Pseudomonas fluorescens is one of the most common contaminative bacteria of the stored blood. Ps. fluorescens No. 10-36 was cultured at 4℃, 22℃ and 37℃ for studying its growth phase and logarithmic growth phase. The results showed that this strain grew slowly at 37℃ with a generative rate of 900 minutes, but had no difference between the lag phase and the logarithmic growth phase. At 22℃ the lag phase were 5 hours, and the logarithmic growth phase were 29minutes, while at 4℃, the lag phase was 30 hours and the logarithmic growth phase was 300 minutes.

CYP2A6 is an important drug metabolic enzyme that plays a central role in pharmacology and toxicology.Coumarin and nicodine are mainly metabolized by it.CYP2A6 also have a close connection with diseases that related to smoking.While hnRNP A1 is a protein that shows an important regulative action on some specific genes at post-transcription level.Recently,researchers are paying more and more attention to the relationship between the activity of CYP2A6 and the expression of hnRNPA1.In order to master the change rule of CYP2A6 activity,we try to explain the regulative effect on CYP2A6 by hnRNP A1 at post-transcription level,which will bring an important effect on guiding clinical medicine treatments and smoking addictive therapy.

Objective To evaluate the clinical effect of levofloxacin combined with Jingangteng particle in the treatment of patients with chronic pelvic inflammatory disease.Methods According to the random number table, sixty -four patients with chronic pelvic inflammatory disease were divided into control group(n =32)which were treated with levofloxacin and treatment group(n =32)which were treated with levofloxacin and Jingangteng particle for three weeks.The clinical effect,symptoms and signs were evaluated and the adverse reactions between the two groups were observed as well as serum C reactive protein(CRP)were measured before and after treatment.Results The score of symptoms and signs of the treatment group were significantly lower than the control group,the difference was statistically significant [(2.61 ±2.09 )points vs.(5.32 ±3.28)points,t =3.941,P =0.000;(1.47 ± 1.02)points vs.(2.56 ±2.04)points,t =2.703,P =0.008].The level of serum CRP of the control group was (5.46 ± 1.93)mg/L,which was statistically higher than (3.76 ±1.06)mg/L of the treatment group after treatment,the differ-ence was statistically significant (t =4.367,P =0.000).The total effective rate of the treatment group was 96.9%, which of the control group was 78.1%,the difference between the two groups were statistically significant(χ2 =5.142,P =0.023).There was no significant adverse reactions during the treatment.Conclusion Levofloxacin com-bined with Jingangteng particle can obviously improve the symptoms and signs of chronic pelvic inflammatory disease, they have good safety and are worthy of clinical popularization and application.

The human bronchial arteries and their anastomoses with pulmonary vessels were studied on normal and diseased lungs in 30 adult and infant cadavers under a magnification of 3～40 times.The bronchial arteries pursue a tortuous serpentine course along the surface of the bronchi. They divide either before or after the bifurcation of the bronchi and often send two branches coursing along each bronchus with one branch on each side of the bronchial wall. These branches usually form a network in the fibrous coat of the bronchus. Smaller twigs penetrate the bronchial walls and form a similar network in the submucosa.Mediastinal pleural branches and interlobar pleural branches of the bronchial arteries have their subpleural, independent course from the bronchial tree and their larger caliber at peripheral sites.In the visceral pleura and on the surface of the bronchi or within the bronchial wall, there are precapillary anastomoses between the bronchial and pulmonary arteries, and between the bronchial artery and pulmonary veins. The anastomoses occur either end to end or end to side.In the pleural adhesions of 9 cases of the lungs, the newly developed pleural branches arising from the intercostal, the superior intercostal, the pericardiophrenie or the internal mammary artery, anastomose with the bronchial artery via pleural arterial network to reinforce the blood supply for the diseased pulmonary area.The important physiological function of the anastomoses between the bronchial arteries and pulmonary vessels, as well as the course and distribution of the bronchial arteries in the lungs were discussed.

OBJECTIVE To explore optimal change dressing of the incision of trachea.METHODS Seventy-eight patients were randomly and equally divided into the traditional group and test group.In traditional group,after dressings change with conventional disinfection,the sterile gauze was cut into "E" shape and overlapping covered on the incision of trachea around the trachea cannula from top to bottom and fixed with adhensive plaster.In test group,after dressings change with conventional disinfection,the special sterile drainage was fixed and smoothed around the trachea cannula from left to right(or from right to left).RESULTS In test group,skin incision colonies of patients were significantly lower than that in traditional group(P

This study was aimed to determinate the content of quercetin from different parts (such as flowers, fruits, stems, leaves and branches) of Penthorum chinense Pursh. from Sichuan province so as to offer reference for the comprehensivedeve lopment and utilization of P. chinense Pursh. The quantitative determination of quercetin from five groups of different parts of P. chinense Pursh. were carried out and put into comparison by the reversed-phase high performance liquid chromatography (RP-HPLC). The results showed that there were larger differences of content among different parts. The highest content of the medical parts were flowers and fruits, which was followed by the leaves, stems and branches. It was concluded that different parts (such as flowers, fruits, stems, leaves and branches) of P. chinense Pursh. from Sichuan province should be divided in the clinical and productive practice, which was to supply the scientific basis for enhancing the curative effect and reasonable exploitation and utilization of the resource of P. chinense Pursh.

This study was aimed to analyze the influence of specific clinical effect of Dioscorea opposita Thunb. by dosage in order to summarize its rules. Recordings on pills containing D. opposita Thunb. from the classic prescrip-tion of the Formula Dictionary of Traditional Chinese Medicine were collected. Dosage of D. opposita Thunb. was used as the cardinal line. EXcellwas used to conduct schematic analysis. The results showed that small amount of D. opposita Thunb. had the effect of reinforcing the spleen. The effect of tonifying the lung had the dosage boundary line of 10 g. The small dosage had weak effect and large dosage had strong effect. The effect of tonifying the kidney was often the middle dosage. When the dose was larger or smaller, the effect was not obvious. The effect of consoli-dating the kidney was obvious when using larger or smaller dosage. It was concluded that the dosage of D. opposita Thunb. had relatively big influence on its effect, which provided reference of more value for the clinical practice and health cultivation.

Result The correlation coefficients between the total score of ASRSYC and the verbal scale score , performance scale score and full scale score of C - WYCSI were 0. 85, 0.70and 0. 81, respectively. The corrdlations between the total score of ASRSYC and the subtest scores of C - WYCSI ranged from 0. 51 to 0. 75 . Conclusion Adaptive skills and intelligenoe in young children relate each other and develop jointly.

Objective To evaluate the value of ultrasonic mini probe(UMP) in the diagnosis of lower digestive tract lesions . Methods one hundred and fifteen patients with lesions of lower digestive tract were undergone EUS with UMP (Olympus UM-3R, 20MHz; UM-2R, 12MHz). Results Eighty one cases with colorectal carcinoma appeared as a hypoechoic mass under UMP. UMP had an overall accuracy rate of 82. 7% (67/81) in the diagnosis of depth of infiltrative colorectal carcinoma. The sensitivity and specificity of UMP in the diagnosis of lymph node metastasis were 55. 4% and 68. 8% respectively. All 15 cases with submucosal tumors were diagnosed correctly under EUS except one leiomyoma misdiagnosed as leiomyosarcoma and other 10 and 9 cases were ulcerative colitis and Crohn's diseases respectively. Conclusions UMP has a high accuracy in determining the invasive depth of colorectal carcinoma and submucosal tumors. The preoperative UMP may provide much information and influence on the choice of therapy for colorectal carcinoma and submucosal tumors.
