Usage of Chinese Herbs in Cancer Patients in Southern China: A Survey / 中国结合医学杂志

OBJECTIVE@#To study the use of Chinese medicine (CM) in cancer patients in southern China.@*METHODS@#A total of 1,950 cancer patients finished questionnaires in four provinces in southern China. The survey included socio-demographic and clinical characteristics of participants, dosage forms, efficacy, and side effects.@*RESULTS@#The study results showed that cancer patients with higher education (>12 years) were more likely to accept the treatment of Chinese herbs. There were 54.61% (1,065 cases) of patients chose Chinese herbs for the initial treatment and 14.46% (282 cases) chose Chinese herbs as monotherapy. Most patients (54.51%, 1,063 cases) continuously used CM for more than 6 months, and a few of them (212 cases) used CM for up to 3 years. All kinds of dosage forms of CM had been used, including CM decoction, CM patent prescription and CM injection. Concerning the efficacy in the view of patients, 40.31% (786 cases) believed that it would be effective to take Chinese herbs before they starting the anti-cancer treatment, and the percentage increased to 81.08% after 1-month CM treatment. The effect of Chinese herbs was mainly demonstrated by symptom relief and improvement of quality of life, and 8.31% (162 cases) of patients experienced control of tumor growth and decreased tumor markers. Furthermore, only 14.31% (279 cases) participants reported that they experienced side effects during CM treatment.@*CONCLUSION@#This large scale investigation reflects the current situation of domestic CM usage objectively and comprehensively, which might provide new ways for cancer treatment.

Involvement of midgastric transverse band in gastric emptying delay of functional dyspepsia / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Midgastric transverse band (MTB) was first observed over 100 years ago, after that many researchers worked on the subject postulated its physiologic role and the role in gastrointestinal diseases, but its function remains unclear. With progress of imaging methods, the nature of MTB is unveiling. In this study we investigated the effect of MTB on the gastric emptying delay in functional dyspepsia (FD) and explored the mechanism.</p><p><b>METHODS</b>A total of 60 patients with FD and 65 age- and sex-matched healthy people who served as controls were studied. With (99m)Tc-DTPA labeled semi-solid fat-parched flour served as test meal, gastric emptying was examined in all subjects by using single photon emission computed tomography. Test meal was designated as general (60 g fat-parched flour) or large (80 g fat-parched flour) meal. Stomach was divided into proximal and distal parts by MTB. Half gastric emptying time, areas of different gastric parts, intragastric food distribution and MTB width were tested with in given times.</p><p><b>RESULTS</b>Patients with FD showed a delayed gastric emptying and increased intragastric residue. Global and regional gastric emptying velocity was decreased. The areas of distal stomach and MTB were significantly greater in the FD patients than in the controls. Throughout the whole test period a distal stomach-dominated food distribution was shown. Those who took a large meal had longer half gastric emptying time and greater MTB area than those who took a general meal.</p><p><b>CONCLUSIONS</b>Gastric emptying delay is related to enlarged MTB area. Some dyspeptic symptoms may be induced by abnormal distribution and increased retention of food in distal stomach. MTB, being like atria-ventricular valve that controls blood flow in heart, regulates transport, distribution, and emptying of food in the stomach.</p>

The effect of atorvastatin on the expression of CD55, CD59 in patients with hyperlipidemia / 中华心血管病杂志

