Objective To investigate the effects and clinical value of neoadjuvant chemotherapy in patients with locally advanced cervical cancer.Methods 102 cases with locally advanced cervical cancer treated were randomly divided into observation group and control group,the observation group received the surgery after the neoadjuvant chemotherapy,and the control group was given a direct surgical treatment.Operative time,blood loss and postoperative pathologic results were observed,and chemotherapy and toxicity evaluation were made for the observation group.Results The chemotherapy effective rate of the observation group was 74.51％,and the toxicity could be tolerated;the operation time and blood loss of the observation group were significantly lower than those of the control group(all P ＜ 0.05) ;surgical trauma and postoperative complications' occurrence rate of the observation group were significantly lower than those of the control group (all P ＜ 0.05) ; pelvic lymph node metastasis and vaginal cutting edge of the residues of the observation group were significantly lower than those of the control group (all P ＜ 0.05).Conclusion For locally advanced cervical cancer,NACT has a positive significance in reducing the tumor volume,low-er tumor stage,and at the same time reducing the difficulty of operation,surgical trauma,postoperative complications,and preventing recurrence and metastasis,which can be used as a better adjuvant treatment program for locally advanced cervical cancer.

Lycii Cortex, a popular herb medicine in traditional Chinese medicine, is used to treat different inflammation-related diseases. The aim of our work is to find the key constituents inhibiting NF-kappaB, a key regulator of inflammation. In the investigations of cell-based in vitro assays of extracts, we found that both ethyl acetate extract and methanol extract of Lycii Cortex inhibited the TNF-alpha-induced activation of NF-kappaB. Through bioassay-guided fractionation, we identified 4 phenolic amides including trans-N-(p-coumaroyl) tyramine (1), trans-N-feruloyltyramine (2), trans-N-caffeoyltyramine (3), and dihydro-N-caffeoyltyramine (4). Four phenolic amides showed differently inhibitory activities on TNF-alpha-induced NF-kappaB activation. Trans-N-caffeoyltyramine (3) was identified as the key component with an IC50 of 18.41 micromol x L(-1). It was suggested that the hydroxyl group at C-3 in trans-N-caffeoyltyramine might be a key binding site and its C-7,8-double bond might play an important role on NF-kappaB inhibitory activities as the link of the conjugation of pi electrons leading to a partial planar conformation. It might be inferred that the biological activity of compound 3 is attributed to the structure of Michael reaction acceptor containing alpha, beta-unsaturated ketones and benzene along with hydroxyl group in o-diphenol.

Objective To evaluate the therapeutic effect and safety of ureteroscopy pneumatic lithotripsy(PL) and extracorporeal shock wave lithotripsy(ESWL) in the treatment of distal ureteral calculi.Methods 368 cases of distal ureteral calculi were divided into the PL treatment group(178 cases) and the ESWL treatment groups(190 cases).The clinical datas were compared between the two groups.Results PL treatment group 97.19% patients became stone free in 4 weeks,and in ESWL treatment group the stone free rate was 73.16%(P

ObjectiveToexplore the appearance ofmusclecrushinjuryatquantitative ultrasonographic elastography by supersonic shear imaging (SSI).MethodsThe animal experiment was done using a special balloon cuff device to create left hind leg crush injury with a force of 18.6 kPa.Twentythree New Zealand rabbits had crush injury of extremity and survived for 72 hours.SSI quantitative elastography was performed in crushed and no-crushed regions of each rabbit hind leg.Quantitative lesion elasticity was measured in terms of the Young modulus (in kilopascals) at 30 min,2 h,6 h,24 h and 72 h after the release of the crushing pressure.A receiver operating characteristic (ROC) curve analysis was used to assess diagnostic performance.ResultsThe area of crushed region in left hind leg accounted for 2.6％ -3.0％ of body surface area in 23 rabbits.The crushed regions exhibited maximum elasticity values of (19.51 ± 6.74)kPa,(21.47 ± 5.54) Pa,(11.36 ± 5.35)kPa,(15.09 ± 3.31)kPa and (13.72 ± 3.74) kPa,and mean elasticity values of (12.44 ± 3.77)kPa,(13.20 ± 3.60)kPa,(6.80±2.86)kPa,(10.04 ± 2.95)kPa and (6.94 ± 0.97)kPa at 30 min,2 h,6 h,24 h and 72 h after the release of the crushing pressure.Comparing with those of no-crushed regions,they were higher obviously (P＜0.001).ROC curves showed that extremity crush injury was diagnosed by using elasticity value,and the greater the elasticity value,the greater the diagnostic value.Conclusions SSI provides quantitative elasticity measurements,thus adding complementary information that potentially could help in crush injury characterization with conventional ultrasonography.

Objective To determine the plasma urolensin Ⅱ(UⅡ) levels in various types of coronary heart disease and to clarify how the plasma UⅡ levels correlate with the clinical presentation, extent and severity of coronary artery atherosclerosis (CAD). Methods: One hundred and three aged patients undergoing elective diagnostic coronary angiography for proven or clinical suspected coronary heart disease were enrolled in this study. The extent and severity of coronary artery disease were evaluated by vessel score and Gensini score, respectively. Plasma UⅡ levels were measured by radioimmunoassay. Results: The plasma UⅡ levels in the patients with modest to severe coronary stenosis (3.03±0.34 pg/ml, 1.83±0.67 pg/ml) were significantly lower than that in subjects with normal coronary artery (4.80±1.11 pg/ml, P＜0.001). The plasma UⅡ levels in patients with coronary heart disease were also significantly lower than that in patients with insignificant coronary stenosis (P ＜ 0.001). Compared to patients with stable angina pectoris, plasma UⅡ levels in patients with acute coronary syndrome were significantly decreased (1.89±0.51 pg/ml vs 2.42±0.77 pg/ml, P＜ 0.001). Plasma UⅡ levels were found to be negatively correlated with the severity of coronary artery stenosis (r = -0.488, P＜0.001), as well as the vessel score (r = -0.408, P＜0.05) in the patients with CAD. Conclusion: Significant inverse correlations exist between the plasma UⅡ levels, and the extent and severity of coronary artery stenosis. These findings suggest that plasma UⅡ contribute to the development and progression of coronary artery stenosis, and may be a novel marker to predict clinical types, as well as the extent and severity of coronary artery disease in the patients.

