Objective:To evaluate the efficacy and safety of rosuvastatin and atorvastatin in the treatment of the patients with primary hyperlipidemia in China.Methods:The related literatures in CNKI,VIP,Wanfang medicine network,PubMed/MEDLINE,CBM and Chinese dissertations full text database were retrievaled by computer from the establishment time of database to December 31,2015. Two researchers according to the inclusion and exclusion criteria independently selected the studies and extracted the data and assessed the quality of the literatures.The Revman 5.0 software was used to perform Meta analysis of all effect indicators in various groups.Results:A total of 7 randomized controlled trial (RCT)were included,and there was no significant abnormality in bias evaluation. 8 weeks after treatment, the total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C)and high density lipoprotein cholesterol (HDL-C)levels of the patients in 5 mg rosuvastain group and 10 mg atorvastatin group had no significant differences between before and after treatment (P >0.05);the HDL-C levels of the patients in 10 mg rosuvastatin group and 10 mg atorvastatin group had significant differences between before and after treatment (P < 0.05),but the TG,TC,and LDL-C levels had no significant differences (P >0.05);the TG,TC,LDL-C and HDL-C levels of the patients in 5 mg and 10 mg rosuvastatin groups had no significant differences between before and after treatment (P > 0.05).12 weeks after treatment,there were no significant differences in the TC and LDL-C levels between 10 mg rosuvastatin group and 10 mg atorvastatin group (P >0.05),but there were significant differences in the TG and HDL-C levels (P <0.01).The incidence of adverse reactions of the patients in three groups had no significant differences (P >0.05).Conclusion:5 mg rosuvastatin and 10 mg atorvastatin in the treatment of the patients with primary hypercholesterolemia have similar lipid-lowering effect;with the the increase of the treatment time and the dose,10 mg rosuvastatin can obviously reduce the TG level and increase the HDL-C level of the patients,and the incidence of adverse reactions of two kinds of doses of rosuvastatin has no obvious difference.

Cryptosporidium andersoni ATP-binding cassette (CaABC) is an important membrane protein involved in substrate transport across the membrane. In this research, the nucleotide binding domain (NBD) of CaABC gene was amplified by PCR, and the eukaryotic expression vector of pEGFP-C1-CaNBD was reconstructed. Then, the recombinant plasmid of pEGFP-C1-CaNBD was transformed into the mouse intestinal epithelial cells (IECs) to study the iron transportation function of CaABC. The results indicated that NBD region of CaABC gene can significantly elevate the transport efficiency of Ca2+, Mg2+, K+, and HCO3 - in IECs (P<0.05). The significance of this study is to find the ATPase inhibitors for NBD region of CaABC gene and to inhibit ATP binding and nutrient transport of CaABC transporter. Thus, C. andersoni will be killed by inhibition of nutrient uptake. This will open up a new way for treatment of cryptosporidiosis.

OBJECTIVETo investigate the changes in cellular apoptosis of Peyer's patches in severely scalded mice, and to explore its role in the pathogenesis of gut barrier damage.

METHODSForty BALB/c mice were randomly divided into normal control, 12 post-scald hour (12PSH), 24PSH and 72PSH groups, with 10 in each group. The mice in all PSH groups were inflicted with 20% TBSA full-thickness scald on the back. The mice in all the groups were sacrificed at different time points, and Peyer's patches were harvested from all the mice for HE staining, DNA gel electrophoresis, and flow cytometry ( FCM) examination with FITC conjugated Annexin-v and propidium iodide( PI) staining of cells.

RESULTSHE staining revealed that there were relatively abundant apoptotic cells scattering in Peyer's patches of scalded mice . DNA electrophoresis of Peyer's patches revealed typical " ladder" pattern at all indicated time points in scalded mice. Apoptotic percentage of detached Peyer's patches cells in control and scalded group were (4. 9+/-2. 1)% , (26.7+/-3. 1)% , (21.6 +/-4.0)% ,(12. 8 +/-2.0)% , respectively, and the percentage reached the peak at 12 PSH.

CONCLUSIONApoptosis is a principle modality of cell death of small intestinal Peyer's patches lymphocytes in severely scalded mice, and it might contribute to immunity barrier failure of intestinal wall after severe thermal injury.

