Orychophragmus violaceus and/or chicory forage affects performance, egg quality, sensory evaluation and antioxidative properties in native laying hens.

Orychophragmus violaceus (OV) and chicory (Cichorium intybus L., CC) can be used as fresh or dry forage for animals. To determine whether OV and/or CC have beneficial effects on performance and egg quality, a total of 1212 28-wk-old Beijing You Chicken (BYC) laying hens with similar performance were randomly allocated to 4 groups with 3 replicate pens per group, and 101 birds per pen. The birds were fed a basal diet (control), the basal diet + OV (3.507 kg/d/pen), the basal diet + CC (2.525 kg/d/pen), and the basal diet + OV + CC (OVC, 1.7535 kg/d/pen OV + 1.2625 kg/d/pen CC) for 3 wks after one wk of adaptation. The results showed that egg-laying rate was not affected by OV, CC and OVC (p > 0.05), but weekly average egg mass was significantly increased by OV and CC (p < 0.05). The feed egg ratio in the CC group (2.82) was significantly lower than that in the other three groups (p < 0.05). The eggshell thickness (EST), albumen height (AH) and Haugh unit (HU) were decreased by OV and CC (p < 0.05); while yolk color (YC) was increased in the CC and OVC groups (p < 0.05). Egg grade was decreased by OV (p < 0.05). Sensory evaluation showed that there was a trend for increased YC in OV, CC and OVC (p = 0.089). Serum total protein was significantly lower in OV group than those in the control and CC group (p < 0.05); serum albumin content was significantly decreased in OV, CC and OVC groups (p = 0.006). Serum glutathione peroxidase activity in CC and OVC groups was significantly higher than that in the control group (p < 0.05). In conclusion, the present study suggests that CC had a better effect on the performance of the native laying hens than OV. The OV and CC affected egg quality, while YC was increased in CC and OVC groups. The OVC improved YC and serum antioxidative properties of native laying hens without affecting the performance.

[The association between frontotemporal connecting fibers and seizure severity in patients with temporal lobe epilepsy].

The patients with temporal lobe epilepsy (TLE) admitted in the Department of Neurology, Zhongshan Hospital, Fudan University from June 2009 to February 2012 were prospectively enrolled. The diffusion tensor imaing was performed on the patients at the time of enrollment and 3 years later. The fractional anisotropy (FA) values of the white matter connecting fibers(bilateral hooked, arcuate, cingulate, and superior longitudinal tracts), the connecting fibers of both hemispheres(anterior union, anterior callosal forceps, posterior forceps, and bilateral fornix), and fibers of perirhinal cortices system(bilateral radiating crown and anterior limb of the internal capsule) were measured by the region of interest method. The severity of epilepsy was evaluated using the Veterans Administration Seizure Type and Frequency Rating Scale(VA-2) and National Hospital Seizure Severity Scale (NHS3). A total of 51 patients with TLE were screened, with 27 patients completing the 3-year follow-up. There were 13 males and 14 females with an age of (32±11) years and a follow-up duration of (39.1±1.1) months. During the follow-up, 6 patients had increased/unchanged NHS3 or VA-2 scores, while 21 patients had decreased scores. Three years later, the FA values of the bilateral arcuate fasciculus, the right superior longitudinal fasciculus, the right radial coronal and corpus callosum anterior forceps in TLE patients decreased compared to baseline(P<0.05). However, compared to the patients with decreased VA-2 scores during the follow-up, the degree of increase in FA values (ΔFA, follow-up FA value-baseline FA value) of the ipsilateral hook bundle caused by epilepsy was more significant in the group with increased/unchanged VA-2 scores (decreased score group vs increased/unchanged score group:-0.032±0.063 vs 0.018±0.043, t=2.305, P=0.035). The value of ΔFA in epileptic patients with increased/unchanged NHS3 scores (0.075±0.113) was higher compared to those with decreased scores (-0.079±0.099, t=2.804, P=0.010). Correlation analysis also showed the changes in FA values of epileptic lateral fasciculus (r=0.503, P=0.009) and arcuate fasciculus (r=0.602, P=0.001)were positively correlated with the changes in VA-2 and HNS3 scores, respectively. The seizure severity in patients with TLE was closely associated with the microstructure changes in the frontal and temporal white matter, especially the arcuate and uncinate tracts, on the same side that caused seizures, which may indicate the white matter remodeling and abnormal network reformation associated with seizures.

