The effects of ration level and feeding frequency on digestibility in juvenile soft-shelled turtle, Pelodiscus sinensis, were investigated. Four ration levels 1.5%, 2.5%, 4.0% and satiation (6.0% BW/d) were used. Apparent digestibility (AD) of dry matter (DMAD), protein (PAD) and protein real digestibility (PRD) were significantly affected by ration level, but not by feeding frequency when the ration level was similar. However, the feeding frequency affected the AD, DMAD, PAD and PRD significantly when the turtles were fed to satiation. The relationship between fecal protein content (Y) and protein intake (X) can be expressed as a quadric equation: Y=-0.1742+0.1476X-0.0003X(2) (r(2)=0.876, n=27, F=93.92, P<0.01).

Objective To observe the effect of traditional Chinese acupuncture-medcine on limb spasticity after stroke. Methods From April,2016 to October,2017,90 patients with limb spasticity after stroke were randomly divided into ba-sic rehabilitation group(n=30),baclofen group(n=30)and acupuncture-medicine group(n=30).All the groups accepted basic medical therapy and rehabilitation training,while the acupuncture-medicine group accepted acu-puncture at muscle tendon and Supplemented Peony-Licorice Decoction orally,and the baclofen group accepted baclofen orally.They were assessed with modified Ashworth Scale (MAS), simplified Fugl-Meyer Assessment (FMA)and modified Barthel index(MBI)before and four weeks after treatment,and the clinical effective rates were compared. Results The total effective rate of the basic rehabilitation group was 53.3%,and it was 66.7% in the baclofen group,and 86.7% in the acupuncture-medicine group.The scores of MAS,FMA and MBI significantly improved in all the groups after treatment(t>6.500,P<0.001),and improved the most in the acupuncture-medicine group(F>12.332, P<0.001).No adverse event was found during the treatment. Conclusion The integration of acupuncture and Chinese medicine in rehabilitation can further relieve the spasticity in pa-tients after stroke,and improve the motor function and activities of daily living.

OBJECTIVETo investigate the risk factors of prostate cancer in urban Qingdao and provide some theoretical evidence for the scientific prevention and treatment of the disease.

METHODSWe performed a hospital-based matched case-control study in Qingdao Municipal Hospital. The cases and controls were matched in age, gender, nationality and the place of residence. All the subjects were interviewed face to face in the hospital using a questionnaire, and the data analyzed by the conditional logistic regression method.

RESULTSAccording to the 258 valid questionnaires collected, the prostate cancer risk was significantly higher in the cases with a family history of cancer than in those without (OR = 2.58), and so was it in the men with the first spermatorrhea at the age of < or = 15 years than in those at the age of > or = 18 years (OR = 2.27). A decreased risk of prostate cancer was found among the men with the first experience of sexual intercourse between 25 to 30 years of age (OR = 0.76). An increased risk was shown in those with sexual intercourses > or = 4 times per week before 35 years old (OR = 2.57), masturbations > or = 3 times per week (OR = 2.30) and a drinking history (alcohol > or = 150 g/d) of > or = 10 years (OR = 2.83).

CONCLUSIONPositive family history of cancer, earlier age of the first spermatorrhea, sexual intercourses > or = 4 times per week before 35 years old, frequent masturbations, and heavy drinking for more than 10 years are risk factors for prostate cancer.

Objective: To explore susceptibility genes for autism spectrum disorders (ASD). Methods: Whole-exome sequencing was carried out for 60 family trios affected with sporadic ASD. Genetic variants discovered in over 10% of the patients were selected for genotype-phenotype correlation and pathway enrichment analysis using Phenolyzer software and metascape database. Combining gene-phenotypic scores, pathway-related genes associated with neural and neurite triggering were screened for the candidates. Results: A total of 170 common variants were found to be associated with the ASD phenotype. Among these, there was only one high-confidence gene [SHANK2 (0.8146)] and four medium-confidence genes [ERBB2 (0.1322), LAMC3 (0.1117), PPFIA4 (0.1059), DISC1 (0.1002)]. Twenty-pathways and four biological processes were found to be statistically significant by pathway enrichment analysis, which included neuron projection morphogenesis (GO: 0048812), regulation of neuroblast proliferation (GO: 1902692), modulation of excitatory postsynaptic potential (GO: 0098815), and dendrite morphogenesis (GO: 0048813). Twenty-one genes were found to be closely associated with neurological and neurite triggering, among which only SHANK2, ERBB2, and DISC1 had above-medium confidence correlation scores with the ASD phenotypes. Conclusion Abnormal neuron projection morphogenesis (GO: 0048812) may be closely related to the occurrence of ASD. SHANK2, ERBB2, and DISC1 are susceptibility genes for ASD.

