Objective To evaluate the efficacy and safety of wuling capsule compared with deanxit in treatment of patients with depression or anxiety status. Methods A total of 139 patients with depression or anxiety status were enrolled in a multi-center double blind clinical trial. All patients were randomized into two groups, 67 patients in wuling capsule group and 73 patients in deanxit group. Efficacy and adverse effects were evaluated with Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD),Pittsburgh Sleep Quality Index (PSQI) and Treatment Emergent Symptoms Scale (TESS) before treatment and 1, 2, 4, 6 weeks after treatment to verify the noninferiority of wuling capsule. Results There was no significant difference in score decline of HAMA and HAMD between the two groups (HAMA: wuling vs deanxit group: 9.0 ± 5.4 vs 10.3 ± 5.4, F = 2.11, P =0.148 ; HAMD: wuling vs deanxit: 9.1±5.6 vs 10.5±5.7, F = 1.61, P=0.207). There was no significant difference in response rate and remission rate between the two groups. No significant difference was found in score decline of PSQI between the two groups (wuling vs deanxit group: 4.1±4.5 vs 5.0 ± 4.2, F = 0.72, P=0.192). The incidence of adverse events was 41% in the wuling group and 55% in the deanxit group respectively. The main adverse effects were symptoms of gastrointestinal and neurology system. Conclusion Safe and well tolerated, wuling capsule improves the anxiety, depression and insomnia symptoms of patients with depression or anxiety status.

Objective:To observe the clinical effect of electroacupuncture(EA)combined with exercise therapy on balance function in patients with knee osteoarthritis(KOA). Methods:Seventy patients with KOA were randomly divided into a treatment group and a control group,with 35 cases in each group.The treatment group was treated with EA combined with exercise therapy.EA was applied to Dubi(ST35),Neixiyan(EX-LE4),Xuehai(SP10),Liangqiu(ST34),Yanglingquan(GB34),and Zusanli(ST 36).Exercise therapy(muscle strength training and knee mobility training)was applied after EA.The control group only received the same exercise therapy as the treatment group.The two groups were treated with the same course of treatment,3 times a week for 4 consecutive weeks,12 times in total,and followed up for 1 month.The Pro-Kin254P balance test system was used to measure the balance function parameters at 4 time points,including before treatment,after 1 session of treatment,after 12 sessions of treatment,and at 1-month follow-up after treatment.The visual analog scale(VAS)and the Western Ontario and McMaster Universities osteoarthritis index(WOMAC)scores were recorded. Results:The markedly effective rate and total effective rate in the treatment group were higher than those in the control group(P<0.01).The Romberg area,Romberg length,and VAS scores of the two groups decreased significantly after 1 session of treatment,12 sessions of treatment,and 1 month after treatment,and the differences between different time points in the same group were statistically significant(P<0.01).There were significant differences between the two groups at the same time point(P<0.05).The total WOMAC scores of the two groups after 1 session of treatment,12 sessions of treatment,and 1 month after treatment decreased significantly,and there were significant differences between different time points in the same group(P<0.05),but there was no significant difference between the two groups at the same time point(P>0.05). Conclusion:EA combined with exercise therapy or exercise therapy alone can enhance the balance function,relieve joint pain,and improve joint function in patients with KOA.EA combined with exercise therapy is superior to exercise therapy alone in improving balance function and pain,but the two treatment protocols have similar effects in improving joint function.

OBJECTIVETo study the effects of total alkaloids of Rubus alceaefolius (RAP) on non-alcoholic fatty liver disease (NAFLD) rats and explore its possible mechanisms.

METHODSixty SD rats were randomly divided into six groups: control group, model group, compound methionine and choline bitartrate tablets (CMCB)group and three RAP groups treated respectively with low, middle and high dose of RAP. The NAFLD model was induced by feeding fat-rich food. NAFLD rats were administrated with 0.35 g x kg(-1) CMCB and 0.36, 0.72, 1.44 g x kg(-1) RAP for 4 weeks respectively. The weight index of liver was measured. Hepatic histolog ical changes were observed. The concentration in serum of aspartate amino transferase (AST), alanine amino tranferase (ALT), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) were determined. The mRNA expressions of SOD, MDA, TNF-alpha and IL-6 in hepatic tissue were detected.

RESULTCompared with the model group, degree of steatosis of hepatic lobule was improved, the weight index of liver was decreased, serum levels of ALT, AST, TNF-alpha and IL-6 were significantly lower in the high and middle dose RAP group (P < 0.05 or P < 0.01). The levels of SOD and MDA in hepatic tissue were lower in the high dose RAP group (P < 0.05). The mRNA expressions of TNF-alpha and IL-6 in hepatic tissue were decreased (P < 0.05 or P < 0.01).

CONCLUSIONRAP can protect liver in experimental NAFLD, and its possible mechanisms may be concerned with clearing the oxygen free radical, reducing the product of lipid peroxidation, inhibiting the release of inflammatory cytokines and reducing nflammatory response.

Background and objectiveLung cancer is the leading cause of cancer-related deaths worldwide, and metastasis is the major cause of death in lung cancer patients. MiR-373 is closely associated with invasion and metastasis in other tumor cells. hTis study explored the expression of miR-373-3p in non-small cell lung cancer (NSCLC) and its effect on the invasive and metastatic capabilities of lung adenocarcinoma cells, as well as their mechanisms of action.MethodshTe expression of miR-373-3p in NSCLC tissues and lung adenocarcinoma cell lines was detected by quantitative reverse transcrip-tion polymerase chain reaction. hTe roles of miR-373-3p in regulating lung adenocarcinoma cell invasion and metastatic prop-erties were analyzed with miR-373-3p mimic/inhibitor-transfected cells via Transwell chamber assay. Matrix metalloproteinase MMP-9 and MMP-14 protein levels were detected by Western blot in lung cancer cells atfer transfection.Results MiR-373-3p was upregulated in 51 NSCLC tissues and 5 NSCLC cell lines. Gain-of-function and loss-of-function studies showed that overexpression of miR-373-3p promoted H1299 cell migration and invasion, which resulted in upregulation of MMP-9 and MMP-14. By contrast, miR-373-3p knockdown inhibited these processes in A549 cells and downregulated the expression of MMP-9 and MMP-14.ConclusionOur results demonstrated that miR-373-3p participated in the invasion and metastasis of lung adenocarcinoma cells, partly by upregulation of MMP-9 and MMP-14.
