Objective To investigate operative methods and indications for the surgical repair of hypospadias. Methods Clinical data of 91 cases of hypospadias repaired in this hospital between 1997 and 2003 were retrospectively analyzed. Results Postoperative urethral fistula took place in 15 cases, with an overall incidence of 16 5% (15/91), including 6 cases treated by Duckett procedure, 4 cases treated by Duckett combined with Duplay procedure, 1 case treated by Mathieu procedure, 2 cases treated by scrotal island flap procedure (Onlay procedure), 1 case treated by Denis-Browne procedure, and 1 case treated by Snod-grass procedure. Conclusions For patients with hypospadias associated with serious chordee, because the urethral plate can not be preserved, adaptable methods should include scrotal island flap procedure, Duckett procedure, or Duckett procedure combined with Duplay procedure. Urethral plate conserving operations are suitable for hypospadias without chordee or with mild chordee, involving the Mathieu procedure, Onlay procedure, Snod-grass procedure and Denis-Browne procedure.

Objective:To investigate the long-term efficacy of oral appliance treating of obstructive sleep apnea and hypopnea syndrome (OSAHS) in different periods of treatment.Methods:A total of 55 patients were included in the study.Patients were all diagnosed with OSAHS by overnight polysomnography and all received oral appliance (OA) as the therapy.The OA positioned the mandible at 60％-70％ of the maximal mandible advancement position and created a 4-5 mm incisor separation.The patients were instructed to wear the appliance during sleep,6-8 hours per day,for 5-7 days per week.They were divided into four groups by the period of treatment,including less than 1 year group;1-2 years group;2-6 years group and 6-9 years group.The polysomnographic study was used to investigate the efficacy of the four groups.The outcome measures included the score on the apnea-hypopnea index (AHI),the longest apnea time and the lowest oxygen saturation (LSaO2) levels during an overnight sleep.Results:The AHI decreased significantly in all the four groups.The less than 1 year group decreased from 24.50 (14.65,54.05) to 7.40 (2.12,10.00) events/h (P ＜ 0.001);The 1-2 years group decreased from 19.50 (12.15,39.23) to 1.80 (0.70,6.58) events/h (P =0.001);The 2-6 years group decreased from 25.00 (11.41,42.60) to 4.50 (1.35,7.90) events/h (P =0.001);The 6-9 years group decreased from 26.2 (16.95,47.45) to 4.00 (1.90,26.70) events/h (P =0.043).The longest apnea decreased significantly in less than 1 year group,1-2 years group and 2-6 years group.The longest apnea decreased from 57.00 (37.70,61.50) to 25.00 (15.90,33.50)seconds (P＜0.001) in the less than 1 year group,from 41.00 (25.50,62.26) to 13.10 (0.00,22.10) seconds (P =0.001) in the 1-2 year group and from 42.50 (30.35,58.15) to 15.60 (0.00,28.10) seconds (P =0.003) in the 2-6 year group.The LSaO2 levels increased significantly in the less than 1 year group and 2-6 years group.The LSaO2 levels rose significantly in the less than 1 year group,from 74.18％ ±7.96％ to 84.06％ ±7.67％ (P =0.001),and in the 2-6 years group,from 76.71％ ± 10.98％ to 84.06％ ±4.64％ (P =0.006),The LSaO2 levels did not increase significantly in the 1-2 years and 6-9 years groups.Kruskal-Wallis test showed that there were no statistically significant differences in the AHI,longest apnea time and LSaO2 in 4 the groups.Conclusion:The oral appliance is an effective therapy for patients with OSAHS in the long-term treatment.However,it's recommended to make appointments with patients as a follow-up supervision whether there is any efficacy decrease.And the oral appliance should be replaced if necessary.

Objective To study physiological foundation of acupunctureDeqi.Methods 28 healthy volunteers who never experienced acupuncture were recruited. The right Zusanli (ST36) and a site 1.5 cm beside Zusanli (ST36) (nominated as A) were acupunctured at different time. Shallow and deep acupuncturing was inserted at Zusanli (ST36). Only deep acupuncturing was inserted at A. Hemodynamic parameters of the anterior tibial artery including the peak value in the systolic phase (Vmax), the average blood flow velocity (Vm), and the inner diameter of vessels (Dist) were observed with colored Doppler ultrasound before, at the end of acupuncture, and 3 min afterDeqi response. Results There was significant difference in those parameters between before acupuncture and 3 min after deqi response when deep acupuncturing at Zusanli (ST36) (P＜0.05), but was not significant difference when shallow acupuncturing (P＞0.05). There was significant difference in ΔVmax and ΔVm between acupuncture at Zusanli (ST36) and A points (P＜0.05). Conclusion Arterial haemodynamics variation seems to be associated with acupunctureDeqi.