The present study aimed to investigate the effect of proto-oncogene c-src on the viability of rat spermatogonial stem cells from 9 day-old rat in vitro. MTT method was used to observe the viability of the spermatogonial stem cells treated with antisense c-src oligodeoxynucleotides (ODNs) in vitro; RT-PCR was utilized to observe the expression of c-src mRNA and Western blot was used to observe the protein expressions of pp60c-src and phosphorylated signal transducer and activator of transcription-3 (p-STAT3). Compared with that in control group, the viability of spermatogonial stem cells decreased by 8.1% (P<0.05) and the expression of c-src mRNA decreased significantly after treatment with 10 μmol/L antisense c-src ODNs for 12 h. Compared with that in the control group, the protein expressions of pp60c-src and p-STAT3 decreased by 33.8% and 45.3% (both P<0.01), respectively, in the spermatogonial stem cells after being transfected with antisense c-src ODNs. The results suggest that proto-oncogene c-src regulates the viability of rat spermatogonial stem cells through p-STAT3.

Objective:To observe the clinical effect of acupuncture for persistent allergic rhinitis (PAR).Methods:A total of 154 PAR patients were randomized into a treatment group and a control group,78 cases in the treatment group received acupuncture at meridian points,while 76 cases in the control group received acupuncture at non-meridian points.The treatment was done every other day,3 times a week for a total 4 weeks.The total nasal symptom score (TNSS),the total non-nasal symptom score (TNNSS) and the rhinoconjunctivitis quality of life questionnaire (RQLQ) were measured before the treatment and after 2 weeks and 4 weeks of treatment,as well as 1 month and 3 months after the treatment to compare the clinical effect between the two groups.Results:After 4 weeks of treatment,the total effective rate in the treatment group was 92.3％,versus 76.3％ in the control group,showing a statistically significant difference (P＜0.05).Intra-group comparisons of TNSS,TNNSS and RQLQ scores after 4 weeks of treatment showed statistically significant differences (all P＜0.05).Between-group comparisons of TNSS,TNNSS and RQLQ score after 4 weeks of treatment and in follow-up visits showed statistically significant differences (all P＜0.05).Conclusion:Acupuncture is effective for PAR,and acupuncture at meridian points can produce a better effect than acupuncture at non-meridian points.

OBJECTIVETo investigate the effect of tea polyphenols on the proliferation of human prostate cancer cells and its possible mechanism.

METHODSWe cultured androgen-independent prostate cancer DU145 cells in the medium with different concentrations (50, 100, 250 and 500 microg/ml) of tea polyphenols, and those in the normal medium as the control. After 48 hours of culture, we detected the survival rate of the cells by MTT assay and determined the expression of survivin by Western blot and quantitative RT-PCR.

RESULTSAt 48 hours, the survival rates of the prostate cancer DU145 cells were 0.97 +/- 0.12, 0.71 +/- 0.07, 0.20 +/- 0.03 and 0.08 +/- 0.01 in the 50, 100, 250 and 500 microg/ml tea polyphenols treatment groups, all significantly reduced as compared with the control group (P < 0.01) except that of the 50 microg/ml group (P = 0.42). Furthermore, the survival rate continued to decrease with the prolonging of time, dropping below 5% at 96 hours except in the 50 microg/ml group. The grey values of the survivin expression in the 100, 250 and 500 microg/ml tea polyphenols groups were 13 425 +/- 34, 2 017 +/- 24 and 1 274 +/- 22, respectively, at 48 hours, significantly lower than 15 075 +/- 48 in the control group (P < 0.01). Moreover, the content of survivin mRNA at 48 hours was markedly lower in the 50, 100, 250 and 500 microg/ml treatment groups (0.74 +/- 0.03, 0.64 +/- 0.02, 0.52 +/- 0.01 and 0.21 +/- 0.02) than in the control (P < 0.01).

CONCLUSIONTea polyphenols can inhibit the proliferation of human prostate cancer DU145 cells, which may be associated with the decreased expression of the survivin gene.
