OBJECTIVETo observe the effect of Cangfu Congxian Decoction (CCD) on oxidative stress in granulosa cells of polycystic ovary syndrome (PCOS) patients.

METHODSForty PCOS patients underwent in vitro fertilization-embryo transfer (IVF-ET) were assigned to the treatment group and the control group 1 according to random digit table, 20 in each group. Patients in the treatment group took CCD (200 mL, once in the morning and once in the afternoon) 2 months before IVF-ET, while those in the control group 1 took no Chinese medical decoction. Recruited were another 20 patients undergoing IVF-ET for tubal factors (as the control group 2). The clinical effect of IVF-ET were observed, including oocyte retrieval number, 2 pronuclear (2PN) fertilization rate, good quality embryo rate, clinical pregnancy rate, and ovarian hyperstimulation syndrome (OHSS) induced transplantation cancel rate. The expression of relative oxygen species (ROS) in granulosa cells was detected using cell immunofluorescence combined with confocal microscopy and FCM.

RESULTSCompared with the control group 1, occyte retrieval number, 2PN fertilization rate, and good quality embryo rate increased in the control group 2 and the treatment group (P <0. 05). OHSS induced transplantation cancel rate decreased in the control group 2 (P < 0.05). Fluorescence intensity of ROS decreased in the treatment group and the control group 2, as compared with the control group 1 (P < 0.01).

CONCLUSIONCCD increased good quality embryo rate by down-regulating the expression of ROS protein in ovarian granulosa cells, and correcting in vivo oxidative stress.

OBJECTIVETo study the effects of kneepad on expression of Bcl-2 and p53 mRNA of chondrocyte in white rabbits with knee osteoarthritis, so as to explore and treatment mechanism of OA kneepad on apoptosis of chondrocytes of rabbits with knee osteoarthritis in molecular degree.

METHODSForty-four Japanese healthy 6-month-old rabbits (equal male and female,the weight ranging from 2 to 2.2 kg) were used to establish knee osteoarthritis models by modified Hulth method. The rabbits were randomly divided into 6 groups: normal group, model group, control group (microwave), experimental group 1 (electricity), experimental group 2 (thermal), experimental group 3 (kneepad). Ten rabbits in the normal group were breed with conventional method; 9 rabbits in the model group were breed with conventional method after model made; 9 rabbits in the control group were treated with microwave for 30 minutes, one time daily; 9 rabbits in the experimental group 1 were treated with electricity (density wave) for 30 minutes,one time daily;8 rabbits in the experimental group 2 were treated with hot (hot soft membrane) for 30 minutes, one time daily; 9 rabbits in the experiment group 3 were treated with electrothermal (OA knee pad) for 30 minutes, one time daily. All the rabbits were treated for 16 weeks and then sacrificed. The expressions of Bcl-2 and p53 mRNA of chondrocytes in knee joint were detected by using fluorescence quantitative RT-PCR method.

RESULTSAt the 16 hthek,th e OD260/OD280 value range of total RNA extracted from rabbit articular cartilage tissue in each group were all at 1.80 to 2.00,wh ich indicates high RNA purity. The p53 relative mRNA in articular cartilage cells of model group,th e control group,th e experimental group 1 ,r oup 2,gr oup 3 were overexpressed,an d Belc2 mRNA expression levels of articular cartilage cells were low expression,an d compared with the normal group there were significant differences (P < 0.01). Belc2, p53 mRNA expression in articular cartilage cells,th ere were significant differences (P < 0.01) between the control group, experimental group 1, group 2, group 3 and model group. The results between the control group, experimental group 1 ,group 2 and group 3 had significant differences (P < 0.01).

OBJECTIVETo investigate the efficacy, indication, advantage and disadvantage of methods for reduction mammaplasty.

METHODSThirty one cases with breast hypertrophy received reduction mammaplasty using various incisions and pedicles. Based on the follow-up of the cases, the appearance, nipple-areola complex sensory function and scars were evaluated.

RESULTSAmong the skin incision pattern, inverted T, short-horizontal invert T and vertical incision got excellent breast contour (100%), otherwise, periareolar incision got the less scar (100%). The postoperative result of lateral pedicle, lateral inferior pedicle and mammary gland pedicle were satisfactory in terms of the nipple-areola sensation and the amount of mammary tissue removed.

CONCLUSIONSBreast contour and scar formation postoperative are related to incision design, Invert T incision or short-horizontal invert T incision is a good alternative to moderate and large hypertrophies, Periareolar incision is suitable to small hypertrophies. There is a relationship existing between pedicle location and retention of sensation or amount of mammary tissue removed. The inferior pedicle and lateral-inferior pedicle allows better shaping as well as maintaining good sensation.

