Objective:To study the curative efficacy of transabdominal ultrasound-guided Lauromacrogol combined with radiofrequency ablation in the treatment of fibroid and its effects on the serum estradiol (E2),luteinizing hormone (LH),follicle stimulating hormone (FSH) levels.Methods:90 patients of fibroid who were treated from June 2014 to June 2015 in our hospital were selected as the research objects.According to random number table,those patients were divided into the observation group (n=45) and the control group (n=45).Both groups were routinely examined before operation,the control group was treated with transabdominal ultrasound radiofrequency ablation,while the observation group was treated with transabdominal ultrasound-guided percutaneous radiofrequency ablation combined with radiofrequency ablation,Then visual analogue scale (VAS),menstrual volume,uterine fibroid volume,uterine volume,E2,LH,FSH levels,myoma symptoms and quality of life score,curative effect were compared between two groups.Results:After treatment,the total effective rate of observation group was significantly higher than that of the control group [95.55％(43/45)vs75.55％(34/45)] (P＜0.05);the VAS score,menstrual volume were significantly lower than those of the control group[(1.05± 0.23)score vs.(3.62± 0.50)score,(192.35± 22.10)mL 1 vs.(236.54± 24.57)mL](P＜0.05);The myoma volume,uterine volume were significantly lower than those of the control group[(32.13± 13.20)cm3 vs(40.81± 14.11)cm3,(101.93± 9.89)cm3 vs(118.36±11.20)cm3](p＜0.05);the serum E2,LH,FSH levels were significantly lower than those before treatment,but there was no difference between the two groups (P ＞0.05);the fibroid symptoms score was significantly lower than that of the control group [(4.50 ± 1.02)score vs.(10.34± 2.21)score] (P＜0.05),the quality of life score was significantly higher than that of the control group [(95.36± 14.29)score vs.(80.84 ±14.06)score] (P ＜ 0.05).Conclusion:Transabdominal ultrasound-guided lauromacrogol combined with radiofrequency ablation could enhance the efficacy of fibroid,which might be related to the decrease of serum levels of E2,LH,and FSH.

Objective To compare the clinical effect and safety evaluation of three different dose regimens for treating children with viral encephalitis.Methods Totally 126 cases treated in Xi'an Central Hospital from January 2010 to December 2015 were randomly divided into observation group 1 (ganciclovir combined with gangliosides,42 cases),observation group 2 (ganciclovir combined with gamma globulin,43 cases),and control group (39 cases).The clinical effect and levels of NSE,inflammatory cytokine were compared in the three groups.Results The total effective rate in observation group 1 was 95.24％ and that of observation group 2 was 93.02％,which were significantly higher than that of control group (79.48％).The disappearance time of headache,fever,convulsions,clouding of consciousness,meningeal irritation sign,cerebrospinal fluid abnormalities,and length of stay in observation groups (both 1 and 2)were significantly shorter than those in control group (P ＜ 0.05);After therapy,the levels of NSE in three groups were obviously decreased compared with those before therapy (P ＜ 0.05),and those in observation group were significantly lower than the control group (P ＜ 0.05);the levels of inflammatory cytokine in all three groups were obviously decreased compared with those before therapy (P ＜ 0.05),and that of observation group 1 had no statistical difference with the normal group,whereas that in control group was significantly higher than the normal group (P ＜ 0.05).Conclusion Ganciclovir combined with gangliosides as well as ganciclovir combined with gamma globulin were both effective methods in treating children with viral encephalitis and could decrease levels of inflammatory cytokine.Ganciclovir combined with gangliosides could effectively repair nerve damage,which deserves clinical expansion.

Objective To explore the association between folic acid supplementation during periconcerptional period and congenital heart disease in newborns to provide scientific evidence for making intervening measures.Methods Using stratified random cluster sampling,a total of 30 counties were sampled from Shaanxi Province.A questionnaire survey was conducted among childbearing-aged women pregnant between January 2010 and November 2013.All of the included women had definite pregnancy outcomes and had signed the consent form.Logistic regression was performed to investigate the association between folic acid supplementation during pregnancy and congenital heart disease in newborns.Results In total,28 354 questionnaires were available for analysis.The overall prevalence of congenital heart disease among live-birth neonates in the present study was 7.3‰.The percentage of childbearing-age women who had taken folic acid supplementation during pregnancy was 64.4％,while only 17.2％ of them took folic acid according to the specification.Taking folic acid regularly during pregnancy was associated with a lower risk of congenital heart disease among the newborns (OR 0.502,95％ CI:0.279 0.902).The multiple-factor analysis results also showed that taking folic acid regularly during periconcerptional period could reduce the risk of congenital heart disease (adjusted OR=0.512,P=0.046) when we controlled the family background factors,mother factors and exposure risk factors during pregnancy.However,no association was found between irregularly taking folic acid during periconcerptional period and the risk of congenital heart disease.Conclusion Taking folic acid according to the specification during periconcerptional period (taking folic acid during 3 months before pregnancy to 3 months after pregnancy with a daily dose of 0.4mg for more than 90 days) may prevent congenital heart disease of newborns.

