OBJECTIVETo discuss that pathogenesis evolvement regularity of Chinese miniature swine with phlege-stasis cementation syndrome of coronary heart disease.
METHODEighteen Chinese miniature swine were randomly divided to the normal control group, the model group and the Danlou tablet group, with six swine in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. The levels of BMI, hemorheological parameters, lipids in serum and inflammatory cytokines were observed at the 0th (before the experiment), 2nd (before operation or drug administration), 6th (four weeks after drug administration) and 10th week (eight weeks after drug administration) of study. The levels of TG and TC in liver and the pathological changes in coronary artery tissues were also observed at the end of study.
RESULTCompared with the normal control group, the model group had showed significant increase in the levels of TC, TG, LDL-C and VLDL-C in serum (P < 0.01) from the second week to the end of the experiment, with notable rise in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1). At the 6th week, the levels of BMI and TG and TNF-alpha in serum significantly increased. At the 10th week, the levels of BMI and hs-CRP, IL-6 and TNF-alpha in serum significantly increased as well, with remarkable increase in coronary stenosis, intimal thickness and the ratio between intimal thickness and media thickness (P < 0.05 and P < 0.01), and significant rise in TC and TG in livers (P < 0.01). Compared with the model group, the Danlou tablet group showed obvious reduction in severity of coronary artery lesion, intimal thickness and lumen stenosis ratio and ratio between intimal thickness and media thickness (P < 0.01), BMI, TC, TG, LDL-C and VLDL-C in serum, TC and TG in liver, as well as hs-CRP, IL-6 and TNF-alpha levels in serum (P < 0.05 and P < 0.01), with notable decline in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1).
CONCLUSIONThe interaction of phlegm, blood stasis and toxin syndromes helps promote the progress and development of AS plaques, which is the key pathogenesis of phlegm-stasis cementation syndrome in coronary heart disease.

To explore the effect of glycosyl-phosphatidyl inositol-specific phospholipase D (GPI-PLD) on the adhesion function of bone marrow mononuclear cell from patients with myeloid leukemia and analyze its mechanism, the activity of GPI-PLD in bone marrow mononuclear cell from the patients were measured by using GPI-anchored placental alkaline phosphatase (PLAP) as substrate and Triton-X114 partitioning; the adhesion rate and CD24 expression of these cells were measured by MTT and immunohistochemical method respectively, when these cells were or were not treated by 1 mmol/L 1,10-phenanthroline for 5 hours. The results showed that the GPI-PLD activity of bone marrow mononuclear cells from the patients was significantly inhibited after being treated by 1 mmol/L 1, 10-phenanthroline for 5 hours [(42.08 +/- 7.21)% vs (5.4 +/- 2.96)%], while the adhesion rate and the expression of CD24 of these cells were increased [(49.78 +/- 26.73)% vs (61.19 +/- 29.14)%, (16.02 +/- 9.68)% vs (18.5 +/- 11.14)%, respectively)]. It is concluded that depression of GPI-PLD activity can increase the adhesion rate of bone marrow mononuclear cells from the patients while the CD24 expression is enhanced.

UNLABELLEDOBJECTIVE To observe the clinical efficacy by Qingying Huoxue Decoction (QHD) combined ursodeoxycholic acid (UDCA) in treating patients with early and mid-term primary biliary cirrhosis (PBC). METHODS Totally 78 patients were randomly assigned to the treatment group and the control group, 39 in each group. All patients received basic treatment and took UDCA (at the daily dose of 13-15 mg/kg). Patients in the treatment group took QHD, one dose per day. The treatment course for all was 6 weeks. Clinical efficacy, gamma-glutamyl transferase (γ-GGT), alkaline phospatase (ALP), TBIL, alanine aminotransferase (ALT), and aspartate transaminase (AST) were observed before and after treatment. RESULTS Totally 21 (53. 8%) patients obtained complete response in the treatment group, with statistical difference when compared with that of the control group (11 cases, 30. 8%). Levels of GGT, ALP, ALT, AST, and TBIL decreased in the two groups after treatment (P < 0.01). Levels of ALP, GGT, and TBIL were obviously lower in the treatment group than in the control group (P < 0.05).
CONCLUSIONSQHD combined UDCA in treating early and mid-term PBC patients was superior to the effect of using UDCA alone. It also could improve patients' liver function.