Evidence for Band Renormalizations in Strong-Coupling Superconducting Alkali-Fulleride Films.

There has been a long-standing debate about the mechanism of the unusual superconductivity in alkali-intercalated fullerides. In this Letter, using high-resolution angle-resolved photoemission spectroscopy, we systematically investigate the electronic structures of superconducting K_{3}C_{60} thin films. We observe a dispersive energy band crossing the Fermi level with the occupied bandwidth of about 130 meV. The measured band structure shows prominent quasiparticle kinks and a replica band involving the Jahn-Teller active phonon modes, which reflects strong electron-phonon coupling in the system. The electron-phonon coupling constant is estimated to be about 1.2, which dominates the quasiparticle mass renormalization. Moreover, we observe an isotropic nodeless superconducting gap beyond the mean-field estimation (2Δ/k_{B}T_{c}≈5). Both the large electron-phonon coupling constant and large reduced superconducting gap suggest a strong-coupling superconductivity in K_{3}C_{60}, while the electronic correlation effect is suggested by the observation of a waterfall-like band dispersion and the small bandwidth compared with the effective Coulomb interaction. Our results not only directly visualize the crucial band structure but also provide important insights into the mechanism of the unusual superconductivity of fulleride compounds.

[Comparison of clinical features of JAK2V617F gene mutation and non-mutation in patients with Budd-Chiari syndrome].

Objective: To investigate the clinical features of JAK2V617F gene mutation and non-mutation in patients with Budd-Chiari syndrome (BCS). Methods: 17 and 127 BCS cases with JAK2V617F gene mutation (mutation group) and non-gene mutation (non-mutation group) who were continuously treated with interventional therapy between January 2016 to December 2020 in the Affiliated Hospital of Xuzhou Medical University were selected as the research object for a comparative study. The hospitalization and follow-up data of the two groups were analyzed retrospectively, and the deadline for follow-up was June 2021. Quantitative data group differences were analyzed using the independent sample t-test and Wilcoxon rank sum test. Qualitative data group differences were analyzed with χ2 test or Fisher's exact test. Mann-Whitney U test was used to analyze the differences between groups in rank data. Kaplan-Meier method was used to calculate the patient survival and recurrence rate. Results: Age [(35.41±17.10) years vs. (50.09±14.16) years, t=3.915, P<0.001], time of onset (median duration: 3 months vs. 12 months), and the cumulative survival rate (65.5% vs 95.1%; χ2=5.21, P=0.022) were lower in mutation than non-mutation group. Aaspartate aminotransferase, alanine aminotransferase, prothrombin time, Child-Pugh score, Rotterdam score, Model for End-stage Liver Disease score, hepatic vein thrombosis incidence, and the cumulative recurrence rate after intervention were higher in mutation than non-mutation group. The above all indexes had statistically significant differences (P<0.05) between the groups. Conclusion: Younger age, acute onset, severe liver injury, high incidence of hepatic vein thrombosis, and poor prognosis are the features of patients with BCS with JAK2V617F gene mutation than non-mutation.

[The risk factors for regional lymph node metastasis of mismatch repair deficient colorectal cancer].

Objective: To explore the risk factors for regional lymph node (RLN) metastasis in colorectal cancer patients with mismatch repair deficiency (dMMR). Methods: The data of 357 dMMR colorectal cancer patients who underwent surgery in National Cancer Center from January 2012 to December 2016 was retrospectively analyzed. Univariate and multivariate analysis were used to identify the risk factors for RLN metastasis. Results: Among the 357 patients, 204 were male and 153 were female, 61.6% (220/357) lesion located in right half colon, while the other 16.2% (58/357) located in rectum. Univariate analysis showed that tumor size, differentiation, lymphovascular invasion, tumor deposit, postoperative pathologic T stage (pT), the number of negative lymph nodes and the expression of the MSH6 protein were significantly associated with RLN metastasis (P<0.05). All of the patients with well differentiation tumors (15 patients) or staged pT1 (13 patients) had no RLN metastasis. Multivariate analysis showed that tumor differentiation (OR=2.582, 95%CI=1.567-4.274, P<0.001), pT (OR=3.778, 95%CI=1.448-12.960, P=0.015) and the expression of MSH6 protein (OR=2.188, 95%CI=1.159-4.401, P=0.021) were independent risk factors for RLN metastasis. Conclusions: The postoperative pT stage, tumor differentiation and the expression of MSH6 protein are independent risk factors for RLN metastasis of dMMR colorectal cancer. Preoperative assessment of these factors may further improve the accuracy of predicting the risk of RLN metastasis.

