This study aims to identify the active components and the mechanism of Jingqi Yukui Capsules(JQYK) in the treatment of gastric ulcer based on network pharmacology, and verify some key targets and signaling pathways through animal experiment. To be specific, first, the active components and targets of JQYK were retrieved from a Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine(BATMAN-TCM) and Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and the targets of gastric ulcer from GeneCards and Online Mendelian Inheritance in Man(OMIM) with the search term "gastric ulcer". The common targets of the two were the potential targets of the prescription for the treatment of the di-sease. Then, protein-protein interaction(PPI) network of key targets were constructed based on STRING and Cytoscape 3.7.2, followed by Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment by matescape database and pathway visualization by Omicshare. For the animal experiment, the improved method of Okabe was used to induce gastric ulcer in rats, and the model rats were classified into the model group, JQYK high-dose(JQYK-H), medium-dose(JQYK-M), and low-dose(JQYK-L) groups, Anweiyang Capsules(WYA) group, and Rabeprazole Sodium Enteric Capsules(RBPZ) group. Normal rats were included in the blank group. Rats in the blank group and model group were given distilled water and those in the administration groups received corresponding drugs. Then gastric ulcer healing in rats was observed. The changes of the gastric histomorphology in rats were evaluated based on hematoxylin-eosin(HE) staining, and the content of inducible nitric oxide synthase(iNOS) in rat gastric tissue was detected with Coomassie brilliant blue method. The mRNA and protein levels of some proteins in rat gastric tissue were determined by real-time quantitative polymerase chain reaction(RT-qPCR) and Western blot(WB) to further validate some key targets and signaling pathways. A total of 206 active components and 535 targets of JQYK, 1 305 targets of gastric ulcer, and 166 common targets of the disease and the drug were yielded. According to PPI analysis and KEGG pathway enrichment analysis, multiple key targets, such as interleukin-6(IL-6), tumor necrosis factor(TNF), mitogen-activated protein kinase 1(MAPK1), MAPK3, and MAPK14, as well as nuclear factor kappa-B(NF-κB) signaling pathway, IL-17 signaling pathway, and leukocyte transendothelial migration in the top 20 key signaling pathways were closely related to inflammation. The key protein p38 MAPK and NF-κB signaling pathway were selected for further verification by animal experiment. The gastric ulcer in the JQYK-H group recovered nearly to the level in the blank group, with significant decrease in the content of iNOS in rat gastric tissue and significant reduction in the mRNA and phosphorylation levels of p38 MAPK and the mRNA and protein levels of NF-κB p65 in rat gastric tissue. The results indicated that JQYK can inhibit the phosphorylation of the key protein p38 MAPK and the expression of NF-κB p65 in the NF-κB signaling pathway, thereby exerting the anti-inflammatory effect and effectively improving the quality of gastric ulcer healing in rats. Thus, the animal experiment result verifies some predictions of network pharmacology.

BACKGROUNDOld pelvis fractures are among the most challenging fractures to treat because of their complex anatomy, difficult-to-access surgical sites, and the relatively low incidence of such cases. Proper evaluation and surgical planning are necessary to achieve the pelvic ring symmetry and stable fixation of the fracture. The goal of this study was to assess the use of three-dimensional (3D) printing techniques for surgical management of old pelvic fractures.

METHODSFirst, 16 dried human cadaveric pelvises were used to confirm the anatomical accuracy of the 3D models printed based on radiographic data. Next, nine clinical cases between January 2009 and April 2013 were used to evaluate the surgical reconstruction based on the 3D printed models. The pelvic injuries were all type C, and the average time from injury to reconstruction was 11 weeks (range: 8-17 weeks). The workflow consisted of: (1) Printing patient-specific bone models based on preoperative computed tomography (CT) scans, (2) virtual fracture reduction using the printed 3D anatomic template, (3) virtual fracture fixation using Kirschner wires, and (4) preoperatively measuring the osteotomy and implant position relative to landmarks using the virtually defined deformation. These models aided communication between surgical team members during the procedure. This technique was validated by comparing the preoperative planning to the intraoperative procedure.

RESULTSThe accuracy of the 3D printed models was within specification. Production of a model from standard CT DICOM data took 7 hours (range: 6-9 hours). Preoperative planning using the 3D printed models was feasible in all cases. Good correlation was found between the preoperative planning and postoperative follow-up X-ray in all nine cases. The patients were followed for 3-29 months (median: 5 months). The fracture healing time was 9-17 weeks (mean: 10 weeks). No delayed incision healing, wound infection, or nonunions occurred. The results were excellent in two cases, good in five, and poor in two based on the Majeed score.

CONCLUSIONSThe 3D printing planning technique for pelvic surgery was successfully integrated into a clinical workflow to improve patient-specific preoperative planning by providing a visual and haptic model of the injury and allowing patient-specific adaptation of each osteosynthesis implant to the virtually reduced pelvis.

OBJECTIVETo explore the Intervention effect of Rosiglitozone in ovarian fibrosis of PCOS rats.

