Objective To observe the preemptive analgesia effects of katamine and elonidine, and to find out the influence of preemptive on stress responses. Methods 36 patients with hysteromyoma undergone hysteromyomec-tomy were randomly assigned to three groups (n = 12 each group) :group Ⅰ , control group, without preemptive analge-sia,the patients in control group were given continous epidural analgesia with 2% lidoeaine 12 - 14ml. Group Ⅱ ,the patients were injected 0. 6mg/kg katamine into epidural analgesia 30 minutes before operation. Group Ⅲ,the patients were injected 0. 6mg/kg katamine and 1.5μg/kg clonidine into epidural analgesia 30 minutes before operation. The patients in three groups were recorded VAS score on 2h ,4h ,6h, 12h ,24h after operation, also recorded the change of epinephrine(E) and norepinephrine(NE) and sensation and movement recovery time after operation. The side effects such as dizziness nausea,vomit,and exited talking were observed during the operation. Results The VAS score were significantly different between group Ⅰ ,Ⅱ and Ⅲ. The levels of E and NE in plasma in group Ⅰ were increased more than group Ⅱ and Ⅲ within 24 hours after operation, also there is significant difference in group Ⅱ compared with group Ⅲ in T1 ,T2 ,T3. The time of sensation and movement recovery were remarkably longer in group Ⅲ com-pared with group Ⅰ and Ⅱ, showing significant difference. There were no significant difference in side effects after operation in three groups. Conclusion The preemptive analgesia of kutamine and colnidine can relieve the pain of lower abdominal surgery and stress response after operation,and it do not increase the side effects.

C-reactive protein(CRP)is the most sensitive indicator of acute phase proteins.A growing body of evidence suggests that atherosclerosis,as a main cause of cerebral infarction,is a chronic inflammtory process.The present studies have found that the CRP levels and genetic polymorphisms are associated with atherosclerosis and cerebral infarction.As compared with coronary artery disease,the association between high-sensitive CRP and ischemic stroke is more closely.This article reviews the advaces in research on the biological characteristics of CRP,the factors influencing CRP levels,the CRP levels and the correlation between genetic polymorphisms and cerebral infarction.

Colorectal cancer(CRC)ranks the third in incidence and mortality rate among human tumors. Tumor relapse,me?tastasis and drug resistance remain the main obstacle to the success of CRC treatments. Compared to traditional chemotherapy ,target therapy seems to treat tumors in more precise and rational fashion with good response and often less toxic side-effect. Although target agents provide hope for more effective therapy,recent clinical studies have shown only modest benefit from target therapy similar to tra?ditional chemotherapy. Primary and secondary resistance to target agents is still observed and contributes to CRC treatment failure. The review summarizes research progress in the mechanism of drug resistance to target therapy in CRC treatment.

Objective To investigate the effect of dynamic regulation of negative pressure values in vacuum sealing drainage (VSD) on healing of soft tissue wounds.Methods From January 2013 to December 2015,115 patients were treated at our institute for open soft tissue defects of Gustilo-Anderson type ⅢaⅢc.They were 69 males and 46 females,aged from 17 to 76 years (average,44.7 years).They were divided into 4 groups to be subjected to different negative pressure values.Group A (n =29) was subjected to negative pressure values from-40 to-20 kPa,group B (n =29) to values from-80 to-60 kPa,group C (n =29) to values from-40 to-20 kPa for the first 72 hours followed by values from-80 to-60 kPa,and group D (n =28) to values from-60 to-80 kPa for the first 72 hours followed by values from-40 to -20 kPa.The 4 groups were compared in terms of drainage volume,wound shrinking,cleaning time,healing time and complications.Results The drainage volumes on the 7th day in groups B and D (4.89 ± 0.66 mL/cm2 and 4.33 ± 0.96 mL/cm2) were significantly higher than those in groups A and C (2.90 ± 0.67 mL/cm2 and 2.99 ±0.56 mL/cm2);the wound shrinking areas on the 14th day in groups B and D (14.16 ± 1.77 cm2 and 13.84 ± 1.65 cm2) were significantly larger than in groups A and C (12.57 ± 1.92 cm2 and 10.95 ± 1.37 cm2) (P ＜ 0.05).The cleaning time in group A was significantly longer than in the other 3 groups (P ＜ 0.05).The healing time in groups A and C was longer than in groups B and D (P ＜ 0.05).The incidences of pain in groups B and C were significantly higher than in groups A and D (P ＜ 0.05).The incidences of infection and blocking in group A were higher than in the other 3 groups (P ＜ 0.05).Conclusion Dynamic regulation of negative pressure values from-80 to-60 kPa for the first 72 hours followed by values from-40 to-20 kPa is an optimal choice for VSD management of soft tissue defects due to adequate drainage,obvious wound shrinking,quick cleaning and healing,and limited complications.

