Objective To investigate the effects ofTiaogan Lipi Huaji Prescription combined with high intensity focused ultrasound (HIFU) for the treatment of locally advanced pancreatic cancer.Methods Randomized, parallel controlled study was designed to select 60 patients with locally advanced pancreatic cancer, which were divided into treatment group and control group by random number table method, 30 cases in each group. The treatment group was givenTiaogan Lipi Huaji Prescription, one dose per day, twice a day, orally, 28 d as a treatment course, 6 courses in total; at the same time, HIFU was given to the treatment group, 30–60 min each time, once every other day, 2–3 times each week, and the tumor was completely covered for 2 times. The control group was given gemcitabine 1000 mg/m2, intravenous infusion, 1st, 8th d, 21–28 d for a cycle, a total of 6 cycles. The clinical benefit response, QOL-C30 score, survival status, progression-free survival (PFS), CA199 and CEA levels were observed.Results Clinical benefit rates of treatment group and control group were: the treatment group 1, 3, 6 months clinical benefit rate was 64.29%, 63.16%, and 50.00%, respectively; control group clinical benefit rate was 48.15%, 40.00%, and 44.44%, respectively, with statistical significance (P<0.05). The difference of QOL-C30 score between the two groups at the same time wasstatistically significant (P<0.05). During the treatment 1 to 6 months, CA199 in the two groups showed a downward trend, without statistical significance (P>0.05). CEA levels in the treatment group were lower than those in the control group at the same time with statistical significance (P<0.05), except for 2 and 6 months. The survival rates of treatment of 3, 6, and 12 months in the treatment group were 82.14%, 46.42% and 32.14%, respectively, and were 96.67%, 59.32% and 37.04%, respectively in the control group, without statistical significance (P>0.05). The survival time of the treatment group was (253.90±18.06)d in the control group and (246.77±17.31)d in the control group, without statistical significance (P>0.05). PFS was (136.73±16.22)d in the treatment group and (145.77±19.74)d in the control group, without statistical significance (P>0.05).ConclusionTiaogan Lipi Huaji Prescription combined with HIFU for the treatment of locally advanced pancreatic cancer has certain clinical efficacy, which can improve patients' life quality.

OBJECTIVETo evaluate the efficacy and safety of tiaogan Lipi Recipe (TLR) in treating non-alcoholic fatty liver disease (NAFLD) patients of Gan stagnation Pi deficiency syndrome (GSP-DS).

METHODSA randomized, double blind, placebo-controlled clinical trial was performed. Totally 99 NAFLD patients of GSPDS were randomly allocated into two groups, 66 patients in the treatment group (treated with-TLR, one dose per day) and 33 patients in the control group (treated with placebos, one dose per day). The therapeutic course for all was 12 weeks. All patients received lifestyle interventions including moderate aerobic exercise, moderate caloric restriction, and dietary changes. Clinical symptoms, CT indices, liver functions and blood lipids were observed before and after treatment.

RESULTSAfter 12 weeks of treatment, the total score of clinical symptoms decreased in the two groups (P <0. 01), and it was lower in the treatment group than in the control group (P <0. 05). Liver/spleen CT ratio increased in the treatment group (P <0. 01), and it was higher in the treatment group than in the control group (P <0. 01). After treatment levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT) all decreased in the treatment group (P <0. 05, P <0. 01), while levels of ALT decreased in the control group (P <0. 05). Besides, all the 3 levels mentioned above were lower in the treatment group than in the control group (P <0. 05). Levels of total cholesterol (CHO) and triglyceride (TG) decreased in the two groups (P <0. 05), and they were lower in the treatment group (P <0. 05). Total effective rates of TCM syndrome, abdominal CT, liver functions, and blood lipids were 79. 69% (51/64 cases), 54. 69% (35/64 cases), 67. 65% (23/34 cases), and 67. 39% (31/46 cases) in the treatment group, while they were 56. 25% (18/32 cases), 25. 00% (8/32 cases), 33. 33% (6/18 cases), and 55. 56% (10/18 cases) in the control group. All were superior in the treatment group (P <0.05, P <0.01, respectively).

CONCLUSIONTLR combined with lifestyle intervention could safely and effectively improve clinical symptoms of NAFLD patients of GSPDS, elevate liver/spleen CT ratios, and play a role in liver protection, anti-inflammation, and lowering blood lipids.

OBJECTIVETo explore the mechanisms of Qianjing Decoction in the treatment of oligoasthenospermia (OAS).

METHODSWe randomly divided 100 SPF male rats into five groups of equal number: normal, model, Huangjingzanyu, levocarnitine, and Qiangjing. OAS models were established in the animals followed by intragastrical administration of normal saline, ornidazole, Huangjingzanyu Capsules (200 mg per kg body weight per day), levocarnitine (100 mg per kg body weight per day), and Qianjing Decoction (10 g per kg body weight per day), respectively, qd, for 4 successive weeks. Then, we detected the concentration and motility of the epididymal sperm, obtained the contents of superoxide dismutase (SOD), malonaldehyde (MDA), glutathione peroxidase (GSH-Px), lactate dehydrogenase (LDH), α-glucosidase, and fructose in the epididymis, and determined the mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and succinate dehydrogenase (SDH) in the epididymal tissue of the rats by real-time PCR.

