OBJECTIVETo evaluation the clinical effect of combination of traditional Chinese medicine and western medicine on Bell's palsy.

METHODS83 patients with Bell's palsy were randomly divided into two groups (trail group 54 cases and control group 29 cases). Patients in two groups were treated with medicine, acupuncture, physiotherapy, while patients in the trail group were treated with massage and functional exercise as the same time. The results of both groups were evaluated according to Portmann's Simple Scale.

RESULTSThe score before treatment of trail group was 2.907 +/- 1.794, while control group was 2.931 +/- 2.034. And the score after treatment of trail group was 18.593 +/- 1.743, while control group was 9.862 +/- 3.091. Score of the function of facial muscles obtained from trail group was distinctly higher than that was from the control group (P < 0.01), as well as the improvement index (P < 0.01, trail group: 0.844 +/- 0.095, control group: 0.712 +/- 0.129).

CONCLUSIONThere is significant curative effect and suitability in the treatment of Bell's palsy with combination of traditional Chinese medicine and western medicine. The improvement of facial muscles' motive function pre- and post-treatment and quantitative evaluation of curative effect can be objectively obtained by evaluation of facial muscles' function.

Objective To determine non-thermal biological effect of low frequency pulsed electromagnetic field (LFPEF)on the stomach blood circulation and ultra microstructure of rat stress ulcer. Methods Thirty-six Sprague-Dawley rats were assigned to three equal groups:control,ulcer without interference group(UW)and ulcer exposure groups(UE).The rats stress ulcer models were constructed with the combination method of soak and bind in the low-pressure and hypoxia circumstance. Based on the singlechip,a LFPEF generator with adjustable frequency, amplitude and duty ratio was developed. Then the stomachs of the rats were exposed to the LFPEF generator 3 hours per day.On days 1,3,5 and 7,the blood circulation of the stomach was analyzed by the content of the serum NO and contrast ultrasonography.In addition,the ulcer tissue was taken out for section-staining. Finally, the pathological change of the stomach ultra microstructure was observed under a light microscope. Results On different days, the contents of the serum NO and microbubble concentration of UE group were significantly higher than those of the UW group(P<0.05). The pathological observation showed that the restoration of the gastric tissue in UE group was faster than that in the UW group(P<0.05).Conclusion LFPEF with certain proper parameter could improve the gastric tissue blood circulation and accelerate the stress ulcer restoration.

BACKGROUNDAssessing the radiographic features of knee osteoarthritis (OA), especially joint space narrowing, is important for evaluating disease progression. The purpose of this study was to quantitatively analyze joint space narrowing by measuring 2 new variables: the average joint space width (aJSW) and the articulate angle (AA) on X-ray films, and to evaluate the relationship between the 2 variables, knee function and OA symptoms.

METHODSUsing the web-based radiology viewer (Cedara I-Reach™ 4.1.1), we measured the 2 variables in 50 knees of 41 patients with knee OA participating in the Shanghai OA Study. We also evaluated the Kellgren-Lawrence (K-L) grade, the Western Ontario and McMaster Universities OA Index (WOMAC), and additional questionnaire in OA knees. The study was approved by the ethics committee of Shanghai Ninth People's Hospital (No. 2009 - 28).

RESULTSThe aJSW correlated with the K-L grade (r = -0.57, P < 0.001), kneeling (r = -0.29, P = 0.04), sitting cross-legged on the floor (r = -0.31, P = 0.03), WOMAC pain (r = -0.31, P = 0.03), WOMAC disability (r = -0.35, P = 0.01), pain while squatting (r = -0.37, P = 0.01), and defecating in a squatting position (r = -0.39, P = 0.01). The AA correlated with defecating in a squatting position (r = 0.29, P = 0.05), WOMAC disability (r = 0.30, P = 0.04) and K-L grade (r = 0.44, P = 0.003). The K-L grade also correlated with pain while squatting (r = -0.40, P = 0.005) and defecating in a squatting position (r = -0.34, P = 0.02), WOMAC pain (r = 0.30, P = 0.04), and WOMAC disability (r = 0.30, P = 0.04).

