Objective To explore the best way to diagnose and cure the nephrosis with ureteropelvic junction obstruction(UPJO) in children.Methods The diagnosis of 26 cases of nephrosis with UPJO were confirmed by ultrasonogram and IVU examinations.All patients underwent AndersonHynes procedures.These results were analyzed and summarized.Results All the diagnosis were proved to be correct by operation and pathology examinations,the operations were carried out successfully.Twenty-four cases were followed up for 6 months to 2 years.After the operation,the hematuria,urinary frequency,abdominal mass and distention disappeared,the urine analysis was normal,all cases cured clinically.Ultrasonogram examinations showed the thickness of parenchyma increased and the large kidneys lessened.Significantly improved renal fuoction on IVU examinations was observed in the 24 cases compared with that before the operations.The ureters of 20 cases displayed well.Conclusions The combination of ultrasonogram and IVU is very effective method to diagnose UPJO in children.Anderson-Hynes technique is the best procedure to cure the UPJO.

ObjectiveTo analyze the mental health level and the correlative factors of elderly reflux esophaditis patients.Methods86 elderly reflux esophagitis patients were tested with Symptom Check List-90 (SCL-90) and the Correlative Factor Inquiry List.ResultsThe total SCL-90 scores of the patients was 137.5±27, the number of symptomatic items was 29.9±17, which was significantly higher than that of domestic norm ( P<0.01). Besides of psychopathic and phobic, other factor scores of SCL-90 were also significantly higher than that of domestic norm ( P<0.05～0.01). The somatization, depression and anxiety were first three factors according to significant level. The constitution of patients showed the normal distribution at the level of total SCL-90 score.ConclusionMental health level of elderly reflux esophaditis patients is lower than that of normal people. The two primary reasons are long-term trend and stress of disease.

Background: Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are X?linked recessive neuromuscular diseases resulting from dystrophin (DMD) gene mutations. It has been known that the carrier of DMD mutations may also have symptoms of the disease. While de novo mutation is quite common in BMD/DMD patients, it is rarely reported in the female carriers. Methods: Two sporadic Chinese patients with progressive muscular dystrophy and their familial members were recruited. The targeted next?generation sequencing (NGS) and the multiplex ligation?dependent probe analysis (MLPA) were performed in the proband. Blood tests, electrocardiography, echocardiography, and electromyography were also evaluated. Results: Two novel mutations of DMD gene were identified, c.7318C>T(p.Q2440*) in the male proband and c.4983dupA(p.A1662Sfs*24) in the female carrier. The MLPA analysis did not detect any large rearrangements. The haplotype analysis indicated that the two mutations were derived from de novo mutagenesis. Conclusions: We identified two novel de novo mutations of DMD gene in two Chinese pedigrees, one of which caused a female patient with muscular dystrophy. The mutational analysis is important for DMD patients and carriers in the absence of a family history. The NGS can help detect the mutations in MLPA?negative patients.

OBJECTIVETo study the mechanism of reversal effect of Curcuma Wenyujin n-Butyl alcohol extract (CWNAE) on multiple drugs resistance (MDR) of SGC7901/VCR cells.

METHODSSGC7901/VCR cells were co-culured with different concentrations CWNAE (80, 40, and 20 μg/mL) and Verapamil (VP, 10 μg/mL) for 24 h, and then acted with Adriamycin (ADM) for 1, 2, and 4 h, respec- tively. SGC7901/VCR cells with no intervention were taken as the vehicle control group. SGC7901/VCR cells treated with ADM alone were taken as the control group. The effect of CWNAE on intracellular ADM concentration was detected by flow cytometry (FCM). Cells were treated as mentioned before without any intervention of ADM. SGC7901/VCR with no ADM intervention were taken as the control group. The effect of CWNAE on the expression of P-glycoprotein (P-gp), lung resistance protein (LRP), and glu- cosylceramide synthase (GCS) was studied by Western blot. The effect of CWNAE on the location and expression quantity of P-gp was further illustrated by immunohistochemistry (IHC).