[Long-term conditional disease-free survival for rectal cancer patients underwent neoadjuvant chemoradiotherapy].

Objective: To explore the application value of the conditional disease-free survival (cDFS) analysis in predicting prognosis of stage-specific rectal cancer patients underwent neoadjuvant chemoradiotherapy (nCRT). Methods: Clinicopathologic data of 436 patients with rectal cancer received nCRT and radical operation in Cancer Hospital, Chinese Academy of Medical Sciences between January 2004 and December 2016 were retrospectively reviewed. With reference to conditional probability, the 3-year cDFS of patients at different ypTNM stage after completion of nCRT was estimated using the Kaplan-Meier method. Results: There were 66 patients of ypTNM stage 0 (pathological complete response), 87 patients of ypTNM stage Ⅰ, 135 patients of ypTNM stage Ⅱ and 148 patients of ypTNM stage Ⅲ. The 3-year accumulated DFS of patients with ypTNM stage 0, ypTNM stage Ⅰ, ypTNM stage Ⅱ, and ypTNM stage Ⅲ were 97.0%, 93.1%, 85.2%, and 64.2%, respectively. On the condition of postoperactive disease-free survival for 1 year, 2 years, 3 years, 4 years, and 5 years, the corresponding 3-year cDFS of patients at ypTNM stage 0 were 97.0%, 95.5%, 96.9%, 98.4%, 100.0%, respectively. The corresponding 3-year cDFS of patients at ypTNM Ⅲ were 68.2%, 79.3%, 86.3%, 92.1%, 96.4%, respectively. The more advanced ypTNM staging resulted in the more improvement of 3-year cDFS being acquired. Conclusion: cDFS is a better method to reflect the dynamic changes of the prognosis of rectal cancer patients with nCRT in different ypTNM stage, and it is useful to guide the clinicians to assess the prognosis and propose appropriate surveillance.

[Clinicopathological and prognostic features of young onset patients with middle-low rectal cancer received neoadjuvant chemoradiotherapy].

Objective: To explore the clinicopathological and prognostic features of young onset patients with middle-low rectal cancer who received neoadjuvant chemoradiotherapy (NCRT). Methods: After NCRT, a total of 441 patients with primary middle-low rectal cancer treated with radical surgery at the Cancer Hospital, Chinese Academy of Medical Sciences (CHCAMS) from January 2004 to December 2016 were included. According to the age of disease onset, the patients were divided into the young group (51cases) and the middle-old group (390 cases), and the clinicopathological characteristics and survival of these patients were analyzed. Results: In the young group, 68.6% of patients received radical surgery within 7 weeks after NCRT, which was higher than 52.8% in the middle-old group (P=0.047). The stage ypTNM Ⅲ in the young group was 51.0%, higher than 34.1% in the middle-old group (P=0.027). The stage ypN+ in the young group was 51.0%, higher than 34.1% in the middle-old group (P=0.047), The incidence of disease progression in the young group was 39.2%, higher than 25.1% in the middle-old group (P=0.049). The incidence of distant metastasis in the young group was 35.3%, higher than 21.5% in the middle-old group(P=0.044). Most cases of disease progression occurred in the first 3 years after surgery for the young group, especially in the second year after surgery, the incidence of disease progression in the young group was 55.0%, higher than 26.5% in middle-old group (P=0.025). The 3-year and 5-year disease-free survival (DFS) rates for the young group were 63.7% and 58.2%, lower than 81.0% and 74.3% in the middle-old group (P=0.016), respectively. The 3-year and 5-year overall survival in the middle-old group (OS) rates for the young group were 85.4% and 69.2%, lower than 93.6% and 84.1% in the middle-old group (P=0.033), respectively. The multivariate analysis showed that, response of primary tumor (HR=4.804, 95% CI: 1.360-16.973) and total number of dissected lymph nodes (HR=4.336, 95% CI: 1.739-10.809) in the young group were independent prognostic factors related to DFS. The total dissected number of lymph nodes(HR=3.295, 95% CI: 1.076-10.091)was an independent prognostic factor related to OS. In the middle-old group, response of primary tumor (HR=2.626, 95% CI: 1.354-5.091), ypTNM stage (ypTNM Ⅲ: HR=5.837, 95% CI: 2.968-11.479) and tumor location distance from the anal verge (HR=0.500, 95% CI: 0.308-0.812) were independent prognostic factors related to DFS. Lymphovascular invasion (HR=0.500, 95% CI: 0.308-0.812) and ypTNM stage (ypTNM Ⅲ: HR=16.322, 95% CI: 5.049-52.771) were independent prognostic factors related to OS. Conclusions: Young onset rectal cancer patients are associated with shorter operation time interval, advanced pathological stage and poorer prognosis. More intensive adjuvant treatment and post-treatment surveillance should be conducted to young onset rectal cancer with NCRT.