CONCLUSIONSThe aJSW closely correlated with knee OA symptoms and function scores, and was more sensitive to knee OA related disabilities than K-L grade and the AA. The aJSW could be used as a new variable for knee OA evaluation.

BACKGROUNDDetermination of the proper orientation of the knee articular surface is required both for correction of knee malalignment by osteotomy and for correct component alignment in knee arthroplasty. We sought to determine whether the patients' sex and lower extremity alignment (hip-knee-ankle angle) affects proper knee realignment in osteotomy or component alignment in total knee arthroplasty.

METHODSWe examined 199 healthy adult knees with malalignment of < 5° to determine the mechanical medial distal femoral angle, mechanical medial proximal tibial angle, surgical transepicondylar axis angle, and discrepancies between bone-cut orientations of osteotomy or total knee arthroplasty and the joint line of the distal femoral condyles, posterior femoral condyles and proximal tibial plateaus, using a three-dimensional computed tomography model.

RESULTSThe mean mechanical medial distal femoral angle and mean mechanical medial proximal tibial angle were (94.4 ± 1.9)° and (87.6 ± 1.8)° respectively for women and (93.8 ± 2.0)° and (87.1 ± 1.4)° respectively for men. The surgical transepicondylar axis angle was (2.9 ± 1.6)° for women and (3.2 ± 1.7)° for men. Independent of sex, the hip-knee-ankle angle was closely related to the mechanical medial distal femoral angle and mechanical medial proximal tibial angle, but not to the surgical transepicondylar axis angle. A slightly more valgus alignment of the knee and a more valgus angulation of the distal femoral joint line were found in women, whereas a more varus angulation of the proximal tibial joint line was found in men. Sex had the greatest effect on knee joint line orientation when the lower extremity was valgus in alignment.

CONCLUSIONSA more valgus femoral joint line can be expected in women and in persons with valgus lower extremity alignment; a more varus tibial joint line can be found in men and in persons with varus lower extremity alignment.

BACKGROUNDThe recurrence of pterygium after surgery is high. A variety of adjunctive treatment approaches have been developed to improve the clinical efficacy and many related articles have been published. This study aimed to determine the risk for postoperative pterygium recurrence comparing autologous conjunctival transplantation (ACT) versus mitomycin C (MMC).

METHODSRelevant literature published until December 2010 in Medline, Embase, Cochrane, Cochrane library, Science Citation Index, and Google Scholar were searched. Qualified random clinical trial (RCT) studies on the comparison of recurrence rate of pterygium after ACT and MMC treatment were included in this study.

RESULTSEight RCTs with 663 eyes entered the final analysis. The recurrent rate of pterygium was 8.7% (30/343) for ACT and 18.75% (60/320) for MMC. Using fixed-effect meta analysis, we found that the recurrence was significantly lower after ACT than MMC treatment (odds ratio (OR) = 0.40, 95% confidence index (CI), 0.25 - 0.63, P < 0.0001). In sensitivity analyses, we employed random-effects model and excluded studies of low quality or studies in which MMC was administrated after the operation. All the sensitivity analyses confirmed that ACT led to lower recurrence rates than MMC. Sub-group analysis revealed that the recurrence rate was 20.2% (20/99) and 27.65% (26/94) for conjunctival autograft (CA) and MMC respectively, and no significant difference in the recurrence rate was detected (OR = 0.65, 95%CI 0.33 - 1.28, P = 0.22). However, we found that conjunctival limbal autograft (CLA) had lower recurrence rate than MMC (OR = 0.26, 95%CI 0.14 - 0.48, P = 0.0001).

CONCLUSIONCLA has better therapy efficacy against the recurrence of pterygium than MMC.

