Objective To explore new method to extract medicine from sealing bottles and solve the problems of excess remnant in the bottles by traditional extraction method.The objective and subjective factors for excess remnant in the bottles were also discussed.Methods We stochastically selected 9392 bottles from 6 hospitals who used traditional extraction method and named them the random investigation group.We also chose 1030 bottles which were abandoned by nurses after strengthened their responsibility as the strengthened responsibility group.The medicine remnant in the bottles was recorded and compared between the two groups.Results The medicine remnant in the random investigation group was less than that of the strengthened responsibility group(P<0.01).Conclusion Application of the new method to extract medicine as well as strengthened responsibility codd leave medicine remnant as little as possible in the sealing bottles.

Objective To explore the effect of Levovist to gene transfer in skeletal muscle cells in mice.Methods H2K myoblast cells were treated by ultrasound (1 MHz,1 W/cm~2) with pulse wave (20% duty cycle) using plasmid green fluorescent protein (GFP) in vitro.Exposure duration was 10 s,20 s,30 s,40 s,50 s and 60 s.The trend of transfection efficiency by flow cytometer and cell viability by Trypan blue assays were measured.In vivo studies,transfection efficiencies were assessed by counting GFP positive fibres on mice skeletal muscle.Tissue damage was assessed on serial sections.Results Ultrasound alone showed better trend of transfection efficiency than Levovist in vitro and addition of microbubbles had the effect to reduce cell viability significantly.In vivo,Levovist with or without ultrasound had no effect on gene transfer,instead it increased tissue damage.Conclusions(Levovist showed) no effect in plasmid DNA transfection in skeletal muscle with increased tissue damage in this experimental condition.

The microbial counts, type, as well as relationship between microbial counts and the temperature of water in reticulating water system of heating pipeline in Taiyuan were studied, which the main biofouling harmful microbes included slimeforming heterotrophic bacteria, sulfate reducing bacteria, iron bacteria and fungi, respectively. The results showed that the harmful microbes in water system were lower than that of control guideline during heating period, whereas the microbes were higher than that of control guideline, which would result in biofouling of water tube during non-heating period.

Objective To explore the effect of ultrasound to gene transfer in skeletal muscle cells in mice. Methods All comparisons were performed between two intensities of ultrasound((0.5) W/cm~2, (1 W/cm~2)) with pulse wave (1 MHz, 20% duty cycle) using plasmid green fluorescent protein(GFP) on H2K myoblast cells. Exposure duration was 10 s, 20 s, 30 s, 40 s, 50 s, and 60 s. The trend of transfection efficiency by flow cytometer and cell viability by Trypan blue assays under different conditions was measured. Results GFP transfection rate in H2K cell treated by (0.5) W/cm~2 was significantly lower than that by 1 W/cm~2 as a whole. The optimum condition of GFP transfection for H2K cell was 1 W/cm~2 and (40-)50 s. Ultrasound did not increase the rate of cell-killing. Conclusions Ultrasound holds promise in gene delivery in skeletal muscle cells.

Objective To explore the effect of SonoVue to gene transfer in skeletal muscle cells in mice.Methods H2K myoblast cells were treated by SonoVue and ultrasound (1 MHz,1 W/cm2) with pulse wave (20% duty cycle) using plasmid GFP (Green Fluorescent Protein) in vitro.Exposure duration was 10 s,20 s,30 s,40 s,50 s,and 60 s.The trend of transfection efficiency by flow cytometer and cell viability by Trypan blue assays were measured. In vivo studies,transfection efficiencies were assessed by counting GFP positive fibres on mice skeletal muscle.Tissue damage was assessed on serial sections.Results SonoVue did not enhance transfection efficiency compared with positive control in vitro,instead with increased cell killing rate. In vivo,SonoVue with or without ultrasound had significant effect on gene transfer without increased tissue damage.Conclusions Although SonoVue showed no effect in plasmid DNA transfection in skeletal muscle with reduced cell viability in vitro in this experimental condition,SonoVue had significantly enhanced gene transfection efficiency in mice in vivo without increased tissue damage.

Objective To investigate the incidence and risk factors of hallucination in patients with Parkinson’s disease (PD) by using a questionnaire. Methods Ninety-one patients with PD from outpatient and inpatient departments of Neurology and 38 healthy subjects were recruited. Mini-mental state examination (MMSE), unified Parkinson's disease rating scale-Ⅲ(UPDRS-Ⅲ), Hoehn-Yahr, interleukin 6 (IL-6) and C-reactive protein (CRP) were examined in all PD. According to the PPQ-B scores, the PD patients were divided into two groups:the hallucination group (PPQ-B≥1) and non-hallucination group (PPQ-B=0). Logistic regression model was used to explore the risk factors. Results Twen?ty-nine of 91 patients had hallucination and the incidence was 32%. Age and the levels of IL-6 and CRP were signifi?cantly higher in hallucination group than in non-hallucination group. Meanwhile, the duration of illness and MMSE were significantly higher in hallucination group than in non-hallucination group. Logistic regression revealed that the age and duration of illness were independent risk factors of hallucination and the Odds Ratios (OR) were 1.09 (95% CI:1.04~1.32, P<0.05) and 1.43 (95%CI:1.21~1.87, P<0.05), respectively. The risk of hallucination increased by 51%and 59%for each doubling of IL-6 and CRP levels in PD patients and the ORs were 1.51 (95%CI:1.13~2.11, P<0.05) and 1.59 (95%CI:1.07~2.66, P<0.05), respectively. Conclusions Controlling the levels of serum IL-6 and CRP plays an impor?tant role in delay or prevention of the hallucination of PD patients.

