MicroRNAs(miRNAs) are a newly discovered class of small noncoding RNAs that rcgulate gene expression by translational repression or mRNA degradation.It has become evident that miRNAs are involved in many important biological processes,including tissue differentiation and development,showing a tissue specificity and development-stage specificity.In the other hand,miRNAs play critical roles in neovascularization and a variety of pathophysiological processes,such as pathological angiogenesis,oxidative stress response,immune response and inflammation.Currently,miRNAs of the retina,lens and cornea have been established,and they would be potential therapeutic targets in the eye diseases.Here,the distribution of miRNAs in the eye and their role in ocular diseases were summarized.

Objective To observe the therapeutic effect of Chinese herbal and western medicines(CHM & WM)combined with acupoint pulse-laser stimulation(APLS)for calculus of upper urinary tract.Methods Sixty cases of calculus of upper urinary tract were allocated to the treatment group(Group A,n=36)and the control group (Group B,n=24).Group A was treated with CHM & WM combined with APLS and Group B with CHM alone.Results The therapeutic effect rate was 94.4% and 75.0% in Group A and Group B respectively (P

Rectal cancer is one of the common malignant tumors in China,and the incidence rate is rising year by year.Comprehensive treatment based on surgical operation is the major treatment of low rectal cancer.The treatment concept requires not only radical resection of tumor,but also preservation of the anal and urogenital function,to improve the quality of patients' life.By improving the accuracy of preoperative staging of rectal cancer,neoadjuvant therapy,and following the principle of total mesorectal excision,patients can benefit in terms of increased resection rate,decreased operation complication incidence,increased sphincter preservation,decreased local recurrence and increased overall survival rate.With the development of medical technology,minimally invasive surgery of low rectal cancer has been developed rapidly.In this paper,new progress in the surgical treatment of low rectal cancer will be reviewed.

Alzheimer's disease(AD) is one of the most common causes of mental deterioration in elderly individuals, accounting for around 45~60% of the overall cases of dementia over 65 years of age. Although there is presently no "cure" for AD, a large number of potential therapeutic interventions have emerged to correct cholinergic dysfunctions. Currently, cholinergic therapy, particularly cholinesterase inhibition, represents the most realistic approach to the symptomatic treatment of AD. Modest efficacy for mild to moderate AD has been shown in well-designed clinical trials for tacrine, donepezil, rivastigmine, and galantimine. Among other treatment options, estrogen replacement therapy in postmenopausal women is under active investigation, but recent studies showed somewhat disappointing results. Epidemiological and clinical data suggest that nonsteroidal anti-inflammatory drugs are beneficial in the treatment and prevention of AD. But prednisone and COX-2 inhibitor, celecoxib showed no clinical benefit in recent studies. Alpha-tocopherol and gingko biloba showed some beneficial effect in delaying the progression of AD and enhancing cognitive functions. Immunization with beta amyloid peptide was considered to be the only method to prevent and halt disease progression in patients with AD. Recently, phase II clinical trial using synthetic beta amyloid peptide (AN-1792) was discontinued because some patients showed neuro-inflammation which may be caused by autoimmune responses.

The pathological changes of hallux valgus are diversity, including adduct of metatarsus primus, increasing of the intermetatarsal angle between the first and second metatarsal bones, increasing of hallux valgus angle, dislocation of sesamoides, lost of soft tissue balancing. X-ray is the most important method to measure the pathological changes of hallux valgus. The multiformity of hallus valgus pathological changes makes manner of repairing variety. The main methods include operation on soft tissue, osseous surgery, fusion of joint and figuration of joints. The selection of the surgical methods should be individualization according to the idiographic pathological changes of hallux valgus patients.

Objective To construct a computerized medical case archive system, which can realize the electronic storage of medical case. Methods Virtual print was used in archive computerized medical cases and electronic signature was used to ensure the legality of the archives. Results The system realized the patient-centered medical information integration and raised the level of medical information storage and management significantly. Conclusion The favorable foundation was established fully in the medical cases archiving system, but the system can be improved in future.

Objective To investigate the effect of Naloxone in the pre-hospital care of AOPP.Methods 54 patients with the pre-hospital care of AOPP were divideded into two groups.The treatment group was treated with Naloxone,Atropine and Pyridine aldoxime methyliodide,the control group treated with Atropine and Pyridine aldoxime methyliodide,and the results were analyzed using t-test and x2 test.The efficacy of the two groupswas compareded.Results In the treatment group,the mumber of drug delivery and the dosage of Atropine were less.The recovery time of the actirity of Cholinesterase and the patients coma were shorter.Complications and mortality was significantly lower,but the cure rate was significantly higher than that of the control group.Conclusion Naloxone is effective and safe in the treatment the pre-hospital care of AOPP.It is worthy of clinical promotion.

Objective To study the early diagnostic value of procalcitonin(PCT),high-sensitivity C-reactive pro-tein(hs-CRP)and interleukin-6(IL-6)in catheter-related bloodstream infection (CRBSI)in patients in intensive care unit(ICU).Methods 78 ICU patients with suspected CRBSI between April 2013 and April 2015 were selected, blood specimens of patients on the first day of admission and being suspected CRBSI were taken,blood and venous catheter tips were performed culture,patients were divided into CRBSI group and non-CRBSI group according to culture results of blood and venous catheter tips,diagnostic values of PCT,hs-CRP,and IL-6 were compared. Results 28 patients were diagnosed CRBSI.On the day of being suspected with CRBSI,levels of PCT,hs-CRP, IL-6,and white blood cell (WBC)in CRBSI group were significantly higher than non-CRBSI group respectively ([3.35±1 .52]μg/L vs [1 .22±0.44]μg/L;[32.90 ±11 .10]mg/L vs [23.50 ±6.00]mg/L;[423.20 ±171 .70] ng/L vs [257.90±81 .40]ng/L;[12.70±2.70]×109/L vs [11 .20±1 .90]×109/L],P <0.05 ).The receiver op-erating characteristic curve(ROC)analysis showed that area under the curve (AUC)and 95% CI of PCT,hs-CRP, IL-6,and WBC were 0.92(0.85,0.99),0.75(0.62,0.88),0.80(0.67,0.92),and 0.64(0.50,0.72)respectively;sensitivity were 0.82,0.64,0.71 ,and 0.46 respectively;specificity were 0.92,0.94,0.92,and 0.88 respectively. Conclusion PCT and IL-6 have high effectiveness for early diagnosis of CRBSI in ICU patients,and have certain predictive value for early diagnosis of CRBSI.

Objective To assess the application and effects of meticulous capsular dissection technique in the prevention of recurrent laryngeal nerve and parathyroid injuries in thyroid operations . Methods A retrospective analysis of clinical data of 195 cases which received meticulous capsular dissection technique in thyroid operations from June 2007 to June 2012 was carried out .All the cases were supermicro-dissected in the loose clearance between real and false thyroid capsules , leaving the blood vessel dissected close to the real thyroid capsule . Results The operation was successfully performed in all the 195 patients, with recurrent laryngeal nerve clearly exposed in the operation in 9 patients.There were 4 cases of transient recurrent laryngeal nerve paralysis (2.1%) and 1 case of permanent paralysis (0.5%).No permanent recurrent laryngeal nerve and superior laryngeal nerve injuries and permanent hypoparathyroidism happened in the remaining cases . Conclusion The use of meticulous capsular dissection technique not only can effectively avoid the superior laryngeal nerve and recurrent laryngeal nerve injuries , but also can preserve in situ parathyroid glands and their nutrient vessels .
