Polydatin is a monocrystaline compound isolated from Polygonum cuspidatum Sieb. et Zucc. (Polygonaceae) with biological properties, such as anti-inflammation, anti-oxidative and nephroprotective effects. Increasing number of studies have demonstrated the protective effect of polydatin on renal ischemia reperfusion injury. However, the possible mechanisms of this protection are not fully elucidated. This study aimed to investigate the effect of polydatin on ischemia-reperfusion induced expression of toll-like receptor4 (TLR4) in rat renal tubular epithelia cells (NRK-52E), and analyze the mechanism of polydatin on TLR4 signal pathway. The cultured NRK-52E cells were incubated in three gas incubators for a period of 6 h at hypoxia and 24h at reoxygenation to simulate the ischemia-reperfusion injury in vitro. TLR4 mRNA level was analyzed by real-time-PCR, and the protein expression of TLR4 and NF-κB by Western blotting, while TNF-α and IL-1β proteins expressions were detected by ELISA. Polydatin downregulated I/R induced mRNA and protein expressions of TLR4, and decreased the protein expression of NF-κB, TNF-α and IL-1β. The TLR4 blocker partially antagonized the effect of I/R on NF-κB signaling, and such inhibitory effect was markedly enhanced by polydatin. In the present study, polydatin protects NRK-52E cells from I/R injury possibly by relieving the inflammatory response through regulation of TLR4/NF-κB signaling pathway.

BACKGROUND: As a micro-injurying and reduplicative treatment of osteoarthritis,the arthroscopic debridement has got the affirmation of numerous scholars. But as one of the standard procedures in artnroscopic debridement,synovectomy is called in question recently.OBJECTIVE: To explore the applied value of synovectomy in the arthroscopic debridement of osteoarthritis.DESIGN: Retrospective controlled analysis.SETTING: Department of Orthopaedics, Fushun Central Hospital.PARTICIPANTS: Sixty-five patients received synovectomy in the arthroscopic debridement of knee joint osteoarthritis in the Department of Orthopaedics,Fushun Central Hospital from February 1997 to December 2000.Thirty-two among them,with complete data and over 1 year's followup,were taken for synovectomy group. Forty-eight patients received the arthroscopic debridement of knee joint osteoarthritis without synovectomy in the Department of Orthopaedics,Fushun Central Hospital from January 2001 to November 2003.Thirty among them,with complete data and over 1 year's follow-up,were taken for control group.METHODS: Synovectomy was taken as the factor of intervention in the operation to perform grouping. The analysis of curative effect was performed to control with joint douching,corpus liberum removal,osteophyma cleaning,meniscus fitting,cartilage gouging,synovectomy and without synovectomy or part synovectomy. Lysholm evaluation standard of knee joint osteoarthritis was used to the knee joint functional evaluation beween preoperation and postoperative 1 year in two groups. And operative time,postoperative draining quantity,postoperative 7-day visual analog score,postoperative 1-year Lysholm score of knee joint, were recorded.MAIN OUTCOME MEASURES: Preoperative and postoperative 1-year Lysholm score of knee joint,operative time,postoperative draining quantity,postoperative 7-day visual analog score.RESULTS: Sixty-two patients were included and all of them entered the result analysis.The preoperative patients in two groups were comparable with each other and the differences of Lysholm score were not significant (t=0.127,P=0.899).The operative time was longer in synovectomy group than in control group,the differences were significant (t=9.547,P ＜ 0.001)and the postoperative draining quantity was more in synovectomy group.The postoperative visual analog score was bigger in synovectomy group than in control group and the differences were significant [the scores of synovectomy and control groups were respectively (4.6±1.1),(2.8±1.4),t=6.206,P ＜ 0.001].The differences of knee joint score in 1-year follow-up were not significant [the scores of synovectomy and control groups were respectively (77.6±11.9),(79.0± 10.3),t=0.562,P=0.576].CONCLUSION: Synovectomy can not increase the curative effect in the near future in the arthroscopic debridement of osteoarthritis. On the contrary,the operative time was longer,the operative wound was larger and postoperative reaction was more serious. It should not be used in the debridement generally.

