Objective To explore the case management model of return to work injured workers. Methods A retrospective cohort wasformed with 523 injured workers in rehabilitation centre. The social demographic information, medical data and intervention process wereextracted from the medical records. A Cox Regression Model was used to examine the effect of case management on work processes and otherrelevant factors affecting RTW. Results 275 cases (82.1%) out of the 335 subjects successfully returned to work after median absence durationof 36.0 days. Computer training prompted RTW outcomes (P<0.01), while disability adjustment activity showed an opposite effect(P<0.05). It showed that education level, family attitude to RTW and level of injury were significantly associated with outcomes of RTW.Conclusion Specific skills reconstruction and training would is one of the most important components of the case management interventionprogram on RTW. Although disability adjustment did not specifically benefit RTW, it might help in improving workers' general health status,and it should not be ignored in any case.

BACKGROUND:Peridental membrane distraction osteogenesis exerts the functions at peridental membrane and leads to tooth movement. Alveolar bone distraction osteogenesis produces tooth movement through the displacement of the whole bone plate.
OBJECTIVE:To establish three-dimensional finite element model of upper and lower jaw of healthy adults under three different conditions, and to compare the stress distribution and distal movement of the models using three-dimensional finite element analysis method.
METHODS:Model 1:three-dimensional finite element model of the canine under normal conditions using a
variety of software;Model 2:three-dimensional finite element model of the canine after distracting osteggenesis of the periodontal ligament;Model 3, three-dimensional finite element model of the canine after reducing resistance and distracting osteggenesis of the alveolar bone. The force loadings were stimulated among these models.
RESULTS AND CONCLUSION:The biggest displacements on those three models occurred in canine crown on 1/3, and the displacement quantity on canine was model 2>model 3>model 1. The biggest equivalent stress concentrated in distal alveolar crest, and the equivalent stress was model 2

Objective To analyze the clinicopathologic characteristics and treatment of primary and secondary bladder mucosa lymphoma. Methods From June 1996 to September 2011,8 cases of bladder mucosa lymphoma patients including primary bladder mucosa lymphoma patients (2 males and 3 females)and secondary bladder mucosa lymphoma patients ( 1 male and 2 females) were treated in our institute.The patient's mean age was 68 years (ranged from 57 to 78 years),and the other 3 secondary bladder mucosa lymphoma patient's mean age was 61 years (ranged from 41 to 81 years).7 of 8 patients accepted transurethral resection of bladder tumor combined with CHOP chemotherapy and radiotherapy,and 1 patient abandoned treatment.CHOP chemotherapy and radiotherapy were performed at 2 weeks post-operatively.Secondary bladder mucosa lymphoma patients accepted 3-dimensional conformal 6000 cGy radiotherapy.Urinary CT examination showed that there were round or oval irregular tumors in the wall of urinary bladder,whose diameters were 1 to 4 cm.Tumor edges were glossy and tumor density were uniform.In addition,the bladder wall with tumor was uneven.In contrasted CT,the tumors appeared obviously enhanced.7 cases had cauliflower-like tumors found by cystoscope,and there were necrosis-calcification area in the center of tumors.1case appeared multiple tumors,which consisted of one big tumor and three smaller ones. Results There were 5 cases of primary bladder mucosa lymphoma, including 3 bladder mucosa associated lymphoma (MAL) cases and 2 diffuse large B cell lymphoma cases.There were 3 secondary bladder mucosa lymphoma cases including 2 diffuse large B cell lymphoma cases and 1 generalized follicular cystic central lymphoma case,which belongs to the tuberous sclerosis Hodgkin lymphoma.Immunohistochemical analysis showed that CD20,CD21,CD43 staining were positive in low grade MAL (3 cases).However,CD3,CD20,CD31 staining were positivein high grade MAL (5 cases). All patients were followed up 3 to 44 months.3 cases of secondary malignant lymphoma patients died after diagnosed after 3 to 13 months.5 cases of primary malignant lymphoma patients were all survived. 1 case recurred 14 months after surgery and accepted TURBT and CHOP chemotherapy again.Pathologic diagnosis showed the transformation from peripheral zone of bladder mucosa associated lymphoma to diffuse large B cell lymphoma.The patient was free of recurrence. Conclusions MAL and diffuse large B cell lymphoma are the most common type of bladder mucosa lymphoma.Primary and secondary diffuse large B cell lymphoma have similarities in histological analysis,but the former prognosis is better than the latter's. Transurethral resection of bladder tumor combined with chemotherapy and radiotherapy can prevent the relapse of MAL in short term and long term with good tolerance,and can be used as ideal treatment of MALT.
4.Study on anti-coagulant property of radio frequency sputtering nano-sized TiO2 thin films.
Journal of Biomedical Engineering 2010;27(6):1303-1306
Nano-TiO2 thin films were prepared by Radio frequency (RF) sputtering on pyrolytic carbon substrates. The influences of sputtering power on the structure and the surface morphology of TiO2 thin films were investigated by X-ray diffraction (XRD), and by scanning electron microscopy (SEM). The results show that the TiO2 films change to anatase through the optimum of sputtering power. The mean diameter of nano-particle is about 30 nm. The anti-coagulant property of TiO2 thin films was observed through platelet adhesion in vitro. The result of experiment reveals the amount of thrombus on the TiO2 thin films being much less than that on the pyrolytic carbon. It also indicates that the RF sputtering Nano-sized TiO2 thin films will be a new kind of promising materials applied to artificial heart valve and endovascular stent.