Objective To improve the level of early detection and treatment of pyonephrosis. Methods This study included 41 cases(17 men and 24 women;mean age,49 years)of pyonephrosis.A variety of examinations,including urinary analysis,blood analysis,kidney nuclear medicine scan,ultrasonog- raphy,intravenous urography(IVU),and CT were used for the early diagnosis of pyonephrosis.Pereutaneous nephrostomy(PCN)drainage was done for the interim management of pyonephrosis,then phase 2 operation was performed in 28 cases.The double-J tube was placed in ureter by ureteroscope for drainage,and then phase 2 operation was done in 2 cases.Emergency operation was done in 10 cases.The remaining 1 case un- derwent ESWL after anti-infective therapy.Results Definite diagnosis of pyonephrosis before operation was made by invasive examinations in 31 cases(75.6%),and by percutaneous drainage in 4 cases;the other 6 cases were detected during operation.Only 6 cases(14.6%)underwent nephrectomy;the other 35 cases (85.4%)underwent kidney-sparing operation.Follow-up of 3 months to 9 years was available in 37 cases. No nephrectomy was needed in 33 cases with spared kidney.Serum creatinine was normal in the 4 cases un- dergoing nephrectomy.Conclusions The key to the treatment of pyonephrosis by kidney-sparing surgery is early diagnosis,timely drainage and relief of obstruction.Ultrasonography plays an important role in the early diagnosis of pyonephrosis,and CT has a high sensibility in the diagnosis.Pereutaneons nephrolithotomy (PCNL)secondary to drainage through pereutaneous nephrostomy was beneficial to the patients with kidney stones or upper ureter stones.

OBJECTIVETo analyze the results of clinical and bacteriological examinations in patients with crush syndrome who suffered infectious complications after an earthquake in Sichuan, China.
METHODSA total of 313 bacteriological samples among 147 patients with crush syndrome were collected. Infectious complications, results of microbiological examinations, potential risk factors of infection and mortality were analyzed statistically.
RESULTSIn the obtained database, 112 out of the 147 (75.7%) patients had infectious complications, in which, wound infection, pulmonary infection, and sepsis were most common. The time under the rubble and the time from injury to treatment were related to the occurrence of wound infection (P equal to 0.013, odds ratio 2.25; P equal to 0.017, odds ratio 2.31). Sepsis and wound infection were more common in patients who underwent fasciotomy or amputation than in those who did not (P equal to 0.001).
CONCLUSIONQuick rescue and injury treatment can decrease the infection risk in crush syndrome patients. It is better to obtain microorganic proofs before applying antibiotics, and bacteriological and drug sensitivity data should be taken into account, especially considering that most of these infections are hospital-acquired and drug resistance. Emphasizing the accuracy and efficiency of wound management in emergency situations, cautiously assessing the indications for fasciotomy to avoid open wounds from unnecessary osteofascial compartment decompression incisions may decrease the incidence of infection and ameliorate the prognosis.

OBJECTIVETo distinguish lingual thyroglossal duct cyst (LTDC) from laryngomalacia in newborn infants.
METHODSData of 10 newborn infants with laryngeal stridor and dyspnea, admitted to the department of neonatology in our hospital during December, 2004 to August, 2007, who were finally diagnosed with LTDC though previously diagnosed as congenital laryngeal stridor in other hospitals, were summarized and analyzed.
RESULTSInspiratory stridor with chest wall retractions was cardinal symptom of newborn with LTDC. A slightly gray and round cyst with smooth surface at the base of the tongue was found with laryngoscopy. On computed tomography examination of larynx, a well-circumscribed lesion with low intensity was detected at the base of the tongue protruding into the air passage. Pathological examination demonstrated that the cyst wall was composed of tabular and columnar epithelium.
CONCLUSIONSLTDC is a common disease in newborns, which is similar to laryngomalacia. For neonates suspected of LTDC, laryngoscopic examination should be performed first, while laryngeal CT scan is an important diagnostic basis. Cyst puncture can ameliorate the symptoms of the patients, while surgical removal is the method of radical cure.

