Objective:To compare single-cell transcriptome sequencing data from skin samples of patients with atopic dermatitis (AD) and those from skin samples of healthy controls, and to investigate immunometabolic characteristics of inflammatory dendritic epidermal cells (IDECs) in skin lesions of patients with AD.Methods:An in-depth analysis was carried out on previously published single-cell sequencing data from 8 AD patients and 7 healthy controls in the Gene Expression Omnibus database (GSE 153760). Marker genes were used to screen out IDECs, and differentially expressed genes in IDECs between the two groups were analyzed. Kyoto Encyclopedia of Genes and Genomes enrichment analysis was performed on these differentially expressed genes, the "AddModuleScore" function in the Seurat package was used to evaluate the IDEC-involved inflammatory and metabolic pathways in the two groups, and Mann-Whitney rank sum test was used for statistical analysis; correlations between the IDEC-involved metabolic and inflammatory pathways were evaluated using the above scores and the "cor" and "cor.test" functions in R packages.Results:A large number of IDECs infiltrating the skin lesions of AD patients highly expressed Th2 chemokines (CCL17), antigen presentation-related genes (CD1B), endothelial growth-related genes (TYMP, AREG), inflammation-related genes (S100A8, S100A10, LGALS1), stromal fibrosis-related genes (MMP12, ADAM19), metabolism-related genes (LDHA, LIPA, GLUL), and danger signaling-related genes (HSPA1B, HSP90AA1, HSPB1, HSPH1). The activities of glucose energy metabolism, glycolytic metabolism, nucleotide metabolism, glutamate and glutamine metabolism, and amino acid metabolism were significantly upregulated in IDECs in AD patients, and were positively correlated with Th2 inflammation levels; the activities of oxidative phosphorylation and lipid metabolism were significantly downregulated in IDECs in AD patients, and the lipid metabolism level was negatively correlated with Th2 inflammation levels. Glutamine metabolism and glucose energy metabolism activities were positively correlated with Th22 inflammation levels; Th1 and Th17 inflammation levels were negatively correlated with the activities of pentose phosphate metabolism, nucleotide metabolism, glycolytic metabolism, and amino acid metabolism pathways.Conclusion:The inflammation- and metabolism-related genes were abnormally expressed in IDECs in skin lesions of AD patients, and activities of multiple metabolic pathways were markedly upregulated in IDECs, among which the glycolysis metabolism activity was mostly correlated with Th2 inflammation levels.

Objective To explore the expression level of Sox11 gene in cervical cancer cell lines and cervical pathology tissue .Methods The expression of Sox11 protein was detected in cervical cancer cell lines HeLa , CaSki ,SiHa and C-33A as well as NC ,LSIL ,HSIL and CC using immunohistochemistry and Western blot .We analyzed the relationship between Sox11 expression in cervical cancer and clinicopathologic parameters .Results The expression of Sox11 protein in normal cervical tissue ,low-grade cervical squamous intraepithelial neoplasia was significantly higher than that in the high-grade cervical squamous intraepithelial neoplasia and invasive cervical cancer tissue , and the expression was reduced with the progression of cervical lesions .The expression of Sox11 protein in the invasive cervical cancer was reduced with increased malignant degree .The expression of Sox11 protein in the invasive cervical cancer was significantly correlated with HPV infection ,but not associated with the age , clinical stage ,lymph node metastasis or muscular infiltration depth .Conclusion Sox11 expression is negatively correlated with cervical cancer development ,suggesting that as a tumor suppressor gene ,Sox11 may play a role in cervical cancer development and its absence or low expression is associated with the development of cervical cancer and is an early event of cervical carcinogenesis and may be a sign of malignant change of cervical tissue .

OBJECTIVETo study the role of aquaporin 5(AQP5) in regulating the cell proliferation and apoptosis of human colorectal cancer cells and explore the possible mechanism.

METHODSA small interfering RNA (siRNA) targeting AQP5 was used to suppress endogenous AQP5 expression in the human colorectal cancer cell lines COLO 205 and SW480, and the transfection efficiency of AQP5 siRNA was determined using immunofluorescence assay and PCR. The changes in the proliferation of the transfected cells was evaluated with MTT assay, and the cell apoptosis was analyzed using Annexin V-FITC/PI and TUNEL assays; the changes of Bax and Bcl2 expressions in the cells were determined using RTPCR and Western blotting.

RESULTSTransfection with AQP-5-siRNA resulted in a significant reduction (up to 90%) of AQP-5 expression in COLO 205 and SW480 cells. MTT assay showed that AQP-5-siRNA transfection significantly inhibited the cell proliferation compared NS siRNA transfection (P<0.05). Flow cytometric analysis revealed significantly increased apoptotic rate of cells following AQP-5-siRNA transfection compared with NS?siRNA transfection(P<0.05). Real-time quantitative RT-PCR and Western blotting demonstrated that AQP-5-siRNA transfection significantly increased Bax and Bcl-2 expressions at both mRNA and protein levels in the cells.

CONCLUSIONAQP5-siRNA can promote apoptosis of colorectal cancer cells in vitro possibly in relation to its effects on Bax and Bcl expressions.

AIMTo explore the feasibility and safety of greenlight photoselective vaporization of the prostate (PVP) on high-risk patients presenting with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH) and to evaluate their clinical and voiding outcome.

METHODSA total of 85 high-risk patients with obstructive BPH underwent PVP with an 80 W potassium-titanyl-phosphate laser, which was delivered through a side-deflecting fiber with a 23 Fr continuous flow cystoscope. Operative time, blood loss, indwelling catheterzation, international prostate symptom score (IPSS), quality of life score (QoL), uroflowmetry, postvoid residual urine volume and short-term complication rates were evaluated for all patients.

