ObjectiveTo investigate the prevention and management of the hemorrhage during laparoscopic cholecystectomy( LC), and improve success ratio. MethodsThe medical data of 420 cases with LC from May 2003 to 2009, September were analyzed retrospectively, including total number, hemorrhage site and ways of prevention and management. Results417 cases experienced successful C,with success ratio 99.3%. 49 cases ( 11.7% ) had hemorrhage, and in 46 cases(93. 9% ), it was stopped by laparoscope or hemostasis by compression,3 cases were rescued by operation. All hemorrhage sites included 15 cases(30. 6% ) in triangle de Calot,26 cases(53. 1% ) in gallbladder bed, and 8 cases ( 16.3% ) in incision. ConclusionA reliable opetration and appropriate hemostasis are critical of the successful operation and prevention of complications after LC.

Objective To evaluate the relationship between cranial CT characteristics and prognosis after first-ever primary supratentorial intracerebral hemorrhage (PSICH). Methods The data of clinic and CT in patients with first-ever PSICH were registered prospectively and followed up for 6 months. The relationship between the prognosis and the clinic data was analyzed using univariate and multivariate Logistical regression analysis.Results (1) The volume of hematoma was an independent CT predictor of death at 1st, 3rd and 6th month. (2) Both the volume of hematoma and secondary ventricular hemorrhage were independent CT predictors of death/disability at 6th month.Conclusions (1)The volume of hematoma can be used to predict death in patients with PSICH.(2)The volume of hematoma and secondary ventricular hemorrhage can be used to predict the death/disability rate of PSICH.

Objective To understand brucellosis infective status of Shapotou District, Zhongwei City of Ningxia. Methods The methods of stratified random sampling of epidemiological survey were used among high risk groups in 2008, who underwent erythromycin red plate cohesion test(RBDT) and test-tube agglutination test (SAT), in accordance with the diagnostic criteria for confirming cases of brucellosis(GB 15988-1995). Results Totally an occupational group of 2480 brucellosis in 10 townships were investigated, and 604 sera were tested. Tweenty eight cases were infected, the infective rate was 4.64%(28/604), 15 cases were diagnosed as brucellosis patients, prevalence rate was 2.48% (15/604); cattle attendants had the highest infection rate of 6.45% (26/403). Conclusions Brucellosis epidemic in Shapotou District, Zhongwei City of Ningxia, and it is place related to vocation.

Objective To evaluate the regulatory effect of hydroxychloroquine on in vitro differentiation of regulatory T cells(Treg). Methods Fifteen milliliters of peripheral blood were obtained from a healthy human subject followed by isolation of monouclear cells and sorting of naive T cells. Then, the naive T cells were classified into two groups:control group cultured with the presence of tumor growth factor(TGF)?βand interleukin(IL)?2, experimental group cultured with the presence of 20μmol/L hydroxychloroquine and inducing factors. The number and percentage of CD4+Foxp3+Treg cells were determined by flow cytometry at days 0, 6, and 12. Results The number of Treg cells at days 0, 6, and 12 were(2 ± 0.4)× 104,(13.2 ± 5.2)× 104, and(143.5 ± 35.9)× 104 respectively in the control group, (2 ± 0.5)× 104,(2.4 ± 0.4)× 104, and(5.6 ± 3.5)× 104 respectively in the experimental group. There was a significant difference in the number of CD4+Foxp3+ Treg cells between the two groups at days 6 and 12 (t = 3.78 and 6.16, respectively, both P < 0.05). At day 12, the percentage of CD4 +Foxp3 + Treg cells was 79.7% ± 18.1% in the experimental group, compared to 16%± 13%in the control group(t=11.77, P<0.01). Conclusion Hydroxychloro?quine could inhibit the differentiation and proliferation of CD4+Foxp3+Treg cells in vitro.