OBJECTIVE: To explore the obesity distribution in old people and the relation between senile obesity and health. METHODS: First, a questionnaire was designed which included chronic disease history, body mass index (BMI), physiological value, biochemistry index, anti-oxidation index, diagnosis of diseases, etc. Second, the measure and detection methods were unified; and the last, the investigation was made along with daily clinical work by clinicians. RESULTS: We received 391 questionnaires. The overweight rate was 36.1% and the obesity rate was 7.9% . Total anti-oxidation activity in serum (TAS) and superoxide dismutase (SOD) decreased with body mass index (BMI), and the value in the obesity group was the lowest; Malonaldehyde (MDA) of overweight obesity was the largest. The mean blood pressure, blood fat, and blood glucose as well as the prevalence of cardiovascular disease, hyperlipemia, and glycuresis increased with BMI; and the value in the obesity group was the largest. CONCLUSION The prevalence of the senile obesity was below the average and the senile obesity complications were various and serious, and perhaps related to imbalance of free radical's production and cleanup, so the senile obesity seriously harmed old people's health.

BACKGROUNDSynovium-derived stem cells (SDSCs) with higher chondrogenic potential are attracting considerable attention as a cell source for cartilage regeneration. We investigated the effect of bone morphogenetic protein 2 (BMP-2) on transforming growth factor beta3 (TGF-β3)-induced chondrogenesis of SDSCs isolated from human osteoarthritic synovium in a pellet culture system.

METHODSThe clonogenicity, stem cell marker expression and multi-differentiation potential of isolated SDSCs were determined by colony forming unit assay, flow cytometry and specific staining including alizarin red S, Oil red O and alcian blue staining, respectively. SDSCs pellet was cultured in chondrogenic medium with or without TGF-β3 or/and BMP-2. At day 21, the diameter and the weight of the pellets were measured. Chondrogenic differentiation of SDSCs was evaluated by Safranin O staining, immunohistochemical staining of collagen type II, sulfated glycosaminoglycan (sGAG) synthesis and mRNA expression of collagen type II, aggrecan, SOX9, link-protein, collagen type X and BMP receptor II.

RESULTSCells isolated under the optimized culturing density (10(4)/60 cm(2)) showed clonogenicity and multi-differentiation potential. These cells were positive (> 99%) for CD44, CD90, CD105 and negative (< 10%) for CD34 and CD71. SDSCs differentiated to a chondrocytic phenotype in chondrogenic medium containing TGF-β3 with or without BMP-2. Safranin O staining of the extracellular matrix was positive and the expression of collagen type II was detected. Cell pellets treated with TGF-β3 and BMP-2 were larger in diameter and weight, produced more sGAGs, and expressed higher levels of collagen type II and other chondrogenic markers, except COL10A1, than medium with TGF-β3 alone.

CONCLUSIONSSDSCs could be isolated from human osteoarthritic synovium. Supplementation with BMP-2 significantly promoted the in vitro TGF-β3-induced chondrogenic differentiation of SDSCs.

OBJECTIVETo investigate the effect of docosahexaenoic acid (DHA) on invasiveness of aflatoxin B1 (AFB1)-induced hepatocellular carcinoma cells in vitro.

METHODSHepG2.2.15 cells were exposed to different concentrations of AFB1 and DHA plus AFB1. The cell migration and invasion were assessed using wound-healing and Transwell assay, and flow cytometry was used to analyze the cell cycle changes. The ultrastructural changes of the cells were observed by transmission electron microscopy.

RESULTSCompared with the control group, the cells exposed to2 µmol/L AFB1 showed obviously enhanced migration and invasion with decreased cell ratio in G1/G1 phase and increased cell ratio in G2/M phase but no changes in S phase cells; transmission electron microscopy revealed the presence of multiple nucleoli and significantly increased mitochondria and Golgi apparatus in the exposed cells. Compared with AFB1-exposed cells, the cells treated with DHA and AFB1 showed decreased migration and invasion abilities, and the G1/G1 phase cells increased and G2/M phase cells decreased significantly; ultrastructurally, the cells contained single nucleoli with decreased mitochondria and vacuolization occurred in the cytoplasm.

CONCLUSIONDHA can significantly inhibit AFB1-induced enhancement of cell migration and invasion in hepatocellular carcinoma cells in vitro.