This paper is in order to discussion with the composition and characteristics of Tibetan medicine plant resources, and promote the reasonable protection and utilization of the resources of Tibetan materia medica. Statistical analysis of species, distributions, and others of Chinese endemic seed plant from Tibetan medicine plants and usually used in the clinic of Tibetan medicine. The results showed that there are 523 species (25%) of Chinese endemic seed plant, belonging to 65 families and 162 genera, in about 2 000 varieties of Tibetan medicine plants recorded in relevant literatures. There are 180 Chinese endemic seed plant species (28%) belonging to 42 families and 72 genera from 625 medicine plants usually used in the clinic of Tibetan medicine. Specifically, the most of these Chinese endemic seed plant species are characteristic crude drug used in Tibetan medicine, and mainly or only distributed in Qinghai-Tibet Plateau. And a few species of them were intersected with traditional Chinese medicines (TCM) and other ethnic medicines. In addition, about 10% are listed in China Species Red List. The Qinghai-Tibet Plateau is the most abundant areas of Areal-types of the Chinese endemic seed plant. This is the biological and ecological reason formation the characteristics of Tibetan medicine plant resources. Therefore, strengthen the research of Chinese endemic seed plants used in Tibetan medicine is great significance for the reasonable protection and utilization of Tibetan medicine plant resources.

OBJECTIVETo study the clinicopathologic features of pure mucinous carcinomas of the breast with diffuse micropapillary pattern.

METHODSTwenty-six cases of micropapillary variant of pure mucinous carcinoma of the breast were retrospectively reviewed by light microscopy, immunohistochemistry and clinical data analyses.

RESULTSThe age of 26 female patients ranged from 30 to 77 years old, of which 12 cases with clinical details available were mean 54 years old. The tumor diameter ranged from 0.8 to 9.0 cm (mean 3.2 cm). Ipsilateral axillary nodal metastases were identified in 3 cases. Cutaneous involvement was also found in 2 cases. The tumor cells showed the similar architectural arrangement as in invasive micropapillary carcinoma, with peripheral borders of the cell clusters highlighted by epithelial membrane antigen. Various amount of mucin occupied the retraction spaces around the tumor cells. Compared with conventional pure mucinous carcinoma of the breast, mucinous carcinomas with micropapillary pattern showed different nuclear grades (19 cases of grade I, 2 cases of grade II, 5 cases of grade III). The micropapillary cell clusters varied in size (22 cases of big micropapillary and 4 cases of small). Intraductal carcinoma was observed in 12 cases. Calcification and psammoma bodies were observed in 8 cases. Immunophenotyping, the tumor cells were with higher expression of hormone receptors, but HER2 were negative. Ki-67 positive index was 1% ∼ 70%. Neuroendocrine differentiation was observed in 6 cases.

CONCLUSIONSThe micropapillary variant of pure mucinous carcinoma of the breast, which mainly occurs in younger women, may carry the similar propensity for angioinvasion and nodal metastasis as infiltrating micropapillary carcinoma at least in cases with high nuclear grade. This morphologic subtype needs to be distinguished from conventional pure mucinous carcinoma of the breast and treated properly.

OBJECTIVETo introduce the clinical experience of nipple-areolar reconstruction with the modified arrow flap.

METHODSThe arrow flaps were modified for nipple-areolar reconstruction in 12 cases. Among them, 2 cases were treated with combined thin split-thickness skin graft; 4 cases with autologous rib implant and tattoo; 6 cases with tattoo.

RESULTSAll the reconstructed nipples were survived. The reconstructed nipples lost projection 1 month after operation in 2 cases. The other 10 cases retained 50% of the nipple projection 3 months after operation. The results were maintained with satisfactory symmetry during the follow-up period of 6 months to one year.

CONCLUSIONSThe modified flap is easily performed with reasonable design and no need of donor site. The nipple projection can be maintained with good long-term effect.

BACKGROUNDPulmonary capillary hemangiomatosis (PCH) is a rare disease and no Chinese case has been reported yet. The disease is often misdiagnosed and its clinical characteristics are incompletely described. The aim of this study was to describe two Chinese cases and to clarify the clinical and radiographic parameters of patients with PCH.

METHODSTwo PCH cases were presented and other cases were searched from the English literature. All available clinical and radiographic data were collected from 62 literature reported PCH cases. A pooled analysis of total 64 cases was made.

RESULTSDyspnea and hemoptysis were the most common clinical symptoms of PCH. Pulmonary hypertension (PH) was found in 78% of the reported cases. PCH typically showed characteristic diffuse or patchy ground-glass opacities (GGOs) and/or multiple ill-defined centrilobular nodules in the computed tomography.

CONCLUSIONSThe diagnosis of PCH requires a high clinical suspicion. However, both clinical presentations and radiographic studies often provide clues to the diagnosis, which may prompt early lung biopsy for a definite diagnosis.
