OBJECTIVE To explore the difference in chemical components of essential oil from medicinal part （rhizome）and non-medicinal parts （fibrous roots ，stems，and leaves ）of Atractylodes chinensis，and to preliminarily evaluate their antibacterial activity in vitro . METHODS The essential oil was extracted from three parts of A. chinensis by steam distillation ，and their chemical components and relative contents were analyzed and identified by gas chromatography -mass spectrometry （GC-MS）. The antibacterial activities of essential oil （5 mg/mL） from different parts against Staphylococcus aureus ，S. albus and Bacillus subtilis were determined by paper diffusion method . The correlation between chemical components in essential oil and antibacterial activity was analyzed . RESULTS A total of 60 chemical constituents were identified from the essential oilof rhizome ，fibrous roots ，stems and leaves of A. chinensis， mainly composed of terpenes ，sesquiterpenoids，alcohols and ketones. There were 8 kinds of common components in the essential oil of rhizome ，fibrous root and stem and leaves ，which were elementol ，cadinene，agarospirol，valencian citrine ， caryophyllin，β-sesquidiene，γ-eucalyptol and β-eucalyptol. A total of 26 components were identified from the essential oil of rhizome，of which the relative content of 4-benzaldehyde was the highest （31.56%）；a total of 21 components were identified from the essential oil of fibrous roots ，among which the relative content of β-eucalyptol was the highest （44.39%）；a total of 42 components were identified from the essential oil of stems and leaves ，among which the relative content of β-sesquidiene was the highest（14.83%）. The essential oil from different parts had certain antibacterial effect on S. aureus，S. albus and B. subtilis. The order of antibacterial effect was rhizome ＞fibrous roots ＞stem and leaves ；the relative contents of β-caryophyllene，α-humulene and modhephene were positively correlated with inhibitory effects of essential oil against S. aureus and B. subtilis（P＜0.05 or P＜0.01）. The relative contents of atractylone ，zingiberene and agarospirol were positively correlated with the inhibitory effect of essential oil against B. subtilis（P＜0.05 or P＜0.01）. CONCLUSIONS There are significant differences in the chemical composition and contents of essential oil from medicinal and non -medicinal parts of A. chinensis，and all of them have antibacterial activity in vitro .

The pathological hallmarks of psoriasis involve alterations in T cell genes associated with transcriptional levels, which are determined by chromatin accessibility. However, to what extent these alterations in T cell transcriptional levels recapitulate the epigenetic features of psoriasis remains unknown. Here, we systematically profiled chromatin accessibility on Th1, Th2, Th1-17, Th17, and Treg cells and found that chromatin remodeling contributes significantly to the pathogenesis of the disease. The chromatin remodeling tendency of different subtypes of Th cells were relatively consistent. Next, we profiled chromatin accessibility and transcriptional dynamics on memory Th/Treg cells. In the memory Th cells, 803 increased and 545 decreased chromatin-accessible regions were identified. In the memory Treg cells, 713 increased and 1206 decreased chromatin-accessible regions were identified. A total of 54 and 53 genes were differentially expressed in the peaks associated with the memory Th and Treg cells. FOSL1, SPI1, ATF3, NFKB1, RUNX, ETV4, ERG, FLI1, and ETC1 were identified as regulators in the development of psoriasis. The transcriptional regulatory network showed that NFKB1 and RELA were highly connected and central to the network. NFKB1 regulated the genes of CCL3, CXCL2, and IL1RN. Our results provided candidate transcription factors and a foundational framework of the regulomes of the disease.

