0.05) in VAS and ramsay scale, but side effects were significantly different in group B compared with those in group S. Conclusion: The analgesia efficacy of S is same as B in maxillofacial postoperation, but side effects are more significantly in group B, and group S is more safe and handy.

Objective To study the growth and development as well as reproductive capacity of CL Long Evans rats. Methods Eighty CL Long Evans rats(80 days old)were bred in a barrier system. A monogamous mating system is used to reproduce 5 litters. Their main indexes of growth and reproduction were determined. The body weight gain of 60 second litter rats were analyzed from day 20 to 100. Results The number and weight of the fetus, the weaning time weight per cote and per litter in the second litter were the highest, and the fifth litter was the lowest. The growth and development curve was the same as that announced by Taconic. Conclusion Long Evans rats have been confirmed suitable for continual reproduction for 4 litters and the second litter is the best one for mating.

Objective To study the effects of resveratrol against toxicity induced by arsenic trioxide in rats.Methods Arsenic trioxide was given to SD rats intraperitoneally for 4 weeks.Resveratrol was injected intraperitoneally to the animals 4 h before arsenic trioxide challenge at dose of 30,60,or 120 mg?kg-1?d-1.Four weeks later,the contents of malondialdehyde(MDA),superoxide dismutase(SOD),nitric oxide(NO),glutathione peroxidase(GSH-Px) in serum,lung,spleen,liver and brain tissues were measured.Results Compared with the normal control rats,arsenic trioxide challenge resulted in increases of NO and MDA contents in serum,lung,spleen,liver and brain tissues,and decreases of GSH-Px and SOD levels in the rats received arsenic trioxide only.Resveratrol significantly inhibited these changes induced by arsenic trioxide in rat serum,lung,spleen,liver and brain tissues in a dose-dependent manner.Conclusion Resveratrol can protect antiperoxidase activity and inhibit peroxide productions.

BACKGROUND: Femoral prosthesis malrotation will lead to various complications, such as femoro-tibial and patellofemoral instability, and maladjustment of patellar movement trajectory, further affecting the recovery of the knee function.OBJECTIVE: To evaluate the influence of the rotation angle of the femoral prosthesis on the knee joint function after total knee arthroplasty (TKA).METHODS: Totally 146 patients (186 knees) undergoing TKA in the Department of Joint Surgery, Zhenjiang First People's Hospital from January 2010 to January 2014 were selected. Afterwards, the femoral condyle torsion angle was measured on CT to evaluate the rotational position of the femoral prosthesis. According to the condyle torsion angle, all the patients were divided into three groups: normal group (n=74, extorsion angle 3°-intorsion angle 3°), intorsion group (n=15, intorsion angle > 3°) and group (n=58, extorsion angle > 3°). All the patients were followed up for 3 years.RESULTS AND CONCLUSION: (1) The order of the activity function score was as follows: the normal group > extorsion group > intorsion group (P < 0.05). The standard activity, free activity and senior activity scores were highest in the normal group, followed by the extorsion group, and lowest in the intorsion group (P < 0.05). However, the standing and walking scores, as well as the satisfaction and expected scores did not differ significantly among groups. (2) That is to say, the rotational position of the femoral prosthesis influences the long-term knee joint function after TKA, so we should pay attention to the femoral prosthesis malrotation.

OBJECTIVETo observe the effect of Wenyang Huoxue Lishui Recipe (WHLR) containing serum on the expression of cathepsin L (CatL) in puromycin aminonucleoside-induced injury of mouse glomerular podocytes.

METHODSMouse podocyte cells (MPCs) in vitro cultured were divided into the normal control group, the model group, the dexamethasone (DEX) group, 10% WHLR containing serum group, 20% WHLR containing serum group, the vehicle serum control group. MPCs in the normal control group were cultured at 37 degrees C culture solution for 24 h. 45 mg/L puromycin was acted on MPCs in the model group for 24 h. On the basis of puromycin intervention, 1 limol/L DEX was co-incubated in MPCs of the DEX group for 24 h; 10% or 20% WHLR containing serum was co-incubated in MPCs of the 10% WHLR containing serum group and 20% WHLR containing serum group for 24 h. The vehicle serum control group was also set up by incubating with WHLR containing serum alone for 24 h. The expression of CatL and its substrate Synaptopodin in podocytes were detected by cell immunofluorescence staining. FITC-conjugated phalloidin was used to stain F-actin. A cortical F-actin score index (CFS index) was designed to quantify the degree of cytoskeletal reorganization in cultured podocytes.

