ABSTRACT

ObjectiveTo observe the effect of Wenyang Jieyu decoction (WYJY) on the hippocampal structure of depressed rats with kidney-yang deficiency. MethodThe 105 SD rats were randomly divided into normal group, model group, fluoxetine group (4.17 mg·kg-1), Xiaoyaosan group (1.88 g·kg-1), and low-, medium- and high-dose (1.25,2.50,5.00 g·kg-1) WYJY groups,15 in each group. The depression model was induced by subcutaneous injection of corticosterone in rats except for those in the normal group and the rats were orally administered once a day for 28 days. The depression-like behaviors of rats were observed by sucrose preference test, novelty-suppressed feeding test, forced swimming test, and open field test. The morphology of hippocampal neurons was observed by hematoxylin-eosin(HE) staining, and the density of hippocampal neurons was detected by Nissl staining. The ultrastructure of hippocampal synapses was observed by transmission electron microscopy (TEM). The expression of synaptophysin (SYP), postsynaptic density-95 (PSD95), and apoptosis-related protein Caspase-3 in hippocampal neurons was observed by immunohistochemistry, and bromodeoxyuridine (BrdU) and doublecortin (DCX) were used to observe the apoptosis and regeneration of hippocampal neurons. ResultWYJY could improve weight loss in depressed rats. As revealed by the behavioral tests, the model group showed depression-like behaviors, which were relieved in the WYJY groups and the positive drug groups. HE staining showed that the nuclei of hippocampal neurons in the model group were constricted, deeply stained, and sparsely arranged, while the neurons in the WYJY groups and the positive drug groups were significantly improved. Nissl staining demonstrated that the cell density of the model group was lower than that of the normal group (P<0.05). Compared with model group, the groups with drug intervention showed increased cell density (P<0.05) and compact arrangement. According to the results in TEM, compared with normal group, the model group showed shortened synaptic active zone (P<0.05), widened synaptic cleft (P<0.05), and thinned tight zone (P<0.05). Compared with model group, the groups with drug intervention showed shortened synaptic active zone (P<0.05), narrowed synaptic cleft (P<0.05), and thickened tight zone (P<0.05). As displayed by the results of immunocytochemistry and immunofluorescence, compared with the normal group, the model group showed decreased protein expression of SYP, PSD95, BrdU, and DCX in the hippocampus (P<0.05) and increased protein expression of Caspase-3 (P<0.05). Compared with the model group, the groups with drug intervention showed increased protein expression of SYP, PSD95, BrdU, and DCX in the hippocampus (P<0.05) and decreased protein expression of Caspase-3 (P<0.05). ConclusionWYJY can promote the regeneration of hippocampal neurons in rats and improve the depression of rats.

ABSTRACT

ObjectiveTo explore the potential anti-tuberculosis mechanism of Kanglao granule through network pharmacology. MethodThe active components of Kanglao granule were retrieved from related databases and the potential targets of the components from SwissTargetPrediction. Targets of the tuberculosis were screened from GeneCards and National Center for Biotechnology Information (NCBI), and the anti-tuberculosis targets of the prescription were further identified. STRING and Cytoscape 3.8.0 were employed to construct the Chinese medicinal-disease target-signaling pathway network and screen core targets. Then gene ontology (GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment were performed. Finally, AutoDock Vina was used for molecular docking between the active components of the prescription and key proteins and Western blotting for verifying the interaction between them. ResultA total of 29 important chemical components in the prescription were screened out, including β-sitosterol, sesamin, and kaempferol. A total of 28 key anti-tuberculosis targets were retrieved, such as protein kinase B1 (Akt1), epidermal growth factor receptor (EGFR), hypoxia inducible factor-1A (HIF-1A), proto-oncogene tyrosine-protein kinase (SRC), and matrix metalloproteinase-9 (MMP-9). Bioinformatics analysis showed the 28 targets were involved in 41 GO terms such as oxygen metabolism, nucleic acid transcription, and metabolic enzyme pathway, and 28 key KEGG pathways, including Mycobacterium tuberculosis signaling pathway and phosphatidylinositol 3 kinase/protein kinase B pathway. Molecular docking results showed that Akt1 had the strongest binding affinity to sesamin. In vitro experiment indicated that sesamin inhibited the growth of M. tuberculosis by suppressing the phosphorylation of Akt1. ConclusionKanglao granule improved the sterilization level and immune response through multi-component, multi-target, and multi-pathway interactions, thereby achieving therapeutic effect on tuberculosis. Akt1 is one of the important targets involved in the treatment of tuberculosis.

