BACKGROUND:Platelet-rich plasma (PRP) containing high levels of platelet-derived growth factor for knee osteoarthritis has achieved good clinical results;however, the effects of RPR on the repair of damaged articular cartilage are stil controversial.
OBJECTIVE:To study the effects of RPR on the repair of damaged articular cartilage in a rabbit model of knee osteoarthritis.
METHODS:The model of osteoarthritis in the rabbit right knee was established by Hulth’s method. Autologous PRP (0.5 mL) (PRP group), sodium hyaluronate (0.5 mL) (sodium hyaluronate group), and normal saline (model group) were injected into the right knee joint cavity, respectively. The morphology of articular surface and nitric oxide contents in knee joint fluid were observed and determined at 8 weeks after surgery.
RESULTS AND CONCLUSION:The morphology of articular cartilage in the PRP group was better than that in the other three groups. Mankin scores of articular cartilage and nitric oxide contents of knee joint fluid in the PRP group were significantly decreased compared with the model and sodium hyaluronate groups that in (P<0.05), while increased compared with the sham-operation group (P<0.05). Our results suggest that repair effects of PRP on the damaged articular cartilage are superior to sodium hyaluronate treatment.

Objective To investigate the treatment mechanism and effect of platelet-rich plasma(PRP) in treating rabbit knee osteoarthosis(KOA).Methods Thirty-two New Zealand adult clean class rabbits were randomly divided into the blank control group(A),model control group(B),PRP treatment group(C) and sodium hyaluronate treatment group(D).The group A conducted the simulated model construction,while the group B,C and D established the KOA rabbit model by using the Hulth method.After establishing the animal model,the group C was given PRP 0.5mLl by knee articular cavity injection,once every 3 weeks,twice in total;the group D was given sodium hyaluronate by knee articular cavity injection,once per week for 5 continuous weeks.The group A and B were injected with equal amount of normal saline at the same time point in the group C.The histological structure of articular cartilage,cell number,integrity of tidal line,and toluidine blue staining were observed by common optical microscope.The differences of Mankin′s scores were compared among various groups.The proper amount of knee joint fluid was collected for measuring the arachidonic acid expression in each group.Results The structure and morphology of articular cartilage in the group A were normal without obvious damage,while which in the group B,C and D had different degrees of damage,especially the cartilage structure in the group B had greater changes.Although the group B and C had the morphological and structure change of articular cartilage,but which was close to the cartilage structure in the group A.The Mankin′s score in the group A was lowest,while which in the group B was highest,which in the group C and D was significantly decreased after intervention treatment;the difference between the group B with the group C and D had statistical significance(P<0.05).The difference between the group C and D had statistical significance(P<0.05).The arachidonic acid level in the group A was lowest and which in the group B was highest,which in the group C and group D ranged between the group A and B,moreover the group C was lower than the group D (P<0.05).Conclusion PRP has obvious therapeutic and alleviated effect in treating KOA.

BACKGROUND: As a minimally invasive technology, percutaneous vertebroplasty is a safe and effective treatment for osteoporotic vertebral compression fractures.OBJECTIVE: To overview the research progress concerning the biomechanical properties, bone strength maintenance, bone absorption and degradation of bone filling materials used in percutaneous vertebroplasty.METHODS: The first author conducted a computer-based retrieval of CNKI, PubMed and Medline databases for relevant articles published from January 2005 to May 2016. The keywords were bone cement, bone filling materials, percutaneous vertebroplasty in English and Chinese, respectively.RESULTS AND CONCLUSION: Polymethyl methacrylate is not an ideal material for osteoporotic vertebral compression fractures. Calcium phosphate cement and calcium sulfate cement can replace the traditional polymethyl methacrylate; however, some problems still exist, such as poor effect of venography, incontrollable biological degradation rate, and lack of the evidence-based medicine about its long-term effect. Composite bone cement, as a good bone repair material, holds the advantages of various bone cements. As the composite bone cement has just been introduced in clinical practice, its long-term curative efficacy needs to be further studied.

OBJECTIVETo compare the differences in the clinical efficacy on Alzheimer's disease between acupuncture and medicine.