Objective To analyze the effect of special risk exposures during periconception period on birth defects of newborns.Methods From Jul.to Dec.2013,the multi-stage stratified random sampling method was adopted.Women of childbearing age between 15 and 49 who were pregnant during 2010 to 2013 in Shaanxi Province were selected as study subjects for investigation on special risk factors exposed during periconception period.The Logistic regression model was adopted to analyze the association between newborns' birth defects and special risk exposures.Results The study included 30 010 women of childbearing age and 29 550 newborns with 572 (193.57/ 10 000) cases of birth defects.After adjusting for demographic factors,the risk factors for birth defects were drinking [OR=2.29,95％ CI (1.22,4.29)] and passive smoking [OR=1.25,95％ CI (1.02,1.53)] during periconception.There was a higher risk of birth defects when exposure to medicine [OR =1.64,95％ CI (1.04,2.61)],pesticides [OR =2.41,95％ CI (1.09,5.35)],biological risk factors [OR-1.64,95％ CI (1.05,2.56)],physical risk factors [OR=1.15,95％ CI (1.13,2.34)] and chemical risk factors [OR =2.36,95％ CI (1.36,4.11)] 3 months both before and after pregnancy.Similarly,after adjusting for demographic factors and behaviors,we found that birth defects were related to antibiotics,salicylates,and antitussive,which could increase the risk of birth defects (P＜0.05).Conclusion Exposure to passive smoking and drinking during periconception and exposure to medicines and pesticides,as well as biological,physical and chemical risk factors 3 months before and after pregnancy could increase the risk of birth defects in newborns.

Objective To explore the effect of Baihe Zhimu Tang(百合知母汤,BZT) on the airway inflammation in bronchial asthma rats.Methods Forty Wistar rats were randomized into control group,asthma model group,BZT group and dexamethasone (DX) group with 10 rats in each group.The bronchial asthma rat model was built by intraperitoneal injection of 10％ ovalbumin (OVA) and ultrasonic atomizing inhalation of 2％ OVA except for the control group.Thirty minutes before every ultrasonic atomizing inhalation,the BZT group was given BZT 3.68 g/(kg · d) by gastric perfusion;the DX group was administered DX injection 1.2 mg/(kg · d) by gastric perfusion;as for the control group and asthma model group,they were given normal saline of the same volume;all groups were intervened for 14 days.After that,HE staining was used to observe the pathological changes of lung tissue,the levels of interleukin-2 (IL-2) and interleukin-4 (IL-4) were measured,and the cell cycle and calcineurin (CaN) activity were observed in separated peripheral blood lymphocytes.Results For the asthma model group,there was a lot of inflammatory cell infiltration in the bronchial wall under light microscope,the content of IL-4 in the plasma was higher than that in the control group,while the content of IL-2 decreased,the proportion of G0/G1 phase lymphocytes decreased,the proportion of S phase and G2/M increased,and the CaN activity of lymphocytes increased significantly (P ＜ 0.05).For the BZT group,there was only a small amount of inflammatory cell infiltration in the lung tissue under light microscope,the IL-4 level in the plasma was lower than that in the asthma model group,while the IL-2 content increased,the proportion of G0/G1 phase lymphocytes increased,the proportion of S phase and G2/M decreased significantly,and the CaN activity of lymphocytes decreased significantly (P ＜ 0.05).Conclusion BZT could reduce lymphocyte proliferation,decrease IL-4 level and reduce airway inflammation by reducing CaN activity in peripheral blood lymphocytes of bronchial asthma rats.