The essence of endogenous turbidity in Chinese medicine (CM) is different from cream, fat, phlegm, retention, damp, toxicity, and stasis. Along with the development of modern scientific technologies and biology, researches on the essence of endogenous turbidity should keep pace with the time. Its material bases should be defined and new connotation endowed at the microscopic level. The essence of turbidity lies in abnormal functions of zang-fu organs. Sugar, fat, protein, and other nutrient substances cannot be properly decomposed, but into semi-finished products or intermediate metabolites. They are inactive and cannot participate in normal material syntheses and decomposition. They cannot be transformed to energy metabolism, but also cannot be synthesized as executive functioning of active proteins. If they cannot be degraded by autophagy-lysosome or ubiquitin-prosome into glucose, fatty acids, amino acids, and other basic nutrients to be used again, they will accumulate inside the human body and become endogenous turbidity. Therefore, endogenous turbidity is different from final metabolites such as urea, carbon dioxide, etc., which can transform vital qi. How to improve the function of zang-fu organs, enhance its degradation by autophagy-lysosome or ubiquitin-prosome is of great significance in normal operating of zang-fu organs and preventing the emergence and progress of related diseases.

OBJECTIVETo explore anti-angiogenesis effect of Mer, a member of tyrosine kinase receptor family, and its mechanism.

METHODSHuman Mer full length plasmid was transfected into HMEC-1 cells through liposome. G418 was used to select positive clone. Expression of Mer at mRNA and protein level was detected by real-time PCR and Western-blot, respectively. Transwell and Matrigel were used to evaluate the effect of overexpressed Mer on migration and angiogenesis of HMEC-1 cells. Primary angiogenesis associated factor VEGF-A, VEGF-B, VEGF-C, VEGF-D and VEGFR-1, VEGFR-2 were screened by real-time PCR.

RESULTSAfter G418 selection, the Mer expression in transfected HMEC-1 cells was increased 3.61- and 2.12 fold at mRNA and protein level, respectively. Compared with negative control, the migration of Mer-HMEC-1 was decreased (21 +/- 6 vs 36 +/- 11), and angiogenesis capability on Matrigel significantly decreased. By real-time PCR, the expression of VEGF-C and VEGFR-2 was down-regulated to 44.7% and 25.6% of the negative control.

CONCLUSIONOverexpressed Mer tyrosine kinase receptor can inhibit the migration and angiogenesis of HMEC-1 cells through VEGF-C/VEGFR-2 signal pathway.

Objective To explore the infection and drug sensitivity of ureaplasma urealyticum(Uu)and mycoplasma hominis (Mh)in vaginal secretion of gynecological outpatients.Methods The infection and drug sensitivity test of Uu and Mh in va-ginal secretion samples of 1 800 patients collected from January 2015 to April 2016 were detected with mycoplasma culture i-dentification and counting drug sensitivity kit produced by Zhengzhou Antu Luke Bioengineering Co.,Ltd.Results The positive rate of Uu(57.27%)was significantly higher than that of Mh(2.78%,χ2=33.69,P<0.001).The positive rate of mycoplasma was highest in the age group of 31~35(77.09%),but that of Uu was highest in the age group of 21~25 (65.83%)and that of Mh in 36~40 years old group(9.09%),in addition that of multiple infection by Uu and Mh was highest in less than 20 years old group(20.51%).There were statistical difference for Un,Mh and co-infection by Un and Mh between age groups(χ2=15.505~36.574,P<0.01).The top three drugs sensitive for mycoplasma were josamycin, minocycline and doxycycline and that last three ones were clindamycin,thiamphenicol and sparfloxacin.The drug sensitive rates for 12 antibiotics against Uu were higher than those against co-infection by Uu and Mh,but those of erythromycin,gat-ifloxacin,azithromycin,clarithromycin and Luo Hongmei against Mh were lower than those against co-infecion of Uu and Mh.Conclusion The detection of mycoplasma and drug sensitivity in vaginal secretions provides the experimental basis for clinical diagnosis and treatment.

OBJECTIVETo evaluate the accuracy and utility of ultrasound-guided core needle biopsy (CNB) in the diagnoses of breast lesions.

METHODSThe clinical data of 2152 consecutive breast lesions examined by CNB were reviewed. The histological agreement between core pathology and subsequent excision pathology was studied. The benign diseases without repeat biopsy were followed up.

RESULTSThere were 1461 cancers in final diagnosis among 2152 breast lesions, 1339 cancers were diagnosed by CNB. The false-negative rate of CNB was 3.5% (51/1461), and the underestimation rate was 4.9% (71/1461). In the repeat biopsy, carcinoma was found in 17 (50.0%) of 34 atypical ductal hyperplasia lesions and 25 (46.3%) of 54 papillary lesions. In 1461 cancers, the false-negative rate of ultrasound-guided CNB (2.1%, 22/1068) was significantly lower than that of free-hand-guided CNB (7.4%, 29/393) (P < 0.05). The false-negative rate of two special doctors for CNB (1.2%, 8/681) was significantly lower than that of other doctors (5.5%, 43/780) (P < 0.05). In 738 of benign lesions, 417 cases were excised and 50 malignant lesions were found, 205 cases were followed up by 2 - 29 months (median, 10.2 months), and one malignant lesion was found.