[Expression and clinical significance of CXC chemokine ligand 10 in glioma].

Objective: To analyze the expression of CXC chemokine ligand 10 (CXCL10) in glioma and its clinical significance through bioinformatics. Methods: The expression level of CXCL10 in glioma, and its prognostic significance, gene ontology (GO) function annotation, Kyoto Encyclopedia of Genes and Genome (KEGG) pathway enrichment and the correlation of tumor cell purity were analyzed in TCGA, CGGA, MetaScape, TIMER databases. In addition, 34 clinical glioma tissues were collected for Western Blot and immunohistochemistry to further verify the correlation between CXCL10 and glioma. Results: CGGA and TCGA database analysis showed that with the increase of WHO grade, the expression of CXCL10 in gliomas increased (P<0.01). The overall survival rate of patients with high CXCL10 expression was significantly lower than that of patients with low expression (χ2 =148.1,P<0.05). Among patients with grade Ⅳ glioblastoma who received radiotherapy or chemotherapy, the patients with low CXCL10 expression were associated with good survival (χ2 =6.714,P<0.05;χ2 =5.618,P<0.05). Moreover, GO and KEGG analysis showed that genes co-expressed with CXCL10 were mainly enriched in the biological processes such as cytokine-mediated signaling pathways, regulating adaptive immune responses and inflammatory responses. Furthermore, TIMER database analysis showed that CXCL10 was negatively correlated with the purity of glioma cells (LGG: r=-0.129;GBM: r=-0.165;P<0.05). Similarly, clinical sample analysis also showed that the expression level of CXCL10 increased in glioma, and it increased with the grade of glioma (all P<0.05). Conclusion: The expression of CXCL10 is up-regulated in glioma as well as it increased with the malignant degree of glioma. At the same time, the high expression of CXCL10 in glioma is closely related to the poor prognosis of patients.

[Clinicopathological characteristics and prognostic analysis of patients with pathological complete response and near complete response after neoadjuvant treatment of rectal cancer].

Objective: To investigate the clinicopathological characteristics and prognosis of rectal cancer patients with pathological complete response and near complete response after neoadjuvant therapy. Methods: The clinicopathological data of patients who underwent neoadjuvant chemoradiotherapy plus radical surgery of rectal cancer in the Cancer Hospital of Chinese Academy of Medical Sciences from January 2004 to December 2016 were retrospectively collected. The clinicopathological characteristics and prognostic factor of patients with pathological complete response and near complete response were analyzed. Results: The clinical data of 142 patients were collected. There were 93 males and 49 females, aged from 24 to 81 years. The median disease-free survival was 53.9 months and the median overall survival was 55.0 months. Univariate analysis showed that the maximum diameter of scar or lesion, the status of lymph node metastasis and the distance between the lower edge of tumor and anal edge were associated with disease-free survival time; the maximum diameter of scar or lesion and the status of lymph node metastasis were associated with overall survival time. Multivariate Cox proportional hazards regression analysis showed that patients with scar or lesion diameter>3 cm (HR=4.406,95%CI:1.619-12.006), positive lymph node metastasis status (HR=4.102,95%CI:1.461-11.513) and tumor lower margin to anal margin distance ≤4 cm (HR=18.171,95%CI:2.357-140.073) had shorter disease-free survival time.The patients with scar or lesion diameter>3 cm (HR=8.573,95%CI:1.630-45.099) and lymph node metastasis status (HR=4.721, 95%CI:1.068-20.860) had shorter overall survival time. Conclusions: The overall prognosis of patients with pathological complete response or near complete response after neoadjuvant therapy for rectal cancer is better. The distance between the lower margin of the tumor and the anal edge, the status of lymph node metastasis and the maximum diameter of scars or lesion were the related factors affecting the prognosis of patients with rectal cancer.

