Objective To describe the methods of treatment of fresh and old fractures of the elbow joint with internal fixation.Methods Ten cases of fracture of the elbow with complete records were reviewed; 9 of them were male and 1 female; 6 of them were Han people and 4 Tibetans. The average age was 31 years. Four cases had open fractures and 6 had closed fractures. Among the cases of open fractures, 3 were treated with routine debridement and internal fixation of the fragments or internal fixation plus advanced skin flaps. One was treated as closed fractures after wound healing. The 6 cases of closed fractures were treated with a single tension band wiring, tension band and screw fixation, or screw fixation. Results The mean duration of the follow up was 8 months. Fracture healing was seen at 3－ 4 months. The range of motion of fresh fractures of the elbow and forearm was  4.2° － 144.2° . The old fracture cases had the range of motion of  31.3° － 115° without restriction in pronation and supination. Conclusion The intra articular fracture of elbow joint must be treated with early surgery to attain anatomical reduction with firm internal fixation. Early functional exercise is also important for the recovery.

There are many kinds of the scaffolds of tissue engineered cartilage, including collagen, polylactic acid hybrid material, chitosan and decellular extracellular matrix. They all have biocompatibility, safety and stable physicochemical property, which indicate good application value in the field of tissue engineering. Moreover, the composite scaffolds are superior to simple scaffold. It is potential scaffold materials that developing into composite materials, biomimetic materials, modified natural materials, intelligent material and nano-technological materials.

BACKGROUND: The intraoperative blood loss of unicompartmental knee arthroplasty is lower than that of total knee arthroplasty, but the difference of postoperative occult blood loss between them has not been widely studied. OBJECTIVE: To compare the difference of occult blood loss between unicompartmental knee arthroplasty and total knee arthroplasty, and to analyze whether patients with preoperative anemia can also undergo unicompartmental knee arthroplasty without the risk of blood transfusion. METHODS: 148 patients with knee osteoarthritis treated in 904 Hospital of the Joint Service Support Force of Chinese PLA from January 2014 to December 2016 were selected. Among them, 58 cases underwent unicompartmental knee arthroplasty and 90 cases underwent total knee arthroplasty. Hemoglobin levels and hematocrit were measured before and 1, 4, 21 and 42 days after operation, and the occult blood loss and blood transfusion rate were calculated. The trial was approved by the Ethics Committee of 904 Hospital of the Joint Service Support Force of Chinese PLA (approval No. 2019-01-03). RESULTS AND CONCLUSION: (1) The hemoglobin level of unicompartmental knee arthroplasty group was higher than that of total knee arthroplasty group at 1 and 4 days after operation (P < 0.01). There was no significant difference in hemoglobin level between the two groups before operation and 21, 42 days after operation (P > 0.05). (2) Hematocrit in the unicompartmental knee arthroplasty group was higher than that in the total knee arthroplasty group at 1 and 4 days after operation (P < 0.01). There was no significant difference in hematocrit between the two groups before operation and 21, 42 days after operation (P > 0.05).(3) From day one to day four after surgery, there was no occult blood loss in the female of unicompartmental knee arthroplasty group, and the average occult blood loss in the male was 4 g/L. The average occult blood loss was 10 g/L in female and 7 g/L in male in total knee arthroplasty group. The occult blood loss in male and female in unicompartmental knee arthroplasty group was lower than that in total knee arthroplasty group (P < 0.05 or P < 0.01). (4) The blood transfusion rate was 0% in unicompartmental knee arthroplasty group and 4.4% in total knee arthroplasty group. In patients with preoperative moderate anemia (hemoglobin 60-89 g/L), there was no need for blood transfusion in unicompartmental knee arthroplasty group (n=3), but blood transfusion was needed in 2 of 6 patients in total knee arthroplasty group (33%). (5) The results showed that unicompartmental knee arthroplasty had obvious advantages over total knee arthroplasty in postoperative occult blood loss.

In pregnant women,positive rate of thyroid peroxidase antibody(TPOAb) is approximately 3%~10%.It is still controversial whether thyroid antibody positive rate is higher in women undergoing artificial assistant reproductive technologies.TAI might have a negative effect on pregnant outcome,which has been proved in different groups of women.Intravenous immunoglobulin,thyroxin replacement therapy and selenium therapy have been used for TAI intervention.More evidence is needed to demonstrate mechanism and evaluate effect for each therapy.

AIM: To observe the antifungal action of Huanglian Pikang tincture (HPT). METHODS: An anifungal experiment was performed in vitro. RESULTS: HPT had obvious antibacterial actions for the trichophyton rubrum, T. interdigital, epidermophyton floccosum, candida albicans and lessened the colonies (n=5, P

?AIM:To investigate the causes and characteristics of retinal detachment after vitrectomy.?METHODS: Retrospective analysis of patients in our hospital in recent 4a who underwent primary, standard, three -port pars plana vitrectomy ( PPV ) . Retinal detachment occurred in 24 eyes ( 23 cases ) , 24-67 years old, average 49.0±12.0 years old.There were male in 17 cases, female in 6 cases, 6 right eyes, 18 left eyes.?RESULTS:Eighteen (75%) eyes without any symptoms were found during a routine check, 6 eyes ( 25%) with decreased visual acuity or in front of shadow.It took 1-223d from PPV to retinal detachment, average 40.7 ± 54.2d, of which retinal detachment occurred in 10 (42%) eyes within 1wk, 14 (58%) eyes within 1mo.The direct cause of retinal detachment was new retinal break ( a total of 27 holes ) in 19 eyes, proliferative vitreoretinopathy ( PVR) in 4 eyes, 1 eyes with primary hole not closed.All retinal detachment were ultimately completely reset.?CONCLUSION: The occurrence of new retinal breaks is the main cause of retinal detachment after vitrectomy, attention should be paid to the early postoperative peripheral retinal examination;after a timely surgery, the retina can be reset.

BACKGROUND: Cartilage stent materials were abundant. With the development of preparation technique, structure, and surface modification technique, performance of materials were improved remarkably; thus, Integrated-repaidng defects of articular cartilage and subchondral bone required high stability of cartilage replacement materials.OBJECTIVE: To evaluate the effect of polyurethane/nano-hydroxyapatite+polyamide66 (PU/n-HA+PA66) biological composite material on repairing articular cartilage and subchondral bone.METHODS: Twenty dog models were randomly divided into 4 groups: porous PU/n-HA+PA66 implant group, compact PU/n-HA+PA66 implant group, n-HA+PA66 implant group and blank control group. The macroscopic and histological evaluations were performed at 4, 12, and 24 weeks postoperatively. The interfaces of biomaterial implants with articular cartilage were observed by scanning electron microscope.RESULTS AND CONCLUSION: After 12 and 24 weeks, bone tissue grew into lower layer materials. Porous PU was well fused with peripheral cartilage. At 24 weeks postoperatively, the porous PU was closely connected with surrounding articular cartilage than the compact PU, and the articular cartilage surrounding the compact PU degenerated obviously. PU/n-HA+PA66 had a similar structure with normal cartilage and subchondral bone and had remarkable effects on repairing defects of articular cartilage and subchondral bone.