Objective To evaluate the association between isotretinoin pharmacokinetic parameters and CYP2B6 (cytochrome p-450) gene polymorphisms. Methods Blood samples were collected at different time points from 21 healthy male volunteers who received a single 40-rng oral dose of isotretinoin. High performance liquid chromatography-electrospray ionization mass spectrometry (LC-MS) was used for the quantification of isotretinoin in plasma samples which were standardized by dosage and body weight. PCR and restriction fragment length polymorphism (RFLP) analysis were performed to detect the G516T mutation in exon 4 as well as A785G mutation in exon 5 of CYP2B6 gene in these subjects. Results There was an obvious genetic linkage imbalance in exon 4 and 5 of CYP2B6 gene among these volunteers. In the case of CYP2B6*4 allele,3 (14.29%) people were CYP2B6*4/*4 homozygotes, 6 (28.57%) CYP2B6*1/*4 heterozygotes, and 12 (57.14%) CYP2B6*1/*1 wild-type homogygotes, while as far as CYP2B6*6 allele was concerned, 3 (14.29%)people were CYP2B6*6/*6 homozygotes, 5 (23.81%) CYP2B6*1/*6 heterozygotes, and 13 (61.90%)CYP2B6*1/*1 wild-type homozygotes. The reaction half-time (t1/2) and mean residence time (MRT) of isotretinoin were longer in volunteers carrying wild-type CYP2B6*4 allele than those of CYP2B6*4/*4 homozygotes (both P ＜ 0.05 ), while no significant difference was observed in maximum concentration (Cmax), peak time (Tmax) or area under the plasma concentration time (AUC) between the two groups of volunteers. There was no statistical difference in any of the above parameters between subjects carrying wild type CYP2B6*6 allele and those of CYP2B6 *6/*6 homozygotes (all P ＞ 0.05 ). Conclusions The mutation of CYP2B6*4 allele ia relevant to the metabolism of isotretinoin, which seems to be more rapid in CYP2B6*4/*4 homozygotes.

We detected the seroprevalence of Toxoplasma gondii (T.gondii) in the wild birds in northeast China.The wild bird's blood was collected from the cutaneous ulnar vein and the serum was isolated and used for detection of anti T.gondii antibody by modified agglutination test (MAT).Results showed that totally 179 birds' serum samples were collected.Twenty serum samples (11.17％) were positive with T.gondii antibody,which belonged to 9 orders,17 families and 31 species.The seroprevalence against T.gondii was about 5.26％ (1/19) in Columbiformes,9.09％ (9/99) in Passeriformes,14.29％ (3/21) in Falconiformes,15.00％ (5/22) in Piciformes,16.67％ (1/6) in Coraciiformes,and 25.00％ (1/4) in Anseriformes.Based on their feeding behavior,the seroprevalence was 12.00％ (3/25) in carnivorous wild birds,10.60％ (15/141) in omnivorous wild birds,and 15.38％ (2/13) in the wild birds feeding on aquatic animals or plants.These wild birds also can be sorted as migratory and sedentary (non-migratory) according to their migration habits,and the serum positivity was 11.67％ (14/120),and 10.71％ (6/59) respectively.The seroprevalence against Toxoplasma gondii in wild birds in northeast China is about 11.17％,which indicates a common infection of Toxoplasma gondii in wild birds.

