Serum E2 increased (P<0.01), while LH, T and LH/FSH decreased in two groups (P<0.01). After treatment and withdrawal treatment for 3 months, improvement of clinical symptoms and sex hormone levels in CWM group was superior to CM group (P<0.01), FPG, FINS, TG, TC and BMI of CWM group decreased in CWM group (P<0.05), and lower than that of CM group (P<0.05,P<0.01). Adverse reaction rates of WM group and CWM group were 17.1% and 5.71% (P<0.05).Conclusion Efficacy of TCM periodic therapy combined with Diane-35 in treatment of PCOS is significant, which can obviously improve patients’ clinical symptoms, and regulate hormone and lipid metabolism disorders, with fewer adverse reactions.

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.

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.

Objective To evaluate the usefulness of diffusion-weighted magnetic resonance imaging (DWI) and apparent diffusion coefficients (ADC) in differentiating tumor, edema, and normal brain tissue, and in classification of cerebral gliomas. Methods Using Philips Achieva 1.5T super conduct MR scanner, 46 patients with gliomas underwent conventional MR imaging and DWI. The ADC of regions of interest ( ROI ) were measured with two different b values, 0s/mm2 and 1000s/mm2. ROIs were manually placed over areas of tumor,edema, and normal brain tissue. Results The signals of DWI and ADC map in tumor tissue were respectively higher and lower than those in normal brain tissue. The ADC values in tumor were 1.68 ± 0.18,1.65 ± 0.20,1.29 ±0.16,1.21 ±0.21 for grade Ⅰ、Ⅱ、Ⅲ、Ⅳ gliomas, respectively; the corresponding figures in edema were 1.74 ±0.22,1.72 ±0.19,1.35 ±0.20,1.28 ±0.19, respective. The ADC values in tumor were not significantly different from the values in edema (P ＞0.05); however, both values were significantly different from those in normal brain ( P ＜0.05 ). The ADC value of low grade ( grade1-2 ) gliomas was significantly higher than that of high grade (grade3-4) glioma (P＜0.05). Conclusion ADC values can aid in distinguishing tumors from normal tissues, but can not distinguish tumors from adjacent edema. Individually, ADC values overlapped considerahly. ADC value is associated with cellularity of gliomas. DWI can help characterizing the malignancy of gliomas.

Objective To observe the clinical efficacy of cerebral palsy children with liver strong spleen weak syndrome treated with integrated traditional Chinese medicine therapy. Methods Eighty cerebral palsy children with liver strong spleen weak syndrome were divided into treatment group (40 cases) and control group (40 cases). Patients in control group were treated with conventional therapy (including exercise therapy, occupational therapy, guidance education, physical factors, and psychological therapy), and patients in treatment group were treated with integrated traditional Chinese medicine therapy (acupuncture and traditional Chinese medicine medicated bath) additionally. Three months were set for a course of treatment, and the whole treatment lasted for a total of four courses. TCM clinical symptoms were scored every six months, muscle tone (MAS), gross motor function (GMFM), and daily life activity ability (MBI) were evaluated every three months for both groups. Results There were significant differences in the total scores of TCM clinical symptom, MAS, GMFM, and MBI at different treatment time points in the two groups, compared with that before treatment (P<0.01). There were significant differences in the total scores of clinical symptom for Chinese medicine, MAS, GMFM, and MBI at different treatment time points for treatment group, compared with that of control group (P<0.05). Conclusion Integrated traditional Chinese medicine therapy (acupuncture and traditional Chinese medicine medicated bath) for cerebral palsy children on the basis of western medicine therapy can more effectively improve function and life quality of children patients.

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.
