0.05). Conclusions Biofeedback and pelvic electric stimulation could be used to treat stress incontinence. Menopause status,BMI and severity of stress incontinence can not obvious affect the outcomes of biofeedback and pelvic electric stimulation.

0.05). ConclusionThe expression of VOCC mRNA and BKCa mRNA in kidney tissues of IgA nephropathy patients are abnormal.There is positive correlation between the abnormal expression of VOCC mRNA and BKCa mRNA and total glomerular pathological lesions integrals.The expression of VOCC mRNA and BKCa mRNA in kidney tissues of IgA nephropathy may serve as the indictor for the disease progression.

Objective To analyze the clinical, endoscopic and histopathological features of eosinophilic gastroenteritis ( EG) in children. Methods A retrospective study of 76 children with EG was performed to analyze clinical symptoms, laboratory and imaging results, endoscopic and pathological features, status of Helicobacter pylori ( H. pylori) infection, treatment and outcomes. Results The main clinical symptoms were abdominal pain in 55. 3%(42/76) cases, vomiting in 39. 5% (30/76) cases and hematochezia in 38. 2% cases( 29/76) . The hemoglobin level decreased significantly in 34 cases ( 44. 7%, 34/76). Peripheral blood eosinophil (EOS) count increased significantly in 9 cases (11. 8%,9/76) and EOS percentage increased significantly in 13 cases(17. 1%,13/76). Total serum IgE elevated in 32 cases ( 54. 2%, 32/59 ) . There were also 18 cases ( 36. 7%, 18/49 ) positive in serum allergen?specific immunoglobulin E ( sIgE) test and 25 cases ( 32. 9%,25/76) positive in fecal occult blood test. Among 51 cases of abdominal ultrasound examination, there were 7 cases of ascites, 4 cases of pelvis fluid and 3 cases of intestinal wall change. Endoscopic examination in 76 cases showed 63 cases ( 82. 9%) of mucosal hyperemia/edema,20 cases ( 26. 3%) of ulceration, 17 cases ( 22. 4%) of erosion, 11 cases ( 14. 5%) of nodularity or hyperplasia and 9 cases ( 11. 8%) of normal mucosa. The pathological examination showed mucosal inflammation with a large number of EOS infiltration(≥20 per HPF).There were 12 cases(15. 8%, 12/76) of H. pylori infection. Among the 76 cases, clinical symptoms improved significantly in 74 patients after treatment with dietary allergen avoidance, anti?allergy medications, antacids, montelukast and corticosteroid, and the total efficacy was 97. 4%. The efficacy of dietary allergen avoidance, anti?allergy medications, antacids and montelukast was 93. 8%( 61/65 ) . The efficacy of corticosteroid was 86. 7%(13/15). Conclusion The clinical manifestations and endoscopic characteristics of EG in children lack specificity. In terms of diagnosis, the elevated total serum IgE and the positive sIgE test may be taken as reference for the diagnosis of EG. The definite diagnosis is based on pathological examination ( EOS infiltration≥20 per HPF).While in terms of treatment, dietary allergen exclusion, anti?allergy medications, antacids and montelukast are highly effective, which can be taken as the first option. There is no need of corticosteroid as routine therapy.

To discuss clinical diagnosis and treatment of cow’s milk protein allergy and cow’s milk protein-induced FPIES (food protein induced enterocolitis syndrome). Methods We retrospectively analyzed clinical data of one infant with milk protein allergy-induced FPIES. Results A 67 days old female on mixed breast and formula feeding developed recurrent diarrhea, abdominal distension, vomiting, mucousy and bloody stools, feeding dififculty, anemia, and failure to thrive since 2 weeks after birth. Laboratory studies showed anemia, increased CRP level and elevation of peripheral white blood count and eosinophil proportion. Milk-speciifc IgE was negative. She was previously hospitalized 4 times, all with admitting diagnosis of“necrotizing enterocolitis”. We treated her with milk protein elimination for 4 weeks and all symptoms were resolved. Milk protein re-challenge test was positive, consistent with clinical features of cow’s milk protein allergy-induced infant FPIES. Conclusions Cow’s milk protein allergy and cow’s milk protein-induced FPIES can present with non-speciifc and variable clinical symptoms and signs, and should be considered in the differential diagnosis.

OBJECTIVETo study the clinical feature and more reasonable diagnostic typing criteria for patients with liver failure.

METHODS13/21 cases of ALF, SALF with no past liver disease, 49/72 cases of with chronic hepatitis, and 23/73 cases ALF, SALF with liver cirrhosis, were analyzed respectively.

RESULTS1 ALF patients (1). There exist significant statistic differences in ALB, ALT, CHE in three ALF groups.(2). It had statistic differences in those patients with hepatic encephalopathy.(3). The prognosis of the patients with chronic hepatitis group (42.85 percent) was best than that of chronic cirrhosis (26.09 percent) and no past liver disease (15.38 percent). (2) In SALF patients (1). There exist significant statistic differences in ALB, GLO, ALT, AST, BDIL, GLU and CHE in three SALF groups.(2). It had statistic differences in those patients with hepatic encephalopathy in three SALF groups.(3). The prognosis of the patients with chronic hepatitis group (51.39 percent) was best than that of chronic cirrhosis (36.85 percent) and no past liver disease (33.33 percent).

