Objective To observe the effect of Sopfrology-Lamaze childbirth breathing training on the delivery quality and negative mood of pregnant women.Methods 218 pregnant women were sampled and randomly divided into study group(A group,n =122) and control group(B group,n =96).A group learned the method and technique of Sopfrology-Lamaze childbirth breathing.From 28th week pregnancy to delivery,the times of training was more than 3 per week,and lasted 20 minutes.The rate of cesarean delivery,rate of severe pain,the time of labor,the amount of bleeding after 2h labor,and the dosage of patient controlled analgesia were observed.The selfrating anxiety scale (SAS) and self-rating depression scale(SDS) were used to assess the mood of prengnat women in 28th week pregnancy,before and after labor.Results There were significant difference in rate of cesarean delivery(A group 7.4％,B group 17.7％,x2 =5.46,P ＜ 0.01),rate of severe pain (A group18.8％,B group 59.4％,x2 =37.9,P ＜ 0.05),amount of bleeding after 2h labor (A group (219.43-± 31.47) ml,B group (287.5 ± 37.83)ml,t =14.50,P ＜ 0.05),and the dosage of patient controlled analgesia (A group(13.25 ± 1.89)ml,B group (19.87 ±2.52)ml,t=21.43,P＜0.05) between A group and B group.The SAS and SDS scores were lower in A group (SAS:before labor(44.3 ±7.6),after labor(42.2 ±4.7) ;SDS:before labor(45.2 ±4.7),after labor(42.2 ± 5.1),P ＜ 0.05) than those in B group (SAS:before labor(48.5 ± 6.6),after labor(47.35 ±5.1) ; SDS:before labor(47.7 ± 5.3),after labor (46.6 ± 6.3),P ＜ 0.05).Conclusion Sopfrology-Lamaze childbirth breathing training can improve the delivery quality and negative moods of pregnant women

BACKGROUND: Currently, a variety of new dressings have been on the market, which are diversified and exhibit multifunctional trends. However, ideal wound dressings are still in exploration.OBJECTIVE: To introduce the basic physiological function and polymer advantage of dextran as well as its effects to promote wound healing in combination with other macromolecule materials, in order to impel the development of dextran as a new medical dressing .METHODS: A computer-based search of CNKI, PubMed, WanFang, VIP databases was performed to retrieve reviews or research articles addressing dextran and medical dressings published from January 2000 to December 2016. The keywords were dressing, dextran, wound healing in Chinese and English, respectively.Finally, 31 articles were included in result analysis.RESULTS AND CONCLUSION: Dextran has the physiological functions of promoting wound healing and immune function. These physiological functions are the basis of dextran as a medical dressing. Additionally, dextran has some polymer advantages, such as water absorption, biodegradability and non-toxicity. It is noteworthy that dextran can be combined with macromolecules to produce new polymer materials that can promote wound healing in animal experiments. Taken together, dextran, as a medical dressing, has a broad clinical prospect in wound healing.

Thirty male weanling WAK strain rats were divided rondomly into 6 groups. All of the diets were pure synthetics according to AOAC. The 1st, 2nd and 3rd group were given diets containing 6, 15 and 24 ppm of zinc respectively, and 10% protein for all three groups, on the other hand, the 4th, 5th and 6th group were given diets containing 5% 10% and 20% of protein respectively, and 15 ppm of zinc.After feeding in stainless steel cage singly for 50 days rats were given intubately solution of 65Zn containing 1.5 ?Ci per 100g of body weight. Then the faeces and urine of rats were collected on 5 consecutive days, and the zinc absorption and retention of all of the tested rats were determined with method of 65Zn as tracer. The results indicated that. (1) The zinc absorption and retention of rats fed on the lowest zinc level were increased significantly. (2) The zinc absorption and retention of rats fed the lowest protein level were decreased significantly, and were improved clearly by increasing protein intake level. (3) The urine excretion of zinc is very low and can not be used as an index in zinc metabolism research. The methodology for determining zinc absorption and retention in organism with method of 65Zn and total zinc is discussed.

ObjectiveTo study the influence of anti-tuberculosis drugs on mitochondrial function in mice hepatocytes and to explore the mechanism of the anti-tuberculosis drugs induced liver injury.Methods A total of 150 mice were randomized into five groups:control group (C group),rifampin (RFP) group,isoniazid (INH) group,pyrazinamide (PZA) group and three antituberculosis drug combination group (MIX).The mice were administered intragastrically with 0.9 ％ NaC1 solution or RFP 135 mg · kg-1 · d-1 or INH 90 mg · kg-1 · d-1 or PZA 315 mg · kg-1 · d-1 or RFP+INH+ PZA (135±90+315) mg · kg-1 · d-1 once a day.Ten mice in each group were sacrificed at day 3,7 and 15 of administration,respectively.The following parameters in each group were monitored.the concentration of malondialdehyde (MDA),the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) in mitochondrion of hepatocytes and the concentration of 8-hydroxydeoxyguanosine (8-OH-dG) in mitochondrial DNA (mtDNA).The data were analyzed by one-way ANOVA or rank sum test.Results Along with the prolonged medication duration,the concentrations of MDA all gradually increased in RFP group (Z=6.020,P=0.049),IN H group (Z=10.220,P=0.006) and MIX group (Z=7.460,P=0.024),whereas the activity of SOD significantly decreased in RFP group (F=6.751,P =0.011 ) and MIX groups (F=4.891,P =0.041 ) compared with control group and PZA group.Meanwhile,the activity of GSH-PX was significantly lower in RFP group compared to the other groups (F=32.445,P＜0.01).The changes of other parameters didn't show meaningful trend.The concentrations of 8-OH-dG in mtDNA also increased in all treated groups,and those were all significantly increased in RPF group (F=6.602,P＜0.01 ),PZA group (F=5.927,P＜0.01) and MIX groups (F=7.974,P＜0.01).Conclusions Antituberculosis drugs can induce higher MDA concentration in mitochondrion and higher 8-OH-dG concentration in mtDNA,while result in lower activities of SOD and GSH-PX.The liver damage tends to become more severe along with the prolonged medication duration.The combination of three antituberculosis drugs could aggravate the damage of mitochondrion in mice hepatocytes.

