Edema, as one of common clinical diseases, could be treated by taking medicines and adopting external therapies with traditional Chinese medicines (TCM). In recent years, there have been many clinical and basic studies concerning external therapies with TCM on edema Data showed that the external therapies are mostly composed of such purgating drugs as Rhei Radix et Rhizoma, Natrii Sulfas and Pharbitidis Semen, heat-clearing drug such as Phellodendri Chinensis Cortex and resuscitation-inducing drug such as Borneolum Syntheticum. The study showed that ingredients of external therapies did not pass through hilum and hepatic system, and thus avoided the first pass effect of livers. They enabled effective components of drugs to be rapidly absorbed through pores and skins, strengthened the effect against edema, shortened the treatment course, decreased side effects, and were convenient and inexpensive. External therapies with TCM could play unique advantages in inhibiting edema in the future clinical studies.

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.

Objective To investigate the possibility of detection of the human papillomavirus (HPV)L1 capsid protein to predict the coarse of mild or moderate cervical intraepithelial neoplasia(CIN).Methods Immunocytochemical analysis using antibody against HPV L1 capsid protein was carried out on 274 samples obtained from women performed Tri Path Pap tests.positive for high-risk HPV DNA detected by hybrid capture Ⅱ (HC-Ⅱ)or cytologic diagnosed atypical squamous cells of undetermined significance (ASCUS)or more severe.For cytological diagnosed,there were ASCUS 105 cases,low-grade squamous intraepithelial lesions (LSIL) 119 cases,atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H)9 cases,high-grade squamous intraepithelial lesions(HSIL)36 cases,and squamous cell carcinoma(SCC)5 cases.But for the pathologic diagnosed,there were chronic cervicitis 96 cases.CIN Ⅰ 55 cases,CIN Ⅱ 55 cases,CIN Ⅲ 32 cases,and SCC 6 cases.Results Of the 274 cases,HPV L1 capsid protein was positive in 69.8%(67/96) of cervicitis,83.5%(71/85)of CIN Ⅰ,41.8% (23/55)of CIN Ⅱ,3.1%(1/32)of CIN Ⅲ and 0(0/6)of SCC.Cytologic diagnosis revealed a higher expression rate in LSIL(75.6%.90/119) than that in ASCUS(63.8%,67/105)or in HSIL + SCC (9.8%,4/41;all P<0.01).Of 71 cases with ASCUS and ISIL without treated,none of HPV L1 positive cases(0/55)progressed in cytology,while 19%(3/16)of HPV L1 negative cases progressed to ASC-H,HSIL(P<0.01).Conclusion The expression rates of HPV L1 protein in liquid-based cell specimen is decreased as the cytopathology diagnosis severe degree.which may imply the histopathology diagnosis of cervix,predict the progression of cervical lesion,and help to treat the cases with ASCUS and LSIL.

Objective To analyzes the CT manifestations of pulmonary Langerhans cell histiocytosis (PLCH). Methods CT features of 11 patients with PLCH proved pathologically were analyzed retrospectively. Results The main findings in 11 PLCHs were cysts and nodules. Two cases only had cysts,and 1 only had nodules, which most had cavitations. The other 8 cases showed cysts and nodules with 4 cases mainly manifested with cysts and nine mainly manifested with nodules. Two cases had pulmonary interstitial changes. One case only had cysts in the left upper lung field and 10 cases had lesions not only in the upper and middle but in the lower lung field, which 2 cases had more lesions in the lower and costophrenic angle field and 8 cases had less lesions in the costo-phrenic angle field. Three of these 8 cases had more lesions in the superior lobe and apical segment of lower lobe. Conclusion CT manifestations of PLCH are helpful for the early diagnosis.

AlM:To determine the changes of regional macular retinal thickness ( RT ) with spectral domain optical coherence tomography ( SD-OCT ) after successful pars plana vitrectomy ( PPV ) surgery with inner limiting membrane ( lLM ) peeling in patients with idiopathic macular hole.
METHODS:A non-randomized retrospective case study on 17 patients ( 17 eyes ) who were hospitalized between March 1, 2011 and June 30, 2013. All 17 eyes had been diagnosed with idiopathic macular hole and thereafter underwent 25G-PPV surgeries performed by the same surgeon with lLM peeling and short - term gas tamponade. ln the 6mo-plus follow-up after surgery, these eyes were found to have successful closure in the macular hole. The macular RT of the nine areas in the Early Treatment Diabetic Retinopathy Study was measured by SD-OCT. All patients were applied by SD-OCT with linear scan of the macular. At least four examinations on the operated eye were conducted in contrast to the other normal eye: before the surgery, 3~5wk after the surgery (stage A), 2~3mo after the surgery (stage B), and >6mo after the surgery (stage C).
RESULTS:ln stage A, the macular RT of operated eyes in the areas of C, lS, ll, lN, OS, Ol, ON (263. 00±39. 48, 313. 92±18. 35, 311. 00±18. 02, 335. 67±19. 91, 280. 83±33. 74, 269. 92 ± 23. 32, 307. 00 ± 28. 40 ) were significantly thicker than the corresponding areas of the normal fellow eyes (220. 51 ± 23. 94, 292. 08 ± 21. 93, 282. 50 ± 20. 30, 288. 33 ± 20. 76, 251. 25±17. 60, 247. 75±21. 48, 265. 17±24. 76ü m) (P<0. 01) with the exception of the lT (291. 58±18. 97, 280. 33± 20.82üm) and OT (250.83±21.21, 242.08±24.02üm) (P>0. 01). ln Stage B, the macular RT in the areas of ll, lN, OS (335.67±19.20,319.75±19.20, 273.50±16.89üm) were significantly thicker than the corresponding areas of the normal fellow eyes (286. 33±20. 46, 293. 42±17. 64, 252. 50± 16.32üm) (P<0. 01). However, the macular RT of the operated eyes in the areas of C, lS, lT, Ol and OT had no statistically significant difference compared with the corresponding areas of the normal fellow eyes (P> 0. 01). ln Stage C, the macular RT of operated eyes with the areas of lN (321. 17 ± 19. 71ü m) were significantly thicker than the corresponding areas of the normal fellow eyes (296.25±19.57üm) (P<0.01). Meanwhile the other areas of the operated eyes were not significantly different from the normal fellow eyes (P>0. 01). Moreover, the macular RT of operated eyes in the areas of ON, lT (307. 00±28. 40, 291. 58 ± 18. 97ü m ) in stage A significantly decreased compared to that of the corresponding areas in stage C (276. 08±32. 39, 278. 75±10. 19ü m) (P<0. 01).
CONCLUSlON: SD-OCT is a convenient tool for the observation of macular regional changes after macular hole surgery. Macular RT had persistent changes after vitrectomy on eyes with macular hole by SD-OCT. lLM peeling may have caused microstructural changes in wide areas of the macular region after PPV surgery. More support and evidence were provided to the further study of the long - term observation for the structural and function of macular after macular hole surgery.