[Analysis of curative efficacy of transjugular intrahepatic portosystemic shunt using viabahn stent in the treatment of Budd-Chiari syndrome with extensive hepatic vein occlusion].

Objective: To investigate the efficacy of transjugular intrahepatic portosystemic shunt (TIPS) using viabahn stent in patients with Budd-Chiari syndrome (BCS) with extensive hepatic vein occlusion. Methods: Technical success rates, portal pressure gradient (PPG), complications and shunt patency rate of 25 cases with BCS with extensive hepatic vein occlusion treated by TIPS using viabahn stent were retrospectively analyzed. Color Doppler ultrasound was used for postoperative follow-up. Patency rates were evaluated by Kaplan-Meier curve. Results: The technical success rate of TIPS was 100%. Mean PPG decreased from (22.7 ± 6.2) mmHg preoperatively to (9.7 ± 2.6) mmHg postoperatively (t = 9.58, P < 0.05). Hepatic encephalopathy incidence was 8.0% (2/25), and there were no complications such as intra-abdominal hemorrhage. Twenty-five cases were followed up for 1 to 39 ( mean 19.0 ± 11.9) months, and one patient died of liver failure three months after interventional treatment. The primary patency rates at 1, 2, and 3 years after interventional treatment were 91.3%, 91.3%, and 78.2%, respectively, while the repatency rates were 100%, 92.9%, and 92.9%, respectively. Conclusion: TIPS using viabahn stent can bring better short-term and mid-term curative efficacy in treatment of BCS with extensive hepatic vein occlusion.

EFFECTS OF ACUTE EXERCISE WITH DIFFERENT INTENSITIES ON GLYCEMIC CONTROL IN PATIENTS WITH TYPE 2 DIABETES MELLITUS.

OBJECTIVE: Exercise intensity is one of the most important factors that determines the effects of exercise; however, there is little known about the acute glycemic control of different exercise intensities on patients with Type 2 Diabetes Mellitus (T2DM). Here we aimed at exploring the influence of a single bout of exercise with different intensities on blood glucose levels in T2DM patients. METHODS: Fifteen subjects (54.7 ± 5.8 years old) participated in a session of walking (WG), jogging (JG), or sedentary control (CG) in a randomized order on three different days. Distances in both WG and JG were set as 2 Km with a speed set as 4~4.5 Km/h for walking and 5~6 Km/h for jogging based on pretrial test. Blood glucose levels at fasting (~6:30am), pre-exercise (~8:30am), post-exercise (~9am), 11am and 4pm were detected. RESULTS: Walking and jogging reached approximately moderate and high intensity based on the immediate post-exercise heart rate and RPE scores. Blood glucose levels at fasting, pre-exercise and 4pm were not substantially different among all groups (p > 0.05). JG had a significantly lower post-exercise blood glucose level (p < 0.05) when compared with CG and WG. The blood glucose level at 11am was notably lower in WG and JG than in CG (p < 0.05). CONCLUSIONS: Both a single bout of jogging and walking can lower postprandial blood glucose levels in T2DM patients. When matched for exercise distance, jogging represents a more effective strategy to immediately lower postprandial glucose levels than walking.

[The safety and efficacy of radical surgery after modified total neoadjuvant therapy for locally advanced rectal cancer].