Objective To observe the therapeutic effect of Yougui Pills and its separate formula for the treatment of kidney-yang deficiency syndrome. Methods A total of 60 patients of kidney-yang deficiency syndrome were randomly divided into treatment group and control group, 30 cases in each group. Treatment group was treated with Yougui Pills, and the control group was given the separate formula from Yougui Pills which had the actions of warming kidney yang. Four weeks constituted one treatment course and the treatment covered 2 courses. The changes of major clinical symptom scores, total effectives rate and associated indexes such as peripheral white blood cells, serum antibodies, and complements were compared between the two groups following the treatment for 8 weeks. Results The total effective rate, and improvement of major clinical symptoms and the peripheral white blood cells in the treatment group were superior to those in the control group ( P<0.05 or P<0.01) . However, there were no significant differences of the levels of serum antibodies and complements between the two groups (P>0.05) .Conclusion Yougui Pills show better effect than its kidney-yang-warming separate formula for the treatment of kidney-yang deficiency syndrome, indicating that the method of generating yang by activating yin is superior to the method of simply nourishing kidney yang.

OBJECTIVETo discuss the surgical method and clinical efficacy for open tarsometatarsal joint injuries.
METHODSFrom March 2011 to January 2015, 21 patients with open tarsometatarsal joint injuries were treated with stage-surgery method, including 14 males and 7 females with an average age of 45.6 years old ranging from 20 to 75 years. Injury site occurred in the left foot of 13 cases and right foot of 8 cases. Traffic injury was in 5 cases, crush injury in 6 cases, heavy crushing was in 10 cases. According to Myerson to classify for tarsometatarsal joint injury, 5 cases were type B2, 9 cases were type C1, and 7 cases were type C2. And according to Gustilo to typing for soft tissue injury, 5 cases were type IIB, 10 cases were type IIIA, 6 cases were type IIIB. Fracture healingand complications were observed after operation and clinical effects were evaluated according to the midfoot score of AOFAS.
RESULTSAll the patients were followed up from 11 to 40 months with an average of 16.2 months. The fracture healing time was from 10 to 16 weeks with an average of 12.3 weeks. No complications such as deep infection, nonunion and osteomyelitis were found. Midfoot score of AOFAS at last follow-up was 83.0±14.9, 9 cases got excellent results, 8 good, 2 fair, 2 poor. Two patients complicated with severe traumatic arthritis once again underwent tarsometatarsal arthrodesis.
CONCLUSIONSFor the treatment of open tarsometatarsal joint injury, reasonable debridement, comprehensive assessment for the soft tissue injury, correctly grasp the surgical indications and time of internal fixation, can reduce the incidence of deep infection and osteomyelitis.