Objective:To explore the correlation between prenatal clinical data with etiological diagnosis and neonatal outcome in isolated fetal ascites.Methods:Totally, 36 pregnancy cases diagnosed as isolated fetal ascites by ultrasound in Provincial Hospital Affiliated to Shandong University from June 22nd, 2016 to September 28th, 2018 were collected. Invasive prenatal diagnosis was performed by taking fetal cord blood, amniotic fluid, and fetal ascites respectively for cytogenetics, molecular genetics and biochemical examination and the impact of intrauterine therapeutic procedures on neonatal outcomes was evaluated as well. The correlation among prenatal examination, pathogeny and prognosis was analyzed by Fisher′s exact test.Results:(1) The prognosis of isolated fetal ascites initially presenting ≥28 weeks was better than that before 28 weeks, survival rate of 1-year-old were 13/15 and 9/17,respectively, the difference was statistically significant ( P<0.05). (2) The etiologic diagnosis rate of ascites before delivery was 31%(11/36), which increased to 53%(19/36) totally after birth. Characteristics of cases which were defined prenatally were as follows: 8 cases of digestive tract diseases showed ultrasonic abnormalities, including echogenic bowel, bowel dilatation and polyhydramnios; platelet level in umbilical cord blood of fetuses infected with cytomegalovirus were below 100 × 10 9/L in 2 cases; 1 case of urinary system malformation showed megalocystis and hydronephrosis. Cases which were defined causes after birth included: 3 fetuses with chyloperitonium presented persistent fetal ascites; 3 cases of digestive-related causes were rectal duplication with infection, mesentery stenosis, and intestinal atresia; other causes included Pierre-Robin syndrome and Budd-Chiari syndrome. (3) The live birth rate was 72% (26/36) and survival rate of 1-year-old was 61% (22/36). And 9/10 of infants who underwent surgeries got good outcomes. Fetal ascites due to abdominal or pelvic factors turned well in 13/16 of cases. Conclusions:The pregnancy outcome of fetal isolated ascites depends mainly on primary causes. Gastrointestinal abnormality is one of the most common causes. Excluded intrauterine infection, chromosomal abnormality and abnormal systemic ultrasonic findings, fetus with reduced ascites as the pregnancy progresses will get good outcome.

Objective To study the effect of age-related white matter changes (ARWMC) on first symptomatic ischemic stroke events in the oldsters. Methods For the prospective study, a total of 368 eligible oldsters were enrolled in the study from January 2010 to August 2012. The degrees of ARWMC were assessed by ARWMC scale;according to the scores, they were divided into non ARWMC group, mild-moderate ARWMC group and severe ARWMC group. The patients were followed up once every 3 months. The clinical endpoint events and time (first symptomatic ischemic stroke, myocardial infarction and all-cause death) were recorded. Analyses of variance and Chi-square test were used to compare the differences of clinical data among the 3 groups. COX regression was used to assess the risk differences of first symptomatic ischemic stroke in the oldsters of three groups. Results After an average of follow-up for 48.7 months, 50 participants (13.6％) had first symptomatic ischemic stroke;25 (25.8％) were categorized as the severe ARWMC group, 22 (10.9％) were as the mild-medium group, and 3 (4.4％) were as the non ARWMC group. Among the three groups, the differences in age, history of hypertension, systolic blood pressure, incidence of clinical endpoint events and first symptomatic ischemic stroke, and follow-up time of endpoint events were statistically significant (P<0.05); patients from the severe ARWMC group were the oldest, and had the longest history of hypertension, the highest systolic blood pressure, the highest incidence of clinical end events and first symptomatic ischemic stroke, and the shortest follow-up period for clinical end events. COX regression analysis showed that the risk of first symptomatic ischemic stroke in the severe ARWMC group was about 8 times higher than that in the non ARWMC group (hazard ratio=9.012, 95％CI: 2.310-35.154, P=0.002). Conclusion In oldsters, severe ARWMC often accompany hypertension history and poor blood pressure controll, and it is an independent and serious risk factor for long-term first symptomatic ischemic stroke.

Compare the two parts of volume of endometriosis,there was no statistically significant difference.Conclusion Using the lancet to establish the endometriosis model has a high success rate, and subcutaneous model is better than peritoneum.

BACKGROUNDWith the increasing popularity of cosmetic facial filler injections in recent years, more and more associated complications have been reported. However, the causative surgical procedures and preventative measures have not been studied well up to now. The aim of this stady was to investigate the clinical characteristics and visual prognosis of fundus artery occlusion resulting from cosmetic facial filler injections.

