ObjectiveTo explore the effect of constraint-induced movement therapy on hemiplegia in children.Methods30 hemiplegia children caused by cerebral palsy or trauma were divided into 2 groups.Treatment group accepts the Constraint-Induced Movement Therapy (CIMT) combined with Bobath approach. The control group accepts the Baboth approach only. Before after 12-week treatment, Ueda Test and the Brunnstrom's test were used to classify every stage of the recovery. ResultsBoth groups improved their motor function assessed either with Ueda Test or Brunnstrom's test, which was better in treatment group than in control group.ConclusionThe CIMT with Bobath approach together can remarkably raise the rate of utilization of the hemiplegia suffering limbs as well as improve the learned non-use of the suffering parts.

Objective To explore the feasibility of detecting death-associated protein(DAP) kinase promoter hypermethylation in the tumor tissues and plasma of patients with gastric adenocarcino- ma,and to evaluate the effect of DNA hypermethylation and autofluroscene spectrums of gastric juice on diagnosing gastric carcinoma.Methods Primary tumor tissues and plasma and gastric juice of 50 patients with gastric adenocarcinoma were collected.Gastric mucosa tissue,plasma and gastric juice of 20 patients with chronic superficial gastritis and 20 patients with benign gastric ulcer and 30 patients with chronic atrophic gastritis were collected as controls.After sodium-bisulfite treatment,extracted DNA was amplified for DAP kinase promoter hypermethylation by methylation-specific polymerase chain reac- tion.At the same time the gastric juice autofluroscene spectrums(the excitation wavelength was 288 nm,whereas the range of emission wavelength was 300-800 nm)were detected.Results Among the samples from 50 patients,p16 and DAP kinase hypermethylation were detected in 74.4% and 68.1% of tumor tissues,52.0% and 58.0% of plasma,58.6% and 76.0% of gastric juice.No hypermethylation was detected in samples of chronic superficial gastritis and serum of patients with gastric ulcer.Among the patients with gastric ulcer,p16 and DAP kinase hypermethylation were detected in 10.0% and 20.0% of tissues,5.0% and 15.0% of gastric juice.Among the samples from 30 patients with chronic atrophic gastritis,p16 and DAP kinase were detected in 10.0% and 23.3% of tissues,3.3% and 3.3% of sera,3.3% and 20.0% of gastric juice.The intensity of gastric juice autofluroscence spectrums of patients with gastric carcinoma was much higher than those in controls.The sensitivity of p16 and DAP kinase hypermethylation and autofluorescence spectrums together were 95.6% and 97.8% respectively.Con- clusions Promoter hypermethylation of the p16 and DAP kinase gene detected in plasma and gastric juice consists with that in primary tumor tissues of patients with gastric adenocarcinoma.The combination of DNA hypermethylation and autofluorescence spectrum has a good future in diagnosing gastric carcinoma.

The study was aimed to examine the B cell activating factor promoter polymorphism of the TNF family (BAFF)-871 C/T in patients with immune thrombocytopenic purpura (ITP) and to explore its correlation with ITP and the relationship between the blood platelet count of newly diagnosed patients with ITP and genotypes of BAFF-871 C/T polymorphisms. Alleles specific polymerase chain reaction (ASP-PCR) and agarose gel electrophoresis were used to identify polymorphisms -871 C/T of BAFF promotor in 133 ITP patients and 117 healthy controls, and determine the genotype of subjects. Meantime, the frequency of genotype and alleles were analyzed. The results indicated that out of 133 patients with ITP, 33.1% patients exhibited C/C, 42.1% patients were heterozygous C/T, and 24.8% patients were homozygous T/T. The corresponding frequencies in 117 healthy controls were 55.6% C/C, 33.3% C/T and 11.1% T/T. The allele frequency of T in ITP patients and healthy controls were 45.9% and 27.4% respectively. There was significant difference in the BAFF-871 C/T genotypic frequency between the ITP patients and healthy controls (p < 0.05). The allele frequency of T in ITP patients was higher than that in healthy controls. There was no significant difference in the blood platelet counts between the various genotype (p > 0.05). It is concluded that the polymorphism -871 C/T of BAFF promoter is correlated with the pathogenesis of ITP. However, there is no significant difference in blood platelet counts between the various genotype, so the polymorphism -871 C/T of BAFF promoter can not be referred as the analysis index for evaluating the severity of ITP.

