The present study identified chemical constituents of Honghua Xiaoyao Tablet (HXT) and explored its biological connotation and characteristics on the premenstrual syndrome (PMS) treatment from the "disease-syndrome-symptom" association network. UHPLC-Q Exactive Orbitrap HRMS technology was applied to analyze the chemical constituents in HXT. According to the composition principles, the compatible herbs of HXT were divided into the Shugan Jieyu group, Huoxue Tiaojing group and Yiqi Jianpi group. The candidate targets of the corresponding prescriptions of HXT efficacy groups were collected from the Pharmmapper database and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0. The gene set related to the clinical symptoms included in Traditional Chinese and Western Medicine diagnosis and treatment standards were obtained from SoFDA, GeneCards, DisGeNET, MalaCards and literature published. The "HXT candidate targets-PMS (liver depression, Qi stagnation, and blood stasis syndrome) genes" network was constructed based on the gene interaction information, and further, the core network targets were screened out by topological characteristics of calculating network, and the functional exploration was carried out based on Kyoto Encyclopedia of Genes and Genomes (KEGG) for exploring the therapeutic advantages in PMS treatment of HXT efficacy groups, which were further verified experimentally

Succinic acid is regarded as C4 platform chemical, which has a huge potential market with wide applications in biopolymer, food, medicine, and so on. Production of succinic acid by microorganism fer-mentation has attracted much attention in recent times. By fermentation, succinic acid could be produced from renewable resources in place of petroleum with low cost and low pollution; especially CO2 could be fixed by microorganism to form the product, which is a promising way to deal with the green gas. Some E. coli have been chosen as good succinic acid producing strains because of their clear genetic backgrounds, convenience to be modified and controlled, and good growth properties with low nutrients requirements. The progress of genetic engineering strategy and metabolic engineering technology for construction of succinic aicd producing recombinant E. coli has been introduced in this paper with the discussion of the future re-search in this area.

Objective To explore the effect of iodine excess on bone metabolism in experimental autoimmune thyroiditis (EAT) rats. Methods We selected 36 female Lewis rats with body weight of (131 ± 15)g,and divided them into 3 groups randomly: control group, EAT group and EAT + high iodine group, assuring 12 rats in every group. These rats were fed fodder with different concentration of iodine(0.9,0.9, 18.0 mg/kg), and rats in EAT group and EAT + high iodine group were immunized with pig thyroglobulin(pTG) and complete Freund's adjuvant(CFA) to create EAT model. After two weeks, the pathological changes of the thyroid tissues were observed,and the serum thyroid autoantibody[thyroglobulin antibody(TGAb) and thyroid microsomal antibody(TMAb)], the thyroid hormone levels[triiodo thyronine(T3) and thyrine(T4)] and some relevant data of bone metabolism[bone gla protein (BGP), tartrate-resistant acid phosphatase (TRAP), C-terminal propeptide of type Ⅰ procollagen (PICP),C-terminal telopeptide of type Ⅰ collagen (ICTP), insulin-like growth factor- 1 ( IGF- 1 ), osteoprotegerin (OPG) and receptor activator of NF-κB ligand (RANKL)] were measured. Results Inflammatory cell infiltration and local follicular structural damage were observed in the thyroid tissues of EAT rats in EAT group and EAT + high iodine group, and the pathological changes of EAT + high iodine group were mainly thyroid follicular expansion and integration. The level of serum TGAb, TMAb, T3 and T4 of EAT rats in EAT group and EAT + high iodine group[ (63.01 ± 12.36)%, (60.62 ± 11.24)%, (3.78 ± 1.43), (125.12 ± 16.00)pmol/L and (75.00 ± 15.44)%,(72.15 ± 15.00)%, (3.69 ± 0.91 ), (149.40 ± 20.67)pmol/L] were higher than those of the control group[ (4.47 ±1.04)%, (5.73 ± 1.01 )%, (0.75 ± 0.12), (76.91 ± 9.30)pmol/L, all P < 0.05], and the level of serum TGAb,TMAb and T4 of EAT rats in EAT + high iodine group were higher than those of the EAT group(all P < 0.05).The level of serum BGP, PICP and IGF- 1 in EAT group[ ( 1.70 ± 0.31 ), ( 11.31 ± 1.52) μg/L, (0.31 ± 0.06 ) mg/L]were lower than those of the control group[ (8.60 ± 0.33), (14.28 ± 3.10)μg/L, (1.16 ± 0.02)mg/L, all P <0.05], and the level of serum TRAP, ICTP, OPG and RANKL[ ( 19.88 ± 3.60)ng/L, (2.43 ± 0.82), (22.36 ± 2.80),( 1.35 ± 0.23 )μg/L] were higher than those of the control group[ ( 14.57 ± 3.56)ng/L, (0.50 ± 0.20), (1.61 ± 0.34),(0.10 ± 0.02)μg/L, all P < 0.05]; compared with EAT group, the level of PCIP and OPG in EAT + high iodine group [ (8.03 ± 1.84), ( 16.80 ± 3.79)μg/L] were obviously decreased(all P < 0.05). Conclusions The reinforcement of differentiation and maturation of osteoblast in the EAT rats results in the increasing of bone resorption. The activity of osteoblast and osteoclast of the EAT rats are inhibited by excessive iodine, showing a low conversion-type osteoporosis.

