Objective To investigate the CT features of pulmonary sarcoidosis.Methods Ninety patients with histologically proved pulmonary sarcoidosis were retrospectively studied by using CT scans and clinical recording.Results The main CT findings of pulmonary sarcoidosis were nodules which were seen in 69 cases(76.7%),and the nodules mostly distributed around the bronchovascular bundle(n=37, 41.1%).Other abnormalities included consolidation(n=31,34.4%),ground-grass(n=39,43.3 %), thickening of bronchovascular bundle(n=30,33.3%),interlobular septal lines(n=58,64.4%), fibrosis(n=17,18.9%)including bronchial distortion(n=8,8.9%),linear shadow(n=5,5.6%), and honeycombing shadow(n=4,4.4%),air-trapping(n=3,5.3%),bronchial straitness(n=8, 8.9%),pleural thickening(n=42,46.7%),and hilar and mediastinal adenopathy(n=76,84.4%). Two or more abnormal findings co-existed in 83 cases.The pulmonary lesions co-existed with hilar and mediastinal adenopathy in 76 cases.The nodules(n=25),consolidation(n=9),ground-grass(n=11), thickening of bronehovascular bundle(n=10)were improved after therapy.Ten cases of the interlobular septal(10/22),0 of bronchial distortion(0/4),1 case of diffuse linear(1/3),and 0 case of honeycombing(0/2)were improved.Conclusion CT manifestations of pulmonary sarcoidosis are varied, but has some specific radiographic features.A correct diagnosis can be made.combined with hilar and mediastinal adenopathy.

The ingredients of five kinds of Zhejiang's yellow Chrysanthemum morifolium with different flower blossoming stages were comparatively analyzed. Polysaccharides, total flavonoids, volatile oil, alcohol extract, water extract, chlorogenic acid, luteolin, 3,5-O-dicaffeoyl quinic acid and fingerprint of the ingredient were determined as indicators. During flower blossoming stages, the ingredients of Ch. morifolium showed a big difference with a certain variation. At the early opening stage, the contents of flavonoids and volatile oil were higher, the content of chlorogenic acid, luteolin, 3,5-O-dicaffeoyl quinic acid were higher in the middle of the flowers 50% -80% fowers blossoming degree is the optimal time for harvest.

Objective To analyse the effects of serum estradiol levels during controlled ovarian hyperstimulation (COH) on the outcomes of in vitro fertilization and embryo transfer (IVF-ET). Methods The clinical data of 472 patients undergoing IVF-ET with GnRH analogues recombinant FSH long protocol were retrospectively analysed. The area under the curve (AUC) of estradiol (E2) level was calculated during COH, and patients were categorized into groups according to the percentile of AUC of E2(AUCE2) during COH. The general characteristics and parameters related to the outcomes of IVF-ET were compared among groups. Results The 10th percentile and 90th percentile of AUCE2 were 3 347.0 pmoL/L and 14 414.3 pmol/L, respectively. Four hundred and seventy-two patients were divided into lower reaction group (AUCE2 3 347.0 pmol/L, n=48), normal reaction group (14 414.3 pmol/L>AUCE2 > 3 347.0 pmol/L, n=376) and higher reaction group (AUCE2≥14 413.3 pmol/L, n=48). There was no significant difference in age, body mass index, baseline follicle stimulating hormone level, time of treatment with gonadotropin, endometrium thickness on day of transfer and embryos transferred(P>0.05). Compared with lower reaction group and normal reaction group, the number of oocytes per retrieval and number of embryos frozen were significantly larger(P<0.01) and the mild/severe ovarian hyperstimulation syndrome rate was significantly higher in higher reaction group(P<0.05). There was no significant difference in fertilization rate, cumulative embryo score, high-grade embryo rate, clinical pregnancy rate and implantation rate among groups (P> 0.05). Conclusion Sustained snpraphysiological serum E2 levels during the COH process do not adversely affect the quality of oocytes and embryos, clinical pregnancy rate and implantation rate to some extent in IVF-ET.

In this study, the psbA-trnH sequence as DNA barcode was used to evaluate the accuracy and stability for identification pteridophyte medicinal material Pyrrosiae Foliumas from adulterants. Genomic DNA from 106 samples were extracted successfully. The Kimura 2-Parameter (K2P) distances and ML tree were calculated using software MEGA 6.0. The intra-specific genetic distances of 3 original plants were lower than inter-specific genetic distances of adulterants. The ML tree indicated that Pyrrosiae Folium can be distinguished from its adulterants obviously. Therefore, the psbA-trnH sequence as a barcode of the pteridophyte, can accurately and stably distinguish Pyrrosiae Folium from its adulterants.

In order to identify Cimicifugae Rhizoma from its adulterants and to ensure its safe use, the internal transcribed spacer 2 (ITS2) sequence of Cimicifugae Rhizoma and its adulterants were amplified and bidirectionally sequenced by DNA barcoding technology. Sequence assembly and consensus sequence generation were performed by the CodonCode Aligner V3.7.1. The genetic distances were computed by MEGA 5.0. Identification analyses were performed using neighbor-joining (NJ) methods. The length of ITS2 sequence of the three origin plants of Cimicifugae Rhizoma include Cimicifuga heracleifolia, C. foetida, C. dahurica was 217, 219 and 219 bp, respectively. Their intraspecific genetic distance was much lower than the interspecific genetic distance with their closely related species. The NJ tree of ITS2 indicated that the three origin plants of Cimicifugae Rhizoma formed a monophyletic clade, Cimicifugae Rhizoma and its adulterants could be distinguished clearly. The authors proposed that ITS2 sequence was suitable for the authentication of Cimicifugae Rhizoma and its adulterants.