Objective To assess the effectiveness of donepezil versus huperzine in the treatment of elderly patients with mild cognitive impairment (MCI).Methods Total 122 elderly patients with MCI were divided into two groups:donepezil treatment (5.0 mg once daily) (n=71) and huperzine treatment group (0.1 mg twice daily) (n=51).All the patients were followed up for 24 weeks.Before and 12 weeks,24 weeks after drug treatment,the cognitive functions were evaluated,including MMSE,MOCA,ADAS-cog,CDR,GDS,ADL,HIS and HAMD.Results There was no significant difference in age,sex,education time and neuropsychology rating scales between the groups before drug use.As compared with the score before drug use,the donepezil group showed a significant increase in MMSE after 12-weeks (t=4.47) or 24-weeks (t=6.16) (P＜0.01),a decrease in the score of ADAS-cog after 12-weeks (t=2.33,P＜0.05) or 24-weeks( t=3.68,P＜0.05),and an increase in the score of MOCA after 24-weeks drug use (t=2.56,P＜0.05).The huperzine group showed significant improvement in MMSE after 24-weeks drug use (t=2.80,P＜0.05),but there was no difference in other time points or in the score of MOCA and ADAS-cog as compared with the score before drug use.After 24 weeks' treatment,the donepezil group had higher MMSE (t=2.01,P＜0.05) and lower ADAS-cog (t=2.09,P＜0.05) scores than the huperzine group.30 patients (total effective rate was 42.3 ％) and 9 patients (total effective rate was 17.6 ％ ) became improved in donepezil and huperzine group,respectively,with significant difference (x2 =8.26,P＜0.01 ).There were 5 cases in the donepezil group and 3 cases in the huperzine group getting slight side-effects which disappeared by continuing to take drugs or by adjusting drug taking time.Conclusions Donepezil and huperzine as the cholinesterase inhibitors are effective and safe,and the efficacy of donepezil is faster and better in treating elderly patients with MCI.

Objective To investigate the curriculum construction and evaluation of teaching effectiveness of simulation and comprehensive experiment for clinical nursing. Methods Based on the investigation of hospital, taking working progress and working task of nurses as orientation, we constructed the curriculum of simulation and comprehensive experiment for clinical nursing, and unfold in junior class (before clinical practice) for student nurses. The teaching effect was evaluated. Results Unfolding simulation and comprehensive experiment could effectively enhance the nursing students' ability to transform theoretical knowledge into clinical nursing practice, and was favorable to change the role of nurses and improve the satisfaction degree of clinical practice.Conclusions Unfolding simulation and comprehensive experiment for clinical nursing for student nurses before clinical practice is practicable and essential.

OBJECTIVETo explore the effect of internal fixation with screw through femoral epiphyseal plate on growth in- hibition via an experimental study.

METHODSForty New Zealand rabbits were randomly divided into 4 groups and 10 rabbits in each group. Epiphyseal plate was injured by penetrating of screws, and the size of damage area was controlled by changing the number of threads. Group A: blank group; group B: injury area accounted for 4% of the epiphyseal plate; group C: injury area accounted for 6%; group D: injury area accounted for 8%. The internal fixation was removed after 2 weeks, and the results were observed with X-ray film for 4 groups to judge the complications such as early closure of epiphyseal.

RESULTSIn each group, there were no statistical differences in the length of the femoral neck, the diameter of femoral neck, the diameter of the femoral head, and the epiphyseal plate closure time. The growth speed of the length and diameter of the femoral neck, as well as the diameter of femoral head, were quicker on the early phase, and the speed was slowest when the epiphyseal plate was being closed.

CONCLUSIONThe injury area of epiphyseal plate under 8% is safe for its growth. Because no evidences demonstrate the growth inhibition of epiphyseal plate, the screws can be used for rabbit epiphyseal plates.

