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.

Recently,more and more researches focus on the relationship between bone marrow fat and osteoporosis.From a pathological point of view, osteoporosis is traditionally regarded as the dysfunction of osteoblastic bone formation and osteoclastic bone resorption.Actually, bone marrow adipose tissue that constitutes a large proportion of bone marrow cells is indispensable for the balance of bone metabolism.Bone marrow fat, which is abundant in yellow bone marrow, increases gradually with aging.Bone marrow adipocytes and osteoblasts differentiate from a common progenitor, bone marrow mesenchymal stem cells(BMSCs).It is generally acknowledged that they are reciprocal repellent in the process of BMSC differentiation.Exploring the association between bone marrow adipocytes and osteoporosis is critical for better understanding its role in the pathogenesis and the future treatment of osteoporosis.In this review, we summary the recent progress in the association between bone marrow adipocytes and osteoporosis.

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 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.

Objective To investigate the cognition and treatment rate of hormone replacement therapy (HRT)in perimenopause women.Methods A survey was conducted in 262 perimenopause women first coming to outpatients care.A predesigned structured questionnaire was used to collect information:the symptoms of perimenopa-use women,the cognition and acceptance to the treatment.Results Finally,248 women with the mean age of (50.30 ±2.10)years finished the questionnaire,the natural menopause age was (48.90 ±1.90)years.48.79% of these women understood the role of HRT in clinical application,and only 12.50% knew the side effect of HRT. Among them,35.48% thought that HRT was necessary for the duration of perimenopause.40.73% of them had the attitude to treatment with HRT.After the education of perimenopausal acknowledgement,117 patients (47.18%) accepted the treatment with HRT.Conclusion It showed that the awareness and treatment rate of HRT in perimeno-pause women was low.The health education should be strengthened to improve the level of perimenopause health care.
