When adult developmental dysplasia of hip (DDH) patients have developed secondary os- teoarthritis of hip (OAH) with serious clinical symptoms,total hip replacement (THR) is their first choice of treatment.The anatomic structures of the acetabulum and femur in these patients are ahnormal and special,such as small and shallow cup,small femoral head,and narrow medullary cavity at proximal femoral shaft.As a result,the THR for DDH patients is quite different from the conventional ones and is thus highly difficult.We review in this paper the clinical classification of DDH,which is important for its treatment,the difficulties we will have in THR, especially in acetabular reconstruction and femoral prosthesis placement,and also strategies to resolve them.

BACKGROUND: At present, more and more scholars pay attention to the influence of spine and pelvis sagittal balance on the quality of life of patients. Postoperative changes in spine imaging parameters fol owing corrective osteotomy for lumbar degenerative kyphosis have not been reported. OBJECTIVE: To evaluate postoperative changes in sagittal balance fol owing corrective osteotomy for lumbar degenerative kyphosis. METHODS: We retrospectively analyzed 35 consecutive lumbar degenerative kyphosis patients treated with posterior osteotomy fixation in the First Affiliated Hospital of Xinjiang Medical University from February 2012 to December 2014. Imaging parameters were measured before fixation, immediately after fixation and during final fol ow-up. RESULTS AND CONCLUSION: (1) There were significant differences between preoperative and postoperative parameters except for pelvic incidence angle (P < 0.05). (2) There were significant differences between postoperative and last fol ow-up parameters except for Cobb angle, pelvic incidence angle, thoracic kyphosis angle and the thoracolumbar kyphosis (P < 0.05). (3) Pelvic tilt angle was negatively correlated with lumbar lordosis after fixation (r=-0.610, P < 0.001). Thoracic kyphosis was positively correlated with lumbar lordosis (r=0.598, P < 0.001). (4) Results suggested that lumbar sagittal contour can be significantly improved by corrective osteotomy for lumbar degenerative kyphosis. Simultaneously, reciprocal changes in the adjacent areas such as thoracic spine and pelvis occur to adapt to the new sagittal balance.

Objective To study the efficacy and indications of percutaneous radiofrequency ablation (PRFA) for small primary liver cancer(SPLC). Methods The clinical data of 16 patients with SPLC treated by PRFA were analysed retrospectively. Results The diameter of tumor in all 16 patients were ≤3cm. After PEFA, AFP from postive returned to negative in 93.3% of patients; and BUS and CT showed the tumors shrinking with capsule formation. The 0.5,1,2-year survival rate were 93.8%,100%,100% respectively. Conclusions PRFA for SPLC has advantages such as minitrauma, safe and effective, especiolly suitable to the patients with contrainsications of operation, or the tumor locating to the deep position of liver, or around inferior vena cava, hepatic veins or hepatic porta etc.

Objective To evaluate the usage of renoportal anastomosis in the liver transplanta- tion.Method The successful experience about renoportal anastomosis for portal vein reconstruction in liver transplantation was reported,and related literature reviewed.Results Including our case,there have been 13 cases of liver transplantation using renoportal anastomosis for portal vein reconstruction. Among these patients,8 cases were complicated with diffuse portal vein thrombosis,and 10 cases had a splenorenal shunt(spontaneous shunt in 3 and surgical shunt in 7).Complications related to portal vein hypertension occurred in 3 cases(transient ascites in 2 cases and severe digestive bleeding in 1 case)after liver transplantation.There were 3 deaths which were not related to renoportal anastomo- sis.Conclusion Renoportal anastomosis is a safe and feasible technique in liver transplantation for the patients with diffuse portal vein thrombosis or with splenorenal shunt(spontaneous or surgical shunt).

OBJECTIVETo study the blood enriching effects of Paeoniae Radix Rubra and Paeoniae Radix Alba, paeoniflorin and albiflorin on mouse model of blood deficiency caused by γ-ray radiation.

METHODBuild mouse model of blood deficiency induced by γ-ray radiation. Paeoniae Radix Rubra and Paeoniae Radix Alba were given during modeling. The amount of WBC was detected af- ter the treatment. Based on the result of WBC and paeoniflorin content, albiflorin content in Paeoniae Radix Rubra and Paeoniae Radix Alba, the same model and the same method were used to comparatively study the effect of blood enriching of paeoniflorin and albiflorin.