ABSTRACT

OBJECTIVE@#To investigate the surgical skills and clinical curative results of arthroscopic treatment of ankle instability combined with anteromedial impingement syndrome.@*METHODS@#From February 2019 to August 2020, 13 patients with ankle instability combined with anteromedial impingement were retrospectively analyzed. There were 10 males and 3 females with age of (40.0±15.1) years old. The course of disease was(44.1±33.2) months. All patients had history of ankle sprain. MRI showed the injury of anterior talofibular ligament. All patients had anteromedial pain and pressing pain when ankle dorsiflexion. All patients were treated with ankle debridement and Brostr?m-Gould surgery under ankle arthroscopic. Postoperative results were evaluated by VAS(visual analogue scale) and AOFAS-AH(American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale, AOFAS-AH).@*RESULTS@#All 13 patients completed the surgery successfully with an operative time of 60 to 90 minutes. All the surgical incisions healed by first intention, and no complications such as incision infection, skin necrosis and neurovascular injury. Follow-up time was (18.1±4.7) months. At the latest follow-up, the VAS score was 1.2±1.1, which was significantly lower than the preoperative score 4.8±1.5 (P<0.05);the AOFAS-AH score 94.2±5.1 was significantly higher than the preoperative score 65.5±11.5 (P<0.05). The AOFAS-AH score at the final follow-up ranged from 84 to 100. All patients walked with normal gait without ankle instability or impingement recurrence.@*CONCLUSION@#Ankle anteromedial impingement syndrome combined with ankle instability is easy to be ignored clinically. Such kind of anteromedial impingement syndrome is mostly related to osteophyte at dorsal medial talar neck. Arthroscopic treatment of ankle instability combined with anteromedial impingement syndrome has satisfactory curative effect with safety and minimal injury.

ABSTRACT

@#To construct PTEN/PLGA-(HE)10-MAP nanoparticles, which encapsulated PTEN plasmid DNA and combined with the pH-responsive cell-penetrating peptides (CPPs), and to investigate their effects of gene delivery and anti-tumor targets in vitro. Poly (lactic-co-glycolic acid) (PLGA) nanoparticles loaded with PTEN plasmid DNA were prepared by double emulsification-solvent evaporation method. PTEN/PLGA-(HE)10-MAP nanoparticles were prepared by coupling the histidine-glutamic acid-model amphipathic peptide nanocomplex [(HE)10-MAP] to the surface through amide condensation reaction. Particle size, Zeta potential, encapsulation rate and drug loading were tested to characterize the nanoparticles. By analyzing the cytotoxicity, cellular uptake, targeted transfection of eukaryotic expression plasmids and anti-tumor cell proliferation, the feasibility as a targeted gene delivery system were evaluated. The particle size of PTEN/PLGA-(HE)10-MAP nanoparticles was (266.5 ± 2.86) nm, with the encapsulation efficiency (80.6 ± 6.11)%. Zeta potentials were -(6.7 ± 0.26) mV, +(0.7 ± 0.22) mV and +(37.5 ± 0.85) mV at pH 7.4, 7.0 and 6.5, respectively. In the cytotoxicity test, the cell survival rates of tumor and normal cells were above 80%.Non-loading PLGA-(HE)10-MAP nanoparticles showed no obvious cytotoxicity. The results of cellular uptake experiments showed that PTEN/PLGA-(HE)10-MAP nanoparticles were more readily taken up by cells.The results of CCK-8 showed that the nanoparticles could pH-specifically inhibit proliferation of tumor cell in vitro.And PTEN/PLGA-(HE)10-MAP nanoparticles may be applied in tumor gene therapy.

