Objective To preliminarily evaluate the efficacy and safety of chemotherapy on hemophagocytic lymphohistiocytosis(HLH) with hepatic dysfunction in children.Methods The children diagnosed as non-malignancy-associated HLH from Mar.2004 to Apr.2008 were selected,and the therapeutic effect was evaluated according to the HLH-04 protocol at the 8th week of chemotherapy,and the level of serum alanine aminotransferase(ALT),serum albumin(Alb) and plasma fibrinogen(Fib) were detected at pretherapy,2 weeks and 8 weeks of post-treatment.Results Altogether 60 HLH children complicated with hepatic dysfunction before chemotherapy,47 children had increased ALT,58 children had decreased Alb,and 38 children had decreased Fib.Forty-two cases(70%) were virus-associated HLH,1 case(1.7%) was fungi-associated HLH,and 17 cases(28.3%) had unknown origin.Among the 60 children,55 cases showed improvement in the 4 weeks of inductive treatment,15 cases gave up therapy,45 cases completed the 8 weeks of inductive treatment according to the protocol(among these children,42 cases had no active disease,3 cases had active disease),and these 45 children had obviously improved ALT,Alb and Fib at 2 weeks and 8 weeks of post-treatment,compared with pretherapy,the differences had statistical significance(Pa

Ralstonia metallidurans CH34 was isolated from the deposit of a znic factory .The degradation of phenol by R .metallidurans CH34 was investigated. The results showed that R . metallidurans CH34 possesses high ability to degrade phenol with the biodegradation rate constant of 0.33 . The optimal pH , temperature and volume of medium for phenol degradation are pH 7.0 , 30℃ , and 20%(v/v), respectively . In addition , this strain retains its ability to degrade phenol in the presence of high concentration of heavy metal ion .The sodium citrate , sodium succinate can enhance the degradation of phenol.

Objective　To investigate the prognostic influencing factors and recovery of CD4+ T lymphocytes in elderly HIV/AIDS patients after antiviral therapy by analyzing basic data and clinical follow-up data of elderly HIV/AIDS patients. Methods　The clinical data of 3 618 elderly AIDS patients aged ≥50 yeas who received antiretroviral therapy (ART) at HIV ART sites in Liuzhou City from 2005-2015 were collected. The data, including basic information, CD4+ T cell count, WHO clinical stage, infection route and follow-up, were retrospectively analyzed. Kaplan-Meier method was used to compare the differences in patient survival, multivariate Cox regression to analyze the independent influencing factors influencing the risk of death, and to compare the recovery of CD4+ T cell counts during follow-up of patients of different genders. Results　During the follow-up period, the 5-year cumulative survival rate up to the observation endpoint was 0.82 (female) and 0.66 (male). Multivariate logistic regression analysis showed that the risk factors affecting the effect of antiviral treatment were age (OR=1.909, 95%CI:1.474-2.464, P<0.001), body mass index (BMI) (OR=0.744, 95%CI: 0.574-0.965, P=0.026), opportunistic infections (OI) (OR=1.223, 95%CI:1.028-1.454, P=0.023), gender (OR=0.692, 95%CI:0.503-0.952, P=0.023) and baseline CD4+ T lymphocytes count (OR=0.563, 95%CI:0.429-0.739, P<0.001). Recovery of CD4+ T lymphocyte counts showed when baseline CD4+ T lymphocyte counts were less than 200 cells/mm3, older women with HIV/AIDS had higher CD4+ T lymphocytes than men at all times of ART treatment (P<0.05). Conclusions　Older women have a higher survival rate than older men after five years of antiviral therapy. Age, BMI, gender, OI and baseline CD4+T lymphocyte count may be important indicators that affect the survival of elderly HIV/AIDS patients. Older women showed better recovery of CD4+ T lymphocytes than older men during the 4-year follow-up period after ART.

Objective To explore the influence of using lidocaine in the second stage of labor among primiparas. Methods 300 primiparas were divided into three groups. When Group A has uterus contractions with anal fold releasing, bilateral pudendal nerve was conducted by block anesthesia with lidocaine hydrochloride. When Group B has the uterus contractions with head visible on vulva gapping 2～3 cm, lidocaine hydroctdoride bilateral pudendal nerve was carried out by block anesthesia. Group C was not carried out any measures. Results The shortest time of the second stage is Group A. Group C is the longest one. Pain in groups A, B significantly reduced than in group C. The condition of perineum in Group A and B were better than that of in Group C, the rate of postero-lateral episiotomy and the level of perineal laceration in Group C were higher. Conclusions Bilateral pudendal nerve block anesthesia can shorten the second stage of labor and suturing time, alleviate the pain of delivery, reduce the rate of postero-lateral episiotomy and the perineal laceration, and raise the rate of perineal integrity. Compared with the head visible on vulva gapping, dilatation of cervix 10 cm can get the better effect of shortening the second stage of labor.

AIMTo illustrate the non-equilibrium properties of drug permeation through stratum corneum (SC) to provide theory and method for transdermal drug delivery.

METHODSThe system of side-by-side permeation chambers in vitro was isolated, thus conditions for equilibrium state were decided. And a network thermodynamic model was established. Non-equilibrium and leakage experiments were completed with which tinidazole was pattern drug.

RESULTSThe properties of non-equilibrium including: long term to reach equilibrium state; delay-start of the permeation; uncertainty of initial drug permeable flux. The properties of leakage including: degression of drug permeable flux; changeability of permeation time constant.

CONCLUSIONThe permeation cell is believed to be a non-linear and time variable system.

OBJECTIVETo determine the effects of the autologous nucleus pulposus on the pain-related behaviors of hind paws in rats.

METHODSThe nucleus pulposus harvested from autologous coccygeal vertebra was applied beside the unilateral L4 and L5 nerve roots without compression. The mechanical withdrawal threshold of both paws were measured in different times after surgery. And hematoxylin and eosin (HE) staining was applied to observe the changes of nucleus pulposus and nerve roots.

RESULTSMechanical sensitivity of the operated side in paws obviously increased after application of autologous nucleus pulposus beside the lumbar nerve roots without compression. And HE staining showed obviously inflammatory changes in the nucleus pulposus and vacuolation in the nerve roots.

CONCLUSIONSInflammation resulted from nucleus pulposus may contribute to the development of mechanical hyperalgesia. The results suggest that in addition to mechanical compression, inflammation may be an important factor in the pathogenesis of sciatica.