Objective:To compare the clinical effect and safety of three different regimens treating children with severe pneumonia.Methods:120 cases treated in our hospital from January,2012 to January,2016 were randomly divided into the observation group 1 (dopamine combined with dobutamine,42 cases),observation group 2 (dopamine combined with phentolamine,40 cases),control group (38 cases).The clinical effect and levels of inflammatory cytokine were compared between the three groups.Results:The total effective rate in the observation group 1 was 90.48％ and that of observation group 2 was 87.5％,which were significantly higher than that of the control group (63.16％).The disappearance time of pulmonary rales,cough,dyspnea,pyretolysis and length of stay in the observation group (both 1,2) were significantly shorter than those of the control group (p ＜0.05).After therapy,the level of serum IL-6,IL-8,CRP and TNF-α in all the three groups were obviously decreased compared with those of before therapy (p＜0.05),and those of the observation group were significantly lower than the control group (p ＜ 0.05).Conclusion:Dopamine combined with dobutamine as well as dopamine combined with phentolamine were both effective methods in treating children with severe pneumonia,which were significantly better than conventional therapy.

Objective To investigate the sensitivity and variability factors that were assessed on the forced swimming test (FST) using BALB/C and Kunming mice. Methods The immobility time of FST was compared using Kunming and BALB/C mice in different experimental conditions including circadian rhythm ( day and night) ,gender and water temperature ( 12,22 and 32℃ ) . Results (①) The immobility time of BALB/C during the daytime( ( 142.42 ± 33.58) s) was significantly increased than that at night ( ( 104.89 ± 34.33 ) s). (② The immobility time of Kunming mice( (91.95 ± 40.32) s) was significantly decreased than that of BALB/C mice ( ( 142.42 ± 33.58 ) s). (③)The immobility time under the water temperature of 22 C ( ( 92.24 ± 25.81 ) s) was significant longer than that under the water temperature of 32C ( (60.72 ± 11.11 ) s). Conclusion BALB/C stain,male mice,daytime and water temperature of 22℃ should be chosen in the FST.

OBJECTIVETo observe amplitude changes of low frequency fluctuation in brain spontaneous nervous activities induced by needling at Hand Taiyin Lung Channel, and to preliminarily explore the possible brain function network of Hand Taiyin Lung Channel.

METHODSBy using functional magnetic resonance imaging (fMRI), 16 healthy volunteers underwent resting-state scanning (R1) and scanning with retained acupuncture at Hand Taiyin Lung Channel (acupuncture, AP). Data of fMRI collected were statistically calculated using amplitude of low frequency fluctuations (ALFF).

RESULTSUnder R1 significantly enhanced ALFF occurred in right precuneus, left inferior parietal lobule, bilateral superior temporal gyrus, bilateral middle frontal gyrus, left superior frontal gyrus, left inferior frontal gyrus, left medial frontal gyrus. Under AP significantly enhanced ALFF occurred in right precuneus, bilateral superior frontal gyrus, cerebellum, bilateral middle frontal gyrus, right medial frontal gyrus, and so on. Compared with R1, needing at Hand Taiyin Lung Channel could significantly enhance ALFF in right gyrus subcallosum and right inferior frontal gyrus. Significant decreased ALFF appeared in right postcentral gyrus, left precuneus, left superior temporal gyrus, left middle temporal gyrus, and so on.

CONCLUSIONNeeding at Hand Taiyin Lung Channel could significantly change fixed activities of cerebral cortex, especially in right subcallosal gyrus, right inferior frontal gyrus, and so on.

In the present experimental study, cecal ligation and puncture significantly increased the myocardial injury assessed in terms of excess release of creative kinase-MB (CK-MB), cardiac troponin I (cTnI), interleukin (IL)-6 and decrease of IL-10 in the blood following 12 h of laparotomy procedure as compared to normal control. Also, a significant increase in protein expression levels of high-mobility group box 1 (HMGB1) and decreased phosphorylation of glycogen synthase kinase-3β (GSK-3β) was observed in the myocardial tissue as compared to normal control. A single independent administration of telmisartan (2 and 4 mg/kg) and AR-A014418 (1 and 2 mg/kg) substantially reduced sepsis-induced myocardial injury in terms of decrease levels of CK-MB, cTnI and IL-6, HMGB1, GSK-3β and increase in IL-10 and p-GSK-3β in the blood in sepsis- subjected rats. The effects of telmisartan at dose 4 mg/kg and AR-A014418 at a dose of 2 mg/kg were significantly higher than the telmisartan at a dose of 2 mg/kg and AR-A014418 1 mg/kg respectively. Further, no significant effects on different parameters were observed in the sham control group in comparison to normal. Therefore it is plausible to suggest that sepsis may increase the levels of angiotensin II to trigger GSK-3β-dependent signaling to activate the HMGB1/receptors for advanced glycation end products, which may promote inflammation and myocardial injury in sepsis-subjected rats.
