In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

OBJECTIVETo investigate variations and significance of plasma fibrinogen in patients with severe acute respiratory syndrome (SARS).

METHODSTotally 148 patients with SARS were divided into the following groups: initial stage group (44 cases) and after the initial stage group (104 cases), common type group (87 cases) and severe type group (61 cases), unilobar lung involvement group (49 cases), bilobar lung involvement group (53 cases) and diffuse lung involvement group (46 cases). The values of plasma fibrinogen of the 148 SARS patients were analyzed and compared among the different groups.

RESULTSThe mean value of plasma fibrinogen (x +/- SD, 522.29 +/- 154.87 mg/dl) of the 148 cases was higher than the normal value (p less than 0.01). There were significant differences between the initial stage and after initial stage groups, between the common and severe type groups, and among the unilobar, bilobar and diffuse lung involvement groups (p less than 0.05).

CONCLUSIONtheses results suggested that elevation of peripheral blood fibrinogen in SARS patients may play an important role in development and progress of the disease and its treatment.

OBJECTIVETo investigate the clinical features of severe acute respiratory syndrome (SARS).

METHODSForty-one medical care workers (aged 23 - 55 years, with a average of 32 years; men/women = 8/32) who were admitted to our hospital and diagnosed with SARS during March and April, 2003 were retrospectively analyzed.

RESULTSThirteen of all the patients were physicians and the rest were nurses. The disease was mainly transmitted through air droplet in a short distance, and overwork induced tiredness was involved in disease stimulation. Seventy-three percent of the patients presented fever as their first symptom. Ten patients complained inertia and myalgia. One patient showed no clinical symptoms, and bilateral infiltrates was found in his chest X-ray. Among the 41 cases, 6 (15%) were diagnosed as severe type. At the first week, the counts of white blood cells (WBCs), lymphocyte and platelets were (4.4 +/- 1.5) x 10(9)/L, 0.22 +/- 0.12 and (143 +/- 37) x 10(9)/L, which were significantly lower when compared with those at the 2nd to 4th week. Abnormal liver function was found in 27 cases (mostly with elevated serum ALT), with 70% occurred at the 3rd or 4th week. In terms of CT, 30 patients (73%) showed pathological changes in lungs, and bilateral lung involvement was found in 35.59%. Of 36 cases treated with steroids, 86% received middle or low dosage (80 - 240 mg/d). Artificial ventilation was used for twenty-seven patients, and air pipe mechanical ventilation was used for 1 case. Mortality in this study was 5%.

CONCLUSIONSInertia and myalgia may be the earlier symptoms of health care workers with SARS include, which are parallel to CT manifestations. There is no objective index for the assessment of the severity of the disease at early stage. The medicine associated toxicities may be the main reason of liver lesions. damages. Middle or low dosage of steroid was reasonable to be used as early as possible.

Recurrent spontaneous abortion (RSA) has various complicated causes, and more and more researches are focused on its etiology. Genetic factors are the most common risk factors of RSA; immune factors, infection factors, male factors and female factors play an important role; environmental pollution and some other unknown factors may also be conspirators. This article presents an overview on the possible risk factors of RSA.

Progesterone, as a female hormone, plays an important role in the physiological function and pregnancy maintenance in women. Recent studies show that progesterone and its receptor are also involved in male reproduction, and its receptor mRNA exists in male sexual glands. It is believed that progesterone, binding to its receptor, can regulate spermatogenesis and improve the fertilization of sperm, while the sperm from those with oligospermia, asthenozoospermia, teratospermia or unexplained infertility exhibit a low fertility due to the deficient expression of the progesterone receptor and insensitive reaction to progesterone. This review focuses on the progress in the studies of progesterone and its receptor in male reproduction.

OBJECTIVETo study the impact of the chloride channel dysfunction of the cystic fibrosis transmembrane conductance regulator (CFTR) on the cytoskeleton of Sertoli cells in the mouse.