ABSTRACT

T-cell acute lymphoblastic leukemia (T-ALL) is derived from the malignant transformation and clonal proliferation of precursor T cells. T-ALL is usually associated with the genetic mutations and/or chromosomal translocation, thus causing the change of survival, proliferation and progenitor cell differentiation of T cells in T-cell development. Studies have shown that Wnt signaling pathway plays a key role in the regulation of hematopoietic stem cell and normal T-cell development, and it is also abnormally altered in T-ALL. This article reviews the research progress of the mechanism of Wnt signaling pathway in T-ALL development.

ABSTRACT

Background and Objectives@#Chronic kidney disease (CKD) has a major impact on the quality of life of patients, and renal fibrosis is a critical pathological change in the disease. It is very important to control the process of renal fibrosis to improve the quality of life of patients with CKD. The pathological mechanism of renal fibrosis is very complicated, and the current treatment strategy also has many flaws. @*Methods@#and Results: To explore a better treatment, we collected exosomes from pluripotent stem cell (PSC)-derived mesenchymal stem cells (MSC) and verified their therapeutic effect on renal fibrosis through In Vivo and In Vitro experiments. In this study, we found that PSC-MSC-derived comes could prevent the epithelial differentiation of NRK-52E cells, and with increasing exosome concentrations, the effect was improved. Furthermore, PSC-MSC-derived exosomes could reduce the pathological process of renal fibrosis, reduce inflammatory reactions and improve renal function in UUO mice. Moreover, the protective effect of exosomes against renal fibrosis may be achieved by increasing the expression of SIRT6 and decreasing the expression of β-catenin and its downstream products. @*Conclusions@#These findings suggest the possibility of PSC-MSC-derived exosomes as a new, effective therapeutic tool for kidney fibrosis.

ABSTRACT

Peritoneal metastasis of gastrointestinal cancer is an independent factor that seriously affects the prognosis of patients. The "seed-soil" theory is considered to be the main theory to explain peritoneal metastasis. Because of the small size of peritoneal metastatic nodules at the initial stage, early diagnosis is particularly difficult, therefore, the risk assessment of peritoneal metastasis is very important. Recently, the diagnosis methods have gradually developed from clinicopathological factors to cytology and molecular level. In addition, the integrated assessment of multiple groups including radiomics further enriches the accurate diagnosis of peritoneal metastasis. Peritoneal metastasis is a big challenge in the treatment of gastrointestinal cancer which may also lead to refractory malignant ascites, intestinal obstruction, cachexia and other related complications. At present, the treatment is based on systemic chemotherapy. The combination of surgery, intraperitoneal chemotherapy and HIPEC is an effective treatment for peritoneal metastasis of gastrointestinal cancer. How to enrich peritoneal metastasis patients with potential benefits, how to determine the timing of conversion surgery, how to further optimize the existing treatment plan, especially how to formulate treatment plan for patients after conversion surgery, call for improved study design and prospective randomized controlled trials. The goal of continuous efforts is to effectively prolong the survival of gastrointestinal cancer trials patients with peritoneal metastasis.