RESULTOn the 7th day, the amount of WBC in model mice treated with 2 g x kg(-1) Paeoniae Radix Alba and 2 g x kg(-1) Paeoniae Radix Rubra significantly increased compared with that of model group (P < 0.05). In another experiment with the same model, the amount of WBC in model mice treated with 120 mg x kg(-1) paeoflorin and 120 mg x kg(-1) albiflorin significantly increased (P < 0.05) compared with that of model group on the 7th day. On the 10th day, the amount of WBC in rats treated with 120 mg x kg(-1) paeoflorin increased significantly (P < 0.05) compared with that of model group. Compared with the same dose of paeoniflorin, the amount of WBC in mice treated with albiflorin had no significant difference.

CONCLUSIONAll Paeoniae Radix Alba, Paeoniae Radix Rubra, paeoniflorin and al- biflorin can raise the amount of WBC and have the effect of enriching blood induced by radiation, while paeoniflorin and albiflorin have a similar result in this model. The result indicated that both paeoniflorin and albiflorin are effective constituents in Paeoniae Radix Alba, and paeoniflorin work as the common effective constituent in both Paeoniae Radix Rubra and Paeoniae Radix Alba.

Objective To observe the effects of vaporized perfluorocarbon (PFC) combined with exogenous pulmonary surfactant (PS) inhalation on rabbit models of acute lung injury (ALI).Methods Thirty-two New Zealand rabbits were randomly divided into four groups: ALI group, combination treatment group, PFC group, and PS group (each groupn = 8 rabbits). The rabbit model of ALI was induced by the whole lung normal saline lavage. After modeling, in the combined group, 3 mL/kg vaporized perfluorooctyl bromide/dipalmitoylphosphatidylcholine (PFOB/DPPC) emulsion was inhaled, the rabbits in PFC and PS groups were treated with vaporized PFOB emulsion and vaporized DPPC emulsion 3 mL/kg inhalation respectively, and in the ALI group was given the same amount of vaporized normal saline inhalation. In each group, before modeling for 30 minutes (basic value), after modeling for 1 hour and after treatment at 0 minute, 30 minutes, 2 hours, 4 hours, the respiratory rate (RR), oxygenation index (OI), dynamic lung compliance (Cdyn) were observed, and the lung coefficient (LI) and lung permeability index (LPI) were calculated; the levels of serum tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were measured by double antibody sandwich enzyme-linked immunosorbent assay (ELISA); the lung tissue was collected and the lung pathological changes were observed under macroscopic and microscopic observation.Results Aftermodeling, the levels of OI, Cdyn were quickly lowered, RR became significantly elevated, and there were obvious edema, hemorrhage and exudation in lung tissue of ALI group. The levels of OI were significantly increased in combined group and PFC group compared with the level in ALI group after treatment at 0 minute initially [mmHg (1 mmHg = 0.133 kPa): 231.0±16.7, 221.4±19.0 vs. 189.5±21.0, both P < 0.05], while the level of OI in PS group was increased significantly until 4 hours after treatment, being higher than that in ALI group (mmHg: 297.0±20.7 vs. 243.3±36.7,P < 0.05); RR was decreased significantly in combined treatment group at 30 minutes after treatment compared with that in ALI group (bpm: 151.1±13.3 vs. 178.5±32.0,P < 0.05), while the RR in PFC group and PS group were not increased significantly until 4 hours after treatment being higher than that in ALI group (bpm: 129.3±14.3, 133.1±13.9 vs. 157.5±32.5, bothP < 0.05). Compared to ALI group, the three treatment groups resulted in significant improvement in Cdyn right at 0 minute (mL/cmH2O: 1.64±0.10, 1.45±0.10, 1.43±0.09 vs. 0.57±0.05, allP < 0.05), their LPI, LI and inflammatory cytokines were significantly decreased [LPI (×10-5): 4.21±0.42, 4.76±0.55, 4.87±0.49 vs. 5.56±0.52, LI: 8.04±0.58, 8.90±0.88, 9.22±0.71 vs. 10.85±0.73, TNF-α (ng/L): 50.05±4.91, 56.18±5.54, 63.60±5.96 vs. 73.60±5.27, IL-1β (ng/L): 34.27±4.55, 40.29±5.03, 48.13±6.38 vs. 54.71±4.26, allP<0.05], and pulmonary edema, congestion and inflammatory cell infiltration were obviously ameliorated (pathological scores: 3.74±0.58, 4.50±0.75, 5.29±0.72 vs. 6.13±0.72, P < 0.05). Cdyn levels were increased significantly in combined treatment group at 0 minute, 30 minutes, 4 hours after treatment compared with thosein PFC and PS group, but there were no significant differences between PFC and PS group. Levels of LI, LPI, inflammatory factors and pathological scores were decreased significantly in combined treatment group compared with those in PFC and PS group, the degrees of improvement of inflammatory factors and pathological scores in PFC group were more obvious than those in PS group (allP < 0.05).Conclusions PFOB combined with DPPC inhalation can provide greater oxygen delivery, reduce the pro-inflammatory cytokines, supplement PS and influence its distribution on the surface of lung, which might lead to a marked and sustained improvement in oxygenation, pulmonary function and amelioration of lung edema and inflammatory reaction in saline lavage induced lung injury of rabbits.

