OBJECTIVE To understand the pharynx colonization and drug resistance among normal population,drug-dependent people and mentally ill people.METHODS There were 3 groups divded.The health care workers were the randomly selected to group A of forced detoxification 299 specimen from throat swab were collected from the drug dependent people(in stage group B 199 examples),and the mentally ill people(group C,99 examples).The throat swab samples were inoculated into the blood agar,MacConkey and XV/phenylethanol double-plate,and cultured commonly and anaerobic allg at the same time,and the strains were identified and the sensitivity was tested.RESULTS From the three groups,Haemophilus influenzae,H.parainfluenzae,Staphylococcus aureus and other strains.were detected out But in group B were detected out Haemophilus paranaemolyticus,Klebsiella pneumoniae subsp ozaenae and Pseudomonas aeruginosa strains.Pantoea agglomerans,Serratia marcescens,and A streptococcus were detected out in group C.CONCLUSIONS In the three group similar types of pharyngeal bacteria were found the colonization rates of different strains among the three groups are different,the resistance is also different,The work is in favor to provide a reliable basis for clinical treatment.

Objective To evaluate surgical treatment for different types of tumor of the suprarenal infrahepatic segment of the inferior vena cava (IVC).Methods A retrospective analysis was made on 8cases of IVC leiomyosarcoma at the suprarenal infrahepatic IVC segment.According to the extent of tumor invasion and collateral circulations,operations included tumor resection plus inferior vena cava reconstruction or tumor resection plus right nephrectomy.Results Tumors were completly resected in all patients.Renal function recovered after operation.During a follow up of 24 mons,7 cases had no recurrence.One case with recurrence after 12 months underwent successful resection and is doing well after a follow-up of 12 months.Conclusion CT and inferior vena cavography can determine the extent of tumor invasion and collateral circulations helping select appropriate surgical aproach before the operation resulting in less renal injury.

Objective:To explore the possible effects of Bushen Huoxue Formula (the kidney tonifying and blood activating prescription) on the proliferation and extracellular matrix synthesis of nucleus pulposus cells by regulating the circ_0036763/miR-583 axis.Methods:Real time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression levels of circ0036763 and miR-583 in normal and intervertebral disc degeneration (IDD) nucleus pulposus cells; IDD nucleus pulposus cells were divided into pcDNA group, pcDNA circ_0036763 group, pcDNA circ_0036763+ mimic NC group, and pcDNA circ_0036763+ miR-583 mimic group. qRT-PCR was used to detect the expression levels of circ_0036763 and miR-583 in nucleus pulposus cells in each group, methyl thiazolyl tetrazolium (MTT) was used to detect cell proliferation (A value), and Western blot was used to detect the expression of proliferating cell nuclear antigen (PCNA), collagen Ⅰ, and collagen Ⅱ proteins in nucleus pulposus cells, The dual luciferase assay reported experimental validation of the targeting relationship between circ_0036763 and miR-583. 27 mice were divided into sham surgery group, IDD group, and kidney tonifying and blood activating formula group. IDD models were established in all groups except for the sham surgery group. After successful modeling, the sham surgery group and IDD group were given physiological saline by gavage, while the kidney tonifying and blood activating formula group was given 1.5 g/ml of kidney tonifying and blood activating formula by gavage for 3 consecutive weeks. QRT-PCR was used to detect the expression levels of circ0036763 and miR-583 in the nucleus pulposus cells of mice in each group, MTT was used to detect cell proliferation, and Western blot was used to detect the expression of PCNA, collagen Ⅰ, and collagen Ⅱ proteins.Results:The expression level of circ_0036763 in IDD nucleus pulposus cells decreased, while the expression level of miR-583 increased (all P<0.05); Overexpression of circ_0036763 can promote proliferation and extracellular matrix synthesis of nucleus pulposus cells (all P<0.05); Circ_0036763 targets miR-583 and upregulates miR-583 reversible overexpression. Circ_0036763 enhances the proliferation and extracellular matrix synthesis ability of IDD nucleus pulposus cells. Compared with the sham surgery group, the IDD group showed an increase in collagen Ⅰ protein expression and miR-583 expression levels (all P<0.05), while the cell A value, PCNA and collagen Ⅱ protein expression, and circ_0036763 expression levels decreased (all P<0.05); Compared with the IDD group, the Kidney Tonifying and Blood Activating Formula group showed a decrease in collagen Ⅰ protein expression and miR-583 expression levels (all P<0.05), while the cell A value, PCNA and collagen Ⅱ protein expression, and circ_0036763 expression levels increased (all P<0.05). Conclusions:The kidney tonifying and blood activating formula (Bushen Huoxue) may induce proliferation and extracellular matrix synthesis of nucleus pulposus cells by regulating the circ_0036763/miR-583 axis.
