To clarify the active components in Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma, main components were gradually knocked out from the capsules, the effects of knockout capsules on uterine contraction, TNF-α secretion, murine splenocytes (SPL) and hysteromyoma cells proliferation were evaluated, respectively. The inhibition of capsules on uterine contraction was weakened by gradient knockout of paeoniflorin, paeonol, and amygdalin. The suppression of capsulte on TNF-α secretion was reduced by gradient knockout of gallic acid, cinnamaldehyde, pentagalloylglucose, and pachyman. The promotion of SPL cells proliferation was reversed by gradient knockout of gallic acid, paeoniflorin, cinnamaldehyde, quercetin, and pachyman. The depression of capsules on hysteromyoma cells proliferation was attenuated by gradient knockout of paeoniflorin, paeonol, pentagalloylglucose, and albiflorin. In conclusion, the compounds mentioned-above could be the key active basis of Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma.

OBJECTIVETo investigate the characteristics of microbial degradation of aniline by a stable bacterial consortium.

METHODSThe bacterial consortium was isolated from activated sludge treating chemical wastewater using aniline as the sole source of carbon and nitrogen by enrichment and isolation technique. The biomass was measured as optical density (OD) at 510 nm using a spectrophotometer. Aniline concentrations were determined by spectrophotometer. The intermediates of aniline degradation were identified by GC/MS method.

RESULTSThe bacterial consortium could grow at a range of aniline concentrations between 50 and 500 mg/L. The optimal pH and temperature for aniline degradation were determined to be 7.0 and 30, respectively. The presence of NH4NO3 as an additional nitrogen source (100-500 mg/L) had no adverse effect on bacterial growth and aniline degradation. The presence of heavy metal ions, such as Co2+, Zn2+, Ni2+, Mn2+ and Cu2+ had an inhibitory effect on aniline degradation.

CONCLUSIONSThe isolated bacterial consortium can degrade aniline up to 500 mg/L effectively and tolerate some heavy metal ions that commonly exist in chemical wastewater. It has a potential to be applied in the practical treatment of aniline-containing wastewater.

OBJECTIVETo investigate the effect of rat Schwann cell secretion on the proliferation and differentiation of human embryonic neural stem cells (NSCs).

METHODSThe samples were divided into three groups. In Group One, NSCs were cultured in DMED/F12 in which Schwann cells had grown for one day. In Group Two, NSCs and Schwann cells were co-cultured. In Group Three, NSCs were cultured in DMEM/F12. The morphology of NSCs was checked and beta-tubulin, GalC, hoechst 33342 and GFAP labellings were detected.

RESULTSIn Group One, all neural spheres were attached to the bottom and differentiated. The majority of them were beta-tubulin positive while a few of cells were GFAP or GalC positive. In Group Two, neural spheres remained undifferentiated and their proliferation was inhibited in places where Schwann cells were robust. In places where there were few Schwann cells, NSCs performed in a similar manner as in Group One. In Group Three, the cell growth state deteriorated day after day. On the 7th day, most NSCs died.

CONCLUSIONThe secretion of rat Schwann cells has a growth supportive and differentiation-inducing effect on human NSCs.

In 2012, the preparation process and quality standard for Guizhi Fuling capsule were improved. To compare the effects and differences of capsules before (2011) and after(2012-2014) the improvement, evaluation models for intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma were applied in rats. Models were induced by oxytocin, liqiud bacteria mixture and estrogen loading, respectively. The capsules (12 batchs/year, 48 bathcs in all), sampled randomly in 2011-2014, the effects were assessed using the three models. In anti-dysmenorrhea models, remarked reduction of writhing frequency, ET-1 and PGF2α content in uterus could be detected, as well as extension of writhing latency. In pelvic inflammation rats, depression of TNF-α and raise of IL-2 were induced by earh batch of capsules. In hysteromyoma model, uterine weight and smooth muscle proliferation, including E2 and P level in plasma, were lowered obviously by all batchs of capsules. Secondly, Guizhi Fuling capsules produced in 2012-2014 revealed better effectiveness than the ones manufactured in 2011. Moreover, pharmacodynamics indexes of the samples made in 2011 differed significantly between groups, which could not be observed in the ones ot 2012-2014. After tne preparation process and quality standard improvement, the effectiveness and homogeneity of Guizhi Fuling capsules were enhanced.

Objective Studies on cardia-cancer caused by hereditary factors. Methods Case-control method was adopted,with information including name,sex,date of birth,date of death of all the Ⅰ,Ⅱ,Ⅲ relatives of the patients,diagnosis and the treatment collected. The hereditary probability of cardia cancer and the separation degree were calculated by Falconer and Li-Mentel-Gart. Results (1) Prevalence rates of cardia-cancer on relative Ⅰ,relative Ⅱ,relative Ⅲ of cardia-cancer patients appeared to be 0.54%,0.04%,and 0.05% respectively. Prevalence rates of upper-digestive-tract-cancer of relative Ⅰ,relative Ⅱ,relative Ⅲ of cardia-cancer patients showed as: 2.50%,0.36% and 0.13% respectively. Data showed that relative Ⅰ> relative Ⅱ> relative Ⅲ and family cluster existed in both males and females. (2) Cardia-cancer hereditary probability of the relative Ⅰ cardia-cancer probands was 11.71%,with males as 14.01% and females as 14.72%. The upper-digestive-tract-cancer hereditary probability of the relative Ⅰ cardia-cancer probands was 13.87%,with males as 11.49% and females as 23.08%,both below 25%,indicating this was a low hereditary cancer. (3) The upper-digestive-tract-cancer separation of the blood compatriots of cardia-cancer patients was 0.0452,with males as 0.0441 and females as 0.0507,both below 0.25,indicating the nature of a multi-gene but not single-gene hereditary way. Conclusion Hereditary factor is recognized as one of the high risk cardia cancer,but not the most risky factor causing the high morbidity of cardia cancer in Shanxi province.

OBJECTIVETo investigate the potential effects on cognitive function, prognosis, and neuropeptide levels of patients in response to combination therapy with ornithine aspartate plus naloxone for hepatic encephalopathy.

METHODSEighty-four consecutive patients diagnosed with hepatic encephalopathy were randomly divided into two equal groups. The control group (n = 42) received traditional medical treatment, and the research group (n = 42) received the traditional medical treatment as well as the combination therapy with ornithine aspartate plus naloxone. The supplemental treatment was comprised of daily intravenous injection of 10-15 g ornithine aspartate in 250 ml of 5% glucose plus intravenous drip of 3 mg naloxone in 100 ml of 5% glucose, and was given in 7-day cycles for one or two cycles. The cognitive function of patients was assessed by Hasegawa Intelligence Scale (HDS) and Mini-Mental State Examination (MMSE) questionnaires. The effective rate and time duration from coma to consciousness were recorded. Changes in blood ammonia level, markers of liver function, and neuropeptide levels were measured by standard biochemical assays. Intergroup differences were assessed by the Chi-squared test.

RESULTSThe HDS and MMSE scores of the research group were significantly higher than those of the control group after therapy. The effective rate, time duration from coma to consciousness, blood ammonia, the liver function markers alanine aminotransferase, gamma-glutamyl-transpeptidase and total bilirubin, and the neuropeptides arginine vasopressin and beta-endorphin were remarkably improved after treatment in the research group, as compared with that in the control group.

CONCLUSIONSupplementing the traditional treatment for hepatic encephalopathy with ornithine aspartate plus naloxone combination therapy provides better therapeutic outcome than traditional treatment alone.
