Application and progress of palliative therapy in advanced gastric carcinomas.

Gastric carcinomas have high morbidity and mortality. It produces no noticeable symptoms in the early stage while causing complex complications in its advanced stage, making treatment difficult. Palliative therapy aims to relieve the symptoms of cancer patients and focuses on improving their quality of life. At present, five palliative therapies for advanced gastric carcinomas are offered: resection, gastrojejunostomy, stenting, chemotherapy, and radiotherapy. In recent years, palliative therapy has been used in the clinical treatment of advanced gastric carcinomas and related complications because of its efficacy in gastric outlet obstruction and gastric bleeding. In the future, multimodal and interdisciplinary palliative therapies can be applied to control general symptoms to improve patients' condition, prolong their lifespan and improve their quality of life.

Treatment of Psoriasis Vulgaris with Medicated Thread Moxibustion of Zhuang Medicine: A Multicenter Randomized, Parallel Controlled Trial.

OBJECTIVE: To explore the efficacy and safety of Zhuang medicine medicated thread moxibustion (ZMTM) on psoriasis vulgaris. METHODS: A multicenter, randomized, parallel controlled clinical trial was designed. A total of 241 outpatients with psoriasis vulgaris were randomly divided into a control group (120 cases) and a treatment group (121 cases) using a central block randomization from June 2015 to May 2018. The control group was treated with Western medicines alone including pidotimod dispersible tablets, vitamin B compound tablets, and compound cod liver oil-zinc oxide ointment. The treatment group was treated with ZMTM every 2 days combined with Western medicines. The two groups received continuous intervention for 30 days. The primary outcome was Psoriasis Area and Severity Index (PASI), and the secondary outcomes included Itch Rating Scale, Dermatology Quality of Life Index (DLQI), Hamilton Anxiety Rating Scale (HAMA), as well as PASI response rate. Meanwhile, adverse events were evaluated during the whole clinical trial. Follow-up was carried out 30 days after treatment. RESULTS: There were 5 cases of shedding in this trial. In intention-to-treat analysis, 236 cases were included and each group contained 118 cases. On the 30th and 60th days, PASI scores of patients in each group were significantly lower than that at baseline (P<0.01) and the PASI score reduction of the treatment group was greater than that of the control group (P<0.01). Itch Rating Scale, DLQI, and HAMA scale were decreased in both groups after treatment, and the treatment group showed a better therapeutic effect (P<0.01). The response rates of PASI 50 and 75 were significantly higher than those in the control group [81.4% (96/118), 43.2% (51/118) vs. 41.5% (49/118), 11.0% (13/118), respectively, P<0.05]. During follow-up, the improvements in scores of PASI, Itch Rating Scale, DLQI, and HAMA of the treatment group were significantly greater than those of the control group (P<0.01). The response rates of PASI 50 and 75 in the treatment group were significantly higher than those in the control group, respectively (both P<0.05). No obvious adverse reaction was found in either group. CONCLUSION: ZMTM combined with Western medicines showed a better therapeutic effect in the treatment of psoriasis vulgaris without obvious adverse reaction.

LncRNA AFAP1-AS1/miR-27b-3p/VEGF-C axis modulates stemness characteristics in cervical cancer cells.

BACKGROUND: Long non-coding RNA (lncRNA) actin filament-associated protein 1 antisense RNA 1 (AFAP1-AS1) functions as a competing endogenous RNA to regulate target genes expression by sponging microRNAs (miRs) to play cancer-promoting roles in cancer stem cells. However, the regulatory mechanism of AFAP1-AS1 in cervical cancer (CC) stem cells is unknown. The present study aimed to provide a new therapeutic target for the clinical treatment of CC. METHODS: Hyaluronic acid receptor cluster of differentiation 44 variant exon 6 (CD44v6)(+) CC cells were isolated by flow cytometry (FCM). Small interfering RNAs of AFAP1-AS1 (siAFAP1-AS1) were transfected into the (CD44v6)(+) cells. The levels of AFAP1-AS1 were measured by quantitative real-time PCR (qRT-PCR). Sphere formation assay, cell cycle analysis, and Western blotting were used to detect the effect of siAFAP1-AS1. RNA pull-down and luciferase reporter assay were used to verify the relationship between miR-27b-3p and AFAP1-AS1 or vascular endothelial growth factor (VEGF)-C. RESULTS: CD44v6(+) CC cells had remarkable stemness and a high level of AFAP1-AS1. However, AFAP1-AS1 knockdown with siAFAP1-AS1 suppressed the cell cycle transition of G(1)/S phase and inhibited self-renewal of CD44v6(+) CC cells, the levels of the stemness markers octamer-binding transcription factor 4 (OCT4), osteopontin (OPN), and cluster of differentiation 133 (CD133), and the epithelial-mesenchymal transition (EMT)-related proteins Twist1, matrix metalloprotease (MMP)-9, and VEGF-C. In the mechanism study, miR-27b-3p/VEGF-C signaling was demonstrated to be a key downstream of AFAP1-AS1 in the CD44v6(+) CC cells. CONCLUSIONS: LncRNA AFAP1-AS1 knockdown inhibits the CC cell stemness by upregulating miR-27b-3p to suppress VEGF-C.

[Effects of Longzuan Tongbi Recipe on Fas/FasL Systems in Serum and Synovium of Collagen-in- duced Arthritis Rats].

Objective To observe the effect of Longzuan Tongbi Recipe (LTR) on Fas/FasL sys- tems in serum and synovium of collagen-induced arthritis (CIA) rats. Methods Ten rats were randomly selected from 60 male Wistar rats as a normal control group. CIA model was prepared by injecting type II bovine collagen and incomplete Freund's adjuvant mixture in the rest 50 rats. After modeling rats were di- vided into the model group, the methotrexate (MTX) group, high, middle, and low dose LTR groups, 10 in each group. Normal saline was administered to rats in the model group by gastrogavage. MTX solution (0.27 mg/100 g) was administered to rats in the MTX group by gastrogavage, once per week for 4 succes- sive weeks. LTR (4.32, 2.16, 1.08 g/mL) was administered to rats in the 3 LTR groups by gastrogavage, twice per day for 30 successive days. Morphological changes of synovium were observed by HE staining. Expression levels of Fas/FasL in rat serum and synovium were quantitatively detected by ELISA. Results Normal synovium cells could be seen in the normal group. But they were obviously proliferated, fat cells in the lower synovium were reduced or deformed, fibroblasts were increased in the model group, accompa- nied with infiltration of lymphocytes and monocytes. All these changes were more obviously alleviated in the MTX group, and the 3 LTR groups. Compared withI the normal control group, Fas expression level in- creased in rat serum and synovium, serum FasL expression level decreased in the model group (P <0. 05, P <0. 01). Compared with the model group, Fas expression level decreased in rat serum and synovium in the MTX group, high and middle dose LTR groups; Fas expression level in rat serum increased in the MTX group and 3 LTR groups; Fas expression level in synovium increased in the MTX group, high and middle dose LTR groups (P <0. 05, P <0. 01). Compared with the MTX group, Fas expression level in serum of the low dose LTR group, and Fas expression level in synovium of low and middle dose LTR groups was elevat- ed; Fas expression level in serum and synovium of the high dose LTR group was reduced; FasL expres- sion level in serum and synovium of low and middle dose LTR groups was reduced; FasL expression level in serum and synovium increased of the high dose LTR group (P <0. 05, P <0. 01). Conclusion LTR could control and treat rheumatoid arthritis, and its mechanism might lie in regulating. Fas/FasL systems media- ted cell apoptosis, and relieving pathological reaction of rheumatoid arthritis.