Objective To investigate the application effect of interventional surgery in the treatment of facial superficial mixed hemangi-oma through the laryngeal mask ventilation under desflurane anesthesia. Methods In the period from February 2016 to April 2017 in our hospital 118 cases of facial superficial hemangioma under interventional surgery in infants( aged 3-15 months) were retrospectively analyzed;according to the difference of anesthesia,they were divided into control group (51 cases) and observation group (67 cases);the two groups of children were administered sufentanil anesthesia, in the control group laryngeal mask airway under propofol, the observation group was giv-en under laryngeal mask airway inhalation of desflurane maintenance. Then was compared the difference in anesthesia monitoring indexes of the two groups, such as mean arterial pressure ( MAP) , saturation of pulse oximetry ( SpO2 ) , heart rate ( HR) , end-tidal carbon dioxide ( ETCO2 ) , laryngeal mask removal time, loss of consciousness time, laryngeal mask removal time, consciousness recovery duration, clinical efficacy and intraoperative and postoperative adverse reactions difference. Results For the control group, the laryngeal mask removal time and consciousness recovery time length were significantly longer than those of the observation group and the difference was statistically signifi-cant (P<0. 05);after anesthesia induction, the laryngeal mask insertion time, operation start time and laryngeal mask removal time, MAP and HR of the observation group and the control group were lower than those before anesthesia induction, and MAP and HR of control group were lower than those of the observation group and the deference was statistically significant (P<0. 05). The total efficiency of the observa-tion group (97. 02%) was significantly higher than the control group (88. 24%), the adverse reaction rate (23. 52%) of children in the control group was significantly higher than that (7. 46%) of those in the observation group, and the differences were statistically significant (P<0. 05). Conclusion In the infant facial superficial hemangioma interventional surgery, laryngeal mask airway can be used for anesthe-sia maintenance for desflurane effect and clinical curative effect in the effective protection of anesthesia at the same time, but also can reduce the risk of anesthesia and intraoperative blood pressure fluctuations, especially in the stabilization of hemodynamics of the patients.

OBJECTIVEWe have identified a SNP within the seed-binding region for miR-502 in the 3'-UTR of the SET8 gene that codes for a methyltransferase for histone H4. SET8 methylates TP53 and thus regulates cell proliferation and genome stability. This study is to investigate the role for this SNP and its interaction with the TP53 codon 72 SNP in the age of onset of breast cancer.
METHODSWe conducted a case-only study of 1, 110 breast cancer cases. PCR-RFLP was used for SNP genotyping. Ages of onset of breast cancer among different genotypes were analyzed using SAS software.
RESULTSOur analysis revealed that the SET8 CC and TP53 GG genotypes were independently associated with earlier age of onset of breast cancer in an allele-dose dependent manner. Moreover, individuals with both SET8 CC and p53 GG genotypes developed cancer at age of 47.74 years, compared with 54.55 years for individuals with both SET8 TT and TP53 CC genotypes.
CONCLUSIONSmiR-502-binding SNP in SET8 may modulate SET8 expression and contribute to early development of breast cancer either independently or together with the TP53 codon 72 SNP.

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.

OBJECTIVETo investigate the effects of ox-LDL, ACEI and ARB on expressions and activities of TF and TFPI in VSMC.
METHODS(1) Rabbit VSMC was cultured by explant-attached method in vitro. (2) The effects of ox-LDL and valsartan on TF and TFPI expressions were analyzed by immunohistochemistry and immunofluorescence. Laser scanning confocal microscopy were applied to analyze the effects of ox-LDL and valsartan on TF expression. The effects of ox-LDL, valsartan and captopril on TF and TFPI antigen expressions were analyzed by ELISA. Chromogenic substrate method was used to determine the effects of ox-LDL, valsartan and captopril on TF activity. The effects of ox-LDL and valsartan on TF mRNA expression were analyzed by RT-PCR.
RESULTS(1) ox-LDL could upregulate TF antigen, activity and TF expression at mRNA level and downregulate TFPI antigen. (2) Valsartan and captopril could reduce TF antigen and activity in VSMC treated by ox-LDL, and valsartan reduce it in a dose-dependent manner. Valsartan could also attenuate TF expression at mRNA level in VSMC treated by ox-LDL. (3) Using ELISA, valsartan and captopril could also enhance TFPI antigen in VSMC treated by ox-LDL.
CONCLUSIONOur study showed upregulated TF and downregulated TFPI expression and activity by ox-LDL and these effects could be reversed by ACEI and ARB indicating a new insight on the antiatherosclerotic effects of ACEI and ARB.
