Clinical practice guidelines play an important role in practitioner and patient decisions regarding appropriate clinical health care and in health policy formation. In the guideline development process, inappropriate methodologies and development strategies significantly influence the quality of guidelines; therefore, research and evaluation of guidelines have great significance. The original Appraisal of Guidelines for Research and Evaluation (AGREE) instrument was published in 2003 by a group of international guideline developers and researchers. AGREE has important significance for the quality guarantee and successful implementation of guidelines, and has extensively achieved endorsement since 2003. In 2009, The AGREE Collaboration has developed the AGREE II by refining the original AGREE instrument. At present, the AGREE II has already replaced the original AGREE instrument; however, related introduction regarding AGREE II has not been found in China. The authors of this article briefly introduce the AGREE II, and believe that it will add value to research and evaluation of the guidelines as a whole.

MEDLINE,Ovid,CNKI,and Vip Database were retrieved for articles of diuretics induced hyponatremia.6 retrospective studies,2 prospective studies,and 31 case reports were included.Pearson correlation coefficient of the cumulative dose and serum sodium level was-0.121 (P =0.757).It is suggested that serum sodium level should be closely monitored while administrating diuretics,especially in patients with high-risk of hyponatremia.

Objective To study the expression of vascular endothelial growth factor C (VEGF-C), which is known to be capable of inducing cell proliferation of lymphatic endothelium and development of lymphatic vessels, and to study its correlation with cervical lymph node metastasis in human laryngeal carcinomas. Methods The expression of VEGF-C protein in the cancer, its adjacent tissue, and normal tissue obtained from resected specimens of 46 cases of laryngeal cancer was assessed with an immunohistochemical staining assay followed by light microscopic examination, and its relationship with cervical lymph node metastasis was analyzed. Results Immunohistochemical staining of VEGF-C was different obviously in different localities of the resected. The expression of VEGF-C protein was observed in all the central portion, peripheral tissue, and normal tissue of the postoperative specimens. The positive rate of intratumoral VEGF-C was significantly higher than that of adjacent and normal tissue. It was also noted that the positive rate of intratumoral VEGF-C was well correlated with pathological grades, T stages and stages of lymph node metastasis. Conclusions The results suggested that VEGF-C may be a factor of lymphatic metastasis of laryngeal cancer, and it is possible to be used as a predictor of lmphatic metastasis of laryngeal cancer.

Objective To explore influence of Naoxintong capsule combined with edaravone on clinical efficacy and vascular endothelial function of patients with type-2 diabetes complicated with cerebral infarction.Methods 80 cases of patients with type-2 diabetes complicated with cerebral infarction treated in Shengsi People's Hospital in Zhejiang from January 2014 to January 2016 were selected as the objects, and were divided into control group and study group randomly, forty-one cases in each group.The control group were given edaravone treatment, and the study group were added Naoxintong capsule on the basis of the control group, treatment for two weeks in the two groups.Clinical therapeutic effect of the two groups and changes of TCM syndrome score before and after treatment were compared, and scores of nerve function defect and daily life ability were evaluated, and changes of blood glucose and glycosylated hemoglobin levels were detected, and endothelin ( ET-1 ) , nitric oxide ( NO ) , thromboxane B2 ( TXB2 ) and 6-keto prostaglandin F1(6-keto-PGF1) were tested before and after treatment in the two groups.Adverse reactions were observed in the two groups in treatment.

Objective To investigate the efficiency of the modified posterolateral curved incision with double intermuscular approach in the treatment of posterolateral tibial plateau fractures.Methods From August 2009 to March 2013,15 men and 17 women aged 28 to 77 (mean,46.25) years with posterolateral spitting or collapse tibial plateau fractures were treated to undergo a modified posterolateral approach.All types of fractures were closed,without nerve or artery injury.The duration from injury to fixation was 3-18 (mean,7.13) days.The modified posterolateral approach was preformed to expose tibial anterolateral condyle and posterolateral condyle through intermuscular space of anterior tibial muscle,popliteus muscle and soleus muscle.After open reduction,anterolateral fractures and posterolateral fractures were fixed by the T-shaped plate and Golf shaped plate respectively.Results All of the 32 patients were followed up from 6 months to 36 months (in average of 15.3 months).Postoperative X-ray showed satisfied fractures without obvious collapse of the articular surface.At the last follow-up,the Rasmussen scores were range from 6 to 18 (in average of 14.06),namely 14 cases excellent,15 cases good,3 cases fair.The knee joint functions were evaluated according to HSS.The HSS results showed that there were 12 cases excellent,16 cases good,3 cases fair and 1 case bad.None of the cases suffered from injuries of crucial blood vessel or nerves.No incision necrosis,wound infection or fixation failure occurred during follow-up.Conclusion Open reduction and internal fixation via modified posterolateral approach can expose posterolateral and anterolateral tibial plateau fracture in one incision.Fibular head osteotomy can be avoided.The present approach could also reduce surgical injury,minimize the possibilities of incision necrosis or plate exposure.The modified posterolateral approach can be recommended in clinical practice.

