Toad venom is the Bufo bufo gargarizans or B. melanostictus after the ears of the gland secretion, used in the treatment of various cancers in recent years. Research shows that the main anti-tumor components in bufadienolide. Bufadienolide have free type structure and conjunct type structure. To identify and clarify the difference between bufogenin and bufotoxin contained in Bufonis Venenum, which was from B. bufo gargarizans, an UPLC-TQ-MS method has been established. UPLC-TQ-MS method was used to identify and quantify the major bufadienolides in Bufonis Venenum. UPLC-TQ-MS assay with positive ion mode was performed on a Waters ACQUITY UPLC BEH C, (2.1 mm x 100 mm, 1.7 µm) with the mobile phase consisting of 0. 1% aqueous formic and acidacetonitrile in gradient elution at a flow rate of 0.4 mL · min⁻¹ and the column temperature was set at 35 °C. By comparing their retention time and high resolution mass data of Bufonis Venenum extracts, 37 effective components were primarily identified by MS/MS analysis in positive ion mode. Twenty-six of them were free-type bufadienolides (bufogenin), 11 of them were conjugated bufadienolides. There were significant differences in the main composition between fresh and processed Bufonis Venenum. The study found that the chemical composition of toad venom through great changes after processing, conjunct type content is much less, free type content as well change.

To investigate the effects of carbamazepine (CBZ) on the plasma concentrations of valproic acid (VPA) and its toxic metabolite 2-propyl-4-pentenoic acid (4-ene VPA) in epileptic patients, the plasma concentrations of VPA and 4-ene VPA were determined, and the effect of CBZ on pharmacokinetics of VPA was evaluated. All patients had been divided into two groups (VPA group, n = 87; and VPA+CBZ group, n = 19). As compared to VPA group, the combination of CBZ significantly (P < 0.01) decreased the trough concentration of VPA [VPA group, (69.5 +/- 28.8) microg x mL(-1); VPA+CBZ group, (46.3 +/- 25.6) microg x mL(-1)] and does-adjusted VPA trough concentration [VPA group, (4.89 +/- 2.21) microg x mL(-1) x mg(-1) x kg(-1); VPA+CBZ group, (3.14 +/- 1.74) microg x mL(-1) x mg(-1) x kg(-1)]. However, the addition of CBZ did not influence the concentration of 4-ene VPA. The present study revealed that coadministration of CBZ can reduce VPA plasma concentration and may impact VPA clinical effect, therefore therapeutic drug mornitoring of VPA should be used when combined use of CBZ and VPA.

OBJECTIVETo culture the keratinocytes on the acellular pig dermis and establish a composite skin in vitro.

METHODSFull thickness skin taken from neonatal SD rats of approximate 24-hour-old was cultivated in asepsis condition, which was then separated into epidermal and dermal layers with low-temperature enzyme digestion. The basal lamina cells between the two layers were scraped off and the pure keratinocytes were obtained using gradient density centrifugation. In the experimental group, the keratinocytes were cultured on acellular xenodermis(AX) as the three-dimensional frames. In the control, the keratinocytes were cultured without any trophoblast. The air-liquid interface(ALI) culture continued after the primary culture. Routine histological HE staining and assay of Pancytokeratin and Laminin with strepavidin-biotin-peroxidase complex (SABC) method were used to study the morphology of CK and AX.

RESULTSHE staining demonstrated the formation of more than 4 lays of keratinocytes and basement membrane, with slight keratinization of the cells. Pancytokeratin(+) in immunohistochemical results confirmed that the cultured cells on AX were keratinocytes, not other kinds of cells. Laminin(+) indicated that new procreant basement membrane appeared in CK.

CONCLUSIONKeratinocytes cultured on the acellular pig dermis grow well and form basement membrane. This study implies successful construction of composite skin.

OBJECTIVETo investigate the postburn dynamic changes in the hypothalamus-pituitary-adrenal hormones in severely burned patients.

METHODSFifty burn patients were enrolled in the study. The plasma contents of total GC (cortisol), ACTH and aldosterone (ALDO) and urinary contents of 17-OHO and 17-KS were determined with radio-immunological assay (RIA) method after burn injury to compare with the normal values which were well established clinically.