Objective: To analyze the clinical-pathological data of patients with locally advanced rectal cancer who underwent modified total neoadjuvant therapy (TNT), and to evaluate the safety and efficacy of radical surgery after modified total neoadjuvant therapy. Methods: The clinical-pathological data of 30 locally advanced rectal cancer patients who underwent modified TNT (mTNT) followed by radical resection were retrospectively analyzed. The surgical procedure, postoperative complications, tumor regression grade, tumor downstaging and prognosis were analyzed. Results: The 30 patients included 24 males and 6 females with a median age of 55.5 years. All patients underwent radical surgery after neoadjuvant therapy, 14 patients received low anterior resection, 14 patients received abdominal perineal resection, and the other 2 patients received Hartmann procedure. All patients achieved R0 resection with a median operative time 220 minutes and the median intraoperative blood loss was 200 ml. The morbidity of postoperative complications was 20% (6/30), including dysuria in 2 patients, delayed healing of perineal incision in 2 patients, intestinal obstruction in 1 patient and pelvic hemorrhage in 1 patient. The median time to first flatus after surgery was 3 days and the median postoperative hospital stay was 8 days. Postoperative pathological results showed that 15 patients (50.0%) had severe tumor regression, including 4 patients (13.3%) achieved pathological complete response (pCR), 12 patients (40.0%) had moderate tumor regression, and 3 patients (10.0%) had minor tumor regression. Twenty patients had detailed pre-treatment clinical stage, and among those 20 patients, 15 patients (75.0%) and 13 patients (65.0%) achieved downstaging of tumor T stage and N stage, respectively. Only 2 patients appeared distant metastasis, and no patient had local recurrence. Conclusions: For locally advanced rectal cancer patients, mTNT doesn't increase the morbidity of postoperative complication and is a safe and effective treatment strategy with satisfactory short-term result.

[Prediction of short-term prognosis of hepatocellular carcinoma after TACE surgery based on MRI texture analysis technology].

Objective: To explore the feasibility of short-term efficacy prognosis prediction model for HCC patients undergoing transcatheter arterial chemoembolization (TACE) based on MRI-based radiomics technique. Methods: A total of 123 patients with liver cancer who received TACE treatment in Lishui Central Hospital from June 2016 to July 2018 were retrospectively collected, including 90 males and 33 females, with an average age of 24-83 (58±10) years. All the patients were pathologically confirmed as hepatocellular carcinoma and underwent MRI scan before surgery.All patients were followed up 3-4 months after TACE, and further divided into training group (n=85, 42 of which were effective and 43 cases were ineffective) and the validation group (n=38, 19 of which were effective and 19 were ineffective) according to the modified response evaluation criteria in solid tumors (mRECIST). There was no statistical difference in the general information between the two groups of patients, which was comparable. Then, preoperative T(2)WI images were used for radiomics analysis, texture parameters were screened based on R language, and short-term efficacy prediction model of TACE for training group and verification group was constructed. Results: T(2)WI image analysis of each patient received 396 different texture parameters, and further used Lasso dimensionality reduction and 10 times cross-validation screening to obtain 5 characteristic texture parameters, specifically stdDeviation, ClusterProminence_angle135_offset4, Correlation_angle135_offset4, Inertia_angle135_offset4, InverseDifferenceMoment_angle45_offset4. According to the above five texture parameters and their corresponding coefficient values, the corresponding radiomics scores (Radscore) were calculated, and the prediction models of the training group and the verification group were further constructed.It was found that the area under the ROC curve of the training group was 0.812 (95%CI: 0.722-0.901), the sensitivity and specificity were 83.7% and 69.0%, respectively. The area under the ROC curve of the validation group was 0.801 (95%CI:0.654-0.947), and the sensitivity and specificity were 89.5% and 63.2%, respectively. Conclusion: The constructed TACE prediction model in the present study has high prediction accuracy, sensitivity and specificity.The short-term efficacy prognosis prediction model for HCC based on MRI is constructed, stable and reliable.

[A multicenter, randomized, open and positive parallel controlled clinical study of clotrimazole vaginal expansion suppository and vaginal tablet in the treatment of mild and moderate vulvovaginal candidiasis].

Objective: Using clotrimazole vaginal tablet as a positive control, to evaluate the results of clotrimazole vaginal expansion suppository in the treatment of mild and moderate vulvovaginal candidiasis in terms of efficacy, patient satisfaction, side effects, and recurrence rate. Methods: This study was jointly conducted by 5 hospitals from August 2017 to October 2018, patients with mild and moderate vulvovaginal candidiasis confirmed by fungal culture and symptoms scores were selected. They were randomized to experimental group and control group as 1∶1 ratio. In the experimental group (n=105), the subjects applied clotrimazole vaginal expansion suppository (150 mg) daily at night for 7 days. In the control group (n=106), the subjects used a single dose of clotrimazole vaginal tablet (500 mg). Follow-ups were performed at (8±3) and (30±5) days after the discontinuation of the drugs, respectively. The difference in clinical symptoms and signs scores was used to evaluate the improvement of clinical symptoms, and the patient's satisfaction and side effects were recorded. Results: At the first follow-up, the experimental group and control group were followed up by fungal culture on the cure rate [66.7% (70/105) versus 63.2% (67/106), P>0.05] and total effective rate [98.1% (103/105) versus 99.1% (105/106), P>0.05], the differences were not statistically significant. At the second follow-up, the recurrence rates of the experimental group and the control group were 5.7% (4/70) and 14.9% (10/67), respectively, with no significant difference (P>0.05). In the evaluation of patient satisfaction, the leakage of the drug in the experimental group was significantly better than that in the control group (P<0.01). The side effects mainly included vaginal stimulation, itching and burning sensation, and there was no statistical difference between the two groups (χ2=1.070, P=0.586). Conclusions: In the treatment of mild and moderate vulvovaginal candidiasis, clotrimazole vaginal expansion suppository is no less effective than clotrimazole vaginal tablet, and there is no significant difference in the recurrence rate between the two. In terms of patient satisfaction, clotrimazole vaginal expansion suppository is superior to clotrimazole vaginal tablet.