RESULTSThe concentration and motility of the epididymal sperm in the model, Huangjingzanyu, levocarnitine, and Qianging groups were (35.34 ± 4.22) x 10(6)/ml and (40.04 ± 7.05)%, (48.12 ± 5.56) x 10(6)/ml and (62.46 ± 7.12)%, (47.14 ± 4.87) x 10(6)/ml and (63.23 ± 6.34)%, and (50.25 ± 5.08) x 10(6)/ml and (66.34 ± 7.58)%, respectively, all significantly lower than in the normal group ([53.05 ± 4.55] x 10(6)/ml and [70.20 ± 8.54]%) (P < 0.05), but remarkably higher in the Huangjingzanyu, levocarnitine, and Qiangjing groups than in the model rats (P < 0.05). Compared with the thinned epididymal lumen walls, decreased sperm count, and disorderly and loose arrangement of the lumens in the OAS models, the rats in the Huangjingzanyu, levocarnitine, and Qiangjing groups showed evidently thicker epididymal lumen walls, with the lumens full of sperm cells and arranged regularly and compactly, similar to those of the normal rats. The levels of SOD and GSH-Px were significantly lower but that of MDA markedly higher in the model rats ([84.12 ± 23.25], [10.56 ± 3.02], and [14.04 ± 2.06] nmol/mg) than in the normal group ([110.04 ± 19.56], [17.25 ± 3.56], and [8.87 ± 1.35] nmol/mg) (P < 0.05), while the former two indexes remarkably higher and the latter one significantly lower in the animals treated with Qiangjing Decoction ([120.56 ± 23.68], [16.34 ± 3.12], and [8.45 ± 1.56] nmol/mg), Huangjingzanyu Capsules ([115.34 ± 21.35], [15.23 ± 3.67], and [8.33 ± 1.54] nmol/mg), and levocarnitine ([116.67 ± 22.67], [15.35 ± 3.45], and [8.05 ± 1.78] nmol/mg) than in the models (P < 0.05). The levels of fructose, LDH and α-glucosidase were decreased markedly in the OAS models ([100.22 ± 12.12] mg/[ ml x g], [322 ± 46.13] U/[ ml x g], and [10.48 ± 2.33] U/[ml x g]) as compared with the normal rats ([128.12 ± 13.45] mg/[ml x g], [428 ± 35.12] U/[ml x g], and [15.34 ± 3.12] U/[ ml x g]) (P < 0.05), remarkably higher in the rats treated with Qiangjing ([130.23 ± 13.67] mg/[ml x g] [455 ± 51.50] U/[ml x g], and [18.56 ± 4.67] U/[ml x g]), Huangjingzanyu ([124.16 ± 14.02] mg/[ml x g], [ 419 ± 43.14] U/[ml x g], and [17.64 ± 4.08] U/[ml x g]), and levocarnitine ([123.34 ± 14.02] mg/[ml x g], [430 ± 31.80] U/ [ml x g], and [16.85 ± 5.55] U/[ml x g]) than in the models (P < 0.05). The Nrf2 mRNA expression was significantly reduced in the models as compared with the normal rats (P < 0.05) but remarkably increased in the Huangingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05). The SDH mRNA expression was significantly lower in the model than in the normal rats (P < 0.05) but markedly elevated in the Huangjingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05), remarkably higher in the Qiangjing than in the Huangjingzanyu group (P < 0.05).

CONCLUSIONOrnidazole induces OAS in rats, which is closely associated with excessive oxidation and energy metabolism dysfunction. Qiangjing Decoction can improve and even reverse ornidazole-induced OAS in rats as well as improve the ultrastructure of their testicular and epididymal tissues. Antioxidation and improvement of energy metabolism are probably the action mechanisms of Qiangjing Decoction in the treatment of OAS.

OBJECTIVETo investigate mRNA expression of integrin beta3 in gastric carcinoma, its correlation with microvascular density (MVD), growth-pattern, invasion, metastasis and prognosis.

METHODSIn situ hybridization and immunohistochemistry techniques were used to study the expression of integrin beta3 mRNA and CD34 protein in 105 gastric carcinoma specimens.

RESULTSIn situ hybridization revealed a 30% (6/20) positive rate of integrin beta3 mRNA in non-tumor gastric mucosa, which was significantly lower than that of the gastric cancer group (61.0%, 64/105, chi(2) = 8.85, P = 0.037); In infiltrating type cases (70.2%, 40/57), stage III - IV (72.1%, 44/61), lymphatic metastasis (68.6%, 48/70) and distant metastasis (85.7%, 36/42), the positive expression rates were significantly higher than those of the expanding type (chi(2) = 14.97, P = 0.002), stage I - II (chi(2) = 15.21, P = 0.015), non-lymphatic metastasis (chi(2) = 17.89, P = 0.025) and non-distant metastasis (chi(2) = 20.22, P = 0.005; chi(2) = 21.35, P = 0.035); its mean MVD was also significantly higher than that of the expanding type (t = 10.105, P = 0.001), stage I approximately II (t = 5.961, P = 0.001), non-lymphatic metastasis (t = 3.819, P = 0.01)and non-distant metastasis (t = 10.578, P = 0.001; t = 7.882, P = 0.001), respectively; The mean MVD (41.02 +/- 8.55)/0.72 mm(2) of the integrin beta3 mRNA positive expression group was significantly higher than (25.26 +/- 11.25)/0.72 mm(2) of the negative expression group. There was a positive relation between MVD and integrin beta3 mRNA expression in the tumor (r(s) = 0.316, P = 0.001). The mean survival time in cases with positive integrin beta3 mRNA expression or MVD value >or= 39.5 was significantly shorter than that in cases with negative expression or MVD value < 39.5.

