OBJECTIVETo observe the curative effect of integrated Chinese and Western medicine on acute cerebral infarction (ACI).

METHODSTwo hundred and seventy-nine ACI patients were assigned to two groups. The control group (140 cases) was treated with Western medicine by staging and the treated group (139 cases) was given TCM therapy according to syndrome differentiation on the basis of Western medicine. The end point was set at the 90th day of the administration. The curative effect was assessed by Chinese stroke scale (CSS), National Institutes of health stroke scale score (NIHSS), Rankin scale and Barthel index (BI).

RESULTSAt the end point of the trial, the total effective rate was 73.38% in the treated group and 61.43% in the control group, the former was superior to the latter (P<0.05). There were 66 cases (47.14%) in the control group and 80 cases (57.55%) in the treated group with improvement rate of NIHSS > or =40%, 65 cases (46.43%) with their Rankin scale within 0-2 grade in the control group and 78 cases (56.12%) in the treated group, 60 cases (42.86%) in the control group and 71 cases (51.08%) in the treated group with BI > or =85, 61 cases (43.57%) in the control group and 72 cases (51.80%) in the treated group with improvement rate of CSS > or = 46%, comparison between them showed significant differences (P < 0.05).

CONCLUSIONTCM therapy accord-ing to syndrome differentiation combined with Western medicine by staging shows better curative efficacy on ACI.

OBJECTIVETo investigate the effect of Bushen Yanggan Recipe (BSYGR) on the function and morphology of nigrostriatal system in Parkinsonian model rats with long-term levodopa treatment.

METHODSUnilateral Parkinsonian rat models were established by injecting 6-hydroxydopamine (6-OHDA) into the substantia nigra pars compacta (SNpc) and ventral segmental area (VTA). Animals were randomly divided into four groups, the sham control group, model control group, levodopa group and levodopa plus BSYGR group. The content of striatal dopa (DA), digydroxy-phenyl acetic acid (DOPAC) and homovanilic acid (HVA) or the THmRNA expression level in the midbrain were measured.

RESULTS(1) Levels of striatal DA, DOPAC, HVA, DOPAC/DA, HVA/DA decreased in the model control group by about 90% as compared with those in sham control group (P < 0.05). These parameters in the levodopa group were higher than those in the sham control group, while in the levodopa plus BSYGR group, they were lower than those in the levodopa group (P < 0.01), approaching the levels in the sham control group (P > 0.05). (2) Striatal TH activity in the model group was lower than that in the sham control group significantly, but higher than that in the levodopa group, while in the levodopa plus BSYGR group, it showed a level obviously higher than that in the levodopa group (P < 0.05). (3) Levodopa plus BSYGR group had a higher midbrain THmRNA expression level than that in the levodopa group.

CONCLUSIONBSYGR could effectively reduce the side effects resulting from the long-term treatment of levodopa.

Objective To clarify the role of insulin resistance on spontaneous recanalization of infarct-relat-ed arteries in the early phase of acute ST-elevation myocardial infarction (STEMI) in patients with normal glucose tolerance. Methods 141 consecutive patients with normal glucose tolerance and acute STEMI were enrolled in our study. Subjects were divided into TIMI 0-1 group (n =91 ) and TIMI 2-3 group (n =50) by primary coronary angi-ngraphy (CAG). The Gemini score and 0-3-vessel disease score estimated the severity and extent of coronary artery disease (CAD). Metabolic parameters and homeostasis model assessment for insulin resistance (IRI) were deter-mined. Results Serum level of fasting insulin, IRI and Gemini score were higher in TIMI 0-1 group than in TIMI 2-3 group [ (11.52±6.22)mU/L vs (7.54±3.65)mU/l,(2.79±2.32) vs (1.73±1.26),(59.17±26.95) vs ( 38.46±22.74) ( P <0.01)]. IRI was positively associated with Gemini score (r=0.185,P <0.05 ). Multivariate Logistic regression analysis revealed that IRI was independent risk factor influencing spontaneous recanalization of in-farct-related urteries(OR=2.87,95% CI=1.09-7.57,P<0.05). Conclusion Insulin resistance is independent risk factor influencing spontaneous recanalizafion of infarct-related arteries in the early phase of acute STEMI in pa-tients with normal glucose tolerance.

OBJECTIVETo observe the therapeutic effect of Yangxue Qingnao granule (YXQNG) in treating chronic cerebrovascular insufficiency (CCI) and its possible mechanism.

METHODSEighty-three patients with CCI were randomly divided into YXQNG and nimodipine (ND) groups, the score of vertigo and the change in cerebral blood velocity before and after treatment were observed. And in the animal experiment, the authors adopted bilateral ligation of cervical carotid communis artery to establish CCI rat models in order to observe the effect of YXQNG and ND on incubation period of vertigo in rats and on memory performance.