[Teleost Type 2 Interleukin-1 Receptor (IL-1R2) from the Spotted Halibut (Verasper variegatus): 3D Structure and a Role in Immune Response].

The type 2 interleukin-1 receptor (IL-1R2) is one of natural IL-1ß singling inhibitors in mammals. We cloned and sequenced the IL-1R2 gene in V. variegatus (VvIL-1R2). The phylogenetic analysis showed that the molecular structure VvIL-1R2 is similar to that of its orthologues in other vertebrates. The expression levels of VvIL-1R2 are relatively high in the peripheral blood leukocytes (PBLs), gill, and spleen. In addition, peculiar expression patterns for his molecule were detected at various developmental stages, implying that in flatfishes the IL-1R2 may have be important for embryonic development and metamorphosis. In PBLs, the treatment with pathogen-associated molecular patterns (PAMPs) induced a significant and rapid up-regulation of VvIL-1R2, pointing at its involvement in the immune responses against bacterial and viral pathogens.

[Preliminary application of transjugular intrahepatic portosystemic shunt in individualized treatment of patients with cirrhotic portal hypertension complicated with refractory ascites and variceal hemorrhage].

Objective: To investigate the feasibility, efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) in the individualized treatment of patients with refractory ascites and variceal hemorrhage caused by portal hypertension. Methods: Prospective study of clinical data of 47 patients with portal hypertension and refractory ascites and variceal bleeding admitted to the Affiliated Hospital of Xuzhou Medical University from August 2017 to December 2018, 26 males and 21 females, aged 23-75 (52±14) years old. The Viabahn stent was used to control the diameter of the shunt and the preoperative interval of PPG after individualized TIPS was determined according to the preoperative liver function Child-Pugh classification. The PPG of the Child A and B patients was <10 mm Hg (1 mmHg=0.133 kPa), Child-Pugh C grade patients with postoperative PPG interval values of 12 to 15 mmHg. The success rate, hemostasis rate, ascites remission rate, and complication rate were recorded. Results: Forty-seven patients were with a success rate of 100%, and there was no surgically related fatal complications. The portal pressure gradients of patients with Child-Pugh A, B and Child-Pugh C were reduced from preoperative (22.5±5.4), (24.4±2.6) mm Hg to postoperative (8.8±2.5), (13.2±1.1) mm Hg (all P<0.05). All the patients were followed up for 6 to 24 months, with a median follow-up of 13 months. The success rate of hemostasis in patients with upper gastrointestinal bleeding was 93.5% (29/31), the remission rate of patients with refractory ascites was 14/16, the postoperative rebleeding rate was 6.5% (2/31), the incidence of hepatic encephalopathy was 8.5% (4/47), and the shunt disorder was 2.1% (1/47). Conclusion: The use of Viabahn stent for individualized TIPS in the treatment of portal hypertension with refractory ascites and variceal hemorrhage is feasible, and the clinical efficacy is affirmative, which can reduce the incidence of postoperative hepatic encephalopathy and shunt dysfunction.

Significant improvement of intestinal microbiota of gibel carp (Carassius auratus gibelio) after traditional Chinese medicine feeding.