ABSTRACT

OBJECTIVE@#To observe the clinical effect of high suspension and low incision (HSLI) surgery on mixed haemorrhoids, compared with Milligan-Morgan haemorrhoidectomy.@*METHODS@#A multi-centre, randomized, single-blind, non-inferiority clinical trial was performed. Participants with mixed haemorrhoids from Xiyuan Hospital of China Academy of Chinese Medical Sciences, Beijing Rectum Hospital, Air Force Medical Center of People's Liberation Army of China, and Puyang Hospital of Traditional Chinese Medicine were enrolled from September 2016 to March 2018. By using a blocked randomization scheme, participants were assigned to two groups. The experimental group was treated with HSLI, while the control group was treated with Milligan-Morgan haemorrhoidectomy. The primary outcome was the clinical effect evaluated at 12 weeks after operation. The secondary outcomes included the number of haemorrhoids treated during the operation, pain scores, use of analgesics, postoperative oedema, wound healing, incidence of anal stenosis, anorectal manometry after operation, as well as surgical duration, length of stay and total hospitalization expenses. A safety evaluation was also conducted.@*RESULTS@#In total, 246 eligible participants were enrolled, with 123 cases in each group. There was no significant difference in the clinical effect between the two groups (100.00% vs. 99.19%, P>0.05). Compared with the control group, the number of external haemorrhoids treated during the operation and the pain scores after operation were significantly reduced in the experimental group (P0.05). The surgical duration and length of stay in the experimental group were significantly longer than those in the control group, and the total hospitalization expense was significantly higher than that in the control group (all P<0.05). No adverse events were reported in either group during the whole trial or follow-up period.@*CONCLUSION@#HSLI had the advantages of preserving the skin of anal canal completely, alleviating postsurgical pain and promoting rapid recovery after operation.

ABSTRACT

The present study aimed to explore the effect of Erxian Decoction on proteomics of osteoblasts stimulated by hydrogen peroxide(H_2O_2) and its protective mechanism with the H_2O_2-induced cell model of oxidative stress. The primary osteoblasts were cultured from the skulls of newborn rats(within 24 hours) and divided into a control group, a model group, a Fosamax group, and an Erxian Decoction group. Blank serum was added in the control group and model group, and the drug-containing serum was added correspondingly to the remaining two groups. After 45 hours, H_2O_(2 )stimulation was conducted for three hours except for the control group, followed by protein extraction. Nano-LC-LTQ-Orbitrap system was used for protein detection, Protein Discovery for protein identification, and SIEVE for quantitative and qualitative analysis. Furthermore, following the blocking of PI3 K signaling pathway by LY294002(10 μmol·L~(-1)), a control group, a model group, an LY294002 group, an Erxian Decoction group, and an Erxian Decoction + LY294002 group were set up to observe the effect of Erxian Decoction on cell proliferation, alkaline phosphatase(ALP) activity, and the relative expression of BMP-2, OPG, p-Akt, p-FoxO1 of osteoblasts stimulated by H_2O_2 under LY294002 intervention. The results revealed that 78 differential proteins were discovered between the Erxian Decoction group and model group, which were involved in the regulation of PI3 K/Akt, glucagon, estrogen, insulin, and other signaling pathways. LY294002 blunted the promoting effect of Erxian Decoction on osteoblast proliferation and significantly down-regulated the expression of OPG and p-FoxO1, whereas its down-regulation on the expression of BMP-2 and p-Akt was not significant. Both LY294002 and Erxian Decoction increased the ALP activity of osteoblasts, which may be related to the cell state and the cell differentiation. The above results suggest that Erxian Decoction can protect osteoblasts stimulated by H_2O_2, with the PI3 K/Akt signaling pathway as one of the internal mechanisms.