CONCLUSIONSUltrasound-guided core needle biopsy with histopathological assessment is an accurate method in diagnosis of breast lesions. Excisional biopsy is required to the high-risk lesions in CNB.

OBJECTIVETo investigate the correlation of hypermethylation of BRCA1 and APC gene promoters with the response to anthracycline-based neoadjuvant chemotherapy in primary breast cancer.

METHODSOne hundred and forty patients with primary breast cancer received anthracycline-based neoadjuvant chemotherapy, and pretreatment hypermethylation status of BRCA1 and APC genes promoters was detected by methylation-specific PCR.

RESULTSOf the 140 patients, 30 (21.4%) achieved pathological complete response (pCR), and methylation rates of BRCA1 and APC gene promoters were 21.4% (30/140) and 18.3% (24/131), respectively. Among the 110 patients with unmethylated BRCA1 gene, 28 (25.5%) achieved pCR, while in the 30 patients with methylated BRCA1 gene, only 2 (6.7%) had a pCR, with a significant difference between the two groups (chi(2) = 4.94, P = 0.026). However, no statistically significant correlation was found between the methylation of APC gene and pCR to neoadjuvant chemotherapy in this cohort of patients (P > 0.05).

CONCLUSIONPrimary breast cancer with an unmethylated BRCA1 gene is prone to achieve a pathological complete response to anthracycline-based neoadjuvant chemotherapy than those with a methylated BRCA1 gene. BRCA1 methylation status may be a useful predictor for anthracycline-based neoadjuvant chemotherapy in primary breast cancer patients.

OBJECTIVETo investigate the incidence and the gene mutation frequencies and patterns of β-thalassemia (β-Thal) in ethnic Han children in Chongqing city.

METHODA total of 1726 children were screened by using automatic hemocytic analyzer, cellulose acetate electrophoresis and fetal hemoglobin alkali denaturation test. Samples with mean corpuscular volume (MCV) < 80 fl, cell hemoglobin content (MCH) < 27 pg and hemoglobin A2 (HbA2) levels >3.3%, fetal hemoglobin (HbF) >2% for β-Thal screening indicators. The positive samples of screening indicators were detected and identified by PCR-reverse dot blot method for 18 common β-Thal mutations in Chinese populations, unknown mutations samples were subjected to DNA sequencing analysis of the β-globin gene.

RESULTTwenty-five cases of β-Thal carriers were observed from the 1726 samples, with 24 cases of β-Thal heterozygote and one case of double heterozygote. Therefore, the β-Thal carrier rate was 1.51%. After 1726 peripheral venous blood samples analyzed by hematological parameters, 164 positive cases of β-Thal screening indicators were found, with the positive rate being 9.50% (164/1726). A total of 6 different gene mutations were detected, the four most common mutations were as the following: CD41-42, IVS-II-654, CD17 and beta E. These four mutations as the major types in this area accounted for 88.00% of all the mutations. In addition, one rare mutation of 5 'UTR; + (43 -40) was found, and one case of the hemoglobin variant of Hb Zurich was reported in Chinese people for the first time.

CONCLUSIONChongqing is a high risk region of the β-Thal. Epidemiological Data from the research was useul for the genetic counseling and the prevention of β-Thal major.

OBJECTIVEThe goal of the study is to investigate the feasibility of breast-conserving therapy for early primary breast carcinoma centrally located in the breast.

METHODS157 patients with stage I or II primary breast cancer located in the central part of the breast were operated with extended local excision and axillary lymph node dissection. Nipple-areola complex was excised in 18 patients. Ninety-three patients received two to six cycles neo-adjuvant chemotherapy. Radiotherapy was given postoperatively to the whole remaining breast.

RESULTSThe clinical response rate was 87.1% (81/93) and pathologic complete remission rate was 15.1% (14/93) after neo-adjuvant chemotherapy. Breast conservation surgery was performed successfully for all the patients in this series. After a median follow-up of 23 months (range 6-53 months), there was no recurrence in the ipsilateral breast. The aesthetic effect of the conserved breast was satisfactory including excellent for 88 patients and good for 48 patients representing of 86.6% of all cases.

CONCLUSIONBreast conserving surgery is suitable for the early centrally located primary breast carcinoma. Though the short-term results are satisfactory, the long-term follow-up is still needed for the final outcome.