Objective:To explore the clinical characteristics of pancreaticobiliary maljunction (PBM) and its disease spectrum, and to evaluate therapeutic endoscopic retrograde cholangiopancreatography (ERCP).Methods:Data of 52 PBM patients who received therapeutic ERCP procedures for abdominal pain, jaundice and fever in Department of Gastroenterology of Peking University Third Hospital from June 2006 to March 2021 were collected. The clinical characteristics, typing, the change of disease spectrum and ERCP procedures were analyzed.Results:Among 52 PBM patients, female was more common. Abdominal pain and jaundice were the most common clinical manifestations, among which 20 were type Ⅰ, 25 type Ⅱ and 7 type Ⅲ. Half patients had the choledochal cyst. The mean timespan from the first onset to the final diagnosis was 12.2 years. Twenty-four cases (46.2%) had changes in PBM disease spectrum. Among 69 ERCP procedures, 5 (7.2%) failed. Difficult cannulation rate was 34.6% (18/52), and 11 patients underwent advanced cannulation techniques, while it was 15.4% (657/4 275) in the conterpart non-PBM patients in the same period, with significant difference between them ( χ2=14.455, P<0.05). Multiple therapeutic ERCP techniques including endoscopic sphincterotomy, pancreatic stent placement, removal of stones from the duct were applied with the successful rate of 92.8% (64/69). The incidence of post-ERCP pancreatitis was 15.4% (8/52). Conclusion:The chief clinical problem may be changed over time in PBM patients. Although ERCP plays an important role in PBM and its disease spectrum, there may be a higher rate of difficult cannulation and postoperative complications.

OBJECTIVETo evaluate the levels of bone morphogenetic protein-15 (BMP-15) in human follicular fluid (FF) and its association with response to ovarian stimulation.

METHODSWestern blotting was performed to determine the levels of BMP-15 in FF obtained from follicle aspirates in 70 patients undergoing IVF treatment. According to the response to ovarian stimulation the patients were divided into poor responder group and normal responder group.

RESULTBMP-15 levels in FF of poor responders were significantly higher than those in normal responders (1.01 +/- 0.34 vs 0.77 +/- 0.24, P<0.01).

CONCLUSIONIncreased levels of BMP-15 in FF may be associated with poor response to ovarian stimulation.

OBJECTIVETo investigate the expression of cathepsin D in ovary of patients with polycystic ovarian syndrome (PCOS).

METHODSWestern blot was performed to detect the expression of cathepsin D and immunohistochemistry was used to detect the protein distribution in ovarian tissue.

RESULTSemi-quantity values of cathepsin D expression in PCOS and control group were 2.06 +/- 0.39 and 4.76 +/- 1.43 (P<0.05), respectively. Immunostaining for cathepsin D was obvious in both follicles and stromal cells, and the strongest immunostaining was seen in granulosa cells of follicles. Immunochemical study showed the protein was mainly located on the cytoplasm and cell membrane.

CONCLUSIONCathepsin D expression is down-regulated in ovaries of PCOS patients, which may provide a clue for the abnormality of follicle development in PCOS.

OBJECTIVETo analyze the polymorphisms of B cell activating factor (BAFF) gene and the plasma levels of BAFF in patients with idiopathic thrombocytopenic purpura (ITP), and to investigate their roles in the pathogenesis of ITP.