CONCLUSIONSIntegrin beta3 expression correlates with enhanced tumor angiogenesis and may play a role in the invasion and nodal metastasis of gastric carcinoma, therefore it may serve as a prognostic marker of gastric cancer.

The axon guidance molecule Slit is a secreted glucoprotein which is conserved during evolution. Slit has been implicated in regulating a variety of life activities, such as axon guidance, neuronal migration, neuronal morphological differentiation, tumor metastasis, angiogenesis and heart morphogenesis. Slit function mainly depends on the binding of its LRR-2 domain to the Ig1 domain of Roundabout (Robo) receptor, meanwhile Slit function is also mediated by a range of signaling molecules, including the heparan sulfate proteoglycans (HSPGs), GTPase-activating proteins (GAPs), tyrosine kinase Abelson, calcium ions, MicroRNA-218 and other axon guidance molecules. Several transcription factors, including Single-minded, Irx and Midline, were shown to regulate slit expression. In addition, multiple Slit isoforms exist as a consequence of alternative spliced transcripts. The research on guidance mechanism of Slit will facilitate the understanding of molecular mechanism underlying neural networks formation in the process of neural development and regeneration. Meanwhile, the studying of Slit guidance mechanism could promote the prevention and treatment of human neurological diseases and cancer metastasis.

Objective To analyze longitudinal layer‐specific strain in endocardial ,midcardial and epicardial layers of left ventricle (LV) by two‐dimensional speckle tracking imaging(2D‐STI) in patients with coronary heart disease (CHD) and to evaluate the regional or global systolic function of LV . Methods Seventy‐eight patients with suspected CHD were divided into CHD group (46 subjects) and control group (32 subjects) according to the results of selective coronary arteriography . According to the stenosis degree or number of coronary arteries ,the CHD group was divided into mild stenosis group ( corresponding blood‐supply vessel stenosis 50% -75% ) ,severe stenosis group ( corresponding blood‐supply vessel stenosis ≥75% ) or single‐vessel stenosis group ,multi‐vessel stenosis group . Two‐dimensional images with high frame rate were recorded in apical four‐chamber ,long‐axis ,two‐chamber of LV in all subjects . The strain parameters by EchoPAC analysis software included territorial longitudinal strain ( TLS ) of endocardial , midcardial and epicardial layers ( TLSendo ,TLSmid ,TLSepi) and global longitudinal strain ( GLS) of endocardial ,midcardial and epicardial layers ( GLSendo ,GLSmid ,GLSepi) . Results Regardless of with or without corresponding blood‐supply coronary artery stenosis and range of coronary artery stenosis , TLSendo ,TLSmid ,TLSepi and GLSendo ,GLSmid ,GLSepi all showed a gradient decrease( P < 0 .05) . Compared with the control group ,TLSendo ,TLSepi of mild stenosis group and severe stenosis group decreased significantly( P <0 .05) ,while there was no significant difference about TLSmid between the two groups( P > 0 .05) . Compared with the mild stenosis group ,TLSendo ,TLSepi of severe stenosis group decreased significantly( P < 0 .05) ,while there was no significant difference about TLSmid( P > 0 .05) . Moreover ,compared with the control group ,GLSendo ,GLSmid ,GLSepi of single‐vessel stenosis group and multi‐vessel stenosis group decreased significantly( P < 0 .05) . Compared with the single‐vessel stenosis group ,GLSendo ,GLSmid ,GLSepi of multi‐vessel stenosis group decreased significantly( P < 0 .05) . For predicting corresponding blood‐supply vessel stenosis ≥75% ,the sensitivity and specificity were 55 .6% , 72 .6% and 57 .8% ,76 .4% ,when the cut‐off of TLSendo and TLSepi were 20 .5% and 15 .5% respectively . For predicting multi‐vessel stenosis ,the sensitivity and specificity were 54 .5% ,71 .4% ;50 .0% ,87 .5% and 63 .6% ,87 .5% ;when the cut‐off of GLSendo , GLSmid , GLSepi were 21 .5% , 17 .5% and 16 .5%respectively . Conclusions Systolic dysfunction of LV happened through all layers in CHD patients . The longitudinal strain of layer‐specific by 2D‐STI can accurately evaluate the regional and global systolic function of LV in patients with CHD ,which can also be used to predict the degree or range of coronary artery stenosis .
