Objective To investigate a new method to reduce air bubbles formation during drug preparation. Methods 200 portions of drugs from hospital pharmacy were randomly divided into the control group and the experimental group with 100 portions in each group. In the experimental group, the infusion bags were put flat on the desktop, the needles pierced into the bags parallel, and immersed in the liquid inside. In the control group, the infusion bags were put perpendicular to the desktop, the needle pierced into the bags vertically, the needles do not immersed in the liquid. Air bubble formation in the infusion bags was compared between the two groups. Results Air bubble formation in the experimental group was significantly less than that of the control group. Conclusions The modified new method for drug preparation can reduce the formation of air bubbles.

AIM: To investigate the role of adrenomedullin (AM) in diabetic nephropathy. METHODS: We observed the changes in the expression and secretion of AM, TGF-? 1 in the cultured human mesangial cells under high glucose condition and the contents of the laminin and type IV collagen in the supernatants. The effect of intervention with AM was also observed. RESULTS: High glucose condition resulted in increase in the expression and secretion of AM TGF-? 1 laminin and type IV collagen. AM reversed the influence of high glucose on the cultured human mesangial cells. CONCLUSION: These results showed that high glucose condition is one of stimulating factors of AM and the renal protective action of AM may be associated with suppression of TGF-? 1 and reducing excessive accumulation of laminin and type IV collagen.

Objective To evaluate the effectiveness of using low-frequency repetitive transcranial magnetic stimulation (rTMS) along with donepezil in the rehabilitation of aphasia after cerebral infarction. Methods Fortythree aphasic patients with acute cerebral infarction were assigned into a treatment group or a control group.Both groups received standard basic treatment for acute cerebral infarction.From day 7 on,both groups received oral donepezil hydrochloride (5 mg/d) for 12 consecutive weeks.The treatment group received in addition 2 sessions of low frequency rTMS on the language center of the right hemisphere.The first session started at day 7 after onset,and each session consisted of rTMS on 10 consecutive days (once per day).There was a resting interval of 3 d between the two sessions.The rehabilitation of the aphasia was assessed prior to and after each session,and at the end of the entire 12 weeks of treatment using the western aphasia battery ( WAB ) scoring system and the aphasia quotient (AQ). Results There was no significant difference between the two groups after the first session in terms of the WAB or AQ results.However,the difference in improvement became statistically significant after the second session,as well as at the end of the entire 12 weeks.The average change in AQ was significantly greater in the treatment group. Conclusion Donepezil combined with rTMS early in the acute phase of cerebral infarction is helpful for the rehabilitation of aphasia.

AIM: To aim to seek the best operation conditions of the inorganic ceramic membrane in the separation of effective matters from the homogenate of earthworm. METHODS: The homogenate flux was adopted as index,to select the membrane material,filter pressure、homogenate temperature and concentration. RESULTS: The experiment showed that the filter flux had a significant positive correlation with pressure difference and liquid temperature,and negative correlation with liquid concentration. CONCLUSION: In the separation of earthworm homogenate,0.2 ?m Al_2O_3 and 50 nm ZrO_2 film pipe were respectively selected as primary and secondary separating unit on the condition of 0.15 mPa pressure,50 ℃ and 33.%(w/w) homogenate concentration.

Objective To establish an immunohistochemical method for postmortem diagnosis of electrocution. Method 12 rats were divided into two groups,experimental and control. In the experimental group,6 rats were killed by electricity,and in the control group,6 rats were killed by breaking the rats' neck. Myocardium sections were then made and were stained by SABC immunohistochemical method as well as HE.Results The expression of the fibronectins in the experimental rats' myocardia were significantly increased as compared with those in the control rats (P

Medical genetics is the mutual penetrative and combined discipline of genetics and medicine.Medical genetics teaching should be improved to adapt to the discipline development.Teaching reform and practice of medical genetics was developed in basic medical college of Nanjing university of traditional Chinese medicine.Constructive exploration was made in teaching content,teaching techniques,teaching methods,scientific research and performance appraisal standards in order to improve the quality of medical genetics teaching and to train high-quality medical talents.

Objective To investigate the therapeutic effects of repeated transcranial magnetic stimulation (rTMS) at high and low frequency for the rigidity and tremors of Parkinson's disease (PD).Methods Sixty-nine patients with PD received rTMS at 5 Hz or 0.5 Hz.The efficacy was assessed using the unified Parkinson's disease rating scale (UPDRS),motor function tests and motor evoked potentials (MEPs).Results Thirty-two patients with rigidity from PD received 5 Hz rTMS therapy,and their UPDRS total scores decreased significantly.Their motor function test results improved significantly and their MEP relaxed motor thresholds were significantly elevated.Thirtyseven patients with tremors from PD received 0.5 Hz rTMS therapy,and their UPDRS total scores were significantly decreased.Their motor function test results improved significantly and their MEP relaxed motor thresholds were significantly elevated.Conclusion High frequency rTMS may improve the symptoms of patients with PD rigidity and low frequency rTMS may improve the symptoms of patients with PD tremors.

Objective To investigate the braking time in diagnosis of lipohemarthrosis by ultrasound. Methods Experiment group:After 20 tubes containing fresh blood and pig marrow were uniformly mixed, they were instantly continuously detected by high-frequency linear array transducer in fixed-area at short-interval.Clinical group: Ten walking patients with lipohemarthrosis were examined with continuous detection by ultrasound,CT and MR before operation.Results Experiment group: Cloudy echo and slowly floating up of lipoids were detected at the beginning.After 2.7 to 3.7 minutes (average 3.17 minutes), the liquid was divided into two layers with vague boundary.After 5.3 to 8.0 minutes (average 6.75 minutes) ,the liquid was divided into 3 layers with thickening serum laye.Clinical group: Ultrasound findings: Cloudy medium echo was detected at first.After 2.0 to 4.0 minutes (average 3.08 minutes),the liquid was divided into two layers.After 4.4 to 10.0 minutes (average 6.92 minutes) , the liquid was divided into 3 layers with thickening serum layers.Three knees showed fracture line and 2 knees with occult fracture were diagnosed as lipohemarthrosis.CT and MR findings: Ten knees showed fracture line in CT examination,of which 7 knees showed double liquid-liquid layer and 3 knees showed single liquid-liquid layer in the suprapatellar bursa.Ten knees showed fracture line in MR examination,6 knees showed double liquid-liquid layer and 4 knees showed single liquid-liquid layer in the suprapatellar bursa. Conclusions The best braking time in diagnosing lipohemarthrosis by ultrasound can be shorten to 10 minutes and the necessary braking time is 2 to 4 minutes.