CONCLUSIONThere are different clinic feature and prognosis in three ALF or SALF groups, so we suggest that it were clinic practicability and science in classify of liver failure at present.

BACKGROUNDThe CRF07_BC recombinant strain has been one of the most predominantly circulated HIV-1 strains in China, it is therefore necessary and urgent to develop a relevant animal model to evaluate candidate vaccines targeting HIV-1 CRF07_BC. A highly replication-competent simian/human immunodeficiency viruses (SHIV) construct containing the Chinese CRF07_BC HIV-1 env gene with the ability to infect Chinese rhesus monkeys would serve as an important tool in the development of HIV vaccines. The aim of this study was to examine whether SHIV XJDC6431 with the env fragment from a Chinese HIV-1 isolate virus could infect the human and monkey peripheral blood mononuclear cell (PBMC), establish infection in Chinese rhesus macaque.

METHODSA SHIV strain was constructed by replacing the rev/env genes of SHIV KB9 with the corresponding fragment derived from the HIV-1 CRF07_BC strain. The infectious activity of the SHIV clones was determined in vitro in PBMCs from both non-human primate animals and humans. Finally, one Chinese rhesus macaques (Macaca mulatta) was infected with one SHIV via intravenous infusion.

RESULTSOne SHIV clone designated as SHIV XJDC6431, was generated that could infect macaque and human PBMC. The virus produced from this clone also efficiently infected the CCR5-expressing GHOST cell lines, indicating that it uses CCR5 as its coreceptor. Finally, the virus was intravenously inoculated into one Chinese rhesus macaque. Eventually, the animal became infected as shown by the occurrence of viremia within 3 of infection. The viral load reached 105 copies of viral RNA per ml of plasma during the acute phase of infection and lasted for 10 weeks post infection.

CONCLUSIONSWe conclude that SHIV XJDC6431 is an R5-tropic chimeric virus, which can establish infection not only in vitro but also in vivo in the Chinese rhesus macaque. Although the animal inoculated with SHIV XJDC6431 became infected without developing a pathologic phenotype, the virus efficiently replicated with a persistent level of viral load in the plasma. This suggested that the SHIV could be used as a tool to test candidate AIDS vaccines targeting the Chinese HIV-1 CRF_07BC recombinant strain.

Objective To report a large family with an autosomal dominant dementia associated with mutation in the prion protein gene(PRNP)and the detailed clinical,neuroimaging and pathological manifestations.Methods Two patients from a large family of dementia were admitted to our ward and the data of their medical history,physical examination,video electroenceplialogram,neuroimaging were colleted.A sterotactic biopsy of the right frontal lobe of the proband was done.After the informed consent from the family members obtained,the genomic DNA was extracted from peripheral blood leucocytes of 5 persons followed by in,vitro amplification using polymerase chain reaction(PCR).The PCR products were directly sequenced by Sanger method.PRNP gene sequence was also examined in 150 normal Chinese to exclude single nueleotide polymorphism.Results A missense mutation of PRNP gene in 5 farnily members was detected,resulting in Gll4V mutation in the prion protein,with M/M genotype of eodon 129.This mutation was not detected in 150 normal Chinese.The proband was diagnosed as inherited prion disease by her clinical features,including neuropsychiatrie disturbances and progressive dementia,and manifestations of neuroimaging,EEG,neuropathology and PRNP gene mutation.Conclusion The first autosomal dominant pedigree of family prion disease is found in China with G114V mutation in PRNP gene which may lead to the prion disease directly.

Background: Synaptic plasticity contributes to nociceptive signal transmission and modulation, with calcium/ calmodulin-dependent protein kinase II (CaMK II) playing a fundamental role in neural plasticity. This research was conducted to investigate the role of CaMK II in the transmission and regulation of nociceptive information within the nucleus accumbens (NAc) of naïve and morphine-tolerant rats. Methods: Randall Selitto and hot-plate tests were utilized to measure the hindpaw withdrawal latencies (HWLs) in response to noxious mechanical and thermal stimuli. To induce chronic morphine tolerance, rats received intraperitoneal morphine injection twice per day for seven days. CaMK II expression and activity were assessed using western blotting. Results: Intra-NAc microinjection of autocamtide-2-related inhibitory peptide (AIP) induced an increase in HWLs in naïve rats in response to noxious thermal and mechanical stimuli. Moreover, the expression of the phosphorylated CaMK II (p-CaMK II) was significantly decreased as determined by western blotting. Chronic intraperitoneal injection of morphine resulted in significant morphine tolerance in rats on Day 7, and an increase of p-CaMK II expression in NAc in morphine-tolerant rats was observed. Furthermore, intra-NAc administration of AIP elicited significant antinociceptive responses in morphine-tolerant rats. In addition, compared with naïve rats, AIP induced stronger thermal antinociceptive effects of the same dose in rats exhibiting morphine tolerance. Conclusions This study shows that CaMK II in the NAc is involved in the transmission and regulation of nociception in naïve and morphine-tolerant rats.