METHODSOne hundred and forty-one patients were randomized into an acupuncture group (72 cases) and a medicine group (69 cases). In the acupuncture group, the needling technique for benefiting qi, promoting blood circulation, regulating mind and improving intelligence was used at Shenting (GV 24), Baihui (GV 20), Fengchi (GB 20), Wangu (GB 12), Danzhong (CV 17), Zhangwan (CV 12), Qihai (CV 6), Xuehai (SP 10) and Zusanli (ST 36). The supplementary acupoints were selected according to the symptoms and physical signs. Acupuncture was given once a day and 6 treatments were required for a week. In the medicine group, the choline sterase inhibitor, donepezil (aricept) was prescribed for oral administration, 1 tablet (5 mg) each time, once every night. Four weeks later, the dose was increased to 2 tablets (10 mg) each time. In the two groups, the treatment of 4 weeks made one session and 4 sessions were required. The changes of scores before and after treatment in the minimum mental state examination (MMSE), the activity of daily living scale (ADL), Alzheimer's disease assessment scale-cognition (ADAS-cog) and the digit span (DS) were observed.

RESULTSAfter treatment, scores of MMSE and DS were increased as compared with those before treatment (both P < 0.05) and scores of ADL and ADAS-cog were reduced as compared with those before treatment. The score differences in MMSE, ADL, ADAS-cog and DS before and after treatment were significant in the two groups (all P < 0.01).

CONCLUSIONThe needling technique for benefiting qi, promoting blood circulation, regulating mind and improving intelligence significantly improves the overall function, cognition and activity of daily life in the patients of Alzheimer's disease and the efficacy is better than donepezil.

OBJECTIVETo compare the effect of reinforcing Shen method (RSM) and activating blood method (ABM) in treating osteoarthritis (OA) at the molecular level.

METHODSThe physical and chemical characteristics of components from respective recipes of RSM and ABM, and network features of component-target interaction network were analyzed by computer simulation methods including chemical space, molecular docking, and biological network, etc.

RESULTSThe chemical components of RSM and ABM were scarcely scattered with larger overlapping. Among established networks, the distribution of network features was partially similar in RSM and ABM. The average target number correlated with each component was 1.86 in RSM and 2.11 in ABM respectively. Each average target number was respectively correlated with 4.46 compounds and 3.93 compounds, reflecting multi-component and multi-target actions.

CONCLUSIONComputer simulation could intuitively trace out similarities and differences of two different methods and their interaction with targets, which revealed that the compatibility of RSM and ABM could have broader protein targets and potential synergism at the molecular level.

AlM:To observe the changes of corneal endothelium after phacoemulsification cataract surgery in different types of cataract patients.
METHODS: Randomly selected age-related cataract, diabetic cataract and cataract of high myopia 30 eyes of 30 cases, respectively, in our hospital. All patients underwent phacoemulsification combined with intraocular lens implantation, corneal endothelial density and the percentage of hexagonal cells were measured by corneal endothelial cell instrument without touching before surgery and one week after surgery.
RESULTS: The difference of the preoperative corneal endothelial cell density and the percentage of hexagonal cells among three groups were not statistically significant (P>0. 05). One week after surgery, the cell density in three groups were respectively 2 496. 86 ± 298. 96/mm2 , 2 379. 51 ± 375. 13/mm2 , 2 425. 38 ± 312. 68/mm2 , the percentage of hexagonal cells were respectively ( 46. 20 ± 12. 03)%, (43. 44±13. 99)%, (44. 35±8. 13)%. Both the cell density and the percentage of hexagonal cells one week after surgery were lower than those before operation. There were significant difference in three groups ( P <0. 05). Both the measurements in diabetic cataract group and cataract of high myopia group after surgery were lower than those in age-related cataract group, the cell density and the percentage of hexagonal cells in diabetic cataract group were lower obviously compared with those in age- related cataract group and the difference was significant (P<0. 05).
CONCLUSlON:The tolerance of corneal endothelial cell to phacoemulsification cataract surgery is lower in cataract with diabetes and high myopia. Corneal endothelium should be assessed preoperatively and protected intraoperatively.
