Objective To analyze the relationships between the drinking water fluoride and bone mineral density (BMD), and serum osteocalcin (BGP) and to explore the BMD and serum BGP as significant early screening biomarkers for fluorosis especially for early bone damage in endemic fluorosis areas. Methods Wamiao (severe endemic fluorosis area, as fluoride exposed group) and Xinhuai (non endemic fluorosis area, as control group) Village were selected in 2006. One hundred and fouty-six objects were chosen from 2 villages (103 in Wamiao, 43 in Xinhuai). The sex, age, body height, body weight, drinking water fluoride in each object's household well, BMD, and serum BGP were investigated, and the dose-response relationships were analyzed between the drinking water fluoride and BMD, and serum BGP. CurveExpert 1.3 Software was used to fit the dose-response relationships between the rate of abnormal BMD, the rate of abnormal serum BGP, and the drinking water fluoride. Results The levels of drinking water fluoride in males' and females' families in fluoride exposed group were [(2.38±0.68), (2.62±0.91 )mg/L] significant higher than that in control group [(0.35±0.08), (0.36±0.07)mg/L], the difference being statistically significant(t values were 14.27 and 11.08,and P<0.01, respectively). BMD in males in fluoride exposed group [(0.78±0.07)g/cm2] was significant lower than that in control group[(0.83±0.08)g/cm2], the difference being statistically significant (t=2.37,P<0.05). Serum BGP in males and females in fluoride exposed group [(4.17±0.67), (4.11±0.57) μg/L] were significant higher than that in control group [(1.48±0.40), (1.44±0.39)μg/L], the difference being statistically significant (t values were 17.64 and 19.40, and P<0.01, respectively]. BMD in the group with drinking water fluoride≥2.92 mg/L[(0.66±0.15 )g/cm2] was significant lower than that in the group with drinking water fluoride<0.42 mg/L [(0.76±0.12)g/cm2], the difference being statistically significant (P<0.01). The levels of serum BGP in the groups with the drinking water 0.42-,2.05-, ≥.92 mg/L[(3.83±1.07), (4.22±0.72), (3.99±0.63) μg/L] were significant higher than that in the group with the drinking water<0.42 mg/L [(1.44±0.37) μg/L], the difference being statistically significant (P<0.01). The equation for the dose-response relationship between the drinking water fluoride and the rate of abnormal BMD was y=(0.284-0.058x)-1.260, r=0.999 94; and y=100.05/(1+78.62e-4.5x), r=0.999 99 for the drinking water fluoride and the rate of abnormal serum BGP. Conclusions There were significant dose-response relationships between drinking water fluoride and BMD and serum BGP. It indicated that BMD and BGP might be considered as early screening biomarkers for endemic fluorosis, especially for the bone damage.

OBJECTIVETo observe the therapeutic effect of Huoxue Jieyu decoction (HJD) on patients with depression after craniotomy.

METHODSNinety patients were randomly divided into 2 groups according to the sequence of their consultation. The 45 patients in the treated group were treated with conventional symptomatic treatment plus oral administration of HJD, and the 38 patients in the control group were treated in the same way but with chlorimipramine (anafranil) instead of HJD. Hamilton depression (HAMD) scores before and after treatment, occurrence of adverse effects and long-term therapeutic effect of treatment were observed.

RESULTSThe score of HAMD was insignificantly different in 2 groups before and after treatment (P >0.05), but the occurrence of adverse effects between them was significantly different (P < 0.01).

CONCLUSIONThe therapeutic effect of HJD on depression was similar to that of anafranil, but HJD has less adverse effect and more stabilized long-term effect.

In order to understand the porcine epidemic diarrhea virus (PEDV) origin and variant characteristics in Liaoning province,diagnosed by PCR,separated by Vero cell,and identified by cell pathological observation,RT-PCR and S gene sequence analysis,1 PEDV strains (LN-2015-1) was successfully isolated from a pig farm of Liaoning province.Analysis of S gene sequence showed that compared withCV777 strain,there were the longest 9 bp insertion,6 bp deletion and 13 bp continuous mutation in addition to point mutation.There also were the longest 3 AA insert,2 AA deletion,and 3 AA or more continuous mutation.The epitope analysis showed that there were 16AA mutations in the 5 epitope regions.Homology analysis show that it had the highest sequence similarity of 99.2％ with HB-HA2015 strain,higher sequence similarity of 98.5％-98.8％ with the domestic and foreign representative strains isolated since 2010,and lower sequence similarity of 93.2％-95.6％ with the traditional strain isolated before 2010;the phylogenetic analysis showed that LN-2015-1 was clustered into the same group with home and abroad variation strain in recent years,and formed a small subgroup with HB-HA2015 at the same time.The evolutionary distance was far from the traditional strains.

