Objective To investigate the morbidity and influencing infactors of plantar fasciitis in nurses. Methods The clinical nursing staff of 829 people were included in this series. 71 people of them conform to the standard of plantar fasciitis. According to the proportion of 1:1, 71 nurses without plantar fasciitis were included in the control group. The thickness and hardness index of the plantar fascia were detected by ultrasound elasticity. The survey contents including age, the average working hours every day (h), the average standing time in working day (h), body weight, body mass index (BMI), number of night shift, average walking time every day (min) and the average weekly running time (hour) were conducted. The single factor and multi-factor regression method were used to analyze the influence factors of the onset of plantar fascia. Results 71 cases of 829 nurses were with plantar fasciitis, and the incidence was 8.56%. The thickness in observation group was (3.86±0.53) mm, which was significantly smaller than (2.67±0.39) mm of the control group (P<0.05). Hardness index was 2.01±0.23, lower than 3.83±0.70 in control group (t=14.09, P<0.05). Single factor analysis results showed that the average standing time in working day, weight, BMI, average walking time every day, the average weekly running time were different between the two groups (P<0.05). The regression equation: the plantar fascia hardness index =-25.34 + 4.78 × the average standing time in working day + 3.45 × weight + 1.22 × BMI. The equation of the ability to explain the plantar fascia hardness index reached 72.2%, and had a good effectiveness. Conclusions Body weight and BMI, prolonged standing work may induce the nurse plantar fasciitis, and they are independent risk factors.

Objective: To explore the effect of emergency operation of ruptured anterior circulation aneurysms. Methods: Fifty-one patients with ruptured anterior circulation aneurysms, who present with spontaneous subarachnoid hemorrhage (SAH), were classified according to Hunt-Hess grade. All patients had CT scanning and three-dimensional spiral CT angiography (CTA) first, and then they had global digital subtraction angiography. The aneurysms were treated with emergent surgery and evacuation of intracranio-hematoma. Results: Fifty-five aneurysms were detected by CTA, among them 26 were internal carotid-posterior communicating artery aneurysms, 20 were anterior communicating artery aneurysms, 5 were middle cerebral artery aneurysms, and 4 were internal carotid-anterior choroidal artery aneurysms. Fifty-one aneurysms were clipped, and 4 were wrapped. The follow up period was 4 to 36 months, 42 patients had good outcome, 7 had moderate disability, I lived in a vegetative state, and I died. Conclusion: The effect of emergency surgery is good for patients with ruptured anterior circulation aneurysms (Hunt-Hess grade I to IV).

Objective To evaluate the murine model of dry eye induced by hyperosmolar saline. Methods Sixty female BALB/c mice at the age of 6 -8 weeks were randomly divided into blank group,control group and experimental group,20 in each group. Mice in control and experimental groups were treated with 308 mOsmol/L and 500 mOsmol/L sodium chloride solution,respectively,5 times a day. Mice in blank group were not treated with sodium chloride solution. Schirmer test,fluorescein staining,corneal scoring,rose bengal staining,tear ferns experiment,corneal epithelial HE staining and thickness measurement,conjunctival epithelial PAS staining and Goblet cell counting were conducted on days 0,7,14,28,and 42,respectively.