ABSTRACT

Objective:To study the effects of T-2 toxin on expression of fibroblast growth factor 8 (FGF8) and fibroblast growth factor receptor 3 (FGFR3) in articular cartilage and subchondral marrow of rats under low selenium condition, and to explore the mechanism of deep cartilage injury and secondary complications in Kaschin-Beck disease (KBD).Methods:Twenty-four healthy male SD rats weighted 60 - 80 g were selected, they were divided into conventional feed group (selenium content of 101.5 μg/kg) and low-selenium feed group (selenium content of 1.1 μg/kg) by random number table method, with 12 rats in each group. After 30 days of feeding, the conventional feed group was further divided into control group and T-2 toxin group (100 μg·kg -1·d -1), and the low-selenium feed group was further divided into low-selenium group and low-selenium+ T-2 toxin group, with 6 rats in each group. After 30 days of feeding, the rats were sacrificed and the knee cartilage with cancellous bone was taken. Pathological changes of knee cartilage were observed by HE staining. Immunohistochemical method was used to detect the expression of FGF8 and FGFR3 in cartilage and subchondral marrow of knee joint, positive expression rates of FGF8 and FGFR3 in articular cartilage were calculated, and the integrated optical density (IOD) values of FGF8 and FGFR3 positive expression in subchondral marrow were analyzed by Image-Pro Plus 6.0 software. Results:Under light microscope, chondrocytes in low-selenium+ T-2 toxin group were sparse, and empty chondrocytes in the deep and middle layers of articular cartilage increased, and chondrocytes died and became red cell shadows. The extracellular matrix dissolved and was slightly stained in deep region, turning into necrotic and unstructurized areas. Proliferating granulation tissue was visible nearby. The positive expression rate of FGF8 in articular cartilage of rats in low-selenium+ T-2 toxin group [(88.61 ± 10.97)%] was higher than that in control, low-selenium and T-2 toxin groups [(10.35 ± 2.48)%, (19.26 ± 3.08)%, (58.89 ± 9.29)%, P < 0.05]; IOD value of FGF8 positive expression in subchondral marrow [(16.73 ± 1.72) × 10 6] was higher than that in control, low-selenium and T-2 toxin groups [(1.20 ± 0.41) × 10 6, (4.33 ± 0.97) × 10 6, (12.80 ± 1.12) × 10 6, P < 0.05]. The positive expression rate of FGFR3 in articular cartilage of rats in low-selenium+ T-2 toxin group [(89.76 ± 8.59)%] was higher than that in control, low-selenium and T-2 toxin groups [(13.18 ± 2.25)%, (21.15 ± 2.33)%, (32.55 ± 6.72)%, P < 0.05]; IOD value of FGFR3 positive expression in subchondral marrow [(16.50 ± 5.36) × 10 6] was higher than that in control, low-selenium and T-2 toxin groups [(7.58 ± 1.02) × 10 6, (10.73 ± 7.13) × 10 6, (9.83 ± 5.63) × 10 6, P < 0.05]. Conclusion:Under low selenium condition, T-2 toxin changes expression of FGF8 and FGFR3 in deep chondrocytes of articular cartilage and subchondral marrow in rats, elevated expression of FGF8 and FGFR3 may be involved in the occurrence and development of secondary changes in KBD.

Methods: A total of 123 IBS-D patients were divided into an observation group, a Western medication group and an integrated Western and Chinese medication group using the random number table method, with 41 cases in each group. The Western medication group was given oral pinaverium bromide, 50 mg each time and 3 times a day. The integrated Western and Chinese medication group was given additional Chinese herbal medicine Tong Xie Yao Fang, one dose each day. The observation group was given additional intradermal needle therapy on the basis of the Western medication group. The whole intervention lasted for 6 weeks. Before and after treatment, the scores of gastrointestinal symptoms, traditional Chinese medicine (TCM) symptoms, irritable bowel syndrome (IBS) symptom severity scale (IBS-SSS) and IBS quality of life (IBS-QOL) questionnaire, as well as the serum levels of 5-HT, SP and VIP were observed. The clinical efficacy was estimated. Results: The total effective rate was 92.7% in the observation group, 68.3% in the Western medication group and 78.1% in the integrated Western and Chinese medication group. The total effective rate was higher in the observation group than in the other two groups, and higher in the integrated Western and Chinese medication group than in the Western medication group, showing statistical significance (all P<0.05). After treatment, the scores of gastrointestinal symptoms, TCM symptoms and IBS-SSS showed significant decreases in the three groups, presenting statistical significance compared with the baseline (all P<0.05); the scores of gastrointestinal symptoms, TCM symptoms and IBS-SSS were notably lower in the observation group than in the other two groups (all P<0.05), and lower in the integrated Western and Chinese medication group than in the Western medication group (all P<0.05). After treatment, the eight component scores of IBS-QOL showed significant increases in the three groups compared with the baseline (all P<0.05); the eight component scores in IBS-QOL were significantly higher in the observation group than in the other two groups (all P<0.05), and higher in the integrated Western and Chinese medication group than in the Western medication group (all P<0.05). After treatment, the serum levels of 5-HT, SP and VIP decreased markedly in the three groups compared with the baseline (all P<0.05); the serum levels of 5-HT, SP and VIP were significantly lower in the observation group than in the other two groups (all P<0.05), and lower in the integrated Western and Chinese medication group than in the Western medication group (P<0.05). Conclusion: Treatment with intradermal needle therapy plus pinaverium bromide results in significant improvements in the gastrointestinal symptoms and quality of life in patients with IBS-D of liver-qi stagnation and spleen deficiency pattern, and effectively regulates the gastrointestinal hormone production.