Objective To explore the impact of nucleos(t)ide analogue antiviral therapy on anxiety and depression of patients with chronic hepatitis B (CHB),and analyze the related factors.Methods Before nucleos(t)ide analogue antiviral therapy,1 year and 2 years after antiviral therapy,120 CHB patients were investigated with self-rating anxiety scale (SAS) and self-rating depression scale (SDS).The demography data of patients were collected.Serum levels of alanine transaminase (ALT) and hepatitis B virus (HBV) DNA and other biochemical indicators were measured regularly.Results Before nucleos(t)ide analogue antiviral therapy,1 year and 2 years after antiviral therapy,both the mean scores of SAS and SDS became lower gradually (F=12.661 and 22.395,respectively;both P＜0.01).The percentage of patients with SAS and SDS scores more than 50 were 5.8％,4.2％,1.7％ and 13.3％,7.5％,5.0％,respectively.After 2 years of therapy,the anxiety improvement rate of the patients obtained HBV DNA＜1000 copy/mL was 69.0％,while those with HBV DNA≥1000 copy/mL was 22.2％ (x2 =22.325,P＜0.01).Meanwhile,after 2 years of therapy,the depression improvement rate of the patients obtained HBV DNA＜1000 copy/mL was 77.4％,while those with HBV DNA≥1000 copy/mL was 22.2％ (x2 =32.179,P＜0.01).Multiple factors Logistic regression analysis indicated that the odds ratios (OR) of improvement of anxiety and depression in patients with HBV DNA＜1000 copy/mL were 7.751 (95％ CI:3.026-19.853) and 15.069(95％ CI:5.309-42.770),respectively,compared with those with HBV DNA≥1000 copy/mL; and OR of improvement of depression in patients with ALT≤40 U/L waa 4.103 (95％ CI: 1.376 - 12.238).Conclusions Nucleos(t) ide analogue antiviral therapy could improve the anxiety and depression of CHB patients.The HBV DNA negativity is the independent impact factor of improvement of anxiety and depression in CHB the patients.

Objective To explore the cosmetic effect of oncoplastic volume displacement in breastconserving surgery.Methods 43 cases of breast cancer in stages I and Ⅱ with pathological diagnosis by core needle biopsy were operated by extended resection of tumor combined with axillary lymph nodes dissection.Among the patients,wound cavity was repaired by direct skin suture without suture of mammary gland deletion in 22 cases,and another 21 cases were repaired by oncoplastic volume displacement technique in which skin suture followed by freeing remaining breast tissue flap and translocation to repair the mammary defect.All of them were treated with three-dimension conformal radiotherapy,standard chemotherapy and endocrine therapy after operation.3 years after partial removal of breast,a retrospective historical control study had been fulfilled to analyze breast cosmetic results between two groups.Results In direct suture group,the cosmetology score was 4.3 points and fine rate was 40.9% (9/22).In breast reconstruction group.the score was 4.8 points and fine rate was 71.4% (15/21).The breast cosmetic effect in breast reconstruction group was significantly better than that in direct suture group (P<0.01).Conclusion It will get better breast cosmetic results after operation to utilize oncoplastic volume displacement suture technique in breast-conserving surgery.

Objective To investigate the molecular epidemiology of hepatitis B virus(HBV) in child carriers. Methods Blood samples were collected from children under 15 in Jiangsu and Zhejiang provinces. Enzyme immunoassay(EIA) and microparticle enzyme immunoassay(MEIA) were applied to screen hepatitis B surface antigen(HBsAg) positive children. Nested-PCR and real time PCR were used to amplify the HBV S gene and detected HBV DNA loads. S gene sequence and three-dimensional structure were analyzed by the DNASTAR and VMD1.8.6, respectively. SPSS 12.0 software was applied for data processing. Results A total of 64 HBsAg-positive cases were found in the screened children, from which 41 HBV S gene sequences were obtained. The average HBV DNA loads were(4.15±0.79)×10~7 copies/mL in 64 HBV carriers. Among 41 sequences. genotype C, B and B+C accounted for 82.93%(34/41), 12.19%(5/41)and 4.88%(2/41), respectively; and the serotypes were adr(34/39,87.18%), adw(4/39,10.24%) and ayr (1/39, 2.56%) with 2 strains unable to be sub-typed. The most common variants of "a" determinant in HBV S gene were 129 site Q→F(glutamine→phenylalanine), 145 site G→R(glycine→lysine), 131 site S→N(serine→asparagine)and 144 site C→A(cysteine→alanine), and the mutation frequencies were 12.20%(5/41), 4.88%(2/41), 2.27%(1/41)and 2.27%(1/41), respectively . The total mutation frequency was 21.95%(9/41). The S protein spatial structures of 129 site "Q→F" and 145 site "G→R" were entirely different from that of the wild strain. Conclusion Wild strain of HBV(C/adr) is predominant in the children HBV carriers, exhibiting a high replication, and the HBV vaccine should be still effective.