<p><b>OBJECTIVE</b>To study the expressions of CD55 and CD59 in patients with hyperlipidemia and the effects of atorvastatin on it, and to identify the possible influential factors.</p><p><b>METHODS</b>We selected 67 patients with hyperlipidemia, and 24 healthy people matched in terms of age, sex and body weight as control. The expressions of CD55 and CD59 on white blood cells were detected by flow cytometry, and their relationships to blood lipids, complement activation indexes (C(5a), sC(5b-9)), inflammatory factors (high sensitivity C-reactive protein (hsCRP), TNF-alpha, IL-6 were analyzed. 24 patients with hyperlipidemia were treated with atorvastatin for 8-12 weeks and the expressions of CD55 and CD59 were measured before and after atorvastatin therapy.</p><p><b>RESULTS</b>The mean fluorescence intensity (MFI) of CD55 lymphocytes and monocytes were decreased in patients with hyperlipidemia compared with control (2.07 +/- 0.28 vs 2.29 +/- 0.44 and 3.45 +/- 1.02 vs 4.33 +/- 2.32, P < 0.01 and P < 0.05, respectively). CD55 positive lymphocyte MFI was negatively correlated with waist circumference, waist-hip ratio, hsCRP and C(5a). C(5a) was negatively correlated with the MFIs of CD55 positive lymphocytes, monocytes, granulocytes, and positively with TG and diastolic blood pressure. After atorvastatin therapy, the MFIs of CD59 positive lymphocytes, monocytes and granulocytes increased (4.34 +/- 1.16 vs 3.69 +/- 0.76, 4.52 +/- 1.36 vs 3.91 +/- 0.89, 5.67 +/- 1.72 vs 4.56 +/- 1.03, P < 0.05, < 0.05 and < 0.01 respectively), which were not correlated with changes of blood lipids.</p><p><b>CONCLUSIONS</b>The expression of CD55 is down-regulated in hyperlipidemia, which might be influenced by obesity, abdominal distribution of adipose tissue and inflammatory status of hyperlipidemia, but not by blood lipids. The expression of CD55 is related with complement activation; The expression of CD59 is up-regulated after atorvastatin treatment independently of blood lipids.</p>

Survey on the knowledge of epilepsy to patients and their family members / 中华流行病学杂志

<p><b>OBJECTIVE</b>To study the epilepsy patients and their family members on their knowledge of the disease.</p><p><b>METHODS</b>A 34-point questionnaire with 34 questions related to epilepsy knowledge was used for the survey on 170 pairs of epilepsy patients and their family members in Huashan hospital. Characters of the disease on the subjects were recorded.</p><p><b>RESULTS</b>The mean scores of the epilepsy knowledge of the patients and their family members were 16.5 +/- 8.2 and 16.1 +/- 8.5, respectively. The scores were quite low with no statistical difference between patients and their family members. The rate of correct answer in the urban subjects was obviously higher than those subjects living in the rural areas. All the subjects lacked the knowledge on the "cause of disease" when comparing with items as "diagnosis" and "treatment". Multivariate analysis showed that rural residents (P = 0.0001, OR = 52.963) and low education level (P = 0.0294, OR = 2.266) related to low epilepsy knowledge score among epilepsy patients. However, for family members, the factor related to low score was only living in the rural area (P = 0.0001, OR = 37.229).</p><p><b>CONCLUSION</b>Education on the epilepsy knowledge should be strengthened, especially in the rural areas.</p>

Effect of endomorphin on colonic electromyography activity in endomorphin cathartic colon rats / 中华老年医学杂志

Objective To determine the effect of endomorphin (EM) on colonic electromyography activity and investigate the pathogenesis of slow transit constipation (STC). Methods An experimental rat model of slow transit constipation was constructed by contract laxatives mixed with the feed. The changes of colonic electromyography and reaction to endomorphin 1 and endomorphin 2 were examined. Results Compared with the control group, the frequency and amplitude of slow wave in cathartic colon rats were decreased significantly. Endomorphin 1 and endomorphin 2 significantly decreased the amplitudes of slow wave, but did not change the frequencies of slow wave. The effect of endomorphin 1 was more pronounced than that of endomorphin 2, which could be reversed by the morphine antagonist Naloxone in concentration-dependent manner. Endomorphin could not block the stimulating effect of acetylcholine. Conclusions Endomorphin can influence the colonic electromyography activity and intestine motility of cathartic colon rats, and may be involved in the pathologic mechanism of slow transit constipation.