Disease bio-banks are an important strategic resource for medicine development. Such a bank with complete information and high information sharing enhances the competitiveness of medicine and promote the development of translational medicine. The present development of such banks is found with such setbacks as weak government leadership and standardization, as well as lack of a sharing mechanism. Therefore medical institutions should strengthen their standardization and informationization of disease bio-banks, which deserve sufficient government policy support and guidance. These efforts will help preserve our rich clinical resources, in addition to their integration and sharing for medicine advancement.

BACKGROUND: The expression of Fas antigen and P53 protein in colorectal cancer could reflect the biological character and the prognosis of the tumor.OBJECTIVE: To investigate the relationship between the expression of Fas antigen and P53 protein in coloreetal cancer and the tumor-related biological characters.DESIGN: A controlled experiment by introducing pathological specimens as subjects.SETTING: The study was conducted in the Department of Pathology of Xijing Hospital Affiliated with the Fourth Military Medical University of Chinese PLA.PARTICIPANT S: Totally 32 pathological specimens of colorectal cancer were randomly selected from the Department of Surgery of Xijing Hospital between January 1995 and October 1998. Sixteen normal large intestine tissues were selected form the cadaver of pathology department.METHODS: The expression of Fas antigen and P53 protein in 32 colorectal cancer tissue and 16 normal intestine tissue were tested and compared with immunohistochemical method.MAIN OUTCOME MEASURES: Fas antigen and P53 protein expression in coloreetal cancer and normal intestine, and the clinical indicators of patients with colorectal cancer.RESULTS: The expression of Fas antigen was positive in normal large intestine tissue while the expression of P53 protein was negative. The positive rate of Fas antigen expression in colorectal cancer was 41% (13/32), while the positive rate of P53 expression in colorectal caner was 53% (17/32). Fas antigen significantly decreased in colorectal cancer tissues. The expression of Fas antigen was correlated with the histological type of colorectal cancer and its liver metastasis( P ＜ 0.05) . And the expression of P53 protein was correlated with the liver metastasis of colorectal cancer( P ＜ 0. 05).CONCLUSION: The expression of Fas antigen significantly decreases in colorectal cancer. The higher the malignance is, the more significant less the expression is. Fas antigen does not express in liver metastasis patients. P53protein had positive expression in colorectal cancer tissues, especially in patients with liver metastasis. The reduction and deletion of Fas antigen expression and the excessive expression of P53 protein indicate poor prognosis.

The purpose of this study is to evaluate the anti-aging effects and reveal the underlying mechanism of Scutellaria baicalensis Georgi ethanol extract (SBG) in D-galactose-induced rats. Fifty rats were randomly divided into five groups: vehicle control group, D-galactose group, and D-galactose combined with 50, 100, 200 mg x kg(-1) SBG. A rat aging model was induced by injecting subcutaneously D-galactose (100 mg x kg(-1)) for ten weeks. At the tenth week, the locomotor activity (in open-field test) and the learning and memory abilities (in Morris water maze test) were examined respectively. The urine was collected using metabolic cages and analyzed by high-resolution 1H NMR spectroscopy combined with multivariate statistical analyses. The SBG at doses of 50, 100 and 200 mg x kg(-1) treatments groups could significantly ameliorate aging process in rats' cognitive performance. The 50, 100, 200 mg x kg(-1) SBG regulated citrate, pyruvate, lactate, trimethylamine (TMA), pantothenate, β-hydroxybutyrate in urine favorably toward the control group. These biochemical changes are related to the disturbance in energy metabolism, glycometabolism and microbiome metabolism, which is helpful to further understanding the D-galactose induced aging rats and the therapeutic mechanism of SBG.