RESULTSAfter clinical treatment, the vertigo score of YXQNG group was 2.34, and that of the ND group was 4.18, the comparison between the two groups showed that the difference was significant (P < 0.05). After treatment, the middle cerebral artery mean velocity (MCA Vm) of YXQNG group was 64.78 cm/s, vertebral artery mean velocity (VA Vm) was 29.78 cm/s, while that of ND group was 60.34 cm/s and 23.23 cm/s respectively, the comparison between these two groups showing statistical significance and the difference being obvious (P < 0.05). Experimental study showed that the rats in the model group after 12 weeks learning and memory were markedly lowered, the vertigo incubation period significantly lengthened, and compared with that of the model group, learning and memory of the YXQNG group was markedly improved and vertigo incubation period shortened, with the difference from that of the ND group insignificant, P > 0.05.

CONCLUSIONYXQNG could effectively improve CCI patients' vertigo and other clinical symptoms and increase the cerebral blood flow, lessen the vertigo incubation of model group rats, elevate model group rats' memory performance.

OBJECTIVETo study the impact of gonadotropin-releasing hormone analogs (GnRHa) on body mass index (BMI) in girls with idiopathic central precocious puberty (ICPP).

METHODSOne hundred and thirty-four girls with ICPP were enrolled. Fifty-seven out of the 134 girls were treated with GnRHa for 1.69±0.43 years. The height, weight, bone age and BMI were measured before treatment, at the end of the treatment and after reaching near adult height and compared with those in the untreated 77 girls.

RESULTSThe adult predicted height standard deviation score (SDS) at the end of treatment was significantly higher than that before treatment (P<0.01) and was similar to the target height SDS in the GnRHa treatment group (P>0.05). With GnRHa treatment, the near-adult height SDS was higher than the target height SDS (P<0.01). At the end of treatment, the BMI SDS slightly increased compared with pretreatment level (P>0.05). A significant reduction in the BMI was observed when reaching the near-adult height in the GnRHa treatment group compared to the level of pretreatment and the untreated group (P<0.01). However, the BMI in the GnRHa treatment group before treatment, at the end of the treatment and after reaching near adult height remained in the normal range (±1 SD).

CONCLUSIONSGnRHa may improve the final height in girls with ICPP. The alterations of BMI after GnRHa therapy fluctuate in a normal range.

Objective To investigate the relationship between serum progesterone level at the day with human chorionic gonadotrophin (hCG) administration and pregnant outcome from in in-vitro fertilization-embryo transfer(IVF-ET). Methods From Mar. 2002 to Apr. 2007, 786 cycles with serum progesterone measurement on the day of hCG administration for final oocyte maturation in IVF were analyzed retrospectively in Reproductive Medicine Center in First Affiliated Hospital of Nanjing Medical University.All stimulations were down-regulated with gronadotrophin release hormone agonist (GnRH-a) in both long protocols and short protocols before gonadotrophin stimulation. When the thresholds of serum progesterone were set at 5.5, 6.0,6.5,7.0,7.5,8.0,8.5 and 9.0 nmol/L, respectively. If the level of progesterone was less than the thresholds, those patients were in lower progesterone group, on the contrary, more than the threshold value, those patients were in higher progesterone group. The laboratory results and the clinical outcomes between all patients at lower and higher progesterone group at different thresholds value were analyzed. Results The rate of normal fertilization, quality embryos, successful implantation, chemical pregnancy, clinical pregnancy and live birth did not exhibit remarkable difference between patients with higher and lower serum progesterone level at multiple thresholds on the day of hCG administration in the 786 cycles (P >0.05). However, when the thresholds of serum progesterone were at 8.5 and 9.0 nmol/L, early abortion rates of 27.3% (3/11) and 3/7 in higher progesterone group were significantly higher than 8.8% (26/297) and 8.6% (26/301) in lower progesterone group (P<0.05). And the total abortion rates of 3/7 in higher progesterone group were significantly higher than 11.0% (34/301) in lower progesterone group when the thresholds of serum progesterone were 9.0 nmol/L (P<0.05). Conclusions This study did not prove the correlationship between progesterone level at the clay with hCG administration and the probability of clinical pregnancy or live birth. However, early abortion rates or the total abortion rates were associated with higher progesterone level when the thresholds of serum progesterone were at 8.5 nmol/L or 9.0 nmoL/L.

OBJECTIVETo investigate the role of lung fibroblast activation in radiation-induced lung injury.

