Hypoxia is a common characteristic in solid tumors. With the regulation of the transcription of multiple target genes, HIF-1αplays an important role in the energy metabolism, proliferation, and apoptosis of tumor cells. HIF-1αcontributes to the adapta-tion of tumor cells and tissue to hypoxia stress through these processes. It also promotes tumor angiogenesis and increases their inva-sive ability and the resistance to radio and chemotherapy. Cancer treatment targeting on HIF-1αis an important potential therapy.

OBJECTIVE:To evaluate the efficacy of Yinzhihuang injection combined Oxymatrine injection for patients with acute icteric viral hepatitis.METHODS:100 patients with acute icteric viral hepatitis were randomly divided into two groups:50 patients in the the trial group were treated iv with Yinzhihuang injection 30 mL plus Oxymatrine sterile injection powder 600 mg qd for 30 days,and the another 50(control group) treated iv with Potassium magnesium aspartate 20 mL and Diammonium glycyrrhizinate injection 30 mL qd for 30 days.RESULTS:The cure rate and improvement rate in the trial group was signficantly higher than in the control group(P

Objective:To assess the efficacy of terbinafine combined with fluconazole in the treatment of recurrent vulvovaginal candidiasis(RVVC).Method:94 patients with recurrent vulvovaginal candidiasis were randomly divided into three groups.30 cases in the terbinafine monotherapy group were treated with an oral 250mg-dose of terbinafine once daily; 31 cases in the fluconazole monotherpy group were treated with an oral 150mg-dose of fluconazole once daily;33 cases in the combined therapy group were given terbinafine and fluconazole together,and the usage and dosage were the same as those of the monotherapy groups.The treatment period of the three groups was 7 days.The efficacy was evaluated in the second week,sixth month and twelfth month after the treatment.Result:In the second week or sixth month or twelfth month after the treatment,the clinical cure rate,clinical effective rate and fungous clearance rate of the combined therapy group were higher than those of the monotherapy groups,which had statistically significant difference.Conclusion:The combined therapy with terbinafine and fluconazole can effectively improve the clinical signs and symptoms of RVVC patients and eliminate candida,which is more effective than the monotherapy with terbinafine or fluconazole.

OBJECTIVE: To observe the effects of Xuebijing injection on serum level of C reactive protein(CRP) and the incidence of sepsis in patients with severe burn.METHODS: Eighty cases with severe burn injury were randomly assigned to receive routine therapy alone(control group,n=40) routine therapy in combination with Xuebijing injection 100 mL q.d(treatment group,n=40) for 14 days.The level of CRP at 0,3,7,and 14 days were recorded and the incidences of sepsis in the two groups were analyzed statistically.RESULTS: At 7 days,the level of CRP in the treatment group was significantly lower than in the control group(P

OBJECTIVE To investigate the current situation and epidemiological features of syphilis among inpatients in our hospital since 2003.METHODS This study was retrospective.The data were obtained from the inpatients′ files from Jan 2003 to May 2006,All patients with syphilis were analyzed with epidemiological methods.RESULTS Of the 127 586 inpatients screened for syphilis,740(0.58%) were positive,in which 13 were congenital syphilis,371 were latent syphilis and 356 were dominant syphilis.The yearly syphilis positive rate steadily increased,especially the proportion of latent syphilis,being higher among male(0.70%) than female(0.49%)(OR=1.47).The syphilis positive rate of the elder was higher than that of the younger.The syphilis occurred in all departments and all age groups.CONCLUSIONS There is a need for a routine syphilis screening among all inpatients in order to prevent the misdiagnosis of syphilis among them,especially for the latent syphilis.This could be benefit for the latent syphilis patients to get treatment earlier and minimize the spreading of syphilis.

ObjectiveTo explore the clinical effect of oral administration and external application of traditional Chinese medicine on early stage of osteofascial compartment syndrome. Methods56 early osteofascial compartment syndrome patients had assigned in two groups randomly, each group had 28 patients. The treatment group used topo-application Xiaoyu tincture,after aseptic gauze sodden by physic liquor,affected limb would coverd by the aseptic gauze and change of dressing every two hours,oral administration of Xingqihuayu decoction. The control group used 250ml of 20％ mannitol with dehydration therapy,two times everyday;654-2 bullet 10ml to intramuscular injection,three times every day. ResultsAfter the treatment,the results showed that the treatment group was much better than the control group at the time of ache abatement,swelling regression and disappear of all levels injury, arteriae dorsalis pedis changing. The difference had statistical significance( P ＜ 0.05). ConclusionTopo-application chinese drugs pharmaceutics of Xiaoyu tincture and oral administration of Xingqihuayu decoction was a available nonspecific treatment to early osteofascial compartment syndrome.

