days after the repair was (134 ±23)mm Hg (1 mm Hg =0. 133 kPa) in the experimental group and (91 ± 18)mm Hg in the control group, respectively, with a significant difference between the two groups (t = 3.225, P ＜ 0.05). The leakage pressure of the anastomotic stoma 14 days after the repair was (281 ±7)mm Hg in the experimental group and (271 ±21) mm Hg in the control group, respectively, with no significant difference between the two groups (t =0. 988, P ＞ 0.05). Histological observation showed that after the magnetic compression anastomosis, the intestinal muscle and mucosa recovered well, inflammatory reaction was slight and less collagen fiber and scar was formed. Conclusions Application of magnetic ring with the magnetic flux of 2500 G in one-stage repair of the intestinal leakage in the state of severe abdominal infection is safe and reliable.
