Objective To explore the effect of Shenling Baizhu Powder and moxibustion on serum brain-gut peptide in patients with diarrhea predominant irritable bowel syndrome (D-IBS). Methods Sixty D-IBS cases were randomly divided into two groups, 30 cases in the treatment group were given Shenling Baizhu Powder and moxibustion therapy, and 30 patients in the control group were given loperamide hydrochloride capsule. Treatment for the two groups lasted for 4 weeks. Clinical symptoms and serum brain gut peptide (5-HT, VIP and SP) levels of two groups were observed before and after treatment, clinical efficacy were evaluated. Results Markedly effective rate of the treatment group was 66.7% (20/30), better than 33.3% (10/30) in the control group (P<0.05). After treatment, clinical symptom scores of the treatment group decreased significantly (P<0.01), while only diarrhea and abdominal pain improved in the control group (P<0.01), with statistical significance (P<0.01). After treatment, serum 5-HT, VIP, and SP of the treatment group were decreased (P<0.01), while these indexes of the control group did not change significantly (P>0.05), with statistical significance (P<0.01). Conclusion Clinical efficacy of Shenling Baizhu Powder and moxibustion in treating D-IBS is better than that of loperamide hydrochloride capsule, and can significantly improve clinical symptoms and regulate serum brain-gut peptides levels.

This study was aimed to evaluate impacts on immune regulation with spleen-strengthening and kidney-tonifying method among advanced malignant tumor patients. The enrolled advanced malignant tumor patients were randomly divided into the control group and the treatment group. The control group was treated with conventional treatment plan. The treatment group was treated with spleen-strengthening and kidney-tonifying Chinese herbs on the basis of conventional treatment plan for three months. Clinical effect, integral of clinical symptom (ICS), T-lym-phocyte subsets, and drug safety index were observed and detected before and after treatment. The results showed that the effective rate and response rate in the control group were 31.1% and 71.1%, respectively. And the effective rate and response rate in the treatment group were 54.2% and 85.4%, respectively. The treatment group was better than the control group (P< 0.05). Compared to the control group, the treatment group had obvious regulation on T-lymphocyte subsets. The improvement on ICS in the treatment group was better than the control group (P < 0.05). There was no obvious adverse reaction with the application of Chinese herbs. It was concluded that the spleen-strengthening and kidney-tonifying method can improve clinical effect, life of quality, and reduce adverse reaction a-mong advanced malignant tumor patients. Its mechanism may be through the regulation of immune function.

OBJECTIVE: To analyze the results of hearing screening and the related factors in 3200 newborn infants, in order to know the incidence of neonatal hearing disorders. METHOD: Three thousand two hundred cases of newborn infants born during 2014-01 and 2015-03 were tested for hearing screening. According to risk factors, newborns were divided into the normal newborn group (2945 cases) and the high-risk neonatal group (255 cases). Using fast brainstem auditory evoked potential (AABR) to screen the hearing screening of newborn infants with 3~5 d; those who did not pass the screening, after the birth of 30~42 d re-screening; re-screening still not pass, within 3 months line diagnostic auditory brainstem evoked potential (diagnostic ABR) confirmed. Comparative analysis of newborn hearing screening by screening through rate, re-screening through rate and hearing impairment rate proportional relationship with the relevant factors, and the differences of hearing screening results in the normal newborn group and the high-risk neonatal group. RESULT: (1)The rate of neonatal hearing screening did not pass was 7.50% (240/3,200); 30 cases was not involved in re-screening, the rate of re-screening did not pass was 15.24% (32/210); hearing impairment rate is about 0.38%(12/3200), and the bearing impairment positive rate was 1.31% (42/3200). (2) There was no significant difference of different delivery mode, neonatal sex in newborn hearing screening through rate, re-screening through rate and hearing impairment rate (P > 0.05). Different gestational age, maternal age in newborn hearing screening through rate, re-screening through rate and hearing impairment rate, the difference was statistically significant (P < 0.05). (3) Screening through rate and re-screening through rate of the high-risk neonatal screening group were significantly lower than the normal newborn group (P < 0.05), and hearing impairment rate was higher than normal newborn group (P < 0.05). CONCLUSION Strengthen prenatal health care, to reduce abnormal childbirth conditions (preterm birth, neonatal asphyxia), universal newborn hearing screening and improve screening accuracy, and to strengthen newborns with risk factors for early diagnosis and intervention, to reduce the incidence of neonatal hearing impairment has important significance.

Objective To assess influence factors of imaging quality with 64-slice spiral CT angiography (CTA) of renal artery. Methods A total of 305 hypertension patients underwent CTA of renal artery, and 108 of them were examined with DSA. The imaging quality was classified as Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, and the degree of stenosis wass classified as <50%, 50%-74%, 75%-99% and occlusion. The sensitivity and specificity of CTA of renal artery was analyzed taking DSA as the standard. Results The influence factors of CTA of renal artery included the delayed time set, rotation time, the units dose of contrast medium and the speed of injection, breath-holding, the patients age and vascular calcification. The sensitivity and specificity of CTA of arterial stenosis <50%, 50%-74%, 75%-99%, occlusion was 76.30% and 76.80%, 89.70% and 90.40%, 96.30% and 97.10%, 100% and 100%, respectively. Conclusion The influence factors of CTA of renal artery are the delayed time set, rotation time, the units dose of contrast medium and the speed of injection, breath-holding, the patients age and vascular calcification. CTA of renal artery can meet the clinical requirements in assessing the renal arterial stenosis.

