Purpose To determine the effect of RNase MC2 purified from momordica charantia on cell growth of hepatocellular carcino-ma ( HCC) and its underlying mechanism. Methods MTT, colony formation and nude mice model were used to examine the activity of RNase MC2 in cell proliferation. Cell cycle analysis was done by flow cytometry. Autophagy induced by RNase MC2 treatment was observed via transmission electron microscope. Western blot was performed to detect the RNase MC2-mediated changes of proteins. Re-sults In vitro and in vivo data showed that RNase MC2 markedly inhibited HCC cell proliferation, arrested cells at G2/M phase by in-creasing expression of p53 and p21, induced autophagy via upregulating Beclin-1 and LC3-Ⅱ. Furthermore, combination of RNase MC2 and Sorafenib exerted enhanced lethal effect on HCC cells. Conclusion RNase MC2 manifests significant antitumor activities and enhances the killing effect of Sorafenib in HCC via inducing cell cycle arrest and autophagy.

Objective:To study the mechanism of moxibustion therapy on diabetic peripheral neuropathy for the peripheral neuroprotection.Methods:The DPN model was induced by intraperitoneal injection with streptozotocin (STZ).The rats were given moxibustion at the acupoint Yishu (Extra) and the acupoint Zusanli (ST 36).The treatment was carried out once a day and 15 minutes per acupoint,lasting for 56 d in total.The clinical effect of moxibustion was evaluated by detecting blood sugar,urine sugar,body weight and dietary intakes,as well as nerve conduction velocity with neuroelectrophysiological method.The structure variation of sciatic nerve was observed by HE staining and light microscopy,and the level of NGF in the sciatic nerve Was determined by ELISA.Results:Compared with the model group,the plasma glucose was significantly lower in the moxibustion group (P＜0.01),with significantly faster nerve conduction velocity (P＜0.01),more notably changes in pathological appearance (P＜0.01) and higher level of nerve growth factor (NGF)(P＜0.01).Conclusion:Moxibustion could improve the symptom and signs of peripheral neuropathy in rat models with DPN,which may relate to the increased NGF and enhanced peripheral nerve protection.

Primary biliary cholangitis (PBC) is a chronic cholestatic autoimmune disease and may progress to liver fibrosis, liver cirrhosis, and even end-stage liver disease without timely and effective treatment. The main purpose of PBC treatment is to prevent the development of end-stage liver disease and improve related clinical symptoms and quality of life. Timely and accurate risk stratification may bring benefits to patients with refractory PBC, and an accurate evaluation of the prognosis of PBC patients is of vial importance for clinical treatment. This article reviews the research advances in the prognostic factors for PBC from the aspects of host factors, laboratory examination, and pharmacotherapy.

OBJECTIVETo study the mechanism of Fuzheng Huayu (FZHY) recipe against pulmonary fibrosis relating to MMP-2 activity and type IV collagen expression at lung tissue.

METHODThe pulmonary fibrosis model was induced by intratracheal instillation with bleomycin once in rats. The models were divided into 3 groups: model control, FZHY recipe treated, and methylprednisolone (Solu-Medrol) treated group, each group was of 14 model rats. Normal control group with 10 rats was intoxicated with the same amount of saline. From the second day of intoxication, FZHY recipe treated group orally took FZHY recipe at the dosage of 4.6 g x kg(-1) rat wt, methylprednisolone treated group received intraperitoneal injection with 15 mg x kg(-1) rat wt of methylprednisolone, while model and normal controls took the same volume of saline, 1 time each day and lasting for 4 weeks. Lung and body weights were weighed and the lung/body ratio was calculated. Collagens deposition was check with Masson stain, and lung hydroxyproline (Hyp) content was assayed with Jamall's method. Protein expressions of MMP-2/9 and type IV collagen at lung tissue were analyzed with Western blot and of MMP-2/9 activities by gelatin zymography.

RESULTCompared to normal rats, the model control rats had a high lung/body ratio, remarkable collagen deposition, increased Hyp content and the expressions of type IV collagen, MMP-2 and MMP-9 protein at lung tissue, increased MMP-2 activity, in particular active MMP-2 activity, but decreased MMP-9 activity. Compared to model control, FZHY recipe and methylprednisolone obviously attenuated pulmonary collagen deposition, decreased lung/body ratio and Hyp content, downregulated MMP-2 protein expression and activity, in particular active MMP-2 activity, and FZHU recipe had some better actions than methylprednisolone on lung/body ratio, type IV collagen expression and active MMP-2 activity. But both drug groups had no influence on MMP-9 protein expression and activity.

CONCLUSIONFZHY recipe has a good action against experimental pulmonary fibrosis and its mechanisms are associated with the inhibition of MMP-2 protein and activity, and with the inhibition of over expression of type IV collagen at lung tissue.

OBJECTIVETo assess the clinical efficacy of Xiaozhang Recipe (XR) in treatment of chronic viral hepatitis B patients with compensated liver cirrhosis.

