The total improvement rate of menstrual in three groups were 71.42% ,75.00% ,92.86% respectively. Conclusion Jiangzhipailuan decoction played a prominent role in regulating PPARα,PGC-1α and SREBP-1c,SCAP related to lipid metabolism in the treatment of polycystic ovarian syndrome.

Objective To explore the correlation of lung function and IFN-γ and IL-4 levels in peripheral blood in pulmonary tuberculosis patients. Methods The IFN-γ and IL-4 levels in peripheral blood of 75 pulmonary tuberculosis patients(severe 25 cases,moderate 25 casea,and mild 25 cases) and 30 healthy volunteers were measured by ELISA. Meanwhile FEV1 ,FEV1% and MMEF% of lung function in 75 pulmonary tuberculosis patients were measured.Results The levels of IFN-γ[(0. 204 ±0. 018) μg/L] and IL-4[(0. 523 ±0. 035) μg/L] in peripheral blood were significantly different both between tuberculosis group and control group and among tuberculosis patients ( severe,moderate,and mild) (t =7. 685,6. 374 ,all P ＜0. 05) ;FEV1 ,FEV1% ,and MMEF% of severe and moderate tuberculosis patients were significantly lower than those of mild tuberculosis patients and normal reference value; In tuberculosis patients, FEV1% and MMEF% were negatively related with IL-4 level in peripheral blood( r = -0. 46, -0. 43, all P ＜ 0. 05 ), also significantly positively related with the IFN-γ level in peripheral blood ( r = 0. 47,0. 45, all P ＜0. 05). Conclusion Pulmonary tuberculosis morbility may be due to cellular levels of patients. The IFN-γ and IL-4 levels in peripheral blood could affect the lung function of pulmonary tuberculosis patients.

Objective To evaluate the diagnostic efficiency of Q?SPECT, CTPA, Q?SPECT/CT, and Q?SPECT/CTPA for pulmonary embolism (PE) in rabbit models. Methods (1) The PE models were constructed by injecting Gelfoam into the femoral vein of New Zealand rabbits ( n=30) . Q?SPECT, CTPA, Q?SPECT/CT and Q?SPECT/CTPA fusion images were obtained by integrated SPECT/CT. (2) All images were interpreted by two experienced nuclear radiologists who were blind to pathologic findings. The locations and numbers of lung lobes with PE were recorded respectively. ( 3) Serial sectioning of the lungs was per?formed and pathologically determined. (4) Se, Sp and Ac of different methods were compared using McNemar test;PPV and NPV were compared usingχ2 test. Kappa test was used to analyze the consistency between two nuclear radiologists. Kappa values<0.40 were interpreted as poor consistency, 0.40 to 0.75 as moderate con?sistency, >0.75 as good consistency. Results (1) Histologically confirmed emboli were present in a total of 26 pulmonary lobes and absent in 79 lobes. (2)The Se, Sp, Ac, PPV, and NPV of 4 imaging methods were:53.8%(14/26), 93.7%(74/79), 83.8%(88/105), 14/19, 86.0%(74/86) for Q?SPECT;73.1%(19/26), 96.2%(76/79), 90.5%(95/105), 86.4%(19/22), 91.6%(76/83) for CTPA;76.9%(20/26), 93.7%(74/79), 89.5%(94/105), 80.0%(20/25), 92.5%(74/80)for Q?SPECT/CT;88.5%(23/26), 91.1%(72/79), 90.5%(95/105), 76.7%(23/30), 96.0%(72/75) for Q?SPECT/CTPA. (3) McNemar test showed Q?SPECT/CT and Q?SPECT/CTPA had higher diagnostic Se for the detection of PE than Q?SPECT (χ2=4.167, 7.111, both P<0.05) , but without any significant difference with CTPA in diagnostic efficiency (χ2=0-2.250, all P>0.05) . Q?SPECT/CT had higher diagnostic Ac than Q?SPECT (χ2=4.167, P<0.05) . There was no significant difference between Q?SPECT/CT and Q?SPECT/CTPA in diagnostic effi?ciency (χ2=0.001-1.333, all P>0.05). (4)Kappa values of 4 imaging methods for radiologist 1 and 2 were 0.902, 0.915, 0.973, and 0.884. Conclusions Q?SPECT/CT imaging provides good Se and Sp. The diag?nostic efficiency of Q?SPECT/CT is better than that of Q?SPECT and is corresponded roughly to the efficien?cy of CTPA, Q?SPECT/CTPA. The diagnosis of two radiologists on Q?SPECT/CT images has the best con?sistency.