ABSTRACT

Objective:To investigate the protective effects of Elabela(ELA) on the renal injury of db/db mice and its possible mechanism.Methods:Sixteen eight-week-old male db/db mice were intraperitoneally injected with ELA(5 mg·kg -1·day -1) or equivalent normal saline( n=8) for 8 weeks. Eight age-matched male db/m mice received equivalent normal saline injection as normal control. At the end of the experiment, blood and urine samples were obtained for HbA 1C and urinary albumin/creatinine(ACR) measurements. Immunohistochemistry was used to observe the expression of ELA. Histopathological changes in kidney tissue were observed by HE staining and Masson staining. The levels of collagen type Ⅳ(Col-Ⅳ) and transforming growth factor-β1(TGF-β1) as well as Yes-associated protein(YAP) phosphorylation in kidney tissue were examined by western blot. Results:Immunohistochemistry results showed that ELA expression was decreased in the renal tissue of db/db mice as compared with that of db/m mice( P<0.05). After ELA treatment, ACR and blood pressure were markedly decreased in db/db mice( P<0.05), but without significant changes in the body weight and HbA 1C. Renal tubular epithelial cells edema, basement membrane thickening, and increased collagen fiber in db/db were improved by ELA administration. Compared with db/m mice, the levels of TGF-β1 and Col-Ⅳ expression, as well as YAP phosphorylation were significantly increased in renal tissue of db/db mice(0.98±0.08 vs 0.68±0.10, 1.10±0.14 vs 0.51±0.08, 3.38±0.72 vs 0.81±0.13, all P<0.05), which were down-regulated after ELA administration(0.80±0.06, 0.51±0.05, 2.21±0.22, all P<0.05). Conclusion:ELA may improve the renal injury of db/db mice by regulating the signaling pathway of YAP, thereby delaying the development of diabetic nephropathy.

ABSTRACT

OBJECTIVE@#To explore the clinical therapeutic effect of herb-partitioned moxibustion at point in patients of diabetic gastroparesis differentiated as spleen and stomach deficiency and retention of turbid dampness as well as its effect mechanism.@*METHODS@#A total of 134 patients with diabetic gastroparesis were randomized into an observation group and a control group, 67 cases in each one. In the observation group, herb-partitioned moxibustion at point was adopted, 40 min each time, once a day for 5 times a week. In the control group, itopride hydrochloride tablets were prescribed for oral administration, 50 mg each time, three times a day. A total of 6 weeks of treatment was required in the two groups. Before and after treatment, the gastroparesis cardinal symptom index (GCSI) scores, 4-hour gastric emptying rate, TCM symptom score, as well as the levels of plasma motilin and serum gastrin were observed in the patients of the two groups. Additionally, the clinical therapeutic effect was evaluated in the two groups.@*RESULTS@#After treatment, the score of every item of GCSI, TCM symptom scores and the levels of plasma motilin and serum gastrin were all reduced as compared with those before treatment in the patients of the two groups (<0.05), and those in the observation group were lower than the control group (<0.05). Regarding 4-hour gastric emptying rates, which were increased as compared with those before treatment in the two group (<0.05), and the rate in the observation group was higher remarkably than that in the control group (<0.05). The total effective rate was 92.5% (62/67) in the observation group, higher than 74.6% (50/67) in the control group (<0.05).@*CONCLUSION@#Herb-partitioned moxibustion at point relieves the clinical symptoms in the patients with diabetic gastroparesis and increases the gastric emptying rate, which is probably related to the regulation of the levels of plasma motilin and serum gastrin.