METHODS60 female SD rats were randomly divided into 3 groups: control group, model group and treatment group. The model and treatment groups were established by subcutaneous injection of DHEA, while the treatment group was given RGZ. The serum hormone values, pathohistology of ovarian structure of rats, ovarian ultrastructure and the expressions of TGF-β(1) and CTGF were detected.

RESULTSThe PCOS model was established successfully. The expression intensity of TGF-β(1) and CTGF in Oocytes of the PCOS groups was 9.545±2.954 and 9.665±2.400, respectively and was significantly higher than that of the control group 6.636±2.264 and 7.036±2.133; after treatment with rosiglitazone, the expression was significantly decreased 6.980±2.421 and 6.642±2.721 as compared with that of the model group (P<0.05, P<0.001). The values in serum of the PCOS groups were 3.749±2.054 and 0.265±0.129, and 1.914±1.801 and 0.096±0.088 in the control group which had statistically significant difference (P<0.05, P<0.001). After treatment with rosiglitazone, the values were 2.3100±1.825 and 0.112±0.187 and were significantly different with those of the model group (P<0.05, P<0.001).

CONCLUSIONTGF-β(1) and CTGF play an important role in the development of ovary fibrosis in PCOS. However, RGZ may postpone the development of fibrosis by decreasing the levels of TGF-β(1) and CTGF.

OBJECTIVETo investigate apoptosis of tumor infiltrating dendritic cells (TIDC) and their expression of Fas/FasL (CD95/CD95L) in human endometrioid adenocarcinoma.

METHODSThe apoptotic rate of TIDC was measured in 45 cases of endometrioid adenocarcinoma and 20 cases of normal endometrium tissues (control) by double-label immunohistochemistry using the monoclonal antibody S-100 protein and TUNEL technique. The expressions of Fas and FasL in TIDCs were detected using double-label immunohistochemistry and imaging analysis.

RESULTSThe apoptotic rate of TIDCs in endometrioid adenocarcinoma were significantly higher than that in normal endormetrium [(13.02∓0.64)% vs (6.82∓0.53)%, P<0.05]. The expression levels of Fas in the TIDCs were significantly lower, whereas FasL expression significantly higher in endometrioid adenocarcinoma than in normal endormetrium (7.88∓1.05 vs 19.25∓3.03, P<0.05; 12.95∓2.25 vs 7.51∓1.14, P<0.05).

CONCLUSIONIncreased apoptosis of the TIDCs and abnormal expression of Fas/FasL in TIDCs in endometrioid adenocarcinoma may lead to tumor immune escape.

OBJECTIVETo study the effect of inactivated and un-inactivated pharmaco-serum of diabetic rats fed with Chinese herbs Qianggubao decoction on the proliferation of osteoblast cells (OB)cultured in vitro.

METHODSOB was isolated from the skull of newly born SD rats aged 1 to 2 days by means of Trypsin-collagenase digestion and identified by image analysis under inverted microscope, V-G collagen staining, ALP staining, calcification nod staining etc. After the OB was identified, in activated and un-inactivated pharmaco-serum of diabetic rats fed with Qianggubao decoction of ferent phase (rats were fed with medicine 3 days or 5 days after last fed with medicine 1 hour or 3 hours) and concentration (5%, 10%, 20%) were added to the OB and incubated. After determined times, the effects of the proliferation of osteoblasts were detected by MTT analysis.

RESULTSThere was significant difference between un-inactivated pharmaco-serum and inactivated pharmaco-serum on the proliferation of osteoblasts, and un-inactivated serum had stronger effects to improve the proliferation of osteoblasts (P < 0.01 or P < 0.05).

CONCLUSIONUn-inactivated and inactivation pharmaco-serum of diabetic rats fed with Chinese herbs Qianggubao decoction can influence the proliferation of, and the un-inactivated pharmaco-serum has stronger effects.

OBJECTIVETo investigate the optimum phase and dose of pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) on the differentiation and mineralization of osteoblast (OB). METHODS (OB) was isolated from the skull of 10 newly born SD rats aged 1 to 2 days by means of Trypsin-collagenase digestion. After the OB was identified, different kinds of pharmaco-serum of diabetic rats fed with inactive Qianggubao decoction ([Chinese characters: see text]) of different phase (rats were fed with medicine three days or five days after last fed with medicine one hour or three hours) and concentration (5%, 10%, 20%) were added to the OB and incubated. After 7 days and 18 days of culture,the effects of the differentiation and mineralization of osteoblast were detected.

RESULTSThe secretion of ALP and formation of mineralized nodules of osteoblast in the different doses of pharmaco-serum groups were almost the same as that of normal control group, but were superior to that in the model control group. And the group with concentration of 20% pharmaco-serum was the best in the secretion of ALP and formation of mineralized nodules of osteoblast. As to the phases of pharmaco-serum, the best one on the differentiation and mineralization of osteoblast was the serums from diabetic rat-model fed with Qianggubao decoction ([Chinese characters: see text]) three days or five days, after one hour of last fed with medicine.

CONCLUSIONThe pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) can promote the differentiation and mineralization of osteoblast. Allow for time and the cost of experiment,we presume that pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) three days, after one hour of last fed, with concentration of 20% and not-inactivation is the optimum on the differentiation and mineralization of osteoblast.