Objective To analyse the clinical characteristics of infants in two months old of lingual thyroglossal duct cysts (LTGDC) and raise the levels of diagnosis and treatment.Methods A comparative analysis was made between the clinical data of 23 cases in two months old of LTGDC and those of 20 cases in one to seven years old of cervical thyroglossal duct cysts (TGDC) (control group).Results The clinical manifestation appeared obviously differences between LTGDC and TGDC.The main performance of LTGDC was laryngeal stridor,and 74％ of them went to emergency department because of dyspnea.They would be misdiagnosed as congenital laryngomalacia or laryngomalacia with pneumonia.The lesion located in the posterosuperior of lingual bone and behind the root of tongue,which was easy to lead to throat obstruction because it extruded laryngeal cavity.Electronic laryngoscopy was the first choice,it helped to identify laryngomalacia,epiglottis cyst and hemangioma.Laryngeal CT or MRI was very important to diagnose LTGDC which was quasi-circular low density shadow with clear boundary,or not extruded to laryngeal cavity,or show lesion range and surrounding structures avoiding misdiagnosis.As treatment depended surgery which was selfretaining laryngoscope,it was minimally invasive and without scar.Cervical anterior mass in the midline was the first symptoms in all 20 cases of TGDC.The neck ultrasound examination was the first selection,and the lesion showed fluid dark space with clear boundary,it should take the neck percutaneous surgical operation.Conclusion The clinical manifestation of infants in two months old of LTGDC appears obviously different from TGDC.LTGDC is a common cause of laryngeal stridor with breathing difficulties.It will be misdiagnosed as congenital laryngomalacia and lead to asphyxia or death easily.

Objective: To investigate the effects of ω-3 fish oil fat emulsion on nutritional status and humoral immunity in postoperative patients suffering from gastrointestinal malignancy. Methods: Thirty patients of gastrointestinal malignancy were randomly divided into study group (n = 15) and control group (n = 15). All the patients were assigned to receive total parenteral nutrition with the equal nitrogen and calory,and those in study group received fish oil fat emulsion additionally. Liver and renal function, blood lipid, haemoglobin, albumin, transferrin, total lymphocyte count (TLC) , B lymphocyte subsets (B1, B2), immunoglobin(IgG, IgM, IgA) and complement(C3, C4) were determined preoperatively and 1, 6d postoperatively. Results: There were no significant differences in liver and renal function and blood lipid on postoperative day 6 versus preoperation in all the two groups. TLC, IgG, IgM, C3 on postoperative day 6 were siginificantly higher in the study group(P < 0. 05). Haemoglobin, albumin, transferrin and B lymphocyte subsets were not significantly different between the two groups. Conclusion: Fish oil fat emulsion treatment was safe and tolerated, and could improve the humoral immunity in patients.

Objective To investigate the efficacy and safety of laparoscopic radiofrequency ablation (RFA) therapy for hepatocellular carcinoma.Methods Clinical data of 78 hepatocellular carcinoma patients undergoing laparoscopic radiofrequency in Beijing China-Japan Friendship Hospital from May.2008 to July.2010 were reviewed retrospectively.Age ranged from 31 to 87 years,41 were male and 37 were female.Intraoperative ultrasound-guided needle biopsy was performed and diagnosis of hepatocellular carcinoma was established in all cases before RFA was carried out.Data analysis was performed using software SPSS or OriginPro7.Necrosis,local recurrence of the tumor and the cumulative survival rate were analyzed by Kaplan-Meier test and x2 test.Results The median follow-up time was 16 months after RFA treatment.Tumor size,proximity to intrahepatic vessels and combination with TACE were factors that influence local recurrence.The complete ablation (CA) rate was remarkably higher in tumors ＜ 3 cm than in tumors ＞ 3 -5 cm (90.5％ vs 71.4％,x2 =4.291,P =0.038 ).Tumors adjacent to major vessels had a significantly lower CA rate as compared with those not adjacent to them (63.6％ vs 91.9％,x2 =6.351,P =0.012).The CA rate were 88.9％ in the TACE ± RFA group and 75.0％ in the RFA group ( x2 =1.567,P =0.211 ).The mean overall survival were 48.7 ± 2.4 months,the cumulative survival rate was 86.1％ at 1 year、76.9％ at 2 years、60.3％ at 3 years、51.8％ at4 years and 33.1％ at 5 years.Conclusions Laparoscopic RFA is safe,mini-invasive and effective for unresectable hepatic carcinoma with a favorable long term survival.
