Use of Iodized Oil and Gelatin Sponge Embolization in Splenic Artery Coiling Reduces Bleeding from Laparoscopic Splenectomy for Cirrhotic Portal Hypertension Patients with Complicating Hypersplenic Splenomegaly: A Comparative Study.

OBJECTIVE: Laparoscopic splenectomy (LS) is relatively contraindicated in cirrhotic portal hypertension (CPH) patients with complicating hypersplenic splenomegaly (HS). This study aimed to evaluate the effectiveness and safety of incorporation of iodized oil and gelatin sponge embolization to conventional splenic artery embolization (cSAE) with coiling in CPH/HS patients undergoing LS. PATIENTS AND METHODS: Between April 2012 and March 2014, eligible CPH/HS patients (n = 56) were assigned to preoperative modified SAE (mSAE) with LS (mSAE+LS group, n = 16), cSAE with LS (cSAE+LS group, n = 20) or LS alone (LS group, n = 20). Main outcome measures included frequency of conversion to laparotomy, operative time, intraoperative bleeding, and transfusion. RESULTS: The three groups had similar baseline characteristics (all P > .05). mSAE and cSAE similarly decreased LS conversion frequency (mSAE+LS versus cSAE+LS versus LS, 0.0% versus 10.0% versus 30.0%, P = .030) and operative time (155 ± 23 minutes versus 170 ± 26 minutes versus 221 ± 42 minutes, P < .001) compared with LS alone. mSAE significantly reduced bleeding (178 ± 22 mL versus 250 ± 27 mL versus 328 ± 67 mL, P < .001) compared with cSAE and LS alone. The three groups had similar postoperative recovery times and surgical morbidities (all P > .05). CONCLUSIONS: In CPH/HS patients, preoperative SAE reduced LS conversion frequency and reduced operative time compared with LS alone, while mSAE further decreased volume of blood loss.

Research progress in Litsea glutinosa / 中草药

Litsea glutinosa, belonging to family Lauraceae, is widely distributed in subtropical and tropical regions. L. glutinosa was used to cure many diseases as folk medicine in China. It has proved that the plant showed anti-diabetic, anti-inflammatory, and anti-bacterial activities. So far, more than 50 compounds including flavonoids, alkaloids, and lignans have been isolated from this plant. Alkaloids were deemed as its characteristic constituents. This review summarized the biological activities and chemical constituents of L. glutinosa for the first time. Based on these collected information, we pointed out that little information was found related to the potential mechanism of the biological effects. Moreover, there were few reports regarding the biological evaluation of the isolated compounds. As the development of new technique in isolation and biochemistry, close attention should be paid to biological evaluation and potential mechanism.

Low-dose green tea intake reduces incidence of atrial fibrillation in a Chinese population.

The aim of the present study was to assessthe association between green tea intake and incidence of atrial fibrillation (AF) in a Chinese population. A total of 801 (mean age: 62 years; 56% male) subjects were enrolled: 401 AF patients and 400 controls. All subjects completed a questionnaire and the associations between their green tea drinking habits and incidence of AF were assessed using the odds ratio (OR) and binary logistic regression. After multivariate adjustment, green tea intake presented as a protective factor against the incidence of AF (OR: 0.349, 95% CI: 0.253-0.483, P < 0.001). The green tea protection showed downward trend with increasing green tea intake (P for the trend= 0.001). Low frequency, low concentration, short-term tea consumption was classified as low-dose green tea intake. Green tea intake decreased the incidence of both paroxysmal AF (OR: 0.307, 95% CI: 0.216-0.436, P < 0.001) and persistent AF (OR: 0.355, 95% CI: 0.261-0.482, P < 0.001) and may be associated with a decreased incidence of AF. This study suggests that low-dose green tea intake strongly protects against AF.

[Effect of Danzhi Jiangtang Capsule on Myocardial Fibrosis in Diabetic Rats].

OBJECTIVE: To investigate the effect of Danzhi Jiangtang Capsule on myocardial fibrosis in diabetic rats with fluctuated blood glucose and the possible mechanisms implicated. METHODS: Following induction of diabetes with intraperitoneal injection of streptozotocin (STZ), rats were administered with insulin or glucose at different time during a day to induce blood glucose fluctuation. After treatment with Danzhi Jiangtang Capsule for six weeks, rats were sacrificed and the hearts were collected for the determination of cardiac mass index. Cardiac levels of angiotensin II (Ang II), type I and type III collagens and transforming growth factor-ß1 (TGF-ß1) were assayed by ELISA. Levels of Smad3 phosphorylation and protein expression of matrix metalloproteinase-2 ( MMP-2) and tissue inhibitor of matrix metalloproteinase-2 (TIMP-2) were determined by Western blot analysis. Total antioxidant capacity and malondialdehyde (MDA) content in cardiac tissues were measured colorimetrically. RESULTS: Treatment with Danzhi Jiangtang Capsule for six weeks significantly reduced cardiac mass index and cardiac levels of type I and type III collagens (P < 0.05 or P < 0.01). Levels of Ang II, TGF-ß1 and Smad3 phosphorylation in cardiac tissues were also decreased markedly (P < 0.05 or P < 0.01). Supplementation with Danzhi Jiangtang Capsule resulted in an evident up-regulation of MMP-2 protein and down-regulation of TIMP-2 protein expression in cardiac tissues (P < 0.05 or P < 0.01). In addition, Danzhi Jiangtang Capsule significantly enhanced total antioxidant capacity in diabetic rats, while cardiac content of MDA was decreased markedly( P < 0.05 or P < 0.01). CONCLUSION: Danzhi Jiangtang Capsule significantly ameliorated myocardial fibrosis in diabetic rats with fluctuated blood glucose, which might be derived from enhancement of antioxidant capacity, suppression of RAS and TGF-ß1/Smad3 signaling pathway and regulation of MMP-2/TIMP-2 protein expression.