Objective To analyse the mutation of low density lipeprotein receptor (LDLR) gene associated with familial hypercholesterolemia (FH) and make a discussion on the relationship between genotype and phenotype. Methods The blood fat, electrocardiogram, heart and great vessels color Doppler were examined in propositus and family member. The promoter and all eighteen exons of LDLR gene were investigated by polymerase chain reaction (PCR),degenerate high performance liquid chromatogram (DHPLC) and DNA sequence analysis. The results were compared with the normal sequences in GenBank and FH database (www.ucl.uk/fh) to find the mutation. In addition,the apolipoprotein B100(ApoB100) gene for the known mutations(Q3500R) that cause familial defective ApoB100(FDB) was detected by directed screening.Results Two novel heterozygous c.1864 G→A (Asp622Asn) and c.1959 C→T(Val 653Val) mutations in the exon 13 of LDLR in promoter were detected. And Asp622Asn mutation segregated with the disease. No mutation Q3500R of ApeB100 was observed. Conclusions The heterozygous c.1864 G→A (Asp622Asn)mutation of LDLR gene is firstly determined in China. The heterozygous c.1864 G→A (Asp622Asn)mutation of LDLR gene is probably responsible for FH. Perhaps it is a particular pathogenesis for Chinese people. PCB-DHPLC could be used for detecting the mutation.

Objective To investigate the expression and significance of the human telomeruse gene (hTERC)in the cytologic specimens of cervix for early cervical lesion screening.Methods Cytologic samples of cervix including 120 normal persons,86 CIN patients and 14 SCC patients were analyzed for aberrations of 3q26 using a commercially available two-color FISH probe.Results Positive expression rates of hTERC gene in normal,CIN Ⅰ ,CIN Ⅱ,CIN Ⅲ and SCC samples were 1.7%(2/120),2.6%(1/38),55.6%(10/118),87.5%(14/16),100.0%(14/14),100.0%(14/14),respectively.Compared with CIN Ⅰ/CIN Ⅱ group,hTERC gene positive expressions in SCC/CIN Ⅲ group were higher significantly(P=0.01),and them were also difference between CIN Ⅰ-CIN Ⅲ group and normal controls(X~2=113.52,P ＜0.01).With progression from CIN to carcinoma,polyploidization resulting in aneuploidy and high TERC gene copy numbers in SCC group ascended significantly.Among the total abnormal cells,the number of the cells percentage which hTERC amplification signals was more than 3:3 in CIN Ⅰ ,CIN Ⅱ,CIN Ⅲ and SCC groups were 6.12%,7.98%,28.07% and 33.97%,respectively.Condusion The hTERC gene is increasingly gained with progression of CIN and may appear to be another screening testmarker for early cervical cancer screening and accessory diagnosis.

OBJECTIVE:To study the absorptive characteristics of ginsenoside Rb3 in Caco-2 cell monolayer model. METHO-DS:The ginsenoside Rb3 cell samples underwent high speed centrifugation, then the supernatant was collected and determined by LC-ESI-MS/MS method in which the mobile phase consisted of acetonitrile-1 mmol?L-1 ammonium formate water solution (34 ∶ 66) with ginsenoside Rg2 as internal standard, and the tandem mass spectrometry was operated in negative electrospray ionization in a multiple reaction monitoring (MRM) mode, with detection ions m/z1077.7→m/z 783.4 for ginsenoside Rb3 and m/z 783.6→m/z 475.1 for ginsenoside Rg2.The concentration of ginsenoside Rb3 across the Caco-2 cell monolayer model was determined and the apparent permeability coefficient(Papp) of ginsenoside Rb3 was calculated. RESULTS: The calibration curve for ginsenoside Rb3 was linear in the range of 50～2 000 ng?mL-1,with intra-day precision and inter-day precision at less than 15%. P(AP-BL) from apical side (AP) to basolateral side (BL) was 3.22?10-6 cm?s-1, whereas P(BL-AP) from BL to AP was 6.0?10-6 cm?s-1,and the ratio of P(BL-AP)/P(AP-BL) was 1.86.CONCLUSION:The LC-ESI/MS/MS method is simple and sensitive, and it is applicable for the study of the absorptive characteristics of ginsenoside Rb3 in Caco-2 cell monolayer model.