AIMS: Increasing attention has been attracted to intestinal microbiota, due to interactions with nutrition, metabolism and immune defence of the host. Traditional Chinese medicine (TCM) feed additives have been applied in aquaculture to improve fish health, but the interaction with fish gut microbiota is still poorly understood. This study aimed to explore the effect of adding TCM in feed on the intestinal microbiota of gibel carp (Carassius auratus gibelio). METHODS AND RESULTS: Bacterial communities of 16 fish intestinal contents and one water sample were characterized by high-throughput sequencing and analysis of the V4-V5 region of the 16S rRNA gene. The results showed that the composition and structure of the bacterial community were significantly altered by the TCM feeding. Some phyla increased markedly (Proteobacteria, Actinobacteria, Acidobacteria, etc.), while Fusobacteria were significantly reduced. Concurrently, the richness and diversity of the taxonomic units increased, and the microbiota composition of TCM-treated fish was more homogeneous among individuals. At the genus level, the addition of TCM tended to reduce the incidence of potential pathogens (Aeromonas, Acinetobacter and Shewanella), while stimulating the emergence of some potential probiotics (Lactobacillus, Lactococcus, Bacillus and Pseudomonas). CONCLUSIONS: These data suggested that the feed additive could regulate the fish intestinal microbiota by reinforcing the microbial balance. SIGNIFICANCE AND IMPACT OF THE STUDY: This study may provide useful information for further application of TCM for diseases prevention and stress management in aquaculture.

Outbreak of mass mortality of yearling groupers of Epinephelus (Perciformes, Serranidae) associated with the infection of a suspected new enteric Sphaerospora (Myxozoa: Myxosporea) species in South China Sea.

A suspected new enteric Sphaerospora species was believed to be directly associated with the mass mortality of yearling groupers of Epinephelus spp. in South China. The epizootic generally emerged from late September to late April of the following year. The infection prevalence and mortality rate were significantly negatively correlated with fish size. Clinical signs included anorexia, cachexia and extrusion of white pulp-like substance from anus after gentle pressure on the abdomen. Upon necropsy, severe intestinal oedema, thin and transparent intestinal wall, swollen spleen, kidney and gall bladder could be observed. Wet preparation of the infected samples showed large amount of typical disporous plasmodia of the genus Sphaerospora, but no mature spores were observed. Epidemiological investigation showed that this parasite exclusively infected Epinephelus groupers. Histopathologically, this species mainly infected the epithelium of intestine and kidney tubules and caused severe epithelia sloughing and the collapse of intestinal villus. Interestingly, this enteric myxosporidiosis did not cause severe emaciation of infected fish for mass mortality usually emerged within 2-3 days after appearance of clinical signs. The species was most genetically related to Sphaerospora fugu (89% sequence identity) and phylogenetically positioned within marine Sphaerospora lineage. This is the first report of enteric sphaerosporosis of groupers.

[Expert consensus on the diagnosis and treatment of cryptococcal meningitis].

Cryptococcal meningitis is a common and refractory central nervous system infection, with high rates of mortality and disability. The experts of the Society of Infectious Diseases of Chinese Medical Association have reached this consensus after a thorough discussion. Based on the current situation of cryptococcal meningitis in China, the management of cryptococcal meningitis includes 6 aspects: introduction, microorganism identification, clinical manifestations and diagnosis, principles of antifungal therapy, treatment of refractory and recurrent meningitis, treatment of intracranial hypertension. There is not a separate consensus on human immunodeficiency virus (HIV) infection in patients with cryptococcal meningitis. This article focuses on different antifungal regimens and reducing intracranial pressure by reference to Infectious Disease Society of America (IDSA) guidelines. The importance of early diagnosis, combined long-term antifungal therapy, control of intracranial hypertension are emphasized.

The maximum predicted content of cation vacancies in inorganic and organic-inorganic perovskites: the role of the tolerance factor.

The maximum content of cation vacancies in perovskites determines the maximum adjustment to the physical properties. By using the classical criterion of the tolerance factor, we put forward a new method to obtain the maximum content of cation vacancies in perovskites. The effective ionic radius was calculated using the weighted average method, and the limit of tolerance factors was used to determine the maximum value of the cation vacancies. The calculated results of the La1-xMnO3 and La0.75Sr0.25Mn1-yO3 materials coincide with experimental results. For application, [(A1)1-x(A2)x]1-z1(B1B2)X3 or [(A1)1-x(A2)x](B1B2)1-z2X3 (X = O, F, Cl, Br, I) inorganic and hybrid organic-inorganic perovskite materials with vacancies at the A or B sites were predicted successfully, which provides a new method to improve the physical properties of perovskite materials.