METHODSThirty-five male Wistar rats were exposed to a single-dose 30 Gy irradiation of the right hemithorax or sham right lung irradiation. At 1, 7, 14, 28, 56 or 84 days after the irradiation, the rats were sacrificed for examination of alpha-smooth muscle actin (alpha-SMA) expression in the bilateral lung tissues using immunohistochemistry.

RESULTSalpha-SMA expression in fibroblast increased significantly in the out-field and in-field lung tissues within 24 h after irradiation after the irradiation (P<0.001).

CONCLUSIONActivation of the lung fibroblasts occurred within 24 h after irradiation and found in ont-field and in-field lung tissues, suggesting that radiation-induced lung injury may not have an obvious latency.

OBJECTIVETo investigate the factors affecting the prognosis of invasive pulmonary fungal infection (IPFI) in patients after kidney transplantation.

METHODSThis retrospective study involved 80 concurrent patients with IPFI after receiving kidney transplantation in Zhujiang Hospital from January 1, 2000 to April 1, 2010. Fourteen factors including age, gender, pathogens, body temperature on day 5, renal insufficiency, mechanical ventilation, and clinical pulmonary infection score (CPIS) on day 5 were analyzed by univariate analysis and multivariate Logistic regression analysis to identify the factors related to the prognosis.

RESULTSUnivariate analysis showed that a normal body temperature on day 5 of antifungal treatment (P=0.024), fasting high blood glucose (P=0.001), renal insufficiency (P=0.002), malnutrition (P=0.018), time of infection after transplantation (P=0.046), low CPIS on day 5 (P=0.000) and mechanical ventilation (P=0.000) all affected the prognosis of the patients. Logistic regression analysis showed that renal insufficiency (OR=18.096), mechanical ventilation (OR=130.7) and low CPIS on day 5 (OR=0.011) were independent prognostic factors, among which the low CPIS on day 5 was a protective factor.

CONCLUSIONTimely and adequate empirical therapy and renal replacement therapy, along with adjusted anti-fungal therapy protocol according to the CPIS score on day 5, may improve the prognosis of IPFI after kidney transplantation.

OBJECTIVETo establish a highly sensitive and specific assay to detect dengue virus (DENV) envelope protein domain III (EDIII) IgG antibody, and to explore its value in the diagnosis and seroepidemiological survey of dengue.

METHODSThe DENV EDIII IgG antibody capture ELISA was developed using the recombinant full-length DENV EDIII, which was prepared by Pichia yeast expression system as the capture antigen. The serum samples were collected from the same group of 35 DENV-1 patients of primary infection during disease period in 2006 and their follow-up phase in 2010; and the sensitivity of the assay was compared to that of the commercial Panbio DENV IgG ELISA.

RESULTSThe sensitivity of DENV EDIII IgG ELISA in detecting the serum samples from disease period and follow-up phase was 87% (20/23) and 94% (33/35), respectively; whereas the sensitivity of Panbio DENV IgG ELISA was 71% (25/35) and 0, respectively. The sensitivity of DENV EDIII IgG ELISA in detecting the serum samples from both periods was similar, without statistical significance (χ(2) = 0.946, P = 0.331). For serum samples from disease period, the sensitivity of DENV EDIII IgG ELISA was comparable with that of Panbio DENV IgG ELISA (χ(2) = 1.924, P = 0.165). However, DENV EDIII IgG ELISA demonstrated a significantly higher sensitivity than Panbio DENV IgG ELISA in detecting the serum samples from follow-up phase (χ(2) = 62.432, P = 0.000).

CONCLUSIONDENV EDIII IgG capture ELISA is highly sensitive in detecting IgG in the serum samples from either disease period or follow-up phase. This method might be a promising alternative for diagnosis and seroepidemiologic survey of dengue.

OBJECTIVETo establish a nude mouse model of malignant ascites with human ovarian carcinoma cell line OVCAR3 which highly expresses VEGF and evaluate the therapeutic of Avastin combined with cisplan.

METHODSForty-eight nude mice with malignant ascites resulting from intraperitoneal transplantation of human ovarian carcinoma cell line OVCAR3 were treated with intraperitoneal injection of Avastin, cisplan, their combination, and PBS, respectively, to observe the effect on ascites development, VEGF content in the ascites, peritoneal permeability, development of new vessels and number of tumor cells in the ascites.

RESULTSAvastin obviously inhibited ascites accumulation and peritoneal capillary permeability, reduced VEGF protein level and microvascular density in the tumor tissues and the number of red cells and tumor cells in the malignant ascites, and prolonged the survival of the mice. The combination of Avastin and cisplan further enhanced the therapeutic efficacy of Avastin.

CONCLUSIONThe bio-chemotherapeutic strategy with Avastin combined with cisplan can be a promising method for treatment of malignant ascites.