OBJECTIVESTo establish a transplanted tumor producing HCV NS3 protein in mice and study the therapeutic effect of minigene vaccine based on invariant chain substitution.

METHODSSP2/0-NS3 cells expressing HCV NS3 antigen were injected subcutaneously into BALB/ c mice. After three days of inoculation, different therapeutical reagents were injected intramuscularly into different groups of mice. The boost immunization was carried out two weeks after the first immunization. The efficiency of HCV NS3 Th1 minigene vaccine was estimated after 60 days observation.

RESULTSFor saline, pCI-neo, pHCV-NS3 and pHCV-NS3-Th1 treated groups, the induction period needed for tumor growth was 16.17+/-2.55, 14.40+/-1.82, 16.75+/-2.36, and 24.00+/-5.57 days (t =2.623, P =0.034 vs saline, t =3.713, P =0.010 vs pCI-neo and t =2.425, P =0.045 vs pHCV-NS3) respectively. The tumorigenesis rates were 100%, 100%, 57.1% (8/14, chi2 = 6.190, P = 0.013 vs saline and chi2 = 6.608, P = 0.010 vs pCI-neo) and 46.7% (7/15, chi2 = 9.707, P = 0.002 vs saline and chi2 = 10.311, P = 0.001 vs pCI-neo ) respectively. The survival rates were 0, 0, 50.0% (7/14, chi2 = 5.787, P = 0.016 vs saline and chi2 = 9.333, P = 0.002 vs pCI-neo) and 53.3% (8/15, chi2 = 6.651, P = 0.010 vs saline and chi2 = 10.311, P = 0.001 vs pCI-neo) respectively. The average tumor diameter of the pHCV-NS3-Th1 treated group was significantly smaller compared with the control groups and the pHCV-NS3 treated group (P =0.001). Moreover, the average survival time of tumor-bearing mice immunized with pHCV-NS3-Th1 was 6 days longer compared with the saline treated group, 12 days longer compared with the pCI-neo treated group (P =0.001), and 6 days compared with the pHCV-NS3 treated group.

CONCLUSIONHCV NS3 Th1 epitope vaccine might be a potential biotherapy candidate against HCV infection.

OBJECTIVETo study the effect of angiogenesis inhibitor and its combine with chemical drug in suppressing the growth of adenoid cystic carcinoma (ACC).

METHODSAcc-M cells were inoculated subcutaneous into BABL/C nu/nu mice. The mice were divided into control, different dose of TNP-470 treatment groups, 5-Fu treatment group and TNP-470 plus 5-Fu treatment group. Treatments were given 48 hours after inoculation. The mice were sacrificed on the 22nd day and excised tumors were weighted. Tumors were also investigated by immunohistochemistry and ultrastructural observations.

RESULTSTNP-470 100 mg/kg/qod efficiently inhibited the growth of Acc-M tumors. TNP-470 30 mg/kg/qod combined with 50 mg/kg/week 5-Fu also resulted in significant growth inhibit of the tumors. TNP-470 suppressed tumor growth by inhibiting neovascularization, therefore inducing apoptosis of Acc-M cells. All experimental groups had different degrees of VEGF and bFGF express.

CONCLUSIONSince ACC is a slow developing tumor, blood supply is not so sufficient as sarcomas. Angiogensis inhibitor may inhibit its growth in high dosage. Combining medium dosage of angiogensis inhibitor with chemical drug may have synergistic result in inhibiting ACC growth.

OBJECTIVETo develop a colon-specific prodrug of Indomethacin microbially triggered, carry out in vitro/in vivo evaluation of drug release, and appraise its inhibitory effect on liver metastasis from colon cancer.

