OBJECTIVETo compare the differences in the therapeutic effect on irritable bowel syndrome (IBS) between acupuncture at Tianshu (ST 25) and Dachangshu (BL 25) and western medication with Trimebutine Maleate.
METHODSForty cases were divided randomly into an acupuncture group and a western medication group, 20 cases in each one. In acupuncture group, acupuncture was applied to Tianshu (ST 25) and Dachangshu (BL 25). Ziwu Daojiu needling technique was adopted, once daily. In western medication group, Trimebutine Maleate capsule was administered, 2 capsules in each time, 3 times per day. The assessment on the therapeutic effect was performed in 4 weeks of treatment in two groups.
RESULTSAs compared with those before treatment, the time of abdominal pain, the frequency of abdominal pain, the morbidity of abnormal stool appearance, the morbidity of defecation abnormality, the morbidity of mucus stool and the score of bloating or abdominal pain on bowel movement were all reduced after treatment in two groups (all P < 0.01). The results in acupuncture group were much more significant than those in western medication group (the total score: 16.70 +/- 2.40 vs 15.70 +/- 3.01, P < 0.01). The total effective rate in acupuncture group was 95.0% (19/20), which was superior to that of 70.0% (14/20) in western medication group (P < 0.05).
CONCLUSIONAcupuncture at Tianshu (ST 25) and Dachangshu (BL 25) may remarkably relieve the clinical symptoms of IBS and its efficacy is superior to that of oral medication with Trimebutine Maleate.

OBJECTIVETo explore the role of expression of connective tissue growth factor (CTGF) in pulmonary vascular remodeling of pulmonary hypertensive rats, and investigate the regulation of CTGF expression by simvastatin in this animal model.
METHODSEighty male Sprague-Dawley rats (350 to 400 g) were randomized to 7 groups. The rats in group PM(1 - 21) (n = 10) and PM(1 - 35) (n = 12) were treated with pneumonectomy + monocrotaline (MCT), and sacrificed at the 21st or 35th experimental day;those in groups PMS(1 - 35) (n = 12), PMS(21 - 35) (n = 12), PMV(1 - 35) (n = 12) and PMV(21 - 35) (n = 12) were given daily lavage of simvastatin (or vehicle) as intervention measure which began from the 1st and 21st experimental days, respectively; additional 10 rats were used as control without any intervention. The animals were sacrificed at the end of experiment (35 th day) as hemodynamic measurements and study on the morphological parameters relevant to pulmonary vascular remodeling were performed on each group of rats. The expression of ET-1 mRNA, CTGF mRNA and protein, and synthesis of collagen in these pneumonectomized, MCT-treated rats were compared between control and rats treated with simvastatin.
RESULTSRats in PM(1 - 35) Group developed severe PAH (mPAP = 39.75 +/- 3.62 mm Hg) (1 mm Hg = 0.133 kPa), right ventricular hypertrophy [RV/(LV + S) ratio = 0.627 +/- 0.040], and arterial medial hypertrophy (WT% = 61.73 +/- 5.39), these parameters of the control animals were 17.10 +/- 1.20 mm Hg, 0.262 +/- 0.018 and 14.71 +/- 1.16, respectively. CTGF mRNA and protein were mainly located in pulmonary arterial smooth muscle cells and interstitial macrophage shown by in situ hybridization and immunohistochemistry, respectively. The expression of ET-1 mRNA and CTGF mRNA detected by fluorescent quantitative RT-PCR in Group PM(1 - 35) were significantly increased in comparison with controls, and so did the CTGF protein expression determined by Western blotting in these diseased rats. The content of hydroxyproline (1.30 +/- 0.19 microg/mg wet lung) was remarkably higher than that of control animals (0.56 +/- 0.10 microg/mg wet lung). The up-regulation of ET-1 and CTGF gene expression, and elevated synthesis of hydroxyproline were reversed in rats intervened with simvastatin. The pulmonary hypertension, right ventricular hypertrophy and medial hypertrophy were attenuated in all simvastatin-treated rats no matter the intervention was initiated from the beginning or midway of the study.
CONCLUSIONThe up-regulation of CTGF gene expression may play an important role in the development of pulmonary vascular remodeling in PAH. Simvastatin can prevent and, to some extent, reverse the vascular remodeling via down-regulation of CTGF gene expression.