OBJECTIVETo study the protective effect of Acai berries(Euterpe oleraceae) on chronic alcoholic hepatic injury in rats and their mechanism.

METHODWistar rats were fed for 1 week and randomly divided into blank group, model group, Dongbao Gantai group, Acai 1.6, 0.8, 0.4 g . kg-1 groups. The blank group was given distilled water, and the other groups were orally given 56% white spirit (Erguotou) for eight weeks at the dosages of 8 mL . kg-1 in the 1st week, which increased by 0.1 mL week by week till to 15 mL . kg-1, in order to establish the chronic hepatic injury model, and observe the effect of Acai berry freeze-dried powder on hepatocyte membrane permeability, liver lipid peroxidation, changes in inflammatory cytokines and pathological changes in hepatocytes.

RESULTAcai berries could significantly reduce serum ALT and AST(P<0.05), MDA(P<0.05), TG(P<0.05) and serum TNF-α and IL-6(P <0.05) and increase GSH and SOD(P <0.05). According to liver histopathological observation, livers in the model group were dominated by steatosis, some livers suffered spotty necrosis and inflammatory cell infiltration; The positive drug and Acai groups showed different changes in pathologic changes in rat livers.

CONCLUSIONAcai berries show s specific protective effect on alcoholic hepatic injury. Its mechanism may be correlated with the inhibition of such inflammatory factors as TNF-α and IL-6.

Objective To investigate the effectiveness of the combined electrical stimulation and nursing interventions for female stress urinary incontinence.Methods The study is qusi-experimental design.48 patients with stress urinary incontinence were allocated to the intervention group and the control group with 24 patients in each group.The control group was given electrical stimulation,the intervention group was given 12-week electrical stimulation and comprehensive nursing interventions.The outcome indicators were 1-hour pad test urine loss,pelvic floor muscle (PFM) strength,the grade of subjective urinary incontinence,quality of life (I-QOL).Results Compared with the control group,no significant subjective urinary incontinence score was seen,but pelvic floor muscle (PFM ) strength and the score of the QOL evidently improved and 1-hour pad test urine loss decreased in the intervention group.Conclusions Combined electrical stimulation and nursing interventions for female stress urinary incontinence is effective treatment.

Objective To evaluate the results of NiTi shape memory alloy four-corner arthrodesis concentrator (NTMA-FCAC) for carpal collapse. Methods We reviewed retrospectively 13 patients who underwent scaphoid excision with four-corner arthrodesis using NTMA-FCAC for carpal collapse from August 2006 to June 2009. There were eight males and five females, with an average age of 38 years (range, 23-61years). The cause of carpal collapse was SNAC in 7 cases, perilunate dislocations in five and SLAC in one.The injury mechanisms included traffic accidents (5 cases), falling from a height (4 cases), crashes (3 cases)and sprain (1 case). Objective measurements included grip strength and range of the wrist. Radiographs were performed in all patients. A visual analogue scale (VAS) was used to assess wrist pain. The results were evaluated according to the Krimmer wrist scores. Results The mean follow-up time was 26.5 months (range,6-36 months). Clinical evaluation yielded the mean grip strength of (32.49±6.21) kg (80.8% of opposite side).The mean range of the wrist reached over 53% of the healthy side. Non-union and wound infection were not seen. The mean VAS scores had improved from 4.46±1.27 preoperatively to 1.31 ±0.95 postoperatively. The mean pain scores under stress had improved from 7.00±1.41 preoperatively to 2.62±1.26 postoperatively.There were remarkable differences between them. The mean Krimmer wrist score was 79. Conclusion Four-corner arthrodesis using NTMA-FCAC is an effective method for carpal collapse, preserving a majority of wrist function.