Objective To analyze the outcome of patients receiving intrauterine insemination with husband sperm,in order to evaluate the effect of relative factors on pregnancy rate after intrauterine insemination. Methods Ninety-eight infertile couples who received intrauterine insemination in the Affiliated Hospital of Nantong University from March 2013 to May 2014 were selected as our subjects and 181 cycles were included. The information including clinical factors including maternal age,infertile time,infertile causes, ovulation induction protocol,time of insemination and postwash total motitle sperm(TMS)and pregnancy rate were recorded. Results (1)Totally 26 patients received clinical pregnancies,and clinical pregnancy rate(CPR) was 14. 36% per cycle. With age increase pregnancy rate decreased( χ2 = 1. 654 9,P = 0. 647).(2)The pregnancy rate of the patients was the same within the infertile time( χ2 = 1. 588 5,P = 0. 662).(3)The pregnancy rate of the patients with secondary infertility was lower than that of the patients with primary infertility,but there was no significant difference(χ2 = 0. 923 3,P = 0. 337).(4)The pregnancy rate of ovulation induction cycles was lower than that of nature cycles,but there was no significant difference(χ2 = 2. 222 0,P= 0. 136).(5)Postwash TMS was showed the same trend(χ2 = 0. 643 4,P = 0. 422). Conclusion In terms of intrauterine insemination with husband sperm,age,infertile time,infertile types,ovulation induction protocol and posrwash TMS can affect pregnancy rate,and the effects of various factors should be considered comprehensively in the process of therapy.

Objective To evaluate endoscopy for the diagnosis of primary gastrointestinal mucosaassociated lymphoid tissue lymphoma (MALT lymphoma) and diffuse large B-cell lymphoma (DLBCL).Methods The clinical pathology,hematological/biochemical studies,and endoscopic data of 98 primary gastrointestinal MALT lymphoma and DLBCL patients from Aug 2010 to May 2017 were analyzed retrospectively.Results 17 patients had higher than normal LDH blood level (＞270 U/L).47 patients were Helicobacter pylori (Hp) positive;Gastrointestinal endoscopic study,including endoscopic mucosal resection (EMR)/endoscopic submucosal dissection (ESD) and endoscopic ultrasonography established diagnosis of MALT lymphoma and DLBCL in 96 out of 98 cases (98％).The endoscopic manifestations of MALT lymphoma and DLBCL were ulcerative,uplift,diffuse and infiltrative,and erosive,with ulcerative type as the dominant one.The follow-up examination showed that the survival ratio (88％) of MALT patients was higher than that of DLBCL(68％),and more patients with lower Ann Arbor stage survived (92％) than those with higher Ann Arbor stage (64％).Conclusion Endoscopic biopsy together with endoscopic ultrasonography makes definite diagnosis of MALT and DLBCL.

Neutralizing antibodies are considered to be an important protective parameter used in HIV-l vaccine evaluation.However,the exact role that neutralizing antibodies plays in controlling the disease progression of HIV-1 infected peoples is still undetermined.In this paper,we compared the protective function of the neutralizing antibody response in the plasma from LTNP and TP against clade B and clade C pseudoviruses.No difference in the neutralizing activities between the plasma from LTNP and TP was found,which was consistent with the most recent reports.In addition,no correlations between the titer or breadth and CD4+ or viral load in HIV-1 infected individuals were found.The protective roles played by neutralizing antibodies in controlling disease progression of HIV-1 infected people need to be considered in a new viewpoint.

Objective To evaluate the antiretroviral therapy(ART),analyze the prevalence of resistance in rural areas,Henan,and explore the presence of minor resistant variants in pre-ART.Methods One hundred and forty-nine AIDS patients initiating ART were recruited and investigated at intervals of 6 months. Method of In-house developed by our laboratory for genotypjc resistance test was to analyze the occurrence of resistance among the failure of ART,and the allele-specific real.time PCR(ASPCR)was used to detect the minor resistant variants at the baseline samples once the resistance occurred.Results Vimlload significantly decreased among the patients who received ART(t=275,P=0.0001),but the absolute counts of CD4+T lymphocytes had no significant change(t=1.765 168,P=0.0852).Rate of resistance among the patients of treatment failure was 4.88%.The result of ASPCR in the survey of baseline showed that the minor resistant variants of M184V were detected in 7 patients and mutation K103N presented in 5 patients.Conclusion The primary drug-resistant straias in the untreated patients were found in Henan,and they might develop the dominant resistance strains and bring about the failure of ART.