METHODSBased on the anti-viral effects of lamivudine, 84 chronic viral hepatitis B patients with compensated liver cirrhosis were randomly assigned to the treatment group and the control group. Patients in the treatment group were treated with XR (consisting of heterophylla falsestarwort root, large head atractylodes rhizome, tangerine peel, green tangerine peel, water-plantain tuber, bugleweed herb, turtle shell, oyster shell, chicken's gizzard-skin endothelium, areca peel, decocted, one dose daily, twice daily). Patients in the control group took Fuzheng Huayu Capsule (consisting of red sage root, walnut seed, gynostemma pentaphyllum, aweto, magnoliavine fruit; five pills each time, three times daily, 30 min before meals). The therapeutic course for all was 12 months. The changes of the Chinese medicine symptom scores, chronic liver disease questionnaire (CLDQ), the liver function, hepatitis B virus deoxyribonucleic acid (HBV DNA) were compared between before and after treatment in the two groups. Meanwhile, B ultrasound was performed on all patients. Changes of the inner diameter of the portal vein and the splenic vein, the length and the thickness of the spleen were recorded.

RESULTSAfter treatment the Chinese medicine symptom scores and CLDQ obviously decreased in the two groups (P<0.01). Besides, the score in the treatment group decreased more obviously than that in the control group (P<0.05, P<0.01). The Child-Pugh scores obviously decreased in the two groups (P<0.01). However, the comparison between the two groups did not show any statistical significance (P>0.05). The liver function of of the two groups were improved when compared with before treatment (P<0.01), and the treatment group was superior to the control group (P<0.01). The B ultrasound results showed MPV, SPV, the length and the thickness of the spleen obviously decreased in the treatment group (P< 0.01). Only the thickness of the spleen obviously decreased in the control group (P<0.01). The HBV DNA obviously decreased in the two groups (P<0.01), more obviously shown in the treatment group (P<0.01).

CONCLUSIONSXR in combination of lamivudine could improve the liver function of chronic viral hepatitis B patients with compensated liver cirrhosis and HBV DNA, lower their Chinese medicine symptom scores and CLDQ scores, improve their Child-Pugh classification to some extent. It showed favorable effects.

OBJECTIVETo investigate the effects of Fuzheng Huayu recipe and Huangqi tang on DMN-induced experimental liver cirrhosis in rats and explore the therapeutic characteristics of Buxu herbals on liver cirrhosis.

METHODLiver cirrhosis in rats was induced by intraperitoneally injection of DMN for 4 weeks. Cirrhotic rats were randomly divided into 4 groups: model group, and Fuzheng Huayu recipe group, Huangqi tang group, Fuzheng Huayu recipe combined with Huangqi Tang group. The rats in treatment groups were orally administered with Fuzheng Huayu recipe, Huangqi tang, Fuzheng Huayu recipe combined with Huangqi tang (1:1), respectively. Normal and model control rats were given the equivalent normal saline. The body weight, liver weight and spleen weight were observed when rats were sacrificed. Liver histology was examined by HE staining and Sirius red staining. The liver function parameters including ALT, T. Bil and Alb were determined. The SOD activity and MDA content in liver tissues were also measured. Hepatic hydroxyproline (Hyp) content was determined by Jamall's method. The expression of alpha-SMA was determined by both immunohistochemistry staining and western blot method.

RESULTCompared with normal rats, the serum ALT and T. Bil levels in model rats increased obviously, by contrast, the serum Alb level decreased. There was a significant decline of SOD activity in model rat liver tissue, while the content of MDA and Hyp increased remarkably. A severe deterioration of liver architecture, infiltration of inflammatory cells and deposition of collagen were observed in model rat liver tissue. The expression of alpha-SMA also increased significantly. Compared with model rats, the liver function, lipid peroxidation parameters, Hyp content and liver histology were all improved in the 3 treatment groups. The combined group is better than any single-use group in decreasing collagen deposition and expression of alpha-SMA.

CONCLUSIONFuzheng Huayu recipe, Huangqi tang, Fuzheng Huayu recipe combined with Huangqi tang can attenuate liver fibrosis in DMN induced rats. Fuzheng Huayu recipe combined with Huangqi tang is better than that using alone in decreasing collagen deposition. The mechanism is partially due to the better effect of Fuzheng Huayu recipe combined with Huangqi tang on inhibiting activated HSC.

OBJECTIVETo develop a Chinese version of Vertigo Symptom Scale (VSS-C) and to examine its reliability and validity.

METHODSThe VSS was translated into Chinese and developed a Chinese version VSS (VSS-C) with the consent of the author. The VSS-C scale was tested in 52 subjects with cervical spondylosis of vertebral artery type (CSA group) and 21 healthy subjects (control group). In CSA group VSS-C scale and SF-36 scale investigation was performed for 2 times with 1 week interval, after receiving 1-week orthopedic rehabilitation the patients were evaluated with the VSS-C and SF-36 scale; while subjects in control group received the investigation twice in two weeks. The reliability of the scale was evaluated with Cronbach's alpha method and the correlation between SF-36 scale and the VSS-C were also evaluated for the validity.