Objective To observe CT features of struma ovarii (SO) in comparison of pathologic findings. Methods CT features of 9 patients with pathologically confirmed SO were analyzed retrospectively and compared with pathological findings. Results All tumors were unilateral and had smooth margins, 3 were cystic and 6 were cystic-solid lesions, 5 were high attenuation lesions in the cyst portion of the mass on contrast CT. The cyst wall moderately (n=3) or markedly (n=5) enhanced after administration of contrast medium. Scattered, stripe-like or ring-like calcifications were found in 6 patients. On pathology, most of cystic portions were filled with high proteinaceous gelatinous fluid of eosinophiclic colloid, and the solid portion of tumors consisted of the thyroid tissue and stoma containing abundant blood vessels and fibrous tissue. Conclusion SO appears as a smooth marginated multicystic mass with calcification, high attenuation lesionin plain CT, and marked solid part enhancement on contrast CT.

Objective To investigate the effect of tube voltage and iodine concentration of contrast medium (CM) on abdominal dynamic enhanced CT image quality.Methods Six miniature pigs underwent repeated upper abdomen dynamic contrast-enhanced CT scans in 4 scanning protocols with different concentration of CM and tube voltage,namely,protocol 1,CM with iodine concentration of 270 milligrams iodine per milliliter (mg/ml) and 80 kV tube voltage;protocol 2,270 mg/ml and 120 kV;protocol 3,370 mg/ml and 80 kV and protocol 4,370 mg/ml and 120 kV.The same iodine dose (600 mg/ml) and iodine delivery rate (IDR) (920 mg/s) were used in all protocols.The CM with iodine concentration of 270 mg/ml were injected at a flow rate of 3.4 ml/s,and 370 mg/ml CM injected at 2.5 ml/s.Image reconstruction was performed with iterative reconstruction (iDose4) in protocol 1 and 3,filtered back projection (FBP) was used in protocol 2 and 4.A subjective scoring system for image quality,image noise and sharpness was conducted by 2 radiologists independently.The measured values (peak of enhanced CT values,image noise of aorta,inferior vena cava,portal vein,hepatic vein and liver parenchyma) as well as the calculated values [their time-to-peak,signal-to-noise (SNR) and contrast-to-noise (CNR) ratios] were compared between among 4 protocols.The CT volume dose index (CDTIvol) and dose length product (DLP) were recorded from the CT console after each scanning.Factorial designed ANOVA was used for comparison of enhanced CT values of vessels and liver parenchyma,noise,SNR and CNR.The Kruskal-Wallis test was used for comparison of values among the 4 protocols,including the time-to-peak enhancement of vessels and liver parenchyma,the subjective scores of image quality indices.Result There was no significant differences in subjective scores of the image quality,image noise and image sharpness (P＞0.05).The scored were more than 3,and the images with 4 scanning protocols were all acceptable for diagnosis.There was no significant differences between protocol 1 and 3,protocol 2 and 4 in the peak enhancement CT values of aorta [(729±46) HU vs.(707±59)HU,(515±84)HU vs.(513±53)HU],inferior vena cava [(366±95)HU vs.(368±92)HU,(282±39)HU vs.(262 ± 67)HU],portal vein [(213± 18)HU vs.(201 ±29)HU,(180±21)HU vs.(176±27)HU],hepatic vein [(207±18)HU vs.(193±10)HU,(179±24)HU vs.(170±14)HU] and liver parenchyma [(128±7) HU vs.(127±4) HU,(135±5)HU vs.(135±6)HU] (P＞0.05).But the CT values of vessels (aorta,inferior vena cava,portal vein and hepatic vein) in protocol 1 and 3 were significantly higher than those in protocol 2 and 4 (P＜0.05),the CT values of liver parenchyma in protocol 1 and 3 were significantly lower than values in protocol 2 and 4 (P＜0.05).The image noises of vessels were higher in protocol 1 and 3 than noises in other protocols (P＜0.05),but there was no significant difference in liver parenchyma noise among protocols (P＞0.05).No significant differences were observed on the peak times,SNR and CNR in aorta,inferior vena cava,portal vein,hepatic vein and liver parenchyma among 4 protocols (P＞0.05).The CDTIvol and DLP were 199.67 mGy,1 597.4 mGy· cm respectively in protocol 1 and 3,585.12 mGy and 4 680.9 mGy· cm in protocol 2 and 4 (scanning with 120 kV).Conclusions CM with different iodinated concentration could achieve the same enhancement in the abdominal vessels and liver parenchyma by using the proper scan protocols,which have the same IDR and iodine dose per kilogram body weight.Higher vessel enhanced peak values were achieved when using the protocols with 80 kV tube voltage than 120 kV.By using a low dose protocol of 80 kV tube voltage with the iterative reconstruction algorithm,the quality of image can be warranted.

To provide the basis for preparation of diagnostic kits and vaccines in Toxoplasma gondii infection, the gene coding for the qualified recombinant p30 protein (SAG1) of this parasite was amplified by PCR, and the amplified gene was cloned into prokaryotic expression vector pET-30a(+) to construct the recombinant plasmid, and then transformed to E.coli DH5α. The positive recombinant plasmid was screened by PCR and double enzymes digestion, and the nucleotide sequence of p30 gene was determined by automated DNA sequencing. Meanwhile, the identified recombinant plasmid was transformed to E.coli BL21(DE3) with the expression of p30 on bacteria induced by IPTG and the expressed protein was identified by SDS-PAGE. The protein obtained was then further purified and refolded, and its biological activity was checked by Western blotting. It was shown that the size of the amplified gene was 750 bp with molecular weight of 30 ku, and this protein could specifically react with monoclonal antibody against p30 protein.