METHODSThirteen consecutive patients with fundus artery occlusion caused by facial filler injections were included. Main outcome measures were filler materials, injection sites, best-corrected visual acuity (BCVA), fundus fluorescein angiography, and associated ocular and systemic manifestations.

RESULTSEleven patients had ophthalmic artery occlusion (OAO) and one patient each had central retinal artery occlusion (CRAO) and anterior ischemic optic neuropathy (AION). Injected materials included autologous fat (seven cases), hyaluronic acid (five cases), and bone collagen (one case). Injection sites were the frontal area (five cases), periocular area (two cases), temple area (two cases), and nose area and nasal area (4 cases). Injected autologous fat was associated with worse final BCVA than hyaluronic acid. The BCVA of seven patients with autologous fat injection in frontal area and temple area was no light perception. Most of the patients with OAO had ocular pain, headache, ptosis, ophthalmoplegia, and no improvement in final BCVA.

CONCLUSIONSCosmetic facial injections can cause fundus artery occlusion. Autologous fat injection tends to be associated with painful blindness, ptosis, ophthalmoplegia, and poor visual outcomes. The prognosis is much worse with autologous fat injection than hyaluronic acid injection.

Objective To explore the effects of silver needle with systematical on shoulder-hand syndrome (SHS) after stroke. Methods 80 stroke patients with SHS were randomly divided into silver needle group (obsevation group) and body acupuncture group (control group) with 40 cases each group. Both groups received same rountine treatment and rehabilitation exercises after acupuncture. The color Doppler flow imaging (CDFI) was used to measure the velocity of blood flow of the upper limbs, and the Fugl-Meyer Assessment was used to assess motor function of the upper limbs after 3 weeks. Results There was no significant difference between 2 groups before and 1 months after treatment (P>0.05), but there was significant difference 3 and 6 months after treatment (P<0.01). The velocity of blood flow of ulnar artery,radial artery, ulnar veins, radial veins and middle finger digital artery were higher in the observation group than in the control group (P<0.01). Conclusion The silver needle combined with systematical rehabilitation can improve the velocity of blood flow of artery and veins of upper limb, and improve the motor function of upper limb.

ObjectiveTo investigate the efficacy of highly active antiretroviral therapy (HAART) for HIV/HCV co-infection patients. MethodsA randomized and double blinded trial was conducted in sixty-three HIV/HCV co-infected patients ( group A) and 62 HIV infected patients ( group B). The group A (study group) was further divided into A1, A2, A3 subgroups randomly by Spw-Pb network data system, and were given three different HAART regimens based on nevirapine (NVP), efavirenz (EFV) and lopinavir/ritonavir(LPV/r), respectively. CD4+ T lymphocyte counts, HIV virus load, glutamate-pyruvate transaminase (ALT) were detected at baseline and at the endpoint of study (48 weeks). SPSS 13.0 was used for statistical analysis. One-way ANOVA and LSD-t tests were performed. ResultsAfter 48 weeks treatment, HIV RNA became negative in 59 patients of group A (59/63, 93.7％ ), while that in group B was 61 (61/62, 98.4％ ) (x2 =0. 159, P ＞ 0.05 ). CD4+ T lymphocyte count in group A was (208 ± 77 )/μL, which was significantly lower than that in group B (263 ± 78)/μL (t =-2. 759, P = 0. 008 ).ALT level in group A was (57 ±49)U/L, which was significantly higher than in group B (31 ± 14) U/L (t = 2. 027, P = 0.047). CD4 + T lymphocyte count in group A3 was significantly higher than that in A1 (t=-2. 191, P =0.045), while ALT level in A1 was much higher than that in subgroups A2 and A3 ( t = 2.568 and 2.478, P ＜ 0. 05 ). The incurrence of drug-induced hepatitis in HIV/HCV co-infected group was much higher than that in HIV infected group (55.5％ vs. 27.4％, x2 = 10. 182, P = 0.001 ).ConclusionsHCV co-infection in HIV patients shows no impact on virological response to HAART, but the immunological response is poorer.Hepatotoxicity is common among patients receiving HAART, especially those who are receiving NVP containing regimens. LPV/r based regimens are recommend for HIV/HCV coinfected patients.
