The liver is an important organ of the body, which has many functions, such as metabolism and detoxification. Due to the rapid change of lifestyle and the improvement of public health, the incidence rate of non-communicable diseases has increased significantly, which fundamentally changed the disease characteristics in most parts of the world. At present, the global prevalence of non-alcoholic fatty liver disease (NAFLD) is about 25%. Moreover, about 59.10% of NAFLD patients progress to non-alcoholic steatohepatitis (NASH) within 5 years, and about 41% of NASH patients progress to fibrosis. NAFLD has become one of the most important liver diseases in the world and may become the main cause of end-stage liver disease in the next few decades. In addition, NAFLD and related cirrhosis will bring huge economic burden to patients, health care system and society. Since there are currently no medications available that have been approved by Food and Drug Administration (FDA), NAFLD is still treated mainly through lifestyle changes such as exercise and diet. Oxidative stress and inflammation are the most important pathological processes in the occurrence and development of liver diseases. Nuclear factor erythroid-2-related factor 2 (Nrf2) is a key regulator of the body's antioxidant stress system, with anti-inflammatory, antioxidant and other functions. Many studies have shown that Nrf2 pathway significantly affects the progression of liver diseases. In this review, we aimed to summarize the regulatory role of the Kelch-like ECH-associating protein 1 (Keap1)-Nrf2-antioxidant response element (ARE) signaling pathway in the pathogenesis of NAFLD, and to reveal the potential of Nrf2 as a therapeutic target for NAFLD.

Objective To explore if the day surgery for cataract is safe and should be popularized. Methods From September to October in 2015, among the patients who received the ultrasonic phacoemulsification and intraocular lens implantation in the cataract department of Tianjin Medical University Eye Hospital, according to the admission time, one hundred and three patients were chosen respectively from the day ward(the experimental group)and the traditional ward(the control group)based on the purposive sampling. The average time of waiting for admission, the falls events before admission, the awareness about postoperative considerations, the postoperative complications and the infection rate between the two groups were compared. Results The average time of waiting for admission in the experimental group was much shorter than that in the control group, (6.36 ± 4.02) days vs. (21.35 ± 18.58) days. The difference was significant (Z=-8.386, P<0.01). The rate of falls before admission in the experimental group was lower than that in the control group and the difference was significant, 9.71%(10/103) vs. 20.39%(21/103),χ2=4.595, P<0.05. No infection happened in both groups. Conclusions The day surgery model doesn′t increase the risk and is as safe as the traditional surgery model. It should be extended as it also has the advantages of shorter hospital stay, less medical resource consumption and less hospitalization expenses, besides, it saves time and labor. What′s more, the mean waiting time for hospitalization for day surgery is shorter. It means the patients can receive the operation as soon as possible, which ensures the patients′safety, and reduce the unsafe factor in their life, bring the benefit to the society.

OBJECTIVE: To introduce material science characteristics and clinical application of bone plate. METHODS: The first author retrieved PubMed Database (http://www.ncbi.nlm.nih.gov/), China National Knowledge Infrastructure (http://www.cnki.net/) and Wanfang Database (http://www.wanfangdata.com.cn) for articles addressing material science characteristics and clinical application of bone plate published from 2000 to 2009. The key words included "bone plate, material science characteristics, biocompatibility, clinical application". Testing articles with reliable argument and evidence as well as close topic were included, and simultaneously, non-original articles were excluded. Ultimately, 25 articles were included. We arranged and analyzed material science characteristics, clinical application, advantages and disadvantages of bone plate. RESULTS: From the material science characteristics, the elastic modulus of bone plate should be close to skeleton so as to reduce stress occlusion effects. In clinical application, we should pad attention to the bonding of biological fixation and mechanical fixation to improve plate structure, resulting in decrease in contacting area of plate and skeleton to diminish or prevent osteoporosis in local regions. CONCLUSION: Presently, bone plate materials mainly contain stainless steel, cobalt alloy and titanium alloy in clinic with their advantages and disadvantages. Among them, medical titanium alloy is an ideal in vivo implant. In clinical application, less invasive stabilization plate provides a powerful technique security for early recovery of motor function following fracture, and shows a spacious application prospect.