OBJECTIVETo investigate neuroendocrine differentiation and its mechanism in ovarian epithelial tumors.

METHODSNeuroendocrine (NE) cells were identified by immunohistochemical staining for chromogranin A and synaptophysin in 79 cases of ovarian epithelial tumor and 22 cases of normal ovary. Double-labeling technique was used for simultaneous detection of CgA and epithelial membrane antigean (EMA), and the staining intensity was quantitatively evaluated using an image analysis system.

RESULTSThe positive staining rate for CgA and SYN in ovarian epithelial tumors was 59.4% and 65.36%, respectively, which was higher than that in normal ovary (P=0.000), in which numerous NE cells were found. Both the number and staining intensity of NE cells in ovarian epithelial tumor were increased as compared with normal ovary. Cells co-expressing CgA and EMA were detected in the ovarian epithelial tumors.

CONCLUSIONThe presence of NE cells in ovarian epithelial tumor suggests heterogeneity of the tumors, and the occurrence of "multidirectional differentiation cells" within the these tumors indicates that NE cells might derive from malignant cells with multidirectional differentiation capacity.

The present study was aimed at investigating the expression of calbindin-D28k (CaBP-D28k) in human fallopian tube, which were collected from 33 childbearing age women undergoing abdominal hysterectomy with adnexectomy for benign disease in the pelvic cavity. These women had normal menstrual cycle and history of normal pregnancy. Isthmus, ampullary and umbrella segments of fallopian tubes were respectively collected. These specimens were divided into 6 groups based on their menstrual cycles: early-proliferative stage (n=6), mid-proliferative stage (n=5), late-proliferative stage (n=5), early-secretory stage (n=7), mid-secretory stage (n=5) and late-secretory stage (n=5). The expressions of CaBP-D28k protein and mRNA in fallopian tubes were determined by immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR) methods. Positive expressions of CaBP-D28k protein and mRNA were observed in human fallopian tubes. There was no significant difference in the expression of CaBP-D28k protein among the isthmus, ampulla and umbrella segments in the same phase of menstrual cycle (P>0.05). However, in the menstrual cycle, the expression level of CaBP-D28k protein in the epithelium was the lowest during the early- and mid-proliferative stages and increased in both the late-proliferative and early-secretory stages (P<0.05), and then decreased in the mid- and late-secretory stages (P<0.05). The expressed CaBP-D28k protein was disposed to gobbets or dispersed sheets in cytoplasm in the early- and mid- proliferative stages, and showed concentrated granules on the top of cells in the late-proliferative and early-, mid-secretory stages. Then in the late-secretory stage redistribution renewed as in the early- and mid-proliferative stages. The CaBP-D28k mRNA obviously increased in the late-proliferative and early-secretory stages (P<0.05). These findings indicate that the expressions of CaBP-D28k protein and mRNA exist in human fallopian tubes and exhibit a cyclic change.

Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) is a kind of inborn errors of metabolism, with the main clinic manifestations of jaundice, hepatomegaly, and abnormal liver function indices. As a mitochondrial solute carrier protein, citrin plays important roles in aerobic glycolysis, gluconeogenesis, urea cycle, and protein and nucleotide syntheses. Therefore citrin deficiency causes various and complicated metabolic disturbances, such as hypoglycemia, hyperlactic acidemia, hyperammonemia, hypoproteinemia, hyperlipidemia, and galactosemia. This paper reported a case of NICCD confirmed by mutation analysis of SLC25A13, the gene encoding citrin. The baby (male, 6 months old) was referred to the First Affiliated Hospital with the complaint of jaundice of the skin and sclera, which it had suffered from for nearly 6 months. Physical examination showed obvious jaundice and a palpable liver 5 cm below the right subcostal margin. Liver function tests revealed elevated enzymatic activities, like GGT, ALP, AST, and ALT, together with increased levels of TBA, bilirubin (especially conjugated bilirubin), and decreased levels of total protein/albumin and fibrinogen. Blood levels of ammonia, lactate, cholesterol, and triglyceride were also increased, and in particular, the serum AFP level reached 319,225.70 microg/L, a extremely elevated value that has rarely been found in practice before. Tandem mass analysis of a dried blood sample revealed increased levels of free fatty acids and tyrosine, methionine, citrulline, and threonine as well. UP-GC-MS analysis of the urine sample showed elevated galactose and galactitol. The baby was thus diagnosed with suspected NICCD based on the findings. It was then treated with oral arginine and multiple vitamins (including fat-soluble vitamins A, D, E, and K), and was fed with lactose-free and medium-chain fatty acids enriched formula instead of breast feeding. After half a month of treatment, the jaundice disappeared, and the laboratory findings, including liver function indices, blood levels of ammonia, lactate and AFP, were returned to normal level. The baby was followed up for 6 months. It developed well, and the abnormal laboratory findings, including MS-MS and UP-GC-MS analysis results, have been corrected, except a slightly elevated lactate level sometimes. SLC25A13 gene mutation analysis for the patient revealed a compound heterozygote of mutation 851del4 and 1638ins23 and therefore NICCD was definitely diagnosed.