RESULTSThe internal consistency of VSS-C was good with Cronbach's alpha of 0.886. Test-retest reliability was also very good with an intraclass correlation coefficient (ICC) between two time points, being 0.970 for VSS-C, 0.965 for VSS-AA and 0.992 for the VSS-VER. Regarding concurrent validity, significant low correlation was found between the VSS-AA and VSS-VER (r=0.379, P<0.05). Significant expected correlation was detected between the VSS-C and SF-36 (r>0.5, P<0.05) . The independent-samples t test results (t=6.261, P<0.01) of the CSA group and the control group showed that the VSS-C was able to distinguish healthy people from CSA patients. The paired-samples t test results (t=5.513, P<0.01) showed that VSS-C reflected the improvement of patients after treatment of Chinese massage manipulation.

CONCLUSIONThe Chinese version of VSS has a high comprehensibility, internal consistency and validity, and it can be a useful instrument for evaluation of patients with cervical spondylosis of vertebral artery type in China.

Objective:To re-evaluate the intervention effect of Kuijietong（KJT） on ulcerative colitis（UC）. Method:Sixty patients with mild-to-moderate UC in the active stage were enrolled and randomized into a KJT group （n=30） and a sulfasalazine （SASP） group （n=30）. Patients in the KJT group were treated with KJT granules， one bag divided in two daily doses， once in the morning and once in the evening， while those in the SASP group received SASP， 1 g per time， four times per day. Then the clinical efficacy was evaluated. Result:According to the modified Mayo score，the clinical remission rates of the KJT group and SASP group were determined to be 46.7% （14/30）and 40% （12/30），exhibiting no significant difference between the two groups （P>0.05）. The clinical effective rate of the KJT group was 83.3% （25/30），which was better than 60% （18/30） of the SASP group （P<0.05）. The mucosal healing rate in the KJT group was 36.7% （11/30）， not significantly different from 30% （9/30） in the SASP group. In the alleviation of UC symptoms，the score of large intestine dampness heat syndrome in the KJT group was remarkably better than that in the SASP group （P<0.05），but there was no significant difference in inflammatory bowel disease questionnaire （IBDQ） score between the two groups. In terms of physical and chemical indexes，serum erythrocyte sedimentation rate （ESR） in the KJT group after intervention was lower than that in the SASP group （P<0.05），whereas the interleukin-10 （IL-10） level was higher（P<0.05）. The comparison between the two groups revealed no significant difference in C-reactive protein （CRP）， tumor necrosis factor-α （TNF-α）， CD4⁺ T cells and regulatory T （Treg） cells after intervention. During the intervention，no obvious adverse reactions were found in the two groups，indicating good safety. Conclusion:KJT is not inferior to SASP in relieving mild-to-moderate UC in the active stage.

OBJECTIVE: To explore the clinical efficacy and safety of manual therapy combined with posterior percutaneous endoscopic cervical decompression(PECD) in the treatment of intractable cervical spondylotic radiculopathy. METHODS: From May 2016 to May 2018, 23 CSR patients who responded poorly to conservative treatment for at least 6 weeks underwent the combination management. Firstly, the patients received the posterior percutaneous endoscopic cervical decompression routine care for the following 4 weeks and manual therapy for another 4 weeks. A total of 23 patients were followed up, including 14 males and 9 females, the age ranged from 29 to 78 years old with an average of (50.30±12.28) years, the course of disease was 3 to 24 months with an average of (9.74±5.76) months. The lesion segment involved C_4,5 in 4 cases, C_5,6 in 13 cases, C_6,7 in 6 cases. The visual analogue scale (VAS), neck disability index (NDI), changes of cervical physiological curvature and interbody stability, adverse events were observed before and after operation. The follow-up time points were before operation, 1 day after operation and 1, 3 and 6 months after operation. RESULTS: All patients successfully completed the operation and manual treatment for 4 to 8 times. Among the 29 cases, 23 patients were followed up for more than 6 months. There was no spinal cord and nerve root injury during the treatment and follow-up. Operation time was from 80 to 120 min with a median of 90 min;intraoperative blood loss was from 35 to 80 ml with a median of 50 ml. NDI, VAS of neck, shoulder and arm each period after operation were significantly lower than those before PECD(P<0.05), while there were no significant improvement in cervical physiological curvature and target segment intervertebral space height(P>0.05);there was no significant change in interbody stability (P>0.05). After received the manual therapy, NDI significantly decreased (P<0.05), however, there was no significant difference in VAS of neck, shoulder and arm, physiological curvature of cervical spine and intervertebral space height of target segment compared with that before manual treatment (P>0.05);there was no significant change in interbody stability (P>0.05). CONCLUSION Manual therapy combined with PECD in the treatment of intractable cervical spondylotic radiculopathy can not only quickly improve the symptoms, but also alleviate the residual symptoms after PECD safely and effectively, and can not cause obvious signs of accelerated instability of cervical adjacent segments in the short term.