RESULTSCompared with the normal control group, the expression of synaptopodin significantly decreased and the expression of CatL significantly-increased in the model group. F-actin arranged in disorder, gradually forming pericellular F-actin ring. CFS index was obviously elevated (P < 0.01). Compared with the model group, the epression of synaptopodin increased, the expression of CatL decreased, and CFS index also decreased in the DEX group, 10% WHLR containing serum group, and 20% WHLR containing serum group (P < 0.05, P < 0.01). Compared with the DEX group, the expression of synaptopodin decreased in 10% WHLR containing serum group, CFS index also decreased in 20% WHLR containing serum group (P < 0.05).

CONCLUSIONSWHLR could up-regulate the expression of synaptopodin, down-regulate the expression of CatL, and alleviate cytoskeletal reorganization of F-actin. It was helpful to stabilize the cytoskeleton of F-actin and improve the merging of podocytes.

A large number of cancer-associated fibroblasts (CAFs) in tumor tissues create a favorable environment for the development of tumor. CAFs inhibit immune cells activation and viability by cytokine secretion, and CAFs prohibit drugs and immune cells infiltration by producing extracellular matrix to weaken cancer treatment efficacy. Regulating CAFs or overcoming CAFs barriers are new strategies for cancer therapy. Hence, designing nano-carriers for regulating CAFs to suppress tumor progression or promoting drug delivery to tumor site by overcoming CAFs barriers has attracted much attention. Therefore, this manuscript reviewed the recent progresses of nano-carriers for CAFs-targeting cancer therapies, in order to provide a reference for clinical cancer treatment.

Objective To evaluate the effect of spinal-epidural and epidural anesthesia for pain relief in labor. Methods Totally 6671 cases selected from pregnant women delivered from Aug. 2001 to Oct. 2004 in our hospital were reviewed retrospectively. All cases were divided into three groups,1482 cases in spinal-epidural group (combined epidural) and 1111 in epidural group (epidural) who received pain relief during labor; 4078 as control group without any pain relief during labor. Delivery method and maternal, fetal complications among three groups were compared. Results (1) Delivery methods were significantly different (P0.05) in postpartum hemorrhage and neonatal asphyxia between spinal epidural 4.3%(63/1482) 1.0%(15/1482), epidural 4.1%(45/1111),0.8%(9/1111), and control 3.9%(159/4078), 1.4%(56/4078). Conclusions Anesthetic pain relief in labor may reduce the CS rate, but increase the rate of forceps delivery. Pain relief is associated with arrested and prolonged active phase, prolonged second stage. However, pain relief in labor doesnot enhance the rate of postpartum hemorrhage and neonatal asphyxia.

OBJECTIVETo discuss the treatment strategy of acetabular fractures and unstable pelvic fracture of the hip and to evaluate its outcome.

METHODSRetrospective analysis of clinical data in 32 patients with unstable pelvic fracture and acetabular fractures from January 2007 to June 2013 were collected. There were 18 males and 14 females aged from 18 to 62 years old (means 38 years old). According to Tile classification of pelvic fracture, 11 cases were type B1, 8 were type B2.1, 7 were type B2.2, 3 were type C1.1, 2 were type C1.2, 1 was type C3. According to Judet-Letournel classification, anterior column fracture was in 1 case, transverse fracture in 8, transverse plus posterior wall fracture in 6, T-type fracture in 1, anterior column plus half transverse fractures in 5, double column fracture in 11. Other combined injuries were treated early, the surgical operation were performed after stable condition. The hip joint function and the fracture reduction were assessed during follow-up.

RESULTSThe operative time was from 1.8 to 6.5 hours (averaged 3 hours). Two fat patients' incision occurred in fat liquefaction and healed after dressing, no incision infection happened. Only 1 case was lost to follow-up, 31 patients were followed up with a mean time of 23 months (6 to 42 months). The healing time of pelvic fracture was from 8 to 18 weeks (averaged in 10.6 weeks). The hip function was evaluated according to the Matta and Tornetta standard postoperatively, the result was excellent in 15 cases, good in 14 cases, fair and poor in 1 case respectively. The Majeed score of the hip function was 83.65? 7.67, the result was excellent in 15 cases, good in 12 cases and fair in 4 cases. The healing time of acetabular fractures was from 8 to 16 weeks (averaged in 10.2 weeks). The fracture reduction was assessed by Matta standard, the result was excellent in 15 cases, good in 12 cases and fair in 4 cases. The heterotopic ossification was evaluated by Brooker standard, 4 cases were grade I, 1 case was grade II . There were no infection, nonunion and necrosis of the femoral head in all patients. The nerve damage symptoms in 5 patients disappeared during 4 to 6 months after operation.

CONCLUSIONPatients with unstable pelvic fractures and acetabulum fractures were in a critical condition early, using the concept of damage control to save lives in a timely manner. Grasp the operation time in the late treatment, acetabulum fractures reach anatomical reduction as far as possible, pelvic fractures are given priority to stable reconstruction. The operation order was fixed pelvic ring first, according to the condition to choose the appropriate surgical approach and fixed mode.