RESULTSThe postburn plasma and urinary contents of the above indices were increased evidently with two peak values in shock and infectious stages, whilst the majority of he indices were lower than the normal values after 6 postburn weeks (PBWs). The values of these hormones were the lowest in dying patients. On the other hand, the values approached normal levels in those patients whose burn wounds were healing.

CONCLUSIONIncreases of the plasma and urinary levels of hypothalamus-pituitary -adrenal hormones in severely burned patients were constantly seen. Burn shock and infection seemed to be the two major factors in inducing postburn stress reaction in burn victims. Abrupt decrease of the hormone levels in plasma and or urine indicated adrenal failure predicting a poor prognosis of the burn patients.

OBJECTIVETo investigate the method and effect of axial pattern myocutaneous flap in reconstructing breast by using color doppler flow imaging (CDFI) technique.

METHODSSuitable axial myocutaneous flaps were selected according to the character of the focus in 26 cases of breast cancer after operation and radiotherapy. All the axial pattern myocutaneous flaps were designed on the basis of traditional design method before operation; then, CDFI with high resolution was used to examine the starting spot, exterior diameter, trail and length of the myocutaneous flaps' major artery. The myocutaneous flaps were redesigned according to the results of CDFI and transferred to reconstruct the breasts. The results of operation and examination were investigated.

RESULTSAccording to the CDFI, only one thoracodorsal artery's blood current was slow, its wall was rough and presented with arteriosclerosis. The blood flow was fluent and the vessel wall was smooth with other supplying arteries in the flaps. And no embolism, sclerosis or absence of blood vessel was found. The starting spots, exterior diameters, trails and anatomic layers of the major supplying arteries of the flaps were displayed clearly with CDFI, in accordance with the results of operation. Twenty-one cases of latissimus dorsi myocutaneous flap, 4 cases of the contralateral transverse abdominis myocutaneous flap and 1 cases of the bilateral transverse abdominis myocutaneous flap were used in this group. The flaps survived and healed well, the breasts were reconstructed well with perfect appearance, shape and sensation.

CONCLUSIONSCDFI is a simple, visualized and noninvasive method for designing the axial pattern myocutaneous flap in breast reconstruction, it can provide more scientific and accurate evidence for preoperative determination of myocutaneous flap transplantation.

OBJECTIVETo investigate the changes in the bacterial ecology and to analyze the bacterial resistance to antibiotics in a burn ward in Nanning district during the past 15 years, so as to provide reference to the clinical management of burn infection under subtropical climate.

METHODSFive thousand eight hundred and fifty-five strains of bacteria were isolated from the wounds and blood of 2269 burn patients admitted to our hospital from April of 1989 to March of 2004. Kiry-Bauer method was employed for the detection of antibiotic sensitivity test. The bacterial examination and bacterial resistance were analyzed in spans of every five years.

RESULTSBurn patients in our district were mainly infected by the gram negative bacilli (3559 strains, accounting for 60.79%), among which Pseudomonas aeruginosa, Enterobacter cloacae and Nitrate negative bacilli were major ones in every period. Gram positive cocci accounted for 33.99% (1990 strains), which ranked the second, among which Staphylococcus aureus, Staphylococcus epidermidis, and Coagulase negative staphylococci (MRCNS) were the most predominant ones. The bacterial resistance to multiple antibiotics, such as Gentamicin, third generation of Cephalosporin, and Norfloxacin showed a tendency of increase or maintained at high level while the incidence of resistance to Imipenem and Vancomycin was very low.

CONCLUSIONThe climate and the way of using antibiotics exerted direct effects on the status of the bacterial ecology and change in bacterial resistance to various antibiotics.

