Objective To observe the insulin resistance in pregnant patients with chronic hepatitis C.Methods 87 pregnant patients with chronic hepatitis C were chosen as observation group,while 80 healthy pregnant women were chosen as control group.The fasting blood glucose(FPG),fasting insulin(FINS) and insulin resistance index (IRS) were detected and compared in the two groups.Results The FPG,FINS and IRS of the observation group were (5.40 ± 1.01 ) mmol/L,( 69.43 ± 38.05 ) mU/L and ( 16.65 ± 12.29 ),respectively,which were significantly higher than those of the control group [ (4.53 ± 0.56 ) mmol/L,(50.54 ± 20.07 ) mU/L and ( 10.17 ± 4.66) ],respectively(t =3.26,3.87,4.01,all P＜0.05).Conclusion There was significant insulin resistance in pregnant patients with chronic hepatitis C.

Triple-negative breast cancer ( TNBC ) is a subtype of breast cancer,and it is characterized by an aggressive clinical course with a poor prognosis.Treatment for TNBC has attracted much attention in recent years,however,there is no standard treatment for TNBC in clinical setting.The pCR rates of neoadjuvant chemotherapy in TNBC ranges from 12％ to 48％ in the current published data,and it is higher than that in other types of breast cancer,however,the fluctuating range of the TNBC ’s pCR is large in literature.Although the administration of adjuvant chemotherapy for early TNBC is controversial,the regimen without anthracyclines is reported to be suitable for early TNBC patients.Standard cytotoxic agents including taxanes and anthracyclines are still the main choices for TNBC salvage treatment,and the combination with gemcitabine or capecitabine may improve the overall survival.Poly (ADP-ribose) polymerase (PARP) is a new molecular target for TNBC in ongoing studies.Further research on the target-inhibitors such as BSI-201and Olaparib will provide more effective choices to clinical treatment.

The present preliminary study was to observe the feasibility of the use of polylactic acid gel (PLA-G) in modified radical mastectomy and the ability of the PLA-G in the prevention of flap adhesion after operation. Sixty-eight patients were diagnosed with breast cancer, and received modified radical mastectomy from Jan. 2004 to Dec. 2006. The patients were divided randomly into a treatment group and a control group (with 34 cases each). The PLA-G was used under the surface of the auxiliary operative wound in the treatment group, and nothing was used in the control group. The wound healing, the wound complication, the amount of drainage solution, the indwelling time of the drainage tube and the auxiliary skin adhesion were evaluated after operation in both groups. There were no statistical difference on wound healing between the first intension (29:27) and the second intention (5:7), and the wound dehiscence after taking the stitches out (0:0) between the two intensions, the hematoma (0:1) and the effusion of the wound (5:6), and the flap necrosis (1:2) between two groups. There were also no statistical difference on the amount of drainage solution per day (6 +/- 3) and indwelling time of the drainage tube (6 +/- 4) after operation between the two groups (P > 0.5). After the operation, the case load with no flap adhesion in the treatment group was significant higher compared with the control group (22:8). The case load with complete acquired skin flap adhesion in the treatment group was visibly lower than in the control group (3:19), which proved that there was a significant statistical difference between the two groups (P < 0.05). This study suggested that the using of PLA-G in the breast cancer modified radical mastectomy could prevent skin flap adhesion without any harmful effects in the wound healing.

Prolactin-inducible protein(PIP)is regarded as a kind of specific tumor marker,and detecting the expression of PIP from breast cancer tissues,metastatic lymph nodes and peripheral blood can find breast cancer micro-metastasis effectively.Some technologies such as immunohistochemistry,reverse transcription polymerase chain reaction and so on can detect PIP sensitivily.Recently,these technologies have been used in some clinical and basic studies.Detection rate of breast cancer micro-metastasis is improved effectively when PIP is combined with other tumor makers,especially mammag-lobin and cytokeratin 19.