METHODSAlleles specific polymerase chain reaction (AS-PCR) and agarose gel electrophoresis were used to identify polymorphisms -871C/T of BAFF promotor in 133 ITP patients and 117 healthy controls. The plasma levels of BAFF were assayed by ELISA.

RESULTSIn ITP group, the frequency of C/C, C/T and T/T was 33.1%, 42.1% and 24.8%, respectively, the corresponding frequency in control group was 55.6%, 33.3% and 11.1%, respectively. The allele frequency of T in ITP and control groups was 45.9% and 27.4%, respectively. There was a significant difference in the BAFF -871C/T genotypic frequency between the ITP and control groups (P < 0.05). BAFF antigen in untreated ITP, treated patients and controls was 875.86 pg/ml, 502.59 pg/ml and 736.88 pg/ml, respectively, being also a significant difference among the three groups (P < 0.05). BAFF antigen in homozygous T/T was higher than that in homozygous C/C and heterozygous C/T, but the difference was not statistically significant (P > 0.05).

CONCLUSIONSOver expression of BAFF may be a risk factor for ITP patients. There is a correlation of the BAFF promotor polymorphism -871C/T with ITP, but the polymorphism does not affect the expression of BAFF.

BACKGROUNDHelicobacter pylori (H. pylori) frequently colonizes the stomach. Gastroesophageal reflux disease (GERD) is a common and costly disease. But the relationship of H. pylori and GERD is still unclear. This study aimed to explore the effect of H. pylori and its eradication on reflux esophagitis therapy.

METHODSPatients diagnosed with reflux esophagitis by endoscopy were enrolled; based on rapid urease test and Warth-Starry stain, they were divided into H. pylori positive and negative groups. H. pylori positive patients were randomly given H. pylori eradication treatment for 10 days, then esomeprazole 20 mg bid for 46 days. The other patients received esomeprazole 20 mg bid therapy for 8 weeks. After treatment, three patient groups were obtained: H. pylori positive eradicated, H. pylori positive uneradicated, and H. pylori negative. Before and after therapy, reflux symptoms were scored and compared. Healing rates were compared among groups. The χ2 test and t-test were used, respectively, for enumeration and measurement data.

RESULTSThere were 176 H. pylori positive (with 92 eradication cases) and 180 negative cases. Healing rates in the H. pylori positive eradicated and H. pylori positive uneradicated groups reached 80.4% and 79.8% (P = 0.911), with reflux symptom scores of 0.22 and 0.14 (P = 0.588). Healing rates of esophagitis in the H. pylori positive uneradicated and H. pylori negative groups were, respectively, 79.8% and 82.2% (P = 0.848); reflux symptom scores were 0.14 and 0.21 (P = 0.546).

CONCLUSIONSBased on esomeprazole therapy, H. pylori infection and eradication have no significant effect on reflux esophagitis therapy.

OBJECTIVETo compare the expression of pinopodes, the marker of endometrial receptivity, during the implantation window in Kunming mice stimulated with two different doses of raloxifene (RAL).

METHODSForty-eight 8-week-old female Kunming mice were randomly divided into 4 groups (n=12), namely saline group, clomiphene citrate (CC, 18 mg/kg) group, RAL (33 mg/kg) group and RAL (44 mg/kg group). In each group, the mice received intragastric administration of 1 mL of normal saline containing CC or RAL at the specified doses or saline only as indicated for ovulation induction, once daily for 2 days. The mice received then injection with 5 IU human chorionic gonadotropin (HCG) and mated and on day 4.5 of gestation, the pregnant mice were sacrificed for examination of the uterus with scanning electron microscopy.

RESULTSAbundant and well developed pinopodes were observed in the endometrium of the mice in the 2 RAL groups and in the saline control group. The mice in CC group showed obviously reduced endometrial pinopodes with poor development.

CONCLUSIONSRAL at two different doses does not obviously affect the expression of pinopodes in the uterine epithelium of mice, suggesting the safety of RAL at these two doses for ovulation induction without causing adverse effects on endometrial receptivity.
