ObjectiveTo observe the effect of integrated traditional Chinese medicine therapy on pelvic inflammation. Methods40 patients of chronic pelvic inflammation were as the group of integrated traditional Chinese medicine therapy and received Chinese herbal medicine treatment (by taken orally, clysis and hot compress), acupuncture, mental state therapy etc. Other 36 cases were as the control group and only received Chinese herbal medicine treatment by taken orally. Then effects of two groups were compared. ResultsIt shows that the group of integrated traditional Chinese medicine therapy got obviously better results than the control group (P<0.01). ConclusionsThe integrated traditional Chinese medicine therapy is more effective on chronic pelvic inflammation.

Four compounds were isolated from the 70% EtOH extract of Ardisia crispa by using various chromatographic techniques, including silica gel, ODS and semi-preparative HPLC. The structures of 1-4 were elucidated based on physicochemical properties and spectroscopic data. These compounds were defined as crispalactone A (1), (+)-pinoresinol (2), 3,5-dimethoxy-4- hydroxyphenol-1-O-β-D-glucopyranoside (3) and (+)-schizandriside (4). Compound 1 is a new γ-valerolactone derivative, and compounds 2-4 are firstly isolated from Ardisia crispa.

The potential biodegradation of crude oil was assessed based on the development of a fermentative process with a strain of Pseudomonas aeruginosa which produced 15.4 g/L rhamnolipids when cultured in a basal mineral medium using glycerol as a sole carbon source. However, neither cell growth nor rhamnolipid production was observed in the comparative culture system using crude oil as the sole carbon source instead. As rhamnolipid, an effective biosurfactant, has been reported to stimulate the biodegradation of hydrocarbons, 1 g/L glycerol or 0.22 g/L rhamnolipid was initially added into the medium to facilitate the biodegradation of crude oil. In both situations, more than 58% of crude oil was degraded and further converted into accumulated cell biomass and rhamnolipids. These results suggest that Pseudomonas aeruginosa could degrade most of crude oil with direct or indirect addition of rhamnolipid. And this conclusion was further supported by another adsorption experiment, where the adsorption capacity of crude oil by killed cell biomass was negligible in comparison with the biologic activities of live cell biomass.

Objective To establish a high performance liquid chromatography (HPLC) method for determining phenytoin concentration in epilepsy patients' plasma,and compare this method with chemiluminescence microparticle immunoassay (CMIA),and to evaluate the consistency of the two methods.Methods HPLC and CMIA methods were applied to determine the plasma concentration of phenytoin in 60 epileptic patients,respectively.The difference of results was analyzed by two-side paired t-test,and then the correlation and consistency of the two methods were investigated with Passing-Bablok regression and Bland-Altman method.Results There was no significant difference between the results of the two methods (P ＞0.05).The regression equation of the determination results by HPLC (Y) and CMIA (X) was Y=0.992 9X +0.143 7 (R2 =0.992 6,n =60),which indicated the correlation of the two methods was good.Bland-Altman analysis showed that the consistency of the two methods for determining was good.Conclusion HPLC and CMIA method in monitoring plasma concentration of phenytoin have good correlation and consistency.Both methods can be used for therapeutic drug monitoring of phenytoin.

Objective To establish and evaluate criteria applied to review of complete blood counts (CBC)and differential results from automated hematology analyzers.Methods Temporary criteria were established by using alarm system of XE-2100 automated hematology analyzer and by consulting the 41 suggested rides of international consensus group.2 795 out-and in-patient samples were run as clinical samples.Stained blood films were prepared and manual differential with smear review were performed on all samples.Statistical analysis was done for each temporary rule and instrument flag which indicated abnormal cell quantity and morphology.Results Of all rules,instrument flags of ‘Immature Gran/Left Shift?’, ‘ Atypical Lympho?’and‘NRBC(nucleated red blood cell)?’showed most frequent false positive and false negative instrument flag.Evaluation on rnles about cell quantity change showed false positive and false negative rates were both low.Results of morphology evaluation showed that true positive rate was 17.44%, false positive rate was 15.82%,true negative rate was 63.49%,false negative rate was 3.25%.‘ Atypical Lymphocyte?’,‘Immature Gran?’and‘blast?’were the most frequent false positive flags.According to those results and clinicians opinions,our hematology review criteria for action following automated CBC and leukocytes differential was established.Conclusions The hematology review criteria have high true positive rate and low false negative rate.To clinical hematology laboratory using automated hematology analyzer,new criteria can reduce work load,bring lower false negative rate and higher work efficiency.

Objective To determine the pharmacokinetic interaction between cefalor and bromhexine in healthy Chinese volunteers. Methods Twelve subjects received a cefaclor (CEF) treatment, a bromhexine (BHX) treatment, and a co-treatment of CEF and BHX with a 3 × 3 Latin square design. The wash-out time between periods was 14 days. The plasma and urine drug concentrations of CEF and BHX were detected by HPLC-UV and LC/MS, respectively. Results All the 12 volunteers completed the study. There were no significant differences in AUC0-t and Cmax of CEF in logarithm between the single administration group of CEF and the co-administration group of CEF with BHX. Two one sided t-test showed that CEF was bioequivalent in the 2 groups. There were no significant differences in tmax, MRT, t1/2, and Clr between the 2 groups. Vd/F was significantly lower in the single CEF group than in the co-administration group of CEF and BHX. There were no significant differences of AUC0-t and Cmax of BHX in logarithm between the single administration group of BHX and the co-administration group of BHX with CEF. Two one sided t-test showed that BHX was bioequivalent in the 2 groups. There were no significant differences in tmax, MRT, t1/2, Vd/F, and Clr between the 2 groups. Conclusion There is no significant pharmacokinetic parameter change in the drug absorption, metabolism, and excretion, but Va/F of CEF significant increases in the co-administration of CEF with BHX. The co-administration of CEF and BHX has no adverse drug interaction. The increase of Vd/F may be a favorable drug interaction, which may be the mechanism of the synergistic effect of the 2 drugs.