BACKGROUND: As a blood concentrate rich in growth factors and fibrin, platelet-rich fibrin (PRF) is able to significantly promote bone regeneration. PRF mixed with bone substitutes is commonly used to repair bone defects in oral maxillofacial region. But it remains controversial whether PRF as a sole material in sinus floor elevation can produce enough new bone tissues.OBJECTIVE: To evaluate the osteogenic potential of PRF as a sole grafting material in sinus floor elevation by means of an animal model.METHODS: Twelve healthy adult mongrel dogs aged 12-18 months were selected and randomized into three groups (groups A, B and C), with four dogs in each group. Upper first molars on both side of each dog were extracted 12 weeks prior to sinus floor elevation and simultaneous implants placement. Different materials were used to fill in the space between the sinus membrane and implant. Groups A, B and C were filled with PRF, autologus bone particles and autologus blood clot respectively. After 12 weeks, specimens were harvested to analyze the new bone formation by gross observation, X-ray examination and histological evaluation.RESULTS AND CONCLUSION: New bone formation was found to embrace all the implants close to the bony sinus floor, and the tips of all implants were free from bone coverage. The new bone height of groups A, B and C were (3.135±0.288),(3.218±0.345), and (1.898±0.157) mm, respectively. The new bone density of groups A, B and C were (65.06±5.88),(75.34±8.18), and (56.92±4.95) g/cm3, respectively. There were significant differences between the new bone height in groups A and C as well as in groups B and C (P < 0.05). Also, significant differences were found between the new bone density in groups A and B, B and C, A and C (P < 0.05). Within the confine of this experiment, it is feasible to use PRF as a sole grafting material in the sinus floor elevation to generate new bone, but the new bone volume is limited.

Objective To investigate the time for spontaneous closure of the ductus arteriosus and the trends of cardiac index(CI),peripheral vascular resistance index(SVRI)and blood pressure of neonates with different gesta-tional ages(GA). Methods A prospective observational study about 95 newborns,including 20 full - term and 75 pre-term infants were divided into 4 groups according to their GA as GA ﹤ 32 weeks(n = 27),32 weeks≤GA ﹤ 34 weeks (n = 25),34 weeks≤GA ﹤ 37 weeks(n = 23),GA≥37 weeks(n = 20). Patent ductus arteriosus was diagnosed by echocardiography(ECHO)at the time of 24 h,48 h,72 h,7 d and 14 d. CI,SVRI and blood pressure were measured with ultrasonic cardiac output monitor(USCOM). Results The cumulative spontaneous closure rate of arterious ductus of 32 weeks≤GA ﹤34 weeks,34 weeks≤GA ﹤37 weeks group and GA≥37 weeks group at 24 h after birth was 44. 0% , 61. 0% and 90. 0% respectively. However the rate was only 59. 1% at 72 h with the GA less than 32 weeks,of which 9 cases needed ibuprofen and 1 patient was conducted ductus arteriosus ligation. The differences in cumulative closure rate among 4 groups based on GA at 5 time points were statistically significant(χ2 =6. 756,4. 735,18. 890,11. 366,28. 159,all P ﹤0. 05). There was significant increase of systolic blood pressure,diastolic blood pressure and SVRI with ductus arte-riosus closure(t = -32. 561,-19. 913,-31. 791,4. 760,all P ﹤0. 000 1;t = - 25. 091,- 23. 400,- 21. 147,2. 240,all P ﹤0. 05;t = -10. 931,-9. 975,-9. 629,2. 350,all P ﹤ 0. 05). Whereas CI significantly decreased in groups of GA ﹤32 weeks,32 weeks ≤GA ﹤34 weeks,34 weeks ≤GA ﹤37 weeks(t =9. 224,6. 515,5. 996,all P ﹤ 0. 001)and no sig-nificant changes in GA≥37 weeks(t =0. 940,P ﹥0. 05). Conclusions With the increase of gestational age,the rate of naturally early arterial catheter closure is higher. Whereas there still are nearly one - third infants requiring medical or surgical intervention in the group of GA ﹤32 weeks. Ductus arteriosus has great influence on hemodynamics. For preterm, especially very low birth weight preterm,the use of ECHO and USCOM can early detect and treat patent ductus arteriosus.