RESULTSCompared with the ADM group, the expression ratio obviously increased in the W80, W40, W20, and VP10 groups with statistical difference (all P < 0.05). The comparative expression quantity of P-gp, GCS, and LRP in SGC7901/VCR cells was obviously higher than that of non-MDR with statistical difference (all P < 0.05). The expression quantity of P-gp and GCS could be obviously down-regulated by 80 and 40 μg/mL CWN- AE, and 10 μg/mL VP, with no effect on the expression of LRP. Results of IHC proved that P-gp was mainly expressed on the cytomembrane or in the plasma, and it was also expressed on the nuclear membrane. P-gp in different locations could all be down-regulated by CWNAE.

CONCLUSIONSCWNAE could reverse the MDR of SGC7901/VCR cell line probably by inhibiting the expression of P-gp and GCS. CWNAE had no effect on LRP that also highly expressed on SGC7901/VCR. So we supposed that CWNAE could become a potential drug to reverse MDR of highly expressed P-gp and GCS.

OBJECTIVETo investigate the efficacy of a 96-week course of nucleos(t)ide analogue and interferon (IFN) combination therapy for achieving seroconversion at 24 weeks after completion in patients with chronic hepatitis B (CHB).

METHODSOne-hundred-and-thirty-five CHB patients with positivity for hepatitis B e antigen (HBeAg) were recruited for study between January 2005 and December 2008. All patients were given a 96-week course of nucleos(t)ide analogue (lamivudine or adefovir dipivoxil) alone (monotherapy controls, n = 45) or in combination with IFN or Pegylated-IFN-alpha-2a (Peg-IFNa-2a) (n = 90). At treatment weeks 12, 24, 48, 72, and 96, and at 24 weeks after treatment completion, serum samples were collected from all patients for assessment of biochemical, virological and serological responses to treatment. The biochemical response was indicated by normalization of the alanine aminotransferase (ALT) level. The virologic response was indicated by a reduction in the hepatitis B virus (HBV) DNA level to less than 1000 copies/ml. The serological response was indicated by seroconversion of either HBeAg or hepatitis B surface antigen (HBsAg). Statistical analysis was performed with the Chi-squared test.

RESULTSAmong the patients treated with nucleos(t)ide analogue and IFN combination therapy, 41.1% (37/90) achieved HBeAg seroconversion and 18.9% (17/90) achieved HBsAg seroconversion at the end of treatment. However, significantly less of the patients treated with nucleos(t)ide analogue monotherapy achieved HBeAg seroconversion and none achieved HBsAg seroconversion by end of treatment (33.3% and 0%, respectively; x2= 8.08, P less than 0.01 vs. the combination therapy group). Age stratification of the 17 HBsAg-seroconverted patients treated with combination therapy indicated that the HBsAg seroconversion rate was significantly higher in patients less than 30-years-old than those 30 and older (x2= 12.62 and 4.24, respectively, P less than 0.05). At post-treatment week 24, the 17 HBsAg-seroconverted patients treated with combination therapy showed HBsAg titers of less than 250 IU/ml; moreover, 11.8% (2/17) of these patients remained HBeAg-positive and 17.6% (3/17) showed abnormal ALT levels and elevated HBV DNA.

CONCLUSIONProlonged nucleos(t)ide analogue plus IFN combination therapy can significantly improve the rate of HBsAg seroconversion in HBeAg-positive CHB patients, and this treatment regimen is especially efficacious in patients under the age of 30.

Genechip was applied to explore gene expression profile of islets in rats at various stages of pregnancy. Compared with the normal control group, differential expressions of hundreds of genes were detected during pregnancy. Reg3α gene expression was markedly increased during pregnancy, which may be related to islet regeneration.

Type 2 diabetes can be treated by gastrointestinal surgery, but the underlying mechanism is unclear. This review summarizes the possible mechanisms which include weight loss, gastrointestinal hormones, foregut hypothesis, hindgut hypothesis, adipocytokines, and inflammatory factors.