METHODSIndomethacin prodrugs were synthesized and characterized by FTIR and NMR, and dissolution test simulating gastrointestinal tract was employed to screen the colon-specific prodrug. Then, the pharmacokinetic profile of portal vein and peripheral blood in Sprague-Dawley rats was studied. Lastly, the inhibitory effect on liver metastasis from colon cancer in nude mice was observed.

RESULTSThe chemical structure characterized by FTIR and NMR demonstrated that six kinds of indomethacin-block-amylose with different drug loading (IDM-AM-1-6) were synthesized, among which IDM-AM-3 was degraded 1.3%, 9.3% and 95.3%, respectively, in simulated gastric fluid for 4 h, small intestine for 6 h, and colon for 36 h. The pharmacokinetic test of IDM-AM-3 showed that absorption was delayed significantly (P < 0.01), peak time [(11.35 + or - 2.45) h], elimination half-life [(16.74 + or - 4.04) h] and mean residence time [(22.27 + or - 0.52) h] were significantly prolonged (P < 0.01), as well as peak serum concentrations [(9.69 + or - 2.40) mg/L] and AUC(0-t) [(236.7 + or - 13.1) mg x L(-1) x h] were decreased markedly (P < 0.01) as compared with those of IDM regarding to portal vein. Additionally, its AUC(0-t) in peripheral blood was remarkably lower than that in Portal vein (P < 0.01). The tumor suppression observation showed that it could remarkably reduce the number of liver metastases in contrast to IDM (P < 0.05).

CONCLUSIONColon-specific IDM-AM-3 possesses advantage of sustained release in portal vein providing some experimental basis for colon-specific delivery system applied to sustained release in the portal vein.

OBJECTIVETo summarize the experience in diagnosis, prevention and treatment of carcinoma arising from congenital biliary duct cyst.

METHODSThe clinical and pathological data of 185 patients with congenital biliary duct cyst admitted to Chinese PLA General Hospital were analyzed retrospectively.

RESULTSAmong 185 patients, twenty-seven cases had carcinomas arising from congenital biliary duct cyst, and the frequency of malignant transformation was 14.6%, which closely related to the age (P < 0.001). The incidences of malignancy for different age groups were: 0 for 0-9 age group, 5.1% for 0-19, 9.1% for 20-29, 16.2% for 30-39, 26.7% for 40-49, 33.3% for 50-59, and 50% for over 60, respectively. Six patients had the history of cyst-enterostomy. Abdominal pain, fever, jaundice and weight loss were the main clinical manifestations. Abdominal ultrasonography, CT, MRI or magnetic resonance cholangiopancreatography, MRCP and endoscopic retrograde choledochopancreatography (ERCP) were the main diagnostic methods. For twenty patients (74.1%), a definite diagnosis was made preoperatively, but it's hard to make an early diagnosis. Nine patients (33.3%) underwent curative resection.

CONCLUSIONSCongenital biliary duct cyst is a premalignant lesion, and the incidence of carcinogenesis increases remarkably with age. The most effective method for prevention of carcinogenesis in choledochal cyst is complete excision of choledochal cyst during childhood, and the prognosis is poor for patients with biliary malignancy.

OBJECTIVETo evaluate the incidence and severity of perioperative complications in elderly patients with radical prostatectomy (RP).

METHODSA total of 242 patents underwent RP for prostate cancer were retrospectively assessed, whose clinicopathologic factors and perioperative complications were retrieved from the medical records. The mean age in the elderly group (n = 163) and control group (n = 79) were (73.2 ± 2.4) and (63.2 ± 4.8) years, respectively. The clinicopathologic factors including Charlson comorbidity index and preoperative prostate specific antigen were statistically significant different. The difference of clinicopathologic factors and perioperative complications between the elderly group (≥ 70 years old) and control group were statistically analyzed using the SPSS 17.0.

RESULTSThe incidence of perioperative complications was 23.5% in the elderly group and 22.7% in the control group. Except for gross hematuria (there were 12 cases in elderly group and 1 case in control group, respectively, χ(2) = 3.89, P < 0.05) and perioperative transfusion (there were 36 cases in elderly group and 7 cases in control group, respectively, χ(2) = 6.37, P < 0.05), there was no significant difference in each kind or total of perioperative complications.

CONCLUSIONThe elderly patients underwent RP in experienced center are not associated with higher or more serious perioperative complications.