Objective To study the condition of benzodiazepines use in generalized anxiety disorder (GAD) patients and the relationship with the first benzodiazepine(BZD) prescription.Methods 70 outpatients with GAD were investigated retrospectively and divided into either research group( n = 54, M21, F33; age (18 ～73)year) or control group( n= 16,M7,F9; age( 18 ～53)year) based on whether the first prescription included BZD or not.Results The duration and dose of BZD used in research group ( separately (9.7 ± 4.4) months, ( 1.6 ± 0.7 ) mg/d) were significantly higher than those in control group ( separately(2.3 ± 2.4) months, (0.9 ± 0.9 ) mg/d) (P＜0.01).The long-term use of BZD was positively related to whether the first prescription include BZD or not,patients' insomnia on first visit,the duration of follow-up and the dose of BZD,which showed significantly difference (P＜ 0.05 ).The standardized rates of long-term use of BZD and dependence in research group were significantly higher than those in control group (P ＜ 0.01 ).Conclusion Prescribing BZD on the first visit is partly responsible for the long-term use of BZD and doctors should better be very careful of prescribing BZD on first visit.

Objective To investigate the potential of AFP-targeted ultrasmall superparamagnetic particles of iron oxide (USPIO) molecular probe in specific detection of hepatocellular carcinoma (HCC) with MRI.Methods The targeted probe was synthesized by conjugating AFP antibody with modified USPIO.Two groups treated with AFP-USPIO and USPIO were set up in the study.The HepG2 cells were incubated with AFP-USPIO or USPIO (100 μg/ml) respectively with the dosage of 50 μ1,100 μl or 150 μl for 4 hours,followed by MR imaging in vitro.The signal-noise ratio (SNR) of the cells on T2-weighted image (T2WI) was measured.The rat models with orthotopic HCC were divided into two groups with 5 rats for each group at random.Pre-and post-contrast enhanced (after 1 hour) MR imaging were performed with caudal vein injection at a dosage of 20μg/ml.The contrast noise ratio (CNR) on T2WI and the difference of CNR between pre-and post-enhancement or between both groups were calculated.The relationship of SNR or CNR with the iron particles in cells or tumors was confirmed by Prussian blue iron staining.Results Cytology experiment showed the SNR in both groups was decreased with the increase of the dosage of AFP-USPIO or USPIO,indicating statistically significantdifference in SNR among three different doseage groups (P＜0.05).Prussian blue iron staining showed that the iron particles in cells were increased with the increase of AFP-USPIO dosage,and was negatively correlated with SNR (P=0.00,r=-0.926).However,the iron particles were less in cells in USPIO group.The CNRs of liver tumors in Wistar rat of pre-and post-AFP-USPIO injection were 2.05±0.88 and 0.96±0.31 respectively,indicating a significant difference (P=0.028,t=3.380).However,the CNRs in USPIO group,2.25±1.50 and 2.57±1.49,showed no statistical difference (P=0.275,t=1.263).The CNR after enhancement also had a statistical difference between both groups(P=0.042,t=3.487).Pathological results confirmed more iron particles in tumor tissues in AFP-USPIO group,whereas less in USPIO group.Conclusion AFP-USPIO molecular probes can initiatively target to the HepG2 cells and the liver cancer of rat models expressing AFP,which may help to achieve the specificity of MR imaging in the diagnosis of HCC.

ObjectiveTo explore the personality traits of Han Chinese women with recurrent depression.MethodsAssessed by the Big Five Inventory (BFI),a comparison research was conducted between 118 Han Chinese women with recurrent depression and 65 sex,race and culture background matched health controls.Results Han Chinese women with recurrent depression scored lower in extraversion,conscientiousness and openness ( 17.93± 5.43,30.24 ± 5.94,30.03 ± 7.33 ) than matched controls ( 20.72 ± 3.79,31.94 ± 3.84,32.75 ± 5.32 ),while scored higher in neuroticism (21.38 ± 3.91) than the later one ( 27.57 ± 6.19 ).A binary logistic regression model,with group (case vs.control) as dependent variable and extroversion,conscientiousness,openness and neuroticism as independent variables,was built to assess each personality dimension's independent impact on recurrent depression.It came out to be that only extraversion ( OR =0.881,95％ CI =0.083-0.966,P=0.007) and neuroticism ( OR =1.225,95％ CI =1.134-1.323,P ＜ 0.01 ) were statistically significantly associated with recurrent depression ( P＜ 0.05 ).ConclusionIn the big five personality model,extraversion and neuroticism might act as independent personality traits to impact Han Chinese women with recurrent depression in a positive and negative way respectively.

To study the effects of mouse cytomegalovirus (MCMV) on the in vitro maturation, fertilization, cleavage and blastula formation of mouse oocytes, the immature oocytes were infected in vitro by MCMVs of different dosages (100 TCID(50), 10 TCID(50) and 1 TCID(50)). The oocytes were then observed for in vitro maturation, fertilization, cleavage and blastula formation and the ultrastructural changes after the culture with the viruses. Our results showed that no significant differences were found in IVM, IVF, cleavage and blastula formation among the groups treated with of virus of various dosages. And ultrastructural abnormality was observed in the oocytes treated by 100 TCID(50) of viruses. It is concluded that MCMV did not have any conspicuous effects on IVM, IVF, cleavage and blastula formation of murine immature oocytes.
