Abstract: Objective　This study aims to explore the prevalence and risk factors of metabolic syndrome (MS) among the adults in Hainan Province, and to provide scientific basis for MS prevention and control. Methods　A multi-stage cluster random sampling method was applied to select 3 690 permanent residents aged 18 years and above in Hainan Province. The survey was conducted by trained investigators using household appointments and centralized surveys. A questionnaire survey, physical measurement, and laboratory examination were conducted after the collection of blood samples. The processed samples were then tested by a quality-controlled laboratory. Finally, we analysed the prevalence of metabolic syndrome (MS) and its relationship with population characteristics and health-related behaviors. Results　The crude prevalence of MS in the population aged 18 and above in Hainan province was 19.46% and the standardized prevalence was 13.21%, with a higher rate in urban areas (22.21%) than in rural areas (18.13%). The prevalence of MS increased with age (P<0.001), and there were significant differences in MS prevalence among different marital and occupational statuses (P<0.01). Logistic regression results indicated that the age groups of 40-<50 years (OR=2.986, 95%CI:1.355-6.580), 50-<60 years (OR=3.739, 95%CI: 1.715-8.151), 60-<70 years (OR=3.890, 95%CI: 1.769-8.556), 70 years and above (OR=3.927, 95%CI: 1.758-8.771), technical, transportation and production personnel (OR=1.579, 95%CI: 1.033-2.412), retired (OR=1.788, 95%CI: 1.415-2.259), unemployed (OR=1.503, 95%CI: 1.044-2.165), smoking cessation (OR=1.582, 95%CI: 1.162-2.154), insufficient intake of fruits and vegetables (OR=1.196, 95%CI: 1.005-1.422), and insufficient physical activity (OR=1.437, 95%CI: 1.155-1.787) were all associated with the prevalence of MS. Among the investigated subjects, 30.22% of them had one abnormal component, with hyperglycemia being the highest (54.44%); 24.25% of them had two abnormal components, with "hyperglycemia + hypertension" being the highest (33.30%); and 19.46% had three or more components, with "overweight/obesity + hyperglycemia + hypertension" being the highest (24.79%). Conclusions　The prevalence of MS in Hainan Province is on the rise, and effective lifestyle intervention measures are needed to reduce the risk of MS.

OBJECTIVETo generate a comprehensive clinical profile of intrahepatic cholestasis of pregnancy (ICP) by systematically reviewing ICP cases managed in our hospital.

METHODSThe recorded clinical data, including diagnosis, complications, management, and maternal and infant outcomes, of nine ICP cases were collected retrospectively and reviewed systematically.

RESULTSSeven of the nine total ICP patients presented with pruritus. All nine of the ICP patients showed bile acid level beyond the normal range. ICP complications included gestational hypertension (n = 3), diabetes mellitus (DM, n = 1) and impaired glucose tolerance (IGT, n = 1), and pre-eclampsia (n = 1). The infant of one patient with severe ICP showed meconium-stained liquor. All nine of the ICP patients underwent surgical delivery, of which three were delivered preterm (between the 35th and 36th week of gestation). All mothers' total bile acids declined to normal levels after delivery, and all infants survived without complication.

CONCLUSIONICP does not increase the puerpera mortality rate and does not represent a poor prognosis for infants. Bile acid levels in the ICP patients, however, may be related to the extent of premature delivery time. While the standard drug treatment of ursodeoxycholic acid is suitable for most ICP cases, those with insufficient gestational age may benefit from adjuvant corticosteroid therapy to promote fetal lung maturation prior to preterm delivery. Severe ICP cases should be managed by inducing artificial labor or performing Caesarean section.

OBJECTIVETo observe the influence of Jingu tablet (JGT) on the development and repair of osteoarthritis (OA).

METHODThe admixture of 4% papain and 0.3 mol x L(-1) cysteine was injected into the rat's knee joint to make the model of rat OA, and distilled water, Gucining Capsule and JGT was given ig simultaneously to treat for 4 weeks in succession, and then animals were killed to measure every index.

RESULTJGT could obviously improve the scope of activities of knee joint. There were significant differences between every dosage group and model group. In every dosage group, JGT could suppress the swelling of thickness of slippery membrane of joint, alleviate the inflammation symptoms of OA and obviouslical improve the pathologicol changes of slippery membrane and cartilage. JGT could also obviously reduce the content of MDA of slippery membrane and lighten the degree of cell damage.

CONCLUSIONJGT can lighten the retrograde affection of joint cartilage, obviously suppress the slippery membrane's inflammation and alleviate the scathing degree of cell. Therefore JGT has definite remedial effect to OA.

OBJECTIVETo elucidate clinical and pathological features of primary sclerosing cholangitis (PSC) in order to improve clinician's awareness of this rare disease.

