Early-onset scoliosis (EOS) orthopedic treatment is a worldwide problem in recent years.With the growing rod technique clinical application and development of innovative,it has opened up a new way of orthotics for scoliosis.This paper reviews the development process of growing rods in treatment of early onset scoliosis.

Objective To analyse the clinicopathological changes of Alport syndrome (AS) and to detect the deposition of type Ⅳ collagen within basement membrane of Alport patients. Methods Fourteen patients with AS (12 families) hospitalized from 1990. 1 to 1996. 6 were investigated. Eleven were male and 3 female (mean age 29. 4 years). Results Microscopic hematuria was found in 13, with recurrent gross hematuria in 7. All had proteinuria. Three patients presented nephrotic syndrome. Progressive renal failure occured in 10 of 11 male(11 - 39 years) and 1 female (40 years). Six patients were treated with hemodialysis, two of them with transplantation. Sensorineural deafness was observed in 9 patients particularly high frequency sound. Anterior lenticonus were presented in 2. It showed heterogeneitic, 50% transmitted as X-linked dominant(XD) trait. In 7 renal biopsies, the findings by light microscopy mostly revealed focal and segmental sclerosis glomerulonephritis (4/7). The results of immunofluorescenc e (IF) were ne gatt ye in 4. Ultrastructural studies showed variable thickening, thinning of glomerular basement membrane (GBM) in 7 specimens with lamellation and basket-weaving of GBM in 1. Using the iIF technique, the ?3, 4, 5 (Ⅳ) chains were absent within both GBM and EBM of 4 male XD-AS patients. Conclusions AS is not a rare hereditary disease characterized by hematuria, proteinuria and progressive renal failure with sensorineural deafness and ocular lesions. Type Ⅳ collagen within Alpori patients' basement membrane is abnormal and iIF study of type Ⅳ collagen chains distribution is useful to confirm the diagnosis of AS.

Objective To know the situation of smoking control in all kinds of restaurants and the attitudes of citizens toward it.Methods Using methods of spot field investigation and questionnaire survey,193 of restaurant staff and 189 customers in 353 restaurants & bars were investigated.Results The average ratio of smoking control of all sorts of restaurants and bars was both about 25%,and in west restaurants,the average ratio of smoking control was 39.2%.Both the customers and the restaurants keepers were consistent on smoking control;the average supporting rate was 72.1%.Conclusion With the opportunity of Beijing 2008 Olympic Games,It is urgent for us to expand propaganda against smoking,and to strengthen non-smoking legislation and make out feasible smoking control measures for this city.

Objective To understand the awareness and attitude about no smoking among citizens in Public Places for Olympic game.Methods 20 spots were selected at random in Qinhuangdao city,and with convenience nonrandom sampling methods,the 30 earlier encountered citizens in every spots were investigated with questionnaire in the morning(6:30-7:30),noon(11:00-12:00) and the afternoon(16:00-17:00) during October 15 to 21,2007.600 pieces of questionnaires were distributed while 528 of them were received.The data were analyzed by Chi Square Test with the software EXCEL.Results The awareness rate of the non-smoking in the Public Places was 93.70% among citizens in core area,87.34% in sub-core area,and 72.93% in the peripheral area(?2=1276.07,P

Objective To explore the feasibility, safety and the efficacy of peroral endoscopic myotomy (POEM) for pediatric patients with achalasia.Methods A total of 21 patients (mean age 2 years, range 11 months-7 years) with AC were enrolled and underwent POEM from January 2012 to December 2014.Procedure-related complications, reflux esophagitis were observed.Eckardt score and the pressure of the lower esophageal sphincter (LES) were analysed.Results All patients underwent POEM successfully.No serious POEM-related complications were observed.During a mean follow-up period of 20.4 months (range 9-36 months), mean Eckardt score decreased from 8.1 to 0.8 after treatment (P ＜ 0.01).Mean LES treatment also decreased from 30.2 mmHg to 11.5 mmHg after the operation (1 mmHg =0.133 kPa, P ＜ 0.01).Reflux esophagitis developed in four patients (19.0％ ,4/21).Conclusion POEM is safe and effective treatment for pediatric patients with achalasia.

