ABSTRACT
Objective To evaluate the psychometric properties and the clinical feasibility of Chinese version of the Oxford Knee Score in patients with knee osteoarthritis before total knee arthroplasty.Methods One hundred and fourteen (91 females,23 males) preoperative patients with knee osteoarthritis were recruited.Internal consistency was tested using Cronbach's alpha coefficient,and dimensionality was evaluated using exploratory factor analysis.The correlations between the scale,namely,WOMAC,SF-8 and EQ-5D were used to determine construct validity.The floor and ceiling effects were also examined.Results The scale showed acceptable internal consistency (Cronbach's alpha=0.885) and demonstrated good convergent and divergent validity with the moderate to strong correlations between the scale and WOMAC (r=-0.80),the SF-8 physical component summary (r=0.65),and the EQ-5D usual activities (r=-0.41) and mobility (r=-0.35).Moreover,the strong correlation between the scale and the SF-8 mental component summary (r=0.58),as well as the moderate correlation between the scale and the EQ-5D anxiety/depression (r=-0.35) were observed.Divergent construct validity was supported by weak correlation between the scale and EQ-5D VAS (r=0.30).The exploratory factor analysis yielded three factors with eigenvalues ＞ 1,accounting for 66.02％ of the variance.All items had factor loadings above 0.4.Factor 1 closely relates to physical function,while factor 2 depicts pain associated with knee osteoarthritis.Factor 3 had only one item (item 8),reflecting the patient's sleep problems.No sign of floor or ceiling effect was found.Conclusion Chinese version of the Oxford Knee Score is proven to be a reliable,valid scale for knee osteoarthritis patients before total knee arthroplasty.
ABSTRACT
Objective To explore the preoperative localization diagnosis and surgical techniques of intractable occipital lobe epilepsy.Methods Retrospectively studied 37 patients diagnosed as occipital lobe epilepsy and underwent focal occipital resections for epilepsy.The semiology,scalp electroencephalography,MRI,fluorodeoxyglucose-positron emission tomography(FDG-PET),and intracranial EEG monitoring were used to localize the epileptogenic zones.The long-term seizure outcomes were assessed according to the Engel classification scheme.Results Visual symptoms were present in 25 patients preoperatively in this series.MRI displayed occipital lobe lesions in 15 patients,and FDG-PET revealed hypometabolism in or adjacent to epileptogenic zones.And 30 patients' epileptogenic zones and functional areas were defined by intracranial EEG monitoring.Visual field deficits were present in 35.3% of patients preoperatively,and 61% had new or aggravated visual field deficits after surgery.After a mean follow-up of 41 months,81.1% of the patients were seizure free or rarely had seizures.Conclusion The curative effect of the surgery on the medically intractable occipital lobe epilepsy is good.Intracranial EEG monitoring with electrodes extensively covering the occipital lobe and adjacent areas can be useful to demarcate the epileptogenic zones and the visural cortex,and it may prevent aggravation of the visual field deficits as much as possible.
ABSTRACT
Objective To investigate the association between the RoSCo scoring system and the postopera tive complications of laparoscopic partial nephrectomy.Methods The clinical data of 127 patients with laparoscopic partial nephrectomy in our hospital from 2010 to 2015 were retrospectively analyzed.By studying all patients' preoperative clinical data,we give all the patients the RoSCo score,then divided all the patients into the RoSCo low group (3-4),RoSCo moderate group (5-6),RoSCo high group (7-8).Respectively study the association between the RoSCo score and Clavein score,operative time,intraoperative blood loss,warm ischemia time and length of hospital stay after laparoscopic partial nephrectomy.Results The RoSCo score was associated with postoperative complications of laparoscopic partial nephrectomy (P ＜ 0.05) and was more accurate than the RENAL score alone.There were significant differences in bleeding,warm ischemia time,hospital stay and operation time between the low,middle and high groups of RoSCo (P ＜ 0.05).Conclusion The RoSCo scoring system can be used to assess the complications of laparoscopic partial nephrectomy.

