Objective To evaluate the value of small intestinal double contrast radiography ( SIDCR) in the diagnosis of small intestinal diseases. Methods The data of 1182 SIDCR cases have been reviewed, including patients' sex, age, clinical symptoms and final diagnosis. The positive rate of diagnosis and types of disease in SIDCR cases were analyzed. Results The positive rate of diagnosis by SIDCR was 41.46%. In all positive cases, diverticulum accounts for 27.14%, inflammatory diseases 19.80%, and tumor 12.45%. The positive rate in in-patients was 54.00%, and in out-patients was 31.84%. The positive rate of male was 42.22%, and that of female 40.43%. The highest positive rate was 48.21% in 51-60 years old age group. In terms of clinical manifestations, the positive rate was highest in patients with abdominal mass (63.15%), and followed by gastrointestinal hemorrhage (51.58%) and abdominal pain (48.61%) respectively. Conclusions At present, the SIDCR is still a reliable and useful tech- nology, and is one of main methods for the diagnosis of small intestinal diseases.

[Objective]To compare the differences in using Ponseti method treating congenital clubfoot (CCF) patients older than six-month and younger than six-month of congenital clubfoot(CCF). [Method]Five hundreds and forty-four feet in 378 cases of CCF were treated with Ponseti method. According to the age differences, they were divided into older infancy group (﹥6 month, 227 feet in 157 cases and younger infancy group(≤6 month,317 feet in 221 cases). The deformation degree of CCF was evaluated by the Pirani scoring system. A scoring of 0-0.5 was regarded as being excellent. For each group, we evaluated the percentage of excellence result according to the Pirani score, the number of casts used, and the percentage of percutaneous achillotenotomy. The result was compared between the two groups. [Result]The excellence rate showed no significant differences between the two groups (P﹥0.05). Both the number of casts used and the percentage of percutaneous achillotenotomy in the younger infancy group were more than that in the older infancy group. There was obvious difference between the two groups (P

Objective To evaluate the effect of cytokines in hematopoietic microenvironment on the pathogenesis of aplastic anaemia (AA)and its clinical significance Methods For the marrow and peripheral blood samples from 20 AA patients and 8 normal controls, the levels of granulocyte colony stimulating factor (G CSF) and tumor necrosis factor alpha (TNF ?) were determined with ELISA assay,the expression of CD31 and CD44 on the mononuclear cell were measured with immunofluorescence assay Results The level of G CSF and TNF ? in the marrow and blood were higher( P

Objective To summarize clinical imaging characters of the gastric lymphoma in gastroscopy and double contrast radiography of upper gastrointestinal tract.Methods We reviewed 24 cases of gastric lymphoma from January 1996 to June 2006 and analyzed their endoscopic and X-ray features,as well as their pathological results.Results The most frequently involved parts were gastric body(75%,18 cases) and antrum(67%,16 cases).The most common changes were: ①ulcer(71%,17 cases),especially multiple shallow ulcers which had different forms;②nodular protuberance(67%,16 cases),sometimes submucous giant protuberance;③giant duplicature(54%,13 cases);and ④involvement spreading along the gastrointestinal tract(21%,5 cases).Conclusions The characters of gastric lymphoma are ulcer,nodular protuberance,giant duplicature,and so on.The combination use of gastroscopy,radiography,endoscopic mucosal resection,endoscopic ultrasound,and laparoscopy is important for definite diagnosis.

Objectives To analyse the predisposing cause and clinical manifestasion of diabetic ketoacidosis (DKA) complicated with multiple organic failure (MOF),in order to diagnose early and management timely.Methods 537 diabetic patients admitted in our hospital from 1997 to 2000 were included in this cases retrospective study. 182 cases of them complicated with DKA or DKA complicated with MOF (58) were further analyzed by cause, clinical manifestation, number of organs in MOF and the prognosis. Results Analysis showed that the main cause of MOF in DKA patients was infection (84 5%). The higher incidence of MOF in older DKA patients than those of younger. The possible involved organs in MOF were kidney, heart and brain etc. Involving organs of MOF were much, the mortality was closely correlated with the number of involved organs. Conclusions The possible way to reduce the incidence of MOF in DKA patients is intensive preventing and treating infection. To avoid MOF occurring in DKA patients, complications of kidney, heart and brain should be timely diagnosed and managed.

Forty cases of unilateral low- frequency sensorineural hearing loss(LFSNHL) were analysed. The symptoms included tinnitus(87.5% ), deafness(75% ), vertigo(35%) and ear fullness(25% ). Audiome-try showed LFSNHL in all cases. The threshold difference between low frequencies and high frequencies was 26. 32 dB. The cause of LFSNHL, the relation between tinnitus, LFSNHL and endolymphatic hydrops were discussed. We hope that the diagnosis of LFSNHL should be standardized.

Objective To explore the diagnostic value of barium meal in gastroesophageal reflux disease(GERD).Methods The data of patients who performed barium meal from January 2003 to December 2012 were retrospectively analyzed,and the GERD detection rate and its relationship with gender and age were calculated and compared.The degree and position of reflux during barium meal in 454 patients in 2012 and the relationship between age and degree and symptom of reflux were studied.Results The GERD detection rate was 13.48％(2 743/20 353) from January 2003 to December 2012,and increased by years.The GERD detection rate in male and female were 13.73％(1 312/9 554) and 13.25％(1 431/10 799) respectively,and there was no significant difference (P ＞ 0.05).With the increase of age,the GERD detection rate increased aslo.In patients of age ≤30 years,31-60 years and ≥61 years,the GERD detection rate were 6.87％ (197/2 866),11.63％(1 096/9 421) and 17.98％(1 450/8 066) respectively,and there was significant difference (P ＜ 0.05).The mild reflux accounted for 242 cases,the moderate reflux accounted for 110 cases,and the severe reflux accounted for 102 cases in patients with GERD in 2012,and there was also an aggravating reflux degree with the increase of age.In patients ≤30 years,31-60 years and ≥61 years,the reflux degree were 10.26％(4/39),17.92％(38/212) and 29.56％(60/203) respectively (P ＜ 0.05).The position with left anterior oblique was most often,accounting for 95.37％(433/454).Conclusions Barium meal can be directly observed,and evaluate the degree of reflux and position.Barium meal is simple and intuitive,and can be used as one of GERD diagnostic methods.

0.05),after six weeks remission rates were 84.6% and 30.0%,respectively(P 0.05).Conclusions Interventional stent placement is recommended for patients with external compression IVC obstruction,with significant relief of the clinical symptoms and prolongation of the survival term.For embolic type of IVC obstruction patients,stenting is only a short-term palliative modality because of higher re-obstruction rate and shorter survival term.

OBJECTIVE To establish multiple PCR(M-PCR) assay for simultaneous detection of Treponema pallidum(TP) and herpes simplex virus(HSV),Haemophilus ducreyi(HD).METHODS According to specific gene sequence of the three agents:HSV DNA polymerse gene,TP tpp47 gene,HD 6s rRNA gene;three sets of specific primers were designed and a multiple PCR assay was developed to detect 3 agents in one test.RESULTS The target DNA of 3 agents were specifically amplified by their specific primers,the appropriate size of four DNA fragments was 202bp,252bp,152bp for TP,HSV and HD,respectively.The DNA of other several common microbes of genital tract and human genome could not be amplified by three sets of primers.CONCLUSIONS Primary study indicated that the M-PCR assay can simultaneously,specifically and rapidly detect out HSV,TP and HD.