BACKGROUND: Renal tubulointerstitial fibrosis is mainly featured as the accumulation of extracellular matrix (ECM) in renal interstitium. The tubular epithelial-myofibroblast transdifferentiation (TEMT) is important to the pathogenesy of renal tubulointerstitial fibrosis. OBJECTIVE: To examine the effects of sodium ferulate (SF) on TEMT, and ECM main components such as collagen Ⅰ, collagen Ⅲ and fibronectin, in rat renal tubular epithelial cellsinduced by transforming growth factor-beta 1 (TGF- β1)- DESIGN: Randomized and controlled experimental study based on cells. SETTING: Department of Kidney in West China Hospital of Sichuan University. MATERIALS: Rat renal tubular epithelial cells (NRK-52E) originated from American Type Culture Collection (ATCC), were offered by the laboratory of Department of Nephrology in Australian Monash Medical Center. Cell strain used in this study was cultured at the 36th passage. SF white crystal with water solubility and more than 98.0% purify, was from Chengdu Hengda Pharmaceutical Co., Ltd. Different concentrations of SF (125,250, 500μreel/L) were designed in this study. Rabbit anti-rat α-smooth muscle actin (α -SMA) was produced by Wuhan Boster Company. Enzyme-linked immunosorbent assay (ELISA) kit was the produced of Shanghai Senxiong Science and Technology Co.,Ltd. Human recombinant TGF- β1 was produced by R&D Company. DNA Engine OpticonTM real-time fluorescence quantitative polymerase chain reaction apparatus was the product of MJ Research Company. METHODS: Rat renal tubular epithelial cells (NRK-52E) cultured in vitro were divided into five groups. Control group was added with serum-contained DMEM; TGF-β1-induced group was added with TGF-β1 at final concentration of 5 ng/L; SF at different concentrations groups were added with 125, 250, 500 μ mol/L SF and TGF- β1 at final concentration of 5 ng/L,respectively. MAIN OUTCOME MEASURES: The contrast phase microscope, real-time fluorescence quantitative polymerase chain reaction and ELISA method were used to detect TEMT of NRK52E cells induced by TGF-β1 and levels of collagen Ⅰ, collagen Ⅲ and fibronectin in the supernatant. RESULTS: Morphology of NRK52E cells: Compared with control group, TGF-β1 could induce the transdifferentiation of NRK52E cells, showing fibroblast-like in morphology after 3 days, which were previously the typical road stone-like epithelial cells. In three different concentration SF groups, the morphologic transformation stimulated by TGF-β1 could be partly ameliorated in a dose-dependent manner. Expression of α-SMA mRNA: Compared with control group, 5 ng/L TGF- β1 enhanced expression of α-SMA at 6 hours, and reached a peak at 72 hours; SF depressed the expression in a dose-dependent manner at 72 hours (P < 0.05). Changes of ECM: After induced by 5 ng/L TGF- β1 for 72 hours, the levels of collagen Ⅰ, collagen Ⅲ and fibronectin in the supernatant increased significantly (P < 0.05), whereas SF decreased these levels in a dose-dependent manner (P < 0.05). CONCLUSION: TGF- β1 induces the TEMT, and promotes the secretion of collagen Ⅰ, collagen Ⅲ and fibronectin. SF can inhibit TGF- β1-induced TEMT In a dose-dependent manner.

Objective To explore the effect of Ferroprotin 1 expression on tumorigenesis,invasiveness and survival of breast cancer.Methods In this study,100 breast cancer patients were enrolled.IHC SP was used to detect the expression of Ferroprotinl in paraffin-embedded tissues.The `association of Ferroprotin 1 expression and clinico-pathological parameters was evaluated by chi-square test.Survival analysis was calculated by Kaplan-Meier model and Log-rank test.Results The expression of Ferroprotin 1 was significantly higher in para-cancerous normal tissues (37/100,37％ ) than that in breast cancer tissues (24/100,24％ ;P =0.046 ).In these with positive axillary LN,there were more with low expression level of Ferroprotin 1 ( 36/40,90％ ) than those with high expression level ( 4/40,10％ ),P =0.007.More patients with low Ferroprotin1 were at advanced stage than those with high ferroprotin1 [Ⅲ 44/57 (77.2％) ;Ⅳ 17/18 ( 94.4％ )]( P =0.05 ).No significant association was found between ferroprotin1 and tumor grade,histology type,ER/PR,HER2,tumor size (P＞0.05).Ferroprotin1 has no significant effect on breast cancer survival ( P =0.591 ) by Kaplan-Meier curve and Log-rank test.Conclusions Low Ferroprotin 1 may lead to the tumorigenesis of breast cancer.Downregulated Ferroprotin1 promotes the LN involvement of breast cancer and accompanies with more advanced disease.However Ferroprotinl might not play an important role in the survival of breast cancer.

OBJECTIVETo evaluate the clinical results of the medial patellofemoral ligament (MPFL) reconstruction combined with the lateral retinacular release for the treatment of recurrent patellar dislocation.

METHODSFrom March 2011 to June 2013, 15 patients with recurrent patellar dislocation underwent arthroscopic MPFL reconstruction combined with the lateral retinacular release. The graft was autogenous semitendinosus and semimembranosus tendon. There were 5 males and 10 females with an average age of 19.4 years old (ranged,14 to 32 years old). The patients suffered recurrent patellar dislocation at least twice preoperatively. Preoperative conventional X-ray, CT, and MR examination were used to analyze the causes of the patellofemoral joint and MPFL injury. Preoperative Lysholm score was 69.85 ± 11.52. During operation, the arthroscopic examination was performed to evaluate the patellofemoral alignment and patellar tracking.

RESULTSAll the patients were followed up for an average of 27.6 months (ranged,12 to 36 months) with no recurrent dislocation and sub-dislocation. All the patients showed negative apprehension test at straight and 30 ° flexions of knee. The range of motion of knee returned to normal level at 12 months after operation. There were no patients with subjective discomfort of knee. Postoperative Lysholm score was improved to 92.60 ± 5.75.

CONCLUSIONThe technique of arthroscopic MPFL reconstruction combined with the lateral retinacular release is an effective surgical procedure for the treatment of recurrent patellar dislocation, which can relieve the symptom of knee and improve the patella stability and knee function.
