[Objective]To review our experience in treatine infection after total knee arthroplasty with debridement and component retention to determine To the feasibility,indication,factors related to success and failure,and the main points of technique.[Method]Since 1990 to 2004,9 patients were treated with debridement and component retention at our department.[Result]Four of 9 patients successfully retained their component at most recent follow-up,without ongoing infection(mean 18 months,range 10～25 months).We have not draw the statistically significant factors that related to successful and failure,but the factors such as acute infection,surfacing replacement,immediate debrided after onset of symptoms,and the bacteria sensitive to antibiotic were relate to success.[Conclusion]Debridement and component retention can be used in acute postoperative infection and later acute hematogenous infection after total knee replacement,but timing and indication must be chosen strictly.

The confirmation of maxillomandibular relation is the key step to manufacture complete denture. Certain kind of transformation and shift will lead to the inaccuracy in the progress of the confirmation of maxillomandibular relation, while these problems could be avoided by applying remodified vacuum-formed occlusal pad. In this way, accuracy of the confirmation of maxillomandibular relation and the clinical effect can be enhanced.

Pre-disease is a condition in which characteristic symptoms are not prominent.That is to say pre-disease is lack of key proof to be diagnosed as a disease,but has common symptoms as well as signs.It is said in Inner Canon of Huangdi that "prefer prevention to treatment",which needs doctors to find unusual symptoms in early stage of diseases then take positive preventive measures to help patients regain health.Diabetes mellitus(DM) is one of the life style-related diseases which associated with unhealthy habits of human beings.Pre-diabetes mellitus mainly refers to impaired glucose tolerance(IGT).With the help of modern medical technology,doctors and patients should focus on pre-diabetes by combining TCM treatment based on syndrome differentiation and health care,in order to stop DM at early stage.

Objective To investigate the clinical study of sarcoside combined with tamsulosin in the treatment of type Ⅲ prostatitis. Methods 84 patients with type Ⅲ prostatitis who were treated and diagnosed in Jishuitan Hospital from November 2015 to December 2016 were randomly divided into experimental group and control group according to the time of hospitalization, 42 cases in each group. The control group was treated with tamsulosin hydrochloride sustained-release capsules, and the experimental group was treated with the addition of the new drug. The maximum urinary flow rate and mean urinary flow before and after treatment were recorded, compared and analyzed before and after treatment. Results The maximum urinary flow rate and mean urinary flow rate were increased in both groups after treatment, and there was significant difference between the two groups (P<0.05). The data of the maximum urinary flow rate and the mean urinary flow rate in the experimental group were significantly better than those in the control group. The data of the two groups were statistically significant (P<0.05). In addition, the experimental group after treatment of prostate symptom score was significantly better than the control group score, the two groups of data were significantly different, the data were statistically significant (P<0.05). In addition, the total effective rate of the experimental group was significantly higher than the control group(80.95%vs. 73.81%). The data were statistically significant (P<0.05). Conclusion The clinical efficacy of sorbenaside combined with tamsulosin in the treatment of type Ⅲ prostatitis is better than that of the original treatment. The treatment can improve the patient's urination and prostate symptoms and improve the patient's comfort.

BACKGROUND: Three-dimensional printing to prepare a digital model can improve the accuracy of orbital fracture repair, and has a good clinical prospect.OBJECTIVE: To evaluate the effect of individualized titanium mesh based on the digital model in the reconstruction of orbital fracture.METHODS: Twelve cases of orbital fracture were admitted at the Hospital of Stomatology, Southwest Medical University from January 2014 to October 2015. CT scanning in axial, coronal, sagittal planes and three-dimensional reconstruction were performed routinely in all cases preoperatively. Digital model was designed by 3D printing technology according to the CT data. Individualized titanium mesh was shaped based on the digital model and used to repair orbital fracture. The accuracy of the reconstructed orbit was assessed based on the postoperative CT scan.RESULTS AND CONCLUSION: Postoperative CT scans showed that the implanted individualized titanium meshes were capable of accurately reconstructing the fractured orbit in all the 12 patients, and there was no infection, and titanium mesh loosening, prolapse, and rejection. With healthy eyes as controls, 11 cases of eyeball retraction were corrected completely, and only 1 case was still under correction. Diplopia symptoms disappeared in the 8 of 9 cases, and relieved in the 1 of 9 cases. Seven cases of eye movement limitation recovered postoperatively. To conclude, the individualized titanium mesh has great accuracy to repair orbital fractures in patients without serious complications,which has achieved good clinical outcomes in the orbital reconstruction.

Objective: To investigate the expression of MDR1 and GFP in the human hematopoietic cells mediated by adeno-associated virus. Methods: The GFP gene was transferred into the human hematopoietic cells by AAV vectors and created strong visible fluorescence by purely molecular biological means. Using adeno-associated virus vectors, we have transferred human mdr-1 gene into human hematopoietic cells and investigated the drug resistence of human hematopoietic cells modified with mdr-1 gene. PCR analysis confirmed that mdrl cDNA had been successfully transferred into the human hematopoietic cells. An assay of MTT proved that the human hematopoietic cells modified by mdrl gene had resistance to colchicine. Results: It was about 30% of the hematopoietic cells that expressed the green fluorescent proteins. The resistance of hematopoietic cells was increased parently when the cells were infected by the crude virus stocks. Conclusion: It is conducted that the AAV vector could successfully transfer the foreign gene into the human hematopoietic cells. The cells modified with mdrl gene have increased the resistance to drugs.