Objective To investigate and analyze the situation of urban and rural neglected children aged 3-6,in China,so as to provide basis for the analysis and comparison on relevant risk factors.Methods 1163 urban children aged 3-6 (with 49.6％ males and 4.5％ with minority ethnicity) were investigated from 25 cities of 14 provinces,autonomous regions and municipalities in the whole country.Multi-stage stratified cluster sampling method was used.Again,using the same sampling method,4096 rural children (of whom 50.6％ were males with 6.2％ as minorities) were chosen from 26 cities of 10 provinces or municipalities.Identification of children being neglected was based on “Child Neglect Evaluation Norms of Children Aged 3-6 Years in Urban/Rural China”.SPSS-Windows 13.0 was employed for data analysis.Scores,frequency/degrees,age,sex and types (physical,emotional,educational,safety,medical and social) of children under negligence on every group of the regions,were calculated.x2 test (Chi-Square) and Analysis of variance (ANOVA) were processed to determine the significance of their differences.Results The overall frequencies of negligence were 28.0％ and 53.7％ respectively among the urban and rural children aged 3-6,while the total degrees of negligence were 42.2 and 44.4 respectively.Significant difference was found between children from the urban and the rural areas (P＜0.05).Significant difference was also found between urban and rural children on every age group (P＜0.05).The frequencies of negligence among males were 32.6％ and 55.9％ respectively in urban and rural areas while among females,the figures appeared to be 23.7％ and 51.6％ respectively.The degrees of negligence were 42.7 and 44.6 among male while 41.8 and 44.3 among female children,in the urban or rural areas.Significant differences were found on male or female between urban and rural groups (P＜0.05).Frequencies of negligence in urban children aged 3-6 for the six types were from 5.1％ to 12.9％,with the frequency in rural areas as 13.1％-26.6％.Significant difference was found between urban and rural group for any other type (P＜0.05),in addition to the safety type.The degrees of negligence in urban children aged 3-6 for the different type were between 39.4 and 43.4,while in the rural areas as from 36.5 to 48.2,with significant difference for every type (P＜0.05).The degrees of negligence related to education,emotion,or physical strength were more serious on children from the urban than from the rural areas.The highest frequency of child negligence was seen in the single-parent families on both urban and rural groups (42.9％ and 60.0％ respectively),with no significant difference found (P＞0.05).The urban and rural children aged 3-6 were mainly involved in single item of negligence,with incidence rates as 16.5％ and 22.7％ and proportions as 58.9％ and 45.1％ respectively,despite the factors as age or sex.Conclusion There were large differences on the situation of negligence between the urban and rural children aged 3-6.The frequencies and degrees of negligence in every age group and different sex for children living in the rural areas were higher than those urban children.The frequency of negligence among boys was higher than girls for both urban and rural areas.The rural children had suffered more serious negligence than the urban children at any other type,in addition to the ‘ safety'.Both urban and rural children had the highest frequency of negligence in single-parent family,and were mainly suffered from single item of negligence.

Trichinosis is a global food-borne zoonotic parasitic disease caused by Trichinella spiralis(T.spiralis),which causes serious harm to animal production,and the public health safety of humans and animals.T.spiralis has a complex devel-opment history,and its entire life cycle is completed in the same host.To coexist with the host,it has evolved various immune escape mechanisms for avoiding immune clearance by the host,thus establishing long-term chronic infection.In this study,to aid in understanding the pathogenic mechanism of T.spiralis,the immune escape mechanism of Trichinella is discussed from three aspects:the molecular role of antigens in various stages,the immune regulatory effect on the host,and the formation of cysts to generate immune isolation.

OBJECTIVETo study the prevalence of asthma and its correlated factors in Zaozhuang area in 2003, to provide a basic consideration for prevention/treatment and control policy.

METHODS6 points were selected by stratified-clusterd-random sampling with a total of 16,725 persons expected, but only 10,610 subjects investigated.

RESULTSIn this survey, 128 asthma cases were identified with a overall prevalence of 1.21%. The prevalence for children was 2.02%, and for adult was 0.90% with the former significantly higher then the latter (chi(2) = 21.39, P < 0.01). Rates for male and female were 1.08%, 1.32% with a ratio of 1:1.22. For 77.97% of children with asthma. The initiative age of asthma was before 7 years old among children while among 36.23% of the adults, it was before 15 years of age. Correlation analysis showed that upper respiratory tract infection (OR = 17.81, 95% CI: 12.25-25.89), cold air exposure (OR = 3.43, 95% CI: 2.41-4.90), stimulation through cooking and by harmful gases (OR = 2.56, 95% CI: 1.80-3.63), allergic materials (OR = 2.74, 95% CI: 1.80-4.17) were main inducing factors. 65.63% of the asthma cases having had history of allergic disease while 25.78% having had family history with the OR of allergic history and family history as 21.69 vs. 73.96.

CONCLUSIONThe epidemic status of bronchial asthma was serious, with an assumption that asthma cases might have reached the number of 43 thousand in Zaozhuang area.