Objective:
To investigate the clinical effect of a novel disposable ring versus that of the suture device in circumcision for redundant prepuce and phimosis.
METHODS:
We randomly assigned 470 male patients with redundant prepuce or phimosis to receive circumcision with a novel disposable ring (the DR group, n = 235) or the suture device (the SD group, n = 235) and compared the operation time, intraoperative blood loss, pain scores, wound healing time, and postoperative complications and penile appearance between the two groups of patients.
RESULTS:
All the operations were completed smoothly. Compared with the SD group, the DR group showed significantly shorter operation time ([7.49 ± 1.84] vs [3.83 ± 0.42] min, P <0. 05), less intraoperative blood loss ([3.34 ± 2.59] vs [2.41 ± 1.01] ml, P <0.05), lower intraoperative pain score (0.57 ± 0.76 vs 0.20 ± 0.47, P <0.05) and 6-hour postoperative pain score (3.42 ± 1.12 vs 0.48 ± 0.94, P <0.05), shorter wound healing time ([12.05 ± 2.80] vs [7.79 ± 1.65] d, P <0.05), lower incidence rates of postoperative glans congestion or edema (36.17% [85/235] vs 2.56% [6/235], P <0.05), dysuria or strenuous urination (34.04% [80/235] vs 2.13% [5/235], P <0.05) and bleeding or hematoma (5.11% [12/235] vs 1.28% [3/235], P <0.05), and higher satisfaction with postoperative penile appearance (90.6% [213/235] vs 95.8% [228/235], P <0.05). There were no statistically significant differences between the SD and DR groups in the pain scores at the sixth night after operation (1.31 ± 0.96 vs 1.34 ± 1.07, P >0.05) or while the staples scraping the underpants or at the ring removal (3.49 ± 1.22 vs 3.36 ± 1.41, P >0.05). No obvious postoperative infection or delayed healing was observed except for 3 cases of wound dehiscence (1 in the DR and 2 in the SD group) and 8 cases of delayed removal of the staples in the SD group.
CONCLUSIONS
The novel disposable ring, with its advantages of short operation time, less bleeding and pain, good penile appearance, high safety, and simple operation, is obviously superior to the suture device in circumcision and deserves to be applied and popularized clinically. .

Objective:
To compare the clinical effect of a novel disposable circumcision device Ring with that of conventional circumcision in the treatment of redundant prepuce and phimosis.
METHODS:
Totally, 750 patients with redundant prepuce or phimosis underwent Ring circumcision (group A, n = 450) or conventional circumcision (group B, n = 300). We recorded the operation time, intraoperative blood loss, Visual Analogue Scale (VAS) intraoperative pain scores, postoperative complications, wound healing time, and patients' satisfaction with postoperative penile appearance, followed by comparison of the collected data between the two groups of patients.
RESULTS:
All the operations were successfully completed. Group A, as compared with B, showed significantly shorter operation time ([3.78 ± 0.42] vs [26.24 ± 3.99] min, P <0.05), less intraoperative blood loss ([2.39 ± 1.01] vs [10.80 ± 3.57] ml, P <0.05), lower pain scores intraoperatively (0.14 ± 0.36 vs 2.30 ± 1.46, P <0.05), 6 hours postoperatively (0.32 ± 0.78 vs 3.03 ± 1.56, P <0.05) and at the ring removal (3.35 ± 1.42 vs 2.78 ± 1.43, P <0.05), shorter wound healing time ([7.61 ± 1.60] vs [8.57 ± 1.37] d, P <0.05), higher satisfaction with postoperative penile appearance (97.8% [440/450] vs 86% [258/300], P <0.05), and lower incidence of postoperative bleeding or hematoma (0.89% [4/450] vs 3% [9/300], P <0.05). No statistically significant differences were observed between groups A and B in the nocturnal pain score before the ring removal (1.45±1.02 vs 1.38 ± 0.92, P >0.05) or the postoperative incidence rate of edema (0.89% [4/450] vs 2.33% [7/300], P >0.05). There were no significant postoperative infections or delayed incision healing except for 1 case of wound dehiscence in each group.
CONCLUSIONS
Ring circumcision, with its advantages of shorter operation time, less blood loss and pain, higher safety, and better postoperative penile appearance, is easily accepted by the patients and deserves wide clinical application.