The systematic treatment based on gemcitabine plus cisplatin is recommended as the current standard chemotherapy for unresectable or metastatic biliary tract cancers.However,the exact benefits from the recognized regime are still dismal.We thus elicit this study in an attempt to analyze whether targeted therapy coupled with various chemotherapy could produce improvement of survival benefits.The clinical trials were searched electronically from databases till July 2016 published in English and Chinese.Nine hundred and sixty-four patients from 7 trials were identified in our analysis.The overall analysis achieved a significantly higher overall response rate (ORR) among the patients treated with targeted drugs plus chemotherapy than chemotherapy alone (OR=1.87;95％ CI:1.37-2.57;P=0.000),but failed in the overall progression-free survival (PFS) [mean difference (MD)=0.63;95％ CI:-0.45-1.72;P=0.26] and overall survival (OS) (MD=-0.67;95％ CI:-2.54-1.20;P=0.49).In the sub analysis,better ORR was obtained with the addition of EGFR (OR=1.75;95％ CI:1.20-2.56;P=0.004) and VEGFR (OR=2.5;95％ CI:1.28-4.87;P=0.007) targeted therapy.Furthermore,the sub analysis of EGFR target showed an significant improvement on PFS (MD=l.36;95％ CI:0.29-2.43;P=0.01).No significant differences were observed in the incidences ofneutropenia (OR=1.37;95％ CI:0.89-2.12),thrombocytopenia (OR=l.40;95％ CI:0.83-2.39),anemia (OR=l.21;95％ CI:0.62-2.38),peripheral neuropathy (OR=1.52;95％ CI:0.81-2.88),increased AST/ALT (OR=l.40;95％ CI:0.82-2.39) as well as fatigue (OR=1.65;95％ CI:0.96-2.84) in either of the treatment groups.In conclusion,better ORR associated with chemotherapy combined with targeted therapy (both targeting EGFR and VEGF) is found in the present mcta-analysis without the cost of increased unacceptable toxicities,but regretfully not for the OS.The sub-analysis of targeting EGFR instead of VEGF obtains a superior PFS.Otherwise,there is no statistically significant difference in the overall PFS between the combination regime and chemotherapy alone.Given the paucity of favorable data,we need further studies to characterize optimal targeted agents to confirm the potential value to biliary tract cancer.

Objective To prepare anti-recombinant protein antibody from immunized mice with recombinant nucleocapsid protein (NP) of human influenza A3 (IFV-A3) virus expressed in prokaryotic cell, and to explore the feasibility of utilizing anti-recombinant protein antibody to detect influenza A virus. Methods NP genes of human influenza A virus were analyzed with computer softwares of ClustalX, Antheprot, et al. to determine the antigen city in conserved regions. Three different partial NP genes were harvested and cloned intopET-28(c) plasmid, the recombinant plasmids were induced to express partial NP segments in BL21 cells. The recombinant proteins were purified with Ni-agarose by affinity chromatography and immunized BALB/c mice. The polyclonal antisera harvested from mice were analyzed with Western Blot and immunohistochemistry assays to detect the reactions with IFV-A. Results Three recombinant plasmids were expressed with high yield in BL21 cells, about 15-20 mg/L. Western Blot Results indicated that the three prepared antis era (1:2000) positively reacted within from IFV-A3-infected cells. And immunohistochemistry assays suggested that anti-NP1, anti-NP2, anti-NP3 antisera positively reacted with IFV-A3 or IFV-Al-infected MDCK cells, with titers of 1:640 to 1:1280. Conclusion the recombinant NP of IFV-A3 would induce polyclonal antibodies with high titers in mice. The polyclonal antibodies would cress-react with IFV-A3 and IFV-AI. It is feasible to predict the antigen city with systematical bioinformatics analyses and then induce anti-IFV antibodies with high dilutions, and it is possible to be utilized in the early detection and sub typing analyses of IFV-infections.

OBJECTIVETo investigate the clinical characteristics, treatment modalities and prognostic factors of chordoma in the skull base.

METHODSThe data of 37 patients with chordoma in the skull base treated from 1970 to 2002 were retrospectively reviewed. Twenty-eighty received surgery plus radiotherapy, 8 radiotherapy alone and 1 surgery alone. The total dose of irradiation ranged from 30 - 75 Gy with a median of 60 Gy.

RESULTSThe rates of symptom relief and remarkable tumor regression at the end of radiotherapy were 86.5% and 48.6%, respectively. The nerve and endocrine function recovery was observed in some patients within six months to two years after treatment. The overall 1-, 3-, 5- and 10-year survival were 97.3%, 87.3%, 71.5% and 41.0%, respectively. The overall 1-, 3-, 5- and 10-year survival were 100.0%, 92.9%, 85.7% and 50.8% in patients with palsies of cranial nerves II-VIII, but 100.0%, 75.0%, 45.0% and 0 in patients with dysfunction of cranial nerves IX-XII, respectively (P = 0.04).

CONCLUSIONSurgery is the first option for chordoma, but resection with a safe margin is difficult to achieve due to the special anatomical location of the skull base. Local failure is the main cause of death. Radiotherapy is an important adjuvant for local control. The total dose should not be less than 60 Gy for prophylactic purpose, and more than 70 Gy should be given to patients with recurrence, residual lesions after surgery or those not operated. The injury of cranial nerves IX-XII suggests a poor prognosis.
