A bacterium which can effectively degrade LAS (Linear Sodium Alkylbenzenesulfonate) was isolated from washing powder manufacturing effluent and was preliminarily identified as Corynebacterium jeikeium GZ6. The bacterium can degrade LAS up to till 700 mg/L, and the optimum pH, temperature and concentration of LAS are 7.0, 30℃ and 400 mg/L, respectively. The biodegradation rate can reach 98.7% after 24 hours'cultivation in the suitable conditions. Experiments also showed that some heavy metal ions such as Hg2+ , Co2+ , Cd2+ can differently inhibit the degradation of LAS.

Objective To study the expression and function relations of the p63 in ovarian serous carcinoma,and compare them with normal ovary tissue.Methods RT-PCR,in situ hybridization and im- munohistochemistry were used to detect the expression of the p63 in ovarian serous carcinoma,ovarian bor- derline serous tumors,ovarian benign serous tumors and normal ovary tissues.Results All samples ex- pressed p63 mRNA through RT-PCR and immunohistochemistry,while the levels of expression in ovarian tu- mors was higher than that of normal ovary.p63 in human borderline and malignant ovarian tumors was higher than that in human benign ovarian tumors with significant difference,which suggested p63 may play great roles in the origin and progression of ovarian tumors.The result of in situ hybridization showed that positive expression rate of p63 mRNA in ovarian cancer (92.1%) was significantly higher than that in normal ovary(0) or LWP ovarian cancer(50.0%).Conclusion Expression of p63 plays an important role in the development of varian carcinoma,and along with the difference of histological stage and clinico-pathological stage,the ex- pression of p63 gene and protein level were different.

OBJECTIVETo assess the efficacy of tendons of minimally invasive therapy (TMIT) combined drug therapy by comparing it with treatment by drug therapy alone on patients with knee osteoarthritis (KOA).

METHODSTotally 60 KOA patients were assigned to the treatment group and the control group according to random digit table, 30 in each group. Patients in the control group took Hydrochloric Acid Glucosamine Capsule and Celecoxib Capsule. Patients in the treatment group additionally received TMIT. The treatment course for all was 4 weeks. Scores for visual analogue scale (VAS) and the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index were observed and recorded at week 1 and 4 after treatment by acupotomology mirror.

RESULTSCompared with before treatment, improvement was shown in VAS score, pain and stiffness degrees, activities and functions, and WOMAC scores at week 1 and 4 after treatment in all patients with statistical difference (P < 0.05). Besides, better effect was shown in the treatment group (P < 0.05).

CONCLUSIONSTMIT combined drug therapy could relieve KOA patients' pain, stiffness and joint activities, elevate the overall efficacy. TMIT was easily operated with less injury.

Objective To investigate BAALC(brain and acute leukemia cytoplasmic)gene expression in patients with de novo acute myeloid leukemia(AML)and its clinical significance. Methods BAALC expression was determined by real-time quantitative polymerase chain reaction(RQ-PCR) in 63 de novo AML patients.The association between BAALC expression and therapeutic effect was analyzed.Results The correlation coefficiencies were over 0.99 for standard curves of RQ-PCR method. BAALC expression was detected in 49(78%)AML patients.The peripheral WBC counts,hemoglobin, platelet counts and the bone mahow blast cell percentage at onset in 31 AML patients with high BAALC expression were(26.3?18.1)?10~9/L,(78.3?21.8)g/L,(76.9?64.5)?10~9/L and(61.2?22.3)% and those of 32 AML patients with low BAALC expression were(30.2?21.7)?10~9/L,(81.6?30.9)g/L, (73.9?57.2)?10~9/L,(54.3?16.3)%,respectively.No statistic differences were found between these two groups.The AML patients with normal chromosome karyotypes are more likely to have a high BAALC expression(68%)compared with those with abnormal chromosome karyotypes(23%,?~2=12.093,P= 0.001).AML patients with normal cytogenetics and high BAALC expression shows significant lower CR rate (65%)compared with those with low BAALC expression(84%,?~2=6.573,P=0.013). Conclusion High BAALC expression may define an important risk factor in AML with normal cytogenetics and predicts an adverse prognosis.

