OBJECTIVETo establish a model of individually forecasting the penile length gained after penis lengthening.

METHODSA total of 322 patients were diagnosed congenital penile shortness and received partial suspensory ligament release in our department from Oct. 1988 to Apr. 2011. The patients were divide into two groups as Modeling Group (n = 200) and Checking Group (n = 122). Then a two-dimensional model of the suspensory-ligament-release penis lengthening is established. In the Modeling Group, a statistical analysis of the penile length in flaccid and erectile state before and after penis lengthening was carried out, and a forecasting predictive function of increased penile length was derived. Then the predictive accurate rate was tested in the Checking Group.

RESULTSThere was a significant linear correlation between the increased length in flaccid and erectile state (correlation coefficient = 0.921, P < 0.01), there was also a similar relationship between the extension rate of erection before and after the operation (correlation coefficient = 0.803, P < 0.01). According to the significant linear correlations showing above, two regression forecasting models were established. A predictive function of increased flaccid length was derived from the two regression forecasting models. The effectively forecasting rates were 84.5% (169/200, the Modeling Group) and 87.7% (107/122, the Checking Group) when the absolute value of forecasting error was less than 1.5 cm.

CONCLUSIONSThe discovered significant correlation and the established forecasting function provide us a model of roughly and individually forecasting the penile length gained after penis lengthening.

OBJECTIVETo provide theoretic warrant and technical reference for Salvia miltiorrhizr standardization planting, by carrying out various systemic studies such as observation of seeds configuration fabric, idiosyncrasy of water absorption and groping germinating conditions.

METHODIn the study of configuration fabric, seeds were observed and taken photos by scanning electronic microscope, and heft method was used for measuring changes of water absorption velocity and dehydration velocity. Seeds germination conditions were probed into under the national test regulations for crop seeds and related prescription from international standards.

RESULT(1) There was a layer of slime about 10-20 microm thickness covering epicarp of Danshen seeds. The slime formed as diamond meshwork (reseau) and the weight of it was 8%-10% of total seeds weight. (2) The speed of water absorption of seeds was extremely rapid. The weight of seeds could increase above 10 times as original while the dehydration velocity was quite low. (3) The optimal temperature for the seeds germination is around 25 degrees C, and the germination rate of the new seeds gained yearly was above 75%, but the rate would decrease sharply as years went by. It was also found that the seeds germination power and exponent of vigor were quite high under the temperature transformation between 23 degrees C, 28 degrees C. Such treatments as pre-cool, PEG treatment and infusing with GA3 could increase the rate of seeds germination capacity obviously.

OBJECTIVETo conduct an etiological molecular epidemiological survey and laboratory test on a foodborne disease epidemic outbreak to make clear of the cause and implement effective prevention and control on it.

METHODSOn May 12th 2012, 135 kindergarten children were sent to Xuzhou City People's Hospital and Children's Hospital with gastrointestinal infection disease. A total of 34 anus swab samples and 4 vomit samples were collected from the patients. Real-time PCR rapid detection, strains separation and cultivation, phage lysis experiments, ATB automated identification system were used to make etiological detection and identification. The genomic DNA of salmonella enteritidis were typed with the pulsed-field gel electrophoresis (PFGE), cluster analysis were carried out together with the patterns of local Salmonella infections.

RESULTSChildren in 20 classes were suffered from the gastrointestinal infection among the 21 classes. There were no significant aggregation of class distribution. Among the 135 patients, 76 were boys (56.3%) and 59 were girls (43.7%). The main symptoms were fever (above 38°C), diarrhea and bellyache. Through real-time PCR detection and strains separation, 19 salmonella enteritidis were isolated from 34 anus swab samples of suspected cases and the detection rate was 56%. There were no strains detected from vomit samples. All of the 19 salmonella enteritidis showed the same serological subtype, biochemical reaction, drug sensitivity and phage lysis pattern. The salmonella enteritidis had the identical PFGE pattern (100% similarity), and were different from the pattern of local sporadic infection cases.