Objective To understand and analyze the infection status of human parasites in Nanchang City, so as to offer a scientific basis for control of parasitic disease. Methods In 2014, a survey was performed according to the scheme of The 3rd National Survey of Principal Human Parasites. Intestinal parasites were surveyed among the residents in Jinxian County and Anyi County, Qingyunpu District and Qingshanhu District in Nanchang City, including the soil-transmitted nematodes (Ascaris lumbricoides, Trichuris trichiura and hookworm), Enterobius vermicularis, tapeworm and intestinal protozoa. Clonorchis sinensis was surveyed among the residents in Qingyunpu District and Qingshanhu District. Toxoplasma gondii was surveyed among the residents in two rural areas (Nanchang County and Xinjian County) and two urban areas (Donghu District and Xihu District). The ovums of the soil-transmitted nematodes, Clonorchis sinensis , tapeworm and other helminths were examined by the Kato-Katz, while Enterobius vermicularis among children was examined by cellophane anal swab, trophozoites and cysts of intestinal protozoa by saline smearing and iodine smearing , and IgG antibodies of Toxoplasma gondii by enzyme-linked immunosorbent assay (ELISA). Results Intestinal parasites were surveyed among 2424 residents in the whole city, in which 2414 residents were tested for the infection of soil-transmitted nematodes and tapeworm;1875 residents were tested for intestinal protozoa infection;74 children were tested for eggs of Enterobius vermicularis; 539 residents were tested for Clonorchis sinensis; and 2400 residents were tested for Toxoplasma gondii. Six kinds of intestinal parasites were found citywide, with a total infection rate of 9.49% (230/2424). The infection rate of soil-transmitted nematodes was 8 . 70% ( 210/2414 ) , in which the infection rate of Ascaris lumbricoides was 0.04% (1/2414), the rate of Trichuris trichiura was 0.91% (22/2414), and of hookworm was 7.83%(189/2414). The infection rate among 3 - 6 years old children of Enterobius vermicularis was 22.97% ( 17/74 ) . Tapeworm and Clonorchis sinensis were not found . The infection rate of intestinal protozoa was 0.21%(4/1875). The positive rate of Toxoplasma gondii's IgG antibody was 5.17% (124/2400). Conclusions In Nanchang City, the infection rate of soil-transmitted nematodes (Ascaris lumbricoides, Trichuris trichiura) and intestinal protozoa was lower. However, the infection rates of hookworm, Toxoplasma gondii and Enterobius vermicularis among 3 - 6 years old children are increasing in local areas. That should be the focus in prevention and control of parasitic disease in the future.

To construct an immortalized rat astrocyte strain genetically modified by rat preprogalanin gene (IAST/GAL) and detect its galanin (GAL) expression and secretion, a cDNA fragment of rat GAL in plasmid of pBS KS(+)-GAL was inserted into eukaryotic expression vector pcDNA3.1 (+) by DNA recombinant technology, then the restriction enzyme digestion and DNA sequencing were carried out to evaluate the recombinant. The pcDNA3.1 (+)-GAL and pcDNA3.1 (+) construct were transfected into immortalized rat astrocyte strain (IAST) by lipofectamine and the population of cells which stably integrated the construct was selected with 600 microg/mL G418. Individual clones were screened and expanded into clonal cell strains. Detection of Neo gene was used to validate the success of the transfection. Immunocytochemical staining, RT-PCR and radioimmunoassay were used to detect the expression and secretion level of GAL. The recombinant had been successfully constructed by restriction enzyme digestion and DNA sequencing. Detection of Neo gene showed that the pcDNA3.1 (+)-GAL and pcDNA3.1 (+) have been successfully transfected into IAST. After selection by using G418, IAST/GAL and IAST/Neo cell strains were obtained. IAST/GAL, IAST/Neo and IAST were immunostained positively for GAL, but the GAL average optical density of IAST/GAL was significantly higher than that of IAST/Neo and IAST (P< 0.01). The level of GAL mRNA expression and the supernatant concentration of GAL in cultured IAST/GAL were significantly higher than those of IAST and IAST/Neo (P<0.01), but no significant differences were found between the IAST and IAST/Neo (P>0.05). It was concluded that IAST/GAL strain was constructed successfully and it might provide a basis for the further study of pain therapy.