Objective To investigate whether the genetic variant rs10830963 of melatonin receptor 1B(MTNR1B)gene is associated with increased risk for gestational diabetes mellitus (GDM).Methods Eighty-seven GDM subjects(GDM group)and 91 normal pregnant women (control group)were randomly recruited form Women and Children's Hospital of Quzhou,Zhejiang Province,China.The allele and genotype frequencies of the rsi0830963 in MTNR1B gene were determined in all participants with PCR amplification and DNA sequencing.The allele and genotype frequencies of rs10830963 were compared to determine their differences between GDM subjects and normal controls.In addition,multiple linear regression was conducted to investigate the association patterns of the risk allele with fasting glucose and HbAlc levels.Results Both GG genotype and G allele frequencies of the rs10830963 loci in the GDM group were significantly higher than those in the controls,and women with G allele and GG genotype were associated with increased GDM risk(OR=1.53,95％ CI:1.005-2.324,P=0.047 and OR=2.16,95％ CI:1.052-4.434,P=0.034 respectively).After adjusting for age,body mass index before pregnancy,and family history of diabetes mellitus,women carrying GG genotype still had a higher GDM risk(OR =2.07,95％ CI:1.048-4.372,P =0.022).Multiple linear regression showed that the rs10830963 G allele was positively correlated with higher levels of fasting glucose(0.068 mmol/L,P=0.015)and HbAlc(0.073％,P=0.028).Conclusions Genetic variant rs10830963 in MTNR1B gene may contribute to the susceptibility to GDM in Chinese population and the rs10830963 G allele is a risk factor for the GDM susceptibility.

Objective To explore the reliability of relevant electrocardiogram(ECG) indexes in evaluating isoprenaline(ISO)-induced rat acute ischemic myocardial injury and provide reference for future scientific applications of these models. Methods Seventy male Wistar rats were randomly equally assigned to ten groups according to their body weight: 5,10,20,40,80,160,320,640, 1280 and 2560 μg/kg dose groups. All rats were tail intravenously given corresponding doses of saline diluted isoprenaline according to their body weight. Standard limb Ⅰ , Ⅱ, Ⅲ-lead ECG of all rats were recorded before, immediately after and 1,24,and 72 hour after injection, respectively.Changes of heart rate, T-wave amplitude of Ⅱ -lead and Q-T interval were measured. Results Significant differences were found in heart rates, T-wave amplitudes and Q-T intervals at different time points(F = 15.03,11.28,13.64, all P ＜ 0.01 ), while differences among the ten ISO-dose groups were statistically insignificant (F= 1.45, 1.17,1.09, all P ＞ 0.05). No interaction between observation time and ISO dose was observed on heart rates, T-wave amplitudes and Q-T intervals(F= 0.79,0.82,0.59, all P ＞ 0.05). Immediately after injection of ISO, the heart rates were significantly increased compared with that of pre-injection in all groups(all P ＜ 0.05), of which 320 and 640μg/kg dose groups increased most significantly [(550 ± 47), (521 ± 43)times/min]. T-waves decreased significantly compared with that of pre-injection (all P ＜ 0.01 ), and 20 μg/kg dose and above groups decreased particularly evident, and partly inverted. Q-T intervals of rats in each group were significantly shorter than that of pre-injection(all P ＜ 0.01 ), and 320, 640, 1280 μg/kg groups shortened more pronounced[(0.070 ± 0.006),(0.072 ± 0.005), (0.068 ± 0.005)ms]. One hour after injection, the heart rate of rats in each group decreased,except 320 and 640 μg/kg dose groups[(518 ± 43), (487 ± 36)times/min], which were still higher than that of pre-treatment[(450 ± 40), (448 ± 51 )times/min, all P ＜ 0.05], the rest groups no longer had significant differences (all P ＞ 0.05). ECG T-wave in each group was significantly recovered compared with that of instantly medication (all P＜0.05), and 40 μg/kg dose and above groups recovered more than a big margin, but there were still differences compared with that of pre-treatment (P ＜0.05), while T-waves of 40 μg/kg dose and below groups had returned to the level of pre-treatment. Q-T interval in each group had varying degrees of recovery, except 1280 and 2560 μg/kg dose groups[(0.080 ± 0.004), (0.076 ± 0.011 )ms]which were still less than that of pre-treatment[(0.086 ± 0.007),(0.085 ± 0.006)ms, all P ＜ 0.05], other groups had no significant difference compared with that of pre-treatment (all P ＞ 0.05). Twenty-four hours after injection of ISO, the heart rates of 1280 and 2560 μg/kg dose groups [(389 ± 31 ), (398 ± 23)times/min]decreased significantly compared with that of pre-treatment[(427 ± 43), (438 ±26)times/min, all P ＜ 0.05], while other groups had returned to the level of pre-treatment. Seventy-two hours after injection of ISO, the heart rates, T-wave amplitudes and Q-T intervals of all doses groups had returned to the level of pre-treatment (all P ＞ 0.05). Conclusions There has no significant ST segment in the electrocardiogram of rat.Isoprenaline has an exact effect on shortening Q-T interval. T-wave amplitude and Q-T interval can be used as reliable indexes of ECG for assessment of this animal model.