OBJECTIVEBased on establishment of four rat models of experimental pulmonary hypertension (PH), the authors examined the inhibition of matrix metalloproteinases (MMPs) by doxycycline and its effect on the development of PH and associated pulmonary vascular remodeling.
METHODHealthy male Sprague-Dawley rats (weight 350 g to 400 g) were randomly divided into nine groups: Normal control group (N), four model groups (H, M, P, PM) and their corresponding drug intervention groups (HD, MD, PD, PMD) in which doxycycline was given by gavage at a 20 mg/kg daily dosage. On day 28 (day 35 for PM and PMD models), the animals were catheterized to record mean pulmonary arterial pressure (mPAP) and then sacrificed. Fulton Index [RV/(LV + S)] was measured immediately. Morphometric parameters, including percent vascular wall thickness and muscularization of non-muscularized peripheral pulmonary arterioles were determined microscopically. The activity of MMPs was measured by gelatin zymography in the lung tissue.
RESULTS(1) Rats in all model groups (H, M, P, PM) developed significant pulmonary arterial hypertension and right ventricular hypertrophy in comparison with their corresponding drug intervention groups (HD, MD, PD, PMD) and normal control group (N) (P < 0.01). For example, mPAP (mm Hg)(1 mm Hg = 0.133 kPa):N: 18.10 +/- 1.45, H: 27.20 +/- 1.55, HD: 23.90 +/- 2.13; Fulton Inedx(%):N: 23.41 +/- 1.84, H: 34.44 +/- 2.70, HD: 27.55 +/- 2.45. (2) The percent vascular wall thickness (WT%) and percentage of muscularization of non-muscular pulmonary arterioles were significantly increased in all model groups compared with drug intervention groups and normal group (P < 0.01). For example, WT%:N: 10.90 +/- 3.11, H:41.41 +/- 5.21, HD: 17.73 +/- 3.12; Muscularization(%):N: 13.83 +/- 3.72, H: 44.93 +/- 2.43, HD: 29.89 +/- 4.45. (3) The activity of MMPs was inhibited by doxycycline effectively as assessed by gelatin zymography (P < 0.01). For example, the activity of MMP2 (A x 10(3)):N: 1.43 +/- 0.24, H: 3.58 +/- 0.28, HD: 2.29 +/- 0.31.
CONCLUSIONDoxycycline attenuated PH and associated pulmonary vascular remodeling in all rat PH models. The study suggests that high expression and enhanced activity of MMPs may play a brutial role in the development of PH. Such phenomenon seems to be common in a variety of PH models of different etiology.

OBJECTIVETo analyze the relationship between neonatal hypoxia and polycythemia and to study clinical characteristics of Tibetan neonates whose family lived in Tibetan plateau for generations and Han neonates whose family moved to the plateau.
METHODFrom Jan. 2005 to Oct. 2006, totally 739 patients were hospitalized in the ward of neonatology of the hospital. Of these patients, 40 (20 were Tibetan and the other 20 were Han) with neonatal polycythemia. The clinical features, transcutaneous oxygen saturation (TcSO₂), peripheral routine tests and myocardial enzyme profile were studied.
RESULTThe values of hemoglobin (Hb), hematocrit (HCT), and erythrocyte count (RBC) of the Han neonates were significantly higher than those of the Tibetan newborns. Han neonates with polycythemia had lower TcSPO₂ than Tibetan neonates (P < 0.01). Comparison of myocardial enzymes showed that Han neonates had higher CKMB than that of Tibetan groups before treatment (P < 0.01), troponin was not significantly different between the Han and Tibetan groups before treatment (P > 0.05). The major common clinical manifestations of the Han and Tibetan newborns were tachypnea, cyanosis, irritability, weak reflexes and hypoxemia. The Han neonates additionally had poor responses, apnea, lower muscle tone, confusion and asphyxia.
CONCLUSIONThe clinical characteristics, TcSO₂, peripheral blood routine tests and myocardial enzyme profile are helpful in diagnosis and treatment of neonatal polycythemia. Newborn infants born to mothers who moved to the plateau area may be more susceptible to neonatal polycythemia and are prone to impairments of other organs, esp. the functions of the heart and brain.