Objective To investigate the image quality and radiation dose of 640-slice CT coronary arteriography(CTCA) with adaptive iterative dose reduction three-dimensional (AIDR3D)reconstrucction algoritym.Methods 640-slice CTCA with auto-matic exposure was performed on 84 consecutive patients.The original image data were reconstructed with AIDR3D and the filtered back-projection (FBP)algorithms at the image postprocessing workstation.Two experienced radiologists without knowing clinical information and reconstruction algorithms independently measured and calculated the image noise,signal-to-noise ratio and contrast-to-noise ratio with AIDR3D and FBP reconstruction algorithms.The qualitative image quality was assessed by using the 4-point scale.The radiation dose was calculated based on dose-length product exported on CT scanner.The quantitative and qualitative im-age quality with two kinds of reconstruction algorithm was analyzed statistically.Results The CTCA image noise was (27.20± 4.40)HU with AIDR3D and (60.00±12.40)HU with FBP,which with AIDR3D was decreased by 46.10% than that with FBP;the signal-to-noise ratio was 21.10 ± 5.10 with AIDR3D and 11.40 ± 2.80 with FBP,which with AIDR3D was increased by 84.70% than that with FBP;the contrast-to-noise ratio was 24.70±5.10 with AIDR3D and 13.50±3.20 with FBP,which with AIDR3D was raised by 82.20% than that with FBP,the differences in 3 indexes between the two kinds of reconstruction algorithm were statistically significant(P < 0.05 ).The CTCA qualitative image quality scores of proximal,middle and distal parts with AIDR3D were (3.90±0.30),(3.70±0.50)and (3.60±0.60)respectively,which all were higher than (2.60±0.60),(2.30± 0.60)and (2.10±0.70)with FBP respectively,the differences in 3 items between 2 kinds of algorithm had statistical significance (P <0.05).The total segments which could be used to diagnose the CTCA images with AIDR3D and FBP algorithms were 1 216 segments (96.50%)and 504 segments (40.00%),respectively,the difference had statistical significance(P <0.05).The mean ef-fective radiation dose was (2.10±1.00)mSv.Conclusion 640-slice CTCA with AIDR3D reconstruction algorithm not only signifi-cantly reduces the image noise than the conventional FBP algorithm,improves the quantitative and qualitative image quality,but also decreases the effective radiation dose.

Objective To compare the clinical effect of preserving the ascending uterine artery in laparoscopic hysterectomy with traditional laparoscopic hysterectomy.Methods 112 patients with various kinds of uterine benign lesions performed by hysterectomy were randomly divided into the preserving the ascending uterine artery in laparoscopic hysterectomy group(observation group,n =60) and traditional laparoscopic hysterectomy group (control group,n =52),The operation time,the intra operative blood loss,the postoperative complications rate and the perimenopausal symptoms in two groups were compared as well as the levels of blood calcium and the levels of hormone before operation,the first month,the sixth month,the first year,and the third year after operation.Results The opreration time [(95.5 ± 22.8) win] and intraoperative blood soss [(81.3 ± 11.6) ml] of the observation group was more than those of the control group [(68.8 ± 7.2) ml] (t =3.772,4.418,all P ＜ 0.05).The postoperative abnormal uniation and defection (1.7％) and fever incidence (1.7％) of the observation group was lower than those of the control group (11.5 ％,13.5 ％) (x2 =4.623,5.843,all P ＜ 0.05).The estradiol level of the observation group began to fall in 6 months postoperative,and had significant differences compare with those of the control group 6 months,1 year,3 years after operation [(328.4 ± 13.4) pmol/L vs (304.8 ± 15.2) pmol/L,(311.3 ± 12.9) pmol/L vs (248.5 ±13.6)pmol/L,(258.3 ± 11.4)pmol/L vs (138.7 ± 12.7)pmol/L] (t =8.758,25.121,52.688,all P ＜0.05).There was significant difference in the level of follicle stimulating hormone (FSH) and luteinizing hormone (LH) between the two groups 1,3 years after operation(t =-90.540,-123.229,-14.757,-19.845,all P ＜ 0.01).There was significant difference in the level of calcium between the two groups 1,3 years after operation(t =3.261,3.050,all P ＜0.05).The perimenopausal symptoms of the observation group was less than those of the control group(x2 =6.142,3.471,4.976,6.646,4.633,all P ＜ 0.05).Conclusion Laparoscopic hysterectomy of preserving the ascending uterine artery is safe and reliable;the recently ovarian function of the patients with hysterectomy is to maximize the preservation in the treatment,the women's quality of life will be to improved.

Objective To study the compliance of examinees,and effectiveness of colorectal distension with partially automated and individualized insufflation of air for dual-energy CT colonography.Methods Forty-six healthy adult volunteers without history of conditions affecting gastrointestinal motor function were enrolled in this study.One day before CT examination,volunteers were asked to orally administered 60 mL 4% diatrizoate meglumine five times for fecal tagging.Air was insufflated by using an inflator in a partially automated and individualized manner.The volunteers were initially asked to assume the right lateral decubitus position,then slowly turn to the supine position.Insufflation rate began at 1.5 L/min,and decreased to 0.5 L/min at later stage.The necessity and volume of air insufflation were decided according to effectiveness of colorectal distension on CT scout images,self-reported sensation of volunteers,and intestinal pressure.Dual-energy CT scanning was performed,and dual-energy blended images were acquired.Compliance of volunteers was statistically analyzed.The effectiveness of colorectal segments distension was statistically analyzed by using Kruskal-Wallis H test.Results No abdominal pain,bloating,nausea or vomiting were noted in the 46 volunteers.All volunteers easily accepted colorectal insufflation of air,with grade 1 compliance.The effectiveness of colorectal distension of grades 1,2,3 and 4 were 0%,2.1%,5.1% and 92.8%,respectively.The difference of effectiveness of colorectal segments distension had no statistical significance(χ2=6.19,P=0.288).The effectiveness of insufflation was poor in 6 colorectal segments,including 2 in sigmoid colon and 2 in rectum.Effectiveness of insufflation was suboptimal in 14 colorectal segments,including 4 in descending colon,4 in sigmoid colon,and 3 in rectum.Conclusion Compliance of examinees with partially automated and individualized insufflation of air for dual-energy CT colonography is excellent,with good effectiveness of colorectal distension.