RESULTSAll patients got through the perioperative period safely. The chief advantages of PVP were: short operative time (25.6 +/- 7.6 min), little bleeding loss (56.8 +/- 14.3 mL) and short indwelling catheterization (1.6 +/- 0.8 d). The IPSS and QoL decreased from (29.6 +/- 5.4) and (5.4 +/- 0.6) to (9.5 +/- 2.6) and (1.3 +/- 0.6), respectively. The vast majority of patients were satisfied with voiding outcome. The mean maximal urinary flow rate increased to 17.8 mL/s and postvoid residual urine volume decreased to 55.6 mL. These results are significantly different from preoperative data (P < 0.05). No patient required blood transfusion or fluid absorption. There were few complications and very high patient satisfaction after operation.

CONCLUSIONPVP has a short operative time and high tolerance, and is safe, effective and minimally invasive for high-risk patients, therefore it might be considered as a good alternative treatment for high-risk patients with obstructive urinary symptoms as a result of BPH.

OBJECTIVETo investigate clinical efficacy and safety of CMOD regimen as the first treatment for the aged new-diagnosed patients with peripheral T-cell lymphoma.

METHODSSeventy-six patients diagnosed as peripheral T cell lymphoma according to chemotherapy were divided into the 2 group: A and B groups. The patients in A group received CMOD regimen (38 cases) and the patients in B group received CHOP regiment (38 cases). The clinical efficacy, PFS (progression-free survival), OS and the adverse reactions in the 2 groups were compared.

RESULTSThe total effeciency rate was not statistically different between CMOD(64.52%) and CHOP groups (58.06%) (P>0.05). The adverse reactions in 2 groups were as follows: myelosuppression, mucositis, gastrointestinal reactions, fever, liver dysfunction, neurotoxicity, and alopecia etc. The incidence of alopecia and the grade III and IV of neutropenia in the CMOD group (34.21%, 13.16%) were statistically significantly lower than those in the CHOP group (84.21%, 34.21%) (P<0.05). The progression-free survival and 1-year overall survival of observation group (10.98±2.23 months, 14.43±2.48 months) were significantly higher than those in the CHOP group(8.31±2.62 months, 10.93±2.07 months) (P<0.05).

CONCLUSIONThe clinical efficacy of CMOD regimen has been confirmed to be equivalent with CHOP regimen for the aged new-diagnosed patients with peripheral T-cell lymphoma. This regimen can prolong the progression-free survival and overall survival to some extent and reduce the incidence of hair loss and neutropenia, which may be applied to the clinical practice.

OBJECTIVE: To compare the plasma components of frozen plasma (FP) and fresh frozen plasma (FFP). METHODS: Twenty samples of FP and 20 samples of FFP from Beijing Red Cross Blood Center were randomly selected. Immediately after plasma melting, 12 plasma components including coagulation factor, fibrinolytic system and anticoagulation protein were detected, including activated partial thromboplastin time (APTT), prothrombin time (PT), coagulation factor Ⅷ (FⅧ) activity, coagulation factor Ⅴ (FⅤ) activity, fibrinogen(FIB) level, ADAMTS-13 activity, von Willebrand factor(vWF) activity, D-dimer (D-dimer, DD), fibrin degradation products (FDP), antithrombin (AT), protein C (PC), and protein S (PS). All these coagulation components between the two types of plasma were compared and analyzed. RESULTS: Compared with FFP, APTT in FP was significantly prolonged(t=3.428, P<0.01), and PT was also significantly prolonged(z=-2.140, P<0.05), and FⅧ activity was decreased (t=-3.372, P<0.01), but all in the reference range, and PS activity was decreased(t=-2.458，P＜0.05), there was no statistical difference in the other part between two types of plasma(P>0.05). CONCLUSION FP can substitute FFP in the treatment of some diseases, although it is lack of some coagulation factors and anticoagulation protein.

Qingxin Lianzi Yin （QXLZY）， as an ancient classical formula for clearing the heart and nourishing the Yin， was composed of nine herbs （Scutellariae Radix， Ophiopogonis Radix， Lycii Cortex， Plantaginis Semen， Glycyrrhizae Radix et Rhizoma Praeparata Cum Melle， Nelumbinis Semen， Poria， Astragali Radix and Ginseng Radix et Rhizoma）， coming from Prescriptions of the Bureau of Taiping People's Welfare Pharmacy. It could clear away the heart-fire， promote the interaction of the heart and kidney， replenish Qi and Yin， and stop strangury-turbidity. It was used to treat gonorrhea of urination， seminal emission， restlessness， wasting-thirst and so on. At present， the usage and dosage of QXLZY and its addition and subtraction are different in clinical practice. Most of the studies just focus on its clinical efficacy， and there is few review literature reflecting its historical evolution. Based on this， this paper systematically clarified the historical evolution， composition， preparation， interpretation， function， and modern clinical application of QXLZY. This work has been explained the historical evolution of QXLZY， and found that it was wildly used in modern clinical， especially suitable for the treatment of chronic urinary system diseases. At the same time， QXLZY also had significant therapeutic effects on neurasthenia， stomatitis， diabetic nephropathy and other aspects. Through the comprehensive analysis of ancient and modern literature， this work explores the true connotation of QXLZY from the perspective of traditional Chinese medicine theory， which can point out the direction of the clinical application and positioning of this famous classical formula after it comes into the market， and also can provide reference basis for its subsequent in-depth research and development.