ABSTRACT

OBJECTIVE@#To observe the clinical therapeutic effect of herb-separated moxibustion at Jinsuo (GV 8)- eight-diagram points on diarrhea-type irritable bowel syndrome (IBS-D) of liver stagnation and spleen deficiency as compared with oral administration of pinaverium bromide tablets and Chinese herbal decoction, .@*METHODS@#A total of 126 patients with IBS-D of liver stagnation and spleen deficiency were randomized into a herb-separated moxibustion group (moxibustion group), a western medication group and a Chinese herbal medication group, 42 cases in each one. In the moxibustion group, the herb-separated moxibustion was applied to Jinsuo (GV 8)-eight-diagram points. The herbs in (fried , fried , and ) were ground into herbal paste and the paste was put on Jinsuo (GV 8)-eight-diagram points. The suspending moxibustion was exerted over the points for 40 min, once daily. In the western medication group, pinaverium bromide tablets were taken orally, 50 mg each time, three times a day. In the Chinese herbal medication group, the decoction of was taken orally, one dose a day, taking separately in two times. The duration of treatment was 8 weeks in each group. Before and after treatment, the symptom score of traditional Chinese medicine (TCM), gastrointestinal (GI) symptom score, the score of IBS symptom severity scale (IBS-SSS) and the score of IBS quality of life (IBS-QOL) scale were observed in patients of each group separately. The clinical therapeutic effect was evaluated.@*RESULTS@#After treatment, the scores of TCM symptoms, GI symptom scores and IBS-SSS scores were all obviously reduced in each group (<0.05). Each of the scores in the moxibustion group was lower than the western medication group and the Chinese herbal medication group respectively (<0.05). After treatment, the scores of each of eight subscale structures of IBS-QOL scale, named dysphoria, interference with activity, body image, health worry, food avoidance, social reaction, sexual intercourse and relationship, were all increased obviously in each group (<0.05). The scores of each of eight subscale structures in the moxibustion group were higher than the western medication group and the Chinese herbal medication group respectively (<0.05). The total effective rate was 92.9% (39/42) in the moxibustion group, higher than 71.4% (30/42) in the western medication group and 73.8% (31/42) in the Chinese herbal medication group respectively (<0.05).@*CONCLUSION@#Herb-separated moxibustion at Jinsuo (GV 8)-eight-diagram points remarkably relieves gastrointestinal symptoms and improves the quality of life in patients of diarrhea-type irritable bowel syndrome of liver stagnation and spleen deficiency, and its clinical therapeutic effect is superior to oral administration of either pinaverium bromide tablets or .