Objective: To investigate the effect of comprehensive feeding intervention on feeding quality and weight gain of premature infants. Methods: Eighty-one premature infants admitted to the neonatal intensive care unit (NICU) of our hospital from September 2016 to December 2018 were selected and randomly divided into the intervention group (n=41) and the control group (n=40). Infants in the control group received routine nursing and infants in the intervention group were given comprehensive feeding intervention on the basis of routine nursing includingimproved Y type gastric tube, gravity tube feeding in prone position, oral movement intervention, colostrum oral immunotherapy and kangaroo nursing. The changes of feeding process were compared between the two groups and the occurrence of feeding intolerance in the two groups was observed. Results: The duration of tube feeding and hospital stay were lower in the intervention group than in the control group (P<0.05). No statistically significant difference was found in birth weight and body weight at discharge between the two groups (P>0.05), but the average daily weight growth rate [g/(kg·d) ] after 1 week and the milk volume [ml/(kg·d)] at 1 week were higher in the intervention group than in the control group(P<0.05). The incidence of gastric retention, abdominal distension and vomiting in the intervention group was lower than that in the control group, but only the difference in the incidence of gastric retention (24.4% vs 47.5%) was statistically significant (P<0.05). The incidence of feeding intolerance was significantly lower in the intervention group than in the control group (24.39% vs 47.50%, P<0.05). Conclusion Comprehensive nursing intervention can shorten the tube feeding time of premature infants, promote the weight growth of premature infants, improve the feeding quality, reduce the incidence of feeding intolerance, and reduce the hospital stay of premature infants, so as to reduce the hospitalization cost, improve the quality of life of premature infants, and increase the satisfaction of parents.

Purpose To analyze the gene subtypes and characteristics of human papilloma virus(HPV)infection among women attending outpatient and physical examination centers at our hospital.Methods We utilized Polymerase Chain Reaction(PCR)combined with reverse dot hybridization to detect 28 HPV gene subtypes.Results HPV infection rate among the women was 24.15％.The five most prevalent high-risk(HR)and low-risk(LR)HPV gene subtypes were HPV 52,16,53,58,39,and HPV 61,81,54,42,44,respectively.Single and double infections accounted for 68.97％and 20.72％,with no signifi-cant difference found in the combination of multiple infection types.When stratified by age,the highest HPV infection rate was found among the group aged ≤25 years,followed by the group aged ≥66 years and then the group aged 56-65 years.This pattern of HPV infection rates across age groups revealed an approximate U-shaped curve.Conclusion The majority of female HPV in-fections in Huadu district are single infections,primarily affecting young and middle-aged women.HPV gene subtypes exhibit the characteristics of population or region-specific distribution.The overall infection rate of HPV is 24.15％,with the most common types being 52,16,and 53.The three peak age groups for HPV infection ranges are ≤25 years,56-65 years,and ≥66 years.

Objective To systematically evaluate and analyze the evidence level of randomized controlled trials (RCT) of preoperative skin preparation for emergency percutaneous coronary intervention (PCI), and to understand the current research status and evidence level of preoperative skin preparation randomized controlled trials for emergency PCI, and provide reference for skin preparation for emergency PCI. Methods PubMed, EMbase, The Cochrane Library, CINAHL, JBI, CBM, CNKI, Wanfang DATA were searched by computer from inception to March, 2018 for emergency PCI preoperative skin preparation randomized controlled trials. Two evidence panel members searched and selected articles independently and the quality was assessed in accordance with Cochrane Manual. The articles were analyzed with Review Manager 5.3, and the evidence quality was assessed with GRADE profiler 3.6.1 software. Results A total of 5 RCTs were included, of which the number of RCTs with grade A quality was 1 and the number of RCTs with grade B was 4. The results of the Meta analysis showed that there was no significant difference in the incidence of skin infections at the postoperative puncture site by conventional methods for routine removal of surgical wild hair and no removal of hair prior to emergency PCI (P＜0.05). In addition, regular removal of hair before surgery may result in prolonged preoperative preparation and may cause psychological discomfort to the patient. After the GRADE system rating, the quality of the evidence body was of a lower level. Conclusions It is more beneficial to shorten the treatment time without routine removal of all the hair at the puncture site and the surrounding patients. The evidence included is not yet certain whether the incomplete removal of hair can reduce the infection rate. In the future, more large-scale, multi-center, high-quality research should be carried out to provide more credible evidence for this study.