Objective:To obtain apoptin gene and to induce tumor cell (HeLa) apoptosis. Methods:Apoptin gene was amplified by PCR from CAV TK5803 genomic DNA,and was then cloned into pCDNA3.1/His/Topo vector. After confirming by DNA sequencing, apoptin gene was subcloned into pCIneo vector.Recombinant plasmid pCDNA3.1/His/Topo-apoptin and pCIneo-apoptin were transformed into HeLa cells by Lipofectamine reagent. Three days after transfection,the HeLa cell was stained by Honchest 33258 and apoptosis was analysed by fluorescence microscope. Results and Conclusions: The full-length apoptin gene was cloned by PCR and inserted into pCDNA3.1/His/Topo vector. Sequence analysis demonstrated that it was same as published apoptin gene sequence. Three days after transfection, HeLa cell turned into apoptosis.

Objective To studythe effect of CD+4CD+25 regulatory T(Tr)cells on dendric cells(DC)in peripheral blood and deciduas from unexplained recurrent spontaneous abortion(URSA)patients.Methods Four URSA patients(abortion group)and 4 normal early pregnant women(control group)were enrolled in this study.Tr cells and DC in the peripheral blood and deciduas were isolated using Ficoll density gradient centrifugation and magnetic cell sorting(MACS).DC were cultured alone(DC alone)or in combination with Tr cells(DC+Tr)for 6 days,during which the release of interferon(IFN)-γandinterleukin(IL)-10 in the medium was subsequently measured by enzyme linked immunoadsorbent assay (ELISA).Results(1) Peripheral blood:there was no significant difference in IFN-γlevel between DCalone(23.2±0.7)ng/L and DC+Tr(22.5±3.0)ng/L in abortion group(P>0.05).The similar level of IL-10 was observed between DC alone(37±7)ng/L and DC+Tr(35±4)ng/L in abortion group(P>0.05).IL-10 level,but not IFN-γ,was significantly hisber in DC alone(54±20)ns/L than that in DC+ Tr(36±9)ng/L in control group(P<0.01).(2)Deciduas:there was no significant difference in IFN-γlevel between DC alone(23.4±2.6)ng/L and DC+Tr(24.4±2.5)ng/L in abortion group(P>0.05).Moreover,Similar IL-10 level was found between DC alone(28±7)ng/L and DC+Tr(25±5)ng/L in abortion group(P>0.05).IFN-γlevel in CD alone(30.7±4.6)ng/L was significantly higher than that in DC+Tr(22.6±3.8)ng/L in control group(P<0.01);whereas IL-10 level was much lower in DC alone (27±6)ng/L than that in DC+Tr(31±9)ng/L in control group(P<0.05).Conclusion The decreasing of immunosuppressive funetion of Tr eell of URSA patients affect its regulation on DC.resulting in imbalance of Th1/Th2 and abnormality of maternal-fetal jmmuno-tolerence in URSA.

Objective To investigate the feasibility and clinical effects of the pair ringer technology for bony avulsion of the posterior cruciate ligament under arthroscopy. Methods From January 2005 to July 2009, 23 patients were treated with the pair ringer technology for bony avulsion of the posterior cruciate ligament by arthroscopy. There were 15 male and 8 female, with an average of 39.3 years (ranging from 28 to 52 years). There were 4 cases of type Ⅱ, 14 type Ⅲ, and 5 type Ⅳ according to Meyer-Mckeever classification. The outcome measures were X-ray and MRI testing, Lysholm and Tegner knee function score. Results All the operations were finished in an hour. There were no complications as nerve injury or infection occurred in the study. The patients were followed-up for an average of 16.5 months (12-23 months). The Lysholm score rose from 50.3±6.1 preoperatively to 89.7±8.3 at the six months postoperatively (t=18.34, P=0.0007). The Tegner score rose from 1.7±0.5 preoperatively to 5.7±1.3 at the six months postoperatively (t=13.77,P=0.0008). All of the patients recover a functionally stable knee and have considerably improved knee function compared with their preoperative status. Conclusion The pair ringer technology under arthroscopy is a liable method for bony avulsion of the posterior cruciate ligament. This minimally invasive technology leads to rigid fixation, early rehabilitation.