METHODSWe retrospectively analyzed clinical data and follow-up information of 27 PSC patients who were admitted to Beijing Friendship Hospital from January 1990 to November 2009. The patients were classified into classic PSC and small-duct PSC according to biochemistry and imaging results. After 3 to 6 months of therapy, those patients with serum ALT < or = 1.5, TBil < or = 2 and ALP < or = 2.5 ULN were determined as good responders. The treatment results between the two groups were compared.

RESULTS9 out of 27 cases of PSC were small duct PSC and 18 cases were large bile duct or classic PSC. Male patients (7) were less than females (20) and the average age was 47.6 years. Main clinical symptoms included jaundice (85.2%), pruritis (48.1%),fatigue (68.4 %), abdominal pain (40.7%) and fever (14.8%), main physical sign included hepatomegaly (44.4%), splenomegaly (48.1 %) and ascites (14.8%). Laboratory features included elevated IgG (81.8%), positive ANA (69.6%) and pANCA (52.9%). 22% of these PSC patients had ulcerative colitis or Sjogren's syndrome. A small percentage of patients were responsive to standard therapy, of which small duct PSC had a better response than classic PSC (66.7 % vs 33.3%, P = 0.041).

CONCLUSIONSUlcerative colitis (22.2%) is not as common as reported by western countries. Small duct PSC has a better treatment response. Searching of effective treatment regimen for large bile duct PSC is warranted in future studies.

OBJECTIVETo construct an eukaryotic expression vector of open reading frame of unknown KH gene (KH-ORF), and investigate its effect on cell proliferation.

METHODSThe pCI-neo-KH-ORF expression vector was constructed by DNA recombinant technique and was introduced into COS-7 cells and K562 cells by lipofectactin-mediated DNA transfection. Expression of KH-ORF mRNA was detected by RT-PCR. The effect of KH-ORF on cell cycle of COS-7 cells and K562 cells was evaluated by flow cytometry (FCM). Effect on cell proliferation of COS-7 cells was tested by MTT assay and that on K562 cells was analyzed by growth curves and LDH activity measurement.

RESULTS(1) KH-ORF mRNA was expressed both in COS-7 cells and K562 cells. (2) The cell cycle and cell proliferation of COS-7 cells were unaffected significantly. (3) The proportion of cells in S phase was increased in pCI-neo-KH-ORF-transfected K562 cells; and growth curves and LDH activity indicated enhanced cell proliferation.

CONCLUSIONKH gene may be a leukemia gene related to proliferation of K562 cells.

OBJECTIVETo evaluate the roles of enteric nervous system neurotransmitters, nitric oxide (NO), substance P (SP) and vasoactive intestinal polypeptide (VIP), and interstitial cells of Cajal (ICC) in the colon in slow transit constipation in rats.

METHODSThirty-two healthy Wistar rats were randomly assigned to control and constipated groups. In the constipated group, the rats were daily administered with diphenoxylate (8 mg/kg) to develop slow transit constipation, while the control rats were fed with water. The number and the weight of fecal granule and the body weight of rats were recorded every 5 days for 90 days. Transit functions of intestinal movement were examined by an activated charcoal suspension pushing test one week after stopping the administration of diphenoxylate. The levels of NO and SP in the colonic mucosa were measured by nitrate reductase methods and ELISA respectively. The distribution of VIP and ICC positive cells confirmed with symbolic c-kit+ cells in the colonic wall were observed by immunohistochemical methods.

RESULTSThe daily number of fecal granule in the constipated group was significantly less than that in the control group (P<0.01). The mean weight of each fecal granule in the constipated group was significantly higher than that in the control group (P<0.01). The discharge time of the first granule of black faeces in the constipated group (430.2+/- 132.1 min) was significantly longer than that in the control group (337.2+/- 74.7 min; P<0.05). There were no significant differences in NO and SP levels and the density of VIP positive cells in the distal colonic segment between the two groups. The number of c-kit+ cells in the distal colonic wall in the constipated group was significantly reduced compared with that in the control group (P<0.05).

CONCLUSIONSThe reduction of ICC number in the distal colon may be contributed to the pathogenesis of slow transit constipation in rats.

To observe the characteristics of primary biliary cirrhosis (PBC) with a suboptimal biochemical response to ursodeoxycholic acid. A total of 38 Chinse PBC patients (5 male patients, 33 female patients, average age 55 years old) with treatment of ursodeoxycholic acid in our hospital from January 1999 to January 2009 were erolled and studied retrospectively. 17 suboptimal biochemical responders mainly presented with liver diseases related symptoms including jaundice (41.1%), fatigue, anorexia (23.5%), edema and abdominal distension (11.7%). 21 good biochemical responders mainly presented with abnormal liver function tests without symptoms. The suboptimal biochemical responders had significantly higher baseline levels of total serum bilirubin, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, immunoglobulin G and globulin as compared to the good biochemical responsers. There were no differences in gender, age and the dose of UDCA. PBC patients with liver diseases related symptoms, marked abnormal liver tests and characteristics of autoimmune hepatitis may have a suboptimal biochemical response to ursodeoxycholic acid treatment.