ABSTRACT

OBJECTIVE:To investigate the effects and its mechanism of pseudostrychnine on the apoptosis of human colon can - cer HT- 29 cells. METHODS :Human colon cancer HT- 29 cells were randomly divided into blank group ,pseudostrychnine low-dose,medium-dose and high-dose groups (125,250,500 μmol/L). They were cultured with culture medium without medicine or relevant concentration of pseudostrychnine for 48 h. The cell apoptosis and mitochondrial transmembrane potential were detected by flow cytometry. Western blotting assay was employed to detect the protein expression of P 53,Caspase-3,Caspase-9,DNA re - pair enzyme from rabbit (c-PARP)and Bcl- 2. RESULTS :Compared with blank group ,apoptotic rate of cells was increased signifi - cantly in pseudostrychnine low-dose ,medium-dose and high-dose groups ,while mitochondrial transmembrane potential was de - creased significantly (P<0.01),in concentration-dependent manner. The protein expression levels of P 53,Caspase-3,Caspase-9 and c-PARP were increased in pseudostrychnine medium-dose and high-dose groups ,compared with blank group ;while those of Bcl-2 were decreased significantly in pseudostrychnine low-dose ,medium-dose and high-dose groups (P<0.05 or P<0.01). CON - CLUSIONS:Pseudostrychnine may change mitochondrial membrane potential by up-regulating the protein expression of P 53 and down-regulating the protein expression of Bcl- 2,and activate the expression of Caspase- 3,c-PARP and Caspase- 9,so as to acti - vate endogenous mitochondrial pathway and promote the apoptosis of HT- 29 cells.

ABSTRACT

Objective@#Investigate the clinicopathological features for secretory carcinoma of breast (SCB).@*Methods@#The clinical data of 3 SCB cases were collected, immunohistochemical staining was performed by the streptavidin-peroxidase (SP) method to test the expression of the antibodies: ER, PR, HER-2, Ki-67, S100, CK5/6, p63, SMA, calponin, GCDFP-15, and EGFR. Fluorescence in situ hybridization (FISH) was used to detect the ETV6-NTRK3 gene fusion.@*Results@#ER was focal weakly positive in case 1 and case 2 (about 5%) , and negative in case 3. PR was focal weakly positive in case 1 (about 5%) and completely negative in case 2 and case 3. Three cases showed that HER-2, SMA, calponin, GCDFP-15 were negative, while S100, CK5/6, EGFR were diffuse strongly positive. The proliferation index was nearly 15% in case 1 and case 2, and 10% in case 3. p63 was negative in mostly tumor cells of case 1, and focal positive expression in the nucleus and cytoplasm. In case 2, p63 was completely negative. However, p63 was observed positive in the cytoplasm as well as some secretory material in case 3. ETV6-NTRK3 gene fusion detection by FISH was positive in all cases.@*Conclusions@#SCB is a rare low grade triple-negative breast cancer with the unique pathomorphologic features, while its recurrent t (12; 15) (p13; q25) translocation resulting in ETV6 -NTRK3 gene fusion. It has the indolent clinical behavior and good prognosis.

ABSTRACT

Objective@#To investigate the clinical value of combined detection of serum angiopoietin 2 (Ang-2) and Clara cell protein 16 (CC16) in the early diagnosis of acute respiratory distress syndrome (ARDS).@*Methods@#Two hundred critical patients, treated at the Department of Critical Care Medicine, Bao'an District People's Hospital, Shenzhen during March 2015 and September 2016,were included in the study. According to the Berlin standard, patients were divided into two groups (n=100 each group): the ARDS group and non-ARDS group.The serum levels of Ang-2 and CC16 were measured by enzyme-linked immunosorbent assay (ELISA) on the first and second day of admission for each patient, in addition to completing APACHEⅡ score, medical history, vital signs collection and other biochemical indicators detection. Finally, paired-samples t test was used to analyze the data. The multiple ROC curve was used to calculate the area under the curve of the reference index of the serum levels of Ang-2 and CC16 on the first and second day.@*Results@#On the first and second day, the serum levels of Ang-2 and CC16 were significantly higher in ARDS patients than those in non-ARDS patients, and there was a correlation between the serum levels of Ang-2 and CC16 in ARDS patients. The ROC curve showed that the combined detection of Ang-2 and CC16 on the first day achieved a highest sensitivity of 75.9% and detection of CC16 on the first day achieved a highest specificity of 70.2%.@*Conclusion@#Single-detection of serum levels of Ang-2 and CC16 could be used for early diagnosis of ARDS, and the combined detection of both has a higher sensitivity than single detection.