The present study reports a rare case of Taenia saginata infection, which was initially diagnosed as acute cholecystitis in a Tibetan patient at the Qinghai-Tibetan Plateau pastoral area, China. A 45-year-old female was initially diagnosed with acute cholecystitis at a hospital in China. She had a slight fever, weight loss and constipation and complained of pain in the upper abdomen and left back areas. Increase of monocyte, eosinophil and basophil levels were shown. Taenia sp. eggs were detected in a fecal examination. An adult tapeworm approximately 146 cm in length, whitish-yellow color, was collected from the patient after treatment with traditional Chinese medicine. The adult tapeworm had a scolex and proglottids with genital pores. The scolex was rectangular shape with 4 suckers and rostellum without hooklet. The cox1 gene sequence shared 99.5-99.8% homology with that of T. saginata from other regions in China. The patient was diagnosed finally infected with T. saginata by morphological and molecular charateristics.

OBJECTIVETo study the clinical characteristics and outcomes of BCR/ABL-positive acute lymphoblastic leukemia (BCR/ABL360888725-ALL) and screen the prognostic factors for BCR/ABL360888725-ALL.
METHODSFrom January 2001 to May 2008, 59 patients (median age of 32 years ranging from 3 to 69 years) with the diagnosis of BCR/ABL360888725-ALL by fluorescence in situ hybridization received induction chemotherapy with VDLP-/+Ara-C regimen. The patients who failed to respond to the chemotherapy received subsequent consolidation chemotherapy with imatinib (400-800 mg/day) (17 cases) or allogeneic hematopoietic stem cell transplantation (allo-HSCT) (16 cases).
RESULTSOf the 59 patients, 32 (58.3%) achieved complete remission (CR) after the first induction cycle. In patients with peripheral white blood cell (WBC) count <30=10(9)/L, 30-99.9(9)/L and > or =100(9)/L, the CR rates were 75.0% (18/24), 56.3% (9/15) and 26.3% (5/19) (P=0.006), and the overall survival probability of 2 years ( OSs of 2-yrs) was 24.7%, 22.5% and 21.1%, respectively (P=0.180). According to the FAB classification, 56 cases were divided into L1, L2 and biphenotypic acute leukemia (BAL) subgroups, and their CR rates were 66.7% (6/9), 63.2% (24/38) and 22.2% (2/9) (P=0.029), with OSs of 2-yrs of 22.2%, 27.0% and 22.0%, respectively (P=0.623). In terms of immunophenotype grouping by EGIL, the patients with ALL, myeloid antigen-positive ALL and BAL had CR rates of 61.1% (11/18), 60.6% (20/33) and 12.5% (1/8) (P=0.039), and the OSs of 2-yrs of 22.7%, 21.0% and 18.8%, respectively (P=0.643). In 55 patients with known karyotype, the CR rates were 71.4%(5/7), 70.8% (17/24) and 37.5% (9/24) in normal, sole t(9;22) abnormality, t(9;22) with additional abnormalities groups (P=0.046), with the OSs of 2-yrs of 42.9%, 34.0% and 7.3%, respectively (P=0.000). The patients complicated by septicemia had significantly lower OSs of 2-yrs than those without septicemia (0% vs 38.8%, P=0.005). The OSs of 2-yrs were significantly higher in patients with consolidation chemotherapy with imatinib than those without (48.0% vs 11.2%, P=0.001), and allo-HSCT was associated with significantly higher OSs of 2-yrs than exclusive chemotherapy (54.2% and 8.5%, P=0.000).
CONCLUSIONBCR/ABL360888725-ALL with WBC> or =100 x 10(9)/L, presence of BAL diagnosed by FAB or FACM, t(9;22) with additional chromosome abnormalities all adversely affect the treatment results, and additional chromosome abnormalities and septicemia are associated with lower OSs of 2-yrs. Imatinib treatment and allo-HSCT can both improve the OSs of 2-yrs of the patients with BCR/ABL(+)-ALL.