Objective To study the expression of E-cadherin( E-cad), p-catenin(β-cat) in labial salivary glands of patients with primary Sj(o)gren's syndrome (pSS) in order to explore their role in pathogenesis. Methods Biopsies of labial salivary glands were obtained from 52 patients with pSS and 30 healthy controls. The immunohistochemical staining was used to detect the expression of E-cad and β-cat. Anti-SSA and anti-SSB antibodies were measured. Semi-quantitative analysis was performed by image analysis software. Ultra-structural changes was used by electron-microscopic techniques. Results ① The area of expression, optical intensity and the accumulated optical intensity of the E-cad group [(2513±1086) μm2, 0.212±0.041, 566 ±297 ] were lower than normal controls. The expression level was reduced as the increase of lymphocyte infiltration focus. ② The area of expression, the optical density and the accumulated optical density of the β- cat group [(12 324±7883) μm2, 0.113±0.031, 566±297] was lower than those of the control group. The expression level was reduced as the increase of the lymphocyte infiltration focus. ③ The E-cad expression and the p-cat expression was positively correlated in the labial gland of patients with pSS. ④ Howev-er, there was difference in the expression of E -cad and β -cat between patients with positive SSA and negative SSA antibodies. Conclusion In salivary samples, the expression of both E-cad and p-cat in patients with pSS is lower than those of the controls. Anti-SSA/SSB antibodies are important parameters of pSS and they may be involved in the pathogenesis of pSS.

Objective: To analyze the clinical features and interleukin-10 receptor gene mutations in six infants with very early onset inflammatory bowel disease (VEO-IBD). Methods: Four girls and two boys with VEO-IBD admitted to Children's Hospital Affiliated to Capital Institute of Pediatrics from June 2016 to September 2017 were reviewed. The clinical data including general condition, clinical symptoms, laboratory tests, and colonoscopy and pathological results were collected and analyzed. Interleukin-10 receptor α subunit (IL-10RA) gene was examined in all patients. Results: Persistent diarrhea and fever were the most common symptoms and were found within 1 month after birth in all 6 patients. Anemia, oral ulcer or perianal lesions and growth retardation were common concomitant symptoms. All patients had colonoscopy examination and the results showed multiple ulcers affecting the colon with biopsies revealing acute and chronic inflammation. Three patients were found to have cryptitis and crypt abscesses. Gene sequencing revealed IL-10RA gene mutations in all six patients, including 3 cases with homozygous mutations (one with c.537G>A and two with c.301C>T) and 3 heterozygous mutations (paternal c.301C>T in all cases; maternal c.299T>G, c.350G>A and c.537G>A, respectively) . After conventional treatment, one got clinical and pathological improvement according to colonoscopy, three improved clinically, one worsened and died, and one died of septic shock secondary to intestinal perforation. Conclusions VEO-IBD is associated with IL-10RA mutation, usually with severe intestinal symptoms and significant extra-intestinal symptoms, as well as varied responses to conventional treatment. In our study, c.301C>T and c.537G>A are the most common mutations.

Objective: To analyze the clinical and genotypic characteristics of infantile inflammatory bowel disease (IBD). Methods: The age of onset, family history, clinical manifestations, and treatment effect were retrospectively analyzed in 39 infants (male 23 cases, female 16 cases) with IBD who were admitted to the Department of Gastroenterology in Children′s Hospital, Capital Institute of Pediatrics from January 2007 to December 2017. Next generation sequencing (NGS) based on target gene panel was used for gene analysis in 17 patients. Results: The median age of onset was 0.5 (0.5, 1.0) month. The most common clinical symptoms included diarrhea (39, 100%), malnutrition (38, 97%), hematochezia (34, 87%), fever (25, 64%), and perianal diseases (24, 61%). Four children had associated family history. Among the 17 patients whose gene was analyzed, 10 were found to have the pathogenic gene variation, within whom 7 had interleukin-10 receptor α subunit (IL-10RA) mutation, 2 had CYBB heterozygous mutation, 1 had interleukin-10 receptor β subunit (IL-10RB) mutation. The therapeutic medicine included mesalazine, steroids, and thalidomide. Eighteen children (46%) reached clinical remission (10 cases) or partial remission (8 cases). Conclusions The incidence of single gene mutation in infants with IBD is high, with IL-10RA mutation as the most common. Refractory diarrhea and malnutrition may indicate infantile IBD.