METHODSTM4 Sertoli cells were cultured and treated with CFTR(inh)-172 at the concentrations of 1, 5, 10 and 20 μmol/L for 48 hours. Then the cytotoxicity of CFT(inh)-172 was assessed by CCK-8 assay, the expressions of F-actin and Ac-tub in the TM4 Sertoli cells detected by immunofluorescence assay, and those of N-cadherin, vimentin and vinculin determined by qPCR.

RESULTSCFTR(inh)-172 produced cytotoxicity to the TM4 Sertoli cells at the concentration of 20 μmol/L. The expressions of F-actin and Ac-tub were decreased gradually in the TM4 Sertoli cells with the prolonging of treatment time and increasing concentration of CFTR(inh)-172 (P < 0.05). The results of qPCR showed that different concentrations of CFTR(inh)-172 worked no significant influence on the mRNA expressions of N-cadherin, vimentin and vinculin in the Sertoli cells.

CONCLUSIONThe CFTR chloride channel plays an important role in maintaining the normal cytoskeleton of Sertoli cells. The reduced function and expression of the CFTR chloride channel may affect the function of Sertoli cells and consequently spermatogenesis of the testis.

OBJECTIVETo investigate the expression of Wnt and integrin pathways in colorectal laterally spreading tumors (LSTs) and their correlation with the different endoscopic subtypes of LSTs to better understand the special growth mechanism of LSTs.

METHODSFifty-two patients with colorectal LSTs were randomly selected from the cases diagnosed between January 1, 2010 and June 10, 2015 in our hospital, including 37 of nodular mixed type (LST-G-M), 60 of homogeneous type (LST-G-H), 5 of flat elevated type (LST-NG-FE), and 4 of pseudodepressed type (LST-NG-PD). The expression of β-catenin, phospho- GSK-3β, paxillin and ILK in 52 colorectal LSTs and 15 protruded adenomas (PAs) were investigated by immunohistochemical staining. The correlation of β-catenin, phospho-GSK-3β, paxillin and ILK expressions among the endoscopic subtypes of LSTs were analyzed.

RESULTSβ-catenin expression was significantly higher in LSTs than in Pas (P<0.05). β-catenin, phospho-GSK-3β, paxillin and ILK expressions were significantly higher in LST-NG-PD than in Pas (P<0.05). The expressions of β-catenin, phospho-GSK-3β and ILK expression were significantly correlated in LSTs (P<0.05) but not in PAs (P>0.05).

CONCLUSIONThe macroscopic feature of LST-NG-PD may result from a special mechanism of development distinct from other endoscopic subtypes; ILK may play a role in regulating Wnt signaling in LSTs.

BACKGROUNDThe aim of this research was to explore quality of life (QOL) and acceptance of disability and social support of colostomy patients as well as the relationship between these factors.

METHODSA descriptive, correlational study was conducted using four scales: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and European Organization for Research and Treatment of Cancer Colorectal Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-CR38) scales, the Acceptance of Disability Scale (ADS), and the Social Relational Quality Scale (SRQS). A convenience sample of 111 colostomy patients from four hospitals in Guangzhou who underwent colostomy operation at least one month prior to the study and who visited the stoma clinic or association from August 2011 to February 2012 was evaluated for inclusion in the study. All statistical analyses were performed using SPSS 17.0 software (SPSS Inc., Chicago, IL, USA).

RESULTSThe patients' general health status was better than the reference level recommended by European Organization for Research and Treatment of Cancer, and the overall ADS score was average. The SRQS score was similar to that found in a Hong Kong study. The general health status and dimensions of QOL were significantly correlated with ADS and all of its dimensions (P < 0.05). The general health status and dimensions of QOL were also significantly correlated with SRQS and all of its dimensions (P < 0.05).

CONCLUSIONSQOL, acceptance of disability, and social relational quality of colostomy patients were closely related. Our results emphasize that patients should work to form rational values and close bonds with families and friends to achieve a better QOL.