OBJECTIVETo explore the methodology on prevalence study of chronic obstructive pulmonary disease (COPD) in line with the world, to obtain accurate epidemic data of COPD in China.
METHODSA national multi-center cross-sectional survey on prevalence, risk factors and burden of COPD was conducted in China. In each area, a population-based cluster sample of approximately 1450 individuals aged 40 years or older was interviewed, using standardized questionnaires that were revised on the methodology of burden of lung diseases (BOLD) study and according under the context of China. All participants were submitted to pre-bronchodilator spirometry. Those with airflow limitation received post-bronchodilator spirometry, physical examination, X-rays of chest and EKG (electrocardiogram) tests. The post-bronchodialators FEV1/FVC < 70% was identified as having COPD.
RESULTSInvestigation has been completed with the same standardized procedures by all sites, up to the requirement of quality control. Over 85.0% of the spirometry tests and 95.0% of questionnaires had met the criteria of quality control in each area. Overall, 95.2% of the data was valid with acceptable spirometry and questionaire, and the valid response rate was 79.0%.
CONCLUSIONThe protocol was in line with the international standards, by which the prevalence of COPD in China was of adequate quality and valid.

OBJECTIVETo investigate the stratification risk of catecholamines-beta-adrenoceptor (beta-AR)-cAMP pathway for cardiogenic death events in patients with congestive heart failure (CHF).
METHODSA total of 83 identified CHF patients with a baseline and follow-up plasma levels of norepinephrine (NE) and epinephrine (E), lymphocytes beta-AR density (Bmax), and intralymphocyte cAMP content in peripheral blood were followed up. Major cardiogenic death events were registered.
RESULTSThe period between the initial entry and the last follow-up measurement were 51 +/- 16 months, the total duration of clinical follow-up after the last measurement were 14 +/- 8 months. During follow-up, 39 patients died of cardiogenic (sudden death 17 patients, worsening heart failure 22 patients). Persistence of high NE, E, and cAMP from baseline to follow-up were confirmed as risk predicting factors of cardiovascular events. Persistence NE above 4.0 nmol/L, E above 3.5 nmol/L, and the intralymphocyte cAMP content above 3.5 pmd x mg(-1) x pro(-1) from baseline to follow-up were significant adverse prognostic predictors. The major cardiogenic death events rates per 100 patients-years were 1.33 and 4.82 in patients with NE below and above 4.0 nmol/L (HR: 2.91; 95% CI: 1.08-7.33; P = 0.015); were 1.42 and 4.36 in the patients with E levels below and above 3.5 nmol/L (HR: 2.64; 95% CI: 1.02-6.41; P = 0.019); were 1.81 and 4.67 in the patients with the intralymphocyte cAMP content below and above 3.5 pmd x mg(-1) x pro(-1) (HR: 2.79; 95% CI: 1.04-6.83; P = 0.017), but difference was not significant between the beta-AR density below and above median.
CONCLUSIONSPersistent increase in circulating catecholamines and intralymphocyte cAMP content may increase the long-term mortality in CHF patients.