Objective To investigate the clinical characteristics and prevalent features of an influenza erupting prevalence.Methods All of 653 patients with an erupting influenza were enrolled in the study from May 29,2003 to July 3,2003. The data included clinic manifestations and etiology. The retrospective study was used to evaluate the clinical and prevalent features. Results All patients consisted of 392 boys and 261 girls aged 5~17 years(mean 11.5 years),who were all students in middle school or primary school. Most of the patients had no typical symptoms including chill(2.45%),headache(30.00%),tiredness(10.87%)and the aching in whole body(4.44%),whereas fever,faucial inflammation and lymphatic follicular hyperplasia of the faucial posterior wall were the most common among these patients,accounting for 100%,60.03%,64.78% respectively. There were 98 patients whose peripheral leukocyte amounts were increased,most happening on the 6 ~7 th day from the onset(75.51%)following the fever on the 5~6 th day(80.6%). Detection of serum double virus-antigen indicated that influenza virus antibody increased more than 4-fold,as well as parainfluenza virus and adenovirus. Even in minority patients,there were several kinds of virus antibody raised 4-fold at the same time. We applied antivirus allopathy associated with the Chinese traditional medicine such as injection of shuanghuanglian or yuxingcao,plus the effectual antibiotics when necessary . All of the patients were cured and no sequelae. Conclusion Sometimes the influenza is prevalent only in some special crowds and has no typical symptoms such as chill,headache,tiredness and the aching in whole body.The antibiotics should be used in time after the synthetic treatment has no effect,when the patient has the onset for more than 5 days and has the fever for more than 4 days.

Objective:To investigate the effectiveness of mindfulness training improving negative emotions, furthering to explore the mediating effect of the improvement of mindfulness levels for the training effects.Methods:Randomized control trail was used in this research.Ninety participants who suffered negative e-motions and resolved to alleviate stress by mindfulness training were recruited by lecture.They were randomized in-to mindfulness training group or waitlist control group,and 79 of them completed the intervention (38 in mindful-ness training group and 41 in waitlist control group).Participants in mindfulness training group received an 8-week mindfulness training,while participants in waitlist control group received no intervention.Participants were assessed with the Five Facet Mindfulness Questionnaire (FFMQ,measuring mindfulness level)and Brief Profile of Mood State (POMS,measuring emotion)before and after intervention.Results:After 8-week intervention,participants in mindfulness training group got significantly higher total scores of FFMQ compared with baseline [(125.9 ±11.9) vs.(121.2 ±12.5),P<0.01].Participants in mindfulness training group also got significantly higher total scores of POMS,and the intensity-anxiety,depression-frustration,and fatigue scores of POMS compared with baseline (Ps<0.01).There were no significant differences between posttest and baseline on any scores in waitlist control group (Ps>0.05 ).The improvement of total scores of FFMQ mediated the reduction of total scores of POMS (95%CI=-6.24--0.73),and the intensity-anxiety (95%CI=-1.65 ~-0.12),depression-frustration (95%CI=-1.63--0.14),and fatigue scores (95%CI=-1.72--0.20)of POMS caused by mindfulness training.Conclusion:Mindfulness training could improve participants'negative emotions,and the enhanced mindfulness levels caused by mindfulness training will play a very important role for the improvement of negative emotions.

Two hundred and twenty patients with hypertensive basal ganglia hemorrhage (HBGH)undergoing cranial drilling operation and placement of soft catheter for drainage were enrolled.Among all patiems,the operation was performed at ≤6 h of disease onset in 92 cases (ultra-early group),6-24 h in 74 cases (early group) and ＞ 24 h in 54 cases (selective group).The surgery-related complications,nearterm outcome and long-term outcome were compared among three groups.In ultra-early group,recurrent hemorrhage was observed in 26 cases (28％),which was higher than that in other two groups.In selective group,there were 11 cases (20 ％) of well recovered,19 cases (35％) of moderate deformity,16 cases (30％) of severe deformity,5 cases(9％) of vegetative state and 3 fatal cases(6％) indicating that the nearterm outcome was worse than those other two groups.However there was no significant difference in longterm outcome among three groups.The rapid minimal invasive cranial drilling and soft catheter drainage is a safe and effective operation for HBGH patients and the optimal time for operation is 6-24 hours.