ABSTRACT
Objective To investigate the different memory outcomes in temporal lobe epilepsy patients underwent different surgical approaches.Methods Two hundred forty-eight patients with temporal lobe epilepsy and hippocampal scle-rosis underwent standard anterior temporal lobectomy ( ATL, n=83 ) or selective amygdalohippocampectomy ( SAH, n=165) from 2009 to 2013.All the patients underwent clinical memory function assessment before surgery, 3 months and 2 years after surgery respectively.Results The memory quotient ( MQ) of patients who underwent brain surgery in the domi-nant hemisphere significantly decreased 3 months after surgery (74.5 ±16.2, 75.6 ±19.5) compared to presurgery MQ (82.9 ±15.8, 83.2 ±21.2) in both ATL and SAH groups (P<0.05).Although MQ was slightly recovered at 2 years af-ter surgery, MQ (75.1 ±14.1, 76.1 ±17.6) was still significantly lower compared with presurgery MQ (P<0.05).A-mong this, both the decrease extent of the MQ 3 months after surgery and 2 years after surgery were smaller in the SAH group than in the ATL group (7.6 vs.8.4;7.1 vs.7.8).The MQ of patients who underwent brain surgery in the non-dominant hemisphere (either ATL or SAH ) increased slightly 3 months after surgery (87.2 ±15.1, 88.1 ±16.9) com-pared to presurgery MQ (85.5 ±13.5, 85.3 ±19.7) although the difference was not statistically significant.The MQ of these two groups improved significantly 2 years after surgery (92.8 ±12.7, 93.7 ±17.1)(P<0.05).The improvement extent of the MQ was larger in the SAH group than in the ATL group (8.4 vs.7.3).Conclusions SAH may be better than ATL in the maintenance of memory function in patients with temporal lobe epilepsy and hippocampal sclerosis.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the factors affecting the efficacy of extracorporeal shock wave lithotripsy (ESWL) and establish a model for predicting the success rate of a single ESWL session in the treatment of single renal calculus.</p><p><b>METHODS</b>Between January 2008 and February 2010, 325 patients underwent ESWL monotherapy and were followed up for at most 3 months. The correlations between the outcome of a single ESWL session and the patients' age, gender, body mass index (BMI), disease duration, pretreatment renal colic, hematuria, urinary irritation symptoms, stone location, stone laterality, stone length and stone width were analyzed. The statistically significant factors identifies were further analyzed by multivariate logistic regression, and the predictive model was established.</p><p><b>RESULTS</b>The stone-free rate of ESWL was 76.9%. Univariate analysis found that the patients' age, stone laterality, stone location, disease duration, pretreatment hematuria, stone length and width all significantly affected the outcome of the treatment.

ABSTRACT
Objective To review the pathogenesis, pathology, diagnosis and prognosis of calci-fication or ossification renal cell carcinoma with 1 case report. Methods A 48-year-old man was re-ferred for evaluation of an incidental mass found on the upper-middle right kidney, and computed tomography showed a 7 cm tumor with extensively calcification. PET-CT found an extensively calci-fied and ossification mass without high-function in the upper-middle right kidney. Under the diagnosis of renal cell carcinoma, a transabdominal radical right nephrectomy was performed. Results During the operation, a 7.5 crux 5.0 cm well-circumscribed, encapsulated heterogeneous mass was found on the upper-middle right kidney. The patient underwent an partial nephrectomy. Frozen section diagno-sis was renal cell carcinoma with heterotopic bone formation. Then a transabdominal radical right ne-phrectomy plus regional lymph node dissection were performed. Paraffin sections showed renal cell carcinoma with heterotopic bone formation(clear cell carcinoma, pT2b No M0 ). There was neither me-tastasis nor recurrence during the 8 months follow-up. Conclusions Renal cell carcinoma with ossifi-cation is extremely rare. Renal mass with obvious substantive calcification ossification should be trea-ted as malignant mass before operation. The prognosis of renal cell carcinoma associated with ossifica-tion is relatively good.