ObjectiveTo evaluate th effect and safety of tolterodine on detrusor hyperreflexia of patients with spinal cord injury.Methods20 cases of spinal cord injury patients with detrusor hyperreflexia were treated with tolterodine (2mg, twice daily), and the data of urodynamics and voiding diary before and after treatment were evaluated.ResultsAfter 12 weeks of treatment, it showed a significant increase from baseline in mean voiding volume (P<0.01), functional bladder volume (P<0.05) and interval of voiding (P<0.01). The bladder volume at first contraction significantly increased from (62.62±36.37)ml to (126.75±34.64)ml (P<0.01), the maximal pressure of detrusor contraction significantly decreased from (74.81±28.60) cm H2O to (61.90±16.22) cm H2O (P<0.05), the maximal amplitude of wave significantly decreased from (47.24±30.42) cm H2O to (39.36±25.28) cm H2O.ConclusionTolterodine is effective and safety to detrusor hyperreflexia of patients with spinal cord injury, and has a better therapeutic compliance and less adverse reactions.

Clinical features and thyroid-stimulating antibody(TSAb)in 32 newly diagnosed patients with Graves' ophthalmopathy(GO)were compared with those in 27 Graves' disease(GD)patients without GO(as control group).All of the patients with GO received intravenous glucocorticoids.The level of serum TSAb in patients with GO was significantly higher than that in patients without GO.TSAb was also associated with the prognosis.It suggests that TSAb seems to be the most active component among the TSH receptor antibodies related to ophthalmopathy and may act as a predictive parameter.

Background and purpose:With the recognition of prognostic factors and application of surgical- pathological staging,the treatment strategy of endometrial cancer has greatly changed.In this study,we investigated the treatment strategy,survival rate and prognostic factors of endometrial cancer.Methods:Five hundred and fifty-nine patients of endometrial cancer underwent primary surgical treatment from January 1996 to December 2006 in Cancer Hospital,Fudan University.The clinicopathologic parameters and prognosis were analyzed retrospectively.Results: Patients were followed up with the median period 36 months,25 cases experienced local relapse,24 cases were found to have distant metastases.The 3-year overall survival(OS)was 88.7%,3-year and 5-year disease free survival(DFS) was 82.7% and 80.9%.The 3-year overall survival(OS)were 95.5% in stageⅠ,95.3% in stageⅡ,75.9% in stageⅢand 32.4% in stageⅣrespectively(P

OBJECTIVETo investigate the effect of 6-gingerol, the main active component of ginger, on hair shaft elongation in vitro and hair growth in vivo.

METHODSFirstly, Hair follicles were co-cultured with 3 different concentration of 6-gingerol for 5 days and hair elongation in three groups was measured. Secondly, The proliferative effect of 6-gingerol on DPCs was measured using MTT assay. Thirdly, the expression of Bcl-2 and Bax in DPCs were measured using Western blotting. In vivo study, the influence of 6-gingerol on hair growth in C57BL/6 rats was measured through topical application of 6-gingerol on the dorsal skin of each animal.

RESULTSThe length of hair shaft in 20 microg/ml 6-Gingerol group (0.50 +/- 0.08 mm) is less than 0 microg/ml (0.66 +/- 0.19) mm and 10 microg/ml (0.64 +/- 0.03) mm 6-Gingerol group (P < 0.05). In cell culture, compared to 0 microg/ml and 5 microg/ml 6-Gingerol, 10 microg/ml 6-Gingerol can significantly inhibited the proliferation of DPCs (P < 0.05). Along with the growth inhibition of DPCs by 6-gingerol, the Bax/Bcl-2 ratio increased obviously. In vivo study, the hair length and density decreased a lot after using 1 mg/ml 6-gingerol.

CONCLUSIONS6-Gingerol can suppress human hair shaft elongation because it has pro-apoptotic effects on DPCs via increasing Bax/Bcl-2 ratio. It might inhibit hair growth by prolonging the telogen stage in vivo.