CONCLUSIONIt was confirmed that this was an epidemic outbreak of foodborne disease caused by homologous salmonella enteritidis by epidemiological survey, clinical information, lab etiological test and molecular typing.

Helicobacter pylori (H.pylori) infection is a recognized risk factor of dementia,while its role and mechanism in Alzheimer disease (AD) remained unclarified.Our previous study has identified that injection of soluble H.pylori filtrate could induce AD-like pathologic changes and cognitive impairment in SD rats.In the present study,we further explored the effect of long-term stomach colonization of H.pylori bacteria on the brains of SD rats.The results showed that H.pylori bacteria gavage induced an efficient colonization of H.pylori in the stomach after four weeks.However,there was no significant change of tau phosphorylation at Thr205 (pT205),Thr231 (pT231),Ser396 (pS396) and Ser404 (pS404) sites in the hippocampus and cerebral cortex.The H.pylori-infected rats also showed no cognitive impairment.These observations may result from inefficient release of bacterial pathogenic factors or the overall lack of host inflammatory responses.We conclude that SD rat with long-term H.pylori colonization in the stomach is not a suitable animal model for exploring the effects of H.pylori infection on brain function in human beings;administration of bacterial filtrates may better reveal the systemic pathologic changes induced by bacterial infection in animals which show a negative host response to bacterial colonization.

OBJECTIVETo explore novel pathogenic mutation in the mitochondrial DNA gene in diabetic pedigree.

METHODSTwenty-eight suspected mitochondrial DNA diabetic families were recruited. The gene fragment was produced by PCR, and mutation was detected by direct sequencing.

RESULTSIn one pedigree, the proband and her mother were found carrying the most common nt3243 A --> G mutation and another 16S rRNA 3205C --> T mutation. But only 3205C --> T was found in her affected brother. All the two patients were deaf and developed diabetes in early age, characterized by impaired beta cell function and low body mass index (BMI). The proband had relatively higher lactic acid concentration than normal individuals. A novel ND1 gene 3434 A --> G(TAT --> TGT) mutation was explored in another proband with deafness and her affected family members.

CONCLUSION16SrRNA 3205C --> T mutation was found in a mitochondrial diabetes mellitus pedigree, implying its potential pathogenic role in diabetes. Another novel ND1 3434 A --> G mutation was found in another diabetic pedigree. Because this mutation causes amino acid change (Tyr --> Cys) and is co-segregated with diabetes, it may be diabetogenic.

The efficacy and safety of bevacizumab with modified irinotecan, leucovorin bolus, and 5-fluorouracil intravenous infusion (mIFL) in the first-line treatment of metastatic colorectal cancer (mCRC) has not been well evaluated in randomized clinical trials in Chinese patients. We conducted a phrase III trial in which patients with previously untreated mCRC were randomized 2:1 to the mIFL [irinotecan (125 mg/m(2)), leucovorin (20 mg/m(2)) bolus, and 5-fluorouracil intravenous infusion (500 mg/m(2)) weekly for four weeks every six weeks] plus bevacizumab (5 mg/kg every two weeks) group and the mIFL group, respectively. Co-primary objectives were progression-free survival (PFS) and 6-month PFS rate. In total, 214 patients were enrolled. Our results showed that addition of bevacizumab to mIFL significantly improved median PFS (4.2 months in the mIFL group vs. 8.3 months in the bevacizumab plus mIFL group, P < 0.001), 6-month PFS rate (25.0% vs. 62.6%, P < 0.001), median overall survival (13.4 months vs. 18.7 months, P = 0.014), and response rate (17% vs. 35%, P = 0.013). Grades 3 and 4 adverse events included diarrhea (21% in the mIFL group and 26% in the bevacizumab plus mIFL group) and neutropenia (19% in the mIFL group and 33% in the bevacizumab plus mIFL group). No wound-healing complications or congestive heart failure occurred. Our results suggested that bevacizumab plus mIFL is effective and well tolerated as first-line treatment for Chinese patients with mCRC. Clinical benefit and safety profiles were consistent with those observed in pivotal phase III trials with mainly Caucasian patients.