MicroRNA-34a targets Bcl-2 and sensitizes human hepatocellular carcinoma cells to sorafenib treatment.

MiR-34a, a direct target of p53, has been shown to target several molecules associated with the cell cycle and cell survival pathways, and its dysregulation is implicated in cancer drug resistance or sensitivity in several human cancers. However, the correlation between miR-34a expression and chemoresistance has not been explored in HCC. In this study, we confirmed that miR-34a was significantly down-regulated in HCC tissues and HCC cell lines by qRT-PCR. HCC tissues with lower miR-34a expression displayed higher expression of Bcl-2 protein than those with high expression of miR-34a; therefore, an inverse correlation is evident between the miR-34a level and Bcl-2 expression. Moreover, patients with lower miR-34a expression had significantly poorer overall survival. Bioinformatics and luciferase reporter assays revealed that miR-34a binds the 3'-UTR of the Bcl-2 mRNA and represses its translation. Western blotting analysis and qRT-PCR confirmed that Bcl-2 is inhibited by miR-34a overexpression. Functional analyses indicated that the restoration of miR-34a reduced cell viability, promoted cell apoptosis and potentiated sorafenib-induced apoptosis and toxicity in HCC cell lines by inhibiting Bcl-2 expression. This study is the first to demonstrate that miR-34a induces sensitivity to the anti-tumor effect of sorafenib in human HCC cells, suggesting a potential role of miR-34a in the treatment of HCC.

[Affection of acupotomy lysis on leu-enkephalin (L-ENK) content in different parts of centrum of rats with knee osteoarthritis].

OBJECTIVE: To study the analgesia mechanism of needle-knife lysis in spinal cord and other parts of central nervous system by comparing the changes of Leu-Enkephalin (L-ENK) content in different parts of centrium of rats undergone needle-knife lysis and electro-acupuncture respectively. METHODS: Sixty healthy SD rats were randomly devided into normal control group, model group, needle-knife lysis (NKL) group and electro-acupuncture (EA) group. 4% papain solution mixed with 0.3 mol/L cysteine solutin in the ratio of 1:1, paused for 0.5 h,injected the mixture, 20 microl each time,into the left knee joint cavities of rats in model, NKL, EA groups at the 1st, 4th, 7th day. After 4 weeks in NKL group and EA group were treated with needle-knife lysis and electro-acupuncture, respectively. Three weeks after treatment, samples of spinal cord of the swollen part of rat waists and rat brains were taken from and the content of L-ENK of medulla oblongata, midbrain, pituitary gland, and hippocampus were measured. RESULTS: L-ENK content of model group increased higher than that of normal control group in spinal cord, hippocampus and midbrain (P < 0.01); there were no significant difference between normal control group and modle group on L-ENK in medulla oblongata and thalamus (P > 0.05). After intervening of NKL or EA, L-ENK content of NKL group increased higher in hippocampus than that of model group and EC group (P < 0.05); but L-ENK content of NKL group in midbrain was lower than that of model group (P < 0.05). CONCLUSION: Needle-knife lysis has characteristic of regulation for the L-ENK content in different parts of central nervous system of rats with knee osteoarthritis, and analgesic effect of needle-knife was possibly related with regulation of center L-ENK.

A brief on pain and its patterns in Chinese medicine.

Pain is the most common symptom in clinics. Therefore, the quality, time course and location of pain are important for the diagnosis and treatment. However, pain is very difficult to define, and it is one of the conditions poorly understood by the medical sciences. In Western medicine pain is often described in terms of a penetrating or tissue-destructive process and/or emotional reactions, but in Chinese medicine the pathogenesis and description of pain are different. It is described based on the theories and pathogenesis of Chinese medicine, and the patients' feeling according to their languages and cultures. Thus, when taking the history and conducting physical examination in patients in China and treating them according to Chinese medicine, we have to know how these patients express and describe their pain when they go to clinics. This article will explain some terms and words in the Chinese language and their corresponding terms in the English language.
