Advanced hospitals and high-level hospitals are different from grass-root hospitals,since they not only treat difficult diseases but also have the obligation of scientific studies and teaching.Grass-root hospitals mainly focus on treating common diseases,and only conduct a small amount of teaching,thus resulting in the difference between grass-root hospitals and large-scale hospitals in the aspect of purchasing medical equipment.Because the money for grass-root hospitals may only be used as designated and some even comes from loan or collecting,we have to pinch pennies and make the best use of everything so as to recover the cost rapidly and bring the equipment into full play.

Growth arrest special 5 (GAS5) is a common long non-coding RNA (lncRNA).Recent studies find that lncRNA GAS5 is down-regulated in various tumors,such as breast cancer,cervical cancer,lung cancer,gastrointestinal cancers and urologic cancers.GAS5 is closely related to the development,metastasis and prognosis of cancers,which becomes a new hotspot in cancer research.

Recently,the relationship between psoriasis and coronary heart disease(CHD)have been casting close attention.It has been demonstrated that the prevalence of CHD in patients with psoriasis is more than one time higher than that of healthy people. Meanwhile,the prevalences of hypertension,diabetes mellitus, hyperlipoidemia and smoking in patients with psoriasis are higher than those of normal people,and some drugs for treatment of psoriasis may induce CHD.Therefore,the relationship between psoriasis and CHD is still unclear.In this paper,two cases of psoriasis complicated with CHD are reported,and the relationship between psoriasis and CHD is explored.

Objective To investigate Survivin protein and esophageal cancer with a systematic review.Methods The published studies were searched in the Cochrane Library (Issuel,2011),Pubmed and CNKI databases, and other relevant journals were also hand searched to identify all the relevant case-control trials.Then the quality of the included trials was assessed and meta-regression analysis was performed,by STATA 11.0 software.Results A total of 15 studies were recruited.As for the positive rate of Survivin expression, significant differences were tested between esophageal cancer vs.normal esophageal tissues (OR =39.98, 95 ％ CI =15.08-106.02, P ＜ 0.05).No significant difference was tested between cell differentiation G3 vs.cell differentiation G1-G2(OR =1.47,95 ％ CI =0.59-3.68,P ＞ 0.05).There were significant differences between T stagesⅢ-Ⅳ vs.T stages Ⅰ-Ⅱ (OR =2.82,95 ％ CI =1.35-5.90,P ＜ 0.05),clinic stages Ⅲ-Ⅳ vs.clinic stages Ⅰ-Ⅱ (OR =2.99, 95 ％ CI =2.03-4.41, P ＜ 0.05), lymph node metastasis vs.non-lymph node metastasis (OR =4.11,95 ％ CI =2.79-6.05,P ＜ 0.05).Moreover,Survivin expression was positively correlated with the expression of hypoxia inducible factor-1α (HIF-1α) (r =0.542,P ＜ 0.005).Conclusion Survivin expression increased malignant behaviors of esophageal cancer.There might be substantial correlations between Survivin and HIF-1α expression and esophageal cancer.

Objective To evaluate the efficacy of I-gel laryngeal mask airway (LMA) for airway management in patients undergoing radical mastectomy.Methods One hundred and twenty ASA Ⅰ or Ⅱ patients (Mallampati Ⅰ or Ⅱ),aged 25-64 yr,weighing 45-90 kg,with body mass index ＜ 30 kg/m2,scheduled for elective radical mastectomy under general anesthesia,were randomized into 2 groups (n=60 each): I-gel LMA group (group Ⅰ) and Classic LMA (group C).Anesthesia was induced with iv midazolam 0.04 mg/kg and vecuronium 0.10 mg/kg.I-gel and classic LMAs were inserted in I and C groups,respectively,after induction of anesthesia.The success rate of LMA placement at first attempt,LMA placement time,airway sealing pressure,peak airway pressure,leaks and hypoxemia,and complications (nauseas and vomiting,bucking,aspiration and blood stain on the LMAs,sore throat and hoarseness within 24 h after surgery) were recorded.Correct position of the LMAs was verified by fiberoptic bronchoscopy.Results The success rate of LMA placement were 100 ％ in both groups.The success rate of LMA placement at first attempt and fiberoptic bronchoscope scores were higher,the LMA placement time was significantly shorter,and the incidence of blood stain on the LMAs and sore throat were significantly lower in group Ⅰ than in group C (P ＜ 0.05).A transient increase in airway pressure and leaks occurred in 5 patients in group C,and the airway pressure returned to normal and no leaks developed after treatment.No transient increase in airway pressure and leaks occurred in group Ⅰ.Hypoxemia was not found in both groups.Conclusion The placement of I-gel LMA is easier than that of Classic LMA and the success rate of placement at first attempt is high,with fewer complications.I-gel LMA can be safely and effectively used for airway management in patients undergoing radical mastectomy.

Objective To understand whether Imarcaptoacetate dioctyltin(IMA) is a environmental endocrine disruptor or not. Methods The new born Wistar rats were randomly divided into six groups including positive control group, negative control group and four experimental groups. The rats in the experimental groups were given IMA at different concentrations (0.100 0, 0.010 0, 0.001 0, 0.000 1 ?g/10 g) 1/1 000 000 by hypodermic injection, the rats in the negative control group were treated with corn oil and those in the positive control group were treated with dibutyltin dilaurate(DBTD) at concentration of 0.001 ?g/10 g bw. The rats were injected one time each day for five consecutive days. After one and half months, the levels of T, LH and FSH in the blood, the weight of the testicles, ovaries and the sexual organ exponent were determined. The pathological examination on some samples was conducted. Results In both of female and male, the levels of T in IMA treated rats were significantly increased and showed an doge-effect relationship (P0.05). The exponents of the testicles were different among groups (P

Objective To determine the long-term outcomes of renal interventional therapy in patients with renal artery stenosis. Methods One hundred thirty-four consecutive patients reveived renal stenting in our hospital. The changes of BP and serum creatitine were measured 24 hours after the procedure and during the first and second year of follow-up. Results All procedures were performed successfully. The mean serum creatitine level increased [(109.8?24.6) ?mol/L vs (99.4?27.8 baseline level) ?mol/L] and the glomerular filtration rate decreased [(57.6?19.3)mL/min vs (68.5?18.9) mL/min] significantly after the procedure. However during the first and second year of follow-up, the serum creatitine level returned to the pre-procedure level. Sixty-four patients attained benefit of BP improvement at about 6 months after renal artery stenting. The mean systolic pressure 6 months after the procedure was (148.6?22.6) mm?Hg (1 mm?Hg=0.133 kPa), which was significantly lower than the baseline level. During the first and second year of follow-up, there were 56 patients (50.6%) and 50 patients (49.6%) achieved BP improvement from renal stenting respectively. Conclusion Renal stenting is efficient and has satisfactory long-term outcomes in treating renal artery stenosis.

Objective: To study the mechanism of Tuina in the treatment of skeletal muscle injury. Methods: Rabbits were heavily beaten at gastrocnemius muscle to make acute contusion model and then treated respectively by early Tuina and routine Tuina. The number of satellite cells of skeletal muscles was observed. Results: The number of the satellite cells continued to grow in both groups, and it began to increase significantly 3-5 days after Tuina treatment. Early Tuina treatment produces larger number of satellite cells than routine Tuina treatment.Conclusion: Early Tuina treatment is helpful to the marked recovery of skeletal muscles by increasing the number of satellite cell.