Pancreatic cancer is one of the most malignant tumors with a high mortality rate attributed to its widespread metastasis.A number of cellular signal transduction pathways involved in multiple genes play an important role in regulating this complex metastatic cascade of pancreatic cancer.NF-kappa B is one of the crucial signaling pathways.Studies has indicated that NF-kappa B could modulate a series of biological events relevant to tumor progress by controlling multiple targeted genes expression,such as cell proliferation,anti-apoptosis,angiogenesis,epithelial-mesenchymal transition,inflammation,stress response,etc.Furthermore,it can also up-regulate Hedgehog and MMPs signaling pathways.To help us better understand the potential mechanism and identify more sensitive tumor markers and selective targets,this review will underline the significant roles of NF-kappa B signaling pathway in regulatory network of pancreatic cancer metastasis.

This paper analyzes library users' satisfaction about service quality of the library of Peking University School and Hospital of Stomatology.The main factors associated with users' satisfaction are discussed.In the end,it proposes a series of effective measures to promot library service quality.

Objective To study the clinicopathological features and prognosis of Gastric hepatoid adenocarcinoma (GHA) and aims to guide future clinical practice.Method We retrospectively studied the clinical data of 25 patients with pathologically confirmed GHA who were admitted to our hospital from January 2003 to December 2015.Results There were 19 males and 6 females.The average age was 61.2 years.The clinical manifestations were non-specific.Pathologically,majority of GHA presented with ulcerative type,poor differentiation and extensive vascular cancerous embolus.Preoperative liver metastases were found in 12 patients,and postoperative liver metastases in 15 patients.Conclusions GHA is a special primary gastric adenocarcinoma which possesses both hepatocellular carcinoma-like and adenocarcinoma-like histology.GHA is characterized by a significantly elevated serum AFP and early hepatic metastasis.GHA is therefore often misdiagnosed as primary hepatocellular carcinoma.The main treatment option remains to be surgical resection,and the prognosis is poor.

At present,all parts of our country and the units are on their own to explore the ways and methods of public health physician training,and to develop a unified national public health standardized training system is particularly important.This study introduces the composition and practice of British public health specialist training and its access system,draws on the successful experience of this system and puts forward some suggestions such as paying attention to the cultivation of clinical basic knowledge,rationally using industry associations and societies and so on from the public health doctor training system,which provides the basis for promoting the establishment of a national public health physician training system.

Objective To investigate the influencing factors related to the complications of esophageal foreign body in children. Methods Data of 150 children with esophageal foreign bodies admitted to Xi'an Children' s Hospital from January 2012 to June 2015 were included in the retrospective analysis. Related clinical variables ( gender, age, location, time, size, sharpness, quality, and severity of complications) were statistically analyzed. Results Spearman correlation analysis showed that the age of children was negatively correlated with esophageal foreign body complications (r=-0. 187, P=0. 022), incarceration time ( r=0. 456, P<0. 001) , sharpness ( r=0. 384, P<0. 001) and quality ( r=0. 234, P=0. 004) was positively correlated with the incidence of complications. Non?conditional Logistic regression analysis for polytomous ordinal response showed that incarceration longer than 8 h yielded complication risks 9. 507 times as much as that less than 8 h ( 95%CI:2. 982?30. 309) . Obtuse or sharp foreign body yielded risk 142. 751 times as smooth foreign body did (95%CI:13. 736?1483. 562). Conclusion Incidence and severity of complications of esophageal foreign body in children are closely related to the age of the children, incarceration time and the degree of sharpness. For patients of less than 1 year old, incarceration for more than 8 hours, with an obtuse or sharp foreign body, early diagnosis and treatment is essential.