Objective To investigate the effects of alcohol extract of bark and male flower of Eucommia ulmoides Oliv. on airway allergic inflammation induced by chicken ovalbumin (OVA) in mice; To explore its mechanism of action. Methods On day 0, day 7, mice were intraperitoneally injected OVA for sensitization, followed by nasal stimulation for 21 days to establish airway allergic inflammation mice models. The mice were divided into normal group, model group, alcohol extract of bark of Eucommia ulmoides Oliv. group, alcohol extract of male flower of Eucommia ulmoides Oliv.group,and Dexamethasone group.Each medication group was given relevant medicine for gavage. The lung tissue was embedded in HE and PAS dyeing, to observe the pathological changes of bronchus and surrounding lung. The levels of serum OVA-IgE, IL-4, IFN-γ and IL-13 were measured by ELISA. The expression of ICAM-1, VEGF, MMP9 and TIMP1 were detected by immunohistochemistry. Flow cytometry was used to detect the expression of Th17 cells in peripheral blood. The expressions of TNF-α and IL-6 mRNA in lung tissue were detected by RT-PCR. Results The model group showed changes of airway allergic inflammatory such as eosinophils and other inflammatory cell infiltration, bronchial spasm, and mucus secretion. Lung histopathology in alcohol extract of bark and male flower of Eucommia ulmoides Oliv.groups was improved significantly(P<0.05).Compared with the normal group, the levels of serum OVA-IgE, IL-4 and IL-13 increased in model group, while the level of IFN-γ decreased (P<0.05, P<0.01). The expressions of ICAM-1, VEGF and MMP9 increased, while the expression of TIMP1 decreased (P<0.01); peripheral blood IL-17+cells increased (P<0.01); the expressions of TNF-α and IL-6 mRNA increased. Compared with the model group, the levels of serum OVA-IgE, IL-4 and IL-13 decreased in alcohol extract of bark and male flower of Eucommia ulmoides Oliv. groups (P<0.05, P<0.01); the expressions of ICAM-1 and VEGF decreased (P<0.05, P<0.01); the expression of TIMP1 increased. Alcohol extract of bark and male flower of Eucommia ulmoides Oliv.could down-regulate IL-17+cells,reduce the expression of IL-6 mRNA(P<0.05,P<0.01). Alcohol extract of bark of Eucommia ulmoides Oliv. group could induce the secretion of IFN-γ (P<0.01), and down-regulate the expression of TNF-α mRNA(P<0.05).Alcohol extract of male flower of Eucommia ulmoides Oliv. group could significantly down-regulate the expression of MMP9 (P<0.05). Conclusion Alcohol extract of bark and male flower of Eucommia ulmoides Oliv.can induce the production of OVA-IgE,inhibit secretion of Th2 cytokines, inhibit the expression of adhesion molecules, depress Th17 cells, so as to inhibit the airway allergic inflammation.

OBJECTIVETo investigate the effect of transurethral resection of the prostate (TURP) in the treatment of advanced prostate cancer with bladder outlet obstruction (BOO).
METHODSWe included in this study 43 cases of advanced prostate cancer with BOO treated by TURP, and analyzed their IPSS, maximum urinary flow rate and relevant risk factors pre-operatively and at 3 and 12 months after TURP.
RESULTSCompared with the baseline, IPSS and the maximum urinary flow rate of the patients showed significant differences 3 months after surgery ([19.60 +/- 0.41] score vs. [9.58 +/- 0.33] score, [4.93 +/- 0.68] ml/s vs. [8.96 +/- 0.47] ml/s, P < 0.05), but not at 12 months ([15.73 +/- 0.66] score, [5.67 +/- 0.44] ml/s). In multiple regression analysis, a good outcome was associated with pre-operative acute urinary retention, while poor prognosis with hormone-refractory prostate cancer.
CONCLUSIONIn the treatment of advanced hormone-refractory prostate cancer with BOO, TURP can reduce IPSS and increase the maximum urinary flow rate in the early period after surgery, but its long-term effect is not so desirable. Meanwhile the operation itself may bring about relevant complications and reduce the patient's quality of life.
